Electric motor coach power battery fixing device

Abstract

The invention discloses an electric motor coach power battery fixing device, and mainly relates to the field of new energy vehicles. The electric motor coach power battery fixing device comprises a carrier. A battery holder is installed in the carrier. A power battery pack is fixedly installed in the battery holder. The carrier and the battery holder are each of a box-shaped structure with top openings. Damping springs are connected between the inner side wall of the carrier and the outer wall of the battery holder. Cushion plates are arranged at the bottom of the side face of the carrier andprovided with installing holes. The carrier is fixedly installed on a vehicle chassis through the cushion plates and the installing holes. The top of the carrier is provided with a protection cover. The protection cover protects the battery holder inside. The protection cover is fixed to the carrier through bolts. The electric motor coach power battery fixing device has the advantages of having agood damping function, being capable of greatly reducing the vibration on power batteries when a vehicle passes by a bumpy road section and protecting the power batteries.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a fixing device for a power battery of an electric bus. Background technique [0002] The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. It is mainly different from the starter battery used to start the car engine. Valve-port sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries are mostly used. [0003] With the development and maturity of technology, new energy vehicles are widely put into use, and after continuous improvement and experimentation, the installation position of the power battery is fixed on the chassis of the vehicle, which is convenient for maintenance and installation, and this installation position also determines The power battery has to experience the sa...

Problems solved by technology

[0003] With the development and maturity of technology, new energy vehicles are widely put into use, and after continuous improvement and experimentation, the installation position of the power battery is fixed on the chassis of the vehicle, which is convenient for maintenance and installation, and this installation position also determines The power battery has to experience the same movement and experience as the car body. Electric buses often need to travel at high speeds for long-distance operation, and sometimes pass through some potholes or uneven roads, which will make the entire car body bumpy, so it is fixed with the car body The installed power battery will also experience the same bumps, and once the power battery becomes loose, the bumps will be upgraded to a collision. If the power source is lost, if the collision is serious, the power battery will explode, causing casualties
