Description

Technical Field

[0001] This application relates to the field of fully automatic car wash technology, specifically a non-contact spray cleaning automatic car wash machine for automobiles. Background Technology

[0002] Automatic car wash machines are devices that are controlled by computer programs and combine sensors, high-pressure water guns, brushes, foam spraying devices and other equipment to automatically complete the work of washing, waxing and drying vehicles. They can significantly improve car wash efficiency, reduce labor costs, and provide more standardized and consistent car wash services. For example, patent CN221068028U discloses a gantry reciprocating brush car wash machine, including a base plate with a frame on top. The frame houses two vertical brush mechanisms, a horizontal brush mechanism, and a rinsing and drying mechanism. Each vertical brush mechanism includes a first motor, a bidirectional threaded rod, two first sliders, two limiting blocks, two vertical brush assemblies, and two wheel brush assemblies. The first motor is fixedly mounted on one outer wall of the frame. The bidirectional threaded rod is rotatably mounted inside the frame, with one end fixedly connected to the output shaft of the first motor. Both first sliders are threaded onto the bidirectional threaded rod, and the two limiting blocks are fixedly mounted on the tops of the two first sliders. This gantry reciprocating brush car wash machine can automatically clean the sides and top of vehicles, offering the advantages of fast and comprehensive cleaning. The aforementioned patent requires the use of brushes to remove dirt, mud, and dust from the vehicle's surface during cleaning. However, the frequent contact between the brushes and the vehicle body during this cleaning process may cause scratches and damage due to brush wear. For vehicles with high requirements for paint protection, this could not only reduce the lifespan of the paint but also potentially lead to unnecessary disputes. Therefore, it is necessary to provide a non-contact spray cleaning automatic car wash machine to solve the above problems.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Example 1 This embodiment mainly illustrates the basic structure and principle of the non-contact spray cleaning automatic car wash machine, specifically: like Figures 2-3 As shown, this application provides a non-contact spray cleaning automatic car wash machine for automobiles, including a support mechanism 1 for supporting the vehicle to be cleaned. The support mechanism 1 includes a support platform 11, which is generally erected on the ground. Two sets of vehicle tracks 12 are provided on the support platform 11, with a certain distance between the two sets of vehicle tracks 12 to adapt to the distance between the left and right wheels of the vehicle. Both ends of the vehicle tracks 12 are provided with ramps 13 to guide the vehicle, so that the vehicle can enter the vehicle track 12 along the ramps 13 and travel on the vehicle track 12 to the designated cleaning position. In this embodiment, the width of the vehicle track 12 is set to be relatively wide, so as to adapt to vehicles with different wheelbases, and the vehicle can travel more smoothly on the vehicle track 12. It should be noted that the support platform 11 is erected on the ground by a support rod or a pad, so that there is a gap between the bottom of the support platform 11 and the ground (not shown in the figure). A water collection box (not shown in the figure) is installed in the gap, and a through-hole (not shown in the figure) is provided on the support platform 11, so that the wastewater from the subsequent vehicle washing can enter the water collection box for collection through the water hole. like Figures 2-5 As shown, a vehicle body washing mechanism 2 is provided at the upper end of the support platform 11. The vehicle body washing mechanism 2 includes four sets of columns 21 fixedly installed on the support platform 11. At the same time, a crossbeam (not shown in the figure) is fixedly installed at the upper end of the four sets of columns 21. A reinforcing beam 23 is provided between the crossbeam and the columns 21, so that the columns 21, the crossbeam and the reinforcing beam 23 form a stable frame structure. Meanwhile, a cleaning rail 22 is fixedly installed on the crossbeam along the vehicle's direction of travel. A cleaning robot 3 is installed on the cleaning rail 22. The cleaning robot 3 includes a cleaning cart 31. In order for the cleaning cart 31 to move on the cleaning rail 22, extension arms 311 are provided on both sides of the cleaning cart 31. Rollers (not shown in the figure) are provided on the extension arms 311. A wheel rail 210 is provided on the cleaning rail 22, so that the rollers can roll along the wheel rail 210 to drive the cleaning cart 31 to move along the vehicle's direction of travel. In order to drive the cleaning truck 31 to move, such as Figures 2-5 As shown, a drive mechanism is provided on the cleaning rail 22. The drive mechanism includes a first motor 24 fixedly installed at one end of the cleaning rail 22, a first sprocket 25 fixedly installed at the output end of the first motor 24, and a support plate 27 fixedly installed at the other end of the cleaning rail 22. A support shaft 28 is fixedly installed on the support plate 27, and a second sprocket 29 is mounted on the support shaft 28. A chain 26 is provided between the second sprocket 29 and the first sprocket 25 for transmission. Thus, under the drive of the first motor 24, the chain 26 is continuously driven by the continuous rotation of the first sprocket 25. Meanwhile, a connecting plate (not shown in the figure) is fixedly installed on the cleaning vehicle 31. The connecting plate is fixedly installed on the chain 26, so that when the chain 26 is continuously driven, the cleaning vehicle 31 can be moved along the vehicle's direction of travel through the connecting plate. In order to spray and clean the vehicle, such as Figure 3 and Figures 6-7 As shown, a water pump 32 is installed on the support platform 11. The input end of the water pump 32 is connected to an external water pipe. At the same time, a cavity (not shown in the figure) is provided inside the cleaning vehicle 31. The cavity is connected to the output end of the water pump 32 by a connecting pipe 33. Thus, the cleaning water in the external water pipe can be introduced into the cavity of the cleaning vehicle 31 through the water pump 32. Meanwhile, cleaning pipes 34 are provided at both ends of the cleaning vehicle 31. The cleaning pipes 34 are connected to the cavity. Multiple sets of nozzles 35 are evenly arranged on the cleaning pipes 34, so that the cleaning water in the cavity can flow through the cleaning pipes 34 and be sprayed out through the nozzles 35. The cleaning pipe 34 is arranged in an arc along the side of the vehicle. Specifically, the cleaning pipe 34 has a horizontally arranged first section, which is mainly used for spraying the top of the vehicle. At the same time, a vertical second section is arranged at the lower end of the first section, which is mainly used for spraying the side of the vehicle. An arc-shaped third section is arranged between the first and second sections, which is mainly used for spraying the connection between the top of the vehicle and the arc of the side. In summary, when the vehicle needs to be cleaned, the vehicle is driven along track 12 into the interior of the frame structure and then stopped. Then, the water pump 32 is turned on to introduce cleaning water into the cavity of the cleaning vehicle 31 and spray it onto the vehicle through the nozzle 35. During the process of spraying and cleaning the vehicle, the first motor 24 drives the cleaning vehicle 31 to move along the length of the vehicle so that the cleaning water sprayed by the nozzle 35 can cover the entire vehicle. This achieves the effect of pressurizing the water through the water pump 32 and then spraying the water at high speed onto the surface of the vehicle through the nozzle 35, using the impact force of the water flow to remove dirt, mud and dust from the surface of the vehicle.

[0023] Furthermore, such as Figure 2 As shown, a control box 14 is installed on one side column 21. The control box 14 is equipped with a PLC control system, which is used to control the coordinated operation of various electrical components in this application. At the same time, buttons are provided on the control box 14 for easy operation by the staff, so that the staff can control the vehicle washing process through the buttons.

[0024] In order to clean the front and rear of the vehicle, such as Figure 2 and Figures 6-7 As shown, a rotating mechanism 4 is provided on the first section of the cleaning pipe 34. The rotating mechanism 4 includes a second motor 42 fixedly installed at the lower end of the cleaning cart 31. An extension rod 43 is fixedly installed at the output end of the second motor 42. The bottom of the extension rod 43 is provided with a thread 44. Meanwhile, a clamping ring is fitted on the first section of the cleaning tube 34. The clamping ring has a first clamping arc 41 and a second clamping arc 45 that cooperate with each other. The first clamping arc 41 and the second clamping arc 45 are provided with matching holes, so that the extension rod 43 is suitable to pass through the holes and the thread 44 is located at the lower end of the clamping ring. Furthermore, a nut 46 is installed on the thread 44 of the extension rod 43, so that the clamping ring not only clamps the first section of the cleaning tube 34 through the thread 44, but also fixes the clamping ring to the extension rod 43, so that when the second motor 42 works, it can drive the cleaning tube 34 to rotate synchronously. It should be noted that the cleaning pipe 34 and the cleaning cart 31 are connected by a rotary seal. For the specific structure, please refer to the existing relevant patents. It will not be elaborated in this embodiment. In this embodiment, a position sensor can be installed on the cleaning pipe 34 to collect the spray position in real time, thereby controlling the movement of the cleaning vehicle 31. In summary, when the cleaning pipe 34 moves to the front or rear of the vehicle, the second motor 42 controls the two sets of cleaning pipes 34 to rotate synchronously, so that the cleaning pipe 34 rotates to the front or rear of the vehicle. At this time, the nozzle 35 is facing the vehicle, and the front or rear of the vehicle can be sprayed and cleaned.

[0025] To remove the washing water sprayed on the vehicle, such as Figure 6 As shown, multiple sets of brackets 36 are installed on the upper part of the cleaning vehicle 31. A fan 37 is installed on the bracket 36. The air outlet of the fan 37 faces the vehicle, so that the airflow can be blown towards the vehicle to dry the vehicle.

[0026] Example 2 While cleaning the vehicle body is common, tires accumulate a lot of dust and impurities due to long-term driving, especially vehicles driven on mountain roads where a lot of mud and sand can accumulate. If the tires are not cleaned, even if the vehicle body is cleaned, the mud and sand on the tires will splash onto the vehicle body during subsequent driving. While painted areas such as car bodies may suffer scratches and damage due to brush wear, tires do not require consideration of wear during cleaning. Therefore, this application provides the following tire cleaning solution: like Figure 3 and Figure 8 As shown, multiple sets of water collection mechanisms 5 are provided on the track 12 along the direction of vehicle travel. Each water collection mechanism 5 has a water collection trough 51 located at the bottom of the wheel. When washing the vehicle body, the water collection trough 51 collects the cleaning water to prevent the cleaning water from flowing freely. Meanwhile, a water outlet (not shown in the figure) is provided at the bottom of the water collection tank 51. The water outlet is located at the top of the water collection box, so that the water entering the water collection tank 51 can enter the water collection box through the water outlet to prevent the cleaning water from overflowing from the top of the water collection tank 51. like Figures 8-11 As shown, a wheel cleaning mechanism 6 is provided in the water collection tank 51. The wheel cleaning mechanism 6 includes a base plate 61 fixedly installed at the bottom of the water collection tank 51. A rotating plate 65 is provided at the upper end of the base plate 61. A third motor 66 is fixedly installed on the rotating plate 65. A rotating shaft 68 is fixedly installed at the output end of the third motor 66. A cleaning blade 67 is fixedly installed on the rotating shaft 68. The uppermost end of the cleaning blade 67 is slightly lower than the upper end surface of the water collection tank 51. Therefore, when the vehicle's tire is located at the upper end of the water collection tank 51, the lowest point of the tire will be lower than the upper end surface of the water collection tank 51 and will be disengaged from the cleaning blade 67. At this time, the third motor 66 is started to drive the cleaning blade 67 to rotate, thereby cleaning the vehicle's tire. In this embodiment, a wheel cleaning mechanism 6 is provided in each of the multiple sets of water collection tanks 51. In order to cover the cleaning of the entire wheel, the distance between the multiple sets of water collection tanks 51 can be increased at equal intervals, or they can be divided into several groups, with each group cleaning a specific angle position of the tire, thereby achieving the purpose of full coverage. Furthermore, such as Figure 10As shown, the cleaning blade 67 includes multiple sets of horizontal plates 671 fixedly installed along the circumference of the rotation axis 68. Multiple sets of contact teeth 672 are evenly arranged on the horizontal plates 671. Adjacent contact teeth 672 and the horizontal plates 671 form a sludge collection trough 673. The contact teeth 672 contact the tire, scraping off the mud and impurities on the tire and dropping them into the sludge collection trough 673. As the cleaning blade 67 rotates, when the sludge collection trough 673 is at its lowest point, the mud and impurities in the sludge collection trough 673 will fall to the bottom of the water collection trough 51 due to gravity.

[0027] Furthermore, in order to accommodate tires of different sizes, the position of the washing blade 67 is adjustable, specifically: like Figure 11 As shown, a second support plate 64 is fixedly installed on the base plate 61, and the bottom of the rotating plate 65 is rotatably installed on the second support plate 64. A first support plate 62 is fixedly installed on the base plate 61, and a hydraulic cylinder 63 is hinged to the first support plate 62. The output end of the hydraulic cylinder 63 is hinged to the rotating plate 65, so that when the output end of the hydraulic cylinder 63 extends or retracts, it can drive the rotating plate 65 to rotate, thereby changing the position of the cleaning blade 67 to adapt to the cleaning of tires of different sizes.

[0028] In order to clean the cleaning blade 67, a certain level of stagnant water is required in the water collection tank 51. At the same time, the stagnant water needs to be changed frequently to prevent the cleaning blade 67 from being contaminated again. To solve the above problems, such as Figure 9 As shown, a spring 56 is fixedly installed inside the water collection tank 51. A rack 54 is fixedly installed at the other end of the spring 56. A sealing strip 55 is fixedly installed at the lower end of the rack 54. The size of the sealing strip 55 is adapted to the water outlet at the bottom of the water collection tank 51. Thus, in the initial state, due to the action of the spring 56, the sealing strip 55 covers the upper end of the water outlet and closes the water outlet. At this time, the water collection tank 51 can accumulate a certain amount of stagnant water. It should be noted that the side of the rack 54 is provided with a groove, and the side of the water collection tank 51 is provided with a boss (not shown in the figure) adapted to the groove. Thus, the rack 54 is suitable for moving along the axial direction of the spring 56. Meanwhile, a disc 52 is fixedly installed at one end of the rotating shaft 68. A meshing tooth 53 is provided at a localized position on the circumference of the disc 52. This meshing tooth 53 can mesh with the rack 54, allowing the disc 52 to rotate synchronously with the rotating shaft 68, and the meshing tooth 53 and rack 54 to mesh intermittently. When the meshing tooth 53 meshes with the rack 54, it will drive the rack 54 to move, which in turn will drive the sealing strip 55 to move and open the outlet so that the stagnant water can flow out. When the meshing teeth 53 disengage from the rack 54, the sealing strip 55 will reset under the action of the spring 56 and block the water outlet. In this embodiment, the number of meshing teeth 53 is small, so the meshing teeth 53 and the rack 54 are in a disengaged state most of the time, thereby allowing a certain amount of stagnant water to be stored in the water collection tank 51.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
