The invention discloses a quick locking mechanism and a vehicle battery pack with the quick locking mechanism, the quick locking mechanism comprises a locking column and a locking sleeve, a first elastic piece enabling one end of the locking sleeve to be opened in the axial direction of the locking sleeve is arranged in the locking sleeve, and an unlocking expansion pin is arranged in a cavity ofthe locking column in a sliding mode in the axial direction of the locking sleeve; at least one through hole communicated with a cavity of the lock column is formed in the side wall of the lock column, a locking block is arranged in each through hole in a radial sliding mode, a limiting sliding groove corresponding to each locking block is formed in the unlocking expansion pin, and the length direction of each limiting sliding groove extends in the axial direction of the lock column. The locking block is provided with a limiting part matched with the limiting sliding groove and located in thelimiting sliding groove in a sliding mode, the groove depth of the limiting sliding groove is gradually increased from top to bottom, an opening communicated with the cavity of the locking column is formed in the lower end of the locking column, and the size of the opening is larger than that of the lower end of the unlocking expansion pin. And a second elastic piece is arranged between the top ofthe cavity of the lock column and the upper end part of the unlocking expansion pin.

    本发明公开了一种快锁机构及具有该快锁机构的车用电池包,该快锁机构包括锁柱、锁紧套,锁紧套内设置有使其一端沿锁紧套的轴向张开的第一弹性件,锁柱的空腔内沿其轴向滑动设置有解锁涨销,锁柱的侧壁上开设有至少一个与其空腔相连通的穿孔,每个穿孔内均径向滑动设置有锁止块,解锁涨销上开设有与锁止块相对应的限位滑槽,限位滑槽的长度方向沿着锁柱的轴向延伸,锁止块上具有与限位滑槽相适配且滑动位于限位滑槽内的限位部,限位滑槽的槽深由上至下渐变渐深,锁柱的下端部开设有与其空腔相连通的开口,开口尺寸大于解锁涨销的下端部尺寸,锁柱的空腔的顶部与解锁涨销的上端部之间设置有第二弹性件。
