The operation principle of the present invention is as follows：
Referring to Fig. 2~Fig. 3, the present invention can realize quick locomotive function under wheelchair state, and its specific implementation is：Rotation
Rotating motor I102 works, the sprocket wheel 601 and chain for being passed to power in thigh bar, shank bar and bottom bar by bevel gear set I110
On bar 602, via three-level Chain conveyer, most power is reached on hind axle 704 at last, realizes the continuous rolling of trailing wheel 104, Jin Ershi
The quick locomotive function of existing wheelchair.
Fig. 4~Fig. 6 is referred to, in human body standing process is aided in, rotary lock structure is always maintained at locking condition.Because
Sat down initial stage in human body, lock pin 302 is under electric rotating machine II driving, along rectangular slot to knee under the effect of ball-screw 303
Joint direction is moved, and extracts the fore shaft on bottom bar 105 out, now the relative shank in the presence of linear electric motors II108 of bottom bar 105
Bar 106 rotates, until trailing wheel 104 and front-wheel 107 contact to earth, afterwards lock pin 302 under electric rotating machine II driving,
Ball-screw 303 moves under acting on along rectangular slot to ankle-joint direction, and the fore shaft inserted on bottom bar 105 simultaneously remains stationary as.
During this, shank bar 106, the remains stationary of bottom bar 105, mechanism aid under the two linear electric motors II108 in left and right driving
Human body is stood, and detailed process is：
First, Horizontal control lever 401 is controlled manually, it is rotated around hip joint to horizontal fix bar 403 and is fixed on elasticity
On lock 404, buckle Y types and separated with bottom bar 105, linear electric motors II108 stretches out afterwards, now shank bar 106 and bottom bar 105
Keep locking not relatively rotate in the presence of rotary lock structure, so thigh bar 103 rotates around knee joint 702, drive
Risen with the chair seat board 113 that thigh bar 103 is connected by chute 114, while waist bar 101 is under linear electric motors I109 driving
Rotated relative to thigh bar 103 by meeting in human body standing process in a manner of Hip Angle change, auxiliary human body is stood.Auxiliary
Help in standing process, footrest mechanism is also being moved with the progressively standing of human body, i.e. linear electric motors III work, passes through Dalian
Bar 202, small rod 204 drive pedal 203 to move to contact parallel to the ground, complete the process that auxiliary human body is stood.
Fig. 6~Fig. 7 is referred to, after auxiliary human body is stood, lock pin 302 is under electric rotating machine II driving, in ball
Leading screw 303 moves under acting on along rectangular slot to knee joint direction, extracts the fore shaft on bottom bar 105 out, now bottom bar 105 is straight
Relative shank bar 106 rotates in the presence of line motor II108, until bottom bar 105 is parallel with shank bar 106, Zhi Housuo
Pin 302 moves under electric rotating machine II301 driving under the effect of ball-screw 303 along rectangular slot to ankle-joint direction,
Fore shaft on insertion bottom bar 105 simultaneously remains stationary as, and this state keeps constant in human walking procedure.
Refer to Fig. 1, Fig. 7, after completing the packing up of bottom bar 105, the work of silk transmission mechanism, electric rotating machine III502 driving cones
Gear train II503 drives cylindrical rod piece 504 to rotate, and silk 507 is rolled along pulley 506, the seat support that will be connected with silk 507
Plate 113 is retracted to along chute 114 in the headspace of backboard 112, completes mechanism from wheelchair state to the conversion of ectoskeleton state.
Refer to Fig. 8, collective effect of the human body in linear electric motors I108, linear electric motors II109 and linear electric motors III201
Under, shank bar 106 rotates around knee joint 702, and thigh bar 103 does rotary motion around hip joint 701, and pedal 203 exists
Rotated under the constraint of four-bar mechanism around ankle-joint 703, so as to realize auxiliary user's walking function.Detailed process is：
Linear electric motors I108 is flexible to drive the bottom bar 105 be hinged with it to move, because rotary lock mechanism limits bottom bar 105 and small
Rotation between leg bar 106, so the drive of bottom bar 105 is connected thereto integral shank bar 106 and rotated around knee joint 702, it is real
Now aid in the function of shank movement.At hip joint 701, linear electric motors II109 is flexible to drive thigh bar 103 relative to waist bar
101 rotate, and realize the function of auxiliary thigh movement.It can realize that knee joint 702 and hip joint 701 rotate by programming Control
Angle is changed by the angle of setting.
The present invention is not limited to embodiments described above.The description to embodiment is intended to describe and said above
Bright technical scheme, above-mentioned embodiment is only schematical, is not restricted.Do not departing from
In the case of present inventive concept and scope of the claimed protection, one of ordinary skill in the art is under the enlightenment of the present invention
The specific conversion of many forms can be also made, these are belonged within protection scope of the present invention.
