DETAILED DESCRIPTION

[0051] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0053] A sweeping robot is a common smart home appliance that can automatically clean the floor in a room. In the related art, a sweeping robot includes a host and a cleaning mechanism, and the host is used to drive the cleaning mechanism to clean the floor. However, the current sweeping robot has a small cleaning range and is mainly used to clean the floor, but it is currently unable to effectively clean the skirting of the bottom wall of the wall.

[0054] In view of the above technical problems, the present disclosure provides a sweeping robot, such as Figure 1 As shown, the sweeping robot includes a main body 1, a first cleaning mechanism 2 and a second cleaning mechanism 3. The first cleaning mechanism 2 is connected to the main body 1 and is located below the main body 1. The first cleaning mechanism 2 is used to clean the floor. The second cleaning mechanism 3 is connected to the main body 1 and has a first state and a second state. Figure 1 and Fig.10 As shown in FIG. 1 , in the first state, the second cleaning mechanism 3 is retracted relative to the side of the main body. Figure 2 , Figure 3 and Fig.10 As shown, in the second state, the second cleaning mechanism 3 protrudes relative to the side of the main body 1, and the second cleaning mechanism 3 is used to clean the wall.

[0055] The host 1 has an edge sensor and a controller. The host 1 can determine the distance between the sweeping robot and the wall through the edge sensor, and control the second cleaning mechanism 3 to switch between the first state and the second state through the controller. When the edge sensor measures that the distance between the sweeping robot and the wall is far, the controller controls the second cleaning mechanism 3 to be in the first state, and the sweeping robot is only used to clean the floor. When the edge sensor measures that the distance between the sweeping robot and the wall is close, the controller sends a command to the second cleaning mechanism 3, so that the second cleaning mechanism 3 is in the second state, thereby completing the cleaning of the wall.

[0056] The technical solution provided by the embodiment of the present disclosure is that the sweeping robot is provided with a second cleaning mechanism 3. When the second cleaning mechanism 3 is in the first state, the second cleaning mechanism 3 is retracted relative to the side of the main body 1, so that the second cleaning mechanism 3 does not affect the first cleaning mechanism 2 cleaning the ground near the wall. When the second cleaning mechanism 3 is in the second state, the first cleaning mechanism 2 cleans the ground, and the second cleaning mechanism 3 protrudes relative to the side of the main body 1, so that it can clean the wall, thereby increasing the cleaning range of the sweeping robot.

[0057] Next, the implementation of the second cleaning mechanism 3 is exemplarily described.

[0058] In some examples, such as Figure 4 and Figure 5As shown, the second cleaning mechanism 3 includes a driving device 31, a connecting rod 32 and a cleaning component 33. One end of the connecting rod 32 is rotatably connected to the main machine 1, and the other end is connected to the cleaning component 33. The driving device 31 is used to drive the connecting rod 32 to rotate, so that the cleaning component 33 switches between a first state and a second state, wherein in the first state, the cleaning component 33 rotates to the bottom of the main machine 1, and in the second state, the cleaning component 33 rotates to protrude relative to the side of the main machine 1. The cleaning component 33 can also be called a rag.

[0059] like Figure 7 As shown, when the second cleaning mechanism 3 needs to clean the wall, the driving device 31 drives the connecting rod 32 to rotate, so that the connecting rod 32 drives the cleaning component 33 to rotate to the side of the main body 1. Figure 6 As shown, after the second cleaning mechanism 3 finishes cleaning the wall, the driving device 31 drives the connecting rod 32 to rotate, so that the connecting rod 32 drives the cleaning component 33 to rotate to the bottom of the main unit 1.

[0060] For example, Figure 6 and Figure 7 As shown, the cleaning member 33 may be circular, thereby facilitating cleaning the edge of a wall.

[0061] In some examples, such as Figure 6 and Figure 7 As shown, the driving device 31 includes a motor 311, a first push rod 312 and a second push rod 313. One end of the first push rod 312 is connected to the motor 311 in a transmission manner, and the other end is connected to the second push rod 313 in a rotational manner. One end of the second push rod 313 away from the first push rod 312 abuts against the connecting rod 32. The first push rod 312 and the second push rod 313 form a crank connecting rod mechanism. The motor 311 drives the connecting rod 32 to rotate through the first push rod 312 and the second push rod 313. When the first push rod 312 and the second push rod 313 are in a folded state, the second cleaning mechanism 3 is in a first state. When the first push rod 312 and the second push rod 313 are in an unfolded state, the second cleaning mechanism 3 is in a second state. Wherein, the motor 311 can be a stepping motor.

[0062] like Figure 6 As shown, when the first push rod 312 and the second push rod 313 are in the folded state, the axes of the first push rod 312 and the second push rod 313 form a certain angle. At this time, the distance between the motor 311 and the connecting rod 32 is short, so that the connecting rod 32 is stored inside the main unit 1, and the cleaning component 33 is located below the main unit 1.

[0063] like Figure 7As shown, when the first push rod 312 and the second push rod 313 are in the unfolded state, the angle between the first push rod 312 and the second push rod 313 is 180°. At this time, the distance between the motor 311 and the connecting rod 32 is long, and the first push rod 312 and the second push rod 313 push the connecting rod 32 to rotate to the outside of the main machine 1, so that the cleaning component 33 is located on the side of the main machine 1.

[0064] In some examples, such as Figure 6 As shown, the second push rod 313 includes a first rod body 3131 and a second rod body 3132. One end of the first rod body 3131 is rotatably connected to the first push rod 312, and the other end is connected to the second rod body 3132. The width D2 of the second rod body 3132 is greater than the width D1 of the first rod body 3131. The first rod body 3131 and the second rod body 3132 are an integrated structure.

[0065] When the driving device 31 drives the second cleaning mechanism 3 to switch between the first state and the second state, the second push rod 313 rotates, thereby causing the second rod body 3132 and the connecting rod 32 to slide relative to each other in the width direction of the second rod body 3132. Therefore, setting the width D2 of the second rod body 3132 larger can ensure that the second push rod 313 always abuts against the connecting rod 32.

[0066] The embodiment of the present disclosure does not specifically limit the implementation method of the driving device 31. In other examples, such as Figure 8 and Fig. 9 As shown, the driving device 31 includes a motor 311. One end of the connecting rod 32 is connected to the motor 311, and the other end is connected to the cleaning component 33. The motor 311 is used to drive the connecting rod 32 to rotate. In this way, the motor 311 can directly drive the connecting rod 32, thereby reducing the number of parts in the driving device 31 and simplifying the structure of the driving device 31.

[0067] In some examples, such as Figure 6 and Figure 7 As shown, the connecting rod 32 includes a rod body 321 and a sphere 322. One end of the rod body 321 is rotatably connected to the main unit 1, and the other end is connected to the sphere 322, and the sphere 322 is hinged to the cleaning member 33. In this way, the cleaning member 33 can be at any angle with the rod body 321, so that the angle of the cleaning member 33 can be changed with the change of the wall. For example, when the wall has an inclined surface, the cleaning member 33 can also be tilted accordingly, so that the cleaning member 33 can always fit the wall, thereby ensuring the cleaning effect of the cleaning member 33.

[0068] In some examples, such as Figure 2 As shown, the side wall of the main unit 1 has an opening 10. In the second state, the connecting rod 32 extends from the opening 10, thereby preventing the side wall of the main unit 1 from blocking the connecting rod 32.

[0069] In some examples, such as Figure 1 and Figure 2 As shown, the sweeping robot further includes a curtain 4, which is connected to the side wall of the main body 1. Figure 1 As shown, when the second cleaning mechanism 3 is in the first state, the curtain 4 is used to cover the opening 10 to prevent foreign matter from entering the interior of the main unit 1 through the opening 10, thereby damaging the main unit 1 and the driving device 31. Figure 2 As shown, when the second cleaning mechanism 3 is in the second state, the curtain 4 forms a certain angle with the side wall of the main body 1. When the connecting rod 32 rotates toward the outside of the main body 1, the curtain 4 will be lifted up under the push of the connecting rod 32, so that the connecting rod 32 extends out of the opening 10.

[0070] In some examples, the curtain 4 is a rubber sheet, so that the curtain 4 is soft and can be easily opened under the push of the connecting rod 32.

[0071] Of course, in other examples, the barrier curtain 4 may also be a rigid member, and the barrier curtain 4 is hinged to the side wall of the main unit 1 , so that the barrier curtain 4 can rotate with the rotation of the connecting rod 32 .

[0072] In some examples, when the second cleaning mechanism 3 is in the first state, the second cleaning mechanism 3 is used to clean the floor. In this way, the second cleaning mechanism 3 can clean both the wall and the floor, thereby enhancing the cleaning strength of the floor cleaning robot on the bottom surface.

[0073] In the above solution, the second cleaning mechanism 2 is connected to the main body 1 by rotation to switch between the first state and the second state. In other examples, the second cleaning mechanism 2 can also be connected to the main body 1 by sliding to switch between the first state and the second state.

[0074] like Fig.10 As shown, the second cleaning mechanism 3 includes a driving device 31 and a cleaning component 33. The driving device 31 is a push rod component, one end of the driving device 31 is connected to the main machine 1, and the other end is connected to the cleaning component 33. The driving device 31 is used to drive the cleaning component 33 to slide along the radial direction of the main machine 1.

[0075] In the first state, the driving device 31 drives the cleaning component 33 to slide in the direction close to the host 1. The cleaning component 33 can extend into the interior of the host 1 through the opening 10, or can be located outside the host 1 and fit against the outer wall of the host 1. In the second state, the driving device 31 drives the cleaning component 33 to slide in the direction away from the host 1.

[0076] In some examples, the driving device 31 may include a motor and a telescopic rod, and the motor drives the cleaning component 33 to switch between the first state and the second state by driving the telescopic rod to extend and retract.

[0077] In other examples, the driving device 31 may also include a motor, a gear and a push rod. The motor is connected to the gear, the push rod has a sawtooth structure, and the push rod is meshed with the gear. The motor drives the gear to rotate to make the push rod slide along the radial direction of the host 1, thereby driving the cleaning component 33 to switch between the first state and the second state.

[0078] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
