Description

Technical Field

[0001] The present invention relates to the technical field of vehicle maintenance, and in particular to an automatic car washing machine with uniform force. Background Art

[0002] A car wash machine is a machine that uses computer-controlled brushes and high-pressure water to automatically clean cars. By setting the brush to travel a fixed stroke and spraying detergent on the vehicle surface, the vehicle surface can be automatically cleaned.

[0003] Chinese patent CN 109484366 B discloses a convenient self-service smart car wash platform, including a car wash execution device, one side of which is respectively provided with a solar panel, a water tank and a car wash liquid storage tank. The car wash execution device includes a spray rod mechanism that can reciprocate above the vehicle body, and one end of the spray rod mechanism that passes through the screw nut is provided with a medium switching mechanism that can be connected to the water tank and the car wash liquid storage tank respectively; the car wash execution device also includes an elastic rubber shaft that can be fitted with the vehicle body, both ends of the elastic rubber shaft are connected to the rail trolley through a universal coupling, one end of the elastic rubber shaft is provided with a transmission motor for driving the shaft to rotate, and the elastic rubber shaft located on the top of the vehicle body is fixedly connected to the spray rod mechanism through a cylinder.

[0004] However, although this technical solution can achieve cleaning of the vehicle surface, it cannot meet the requirements of accurate brushing intensity for the side surfaces of vehicles of different models, resulting in inconsistent cleaning intensity of stains on the vehicle surface. Moreover, when cleaning the vehicle, the detergent is often sprayed first and then brushed. The detergent falls too quickly, resulting in excessive accumulation on the lower half of the vehicle, resulting in poor cleaning effect. Moreover, since the detergent is sprayed for too long, it falls under the action of gravity and falls off the vehicle surface, resulting in waste of detergent. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology and provide an automatic car washing machine with uniform force. The machine reaches the rearview mirrors on both sides of the vehicle through the mirror isolation assembly to isolate and clean the mirror body. At the same time, a smooth moving surface of the positioning assembly is built, and the protective partition moves and sticks to the vehicle surface after isolation by the mirror isolation assembly. The positioning assembly is positioned to the surface of the protective partition and is transmitted to the side cleaning part to reach the specified distance on the other side of the vehicle, so that the spray assembly above the obliquely arranged cleaning belt sprays detergent on the vehicle, and the moving bristles quickly process the detergent falling from each layer on the vehicle surface. The drainage assembly continuously drains the stains absorbed by the bristles, and then the driving part switches the positioning part to rotate, so that the side cleaning part cleans the other side of the vehicle under the positioning action of the positioning part, and cleans the front, rear and roof of the vehicle in turn through the end cleaning part and the top cleaning part, so as to solve the technical problems mentioned in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An automatic car washing machine with uniform force includes a washing tank, and is characterized in that it also includes: a driving part, which is installed on the top of the washing tank; a positioning part, which is installed on one side of the driving part for positioning one side of the vehicle in sequence along the height direction; a side washing part, which is obliquely distributed layer by layer along the height direction of the vehicle and is transmission-connected to the positioning part; and an end washing part, which is installed on the side walls of the washing tank respectively for washing the front side and the rear side of the vehicle; the driving part drives the positioning part and the side washing part to move back and forth synchronously along the length direction and the height direction of the vehicle and to rotate with the center of the vehicle as the origin.

[0008] Furthermore, the positioning part includes: a vehicle mirror isolation assembly, two groups of which are symmetrically arranged and used to be mounted on the vehicle mirror for isolation and cleaning; a protective spacer, the protective spacer is provided on one side of the vehicle mirror isolation assembly for moving the cover toward the side of the vehicle on which the vehicle mirror isolation assembly is mounted; and a positioning assembly, the positioning assembly is provided on one side of the protective spacer for positioning the side of the vehicle at various height positions along the surface of the protective spacer.

[0009] Furthermore, the protective spacer includes: a spacer whose length and width dimensions are respectively greater than the length and height of the vehicle, and the spacer is a component made of elastic material; and a pushing member, which drives the spacer to stick to one side of the vehicle and the pushing member is arranged on both sides of the spacer.

[0010] Furthermore, the positioning assembly includes: a transmission seat; a transmission assembly installed on the transmission seat; a contact piece elastically passing through the transmission seat and connected to the transmission assembly; and a pushing piece, wherein the pushing piece is provided on the transmission seat for pushing the contact piece away from the side of the vehicle; the other end of the transmission assembly is connected to the side washing part.

[0011] Furthermore, the positioning portion further includes: a spraying component installed on the driving portion and used for flushing the inner surface of the upwardly moving protective partition.

[0012] Furthermore, the vehicle mirror isolation assembly includes: a cover shell, the cover shell being in elastic contact with the vehicle surface and arranged along the vehicle height direction; a vehicle mirror cleaning nozzle provided on the top of the cover shell; and a moving assembly driving the cover shell to move toward one side of the vehicle mirror.

[0013] Furthermore, the side cleaning part includes: a cleaning seat; a driving and rotating assembly, which is installed on the cleaning seat; a cleaning belt, the cleaning belt having bristles evenly arranged on the surface is transmission-connected to the driving and rotating assembly; a liquid spraying assembly, which is arranged on the upper side of the obliquely arranged cleaning belt; and a liquid drainage assembly, which is installed on the cleaning seat and pressed on the cleaning belt away from the vehicle surface.

[0014] Furthermore, the driving assembly includes: a driving roller, which is a conical structure with a radial size that continuously decreases from the middle to both ends; and a power member, which is drivingly connected to the driving roller.

[0015] Furthermore, the drainage assembly includes: a power pusher; and an extrusion member installed on the power end of the power pusher, and the extrusion member is a columnar structure.

[0016] Furthermore, the car washing machine also includes: a top cleaning component installed on one side of the rear end of the positioning part for moving the roller brush up and down on the roof.

[0017] The beneficial effects of the present invention are:

[0018] (1) The present invention uses the mutual cooperation between the positioning part and the side cleaning part to enable the positioning part to simulate the bending change of one side of the vehicle in the height direction during cleaning to realize the cleaning positioning of the other side of the vehicle through the side cleaning part, so that the cleaning intensity of the adjusted side cleaning part is more uniform and accurate when cleaning the vehicle surface, thereby achieving a higher consistency in the vehicle surface treatment effect;

[0019] (2) The present invention achieves the positioning between the rearview mirror position and the side surface of the vehicle by establishing an isolation and cleaning channel for the vehicle rearview mirror through the mutual cooperation between the vehicle mirror isolation component, the protective component and the positioning component. This solves the problem of the positioning component directly contacting the vehicle surface and causing scratches under the protection of the protective component, and also solves the problem of the rearview mirror affecting the positioning component's positioning query of the side surface of the vehicle in the rearview mirror area.

[0020] (3) The present invention adopts the oblique arrangement design of the cleaning belt and the interaction between the cleaning belt and the liquid spraying assembly. When the liquid spraying assembly located obliquely above the cleaning belt sprays the cleaning agent, the moving cleaning belt can quickly process the cleaning agent at each height layer in sequence, thereby solving the technical problem of uneven distribution of the cleaning agent in each height direction due to the sliding of the cleaning agent;

[0021] (4) The present invention uses the interaction between the drainage component and the cleaning belt. When the cleaned bristles reach one side of the extrusion part, the bristles are squeezed out, so that the stains adsorbed in the bristles are discharged and the vehicle surface is treated again, thereby ensuring the cleanliness of the vehicle surface after treatment.

[0022] (5) The present invention utilizes the interaction between the protective spacer and the spray cleaning assembly. When the protective spacer is placed on one side of the vehicle and the positioning surface is switched, the spray cleaning assembly sprays and cleans the surface of the protective spacer during the rising process, thereby preventing the surface of the protective spacer from remaining on the vehicle surface and adhering to the cleaned surface on the other side of the vehicle.

[0023] In summary, the present invention has the advantages of high detergent utilization rate during vehicle cleaning, uniform scrubbing force on the side surface of the vehicle, good scrubbing effect, etc. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0037] Example 1

[0038] like Figure 1 As shown, an automatic car washing machine with uniform force includes a washing tank 1, and also includes: a driving part 2, which is installed on the top of the washing tank 1; a positioning part 3, which is installed on one side of the driving part 2 for positioning one side of the vehicle in sequence along the height direction; a side washing part 4, which is obliquely distributed layer by layer along the height direction of the vehicle and is transmission-connected with the positioning part 3; and an end washing part 5, which is installed on the side wall of the washing tank 1 for washing the front side and the rear side of the vehicle; the driving part 2 drives the positioning part 3 and the side washing part 4 to move back and forth synchronously along the length direction and the height direction of the vehicle and rotate with the center of the vehicle as the origin.

[0039] From the above content, it is not difficult to find that when cleaning a vehicle, the vehicle surface is often cleaned by spraying detergent on the vehicle and then using a cleaning brush. However, after the detergent is sprayed on the vehicle, the detergent will continue to roll down under the action of gravity, forming a situation where there is more detergent in the lower layer and less detergent in the upper layer. In addition, some detergent will roll off the sprayed surface of the vehicle, resulting in a waste of detergent. Moreover, in the process of washing the vehicle surface, due to the different types of vehicles, the curvature of the two sides of the vehicle is different. Therefore, when cleaning both sides of the vehicle, a brush roller arranged vertically along the height direction of the vehicle is often used for processing. This method is not convenient for providing uniform force to the vehicle surface, resulting in different treatment intensity at different parts of the vehicle surface, and even technical problems such as some positions being difficult to clean.

[0040] In an embodiment of the present invention, the vehicle is positioned along a fixed linear path and driven into the cleaning warehouse 1 (this part can be achieved by using a specific linear track to limit the movement of the tires or other existing technical methods), the driving unit 2 will drive the positioning unit 3 to reach one side of the vehicle for positioning processing, and after the positioning unit 3 completes the positioning of one side of the vehicle, the side cleaning unit 4 will complete the positioning of the other side of the vehicle, so that the side cleaning unit 4 can, under the positioning transmission of the positioning unit 3, complete the position adjustment of the corresponding side of the vehicle according to the positioning result of the other side of the vehicle by the positioning unit 3, so that the side cleaning unit 4 can be better adjusted to complete the cleaning action at the same or similar distance as the vehicle surface during cleaning, thereby ensuring the uniformity of the cleaning intensity of the vehicle surface, and after the cleaning of one side of the vehicle is completed, the driving unit 2 will drive the positioning unit 3 and the side cleaning unit 4 to switch the positioning of the other side of the vehicle, and when switching, the end cleaning unit 5 will clean both ends of the vehicle.

[0041] It is worth noting that when the vehicle surface is cleaned by using the obliquely arranged side cleaning part 4, the side cleaning part 4 will spray the cleaning liquid obliquely upward, and at the same time, the cleaning liquid that falls to each height is processed separately on the vehicle surface by the obliquely arranged side cleaning part 4, thereby solving the problem of not being able to uniformly clean the vehicle at different heights due to the cleaning liquid falling under the action of gravity.

[0042] It should be added that, Figure 2 As shown, the end cleaning portion 5 includes an end cleaning seat 51, an end cleaning roller 52 installed at the bottom of the end cleaning seat 51, a pushing motor 53 connected to one side of the end cleaning seat 51, a guide seat 54 installed on the side wall of the cleaning reservoir 1 and slidably inserted with the pushing motor 53, a pulling motor 55 installed on the cleaning reservoir 1 and connected to the pushing motor 53 at the power end, and an end cleaning rotating motor 56 installed on the end cleaning seat 51 and connected to the end cleaning roller 52 at the power end.

[0043] In this embodiment, the pulling motor 55, which is preferably a push rod motor, drives the end cleaning roller 52 to move back and forth to adjust the distance between it and the front or rear of the vehicle, so that the end cleaning rotating motor 56, which is preferably a servo motor, drives the end cleaning roller 52 to rotate, and under the power of the pushing motor 53, which is preferably a push rod motor, it moves back and forth along the width direction of the front or rear of the vehicle to complete the cleaning action.

[0044] It is also necessary to add that Figure 3 and 4 As shown, the driving part 2 includes a crossbeam 21 installed on the top of the cleaning library 1, a driving rotary motor 22 installed on the crossbeam 21, a mobile frame 23 installed on the power end of the driving rotary motor 22, a driving screw rod 24 installed in the mobile frame 23, a moving block 25 threadedly connected to the driving screw rod 24, and a lifting motor 26 installed on the moving block 25 and the power end of which is connected to the positioning part 3.

[0045] In this embodiment, when the positioning part 3 needs to be raised or lowered to replace the vehicle positioning cleaning side, the driving screw 24 is first driven to rotate by preferably a servo motor, thereby driving the moving block 25 to move to the middle position on the driving screw 24, and then the positioning part 3 is driven upward to above the vehicle by the lifting motor 26, which is preferably a push rod motor, and then the moving frame 23 is driven to rotate by the driving rotating motor 22, which is preferably a servo motor, so that the positioning part 3 and the side cleaning part 4 change positions.

[0046] like Figure 3 As shown, the positioning part 3 includes: a vehicle mirror isolation component 31, and the vehicle mirror isolation component 31 used for isolating and cleaning is symmetrically arranged in two groups; a protective spacer 32, the protective spacer 32 is provided on one side of the vehicle mirror isolation component 31 for moving the cover toward the side of the vehicle on which the vehicle mirror isolation component 31 is provided; and a positioning component 33, the positioning component 33 is provided on one side of the protective spacer 32 for positioning the side of the vehicle at various height positions along the surface of the protective spacer 32.

[0047] In this embodiment, when the positioning portion 3 performs positioning processing on one side of the vehicle, the vehicle mirror isolation component 31 is used to preferentially cover the vehicle rearview mirror, thereby solving the problem that the positioning component 33 cannot move smoothly along the vehicle surface due to interference from the rearview mirror, and the rearview mirror is easily damaged. During the movement and positioning of the positioning component 33, the anti-slip part 32 is used to protect the vehicle surface, thereby solving the problem of vehicle scratches caused by direct contact between the positioning component 33 and the vehicle.

[0048] like Figure 3 and 6As shown, the protective spacer 32 includes: a spacer 321 whose length and width dimensions are respectively greater than the length and height of the vehicle, and the spacer 321 is a component made of elastic material; and a pushing member 322, which drives the spacer 321 to stick to one side of the vehicle. The pushing member 322 is arranged on both sides of the spacer 321.

[0049] In this embodiment, during the process of the protective spacer 32 providing protection between the vehicle and the positioning assembly 33, the spacer 321 is pushed onto the side wall of the vehicle after the mirror isolation assembly 31 is positioned by utilizing the power of the pushing member 322, so that the spacer 321 can be tightly attached to the side wall of the vehicle, thereby ensuring the accuracy of subsequent positioning using the positioning assembly 33 and solving the problem of scratches caused by the positioning assembly 33 directly contacting the side wall of the vehicle.

[0050] It should be added that, Figure 3 As shown, in order to realize the reciprocating movement of the spacer 321 on one side of the vehicle, the pushing member 322 includes a pushing seat 3221 and a pushing motor 3222 whose power end is connected to the pushing seat 3221. The pushing motor 3222 is preferably a servo motor.

[0051] like Figure 4 As shown, the positioning assembly 33 includes: a transmission seat 331; a transmission assembly 332 installed on the transmission seat 331; a contact member 333 elastically passing through the transmission seat 331 and connected to the transmission assembly 332; and a pushing member 334, the pushing member 334 for pushing the contact member 333 away from the side of the vehicle is arranged on the transmission seat 331; the other end of the transmission assembly 332 is connected to the side cleaning part 4.

[0052] In this embodiment, when the positioning component 33 transmits the positioning information of one side of the vehicle to the side cleaning part 4 on the other side, it uses the contact piece 333 elastically connected to the transmission seat 331 to elastically press on the side wall of the vehicle, and through the transmission action of the transmission component 332, it further drives the side cleaning part 4 to make corresponding position adjustments on the other side of the vehicle. Subsequently, the cleaning position of the side cleaning part 4 will continue to follow the position movement of the contact piece 333 on the vehicle and continuously adjust, thereby ensuring the accuracy of the cleaning position of the side cleaning part 4.

[0053] It should be added that, Figure 7As shown, in order to ensure that the transmission assembly 332 transmits power accurately to the opposite side cleaning part 4, the transmission assembly 332 includes a fixed shaft 3321 installed on the transmission seat 331, a transmission gear 3322 rotatably sleeved on the fixed shaft 3321, a first rack 3323 engaged on one side of the transmission gear 3322 and connected to the contact member 333, and a second rack 3324 engaged on the other side of the transmission gear 3322 and connected to the side cleaning part 4.

[0054] It is also necessary to add that Figure 6 As shown, in order to ensure the smooth movement of the contact member 333 on the vehicle surface, the contact member 333 includes a transmission rod 3331 one end of which passes through the transmission seat 331 and is connected to the first rack 3323, a resistance spring 3333 elastically connecting the transmission rod 3331 and the transmission seat 331, and a contact roller 3332 installed on the transmission rod 3331.

[0055] Then, as Figure 7 As shown, in order to ensure that all the first racks 3323 and the contact members 333 are pushed to one side at the same time, the pushing member 334 includes a pushing seat 3341 and a pushing motor 3342 whose power end is connected to the pushing seat 3341. The push rod motor 3342 is preferably a push rod motor.

[0056] like Figure 4 As shown, the positioning portion 3 further includes: a spray assembly 34 installed on the driving portion 2 and used for flushing the inner surface of the protective partition 32 moving upward.

[0057] In this embodiment, the spray components 34 are symmetrically arranged into two groups along the length direction of the protective partition 32. Therefore, during the rising process of the protective partition 32, not only can the spraying work be carried out by utilizing the spray components 34, but the positioning part 3 can also be driven by the driving part 2 to move between the spray components 34 before spraying, thereby solving the problem of movement interference during the spraying process.

[0058] like Figure 11 As shown, the vehicle mirror isolation assembly 31 includes: a cover shell 311, the cover shell 311 elastically contacting the vehicle surface is arranged along the vehicle height direction; a vehicle mirror cleaning nozzle 312 provided on the top of the cover shell 311; and a moving assembly 313 driving the cover shell 311 to move toward one side of the vehicle mirror.

[0059] In this embodiment, the cover 311 with a soft end surface is mounted on the rearview mirror and is in close contact with the side surface of the vehicle under the power of a moving component 313 which is preferably a push rod motor. As a result, under the top-down spraying action of the mirror cleaning nozzle 312, the guide surface space of the driving part 2 formed by the cover 311 is self-cleaned.

[0060] like Figure 1 As shown, the car washing machine further includes: a top cleaning assembly 6 installed on one side of the rear end of the positioning part 3 for moving the roller brush up and down on the roof.

[0061] In this embodiment, when the positioning part 3 and the side washing part 4 move to clean both sides of the vehicle respectively, the top washing part 6 will perform cleaning after the positioning part 3 and the side washing part 4 move, thereby ensuring that the top of the vehicle is clean after cleaning.

[0062] It should be added that, Figure 5 As shown, in order to better achieve the cleaning treatment of the top of the vehicle, the top cleaning part 6 includes a top cleaning roller 61 installed on one side of the transmission seat 331 and a top nozzle 62 provided at the moving front end of the top cleaning roller 61 and evenly arranged along the width direction of the vehicle; it should also be added that in order to achieve the adaptive position adjustment of the top cleaning roller 61 to the top surface of the vehicle, the transmission seat 331 is also equipped with a top lifting motor for driving the top cleaning roller 61 to move up and down, and the top lifting motor is preferably a push rod motor.

[0063] Example 2

[0064] like Figure 8 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0065] The side cleaning portion 4 includes: a cleaning seat 41; a driving assembly 42, which is installed on the cleaning seat 41; a cleaning belt 43, the cleaning belt 43 having bristles 431 evenly arranged on the surface of which is transmission-connected to the driving assembly 42; a liquid spraying assembly 44, which is arranged on the obliquely upper side of the obliquely arranged cleaning belt 43; and a liquid draining assembly 45, which is installed on the cleaning seat 41 and pressed on the cleaning belt 43 away from the vehicle surface.

[0066] In this embodiment, when the side washing portion 4 moves in the positioning guide direction of the positioning portion 3, the driving action of the driving component 42 causes the cleaning belt 43 arranged obliquely on the cleaning seat 41 to rotate, and when the cleaning belt 43 rotates, the bristles 431 will continuously perform a rotational cleaning and brushing treatment on the vehicle surface, and during the rotational cleaning, the drainage component 45 will spray the cleaning agent on the vehicle surface obliquely above the obliquely arranged cleaning belt 43, and after spraying, the cleaning agent is quickly brushed on the vehicle surface by the moving bristles 431, thereby achieving the goal of cleaning the vehicle while saving the cleaning agent.

[0067] It is worth noting that in order to more effectively reduce the falling speed of the detergent and further save the amount of detergent used, the spray volume per unit time of the spray component 44 can be adjusted. At the same time, the bristles 431 are arranged in a spiral shape on the cleaning belt 43, so that the bristles 431 carry the detergent upward in a spiral manner while rotating, thereby reducing the falling time of the detergent and increasing the processing time of the detergent.

[0068] like Figure 9 As shown, the driving assembly 42 includes: a driving roller 421, which is a conical structure with a radial size continuously decreasing from the middle to both ends; and a power member 422, which is transmission-connected to the driving roller 421.

[0069] In this embodiment, when the driving assembly 42 drives the cleaning belt 43 to rotate, the driving roller 421 is driven to rotate by the power member 422, so that the cleaning belt 43 sleeved on the driving roller 421 rotates.

[0070] It is worth noting that by utilizing the conical driving roller 421, the cleaning belt 43 can be driven by the driving unit 2 to move back and forth in a small range up and down to clean stains on the surface of the vehicle back and forth along the height direction of the vehicle, such as stain particles with a greater adsorption force combined with the vehicle along the height direction of the vehicle.

[0071] It should be added that, Figure 10 As shown, in order to realize the driving rotation of the driving roller 421 by the power member 422, the power member 422 includes a first gear 4221 installed on the driving roller 421, a second gear 4222 engaged on one side of the first gear 4221, and a third gear 4223 engaged on one side of the second gear 4222, and a power motor 4224 installed on the cleaning seat 41 and the power end connected to the third gear 4223. The power motor 4224 is preferably a servo motor.

[0072] like Figure 8 As shown, the liquid discharge assembly 45 includes: a power pusher 451; and an extrusion member 452 installed on the power end of the power pusher 451, and the extrusion member 452 is a columnar structure.

[0073] In this embodiment, when the drainage component 45 processes the cleaning liquid adsorbed by the bristles 431, the power pusher 451, which is preferably a push rod motor, drives the extrusion member 452 to press on the bristles 431 on one side of the cleaning belt 43, thereby squeezing the bristles 431 and squeezing out the detergent adsorbed on the bristles 431. This solves the problem that the bristles 431 that continue to brush are in a saturated state due to adsorbing a large amount of stained detergent and are unable to complete the absorption of the newly sprayed detergent and effectively treat the vehicle surface.

[0074] Working steps

[0075] Step 1: Isolate the rearview mirrors. The mirror isolation assembly 31 is positioned on the rearview mirrors on both sides of the vehicle to cover them. Then, the protective spacer 32 is placed under the mirror isolation assembly 31 and pressed against the surface of one side of the vehicle, serving as a guide contact surface for the positioning assembly 33.

[0076] Step 2: Positioning and cleaning: one end of the contact member 333 is in contact with the protective partition 32 close to the vehicle surface due to the elastic force of the contact member 333, and the side cleaning portion 4 is adjusted to the other side of the vehicle through the transmission action of the transmission assembly 332. Then, the driving unit 2 drives the contact member 333 to move, and the side cleaning portion 4 also moves back and forth along the width direction of the vehicle to adjust the corresponding position, and cleans the surface of the other side of the vehicle through the side cleaning portion 4;

[0077] Step 3: Cleaning and brushing. The spray assembly 44 above the inclined cleaning belt 43 sprays detergent toward the vehicle surface. The detergent falls within the range of the cleaning belts 43 arranged at different heights. The moving bristles 431 carry the detergent toward the vehicle surface to form friction, carrying away the stains on the vehicle surface. After cleaning, the drain assembly 45 drains the bristles that have been cleaned, so that the empty bristles reach the vehicle surface and absorb the detergent again to clean the vehicle surface.

[0078] Step 4: Switching to vehicle cleaning: the driving unit 2 drives the positioning unit 3 that has finished cleaning one side to move upward to the top of the vehicle. During the movement, the spray cleaning assembly 34 sprays and cleans the surface as the spacer 321 moves upward. Subsequently, the driving unit 2 drives the positioning unit 3 and the side cleaning unit 4 to swap positions on both sides of the vehicle and clean the other side of the vehicle again;

[0079] Step 5: Top surface cleaning: when the positioning unit 3 follows the driving unit 2 to move and clean, the top cleaning component 6 will clean the roof of the vehicle;

[0080] Step 6: Cleaning the front and rear of the vehicle. The end cleaning unit 5 moves to a designated distance between the front and rear of the vehicle, and cleans the front and rear of the vehicle along the width direction.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
