Description

Technical Field

[0001] This invention relates to a decorative cover for a motorcycle air filter. Background Technology

[0002] Motorcycle air filter covers on the market are usually integrated with the air filter itself, generally made of modified polypropylene (PP+T30), and come in a single color, usually black, with a textured surface. Secondly, to optimize the air filter's appearance, the entire housing usually needs to be replaced. Since the air filter functions as part of the motorcycle's air intake system, combining functionality, sealing, and aesthetics, the housing structure is often tightly packed and complex. Being a plastic component, the injection molding cost and surface finish requirements are both high. Alternatively, to optimize the air filter's appearance, one approach is to modify the air filter itself. However, this involves a long design cycle, limited adaptability, and poor versatility. A newly designed air filter housing needs to ensure airtightness and reliable installation with the inner housing, requiring higher precision in the injection molding process. Furthermore, using ordinary modified polypropylene (PP+T30) can result in poor wear resistance. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a motorcycle air filter decorative cover that is simple to install, reduces mold complexity, provides a more secure and reliable connection, and improves versatility.

[0004] Technical solution: The motorcycle air filter decorative cover of the present invention includes a decorative cover and an air filter. The decorative cover is fixed to the side surface of the air filter by threaded connection and snap-fit ​​connection.

[0005] The air filter consists of an outer shell and an inner shell, which are connected by mounting screws.

[0006] The decorative cover is provided with mounting posts 1a, 1b, 1c, and 1d evenly distributed around the perimeter. The air filter housing is provided with mounting holes 2a, 2b, 2c, and 2d corresponding to the positions of the mounting posts. Each of the four mounting posts is provided with a circular boss to reduce the contact area between the injection molded parts and ensure reliable installation between the two parts.

[0007] The mounting posts of the decorative cover are connected to the mounting holes of the air filter housing by self-tapping screws.

[0008] A bushing is provided between the air filter housing and the self-tapping screws.

[0009] The decorative cover is integrally molded using injection molding, and the material is an elastomer-based plastic. This facilitates installation and improves comfort, allowing the occupant's lower legs to better conform to the air filter while reducing friction. It is elongated in shape, with a contact area of ​​1 / 3 to 1 / 4 of the air filter housing. The upper and lower edges follow the same curve as the air filter housing. There is a triangular perforated structure at both the top and bottom; the upper triangle is perforated to avoid the installation point. The triangular design reduces the weight of the component while ensuring proper installation. The elastomer-based plastic material is thermoplastic vulcanized rubber.

[0010] The outer surface of the air filter housing is provided with a limiting groove, and the corresponding position of the decorative cover is provided with a full circle of limiting blocks. The limiting groove and the limiting blocks form a snap-fit ​​connection to further strengthen the connection.

[0011] The surface treatment process of the motorcycle air filter decorative cover adopts a leather texture treatment. By adding a leather texture effect to the injection mold, the product is directly processed into an air filter decorative cover through injection molding without any other surface treatment.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: (1) The motorcycle air filter decorative cover of the present invention realizes the integrity of the motorcycle air filter and the decorative cover. The injection-molded decorative cover can realize the complex appearance parts and achieve the coordination of the coverage area under the condition of stable connection, overcoming heat dissipation and air intake interference; (2) Its assembly is simple and easy to operate. The threaded connection and the snap-fit ​​connection are not exposed, ensuring the appearance is beautiful and the installation is tight, and no resonance or abnormal noise will be generated.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figures 1-6 As shown, the motorcycle air filter decorative cover of the present invention includes a decorative cover 1 and an air filter 2. The decorative cover 1 is fixed to the side surface of the air filter 2 by threaded connection and snap-fit ​​connection.

[0023] The air filter 2 includes an air filter housing 21 and an air filter inner housing 22, which are connected by mounting screws. The decorative cover 1 is provided with mounting posts 1a, 1b, 1c, and 1d evenly distributed around its perimeter. Each of the four mounting posts has a circular boss with a height of 1.4 mm and an outer diameter of 9 mm. The air filter housing 21 is provided with mounting holes 2a, 2b, 2c, and 2d corresponding to the positions of the mounting posts. The mounting posts of the decorative cover 1 are connected to the mounting holes of the air filter housing 21 by self-tapping screws 3. Two bushings 4 are located between the self-tapping screws 3 and the air filter housing 21. Due to the special nature of the curved surface, two bushings are added to prevent the mounting screws from penetrating the parts due to insufficient depth. The mounting holes of the air filter housing 21 are completed by drilling.

[0024] Decorative cover 1 is integrally molded using injection molding. It is made of plastic material with an elastomer and is long and narrow. Its contact area is 1 / 4 of the air filter housing. The upper and lower edges have the same curve trend as the upper and lower edges of the air filter housing. There is a triangular hollow structure at the top and bottom, with the upper triangle having a hollow structure to avoid the installation point. The plastic material with an elastomer is thermoplastic vulcanized rubber.

[0025] like Figure 4 and Figure 5 As shown, a limiting groove is provided on the outer surface of the air filter housing 21, and a full circle of limiting blocks is provided on the inner side of the decorative cover 1. The surface treatment process of the decorative cover 1 adopts a leather texture treatment. By adding a leather texture effect on the injection mold, it is directly processed into an air filter decorative cover through the injection molding process.

[0026] Therefore, this invention is a standalone air filter decorative cover design, using injection molding technology. The material is paintable acrylonitrile-butadiene-styrene (ABS) or nylon (PA), etc. The structure adopts a mounting post and mounting hole design, evenly distributed around the perimeter, combined with snap-fit ​​connections to further increase stability. The mounting holes on the air filter body can be supplemented by additional processing. The connection between the two is fastened with self-tapping screws. The air filter decorative cover can be painted in multiple colors to distinguish it from the air filter body. In addition, the screws are reliable and easy to install and remove.

[0027] By optimizing the appearance of the air filter, the visual appeal of the air filter is enhanced, reducing mold development costs and shortening the development cycle without altering its functionality. Meanwhile, the decorative panel is easily installed by connecting to the air filter body, reducing mold complexity and ensuring a reliable and secure connection. Furthermore, the addition of an air filter decorative cover allows the same air filter to be fitted with different styles of decorative covers, improving versatility and adapting to the appearance requirements of various motorcycle models.
