[0026] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] In the related art, flexible screens are increasingly applied to electronic devices such as mobile phones. By cooperating with the bent side of the electronic device housing, the display area and overall display effect of the flexible screen can be improved. However, the stress generated by the bending of the flexible screen increases the difficulty of assembling it with the electronic device housing, and the separation or damage of the screen from the electronic device housing due to excessive stress also occur from time to time.

[0028] For example Figure 1 As shown, the housing A1 of the electronic device A includes a planar region A11 and a bent region A12 connecting adjacent planar regions A11. Correspondingly, the flexible screen A2 includes an integral planar portion A21 and a bent portion A22. The planar portion A21 is attached to the planar region A11 of the housing A1 through an adhesive layer A3, and the bent portion A22 is attached to the bent region A12 of the housing A1 through an adhesive layer A3. During the cooperation between the flexible screen A2 and the housing A1, due to the large stress at the bent portion A22, the planar portion A21 near the bent portion A22 is subjected to a pulling force that causes it to separate from the housing A1. Therefore, the flexible screen A2 is at risk of falling off and screen damage, which also reduces the service life and user experience of the electronic device A.

[0029] Figure 2 is a schematic structural diagram of an electronic device proposed in an exemplary embodiment of the present disclosure. As Figure 2 shown, the electronic device 1 includes: an integral flexible screen assembly 12, a device housing 11, and a telescopic device 13. The device housing 11 includes a front surface 111, a back surface 112, and a bent side surface 113 connecting the front surface 111 and the back surface 112. The back surface 112 includes a reserved area 1122 and an assembly area 1121 connected thereto. Among them, the assembly area 1121 is the area on the back surface 112 covered by the flexible screen assembly 12, and is used to support and assemble the flexible screen assembly 12. The reserved area 1122 is the area on the back surface 112 not covered by the flexible screen assembly 12. The flexible screen assembly 12 covers the front surface 111, the bent side surface 113, and the assembly area 1121 of the back surface 112, and both ends of the display area of the flexible screen assembly 12 are respectively assembled and cooperated with both sides of the reserved area 1122. The telescopic device 13 is assembled in the device housing 11, and the flexible screen assembly 12 includes an extension layer 121 protruding from the display area, and the extension layer 121 is connected to the telescopic device 13.

[0030] In the above embodiments, the telescopic device 13 may correspond to the position of the reserved area 1122, so that the extension layer 121 of the flexible screen assembly 12 can be connected through the reserved area 1122. Alternatively, the telescopic device 1 may also be disposed at other positions inside the device housing 11, as long as the connection between the extension layer 121 and the telescopic device 13 can be achieved, and the present disclosure does not limit this.

[0031] By providing the telescopic device 13 inside the housing of the electronic device 1 and making the telescopic device 13 telescopically connected to the extension layer 121 of the flexible screen assembly 12, the telescopic device 13 pulls on the flexible screen assembly 12 during the assembly and use of the flexible screen assembly 12. On the one hand, the above structural arrangement can achieve assembly by pulling on the flexible screen assembly 12, avoiding the influence of the dimensional tolerance of the flexible screen assembly 12 on its fit with the housing of the electronic device 1; on the other hand, the pulling of the telescopic device 13 can also overcome the separation stress generated by the bending of the flexible screen assembly 12, improving the connection reliability between the flexible screen assembly 12 and the housing of the electronic device 1.

[0032] In the above embodiments, the electronic device 1 further includes an adhesive layer 14, and the flexible screen assembly 12 is fixedly connected to the device housing 11 through the adhesive layer 14. During the assembly of the electronic device 1, first, multiple layers such as the cover layer 122, display layer, and control layer of the flexible screen assembly 12 are glued together to form an integral body, and then the integral body of the flexible screen assembly 12 is fixed to the corresponding position of the device housing 11 through the adhesive layer 14. The above fixing method is convenient for operation and helps to reduce the assembly cost of the electronic device 1.

[0033] Further, the reserved area 1122 can be used to assemble other functional components such as the camera module and fingerprint recognition module of the electronic device 1, as the installation position of the flexible screen assembly 12, and as the appearance decoration position of the electronic device 1. Therefore, the reserved area 1122 can be set at a position on the back surface 112 close to the bending side surface 113 as shown in Figure 2 or at the central position of the back surface 112 as shown in Figure 3 , and the present disclosure does not limit this. When the reserved area 1122 is set at the central position of the back surface 112, the symmetry and aesthetics of the structure of the back surface 112 of the electronic device 1 can be improved. When the reserved area 1122 is set at a position on the back surface 112 close to the bending side surface 113, the single-sided coverage area of the flexible screen assembly 12 located on the back surface 112 is increased, the continuous screen ratio is improved, and the installation of functional components such as the camera is facilitated.

[0034] Based on the set position of the reserved area 1122 and the overall structure of the electronic device 1, an extension layer 121 can be selectively provided at at least one end of the flexible screen assembly 12, and the extension layer 121 is connected to the telescopic device 13. Specifically:

[0035] In one embodiment, as Figure 2 shown, when the reserved area 1122 is provided at a position on the back surface 112 close to the bending side surface 113, since the flexible screen assembly 12 close to the bending side surface 113 is subjected to a relatively large bending stress, an extension layer 121 can be provided at one end of the flexible screen assembly 12 where the relatively large bending stress is applied as needed, and the extension layer 121 is connected to the corresponding telescopic device 13. The above structural arrangement provides a reaction force for overcoming the bending stress to the flexible screen assembly 12 on this side. On the premise of ensuring the connection strength between the flexible screen assembly 12 and the housing of the electronic device 1, it not only simplifies the structure of the telescopic device 13, reduces its occupation of the internal space of the electronic device 1, but also reduces the structural improvement of the flexible screen assembly 12.

[0036] In another embodiment, as Figure 3 shown, when the reserved area 1122 is provided at the central position of the back surface 112, the stresses generated by the two bending side surfaces 113 on the electronic device 1 on the flexible screen assembly 12 are almost the same. Therefore, extension layers 121 can be provided at both ends of the flexible screen assembly 12 as needed, and the two extension layers 121 are respectively connected to the corresponding telescopic devices 13. The above structural arrangement provides a reaction force for overcoming the bending stress to the flexible screen assemblies 12 on both sides of the reserved area 1122, and avoids the detachment and damage of the flexible screen assembly 12.

[0037] In the above embodiments, the extension layer 121 can be formed by extending at least one of the cover layer 122, the display layer, and the control layer of the flexible screen assembly 12. For example, when the extension layer 121 is formed by extending the cover layer 122, the free end of the extension layer 121 is connected to the telescopic device 13, so that a pulling relationship can be formed with its cover layer 122 when the flexible screen assembly 12 is bent and strained. Among them, the material of the cover layer 122 can be PI (Polyimide) material, or can be composed of other materials, and the present disclosure does not limit this. Or, when the extension layer 121 is formed by extending the display layer, the control layer, etc. below the cover layer 122, its free end can still be connected to the telescopic device 13 to utilize the telescopic performance of the telescopic device 13 to form a pulling relationship with its display layer, control layer, etc. when the flexible screen assembly 12 is bent and strained.

[0038] Regardless of whether the extension layer 121 is formed by extending the cover plate layer 122, the display layer, or the control layer of the flexible screen assembly 12, its connection relationship with the telescopic device 13 is the same. Taking the extension layer 121 extending from the cover plate layer 122 as an example, the cooperation relationship between the extension layer 121 and the telescopic device 13 will be exemplarily described as follows:

[0039] In an embodiment, as Figure 3 shown, the telescopic device 13 includes an elastic member 131. The elastic member 131 is assembled on the middle shell of the device, on the bracket 15 inside the device housing 11, or can also be directly assembled and cooperated with the inner side surface of the device housing 11. The present disclosure does not limit this. Among them, in the width direction of the electronic device 1, the installation position of the elastic member 131 on the bracket 15 or the inner side surface of the device housing 11 may have a preset interval d from the end of the display area connected to the extension layer 121, so that the extension layer 121 forms an acute angle with the assembly surface of the elastic member 131, thereby enhancing the pulling effect of the elastic member 131 on the extension layer 121. It should be noted that the bracket 15 can be arranged at a position close to the back surface 112, or can also be arranged in the middle in the thickness direction of the electronic device 1. The present disclosure does not limit this. The elastic member 131 is connected to the free end of the extension layer 121. Through the direct connection between the elastic member 131 and the free end of the extension layer 121, the elastic force of the elastic member 131 is involved with the extension layer 121. Taking the example that one side of the flexible screen assembly 12 is provided with an extension layer 121, when assembling the flexible screen assembly 12, first connect the extension layer 121 of the flexible screen assembly 12 with the elastic member 131, and then bypass the assembly area 1121, the bending side 113, and the front surface 111 of the flexible screen assembly 12, and wind back to the other assembly area 1121 on the other side of the back surface 112. At this time, pull the flexible screen assembly 12. By using the elasticity of the elastic member 131, the two ends of the display area of the flexible screen assembly 12 are respectively aligned with the two sides of the reserved area 1122, and then the flexible screen assembly 12 is fixed on the device housing 11 through the bonding layer 14, avoiding the fitting error between the flexible screen assembly 12 and the housing of the electronic device 1 caused by the dimensional tolerance of the flexible screen assembly 12, and improving the assembly accuracy. And when using the electronic device 1 including the above flexible screen assembly 12, since one end of the flexible screen assembly 12 is connected to the telescopic device 13, the risk of the flexible screen assembly 12 falling off due to the bending stress generated by the corresponding bending side 113 is avoided, and the service life of the flexible screen assembly 12 and the electronic device 1 is improved.

[0040] Specifically, an assembly hole (not labeled) is provided at the free end of the extension layer 121, and the extension layer 121 is connected to the elastic member 131 through the assembly hole. By providing the assembly hole at the free end of the extension layer 121 and connecting it to the elastic member 131, the structure is simple, and the connection strength between the extension layer 121 and the elastic member 131 is ensured. Alternatively, the extension layer 121 can also be connected to the elastic member 131 by means of snap connection or the like, and the present disclosure does not limit this.

[0041] In another embodiment, as Figure 4 shown, the telescopic device 13 includes an elastic member 131 and a rotating member 132. The rotating member 132 is connected to the elastic member 131 in the rotating direction. The extension layer 121 is fixedly connected to the rotating member 132. Through the cooperation of the rotating member 132 and the elastic member 131, the rotating member 132 and the extension layer 121 are pulled. Similarly, taking the example that one side of the flexible screen assembly 12 is provided with an extension layer 121, when assembling the flexible screen assembly 12, first fixedly connect the extension layer 121 of the flexible screen assembly 12 to the rotating member 132, and then bypass the assembly area 1121, the bending side 113 and the front side 111 of the flexible screen assembly 12, and wrap back to the other assembly area 1121 on the other side of the back side 112. At this time, pull the flexible screen assembly 12, and the rotating member 132 elastically rotates due to the elastic force of the elastic member 131. Using the above elastic force, the two ends of the display area of the flexible screen assembly 12 are aligned with the two sides of the reserved area 1122 respectively, and then the flexible screen assembly 12 is fixed on the device housing 11 through the adhesive layer 14, avoiding the matching error between the flexible screen assembly 12 and the housing of the electronic device 1 due to the dimensional tolerance of the flexible screen assembly 12, and improving the assembly accuracy. And when using the electronic device 1 including the above flexible screen assembly 12, since one end of the flexible screen assembly 12 is connected to the telescopic device 13, the risk of the flexible screen assembly 12 falling off due to the bending stress generated by the corresponding bending side 113 is avoided, and the service life of the flexible screen assembly 12 and the electronic device 1 is improved.

[0042] In the above embodiment, since the reserved area 1122 is the part on the back side 112 of the device housing 11 that is not covered by the flexible screen assembly 12, pores can be provided in the reserved area 1122 to facilitate the extension layer 121 of the flexible screen assembly 12 to extend into the device housing 11 from the pores and cooperate with the telescopic device 13. In addition, functional components such as cameras, fingerprint recognition modules, and flashlights can also be assembled on the reserved area 1122, and the present disclosure does not limit this.

[0043] As Figure 5As shown, the extension layer 121 is indirectly connected to the elastic member 131 through the rotating member 132. Therefore, the rotating member 132 can play a buffering role and improve the stability of the displacement generated by the extension layer 121. Specifically, the rotating member 132 may include a circular edge, and a groove (not labeled) is provided on the circular edge. The extension layer 121 is wound in the groove, making the assembly relationship between the two more stable. A mating portion 1321 is provided on the rotating member 132, and the free end of the extension layer 121 is in interference fit with the mating portion 1321. This structural setting avoids the structural improvement and damage to the extension layer 121. Among them, the mating portion 1321 may be a hole structure provided on the rotating member 132. The free end of the extension layer 121 extends into the hole structure and is in interference fit with it, thereby realizing the fixation of the extension layer 121 and the rotating member 132. When assembling the flexible screen assembly 12 or when the flexible screen assembly 12 is subjected to bending stress, the extension layer 121 is subjected to tension, and the rotating member 132 rotates or has a tendency to rotate. The elastic force of the elastic member 131 gives a reaction force to the rotating member 132 along the rotation direction. Therefore, it helps to improve the assembly accuracy and connection reliability between the flexible screen assembly 12 and the housing of the electronic device 1.

[0044] It should be noted that there may be one or more elastic members 131, and the present disclosure does not limit this. When there are two elastic members 131, they can be symmetrically arranged at opposite ends of the rotating member 132 to provide elastic forces to overcome stress or tension from symmetric orientations, improving the tensile effect of the extension layer 121.

[0045] By providing a telescopic device 13 inside the housing of the electronic device 1 and elastically connecting the telescopic device 13 to the extension layer 121 of the flexible screen assembly 12, the telescopic device 13 elastically pulls the flexible screen assembly 12 during the assembly and use of the flexible screen assembly 12. The above structural setting can, on the one hand, achieve assembly by pulling the flexible screen assembly 12 and avoid the influence of the dimensional tolerance of the flexible screen assembly 12 on its fit with the housing of the electronic device 1; on the other hand, the elastic pull of the telescopic device 13 can also overcome the separation stress generated by the bending of the flexible screen assembly 12 and improve the connection reliability between the flexible screen assembly 12 and the housing of the electronic device 1.

[0046] It should be noted that the electronic device 1 may be a mobile phone, a tablet computer, a vehicle-mounted device, a medical terminal, etc., and the present disclosure does not limit this.
