[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0023] like Figure 1 As shown, the present application provides a motorcycle 100, and the motorcycle 100 includes the following basic components, such as: a frame 11, a body cover 12, a running assembly 13, an engine 14 and an intake system 15. Among them, the frame 11 serves as the basic framework of the motorcycle 100, and at least a portion of the body cover 12 is mounted on the frame 11. The running assembly 13 is at least partially located below the frame 11, and the engine 14 is fixedly mounted on the frame 11 and is in transmission connection with the running assembly 13. The engine 14 is used to provide power for the running assembly 13, and at least a portion of the intake system 15 is mounted on the frame 11. In order to clearly illustrate the technical solution of the present application, the following are also defined: Figure 1 Front, back, left, right, top and bottom shown.

[0024] It should be noted that the length direction in the embodiment of the present application refers to the length of the motorcycle 100 in the Figure 1 The front-rear direction in the state shown, the width direction refers to the left-right direction of the motorcycle 100 in the aforementioned state, and the height direction refers to the up-down direction of the motorcycle 100 in the aforementioned state.

[0025] like Figure 2 As shown, as an implementation, the body cover 12 includes a front cover 121, which is mounted on the frame 11 and located at the front of the frame 11. The front cover 121 is used to protect the components at the front of the motorcycle 100, such as the central control system and the air intake system 15 of the motorcycle 100. At least one air intake port 1211 is provided on the front cover 121, and the opening of the air intake port 1211 faces the front of the motorcycle 100. The front cover 121 also includes at least one first air intake channel 1212, which extends substantially along the length direction of the motorcycle 100.

[0026] like Figure 3 As shown, the air intake system 15 includes an air filter 151, which is fixedly connected to the vehicle frame 11. The air filter 151 is located above the engine 14 and connected to the engine 14. The air filter 151 is used to provide air to the engine 14 and filter out dust or debris in the air.

[0027] In the example of the present application, one end of the first air intake passage 1212 is connected to the outside through the air intake port 1211, and the other end of the first air intake passage 1212 is connected to the air filter 151. Since the air intake port 1211 is located at the front of the motorcycle 100, when the motorcycle 100 is running, the windward airflow in front of the motorcycle 100 will enter the first air intake pipe 1212 through the air intake port 1211, and enter the air filter 151 after flowing through the first air intake pipe 1212, and then be transmitted to the engine 14. In particular, when the motorcycle 100 is running at high speed, the wind pressure of the windward airflow is large and the flow rate is fast. Therefore, the above-mentioned setting can increase the intake volume of the air filter 151, so that the fuel mixture in the engine 14 has sufficient oxygen, improve the combustion efficiency of the fuel mixture, and thus improve the performance of the engine 14. It should be noted that the outside refers to the space other than the motorcycle 100 itself.

[0028] Further, along the length direction of the motorcycle 100, the air filter 151 is located behind the front cover 121, and the air filter 151 includes an air filter body 1511 and a second air intake passage 1512. The air filter body 1511 is used to filter out particulate impurities in the air to ensure that the air entering the engine 14 is clean and to prevent larger particles from entering the engine 14 and burning, thereby causing a malfunction of the engine 14. The second air intake passage 1512 extends substantially along the length direction of the motorcycle 100, and the second air intake passage 1512 is arranged between the air filter body 1511 and the first air intake passage 1212. One end of the second air intake passage 1512 is connected to the air filter body 1511, and the other end of the second air intake passage 1512 is connected to the first air intake passage 1212. Through the above arrangement, the first air intake passage 1212 serves as an extension of the second air intake passage 1512 to shorten the length of the air filter 151, thereby avoiding the second air intake passage 1512 being too long to achieve the ram air intake function of the motorcycle 100 and reducing the difficulty of assembling the air filter 151.

[0029] like Figure 1As shown, as an implementation, the motorcycle 100 further includes a front lighting assembly 16 mounted on the frame 11, and the front lighting assembly 16 is located in front of the frame 11. The front cover 121 is distributed around the front lighting assembly 16, and at least part of the air inlet 1211 is located below the front lighting assembly 16, and the front cover 121 is used to protect the front lighting assembly 16. In order to meet the lighting standard of the motorcycle 100, the front lighting assembly 16 is arranged at a higher position, that is, along the height direction of the motorcycle 100, at least part of the front lighting assembly 16 is located above the air filter 151. By arranging the air inlet 1211 located below the front lighting assembly 16, the height of the air inlet 1211 is substantially consistent with the height of the air filter 151, so that the first air inlet channel 1212 and the second air inlet channel 1512 can be basically extended along the length direction of the motorcycle 100, thereby reducing the bending of the first air inlet channel 1212 and the second air inlet channel 1512, and improving the air intake efficiency of the air filter 151.

[0030] like Figure 4 As shown, as an implementation, the first air intake channel 1212 and the second air intake channel 1512 form a ram air intake channel 1513 of the motorcycle 100, and the ram air intake channel 1513 extends substantially along the length direction of the motorcycle 100. During the running of the motorcycle 100, air can enter the air filter body 1511 through the ram air intake channel 1513. By providing the ram air intake channel 1513 extending substantially along the length direction of the motorcycle 100, the air pressure loss generated when the air is transmitted in the ram air intake channel 1513 can be avoided, the flow rate of the air in the ram air intake channel 1513 is ensured, and the air intake efficiency of the air filter 151 is improved.

[0031] like Figure 4As shown, as an implementation, the length of the first air intake channel 1212 extending along the length direction of the motorcycle 100 is defined as the first length L1, and the length of the ram air intake channel 1513 extending along the length direction of the motorcycle 100 is defined as the second length L2, and the ratio between the first length L1 and the second length L2 ranges from 0.45 to 0.74. Further, the ratio between the first length L1 and the second length L2 ranges from 0.48 to 0.7. More preferably, the ratio between the first length L1 and the second length L2 is 0.6. It should be noted that, due to the influence of factors such as the structure of the frame 11, the arrangement of the engine 14, and the size of the air filter 151, the installation position of the air filter 151 is basically fixed, and the length of the ram air intake channel 1513 is restricted by the installation position of the air filter 151 and cannot be greatly adjusted. Therefore, when the ratio between the first length L1 and the second length L2 is too large, the length of the first air intake channel 1212 extending along the length direction of the motorcycle 100 is longer. Since the front cover 121 is usually manufactured by injection molding, if the length of the first air intake channel 1212 is long, it will be difficult to manufacture the first air intake channel 1212. In addition, when the ratio between the first length L1 and the second length L2 is too small, the length of the first air intake channel 1212 extending along the length direction of the motorcycle 100 is short, that is, the length of the second air intake channel 1512 extending along the length direction of the motorcycle 100 is long, which makes it difficult to assemble the air filter 151. Through the above arrangement, the convenience of assembling the air filter 151 is improved, and the mold manufacturing of the front cover 121 is facilitated.

[0032] like Figure 4 As shown, as an optional implementation, the number of ram air inlet channels 1513 is two, and the number of air inlets 1211 is consistent with the number of ram air inlet channels 1513, that is, one ram air inlet channel 1513 is connected to one air inlet 1211. Observing along the height direction of the motorcycle 100, the two air inlets 1211 are respectively located on both sides of the front lighting assembly 16, thereby avoiding interference between the ram air inlet channel 1513 and the front lighting assembly 16, thereby improving the rationality of the layout of the front part of the motorcycle 100.

[0033] Specifically, a longitudinal plane 101 perpendicular to the width direction of the motorcycle 100 is defined, the longitudinal plane 101 substantially divides the frame 11 in half, and the two ram air intake channels 1513 and the two air inlets 1211 are symmetrically distributed about the longitudinal plane 101. Since the outside air needs to enter the air filter body 1511 through the two ram air intake channels 1513 during the driving process of the motorcycle 100, by setting the two ram air intake channels 1513 symmetrically distributed about the longitudinal plane 101, the flow rate of the air entering the two ram air intake channels 1513 can be substantially consistent, thereby preventing the flow rate of the air in one ram air intake channel 1513 from being too high and affecting the flow rate of the air in the other ram air intake channel 1513, thereby improving the stability of the air filter 151.

[0034] Optionally, the air inlet 1211 can also be provided as one, in which case both ram air inlet channels 1513 are communicated with the same air inlet 1211, which is located at the frontmost portion of the front cover 121 and at least partially located below the front lighting assembly 16. Since the windward airflow at the frontmost portion of the front cover 121 has a greater wind pressure and a faster flow rate, the air inlet 1211 provided at the frontmost portion of the front cover 121 can increase the air intake volume of the air filter 151, thereby improving the performance of the engine 14.

[0035] like Figure 5 As shown, as an implementation method, the first air intake channel 1212 is connected to the second air intake channel 1512, and the port of the first air intake channel 1212 is communicated with the port of the second air intake channel 1512, wherein the position where the first air intake channel 1212 and the second air intake channel 1512 are connected are respectively provided with a limiting protrusion 1212a and a limiting groove 1512a that cooperate with each other.

[0036] In the embodiment of the present application, the first air inlet channel 1212 and the second air inlet channel 1512 are both made of hard material (such as plastic), and the first air inlet channel 1212 and the second air inlet channel 1512 are connected by hard connection. The first air inlet channel 1212 is provided with a plurality of limiting protrusions 1212a, and the second air inlet channel 1512 is provided with a limiting groove 1512a that matches the limiting protrusions 1212a. When the first air inlet channel 1212 and the second air inlet channel 1512 are connected to form a ram air inlet channel 1513, the limiting protrusions 1212a on the first air inlet channel 1212 and the limiting groove 1512a on the second air inlet channel 1512 can be mutually engaged to relatively fix the first air inlet channel 1212 and the second air inlet channel 1512. Through the above arrangement, the connection stability between the first air inlet channel 1212 and the second air inlet channel 1512 is improved.

[0037] like Figure 6As shown, in addition to connecting the first intake passage 1212 and the second intake passage 1512 in a hard - connected manner, the present application also provides another alternative implementation to connect the first intake passage 1212 and the second intake passage 1512. Specifically, the intake system 15 further includes a connecting structure 152. The connecting structure 152 is disposed between the first intake passage 1212 and the second intake passage 1512, and both sides of the connecting structure 152 are soft - connected to the first intake passage 1212 and the second intake passage 1512 respectively.

[0038] Specifically, the connecting structure 152 is substantially in the shape of a hollow cylinder. The first intake passage 1212 is connected to the second intake passage 1512 through the connecting structure 152. The connecting structure 152 is respectively provided with a first limiting portion 1521 and a second limiting portion 1522 on both sides facing the first intake passage 1212 and the second intake passage 1512. The connecting structure 152 is connected to the first intake passage 1212 through the first limiting portion 1521, and the connecting structure 152 is also connected to the second intake passage 1512 through the second limiting portion 1522.

[0039] In the embodiment of the present application, a protrusion is provided at one end of the first intake passage 1212 close to the connecting structure 152, and a protrusion is also provided at one end of the second intake passage 1512 close to the connecting structure 152. Both the first limiting portion 1521 and the second limiting portion 1522 are grooves capable of being snap - fitted with the protrusion. When the connecting structure 152 is connected to the first intake passage 1212 and the connecting structure 152 is connected to the second intake passage 1512, the protrusion can be snap - fitted with the recess to connect the connecting structure 152 to the first intake passage 1212 and the second intake passage 1512.

[0040] As an implementation method, the material of the connection structure 152 is a rubber material. Since the first air intake channel 1212 and the second air intake channel 1512 are both made of hard materials, after the first air intake channel 1212 and the second air intake channel 1512 are directly connected, if the motorcycle 100 vibrates during driving, the relative position of the first air intake channel 1212 and the second air intake channel 1512 may change, thereby causing a gap to appear at the connection between the first air intake channel 1212 and the second air intake channel 1512, and the air in the first air intake channel 1212 and the second air intake channel 1512 will flow out from the gap, thereby reducing the amount of air entering the air filter body 1511, thereby reducing the air intake efficiency of the air filter 151. By providing a connecting structure 152 made of rubber material, and connecting the first air intake channel 1212 with the second air intake channel 1512 through the connecting structure 152, if the motorcycle 100 vibrates during driving, causing the relative positions of the first air intake channel 1212 and the second air intake channel 1512 to change, the connecting structure 152 can be deformed to avoid a gap at the connection between the first air intake channel 1212 and the second air intake channel 1512, thereby preventing the air in the first air intake channel 1212 and the second air intake channel 1512 from flowing out of the gap, thereby improving the reliability of the first air intake channel 1212 and the second air intake channel 1512.

[0041] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
