对于带SIM卡的手表，现有技术中SIM卡座可以采用抽屉式卡座，但是抽屉式卡座的防水效果不好。而且SIM卡座和无线充电线圈通常放在手表底部，两者会产生结构冲突。将SIM卡座放在线圈中间，由于SIM卡座或手表PCB(Printed Circuit Board，印制电路板)大面积是金属，会导致卡座发热量大，无线充电效率降低。For watches with SIM cards, the SIM card holder in the prior art can adopt a drawer-type holder, but the waterproof effect of the drawer-type holder is not good. Moreover, the SIM card holder and the wireless charging coil are usually placed at the bottom of the watch, and there will be structural conflicts between the two. Put the SIM card holder in the middle of the coil. Since the SIM card holder or the watch PCB (Printed Circuit Board, printed circuit board) is mostly metal, it will cause a lot of heat in the card holder and reduce the wireless charging efficiency.

下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

实施例Example

图1为本发明实施例提供的一种带无线充电装置的手表的俯视结构示意图，所述手表可以通过无线充电装置实现无线充电的功能。本发明实施例提供的带无线充电装置的手表包括：PCB板110、外壳120、SIM卡座130、无线充电接收线圈140和设置有铁氧体的SIM卡盖150。FIG. 1 is a schematic top view of a watch with a wireless charging device provided by an embodiment of the present invention, and the watch can realize the wireless charging function through the wireless charging device. A watch with a wireless charging device provided by an embodiment of the present invention includes: aPCB board 110 , acasing 120 , aSIM card holder 130 , a wirelesscharging receiving coil 140 and aSIM card cover 150 provided with ferrite.

其中，外壳120开设有安装口，SIM卡座130的卡槽与所述安装口以及无线充电接收线圈140的中心开口同轴设置，SIM卡座130的底面安装于PCB板110，SIM卡盖150与所述安装口可拆卸连接。Wherein, thehousing 120 is provided with an installation opening, the card slot of theSIM card holder 130 is coaxially arranged with the installation opening and the central opening of the wirelesscharging receiving coil 140, the bottom surface of theSIM card holder 130 is installed on thePCB board 110, and theSIM card cover 150 It is detachably connected with the installation port.

具体的，无线充电接收线圈在充电的过程中需要至少一个接收线圈和至少一个发射线圈。发射线圈设置在充电基站中，接收线圈设置在待充电设备中，通过电耦合技术进行电能的传输。在本实施例中，待充电设备为手表，充电基站可以放置在距离待充电手表预设距离的范围内。手表的外壳120开设有安装口，SIM卡座130的卡槽用来放置SIM卡。SIM卡座130的卡槽与所述安装口以及无线充电接收线圈140的中心开口同轴设置，有利于将SIM卡座130固定。SIM卡座130的底面安装于PCB板110，其中，PCB板110上设置有各个元器件焊接或贴片组成的电路，该电路可以作为无线充电过程中的储能部件，以及为手表运行时提供电能。Specifically, the wireless charging receiving coil requires at least one receiving coil and at least one transmitting coil during charging. The transmitting coil is set in the charging base station, the receiving coil is set in the device to be charged, and the electric energy is transmitted through the electric coupling technology. In this embodiment, the device to be charged is a watch, and the charging base station can be placed within a preset distance from the watch to be charged. Thecasing 120 of the watch is provided with an installation opening, and the card slot of theSIM card holder 130 is used to place the SIM card. The card slot of theSIM card holder 130 is arranged coaxially with the installation port and the central opening of the wirelesscharging receiving coil 140 , which is beneficial to fix theSIM card holder 130 . The bottom surface of theSIM card holder 130 is installed on thePCB board 110, wherein, thePCB board 110 is provided with a circuit composed of various components welded or pasted, and the circuit can be used as an energy storage component in the wireless charging process, and provide a watch when it is running. electrical energy.

可选的，SIM卡座130和无线充电接收线圈140均放在手表的底部，这样可以将手表的顶部留出足够的空间设置手表表盘屏幕；而且，手表的底部相对手表的侧面面积较大，这样可以放置较大的无线充电接收线圈140，较大的无线充电接收线圈140会产生更高的充电效率。Optionally, both theSIM card holder 130 and the wirelesscharging receiving coil 140 are placed at the bottom of the watch, so that enough space can be left on the top of the watch to set the watch dial screen; moreover, the bottom of the watch has a larger area relative to the side of the watch, In this way, a larger wirelesscharging receiving coil 140 can be placed, and a larger wirelesscharging receiving coil 140 will produce higher charging efficiency.

SIM卡盖150与所述安装口可拆卸连接，其中，SIM卡盖150中含有铁氧体。由于无线充电过程中，发射线圈和接收线圈在电能传输的过程中，会产生磁力线外泄问题，铁氧体起到了磁屏蔽的作用。而SIM卡座130和PCB板110上大部分是金属，SIM卡盖150上设置有铁氧体，使得金属不会产生涡流而发热和影响效率，也不会使磁力线外泄。TheSIM card cover 150 is detachably connected to the installation port, wherein theSIM card cover 150 contains ferrite. During the wireless charging process, the transmitting coil and the receiving coil will have the problem of leakage of magnetic force lines during the power transmission process, and the ferrite plays a role of magnetic shielding. Most of theSIM card holder 130 and thePCB board 110 are metal, and theSIM card cover 150 is provided with ferrite, so that the metal will not generate eddy currents to generate heat and affect efficiency, and the magnetic force lines will not leak out.

此外，SIM卡盖150上设置的铁氧体不会对整机EMC产生影响。具体的，EMC(Electromagnetic Compatibility，电磁兼容性)是指设备或系统在其电磁环境中符合要求运行并不对其环境中的任何设备产生无法忍受的电磁骚扰的能力。因此，EMC包括两个方面的要求：一方面是指设备在正常运行过程中对所在环境产生的电磁骚扰不能超过一定的限值；另一方面是指设备对所在环境中存在的电磁骚扰具有一定程度的抗扰度，即电磁敏感性。在本发明实施例中，不会对整机EMC产生影响是指，SIM卡盖150上设置有铁氧体使得手表不会对其所在环境中产生过高的电磁骚扰，或者，手表对所在环境中的电磁骚扰具有一定程度的抗扰度。In addition, the ferrite disposed on theSIM card cover 150 will not affect the EMC of the whole machine. Specifically, EMC (Electromagnetic Compatibility, Electromagnetic Compatibility) refers to the ability of a device or system to operate in compliance with the requirements in its electromagnetic environment without causing unbearable electromagnetic disturbance to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic disturbance generated by the equipment during normal operation cannot exceed a certain limit; on the other hand, it means that the equipment has a certain Degree of immunity, that is, electromagnetic susceptibility. In the embodiment of the present invention, it will not affect the EMC of the whole machine, which means that theSIM card cover 150 is provided with ferrite so that the watch will not generate excessive electromagnetic disturbance to its environment, or the watch will not affect the environment. There is a certain degree of immunity to electromagnetic disturbances in the system.

为了使手表在无线充电的过程中更少的磁力线外泄以及充电效率更高，所述手表还包括环形的接收线圈铁氧体160，接收线圈铁氧体160设置于无线充电接收线圈140和PCB板110之间，且与无线充电接收线圈140紧密贴合；SIM卡座130的卡槽正对接收线圈铁氧体160的开口。In order to make the watch have less magnetic force leakage and higher charging efficiency during the wireless charging process, the watch also includes a ring-shaped receivingcoil ferrite 160, and the receivingcoil ferrite 160 is arranged on the wirelesscharging receiving coil 140 and the PCB. between theboards 110 , and is in close contact with the wirelesscharging receiving coil 140 ; the card slot of theSIM card holder 130 is facing the opening of thereceiving coil ferrite 160 .

其中，手表中还包括环形的接收线圈铁氧体160，接收线圈铁氧体160设置于无线充电接收线圈140和PCB板110之间，且与无线充电接收线圈140紧密贴合。是为了将无线充电接收线圈140在无线充电过程的磁力线进行屏蔽，阻止其外泄到PCB板110，从而减少发热，提高了充电效率。SIM卡卡片上有若干金属触点170，用于和卡槽上的金属触点接触。SIM卡座130的卡槽正对接收线圈铁氧体160的开口，有利于屏蔽磁力线外泄到SIM卡卡片上的金属触点170。Wherein, the watch also includes a ring-shapedreceiving coil ferrite 160 , the receivingcoil ferrite 160 is arranged between the wirelesscharging receiving coil 140 and thePCB board 110 , and is closely attached to the wirelesscharging receiving coil 140 . The purpose is to shield the magnetic field lines of the wirelesscharging receiving coil 140 during the wireless charging process and prevent them from leaking to thePCB board 110 , thereby reducing heat generation and improving charging efficiency. There areseveral metal contacts 170 on the SIM card, which are used to contact with the metal contacts on the card slot. The slot of theSIM card holder 130 faces the opening of theferrite body 160 of the receiving coil, which is beneficial for shielding the magnetic force lines from leaking to themetal contacts 170 on the SIM card.

手表中装入了SIM卡座130，在该特定的场景中，接收线圈铁氧体160做成环形，接收线圈铁氧体160的环形面在径向上的宽度大于所述无线充电接收线圈140的线圈面的宽度。TheSIM card holder 130 is installed in the watch. In this specific scenario, thereceiving coil ferrite 160 is made into a ring shape, and the width of the annular surface of the receivingcoil ferrite 160 in the radial direction is greater than that of the wirelesscharging receiving coil 140. The width of the coil face.

可选的，接收线圈铁氧体160做成环形，中间开口部分用于内嵌SIM卡座130或SIM卡盖150，其中，环形可以是圆环或矩形环，具体的环形形状可以根据与其内嵌贴合的SIM卡座130或SIM卡盖150进行判断。Optionally, thereceiving coil ferrite 160 is made into a ring shape, and the middle opening part is used to embed theSIM card holder 130 or theSIM card cover 150, wherein the ring shape can be a circular ring or a rectangular ring, and the specific ring shape can be determined according to its internal shape. TheSIM card holder 130 or theSIM card cover 150 is fitted to be judged.

示例性的，图2示出了图1中沿AB方向的一种带无线充电装置的手表的剖面结构示意图。需要说明的是，SIM卡卡片上的若干金属触点170在图2中并未示出。接收线圈铁氧体160的环形面在径向上的宽度大于无线充电接收线圈140线圈面的宽度，这样设置是保证了接收线圈铁氧体160的环形面的接触面积大于无线充电线圈140在平面上的面积，阻止了磁力线外泄。可选的，在无线充电的过程中，发射线圈和接收线圈通常做成圆环形，有利于电能的传输。Exemplarily, FIG. 2 shows a schematic cross-sectional structure diagram of a watch with a wireless charging device along the direction AB in FIG. 1 . It should be noted that themetal contacts 170 on the SIM card are not shown in FIG. 2 . The width of the annular surface of the receivingcoil ferrite 160 in the radial direction is greater than the width of the coil surface of the wirelesscharging receiving coil 140. This arrangement ensures that the contact area of the annular surface of the receivingcoil ferrite 160 is larger than that of thewireless charging coil 140 on the plane. The area prevents the leakage of the magnetic lines of force. Optionally, in the process of wireless charging, the transmitting coil and the receiving coil are generally made into circular rings, which is beneficial to the transmission of electric energy.

此外，无线充电接收线圈140朝向所述PCB板110一侧的线圈面被接收线圈铁氧体160的环形面全部覆盖。In addition, the coil surface of the wirelesscharging receiving coil 140 facing thePCB board 110 is completely covered by the annular surface of the receivingcoil ferrite 160 .

为了起到更好的屏蔽效果，沿无线充电接收线圈140朝向PCB板110一侧的线圈面被接收线圈铁氧体160的环形面全部覆盖。这样会更好的防止磁力线外泄到PCB板110上。In order to achieve a better shielding effect, the coil surface along the side of the wirelesscharging receiving coil 140 facing thePCB 110 is completely covered by the annular surface of the receivingcoil ferrite 160 . This will better prevent the magnetic field lines from leaking to thePCB board 110 .

可选的，无线充电接收线圈140为圆环形时，可以将设置有铁氧体的SIM卡盖150的径向宽度设置成小于无线充电接收线圈140的直径。为了获得较好的充电效率和磁屏蔽效果，SIM卡盖150的径向宽度可以略大于接收线圈铁氧体160的开口，这里不做具体限定，在实际应用中，SIM卡盖150的径向宽度也可以小于接收线圈铁氧体160的开口，只是充电效率和磁屏蔽效果会降低。Optionally, when the wirelesscharging receiving coil 140 is circular, the radial width of theSIM card cover 150 provided with ferrite can be set to be smaller than the diameter of the wirelesscharging receiving coil 140 . In order to obtain better charging efficiency and magnetic shielding effect, the radial width of theSIM card cover 150 can be slightly larger than the opening of the receivingcoil ferrite 160, which is not specifically limited here. In practical applications, the radial width of theSIM card cover 150 The width can also be smaller than the opening of the receivingcoil ferrite 160, but the charging efficiency and magnetic shielding effect will be reduced.

可选的，SIM卡座130焊接在PCB板110上。Optionally, theSIM card holder 130 is welded on thePCB board 110 .

为了使SIM卡座130能够固定在手表上，进而使得SIM卡能够更加牢固的固定在SIM卡座130的卡槽内，将SIM卡座130焊接在PCB板110上，以使SIM卡座130与PCB板110固定为一体。In order to make theSIM card holder 130 be fixed on the watch, and then make the SIM card more firmly fixed in the slot of theSIM card holder 130, theSIM card holder 130 is welded on thePCB board 110, so that theSIM card holder 130 and ThePCB board 110 is fixed as a whole.

为了使用户在充电时方便操作，无需区分手表的方向随意放置手表，所述卡槽的几何中心正对所述手表的表盘的几何中心。In order to facilitate the user's operation during charging, the watch can be placed at will without distinguishing the direction of the watch, and the geometric center of the card slot is directly opposite to the geometric center of the dial of the watch.

将卡槽的几何中心正对手表的表盘的几何中心，这样卡槽与无线充电接收线圈140的位置也会固定。由于在无线充电过程中，发射线圈和接收线圈的位置关系要求相对固定，可选的，当SIM卡座130嵌在无线充电接收线圈140的中间，无线充电接收线圈140的几何中心正对所述手表表盘的几何中心，这样用户在充电时无需区分手表方向随意放置，避免了在充电过程中，手表位置方向需要固定的缺陷。无线充电接收线圈140的几何中心正对所述手表表盘的几何中心，使得在手表在无线充电的过程中，手表的方向发生了变化，无线充电接收线圈140的方向也不会发生变化，无线充电接收线圈140和充电基站的发射线圈的相对位置和方向均不会发生改变。The geometric center of the card slot is aligned with the geometric center of the dial of the watch, so that the position of the card slot and the wirelesscharging receiving coil 140 will also be fixed. Since the positional relationship between the transmitting coil and the receiving coil is required to be relatively fixed during the wireless charging process, optionally, when theSIM card holder 130 is embedded in the middle of the wirelesscharging receiving coil 140, the geometric center of the wirelesscharging receiving coil 140 is facing the The geometric center of the watch dial, so that the user does not need to distinguish the direction of the watch when charging, and avoids the defect that the position and direction of the watch need to be fixed during the charging process. The geometric center of the wirelesscharging receiving coil 140 is facing the geometric center of the dial of the watch, so that during the wireless charging process of the watch, if the direction of the watch changes, the direction of the wirelesscharging receiving coil 140 will not change. The relative position and direction of the receivingcoil 140 and the transmitting coil of the charging base station will not change.
