Description

Technical Field

[0001] The present invention relates to the field of intelligent car washing, and in particular to a telescopic intelligent car washing device and a car washing method. Background Art

[0002] With the continued rapid growth of car ownership, more and more car owners need convenient and efficient car wash services. Traditional manual car washes often have problems such as long waiting times, low car wash efficiency, and restrictions on business hours. Although self-service car washes have increased flexibility to a certain extent, they are still not convenient and automated enough. In cities, suitable car wash sites are often limited and the rent is high. Telescopic smart car wash equipment can be retracted when not in use, reducing the floor space and facilitating installation and layout in relatively small sites, such as some gas stations and idle corners in communities, increasing the range of locations where the equipment can be deployed. Summary of the invention

[0005] A telescopic intelligent car washing device comprises, from front to back, a head frame, a plurality of sequentially arranged middle frames and a tail frame; The head frame and the first intermediate frame, the two adjacent intermediate frames, and the last intermediate frame and the tail frame are connected in sequence by sliders and connectors; the sliders and connectors are located at the top of the device; Both sides of the head frame, the middle frame and the tail frame are provided with transverse rails, and the mechanical arms are slidably connected to the transverse rails; The ends of the transverse tracks on the head frame and the middle frame are connected to the longitudinal tracks; the adjacent frames are movably connected through the link track, the front end of the link track is slidably connected to the longitudinal track of the previous frame, and the end is rotatably connected to the front end of the transverse track of the next frame, that is: The longitudinal rail of the head frame is connected to the front end of the transverse rail on the first intermediate frame through the link rail; Between two adjacent intermediate frames: the longitudinal track of the first intermediate frame is connected to the front end of the transverse track of the second intermediate frame through the link track; The longitudinal rail of the last middle frame is connected to the front end of the transverse rail on the tail frame through the link rail.

[0006] The head frame and the first intermediate frame, two adjacent intermediate frames, and the last intermediate frame and the tail frame are all movably connected via a linking track and at least one movable nozzle.

[0007] The movable nozzle is provided with a plurality of nozzles; the inner side walls of the middle frame and the tail frame are provided with a plurality of nozzles one; the tops of the middle frame and the tail frame are provided with a plurality of nozzles two; the bottoms of the slider and the connecting piece are provided with a plurality of nozzles three; the height of the nozzle two is slightly lower than the height of the nozzle three.

[0008] The bottom of the head frame is provided with a crossbeam, and the side of the crossbeam is provided with a nozzle rack, and the nozzle rack is connected to the telescopic nozzle; the number of the nozzle rack and the telescopic nozzle is ≥ 2. The nozzle rack mainly supports the telescopic nozzle. When washing the car, the telescopic nozzle can be freely extended to the chassis part of the car for spraying and cleaning. After the work is completed, the telescopic nozzle retracts back to the nozzle rack, thereby saving space.

[0009] A support rod is arranged above the cross beam, the left and right ends of the support rod are connected to the left and right sides of the head frame, and the clamping plate is installed on the support rod.

[0010] A spray pipeline is installed above the support rod, and the left and right ends of the spray pipeline are respectively connected to the left and right sides of the head frame.

[0011] The left and right sides of the middle frame and the tail frame are also provided with a transverse track 1 parallel to the transverse track, all the transverse tracks have the same height, and all the transverse tracks 1 have the same height; the end of the transverse track 1 on the middle frame is connected to the longitudinal track 1; The two adjacent middle frames and the last middle frame are also connected to the tail frame through a link track 1, the front end of which is slidably connected to the longitudinal track 1 of the previous frame, and the end of which is rotatably connected to the front end of the transverse track 1 of the next frame.

[0012] The transverse track and / or transverse track 1 are also slidably connected with an air drying box; the top and both sides of the air drying box are provided with air blowing ports.

[0013] In the initial state, the robotic arms are located on the left and right sides of the inner side of the front frame, and the air drying box is located on the inner side of the rear frame.

[0014] The slider is slidably connected to the head frame or the middle frame, the connector is slidably connected to the slider, and the connector is fixedly connected to the middle frame or the tail frame.

[0015] The present invention also provides a car washing method based on the above device, comprising the following steps: S1.

At this time, the movable nozzle also extends out with the deployment of the device. After the device is fully deployed, fix the tail frame to the site to ensure that there is no displacement and shaking during the operation; S2. Drive the car to be washed into the deployed device, ensuring that the car body is completely covered by the telescopic intelligent car washing device, and the telescopic nozzle extends from the nozzle holder to the bottom of the vehicle chassis and between the two wheel hubs; S3. Open the all-round spraying mechanism: the nozzle, nozzle 1, nozzle 2, nozzle 3 and the telescopic nozzle spray water to the vehicle for preliminary cleaning; the telescopic nozzle sprays water in all directions; S4. After the whole vehicle is sprayed and rinsed, switch to spraying cleaning foam: Nozzle 1, Nozzle 2 and Nozzle 3 spray cleaning foam to the vehicle to deeply clean the dirt on the vehicle surface that is difficult to handle; S5. The wipe-dry cleaning mechanism is activated: the left and right mechanical arms clamp the towel and move along the horizontal track where the transverse track is located to scrub the side and roof of the vehicle body back and forth; after the scrubbing is completed, the nozzles, nozzle 1, nozzle 2, nozzle 3 and telescopic nozzle spray water for cleaning again, and the mechanical arm clamps the towel and moves to the clamping plate to clean it through the clamping and left and right horizontal pulling of the mechanical arm. At the same time, the spray pipe on the top of the clamping plate sprays cleaning liquid and water to clean the towel, so that it can be used for the next cleaning; S6. After cleaning, the air drying mechanism is started, and the air drying machine moves forward along the horizontal track to air dry the entire vehicle; In addition, the frames can be selectively extended according to the length of the vehicle to be washed; for short vehicles, only part of the frames need to be extended, and for adjacent unextended frames, the transverse track of the previous frame is directly connected to the transverse track of the next frame, and the transverse track of the previous frame is directly connected to the transverse track of the next frame, for the movement of the robotic arm or the dryer.

[0016] The beneficial effects of the present invention are as follows: (1) Car washing efficiency Fast and efficient cleaning: It is equipped with multiple special cleaning mechanisms, such as the chassis telescopic cleaning mechanism that can quickly spray and clean the chassis, and the omnidirectional spray cleaning mechanism that can spray and clean the car body from multiple angles at the same time. The coordinated work of various mechanisms can complete the cleaning of the entire car in a shorter time. Compared with traditional manual car washing, it greatly shortens the car washing time and improves the car washing efficiency. It can meet the car washing needs of more car owners, especially those who are short on time.

[0017] Flexible adaptation to different vehicle models: The telescopic design feature allows each cleaning component to be adjusted accordingly according to the size and contour of different vehicle models. For example, the sliding nozzle of the chassis telescopic cleaning mechanism can be extended to the appropriate length as needed to clean the chassis of different vehicles, and the mechanical arm slide rail of the intelligent wipe-dry cleaning mechanism can also adapt to the wiping needs of the roof, body side and other parts of different vehicles, ensuring that vehicles of various sizes and shapes can be cleaned more comprehensively and carefully.

[0018] (2) Car wash quality All-round cleaning without dead angles: The all-round spray washing mechanism is matched with the folding body and other related parts. No matter the side, top, bottom or some corners of the car body, it can be fully sprayed and washed through the cooperation of various mechanisms, avoiding the omissions or inadequate cleaning that may exist in manual car washing, ensuring the overall cleaning of the vehicle and improving the quality and effect of car washing.

[0019] Stable cleaning process control: Relying on the intelligent control system, each cleaning link runs accurately according to the set program. The pressure, angle, duration of the water spray and the strength of wiping can all remain relatively stable, so that each car wash can achieve a relatively consistent high quality standard, reducing quality fluctuations caused by differences in manual operations.

[0020] (3) Space and site utilization Save site space: When not working, the foldable body can be retracted and folded, and the retractable parts of the chassis telescopic cleaning mechanism can also be retracted, greatly reducing the space occupied by the overall equipment. In this way, it can be installed in relatively small venues, such as some gas stations with limited space in the city, small open spaces in communities, etc., which greatly expands the range of places where the equipment can be deployed and improves the utilization rate of site resources.

[0021] Easy to adjust the site layout: Due to its scalability and relatively compact storage characteristics, when the site needs to be replanned or the equipment needs to be relocated, it can be moved and rearranged more conveniently, and the operating difficulty and cost are much lower than some fixed, large and non-scalable car washing equipment.

[0022] (4) Cost and operation Reduce labor costs: Smart car washing equipment has greatly reduced the dependence on manual labor. The entire car washing process is basically completed by automated cleaning, wiping, air drying and other mechanisms. There is no need to hire more car washing workers like traditional car washing. In the long run, it can significantly reduce labor cost expenditures during operations and improve economic benefits.

[0023] Reduce resource waste: The amount of water can be accurately controlled to avoid excessive waste of water resources. Some equipment also has water recycling function. The durability of the equipment itself combined with the telescopic design reduces unnecessary losses, etc., which reduces resource consumption and operating costs in many ways, and is also in line with the concept of environmental protection.
