Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail:
Such as Fig. 1, the present invention is a kind of lower limb recovery wheelchair for being able to achieve adjustable elliptical orbit, including wheelchair part and ellipse Two parts of path implementation device, including vehicle frame 10, the seat 30 and handrail 40 being fixed on vehicle frame 10, big wheel 50 lead to It crosses axis transmission to be fixed on vehicle frame 10, support wheel 90 and directive wheel 80 are bolted on vehicle frame 10.Elliptical orbit is realized Device 20 is bolted on vehicle frame 10.Motor 60, which is bolted, to be fixed on vehicle frame 10.
Such as Fig. 1 and Fig. 4, adjustable elliptical orbit lower limb recovery wheelchair of the invention, patient is sitting on wheelchair, both feet is placed in ellipse On the pedal of Circular test realization device, drives patient's both feet to carry out the movement of elliptical orbit by elliptical orbit realization device, reach The purpose of rehabilitation.The elliptical orbit realization device is offset slider-crank mechanism.The output shaft of the motor 60 passes through belt 70 impart power to the driven wheel 201 of elliptical orbit realization device.The driven wheel 201 is connected to solid by central axis 202 In reservation 211, two sides crank 203 is connected in fixing seat 211 by central axis 202, and two sides crank is in angle 180 degree cloth It sets, can be rotated simultaneously with driven wheel 201.The two sides crank 203 has the sliding slot of an inverted trapezoidal, position limiting slide block 204 1 above Side is bonded with sliding slot, can in sliding slot along the chute direction slide, position limiting slide block by bolt 205 squeeze fastening limited. 204 other side of position limiting slide block is connect with connecting rod rack 207 by crank rotation axis 206.Two sides connecting rod rack 207 is L-shaped, connecting rod Bracket 207 is connect by crank rotation axis 206 with position limiting slide block 204 with one end, and the other end is connected by bolt and road wheel 213 It connects.Pedal 210 is connected by shaft with sliding block 208, and sliding block 208 is c-shape, can be bonded with connecting rod rack 207 and above Sliding, is fixed by collision bead position limiting structure 212 and limit hole 209.Collision bead position limiting structure schematic diagram such as Fig. 6 and Fig. 7.? Just like position limiting structure 212 shown in Fig. 7 on sliding block 208, there is a trapezoidal hole on sliding block 208, wherein it is placed with spring 2121, Collision bead 2122 and closure lid 2123.2121 side of spring is contacted with collision bead 2122, and the other side is contacted with closure lid 2123, is closed Lid 2123 is threadedly coupled with position-limiting hole.Under the active force of spring 2121, collision bead 2122 can only under the limitation of trapezoidal hole Expose certain size, 2122 exposed portion of collision bead falls into the limit hole 209 on connecting rod rack 207, plays position-limiting action, make to slide Block cannot slide.When compared with sliding block 208 is pushed under noticeable effort, collision bead can be retracted under extrusion in trapezoidal hole, make sliding block 208 It is slided along connecting rod 207, until encountering next limit hole.By the position for changing sliding block 208 and position limiting slide block 204, so that it may Adjust elliptical orbit, the actual conditions of Lai Shiying patient.The elliptical orbit realization device 20 by bolt by fixing seat 211 with Vehicle frame 10 connects.
Vehicle frame 10 of the present invention is welded using aluminum pipe bending, seat 30, and handrail 40 uses injection molding.It is ellipse Circular test realization device is cut using aluminium panels, is welded.Finally various pieces component is being assemblied together.
The application method of this product:
When elliptical orbit lower limb recovery wheelchair adjustable using the installation present invention, it is first depending on the suggestion of physiatrician, it will Sliding block 208 and position limiting slide block 204 on elliptical orbit realization device 20 are adjusted to suitable position, transport elliptical orbit realization device Elliptical orbit after going is suitble to the normal gait of patient.It allows patient to be sitting on the seat 30 of wheelchair, the both feet of patient is consolidated It is scheduled on pedal 210.It turns on the power switch, motor 60 drives the movement of elliptical orbit realization device, and then patient is driven to carry out health Movement is practiced in refreshment.
Fig. 4 shows the motion process of elliptical orbit realization device 20 in the present invention, and motor 60 is driven ellipse by belt 70 Driven wheel 201 on Circular test realization device 20 rotates, and then drives crank 203, and connecting rod rack 207 moves, finally by foot It pedals 210 drive patient feets and realizes elliptical orbit movement.It can basis by adjusting the position of sliding block 208 and position limiting slide block 204 Patient demand adjusts elliptical orbit in a certain range, it is made to be more in line with patient requests.
To sum up, elliptical orbit realization device and wheelchair are incorporated in one by the adjustable elliptical orbit lower limb recovery wheelchair of the present invention It rises, while the adjustment of elliptical orbit can be carried out according to the actual conditions of patient, furthermore the present invention changes previous lower limb rehabilitation and produces Product can only carry out the limitation of rehabilitation training in fixed place, can be convenient and be moved to different places, meet the personalized need of patient It asks.
Although above in conjunction with figure, invention has been described, and the invention is not limited to above-mentioned specific embodiment parties Formula, the above mentioned embodiment is only schematical, rather than restrictive, and those skilled in the art are inventing Enlightenment under, without deviating from the spirit of the invention, many variations can also be made, these belong to protection of the invention Within.
