[specific embodiment]
Embodiment:
A kind of multifunctional wheelchair; Comprise base 1, two front-wheels 2, two trailing wheels 3, motor 4, battery 5, wheelchair backboard 6, seats plate 7, wheelchair calf plate 8, wheelchair pedal 9, four base electric pushrods 10, wheel seat support electric pushrod 11, two wheel chair back electric pushrods 12, curved rod 13, cross bar-I, II 18,20, straight-bar 19, two curved bars 21, left handrail 14, right handrail 15 and control sections; Two front-wheels 2 are driving wheel and fixing through driving shaft axle bed and base 1; Two trailing wheels 3 are universal wheel and fixing with base 1; Motor 4 all is fixed on the base 1 with battery 5; 4 in motor is connected with front-wheel 2 driving shafts; Respectively hinged and when horizontal development, form the rectangle bed board between wheelchair backboard 6, seats plate 7, wheelchair calf plate 8 and the wheelchair pedal 9, an end of four base electric pushrods 10 is hinged with base 1 spherical pair respectively, and the other end is hinged through spherical pair with seats plate 7 respectively; Two wheel chair back electric pushrods 12 are connected with seats plate 7 with wheelchair backboard 6 through hinge respectively; The centre position of curved rod 13 is hinged with the centre position of a cross bar-I 18 who is fixed on wheelchair calf plate bottom, and it is hinged that an end of curved rod 13 and an end are hinged on the straight-bar 19 in centre position of a cross bar-II 20 of wheelchair calf plate 8 bottoms, and an end and seats plate 7 bottom surfaces of taking turns seat support electric pushrod 11 are hinged; The other end and curved rod 13 are hinged; The centre position of two curved bars 21 and wheelchair calf plate extension are hinged, and curved bar one end is fixedly connected with cross bar-II, and the other end is equipped with roller; Be slidingly connected through groove with wheelchair pedal 9, wheelchair calf plate 8 and wheelchair pedal 9 are through 13 interlocks of camber connecting rod; Left side handrail 14 is arranged at the both sides of wheelchair backboard 6 respectively with right handrail 15 and can rotates the back up and down and fix; Control section comprises that stick 16 and control button 17 also are arranged at respectively on the handrail of the left and right sides; Wherein stick 16 is arranged at and is used to control advancing, retreat, turn left, turning right of wheelchair on the right handrail 15; Control button 17 is arranged at and is used to control wheelchair sitting posture and stance and the conversion that lies low on the left handrail 14, and control section is connected with battery 5 through lead respectively with each electric pushrod.
The actual operating position of this multifunctional wheelchair:
1) wheelchair is transformed into the realization of the action that lies low by sitting posture
Press the control button 17 that lies low on the left handrail 14, wheelchair begins from sitting posture to the attitude conversion that lies low.Two electric pushrods 12 of wheelchair backboard 6 begin to shorten, make the wheelchair backboard around with the rotation of seats plate 7 hinged places, the wheelchair backboard levels off to level gradually.In this simultaneously, the wheelchair electric pushrod 11 of seats plate 7 bottoms begins elongation, through the interlock of curved rod 13 and straight-bar 19, promotes wheelchair pedal 9 and wheelchair calf plate 8 around rotating with seats plate 7 articulated position, levels off to level gradually.Finally realize from the conversion of sitting posture to bed flat position.From the conversion that lies low to sitting posture is the reversing of motion with each electric pushrod.
2) from the realization of sitting posture to bent lower limb action
The limiting mechanism of wheel on the seat base 1 pins two electric pushrods in back 10, makes the elongation push rod that it can only be straight up.Limiting mechanism is with the restriction cancellation of two electric pushrods 10 in front.Said limiting mechanism is an electromagnetic valve, gets four electric pushrods on the base, and each electric pushrod next door correspondence is equipped with an electromagnetic valve.Electromagnetic valve has a pin, and under the closing state, pin inserts among the spherical pair connection, has limited electric pushrod and has rotatablely moved.Electromagnetic valve energising pin is inhaled back, the restriction cancellation.The direction of two electromagnetic valve pins on the same direction is orthogonal.The push rod of two electric pushrods 10 in front elongation simultaneously makes seats plate 7 rotate around the pin joint with wheelchair backboard 6, and seats plate 7 is by jack-up.Electric pushrod 11 push rods of seats plate 7 bottoms extend one section simultaneously, make wheelchair calf plate 8 around rotating up with seats plate 7 pin joints.Realize the purpose of bent lower limb.
3) wheelchair is by the realization of sitting posture to the stance translation function
Press the switching button of standing of left side handrail 14.The restriction cancellation of wheel seat base latter two electric pushrod 10, two electric pushrod 10 push rods elongations in back simultaneously promote seats plates 7 around with the rotation of wheelchair calf plate 8 hinge point, make seats plate 7 level off to erectility.In this simultaneously, the wheel seat support electric pushrod 11 under two electric pushrods in wheelchair backboard 6 rear portions 12 and the seats plate extends simultaneously, and coordination wheelchair backboard 6 is accomplished wheelchair with the motion of wheelchair calf plate 8 and seats plate 7 and uprightly moved.After action was accomplished, wheelchair was transformed into the attitude of standing, and electric pushrod outage simultaneously utilizes auto-lock function, fixedly the attitude of standing of wheelchair.Stick 16 through controlling on the right handrail 15 is all around walked.Patient or old people can be free movable under upright posture.By standing attitude when sitting posture is changed, the action of all electric pushrods is opposite, is shunk by elongation state, and the conversion of slave station standing position attitude to sitting posture accomplished in each electric pushrod coordination exercise.
