The two rotating rods are arranged between the two connecting plates and are respectively arranged at opposite ends of the connecting plates. The rotating rods are rotatably connected relative to the connecting plates. Figure 5 As shown, a slot is provided on the cover body 14, and the slot is in an arc shape. The slot is used to install a rotating rod, and the rotating rod can rotate in the slot. At the same time, the opening at the upper end of the slot is less than 180 degrees, that is, the width of the slot opening is smaller than the diameter of the rotating rod, so that the rotating rod will not easily fall out of the opening at the upper end of the slot, so that the connection between the connecting rod 33 and the cover body 14 is more stable; and the two ends of the other rotating rod pass through the connecting plates on both sides and are rotatably connected to one end of the locking block 32, so that one end of the connecting rod 33 is rotatably connected to the cover body 14 relatively, and the other end is rotatably connected to the locking block 32, that is, the connecting rod 33 and the locking block 32 can both be rotatably connected relative to the cover body 14. In this embodiment, a hook 34 is provided at one end of the lock block 32 away from the connection with the connecting rod 33, that is, the upper end of the lock block 32 is rotatably connected with the connecting rod 33, and the lower end of the lock block 32 is provided with a hook 34. The limiter 17 is arranged on the box body 13 at the lower end of the cover body 14. Since the rotation path of the lock block 32 is long, when the lock block 32 rotates toward the box body 13, the hook 34 at the lower end of the lock block 32 can completely hook the limiter 17. When the lock block 32 is rotated toward the cover body 14, the lock block 32 can be tightened, so that the connection between the lock portion 19 and the limiter 17 is relatively tight.

The upper end of the reinforcing rib 26 is in contact with the lower wall of the connecting block 24, and the two ends along the extending length direction are respectively in contact with the side walls of the box body 13 and the side walls of the clamping block 25. The reinforcing rib 26 can strengthen the structural strength of the connecting block 24; the support blocks 27 are symmetrically arranged on both sides of the reinforcing rib 26. The support block 27 is a triangular structure. The upper end of the support block 27 is connected to the lower end of the connecting block 24, and the side end of the support block 27 is connected to the side wall of the box body 13. The support block 27 is used to support the connecting block 24. The support block 27 cooperates with the reinforcing rib 26 to enhance the connection strength between the connecting block 24 and the box body 13, so as to prevent the connecting block 24 from being easily disconnected from the box body 13 due to constant force, which is beneficial to enhancing the structural strength and service life of the battery box 12.

In this embodiment, there are two sealing ring grooves, which are arranged at intervals, and one of them is arranged at the bottom of the sealing portion 28, which can better seal and prevent external water vapor from entering the battery box 12 from the fitting connection surface between the box body 13 and the cover body 14.

[0065] Further, such as Figure 7 As shown, the sealing portion 28 is provided with two sealing annular grooves, namely the first annular groove 21 and the second annular groove 35. The first annular groove 21 is arranged at the upper end of the second annular groove 35. The first annular groove 21 is arranged at the upper end position of the sealing portion 28, and the second annular groove 35 is arranged at the lower end position of the sealing portion 28. The first annular groove 21 and the second annular groove 35 are arranged at intervals. Sealing rings 29 are provided in the first annular groove 21 and the second annular groove 35, so as to have a sealing effect at both the upper and lower ends of the sealing portion 28 and improve the sealing performance.

[0066] Further, such as Figure 7As shown, the outer diameter of the second annular groove 35 is larger than the outer diameter of the first annular groove 21, and a water retaining portion 38 is provided between the first annular groove 21 and the second annular groove 35. The side surface of the water retaining portion 38 is an inclined surface, and the upper end of the water retaining portion 38 is connected to the lower end of the first annular groove 21, and the lower end of the water retaining portion 38 is connected to the upper end of the second annular groove 35. The outer diameter of the lower end of the water retaining portion 38 is larger than the outer diameter of the second annular groove 35, and the lower end of the water retaining portion 38 protrudes outward relative to the second annular groove 35, and in the vertical direction, it has a limiting effect on the sealing ring 29 in the second annular groove 35, increases the stability of the sealing ring 29 in the second annular groove 35, and at the same time, can play a waterproof role in the vertical direction, can prevent water vapor from surging upward, and play the effect of maze sealing; and the water retaining portion 38 is an inclined surface, and water vapor will flow downward along the inclined surface of the water retaining portion 38 , thereby increasing the barrier property of water vapor flowing upward into the box body 13; and a first convex ring 36 is provided at the upper end of the first annular groove 21, and a second convex ring 37 is provided at the lower end of the first annular groove 21, the upper end of the water retaining portion 38 is connected to the second convex ring 37, the outer diameter of the upper end of the water retaining portion 38 is the same as the outer diameter of the second convex ring 37, the outer diameter of the first convex ring 36 is larger than the inner diameter of the first annular groove 21, the outer diameter of the second convex ring 37 is larger than the outer diameter of the first convex ring 36, the first convex ring 36 and the second convex ring 37 limit the upper and lower ends of the first annular groove 21, thereby limiting the sealing ring 29, so that the sealing ring 29 can be relatively fixed in the first annular groove 21, increasing the sealing property, thereby achieving a tortuous sealing effect at the first annular groove 21, and then improving the sealing effect, so that the waterproof effect of the battery box 12 is better.
