As shown in fig. 1 to 7, the present embodiment provides a cleaning robot, which includes a main body 1 and functional modules, such as a cleaning module, a power module, a transmission module, and the like, disposed on the main body 1. The body 1 forms an overall appearance of the cleaning robot. The body 1 comprises a housing cavity 11 for mounting the functional modules therein. Part of the functional modules (such as cleaning modules) extend out from the bottom of the body 1 so as to clean and care the surface to be cleaned or the object to be cleaned. The accommodating chamber 11 includes a chamber opening 111, so that a cleaning person can conveniently extend into the accommodating chamber 11 through the chamber opening 111 to repair and replace corresponding parts or perform operations such as adding cleaning liquid.

The cleaning robot further includes an opening and closing door 3 rotatable with respect to the body 1 to open or close the cavity opening 111 of the receiving cavity 11. For example, during the cleaning task performed by the cleaning robot, the opening and closing door 3 closes the cavity opening 111 of the accommodating cavity 11, so as to protect each functional module in the main body 1, and the whole device is safer and more beautiful. When the cleaning robot does not perform a cleaning task, a certain component is out of order, or cleaning liquid needs to be added, the opening and closing door 3 is rotated to open the cavity opening 111.

In this embodiment, the cavity 111 is opened at the front side of the body 1 (i.e. the side of the body 1 close to the advancing end), and the corresponding switch door 3 is disposed opposite to the cavity 111 and connected to the front side of the body 1. When the opening/closing door 3 is rotated upward, the chamber opening 111 is opened. When the opening and closing door 3 is rotated downward, the chamber opening 111 is closed. The traveling end refers to an end of the cleaning robot facing a traveling direction during movement. In other embodiments, the cavity 111 and the opening/closing door 3 may be opened at the rear side, the left side or the right side of the body 1. In other embodiments, the opening and closing door 3 may be rotated downward to open the cavity 111, or the opening and closing door 3 may be rotated leftward/rightward to open the cavity 111.

For convenience of subsequent description, the rotation direction of the switch door 3 away from the body 1 to open the cavity 111 is set as a first direction, and the rotation direction of the switch door 3 close to the body 1 to close the cavity 111 is set as a second direction. The opening and closing door 3 has two extreme states of being fully opened and fully closed. When the opening and closing door 3 is fully opened, the opening and closing door 3 is opened to its maximum rotation angle with respect to the body 1. When the opening/closing door 3 is completely closed, the chamber opening 111 is completely closed. The switching door 3 has a first extreme position and a second extreme position corresponding to the two extreme states. When the door 3 is located at the first limit position, the door 3 is opened to its maximum rotation angle relative to the body 1, and at this time, the door 3 cannot rotate relative to the body 1 in the first direction. In the second limit position, the opening/closing door 3 completely closes the cavity opening 111, and the opening/closing door 3 cannot rotate relative to the body 1 in the second direction.

The cleaning robot further comprises a swivel connection 4, a mounting 2 and a telescopic element 5. The mounting member 2 is provided on the body 1. The mounting member 2 serves as a mounting carrier for the swivel joint 4. The rotary connection 4 is rotatably mounted on the mounting member 2. The rotary connecting piece 4 is connected with the switch door 3. The two ends of the telescopic piece 5 are respectively connected with the rotary connecting piece 4 and the body 1. The telescopic member 5 illustratively comprises a gas spring, a hydraulic push rod or an electric push rod. Taking the example where the expansion member 5 comprises a gas spring, the expansion member 5 comprises a cylinder 51 and a piston rod 52. In this embodiment, the cylinder 51 is rotatably connected to the body 1, and the extending end of the piston rod 52 is rotatably connected to the rotary connector 4. In other embodiments, the cylinder 51 may be rotatably connected to the rotary connector 4, and the extending end of the piston rod 52 may be connected to the body 1.

Manual rotation opens or closes switch door 3, and switch door 3 drives and rotates connecting piece 4 and rotates for installed part 2, rotates connecting piece 4 and further drives extensible member 5 and rotates for body 1, and the piston rod 52 of extensible member 5 is retrieved or is stretched out for cylinder body 51 simultaneously. Alternatively, the extensible member 5 may be an active member, and the cleaning robot further includes a controller capable of controlling the extension and contraction of the piston rod 52 with respect to the cylinder 51. The controller controls the piston rod 52 to automatically extend and retract, the piston rod 52 drives the rotary connecting piece 4 to rotate relative to the mounting piece 2, and the rotary connecting piece 4 further drives the switch door 3 to rotate so as to open or close the cavity opening 111. That is to say, the switch door 3 of this embodiment can be opened manually or opened automatically, and overall structure is simple, convenient operation, and product cost is low.

In one embodiment, when the piston rod 52 of the telescopic member 5 extends relative to the cylinder 51, the piston rod 52 can stop at any position in the stroke, so that the piston rod 52 provides a certain supporting force for the opening and closing door 3 through the rotating connecting member 4, and the opening and closing door 3 stays at any position between the first limit position and the second limit position. According to the position of a specific part to be maintained or replaced in the accommodating cavity 11 or the space around the cleaning robot, the switch door 3 can be manually rotated to be opened or closed to any position between the first limit position and the second limit position, or the controller controls the stroke of the piston rod 52, so that the switch door 3 is rotated to be opened or closed to any position between the first limit position and the second limit position, the telescopic piece 5 supports the switch door 3 to stably stay at the corresponding position, the manpower or mechanical power consumption is saved, and meanwhile, the switch door 3 is prevented from interfering with surrounding objects when being opened.
