Static expanding lifting device of automobile air bag

Abstract

The invention discloses a static expanding lifting device of an automobile air bag. The device comprises a lifting table face, a worm gear nut, a guide plate, a screw, a guide column, a lifting table support column, a press plate, a guide rail, a worm and a lifting table basic plate. A linear rolling bearing and an upper bearing seat are installed at the four corners and the center of the lifting table basic plate fixed on an experiment table face through the lifting table support column, a lower bearing seat is installed at the center position of the experiment table face, the worm gear nut adopts a bearing to be installed on the upper bearing seat and the lower bearing seat and is meshed with the worm installed on the experiment table face, the guide column is connected with the upper end of the screw and the lifting table face, the middle sections of the guide column and the screw are inserted in the linear rolling bearing and the worm gear nut to be matched, the lower ends of the guide column and the screw are inserted in a through hole on the experiment table face, the end face of one long side of the rectangular guide plate is vertically connected with the bottom face of the lifting table face, the guide rail is vertically fixed on the experiment table face, and the press plate is fixed on the guide rail to form a fixed sliding groove assembled with two ends of the guide plate in matching mode.

Description

technical field [0001] The invention relates to a lifting device capable of resisting shock and vibration. More specifically, it is a special-purpose auto airbag static deployment lifting device that can realize lifting and keep stable under the impact vibration generated by airbag deployment. Background technique [0002] As an important load-carrying and working platform for adjusting the position of related mechanisms, the lifting device is widely used in various experimental equipment. [0003] The current experimental lifting platform generally has the following three types: [0004] 1. Vertical lifting platform adopting the principle of screw transmission; [0005] 2. The scissor lift table adopts multi-bar scissor connection to realize folding and unfolding; [0006] 3. It is a lifting mechanism that combines the above two working principles. [0007] The first type can effectively control the lifting height and ensure the precision of the test bench, but the bear...
