Problems solved by technology

[0004] However, in the process of pulling up the parking brake handle to make the pawl and the gear plate mesh, there will be a collision, which will make a "da da da" sound, which will affect the comfort, and the pawl can only stay In a limited number of cogs, it cannot stay between adjacent cogs. In this way, if the parking brake force corresponding to the previous cog is insufficient, it is necessary to apply a greater operating force to make the pawl stick. Into the rear cog to improve the parking braking force, affecting comfort; in addition, it is also difficult for female drivers, so that the parking braking force of the car is insufficient and there is a hidden danger of rolling

Embodiment Construction

[0027] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0028] In this disclosure, unless stated otherwise, the orientation words used such as "up and down" refer to up and down in the direction of gravity, and "inner and outer" refer to the inner contour defined for the corresponding component itself. and outside. The terms "first", "second" and the like used in the present disclosure are for distinguishing one element from another, and do not have sequence or importance. When the following description refers to the drawings, the same symbols in different drawings represent the same or similar elements unless otherwise indicated. In addition, it should be understood that the specific embodiments described in th...

Abstract

The invention relates to a parking mechanism and a vehicle, the parking mechanism comprises a parking handle (1), a base (2) and a hydraulic locking device (3), the parking handle (1) is provided with a handle end (12) and a connecting end (11), the handle end (12) and the connecting end (11) are opposite to each other, and the connecting end (11) is pivotally connected to the base (2); and the hydraulic locking device (3) comprises a piston (31), a piston rod (32), an oil storage cylinder (33) and a working cylinder (34), the oil storage cylinder (33) and the working cylinder (34) are hinged to the base (2) and are in fluid communication with each other, one end of the piston rod (32) is hinged to the connecting end (11), and a switch valve (35) is controlled to be opened or closed to allow or cut off flowing of hydraulic oil between the oil storage cylinder (33) and the working cylinder (34), so that the piston (31) can move or keep the position in the working cylinder (34) along with the rotation of the parking handle (1). Therefore, according to the parking mechanism, stepless adjustment of parking braking force can be achieved, the needed control force is small, and comfort is good.

Description

technical field [0001] The present disclosure relates to an automobile parking brake manipulation technology, in particular, to a parking mechanism and a vehicle. Background technique [0002] The car parking brake system can ensure the stable and reliable parking of the car after the car is parked. The parking brake handle, commonly known as the hand brake, is the operating handle of the parking brake system. [0003] In the related art, the parking brake handle is switched between the locked and unlocked states through the cooperation of the pawl and the gear plate, so as to realize the establishment and release of the parking brake force. [0004] However, in the process of pulling up the parking brake handle to make the pawl and the gear plate mesh, there will be a collision, which will make a "da da da" sound, which will affect the comfort, and the pawl can only stay In a limited number of cogs, it cannot stay between adjacent cogs. In this way, if the parking brake f...
