Description

Technical Field

[0001] This utility model relates to the field of car wash equipment technology, and in particular to a trackless tunnel car wash machine. Background Technology

[0002] Existing tunnel-type car wash machines require chains or plate chains to drive tracks that pull vehicles from the machine's entrance to the exit. While this allows for programmed speed control and effective washing, the high cost of the vehicle-pulling track system, coupled with the need for concrete excavation and other civil engineering work, leads to long construction periods, high costs, and regulatory constraints related to safety and environmental policies, thus limiting user enthusiasm for deploying these machines. Furthermore, existing car wash machines typically occupy over 8 meters of space, making them unsuitable for small locations. Moreover, existing tunnel-type car wash machines generally suffer from complex structures, insufficient vehicle guidance precision, and poor adaptability of the cleaning mechanism. Traditional equipment, relying on fixed tracks or complex mechanical structures, struggles to adapt to varying vehicle sizes, and its cleaning efficiency and drying performance require improvement.

[0003] In conclusion, there is an urgent need in the market for a tunnel-type car wash machine that is compact, highly intelligent, adaptable to vehicle size, and occupies less than 8 meters in length, in order to reduce deployment costs and meet the growing car wash requirements of customers.

Detailed Implementation

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

[0032] like Figure 1-9 As shown, this utility model provides a trackless tunnel car wash machine, including a frame 1. The dimensions of the frame 1 are 8000*3900*3150mm (length*width*height). The frame 1 is the main structure of the entire car wash machine, with the vehicle inlet and outlet at its two ends. The frame 1 provides installation support for other components, ensuring that each component can operate stably. Warning signs 6 are installed at the inlet and outlet of the frame 1 to remind vehicle drivers to pay attention to safety and avoid accidents such as collisions.

[0033] Cleaning components

[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 drive mechanism 7 and can be adjusted up and down according to the height and position of the vehicle to achieve effective cleaning of different vehicle models.

[0035] Brush Mechanism: The brush mechanism 4 is installed on the frame 1 and is used to clean 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 four brushes are arranged in a parallelogram at their center positions, and all four brushes are driven by the second drive mechanism 8. This layout allows the brushes to better conform to the side curves of the vehicle and improve the cleaning effect.

[0036] High-pressure water jets: High-pressure water jets 12 are installed on the left and right sides of the second fixed frame 11 and on the top crossbeam at the entrance of the frame 1. The high-pressure water jets 12 can perform a preliminary high-pressure rinse on the vehicle surface when the vehicle enters the car wash machine, removing most of the dust and dirt on the vehicle surface and preparing it for subsequent cleaning work.

[0037] Drive adjustment mechanism

[0038] First driving mechanism: The first driving mechanism 7 is mounted on the second fixed frame 11 and is used to drive and adjust the position of the horizontal brush 3. The first driving mechanism 7 includes a first cylinder 73 and two first swing rods 74 mounted on the second fixed frame 11. The output end of the first cylinder 73 is hinged to a first swing rod 74. A first motor 71 is mounted on the first swing rod. A first mounting shaft 72 is mounted on the output end of the first motor 71. The horizontal brush 3 is mounted on the first mounting shaft 72. Positioning rods 75 are mounted 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 mounted on the two first swing rods 74. The two connecting rods 76 are connected via a crossbar 77. When the first cylinder 73 extends or retracts, it drives the first swing rods 74 to rotate around the positioning rod 75, thereby realizing the vertical 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 to perform cleaning operations.

[0039] Second drive mechanism: The second drive mechanism 8 is mounted on two first fixed frames 10 and is used to adjust the position of the brush holding mechanism 4. The second drive mechanism 8 includes two second cylinders 81 respectively mounted on both sides of the first fixed frame 10 and two rotating rods 82 rotatably connected to both sides of the first fixed frame 10. Triangular frames 83 are fixedly connected to the upper and lower sides of the outer surface of the rotating rods 82 respectively. A second swing rod 84 is fixedly connected to the end of the triangular frame 83 away from the rotating rod 82 respectively. A second mounting shaft 85 is rotatably connected to the upper surface of the end of the second swing rod 84 away from the rotating rod 82 respectively. A second motor is mounted on the second mounting shaft 85. The brush holding mechanism is mounted on the second mounting shaft 85. The output end of the second cylinder 81 is hinged to the second swing rod 84. When the second cylinder 81 extends or retracts, it pushes the second swing rod 84 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 to perform cleaning operations.

[0040] The optimized structure of the second swing arm: A guide rod 87 is installed on one end of the second swing arm 84 near the first fixed frame 10. An arc-shaped guide rail 86 adapted to the guide rod 87 is fixed on the first fixed frame 10. The guide rod 87 slides in the arc-shaped 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 mechanism 4. In addition, the second swing arm 84 is a hollow structure. A support rod 13 is installed at the center of the opposite side of the two second swing arms 84. A water pipe 14 is installed on the support rod 13. The transport part of the water pipe 14 is installed inside 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. A nozzle 15 for water discharge is installed on the water spraying part of the water pipe 14. This structural design makes the arrangement of the water pipe 14 more reasonable and avoids interference to the water pipe during movement. At the same time, the nozzle 15 can spray water onto the surface of the vehicle to clean it in conjunction with the brush.

[0041] Hair dryer

[0042] The blower mechanism 9 is installed at one end of the vehicle exit of the frame 1 to dry the water on the vehicle body. The blower mechanism 9 includes multiple third motors 91 installed on the upper crossbeam at the vehicle exit of the frame 1. The output end of the third motor 91 is equipped with a fan 92. When the vehicle is cleaned and passes through the exit, the third motor 91 drives the fan 92 to rotate at high speed, generating a strong air force to dry the water on the surface of the vehicle body.

[0043] Guiding agency

[0044] The guiding mechanism 5 is located directly below the frame 1 and fixed to the ground for the correct entry and exit of vehicles. The guiding 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-deviation rods 52. The guide rods 51 and anti-deviation rods 52 are arranged in a Y-shape. Both the guide rods 51 and anti-deviation rods 52 are fixed to the ground. On the other side directly below the frame 1, a fixing plate 54 is evenly installed. The fixing plate 54 is fixed to the ground and a guide steel bar 53 is installed on the fixing plate 54. The left and right wheels of the car are respectively placed in the lane formed by the guide rods 51 and anti-deviation rods 52 and on the guide steel bar 53. This can guide the vehicle to enter the car wash machine accurately, avoid the vehicle deviation, and ensure the smooth progress of the washing operation.

[0045] Cleaning facilities

[0046] The cleaning mechanism is installed on the frame 1 and is used to clean 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 water pipe 14 and nozzle 15. The water pipe 14 is connected to the water source and cleaning fluid supply system. The cleaning fluid and water are sprayed onto the vehicle surface through the nozzle 15. With the brushing of the horizontal brush 3 and the brush holding mechanism 4, the vehicle is thoroughly cleaned.

[0047] Sensors and Control Panel

[0048] The sensor is electrically connected to the control panel 2 to monitor the distance and height of the vehicle and transmit 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 the automated control of the cleaning process.

[0049] When a vehicle is about to enter the car wash machine, the driver follows the guidance of the guide mechanism 5 to drive the left wheel of the vehicle into the lane formed by the guide rod 51 and the anti-deviation rod 52, and place the right wheel on the guide steel bar 53. The vehicle slowly drives into the inlet 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 frame 1, the high-pressure water jets 12 installed on the left and right sides of the second fixed frame 11 and on the top crossbeam at the entrance of frame 1 start to work, and perform high-pressure washing on the surface of the vehicle. The high-pressure water jets 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 washing the vehicle, the control panel 2 controls the extension and retraction of the first cylinder 73 of the first drive mechanism 7 based on 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 up and down position 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, which drives the horizontal brush 3 to rotate and wash the top and sides of the vehicle.

[0052] Control panel 2 controls the extension and retraction of the second cylinder 81 of the second drive mechanism 8 based on the vehicle width signal transmitted by the sensor. The second cylinder 81 pushes the second swing arm 84 to rotate around the rotating rod 82, so that the left front brush 41, right front brush 42, left rear brush 43 and right rear brush 44 of the brush mechanism 4 open and close according to the width of the vehicle, fitting the sides and front and rear parts of the vehicle. The second motor drives the second mounting shaft 85 to rotate, driving the brushes to rotate and brush the sides and front and rear parts of the vehicle. While the brushes are working, the water pipe 14 sprays water onto the vehicle surface through the nozzle 15, which works in conjunction with the brushes to improve the cleaning effect.

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

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

[0055] Throughout the car wash process, sensors continuously monitor the vehicle's position, distance, and height, transmitting the signals 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 based on these signals, ensuring that the horizontal brush 3 and the brush holding mechanism 4 maintain a suitable distance and pressure from the vehicle to achieve the best cleaning effect. At the same time, the control panel 2 also controls the on / off switching of the cleaning mechanisms (such as the high-pressure water jet 12, water pipe 14, and nozzle 15) based on the vehicle's position to avoid unnecessary waste of water resources.

[0056] In this device, the guide rod 51 and anti-deviation rod 52 of the guide mechanism 5 are made of high-strength steel and are firmly fixed to the ground by pre-embedded bolts. The surfaces of the guide rod 51 and anti-deviation rod 52 are treated with anti-slip material to ensure that the vehicle tires have good friction during driving. The fixing plate 54 is also made of steel and is fixed to the ground by expansion bolts. The guide steel bar 53 is welded to the fixing plate 54, and its height and spacing are designed according to the tire size of common vehicles, which can effectively guide the driving direction of the vehicle.

[0057] The left front brush 41, right front brush 42, left rear brush 43, and right rear brush 44 of the brush mechanism 4 are made of high-quality brush material, which has good flexibility and wear resistance. The length and density of the brushes are adjusted according to different cleaning needs 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 ensures the strength of the structure and 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 drive mechanism 7 and the second cylinder 81 of the second drive mechanism 8 both use high-quality pneumatic components, which have good sealing and reliability. The first motor 71, the second motor and the third motor 91 all use high-efficiency and energy-saving motors, which can meet the power requirements of the car wash machine. During the installation process, the connection between each component is made by bolts and pins to ensure that the connection is firm and reliable. At the same time, each moving part is regularly lubricated and maintained to ensure its normal operation.

[0059] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
