Adjustable mechanical side wing structure

Abstract

An adjustable mechanical side wing structure comprises a driver, a worm mounting frame, a worm, a side wing supporting plate and a guide sliding way, wherein the driver is arranged on the outer side of the worm mounting rack, and a power output shaft of the driver is mounted on the worm mounting rack in a penetrating manner; the worm is arranged in the worm mounting frame and assembled on the power output shaft; the side wing supporting plate comprises a stroke adjusting part and a side wing supporting part arranged at the end of the stroke adjusting part, the stroke adjusting part is of an arc-shaped structure, teeth meshed with the worm are machined at the bottom of the stroke adjusting part, a sliding rail matched with the guide sliding way is machined on the stroke adjusting part, and teeth at the bottom of the stroke adjusting part of the side wing supporting plate are meshed with the worm after the side wing supporting plate is mounted on the worm mounting frame; and the guide slide way is arranged on the stroke adjusting part of the side wing supporting plate and is fixedly connected with the worm mounting frame. The side wing structure is small in occupied space, high in strength, simple in structure, convenient to install, few in manufacturing process, low in cost and large enough in stroke.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to an adjustable mechanical side wing structure. Background technique [0002] In the internal structure of the car seat, the side support of the seat back frame and the seat cushion frame is usually realized by welding steel wires and sheet metal parts, which has a poor supporting effect and has no adjustment function. In order to realize the adjustment of the side wings, there are many models on the market that use aerodynamic side wings for the seat side wing structure, but the aerodynamic side wing structure has problems such as insufficient travel and soft support, which can no longer meet the comfort requirements of drivers and passengers. requirements. [0003] Chinese patent CN 108045271 B discloses "an adjustable side wing structure". By introducing a worm gear screw mechanism, the side wing structure increases the travel range of the aerodynamic side wing structure a...

AI Technical Summary

Problems solved by technology

However, the wing structure still has the following problems: (1) the structure takes up a large space, and it cannot be applied to seats of many models due to the constraints of the seat frame space; (2) the structure strength of the wing is low, and the supporting effect is not good; (3) the wing The structure is too complicated, there are many transmission mechanisms, and the installation is difficult, and it is prone to abnormal noise, non-rotation, jamming and other phenomena during use, which increases the frequency of follow-up maintenance; (4) The stroke is not large enough (about 30mm) to meet the requirements of cutting-edge customers. Affect the comfort of the driver or passengers; (5) There are many manufacturing processes and high manufacturing costs
