Novel adjustable armrest guide rail adopting plastic material structure

Abstract

The invention discloses a novel adjustable armrest guide rail adopting a plastic material structure, and relates to the field of seat armrests. The novel adjustable armrest guide rail comprises an upper armrest supporting base, a sliding mechanism and a lower armrest supporting base, wherein the upper armrest supporting base is fixedly mounted on the upper part of the sliding mechanism; the lowerarmrest supporting base is fixedly mounted on the lower part of the sliding mechanism; the upper armrest supporting base comprises armrest skin and an upper armrest framework; the armrest skin is fixedly connected to the upper surface of the upper armrest framework; the sliding mechanism comprises an upper guide rail, friction plates, a spring, a damping block and a lower guide rail; the lower armrest supporting base comprises a lower armrest framework; the upper guide rail and the lower guide rail are made of a PP+30% LGF long glass fiber reinforced polypropylene material; the friction platesand the damping block are made of a POM material. The novel adjustable armrest guide rail improves the problems that in the prior art, the consistency of an operating force during opening and closingoperation of an adjustable armrest sliding rail is difficultly guaranteed, a product is relatively heavy, the operating comfort is difficultly controlled and the like. The novel adjustable armrest guide rail has the advantages of the consistent operation force, no abnormal noise, light weight, environment friendliness, emission reduction and the like.

Description

Technical field [0001] The invention relates to the field of seat armrests, in particular to an adjustable armrest rail with a novel plastic material structure. Background technique [0002] At present, the automobile manufacturing industry is booming, family cars are rapidly popularized, and automobile users have higher requirements for the comfort and ease of operation of automobiles, and the convenient use of related structures. The more common armrests are adjustable and fixed. Among them, the fixed armrest can only provide flip, while the adjustable armrest can be adjusted freely in the length direction, which brings more choices and makes people more comfortable, can meet the needs of different customers, and can improve customer satisfaction. This structure is more popular and accepted by customers. [0003] Adjustable armrests used metal guide rails in the previous structure, which has heavy weight and large operating force. The opening or closing force is too large at th...
