Compared with present technology, the beneficial effect of this utility model is embodied in:
1, this utility model simple in structure, be convenient to be integrated on other rehabilitation and fitness training apparatus, seat, massage armchair and the wheelchair.
2, this utility model applied range can be used for the rehabilitation and the exercise of upper and lower limb.
3, this utility model exercise mode is various, is symmetrically arranged in two pairs of devices by a left side/right hand and a left side/right lower limb in the use, can realize the synchronous/asynchronous training.
4, this utility model compact conformation is flexible, can free folding and unfolding, can fold when not using, and it is little to take up room.
5, the utlity model has controllability; The position of supporting, the angle of side link can realize the combination type adjusting; Realize the training of different tracks, different amplitudes; Make it can adapt to the situation of same position trainer in the exercise of different convalescences and physical training condition, the trainer that can satisfy different heights again carries out the demand of rehabilitation and exercise.
6, control driven by motor crank or side link through clutch, the drive motors of crank and side link can be same.
7, if the active power shaft and initiatively in the actuating device or outer setting resistance link such as magnetic powder brake, the brake of moment adjustable friction, spring etc. are arranged, just can carry out passive exercise; Like this, just can realize main passive exercise, not only can be used as convalescence exerciser and make and be used for the rehabilitation limbs, and can make as health and fitness facilities and be used for health invigorating through motor and resistance link.
8, support connects firmly on slide block, and slide block can move along the guide rail of moving block, and moving block can drive rotation by worm gearing, makes to support can to rotate and move with respect to connecting rod; Can rotate worm gearing and support is rotated and moved to screw pair through manual work, also can rotate worm gearing and support is rotated and moved to screw pair, the convenient position adjustments that supports through motor; And making that the track that supports is more complicated, the training amplitude of upper and lower extremities is bigger.
Description of drawings:
Fig. 1 is the main TV structure sketch map of this utility model; Fig. 2 is the left view of this utility model.
Label among the figure: 1 crank, 2 first connecting rods, 3 second connecting rods, 4 side links, 5 frames, 6 support 7 main motion power shafts, 8 main drives, 9 assisted movement power shafts, 10 auxiliary drives, 11 moving blocks, 12 slide blocks, 13 screw pairs, 14 worm gearings.
Below pass through the specific embodiment, and combine accompanying drawing that this utility model is described further.
The specific embodiment:
Embodiment: referring to Fig. 1,2, the healthy training devices of adjustable significantly upper and lower extremities of present embodiment, it comprises:
Crank 1, first connecting rod 2, second connecting rod 3, side link 4, frame 5, support 6; One end of crank 1 and frame 5 hinged formation revolute pairs; The hinged formation revolute pair of the head end of the other end and first connecting rod 2; The hinged formation revolute pair of the head end of the end of first connecting rod 2 and second connecting rod 3, the hinged formation revolute pair of the head end of the end of second connecting rod 3 and side link 4, the end of side link 4 and frame 5 hinged formation revolute pairs; Support 6 and be installed on the slide block 12 of moving block 11, slide block 12 is driven by the screw pair on the moving block 13 and moves along the guide rail on the moving block; Moving block 11 connects firmly on the worm gear of worm gearing 14, and worm gearing 14 is installed on first connecting rod 2 or the second connecting rod (3).
Crank 1 and connecting rod rest 4 are driven by actuating unit on the frame 5.Crank 1 drives rotation by the main motion power shaft of being located on the frame 57 through main drive 8; Side link 4 drives rotation by the assisted movement power shaft of being located on the frame 59 through auxiliary drive 10; Main drive 8 and auxiliary drive 10 are train; Auxiliary drive 10 is provided with brake.
In actual the use; Body parameter and training requirement according to training objects; The worm screw that rotation is installed in the worm gearing 14 on first connecting rod 2 or the second connecting rod makes the moving block 11 that connects firmly on worm gear rotate; The screw rod that rotates the screw pair 13 of moving block again makes slide block 12 move, and like this, can adjust the correct position that supports on 6 arrival first connecting rods or the second connecting rod.To correct position, brake work or auto-lock function play a role and keep side link motionless assisted movement power shaft 9 through auxiliary drive 10 adjustment side links 4.The hand of trainer's upper limb (foots of lower limb) contacts with the handle (riding) that supports, and main motion power shaft 7 drives the revolution of crank 1 complete cycle through main drive 8, and crank drives track and the speeds of support handle (riding) by expection, reaches training objectives; If the movement locus of the handle (riding) that supports is not in the suitable range of movement of user; The position adjustment that then side link is turned an angle and realizes respective range; Make the movement locus of support handle (riding) in the suitable range of movement of user, thereby also can satisfy different crowd or individual training demand.
If in main motion power shaft 7 and main drive 8 or the outside load onto drag devices such as magnetic powder brake, the brake of moment adjustable friction, spring etc.; Can control the size of the moment of resistance; For training initiatively provides resistance, be implemented in the purpose of carrying out strength building in the active exercise of regulation track; In conjunction with the passive exercise of motor, thereby can satisfy the needs of main passive exercise.
On main motion power shaft 7 and assisted movement power shaft 9, load onto clutch respectively, then can control driven by motor crank or side link through clutch, like this, the drive motors of crank and side link can be same.
If in main motion power shaft 7 and main drive 8, brake is housed, then be symmetrically arranged in two pairs of devices by a left side/right hand and a left side/right lower limb in the use, can adjust the initial phase of both sides respectively and remain unchanged, thereby the realization synchronous/asynchronous is trained.
When if crank rotates, worm screw, screw rod make to be supported on first connecting rod or the second connecting rod and rotate, move that then support and can realize complex track motion more, the training amplitude of upper and lower extremities is bigger again through motor-driven.
