The invention discloses an expansion bead type quick-change locking mechanism, a locking device, a battery pack and an electric automobile, the expansion bead type quick-change locking mechanism comprises a lock base, a plurality of balls and a driving assembly, and the balls are arranged on the lock base and can move in the lock base; the driving assembly pushes the balls to draw close to each other so as to abut against the concave portion on the peripheral side of the lock shaft to lock the lock shaft, or the driving assembly is far away from the balls so as to enable the balls to be far away from the concave portion to unlock the lock shaft, the lock shaft is inserted into the lock base, and the driving assembly pushes the balls to gather and abut against the concave portion on the side face of the lock shaft to lock the lock shaft. When unlocking is needed, the driving assembly is far away from the balls, the balls are far away from the lock shaft so as to unlock the lock shaft, the device is simple in structure, the number of unlocking and locking steps is small, the lock shaft can be rapidly locked or unlocked, the multiple balls lock the lock shaft at the same time, and the locking stability of the lock shaft can be enhanced.

    本发明公开了一种涨珠式快换锁止机构、锁止装置、电池包和电动汽车,涨珠式快换锁止机构包括锁基座、多个滚珠和驱动组件,多个滚珠设于锁基座并能够在锁基座内运动,驱动组件推动多个滚珠以实现多个滚珠相互靠拢以抵接锁轴周侧的凹部使锁轴锁止或者驱动组件远离多个滚珠使多个滚珠远离凹部以解锁锁轴,锁轴插入锁基座中,驱动组件推动多个滚珠聚拢,抵接于锁轴侧面凹部,以将锁轴锁定,需要解锁时,驱动组件远离滚珠,滚珠远离锁轴,以解锁锁轴,本装置结构简单,解锁和上锁的步骤少,能快速地将锁轴锁定或解锁,多个滚珠同时锁定锁轴,能够加强对锁轴锁定的稳定性。
