Abstract
The present application relates to the field of swapping batteries of electric vehicles, particularly to a quick locking-unlocking assembly. The present application aims at solving the problem in the prior art that each locking mechanism of current electric vehicle power battery has too many parts and sophisticated structure, occupying larger space and thus increasing cost in manufacturing the electric vehicles. The quick locking-unlocking assembly of the application includes: a first sliding block and a second sliding block slidably connected to the electric vehicle body, a retaining sheath fixed to the outer shell of the power battery, a first spring and a second spring for forcing the first and second sliding blocks to move closer to each other, a bolt capable of extending through the retaining sheath and the first and second sliding blocks, and a third spring forcing the bolt away from the vehicle body. Further, the bolt is provided with a cam, by rotating which the first and second sliding blocks are forced to separate away from each other. Thus, the bolt is able to leave the electric vehicle under effect of the third spring. Accordingly, the quick locking-unlocking assembly o…
