Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Fig. 1-4 is a schematic structural diagram of a robot according to an exemplary embodiment. As shown in Fig. 1-4, the robot 100 may be an automatic cleaning device such as a sweeping robot or a mopping robot, and the robot 100 may include a machine body 110 , a perception system 120 , a control system 130 , a driving system 140 , a cleaning system 150 , an energy system 160 and a human-computer interaction system 170 . in:

The main body 110 of the machine includes a forward portion 111 and a rearward portion 112, and has an approximately circular shape (both front and rear are circular), and may also have other shapes, including but not limited to an approximately D-shape with a front and rear circle.

The perception system 120 includes a position determination device 121 located above the machine body 110, a buffer 122 located at the forward portion 111 of the machine body 110, a cliff sensor 123, an ultrasonic sensor (not shown in the figure), an infrared sensor (not shown in the figure) output), 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 sensing devices, to the control system 130 provides various position information and motion status information of the machine. The position determining device 121 includes but not limited to a camera and a laser distance measuring device (LDS).

The forward part 111 of the machine body 110 can carry the buffer 122. When the driving wheel module 141 pushes the robot to walk on the ground during the cleaning process, the buffer 122 detects one or more of the driving paths of the robot 100 through a sensor system, such as an infrared sensor. Multiple events (or objects), the robot can pass through the events (or objects) detected by the buffer 122, such as obstacles, walls, and control the driving wheel module 141 to make the robot respond to the events (or objects) , such as moving away from obstacles.

The control system 130 is arranged on the circuit board in the main body 110 of the machine, and includes a computing processor, such as a central processing unit, an application processor, and a non-transitory memory, such as a hard disk, a flash memory, and a random access memory. Based on the obstacle information fed back by the laser ranging device, the robot uses positioning algorithms, such as SLAM, to draw an instant map of the environment in which the robot is located. And combined with the distance information and speed information fed back by the buffer 122, the cliff sensor 123 and the ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer and other sensing devices, it is comprehensively judged which working state the sweeper is currently in, such as Over the threshold, on the carpet, on the cliff, stuck above or below, the dust box is full, picked up, etc., will also give specific next-step action strategies for different situations, so that the robot's work is more in line with the owner's requirements , with a better user experience. Furthermore, the control system 130 can plan the most efficient and reasonable cleaning path and cleaning method based on the map information drawn by SLAM, greatly improving the cleaning efficiency of the robot.

Drive system 140 may steer robot 100 across the ground based on drive commands having distance and angular information, such as x, y, and theta components. The drive system 140 includes a drive wheel module 141,

The driving wheel module 141 can control the left wheel and the right wheel at the same time. In order to control the movement of the machine more precisely, preferably the driving wheel module 141 includes a left driving wheel module and a right driving wheel module respectively. The left and right drive wheel modules are opposed along a transverse axis defined by the main body 110 . In order for the robot to move more stably on the ground or to have a stronger movement capability, the robot may include one or more driven wheels 142, and the driven wheels include but not limited to universal wheels. The driving wheel module includes road wheels, a driving motor and a control circuit for controlling the driving motor. The driving wheel module can also be connected with a circuit for measuring driving current and an odometer. The driving wheel module 141 can be detachably connected to the main body 110, which is convenient for disassembly and maintenance. The drive wheels may have a biased drop suspension, movably secured, eg rotatably attached, to the robot body 110 and receive a spring bias biased downward and away from the robot body 110 . The spring bias allows the drive wheels to maintain contact and traction with the ground with a certain ground force, while the cleaning elements of the robot 100 also contact the ground 10 with a certain pressure.

The cleaning system 150 may be a dry cleaning system and/or a wet cleaning system. As a dry cleaning system, the main cleaning function comes from the cleaning system 151 composed of the roller brush structure, the dust box structure, the fan structure, the air outlet and the connecting parts between the four. The roller brush structure with 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 structure and the dust box structure, and then the suction gas is generated by the fan structure and passes through the dust box structure Suction dust box structure. The dust removal ability of the sweeper can be characterized by the cleaning efficiency DPU (Dust pick up efficiency) of the garbage. The cleaning efficiency DPU is affected by the structure and material of the roller brush, and is affected by the dust suction port, dust box structure, fan structure, air outlet and the four. The wind power utilization rate of the air duct formed by the connected components is affected by the type and power of the fan, which is a responsible system design issue. Compared with ordinary plug-in vacuum cleaners, the improvement of dust removal capacity is more meaningful for cleaning robots 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 100 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 increase. 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 system may also include a side brush 152 having an axis of rotation angled relative to the floor for moving debris into the area of the roller brush of the cleaning system 150 .

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.

In order to more clearly describe the behavior of the robot, the following orientation definitions are made: the robot 100 can travel on the ground through various combinations of movements relative to the following three mutually perpendicular axes defined by the main body 110: the lateral axis x, the front-back axis y and Center vertical axis z. The forward driving direction along the front-rear axis y is designated "forward" and the rearward driving direction along the front-rear axis y is designated "rearward". The transverse axis x extends substantially along the axis defined by the center point of the drive wheel module 141 between the right and left wheels of the robot. Wherein, the robot 100 can rotate around the x-axis. A "pitch" is when the forward part of the robot 100 is tilted up and the rearward part is tilted down, and "pitch" is when the forward part of the robot 100 is tilted down and the rearward part is tilted up. In addition, the robot 100 can rotate around the z-axis. In the forward direction of the robot, when the robot 100 is tilted to the right of the Y axis, it is "right turn", and when the robot 100 is tilted to the left of the y axis, it is "left turn".

In the above-mentioned robot 100, after the fan structure produces suction gas, cleaning objects such as dust swept up by the rolling brush structure can be sucked into the dust box structure; the cleaning objects are left in the dust box structure for collection and dumping, and The gas continues to enter the fan structure along the air duct, and is finally discharged through the air outlet. Therefore, the gas generated by the fan structure needs to pass through the following components in sequence: roller brush structure→dust box structure→fan structure→air outlet. Wherein, the dust box structure is usually set as a detachable structure, so that after the user disassembles the dust box structure from the robot 100 , dumps the collected dust and other cleaning objects, and then reinstalls it to the robot 100 for use.

However, the user may forget to install the dust box structure back to the robot 100 due to various reasons, so that when the robot 100 starts directly, dust, granular garbage, etc. may enter the fan structure under the suction force of the gas generated by the fan structure, resulting in motor failure. Intrusion by dust, damage of fan blades by granular garbage, etc. seriously affect the service life of the robot 100 .

In order to solve the above technical problems, an in-situ detection scheme for the dust box structure is proposed in the related art. In order to facilitate the understanding of the presence detection solution in the related art, the following description will be made in conjunction with the schematic diagram shown in FIG. 5 . Wherein, Fig. 5 is an exploded schematic view showing a structure of an automatic cleaning device according to an exemplary embodiment. As shown in Fig. 5 , the automatic cleaning device may include: a host 1 and a dust box structure 2; An accommodating cavity 11 , and the dust box structure 2 can be placed in the accommodating cavity 11 to be installed in the host 1 . Certainly, the accommodating cavity 11 may also be located at other positions of the host 1 , such as at the rear side of the host 1 (refer to the rearward direction of the y-axis shown in FIG. 4 ), and the present disclosure is not limited thereto.

Then, in the related art, by installing a micro switch on one side of the accommodating cavity 11, only when the dust box structure 2 is placed in the accommodating cavity 11, the micro switch can be touched, and the circuit of the automatic cleaning equipment enters the guide. Otherwise, the circuit of the automatic cleaning device will remain in the closed state, thereby realizing the presence detection of the dust box structure 2.

But, there is following problem in the above-mentioned scheme in the related art:

1. The shrapnel of the micro switch will be deformed after repeated use for a long time, so that it cannot accurately indicate whether the dust box structure 2 is in place. The service life of the micro switch is calculated by the number of presses, and there are large individual differences, and some micro switches will fail early.

2. There may be assembly differences in the assembly process of the micro switch, which may lead to poor consequences of the switch.

3. The micro switch of some structures adopts spring parts, and there are movable protrusions in the accommodation cavity 11 where the dust box structure 2 is placed, so the user may have a misoperation when loading and unloading the dust box structure 2 and touches the protrusions, thus As a result, the spring member is cut off and directly causes the micro switch to fail.

4. The dust in the dust box structure 2 may enter the circuit board of the micro switch, causing its circuit to fail.

In summary, due to serious defects in stability, reliability, and uniformity of mechanical parts such as micro switches, it is likely that the on-site detection of the dust box structure 2 cannot be accurately realized, and even the automatic cleaning equipment cannot work normally.

Therefore, by improving the structure of the automatic cleaning equipment such as the above-mentioned robot 100, the present disclosure can realize the in-position detection of the dust box structure 2, and help to improve its stability, reliability and uniformity.

As shown in Figure 5, in order to realize the in-position detection of the dust box structure 2, the dust box structure 2 may be provided with a non-contact induction element 31, and the host 1 may be provided with a non-contact induction matching element 32; The contact sensing element 31 and the non-contact sensing mating element 32 can realize non-contact mating sensing within a certain range, so there is no need for complicated mechanical structure and assembly relationship, as long as the non-contact sensing element 31 and the non-contact sensing mating are ensured When the element 32 is within a sensing distance range, the cooperative sensing between the two can be realized, thereby realizing the presence detection of the dust box structure 2 .

Therefore, by configuring the sensing distance range of the non-contact sensing element 31 and the non-contact sensing mating element 32 in advance, the non-contact sensing element 31 can be matched with the dust box structure 2 when the dust box structure 2 is installed on the host computer 1. The non-contact inductive matching element 32 enables the non-contact inductive matching element 32 to sense the non-contact inductive element 31 . Due to the non-contact induction scheme between the two, compared with the mechanical structure that needs to be assembled each time, it can avoid unexpected situations such as extrusion, breaking, and material aging that may be caused by the assembly process, thereby improving its application process. in the reliability.

1. Component type

All short-distance non-contact sensing elements can be applied to the technical solution of the present disclosure, and the present disclosure is not limited thereto. For ease of understanding, the non-contact sensing element 31 and the non-contact sensing matching element 32 that can be used are illustrated as follows:

1) Magnetic sheet and Hall sensor

In an exemplary embodiment, the non-contact sensing element 31 may be a magnetic sheet, and the non-contact sensing fitting element 32 may be a Hall sensor. By configuring the matching relationship between the magnetic field strength of the magnetic sheet and the inductive sensitivity of the Hall sensor, when the dust box structure 2 is installed on the host 1, the Hall sensor can just sense the magnetic sheet, thereby achieving magnetic alignment. Presence detection of the dust box structure 2 where the chip is located.

Of course, as mentioned above, the present disclosure does not limit the sensing direction between the non-contact sensing element 31 and the non-contact sensing mating element 32, so similar to the above-mentioned embodiment, the Hall sensor can be used as a non-contact sensing element. The component 31 is installed in the dust box structure 2, and the magnetic sheet is installed in the host 1 as the non-contact inductively matching component 32, which can also realize the above-mentioned in-position detection, which will not be repeated here.

2) Photocoupler

In another exemplary embodiment, the non-contact sensing element 31 may be the light emitting part of the optocoupler device, and the non-contact sensing matching element 32 may be the light receiving part of the optocoupler device. By considering the installation relationship between the dust box structure 2 and the host 1, the installation position and installation angle of the light-emitting part and the light-receiving part can be reasonably configured, so that the light-emitting part can be installed on the host 1 when the dust box structure 2 , to emit light that enables the light-receiving part to output a preset electrical signal, thereby realizing the presence detection of the dust box structure 2 where the light-emitting part is located.

Similarly, the light-receiving part of the optocoupler device can be installed in the dust box structure 2 as a non-contact inductive element 31, and the light-emitting part of the optocoupler device can be installed in the host 1 as a non-contact inductively matching element 32, The above-mentioned in-position detection can also be realized, which will not be repeated here.

2. Signal transmission

Control components are installed in the automatic cleaning equipment, such as the MCU in the control system 130 shown in FIG. Wherein, when the detection result is that the dust box structure 2 is in place, the automatic cleaning equipment can be allowed to start the cleaning operation; and when the detection result is that the dust box structure 2 is not in place, the automatic cleaning equipment is not allowed to start the cleaning operation, so as to avoid affecting the automatic cleaning. damage or adversely affect the internal structure of the device.

In order to make the control components in the automatic cleaning equipment know the detection result, at least one of the non-contact sensing element 31 and the non-contact sensing matching element 32 can be electrically connected to the automatic The control part in the cleaning device is used to inform the control part of its own sensing result; then, the control part can process and obtain the above detection result according to the obtained sensing result. For example, when the non-contact inductive element 31 is a magnetic sheet and the non-contact inductive matching element 32 is a Hall sensor, it is assumed that the Hall sensor is electrically connected to the MCU on the motherboard, then when the dust box structure 2 is not installed on the When the host is 1, the Hall sensor outputs a low level to the MCU, making the MCU determine that the dust box structure 2 is not in place; and when the dust box structure is installed on the host 1, the Hall sensor outputs a high level to the MCU, making it The MCU determines that dustbox structure 2 is present.

3. Installation location

In the technical solution of the present disclosure, the non-contact sensing element 31 can be installed in any position in the dust box structure 2, and the present disclosure is not limited to this; similarly, the non-contact sensing matching element 32 can be installed in the host 1 Any position of , and the present disclosure is not limited thereto. However, for the non-contact sensing element 31 , by changing its installation position on the dust box structure 2 , different presence detection effects can be achieved.

As shown in Figures 6-7, the dust box structure 2 may include: a dust box 21 and a filter screen 22, and the filter screen 22 is detachably installed on the dust box 21, so there are two installation positions for the non-contact sensing element 31 : installed in the dust box 21, or installed on the filter screen 22.

1) As shown in FIG. 6 , it is assumed that the non-contact sensing element 31 is installed in the dust box 21 . Then, when the detection result obtained by the automatic cleaning equipment is that the dust box structure 2 is in place, it can actually be determined that the dust box 21 containing the non-contact sensing element 31 has been installed in the accommodation chamber 11 of the host 1; The volume and shape between the net 22 and the dust box 21 are quite different, so that the filter net 22 is relatively inconspicuous to the user, so the user is likely to disassemble the filter net 22 without reinstalling it. , directly install the dust box 21 to the host 1 . Therefore, although the automatic cleaning device can obtain the detection result that the dust box structure 2 is in place, it cannot actually determine whether the "dust box structure 2" is complete, that is, whether it contains the filter screen 22, but the default is that the filter screen 22 has It is mounted on the dust box 21.

2) As shown in FIG. 7 , it is assumed that the non-contact sensing element 31 is installed on the filter screen 22 . Then, since the volume and shape between the filter screen 22 and the dust box 21 are quite different, it is impossible for the user to install the filter screen 22 to the main machine 1 alone, and the dust box 21 is omitted, so the following two situations will be caused: Two installation situations: (1) The user does not install the filter screen 22 to the dust box 21, but installs the dust box 21 to the host 1 alone. At this time, since the non-contact sensing element 31 is located on the filter screen 22, the automatic cleaning device cannot The dust box structure 2 is detected, so the detection result is that the dust box structure 2 is not in place; (2) the user installs the filter screen 22 to the dust box 21, then after the user installs the complete dust box structure 2 to the host 1, the device is automatically cleaned It can be determined that the dust box structure 2 is in place.

Therefore, by installing the non-contact sensing element 31 on the filter screen 22, not only can a complete on-site detection of the dust box structure 2 be performed, but also the filter screen 22 can be detected to ensure that the automatic cleaning equipment obtains the "dust box structure 2 When the detection result of "in position" is detected, the dust box structure 2 does contain the dust box 21 and the filter screen 22, thereby preventing the gas from being blown into the fan structure without being filtered by the filter screen 22, and preventing dust, granular garbage, etc. Then it blows into the fan structure and causes damage to the fan structure. Since the accumulated dust on the filter screen 22 will greatly reduce the air volume and affect the dust collection efficiency, the filter screen often needs to be cleaned by the user to keep the air passage unobstructed. After cleaning the filter screen 22, the user may forget to put it back and directly put the dust box 21 Put it into the host 1, once it is turned on and cleaned, it will directly cause dust and garbage to enter the fan structure and cause damage. In fact, it is not uncommon for automatic cleaning equipment such as sweeping robots to scrap the fan caused by forgetting to install the filter screen 22 . Due to the sheet structure of the filter screen 22, it is difficult to design mechanical parts on it for in-situ identification.

Optionally, the non-contact sensing element 31 is installed on any position of the frame of the filter screen 22 , for example, a magnetic piece is embedded on the plastic frame of the filter screen 22 .

4. Dust box structure 2

In the technical solution of the present disclosure, openings on at least two sides can be formed on the dust box 21: one side opening is the air inlet 211 on the dust box 21 shown in FIG. 8 , and the other side opening is the dust box 21 shown in FIG. 6 Wherein, as shown in Figure 6, the filter screen 22 can be installed at the air outlet 212, and by making the filter screen 22 cover the air outlet 212, it is ensured that cleaning objects such as dust stay in the dust box 21, avoiding It is blown into the subsequent fan structure through the air outlet 212.

In an exemplary embodiment, as shown in FIG. 8 , the dust box 21 can be further divided into: a dust box main body 21A and a side wall 21B provided with an air inlet 211 . Since the air inlet 211 is arranged on the side wall 21B, the specification of the side wall 21B must be larger than that of the air inlet 211. Therefore, after the side wall 21B is disassembled, a pouring port 213 with a size larger than the air inlet 211 can be formed, which is convenient for the user to clean the dust box 21. Dump the cleaning objects such as dust collected in the container.

Fig. 9 shows a sectional view of a cleaning system 150 (see Fig. 1 ) of an automatic cleaning device of an exemplary embodiment, the cleaning system 150 includes the above-mentioned dust box structure 2, a rolling brush structure 4 and a blower fan arranged in the host 1 Structure 5; when the fan structure 5 is in working condition, the gas in the external environment will enter the automatic cleaning equipment from the roller brush structure 4, and then pass through the left side of the dust box 21 in the dust box structure 2 (with the perspective shown in Figure 9 ) enters the dust box 21 through the air inlet 211, then enters the fan structure 5 through the air outlet 212 on the right side of the dust box 21 (with the perspective shown in Figure 9), and finally is discharged from the external environment by the fan structure 5. Then, through the flow of gas between the rolling brush structure 4, the dust box structure 2 and the fan structure 5, the cleaning objects such as dust swept up by the rolling brush structure 4 can be sent into the dust box 21 to realize the cleaning operation.

Wherein, the air inlet 211 on the left side of the dust box 21 faces toward the roller brush structure 4 obliquely below one side (that is, the left side shown in FIG. 9 ), and the plane where the air inlet 211 is located is perpendicular to The wind direction of the dust box 21, when the flowing gas enters the dust box 21 engulfing the cleaning object, it is first blown to the dust box top 214 at the obliquely upper side of the other side of the air inlet 211 (that is, the right side shown in FIG. 9 ), The wind speed of the flowing gas is reduced, so that the cleaning object directly falls from the top 214 of the dust box and remains in the dust box 21 . By configuring the angle of the air inlet 211, it is possible to prevent cleaning objects such as dust from falling onto the main brush of the rolling brush structure 4 when the automatic cleaning equipment stops cleaning. In addition, it can prevent the cleaning object from being directly blown to and adhered to the filter screen 22, preventing the filter screen 22 from being blocked.

Further, the air outlet 212 is also connected to the air inlet (not shown in FIG. 9 ) of the fan structure 5 in the host 1; wherein, the cross-sectional area of the filter screen 22 matches the cross-sectional area of the air inlet, so that the dust box 21 Gas can be smoothly guided between the fan structure 5: on the one hand, the cross-sectional area of the filter screen 22 should not be too large, so that there will be no sudden change between the dust box 21 and the fan structure 5, thereby ensuring that the wind in the dust box 21 can Leading into the air inlet of the fan structure 5 without eddy currents can improve the utilization rate of the air volume and reduce the noise; Too much reduction (for example, not less than the preset utilization rate) can prevent cleaning objects such as dust from blocking the filter screen 22, thereby ensuring the DPU of the automatic cleaning device.

In another embodiment of the automatic cleaning device, as shown in Figure 10, the fan structure 5 is located in the first space 21A among the dust box 21, and the filter screen 22 is located in the first space 21A where the fan structure 5 is located and the dust box 21 between the remaining spaces 21B. Then, the non-contact sensing element 31 can be installed on the frame of the dust box 21 or the filter screen 22 , and the non-contact sensing matching element 32 can be installed on the position of the host 1 as close as possible to the non-contact sensing element 31 .
