Automobile and sliding rail assembly of seat thereof

Abstract

The invention discloses an automobile and a sliding rail assembly of a seat thereof. The sliding rail assembly is bilaterally symmetric and comprises an upper sliding rail and a lower sliding rail extending in the front-back direction and an upper ball and a lower ball arranged between the upper sliding rail and the lower sliding rail; the lower sliding rail comprises a horizontal base plate, a first vertical side plate connected to the upper portion of the left edge of the horizontal base plate, and a first horizontal top plate connected to the right side of the upper edge of the first vertical side plate; the upper sliding rail comprises a first inclined plate and a second inclined plate; the extension line of the first inclined plate, the first vertical side plate and the extension lineof the first horizontal top plate are tossed to form an upper triangular region; the upper ball is arranged at the upper triangular region and makes point contact with the first inclined plate, the first vertical side plate and the first horizontal top plate, and the extension line of the second inclined plate, the horizontal base plate and the first vertical side plate are crossed to form a lower triangular region. The lower ball is located at the lower triangular region and makes point contact with the second inclined plate, the horizontal base plate and the first vertical side plate. The sliding rail assembly solves the problem that the seat vibrates when adjusted, and has the enough bearing capability.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a slide rail assembly of an automobile and a seat thereof. Background technique [0002] The bottom of the car seat is usually equipped with a slide rail assembly, so that the driver can adjust the position of the seat according to his own body shape, so as to ensure that he can sit on the seat in the most comfortable posture, so that he can easily operate the steering wheel, accelerator pedal and clutch etc. control parts. [0003] The existing typical car seat slide rail assembly includes a lower slide rail and an upper slide rail, the lower slide rail is fixed on the bottom surface of the vehicle body, the upper part of the upper slide rail is fixedly connected with the bottom of the seat, and the lower part of the upper slide rail is embedded in the lower slide rail And can slide along the slide rail. Balls are arranged between the upper slide rail and the lower slide r...

AI Technical Summary

Problems solved by technology

[0004] However, during the application process, it was found that when the seat position is adjusted forward and backward by using this kind of car seat slide rail assembly, there will be problems of seat sticking and left and right shaking

[0005] In view of this, it is a technical problem to be solved by those skilled in the art to develop a slide rail assembly of a car seat so that it can avoid the disadvantages of the seat being stuck and shaking from side to side during the adjustment process.
