Abstract

The invention provides a shockproof buffer device for batteries for an electric vehicle. The device is provided with an external cabinet protection structure on the basis of a conventional metal box containing a battery pack; the metal box is internally arranged into a cabinet; and the metal box is connected with the inner wall of the cabinet by a spring assembly, so that buffer protection on the battery pack is achieved through the buffer action of springs. On this basis, in order to reduce noise generated by spring expansion in the driving process while the buffer range is ensured, the spring assembly is separated through a rubber plate, so that the noise of the springs is reduced. Meanwhile, a shell filled with a phase change material is arranged in the cabinet and is in contact with the metal box containing the battery pack, so that the heat dissipation effect is improved to a certain extent by the constant-temperature characteristic of the phase change material. An advantageous technical progress is achieved through outstanding technical improvement; and the shockproof buffer device has extremely high promotion potential.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery shockproof buffer device for electric vehicles. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Pure electric vehicles, compared with fuel vehicles, the main difference (difference) lies in the four major components, drive motor, speed controller, power battery, and on-board charger. Electric vehicles use fuel cells as the power source. The chemical reaction process of the battery will not produce harmful products, so the pollution of electric vehicles is extremely small. Since the energy conversion efficiency of the battery is 2 to 3 t...
