The first base 231 is rotatably connected to a rotating member 233 on opposite sides respectively. One end of each rotating member 233 away from the first base 231 is rotatably connected to a connecting member 234. The abutting member 235 is located between the rotating member 233 and the first elastic member 237. A first cam 2330 is provided on the side of each rotating member 233 facing the abutting member 235. Two abutting cams 2350 are provided on the side of the abutting member 235 facing the rotating member 233. One end of the first elastic member 237 abuts against the abutting member 235, and the other end of the first elastic member 237 abuts against the first base 231. The first elastic member 237 elastically pushes the abutting member 235 so that The first cams 2330 of the two rotating members 233 are rotatably against the two abutting cams 2350 respectively; at the same time, the side of the rotating member 233 away from the first cam 2330 is rotatably against the first base 231. When the rotating member 233 rotates relative to the first base 231, there is a friction torque between the rotating member 233 and the abutting member 235, that is, there is a friction torque between the first cam 2330 and the corresponding abutting cam 2350, and at the same time, there is a friction resistance between the rotating member 233 and the first base 231; specifically, the side of the rotating member 233 away from the abutting member 235 abuts against the first base 231 and has a friction resistance, so as to limit the rotation of the rotating member 233 relative to the first base 231 and the abutting member 255.

When the support assembly 28 is in a flattened state, the front faces of the two side support members 281 and the front face of the middle support member 280 are coplanar, and the bendable area 31 of the flexible screen 30 is connected to the front face of the middle support member 280 and the front face of the side support member 281; when the two side support members 281 are in a folded state, the front faces of the two side support members 281 and the front face of the middle support member 280 enclose a space with a teardrop-shaped or U-shaped cross-section, so that the bendable area 31 of the flexible screen 30 is bent into a teardrop shape or a U-shape; in this embodiment, the bendable area 31 of the flexible screen 30 is bent into a teardrop shape. When the rotating member 233 rotates relative to the first base 231, the first cam 2330 of the rotating member 233 rotationally pushes the corresponding top cam 2350 so that the top member 235 moves along the first direction (i.e., the X-axis direction) to squeeze the first elastic member 237; at this time, the friction torque between the first cam 2330 and the top cam 2350 and the friction resistance between the rotating member 233 and the first base 231 are used to limit the rotation of the rotating member 233 relative to the first base 231 and the top member 235. In the absence of external force, the rotating member 233 remains stationary relative to the first base 231 and the top member 235 to achieve the hovering of the hinge device 22, thereby achieving the hovering of the electronic device 100.

本发明的电子设备100的支撑组件28设置于转动组件23上，转动件233可转动地连接于第一基座231与连接件234之间，支撑组件28连接于第一基座231、转动件233及连接件234，抵顶件235沿第一方向滑动地连接于第一基座231，转动件233与抵顶件235之间通过第一凸轮2330与抵顶凸轮2350可转动地抵持，第一弹性件237弹性抵推抵顶件235抵顶转动件233，使得转动件233与第一基座231可转动地抵顶。当转动件233相对于第一基座231转动时，转动件233的第一凸轮2330转动地抵持抵顶件235的抵顶凸轮2350使得抵顶件235沿第一方向移动而挤压第一弹性件237，以使第一弹性件237弹性变形。此时，转动件233与抵顶件235之间具有摩擦扭力且转动件233与第一基座231之间具有摩擦阻力，在不受外力的情况下，该摩擦扭力和该摩擦阻力能限位转动件233相对于第一基座231保持不动，从而使得支撑组件28保持弯折状态或展平状态，以实现支撑组件28的悬停，使得电子设备100具有悬停效果；其次，转轴装置22的悬停效果通过转动件233与抵顶件235之间的摩擦扭力和转动件233与第一基座231之间的摩擦阻力共同实现的，因此，转轴装置22的悬停效果稳定；另外，第一弹性件237弹性抵推抵顶件235抵顶转动件233，以使转动件233抵顶第一基座231，使得转轴装置22的结构紧凑，转轴装置22的体积减小，从而减小转轴装置22占用折叠壳体20的内部空间，不仅有利于主板 或电池等其他元件的布局，且有利于小型化发展；还有，转轴装置22的结构简单，制造成本较低，且各部件之间的连接可靠性高，整机强度提升。The support assembly 28 of the electronic device 100 of the present invention is disposed on the rotating assembly 23, the rotating member 233 is rotatably connected between the first base 231 and the connecting member 234, the support assembly 28 is connected to the first base 231, the rotating member 233 and the connecting member 234, the abutting member 235 is slidably connected to the first base 231 along the first direction, the rotating member 233 and the abutting member 235 are rotatably abutted by the first cam 2330 and the abutting cam 2350, and the first elastic member 237 elastically pushes the abutting member 235 against the rotating member 233, so that the rotating member 233 and the first base 231 are rotatably abutted. When the rotating member 233 rotates relative to the first base 231, the first cam 2330 of the rotating member 233 rotatably abuts the abutting cam 2350 of the abutting member 235, so that the abutting member 235 moves along the first direction and squeezes the first elastic member 237, so that the first elastic member 237 is elastically deformed. At this time, there is a friction torque between the rotating member 233 and the abutting member 235, and there is a friction resistance between the rotating member 233 and the first base 231. In the absence of external force, the friction torque and the friction resistance can limit the rotating member 233 to remain stationary relative to the first base 231, so that the support assembly 28 remains in a bent state or a flattened state to achieve the hovering of the support assembly 28, so that the electronic device 100 has a hovering effect; secondly, the hovering effect of the rotating shaft device 22 is jointly achieved by the friction torque between the rotating member 233 and the abutting member 235 and the friction resistance between the rotating member 233 and the first base 231, so the hovering effect of the rotating shaft device 22 is stable; in addition, the first elastic member 237 elastically pushes the abutting member 235 to abut the rotating member 233, so that the rotating member 233 abuts the first base 231, so that the structure of the rotating shaft device 22 is compact, the volume of the rotating shaft device 22 is reduced, thereby reducing the internal space occupied by the rotating shaft device 22 in the folding shell 20, which is not only beneficial to the motherboard or the layout of other components such as batteries, and is conducive to miniaturization; in addition, the structure of the shaft device 22 is simple, the manufacturing cost is low, the connection reliability between the components is high, and the strength of the whole machine is improved.
需要说明的是，本发明中的所述第一方向指第二抵持件255相对于第一基座231的滑动方向，也就是第一方向为平行于坐标的X轴方向；所述第二方向指转轴装置22在展平状态下扭力件253能相对于连接件234能滑动地方向，也就是第二方向为平行于坐标的Y轴方向；第三方向与第一方向和第二方向垂直，也就是第三方向为平行于坐标的Z轴方向。It should be noted that the first direction in the present invention refers to the sliding direction of the second supporting member 255 relative to the first base 231, that is, the first direction is parallel to the X-axis direction of the coordinate; the second direction refers to the direction in which the torque member 253 of the rotating shaft device 22 can slide relative to the connecting member 234 in the flattened state, that is, the second direction is parallel to the Y-axis direction of the coordinate; the third direction is perpendicular to the first direction and the second direction, that is, the third direction is parallel to the Z-axis direction of the coordinate.

During the rotation of the rotating member 233 relative to the first base 231, the rotating member 233 and the resisting member 235 can both move along the rotation axis O. The first elastic member 237 is squeezed by the resisting member 235 to extend and retract along the first direction. The resisting member 235 exerts a resisting force along the first direction on the rotating member 233 on the first base 231.

At this time, the two opposite ends of the first elastic member 237 elastically abut the corresponding abutting member 235 and the connecting portion 2316 respectively, so that the two abutting cams 2350 of the abutting member 235 respectively cooperate with the first cams 2330 of the two rotating members 233 and abut against each other, and the ends of the two rotating members 233 away from the first elastic member 237 abut against each other with the first base 231, that is, the first damping surface 2310 and the second damping surface 2338 fit each other, and at the same time, the two opposite ends of the second elastic member 254 respectively abut the second abutting member 255 and the clamping member 257, so that the two first abutting members 252 The cam 2520 cooperates with the second cam 2530 of the pair of torque members 253 and abuts against each other, the two second abutting cams 2550 of the second abutting member 255 cooperate with the third cam 2537 of the pair of torque members 253 and abut against each other, the second base 258 abuts against the pair of torque members 253, that is, the fourth damping surface 2586 and the third damping surface 2538a fit each other; if the pre-elastic force of the first elastic member 237 is F1, the abutting member 235 is subjected to a pre-elastic force of 2F1; if the pre-elastic force of the second elastic member 254 is F2, the second abutting member 255 is subjected to a pre-elastic force of 3F2. Since the rotating assembly 23 and the torsion assembly 25 are independent of each other, the torsion assembly 25 is detachably connected to the rotating assembly 23, therefore, the rotating assembly 23 and the torsion assembly 25 can be separated to test the torque separately, which is convenient for the assembly and testing of the rotating shaft device 22 in mass production. Since the middle support member 280 is fixedly connected to the first base 231 and the second base 258, it is not affected by the axial force of the rotating component 23; the torque member 253, the first abutment member 252, the second abutment member 255 and the linkage mechanism 259 in the torsion assembly 25 are all assembled between the first base 231 and the second base 258 and have a shorter span, so the axial force can be well eliminated by the rigidity of the parts, and the deformation of the middle support member 280 is less affected.
当连接件234带动转动件233相对于第一基座231转动时，连接件234也带动扭力件253相对于第二基座258转动，两个扭力件253通过联动机构259实现同步折叠或同步展开，使得两个侧部支撑件281同步相互折叠或同步相互展开，从而实现转轴装置22的折叠或展开。在转轴装置22的折叠或展开的过程中，由于第一弹性件237相对的两端分别被抵顶件235和第一基座231的连接部2316抵顶，第二弹性件254相对的两端分别被第二抵持件255和夹持件257抵顶，当两个扭力件253分别围绕对应的转轴251同步转动时，扭力件253通过第二凸轮2530转动地抵推第一抵持件252的第一抵持凸轮2520及通 过第三凸轮2537转动地抵推第二抵持件255的第二抵持凸轮2550，使得一对转轴251沿第一方向(即X轴方向)相对于第二基座258移动，第二抵持件255和夹持件257挤压第二弹性件254；同时，第一基座231上的两个转动件233分别相对于第一基座231同步转动，使每一转动件233的第一凸轮2330转动地抵推对应的抵顶件235的抵顶凸轮2350，使得抵顶件235挤压第一弹性件237。第一弹性件237的弹性力抵推抵顶件235，使抵顶件235的两个抵顶凸轮2350与对应的第一凸轮2330相互抵顶地啮合，同时，抵顶件235抵推两个转动件233与第一定位座231紧密抵顶，且两个转动件233背离抵顶件235的侧面与第一基座231紧密抵顶，即第二阻尼面2338与第一阻尼面2310相互紧贴；第二弹性件254的弹性力抵推第二抵持件255，使第二抵持件255的第二抵持凸轮2550与对应的第三凸轮2537相互抵顶地啮合，扭力件253与第二基座258相互抵顶，以及扭力件253的第二凸轮2530与对应的第一抵持凸轮2520相互抵顶地啮合。也就是转动件233的第一凸轮2330与对应的抵顶凸轮2350之间具有摩擦扭力，第二凸轮2530与对应的第一抵持凸轮2520之间具有摩擦扭力，第三凸轮2537与对应的第二抵持凸轮2550之间具有摩擦扭力，且转动件233与第一基座231之间具有摩擦阻力，以及扭力件253与第二基座258之间具有摩擦阻力。当扭力件253围绕对应的转轴251转动时，第一凸轮2330与抵顶凸轮2350之间的摩擦扭力、第二凸轮2530与第一抵持凸轮2520之间的摩擦扭力、第三凸轮2537与第二抵持凸轮2550之间的摩擦扭力、转动件233的第二阻尼面2338与第一基座231的第一阻尼面2310之间的摩擦阻力，以及扭力件253的第三阻尼面2538a与第二基座258的第四阻尼面2586之间的摩擦阻力，使得转轴装置22具有较好的悬停效果。When the connecting member 234 drives the rotating member 233 to rotate relative to the first base 231, the connecting member 234 also drives the torsion member 253 to rotate relative to the second base 258. The two torsion members 253 are folded or unfolded synchronously through the linkage mechanism 259, so that the two side support members 281 are folded or unfolded synchronously with each other, thereby realizing the folding or unfolding of the shaft device 22. During the folding or unfolding process of the shaft device 22, since the opposite ends of the first elastic member 237 are respectively abutted by the abutting member 235 and the connecting portion 2316 of the first base 231, and the opposite ends of the second elastic member 254 are respectively abutted by the second abutting member 255 and the clamping member 257, when the two torsion members 253 rotate synchronously around the corresponding rotating shaft 251, the torsion member 253 rotates to push the first abutting cam 2520 of the first abutting member 252 and the through cam 2530. The third cam 2537 rotationally pushes the second supporting cam 2550 of the second supporting member 255, so that a pair of rotating shafts 251 move relative to the second base 258 along the first direction (i.e., the X-axis direction), and the second supporting member 255 and the clamping member 257 squeeze the second elastic member 254; at the same time, the two rotating members 233 on the first base 231 rotate synchronously relative to the first base 231, so that the first cam 2330 of each rotating member 233 rotationally pushes the corresponding supporting cam 2350 of the supporting member 235, so that the supporting member 235 squeezes the first elastic member 237. The elastic force of the first elastic member 237 pushes the resisting member 235, so that the two resisting cams 2350 of the resisting member 235 and the corresponding first cams 2330 are mutually resisted and meshed. At the same time, the resisting member 235 pushes the two rotating members 233 to tightly resist the first positioning seat 231, and the sides of the two rotating members 233 facing away from the resisting member 235 are tightly resisted against the first base 231, that is, the second damping surface 2338 and the first damping surface 2310 are tightly attached to each other; the elastic force of the second elastic member 254 pushes the second supporting member 255, so that the second supporting cam 2550 of the second supporting member 255 and the corresponding third cam 2537 are mutually resisted and meshed, the torque member 253 and the second base 258 are mutually resisted, and the second cam 2530 of the torque member 253 and the corresponding first resisting cam 2520 are mutually resisted and meshed. That is, there is friction torque between the first cam 2330 of the rotating member 233 and the corresponding top cam 2350, there is friction torque between the second cam 2530 and the corresponding first retaining cam 2520, there is friction torque between the third cam 2537 and the corresponding second retaining cam 2550, there is friction resistance between the rotating member 233 and the first base 231, and there is friction resistance between the torque member 253 and the second base 258. When the torque member 253 rotates around the corresponding rotating shaft 251, the friction torque between the first cam 2330 and the top cam 2350, the friction torque between the second cam 2530 and the first abutting cam 2520, the friction torque between the third cam 2537 and the second abutting cam 2550, the friction resistance between the second damping surface 2338 of the rotating member 233 and the first damping surface 2310 of the first base 231, and the friction resistance between the third damping surface 2538a of the torque member 253 and the fourth damping surface 2586 of the second base 258, make the rotating shaft device 22 have a better hovering effect.
如图3-图5所示，将转轴装置22由展平状态进行弯折时，将其中一连接件234相对于第一基座231向另一连接件234弯折，该其中一连接件234带动对应的转动件233的第一圆弧轨2332在第一基座231的第一圆弧槽2312中转动，转动件233抵推抵顶件235沿第一方向(即X轴方向)移动而挤压第一弹性件237，并带动对应的扭力件253围绕对应的转轴251转动，扭力件253抵推第二抵持件255沿转轴251的轴向移动而挤压第二弹性件254；同时，扭力件253上的第一齿轮2590绕转轴251转动以带动从动齿轮组件2592的两个从动齿轮2593同步转动，使得另一扭力件253绕对应的转轴251转动，从而实现两个扭力件253的同步折叠；同时，第一基座231上的两个转动件233分别同步转动而相互靠拢，以带动两个侧部支撑件281同步相互靠拢，直至两个侧部支撑件281的正面与中部支撑件280的正面围成横截面成水滴状。在第一基座231上的两个转动件233相互靠拢的过程中，第一基座231上的转动件233抵推对应的抵顶件235沿第一方向(即X轴方向)移动而挤压第一弹性件237，在两个扭力件253相对于第二基座258转动而相互靠拢的过程中，扭力件253抵推第二抵持件255沿转轴251的轴向移动而挤压第二弹性件254。与第一弹性件237抵顶的抵顶件235的抵顶凸轮2350与对应的第一凸轮2330之间的轴向力等于两个第一弹性件237的弹力之和；每一转轴251上的第一抵持凸轮2520与第二凸轮2530之间的轴向力等于第二抵持凸轮2550与第三凸轮2537之间的轴向力，该轴向力等于三个第二弹性件254的弹力之和。第一凸轮2330与抵顶凸轮2350之间的摩擦扭力、第二凸轮2530与第一抵持凸轮2520之间的摩擦扭力、第三凸轮2537与第二抵持凸轮2550之间的摩擦扭力、每一转动件233与第一基座231之间的摩擦阻力，以及每一扭力件253与第二基座258之间的摩擦阻力使两个侧部支撑件281限位在任意角度；优选地，两个侧部支撑件281能被限定在70度至130度之间的特定角度。As shown in FIGS. 3 to 5 , when the rotating shaft device 22 is bent from a flat state, one of the connecting members 234 is bent toward the other connecting member 234 relative to the first base 231, and the one of the connecting members 234 drives the first arc track 2332 of the corresponding rotating member 233 to rotate in the first arc groove 2312 of the first base 231, and the rotating member 233 pushes the abutting member 235 to move along the first direction (i.e., the X-axis direction) to squeeze the first elastic member 237, and drives the corresponding torsion member 253 to rotate around the corresponding rotating shaft 251, and the torsion member 253 pushes the second abutting member 255 along the rotating shaft 251. The second elastic member 254 is squeezed by axial movement; at the same time, the first gear 2590 on the torsion member 253 rotates around the rotating shaft 251 to drive the two driven gears 2593 of the driven gear assembly 2592 to rotate synchronously, so that the other torsion member 253 rotates around the corresponding rotating shaft 251, thereby realizing the synchronous folding of the two torsion members 253; at the same time, the two rotating members 233 on the first base 231 rotate synchronously and approach each other, so as to drive the two side support members 281 to approach each other synchronously, until the front faces of the two side support members 281 and the front faces of the middle support member 280 form a water drop-shaped cross section. When the two rotating members 233 on the first base 231 are brought close to each other, the rotating member 233 on the first base 231 pushes the corresponding abutting member 235 to move along the first direction (i.e., the X-axis direction) to squeeze the first elastic member 237. When the two torsion members 253 rotate relative to the second base 258 and come close to each other, the torsion member 253 pushes the second abutting member 255 to move along the axial direction of the rotating shaft 251 to squeeze the second elastic member 254. The axial force between the abutting cam 2350 of the abutting member 235 abutting against the first elastic member 237 and the corresponding first cam 2330 is equal to the sum of the elastic forces of the two first elastic members 237; the axial force between the first abutting cam 2520 and the second cam 2530 on each rotating shaft 251 is equal to the axial force between the second abutting cam 2550 and the third cam 2537, and the axial force is equal to the sum of the elastic forces of the three second elastic members 254.

在其他的使用方式中，可以将两个连接件234朝相向方向一同转动，每一连接件234通过对应的转 动件233的第一圆弧轨2332与对应的第一基座231的第一圆弧槽2312相对转动，以使两个连接件234相对于第一基座231同步转动而相互靠拢，转动件233的第一凸轮2330与对应的抵顶凸轮2350相互抵顶，以使抵顶件235沿第一方向(即X轴方向)移动而挤压第一弹性件237；两个连接件234分别带动两个扭力件253通过联动机构259绕对应的转轴251同步转动而相互靠拢，第二凸轮2530与第一抵持凸轮2520相互转动地抵顶，第三凸轮2537与第二抵持凸轮2550相互转动地抵顶，以使第二抵持件255沿转轴251的轴向移动而挤压第二弹性件254；使得两个侧部支撑件281同步相互靠拢，直至两个侧部支撑件281的正面与第一基座231的正面围成横截面成水滴状。In other usage modes, the two connecting members 234 can be rotated together in opposite directions, and each connecting member 234 can rotate in the corresponding direction. The first arc track 2332 of the movable member 233 rotates relative to the first arc groove 2312 of the corresponding first base 231, so that the two connecting members 234 rotate synchronously relative to the first base 231 and approach each other, and the first cam 2330 of the rotating member 233 and the corresponding abutting cam 2350 abut each other, so that the abutting member 235 moves along the first direction (i.e., the X-axis direction) and squeezes the first elastic member 237; the two connecting members 234 respectively drive the two torsion members 253 to rotate synchronously around the corresponding rotating shaft 251 through the linkage mechanism 259 and approach each other, the second cam 2530 and the first abutting cam 2520 rotate and abut each other, and the third cam 2537 and the second abutting cam 2550 rotate and abut each other, so that the second abutting member 255 moves along the axial direction of the rotating shaft 251 and squeezes the second elastic member 254; so that the two side support members 281 synchronously approach each other until the front faces of the two side support members 281 and the front face of the first base 231 form a cross section in the shape of a water drop.
当转轴装置22由完全弯折状态进行展开时，将其中一连接件234相对于第一基座231朝远离另一连接件234展开，该其中一连接件234带动转动件233的第一圆弧轨2332在第一基座231的第一圆弧槽2312中转动，转动件233抵推抵顶件235沿第一方向(即X轴方向)移动而挤压第一弹性件237，并带动对应的扭力件253围绕对应的转轴251转动，以使两个扭力件253相互远离，扭力件253抵推第二抵持件255沿转轴251的轴向移动而挤压第二弹性件254；同时，扭力件253上的第一齿轮2590绕转轴251转动以带动从动齿轮组件2592的两个从动齿轮2593同步转动，使得另一扭力件253绕对应的转轴251转动，从而实现两个扭力件253的同步展开；同时，第一基座231上的两个转动件233分别同步转动而相互展开，以带动两个侧部支撑件281同步相互展开，以带动两个侧部支撑件281同步相互展开，直至两个侧部支撑件281与中部支撑件280呈展平状。When the rotating shaft device 22 is unfolded from the fully bent state, one of the connecting members 234 is unfolded relative to the first base 231 toward the other connecting member 234, and the one of the connecting members 234 drives the first arc track 2332 of the rotating member 233 to rotate in the first arc groove 2312 of the first base 231, and the rotating member 233 pushes the abutting member 235 to move along the first direction (i.e., the X-axis direction) to squeeze the first elastic member 237, and drives the corresponding torsion member 253 to rotate around the corresponding rotating shaft 251, so that the two torsion members 253 are away from each other, and the torsion member 253 pushes the second abutting member 255 along the axis of the rotating shaft 251. At the same time, the first gear 2590 on the torsion member 253 rotates around the rotating shaft 251 to drive the two driven gears 2593 of the driven gear assembly 2592 to rotate synchronously, so that the other torsion member 253 rotates around the corresponding rotating shaft 251, thereby realizing the synchronous expansion of the two torsion members 253; at the same time, the two rotating members 233 on the first base 231 rotate synchronously and expand with each other, so as to drive the two side support members 281 to expand with each other synchronously, so as to drive the two side support members 281 to expand with each other synchronously, until the two side support members 281 and the middle support member 280 are flattened.
在侧部支撑件281相对于第一基座231展平过程中，转动件233的第一凸轮2330与对应的抵顶凸轮2350之间的轴向力等于两个第一弹性件237的弹力之和；每一转轴251上的第二凸轮2530与第一抵持凸轮2520之间的轴向力等于第三凸轮2537与第二抵持凸轮2550之间的轴向力，该轴向力等于三个第二弹性件254的弹力之和。第一凸轮2330与抵顶凸轮2350之间的摩擦扭力，第二凸轮2530与第一抵持凸轮2520之间的摩擦扭力、第三凸轮2537与第二抵持凸轮2550之间的摩擦扭力、转动件233的第二阻尼面2338与第一基座231的第一阻尼面2310之间的摩擦阻力，以及扭力件253的第三阻尼面2538a与第二基座258的第四阻尼面2586之间的摩擦阻力使两个侧部支撑件281限位在任意角度，优选地，两个侧部支撑件281之间限位在130度至70度之间的特定角度。During the flattening process of the side support member 281 relative to the first base 231, the axial force between the first cam 2330 of the rotating member 233 and the corresponding abutting cam 2350 is equal to the sum of the elastic forces of the two first elastic members 237; the axial force between the second cam 2530 and the first abutting cam 2520 on each rotating shaft 251 is equal to the axial force between the third cam 2537 and the second abutting cam 2550, and the axial force is equal to the sum of the elastic forces of the three second elastic members 254.

在其他的使用方式中，可以将两个连接件234朝相反方向一同转动，每一连接件234通过对应的转动件233的第一圆弧轨2332与对应的第一基座231的第一圆弧槽2312相对转动，以使两个连接件234相对于第一基座231同步转动而相互展开，转动件233的第一凸轮2330与抵顶凸轮2350相互转动地抵顶而抵推抵顶件235沿第一方向(即X轴方向)移动而挤压第一弹性件237；两个连接件234分别带动两个扭力件253分别围绕一对转轴251转动而相互远离，扭力件253抵推第二抵持件255沿转轴251的轴向移动而挤压第二弹性件254；使得两个侧部支撑件281同步相互远离，直至两个侧部支撑件281的正面与第一基座231的正面齐平。In other usage modes, the two connecting members 234 can be rotated together in opposite directions, and each connecting member 234 rotates relative to the first arc track 2332 of the corresponding rotating member 233 and the first arc groove 2312 of the corresponding first base 231, so that the two connecting members 234 rotate synchronously relative to the first base 231 and expand each other, and the first cam 2330 of the rotating member 233 and the abutting cam 2350 rotate against each other to push the abutting member 235 to move along the first direction (i.e., the X-axis direction) and squeeze the first elastic member 237; the two connecting members 234 respectively drive the two torsion members 253 to rotate around a pair of rotating shafts 251 respectively and move away from each other, and the torsion member 253 pushes the second abutting member 255 to move along the axial direction of the rotating shaft 251 to squeeze the second elastic member 254; so that the two side support members 281 move away from each other synchronously until the front sides of the two side support members 281 are flush with the front side of the first base 231.

The frame 21 includes a front side 211, a back side 213, two opposite side surfaces 214 and two end surfaces 215. The hinge device 22 is connected between two adjacent end surfaces 215 of the two frames 21. The bendable area 31 of the flexible screen 30 is attached to the front side of the hinge device 22, and the non-bending area 33 of the flexible screen 30 is connected to the front side 211 of the frame 21. A receiving groove 216 is provided on the end surface 215 of each frame 21 facing the hinge device 22. The receiving groove 216 passes through the front side 211 of the frame 21, and the opposite ends of the receiving groove 216 pass through the opposite side surfaces 214 of the frame 21. The opposite sides of the hinge device 22 are respectively accommodated in the receiving grooves 216 of the two frames 21, and each connecting member 234 is connected to the corresponding frame 21. The back side 213 of the frame 21 is provided with a plurality of receiving spaces (not shown in the figure), and the receiving spaces are used to install electronic components such as circuit boards and batteries.
将安装完成的转轴装置22置于两个框体21之间，将中部支撑件280相对的两侧的连接件234分别容置于两个框体21的收容槽216中，并将两个连接件234分别固定连接于两个框体21。此时，两个框体21的正面211、两个侧部支撑件281的正面及中部支撑件280的正面共面。柔性屏30的背面连接于两个框体21的正面211及转轴装置22的正面，具体地，可折弯区31正对转轴装置22，两个非折弯区33分别正对两个框体21的正面。当柔性屏30处在展平状态时，中部支撑件280的正面与两个侧部支撑件281的正面齐平，第一凸轮2330与抵顶凸轮2350相互抵顶地啮合，第二凸轮2530与第一抵持凸轮2520相互抵顶地啮合，第三凸轮2537与第二抵持凸轮2550相互抵顶地啮合，转动件233与第一基座231抵顶，以及扭力件253与第二基座258抵顶，以限定两个侧部支撑件281保持展平状态；且能使转轴装置22中各元件间的连接更紧凑，从而减小转轴装置22的整体体积，降低占用壳体20的内部空间，有利于主板或电池等其他元件的布局，有利于电子设备100的小型化；其次，由于侧部支撑件281的正面与中部支撑件280的正面共面，因此，柔性屏30在展平时不会受到段差处的冲击，柔性屏30不会出现彩点、亮点等不良问题，保证柔性屏30的可靠性，同时，也提升柔性屏30的触摸手感，提高用户使用体验。Place the installed hinge device 22 between the two frames 21, place the connecting members 234 on the opposite sides of the middle support member 280 in the receiving grooves 216 of the two frames 21, and fix the two connecting members 234 to the two frames 21. At this time, the front faces 211 of the two frames 21, the front faces of the two side support members 281, and the front face of the middle support member 280 are coplanar. The back of the flexible screen 30 is connected to the front faces 211 of the two frames 21 and the front face of the hinge device 22. Specifically, the bendable area 31 faces the hinge device 22, and the two non-bending areas 33 face the front faces of the two frames 21, respectively. When the flexible screen 30 is in a flattened state, the front of the middle support member 280 is flush with the front of the two side support members 281, the first cam 2330 and the abutting cam 2350 are mutually abutted and meshed, the second cam 2530 and the first abutting cam 2520 are mutually abutted and meshed, the third cam 2537 and the second abutting cam 2550 are mutually abutted and meshed, the rotating member 233 abuts against the first base 231, and the torsion member 253 abuts against the second base 258, so as to limit the two side support members 281 to remain in a flattened state; and the rotating shaft device 22 The connection between the components is more compact, thereby reducing the overall volume of the hinge device 22 and reducing the internal space occupied by the shell 20, which is beneficial to the layout of other components such as the motherboard or the battery, and is beneficial to the miniaturization of the electronic device 100; secondly, since the front of the side support member 281 is coplanar with the front of the middle support member 280, the flexible screen 30 will not be impacted by the step difference when flattened, and the flexible screen 30 will not have color spots, bright spots and other defects, thereby ensuring the reliability of the flexible screen 30. At the same time, it also improves the touch feel of the flexible screen 30 and improves the user experience.
弯折电子设备100时，对电子设备100的两个框体21至少其中一个施加折叠的力，使连接于两个框体21的连接件234相对于第一基座231朝相互邻近的方向转动，带动两个转动件233相对于第一基座231转动而相互靠拢、两个扭力件253通过联动机构259同步折叠，以实现转轴装置22的两个侧部支撑件281相互折叠，柔性屏30的可折弯区31随转轴装置22弯折，直至柔性屏30的两个非折弯区33的正面相互贴合，可折弯区31弯折成水滴状，从而实现电子设备100的无缝折叠。When the electronic device 100 is bent, a folding force is applied to at least one of the two frames 21 of the electronic device 100, so that the connecting member 234 connected to the two frames 21 rotates relative to the first base 231 in a direction close to each other, driving the two rotating members 233 to rotate relative to the first base 231 and move closer to each other, and the two torsion members 253 are synchronously folded through the linkage mechanism 259, so that the two side support members 281 of the hinge device 22 are folded with each other, and the bendable area 31 of the flexible screen 30 is bent along with the hinge device 22 until the front sides of the two non-bending areas 33 of the flexible screen 30 are attached to each other, and the bendable area 31 is bent into a water drop shape, thereby realizing seamless folding of the electronic device 100.
在弯折电子设备100的过程中，每一转动件233的第一凸轮2330与抵顶件235的抵顶凸轮2350之间的摩擦扭力、每一转轴251上的扭力件253的第二凸轮2530与第一抵持凸轮2520之间的摩擦扭力和第三凸轮2537与第二抵持凸轮2550之间的摩擦扭力抵抗柔性屏30的反弹力，以使两个侧部支撑件281之间相对定位在特定角度，能使两个框体21限位在70度至130度之间的特定角度。柔性屏30的可折弯区31弯折围成水滴形，减少弯折后的可折弯区31的占空比，从而能减小电子设备100的整体厚度。In the process of bending the electronic device 100, the friction torque between the first cam 2330 of each rotating member 233 and the abutting cam 2350 of the abutting member 235, the friction torque between the second cam 2530 of the torque member 253 on each rotating shaft 251 and the first abutting cam 2520, and the friction torque between the third cam 2537 and the second abutting cam 2550 resist the rebound force of the flexible screen 30, so that the two side support members 281 are relatively positioned at a specific angle, and the two frames 21 can be limited to a specific angle between 70 degrees and 130 degrees. The bendable area 31 of the flexible screen 30 is bent into a teardrop shape, reducing the duty cycle of the bendable area 31 after bending, thereby reducing the overall thickness of the electronic device 100.
在对电子设备100的其他折叠方式中，还可以同时对两个框体21施加折叠的力，两个框体21分别带动转动件233相对于第一基座231转动向靠近柔性屏30的一侧转动，带动两个扭力件253围绕对应的转轴251转动向靠近柔性屏30的一侧转动，并通过转轴装置22以实现电子设备100的折叠。In other folding methods of the electronic device 100, a folding force can also be applied to the two frames 21 at the same time. The two frames 21 respectively drive the rotating members 233 to rotate relative to the first base 231 toward the side close to the flexible screen 30, and drive the two torsion members 253 to rotate around the corresponding rotating shaft 251 toward the side close to the flexible screen 30, and realize the folding of the electronic device 100 through the rotating shaft device 22.
当需要展平电子设备100时，向外拉开其中一框体21，使连接于两个框体21上的两个转动件233相对于第一基座231转动而相互远离，两个扭力件253分别围绕对应的转轴251同步转动而相互远离，以实现转轴装置22的两个侧部支撑件281相互展开，使得柔性屏30的可折弯区31随转轴装置22展平，柔性屏30的可折弯区31随转轴装置22展开，直至柔性屏30的可折弯区31完全展平，从而实现电子设备100的展平。When the electronic device 100 needs to be flattened, one of the frames 21 is pulled outward so that the two rotating members 233 connected to the two frames 21 rotate relative to the first base 231 and move away from each other, and the two torsion members 253 rotate synchronously around the corresponding rotating shafts 251 and move away from each other, so that the two side support members 281 of the rotating shaft device 22 can be unfolded with each other, so that the bendable area 31 of the flexible screen 30 is flattened with the rotating shaft device 22, and the bendable area 31 of the flexible screen 30 is unfolded with the rotating shaft device 22 until the bendable area 31 of the flexible screen 30 is completely flattened, thereby realizing the flattening of the electronic device 100.
在展平电子设备100的过程中，每一转动件233的第一凸轮2330与抵顶凸轮2350之间的摩擦扭力、每一转轴251上的第二凸轮2530与第一抵持凸轮2520之间的摩擦扭力和第三凸轮2537与第二抵持凸轮2550之间的摩擦扭力抵抗柔性屏30的反弹力，以使两个框体21之间相对定位在特定角度，优选地， 该特定角度为70度至130度之间。In the process of flattening the electronic device 100, the friction torque between the first cam 2330 of each rotating member 233 and the abutting cam 2350, the friction torque between the second cam 2530 on each rotating shaft 251 and the first abutting cam 2520, and the friction torque between the third cam 2537 and the second abutting cam 2550 resist the rebound force of the flexible screen 30, so that the two frames 21 are relatively positioned at a specific angle. Preferably, The specific angle is between 70 degrees and 130 degrees.
在对电子设备100的其他折叠方式中，还可以同时对两个框体21施加向外拉开的力，两个框体21分别带动第一基座231的两个转动件233及一对扭力件253向远离柔性屏30的一侧转动，并通过转轴装置22以实现电子设备100的展开。In other folding methods of the electronic device 100, an outward pulling force can be applied to the two frames 21 at the same time, and the two frames 21 respectively drive the two rotating parts 233 of the first base 231 and a pair of torsion parts 253 to rotate toward the side away from the flexible screen 30, and realize the unfolding of the electronic device 100 through the hinge device 22.

Since there is friction torque between the rotating member 233 and the abutting member 235, there is friction torque between the torque member 253 and the first abutting member 252, and there is friction torque between the torque member 253 and the second abutting member 255, when the electronic device 100 is not subjected to external force, these friction torques can limit the rotating member 233 to remain stationary relative to the first base 231 and the torque member 253 to remain stationary relative to the second base 258, so as to realize the hovering of the two side support members 281, so that the electronic device 100 has a hovering effect; secondly, there is friction resistance between the rotating member 233 and the first base 231. There is friction resistance between the torque member 253 and the second base 258, so that the hovering effect of the electronic device 100 is better; in addition, the opposite ends of the first elastic member 237 elastically abut the connecting portion 2316 and the abutting member 235 of the first base 231, and the opposite ends of the second elastic member 254 elastically abut the second abutting member 255 and the clamping member 257, so that the structure of the hinge device 22 is compact, the volume of the hinge device 22 is reduced, thereby reducing the internal space occupied by the hinge device 22 in the folding shell 20, which is not only beneficial to the layout of other components such as the motherboard or battery, but also beneficial to the development of miniaturization; the hinge device 22 has a simple structure, a low manufacturing cost, and a high connection reliability between the components, thereby improving the strength of the whole machine.
