[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments.

[0022] Reference Figure 1-2 , the utility model provides the following technical solutions:

[0023] In the present embodiment, the air filter assembly with multi-intake branch pipes comprises an air filter 3 adapted for a motorcycle and an intake pipe 1 connected to an air inlet 2 of the air filter, wherein the intake pipe 1 comprises a single-pipe section 4 and a multi-pipe section connected to the single-pipe section 4 and composed of a plurality of intake branches, wherein the multi-pipe section is connected to the air inlet 2 of the air filter 3; in the present utility model, the combination adopted by the intake pipe 1 is that the single-pipe section 4 is transformed into a multi-pipe section, so as to optimize the air intake volume and noise reduction of the motorcycle. In practice, different types of motorcycles have different improvements in the air intake volume performance. On the basis of the intake pipe 1 adopting the single-pipe section 4 transformed into a multi-pipe section, it is possible to select a multi-pipe section transformed into a multi-pipe section with more intake branches, a multi-pipe section transformed into a single-pipe section, or a multi-stage arrangement of the intake pipe sections.

[0024] In this embodiment, the air filter 3 includes an air filter case and a filter element group 11 installed in the case. The air inlet 2 includes a plurality of air inlets 2 arranged in the air filter case and corresponding to the multi-way air intake pipes. The size of the air filter case can be selected according to the increase in the air intake volume and the adapted motorcycle model to select an appropriate case volume, which is beneficial to the air intake and filtering.

[0025] In this embodiment, the flow area of ​​the single-pipeline segment 4 is larger than the flow area of ​​the intake branch pipe, and the sum of the flow areas of the multi-pipeline segment composed of multiple intake branch pipes is smaller than the flow area of ​​the single-pipeline segment 4; in the process of transforming from the single-pipeline segment 4 to the multi-pipeline segment, the flow area of ​​the air changes from large to small. Under the condition of constant temperature, the air pressure and the flow area are inversely proportional, that is, the greater the air pressure, the smaller the flow area, and the smaller the air pressure, the larger the flow area. The flow area of ​​the single-pipeline segment 4 is transformed into a smaller multi-pipeline segment, which increases the air pressure in the pipe and thus increases the intake volume.

[0026] In the present embodiment, the single-pipeline segment 4 and the multi-pipeline segment are integrally formed, and the air intake pipe 1 composed of the single-pipeline segment 4 and the multi-pipeline segment is assembled by connecting the upper and lower plastic parts by screws after injection molding. The single-pipeline segment 4 and the multi-pipeline segment are machined by various methods, such as stamping, casting, etc., which can improve the hardness and strength of the air intake pipe, make it more sturdy and durable, have good structural stability, and can better withstand the increased air pressure in the multi-pipeline segment.

[0027] In this embodiment, the multi-pipeline section includes two air intake branches, namely a first air intake branch 5 and a second air intake branch 6, which are arranged in the same horizontal plane and are symmetrical to each other; the first air intake branch 5 and the second air intake branch 6 are correspondingly provided with a first air inlet 7 and a second air inlet 8, and the first air intake branch 5 and the second air intake branch 6 are respectively connected with the corresponding first air inlet 7 and the second air inlet 8, and the single-pipeline section 4 is connected with the first air intake branch 5 and the second air intake branch 6 at the connection points, respectively, using a smooth arc-shaped pipeline transition to play a diversion role; after the single-pipeline section 4 is connected with the first air intake branch 5 and the second air intake branch 6, the projection of the overall air intake pipe section on the ground is Y-shaped.

[0028] In this embodiment, the interior of the air filter case is divided into two chambers with the filter element group 11 as the boundary. The air inlet side of the filter element group is the first chamber 9, and the air outlet side is the second chamber 10; the volume of the first chamber 9 is smaller than the volume of the second chamber 10, and the inner wall of the first chamber 9 is affixed with sound-absorbing foam 12. According to the actual noise reduction effect, the sound-absorbing foam 12 can be affixed to the inner wall of each airway, chamber, and trachea, and is not limited to sound-absorbing foam, but can be other sound-absorbing or sound-absorbing materials, which can better eliminate the vibration and noise of gas flowing, disturbing, and impacting on the pipe wall.

[0029] In this embodiment, by utilizing the running speed of the motorcycle itself, air rushes into the intake pipe 1 at high speed from the front of the motorcycle body, passes through the single-pipe section 4 and is divided into the first intake branch pipe 5 and the second intake branch pipe 6 in the multi-pipe section, enters the air filter box from the corresponding first air inlet 7 and the second air inlet 8 to reach the first chamber 9, enters the second chamber 10 after being filtered by the filter element group 11 in the air filter box, and finally enters the motorcycle engine through the ventilation pipe; the pipelines and flow areas through which the gas passes are from large to small, and from small to large; through the changes in the flow areas of each pipeline and chamber, the silencing effect of the intake noise can be effectively achieved, especially in the expansion and scaling of the flow area from the single-pipe section 4 to the multi-pipe section of the intake pipe 1, the noise reduction is more effective.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
