The invention relates to the technical field of new energy vehicles, and discloses a battery protection device for new energy vehicles, which includes a vehicle frame, tires are fixedly fitted on both sides of the front of the vehicle frame, and tires on one side of the vehicle frame are fixedly installed on the back of the tires. The shock-absorbing master cylinder is fixed with a shock-absorbing wheel cylinder inside the shock-absorbing master cylinder, and the bottom of one side of the inner chamber of the shock-absorbing wheel cylinder is provided with a flow hole and communicated with the inside of the shock-absorbing master cylinder. There is a piston in the top movable sleeve, and the top of the piston is fixedly connected with one end of the damping spring. The protection device for battery packs of new energy vehicles can realize the , The protective effect on the battery pack installation box, avoiding the damage to the battery pack inside the battery pack installation box due to protrusions, and enhancing the off-road capability of the car.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a protective device for battery packs of new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Vehicles with new technology and new structure can be divided into pure electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles. [0003] The most important part of new energy vehicles is the battery pack, but the current new energy vehicles install the battery pack at the rear of the car, which is not conducive to balancing the front and rear weight of the car. Some new energy vehicles install the battery pack at the bottom of th...
