Abstract:
An apparatus for climbing obstacles, and a cleaning apparatus. The apparatus for climbing obstacles comprises: a first linkage mechanism (11), used for movable connection to a housing (20); and an obstacle climbing assembly (12), one end thereof being movably connected to the linkage mechanism (11), and the another opposite end being used to press on an obstacle so as to lift the housing (20). The cleaning apparatus comprises the housing (20); movement wheels (21); a driving component (22), mounted in the housing (20) and connected to the movement wheels (21) so as to drive the movement wheels (21) to move; and a support component (111), connected to the housing (20), and the obstacle climbing assembly (12) being connected to the driving component (22). The linkage mechanism (11) is movably connected on on end of the obstacle climbing assembly (12) so as to cause the obstacle climbing assembly (12) to have a greater movement space during movement under the guidance of the linkage mechanism (11), thus being able to raise the housing (20) to a higher height, and thereby improving obstacle climbing reliability.
