Abstract

The invention discloses a slide rail for a seat of a car. The slide rail comprises a left slide rail and a right slide rail with same structures; the slide rail at each side consists of a fixed rail, a sliding rail, strip-shaped ball frames, a locking device, a connection shaft lever and a control lever, wherein the fixed rail is fixed on a baseboard of the car; the sliding rail is arranged on the fixed rail in a sliding manner; a seat can be fixed on the sliding rail; the strip-shaped ball frames are arranged at the upper inner side and the lower outer side of the space of the fixed rail; slide plates which extend outwards and slantwise are arranged at two sides of the sliding rail; the slide plates are arranged between two strip-shaped ball frames of respective space in a sliding manner; the locking device consists of a locking fork, a pin shaft and a reset spring; the locking fork passes through two pin holes at side via the pin shaft and then is pivoted on the sliding rail; the reset spring is penetrated on the pin shaft; the locking fork is linked with the control lever; and prongs of the locking fork are inserted in the inner wall of the gliding rail, the locking holes of the slide plates and an open locking groove on a suspension wall of the fixed rail. The slide rail can slide smoothly and has high structure strength and even stress; and when collision occurs, the sliding rail is not stripped from the fixed rail.

Description

Sliding rail of automobile seat

Technical field

The present invention relates to a kind of sliding rail of automobile seat.

Background technology

The patent No. is ZL200710147256.5, the patent of invention that a kind of name is called " sliding means of seat rail " is disclosed, from Fig. 4 (b) of ZL200710147256.5 as can be seen, the locking hole (11) of its underpart track (5) and the avoidance hole (12) of upper track (6) are enclosed, structure like this, the height of lower tracks (5) is increased, and then the interior space that " sliding means of seat rail " occupied increase and increase automobile single-piece weight.

Summary of the invention

The purpose of this invention is to provide a kind of sliding rail of automobile seat, the disclosed technical scheme of the structure of this sliding rail of automobile seat and ZL200710147256.5 relatively, it is little and alleviate the advantage of automobile single-piece weight to have an interior space that occupies.

The left and right sides of the present invention rail structure is identical, one-sided slide rail is made up of trapped orbit, sliding rail, strip ball rack, blocking device, connection axostylus axostyle and control lever, trapped orbit is fixed on the base plate of automobile, sliding rail is slidingly installed on the trapped orbit, and sliding rail is fixed on automotive seat on the sliding rail by the connecting bore on it; The structure of trapped orbit is, both sides have the space of interior under shed, the last inboard in each space is provided with the strip ball rack, the following arranged outside in each space has the strip ball rack, the sliding rail both sides have the slide plate of outside oblique extension, and these two slide plates are slidingly installed between two strip ball racks in space separately; Offer the locked groove of arrangement on the suspended wall of trapped orbit inwall, lock in the blocking device is pitched the inwall of pairing sliding rail and the position of slide plate offers lockhole, the inboard outer wall of the trapped orbit two ends limiting block that extended internally, the slide plate of cooresponding sliding rail is outward extended with block, the setting of trapped orbit two end limiting blocks and sliding rail block can make sliding rail can not skid off from trapped orbit two ends.

Blocking device is made up of lock fork, bearing pin and retracing spring, the lock fork is the U type, the lock fork is articulated on the sliding rail with two pin-and-holes that bearing pin passes the side, retracing spring is located on the bearing pin, one side of retracing spring is stuck in lock and sticks, another side is stuck on the sliding rail, and the shank of the key activity of lock fork is plugged in the jack of control lever afterbody, and the prong of lock fork is plugged in the lockhole of the inwall of sliding rail and slide plate and in the locked groove on the trapped orbit suspended wall; The two ends that connect axostylus axostyle are articulated on the sliding rail of left and right sides slide rail, control lever is the U type, the top ends of U type forward, the top, two side middle parts of control lever offers draw-in groove, connects axostylus axostyle and is entrapped in the draw-in groove, and two ends that connect axostylus axostyle are equipped with retracing spring, one side of retracing spring is stuck on the control lever, another side is stuck on the sliding rail, and control lever two afterbodys offer horizontal jack, and the shank of the key activity of lock fork is plugged in the jack of control lever afterbody.

Principle of work of the present invention is:

1, during usual state, control lever is the level of state, the lock fork is under the effect of retracing spring, the prong of lock fork is plugged in the inwall of sliding rail and the slide plate lockhole and in the open locked groove on the trapped orbit suspended wall, sliding rail is locked on the trapped orbit, and then the seat that will be fixed on the sliding rail locks.

2, in the time will moving forward and backward seat, upwards pull control lever, at this moment, control lever serves as that axle rotates to connect axostylus axostyle, the tail down of control lever is moved, the shank of the key that drives the lock fork moves down, and then to drive the lock fork be that axle rotates with the bearing pin, at this moment, the prong of lock fork breaks away from inwall and the lockhole of slide plate and the open locked groove on the trapped orbit suspended wall at sliding rail, release between sliding rail and the trapped orbit, health drives seat and moves forward and backward, and then the drive sliding rail moves, after the position is determined, decontrol control lever, lock fork and control lever reset under the effect of retracing spring, lock between sliding rail and the trapped orbit.

The invention has the beneficial effects as follows:

1, locked groove on the trapped orbit suspended wall is that three side sealing closes, an opening, be open locked groove, the lock fork is when screwing in or screw out locked groove, the lock fork can enter locked groove from the opening of locked groove, and traditional circumferential closed locked groove, lock fork need could screw in or screw out locked groove from the side under the situation of not interfering with closed edge, the lock fork needs bigger motion space in this case, higher locked groove dimensional accuracy, therefore three side sealing locking groove design can farthest reduce the sectional dimension of sliding rail and trapped orbit under the prerequisite of proof strength, greatly reduces manufacture difficulty, reduce manufacturing cost and material cost, saved the space in the car.

The mounting interface of 2, sliding rail is integrated in design control lever and blocking device has reduced number of parts, has controlled the accumulated error that is produced because of part manufacturing and assembling effectively, has improved the single-piece quality of fit.
