Description

Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a rotary table type automatic car wash system. Background Technology

[0002] Cars are a common means of transportation for daily travel, and with the continuous increase in car ownership, car wash services have become widely promoted. Using automatic car wash equipment can achieve automatic car washing and reduce labor costs. Current automatic car wash machines typically use a tunnel-type structure. After a car enters the washing area, it moves along a guide rail in the tunnel. During this movement, the car is automatically washed through steps such as foam spraying, brush cleaning, water rinsing, and fan drying. This tunnel-type structure cannot freely set and dynamically modify the car's entry / exit points; the distance between the brushes / spray nozzles and the car body cannot be automatically set and changed in real time. With technological advancements, there is a need to improve the flexibility of application scenarios and reduce overall energy consumption.

[0003] Chinese patent publication CN105752045A discloses a rotary car wash robot, which is equipped with a turntable to carry cars for washing and uses a 3D laser scanner to create a 3D model of the car on-site. Then, based on the 3D model information, it cleans the car with brushes. However, the 3D laser scanner is expensive, and the operation and modeling time are too long, posing a practical dilemma. Furthermore, In the current cleaning process using brushes, the small coverage area of ​​the brushes results in low overall cleaning efficiency. Furthermore, the rotating platform requires ramps for vehicle entry and exit, limiting vehicle access and reducing usability. Therefore, designing a technology that improves both cleaning efficiency and usability is the technical problem this application aims to solve. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-5 As shown, the rotary table automatic car wash system of this embodiment includes: Turntable assembly 1, the turntable assembly 1 including vehicle platform 11 and rotation drive 12, the rotation drive 12 being configured to drive the vehicle platform 11 to rotate; The cleaning assembly 2 includes a movable frame 21, a first cleaning roller 22, a second cleaning roller 23, a rinsing nozzle 24, a foam nozzle 25, and a moving drive 26. The first cleaning roller 22 is arranged vertically and rotatably mounted on the movable frame 21, the second cleaning roller 23 is arranged laterally and rotatably mounted on the movable frame 21, the rinsing nozzle 24 and the foam nozzle 25 are mounted on the movable frame 21, and the moving drive 26 is configured to drive the movable frame 21 toward or away from the vehicle platform 11. Data acquisition component 3 is configured to acquire the outer contour information of the vehicle on the vehicle platform 11.

[0024] Specifically, the vehicle platform 11 in the turntable assembly 1 is used to carry the car that needs to be cleaned. After the car drives onto the vehicle platform 11, the vehicle platform 11 can be driven to rotate by rotating the drive component 12.

[0025] During the rotation of the vehicle platform 11, the vehicle platform 11 will drive the car to rotate together. During the rotation of the car, the data acquisition component 3 will collect the outer contour information of the rotating car, thereby obtaining the outer contour information of the car on the vehicle platform 11.

[0026] During the cleaning process, the vehicle platform 11 will drive the car to rotate relative to the cleaning assembly 2. The cleaning assembly 2 will adjust the distance between the first cleaning roller 22 and the second cleaning roller 23 on the moving frame 21 and the outer surface of the car according to the outer contour information of the car. This ensures that the two cleaning rollers are kept within a reasonable distance from the outer surface of the car, which ensures that the cleaning rollers can effectively clean the outer surface of the car and also ensures that the cleaning rollers will not cause collision damage to the car.

[0027] In addition, during the cleaning process, the first cleaning roller 22 can effectively clean the sides of the car, and the second cleaning roller 23 will effectively clean the top of the car.

[0028] For ease of control, the rotary table automatic car wash system also includes a controller (not shown), which is electrically connected to the data acquisition component 3, the rotation drive component 12 and the movement drive component 26.

[0029] Specifically, the controller can use conventional industrial control devices such as a PLC. The controller can control the operation of the turntable assembly 1 and the cleaning assembly 2. Specifically, after the car drives onto the vehicle platform 11, the controller will control the rotation drive 12 to start, so as to drive the vehicle platform 11 to rotate. At the same time, the controller controls the data acquisition assembly 3 to collect the outer contour information of the rotating car. After collecting the outer contour information, the controller will control the operation of the cleaning assembly 2. Meanwhile, the vehicle platform 11 continues to rotate. The controller controls the moving frame 21 in the cleaning assembly 2 to move closer to or away from the car based on the collected outer contour information of the car, so as to adjust the distance between the first cleaning roller 22, the second cleaning roller 23 and the car surface.

[0030] Preferably, the cleaning components 2 can be provided on both sides of the vehicle platform 11.

[0031] Specifically, during use, the two cleaning components 2 will simultaneously clean both sides of the car to improve cleaning efficiency. Additionally, the two first cleaning rollers 22 in the two cleaning components 2 can be at the same height; in this case, the height of the first cleaning rollers 22 must be sufficient to cover the sides of the car.

[0032] Alternatively, to shorten the length of a single first cleaning roller 22, the height of the first cleaning roller 22 on the left side of the figure can be higher than that of the first cleaning roller 22 on the right side of the figure. In this way, the two first cleaning rollers 22 at different heights have an overlapping area in the height direction, so that the side of the car can be effectively cleaned with a shorter first cleaning roller 22.

[0033] In addition, the physical entity representing the moving drive component 26 can be a conventional linear drive mechanism such as a linear motor, and there are no restrictions here.

[0034] For the vehicle platform 11, all areas around its outer perimeter, except for those where the cleaning components 2 are located, can accommodate vehicle entry and exit. After a vehicle drives onto the vehicle platform 11, the rotation drive 12 uses a servo motor to drive the vehicle platform 11 to rotate, enabling continuous adjustable speed rotation and precise positioning at any position within a 360-degree circle. This allows the vehicle to exit at a customized location after cleaning. The rotation speed and angle of the vehicle platform 11 are matched with the moving speed and position of the first cleaning roller 22 and the second cleaning roller 23 on the moving frame 21 to ensure a relatively stable distance between the vehicle surface and the cleaning rollers and nozzles, thereby improving the cleaning effect.

[0035] The rotary table automatic car wash system can freely set the vehicle loading and unloading points according to different car wash scenarios. During the car wash process, facing different vehicle body contours, as the vehicle body rotates with the rotary table, it ensures that the distance between the nozzles and brush rollers and the vehicle body surface can be freely set and kept constant in real time.

[0036] The data acquisition component 3 collects data on the outer contour of the car on the vehicle platform 11 to obtain the car's position and relevant external dimensional parameters on the vehicle platform 11. During the cleaning process, the moving frame 21 in the cleaning component 2 moves towards the vehicle platform 11 so that the first cleaning roller 22 and the second cleaning roller 23 contact the car surface for cleaning. Simultaneously, during the cleaning process, the rinsing nozzle 24 and foam nozzle 25 are arranged on the moving frame 21, enabling them to clean and spray foam on the car as the vehicle platform 11 rotates. Furthermore, the first cleaning roller 22 can... The sides of the car are cleaned, and correspondingly, the second cleaning roller 23 can clean the top of the car, so that the car is thoroughly and efficiently cleaned by the first cleaning roller 22 and the second cleaning roller 23 as it rotates with the vehicle platform 11. More importantly, since the car has rearview mirrors on both sides and a protruding antenna mount on the top, in order to ensure cleaning safety, the moving frame 21 will move in advance according to the outer contour information collected by the data acquisition component 3 during the rotation of the vehicle platform 11, so that the first cleaning roller 22, the second cleaning roller 23 and the car are kept at a safe distance, thereby improving the safety and reliability of use.

[0037] In one embodiment, the rinsing nozzle 24 and the foam nozzle 25 can be designed separately, with each nozzle performing the rinsing and foam spraying operations independently. Alternatively, the rinsing nozzle 24 and the foam nozzle 25 can be integrated into a single nozzle, with the nozzle switching between spraying clean water or foam via a reversing valve. Additionally, to remove water from the car's surface, an air-blowing nozzle (not shown) can be mounted on the mobile frame. This air-blowing nozzle is supplied with air by an on-site air compressor and uses high-pressure air to dry the vehicle body.

[0038] In one embodiment, the data acquisition component 3 includes a plurality of laser rangefinders 31, some of which are arranged vertically side by side and / or some of which are arranged horizontally side by side.

[0039] Specifically, by using multiple laser rangefinders 31 to measure the outer contour information of the car, the outer contour size information at different height positions of the car can be accurately obtained, so as to facilitate the control of the operation of the cleaning component 2.

[0040] The laser rangefinder 31 can quickly and efficiently detect the distance to the outer surface of the car, and then use the data collected by multiple laser rangefinders 31 to build a data model to obtain the car's outer contour information. Compared with conventional technology that uses a 3D laser scanner to scan the car body, the laser rangefinder 31 scans the car body's outer contour faster, efficiently collects vehicle contour data, and is more conducive to quickly obtaining modeling information to meet the needs of subsequent car washing.

[0041] The laser rangefinder 31 is mounted on the movable frame 21. Specifically, the movable frame 21 is used to meet the installation requirements of the laser rangefinder 31. During the process of acquiring vehicle outline information through the laser rangefinder 31, the movable frame 21 remains stationary in a set position to collect data.

[0042] Alternatively, the data acquisition component 3 may also include a support frame (not shown), which is arranged on one side of the vehicle platform 11, and the laser rangefinder 31 is mounted on the support frame. Specifically, the data acquisition component 3 may also include a separate support frame, which is arranged on one side of the vehicle platform 11 to meet the requirements for installing the laser rangefinder 31.

[0043] Preferably, to improve reliability, the data acquisition component 3 further includes an air nozzle 32 configured to dry water droplets on the surface of the laser rangefinder 31.

[0044] Specifically, during the car washing process, the water sprayed from the wash nozzle 24 can easily splash onto the surface of the laser rangefinder 31, affecting its detection accuracy. This is especially true for the process of collecting outer contour information when the next car enters the vehicle platform 11. To address this, an air nozzle 32 is configured to blow air onto the laser rangefinder 31, effectively cleaning the water droplets from its surface and ensuring the reliable operation of the laser rangefinder 31.

[0045] In one embodiment, the first cleaning roller 22 includes a first cleaning frame 221, a first brush roller 222, a first rotating shaft 223, a first drive motor 224, and a transverse drive member 225. The first rotating shaft 223 is arranged vertically and rotatably mounted on the first cleaning frame 221. The first drive motor 224 is configured to drive the first rotating shaft 223 to rotate. The first brush roller 222 is mounted on the first rotating shaft 223. The first cleaning rack 221 is slidably disposed on the movable rack 21, and the lateral drive member 225 is configured to drive the first cleaning rack 221 to slide laterally.

[0046] Specifically, the first cleaning roller 22 is supported and mounted on the first brush roller 222 via the first rotating shaft 223. The first drive motor 224 can drive the first rotating shaft 223 to rotate, so as to meet the requirements of the first brush roller 222 for rotation and cleaning. In order to accurately adjust the distance between the first brush roller 222 and the side of the car, the first cleaning frame 221 is driven to move laterally on the moving frame 21 by the lateral drive member 225, so as to accurately adjust the position of the first brush roller 222.

[0047] In one embodiment, the first cleaning frame 221 is further provided with a rotatable swing frame 229. The first brush roller 222, the first rotating shaft 223, and the first drive motor 224 are disposed on the swing frame 229. The first cleaning frame 221 is also provided with a swing drive component 228, which drives the swing frame 229 to rotate, thereby further precisely controlling the distance between the first rotating shaft 223 and the car surface, so that the first brush roller 222 can effectively clean the car surface. The swing drive component 228 can be manifested as a servo motor.

[0048] In some embodiments, to improve the cleaning effect and ensure the safety of cleaning, a first limit switch 226 is also provided on the first rotating shaft 223. A first detection rod 227 is provided on the operator of the first limit switch 226. A first anti-scratch sleeve is fitted over the first detection rod 227. The first detection rod 227 is arranged perpendicular to the first rotating shaft 223 and extends into the bristles of the first brush roller 222. Specifically, during the car wash process, to improve safety, the distance between the first shaft 223 of the first brush roller 222 and the side of the car needs to be strictly controlled to prevent the first brush roller 222 from excessively pressing against the side of the car and damaging the paint. To this end, a first limit switch 226 is integrated and installed on the first shaft 223. The actuator of the first limit switch 226 is equipped with a first detection rod 227, and a flexible first anti-scratch sleeve is fitted onto the first detection rod 227. During normal use, the first detection rod 227 is located within the bristles of the first brush roller 222. When the bristles contact the side of the car, they bend. The pressure exerted by the bent bristles on the first detection rod 227 is insufficient to trigger the actuator of the first limit switch 226, thus ensuring that the first brush roller 222 can properly clean the side of the car. When the first brush roller 222 gets too close to the car's surface, it generates greater friction on the paint. At this point, the first anti-scratch sleeve contacts the car's surface, triggering the actuator via the first detection rod 227. This causes the first limit switch 226 to activate and send a signal to the controller. If the first brush roller 222 only presses against the car for a short time (500ms~3s), the controller, upon receiving the signal, will control the swing drive 228 to rotate the swing frame, causing the first brush roller 222 to move away from the car until the first limit switch 226 resets. However, if the first brush roller 222 presses against the car for a long time (greater than 3s), after a set time (e.g., 3s), the first drive motor 224 can be stopped to reduce scratches on the car's paint, thus improving safety and reliability. Furthermore, after a malfunction repair, the washing assembly 2 will resume the car wash program from the angle of the shutdown point to ensure the vehicle can complete the final car wash operation normally and efficiently.

[0049] In some embodiments, to facilitate the installation of rinsing nozzles 24 and foam nozzles 25 for cleaning and spraying foam on the sides of the vehicle, a plurality of rinsing nozzles 24 and a plurality of foam nozzles 25 are provided on the first cleaning rack 221, with the plurality of rinsing nozzles 24 arranged sequentially from top to bottom and the plurality of foam nozzles 25 arranged sequentially from top to bottom.

[0050] Specifically, a rinsing nozzle 24 and a foam nozzle 25 can be installed on the side of the first washing rack 221, allowing the rinsing nozzle 24 and foam nozzle 25 to be closer to the side of the vehicle. Similarly, a laser rangefinder sensor 31 for detecting the side of the vehicle can also be installed on the side of the first washing rack 221 for ease of installation.

[0051] In another embodiment, in order to meet the needs of spraying and washing the top of the car, the movable frame 21 is also provided with a suspension frame 28, which is also provided with a rinsing nozzle 24 and a foam nozzle 25. The rinsing nozzle 24 and the foam nozzle 25 on the suspension frame 28 can spray downwards from above the car.

[0052] In some embodiments, the first washing rack 221 is provided with a limit detector 27, which is configured to trigger a temporary shutdown of the turntable automatic car wash system after contacting a car on the vehicle platform 11.

[0053] Specifically, the limit detector 27 installed on the first cleaning frame 221 can further control the distance between the first brush roller 222 and the side of the car through mechanical limiting. The limit detector 27 is located on one side of the first cleaning frame 221. When the moving frame 21 or the first cleaning frame 221 moves excessively towards the car due to a malfunction, the limit detector 27 will first contact the car. After contacting the car, the limit detector 27 will send a signal to the controller. If the first brush roller 222 is only pressing the car for a short time (500ms~3s), after receiving the signal, the controller will control the swing drive 228 to drive the swing frame to rotate so that the first brush roller 222 moves away from the car until the limit detector 27 resets. However, if the first brush roller 222 is pressing the car for a long time (greater than 3s), after exceeding the set time (e.g., 3s), the first drive motor 224 can be controlled to stop rotating, and the lateral drive 225 can be controlled to move the first cleaning frame 221 away from the car, thereby reducing scratches on the car's paint and improving safety and reliability. Furthermore, after a malfunction is repaired, the washing component 2 will continue the car wash program from the angle position of the shutdown point to ensure that the vehicle can complete the car wash operation normally and efficiently.

[0054] In one embodiment, the second cleaning roller 23 includes a second cleaning frame 231, a second brush roller 232, a second rotating shaft 233, a second drive motor 234, and a vertical drive member 235. The second rotating shaft 233 is arranged laterally and rotatably mounted on the second cleaning frame 231. The second drive motor 234 is configured to drive the second rotating shaft 233 to rotate. The second brush roller 232 is mounted on the second rotating shaft 233. The second cleaning rack 231 is vertically slidably mounted on the movable rack 21, and the vertical drive member 235 is configured to drive the second cleaning rack 231 to slide vertically.

[0055] Specifically, the second cleaning roller 23 supports and mounts the second brush roller 232 via the second rotating shaft 233. The second drive motor 234 drives the second rotating shaft 233 to rotate, thus meeting the requirements for the second brush roller 232 to rotate and clean. To precisely adjust the distance between the second brush roller 232 and the car roof, the second cleaning frame 231 is driven vertically on the movable frame 21 by a vertical drive component 235, thereby accurately adjusting the position of the second brush roller 232.

[0056] In some embodiments, in order to improve the cleaning effect and ensure the safety of cleaning, a second limit switch 236 is also provided on the second rotating shaft 233. A second detection rod 237 is provided on the operator of the second limit switch 236. A second anti-scratch sleeve is fitted on the outside of the second detection rod 237. The second detection rod 237 is arranged perpendicular to the second rotating shaft 233 and extends into the bristles of the second brush roller 232.

[0057] Specifically, during the car wash process, to improve safety, the distance between the second shaft 233 of the second brush roller 232 and the top of the car needs to be strictly controlled to prevent the second brush roller 232 from excessively pressing against the top of the car and damaging the paint. To this end, a second limit switch 236 is integrated and installed on the second shaft 233. The actuator of the second limit switch 236 is equipped with a second detection rod 237, and a flexible second anti-scratch sleeve is fitted onto the second detection rod 237. During normal use, the second detection rod 237 is located within the bristles of the second brush roller 232. When the bristles contact the top of the car, they bend. The pressure exerted by the bent bristles on the second detection rod 237 is insufficient to trigger the actuator of the second limit switch 236, thus ensuring that the second brush roller 232 can properly clean the top of the car. When the second brush roller 232 gets too close to the car's surface, it generates greater friction on the paint. At this point, the second anti-scratch sleeve contacts the car's surface, triggering the actuator via the second detection rod 237. This causes the second limit switch 236 to activate and send a signal to the controller. If the second brush roller 232 only presses against the car for a short time (500ms~3s), the controller, upon receiving the signal, will control the vertical drive component 235 to move the second cleaning frame 231, causing the second brush roller 232 to move away from the car until the second limit switch 236 resets. However, if the second brush roller 232 presses against the car for a longer period (greater than 3s), after a set time (e.g., 3s), the second drive motor 234 can be stopped, and the vertical drive component 235 can be controlled to move the second cleaning frame 231 away from the car, thereby reducing scratches on the car's paint and improving safety and reliability. Furthermore, after a malfunction is repaired, the washing component 2 will continue the car wash program from the angle position of the shutdown point to ensure that the vehicle can complete the car wash operation normally and efficiently.

[0058] The horizontal drive component 225 and the vertical drive component 235 can have various structural forms. For example, they can be implemented using a linear motor, or by using a motor in conjunction with a ball screw or other linear motion drive method. No restrictions or further details are provided here.

[0059] In one embodiment, in order to ensure that the vehicle platform 11 can smoothly drive the car to rotate, the bottom of the vehicle platform 11 is provided with a plurality of omnidirectional support wheels 13.

[0060] Specifically, the multiple universal support wheels 13 at the bottom of the vehicle platform 11 can provide good support for the vehicle platform 11, so that after the car drives onto the vehicle platform 11, the vehicle platform 11 can rotate smoothly under the driving action of the rotation drive component 12, relying on the multiple universal support wheels 13 at the bottom.

[0061] In one embodiment, the rotation drive 12 is a rotation drive motor, which is arranged below the vehicle platform 11.

[0062] Specifically, the rotation drive component 12 uses a rotation drive motor to drive the vehicle platform 11 to rotate. The rotation drive motor is located below the vehicle platform 11 to make full use of the space at the bottom for its installation. A support shaft (not shown) is provided at the bottom of the vehicle platform 11 to support its rotation. The rotation drive motor can be connected to the support shaft via a reducer, thereby driving the vehicle platform 11 to rotate.
