New energy automobile battery pack frame structure

Abstract

The invention discloses a new energy automobile battery pack frame structure, and belongs to the technical field of new energy automobiles, the new energy automobile battery pack frame structure comprises a main frame and guide columns, the guide columns are parallelly assembled in the main frame, a plurality of air guide members are slidably assembled on the guide columns, each air guide member comprises a first C-shaped groove shell and a second C-shaped groove shell, and a plurality of battery bin bases slide on the guide columns and are arranged among the air guide members; the first fixing frame is assembled on the second C-shaped groove shell, one end of the first fixing frame is connected with an L-shaped plate, the second fixing frame is assembled on the first C-shaped groove shell, one end of the second fixing frame is provided with a sliding shaft, and the sliding shaft slides on the L-shaped plate and is connected with the L-shaped plate through an elastic piece. According to the battery compartment assembly, a cooling gas flow channel can be provided in a non-impact environment so as to reduce the temperature of batteries in the battery compartment assembly, and in the transverse impact process, the movement space of the battery compartment assembly can be increased through contraction of the gas guide component so as to reduce direct impact of a battery pack and improve the safety coefficient of transverse impact.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and particularly relates to a battery pack frame structure of a new energy vehicle. Background technique [0002] Now is the rising period of the development of electric vehicles, and the pace of electric vehicles replacing fuel vehicles is making great strides. At present, the classification of new energy vehicle batteries is mainly classified from two aspects, one is the battery material, and the other is the shape of the battery package. According to the battery material, it can be divided into lead-acid battery, nickel battery and lithium battery, and according to the package shape, it can be divided into cylindrical battery, square battery and soft pack battery. [0003] As a widely used new energy vehicle battery, polymer lithium ion battery will cause the lithium ion battery to short circuit and then burn under the conditions of bumping, kneading and damage. Therefore, when th...

Problems solved by technology

[0003] Polymer lithium-ion battery is widely used as a new energy vehicle battery. Because it will cause a short circuit of the lithium-ion battery and cause ignition under the conditions of bumping, kneading and damage, the battery will be damaged during the impact of the new energy vehicle. Once the compartment space is invaded by an impact object, it is very likely to cause the battery pack to be squeezed and damaged, resulting in spontaneous combustion
