This arrangement ensures that the mounting mechanism 31 is fixedly connected to the box cover 2. It should be noted that, in this embodiment, the bottom of the first mounting slot 21 represents the recessed side of the first mounting slot 21, so the mounting mechanism 31 is built into the first mounting slot 21, which can not only reduce the impact of external impact on the mounting mechanism 31, but also ensure the integrity of the box cover 2.

[0034] For details, please refer to Figure 1 and Figure 2The fastener mechanism 32 includes a mounting base 321 , an opening and closing plate 322 , an upper spring cover 325 , a lower spring cover 323 , a buffer spring 326 , a connecting shaft 327 and a hook 324 .

[0035] Among them, please refer to Figure 1 , Figure 2 and Figure 3 The mounting base 321 includes a first bottom plate 3211, and second connecting plates 3212 are arranged on both sides of the first bottom plate 3211 along the first direction. The two sides of the opening and closing press plate 322 are respectively movably riveted to the corresponding second connecting plates 3212, and the opening and closing press plate 322 can rotate on the mounting base 321. In this embodiment, the opening and closing press plate 322 includes a first side plate 3221, a second side plate 3222 and a hand-held plate 3223 arranged between the first side plate 3221 and the second side plate 3222. The first side plate 3221 and the second side plate 3222 are respectively movably riveted to the corresponding second connecting plates 3212, which means that when the hand-held plate 3223 is subjected to force, it can drive the first and second side plates 3222 to rotate.

[0036] For further information, please refer to Figure 1 , Figure 2 and Figure 6 The lower spring cover 323 is placed on the first bottom plate 3211, and the lower spring cover 323 includes a second bottom plate 3231.

[0038] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 6The upper spring cover 325 is connected to the cover body 3241, and the upper spring cover 325 includes a third bottom plate 3251. The third bottom plate 3251 has three sides along the third direction respectively provided with a sixth connecting plate 3252, a seventh connecting plate 3253 and an eighth connecting plate 3254, wherein the sixth connecting plate 3252 and the eighth connecting plate 3254 are respectively located between the second connecting plate 3212 and the lower spring cover 323, and the seventh connecting plate 3253 is located between the sixth connecting plate 3252 and the eighth connecting plate 3254, and the seventh connecting plate 3253 passes through the passage between the fourth connecting plate 3233 and the hook body 3242 and is buckled with the bottom of the second bottom plate 3231. The above settings are used to limit the moving trajectory of the hook 324, that is, to ensure that the hook 324 is hung.

[0039] It should also be noted that in this embodiment, the first direction and the second direction are perpendicular to each other, and the third direction is the opposite direction of the first direction, wherein the first direction is represented by L, the second direction is represented by A, and the third direction is represented by M. For details, please refer to Figure 1 It should also be noted that, in this embodiment, please refer to Figures 3 to 6 , B represents the battery box after the simulated cover is connected, so as to facilitate the display of the buckle assembly 3.

[0040] For connecting shaft 327, please refer to Figure 2 and Figure 6 Specifically, the connecting shaft 327 passes through the side of the opening and closing plate 322, the sixth connecting plate 3252, the third connecting plate 3232, the fifth connecting plate 3234 and the eighth connecting plate 3254, thereby ensuring that the various structures of the fastener mechanism 32 are linked accordingly, thereby fastening the connecting shaft 313.

[0041] In this embodiment, please refer to Figure 1 and Figure 3 The end of the box body 1 is concavely provided with a second mounting notch 11 facing the inside of the box body 1, the first mounting notch 21 is connected to the second mounting notch 11, and the first bottom plate 3211 is fixed to the second mounting notch 11, so that the fastener mechanism 32 is fixed to the second mounting notch 11. This design is mainly to prevent the fastener mechanism 32 from being subjected to external impact, avoid the influence of being unable to buckle, and also ensure that the fastener mechanism 32 can be accurately buckled with the bridge mechanism 31.

[0042] The operation of the battery box is described in detail below. First, the box cover 2 is connected to the opening of the box body 1. Then the operator holds the hand-held plate 3223 on the opening and closing button 322 and rotates it from the initial position toward the mounting mechanism 31, thereby driving the upper spring cover 325 and the lower spring cover 323 connected through the connecting shaft 327 to rotate accordingly. At this time, the hook body 3242 on the hook 324 is located above the buckling shaft 313, and the buckling mechanism 32 is in a pre-buckled state. For details, please refer to Figure 1 , Figure 3 and Figure 4 The operator then holds the hand-held plate 3223 and rotates it back to a certain angle. The return rotation is represented by rotating in the opposite direction of the above operation, so that the hook body 3242 contacts and latches with the buckle shaft 313. The operator then exerts force to continue the return rotation so that the hand-held plate 3223 returns to its initial position. During this process, the hook body 3242 on the hook 324 is gradually and firmly latched with the buckle shaft 313 under the cooperation of the cover body 3241, the buffer spring 326, the upper spring cover 325 and the lower spring cover 323. At this time, the fastener mechanism 32 is in a fastened state. When the hand-held plate 3223 returns to its initial position, the buffer spring 326 in the buffer cavity is firmly compressed by the inner wall of the cover body 3241 connected thereto. For details, please refer to Figure 4 , Figure 5 and Figure 6 After the above operations are completed, the box cover 2 is assembled with the box body 1. The operation process is simple and convenient, and the firmness of the assembly of the box cover 2 and the box body 1 is also guaranteed.

[0043] As for the operation of disassembling the battery box, the specific operation is as follows. Following the above content, the operator continues to hold the hand-held plate 3223 and rotates it from the initial position toward the mounting mechanism 31 to break the tension balance originally maintained, and the hook body 3242 gradually loosens the fastening of the buckling shaft 313 and gradually moves to the top of the buckling shaft 313. When the hook body 3242 is completely above the buckling shaft 313, the upper spring cover 325 and the lower spring cover 323 are rotated. Since the connecting shaft 327 passes through the side of the opening and closing plate 322, the sixth connecting plate 3252, the third connecting plate 3232, the fifth connecting plate 3234 and the eighth connecting plate 3254, the upper spring cover 325 and the lower spring cover 323 can be rotated accordingly, so that the hook 324 can be away from the buckling shaft 313, thereby realizing the removal of the battery cover. The process is also simple and convenient, which is convenient for the operator to replace the battery module in the battery box.
