[0027] Reference Figures 1 to 3 Some embodiments of the present invention provide an air filter for a motorcycle, comprising: a housing 100, a filter element bracket 200, and a filter element 300, wherein the filter element 300 is fixedly connected to the filter element bracket 200, the housing 100 is assembled by a left half shell 110 and a right half shell 120 by bolts, an installation cavity 101 is formed between the left half shell 110 and the right half shell 120, and the filter element bracket 200 and the filter element 300 are located in the installation cavity 101; wherein the outer periphery of the filter element bracket 200 is fixedly connected to the housing 100 and sealed, and the filter element bracket 200 divides the installation cavity 101 into a dirty cavity and a clean cavity. Clean cavity, it can be known that the air enters the dirty cavity of the air filter, and enters the clean cavity through the filter element 300, so as to filter impurities and obtain clean air; the housing 100 is provided with a mounting portion 130 located in the middle of the mounting cavity 101, and the filter element bracket 200 is provided with a soft connection component, which is connected to the mounting portion 130, and the middle part of the filter element bracket 200 has a soft support point, which reduces the vibration of the filter element bracket 200 caused by the airflow during the driving of the motorcycle, eliminates resonance, effectively reduces the vibration noise of the air filter during driving, and is beneficial to improving the service life of the filter element bracket 200.

[0028] Reference Figure 1 and Figure 3 According to some embodiments of the first aspect of the present invention, the housing 100 is provided with four mounting portions 130, and the four mounting portions 130 are arranged in a quadrilateral in the middle of the mounting cavity 101. Correspondingly, there are also four soft connection components, which correspond one to one. It can be understood that, considering the installation space of the air filter, the shape of the air filter is usually narrow and long, and the filter element bracket 200 is in the shape of a long strip, which causes the middle part of the filter element bracket 200 to be easily vibrated due to airflow. The filter element bracket 200 and the filter element 300 generate vibration noise due to airflow when the motorcycle is running. Therefore, the four mounting portions 130 and the four soft connection components are arranged in the middle, and in a quadrilateral arrangement, so that four soft support points are added to the middle part of the filter element bracket 200, thereby reducing the vibration of the filter element bracket 200 caused by airflow and improving noise.

[0029] Reference Figure 1 and Figure 3 According to some embodiments of the first aspect of the present invention, the soft connection assembly includes a fastener 210, an elastic rubber sleeve 220 is mounted on the fastener 210, the filter element bracket 200 has a mounting hole 201, the elastic rubber sleeve 220 is located in the mounting hole 201 and the outer periphery abuts the filter element bracket 200, and the elastic rubber sleeve 220 is used to realize the soft connection between the filter element bracket 200 and the housing 100, and the vibration caused by the airflow during the driving of the motorcycle is absorbed by the elastic rubber sleeve 220 to reduce noise.

[0030] Reference Figure 1 and Figure 4 According to some embodiments of the first aspect of the present invention, the mounting hole 201 is a countersunk hole, the fastener 210 is a screw, and the countersunk hole accommodates the cap head of the screw to prevent the cap head of the screw from colliding with other parts of the air filter, thereby reducing the risk of the screw falling off. Of course, the fastener 210 can also be a pin, a plastic clip, etc., which can also achieve the purpose of fixing the filter element bracket 200.

[0031] Reference Figure 1 and Figure 4 According to some embodiments of the first aspect of the present invention, a plug cap 230 is further included. The plug cap 230 is confined in the countersunk hole and covers the head of the screw. The plug cap 230 may be interference fit with the countersunk hole, or the plug cap 230 may be installed in the countersunk hole using a snap. The plug cap 230 prevents the screw from falling out and ensures that the screw and the housing 100 are firmly connected.

[0032] Reference Figure 1 and Figure 4According to some embodiments of the first aspect of the present invention, the mounting portion 130 is provided with a column head 131, and the column head 131 is inserted into the inner hole of the elastic rubber sleeve 220. It can be understood that the housing 100 is usually an injection molded part, and the mounting column 130 is a plastic column. A round hole for a matching screw is provided in the mounting column 130, and the screw is screwed into the round hole, and the column head 131 of the mounting column 130 is inserted into the inner hole of the elastic rubber sleeve 220, which improves the positioning accuracy, facilitates assembly, increases the contact area between the elastic rubber sleeve 220 and the mounting column 130, and is conducive to the elastic rubber sleeve 220 absorbing vibration and improving noise.

[0033] Reference Figure 3 and Figure 4 According to some embodiments of the first aspect of the present invention, a bushing 240 is also mounted on the fastener 210, one end of the bushing 240 is inserted into the inner hole of the elastic rubber sleeve 220, and the other end is provided with a rib 241, which abuts against the end surface of the elastic rubber sleeve 220. Considering that the elastic rubber sleeve 220 is easily deformed by force, the bushing 240 is added between the elastic rubber sleeve 220 and the fastener 210 (screw), and the bushing 240 bears the pressure of the fastener 210, preventing the elastic rubber sleeve 220 from being partially compressed and excessively deformed, ensuring the vibration absorption performance of the elastic rubber sleeve 220, and improving the service life.

[0034] Reference Figure 3 and Figure 4 According to some embodiments of the first aspect of the present invention, positioning rings 221 are provided at both ends of the elastic rubber sleeve 220, and the two positioning rings 221 cooperate to clamp the shell 100. The above structure is adopted to prevent the elastic rubber sleeve 220 from escaping from the mounting hole 201, which is beneficial to the assembly of the air filter and increases the contact area between the elastic rubber sleeve 220 and the shell 100, which is beneficial to absorb vibration and reduce noise.

[0035] According to some embodiments of the first aspect of the present invention, the elastic rubber sleeve 220 is a rubber part, which has good vibration absorption performance, low cost and is easy to shape.

[0036] Reference Figure 2 According to some embodiments of the first aspect of the present invention, a plurality of support portions 310 are provided on the periphery of the filter element 300, and the support portions 310 are fixedly connected to the housing 100 by bolts, so as to facilitate disassembly and maintenance.

[0037] Reference Figure 3 According to some embodiments of the first aspect of the present invention, an annular groove 140 is provided on the outer periphery of the shell 100, and the filter element bracket 200 is provided with an annular plate 250 which is inserted into the annular groove 140. The annular plate 250 is fixed to the shell by welding, such as high-frequency welding or ultrasonic welding. The annular plate 250 cooperates with the annular groove 140, and the positioning is accurate, which is also conducive to improving the sealing performance.

[0038] The motorcycle according to the second embodiment of the present invention includes the air filter as described above, has all the technical effects of the air filter, reduces the vibration noise of the air filter caused by airflow during driving, and brings a better experience to the driver.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
