[0093] Please refer to Fig.11 The second sleeve 740 is a columnar structure with a through groove, and the second sleeve 740 includes three second right-angled edges 741 and two first rounded edges 732 arranged vertically; one of the second right-angled edges 741 of the second sleeve 740 is clamped in the angle between the flip cover 500 and the second bracket 200, and is fitted and connected with one end of the second bracket 200; the second rounded edge 742 is arranged on the side away from the second bracket 200 and facing the flip cover 500.

[0094] It is understandable that when the flip cover 500 drives the connector 15 to be pulled out of the slot 141 and automatically flipped, when the first right-angled side 731 of the first sleeve 730 contacts the right-angled side of the connecting piece, and the second right-angled side 741 of the second sleeve 740 contacts the right-angled side of the flip cover 500, the rotation of the flip cover 500 will be restricted, thereby ensuring that the rotation angle of the flip cover 500 is in place and is 90°.

[0095] The first sleeve 730 and the second sleeve 740 can be made of the same component, and the angles at which the two are set can be adjusted.

[0096] The first sleeve 730 and the flip cover 500 can be separately provided or integrally formed. The second sleeve 740 and the second bracket 200 can be separately provided or integrally formed.

[0097] Optionally, a plurality of torsion springs 720 , first sleeves 730 , and second sleeves 740 may be disposed at intervals.

[0098] Of course, in some embodiments, the rotating assembly 700 may also adopt a rotating shaft and a third connecting part and a fourth connecting part sleeved on the rotating shaft, the third connecting part is connected to the flip cover 500, and the fourth connecting part is connected to the second bracket 200; when the flip cover 500 is flipped, the flipping action of the flip cover 500 can also be achieved.

[0099] Furthermore, in order to prevent the flip cover 500 from rotating out of position when automatically flipping, a limiting plate may be installed on the side of the second bracket 200 away from the flip cover 500 .

[0100] The working principle of the bracket 17 and the battery box 010 in this embodiment is:

[0101] Please refer to Figure 2 When the battery box 010 needs to be recharged, the cover 13 is removed; the handle is lifted to lift the flip cover 500 upward to a certain height, at which time the spring 310 is reset and the second bracket 200 and the flip cover 500 are simultaneously moved upward until the flip cover 500 drives the connector 15 to be pulled out of the slot 141 of the battery management module 14; please refer to Fig.12 and Fig.13 After the flip cover 500 drives the connector 15 to be pulled out of the slot 141, the flip cover 500 automatically flips 90 degrees under the elastic force of the torsion spring 720, and the first sleeve 730 and the second sleeve 740 simultaneously prevent the flip cover 500 from rotating out of position when automatically flipping.

[0102] Please refer to Figure 3 and Figure 4 After the flip cover 500 is turned over, the connector 15 below the flip cover 500 faces the window, and the external operator recharges the battery cells inside the battery by inserting the recharging device connector into the connector 15 through the maintenance window 121.

[0103] After the operation is completed, the operator can flip the flip cover 500 downward by 90° through the handle, press the handle 600 downward until the connector 15 is inserted into the slot 141 of the battery management module 14, and finally install the maintenance cover 13.

[0104] In summary, the bracket 17 proposed in the utility model is provided with a second bracket 200 and a first bracket 100 that can move relatively, so that the flip cover 500 can be lifted up and the connector 15 can be pulled out from the slot 141 of the battery management module 14; by providing a rotating assembly 700, the flip cover 500 is rotated relative to the bracket 17 to flip over, thereby realizing the charging work in the battery box 010 through the maintenance window 121, reducing the workload and operating difficulty of the charging work, facilitating later maintenance, and reducing maintenance costs.

[0105] The battery box 010 proposed in the present invention reduces the area of ​​the maintenance window 121 by providing the bracket 17 , thereby greatly reducing the influence of the maintenance window 121 on the sealing and strength of the battery box 010 .

[0106] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
