[0028] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0029] 1 and 2 are schematic structural diagrams of an automatic cleaning device according to an exemplary embodiment. As shown in FIG. 1 and FIG. 2, the automatic cleaning device may be a vacuum cleaning robot, a mopping / brushing robot, a window climbing robot, etc., and the automatic cleaning device is composed of a moving platform 100, a sensing system 120, a control system 130, a driving system 140, a cleaning module 150, an energy system 160 and a man-machine interactive system 170.

[0030] The mobile platform 100 may be configured to automatically move a manipulation surface in a target direction. The manipulation surface may be a surface to be cleaned by an automatic cleaning device. In some embodiments, if the automatic cleaning device is a mopping robot, the automatic cleaning device works on a floor surface and the floor surface is the manipulation surface; if the automatic cleaning device is a window cleaning robot, the automatic cleaning device works on an exterior glass surface of a building and the glass is the manipulation surface; if the automatic cleaning device is a pipe cleaning robot, the automatic cleaning device works on an interior surface of a pipe and the interior surface of the pipe is the manipulation surface. Purely for illustrative purposes, a mopping robot is used as an example in the present application.

[0031] In some embodiments, the mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. The autonomous mobile platform means that the mobile platform 100 itself can automatically and adaptively make operational decisions in response to unexpected environmental inputs, while the non-autonomous mobile platform itself cannot adaptively make operational decisions in response to unexpected environmental inputs, but can operate according to a predetermined procedure or a certain logic. Correspondingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be determined autonomously by an automatic cleaning device, and when the mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by a system or manually. When the mobile platform 100 is an autonomous mobile platform, the mobile platform 100 is composed of a front part 111 and a rear part 110.

[0032] The sensing system 120 includes a positioning device 121 located above the mobile platform 100, a buffer 122 located in the front portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and other sensing devices such as ultrasonic sensors (not shown), infrared sensors (not shown), magnetometers (not shown), accelerometers (not shown), gyroscopes (not shown), and odometers (not shown), and provides various position information and moving status information of the equipment to the control system 130.

[0033] To more clearly describe the behavior of the automatic cleaning device, the following directions are defined. The automatic cleaning device can move on the floor surface by various combinations of movements about three mutually perpendicular axes defined by the moving platform 100: the lateral axis Y, the front-rear axis X, and the central vertical axis Z. The forward drive direction along the front-rear axis X is designated as "forward", and the rear drive direction along the front-rear axis X is designated as "rear". The lateral axis Y extends between the right and left wheels of the automatic cleaning device along an axis center substantially defined by the center point of the drive wheel assembly 141. Here, the automatic cleaning device can rotate about the Y axis. The automatic cleaning device is "pitch up" when the front part of the automatic cleaning device is tilted upward and the rear part is tilted downward, and is "pitch down" when the front part of the automatic cleaning device is tilted downward and the rear part is tilted upward. In addition, the automatic cleaning device can rotate about the Z axis. When the automatic cleaning device tilts to the right on the X-axis in the forward direction of the automatic cleaning device, it is referred to as "turning right," and when the automatic cleaning device tilts to the left on the X-axis, it is referred to as "turning left."

[0034] 2, cliff sensors 123 are provided at the bottom of the moving platform 100 and at the front and rear of the drive wheel assembly 141, which can prevent the automatic cleaning device from falling when retreating and prevent damage to the automatic cleaning device. The above "front" refers to the same side as the moving direction of the automatic cleaning device, and the above "rear" refers to the opposite side to the moving direction of the automatic cleaning device.

[0035] Specific types of position determining device 121 include, but are not limited to, a camera, a laser distance measuring device (LDS), and the like.

[0036] Each assembly in the sensing system 120 may operate independently or in concert to more precisely achieve its purpose and function. The cliff sensor 123 and ultrasonic sensor identify the surface to be cleaned and determine the physical characteristics of the surface to be cleaned, including the surface material, cleanliness, etc., which can be combined with a camera, laser ranging device, etc. for more precise determination.

[0037] For example, an ultrasonic sensor may be used to determine whether the surface to be cleaned is carpeted, and if the ultrasonic sensor determines that the surface to be cleaned is carpeted, control system 130 may control the automatic cleaning device to perform a carpet mode cleaning.

[0038] A buffer 122 is provided at the front portion 111 of the moving platform 100, and when the drive wheel assembly 141 propels the automatic cleaning device across the floor surface during the cleaning process, the buffer 122 detects one or more events (or objects) in the travel path of the automatic cleaning device via a sensor system, e.g., an infrared sensor, and the automatic cleaning device may detect the event (or object), e.g., an obstacle, a wall, through the buffer 122, and control the drive wheel assembly 141 in response to the event (or object), e.g., to move away from the obstacle.

[0039] The control system 130 is provided on a circuit board in the mobile platform 100 and includes a central processing unit, an application processor, etc., which communicates with a non-transitory memory such as a hard disk, a flash memory, a random access memory, etc., and the application processor receives the environmental information sensed by the multiple sensors from the sensing system 120, the obstacle information fed back from the laser ranging device, etc., draws an instant map of the environment in which the automatic cleaning device is installed using a positioning algorithm, such as SLAM, autonomously determines a travel path based on the environmental information and the environmental map, and then controls the operation of the drive system 140, such as forward, backward, and / or turning, according to the autonomously determined travel path. Furthermore, the control system 130 can determine whether to operate the cleaning module 150 to perform a cleaning operation based on the environmental information and the environmental map.

[0040] Specifically, the control system 130 combines distance information and speed information fed back from the buffer 122, cliff sensor 123, and sensing devices such as ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, etc. to comprehensively determine the current working state of the vacuum cleaner, such as threshold crossing, carpet riding, cliff position, upper or lower stuck, dust box full, lifted, etc., and gives specific next operation strategies according to different situations, so that the work of the automatic cleaning device can better meet the owner's requirements and provide a better user experience. Furthermore, the control system can plan the most efficient and reasonable cleaning path and cleaning method according to the instant map information drawn by SLAM, which can greatly improve the cleaning efficiency of the automatic cleaning device.

[0041] Based on the specific distance and angle information, such as x, y and θ components, the drive system 140 can execute the drive command to steer the automatic cleaning device to move across the floor surface. As shown in FIG. 2, the drive system 140 includes a drive wheel assembly 141, and the drive system 140 can simultaneously control the left and right wheels, and in order to more precisely control the device operation, the drive system 140 is preferably composed of a left drive wheel assembly and a right drive wheel assembly, respectively. The left and right drive wheel assemblies are symmetrically arranged along the horizontal axis defined by the moving platform 100.

[0042] In order for the automatic cleaning device to move more stably on the floor surface or have higher mobility, the automatic cleaning device may include one or more direction-changing assemblies 142, the direction-changing assembly 142 may be a driven wheel or a driving wheel, and its structural form includes but is not limited to a universal wheel, and the direction-changing assembly 142 may be located in front of the driving wheel assembly 141.

[0043] The energy system 160 includes rechargeable batteries such as nickel-metal hydride batteries and lithium batteries. The rechargeable batteries may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery voltage drop monitoring circuit, which are connected to a microcomputer control circuit. The host computer is connected to the charging pile for charging through a charging electrode provided on the side or bottom of the main body. If dust adheres to the exposed charging electrode, the plastic body around the electrode will melt and deform due to the cumulative effect of electric charge during the charging process, and the electrode itself will deform, resulting in a problem that charging cannot continue normally.

[0044] The man-machine interactive system 170 includes buttons on the host panel, which are available for the user to select functions, the man-machine interactive system 170 may further include a display screen and / or an indicator light and / or a speaker, which can display the current status or function options of the device to the user, and the man-machine interactive system 170 may further include a mobile phone client program. In the case of a route navigation type automatic cleaning device, a map of the environment in which the device is installed and the location of the device can be displayed to the user in the mobile phone client, which can provide the user with richer and more user-friendly function items.

[0045] As shown in FIG. 2, the cleaning module 150 may include a dry cleaning module 151 .

[0046] The dry cleaning module 151 includes a roller brush, a dust box, a fan, and an air outlet. The roller brush, which has some interference with the floor surface, sweeps up the dust on the floor surface to the front of the dust suction port between the roller brush and the dust box, and sucks it into the dust box through the suction gas generated by the fan that passes through the dust box. The dust removal capacity of a vacuum cleaner is indicated by the dust pickup efficiency (DPU), and the cleaning efficiency DPU is affected by the roller brush structure and material, the wind utilization rate of the duct consisting of the dust suction port, the dust box, the fan, the air outlet, and the connecting members between them, and the type and power of the fan, and is a complex system design issue. Compared with a normal plug-in dust suction device, the improvement of the dust removal capacity is of great significance for an automatic cleaning device with energy limitations. This is because the improvement of the dust removal capacity directly and effectively reduces the demand for energy, that is, a machine that can clean 80 square meters of floor surface on a single charge can be evolved to clean more than 180 square meters on a single charge. In addition, by reducing the number of charging times, the battery life is also greatly extended, and users can replace the battery less frequently. More intuitively and importantly, the improvement of the dust removal ability is the most obvious and important user experience, and the user can directly conclude whether the device cleans cleanly or wipes cleanly. The dry cleaning module may further include a side brush 152 having a rotating shaft, which is at an angle to the floor surface and moves the dirt to the roller brush area of ​​the cleaning module 150.

[0047] The automatic cleaning device may further include a wet cleaning module as a selectable cleaning module, configured to clean at least a portion of the operating surface using a wet cleaning method, where the wet cleaning module includes a water tank, a cleaning head, a driving unit, etc., where water in the water tank flows along a water channel to the cleaning head, and the cleaning head cleans at least a portion of the operating surface under the driving of the driving unit.

[0048] The pressing structure on the cover of the existing automatic cleaning device is complicated. For example, most of the existing cleaning device button structures are configured to provide a soft rubber bracket on a hard rubber bracket, bond the hard rubber button cap and the soft rubber bracket, and then bond the soft rubber bracket and the decorative cover of the upper housing of the device with double-sided adhesive tape, and fix the hard bracket to the upper housing on the lower side through a hook. Such a button assembly structure is complicated, has a large number of parts, requires a long assembly time, is complicated, and is expensive. Due to such a multi-layer structure, when attaching the soft rubber bracket to the decorative cover of the upper housing of the device, the positioning due to the soft rubber is easily misaligned, making it difficult to attach and remove the button, and when attaching and removing, the double-sided adhesive tape and the soft rubber are firmly bonded to each other, which easily causes damage to the double-sided adhesive tape and the soft rubber, and the button cannot be reused.

[0049] Therefore, the embodiment of the present application provides an automatic cleaning device, which simplifies unnecessary components of the button assembly of the automatic cleaning device, and the button assembly can realize the functions of sealing and waterproofing, light guiding and light blocking of the button with only one part, and at the same time, the assembly, disassembly and maintenance of the button can be made more convenient. Specifically, according to a specific embodiment of the present application, as shown in FIG. 3, the present application provides an automatic cleaning device, which includes a moving platform 100, the moving platform 100 is configured to automatically move the operation surface, the moving platform 100 includes a cover plate 200, the cover plate 200 constitutes at least a part of the moving platform 100, and the cover plate 200 is the upper housing of the moving platform 100 housing. Usually, the moving platform 100 includes a front half and a rear half, the front half is used to mount a touch button, etc., and the rear half is used to mount a dust box, etc. The automatic cleaning device further includes a button assembly 400, which is assembled to the cover plate 200, and is configured to form a control for the automatic cleaning device after being touched by a user, and the button assembly 400 includes a flexible button cap 410 and a hard bracket 420, and the button cap 410 is assembled to the bracket 420 to perform pressing. As shown in FIG. 4, the button cap 410 includes a button cap pressing part 411 and a button cap skirt 412, and the button cap skirt 412 is formed to surround the periphery of the button cap pressing part 411, and the button cap pressing part 411 and the button cap skirt 412 are of an upper and lower layer structure, and the button cap pressing part 411 is located on the upper layer of the button cap skirt 412, which is convenient for performing pressing, and the outer shape of the button cap pressing part 411 and the button cap skirt 412 may be a circle, a square, a rectangle, an ellipse, a D-shape or other shapes, but is not limited thereto. Here, as shown in FIG. 8a, the bracket 420 and the cover plate 200 are integrally molded, and the integral molding process is, for example, injection molding or press molding using a subsequent mold.The integrally molded bracket 420 eliminates the step of assembling the bracket and the cover plate 200 during the assembly process of the button assembly, avoids the problems of light leakage and water leakage caused by the assembly steps of too many parts, and at the same time improves the assembly efficiency of the button assembly. In some embodiments, as shown in Fig. 3 and Fig. 6, the automatic cleaning device further includes a decorative cover 300 provided on the top surface of the cover plate 200, which is generally configured to hide irregular parts on the top of the moving platform 100, and plays the role of aesthetics and protection. As shown in Fig. 6, the decorative cover 300 includes a mounting hole 310 that matches the shape of the button cap pressing part 411, and when the button cap 410 is assembled to the bracket 420, the button cap pressing part 411 penetrates the mounting hole 310, and at the same time, the edge of the mounting hole 310 is pressed against the button cap skirt 412. In this way, a tight connection between the mounting hole 310 and the button cap pressing portion 411 is achieved, which avoids the problems of light leakage and water leakage; optionally, the button cap pressing portion 411 passes through the mounting hole 310 with a tightening margin, which can further avoid the problems of light leakage and water leakage.

[0050] In some embodiments, as shown in FIG. 7, the cover plate 200 includes a button cap mounting portion 210 that substantially matches the contour of the button cap skirt, and the button cap mounting portion 210 is an approximately recessed structure, and the recessed contour may be circular, square, rectangular, elliptical or D-shaped, but is not limited thereto.

When performing the attachment, the button cap is first placed on the button cap mounting portion 210, and the decorative cover 300 is pressed against the button cap skirt 412. The upper surface of the button cap skirt 412 and the upper surface of the cover plate 200 are substantially flush with each other or slightly higher than the upper surface of the cover plate 200. The decorative cover 300 presses the upper surface of the button cap skirt 412 to achieve sealing, and optionally, after the decorative cover 300 presses the upper surface of the button cap skirt 412, the upper surface of the skirt is still slightly higher than the upper surface of the cover plate 200, thereby ensuring the sealing of the decorative cover 300.

[0051] In some embodiments, as shown in Fig. 8a, the button cap mounting portion 210 includes a groove 211 extending along the periphery of the edge, and the button cap skirt 412 includes a protruding edge 413 extending along the periphery of the edge. When the button cap 400 is attached to the bracket 420, the protruding edge 413 is inserted into the groove 211 to achieve a perfect seal between the soft rubber button cap 400 and the cover plate 200. Optionally, the protruding edge 413 is inserted into the groove 211 with an interference to achieve a perfect seal between the soft rubber button cap 400 and the cover plate 200. In some embodiments, as shown in FIG. 4, at least one of the inner and outer surfaces of the protruding edge 413 includes at least one protrusion 414, and the structure of the protrusion 414 is not limited and may be, for example, elongated, bump-shaped, etc. The protrusion 414 can further seal the soft rubber button cap 400 and the cover plate 200, enhance the waterproofness and light leakage prevention, and at the same time increase the strength of the button cap, increase the friction force of the contact surface, and prevent the installation from shifting.

[0052] In some embodiments, as shown in Fig. 9 and Fig. 10, the button cap mounting part 210 includes two button holes 212 arranged symmetrically, and the bracket 420 is integrally formed with the button hole. In some embodiments, for example, the bracket 420 includes a button ring 422 connected via at least one elastic arm 421, the button ring 422 is arranged at a substantially central position in the button hole, and connects the button ring 422 to the inner wall of the button hole via one or two elastic arms 421. The elastic arm 421 is arranged around the button ring 422 to increase the overall length of the elastic arm, improve elasticity, and increase the supporting strength by detouring, the button ring 422 is configured to be pressed by the button cap 400 to realize the button function, the elastic arm 421 is configured to return the button ring 422, and the button ring and the elastic arm are made of a hard but elastic material, such as hard rubber or hard plastic or metal.

[0053] In some embodiments, as shown in Figures 5a and 10, the button cap 400 further includes a first protrusion 417 and a second protrusion 418 on the bottom surface of the button cap pressing part 410, the bottom surface of the button cap 400 includes a recess 416 for receiving the first protrusion 417 and the second protrusion 418, the first protrusion 417 and the second protrusion 418 each include a columnar structure 4181 extending downward along the bottom surface of the button cap pressing part and a cone-shaped structure 4182 extending downward along the columnar structure, the columnar structure 4181 may be cylindrical or prismatic. The cone-shaped structure 4182 may be a truncated cone or pyramid structure, the top surface of which is a flat pressing surface. A flat structure 4183 is formed at the connection point between the columnar structure 4181 and the conical structure 4182, and the flat structure 4183 surrounds the connection point between the columnar structure 4181 and the conical structure 4182. When the button cap is assembled to the bracket 420, the first protrusion 417 and the second protrusion 418 respectively penetrate the button ring 422, and the edge of the button ring 422 abuts against the flat structure. The conical structures 4182 of the first protrusion 417 and the second protrusion 418 extend into the button ring 422 and contact the pressed component on the circuit board after protruding from the button ring 422, thereby facilitating the pressing.
