[0027] like Figures 1 to 2 As shown, a motorcycle frame according to a preferred embodiment of the present invention includes a frame body 10, the frame body 10 includes a first side tube 20, a second side tube 40 and an intake pipe 30, a mounting cavity 13 is formed between the first side tube 20 and the second side tube 40, the front end of the first side tube 20 and the front end of the second side tube 40 are respectively connected to the intake pipe 30, the rear end of the first side tube 20 and the rear end of the second side tube 40 extend backward, the intake pipe 30 is provided with an air inlet 31, the lower end of the intake pipe 30 is located at the front end of the mounting cavity 13, the intake pipe 30 is connected to the first side tube 20, the first side tube 20 is connected to the outlet pipe 21, and the air inlet 31 is connected to the outlet pipe 21 through the intake pipe 30 and the first side tube 20 to form an air channel 11.

[0028] In the motorcycle frame of the present invention, air enters from the air inlet 31 of the air intake pipe 30. The lower end of the air intake pipe 30 is located at the front end of the installation cavity 13. The air intake pipe 30 is connected to the first side pipe 20, so that the first side pipe 20 becomes a part of the air passage 11. The air passage 11 is arranged away from the installation cavity 13, thereby optimizing the space within the installation cavity 13, making the space within the installation cavity 13 more convenient to utilize, and facilitating the arrangement of batteries, wiring harnesses, throttle cables, rear brake cables, etc. within the installation cavity 13.

[0029] Further, such as Figure 2 As shown, the air intake pipe 30 includes a main air pipe 32 and a front cross pipe 33. The front ends of the first side pipe 20 and the second side pipe 40 are respectively connected to the main air pipe 32. The air intake port 31 is opened in the main air pipe 32. The lower end of the main air pipe 32 is connected to the front cross pipe 33. The front cross pipe 33 is located at the front end of the installation cavity 13. One end of the front cross pipe 33 is connected to the first side pipe 20, and the other end of the front cross pipe 33 is connected to the second side pipe 40. The other end of the front cross pipe 33 is not connected to the second side pipe 40, and the lower end of the main air pipe 32 is connected to the front cross pipe 33. The front cross pipe 33 is located at the front end of the installation cavity 13. The air inlet 31 is opened in the main air pipe 32. The main air pipe 32, the front cross pipe 33, the first side pipe 20 and the air outlet pipe 21 are connected in sequence to form an air channel 11. Air enters the main air pipe 32 from the air inlet 31 and is discharged from the air outlet pipe 21, so that the air channel 11 is set away from the installation cavity 13, optimizes the space in the installation cavity 13, and makes the space in the installation cavity 13 more convenient to utilize.

[0030] Further, such as Figure 1 As shown, the air intake pipe 30 includes an air guide pipe 34, a main air pipe 32 and a front cross pipe 33. The air intake port 31 is opened in the main air pipe 32. The front end of the first side pipe 20 and the front end of the second side pipe 40 are respectively connected to the main air pipe 32. The main air pipe 32 is connected to the first side pipe 20 through the air guide pipe 34. The lower end of the main air pipe 32 is connected to the front cross pipe 33. The front cross pipe 33 is located at the front end of the installation cavity 13.

The lower end of the main air pipe 32 is connected to the front cross pipe 33, and the front cross pipe 33 is located at the front end of the installation cavity 13. The air inlet 31 is opened in the main air pipe 32. The main air pipe 32, the air guide pipe 34, the first side pipe 20 and the air outlet pipe 21 are connected in sequence to form an air channel 11. The air enters the main air pipe 32 from the air inlet 31 and is discharged from the air outlet pipe 21, so that the air channel 11 avoids the installation cavity 13, optimizes the space in the installation cavity 13, and makes the space in the installation cavity 13 more convenient to use. At the same time, the main air pipe 32 is connected with the first side pipe 20 through the air guide pipe 34, avoiding the opening of the front cross pipe 33 and the left side pipe, improving the structural strength of the front cross pipe 33 and the left side pipe, and adding the air guide pipe 34 reduces the impact on the frame strength to meet the usage requirements.

[0031] Further, such as Figures 1 to 2As shown, the intake pipe 30 includes a main pipe 32 and a front cross pipe 33. The front ends of the first side pipe 20 and the second side pipe 40 are connected to either side of the main pipe 32, respectively. The air intake 31 is located at the upper end of the main pipe 32, and the lower end of the main pipe 32 is connected to the front cross pipe 33. The ends of the front cross pipe 33 are respectively connected to the first side pipe 20 and the second side pipe 40. The first side pipe 20, the second side pipe 40, and the front cross pipe 33 form a triangular structure, which improves the structural stability of the vehicle frame.

[0032] Further, such as Figures 1 to 2 As shown, the frame body 10 includes a rear cross tube 12, the two ends of which are respectively connected to the first side tube 20 and the second side tube 40. The front cross tube 33, the rear cross tube 12, the first side tube 20 and the second side tube 40 enclose a mounting cavity 13. The air channel 11 avoids the location of the mounting cavity 13, making the space within the mounting cavity 13 more convenient for layout.

[0033] Further, such as Figures 1 to 2 As shown, the lower end of the main air pipe 32 is connected to the middle of the front cross pipe 33, and the force applied to the main air pipe 32 in the front cross pipe 33 is more uniform, thereby improving the stability of the connection structure.

[0034] Further, such as Figures 1 to 2 As shown, the air outlet pipe 21 is located outside the first side pipe 20 , and the air outlet pipe 21 is arranged away from the installation cavity 13 to optimize the space of the installation cavity 13 .

[0035] Further, such as Figures 1 to 2 As shown, the air outlet pipe 21 is located at the rear side of the installation cavity 13 . The air outlet pipe 21 is arranged away from the installation cavity 13 to optimize the space of the installation cavity 13 .

[0036] Further, such as Figures 1 to 2 As shown, the air outlet pipe 21 is provided with an exhaust port 22 for communicating with the engine clutch chamber 50 , and the air outlet pipe 21 is communicated with the engine clutch through the exhaust port 22 .

[0037] Further, such as Figures 1 to 2 As shown, the exhaust port 22 is connected to a flexible tube 23 for communicating with the engine clutch chamber 50 , and the exhaust pipe 21 is connected to the engine clutch chamber 50 through the flexible tube 23 , thereby improving the convenience of the connection operation.

[0038] As one embodiment, the flexible tube 23 is a rubber tube, which helps to enhance the lightweight design of the frame.

[0039] In summary, an embodiment of the present invention provides a motorcycle frame, wherein air enters from the air inlet 31 of the air intake pipe 30, the lower end of the air intake pipe 30 is located at the front end of the mounting cavity 13, and the air intake pipe 30 is connected to the first side pipe 20, so that the first side pipe 20 becomes a part of the air channel 11, and the air channel 11 is arranged to avoid the mounting cavity 13, thereby optimizing the space within the mounting cavity 13, making the space within the mounting cavity 13 more convenient to utilize, and facilitating the arrangement of batteries, wiring harnesses, throttle cables, rear brake cables, etc. within the mounting cavity 13.
