Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a car trunk cover structure and a motor vehicle. Background Art

[0002] With the development of the automobile industry, the design and manufacturing of automobiles pay more and more attention to the combination of performance and aesthetics. Among them, the active rear wing, as an innovative technology, can significantly improve the aerodynamic performance of the car when driving at high speeds. The active rear wing effectively reduces the drag coefficient by changing the tail airflow, thereby improving the energy efficiency and economy of the car and increasing the cruising range.

[0003] However, the implementation of active rear wing technology also faces a series of challenges. First, its assembly structure is complex, including the motor, hinge, transmission mechanism, and internal and external decorative panels that control the lifting of the rear wing, and its weight can be as high as 10kg. If such a heavy mass is directly loaded on the trunk lid, it will cause the modal reduction of the tailgate system. The mode is the inherent vibration characteristic of the structure. The modal reduction may cause the NVH (noise, vibration and harshness) performance of the trunk lid to decline. At the same time, the modal reduction will also have an adverse effect on the durability of the trunk lid, thereby increasing the risk of durable cracking of the sheet metal and weld connection of the trunk lid.

The hinge mounting surface 132 is connected to the main plane 131, and the hinge mounting surface 132 and the main plane 131 are arranged in a step shape.
