Description

Technical Field

[0001] The utility model relates to the technical field of automobile side wing panels, in particular to an impact-resistant automobile side wing panel. Background Art

[0002] A car's side fenders (often called "side door panels" or "wings") are part of the car's body, located on the side of the car, connecting the front and rear sections. The main function and feature of a side fender is that it is an important component of a car's exterior design. The fenders of different car models vary in design style, enhancing the vehicle's overall visual impact and making it appear more stylish and dynamic. For example, the fenders of some sports cars have smooth lines that echo the overall shape of the car body, enhancing the vehicle's appearance. When the car is traveling at high speeds, the fenders can guide airflow more smoothly through the sides of the car body, reducing air resistance and thus improving the vehicle's fuel economy and driving stability. For example, the fenders of some high-performance sports cars are very sophisticated in design, which can effectively reduce the drag coefficient, making the vehicle more stable at high speeds and reducing unnecessary air vortices and turbulence.

[0003] In the existing technology, when a car is parking or driving, it may encounter collisions with other vehicles or objects, which may cause damage to the car body. In addition, the vehicle may face various external impacts during use, such as uneven road surface, flying stones, etc., which may cause damage to the car side fenders, which may require repair or replacement, increasing the cost of use. Utility Model Content

[0011] Preferably, the decorative coating has a thickness of 0.05 mm to 0.2 mm.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In this utility model, the reinforcement layer utilizes hot-formed or cold-formed high-strength steel, providing enhanced safety and impact resistance while maintaining a low weight. The impact-resistant layer is made of polyurethane foam, which has excellent energy absorption properties, effectively mitigating the impact of collisions and providing a certain degree of sound insulation. This improves the fender's impact absorption capacity and structural strength, reducing the probability of damage to the fender, thereby reducing the need for repairs and replacements, and ultimately lowering vehicle costs.

[0014] 2. In the present invention, the sound insulation layer material is lead plate. Lead has a high density and can effectively block low-frequency sounds to reduce road noise and improve ride comfort.
