Abstract

This invention discloses an assembled air filter for electric motorcycles, relating to the field of air filtration technology. The assembled air filter for electric motorcycles includes a housing, a filter cartridge, a dust collection box, a cleaning mechanism, a swing mechanism, a drive mechanism, and a transmission mechanism. The filter cartridge is installed inside the housing and connected to a vent pipe. The cleaning mechanism's cleaning cylinder is sleeved on the outside of the filter cartridge, and a cleaning brush is provided on the inner wall of the cleaning cylinder. The swing mechanism uses vehicle vibration to drive the cleaning cylinder to move axially along the filter cartridge.

The cleaning brush, under the combined action of axial movement and circumferential rotation, brushes the outer surface of the filter cartridge, removing dust which enters the dust collection box and can be discharged through a discharge chute. This air filter can reduce dust accumulation on the filter cartridge surface, improving cleaning uniformity and filtration stability.

Description

Technical Field

[0001] This invention relates to the field of air filtration device technology, and more specifically to an assembled air filter for electric motorcycles. Background Technology

[0002] With the increasing electrification of electric motorcycle power systems and overall vehicles, the requirements for air filtration, heat dissipation, and dust protection of components inside the vehicles are gradually increasing. Existing electric motorcycles typically have air filters installed in the air intake channel, heat dissipation channel, or at the front end of the exhaust device. These filters consist of a housing, filter element, air intake port, air outlet pipe, and connecting joints, forming a filtration structure that intercepts dust, sand, and other impurities from the outside air before it enters the exhaust device or the cavity to be protected.

[0003] During long-term use, dust easily accumulates on the outer surface of existing electric motorcycle air filters, especially on dusty roads, in humid environments, or under conditions of frequent vehicle start-stop operation. This dust buildup can lead to increased intake resistance, reduced airflow, and fluctuations in filtration efficiency. To reduce filter clogging, some air filters incorporate scrapers, vibrators, or other cleaning mechanisms to clean the filter surface. However, these cleaning mechanisms typically only act in a single direction, resulting in limited cleaning coverage and potential for inadequate cleaning in certain areas. Summary of the Invention

[0004] An assembled air filter for electric motorcycles is provided to improve the technical problems of dust accumulation on the filter element surface and the limited cleaning direction during the use of existing air filters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An assembled air filter for electric motorcycles includes a housing and a filter cartridge. The housing has several through holes, and a vent pipe is installed on one side of the housing. The filter cartridge further includes: a cleaning mechanism comprising a cleaning cylinder sleeved on the outside of the filter cartridge and a cleaning brush disposed on the inner wall of the cleaning cylinder; a swing mechanism, driven by the cleaning mechanism, for driving the cleaning cylinder to move axially along the filter cartridge under the vibration of the electric motorcycle; a transmission mechanism connected to the cleaning cylinder; and a drive mechanism, driven by the transmission mechanism, for driving the transmission mechanism to rotate under the action of airflow in the vent pipe, thereby causing the cleaning cylinder to rotate circumferentially around the filter cartridge via the transmission mechanism.

[0006] Preferably, it further includes: a positioning ring, installed on the inner wall of the housing, with one end of the filter cartridge inserted into the positioning ring to radially position the filter cartridge; and a mounting hole, formed on the side of the housing away from the vent pipe, with a sealing seat threadedly connected to the mounting hole, the sealing seat being used to seal and limit the mounting end of the filter cartridge.

[0007] Preferably, it further includes: a dust collection box, installed at the bottom of the housing and communicating with the interior of the housing, wherein a discharge groove is provided through the bottom of the dust collection box; and a sealing plug, inserted into the discharge groove, for sealing the discharge groove when not discharging.

[0008] Preferably, the cleaning mechanism further includes: a fixing plate, fixedly installed inside the housing, with a through groove therethrough; two sliding cylinders, both slidably connected to the fixing plate and capable of sliding along the length of the fixing plate; a horizontal plate connected between the two sliding cylinders; a toothed plate installed on the top surface of the horizontal plate; two connecting seats, respectively installed on the bottom surfaces of the two sliding cylinders; and a cleaning cylinder rotatably connected between the two connecting seats and sleeved on the outside of the filter cylinder.

[0009] Preferably, the cleaning mechanism further includes: multiple ventilation slots, all extending through the cleaning cylinder; and multiple guide holes, all located on the side of the cleaning cylinder near the ventilation pipe.

[0010] Preferably, the swing mechanism includes: a horizontal shaft passing through the housing and rotatably connected to the housing; a gear installed on the portion of the horizontal shaft located inside the housing and meshing with the gear plate; and two inertial swing blocks, respectively installed on the two ends of the horizontal shaft located outside the housing.

[0011] Preferably, the transmission mechanism includes: a fixed ring, which is fixedly connected to the inner wall of the housing; a rotating ring, which is rotatably connected to the fixed ring through a mounting groove; a bevel gear ring, which is fixedly connected to the rotating ring; and a plurality of insert rods, which are installed on the side of the rotating ring away from the fixed ring and are respectively inserted into a plurality of guide holes.

[0012] Preferably, the driving mechanism includes: a disc installed inside the vent pipe, the disc having multiple vent holes extending through it; a rotating rod rotatably installed at the center of the disc; a fan blade installed at one end of the rotating rod and located inside the vent pipe; and a first bevel gear installed at the other end of the rotating rod.

[0013] Preferably, the drive mechanism further includes: a vertical rod that passes through the top surface of the housing and is rotatably connected to the housing; a second bevel gear that is mounted on the upper end of the vertical rod and meshes with the first bevel gear; and a third bevel gear that is mounted on the lower end of the vertical rod and meshes with the bevel gear ring.

[0014] Preferably, the diameter of the vent hole on the side closer to the housing is larger than the diameter on the side farther from the housing, the fan blade is located on the side of the disc farther from the housing, and all the vent holes are oriented towards the fan blade; the end of the vent pipe away from the housing is connected to a connector, which is used to connect to the air extraction device or heat dissipation air intake pipe of the electric motorcycle.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Through the cooperation of the cleaning mechanism, the swing mechanism, the drive mechanism and the transmission mechanism, the cleaning cylinder can move axially and rotate circumferentially relative to the filter cylinder under the action of vehicle vibration and airflow, so that the cleaning brush forms a composite brushing path along the outer surface of the filter cylinder, thereby helping to reduce the local accumulation of dust on the outer surface of the filter cylinder and reduce the risk of filter cylinder blockage.

[0016] 2. By using a plug rod to engage with a guide hole extending axially, the cleaning cylinder can still receive the circumferential power transmitted by the rotating ring when moving axially. This helps to maintain the transmission coordination between axial movement and circumferential rotation, and reduces the possibility of separation or deviation during the movement of the cleaning cylinder.

Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] An assembled air filter for electric motorcycles, which can be installed in the battery compartment cooling intake channel, motor cooling channel, controller cooling channel, or front end of the vehicle body exhaust device of the electric motorcycle.

[0023] Example: Figures 1 to 7As shown, an assembled air filter for electric motorcycles, used to intercept dust and sand particles before cooling air enters the protected component, includes a housing 101 for accommodating a filter cartridge 110 and a cleaning mechanism 120. The housing 101 has several through holes 102 for allowing outside air to enter. A vent pipe 104 is installed on one side of the housing 101, and a connector 105 is connected to the other end of the vent pipe 104. The connector 105 is used to connect to the suction pipe of an air extraction device, allowing air filtered by the filter cartridge 110 inside the housing 101 to enter the air extraction device through the vent pipe 104 and the connector 105. A mounting hole is provided on the side of the housing 101 away from the vent pipe 104, and a sealing seat 103 is threaded onto the mounting hole. The sealing seat 103 is used to seal and limit the mounting end of the filter cartridge 110. The filter cartridge 110 is a hollow cylindrical filter element. Outside air enters the interior of the housing 101 through the through hole 102 on the housing 101, passes through the filter material on the outer periphery of the filter cartridge 110 and enters the inner cavity of the filter cartridge 110, and is then discharged through the vent pipe 104.

[0024] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a positioning ring 1011 is installed on the inner wall of the housing 101. The positioning ring 1011 cooperates with the end of the filter cartridge 110 and is used to position the filter cartridge 110. After the sealing seat 103 is connected to the housing 101, the sealing seat 103 fixes the filter cartridge 110 inside the housing 101, so that the filter cartridge 110 is kept in a predetermined installation position inside the housing 101. When the filter cartridge 110 is fixed inside the housing 101, the filter cartridge 110 communicates with the interior of the vent pipe 104. An mounting plate 109 is installed on the side of the housing 101. The mounting plate 109 is used to install the housing 101 in the corresponding installation position on the electric motorcycle. A sealing ring is provided on the positioning ring 1011. The sealing ring abuts against the end of the filter cartridge 110 to prevent unfiltered air from entering the vent pipe 104 around the filter cartridge 110.

[0025] A dust collection box 106 is installed at the bottom of the housing 101, and the dust collection box 106 is connected to the interior of the housing 101. A discharge trough 107 is provided through the bottom of the dust collection box 106, and a sealing plug 108 is inserted into the discharge trough 107. A dust discharge port is provided between the bottom of the housing 101 and the dust collection box 106, and a dust guide plate inclined towards the dust collection box 106 is provided at the dust discharge port. The dust guide plate is not shown in the figure.

[0026] Specifically, during installation, the filter cartridge 110 enters the housing 101 from the side away from the vent pipe 104, and is positioned at the end by the positioning ring 1011. Then, the sealing seat 103 is threaded into the mounting hole on the housing 101, thus limiting the movement of the filter cartridge 110 while maintaining communication between the outlet side of the filter cartridge 110 and the vent pipe 104. When cleaning or replacing the filter cartridge 110, the connection between the sealing seat 103 and the housing 101 is released, allowing the filter cartridge 110 to be removed from the housing 101.

[0027] like Figures 3 to 5 As shown, the assembled air filter for electric motorcycles also includes a cleaning mechanism 120. The cleaning mechanism 120 includes a fixing plate 121, which is fixedly installed inside the housing 101. A strip groove 1211 is formed through the fixing plate 121. Two sliding cylinders 123 are slidably connected to the fixing plate 121. The two sliding cylinders 123 can slide along the length of the strip groove 1211. The two sliding cylinders 123 are connected by a horizontal plate 122, so that the two sliding cylinders 123 keep moving synchronously. A toothed plate 124 is installed on the top surface of the horizontal plate 122, and a connecting seat 125 is installed on the bottom surface of each of the two sliding cylinders 123. A cleaning cylinder 126 is rotatably connected between the two connecting seats 125. The cleaning cylinder 126 is sleeved on the outside of the filter cylinder 110. Multiple cleaning brushes 127 are installed on the inner wall of the cleaning cylinder 126, which are positioned facing the outer surface of the filter cylinder 110 and are used to clean the filter cylinder 110 when the cleaning cylinder 126 moves. A ventilation groove 128 is provided through the cleaning cylinder 126 to reduce the obstruction of airflow by the cleaning cylinder 126; a plurality of guide holes 129 are provided on the side of the cleaning cylinder 126 near the ventilation pipe 104.

[0028] Specifically, the fixed plate 121 provides a supporting foundation for the cleaning mechanism 120, the strip groove 1211 constrains the movement direction of the slide cylinder 123, the horizontal plate 122 connects the two slide cylinders 123 into a synchronous movement structure, and the toothed plate 124 is used to receive the linear motion driving force transmitted by the swing mechanism 130. The connecting seat 125 is located below the slide cylinder 123 and rotatably supports the cleaning cylinder 126 between the two connecting seats 125, so that the cleaning cylinder 126 can move axially along the filter cylinder 110 with the slide cylinder 123 and can also rotate circumferentially around the filter cylinder 110 relative to the connecting seat 125.

[0029] like Figures 3 to 5As shown, the assembled air filter for electric motorcycles also includes a swing mechanism 130. The swing mechanism 130 includes a horizontal shaft 131, which passes through the housing 101 and is rotatably connected to the housing 101. A gear 132 is mounted on the portion of the horizontal shaft 131 located inside the housing 101, and the gear 132 meshes with a gear plate 124. Inertial swing blocks 133 are mounted on both ends of the horizontal shaft 131 located outside the housing 101. The inertial swing blocks 133 are located outside the housing 101 and swing or displace when affected by vehicle vibration during the operation of the electric motorcycle, transmitting the swing or displacement to the horizontal shaft 131, causing the horizontal shaft 131 to drive the gear 132 to rotate.

[0030] Furthermore, a reset elastic element is provided between the horizontal shaft 131 and the housing 101. The reset elastic element is not shown in the figure. One end of the reset elastic element is connected to the housing 101, and the other end is connected to the horizontal shaft 131 or the inertial swing block 133. The inertial swing block 133 is eccentrically arranged relative to the horizontal shaft 131. When the electric motorcycle generates alternating vibrations, the inertial swing block 133 drives the horizontal shaft 131 to swing within a preset angle range. The reset elastic element is used to drive the horizontal shaft 131 to reverse and reset after the vibration weakens or the swing reaches the limit position.

[0031] Specifically, when the electric motorcycle vibrates, the inertial pendulum 133 moves relative to the housing 101 under the action of inertia, the horizontal shaft 131 rotates with the inertial pendulum 133, and the gear 132 rotates with the horizontal shaft 131. Since the gear 132 meshes with the toothed plate 124, the rotation of the gear 132 is converted into the linear motion of the toothed plate 124. The toothed plate 124 drives the two sliding cylinders 123 to move along the strip groove 1211 through the horizontal plate 122. The sliding cylinders 123 then drive the cleaning cylinder 126 to move axially along the filter cylinder 110 through the connecting seat 125, so that the cleaning brush 127 axially brushes the outer surface of the filter cylinder 110.

[0032] like Figures 3 to 5 As shown, the assembled air filter for electric motorcycles also includes a transmission mechanism 150. The transmission mechanism 150 includes a fixed ring 151, which is fixedly connected to the inner wall of the housing 101. A rotating ring 152 is rotatably connected to the fixed ring 151. The rotating ring 152 is mounted on the fixed ring 151 through a mounting groove 154, allowing the rotating ring 152 to rotate relative to the fixed ring 151. A bevel gear ring 153 is fixedly connected to the rotating ring 152. Multiple insert rods 155 are mounted on the side of the rotating ring 152 away from the fixed ring 151, and the multiple insert rods 155 are respectively inserted into multiple guide holes 129 on the cleaning cylinder 126.

[0033] Furthermore, the guide hole 129 extends axially along the filter cartridge 110, and the insertion rod 155 is inserted into the guide hole 129 in a direction parallel to the axial direction of the filter cartridge 110. The effective axial length of the guide hole 129 is greater than the maximum axial travel of the cleaning cartridge 126, and the circumferential width of the guide hole 129 forms a clearance fit with the insertion rod 155, allowing the cleaning cartridge 126 to slide axially relative to the insertion rod 155, while also being able to withstand the circumferential driving force transmitted by the rotating ring 152 through the insertion rod 155. Multiple insertion rods 155 are spaced apart circumferentially along the rotating ring 152 to improve torque transmission stability and reduce the force on a single insertion rod 155.

[0034] Specifically, the fixed ring 151 is used to support and position the rotating ring 152, the mounting groove 154 is used to form a rotational fit between the rotating ring 152 and the fixed ring 151, and the bevel gear ring 153 is used to receive the rotational power transmitted by the drive mechanism 140. After the insertion rod 155 is inserted into the guide hole 129, the rotational motion of the rotating ring 152 can be transmitted to the cleaning cylinder 126 through the insertion rod 155, so that the cleaning cylinder 126 rotates synchronously with the rotating ring 152.

[0035] like Figures 3 to 6 As shown, the assembled air filter for electric motorcycles also includes a drive mechanism 140, which comprises a disc 141 and a vertical rod 146. The disc 141 is installed inside a vent pipe 104, and multiple vent holes 142 are formed through the disc 141. The vent holes 142 are frustoconical, with a larger diameter on the side closer to the housing 101 and a smaller diameter on the side farther from the housing 101. A rotating rod 143 is rotatably mounted at the center of the disc 141. One end of the rotating rod 143 is located inside the vent pipe 104 and has a fan blade 144 mounted thereon. The fan blade 144 is located on the side of the disc 141 away from the housing 101, and all the vent holes 142 on the disc 141 face the fan blade 144. The other end of the rotating rod 143 extends outside the vent pipe 104 and has a first bevel gear 145 mounted thereon.

[0036] A vertical rod 146 passes through the top surface of the housing 101 and is rotatably connected to the housing 101. A second bevel gear 147 is mounted on the upper end of the vertical rod 146, and the second bevel gear 147 meshes with the first bevel gear 145. The lower end of the vertical rod 146 is located inside the housing 101, and a third bevel gear 148 is mounted on the lower end of the vertical rod 146, and the third bevel gear 148 meshes with the bevel gear ring 153. Thus, the rotation of the fan blade 144 can be transmitted sequentially through the rotating rod 143, the first bevel gear 145, the second bevel gear 147, the vertical rod 146, the third bevel gear 148, and the bevel gear ring 153 to the rotating ring 152. The drive mechanism 140 also includes a protective box 149, which is mounted on the top of the housing 101. The first bevel gear 145 132 and the second bevel gear 147 132 are located inside the protective box 149.

[0037] Furthermore, the vents 142 on the disc 141 are guide holes that gradually narrow from the side near the housing 101 to the side away from the housing 101, and the air outlet direction of each vent 142 is towards the air-receiving surface of the fan blade 144. The total flow area of ​​the multiple vents 142 is set to a preset ratio not less than the effective flow area of ​​the vent pipe 104, so as to reduce the obstruction of the disc 141 to the airflow in the vent pipe 104. Sealed bearings are provided between the rotating rod 143 and the disc 141, and between the vertical rod 146 and the housing 101, to reduce rotational resistance and reduce leakage of unfiltered air or dust from the rotating support.

[0038] Specifically, when the air extraction device is running, outside air enters the housing 101 through the through hole 102, is filtered by the filter cartridge 110, and then flows to the vent pipe 104. When the air passes through the vent pipe 104, it first passes through the vent hole 142 on the disc 141. Since the vent hole 142 is arranged facing the fan blade 144, the airflow acts on the fan blade 144 and drives the fan blade 144 to rotate. The fan blade 144 drives the rotating rod 143 and the first bevel gear 145 to rotate. The first bevel gear 145 drives the vertical rod 146 to rotate through the second bevel gear 147. The vertical rod 146 then drives the bevel gear ring 153 and the rotating ring 152 to rotate through the third bevel gear 148. The rotating ring 152 drives the cleaning cylinder 126 and the cleaning brush 127 to rotate around the filter cartridge 110 through the insert rod 155, thereby forming a circumferential brushing action.

[0039] During the operation of the above structure, the swing mechanism 130 uses vehicle vibration to drive the cleaning cylinder 126 to move axially along the filter cylinder 110, and the drive mechanism 140 uses the airflow in the vent pipe 104 to drive the cleaning cylinder 126 to rotate circumferentially. When the axial movement and circumferential rotation act simultaneously on the cleaning cylinder 126, the cleaning brush 127 forms a composite brushing path on the outer surface of the filter cylinder 110, so that the outer surface of the filter cylinder 110 can be brushed in both the axial and circumferential directions. The dust brushed off by the cleaning brush 127 falls into the dust collection box 106 at the bottom of the housing 101 under the action of gravity. The discharge trough 107 is used to discharge the dust in the dust collection box 106, and the sealing plug 108 is used to close the discharge trough 107 when not discharging, reducing the escape of dust.

[0040] Working principle: In actual use, first install the housing 101 on the corresponding position of the electric motorcycle using the mounting plate 109, and connect the connector 105 to the suction pipe of the suction device. Insert the filter cartridge 110 into the housing 101, so that the end of the filter cartridge 110 is positioned by the positioning ring 1011, and fix the filter cartridge 110 by the sealing seat 103, so that the filter cartridge 110 is connected to the inside of the air pipe 104.

[0041] After the air extraction device is started, outside air enters the housing 101 through the through hole 102 and is filtered through the filter cartridge 110. The filtered air enters the air extraction device through the vent pipe 104 and the connector 105. When the air passes through the vent pipe 104, it drives the fan blade 144 to rotate. The fan blade 144 drives the cleaning cartridge 126 to rotate through the rotating rod 143, the first bevel gear 145, the second bevel gear 147, the vertical rod 146, the third bevel gear 148, the bevel gear ring 153, the rotating ring 152, the insertion rod 155 and the guide hole 129 in sequence, so that the cleaning brush 127 brushes around the filter cartridge 110.

[0042] When the vehicle vibrates during operation, the inertial pendulum 133 drives the horizontal shaft 131 to rotate. The horizontal shaft 131 drives the gear 132 to rotate. The gear 132 meshes with the toothed plate 124 and drives the toothed plate 124 to move linearly. The toothed plate 124 drives the cleaning cylinder 126 to move axially along the filter cylinder 110 through the horizontal plate 122, the slide cylinder 123, and the connecting seat 125. The circumferential rotation and axial movement of the cleaning cylinder 126 combine to cause the cleaning brush 127 to continuously brush the outer surface of the filter cylinder 110. The dust brushed off enters the dust collection box 106. When it is necessary to discharge the dust, the sealing plug 108 is removed from the discharge chute 107, and the dust in the dust collection box 106 can be discharged through the discharge chute 107. After the discharge is completed, the sealing plug 108 is reinserted.
