[0042] The present invention provides a rear case 100 .

[0043] Please refer to Figure 1 and Figure 2 In some embodiments of the back cover 100 of the present invention, the back cover 100 includes:

[0044] At least two hard splicing pieces 10, at least two of the hard splicing strips 10 are arranged side by side along the left-right direction of the rear shell 100; and

[0045] At least one elastic splicing piece 20 , each of the elastic splicing strips 20 is disposed between the two rigid splicing strips 10 and is respectively connected to the two rigid splicing strips 10 to cover the gap between the two rigid splicing strips 10 .

[0046] The rear shell 100 proposed in the present application is mainly used in electronic devices 1000 such as display devices. Specifically, when the electronic device 1000 is placed vertically, the up-down direction is the width direction, and the left-right direction is the length direction. The rear shell 100 includes at least two hard splicing strips 10 and at least one elastic splicing strip 20. The hard splicing strips 10 and the elastic splicing strips 20 are both extended along the width direction of the rear shell 100, and the hard splicing strips 10 and the elastic splicing strips 20 are staggered along the length direction of the rear shell 100, that is, each elastic splicing strip is arranged between two hard splicing strips, and each elastic splicing strip 20 is respectively connected to the two hard splicing strips 10 on both sides thereof. Such arrangement enables the back shell 100 to maintain an integral structure, preventing external debris from entering the electronic device 1000 from between two adjacent hard splicing strips; and the flexibility of the back shell 100 is enhanced by a plurality of elastic splicing strips 20, that is, the bending and deformation ability of the back shell 100 in the length direction is increased. It can be understood that when the electronic device 1000 is bent and deformed, the elastic splicing strip 20 is elastically deformed by the pulling of the hard splicing strips 10 on both sides thereof. The elastic deformation of the plurality of elastic splicing strips 20 can prevent the back shell 100 from being damaged due to excessive bending, and can also prevent the bending of the electronic device 1000 from being affected by the insufficient flexibility of the back shell 100. The material of the elastic splicing strip 20 can be but is not limited to elastic fiber material, such as polyurethane fiber, or woven fabric or leather with good elasticity. In addition, the provision of several hard splicing strips 10 in the back shell 100 can improve the flexibility of the back shell 100 while ensuring that the back shell 100 maintains good structural strength. Commonly, the electronic device 1000 is fixedly supported by the back shell 100, for example, the back shell 100 is hung on a wall or a bracket 500 is fixed on the back shell 100 as shown in the figure to support the electronic device 1000. The present application provides several hard splicing strips 10, which can maintain the structural strength of the back shell 100 to support the electronic device 1000, and the use of several hard splicing strips 10 arranged side by side instead of the traditional one-piece back shell 100 can also improve the bending deformation ability of the back shell 100. It can be understood that with such a configuration, when the back shell 100 is bent with the electronic device 1000, the several hard splicing strips 10 will not affect each other, that is, there will be no stress that hinders the movement between two adjacent hard splicing strips 10, thereby improving the flexibility of the back shell 100. The material of the hard splicing strip 10 can be but is not limited to hard plastic, such as ABS plastic (a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S)) or polycarbonate plastic, or metal material, which is not limited here.

[0047] Therefore, it can be understood that in the back shell of the present invention, a plurality of hard splicing strips 10 are arranged side by side, and two adjacent hard splicing strips 10 are connected by an elastic splicing strip 20. The setting of the elastic splicing strip 20 increases the bending deformation ability of the back shell 100. When the electronic device 1000 is bent and deformed in the left and right directions, the two adjacent hard splicing strips 10 move away from each other to stretch the elastic splicing strip 20 between the two hard splicing strips 10, so that the elastic splicing strip 20 produces elastic deformation, avoiding the back shell 100 from being damaged due to excessive bending, and avoiding the back shell 100 from hindering the bending deformation of the electronic device 1000; the setting of the hard splicing strip 10 enables the back shell 100 to maintain a high structural strength while improving the bending deformation ability, ensuring the structural stability of the back shell 100 to support the electronic device 1000. In addition, each elastic splicing strip 20 is connected to the hard splicing strips 10 on both sides thereof to avoid gaps between two adjacent hard splicing strips 10 , thereby preventing foreign matter from entering the electronic device 1000 and improving dustproof capability.

[0048] Please refer to Figure 2 In some embodiments of the back cover 100 of the present invention, the elastic splicing strip 20 is disposed on the surfaces of two adjacent hard splicing strips 10 .

[0049] In this embodiment, any elastic splicing strip 20 is arranged on the surface of two adjacent hard splicing strips 10 to increase the connection area between the elastic splicing strip 20 and the hard splicing strip 10, improve the connection stability between the adjacent elastic splicing strips 20 and the hard splicing strip 10, and further improve the dustproof ability of the rear shell 100. It should be noted that in this embodiment, the elastic splicing strip 20 can be overlapped on the outer surface or the inner surface of the hard splicing strip 10, which is not limited here. The connection method between the elastic splicing strip 20 and the hard splicing strip 10 can be fixed by gluing or by fasteners such as nails and screws, which is not limited here.

[0050] Please refer to Figure 2 and Figure 6 In some embodiments of the back shell 100 of the present invention, the edge of the outer surface of the hard splicing strip 10 forms a limiting step 13, and the limiting step 13 extends along the length direction of the hard splicing strip 10, and the elastic splicing strip 20 overlaps and is fixed to the table top of the limiting step 13.

[0051] In this embodiment, a limiting step 13 is provided on the edge of the outer surface of the hard splicing strip 10, and the limiting step 13 is extended along the length direction of the hard splicing strip 10. At this time, the elastic splicing strip 20 is overlapped and fixed on the table top of the limiting step 13, so that the elastic splicing strip 20 is limited and positioned by the limiting step 13, which is convenient for installing and fixing the elastic splicing strip 20 and also avoids the elastic splicing strip 20 being misplaced due to external force. Moreover, the height of the limiting step 13 can be set to be consistent with the thickness of the elastic splicing strip 20 according to actual needs, so as to maintain the flatness of the outer surface of the rear shell 100 after the elastic splicing strip 20 and the hard splicing strip 10 are assembled, and avoid the elastic splicing strip 20 protruding from the rear shell 100 to increase the risk of damage.

[0052] It is understandable that if the elastic splicing strips 20 are provided on both sides of the hard splicing strips 10, the limiting steps 13 are provided on both side edges of the outer surface of the hard splicing strips 10, and the limiting steps 13 close to each other on the two adjacent hard splicing strips 10 form the effect of limiting grooves to enhance the limiting ability of the elastic splicing strips 20. If the elastic splicing strips 20 are provided on only one side of the hard splicing strips 10, for example, the two hard splicing strips 10 located at the outermost edges of the rear shell 100, the limiting steps 13 can be provided only on the side close to the elastic splicing strips 20, which is not specifically limited here.

[0053] At the same time, the elastic splicing strip 20 is arranged on the outer surface of the hard splicing strip 10, which is convenient for users to disassemble and assemble the elastic splicing strip 20. After the elastic splicing strip 20 is worn out due to long-term use, the elastic splicing strip 20 can be directly replaced without removing the entire rear shell 100 from the electronic device 1000.

[0054] Please refer to Figure 2 In some embodiments of the back shell 100 of the present invention, the two adjacent hard splicing strips 10 are defined as a first hard splicing strip 10 and a second hard splicing strip 10, and a sink 14 is provided on the edge of the outer surface of the first hard splicing strip 10 close to the second hard splicing strip 10, and the sink 14 is extended along the length direction of the first hard splicing strip 10, and a lap portion 15 is protruded from the side of the second hard splicing strip 10 close to the first hard splicing strip 10, and the lap portion 15 is extended along the length direction of the second hard splicing strip 10 and overlapped on the sink 14.

[0055] In this embodiment, two adjacent hard splicing strips 10 are defined as a first hard splicing strip 10 and a second hard splicing strip 10, a sink 14 is provided on the edge of the outer surface of the first hard splicing strip 10 close to the second hard splicing strip 10, and the second hard splicing strip 10 is provided with a lap portion 15 protruding toward the first hard splicing strip 10, and the lap portion 15 is overlapped on the sink 14, so that the first hard splicing strip 10 and the second hard splicing strip 10 are limited and positioned by the sink 14 and the lap portion 15, which is convenient for assembling the first hard splicing strip 10 and the second hard splicing strip 10, and avoids the first hard splicing strip 10 and the second hard splicing strip 10 approaching each other in the length direction of the rear shell 100 to destroy the structural stability of the rear shell 100; further, the sink 14 and the lap portion 15 both extend along the length direction of the hard splicing strip 10, which can block the gap between the two adjacent hard splicing strips 10 and improve the dustproof ability of the rear shell 100.

[0056] It should be noted that, among the three adjacent hard splicing strips 10, the hard splicing strips 10 on both sides may be provided with sinkers 14, and the two side edges of the hard splicing strip 10 in the middle may be protruded with overlapping portions 15, so as to be overlapped with the sinkers 14 on both sides; or the hard splicing strip 10 in the middle may be provided with sinkers 14 on both sides, and the hard splicing strips 10 on both sides may be protruded with overlapping portions 15 toward the hard splicing strip 10 in the middle, so as to be overlapped with the sinkers 14 on both sides; of course, preferably, except for the two hard splicing strips 10 located on the outermost sides of the rear shell 100, the other hard splicing strips 10 may be provided with overlapping portions 15 on one side and sinkers 14 on the other side, so as to maintain the consistency of the structure of the hard splicing strips 10, facilitate replacement and assembly, and facilitate the production of the hard splicing strips 10 without multiple mold openings.

[0057] In some embodiments, the edge of the outer surface of the hard splicing strip 10 is also provided with a limiting step 13 for overlapping the elastic splicing strip 20. At this time, the sink 14 can be opened on the limiting step 13, so as to simultaneously meet the purposes of strengthening the connection strength of the two adjacent hard splicing strips 10, limiting the elastic splicing strip 20, and improving the dustproof ability of the rear shell 100, and making the outer surface of the rear shell 100 a flat surface.

[0058] Please refer to Figure 5 and Figure 6 In some embodiments of the rear housing 100 of the present invention, the hard splicing strip 10 includes:

[0059] A top strip 11, wherein the top strip 11 extends along the length direction of the rigid splicing strip 10, and the elastic splicing strip 20 overlaps and is fixed to the outer surface of the top strip 11; and

[0060] The side panel strip 12 is located on one side of the inner surface of the top panel strip 11 and connected to the top panel strip 11 . The side panel strip 12 is arranged at an angle to the top panel strip 11 . The side panel strip 12 extends along the length direction of the hard splicing strip 10 .

[0061] In this embodiment, the rigid splicing strip 10 includes a top strip 11 and a side strip 12, the side strip 12 is located on one side of the inner surface of the top strip 11, the side strip 12 and the top strip 11 extend in the length direction of the rigid splicing strip 10, and the elastic splicing strip 20 connected to the rigid splicing strip 10 overlaps and is fixed to the outer surface of the top strip 11. It can be understood that the side strip 12 acts as a reinforcing rib, which can prevent the rigid splicing strip 10 from bending and deforming in its length direction, thereby improving the structural stability of the rigid splicing strip 10.

[0062] Furthermore, in some embodiments, the rigid splicing strip 10 includes two side strips 12 , which are arranged opposite to each other and respectively connected to the inner surface of the top strip 11 to further enhance the structural stability of the rigid splicing strip 10 .

[0063] In some embodiments, a matching sink 14 and an overlap 15 are formed between two adjacent rigid splicing strips 10. At this time, the sink 14 can be formed on the outer surface of the top panel strip 11, or the top panel strip 11 can be extended to the outside of the side panel strip 12 to form the overlap 15.

[0064] Please refer to Figure 5 and Figure 8 In some embodiments of the rear shell 100 of the present invention, the rear shell 100 further includes a guide tube 30 , which is extended along the left-right direction of the rear shell 100 and penetrates through the side strips 12 of the hard splicing strips 10 .

[0065] In this embodiment, the rear shell 100 further includes a guide tube 30, which extends along the length direction of the rear shell 100 to penetrate the side strips 12 of the plurality of hard splicing strips 10, and is used to guide the movement of the plurality of hard splicing strips 10 when the rear shell 100 is bent and reset, and to limit the hard splicing strips 10 to prevent the hard splicing strips 10 from moving up and down along the width direction of the electronic device 1000 when the electronic device 1000 is bent and deformed, thereby maintaining the consistency of the curvature change of the rear shell 100 and the display screen 200 during deformation and bending, and the structural stability of the rear shell 100. The guide tube 30 may be made of, but not limited to, stainless steel or hard plastic, etc., which is not limited here.

[0066] Please refer to Figure 1 and Figure 4In some embodiments of the rear shell 100 of the present invention, the rear shell 100 includes a plurality of guide tubes 30 , which are arranged in sequence along the width direction of the rear shell 100 , and each of the guide tubes 30 is passed through the side strips 12 of the plurality of hard splicing strips 10 .

[0067] In this embodiment, the rear shell 100 includes a plurality of guide tubes 30, which are arranged in sequence along the width direction of the rear shell 100 and are all passed through the side strips 12 of the plurality of hard splicing strips 10; such a configuration further improves the limiting and guiding effect of the hard splicing strips 10, so as to maintain the stability of the trajectory of the hard splicing strips 10 during the bending, deformation and resetting process of the rear shell 100, and prevent the hard splicing strips 10 from moving up and down along the width direction of the electronic device 1000.

[0068] In some embodiments, the two ends of the hard splicing strip 10 are fixedly connected to the display screen 200 or the mounting plate 300, while the middle part is in a suspended state. At this time, the number of guide tubes 30 in the middle part can be appropriately increased while the number of guide tubes 30 at the two ends can be reduced to improve the structural stability of the rear shell 100.

[0069] Please refer to Figure 1 and Figure 3 In some embodiments of the rear shell 100 of the present invention, the rear shell 100 further includes a plurality of connecting members 40 , each of the connecting members 40 being used to connect the side strips 12 of two adjacent hard splicing strips 10 .

[0070] In this embodiment, a connector 40 is provided in the rear shell 100 for connecting the side strips 12 on two adjacent rigid splicing strips 10. Such a configuration allows the two adjacent rigid splicing strips 10 to be connected to each other, thereby improving the structural stability of the rear shell 100, so as to improve the positional stability of the rigid splicing strips 10 when the rear shell 100 is bent and deformed. In this embodiment, the connector 40 may be, but is not limited to, a bolt, a clamp, a spring (the two ends of the spring are respectively connected to the two side plates) or a magnetic structure, etc., which are not limited here. In addition, a plurality of connectors 40 may be provided between two adjacent rigid splicing strips 10, and the plurality of connectors 40 may be spaced apart along the length direction of the rigid splicing strip 10 to improve the connection strength between the two adjacent rigid splicing strips 10.

[0071] It should be noted that, in this embodiment, if a hard splicing strip 10 is provided on both sides of the hard splicing strip 10, the hard splicing strip 10 may be provided with one side strip 12 on both sides of the top strip 11, and each side strip 12 is connected to the side strip 12 on the hard splicing strip 10 on the corresponding side through a connecting piece 40. Of course, it is also possible to provide only one side strip 12 on the hard splicing strip 10 located in the middle, and the side strip 12 is connected to the side strips 12 on the hard splicing strips 10 on both sides through connecting pieces 40. As for the two hard splicing strips 10 located on the outermost sides of the rear shell 100, they are only adjacent to one hard splicing strip 10, that is, the hard splicing strip 10 located on the outermost sides is only provided with one side strip 12 connected to the side strip 12 on the adjacent hard splicing strip 10.

[0072] Please refer to Figure 3 In some embodiments of the rear shell 100 of the present invention, the connecting member 40 is a clamping member, and the clamping member clamps the side strips 12 of two adjacent hard splicing strips 10.

[0073] In this embodiment, the connecting member 40 is a clamping member, mostly an elastic clamping member, which clamps the side strips 12 on the two rigid splicing strips 10 to connect the two adjacent rigid splicing strips 10. The structure is simple and easy to disassemble and assemble.

[0074] For further information, please refer to Figure 3 and Figure 7 In some embodiments of the rear housing 100 of the present invention, the side panel strip 12 is provided with a clamping hole 18 , and the clamping end of the clamping member is provided with a clamping hook 41 , and the clamping hook 41 is hooked in the clamping hole 18 .

[0075] The technical solution of the aforementioned embodiment is to clamp the side strips 12 on two adjacent hard splicing strips 10 by a clamping member; commonly, the clamping member has two clamping parts, and the two clamping parts are arranged opposite to each other to form a clamping space, and the side strips 12 on two adjacent hard splicing strips 10 are clamped in the clamping space, and the surface of each side strip 12 facing away from the other side strip 12 abuts against one of the clamping parts; in this embodiment, a clamping hole 18 is opened on the side strip 12, and a clamping hook 41 is provided at the clamping end of the clamping part. When the clamping part clamps the two side strips 12, the hook 41 is hooked in the clamping hole 18 to prevent the clamping member from falling off the hard splicing strip 10, thereby improving the connection stability between the clamping member and the hard splicing strip 10, thereby improving the structural stability of the rear shell 100.

[0076] It should be noted that in this embodiment, the clamping member includes two clamping parts, and the clamping hook 41 can be provided at the clamping end of only one of the clamping parts, and the clamping hole 18 can be provided on the corresponding side strip 12; or the clamping hook 41 can be provided at the clamping ends of both clamping parts, and the clamping hole 18 can be provided on both side strips 12, which is not limited here. Preferably, the clamping hooks 41 are provided at both clamping ends of the clamping member, which can not only improve the connection stability between the clamping member and the hard splicing strip 10, but also make the hard splicing strip 10 maintain consistency and facilitate processing.

[0077] Please refer to Figure 5 and Figure 6 In some embodiments of the back shell 100 of the present invention, between two adjacent hard splicing strips 10, a limiting column 16 is protruded from the surface of the side panel strip 12 of one of the hard splicing strips 10 facing the other hard splicing strip 10, and a limiting hole 17 is provided on the side panel strip 12 of the other hard splicing strip 10, and the limiting column 16 is inserted into the limiting hole 17.

[0078] In this embodiment, two adjacent rigid splicing strips 10 are defined as a first rigid splicing strip 10 and a second rigid splicing strip 10, wherein a limiting column 16 is convexly provided on the surface of the side strip 12 of the first rigid splicing strip 10 facing the second rigid splicing strip 10, and a limiting hole 17 is provided on the side strip 12 of the second rigid splicing strip 10, and the limiting column 16 is inserted into the limiting hole 17, so as to limit the position of the two adjacent rigid splicing strips 10 during assembly, and has a positioning function, which is convenient for assembly. Among them, between two adjacent rigid splicing strips 10, the limiting column 16 and the limiting hole 17 can be set in multiple groups, which is not limited here.

[0079] Please refer to Figures 8 to 11 The present invention further proposes an electronic device 1000, comprising a display screen 200 and a rear shell 100 as described in any of the aforementioned embodiments, wherein the rear shell 100 is disposed on the back side of the display screen 200. The specific structure of the rear shell 100 is referred to any of the aforementioned embodiments, and will not be described in detail here. Since the electronic device 1000 proposed by the present invention applies all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought by the aforementioned technical solutions, which will not be described in detail here.

[0080] Please refer to Fig.11 and Fig.12 In some embodiments of the electronic device 1000 of the present invention, the electronic device 1000 further includes a mounting plate 300, wherein the mounting plate 300 is disposed between the display screen 200 and the rear shell 100 and can be bent, and the mounting plate 300 is detachably connected to the rear shell 100.

[0081] In this embodiment, the electronic device 1000 further includes a mounting plate 300, which can be bent and arranged, and can be a metal plate with a certain elasticity such as an aluminum plate, or a material such as a plastic plate. The mounting plate 300 is arranged between the display screen 200 and the rear shell 100, and can be a side plate surface of the mounting plate 300 so that the display screen 200 is mounted on the mounting plate 300, so that the mounting plate 300 is bent and deformed together when the electronic device 1000 is bent and deformed. The arrangement of the mounting plate 300 can improve the structural strength of the electronic device 1000. It can be understood that the display screen 200, the mounting plate 300 and the rear shell 100 are arranged in sequence along the front-to-back direction. When the electronic device 1000 is bent, the stretching degree of the mounting plate 300 when bending is less than the stretching degree of the rear shell 100. Therefore, even if the mounting plate 300 is a complete plate surface, when it has a certain elasticity, it will not affect the large-angle bending deformation of the rear shell 100, thereby improving the structural strength of the electronic device 1000 while avoiding affecting the large-angle bending demand of the electronic device 1000. Furthermore, the mounting plate 300 is detachably connected to the rear housing 100 , and the mounting plate 300 can be used to limit the installation of the various splicing strips on the rear housing 100 to avoid directly installing and fixing multiple splicing strips on the display screen 200 and increasing the risk of damaging the display screen 200 .

[0082] It should be noted that, in the present embodiment, the detachable connection method between the mounting plate 300 and the rear shell 100 may be a snap connection, a bolt connection, an adhesive connection or a combination of at least two detachable connection methods; it may be a direct detachable connection, or it may be such that both the mounting plate 300 and the rear shell 100 are connected to an intermediate element, and at least one of the mounting plate 300 and the rear shell 100 is detachably connected to the intermediate element; all the hard splicing strips 10 on the rear shell 100 may be respectively connected to the mounting plate 300, or only some of the hard splicing strips 10 may be connected to the mounting plate 300, and there is no limitation on this.

[0083] Please refer to Figure 12 to Figure 14 In some embodiments of the electronic device 1000 of the present invention, the mounting plate 300 is provided with a snap-fitting portion 310 , and the inner surface of the hard splicing strip 10 is provided with a snap-fitting portion 19 , and the snap-fitting portion 310 is snap-fitted with the snap-fitting portion 310 .

[0084] In this embodiment, a buckle 19 is provided on the hard splicing strip 10, and a snap-on portion 310 is provided on the mounting plate. When the rear shell 100 is assembled on the mounting plate, the buckle 19 and the snap-on portion 310 are snap-fitted to connect the hard splicing strip 10 to the mounting plate. In some embodiments, the buckle 19 is convexly provided on the inner surface of the hard splicing strip 10, and a barb is formed at the free end. The snap-on portion 310 is provided on the surface of the mounting plate facing the rear shell 100, and a snap interface is provided. The buckle 19 is inserted into the snap interface and the barb is hooked at the edge of the snap interface, thereby preventing the hard splicing strip 10 from being separated from the mounting plate, improving the connection strength between the rear shell and the mounting plate and the structural stability of the electronic device.

[0085] In some embodiments, the clip 19 is provided at the end of the hard splicing strip 10, and the clip 19 is provided at both ends of the hard splicing strip 10, and the clip parts 310 are correspondingly provided on the upper and lower sides of the mounting plate 300, so that both ends of the hard splicing strip 10 are fixed on the mounting plate 300, thereby improving the connection strength between the hard splicing strip 10 and the mounting plate, and maintaining the consistency of the curvature change of the rear shell 100 during deformation and bending with the mounting plate 300.

[0086] In some embodiments, the rigid splicing strip 10 and the mounting plate 300 are further connected by screws, etc., to further improve the connection strength between the rear housing 100 and the mounting plate 300, and improve the structural stability of the electronic device 1000. The screws can be directly inserted into the rigid splicing strip 10 and the mounting plate 300, or as in the following embodiment, a fixing member 400 can be provided between the mounting plate 300 and the rigid splicing strip 10, and the fixing member 400 is respectively connected to the rigid splicing strip 10 and the display screen 200 by screws, which is not limited here.

[0088] In this embodiment, the electronic device 1000 also includes a fixing member 400, which has two fixing parts that are arranged at an angle and connected to each other, one of which is fixedly connected to the mounting plate 300, and the other is fixedly connected to the hard splicing strip 10, so that the hard splicing strip 10 and the mounting plate 300 are detachably connected; the connection method between the mounting plate 300 and the fixing part and between the hard splicing strip 10 and the fixing part can be but is not limited to bolt connection, clamping or other connection methods, which are not limited here.

[0089] It should be noted that the connection methods of different rigid splicing strips 10 on the rear shell 100 and the mounting plate 300 may be different. Some rigid splicing strips 10 may be connected to the mounting plate 300 by the snap-fit ​​structure of the snap-fit ​​part 19 and the snap-fit ​​part 310 or by direct screw locking as in the above embodiment, and the other part of the rigid splicing strips 10 may be connected to the mounting plate 300 by the above-mentioned fixing member 400. For example, the two rigid splicing strips 10 on the outermost side of the rear shell 100 may be connected to the mounting plate 300 by the above-mentioned fixing member 400, and the rigid splicing strip 10 in the middle may be connected to the mounting plate 300 by the snap-fit ​​structure of the snap-fit ​​part 310. It should also be noted that each rigid splicing strip 10 may be connected to the mounting plate 300 by a combination of multiple fixing methods, such as using a snap-fit ​​structure and a screw locking structure at the same time, so as to improve the connection stability between the rigid splicing strip 10 and the mounting plate 300. The specific connection method between the rigid splicing strip 10 and the mounting plate 300 is not limited here.
