By introducing an SMA wire drive motor into the camera drive motor, optical image stabilization is achieved. The SMA wire drive motor has a simple structure and occupies a small area, enabling miniaturization of the camera drive motor. Furthermore, by providing multiple ball bearings, the friction coefficient of the base movement can be reduced, thereby improving the quality of captured images.

为达到上述目的,本申请的实施例采用如下技术方案:To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

一方面,本申请提供了一种摄像头驱动马达。比如,该摄像头驱动马达可以被应用在具有拍照、摄像功能的电子设备中。In one aspect, the present application provides a camera drive motor, which can be used, for example, in electronic devices with photo and video recording functions.

When the anti-shake drive structure drives the seat, carrier and lens to move along a plane perpendicular to the lens optical axis, the seat slides along the multiple balls.

利用设置在座体和基座之间的多个滚珠,可以减小座体与基座之间的摩擦系数,提升摄像质量。By utilizing a plurality of balls arranged between the seat body and the base, the friction coefficient between the seat body and the base can be reduced, thereby improving the camera quality.

在一种可以实现的方式中,多个滚珠包括第一组滚珠、第二组滚珠和第三组滚珠,第一组滚珠、第二组滚珠和第三组滚珠中的任一组包括多个滚珠,第一组滚珠、第二组滚珠和第三组滚珠沿着基座的周向间隔布设。In one possible implementation, the plurality of balls include a first group of balls, a second group of balls, and a third group of balls, any one of the first group of balls, the second group of balls, and the third group of balls includes a plurality of balls, and the first group of balls, the second group of balls, and the third group of balls are arranged at intervals along the circumference of the base.

In this way, on the basis of reducing the friction coefficient of the seat movement, the stability of the seat movement can also be improved by utilizing the stability of the triangle.

在一种可以实现的方式中,座体和基座之间设置有镶嵌槽,多个滚珠设置在镶嵌槽内。In one possible implementation, an inlay groove is provided between the seat body and the base, and a plurality of balls are provided in the inlay groove.

比如,可以在座体的朝向基座的表面设置镶嵌槽,将多个滚珠设置在该镶嵌槽内。For example, an inlay groove may be provided on the surface of the seat body facing the base, and a plurality of balls may be provided in the inlay groove.

When the anti-shake drive structure drives the seat body to slide along the multiple ball bearings, the magnetic structure generates a magnetic force between the base and the seat body.

通过在基座和载体之间设置磁吸结构,那么,当座体相对基座移动时,在该磁吸结构的磁吸力作用下,降低座体在自身重力下发生倾斜的风险。By arranging a magnetic attraction structure between the base and the carrier, when the base moves relative to the base, the risk of the base tilting under its own gravity is reduced due to the magnetic attraction force of the magnetic attraction structure.

在一种可以实现的方式中,磁吸结构包括磁石和磁吸片,磁石和磁吸片的一者设置在基座上,另一者设置在座体上。In one practicable manner, the magnetic attraction structure includes a magnet and a magnetic attraction sheet, one of the magnet and the magnetic attraction sheet is arranged on the base, and the other is arranged on the base.

比如,可以在基座上设置安装槽,磁石设置在该安装槽内,这样可以压缩整个摄像头驱动马达的厚度尺寸。For example, a mounting groove may be provided on the base, and the magnet may be provided in the mounting groove, thereby compressing the thickness of the entire camera drive motor.

在一种可以实现的方式中,多个滚珠包括多组滚珠,多组滚珠沿着基座的周向间隔布设,相邻两组滚珠之间设置有磁吸结构。In one possible implementation, the plurality of balls include a plurality of groups of balls, the plurality of groups of balls are spaced apart along the circumference of the base, and a magnetic attraction structure is provided between two adjacent groups of balls.

在一种可以实现的方式中,摄像头驱动马达还包括对焦驱动结构、第一弹性件和第一滑杆,第一弹性件用于给载体和镜头自第一位置移动至第二位置的弹力,第一位置至第二位置平行于沿着镜头的光轴,第一位置相比第二位置靠近座体,对焦驱动结构驱动载体和镜头沿着镜头的光轴在第二位置和第三位置之间移动,第二位置处于第一位置和第三位置之间;第一滑杆的轴向与镜头的光轴方向平行,第一滑杆设置于座体与载体之间;载体和镜头在第一位置和第三位置之间移动时,载体沿着第一滑杆的轴向滑动。In one achievable method, the camera drive motor also includes a focus drive structure, a first elastic member and a first sliding rod, the first elastic member is used to provide elastic force for the carrier and the lens to move from the first position to the second position, the first position to the second position is parallel to the optical axis along the lens, the first position is closer to the base body than the second position, the focus drive structure drives the carrier and the lens to move along the optical axis of the lens between the second position and the third position, and the second position is between the first position and the third position; the axial direction of the first sliding rod is parallel to the optical axis direction of the lens, and the first sliding rod is arranged between the base body and the carrier; when the carrier and the lens move between the first position and the third position, the carrier slides along the axial direction of the first sliding rod.

承载有镜头的载体的行程不仅包括在第二位置和第三位置之间的对焦行程,还包括在第一位置和第二位置之间的弹性件复位行程,即承载有镜头的载体在第一位置和第三位置之间移动,相比仅有的在第二位置和第三位置之间的对焦行程,本申请的镜头行程较大。The travel of the carrier carrying the lens includes not only the focusing travel between the second position and the third position, but also the elastic member reset travel between the first position and the second position, that is, the carrier carrying the lens moves between the first position and the third position. Compared with the focusing travel only between the second position and the third position, the lens travel of the present application is larger.

另外,本申请的摄像头驱动马达还包括第一滑杆,第一滑杆的轴向与镜头的光轴方向一致,第一滑杆相对于座体固定,载体与第一滑杆滑动连接;载体和镜头在第一位置和第三位置之间移动时,载体沿着第一滑杆的轴向滑动。In addition, the camera drive motor of the present application also includes a first slide rod, the axial direction of the first slide rod is consistent with the optical axis direction of the lens, the first slide rod is fixed relative to the base body, and the carrier is slidingly connected to the first slide rod; when the carrier and the lens move between the first position and the third position, the carrier slides along the axial direction of the first slide rod.

由于载体与第一滑杆滑动配合,承载有镜头的载体可以沿着第一滑杆滑动,那么,即使载体和镜头的行程较大,或者带动载体和镜头移动的驱动力较大,镜头和载体移动稳定性也较高,降低载体和镜头出现偏离光轴的风险。Since the carrier and the first sliding rod are in sliding cooperation, the carrier carrying the lens can slide along the first sliding rod. Therefore, even if the stroke of the carrier and the lens is large, or the driving force that drives the carrier and the lens to move is large, the movement stability of the lens and the carrier is also high, reducing the risk of the carrier and the lens deviating from the optical axis.

在一种可以实现的方式中,第一弹性件位于座体下方,载体和镜头位于第一位置时,载体与第一弹性件接触,第一弹性件发生形变,产生自第一位置指向第二位置的弹力。In one possible implementation, the first elastic member is located below the base. When the carrier and the lens are in the first position, the carrier contacts the first elastic member, and the first elastic member deforms, generating an elastic force directed from the first position to the second position.

第一弹性件位于座体下方,当载体和镜头处于第一位置时,挤压弹性件,使得弹性件产生弹力。The first elastic member is located below the base body. When the carrier and the lens are in the first position, the elastic member is squeezed so that the elastic member generates elastic force.

在一种可以实现的方式中,载体和镜头在第二位置和第三位置之间移动时,载体与第一弹性件分离。In one achievable manner, when the carrier and the lens move between the second position and the third position, the carrier is separated from the first elastic member.

即就是,当对焦驱动结构带动载体和镜头沿着镜头的光轴移动,实现自动对焦时,弹性件不会对载体和镜头产生弹力。That is, when the focus driving structure drives the carrier and the lens to move along the optical axis of the lens to achieve automatic focusing, the elastic member will not generate elastic force on the carrier and the lens.

在一种可以实现的方式中,第一弹性件包括第一支耳和第二支耳,以及连接在第一支耳和第二支耳之间的弹性段,第一支耳和第二支耳均固定在座体上,弹性段延伸至载体的下方;载体和镜头位于第一位置时,载体与弹性段接触,弹性段发生形变,产生自第一位置指向第二位置的弹力。In one possible implementation, the first elastic member includes a first ear, a second ear, and an elastic section connected between the first ear and the second ear, the first ear and the second ear are both fixed to the base, and the elastic section extends to the bottom of the carrier; when the carrier and the lens are in the first position, the carrier contacts the elastic section, the elastic section is deformed, and an elastic force is generated from the first position to the second position.

在一种可以实现的方式中,摄像头驱动马达还包括吸引结构,吸引结构用于与第一滑杆产生吸引力;载体和镜头沿着镜头的光轴移动时,载体在吸引力的吸引下沿着第一滑杆的轴向滑动。In one practicable manner, the camera drive motor further includes an attraction structure, which is used to generate attraction with the first slide bar; when the carrier and the lens move along the optical axis of the lens, the carrier slides along the axial direction of the first slide bar under the attraction.

承载有镜头的载体相对座体沿着镜头的光轴方向移动时,为了使得载体稳定的沿着滑杆滑动,在该实现方式中,通过设置吸引结构,该吸引结构可以与滑杆之间产生吸引力,在此吸引力的作用下,载体会沿着滑杆滑动。When the carrier carrying the lens moves relative to the base along the optical axis of the lens, in order to make the carrier slide stably along the sliding rod, in this implementation, an attraction structure is set up, which can generate attraction between the attraction structure and the sliding rod. Under the action of this attraction, the carrier will slide along the sliding rod.

在一种可以实现的方式中,吸引结构包括磁体,磁体固定在载体上,并靠近第一滑杆设置,磁体与第一滑杆之间产生有吸引力。In one possible implementation, the attraction structure includes a magnet, which is fixed on the carrier and disposed close to the first sliding bar, and an attractive force is generated between the magnet and the first sliding bar.

承载有镜头的载体相对座体沿着镜头的光轴方向移动时,为了使得载体稳定的沿着滑杆滑动,本申请实施例中,通过设置磁体,使得磁体与滑杆之间产生吸引力(可以称为抱轴力),从而,可以使得载体在移动过程中,抱紧滑杆,沿着滑杆稳定的滑动,提升移动稳定性。When the carrier carrying the lens moves relative to the base along the optical axis of the lens, in order to make the carrier slide stably along the slide bar, the present invention In the embodiment, a magnet is provided to generate an attractive force (which may be called an axial holding force) between the magnet and the slide bar, so that the carrier can hold the slide bar tightly during movement and slide stably along the slide bar, thereby improving movement stability.

对焦驱动结构中的线圈和磁石之间产生电磁感应,滑杆与磁体之间可以产生磁吸力,为了削弱电磁感应与磁吸力之间的影响,本申请示例中,吸引结构的磁体相比对焦驱动单元,更加靠近滑杆。Electromagnetic induction is generated between the coil and the magnet in the focus drive structure, and magnetic attraction can be generated between the slide bar and the magnet. In order to weaken the influence between the electromagnetic induction and the magnetic attraction, in the example of this application, the magnet of the attraction structure is closer to the slide bar than the focus drive unit.

在一种可以实现的方式中,对焦驱动结构包括第一磁石和与第一磁石面对面的第一线圈,以及包括第二磁石和与第二磁石面对面的第二线圈,第一磁石和第二磁石关于镜头的光轴对称设置;摄像头驱动马达还包括第二滑杆;第一滑杆设置在第一磁石的旁侧,第二滑杆设置在第二磁石的旁侧,第一滑杆和第二滑杆关于镜头的光轴对称设置。In one achievable method, the focus drive structure includes a first magnet and a first coil facing the first magnet, and a second magnet and a second coil facing the second magnet, and the first magnet and the second magnet are symmetrically arranged about the optical axis of the lens; the camera drive motor also includes a second slide rod; the first slide rod is arranged next to the first magnet, and the second slide rod is arranged next to the second magnet, and the first slide rod and the second slide rod are symmetrically arranged about the optical axis of the lens.

承载有镜头的载体的行程不仅包括在第二位置和第三位置之间的对焦行程,还包括在第一位置和第二位置之间的弹性件复位行程,即承载有镜头的载体在第一位置和第三位置之间移动,相比仅有的在第二位置和第三位置之间的对焦行程,本申请的镜头行程较大。The travel of the carrier carrying the lens includes not only the focusing travel between the second position and the third position, but also the elastic member reset travel between the first position and the second position, that is, the carrier carrying the lens moves between the first position and the third position.

Driven by the focus drive structure, when the movable part moves along the Z direction relative to the fixed part, the lens 40 can be driven to move along the Z direction at the same time to achieve automatic focusing.

如图7所示,图7示例性的展示了对焦驱动结构的一种可以实现的结构。对焦驱动结构包括多组对焦驱动单元,多组对焦驱动单元沿着载体415的周向间隔排布。在一些示例中,多组对焦驱动单元可以关于镜头的光轴O1-O2对称设置。As shown in Figure 7, Figure 7 exemplifies a possible structure of a focus drive structure. The focus drive structure includes multiple groups of focus drive units, which are arranged at intervals along the circumference of the carrier 415. In some examples, the multiple groups of focus drive units can be symmetrically arranged about the optical axis O1-O2 of the lens.

比如,在图7中,包括两组对焦驱动单元,两组对焦驱动单元包括:对焦驱动单元418A和对焦驱动单元418B,对焦驱动单元418A和对焦驱动单元418B相对设置,示例的,对焦驱动单元418A和对焦驱动单元418B可以关于镜头的光轴O1-O2对称设置。For example, in FIG7 , two groups of focus drive units are included, and the two groups of focus drive units include: a focus drive unit 418A and a focus drive unit 418B, and the focus drive unit 418A and the focus drive unit 418B are arranged opposite to each other. The units 418B may be arranged symmetrically about the optical axis O1 - O2 of the lens.

本申请示例中,每组对焦驱动单元包括磁石4181和线圈4182,磁石4181和线圈4182中的一者设置在座体414上,另一者设置在载体415上。比如,在图7中,磁石4181设置在载体415上,线圈4182设置在座体414上。In this example, each focus drive unit includes a magnet 4181 and a coil 4182, one of which is disposed on the base 414 and the other on the carrier 415. For example, in FIG7 , the magnet 4181 is disposed on the carrier 415, and the coil 4182 is disposed on the base 414.

磁石4181在载体415上的设置方式具有多种。例如,在图7示例中,在载体415的朝向座体414的壁面上开设有第一安装槽419,磁石4181位于第一安装槽419内。There are many ways to dispose the magnet 4181 on the carrier 415. For example, in the example shown in FIG7 , a first mounting groove 419 is formed on the wall of the carrier 415 facing the base 414, and the magnet 4181 is located in the first mounting groove 419.

图7示例的给出了线圈4182的一种布设方式,在座体414的朝向载体415的壁面上开设第二安装槽420,线圈4182位于第二安装槽420内。FIG. 7 shows an example of a layout of the coil 4182 . A second mounting groove 420 is provided on the wall of the base 414 facing the carrier 415 , and the coil 4182 is located in the second mounting groove 420 .

本申请示例中,该摄像头模组在自动对焦时,通过磁石4181和线圈4182产生的安培力,使得承载有镜头的载体415沿着镜头的光轴O1-O2上下移动,实现自动对焦。In the example of this application, when the camera module is automatically focusing, the Ampere force generated by the magnet 4181 and the coil 4182 causes the carrier 415 carrying the lens to move up and down along the optical axis O1-O2 of the lens, thereby achieving automatic focusing.

本申请示例的摄像头驱动马达中,不仅包括实现自动对焦的对焦驱动结构,还包括实现光学防抖的防抖驱动结构。The camera drive motor of the example of this application includes not only a focus drive structure for realizing autofocus, but also an anti-shake drive structure for realizing optical image stabilization.

本申请示例中,防抖驱动结构连接基座413和座体414,防抖驱动结构驱动座体414、载体415和镜头40沿着与镜头的光轴O1-O2垂直的XY平面移动,实现防抖补偿。In the example of this application, the anti-shake driving structure connects the base 413 and the seat body 414. The anti-shake driving structure drives the seat body 414, the carrier 415 and the lens 40 to move along the XY plane perpendicular to the optical axis O1-O2 of the lens to achieve anti-shake compensation.

在一些实施例中,如图8,图8示例性的展示了防抖驱动结构的一种可以实现的结构。防抖驱动结构可以包括多组防抖驱动单元,多组防抖驱动单元可以围绕基座的周向排列。In some embodiments, as shown in FIG8 , which exemplarily illustrates an achievable structure of an anti-shake drive structure, the anti-shake drive structure may include multiple groups of anti-shake drive units, which may be arranged around the circumference of the base.

比如,在图8中,防抖驱动结构包括四组防抖驱动单元,分别为防抖驱动单元421A、防抖驱动单元421B、防抖驱动单元421C和防抖驱动单元421D。防抖驱动单元421A、防抖驱动单元421B、防抖驱动单元421C和防抖驱动单元421D沿着基座的周向排布。For example, in Figure 8, the anti-shake drive structure includes four groups of anti-shake drive units: anti-shake drive unit 421A, anti-shake drive unit 421B, anti-shake drive unit 421C, and anti-shake drive unit 421D. Anti-shake drive unit 421A, anti-shake drive unit 421B, anti-shake drive unit 421C, and anti-shake drive unit 421D are arranged along the circumference of the base.

继续见图8,每组防抖驱动单元包括定卡爪4211和动卡爪4213,以及连接定卡爪4211和动卡爪4213的形状记忆合金(shape memory alloy,SMA)线4212。SMA线4212的一端与动卡爪4213连接,另一端与定卡爪4211连接。Continuing with FIG8 , each anti-shake drive unit includes a fixed jaw 4211, a movable jaw 4213, and a shape memory alloy (SMA) wire 4212 connecting the fixed jaw 4211 and the movable jaw 4213. One end of the SMA wire 4212 is connected to the movable jaw 4213, and the other end is connected to the fixed jaw 4211.

本申请示例的防抖驱动结构采用SMA驱动组件,以形成SMA驱动马达。SMA驱动组件具有驱动力大、体积小等特点,这样,可以压缩整个摄像头驱动马达的体积。The anti-shake drive structure of the present application example uses an SMA drive assembly to form an SMA drive motor. The SMA drive assembly has the characteristics of large driving force and small size, so the size of the entire camera drive motor can be compressed.

在一些可以实现的结构中,如图8,每组防抖驱动单元可以包括一个动卡爪4213、一个定卡爪4211和一条SMA线4212,一条SMA线4212连接在一个动卡爪4213和一个定卡爪4211之间。本申请示例的驱动结构为4线SMA驱动组件,4线SMA驱动组件结构简单,占据面积较小。In some possible structures, as shown in FIG8 , each anti-shake drive unit may include a movable claw 4213, a fixed claw 4211, and an SMA wire 4212, with an SMA wire 4212 connected between a movable claw 4213 and a fixed claw 4211. The drive structure of the example in this application is a 4-wire SMA drive assembly, which has a simple structure and occupies a small area.

继续见图8,相邻两组防抖驱动单元的动卡爪4213靠近设置,并连接在一起。比如,防抖驱动单元421A和防抖驱动单元421D相邻,防抖驱动单元421A的动卡爪4213和防抖驱动单元421D的动卡爪4213连接在一起。或者,在一些示例中,防抖驱动单元421A的动卡爪4213和防抖驱动单元421D的动卡爪4213为一体结构件。Continuing with FIG8 , the movable claws 4213 of two adjacent sets of anti-shake drive units are arranged close together and connected together. For example, the anti-shake drive unit 421A and the anti-shake drive unit 421D are adjacent to each other, and the movable claws 4213 of the anti-shake drive unit 421A and the movable claws 4213 of the anti-shake drive unit 421D are connected together. Alternatively, in some examples, the movable claws 4213 of the anti-shake drive unit 421A and the movable claws 4213 of the anti-shake drive unit 421D are integrally formed.

见图8,相邻两组防抖驱动单元的定卡爪4211靠近设置,并分离开。比如,防抖驱动单元421A和防抖驱动单元421B相邻,防抖驱动单元421A的定卡爪4211和防抖驱动单元421B的定卡爪4211彼此靠近,且两个定卡爪4211为彼此独立的结构件。As shown in Figure 8 , the fixed claws 4211 of two adjacent groups of anti-shake drive units are arranged close to each other and separated. For example, the anti-shake drive unit 421A and the anti-shake drive unit 421B are adjacent to each other, and the fixed claws 4211 of the anti-shake drive unit 421A and the fixed claws 4211 of the anti-shake drive unit 421B are close to each other, and the two fixed claws 4211 are independent structural components.

在一些示例中,定卡爪4211可以作为SMA线4212的第一电极的接线端子,动卡爪4213可以作为SMA线4212的第二电极的接线端子。比如,定卡爪4211可以作为SMA线的正极的接线端子,动卡爪4213可以作为SMA线的负极的接线端子。In some examples, the fixed jaw 4211 can serve as a terminal for a first electrode of the SMA wire 4212, and the movable jaw 4213 can serve as a terminal for a second electrode of the SMA wire 4212. For example, the fixed jaw 4211 can serve as a terminal for the positive electrode of the SMA wire, and the movable jaw 4213 can serve as a terminal for the negative electrode of the SMA wire.

如图8所示,防抖驱动单元421A和防抖驱动单元421D相邻设置,防抖驱动单元421A的动卡爪4213和防抖驱动单元421D的动卡爪4213连接在一起。例如,防抖驱动单元421A的定卡爪4211作为正极接线端子,防抖驱动单元421D的定卡爪4211作也为正极接线端子,连接在一起的防抖驱动单元421A的动卡爪4213和防抖驱动单元421D的动卡爪4213作为负极接线端子。本申请示例中,SMA线4212是由SMA制成的丝线结构。SMA可以是一种镍钛合金材料,具有热缩冷涨的特点。当SMA线内未通入电流时,SMA线处于松弛状态。当电流流入SMA线时,SMA线因具有电阻特性,而将部分电能转换为热能,SMA线在自身热能作用下收缩,以向座体414施加拉力,由此可以带动座体414向四周任意方向移动,实现光学防抖。As shown in Figure 8, the anti-shake drive unit 421A and the anti-shake drive unit 421D are arranged adjacent to each other, and the movable claw 4213 of the anti-shake drive unit 421A and the movable claw 4213 of the anti-shake drive unit 421D are connected together. For example, the fixed claw 4211 of the anti-shake drive unit 421A serves as the positive terminal, and the fixed claw 4211 of the anti-shake drive unit 421D also serves as the positive terminal, and the movable claw 4213 of the anti-shake drive unit 421A and the movable claw 4213 of the anti-shake drive unit 421D connected together serve as the negative terminal. In the example of this application, the SMA wire 4212 is a wire structure made of SMA. SMA can be a nickel-titanium alloy material with the characteristics of thermal contraction and cold expansion. When no current is passed through the SMA wire, the SMA wire When current flows into the SMA wire, the SMA wire converts part of the electrical energy into heat due to its resistance. The SMA wire contracts under the action of its own heat energy, exerting a tensile force on the base 414, thereby driving the base 414 to move in any direction around it, achieving optical image stabilization.

通过限定四根SMA线的位置关系,使得SMA驱动组件可以通过控制四根SMA线内的电信号,使得四根SMA线对座体的合力沿XY平面移动。由于座体414与承载有镜头的载体415可以同时相对基座413平移,故而SMA驱动组件能够驱动镜头组件平移,使得摄像头模组实现光学防抖。By defining the positional relationship of the four SMA wires, the SMA drive assembly can control the electrical signals within the four SMA wires, causing the combined force of the four SMA wires on the base to move along the XY plane. Because the base 414 and the carrier 415 carrying the lens can simultaneously translate relative to the base 413, the SMA drive assembly can drive the lens assembly to translate, enabling optical image stabilization of the camera module.

防抖驱动结构421的动卡爪4213、定卡爪4211和SMA线4212布设方式具有多种情况。There are many ways to arrange the movable claw 4213 , the fixed claw 4211 and the SMA wire 4212 of the anti-shake driving structure 421 .

如图9和图10,图9示出了防抖驱动结构和其他结构件的分解图,图10是将图9所示结构旋转180°后的可视图。As shown in Figures 9 and 10, Figure 9 shows an exploded view of the anti-shake drive structure and other structural components, and Figure 10 is a visible view of the structure shown in Figure 9 after being rotated 180 degrees.

结合图9和图10,定卡爪4211位于基座413的下表面,并与基座413固定连接。可以理解为:基座413具有相对的上表面和下表面,上表面靠近光线的入光侧,下表面靠近光线的出光侧,定卡爪4211固定在基座413的下表面。9 and 10 , the fixed claw 4211 is located on the lower surface of the base 413 and is fixedly connected to the base 413. It can be understood that the base 413 has an upper surface and a lower surface that are opposite to each other, the upper surface is close to the light incident side, and the lower surface is close to the light exit side, and the fixed claw 4211 is fixed to the lower surface of the base 413.

如图9和图10,动卡爪4213的部分位于座体414的下表面,并与座体414固定连接。座体414的下表面可以理解靠近光线出光侧的表面。9 and 10 , the movable claw 4213 is located on the lower surface of the base 414 and is fixedly connected to the base 414. The lower surface of the base 414 can be understood as the surface close to the light emitting side.

如图11,图11是本申请给出的动卡爪4213的一种可以实现的结构,其中,动卡爪4213包括第一部分4213A和第二部分4213B,以及连接第一部分4213A和第二部分4213B的第三部分4213C,第一部分4213A和第二部分4213B位于基座413的下表面,并分别与SMA线4212连接,第三部分4213C位于座体414的下表面,并与座体414固定连接。As shown in Figure 11, Figure 11 is a feasible structure of the movable clamping claw 4213 given in the present application, wherein the movable clamping claw 4213 includes a first part 4213A and a second part 4213B, and a third part 4213C connecting the first part 4213A and the second part 4213B. The first part 4213A and the second part 4213B are located on the lower surface of the base 413 and are respectively connected to the SMA wire 4212. The third part 4213C is located on the lower surface of the seat body 414 and is fixedly connected to the seat body 414.

为了使得动卡爪4213的第三部分4213C与座体414固定连接,如图9和图10,可以在基座413上开设腔室422,座体414上设置有可以穿过腔室422的延伸部423,第三部分4213C朝腔室422方向凸出,并且,第三部分4213C延伸至延伸部423的下方,并与延伸部423固定连接。在图9和图10示出的两条黑色虚线示意延伸部423与动卡爪4213的连接关系。In order to securely connect the third portion 4213C of the movable jaw 4213 to the base 414, as shown in Figures 9 and 10, a cavity 422 may be provided on the base 413, and an extension 423 that can pass through the cavity 422 may be provided on the base 414. The third portion 4213C protrudes toward the cavity 422, and the third portion 4213C extends below the extension 423 and is securely connected to the extension 423. The two black dashed lines shown in Figures 9 and 10 illustrate the connection between the extension 423 and the movable jaw 4213.

继续参阅图9和图10,SMA线4212位于基座413的下表面,本申请示例中,SMA线4212的延伸方向平行于所在基座侧边的延伸方向。9 and 10 , the SMA wire 4212 is located on the lower surface of the base 413 . In this example, the extension direction of the SMA wire 4212 is parallel to the extension direction of the side of the base.

摄像头模组在执行光学防抖功能时,承载有镜头组件的载体415,以及座体414会相对基座413产生移动,载体415和基座413之间具有摩擦力,摩擦力的大小影响摄像效果,比如,摩擦力较大时,导致摄像头模组的预览画面存在微弱的抖动(jitter)。When the camera module performs the optical image stabilization function, the carrier 415 carrying the lens assembly and the base 414 will move relative to the base 413. There is friction between the carrier 415 and the base 413. The magnitude of the friction affects the camera effect. For example, when the friction is large, the preview image of the camera module will have slight jitter.

下述简单介绍摩擦力如何影响摄像质量。The following is a brief introduction to how friction affects camera quality.

防抖驱动结构中,通过相对的两根SMA线的实际长度差实现镜头的位置控制,SMA线的长度与电阻相关,在一定范围内,SMA线的长度与电阻呈线性关系,即就是SMA线的长度越长,电阻越大,从而,给所示的四根SMA线不同的驱动控制信号时,相对位置的两根SMA线的电阻差可以作为SMA线的长度差的反馈信号。In the anti-shake drive structure, the position of the lens is controlled by the actual length difference between two opposing SMA wires. The length of the SMA wire is related to the resistance. Within a certain range, the length of the SMA wire and the resistance are linearly related. That is, the longer the SMA wire, the greater the resistance. Therefore, when different drive control signals are given to the four SMA wires shown, the resistance difference between the two SMA wires in relative positions can be used as a feedback signal of the SMA wire length difference.

由于座体414和基座413之间存在摩擦力,使得控制信号的目标位置与镜头的实际移动位置存在偏差,因此,电阻反馈信号与驱动控制信号之间不断地进行反馈-补偿。因此当存在与运动方向相反的摩擦力较大时,由于受到阻力,镜头本该移动精准的移动到某个位置,但实际还差一点。此时控制系统通过电阻检测到镜头未移动到该理论位置,随即增加驱动信号使SMA线的拉力增大一点,使镜头移动到该理论位置,且由于存在摩擦力,此补偿相比无摩擦力时补偿更大。但补偿可能存在过度补偿,当补偿过大时,又会降低SMA线的驱动力,此时镜头会反向移动、从而靠近理论位置,此时摩擦力方向改变,对补偿效果的影响会比无摩擦力大。摩擦力的存在会降低控制精度与补偿精度,因电阻反馈-补偿是实时进行的,即以上补偿动作时持续进行的,最终导致的结果就是实际的镜头位置会在理论位置来回波动、导致摄像头模组的预览画面存在微弱的抖动(jitter)。因摩擦力的存在,这种抖动程度相比于无摩擦或者摩擦很小时更为严重。Due to friction between the base 414 and the base 413, there is a deviation between the target position of the control signal and the actual movement position of the lens. Therefore, feedback and compensation are continuously performed between the resistor feedback signal and the drive control signal. Therefore, when there is a large friction force opposite to the direction of motion, the lens, which should move precisely to a certain position, is actually slightly off due to resistance. At this point, the control system detects through the resistor that the lens has not moved to the theoretical position and then increases the drive signal slightly, increasing the tension of the SMA cable to move the lens to the theoretical position. Due to the presence of friction, this compensation is greater than when there is no friction. However, there is the possibility of overcompensation. When the compensation is too large, it reduces the driving force of the SMA cable, causing the lens to move in the opposite direction, closer to the theoretical position. The direction of the friction then changes, which has a greater impact on the compensation effect than when there is no friction. The presence of friction reduces control and compensation accuracy. Because the resistor feedback and compensation are performed in real time, that is, the compensation action is continuous, the ultimate result is that the actual lens position fluctuates back and forth from the theoretical position, causing slight jitter in the camera module preview image. Due to the existence of friction, this vibration is more severe than when there is no friction or very little friction.

为了降低摩擦,弱化抖动,本申请实施例给出了一些可以降低座体414移动摩擦系数的结构,从而提升光学防抖性能,提升画面质量。In order to reduce friction and weaken shaking, the embodiments of the present application provide some structures that can reduce the friction coefficient of the seat 414 movement, thereby improving the optical image stabilization performance and improving the picture quality.

如图12所示,图12示例性的展示了基座413和座体414的分解图,该图12展示的分解图是入光侧位于下方,出光侧位于上方时的结构图。在座体414和基座413之间设置多个滚珠424,当防抖驱动结构带动座体414和载体415相对基座413沿着与光轴垂直的XY平面移动时,座体414可以沿着多个滚珠424滑动。As shown in Figure 12, an exploded view of the base 413 and the base 414 is shown. This exploded view shows the structure with the light-entering side at the bottom and the light-emitting side at the top. Multiple ball bearings 424 are positioned between the base 414 and the base 413. When the anti-shake drive structure drives the base 414 and the carrier 415 to move relative to the base 413 along an XY plane perpendicular to the optical axis, the base 414 can slide along the multiple ball bearings 424.

可以理解为:如图12,在基座413与座体414相对的两个表面之间设置多个滚珠424。It can be understood that, as shown in FIG12 , a plurality of balls 424 are provided between two opposing surfaces of the base 413 and the seat body 414 .

通过在基座413和座体414之间设置多个滚珠424,可以降低座体414移动过程中的摩擦系数,防抖驱动结构的行程控制精度更高,可以降低镜头的抖动量,提升拍摄效果。By arranging multiple balls 424 between the base 413 and the seat body 414, the friction coefficient during the movement of the seat body 414 can be reduced, the stroke control accuracy of the anti-shake drive structure is higher, the shake amount of the lens can be reduced, and the shooting effect can be improved.

本申请示例的多个滚珠具有多种设置方式,比如,在图13示例中,可以在座体414上设置镶嵌槽425,滚珠设置在镶嵌槽425内,且可以在镶嵌槽425内滚动。再比如,也可以在基座413的朝向座体414的表面设置镶嵌槽,滚珠位于该镶嵌槽内。The multiple balls in the examples of this application can be arranged in various ways. For example, in the example of Figure 13, a mounting groove 425 can be provided on the base 414, and the balls are arranged in the mounting groove 425 and can roll in the mounting groove 425. For another example, a mounting groove can be provided on the surface of the base 413 facing the base 414, and the balls are located in the mounting groove.

如图13,该示例的镶嵌槽425设置在座体414上,位于镶嵌槽425内的滚珠424的部分凸出于镶嵌槽425,滚珠424的凸出于镶嵌槽425的部分与基座413接触。As shown in FIG13 , the inlay groove 425 of this example is provided on the seat body 414 , the portion of the ball 424 located in the inlay groove 425 protrudes from the inlay groove 425 , and the portion of the ball 424 protruding from the inlay groove 425 contacts the base 413 .

在执行光学防抖过程中,为了提升座体414相对基座413移动的稳定性,如图13,包括多组滚珠,每组滚珠包括多个滚珠,多组滚珠可以沿着座体414的周向间隔布设,这样可以使得座体414平稳的移动。During the optical image stabilization process, in order to improve the stability of the movement of the seat 414 relative to the base 413, as shown in Figure 13, multiple groups of balls are included, each group of balls includes multiple balls, and the multiple groups of balls can be arranged at intervals along the circumference of the seat 414, so that the seat 414 can move smoothly.

示例的,在图13,包括第一组滚珠424A、第二组滚珠424B和第三组滚珠424C,第一组滚珠424A、第二组滚珠424B和第三组滚珠424C沿着座体414的周向间隔布设。For example, in FIG. 13 , a first group of balls 424A, a second group of balls 424B and a third group of balls 424C are included. The first group of balls 424A, the second group of balls 424B and the third group of balls 424C are spaced apart along the circumference of the seat body 414 .

如图13,第一组滚珠424A、第二组滚珠424B和第三组滚珠424C的连接可以呈三角形,比如,可以呈正三角形,利用三角形的稳定性,可以进一步的提升座体414移动的平稳度。As shown in FIG13 , the connection between the first group of balls 424A, the second group of balls 424B and the third group of balls 424C can be in the form of a triangle, for example, an equilateral triangle. By utilizing the stability of the triangle, the smoothness of the movement of the seat body 414 can be further improved.

在一些可以实现的结构中,每组滚珠的数量可以是一样的,也可以是不一样的。In some feasible structures, the number of balls in each group can be the same or different.

每组滚珠中的多个滚珠的布设方式可以是一样的,也可以是不一样的。The arrangement of the multiple balls in each ball group can be the same or different.

本申请示例中,座体414相对基座413移动时,为了降低座体414在自身重力作用下,发生倾斜的风险。如图14,该图14展示的分解图是入光侧位于下方,出光侧位于上方时的结构图,该示例中,还可以在基座413和座体414之间设置磁吸结构426。可以理解为:如图14,在基座413与座体414相对的两个表面之间设置磁吸结构426。In this example, when the seat 414 moves relative to the base 413, in order to reduce the risk of the seat 414 tilting under its own weight, as shown in Figure 14, the exploded view shown in Figure 14 is a structural diagram with the light-incoming side at the bottom and the light-emitting side at the top. In this example, a magnetic structure 426 can also be provided between the base 413 and the seat 414. This can be understood as follows: as shown in Figure 14, the magnetic structure 426 is provided between the two opposing surfaces of the base 413 and the seat 414.

当防抖驱动结构带动座体414沿着多个滚珠在XY平面内滑动时,磁吸结构426在基座413和座体414之间产生磁吸力F,利用该磁吸力F,可以促使移动过程中的座体414具有朝向基座413的吸引力,如此,可以降低移动的座体414出现倾斜的几率。When the anti-shake drive structure drives the seat 414 to slide along the multiple ball bearings in the XY plane, the magnetic structure 426 generates a magnetic force F between the base 413 and the seat 414. By utilizing this magnetic force F, the seat 414 can be urged to have an attractive force toward the base 413 during the movement, thereby reducing the probability of the moving seat 414 tilting.

在一些示例中,如图15,磁吸结构426可以包括磁吸片426A和磁石426B,磁吸片426A和磁石426B的一者设置在基座413上,另一者设置在座体414上。例如,在图15中,可以将磁石426B在设置基座413上,磁吸片426A设置在座体414上。In some examples, as shown in FIG15 , the magnetic structure 426 may include a magnetic sheet 426A and a magnet 426B, with one of the magnetic sheet 426A and the magnet 426B being disposed on the base 413 and the other being disposed on the base 414. For example, in FIG15 , the magnet 426B may be disposed on the base 413 and the magnetic sheet 426A disposed on the base 414.

磁吸片426A和磁石426B之间具有间隙。利用磁吸片426A和磁石426B之间的吸引力,促使座体414平稳的在XY平面内移动。There is a gap between the magnetic sheet 426A and the magnet 426B. The attraction between the magnetic sheet 426A and the magnet 426B is used to enable the base 414 to move smoothly in the XY plane.

为了减小磁石和磁吸片所占据的面积,比如,如图15,可以在基座413内设置安置槽,磁石426B设置在该安置槽内。In order to reduce the area occupied by the magnet and the magnetic sheet, for example, as shown in FIG15 , a placement groove may be provided in the base 413 , and the magnet 426B may be provided in the placement groove.

在另外一些示例中,也可以在座体414内设置安装槽,将磁吸片426A设置在座体的安置槽内,从而,减小磁吸片426A和磁石426B所占据的空间,进而减小整个摄像头马达的厚度尺寸。In other examples, a mounting groove may be provided in the base 414, and the magnetic sheet 426A may be provided in the mounting groove of the base, thereby reducing the space occupied by the magnetic sheet 426A and the magnet 426B, and further reducing the thickness of the entire camera motor.

磁吸结构426可以设置多组,多组磁吸结构426沿着座体414的周向间隔布设。示例的,多组磁吸结构可以关于镜头的光轴O1-O2对称布设。The magnetic structures 426 may be provided in multiple groups, and the multiple groups of magnetic structures 426 are arranged at intervals along the circumference of the base 414. For example, the multiple groups of magnetic structures may be arranged symmetrically about the optical axis O1-O2 of the lens.

在一些结构中,具有多组滚珠和多组磁吸结构时,如图16,可以在相邻两组滚珠424之间设置一组或者多组磁吸结构426。多组滚珠和多组磁吸结构可以沿着座体414的周向呈交替排布。这样,可以进一步提升座体移动的平稳性,进一步弱化抖动,优化拍摄画面质量。In some configurations, when multiple sets of balls and magnetic structures are present, as shown in Figure 16 , one or more sets of magnetic structures 426 can be positioned between two adjacent sets of balls 424. These sets of balls and magnetic structures can be arranged alternately along the circumference of the base 414. This can further enhance the smoothness of the base's movement, reduce vibration, and optimize image quality.

见图17和图18,图17和图18从不同角度展示摄像头驱动马达的结构。本申请示例中,摄像头驱动马达还可以包括第一弹簧臂427,第一弹簧臂427的一部分与座体414连接,另一部分与基座413连接。17 and 18 , which illustrate the structure of the camera drive motor from different angles. In this example, the camera drive motor may further include a first spring arm 427 , a portion of which is connected to the seat 414 and another portion of which is connected to the base 413 .

在一些示例中,如图19,图19示例性的展示了第一弹簧臂427的一种结构。该第一弹簧臂427可以呈L形结构。第一弹簧臂427包括第一节4271和第二节4273,以及连接第一节4271和第二节4273的连接部4272。In some examples, as shown in FIG19 , FIG19 exemplarily illustrates a structure of the first spring arm 427. The first spring arm 427 may be L-shaped. The first spring arm 427 includes a first section 4271, a second section 4273, and a connecting portion 4272 connecting the first section 4271 and the second section 4273.

继续见图19,第一节4271远离连接部4272的端部,以及第二节4273远离连接部4272的端部,与可以移动的座体414连接,可以被称为活动端427A,连接部4272与基座413连接,可以被称为固定端427B。Continuing to refer to Figure 19, the end of the first section 4271 away from the connecting portion 4272 and the end of the second section 4273 away from the connecting portion 4272 are connected to the movable seat body 414 and can be called the movable end 427A. The connecting portion 4272 is connected to the base 413 and can be called the fixed end 427B.

在一些安装方式中,第一弹簧臂427可以设置在基座413和座体414相对的两个表面之间。In some installation methods, the first spring arm 427 can be disposed between two opposing surfaces of the base 413 and the seat body 414 .

在另外一些安装方式中,如图20,第一弹簧臂427可以设置在座体414的远离基座413的一侧。In some other installation methods, as shown in FIG. 20 , the first spring arm 427 may be disposed on a side of the seat body 414 away from the base 413 .

由于第一弹簧臂427与基座413固定连接,如图20,可以在基座413的边缘设置凸台428,凸台428朝座体414方向延伸,第一弹簧臂427的连接部4272与凸台428固定连接,以使得第一弹簧臂427与基座413固定连接。Since the first spring arm 427 is fixedly connected to the base 413, as shown in FIG20 , a boss 428 can be provided on the edge of the base 413. Extending toward the seat body 414 , the connecting portion 4272 of the first spring arm 427 is fixedly connected to the boss 428 , so that the first spring arm 427 is fixedly connected to the base 413 .

在本申请实施例中,SMA线通电驱动载体415、座体414和镜头移动,实现防抖的过程中,第一弹簧臂427可以平衡和缓冲座体414的受力,使得座体414的移动更加平稳。In the embodiment of the present application, the SMA wire is energized to drive the carrier 415, the base 414 and the lens to move. During the anti-shake process, the first spring arm 427 can balance and buffer the force on the base 414, making the movement of the base 414 more stable.

另外,第一弹簧臂还能够在SMA线断电时,通过在SMA线通电驱动座体移动的过程中产生形变所形成的弹力,驱动座体414和承载有镜头的载体415移动至初始位置。In addition, when the SMA wire is powered off, the first spring arm can generate elastic force by deforming during the process of driving the base to move when the SMA wire is powered on, thereby driving the base 414 and the carrier 415 carrying the lens to move to the initial position.

在一些示例中,返回至图17和图18,可以包括两个第一弹簧臂427,两个第一弹簧臂可以关于镜头的O1-O2对称布设,对称布设的两个第一弹簧臂在座体414发生移动时,可以产生相同的形变量。In some examples, returning to Figures 17 and 18, two first spring arms 427 can be included. The two first spring arms can be symmetrically arranged about O1-O2 of the lens. The two symmetrically arranged first spring arms can generate the same deformation when the base 414 moves.

见图17所示,两个第一弹簧臂可以分别被称为弹簧臂A和弹簧臂B,弹簧臂A的第一节4271平行于座体414的第一侧边,弹簧臂A的第二节4273平行于座体414的第二侧边;弹簧臂B的第一节4271平行于座体414的第三侧边,弹簧臂B的第二节4273平行于座体的第四侧边,其中,第一侧边与第三侧边相对,第二侧边与第四侧边相对。As shown in Figure 17, the two first spring arms can be respectively referred to as spring arm A and spring arm B, the first section 4271 of spring arm A is parallel to the first side of the base body 414, and the second section 4273 of spring arm A is parallel to the second side of the base body 414; the first section 4271 of spring arm B is parallel to the third side of the base body 414, and the second section 4273 of spring arm B is parallel to the fourth side of the base body, wherein the first side is opposite to the third side, and the second side is opposite to the fourth side.

可以理解为:弹簧臂A的第一节与弹簧臂B的第一节相对设置,弹簧臂A的第一节的形状与弹簧臂B的第一节形状可以相同;弹簧臂A的第二节与弹簧臂B的第二节相对设置,弹簧臂A的第二节的形状与弹簧臂B的第二节形状可以相同;使得两个弹簧臂可以关于镜头的光轴对称布设,进而使得弹性力对称。It can be understood that: the first section of spring arm A is arranged opposite to the first section of spring arm B, and the shape of the first section of spring arm A can be the same as the shape of the first section of spring arm B; the second section of spring arm A is arranged opposite to the second section of spring arm B, and the shape of the second section of spring arm A can be the same as the shape of the second section of spring arm B; so that the two spring arms can be arranged symmetrically about the optical axis of the lens, thereby making the elastic force symmetrical.

本申请实施例中,如图21和图22,图22是自图21的下表面看去的视图。用于减小座体414移动摩擦系数的滚珠424,和用于削弱座体414移动倾斜的磁吸结构426均设置在基座413与座体414相对的两个表面之间,可以理解为设置在基座413的上表面,定卡爪4211和SMA线4212设置在基座413的下表面,第一弹簧臂427设置在座体414背离基座413的一侧。也就是说,防抖驱动结构421、滚珠424和磁吸结构426,以及第一弹簧臂427未集中设置,而是分布设置在不同的位置处。这样,可以充分利用不同位置的空间,也可以避免多个结构件发生干涉现象。In the embodiment of the present application, as shown in Figures 21 and 22, Figure 22 is a view from the bottom surface of Figure 21. The ball 424 for reducing the friction coefficient of the seat 414 and the magnetic structure 426 for reducing the tilt of the seat 414 are both arranged between the two opposite surfaces of the base 413 and the seat 414. It can be understood that they are arranged on the upper surface of the base 413, the fixed claw 4211 and the SMA wire 4212 are arranged on the lower surface of the base 413, and the first spring arm 427 is arranged on the side of the seat 414 away from the base 413. In other words, the anti-shake drive structure 421, the ball 424 and the magnetic structure 426, as well as the first spring arm 427 are not arranged in a centralized manner, but are distributed in different positions. In this way, the space at different positions can be fully utilized, and interference between multiple structural components can be avoided.

如图23所示,图23简易示出了座体414、载体415和镜头40的位置关系。由于摄像头驱动马达在其厚度方向(如图23的Z方向)上具有尺寸,随着终端设备小型化、轻薄化的发展,需要摄像头驱动马达的厚度尺寸越来越小,或者,当摄像头驱动马达不工作时,即摄像头驱动马达不执行自动对焦或者防抖补偿任一项功能时,摄像头驱动马达的厚度尺寸较小,当摄像头驱动马达工作时,可以调整至预设的厚度尺寸,保证自动对焦和防抖补偿的正常使用。As shown in FIG23 , FIG23 simply illustrates the positional relationship between the base 414, the carrier 415, and the lens 40. Since the camera drive motor has a dimension in its thickness direction (such as the Z direction in FIG23 ), as terminal devices become smaller and thinner, the thickness of the camera drive motor needs to be smaller and smaller. Alternatively, when the camera drive motor is not working, that is, when the camera drive motor is not performing any of the autofocus or anti-shake compensation functions, the thickness of the camera drive motor is relatively small. When the camera drive motor is working, the thickness can be adjusted to a preset dimension to ensure the normal use of autofocus and anti-shake compensation.

在一些实施例中,电子设备可以包括预压驱动结构,摄像头驱动马达不工作时,如图23的(a),预压驱动结构可以给载体415和镜头40施加朝向基座的预压力F,以压缩整个摄像头驱动马达的厚度尺寸,比如,可以将载体415和镜头40压至第一位置,如图23的(b),当摄像头驱动马达需要工作时,载体415和镜头40可以移动至第二位置,第一位置至第二位置的指向平行于镜头的光轴O1-O2,第一位置相比第二位置靠近座体414。In some embodiments, the electronic device may include a pre-stress drive structure. When the camera drive motor is not working, as shown in (a) of Figure 23, the pre-stress drive structure can apply a pre-stress F toward the base to the carrier 415 and the lens 40 to compress the thickness of the entire camera drive motor. For example, the carrier 415 and the lens 40 can be pressed to a first position, as shown in (b) of Figure 23. When the camera drive motor needs to work, the carrier 415 and the lens 40 can be moved to a second position. The direction from the first position to the second position is parallel to the optical axis O1-O2 of the lens, and the first position is closer to the base 414 than the second position.

这样,当载体415和镜头40被压缩至第一位置时,就可以使得整个摄像头驱动马达的厚度尺寸被压缩,载体415和镜头40移动至第二位置时,保障自动对焦和防抖补偿的正常使用。In this way, when the carrier 415 and the lens 40 are compressed to the first position, the thickness of the entire camera drive motor can be compressed. When the carrier 415 and the lens 40 move to the second position, the normal use of autofocus and anti-shake compensation is guaranteed.

在一些摄像头驱动结构中,如图23的(a)和(b),第一位置和第二位置之间的距离X1可以达到500μm以上,这样,可以明显的压缩摄像头驱动马达在不工作时的厚度尺寸。In some camera drive structures, such as (a) and (b) of FIG. 23 , the distance X1 between the first position and the second position can be greater than 500 μm, which can significantly reduce the thickness of the camera drive motor when not working.

摄像头驱动马达需要工作时,电子设备的预压驱动结构对载体415和镜头40的预压力F被撤除。为了使得载体415和镜头40自第一位置移动至第二位置,在本申请示例中,如图23,可以在摄像头驱动马达中设置弹性件50,弹性件50用于给载体415和镜头40自第一位置移动至第二位置的弹力f。When the camera drive motor needs to operate, the preload force F applied by the preload drive structure of the electronic device to the carrier 415 and lens 40 is removed. To enable the carrier 415 and lens 40 to move from the first position to the second position, an elastic member 50 may be provided in the camera drive motor, as shown in FIG23 . The elastic member 50 is used to apply the elastic force f to the carrier 415 and lens 40 to move from the first position to the second position.

当需要执行自动对焦时,如图23的(b)和(c),承载有镜头40的载体415在对焦驱动结构的带动下,可以在第二位置和第三位置之间移动,实现对焦,其中,第二位置处于第一位置和第三位置之间。When autofocus needs to be performed, as shown in (b) and (c) of Figure 23, the carrier 415 carrying the lens 40 can be moved between the second position and the third position under the drive of the focus drive structure to achieve focusing, wherein the second position is between the first position and the third position.

载体415和镜头40在第二位置和第三位置之间移动时,载体415与弹性件50分离,弹性件50不会对载体415和镜头40产生弹力。When the carrier 415 and the lens 40 move between the second position and the third position, the carrier 415 is separated from the elastic member 50 , and the elastic member 50 does not generate elastic force on the carrier 415 and the lens 40 .

如图24和图25所示,图24展示了弹性件50的其中一种安装方式,图25是图24的分解图。该示例中,弹性件50可以设置在载体415的下方,当载体415和镜头40位于第一位置时,载体415与弹性件50接触,弹性件50发生形变,产生自第一位置指向第二位置的弹力。在弹性件50的弹力作用下,载体415和镜头40可以朝着背离基座的方向自第一位置移动至第二位置。As shown in Figures 24 and 25, Figure 24 illustrates one method for installing the elastic member 50, while Figure 25 is an exploded view of Figure 24. In this example, the elastic member 50 can be positioned below the carrier 415. When the carrier 415 and the lens 40 are in the first position, the carrier 415 contacts the elastic member 50, causing the elastic member 50 to deform, generating an elastic force directed from the first position to the second position. Under the elastic force of the elastic member 50, the carrier 415 and the lens 40 can move from the first position to the second position, away from the base.

在一些示例中,如图26,弹性件50包括第一支耳501和第二支耳502,以及连接在第一支耳501和第二支耳502之间的弹性段503。In some examples, as shown in FIG. 26 , the elastic member 50 includes a first lug 501 , a second lug 502 , and an elastic segment 503 connected between the first lug 501 and the second lug 502 .

如图24,第一支耳501和第二支耳502可以固定在座体414上,弹性段503可以延伸至载体415的下方。As shown in FIG. 24 , the first ear 501 and the second ear 502 can be fixed on the base 414 , and the elastic section 503 can extend to the bottom of the carrier 415 .

比如,见图25,可以在载体415上设置凸起51,在预压驱动结构对载体415和镜头40的预压力F作用下,承载有镜头40的载体415沿着光轴O1-O2移动至第一位置时,弹性件50的弹性段503会与凸起51接触,并使得弹性段503发生变形,产生自第一位置指向第二位置的弹力。当预压驱动结构对载体415和镜头40的预压力F作用下撤除后,弹性段503的弹力可以使得载体415和镜头40由第一位置移动至第二位置。For example, as shown in FIG25 , a protrusion 51 can be provided on the carrier 415. When the carrier 415, carrying the lens 40, moves along the optical axis O1-O2 to a first position under the action of a preload F exerted by the preload drive structure on the carrier 415 and the lens 40, the elastic segment 503 of the elastic member 50 contacts the protrusion 51, causing the elastic segment 503 to deform, generating an elastic force directed from the first position to the second position. When the preload drive structure removes the preload F exerted on the carrier 415 and the lens 40, the elastic force of the elastic segment 503 causes the carrier 415 and the lens 40 to move from the first position to the second position.

如图24和图25,在一些示例中,可以包括多个弹性件50,多个弹性件50可以关于光轴O1-O2对称布设,以使得弹性力对称,载体415和镜头40在该对称弹力作用下稳定的移动。As shown in FIG. 24 and FIG. 25 , in some examples, a plurality of elastic members 50 may be included. The plurality of elastic members 50 may be symmetrically arranged about the optical axis O1 - O2 so that the elastic force is symmetrical, and the carrier 415 and the lens 40 move stably under the action of the symmetrical elastic force.

在一些摄像头驱动结构中,返回至图23,如图23的(b)和(c),该摄像头模组在自动对焦时,第二位置和第三位置之间的距离X2可以达到1000μm以上。除外,第一位置和第二位置之间的距离X1可以达到500μm以上,这样,载体和镜头组件在第一位置和所述第三位置之间移动时,行程(X1+X2)达到1500μm以上。In some camera drive structures, returning to FIG. 23 , as shown in FIG. 23 (b) and (c), when the camera module is autofocusing, the distance X2 between the second position and the third position can be greater than 1000 μm. Furthermore, the distance X1 between the first position and the second position can be greater than 500 μm. Thus, when the carrier and lens assembly move between the first position and the third position, the travel (X1 + X2) reaches greater than 1500 μm.

可以理解为,本申请示例中,承载有镜头40的载体415的行程不仅包括在弹性件50弹力作用下的缓冲行程,还包括在对焦驱动结构驱动力下的对焦行程。相比仅包含对焦行程,本申请示例的镜头40和载体415的行程较大。It can be understood that in this example, the travel of the carrier 415 carrying the lens 40 includes not only the buffering travel under the elastic force of the elastic member 50, but also the focusing travel under the driving force of the focus drive structure. Compared to the travel including only the focusing travel, the travel of the lens 40 and carrier 415 in this example is greater.

承载有镜头40的载体415在较大的行程时,为了提升移动的稳定性,如图27和图28所示,摄像头驱动马达还可以包括滑杆53,滑杆53的轴向平行于镜头的光轴O1-O2方向,滑杆53相对于座体414固定,载体415与滑杆53滑动连接。In order to improve the stability of movement when the carrier 415 carrying the lens 40 has a larger stroke, as shown in Figures 27 and 28, the camera drive motor can also include a slide rod 53, the axial direction of the slide rod 53 is parallel to the optical axis O1-O2 direction of the lens, the slide rod 53 is fixed relative to the base body 414, and the carrier 415 is slidably connected to the slide rod 53.

载体415和镜头40在图23所示的第一位置和第三位置之间移动时,该滑杆53作为指引导向结构,载体415会沿着滑杆53的轴向滑动,保障载体415和镜头40的移动轨迹基本为直线运动。When the carrier 415 and the lens 40 move between the first position and the third position shown in Figure 23, the slide bar 53 serves as a guiding structure, and the carrier 415 slides along the axial direction of the slide bar 53 to ensure that the movement trajectory of the carrier 415 and the lens 40 is basically a linear motion.

在图29中,示例性的给出了滑杆53的其中一种设置方式。沿着平行于镜头的光轴O1-O2方向,在载体上开设导向槽55,滑杆53滑动设置在该导向槽55内。Figure 29 exemplarily shows one arrangement of the slide bar 53. A guide groove 55 is provided on the carrier along a direction parallel to the optical axis O1-O2 of the lens, and the slide bar 53 is slidably arranged in the guide groove 55.

为了进一步提升滑杆53与导向槽55之间的相对运动速度,在一些实现方式中,可以在导向槽55内设置润滑结构。比如,可以在导向槽55内填充润滑油;再比如,可以在导向槽55的内壁面上形成摩擦系数较小的膜层结构。To further increase the relative movement speed between the slide bar 53 and the guide groove 55, in some implementations, a lubrication structure may be provided in the guide groove 55. For example, the guide groove 55 may be filled with lubricating oil; or, for another example, a film structure with a low friction coefficient may be formed on the inner wall surface of the guide groove 55.

承载有镜头40的载体415在相对座体414移动时,为了提升载体415相对滑杆53滑动的稳定性,可以在该摄像头驱动马达中设置多个滑杆53。比如,在图27和图28示例中,设置滑杆A和滑杆B,滑杆A和滑杆B可以沿着载体415的周向间隔排布,滑杆A和滑杆B设置在相对应的导向槽内。To improve the stability of the carrier 415 sliding relative to the slide bar 53 when the carrier 415 carrying the lens 40 moves relative to the base 414, multiple slide bars 53 can be provided in the camera drive motor. For example, in the examples of Figures 27 and 28, slide bars A and B are provided. Slide bars A and B can be arranged at intervals along the circumference of the carrier 415, and slide bars A and B are disposed in corresponding guide grooves.

在一些示例中,也可以设置更多个滑杆,这些多个滑杆可以沿着载体的周向均匀分布,这些多个滑杆也可以关于镜头的光轴O1-O2对称设置,以使得镜头对焦时,运动更加平稳。In some examples, more slide bars may be provided, and these multiple slide bars may be evenly distributed along the circumference of the carrier. These multiple slide bars may also be symmetrically arranged about the optical axis O1 - O2 of the lens, so that the movement of the lens is smoother when focusing.

在一些结构中,如图28,载体415具有与滑杆53滑动配合的抵接面531,载体415沿着滑杆53的轴向滑动时,滑杆53与抵接面接触。滑杆53与抵接面531抵接,对滑杆53的移动起到定位作用,保障载体415沿着滑杆53的轴向直线移动。In some configurations, as shown in FIG28 , the carrier 415 has an abutment surface 531 that slidably engages the slide bar 53. When the carrier 415 slides axially along the slide bar 53, the slide bar 53 contacts the abutment surface. The abutment between the slide bar 53 and the abutment surface 531 serves to position the slide bar 53 and ensure that the carrier 415 moves linearly along the axial direction of the slide bar 53.

在一些可以实现的结构中,可以包括多个滑杆53和多个弹性件50。多个滑杆53和多个弹性件50可以沿着载体415的周向呈交替排布。即就是,相邻两个滑杆53之间可以设置一个弹性件50,相邻两个弹性件50之间可以设置一个滑杆53。In some possible structures, multiple sliding rods 53 and multiple elastic members 50 may be included. The multiple sliding rods 53 and the multiple elastic members 50 may be arranged alternately along the circumference of the carrier 415. That is, one elastic member 50 may be provided between two adjacent sliding rods 53, and one sliding rod 53 may be provided between two adjacent elastic members 50.

为了进一步使得承载有镜头40的载体415相对座体414沿平行于镜头光轴O1-O2的方向直线移动,本申请实施例中,如图28和图29,还增加了吸引结构54,该吸引结构54可以对滑杆53产生吸引力。这样,当对焦驱动结构驱动载体415和镜头40沿着镜头的光轴O1-O2移动时,载体415在吸引力的吸引下能够沿着滑杆53的轴向直线滑动。To further enable the carrier 415 carrying the lens 40 to move linearly relative to the base 414 in a direction parallel to the lens optical axis O1-O2, an attraction structure 54 is added in the embodiment of the present application, as shown in Figures 28 and 29. This attraction structure 54 can generate an attractive force on the slide bar 53. In this way, when the focus drive structure drives the carrier 415 and the lens 40 to move along the lens optical axis O1-O2, the carrier 415 can slide linearly along the axial direction of the slide bar 53 under the attraction force.

在一些示例中,如图29,吸引结构54可以包括磁体,磁体固定在载体415上,磁体并靠近滑杆53设置,比如,该滑杆53可以为具有磁性的金属结构件,磁体与滑杆之间产生有吸引力f,利用该吸引力f使得载体415在移动过程中,抱紧滑杆53,从而,沿着滑杆53的轴向滑动。或者,滑杆53可以为非磁性的结构件,比如,陶瓷,可以在陶瓷的外壁面上形成具有磁性的材料。In some examples, as shown in FIG29 , the attraction structure 54 may include a magnet fixed to the carrier 415 and disposed near the slide bar 53. For example, the slide bar 53 may be a magnetic metal structure. An attractive force f is generated between the magnet and the slide bar, and the carrier 415 is caused to hold the slide bar 53 tightly during movement, thereby sliding along the axial direction of the slide bar 53. Alternatively, the slide bar 53 may be a non-magnetic structure, such as ceramic, and a magnetic material may be formed on the outer wall of the ceramic.

参阅图29,当采用磁体抱紧滑杆的方式时,可以在载体415的位于滑杆53旁侧的位置处设置安装腔56,将磁体设置在该安装腔56内,例如,磁体可以通过胶层57设置在安装腔56内。Referring to Figure 29, when the magnet is used to hold the slide bar, a mounting cavity 56 can be set at a position next to the slide bar 53 of the carrier 415, and the magnet can be set in the mounting cavity 56. For example, the magnet can be set in the mounting cavity 56 through a glue layer 57.

在一些示例中,如图26,滑杆53靠近对焦驱动单元的线圈和磁石设置,吸引结构54的磁体靠近滑杆53设置,对焦驱动单元的线圈和磁石之间会产生电磁感应,以及,吸引结构54的磁体和滑杆53之间会产生磁吸力。In some examples, as shown in FIG26 , the slide bar 53 is disposed close to the coil and magnet of the focus drive unit, and the magnet of the attraction structure 54 is disposed close to the slide bar. The rod 53 is set, electromagnetic induction is generated between the coil of the focus drive unit and the magnet, and magnetic attraction is generated between the magnet of the attraction structure 54 and the slide rod 53.

为了避免对焦驱动单元的线圈和磁体之间的电磁感应,与吸引结构的磁体和滑杆之间的磁吸力相互影响,如图26,吸引结构54的磁体相比对焦驱动单元,更加靠近滑杆53。这样,可以削弱他们之间的互相干扰。To prevent electromagnetic induction between the coil and magnet of the focus drive unit from interfering with the magnetic attraction between the magnet of the attraction structure and the slide bar, as shown in FIG26 , the magnet of the attraction structure 54 is closer to the slide bar 53 than the focus drive unit. This can reduce the mutual interference between them.

本申请示例中,即使承载有镜头40的载体415具有较大的行程,比如包含上述涉及的缓冲行程,和在对焦驱动结构驱动力下的对焦行程,在滑杆53和吸引结构54的作用下,可以使得承载有镜头40的载体415的运动轨迹基本沿着光轴O1-O2,降低镜头组件在大行程中发生偏移的风险。In the example of the present application, even if the carrier 415 carrying the lens 40 has a large stroke, such as the buffer stroke mentioned above, and the focus stroke under the driving force of the focus drive structure, under the action of the slide rod 53 and the attraction structure 54, the movement trajectory of the carrier 415 carrying the lens 40 can be basically along the optical axis O1-O2, reducing the risk of the lens assembly offset during a large stroke.

本申请示例中,还可以包括位置检测结构,位置检测结构用于检测载体415相对滑杆53滑动的位置。In this example of the present application, a position detection structure may also be included, and the position detection structure is used to detect the position of the carrier 415 sliding relative to the slide bar 53.

示例的,位置检测结构可以采用电磁式传感器(electromagnetic transducer),当承载有镜头的载体415相对于座体414移动对焦时,利用电磁式传感器感应磁通量变化,以转换成输出信号变化,从而确定镜头的位置。For example, the position detection structure can use an electromagnetic sensor (electromagnetic transducer). When the carrier 415 carrying the lens moves relative to the base 414 to focus, the electromagnetic sensor is used to sense the change in magnetic flux and convert it into an output signal change, thereby determining the position of the lens.

在一些示例中,可以在载体415上设置与电磁式传感器相对设置的检测磁体,那么,当装配有镜头和检测磁体的载体415沿着镜头的光轴O1-O2方向移动,电磁式传感器感应检测磁体的磁通量变化,确定镜头位置。In some examples, a detection magnet can be set on the carrier 415 and arranged opposite to the electromagnetic sensor. Then, when the carrier 415 equipped with the lens and the detection magnet moves along the optical axis O1-O2 of the lens, the electromagnetic sensor senses the change in the magnetic flux of the detection magnet and determines the position of the lens.

在一些示例中,位置检测结构中的检测磁体可以与对焦驱动结构中的磁石共用,这样可以简化结构。In some examples, the detection magnet in the position detection structure can be shared with the magnet in the focus drive structure, which can simplify the structure.

请参阅图30,图30为电子设备的内部电路图。在本申请实施例中,电子设备还包括计算控制器。一些实施例中,计算控制器和位置检测结构中的电磁式传感器和可以设置于主板上。当然,电磁式传感器和计算控制器也可以设置于电子设备内的其他结构上,比如设置于通用串行总线(universal serial bus,USB)器件所处的电路板上,图30仅给出了电磁式传感器和计算控制器设置于主板上的示例,这并不能认为是对本申请构成的特殊限制。Please refer to Figure 30, which is an internal circuit diagram of an electronic device. In an embodiment of the present application, the electronic device further includes a computing controller.

Of course, the electromagnetic sensor and the computing controller can also be arranged on other structures within the electronic device, such as on a circuit board where a universal serial bus (USB) device is located. Figure 30 only gives an example of the electromagnetic sensor and the computing controller being arranged on a mainboard, which cannot be considered as a special limitation to the present application.

In some embodiments, the computation controller is a microprocessor. The computation controller is used to receive and process electrical signals containing image information from the camera module. The computation controller is further used to calculate the lens movement amount based on the lens position and control the movement of the camera module lens based on the lens movement amount.

如图31,本申请示例的摄像头驱动马达还可以包括第二弹簧臂58,第二弹簧臂58的一部分与座体414连接,另一部分与载体415连接。该摄像头模组执行自动对焦时,镜头40和载体415以及可变光圈沿着镜头的光轴O1-O2移动时,第二弹簧臂58发生变形,平衡和缓冲可变光圈与镜头组件的受力,使得可变光圈与镜头组件的移动更加平稳。As shown in Figure 31 , the camera drive motor of the present application may further include a second spring arm 58, a portion of which is connected to the base 414, and another portion of which is connected to the carrier 415. When the camera module performs autofocus, as the lens 40, the carrier 415, and the iris diaphragm move along the optical axis O1-O2 of the lens, the second spring arm 58 deforms to balance and buffer the forces acting on the iris diaphragm and the lens assembly, thereby making their movement smoother.

在一些示例中,如图31,可以包括多个第二弹簧臂58,多个第二弹簧臂58沿着载体415的周向间隔排布。比如,多个第二弹簧臂可以关于镜头的光轴O1-O2对称布设,那么,镜头、可变光圈和载体沿着镜头的光轴O1-O2移动时,多个第二弹簧臂可以产生相同的形变量,提供对称的弹力。In some examples, as shown in FIG31 , multiple second spring arms 58 may be included, and the multiple second spring arms 58 may be arranged at intervals along the circumference of the carrier 415. For example, the multiple second spring arms may be arranged symmetrically about the optical axis O1-O2 of the lens. Then, when the lens, the iris diaphragm, and the carrier move along the optical axis O1-O2 of the lens, the multiple second spring arms may generate the same amount of deformation, thereby providing symmetrical elastic forces.

图32是本申请实施例给出的一种第二弹簧臂58的实现结构。第二弹簧臂58包括第一枝臂581和第二枝臂582,第一枝臂581和第二枝臂582可以相互靠近设置,每一个枝臂的一端与载体415连接,另一端与座体414连接。FIG32 illustrates an embodiment of the present invention showing a second spring arm 58. The second spring arm 58 includes a first branch arm 581 and a second branch arm 582. The first branch arm 581 and the second branch arm 582 can be positioned adjacent to each other, with one end of each branch arm connected to the carrier 415 and the other end connected to the base 414.

通过如图32设置的多个分离的枝臂,可以进一步平衡和缓冲可变光圈与镜头组件的受力,使得可变光圈与镜头组件的移动更加平稳。By providing a plurality of separate arms as shown in FIG32 , the forces acting on the iris diaphragm and the lens assembly can be further balanced and buffered, making the movement of the iris diaphragm and the lens assembly smoother.

如图33和图34所示,图34是图33中座体414和载体415的分解图。本申请示例的座体414可以包括主体部414A和延伸部414B,延伸部414B设置在主体部414A的靠近基座的一侧,延伸部414B沿着主体部414A外缘周向朝远离主体部414A方向延伸,这样,座体的主体部414A和延伸部414B之间可以形成如图33和图34所示的台阶。As shown in Figures 33 and 34, Figure 34 is an exploded view of the base 414 and the carrier 415 in Figure 33. The base 414 of the present application example may include a main body 414A and an extension 414B. The extension 414B is provided on a side of the main body 414A close to the base. The extension 414B extends along the outer circumference of the main body 414A in a direction away from the main body 414A. In this way, a step may be formed between the main body 414A and the extension 414B of the base, as shown in Figures 33 and 34.

利用本申请示例的具有台阶的座体,可以在主体部414A的外围形成空间,可以利用该空间布设摄像头模组中的其他结构件。By using the seat with steps in the example of this application, a space can be formed on the periphery of the main body 414A, and other structural components in the camera module can be arranged in the space.

在一些结构中,主体部414A和延伸部414B可以是一体成型结构件。In some constructions, the main body portion 414A and the extension portion 414B can be a unitary structure.

The circuit structure on the seat 414 and the circuit structure on the base 413 are electrically connected to the circuit board of the camera module, so that the variable aperture drive structure, focus drive structure, anti-shake drive structure, etc. form a drive path with the circuit board.

The electrical connection structure may include a second spring arm 58, which includes a first end 58A and a second end 58B. The second end 58B of the second spring arm 58 may be electrically connected to the drive structure of the iris diaphragm. For example, when the drive structure of the iris diaphragm includes a coil and a magnet, the second end 58B of the second spring arm 58 may be electrically connected to the coil of the iris diaphragm.

在图36示例中,包括两个第二弹簧臂58,每个第二弹簧臂58包括两个枝臂,每一个枝臂具有一个第二端58B,这样,两个第二弹簧臂58具有与可变光圈的线圈电连接的四个第二端58B。In the example of FIG. 36 , two second spring arms 58 are included. Each second spring arm 58 includes two branches, and each branch arm has a second end 58B. Thus, the two second spring arms 58 have four second ends 58B electrically connected to the coil of the variable aperture.

可变光圈的驱动结构包括四个线圈时,四个第二端58B中的两个连接四个线圈中的其中两个线圈,四个第二端58B中的另外两个连接四个线圈中的剩余两个线圈。When the driving structure of the variable aperture includes four coils, two of the four second ends 58B are connected to two of the four coils, and the other two of the four second ends 58B are connected to the remaining two of the four coils.

在一些示例中,如图35和图36,可以在座体414上设置导线等导电结构与柔性电路板(flexible printed circuit,FPC)61电连接。In some examples, as shown in Figures 35 and 36, a conductive structure such as a wire can be provided on the seat 414 to electrically connect to the flexible printed circuit (FPC) 61.

导电结构具有多种实现方式。比如,可以通过电镀方式形成导电引线;再比如,可以通过嵌埋注塑成型(Insert Molding)埋设金属的方式形成导电引线。Conductive structures can be implemented in a variety of ways. For example, conductive leads can be formed by electroplating. Another example is the use of insert molding to embed metal.

其中,见图35和图36,第二弹簧臂58的第一端58A可以通过设置在座体414上的第一导电引线62与柔性电路板FPC61电连接。这样,可以通过第二弹簧臂58,以及设置在座体414上的第一导电引线62,将可变光圈与柔性电路板FPC61电连接,柔性电路板FPC61电连接与摄像头模组的电路板电连接,这样,摄像头模组的电路板与可变光圈的线圈形成驱动通路。As shown in Figures 35 and 36 , the first end 58A of the second spring arm 58 can be electrically connected to the flexible printed circuit board (FPC) 61 via a first conductive lead 62 provided on the base 414. Thus, the variable aperture can be electrically connected to the flexible printed circuit board (FPC) 61 via the second spring arm 58 and the first conductive lead 62 provided on the base 414. The flexible printed circuit board (FPC) 61 is then electrically connected to the camera module's circuit board, thus forming a drive path between the camera module's circuit board and the coil of the variable aperture.

可以理解为,本申请示例的第二弹簧臂58不仅具有缓冲和平衡镜头移动稳定性的作用,还具有电连接作用。It can be understood that the second spring arm 58 in the example of the present application not only has the function of buffering and balancing the stability of lens movement, but also has the function of electrical connection.

在一些可以实现的结构中,见图35和图36,对焦驱动单元中的线圈可以通过设置在座体414上的导电结构与柔性电路板FPC电连接,比如,通过嵌埋注塑成型(Insert Molding)埋设金属的方式形成的第一导电引线62,将对焦驱动结构中的线圈与柔性电路板FPC电连接,柔性电路板FPC电连接与摄像头模组的电路板电连接,这样,摄像头模组的电路板与对焦驱动结构中的线圈形成驱动通路。In some feasible structures, see Figures 35 and 36, the coil in the focus drive unit can be electrically connected to the flexible circuit board FPC through a conductive structure provided on the base 414. For example, a first conductive lead 62 is formed by embedding metal by insert molding, which electrically connects the coil in the focus drive structure to the flexible circuit board FPC, and the flexible circuit board FPC is electrically connected to the circuit board of the camera module. In this way, the circuit board of the camera module and the coil in the focus drive structure form a driving path.

To form a drive path between the SMA drive assembly and the camera module's circuit board, as shown in FIG37 , FIG37 illustrates the electrical connection structure of the SMA drive assembly. The SMA drive assembly may include multiple connection terminals.
