Description

Technical Field

[0001] The present application relates to the technical field of air filters, and in particular to an air filter device and a motorcycle. Background Art

[0002] At present, motorcycles and other vehicles that use internal combustion engines are usually equipped with air filters to filter impurities in the air entering the engine to ensure the normal operation of the engine. With the development of motorcycle technology, the exhaust volume of vehicle engines is getting larger and larger. Usually, the number of cylinders in the engine is increased to achieve the effect of increasing the exhaust volume. Three-cylinder and four-cylinder models have appeared. As the number of cylinders increases, the exhaust pipe also needs to increase accordingly. The exhaust pipe is usually fixed with other structures on the vehicle (such as throttle body, etc.) through some fixing parts (such as clamps, bolts, etc.), so that the gas treated by the air filter is discharged through the exhaust pipe for the next step of processing.

[0003] In the related art, each air outlet pipe is provided with a corresponding fixing part, and there is no matching relationship between the fixing parts. Therefore, when installing the air outlet pipe, each fixing part needs to be installed and adjusted separately, and the fixing assembly is arranged at a designated installation location to realize the fixed installation of the air outlet pipe.

[0004] However, due to the limited space of vehicles such as motorcycles, the space between various structures is small, and the engine is large and usually installed in the middle of the vehicle, the installation location of the fixed parts is easily blocked by the exhaust pipe, frame, throttle motor and other structures or other exhaust pipes. After the exhaust pipe, frame, throttle motor and other structures are installed in place, it is not easy to adjust the fixed parts. In addition, due to the complex structure of multi-cylinder engines and air filters, it is not easy to modify the internal structure. The method of changing the engine structure to make the installation location of the fixed components in an easy-to-install position is not easy to achieve. Therefore, it is not easy to adjust the fixed parts in actual operation. Summary of the invention

[0005] Based on this, it is necessary to provide an air filter device and a motorcycle to address the problem that the above-mentioned fixed parts are difficult to adjust.

[0032] See also Figure 1 , Figure 1 The front structural schematic diagram of the air filter device in one embodiment of the present application is shown, and the air filter device provided in one embodiment of the present application. The air filter device includes an air filter body 100, a clamp 200 and a connecting assembly 300. Among them, the air filter body 100 includes a plurality of air outlet pipes 110. There are a plurality of clamps 200, and they are sleeved on the outer periphery of the plurality of air outlet pipes 110 in a one-to-one correspondence. The clamp 200 is provided with a through hole 221, and the clamp 200 is provided with a threaded portion (not shown in the figure) or a threaded member 311. The connecting assembly 300 includes a screw 310, and the screw 310 is sequentially penetrated through the through holes 221 of the plurality of clamps 200, and the threaded portions or threaded members 311 of the plurality of clamps 200 are all threadedly connected with the screw 310.

[0033] It should be noted that a gas regulating mechanism is provided inside the air filter body 100 to filter impurities in the air entering the air filter body 100. The air processed by the gas regulating mechanism is discharged from the outlet pipe 110, and the discharged air enters the electronic throttle body 400. The electronic throttle body 400 is connected to the engine. The electronic throttle body 400 is used to adjust the amount of air entering the engine to ensure the combustion efficiency of the fuel and the normal power output of the engine. The above working principle is the prior art and only represents the connection relationship between the various structures, which will not be elaborated here.

[0034] like Figures 1 to 4As shown, preferably, the outlet pipe 110 is arranged on the surface of the air filter body 100, one end of the outlet pipe 110 is located outside the air filter body 100, and is used to connect with the connecting portion of the electronic throttle body 400, so that the outlet pipe 110 is connected with the electronic throttle body 400; the other end of the outlet pipe 110 extends to the inside of the air filter body 100 and is connected with the gas regulating mechanism, and the air processed by the gas regulating mechanism is discharged through the outlet pipe 110. The outlet pipe 110 is sleeved on the outer periphery of the connecting portion of the electronic throttle body 400, and the clamp 200 is sleeved on the outer periphery of the connecting portion of the outlet pipe 110 and the electronic throttle body 400, so that the connecting portion of the outlet pipe 110 and the electronic throttle body 400 is tightly fitted to prevent air leakage. Multiple outlet pipes 110 are arranged side by side away from the end of the air filter body 100, which is easy to be installed in conjunction with the electronic throttle body 400; the number of outlet pipes 110 corresponds to the number of engine cylinders, such as two outlet pipes 110 are corresponding to a two-cylinder engine, and three outlet pipes 110 are corresponding to a three-cylinder engine, to ensure coordination with the engine and normal operation of the engine.

[0035] The screw 310 of the connecting assembly 300 can be inserted into all the through holes 221 in sequence. The screw 310 is threadedly connected to the threaded portion or the threaded member 311 on the clamp 200. By rotating the screw 310, the position of the threaded portion or the threaded member 311 on the screw can be adjusted, thereby adjusting the tightness of the clamp 200 (i.e., adjusting the diameter of the clamp 200) to match the size of the air outlet pipe 110; without adjusting the screw 310, the screw 310 can limit the movement of the threaded portion or the threaded member 311 on the clamp 200, so that after the screw 310 is connected to the clamp 200, the clamp 200 cannot be adjusted, and all clamps 200 can be tightly sleeved on the outer periphery of the air outlet pipe 110.

[0036] When in use, the screw rod 310 is sequentially inserted into the through holes 221 of the plurality of clamps 200 and is threadedly connected with the threaded portion or the threaded member 311 on the clamp 200. The screw rod 310 is adjusted to adjust the clamp 200 to a suitable size and is sleeved on the outer periphery of the outlet pipe 110. Then, the end of the outlet pipe 110 is connected to the connecting portion of the electronic throttle body 400. The screw rod 310 is rotated to adjust the clamp 200 to a suitable tightness to ensure that no leakage occurs at the connection between the outlet pipe 110 and the electronic throttle body 400. At this time, the screw rod 310 restricts the movement of the threaded portion or the threaded member 311 on the clamp 200, so that the clamp 200 is fixed to the outer periphery of the outlet pipe 110, so as to ensure that the outlet pipe 110 is tightly connected to the electronic throttle body 400, and the clamp 200 cannot be adjusted or disassembled. When it is necessary to separate the end of the outlet pipe 110 from the connection portion of the electronic throttle body 400, it is only necessary to adjust the screw 310 again to expand the clamp 200, thereby releasing the restriction of the clamp 200 on the outlet pipe 110 and the electronic throttle body 400, and the end of the outlet pipe 110 can be separated from the connection portion of the electronic throttle body 400.

[0037] In the above structure, the screw rod 310 is threadedly connected with the threaded parts or threaded parts 311 on the multiple clamps 200, so that the multiple clamps 200 can be fastened to the outer periphery of the outlet pipe 110, so that the outlet pipe 110 and the electronic throttle body 400 are tightly connected. In addition, only a small space is required to adjust the tightness of the multiple clamps 200 so that the outlet pipe 110 and the electronic throttle body 400 are connected or separated. The above process is not easily restricted or blocked by the vehicle structure. If there is still blocking, only a small adjustment is required to the structure causing the blocking. By connecting and fixing multiple clamps 200 with a screw rod 310, multiple clamps 200 can be installed and adjusted at the same time, which is simple and quick to operate and can effectively improve the efficiency of disassembly and assembly of the outlet pipe 110.

[0038] In some embodiments, the clamp 200 includes a clamping ring 210 and two connecting seats 220. The clamping ring 210 is sleeved on the outer periphery of the air outlet pipe 110, the connecting seat 220 is arranged on the outer side of the clamping ring 210, the through hole 221 is opened in the connecting seat 220, and the threaded member 311 or the threaded portion is arranged on the connecting seat 220.

[0039] like Figures 1 to 4 As shown, preferably, the clamping ring 210 is a circular ring structure, the connecting seat 220 is fixedly connected to the outer side wall of the clamping ring 210, and the through hole 221 passes through the connecting seat 220. By moving the connecting seat 220, the tightness of the clamping ring 210 can be adjusted (that is, the diameter of the clamping ring 210 can be adjusted). When the clamp 200 is installed, the positions of the connecting seats 220 of multiple clamps 200 are adjusted so that the center points of the through holes 221 of multiple clamps 200 are located on the same straight line, so as to facilitate the installation of the screw 310. The threaded portion or the threaded member 311 is provided on the connecting seat 220, and the connecting seat 220 moves along the screw 310 with the threaded portion or the threaded member 311, thereby the tightness of the clamping ring 210 can be changed by adjusting the screw 310. Through the above structure, when the screw 310 is passed through the through hole 221, the tightness of the clamp 210 can be changed by adjusting the screw 310.

[0040] Furthermore, the thickness of the clamping ring 210 is relatively thin, so that it is easy to deform under the drive of the connecting seat 220 to change the tightness of the clamping ring 210 on the outer periphery of the outlet pipe 110. The threaded portion is arranged in the through hole 221 of the clamp 200, that is, the through hole 221 is a threaded hole, and the screw rod 310 is penetrated in the threaded hole and is threadedly connected with the internal thread in the through hole 221. The position of the connecting seat 220 on the screw rod 310 can be adjusted by rotating the screw rod 310, thereby achieving the above-mentioned technical effect of changing the tightness of the clamping ring 210 by adjusting the screw rod 310. The threaded member 311 can be a nut, and the nut abuts against the side wall of the connecting seat 220. The connecting seat 220 can also be welded with the nut, so that the connecting seat 220 moves with the nut. The position of the nut on the screw rod 310 can be changed by rotating the screw rod 310, thereby adjusting the position of the connecting seat 220 on the screw rod 310, and the above-mentioned technical effect of changing the tightness of the clamping ring 210 by adjusting the screw rod 310 can also be achieved.

[0041] In some embodiments, the snap ring 210 is a non-closed structure, and the two connection seats 220 are respectively disposed at two ends of the snap ring 210 .

[0042] like Figures 1 to 5 As shown, preferably, an opening is provided in the middle of the snap ring 210, so that the snap ring 210 forms a non-closed circular ring structure, and an extension piece 211 is provided at one end of the snap ring 210, one end of the extension piece 211 is fixedly connected to the outer side wall of one end of the snap ring 210, the extension piece 211 covers the opening, and the other end extends to the other end of the snap ring 210. One of the connecting seats 220 is connected to the extension piece 211, and is connected to one end of the snap ring 210 through the extension piece 211. The connecting seat 220 can drive the extension piece 211 to move along the outer wall of the snap ring 210, and the other end of the snap ring 210 moves with the extension piece 211, so as to adjust the diameter of the snap ring 210; another connecting seat 220 is connected to the other end of the snap ring 210. When the screw 310 is threadedly connected with the threaded portion or the threaded member 311, the relative position between the two connecting seats 220 is fixed, thereby achieving the function of fixing the snap ring 210. In addition, a slot may be formed on the outer wall of the snap ring 210 , and the extension piece 211 is snapped into the slot and moves along the slot, so as to prevent the extension piece 211 from being misplaced when moving.

[0043] In some of the embodiments, the connecting assembly 300 also includes a limit sleeve 320, and multiple limit sleeves 320 are arranged corresponding to the clamp 200. The limit sleeve 320 is arranged between the two connecting seats 220 of the clamp 200, and the two ends of the limit sleeve 320 are respectively abutted against the two connecting seats 220, and the screw 310 is passed through the interior of the limit sleeve 320.

[0044] It should be noted that if the clamp 200 is tightened too tightly, the connection between the outlet pipe 110 and the electronic throttle body 400 will be subjected to greater pressure, which may easily cause the connection between the outlet pipe 110 or the electronic throttle body 400 to age or be damaged too quickly; if the clamp 200 is tightened too loosely, the connection between the outlet pipe 110 and the electronic throttle body 400 will not be tight, which may easily cause air leakage. Therefore, the tightness of the clamp 200 should be adjusted to a more appropriate level.

[0045] Due to the above problems, such as Figure 4 and Figure 5 As shown, preferably, the limiting sleeve 320 is a hollow cylindrical structure and is arranged between the two connecting seats 220 of each clamp 200. The tightness of the clamp ring 210 is set by adjusting the relative positions of the two connecting seats 220. When the two connecting seats 220 of the clamp 200 abut against the two ends of the limiting sleeve 320, the clamp ring 210 can be sleeved on the outer periphery of the air outlet pipe 110 with a tightness that is neither too loose nor too tight, so that the user can adjust when installing the clamp 200. When the screw rod 310 is installed, the limiting sleeve 320 is sleeved on the outer periphery of the screw rod 310, and the limiting sleeve 320 is fixed by the connecting seat 220 and the screw rod 310.

[0046] Furthermore, the limiting sleeve 320 can be replaced according to the tightness of the clamp 200. For example, when the distance between the two connecting seats 220 of the clamp 200 is 3 cm, the diameter of the clamp 210 is 20 cm. At this time, the connection between the clamp 210 and the air outlet pipe 110 is neither too loose nor too tight, so the length of the limiting sleeve 320 is selected to be 3 cm. When the two connecting seats 220 of the clamp 200 are respectively abutted against the two ends of the limiting sleeve 320, the clamp 210 can be mounted on the outer periphery of the air outlet pipe 110 with an appropriate tightness, which is convenient for the operator to adjust according to the actual situation and effectively improves the applicability.

[0047] In some of the embodiments, the connecting assembly 300 further includes a bushing 330 , the two ends of which are respectively connected or abutted with two adjacent clamps 200 , the through holes 221 of the adjacent clamps 200 are connected through the bushing 330 , and the screw 310 is passed through the interior of the bushing 330 .

[0048] like Figure 4 and Figure 5 As shown, preferably, the bushing 330 is a hollow cylindrical structure, such as Figure 4As shown, the through holes 221 on the adjacent connecting seats 220 of adjacent clamps 200 are connected through the bushing 330, and the bushing 330 and the connecting seat 220 can be in contact by abutment or detachable connection to fix the relative position of the connecting seats 220 of adjacent clamps 200, and the position of the adjacent connecting seats 220 of adjacent clamps 200 can be pre-adjusted by the bushing 330 so that the through holes 221 of the adjacent clamps 200 are aligned, which is convenient for users to install the screw 310.

[0049] It should be noted that the length of the bushing 330 is selected according to the distance between adjacent clamps 200 after being sleeved on the outer periphery of the outlet pipe 110. For example, after the clamp 200 is correspondingly sleeved on the outlet pipe 110, the clamp 200 is rotated so that the center points of the through holes 221 on the connecting seat 220 are on the same straight line. At this time, the distance between adjacent connecting seats 220 of adjacent clamps 200 is 10 cm, and a bushing 330 with a length of 10 cm can be selected and arranged between adjacent connecting seats 220. The user can easily insert the screw 310 into the through hole 221 and the bushing 330 in turn, making the installation process of the screw 310 more convenient.

[0050] In this application, the threaded member 311 is taken as a nut as an example. Figure 5 As shown, the nut at one end of the screw rod 310 abuts against the outermost clamp 200, and the other end of the screw rod 310 is threadedly connected with the nut, and the nut abuts against the outermost clamp 200 on the other side to limit the movement of the clamp 200 along the length direction of the screw rod 310 and prevent the screw rod 310 from being separated from the through hole 221. The screw rod 310, the nut and the bushing 330 abut against the clamp 200, so that the clamp ring 210 can be fastened to the outer periphery of the outlet pipe 110. The above method only needs to set one nut (that is, one threaded member 311), and the clamp 200 can be squeezed by the nut and the nut of the screw rod 310. The distance between adjacent clamps 200 is limited by the bushing 330. In the process of reducing the distance between the nut and the nut, all the clamps 200 are squeezed by the nut, the bushing and the nut, so as to be tightened; when the nut is away from the nut, the clamp 200 is not squeezed, so as to be relaxed. The above method is only one of the preferred embodiments, not the only setting method, and is only used to illustrate the principle without limiting the solution.

[0051] In some embodiments, the material of the air outlet pipe 110 is rubber material.

[0052] Preferably, the outlet pipe 110 is made of a soft rubber material. When the clamp 200 is sleeved on the outer periphery of the outlet pipe 110, the tightness of the clamp 200 can be adjusted to squeeze the outlet pipe 110 so that the outlet pipe 110 is slightly deformed, thereby ensuring that the outlet pipe 110 can fit tightly with the connecting part of the electronic throttle body 400, thereby avoiding air leakage between the connecting part of the outlet pipe 110 and the electronic throttle body 400.

[0053] In some embodiments, a first positioning structure (not shown in the figure) is provided at a corresponding position on the outer wall of the plurality of air outlet pipes 110, and a second positioning structure (not shown in the figure) is provided on the inner surface of the clamp 200, and the first positioning structure is in contact with the second positioning structure.

[0054] Preferably, the first positioning structure can be set as a groove, and the second positioning structure corresponding to the first positioning structure can be set as a convex block, and the convex block can be clamped in the groove. When the second positioning structure (convex block) on the clamp 200 is clamped with the first positioning structure (groove) on the outer wall of the outlet pipe 110, the clamp 200 cannot rotate relative to the outlet pipe 110. Since multiple clamps 200 have the same structure, the positional relationship between the connecting seat 220 of the clamp 200 and the second positioning structure is the same.

[0055] Furthermore, the groove is arranged on the outlet pipe 110, and the first positioning structures of the plurality of outlet pipes 110 are all located at the same position; the second positioning structures of the plurality of clamps 200 are also all located at the same position, and the position of the connecting seat 220 corresponds to the second positioning structure. Through the above arrangement, when the first positioning structure contacts the second positioning structure, the through holes 221 of all the clamps 200 can be arranged correspondingly. For example, the first positioning structures are all located directly above the center point of the cross section of the air outlet pipe 110, the second positioning structures are all located directly above the center point of the clamp 200, and the connecting seats 220 are all located directly below the center point of the clamp 200. When installing the clamp 200, the second positioning structure is set corresponding to the first positioning structure, and the clamp 200 is sleeved on the outer periphery of the air outlet pipe 110. At this time, the first positioning structure and the second positioning structure are not in contact. Subsequently, the tightness of the clamp 200 is adjusted so that the clamp 200 squeezes the air outlet pipe 110. The second positioning structure contacts the first positioning structure so that the clamp 200 cannot rotate relative to the air outlet pipe 110. At this time, the connecting seats 220 of all the clamps 200 are located directly below the center point of the clamp 200. Since the structures of the clamps 200 are the same, the center points of all the through holes 221 are located on the same straight line, which is convenient for the subsequent installation of the screw 310.

[0056] Through the above structure, when installing the clamp 200, it is only necessary to set the first positioning structure and the second positioning structure correspondingly to achieve the correspondence between the through holes 221 of all the clamps 200, which is convenient for the subsequent installation operation of the screw 310. There is no need to manually adjust the installation position of the clamp 200, which effectively improves the installation accuracy and efficiency of the clamp 200.
