Description

Technical Field

[0001] This invention relates to the field of mechanical technology, specifically to car wash and detailing technology. Background Technology

[0002] With the rapid growth of car ownership in China, the car wash industry has developed rapidly. In order to improve car wash efficiency and reduce the labor intensity of car washing, intelligent car wash workshops equipped with car wash robotic arms have become widespread.

[0003] Car wash equipment with robotic arms can simultaneously clean the front, rear, or both sides of a car, or even more robotic arms. These robotic arms occupy space in the wash bay, making it difficult to store larger items in the wash bay outside of car wash hours, resulting in wasted space.

[0004] In first- and second-tier cities, and even some popular cities, the cost of renting houses is very high. The space in car wash workshops is not used effectively, which increases the cost of the car wash industry and reduces its efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a car wash system with a built-in storage compartment to solve at least one of the above-mentioned technical problems.

[0006] The technical problem solved by this invention can be achieved by the following technical solutions:

[0007] The storage compartment-embedded car wash system includes a washing bay with a track on the top of the washing bay, the track being connected to a traveling mechanism that can move back and forth; it also includes a high-pressure water pump system, the water outlet of which is connected to a high-pressure water nozzle; and it also includes a car wash control system, which controls and connects to moving parts with power devices.

[0008] The car wash actuator is connected to the lower part of the walking mechanism via a rotatable rotating mechanism;

[0009] The car wash actuator includes a horizontally telescopic mechanism, and a mounting bracket is connected to the end of the telescopic mechanism;

[0010] It also includes a telescopic device as a telescopic car wash robotic arm, with a rotating mechanism installed at the end of the car wash robotic arm, and a high-pressure water nozzle connected to the rotating mechanism.

[0011] The mounting bracket is connected to the car wash robotic arm via a lifting drive mechanism that drives the car wash robotic arm to rotate and rise.

[0012] The car wash workshop floor is equipped with car wash bays. A drainage ditch is set in the middle of the car wash bay along the front-to-back direction. A drain outlet is set at the bottom of the ditch and connected to a drainage pipe. A turbidity sensor is installed in the drainage pipe. The turbidity sensor signal is connected to the car wash control system, which controls the output of high-pressure water from the high-pressure water pump system.

[0013] In the above design, the rotating mechanism can drive the car wash execution mechanism to rotate, and by rotating the car wash execution mechanism, the entire vehicle can be cleaned.

[0014] The car wash actuator includes a horizontal telescopic mechanism. The function of the telescopic mechanism is to adapt to the size of different car models by extending and retracting, so that the outlet of the high-pressure water nozzle and the car body are at the optimal cleaning distance, so that the water flow can be concentrated and avoid dispersion that would result in insufficient water pressure and loss of impact force to wash away dirt.

[0015] There is a lifting drive mechanism between the mounting bracket and the car wash robotic arm, which drives the car wash robotic arm to rotate and thus raise the car wash robotic arm to the upper part of the car wash workshop. After the car wash robotic arm is raised to the upper part of the car wash workshop, the space under the car wash workshop can be freed up. Its beneficial effect is that it creates storage space, improves space utilization, and generates economic benefits.

[0016] The advantages of a telescopic car wash robot arm are twofold. First, the telescopic mechanism allows for a wider range of adjustment of the high-pressure water nozzles. Second, the robot arm occupies less space when retracted, and its rotation and lifting are less strenuous, allowing for faster raising.

[0017] In the above design, a drainage ditch is set in the middle of the car wash area. A turbidity sensor is installed in the drainage pipe of the ditch. Through the turbidity sensor, the car wash control system can detect the cleanliness of the car wash and stop the high-pressure water output of the high-pressure water pump system in time. Its beneficial effects are to improve the cleanliness of the car wash, save the consumption of car wash water resources, and improve the economic efficiency of the car wash.

[0018] Furthermore, the car wash robotic arm includes a metal tube as an upper mechanical arm, and another metal tube is sleeved on the upper mechanical arm. The other metal tube serves as a mechanical forearm that can slide up and down along the upper mechanical arm. The end of the mechanical forearm is connected to the high-pressure water nozzle through a rotating mechanism.

[0019] The lifting drive mechanism includes a push rod mechanism, which is mounted on a mounting bracket;

[0020] The telescopic rod end of the push rod mechanism is rotatably connected to the upper end of the mechanical upper arm;

[0021] The upper part of the mechanical arm is rotatably connected to the mounting bracket, which becomes the pivot point for the mechanical arm to rotate and lift.

[0022] The telescopic rod of the push rod mechanism is linked to the rotation of the upper mechanical arm around the pivot point, so that the mechanical forearm can be in a raised state and a lowered state.

[0023] The upper and forearm of the machine are made of aluminum alloy tubing.

[0024] In the above design, the car wash robotic arm has a rotatable fulcrum mounted on a mounting bracket at the upper part of the upper arm. When the telescopic rod of the push rod mechanism retracts, the telescopic rod pulls the upper arm to rotate around the fulcrum, raising the front arm of the robotic arm to a higher position in the car wash area, thereby freeing up space for storage and improving the space utilization of the car wash area. When the telescopic rod of the push rod mechanism extends, the telescopic rod pushes the upper arm to rotate around the fulcrum, lowering the front arm of the robotic arm for car washing operations.

[0025] In the above design, the upper mechanical arm and the forearm are made of aluminum alloy metal tubes. The advantage of this is that it reduces the weight of the car wash mechanical arm and makes it easier for the lifting drive mechanism to raise the car wash mechanical arm.

[0026] Furthermore, the car wash robotic arm is also equipped with a limiting device to restrict the sliding of the robotic forearm on the robotic upper arm;

[0027] The limiting device includes through holes arranged in a straight line along at least 75-90% of the length of the tube wall of the upper arm of the machine, serving as limiting holes, with the spacing between the limiting holes being 10-20 mm.

[0028] It also includes a pin seat on the tube wall facing forward of the mechanical forearm, and a pin on the pin seat that is inserted into the upper limit hole of the mechanical upper arm.

[0029] Slide grooves are cut along a straight line on the tube walls on both sides of the mechanical upper arm;

[0030] The inner wall of the mechanical forearm is provided with at least two sliders that are adapted to the sliding grooves on both sides of the mechanical upper arm.

[0031] In the above design, the limiting mechanism adopts the pin limiting method. Its advantages are that the pin limiting method has the characteristics of simple structure, easy processing, and firm limiting. The arrangement interval of the limiting holes is 10 to 15 mm, which allows for more adjustable positions and can meet the needs of washing various car models.

[0032] In the above design, the mechanical upper arm and the mechanical forearm are connected by a slide groove and a slider. The purpose of this is to guide the mechanical forearm to slide on the mechanical upper arm so that the pin and the limiting hole are kept in a straight line, making it easy for the pin to be inserted into the limiting hole for limiting.

[0033] Furthermore, a rotating device is also provided between the telescopic mechanism and the mounting bracket;

[0034] The rotating device includes a mounting bracket and a bidirectional motor. The mounting bracket is installed at the end of the telescopic mechanism, and the bidirectional motor is installed on the mounting bracket. The output shaft of the bidirectional motor is connected to the mounting bracket and can rotate left and right.

[0035] In the above design, a rotating device is installed between the telescopic mechanism and the mounting bracket, which uses a bidirectional motor to drive the mounting bracket to rotate left and right. The mounting bracket is connected to a car wash robotic arm, and a high-pressure water nozzle is installed at the end of the robotic arm. The rotating device, in conjunction with the high-pressure water nozzle, can rotate left and right in the direction of car washing, achieving a scanning rinsing method with small nozzles, small water volume, and high water pressure. This rinsing method has strong rinsing force and can remove stubborn dirt. Its advantages include water and electricity savings, lower requirements for the high-pressure water pump's output and pressure, resulting in a lower cost for the high-pressure water pump and cost savings. Furthermore, the high-pressure water pump consumes little electricity during operation, saving energy. The small water volume and small nozzle operation can increase the car wash water pressure, thus improving the cleanliness of the car wash and enhancing its economic benefits.

[0036] Furthermore, the rotating mechanism includes a telescopic rod device, the telescopic rod of which is connected to a rotating rod that reciprocates up and down, the rotating rod being connected to a high-pressure water nozzle, and the telescopic rod device, in conjunction with the rotating rod, drives the high-pressure water nozzle to rotate up and down.

[0037] In the above design, the telescopic rod device drives the high-pressure water nozzle to rotate up and down, which has the beneficial effect of changing the rinsing part and rinsing angle of the high-pressure water flow, reducing dead corners in car washing, and improving the cleanliness of car washing.

[0038] Furthermore, it also includes an ultrasonic device for generating ultrasonic waves, the ultrasonic device comprising a transducer with piezoelectric ceramics and an ultrasonic signal generator for generating ultrasonic waves, the ultrasonic signal generator signal controlling the transducer.

[0039] The high-pressure water nozzle is surrounded by at least four transducers for ultrasonic devices.

[0040] The transducer emits ultrasonic waves in the direction of the high-pressure water nozzle. The ultrasonic device is activated while the car is being washed with water to clean the car body surface using ultrasonic cleaning.

[0041] In the above design, the fine water streams from the high-pressure water nozzles are locally atomized and expanded into a flushing water stream mixed with water vapor and water column under the action of ultrasound. The beneficial effects are that it can save water on the one hand and increase the area of ​​the flushing water stream on the other hand, thereby improving the cleaning effect of car washing.

[0042] In the above design, the transducer of the ultrasonic device is controlled to face the vehicle body when spraying water, at a distance of 1cm to 2cm from the vehicle body. A flexible bushing with a through hole in the middle is provided in front of the transducer of the ultrasonic device, and the thickness of the flexible bushing is set at 1mm to 2mm.

[0043] By bringing the transducer of the ultrasonic device close to the surface of the car body, ultrasonic waves are transmitted to the surface of the car body, making the car body an ultrasonic source. This generates an ultrasonic cavitation effect on the water film attached to the car body, thereby purifying the car body.

[0044] The flexible bushing serves to focus ultrasonic waves and prevent accidental contact with the vehicle body, thus avoiding damage to the vehicle body.

[0045] Furthermore, the high-pressure water nozzle adopts an ultrasonic spray cleaning system that uses ultrasonic high-pressure water jet rinsing for cleaning.

[0046] The ultrasonic spray cleaning system includes an ultrasonic device, which includes an ultrasonic signal generator and a piezoelectric ceramic as a transducer. The ultrasonic signal generator is connected to the piezoelectric ceramic. A through hole is provided in the middle of the piezoelectric ceramic to allow high-pressure water to pass through. The through hole pipe is connected to the outlet of the high-pressure water pump, thus becoming a high-pressure water nozzle.

[0047] While the high-pressure water nozzles spray water to wash the car, the ultrasonic device is activated to perform ultrasonic spray cleaning on the car body surface.

[0048] In the above design, in the ultrasonic spray cleaning system, the piezoelectric ceramic vibrates the high-pressure water to generate cavitation bubbles. When the high-pressure water mixed with cavitation bubbles is sprayed on the car body, the cavitation bubbles burst and generate shock waves that can penetrate into tiny gaps and pores, peeling off and removing stains, thus improving the cleanliness of the car wash.

[0049] Furthermore, it also includes an ultrasonic device for generating ultrasonic waves, which includes an ultrasonic signal generator and a piezoelectric ceramic as a transducer.

[0050] The car wash control system's signal control is connected to an ultrasonic signal generator, which in turn is connected to a piezoelectric ceramic. The piezoelectric ceramic is installed inside the pipe wall of the high-pressure water nozzle.

[0051] The car wash control system controls the high-pressure water pump to output high-pressure water while simultaneously activating the ultrasonic signal generator to perform ultrasonic high-pressure water rinsing and cleaning on the car body surface.

[0052] In the above design, the piezoelectric ceramic installed inside the high-pressure water nozzle performs ultrasonic vibration, forming cavitation bubbles in the high-pressure water. When the high-pressure water with cavitation bubbles washes over the car body, the cavitation bubbles burst and generate shock waves. The combination of high-pressure water washing and the shock waves from the bursting cavitation bubbles can enhance the cleaning effect.

[0053] Furthermore, there are at least two car wash actuators, which are connected to the left and right sides of the rotating mechanism.

[0054] In the above design, there are at least two car wash actuators connected to the left and right sides of the rotating mechanism. The benefits are as follows: First, it maintains the balance of the two sides of the rotating mechanism and prevents the unevenness from causing increased wear on the guide rail and the traveling mechanism. Second, by setting the car wash actuators on the left and right sides of the rotating mechanism, the two sides of the vehicle body or the front and rear of the vehicle can be cleaned at the same time, thus improving the cleaning efficiency.

[0055] Furthermore, the floor of the washing workshop is covered with a perforated plate, which is flush with the ground.

[0056] The ground beneath the slab slopes towards the ditch from both sides.

[0057] A first support plate and a second support plate are respectively installed at both ends of the ditch;

[0058] It also includes a water pipe as a sprinkler pipe, which is set in the middle of the ditch, and at least 4 meters of the upper part of the sprinkler pipe is equipped with water spray nozzles that spray upwards.

[0059] The water nozzles are arranged in a straight line, with a nozzle diameter of 6.5 to 7.5 mm and a spacing of 20 to 50 mm.

[0060] One end of the spray pipe has a water inlet, called the water inlet end. The water inlet end passes through the first support plate and is rotatably connected to the first support plate. The water inlet end passing through the first support plate is rotatably inserted into the inner wall of a water supply pipe that connects to the outlet of a high-pressure water pump system. A water-sealing shaft seal is provided between the outer wall of the water inlet end and the inner wall of the water supply pipe.

[0061] The other end of the spray pipe is closed, which is called the closed end. The closed end passes through the second support plate and is rotatably connected to the second support plate.

[0062] The flat plate is provided with through slots corresponding to the positions of the first support plate, the second support plate, and the spray pipe, allowing the first support plate, the second support plate, and the spray pipe to protrude from the flat plate;

[0063] It also includes a reciprocating rotation mechanism, which is linked to the spray pipe to rotate back and forth;

[0064] The reciprocating rotation mechanism includes a geared motor device with an integrated reduction mechanism, and a reciprocating linkage mechanism. The output shaft of the geared motor device is connected to the closed end through the reciprocating linkage mechanism.

[0065] In the above design, the purpose of laying a flat plate with grid holes is to prevent large debris from falling into the groove and clogging the drainage of the groove; the flat plate is flush with the ground to make it easy for vehicles to enter and exit the car wash area; the ground under the flat plate slopes from the edge towards the groove, which facilitates the collection of sewage into the groove for unified discharge; the beneficial effect of the spray pipe protruding from the flat plate is that the high-pressure water flow will not be blocked by the flat plate during car washing.

[0066] In the above design, the spray pipe is installed in the ditch, and the water inlet end of the spray pipe is rotatably connected to the water supply pipe of the high-pressure water pump system. A water-sealing shaft seal is installed at the connection to prevent high-pressure water from overflowing from the connection. The high-pressure water washes the underside of the vehicle through the upward-facing nozzles arranged on the spray pipe. The reciprocating rotation mechanism links the spray pipe to rotate left and right. Its beneficial effect is that the left and right rotation washing of the underside of the vehicle can thoroughly clean the entire bottom, prevent the chassis and pipeline from rusting, and ensure vehicle driving safety.

[0067] In the above design, the part of the spray pipe with nozzles is at least 4m long, which has the advantage that the length of the nozzles can be adapted to the length of the vehicle's bottom.

[0068] In the above design, the reciprocating rotation mechanism is linked to the spray pipe to rotate back and forth, guiding the nozzle to change the spray position and spray angle on the vehicle chassis, forming a spray zone for washing the bottom of the vehicle, thereby achieving the cleaning of the bottom of the vehicle.

[0069] In the above design, the reciprocating rotation mechanism uses a geared motor to connect the spray pipe through a reciprocating linkage mechanism to achieve reciprocating left and right rotation. Its advantages are that the geared motor provides power output for the reciprocating rotation, and the reciprocating linkage mechanism converts the circular rotation into a left and right rotation motion. The reciprocating linkage mechanism has the advantages of simple structure, stable reciprocating rotation effect, easy processing of the components constituting the reciprocating linkage mechanism, and low maintenance cost.

[0070] The present invention provides a rotating fulcrum mounted on a mounting bracket on the upper mechanical arm of the car wash robotic arm. When the push rod of the push rod mechanism retracts, it drives the car wash robotic arm to rotate clockwise around the rotating fulcrum, raising the car wash robotic arm to a higher position in the car wash workshop, thereby freeing up space for storage and improving the space utilization rate of the car wash workshop.

[0071] Its beneficial effects also lie in the fact that the combination of high-pressure water nozzles and ultrasonic generators forms an ultrasonic spray cleaning system. The ultrasonic spray cleaning system uses piezoelectric ceramics to form compressed bubbles in high-pressure water. When the high-pressure water washes the car body, the compressed bubbles burst and generate shock waves, which can penetrate into tiny gaps and cavities to peel off and remove stains, thus improving the cleanliness of the car wash.

[0072] Its beneficial effects also include the fact that the floor of the car wash has a water ditch, and a spray pipe with a high-pressure water nozzle is installed in the middle of the ditch. The spray pipe is connected to the output pipe of the high-pressure water pump system. The spray pipe is also linked to a reciprocating rotation mechanism to achieve left and right rotation. This allows the car underside to be cleaned without occupying the car wash space or affecting storage, thus improving the cleanliness of the car wash. Attached Figure Description

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0087] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0088] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in an embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0089] Reference Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, the storage compartment embedded car wash system includes a washing workshop 1, with a track on the top of the washing workshop 1, the track being connected to a walking mechanism 4 that can move back and forth; it also includes a high-pressure water pump system, the water outlet of the high-pressure water pump system being connected to a high-pressure water nozzle 19; and it also includes a car wash control system, the car wash control system controlling and connecting to movable parts with power devices.

[0090] The car wash actuator is connected to the lower part of the walking mechanism 4 via a rotatable rotating mechanism;

[0091] The car wash actuator includes a horizontally telescopic mechanism 5, and a mounting bracket 9 is connected to the end of the telescopic mechanism 5.

[0092] It also includes a telescopic device as a telescopic car wash robotic arm 7, with a rotating mechanism installed at the end of the car wash robotic arm 7, and a high-pressure water nozzle 19 connected to the rotating mechanism.

[0093] The mounting bracket 9 and the car wash robotic arm 7 are connected by a lifting drive mechanism that drives the car wash robotic arm 7 to rotate and rise.

[0094] The floor of the car wash workshop 1 is equipped with car wash positions 2. A drainage ditch 12 is provided in the middle of the car wash position 2 along the front-to-back direction. A drain outlet is provided at the bottom of the ditch 12. The drain outlet is connected to a drainage pipe. A turbidity sensor is installed in the drainage pipe. The turbidity sensor signal is connected to the car wash control system. The car wash control system controls the output of high-pressure water from the high-pressure water pump system.

[0095] In this embodiment, the rotating mechanism can drive the car wash execution mechanism to rotate, and by rotating the car wash execution mechanism, the entire vehicle can be cleaned.

[0096] The car wash actuator includes a horizontally telescopic mechanism 5. The function of the telescopic mechanism 5 is to adapt to the size of different car models by telescopically extending and retracting, so that the outlet of the high-pressure water nozzle 19 and the car body are at the optimal cleaning distance, so that the water flow can be concentrated and avoid dispersion that would lead to insufficient water pressure and loss of impact force to wash away dirt.

[0097] There is a lifting drive mechanism between the mounting bracket 9 and the car wash robotic arm 7 to drive the car wash robotic arm 7 to rotate, thereby raising the car wash robotic arm 7 to the upper part of the car wash workshop 1. After the car wash robotic arm 7 is raised to the upper part of the car wash workshop 1, the lower space of the car wash workshop 1 can be freed up. Its beneficial effect is to form storage space, improve space utilization, and generate economic benefits.

[0098] The benefits of the telescopic car wash arm 7 are that, firstly, the telescopic mechanism 5 allows for a wider adjustment range of the high-pressure water nozzle 19; secondly, the car wash arm 7 occupies less space when retracted, and when rotating and lifting the car wash arm 7, it requires less effort to rotate and lift, and the car wash arm 7 can be raised faster.

[0099] In this embodiment, a drainage ditch 12 is provided in the middle of the car wash position 2. A turbidity sensor is installed in the drainage pipe of the ditch 12. Through the turbidity sensor, the car wash control system can detect the cleanliness of the car wash and stop the high-pressure water output of the high-pressure water pump system in time. Its beneficial effect is to improve the cleanliness of the car wash, save the consumption of car wash water resources, and improve the economic benefits of car washing.

[0100] Reference Figure 2 , Figure 6 As shown, the car wash robotic arm 7 includes a metal tube as a mechanical upper arm 71, and another metal tube is sleeved on the mechanical upper arm 71. The other metal tube serves as a mechanical front arm 72 that can slide up and down along the mechanical upper arm 71. The end of the mechanical front arm 72 is connected to the high-pressure water nozzle 19 through a rotating mechanism.

[0101] The lifting drive mechanism includes a push rod mechanism 10, which is mounted on the mounting bracket 9;

[0102] The end of the telescopic rod of the push rod mechanism 10 is rotatably connected to the upper end of the mechanical upper arm 71;

[0103] The upper part of the mechanical arm 71 is rotatably connected to the mounting bracket 9, which becomes the pivot point 18 for the rotation and lifting of the car wash mechanical arm 7.

[0104] The telescopic rod of the push rod mechanism 10 is linked to the rotation of the upper mechanical arm 71 around the rotation fulcrum 18, so that the mechanical forearm 72 has a raised state and a lowered state.

[0105] The upper mechanical arm 71 and the forearm mechanical arm 72 are made of aluminum alloy metal tubes.

[0106] In this embodiment, the car wash robotic arm 7 has a rotatable fulcrum 18 mounted on the mounting bracket 9 on the upper part of the upper robotic arm 71. When the telescopic rod of the push rod mechanism 10 retracts, the telescopic rod pulls the upper robotic arm 71 to rotate around the fulcrum 18, raising the mechanical front arm 72 to the height of the car wash workshop 1, thereby freeing up space for storage and improving the space utilization of the car wash workshop 1. When the telescopic rod of the push rod mechanism 10 extends, the telescopic rod pushes the upper robotic arm 71 to rotate around the fulcrum 18, lowering the mechanical front arm 72 for car wash operations.

[0107] In this embodiment, the mechanical upper arm 71 and the mechanical forearm 72 are made of aluminum alloy metal tubes. The advantage of this is that it reduces the weight of the car wash mechanical arm 7 and makes it easier for the lifting drive mechanism to raise the car wash mechanical arm 7.

[0108] Reference Figure 3 , Figure 4 As shown, the car wash robotic arm 7 is also equipped with a limiting device to restrict the sliding of the robotic forearm 72 on the robotic upper arm 71.

[0109] The limiting device includes through holes 711 arranged in a straight line along at least 75 to 90% of the length of the tube wall of the mechanical upper arm 71 facing forward, with the spacing of the limiting holes 711 being 10 to 20 mm.

[0110] It also includes a pin seat 73 provided on the tube wall of the mechanical forearm 72 facing forward, and a pin 74 provided on the pin seat 73 for inserting into the upper limit hole 711 of the mechanical upper arm 71.

[0111] Slider blocks 721 and 712 are provided on the tube walls on both sides of the mechanical upper arm 71 along a straight line;

[0112] The inner wall of the mechanical forearm 72 is provided with at least two sliders that are adapted to the sliders 721712 on both sides of the mechanical upper arm 71.

[0113] In this embodiment, the limiting mechanism adopts the pin 74 limiting method. Its advantages are that the pin 74 limiting method has the characteristics of simple structure, easy processing, and firm limiting. The arrangement interval of the limiting holes 711 is 10-15 mm. This arrangement interval allows for more adjustable positions and can meet the needs of washing various car models.

[0114] In this embodiment, the mechanical upper arm 71 and the mechanical forearm 72 are connected by sliders 721 and 712. The function of the sliders is to guide the mechanical forearm 72 to slide on the mechanical upper arm 71, so that the pin 74 and the limiting hole 711 are kept in a straight line, making it easy for the pin 74 to be inserted into the limiting hole 711 for limiting.

[0115] Reference Figure 6 As shown, a rotating device is also provided between the telescopic mechanism 5 and the mounting bracket 9;

[0116] The rotating device includes a mounting bracket 6 and a bidirectional motor 8. The mounting bracket 6 is installed at the end of the telescopic mechanism 5, and the bidirectional motor 8 is installed on the mounting bracket 6. The output shaft of the bidirectional motor 8 is connected to the mounting bracket 9, which can rotate left and right.

[0117] In this embodiment, a rotating device is provided between the telescopic mechanism 5 and the mounting bracket 9, which uses a bidirectional motor 8 to drive the mounting bracket 9 to rotate left and right. The mounting bracket 9 is connected to a car wash robotic arm 7, and a high-pressure water nozzle 19 is installed at the end of the robotic arm 7. The rotating device, in conjunction with the high-pressure water nozzle 19, can rotate left and right in the direction of car washing, achieving a scanning rinsing method with small nozzles, small water volume, and high water pressure. This rinsing method has strong rinsing force and can remove stubborn dirt. Its advantages include water and electricity saving, low requirements for the high-pressure water pump's output and pressure, resulting in a lower cost for the high-pressure water pump and cost savings. Furthermore, the high-pressure water pump consumes little electricity during operation, saving energy. The small water volume and small nozzle operation method can increase the car wash water pressure, thus improving the cleanliness of the car wash and enhancing its economic benefits.

[0118] Reference Figure 5 As shown, the rotating mechanism includes a telescopic rod device 75. The telescopic rod of the telescopic rod device 75 is connected to a rotating rod 76 that reciprocates up and down. The rotating rod 76 is connected to a high-pressure water nozzle 19. The telescopic rod device 75, in conjunction with the rotating rod 76, drives the high-pressure water nozzle 19 to rotate up and down.

[0119] In this embodiment, the telescopic rod device 75 is linked to the rotating rod 76 to drive the high-pressure water nozzle 19 to rotate up and down. Its beneficial effect is to change the rinsing part and rinsing angle of the high-pressure water flow, reduce dead corners in car washing, and improve the cleanliness of car washing.

[0120] Example 1: Combination of high-pressure water nozzle 19 and ultrasonic generator:

[0121] Reference Figure 7 As shown, it also includes an ultrasonic device for generating ultrasonic waves. The ultrasonic device includes a transducer 20 with piezoelectric ceramic and an ultrasonic signal generator for generating ultrasonic waves. The ultrasonic signal generator signals control the transducer 20.

[0122] At least four transducers 20 with ultrasonic devices are provided around the high-pressure water nozzle 19;

[0123] The ultrasonic wave emitted by the transducer 20 is directed toward the water spray direction of the high-pressure water nozzle 19. The ultrasonic device is activated while the car is being washed with water to perform ultrasonic cleaning on the car body surface.

[0124] In this embodiment, the fine water stream spurted by the high-pressure water nozzle 19 is locally atomized and expanded into a rinsing water stream mixed with water vapor and water column under the action of ultrasound. Its beneficial effects are that it can save water on the one hand and increase the area of ​​the rinsing water stream on the other hand, thereby improving the cleaning effect of car washing.

[0125] In this embodiment, the transducer 20 of the ultrasonic device is controlled to face the vehicle body when spraying water, at a distance of 1cm to 2cm from the vehicle body. A flexible bushing with a through hole in the middle is provided in front of the transducer 20 of the ultrasonic device, and the thickness of the flexible bushing is set to 1mm to 2mm.

[0126] The transducer 20 of the ultrasonic device approaches the surface of the car body and transmits ultrasonic waves to the surface of the car body, making the car body an ultrasonic source. This generates an ultrasonic cavitation effect on the water film attached to the car body, thereby purifying the car body.

[0127] The flexible bushing serves to focus ultrasonic waves and prevent accidental contact with the vehicle body, thus avoiding damage to the vehicle body.

[0128] Example 2: Combination of high-pressure water nozzle 19 and ultrasonic generator:

[0129] The high-pressure water nozzle 19 adopts an ultrasonic spray cleaning system with ultrasonic high-pressure water jet flushing and cleaning.

[0130] The ultrasonic spray cleaning system includes an ultrasonic device, which includes an ultrasonic signal generator and a piezoelectric ceramic as a transducer 20. The ultrasonic signal generator is connected to the piezoelectric ceramic. A through hole is provided in the middle of the piezoelectric ceramic to allow high-pressure water to pass through. The through hole pipe is connected to the water outlet of the high-pressure water pump, and thus becomes a high-pressure water nozzle 19.

[0131] While the high-pressure water nozzle 19 sprays water to wash the car, the ultrasonic device is activated to perform ultrasonic spray cleaning on the car body surface.

[0132] In this embodiment, in the ultrasonic spray cleaning system, the piezoelectric ceramic vibrates the high-pressure water to generate cavitation bubbles. When the high-pressure water mixed with cavitation bubbles is sprayed on the car body, the cavitation bubbles burst and generate shock waves that can penetrate into tiny gaps and pores, peeling off and removing stains, thus improving the cleanliness of the car wash.

[0133] Example 3: Combination of high-pressure water nozzle 19 and ultrasonic generator:

[0134] It also includes an ultrasonic device that generates ultrasonic waves, the ultrasonic device including an ultrasonic signal generator and a piezoelectric ceramic as a transducer 20.

[0135] The car wash control system signal control is connected to an ultrasonic signal generator, and the ultrasonic signal generator signal is connected to a piezoelectric ceramic, which is installed inside the pipe wall of the high-pressure water nozzle 19.

[0136] The car wash control system controls the high-pressure water pump to output high-pressure water while simultaneously activating the ultrasonic signal generator to perform ultrasonic high-pressure water rinsing and cleaning on the car body surface.

[0137] In this embodiment, the piezoelectric ceramic installed inside the pipe wall of the high-pressure water nozzle 19 performs ultrasonic vibration, forming cavitation bubbles in the high-pressure water. When the high-pressure water with cavitation bubbles washes over the car body, the cavitation bubbles burst and generate shock waves. The combination of high-pressure water washing and the shock waves from the bursting cavitation bubbles can enhance the cleaning effect.

[0138] Reference Figure 1 , Figure 2 As shown, there are at least two car wash actuators, and the at least two car wash actuators are connected to the left and right sides of the rotating mechanism.

[0139] In this embodiment, there are at least two car wash actuators connected to the left and right sides of the rotating mechanism. The advantages are as follows: First, it maintains the balance of the two sides of the rotating mechanism and prevents the unevenness of the two sides from causing increased wear on the guide rail 3 and the traveling mechanism 4. Second, by setting the car wash actuators on the left and right sides of the rotating mechanism, the two sides of the vehicle body or the front and rear of the vehicle can be cleaned at the same time, thereby improving the cleaning efficiency.

[0140] Reference Figure 8 , Figure 9 As shown, a flat plate 11 with grid holes is laid on the floor of the washing workshop 1, and the flat plate 11 is flush with the floor.

[0141] The ground beneath the flat plate 11 slopes towards the ditch 12 from both the left and right sides.

[0142] A first support plate and a second support plate 14 are respectively installed at both ends of the ditch 12;

[0143] It also includes a water pipe as a spray pipe 13, which is located in the middle of the water ditch 12. At least 4m of the upper part of the spray pipe 13 is equipped with water spray nozzles with the water spray direction facing upward.

[0144] The water nozzles are arranged in a straight line, with a nozzle diameter of 6.5 to 7.5 mm and a spacing of 20 to 50 mm.

[0145] One end of the spray pipe 13 has a water inlet, referred to as the water inlet end. The water inlet end passes through the first support plate and is rotatably connected to the first support plate. The water inlet end passing through the first support plate is rotatably inserted into the inner wall of a water supply pipe that connects to the outlet of a high-pressure water pump system. A water-sealing shaft seal is provided between the outer wall of the water inlet end and the inner wall of the water supply pipe.

[0146] The other end of the spray pipe 13 is closed, referred to as the closed end. The closed end passes through the second support plate 14 and is rotatably connected to the second support plate 14.

[0147] The plate 11 is provided with a through groove corresponding to the positions of the first support plate, the second support plate 14 and the spray pipe 13, allowing the first support plate 14 and the spray pipe 13 to protrude from the plate 11.

[0148] It also includes a reciprocating rotation mechanism, which is linked to the spray pipe 13 to reciprocate;

[0149] The reciprocating rotation mechanism includes a geared motor device 16 with an integrated reduction mechanism, and a reciprocating linkage mechanism 17. The output shaft of the geared motor device 16 is connected to the closed end through the reciprocating linkage mechanism 17.

[0150] In this embodiment, a flat plate 11 with grid holes is laid to prevent large debris from falling into the groove and clogging the drainage. The flat plate 11 is flush with the ground, which makes it easy for vehicles to enter and exit the car wash position 2. The ground under the flat plate 11 slopes from the edge towards the groove, which facilitates the collection of sewage into the groove for unified discharge. The beneficial effect of the spray pipe 13 protruding from the flat plate 11 is that the high-pressure water flow will not be blocked by the flat plate 11 during car washing.

[0151] In this embodiment, the spray pipe 13 is installed in the water ditch 12. The water inlet end of the spray pipe 13 is rotatably connected to the water supply pipe of the high-pressure water pump system. A water-sealing shaft seal is provided at the connection to prevent high-pressure water from overflowing from the connection. The high-pressure water washes the underside of the vehicle through the upward-facing nozzles arranged on the spray pipe 13. The reciprocating rotation mechanism drives the spray pipe 13 to rotate left and right. Its beneficial effect is that the left and right rotation washing of the underside of the vehicle can thoroughly clean the entire bottom, prevent the chassis and pipes from rusting, and ensure vehicle driving safety.

[0152] In this embodiment, the portion of the spray pipe 13 with nozzles is at least 4m long, which has the advantage that the length of the nozzles can be adapted to the length of the vehicle's bottom.

[0153] In this embodiment, the reciprocating rotation mechanism is linked to the spray pipe 13 to rotate back and forth, guiding the nozzle to change the rinsing position and rinsing angle of the vehicle chassis, forming a spray zone for rinsing the bottom of the vehicle, thereby achieving the cleaning of the bottom of the vehicle.

[0154] In this embodiment, the reciprocating rotation mechanism uses a geared motor device 16 connected to the spray pipe 13 via a reciprocating linkage mechanism 17 to achieve reciprocating left and right rotation. Its advantages are that the geared motor device 16 provides power output for reciprocating rotation, and the reciprocating linkage mechanism 17 converts the circular rotation into a left and right rotation motion. The reciprocating linkage mechanism 17 has the advantages of simple structure, stable reciprocating rotation effect, easy processing of the components constituting the reciprocating linkage mechanism 17, and low maintenance cost.
