Sweeping robot resetting mechanism and sweeping robot

The utility model relates to a sweeping robot reset mechanism and a sweeping robot, the sweeping robot reset mechanism comprises at least one collision assembly and at least one guide assembly, and a reset top block in the collision assembly is configured to be capable of responding to the acting force of an extrusion plate to generate relative motion with the extrusion plate; a guide groove is formed in a guide part in the guide assembly, at least part of a guide column is contained in the guide groove, and one of the guide part and the guide column is configured to move relative to the other one of the guide part and the guide column along with a reset ejector block. By the adoption of the sweeping robot reset mechanism, after collision is finished, the guide part or the guide column can return to the original position along with the reset ejector block, the reset ejector block can accurately return under the guiding effect of the guide groove, and the sweeping robot reset mechanism is simple in overall str
