Mobile mechanism and mobile robot having same, and mobile method

A mobile robot, comprising a mobile mechanism, comprising:

• a housing in which a guide portion is provided;
• a sliding seat mounted on the guide portion and movable along the guide portion;
• a moving wheel fixed on the sliding seat and partially protruding beyond a surface of the housing;
• a pressing portion pressing against the sliding seat and moving the sliding seat toward the surface of the housing;
• and
• a deformation portion mounted on the housing and connected with the pressing portion, the deformation portion causing the pressing portion to rotate about a rotating shaft coupled to the housing and generating a force by the pressing portion, to force the sliding seat to descend, pushing the moving wheel out of the housing, and keeping the moving wheel in contact with a working surface,
• wherein the mobile robot is a cleaning robot or a mowing robot, and
• wherein a first longitudinal axis of the guide portion and a second longitudinal axis of the deformation portion are not co-located.

A method for moving a mobile robot, wherein the mobile robot comprises a moving wheel in contact with a working surface, a pressing portion, a guide portion, a deformation portion, and a sliding seat movably connected with a main body comprising an upper housing and a lower housing, the method comprising:

• when moving, lowering a height of the main body from the working surface, such that the sliding seat is in a rising posture on the guide portion;
• when the sliding seat is in the rising posture, pushing up the pressing portion to cause deformation of the deformation portion;
• and
• when the deformation portion is deformed, causing the pressing portion to rotate about a rotating shaft coupled to the main body and generating a force by the pressing portion, to force the sliding seat to descend, pushing the moving wheel out of the lower housing, and keeping the moving wheel in contact with the working surface,
• wherein a first longitudinal axis of the guide portion and a second longitudinal axis of the deformation portion are not co-located.
