Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, and in particular relates to a vehicle body rear tailgate frame reinforcement structure and a vehicle. Background Art

[0002] The body-in-white of a car is an important carrier of the car. The quality of the body-in-white structure will directly affect the performance of the car product. The overall torsion of the body-in-white is an important performance indicator for evaluating the body-in-white, which directly determines the performance and quality of the car product. The overall torsional stiffness is affected by the stiffness of the rear structure, so improving the torsional stiffness of the rear body-in-white can improve the torsional stiffness of the entire vehicle. The structure of the rear tailgate door frame, as one of the key rear structures, directly affects the rear torsional stiffness. Therefore, strengthening the stiffness of the rear tailgate door frame structure can improve the stability of the entire rear structure and improve the overall torsional stiffness of the body-in-white.

[0003] At present, the rear door frames of cars are mostly not annular cavity structures. Therefore, the stability of the rear door frame structure of cars is worse than that of SUV models, and the door frame has a weaker ability to resist deformation. The vehicle body will be partially deformed during driving, rubbing and colliding with surrounding parts, thus producing abnormal noise. In addition, the torsional stiffness of the rear door frame will also affect the torsional stiffness of the entire vehicle body. Insufficient torsional stiffness leads to low torsional modes, which are easily coupled with external excitation frequencies to produce resonance, thereby affecting NVH performance. In addition, the stiffness of the rear door frame also directly affects the modes of the coat rack and the back door. Insufficient stiffness leads to low modes, which also affects NVH performance.

[0004] It is desirable to provide an improved vehicle body rear tailgate frame reinforcement structure, particularly with regard to how to enhance the stiffness of the tailgate frame joint and the stability of the overall structure of the rear tailgate frame. Summary of the invention
