Similarly, the second fastening part 8 on the box cover 2 can be fastened to the fastened part 7, allowing the box cover 2 to be initially positioned on the mounting bracket 3. The box cover 2 and the box body 1 are then locked in place using the connector 5, making installation convenient, simple, and easy to maintain.

[0029] Specifically, refer to Figure 5The mounting bracket 3 includes a first mounting plate 31 and a second mounting plate 32 that are perpendicularly connected to each other. The first mounting plate 31 and the second mounting plate 32 are integrally connected. The first mounting plate 31 is used to fix the bracket to the battery cabinet. A mounting hole 321 is formed on the second mounting plate 32 and is formed along the length of the second mounting plate 32. The box body 1 has a first abutment plate 16 extending outward on the left and right sides of the opening, and a first fastening part 6 is provided on the first abutment plate 16. When the first fastening part 6 is fastened to the mounting hole 321, the first abutment plate 16 can fit against the second mounting plate 32. In this embodiment, the mounting bracket 3 also includes a third mounting plate 33, which is perpendicularly connected to the second mounting plate 32 and parallel to the first mounting plate 31. The cross-section of the mounting bracket 3 is a "ㄣ" structure, and the third mounting plate 33 can abut against the outer wall of the box body 1. By setting the third mounting plate 33, the contact area between the mounting bracket 3 and the box 1 can be increased, thereby improving the installation stability of the mounting bracket 3 on the box 1.

[0030] Specifically, refer to Figure 4 and Figure 6 The first fastening part 6 is integrally connected to the first abutment plate 16 to improve the connection strength between the first fastening part 6 and the first abutment plate 16. The first fastening part 6 includes a connecting block 61 and a fastening block 62. The connecting block 61 is vertically connected to the first abutment plate 16 and extends towards the box body 1 away from the opening. The fastening block 62 is integrally connected to the connecting block 61 and extends downward. When the first fastening part 6 is fastened to the mounting hole 321, the lower edge of the connecting block 61 can abut against the lower edge of the mounting hole 321, and the fastening block 62 fastens to the side of the second mounting plate 32 away from the first abutment plate 16. During installation, the first fastening parts 6 on both sides of the box body 1 are inserted into the mounting holes 321 respectively, the first abutment plate 16 and the second mounting plate 32 abut against each other and fit together, and the box body 1 is lowered to complete the initial positioning of the box body 1. In other embodiments, the first fastening part 6 can also be an L-shaped rod structure, and the number of the first fastening parts 6 can also be set according to the actual situation.

[0031] In this embodiment, in conjunction with the first fastening part 6, each mounting bracket 3 only needs one locking screw 4 to lock and fix the box body 1 and the mounting bracket 3, making the locking or unlocking process relatively convenient. The first abutment plate 16 has a screw hole 161, and the second mounting plate 32 has a locking hole. The locking screw 4 passes through the screw hole 161 of the first abutment plate 16 and is then locked in the locking hole of the second mounting plate 32. In other embodiments, each mounting bracket 3 can be provided with two or more locking screws 4, but this would make the installation more cumbersome and would not significantly improve the installation stability of the box body 1.

[0032] Furthermore, the screw hole 161 on the first abutment plate 16 extends along the direction perpendicular to the length of the first abutment plate 16. The screw hole 161 has a strip-shaped hole structure, which ensures that the screw hole 161 can be aligned with the locking hole, facilitating the subsequent locking operation of the locking screw 4.

[0033] Furthermore, refer to Figure 5 and Figure 6 Along the length of the second mounting plate 32, a horizontal positioning section 3212 and an inclined guide section 3211 are provided at the lower edge of the mounting hole 321. The lower end of the inclined guide section 3211 is connected to the horizontal positioning section 3212, and the first fastening part 6 can rest on the horizontal positioning section 3212 along the inclined guide section 3211. In this embodiment, two inclined guide sections 3211 are provided and symmetrically distributed at both ends of the horizontal positioning section 3212, making the lower edge of the mounting hole 321 resemble a V-shaped structure. The length of the horizontal positioning section 3212 is greater than the thickness of the connecting block 61, so that the connecting block 61 can rest on the horizontal positioning section 3212 and can adapt to dimensional deviations. The inclined guide section 3211 allows for more accurate initial positioning of the box 1, making the screw holes 161 on the first abutment plate 16 more accurately aligned, facilitating the subsequent locking operation of the locking screw 4 on the box 1. In other embodiments, only one tilting guide segment 3211 and one horizontal positioning segment 3212 may be provided.

[0034] Specifically, the box body 1 has a second abutment plate 17 extending upward from the lower edge of the opening. The two ends of the second abutment plate 17 along its length each have a first notch 171 to form a fastening portion 7. The left and right sides of the box lid 2 each have a folded edge plate 21. The lower end of the folded edge plate 21 has a second notch 211 to form a second fastening portion 8. The second notches 211 at the lower ends of the two folded edge plates 21 can be correspondingly fastened to the first notches 171, thus forming a fastening relationship between the folded edge plate 21 and the second abutment plate 17.

[0035] Specifically, the connector 5 includes a buckle 51, which is disposed on the cover 2 and arranged on the left and right sides of the cover 2. The left and right side walls of the box body 1 have corresponding insertion holes for the buckle 51 to be inserted. Correspondingly, notches are provided on the folded edge 21 plate and the third mounting plate 33 to avoid interference with the buckle 51. The buckle 51 is common knowledge to those skilled in the art. The buckle 51 specifically includes a housing, a connector, and an elastic element. The connector is movably inserted into the housing and can be completely retracted within the housing. The elastic element is located within the housing and can drive a portion of the connector to protrude outside the housing, thus allowing the connector to be inserted into the holes of other components for locking. An operating port is provided on the housing, through which the connector can be moved to completely retract into the housing, disengaging the connector from the holes of other components for unlocking.

[0036] When installing the cover 2, move the buckle 51 to retract it, and fasten the second fastening part 8 at the lower end of the folded edge 21 plate on both sides of the cover 2 to the fastened part 7 of the second abutment plate 17 at the lower end of the box body 1 to achieve initial positioning. Then release the buckle 51, and under the action of the spring, the buckle 51 part is inserted into the insertion hole 19 to complete the installation of the cover 2. The operation is simple and easy to maintain.

[0037] Furthermore, refer to Figure 2 The box body 1 has a third abutment plate 18 extending inward from the upper edge of the opening, and the upper edge of the box cover 2 is provided with a flexible shock-absorbing strip 9, which can abut against the third abutment plate 18. The shock-absorbing strip 9 can be made of EVA sponge or flexible rubber strip, etc. In this embodiment, it is fixed to the box cover 2 by sponge, thereby playing a shock-absorbing role between the box cover 2 and the box body 1.

[0038] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
