Description

Technical Field

[0001] This invention relates to the field of car washing, and more specifically, to a hanging high-precision CNC contour washing device. Background Technology

[0002] Traditional fully automatic car wash machines rely on photoelectric, pressure, or current sensing to control the brushes' contact with the vehicle body. This traditional method requires manual supervision, increasing costs and wasting manpower. Furthermore, it cannot automatically identify the vehicle's model and cannot accurately recognize accessories such as antennas, bumpers, spare tires, spoilers, rearview mirrors, and tire size and position. This prevents it from intelligently avoiding these accessories while precisely cleaning the body and wheels, resulting in blind spots and potential damage to the vehicle. Summary of the Invention

[0038] The workflow of the car wash device proposed in this embodiment is as follows:

[0039] The vehicle is parked under the device frame 1. The laser radar scans the three-dimensional data parameters of the vehicle relative to the car wash machine 2. The car wash machine 2 uses this as the control device to clean the vehicle body. Specifically, the servo motor reducer drives the car wash machine 2 to move back and forth along the large trolley frame 31. The lateral servo motor drives the car wash machine 2 to move left and right along the small trolley frame 32. The screw structure drives the top cleaning brush 41 to move closer to the vehicle. Motor A drives the top cleaning brush 41 to rotate, and the top cleaning brush 41 cleans the top surface of the vehicle. Motor B drives the side cleaning brush 42 to rotate, and the side cleaning brush 42 cleans the front and rear of the vehicle in a circumferential manner, and the sides are fully covered by a wrap-around cleaning method.

[0040] During the cleaning process, water flows through pipe 51 to the top cleaning brush 41 and the side cleaning brush 42. Three forms of liquid can be sprayed out by adjusting valve 53 and foaming device: water, a mixture of cleaning solution and cleaning solution foam. The water pump delivers water into the interior of pipe 51, and the water can be sprayed directly onto the top cleaning brush 41 and the side cleaning brush 42 through pipe 51. When valve 53 is opened, the cleaning agent enters the interior of pipe 51 through inlet pipe 52 and merges with the water flow. The water flow drives the fan blade 63 to rotate, and the fan blade 63 drives the stirring blade 62 to rotate through the rotating shaft 61. When the stirring blade 62 rotates, it can mix water and cleaning solution together. The mixed cleaning solution and water can flow out together through pipe 51.

[0041] When cleaning agent foam needs to be sprayed, cylinder 81 is connected to an external power source. Cylinder 81 drives rack 82 to move up and down. Rack 82 and toothed ring 83 mesh, causing toothed ring 83 to rotate back and forth. Since toothed ring 83 and cylinder 89 are fixedly connected, toothed ring 83 can drive cylinder 89 to rotate back and forth. When cylinder 89 rotates back and forth, it can drive baffle 78 to swing back and forth around the axis of water pipe 71. When baffle 78 swings, it intersects with the through hole 77 opened on sealing plate A, so that water can flow through the through hole 77 to the bottom of water pipe 71.

[0042] It should be noted that in the initial state, the baffle plate 78 completely blocks the through hole 77, and the water flows through and out of the water pipe 71. When it is necessary to switch to the foam spraying state, the cylinder 81 drives the rack 82 to move downward, and the rack 82 drives the elastic telescopic rod 98 to move synchronously. The rack 82 and the elastic telescopic rod 98 descend synchronously for the first stage, driving the closing plate 99 to cover the opening of the water pipe 71. The rack 82 and the toothed ring 83 engage in the second stage, and the elastic telescopic rod 98 can maintain the closing plate 99 covering the opening of the water pipe 71.

[0043] When water flows below water pipe 71, sponge A 74 absorbs the mixture. It's important to note that when water flows into fitting 51, because fitting 51 is horizontally positioned, the water flow is relatively small. The lower half of sponge A 74 is submerged in water, while the upper half extends above the surface. Simultaneously, the cylinder 89 moves the toothed gear 84 synchronously. As the toothed gear 84 moves, it contacts the connecting rod 87 and pushes it downwards. At this time, the connecting rod 87 moves outwards inside the sleeve 85, pushing the filter plate 8... 8. The sponge A 74 is squeezed. When the connecting rod 87 moves to the position between the two sets of teeth 84, under the elastic force of the spring 86, the spring 86 pulls the connecting rod 87 to move upward, so that the filter plate 88 can move away from the sponge A 74. By reciprocating rotation of the cylinder 89, the filter plate 88 is adjusted to reciprocate up and down, so that the sponge A 74 is repeatedly pressed and released. Since the lower half of the sponge A 74 is in the mixture and the upper half of the sponge A 74 extends out of the mixture, the upper half of the sponge A 74 is filled with air.

[0044] During the pressing process of sponge A 74, the air inside flows upward and is discharged from sponge A 74, or flows downward. Because there are many tiny and interconnected pores in the sponge, the downward flowing air and the flowing liquid mixture are constantly in contact and mixed with each other during the pressing process of sponge A 74, so as to generate bubbles. As sponge A 74 is pressed to its limit, the bubbles generated inside it are discharged from sponge A 74. Since the density of the bubbles is less than that of the liquid mixture, the bubbles will float on the liquid mixture and continuously disperse and fill the collection chamber.

[0045] As the filter plate 88 rises, sponge A 74 returns to its original shape. The lower half of sponge A 74 reabsorbs the mixture, while the upper half absorbs air and some bubbles. As sponge A 74 is continuously pressed and restored, the purpose of rapidly generating bubbles is achieved.

[0046] At this point, the bubbles are relatively large and are partially mixed with the liquid.

[0047] This allows Sponge A 74 to reabsorb water and detergent, and by repeating the above actions, Sponge A 74 can squeeze water and detergent into detergent foam.

[0048] While the cylinder 89 is rotating back and forth, the cylinder 89 drives the two A baffles 72 to swing back and forth around the water pipe 71. When one A baffle 72 swings up, the other A baffle 72 swings down. The swinging A baffle 72 can squeeze the B sponge 75, and the swinging A baffle 72 drives the B sponge 75 to return to its original state.

[0049] During the downward swing of the A baffle 72, the trigger 94 contacts the opening and closing plate 91, and the trigger 94 pushes the opening and closing plate 91 to rotate around the hinge axis 92, thereby opening the opening and closing plate 91. At this time, since the collection chamber is filled with air bubbles, as the A baffle 72 continues to swing downward, the air bubbles can enter the extrusion chamber. Moreover, when the A baffle 72 swings downward, the corresponding B sponge 75 inside it is in the recovery action, so the B sponge 75 can suck in the air bubbles.

[0050] After the A baffle 72 swings down, it swings up again, pressing the B sponge 75. At this time, some air bubbles will be discharged from the squeezing chamber. As it disengages from the trigger 94, the opening and closing plate 91 closes, thus closing the squeezing chamber. After the squeezing chamber is closed, the electric push rod 95 pushes the B sealing plate 96 away from the filter screen 97, thus connecting the squeezing chamber and the discharge chamber. As the A baffle 72 continues to swing up, the B sponge 75 is continuously squeezed. At this time, since most of the air bubbles absorbed by the B sponge 75 are concentrated in its lower half, and the upper half of the B sponge 75 contains air, when it is squeezed, the air bubbles inside the B sponge 75 flow upward with the air again. Air bubbles with higher water content will come into contact with the air again and continuously generate air bubbles. Moreover, larger air bubbles will be continuously broken down into smaller air bubbles. As the B sponge 75 is squeezed, these fine and dense foams will be discharged into the discharge chamber, which will then discharge the foam inside.

[0051] Through the above steps, the mixture is first continuously mixed and contacted with air to create bubbles with a high water content and large volume. Then, the bubbles are mixed with air again to divide their volume, thereby achieving the purpose of creating fine and dense foam.

[0052] The foam squeezed out by sponge A 74 can be absorbed by sponge B 75. As sponge B 75 moves from baffle A 72 to baffle B 73, baffle A 72 and baffle B 73 can squeeze sponge B 75. At the same time, electric push rod 95 pushes sealing plate B 96 away from filter screen 97. The foam squeezed out by sponge B 75 can enter between baffle B 73 and pipe 51 through filter screen 97. When baffle A 72 moves away from baffle B 73, air can enter the interior of pipe 51 through pressure valve. At the same time, electric push rod 95 drives sealing plate B 96 to reset. Sealing plate B 96 blocks filter screen 97 again. The two sponges B 75 repeat the above actions, so that the foam between baffle B 73 and pipe 51 increases, thereby squeezing the foam out of the interior of pipe 51.

[0053] Through the above actions, this invention can achieve truly safe, unattended, and intelligent car washing. It can automatically identify existing car models and accurately identify vehicle accessories such as antennas, bumpers, spare tires, spoilers, rearview mirrors, and tire size and position.
