Abstract

The utility model discloses an automobile seat sliding device. A locking mechanism in the automobile seat sliding device comprises a linkage rod rotationally assembled along an axial line which extends forwards and backwards, a transmission plate hinged to a movable slide rail along the axial line which extends leftwards and rightwards and positioning lock grooves distributed at intervals in the front-and-back direction and arranged on fixed slide rails, wherein a U-shaped knob is fixedly connected and bridged between transmission plates of two fixed slide rails; the linkage rod and the transmission plates are arranged in parallel and at intervals; a locking tongue for overhanging outwards is fixedly arranged on the linkage rod; an unlocking spring is assembled between the linkage rod and the movable slide rail; a positioning baffle for stopping the rotation is assembled at the periphery of the linkage rod. When a seat moves forwards and backwards as required, an operator can uplift the knob in the vertical direction to enable the transmission plates fixedly connected to the knob to avoid the positioning baffle, meanwhile, the unlocking spring drives the linkage rod to rotate, and the locking tongue under the driving of the linkage rod is pulled out from one positioning locking groove. Therefore, the working reliability and stability of the locking mechanism in the whole sliding device are improved.

Description

A kind of automotive seat slide device

Technical field

The utility model relates to a kind of automotive seat slide device.

Background technology

At present, front-row seats bottom on commercially available automobile is all equipped with slide device, to regulate the front and back position of seat on major-minor operator seat by slide device, especially concerning riding in the chaufeur on main driving position, can regulate according to the bodily form of chaufeur the front and back position of seat on main driving position, so that controls such as the better steering dish of chaufeur, pedal and shifter bars.And existing slide device comprises the lockout mechanism assembling on two spaced sliding track mechanisms in left and right and each sliding track mechanism, each sliding track mechanism comprises that fixed rack and the front and back guiding movement on the Floor-board frame that is fixed on vehicle body is assemblied in the movable slide rail on fixed rack, and lockout mechanism comprises lock pin and the retracing spring assembling on movable slide rail, on fixed rack, offer a row for the dowel hole of the spacing plug-in mounting of lock pin and for drawing the traction bracing wire of two lock pin synchronization actions on movable slide rail, in use, the personnel on front-row seats of being sitting in are by pulling traction bracing wire, so that lock pin overcomes the pressure power of retracing spring and is pulled out in dowel hole from fixed rack, lockup state between movable slide rail and fixed rack is removed, operating personal can promote smoothly seat and move forward and backward, after moving into place, operating personal unclamps traction bracing wire, makes lock pin spacing being inserted in dowel hole again under the pressure power effect of retracing spring, to lock the relative position between movable slide rail and fixed rack.But because traction bracing wire is under service life and flexible impact, long-term use there will be the lax phenomenon of traction bracing wire, so when chaufeur pulls traction bracing wire, lock pin on two movable slide rails usually can not synchronization action, so that the front-row seats on automobile can not move forward and backward smoothly, thereby the reliability of service of automotive seat slide device and service life are reduced, affect the normal driving of operating personal and take.
