As shown in Figures 2 to 6, the roller brush device provided by the embodiment of the present application includes a driving mechanism 10 and a roller brush structure 20. The driving mechanism 10 includes a housing 11 and an output shaft 12, the housing 11 has a first end and a second end opposite to each other, the first end is rotatably mounted to the body 30 of the cleaning robot, and the output shaft 12 protrudes from the second end and serves as a free end. The roller brush structure 20 includes a roller 21, an end assembly component 22 and a brush cover 23, the first end of the roller 21 has an insertion port 211, a connecting portion 212 is provided in the roller 21, the housing 11 is inserted into the roller 21 from the insertion port 211 and the output shaft 12 is drivingly connected to the connecting portion 212, the second end of the roller 21 is installed with a support shaft 213, the roller 21 is coaxially arranged with the support shaft 213, the end assembly component 22 is rotatably connected to the support shaft 213, the end assembly component 22 is detachably connected to the body 30 of the cleaning robot, and the brush cover 23 is sleeved on the roller 21.

The roller brush device of the present application integrates a driving mechanism 10 and a roller brush structure 20. After the first end of the driving mechanism 10 is installed on the body 30 of the cleaning robot, it can rotate relative to the body 30 of the cleaning robot, so that the second end of the driving mechanism 10 forms a free end, and the roller brush structure 20 can be detached from the driving mechanism 10 for replacement. When the roller brush structure 20 is installed on the body 30 of the cleaning robot, it is only necessary to put the roller 21 of the roller brush structure 20 on the driving mechanism 10, so that the output shaft 12 of the driving mechanism 10 and the connecting part 212 of the roller 21 can be connected, and then the driving mechanism 10 is rotated so that the end assembly component 22 installed on the roller 21 can be connected to the body 30 of the cleaning robot, so that the installation of the roller brush structure 20 is completed. In this way, the output shaft 12 drives the roller 21 to rotate, so that the brush cover 23 of the roller brush structure 20 rotates with the roller 21 to clean the floor. When the roller brush structure 20 needs to be replaced, the end assembly component 22 is first unlocked and detached from the body 30 of the cleaning robot, and the first end of the driving mechanism 10 is rotated to make the roller brush structure 20 detach from the body 30 of the cleaning robot, and then the roller brush structure 20 is directly pulled out from the driving mechanism 10. The roller brush device of the present application is applied to the cleaning robot, so that the roller brush structure 20 can be easily and quickly disassembled and replaced, and the disassembly and assembly efficiency is significantly improved, which improves the user experience.

As shown in Figures 6 and 7, the second end of the drum 21 is fixedly installed with an anti-slip member 214, and a through hole 2141 is provided in the middle of the anti-slip member 214, and the support shaft 213 passes through the through hole 2141. As shown in Figures 8 to 10, the end assembly component 22 includes a body 221 and a support cover 222, and the support cover 222 is fixedly installed on the body 221, and a plurality of hooks 2221 are provided on the side of the support cover 222 away from the body 221. The hook 2221 passes through the through hole 2141 and is hooked on the anti-slip member 214 to prevent the end assembly component 22 from detaching from the drum 21, and the hook 2221 is located in the through hole 2141 so that the end assembly component 22 can rotate relative to the drum 21 as a whole, that is, the support shaft 213 passes through the space surrounded by the plurality of hooks 2221 and is rotatably connected to the body 221 through the copper sleeve 223, and the body 221 is used to be detachably connected to the body 30 of the cleaning robot. In this way, after the roller brush structure 20 is mounted on the driving mechanism 10 and connected to the body 30 of the cleaning robot through the main body 221, the roller 21 can be driven to rotate by the driving mechanism 10, thereby performing a cleaning operation on the floor.

Furthermore, the cooperation between the anti-slip component 214 and the plurality of hooks 2221 can reduce the gap between the through hole 2141 and the outside, thereby effectively reducing the probability of hair and debris on the ground entering into contact with the support shaft 213, and effectively reducing the frequency of the support shaft 213 being entangled by hair.

As shown in Fig. 8 and Fig. 10, the main body 221 is provided with a first clamping portion 2211, and the first clamping portion 2211 is used to clamp to the second clamping portion (not shown) of the body 30 of the cleaning robot. After the roller 21 is mounted on the driving mechanism 10, the roller brush structure 20 and the driving mechanism 10 are rotated toward the body 30 as a whole with the first end of the driving mechanism 10 as a fulcrum, so that the end assembly component 22 is close to the body 30, and the first clamping portion 2211 of the end assembly component 22 corresponds to the second clamping portion of the body 30. After the end assembly component 22 moves to the connection position between it and the body 30, the end assembly component 22 is rotated forward relative to the roller 21 as a whole, so that the first clamping portion 2211 and the second clamping portion are clamped and installed, and the entire installation work of the roller brush structure 20 is completed, and the installation work is convenient, simple, fast, and efficient.

When the roller brush structure 20 needs to be removed, the end assembly component 22 is first rotated in the opposite direction to unlock the first clamping portion 2211 and the second clamping portion, and then the roller brush structure 20 and the driving mechanism 10 are rotated together as a whole away from the body 30 with the first end of the driving mechanism 10 as a fulcrum until the roller brush structure 20 can be removed from the driving mechanism 10. Therefore, the roller brush device of the present application is not only convenient, simple, and fast to install, but also convenient, simple, and fast to disassemble, and has high installation efficiency.

In order to enable the end assembly component 22 to quickly and accurately move to the connection position between it and the fuselage 30 when the roller brush structure 20 and the driving mechanism 10 are rotated toward the fuselage 30 as a whole with the first end of the driving mechanism 10 as a fulcrum, as shown in Figures 8 to 10, the main body 221 is provided with a positioning groove 2212, and the positioning groove 2212 is used to be assembled with the positioning rib (not shown) of the fuselage 30 of the cleaning robot. That is to say, when the roller brush structure 20 and the driving mechanism 10 are rotated toward the fuselage 30 as a whole with the first end of the driving mechanism 10 as a fulcrum, so that the positioning groove 2212 of the main body 221 is aligned with the positioning rib of the fuselage 30, the positioning function and the guiding function are realized between the positioning groove 2212 and the positioning rib, so that the end assembly component 22 can quickly and accurately move to the connection position between it and the fuselage 30. Furthermore, the positioning groove 2212 is an arc-shaped groove surrounding the rotation axis of the main body 221. Therefore, when the end assembly component 22 rotates relative to the drum 21 so that the first clamping portion 2211 and the second clamping portion are clamped together, no movement interference will occur between the positioning groove 2212 and the positioning rib, so that the end assembly component 22 can rotate smoothly relative to the drum 21 until the first clamping portion 2211 and the second clamping portion are clamped together.

When the cleaning robot is running and the driving mechanism 10 drives the roller brush structure 20 to rotate relative to the body 30, the roller brush structure 20 is inevitably affected by vibration, which easily causes the end assembly component 22 to rotate in the opposite direction by itself, resulting in the first clamping portion 2211 being unlocked from the second clamping portion, and then causing the roller brush structure 20 to be separated from the body 30 and unable to perform cleaning operations stably. Therefore, as shown in Figures 8 to 10, the main body 221 is also provided with a spring buckle 2213, which is used to be clamped to the third clamping portion (not shown) of the body 30 of the cleaning robot. In this way, the spring buckle 2213 and the third clamping portion can play a limiting role, thereby limiting the end assembly component 22 from rotating in the opposite direction by itself. Only after the spring buckle 2213 and the third clamping portion are manually unlocked, the end assembly component 22 can rotate in the opposite direction relative to the body 30, and then the first clamping portion 2211 is unlocked from the second clamping portion, and then the roller brush structure 20 is extracted from the driving mechanism 10.

8 to 10 , in order to facilitate the staff to operate the end assembly assembly 22 to rotate relative to the drum 21 , an operating handle 2214 is provided. The staff can rotate the end assembly assembly 22 by holding the operating handle 2214 .

As shown in FIGS. 4 to 6 , at least one supporting member 13 is provided on the outer wall of the housing 11, so that when the drum 21 is mounted on the housing 11 of the driving mechanism 10, the supporting member 13 supports the drum 21, so that the drum 21 can be more stable relative to the housing 11. Specifically, the supporting member 13 includes a bearing 131 and a soft supporting portion 132, and the soft supporting portion 132 is mounted on the outer wall of the housing 11 through the bearing 131, and the soft supporting portion 132 abuts against the inner wall of the drum 21 when the housing 11 is inserted into the drum 21. In addition, during the operation of the cleaning robot, when the roller brush structure 20 passes over a slightly raised obstacle on the ground, the roller brush structure 20 will squeeze the soft supporting portion 132, so that the soft supporting portion 132 is compressed and deformed to achieve buffering, thereby avoiding the drum 21 from directly squeezing and colliding with the housing 11 of the driving mechanism 10, thereby better protecting the driving mechanism 10.

Furthermore, in the embodiment of the present application, a support member 13 is provided at the second end of the housing 11. The support member 13 is close to the insertion port 211 when the housing 11 is inserted into the drum 21, and the soft support portion 132 of the support member 13 is used to block the insertion port 211. In this way, the gap between the insertion port 211 of the drum 21 and the housing 11 is blocked by the soft support portion 132 of the support member 13. Therefore, when the roller brush structure 20 cleans the floor, hair, debris, garbage, etc. on the ground cannot be rolled between the drum 21 and the housing 11, which reduces the probability of the drum 21 being unable to rotate due to the influence of foreign matter between the drum 21 and the driving mechanism 10, and better protects the roller brush structure 20.

As shown in FIG. 4 and FIG. 5 , two mounting posts 14 are provided at the first end of the housing 11. The two mounting posts 14 extend in opposite directions, that is, the central axes of the two mounting posts 14 are in the same straight line (coaxial arrangement). The first end of the housing 11 is mounted to the body 30 of the cleaning robot through the two mounting posts 14, so that the roller brush device can be rotated as a whole with the two mounting posts 14 as rotation supports and rotate around the central axis of the mounting posts 14, so that the roller brush structure 20 can be removed from the driving mechanism 10 after being away from the body 30.

As shown in FIGS. 1 to 6 , the roller brush device further includes a pressure cover 24, which is used to be connected to the body 30 of the cleaning robot to limit the maximum angle at which the first end of the housing 11 can flip relative to the body 30 of the cleaning robot. The pressure cover 24 not only restricts the two mounting posts 14 from being separated from the body 30, but also limits the rotation angle of the first end of the housing 11 around the central axis of the mounting post 14, the specific rotation angle being about 15°, and the roller brush structure 20 can be smoothly removed from the driving mechanism 10.

According to another aspect of the present application, a cleaning robot is provided. Specifically, the cleaning robot comprises a body 30 and the aforementioned roller brush device, wherein the body 30 is provided with a receiving space 31 , and the roller brush device is located in the receiving space 31 .

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.
