As shown in Figures 1-2, the automatic cleaning equipment can be a vacuum robot, a mopping/scrubbing robot, or a window climbing robot, etc. The automatic cleaning equipment can include a mobile platform 100, a perception 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 .

The mobile platform 100 may be configured to automatically move in a target direction on the operating surface. The operation surface may be the surface to be cleaned by the automatic cleaning equipment. In some embodiments, the automatic cleaning equipment can be a mopping robot, and the automatic cleaning equipment works on the ground, and the ground is the operating surface; the automatic cleaning equipment can also be a window cleaning robot, and the automatic cleaning equipment works on the ground The outer surface of the glass works, and the outer surface of the glass is the operation surface; the automatic cleaning equipment can also be a pipeline cleaning robot, and the automatic cleaning equipment works on the inner surface of the pipeline, and the inner surface of the pipeline is the operation surface. Purely for the purpose of illustration, the following description in this application takes the automatic cleaning device as an example of a floor mopping robot for illustration.

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 based on unexpected environmental inputs; the non-autonomous mobile platform itself cannot make adaptive decisions based on unexpected environmental inputs. Operational decision-making, but it can execute established procedures or operate according to certain logic. Correspondingly, when the mobile platform 100 is an autonomous mobile platform, the target direction can be determined by the automatic cleaning device; when the mobile platform 100 is a non-autonomous mobile platform, the target direction can be set by the 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 determination 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 located at the bottom of the mobile platform, an ultrasonic sensor (not shown), an infrared sensor (not shown in the figure), magnetometer (not shown in the figure), accelerometer (not shown in the figure), gyroscope (not shown in the figure), odometer (not shown in the figure) and other sensors The device provides various position information and motion state information of the machine to the control system 130.

In order to more clearly describe the behavior of the autonomous cleaning device, the following orientation definitions are made: The autonomous cleaning device can travel on the ground through various combinations of movements relative to the following three mutually perpendicular axes defined by the mobile platform 100: the lateral axis Y, the front-to-back Axis X and central vertical axis Z. The forward driving direction along the front-rear axis X is designated "forward" and the rearward driving direction along the front-rear axis X is designated "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 automatic cleaning device. Wherein, the automatic cleaning device can rotate around the Y axis. A self-cleaning device is "pitched" when the forward part is sloped upwards and the rearward part is sloped downwards, and "pitched" is when the forward part of the automatic cleaning device is sloped downwards and the rearward part is sloped upwards. In addition, the automatic cleaning device can rotate around the Z axis. In the forward direction of the automatic cleaning device, when the automatic cleaning device tilts to the right of the X-axis, it is a "right turn", and when the automatic cleaning device tilts to the left of the X-axis, it is a "left turn".

Specific types of the location determination device 121 include but are not limited to cameras and laser distance measuring devices (LDS).

Each component in the perception system 120 can operate independently or jointly to achieve the purpose function more accurately. The surface to be cleaned is identified by the cliff sensor 123 and the ultrasonic sensor to determine the physical characteristics of the surface to be cleaned, including surface material, cleanliness, etc., and can be combined with cameras, laser distance measuring devices, etc. to make more accurate judgments.

For example, the ultrasonic sensor can be used to determine whether the surface to be cleaned is a carpet. If the ultrasonic sensor determines that the surface to be cleaned is made of carpet, the control system 130 controls the automatic cleaning device to perform carpet mode cleaning.

The forward part 111 of the mobile platform 100 is provided with a buffer 122. During the cleaning process, when the driving wheel assembly 141 pushes the automatic cleaning device to walk on the ground, the buffer 122 detects that the automatic cleaning device is in the driving path through a sensor system, such as an infrared sensor. One or more events (or objects), the automatic cleaning device can pass through the events (or objects) detected by the buffer 122, such as obstacles, walls, and control the driving wheel assembly 141 so that the automatic cleaning device can respond to the event (or an object) to respond, such as moving away from an obstacle.

The control system 130 is arranged on the main board of the mobile platform 100, and includes a computing processor, such as a central processing unit, and an application processor, communicating with a non-transitory memory, such as a hard disk, flash memory, and random access memory. The application processor is configured to receive the environmental information sensed by multiple sensors from the perception system 120, and use a positioning algorithm, such as SLAM, to draw real-time information in the environment where the automatic cleaning device is located according to the obstacle information fed back by the laser ranging device. map, and autonomously determine a driving route according to the environmental information and the environmental map, and then control the drive system 140 to perform forward, backward, and/or steering operations according to the autonomously determined driving route. Further, the control system 130 may also decide whether to activate the cleaning module 150 to perform cleaning operations according to the environmental information and the environmental map.

In some embodiments, the control system 130 can comprehensively determine the distance information and speed information fed back by the buffer 122, the cliff sensor 123, and ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, odometers and other sensing devices. What is the current working state of the machine, such as crossing the threshold, on the carpet, on the cliff, stuck above or below, full of dust boxes, picked up, etc., and will give specific next-step action strategies for different situations. It makes the work of the automatic cleaning equipment more in line with the owner's requirements and has a better user experience. Furthermore, the control system can plan the most efficient and reasonable cleaning path and cleaning method based on the real-time map information drawn by SLAM, greatly improving the cleaning efficiency of automatic cleaning equipment.

Drive system 140 may execute drive commands to steer the autonomous cleaning device across the ground based on specific distance and angular information, such as x, y, and theta components. As shown in FIG. 2, the driving system 140 includes a driving wheel assembly 141, and the driving system 140 can simultaneously control the left wheel and the right wheel. For more precise control of machine motion, drive system 140 includes left and right drive wheel assemblies, respectively.

In order for the automatic cleaning equipment to move more stably on the ground or have a stronger movement ability, the automatic cleaning equipment can include one or more steering assemblies 142, and the steering assembly 142 can be a driven wheel or a driving wheel, and its structural form Including but not limited to universal wheels, the steering assembly 142 may be located in front of the driving wheel assembly 141 .

Energy system 160 includes rechargeable batteries, such as NiMH and Lithium batteries. The rechargeable battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit and a battery undervoltage monitoring circuit, and the charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit are connected with the single-chip microcomputer control circuit. The main unit is charged by being connected to the charging pile through the charging electrodes arranged on the side or the bottom of the fuselage. If there is dust on the exposed charging electrodes, due to the cumulative effect of charges during the charging process, the plastic body around the electrodes will be melted and deformed, and even the electrodes themselves will be deformed, making it impossible to continue charging normally.

The human-computer interaction system 170 includes buttons on the panel of the host computer, which are used for the user to select functions; and may also include a display screen and/or an indicator light and/or a horn, and the display screen, the indicator light and the horn show the user the current state of the machine or Functional options; may also include mobile phone client programs. For path-guided cleaning equipment, the mobile phone client can show the user a map of the environment where the equipment is located, as well as the location of the machine, and can provide users with more abundant and humanized functional items.

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 fan, and an air outlet. The roller brush that has a certain interference with the ground sweeps up the garbage on the ground and rolls it to the front of the dust suction port between the roller brush and the dust box, and then is sucked into the dust box by the suction gas generated by the fan and passed through the dust box. The dust removal ability of the sweeper can be characterized by the cleaning efficiency DPU (Dust pickup efficiency) of the garbage. The cleaning efficiency DPU is affected by the structure and material of the roller brush, and is affected by the suction port, dust box, fan, air outlet and the connecting parts between the four. The wind power utilization rate of the formed air duct is affected by the type and power of the fan, which is a complex system design issue. Compared with ordinary plug-in vacuum cleaners, the improvement of dust removal capacity is more meaningful for cleaning automatic cleaning equipment with limited energy. Because the improvement of dust removal ability directly and effectively reduces the energy requirements, that is to say, the original machine that can clean 80 square meters of ground with one charge can evolve to clean 180 square meters or more with one charge. And the service life of the battery with reduced charging times will also be greatly increased, so that the frequency of user replacement of the battery will also be reduced. More intuitively and importantly, the improvement of the dust removal ability is the most obvious and important user experience, and the user will directly draw the conclusion of whether the sweeping/wiping is clean. The dry cleaning module may also include a side brush 152 having an axis of rotation that is angled relative to the ground for moving debris into the area of the roller brush of the cleaning module 150 .

In some embodiments, the automatic cleaning device may further include a wet cleaning module configured to clean at least a part of the operation surface in a wet cleaning manner; wherein the wet cleaning module includes a water tank, a cleaning head, a drive unit, etc. , wherein the water in the water tank flows along the waterway to the cleaning head, and the cleaning head cleans at least a part of the operation surface driven by the driving unit.
