Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of fender technology, and more specifically to an automobile fender. Background Technology
[0002] As a key component of the vehicle body, the structural design of the car fender has a significant impact on vehicle safety, aesthetics, and ease of maintenance. Traditional fenders are mostly made of steel, which increases the overall weight of the vehicle, directly leading to increased fuel consumption and carbon emissions. For example, although iron fenders have high strength, they also have high density, which is not conducive to lightweight vehicle design, especially in the trend of new energy vehicles pursuing weight reduction, where the disadvantages are even more obvious. When they are connected to components such as doors, headlights, and bumpers, dimensional deviations are prone to occur, affecting the consistency of appearance and aerodynamic performance. Steel fenders are easily corroded after long-term exposure to humid and sandy environments, and the thick sheet metal putty applied during repairs makes them prone to cracking and rusting later on. Utility Model Content
[0003] The purpose of this utility model is to provide an automobile fender. In this device, plastic or aluminum alloy material is used, combined with hollow reinforcing ribs, which reduces the weight by 30% to 40% compared with traditional steel fenders, improving fuel economy. The L-shaped structure of the reinforcing part with trapezoidal or arc-shaped ribs increases the deformation resistance by 40% to 50%, effectively disperses the impact force during collision, and protects the vehicle body to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: An automobile fender has an outer panel that is arc-shaped with the outer side being the exterior surface. The top has a raised structure that matches the front of the vehicle, the inner side is welded to or integrally formed with the top edge of the reinforcing part, and the outer side is fitted to the surface of the front component. The bottom has an arc-shaped groove that matches the wheel arch. The groove ensures the stability of the connection between the outer panel and the wheel arch during the fit, avoids gaps, and ensures the aesthetics of the vehicle. Reinforcing section: Extends inward along the edge of the outer panel, with one side welded to the inner edge of the outer panel and the other side extending inward; it is equipped with trapezoidal reinforcing ribs; the reinforcing section effectively ensures the overall quality of the fender. Fitting part: Located between the outer panel and the reinforcing part, the outer edge is welded or bolted to the inner side of the outer panel, and the inner edge is welded or bolted to the inner side of the reinforcing part; it is provided with multiple connecting holes, and is fastened to the side panel components of the vehicle body by bolts or clips; the fitting part effectively realizes the connection between the fender and the vehicle, ensuring that the fender will not fall off due to wind resistance during vehicle operation; As a further technical solution of this utility model, the front end face of the outer panel protrusion structure is fitted with the rear end face of the front bumper and connected by 2 to 4 bolts; the bottom edge of the arc-shaped groove is aligned with the top edge of the wheel arch cover; ensuring that there is no large gap between the wheel arch cover and the outer panel to prevent rainwater from seeping in; As a further technical solution of this utility model, the height of the trapezoidal reinforcing rib of the reinforcing part is 1.5 to 2 times the thickness of the reinforcing part, and the area of the hollow area accounts for 30% to 40% of the inner area of the reinforcing part; the reinforcing part, the outer plate part, and the mating part are integrally injection molded by mold; the integral molding process effectively ensures the overall quality of the fender is reliable during installation and use. As a further technical solution of this utility model, it also includes a fender liner: located inside the reinforcing part, with a buckle seat on the outer surface; bolt holes on the top edge; noise reduction holes in the liner; and the bottom edge riveted to the wheel mudguard by rivets. The noise reduction holes effectively reduce the noise generated between the vehicle and the wind resistance during driving and prevent it from entering the cab, thus effectively ensuring that the driver can concentrate during driving. As a further technical solution of this utility model, the front end of the outer panel is connected to the side of the front bumper of the vehicle by 2 to 3 bolts; the rear end is connected to the area below the A-pillar of the front side of the vehicle body by a connecting hole of the mating part; the bolts effectively ensure the stability of the connection between the outer panel and the bumper. A U-shaped groove is provided at the front end of the reinforcing section; The front end of the liner is connected to the edge of the engine compartment bottom guard plate by 2-3 clips; the rear end is connected to the bracket under the front suspension tower of the vehicle body by 2-3 bolts. As a further technical solution of this utility model, the radius of the arched arc of the outer panel is 300~500mm, the top edge is connected to the side of the rear roof beam of the vehicle body through the connecting hole of the mating part; the bottom edge is welded or bolted to the top edge of the wheel arch cover; by setting it in an arched arc, the appearance and streamline of the vehicle are effectively guaranteed. The inner side of the reinforcing part is provided with arc-shaped reinforcing ribs; the ribs are integrally injection molded with the reinforcing part, with a width of 5~8mm, extending along the arched arc, and the number of 3~5 ribs; The top of the liner is connected to the edge of the rear floor of the vehicle body by 3-4 clips; the bottom is connected to the upper edge of the rear wheel arch liner by 2-3 bolts. Compared with the prior art, the beneficial effects of this utility model are: This utility model has multiple connection points of the mating parts with the body tolerance controlled within ±0.5mm, and the gap between the outer panel and the front of the car and the wheel arch cover ≤1mm, eliminating abnormal noise and enhancing aerodynamics; it is integrally injection molded, with a surface flatness ≤0.3mm or m, and there are no dark pits or rebound defects after electrophoresis and painting, improving the overall appearance of the vehicle. In this invention, both the left and right fenders are modular and detachable, which reduces repair time by 50% to 70% and costs by 30% to 40% when there is partial damage; the fenders are no longer welded to the body and can be directly replaced when damaged, thus avoiding vehicle depreciation. This invention features a plastic outer panel and an inner lining sound-absorbing structure, which improves the cushioning performance by 50% upon impact. This invention provides injection or stamping molds with an accuracy of ±0.1mm, improving production yield by 20%~30% and is compatible with various vehicle models. Attached Figure Description
