Embodiment 2
Incorporated by reference to reference Fig. 5-6,
The structure of the electrodynamic balance car of second embodiment of the invention is substantially identical with the configuration and principle of the electrodynamic balance car of first embodiment of the invention respectively, and its difference is, position induction device comprises four displacement pickups 102 and four elastic elements 104.The two ends of described four elastic elements 104 are connected and rectangular arrangement with described stretcher 11 and described support frame 13 respectively, the deformation quantity of described four displacement pickups 102 with described four elastic element 104 one_to_one corresponding and for responding to four elastic elements 104, described four displacement pickups 102 form a four-quadrant displacement induction system with described four elastic elements 104, and for responding to the center-of-gravity position information of the user on stretcher 11.
Be understandable that, when on user stands stretcher 11, elastic element 104 is compressed by user, when the centre-of gravity shift of user, the deformation quantity of each elastic element 104 must change, such displacement pickup 102 just can collect the displacement variable of corresponding elastic element 104, control mechanism judges the centre-of-gravity displacement information of user by the deformation quantity that displacement pickup 102 collects corresponding elastic element 104, thus controls described multiple wheel 2 and move (referring to following).
Described stretcher 11 is provided with four foot-operated regions 111, four extensible vertical directions in foot-operated region 111 move up and down, in other words, namely four foot-operated regions 111 are Split type structure with the body of stretcher 11, the body of stretcher 11 such as, can be provided with four openings, pedal is separately installed with in four openings, to form foot-operated region, be understandable that, pedal is convex shape, the top of opening is such as provided with spacing flange, departs from from opening to avoid pedal.More specifically, four elastic elements 104 are positioned at installation cavity 130 and the diapire in connection chamber 130 and the bottom in four foot-operated regions 111 respectively, four displacement pickups 102 be arranged on behave affectedly 130 diapire on and with four elastic element 104 one_to_one corresponding.
The concrete principle that four-quadrant displacement induction system in electrodynamic balance car of the present invention gathers displacement information is: the left foot front portion that four elastic elements 4 are corresponding respectively, left foot heel, right crus of diaphragm front portion and right crus of diaphragm heel, when user stand on stretcher 11, if center of gravity does not offset, left foot is anterior, left foot heel, right crus of diaphragm is anterior is identical with the power suffered by the position that right crus of diaphragm heel is trampled substantially, namely now balance truck is in state of equilibrium, when the centre-of gravity shift of user, left foot is anterior, left foot heel, the anterior power be subject to right crus of diaphragm heel of right crus of diaphragm can change, now anterior with left foot, left foot heel, the deformation quantity of the elastic element 4 that right crus of diaphragm is anterior and right crus of diaphragm heel is corresponding is by difference, four displacement pickups 3 can collect the deformation quantity information of corresponding elastic element 4, namely the center-of-gravity position information of user is obtained, the center-of-gravity position information (deformation quantities of four elastic elements 4) of user that now control mechanism obtains according to four displacement pickups 3 can judge the center-of-gravity position of user.
Particularly, four displacement pickups are respectively left upper quadrant displacement pickup, right upper quadrant displacement pickup, left lower quadrant displacement pickup and right lower quadrant displacement pickup.The left upper quadrant displacement pickup received when control mechanism is identical with the displacement that right upper quadrant displacement pickup collects, the displacement that left lower quadrant displacement pickup and right lower quadrant displacement sensing collect is identical, but the displacement that left upper quadrant displacement pickup and right upper quadrant displacement pickup collect is greater than the displacement that left lower quadrant displacement pickup and right lower quadrant displacement pickup collect, now control mechanism judges that the person's of standing center of gravity tilts to dead ahead, control mechanism controls multiple wheel 2 and travels forward, contrary then control mechanism judges that the person's of standing center of gravity tilts to dead aft, control mechanism controls multiple wheel 2 and moves backward.
The left upper quadrant displacement pickup received when control mechanism is identical with the displacement that left lower quadrant displacement pickup collects, the displacement that right upper quadrant displacement pickup and right lower quadrant displacement pickup collect is identical, but the displacement that left upper quadrant displacement pickup and left lower quadrant displacement pickup collect is greater than the displacement that right upper quadrant displacement pickup and right lower quadrant displacement pickup collect, when now control mechanism judges that the person's of standing center of gravity tilts to front-left, then front-right tilts on the contrary.Certainly, in that case, if control mechanism can control (this kind of situation is that multiple wheel 2 is cardan wheel) when multiple wheel 2 can move to front-left or right, control mechanism controls multiple wheel 2 and moves to front-left or right.
Certainly, when the shift value of any one quadrant displacement pickup that control mechanism receives is maximum, can judge that the center of gravity of this person of standing is positioned at this quadrant, control mechanism can control multiple wheel 2 and make corresponding start.Such as, the shift value receiving left upper quadrant displacement pickup when control mechanism is bigger than normal, and control mechanism can judge that the center of gravity of the person of standing is positioned at left upper quadrant, and now, control mechanism controls multiple wheel 2 and turns left.
Incorporated by reference to reference Fig. 7-8,
The structure of the electrodynamic balance car of third embodiment of the invention is substantially identical with the configuration and principle of the electrodynamic balance car of first embodiment of the invention respectively, its difference is, position induction device comprises four pressure sensors 105, described four pressure sensors 105 to be folded between described stretcher 11 and described support frame 13 and rectangular arrangement, described four pressure sensors 105 form a four-quadrant pressure sensitive system, and for responding to the center-of-gravity position information of the user on stretcher 11.The concrete principle of the four-quadrant pressure sensitive system induction pressure in electrodynamic balance car of the present invention is: the left foot front portion that four pressure sensors 3 are corresponding respectively, left foot heel, right crus of diaphragm front portion and right crus of diaphragm heel, when user stand on stretcher 11, if center of gravity does not offset, left foot is anterior, left foot heel, right crus of diaphragm is anterior is identical with the power suffered by the position that right crus of diaphragm heel is trampled substantially, namely now balance truck is in state of equilibrium, when the centre-of gravity shift of user, left foot is anterior, left foot heel, the anterior power be subject to right crus of diaphragm heel of right crus of diaphragm can change, now anterior with left foot, left foot heel, the pressure collected of the pressure sensor 3 that right crus of diaphragm is anterior and right crus of diaphragm heel is corresponding will change, namely the center-of-gravity position information of user is obtained, the center-of-gravity position information (pressure informations collected of four pressure sensors 3) of user that now control mechanism obtains according to four pressure sensors 3 can judge the center-of-gravity position of user.
Described stretcher 11 is provided with four foot-operated regions 113, four extensible vertical directions in foot-operated region 113 move up and down, in other words, namely four foot-operated regions 113 are Split type structure with the body of stretcher 11, the body of stretcher 11 such as, can be provided with four openings, pedal is separately installed with in four openings, to form foot-operated region, be understandable that, pedal is convex shape, the top of opening is such as provided with spacing flange, departs from from opening to avoid pedal.More specifically, four pressure sensors 105 are positioned at installation cavity 130 also respectively against the diapire of installation cavity 130 and the bottom in four foot-operated regions 113.
Be understandable that, four pressure sensors are respectively left upper quadrant pressure sensor, right upper quadrant pressure sensor, left lower quadrant pressure sensor and right lower quadrant pressure sensor.The left upper quadrant pressure sensor received when control mechanism is identical with the pressure that right upper quadrant pressure sensor collects, the pressure that left lower quadrant pressure sensor and right lower quadrant pressure sensor collect is identical, but the pressure that left upper quadrant pressure sensor and right upper quadrant pressure sensor collect is greater than the pressure that left lower quadrant pressure sensor and right lower quadrant pressure sensor collect, and the pressure component of working direction is greater than the pressure component of direction of retreat, now control mechanism judges that the person's of standing center of gravity tilts to dead ahead, control mechanism controls multiple wheel 2 and travels forward, contrary then control mechanism judges that the person's of standing center of gravity tilts to dead aft, control mechanism controls multiple wheel 2 and moves backward.
The left upper quadrant pressure sensor received when control mechanism is identical with the pressure that left lower quadrant pressure sensor collects, the pressure that right upper quadrant pressure sensor and right lower quadrant pressure sensor collect is identical, but the pressure that left upper quadrant pressure sensor and left lower quadrant pressure sensor collect is greater than the pressure that right upper quadrant pressure sensor and right lower quadrant pressure sensor collect, the pressure component being specially front-left is greater than the pressure component of front-right, when this Time Controller judges that the person's of standing center of gravity tilts to front-left, then front-right tilts on the contrary.Certainly, in that case, if control mechanism can control (this kind of situation is that multiple wheel 2 is cardan wheel) when multiple wheel 2 can move to front-left or right, control mechanism controls multiple wheel 2 and moves to front-left or right.
Certainly, be understandable that, when the force value of any one quadrant pressure sensor that controller receives is bigger than normal, can judge that the center of gravity of this person of standing is positioned at this quadrant, control mechanism can control multiple wheel 2 and make corresponding start.Such as, the force value receiving left upper quadrant pressure sensor when control mechanism is maximum, and control mechanism can judge that the center of gravity of the person of standing is positioned at left upper quadrant, and now, control mechanism controls multiple wheel 2 and turns left.
