Wherein, the collision plate 12 is used for preventing the cleaning robot from colliding with the obstacle, and the collision plate 12 is arranged at the front end of the body 1; the navigation component 13 is used for map scanning to realize map building and positioning of the cleaning robot, and the navigation component 13 is arranged above the body 1; the battery 7 is used for supplying electric energy to the cleaning robot; the control device is used for controlling various activities of the cleaning robot, such as sensor signal collection, motor drive control, battery 7 management, navigation positioning, map generation, intelligent obstacle avoidance, cleaning path planning and the like. In order to facilitate the obstacle crossing of the cleaning robot, the cleaning robot further comprises a lifting mechanism. The cleaning robot in this embodiment is D-shaped in appearance, wherein the circular end is used as the forward direction and is the front of the cleaning robot, the collision plate 12 is arranged in front of the body 1, and the bottom layout comprises a first driving assembly 2, a second driving assembly, a third driving assembly, an edge brush 3, at least two dragging pieces and the like. The front end of the cleaning robot is set to be arc-shaped, so that the cleaning robot is easier to turn after colliding with an obstacle compared with the linear collision plate 12. When the at least two mopping pieces are positioned at the rear part of the cleaning robot, the rotation center and the rotation diameter of the whole cleaning robot do not change greatly relative to the original D-shaped rotation center, so that the turning radius is smaller when the whole cleaning robot runs and turns, the difficulty escaping aspect and the coverage rate aspect can be improved, and the rotation center of the whole cleaning robot is the center of an circumscribed circle with a D-shaped outline.

In some embodiments of the present invention, the cleaning robot is easy to be stuck when encountering a protrusion during the forward or backward movement of the cleaning robot, and in order to enable the cleaning robot to smoothly pass over, the edge of the side of the body 1 facing the floor or other household surface is provided with an upward inclined slope, and when encountering a protrusion or a sudden height change, the cleaning robot is guided to pass over the protrusion or the sudden change region through slope transition.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
