Electric folding and unfolding device based on plurality of connecting rods

Abstract

The invention relates to an electric folding and unfolding device based on a plurality of connecting rods. The electric folding and unfolding device comprises a motor, the motor is connected with two gear sector systems, the two gear sector systems are respectively connected with a connecting rod mechanism, a driving structure of the motor is connected with input shafts of the two gear sector systems, an output shaft is connected with the connecting rod mechanisms, gear sectors are limited through sliding grooves, a limit switch is arranged, a right side driving rod rotates clockwise, an upper part is controlled to move, a left side driving rod rotates anticlockwise, a lower part is controlled to move, the connecting rod mechanisms can be unfolded forwards, sliding blocks connected with the connecting rod mechanisms move forwards, limiting blocks are connected to the sliding blocks, the limiting blocks are matched with an upper part limiting structure and a lower part limiting structure, and a tension spring and a pressure spring lock the connecting rod mechanisms. The electric folding and unfolding device can be applied to automotive interior products and is suitable for the internal layout of an instrument board; when the device is in use, the occupied space is small, the appearance is attractive, automatic stretching out is achieved, and the functionality of the instrument board is increased while the comfort is not damaged; and when the device is not in use, the device can be hidden in the interior of the instrument board.

Description

technical field [0001] The invention belongs to the technical field of automobile interior decoration, and in particular relates to an electric folding and opening device realized by using multi-links. Background technique [0002] At present, most of the internal layouts of automobile dashboards are fixed. This kind of layout takes up a lot of space, and the space cannot be used flexibly. It cannot meet the increasing diversified functional needs of people in the future, and the comfort is poor. There is no folding mechanism in the traditional dashboard. Therefore, it is necessary to develop an electric folding and opening mechanism, which is stretched out when in use, and folded and retracted when not in use. It takes up little space, has a compact structure, and increases the function of an automobile dashboard. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art, and provide an electric...
