Description

Technical Field

[0001] The present invention relates to the technical field of vehicle cleaning equipment, and in particular to a vehicle cleaning device. Background Art

[0002] With the development of society, cars have become increasingly popular as a daily means of transportation. After a car has been parked or driven for a long time, dust will adhere to the outer wall of the car, affecting the appearance of the car. In addition, when bird droppings or leaves rot and decompose on the car, they will also corrode the car paint. In severe cases, it will also cause metal corrosion of the car body, affecting the strength of the car body. Therefore, the vehicle needs to be cleaned and maintained regularly.

[0003] The current conventional vehicle cleaning and maintenance measures are manual cleaning or cleaning with car washing equipment. However, the current car washing equipment is basically a fixed structure when used, and the vehicle driver needs to adjust the position and angle of the vehicle before cleaning the vehicle. If the driver is not skilled, it will take a long time to adjust the position and angle of the vehicle, affecting the driver's vehicle cleaning experience.

[0004] Furthermore, the current vehicle cleaning device basically adopts a gantry crane structure with synchronous movement at both ends. When cleaning the surfaces of both sides of the vehicle, if the surface of one side of the vehicle is clean and the surface of the other side has more attachments, the gantry crane will move synchronously at both ends to clean the vehicle. In this case, the device will still repeatedly clean the clean surface of the vehicle, resulting in a waste of resources and an increase in the cost of using the device.

[0005] In view of the problems exposed in the current vehicle cleaning process, it is necessary to improve and optimize the vehicle cleaning equipment. Summary of the Invention

[0013] As a preferred technical solution of the vehicle washing device of the present invention, the driven plate is rotatably connected to the first base plate via a rotating shaft, and the driven plate is driven to deflect at an angle on the side wall of the first base plate via an angle adjustment component.

[0014] As a preferred technical solution of a vehicle washing device of the present invention, the traction assembly includes a traction motor arranged on the inner wall of the driven plate, the output shaft of the traction motor is connected to the traction rope and drags the traction rope;

[0015] The flexible robotic arm is an articulated structure in which multiple rotating joint deflection blocks are connected to the rotating shaft in sequence. The support assembly includes several spring support blocks fixedly arranged inside the deflection block. Several spring support blocks are fixed inside the deflection block. A buffer spring is fixed on each spring support block. A limit block is also fixed at the top of the buffer spring.

[0020] Compared with the prior art, the present invention has the following beneficial effects.

[0021] 1. The vehicle cleaning device is equipped with a movable body. The angle and position of the body can be adjusted through the universal wheels at the bottom. The position can be adjusted when the vehicle is stationary, so that the cleaning device can be coordinated with the vehicle. The driver does not need to manually and accurately position the vehicle to clean the vehicle, which effectively improves the user experience of the vehicle driver.

[0022] 2. Spacing adjustment components are added on both sides of the mobile body. When the spacing adjustment components are in operation, the spacing adjustment motor drives the rack to move, thereby changing the spacing between the connecting plate and the mobile body. When the spacing between the two connecting plates changes, the spacing between the two scissor arms can be adjusted synchronously, thereby changing the spacing between the flexible robotic arms, making it easier for the vehicle cleaning device to clean vehicles of different widths.

[0023] 3. A scissor arm is added to the cleaning device. When the scissor arm is extended, the flexible robotic arm is pushed out from the inner side of the connecting plate, and when the scissor arm is retracted, the flexible robotic arm is retracted to the inner side of the connecting plate, thereby reducing the size of the device, making it easier for the cleaning equipment to enter the vehicle parking area without interfering with the surrounding vehicle facilities, and avoiding collisions between the driver and the cleaning device during parking when the driver is unskilled.

[0024] 4. The cleaning device is equipped with an angle deflection motor. When the angle deflection motor is running, the driven plate is deflected on the side wall of the first substrate. The flexible robotic arm can clean the front and rear of the vehicle when it deflects clockwise or counterclockwise. The two flexible robotic arms can operate independently and clean the outer wall of the vehicle on both sides of the vehicle, thereby improving the cleaning efficiency and reducing the waste of water and electricity resources.

[0025] 5. A traction motor is added to the inner side of the driven plate. When the traction motor is running, it pulls the traction rope, causing the flexible robotic arm to deflect toward one side of the vehicle body, making it easier for the nozzle to spray water on the vehicle body for cleaning. When the flexible robotic arm deflects, the brush bristles can fit into the outer wall of the vehicle body. When the flexible robotic arm deflects with the angle deflection motor as the axis, the brush bristles can scrape and clean the head, top and tail of the vehicle body. When the scissor arm is extended or retracted, the position of the flexible robotic arm is adjusted on the horizontal plane, making it easier to clean various parts of the vehicle body through the nozzle and the brush bristles.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example

[0038] like Figures 1-8 As shown, a vehicle cleaning device disclosed in the present invention includes a mobile body 1, and connecting plates 3 are symmetrically provided on both sides of one end of the mobile body 1. The spacing of the two connecting plates 3 is adjusted by a spacing adjustment component. Each of the connecting plates 3 is connected to a lateral displacement component, and the other ends of the two lateral displacement components are connected to a first base plate 6, and the opposite side walls of the two first base plates 6 are connected to a deflectable driven plate 8 through a rotating shaft.

[0039] The connecting plate 3 disclosed in this embodiment is an L-shaped sheet structure. When the scissor arm 4 is retracted, the driven plate 8 can be stored on the inner side of the connecting plate 3, thereby reducing the occupied volume of the entire cleaning equipment. In this embodiment, the two driven plates 8 can have their own independent movement states, which is convenient for cleaning the vehicle according to the on-site conditions.

[0040] Flexible robotic arms 9 are connected to the upper surfaces of both ends of the driven plate 8, and several partitions 17 are evenly connected and arranged between the two flexible robotic arms 9. The function of the partition 17 is to serve as a structural support between the two flexible robotic arms 9, so that the structure in the device remains stable, and it is convenient to fix the elastic component to adjust the rebound structural force. Then the water pipe 11 and the brush assembly 12 are installed through a U-shaped block or a C-shaped block. The U-shaped block or the C-shaped block is stuck on the outer wall of the water pipe 11 or the brush assembly 12, and the free end of the U-shaped block or the C-shaped block is stuck on the partition 17, so that the water pipe 11 and the brush assembly 12 remain stable.

[0041] Flexible robotic arms 9 are connected to the upper surfaces of both ends of the driven plate 8. The flexible robotic arms 9 can be bent by a traction component or bent and straightened by a driving component. The traction component includes a traction rope 26, and the traction rope 26 is connected to the flexible robotic arm 9 through a support component. When a driving motor is installed on the rotating shaft of the flexible robotic arm 9, the flexible robotic arm 9 can be driven to rotate by the driving motor, so that the flexible arm can be bent or straightened. The above-mentioned embodiment is only any one of the technical solutions disclosed in this technical solution. The bending method of the flexible robotic arm 9 in this technical solution is not limited to the above-mentioned traction component or driving component, and it is only necessary to achieve the bending of the flexible robotic arm 9.

[0042] When the traction rope 26 used in this embodiment is tightened, the flexible robotic arm 9 can be pulled to swing, so that the flexible robotic arm 9 is tilted toward the side of the car to be cleaned, which facilitates the adjustment of the orientation of the water pipe 11 and the brush assembly 12, so that the water pipe 11 and the brush assembly 12 can clean the car.

[0043] A water pipe 11 is vertically connected to the inner side of the two flexible robotic arms 9. The water pipe 11 is connected to the cleaning liquid tank in the mobile body 1 through an infusion pipe. A number of nozzles 13 are evenly arranged on the surface of one side of the water pipe 11. Brush assemblies 12 are symmetrically and vertically provided on both sides of the water pipe 11 in the flexible robotic arm 9. Brush bristles 14 are evenly arranged on the surface of one side of the brush assembly 12. The water pipe 11 and brush assembly 12 used in this embodiment are both flexible structures, which can follow the synchronous deflection of the flexible robotic arm 9.

[0044] Specifically, the spacing adjustment component includes a guide rail 19 and a spacing adjustment motor 20. The guide rail 19 is horizontally fixed on the side wall of the mobile body 1, and one end of the connecting plate 3 extends toward the mobile body 1 to form an extended end, and a slider engaged with the guide rail 19 is fixed on the side wall of the extended end. The side wall of the mobile body 1 is horizontally connected with a rack 18, and the side wall of the extended end is installed with a spacing adjustment motor 20. A transmission gear is sleeved on the output shaft of the spacing adjustment motor 20, and the transmission gear is meshed with the teeth of the rack 18. In this embodiment, when the spacing adjustment motor 20 is running, the transmission gear and the rack 18 are relatively displaced, so that the spacing adjustment motor 20 drives the connecting plate 3 to displace, so that the two connecting plates 3 are closer or farther away.

[0045] Specifically, the lateral displacement assembly includes a retractable scissor arm 4, and both ends of each of the scissor arms 4 are respectively connected to the connecting plate 3 and the first base plate 6 through a connecting assembly. One of the implementation methods disclosed in this embodiment uses a scissor arm 4, and other components that can be retracted in the horizontal direction may also be used, such as a telescopic rod that can be pushed out horizontally.

[0046] Specifically, the connecting assembly includes a first slide rail 2 and a second slide rail 5. The first slide rail 2 is vertically arranged on the side wall of the connecting plate 3, and the second slide rail 5 is vertically arranged on the side wall of the first base plate 6. A bidirectional lead screw that can rotate around its axis is vertically arranged in the second slide rail 5 and the first slide rail 2. Both ends of the scissor arm 4 are sleeved on the bidirectional lead screw. A servo motor is provided at the top of the first slide rail 2 and the second slide rail 5. The output shaft of the servo motor drives the bidirectional lead screw to rotate and makes the total length of the scissor arm 4 extend or shorten. In this embodiment, both ends of the scissor arm 4 are connected to a sliding block through a rotating shaft, and the sliding block is threadedly matched with the bidirectional lead screw to adjust the total length of the scissor arm 4 itself.

[0047] Specifically, the driven plate 8 is rotatably connected to the first substrate 6 through a rotating shaft, and the driven plate 8 is driven by the angle adjustment component to deflect the side wall of the first substrate 6. The angle adjustment component in this embodiment adopts an angle deflection motor 15, and the inner wall of the driven plate 8 is fixed with an angle deflection motor 15. The output shaft of the angle deflection motor 15 passes through the driven plate 8 and is connected to the first substrate 6. The angle deflection motor 15 drives the driven plate 8 to deflect the side wall of the first substrate 6. In this embodiment, two angle deflection motors 15 are used, so that the two driven plates 8 can have independent movement modes, which is convenient for cleaning the surfaces on both sides of the vehicle to different degrees.

[0048] Specifically, the traction assembly includes a traction motor 16 disposed on the inner wall of the driven plate 8 , and the output shaft of the traction motor 16 is connected to the traction rope 26 and drags the traction rope 26 .

[0049] The flexible robotic arm 9 is an articulated structure in which multiple rotating joint deflection blocks and rotating shafts are connected in sequence. The support assembly includes several spring support blocks 27 fixedly arranged inside the deflection block. Several spring support blocks 27 are fixed inside the deflection block. A buffer spring 23 is fixed on each spring support block 27. A limit block 24 is also fixed at the top of the buffer spring 23. The traction rope 26 passes through the buffer spring 23 and the spring support block 27, and the traction rope 26 is fixedly connected to the limit block 24. In this embodiment, the staff can adjust the number of spring support blocks 27 used according to their own needs. By hooking the traction rope 26 with different numbers of spring support blocks 27, the flexible robotic arm 9 can have different deflection amounts of the arc, and at the same time avoid the traction rope 26 from being exposed from the inner side of the flexible robotic arm 9 when the flexible robotic arm 9 is bent and the traction rope 26 is tightened, effectively avoiding contact between the traction rope 26 and the vehicle.

[0050] Specifically, the flexible robotic arm 9 includes a partition 17, and several partitions 17 are evenly arranged on the inner side of the flexible robotic arm 9. Several elastic components 10 are fitted on the outer side of the partition 17. The elastic components 10 are connected to the partition 17 through a limiting assembly. When the traction rope 26 is not tightened, the elastic component 10 straightens the flexible robotic arm 9 through its own elastic force.

[0051] Specifically, the limiting assembly includes a card block 22, and several groups of card blocks 22 are evenly arranged on the outer walls of the two flexible robotic arms 9, and two card blocks 22 at the same height extend close to each other at the end away from the flexible robotic arm 9, and limit the elastic member 10. In this embodiment, a lifting block is also protruding from the outer wall of the driven plate 8, which can lift the bottom end of the elastic member 10, so that the bottom end of the elastic member 10 remains stable, making it easier for the elastic member 10 and the flexible robotic arm 9 to complete the deflection action together.

[0052] Specifically, a limit plate 21 is provided on the side wall of the flexible robotic arm 9 facing the elastic component 10. The limit plate 21 is connected to the deflection block and limits the deflection block deflected toward the elastic component 10. In this embodiment, the limit plate 21 further increases the resistance of the flexible robotic arm 9 during reverse deflection, thereby preventing the flexible robotic arm 9 from deflecting toward the elastic component 10, thereby allowing the flexible robotic arm 9 to remain vertical when not being dragged by the traction rope 26. The elastic component 10 disclosed in this embodiment is a plate-shaped elastic member, which can be made of metal with a certain elasticity, or a retractable elastic structural member, or a spring with retractable elastic force, a gas spring, etc. It is only necessary to apply a force to the flexible robotic arm 9 to pull it when the traction rope 26 is not tightened, so that the flexible robotic arm 9 can be straightened.

[0053] Specifically, a number of universal wheels are evenly provided at the bottom end of the mobile body 1, and a driving roller 7 is fixedly provided at the bottom end of the first substrate 6. In this embodiment, the vehicle cleaning device can adjust its own angle and position through the universal wheels. When the scissor arm 4 is extended, the driving roller 7 makes it easier for the first substrate 6 to complete the displacement.

[0054] The working principle and usage process of the present invention: When the vehicle washing device of the present invention is in use, the driver first parks the vehicle in a suitable car washing area. The universal wheel arranged at the bottom of the mobile body 1 can adjust the angle of the mobile body 1 itself when it is running. The universal wheel can adjust the position of the mobile body 1 on the ground while rotating, so that the mobile body 1 is close to the vehicle, and the scissor arms 4 arranged on both sides of the mobile body 1 are on both sides of the vehicle, so that the second slide rail 5 can maintain a proper distance and parallel displacement with both sides of the vehicle body during the pushing process.

[0055] Afterwards, when the spacing adjustment motor 20 is powered on and running, it drives the gear on its own output shaft to rotate. When the gear rotates, it drives the rack 18 to move, and then the connecting plate 3 moves along the guide rail 19. The two connecting plates 3 can make relative displacement on both sides of the mobile body 1, and then adjust the spacing between the two first slide rails 2. When the spacing between the two first slide rails 2 is adjusted, the cleaning device can facilitate the cleaning of vehicles of different sizes.

[0056] The scissor arm 4 adjusts its own length when it is in operation. When the scissor arm 4 is in operation, its own length is extended, and then the driven plate 8 and the flexible robotic arm 9 are pushed out from the inner side of the connecting plate 3, so that the driven plate 8 and the flexible robotic arm 9 are displaced along the vehicle body, driving the roller 7 to roll on the ground and keep the driven plate 8 and the flexible robotic arm 9 stable.

[0057] When the driven plate 8 and the flexible mechanical arm 9 are displaced on the side of the vehicle body, the water pipe 11 supplies water through the pipeline, and the water in the water pipe 11 is sprayed out through the nozzle 13 to spray and clean the outer wall of the vehicle.

[0058] A brush assembly 12 is also embedded on the inner side of the flexible robotic arm 9 , and the bristles 14 in the brush assembly 12 can scrub the outer wall of the vehicle.

[0059] When the traction motor 16 set inside the driven plate 8 is running, it can drive its own output shaft to rotate, and then tighten the traction rope 26 wound on the output shaft of the traction motor 16. The traction rope 26 is tightened and tightened in this process. The traction rope 26 drives the limit block 24 to move downward together, and at the same time pressurizes the buffer spring 23. The spring support block 27 lifts the buffer spring 23 when the traction rope 26 is tightened and tightened. When the traction rope 26 is tightened and pulled, the bending curvature of the flexible mechanical arm 9 can be adjusted. The flexible mechanical arm 9 is pulled by the traction rope 26, so that the flexible mechanical arm 9 is pulled to tilt and bend toward one side of the vehicle.

[0060] When the flexible robotic arm 9 is bent by the traction rope 26, it can form a structure that matches the outer wall of the vehicle being cleaned, allowing the brush bristles 14 to contact the outer wall of the vehicle, thereby facilitating the brush bristles 14 to clean the outer wall of the vehicle.

[0061] The elastic component 10 is arranged on the side of the partition 17 away from the water pipe 11, and the elastic component 10 is attached to the outer wall of the flexible robotic arm 9, so that the traction rope 26 rebounds the flexible robotic arm 9 when it is released, so that the flexible robotic arm 9 remains in a vertical state after rebounding.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
