The invention discloses a thermoplastic composite sandwich battery box tray and a manufacturing method thereof. The tray is mainly composed of a tray outer skin, a middle core material, a tray inner skin, a flange embedded part and a module mounting embedded part; the tray is composed of a sandwich structure and a reinforcing rib structure; the module mounting embedded part is embedded in an internal reinforcing rib; the flange embedded part is embedded in a flange reinforcing rib; the tray outer skin and the tray inner skin are of a laminated board structure; and the middle core material is of a light structure. According to the thermoplastic composite sandwich battery box tray, the number of parts is obviously reduced, so that the e thermoplastic composite sandwich battery box tray is simple in manufacturing process, is obviously reduced in weight, is low in cost and has a good industrial prospect compared with a metal battery tray.
Description
technical field [0001] The invention relates to composite materials and new energy sources, in particular to a thermoplastic composite material sandwich battery box tray and a manufacturing method thereof. Background technique [0002] Studies have shown that for every 100 kg weight loss of electric vehicles, the cruising range will increase by 6%-8%. The new energy battery pack is a component that accounts for a large proportion of the weight of new energy electric vehicles. Reducing the weight of the battery box can significantly reduce the weight of the vehicle and improve the battery life of the electric vehicle. [0003] At present, the bottom tray of the battery box is mainly made of steel or aluminum alloy trays. During use, there are disadvantages such as heavy box body, no insulation, and poor corrosion resistance. At the same time, there are many parts and the processing process is complicated. The sealing performance of the body has caused low production efficien...
