Built-in double pin locking device of sliding rail of automobile seat

Abstract

The invention discloses a built-in double pin locking device of a sliding rail of an automobile seat, comprising a lock (1), a key (2), a fixed rail (01), a sliding rail (02) and a side plate (03). The built-in double pin locking device of the sliding rail of the automobile seat adopts the following technical proposal: the sliding rail is provided with the lock and the key; the lock is internally provided with two pins driven by a sliding core which is controlled by the key to move up and down; the bottom of a fixed rail groove is provided with a plurality of locking holes with the distance being 2 / 3 of the distance of the two pins; when in locking, the key is tripped every time, only one of the two pins is inserted into the locking holes of the bottom of the fixed rail groove so as to lock the sliding rail, therefore, the defects that the prior art has complex structure, easiness of control failure and unlocking, and no fine tuning function; and the provided built-in double pin locking device of the sliding rail of the automobile seat uses the characteristics of fine tuning function of the double pins and strong tear resistance of the round locking holes to achieve the purposes of fine tuning function, simple and firm structure, shock resistance, and control-failing and unlocking resistance.

Description

technical field [0001] The invention relates to a locking device for a slide rail of a car seat, in particular to a car seat which is used for manual car seat slide rails for locking and unlocking, which is convenient and reliable, can finely adjust the seat distance, and can resist impact and uncontrollable unlocking Built-in double pin locking mechanism for slide rails. Background technique [0002] The adjustment and locking of the front and rear positions of the car seat are divided into electric type and manual type according to the type of seat. The electric seat is to realize the adjustment and locking of the seat position through the electric driver; The wrench of the locking device on the chair slide rail is unlocked, and the seat position is adjusted by manpower, and then the wrench is released to lock the seat. There are two types of automotive manual seat locking devices in the prior art, the built-in claw type and the side-mounted claw type. Among them, the bui...

AI Technical Summary

Problems solved by technology

There are two types of automotive manual seat locking devices in the prior art, the built-in claw type and the side-mounted claw type. Among them, the built-in claw type device has the disadvantages of complex structure, complicated assembly process, low mechanical strength, and no fine-tuning function , the stroke of the position adjustment is difficult to control, and it will exceed the stroke with a little force, and it is difficult for the driver and passengers to adjust the seat to a comfortable position; the side-hanging claw device has too concentrated stress on the mechanism, which may easily lead to out-of-control unlocking in the event of a car collision There are also hidden dangers, and there is also the problem that there is no fine-tuning function, and the stroke of position adjustment is difficult to control.

To sum up, the existing technology has the problems and deficiencies of complex structure, easy out-of-control unlocking, and no fine-tuning function
