Built-in five-pin locking device for automobile seat slide rail

Abstract

The invention discloses a built-in five-pin locking device for an automobile seat slide rail, which comprises a lockset (1), a key set (2), a fixed rail (01) and a slide rail (02). In the invention, the slide rail is provided with the lockset and the key set, wherein five independent pins are arranged in the lockset; the claw plate of the key set drives the five pins of the lockset to perform an up-and-down implant movement; the slot bottom of the fixed rail is provided with lockholes with a plurality of circular holes and kidney holes being alternately arranged; and every time the slide rail is locked, three of the five pins of the lockset participate in the locking. The technical scheme of the standby two pins of the invention overcomes the problems and the defects of complex structure, high out-of-control tendency to unlocking, and no function of short pitch adjustment in the prior art; and the built-in five-pin locking device for the automobile seat slide rail provided by the invention has the advantages of simple structure, firm locking, shock resistance and low out-of-control tendency to unlocking, and has the function of short pitch adjustment.

Description

technical field [0001] The invention relates to a locking device for a car seat slide rail, in particular to a built-in five Pin locking device. 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 adjusted and locked by 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. [0003] 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 complex structure, complicated assembly process, and no short-distance adjustment function. It is difficult to control the stroke of the car, and it is difficult for the driver and passengers to adjust the seat to a comfortable position;...

AI Technical Summary

Problems solved by technology

[0003] 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 complex structure, complicated assembly process, and no short-distance adjustment function. It is difficult to control the stroke of the car, and it is difficult for the driver and passengers to adjust the seat to a comfortable position; the side-mounted claw device has the hidden danger of being out of control and unlocking when the car collides due to the excessive concentration of the mechanism stress, and there is also no short-distance adjustment function. , the problem that the stroke of position adjustment is difficult to control

Moreover, the existing locking device cannot guarantee complete and reliable locking under the condition of vibration and turbulence, and it is easy to unlock when a collision occurs.

Therefore, the prior art has the problems and deficiencies of complex structure, easy out-of-control unlocking, and no short-distance adjustment function
