Specifically, the folding mechanism can be, but is not limited to, a hinge mechanism, a shaft mechanism, an elastic mechanism, etc.
在本申请中，可折叠电子设备600具有展开状态与折叠状态，其中展开状态指的是第一壳体310及第二壳体320处于完全相互展开时的状态，也可以理解为柔性屏200的可弯折区210和非弯折区220表面齐平的状态；折叠状态指的是第一壳体310及第二壳体320处于完全相互折叠时的状态，也可以理解为柔性屏200中可弯折区210两侧的两个非弯折区220相互靠近时的状态。In the present application, the foldable electronic device 600 has an unfolded state and a folded state, wherein the unfolded state refers to the state when the first shell 310 and the second shell 320 are completely unfolded with each other, which can also be understood as the state in which the surfaces of the bendable area 210 and the non-bending area 220 of the flexible screen 200 are flush; the folded state refers to the state when the first shell 310 and the second shell 320 are completely folded with each other, which can also be understood as the state when the two non-bending areas 220 on both sides of the bendable area 210 in the flexible screen 200 are close to each other.
当可折叠电子设备600折叠时，第一壳体310与第二壳体320相互折叠，第一支撑板331与第二支撑板332相互折叠；当可折叠电子设备600展开时，第一壳体310与第二壳体320相互展开，第一支撑板331与第二支撑板332相互展开。换句话说，当可折叠电子设备600折叠时，两个壳体先进行折叠，随后带动两个支撑板相互折叠，最终使柔性屏200中可弯折区210两侧的两个非弯折区220相互靠近；当可折叠电子设备600折叠展开时，两个壳体先展开，随后带动两个支撑板相互展开，最终使柔性屏200中可弯折区210两侧的两个非弯折区220相互展开。对于上述可折叠电子设备600在折叠与展开时具有多种主动从动关系，本实施方式将详细介绍其中一种具体的实现方式。When the foldable electronic device 600 is folded, the first shell 310 and the second shell 320 are folded with each other, and the first support plate 331 and the second support plate 332 are folded with each other; when the foldable electronic device 600 is unfolded, the first shell 310 and the second shell 320 are unfolded with each other, and the first support plate 331 and the second support plate 332 are unfolded with each other. In other words, when the foldable electronic device 600 is folded, the two shells are folded first, and then the two support plates are driven to fold with each other, and finally the two non-bending areas 220 on both sides of the bendable area 210 in the flexible screen 200 are close to each other; when the foldable electronic device 600 is folded and unfolded, the two shells are unfolded first, and then the two support plates are driven to unfold with each other, and finally the two non-bending areas 220 on both sides of the bendable area 210 in the flexible screen 200 are unfolded with each other. For the above-mentioned foldable electronic device 600 having multiple active and passive relationships when folding and unfolding, this embodiment will introduce one of the specific implementation methods in detail.
当可折叠电子设备600欲从展开状态至折叠状态时，即可折叠电子设备600需要进行弯折时，此时需朝可折叠电子设备600的中心推动或拉拽第一壳体310及第二壳体320，便可让第一壳体310及第二壳体320进行转动，第一壳体310及第二壳体320转动的过程中便可带动第一壳体310及第二壳体320相对折叠结构334转动，使第一壳体310及第二壳体320相互靠近，使柔性屏200中可弯折区210两侧的两个非弯折区220相互靠近实现可折叠电子设备600的折叠。当可折叠电子设备600需要从折叠状态回归到展开状态时，只需要向外拽第一壳体310，使第一壳体310与第二壳体320进行反向转动，带动第一壳体310及第二壳体320相对折叠结构334反向转动，使第一壳体310及第二壳体320相互远离，最终使柔性屏200中可弯折区210两侧的两个非弯折区220相互展开，柔性屏200也重新恢复到可弯折区210和非弯折区220表面齐平的状态。When the foldable electronic device 600 is to bend from an unfolded state to a folded state, that is, the foldable electronic device 600 needs to be bent, the first shell 310 and the second shell 320 need to be pushed or pulled toward the center of the foldable electronic device 600 to rotate the first shell 310 and the second shell 320. During the rotation of the first shell 310 and the second shell 320, the first shell 310 and the second shell 320 can be driven to rotate relative to the folding structure 334, so that the first shell 310 and the second shell 320 are close to each other, and the two non-bending areas 220 on both sides of the bendable area 210 in the flexible screen 200 are close to each other to achieve the folding of the foldable electronic device 600. When the foldable electronic device 600 needs to return to the unfolded state from the folded state, it only needs to pull the first shell 310 outward to make the first shell 310 and the second shell 320 rotate in the opposite direction, thereby driving the first shell 310 and the second shell 320 to rotate in the opposite direction relative to the folding structure 334, so that the first shell 310 and the second shell 320 move away from each other, and finally make the two non-bending areas 220 on both sides of the bendable area 210 in the flexible screen 200 unfold to each other, and the flexible screen 200 also returns to the state where the surfaces of the bendable area 210 and the non-bending area 220 are flush.
在本申请一实施方式中，可折叠电子设备600还包括第一缓冲件，第一缓冲件设置在第三支撑板333和柔性屏200之间。第一缓冲件用于连接第三支撑板333和柔性屏200，并在可折叠电子设备600折叠、展开过程中起到一定的缓冲作用。在本申请一实施方式中，可折叠电子设备600还包括第二缓冲件，第二缓冲件设置在第一中框312和柔性屏200之间，和/或第二中框322和柔性屏200之间。第二缓冲件用于连接中框和柔性屏200，并在可折叠电子设备600折叠、展开过程中起到一定的缓冲作用。在一实施例中，第二缓冲件设置在第一中框312和柔性屏200之间，以及设置在第二中框322和柔性屏200之间。进一步的，多个第二缓冲件对称设置。在本申请中，第一缓冲件和第二缓冲件的材质可以根据需要进行选择，例如可以但不限于为泡棉、胶黏剂等。在一实施例中，第一缓冲件可以为泡棉，第二缓冲件可以为胶黏剂层。在一实施例中，第一缓冲件和第二缓冲件与柔性屏200的支撑片连接。当然，在其他可实现方式中，第一中框312和/或第二中框322可以与柔性屏200直接贴合设置。In one embodiment of the present application, the foldable electronic device 600 further includes a first buffer, which is arranged between the third support plate 333 and the flexible screen 200. The first buffer is used to connect the third support plate 333 and the flexible screen 200, and plays a certain buffering role during the folding and unfolding of the foldable electronic device 600. In one embodiment of the present application, the foldable electronic device 600 further includes a second buffer, which is arranged between the first middle frame 312 and the flexible screen 200, and/or between the second middle frame 322 and the flexible screen 200. The second buffer is used to connect the middle frame and the flexible screen 200, and plays a certain buffering role during the folding and unfolding of the foldable electronic device 600. In one embodiment, the second buffer is arranged between the first middle frame 312 and the flexible screen 200, and between the second middle frame 322 and the flexible screen 200. Further, multiple second buffers are arranged symmetrically. In the present application, the material of the first buffer and the second buffer can be selected as needed, for example, it can be but not limited to foam, adhesive, etc. In one embodiment, the first buffer can be foam, and the second buffer can be an adhesive layer. In one embodiment, the first buffer and the second buffer are connected to the support sheet of the flexible screen 200. Of course, in other possible implementations, the first middle frame 312 and/or the second middle frame 322 can be directly attached to the flexible screen 200.
请参阅图5，为相关技术中可折叠电子设备的部分截面示意图，相关技术中可折叠电子设备700折叠、展开时第一中框705、第二中框706和柔性屏701的非弯折区220之间的间距固定；转轴组件330通过胶层707与柔性屏701连接。胶层707可以设置在第一支撑板702与柔性屏701之间，也可以设置 在第二支撑板704与柔性屏701之间，还可以设置在第一支撑板702、第二支撑板704与柔性屏701之间。由于转轴组件330对应于柔性屏701的可弯折区210，从而在可折叠电子设备700折叠、展开时转轴组件330与柔性屏701之间的间距发生变化，转轴组件330中的第一支撑板702、第二支撑板704和第三支撑板703与柔性屏701之间的间距不匹配，同时与第一中框705、第二中框706和柔性屏701之间间距也不匹配，从而导致可折叠电子设备700的折痕明显。同时，第一支撑板702和第二支撑板704长度较大，而且第一支撑板702和第二支撑板704表面不平整，在可折叠电子设备700折叠、展开过程中会反馈到柔性屏701，使柔性屏701产生折痕或凌乱的光影，影响可折叠电子设备700的使用。Please refer to Figure 5, which is a partial cross-sectional diagram of a foldable electronic device in the related art. When the foldable electronic device 700 in the related art is folded or unfolded, the spacing between the first middle frame 705, the second middle frame 706 and the non-bending area 220 of the flexible screen 701 is fixed; the hinge assembly 330 is connected to the flexible screen 701 through the adhesive layer 707. The adhesive layer 707 can be set between the first support plate 702 and the flexible screen 701, and can also be set It can also be arranged between the second support plate 704 and the flexible screen 701, or between the first support plate 702, the second support plate 704 and the flexible screen 701. Since the hinge assembly 330 corresponds to the bendable area 210 of the flexible screen 701, the spacing between the hinge assembly 330 and the flexible screen 701 changes when the foldable electronic device 700 is folded and unfolded, and the spacing between the first support plate 702, the second support plate 704 and the third support plate 703 in the hinge assembly 330 and the flexible screen 701 does not match, and the spacing between the first middle frame 705, the second middle frame 706 and the flexible screen 701 does not match, resulting in obvious creases in the foldable electronic device 700. At the same time, the first support plate 702 and the second support plate 704 are relatively long, and the surfaces of the first support plate 702 and the second support plate 704 are uneven, which will be fed back to the flexible screen 701 during the folding and unfolding process of the foldable electronic device 700, causing creases or messy light and shadows on the flexible screen 701, affecting the use of the foldable electronic device 700.
因此，本申请提供了一种连接组件100，用于可折叠电子设备600中，设置在柔性屏200和转轴组件330之间，用于连接柔性屏200和转轴组件330。连接组件100包括基材30、第一连接件10和第二连接件20，基材30包括相连的第一部31和第二部32，基材30具有相背设置的第一表面36和第二表面37，第一连接件10设置在第一部31的第一表面36，第二连接件20设置在第二部32的第二表面37，连接组件100受力时第一部31能够相对第二部32发生弹性形变，以调节连接组件100在第一连接件10、基材30及第二连接件20的层叠方向上的厚度。Therefore, the present application provides a connection component 100, which is used in a foldable electronic device 600, and is arranged between a flexible screen 200 and a hinge assembly 330, and is used to connect the flexible screen 200 and the hinge assembly 330. The connection component 100 includes a substrate 30, a first connection member 10, and a second connection member 20. The substrate 30 includes a first portion 31 and a second portion 32 connected to each other. The substrate 30 has a first surface 36 and a second surface 37 that are arranged opposite to each other. The first connection member 10 is arranged on the first surface 36 of the first portion 31, and the second connection member 20 is arranged on the second surface 37 of the second portion 32. When the connection component 100 is subjected to force, the first portion 31 can be elastically deformed relative to the second portion 32 to adjust the thickness of the connection component 100 in the stacking direction of the first connection member 10, the substrate 30, and the second connection member 20.
本申请提供的连接组件100受力时，第一部31能够相对第二部32发生弹性形变以及基材30发生弹性形变，以调节连接组件100在厚度方向上的尺寸(即连接组件100的厚度)，从而导致连接组件100的厚度发生变化。也就是说，当连接组件100受到作用力时，该外力在厚度方向上产生作用，使得第一部31能够相对第二部32发生弹性形变以及基材30发生弹性形变，从而可以改变连接组件100的厚度，其中外力与厚度方向平行或大致平行，只要在沿厚度方向上具有作用效果即可。因此，当连接组件100设置在柔性屏200和转轴组件330之间时，连接组件100的厚度即为柔性屏200与转轴组件330之间的间距，连接组件100发生弹性形变以使连接组件100的厚度匹配第一壳体310、第二壳体320与柔性屏200之间的间距，从而使可折叠电子设备600的折痕不明显。其中，匹配第一壳体310、第二壳体320与柔性屏200之间的间距是指当可折叠电子设备600展开时，壳体与柔性屏200之间的间距与连接组件100的厚度差距较小或相等，使得柔性屏200的表面处于同一水平面，保证柔性屏200的表面无明显凹陷或凸起，从而不会产生明显折痕，尤其是柔性屏200的可弯折区210的表面以及可弯折区210与非弯折区220连接的表面无明显折痕；当可折叠电子设备600折叠时，在折叠轴任意一侧的柔性屏200表面处于同一水平面，使柔性屏200表面无明显凹陷或凸起，从而不会产生明显折痕，优化可折叠电子设备600中柔性屏200表面的光影效果。When the connecting component 100 provided in the present application is subjected to force, the first part 31 can be elastically deformed relative to the second part 32 and the substrate 30 can be elastically deformed to adjust the size of the connecting component 100 in the thickness direction (i.e., the thickness of the connecting component 100), thereby causing the thickness of the connecting component 100 to change. That is, when the connecting component 100 is subjected to an external force, the external force acts in the thickness direction, so that the first part 31 can be elastically deformed relative to the second part 32 and the substrate 30 can be elastically deformed, thereby changing the thickness of the connecting component 100, wherein the external force is parallel or approximately parallel to the thickness direction, as long as it has an effect along the thickness direction. Therefore, when the connecting component 100 is arranged between the flexible screen 200 and the rotating shaft component 330, the thickness of the connecting component 100 is the spacing between the flexible screen 200 and the rotating shaft component 330, and the connecting component 100 is elastically deformed so that the thickness of the connecting component 100 matches the spacing between the first shell 310, the second shell 320 and the flexible screen 200, so that the folding mark of the foldable electronic device 600 is not obvious. Among them, matching the distance between the first shell 310, the second shell 320 and the flexible screen 200 means that when the foldable electronic device 600 is unfolded, the distance between the shell and the flexible screen 200 is smaller than or equal to the thickness of the connecting component 100, so that the surface of the flexible screen 200 is in the same horizontal plane, ensuring that there are no obvious depressions or protrusions on the surface of the flexible screen 200, thereby no obvious creases are produced, especially the surface of the bendable area 210 of the flexible screen 200 and the surface connecting the bendable area 210 and the non-bending area 220 have no obvious creases; when the foldable electronic device 600 is folded, the surface of the flexible screen 200 on either side of the folding axis is in the same horizontal plane, so that there are no obvious depressions or protrusions on the surface of the flexible screen 200, thereby no obvious creases are produced, thereby optimizing the light and shadow effects on the surface of the flexible screen 200 in the foldable electronic device 600.

请参阅图10为图6中A-A方向上的截面图，第二连接件20环绕第一连接件10的外周设置，第二连接件20围设形成容置空间21。请参阅图11，为图10所示的连接组件受力后的示意图，当第一连接件10与第二连接件20受到相向的力时，第一部31能够相对第二部32发生弹性形变，以减小沿层叠方向上的连接组件100的厚度。该力可以平行或大致平行层叠方向，只要在平行层叠方向上具有作用效果即可；由于基材30的第一部31未设置第二连接件20，第二部32未设置第一连接件10，从而在受力时第一部31能够相对第二部32发生弹性形变，进而改变在受力范围内连接组件100的厚度，即如图10所示的连接组件100厚度为H，图11中基材30发生弹性形变，最大形变量为h2，使得连接组件100的厚度减小且最小厚度为h1，即受力后基材30弹性形变导致连接组件100的厚度发生变化。在一实施例中，当第一连接件10与第二连接件20受到相向的力时，至少部分第一部31嵌设于容置空间21中，以减小沿层叠方向上的连接组件100的厚度；在另一实施例中，当第一连接件10与第二连接件20受到沿层叠方向上相向的力时，第一部31与第一连接件10中的至少部分嵌设于容置空间21中，如此可以减小沿层叠方向上的连接组件100的厚度。如此有利于加大第一部31的弹性形变范围，进一步降低连接组件100的厚度，有利于其在可折叠电子设备600中进一步改善折痕效果并提升柔性屏200表面光影效果。Please refer to Fig. 10, which is a cross-sectional view along the A-A direction in Fig. 6. The second connecting member 20 is arranged around the outer periphery of the first connecting member 10, and the second connecting member 20 is arranged to form an accommodating space 21. Please refer to Fig. 11, which is a schematic diagram of the connecting assembly shown in Fig. 10 after being subjected to force. When the first connecting member 10 and the second connecting member 20 are subjected to opposite forces, the first portion 31 can be elastically deformed relative to the second portion 32 to reduce the thickness of the connecting assembly 100 along the stacking direction. The force can be parallel or approximately parallel to the stacking direction, as long as it has an effect in the parallel stacking direction; since the first part 31 of the substrate 30 is not provided with the second connecting member 20, and the second part 32 is not provided with the first connecting member 10, the first part 31 can undergo elastic deformation relative to the second part 32 when subjected to force, thereby changing the thickness of the connecting component 100 within the force range, that is, the thickness of the connecting component 100 shown in Figure 10 is H, and the substrate 30 in Figure 11 undergoes elastic deformation, the maximum deformation is h2, so that the thickness of the connecting component 100 is reduced and the minimum thickness is h1, that is, the elastic deformation of the substrate 30 after being subjected to force causes the thickness of the connecting component 100 to change. In one embodiment, when the first connector 10 and the second connector 20 are subjected to opposite forces, at least part of the first portion 31 is embedded in the accommodating space 21 to reduce the thickness of the connecting component 100 along the stacking direction; in another embodiment, when the first connector 10 and the second connector 20 are subjected to opposite forces along the stacking direction, at least part of the first portion 31 and the first connector 10 are embedded in the accommodating space 21, so that the thickness of the connecting component 100 along the stacking direction can be reduced. This is conducive to increasing the elastic deformation range of the first portion 31, further reducing the thickness of the connecting component 100, and is conducive to further improving the crease effect in the foldable electronic device 600 and enhancing the light and shadow effect on the surface of the flexible screen 200.

In one embodiment, the ratio of the area of the overlapping area to the area of the first projection is less than or equal to 10%, and the ratio of the area of the overlapping area to the area of the second projection is less than or equal to 10%. This is further conducive to the elastic deformation of the substrate 30.

For example, the vertical direction in FIG. 17 is the thickness direction mentioned above, and it can be understood that the thickness direction is the stacking direction. Since at least part of the first portion 31 is raised relative to the second portion 32 in the direction toward the second surface 37, the substrate 30 has a non-flat surface, so that after the first connector 10 and the second connector 20 are arranged, the flatness of the two surfaces of the connection component 100 relative to each other in the thickness direction can be effectively improved, and the protruding first portion 31 can increase its elastic deformation ability. Therefore, when the connection component 100 is arranged between the flexible screen 200 and the hinge component 330, the surface flatness of the connection component 100 itself is high, so that the crease problem of the foldable electronic device 600 can be further improved, and the light and shadow effect and flatness of the surface of the flexible screen 200 in the foldable electronic device 600 can be optimized.

The connection assembly 100 includes a substrate 30, a first connection member 10, and a second connection member 20. The substrate 30 includes a first portion 31 and a second portion 32 connected to each other. The first portion 31 can be elastically deformed relative to the second portion 32. The substrate 30 has at least one first hollow portion 33. The extension direction of the first hollow portion 33 is at least one of a broken line shape and a curved line shape. The first connection member 10 is arranged on the surface of the first portion 31; the second connection member 20 is arranged on the surface of the second portion 32 away from the first connection member 10. When the substrate 30 has one or more first hollow portions 33 extending in a fold line and/or a curve, the substrate 30 near the first hollow portion 33 can be deformed according to the magnitude of the external force, so that on the basis of the overall deformation of the substrate 30, the inside of the substrate 30 is also deformed at the same time to improve the thickness of the connecting component 100. In addition, compared with the straight-line extension, the first hollow portion 33 extending in a fold line and/or a curve can make the positions of the substrate 30 near the first hollow portion 33 staggered with each other, so that the substrate 30 at different positions undergoes separate deformation according to the force conditions, thereby changing the thickness of the connecting component 100 at different force positions, and further optimizing the thickness of the connecting component 100. The substrate 30 in the connecting component 100 is provided with a first hollow portion 33, and the substrate 30 near the first hollow portion 33 can further optimize the deformation so that the thickness of the connecting component 100 better matches the spacing between the first shell 310, the second shell 320 and the flexible screen 200, thereby improving the crease problem of the foldable electronic device 600 and optimizing the light and shadow effect and flatness of the surface of the flexible screen 200 in the foldable electronic device 600.

In one embodiment of the present application, the second portion 32 is disposed around the periphery of the entire first portion 31; that is, the second portion 32 is disposed around the first portion 31 and is in a surrounding shape. Please refer to FIG. 29 , which is a cross-sectional view in the F-F direction of FIG. 26 , in which the second portion 32 is disposed around the periphery of the first portion 31. In one embodiment, the second portion 32 is disposed around the first portion 31 and is in a surrounding shape, and the second connector 20 is surrounded to form a receiving space 21. For example, when the first connector 10 and the second connector 20 are subjected to opposing forces, at least a portion of the first portion 31 is embedded in the receiving space 21 to reduce the thickness of the connecting assembly 100 along the stacking direction. The force can be parallel or substantially parallel to the stacking direction, as long as it has an effect in the parallel stacking direction. This can reduce the thickness of the connecting component 100 along the stacking direction, which is beneficial to increasing the elastic deformation range of the first part 31 and further reducing the thickness of the connecting component 100, which is beneficial to further improve the creases in the foldable electronic device 600 and enhance the light and shadow effects on the surface of the flexible screen 200.

During the folding and unfolding process of the foldable electronic device 600, there is a step difference between the spacing between the first shell 310, the second shell 320 and the flexible screen 200 and the spacing between the third support plate 333 and the flexible screen 200, which will cause the foldable electronic device 600 to have obvious creases. The connection component 100 provided in the present application is arranged between the first support plate 331 and/or the second support plate 332 and the flexible screen 200, and the height can be adjusted adaptively, thereby eliminating the crease problem caused by the step difference; at the same time, when the first support plate 331 and/or the second support plate 332 are in direct contact with the flexible screen 200, pits will be generated on the surface of the first support plate 331 and/or the second support plate 332 during the use of the foldable electronic device 600, making the flexible screen 200 crease obvious, and the connection component 100 provided in the present application can eliminate the above-mentioned influence and improve the light and shadow effect on the surface of the flexible screen 200. In one embodiment of the present application, the first connector 10 is arranged between the substrate 30 and the flexible screen 200. In another embodiment of the present application, the second connector 20 is arranged between the substrate 30 and the flexible screen 200.

In one embodiment, the connecting component 100 is connected to the support sheet in the flexible screen 200. Please refer to Figure 47, which is a schematic diagram of the structure of the connecting component and the hinge component provided in one embodiment of the present application.
