Description

Technical Field

[0001] The invention relates to the field of unmanned car washing, and in particular to a multi-angle freely changeable cleaning brush and unmanned car washing equipment. Background Art

[0002] Unmanned car washing equipment refers to equipment that can automatically complete vehicle cleaning without the intervention of car washers. Due to its advantages such as low cleaning cost and high efficiency, the use of unmanned car washing machines for vehicle cleaning is gradually becoming the first choice for car owners.

[0003] In order to achieve the effect of unmanned car washing, the unmanned car washing equipment needs to include at least a cleaning brush assembly, a water washing assembly and a control assembly, among which the cleaning brush assembly is an indispensable car washing device, and the quality of the car washing effect and the efficiency of the car washing depend largely on the cleaning brush assembly. At present, the common unmanned car washing machine is a gantry-type reciprocating car washing equipment. Due to the structural characteristics of the gantry-type reciprocating unmanned car washing equipment itself, the range of movement of the cleaning brush assembly therein is limited, which leads to the limitation of the car washing effect or the slowdown of the car washing efficiency. For example, the cleaning brush in the current gantry-type reciprocating unmanned car washing equipment changes in height within the height limit of the gantry frame. In order to be able to wash large vehicles, the height of the gantry frame needs to be increased, which leads to an increase in the cost of the unmanned car washing equipment and increases the operating cost of the unmanned car washing equipment; for another example, the rotation angle of the cleaning brush of the current gantry-type reciprocating unmanned car washing equipment is also limited by the structure of the equipment itself. In order to wash the vehicle, a top brush is often required, which also invisibly increases the car washing cost of the unmanned car washing equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-angle freely changeable cleaning brush and an unmanned car washing device. The multi-angle freely changeable cleaning brush can freely change the angle of three axes to ensure that the brush can brush any surface between 60CM-220CM in height, and the brush can be used to brush the car model at any angle between -30 degrees and 150 degrees. The brush can adjust the appropriate brushing angle for different surfaces to brush the car, thereby ensuring the vehicle cleaning effect.

[0005] The object of the present invention is to provide a multi-angle freely changeable cleaning brush and an unmanned car washing device. The multi-angle freely changeable cleaning brush has a highly compact structure, so that the volume size of the unmanned car washing device equipped with the multi-angle freely changeable cleaning brush is greatly reduced.

[0006] In order to achieve any of the above invention purposes, the present invention provides a multi-angle freely changeable cleaning brush, which at least includes: a lifting component, a brush body position control component and a cleaning brush connected in sequence, wherein the lifting component at least includes a lifting electric cylinder arranged in the height direction, and the brush body position control component at least includes a translation component, a lifting component and a rotation 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 rotation component is connected to control the cleaning brush.

[0007] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0008] 1. The multi-angle freely changeable cleaning brush is placed in the equipment shell, including a lifting component that can move and change in the height direction, and a brush body position control component that controls the position change of the cleaning brush in the horizontal direction and the lifting angle. This makes the multi-angle freely changeable cleaning brush have flexible and changeable cleaning angles. It can brush the car model at any angle, adjust the appropriate brushing angle for different surfaces, and ensure the vehicle cleaning effect.

[0009] 2. The angle of the multi-angle freely changeable cleaning brush can be freely changed, so that a single unmanned car washing device equipped with the multi-angle freely changeable cleaning brush can complete the cleaning task of the entire vehicle to be washed, thereby reducing the cost of car washing.

[0010] 3. The lifting assembly of the multi-angle freely changeable cleaning brush and the brush body control position control assembly can reduce the floor space occupied by the cleaning brush, thereby reducing the volume size of the unmanned car washing equipment and increasing the scope of application of the unmanned car washing equipment.

DETAILED DESCRIPTION

[0016] 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.

[0017] 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.

[0018] 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.

[0019] The multi-angle freely changing cleaning brush provided by the technical solution can be applied to unmanned car washing equipment. The multi-angle freely changing cleaning brush has flexible and changeable cleaning angles, and can brush the car model at any angle. The appropriate brushing angle can be adjusted for different surfaces to brush the car to ensure the vehicle cleaning effect; the unmanned car washing equipment with the multi-angle automatically changing cleaning brush has the advantages of highly compact structure and small size.

[0020] Specifically, the multi-angle freely changeable cleaning brush provided by the present solution at least includes a lifting component 20, a brush body position control component 30 and a cleaning brush 40 connected in sequence, wherein the lifting component 20 includes at least a lifting electric cylinder 22 arranged in the height direction, and the brush body position control component 30 includes at least a translation component 33, a lifting component 32 and a rotating component 31 connected in sequence, wherein the translation component 33 is arranged parallel to the horizontal plane, the lifting component 32 makes an arc motion relative to the vertical plane and the horizontal plane, and the rotating component 31 is connected to control the cleaning brush 40.

[0021] The multi-angle freely changing cleaning brush is connected and controlled by the control board. The lifting component 20 lifts and lowers the cleaning brush 40 in the height direction after obtaining the lifting command of the control board. The brush body position control component 30 controls the cleaning brush 40 to perform three-axis movement after obtaining the position adjustment command of the control board. The rotating component 31 controls the cleaning brush 40 to rotate after obtaining the working command of the control board.

[0022] In addition, the present solution provides an unmanned car washing device using the multi-angle freely changing cleaning brush, including a device housing 10, a control panel, and the multi-angle freely changing cleaning brush mentioned thereon, wherein the multi-angle freely changing cleaning brush is placed in the device housing 10.

[0023] Specifically, the lifting assembly 20 adopts a multi-stage electric cylinder design. The lifting assembly 20 includes a multi-stage lifting cylinder 22 arranged in the height direction and a connecting cross bar 21 connecting the lifting 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.

[0024] In order to ensure the stability and symmetry of the lifting assembly 20 during lifting, the lifting cylinders 22 are symmetrically placed 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, so that the stability of the overall structure can also be ensured. In the specific embodiment of this scheme, a three-stage lifting cylinder 22 is selected, and the lifting height of the lifting cylinder 22 is controlled to be 60CM-220CM, so that the cleaning brush 40 can brush any surface between 60CM-220CM.

[0025] 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.

[0026] 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 lift freely 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 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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).

[0033] 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.

[0034] 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 .

[0035] 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.

[0036] 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 unmanned car washing equipment, so that the volume size of the unmanned car washing equipment is further optimized.

[0037] In summary, the lifting assembly 20 of the 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 unmanned car washing equipment can maintain the most suitable angle and posture to wash the vehicle according to the structural state of the vehicle body surface to ensure the washing fit.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In addition, the device housing 10 includes a side wall body 11 and a top cover 13, wherein the side wall body 11 forms a receiving chamber 12 with at least one opening, the top cover 13 is placed on the top side of the side wall body 11, and the multi-angle freely changeable cleaning brush is placed in the receiving chamber 12. At this time, when the multi-angle freely changeable cleaning brush is stored in the receiving chamber 12, the size of the unmanned car washing device is only controlled to the size of the device housing 10.

[0043] 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.
