Therefore, the housing of this type of energy storage device must have a partition inside.

[0003] However, the above structure has the following shortcomings: its partition plate is usually integrally formed with the energy storage device housing, so the circuit board can only be assembled to the partition plate for easy installation; and when the circuit board fails, the entire energy storage device housing has to be removed before the circuit board can be replaced. If the energy storage device is welded to the applied equipment, it will obviously be difficult to replace the circuit board. Summary of the Invention

[0008] Furthermore, the inner side wall of the top frame extends inward to form a holding portion, and the inner side wall of the bottom frame extends inward to form a supporting portion. The first mounting groove is formed between the inner side wall of the top frame and the holding portion, and the second mounting groove is formed between the inner side wall of the bottom frame and the supporting portion.

[0009] Furthermore, the inner walls on both sides of the pressing portion and the inner walls on both sides of the lifting portion are respectively provided with reinforcement structures, and the reinforcement structures are integrally formed with the pressing portion / lifting portion.

DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0021] like Figures 1 to 5 As shown, the utility model provides a double-layer energy storage device housing, including a top frame 1 and a bottom frame 2. A first connecting portion 11 is provided on one side of the top frame 1, and a second connecting portion 21 is provided on one side of the bottom frame 2. A first connecting hole 12 is provided on the top of the first connecting portion 11, and a second connecting hole 22 is provided on the top of the second connecting portion 21. The first connecting hole 12 and the second connecting hole 22 are connected and fixed by a latch.

[0022] The bottom of the top frame 1 is provided with a first mounting groove 13 , the top of the bottom frame 2 is provided with a second mounting groove 23 , a partition 3 is detachably provided between the first mounting groove 13 and the second mounting groove 23 , and the partition 3 is provided with a wire hole 31 .

[0023] The present invention can be applied in the following manner: first, the bottom frame 2 is welded to the application equipment (such as a car), and then the circuit board is assembled into the bottom frame 2 and fixed, and then the partition 3 is assembled to the first mounting groove 13 so that a part of the partition 3 is located outside the first mounting groove 13, and the wires of the circuit board are led to the top of the partition 3 through the wire hole 31; then the energy storage module is installed on the partition 3 and connected with the wires of the circuit board, and then the pin is inserted into the second connecting hole 22 with the top exposed outside the second connecting hole 22, and then the first connecting hole 12 is put on the pin, and the top frame 1 and the bottom frame 2 are installed in alignment, and finally a top cover is added or fixed on the top of the top frame 1 to complete the assembly.

[0024] When the energy storage module fails, the top frame 1 and the bottom frame 2 can be directly removed for repair and replacement; when the circuit board fails, the top frame 1 and the partition 3 can be removed for maintenance and replacement, thereby improving convenience.

[0025] Of course, in order to improve the stability of the installation, the top frame 1 and the bottom frame 2 can be equipped with corresponding multiple holes respectively to achieve positioning installation between the application equipment, so that the top frame 1 and the bottom frame 2 do not need to be fixed by welding or screw connection, and can be relatively fixedly assembled.

[0026] In this embodiment, the inner side wall of the top frame 1 extends inward to form a holding portion 14, and the inner side wall of the bottom frame 2 extends inward to form a supporting portion 24. The first mounting groove 13 is formed between the inner side wall of the top frame 1 and the holding portion 14, and the second mounting groove 23 is formed between the inner side wall of the bottom frame 2 and the supporting portion 24.

[0027] That is, the partition 3 is placed in the first installation groove 13 to achieve positioning and assembly, and then the holding portion 14 is pressed on the partition 3 to achieve secondary fixation of the partition 3, so that the partition 3 can be fixed and assembled without the need for fixing by means of screws or the like.

[0028] In this embodiment, the inner walls on both sides of the pressing portion 14 and the inner walls on both sides of the lifting portion 24 are respectively provided with reinforcement structures 4 , and the reinforcement structures 4 are integrally formed with the pressing portion 14 / lifting portion 24 .

[0029] In actual use, the reinforcement structure 4 includes two reinforcement parts 41. The two reinforcement parts 41 are arranged in parallel and at intervals. The two reinforcement parts 41 cooperate to guide the assembly of external energy storage devices / components.

[0030] That is, in addition to improving the strength of the top frame 1 and the bottom frame 2, the two reinforcing parts 41 can also be used to form guide rails, that is, the circuit board / energy storage module can be provided with a guide groove, and then the circuit board / energy storage module can be "slid into" the bottom frame 2 / top frame 1 by sliding the guide groove on the reinforcing part 41, thereby achieving the effect of positioning and installing the circuit board in the bottom frame 2 and positioning and installing the energy storage module in the top frame 1.

[0031] In this embodiment, the partition 3 is provided with at least four screw holes 32 , and the four screw holes 32 are distributed on the partition 3 in a rectangular array; the four screw holes 32 cooperate with each other to be externally connected to the same handle.

[0032] That is, when the partition 3 needs to be removed, the partition 3 can be screwed or threaded to the external handle, and then the partition 3 can be taken up by lifting the handle; and when the partition 3 does not need to be taken up, the handle can be removed to avoid affecting the installation of the energy storage module.

[0033] In this embodiment, the bottom of the base frame 2 is provided with a welding bevel 25, and positioning pins 26 are arranged at intervals on the welding bevel 25. The positioning pins 26 are used to insert into the holes of the application equipment for initial positioning. Subsequently, the base frame 2 and the application equipment can be fixed by welding at the welding bevel 25. The welding bevel 25 is mainly used to facilitate the fixing of the solder material, thereby ensuring the stability of the welding.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
