[0031] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0032] like Figure 1-9 As shown, the present invention provides a trackless tunnel car washing machine, including a frame 1, the length, width and height dimensions of the frame 1 are: 8000*3900*3150mm, the frame 1 is the main structure of the entire car washing machine, and its two ends are respectively a vehicle entrance and a vehicle exit. The frame 1 provides installation support for other components to ensure that each component can operate stably. Warning signs 6 are respectively installed at the entrance and exit of the frame 1 to remind vehicle drivers to pay attention to safety and avoid accidents such as collisions.

[0033] Cleaning parts

[0034] Horizontal brush: A horizontal brush 3 is installed on the frame 1. The horizontal brush 3 is mainly used to clean the top and sides of the vehicle. The horizontal brush 3 is driven by the first driving mechanism 7 and can be adjusted up and down according to the height and position of the vehicle to achieve effective cleaning of different models.

[0035] Brush mechanism: The brush mechanism 4 is installed on the frame 1 and is used for cleaning the sides and front and rear parts of the vehicle. The brush mechanism 4 includes a left front brush 41, a right front brush 42, a left rear brush 43 and a right rear brush 44. The central positions of the four brushes are arranged in a parallelogram, and the four brushes are driven by the second driving mechanism 8 to work. This layout can make the brushes better fit the side curve of the vehicle and improve the cleaning effect.

[0036] High-pressure water jet: High-pressure water jets 12 are installed on the left and right sides of the second fixing frame 11 and on the top crossbeam at the entrance of the frame 1. The high-pressure water jets 12 can perform preliminary high-pressure washing on the surface of the vehicle when the vehicle enters the car washing machine, remove most of the dust and dirt on the surface of the vehicle, and prepare for subsequent cleaning work.

[0037] Drive adjustment mechanism

[0038] First driving mechanism: The first driving mechanism 7 is installed on the second fixed frame 11, and is used for driving and adjusting the position of the horizontal brush 3. The first driving mechanism 7 includes a first cylinder 73 and two first swing rods 74 installed on the second fixed frame 11. The output end of the first cylinder 73 is hinged with a first swing rod 74, and a first motor 71 is installed on the first swing rod. The output end of the first motor 71 is installed with a first mounting shaft 72, and the horizontal brush 3 is installed on the first mounting shaft 72. Positioning rods 75 are installed on both sides of one end of the frame 1. One side of the top of the two first swing rods 74 is rotatably connected to the positioning rod 75. Connecting rods 76 are respectively installed on the two first swing rods 74, and the two connecting rods 76 are connected via a cross rod 77. When the first cylinder 73 is extended or retracted, the first swing rod 74 is driven to rotate around the positioning rod 75, thereby realizing the up and down position adjustment of the horizontal brush 3. At the same time, the first motor 71 drives the first mounting shaft 72 to rotate, so that the horizontal brush 3 rotates for cleaning.

[0039] Second driving mechanism: The second driving mechanism 8 is installed on the two first fixing frames 10, and is used to adjust the position of the brush holding mechanism 4. The second driving mechanism 8 includes two second cylinders 81 respectively installed on both sides of the first fixing frame 10 and two rotating rods 82 rotatably connected to both sides of the first fixing frame 10. The upper and lower sides of the outer surface of the rotating rod 82 are respectively fixed with tripods 83, and the ends of the tripods 83 away from the rotating rod 82 are respectively fixed with second swing rods 84. The upper surfaces of the second swing rods 84 away from the ends of the rotating rods 82 are respectively rotatably connected with second mounting shafts 85. A second motor is installed on the second mounting shaft 85, and the brush holding mechanism is installed on the second mounting shaft 85. The output end of the second cylinder 81 is hinged with the second swing rod 84. When the second cylinder 81 is extended or retracted, the second swing rod 84 is pushed to rotate around the rotating rod 82, thereby realizing the opening and closing action of the brush holding mechanism 4 to adapt to vehicles of different widths. The second motor drives the second mounting shaft 85 to rotate, so that the brush holding mechanism rotates for cleaning operations.

[0040] Optimized structure of the second swing arm: a guide rod 87 is installed on one end of the second swing arm 84 close to the first fixed frame 10, and an arc guide rail 86 adapted to the guide rod 87 is fixed to the first fixed frame 10. The guide rod 87 slides in the arc guide rail 86, which can ensure that the movement of the second swing arm 84 is more stable and accurate, and improve the working reliability of the brush holding mechanism 4. In addition, the second swing arm 84 is a hollow structure, and a support rod 13 is installed at the center position of the opposite side of the two second swing arms 84. The support rod 13 is installed with a water pipe 14, the transportation part of the water pipe 14 is installed in the second swing arm 84, and the water spraying part of the water pipe 14 is installed on the outer surface of the support rod 13. The water spraying part of the water pipe 14 is installed with a nozzle 15 for discharging water. This structural design makes the arrangement of the water pipe 14 more reasonable and avoids interference with the water pipe during movement. At the same time, the nozzle 15 can spray water on the surface of the vehicle to cooperate with the brush for cleaning.

[0041] Hair dryer

[0042] The blower mechanism 9 is installed at one end of the vehicle exit of the frame 1 and is used to blow dry the water on the vehicle body. The blower mechanism 9 includes a plurality of third motors 91 installed on the upper cross beam at the vehicle exit of the frame 1. A blower 92 is installed at the output end of the third motor 91. When the vehicle is cleaned and passes through the vehicle exit, the third motor 91 drives the blower 92 to rotate at a high speed, generating a strong wind force to blow dry the moisture on the surface of the vehicle body.

[0043] Guide mechanism

[0044] The guide mechanism 5 is located directly below the frame 1 and fixed to the ground, and is used for the correct entry and exit of the vehicle. The guide mechanism 5 includes two symmetrical guide rods 51 installed on one side of the ground at the entrance of the frame 1. The ends of the two guide rods 51 are respectively provided with anti-deflection rods 52, and the guide rods 51 and the anti-deflection rods 52 are arranged in a Y shape. The guide rods 51 and the anti-deflection rods 52 are both fixed to the ground. Fixed plates 54 are evenly installed on the other side directly below the frame 1. The fixed plates 54 are fixed to the ground, and guide steel bars 53 are installed on the fixed plates 54. The wheels on the left and right sides of the car are respectively placed in the lanes surrounded by the guide rods 51 and the anti-deflection rods 52 and on the guide steel bars 53. In this way, the vehicle can be guided accurately into the car washing machine to avoid vehicle deviation and ensure the smooth progress of the cleaning operation.

[0045] Cleaning mechanism

[0046] The cleaning mechanism is installed on the frame 1 and is used for cleaning the vehicle. In addition to the horizontal brush 3, the brush holding mechanism 4 and the high-pressure water jet 12 mentioned above, the cleaning mechanism also includes components such as a water pipe 14 and a nozzle 15. The water pipe 14 is connected to the water source and the cleaning liquid supply system. The cleaning liquid and water are sprayed onto the surface of the vehicle through the nozzle 15, and the horizontal brush 3 and the brush holding mechanism 4 are used for brushing to achieve comprehensive cleaning of the vehicle.

[0047] Sensors and Control Panels

[0048] The sensor is electrically connected to the control panel 2 for monitoring the distance and height of the vehicle and transmitting the signal to the control panel 2. The control panel 2 adjusts the adjustment force of the first drive mechanism 7 and the second drive mechanism 8 according to the signal from the sensor, so that the horizontal brush 3 and the brush holding mechanism 4 can be accurately adjusted according to the actual size and position of the vehicle. At the same time, the control panel 2 also controls the switch of the cleaning mechanism according to the specific position of the vehicle to realize automatic control of the cleaning process.

[0049] When the vehicle is ready to enter the car wash machine, the driver follows the guidance of the guide mechanism 5 and drives the left wheel of the vehicle into the lane surrounded by the guide rod 51 and the anti-deflection rod 52, places the right wheel on the guide steel bar 53, and the vehicle slowly drives into the vehicle entrance of the frame 1 along the guide mechanism 5. At this time, the sensor installed on the frame 1 starts to work, monitors the distance and height of the vehicle in real time, and transmits the monitoring signal to the control panel 2.

[0050] When the vehicle enters the entrance of the frame 1, the high-pressure water jets 12 installed on the left and right sides of the second fixing frame 11 and on the top crossbeam at the entrance of the frame 1 start to work and perform high-pressure washing on the surface of the vehicle. The high-pressure water flow ejected by the high-pressure water jet 12 can quickly remove most of the dust and dirt on the surface of the vehicle, creating good conditions for subsequent cleaning work.

[0051] When the vehicle is being washed, the control panel 2 controls the extension and retraction of the first cylinder 73 of the first driving mechanism 7 according to the vehicle height signal transmitted by the sensor. The first cylinder 73 pushes the first swing arm 74 to rotate around the positioning rod 75, thereby adjusting the upper and lower positions of the horizontal brush 3 so that the horizontal brush 3 can fit the top and sides of the vehicle. At the same time, the first motor 71 drives the first mounting shaft 72 to rotate, driving the horizontal brush 3 to rotate, and brushing the top and sides of the vehicle.

[0052] The control panel 2 controls the extension and retraction of the second cylinder 81 of the second driving mechanism 8 according to the vehicle width signal transmitted by the sensor. The second cylinder 81 pushes the second swing rod 84 to rotate around the rotating rod 82, so that the left front brush 41, the right front brush 42, the left rear brush 43 and the right rear brush 44 of the brush mechanism 4 are opened and closed according to the width of the vehicle to fit the side and front and rear parts of the vehicle. The second motor drives the second mounting shaft 85 to rotate, driving the brush to rotate, and brushing the side and front and rear parts of the vehicle. While the brush is working, the water pipe 14 sprays water onto the surface of the vehicle through the nozzle 15, and cooperates with the brush to clean, thereby improving the cleaning effect.

[0053] When the vehicle is cleaned, it continues to move forward to the exit of the frame 1. At this time, the third motor 91 of the blower mechanism 9 drives the blower 92 to rotate at a high speed, generating a strong wind force to dry the surface of the vehicle body. The wind force of the blower 92 can quickly dry the moisture on the surface of the vehicle body, so that the vehicle remains basically dry when leaving the car washing machine.

[0054] After being cleaned and dried, the vehicle smoothly drives out of the car washing machine along the guide mechanism 5, completing the entire car washing process.

[0055] During the entire car washing process, the sensor continuously monitors information such as the position, distance and height of the vehicle, and transmits the signal to the control panel 2 in real time. The control panel 2 dynamically adjusts the actions of the first drive mechanism 7 and the second drive mechanism 8 according to these signals to ensure that the horizontal brush 3 and the brush holding mechanism 4 always maintain a suitable distance and pressure with the vehicle to achieve the best cleaning effect. At the same time, the control panel 2 also controls the switch of the cleaning mechanism (such as the high-pressure water jet 12, the water pipe 14 and the nozzle 15) according to the position of the vehicle to avoid unnecessary waste of water resources.

[0056] The guiding rod 51 and the anti-deflection rod 52 of the guiding mechanism 5 in the present device are made of high-strength steel and are firmly fixed to the ground by embedded bolts. The surfaces of the guiding rod 51 and the anti-deflection rod 52 are anti-skid treated to ensure that the vehicle tires have good friction during driving. The fixing plate 54 is also made of steel and is fixedly connected to the ground by expansion bolts. The guide steel bars 53 are welded to the fixing plate 54. The height and spacing of the guide steel bars are designed according to the tire sizes of common vehicles, which can effectively guide the driving direction of the vehicle.

[0057] The left front brush 41, the right front brush 42, the left rear brush 43 and the right rear brush 44 of the brush mechanism 4 are made of high-quality brush material with good flexibility and wear resistance. The length and density of the brushes are adjusted according to different cleaning requirements to ensure that they can fully contact the vehicle surface and achieve the best cleaning effect. The hollow structure of the second swing arm 84 is made of aluminum alloy material, which not only ensures the strength of the structure but also reduces the weight. The water pipe 14 is made of corrosion-resistant plastic pipe, and the nozzle 15 is a high-pressure atomizing nozzle, which can evenly spray the cleaning liquid and water onto the vehicle surface.

[0058] The first cylinder 73 of the first driving mechanism 7 and the second cylinder 81 of the second driving mechanism 8 both adopt high-quality pneumatic components with good sealing and reliability. The first motor 71, the second motor and the third motor 91 all adopt high-efficiency and energy-saving motors, which can meet the power requirements of the car washing machine. During the installation process, the connections between the components are made by bolts and pins to ensure that the connections are firm and reliable. At the same time, the moving parts are regularly lubricated and maintained to ensure their normal operation.

[0059] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
