Description

TECHNICAL FIELD

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

[0002] At present, vehicles such as motorcycles using internal combustion engines to do work are usually provided with air filters to filter impurities in the air entering the engine to ensure normal operation of the engine. With the development of motorcycle technology, the displacement of vehicle engines is getting larger and larger, and the displacement is usually increased by increasing the number of cylinders of the engine. Three-cylinder and four-cylinder models have appeared. Due to the increase in the number of cylinders, the exhaust pipe also needs to increase the number of cylinders. The exhaust pipe is usually fixed to other structures on the vehicle (such as the throttle body) by some fixing parts (such as clamps, bolts, etc.) to allow the gas treated by the air filter to be discharged through the exhaust pipe for further treatment.

[0003] In the related art, one fixing part is provided for each exhaust pipe, and there is no cooperation relationship between the fixing parts. Therefore, when installing the exhaust pipes, each fixing part needs to be installed and adjusted separately. The fixing assembly is arranged at a specified installation position to achieve the fixed installation of the exhaust pipe.

[0004] However, due to the limited space of vehicles such as motorcycles, the space between structures is small, and the engine body is usually arranged at the middle position of the vehicle. The installation position of the fixing part is easily blocked by the exhaust pipe, the frame, the throttle motor and other structures or other exhaust pipes. After the exhaust pipe, the frame, the throttle motor and other structures are installed in place, it is not easy to adjust the fixing part. In addition, due to the complex structure of multi-cylinder engines and air filters, it is not easy to modify the internal structure. It is not easy to achieve the method of changing the engine structure to make the installation position of the fixing assembly easy to install. Therefore, it is not easy to adjust the fixing part in actual operation. CONTENT OF THE UTILITY MODEL

[0032] Referring to Figure 1 , Figure 1 A front structure schematic diagram of an air filter device in an embodiment of the present application is shown, and the air filter device provided by the embodiment of the present application. The air filter device includes an air filter body 100, a clamp 200 and a connecting assembly 300. The air filter body 100 includes a plurality of air outlet pipes 110. The clamp 200 is provided with a plurality of and is correspondingly sleeved on the outer periphery of the plurality of air outlet pipes 110. The clamp 200 is provided with a threaded portion (not shown in the figure) or a threaded part 311. The connecting assembly 300 includes a threaded rod 310, which is sequentially threaded through the through holes 221 of the plurality of clamps 200. The threaded portions or threaded parts 311 of the plurality of clamps 200 are all threadedly connected with the threaded rod 310.

[0033] It should be noted that the inside of the air filter body 100 is provided with a gas adjusting mechanism to filter impurities in the air entering the air filter body 100. The air treated by the gas adjusting mechanism is discharged from the air outlet pipe 110, and the discharged air enters the electronic throttle body 400. The electronic throttle body 400 is connected with the engine, and 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 prior art, only indicating the connection relationship between the structures, and will not be described in detail here.

[0034] As Figures 1 to 4As shown, preferably, the air outlet pipe 110 is arranged on the surface of the air filter main body 100, one end of the air outlet pipe 110 is located outside the air filter main body 100, and is connected with the connecting part of the electronic throttle body 400 to make the air outlet pipe 110 communicate with the electronic throttle body 400; the other end of the air outlet pipe 110 extends to the inside of the air filter main body 100 and communicates with the gas adjusting mechanism, and the air treated by the gas adjusting mechanism is discharged through the air outlet pipe 110. The air outlet pipe 110 is sleeved on the outer periphery of the connecting part of the electronic throttle body 400, the clamp 200 is sleeved on the outer periphery of the connecting part of the air outlet pipe 110 and the electronic throttle body 400, so that the air outlet pipe 110 is tightly fitted with the connecting part of the electronic throttle body 400 to prevent air leakage. The ends of the plurality of air outlet pipes 110 away from the air filter main body 100 are arranged side by side, which is easy to cooperate with the electronic throttle body 400 for installation; the number of the air outlet pipes 110 corresponds to the number of cylinders of the engine, for example, two air outlet pipes 110 are arranged for a two-cylinder engine, and three air outlet pipes 110 are arranged for a three-cylinder engine, so as to ensure cooperation with the engine and make the engine work normally.

[0035] The screw rod 310 of the connecting assembly 300 can be sequentially arranged in all the through holes 221, and the screw rod 310 is threadedly connected with the threaded part or the threaded part 311 on the clamp 200, so that the position of the threaded part or the threaded part 311 on the screw rod 310 can be adjusted by rotating the screw rod 310, 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 rod 310, the screw rod 310 can limit the movement of the threaded part or the threaded part 311 on the clamp 200, so that after the screw rod 310 is connected with the clamp 200, the clamp 200 cannot be adjusted, and all the clamps 200 can be tightly sleeved on the outer periphery of the air outlet pipe 110.

[0036] In use, the screw rod 310 is sequentially arranged in the through holes 221 of the plurality of clamps 200 and is threadedly connected with the threaded part or the threaded part 311 on the clamp 200, the clamp 200 is adjusted to a suitable size by adjusting the screw rod 310, and is sleeved on the outer periphery of the air outlet pipe 110, and then the end of the air outlet pipe 110 is connected with the connecting part of the electronic throttle body 400, the clamp 200 is adjusted to a suitable tightness by rotating the screw rod 310, and it is ensured that the connection between the air outlet pipe 110 and the electronic throttle body 400 does not leak. At this time, the screw rod 310 limits the movement of the threaded part or the threaded part 311 on the clamp 200, so that the clamp 200 is fixed on the outer periphery of the air outlet pipe 110 to ensure that the air outlet pipe 110 is tightly connected with the electronic throttle body 400, and the clamp 200 cannot be adjusted or disassembled. When it is necessary to separate the end of the air outlet pipe 110 from the connecting part of the electronic throttle body 400, the clamp 200 is expanded by adjusting the screw rod 310 again, so that the clamp 200 is released from the air outlet pipe 110 and the electronic throttle body 400, and then the end of the air outlet pipe 110 can be separated from the connecting part of the electronic throttle body 400.

[0037] In the above structure, the plurality of clamps 200 are fastened to the outer periphery of the air outlet pipe 110 through the threaded connection of the screw 310 and the threaded part or threaded member 311 on the plurality of clamps 200, so that the air 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 plurality of clamps 200 to connect or separate the air outlet pipe 110 and the electronic throttle body 400, and the above process is not easily limited and blocked by the structure of the vehicle. If there is still blocking, only a small adjustment of the structure causing the blocking is required. Through the connection and fixation of the plurality of clamps 200 by the screw 310, the plurality of clamps 200 can be simultaneously installed and adjusted, which is simple and fast, and can effectively improve the disassembly efficiency of the air 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 arranged in the connecting seat 220, and the threaded part or threaded member 311 is arranged in the connecting seat 220.

[0039] As shown in Figures 1 to 4 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, the through hole 221 penetrates the connecting seat 220, and the tightness of the clamping ring 210 can be adjusted (i.e. the diameter of the clamping ring 210 can be adjusted) by moving the connecting seat 220. When the clamp 200 is installed, the positions of the connecting seats 220 of the plurality of clamps 200 are adjusted, so that the center points of the through holes 221 of the plurality of clamps 200 are located on the same straight line, so as to facilitate the installation of the screw 310. The threaded part or threaded member 311 is arranged in the connecting seat 220, and the connecting seat 220 moves along the screw 310 with the threaded part or threaded member 311, so that the tightness of the clamping ring 210 can be changed by adjusting the screw 310. Through the above structure, when the screw 310 is arranged in the through hole 221, the tightness of the clamping ring 210 can be changed by adjusting the screw 310.

[0040] Furthermore, the thinner thickness of the retaining ring 210 facilitates deformation under the influence of the connecting seat 220, thereby changing the tightness of the retaining ring 210 around the vent pipe 110. The threaded portion is located within the through hole 221 of the clamp 200, meaning the through hole 221 is a threaded hole. The screw 310 passes through the threaded hole and is threadedly connected to the internal thread within the through hole 221. Rotating the screw 310 adjusts the position of the connecting seat 220 on the screw 310, thus achieving the aforementioned effect of changing the tightness of the retaining ring 210 by adjusting the screw 310. The threaded component 311 can be a nut, which abuts against the side wall of the connecting seat 220. The connecting seat 220 can also be welded to the nut, allowing the connecting seat 220 to move with the nut. Rotating the screw 310 changes the position of the nut on the screw 310, thereby adjusting the position of the connecting seat 220 on the screw 310, also achieving the aforementioned effect of changing the tightness of the retaining ring 210 by adjusting the screw 310.

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

[0042] like Figures 1 to 5 As shown, preferably, the retaining ring 210 has an opening in the middle, forming a non-closed circular structure. One end of the retaining ring 210 has an extension 211, one end of which is fixedly connected to the outer wall of one end of the retaining ring 210, covering the opening, and the other end extends to the other end of the retaining ring 210. One connecting seat 220 is connected to the extension 211 and to one end of the retaining ring 210 through the extension 211. The connecting seat 220 can drive the extension 211 to move along the outer wall of the retaining ring 210, and the other end of the retaining ring 210 moves with the extension 211, thereby adjusting the diameter of the retaining ring 210. The other connecting seat 220 is connected to the other end of the retaining ring 210. When the screw 310 is threadedly connected to the threaded part or the threaded component 311, the relative position between the two connecting seats 220 is fixed, thereby achieving the function of fixing the retaining ring 210. In addition, a groove can be opened on the outer wall of the retaining ring 210, and the extension 211 is engaged in the groove and moves along the groove to avoid misalignment when the extension 211 moves.

[0043] In some embodiments, the connecting assembly 300 further includes a limiting sleeve 320, with multiple limiting sleeves 320 corresponding to the clamps 200. The limiting sleeves 320 are located between two connecting seats 220 of the clamps 200, with both ends of the limiting sleeves 320 abutting against the two connecting seats 220 respectively. The screw 310 passes through the interior of the limiting sleeves 320.

[0044] It should be noted that, since the clamps 200 are fastened too tightly, the connecting part of the air outlet pipe 110 and the electronic throttle body 400 will be subjected to a large pressure, which will easily cause the connecting part of the air outlet pipe 110 or the electronic throttle body 400 to age or be damaged too quickly; if the clamps 200 are fastened too loosely, the connecting part of the air outlet pipe 110 and the electronic throttle body 400 will not be connected tightly, which will easily cause air leakage, therefore, the tightness of the clamps 200 should be adjusted to a more appropriate level.

[0045] Due to the above problems, as shown in Figure 4 and Figure 5 , 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 clasp 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 the two ends of the limiting sleeve 320, the clasp 210 can be sleeved on the outer periphery of the air outlet pipe 110 at a tightness that is neither too loose nor too tight, so as to facilitate the user to adjust the clamp 200 during installation. 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] Further, 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 and the diameter of the clasp 210 is 20 cm, at this time, the connection between the clasp 210 and the air outlet pipe 110 is neither too loose nor too tight, then the length of the limiting sleeve 320 is selected to be 3 cm, when the two connecting seats 220 of the clamp 200 abut the two ends of the limiting sleeve 320 respectively, the clasp 210 can be sleeved on the outer periphery of the air outlet pipe 110 at a suitable tightness, which facilitates the operator to adjust according to the actual situation and effectively improves the applicability.

[0047] In some embodiments, the connecting assembly 300 further comprises a bushing 330, both ends of the bushing 330 are connected or abutted with the adjacent two clamps 200, the through holes 221 of the adjacent clamps 200 are communicated through the bushing 330, and the screw rod 310 is arranged in the inside of the bushing 330.

[0048] As shown in Figure 4 and Figure 5 , preferably, the bushing 330 is a hollow cylindrical structure, as shown in Figure 4As shown, the through holes 221 on the adjacent connecting seats 220 of the adjacent clamps 200 are communicated through the bushings 330, which are in contact with the connecting seats 220 through abutting or detachable connection, so as to fix the relative positions of the connecting seats 220 of the adjacent clamps 200 and pre-adjust the positions of the adjacent connecting seats 220 of the adjacent clamps 200 through the bushings 330, so that the through holes 221 of the adjacent clamps 200 are aligned, facilitating the installation of the threaded rods 310 by the user.

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

[0050] In this application, the threaded part 311 is taken as a nut as an example. As shown, Figure 5 The nut is in abutment with the clamp 200 located at the other side of the outermost side, so as to limit the movement of the clamps 200 along the length direction of the threaded rod 310, avoiding the threaded rod 310 from being separated from the through holes 221. The abutment of the threaded rod 310, the nut and the bushing 330 with the clamps 200 can make the clamps 210 fastened to the outer periphery of the air outlet pipe 110. The above method only needs to arrange one nut (i.e. the threaded part 311 is one), which can press the clamps 200 through the nut and the screw cap, and the distance between the adjacent clamps 200 is limited by the bushing 330. In the process of reducing the distance between the nut and the screw cap, all the clamps 200 will be pressed by the screw cap, the bushing and the nut, so as to be tightened. When the nut is away from the screw cap, the clamps 200 are not pressed, so as to be loosened. The above method is only one preferred embodiment, and is not the only arrangement, which is only used to illustrate the principle and does not limit the scheme.

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

[0052] Preferably, the air outlet pipe 110 is made of soft rubber material. When the clamps 200 are sleeved on the outer periphery of the air outlet pipe 110, the tightness of the clamps 200 can be adjusted to press the air outlet pipe 110 to slightly deform the air outlet pipe 110, so as to ensure that the air outlet pipe 110 can be closely fitted with the connecting part of the electronic throttle body 400, avoiding the air leakage between the air outlet pipe 110 and the connecting part of the electronic throttle body 400.

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

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

[0055] Further, the groove is provided on the air outlet pipe 110, and the first positioning structure of the plurality of air outlet pipes 110 is located at the same position; the second positioning structure of the plurality of clamps 200 is also located at the same position, and the position of the connecting seat 220 corresponds to the second positioning structure. Through the above setting, when the first positioning structure is in contact with the second positioning structure, the through holes 221 of all the clamps 200 can be correspondingly arranged. For example, the first positioning structure is located directly above the center point of the cross section of the air outlet pipe 110, the second positioning structure is located directly above the center point of the clamp 200, and the connecting seat 220 is located directly below the center point of the clamp 200. When installing the clamp 200, the second positioning structure is correspondingly arranged with 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 is not in contact with the second positioning structure, then the tightness of the clamp 200 is adjusted to make the clamp 200 extrude the air outlet pipe 110, the second positioning structure is in contact with the first positioning structure to make the clamp 200 unable to rotate relative to the air outlet pipe 110, at this time the connecting seat 220 of all the clamps 200 is located directly below the center point of the clamp 200, since the structure of the clamp 200 is the same, the center points of all the through holes 221 are located on the same straight line, which is convenient for subsequent installation of the screw rod 310.

[0056] Through the above structure, when installing the clamp 200, only the first positioning structure and the second positioning structure need to be correspondingly arranged, so that the through holes 221 of all the clamps 200 can be correspondingly arranged, which is convenient for subsequent installation operation of the screw rod 310, and there is no need for artificial adjustment of the installation position of the clamp 200, thereby effectively improving the installation precision and installation efficiency of the clamp 200.

[0057] In some embodiments, the outer surface of the air outlet pipe 110 is provided with a limiting groove 111, and the clamp 200 is arranged in the limiting groove 111.
