Steel ball assembling structure used for sliding rail assembly of automobile seat

Abstract

The invention discloses a steel ball assembling structure used for a sliding rail assembly of an automobile seat. The steel ball assembling structure comprises a simulated outer sliding rail used forbeing matched with an inner sliding rail, under the matching state, and a simulated steel ball space for accommodating a steel ball is formed between the simulated outer sliding rail and the inner sliding rail; and as for size configuration of the simulated outer sliding rail, the size of the simulated steel ball space is gradually decreased in the length direction of the simulated outer sliding rail, and the steel ball can be arranged in the simulated steel ball space with the minimum size in an interference embedded mode and can be arranged in the simulated steel ball space with the maximumsize in a clearance embedded mode. When the sliding rail assembly is assembled by adopting the steel ball assembling structure, the inner sliding rail, the steel ball and a steel ball retainer are loaded into the simulated outer sliding rail and are pushed from the large-size end of the simulated outer sliding rail to the small-size end of the simulated outer sliding rail, and then are pushed intoan actual outer sliding rail to finish assembling, so that assembling of the sliding rail assembly is simple and easy to conduct, and damage to the sliding rail assembly in the assembling process iseffectively avoided.

Description

technical field [0001] The invention relates to the field of car seat slide rail assemblies, in particular to a steel ball assembly structure for the car seat slide rail assembly. Background technique [0002] The car seat slide rail assembly includes an inner slide rail connected with the seat, an outer slide rail connected with the vehicle body, steel balls and a steel ball cage for fixing the steel balls. This paper refers to the outer slide rail as the actual outer slide rail, and its two outer plates are called the actual outer plate, so as to distinguish it from the simulated outer slide rail and the simulated outer plate in the following text. [0003] Please refer to figure 1 , the inner slide rail 01 is in the shape of "several", the actual outer slide rail 02 is in the shape of "concave", and the bottom of the inner slide rail 01 and the steel ball cage 04 are embedded in the actual outer slide rail 02. [0004] like figure 1 As shown, steel ball spaces for acco...

AI Technical Summary

Problems solved by technology

[0007] It can be seen that the process of embedding steel balls in the prior art requires a large assembly force, the assembly is more complicated, the assembly efficiency is low, and the labor cost required for assembly is high; Plastic deformation of the inner slide rail, which damages the quality of the inner slide rail assembly
