Description

Technical Field

[0001] This utility model belongs to the field of air filter technology and relates to an air filter for electric motorcycles. Background Technology

[0002] In the electric motorcycle industry, air filters are crucial for ensuring the normal operation of vehicles. Traditional air filters often lack adjustment space during installation, making them prone to interference with the main vehicle components during assembly. Inaccurate positioning or insecure fixing can lead to movement or gaps, allowing unfiltered air to directly enter the system, severely impacting filtration efficiency. Furthermore, the structural strength of the components is insufficient, making them susceptible to deformation after external impacts or prolonged use. In addition, disassembly requires various tools, making the process cumbersome and inconvenient for cleaning and replacing the filter plate, increasing maintenance costs and difficulty.

[0003] Therefore, we propose an air filter for electric motorcycles that is flexible to install, highly efficient in filtration, structurally stable, not easily deformed or develops gaps due to external forces or long-term use, and is easy to maintain, clean, and has a long service life. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an air filter for electric motorcycles. The technical problem to be solved by this utility model is: how to achieve flexible installation, high filtration efficiency, stable structure, resistance to deformation and gaps caused by external forces or long-term use, convenient maintenance, easy cleaning, and long service life of the air filter.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An air filter for an electric motorcycle includes a housing, a filter plate, and a mounting base. The filter plate is disposed inside the housing. The housing has an air inlet and an air outlet. The mounting base is fixed to the upper end of the housing and has an elliptical mounting through hole.

[0007] The outer casing includes a shell, a cover, and a connecting opening ring. The cover is located on the side of the shell away from the vehicle body. The filter plate is located between the shell and the cover. An air outlet is provided on the side wall of the shell, and an air inlet is provided on the cover. The mounting base is fixed to the upper end of the shell. Several connecting ears 1 are fixed on the side wall of the shell, and several connecting ears 2 are fixed on the side wall of the cover. The number and position of the connecting ears 2 correspond to the connecting ears 1. A fixing groove is provided on the end face of the connecting ear 1 away from the connecting ear 2. A limiting groove is provided on the end face of the connecting ear 2 away from the connecting ear 1. A stop block is fixed on the groove wall of the fixing groove. A fixing rubber sleeve is fitted on one end of the connecting opening ring, and a limiting rubber sleeve is fitted on the other end of the connecting opening ring. The fixing rubber sleeve is located inside the fixing groove, and the limiting rubber sleeve is located inside the limiting groove.

[0008] The working principle of this utility model is as follows: During operation, air enters through the air inlet on the shell cover, is filtered by the filter plate located between the shell and the shell cover, and the filtered air is discharged through the air outlet on the side wall of the shell. The mounting base is fixed to the upper end of the shell, and the elliptical mounting through hole on it facilitates the installation of the air filter. The shell and the shell cover are connected by connecting lug one and connecting lug two. The filter plate is clamped between the shell and the shell cover. The fixing rubber sleeve at one end of the connecting opening ring is installed in the fixing groove under the action of the stop block, and the limiting rubber sleeve at the other end is in the limiting groove, realizing the fixed connection between the shell and the shell cover. When it is necessary to open the shell, push the connecting opening ring onto the end with the limiting rubber sleeve, so that the limiting rubber sleeve deforms and comes out from the limiting groove, thereby detaching the connection between the shell and the shell cover, opening the shell, and cleaning the filter plate and the inside of the shell.

[0009] A retaining ring is fixed to one end of the housing facing the filter plate. The shape and size of the retaining ring are matched with the filter plate. The filter plate is located inside the retaining ring. A pressure ring is fixed to one end of the housing cover facing the filter plate. The shape and size of the pressure ring are matched with the filter plate. The pressure ring is located inside the retaining ring, and the end face of the pressure ring abuts against the filter plate.

[0010] With the above structure, the filter plate is positioned and partially limited by the retaining ring, and the pressure ring further presses down on the filter plate, so that the filter plate is firmly fixed between the shell and the cover. This ensures that during the air filtration process, air can only be filtered through the filter plate, preventing the filter plate from moving or gaps from causing unfiltered air to pass through.

[0011] The side wall of the housing is provided with a reinforcing groove, and the end of the housing near the vehicle body is provided with an avoidance groove.

[0012] By adopting the above structure, the structural strength of the shell is changed by strengthening the groove, which enhances the rigidity of the shell and prevents it from deforming due to external forces during use. At the same time, the clearance groove is used to avoid certain parts on the vehicle body during installation, ensuring that the air filter can be installed smoothly on the electric motorcycle without interfering with the vehicle body.

[0013] The end of the cover away from the housing has several evenly distributed hemispherical grooves, and a baffle is fixed on the end of the cover away from the housing, with the baffle located above and to the side of the air inlet.

[0014] With the above structure, the hemispherical groove can change the direction and speed of air flow to a certain extent during vehicle operation, playing a preliminary buffering and turbulence role, while enhancing aesthetics and visual appeal. The baffle is located above and to the side of the air intake to prevent foreign objects from directly entering the air intake, playing a blocking and protective role, ensuring that the air entering the air intake is relatively pure, and reducing damage to the filter plate.

[0015] The filter plate has a pressed groove, which is X-shaped, and a number of filter holes are evenly distributed in a rectangular array on the filter plate.

[0016] With the above structure, after air enters the housing through the air inlet, it first comes into contact with the filter plate. The X-shaped molding groove can increase the structural strength of the filter plate, prevent it from deforming during use, and ensure that the shape and spacing of the filter holes remain stable. When the air passes through the filter plate, impurities are intercepted, and the air passes through the filter holes, thereby achieving air filtration. The filtered air is discharged from the air outlet.

[0017] Compared with existing technologies, this air filter for electric motorcycles has the following advantages:

[0018] 1. By setting up mounting through holes and avoidance grooves, the elliptical mounting through holes provide a certain adjustment space for installation, which can better adapt to the needs of different installation positions and improve installation flexibility; the avoidance grooves can accurately avoid vehicle parts, ensuring that the filter can be installed smoothly and avoiding interference with the vehicle body, which greatly improves the convenience of installation and the compatibility with the vehicle.

[0019] 2. By using the combination of the retaining ring and the pressure ring, the filter plate is positioned and pressed, effectively preventing it from moving or developing gaps. This ensures that all air must pass through the filter plate, eliminating the possibility of unfiltered air passing directly and significantly improving filtration efficiency.

[0020] 3. By setting reinforcing grooves and pressing grooves and optimizing the structural shape, the rigidity and deformation resistance of the shell and filter plate are enhanced respectively, making the shell and filter plate less susceptible to damage when subjected to external impact and extending their service life.

[0021] 4. The connection of connecting ear one, connecting ear two, connecting opening ring, fixing rubber sleeve and limiting rubber sleeve makes the disassembly of the shell and the shell cover simple. Just push the connecting opening ring to make the limiting rubber sleeve come out of the limiting groove, and the shell can be opened to clean or replace the filter plate and its interior without complicated tools, which greatly reduces the difficulty and cost of maintenance.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1-6 As shown, the air filter for this electric motorcycle includes a housing 1, a filter plate 2, and a mounting base 5. The filter plate 2 is disposed inside the housing 1. The housing 1 has an air inlet 3 and an air outlet 4. The mounting base 5 is fixed to the upper end of the housing 1. The mounting base 5 has an elliptical mounting through hole 6.

[0031] The outer casing 1 includes a housing 7, a cover 8, and a connecting opening ring 14. The cover 8 is located on the side of the housing 7 away from the vehicle body. The filter plate 2 is located between the housing 7 and the cover 8. An air outlet 4 is provided on the side wall of the housing 7, and an air inlet 3 is provided on the cover 8. The mounting base 5 is fixed to the upper end of the housing 7. Several connecting ears 9 are fixed on the side wall of the housing 7, and several connecting ears 10 are fixed on the side wall of the cover 8. The number and position of the connecting ears 10 correspond to the connecting ears 9. A fixing groove 11 is provided on the end face of the connecting ear 9 away from the connecting ear 10, and a limiting groove 13 is provided on the end face of the connecting ear 10 away from the connecting ear 9. A stop block 12 is fixed on the groove wall of the fixing groove 11. A fixing rubber sleeve 15 is fitted on one end of the connecting opening ring 14, and a limiting rubber sleeve 16 is fitted on the other end of the connecting opening ring 14. The fixing rubber sleeve 15 is located inside the fixing groove 11, and the limiting rubber sleeve 16 is located inside the limiting groove 13.

[0032] In this embodiment, during operation, air enters through the air inlet 3 on the cover 8, is filtered by the filter plate 2 located between the housing 7 and the cover 8, and the filtered air is discharged through the air outlet 4 on the side wall of the housing 7. The mounting base 5 is fixed to the upper end of the housing 7, and the elliptical mounting through hole 6 on it facilitates the installation of the air filter. The housing 7 and the cover 8 are connected by connecting lug 1 9 and connecting lug 2 10. The filter plate 2 is clamped between the housing 7 and the cover 8. The fixing rubber sleeve 15 at one end of the connecting opening ring 14 is installed in the fixing groove 11 under the action of the stop block 12, and the limiting rubber sleeve 16 at the other end is in the limiting groove 13, realizing the fixed connection between the housing 7 and the cover 8. When it is necessary to open the outer shell 1, push the connecting opening ring 14 to fit one end of the limiting rubber sleeve 16, so that the limiting rubber sleeve 16 deforms and comes out from the inside of the limiting groove 13, thereby detaching the connection between the housing 7 and the cover 8, opening the outer shell 1, and cleaning the filter plate 2 and the inside of the outer shell 1.

[0033] A retaining ring 17 is fixed on one end of the housing 7 facing the filter plate 2. The shape and size of the retaining ring 17 are matched and correspond to the filter plate 2. The filter plate 2 is located inside the retaining ring 17. A pressure ring 18 is fixed on one end of the housing cover 8 facing the filter plate 2. The shape and size of the pressure ring 18 are matched and correspond to the filter plate 2. The pressure ring 18 is located inside the retaining ring 17, and the end face of the pressure ring 18 abuts against the filter plate 2.

[0034] In this embodiment, the filter plate 2 is positioned and partially limited by the enclosure ring 17, and the pressure ring 18 further presses down on the filter plate 2, so that the filter plate 2 is firmly fixed between the housing 7 and the cover 8, ensuring that air can only be filtered through the filter plate 2 during the air filtration process, and preventing the filter plate 2 from moving or having gaps that would allow unfiltered air to pass through.

[0035] A reinforcing groove 19 is provided on the side wall of the housing 7, and an avoidance groove 20 is provided on the end of the housing 7 near the vehicle body.

[0036] In this embodiment, the structural strength of the housing 7 is changed by reinforcing the groove 19, thereby enhancing the rigidity of the housing 7 and preventing it from deforming due to external forces during use. At the same time, the avoidance groove 20 is used to avoid certain components on the vehicle body during installation, ensuring that the air filter can be smoothly installed on the electric motorcycle and avoiding interference with the vehicle body.

[0037] The end of the cover 8 away from the housing 7 has several evenly distributed hemispherical grooves 21, and a baffle 22 is fixed on the end of the cover 8 away from the housing 7. The baffle 22 is located above and to the side of the air inlet 3.

[0038] In this embodiment, during vehicle operation, the hemispherical groove 21 can change the airflow direction and speed to a certain extent, playing a preliminary buffering and turbulence role, while enhancing aesthetics and visual appeal. The baffle 22 is located above and to the side of the air intake 3, preventing foreign objects from directly entering the air intake 3, playing a blocking and protective role, ensuring that the air entering the air intake 3 is relatively pure, and reducing damage to the filter plate 2.

[0039] The filter plate 2 has a pressed groove 23, which is X-shaped, and the filter plate 2 has a number of rectangular arrays of filter holes 24.

[0040] In this embodiment, after air enters the housing 1 through the air inlet 3, it first contacts the filter plate 2. The X-shaped molding groove 23 can increase the structural strength of the filter plate 2, prevent it from deforming during use, and ensure that the shape and spacing of the filter holes 24 remain stable. When the air passes through the filter plate 2, impurities are intercepted, and the air passes through the filter holes 24, thereby achieving air filtration. The filtered air is discharged from the air outlet 4.

[0041] The working principle of this utility model is as follows: When in use, the entire air filter is first stably installed in the corresponding position of the electric motorcycle through the elliptical mounting through hole 6 opened on the mounting base 5. The avoidance groove 20 opened on the housing 7 can accurately avoid some parts on the vehicle body, effectively preventing interference during installation. The reinforcing groove 19 opened on the side wall of the housing 7 significantly enhances the overall rigidity and structural strength of the housing 7 by changing the structural shape of the housing 7, and avoids deformation of the housing 7.

[0042] When the air filter starts working, the baffle 22 fixed on the cover 8 can effectively block dust, debris and other foreign objects from directly entering the air inlet 3, providing initial protection for the incoming air and reducing the filtration burden on the subsequent filter plate 2.

[0043] After air enters the interior of the housing 1 through the air inlet 3, it flows to the filter plate 2, the retaining ring 17 and the pressure ring 18, which firmly clamp the filter plate 2 between the housing 7 and the cover 8, effectively preventing the filter plate 2 from moving or developing gaps during air flow or vehicle driving bumps, ensuring that all incoming air must be filtered by the filter plate 2.

[0044] The X-shaped compression grooves 23 on the filter plate 2 greatly enhance the structural strength of the filter plate 2 itself, preventing it from deforming due to force during use. This ensures that the shape and spacing of the several rectangular array of filter holes 24 on the filter plate 2 remain stable. When air flows through the filter plate 2, fine impurities in the air will be intercepted by the filter holes 24, achieving efficient air filtration.

[0045] Finally, the clean air filtered by the filter plate 2 will be discharged from the air outlet 4 opened on the side wall of the housing 7 and enter the relevant components of the electric motorcycle, providing a clean air environment for the normal operation of the vehicle. In addition, the connection between the housing 7 and the cover 8 is achieved through connecting ear 1 9 and connecting ear 2 10. The fixing rubber sleeve 15 and limiting rubber sleeve 16 at both ends of the connecting opening ring 14 are located in the fixing groove 11 of connecting ear 1 9 and the limiting groove 13 of connecting ear 2 10, respectively, ensuring the overall stability of the housing 1. When it is necessary to clean the filter plate 2 or the inside of the housing 1, simply push the connecting opening ring 14 to make the limiting rubber sleeve 16 disengage from the limiting groove 13, and the housing 1 can be opened, which is convenient.

[0046] In summary, by setting the mounting through hole 6 and the avoidance groove 20, the elliptical mounting through hole 6 provides a certain adjustment space for installation, which can better adapt to the needs of different installation positions and improve installation flexibility; the avoidance groove 20 can accurately avoid vehicle parts, ensuring that the filter can be installed smoothly and avoiding interference with the vehicle body, which greatly improves the convenience of installation and the compatibility with the vehicle.

[0047] By using the enclosure ring 17 and the pressure ring 18 together, the filter plate 2 is positioned and pressed, effectively preventing it from moving or having gaps, ensuring that all air must pass through the filter plate 2, eliminating the situation where unfiltered air passes directly, and significantly improving filtration efficiency.

[0048] By setting the reinforcing groove 19 and the pressing groove 23, and by optimizing the structural shape, the rigidity and deformation resistance of the housing 7 and the filter plate 2 are enhanced respectively, making the housing 7 and the filter plate 2 less prone to damage when subjected to external impact, and extending their service life.

[0049] By connecting ear 1 9, connecting ear 2 10, connecting opening ring 14, fixing rubber sleeve 15 and limiting rubber sleeve 16, the disassembly of housing 7 and housing cover 8 is simple. Just push the connecting opening ring 14 to make the limiting rubber sleeve 16 disengage from the limiting groove 13, and the housing 1 can be opened to clean or replace the filter plate 2 and its interior without complicated tools, which greatly reduces the difficulty and cost of maintenance.
