Description

Technical Field

[0001] This invention relates to the field of intelligent car washing, specifically to a telescopic intelligent car washing device and method. Background Technology

[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 suffer from long waiting times, low efficiency, and restrictions on operating hours. While self-service car washes offer some flexibility, they are still not convenient or automated enough. In cities, suitable car wash locations are often limited and expensive. Retractable smart car wash equipment can be retracted when not in use, reducing its footprint and facilitating installation in relatively small spaces, such as gas stations or unused corners in residential areas, thus increasing the range of locations where the equipment can be deployed. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a telescopic intelligent car wash device, comprising a chassis telescopic cleaning mechanism, a drying cleaning mechanism, a folding body mechanism, an all-around spraying mechanism, and a drying mechanism.

[0004] The chassis telescopic cleaning mechanism includes a head frame, a nozzle holder, a telescopic nozzle, and a crossbeam;

[0005] The drying and cleaning mechanism includes a support rod, a clamping plate, a robotic arm, a transverse track, and a spray pipe.

[0006] The folding fuselage mechanism includes a middle frame, connectors, sliders, connecting rails, movable nozzles, and longitudinal rails;

[0007] The all-around spraying mechanism includes a nozzle, nozzle one, nozzle two, and nozzle three;

[0008] The drying mechanism includes a tail frame, a drying box, and an air outlet.

[0009] A telescopic intelligent car wash device includes, from front to back, a head frame, multiple intermediate frames arranged in sequence, and a tail frame.

[0010] The head frame is connected to the first intermediate frame, to two adjacent intermediate frames, and to the tail frame in sequence by sliders and connectors; the sliders and connectors are located at the top of the device.

[0011] The head frame, middle frame and tail frame are all provided with transverse tracks on both sides of the interior, and a robotic arm is slidably connected on the transverse tracks.

[0012] The ends of the transverse tracks on the head frame and the middle frame are all connected to the longitudinal tracks; adjacent frames are movably connected by connecting tracks, the front end of which slides to connect to the longitudinal track of the preceding frame, and the end of which rotatably connects to the front end of the transverse track of the following frame, that is:

[0013] The longitudinal rails of the head frame are connected to the front end of the transverse rails on the first intermediate frame via connecting rails;

[0014] Between two adjacent intermediate frames: the longitudinal track of the previous intermediate frame is connected to the front end of the transverse track of the next intermediate frame via a connecting track;

[0015] The longitudinal track of the last intermediate frame is connected to the front end of the transverse track on the tail frame via a link track.

[0016] The head frame is connected to the first intermediate frame, to two adjacent intermediate frames, and to the last intermediate frame and the tail frame via a link rail and at least one movable nozzle.

[0017] The movable nozzle is provided with several nozzles; several nozzles one are provided on the inner sidewalls of the middle frame and the tail frame; several nozzles two are provided on the top of the middle frame and the tail frame; several nozzles three are provided on the bottom of the slider and the connector; the height of nozzle two is slightly lower than the height of nozzle three.

[0018] The head frame has a crossbeam at its bottom, and a nozzle holder is located on the side of the crossbeam. The nozzle holder connects to the telescopic nozzle; the number of nozzle holders and telescopic nozzles is ≥2. The nozzle holder mainly supports the telescopic nozzle. During car washing, the telescopic nozzle can freely extend and retract to the chassis for spraying and cleaning. After the work is completed, the telescopic nozzle retracts back into the nozzle holder, thus saving space.

[0019] A support rod is provided above the crossbeam, and the left and right ends of the support rod are connected to the left and right sides of the head frame. The clamping plate is installed on the support rod.

[0020] A spray pipe is installed above the support rod, and the left and right ends of the spray pipe are respectively connected to the left and right sides of the head frame.

[0021] The middle frame and the tail frame are also provided with transverse rails on the left and right sides, which are parallel to the transverse rails. All transverse rails are at the same height. The ends of the transverse rails on the middle frame are connected to the longitudinal rails.

[0022] The two adjacent intermediate frames and the last intermediate frame are also connected by a connecting track 1. The front end of the connecting track 1 is slidably connected to the longitudinal track 1 of the previous frame, and the end is rotatably connected to the front end of the transverse track 1 of the next frame.

[0023] A drying box is slidably connected to the transverse track and / or transverse track one; the top and sides of the drying box are provided with air outlets.

[0024] In the initial state, the robotic arm is located on the left and right sides inside the front frame, and the drying box is located inside the tail frame.

[0025] 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.

[0026] The present invention also provides a car washing method based on the above-mentioned device, comprising the following steps:

[0027] S1. Fix the head frame, and slide the slider and connector out of the frame; at the same time, the front end of the connecting track slides along the longitudinal track, the front end of the first connecting track slides along the longitudinal track, the end of the connecting track rotates around the transverse track, and the end of the first connecting track rotates around the transverse track. The connecting track and the transverse track are connected to form a horizontal track, and the first connecting track and the transverse track are connected to form a horizontal track. At this time, the movable nozzle also extends out as the device is deployed. After the device is fully deployed, fix the tail frame to the site to ensure that there is no displacement or shaking during operation.

[0028] S2. Drive the car to be washed into the unfolded device, ensuring that the car body is completely covered by the telescopic intelligent car wash device. The telescopic nozzles extend from the nozzle frame and extend under the vehicle chassis and between the two wheel hubs.

[0029] S3. Activate the all-around spray washing mechanism: Nozzles, Nozzle 1, Nozzle 2, Nozzle 3, and telescopic nozzles spray clean water onto the vehicle for initial cleaning; the telescopic nozzles spray water in all directions.

[0030] S4. After the full vehicle spray wash, switch to spraying cleaning foam: spray cleaning foam onto the vehicle through nozzles 1, 2 and 3 to deeply clean the dirt that is difficult to remove from the vehicle surface;

[0031] S5. The drying and cleaning mechanism is activated: The two robotic arms on the left and right clamp the towel and move along the horizontal track to wipe the sides and roof of the vehicle body back and forth. After wiping, the nozzles, nozzle one, nozzle two, nozzle three and telescopic nozzle spray water to clean again. At this time, the robotic arms clamp the towel and move to the clamping plate. The clamping plate and the left and right horizontal pulling of the robotic arms are used to clean. At the same time, the spray pipes at the top of the clamping plate spray cleaning liquid and water to clean the towel, making it easy to use for the next cleaning.

[0032] S6. After cleaning, start the drying mechanism. The dryer moves forward along the horizontal track to dry the entire vehicle.

[0033] In addition, the frame can be selectively extended according to the length of the vehicle to be washed; for short vehicles, only part of the frame needs 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 dryer.

[0034] The beneficial effects of this invention are as follows:

[0035] (1) Car wash efficiency

[0036] Fast and efficient cleaning: It has multiple specialized cleaning mechanisms, such as a chassis telescopic cleaning mechanism that can quickly spray and clean the car chassis, and an all-round spraying mechanism that can spray and wash the car body from multiple angles at the same time. The coordinated work of these mechanisms can complete the cleaning of the entire car in a short time. Compared with traditional manual car washing, it greatly shortens the car washing time and improves car washing efficiency, which can meet the car washing needs of more car owners, especially those car owners who are short on time.

[0037] Flexible adaptation to different vehicle models: The telescopic design allows each cleaning component to be adjusted to fit the size and shape of different vehicle models. For example, the sliding nozzles of the chassis telescopic cleaning mechanism can extend to the appropriate length to clean the chassis of different vehicles as needed, while the robotic arm rails of the intelligent drying cleaning mechanism can also be adapted to the wiping needs of different vehicles' roofs, sides, and other parts, ensuring a comprehensive and meticulous cleaning for vehicles of all sizes and shapes.

[0038] (2) Car wash quality

[0039] All-around cleaning without blind spots: The all-around spray washing mechanism, combined with the folding body and other related components, can thoroughly clean the sides, top, bottom, and corners of the vehicle through the cooperation of various mechanisms. This avoids the omissions or inadequate cleaning that may occur with manual car washing, ensuring that the vehicle is clean overall and improving the quality and effect of car washing.

[0040] Stable cleaning process control: Relying on the intelligent control system, each cleaning step runs precisely according to the set program. The water spray pressure, angle, duration, and drying force can all remain relatively stable, so that each car wash can achieve a relatively consistent high-quality standard and reduce quality fluctuations caused by differences in human operation.

[0041] (3) Space and site utilization

[0042] Space saving: When not in use, the folding 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. As a result, it can be installed in relatively small spaces, such as some gas stations with limited space in the city, small open spaces in residential areas, etc., which greatly expands the range of places where the equipment can be deployed and improves the utilization rate of site resources.

[0043] Easy to adjust site layout: Due to its scalability and relatively compact storage features, it can be moved and rearranged more easily when the site needs to be replanned or the equipment needs to be relocated. The operation difficulty and cost are much lower than some fixed, large and non-scalable car wash equipment.

[0044] (4) Cost and Operation

[0045] Reduced labor costs: Intelligent car wash equipment greatly reduces reliance on manual labor. The entire car wash process is basically completed by automated cleaning, drying, and air drying mechanisms, eliminating the need to hire a large number of car wash workers as in traditional car washes. In the long run, this can significantly reduce labor costs during operation and improve economic efficiency.

[0046] Reduce resource waste: Water volume can be precisely controlled to avoid excessive waste of water resources. Some equipment also has water recycling function. In addition, the durability of the equipment itself, combined with the telescopic design to reduce unnecessary wear and tear, reduces resource consumption and operating costs from multiple aspects, while also conforming to the concept of environmental protection.
