Description

Technical Field

[0001] The present invention relates to the field of unmanned car washing machines, and in particular to a walking type unmanned car washing device. Background Art

[0002] An unmanned car wash machine refers to a device that can automatically clean a vehicle without the intervention of a car washer. Due to its advantages such as low cleaning cost and high efficiency, the use of unmanned car wash machines for vehicle cleaning is gradually becoming the first choice for car owners.

[0003] However, the common unmanned car wash machines on the market currently have certain limitations in their own structure, which still leads to limitations in practical applications. Specifically, the common unmanned car wash machine is a gantry-type car wash machine, and the whole machine is fixed in a specific place for car owners to use. The size of the gantry-type car wash machine is very large. Usually, the size of a gantry-type car wash machine reaches 2.7 meters in length, 3.6 meters in width, and 3 meters in height, which leads to restrictions on the optional application sites of the unmanned car wash machine and increased operating costs. For example, the current gantry-type car wash machine cannot be set up in a height-restricted underground garage, and renting a public place also requires paying a large site fee every year based on the area occupied.

[0004] The gantry car washers used outdoors are also inconvenient to install. The gantry car washers include a running track, a gantry frame placed on the running track, and various car washing equipment, and weigh up to about 2.5 tons. These characteristics bring many inconveniences to the installation and transportation of the gantry car washers. For example, the track structure of the current gantry car washers requires the selection of a flat road surface or the flattening of the road surface before installation.

[0005] In summary, unmanned car washing has become a trend in the car washing industry, but the current gantry car washing machines have limitations in actual use. Summary of the invention

[0006] The purpose of the present invention is to provide a walking unmanned car washing equipment that replaces the traditional gantry car washing machine to realize intelligent unmanned car washing. The walking unmanned car washing equipment has a highly streamlined structure, can move freely without tracks, automatically search for vehicles, and intelligently and accurately bypass the vehicles for vehicle washing.

[0007] In order to achieve any of the above invention purposes, the present invention provides a walking unmanned car washing device, including; an equipment housing, a control panel, a lifting component connected and controlled by the control panel, a brush body position control component, a cleaning brush and a moving component; wherein the moving component is placed at the bottom of the equipment housing, wherein the lifting component, the brush body position control component and the cleaning brush are connected in sequence and placed in the equipment housing, the lifting component at least includes a lifting electric cylinder arranged in the height direction of the equipment housing, the brush body position control component at least includes a translation component, a lifting component and a rotating component connected in sequence, wherein the translation component is arranged parallel to the horizontal plane, the lifting component makes an arc motion relative to the vertical plane and the horizontal plane, and the rotating component is connected to control the cleaning brush.

[0008] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0009] 1. This walking unmanned car washing equipment is different from the traditional gantry car washing machine. It integrates various car washing components in a modularized manner. The size and volume are 25% smaller than the traditional gantry car washing machine. It requires a small footprint and has low site height requirements. It can easily enter underground garages and other scenes, expanding the application scenarios of unmanned car washing equipment.

[0010] 2. It can be moved freely without being fixed in a specific place. It can also be moved tracklessly to run freely on various sites. It can run on different road surfaces such as cement, asphalt, and gravel roads without any ground modification.

[0011] 3. The lifting assembly and brush position control assembly of the three-axis linkage supporting cleaning brush assembly, the angle of the cleaning brush assembly can be changed arbitrarily between -30 degrees and 150 degrees, so that the cleaning brush assembly of the walking unmanned car washing equipment can clean any vehicle model and ensure the vehicle cleaning effect.

[0012] 4. A series of positioning sensor components are set up so that the walking unmanned car washing equipment can accurately reach the cleaning position, so that the car washing equipment can cooperate with the vehicle to be washed, rather than the vehicle to be washed cooperating with the car washing equipment. This improves the user experience of the car washing users and makes the unmanned car washing equipment and the vehicle to be washed fit more closely. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 belong to the scope of protection of the present invention.

[0021] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] The walking unmanned car washing equipment of the present technical solution provides an unmanned car washing solution which is completely different from the traditional gantry-type unmanned car washing machine. The walking unmanned car washing equipment can locate the vehicle in the car washing area, move to the corresponding cleaning position and intelligently and accurately circle the vehicle for brushing, thereby realizing an unmanned car washing solution in which the car washing equipment cooperates with the vehicle to be washed. Moreover, the walking unmanned car washing equipment integrates various types of car washing equipment to achieve a highly streamlined structure, thereby expanding the application areas of the unmanned car washing equipment.

[0024] The walking type unmanned car washing device provided by the present invention at least comprises: a device housing 10, a control panel, a lifting assembly 20 connected and controlled by the control panel, a brush body position control assembly 30, a cleaning brush 40 and a moving assembly 60, wherein the moving assembly 60 is placed at the bottom of the device housing 10 to realize the movement of the walking type unmanned car washing device when the moving instruction of the control panel is obtained, wherein the lifting assembly 20, the brush body position control assembly 30 and the cleaning brush are sequentially connected and placed on the device housing 10, and the lifting assembly 20 at least comprises a lifting motor arranged in the height direction of the device housing 10. The cylinder 22 is used to lift the cleaning brush 40 in the height direction after obtaining the lifting instruction of the control board. The brush body position control component 30 at least includes a translation component 33, a lifting component 32 and a rotation component 31 connected in sequence, wherein the translation component 33 is arranged parallel to the horizontal plane, and the lifting component 32 performs an arc motion between the vertical plane and the horizontal plane, or in other words, the lifting component 32 performs a lifting motion in the height direction. The rotation component 31 is connected to control the cleaning brush 40. The brush body position control component 30 controls the cleaning brush 40 to perform three-axis motion after obtaining the position adjustment instruction of the control board.

[0025] The walking unmanned car washing equipment provided in this solution can locate the position of the vehicle to be washed and then move to the corresponding cleaning position through the moving component 60, then adjust the position of the cleaning brush 40 through the lifting component 20 and the brush body position control component 30, and rotate the cleaning brush 40 through the rotating component 31 to clean the vehicle to be washed.

[0026] Of course, the walking type unmanned car washing equipment also includes a water washing component (not shown in the figure) and an energy supply component. The water washing component at least includes a water supply tank and a water supply pipe placed on the walking type unmanned car washing equipment. The water supply pipe transmits the water in the water supply tank to the outside, and cooperates with the cleaning brush 40 to achieve the cleaning of the vehicle to be washed. The energy supply component provides energy support for the equipment in the walking type unmanned car washing equipment. The specific structure of the water washing component and the energy supply component, as well as the technology of cooperating with the water washing component and the cleaning brush 40 are technical contents well known to technical personnel in this field, and reference can be made to the corresponding structure in the gantry type car washing machine. The applicant will not explain it in this scheme.

[0027] Unlike the water washing components in the existing gantry-type unmanned car washing equipment, the water supply tank in the walking-type unmanned car washing equipment of this solution is equipped with a water level sensor. When the water level sensor finds that the water level in the water supply tank is lower than the threshold, it transmits a signal to the control board. The control board transmits the water replenishment path information to the mobile component 10. The mobile component 10 walks to the corresponding water replenishment location for water replenishment according to the water replenishment path information. Of course, water replenishment can be manual or self-replenishment. If self-replenishment is adopted, a self-replenishment device is provided at the water replenishment location. The walking-type unmanned car washing equipment determines the interface position of the self-replenishment device through laser radar and visual sensors (the content of the positioning sensor component will be explained below), and then automatically connects to the interface for water replenishment.

[0028] Unlike the energy supply components in the existing gantry-type unmanned car washing equipment, the energy supply component of this solution has its own energy sensor. When the energy sensor finds that the energy in the energy supply component is insufficient, it transmits a signal to the control panel. The control panel transmits the energy supply route information to the mobile component 10. The mobile component 10 walks to the corresponding energy supply point for energy supply according to the energy supply route information. If the self-powered method is adopted, a self-powered device is provided at the energy supply point. The walking unmanned car washing equipment determines the interface position of the self-powered device through a laser radar and a visual sensor, and then automatically connects to the interface for power replenishment. The principle of self-water replenishment and self-power replenishment is the same as the principle logic of the common sweeping robots on the market, and will not be elaborated here.

[0029] The moving assembly 10 includes a moving wheel and a control motor (not shown) connected to control the moving wheel. The control motor is controlled by the control board. The moving wheel moves forward and backward under the control of the control motor, turns at any angle, and rotates on the spot, thereby realizing the free movement of the walking unmanned car washing equipment. The control and movement principles of the moving wheel are also well known to those skilled in the art.

[0030] In a specific embodiment of the present scheme, the mobile component 10 includes at least a driving wheel 62 and a driven wheel 61, wherein the driving wheel 62 is arranged at the bottom of the device housing 10, and the driven wheel 61 is arranged at the side position of the mobile component 10, and the driving wheel 62 is connected to the control motor to move under the control of the control motor to drive the movement of the driven wheel 61. Preferably, the driving wheel 62 is arranged at the center position of the bottom of the device housing 10 to ensure walking stability.

[0031] Specifically, the mobile assembly 10 includes at least two driving wheels 62 and four driven wheels 61 located at the four corners, wherein the two driving wheels 62 are controlled by two independent control motors, and the driven wheels 61 are universal driven wheels. Through the differential control of the two driving wheels 62, the walking unmanned car washing device can move forward and backward, turn at any angle, and rotate in place. For example, if you want to control the walking unmanned car washing device to turn right, you can control the driving wheel 62 on the left to run faster than the driving wheel 62 on the right.

[0032] In some embodiments, the mobile component 60 of the driving type unmanned car washing equipment provided by the present solution obtains remote vehicle positioning information and then moves to the cleaning position, wherein the vehicle positioning information includes the walking path information of the unmanned car washing equipment, or the control panel converts the vehicle positioning information to obtain the walking path information, and the control motor of the mobile component 10 controls the driving wheel 62 and the driven wheel 61 according to the walking path information.

[0033] In other preferred embodiments, the walking unmanned car washing device can self-locate the spatial position of the vehicle in the car washing area to obtain the vehicle positioning information; or, the walking unmanned car washing device can self-locate the spatial position of the vehicle in the car washing area and calibrate it in combination with the vehicle positioning information provided by the remote end.

[0034] At this time, the walking unmanned car washing equipment of this scheme includes a positioning sensor component 50, wherein the positioning sensor component 50 at least includes a laser radar, a visual sensor and an ultrasonic radar (the specific radar structure and the setting position are not drawn in the figure), wherein the laser radar and the visual sensor identify and locate the spatial position of the vehicle in the car washing area, thereby obtaining the vehicle positioning information, and the vehicle positioning information is transmitted to the control board, and the walking path information is obtained after processing and analysis, and the walking path information is then provided to the mobile component 60 to realize the movement of the unmanned car washing equipment, wherein the ultrasonic radar identifies obstacles of the unmanned car washing equipment during its movement, and after obtaining the obstacle information, it is transmitted to the control board, and the walking path information is updated after processing and analysis.

[0035] Laser radar emits a detection laser beam to the target, and then compares the target echo reflected from the target with the transmitted signal. After appropriate processing, it can obtain relevant information about the target, such as target distance, direction, height, speed, attitude, and even shape parameters. This solution uses laser radar to obtain target identification of the vehicle to be washed. The identification content includes not only the position of the vehicle to be washed but also the appearance and shape of the vehicle to be washed, which is convenient for targeted washing in subsequent car washing. The visual sensor used in this solution uses a binocular structured light 3D visual sensor, which can play the same function as laser radar. The difference between the two is that the principles of obtaining the spatial position relationship of the vehicle are different, and each has advantages and disadvantages in practical applications.

[0036] It is worth mentioning that in this solution, both the laser radar and the visual sensor play the role of identifying vehicle targets. In the preferred embodiment of this solution, two sensors with similar functions are combined, and the control panel has a built-in fusion algorithm. The fusion algorithm fuses the data of the two types of sensors to avoid the problem of inaccurate positioning caused by the failure of a sensor under special circumstances. In other words, in actual applications, there will be multiple spatial coordinate information transmitted by multiple sensors, and there are certain differences between each spatial coordinate information. The fusion algorithm will compare and obtain accurate information from multiple information. For example, the fusion algorithm obtains the position information a obtained by the laser radar and the position information b obtained by the visual sensor, determines whether the position information a and the position information b are consistent or have position difference data, and selects accurate information from them to obtain more accurate positioning information.

[0037] The vehicle positioning information obtained by the laser radar and visual sensor can not only be used to formulate walking path information, but also to control the distance between the walking unmanned car wash equipment and the vehicle to be washed. Specifically, the walking unmanned car wash equipment reaches the vicinity of the vehicle to be washed and begins to detect the distance between itself and the vehicle. Through the feedback data of the laser radar and binocular vision sensor, the walking unmanned car wash equipment obtains the distance information between itself and the surface of the vehicle body. If the distance is too close, the walking unmanned car wash equipment controls the movement direction of the mobile platform and moves slightly away from the vehicle until the distance meets the required position. Through continuous and precise fine-tuning, the walking unmanned car wash equipment can stably maintain a certain distance from the vehicle to be washed, allowing the vehicle to bypass.

[0038] The feedback data from the visual sensor and ultrasonic radar sensor can also help the unmanned car wash equipment analyze moving objects or obstacles on its path. Once the data feedback indicates that the obstacle may collide with the unmanned car wash equipment, the unmanned car wash equipment will automatically stop until the obstacle disappears. Specifically, the ultrasonic radar sensor uses ultrasonic waves to obtain whether there is an obstacle on the path, and the visual sensor determines whether the obstacle is the target vehicle. If it is not the target vehicle, it determines that the obstacle exists, and the control board updates the walking path information. The update here means stopping the operation, and the update here can even be retreating.

[0039] That is, the positioning sensor component 50 provided in this solution can obtain the positioning information of the vehicle, and then formulate or update the walking path information of the unmanned car washing equipment, and can also obtain obstacles that may be encountered on the way to update the walking path information. After obtaining the walking path information, the mobile component 60 walks to the washing position near the vehicle to be washed, and the positioning sensor component 50 ensures that a certain distance is maintained between the walking unmanned car washing equipment and the vehicle to be washed to avoid damaging the vehicle to be washed. In other words, the cooperation of the positioning sensor component 50 and the mobile component 60 realizes the washing method of the unmanned car washing equipment in cooperation with the vehicle to be washed.

[0040] In addition, a gyroscope is provided in the walking unmanned car washing equipment mentioned above. The gyroscope obtains the acceleration information of the walking unmanned car washing equipment and determines the walking speed based on the acceleration information. The gyroscope is used to determine its own walking trajectory and determine its own real-time spatial coordinate position. That is, after the original position of the walking unmanned car washing equipment of this scheme is set, the gyroscope obtains the walking path of the walking unmanned car washing equipment and is used to calculate and determine the real-time position information of the walking unmanned car washing equipment. However, the gyroscope will have cumulative errors when the walking unmanned car washing equipment travels a long distance. At this time, the binocular vision sensor installed on the walking unmanned car washing equipment will regularly identify and locate the markers in the on-site environment to correct the position deviation of the walking unmanned car washing equipment.

[0041] The walking unmanned car washing device moves to the washing position near the vehicle to be washed by the moving component 60, or the cooperation of the moving component 60 and the positioning sensor component 50, and circumvents the vehicle to complete the washing of the vehicle. Moreover, in this solution, the walking unmanned car washing device can be moved to the vicinity of the vehicle to be washed by the moving component 60, so that the trackless movement of the walking unmanned car washing device can be realized, and it can be directly operated on various venues without any ground modification, and can be operated on different road surfaces such as cement ground, asphalt road, gravel road, etc.

[0042] A major feature of the walking type unmanned car washing equipment provided by this solution is that its structure is highly streamlined and is centrally stored when it is not in working state, so that the volume of the walking type unmanned car washing equipment is 25% smaller than that of the gantry type unmanned car washing machine.

[0043] Specifically, the device housing 10 of the present scheme includes a base 11, a side wall body 13, an opening and closing door 14 and a top cover 15, wherein the side wall body 13 is placed on the base 11 to form a accommodating chamber 12 with at least a single-side opening, the opening and closing door 14 is movably connected to the side wall body 13 to change its position between a door closed state and a door open state, and the opening and closing door 14 moves in the direction of the single-side opening, so that when the opening and closing door 14 is in the door closed state, the walking unmanned equipment is in a closed state, the top cover 15 is placed on the top side of the side wall body 13, the lifting assembly 20, the brush body position control assembly 30 and the cleaning brush 40 are stored in the accommodating chamber 12, so that the size of the walking unmanned car washing equipment in the non-car washing state can be controlled to the size of an equipment housing 10.

[0044] The lifting assembly 20 adopts a multi-stage electric cylinder design. Specifically, the lifting assembly 20 includes a lifting electric cylinder 22 arranged in the height direction and a connecting cross bar 21 connecting the electric cylinder 22. The connecting cross bar 21 is connected to the brush body position control assembly 30, so that the lifting assembly 20 can drive the cleaning brush 40 to move in the height direction by driving the brush body position control assembly 30.

[0045] In order to ensure the stability and symmetry of the lifting assembly 20 during lifting, the lifting cylinders 22 are symmetrically arranged on both sides of the cleaning brush 40, and the lifting cylinders 22 on both sides are synchronously driven to achieve the change of the height position of the cleaning brush 40, which can also ensure the stability of the overall structure. In the specific embodiment of this scheme, a three-stage lifting cylinder 22 is selected so that the cleaning brush 40 can brush any surface between 60CM and 220CM in height.

[0046] In order to optimize the size structure, the connecting crossbar 21 of the present solution is connected to the position near the top of the lifting cylinder 22, and the connecting crossbar 21 crosses the position of the cleaning brush and connects to the translation assembly 33. The top of the lifting cylinder 22 is connected to the top cover 15 to drive the top cover 15 to change position together, which has the advantage of preventing the top cover from affecting the position adjustment of the cleaning brush 40.

[0047] It is worth mentioning that the height of the traditional gantry car washing machine must be at least higher than the height of the vehicle itself, so that the vehicle can enter the gantry car washing machine for washing; and the top of the traditional gantry car washing machine is fixed, and the cleaning brush is difficult to freely lift and lower inside it, resulting in the height of the gantry car washing machine being directly related to the cleaning height, which leads to the height of the gantry car washing machine being relatively high and difficult to be used in places with limited height. However, the lifting component 20 of the walking unmanned car washing equipment of this solution greatly reduces the height of the whole machine, and the volume size of the whole machine is also well optimized.

[0048] The translation assembly 33 of the brush position control assembly 30 adopts a synchronous pulley mechanism to drive the cleaning brush 40 to move forward or backward in the horizontal direction to achieve the operation of approaching or moving away from the vehicle.

[0049] Specifically, the translation assembly 30 includes a translation main board 331, a gear belt 332, a pulley 333, a translation sub-plate 334 and a driving motor (not shown in the figure), wherein the translation main board 331 is connected to the connecting cross bar 21, the translation sub-plate 334 is connected to the lifting assembly 32, and the translation sub-plate 334 and the translation main board 331 are translated by synchronous pulley transmission. Different from other traditional methods, the synchronous pulley transmission can carry heavier transmission objects and control the parallelism of the transmission. The cleaning brush 40, the lifting assembly 32, the rotating assembly 31 and other components of this scheme have considerable weight, so this scheme adopts the synchronous pulley transmission method for translation.

[0050] The gear belt 332 is arranged on the bottom side of the translation main plate 331, the pulley 333 is connected to the translation secondary plate 334, and the pulley 333 is connected to the driving motor, wherein the inner tooth structure of the gear belt 332 and the outer tooth structure of the pulley 333 match, so that the pulley 333 can move along the designed stroke in the gear belt 332.

[0051] It is worth mentioning that the translation sub-plate 334 of the present solution moves along the horizontal direction, and the height of the unmanned car washing equipment is set in the vertical direction.

[0052] The lifting assembly 32 includes a lifting plate 321, a lifting motor 322 and a bearing 323, wherein the lifting plate 321 is movably connected to the translation sub-plate 334, the lifting plate 321 is connected to the lifting motor 322 through the bearing 322, the rotating assembly 31 connected to the cleaning brush 40 is connected to the lifting plate 321, and the lifting motor 322 drives the lifting plate 321 to make an arc motion relative to the vertical plane and the horizontal plane, thereby driving the position change of the cleaning brush 40.

[0053] The lifting assembly 32 drives the bearing 323 to move through the lifting motor 322, thereby realizing the lifting and leveling action of the cleaning brush 40 in the vertical direction, and can maintain the posture of the cleaning brush 40 at any angle from -30 degrees to 150 degrees. Specifically, one side of the lifting plate 321 is connected to the lifting motor 322 through the bearing 323, and the output shaft of the lifting motor 322 controls the bearing 323 to make an arc motion between the relative vertical plane and the horizontal plane, and the movement range is between -30 degrees and 150 degrees (with the vertical line at a height of 0 degrees).

[0054] In this solution, the bearing 323 of the lifting plate 321 is movably placed in the fixed sleeve 324, and the fixed sleeve 324 is connected to the translation sub-plate 334, so that the lifting component 32 can realize the connection with the translation component 33 and realize lifting at the same time. Specifically, the translation sub-plate 324 includes a horizontal plate and vertical plates on both sides, wherein the vertical plates are vertically arranged downward relative to the horizontal plate, and the fixed sleeve 324 passes through the vertical plates and connects to the vertical plates at the same time, and the lifting plate 321 is placed in the space formed between the vertical plates on both sides. That is, the lifting motor 322 drives the bearing 323 to move in the fixed sleeve 324, and since the bearing 323 is connected to the lifting plate 321, the lifting plate 321 also moves accordingly, and the fixed sleeve 324 is connected to the translation sub-plate 333, thereby realizing the connection between the lifting component 32 and the translation component 33.

[0055] The rotating assembly 31 includes a rotating motor 311 and a motor output shaft 312 connected to the rotating motor 311 , wherein the motor output shaft 312 is connected to the cleaning brush 40 and drives the cleaning brush 40 to rotate under the action of the rotating motor 311 .

[0056] The rotating component 31 is connected to the lifting component 32. Specifically, a through hole is formed on the lifting plate 321 for the motor output shaft 312 to pass through. The rotating motor 311 is placed on the upper side of the lifting plate 321 and connected to the lifting plate 321, thereby realizing the connection between the rotating component 31 and the lifting component 20.

[0057] It is worth mentioning that the lifting motor 322 is placed on the vertical plate side of the translation sub-plate 334, and the rotating motor 311 is placed in the space inside the vertical plates on both sides. That is, the rotating assembly 30 fully utilizes the distance between the translation sub-plate 334 and the lifting plate 321, and fully utilizes the space of the walking unmanned car washing equipment, so that the volume size of the walking unmanned car washing equipment is further optimized.

[0058] In summary, the lifting assembly 20 of the walking unmanned car washing equipment provided by the present solution realizes the movement of the washing brush 40 in the height direction, the translation assembly 33 realizes the movement of the washing brush 40 in the horizontal direction, the lifting assembly 32 realizes the lifting of the washing brush 40 in the height direction, and the rotating assembly 31 realizes the operation of the washing brush 40. Through the joint control of several structures, the walking unmanned car washing equipment can maintain the most suitable angle posture to wash the vehicle according to the structural state of the vehicle body surface to ensure the washing fit.

[0059] For example, when the car body needs to be washed, the brush can be kept in a low vertical position; when the windows need to be washed, the brush is kept in a high position and maintains an inclination angle of about -10 degrees to fit the windows; when the roof needs to be washed, the brush is kept in a horizontal state and moves up and down adaptively according to the outer contour of the roof.

[0060] It is also worth mentioning that the translation assembly 33 of the present solution can make the cleaning brush 40 move outward relative to the device housing 10, thereby providing sufficient lifting space for the cleaning brush 40, and realizing the position change of the cleaning brush 40 at multiple angles to better meet the requirements of car washing. In addition, the lifting assembly 20 and the brush body position control assembly 30 of the present solution can be controlled and driven at the same time.

[0061] The cleaning brush 40 provided in this solution includes a bristle rod 42 and bristles 41 disposed on the outer peripheral side of the bristle rod 42, wherein the bristle rod 42 is connected to the motor output shaft 312 to rotate under the action of the motor output shaft 312. The shape and size of the cleaning brush 40 is not larger than the accommodating chamber 12, so that the cleaning brush 40 can be accommodated in the accommodating chamber 12 when not in use.

[0062] In addition, in some embodiments, the bristles 41 are designed as a special trapezoidal structure, and the lateral width of the bristles 41 gradually decreases from the side close to the bristle rod 42 to the outside, so that the interval between the bristles 41 close to the outside is larger than the area of ​​the bristles 41 close to the inside. Such a design can improve the cleaning efficiency while reducing the production cost. At the same time, the trapezoidal shape of the bristles can also better brush the upper edge of the window, thereby increasing the degree of cleaning.

[0063] In addition, the walking unmanned car washing equipment provided by this solution is in a closed state when not in use, which can prevent the precision equipment in the walking unmanned car washing equipment from being damaged. This is also something that the current traditional gantry-type unmanned car washing machines cannot do. The current traditional gantry-type car washing machines still have equipment exposed to the external environment when not in use, which will inevitably cause unnecessary equipment damage in the long run.

[0064] The opening and closing door 14 of this solution can change its position between the door closed state and the door open state. Figure 3 As shown, the side walls 13 located on both sides of the equipment housing 10 form a sliding rail 131, and the opening and closing door 14 includes a sliding member 141, a door body 142, a door connecting member 143, a rotating motor 144 and a moving motor (not marked in the figure), wherein the sliding member 141 is connected to the moving motor and slides in the sliding rail 131 under the action of the moving motor, the rotating motor 144 is placed on the upper side of the sliding member 141, and the two end sides of the door connecting member 143 are respectively connected to the rotating motor 144 and the door body 142.

[0065] Specifically, in the embodiment of the present scheme, the sliding rail 131 passes through the side wall 13 on both sides, and the walking type unmanned car washing device includes two door bodies 142 disposed on both sides of the device housing 10. When the door body 142 is located at the corner position of the device housing 10 (a sensor is provided, which is not shown in the figure), the rotating motor 144 rotates to drive the door body 42 to rotate along the corner of the device housing 10, so that the door body 142 can be located at the front end side or the side end side of the device housing 10. Since the door body 142 is connected to the rotating motor 144 through the door connecting member 143, a small distance is separated between the door body 142 and the side wall 13, so that when the rotating motor 144 rotates the door body 142, the door body 142 will not touch the side wall 13. In addition, the moving motor is connected to the sliding member 141 through a synchronous pulley mechanism. When the door body 142 is already at the side end side of the side wall 13, the moving motor drives the sliding member 141 to slide forward and backward.

[0066] That is, when the walking unmanned car washing equipment provided by the present solution is on standby, the brush retracts inward, the opening and closing door 14 of the walking unmanned car washing equipment is in a closed state, and the entire walking unmanned car washing equipment is in a sealed state. When the vehicle needs to be washed, the rotating motor 144 rotates to drive the opening and closing door 14 to change between a closed state and an open state. At the same time, another moving motor on the opening and closing door 14 drives a synchronous pulley mechanism to pull the door back so that it can be parked on both sides of the walking unmanned car washing equipment.

[0067] In addition, the sides of the two door bodies 142 away from each other are provided with arc edges, which can play a sealing role when the door bodies 142 are in a closed state. The door body 142 is designed as a trapezoidal structure, and the side of the door body 142 close to the top cover 15 is an inclined side, and the inclined side is inclined downward. The front end side of the top cover 15 is provided with a front cover piece 151, wherein the front cover piece 151 is designed as an inverted triangle structure, and the inclination of the inclined triangle side of the inverted triangle is the same as the inclination of the inclined side of the door body 142. When the opening and closing door 14 is in a closed state, the door bodies 142 on both sides and the front cover piece 151 are connected to each other, which plays a role in covering the single-sided opening of the unmanned car washing equipment.

[0068] In a preferred embodiment of the present invention, the front cover 151 can rotate relative to the top cover 15, thereby affecting the movement of the brush position control assembly 30. The top cover 15 is connected to the lifting assembly 20, and the control motor of the translation assembly 33 controls the front cover 151 at the same time. When the lifting assembly 20 is lifted upward, the top cover 15 is driven to move upward, and the movement of the translation assembly 33 drives the front cover 151 to change.

[0069] In summary, the walking unmanned car washing device provided by the present solution changes state between a non-use state and a use state. When the walking unmanned car washing device is in the non-use state, the cleaning brush 40 is accommodated in the accommodating chamber 12, and the door bodies 15 on both sides are located at the front end side of the device housing 10 to close the device housing 10. When the walking unmanned car washing device is converted from the non-use state to the use state, the rotating motor 144 rotates the door body 142 to rotate the door body 142 from the front end side of the device housing 10 to the side end side. After the door body 142 is rotated to the side end side of the door body 142, the moving motor drives the synchronous pulley mechanism to pull the door body 142 backward so that the door body 142 is finally located at the side end side of the side wall body 13, and then the lifting assembly 20 and the brush body position control assembly 30 in the walking unmanned car washing device are adjusted to adjust the position of the cleaning brush 40.

[0070] In some preferred embodiments, the walking unmanned car washing equipment has a built-in heating device. The walking unmanned car washing equipment is provided with a temperature sensor, which is connected to the heating device. The temperature sensor is used to detect the ambient temperature. When the ambient temperature is lower than a set threshold, the heating device is triggered to heat up, so that the walking unmanned car washing equipment can use less electricity to ensure that the brush does not freeze, allowing it to provide car washing services outdoors at a lower cost in some extremely cold areas.

[0071] In addition, a waste water cavity is provided in the base 11 of the present embodiment, and water permeable holes are provided on the upper surface of the base 11 , so that the water on the bristles 42 falls into the base 11 by itself.

[0072] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
