[0021] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2As shown, this application provides a motorcycle 100, which includes a frame 11, a body panel 12, a suspension system 13, an engine 14, an air filter 15, a seat 16, and a running gear 17. The frame 11 forms the basic framework of the motorcycle 100. The body panel 12 includes side guards 121, which are connected to the frame 11. Viewed from the width direction of the motorcycle 100, the side guards 121 cover at least a portion of the frame 11. The side guards 121 are located below the seat 16 and distributed on the left and right sides of the seat 16, with the upper edge of the side guards 121 contacting the seat 16. The suspension system 13 is connected to the frame 11 and includes a shock absorber and a rear suspension assembly (not shown). The engine 14 is connected to the frame 11 through the rear suspension assembly, allowing the engine 14 to rotate relative to the frame 11. The two ends of the shock absorber are connected to the frame 11 and the engine 14, respectively. At least a portion of the running gear 17 is located below the frame 11 and is drive-connected to the engine 14. An air filter 15 is connected to the engine 14 and is used to filter incoming air to remove impurities and deliver the filtered air to the engine 14.

[0023] For ease of description, the following are also defined: Figure 1 The motorcycle 100 is shown in the front-back, left-right, and up-down directions. In the description of this application, the height direction of the motorcycle 100 refers to... Figure 1 The vertical direction shown refers to the width direction of the motorcycle 100. Figure 1 The left and right directions are shown.

[0024] like Figure 2 and Figure 3 As shown, in one implementation, the air filter 15 includes a first housing 151, a second housing 152, and a filter assembly 153. The first housing 151 is connected to the vehicle frame 11. The filter assembly 153 is installed in the first housing 151 and cooperates with the first housing 151 to form a first filter chamber 101. The second housing 152 is detachably installed in the first housing 151 and cooperates with the filter assembly 153 to form a second filter chamber 102. The filter assembly 153 includes a filter element support 1531 and a filter element 1532. The filter element support 1531 is fixed to the first housing 151, and the filter element 1532 is detachably installed in the filter element support 1531. The filter element 1532 is used to filter impurities (such as dust, sand particles, etc.) in the air.

[0025] Furthermore, the first housing 151 and the second housing 152 are distributed along the width direction of the motorcycle 100. The air filter 15 includes a plurality of fasteners 154, which pass through the second housing 152, the filter assembly 153 and the first housing 151 along the width direction of the motorcycle 100 to fix the second housing 152, the filter assembly 153 and the first housing 151.

[0026] Specifically, the air filter 15 also includes an exhaust pipe 155, an exhaust port 1511, and a grille 1521. The exhaust port 1511 is a through hole formed on the first housing 151, connecting the first filter chamber 101 to the outside. One end of the exhaust pipe 155 is connected to the exhaust port 1511, and the other end of the exhaust pipe 155 is connected to the intake passage (not shown) of the engine 14. The grille 1521 is disposed on the second housing 152, connecting the second filter chamber 102 to the outside. Air can enter the second filter chamber 102 through the grille 1521. The air in the second filter chamber 102 enters the first filter chamber 101 through the filter element 1532, and enters the intake passage of the engine 14 through the exhaust port 1511 and the exhaust pipe 155.

[0027] If filter element 1532 needs to be replaced, the second housing 152 is removed from the first housing 151, then the filter element 1532 is removed from the filter element holder 1531 and a new filter element 1532 is installed. With this design, the filter element holder 1531 does not need to be replaced during filter element 1532 replacement, improving the convenience of filter element 1532 replacement and reducing the cost of filter element 1532 replacement.

[0028] like Figure 3 As shown, specifically, when viewed along the height direction of the motorcycle 100, the first housing 151 overlaps with the side guard plate 121, and at least part of the second housing 152 does not overlap with the side guard plate 121, so that at least part of the second housing 152 is exposed outside the side guard plate 121, avoiding interference from the side guard plate 121 when disassembling or assembling the second housing 152.

[0029] In one implementation, the outer edge of the filter element 1532 is provided with several fixing portions 1532a, and the filter element support 1531 has several mating portions 1531a corresponding to the fixing portions 1532a. The mating portions 1531a are located on the side of the filter element support 1531 facing the second housing 152. The filter element 1532 can be installed on the filter element support 1531 by the mating portions 1531a cooperating with the fixing portions 1532a.

[0030] In this embodiment, the mating part 1531a is provided with a connecting hole, and the fixing part 1532a has a through hole that extends through itself along the width direction of the motorcycle 100. By passing a fastening bolt through the through hole and the connecting hole in sequence, the filter element 1532 can be detachably installed on the filter element bracket 1531.

[0031] Optionally, the mating part 1531a is provided with a groove, and the fixing part 1532a is provided with a buckle. The filter element 1532 is detachably installed on the filter element bracket 1531 by the engagement of the buckle and the groove.

[0032] like Figure 3 and Figure 4As shown, in one implementation, the second housing 152 includes a front air cover 1522 and a rear air cover 1523. The front air cover 1522 is fixedly connected to the first housing 151, and a grille 1521 is provided at the front of the front air cover 1522. The rear air cover 1523 is detachably connected to the first housing 151. In this embodiment, the second filter chamber 102 is divided into a front air chamber 1021 and a rear air chamber 1022. The front air chamber 1021 is formed by the front air cover 1522 covering at least a portion of the filter assembly 153, and the front air chamber 1021 communicates with the outside through the grille 1521. The rear air chamber 1022 is formed by the rear air cover 1523 covering at least a portion of the filter assembly 153. A partition 156 is provided between the front air chamber 1021 and the rear air chamber 1022. The front air chamber 1021 and the rear air chamber 1022 are connected by an air pipe 158 that passes through the partition 156, so that the flow direction of air entering the rear air chamber 1022 is consistent with the extension direction of the air pipe 158, thereby increasing the air velocity in the rear air chamber 1022.

[0033] like Figure 5 As shown, in one implementation, the side guard 121 has an air intake 1211 extending through itself along the width direction of the motorcycle 100. Viewed from the width direction of the motorcycle 100, the air intake 1211 overlaps with at least a portion of the air intake grille 1521. It should be noted that during the motorcycle 100's operation, air enters the air filter 15 through the air intake 1211 and grille 1521 under the influence of the wind, shortening the required airflow path and improving the intake efficiency of the engine 14. When the motorcycle 100 is driven in rainy conditions, the air intake 1211 and grille 1521 also prevent rainwater from entering the air filter 15.

[0034] As one implementation, viewed along the width of the motorcycle 100, the lower edge of the side guard 121 is arranged around at least a portion of the rear air intake 1523, forming a clearance space 103 between the lower edge of the side guard 121 and the outer edge of the rear air intake 1523. As another implementation, the width L1 of the clearance space 103 ranges from 20mm to 40mm. Further, the width L1 of the clearance space 103 ranges from 22.5mm to 37.5mm. More preferably, the width L1 of the clearance space 103 ranges from 25mm to 35mm. It should be noted that since at least part of the engine 14 is connected to the frame 11 via shock absorbers, and the air filter 15 is fixed to the engine 14, during the riding of the motorcycle 100, if the motorcycle 100 experiences bumps, the engine 14 may vibrate along the height direction of the motorcycle 100 under the elastic force of the shock absorbers. Therefore, the width L1 of the clearance space 103 refers to the distance between the lower edge of the side guard plate 121 and the outer edge of the rear air intake cover 1523 in the height direction of the motorcycle 100. If the width L1 of the clearance space 103 is too small, there is a risk of collision between the air filter 15 and the side guard plate 121, affecting the service life of the air filter 15 or the side guard plate 121. If the width L1 of the clearance space 103 is too large, the overall structure of the motorcycle 100 is not compact, which is not conducive to the overall layout of the motorcycle 100. Through the above settings, the service life of the side guard plate 121 and the air filter 15 is improved while ensuring the overall structural compactness of the motorcycle 100.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
