11 connections, the other end are stuck on the fulcrum 21 being connected with the pawl 20.
When in use, after foot is put in device, by way of wheel 17 of shaking the hand, handwheel 17 rotates band to user of the present invention
Dynamic main shaft 24 rotates, and main shaft 24 drives wheel rim 26 to rotate, and the rotation of wheel rim 26 twines lower leg bandage, that is, rubber strip 25 is a-circle-by-a-circle
Be wound on wheel rim 26, pawl 20 allow ratchet 18 can only toward the movement of direction, i.e., main shaft 24 can only one direction rotation, work as equipment
After wearer thinks that tightness is suitble to, handwheel 17 is unclamped, ratchet 18 is blocked by pawl 20, and main shaft 24 is not able to rotate, rubber strip
25 are constantly in the state, achieve the purpose that device is tightened with shank, and ratchet mechanism does not generate unfavorable shadow to it during tightening
It rings.When unloading device, the tension spring 19 being stuck on axis is discharged, since tension spring 19 will shrink the bullet for restoring deformation and generating
Property power, 19 contraction process of tension spring break pawl 20 into two with one's hands, and for ratchet 18 without the constraint of pawl 20, ratchet 18 will be no longer to main shaft
24 movements have an impact, i.e., main shaft 24 no longer by can only the constraint that rotates of one direction, rubber strip 25 will restore deformation and generate
Elastic force drives main shaft 24 to rotate, and in rotation process, rubber strip 25 is a-circle-by-a-circle to be laid out from wheel rim 26, reaches the mesh unloaded
's.This mechanism, which realizes, does not need to allow user's bending, tightens device as tying the shoelace, but utilizes main shaft 24 will
The part for needing artificially to participate in is put into eminence, can be under standing state when such user needs to tighten equipment with itself
It realizes to dress equipment and complete.After lower leg bandage, that is, rubber strip 25 is fixed, upper leg bandage 29 need to be unlocked first to be bundled at thigh again,
The structure of upper leg bandage 29 is similar to the safety belt structure of school bag, can adjust the length of bandage according to their needs, magic chair is worn
It wears and finishes.
During trip when rest, user only need it is micro- be sitting on leg plate 1, give upper leg plate 1 one downward power, lead to
The primary transmission bar 2 for crossing rotary axle box and the connection of upper leg plate 1, since its lower end is located in the first slideway 3, and can be along its cunning
Dynamic, when user sits down, the lower end of primary transmission bar 2 is slided along the first slideway 3 to one end of the first stepper motor 7, directly
It is self-locking by slideway to 2 forward slip of primary transmission bar to greatest limit position.Returning face plate 6 also can be with its level-one driver at this time
The movement of structure is rotated down around the turning joint connecting with returning face plate, is fixed in the second slideway 8 of 6 lower section of returning face plate at this time
12 upper end of secondary transmission bar can slide into slideway highest distance position along the second slideway 8 to a Slideslip and complete self-locking, second level passes
12 lower end of lever is then along 13 slide downward of third slideway up to the upper-end contact with the support rod 15 for being connected to gas spring.The two
While contact, gas spring 14 will will receive biggish pressure, and gas spring can be compressed, so that gas spring and support rod 15
Junction along 13 slide downward of third slideway, the sliding can cause again support rod 15 around junction revolute pair carry out
Rotation, allows the angle between support rod 15 and lower leg plate 11 to increase, so that support plate 16 also can be in the company with lower leg plate 11
The place of connecing is rotated, and allows the angle between support plate 16 and lower leg plate 11 to increase, the angle between support rod 15 and support plate 16
Reduce, to realize rotating down for support plate 16, allow support plate 16 one end and ground face contact, make generally in stablizing shape
State.Chair is rested for user at this point, this ectoskeleton chair becomes one.
When user stands, the first stepper motor 7 work being initially mounted on returning face plate 6 drives and is fixed on the
The first sliding block on one screw rod 5 pushes 2 lower end of primary transmission bar and slides to the other end of the first slideway 3, until primary transmission bar
2 lower ends touch 3 other end of the first slideway.Being sitting in the user of leg plate 1 at this time, the transmission with primary transmission bar 2 is jacked up
Certain altitude.At the same time, second stepper motor 10 is started to work, and drives in scissor structure 4 two sides connecting rod to the second screw rod
9 centers are mobile, and scissor structure, which is limited in 8 Partial angle of the second slideway and becomes smaller, at this time extends, to drive secondary transmission
Bar 12 is to another Slideslip of the second slideway 8, since the lower end of secondary transmission bar 12 and support rod 15 are compressed gas spring jointly and will be propped up
Fagging 16 support it is relatively fixed on the ground, so secondary transmission bar 12, which jacks up returning face plate 6, arrives certain angle, the also band of returning face plate 6
Its top component is moved to move upwards, and with the support rod 15 of the lower end in contact of secondary transmission bar 12 since the power for being pressed in thereon disappears
It loses, due to the effect of gas spring itself, it will be restored to former length.Will make simultaneously the junction of gas spring and support rod 15 along
Slideway 11 moves up, so that revolute pair of the support rod 15 around junction is rotated, between support rod 15 and lower leg plate 11
Angle will reduce, due to the rotation of support rod 15 will will drive revolute pair of the support plate 16 between lower leg plate 11 into
Row rotation, allows support plate 16 to be rotated up, so that the angle between support rod 15 and support plate 16 increases, support plate 16 is under
Angle between leg plate 11 reduces.Support plate 16 will be disengaged with ground at this time, with convenient for users to normal walking.In
User completes after standing, and drives the reversion of screw rod by stepper motor to restore sliding block and scissor structure to initial bit
It sets, does not influence sitting process next time.
Two single leg mechanisms can be merged into an entirety by clutch bindiny mechanism when not dressing by old man,
30 sets of connection screw thread pivoted housing can be rotated in snap ring shaft member 31 and can slide along to farthest restriction site, snap ring shaft member
31 and thread spindle component 34 be separately fixed on the upper leg plate trailing flank of the single leg mechanism of left and right leg two, by two single leg mechanism clutches
Device is close, and connection screw thread pivoted housing 30 is moved to highest distance position i.e. right end along snap ring shaft member 31, logical with thread spindle component 34
It crosses and is threadedly engaged fixation, whole device is folded into cart by self-locking by drive rod, and lower leg plate bottom roller 32, which can limit, to be turned
It is 90 ° dynamic, when becoming cart roller shaft is gone to vertical with plate face and can rolled, old man pushes handle that can then push entire machine
The movement of structure.
Light source sensor can detecte environment light, and controller feedback signal is given when environment light is partially dark, make its opening
LED illumination lamp is old man's illumination, and warning passerby and vehicle can be played by opening LED warning lamp, guarantees the safety of old man's trip.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, those of ordinary skill in the art are to this hair
Other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention,
It should all cover within the scope of the claims of the present invention.
