In figure, 1. support bar, 2. leg support frame, 3. connecting rod, 4. connecting rod I, 5. connecting rod II, 6. bearing, 7. spring, 8. bevel pinion, 9. crank connecting link, 10 lateral shafts, 11. bevel gear wheels, 12. axle I, 13 motors, 14. axle II, 15. baffle plates.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, the bionical slewing equipment of leg recovery, comprise leg support frame 2, and leg support frame 2 is connected with power source by crank and rocker mechanism, side steering.
Power source is motor 13, and side steering comprises that the bevel pinion 8 be arranged on motor 13 output shafts reaches and the bevel gear wheel 11 of its engagement, and bevel gear wheel 11 is connected with crank and rocker mechanism.
Crank and rocker mechanism comprises lateral shaft 10, and bevel gear wheel 11 is arranged on lateral shaft 10, and lateral shaft 10 is connected with leg support frame 2 by transmission component.
The two ends of lateral shaft 10 are connected with respectively one group of transmission component, and two groups of transmission components are connected with a leg support frame 2 respectively.
Two groups of transmission components are arranged on same bearing 6.
Transmission component comprises connecting rod I 4, connecting rod II 5 and connecting rod 3 and all is arranged on axle I 12, and connecting rod 3 is connected with leg support frame 2, and connecting rod I 4 is connected with crank connecting link 9 by axle II 14, and connecting rod II 5 is connected with bearing 6.
Leg support frame 2 is connected with connecting rod 3 by support bar 1, leg support frame 2 with support bar 1 for being threaded.
The place ahead of leg support frame 2 is provided with spring 7, and spring 7 is arranged on block 15.
Core institution of the present utility model is crank and rocker mechanism, and this mechanism is comprised of crank connecting link 9, connecting rod I 4, connecting rod II 5; The left and right sides all adopts this structure.In this mechanism, all degree of freedom are 1, only to do gyration or swing.Bevel pinion 8, bevel gear wheel 11 and lateral shaft 10 form side steering, make vertical rotation of motor 13 convert lateral rotation to, with the motion of driving crank endplay device.Like this, will convert swing mechanism to through motor-driven circumgyration campaign, to realize the movement locus of support bar 2.The another one structure is foot's load carrying, and the left and right sides is respectively equipped with spring 7 and block 15; When shank is done oscillating motion, foot also moves back and forth thereupon, to foot, increases load, is conducive to the recovery in each joint of shank.
Crank and rocker mechanism of the present utility model has the advantages that there is no quick return, and oscillating motion is steady; Connecting rod I 4 adopts passive constraint, increases carrying, makes structure more stable; The use of bevel gear makes transmission more steady, more efficient, and saves work space.
Leg support frame 2 of the present utility model and support bar 1 have the screw thread self-locking function, can regulate arbitrarily the height of support bar 1, facilitate all kinds of crowds to use.
Referring to Fig. 2, when lower limb is placed on leg support frame 2, motor 13 rotates, to vertically rotate and be converted into lateral rotation by large bevel pinion, then lateral shaft 10 adopts key to be connected with toggle, the phase contrast of two pairs of toggles that connect due to lateral shaft 10 both sides is 180 °, just simulates leg reciprocating motion.
When leg reciprocating motion, foot is also being done linear reciprocating motion.There are spring 7 and block 15 in foot, forms the foot motion structure.Pedal is on spring 7, and spring 7 is simulated the shank integral body, and particularly joint bears load, and each joint of shank and muscle are better recovered.Spring 7 apart from foot apart from capable of regulating, the elastic force of spring 7 is scalable also, to meet each build, each body constitution people's demand.
Referring to Fig. 2, two positions the most extreme during for leg exercise.Phase angle, two positions is 73.51 °, there is no quick return.The reciprocating motion speed of lower limb is identical, has guaranteed the comfortable of sufferer.The swing of wide-angle can improve the leg movements scope, moves more reasonable, also more puts in place.
Two positions all become 20 ° of angles with horizontal plane, be because will meet the leg exercise rule: lower limb is raised at peak, and putting down is horizontal level substantially.
Leg support frame 2 adopts and is threaded with support bar 1, forms self-locking structure: screw thread can make leg support frame 2 adjust arbitrarily height; Self-locking can allow it keep arbitrary height and do not glide under the effect of shank pressure.
This utility model is a kind of auxiliary treatment apparatus.When the people lies down, the bending of shank is stretched can regard slider-crank mechanism as, if just only see the movement locus of thigh, can simplify and become crank and rocker mechanism.In order to reduce the complexity of rehabilitation device design, and be convenient to routine use and maintenance, select crank and rocker mechanism to carry out the proper motion of simulating human shank, thereby help the patient to realize the rehabilitation of shank.Crank and rocker mechanism, be mainly used in gyration be converted to the occasion that swings or swing is become to rotation.The structure condition of crank and rocker mechanism is: 1. the length of each bar should meet the bar elongate member; 2. its quarter butt is side link or frame; 3. its king-rod elongate member: quarter butt is long+stock length<=all the other two pole length sums.In crank and rocker mechanism, also have some basic fundamental key elements to consider, such as its quick return, drive line angle, dead point etc.In leg recovery, because be that patient uses, thus must quick return can not be arranged, otherwise may cause secondary injury.Simultaneously, increase as far as possible drive line angle, avoid dead angle.
This utility model adopts linkage, have bearing capacity large, wear and tear little, processing is simple and the easy advantage such as adjusting.The passive constraint that sliding pair between passive constraint connector and support is this swinging joint, can strengthen the intensity of structure.
