[0002] Competition in the mobile terminal industry is increasingly trending towards large screens and ultra-thin devices, but large screens make the entire device too large and inconvenient to carry. Foldable electronic devices can solve the above problem by changing the size of the electronic device due to their folding function, and are now popular with a large number of users. However, the flexible screen in an electronic device will produce creases after multiple foldings, and the creases are deep. Summary of the invention
[0003] In view of this, the first aspect of the present application provides a support member applied to a folding device, wherein the folding device comprises two carriers arranged at an interval, and the support member is used to be arranged on one side of the two carriers, and the support member comprises:
[0004] A supporting portion, at least a portion of which is used to correspond to the gap between the two carriers when the folding device is in an unfolded state;
[0005] two bending portions, the two bending portions being disposed at opposite sides of the supporting portion, and the rigidity of the bending portions being smaller than the rigidity of the supporting portion; and
[0006] Two fixing parts, one fixing part is arranged on a side of one bending part away from the supporting part and is used to be fixed to one bearing member, and the other fixing part is arranged on a side of the other bending part away from the supporting part and is used to be fixed to the other bearing member.
[0007] The support member provided in the first aspect of the present application is designed to have the middle of the support member as a support portion, and a bending portion and a fixing portion are respectively arranged on opposite sides of the support portion, and the bending portion is closer to the support portion than the fixing portion. The two fixing portions are respectively fixed to the two bearing members to realize the subsequent fixing of the support member. The two bending portions with smaller rigidity, that is, larger elasticity, can realize the bending of the support member with the bearing member. And the present application makes at least part of the support portion with larger rigidity correspond to the gap between the two bearing members when the folding device is in the unfolded state. In other words, when the folding state is in the unfolded state, the two bearing members are flattened and arranged, and there is a gap between the two bearing members, and at least part of the support portion corresponds to the gap. When the folding device is applied to an electronic device and folded, in the related art, the flexible screen does not have sufficient support at the gap between the two bearing members, so the crease is deeper and the peak and trough difference is larger. The present application uses a support portion with larger rigidity to block the gap between the two bearing members, so the flexible screen corresponding to the gap should have a peak upwardly pushed out of the deepest crease, the crease becomes shallower, and the peak and trough creases fluctuate relatively slowly, thereby improving the crease produced by the flexible screen.

[0009] The folding device provided in the second aspect of the present application, by adopting the support member provided in the first aspect of the present application, can improve the creases produced by the flexible screen when subsequently applied to an electronic device.
[0010] A third aspect of the present application provides a shell assembly, which includes a first shell, a second shell, and a folding device as provided in the second aspect of the present application, and the folding device is connected between the first shell and the second shell.
[0011] The shell assembly provided in the third aspect of the present application, by adopting the folding device provided in the second aspect of the present application, can improve the creases produced by the flexible screen when subsequently applied to an electronic device.
[0012] The fourth aspect of the present application provides an electronic device, which includes a flexible screen and a shell assembly as provided in the third aspect of the present application, wherein the flexible screen is arranged on the same side of the first shell, the second shell, and the folding device, the supporting member of the shell assembly is fixed to the flexible screen, and at least a portion of the supporting member of the shell assembly abuts against the flexible screen.
[0013] The electronic device provided in the fourth aspect of the present application can improve the creases produced by the flexible screen by adopting the shell assembly provided in the third aspect of the present application, thereby increasing the service life of the flexible screen and the use effect of the electronic device.

DETAILED DESCRIPTION
[0032] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.
[0033] Competition in the mobile terminal industry is increasingly trending towards large screens and ultra-thin devices, but large screens make the entire device too large and inconvenient to carry. Foldable electronic devices can solve the above problem by changing the size of the electronic device due to their folding function, and are now very popular with users. The folding device of an electronic device usually includes two carrier plates arranged at intervals, and the flexible screen is arranged on the two carrier plates and uses the two carrier plates to achieve a water drop shape or a U-shaped shape of the flexible screen when folded. Due to the characteristics of the flexible screen, the glue in the screen will creep after the flexible screen is folded for a long time, resulting in a downward concave crease at the bend. Because the flexible screen does not have sufficient support in the gap between the two carrier plates, the crease is relatively deep, and the difference between the peaks and troughs is large.
[0034] At present, some people use a three-plate solution to replace the two-plate solution, that is, in addition to the two carriers, a third carrier plate is provided between the two carrier plates, so as to realize the teardrop-shaped flexible screen folding form. Although the crease of the flexible screen can be improved to a certain extent by providing a third carrier plate in the gap between the two carrier plates, the width of the three-plate folding device is larger than that of the two-plate folding device, which is not conducive to the space utilization inside the electronic device. In addition, the number of parts of the three-plate folding device is also more than that of the two-plate shaft, and the processing / assembly of the folding device is relatively difficult and the cost is relatively high.
[0035] In view of this, in order to solve the above problems, this application provides a support member. Please refer to Figure 1-Figure 9 The support member 1 of this embodiment is applied to a folding device 2, the folding device 2 includes two carriers 40 arranged at intervals, the support member 1 is used to be arranged on one side of the two carriers 40, and the support member 1 includes a support portion 10, two bending portions 20, and two fixing portions 30. At least a portion of the support portion 10 is used to correspond to the gap 41 between the two carriers 40 when the folding device 2 is in an unfolded state. The two bending portions 20 are arranged on opposite sides of the support portion 10, and the rigidity of the bending portion 20 is less than the rigidity of the support portion 10. One of the fixing portions 30 is arranged on a side of one of the bending portions 20 away from the support portion 10 and is used to be fixed to one of the carriers 40, and the other fixing portion 30 is arranged on a side of the other bending portion 20 away from the support portion 10 and is used to be fixed to the other of the carriers 40.
[0036] When the support member 1 is applied to the folding device 2, the folding device 2 can support the flexible screen 50 when it is applied to the electronic device 4. For example, the folding device 2 includes two carriers 40 arranged at intervals, that is, the folding device 2 is a two-plate rotating shaft. The support member 1 can be arranged on one side of the two carriers 40 and span the gap 41 between the two carriers 40, so that the flexible screen 50 is supported by the support member 1 and the two carriers 40. The support member 1 includes a support portion 10, two bending portions 20, and two fixing portions 30. The support member 1 of this embodiment is composed of the support portion 10, two bending portions 20, and two fixing portions 30. Of course, in other embodiments, the support member 1 may also include other parts. The bending portions 20 and the fixing portions 30 are respectively arranged on opposite sides of the support portion 10. In other words, the bending portion 20 located on the same side of the support portion 10 is closer to the support portion 10 than the fixing portion 30. Specifically, the opposite sides of the bending portion 20 are connected to the support portion 10 and the fixing portion 30 respectively. The support part 10, the two bending parts 20, and the two fixing parts 30 may also be an integrated structure or a split structure. This embodiment is only schematically described with the support part 10, the two bending parts 20, and the two fixing parts 30 as an integrated structure. Optionally, the material of the support member 1 includes but is not limited to metal and carbon fiber.
[0037] The two fixing portions 30 are respectively fixed to the two carriers 40, for example, one fixing portion 30 is fixed to one carrier 40, and the other fixing portion 30 is fixed to the other carrier 40, so as to realize the fixation of the support member 1 and the folding device 2 and realize the cross-gap support of the middle gap 41 of the folding device 2. Optionally, the fixing portion 30 can be fixed to the carrier 40 by bonding, snap connection, screw connection, etc. Optionally, in the arrangement direction of the two carriers 40, the fixing portion 30 can cover and block the carrier 40. At this time, the carrier 40 is actually in contact with the flexible screen 50. Therefore, the fixing portion 30 also supports the flexible screen 50 and supports the bending stress generated after the flexible screen 50 is bent.
[0038] The rigidity of the two bending portions 20 is smaller than that of the supporting portion 10. In other words, the elasticity of the bending portions 20 is smaller and smaller than that of the supporting portion 10. The bending portions 20 are used for elastic stretching deformation in the bending state when the folding device 2 is folded and elastic recovery in the flattened state when unfolded. In other words, the arrangement of the bending portions 20 enables the supporting member 1 to bend along with the supporting member 40. Optionally, when the folding device 2 is in the unfolded state, at least part of the bending portions 20 is arranged corresponding to the supporting member 40. For example, the bending portions 20 may be arranged entirely corresponding to the supporting member 40, or part of the bending portions 20 may be arranged corresponding to the supporting member 40, and the remaining part may be arranged corresponding to the gap 41 between the two supporting members 40.
[0039] The support portion 10 located between the two bending portions 20 has a relatively large rigidity, and in this embodiment, at least a portion of the support portion 10 with a relatively large rigidity corresponds to the gap 41 between the two carriers 40 when the folding device 2 is in the unfolded state. In other words, when the folded state is in the unfolded state, the two carriers 40 are flattened and arranged, and there is a gap 41 between the two carriers 40, and at least a portion of the support portion 10 corresponds to the gap 41. For example, the entire support portion 10 is arranged to correspond to the gap 41, or a portion of the support portion 10 is arranged to correspond to the gap 41, and the remaining portion is arranged to correspond to the carrier 40. The positive correspondence mentioned here and later can be understood as at least a portion of the positive projection of the support portion 10 on the folding device 2 is located in the gap 41.
[0040] like Figure 6 As shown, in the related art, when the folding device 2 is applied to the electronic device 4 and folded, the two-plate folding device 2 has a deep crease and a large difference between the peak and the trough because the flexible screen 50 does not have sufficient support at the gap 41 between the two carriers 40. The gap 41 is the main reason for the poor crease. Figure 8 As shown, the support part 10 of this embodiment is located directly above the gap 41, whether it is partially or completely corresponding to the gap 41. At this time, the support part 10 with greater rigidity can also be understood as the third bearing member 40. Therefore, the two-plate folding device 2 can be transformed into a three-plate folding device 2 by setting the support member 1. The flexible screen 50 originally corresponding to the gap 41 can now abut the support part 10, so that a peak is pushed upward from the crease that should be the deepest, the crease becomes shallower, and the peak and trough creases fluctuate relatively slowly, thereby improving the crease produced by the flexible screen 50. In other words, the support part 10 plays a role of rigid support, which is equivalent to the role of the middle plate of the three-plate shaft holding up upward.
[0041] In summary, the support member 1 of this embodiment can be used in conjunction with the two-plate folding device 2, so that the two-plate folding device 2 can have a similar support effect as the three-plate folding device 2, thereby improving the creases produced by the folding screen, solving the user's pain point problem, and improving the user experience. In addition, since the support member 1 is disposed above the two carriers 40 as a whole, it does not increase the width of the folding device 2, which is conducive to the development of miniaturization of the folding device 2.
[0042] In this embodiment, the support portion 10 is used to have an orthographic projection on the folding device 2 covering the gap 41 between the two carriers 40 when the folding device 2 is in the unfolded state. In this embodiment, the support portion 10 can span the entire gap 41, that is, part of the support portion 10 corresponds to the gap 41, so that the flexible screen 50 corresponding to the gap 41 can be better supported to improve its folding effect.
[0043] Please refer again Figure 2-Figure 4In this embodiment, the support portion 10 has multiple rows of first through hole groups 11, each row of the first through hole group 11 includes multiple first through holes 110, each bending portion 20 has multiple rows of second through hole groups 21, each row of the second through hole group 21 includes multiple second through holes 210, the multiple rows of first through hole groups 11 and the multiple rows of second through hole groups 21 are arranged along the arrangement direction of the two bending portions 20 and the support portion 10, and the support member 1 satisfies at least one of the following conditions: the number of rows of the first through hole group 11 is less than the number of rows of the second through hole group 21. The number of the first through holes 110 in the first through hole group 11 is less than the number of the second through holes 210 in the second through hole group 21. The area of the first through holes 110 in the first through hole group 11 is less than the area of the second through holes 210 in the second through hole group 21. The multiple first through holes 110 in each row of the first through hole group 11 correspond to the multiple first through holes 110 in the adjacent row of the first through hole group 11, and at least part of the second through holes 210 in each row of the second through hole group 21 corresponds to the gap 41 between two adjacent second through holes 210 in the adjacent row of the second through hole group 21.
[0044] This embodiment can make different parts have different rigidity and elasticity by opening different through holes on each part. Optionally, the support member 1 can be made of a metal plate etched with a mesh made of carbon fiber. The support part 10, the bending part 20, and the fixing part 30 are all provided with multiple rows of through hole groups, and the multiple rows of through hole groups are arranged along the arrangement direction of the support part 10, the bending part 20, and the fixing part 30. For example, the support part 10 has multiple rows of first through hole groups 11 arranged at intervals, each row of the first through hole group 11 includes multiple first through holes 110 arranged at intervals, each bending part 20 has multiple rows of second through hole groups 21 arranged at intervals, each row of the second through hole group 21 includes multiple second through holes 210 arranged at intervals, and multiple rows of first through hole groups 11 and multiple rows of second through hole groups 21 are arranged along the arrangement direction of the two bending parts 20 and the support part 10. This embodiment can design different first through hole groups 11 and second through hole groups 21 in a variety of ways, so that the rigidity of the bending part 20 is less than the rigidity of the support part 10.
[0045] In the first implementation, the number of rows of the first through hole group 11 can be made smaller than the number of rows of the second through hole group 21, that is, the first through hole group 11 of the supporting portion 10 has fewer rows, and the second through hole group 21 of the bending portion 20 has more rows. The increase in the number of rows can increase the total number of through holes, thereby increasing the elasticity of the bending portion 20 and reducing the stiffness of the bending portion 20, so that the stiffness of the bending portion 20 is less than that of the supporting portion 10.
[0046] In the second implementation, the number of the first through holes 110 in each row of the first through hole group 11 can be made smaller than the number of the second through holes 210 in each row of the second through hole group 21. In other words, the number of the first through holes 110 in the first through hole group 11 is smaller than the number of the second through holes 210 in the second through hole group 21. That is, the number of through holes in each row of the support portion 10 and the bending portion 20 is also different. By increasing the number of the second through holes 210 in the second through hole group 21 in the bending portion 20, the total number of the second through holes 210 in the bending portion 20 can also be increased, thereby increasing the elasticity of the bending portion 20 and reducing the rigidity of the bending portion 20, so that the rigidity of the bending portion 20 is smaller than the rigidity of the support portion 10.
[0047] In the third implementation, the area of the first through hole 110 in the first through hole group 11 can be made smaller than the area of the second through hole 210 in the second through hole group 21. In other words, the areas of the through holes in each through hole group in the support portion 10 and the bending portion 20 are also different. By increasing the area of the second through hole 210 in the second through hole group 21 in the bending portion 20, the overall area of the plurality of second through holes 210 can be increased. That is, the total area of the plurality of first through holes 110 is smaller than the total area of the plurality of second through holes 210, thereby increasing the elasticity of the bending portion 20 and reducing the rigidity of the bending portion 20, so that the rigidity of the bending portion 20 is smaller than the rigidity of the support portion 10. Optionally, the areas of the first through hole 110 and the second through hole 210 can be controlled by controlling the length and width, for example, the length of the second through hole 210 is greater than the length of the first through hole 110, or the width of the second through hole 210 is smaller than the width of the first through hole 110.
[0048] In a fourth implementation, the plurality of first through holes 110 in each row of the first through hole group 11 may correspond to the plurality of first through holes 110 in the adjacent row of the first through hole group 11, and at least a portion of the second through holes 210 in each row of the second through hole group 21 may correspond to the gap 41 between two adjacent second through holes 210 in the adjacent row of the second through hole group 21. In other words, the support portion 10 includes a plurality of rows of first through hole groups 11, each row of the first through hole group 11 includes a plurality of first through holes 110, and each first through hole 110 is disposed adjacent to a first through hole 110 in an adjacent row of the first through hole group 11. The bending portion 20 includes a plurality of rows of second through hole groups 21, each row of the second through hole group 21 includes a plurality of second through holes 210, and each second through hole 210 is disposed adjacent to a second through hole 210 in an adjacent row of the second through hole group 21. In this implementation, the first through holes 110 of a row of first through hole groups 11 can be arranged correspondingly to the first through holes 110 in the adjacent row of first through hole groups 11, and the second through holes 210 of a row of second through hole groups 21 can be arranged correspondingly to the gap 41 between the two second through holes 210 in the adjacent row of second through hole groups 21. By arranging the first through holes 110 and the second through holes 210, even if the second through holes 210 are arranged correspondingly to the gap 41, the elasticity of the bending portion 20 can be increased, and the rigidity of the bending portion 20 can be reduced, so that the rigidity of the bending portion 20 is less than the rigidity of the supporting portion 10.
[0049] It is worth noting that this embodiment can satisfy at least one of the first implementation manner, the second implementation manner, the third implementation manner, and the fourth implementation manner.
[0050] In this embodiment, the area of the second through holes 210 in the second through hole group 21 close to the multiple rows of first through hole groups 11 is smaller than the area of the second through hole 210 in the second through hole group 21 far from the multiple rows of first through hole groups 11 .
[0051] The second through holes 210 in different rows of the second through hole groups 21 in the bending portion 20 are also different. Specifically, the area of the second through holes 210 in the second through hole groups 21 close to the multiple rows of first through hole groups 11 is smaller than the area of the second through holes 210 in the second through hole groups 21 far away from the multiple rows of first through hole groups 11. Optionally, the area of the second through holes 210 in the multiple rows of second through hole groups 21 gradually increases from the direction close to the first through hole group 11 to the direction far away from the first through hole group 11, so that the stiffness and elasticity of the bending portion 20 gradually change, improve the stability of the support member 1, and avoid sudden changes in stiffness and elasticity that make the support member 1 easy to break.
[0052] In this embodiment, the rigidity of the fixing portion 30 is greater than that of the bending portion 20, that is, the fixing portion 30 is a relatively rigid portion relative to the bending portion 20, and the fixing portion 30 is not easy to bend, so that it is better fixed on the supporting member 40 of the folding device 2, thereby improving the stability of the connection between the support member 1 and the folding device 2. Optionally, a plurality of third through holes 300 may be provided on the fixing portion 30, and the rigidity of the fixing portion 30 may be made greater than that of the bending portion 20 by controlling the number, area, arrangement, etc. of the third through holes 300, for example, the design forms of the supporting portion 10 and the bending portion 20 may be referred to, and this embodiment will not be described in detail here.
[0053] Please refer again Figure 8 The folding device 2 provided in this embodiment includes two carriers 40 arranged at an interval, and a support member 1 provided in the above-mentioned embodiment of the present application, wherein one fixing portion 30 of the support member 1 is fixed to one of the carriers 40, and another fixing portion 30 of the support member 1 is fixed to another of the carriers 40, and when the folding device 2 is in the unfolded state, at least a portion of the support portion 10 corresponds to the gap 41 between the two carriers 40.
[0054] In addition to the carrier 40, the folding device 2 may also include a base, a rotating member, a connecting member and other components, and the two carriers 40 are finally folded or unfolded with each other through the cooperation of the above components. The folding device 2 provided in this embodiment adopts the support member 1 provided in the above embodiment of the present application, so that the support part 10 corresponds to the gap 41 between the two carriers 40, thereby transforming the two-plate folding device 2 into a three-plate folding device 2. Without increasing the width of the folding device 2, the creases produced by the flexible screen 50 can be improved.
[0055] Please refer to Fig.10 The shell assembly 3 provided in this embodiment includes a first shell 61, a second shell 62, and a folding device 2 provided in the above embodiment of the present application, and the folding device 2 is connected between the first shell 61 and the second shell 62.
[0056] The housing assembly 3 provided in this embodiment can drive the components of the folding device 2 to move by folding or unfolding the first housing 61 and the second housing 62, and finally fold or unfold the two carriers 40. By adopting the folding device 2 provided in the above embodiment of the present application, the creases generated by the flexible screen 50 can be improved when it is subsequently applied to the electronic device 4.
[0057] Please refer to Figure 11-13 , Fig.11 It is a schematic diagram of the three-dimensional structure of an electronic device in one embodiment of the present application. Fig.12 for Fig.11 An exploded view of the electronic device is shown. Fig.13 This is a schematic diagram of a carrier, a flexible screen, and a support member when the electronic device is in a folded state in one embodiment of the present application. The electronic device 4 of this embodiment includes a flexible screen 50 and a housing assembly 3 as provided in the above embodiment of the present application. The flexible screen 50 is arranged on the same side of the first housing 61, the second housing 62, and the folding device 2. The carrier 40 of the housing assembly 3 is fixed to the flexible screen 50, and at least part of the support member 1 of the housing assembly 3 abuts against the flexible screen 50.
[0058] When the electronic device 4 is in the unfolded state, the support member 1 can abut against the non-display surface of the flexible screen 50. When the electronic device 4 is in the folded state, the fixing portion 30 and the support portion 10 both abut against the non-display surface of the flexible screen 50. The bending portion 20 will be away from the flexible screen 50 during the bending process to prevent scratches. Optionally, the non-display surface of the flexible screen 50 can also be provided with a grid support layer made of stainless steel, carbon fiber, titanium alloy and other materials to support the flexible screen 50, further improving the creases of the flexible screen 50.
