Description

Technical Field

[0001] This utility model belongs to the technical field of wheel mudguards in transportation operations, specifically relating to a front mudguard structure for a motorcycle. Background Technology

[0002] The front fender of a motorcycle is one of its important components, as shown in the instruction manual. Figure 1 As shown, the existing front fender mainly includes a main panel 1, side wings 2, a front edge 3, and a mounting bracket 4. The main panel is curved in an arc shape and the arc matches the upper part of the front wheel. The side wings are formed by extending downward from both sides of the main panel. The front edge is formed by extending slightly forward from the front end of the main panel. The mounting bracket is formed by extending downward from both sides of the main panel near the front edge. When installed on a vehicle, the mounting bracket is connected to the front fork by bolts. The main panel is above the front wheel and behind the front fork, and the front edge is in front of the front fork. The main panel, side wings, and front edge are used to block water, mud, and other debris kicked up by the front wheel from splashing backward and upward, to the sides, and forward and upward, respectively.

[0003] Since the front edge is exposed at the front of the motorcycle and obstructs the view less, it is quite important to the motorcycle's appearance. Therefore, to enhance the overall aesthetics of the motorcycle, the front edge is usually designed separately in terms of shape, pattern, and surface texture. For example, Chinese Patent CN211364794U discloses a motorcycle front fender, as shown in the attached drawings of the patent, which has a separate design for the shape of the front edge. Another example is a motorcycle and its front fender assembly disclosed in Chinese Patent CN210416834U, as shown in the attached drawings of the patent, which has a separate pattern design on the upper surface of the front edge. However, since front fenders are usually made of PP material through one-piece injection molding, and PP material has low surface energy and high chemical inertness, it is difficult to paint. It can usually only present a matte or semi-gloss texture, which is difficult to meet the need for separate design of the surface texture of the front edge. Although ABS material, which has a smooth surface and is easy to spray and electroplate, can be used to replace PP material to make front fenders so that the surface texture of the front edge can be improved through surface treatment, the cost of using ABS material to make front fenders is high. Therefore, the front fender needs to be improved to effectively control manufacturing costs while facilitating aesthetic enhancement through surface treatment and painting. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a front mudguard structure for motorcycles, which solves the technical problem that it is difficult to improve the appearance of existing front mudguards by treating the leading edge surface, and achieves the effect of facilitating appearance design and controlling costs.

[0027] Example:

[0028] Please see Figure 2 A front fender structure for a motorcycle includes an independent front fender and a decorative panel 5. The front fender includes a main panel 1, side wings 2, a front edge 3, and a mounting bracket 4. The main panel 1 is curved in an arc shape along its length. The side wings 2 are formed by extending from both sides of the main panel 1 in the width direction toward the inner side of the arc. The front edge 3 is formed by extending from one end of the main panel 1 in the length direction. The mounting bracket 4 is formed by extending from both sides of the main panel 1 in the width direction near the front edge 3 toward the inner side of the arc. The decorative panel 5 is made of ABS material (acrylonitrile-butadiene-styrene copolymer). The decorative panel 5 is located on the outer side of the arc of the main panel 1 and overlaps the front edge 3. In this embodiment, the front fender is made of PP material (polypropylene). In this embodiment, part of the decorative panel 5 covers the front edge 3 and part extends away from the front edge 3 to shorten the length of the front edge 3 and reduce the cost of the front fender. At the same time, it can cover the front end of the front edge 3 in a wider field of vision, which is beneficial to improving the aesthetics.

[0029] The motorcycle front fender structure of this utility model adds a decorative panel 5 made of ABS material, independent of the existing front fender, to the existing front fender. The decorative panel 5 is installed above the front edge 3 of the front fender, replacing the front edge 3 which is exposed in front of the motorcycle, and serves a decorative function. The decorative panel 5 is smaller than the front fender, and the use of ABS material does not significantly increase the cost. Moreover, the surface of the decorative panel 5 made of ABS material is smooth, easy to spray and electroplat, and convenient to improve the texture through surface treatment, thereby enhancing the appearance. In addition, the fact that the decorative panel 5 is independent of the front fender also facilitates processing and shaping. It can effectively solve the problem that it is difficult to improve the appearance of the existing front fender by surface treatment of the front edge 3, and achieve the effect of easy appearance design and cost control.

[0030] Please see Figure 5 and Figure 6 A connecting post 6 is formed on the side of the decorative panel 5 facing the leading edge 3. Please refer to [link / reference]. Figure 3 and Figure 4 The leading edge 3 is provided with a connecting hole 7 corresponding to the connecting post 6; the connecting post 6 passes through the connecting hole 7 and is fitted with a plum blossom-shaped spring retainer 8, the spring retainer 8 abuts against the side of the leading edge 3 away from the decorative panel 5, and the side of the leading edge 3 facing the decorative panel 5 abuts against the decorative panel 5.

[0031] The plum blossom-shaped spring retainer 8 is an existing product. It includes a fixing ring and multiple elastic claws connected to the inner side of the fixing ring and evenly distributed circumferentially. The diameter of the through hole formed between the free ends of the multiple elastic claws is smaller than the diameter of the connecting post 6. When setting the decorative panel 5, the decorative panel 5 is first placed on the outer arc of the main panel 1, and the connecting post 6 is facing the front edge 3. Then, the connecting post 6 is passed through the connecting hole 7, and the decorative panel 5 is made to abut against the front edge 3. Finally, the elastic retainer is put into the free end of the connecting post 6, so that the elastic retainer moves towards the decorative panel 5 on the connecting post 6 and finally abuts against the side of the front edge 3 away from the decorative panel 5. When the elastic retainer is put into the free end of the connecting post 6, the elastic claws of the elastic retainer are squeezed by the connecting post 6, stretched and bent and deformed in the direction away from the decorative panel 5. After being put into the retainer, the elastic claws maintain the tendency to recover under the action of elastic force. The elastic claws clamp the connecting post 6 and restrict the elastic retainer from moving in the direction away from the decorative panel 5, thereby maintaining the abutment state and realizing the installation and fixation of the decorative panel 5.

[0032] Based on the connecting post 6, it is conceivable that a threaded hole could be provided on the end face of the connecting post 6, and a screw could be used instead of the spring retainer 8 to connect to the connecting post 6 and abut against the side of the leading edge 3 away from the decorative panel 5. Alternatively, an external thread could be provided on the connecting post 6, and a nut could be used instead of the spring retainer 8 to connect to the connecting post 6 and abut against the side of the leading edge 3 away from the decorative panel 5. However, after trial use, the applicant found that, as shown in the attached... Figure 7As shown, after the front fender is installed, the gap between the front fender and the front wheel is small, making it difficult to provide operating space for using tools to tighten screws and nuts. At this time, it is difficult to install or replace the decorative panel 5. In addition, in order to achieve a reliable threaded connection, it may be necessary to add a metal part to the plastic connecting post 6 to provide threaded holes or external threads, which may increase the manufacturing difficulty and cost.

[0033] Therefore, this utility model uses a plum blossom-shaped spring clip 8 to achieve abutment and fixation based on the plastic connecting post 6. Even after the front fender is installed, the spring clip 8 can be held and inserted into the gap between the front fender and the front wheel. Then, the spring clip 8 can be pushed up and fitted onto the outside of the connecting post 6, and abut against the side of the front edge 3 away from the decorative panel 5. This helps to reduce the difficulty of installation and manufacturing cost. In practice, the circumferential surface of the connecting post 6 can be made to have a large roughness when the decorative panel 5 is formed, or several anti-slip grooves with axial spacing can be formed on the circumferential surface of the connecting post 6. This allows the elastic claw of the spring clip 8 to abut against or be inserted into the anti-slip groove, thereby improving the reliability of the spring clip 8 clamping and fixing the decorative panel 5 after installation.

[0034] Please see Figure 5 and Figure 6 The connecting column 6 is cylindrical. In this embodiment, there are three connecting columns 6, and three connecting holes 7 are provided through the front edge 3. The three connecting columns 6 pass through the three connecting holes 7 one by one. In this way, the connecting column 6 adopts a hollow cylindrical structure. With a reasonable wall thickness, its structural strength is close to that of a solid column. However, it is not only relatively lightweight, which helps to save materials, but also makes it easier to achieve uniform material flow and cooling during molding, which helps to reduce the risk of shrinkage and ensure quality.

[0035] Please see Figure 5 and Figure 6 On the side of the decorative panel 5 facing the front edge 3, a plurality of reinforcing ribs 9 are provided around the connecting column 6. The reinforcing ribs 9 are respectively connected to the root of the connecting column 6 and the decorative panel 5. In this way, by adding reinforcing ribs 9 between the root of the connecting column 6 and the decorative panel 5, the connection area between the root of the connecting column 6 and the decorative panel 5 is indirectly increased, improving the reliability of the connection between the connecting column 6 and the decorative panel 5, and the structural strength of the root of the connecting column 6 is improved, which helps to reduce the risk of cracking.

[0036] Please see Figure 3 and Figure 4 The leading edge 3 has a recessed relief groove 10 concentric with the connecting hole 7 on the side facing the decorative panel 5, and the reinforcing rib 9 is located in the relief groove 10; in this way, the relief groove 10 makes way for the reinforcing rib 9, so as to prevent the decorative panel 5 from abutting against the leading edge 3 through the reinforcing rib 9.

[0037] Please see Figure 3 and Figure 4The leading edge 3 has a protruding connecting platform on the side facing the decorative panel 5, and the connecting hole 7 is located on the connecting platform. The decorative panel 5 abuts against the platform surface. In this way, the relatively thick connecting platform serves as the mounting position for the decorative panel 5, which helps to improve the reliability of the installation of the decorative panel 5. In addition, the flat platform formed by the connecting platform abuts against the decorative panel 5 not only makes the force between the two more uniform, which helps to improve the structural reliability, but also makes it easier to control the posture of the decorative panel 5 during vehicle installation by adjusting the platform angle, which helps to reduce the design and manufacturing difficulty.

[0038] Please see Figure 3 and Figure 4 The connecting platform has a recessed center forming a weight-reducing cavity 11. The connecting platform surface around the weight-reducing cavity 11 is formed into an arched edge 12. The connecting hole 7 is located in the weight-reducing cavity 11, and the decorative panel 5 abuts against the arched edge 12. In this embodiment, the connecting hole 7 is located close to the arched edge 12. In this way, based on the connecting platform, the design of the recessed center forming a weight-reducing cavity 11 and the arched edge 12 forming a ring around the edge of the platform, which is used to abut against the decorative panel 5, not only reduces the weight while ensuring the existing function of the connecting platform, but also forms a reverse curved surface between the arched edge 12 and the weight-reducing cavity 11, which is conducive to further improving the structural strength of the installation position of the decorative panel 5 and ensuring the reliability of the installation of the decorative panel 5.

[0039] Please see Figure 3 and Figure 6 The decorative panel 5 is flat and has a flange 13 on its edge. The flange 13 is located on the side of the decorative panel 5 facing the front edge 3. In this embodiment, the area of ​​the decorative panel 5 inside the flange 13 abuts against the arched edge 12. In this way, the flange 13 on the edge of the decorative panel 5 facing the front edge 3 not only helps to improve the structural strength of the decorative panel 5, but also prevents splashed mud and sand from entering the installation gap between the decorative panel 5 and the front edge 3 during driving.

[0040] In summary, the front fender structure of the motorcycle described in this utility model adds a decorative panel 5 to cover and install above the front edge 3 of the front fender, replacing the front edge 3 which is exposed in front of the motorcycle, thus serving a decorative function. The decorative panel 5 is smaller than the front fender, and the use of ABS material does not significantly increase the cost. Moreover, the decorative panel 5 made of ABS material has a smooth surface, is easy to spray and electroplat, and can be easily improved in texture through surface treatment, thereby enhancing the appearance. For the installation and fixing of the decorative panel 5, connecting posts 6 and connecting holes 7 are respectively provided on the decorative panel 5 and the front edge 3, and a plum blossom-shaped spring retainer 8 is used to achieve abutment and fixation. Even after the front fender is installed on the vehicle, the spring retainer 8 can be held and inserted into the gap between the front fender and the front wheel to fit the spring retainer 8 onto the connecting post 6, which is convenient for installation and manufacturing and improves the practicality of the front fender structure of the motorcycle.
