Description
Technical Field
[0001] This utility model relates to an electric vehicle component, specifically a novel electric vehicle rear mudguard. Background Technology
[0002] Currently, electric vehicle rear mudguards are typically injection-molded plastic parts installed on the upper side of the rear wheel. This type of mudguard includes a mudguard body and a support plate. The lower end of the support plate is mounted on the rear swingarm, and the mudguard body is fixed to the support plate. Usually, the support plate has circular mounting holes for the mudguard, and the mudguard body has corresponding circular mounting holes. These circular mounting holes and mounting holes are typically arranged in at least two pairs. This structure allows for a single-fit connection between the electric vehicle rear mudguard and the rear wheel and swingarm, suitable for stationary vehicles. While electric vehicles typically use rear wheels of varying diameters and corresponding swingarms to accommodate different road surfaces and power outputs, current mudguards are designed for single-size rear wheels. When a different rear wheel or swingarm is installed, the existing mudguard becomes unusable, requiring a new one. This necessitates creating new molds and support frames for the mudguard body and support frame to accommodate different rear wheel diameters. Since electric vehicle rear mudguards are generally not considered safety components, it's unnecessary to have a new mudguard for every different rear wheel diameter, thus increasing the overall cost of the vehicle. Summary of the Invention
[0003] This utility model provides a specific structure for a new type of electric vehicle rear mudguard, which is suitable for use with different wheel diameters, and reduces the overall vehicle cost while ensuring the function of the rear mudguard.
[0004] To achieve the above-mentioned technical effects, this utility model provides a novel rear mudguard for electric vehicles, comprising a mudguard body and a support plate. The mudguard body includes an integrally formed mudguard side plate and a mudguard top plate, and a horizontal fork support is provided at the rear of the electric vehicle's horizontal fork. The support plate includes a transverse support plate and a longitudinal support plate. The lower end of the longitudinal support plate is fixedly connected to the rear of the transverse support plate, and at least two circular mudguard mounting holes are provided on the middle section of the longitudinal support plate. The middle section of the mudguard side plate is provided with a longitudinal strip-shaped mudguard mounting hole that matches the circular mudguard mounting hole. The mudguard body is fixed to the circular mudguard mounting hole by screws passing through the longitudinal strip-shaped mudguard mounting hole. The front section of the horizontal fork support is provided with an arc-shaped horizontal fork front hole, and the rear section is provided with a horizontal fork rear hole. The front section of the transverse support plate is provided with a side plate transverse circular hole that matches the arc-shaped horizontal fork front hole, and the rear section is provided with a side plate transverse circular hole that matches the horizontal fork rear hole.
[0005] The novel electric vehicle rear mudguard using the above technical solution is adaptable to rear wheels of different diameters because its height is adjustable and fixed to a longitudinal support plate. Furthermore, the support plate's movable position and adjustable angle are fixed to the swingarm bracket, ensuring that the longitudinal axis of the support plate coincides with the rear wheel radius. This design provides the electric vehicle rear mudguard with strong versatility, suitable for different wheel diameter models. This avoids the drawbacks of needing to create new molds and replace the support plate when changing rear wheels of different diameters. Since the rear swingarm is related to safety when changing rear wheels of different diameters, it generally needs to be replaced and redesigned simultaneously. However, the rear mudguard is usually not a safety component, so it is unnecessary to have a new rear mudguard for every different rear wheel diameter, thus reducing the overall cost of the vehicle.
[0006] Furthermore, the longitudinal axial line of the longitudinal support plate coincides with the radius line of the rear wheel. This ensures that the rear fender and the outer rim of the rear wheel maintain an appropriate and equidistant gap, thus better accommodating rear wheels of different diameters.
[0007] Furthermore, the bracket plate is made of metal. Using a metal bracket plate makes it easier to drill holes and weld nuts for installation, and it is more convenient to connect with bolts and nuts, while ensuring the strength of the backplate made of injection molded parts.
[0008] The mudguard side plate is further defined to have a decorative groove, and the longitudinal strip-shaped mounting hole of the mudguard is located within the decorative groove. A decorative cover is also provided, which matches and snaps into the decorative groove. By placing the longitudinal strip-shaped mounting hole of the mudguard within the decorative groove and using the decorative cover to snap it into the groove, both aesthetics and the overall airtightness of the mudguard are ensured, preventing mud from being thrown out from the longitudinal strip-shaped mounting hole of the mudguard.
[0009] In addition, the electric vehicle is relatively compact, with the rear reflector, rear license plate light and rear license plate integrated into the body of the rear fender, thus improving driving safety.
[0010] The new electric vehicle rear mudguard using the above technical solution can reduce the overall cost of the vehicle, ensure driving safety and aesthetics, and overcome the shortcomings of the existing electric vehicle rear mudguards which are used only for one purpose.
