[0002] The subframe is a crucial component of the vehicle chassis, connecting the suspension system to the vehicle body through the subframe. Conventional rear subframes are typically connected to the vehicle body through four mounting points. With the rapid development of new energy vehicles both domestically and internationally, rear-mounted electric motors or dual-motor configurations are becoming increasingly common, requiring the integration of multiple ports such as rear electric drive suspension, fenders, low-voltage wiring harnesses, and high-voltage wiring harnesses. This places greater demands on the performance of the rear subframe. Existing technologies connect the body and frame using a single-layer sheet metal stamping structure. However, this existing frame connection structure suffers from weak overall rigidity, resulting in stiffness and strength deficiencies under harsh operating conditions. This also has limitations in improving NVH and driving performance. Summary of the Invention
