Description

Technical Field

[0001] This invention relates to the field of tire cleaning technology, and more specifically to an automatic tire cleaning device for ATVs. Background Technology

[0002] ATVs are easy to drive on any terrain due to their uneven tires. They can travel freely on terrains that are difficult for ordinary vehicles to pass through. However, since ATVs are often used in environments with poor road conditions, the tires often get covered in mud and need to be cleaned frequently.

[0003] The Chinese patent authorization announcement number is CN206475866U, entitled "A Beach Vehicle Tire Cleaning Device". It includes a water collection tank, a support is set on one side of the water collection tank, and a water spray pipe is set on the upper end of the support. The water spray pipe is connected to a tap water pipe. A brushing device is also set on one side of the water collection tank. The brushing device includes an active brush and a driven brush. When cleaning the tire, the tire is placed in the water collection tank. Then, the tire rotates, which drives the active brush to rotate, and in turn drives the driven brush to rotate. The two brushes rotate in opposite directions, which facilitates the cleaning of the tire. At the same time, the water spray pipe rinses the tire.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: when cleaning the tires of the beach buggy, the tires need to be in the water collection tank before cleaning can be carried out. That is, the tires need to be removed from the vehicle body, or the beach buggy needs to be stopped so that the tires can be placed in the water collection tank, that is, the tires need to be connected to a separately set cleaning device before cleaning. Such cleaning delays the use of the beach buggy and is not convenient. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic tire cleaning device for beach buggies, so as to solve the technical problem that the existing technology requires the beach buggy to stop and then connect the tire to a separately set cleaning device for cleaning, which is not convenient.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

The booster air box is connected to a support guide rail, the nozzle is connected to one side of the brush body, and the nozzle cooperates with the top of the wheel. An elastic corrugated telescopic tube is connected between the nozzle and the booster air box. A pressure sensing switch is connected to the inner wall of the booster air box. An exhaust control assembly electrically connected to the pressure sensing switch is provided inside the booster air box. The port of the elastic corrugated telescopic tube near the inside of the booster air box cooperates with the exhaust control assembly. An inflation piston cylinder is connected to the support guide rail. An inflation one-way valve assembly is connected between the top side of the inflation piston cylinder and the booster air box, and an intake one-way valve assembly is connected to the other top side of the inflation piston cylinder. A reciprocating piston assembly that cooperates with the second linkage rod is provided inside the inflation piston cylinder.

[0011] As a further embodiment of the present invention: the exhaust control assembly includes a second stepper motor and a closed rotating block. The second stepper motor is connected to the inner wall of the booster air box, and the air pressure sensing switch is electrically connected to the second stepper motor. The closed rotating block is disposed in conjunction with the port of the elastic corrugated telescopic tube near the inside of the booster air box, and the closed rotating block is connected to the second stepper motor.

[0012] As a further aspect of the present invention: the reciprocating piston assembly includes a piston block and a linkage push plate. The piston block is slidably connected inside the inflatable piston cylinder. A second return spring is connected between the piston block and the top of the inflatable piston cylinder. The linkage push plate is connected below the piston block and cooperates with the second linkage rod.

[0013] As a further aspect of the present invention: the position adjustment mechanism includes a first stepper motor, the first stepper motor is connected to the connecting slider, the main shaft end of the first stepper motor is connected to a push arm parallel to the rotating column, the side wall of the rotating column near the push arm is connected to a protruding shank parallel to the push rod, and the inner wall of the slide groove is provided with a one-way switch group that cooperates with the connecting slider, and the one-way switch group is electrically connected to the first stepper motor.

[0014] As a further embodiment of the present invention: the one-way switch group includes a mounting groove and a pressure sensing switch. The mounting groove is formed on the inner wall of the slide groove. A rotating plate is movably connected to the inner wall of the mounting groove via a spring-loaded hinge, and the end of the rotating plate is positioned below the connecting slider. The pressure sensing switch is disposed on the lower end face of the rotating plate and is electrically connected to the first stepper motor.

[0015] As a further aspect of the present invention: the tire detection sensor assembly includes a laser sensor and a controller, the laser sensor is connected to the bottom of the support rail, the controller is connected to the upper side of the support rail, and the controller is electrically connected to the laser sensor.

[0016] As a further aspect of the present invention: the transmission assembly includes a first transmission wheel and a second transmission wheel, the first transmission wheel being coaxially connected to a first anti-slip wheel, the second transmission wheel being coaxially connected to a rotating column, and a transmission belt connecting the first transmission wheel and the second transmission wheel.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention relies on a tire detection sensor assembly to detect dirt on the tire surface during the operation of the ATV. If the tire detection sensor assembly detects excessive dirt or the driver finds that excessive deposits on the tire surface affect its use, the electric telescopic rod is activated to extend. The electric telescopic rod then drives the second anti-slip wheel to descend and align with the first anti-slip wheel coaxially connected to the wheel. In this way, the rotating wheel can drive the first anti-slip wheel to rotate through the second anti-slip wheel. The first anti-slip wheel then drives the rotating column to rotate through the transmission assembly. The rotating column drives the push rod to rotate in a circular motion. The push rod repeatedly pushes the linkage plate. The linkage plate, through the first and second linkage rods, drives the brush body to slide back and forth to clean the surface of the rotating wheel. In this way, the brush body can automatically move and clean by relying on the power of the wheel's rotation, without the need for separate control of the brush body's movement. Moreover, cleaning can be completed during the driving process, making it convenient and effective to use.

[0019] 2. In this invention, during the reciprocating motion of the brush body driven by the linkage plate through the first and second linkage rods, the rotating second linkage rod continuously squeezes the linkage push plate, which in turn drives the piston block to compress the air in the inflation piston cylinder. The inflation piston cylinder inflates the air into the booster air box, causing the air in the booster air box to continuously increase in pressure. When the pressure reaches a set value, the air pressure sensor switch causes the corresponding second stepper motor to drive the closed rotating block to rotate and open the elastic corrugated telescopic tube. In this way, the high-pressure gas in the booster air box is sprayed out through the nozzle to act on the wheel, assisting in cleaning and improving the cleaning effect.

[0020] 3. When the electric telescopic rod of the present invention retracts and resets, the connecting slider rises along the slide groove by relying on the rebound force of the support spring. During this process, the connecting slider acts on the corresponding pressure sensing switch, which causes the first step motor to drive the push arm to rotate one revolution. At this time, if the push rod and the convex handle on the rotating column are in the tilted position on the upper side of the rotating column, the push arm can push against the convex handle, causing the rotating column to rotate, thereby driving the push rod to rotate to the horizontal position, avoiding the push rod from being squeezed onto the linkage plate after resetting and causing the brush body to move onto the wheel.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-6 As shown, an automatic tire cleaning device for beach buggies includes a frame 1, on which wheels 2 are rotatably mounted. The wheels 2 are driven to rotate by the motor transmission assembly of the beach buggy itself, thereby enabling the entire beach buggy to operate.

[0031] A horizontal support rail 23 is installed above the wheel 2. The support rail 23 is fixedly connected to the frame 1. A tire detection sensor assembly is installed at the bottom of the support rail 23. The tire detection sensor assembly includes a laser sensor 24 and a controller 27. The laser sensor 24 is connected to the bottom of the support rail 23 and faces the top of the wheel 2. The controller 27 is connected to the upper side of the support rail 23 and is electrically connected to the laser sensor 24. The laser sensor 24 can be a laser rangefinder sensor to detect the change in distance between its position and the surface of the wheel 2. Since the surface of the ATV tire has deep grooves, the laser sensor 24 can detect the corresponding distance data and feed it back to the controller 27. When the wheel 2 is covered with mud, sand and other dirt, the mud and sand will fill the grooves on the surface of the wheel 2. The change data detected by the laser sensor 24 is fed back to the controller 27, and the controller 27 feeds back control signals based on the deviation change data.

[0032] A brush body 31 is slidably connected to the support rail 23. The brush body 31 is an elastic soft brush. A first return spring 26 is connected between the brush body 31 and the support rail 23. The first return spring 26 is compressible. The brush body 31 is initially positioned close to the frame 1. When it is necessary to clean the wheel 2, it moves laterally along the support rail 23, thus scraping off the mud and sand on the surface of the wheel 2. During this process, the first return spring 26 is compressed to generate a rebound force.

[0033] The top of the brush body 31 is hinged to a first linkage rod 11. The end of the support rail 23 near the frame 1 is hinged to a second linkage rod 12. The ends of the first linkage rod 11 and the second linkage rod 12 are hinged to a linkage plate 10. When the linkage plate 10 is pushed upward, it can squeeze and open the first linkage rod 11 and the second linkage rod 12. The opened first linkage rod 11 and the second linkage rod 12 push the brush body 31 laterally along the support rail 23 to facilitate cleaning the surface of the wheel 2.

[0034] An electric telescopic rod 6, which is electrically connected to the tire detection sensor assembly, is also connected to the side wall of the frame 1 near the wheel 2. The electric telescopic rod 6 is equipped with a manual control switch, which can be manually controlled to extend and retract. The telescopic end of the electric telescopic rod 6 is rotatably connected to the first anti-slip wheel 4. The wheel 2 is coaxially connected to the second anti-slip wheel 3, which is aligned with the first anti-slip wheel 4. When the tire detection sensor assembly detects that there is a lot of mud and sand on the surface of the wheel 2, it sends a feedback signal to cause the electric telescopic rod 6 to extend. The electric telescopic rod 6 then drives the first anti-slip wheel 4 to descend and contact the second anti-slip wheel 3. Thus, during the ride of the ATV, as the wheel 2 rotates, the second anti-slip wheel 3 rotates synchronously, thereby causing the first anti-slip wheel 4 to rotate.

[0035] A groove 13 is provided on the side wall of the frame 1 near the electric telescopic rod 6. A connecting slider 14 is slidably connected in the groove 13. A support spring 18 is connected between the connecting slider 14 and the bottom of the groove 13. The support spring 18 is compressible. A rotating column 20 is rotatably connected to one side of the connecting slider 14. A push rod 8 that cooperates with the linkage plate 10 is vertically connected to the end of the rotating column 20. The linkage plate 10 is on the rotation trajectory of the push rod 8. A transmission assembly is provided between the rotating column 20 and the first anti-slip wheel 4. The transmission assembly includes a first transmission wheel 5 and a second transmission wheel 9. The first transmission wheel 5 is coaxially connected to the first anti-slip wheel 4. The second transmission wheel 9 is coaxially connected to the rotating column 20. A transmission belt 7 is connected between the first transmission wheel 5 and the second transmission wheel 9.

[0036] When the electric telescopic rod 6 drives the first anti-slip wheel 4 to descend and align with the second anti-slip wheel 3, the first transmission wheel 5 pulls the second transmission wheel 9 and the rotating column 20 via the transmission belt 7. The rotating column 20 then slides down the slide groove 13 along the connecting slider 14, compressing the support spring 18. Then, as the wheel 2 drives the second anti-slip wheel 3 to rotate, the first anti-slip wheel 4 rotates accordingly, and the first transmission wheel 5 and the transmission belt 7 drive the second transmission wheel 9 to rotate. The second transmission wheel 9 then drives the rotating column 20 to rotate. As a result, the push rod 8 at the end of the rotating column 20 rotates. Whenever the rotating push rod 8 rotates to the position of the linkage plate 10, its end presses against the linkage plate 10. This causes the linkage plate 10 to rise, and it should be noted that the linkage plate 10 has sufficient width to maintain contact with the end of the push rod 8 when it moves laterally during the lifting process. In this way, the raised linkage plate 10 drives the brush body 31 to move laterally along the support guide rail 23 to clean the surface of the wheel 2. When the push rod 8 rotates and disengages from the linkage plate 10, the brush body 31 slides back to its original position by the rebound force of the first return spring 26, and the linkage plate 10 descends to its original position, waiting for the push rod 8 to push again. In this way, the brush body 31 can reciprocate, which is convenient for continuous cleaning. And because the wheel 2 rotates and moves, it is convenient for the brush body 31 to clean one circle of the wheel 2.

[0037] The connecting slider 14 is provided with a position adjustment mechanism that cooperates with the rotating column 20. The position adjustment mechanism includes a first stepper motor 22, which is connected to the connecting slider 14. The main shaft end of the first stepper motor 22 is connected to a push arm 21 parallel to the rotating column 20. A protruding shank 19 that is parallel and aligned with the push rod 8 is vertically connected to the side wall of the rotating column 20 near the push arm 21. A one-way switch group that cooperates with the connecting slider 14 is provided on the inner wall of the slide groove 13, and the one-way switch group is electrically connected to the first stepper motor 22. The one-way switch group includes a mounting groove 15 and a pressure sensing switch 17. The mounting groove 15 is opened on the inner wall of the slide groove 13. A rotating plate 16 is movably connected to the inner wall of the mounting groove 15 through a spring hinge, and the end of the rotating plate 16 is fitted below the connecting slider 14. The pressure sensing switch 17 is installed on the lower end face of the rotating plate 16 and is electrically connected to the first stepper motor 22.

[0038] When the electric telescopic rod 6 lowers the first anti-slip wheel 4, causing the connecting slider 14 to descend synchronously, the connecting slider 14 slides down along the slide groove 13, pressing down on the end of the rotating plate 16 from top to bottom. The rotating plate 16 first rotates and retracts into the mounting groove 15 due to the pressure. Then, when the connecting slider 14 has completely passed through, the rotating plate 16 rotates back to its original position, and the pressure sensor switch 17 is not subjected to pressure. When the electric telescopic rod 6 retracts and resets, the connecting slider 14 rises under the rebound force of the support spring 18 and passes from bottom to top through the position of the rotating plate 16. At this time, the pressure sensor switch 17 at the bottom of the rotating plate 16 is pressed down. The sensor generates a trigger to activate the first step motor 22, which in turn drives the push arm 21 to rotate one revolution. If the push rod 8 and the parallel aligned protrusion 19 are in the space above the rotating column 20, i.e. in the tilted position, the push arm 21 can push against the protrusion 19 during the rotation, causing the tilted protrusion 19 to rotate to the horizontal position by the rotating column 20. The push rod 8 will then rotate to the horizontal position simultaneously, thus preventing the tilted push rod 8 from contacting the upper linkage plate 10 when the rotating column 20 and the connecting slider 14 are raised, which would cause the brush body 31 to slide onto the wheel 2 and contact it without cleaning the wheel 2.

[0039] A high-pressure air blowing assembly that cooperates with the brush body 31 is also provided on the support guide rail 23. The air blowing assembly includes a booster air box 30 and a nozzle 28. The booster air box 30 is connected to the support guide rail 23, and the nozzle 28 is connected to one side of the brush body 31 and cooperates with the top of the wheel 2. An elastic corrugated telescopic tube 29 connects the nozzle 28 and the booster air box 30. An air pressure sensor switch 36 is connected to the inner wall of the booster air box 30. An exhaust control assembly electrically connected to the air pressure sensor switch 36 is provided inside the booster air box 30. The port of the elastic corrugated telescopic tube 29 near the inside of the booster air box 30 cooperates with the exhaust control assembly. The exhaust control assembly includes a second stepper motor 39 and a closed rotating block 38. The second stepper motor 39 is connected to the inner wall of the booster air box 30, and the air pressure sensor switch 36 is connected to the air pressure sensor switch 38. 36 is electrically connected to the second stepper motor 39. The closed rotating block 38 is fitted at the port of the elastic corrugated telescopic tube 29 near the inside of the booster air box 30. The closed rotating block 38 is connected to the second stepper motor 39 through the bracket. When the air pressure inside the booster air box 30 rises to a certain value, the air pressure sensing switch 36 feeds back a signal to start the second stepper motor 39. The second stepper motor 39 then drives the closed rotating block 38, which was originally sealing the port of the elastic corrugated telescopic tube 29, to rotate around the main shaft end once. In this way, the closed rotating block 38 first deflects away from the port of the elastic corrugated telescopic tube 29, and then resets to seal it. During the deflection process, the high-pressure gas inside the booster air box 30 is discharged and sprayed out from the nozzle 28 through the elastic corrugated telescopic tube 29 to blow the adhering material on the surface of the wheel 2. The high air pressure impacts the adhering material to improve the cleaning effect.

[0040] An inflation piston cylinder 25 is connected to the support guide rail 23. An inflation one-way valve assembly 33 is connected between the top side of the inflation piston cylinder 25 and the booster air box 30. The inflation one-way valve assembly 33 can only allow air in the inflation piston cylinder 25 to enter the booster air box 30 and cannot flow back from the inflation piston cylinder 25 to the inflation piston cylinder 25. An intake one-way valve assembly 34 is connected to the other side of the top of the inflation piston cylinder 25. The intake one-way valve assembly 34 can only allow external air to be drawn into the inflation piston cylinder 25 and cannot allow air to be discharged through the intake one-way valve assembly 34.

[0041] The inflatable piston cylinder 25 is equipped with a reciprocating piston assembly that cooperates with the second linkage rod 12. The reciprocating piston assembly includes a piston block 37 and a linkage push plate 32. The piston block 37 is slidably connected inside the inflatable piston cylinder 25. A second return spring 35 is connected between the piston block 37 and the top of the inflatable piston cylinder 25. The second return spring 35 is compressible. The linkage push plate 32 is connected to the lower part of the piston block 37 via a rod and cooperates with the second linkage rod 12. Whenever the push rod 8 pushes the linkage plate 10 upward, the linkage plate 10 squeezes and opens the first linkage rod 11 and the second linkage rod 12. During this process, the second linkage rod 12 rotates and squeezes against the linkage push plate 32, causing the linkage push plate 32 to push upward. The linkage push plate 32 pushes the piston block 37 to slide into the inflation piston cylinder 25. In this way, the air in the inflation piston cylinder 25 is inflated into the booster air box 30 through the inflation one-way valve assembly 33. During this process, the second return spring 35 is compressed and generates a rebound force. When the push rod 8 disengages from the linkage plate 10, the linkage plate 10 descends and resets. At this time, the first linkage rod 11 and the second linkage rod 12 retract. In this way, the piston block 37 connected to the linkage push plate 32 is reset by the rebound force of the second return spring 35, so that the inflation piston cylinder 25 can draw in air from the outside through the suction one-way valve assembly 34, and then inflate the booster air box 30 again. In this way, the booster air box 30 can be continuously inflated.

[0042] The working principle of this invention: The ATV moves by rotating wheels 2. The tire detection sensor assembly detects the deposits on the wheels 2. The tire detection sensor assembly uses a laser sensor 24 to detect changes in the distance between the deposited material and the surface of the wheels 2. Since the surface of the ATV tires has deep grooves, the laser sensor 24 can detect the corresponding distance data and feed it back to the controller 27. When the wheels 2 are covered with mud, sand, or other dirt, the mud and sand will fill the grooves on the surface of the wheels 2. The change data detected by the laser sensor 24 is fed back to the controller 27, and the controller 27 then provides control signal feedback based on the deviation change data. This causes the electric telescopic rod 6 to extend, which in turn causes the first anti-slip wheel 4 to descend and come into contact with the second anti-slip wheel 3. Thus, during the movement of the beach buggy, as the wheel 2 rotates, the second anti-slip wheel 3 rotates synchronously, thereby causing the first anti-slip wheel 4 to rotate. When the first anti-slip wheel 4 descends and causes the connecting slider 14 to descend synchronously, the connecting slider 14 slides down along the slide groove 13 and presses the end of the rotating piece 16 from top to bottom. The rotating piece 16 first rotates and retracts into the mounting groove 15 due to the pressure. Then, when the connecting slider 14 has completely passed through, the rotating piece 16 rotates back to its original position, and the pressure sensing switch 17 is not subjected to the pressure action.

[0043] When wheel 2 drives the second anti-slip wheel 3 to rotate, the first anti-slip wheel 4, which is in contact with the second anti-slip wheel 3, also rotates. It then drives the second transmission wheel 9 to rotate via the first transmission wheel 5 and the transmission belt 7. The second transmission wheel 9, in turn, drives the rotating column 20 to rotate. This causes the push rod 8 at the end of the rotating column 20 to rotate. Whenever the rotating push rod 8 reaches the position of the linkage plate 10, its end presses against the linkage plate 10, causing the linkage plate 10 to rise. The rising linkage plate 10 then presses and expands the first linkage rod 11 and the second linkage rod. The first and second linkage rods 11 and 12, which are thus spread apart, push the brush body 31 laterally along the support guide rail 23 to clean the surface of the wheel 2. When the push rod 8 rotates and disengages from the linkage plate 10, the brush body 31 slides back to its original position by the rebound force of the first return spring 26, and the linkage plate 10 descends to its original position, waiting for the push rod 8 to push again. This allows the brush body 31 to reciprocate, which is convenient for continuous cleaning. Furthermore, since the wheel 2 rotates and moves, it is convenient for the brush body 31 to clean the wheel 2 around its circumference.

[0044] Furthermore, during the reciprocating lifting and lowering process of the linkage plate 10, whenever the linkage plate 10 squeezes and opens the first linkage rod 11 and the second linkage rod 12, the second linkage rod 12 rotates and squeezes against the linkage push plate 32, causing the linkage push plate 32 to push upward. The linkage push plate 32 then pushes the piston block 37 to slide into the inflation piston cylinder 25. In this way, the air in the inflation piston cylinder 25 is inflated into the booster air box 30 through the inflation one-way valve assembly 33. During this process, the second return spring 35 is compressed and generates a rebound force. When the push rod 8 disengages from the linkage plate 10, the linkage plate 10 descends and resets. At this time, the first linkage rod 11 and the second linkage rod 12 retract. In this way, the piston block 37 connected to the linkage push plate 32 is reset by the rebound force of the second return spring 35, so that the inflation piston cylinder 25 can draw in air from the outside through the suction one-way valve assembly 34, and then inflate the booster air box 30 again. In this way, the booster air box 30 can be continuously inflated.

[0045] When the internal air pressure of the booster air box 30 rises to a certain value, the air pressure sensor switch 36 sends a signal to start the second stepper motor 39. The second stepper motor 39 then drives the sealing rotating block 38, which originally closed the port of the elastic corrugated telescopic tube 29, to rotate around the main shaft end once. In this way, the sealing rotating block 38 first deflects away from the port of the elastic corrugated telescopic tube 29, and then resets to close it. During the deflection process, the high-pressure gas inside the booster air box 30 is discharged and sprayed out from the nozzle 28 through the elastic corrugated telescopic tube 29 to blow the adhering material on the surface of the wheel 2. The high air pressure impacts the adhering material, improving the cleaning effect.

[0046] After a certain period of cleaning, if the tire detection sensor assembly does not detect a significant amount of residue on the surface of wheel 2, the controller 27 will control the electric telescopic rod 6 to retract and reset. This separates the second anti-slip wheel 4 from the first anti-slip wheel 3, preventing further rotation of wheel 2. Simultaneously, the connecting slider 14 rises under the restoring force of the support spring 18, passing from bottom to top where the rotating plate 16 is located. At this time, the pressure sensor switch 17 at the bottom of the rotating plate 16 is pressed and triggered, activating the first stepper motor 22. 22 then drives the push-top rotating arm 21 to rotate one revolution. At this time, if the push-top rod 8 and the parallel aligned protruding shank 19 are in the space above the rotating column 20, that is, in the tilted position, the push-top rotating arm 21 can push against the protruding shank 19 during the rotation, causing the tilted protruding shank 19 to rotate to the horizontal position by relying on the rotating column 20. The push-top rod 8 will then rotate to the horizontal position simultaneously, thereby preventing the tilted push-top rod 8 from contacting the upper linkage plate 10 when the rotating column 20 and the connecting slider 14 are raised, causing the brush body 31 to slide onto the wheel 2 and contact it without cleaning the wheel 2.

[0047] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
