Description

Technical Field

[0001] This utility model relates to the field of vehicle cleaning technology, and in particular to a mobile vehicle cleaning device. Background Technology

[0002] Large vehicles include buses, long-distance and short-distance passenger vehicles, and freight vehicles. The traditional way to clean the exterior of these vehicles is by manually scrubbing with brushes or rinsing with high-pressure water guns. Compared to car washing, the fixed gantry washing machines used for large vehicles occupy a large area, are bulky, require a large investment, and have poor flexibility.

[0003] Mobile cleaning equipment, such as the patented mobile brush-type large operating vehicle cleaning machine with publication number CN2334643Y and the patented mobile train exterior washing and brushing device with publication number CN205113107U, can be moved to clean the sides of large vehicles. However, the cleaning brush of the existing mobile cleaning equipment is fixed relative to the vehicle body carrying the cleaning brush. During the movement of the vehicle body, the contact degree between the cleaning brush and the large vehicle can only be adjusted by changing the position of the vehicle body. If the distance is too close, it is easy to damage the large vehicle and the cleaning equipment. If the distance is too far, the cleaning effect is poor. And it is difficult to operate by adjusting the distance between the cleaning brush and the large vehicle by moving the vehicle body. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Specific embodiments of the mobile vehicle washing device provided by this utility model:

[0026] Please see Figures 1-7 A mobile vehicle washing device includes a mobile vehicle body 1; a front wheel 16 and a third motor 17 for driving the front wheel 16 are installed on the lower front side of the vehicle body 1. There is one front wheel 16. A gear reducer is provided between the third motor 17 and the front wheel 16. The third motor 17 drives the front wheel 16 to rotate as a power source so that the vehicle body 1 can move.

[0027] The front of the vehicle body 1 is equipped with a hood 19, and a headlight is located on the front side of the hood 19. A steering wheel 20 that drives the front wheels 16 is mounted on the upper front side of the vehicle body 1. A wheel frame for mounting the front wheels 16 is located on the lower front side of the vehicle body 1. The wheel frame is horizontally rotatable and mounted on the lower front side of the vehicle body 1. The steering wheel 20 is connected to the wheel frame via a drive shaft. Turning the steering wheel 20 can change the direction of the wheel frame and the front wheels 16, thereby achieving steering during the movement of the vehicle body 1. The hood 19 includes several front panels that conceal the drive shaft and enhance aesthetics.

[0028] Two rear wheels 18 are mounted on the lower rear side of the vehicle body 1. The two rear wheels 18 are symmetrically located on both sides of the rear of the vehicle body 1 and are connected to the two ends of the same axle. The axle is rotatably mounted on the lower side of the vehicle body 1. The rear wheels 18 act as driven wheels and support the movement of the vehicle body 1 under the drive and guidance of the front wheels 16.

[0029] A seat 21 is located on the upper side of the middle of the vehicle body 1. The seat 21 is positioned behind the steering wheel 20 and has a gap between it and the steering wheel 20. The driver sits on the seat 21 and operates the steering wheel 20 to control the movement of the vehicle body 1. A battery box is located under the seat 21, which contains a rechargeable battery to power the electrical components installed on the vehicle body 1.

[0030] A semi-cylindrical protective cover 2 that moves laterally is provided on one side of the rear of the vehicle body 1. A columnar roller brush 4 and a first motor 5 that drives the roller brush 4 to rotate are mounted on the protective cover 2. The roller brush 4 is installed vertically with its central axis set vertically. The opening of the protective cover 2 faces the outside of the vehicle body 1 and partially surrounds the roller brush 4. The first motor 5 is mounted on the upper side of the protective cover 2 and drives the roller brush 4 to rotate. A motor cover that protects the first motor 5 is provided on the upper side of the protective cover 2. The motor cover is connected to the protective cover 2 by bolts and has ventilation holes.

[0031] The outer side of the roller brush 4 is evenly covered with flexible bristles. When the roller brush 4 is stationary, the flexible bristles hang naturally. When the roller brush 4 rotates, under the action of centrifugal force, the flexible bristles spread out and come into contact with the side of the large vehicle, thus cleaning the surface of the large vehicle. The protective cover 2 maintains a distance from the large vehicle and avoids contact with it. The protective cover 2 shields the rotating roller brush 4, reducing the spread of dirt released by the roller brush 4 to the vehicle body 1 and its surroundings. The dirt is trapped inside the protective cover 2.

[0032] The protective cover 2 can move the roller brush 4 laterally, with the direction of movement perpendicular to the front-to-back direction of the vehicle body 1. That is, the direction of movement of the protective cover 2 and the roller brush 4 is perpendicular to the direction of travel of the rear wheels 18. The lateral movement of the protective cover 2 can adjust the distance between it and the large vehicle, thereby adjusting the contact area between the roller brush 4 and the large vehicle, adjusting the cleaning intensity, which is beneficial to improving cleaning efficiency and cleaning effect.

[0033] A bellows cover 3 connects the vehicle body 1 and the protective cover 2. The bellows cover 3 can cover the gap between the protective cover 2 and the vehicle body 1. During the lateral movement of the protective cover 2, the bellows cover 3 extends and retracts to cover the connection between the protective cover 2 and the vehicle body 1, ensuring aesthetics, protecting the internal structure, preventing external personnel from contacting the internal structure, and improving safety.

[0034] In this embodiment, a chassis 15 is provided on the upper rear side of the vehicle body 1, and a bellows cover 3 is connected between the protective cover 2 and the chassis 15. The chassis 15 corresponds to the lower middle part of the protective cover 2. Multiple bellows covers 3 are provided and distributed at the connection points between the chassis 15 and the protective cover 2 on the front, rear, and upper sides, thus covering the internal structure in all directions.

[0035] The protective cover 2 is linearly slidably connected to the vehicle body 1. A lead screw 9 and a second motor 10 driving the lead screw 9 are mounted on the vehicle body 1. The protective cover 2 is connected to a threaded sleeve 11 that is threadedly engaged with the lead screw 9. The lead screw 9 is rotatably mounted inside a housing 15 on the upper rear side of the vehicle body 1. The second motor 10 is mounted on the upper rear side of the vehicle body 1 to drive the lead screw 9 to rotate. The threaded sleeve 11 has a block-shaped structure with a central internal threaded through hole. The lead screw 9 passes through the internal threaded through hole of the threaded sleeve 11. When the lead screw 9 rotates forward and backward, it drives the threaded sleeve 11 to move linearly back and forth, thereby realizing the lateral movement of the protective cover 2 and the roller brush 4.

[0036] In this embodiment, to ensure the straightness and stability of the lateral movement of the protective cover 2 and the roller brush 4, a slide rail is connected to the protective cover 2, and a slide block is connected to the vehicle body 1. The slide rail and the slide block slide in a linear sliding fit. Slide blocks are provided on the bottom and top inner sides of the housing 15, and slide rails that cooperate with the slide blocks are connected to the bottom and middle of the protective cover 2.

[0037] Specifically, the bottom of the protective cover 2 is connected to a base 6, which extends into the bottom of the chassis 15. The lower side of the base 6 is connected to two parallel first slide rails 7. The upper rear side of the vehicle body 1 is provided with two rows of several first slide blocks 8. The first slide rails 7 slide in a straight line along the first slide blocks 8 to ensure the straightness and stability of the bottom of the protective cover 2 during movement.

[0038] A threaded sleeve 11 is connected to the lower middle part of the base 6. The threaded sleeve 11 drives the bottom of the protective cover 2 to move linearly through the base 6. An upper support 12 is connected to the middle of the protective cover 2. The upper support 12 extends into the inner top of the chassis 15. The upper support 12 is connected to two second slide rails 13. Several second slide blocks 14 are provided on the inner top of the chassis 15. The second slide rails 13 move linearly along the second slide blocks 14 to ensure the linearity and stability of the upper middle part of the protective cover 2.

[0039] The edge of the cover 2 is provided with several water spray heads 23. The water spray heads 23 are evenly distributed along the two vertical edges of the cover 2, spraying water or cleaning liquid toward the side of the large vehicle. Combined with the roller brush 4, the large vehicle can be scrubbed, which can improve the cleaning effect and remove stubborn stains from the vehicle surface.

[0040] In this embodiment, a water tank 22 supplying water to the spray nozzle 23 is located in the middle of the vehicle body 1. The water tank 22 is situated on the upper side of the vehicle body 1, below the battery box. The water tank 22 contains a mesh-like partition with several water-guiding notches at its lower end. The partition enhances the strength of the water tank 22, supports the upper battery box, seat 21, and driver, and prevents deformation of the water tank 22. During vehicle movement, it also reduces water ripples and vibrations, thereby minimizing the impact on the stability of the vehicle body 1. The notches allow the liquid in the water tank 22, separated by the partition, to flow freely.

[0041] Water from the water tank 22 is supplied to the spray head 23 via a water pump and water pipes (not shown in the attached drawings). Using a water pump and water pipes for water supply is existing technology and can be arranged reasonably as needed. In this embodiment, an electrical control box with a door is located on the upper part of the casing 15; a side door is located on the lower side of the casing 15, inside which the water pump is installed. Opening the side door allows observation of the water pump's status.
