Parking executor and automobile

Abstract

The invention discloses a parking executor and an automobile. The parking executor comprises a parking executor housing; a parking shaft and a driving mechanism are arranged inside the parking executor housing, wherein the driving mechanism is used for driving the parking shaft to rotate about the central axis of the parking shaft; the housing is provided with a push rod which is coaxially arranged together with the parking shaft in a sliding fit manner and under a condition that the push rod is limited in the circumferential direction; and the push rod is in threaded transmission connection with the parking shaft. The parking executor disclosed by the invention can transform the rotation motion of the parking shaft into linear motion, thereby effectively improving the control precision ofparking.

Description

technical field [0001] The invention belongs to the technical field of automobile parking actuators, and in particular relates to a parking actuator and an automobile. Background technique [0002] With the rapid development of the automobile industry, for safety and other considerations, many vehicles are equipped with parking systems, which are mainly divided into manual parking systems and electronic parking systems. Manual parking systems require a larger lock when parking. and the control difficulty increases when going up and downhill, and it cannot be connected with the vehicle network, so complex control cannot be realized. Electronic parking systems on the market are gradually increasing, but most electronic parking actuators control the rotation angle of the parking shaft. To realize the parking action, as in the CN201721433733.X parking mechanism and the vehicle, the motor is used to cooperate with the parking system. When the parking motor rotates, it drives the ...

[0002] With the rapid development of the automobile industry, for safety and other considerations, many vehicles are equipped with parking systems, which are mainly divided into manual parking systems and electronic parking systems. Manual parking systems require a larger lock when parking. and the control difficulty increases when going up and downhill, and it cannot be connected with the vehicle network, so complex control cannot be realized. Electronic parking systems on the market are gradually increasing, but most electronic parking actuators control the rotation angle of the parking shaft. To realize the parking action, as in the CN201721433733.X parking mechanism and the vehicle, the motor is used to cooperate with the parking system. When the parking motor rotates, it drives the action of the actuator to realize the locking and unlocking of the parking system, but this type of parking The car actuator realizes the parking action by rotating, the stroke is relatively small, and the control accuracy is insufficient. When it is in the unlocked or locked position, the position of the parking motor may move when it is subjected to an external force, causing a safety accident, and when the parking motor fails Unable to unlock mobile vehicle
