two brushless electric machine driving wheels between difference in height be brushless electric machine driving wheel diameter 1/2, therefore, being arranged in each sub-walking mechanism front, its lower surface forefront brushless electric machine driving wheel along sweeping robot body 1 direction of travel can with the movement of sweeping robot, first move to the upper surface of barrier, due to distance measuring sensor 5 real-time working in each sub-walking mechanism, obtain range measurement and be uploaded in the single-chip microcomputer be attached thereto, then now, along sweeping robot direction of travel, the range measurement being positioned at the distance measuring sensor 5 in bar 2 front, poor position in this each sub-walking mechanism can correspondingly diminish, namely in this each sub-walking mechanism single-chip microcomputer obtain and will strain greatly mutually from the difference in height be attached thereto between two distance measuring sensor 5 range measurement, be greater than elemental height difference, single-chip microcomputer then in this each sub-walking mechanism controls the brushless rotary motor work be attached thereto immediately, difference position bar 2 in this each sub-walking mechanism is rotated under the control of corresponding brushless rotary motor, one end of the corresponding sweeping robot direction of travel of lower pressure reduction position bar 2, namely the front end of pressure reduction position bar 2 is descended, brushless electric machine driving wheel on this end is contacted with the upper surface of barrier, like this, in this each sub-walking mechanism, two brushless electric machine driving wheels at front and rear move respectively on blocking surfaces and floor surface, the rear brushless electric machine driving wheel jointly had an effect in the sub-walking mechanism of drive this each moves on blocking surfaces, continue to move along sweeping robot direction of travel, rear brushless electric machine driving wheel in this each sub-walking mechanism moves to after on blocking surfaces, because front in now each sub-walking mechanism and two, rear brushless electric machine driving wheel all move at the upper surface of barrier, the range measurement then now laying respectively at distance measuring sensor 5 on bar 2 two ends, poor position in this each sub-walking mechanism is mutually the same, mutually the difference in height between the range measurement being attached thereto two distance measuring sensors 5 that single-chip microcomputer institute obtains in each sub-walking mechanism should be 0, then now, single-chip microcomputer in this each sub-walking mechanism controls the brushless rotary motor work be attached thereto immediately, to make in this each sub-walking mechanism difference position bar 2 under the control of corresponding brushless rotary motor, return to initial angle, namely the difference in height on these bar 2 two ends, difference position between distance measuring sensor 5 range measurement is made to return back to elemental height difference, the surface that all the other each the sub-walking mechanisms being arranged at sweeping robot 1 lower surface equally all move to barrier by above-mentioned moving process is moved, continue to move until whole sweeping robot clears the jumps, substantially increase the property passed through of sweeping robot, wider cleaning can be realized, effectively ensure that the cleaning works efficiency of sweeping robot.
Be explained in detail for embodiments of the present invention in conjunction with Figure of description above, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept.
