Description
Technical Field
[0001] The utility model relates to the technical field of electric vehicles, in particular to a multi-stage buffering shock absorber for an electric vehicle. Background Art
[0002] Electric vehicles are electric-driven vehicles, also known as electric-driven vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Electric vehicles are usually referred to as vehicles that use batteries as energy sources and convert electrical energy into mechanical energy through controllers, motors and other components to control the current size to change the speed of the vehicle.
[0003] Electric vehicles will be bumpy when driving on bumpy roads, so existing electric vehicles are equipped with shock absorbers, but the existing electric vehicle shock absorbers still have the following shortcomings: 1. Ordinary shock absorbers are often simply equipped with a shock absorbing spring, so the general shock absorption effect is not ideal; 2. Existing electric vehicle shock absorbers are often exposed to the outside, and are easily damaged by stones brought up by tires during driving. In addition, the shock absorber is affected by muddy water or some gravel debris for a long time, which greatly reduces the shock absorption effect and service life. Therefore, we propose a multi-level buffer electric vehicle shock absorber. Utility Model Content
