Abstract: An electronic parking mechanism that includes a parking cam assembly, a pawl assembly and a parking gear. The parking cam assembly includes a parking guide shaft and a parking cam that is sleeved on the parking guide shaft, and one side of the parking cam is provided with an arc protrusion along a circumferential direction so that as the parking cam rotates, the pawl assembly is in a first position where the pawl assembly parks in the parking gear and a second position where the pawl assembly parks out the parking gear, respectively. The pawl assembly includes a pawl and a pawl shaft, an upper part of the pawl contacts the parking cam, the pawl shaft is provided on a side of the pawl that can rotate around the pawl shaft.

Abstract: A reducer casing structure is disclosed, which comprises a front casing, a rear casing and a connecting column; the front casing and the rear casing are sealedly connected to form therein a cavity structure for accommodating a reducer; the connecting column is provided in the cavity structure and is detachably or partially detachably connected between the front casing and the rear casing, the connection mode of the connecting column with the front casing and the rear casing is bolt connection or integrated casting, the connecting column is used to improve connection strength of the reducer casing structure, reduce casing vibration and improve NVH performance of the reducer. The reducer casing structure according to the present disclosure reduces the deformation of the front casing and the rear casing of the reducer during operation, and improves the NVH of the reducer itself or the whole power assembly; moreover, the reducer casing structure is easy to install and occupies less space.
