Problems solved by technology

At present, most new energy gearbox electronic parking mechanisms have insufficient structural flexibility, and the product life cycle is limited; and the mechanical unlocking mechanism is arranged at the worm of the parking motor. After the parking motor loses power, this unlocking method requires the driver. Mechanical unlocking can be implemented only when the vehicle is operated under the vehicle, which has low safety and poor comfort

Abstract

The invention discloses a mechanical unlocking mechanism for electronic parking. The mechanical unlocking mechanism for electronic parking comprises a parking cam assembly, a pawl assembly, a parkinggear, a cable assembly and an execution assembly; the parking cam assembly comprises a parking guide shaft and a parking cam; the parking cam is arranged on the parking guide shaft in a sleeving mode;arc-shaped protrusions are circumferentially arranged on the outer side of the parking cam, so that the pawl assembly is respectively at a first parking position where the parking gear is engaged anda second parking position where the parking gear is disengaged along with the rotation of the parking cam; one end of the cable assembly is connected with the execution assembly; the other end of thecable assembly is connected with the parking guide shaft; and the execution assembly drives the parking guide shaft to translate through the cable assembly so as to drive the pawl assembly to move from the first position to the second position. The mechanical unlocking mechanism for electronic parking provides an emergency mechanical unlocking function under the condition that a parking motor ispowered off, so that a driver is able to conduct mechanical unlocking manually in a cab instead of getting off the cab; and the safety performance is high, and the operation comfort is good.

Description

technical field [0001] The invention relates to the field of parking control, in particular to a mechanical unlocking mechanism for electronic parking. Background technique [0002] The gearbox electronic parking mechanism is a mechanism that prevents the vehicle from sliding or rolling backwards when the car is parked on the road or on a slope. At present, most new energy gearbox electronic parking mechanisms have insufficient structural flexibility, and the product life cycle is limited; and the mechanical unlocking mechanism is arranged at the worm of the parking motor. After the parking motor loses power, this unlocking method requires the driver. The mechanical unlocking can be implemented only when the vehicle is operated under the vehicle, which has low safety and poor comfort. Contents of the invention [0003] In view of the above problems, the present invention proposes a mechanical unlocking mechanism for electronic parking in order to solve or partially solve ...
