Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, specifically to a motorcycle ram air intake system and a motorcycle. Background Technology

[0002] With increasingly fierce market competition, the performance and safety of large-displacement motorcycles have become key to market competition, and the improvement of motorcycle engine power and body stability is imminent. Ram air intake is an effective technology to improve engine performance. There are three key design points for the performance of motorcycle ram air intake systems: increasing air intake volume, waterproofing, and preventing foreign objects from entering.

[0003] To avoid inhaling excessive rainwater and foreign objects, existing motorcycle ram air intake systems often have small ram air intakes or are designed with grilles or other structures, which limits the increase in air intake volume, resulting in a reduction in the ram air intake area and the amount of air intake reduced.

[0004] Therefore, a new ram air intake system layout is needed to obtain a larger air intake, improve ram air intake efficiency and increase engine power, while reducing the entry of foreign objects, water droplets and other contaminants into the air filter. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a motorcycle ram air intake system and a motorcycle, which adjusts the position and layout of the ram air intake port, increases the ram air intake area, increases the air intake volume, and at the same time reduces the entry of foreign objects, water droplets, etc. into the air filter.

[0006] The motorcycle ram air intake system and motorcycle provided by this utility model adopt the following technical solution:

[0007] A motorcycle ram air intake system includes an air intake, an air filter, and an air intake connecting pipe for connecting the air intake and the air filter. The air intake is located at the front of the motorcycle. The air intake connecting pipe is provided with a front air intake section connected to the air intake and a rear air intake section connected to the air filter. The front air intake section is inclined forward and downward, and the bottom plate of the rear air intake section is provided with a drain hole.

[0008] By adopting the above technical solution, the air intake opening is located at the front of the motorcycle. This position is the stagnation point at the front of the vehicle, where the air velocity is the highest. The surrounding structure is relatively simple, allowing for the design of a larger ram air intake to increase the air volume. At the same time, the front section of the air intake connection pipe is designed to face downwards, which can prevent larger foreign objects such as stones from entering the air intake connection pipe and being directly sucked into the air filter. Meanwhile, the drain hole can ensure the timely discharge of stones and water droplets that enter the rear section of the air intake connection pipe. The airflow direction at the drain hole opening is perpendicular to the opening direction, so only a small amount of air will flow out from the drain hole, which has little impact on the air intake efficiency.

[0009] Furthermore, the intake connecting pipe passes between the front shock absorbers and splits into two at the steering column pillar, bypassing the steering column pillar to form two intake sections that connect to the two inlets of the air filter.

[0010] By adopting the above technical solution, the intake connection pipe is placed in the middle of the front shock absorber of the motorcycle. The rear section of the intake pipe is split into two at the position of the steering column pillar, passes through the frame, and is directly connected to the air filter inlet. This ensures that the stamped intake connection pipe is relatively short and has a large space in the middle, which increases the cross-sectional area of ​​the pipe and reduces the flow resistance of the pipe, allowing the airflow entering from the intake port to pass through the intake connection pipe quickly.

[0011] Furthermore, a baffle is provided on the bottom plate of the rear section of the air intake connection pipe, and the baffle is bent along the curvature of the rear section of the air intake.

[0012] By adopting the above technical solution, the baffle is located at the middle of the bottom of the intake connecting pipe, which evenly divides the air intake channel of the rear section of the intake connecting pipe into two channels. The baffle is parallel to the flow direction, changing the rear section of the intake connecting pipe from two channels to four channels. Since the high-speed airflow changes direction when it is split in the rear section of the intake connecting pipe, water droplets or foreign objects in the air will also change direction with the air. Therefore, by utilizing the adsorption property of water droplets, water droplets will be adsorbed on the surface of the baffle after hitting the baffle. At the same time, after foreign objects hit the baffle, their forward inertia will be reduced and they will fall to the bottom of the intake connecting pipe. The high-speed air will continue to flow towards the air filter along the flow channel formed by the baffle, reducing the flow resistance of the rear section of the intake connecting pipe, guiding the airflow to enter the air filter more smoothly, improving the intake efficiency, and thus improving the engine power, so as to achieve the purpose of waterproofing and preventing foreign objects without affecting the intake.

[0013] Furthermore, the end of the partition facing the front of the vehicle extends inward along the front section of the air intake connection pipe.

[0014] By adopting the above technical solution, the airflow can be better guided into the rear section of the intake connection pipe.

[0015] Furthermore, the side of the partition is provided with several raised ribs.

[0016] By adopting the above technical solution, the raised ribs can guide the water flow on the surface of the partition to flow downwards to the bottom of the air intake connection pipe.

[0017] Furthermore, a splash-proof water-absorbing pad I is provided on the bottom plate of the air intake section of the air intake connecting pipe, and a splash-proof water-absorbing pad II is provided on the inner wall of the air intake connecting pipe diversion point.

[0018] By adopting the above technical solution, the anti-splash absorbent pad I can absorb water droplets mixed with air entering from the air inlet, and the anti-splash absorbent pad II can absorb water droplets mixed with air entering the air inlet connecting pipe, preventing water droplets from splashing everywhere after hitting the inner wall of the air inlet connecting pipe, and allowing them to flow along the bottom surface as much as possible. At the same time, it can also buffer foreign objects such as stones, reduce the impact of stones on the air inlet connecting pipe, reduce the abnormal noise of stone impact, and slow down the inertia of stones continuing to move into the air inlet connecting pipe.

[0019] Furthermore, the air intake is located on the front panel of the motorcycle and below the windshield.

[0020] By adopting the above technical solution, the air intake opening is located below the windshield. This position is the stagnation point at the front of the vehicle, which is the point with the highest airflow velocity. Moreover, the surrounding structure is relatively simple, and a larger ram air intake can be designed.

[0021] Furthermore, a guide plate is provided laterally inside the air inlet, and the distance between the guide plate and the lower inner wall of the air inlet is greater than the distance between the guide plate and the upper inner wall of the air inlet.

[0022] By adopting the above technical solution, the deflector is airfoil-shaped. According to Bernoulli's principle, the airflow velocity on the lower surface is greater than that on the upper surface, and the pressure on the lower surface is lower than that on the upper surface, thus generating downforce. Furthermore, because the air intake is located in the positive pressure area at the front of the vehicle, the faster the vehicle speed, the greater the wind speed, the greater the pressure difference, and the greater the downforce provided at the front of the vehicle, which can improve the stability of the vehicle during extreme driving. On the other hand, the deflector can also prevent larger foreign objects from entering the air intake connection pipe.

[0023] Furthermore, the intake connecting pipe includes an upper connecting pipe and a lower connecting pipe that can be fastened together. The upper connecting pipe has a positioning boss on its edge, and the lower connecting pipe has a positioning groove on its edge that engages with the positioning boss.

[0024] By adopting the above technical solution, the partition and the lower connecting pipe are integrally formed, and the top of the partition is 2mm away from the wall of the upper connecting pipe to avoid installation interference. The processing is simple and does not require additional molds, which can save development costs. The positioning boss and positioning groove mesh with each other to position the assembly of the upper and lower connecting pipes. At the same time, self-tapping screws are designed on the edges of the upper and lower connecting pipes to lock the upper and lower connecting pipes in place and prevent relative sliding.

[0025] A motorcycle including the motorcycle ram air intake system described above.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. The air intake opening is located at the front of the motorcycle. This position is the stagnation point at the front of the vehicle and the point with the highest airflow velocity. The surrounding structure is relatively simple, so a larger ram air intake can be designed. The front section of the air intake connection pipe is designed to face downwards to prevent large foreign objects such as stones from being directly sucked into the air filter.

[0028] 2. The stamped air intake connecting pipe is placed between the front shock absorber and the upper and lower connecting plates. At the position of the steering column pillar, the stamped air intake connecting pipe is split into two, passes through the frame, and is directly connected to the air filter inlet, ensuring that the stamped air intake connecting pipe is relatively short and has a large space in the middle.

[0029] 3. The baffle is parallel to the flow direction, changing the rear section of the ram air intake connection pipe from a two-channel to a four-channel design. This reduces the flow resistance of the rear section of the ram air intake connection pipe, guides the airflow to enter the air filter more smoothly, improves intake efficiency, and thus increases engine power.

[0030] 4. The airflow velocity on the lower surface of the deflector is greater than that on the upper surface, and the pressure on the lower surface is lower than that on the upper surface, which in turn generates downforce. Because the air intake is located in the positive pressure area at the front of the vehicle, the faster the vehicle speed, the greater the wind speed, the greater the pressure difference, and the greater the downforce provided to the front of the vehicle, which can improve the stability of the vehicle when driving at its limit. On the other hand, the deflector can also prevent larger foreign objects from entering the air intake connection pipe. Attached Figure Description

[0039] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0040] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0041] This utility model discloses a motorcycle ram air intake system and a motorcycle. (See reference...) Figures 1-6 The motorcycle ram air intake system includes an air intake 1, an air filter 2, and an intake connecting pipe 3 connecting the air intake 1 and the air filter 2. The air intake 1 is located at the front of the motorcycle. The intake connecting pipe 3 has a front intake section connected to the air intake 1 and a rear intake section connected to the air filter 2. The front intake section is inclined forward and downward, and the bottom plate of the rear intake section has a drain hole 7. The opening of the air intake 1 is located at the front of the motorcycle, which is the stagnation point at the front of the vehicle, the point with the highest air velocity, and the surrounding structure is relatively simple. The air inlet 1 is designed to be relatively large, and the front section of the air intake connecting pipe 3 is designed to face downwards, which can prevent large foreign objects such as stones from being directly sucked into the air filter 2. At the same time, the drain hole 7 can ensure that stones and water droplets entering the rear section of the air intake connecting pipe 3 are discharged in time. The airflow direction at the opening of the drain hole 7 is perpendicular to the opening direction, and only a small amount of air will flow out from the drain hole 7, which has little impact on the air intake efficiency. The width of the drain hole 7 is greater than the width of the bottom plate plane, which can discharge foreign objects on the bottom plate and avoid the situation where the drain hole 7 is too small to completely discharge.

[0042] In this embodiment, the intake connecting pipe 3 passes between the front shock absorbers and splits into two at the steering column pillar, bypassing the steering column pillar to form two intake sections that connect to the two inlets of the air filter 2. The intake connecting pipe 3 is placed between the front shock absorber and the upper and lower connecting plates of the front shock absorber. The intake section splits into two at the steering column pillar position, passes through the frame, and connects directly to the inlet of the air filter 2. This ensures that the intake connecting pipe 3 is relatively short and has a large space in the middle, increasing the cross-sectional area of ​​the pipe and reducing the flow resistance of the pipe, so that the airflow entering from the intake port 1 can quickly pass through the intake connecting pipe 3.

[0043] In this embodiment, a baffle 4 is provided on the bottom plate of the rear section of the intake connecting pipe 3. The baffle 4 is perpendicular to the bottom plate of the intake connecting pipe 3 and is bent along the curvature of the rear section of the intake connecting pipe 3. The baffle 4 is located in the middle of the bottom of the intake connecting pipe 3, which evenly divides the flow channel of the rear section of the intake connecting pipe 3 into two channels. The baffle 4 is parallel to the flow direction, changing the rear section of the intake connecting pipe 3 from two channels to four channels. Since the high-speed airflow changes direction when it is split in the rear section of the intake connecting pipe 3, water droplets or foreign objects in the air will also change direction with the air. Therefore, taking advantage of the adsorption property of water droplets, the water droplets will be adsorbed after hitting the baffle 4. When a foreign object impacts the baffle 4, its forward momentum is reduced, causing it to fall to the bottom of the intake connecting pipe 3. The high-speed air continues to flow towards the air filter 2 along the flow channel formed by the baffle 4. The rear end of the baffle 4 extends 30mm beyond the intake section of the intake connecting pipe 3, guiding the surface water flow to the bottom of the pipe. This prevents the water from leaving the end of the baffle 4 too early and re-mixing into the high-speed airflow, which would then be drawn into the air filter 2. This reduces the flow resistance of the intake section of the intake connecting pipe 3, guiding the airflow to enter the air filter 2 more smoothly, improving intake efficiency, and thus increasing engine power. This achieves the purpose of waterproofing and preventing foreign objects from entering the engine without affecting the intake.

[0044] In this embodiment, the end of the partition 4 facing the front of the vehicle extends into the front section of the air intake connection pipe 3, which can better guide the airflow into the rear section of the air intake connection pipe 3.

[0045] In this embodiment, the side of the partition 4 is provided with a number of raised ribs 41 for guiding the surface water to flow downward to the bottom of the air inlet connecting pipe 3, and the height of the raised ribs 41 is greater than 1mm.

[0046] In this embodiment, a splash-proof water-absorbing pad I5 is provided on the bottom plate of the air intake section of the air intake connection pipe 3, and a splash-proof water-absorbing pad II6 is provided on the inner wall of the air intake connection pipe 3 at the diversion point. The splash-proof water-absorbing pad I5 can absorb water droplets mixed in the air entering from the air intake port 1, and the splash-proof water-absorbing pad II6 can absorb water droplets mixed in the air entering the air intake connection pipe 3. Both the splash-proof water-absorbing pad I5 and the splash-proof water-absorbing pad II6 are sponge pads, or they can be made of materials that can absorb water and cushion, such as cloth, to prevent water droplets from splashing everywhere after hitting the inner wall of the air intake connection pipe 3, and to flow along the bottom surface as much as possible. At the same time, it can also buffer foreign objects such as stones, reduce the impact of stones on the air intake connection pipe 3, reduce the abnormal noise of stone impact, and slow down the inertia of stones continuing to move into the air intake connection pipe 3.

[0047] In this embodiment, the width of the drain hole 7 is greater than the width of the bottom plate plane, and the length of the drain hole 7 is greater than 10mm. The width of the drain hole 7 being greater than the width of the bottom plate plane can discharge foreign objects on the bottom plate, avoiding the situation where the drain hole 7 is too small to completely discharge them.

[0048] In this embodiment, the air intake 1 is located on the front panel of the motorcycle and below the windshield. The air intake 1 is located in the middle of the mounting holes of the left and right rearview mirrors. This position is the stagnation point at the front of the vehicle, which is the point with the highest air velocity. Moreover, the surrounding structure is relatively simple, so a larger air intake 1 can be designed to increase the air intake volume.

[0049] In this embodiment, a guide vane 8 is arranged laterally inside the air intake 1. The distance between the guide vane 8 and the lower inner wall of the air intake 1 is greater than the distance between the guide vane 8 and the upper inner wall of the air intake 1. The guide vane 8 is airfoil-shaped. According to Bernoulli's principle, the airflow velocity on the lower surface is greater than that on the upper surface, and the pressure on the lower surface is lower than that on the upper surface, thus generating downforce. Since the air intake 1 is located in the positive pressure area at the front of the vehicle, the faster the vehicle speed, the greater the wind speed and the greater the pressure difference, the greater the downforce provided at the front of the vehicle, which can improve the stability of the vehicle during extreme driving. On the other hand, the guide vane 8 can also prevent larger foreign objects from entering the air intake connecting pipe 3.

[0050] In this embodiment, the intake connecting pipe 3 includes an upper connecting pipe 31 and a lower connecting pipe 32 that can be fastened together. The edge of the upper connecting pipe 31 is provided with a positioning boss 311, and the edge of the lower connecting pipe 32 is provided with a positioning groove 321 that meshes with the positioning boss 311. A partition 4 is provided on the lower connecting pipe 32. The partition 4 and the lower connecting pipe 32 are integrally formed. The top of the partition 4 is 2mm away from the wall of the upper connecting pipe 31 to avoid installation interference. The processing is simple and does not require additional molds, thus saving development costs. The positioning boss 311 and the positioning groove 321 mesh with each other to position the assembly of the upper connecting pipe 31 and the lower connecting pipe 32. At the same time, self-tapping screws are designed on the edges of the upper connecting pipe 31 and the lower connecting pipe 32 to lock the upper connecting pipe 31 and the lower connecting pipe 32 in place and prevent relative sliding.
