Abstract: A mechanical unlocking mechanism for electronic parking is provided, which comprises a parking cam assembly, a pawl assembly, a parking gear, a pull cord assembly and an actuating assembly. The parking cam assembly comprises a parking guide shaft and a parking cam. The parking cam is sleeved on the parking guide shaft. The outer side of the parking cam is provided with an arc protrusion along a circumferential direction, so that with the rotation of the parking cam, the pawl assembly is in a first position where the parking gear parks in and a second position where the parking gear parks out. One end of the pull cord assembly is connected with the actuating assembly, and the other end of the pull cord assembly is connected with the parking guide shaft. The actuating assembly drives, via the pull cord assembly, the parking guide shaft to translate, thereby driving the pawl to move from the first position to the second position. The mechanical unlocking mechanism according to the present disclosure provides an emergent mechanical unlocking function when the parking motor is powered off, and the driver can perform manual mechanical unlocking in the cab without getting off the vehicle, so it has high safety and good operation comfort.
