The invention belongs to the technical field of new energy vehicles, and particularly relates to a parking mechanism manual unlocking device, an unlocking method, a speed reducer and a new energy vehicle. The manual unlocking device of the parking mechanism comprises an unlocking adapter shaft provided with an unlocking through hole, the unlocking through hole comprises an arc-shaped first part and a second part used for driving a parking gear shifting shaft to rotate, and a first meshing point and a second meshing point are arranged in the second part; the angle between the first meshing point and the second meshing point in the rotating direction of the gear shifting coupling shaft is larger than the angle of the parking gear shifting shaft rotating from the parking state to the parking releasing state. One end of the unlocking rocker arm is connected with the unlocking rotating shaft, and the other end of the unlocking rocker arm extends in the direction away from the rotating center of the unlocking adapter shaft. Manual unlocking can be achieved under the emergency condition, and higher reliability is achieved.

    本发明属于新能源汽车技术领域,尤其涉及一种驻车机构手动解锁装置、解锁方法、减速器和新能源车。本发明的驻车机构手动解锁装置,包括:解锁转接轴,设置有解锁通孔,所述解锁通孔包括圆弧形的第一部分和用于带动驻车换挡轴转动的第二部分,所述第二部分中设置有第一啮合点和第二啮合点,所述第一啮合点与第二啮合点之间在换挡转接轴转动方向的角度大于驻车换挡轴从驻车状态转动到解除驻车状态的角度;解锁摇臂,一端与解锁转轴相连,另一端朝远离解锁转接轴转动中心的方向延伸。本发明不仅可以实现紧急情况下手动解锁,并且具有更高的可靠性。
