Abstract

A lightweight battery box includes a tray main body frame formed by splicing a front border, back border, left border, a right border and a bottom plate, a liquid cooling pipe is laid on the upper surface of the bottom plate, the bottom plate comprises an upper bottom plate, a middle bottom plate and a lower bottom plate, the upper bottom plate and the lower bottom plate are made of carbon fiber materials, The middle bottom plate is a high-strength foam plate, the upper bottom plate, the middle bottom plate and the lower bottom plate are infiltrated by resin and solidified and bonded, and a flame retardant is added to the foam plate material, so that the lightweight battery box can ensure the liquid cooling efficiency, reduce the fire risk caused by the thermal runaway of the battery box,and meet the lightweight demand of the tray.

Description

technical field [0001] The invention relates to the technical field of battery trays, in particular to a lightweight battery tray. Background technique [0002] The tray in the existing power battery box is made of aluminum alloy or steel, without heat preservation and fire prevention measures, which cannot meet the needs of lightweight, and the liquid cooling system is greatly affected by the external environment, which reduces the liquid cooling efficiency. In addition, the battery box is thermally out of control. prone to fire. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency liquid-cooled battery box. [0004] The present invention is achieved in this way, a lightweight battery box, including a tray body frame spliced ​​by a front frame, a rear frame, a left frame, a right frame and a bottom plate, a liquid cooling tube is laid on the top of the bottom plate, and the ...
