[0002] The roller brush is a commonly used component in cleaning robot equipment. It is usually installed at the bottom of the robot and cleans the ground by rotating at high speed. After long-term use, if the bristles of the roller brush are worn or there are debris attached to the bristles, the roller brush needs to be replaced or removed for cleaning. Because some robot equipment is large and heavy, it is inconvenient to flip the roller brush over and replace it during daily operation. In addition, the roller brush is at the bottom of the equipment and the condition of the bottom of the equipment cannot be seen. It is often not very convenient to operate, which causes certain difficulties when removing the roller brush. Summary of the invention

[0030] The conveniently replaceable cleaning brush mechanism and the cleaning robot of the present application will now be described in detail with reference to the accompanying drawings.

[0031] Please refer to Figure 1 The cleaning robot 300 provided in the embodiment of the present application includes a body 200 and a cleaning brush mechanism 100. The cleaning brush mechanism 100 is arranged at the bottom of the body 200 and is used to clean ground garbage.

[0032] Combined with reference Figures 1 to 4 The cleaning brush mechanism 100 includes a fixed cover plate 10, a positioning shaft 20, a brush group 30 and a connecting plate 40. A guide groove 11 is provided on the fixed cover plate 10. The cleaning brush mechanism 100 is arranged at the bottom of the machine body 200 through the fixed cover plate 10. The positioning shaft 20 is arranged on the fixed cover plate 10 and partially extends into the guide groove 11, and a plurality of bosses 21 are arranged on the end of the positioning shaft 20 extending into the guide groove 11. Bristles for cleaning garbage are arranged on the surface of the brush group 30, and the brush group 30 can slide in and out of the fixed cover plate 10 along the guide groove 11. The connecting plate 40 is detachably connected to one end of the brush group 30 and is movably snap-connected to the fixed cover plate 10, and a connecting hole 321 that can mesh with the plurality of bosses 21 is provided on the other end of the brush group 30. The bayonet connection method of the fixed cover plate 10 and the connecting plate 40 is a detachable snap-connection.

[0033] In the cleaning brush mechanism 100, when installing the brush set 30, the brush set 30 is slid into the fixed cover plate 10 along the guide groove 11 until the connection hole 321 at one end of the brush set 30 is meshed with the multiple bosses 21 on the end of the positioning shaft 20 located in the guide groove 11, and then the connecting plate 40 is connected to the other end of the brush set 30 and snap-fastened on the fixed cover plate 10. When replacing the brush set 30, the fixed cover plate 10 and the connecting plate 40 are snap-fastened and separated, and the connecting plate 40 connected to the brush set 30 is disassembled, and the connecting hole 321 is separated from the multiple bosses 21 by pulling the brush set 30 until the brush set 30 slides out of the fixed cover plate 10 along the guide groove 11. The cleaning brush mechanism 100 realizes the installation of the brush set 30 on the bottom of the robot and the removal of the brush set 30 from the bottom of the robot through the detachable connection between multiple components and the brush set 30 being able to slide in and out of the guide groove 11, so that the brush set 30 can be easily replaced without flipping the robot device and when the bottom of the robot cannot be seen.

[0034] In one embodiment of the application, the connection hole 321 is a spline-shaped hole, and a plurality of bosses 21 are spaced apart to form a circle, and a circle of bosses 21 can be spline-connected to the spline-shaped hole; wherein the brush set 30 can be a roller brush.

[0035] like Figure 4 As shown, the fixed cover plate 10 is provided with a plurality of springs 12 located in the guide groove 11 , and the plurality of springs 12 are arranged around the end portion of the positioning shaft 20 extending into the guide groove 11 .

[0036] Combined with reference Figure 3 and Figure 5The brush set 30 includes a brush barrel 31 with bristles on the surface, a connecting rod 34, and a first end cover 32 and a second end cover 33 arranged at two opposite ends of the brush set 30. The two ends of the connecting rod 34 are respectively connected to the first end cover 32 and the second end cover 33, and the connecting hole 321 is arranged on the first end cover 32 and is detachably connected to the connecting plate 40.

[0037] Furthermore, a receiving groove matching the second end cover 33 is provided on the connecting plate 40, and a buckle plate rotatably provided on the fixed cover plate 10 is provided on one end of the fixed cover plate 10 through which the brush set 30 enters and exits. When the brush set 30 needs to be installed on the fixed cover plate 10, the second end cover 33 is buckled in the receiving groove, and the buckle plate is rotated so that the buckle plate buckles and presses the connecting plate 40.

[0038] like Figure 3 and Figure 4 As shown, the connection between the first end cover 32 and the connecting rod 34 forms a T-shaped structure 35, and similarly, the connection between the second end cover 33 and the connecting rod 34 forms a T-shaped structure 35. The guide groove 11 has a positioning groove 111 extending from the side of the brush group 30 along the sliding path of the brush group 30, and the cross section of the positioning groove 111 matches the aforementioned T-shaped structure 35, that is, the cross section of the positioning groove 111 is also T-shaped, and the cross section of the positioning groove 111 is perpendicular to the aforementioned extension direction of the positioning groove 111. Among them, it can be designed in advance during the design, when the T-shaped structure 35 is positioned in the positioning groove 111, as the brush group 30 is pushed to slide into the fixed cover plate 10, it can be convenient for the connecting hole 321 and the multiple bosses 21 to mesh; in this way, when the brush group 30 is subsequently installed, the T-shaped structure 35 is placed in the positioning groove 111 to complete the subsequent installation, that is, the T-shaped structure 35 and the positioning groove 111 play a marking and positioning role.

[0039] like Figure 2 and Figure 4 As shown, the cleaning brush mechanism 100 further includes a T-shaped structure 50 disposed on the fixed cover plate 10, the T-shaped structure 50 is connected to the positioning shaft 20 and is used to drive the positioning shaft 20 to rotate. Specifically, the T-shaped structure 50 further includes a motor 51, a driving wheel 52 connected to the motor 51 and driven to rotate by the motor 51, a driven wheel on which the positioning shaft 20 is disposed, and a synchronous belt 54 that drives and connects the driving wheel 52 and the driven wheel 53. When the motor 51 drives the driving wheel 52 to rotate, the synchronous belt 54 drives the driven wheel 53 to rotate, thereby driving the positioning shaft 20 on the driven wheel 53 to rotate, and finally the brush group 30 rotates following the positioning shaft 20 to clean the garbage on the ground.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
