"Z" shaped automotive handbrake lever against stuck unlock and cracked handle

Abstract

The invention discloses a Z-shaped automobile hand braking rod capable of preventing unlock catching and handle breakage. An unlock pushing rod is bent to be Z-shaped from a cylindrical rod, one end, connected with a brake rod mounting seat, of the unlock pushing rod is pressed to be flat, a first arc is arranged at the front end of a flat section, the radius of the first arc is equal to the width of the flat section, a second arc is arranged at the tail end of the flat section, the radius of the second arc is smaller than the width of the flat section, and an incline section between the second arc and the flat section is used for transition; a first clearance is formed among the flat section, the incline section and the inner wall of the handle, the parts of the unlock push rod, other than the flat section and the incline section, form a second clearance with the inner wall of the handle, and the second clearance is larger than or equal to two times of the first clearance. The Z-shaped automobile hand braking rod has a simple structure, is ingenious in design, and can effectively overcome the phenomena of difficulty in pressing an unlock button and local breakage of the handle in a conventional Z-shaped hand braking rod.

Description

technical field [0001] The invention relates to a hand brake lever in an automobile braking device, in particular to a "Z" shaped automobile hand brake lever. Background technique [0002] The State Intellectual Property Office disclosed a "hand brake lever for automobiles" on January 23, 2013, with a patent number of CN201220275772.2. The hand brake lever adopts a "Z" shape structure, so that when the hand brake lever is installed, it is shifted away from the shift lever to avoid interference with the shift mechanism and the hand brake lever blocks the shift panel buttons. [0003] The hand brake lever on the car is composed of a brake lever mounting base, an unlocking push rod (also called a mandrel) and a handle (also called a jacket), and the handle is covered outside the unlocking push rod. The front end of the unlocking push rod stretches out of the handle as an unlocking button, and the tail end of the unlocking push rod links to each other with the brake lever mount...

AI Technical Summary

Problems solved by technology

[0004] However, due to certain deficiencies in the design of the existing "Z"-shaped hand brake lever, the unlocking button is laborious to press or cannot be pressed, resulting in difficulty in unlocking; There is also a phenomenon of cracking, and the material used in the handle is consistent with the handle material of the existing straight hand brake lever, which greatly affects the overall performance of the hand brake lever and affects the comfort of driving.
