Description

Technical Field

[0001] This utility model relates to the field of automotive wheel arch technology, and specifically discloses a carbon fiber composite automotive wheel arch. Background Technology

[0002] Wheel arches, also known as wheel covers or mudguards, are an important part of a car's exterior and functional design. Located above the wheels, their main function is to protect the vehicle body and passengers from mud, pebbles, and water splashed up by the wheels during driving, while also enhancing the vehicle's overall aesthetics.

[0003] Modern car wheel arches are typically made of various materials, including plastics, metals, and carbon fiber composites. For example, utility model patent CN220220618U discloses a car wheel arch assembly, including a wheel arch body and a mudguard. The mudguard is located on the inner side of the rear end of the wheel arch body and connected to it. The outer edge of the wheel arch body is bonded and fixed to the car body shell, and the inner edge is fixed to the car frame. Several spaced-apart mudguards are provided on the inner edge of the wheel arch body, extending along its extension direction and facing the wheel arch body. The wheel arch body has a recessed groove on one side, and each groove has a first fixing hole on its inner wall. The upper end of the mudguard has several protrusions spaced from top to bottom and extending away from the mudguard. These protrusions engage with one of the grooves located on the rear side of the wheel arch body, and each protrusion has a second fixing hole. When the internal mudguard of this invention is assembled with the rear end of the wheel arch body, the mudguard and wheel arch body can be positioned together, facilitating assembly. Currently, conventional automotive wheel arches are mostly made of plastic or metal. When installed on the car body near the wheel, the material surface is painted. However, plastic materials have low overall strength and are easily affected by ultraviolet rays, leading to aging. Metal materials are prone to rust, affecting aesthetics. Furthermore, to further enhance the function of the wheel arches when the vehicle is parked or driving at night, a vehicle warning effect can be added to the wheel arches, providing further warnings to pedestrians and vehicles from the side, thereby improving driving safety. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a carbon fiber composite material car wheel arch to solve the problem of aging or corrosion of plastic or metal wheel arches during long-term use, and to increase the warning effect of the wheel arches, so as to improve the safety of the vehicle when parked or driven at night.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber composite automotive wheel arch, including a wheel arch assembly, wherein a connecting component is provided on the back of the wheel arch assembly and a reflective component is provided on the front of the wheel arch assembly; The fender assembly includes a fender strip; The connecting component includes a mounting bracket; The reflective assembly includes a base, reflective strips, and a waterproof membrane.

[0006] Furthermore, an arched section is provided in the middle of the wheel arch strip, and strip section one and strip section two are provided at both ends of the arched section, with curved ends provided at the ends of strip section one and strip section two.

[0007] Furthermore, the wheel arch strip sequentially comprises a surface layer, an inner lining layer, a buffer layer, and a central skeleton. The central skeleton is a hollow tubular structure. The surface of the central skeleton is covered with a buffer layer, the surface of the buffer layer is wrapped with an inner lining layer, and the surface of the inner lining layer is covered with a surface layer.

[0008] Furthermore, the mounting bracket is disposed on the back of the wheel arch strip. The mounting bracket has an L-shaped structure and is evenly distributed along the first strip section, the arched section, and the second strip section of the wheel arch strip. The surface of the mounting bracket is provided with mounting holes, and the inner wall of the mounting holes is a threaded surface.

[0009] Furthermore, a gasket is provided on the inner side of the mounting bracket. The gasket has an arc-shaped structure and is made of rubber material. The gasket is bonded and fixed to the mounting bracket with resin adhesive at the connection position.

[0010] Furthermore, the base has an arc-shaped structure, and several bases are provided, which are equidistantly distributed along the front of the wheel arch strip. The base also has an arc-shaped built-in groove. The front of the base is covered with a waterproof plate, and the connection between the waterproof plate and the base is fixed by resin adhesive. The waterproof plate is made of transparent high-strength PVC material.

[0011] Furthermore, a reflective strip is provided in the built-in groove of the base. The shape of the reflective strip is fitted to the inner wall of the built-in groove. The reflective strip is composed of a base layer and a coating layer. The base layer is made of polyester material, and the coating layer is made of aluminum film material. The surface of the coating layer is also distributed with protrusions made of fluorescent material.

[0012] Furthermore, the back of the base is provided with an elastic clip, and the surface of the wheel arch strip is provided with a slot corresponding to the position of the elastic clip. The surface of the elastic clip and the inside of the slot are interlocked. The shape of the elastic clip and the shape of the slot are both regular hexagonal. The elastic clip is made of rubber material.

[0013] The working principle and beneficial effects of this solution are as follows: 1. The arched section of this solution precisely matches the wheel contour, and together with the extended strip sections on both sides, it can effectively guide the airflow around the wheel, reduce the air turbulence and eddies generated during high-speed driving, thereby reducing the drag coefficient. This design not only improves fuel economy, but also enhances high-speed driving stability. At the same time, the curved ends of the strip sections further expand the coverage area, forming a physical barrier to prevent mud, sand, stones or water splashed during driving from directly impacting the paint surface of the vehicle body, avoiding scratches and corrosion. The multi-segment structure of the wheel arch also ensures the installation is firm by increasing the distribution of fixing points, reducing the risk of loosening due to vibration, and maintaining the protection of the vehicle body for a long time. 2. The wheel arch assembly adopts a four-layer composite structure consisting of a surface layer, an inner liner layer, a buffer layer, and a central frame. This fully leverages the performance advantages of each layer of materials. The carbon fiber surface layer provides extremely high tensile strength and rigidity, the glass fiber inner liner layer enhances impact resistance and toughness, the polyester buffer layer absorbs dynamic loads, and the hollow aluminum alloy frame significantly reduces weight while ensuring support strength. The multi-layer structure disperses impact energy through elastic deformation, effectively reducing local stress concentration, preventing structural fractures, and extending service life when encountering scrapes or collisions. 3. The reflective components achieve all-weather warning function through the aluminum film reflective strips and fluorescent raised dot coating embedded in the base. The aluminum film forms a high reflectivity light band under the illumination of the vehicle headlights, while the fluorescent material emits light autonomously in the dark environment. The dual effect further improves the visibility distance to the side of the vehicle. The waterproof PVC panel adopts a fully sealed bonding process to prevent moisture and dust from entering, ensuring the long-term effectiveness of the reflective elements. It is suitable for rainy or foggy weather or nighttime parking scenarios, effectively reducing side collision accidents and improving road safety.

[0017] The following detailed description illustrates the specific implementation method: Example like Figures 1 to 6 As shown, a carbon fiber composite car wheel arch is disclosed, including a wheel arch assembly 1, a connecting assembly 2 is provided on the back of the wheel arch assembly 1, and a reflective assembly 3 is provided on the front of the wheel arch assembly 1. Flanged wheel assembly 1 includes flanged wheel strip 10; Connecting component 2 includes mounting bracket 20; The reflective assembly 3 includes a base 30, a reflective strip 31, and a waterproof membrane 32; An arched section 13 is provided in the middle of the wheel arch 10. The arched section 13 is set on the body shell above the wheel and fits the position of the wheel. The two ends of the arched section 13 are respectively provided with a strip section 11 and a strip section 2 14. The ends of the strip section 11 and the ends of the strip section 2 14 are provided with curved ends 12. The arched design and the strip section can effectively guide airflow, reduce air turbulence around the wheel, reduce wind resistance, thereby improving fuel efficiency and driving stability. The extension of the strip section can better cover the area around the wheel, prevent mud, stones and water from splashing onto other parts of the body, protect the paint surface of the body. The design of the strip section can provide more fixing points, making the installation of the wheel arch more stable and convenient. The wheel arch slat 10 sequentially comprises a surface layer 101, an inner liner 102, a buffer layer 103, and a central frame 104. The central frame 104 is a hollow tubular structure. The surface of the central frame 104 is covered by the buffer layer 103, the surface of the buffer layer 103 is wrapped with the inner liner 102, and the surface of the inner liner 102 is covered by the surface layer 101. The surface layer 101 is made of carbon fiber, the inner liner 102 is made of glass fiber, the buffer layer 103 is made of polyester, and the central frame 104 is made of aluminum alloy. Carbon fiber has extremely high tensile strength and modulus of elasticity, providing excellent mechanical properties, giving the wheel arch high strength and rigidity. Glass fiber has good... The combination of the toughness and impact resistance of the material enhances the overall toughness and impact resistance of the wheel arch. Polyester material has good elasticity and cushioning properties, which can absorb and disperse impact forces, reducing the risk of damage to the wheel arch when it is hit. Aluminum alloy has high strength and low density, which can provide good support while maintaining the lightweight of the wheel arch. The multi-layer composite structure combines the advantages of carbon fiber, glass fiber, polyester and aluminum alloy, which can optimize the comprehensive performance in terms of strength, rigidity, toughness, impact resistance, corrosion resistance and lightweight, better disperse and absorb impact forces, reduce the risk of damage to the wheel arch when it is hit, and improve the durability and service life of the wheel arch.

[0018] Mounting bracket 20 is located on the back of wheel arch 10. Mounting bracket 20 and wheel arch 10 are an integral structure, and mounting bracket 20 is also an integral structure with surface layer 101. Both are made of carbon fiber material. Through overall processing, the connection strength after installation is further improved. Mounting bracket 20 has an L-shaped structure and is evenly distributed along the strip section 11, arch section 13, and strip section 14 of wheel arch 10. The gap between mounting bracket 20 and wheel arch 10 can fit and be inserted into the position of the car body above the wheel. Mounting bracket 20 has mounting holes 21 on its surface. Through the through bolt in the mounting hole 21, it is synchronously passed through with the car body to achieve stable installation of wheel arch 10 and car body. The inner wall of mounting hole 21 is threaded and can be threaded with bolt to ensure stable fixed-point installation. A gasket 22 is provided on the inner side of the mounting bracket 20. The gasket 22 has an arc-shaped structure, which can be used to squeeze and compact the mounting bracket 20, wheel arch 10 and the car body when they are installed. The gasket 22 is made of rubber material. Through the elastic effect of rubber, the mounting bracket 20 can have a compacting and buffering effect when it comes into contact with the edge of the car body, so as to avoid the edge of the car body being squeezed and damaged. The connection between the gasket 22 and the mounting bracket 20 is fixed with resin glue, which can ensure the stability of the gasket 22 and the mounting bracket 20.

[0019] The base 30 has an arc-shaped structure. Several bases 30 are provided and are evenly distributed along the front of the wheel arch strip 10. The base 30 also has an arc-shaped built-in groove. The front of the base 30 is covered with a waterproof plate 32. The connection between the waterproof plate 32 and the base 30 is fixed by resin adhesive. The waterproof plate 32 is made of transparent high-strength PVC material. The internal condition of the built-in groove can be observed through the transparent waterproof plate 32. The waterproof plate 32 can seal the built-in groove for waterproof and dustproof protection. A reflective strip 31 is installed in the built-in groove of the base 30. The shape of the reflective strip 31 fits the inner wall of the built-in groove. The reflective strip 31 consists of a base layer and a coating. The base layer is made of polyester material and the coating is made of aluminum film material. The surface of the coating is also distributed with raised dots made of fluorescent material, which can provide nighttime warnings from the side when the vehicle is driving or parked. The aluminum film coating has a reflective effect and can provide a reflective warning when there is light. The fluorescent material can provide a nighttime warning through its fluorescent effect when walking or cycling without lighting tools. This further improves the protection effect of the wheel arches, significantly improves the visibility of the wheel arches, makes the vehicle more visible in the dark, reduces the risk of side collisions and other traffic accidents, improves driving safety, and provides a clear warning effect when the vehicle is turning, changing lanes or parking, reminding other vehicles to pay attention and avoid it, thus reducing the occurrence of traffic accidents. The base 30 has an elastic clip 33 on its back. One end of the elastic clip 33 is fixed to the base 30 by a fine screw. The surface of the wheel arch 10 has a groove 34 corresponding to the position of the elastic clip 33. The surface of the elastic clip 33 and the inside of the groove 34 are interlocked. The shape of the elastic clip 33 and the inside of the groove 34 are both regular hexagons. The elastic clip 33 is made of rubber. By interlocking the elastic clip 33 with the groove 34, the base 30 and the wheel arch 10 can be stably installed. The base 30 is made of lightweight, high-strength plastic material. Even with the addition of reflective strips 31 and waterproof plates 32, the overall weight is still relatively light. By interlocking the elastic clip 33 with the groove 34, it can be stably installed with the wheel arch 10. Since the elastic clip 33 is inserted into the groove 34, it will not deform much. Even when the vehicle is moving or bumping, the installation of the base 30 and the wheel arch 10 can be guaranteed.

[0020] In practice The core component of the wheel arch assembly 1 in this solution, the wheel arch strip 10, adopts a combination design of arched section 13 and strip section one 11 and strip section two 14. The arched section 13 fits the wheel contour, and the strip section extends to both sides of the vehicle body with curved ends 12. This structure guides the airflow above the wheel through the arched section, reducing turbulence and wind resistance. At the same time, the extended coverage of the strip section can effectively block mud or stones splashed during driving, protecting the paint. The multi-layer structure of the wheel arch strip 10 includes a carbon fiber surface layer 101, a glass fiber inner lining layer 102, a polyester buffer layer 103, and an aluminum alloy central skeleton 104. Carbon fiber provides high strength and lightweight, glass fiber enhances impact resistance, polyester layer absorbs vibration, and aluminum alloy skeleton supports the overall shape. The connecting component 2 fixes the wheel arch strip 10 to the vehicle body through the mounting bracket 20. The mounting bracket 20 is an L-shaped carbon fiber integrated structure, which is evenly distributed along the strip and arched sections of the wheel arch strip 10. Its threaded mounting holes 21 are used with bolts to complete the fastening. The contact surface between the mounting bracket 20 and the vehicle body is provided with an arc-shaped rubber gasket 22. The elasticity of the gasket generates buffer pressure when the bolt is tightened, avoiding damage to the edge of the vehicle body due to rigid contact. The gasket 22 is fixed to the mounting bracket 20 with resin glue to ensure long-term stability. The evenly distributed design of the mounting bracket 20 disperses the force on the wheel arch, while the hollow central frame 104 further reduces the weight, so that the installed wheel arch remains firm during high-speed driving or bumpy driving. The reflective assembly 3 achieves active and passive warning functions through the reflective strip 31 inside the base 30. The aluminum film coating of the reflective strip 31 reflects external light, while the fluorescent protrusions emit light in the dark. This dual effect improves the vehicle's side visibility at night or in low visibility conditions. The base 30 is made of lightweight plastic, and the built-in groove is sealed by a transparent PVC waterproof plate 32 to prevent water and dust from entering the reflective strip 31. The back of the base 30 is engaged with the hexagonal slot 34 of the wheel arch strip 10 by a rubber elastic clip 33. The deformation of the elastic clip 33 adapts to the shape of the slot, forming a gapless fixation. The modular design allows for independent replacement of a single base 30 when it is damaged, and the transparency of the waterproof plate 32 makes it easy to check the condition of the internal reflective strip 31.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
