Problems solved by technology

[0005] (3) The part that drives the ratchet to swing is the bevel wheel. After the ratchet enters the tooth groove, the bevel wheel is inserted between the ratchet rod and the housing. The bevel wheel is easily damaged and makes it difficult to pull out the bevel wheel.

Abstract

The invention discloses a parking mechanism and a vehicle. The parking mechanism comprises a housing, a parking gear, parking swinging arms, parking racks, an energy absorbing device and a driving device; the parking gear is provided with parking gear teeth; the parking swinging arms are rotationally arranged on the housing; the parking racks get close to or far away from the parking gear with the rotation of the parking swinging arms; the parking racks can move in the length directions of the parking racks; parking rack teeth are formed in the parking racks; the parking racks, the parking swinging arms and parking swinging arm shafts are multiple and are arranged in a one-to-one corresponding manner; the energy absorbing device is used for absorbing impact energy; and the driving device is used for driving the parking swinging arms to act synchronously. According to the parking mechanism, by improving tooth top structures of the parking gear and the parking racks and employing the movable characteristics of the parking racks, the problem of tooth interference between the parking gear and the parking racks is solved; and by adopting the energy absorbing device, the impact energy in the engagement process between the parking gear and the parking racks can be absorbed, and a perfect parking effect is obtained.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a parking mechanism and a vehicle. Background technique [0002] At present, a variety of models have been equipped with automatic parking mechanisms, and the most representative structure is the ratchet ratchet rod cone wheel type. The principle of parking is that the ratchet bar swings, and the single ratchet of the ratchet bar enters the tooth groove of the ratchet wheel, and then the bevel wheel squeezes and locks the ratchet bar so that the ratchet teeth block the ratchet wheel and cannot rotate, so as to achieve the purpose of parking. But there are three major problems with this structure: [0003] (1) The ratchet wheel and the ratchet teeth are prone to misalignment, and the ratchet cannot ensure that the ratchet teeth enter the tooth grooves accurately when parking. [0004] (2) When the vehicle is parked at a low speed, since the ratchet is in motion, the ratchet must colli...
