Abstract

The invention discloses a foot parking braking and unlocking mechanism which consists of a braking assembly, a ratchet wheel piece, a connecting piece, a pawl and a pedal assembly, wherein the ratchet wheel piece is mounted on the braking assembly through a main shaft; the upper edge of the ratchet wheel piece is connected with the transmission rod of the braking assembly; an arc-shaped groove is formed below the ratchet wheel piece; a track is arranged below the ratchet wheel piece; a guide column which is mounted on the braking assembly is inserted into the arc-shaped groove; a return spring is arranged between the guide column and the ratchet wheel piece; the upper side and the lower side of the track respectively incline upwards and downwards from front to back; the front ends of the upper side and the lower side of the track are connected in a crossing manner; the rear ends of the upper side and the lower side of the track are connected through a folded side; positioning concave points are arranged at the rear ends; a ratchet wheel is arranged on the lower edge of the ratchet wheel; one end of each of the connecting piece and the pawl is pivoted on the braking assembly; another return spring is arranged between the connecting piece and the pawl; a guide pin matched with the track is arranged at the other end of the connecting piece; the other end of the pawl is matched with the ratchet wheel; another return spring is arranged between the other end of the pawl and the guide column; the upper end of the pedal assembly is fixed with the ratchet wheel piece. According to the foot parking braking and unlocking mechanism, the structure is simple, and foot parking unlocking can be conveniently achieved.

Description

technical field [0001] The invention relates to a foot parking braking and unlocking mechanism of a vehicle. Background technique [0002] In the prior art, the parking brake includes a hand brake and a foot brake, the components of which are well known in the art, including mechanisms for locking and unlocking. Generally, the locking and unlocking of the mechanism is realized through the cooperation and disengagement of the ratchet and the pawl. For the hand brake, it is usually unlocked by pressing the button with the thumb. For the foot brake, the unlocking device is realized by manual action or by stepping on the foot twice, but the general device is more complicated. [0003] In view of this, the inventor specially improves the foot parking brake and unlocking mechanism, and this case results from this. Contents of the invention [0004] The purpose of the present invention is to provide a foot parking braking and unlocking mechanism, which is convenient to realize ...
