[0029] This utility model consists of an upper connecting part, an upper sleeve, a lower sleeve, and a lower connecting part connected in sequence to form a detachable intermediate mounting structure. Multiple intermediate mounting structures are used to fix the battery pack to the vehicle frame. A second sealing structure and a third sealing structure are set to ensure a double seal between the upper sleeve and the lower connecting part, thereby ensuring the safety and reliability of the battery pack.

[0030] In this embodiment, as Figure 3 As shown, the upper connecting part 1 has a first outward folded surface 11 near the upper sleeve 2. The upper sleeve 2 has a first protrusion 21 protruding to the left and right sides in the middle.

[0035] In this embodiment, as Figure 4As shown, a fifth step 33 is horizontally arranged on the inner surface of the lower sleeve 3, away from the upper sleeve 2, from the fourth step 32. A sixth step 432 is arranged on the outer surface of the third insertion part 43, which abuts against the fifth step 33. The sixth step 432 is located on the side of the third step 431 away from the lower sleeve 3, and the bottom surface of the battery pack abuts against the sixth step 432. In addition, a first end 34 and a second end 35 are respectively provided at the upper and lower ends of the lower sleeve 3. The upper surface of the first end 34 abuts against the lower bottom surface of the first protrusion 21, and the inner surface of the second end 35 abuts against the inner surface of the second arc-shaped groove 421. The outer surface of the fourth sealing ring 632 abuts against the outer surface of the second end 35, which can better fix the fourth sealing ring 632.

[0036] In this embodiment, as Figure 4 and 5 As shown, the inner diameter d1 of the upper sleeve 2 is the same as the inner diameter d3 of the lower connecting part 4, and the inner diameter d2 of the lower sleeve 3 is greater than the inner diameter d1 of the upper sleeve 2.
