Description

Technical Field

[0001] This utility model relates to the field of vehicle cleaning technology, and more specifically, to a cleaning device for vehicles. Background Technology

[0002] In the existing technological field, automated cleaning devices for vehicles have been widely used. Traditional vehicle cleaning processes usually follow a set sequence: First, specially formulated cleaning foam is evenly sprayed onto the vehicle surface, allowing it to fully contact the dirt and react chemically. Then, high-pressure water is used to thoroughly rinse the vehicle, completely removing loose dirt and residual foam. Next, the system automatically delivers high-speed drying airflow to initially blow away water stains from the vehicle surface, reducing residual water. Finally, precisely designed wiping rollers and highly absorbent cloths are used to meticulously wipe the vehicle body, ensuring the surface is shiny and new.

[0003] However, a thorough analysis of existing technologies reveals significant shortcomings in the fluid control system design of most vehicle cleaning devices currently on the market. Whether it's the foam delivery system, the high-pressure water jetting device, or the high-speed airflow conveying mechanism for the drying stage, the flow rate parameters are almost always designed to be constant, lacking necessary adjustment capabilities. This rigid design philosophy fails to meet the diverse cleaning needs of different vehicle models, paint materials, levels of contamination, and ambient temperatures during actual use. This results in an inability to achieve an optimal balance between cleaning effectiveness and energy efficiency. Specifically, when dealing with the high-gloss paint of luxury cars, excessive water flow impact can cause minor scratches; while for stubborn dirt on the surface of off-road vehicles, the standard flow rate is insufficient to thoroughly remove mud and oil. Similarly, in cold seasons, a fixed flow rate for drying air cannot effectively address the reduced evaporation rate of moisture in low-temperature environments. This technical deficiency, the inability to adapt the delivery flow rate to actual usage needs, negatively impacts cleaning quality and user experience.

[0004] Secondly, while some improved vehicle cleaning equipment does exist on the market, its designers achieve dynamic adjustment of the conveying flow rate through simple combinations of components. However, these devices generally suffer from insufficient engineering considerations in their structural design. The adjustment mechanisms are simplistic and crude, and their stability and reliability indicators fail to meet application standards. During long-term operation, these devices often experience loosening and displacement of carefully adjusted components due to complex fluid dynamics effects such as water hammer, pressure fluctuations, and resonance caused by the flow of liquids or gases within the pipeline. This is especially true under the combined influence of pressure shocks generated during the start-up and shutdown of the cleaning pump, as well as external factors such as motor vibration. The stability of the adjustment mechanism's parameters is difficult to guarantee. This technical defect of insufficient structural stability directly leads to unpredictable fluctuations and drifts in the adjusted conveying flow rate parameters during actual use, resulting in random variations in cleaning effects. For cleaning services of high-end vehicles, such uncontrollable fluctuations in cleaning parameters pose serious quality risks and potential customer complaints, ultimately affecting the market reputation and promotion of automated vehicle cleaning equipment and hindering the overall improvement of the industry's technological level.

[0011] The present invention is further configured such that a liquid flow pipe is detachably provided inside the mounting bracket, and a plurality of first nozzles are provided on one side of the liquid flow pipe. A mixing tank is detachably provided on one side of the water pump. One end of the mixing tank is connected to the output end of the water pump through a delivery pipe, and the output end of the mixing tank is connected to the control sleeve through a delivery pipe. The input end of the liquid flow pipe is connected to the corresponding connecting pipe. This structural design realizes the uniform delivery of cleaning liquid and clean water. The reasonable layout of the multiple first nozzles ensures that the cleaning foam can be sprayed all over the vehicle body surface, greatly improving the cleaning efficiency and the thoroughness of dirt removal.

[0012] The present invention is further configured such that an airflow pipe is detachably provided on the inner side of the mounting frame, and a plurality of second nozzles are provided on one side of the airflow pipe. The input end of the airflow pipe is connected to one of the connecting pipes. This design achieves precise separation of the drying process and the cleaning process through an independent airflow pipe and a dedicated second nozzle system, ensuring the stability of the drying airflow.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cleaning device for vehicles, which has the following beneficial effects:

[0018] 1. Through the ingenious design and organic coordination of key components such as the control sleeve, adjusting plate, sliding shaft, rotating shaft, sliding groove, and adjusting hole, the technical shortcoming of fixed flow rate in existing technologies has been successfully solved. This structural design allows operators to flexibly adjust the delivery speed of cleaning foam, high-pressure water, and drying air according to the actual needs of different vehicle models, paint materials, and levels of contamination, achieving precise control of the cleaning process. Specifically, by rotating the control sleeve to move the adjusting plate, the movement of the adjusting hole on the adjusting plate and the movement of the adjusting plate itself can change the flow area inside the delivery pipe, thereby precisely adjusting the fluid flow speed. This flexible and adjustable design concept enables the device to reduce the water flow impact to avoid minor scratches on the high-gloss paint of luxury cars, while also increasing the cleaning power to thoroughly remove mud and oil stains from the surface of off-road vehicles. It can also adjust the drying air speed according to seasonal temperature changes to adapt to the moisture evaporation rate requirements in different environments, significantly improving cleaning quality and user experience, and achieving the best balance between cleaning effect and energy utilization efficiency.

[0019] 2. Through the precise coordination of meticulously designed components such as the shift sleeve, switching rod, switching spring, shift frame, shift rod, shift plate, shift spring, and shift groove, the technical defects of the existing technology, such as simple structure and insufficient stability, are effectively solved. This innovative structure achieves a reliable locking function after adjustment, ensuring that the adjusted components will not loosen or shift due to complex fluid dynamics such as water hammer effect, pressure fluctuation, and resonance phenomenon inside the pipeline during long-term operation. Specifically, after the flow rate adjustment is completed, the shift spring pushes the shift plate to drive the shift rod into the corresponding shift groove. The shift sleeve is released, the switching spring resets, disengaging the switching rod from the switching hole, and then the switch is rotated. The plate replacement causes the switching rod and switching hole to misalign, ultimately limiting the position of the shifting sleeve on the shifting plate. Multiple locking mechanisms work together to ensure that the shifting frame and control sleeve will not rotate unexpectedly. This highly reliable locking system can effectively resist the pressure shock generated during the start-up and shutdown of the cleaning pump and the influence of external factors such as motor vibration. It ensures that the adjusted conveying flow rate parameters remain stable during actual use, avoiding random changes in cleaning effect. In particular, it provides quality assurance for cleaning services of high-end vehicles, eliminates potential customer complaints, improves the market reputation and application prospects of automated vehicle cleaning equipment, and makes a positive contribution to the overall improvement of the industry's technical level.

[0030] A mounting bracket 19 is detachably mounted on one side of the water pump 1 and the air pump 2. A first lead screw 20 and a second lead screw 21 are rotatably mounted in the mounting bracket 19. The second lead screw 21 is mounted on the top of the mounting bracket 19, and the first lead screw 20 is mounted on one side of the mounting bracket 19. Multiple cleaning rollers 22 are detachably mounted inside the mounting bracket 19. Movable frames 23 are detachably mounted on one side of each cleaning roller 22. A drive motor 24 is detachably mounted on the movable frame 23. The output end of the drive motor 24 is connected to one end of the cleaning roller 22. One movable frame 23 is movably connected to the first lead screw 20 by a thread. The other two movable frames 23 are movably connected to the corresponding second lead screw 21. There are two symmetrical second lead screws 21, and the threads of the two second lead screws 21 are opposite to each other. A movable motor 25 is detachably mounted on the top of the mounting bracket 19. The two ends of the movable motor 25 are connected to one end of the two second lead screws 21 respectively. A lifting motor 26 is detachably mounted on one side of the mounting bracket 19. The output end of the lifting motor 26 is connected to the top of the first lead screw 20.

[0031] The mounting bracket 19 is equipped with detachable sliding rods 27 on the top and both sides, and the movable bracket 23 is slidably connected to the sliding rods 27.

[0032] The mounting bracket 19 has a detachable liquid flow pipe 28 on its inner side. Multiple first nozzles 29 are provided on one side of the liquid flow pipe 28. A mixing tank 30 is detachably provided on one side of the water pump 1. One end of the mixing tank 30 is connected to the output end of the water pump 1 through the delivery pipe 3.

[0034] A conveyor 33 is detachably provided on the bottom inner side of the mounting frame 19, a wiping cloth 34 is detachably provided on the inner side of the mounting frame 19, and a wiping roller 35 is detachably provided on one side of the wiping cloth 34.

[0035] In this embodiment, when the device is needed, the vehicle is first driven onto the conveyor 33, then put in neutral and fold the rearview mirrors. The conveyor 33 is then turned on, causing it to move the vehicle forward gradually. The water pump 1 is then turned on, drawing water from an external source through the delivery pipe 3 connected to its input end. This water is then delivered to the delivery pipe 3 connected to the output end of the pump. The clean water is then delivered to the mixing tank 30 through one of the delivery pipes 3, where it mixes with the cleaning solution inside the mixing tank 30 to form foam. The foam is then released through the output end of the mixing tank 30. The connected delivery pipe 3 delivers the cleaning foam to the first liquid flow pipe 28, and then multiple first nozzles 29 spray the cleaning foam onto the outside of the vehicle. Then, the moving motor 25 is activated, causing two second lead screws 21 to rotate synchronously. This causes the corresponding two movable frames 23 to move inward along the slide rod 27, bringing the two longitudinally arranged cleaning rollers 22 into contact with the sides of the vehicle. Simultaneously, the drive motor 24 mounted on the movable frame 23 is activated, causing the two longitudinally arranged cleaning rollers 22 to rotate, thus cleaning the sides of the vehicle. When the lifting motor 26 is turned on, it drives the first lead screw 20 to rotate, causing the other movable frame 23 to lift the horizontally arranged cleaning roller 22. Simultaneously, the drive motor 24 installed on one side of this movable frame 23 is turned on, driving the cleaning roller 22 to rotate, thus wiping the vehicle's surface. Then, another delivery pipe 3 connected to the output end of the water pump 1 delivers clean water through the connecting pipe 5 to the second liquid flow pipe 28. This causes multiple first nozzles 29 on one side of the second liquid flow pipe 28 to spray clean water, rinsing off the foam. Turn on air pump 2, which draws in filtered clean air and compresses it. Then, through the delivery pipe 3 connected to the output end, the compressed gas is delivered to the airflow pipe 31 via the connecting pipe 5. The clean gas is then blown out through multiple nozzles on one side of the airflow pipe 31, thereby initially removing and drying the water stains on the vehicle's exterior surface. The vehicle then passes through a wiping cloth 34, which wipes and absorbs the water stains on the vehicle's surface. Finally, the vehicle passes through two wiping rollers 35, which wipe and absorb the water stains on both sides of the vehicle, achieving a thorough cleaning of the vehicle.

[0036] Please see Figures 3-5 As a further implementation of the overall equipment: the adjustment plate 10 is provided with multiple adjustment holes 36.

[0037] One end of the sliding shaft 11 is slidably positioned in the sliding groove 18, and one end of the rotating shaft 12 is rotatably connected to the inner wall of the control sleeve 4.

[0038] More specifically, when it is necessary to adjust the flow rate of gas and liquid transport, firstly, rotate the switching plate 50 so that the switching plate 50 drives the switching hole 6 to rotate to the position corresponding to the switching rod 8. Then, push the shift sleeve 7, which will drive one side of the switching rod 8 to pass into the switching hole 6. The shift sleeve 7 will cooperate with the switching plate 50 to squeeze the switching spring 9, so that the shift sleeve 7 no longer limits the outer wall of the shift plate 16. Then, rotate the control sleeve 4 in the forward direction. The control sleeve 4 will drive one side of the shift frame 14 to rotate in the forward direction. Then, the shift frame 14 will drive the shift rod 15, the shift spring 17, and the shift plate 16 to rotate in the forward direction. Then, the shift groove... The inner wall of the 13 presses against one end of the displacement rod 15. Due to the rounded corner design of the inner wall edge of the displacement groove 13 and one end of the displacement rod 15, one end of the displacement rod 15 slides out of the displacement groove 13, and the other end of the displacement rod 15 is stretched outward by the displacement plate 16 driving the displacement spring 17. At the same time, the control sleeve 4 drives the inner adjusting plate 10 to move through the rotating shaft 12, so that the adjusting plate 10 drives the sliding shaft 11 on the other side to spread outward along the sliding groove 18, so that the adjusting plate 10 spreads outward and drives the adjusting hole 36 to move. The movement of the adjusting hole 36, in conjunction with the spreading movement of the adjusting plate 10, changes the... The internal flow area of ​​the conveying pipe 3 is changed, thereby altering the fluid flow rate. Once a suitable conveying flow rate is achieved, the control sleeve 4 is stopped from rotating, causing the shifting frame 14 to rotate the shifting rod 15 and other components to the position corresponding to the shifting groove 13. Then, the shifting spring 17 resets and pulls the shifting plate 16, causing the shifting plate 16 to slide the shifting rod 15 inward, inserting one end of the shifting rod 15 into the corresponding shifting groove 13. Then, the shifting sleeve 7 is released, and the switching spring 9 pushes the shifting sleeve 7 to slide reset. The shifting sleeve 7 then drives one side of the switching rod 8 to slide reset. After the switching spring 9 is fully reset, the switching rod 8 no longer penetrates the switching hole. In step 6, the switching plate 50 is rotated again, causing the switching hole 6 to rotate to a position that does not correspond to the switching rod 8. Then, the switching rod 8 limits and supports the shift sleeve 7 to one side of the switching plate 50, so that the shift sleeve 7 will not slide easily. Then, the inner wall of the shift sleeve 7 limits the outer wall of the shift plate 16, so that the shift plate 16 and the shift rod 15 cannot slide outward. Then, the shift rod 15 and the shift groove 13 cooperate to lock the shift frame 14, so that the shift frame 14 and the control sleeve 4 will not rotate accidentally, thereby ensuring the structural stability after the conveying flow rate is adjusted, ensuring the stable delivery of fluid, and thus ensuring the stable operation of cleaning work.

[0039] In summary, the overall equipment is used or operated as follows: When the equipment needs to be used, first drive the vehicle onto the conveyor 33, then put it in neutral and fold the rearview mirrors. Then turn on the conveyor 33, allowing it to gradually move the vehicle forward. Next, turn on the water pump 1. The water pump 1 draws water from the external source through the conveying pipe 3 connected to its input end and delivers it to the conveying pipe 3 connected to its output end. Then, through one of the conveying pipes 3, the clean water is delivered to the mixing tank 30, where it mixes with the cleaning liquid inside the mixing tank 30 to form foam. Then, the foam is released through the mixing tank. The output end of the 30 is connected to the delivery pipe 3, which delivers the liquid to the first liquid pipe 28. Then, the cleaning foam is sprayed onto the outside of the vehicle through multiple first nozzles 29. Then, the moving motor 25 is turned on, which drives the two second lead screws 21 to rotate synchronously, causing the corresponding two movable frames 23 to move inward along the slide bar 27, so that the two longitudinally arranged cleaning rollers 22 are in contact with the sides of the vehicle. At the same time, the drive motor 24 installed on the movable frame 23 is turned on, which drives the two longitudinally arranged cleaning rollers 22 to rotate, thereby wiping the sides of the vehicle. The system washes the surface of the vehicle, then turns on the lifting motor 26. The lifting motor 26 drives the first lead screw 20 to rotate, causing another movable frame 23 to lift the horizontally positioned cleaning roller 22. Simultaneously, the drive motor 24 installed on one side of this movable frame 23 is turned on, driving the cleaning roller 22 to rotate, thus wiping the vehicle's surface. Then, another delivery pipe 3 connected to the output end of the water pump 1 delivers clean water through the connecting pipe 5 to the second liquid flow pipe 28. This causes multiple first nozzles 29 on one side of the second liquid flow pipe 28 to spray clean water, rinsing away the foam. Then, the air pump 2 is turned on, and the air pump 2 draws in the filtered clean air and compresses it. Then, the compressed gas is delivered to the airflow pipe 31 through the connecting pipe 5 via the delivery pipe 3 connected to the output end. Then, the clean gas is blown out through multiple nozzles set on one side of the airflow pipe 31, thereby preliminarily treating and removing water stains on the vehicle's exterior surface and preliminarily drying it. Then, the vehicle passes through the wiping cloth 34, which wipes and absorbs the water stains on the vehicle's upper surface. Then, the vehicle passes through two wiping rollers 35, which wipe and absorb the water stains on both sides of the vehicle, achieving a thorough cleaning of the vehicle.

[0040] When the flow rate of gas and liquid needs to be adjusted, first rotate the switching plate 50, causing the switching hole 6 to rotate to the position corresponding to the switching rod 8. Then push the shift sleeve 7, which will cause one side of the switching rod 8 to pass into the switching hole 6. The shift sleeve 7 and the switching plate 50 will also work together to compress the switching spring 9, so that the shift sleeve 7 no longer limits the outer wall of the shift plate 16. Then rotate the control sleeve 4 in the forward direction, which will cause one side of the shift frame 14 to rotate in the forward direction. Then the shift frame 14 will cause the shift rod 15, the shift spring 17, and the shift plate 16 to rotate in the forward direction. Then the inner wall of the shift groove 13 will rotate in the forward direction. When one end of the shift rod 15 is pressed, due to the rounded corner design of the inner wall edge of the shift groove 13 and one end of the shift rod 15, one end of the shift rod 15 slides out of the shift groove 13, and the other end of the shift rod 15 is stretched outward by the shift plate 16 driving the shift spring 17. At the same time, the control sleeve 4 drives the inner adjusting plate 10 to move through the rotating shaft 12, so that the adjusting plate 10 drives the sliding shaft 11 on the other side to spread outward along the sliding groove 18, so that the adjusting plate 10 spreads outward and drives the adjusting hole 36 to move. The movement of the adjusting hole 36, in conjunction with the spreading movement of the adjusting plate 10, changes the... The internal flow area of ​​the conveying pipe 3 changes the fluid flow rate. When the appropriate conveying flow rate is adjusted, the control sleeve 4 is stopped from rotating, and the shifting frame 14 drives the shifting rod 15 and other components to rotate to the position corresponding to the shifting groove 13. Then, the shifting spring 17 returns to its original position and pulls the shifting plate 16. The shifting plate 16 drives the shifting rod 15 to slide inward, so that one end of the shifting rod 15 is inserted into the corresponding shifting groove 13. Then, the shifting sleeve 7 is released, and the switching spring 9 pushes the shifting sleeve 7 to slide back to its original position. Then, the shifting sleeve 7 drives the switching rod 8 on one side to slide back to its original position. When the switching spring 9 is fully reset, the switching rod 8 no longer passes through the switching hole 6. Then, the switching plate 50 is rotated again, causing the switching plate 50 to rotate the switching hole 6 to a position that does not correspond to the switching rod 8. Then, the switching rod 8 limits and supports the shift sleeve 7 to one side of the switching plate 50, so that the shift sleeve 7 will not slide easily. Then, the inner wall of the shift sleeve 7 limits the outer wall of the shift plate 16, so that the shift plate 16 and the shift rod 15 cannot slide outward. Then, the shift rod 15 and the shift groove 13 cooperate to lock the shift frame 14, so that the shift frame 14 and the control sleeve 4 will not rotate accidentally, thereby ensuring the structural stability after the conveying flow rate is adjusted, ensuring the stable delivery of fluid, and thus ensuring the stable operation of cleaning work.
