A vehicle cleaning solution using a drone. It's about the supply system.

In general, a drone is an unmanned aerial vehicle (UAV) shaped like an airplane or helicopter that can fly and control without a pilot. An unmanned aerial vehicle refers to an aircraft that is controlled remotely from the ground without a pilot on board to perform a certain mission, or that flies on its own by recognizing and judging the surrounding environment using a pre-entered mission program.

Drones began to be used by the military in preparation for war for purposes such as surveillance, reconnaissance, and attack. Recently, as their scope of application has rapidly expanded to industrial and civilian use, civilian demand is expected to exceed military demand.

Drones, which have excellent sensing capabilities and rapid mobility, including cameras and sensors, are being recognized for their commercial potential as technology advances. Currently, the scope of use of drones is gradually expanding to private and public fields such as broadcasting filming, recreation, agriculture, communication relay, disaster information collection for polluted and natural disaster areas, and delivery logistics, and their application to these fields is increasing. It is being developed in various forms to make it possible. In addition, the civilian drone market is expected to become more active in the future as low-cost drones that are easy to operate and can be controlled with a smartphone using an app are being released.

As an example of the civilian drone market, agricultural drones are being developed to spray pesticides on large agricultural fields. In the case of these agricultural drones, drones suitable for each characteristic are being developed so that they can spray various types of pesticides or fertilizers, such as liquid and powder types.

When using agricultural drones, they can carry up to 10 kg and spray pesticides on an area of about 12,000 pyeong per hour, so they can replace dozens of workers, and are in great demand due to the advantages of greatly reducing costs and spraying pesticides safely. It is increasing, and market expansion and technological development are expected in the future.

Additionally, as another example of the civilian drone market, drones are being used for firefighting purposes as they can move quickly and accurately without being greatly affected by obstacles on the ground.

Drones used for firefighting purposes can secure golden time and minimize damage to property and people by allowing them to be used for fire suppression at an early stage.

Drones for firefighting purposes are equipped with fire extinguishers and are used to extinguish fires by injecting fire extinguishers into the fire scene. They are mounted on fire trucks when a fire truck is dispatched, and operate the drone in places where it is difficult for fire trucks to enter, making a great contribution to initial fire suppression. It affects.

Alternatively, in the event of an emergency patient as well as fire suppression, drones can be deployed preemptively in an environment that is difficult for rescuers to access and quickly deliver emergency equipment or emergency supplies to the emergency site to deliver relief supplies necessary for emergency treatment of the patient. It can contribute to prolonging the patient’s life.

In addition, drones are being used for logistics delivery services by taking advantage of their flight capabilities and economic feasibility. After loading logistics onto a drone, you can input the coordinates into the drone and automatically perform the entire process of takeoff, flight, delivery, and return of the logistics you want to deliver, thereby reducing the cost and time required for logistics delivery.

However, despite the endless utility of these drones, there has been no development of drones for washing vehicles. In the case of a typical sedan, the ceiling of the vehicle is lower than a person's height, so the entire surface of the vehicle can be thoroughly washed using only a few car washing tools.

However, in the case of SUVs, RVs, and cargo trucks other than sedans, there are areas that cannot be reached by human hands, and there is a disadvantage that car washing is insufficient in those areas.

Therefore, there is a need to use the high accessibility of drones to wash cars in areas that cannot be reached by humans, and further develop a drone that automatically washes cars by setting a flight path and automatically spraying washing solution.

When the angle control gear 422 rotates, the angle of the spray body 500 changes along the rotation rack 520 whose length is formed in an arc shape. The angle of the spray nozzle 510 is adjusted so that it faces directly downward, horizontally, or slightly inclined downward.

A body neck 530, which is a groove to prevent the body from being separated from the gripper 420, is formed near the rotary rack 520. The body neck 530 is formed in an arc shape in the same manner as the arc-shaped rotating rack 520. The lower end of the grip part 420 is inserted into the body neck 530, and the locking structure prevents it from being separated from the grip part 420.

Looking at the operation of the spraying body 500 controlled by the posture adjusting unit 400, the initial state is set to a downward posture with the spraying nozzle 510 as shown in FIG. 7(a). In this position, the spray nozzle 510 sprays the cleaning solution downward.

When it is necessary to spray the cleaning solution on the side of the vehicle, the angle adjustment gear 422 is rotated to rotate the angle of the spray body 500, so that the spray nozzle 510 is tilted downward as shown in FIG. 7(b). , or form an attitude so that the cleaning solution can be sprayed horizontally as shown in Figure 7(c).

In addition, in order to improve cleaning efficiency by bringing the injection nozzle 510 closer to the side of the vehicle, the posture adjusting unit 400 is rotated by rotating the moving gear 411 as shown in Figure 7(b) and Figure 7(c). By moving from the center of the main body 200 to one side, the injection nozzle 510 can be brought closer to the vehicle. In this case, the propeller 120, which is arranged in a horizontal direction and rotates, can protect against damage such as scratches and scratches when approaching the exterior of the vehicle, and the spray nozzle 510 is placed as close to the vehicle as possible to spray strong spray. You can wash your car with pressure.

In addition, when the drone of the present invention takes off, the electric cylinder 413 is extended as shown in FIG. 6(b) so that the spray nozzle 510 protrudes further downward than the bottom of the washing container 300. When the cleaning solution is sprayed from the spray nozzle 510, it is not blocked by the cleaning container 300 and can be smoothly sprayed onto the vehicle.

When the drone of the present invention lands, the electric cylinder 413 is contracted again as shown in FIG. 6(a) so that the spray nozzle 510 is positioned more upward than the bottom of the washing container 300. The landing pad 310 of the washing container 300 is allowed to contact the ground.

As shown in Figure 5(b), the spray body 500 is equipped with a suction pump 550 that suctions and pressurizes the cleaning solution contained in the cleaning container 300 so that it can be strongly sprayed from the spray nozzle 510. do.

The suction pump 550 is coupled to a plurality of hoses 330 extending from the washing containers 300, and has a solenoid valve (not shown) built in to selectively open or close the plurality of hoses 330. do. Therefore, the cleaning solution is selectively sucked and sent to the spray nozzle 510.

The recognizer 540 may be composed of a number of components such as a camera, radar, lidar, and ultrasonic sensor in a complex manner.

The recognizer 540 acquires vehicle information, extracts 3D image data of the vehicle, and also recognizes contaminated areas on the exterior of the vehicle.

The method of acquiring 3D image data of a vehicle from the recognizer 540 may be a method of extracting information captured through multi-angle shooting itself from the control unit 220, or a part or all of the license plate or exterior of the vehicle. is photographed and transmitted to the central server through the communication unit 230, the central server determines the vehicle type based on this, and transmits the 3D image data of the vehicle stored in the big data to the communication unit 230, and the control unit 220 This may be a way to obtain it.

The recognizer 540 performs a process of comparing with 3D image data acquired while scanning the exterior of the vehicle, and determines the presence or absence of contaminants, allowing more intensive cleaning of areas with contaminants during future car washing processes.

When extracting 3D image data from the control unit 220, the exterior of the vehicle, such as the shape and license plate, is photographed through the recognizer 540, the vehicle information is transmitted to the control unit 220, and the learned information and preset data are collected. Based on this, 3D image data can be extracted by analyzing the captured vehicle information with an artificial intelligence system.

In addition, the 3D image data obtained from the control unit 220 and the exterior of the vehicle captured by the recognizer 540 are compared and analyzed by an artificial intelligence system to comprehensively determine the type and size of contaminants, the amount of cleaning solution required, etc. You can make your own decisions based on this consideration, and you can accurately and effectively wash your car based on this information while flying along the flight path.

After acquiring 3D image data of the vehicle to be washed through the recognizer 540, the control unit 220 sets the flight path of the drone of the present invention based on this data.

Since the car wash is carried out using a drone, it is necessary to be able to spray the washing solution over the entire area without missing any parts, and the flight path is set to maintain the spray angle at a right angle according to the curves of the vehicle.

The flight path includes a first path for spraying the cleaning solution on the upper surface of the vehicle, as shown in FIG. 7(a). The first path travels between the front and rear sides of the vehicle and sprays the cleaning solution on the upper surface. At this time, the direction of the spray nozzle 510 is directed downward, and the electric cylinder 413 is extended to spray the spray. The nozzle 510 protrudes further downward than the bottom of the cleaning container 300, so that the sprayed cleaning solution is not obstructed by the cleaning container 300.

The portion of the vehicle corresponding to the first path forms a horizontal surface on average, except for slight curves. Based on the sedan, this is the bonnet, ceiling, and trunk. Since the spray nozzle 510 sprays the cleaning solution at this area while maintaining a right-angled spray angle, it becomes easy to remove contaminants and the cleaning solution can be evenly distributed over a large area.

Additionally, the flight path includes a second path that moves forward and backward along the side window of the vehicle to be washed, as shown in FIG. 7(b). The second path may include the front and rear glass as well as the side glass.

The part of the vehicle corresponding to the second path has an incline that is neither horizontal nor vertical, but somewhere in between. Therefore, in accordance with the inclination and curvature of the vehicle, the drone of the present invention moves the moving gear 411 to rotate and the elevating part 410 moves to one side of the moving guide 240 to approach the side of the vehicle. The control gear 422 rotates so that the spray nozzle 510 is formed at a similar spray angle in response to the curvature and inclination of the vehicle. In this state, the cleaning solution is sprayed while flying the second route.

The flight path includes a third path that moves forward and backward along the fender and door of the vehicle, as shown in FIG. 7(c). The part of the vehicle corresponding to the third path forms a vertical surface on average, and the drone of the present invention operates so that the spray nozzle 510 is arranged in the horizontal direction corresponding to the vertical surface of the vehicle.

First, the moving gear 411 rotates so that the elevating part 410 moves to one side of the moving guide 240, and each control gear 422 rotates so that the spray nozzle 510 is placed in the horizontal direction. do. At this time, the spray nozzle 510 protrudes further than one side of the cleaning container 300, so that the sprayed cleaning solution is not obscured or obstructed by the cleaning container 300.

While flying along the third path, the drone can spray the cleaning solution at a spray angle perpendicular to the vertical surface of the vehicle, so the cleaning solution can be evenly distributed and contaminants can be detached with strong spray pressure.

The first, second, and third paths may be performed in any order, but for car washing efficiency, it is preferable to proceed from the top to the bottom of the vehicle.

An embodiment of car washing using a vehicle washing solution supply system using a drone of the present invention will be described. However, this explains the car washing process according to one embodiment, and the drone of the present invention can be applied in various ways to wash the car depending on the user.

The washing container 300 contains washing water used for prewashing, car shampoo for removing contaminants, polishing agent for polishing the exterior, and rinsing water for rinsing the washing solution.

First, the drone of the present invention takes off and scans the vehicle to be washed through the recognition device 540. Based on the vehicle information identified by the recognizer 540, 3D image data can be extracted from the control unit 220 or image data can be obtained from the central server.

Based on this image data, the control unit 220 sets a flight path including the first path, second path, and third path.

Afterwards, the drone flies along the set flight path and sprays washing water onto the vehicle to perform prewash. At this time, the position and posture of the injection nozzle 510 are changed through control operations corresponding to the first path, second path, and third path. At this time, as the washing water is sprayed, the load on the washing container 300 that accommodates the washing water gradually becomes lighter, and the load meter 320 measures this in real time, and the control unit 220 recognizes this and controls the thrust of the propeller 120 to ensure flight. Increases stability.

After the prewash process, car shampoo, rinse water, polish, and rinse water are sprayed onto the vehicle in that order along the set flight path.

While the car is being washed according to the car washing process input to the control unit 220, if a person or an external object approaches the drone, the car washing process can be stopped to prevent a safety accident, and an emergency landing can be controlled. there is.

Alternatively, users can directly control the drone and prevent safety accidents by switching to manual operation using the drone controller.

The vehicle washing solution supply system using a drone according to the present invention has a convenient advantage because it recognizes the shape of the vehicle and automatically washes the car while the drone flies along the flight path through a pre-entered car washing process.

In addition, the cleaning container 300 accommodates the cleaning solution required for car washing and at the same time functions as a bridge for landing, making the drone lighter and improving flight performance.

In addition, car washing efficiency is improved because the spray nozzle 510 is arranged in an efficient position and posture for washing according to the shape and curve of the vehicle.
