Technical Field

[0001] This application relates to the field of motorcycle technology, and in particular to a waterproof air filter structure and a motorcycle. Background Technology

[0002] Motorcycles and other internal combustion vehicles are usually equipped with air filters. As a key protective component of the engine, the air filter is mainly used to filter impurities in the air and ensure the reliable operation of the engine.

[0003] Currently, motorcycles consist of a main body and a fuel tank, seat, and air filter, all mounted on the main body. The air filter's intake pipe is located under the seat, and the front of the seat connects to the fuel tank. However, when riding a motorcycle in the rain, water may seep from the connection between the seat and the fuel tank into the area under the seat and be sucked into the air filter, affecting the normal operation of the engine. Utility Model Content

[0004] This application provides a waterproof air filter structure and a motorcycle. Water seeps into the underside of the seat from the junction of the seat and the fuel tank, making it less likely to be drawn into the air filter, thus ensuring the normal operation of the engine.

[0005] In a first aspect, embodiments of this application provide a waterproof structure for an air filter, comprising:

[0006] An air filter is provided with an air intake pipe. A first baffle is provided on the outer periphery of the air intake pipe. The first baffle extends from the left side of the air intake pipe, through the top of the air intake pipe, to the right side of the air intake pipe.

[0007] The seat cushion is located above the air intake pipe, and a second baffle is provided below the seat cushion. The second baffle extends from the left side of the air intake pipe to the right side of the air intake pipe, and the side of the second baffle abuts against the first baffle.

[0008] In this embodiment, at least one of the first baffle and the second baffle is an elastomer, and the first baffle and the second baffle are located between the front side of the seat cushion and the air inlet of the air intake pipe.

[0009] In one embodiment, the second baffle includes a connecting portion and a water-blocking portion, the connecting portion being connected to the seat cushion;

[0010] The water-blocking part includes a first water-blocking section, a second water-blocking section, and a third water-blocking section connected in sequence. The first water-blocking section and the third water-blocking section are located on the left and right sides of the air intake pipe, respectively. The second water-blocking section is located at the top of the air intake pipe. The sides of the first water-blocking section, the second water-blocking section, and the third water-blocking section abut against the first baffle plate, respectively.

[0011] In one embodiment, the first baffle is arranged around the intake pipe.

[0012] In one embodiment, the width of the connecting portion is greater than the width of the water-blocking portion.

[0013] In one embodiment, a connecting piece is integrally formed on the underside of the seat cushion, and the connecting part is attached to the connecting piece and fixed to the connecting piece.

[0014] In one embodiment, the connecting piece is provided with a reinforcing rib, and a notch is formed on the connecting part, with the reinforcing rib extending into the notch.

[0015] In one embodiment, the first baffle and the second baffle extend in a vertical direction, respectively.

[0016] In one embodiment, a limiting protrusion is provided on the outer periphery of the intake pipe, and there is a gap between the limiting protrusion and the first baffle along the extension direction of the intake pipe.

[0017] The second baffle extends between the limiting protrusion and the first baffle.

[0018] In one embodiment, two second baffles are provided under the seat cushion, the two second baffles are arranged parallel to each other, and the first baffle is sandwiched between the two second baffles.

[0019] Secondly, embodiments of this application provide a motorcycle including the aforementioned air filter waterproof structure.

[0020] The waterproof air filter structure and motorcycle provided in this application embodiment include a first baffle plate on the outer periphery of the air filter's intake pipe and a second baffle plate located below the seat, abutting against the first baffle plate. Both the first and second baffle plates extend from the left to the right side of the intake pipe, passing over the top of the intake pipe. They are located between the front of the seat and the air inlet of the intake pipe. The front of the seat is connected to the fuel tank. When water seeps into the underside of the seat from between the seat and the fuel tank, the first and second baffle plates prevent water from flowing towards the air inlet of the intake pipe. At least one of the first and second baffle plates is an elastomer; the elastic deformation of the elastomer ensures a tight fit between the first and second baffle plates, guaranteeing their water-blocking effect. In this way, when water seeps into the area under the seat from where it meets the fuel tank, it is less likely to be sucked into the intake manifold, and the air filter is less likely to get wet, thus affecting the normal operation of the engine and ensuring its reliable operation.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] Currently, such as Figures 1-4As shown, the motorcycle includes a main body and a fuel tank 300, a seat 200, and an air filter 100, all mounted on the main body. The air intake pipe 110 of the air filter 100 is located below the seat 200, and the front of the seat 200 connects to the fuel tank 300. Due to the overall layout of the motorcycle and the design limitations of the fuel tank 300, the air intake pipe 110 of the air filter 100 is positioned near the lower part of the area where the seat connects to the fuel tank 300. However, when the user, i.e., the rider, sits on the seat, the downward pressure on the seat can easily cause gaps or poor fit at the joint between the seat and the fuel tank 300. When the user rides the motorcycle in the rain, water on the surface of the fuel tank 300 can be blown down by the wind through the gap between the fuel tank 300 and the seat 200 onto the air intake pipe 110 below the seat 200. Because there is negative pressure near the air intake 111 of the air intake pipe 110, this negative pressure can easily draw water from the air intake pipe 110 into the air filter 100 (for models with larger displacement, the greater the negative pressure at the air intake 111, the easier it is for water to be drawn into the air filter 100), affecting the normal operation of the engine.

[0041] To address the aforementioned problems, this application provides a waterproof air filter structure and a motorcycle. This waterproof air filter structure includes a first baffle plate positioned around the outer periphery of the air filter's intake pipe and a second baffle plate positioned below the seat, abutting against the first baffle plate. Both the first and second baffle plates extend from the left side to the right side of the intake pipe, passing over the top of the intake pipe. The first and second baffle plates are located between the front of the seat and the air inlet of the intake pipe. The front of the seat is connected to the fuel tank. When water seeps into the underside of the seat through the gap between the seat and the fuel tank, the first and second baffle plates prevent the water from flowing towards the air inlet of the intake pipe. At least one of the first and second baffle plates is an elastomer; the elastic deformation of the elastomer ensures a tight fit between the first and second baffle plates, guaranteeing their effectiveness in blocking water. In this way, when water seeps into the area under the seat from where it meets the fuel tank, it is less likely to be sucked into the intake manifold, and the air filter is less likely to get wet, thus affecting the normal operation of the engine and ensuring its reliable operation.

[0042] The following describes in detail the waterproof air filter structure and the technical solution for the motorcycle provided in the embodiments of this application, with reference to the accompanying drawings.

[0043] Reference Figures 5-9 As shown, this application embodiment provides a waterproof air filter structure, including an air filter 100 and a seat 200. The air filter 100 and seat 200 are respectively mounted on the body of the motorcycle. Those skilled in the art will understand that the air filter 100 is connected to the motorcycle's engine and can filter the air entering the engine.

[0044] The air filter 100 is provided with an intake pipe 110, which is located above the body of the air filter 100. The end of the intake pipe 110 away from the body is the air inlet 111. Air can enter the body of the air filter 100 through the intake pipe 110, and after being filtered by the body of the air filter 100, it enters the engine. A first baffle 120 is provided on the outer periphery of the intake pipe 110. The first baffle 120 extends from the left side of the intake pipe 110, through the top of the intake pipe 110, to the right side of the intake pipe 110. The height of the first baffle 120, i.e., the distance between the side of the first baffle 120 away from the intake pipe 110 and the intake pipe 110, is not limited and can be set by those skilled in the art as needed. It is worth mentioning that the first baffle 120 can block water on the air intake pipe 110 to a certain extent, preventing water on the side of the air intake pipe 110 away from the air intake 111 from flowing to the air intake 111 of the air intake pipe 110 under the action of negative pressure.

[0045] The seat cushion 200 is located above the air intake pipe 110, and a second baffle 210 is provided below the seat cushion 200. The second baffle 210 extends from the left side of the air intake pipe 110 to the right side of the air intake pipe 110, and the side of the second baffle 210 abuts against the first baffle 120.

[0046] It is worth mentioning that the front side of the seat 200 is connected to the motorcycle's fuel tank 300. When a user sits on the seat 200, a gap may appear between the front side of the seat 200 and the fuel tank 300 after external force is applied. The second baffle 210 extends downward on the seat 200. The second baffle 210 can be located in front of or behind the first baffle 120. When the second baffle 210 is located in front of the first baffle 120, the rear side of the second baffle 210 abuts against the front side of the first baffle 120; when the second baffle 210 is located behind the first baffle 120, the front side of the second baffle 210 abuts against the rear side of the first baffle 120.

[0047] At least one of the first baffle 120 and the second baffle 210 is an elastic body, and the first baffle 120 and the second baffle 210 are located between the front side of the seat cushion 200 and the air inlet 111 of the air inlet pipe 110.

[0048] Indicatively, when the second baffle 210 abuts against the first baffle 120, the second baffle 210 and the first baffle 120 form a barrier between the air intake pipe 110 and the seat cushion 200, preventing water flowing under the seat cushion 200 from passing over the first baffle 120 and falling to the air intake 111. After the first baffle 120 and the second baffle 210 block the water, the water can slide down through the second baffle 210 and the first baffle 120 to the bottom of the air intake pipe 110.

[0049] For example, only the second baffle 210 is an elastomer, which is fixedly mounted on the seat cushion 200. The first baffle 120 can be integrally molded onto the outer periphery of the air intake pipe 110. In other embodiments, only the first baffle 120 may be an elastomer, or both the first baffle 120 and the second baffle 210 may be elastomers. Exemplarily, at least one of the first baffle 120 and the second baffle 210 may be made of rubber to form an elastomer, which can undergo a certain elastic deformation when subjected to external force. When the seat cushion 200 is subjected to external force, the elastic deformation of the elastomer can ensure that the first baffle 120 and the second baffle 210 reliably abut against each other.

[0050] In addition, at least one of the first baffle 120 and the second baffle 210 is an elastomer, which allows the first baffle 120 and the second baffle 210 to a closer contact, preventing water from seeping into the side of the first baffle 120 facing the air inlet 111 through the space between the first baffle 120 and the second baffle 210.

[0051] Through the cooperation between the first baffle 120 and the second baffle 210, a partition is formed between the front side of the seat cushion 200 and the air inlet 111 of the air intake pipe 110, thereby the first baffle 120 and the second baffle 210 can reliably block water flowing from the gap between the seat cushion 200 and the oil tank 300 to the area below the seat cushion 200 and move to the air inlet 111 of the air intake pipe 110.

[0052] In one possible implementation, the first baffle 120 can be made of metal, and the second baffle 210 can be made of rubber to form an elastomer. A magnetic strip can be embedded at the bottom end of the second baffle 210. When the seat cushion 200 is positioned above the air intake pipe 110 of the air filter 100, the magnetic force between the magnetic strip and the first baffle 120 can reliably abut against the second baffle 210.

[0053] In one embodiment, such as Figures 7-9 As shown, the second baffle 210 includes a connecting portion 211 and a water-retaining portion 212, with the connecting portion 211 connected to the seat cushion 200. Both the connecting portion 211 and the water-retaining portion 212 are sheet-like structures. The connecting portion 211 is located on one side of the water-retaining portion 212 and fixed thereto; both can be located on the same plane. Optionally, the connecting portion 211 and the water-retaining portion 212 can be integrally formed using a molding process. The connecting portion 211 can be fixed to the seat cushion 200 by suitable methods such as fastening with fasteners, bonding, or snap-fit ​​connection; no single method is limited here.

[0054] The water-blocking part 212 includes a first water-blocking section 2121, a second water-blocking section 2122, and a third water-blocking section 2123 connected in sequence. The first water-blocking section 2121 and the third water-blocking section 2123 are located on the left and right sides of the air intake pipe 110, respectively, and the second water-blocking section 2122 is located at the top of the air intake pipe 110. The sides of the first water-blocking section 2121, the second water-blocking section 2122, and the third water-blocking section 2123 abut against the first baffle plate 120.

[0055] Indicative, such as Figure 8 and Figure 9 As shown, the tops of the first water-blocking section 2121, the second water-blocking section 2122, and the third water-blocking section 2123 are respectively connected to the connecting part 211. The first water-blocking section 2121, the second water-blocking section 2122, and the third water-blocking section 2123 form an approximate "U"-shaped structure, with the opening of the "U"-shaped structure facing downwards, and the air intake pipe 110 is inserted into the opening of the "U"-shaped structure. It can be understood that by the first water-blocking section 2121 and the third water-blocking section 2123 cooperating with the first baffle 120, water flow from the left and right sides of the air intake pipe 110 to the air intake port 111 of the air intake pipe 110 can be blocked, and by the second water-blocking section 2122 cooperating with the first baffle 120, water flow from the top of the air intake pipe 110 to the air intake port 111 of the air intake pipe 110 can be blocked.

[0056] With the above settings, the cooperation between the second baffle 210 and the first baffle 120 can effectively block water at the top and left and right sides of the intake pipe 110, further preventing water from moving to the intake port 111 of the intake pipe 110, and further ensuring the reliable operation of the engine.

[0057] In a specific embodiment, such as Figure 5 and Figure 9 As shown, the first baffle 120 is arranged around the intake pipe 110.

[0058] The first baffle 120 is an annular plate structure. Since the first baffle 120 is arranged around the air intake pipe 110, it can effectively block water around the air intake pipe 110. Optionally, the outer circumference of the first baffle 120 can be a suitable shape such as a rectangle or a circle.

[0059] It is worth mentioning that, since the intake pipe 110 is circumferentially equipped with first baffles 120, the first baffles 120 can also effectively block water below the intake pipe 110. When water on the second baffle 210 and / or the first baffle 120 flows downward along the surface of the first baffle 120 to below the intake pipe 110, this part of the water will not flow to the intake port 111 of the intake pipe 110 due to the negative pressure at the intake port 111, further preventing water from flowing to the intake port 111 of the intake pipe 110, thereby ensuring the reliable operation of the engine.

[0060] In one possible implementation, such as Figure 8 and Figure 9 As shown, the width of the connecting part 211 is greater than the width of the water-blocking part 212.

[0061] The width of the connecting portion 211 is its dimension in the left-right direction, and the width of the water-blocking portion 212 is its dimension in the left-right direction. Those skilled in the art can set the width of the connecting portion 211 and the water-blocking portion 212 as needed; no single limitation is made here. In one possible implementation, the left or right end of the connecting portion 211 extends beyond the water-blocking portion 212; in another possible implementation, both the left and right ends of the connecting portion 211 extend beyond the water-blocking portion 212.

[0062] This structure, through the wider connecting portion 211, ensures a reliable connection between the second baffle 210 and the seat 200. A clearance opening is formed between the end of the connecting portion 211 extending beyond the water-blocking portion 212 and the water-blocking portion 212. This clearance opening avoids interference with other parts of the motorcycle, ensuring a reliable fit between the second baffle 210 and the first baffle 120.

[0063] In a specific embodiment, such as Figure 7 and Figure 8 As shown, a connecting piece 220 is integrally formed on the lower part of the cushion 200, and the connecting part 211 is attached to the connecting piece 220 and fixed to the connecting piece 220.

[0064] The connecting piece 220 extends in the same direction as the second baffle 210. For example, the width of the connecting piece 220 is not less than the width of the connecting portion 211. The height of the connecting piece 220 is less than the sum of the height of the second water-blocking section 2122 and the height of the connecting portion 211, to avoid interference between the connecting piece 220 and the air intake pipe 110. The connecting piece 220 can be located on the side of the second baffle 210 facing the first baffle 120 or on the side of the second baffle 210 away from the first baffle 120.

[0065] In one possible implementation, multiple buckles can be spaced out along the left and right direction on the connecting piece 220, and correspondingly, multiple locking holes can be spaced out along the left and right direction on the connecting part 211. The multiple buckles and the multiple locking holes are engaged one-to-one to achieve the fixation between the connecting piece 220 and the connecting part 211.

[0066] By providing a connecting piece 220 below the seat cushion 200, the connecting portion 211 of the second baffle 210 is fixed to the connecting piece 220, thus achieving a reliable connection between the second baffle 210 and the seat cushion 200. When the second baffle 210 is an elastic body, the connecting piece 220 can also provide some support for the second baffle 210, thereby limiting the deformation of the second baffle 210 and ensuring that the second baffle 210 reliably abuts against the first baffle 120.

[0067] In one possible implementation, the connecting piece 220 and the main body of the seat cushion 200 can be connected by a telescopic component, such as a telescopic rod. The height of the second baffle 210 can be adjusted by changing the length of the telescopic component, ensuring reliable contact between the second baffle 210 and the first baffle 120. By providing a telescopic component between the connecting piece 220 and the main body of the seat cushion 200, the height of the second baffle 210 can be adjusted according to the position of the air intake pipe 110 of the air filter 100, improving the versatility of the waterproof structure of the air filter 100.

[0068] In a specific embodiment, such as Figure 8 As shown, the connecting piece 220 has a reinforcing rib 221 protruding from it, and the connecting part 211 has a notch 2111 formed therein, with the reinforcing rib 221 extending into the notch 2111.

[0069] Schematic illustration: Multiple reinforcing ribs 221 can be provided on the two opposite surfaces of the connecting piece 220, and each reinforcing rib 221 can be integrally formed on the connecting piece 220. Along the width direction of the connecting piece 220, the multiple reinforcing ribs 221 can be arranged in parallel at intervals in the middle position of the connecting piece 220. Each reinforcing rib 221 protrudes from the surface of the connecting piece 220.

[0070] The notch 2111 on the connecting part 211 corresponds to the area where the reinforcing rib 221 is arranged on the connecting piece 220. When the connecting part 211 is fixed on the connecting piece 220, the reinforcing rib 221 extends into the notch 2111 to avoid the reinforcing rib 221 affecting the fixation between the connecting piece 220 and the connecting part 211.

[0071] By providing reinforcing ribs 221 on the connecting piece 220, the structural strength of the connecting piece 220 can be improved, ensuring that the position of the second baffle 210 will not shift due to deformation of the connecting piece 220 during long-term use of the motorcycle, thereby ensuring the water-blocking effect of the first baffle 120 and the second baffle 210. Arranging the reinforcing ribs 221 in the middle of the connecting piece 220, and providing notches 2111 at the corresponding positions of the reinforcing ribs 221 in the connecting portion 211, can reduce the impact of the reinforcing ribs 221 on the second baffle 210, allowing the second baffle 210 to reliably abut against the first baffle 120.

[0072] In one embodiment, such as Figures 5-7As shown, the first baffle 120 and the second baffle 210 extend in the vertical direction, respectively.

[0073] For example, the air filter 100 has an air intake pipe 110 with a bend section and a straight section connected in sequence. The air intake port 111 of the air intake pipe 110 is located at the end of the straight section away from the bend section. The first baffle 120 can be set on the straight section.

[0074] Understandably, when the second baffle 210 abuts against the first baffle 120, there is an overlapping area between them. Since at least one of the first baffle 120 and the second baffle 210 is an elastic body, the elastic force of the elastic body allows the first baffle 120 and the second baffle 210 to adhere tightly. When the seat cushion 200 is subjected to an external force and moves up and down, the seat cushion 200 drives the second baffle 210 to move up and down, and during this process, there is always an overlapping area between the second baffle 210 and the first baffle 120, ensuring reliable abutment between them, thereby ensuring the water-blocking effect of the first baffle 120 and the second baffle 210.

[0075] In one possible implementation, when the second baffle 210 includes a first water-blocking section 2121, a second water-blocking section 2122, and a third water-blocking section 2123, the bottom end of the second water-blocking section 2122 abuts against the top of the air inlet pipe 110 of the air filter 100, and the left and right sides of the air inlet pipe 110 abut against the first water-blocking section 2121 and the third water-blocking section 2123, respectively. This arrangement ensures a large overlap area between the second baffle 210 and the first baffle 120, guaranteeing a good seal between them.

[0076] In one embodiment, such as Figure 10 As shown, a limiting protrusion 112 protrudes from the outer periphery of the intake pipe 110, and there is a gap between the limiting protrusion 112 and the first baffle 120 along the extending direction of the intake pipe 110. The second baffle 210 extends into the space between the limiting protrusion 112 and the first baffle 120.

[0077] The limiting protrusion 112 can be located at the top or on the left and right sides of the air intake pipe 110, and the limiting protrusion 112 can be formed on the air intake pipe 110 by an integral molding process. Schematic, the gap between the limiting protrusion 112 and the first baffle 120 matches the thickness of the second baffle 210. By setting the height of the limiting protrusion 112, when the seat cushion 200 moves the second baffle 210 up and down, the end of the second baffle 210 is always located between the limiting protrusion 112 and the first baffle 120.

[0078] In this structure, a limiting protrusion 112 is provided on the air intake pipe 110. The limiting protrusion 112 and the first baffle 120 can limit the second baffle 210, ensuring that the second baffle 210 always abuts against the first baffle 120, thereby ensuring the water-blocking effect of the first baffle 120 and the second baffle 210.

[0079] In one possible implementation, two second baffles 210 are provided under the seat cushion 200, the two second baffles 210 are arranged parallel to each other, and the first baffle 120 is sandwiched between the two second baffles 210.

[0080] Both second baffles 210 can be elastic bodies, and the distance between the two second baffles 210 can be the same as the thickness of the first baffle 120. In one possible implementation, a connecting piece 220 is provided below the seat cushion 200, and the two second baffles 210 are respectively fixed to opposite sides of the connecting piece 220. The thickness of the connecting piece 220 can match the thickness of the first baffle 120.

[0081] By setting two second baffles 210 on the seat cushion 200, and using the two second baffles 210 to clamp the first baffle 120, when the seat cushion 200 moves the second baffles 210, it can be ensured that at least one second baffle 210 abuts against the first baffle 120, thereby reliably ensuring the water-blocking effect of the first baffle 120 and the second baffle 210.

[0082] This application also provides a motorcycle, including the aforementioned waterproof air filter structure. The motorcycle further includes a main body, a fuel tank 300, and an engine. The fuel tank 300, engine, and waterproof air filter structure are respectively mounted on the main body. The front end of the seat 200 of the waterproof air filter structure is connected to the fuel tank 300. The air filter 100 of the waterproof air filter structure can be connected to the engine via a pipeline.

[0083] The motorcycle provided in this application, due to the adoption of the aforementioned air filter waterproof structure, is less likely to be sucked into the air filter 100 when water seeps into the area below the seat 200 from the junction of the seat 200 and the fuel tank 300, thus ensuring the reliable operation of the engine.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
