[0002] For people living in cities, due to urban expansion and work needs, cars have become an indispensable means of transportation. After a period of use, dust, mud, oil stains, and other factors can cause a layer of grime to accumulate on the vehicle's surface, requiring regular cleaning to maintain cleanliness and reduce wind resistance during driving.

[0003] With the increasing number of car owners, automatic car wash machines, as a new type of car washing equipment, are becoming increasingly popular. Automatic car wash machines offer advantages such as fast washing speed and no damage to the car's surface, saving labor costs for car wash shops. However, existing car wash machines require manual driving of the car onto the conveyor belt before washing. When the driver gets out of the car, parts of the machine's structure can obstruct the view, making it inconvenient and potentially dangerous, thus requiring a dedicated person to supervise. Furthermore, parking the car in the designated washing position within the machine before washing is not easy, as it's prone to veering off course. Drivers also cannot see the exact position of their wheels and cannot park the car in a specific spot. Additionally, driving into the machine can damage the conveyor belt, making drivers feel risky and resulting in a poor experience.

[0004] Therefore, how to provide a universal inlet conveyor mechanism for tunnel-type unmanned car wash machines, which, through the cooperation of multiple sets of limiting structures and guiding devices, facilitates the driver's observation of the position, improves the parking accuracy in front of the car wash machine, and can automatically adjust when the accuracy is poor, so as to ensure that the vehicle can accurately and automatically run into the tunnel-type unmanned car wash machine and complete the car wash operation, has become a technical problem that urgently needs to be solved by those skilled in the art.

[0037] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0038] like Figure 1-6As shown, a universal inlet conveyor mechanism for a tunnel-type unmanned car wash includes a self-service section auxiliary conveyor 6 and an integrated guide 7. Both the integrated guide 7 and the self-service section auxiliary conveyor 6 are installed on the ground foundation in front of the main body of the car wash and are vertically distributed. It also includes a transition guide plate 9. A single-rail single-chain conveyor 13 is installed on one side of the ground foundation inside the main body of the car wash. The transition guide plate 9 is positioned between the integrated guide 7 and the single-rail single-chain conveyor 13. The self-service section auxiliary conveyor 6 is positioned on the other side and parallel to the transition guide plate 9. An entrance monitoring rod 11 is located above the self-service section auxiliary conveyor 6 and the transition guide plate 9. A sound and light controller 3 is installed in front of the left vertical bar of the entrance monitoring rod 11, and a barrier gate assembly 4 is installed behind the left vertical bar of the entrance monitoring rod 11. A camera 12 and a lighting lamp are installed on the top horizontal bar of the entrance monitoring rod 11. Multiple vehicle positioning devices are installed on the ground foundation in front of the main body of the car wash. The camera 12 is designed to capture the vehicle's position. The captured image is then transmitted to the controller for recognition and calculation. Adjustment instructions are then sent to the corresponding equipment to guide and adjust the vehicle's position. Specifically, the audio-visual controller 3 can issue commands to the driver to align one side of the vehicle's wheels with the inlet of the integrated guide 7 and the single-rail single-chain conveyor 13. The lighting design provides a bright environment for nighttime car washing, ensuring operational safety. The specific control program is implemented using existing programming technology and will not be elaborated upon here.

[0039] Specifically, the vehicle positioning device includes a set of vehicle arrival photoelectric beams 1 and a set of vehicle overshoot photoelectric beams 2.

The height of the transmitter and receiver corresponds to the height of the car's front end, ensuring that the front end of the car blocks the photoelectric beams after it has entered position. The vehicle arrival and overshoot photoelectric beams can detect the vehicle's position promptly and accurately. The monitoring signals from the vehicle arrival and overshoot photoelectric beams are transmitted to the main control box of the car wash machine, which then issues corresponding instructions to the audio-visual controller. The display screen and loudspeaker provide appropriate prompts, effectively reducing or even eliminating the need for personnel to give instructions.

[0040] Specifically, the integrated wheel guide 7 mainly includes an underground part and an above-ground figure-eight shaped guide rod. Both ends of the figure-eight shaped guide rod are connected to rotating wheels, facilitating the entry and straightening of the vehicle's left front wheel. The outlet end of the figure-eight shaped guide rod connects to the transition guide plate 9. The transition guide plate 9 includes a fixed foot plate connected to the ground foundation and a protective strip on top. The protective strip is made of flexible materials such as rubber and is snapped onto the top surface of the fixed foot plate, providing protection for the wheel. Meanwhile, the integrated wheel guide 7 is an existing structure; after purchase, it can be installed according to the instructions. The structure of the underground part can be referenced from the national patent, publication number CN108502498A, entitled "Structure of an Integrated Wheel Guide System for a Tunnel-Type Car Wash Machine," and will not be elaborated upon here.

[0041] Specifically, the vehicle positioning device also includes a front wheel guide convex mirror 5, which is mounted on the ground foundation by a support column and located on the left side of the transition guide plate 9, making it easier for the driver to park the vehicle in a reasonable waiting area.

[0042] like Figure 1 , 4 As shown, the front of the integrated guide 7 is a parking space to be washed, and a row of vehicle body limiting poles 8 is placed on the left side of the parking space to be washed. The multiple vehicle body limiting poles 8 are placed in a straight line.

[0043] Specifically, the vehicle body limiting pole 8 includes a fixed chassis 801, a hollow connecting sleeve 802, a central component 803, and protective sleeves 804. The central component 803 is positioned and connected to the fixed chassis 801 via the hollow connecting sleeve 802. Multiple protective sleeves 804 are fitted onto the central component 803 to protect the vehicle body. When the vehicle deviates from its designated position, the flexible contact between the two prevents scratches. This vehicle body limiting pole 8 is a detachable structure. When in use, the fixed chassis 801, hollow connecting sleeve 802, and central component 803 are assembled together to form a vertical pole. The overall structure is compact, lightweight, and easy to adjust. When not in use, it can be disassembled for easy storage and occupies little space.

[0044] During manufacturing, the fixed base 801 is made of metal material, and the surface of the fixed base 801 is provided with a hot-dip galvanized layer to ensure stability, improve corrosion resistance, and extend its service life; the central component 803 is made of fiberglass hollow tube, and the surface color of the fiberglass hollow tube is yellow; the hollow connecting sleeve 802 is made of polyurethane or rubber, and the protective sleeve 804 is made of flexible material, including black foam, rubber, or polyurethane.

[0045] Specifically, an auxiliary guide 10 is provided in front of the integrated guide 7. Two sets of auxiliary guides 10 are symmetrically arranged, corresponding to the left and right wheels of the vehicle. They are formed by multiple longitudinally arranged support rods. When the front wheel reaches this position, they assist in automatically guiding the wheel forward. A ground induction coil is laid in front of the auxiliary guide 10. This ground induction coil works in conjunction with the vehicle overtaking photoelectric sensor 2. When the vehicle overtaking photoelectric sensor 2 is not blocked and the ground induction coil outputs a signal, the payment conditions are met, and the driver of the vehicle to be washed can proceed with the payment operation according to the prompts.

[0046] Specifically, the barrier gate assembly 4 includes a barrier gate host 401 and a barrier gate arm 402. One end of the barrier gate arm 402 is rotatably connected to the outer top of the barrier gate host 401. A warning curtain 403 is connected to the barrier gate arm 402. The warning text on the warning curtain 403 is: Close the car window, retract the antenna, put it in neutral, do not step on the brake, and do not move the steering wheel.

[0047] Specifically, the self-service section auxiliary conveyor 6 includes a horizontal motor 601, a horizontal reducer 602 and a conveyor body. The horizontal motor 601 and the horizontal reducer 602 are arranged side by side and connected together. The horizontal motor 601 and the horizontal reducer 602 are located on one side of the conveyor body and are covered with a protective cover.

[0048] The conveyor body includes a mounting frame 603, an inlet shaft 604, an outlet shaft 605, and a set of angle steel 606 in the middle. An inlet extension plate 607 connects the inlet shaft 604 and the inlet plate of the mounting frame 603, and an outlet extension plate 608 connects the outlet shaft 605 and the outlet plate of the mounting frame 603. The inlet shaft 604 and the outlet shaft 605 are rotatably connected to the two side plates of the mounting frame 603 via bearings. The inlet shaft 604 and the outlet shaft 605 are connected together by a large sprocket and chain mechanism. The input end of the outlet shaft 605 passes through the side plate and is connected to the output shaft of the horizontal reducer 602 via a set of sprocket and chain assemblies. The large sprocket and chain mechanism includes two sets of large sprockets and two conveyor chains fitted together. The two sets of large sprockets are positioned on both sides of the inlet shaft 604 and the outlet shaft 605, and a conveyor roller is installed in the middle of the two conveyor chains. Specifically, the 606 angle steel is located below the top conveyor roller and the two are vertically distributed, mainly serving the function of support and positioning to ensure that the conveyor roller has sufficient support force.

[0049] When in use, the horizontal motor 601 starts, and after being reduced in speed by the horizontal reducer 602, the power is transmitted to the outlet shaft 605 through the sprocket and chain assembly and drives it to rotate. Then, through the large sprocket and chain mechanism, the conveyor chain and the connected conveyor roller rotate synchronously to realize the vehicle conveying operation and smoothly send the vehicles in the waiting area into the single-rail single-chain conveyor 13 inside the main body of the car wash machine.

[0050] A method for using a universal inlet conveyor mechanism for a tunnel-type unmanned car wash includes the universal inlet conveyor mechanism and the car wash body as described above. The universal inlet conveyor mechanism is installed in front of the car wash body, and the two cooperate to form an unmanned car wash system. The system also includes a main control box. The self-service section auxiliary conveyor 6, the sound and light controller 3, the barrier gate assembly 4, and the camera 12 are all electrically connected to the main control box. The main control box is used to receive all monitoring signals and issue corresponding instructions.

[0051] The main steps involved in its use are as follows:

[0052] Step 1, the vehicle enters:

[0053] First, the vehicle enters the washing area under the guidance of the ground guide lines and the vehicle body limit pillars;

[0054] Then, when the car wash machine meets the standby conditions, the display screen 301 of the sound and light controller 3 displays "forward" and the loudspeaker 302 emits a voice prompt.

[0055] Afterwards, the vehicle drives the left front wheel into the guide figure-eight of the integrated guide 7 according to the display of the front wheel guide convex mirror 5.

[0056] Finally, when the front of the car continues to move forward and blocks the vehicle from reaching the photoelectric sensor 1, the display screen 301 of the sound and light controller 3 shows "stop" and the loudspeaker 302 issues a voice prompt.

[0057] When the vehicle drives out of the space, and the front of the vehicle blocks the photoelectric sensor 2, the display screen 301 displays "backward" and the loudspeaker 302 issues a voice prompt.

[0058] Step 2, Payment Process:

[0059] First, when the front of the vehicle blocks the vehicle from entering the photoelectric sensor 1, and does not block the vehicle from overtaking the photoelectric sensor 2 and the ground induction coil has a signal output, the payment conditions are met.

[0060] Afterwards, the vehicle is scanned for payment or the car wash coupon is redeemed. The sound and light controller 3 prompts and broadcasts car wash precautions, the content of which is consistent with the content on the prompt curtain 403.

[0061] Step 3, self-service section conveyor transport:

[0062] First, after payment is completed, the barrier gate 402 automatically lifts, and the self-service section auxiliary conveyor 6 starts;

[0063] Then, the self-service auxiliary conveyor 6 pushes the right front wheel of the vehicle forward to transport the vehicle. When the push rod of the self-service auxiliary conveyor 6 flips to the bottom, it stops. When transporting forward, the right front wheel passes through the transition guide plate 9. At this time, the front of the vehicle has entered the car wash machine body.

[0064] Finally, after the vehicle enters the car wash machine, the monorail single-chain conveyor 13 starts and drives the vehicle forward.

[0065] Step 4, Cleaning Operation: The cleaning equipment inside the car wash machine is started to begin cleaning the vehicle;

[0066] Among them, at least four side anti-collision bars are added at the entrance and inside of the car wash machine body. The side anti-collision bars are located on the side away from the monorail single chain conveyor 13; effectively preventing vehicles from derailing and causing damage.

[0067] Step 5, Exit: After the vehicle is cleaned, the sound and light controller 3 will display and announce that the vehicle should be driven away as soon as possible;

[0068] Two pairs of anti-rear-end collision photoelectric sensors are installed at the exit of the car wash machine. When any one or both pairs of anti-rear-end collision photoelectric sensors are blocked, it is determined that there is a vehicle stuck at the exit, and the sound and light controller 3 issues a command to stop working.

[0069] This invention, through the coordination of multiple limiting structures and guiding devices, facilitates the driver's observation of the position, improves the parking accuracy in front of the car wash machine, and enables automatic adjustment to ensure that the vehicle can accurately and automatically move into the car wash machine body and complete the washing operation. It not only achieves high automation and unattended operation but also high car washing efficiency. Furthermore, the overall length of the inlet conveyor mechanism of this invention is only a minimum of 1.5 meters, while existing similar equipment requires the left front wheel to be dragged first, followed by the left rear wheel, which necessitates an additional 3.5 meters of inlet length in front of the car wash machine. Therefore, this invention has a more rational layout, a more compact structure, and effectively reduces the required length.

[0070] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0071] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
