Universal slide rail for automobile seat

Abstract

The invention relates to the field of automobile parts, in particular to a universal slide rail for an automobile seat. The slide rail comprises an upper slide rail and a lower slide rail, ends of two side surfaces of the upper slide rail is curved outwardly and upwardly to form slide cores respectively, and the outer side surface and the inner side surface of each slide core are provided with ball slide grooves respectively. Ends of two side surfaces of the lower slide rail are curved inwardly and downwardly to form slide grooves matched with the slide cores. Upper and lower rows of balls are arranged between each slide groove and the corresponding slide core, the upper balls are arranged in the ball slide grooves of the inner side surfaces of the slide cores, and the lower balls are arranged in the ball slide grooves of the outer side surfaces of the slide cores. The slide cores are formed by upward and outward curving of the two lateral ends of the upper slide rail, the slide grooves matched with the slide cores are formed by inward and downward curving of the two lateral ends of the lower slide rail, and accordingly structural simplicity and convenience in processing are realized; the outer side surface and the inner side surface of each slide core are provided with the ball slide grooves in arc smooth connection, the balls are mounted in the ball slide grooves, and the balls at front and rear ends are isolated through ball isolation pipes, so that smooth movement of the slide cores in the slide grooves is realized.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a universal slide rail for an auto seat. Background technique [0002] The function of the car seat slide rail is to adjust the front and rear positions of the car seat and lock the seat at the same time. The car seat slide rails in the prior art can be divided into electric adjustment type and manual adjustment type according to the adjustment mode; left and right symmetrical type and asymmetrical type according to the structure, among them, the manual adjustment type and the front type of the electric horizontal drive gearbox Most of the slide rails adopt a symmetrical structure; the middle-mounted slide rails of the electric horizontal drive gearbox mostly adopt an asymmetric structure; the rolling parts matched with various slide rails are more complicated in specifications and varieties, and the assembly process is complicated, resulting in a large investment in molds, Waste of re...

AI Technical Summary

Problems solved by technology

The slide rail has good versatility and low cost; however, the forming process of the sliding core and the chute is complicated, and the assembly is inconvenient
