Description

A front fender structure Technical Field

[0001] This utility model relates to the field of motorcycle technology, specifically to a front fender structure. Background Technology

[0002] The front fender is a crucial protective component in the overall structure of a motorcycle. Mounted above the front wheel, it occupies a critical position between the wheel and the main body of the motorcycle. The front fender's primary function is to prevent mud, rainwater, sand, and other debris kicked up by the front wheel during riding from directly splashing onto the motorcycle, the rider, and other critical components (such as the engine and electrical system). This effectively protects the motorcycle's appearance, riding comfort, and the normal operation and lifespan of its parts.

[0003] When motorcycles frequently travel on muddy roads, wading through water, or on unpaved surfaces, the wheels continuously throw large amounts of mud and water onto the mudguards. Existing front mudguard designs have significant shortcomings. For example, in a motorcycle front mudguard with publication number CN218258500U, the mounting slots at the mudguard mounting points allow mud to easily accumulate and fail to drain smoothly. Summary of the Invention

[0004] The present invention aims to provide a front mudguard structure to solve the problem that mud and water in the front mudguard of the prior art tend to accumulate at the installation site and are not easy to drain smoothly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A front mudguard structure includes a mudguard body, the mudguard body includes a mounting part, a rear extension plate integrally formed at the rear end of the mounting part, the free end of the rear extension plate being bent downwards, a mating part integrally formed at the front end of the mounting part, a front extension plate integrally formed at the front end of the mating part, the free end of the front extension plate being bent downwards, a clearance groove is formed in the middle of the mounting part along the front-rear direction, mounting holes are provided on both sides of the clearance groove, a front guide groove is connected to the front end of the clearance groove, the front guide groove extends through the mating part to the rear end of the front extension plate and is smoothly connected to the surface of the front extension plate, a rear guide groove is connected to the rear end of the clearance groove, and the rear guide groove is smoothly connected to the top end of the rear extension plate.

[0007] Preferably, as an improvement, a bleed groove is formed in the middle of the front extension plate along the front-to-back direction, and the bleed groove is smoothly connected to the front guide groove.

[0008] Preferably, as an improvement, mating bosses are provided on both sides of the front guide groove, and the top of the mating bosses is a flat surface.

[0009] Preferably, as an improvement, the width of the front guide groove is greater than that of the clearance groove, the rear guide groove is a fan-shaped guide groove, and the wide end of the rear guide groove is smoothly connected to the surface of the rear extension plate.

[0010] Preferably, as an improvement, the outer wall of the boss protrudes outward to form a wing, the rear end of the wing is smoothly connected to the outer wall of the mounting part, and the front end of the wing is smoothly connected to the outer wall of the front extension plate.

[0011] Preferably, as an improvement, a strip-shaped first reinforcing rib is connected between the bottom of the front guide channel and the bottom of the discharge channel along the length direction, and strip-shaped second reinforcing ribs are provided on both sides of the first reinforcing rib along the length direction, with the first and second reinforcing ribs arranged in parallel.

[0012] Preferably, as an improvement, a trapezoidal third reinforcing rib and a triangular fourth reinforcing rib are provided between the inner wall of the convex wing and the bottom of the mating boss. The third reinforcing rib is located close to the mounting part, and the distance from the free end of the third reinforcing rib to the convex wing is greater than the distance from the free end of the fourth reinforcing rib to the convex wing.

[0013] The principles and beneficial effects of this solution are as follows:

[0014] 1. The free ends of the front and rear extension plates bend downwards, which can actively catch the mud and water splashed up by the front wheel; together with the "front and rear through" mud discharge channel formed by the bypass groove, the front guide groove and the rear guide groove, the mud and water can be quickly guided to the front and rear extension plates through the front guide groove and the rear guide groove, so that the mud and water can be quickly discharged along the front and rear extension plates, effectively avoiding the accumulation of mud and water in the installation part and greatly improving the mud discharge efficiency.

[0015] 2. The front guide channel and the front extension plate, and the rear guide channel and the rear extension plate are all "smoothly connected", which can eliminate structural obstacles to the flow of mud and water, reduce fluid turbulence and impact, and further improve the speed of mud and water discharge.

[0016] 3. The curved extension plate and the through groove can guide the airflow to flow smoothly over the mudguard, reduce the separation and turbulence of air caused by the abrupt structure, and indirectly reduce the wind resistance of the motorcycle.

[0017] 4. The bleed channel in the middle of the front extension plate is smoothly connected to the front guide channel, which can further discharge the mud and water thrown up by the front wheel quickly. The smooth connection between the bleed channel and the front guide channel can reduce fluid turbulence and energy loss, making the discharge of mud and water smoother, while reducing the local wind resistance caused by structural changes.

[0018] 5. The front guide channel is equipped with mating bosses on both sides, with flat tops. On the one hand, the mating bosses can be adapted to the wiring harness lamp housing above the front mudguard. With the limiting effect of the two bosses, the installation position of the wiring harness lamp housing can be quickly aligned and positioned, simplifying the assembly process and improving installation efficiency. On the other hand, the flat top eliminates sharp structures, avoiding scratches or damage to components such as the wiring harness lamp housing caused by bumping into the sharp parts of the bosses during installation or daily maintenance. This balances functionality and safety, and optimizes the integration and adaptation performance of the mudguard.

[0019] 6. The width of the front guide channel is greater than that of the clearance channel, which can accelerate the discharge of mud and water from the clearance channel to the front guide channel; similarly, the fan-shaped rear guide channel can also accelerate the discharge of mud and water from the clearance channel to the rear guide channel, further accelerating the discharge speed of mud and water from the front extension plate and the rear extension plate.

[0020] 7. The outer wall of the boss protrudes outward to form a wing, and the two ends of the wing smoothly transition with the mounting part and the outer wall of the front extension plate, respectively. Structurally, the wing widens the lateral protection range of the mudguard, which can further prevent mud and water from splashing to the side of the vehicle body and improve the mud-blocking effect.

[0021] 8. Parallel reinforcing ribs are arranged along the length of the bottom of the front guide channel and the bottom of the discharge channel. This can significantly enhance the structural strength of the area, effectively resist the stress generated by mud and water impact and road bumps during driving, prevent deformation and cracking in the area, and ensure smooth mud discharge channel.

[0022] 9. Trapezoidal third reinforcing ribs and triangular fourth reinforcing ribs are installed on the inner wall of the convex wing and the bottom of the mating boss to specifically strengthen the structural strength of the connection area between the convex wing and the mating boss. The trapezoidal third reinforcing rib is close to the mounting part and can effectively disperse the large load generated by installation stress and mud and water impact in this area, while the triangular fourth reinforcing rib provides stable support for the weak point at the front end of the convex wing. The two work together to prevent the convex wing from deforming or breaking under stress and improve the structural strength of this part. Attached Figure Description

Detailed Implementation

[0026] The following detailed description illustrates the specific implementation method:

[0027] Example

[0028] As shown in Figure 1, a front mudguard structure includes a mudguard body, the mudguard body includes an installation part 1, a rear extension plate 2 integrally formed at the rear end (right end in the figure) of the installation part 1, the free end of the rear extension plate 2 is bent downward, a mating part 3 integrally formed at the front end of the installation part 1, a front extension plate 4 integrally formed at the front end of the mating part 3, the free end of the front extension plate 4 is bent downward.

[0029] A strip-shaped clearance groove 5 is formed in the middle of the mounting part 1 along the front-to-back direction. Two mounting holes 6 are formed on both sides of the clearance groove 5. The front end of the clearance groove 5 is smoothly connected to a front guide groove 8. The width of the front guide groove 8 is greater than that of the clearance groove 5. A bleed groove 9 is formed in the middle of the front extension plate 4 along the front-to-back direction. The front guide groove 8 passes through the mating part 3 and extends to the rear end of the front extension plate 4, where it is smoothly connected to the bleed groove 9. The rear end of the clearance groove 5 is connected to a rear guide groove 7. The rear guide groove 7 is a fan-shaped guide groove. The wide end (rear end, i.e., the right end in the figure) of the rear guide groove 7 is smoothly connected to the surface of the rear extension plate 2.

[0030] The front guide groove 8 has integrally formed mating bosses 15 on both sides, and the top of the mating bosses 15 is flat. The outer wall of the mating bosses 15 protrudes outward to form a wing 10. The rear end of the wing 10 is smoothly connected to the outer wall of the mounting part 1, and the front end of the wing 10 is smoothly connected to the outer wall of the front extension plate 4.

[0031] As shown in Figure 2, two strip-shaped first reinforcing ribs 11 are welded along the length direction between the bottom of the front guide channel 8 and the bottom of the discharge channel 9. A strip-shaped second reinforcing rib 12 is welded on each side of the first reinforcing rib 11 along the length direction. The first reinforcing ribs 11 and the second reinforcing ribs 12 are arranged in parallel.

[0032] A trapezoidal third reinforcing rib 13 and a triangular fourth reinforcing rib 14 are welded between the inner wall of the convex wing 10 and the bottom of the mating boss 15. The third reinforcing rib 13 is located close to the mounting part 1, and the distance from the free end of the third reinforcing rib 13 to the convex wing 10 is greater than the distance from the free end of the fourth reinforcing rib 14 to the convex wing 10.

[0033] In practical application, this solution achieves a secure connection with the motorcycle through the mounting holes 6 of the mounting part 1. Specifically, after aligning the front fender with the predetermined mounting position such as the motorcycle's front fork, tighten the screws in the mounting holes 6 to install the front fender of this solution onto the motorcycle's front wheel.

[0034] In practical application, when the motorcycle is in motion, the mud and water splashed up by the wheels are blocked by the downward-curving front extension plate 4 and rear extension plate 2, changing the direction of the splash and reducing the amount of mud and water splashed onto the motorcycle and rider. The mud and water splashed onto the front extension plate 4 can be quickly discharged along the front extension plate 4 under the guidance of the drainage groove 9. If mud and water splashes onto the mounting part 1, since the avoidance groove 5 connects the front guide groove 8 and the rear guide groove 7 respectively, and the width of the front guide groove 8 and the rear guide groove 7 is greater than that of the avoidance groove 5, and the front guide groove 8 and the rear guide groove 7 are smoothly connected to the avoidance groove 5, and the front guide groove 8 is also smoothly connected to the drainage groove 9, the mud and water can be quickly discharged forward and backward along the front guide groove 8 and the rear guide groove 7. The mud and water at the front end is finally quickly discharged along the drainage groove 9 of the front extension plate 4, which can effectively prevent the mud and water from accumulating at the mounting part 1 and improve the mud and water discharge efficiency.

[0035] Under high-speed driving or complex road conditions, vehicle bumps and mud and water impacts can easily cause significant stress on the mudguards. In this situation, the first reinforcing rib 11 and the second reinforcing rib 12 between the bottom of the front guide channel 8 and the bottom of the effluent channel 9, as well as the third reinforcing rib 13 and the fourth reinforcing rib 14 on the inner wall of the convex wing 10 and the bottom of the mating boss 15, play a crucial role. This multi-level reinforcing rib structure effectively disperses stress, enhances the overall rigidity of the mudguard, prevents structural damage due to stress deformation, and ensures long-term stable operation.
