Problems solved by technology

[0002] Most of the current new energy electric vehicles use batteries as the power source, and pack a battery pack by connecting multiple batteries to each other. However, there are some shortcomings in the vibration reduction and heat dissipation of electric vehicle battery packs today: the car will Make the battery pack vibrate to different degrees, which is easy to damage the battery; the battery will generate a lot of heat during operation, and the heat cannot be dissipated in time, which will seriously affect the performance of the battery pack and shorten the service life of the battery
[0004] In order to solve the common problems in the field that there is sloshing in the battery cavity, a single vibration damping device, the battery pack is not waterproof and the heat dissipation effect is not good, etc., the present invention is made

Abstract

The invention provides a vibration reduction and heat dissipation system for a vehicle-mounted battery pack, comprising a battery pack, a storage device, a vibration reduction device, a fixing device and a heat dissipation device, the battery pack is arranged in the storage device, and the vibration reduction The device, the fixing device, and the heat dissipation device are respectively arranged on the storage device, and the storage device includes several storage blocks, each of which is connected end to end to form a storage groove, and the vibration damping device is arranged on The outer periphery of the storage tank, the heat dissipation device is arranged on the inner wall of the storage tank and fixedly connected with the inner wall of the storage tank. Vibration damping components are installed in both vertical and horizontal directions, and are set separately to ensure that the vibration of the battery box in all directions can be attenuated. At the same time, the replacement of individual components reduces the replacement cost of the entire set of vibration damping components. Improved work efficiency.

Description

technical field [0001] The invention relates to the technical field of automotive power batteries, in particular to a vibration reduction and heat dissipation system for a vehicle battery pack. Background technique [0002] Most of the current new energy electric vehicles use batteries as the power source, and a battery pack is packaged by connecting multiple batteries to each other. However, there are some deficiencies in the vibration reduction and heat dissipation of the battery pack of electric vehicles today: the car will The battery pack will vibrate to different degrees, which will easily damage the battery; the battery will generate a lot of heat during the working process, and the heat can not be dissipated in time, which will seriously affect the performance of the battery pack and shorten the service life of the battery. [0003] For example, the prior art of US09045033B2 discloses a vibration damping control device. When the lateral reaction force of each wheel c...
