[0068] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0069] Combination Figures 1 to 11 The battery cover provided in the embodiment of the present application includes: a frame 100, which is a bending structure to form a bending groove 110; a flexible shell 200, including a first part 210 and a second part 220 connected to each other, the first part 210 is bent and fixed to the outer periphery of the frame 100, and the second part 220 can rotate relative to the first part 210, that is, the first part 210 is a bending section, and the second part 220 is a straight section.

[0070] The battery cover also includes a cover plate 300, which is fixed to the second portion 220 of the flexible shell 200 and is rotatably connected to the frame 100 through the second portion 220. The frame 100 is used to be connected to the frame 410 of the tablet computer along the side of the tablet computer through the bending groove 110, so that the second portion 220 of the flexible shell 200 drives the cover plate 300 to rotate relative to the frame 100 to cover the back of the frame 410 of the tablet computer.

[0071] Exemplarily, the first portion 210 is bonded to the frame 100 , the second portion 220 is bonded to the cover plate 300 , and the flexible shell 200 is made of a leather flexible material.

[0072] With such a design, the battery cover is connected to the frame 100 having the bending groove 110 and the cover plate 300 through the flexible shell 200, and can be installed from the side of the tablet computer using the bending groove 110. The structure is stable and the installation is convenient. At the same time, the appearance structure of the tablet computer installed with the battery cover can be similar to that of a book, which can provide a better visual experience for users who like reading, and indirectly increase the added value of the product.

[0073] Furthermore, a glue layer is provided on the back edge of the frame body 410 , and the cover plate 300 of the battery cover can be bonded to the frame body 410 through the glue layer using a pressure-maintaining device, thereby completing the assembly of the battery cover.

[0074] In some embodiments, a connecting hole is provided on the groove wall of the bending groove 110 of the skeleton 100, and a mounting hole is provided on the frame 410. The skeleton 100 is fixed to the frame 410 via a connector 500 penetrating the connecting hole and the mounting hole.

[0075] refer to Figure 1 , Figure 8 , Fig. 9 and Fig.10In some embodiments, a convex rib 111 is provided on the groove wall of the bending groove 110 , and the connecting hole includes a first screw hole 112 , the first screw hole 112 is provided on the convex rib 111 , and the first screw hole 112 is consistent with the notch direction of the bending groove 110 .

[0076] The frame 410 is provided with a socket 420, the mounting hole includes a first mounting sub-hole 430, the inner wall of the socket 420 is provided with a first mounting sub-hole 430, the connecting member 500 includes a first threaded member, and the convex rib 111 is configured to be plugged into the socket 420 so that the first threaded member passing through the first mounting sub-hole 430 and the first screw hole 112 fixes the socket 420 and the convex rib 111.

[0077] Compared with the method of connecting the skeleton 100 and the frame body 410 by glue dispensing or snapping, the threaded connection structure is more stable and convenient to disassemble.

[0078] Continue to combine Figure 8 In some embodiments, there are at least two convex ribs 111 , and the two convex ribs 111 are spaced apart from each other on the groove wall of the bending groove 110 . There are at least two sockets 420 on the frame 410 , and they are arranged one by one corresponding to the convex ribs 111 .

[0079] In this way, the connection stability between the skeleton 100 and the frame 410 is further improved. In more examples, the number of the convex ribs 111 can also be three.

[0080] like Fig. 9 As shown, in some embodiments, an extension plate 120 is provided on the groove wall of the bending groove 110, and the extension plate 120 extends toward the outside of the skeleton 100 along the width direction of the skeleton 100, and the connecting hole includes a second screw hole 121, and the second screw hole 121 is arranged on the extension plate 120; the mounting hole includes a second mounting sub-hole 440, and the frame body 410 is provided with a second mounting sub-hole 440, and the connecting member 500 includes a second threaded member, and the extension plate 120 is fixed to the skeleton 100 by passing through the second screw hole 121 and the second mounting sub-hole 440.

[0081] In some embodiments, there are at least two extension plates 120 , and the two extension plates 120 are disposed at intervals on the groove wall of the bending groove 110 .

[0082] In some other examples, there are three extension plates 120 , and the three extension plates 120 are disposed at intervals on the groove wall of the bending groove 110 .

[0083] In this way, by setting the convex rib 111 and the extension plate 120 with openings on the frame 100 and threading them with the corresponding mounting holes of the frame 410 of the tablet body 400, the frame 100 can be fixed in both the width and thickness directions, thereby comprehensively strengthening the connection stability of the battery cover on the tablet body 400.

[0084] Combination Figure 7 In more examples, a limiting rib is provided on the outer wall surface of the bending groove of the skeleton 100 away from the cover plate, which is configured to be bonded to the end of the first part of the flexible shell 200, and the protruding height of the limiting rib is consistent with the thickness of the first part of the flexible shell 200.

[0085] In this way, not only the contact area between the flexible shell 200 and the frame 100 is increased to enhance the connection strength, but also the flatness between the flexible shell 200 and the frame 100 is ensured.

[0086] In some embodiments, the first portion 210 of the flexible housing 200 is rotatably connected to the second portion 220 via a connection portion 230 , and a groove 231 is provided on the connection portion 230 so that the second portion 220 can rotate relative to the first portion 210 within an angle range of 0-180 degrees.

[0087] After the battery cover is installed on the frame 410, the cover plate 300 is rotated relative to the frame 100 through the groove 231 of the connecting portion 230 on the flexible shell 200 until the angle between the two is greater than 90 degrees, thereby exposing the second screw hole 121 on the frame 100, so that the frame 100 and the frame 410 can be connected by the second screw hole 121 and the second mounting sub-hole 440 using a second screw member.

[0088] Further, combined with Figures 1 to 3 The assembly process of the battery cover of the embodiment of the present application is as follows: the frame 100, the cover plate 300 and the flexible shell 200 are combined into one by dispensing glue, and then the cover plate 300 is flipped to a state where the angle with the frame 100 is greater than 90 degrees, exposing the connection hole of the frame 100, so that after the frame 100 is installed into the frame 410 of the tablet computer through the bending groove 110, the threads between the frame 100 and the frame 410 are fixed.

[0089] After the skeleton 100 and the frame 410 are screwed, the cover 300 is rotated to a position parallel to the back of the frame 410 so as to be bonded to the preset adhesive layer on the frame 410. The battery cover is assembled on the tablet computer by maintaining pressure with a pressure-maintaining jig to achieve a perfect fit.

[0090] In order to ensure the flatness of the flexible shell 200, which serves as the spine structure of the book-shaped tablet computer, and the front and back surfaces of the frame 410, limiting end covers 600 are provided at both ends of one side of the frame 410 so that the step difference of the battery cover after being assembled to the frame 410 remains consistent, thereby ensuring the appearance of the tablet computer.

[0091] In the second aspect, an embodiment of the present application provides a tablet computer, which includes a tablet body 400 and a battery cover provided by any embodiment of the first aspect, the tablet body 400 includes a frame 410, the frame 100 of the battery cover is connected to the side of the frame 410, and the cover plate 300 is covered on the back of the frame 410.

[0092] It should be noted that the assembly process of the tablet computer of this embodiment is as follows: first, the circuit board and other components of the tablet computer are installed on the frame 410, and then the battery cover is installed from the side. The cover plate 300 can be flipped over through the flexible shell 200 on the battery cover, and the frame 100 of the battery cover is fixed to the frame 410 by screws. Finally, the cover plate 300 is lowered and pasted on the middle frame.

[0093] In some embodiments, in combination Fig.10 and Fig.11 The tablet computer also includes at least two limiting end covers 600 , which are respectively connected to opposite ends of one side of the frame 410 . Along the thickness direction of the frame 410 , the limiting end covers 600 protrude relative to the frame 410 and abut against the frame 100 .

[0094] In some embodiments, limiting protrusions 450 are provided on opposite ends of one side of the frame body 410 , and limiting grooves are provided on the limiting end cover 600 , and the limiting protrusions 450 are snap-fitted into the limiting grooves.

[0095] In this way, the setting of the limiting end cover 600 can not only ensure the flatness of the battery cover after being assembled on the frame body 410, but also limit the battery cover along the width direction of the frame body 410, thereby improving the installation stability of the battery cover.
