Abstract

The invention discloses a battery damping device for an electric automobile. Thebattery damping device comprises a box body and a battery rack arranged in the box body, wherein the battery rack comprises an upper plate and a lower plate, a battery pack is fixed between the upper plate and the lower plate, the side edge of the upper plate is connected with the inner side wall of the box body through a first elastic component, the lower plate is connected to the inner wall of the bottom of the box body through a second elastic component, a sliding groove is formed in the side surface of the lower plate, a sliding damping assembly is fixed to the inner wall of the box body, and the sliding damping assembly slides in the sliding groove. According to the device, vibration is reduced in the vertical direction, and through the combined action of the sliding groove and the sliding damping assembly, the good damping effect is achieved in the horizontal direction.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a battery damping device for electric vehicles. Background technique [0002] A pure electric vehicle (Blade Electric Vehicles, BEV) is a vehicle that uses a single battery as an energy storage power source. [0003] The advantage is that it is relatively simple and mature, and it can be charged wherever there is a power supply. [0004] However, the electric vehicle battery pack is composed of multiple batteries stacked in series. During use, it often encounters large vibrations, causing the lithium battery core to vibrate inside the battery case, and the vibration will also cause metal fatigue, causing the device to Some rigid bodies on the battery will crack and damage the device, resulting in damage to the lithium battery and reducing the service life of the lithium battery. Contents of the invention [0005] The object of the present invention is to ...
