[0002] With the continuous improvement of living standards, my country's automobile industry has developed rapidly in recent years, and cars have become ubiquitous. Consequently, the car wash industry has also experienced rapid growth. Regular car washing helps remove dirt, protects the paint, prevents rust, and improves driving comfort. Self-service car washes are not limited by time or location, have no additional labor costs, are relatively inexpensive, and offer a sense of participation and enjoyment, making them increasingly popular among car owners.

[0003] Existing car wash machines typically use 380V motors for speed reduction. When the motor burns out or is damaged for other reasons, coupled with the fact that car wash locations are wet, there is a risk of electric shock. Furthermore, traditional car wash machines, driven by 380V motors, have heavy motor equipment, making it impossible for a single person to complete replacement and repair work, resulting in high maintenance costs.

[0004] Therefore, there is an urgent need to design a half-width, low-pressure, fully automatic, contactless, and wipe-free car wash machine to overcome the shortcomings of one or more of the existing technologies. Utility Model Content

[0006] In a preferred embodiment, the output end of the 24V rotary motor is connected to a rotating disk, and the rotating arm is connected to the output end of the rotating disk. The rotating disk is used to change the output speed and output direction of the rotary motor.

[0007] In a preferred embodiment, the output end of the stroke motor is connected to a coaxial steering gear, and the two sides of the coaxial steering gear are respectively coaxially connected to a first rotating shaft, and the driving wheel is located at the end of the rotating shaft away from the coaxial steering gear.

[0008] In a preferred embodiment, one end of the shaft connected to the driving wheel is further provided with a synchronizing gear, and the synchronizing gear is connected to a second shaft, both ends of which are also provided with the driving wheel.

[0021] like Figures 1-2 As shown, this utility model provides a half-width 24V automatic car wash machine, characterized in that it includes: a gantry frame 10, with a car wash machine main unit 11 movably mounted on the top of the gantry frame 10. The car wash machine main unit 11 contains a 24V rotary motor 14 and a 24V stroke motor 15. The output end of the 24V rotary motor 14 is driven by a rotating arm 13, which is located in the middle of the gantry frame 10. The 24V rotary motor 14 drives the rotating arm 13 to rotate within a predetermined angle. The rotating arm 13 is equipped with several spray heads 131. The car wash machine main unit 11 is also fixedly connected to an air knife bracket 12, and the rotating arm 13 is located within the range of the air knife bracket 12. The side wall of the air knife bracket 12 is also provided with several air holes (not shown in the figure). The 24V stroke motor 15 is driven by a traveling wheel 153. The 24V stroke motor 15 drives the traveling wheel 153 to rotate and drive the car wash machine main unit 11 to move on the gantry 10. The car wash machine main unit 11 is also provided with a foam liquid tank 18. The foam liquid tank 18 is connected to the spray head 131. The car wash machine main unit 11 is also provided with a foam liquid booster pump 16 and a 24V air pump 17. The foam liquid booster pump 16 is used to spray foam liquid from the spray head 131. The 24V air pump 17 is used to add air to the foam liquid tank 18. The spray head 131 is also connected to a water source.

[0022] Furthermore, in this embodiment, the output end of the 24V rotary motor 14 is connected to a rotating disk 141, and the rotating arm 13 is connected to the output end of the rotating disk 141. The rotating disk 141 is used to change the output speed and output direction of the 24V rotary motor.

[0023] Furthermore, in this embodiment, the output end of the stroke motor is connected to a coaxial steering gear 151, and the two sides of the coaxial steering gear 151 are respectively coaxially connected to a first rotating shaft 152, and the driving wheel 153 is located at the end of the rotating shaft away from the coaxial steering gear 151.

[0024] Furthermore, in this embodiment, a synchronous gear 154 is also provided at one end of the rotating shaft connected to the driving wheel 153. The synchronous gear 154 is connected to a second rotating shaft 155, and the driving wheel 153 is also provided at both ends of the second rotating shaft 155.

[0025] Furthermore, in this embodiment, the car wash machine main unit 11 is also provided with a water wax tank 19 and a water wax booster pump 20. The water wax tank 19 is connected to the spray head 131, and the water wax booster pump 20 is used to increase the spray pressure of the water wax.

[0026] Furthermore, in this embodiment, a number of detection sensors (not shown in the figure) are also provided on the outer side of the gantry frame 10;

[0027] Specifically, the car wash machine main unit 11 is movably mounted on top of the gantry frame 10. The main unit 11 contains a 24V stroke motor 15, the output of which is connected to a coaxial steering gear 151. First rotating shafts 152 are coaxially connected to both sides of the coaxial steering gear 151. These first rotating shafts 152 are located on top of the main unit 11. A travel wheel 153 is connected to the end of the first rotating shaft 152 furthest from the coaxial steering gear 151. The travel wheel 153 is connected to an external mounting bracket. The main unit 11 reciprocates along the gantry frame 10 by controlling the rotation of the travel wheel 153. To improve the stability of the car wash machine main unit 11, a synchronous gear 154 is provided at one end of the first rotating shaft 152 where the traveling wheel 153 is located. This synchronous gear 154 is connected to a second rotating shaft 155 via a synchronous belt drive. The second rotating shaft 155 is located at the bottom of the car wash machine main unit 11, and both ends of the second rotating shaft 155 are also provided with traveling wheels 153. This improves the stability of the car wash machine main unit 11's movement through the two traveling wheels 153 at each end. A 24V rotary motor 14 is also provided inside the car wash machine main unit 11. The output end of the 24V rotary motor 14 is connected to a rotating disk 141. The output direction of the 24V rotary motor 14 can be switched. The output end of the rotary disk 141 is connected to a rotating arm 13, which is located in the middle of the gantry frame 10 and rotates within the gantry frame 10 through the drive of the 24V rotary motor 14. The rotation angle is preferably 180°. The rotating arm 13 is equipped with several spray heads 131, which are connected to an external water source. To increase the water flow pressure of the spray heads 131, a high-pressure water pump is connected to the spray heads 131. The high-pressure water pump increases the outlet water pressure of the spray heads 131, so that the water pressure increases when the spray heads 131 are spraying water. The presence of foam impacts the surface of the vehicle, cleaning it through impact force, thus eliminating the need for wiping equipment such as cloths. To enhance cleaning power, a foam liquid tank 18 is also provided inside the car wash machine main unit 11. The foam liquid tank 18 is connected to the spray head 131, and the foam liquid tank 18 is also connected to a foam liquid booster pump 16, which causes the cleaning foam inside to be sprayed out from the spray head 131 under pressure and has a certain coverage area. A 24V air pump 17 is used to add air to the foam liquid tank 18, so that the foam liquid is foamy when sprayed and the sprayed foam is finer. The cleaning foam is preferably a cleaning agent that can automatically decompose stains.To prevent water droplets from remaining on the car body after washing and causing users to re-adhere to dust after driving out of the car wash machine, an air knife bracket 12 is fixedly connected to the main unit 11 of the car wash machine. The air knife bracket 12 has several air holes, and a high-pressure blower is connected to the air holes. The high-pressure blower compresses air and blows it out of the air holes, giving the blown air a certain pressure. This airflow blows away the water droplets. The high-pressure blower can also blow hot air to increase the evaporation rate of the water droplets. In order to improve the efficiency of removing water droplets from the air holes, the diameter of the air holes is preferably small, so that the blown air forms an air knife. This allows for sufficient pressure to blow away water droplets from the vehicle. To enhance the functionality of the car wash machine, a water wax tank 19 and a water wax booster pump 20 are also provided inside the main unit 11. The water wax tank 19 is connected to the spray head 131, and water wax can be sprayed out through the spray head 131 after cleaning. In this application, several detection sensors are also provided on the outer side of the air knife bracket 12. These detection sensors are used to identify the current status of each device. The detection sensors include, but are not limited to, inductive loops, flushing solenoid valves, and photoelectric switches, which are common existing technologies and will not be described in detail here.

[0028] It should be noted that both the foam liquid booster pump 16 and the water wax booster pump 20 are powered by 24V.

[0029] Work process:

[0030] After a vehicle enters the car wash's barrier gate and pays the fee, the ground induction coil powers the car wash machine's electrical control cabinet, activating the water pump. As the car passes the undercarriage washing photoelectric switch, the undercarriage washing solenoid valve is activated, initiating undercarriage washing. Once the vehicle passes the photoelectric switch again, the undercarriage washing solenoid valve closes, stopping the undercarriage washing process. The vehicle then enters the washing area, where a photoelectric switch determines if washing conditions are met, such as whether the vehicle is parked correctly. If conditions are not met, a voice prompt is given; if conditions are met, a countdown begins. After the countdown completes, the washing process is activated. The solenoid valve pre-washes the vehicle with water, removing most of the mud, sand, large dust particles, and debris. At this time, the 24V stroke motor 15 operates, driving the car wash main unit 11 and rotating arm 13 to move horizontally, cleaning the corresponding side until the photoelectric switch no longer senses the vehicle. Then, the 24V stroke motor 15 stops, and the 24V rotary motor 14 starts, driving the rotating arm 13 to rotate around the vehicle, cleaning one end of the vehicle. After the rotating arm 13 has rotated 180°, the photoelectric switch shuts off the 24V rotary motor 14, and the 24V stroke motor 15 reverses, driving the rotating arm 13 back to its starting position. Moving the vehicle to the other side for cleaning, the 24V stroke motor 15 stops when the photoelectric switch detects that the designated position has been reached. The 24V rotary motor 14 is then restarted, controlling the rotating arm 13 to reverse. After reversing to the correct position, the photoelectric switch shuts off the rotary motor, completing the pre-cleaning. The 24V stroke motor 15 then resets until the photoelectric switch no longer detects the vehicle, at which point it stops. The spray nozzles 131 then spray cleaning foam, repeating the above stroke around the vehicle until one revolution is completed. Afterward, a 60-second pause is taken to allow the cleaning foam to decompose on the vehicle. After the surface stains are removed and the washing process is complete, the rinsing program is started, and the rinsing solenoid valve is activated to rinse the vehicle with water. The stroke is the same as described above. After one revolution, it stops and the water wax booster pump 20 is started to spray water wax onto the vehicle. This process also runs for one revolution. After one revolution, wait 15 seconds and then start the drying program. The 24V air pump 17 is started to dry the vehicle. The 24V stroke motor 15 drives the air knife bracket 12 to run back and forth in a cycle three times until the water is dried. Then the vehicle is removed from the gantry 10, the inductor coil is triggered, and the power of the car wash machine is turned off. The car wash is now complete.

[0031] In summary, this application reduces the size of the equipment and the weight of accessories by using low-voltage devices for all drive components, thereby reducing maintenance costs. At the same time, low-voltage devices consume less electricity and have lower electricity costs. Furthermore, the overall cost of the equipment is lower due to the use of low-voltage devices, which is more conducive to market promotion. Using low-voltage devices can also effectively avoid the risk of electric shock and improve safety during use.

[0032] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
