Abnormal sound prevention automobile seat control device

Abstract

The invention discloses an abnormal sound prevention automobile seat control device, which relates to the technical field of automobile accessories, and comprises two groups of inner slide rails and outer slide rails matched with each other, and further comprises two locking mechanisms and a control handle. The locking mechanism comprises a locking long rod, a rocker arm, a locking plate and a torsion spring; the rocker arm is fixedly arranged at the position, close to the front end, of the long locking rod; a through hole matched with the control handle is formed in the rocker arm; a silencing bush is arranged in the through hole in a sleeved mode; the locking plate is fixedly arranged at the rear end of the locking long rod and is opposite to the fixing plate; the torsion spring sleevesthe locking long rod; one end of the torsion spring is connected with the locking plate, and the other end of the torsion spring is connected with the fixing plate; the control handle is of a U-shapedstructure, and the two ends of the control handle penetrate through the corresponding through holes respectively and then are connected with the outer slide rails through fixing pin shafts; a lockinggroove matched with the locking plate is formed in the inner slid rail; and a through groove for the locking plate to penetrate through is formed in the position, corresponding to the locking plate,of the outer slide rail.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto seat control device for preventing abnormal noise. Background technique [0002] Slide rails for car seats are widely used in various types of car seats, and are functional devices for adjusting the front and rear positions of seats. Usually, a driver's seat and a copilot passenger's seat are at least housed on a vehicle body, and various types of slide rails are equipped at the middle part where the same seat is connected to the vehicle body. Among them, the lever-type seat slide rail assembly is widely used in various miniature passenger cars because of its simple structure and convenient processing. [0003] But because the two round bars of the handle of the lever type seat slide rail assembly and the elliptical hole of the rocking arm are clearance fits, when the car is running, especially when the road condition is bad, the two round bars of the handle follow th...

Problems solved by technology

[0003] But because the two round bars of the handle of the lever type seat slide rail assembly and the elliptical hole of the rocking arm are clearance fits, when the car is running, especially when the road condition is bad, the two round bars of the handle follow the movement of the vehicle body. Ups and downs, it also swings up and down in the oval hole of the rocker arm, collides with the inner section of the oval hole and produces abnormal noise
