Synchronous cleaning brush assembly and cleaning robot

The utility model relates to the technical field of cleaning brush assemblies, and provides a synchronous cleaning brush assembly and a cleaning robot. At least two cleaning brushes; the synchronizing mechanism is connected with the at least two cleaning brushes; the lifting driving mechanism is respectively connected with the base frame and the synchronizing mechanism so as to drive the synchronizing mechanism to do lifting motion relative to the base frame; the rolling friction mechanisms are arranged between the synchronizing mechanism and the base frame, the number of the rolling friction mechanisms is the same as that of the at least two cleaning brushes, and the positions of the rolling friction mechanisms correspond to the positions of the cleaning brushes; when the synchronous mechanism is driven by the lifting driving mechanism, the rolling friction mechanism is matched with the base frame in a rolling friction mode, the synchronous cleaning brush assembly can enable all the cleaning brushes (such as
