The invention provides a quick-change bracket for an electric vehicle and the electric vehicle comprising the quick-change bracket. The quick-change support comprises a support body fixed to a vehicle beam; the first-stage locking mechanism is arranged on the support body, and the first-stage locking mechanism is provided with a first-stage cavity; the second-stage locking mechanism is arranged on the support body, the second-stage locking mechanism and the first-stage locking mechanism are arranged in a spaced mode, and the second-stage locking mechanism is provided with a second-stage cavity. And in the locking state, the first-stage locking piece is locked in the first-stage cavity by the first-stage mechanism, and the second-stage locking piece is limited in the second-stage cavity. In the process of switching from the self-locking state to the unlocking state, the unlocking of the second-stage locking piece is earlier than the unlocking of the first-stage locking piece. And in the process of switching from the self-unlocking state to the locking state, the limiting of the second-stage locking piece by the second-stage locking mechanism and the locking of the first-stage locking piece by the first-stage locking mechanism are synchronously carried out. And the secondary locking mechanism ensures that the battery pack is not easy to fall off. When locking is needed, operation is convenient, and the installation efficiency and the installation reliability of the battery pack can be improved.
本发明提供一种电动车辆用快换支架及包含其的电动车辆。快换支架包括:支架本体,固定于车梁;一级锁止机构,设置在支架本体上,一级锁止机构具有一级空腔;二级锁止机构,设置在支架本体上并与一级锁止机构间隔设置,二级锁止机构具有二级空腔。锁止状态时,一级锁止件被一级机构锁定在一级空腔内,二级锁止件被限位在二级空腔内。自锁止状态切换至解锁状态的过程中,解除对二级锁止件的限位先于解除对一级锁止件的锁定。自解锁状态切换至锁止状态的过程中,二级锁止机构对二级锁止件的限位和一级锁止机构对一级锁止件的锁定同步进行。二级锁止机构使得电池包不易脱落。需锁定时,操作方便,有利于提高电池包的安装效率和安装可靠性。
