DETAILED DESCRIPTION

[0043] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0044] Figure 1 This is a schematic diagram of the structure of a battery provided by an exemplary embodiment of the present application. Figure 1 As shown, the battery 300 provided in the embodiment of the present application may include a battery cell 310 and a battery box 100 . The battery cell 310 may be disposed in the battery box 100 , and the battery box 100 protects the battery cell 310 .

[0045] Figure 2 This is a schematic diagram of the structure of a battery box provided by an exemplary embodiment of the present application after the side frame is removed. Figure 1 and Figure 2 As shown, the battery box 100 provided in the embodiment of the present application may include a bottom plate 110 and a side frame 120. The side frame 120 and the bottom plate 110 may be combined to form a receiving cavity 130. The battery cell 310 may be received in the receiving cavity 130. The bottom plate 110 and the side frame 120 may be detachably connected.

[0046] It should be noted that, when the side frame 120 is assembled on the base plate 110, the side frame 120 can protect the internal battery cells 310 and prevent external foreign objects from colliding with the battery cells 310; when it is necessary to repair the components in the accommodating cavity 130, the side frame 120 and the base plate 110 can be detached from each other, and the battery cells 310 are exposed on all sides of the accommodating cavity 130. In this way, the staff can repair the components in different orientations, which effectively expands the staff's operating space and improves the maintenance efficiency.

[0047] Figure 3 This is a schematic diagram of the structure of a side panel provided by an exemplary embodiment of the present application. Figure 2 and Figure 3 As shown, the bottom plate 110 is provided with a plurality of slide grooves 111, and the plurality of slide grooves 111 are distributed along the circumference of the bottom plate 110. The side frame 120 may include a plurality of side plates 121, which are connected end to end and slidably matched with the corresponding slide grooves 111.

[0048] Specifically, in actual application, when the side panel 121 needs to be assembled on the bottom plate 110, the side panel 121 can be slid into from one end of the slide groove 111, and the side panel 121 and the slide groove 111 slide together to complete the assembly operation; when the side panel 121 needs to be removed from the bottom plate 110, the side panel 121 can also be slid out from one end of the slide groove 111, and the side panel 121 is separated from the bottom plate 110 to complete the disassembly operation.

[0049] It should be understood that the side panel 121 slides in cooperation with the slide groove 111, and the side panel 121 can be assembled on or detached from the bottom plate 110 through a simple sliding process. The assembly and disassembly process is simple and quick, which can effectively improve the assembly and disassembly efficiency.

[0050] In one embodiment, the bottom plate 110 is a rectangular plate, and the four sides of the rectangular plate are respectively provided with sliding grooves 111 . There are four side plates 121 , and the four side plates 121 are matched with the four sliding grooves 111 in a one-to-one correspondence.

[0051] Figure 4 A schematic structural diagram of a base plate provided for an exemplary embodiment of the present application. Figure 5 for Figure 4 A magnified schematic diagram of center A. Figure 6 This is a schematic diagram of the structure of a side panel provided by another exemplary embodiment of the present application. Figures 4 to 6 As shown, the cross section of the slide groove 111 forms a “convex” shaped cross section, and a slider 122 is provided at the bottom of the side plate 121 . Correspondingly, the slider 122 is a “convex” shaped structure that cooperates with the slide groove 111 .

[0052] In practical applications, the slide groove 111 with a "convex" shaped cross-section cooperates with the slider 122 with a "convex" shaped structure. On the one hand, the top wall of the slide groove 111 is used to limit the slider 122 from detaching from the slide groove 111 from the top of the slide groove 111, thereby improving the overall stability and safety of the assembly structure. On the other hand, during assembly or disassembly, the slide groove 111 with a "convex" shaped cross-section has better guidance for the slider 122, thereby improving the stability and accuracy of the slider 122 during the sliding process and preventing the slider 122 from deviating from the predetermined path.

[0053] Figure 7 A schematic structural diagram of multiple side panels and connecting hinges provided as an exemplary embodiment of the present application. Figure 8 This is a schematic diagram of the structure of a connecting hinge provided by an exemplary embodiment of the present application. Figure 7 and Figure 8 As shown, the battery box 100 may also include a connecting hinge 140, a first fastener (not shown in the figure) and a second fastener (not shown in the figure), the connecting hinge 140 includes a first connecting piece 141 and a second connecting piece 142, and in two adjacent side panels 121, the first fastener can detachably connect the first connecting piece 141 and one of the side panels 121, and the second fastener can detachably connect the second connecting piece 142 and the other side panel 121.

In this way, while ensuring that the multiple side panels 121 can be detached from each other, the overall strength and stability of the side frame 120 can be improved.

[0055] In one embodiment, the first fastener and the second fastener may be bolts, screws, pins, etc.

[0056] Fig. 9 This is a schematic diagram of the structure of two adjacent side panels provided by an exemplary embodiment of the present application.

Correspondingly, the battery box 100 may further include a third fastener (not shown in the figure), and the third fastener is detachably matched with the first connection hole 123 and the second connection hole 124.

[0057] It should be understood that, in actual applications, by providing a third fastener between two adjacent side panels 121, the functions of relative fixation and relative detachability of the two adjacent side panels 121 can be achieved. In this way, while ensuring that the multiple side panels 121 can be detached from each other, the overall strength and stability of the side frame 120 can be improved.

[0060] Fig.10 A schematic structural diagram of a side frame provided by an exemplary embodiment of the present application. Fig.11 This is a schematic diagram of the structure of a base plate provided by an exemplary embodiment of the present application. Fig.10 and Fig.11 As shown, a connecting wall 125 is protruded from one side of the side frame 120 close to the accommodating cavity 130, and the connecting wall 125 is provided with a third connecting hole 126. The bottom plate 110 is provided with a fourth connecting hole 112.

[0061] It should be understood that, in actual applications, by providing the connecting wall 125 and the fourth fastener, the functions of the side frame 120 being relatively fixed to the base plate 110 as a whole and being relatively detachable can be achieved. In this way, the side frame 120 can be detached from the base plate 110 as a whole without disassembling the side frame 120 into a plurality of side plates 121, thereby effectively improving the disassembly efficiency.

[0062] In one embodiment, the fourth fastener may be a bolt, a screw, a pin, etc.

[0063] In one embodiment, the number of third connecting holes 126 is multiple (two or more), the number of fourth connecting holes 112 is the same as the number of third connecting holes 126 and corresponds one to one, and each group of third connecting holes 126 and fourth connecting holes 112 can be used to assemble the fourth fastener.

[0064] It should be noted that in Fig.10In the embodiment, the side frames 120 include a plurality of side plates 121 which can be connected to each other by the aforementioned connecting hinges 140 or the third fasteners, or can be connected to each other by end-to-end welding.
