Description

Technical Field

[0001] The utility model relates to a motorcycle fender, in particular to an assembled and greatly deformable front motorcycle fender. Background Art

[0002] At present, the front fenders of ordinary motorcycles are generally made of plastic materials, such as PP or ABS. Products made of these materials have beautiful appearance, long life, good chemical resistance, and good formability, and are widely used in the motorcycle industry. The disadvantage is that the elongation is relatively small and the mechanical strength is low. If used to produce motorcycle front fenders, their surfaces usually cannot come into contact with other parts, otherwise contact marks will appear and permanent damage will occur. Figure 1 As shown in the figure, the common front fender of a motorcycle is generally installed on the front shock absorber, and moves up and down along the axis of the front shock absorber with the front wheel. The frame, radiator, etc. need to be arranged behind the front wheel, the front fender, lower connecting plate, etc. need to be arranged above the front wheel, and the front shock absorber, etc. need to be arranged on the left and right sides of the front wheel. The longer the shock absorber stroke of the motorcycle, the better the comfort. Figure 1 , 2 As shown, when the front shock absorber travel is completely used up and the front fender moves to the top along the shock absorber axis, the movement distance (maximum travel of the front shock absorber) is S. Assuming that the distance from the tire to the lower connecting plate is L, the safety distance from the front fender to the tire is L1, the safety distance from the lower connecting plate to the fender is L2, and the wall thickness of the fender is T. It can be seen that the maximum travel of the front shock absorber S = L-L1-L2-T, and this travel is strictly limited. Summary of the invention

[0003] In order to solve the above technical problems, the utility model designs a motorcycle fender.

[0004] Technical Solution

[0005] The technical solution of the utility model is as follows: a motorcycle mudguard, comprising a front mudguard rear part (11), a front mudguard soft rubber (12), and a front mudguard front part (13). The front mudguard soft rubber (12) is provided with an undercut structure (121), and the undercut structure (121) is divided into three sections, wherein the lower section (1211) is a short cylindrical section, and has a matching relationship with the mounting hole (111) of the front mudguard rear part (11). After installation, the gap is very small, so that the front mudguard soft rubber (12) does not move relative to the front mudguard rear part (11); the middle section (1212) is an umbrella-shaped section, and its outer diameter is larger than the inner diameter of the mounting hole (111) of the front mudguard rear part (11). After installation, it will not fall out, and the installation is stable; the upper section (1213) is a long cylindrical section, which is convenient to pull with fingers or tools, so that the umbrella-shaped middle section (1212) passes through the mounting hole (111) of the front mudguard rear part (11). The undercut structure (121) is installed on the installation hole (111) of the front mud plate rear part (11) by means of assembly, and the front mud plate rear part (11) has a hollow area (112) to accommodate the front mud plate soft rubber (12) to deform downward. The front mud plate front part (13) is installed on the front mud plate rear part (11) by means of buckles and bolts.

[0006] Preferably, the front mud plate soft rubber is installed on the rear part of the front mud plate by assembly.

[0007] Preferably, the front mud plate soft rubber is made of soft elastic material.

[0008] Preferably, the front part of the front fender and the rear part of the front fender can be combined into one component and do not need to exist independently.

[0009] Preferably, the front mud panel soft rubber is made of soft elastic material, which can directly contact with other parts of the vehicle body without producing contact marks.

[0010] Preferably, the safety distance L2 from the lower link plate to the fender can be zero, and the safety distance L1 from the front fender to the tire can be reduced.

[0011] Preferably, the material of the front mud plate soft rubber is mainly EPDM rubber or silicone rubber, which has the main characteristics of high elongation and good weather resistance. When used in this patent, it is easy to assemble, has a long service life and low cost.

[0012] Beneficial effects:

[0013] By using the motorcycle mudguard designed by the utility model, the use stroke of the front shock absorber can be greatly increased, the riding comfort is enhanced, and the appearance is beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0026] Referring to the accompanying drawings, a motorcycle mudguard comprises a front mudguard rear part (11), a front mudguard soft rubber (12), and a front mudguard front part (13). The front mudguard soft rubber (12) is installed on the front mudguard rear part (11) by means of an assembly method through a series of inverted buckle structures (111), and is characterized in that: the inverted buckle structure (121) is divided into three sections, the lower section (1211) is a short cylindrical shape, which has a matching relationship with the mounting hole (111) on the front mudguard rear part, so that the front mudguard soft rubber does not move relative to the front mudguard rear part; the middle section (1212) is conical, and its outer diameter is larger than the inner diameter of the mounting hole (111) at the front mudguard rear part, so that it will not fall out after installation, ensuring a stable installation; the upper section (1213) is a long cylindrical shape, which is convenient to pull with fingers or tools, so that the umbrella-shaped middle section (1212) passes through the mounting hole (111) at the front mudguard rear part.

[0027] Working principle: The front mud plate soft rubber is a soft elastic material, such as Figure 4 As shown, when the front fender assembly moves to the top with the front wheel, the safety distance L2 from the lower connecting plate (4) to the fender can be zero, the lower connecting plate (4) directly contacts the front fender soft rubber (12), and the safety distance L1 from the front fender to the tire can be reduced. Taking this vehicle model as an example, the maximum stroke of the shock absorber is only 128mm when the front fender of the ordinary structure is adopted. If the front fender of the novel design is adopted, the maximum stroke of the shock absorber can reach 150mm, and the maximum stroke of the shock absorber increases by 17%, and the comfort of the whole vehicle can be greatly improved.

[0028] The above is only a preferred embodiment of the utility model, and does not impose any formal limitation on the structure of the invention. Any simple modification and equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model still belong to the technical essence of the utility model.

[0029] the scope of the technical programme.
