[0002] At present, a battery is installed on the chassis of a new energy vehicle. Above the battery is the rear seat. A seat support plate that supports the rear seat needs to be installed on the chassis under the rear seat. Currently, the seat support plate is generally formed by stamping magnesium alloy. The magnesium alloy has a small density, so the manufactured seat support plate is light in weight, which is convenient for handling and installation. The magnesium alloy has high strength and performs well in bearing the weight of the human body. Moreover, it can absorb vibrations, improve the comfort of the seat, and has good mechanical processing performance, being easy to be processed into various complex shapes to meet the requirements of different seat designs. Based on the above advantages of magnesium alloy, the relative design with the battery in the chassis part also needs to be considered. For example, considering battery heat dissipation, heat dissipation holes need to be opened on the support plate. The heat dissipation holes will damage the strength of the support plate. Therefore, several structures for installing and connecting with the vehicle chassis or frame are designed on the support plate to enhance its support strength. And considering battery maintenance, a corresponding maintenance window structure needs to be designed on the support plate. Summary of the Utility Model:
