The present invention relates to the technical field of battery packs for electric vehicles, in particular to a lightweight pallet for battery packs, the pallet includes a bottom plate, an external frame, blind rivet nuts, mounting beams, reinforcements and blind rivet screws, the external frame and The installation beams are all aluminum profiles, and the external frame is arranged along the outer edge of the bottom plate to form a closed-loop structure connected end to end. The top of the outer wall of the external frame is provided with an annular notch, and the rivet nut is riveted into the annular notch by the top surface of the external frame. , blind rivet nuts are used to fix the upper cover of the battery pack, the bottom plate is an aluminum plate, the installation beam is arranged on the upper surface of the bottom plate, and the two ends of the installation beam are respectively fixed on the inner side of the outer frame, and the reinforcement is arranged on The mounting beam and the external frame are fixed to form a vertical surface, and the reinforcement is made of steel sheet metal. In this solution, a steel-aluminum tray structure is formed, which not only ensures the light weight of the battery pack, but also improves the structural strength of the tray, and the tray has good sealing performance and good waterproof performance.
Description
technical field [0001] The invention relates to the technical field of battery packs for electric vehicles, in particular to a lightweight tray for battery packs. Background technique [0002] With the increasingly serious environmental pollution, clean energy has developed rapidly in all walks of life. As the main representative of clean energy vehicles, electric vehicles have developed rapidly in recent years. The power battery system is one of the important components of an electric vehicle, which refers to an energy storage device used to provide energy for the drive of an electric vehicle. It consists of one or more battery packs and a battery management (control) system. The power battery system is generally fixed under the bottom plate of the electric vehicle, and is fixed to the vehicle through a pallet. Due to the large size of the battery tray and the large load (such as ensuring the normal operation of the battery under vibration, shock and other conditions), th...
