Abstract
Description
Technical Field
[0001] This utility model relates to the field of motorcycle mudguard technology, and more specifically to an integrated mudguard. Background Technology
[0002] Motorcycles, as a flexible and convenient means of transportation, are used in a variety of scenarios. In traditional designs, motorcycles are usually equipped with side cases located on both sides of the vehicle for storing luggage, backpacks, or other personal items. This design, to some extent, meets the rider's storage needs.
[0003] Traditionally, the rear fender and chain cover of a motorcycle are two separate parts that need to be installed separately. This process is complicated and inefficient during manufacturing. Furthermore, traditional chain covers are not securely installed, and the chain can easily rub against the cover during motorcycle operation, causing abnormal noise. Therefore, improvements are needed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated mudguard that integrates the mudguard with the chain cover plate to form a mudguard body. A first mounting hole is opened on one side of the mudguard and a second mounting hole is opened on one side of the chain cover plate. The mudguard body is fixed through the first mounting hole and the second mounting hole, thereby reducing the vibration of the mudguard body and preventing abnormal noise caused by chain collision during driving.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] An integrated mudguard, comprising a mudguard body, is characterized in that: the mudguard body includes a mudguard and a chain cover plate, the mudguard and the chain cover plate are connected, the mudguard has a first mounting hole, the chain cover plate has a second mounting hole, the mudguard body is mounted on the motorcycle body through the first mounting hole and the second mounting hole, the mudguard and the chain cover plate are integrated and connected to form the mudguard body, and the first mounting hole is opened on one side of the mudguard, and the second mounting hole is opened on one side of the chain cover plate, the mudguard body is fixed through the first mounting hole and the second mounting hole, thereby reducing the vibration of the mudguard body and preventing abnormal noise caused by chain collision during operation.
[0007] Furthermore, the baffle body is also provided with an arc-shaped guide section. The mudguard and the chain cover plate are connected through the arc-shaped guide section. The design of the arc-shaped guide section provides a smooth transition between the mudguard and the chain cover plate, which enhances the overall structural strength and reduces stress concentration points.
[0008] Furthermore, the mudguard, the guide section, and the chain cover are integrally molded. The integral molding process completely eliminates the connection gaps and potential loosening points between the mudguard, the arc-shaped guide section, and the chain cover, greatly improving the overall rigidity and stability of the mudguard body, effectively suppressing vibration and deformation during driving, while simplifying the production process, reducing the number of parts and assembly steps, significantly reducing manufacturing costs and improving production efficiency and product consistency.
[0009] Furthermore, the mudguard is also equipped with a fixing groove, in which a fixing hole is opened. The fixing hole is used to fix the mudguard body. The structural design of the fixing groove provides a reinforced base for the fixing hole, increases the strength of the installation point, makes the bolt tightening more reliable, and can effectively disperse and withstand the impact force generated by vehicle bumps, preventing the installation point from tearing or deforming due to stress concentration. This ensures that the mudguard body is installed stably for a long time and avoids abnormal noise or failure due to loosening.
[0010] Furthermore, the baffle body is equipped with a mounting platform, and both the first mounting hole and the second mounting hole are opened in the mounting platform. The mounting platform provides a flatter mounting surface, simplifying the design of the corresponding mounting structure on the vehicle body.
[0011] Furthermore, the chain cover is provided with a bending plate, which is used to increase the contact area between the chain cover and the motorcycle body, thereby improving the connection rigidity.
[0012] Furthermore, the mudguard has an arc-shaped pre-reserved groove. The design of the arc-shaped pre-reserved groove provides clearance for the installation of related parts of the motorcycle body, which significantly simplifies the installation operation. An arc-shaped baffle is installed in the pre-reserved groove. The arc-shaped baffle and the arc-shaped pre-reserved groove work together to improve the rigidity of the baffle body and the overall resistance to deformation.
[0013] Furthermore, the mudguard has an arc-shaped structure, which is highly matched with the contour of the rear wheel it covers, achieving maximum coverage and optimal wrapping within a limited space, thus enhancing the overall visual harmony and aesthetics of the vehicle.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The baffle body of this utility model includes a mudguard and a chain cover plate. The mudguard and the chain cover plate are connected. The mudguard has a first mounting hole, and the chain cover plate has a second mounting hole. The baffle body is installed on the motorcycle body through the first mounting hole and the second mounting hole. The mudguard and the chain cover plate are integrated and connected to form the baffle body. The first mounting hole is opened on one side of the mudguard, and the second mounting hole is opened on one side of the chain cover plate. The baffle body is fixed through the first mounting hole and the second mounting hole, which reduces the vibration of the baffle body and avoids abnormal noise caused by chain collision during driving.
