Fig. 1-2 are schematic structural views of an automatic cleaning apparatus according to an exemplary embodiment, which may be a vacuum suction robot, a mopping/brushing robot, a window climbing robot, etc., as shown in fig. 1-2, and may include a mobile platform 100, a sensing system 120, a control system 130, a driving system 140, a cleaning module 150, an energy system 160, and a human-computer interaction system 170. Wherein:

the mobile platform 100 may be configured to automatically move along a target direction on the operation surface. The operating surface may be a surface to be cleaned by the automatic cleaning device. In some embodiments, the automatic cleaning device may be a floor mopping robot, and the automatic cleaning device works on the floor, which is the operation surface; the automatic cleaning equipment can also be a window cleaning robot, and works on the outer surface of the glass of the building, wherein the glass is the operation surface; the automatic cleaning device may also be a pipe cleaning robot, and the automatic cleaning device works on the inner surface of the pipe, which is the operation surface. Purely for the sake of illustration, the following description of the application will be given by way of example of a mopping robot.

In some embodiments, 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 according to unexpected environmental inputs; the autonomous mobile platform itself cannot adaptively make operational decisions based on unexpected environmental inputs, but may execute a given program or operate in accordance with certain logic. Accordingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be autonomously determined by the automatic cleaning apparatus; when the mobile platform 100 is an 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 includes a forward portion 111 and a rearward portion 110.

The perception system 120 includes a position determining device 121 located above the mobile platform 100, a buffer 122 located at the forward portion 111 of the mobile platform 100, cliff sensors 123 and ultrasonic sensors (not shown) located at the bottom of the mobile platform, infrared sensors (not shown), magnetometers (not shown), accelerometers (not shown), gyroscopes (not shown), odometers (not shown), and the like sensing devices, which provide various positional and motion state information of the machine to the control system 130.

In order to describe the behavior of the automatic cleaning device more clearly, the following directional definition is made: the robotic cleaning device may travel on the floor by various combinations of movements relative to three mutually perpendicular axes defined by the mobile platform 100: a transverse axis x, a front-rear axis y and a central vertical axis z. The forward driving direction along the front-rear axis y is denoted as "forward", and the backward driving direction along the front-rear axis y is denoted as "backward". The transverse axis x extends between the right and left wheels of the robotic cleaning device substantially along an axle center defined by the center point of the drive wheel assembly 141. Wherein the robotic cleaning device is rotatable about an x-axis. The rearward portion is "pitched up" when the forward portion of the automatic cleaning device is tilted up, and the rearward portion is "pitched down" when the forward portion of the automatic cleaning device is tilted down. In addition, the robotic cleaning device may rotate about the z-axis. In the forward direction of the robot cleaner, the robot cleaner is tilted to the right of the Y-axis as "turn right" and tilted to the left of the Y-axis as "turn left".

As shown in fig. 2, cliff sensors 123 are provided on the bottom of the moving platform 100 and in front of and behind the driving wheel assembly 141, and the cliff sensors 123 are used to prevent falling when the automatic cleaning apparatus is retreated, so that the automatic cleaning apparatus can be prevented from being damaged. The "front" mentioned above means the same side as the traveling direction of the robot cleaner, and the "rear" mentioned above means the opposite side as the traveling direction of the robot cleaner.

The position determining means 121 includes, but is not limited to, a camera, a laser ranging means (LDS Laser Direct Structuring).

The various components of the sensing system 120 may operate independently or in concert to more accurately achieve desired functionality. The cliff sensor 123 and the ultrasonic sensor are used for identifying the surface to be cleaned to determine the physical characteristics of the surface to be cleaned, including surface medium, cleaning degree and the like, and can be combined with a camera, a laser ranging device and the like for more accurate determination.

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

The forward portion 111 of the mobile platform 100 is provided with a bumper 122. The bumper 122 detects one or more events (or objects) in the path of travel of the robot via a sensor system, such as an infrared sensor, while the drive wheel assembly 141 advances the robot during cleaning, and the robot may be controlled to respond to the events (or objects), such as being remote from the obstacle, by the event (or object), such as an obstacle, wall surface, detected by the bumper 122.

The control system 130 is disposed on a circuit board in the mobile platform 100, and includes a non-transitory memory, such as a hard disk, a flash memory, a random access memory, a communication computing processor, such as a central processing unit, an application processor, and the application processor is configured to receive the sensed environmental information of the plurality of sensors transmitted from the sensing system 120, draw an instant map of the environment where the automatic cleaning device is located according to the obstacle information fed back by the laser ranging device, and the like, and autonomously determine a driving path according to the environmental information and the environmental map, and then control the driving system 140 to perform operations such as forward, backward, and/or steering according to the autonomously determined driving path. Further, the control system 130 may also determine whether to start the cleaning module 150 to perform the cleaning operation according to the environmental information and the environmental map.

Specifically, the control system 130 may combine the distance information and the speed information fed back by the buffer 122, the cliff sensor 123, the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer and other sensing devices to comprehensively determine what working state the sweeper is currently in, such as passing a threshold, going up a carpet, being located at the cliff, being blocked above or below, being full of dust box, being lifted up, and the like, and may further give a specific next action strategy according to different situations, so that the work of the automatic cleaning device better meets the requirements of the owner, and has better user experience. Furthermore, the control system can plan the most efficient and reasonable cleaning path and cleaning mode based on the instant map information drawn by SLAM, and greatly improves the cleaning efficiency of the automatic cleaning equipment.

The drive system 140 may execute drive commands to maneuver the robotic cleaning device across the floor based on specific distance and angle information, such as the x, y, and θ components. Fig. 3 and 4 are perspective and front views of one side drive wheel assembly 141 according to an embodiment of the present invention, wherein drive system 140 includes drive wheel assembly 141, and drive system 140 may control both left and right wheels simultaneously, and wherein drive system 140 preferably includes left and right drive wheel assemblies, respectively, for more precise control of machine motion. The left and right drive wheel assemblies are symmetrically disposed along a transverse axis defined by the mobile platform 100. The driving wheel assembly comprises a shell and a connecting frame, driving motors 146 are respectively arranged in the driving wheel assembly, the driving motors 146 are positioned at the outer sides of the driving wheel assembly 141, the axle center of each driving motor 146 is positioned in the section projection of the driving wheel assembly, and the driving wheel assembly 141 can be connected with a circuit for measuring driving current and an odometer.

In order for the robotic cleaning device to be able to move more stably or with greater motion capabilities on the floor, the robotic cleaning device may include one or more steering assemblies 142, which may be driven or driven, and in a configuration including, but not limited to, universal wheels, the steering assemblies 142 may be positioned in front of the drive wheel assemblies 141.

The drive motor 146 powers rotation of the drive wheel assembly 141 and/or the steering assembly 142.

The drive wheel assembly 141 may be removably attached to the mobile platform 100 for ease of disassembly and maintenance. The drive wheel may have an offset drop-down suspension system movably fastened, e.g. rotatably attached, to the robot moving platform 100 and maintained in contact and traction with the floor with a certain contact force by means of a resilient element 143, such as a tension spring or a compression spring, while the cleaning module 150 of the robot also contacts the surface to be cleaned with a certain pressure.

The energy system 160 includes rechargeable batteries, such as nickel metal hydride batteries and lithium batteries. The rechargeable battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit and a battery under-voltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit and the battery under-voltage monitoring circuit are connected with the singlechip control circuit. The host computer charges through setting up the charging electrode in fuselage side or below and charging pile connection. If dust is attached to the exposed charging electrode, the plastic body around the electrode is melted and deformed due to the accumulation effect of the electric charge in the charging process, and even the electrode itself is deformed, so that normal charging cannot be continued.

The man-machine interaction system 170 includes keys on the host panel for the user to select functions; the system also comprises a display screen and/or an indicator light and/or a loudspeaker, wherein the display screen, the indicator light and the loudspeaker show the current state or function selection item of the machine to a user; a cell phone client program may also be included. For the path navigation type cleaning equipment, a map of the environment where the equipment is located and the position where the machine is located can be displayed to a user at the mobile phone client, and more abundant and humanized functional items can be provided for the user.

The cleaning module 150 may include a dry cleaning module 151 and/or a wet cleaning module 400.

As shown in fig. 5 to 8, the dry cleaning module 151 includes a rolling brush, a dust box, a blower, and an air outlet. The rolling brush with certain interference with the ground sweeps up the garbage on the ground and winds up the garbage in front of the dust collection opening between the rolling brush and the dust box, and then the dust box is sucked by the suction gas generated by the fan and passing through the dust box. The dust removal capability of the sweeper can be characterized by the sweeping efficiency DPU (Dust pickup efficiency) of the garbage, the sweeping efficiency DPU is influenced by the structure and the material of the rolling brush, the wind power utilization rate of an air duct formed by a dust collection port, a dust box, a fan, an air outlet and connecting parts among the four components is influenced, and the type and the power of the fan are influenced, so that the sweeper is a complex system design problem. The improvement in dust removal capability is of greater significance for energy-limited cleaning automatic cleaning equipment than for conventional plug-in cleaners. Because the dust removal capability is improved, the energy requirement is directly and effectively reduced, that is to say, the original machine which can clean the ground of 80 square meters after charging once can be evolved into the machine which can clean the ground of 180 square meters or more after charging once. And the service life of the battery, which reduces the number of times of charging, is greatly increased, so that the frequency of replacing the battery by a user is also increased. More intuitively and importantly, the improvement of dust removal capability is the most obvious and important user experience, and users can directly draw a conclusion on whether the dust is cleaned/rubbed clean. The dry cleaning module may also include an edge brush 157 having a rotational axis that is angled relative to the floor for moving debris into the roller brush area of the cleaning module 150.

Fig. 5 is a schematic structural view of the dust box 152 in the dry cleaning module, fig. 6 is a schematic structural view of the blower 156 in the dry cleaning module, fig. 7 is a schematic open state of the dust box 152, and fig. 8 is a schematic assembled state of the dust box and the blower.

The rolling brush with certain interference with the ground sweeps up the garbage on the ground and winds up the dust collection opening 154 between the rolling brush and the dust box 152, then the dust box 152 is sucked by the air blower 156, the dust is isolated by the filter screen 153 at one side of the dust box 152 near the dust collection opening 154, the filter screen 153 completely isolates the dust collection opening from the air outlet, and the filtered air enters the air blower 156 through the air outlet 155.

Typically, the dust suction port 154 of the dust box 152 is located in front of the machine, the air outlet 155 is located at the side of the dust box 152, and the air suction port of the fan 156 is butted with the air outlet of the dust box.

The front panel of the dust box 152 may be opened for cleaning the dust box 152 of the trash.

The filter screen 153 is detachably connected with the box body of the dust box 152, so that the filter screen is convenient to detach and clean.

As shown in fig. 9-11, the wet cleaning module 400 provided by the present invention is configured to clean at least a portion of the operation surface by wet cleaning; wherein the wet cleaning module 400 includes: the cleaning device comprises a cleaning head 410 and a driving unit 420, wherein the cleaning head 410 is used for cleaning at least one part of the operation surface, and the driving unit 420 is used for driving the cleaning head 410 to reciprocate along a target surface, and the target surface is one part of the operation surface. The cleaning head 410 reciprocates along the surface to be cleaned, and the contact surface between the cleaning head 410 and the surface to be cleaned is provided with cleaning cloth or a cleaning plate, and high-frequency friction is generated between the cleaning head and the surface to be cleaned through the reciprocation, so that stains on the surface to be cleaned are removed. The reciprocating motion may be repeated motion along any one or more directions in the operation surface, or may be vibration perpendicular to the operation surface, which is not limited strictly.

As shown in fig. 9, the driving unit 420 includes: a driving platform 421 connected to the bottom surface of the mobile platform 100, for providing driving force; the support platform 422 is detachably connected to the driving platform 421, and is used for supporting the cleaning head 410, and can be lifted under the driving of the driving platform 421.

The lifting module is disposed between the cleaning module 150 and the mobile platform 100, and is used for enabling the cleaning module 150 to better contact with the surface to be cleaned, or adopting different cleaning strategies for the surface to be cleaned with different materials.

The dry cleaning module 151 may be connected to the mobile platform 100 through a passive lifting module, and when the cleaning apparatus encounters an obstacle, the dry cleaning module 151 may more conveniently cross the obstacle through the lifting module.

The wet cleaning module 400 may be connected to the mobile platform 100 through an active lifting module, and when the wet cleaning module 400 temporarily does not participate in the work or encounters a surface to be cleaned, which cannot be cleaned by the wet cleaning module 400, the wet cleaning module 400 is lifted up through the active lifting module and separated from the surface to be cleaned, thereby realizing the change of the cleaning means.

As shown in fig. 10 to 11, the driving platform 421 includes: a motor 4211 disposed on a side of the driving platform 421 near the moving platform 100, and outputting power through a motor output shaft; a driving wheel 4212 connected to the output shaft of the motor, wherein the driving wheel 4212 has an asymmetric structure; the vibration member 4213 is disposed on the opposite side of the driving platform 421 from the motor 4211, and is connected to the driving wheel 4212, and performs a reciprocating motion under an asymmetric rotation of the driving wheel 4212.

The drive platform 421 may further include drive wheels and a gear mechanism. The gear mechanism 235 may connect the motor 4211 and the drive wheel 4212. The motor 4211 may directly drive the driving wheel 4212 to perform a rotation motion, or may indirectly drive the driving wheel 4212 to perform a rotation motion through a gear mechanism. One of ordinary skill in the art will appreciate that the gear mechanism may be a single gear or a plurality of gear sets.

The motor 4211 simultaneously transmits power to the cleaning head 410, the driving platform 421, the supporting platform 422, the water feeding mechanism, the water tank, etc. through the power transmission means. The energy system 160 provides power and energy to the motor 4211 and is controlled overall by the control system 130. The power transmission device can be a gear transmission, a chain transmission, a belt transmission, a worm gear and the like.

The motor 4211 comprises a forward output mode and a reverse output mode, wherein the motor 4211 rotates forward in the forward output mode, the motor 4211 rotates reversely in the reverse output mode, and in the forward output mode of the motor 4211, the motor 4211 can drive the cleaning head 410 and the water delivery mechanism in the wet cleaning assembly 400 to synchronously move through the power transmission device.

Further, the driving platform 421 further includes: the connecting rod 4214 extends along the edge of the driving platform 421, and connects the driving wheel 4212 with the vibration member 4213, so that the vibration member 4213 extends to a preset position, where the extending direction of the vibration member 4213 is perpendicular to the connecting rod 4214.

The motor 4211 is connected to the driving wheel 4212, the vibration member 4213, the connecting rod 4214, and the vibration damper 4215 via a power transmission device. When the wet cleaning assembly 400 is started, the motor 4211 starts to rotate forward, the motor 4211 drives the connecting rod 4214 to reciprocate along the surface of the driving platform 421 through the driving wheel 4212, and meanwhile, the vibration buffer device 4215 drives the vibration member 4213 to reciprocate along the surface of the driving platform 421, the vibration member 4213 drives the cleaning substrate 4221 to reciprocate along the surface of the supporting platform 422, and the cleaning substrate 4221 drives the movable region 412 to reciprocate along the surface to be cleaned. At this time, the clean water pump discharges clean water from the clean water tank and sprays the clean water on the cleaning head 410 through the water discharge device 4217, and the cleaning head 410 cleans the surface to be cleaned by reciprocating motion.

The cleaning intensity/efficiency of the robotic cleaning device may also be automatically and dynamically adjusted based on the operating environment of the robotic cleaning device. Such as an automated cleaning device, may be dynamically adjusted based on physical information sensed by sensing system 120 on the surface to be cleaned. For example, the sensing system 120 may detect information about the flatness of the surface to be cleaned, the material of the surface to be cleaned, whether there is oil or dirt, etc., and communicate such information to the control system 130 of the automatic cleaning apparatus. Accordingly, the control system 130 may direct the automatic cleaning apparatus to automatically and dynamically adjust the rotation speed of the motor and the transmission ratio of the power transmission device according to the working environment of the automatic cleaning apparatus, thereby adjusting the preset reciprocation period of the reciprocation of the cleaning head 410.

For example, when the automatic cleaning apparatus is operated on a flat floor, the preset reciprocation period may be automatically and dynamically adjusted to be longer, and the water amount of the water pump may be automatically and dynamically adjusted to be smaller; when the automatic cleaning device works on a less flat ground, the preset reciprocation period can be automatically and dynamically adjusted to be shorter, and the water quantity of the water pump can be automatically and dynamically adjusted to be larger. This is because planar floors are easier to clean relative to less planar floors, and thus cleaning uneven floors requires faster reciprocation (i.e., higher frequency) of the cleaning head 410 and a greater amount of water.

For another example, when the automatic cleaning device works on a table top, the preset reciprocation period can be automatically and dynamically adjusted to be longer, and the water quantity of the water pump can be automatically and dynamically adjusted to be smaller; when the automatic cleaning apparatus 100 is operating on the floor, the preset reciprocation period may be automatically and dynamically adjusted to be short and the water amount of the water pump may be automatically and dynamically adjusted to be large. This is because the table top is less dusty and greasy than the floor, and the material comprising the table top is easier to clean, so that the cleaning head 410 is required to perform a smaller number of reciprocating movements, and the water pump provides a relatively smaller amount of water to clean the table top.

The support platform 422 includes: the cleaning base plate 4221 is movably disposed on the support platform 422, and the cleaning base plate 4221 reciprocates under the vibration of the vibration member 4213. Optionally, the cleaning substrate 4221 comprises: an assembly notch (not shown) is disposed at a position contacting the vibration member 4213, and when the support platform 422 is connected to the driving platform 421, the vibration member 4213 is assembled to the assembly notch, so that the cleaning substrate 4221 can reciprocate synchronously with the vibration member 4213.

Figure 12 illustrates another slider-crank based cleaning head drive mechanism 800 in accordance with various embodiments of the present application. The drive mechanism 800 may be applied to the drive platform 421. The driving mechanism 800 includes a driving wheel 4212, a vibrating member 4213, a cleaning base 4221, a chute 4222 (first chute), and a chute 4223 (second chute).

The slide grooves 4222, 4223 are open on the support platform 422. Both ends of the cleaning substrate 4221 include a slider 525 (first slider) and a slider 528 (second slider), respectively. The sliders 525 and 528 are each a protrusion at both ends of the cleaning substrate 4221. The slider 525 is inserted into the slide groove 4222 and can slide along the slide groove 4222; the slider 528 is inserted into the slide groove 4223 and can slide along the slide groove 4223. In some embodiments, the chute 4222 is collinear with the chute 4223. In some embodiments, the chute 4222 and the chute 4223 are not collinear. In some embodiments, the chute 4222 extends in the same direction as the chute 4223. In some embodiments, the direction of extension of the chute 4222 and the chute 4223 is the same as the direction of extension of the cleaning substrate 4221. In some embodiments, the direction of extension of the chute 4222 and the chute 4223 is different from the direction of extension of the cleaning substrate 4221. In some embodiments, the direction of extension of the chute 4222 is different from the chute 4223. For example, as shown in fig. 12, the extending direction of the chute 4222 is the same as the extending direction of the cleaning substrate 4221, and the extending direction of the chute 4223 is at an angle to the extending direction of the chute 4222.

The vibration member 4213 comprises a swivel end 512 and a slide end 514. The swivel end 512 is coupled to the drive wheel 4212 by a first pivot 516 and the slide end 514 is coupled to the cleaning base 4221 by a second pivot 518.

The center of rotation of the drive wheel 4212 is point O, and the center of rotation of the first pivot 516 is point a. The O point and the A point are not coincident, and the distance between the O point and the A point is a preset distance d.

When the driving wheel 4212 rotates, the point a rotates in a circular manner. Accordingly, the rotary end 512 follows the point a for circular rotary motion; the sliding end 514 drives the cleaning substrate 4221 to slide through the second pivot 518. Accordingly, the slider 525 of the cleaning substrate 4221 makes a reciprocating linear motion along the chute 4222; the slider 528 reciprocates linearly along the chute 4223. In fig. 4, the moving speed of the moving platform 210 is V0, and the moving direction is the target direction. According to some embodiments, when the chute 4223 and the chute 4222 are respectively approximately perpendicular to the direction of the moving speed V0 of the moving platform 210, the overall displacement of the cleaning substrate 4221 is substantially perpendicular to the target direction. According to other embodiments, when either one of the runner 4223 and the runner 4222 is at an angle other than 90 degrees from the target direction, the overall displacement of the cleaning substrate 4221 includes both components perpendicular to the target direction and parallel to the target direction.

Further, a vibration buffer device 4215 is disposed on the connecting rod 4214, for reducing vibration in a specific direction, and in this embodiment, for reducing vibration in a moving component direction perpendicular to the target direction of the automatic cleaning device.

Figure 13 illustrates another dual crank mechanism based cleaning head drive mechanism 600 in accordance with various embodiments of the present application. The drive mechanism 600 may be applied to the drive platform 421. The driving mechanism 600 includes a driving wheel 4212 (first driving wheel), a driving wheel 4212' (second driving wheel), and a cleaning substrate 4221.

The cleaning substrate 4221 has two ends. The first end is connected to the drive wheel 4212 by a pivot 624 (first pivot); the second end is connected to the drive wheel 4212' by a pivot 626 (second pivot). The center of rotation of the drive wheel 4212 is point O, and the center of rotation of the pivot 624 is point a. The O point and the A point are not coincident, and the distance between the O point and the A point is a preset distance d. The center of rotation of the drive wheel 236 is at point O 'and the center of rotation of the pivot 626 is at point a'. The O 'point and the A' point are not coincident, and the distance between the O 'point and the A' point is a preset distance d. In some embodiments, points a, a ', O, and O' are located on the same plane. Thus, the driving wheels 4212, 4212', and the cleaning base plate 4221 may form a double crank mechanism (or parallelogram mechanism), wherein the cleaning base plate 4221 serves as a coupling rod, and the driving wheels 4212 and 4212' serve as two cranks.

Fig. 14 illustrates a slider-crank based drive mechanism 700 in accordance with various embodiments of the present application. The drive mechanism 700 may be applied to the drive platform 421. The drive mechanism 700 includes a drive wheel 4212, a cleaning base plate 4221, and a chute 4222.

The chute 4222 opens onto the support platform 422. The cleaning substrate 4221 includes a swivel end 4227 and a slide end 4226.

The O point and the A point are not coincident, and the distance between the O point and the A point is a preset distance d. The slide end 4226 comprises a slide 4225. The slider 4225 is a protrusion on the sliding end 4226. A slider 4225 is inserted into the chute 4222 and is slidable along the chute 4222. Thus, the driving wheel 4221, the cleaning base plate 4221, and the slider 4225 and the chute 4222 constitute a crank slider mechanism.

When the driving wheel 4212 rotates, the point a makes a circular rotation motion. Accordingly, the rotation end 4227 of the cleaning substrate 4221 performs circular rotation movement following the point a; the slider 4225 slides in the chute 4222 to reciprocate linearly. As a result, the cleaning substrate 4221 starts to reciprocate. According to some embodiments, the chute 4222 approximates a direction perpendicular to the target direction of the movement speed of the moving platform, and thus, the linear movement of the sliding end 4226 includes a component perpendicular to the target direction, and the circular swiveling movement of the swiveling end 4227 includes both a component perpendicular to the target direction and a component parallel to the target direction.

In fig. 14, the moving speed of the moving platform is V0, and the moving direction is the target direction; while chute 4222 is approximately perpendicular to the target direction. At this time, the reciprocating motion of the cleaning substrate 4221 as a whole has both a movement component parallel to the target direction of the robot cleaner and a movement component perpendicular to the target direction of the robot cleaner.

Further, the cleaning head 410 further includes: and a flexible connection part 413 disposed between the fixed area 411 and the movable area 412, for connecting the fixed area 411 and the movable area 412. The cleaning head 410 further includes: a sliding buckle 414 extends along the edge of the cleaning head 410 and is detachably mounted at a clamping position 4225 of the supporting platform 422.

As shown in fig. 9, the cleaning head 410 may be made of a material having a certain elasticity, and the cleaning head 410 is fixed to the surface of the support platform 422 by an adhesive layer, thereby achieving a reciprocating motion. The cleaning head 410 is always in contact with the surface to be cleaned when the cleaning head 410 is in operation.

The first connection end 501 and the second connection end 502 are respectively located at two sides of the wet cleaning module 400, and stably provide a lifting force to raise or lower the wet cleaning module 400.

Specifically, the first connection end 501 includes a first bracket 5011 fixedly connected to the bottom of the mobile platform 100; the first bracket 5011 is generally a "figure" shaped structure, the first bracket 5011 comprising: the tail ends of the cross beam 50111, the first longitudinal beam 50114 and the second longitudinal beam 50115, the first longitudinal beam 50114 and the second longitudinal beam 50115 are respectively fixedly connected to the mobile platform 100 through bolts, so as to provide supporting force when the wet cleaning module 400 is lifted.

The first connection end 501 further includes a first connection rod pair 5012, one end of the first connection rod pair 5012 is rotatably connected to the first bracket 5011, and the other end is rotatably connected to the wet cleaning module 400. The first connecting rod pair 5012 can be in a hollow structure, so that the overall weight of the lifting end can be reduced.

Optionally, the first connecting rod pair 5012 includes a first connecting rod 50121 and a second connecting rod 50122 that are disposed in parallel, first ends of the first connecting rod 50121 and the second connecting rod 50122 are rotatably connected to the first longitudinal beam 50114 through a movable stud, and second ends of the first connecting rod 50121 and the second connecting rod 50122 are rotatably connected to the wet cleaning module 400 through a movable stud. For example, two ends of the first connecting rod 50121 and the second connecting rod 50122 are respectively provided with a through hole with a diameter larger than that of the movable stud, so that the movable stud can freely rotate in the through hole, and the movable stud is fixedly connected to the first longitudinal beam 50114 after passing through the through hole. When the motor 4211 provides tension to the first end via the cable, the first ends of the first connecting rod 50121 and the second connecting rod 50122 simultaneously rotate around the movable stud at the first end, and the second end rises under the tension of the cable, so that the wet cleaning module 400 rises. When the motor 4211 releases the pulling force to the first end through the pull cable, the first ends of the first connecting rod 50121 and the second connecting rod 50122 simultaneously rotate reversely around the movable stud at the first end, and the second end descends under the action of gravity, so that the wet cleaning module 400 descends.

The lifting structure 500 further includes a pull cable 42194 for providing a lifting force to rotate the first connecting rod pair 5012 within a predetermined angle. The cable 42194 includes: and a cable motor terminal 50131 connected with the driving unit 420, for example, a gear winding connection connected with an output shaft of the motor, and realizing telescopic movement under the rotation of the motor. The cable bracket terminal 50132 is connected to the first bracket 5011, and the motor lifts or sinks the second ends of the first and second connection bars 50121 and 50122 by the cable 42194.

Optionally, the first bracket 5011 further includes: spout 50112, along crossbeam 50111 surface extends, and, card hole 50113 runs through crossbeam 50111 set up in spout 50112 extends the end, is used for accomodating and the buckle cable support terminal 50132, guy cable 42194 passes through spout 50112 and card hole 50113 with the first end of head rod 50121 and second connecting rod 50122 is connected, and the direction of movement of cable can be restricted to spout 50112, guarantees the stability of module lift, and the width of spout matches with the thickness of cable and is advisable.

As shown in fig. 17, the second connection terminal 502 includes: the second bracket 5021 is fixedly connected to the bottom of the mobile platform 100; a second connection rod pair 5022, one end of which is rotatably connected to the second bracket 5021 and the other end of which is rotatably connected to the wet cleaning module 400; the second connection rod pair 5022 rotates with the rotation of the first connection rod pair 5012. The second connecting rod pair 5022 can be of a hollow structure, and the overall weight of the lifting end can be reduced.

Specifically, the second connection rod pair 5022 includes a third connection rod 50221 and a fourth connection rod 50222 that are arranged in parallel, first ends of the third connection rod 50221 and the fourth connection rod 50222 are rotatably connected to the second bracket 5021 through movable studs, and second ends of the third connection rod 50221 and the fourth connection rod 50222 are rotatably connected to the wet cleaning module 400 through movable studs. For example, through holes with diameters larger than the diameters of the movable studs are respectively formed at two ends of the third connecting rod 50221 and the fourth connecting rod 50222, so that the movable studs can freely rotate in the through holes, and the movable studs pass through the through holes and are fixedly connected to the second bracket 5021 and the wet cleaning module 400. When the first connection end 501 is driven by the motor 4211 to rotate, the first ends of the third connection rod 50221 and the fourth connection rod 50222 simultaneously rotate around the movable stud of the first end, and the second ends of the third connection rod 50221 and the fourth connection rod 50222 simultaneously rotate around the movable stud of the second end, so that the wet cleaning module 400 is lifted. When the first connection end 501 releases the pulling force, the third connection rod 50221 and the fourth connection rod 50222 simultaneously rotate reversely around the movable stud, and descend under the action of gravity, so that the wet cleaning module 400 sinks.

Through the four-bar lifting structure arranged between the wet cleaning module and the movable platform, the wet cleaning module can be lifted relative to the movable platform, the wet cleaning module is lowered to enable the wet cleaning module to be in contact with the ground when the mopping task is executed, and the wet cleaning module is lifted to enable the wet cleaning module to be separated from the ground when the mopping task is executed, so that the increase of resistance caused by the existence of the cleaning module when the cleaning equipment freely moves on the cleaned surface is avoided.

The lifting module can carry out cleaning operation on the wet cleaning module according to different surfaces to be cleaned by matching with the surface type sensor such as the surface medium sensor 103 and the like, for example, the wet cleaning module is lifted on the surface of a carpet, and the wet cleaning module is put down on the surface of a floor/ground tile and the like for cleaning, so that a more comprehensive cleaning effect is realized.

For existing automatic cleaning devices without surface media sensors, carpet media are generally considered to be obstacles only, which can be avoided when cleaning the floor. However, for an automatic cleaning device equipped with a surface media sensor 103, carpet areas may be detected and even carpet cleaning may be required, at which time obtaining a fine map of the carpet area may provide assistance to the automatic cleaning device in cleaning the carpet.

Based on this, exemplary embodiments of the present disclosure provide a mapping method, referring to fig. 19, which may include the steps of:

step S2010, scanning the boundary of the surface medium area to generate an initialization area;

step S2020, merging boundary coordinates of the initialization area to obtain a merged area;

step S2030, splitting the merging area into a plurality of sub-areas according to a preset shape, and drawing a surface medium area boundary according to the sub-areas and the merging area, so as to obtain a surface medium area map.

According to the map drawing method provided by the exemplary embodiment of the disclosure, the boundary of the surface medium area is scanned, the initialization area is generated, the smoother merging area can be obtained according to the initialization area, and the boundary of the surface medium area can be drawn by combining the sub-area and the merging area, so that the surface medium area map can be drawn, the obtained boundary of the surface medium area map is smooth, the surface medium area map is more accurate, and the cleaning and positioning of the surface medium area or the edge area of the surface medium area can be facilitated for the automatic cleaning equipment.

It should be noted that the mapping method not only can be used for mapping a single surface medium area, but also can be used for mapping a second surface medium area located in a first surface medium area, where the first surface medium is one or more of floor surface mediums such as a wooden floor, a carpet, a tile, a cement surface, and the like; the second surface medium is one or more of a wood floor, carpet, tile, cement surface, etc., floor surface medium that is different from the first surface medium.

The position of the second surface media area is recorded when the robot cleaning device cleans within the first surface media area, for example, when the robot cleaning device cleans along a wall, when the surface media sensor 103 of the robot cleaning device detects the second surface media area. The robotic cleaning device then enters the surface medium area mapping module to map the second surface medium area for later reference.

In an exemplary embodiment of the present disclosure, scanning the boundary of the surface media region to map the surface media region includes: the boundary of the surface dielectric region is scanned to generate an initialization region.

In exemplary embodiments of the present disclosure, a boundary of a surface medium region may be scanned using a surface medium region identification device (e.g., a surface medium sensor that can identify a surface medium), such as a carpet region. After the scanning, an initialization area 2100 as shown in fig. 20 may be produced according to the scanned boundary, and the initialization area 2100 may also be recorded in the automatic cleaning device.

Next, the boundary coordinates of the initialization area 2100 may be merged, for example, two or more adjacent boundary coordinates may be merged into one coordinate, and specifically, an average value coordinate of two or more adjacent boundary coordinates may be taken as the boundary coordinates of the merged area, to obtain a merged area 2200 smoother than the boundary of the initialization area 2100 as shown in fig. 21. Meanwhile, the merge area 2200 may also be stored in the automatic cleaning apparatus for reference in a subsequent cleaning.

In the exemplary embodiment of the present disclosure, after the merging area 2200 is obtained, it is also necessary to split the merging area 2200 according to a preset shape to form a plurality of sub-areas 2301, 2302, and store the plurality of sub-areas 2301, 2302, etc. in an automatic cleaning device, and in a subsequent cleaning process, local sub-area cleaning may be performed as needed.

However, in the exemplary embodiment of the present disclosure, after obtaining the plurality of sub-areas, it is further necessary to smooth each sub-area according to a preset shape to obtain an edge-beautified surface medium area map.

In practical applications, the minimum unit that can be identified by the robotic cleaning device during scanning of the boundary of the surface media area is the coordinates of points that will enclose an initialization area, i.e., the initialization area is made up of a plurality of initial boundary coordinates. Likewise, the merge area is also composed of a plurality of merge boundary coordinates.

In the exemplary embodiment of the disclosure, in the process of smoothing each sub-area, the merging boundary coordinates of the sub-area outside the sub-area near the sub-area may be deleted, for example, the redundant merging boundary coordinate points 2303 in fig. 22 may be deleted, so that redundant coordinate data may be removed, so that the drawn surface medium area map is closer to a conventional shape such as a preset shape, an unconventional map such as a tapered graph with a more sharp boundary is avoided, the accuracy of the drawn surface medium area map is improved, and a more accurate reference is provided for the subsequent cleaning of the automatic cleaning device. Fig. 23 illustrates an example of a surface medium area map 2400 drawn by a mapping method provided according to an exemplary embodiment of the present disclosure.

Here, the merging boundary coordinates outside the sub-region and near the sub-region refer to merging boundary coordinates outside all sub-regions. And when determining the merging boundary coordinates of the sub-region outside and approaching the sub-region, the merging boundary coordinates may be determined according to the shortest length from the sub-region boundary, for example, when the shortest length from one merging boundary coordinate to the sub-region boundary, that is, the length between the merging boundary coordinates and the nearest sub-region boundary is smaller than the preset length, the merging boundary coordinates are determined as the merging boundary coordinates of the sub-region outside and approaching the sub-region.

In practical applications, the size of the preset length may be set according to practical situations, for example, determined according to the size of the sub-area, which is not particularly limited in the present exemplary embodiment.

In the exemplary embodiment of the disclosure, after deleting the merging boundary coordinates of the sub-region outside the sub-region and close to the sub-region, the remaining merging boundary coordinates may be sequentially connected by lines to draw a smoother surface medium region boundary, thereby providing a basis for obtaining a surface medium region map with beautified edges.

After the surface medium region boundary is drawn, it is also necessary to fill the surface medium region boundary with surface medium marks to obtain a surface medium region map. Wherein the surface medium mark can be a color mark, i.e. the inside of the boundary of the surface medium area is filled with a color different from that of other surface medium areas to show distinction; alternatively, the surface media marking may be a machine-distinguishable marking of other robotic cleaning devices or the like, to which the exemplary embodiments of the present disclosure are not particularly limited.

In practical applications, the preset shape may be square, circular, or other shapes such as diamond, as shown in fig. 22, the sub-region 2301 determined according to the preset shape is a square region, and the sub-region 2302 is a circular region. The exemplary embodiments of the present disclosure are not particularly limited to a specific preset shape.

After the surface medium area map is obtained, the surface medium area can be stored in a memory of the automatic cleaning equipment, and then the surface medium area is communicated with the stored room map through the automatic cleaning equipment and is sent to the user terminal, so that a user can conveniently view the room map with the surface medium area map, and convenience is brought to later control operation of the user.

In practical applications, the automatic cleaning device further includes other functions that help to implement overall operation, which will not be described in detail in this exemplary embodiment.

Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform, etc.

In an exemplary embodiment of the present disclosure, there is also provided a mapping apparatus provided to an automatic cleaning device including a surface medium sensor, as shown in fig. 24, the mapping apparatus 2500 may include: a boundary scan module 2501, a region merge module 2502, and a map drawing module 2503, wherein:
