[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] like Figures 1 to 9As shown, this application provides a car wash robot, including: a robot body 100, comprising a support frame 10, a moving component 20, a control box 30, a solar panel 40, an AI camera 60, an infrared sensor 70, and a laser sensor 80. The support frame 10 has a rotating groove 11 on its outer side that is adapted to the moving component 20. The control box 30 is located at the upper end of the support frame 10, and the solar panel 40 is mounted on top of the control box 30. The AI ​​camera 60 and the infrared sensor 70 are both located on the outer side of the support frame 10. The moving component 20 includes a mounting bracket 21 installed inside the rotating groove 11, and a first drive motor 22 is mounted in the middle of the mounting bracket 21. A large arm 23 is provided on one side of the mounting bracket 21. A second drive motor 24 is provided at the connection between the two. A small arm 25 is provided on one side of the large arm 23, and a third drive motor 26 is provided at the connection between the two. A pneumatic suction cup 27 is installed at the bottom of the small arm 25. A charging interface 31 is provided on the outside of the control box 30. A PLC controller 32, a battery 33, and an electric vacuum pump 34 are provided inside the control box 30. A cleaning structure 50 is provided at the bottom of the support frame 10. It includes an inner shroud 51 located inside the support frame 10. A cleaning motor 52 is provided inside the inner shroud 51. The output end of the cleaning motor 52 is connected to a cleaning roller 53. A water pump 59 is provided inside the support frame 10. A nano-atomizing nozzle 510 and a water-blocking pad 58 are provided at the bottom of the support frame 10.

[0037] After adopting the above technical solution, since the moving component 20 is located on the outside of the support frame 10 and the cleaning structure 50 is set at the bottom of the support frame 10, during the car cleaning process, the external mobile phone app is connected to the PLC controller 32 to control the electric vacuum pump 34 to provide compressed air to the pneumatic suction cups 27. Multiple sets of pneumatic suction cups 27 can be attached to the car window. Then, the water pump 59 is controlled to spray the cleaning liquid inside the liquid storage tank 13 along the car body through the nano-atomizing nozzle 510. At the same time, after supporting the support frame 10, the output end of the cleaning motor 52 is controlled to drive the cleaning roller 53 to rotate and clean along the car body. After rotation, the corresponding pneumatic suction cup 27 can be controlled to stop suction, and the corresponding first drive motor 22 and second drive motor 23 can be controlled. The drive motor 24 and the third drive motor 26 rotate, which can drive the forearm 25 to rotate along the upper arm 23, the upper arm 23 to rotate along the mounting frame 21, and the mounting frame 21 to rotate along the inside of the rotating groove 11, thereby performing 180-degree and multi-angle rotations. This can adsorb and move the support frame 10, thereby supporting the crawling of the support frame 10. During the crawling process, cleaning agent is continuously sprayed through the nano-atomizing nozzle 510, the cleaning roller 53 continuously rotates and cleans, and the water barrier 58 isolates the water during the cleaning process to prevent it from splashing onto the car body after cleaning. At the same time, the air pump 54 is started, and external air is delivered into the interior of the connecting block 55 through the air pipe 56, and then blown out at high speed through the high-pressure blower head 57, thereby drying the car body and completing the cleaning.

[0038] It should be noted that, according to the appendix Figure 9 It is known that the PLC controller 32 has a control center in the middle, which is connected to the mobile APP module. The mobile APP can control the AI ​​camera 60, infrared sensor 70 and laser sensor 80. The infrared sensor 70 is used to detect the distance between the support frame 10 and the vehicle body, so that the cleaning roller 53 can fit the vehicle body. The AI ​​camera 60 can record the movement trajectory of the support frame 10, which plays a role in AI cleaning recognition. The laser sensor 80 can locate the initial position. After cleaning, it returns to the original position with the help of the AI ​​camera 60, thereby resetting the support frame 10. At the same time, when replacing corresponding parts, the AI ​​data management module records the process.

[0039] In an optional implementation, the laser sensor 80 is located at the bottom of the support frame 10 and is electrically connected to the PLC controller 32. It can be used to identify the initial position of the support frame 10 and to reposition the support frame 10 after cleaning or moving.

[0040] In one optional embodiment, the number of infrared sensors 70 is four sets arranged in an array. The infrared sensors 70 are electrically connected to the PLC controller 32 to detect the distance at the four corners of the support frame 10, so as to prevent the support frame 10 from hitting the car body. At the same time, the distance between the car body and the support frame 10 is detected to ensure that the cleaning roller 53 and the water-blocking pad 58 can always be in contact with the car body, thereby improving the cleaning efficiency.

[0041] In an optional implementation, the AI ​​camera 60 is electrically connected to the PLC controller 32, and can be used to record the movement of the support frame 10, while recording the movement trajectory and feeding it back to the PLC controller 32, so as to facilitate the subsequent installation of the recorded trajectory for movement.

[0042] In an optional embodiment, the electric vacuum pump 34 is connected to the pneumatic suction cup 27 via a conduit, the number of mounting brackets 21 is equal to the number of rotating slots 11, and the first drive motor 22, the second drive motor 24 and the third drive motor 26 are all electrically connected to the PLC controller 32.

[0043] It should be noted that during the movement of the moving component 20, compressed air is supplied to the pneumatic suction cup 27 by the electric vacuum pump 34, so that the pneumatic suction cup 27 can adhere to the vehicle body. The first drive motor 22 can drive the mounting frame 21 to rotate along the outside of the support frame 10, the second drive motor 24 can drive the large arm 23 to rotate along the outside of the mounting frame 21, and the third drive motor 26 can drive the small arm 25 to rotate along the outside of the large arm 23, ensuring that multiple moving components 20 can rotate at multiple angles. Through a spider-like crawling method, the robot body 100 can move flexibly on the surface of the vehicle body. The robot body 100 can adjust its posture as needed to easily cope with various complex vehicle body curves and corners, and can even cross the vehicle body from the roof to achieve all-round coverage.

[0044] In an optional embodiment, the support frame 10 has an injection port 12 on its outer side and a liquid storage tank 13 connected between the injection ports 12 inside the support frame 10, which facilitates the storage and injection of cleaning fluid and provides a basis for subsequent cleaning.

[0045] In an optional embodiment, the solar panel 40 is connected to the control box 30 by bolts, the solar panel 40 is electrically connected to the PLC controller 32, and an inverter module is installed on the outside of the solar panel 40, which can store the electrical energy generated by the solar panel 40 into the battery 33 through inverter. The battery 33 provides power for daily use, and when the power is insufficient, it can be charged through the charging interface 31.

[0046] In an optional embodiment, an air pump 54 is installed at the upper end of the support frame 10, and the air pump 54 is electrically connected to the PLC controller 32. A connecting block 55 is installed at the bottom of the support frame 10, and an air pipe 56 is connected to the air outlet of the air pump 54. Several sets of high-pressure blowers 57 are installed at the bottom of the connecting block 55, so that water stains can be dried after the cleaning roller 53 cleans the vehicle. At the same time, the vehicle body can be moved back and forth repeatedly and recorded by the AI ​​camera 60 until the cleaning is completed.

[0047] In an optional embodiment, the water-retaining pad 58 is an elastic and malleable structure, and the water-retaining pad 58 is connected to the support frame 10 by a snap fastener to prevent the cleaning roller 53 from throwing dirt onto the car body after cleaning during the rotation process.

[0048] In an optional embodiment, the water pump 59 is electrically connected to the PLC controller 32, and the input end of the water pump 59 is connected to the liquid storage tank 13 through a water pipe. The output end of the water pump 59 is connected to the nano-atomizing nozzle 510 through a high-pressure water pipe. The water inside the liquid storage tank 13 can be pumped out for cleaning, and the vehicle body can be sprayed through multiple sets of nano-atomizing nozzles 510 to wash away stains and soften stubborn stains.
