• a parking pawl, which is provided in the vehicle in a way that it is rotatable around a fixed axis, and an engagement end of the parking pawl is located between the position limiting member and the parking gear, and is rotatable to a parking position where it is engaged with the parking gear;
• a push rod assembly which comprises:
• a push rod, which is provided with a pushing part that can abut between the parking pawl and the position limiting member,
• a push block, which is slidably provided on the push rod, and
• an elastic member, which is connected between the pushing part and the push block;
• a swinging drive member, which is capable of swinging back and forth around a swinging axis, a swinging end of the swinging drive member can be hinged to the push block to push or pull, via the push block, the pushing part to move by means of the elastic member, and by pushing the pushing part the parking pawl can be driven to rotate so that the engagement end is rotated to the parking position;
• and
• a position restoring member, which is capable of providing a position restoring force to the parking pawl, so that the engagement end can be disengaged from the parking position after the pushing part is pulled,
• the push block is a sliding sleeve slidably sleeved on the push rod, and an outer surface of the push block is provided with a pair of hinged parts that are provided on opposite sides;
• the swinging drive member comprises a pair of swinging parts, and a swinging end of each of the pair of swinging parts can be hinged respectively to radially opposite sides of the push block through one of the hinged parts,
• wherein the parking device is configured such that when the parking is to be released, the swinging drive member drives the push block to swing, and the push block pulls the pushing part of the push rod by means of the elastic member, so that the position restoring force of the position restoring member acts on the parking pawl.
