High and low rail dual rotation axis unlocking system

Abstract

The invention provides a sliding rail double-rotating shaft unlocking system. The sliding rail double-rotating shaft unlocking system comprises a high-side sliding rail assembly and a low-side slidingrail assembly, wherein the high-side sliding rail assembly and the low-side sliding rail assembly both comprise upper sliding rails and lower sliding rails which are in sliding connection and are provided with unlocking mechanisms; the unlocking mechanisms of the high-side sliding rail assembly and the low-side sliding rail assembly are connected by a handle lever assembly; the unlocking mechanism of the low-side sliding rail assembly comprises an unlocking support arranged on the upper sliding rail; the unlocking support is provided with a rotating shaft perpendicular to the sliding rail andcan rotate around the rotating shaft; the lower side end of the handle lever assembly is pressed down on the unlocking support; and an elastic resetting mechanism is arranged between the unlocking support and the upper sliding rail. The layout problem that the horizontal level of the sliding rails is inconsistent is solved by replacing a traditional single shaft with double rotating shafts in thesliding rail double-rotating shaft unlocking system; meanwhile the sliding rail double-rotating shaft unlocking system has relatively strong expansibility; the unlocking mechanism of the high-side sliding rail can follow the existing design; and the synchronous unlocking of the high-side rail and low-side rail can be satisfied only by making certain improvements on the unlocking mechanism of thelow-side sliding rail.

Description

technical field [0001] The invention relates to an unlocking mechanism for slide rails of automobile seats, in particular to an unlocking system with high and low rails and double rotating shafts. Background technique [0002] The rise of seven-seater cars has increased the requirements for the design and layout of the slide rails of the second row of seats. It is often required that the slide rails adopt a horizontal and unequal layout, so as to meet the needs of the fuel tank layout of the vehicle, the beautiful placement of the slide rails, and the prevention of stumbling. [0003] There are many deficiencies in the traditional single-axis unlocking system of slide rails: 1. The inclined rotation axis is difficult to ensure the synchronization of slide rail unlocking; 2. There is internal stress in the unlocking process; 3. The bushing is severely worn and its life is shortened; 4. The unlocking system is easy Stuck; 5. Poor external expansion.

AI Technical Summary

Problems solved by technology

[0010] Aiming at the various defects of the current traditional car seat high and low rail unlocking mechanism, the present invention provides a high and low rail dual rotation axis unlocking system, which not only solves the problem of synchronous unlocking when the heights of the two slide rails are different, but also has better scalability. Strong, we only need to make some improvements to the unlocking structure of the slide rail on the low side to meet the synchronous unlocking of the high and low rails
