Description

Technical Field

[0001] This invention relates to the field of vehicle cleaning technology, specifically to a reciprocating vehicle wiping device. Background Technology

[0002] With economic development, vehicles have become an integral part of everyday life for ordinary people. During use and parking, vehicles inevitably accumulate dust, dirt, or stains on their surfaces. This accumulated dust and stains detract from the vehicle's appearance, so vehicles typically need to be washed periodically. Since washing with a car wash gun or high-pressure washer leaves numerous watermarks on the vehicle's exterior, a car wiping device is necessary to remove these watermarks.

[0003] Chinese patent document CN116533939A discloses a tunnel-type automatic car wash machine, including a base frame and a truss mounted above the base frame. The base frame has symmetrically arranged vehicle delivery lines and a shape detection frame at one end for detecting the vehicle's dimensions. Several cleaning racks are located in the middle of the base frame, with several spray nozzles on their inner sides. A cleaning assembly for drying the sides of the vehicle is located below the truss, away from the shape detection frame. A top plate is slidably mounted on the top of the truss. Below the top plate are symmetrically arranged lifting legs, with a top cleaning roller brush for washing the vehicle's top between two lifting legs. Side cleaning roller brushes for washing the sides of the vehicle are also symmetrically arranged below the top plate. When a vehicle passes through, it comes into contact with the cleaning rollers through friction, thus drying the sides of the vehicle.

[0004] The shortcomings of the above-disclosed solution are: during the wiping process of the vehicle exterior, the cleaning roller cannot get close to the vehicle, so it cannot increase the degree of contact between the cleaning roller and the vehicle, thus failing to generate a large wiping force on the vehicle, resulting in poor wiping effect. Summary of the Invention

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 11 As shown, a reciprocating car wiping device of the present invention includes a first fixed seat 1 and a second fixed seat 14 installed at intervals. A connecting frame 2 is installed on the top of both the first fixed seat 1 and the second fixed seat 14. The connecting frame 2 is C-shaped. The connecting frame 2 includes a base, a vertical plate is fixedly installed on the top of the base, and a horizontal plate is fixedly installed on the top of the vertical plate.

[0033] The connecting frame 2 on the first fixed base 1 is the left connecting frame, and the connecting frame 2 on the second fixed base 14 is the right connecting frame. The bottom wall of the horizontal plate of the left connecting frame is slidably fitted with the bottom wall of the horizontal plate of the right connecting frame. The first fixed base 1 is fixedly fitted with the base of the left connecting frame, and the second fixed base 14 is slidably fitted with the base of the right connecting frame. A hydraulic rod 13 is fixedly installed between the vertical plate of the right connecting frame and the second fixed base 14. The hydraulic rod 13 is horizontally arranged, and the telescopic end of the hydraulic rod 13 is fixedly fitted with the vertical plate of the right connecting frame.

[0034] A second slider 10 is slidably mounted on the upper surface of the base. A rotating roller 28 is mounted on the top of the second slider 10. The rotating roller 28 is vertically arranged, and a clean cylinder 29 is fixedly sleeved on the rotating roller 28. The clean cylinder 29 includes a cylinder body, which is fixedly sleeved on the outer surface of the rotating roller 28. A car cleaning towel is wrapped around the outer surface of the cylinder body. The car cleaning towel is made of cotton, fiber, or other materials and has good water absorption.

[0035] A reciprocating mechanism that drives the second slider 10 to move back and forth is installed on the base. The reciprocating mechanism includes a first connecting seat 7, which is slidably installed on the top of the base and is arranged along the length of the base. A first groove is formed on the top of the first connecting seat 7 along its length, and a reciprocating screw 8 is rotatably installed in the first groove. A first motor 15 is fixedly installed on one side of the first connecting seat 7, and the output end of the first motor 15 passes through the first connecting seat 7 and is fixedly engaged with the reciprocating screw 8. The second slider 10 is threadedly connected to the outer surface of the reciprocating screw 8, and the second slider 10 is slidably engaged with the first groove.

[0036] A connector is slidably mounted on the top of the base, with one end passing through and slidably connected to a vertical plate. The bottom of the connector is connected to a reciprocating mechanism, and a limit plate 17 is fixedly mounted on the top of the connector. The connector includes a first connecting rod 4, which is slidably mounted on the top of the base. One end of the first connecting rod 4 passes through and slidably engages with the vertical plate, while the other end is fixedly engaged with a first connecting seat 7. A connecting plate 6 is fixedly mounted at the middle position of the first connecting rod 4, and the connecting plate 6 is vertically arranged and perpendicular to the first connecting rod 4.

[0037] A second connecting rod 18 is fixedly installed on the top of the connecting plate 6. The second connecting rod 18 is horizontally arranged and perpendicular to the connecting plate 6. One end of the second connecting rod 18 passes through the vertical plate and is slidably installed with the vertical plate. The other end of the second connecting rod 18 is fixedly installed with the limiting plate 17. The limiting plate 17 is parallel to the reciprocating lead screw 8.

[0038] A second motor 16 is slidably mounted on one side of the limiting plate 17, and the output end of the second motor 16 is fitted with the top of the rotating roller 28. A second connecting seat 32 is slidably mounted on one side of the limiting plate 17 by snap-fit. A T-slot 21 is formed on one side of the limiting plate 17, and a T-block 23 is fixedly mounted on the side of the second connecting seat 32 facing the limiting plate 17. The T-block 23 is adapted to the T-slot 21, and the T-block 23 and the T-slot 21 are slidably fitted together.

[0039] A third slider 19 is slidably mounted on one side of the second connecting seat 32. A drive mechanism for moving the third slider 19 is mounted on the second connecting seat 32. The drive mechanism includes a third motor 31, which is fixedly mounted on the side of the second connecting seat 32 away from the limiting plate 17. A second groove is provided on the side of the second connecting seat 32 near the rotating roller 28, and the second groove is arranged along the length of the second connecting seat 32. A threaded rod 30 is rotatably mounted in the second groove. The output end of the third motor 31 passes through the second connecting seat 32 and is fixedly fitted with the threaded rod 30. The threaded rod 30 passes through the third slider 19 and is threadedly connected to the third slider 19. The third slider 19 is slidably fitted with the second groove.

[0040] A hinge seat 20 is hinged to the side of the third slider 19 near the rotating roller 28. The hinge seat 20 is L-shaped and is fixedly fitted with the second motor 16. The output end of the second motor 16 passes through the hinge seat 20 and extends to the bottom of the hinge seat 20. A movable shaft 26 is fixedly installed at the output end of the second motor 16.

[0041] A guide groove is provided at the top of the rotating roller 28, and the guide groove is aligned with the axis of the rotating roller 28. The cross-section of the guide groove is square. The movable shaft 26 is adapted to the guide groove, and is inserted into the guide groove and slidably installed with the guide groove to prevent relative rotation between the movable shaft 26 and the guide groove. A connecting block 22 is rotatably installed at the bottom of the rotating roller 28, and the connecting block 22 is hinged to the second slider 10.

[0042] Because some vehicles have a wider bottom and narrower top, the clean cylinder 29, when in a vertical position, adheres more closely to the lower part of the vehicle body, but less closely to the upper part, and may even fail to contact the upper part of the vehicle. Therefore, the tilt angle of the clean cylinder 29 can be adjusted by using a drive mechanism to regulate the degree of contact between the clean cylinder 29 and the upper and lower parts of the vehicle body.

[0043] A first slider 3 is slidably mounted on the upper surface of the base away from the stop block 9. The first slider 3 consists of a vertical rod and a horizontal rod, with the horizontal rod fixedly mounted on the top of the vertical rod. A movable groove 25 is provided on the top of the base, parallel to the first connecting seat 7, and the movable groove 25 is slidably engaged with the bottom of the vertical rod of the first slider 3. The horizontal rod of the first slider 3 is located above the first connecting seat 7, and a connecting rod 5 is hinged to the top of the horizontal rod of the first slider 3. The other end of the connecting rod 5 is hinged to the middle position of the first connecting rod 4, and the connecting rod 5 is arranged diagonally.

[0044] The crossbar of the first slider 3 cooperates with the second slider 10 and drives the first connecting rod 4 to move via the connecting rod 5. The movement of the first connecting rod 4 drives the first connecting seat 7 to move, and the movement of the first connecting seat 7 drives the second slider 10 to move. The movement of the first connecting rod 4 also drives the connecting rod 6 and the second connecting rod 18 to move. The movement of the second connecting rod 18 drives the limiting plate 17 to move, and the movement of the limiting plate 17 drives the second connecting seat 32 to move. The movement of the second connecting seat 32 drives the second motor 16 to move. Thus, under the synchronous movement of the second slider 10 and the limiting plate 17, the cleaning cylinder 29 moves towards the vehicle, increasing the adhesion between the cleaning cylinder 29 and the outer surface of the vehicle and improving the wiping effect of the cleaning cylinder 29 on the vehicle.

[0045] A fixing block 11 is symmetrically fixedly installed on the top of the horizontal plate. The fixing block 11 has a cavity inside. A positioning rod 12 is symmetrically installed in the cavity. The top end of the positioning rod 12 extends to the top of the fixing block 11 and is slidably installed with the fixing block 11. The bottom end of the positioning rod 12 extends to the bottom of the horizontal plate and is slidably installed with the horizontal plate.

[0046] A spring 24 is fitted onto the outer surface of the positioning rod 12, and the spring 24 is located inside the cavity. One end of the spring 24 is fixedly fitted with the fixing block 11. A fixing plate is fixedly fitted onto the outer surface of the positioning rod 12, and the fixing plate is located inside the cavity. The other end of the spring 24 is fixedly fitted with the fixing plate. In its natural state, the fixing plate is in contact with the upper surface of the horizontal plate, and the bottom end of the positioning rod 12 near the vertical plate is located in the limiting hole.

[0047] The top of the second connecting rod 18 is symmetrically provided with limiting holes, and the bottom of the positioning rod 12 is arc-shaped. The bottom of the positioning rod 12 slides with the corresponding limiting hole and positions the second connecting rod 18.

[0048] A stop block 9 is fixedly installed on one side of the top of the base. The side of the stop block 9 facing the first connecting seat 7 is stepped, and the connection between the steps is an arc-shaped surface. A top block 27 is fixedly installed on one side of the second slider 10. The top block 27 slides and engages with the side of the stop block 9 facing the first connecting seat 7, thereby driving the first connecting seat 7 to move towards the vertical plate.

[0049] The working principle of the reciprocating car wiping device provided by this invention is as follows:

[0050] In the initial state, the second slider 10 is located at one end of the first groove, and the top block 27 is in contact with the stop block 9.

[0051] In use, park the vehicle between the left and right connecting frames, ensuring the vehicle body is flush with the left-side cleanroom cylinder 29. Then, move the right-side connecting frame 2 by activating the hydraulic rod 13, thereby bringing the right-side cleanroom cylinder 29 into contact with the vehicle body.

[0052] Start the third motor 31, which drives the threaded rod 30 to rotate. The rotation of the threaded rod 30 drives the third slider 19 to move along the second slide groove. The third slider 19 drives the hinge seat 20 to move. The hinge seat 20 drives the second motor 16 to move. The second motor 16 drives the movable shaft 26 to move. The movable shaft 26 drives the rotating roller 28 to tilt.

[0053] As the movable shaft 26 drives the rotating roller 28 to tilt, the movable shaft 26 slides along the guide groove on the rotating roller 28. Since the hinge seat 20 is hinged to the third slider 19, and the bottom of the cleaning cylinder 29 is hinged to the second slider 10 via the connecting block 22, the rotating roller 28 can drive the cleaning cylinder 29 to tilt towards the vehicle body, adjusting the degree of contact between the cleaning cylinder 29 and the vehicle body. This improves the wiping effect of the cleaning cylinder 29 on the vehicle body.

[0054] The second motor 16 is started, driving the movable shaft 26 to rotate. The movable shaft 26 drives the rotating roller 28 to rotate, which in turn drives the cleaning cylinder 29 to rotate, thus wiping the car body. Then, the first motor 15 is started, driving the reciprocating screw 8 to rotate. The reciprocating screw 8 drives the second slider 10 to move along the first slide groove. At the same time, the movement of the second slider 10 drives the rotating roller 28 to move, which in turn drives the cleaning cylinder 29 to move. Thus, the cleaning cylinder 29 moves along the car body, performing the first wipe of the car body.

[0055] As the clean cylinder 29 moves, it drives the hinge seat 20 to move, which in turn drives the second connecting seat 32 to move. The movement of the second connecting seat 32 causes the T-shaped block 23 to slide along the T-shaped groove 21, thereby making the clean cylinder 29 more stable when it moves.

[0056] As the second slider 10 moves away from the baffle 9, it contacts the first slider 3 and drives the first slider 3 to move along the movable groove 25. When the first slider 3 moves, it drives the first connecting rod 4 and the second connecting rod 18 to move via the connecting rod 5. Simultaneously, the movement of the first connecting rod 4 and the second connecting rod 18 drives the first connecting seat 7 and the second connecting seat 32 to move. The synchronous movement of the first connecting seat 7 and the second connecting seat 32 drives the cleaning cylinder 29 towards the vehicle body, increasing the wiping force of the cleaning cylinder 29 on the vehicle body, thereby increasing the adhesion between the cleaning cylinder 29 and the vehicle body and improving the wiping effect of the cleaning cylinder 29 on the vehicle body.

[0057] Meanwhile, as the second connecting rod 18 moves toward the vehicle body, the bottom end of the positioning rod 12 near the vertical plate first disengages from the limiting hole of the second connecting rod 18, and then the bottom end of the positioning rod 12 away from the vertical plate slides into the limiting hole and positions the second connecting rod 18, preventing the clean cylinder 29 from moving toward the vertical plate due to the reaction force of the vehicle body, thereby avoiding a reduction in the squeezing force of the clean cylinder 29 on the vehicle body.

[0058] Then, the cleaning cylinder 29 moves in the opposite direction under the action of the reciprocating screw 8, performing a second wipe on the car body. Due to the increased contact between the cleaning cylinder 29 and the car body, the second wipe of the car body by the cleaning cylinder 29 further improves the wiping effect of the cleaning cylinder 29 on the car body compared to the first wipe.

[0059] During the reverse movement of the clean cylinder 29, when the second slider 10 drives the top block 27 to contact the stop block 9, the top block 27 and the stop block 9 slide against the side of the vertical plate, thereby causing the first connecting seat 7 to move toward the vertical plate.

[0060] The first connecting seat 7 moves, which in turn drives the second connecting rod 18 to move via the first connecting rod 4. The movement of the second connecting rod 18 causes the limiting hole to move toward the vertical plate, so that the bottom end of the positioning rod 12, which is close to the vertical plate, slides into the limiting hole under the action of the spring 24, thus positioning the second connecting rod 18.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
