Lead screw assembly is in on-position, and absorbent module is in decline state, smaller with wall surface gap, provides reliable wall for robot
Face adsorption capacity.When robot encounters obstacle, the lead screw assembly on corresponding vehicle frame brings into operation, and spindle motor drives A type belt wheel
Rotation drives belt operation, and then drives the rotation of Type B belt wheel, since Type B belt wheel and feed screw nut circumferential movement are relatively fixed,
Feed screw nut carries out same rotary motion, since the movement of feed screw nut axial direction has been fixed, lead screw is driven to be promoted,
After the promotion for driving absorbent module progress certain altitude by lead screw again, spindle motor braking, the suction that lead screw is driven at the same time
Electromagnet reversely magnetizes inside the absorbent module that attached component is driven, and offsets a part one kind, two class permanent magnets relative to wall surface
Adsorption capacity, electromagnet forward direction magnetizes inside the absorbent module that is not driven, with required wall surface during ensuring robot operation
Adsorption capacity, multiple groups adsorption module are used in conjunction with each other.After the corresponding vehicle frame of one group of adsorption module passes through obstacle, spindle motor is anti-
To operation, absorbent module is driven to drop to specified altitude assignment, electromagnet is out of service, completes the obstacle detouring process of this group of vehicle frame.
The present embodiment is implemented under the premise of the technical scheme of the present invention, gives detailed embodiment and specific
Operating process, but protection scope of the present invention is not limited to the above embodiments.
