Description

Technical Field

[0001] This invention relates to the field of car wash equipment, and more specifically, to a reciprocating double-arm contactless car wash equipment. Background Technology

[0002] Car wash machines primarily use computer-controlled brushes and high-pressure water to automatically clean cars. Reciprocating car wash machines, also known as gantry reciprocating car wash machines or gantry machines, were first invented by Americans, but their commercialization was largely achieved by the Japanese.

[0003] Current dual-arm reciprocating non-contact car wash equipment cleans the vehicle surface by rinsing it with arms. However, it often requires high water pressure, and when the water pressure is insufficient, the water output and cleaning effect of many car wash equipment are poor, affecting the removal of foam and stains from the vehicle surface. Summary of the Invention

[0004] This invention provides a reciprocating double-arm contactless car wash device, which solves the technical problem of insufficient water pressure in related car wash devices.

[0005] According to one aspect of the present invention, a reciprocating double-arm contactless car wash device is provided, including a bracket and a car wash arm mechanism disposed on the bracket, the car wash arm mechanism being movable along the length direction of the bracket, and the car wash arm mechanism including an arm body unit for thoroughly cleaning a car located within the bracket, the distance between the arm body unit and the outer surface of the car being adjustable. The arm unit includes an adjusting motor, a transmission gear plate, and an adjustable arm. The adjusting motor is installed in the inner wall of the car wash arm mechanism, and the output shaft of the adjusting motor is equipped with a drive gear plate. The transmission gear plate is installed at the top of the adjustable arm, and the drive gear plate and the transmission gear plate are connected by transmission.

The inner wall of the adjustable arm is provided with a number of nozzles distributed along the axis of the arm body. The adjustable arm is a hollow structure, and the ends of the nozzles extend into the interior of the adjustable arm. The ends of the nozzles are connected to an adjusting component, which drives the nozzles to move along their axial direction, so that the length of the part of the nozzles extending out of the surface of the adjustable arm body changes.

[0006] Furthermore, the car wash arm mechanism also includes a wing plate, which has a basin-shaped vertical cross-section structure, and the two ends of the wing plate are movably connected to the upper surface of the bracket.

[0007] Furthermore, the top two sides of the bracket are provided with driving components, and the driving components are connected to the side wall of the wing plate. The driving components are used to drive the wing plate to move along the length direction of the bracket.

[0008] Furthermore, sliding frames are installed on the bottom sides of both ends of the wing plate, and the sliding frames are slidably connected to the top outer wall of the support.

[0009] Furthermore, a dryer is provided on one side of the wing plate, and the output end of the dryer is aligned with the height direction of the support.

[0010] Furthermore: the bottom of the wing plate is provided with a storage box, and the storage box is provided with several liquid tanks and a liquid pump. The liquid pump is used to extract the liquid inside the liquid tank and deliver it to the adjustable arm.

[0011] Furthermore: the adjusting member includes a top block and a restoring spring. The top block has a trapezoidal structure, and the end of the nozzle has a beveled structure. The end of the nozzle abuts against the outer surface of the top block.

[0019] Example 1 See Figures 1-7 As shown, a reciprocating double-arm contactless car wash equipment includes a support 200 and a car wash arm mechanism 400 disposed on the support 200. The car wash arm mechanism 400 moves along the length direction of the support 200, and the car wash arm mechanism 400 includes an arm body unit 430. The arm body unit 430 is used to thoroughly clean the car located inside the support 200, and the distance between the arm body unit 430 and the outer surface of the car is adjustable. The drive component 300 drives the car wash arm mechanism 400. The drive component 300 includes, but is not limited to, a drive motor, a transmission sprocket and a transmission chain. The transmission sprocket is installed on the end side of the car wash arm mechanism 400, the transmission chain is installed on the outer wall of the transmission sprocket, and the output shaft of the drive motor is installed on the transmission sprocket located at its end. The arm unit 430 includes an adjusting motor 431, a transmission gear plate 432, and an adjustable arm 433. The adjusting motor 431 is installed in the inner wall of the car wash arm mechanism 400, and a drive gear plate is installed on the output shaft of the adjusting motor 431. The transmission gear plate 432 is installed on the top of the adjustable arm 433. The drive gear plate and the transmission gear plate 432 are connected by transmission. The adjusting motor 431 drives the transmission gear plate 432 and the adjustable arm 433 to rotate through the drive gear plate. The inner wall of the adjustable arm 433 is provided with a number of nozzles 433c distributed along the axis of the arm body. The adjustable arm 433 is a hollow structure, and the end of the nozzle 433c extends into the interior of the adjustable arm 433. The end of the nozzle 433c is connected to an adjusting member. The adjusting member drives the nozzle 433c to move along its axial direction, so that the length of the part of the nozzle 433c extending out of the surface of the adjustable arm 433 changes.

[0020] The car wash arm mechanism 400 also includes a wing plate 410, which has a basin-shaped vertical cross-section structure, and the two ends of the wing plate 410 are movably connected to the upper surface of the bracket 200.

[0021] Both sides of the top of the bracket 200 are provided with driving components 300, and the driving components 300 are connected to the side wall of the wing plate 410. The driving components 300 are used to drive the wing plate 410 to move along the length of the bracket 200.

[0022] Sliding brackets 450 are installed on the bottom sides of both ends of the wing plate 410, and the sliding brackets 450 are slidably connected to the top outer wall of the bracket 200.

[0023] A dryer 420 is provided on one side of the wing plate 410, and the output end of the dryer 420 is aligned with the height direction of the bracket 200.

[0024] The bottom of the wing plate 410 is provided with a storage box 440, and the storage box 440 is provided with several liquid tanks and a liquid pump 460. The liquid pump 460 is used to extract the liquid inside the liquid tanks and deliver it to the adjustable arm 433.

[0025] The adjusting component includes a top block 433e and a restoring spring 433d. The top block 433e has a trapezoidal structure, and the end of the nozzle 433c has a beveled structure. The end of the nozzle 433c abuts against the outer surface of the top block 433e. The restoring spring 433d is installed on the inner wall of the adjustable arm 433 and is used to provide a restoring force for stretching the top block 433e.

[0026] The top block 433e has a groove at its end, and the groove is connected to the liquid inlet at the end of the nozzle 433c.

[0027] The bracket 200 is equipped with a controller 500 near the direction the car is entering. The controller 500 is used to input car information and washing settings information, and to control the movement of the car wash arm mechanism 400.

[0028] It also includes a guide base 100, on which a guide protrusion is provided. The guide protrusion is used to guide the vehicle to drive into the interior of the bracket 200. The guide base 100 has a drainage area inside the guide protrusion, which is used to collect car wash wastewater.

[0029] When the contactless car wash equipment is in use, the vehicle is guided through one end of the base 100 and the vehicle information and vehicle washing settings, such as washing time and foam spraying amount, are input through the controller 500, which can be adjusted by the controller 500 to make the car wash arm mechanism 400 execute. The vehicle stops on the guide protrusion on the guide base 100. At this time, the car wash arm mechanism 400 begins to wash the vehicle. The storage tank 440 inside the car wash arm mechanism 400 contains foam water and clean water. The foam water is used to soften and carry a large amount of foam to spray onto the surface of the vehicle, so that the dust on the surface can be carried away by the foam water and flowed down. After subsequent rinsing with clean water, the vehicle surface is rinsed and cleaned. After repeated multiple times, the vehicle surface achieves a good cleaning effect. Specifically, the cleaning operation of the car wash arm mechanism 400 is as follows: the liquid in the storage device is drawn by the liquid pump 460 and transported to the adjustable arm 433. When passing through the arm body, due to the liquid pressure, the top block 433e moves along the arm body axis, causing it to move at the front end of the nozzle 433c. This causes the nozzle 433c to be squeezed out of the arm body and aligned with the orifice of the nozzle 433c, allowing the liquid to be sprayed out from the nozzle 433c, thus cleaning the vehicle surface. Since the output is continuous, the top block 433e will be fully pushed out when the water pressure of the nozzle 433c is high, achieving efficient water spraying. When the water pressure is low, the water pressure will persist until it reaches a certain standard, at which point the nozzle 433c will be sprayed out. Then, the top block 433e will be pulled back under the action of the return spring 433d. At this time, the nozzle 433c will spring back, forming intermittent standard pressure spraying. The extension and retraction of the nozzle 433c achieves intermittent rinsing of the vehicle body surface, improving the cleaning effect when the water pressure is low. When cleaning with low water pressure, the telescopic part 433a can be retracted to shorten the distance between the nozzle 433c on the adjustable arm 433 and the vehicle surface, thereby increasing the water pressure and ensuring the cleaning effect. The telescopic part 433a is connected to the fixed part 433b. The adjustable arm 433 is "L" shaped, and the telescopic part 433a is the short arm end. The telescopic part 433a can adjust the distance between the long arm end and the vehicle surface. Specifically, the telescopic part 433a can be a stepper motor and a lead screw. The output shaft of the stepper motor is installed at one end of the lead screw. The telescopic part 433a is a sleeve structure. A connecting block is installed on the inner wall of the sleeve, and the outer wall of the lead screw is engaged with the inner wall of the connecting block. Simultaneously, during the washing process, the two arms can be operated in single-arm or double-arm mode. Double-arm operation means that the two car wash arm mechanisms 400 on both sides move relative to each other or towards each other, driving the adjustable arm 433 to move along the axial direction. At the same time, when passing through the front and rear of the vehicle, the adjustment motor 431 drives the transmission gear plate 432, and the transmission gear plate 432 drives the adjustable arm 433 to rotate 180° through the gear set, thereby achieving steering and realizing full coverage of vehicle surface cleaning. After cleaning, the surface is rinsed multiple times with clean water until it is clean. Then, a 420mm air dryer is used to blow water vertically to remove any remaining water from the vehicle's exterior.
