As one kind of service robot, the cleaning robot mentioned in the present application is different from a small cleaning robot used for household use, and refers to a usage scenario suitable for public areas like residential buildings and large open areas such as office buildings, hotels, hospitals, etc., and compared with residential rooms, in public areas of residential buildings and places such as office buildings, hotels, hospitals, etc., firstly, the working area is wider, the endurance requirement for the cleaning robot is higher, obviously, the small cleaning robot is difficult to satisfy, secondly, the types of garbage to be cleaned are more diverse, the quantity is more, and the requirement for the processing capacity of the cleaning robot is higher.

The core of the cleaning robot lies in various working components which are respectively applied to treating different types of garbage, and the cleaning robot generally comprises a mopping component and a cleaning component, wherein the mopping component is usually arranged at the tail end of the cleaning robot, the cleaning component is usually arranged at the front end of the cleaning robot, in the working process, the cleaning component cleans the ground, dust, garbage and the like are swept to a dust suction port of a dust suction device, the dust suction device absorbs and temporarily stores the dust, the garbage and the like, and the mopping component further cleans the ground and simultaneously adsorbs and removes residual moisture on the ground. The core working component of the mopping component is a mopping piece which is mostly made of cloth materials, for example, rags are used, and the cleaning robot drives the mopping piece to move, so that the mopping and cleaning of the ground are realized.

As is known, a cleaning robot mainly includes a machine body, a traveling mechanism for driving the machine body to travel and transfer a cleaning position, a cleaning mechanism for cleaning and collecting garbage, and a dust suction mechanism for sucking the garbage collected by the cleaning mechanism into a garbage collection tank. The brush disc mechanism is a part of the cleaning mechanism and is of a disc-shaped brush structure, and the brush disc of the traditional cleaning robot is rotatably connected onto the machine body. The inventors have found that such an arrangement has a number of disadvantages.

Firstly, clean the scope limited, unable comprehensive coverage, for example, when cleaning the wall limit, owing to need avoid brush dish and wall to bump, need reserve sufficient clearance between brush dish and wall, this just leads to being close to the place on wall limit unable clean or clean the effect limited.

Secondly, the brush disc is easy to be damaged, the use cost is increased, and the position of the brush disc relative to the machine body cannot be changed, so that the brush disc is difficult to be ensured not to collide with other objects in a complex use scene, and the brush disc is easy to be damaged by collision.

In summary, in view of the problems in the prior art, the inventors propose a brush disc mechanism having a link mechanism by which a brush disc is mounted on a robot body, the link mechanism having a retracting function capable of retracting the brush disc when the brush disc collides with the outside.

As shown in fig. 1 and 2, fig. 1 is a structural view of a cleaning robot to which a brush tray mechanism is applied according to some embodiments of the present disclosure, and fig. 2 is a structural view of a link mechanism according to some embodiments of the present disclosure; the application provides a brush dish mechanism is applied to cleaning machines people, including at least one brush dish subassembly 10, brush dish subassembly 10 includes:

The elastic member 122 is compressed when the first link 111 and the third link 113 rotate, so that the first link 111 and the third link 113 are prevented from rotating too fast to collide with the robot body 1, and the first link 111 and the third link 113 are buffered to convert kinetic energy of the first link 111 and the third link 113 into elastic potential energy, and after the external limitation disappears, the brush tray 110 is restored under the elastic restoring force of the elastic member 122.

Obviously, the single rod structure that directly arranges the brush disk 110 on the first connecting rod 111 or the third connecting rod 113 can also achieve the purpose of retracting the brush disk 110 to protect the brush disk 110 from being damaged, however, the connecting rod mechanism in the present application can achieve the above purpose, and at the same time, compared with the above single rod structure, the connecting rod mechanism can bear larger moment in the horizontal direction, thereby increasing the connection strength between the brush disk 110 and the robot body 1, and improving the stability of the brush disk 110 during the rotation of the brush disk 110.

Furthermore, the above-mentioned single rod structure is easy to cause the phenomenon of collision between the brush disc 110 and the robot body 1 during rotation, and is not paid from the perspective of protecting the brush disc 110, and the link mechanism of the present application not only draws close to the robot body 1 during the movement of the brush disc 110, but also includes the process of moving to the rear of the robot body 1, and compared with the simple rotation retraction, the distance of the brush disc 110 moving to the robot body 1 is less, thereby avoiding the phenomenon of collision between the brush disc 110 and the robot body 1.
