Fig. 1-2 are schematic structural views illustrating an automatic cleaning apparatus according to an exemplary embodiment, which may be a vacuum suction robot, a mopping/brushing robot, a window climbing robot, or the like, as shown in fig. 1-2, and may include a mobile platform 100, a sensing system 120, a control system 130, a drive 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 of the automatic cleaning device. In some embodiments, the robotic cleaning device may be a floor-mopping robot, and the robotic cleaning device operates on a floor surface, the floor surface being the operating surface; the automatic cleaning equipment can also be a window cleaning robot, and the automatic cleaning equipment works on the outer surface of the glass of the building, wherein the glass is the operation surface; the automatic cleaning device can also be a pipeline cleaning robot, and the automatic cleaning device works on the inner surface of the pipeline, wherein the inner surface of the pipeline is the operation surface. The following description in this application is given by way of example of a floor-mopping robot, purely for illustration purposes.

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 operation decisions according to unexpected environmental inputs; the non-autonomous mobile platform itself cannot adaptively make operational decisions based on unexpected environmental inputs, but may execute established programs or operate according to certain logic. Accordingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be autonomously determined by the robotic cleaning device; when the mobile platform 100 is a non-autonomous mobile platform, the target direction may be set systematically 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 sensing 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, a cliff sensor 123 and an ultrasonic sensor (not shown), an infrared sensor (not shown), a magnetometer (not shown), an accelerometer (not shown), a gyroscope (not shown), an odometer (not shown), and other sensing devices located at the bottom of the mobile platform, and provides various position information and motion state information of the machine to the control system 130.

To describe the behavior of the automatic cleaning device more clearly, the following directional definitions are made: the robotic cleaning device can travel over the floor through various combinations of movement relative to the following three mutually perpendicular axes defined by the mobile platform 100: a transverse axis Y, a front-to-back axis X, and a central vertical axis Z. The forward driving direction along the forward-rearward axis X is denoted as "forward", and the rearward driving direction along the forward-rearward axis X is denoted as "rearward". The transverse axis Y extends substantially along the axis defined by the center point of the drive wheel assembly 141 between the right and left wheels of the robotic cleaning device. Wherein the robotic cleaning device is rotatable about a Y-axis. "pitch up" when the forward portion of the robotic cleaning device is tilted upward and the rearward portion is tilted downward, and "pitch down" when the forward portion of the robotic cleaning device is tilted downward and the rearward portion is tilted upward. Additionally, the robotic cleaning device may be rotatable about the Z-axis. In the forward direction of the automatic cleaning apparatus, when the automatic cleaning apparatus is tilted to the right side of the X axis, it turns to the right, and when the automatic cleaning apparatus is tilted to the left side of the X axis, it turns to the left.

As shown in fig. 2, cliff sensors 123 for preventing the automatic cleaning apparatus from falling when the automatic cleaning apparatus is retreated are provided on the bottom of the moving platform 100 and in front of and behind the driving wheel assemblies 141, so that the automatic cleaning apparatus can be prevented from being damaged. The foregoing "front" refers to the same side with respect to the traveling direction of the automatic cleaning apparatus, and the foregoing "rear" refers to the opposite side with respect to the traveling direction of the automatic cleaning apparatus.

Specific types of position determining devices 121 include, but are not limited to, cameras, laser distance measuring devices (LDS).

The various components of the sensing system 120 may operate independently or together to achieve a more accurate function. The cliff sensor 123 and the ultrasonic sensor are used for identifying the surface to be cleaned so as to determine the physical characteristics of the surface to be cleaned, including the surface material, the cleaning degree and the like, and can be combined with a camera, a laser ranging device and the like for more accurate judgment.

For example, it may be determined whether the surface to be cleaned is a carpet by the ultrasonic sensor, and if the ultrasonic sensor determines that the surface to be cleaned is a carpet material, 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 travel path of the robotic cleaning device via a sensor system, such as an infrared sensor, as the robotic cleaning device is propelled across the floor by the drive wheel assembly 141 during cleaning, and the robotic cleaning device can respond to the events (or objects), such as an obstacle, a wall, by controlling the drive wheel assembly 141 to cause the robotic cleaning device to respond to the events (or objects), such as a distance from the obstacle, as 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 sensed environmental information of the plurality of sensors transmitted from the sensing system 120, draw an instantaneous map of the environment in which the automatic cleaning apparatus is located using a positioning algorithm, such as SLAM, based on obstacle information fed back from the position determination device, and the like, and autonomously determine a travel path based on the environmental information and the environmental map, and then control the driving system 140 to perform operations, such as forward, backward, and/or steering, based on the autonomously determined travel path. Further, the control system 130 can also determine whether to start the cleaning module 150 for cleaning operation according to the environmental information and the environmental map.

Specifically, the control system 130 may comprehensively determine what working state the sweeper is currently in by combining 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, for example, when the distance information and the speed information are passed through a threshold, the sweeper is located at the cliff, the upper carpet or the lower carpet is stuck, the dust box is full, the sweeper is taken up and the like, and further, a specific next-step action strategy is given according to different conditions, so that the work of the automatic cleaning device better meets the requirements of an owner, and better user experience is achieved. Furthermore, the control system can plan the most efficient and reasonable cleaning path and cleaning mode based on the instant map information drawn by the SLAM, and the cleaning efficiency of the automatic cleaning equipment is greatly improved.

Drive system 140 may execute drive commands to steer the robotic cleaning device across the floor based on specific distance and angle information, such as x, y, and theta components. As shown in fig. 2, drive system 140 includes a drive wheel assembly 141, and drive system 140 may control both the left and right wheels, preferably drive system 140 includes a left drive wheel assembly and a right drive wheel assembly, respectively, for more precise control of machine motion. The left and right drive wheel assemblies are symmetrically disposed along a lateral axis defined by the mobile platform 100.

In order to provide the automatic cleaning device with more stable movement or enhanced movement capability over the floor surface, the automatic cleaning device may include one or more steering assemblies 142, the steering assemblies 142 may be driven wheels or driving wheels, and the steering assemblies 142 may be configured to include, but are not limited to, universal wheels, and the steering assemblies 142 may be positioned in front of the driving wheel assemblies 141.

Energy source system 160 includes rechargeable batteries such as nickel metal hydride batteries and lithium batteries. The charging 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 single chip microcomputer control circuit. The host computer is connected with the charging pile through the charging electrode arranged on the side or the lower part of the machine body for charging.

The human-computer interaction system 170 comprises keys on a panel of the host computer, and the keys are used for a user to select functions; the machine control system can further comprise 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; and a mobile phone client program can be further included. For the path navigation type cleaning equipment, a map of the environment where the equipment is located and the position of a machine can be displayed for a user at a mobile phone client, and richer and more humanized function items can be provided for the user.

As shown in fig. 2, the cleaning module 150 may include a dry cleaning module 151.

The dry cleaning module 151 includes a roller brush, a dust box, a blower, and an air outlet. The rolling brush with certain interference with the ground sweeps the garbage on the ground and winds the garbage to the front of a dust suction opening between the rolling brush and the dust box, and then the garbage is sucked into the dust box by air which is generated by the fan and passes through the dust box and has suction force. The dust removal capability of the sweeper can be represented by the sweeping efficiency DPU (dust pick up efficiency), which 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 suction port, a dust box, a fan, an air outlet and connecting parts among the dust suction port, the dust box, the fan, the air outlet and the dust box, the type and the power of the fan, and the sweeper is a complicated system design problem. Compared with the common plug-in dust collector, the improvement of the dust removal capability is more significant for cleaning automatic cleaning equipment with limited energy. Because the improvement of the dust removal capability directly and effectively reduces the energy requirement, namely the machine which can clean the ground of 80 square meters by charging once can be developed into the machine which can clean 180 square meters or more by charging once. And the service life of the battery with reduced charging times is greatly increased, so that the frequency of replacing the battery by a user is reduced. More intuitively and importantly, the improvement of the dust removal capability is the most obvious and important user experience, and the user can directly draw a conclusion whether the sweeping/wiping is clean. The dry cleaning module may also include an edge brush 152 having an axis of rotation that is angled relative to the floor for moving debris into the roller brush area of the cleaning module 150.

As an optional cleaning module, the automatic cleaning device may further include a wet cleaning module configured to clean at least a portion of the operation surface by wet cleaning; the wet type cleaning module comprises a water tank, a cleaning head, a driving unit and the like, wherein water in the water tank flows to the cleaning head along a water path, and the cleaning head cleans at least one part of an operation surface under the driving of the driving unit.

Therefore, the embodiment of the utility model provides an automatic cleaning device without a flip cover, which simplifies unnecessary elements of the automatic cleaning device and increases the design space of the dust box and the accommodating chamber thereof, and the same structure has the same technical effect, and some technical effects are not described herein again.
