[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] The cleaning robot 100 according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 2 As shown, the cleaning robot 100 according to the embodiment of the present invention includes a machine body 10 , a cleaning component and a driving member 30 .

[0039] Specifically, the cleaning assembly is arranged at the bottom of the machine body 10, and the cleaning assembly is used to clean up garbage. The driving member 30 is arranged at the bottom of the machine body 10, and the driving member 30 is connected to the cleaning assembly. The driving member 30 drives the cleaning assembly to switch between a first state and a second state. When the driving member 30 drives the cleaning assembly to be in the first state, the cleaning assembly is stored at the bottom of the machine body 10, and the orthographic projection area of ​​the cleaning area of ​​the cleaning assembly relative to the bottom of the machine body 10 is smaller than the bottom cross-sectional area of ​​the machine body 10. When the driving member 30 drives the cleaning assembly to be in the second state, the cleaning assembly is unfolded relative to the bottom of the machine body 10, and the orthographic projection area of ​​the cleaning area of ​​the cleaning assembly relative to the bottom of the machine body 10 is larger than the bottom cross-sectional area of ​​the machine body 10.

[0040] In other words, see Figure 1 and Figure 2According to an embodiment of the present invention, the cleaning robot 100 is mainly composed of a machine body 10, a cleaning component and a driving member 30. The cleaning component is installed at the bottom of the machine body 10, and the cleaning component is mainly used to clean up garbage. The driving member 30 is installed at the bottom of the machine body 10, and the driving member 30 is connected to the cleaning component. The driving member 30 can drive the cleaning component to switch between the first state and the second state, so that the cleaning robot 100 can switch freely between the two modes. When the driving member 30 drives the cleaning component to be in the first state, see Figure 1 , the cleaning component can be stored at the bottom of the machine body 10. At this time, the cleaning area (cleaning area) of the cleaning component relative to the orthographic projection area on the bottom of the machine body 10 is smaller than the bottom cross-sectional area of ​​the machine body 10. The first state of the cleaning component can be understood as the normal cleaning mode of the cleaning robot 100. The cleaning area of ​​the cleaning component is relatively small, and can be used for cleaning in small scenes (areas with small environmental space).

[0041] When the driving member 30 drives the cleaning assembly to the second state, see Figure 2 , the cleaning component can be unfolded relative to the bottom of the machine body 10. At this time, after the cleaning component is unfolded, the cleaning area of ​​the cleaning component relative to the bottom of the machine body 10 is larger than the bottom cross-sectional area of ​​the machine body 10, which effectively increases the cleaning area of ​​the cleaning component. The second state of the cleaning component can be understood as the unfolded cleaning mode of the cleaning robot 100. The cleaning area of ​​the cleaning component is relatively large, and it can be used for cleaning in large scenes (areas with larger environmental spaces), effectively improving the cleaning efficiency.

[0042] It should be noted that the existing cleaning robot 100 has only one fixed cleaning mode (equivalent to the mode when the cleaning component of the present application is in the first state). The existing cleaning robot 100 has too low working efficiency in large scenes and cannot work flexibly in different scenes. It is easily affected by the site area and different models of robots need to be replaced, which is costly.

[0043] Therefore, according to the cleaning robot 100 of the embodiment of the present invention, the driving member 30 can drive the cleaning component to switch between the first state and the second state. When the cleaning component is in the first state, the cleaning component can be stored at the bottom of the machine body 10 to maintain a normal cleaning area. When the cleaning component is in the second state, the cleaning component can be unfolded relative to the bottom of the machine body 10 to increase the cleaning area and expand the cleaning range of the cleaning robot 100, so that the cleaning robot 100 can freely switch between the first state and the second state according to the size of the actual cleaning scene, meet the different cleaning needs of the cleaning staff, improve the cleaning efficiency of the cleaning robot 100, increase the versatility of the cleaning robot 100, and enhance the user experience.

[0044] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the cleaning assembly includes a plurality of cleaning discs 21 and a plurality of cleaning motors 22. Among them, the plurality of cleaning discs 21 can be movably mounted at the bottom of the machine body 10, and each cleaning disc 21 is mainly used to clean debris and other garbage on the ground. One of the cleaning discs 21 is connected to the driving member 30, and two adjacent cleaning discs 21 are rotatably connected to achieve garbage cleaning. Each cleaning motor 22 corresponds to a cleaning disc 21, and each cleaning motor 22 can drive the corresponding cleaning disc 21 to rotate, so as to achieve garbage cleaning of each cleaning disc 21.

[0045] When the driving member 30 drives the cleaning assembly to be in the first state, as shown in FIG. Figure 1 As shown, multiple cleaning discs 21 can be stored at the bottom of the machine body 10. At this time, the cleaning area enclosed by the multiple cleaning discs 21 is relatively small, and can be used for cleaning in small scenes (areas with small environmental space). Figure 2 As shown, multiple cleaning discs 21 are unfolded relative to the bottom of the machine body 10, and at least a portion of the cleaning discs 21 can extend out of the bottom of the machine body 10, thereby expanding the cleaning area and being applicable to cleaning in large scenes (areas with larger environmental spaces), thereby effectively improving cleaning efficiency. The cleaning robot 100 of the present invention can achieve efficient operation in both large and small scenes, is closer to the work needs of cleaning personnel, and improves cleaning efficiency.

[0046] In some specific embodiments of the present invention, there are three cleaning discs 21, each of which is provided with a cleaning motor 22, and one of the cleaning discs 21 is connected to the driving member 30. Two of the three cleaning discs 21 that are not connected to the driving member 30 are respectively provided with eccentric motors 23, and when the driving member 30 drives the cleaning assembly in a first state, the three cleaning discs 21 are arranged in a herringbone shape in the machine body 10; when the driving member 30 drives the cleaning assembly in a second state, the three cleaning discs 21 are arranged in a straight line.

[0047] That is to say, Figure 1 and Figure 2 As shown, the number of cleaning discs 21 can be set to three, and a cleaning motor 22 is respectively provided in each cleaning disc 21. One of the cleaning discs 21 is connected to the driving member 30, and the driving member 30 drives the cleaning disc 21 to move at the bottom of the machine body 10, thereby driving the other two cleaning discs 21 to be stored or unfolded at the bottom of the machine. Two cleaning discs 21 that are not connected to the driving member 30 among the three cleaning discs 21 are respectively provided with eccentric motors 23. By providing the eccentric motors 23, it is convenient to change the activity paths of the corresponding two cleaning discs 21, which is more conducive to the switching of the three cleaning discs 21 between the first state and the second state.

[0048] When the driving member 30 drives the cleaning assembly to be in the first state, see Figure 1 The three cleaning discs 21 can be arranged in a roughly herringbone shape in the machine body 10, and the centers of the three cleaning discs 21 can be connected to form a triangle. When the driving member 30 drives the cleaning assembly to the second state, see Figure 2 The three cleaning discs 21 are arranged in a straight line, which effectively increases the cleaning area of ​​the cleaning robot 100.

[0049] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the driving member 30 includes: a driving motor 31 and a push rod 32, the driving motor 31 is installed on the machine body 10, one end of the push rod 32 is connected to the driving motor 31, and the other end of the push rod 32 is connected to one of the cleaning discs 21. The driving motor 31 drives the push rod 32 to move, which can drive the cleaning disc 21 to switch between the first state and the second state. The cleaning robot 100 realizes the cleaning robot 100 in different modes (normal mode and expansion mode) through multi-motor cooperation (driving motor 31, cleaning motor 22, eccentric motor 23, etc.), and does not need to replace the cleaning robot 100 of different sizes to achieve the cleaning purpose. At the same time, it can also be directly and effectively copied to other cleaning robots 100, making the cleaning robot 100 more flexible, economical and efficient.

[0050] According to one embodiment of the present invention, the cleaning robot 100 further includes a detector and a controller.

[0051] Specifically, the detector is arranged in the machine body 10, and the detector is used to detect the surrounding environment and send out a corresponding detection signal. The controller is arranged in the machine body 10, and the controller is connected to the detector signal, and the controller is electrically connected to the driving member 30. The controller receives the detection signal and controls the driving member 30 to drive the cleaning component to switch between the first state and the second state according to the detection signal.

[0052] In other words, the cleaning robot 100 may also include a detector and a controller. Wherein, the detector is installed in the machine body 10, and the detector may be a laser, visual, ultrasonic or other sensor. The detector is used to detect the surrounding environment. The detector can determine whether the cleaning area is a large scene, and send a corresponding detection signal at the same time. The controller is installed in the machine body 10, and the controller is connected to the detector signal. The controller is electrically connected to the driver 30. The controller can receive the detection signal and control the driver 30 to drive the cleaning component to switch between the first state and the second state according to the detection signal. When the controller receives the detection signal of the large scene, the driver 30 is controlled to drive the cleaning component to unfold (stretch) to achieve large-area cleaning. When the controller receives the detection signal of the small scene, the driver 30 can be controlled to drive the cleaning component to be stored at the bottom of the machine body 10. At this time, the cleaning robot 100 is in normal cleaning mode, and the cleaning component does not need to be stretched. The cleaning robot 100 of the present invention can achieve efficient work in large and small scenes, is closer to the work needs of cleaning personnel, and improves cleaning efficiency.

[0053] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the cleaning robot 100 further includes two rear drive wheels 40 and a front steering wheel 50. The two rear drive wheels 40 are spaced apart and arranged relatively at the bottom of the machine body 10, and the front steering wheel 50 is arranged at the bottom of the machine body 10, and the front steering wheel 50 and the two rear drive wheels 40 are distributed in a triangular shape. The two rear drive wheels 40 and the front steering wheel 50 can realize the movement of the cleaning robot 100 on the ground.

[0054] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, a garbage chute is provided in the machine body 10, and a suction plate 60 is also provided at the bottom of the machine body 10. The suction plate 60 is roughly arc-shaped and is used to suck the garbage cleaned by the cleaning component into the garbage chute.

[0055] Of course, for those skilled in the art, other structures and working principles of the cleaning robot 100 are understandable and achievable, and will not be described in detail in the present invention.

[0056] In summary, according to the cleaning robot 100 of the embodiment of the present invention, the driving member 30 can drive the cleaning component to switch between the first state and the second state. When the cleaning component is in the first state, the cleaning component can be stored at the bottom of the machine body 10 to maintain a normal cleaning area. When the cleaning component is in the second state, the cleaning component can be unfolded relative to the bottom of the machine body 10 to increase the cleaning area and expand the cleaning range of the cleaning robot 100, so that the cleaning robot 100 can freely switch between the first state and the second state according to the size of the actual cleaning scene, meet the different cleaning needs of the cleaning staff, improve the cleaning efficiency of the cleaning robot 100, increase the versatility of the cleaning robot 100, and enhance the user experience.

[0057] According to a second aspect of the present invention, a cleaning method of a cleaning robot 100 is provided, which is applied to the cleaning robot 100 in the above embodiment. The cleaning method comprises:

[0058] S1, start the machine body 10;

[0059] S2. Control the driving member 30 to drive the cleaning component to switch between a first state and a second state, wherein when the driving member 30 drives the cleaning component to be in the first state, the cleaning component is stored at the bottom of the machine body 10, and the orthographic projection area of ​​the cleaning region of the cleaning component relative to the bottom of the machine body 10 is smaller than the bottom cross-sectional area of ​​the machine body 10; when the driving member 30 drives the cleaning component to be in the second state, the cleaning component is unfolded relative to the bottom of the machine body 10, and the orthographic projection area of ​​the cleaning region of the cleaning component relative to the bottom of the machine body 10 is larger than the bottom cross-sectional area of ​​the machine body 10.

[0060] That is to say, in the cleaning method of the cleaning robot 100 of the present invention, first, the machine body 10 can be started to put the cleaning robot 100 in a working state. Then, the driving member 30 can be controlled to drive the cleaning component to switch between the first state and the second state, so that the cleaning robot 100 can switch freely between the two modes. When the driving member 30 drives the cleaning component to be in the first state, the cleaning component can be stored at the bottom of the machine body 10. At this time, the cleaning area (cleaning area) of the cleaning component relative to the orthographic projection area on the bottom of the machine body 10 is smaller than the bottom cross-sectional area of ​​the machine body 10. The first state of the cleaning component can be understood as the normal cleaning mode of the cleaning robot 100. The cleaning area of ​​the cleaning component is relatively small, and can be used in small scenes (areas with smaller environmental space) for cleaning.

[0061] When the driving member 30 drives the cleaning component to be in the second state, the cleaning component can be unfolded relative to the bottom of the machine body 10. At this time, after the cleaning component is unfolded, the orthographic projection area of ​​the cleaning area of ​​the cleaning component relative to the bottom of the machine body 10 is larger than the bottom cross-sectional area of ​​the machine body 10, which effectively increases the cleaning area of ​​the cleaning component. The second state of the cleaning component can be understood as the unfolded cleaning mode of the cleaning robot 100. The cleaning area of ​​the cleaning component is relatively large, and can be used for cleaning in large scenes (areas with larger environmental spaces), effectively improving the cleaning efficiency.

[0062] In the process of controlling the driving member 30 to drive the cleaning component to switch between the first state and the second state, as shown in FIG. Figure 3 As shown, first, the surrounding environment can be detected and a corresponding detection signal can be sent out. Then, the driving member 30 can be controlled according to the detection signal to drive the cleaning assembly to switch between the first state and the second state.

[0063] The detector is installed in the machine body 10, and the detector can be a laser, visual, ultrasonic and other sensors. The detector is used to detect the surrounding environment. Through the detector, it can be determined whether the cleaning area is a large scene, and a corresponding detection signal is issued at the same time. The controller is installed in the machine body 10, and the controller is connected to the detector signal. The controller is electrically connected to the driver 30. The controller can receive the detection signal and control the driver 30 to drive the cleaning component to switch between the first state and the second state according to the detection signal. When the controller receives the detection signal of the large scene, it indicates that the current area can extend the cleaning component, and the driver 30 is controlled to drive the cleaning component to unfold (extend) to achieve large-area cleaning. When the controller receives the detection signal of the small scene, it indicates that the current area is in normal cleaning mode, and there is no need to extend the cleaning component. The driver 30 can be controlled to drive the cleaning component to be stored at the bottom of the machine body 10. At this time, the cleaning robot 100 is in normal cleaning mode, and the cleaning component does not need to be extended. The cleaning robot 100 of the present invention can achieve efficient work in large and small scenes, is closer to the work needs of cleaning personnel, and improves cleaning efficiency.

[0064] In summary, the cleaning method of the cleaning robot 100 according to the embodiment of the present invention can determine the scene size of the cleaning area, and enable the cleaning robot 100 to perform cleaning work in different modes (normal mode and expansion mode). There is no need to replace the cleaning robot 100 of different sizes to achieve the cleaning purpose. At the same time, it can also be directly and effectively copied to other cleaning robots 100, making the cleaning robot 100 more flexible, economical and efficient. In addition, the cleaning method of the cleaning robot 100 can meet the different cleaning needs of cleaning personnel, improve the cleaning efficiency of the cleaning robot 100, increase the versatility of the cleaning robot 100, and enhance the user experience.
