转轴机构23用于实现第二壳体22与第一壳体21的可转动连接，以支持折叠屏10在展开状态与折叠状态之间折叠。具体的，转轴机构23能在展开状态和折叠状态之间切换。当转轴机构23处于展开状态时，折叠屏10、包括转轴机构23的支撑装置20以及包括该支撑装置20的可折叠电子设备100也处于展开状态，第一壳体21与第二壳体22之间的夹角，以及第一显示区域11与第二显示区域12之间的夹角大致呈180°。当转轴机构23处于折叠状态时，折叠屏10、包括转轴机构23的支撑装置20以及包括该支撑装置20的可折叠电子设备100也处于折叠状态，第一壳体21与第二壳体22之间的夹角，以及第一显示区域11与第二显示区域12之间的夹角大致呈360°。The hinge mechanism 23 is used to realize the rotatable connection between the second casing 22 and the first casing 21, so as to support the folding of the folding screen 10 between the unfolded state and the folded state.

请参阅图4，图4为相关技术中的转轴机构23的示意图。转轴机构23包括基座231、第一摆臂230a、第一转轴230b、第二摆臂230c和第二转轴230d。Please refer to FIG. 4 . FIG. 4 is a schematic diagram of a rotating shaft mechanism 23 in the related art. The rotating shaft mechanism 23 includes a base 231 , a first swing arm 230 a , a first rotating shaft 230 b , a second swing arm 230 c and a second rotating shaft 230 d.
第一摆臂230a和第二摆臂230c设在基座231的相对两侧。第一摆臂230a借助第一转轴230b与基座231可转动地连接，第二摆臂230c借助第二转轴230d与基座231可转动连接。第一摆臂230a与第一壳体21相连，第二摆臂230c与第二壳体22相连。可以理解的是，第一摆臂230a与第一壳体21可以直接相连，也可以间接相连。同样的，第二摆臂230c与第二壳体22可以直接相连，也可以间接相连。The first swing arm 230 a and the second swing arm 230 c are disposed on opposite sides of the base 231 . The first swing arm 230a is rotatably connected to the base 231 through the first rotating shaft 230b, and the second swing arm 230c is rotatably connected to the base 231 through the second rotating shaft 230d.

It can be understood that the first swing arm 230a and the first casing 21 may be connected directly or indirectly. Likewise, the second swing arm 230c may be directly connected to the second housing 22 or may be indirectly connected.
当第一壳体21在外力作用下旋转时，第一摆臂230a随第一壳体21转动，进而可以通过第一摆臂230a带动第一转轴230b相对基座231转动。当第二壳体22在外力作用下旋转时，第二摆臂230c随第二壳体22转动，进而可以通过第二摆臂230c带动第二转轴230d相对基座231转动，以实现第一壳体21与第二壳体22之间的相对转动，使可折叠电子设备100在展开状态与折叠状态之间切换。When the first casing 21 rotates under the action of external force, the first swing arm 230a rotates with the first casing 21 , and then the first swing arm 230a can drive the first rotating shaft 230b to rotate relative to the base 231 . When the second casing 22 rotates under the action of external force, the second swing arm 230c rotates with the second casing 22, and then the second swing arm 230c can drive the second rotating shaft 230d to rotate relative to the base 231, so as to realize the first casing The relative rotation between the body 21 and the second housing 22 makes the foldable electronic device 100 switch between the unfolded state and the folded state.
为了保证可折叠电子设备100能保持在展开状态和折叠状态，以提升用户体验感，请参阅图4，转轴机构23还包括阻尼结构。阻尼结构用于在可折叠电子设备100处于展开状态时，给第一壳体21和第二壳体22施加阻尼，以使得可折叠电子设备100保持在展开状态。和/或阻尼结构还用于在可折叠电子设备100处于折叠状态时，给第一壳体21和第二壳体22施加阻尼，使得可折叠电子设备100保持在折叠状态。In order to ensure that the foldable electronic device 100 can be kept in the unfolded state and the folded state to improve user experience, please refer to FIG. 4 , the hinge mechanism 23 also includes a damping structure. The damping structure is used to apply damping to the first casing 21 and the second casing 22 when the foldable electronic device 100 is in the unfolded state, so that the foldable electronic device 100 remains in the unfolded state. And/or the damping structure is also used to apply damping to the first housing 21 and the second housing 22 when the foldable electronic device 100 is in the folded state, so that the foldable electronic device 100 remains in the folded state.
本实施例中的阻尼结构包括第一阻尼结构230e和第二阻尼结构230f，其中，第一阻尼结构230e用于给第一壳体21施加阻尼，第二阻尼结构230f用于给第二壳体22施加阻尼，第一阻尼结构230e的结构与第二阻尼结构230f的结构相同，下面以第一阻尼结构230e为例解释其构成部分。The damping structure in this embodiment includes a first damping structure 230e and a second damping structure 230f, wherein the first damping structure 230e is used to apply damping to the first casing 21, and the second damping structure 230f is used to apply damping to the second casing 21. 22 to apply damping, the structure of the first damping structure 230e is the same as that of the second damping structure 230f, and the first damping structure 230e is used as an example to explain its components below.
请参阅图4，第一阻尼结构230e包括第一凸轮230e1、第二凸轮230e2、第一弹簧230e3和第一限位件230e4。第一凸轮230e1套设在第一转轴230b上且与第一转轴230b相对固定，第二凸轮230e2可活动地套设于第一转轴230b。第一凸轮230e1包括第一凸轮面，第二凸轮230e2包括第二凸轮面，第二凸轮面适于与第一凸轮面啮合。第一限位件230e4固定连接在第一转轴230b上，且位于第二凸轮230e2的远离第一凸轮230e1的一侧。第一弹簧230e3套设在第一转轴230b上，第一弹簧230e3的一端与第二凸轮230e2相连，第一弹簧230e3的另一端与第一限位件230e4相连。Referring to FIG. 4 , the first damping structure 230e includes a first cam 230e1 , a second cam 230e2 , a first spring 230e3 and a first limiting member 230e4 . The first cam 230e1 is sleeved on the first rotating shaft 230b and relatively fixed to the first rotating shaft 230b, and the second cam 230e2 is movably sleeved on the first rotating shaft 230b. The first cam 230e1 includes a first cam surface, and the second cam 230e2 includes a second cam surface adapted to engage with the first cam surface. The first limiting member 230e4 is fixedly connected to the first rotating shaft 230b, and is located on a side of the second cam 230e2 away from the first cam 230e1. The first spring 230e3 is sleeved on the first rotating shaft 230b, one end of the first spring 230e3 is connected to the second cam 230e2, and the other end of the first spring 230e3 is connected to the first limiting member 230e4.
当转轴机构23处于展开状态或者折叠状态时，第一凸轮230e1面与第二凸轮230e2面相啮合，第一弹簧230e3处于压缩蓄能状态，此时可以通过第一弹簧230e3对第二凸轮230e2施加朝向第一凸轮230e1的挤压力，该挤压力可以使得第一摆臂230a产生展开力或闭合力，进而可以使转轴机构23保持在展开状态或折叠状态。When the shaft mechanism 23 is in the unfolded or folded state, the surface of the first cam 230e1 meshes with the surface of the second cam 230e2, and the first spring 230e3 is in the state of compressing and storing energy. The extrusion force of the first cam 230e1 can cause the first swing arm 230a to generate an unfolding force or a closing force, thereby keeping the hinge mechanism 23 in an unfolded state or a folded state.
然而，上述相关技术中的阻尼结构存在以下问题：一方面，阻尼结构的零部件较多，组装工序复杂，且需要足够的Z向空间；另一方面，随着对可折叠电子设备100厚度的要求越来越高，转轴机构23的宽度越来越窄，转轴机构23的宽度减小，使得第一弹簧230e3的线径也随之减小，进而第一弹簧230e3的弹力减小，提供不了足够的阻尼力。再一方面，转轴机构23的宽度减小，第一凸轮面与第二凸轮面也随之减小，使得第一凸轮面和第二凸轮面受到的压强增大，进而增大了第一凸轮面和第二凸轮面的磨损量，转轴机构23的使用寿命短。However, the damping structure in the above-mentioned related art has the following problems: on the one hand, the damping structure has many parts, the assembly process is complicated, and sufficient Z-direction space is required; on the other hand, as the thickness of the foldable electronic device 100 increases, As the requirements become higher and higher, the width of the rotating shaft mechanism 23 becomes narrower and narrower, and the width of the rotating shaft mechanism 23 decreases, so that the wire diameter of the first spring 230e3 also decreases accordingly, and then the elastic force of the first spring 230e3 decreases, which cannot provide Sufficient damping force. On the other hand, as the width of the rotating shaft mechanism 23 decreases, the first cam surface and the second cam surface also decrease accordingly, so that the pressure on the first cam surface and the second cam surface increases, thereby increasing the pressure of the first cam surface. The amount of wear of the surface and the second cam surface, the service life of the rotating shaft mechanism 23 is short.
