Problems solved by technology

[0005] Due to shock absorbers such as rubber gaskets or springs, only a part of the excitation force can be consumed, and a part or even a large part of the excitation force is still transmitted to the equipment, causing the equipment to shake. less effective

Embodiment Construction

[0048] The embodiment of the present application provides a shock absorber, which can be applied to instruments and equipment that require buffering and shock absorption, for example, can be applied to micro-electro-mechanical system (micro-electro-mechanical system, MEMS) micromirrors It can also be applied to MEMS micromirror all-optical switching switches. Whether it is applied to MEMS micromirror laser radar or MEMS micromirror all-optical switching switch, the shock absorber is used to stabilize the MEMS micromirror. Correspondingly, the MEMS micromirror can pass through the shock absorber fixed on the mounting table. For example, the shock absorber can be fixed on the installation platform first, and then the MEMS micromirror is fixed on the shock absorber. Using the shock absorber can improve the stability of the MEMS micromirror, and can prevent the MEMS micromirror from being subjected to external shocks. The excitation force affects the propagation path of light on ...

Abstract

The embodiment of the application discloses a shock absorber, which belongs to the field of shock absorber technology. The shock absorber includes a fixed seat, a movable table, a plurality of damping elastic members and damping liquid, wherein: each damping elastic member is respectively fixed with the fixed seat and the movable table, and is located between the fixed seat and the movable table. between the movable tables; the fixed seat and the movable table form an accommodating chamber, the damping fluid is located in the accommodating chamber, the fixed seat and the movable table are not in contact, so The gap between the fixed base and the movable table is within the target value range. By adopting the present application, the shock absorbing effect of the shock absorber on the shock absorbing component can be enhanced.

Description

technical field [0001] The present application relates to the technical field of shock absorption, in particular to a shock absorber. Background technique [0002] Equipment with relatively high stability requirements is usually not directly fixed on the installation platform, but rubber pads or springs for shock absorption are installed between the equipment and the installation platform. [0003] For example, lidar, which requires high stability, is usually installed on the luggage rack on the roof when it is applied to a self-driving car. Specifically, shock absorbers such as rubber pads or springs can be fixed on the roof rack, and the lidar is fixed on the shock absorbers. In this way, when the excitation force received by the roof rack is transmitted to the lidar, a part of the excitation force is used to overcome the shock absorber and consume, and then, it has a shock absorption effect on the lidar and improves the stability of the lidar . [0004] In the process ...
