Description

TECHNICAL FIELD

[0001] The utility model relates to the field of related parts of vehicle body cover plate on vehicle, specifically to a kind of impact-resistant high-strength B column cover plate assembly. BACKGROUND

[0002] The automobile covering assembly is an important and relatively independent component of the automobile body. In addition to meeting certain functions, the primary goal of its design is to meet certain stiffness and strength requirements. Insufficient stiffness of the covering can cause increased closing force, air and rain leakage, paint cracking and falling, and reduced vehicle aesthetics. Insufficient stiffness of the covering can cause vibration and noise during vehicle operation, reducing ride comfort. When the vehicle is subjected to a collision, the insufficient stiffness of the covering will cause large deformation, thereby affecting the effective survival space of the driver and passengers.

[0003] Among them, the B column cover plate assembly on the vehicle body is part of the automobile covering assembly. It is located on the side of the vehicle body. When the vehicle is subjected to a side collision, the collision energy will directly act on the B column. If the B column is insufficient in strength, the external object will directly invade the passenger compartment and pose a threat to the passengers inside the vehicle during the collision. Therefore, the impact resistance of the B column is required to be high, and the impact resistance of the B column cover plate assembly, which covers the B column, is also required to be high accordingly.

[0004] As disclosed in Chinese patent No. ZL202021628733.7: "A B column outer trim plate assembly, the B column outer trim plate assembly is an L-shaped plastic part, the B column outer trim plate assembly includes a B column outer trim plate body and a B column cover plate, the B column cover plate is connected to the B column outer trim plate body, the B column outer trim plate body is connected to the vehicle body frame, and the B column outer trim plate assembly is a single individual whole connected to the vehicle body frame. The utility model changes the sheet metal part to a plastic part, the B column outer trim plate body and the B column cover plate are assembled into the B column outer trim plate assembly, the sealing sponge, the plastic buckle and the V-shaped buckle are assembled into the B column outer trim plate assembly, and the assembly site is directly installed on the vehicle body frame through fasteners, which is simple to operate and shortens the vehicle development cycle.
