Sheet type buffer device for new energy automobile battery

Abstract

The invention discloses a sheet type buffer device for a new energy automobile battery, and the device comprises two base plates arranged in parallel, wherein a plurality of buffer bodies are arrangedbetween the two base plates; the buffer body comprises a first elastic body and a second elastic body which are folded together, wherein the first elastic body and the second elastic body are arc-shaped plates; at least one part of every two adjacent buffer bodies is overlapped to form an overlapped space, and two enclosed spaces are formed between every two adjacent buffer bodies and the two base plates. A sheet type structure is adopted, and a buffer effect different from that of a conventional spring structure is formed, so the overall buffer effect is better, the thickness of the buffer device can be reduced to a certain extent, the occupied space of the buffer device is reduced, and the utilization rate of battery pack space is increased; in addition, the buffer structure can form aheat dissipation structure while realizing buffer, and an overlapping space, an enclosing space and the like formed in the buffer structure can play a role of an air duct, so the heat dissipation effect of the battery is improved.

Description

technical field [0001] The invention relates to the technical field of battery buffer devices, in particular to a sheet-type buffer device for new energy vehicle batteries. Background technique [0002] The power of new energy vehicles comes from the battery pack. At present, a big problem facing new energy vehicles is the battery life of the vehicle. Theoretically speaking, the larger the battery capacity, the greater the battery life of the vehicle, but it cannot be singled out in the process of vehicle manufacturing. To consider the issue of battery capacity, as well as factors such as cost, load, and space, the current solution is to increase the capacity of the battery in a limited space, so the space utilization rate of the battery in the vehicle should be as high as possible. [0003] Due to the complex driving conditions of the car, the buffering of the battery pack inside must be considered. The addition of the buffer structure will inevitably occupy a certain amoun...

[0002] The power of new energy vehicles comes from the battery pack. At present, a big problem facing new energy vehicles is the battery life of the vehicle. Theoretically speaking, the larger the battery capacity, the greater the battery life of the vehicle, but in the process of vehicle manufacturing, it cannot be single To consider the issue of battery capacity, as well as factors such as cost, load, and space, the current solution is to increase the capacity of the battery in a limited space, so the space utilization rate of the battery in the vehicle should be as high as possible

[0003] Due to the complex driving conditions of the car, the buffering of the battery pack inside must be considered. The addition of the buffer structure will inevitably occupy a certain amount of space. The traditional spring-type buffer structure is no longer suitable for the buffering of the battery pack. , a better buffer structure is needed;

[0004] In addition, the heat dissipation of the battery pack must also be considered. The existing buffer structures often only play a buffer role. In the initial design, the buffer device and heat dissipation are rarely considered together. Therefore, the common buffer structure and heat dissipation device of the battery pack Basically, it is to separate two parts that are not related
