At this time, the steel ball 53 is held by the frustoconical screw portion 58 so as not to be retracted, and protrudes from the outer peripheral surface of the fixed sleeve 51 so as to be engaged with the retracted bayonet 41 of the fixed sleeve 4.
Wherein, the diameter of the outer periphery of the steel ball 53 of the fixed shaft sleeve 51 is larger than the inner diameter of the inner contracting bayonet 41. And, the inner diameter of the second end of the stroke through hole 57 is smaller than the diameter of the steel ball 53 to ensure that the steel ball 53 does not roll out of the second end of the stroke through hole 57.
The height of the steel ball 53 exceeding the second space 14 is equal to the depth of the inner retracted opening 41 sunken in the first space 13, so that adjacent battery pack components can be tightly stacked, and the whole space is reduced.
The battery 2 in this embodiment wraps up a plurality of orderly arranged cells by welding and mechanical connection. The connecting end plate 1 is formed by aluminum alloy section bars or aluminum alloy through die casting. The screw assembly 5 is attached to the end plate.
When the screw 52 is rotated clockwise by 360 degrees, the steel balls 53 will extend outwards, and the fixing shaft sleeve 51 in the screw assembly 5 of one battery pack assembly is matched with the steel balls 53 to be mutually aligned and clamped with the fixing sleeve 4 of the other adjacent battery pack assembly.
When the screw 52 is rotated counterclockwise by 360 degrees, the steel balls 53 can be retracted inward, so that the fixing boss 51 can be inserted into the base 3 or pulled out from the base 3 without resistance.
When the module is installed, the steel balls 53 are kept in a contracted state, the module is placed at the specified position of the base 3, then the screw rod 52 is rotated clockwise, and when the steel balls 53 extend out, the steel balls can be locked with the fixed sleeve 4 connected in the base 3, so that the module is fixed in the base 3. Rotating the screw 52 anticlockwise, the steel ball 53 will be loosened from the fixing sleeve connected in the base 3 when it is contracted, and the module is disconnected from the base 3.
