本申请涉及可折叠电子技术领域，尤其涉及一种阻尼机构、折叠铰链及电子设备。The present application relates to the field of foldable electronic technology, and in particular to a damping mechanism, a folding hinge and an electronic device.
背景技术Background Art
随着柔性折叠屏技术日趋成熟，柔性折叠终端产品已经成为一大趋势，折叠终端产品(如折叠手机、折叠平板、折叠电脑等电子设备)需要满足较高的可靠性，较好的操作体验及外观，这样才能被消费者所接受。折叠较链作为折叠终端产品的核心功能部件，其可靠性和操作体验很大程度取决于阻尼机构的性能。As flexible folding screen technology matures, flexible folding terminal products have become a major trend. Folding terminal products (such as folding mobile phones, folding tablets, folding computers and other electronic devices) need to meet higher reliability, better operating experience and appearance, so that they can be accepted by consumers. As the core functional component of folding terminal products, the reliability and operating experience of the folding hinge largely depend on the performance of the damping mechanism.
阻尼机构是内外折叠设备中提供用户开合手感的关键机构。目前的阻尼机构主要分为两类，即外挂阻尼和轴内阻尼。外挂阻尼在滑块内，采用多组弹簧顶住类球头结构在滑槽内移动，通过弹簧压缩量的变化实现不同的阻尼力。轴内阻尼方案则采用多组弹簧顶住凹凸轮结构，通过旋转轴转动，实现不同的弹簧压缩量，达到改变阻尼力的目的。然而，目前的阻尼结构零件较多，且存在厚度方向占用空间大的问题。The damping mechanism is a key mechanism in the inside-out folding device that provides the user with an opening and closing feel. The current damping mechanisms are mainly divided into two categories, namely external damping and in-axis damping. The external damping is inside the slider, and uses multiple sets of springs to support the ball-like structure to move in the slide groove, and achieves different damping forces by changing the spring compression. The in-axis damping solution uses multiple sets of springs to support the concave cam structure, and through the rotation of the rotating shaft, different spring compression amounts are achieved to achieve the purpose of changing the damping force. However, the current damping structure has many parts and has the problem of occupying a large space in the thickness direction.
发明内容Summary of the invention
为了解决上述技术问题，本申请提供一种阻尼机构、折叠铰链及电子设备。该阻尼机构结构简单，零件较少，拆卸和装配容易难度低，且厚度方向占用空间小，有利于折叠设备进一步轻薄化。In order to solve the above technical problems, the present application provides a damping mechanism, a folding hinge and an electronic device. The damping mechanism has a simple structure, fewer parts, is easy to disassemble and assemble, and occupies little space in the thickness direction, which is conducive to further thinning the folding device.
第一方面，本申请提供一种阻尼机构，包括：In a first aspect, the present application provides a damping mechanism, comprising:
中梁，所述中梁沿第一方向延伸，在第二方向上在所述中梁的相对两侧分别设置门板，所述门板沿所述第一方向延伸，且与所述中梁转动连接，所述第二方向与所述第一方向垂直；A center beam, the center beam extends along a first direction, door panels are respectively arranged on opposite sides of the center beam in a second direction, the door panels extend along the first direction and are rotatably connected to the center beam, and the second direction is perpendicular to the first direction;
在所述中梁和所述门板之间设置有阻尼单元，所述阻尼单元包括摆臂、滑动块、滑槽块和弹性元件，所述摆臂与所述中梁转动连接，与所述门板滑动连接，在所述门板上在第二方向上在所述摆臂的相对两侧分别依次设置所述滑动块、滑槽块和弹性元件，所述滑动块与所述摆臂相接触，所述滑槽块与所述滑动块相接触，所述弹性元件与所述滑槽块相接触，所述摆臂、滑动块、滑槽块和弹性元件构造为通过所述弹性元件使得所述摆臂和所述滑动块之间存在弹性压力，且在所述摆臂相对所述门板滑动时带动所述滑动块相对所述门板从所述门板上的第一位置滑动至第二位置或者从所述门板上的所述第二位置滑动至所述第一位置，并且在所述滑动块滑动时所述摆臂与所述滑动块之间的弹性压力逐渐增大或逐渐减小，当所述滑动块位于所述门板上的第一位置或第二位置时所述摆臂与所述滑动块之间的弹性压力达到极值。A damping unit is arranged between the center beam and the door panel, and the damping unit comprises a swing arm, a sliding block, a sliding groove block and an elastic element, the swing arm is rotatably connected to the center beam and slidably connected to the door panel, and the sliding block, the sliding groove block and the elastic element are respectively arranged in sequence on opposite sides of the swing arm in a second direction on the door panel, the sliding block is in contact with the swing arm, the sliding groove block is in contact with the sliding block, and the elastic element is in contact with the sliding groove block, the swing arm, the sliding block, the sliding groove block and the elastic element are constructed so that an elastic pressure exists between the swing arm and the sliding block through the elastic element, and when the swing arm slides relative to the door panel, the sliding block is driven to slide relative to the door panel from a first position on the door panel to a second position or from the second position on the door panel to the first position, and when the sliding block slides, the elastic pressure between the swing arm and the sliding block gradually increases or decreases, and when the sliding block is located at the first position or the second position on the door panel, the elastic pressure between the swing arm and the sliding block reaches an extreme value.
根据第一方面，本申请的阻尼机构利用摆臂与滑动块、滑槽块和弹性元件之间的挤压形成摩擦力，从而在摆臂滑动过程中提供阻尼。本申请的阻尼机构结构简单，零件较少，拆卸和装配容易难度低，且厚度方向占用空间小，有利于折叠设备进一步轻薄化。并且，本申请的阻尼机构由于当所述滑动块位于所述门板上的第一位置或第二位置时所述摆臂与所述滑动块之间的弹性压力达到极值，因此在折叠和展开过程中，也即滑动块的正反方向运动过程中，摆臂与滑动块之间的摩擦力不同，使得阻尼机构在折叠和展开过程中提供不同的阻尼，这样可以使得折叠设备折叠较难，展开较容易或展开较难，折叠较容易，可以根据具体需求进行设计，为用户提供更好的阻尼体验。According to the first aspect, the damping mechanism of the present application utilizes the extrusion between the swing arm and the sliding block, the slide block and the elastic element to form friction, thereby providing damping during the sliding process of the swing arm. The damping mechanism of the present application has a simple structure, fewer parts, is easy to disassemble and assemble, and occupies less space in the thickness direction, which is conducive to further thinning the folding device. In addition, the damping mechanism of the present application, because the elastic pressure between the swing arm and the sliding block reaches an extreme value when the sliding block is located at the first position or the second position on the door panel, the friction between the swing arm and the sliding block is different during the folding and unfolding process, that is, during the forward and reverse movement of the sliding block, so that the damping mechanism provides different damping during the folding and unfolding process, which can make the folding device more difficult to fold and easier to unfold, or more difficult to unfold and easier to fold, and can be designed according to specific needs to provide users with a better damping experience.
根据第一方面，或者以上第一方面的任意一种实现方式，在所述门板上设置有第一滑槽，所述摆臂在所述第一滑槽内相对所述门板滑动。这样通过设置第一滑槽，可以方便地实现摆臂与门板之间的滑动连接和相对滑动。According to the first aspect, or any implementation of the first aspect above, a first slide groove is provided on the door panel, and the swing arm slides relative to the door panel in the first slide groove. Thus, by providing the first slide groove, the sliding connection and relative sliding between the swing arm and the door panel can be conveniently achieved.
根据第一方面，或者以上第一方面的任意一种实现方式，在所述门板上在第二方向上在所述第一滑槽的相对两侧分别设置第二滑槽和第三滑槽，所述滑动块设置在所述第二滑槽中，所述滑槽块和所述弹性元件设置在所述第三滑槽中。通过设置第二滑槽和第二滑槽可以方便地安装滑动块、滑槽块和弹性元件，并且方便实现滑动块相对门板的滑动。According to the first aspect, or any implementation of the first aspect above, a second slide groove and a third slide groove are respectively provided on opposite sides of the first slide groove in the second direction on the door panel, the sliding block is provided in the second slide groove, and the slide groove block and the elastic element are provided in the third slide groove. By providing the second slide groove and the second slide groove, the sliding block, the slide groove block and the elastic element can be conveniently installed, and the sliding block can be conveniently slid relative to the door panel.
根据第一方面，或者以上第一方面的任意一种实现方式，所述第二滑槽在所述第二方向上的尺寸大于所述滑动块在所述第二方向上的尺寸，所述第三滑槽在所述第二方向上的尺寸与所述滑槽块和所述弹性元件在所述第二方向上的尺寸相等。这样通过限定第二滑槽和第三滑槽的尺寸来使得摆臂相对门板滑动时，滑动块也相对门板滑动，而滑槽块和弹性元件不相对门板滑动。According to the first aspect, or any implementation of the first aspect above, the size of the second slide groove in the second direction is greater than the size of the sliding block in the second direction, and the size of the third slide groove in the second direction is equal to the size of the slide groove block and the elastic element in the second direction. In this way, by limiting the sizes of the second slide groove and the third slide groove, when the swing arm slides relative to the door panel, the sliding block also slides relative to the door panel, while the slide groove block and the elastic element do not slide relative to the door panel.
根据第一方面，或者以上第一方面的任意一种实现方式，所述第二滑槽在所述第二方向上的尺寸小于所述第一滑槽在所述第二方向上的尺寸。这样使得滑动块到达第一位置或第二位置后，摆臂能够继续相对门板滑动，也即在摆臂转动的中间位置阻尼达到极值。According to the first aspect, or any implementation of the first aspect above, the dimension of the second slide groove in the second direction is smaller than the dimension of the first slide groove in the second direction. In this way, after the sliding block reaches the first position or the second position, the swing arm can continue to slide relative to the door panel, that is, the damping reaches an extreme value at the middle position of the swing arm rotation.
根据第一方面，或者以上第一方面的任意一种实现方式，所述第二滑槽在在所述第二方向上的尺寸构造为在所述门板相对所述中梁或所述摆臂相对所述中梁转动预定角度后，所述滑动块位于所述门板上的第一位置或第二位置，所述摆臂与所述滑动块之间的弹性压力达到极值。这样设置使得摆臂或门板转动预定角度后阻尼达到极值不再变化，通过选择合适的角度，可以使折叠铰链或折叠设备在开合运动变化的瞬间，阻尼力也快速跟随产生变化，使用户感受不到滑动块的滑动，提高用户的使用体验。According to the first aspect, or any implementation of the first aspect above, the dimension of the second slide groove in the second direction is configured such that after the door panel rotates relative to the middle beam or the swing arm rotates relative to the middle beam by a predetermined angle, the sliding block is located at the first position or the second position on the door panel, and the elastic pressure between the swing arm and the sliding block reaches an extreme value. This configuration allows the damping to reach an extreme value and no longer change after the swing arm or door panel rotates by a predetermined angle. By selecting a suitable angle, the damping force of the folding hinge or folding device can quickly follow the change at the moment of the opening and closing movement, so that the user cannot feel the sliding of the sliding block, thereby improving the user experience.
根据第一方面，或者以上第一方面的任意一种实现方式，所述预定角度为2-10度。这样设置可以使折叠铰链或折叠设备在开合运动变化的瞬间，阻尼力也快速跟随产生变化，使用户感受不到滑动块的滑动，提高用户的使用体验。According to the first aspect, or any implementation of the first aspect above, the predetermined angle is 2-10 degrees. This setting can make the damping force quickly follow the change at the moment when the folding hinge or folding device changes its opening and closing motion, so that the user cannot feel the sliding of the sliding block, thereby improving the user's experience.
根据第一方面，或者以上第一方面的任意一种实现方式，所述滑动块和所述滑槽块呈楔形状，所述滑动块在所述第一方向上的尺寸沿所述第二方向逐渐减小，所述滑槽块在所述第一方向上的尺寸沿所述第二方向逐渐增大。这样设置使得阻尼机构折叠较难，展开较容易，提高了用户使用折叠设备的阻尼体验。According to the first aspect, or any implementation of the first aspect above, the sliding block and the slide block are wedge-shaped, the size of the sliding block in the first direction gradually decreases along the second direction, and the size of the slide block in the first direction gradually increases along the second direction. This arrangement makes it more difficult to fold the damping mechanism and easier to unfold it, thereby improving the damping experience of the user when using the folding device.

根据第二方面的折叠铰链，由于采用第一方面的阻尼机构，因而类似的优点，结构简单易安装拆卸，且减少了空间占用，利于设备进一步的轻薄化，且在折叠和展开过程中提供不同的阻尼，这样可以使得折叠设备折叠较难，展开较容易或展开较难，折叠较容易，可以根据具体需求进行设计，为用户提供更好的阻尼体验。According to the folding hinge of the second aspect, since the damping mechanism of the first aspect is adopted, similar advantages are achieved, the structure is simple and easy to install and disassemble, and the space occupancy is reduced, which is conducive to further lightweighting of the device, and different damping is provided during the folding and unfolding process, so that the folding device can be more difficult to fold and easier to unfold, or more difficult to unfold and easier to fold. It can be designed according to specific needs to provide users with a better damping experience.

如图1至图3所示，电子设备100包括壳体10、折叠铰链20和柔性显示屏30。折叠铰链20能够发生形变，以使第一壳体11与第二壳体12相对折叠或相对展开。如图1所示，第一壳体11与第二壳体12能够相对展开至展平状态，以使电子设备100处于展平状态。示例性的，第一壳体11与第二壳体12处于展平状态时，两者可以大致呈180°(也允许存在少许偏差，例如165°、177°或者185°)。如图2所示，第一壳体11与第二壳体12能够相对转动(展开或折叠)至中间状态，以使电子设备100处于中间状态。如图3所示，第一壳体11与第二壳体12能够相对折叠至闭合状态，以使电子设备100处于闭合状态。示例性的，第一壳体11与第二壳体12处于闭合状态时，两者能够完全合拢至相互平行(也允许存在少许偏差)。其中，图2所示中间状态，可以为展平状态与闭合状态之间的任意状态。故而，电子设备100可以通过折叠铰链20的形变，在展平状态与闭合状态之间相互切换。As shown in FIGS. 1 to 3 , the electronic device 100 includes a housing 10, a folding hinge 20 and a flexible display screen 30. The folding hinge 20 can be deformed so that the first housing 11 and the second housing 12 can be relatively folded or relatively unfolded. As shown in FIG. 1 , the first housing 11 and the second housing 12 can be relatively unfolded to a flattened state so that the electronic device 100 is in a flattened state. Exemplarily, when the first housing 11 and the second housing 12 are in a flattened state, the two can be approximately 180° (a small deviation is also allowed, such as 165°, 177° or 185°). As shown in FIG. 2 , the first housing 11 and the second housing 12 can be relatively rotated (unfolded or folded) to an intermediate state so that the electronic device 100 is in an intermediate state. As shown in FIG. 3 , the first housing 11 and the second housing 12 can be relatively folded to a closed state so that the electronic device 100 is in a closed state. Exemplarily, when the first housing 11 and the second housing 12 are in a closed state, the two can be completely closed to be parallel to each other (a small deviation is also allowed). 2 can be any state between the flattened state and the closed state. Therefore, the electronic device 100 can switch between the flattened state and the closed state by deforming the folding hinge 20.
一些实施例中，柔性显示屏30用于显示图像。示例性的，柔性显示屏30可以为有机发光二极管(organic light emitting diode,OLED)显示屏，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active matrix organic light emitting diode，AMOLED)显示屏，迷你发光二极管(mini organic light emitting diode)显示屏，微型发光二极管(micro organic light-emitting diode)显示屏，微型有机发光二极管(microorganiclight-emi ttingdiode)显示屏，量子点发光二极管(quantum dot lightemittingdiodes,QLED)显示屏。In some embodiments, the flexible display screen 30 is used to display images. Exemplarily, the flexible display screen 30 can be an organic light emitting diode (OLED) display screen, an active matrix organic light emitting diode or an active matrix organic light emitting diode (AMOLED) display screen, a mini organic light emitting diode (MILLED) display screen, a micro organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, or a quantum dot light-emitting diode (QLED) display screen.
柔性显示屏30包括依次排列的第一非折弯部31、折弯部32以及第二非折弯部33。柔性显示屏30固定于壳体10。例如，柔性显示屏30可以通过胶层粘接于壳体10。柔性显示屏30的第一非折弯部31固定于第一壳体11，第二非折弯部33固定于第二壳体12，在第一壳体11与第二壳体12相对折叠或相对展开的过程中，折弯部32发生形变。如图1所示，第一壳体11与第二壳体12处于展平状态时，柔性显示屏30处于展平形态：如图2所示，第一壳体11与第二壳体12处于中间状态时，柔性显示屏30处于展平形态与闭合形态之间的中间形态：如图3所示，第一壳体11与第二壳体12处于闭合状态时，柔性显示屏30处于闭合形态。其中，电子设备100处于闭合状态时，柔性显示屏30位于壳体10的外侧，柔性显示屏30可以大致呈U型。The flexible display screen 30 includes a first non-bending portion 31, a bending portion 32, and a second non-bending portion 33 arranged in sequence. The flexible display screen 30 is fixed to the housing 10. For example, the flexible display screen 30 can be bonded to the housing 10 by an adhesive layer. The first non-bending portion 31 of the flexible display screen 30 is fixed to the first housing 11, and the second non-bending portion 33 is fixed to the second housing 12. During the relative folding or relative unfolding of the first housing 11 and the second housing 12, the bending portion 32 is deformed. As shown in FIG1, when the first housing 11 and the second housing 12 are in a flattened state, the flexible display screen 30 is in a flattened state; as shown in FIG2, when the first housing 11 and the second housing 12 are in an intermediate state, the flexible display screen 30 is in an intermediate state between the flattened state and the closed state; as shown in FIG3, when the first housing 11 and the second housing 12 are in a closed state, the flexible display screen 30 is in a closed state. Among them, when the electronic device 100 is in a closed state, the flexible display screen 30 is located outside the housing 10, and the flexible display screen 30 can be roughly U-shaped.
在本实施例中，柔性显示屏30能够随折叠铰链20展开或折叠。当电子设备100处于展平状态时，柔性显示屏30处于展平形态，能够全屏进行显示，使得电子设备100具有较大的显示面积，以提高用户的观看体验。当电子设备100处于闭合状态时，电子设备100的平面尺寸较小(具有较小的宽度尺寸)，便于用户携带和收纳。In this embodiment, the flexible display screen 30 can be unfolded or folded along with the folding hinge 20. When the electronic device 100 is in a flat state, the flexible display screen 30 is in a flat state and can display in full screen, so that the electronic device 100 has a larger display area to improve the user's viewing experience. When the electronic device 100 is in a closed state, the plane size of the electronic device 100 is small (with a small width dimension), which is convenient for users to carry and store.
如图4所示，电子设备100包括壳体10、折叠铰链20和柔性屏30。柔性屏30固定在壳体10的一侧表面。电子设备100可沿其中心进行折叠，当可折叠手机处于折叠态时，即，可折叠手机的折叠角度为0，可以减小可折叠手机的尺寸；当可折叠手机处于展平态时，即，可折叠手机的折叠角度为180°，柔性屏30处于最大显示面积的状态，此时用户可以在柔性屏30上进行操作。需要说明的是，折叠角度指的是可折叠手机的左右两部分之间的夹角。与图1至图3所示的电子设备的不同之处在于，图4中电子设备100处于闭合状态时，柔性显示屏30位于壳体10的内侧。As shown in FIG4 , the electronic device 100 includes a housing 10, a folding hinge 20 and a flexible screen 30. The flexible screen 30 is fixed to a side surface of the housing 10. The electronic device 100 can be folded along its center. When the foldable mobile phone is in a folded state, that is, the folding angle of the foldable mobile phone is 0, the size of the foldable mobile phone can be reduced; when the foldable mobile phone is in a flattened state, that is, the folding angle of the foldable mobile phone is 180°, the flexible screen 30 is in a state of maximum display area, and the user can operate on the flexible screen 30. It should be noted that the folding angle refers to the angle between the left and right parts of the foldable mobile phone. The difference from the electronic device shown in FIGS. 1 to 3 is that when the electronic device 100 in FIG4 is in a closed state, the flexible display screen 30 is located on the inner side of the housing 10.
为了便于对本申请实施例的技术方案进行清楚的描述，如图4所示，可定义三个方向，分别为可折叠手机的长度方向(X方向，也称第一方向)，可折叠手机的宽度方向(Y方向，也称第二方向)和可折叠手机的厚度方向(Z方向，也称第三方向)。In order to facilitate a clear description of the technical solution of the embodiment of the present application, as shown in Figure 4, three directions can be defined, namely the length direction of the foldable mobile phone (X direction, also called the first direction), the width direction of the foldable mobile phone (Y direction, also called the second direction) and the thickness direction of the foldable mobile phone (Z direction, also called the third direction).
此外，在本申请实施例中，“上”、“下”、“左”和“右”指的是可折叠手机处于展平态，当用户双手握持可折叠手机且柔性屏30朝向用户时，以用户手部作为参照而确定的方位。In addition, in the embodiments of the present application, "up", "down", "left" and "right" refer to the positions determined with reference to the user's hands when the foldable mobile phone is in a flattened state and the user holds the foldable mobile phone with both hands and the flexible screen 30 is facing the user.
可以理解的是，本实施例是以“电子设备100的转动中心平行于电子设备100的长度方向”为例进行说明的，此时，电子设备100能够实现左右转动，电子设备100的折叠与展开影响到电子设备100的宽度尺寸。在其他一些实施例中，电子设备100的转动中心也可以平行于电子设备100的宽度方向，此时，电子设备100能够实现上下转动，电子设备100的折叠与展开影响到电子设备100的长度尺寸。It is understandable that this embodiment is described by taking "the rotation center of the electronic device 100 is parallel to the length direction of the electronic device 100" as an example. In this case, the electronic device 100 can rotate left and right, and the folding and unfolding of the electronic device 100 affects the width dimension of the electronic device 100. In some other embodiments, the rotation center of the electronic device 100 may also be parallel to the width direction of the electronic device 100. In this case, the electronic device 100 can rotate up and down, and the folding and unfolding of the electronic device 100 affects the length dimension of the electronic device 100.
图5是本申请实施例提供的一种折叠铰链的结构示意图。如图5所示，在本申请一实施例中折叠铰链20包括转轴组件和设置在该转轴组件上的阻尼机构40，该转轴组件包括第一门板21、第二门板22以及位于第一门板21和第二门板22之间的中梁23。在本申请一个实施例中，第一门板21和第二门板22与中梁23转动连接。当第一门板21和第二门板22相对中梁23转动时，可以实现电子设备100的展开或折叠，且在第一门板21和第二门板22相对中梁23转动的过程中，阻尼机构40产生阻尼，为用户提供阻尼体验，提高用户使用电子设备100的阻尼感。第一门板21和第二门板22与中梁23之间的转动连接方式可以采用本领域常用的各种结构，在此不做赘述。FIG5 is a schematic diagram of the structure of a folding hinge provided in an embodiment of the present application. As shown in FIG5, in an embodiment of the present application, the folding hinge 20 includes a shaft assembly and a damping mechanism 40 disposed on the shaft assembly, and the shaft assembly includes a first door panel 21, a second door panel 22, and a center beam 23 located between the first door panel 21 and the second door panel 22. In an embodiment of the present application, the first door panel 21 and the second door panel 22 are rotatably connected to the center beam 23. When the first door panel 21 and the second door panel 22 rotate relative to the center beam 23, the electronic device 100 can be unfolded or folded, and in the process of the first door panel 21 and the second door panel 22 rotating relative to the center beam 23, the damping mechanism 40 generates damping, providing a damping experience for the user, and improving the damping feeling of the user when using the electronic device 100. The rotational connection between the first door panel 21 and the second door panel 22 and the center beam 23 can adopt various structures commonly used in the art, which will not be described here.
在本申请实施例中，折叠铰链20包括一个阻尼机构40，该阻尼机构40沿中梁23的旋转轴的轴向(也即电子设备100的长度方向或X方向)，设置在旋转轴中间位置处。应当理解的是，阻尼机构40的设置数量并不限于一个，可以设置为两个、三个或更多个等，具体可根据柔性显示屏30的尺寸以及所需要的阻尼力进行设置。In the embodiment of the present application, the folding hinge 20 includes a damping mechanism 40, which is arranged at the middle position of the rotation axis along the axial direction of the rotation axis of the middle beam 23 (that is, the length direction or X direction of the electronic device 100). It should be understood that the number of damping mechanisms 40 is not limited to one, and can be set to two, three or more, etc., and can be specifically set according to the size of the flexible display screen 30 and the required damping force.
请再次参阅图1至图3，折叠绞链20位于第一壳体11和第二壳体12之间，该折叠较链20能够使第一壳体11相对于第二壳体12产生靠近或远离第二壳体12的翻转运动。柔性显示屏30装配在第一壳体11、第二壳体12和折叠较链20的表面，并根据折叠较链20的转动随第一壳体11和第二壳体12产生翻转运动。Please refer to Figures 1 to 3 again. The folding hinge 20 is located between the first shell 11 and the second shell 12. The folding hinge 20 can make the first shell 11 flip relative to the second shell 12 to move closer to or away from the second shell 12. The flexible display screen 30 is mounted on the surfaces of the first shell 11, the second shell 12 and the folding hinge 20, and flips along with the first shell 11 and the second shell 12 according to the rotation of the folding hinge 20.
应当理解的是，在该电子设备100中，第一门板21与第一壳体11固定连接，第二门板22与第二壳体12固定连接。当翻转第一壳体11时，第一壳体11带动第一门板21运动，第一门板21绕中梁23运动，同理，在翻转第二壳体12时，第二壳体12带动第二门板22运动，第二门板22绕中梁23运动，从而实现第一壳体11与第二壳体12的相对转动。同理，在转动时可同时朝相反方向翻动第一壳体11和第二壳体12，以实现第一壳体11和第二壳体12的分离或闭合。It should be understood that in the electronic device 100, the first door panel 21 is fixedly connected to the first housing 11, and the second door panel 22 is fixedly connected to the second housing 12. When the first housing 11 is turned over, the first housing 11 drives the first door panel 21 to move, and the first door panel 21 moves around the middle beam 23. Similarly, when the second housing 12 is turned over, the second housing 12 drives the second door panel 22 to move, and the second door panel 22 moves around the middle beam 23, thereby realizing the relative rotation of the first housing 11 and the second housing 12. Similarly, during the rotation, the first housing 11 and the second housing 12 can be flipped in opposite directions at the same time to realize the separation or closing of the first housing 11 and the second housing 12.
在使用电子设备100时，当电子设备100处于展平状态，即，第一壳体11与第二壳体12处于展平状态时，阻尼机构40提供一定阻尼力，该阻尼力可以阻止折叠铰链20铰链被折叠，从而保持第一壳体11和第二壳体12的相对位置不变。当电子设备100处于闭合状态，即，第一壳体11与第二壳体12处于闭合状态时，阻尼机构40提供一定阻尼力，该阻尼力可以使折叠铰链保持折叠状态，从而保持第一壳体11和第二壳体12的相对位置不变。When the electronic device 100 is in use, when the electronic device 100 is in a flattened state, that is, when the first shell 11 and the second shell 12 are in a flattened state, the damping mechanism 40 provides a certain damping force, which can prevent the folding hinge 20 from being folded, thereby maintaining the relative position of the first shell 11 and the second shell 12 unchanged. When the electronic device 100 is in a closed state, that is, when the first shell 11 and the second shell 12 are in a closed state, the damping mechanism 40 provides a certain damping force, which can keep the folding hinge in a folded state, thereby maintaining the relative position of the first shell 11 and the second shell 12 unchanged.
下面结合图6至图11对本申请一实施例提供的阻尼机构的结构和原理进行说明。The structure and principle of the damping mechanism provided in one embodiment of the present application are described below in conjunction with FIGS. 6 to 11 .
如图6至图11所示，本申请实施例提供的阻尼机构40包括第一阻尼单元41和第二阻尼单元42。第一阻尼单元41可以随第一门板21相对中梁23转动，第二阻尼单元42可以随第二门板22相对中梁23转动。第一门板21和第二门板22的相对展开或折叠可以使第一壳体11与第二壳体12能够相对折叠或相对展开。也即，第一壳体11与第二壳体12的相对折叠或相对展开会带动第一阻尼单元41和第二阻尼单元42的相对展开或折叠。第一阻尼单元41和第二阻尼单元42的结构相同，不同之处在于设置位置不同，第一阻尼单元41和第二阻尼单元42分别设置在第一门板21和第二门板22之上。在本申请实施例中以第一阻尼单元41为例来说明阻尼单元的结构和原理。As shown in FIGS. 6 to 11 , the damping mechanism 40 provided in the embodiment of the present application includes a first damping unit 41 and a second damping unit 42. The first damping unit 41 can rotate relative to the center beam 23 with the first door panel 21, and the second damping unit 42 can rotate relative to the center beam 23 with the second door panel 22. The relative expansion or folding of the first door panel 21 and the second door panel 22 can enable the first shell 11 and the second shell 12 to be relatively folded or relatively expanded. That is, the relative folding or relative expansion of the first shell 11 and the second shell 12 will drive the relative expansion or folding of the first damping unit 41 and the second damping unit 42. The first damping unit 41 and the second damping unit 42 have the same structure, except that they are arranged at different positions. The first damping unit 41 and the second damping unit 42 are respectively arranged on the first door panel 21 and the second door panel 22. In the embodiment of the present application, the first damping unit 41 is taken as an example to illustrate the structure and principle of the damping unit.
如图6至图11所示，第一阻尼单元41包括摆臂43、滑动块44、滑槽块45和弹性元件46。摆臂43的第一端与中梁23转动连接，第二端与第一门板21滑动连接。即，摆臂43可以相对中梁23转动，并且相对第一门板21滑动。具体地，在第一门板21上设置有第一滑槽24，在第一门板21相对中梁23转动时，摆臂43随第一门板21一起相对中梁23转动，并且在转动过程中，摆臂43在第一滑槽24中相对第一门板21滑动。当折叠铰链20处于展平状态时，摆臂43的第二端处于第一滑槽24靠近中梁23一侧的边缘位置。当折叠铰链20处于折叠转施工图时，摆臂43的第二端处于第一滑槽24远离中梁23一侧的边缘位置。As shown in FIGS. 6 to 11 , the first damping unit 41 includes a swing arm 43, a sliding block 44, a slide block 45 and an elastic element 46. The first end of the swing arm 43 is rotatably connected to the center beam 23, and the second end is slidably connected to the first door panel 21. That is, the swing arm 43 can rotate relative to the center beam 23 and slide relative to the first door panel 21. Specifically, a first slide 24 is provided on the first door panel 21. When the first door panel 21 rotates relative to the center beam 23, the swing arm 43 rotates relative to the center beam 23 together with the first door panel 21, and during the rotation process, the swing arm 43 slides relative to the first door panel 21 in the first slide 24. When the folding hinge 20 is in a flattened state, the second end of the swing arm 43 is at an edge position of the first slide 24 close to the center beam 23. When the folding hinge 20 is in a folding state, the second end of the swing arm 43 is at an edge position of the first slide 24 away from the center beam 23.
如图6至图11所示，在第一门板21上在第一滑槽24的相对两侧分别邻近第一滑槽24依次设置有滑动块44、滑槽块45和弹性元件46。也即，在摆臂43在x方向上的相对两侧分别依次设置有滑动块44、滑槽块45和弹性元件46。滑动块44、滑槽块45和弹性元件46安装在第一门板21上，滑动块44与摆臂43的侧壁相接触，滑槽块45与滑动块44相接触，弹性元件46与滑槽块45相接触。当装配完成之后，弹性元件46处于压缩状态，从而对滑槽45施加弹性压力，进而对滑动块44施加弹性压力。这样当摆臂43相对第一门板21滑动时，由于摆臂43的侧壁与滑动块44之间存在弹性压力，因而在滑动过程中，摆臂43的侧壁与滑动块44之间存在摩擦阻尼。该阻尼在折叠铰链20从展平状态到折叠状态的过程中阻止折叠，在从折叠状态到展平状态的过程中阻尼展开，从而为用户提供阻尼体验。As shown in Fig. 6 to Fig. 11, a sliding block 44, a chute block 45 and an elastic element 46 are sequentially arranged on opposite sides of the first chute 24 on the first door panel 21, adjacent to the first chute 24. That is, a sliding block 44, a chute block 45 and an elastic element 46 are sequentially arranged on opposite sides of the swing arm 43 in the x direction. The sliding block 44, the chute block 45 and the elastic element 46 are installed on the first door panel 21, the sliding block 44 contacts the side wall of the swing arm 43, the chute block 45 contacts the sliding block 44, and the elastic element 46 contacts the chute block 45. After the assembly is completed, the elastic element 46 is in a compressed state, thereby applying elastic pressure to the chute 45, and then applying elastic pressure to the sliding block 44. In this way, when the swing arm 43 slides relative to the first door panel 21, due to the elastic pressure between the side wall of the swing arm 43 and the sliding block 44, there is friction damping between the side wall of the swing arm 43 and the sliding block 44 during the sliding process. The damping prevents folding when the folding hinge 20 is moved from the flat state to the folded state, and damps unfolding when the folding hinge 20 is moved from the folded state to the flat state, thereby providing a damping experience for the user.
在本申请一实施例中，在第一门板21上在第一滑槽24的相对两侧分别依次设置第二滑槽25和第三滑槽(图未示出)。滑动块44安装在第一滑槽中，滑槽块45和弹性元件46按在第二滑槽。第二滑槽25在Y方向上的尺寸大于滑动块44在Y方向上的尺寸。第三滑槽在Y方向上的尺寸与滑槽块45和弹性元件46在Y方向上的尺寸大致相等。在摆臂43在第一滑槽24内滑动时，摆臂43会带动滑动块44在第二滑槽内滑动。In one embodiment of the present application, a second slide groove 25 and a third slide groove (not shown) are sequentially arranged on opposite sides of the first slide groove 24 on the first door panel 21. The sliding block 44 is installed in the first slide groove, and the slide groove block 45 and the elastic element 46 are pressed in the second slide groove. The size of the second slide groove 25 in the Y direction is larger than the size of the sliding block 44 in the Y direction. The size of the third slide groove in the Y direction is substantially equal to the size of the slide groove block 45 and the elastic element 46 in the Y direction. When the swing arm 43 slides in the first slide groove 24, the swing arm 43 drives the sliding block 44 to slide in the second slide groove.
在本申请一实施例中，第二槽25在Y方向上的尺寸小于第一槽24在Y方向上的尺寸。在本文中，第一槽24、第二槽25、第三滑槽、滑动块44、滑槽块45和弹性元件46靠近中梁23一侧的端部称为第一端，远离中梁23一侧的端部称为第二端。当滑动块44的端部到达第二槽25的第一端或第二端时将不再滑动。第二滑槽25的第二端的位置基于折叠铰链的阻尼设计需求确定，可以根据需要采用不同尺寸的第二滑槽25和滑动块44以满足不同的设计需求。In one embodiment of the present application, the size of the second slot 25 in the Y direction is smaller than the size of the first slot 24 in the Y direction. In this article, the end of the first slot 24, the second slot 25, the third slot, the sliding block 44, the slot block 45 and the elastic element 46 close to the middle beam 23 is called the first end, and the end away from the middle beam 23 is called the second end. When the end of the sliding block 44 reaches the first end or the second end of the second slot 25, it will no longer slide. The position of the second end of the second slot 25 is determined based on the damping design requirements of the folding hinge, and different sizes of second slots 25 and sliding blocks 44 can be used as needed to meet different design requirements.
在本申请一实施例中，第三槽在Y方向上的尺寸与第一槽24在Y方向上的尺寸大致相等。大致相等表示相等或相差很小。In one embodiment of the present application, the size of the third groove in the Y direction is substantially equal to the size of the first groove 24 in the Y direction. Substantially equal means equal or with a small difference.
应当理解的是，第二滑槽25和第三滑槽可以分别单独设置，也可以一体设置。当第二滑槽25和第三滑槽可以分别单独设置时，第二滑槽25和第三滑槽相邻设置，且确保滑动块44和滑槽块45能够彼此接触。当第二滑槽25和第三滑槽一体设置时，槽大致呈L型。It should be understood that the second chute 25 and the third chute can be provided separately or integrally. When the second chute 25 and the third chute can be provided separately, the second chute 25 and the third chute are provided adjacent to each other, and ensure that the sliding block 44 and the chute block 45 can contact each other. When the second chute 25 and the third chute are provided integrally, the groove is generally L-shaped.
如图11所示，在本申请一实施例中，滑动块44和滑槽块45为楔形块，滑动块44在X方向上的尺寸沿Y方向逐渐减小，滑槽块45在X方向上的尺寸沿Y方向逐渐增大。因此，在折叠铰链20从展平到折叠的过程中，摆臂43带动滑动块44在第二槽25中在Y方向上向远离中梁23的方向滑动，并且由于滑动块44在X方向上的尺寸沿Y方向逐渐减小，因此在滑动块44在Y方向上向远离中梁23的方向滑动时，滑动块44对滑槽块45的挤压增大，使得弹性元件46的位移增大，弹性压力增大，从而使得滑动块44与摆臂43之间的摩擦力逐渐增大。当滑动块44的第二端与第二槽25的第二端接触时，滑动块44不再滑动，滑动块44与摆臂43之间的摩擦力达到最大。随后摆臂43继续在第二槽25中在Y方向上向远离中梁23的方向滑动，摆臂43与滑动块44之间的摩擦力不再变化，阻尼一致。As shown in FIG. 11 , in one embodiment of the present application, the sliding block 44 and the chute block 45 are wedge-shaped blocks, the size of the sliding block 44 in the X direction gradually decreases along the Y direction, and the size of the chute block 45 in the X direction gradually increases along the Y direction. Therefore, in the process of the folding hinge 20 from flattening to folding, the swing arm 43 drives the sliding block 44 to slide in the second groove 25 in the Y direction in the direction away from the middle beam 23, and because the size of the sliding block 44 in the X direction gradually decreases along the Y direction, when the sliding block 44 slides in the Y direction in the direction away from the middle beam 23, the sliding block 44 increases the pressure on the chute block 45, so that the displacement of the elastic element 46 increases, the elastic pressure increases, and the friction between the sliding block 44 and the swing arm 43 gradually increases. When the second end of the sliding block 44 contacts the second end of the second groove 25, the sliding block 44 no longer slides, and the friction between the sliding block 44 and the swing arm 43 reaches the maximum. Then, the swing arm 43 continues to slide in the second groove 25 in the Y direction in a direction away from the middle beam 23 , and the friction force between the swing arm 43 and the sliding block 44 does not change any more, and the damping is consistent.
相应地，在折叠铰链20从折叠到展平的过程中，开始时，滑动块44处于第二端与第二槽24第二端相接触的位置，滑动块44与摆臂43之间的摩擦力最大，此时阻尼最大，随着滑动块44的滑动，滑动块44对滑槽块45的挤压逐渐减小，弹性元件46的位移减小，弹性元件46对滑槽块45的弹性压力逐渐减小，滑动块44与摆臂43之间的摩擦力逐渐减小，阻尼减小。当滑动块44的第一端与第二滑槽25的第一端相接触时，滑动块44与摆臂43之间的摩擦力达到最小，此后滑动块44与摆臂43之间的摩擦力不再变化。Accordingly, in the process of the folding hinge 20 from folding to flattening, at the beginning, the sliding block 44 is in a position where the second end contacts the second end of the second slot 24, the friction between the sliding block 44 and the swing arm 43 is the largest, and the damping is the largest at this time. As the sliding block 44 slides, the pressing of the sliding block 44 on the slide block 45 gradually decreases, the displacement of the elastic element 46 decreases, the elastic pressure of the elastic element 46 on the slide block 45 gradually decreases, the friction between the sliding block 44 and the swing arm 43 gradually decreases, and the damping decreases. When the first end of the sliding block 44 contacts the first end of the second slide slot 25, the friction between the sliding block 44 and the swing arm 43 reaches the minimum, and thereafter the friction between the sliding block 44 and the swing arm 43 no longer changes.
综上可知，当滑动块44在X方向上的尺寸沿Y方向逐渐减小，滑槽块45在X方向上的尺寸沿Y方向逐渐增大时，折叠铰链20从折叠到展平的过程中，阻尼逐渐减小，当达到最小时不再变化，而折叠铰链20从展平到折叠的过程中，阻尼逐渐增大，当达到最大时不再变化。这导致折叠铰链在相同角度(第一门板21和第二门板22的夹角相同)的阻尼，在折叠过程和展开过程大小是不同。In summary, when the size of the sliding block 44 in the X direction gradually decreases along the Y direction, and the size of the chute block 45 in the X direction gradually increases along the Y direction, the damping of the folding hinge 20 gradually decreases during the process from folding to flattening, and does not change when it reaches the minimum, while the damping of the folding hinge 20 gradually increases during the process from flattening to folding, and does not change when it reaches the maximum. This results in the damping of the folding hinge at the same angle (the angle between the first door panel 21 and the second door panel 22 is the same) being different in the folding process and the unfolding process.
应当理解的是，当滑动块44在X方向上的尺寸沿Y方向逐渐增大，滑槽块45在X方向上的尺寸沿Y方向逐渐减小时，折叠铰链的阻尼变化与上述过程相反，即，折叠铰链20从折叠到展平的过程中，阻尼逐渐增大，当达到最大时不再变化，而折叠铰链20从展平到折叠的过程中，阻尼逐渐减小，当达到最小时不再变化。这导致折叠铰链在相同角度(第一门板21和第二门板22的夹角相同)的阻尼，在折叠过程和展开过程大小是不同。It should be understood that when the size of the sliding block 44 in the X direction gradually increases along the Y direction, and the size of the chute block 45 in the X direction gradually decreases along the Y direction, the damping change of the folding hinge is opposite to the above process, that is, the damping gradually increases during the process of the folding hinge 20 from folding to flattening, and no longer changes when it reaches the maximum, while the damping gradually decreases during the process of the folding hinge 20 from flattening to folding, and no longer changes when it reaches the minimum. This results in the damping of the folding hinge at the same angle (the angle between the first door panel 21 and the second door panel 22 is the same) being different in the folding process and the unfolding process.
综上可知，采用本申请实施例提供的阻尼机构，折叠过程和展开过程阻尼大小不一样，因此可以基于折叠设备的阻尼需要进行选择合适的设计方案。示例性地，例如当折叠设备需要折叠时阻尼大，展开时阻尼小，也即折叠较难，展开较容易时，则可以采用滑动块44在X方向上的尺寸沿Y方向逐渐减小，滑槽块45在X方向上的尺寸沿Y方向逐渐增大的设计。反之，当折叠设备需要折叠时阻尼小，展开时阻尼大，也即折叠较容易，展开较难时，则可以采用滑动块44在X方向上的尺寸沿Y方向逐渐增大，滑槽块45在X方向上的尺寸沿Y方向逐渐减小的设计。In summary, it can be seen that by using the damping mechanism provided in the embodiment of the present application, the damping size of the folding process and the unfolding process is different, so a suitable design scheme can be selected based on the damping needs of the folding device. For example, when the folding device needs to have a large damping when folding and a small damping when unfolding, that is, it is difficult to fold and easier to unfold, then a design can be adopted in which the size of the sliding block 44 in the X direction gradually decreases along the Y direction, and the size of the chute block 45 in the X direction gradually increases along the Y direction. On the contrary, when the folding device needs to have a small damping when folding and a large damping when unfolding, that is, it is easier to fold and more difficult to unfold, then a design can be adopted in which the size of the sliding block 44 in the X direction gradually increases along the Y direction, and the size of the chute block 45 in the X direction gradually decreases along the Y direction.
进一步地，在本申请实施例中，可以根据阻尼达到极值(最大值或最小值)的位置设计第二滑槽在Y方向上的尺寸。第二滑槽在Y方向上的尺寸越大，折叠铰链20的阻尼达到极值所需要的转动角度越大，相应地阻尼的极值也越大或越小。示例性地，在本申请一实施例中，需要折叠或展开过程中阻尼很快达到极值，也即折叠铰链转动很小的角度阻尼便达到极值，因此，第二滑槽25在Y方向上的尺寸相对滑动块44在Y方向上的尺寸略微大一些。示例性地，在本申请一实施例中，折叠或展开过程中，第一门板21和第二门板22转动2-3度(例如2度、2.5度或3度)，阻尼便达到极值。例如，以图6-图11所示的折叠铰链，从展平到折叠的过程中，第一门板21和/或第二门板22相对展平时的平面转动2-3度，折叠铰链的阻尼便达到最大值。Further, in an embodiment of the present application, the size of the second chute in the Y direction can be designed according to the position where the damping reaches the extreme value (maximum value or minimum value). The larger the size of the second chute in the Y direction, the larger the rotation angle required for the damping of the folding hinge 20 to reach the extreme value, and the corresponding extreme value of the damping is also larger or smaller. Exemplarily, in an embodiment of the present application, the damping needs to reach the extreme value very quickly during the folding or unfolding process, that is, the damping reaches the extreme value when the folding hinge rotates a very small angle, so the size of the second chute 25 in the Y direction is slightly larger than the size of the sliding block 44 in the Y direction. Exemplarily, in an embodiment of the present application, during the folding or unfolding process, the first door panel 21 and the second door panel 22 rotate 2-3 degrees (for example, 2 degrees, 2.5 degrees or 3 degrees), and the damping reaches the extreme value. For example, with the folding hinge shown in Figures 6-11, in the process from flattening to folding, the first door panel 21 and/or the second door panel 22 rotate 2-3 degrees relative to the plane when flattened, and the damping of the folding hinge reaches the maximum value.
本申请实施例提供的阻尼机构，通过摆臂43、滑动块44、滑槽块45和弹性元件46之间的相互作用即可为折叠设备提供阻尼，并且由于滑动块44、滑槽块45为楔形块，The damping mechanism provided in the embodiment of the present application can provide damping for the folding device through the interaction between the swing arm 43, the sliding block 44, the slide block 45 and the elastic element 46, and because the sliding block 44 and the slide block 45 are wedge-shaped blocks,
如图6-图11所示，在本申请一实施例中弹性件46呈片状结构，其可以由金属材料或具有弹性的有机材料，例如橡胶等制作，在本申请中不做具体限定。As shown in FIG. 6 to FIG. 11 , in one embodiment of the present application, the elastic member 46 is in a sheet-like structure, which can be made of a metal material or an elastic organic material, such as rubber, etc., which is not specifically limited in the present application.
示例性地，在本申请实施例中，弹性件46朝靠近远离第一槽24的方向弯曲，在阻尼机构40从展平状态到折叠状态的过程中，弹性件46逐渐被压缩，弯曲程度逐渐增大，阻尼力逐渐增大，达到最大值后不再变化。Illustratively, in the embodiment of the present application, the elastic member 46 bends in a direction approaching and away from the first groove 24. During the process of the damping mechanism 40 changing from a flattened state to a folded state, the elastic member 46 is gradually compressed, the degree of bending gradually increases, and the damping force gradually increases, and no longer changes after reaching a maximum value.
应当理解的是，通过选择合适的弹性元件46可以调节折叠铰链20折叠过程中的阻尼大小。弹性元件46的弹性系数越大，位移越大，弹性压力也越大。It should be understood that the damping during the folding process of the folding hinge 20 can be adjusted by selecting a suitable elastic element 46. The larger the elastic coefficient of the elastic element 46, the greater the displacement and the greater the elastic pressure.
应当理解的是，本申请实施例提供的阻尼机构40和折叠铰链20既可以应用于图1至图3所示的外折电子设备，也可以应用于图4所示的内折电子设备，或者其它实施例提供的上下翻折电子设备或其它类型的折叠设备。It should be understood that the damping mechanism 40 and folding hinge 20 provided in the embodiment of the present application can be applied to the outward-folding electronic device shown in Figures 1 to 3, the inward-folding electronic device shown in Figure 4, or the upside-down folding electronic device or other types of folding devices provided in other embodiments.
