[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0045] In the related art, a roller brush is usually used to clean the pavement in the courtyard. The roller brush is generally handheld or ride-on. No matter which roller brush is used, the user needs to use it outdoors. When used in severe weather (snowstorms, rainstorms), the user is prone to danger due to the influence of severe weather.

[0046] In view of this, the applicant conducted in-depth research on how to solve the technical problem of how to prevent users from using roller brush tools in harsh environments in the related art, so as to form the technical solution of the present application.

[0047] See also Figures 1 to 4 , an embodiment of the utility model proposes an autonomous cleaning robot applied to a courtyard, comprising:

[0048] A self-mobile device 10 having a front end and a back end;

[0049] The first snow removal device 20 installed on the self-moving device 10 includes:

[0050] a housing 21, wherein the housing 21 defines an inlet and a cavity 211 communicating with the inlet; and

[0051] The roller brush assembly 22 includes a roller brush body 221 rotatably disposed in the housing 21 , and the lower end of the roller brush body 221 rotates from the rear end to the front end.

[0052] The self-moving device 10 may be a body with a front end and a rear end, and may be equipped with components such as motors and wheels to achieve autonomous movement and navigation in a courtyard.

[0053] The mobile function can be realized by adopting a crawler walking mechanism or a four-drive wheel mechanism.

[0054] The first snow removal device 20 is installed on the self-moving device 10 and includes a shell 21 and a roller brush assembly 22 .

[0055] The shell 21 is provided with an inlet, which defines the inlet and a cavity 211 connected to the inlet, so as to ensure that the internal components are effectively protected under extreme weather conditions.

[0056] The roller brush assembly 22 includes a roller brush body 221 rotatably disposed in the housing 21 , and the lower end of the roller brush body 221 rotates from the rear end to the front end of the robot to ensure thorough cleaning of the courtyard pavement.

[0057] In this embodiment, the user controls a mobile device equipped with an autonomous cleaning robot to place the robot in an area of ​​the courtyard that needs to be cleaned.

[0058] After the robot is started, it uses the navigation system of the autonomous mobile device to intelligently plan the most effective cleaning path to cover the entire courtyard.

[0059] The roller brush assembly 22 is responsible for removing debris, snow and the like from the courtyard road surface, and its rotatable design can efficiently achieve road surface cleaning.

[0060] Users can start, stop or adjust the robot's cleaning operation at any time through the remote control or preset program on the autonomous mobile device.

[0061] This embodiment has the following effects: on the one hand, it can improve the safety of users when cleaning courtyard roads outdoors, and avoid the dangers that users may face when using traditional roller brush tools in bad weather.

[0062] Users do not need to sweep the snow themselves. They can use remote control or preset programs to achieve unmanned cleaning of the yard, reducing the user's physical labor.

[0063] Secondly, the robot can adapt to different courtyard environments, providing a convenient and efficient cleaning solution.

[0064] That is to say, through the cooperation of the self-moving device 10 and the roller brush assembly 22, the safety problem of outdoor cleaning under severe weather conditions is effectively solved, and the user's outdoor zero-involvement, fully autonomous yard cleaning experience is achieved.

[0065] In some embodiments, the roller brush assembly 22 further includes:

[0066] The roller brush body 221 is fixed to the rotating shaft installed in the housing 21 to rotate along with the rotating shaft.

[0067] The rotating shaft is installed in the housing 21 and serves as a support and rotation center of the roller brush body 221 .

[0068] The roller brush body 221 is fixed to the rotating shaft to rotate along with the rotating shaft, thereby achieving a more flexible cleaning operation.

[0069] It can be understood that the rotation mechanism of the rotating shaft allows the roller brush body 221 to rotate more smoothly, effectively clearing debris and snow on the courtyard road surface, thereby improving the cleaning efficiency.

[0070] The rotating shaft can serve as a support center, can disperse the rotational force of the roller brush body 221, reduce the wear of the robot and the courtyard pavement, and extend the service life of the robot.

[0071] In some embodiments, the roller brush body 221 extends in a vertical direction, or the roller brush body 221 extends in a direction from one end of the rotating shaft to the other end and from top to bottom.

[0072] The roller brush body 221 extends in the vertical direction, making the cleaning ability more comprehensive. This design allows the roller brush to more effectively contact and clean debris and snow on the ground, ensuring a wider range of cleaning heights, and improving the adaptability of the robot in different scenarios.

[0073] The roller brush body 221 extends from one end of the rotation axis to the other end and from top to bottom, which helps to ensure that the roller brush body 221 is always close to the ground during the entire cleaning process, thereby increasing the cleaning effect. This design is suitable for handling obstacles of different heights and shapes, such as steps or uneven terrain.

[0074] That is to say, the design extending in the vertical direction or from top to bottom enables the roller brush body 221 to cover the ground more comprehensively when rotating, thereby improving the cleaning efficiency and ensuring that the courtyard pavement is thoroughly cleaned.

[0075] In some embodiments, the roller brush body 221 includes a first body and a second body, the first body is installed on the left side of the rotating shaft, and the second body is installed on the right side of the rotating shaft;

[0076] The first body extends from the center of the rotating shaft toward the left end and from top to bottom, and the second body extends from the center of the rotating shaft toward the right end and from top to bottom.

[0077] First, the separation design of the first body and the second body enables the roller brush assembly 22 to have a larger coverage area, thereby improving the cleaning efficiency. This design can adapt to roads of different widths, ensuring that a wider area is covered during one cleaning process.

[0078] Furthermore, the first body and the second body extend along the center of the rotating shaft toward the left and right ends, achieving a left-right symmetrical cleaning effect. This helps the robot to balance the cleaning load when moving and provide a uniform cleaning result.

[0079] It is worth mentioning that the first body located on the left side can move the snow and debris to the left side, and the second body located on the right side can move the snow and debris to the right side, which can greatly improve the cleaning efficiency and cleaning performance of the roller brush.

[0080] In some embodiments, a bracket 30 is further included, and the bracket 30 is installed on the self-moving device 10, and the shell 21 is installed on the bracket 30 so as to be rotatable in the left-right direction.

[0081] The bracket 30 can provide a stable structure to ensure that the roller brush assembly 22 can remain stable during the cleaning operation, thereby improving the stability of the entire autonomous cleaning robot.

[0082] It is understandable that the housing 21 is rotatably mounted on the bracket 30 in the left-right direction, achieving adjustable rotation in the left-right direction. This design allows the robot to adapt to the courtyard environment more flexibly and ensures a wider coverage of cleaning.

[0083] On the other hand, the design of the housing 21 that rotates left and right enables the robot to better avoid obstacles during the cleaning process, optimize the cleaning path, and improve the cleaning efficiency.

[0084] In some embodiments, the bracket 30 is provided with an electric push rod 40, and the electric push rod 40 is transmission-connected to the housing 21 to drive the housing 21 to rotate in the left-right direction.

[0085] The housing 21 is electrically driven by the transmission connection of the electric push rod 40. This design enables the robot to achieve more intelligent and accurate left and right rotation during the cleaning operation, so that the roller brush assembly can be driven to rotate to the left or right to move the snow or debris to the side, so as to ensure that there is no excessive snow on the path of the self-moving device.

[0086] The electric push rod 40 is transmission-connected to the housing 21, and can achieve more precise left-right rotation, optimize the cleaning path, and ensure that the robot can cover a wider area during the cleaning process.

[0087] Moreover, the transmission mechanism of the electric push rod 40 can realize the function of automatically adjusting the direction of the shell 21, so that the robot can automatically adjust the cleaning path according to environmental obstacles during movement, thereby improving the cleaning efficiency.

[0088] In some embodiments, the electric push rod 40 is tilted in a horizontal direction from one end of the rotating shaft to the other end.

[0089] The horizontal tilt setting of the electric push rod 40 means that there is an angle in the horizontal direction, so that the robot can more flexibly adapt to different terrains, such as slopes or uneven roads, during cleaning operations.

[0090] The horizontal tilt design allows the robot to automatically adjust the cleaning angle according to different terrains during cleaning, better adapt to the environment and improve cleaning efficiency.

[0091] Furthermore, the horizontally inclined design helps ensure that the roller brush assembly 22 is in closer contact with the ground, thereby increasing the cleaning effect, especially on uneven terrain.

[0092] In some embodiments, a driving mechanism 60 is also included, and the driving mechanism 60 includes a motor installed on the housing 21, a reduction gear box transmission-connected to the motor, a pulley transmission-connected to the reduction gear box, and a turbine worm structure transmission-connected to the pulley, and the worm gear structure is transmission-connected to the rotating shaft to drive the rotating shaft to rotate.

[0093] Among them, the driving mechanism 60 uses a motor as a power source, which provides a strong driving force to ensure that the robot can operate efficiently and stably during the cleaning operation.

[0094] Among them, the reduction box is used to reduce the speed of the motor output, increase the driving torque, and ensure that the robot has sufficient power when rotating the shaft to adapt to various yard cleaning tasks.

[0095] The pulley connects the motor and the worm gear structure through transmission to achieve energy transmission. This design makes the rotation of the shaft more stable, reduces energy loss, and improves the overall efficiency of the robot.

[0096] Among them, the worm gear structure provides additional transmission force, enhances the rotation force of the robot, and ensures that the roller brush assembly 22 can effectively clean the courtyard pavement.

[0097] In this way, a reliable transmission connection can be achieved. The transmission connection between the worm gear structure and the rotating shaft enables the robot to reliably drive the roller brush assembly 22 to rotate during the cleaning operation, ensuring a more stable and uniform cleaning effect.

[0098] Then, the autonomous cleaning robot has more powerful power and stable rotation performance in yard cleaning, which improves the overall cleaning effect and reliability.

[0099] In some embodiments, a support assembly 50 is further included which is mounted on the housing 21. The support assembly 50 includes:

[0100] Wheel frame 51;

[0101] A supporting wheel 53, wherein the supporting wheel 53 is mounted on the wheel frame 51; and

[0102] The elastic member 52 is disposed between the wheel frame 51 and the supporting wheel 52 .

[0103] In some embodiments, the first snow removal device 20 is detachably connected to the self-moving device 10;

[0104] The autonomous cleaning robot further comprises a second snow removal device 70 detachably connected to the autonomous moving device 10 , wherein the second snow removal device 70 is a snow throwing device;

The first snow removal device 20 is suitable for clearing debris and snow on the courtyard road surface, while the second snow removal device 70 is a snow throwing device for handling a large amount of snow.

[0107] It is worth noting that the autonomous cleaning robot has a first mode and a second mode. In the first mode, the robot uses the first snow removal device 20, which is suitable for general yard cleaning tasks; while in the second mode, the robot switches to the second snow removal device 70 for handling more serious snow accumulation.

[0108] The design of the first and second modes enables the robot to adapt to the snow removal needs of different seasons, providing users with a year-round cleaning solution. Users can choose the appropriate working mode according to specific weather and snow removal needs, which improves the flexibility and convenience of the robot.

[0109] In some embodiments, the first snow removal device 20 is detachably connected to the self-moving device 10;
