Coming scrutineer's center of gravity to swing situation with balance performance monitor, is the method for a kind of faster quantitative assessment balanced capacity of development in recent years.Whether move according to ergograph, the equilibrium function test macro: static equilibrium instrument and dynamic equilibrium instrument if being divided into two kinds.The static equilibrium instrument mainly stands in the variation of barycenter trajectory on the static ergograph by the analyst, and the value of relevant assessment parameters is come the equilibrium function of test person.Its shortcoming is three sensory systems not to be made a distinction research fully.The dynamic equilibrium instrument be on the basis of static equilibrium instrument, utilize control device below the ergograph that pedal or ergograph are carried out about, sagittal swing, person under inspection's somesthetic sensibility is interfered, carries out visual interference simultaneously, realized the separately research of three system areas.The pedal of dynamic equilibrium instrument is by making its method around two orthogonal axle rotations realize that each is to swinging at present, but the control of this pedal needs to realize that by Rotating Transition of Coordinate this relates to matrix operations, the algorithm complexity, operand is big, the hardware and software cost height.And the amount of calculation of this utility model by 3 Position Control pedal obliquity and attitudes reduce greatly, and algorithm is simple, can use single-chip microcomputer directly to control, and has reduced the hardware and software cost of dynamic pedal.
Three, summary of the invention
This utility model provides a kind of dynamic pedal device that is applied to the dynamic equilibrium function test system, and this apparatus structure is simple, has realized the universal swing of pedal, is easy to control, and is with low cost.
This utility model adopts following technical scheme:
Form by ergograph and dynamic pedal, ergograph comprises the ergograph casing, in the ergograph casing, be provided with at least 3 force transducers, dynamic pedal is located on the ergograph, it is characterized in that dynamic pedal is by pedal support, pedal and screw-drive mechanism are formed, screw-drive mechanism comprises motor and guide rod, motor and guide rod are connected in pedal support, on the motor power output shaft, be connected with screw rod, be connected with L bracket at screw flight, this support be slidingly connected for the guide rod of its guiding, on this support, be provided with universal joint and be connected with an end of universal joint, the other end of universal joint is connected with above-mentioned pedal, and the contact of above-mentioned force transducer contacts when force transducer is worked with the pedal support of dynamic pedal.
This utility model is to be rotated by the driven by motor screw rod, realizes moving up and down of support, and by determining the pedal incident angle, each of realization pedal is to swing again.
Compared with prior art, the utlity model has following advantage:
(1) this utility model is determined a plane by three groups of said mechanism, and each of realization pedal satisfied the demand of balance test and medical research to swing.(2) corner of this mechanism's motor is directly proportional with the displacement of universal joint, is easy to the incident angle of control pedal.(3) compare with the method for other control pedal attitudes, the amount of calculation by 3 Position Control pedal obliquity and attitudes reduces greatly, and algorithm is simple, can use single-chip microcomputer directly to control, and has reduced the hardware and software cost of dynamic pedal.
