Detailed description of the invention
Be described in detail below in conjunction with drawings and Examples.
With reference to Fig. 1, a kind of Wearable five finger gymnastic mechanical hand, comprises robot base 1, and robot base 1 upper side plane is used for fixing hand frame for movement and power control system, downside be arcwall face to adapt to staff back structures, be fixed on hands portion by binder, hand frame for movement is that five groups of identical structures are applicable to the five fingers, its structure is: robot base fixes line handspike motor 3 by motor firm banking 2 on 1, the flexing that line handspike motor is mechanical hand and stretching, extension provide power, line handspike motor 3 and motor firm banking 2 are linked by pin and can rotate around the pin on motor firm banking 2, line handspike motor 3 end connects one end of arc frame 5 by pin and can relatively rotate, the other end of arc frame 5 is connected with push rod 6 one end, arc frame 5 is provided with telescopic hole, for just regulating arc radius to adapt to the size of different staff, hole on arc frame 5 is coaxially connected with the hole of double-side-position fixed mount 4, push rod 6 other end is connected with finger holder 9, finger holder 9 is provided with binder, be fixed by binder Fingers, finger holder 9 and binder are also provided with the pressure transducer 10 detecting finger extension and the pressure transducer 11 detecting FF, for detecting the size of patient's finger motion intention and corresponding force,
Described push rod 6 is provided with bidirectionally limited hole 7, and bidirectionally limited hole 7 prevents from occurring mechanism blockage in motor process.
Described push rod 6 is arranged the adjustment hole 8 of diverse location, for regulating the height of finger holder 9, the hands for different size is trained.
Described arc frame 5 is provided with the telescopic hole of adjustable length, for regulating arc frame front end arc radius, to adapt to different people hand sizes size.
With reference to Fig. 2, what power control system comprised that the main controller 12, the main controller 12 that are connected with line handspike motor 3 adopt is based on the STM32F107VC under ARM-Cortex-M3 framework, STM32F107 has USB(OTG at full speed) interface, two-way CAN2.0B interface, and Ethernet 10/100MAC module, therefore adopt this chip can come into family/community's structure Long-distance Control for later manipulators in rehabilitation and provide hardware foundation.Signal condition unit in main controller 12 is for the treatment of the feedback signal of finger end pressure sensor 10, pressure transducer 11 and the embedded displacement transducer of line handspike motor 3, corresponding amplification filtering is carried out to sensor signal, delivers to collection plate and carry out data acquisition.The displacement signal that the embedded linear displacement transducer of line handspike motor 3 feeds back is analogue signal, can be used in the position of perception linear electric motors push rod, carries out calculating the bending angle of current finger.Sensor 11 for detecting the sensor 10 and FF stretched outside finger adopts diaphragm pressure sensor, this sensor is pressure resistance type, mechanical hand comprises and refers to inner sensors and refer to outer sensors, refer to that inner sensors is fixed on binder and the place of finger interior side contacts, refer to that outer sensors is then fixed on the place pointed dorsal part and contact with finger holder.Five fingers have two pressure transducers respectively, and therefore this mechanical hand needs ten diaphragm pressure sensors altogether.Pointing inner surface pressure when finger inner sensors 11 detects FF, pointing the motion intention of active flexion for detecting patient.Pointing outer surface pressure when finger outer sensors 10 detects finger extension, pointing for detecting patient the motion intention initiatively stretched.
Under passive rehabilitation training pattern, main controller 12, according to linear displacement transducer signal embedded in the range of movement preset and line handspike motor 3, drives hand to move.Under initiative rehabilitation training mode, main controller 12 realizes the data acquisition of finger end pressure transducer 10 and pressure transducer 11, and judge the motion intention of finger according to the signal gathered, and then line handspike motor 3 is driven to make and stretching out accordingly or retract action.
Operation principle of the present invention:
As shown in Figure 3, its working method is divided into two kinds of patterns to the control model of five finger gymnastic mechanical hands: Passive Mode and active help/resistance mode.Two kinds of model process figure respectively as shown in Figure 4,5.
Under Passive Mode is applicable to apoplexy initial stage patient's myasthenia state, finger is driven to carry out the training of flexing stretching, extension by mechanical hand.Patient wears mechanical hand, by judging that the built-in linear displacement transducer of linear electric motors judges whether hands reaches the angle on target of setting, thus determines whether motion commutation.In patient hand's motor process, if there is spasm, then spasm is alleviated in motor adverse movement.But also can by the intervalometer timing of controller inside, the monitoring training time.
Initiatively help/resistance is applicable to the patient of stroke in convalescent stage, and patient has certain muscular strength.When patient carries out pointing autonomous curvature movement, judge whether to reach setting power by detecting finger end inside pressure sensor output signal, if reach, motor inner push-rod stretches out certain distance, needs of patients continues flexing just can ensure that finger side thrust sensor output signal reaches set threshold value, so just can complete the action of FF; When patient carry out finger confess one's crime stretch training time, exporting by detecting finger end outside pressure sensor, carrying out above-mentioned similar control to complete autonomous stretching.
Because designed the five fingers manipulators in rehabilitation contains five cover finger rehabilitation exercise structures, and be respectively furnished with a line handspike motor as power, therefore the control mode under above-mentioned passive or aggressive mode is respectively used to each motor, namely difference finger adopts different range of movement or speed, can realize grasping, two and refer to the action of pinching or three fingers capture.
The operation principle of mechanical part: is terminal drawing-type structure due to the present invention's employing, therefore its course of normal operation needs could realize after staff is worn.Complete after wearing, fixed mount 4 is positioned at the back of the hand and surveys metacarpophalangeal joint, and finger holder 9 is placed near far-end articulations digitorum manus.All be hinged between motor 3 and motor firm banking 2 and arc frame 5, when motor 3 stretches out, motor 3 can promote arc frame 5 and rotate around fixed mount 4, and the transmission effect rotating through pull bar 6 and finger holder 9 of arc frame is converted into the rotation of finger end around metacarpophalangeal joints.Due to the change along with the radius of gyration in rotation process of finger joint, therefore point the rotary motion trace of holding around metacarpophalangeal joints and irregular circular arc.Owing to being all connected through the hinge between push rod 6 and arc frame 5 and holder 9, push rod 6 and arc frame 5 and point between holder 9 and can mutually rotate, therefore in FF process, push rod 6 can angle automatically between adjustment and arc frame 5 and holder 9, thus realizes self-regulating rotary and move radius.When motor bounces back, said process oppositely.
