Title:

TRANSMISSION SHIFTING AND PARKING STRUCTURE AND NEW ENERGY VEHICLE

Document Type and Number:

WIPO Patent Application WO/2022/142148

Kind Code:

A1

Abstract:

Disclosed in the present invention are a transmission shifting and parking structure and a new energy vehicle. The transmission shifting and parking structure comprises a rotary drive mechanism, a shifting rotation arm, a shifting fork, a shifting actuator, a drive guide shaft, a parking rotation arm, a parking push rod assembly, and a parking actuator; the rotary drive mechanism is used for driving the drive guide shaft to rotate; one end of the shifting rotation arm and one end of the parking rotation arm are fixed on the drive guide shaft and rotate along with the drive guide shaft; the other end of the shifting rotation arm is provided with a cylindrical pin; the cylindrical pin moves along a shifting fork slot provided on the shifting fork along with the rotation of the shifting rotation arm and drives the shifting fork to move; a plurality of positions corresponding to gear positions are provided on the shifting fork slot; the other end of the parking rotation arm is hinged with the parking push rod assembly; and the parking push rod assembly drives the parking actuator to achieve a parking action. The solution employs a set of mechanisms to realize both parking and shifting actions, thereby saving the arrangement space of shifting and parking mechanisms, reducing the number of drive sources and parts, and reducing costs.
