Embodiment 1

[0038] Please refer to figure 2 , the upper lock body 11 is a barrel-shaped structure with a closed top, an open bottom end, and a hollow interior. The lower lock body 12 is a cylindrical structure with a closed top end, an open bottom end, and a hollow interior. The top of the lower lock body 12 is located inside the upper lock body 11, and the unlocking device 20 is located inside the lower lock body 12, surrounding the lower lock body 12. The top end of the lower lock body 12 is provided with a plurality of matching holes 121 penetrating the side wall from the inside to the outside, and the bottom end of the lower lock body 12 is installed on the battery pack beam 40 through the fastening nut 50 .

[0039] Please refer to figure 2 , Figure 4 , 6 -7. The locking and unlocking device 20 includes a spring 21 , a small ball 22 , a guide rod 23 , a bearing rod 24 and a push rod 25 .

[0040] See Figure 4 , the upper part of the guide rod 23 is a cylindrical structure, a...

Embodiment 2

[0051] Please refer to image 3 and Figure 5 , 8 The difference between this embodiment and the first embodiment lies in: first, the locking device 20 further includes an ejection block 26 , and the ejection block 26 is installed on the top of the guide rod 23 . The ejection block 26 is an approximate cylindrical structure, and its diameter is slightly smaller than the diameter of the top of the lower lock body 12 . The ejection block 26 can move up and down inside the lower lock body 12 . The top of the ejection block 26 is provided with a second spring mounting hole 262, the second spring mounting hole 262 has the same function as the first spring mounting hole 231, and is used to install one end of the spring 21, and the side of the ejection block 26 is provided with a uniform The distribution of the second small ball bearing surface 263 inward slightly sunken, the effect of the second small ball bearing surface 263 and the first small ball bearing surface 232 is also th...
