In this embodiment, a working process of the battery replacement connection device and the vehicle is as follows:
the vehicle body fixing seat 12 in the vehicle body locking module 1 and the vehicle body are fixed to each other, and the battery fixing seat 231 in the battery locking module 2 and the battery are fixed to each other.
When the battery needs to be mounted on the vehicle body, the battery is moved to the position of the vehicle body locking module 1, and the vehicle body fixing pin 11 is pushed to be inserted into the opening at the upper end of the telescopic cavity of the battery fixing seat 231 aligned with the vehicle body fixing pin 11. Since the outer diameter of the end of the vehicle body fixing pin 11 is increased to have an inclined slope and the upper end of the telescopic cavity of the battery holder 231 has the trapezoidal opening 2313, the vehicle body fixing pin 11 can be easily inserted until the circular platform portion 112 of the vehicle body fixing pin 11 is completely inserted into the trapezoidal opening 2313 and the vehicle body fixing pin 11 is inserted in place. Then insert in transmission hole 2321 and with the cooperation of transmission post 2111 through driving tool 3, promote the jack-up prevent changeing lantern ring 221, rotate the sleeve and drive transmission post 2111 and rotate afterwards, drive whole fixed pin locking axle 211 and rotate, under the screw-thread fit on flexible chamber and fixed pin locking axle 211, fixed pin locking axle 211 rotates and rises until being located upper limit position. In the process that the fixing pin locking shaft 211 rises, the conical head at the upper end of the fixing pin locking shaft 211 is in contact fit with the inclined surface section 2312 of the telescopic cavity, the cylindrical locking conical pin 212 is gradually pushed into the inner cavity and finally abuts against the inclined surface of the vehicle body fixing pin 11, and the mutual locking of the vehicle body locking module 1 and the battery locking module 2 is completed. Then the driving tool 3 is pulled out, at this time, under the action of the anti-rotation spring 222, the anti-rotation collar 221 is tightly attached to the lock body fixing cover 232, and friction provided by the knurled surface ensures that the anti-rotation collar 221 cannot rotate, so that the fixing pin locking shaft 211 cannot rotate, the position of the fixing pin locking shaft 211 is locked, and the fixing pin locking shaft is kept in a state of being locked with the vehicle body fixing pin 11. At this time, if an external force (for example, gravity, vibration and the like) separating the battery from the vehicle body occurs, the cylindrical locking taper pin 212 is limited by the inclined surface section 2312 of the telescopic cavity and cannot return, and the vehicle body fixing pin 11 is tightly clamped, so that the vehicle body fixing pin 11 cannot exit from the inner cavity, and the battery and the vehicle body are locked firmly enough.
When the battery needs to be detached from the vehicle body, the driving tool 3 is inserted into the transmission hole 2321 and is engaged with the transmission post 2111, the jacking rotation-preventing collar 221 is pushed, and the fixing pin locking shaft 211 is rotated in the opposite direction to the above, and similarly, the fixing pin locking shaft 211 is rotated and displaced downward up to the lower limit position. In the moving process, the cylindrical locking taper pin 212 is gradually not abutted by the inclined surface section 2312, and the release of the vehicle body fixing pin 11 is completed. At this moment, the battery is separated from the vehicle body, and in the process that the vehicle body fixing pin 11 exits from the inner cavity, the inclined surface section 2312 of the telescopic cavity can freely slide and does not have a limiting effect on the vehicle body fixing pin 11, so that the vehicle body fixing pin 11 can be directly pulled out from the battery fixing seat 231, and the unlocking of the battery and the vehicle body is completed.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
