Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Numerous specific details are set forth in the description below in order to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention, and thus the invention is not limited by the specific embodiments disclosed below.

All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention.

The present invention provides a sweeping robot comprising: a lower body 100 and a movable body 200, and the movable body 200 includes a dust collecting box. The movable body 200 is movably connected to the lower body 100 such that the sweeping robot has a folded position (FIG. 1) and a deployed position (FIG. 2); the sweeping robot can execute when the movable body moves relative to the lower body in the folded position and the deployed position. The cleaning operation; and, as the movable body moves relative to the lower body, the size of the cleaning robot in the vertical direction also changes.

In the present embodiment, the movable body 200 and the lower body 100 are rotatably connected. At the folded position, at least a portion of the movable body 200 is positioned above the lower body 100 to reduce the lateral dimension of the sweeping robot; when the position is deployed, the movable body 200 may be no higher than the upper surface of the lower body 100.

Of course, the movable body and the lower body can also be connected by slipping or the like, as long as the connection form of the two can bring about the dimensional change of the cleaning robot in the lateral direction and the vertical direction (height).

As described above, in the cleaning robot, at least in the folded position, at least a portion of the movable body 200 is positioned above the lower body 100 to reduce the lateral dimension of the cleaning robot. In the deployed position, the movable body 200 is not higher than the upper surface of the lower body 100. Therefore, the sweeping robot can be adjusted to the folded position to clean the area with a small lateral space, and the sweeping robot can be adjusted to the unfolded position to clean the low-lying area with a small vertical space, so the sweeping robot can adapt to a small space in the vertical direction. (low space), which can adapt to a small horizontal space, and the height of the height of the folding robot is increased in the folding position, but it is not necessary to maintain the height at all. Dimensions (can be adjusted to the unfolded position as needed to reduce the height of the whole machine), the sweeping robot increases the lateral dimension in the unfolded position but does not have to maintain this lateral dimension at all times (can be adjusted to the folded position as needed to reduce the horizontal dimension of the whole machine) So the sweeping robot is well converted through different positions. Both large volume and strong space adaptability are taken into consideration.

The sweeping robot is also equipped with a detector, a controller and a rotary drive. The controller is electrically connected to the detector and the rotation driving device respectively, and is configured to control the rotation of the movable body to drive the rotating body according to the detection information of the detector. According to a preferred embodiment of the invention, the detector is a distance sensor 3. The distance sensor 3 is disposed on the movable body 200.

The spatial information of the cleaning robot can be detected in real time, and the spatial information can be transmitted to the controller; then the controller can control the rotation driving device to drive the movable body 200 to rotate according to the spatial information in real time. In the specific work, the distance sensor 3 can detect the environment size faced by the cleaning robot in real time. For example, when the distance sensor 3 detects a low space, the detection signal can be transmitted to the controller, and the controller controls the rotary driving device to drive the movable body 200 to expand. The position is rotated, and when the movable body 200 is brought into a position capable of entering a low space, the rotation driving device is stopped to keep the movable body 200 at this position, so as to lower the overall height of the cleaning robot, so that the cleaning robot can be about to Work in the low space that enters. Similarly, when leaving the low space, the distance sensor 3 causes the controller to control the rotary driving device to drive the movable body 200 to rotate to the folded position by transmitting a corresponding signal, thereby causing the cleaning robot to gradually become higher. In summary, the distance sensor 3 can transmit signals to the controller by transmitting different environmental signals to cause the controller to control the rotary drive to rotate and hold the movable body 200 at any position between the folded position and the deployed position (including the folded position and Expand position). It can be seen that the sweeping robot can automatically and intelligently adapt to complex environmental requirements.

According to a preferred embodiment of the present invention, when the position is folded, the size of the cleaning robot in the vertical direction is between 170 and 200 mm; and in the unfolded position, the size of the cleaning robot in the vertical direction is between 70 and 100 mm.

According to a preferred embodiment of the present invention, in the deployed position, the whole body composed of the lower body 100 and the movable body 200 is circular or circular in cross section perpendicular to the vertical direction, and this design makes the sweeping robot encounter obstacles.

The rotation of the motor 1 can control the rotation of the rotating body 201, thereby driving the dust box to rotate. In addition, a side of the second side wall 102 facing the first side wall 101 may be provided with a circular groove 104, and the rotating body 201 is provided with an annular boss portion 202 rotatably engaged in the circular groove 104, the axis of the circular groove 104 It is disposed coaxially with the hinge shaft 103.

The bottom of the lower body 100 may be provided with a structure such as a traveling wheel, a cleaning member, or the like for cleaning the ground or the like. In order to realize the automatic cleaning of the cleaning components of the cleaning robot, a cleaning base station of the cleaning robot is also provided. The following description will be made by the following drawings and embodiments. For the sake of simplicity, the following drawings are schematic diagrams of the structure of the cleaning robot, although The sweeping robot of the drawing is not identical in structure, but is essentially the same and does not affect the implementation of the following technical solutions.

8 is a schematic diagram of an exemplary application environment of a cleaning robot. As shown in FIG. 8, in an exemplary application environment, the cleaning robot 10 can be, for example, an automatic mopping machine, and the cleaning robot 10 can automatically walk in a working area 30 (eg, an indoor area) within the boundary 50, The floor (such as the floor) in the work area 30 is cleaned.

9 is a block diagram of a cleaning robot according to an embodiment. The sweeping robot can be used to clean the ground. As shown in FIG. 9, the cleaning robot further includes a cleaning component 12 disposed at the bottom of the lower body 100 to clean the ground; the controller further includes a first control module 13.

FIG. 10 is a flow chart showing the configuration of a first control module 13 of a cleaning robot according to an embodiment. As shown in FIG. 10, the first control module 13 is configured to:

Step S101, determining whether the cleaning component meets a cleaning condition;

Step S102, in a case where the cleaning component satisfies the cleaning condition, the cleaning robot is controlled to go to the cleaning position of the cleaning base station.

The cleaning robot can go to the cleaning position of the cleaning base station when the cleaning component satisfies the cleaning condition, so as to wet and clean the cleaning component, so that the cleaning robot can realize a fully automatic ground cleaning process.

Figure 11 is a schematic view of a sweeping robot. As shown in FIG. 11, in one possible implementation, the cleaning robot may include a cleaning component 12. The cleaning member 12 can be, for example, a fleece roller brush or roller disposed at the bottom of the lower body 100, and can be rotated by a driving member 14 (for example, a motor) to clean the floor.

In a possible implementation manner, the first control module 13 may be any processing component capable of performing data processing, such as a single chip microcomputer, a CPU, an MPU, an FPGA, and the like disposed in the device body, and the first control module 13 may be implemented by a dedicated hardware circuit. It can also be implemented by a general processing component in combination with executable logic instructions to perform the processing of the first control module 13.

In a possible implementation manner, the cleaning robot may further include a storage module (not shown) to store data generated by the first control module 13.

In a possible implementation manner, the first control module 13 can determine whether the cleaning component 12 meets the cleaning conditions. For example, determining whether the cleaning member 12 satisfies the cleaning condition may include determining that the cleaning member 12 satisfies the cleaning condition in a case where the walking time of the cleaning robot reaches the second time threshold. When the mopping time of the cleaning robot (automatic mopping robot) reaches a certain time threshold (second time threshold), it can be considered that the cleaning member 12 (flannel roller brush) needs to be cleaned to meet the cleaning conditions. The second time threshold may be a preset time threshold of the system, or may be set by the user or set according to environmental conditions. For example, the second time threshold may be set to be longer when the environment in which the cleaning robot is located is relatively wet; when the environment is drier, the second time threshold is set to be shorter. The disclosure does not limit the specific value of the second time threshold.

In a possible implementation manner, determining whether the cleaning component 12 meets the cleaning condition may further include: determining that the cleaning component meets the cleaning condition when the walking region of the cleaning robot reaches the region threshold. When the mopping area of the cleaning robot (automatic mopping robot) reaches a certain area (area threshold), it can be considered that the cleaning member 12 (flannel roller brush) needs to be cleaned to meet the cleaning conditions. The threshold of the area may be an area threshold preset by the system, or may be set by the user or set according to the environment. For example, different zone thresholds may be set depending on the type of ground (eg, floor, floor tiles) that the cleaning robot cleans. The disclosure does not limit the specific value of the area threshold.

In a possible implementation manner, when the first control module 13 determines that the cleaning component 12 meets the cleaning condition, the cleaning robot can be controlled to go to the cleaning position of the cleaning base station. For example, the first control module 13 may plan a walking path of the cleaning robot according to the current position of the cleaning robot and the position of the cleaning base station, and control the cleaning robot to go to the cleaning position of the cleaning base station according to the walking path.

Figure 12 is a schematic diagram of a cleaning robot and a cleaning base station. In a possible implementation manner, as shown in FIG. 12, the cleaning base station 80 may have a cleaning tank 82 at the cleaning position, and the cleaning tank 82 may contain a cleaning liquid (for example, clean water). When the cleaning robot 10 reaches the cleaning position, the cleaning member 12 (flannel roller brush) may all enter or partially enter the cleaning tank 82 of the cleaning base station 80, so that the cleaning member 12 contacts the cleaning liquid in the cleaning tank 82, thereby cleaning the cleaning member. 12 for cleaning.

FIG. 13 is a flow chart showing the configuration of the first control module 13 of the cleaning robot. In a possible implementation manner, as shown in FIG. 13, the first control module 13 is further configured to:

Step S103, in a case where the cleaning robot is in the cleaning position, the cleaning component is controlled to rotate at a first speed, wherein the cleaning components all enter or partially enter the cleaning tank of the cleaning base station.

For example, as shown in FIG. 12, when the cleaning robot 10 reaches the cleaning position, the cleaning member 12 may all enter or partially enter the cleaning tank 82 of the cleaning base station 80 to cause the cleaning member 12 to contact the cleaning liquid in the cleaning tank 82. When the cleaning robot 10 is in the cleaning position, the first control module 13 can control the rotation of the cleaning member 12 so that the cleaning liquid can be washed to the entire roller of the cleaning member 12, thereby improving the cleaning effect of the cleaning member 12. Also, by controlling the cleaning member 12 to rotate at an appropriate speed (first speed), it is possible to prevent the water (washing liquid) from splashing outside the washing tank 82 while ensuring the cleaning effect, and to cause the cleaning robot 10 to clean when leaving the washing base station 80. Component 12 has a suitable humidity. The first speed may be a preset cleaning rotation speed of the cleaning member 12, which is not limited in the present disclosure.

Figure 14 is a flow chart showing the configuration of the first control module 13 of the cleaning robot. In a possible implementation manner, as shown in FIG. 14, the first control module 13 is further configured to:

Step S104: If the time when the cleaning robot is in the cleaning position reaches a first time threshold, the cleaning robot is controlled to leave the cleaning base station.

For example, after the cleaning robot is in the cleaning position for a certain time (first time threshold), it can be considered that the cleaning of the cleaning member 12 has achieved the cleaning effect, and the cleaning can be stopped. At this time, the first control module 13 can control the cleaning robot to leave the cleaning base station and return to the working area to continue the cleaning operation of the ground. The first time threshold may be a preset time threshold of the system, which is not limited in this disclosure.

In a possible implementation manner, the first control module 13 can also control the cleaning robot to clean a certain number of times. For example, when the floor cleaned by the cleaning robot is dirty, the cleaning part 12 to be cleaned may also be dirty, and may require multiple cleanings. In this case, the user can set the number of times the cleaning robot is cleaned, for example, three times. When the cleaning robot is in the cleaning position, the first control module 13 can control the cleaning component to stop for a certain period of time after rotating for a certain period of time (for example, the first time threshold) (waiting to clean the cleaning tank of the cleaning base to replace the cleaning liquid), and then continue to rotate. The time until the specified number of cleanings is completed. The specific setting manner of the cleaning times of the cleaning robot is not limited in the present disclosure.

In a possible implementation manner, as shown in FIG. 11 and FIG. 12, the cleaning robot 10 may further include:

The charging member 15 and the charging member 15 can contact the charging stand 88 of the cleaning base station 80 to charge the cleaning robot.

For example, the charging component 15 can include a charging electrode located in front of the cleaning robot 10. A charging stand 88 provided in the cleaning base station 80 can be used to charge the cleaning robot when the cleaning robot is in the cleaning position.

In a possible implementation manner, the first control module 13 may determine whether the cleaning robot needs to be charged, for example, whether the battery power of the cleaning robot is lower than a certain threshold, or whether the cleaning robot completes the cleaning area under the path planning. If the first control module 13 determines that the cleaning robot needs to be charged (for example, the battery power is lower than a certain threshold), then the cleaning robot is controlled to go to the cleaning position of the cleaning station. When the cleaning robot is in the cleaning position, the charging electrode of the charging member 15 can contact the charging stand 88 to charge the cleaning robot. On the other hand, if the first control module 13 determines that the cleaning robot does not need to be charged, when the cleaning robot is in the cleaning position, the charging electrode of the charging member 15 may not contact the charging stand 88, and only the cleaning member 12 of the cleaning robot is cleaned.

In a possible implementation, when the cleaning robot is in the cleaning position and needs to be charged, the cleaning operation and the charging operation can be performed simultaneously. In this case, the first time threshold of the cleaning robot in the cleaning position may be a time that both the cleaning operation and the charging operation can be completed (for example, the time required for charging > the time required for cleaning, the first time threshold may be charging) Time required). When the first time threshold is reached, the cleaning robot can be controlled to leave the cleaning base station. In this way, cleaning and charging can be performed simultaneously when charging is required, which improves the efficiency of use of the device.

In a possible implementation manner, when the cleaning robot performs the cleaning operation and the charging operation at the same time, after the cleaning operation, the cleaning tank 82 of the cleaning base station 80 can discharge the sewage; before the charging operation is completed, and the cleaning robot starts again, the cleaning is performed. The cleaning tank 82 of the base station 80 can be filled with clean water to wet the cleaning member.

Figure 15 is a block diagram of a cleaning base station for a cleaning robot in accordance with an embodiment. As shown in FIG. 15, the cleaning base station 80 includes: a base station body 81; a cleaning tank 82 located on the base station body, having a water inlet 821 and a water outlet 822, wherein the water inlet 821 allows the cleaning liquid to be injected into the cleaning tank. The water outlet 822 allows the cleaning liquid to drain out of the cleaning tank; the second control module 83 is configured to: control the water inlet and the water outlet to operate separately, inject cleaning liquid into the cleaning tank or from the cleaning The tank drains the cleaning solution.
