[0033] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0034] like Figures 1 to 7As shown, a locking assembly 10 of an embodiment is used to lock the cover 30 and the box body 20 of the box 1. The locking assembly 10 includes an elastic reset member 100, a rotating member 200 and a clamping member 300; the elastic reset member 100 is movably sleeved on the rotating member 200, the first end of the rotating member 200 at least partially protrudes from the mounting groove 31 of the cover 30, and the second end of the rotating member 200 is detachably connected to the clamping member 300 through the first mounting hole 31a of the mounting groove 31; a locking hole 21 corresponding to the clamping member 300 is opened at the bottom of the box body 20, when the rotating member 200 rotates, the clamping member 300 is located at a first preset rotation angle, and the clamping member 300 passes through the locking hole 21 and abuts against the bottom of the box body 20; the clamping member 300 is located at a second preset rotation angle, the clamping member 300 overlaps with the locking hole 21, and the clamping member 300 is separated from the box body 20.

[0035] It can be understood that since the elastic reset member 100 is movably mounted on the rotating member 200, and the first end of the rotating member 200 at least partially protrudes from the mounting groove 31 of the cover body 30, the elastic reset member 100 is located in the mounting groove 31, and the operator can rotate the first end of the rotating member 200 in the mounting groove 31, and can press down the elastic reset member 100, and when the external force is removed, the elastic reset member 100 can be automatically reset; and since the second end of the rotating member 200 is detachably connected to the snap-in member 300 through the first mounting hole 31a of the mounting groove 31, the rotating member 200 and the snap-in member 300 are detachable, and compared with the integrated structure, the convenience of disassembly and assembly of the locking assembly 10 is achieved.

[0036] When the locking member 300 is in the locked state, the locking member 300 is locked and the locking member 300 is in the locked state.

[0037] like Figures 4 to 6As shown, in one embodiment, a mounting fixing portion 32 is formed in the mounting groove 31, and the elastic reset member 100 is sleeved on the mounting fixing portion 32; the mounting fixing portion 32 is formed with a second mounting hole 32a connected to the first mounting hole 31a, and the rotating member 200 passes through the second mounting hole 32a and the first mounting hole 31a in sequence. In this embodiment, the mounting fixing portion 32 added in the mounting groove 31 further ensures the stability of the installation of the elastic reset member 100, and ensures that when the elastic reset member 100 and the rotating member 200 are locked together, the elastic reset member 100 does not shift in position, thereby improving the locking effect of the locking assembly 10; because the mounting fixing portion 32 is provided with a second mounting hole 32a, the rotating member 200 is sequentially installed in the second mounting hole 32a and the first mounting hole 31a, further ensuring the stability of the rotating member 200 installed on the cover body 30.

[0038] like Figure 1 and Figure 5 As shown, in one embodiment, the rotating member 200 includes a rotating protrusion 210 and a rotating connection part 220 connected to each other, and the elastic reset member 100 is sleeved on the rotating connection part 220, and the rotating connection part 220 passes through the first mounting hole 31a, so that the rotating protrusion 210 is rotatably arranged in the mounting groove 31. In this embodiment, since the rotating protrusion 210 is rotatably arranged in the mounting groove 31, the rotating protrusion 210 can be rotated in the mounting groove 31; and since the elastic reset member 100 is sleeved on the rotating connection part 220, the rotating protrusion 210 is pressed against the elastic reset member 100, and the elastic reset member 100 can be automatically reset in the mounting groove 31, so as to ensure that when locking, the self-reset of the elastic reset member 100 can improve the locking effect of the locking assembly 10.

[0039] like Figure 1 and Figure 6 As shown, in one embodiment, the clamping member 300 includes a mounting connection portion 310 and a clamping portion 320 connected to each other; the mounting connection portion 310 is detachably connected to the rotating connection portion 220, and the clamping portion 320 is disposed at the bottom of the box body 20 through the locking hole 21. In this embodiment, due to the detachable connection between the rotating connection part 220 and the installation connection part 310, on the one hand, it is ensured that the clamping part 300 and the rotating part 200 can be replaced separately when damaged, reducing maintenance costs, and on the other hand, it is improved. The efficiency of disassembly and assembly of the clamping part 300 and the rotating part 200 is improved; and due to the connection between the rotating connection part 220 and the installation connection part 310, the clamping part 320 passes through the locking hole 21 and is arranged at the bottom of the box body 20, so that the clamping part 320 can rotate under the drive of the rotating connection part 220, and the clamping part 320 passes through the locking hole 21 of the box body 20 and abuts against the bottom of the box body 20, so that the clamping part 320 can be connected to the bottom of the box body 20 by rotation, thereby realizing the locking of the cover body 30 and the box body 20.

[0040] like Figure 2 and Figure 6 As shown, in one embodiment, the locking assembly 10 further includes a fastener 400, which is connected to the fixing hole 221 of the rotating connection part 220 through the through hole 311 of the mounting connection part 310. The rotating connection part 220 and the mounting connection part 310 are connected by the fastener 400 to ensure the firmness of the connection between the rotating connection part 220 and the mounting connection part 310. At the same time, it is convenient for the operator to disassemble and replace the rotating connection part 220 and the mounting connection part 310 separately during maintenance. In this embodiment, the fastener 400 is a screw. In other embodiments, the fastener 400 is a bolt.

[0041] Furthermore, in one of the embodiments, the rotating connection part 220 is provided with a snap-fitting groove, and the mounting connection part 310 is provided with a snap-fitting block corresponding to the snap-fitting groove. When the rotating connection part 220 and the mounting connection part 310 are connected, the snap-fitting block is snapped into the snap-fitting groove, thereby improving the firmness of the connection between the rotating connection part 220 and the mounting connection part 310.

[0042] In one embodiment, the elastic reset member 100 is a compression spring member, which is elastically deformed when pressed by an external force, and has the ability to automatically reset when the external force is removed. In this embodiment, the self-reset force provided by the compression spring member ensures the tight fit between the box body 20 and the cover body 30, thereby improving the locking effect of the locking assembly 10.

[0043] In one embodiment, the locking assembly 10 further includes a buffer pad 500, which is disposed between the rotating protrusion 210 and the elastic reset member 100. In this embodiment, since the buffer pad 500 is disposed between the rotating protrusion 210 and the elastic reset member 100, on the one hand, direct contact between the elastic reset member 100 and the rotating protrusion 210 is avoided, and the wear of the elastic reset member 100 and the rotating protrusion 210 during rotation is reduced; on the other hand, the direct extrusion of the rotating protrusion 210 by the automatic reset of the elastic reset member 100 is reduced, thereby increasing the service life of the elastic reset member 100 and the rotating protrusion 210.

[0044] The present disclosure also provides a box 1 for storing battery assembly modules. The box 1 includes a box body 20, a cover body 30 and the locking assembly 10 described in any of the above embodiments. The cover body 30 is movably covered on the box body 20. The bottom of the box body 20 is provided with a receiving groove 22 connected to the locking hole 21. The receiving groove 22 is used to place the locking portion 320. Figures 4 to 7In the present embodiment, the cover body 30 is connected to the box body 20 via a rotating shaft, so that the cover body 30 can be rotatably covered on the box body 20. Since a receiving groove 22 is provided at the bottom of the box body 20, the clamping part 320 is in contact with the bottom of the box body 20, and the clamping part 320 can be located in the receiving groove 22, ensuring that the clamping part 320 is firmly fitted to the bottom plate of the box body 20, preventing the clamping part 320 from being offset at the bottom of the box body 20, thereby improving the locking effect of the clamping part 320 and the box body 20.

[0045] like Figure 3 and Figure 7 As shown, in one embodiment, the engaging portion 320 includes a locking block 321 and a limiting protrusion 322 connected to each other, and a groove 23 is formed in the receiving groove 22; when the locking block 321 is located at the first preset rotation angle, the locking block 321 is engaged in the receiving groove 22, and the limiting protrusion 322 is engaged in the groove 23. In this embodiment, the locking block 321 is located at the first preset rotation angle, the box body 20 and the cover body 30 are in a locked state, the locking block 321 is engaged in the receiving groove 22 at the bottom of the box body 20, and the limiting protrusion 322 is engaged in the groove 23. Under the action of the elastic reset member 100, the stability of the clamping and fixing of the limiting protrusion 322 and the groove 23 is improved, and the locking effect of the locking assembly 10 is further improved.

[0046] In one embodiment, the locking block 321 and the limiting protrusion 322 are integrally formed to ensure the firmness of the connection between the locking block 321 and the limiting protrusion 322, ensure the stability of the limiting protrusion 322 when it is engaged with the groove 23, and further improve the locking effect of the locking assembly 10.

[0047] The present disclosure also provides an electrical device, including a box 1 and a battery assembly module.

[0048] Compared with the prior art, the present invention has at least the following advantages:

[0049] 1) Since the elastic reset member 100 is movably sleeved on the rotating member 200, and the first end of the rotating member 200 at least partially protrudes from the mounting groove 31 of the cover body 30, the elastic reset member 100 is located in the mounting groove 31, and the operator can rotate the first end of the rotating member 200 in the mounting groove 31 and press down the elastic reset member 100. When the external force is removed, the elastic reset member 100 can be automatically reset; and since the second end of the rotating member 200 passes through the first mounting hole 31a of the mounting groove 31 and is detachably connected to the clamping member 300, the rotating member 200 and the clamping member 300 are detachable, and compared with the integrated structure, the convenience of disassembly and assembly of the locking assembly 10 is achieved.

[0050] 2) After the rotating member 200, the elastic reset member 100 and the snap-on member 300 are assembled on the cover body 30, they need to cooperate with the locking hole 21 opened at the bottom of the box body 20 to realize the closing and opening of the cover body 30 and the box body 20; when locking, the snap-on member 300 is adjusted to be at the second preset rotation angle by rotating the rotating member 20 to ensure that the snap-on member 300 coincides with the locking hole 21, and then the elastic reset member 100 is pressed to make the snap-on member 300 pass through the locking hole 21, and finally the rotating member 200 is rotated to make the snap-on member 300 at the first preset rotation angle to ensure that the snap-on member 300 abuts against the bottom of the box body 20. When the external force is removed, under the action of the elastic reset member 100, the snap-on member 300 is more closely attached to the bottom of the box body 20, avoiding the snap-on member 300 from being separated from the bottom of the box body 20 due to external force, thereby improving the locking effect of the locking assembly 10.

[0051] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
