Abstract

The invention discloses an electric slide rail of a vehicle seat. Left and right slide rails are in the same structure; the slide rail at a single side consists of a fixed lower track, a sliding upper track, a strip ball rack, a lead screw, a worm wheel box, a motor, a transmission shaft and a motor supporting plate; the sliding upper track and the fixed lower track are hooked together; four spaces formed between the sliding upper track and the fixed lower track are used for placing the strip ball rack; the lead screw is positioned in the middle space of the sliding upper track and the fixed lower track; two ends of the lead screw are fixed on the fixed lower track by using supporting blocks; the worm wheel box is arranged on the lead screw; a worm wheel in the worm wheel box is engaged with the lead screw; the top of the worm wheel box is embedded in an inner fixed groove of the sliding upper track; the rotating shaft of the motor is connected with the worm wheel; the motor and the transmission shaft are positioned on the motor supporting plate; and two ends of the motor supporting plate are fixed on the sliding upper track of the left and right slide rail structure. The motor drives the front and rear distance adjustment of the seat, so the electric slide rail is convenient and labor-saving, and the defects of mechanical and manual adjustment are overcome.

Description

The electronic slide rail of a kind of seat

Technical field

The present invention relates to a kind of slide rail of vehicle seat, the electronic slide rail of particularly a kind of seat.

Background technology

Existing car seat structure generally is a M/C, and it is loaded down with trivial details to operate.

Summary of the invention

The purpose of this invention is to provide the electronic slide rail of a kind of seat, the electronic slide rail dependence of this seat electric power carries out the fore-and-aft adjustment of seat, and is easy and simple to handle laborsaving.

The left and right sides of the present invention rail structure is identical, one-sided slide rail is by fixing lower railway, slip is got on the right track, the strip ball rack, leading screw, turbine box, electrical motor, transmission shaft and electrical motor supporting plate constitute, slip get on the right track and fixedly lower railway be hooked on together, four spaces storing strip ball racks that slip is got on the right track and fixedly formed between the lower railway, leading screw is arranged in to slide and gets on the right track and the fixing intermediate space of lower railway, the two ends of leading screw are fixed on fixedly on the lower railway with back-up block, leading screw is provided with turbine box, turbine in the turbine box and leading screw engagement, the top of turbine box is embedded in the internal fixation groove that gets on the right track that slides, the turning cylinder of electrical motor connects with turbine, electrical motor and transmission shaft are positioned on the electrical motor supporting plate, on the slip that the two ends of electrical motor supporting plate are fixed on left and right sides rail structure is got on the right track.

Principle of work of the present invention is: electrical motor just or reverse turn, by the turbine rotation in the transmission shaft drive turbine box, because turbine and leading screw engagement, turbine box slides before or after leading screw, and then drive to slide to get on the right track and move forward and backward, the seat that drives on it is adjusted longitudinal separation.

The invention has the beneficial effects as follows: convenient and strength-saving with the longitudinal separation adjustment of motor drives seat, overcome the shortcoming that the manipulator dynamic formula is adjusted.
