[0030] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0031] A motorcycle provided by an embodiment of the present application includes a frame, a helmet box 20, and an air filter assembly 10. The helmet box 20 is installed on the frame, and the air filter assembly 10 is installed on the helmet box 20. The air filter assembly 10 is in communication with the engine cylinder.

[0032] In one embodiment, referring to Figure 2 , the air filter assembly 10 includes an intake connection pipe 11, an intake pipe 12, and an air filter. One end of the intake connection pipe 11 is disposed in the assembly hole of the helmet box 20, the other end of the intake connection pipe 11 is in communication with the intake pipe 12, and the end of the intake pipe 12 facing away from the intake connection pipe 11 is in communication with the air filter. During the running of the motorcycle, air enters the air filter through the intake connection pipe 11 and the intake pipe 12. The air filter can filter the air, so that the air entering the engine combustion chamber remains clean, reducing the wear of the engine cylinder piston and extending the service life of the engine.

[0033] By installing the intake connection pipe 11 on the helmet box 20, the position of the air inlet 1111 of the air filter assembly 10 is relatively high, which can prevent the dust on the road surface from being sucked into the air filter and causing the air filter to be blocked, avoid abnormal increase in the fuel consumption of the motorcycle, and at the same time can also avoid abnormal wear of the engine and extend the service life of the engine.

[0034] In one embodiment, referring to Figure 2 , the intake pipe 12 is a flexible pipe. Optionally, the intake pipe 12 is a corrugated pipe. In this way, the orientation of the intake pipe 12 can be adjusted according to the use requirements, and the use is flexible. Of course, in other embodiments, the intake pipe 12 can also be a pipe made of other materials, and is not limited thereto.

[0035] In one embodiment, referring to Figure 1 , the intake connection pipe 11 includes a main pipe body 111, a first branch pipe body 112, and a second branch pipe body 113. One end of the main pipe body 111 is disposed in the assembly hole, the main pipe body 111 is provided with an air inlet 1111, and the air inlet 1111 is in communication with the assembly hole. The first branch pipe body 112 and the second branch pipe body 113 are both disposed at the end of the main pipe body 111 facing away from the air inlet 1111, and both the first branch pipe body 112 and the second branch pipe body 113 are in communication with the main pipe body 111.

[0036] Further, referring to Figure 1, the first branch pipe body 112 is arranged on one side of the main pipe body 111 along the first direction. It can be understood that the first direction is the axial direction of the main pipe body 111, and the first direction is represented by S. The axial direction of the first branch pipe body 112 is inclined relative to the axial direction of the main pipe body 111. An exhaust port 1121 is provided at one end of the first branch pipe body 112 away from the main pipe body 111, and the exhaust port 1121 is communicated with the first branch pipe body 112.

[0037] Further, refer to Figure 1 , the second branch pipe body 113 and the main pipe body 111 are both arranged on the same side of the first branch pipe body 112 along the first direction, and a sewage discharge port is provided at one end of the second branch pipe body 113 away from the main pipe body 111.

[0038] During the running of the motorcycle, air enters the main pipe body 111 and the first branch pipe body 112 through the air inlet 1111, and then enters the intake pipe 12 through the exhaust port 1121. The air in the intake pipe 12 enters the air filter. The air filter can filter the air, so that the air entering the engine combustion chamber remains clean, reducing the wear of the engine cylinder piston and extending the service life of the engine.

[0039] When washing the motorcycle with a large amount of water, the water flow may enter the intake joint pipe 11. Specifically, when the water flow enters the main pipe body 111 through the air inlet 1111, the water flow flows into the second branch pipe body 113 under the action of its own gravity and is then discharged through the sewage discharge port. Since the first branch pipe body 112 is arranged on the side part of the main pipe body 111 along the first direction, this can prevent the water flow from entering the first branch pipe body 112, thereby preventing the water flow from entering the air filter and causing damage to the air filter, and extending the service life of the air filter.

[0040] Dust may also enter the intake joint pipe 11 through the air inlet 1111. Part of the dust accumulates in the second branch pipe body 113 and is discharged through the sewage discharge port. This can prevent the dust from entering the air filter and causing damage to the air filter, and extending the service life of the air filter.

[0041] In one embodiment, refer to Figure 1 , the projection of the wall of the air inlet 1111 on the side close to the first branch pipe body 112 in the first direction is located in the second branch pipe body 113. In this way, it can be ensured that the water flow and dust entering the intake joint pipe 11 through the air inlet 1111 directly fall into the second branch pipe body 113 under the action of their own gravity.

[0042] In one embodiment, refer to Figure 1, one end of the main pipe body 111 away from the air inlet 1111 is provided with a flat wall 118. The flat wall 118 extends in a direction away from the second branch pipe body 113. The flat wall 118 is horizontally arranged, and one end of the first branch pipe body 112 away from the exhaust port 1121 is connected to the flat wall 118. In this way, by providing the flat wall 118, it is possible to prevent water flow from flowing into the first branch pipe body 112.

[0043] In one embodiment, referring to Figure 1 , the air inlet joint pipe 11 further includes a sewage discharge valve 114, and the sewage discharge valve 114 is arranged at the sewage discharge port. Optionally, the sewage discharge valve 114 is a duckbill valve, and the duckbill valve has a one-way conduction function.

[0044] When washing a car with a large water flow, the water flow may enter the air inlet joint pipe 11 through the air inlet 1111. The water flow flows into the second branch pipe body 113 under the action of its own gravity. Under the impact of the water flow, the duckbill valve opens to discharge the sewage.

[0045] Dust will enter the air inlet joint pipe 11 through the air inlet 1111. Part of the dust accumulates in the duckbill valve. When the dust accumulates to a certain amount, the dust will be discharged from the duckbill valve under the action of its own gravity.

[0046] In one embodiment, referring to Figure 1 , the cross-sectional shape of the main pipe body 111 is a special-shaped triangle. With such a setting, while ensuring the air intake volume, it is also possible to minimize the occupied space as much as possible and expand the accommodation space of the helmet box 20.

[0047] Furthermore, the assembly hole is a special-shaped triangle adapted to the cross-sectional shape of the main pipe body 111. With such a setting, it is convenient to install the air inlet joint pipe 11 in the assembly hole.

[0048] Optionally, referring to Figure 1, the outer peripheral surface of the main pipe body 111 includes a first flat portion 1112, a second flat portion 1113, a third flat portion 1114, a first arc portion 1115, a second arc portion 1116, and a third arc portion 1117. The first flat portion 1112 has opposite first and second sides, the second flat portion 1113 has opposite third and fourth sides, the first side and the third side are oppositely arranged, and the second side and the fourth side are oppositely arranged. The third flat portion 1114 is disposed between the first side and the third side, and the third flat portion 1114 has opposite fifth and sixth sides. The first arc portion 1115 is disposed between the first flat portion 1112 and the third flat portion 1114, and both sides of the first arc portion 1115 are respectively connected to the first side and the fifth side. The second arc portion 1116 is disposed between the second flat portion 1113 and the third flat portion 1114, and both sides of the second arc portion 1116 are respectively connected to the third side and the sixth side. The third arc portion 1117 is disposed between the second side and the fourth side, and both sides of the third arc portion 1117 are respectively connected to the second side and the fourth side. Thus, the cross-sectional shape of the main pipe body 111 is a special-shaped triangle.

[0049] Further, the first flat portion 1112 is disposed on the side of the second flat portion 1113 away from the first branch pipe body 112, the first flat portion 1112 is perpendicular to the third flat portion 1114, or the included angle between the first flat portion 1112 and the third flat portion 1114 is greater than 90°.

[0050] In one embodiment, refer to Figure 1 , the intake joint pipe 11 is further provided with mounting ears 13, and the mounting ears 13 are provided with mounting holes 131. During installation, a mounting member is provided in the mounting ears 13, and the intake joint pipe 11 is mounted on the helmet box 20 by using the mounting member.

[0051] Further, there are at least two mounting ears 13. Thus, the firmness and stability of the intake joint pipe 11 mounted on the vehicle frame can be improved.

[0052] Optionally, refer to Figure 1 , there are two mounting ears 13, and the two mounting ears 13 are oppositely arranged. Of course, in other embodiments, the number of mounting ears 13 can also be three, four, five or more, and it is not limited thereto.

[0053] In one embodiment, refer to Figure 2 and Figure 3 , the helmet box 20 includes a box body 21 and a protective cover 221. The protective cover 221 covers the air inlet 1111. An opening 2211 is provided on the side of the protective cover 221, and the opening 2211 is communicated with the air inlet 1111. By providing the protective cover 221, the protective cover 221 can play a protective role and reduce the dirt entering the intake joint pipe 11 through the air inlet 1111.

[0054] In one embodiment, referring to Figure 2 and Figure 3 , the helmet box 20 further includes a cover plate 22, and the cover plate 22 is installed on the box body 21. A protective cover 221 is formed on the cover plate 22. It can be understood that the protective cover 221 is a part of the structure of the cover plate 22. During installation, by installing the cover plate 22 on the box body 21, the installation of the protective cover 221 can be achieved. In this way, the number of components can be reduced, and at the same time, the assembly working hours can be saved.

[0055] In one embodiment, referring to Figure 2 and Figure 3 , the hole wall of the assembly hole extends into the box body 21 to form a protective tube 212 with a certain height. There is a gap between the top of the protective tube 212 and the protective cover 221, and the protective tube 212 communicates with the opening 2211 and the air inlet 1111. In this way, by providing the protective tube 212, the protective tube 212 can play a blocking role to prevent the water and dust accumulated in the helmet box 20 from entering the air inlet joint pipe 11.

[0056] Optionally, the shape of the protective tube 212 is a special-shaped triangle adapted to the cross-sectional shape of the main pipe body 111. With such a setting, while ensuring the air intake volume, the occupied space can be reduced as much as possible, and the accommodation space of the helmet box 20 can be expanded.
