The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
See also Fig. 1, shown in Figure 2, front portion, the lower end of seat 1 and preceding elevating lever 12 are hinged among the figure, and rear portion and rear support stand 2 are hinged.The lower end of preceding elevating lever 12 is hinged on the vehicle frame 6.Also be fixed with pedal 11, front walking wheel 9 on the preceding elevating lever 12.Be packed in back elevating lever 28 is housed in the rear support stand 2 on the vehicle frame 6, as Fig. 4, shown in Figure 5, gear is equipped with in the upper end of back elevating lever 28, and the gear 32 in this gear and the motor 31 forms drive connection.Lower end screw thread at back elevating lever 28 is connected with lifter plate 30, and the lower end of lifter plate 30 is provided with outrigger shaft, on the axle sprocket wheel 7 and rear walking wheel 15 is housed.Main motor 5, storage battery 8, support 4, preceding support wheel 10, back support wheel 3 also are housed on vehicle frame 6.Wherein, main motor 5, support 4, back support wheel 3 all are positioned at the rear portion of vehicle frame 6.Storage battery 8 is used to supply with the car load electricity consumption.Photoelectric sensor 17 before being equipped with on the pro-support wheel 10 is equipped with back photoelectric sensor 18 on the back support wheel 3.
Figure 3 shows that the internal structure sketch map of main motor 5.Balladeur train 26 is housed on the main shaft 25 among the figure, and an end of balladeur train 26 is provided with gear 27, is used for forming drive connection with gear 23.Periphery at balladeur train 26 is a hinge wheel 16, and hinge wheel 16 is synchronized with the movement with gear 23.The periphery of balladeur train 26 also is provided with stirs groove, and clutch 24 moves balladeur train 26 by stirring this groove on main shaft 25.The overhanging end of main shaft 25 is equipped with sprocket for main drive 19, and the overhanging end of an end of sprocket for main drive 19 and balladeur train 26 is equipped with the tongue and groove that cooperatively interacts.Main motor 5 adopts 2 of dc speed-regulating motors, and motor and clutch, change speed gear box are total to as a whole.
On support 4, also be provided with sprocket wheel 29, and be wound with chain on this sprocket wheel 29 and sprocket wheel 7, the sprocket for main drive 19, form a relation of being synchronized with the movement jointly.On hinge wheel 16, preceding support wheel 10 and back support wheel 3, be wound with cog belt 14, also form a being synchronized with the movement relation, and the axis of the axis of hinge wheel 16, preceding support wheel 10 and afterwards the axis of support wheel 3 all not on same horizontal plane.
Fig. 7, Figure 8 shows that the structural representation of cog belt 14.The one side of cog belt 14 is a chain, and another side is fixed with plastic band, and has evenly distributed stepped tooth on the plastic band.
Fig. 6 is the structural representation of vehicle frame 6.Bottom at vehicle frame 6 is a chain slideway 22, is used for the cog belt 14 of supporting movement to the bottom.
Photoelectric sensor 20,21 is housed on the chair back of seat 1, controller 13 is housed, as shown in Figure 1 on the handrail.The operation principle of controller 13 as shown in Figure 9.Controller 13 is made up of four parts: control rocking bar, main machine governor, push rod controller and photoelectric sensing are controlled automatically.The control rocking bar is used to control this car action, and hand push button is finished forward and backward road wheel lifting action.Main machine governor is used to make the car gentle start, stops.The push rod controller is used to control the lifting of forward and backward road wheel.Photoelectric sensing control automatically is used for sending instruction when stair activity and leaping over obstacles, makes rear walking wheel finish lifting action automatically.
When stair activity and across obstacle, by forward and backward photoelectric sensor 17,18 photosignal is transferred in the controller 13, assign instruction by controller 13 again: motor 31 driven wheels 32 rotate, thereby rear support stand 2 is promoted rear walking wheel 15, preceding elevating lever 12 promotes seat 1 and front walking wheel 9 in the lump, and cog belt 14 directly contacts stair or barrier.This moment, main motor 5 interior clutches 24 moved, and made balladeur train 26 and gear 23 engagements, drove hinge wheel 16, and the action of stair activity and across obstacle is finished in 14 rotations of drive cog belt.As appearance is than large deviation in the traveling process of stair activity, then the photoelectric sensor 20,21 by the wheelchair both sides transfers signals in the controller 13, assigns instruction by controller 13 again, finishes the correction action by main motor 5.
During level walking, motor 31 driven wheels 32 rotate, and rear support stand 2 is fallen rear walking wheel 15, and preceding elevating lever 12 is fallen cog belt 14 rising built on stilts in the lump with seat 1 and front walking wheel 9.This moment, main motor 5 interior clutches 24 moved, and made balladeur train 26 and sprocket for main drive 19 engagements, drove rear walking wheel 15 rotations, finished level walking and moved.
Forward and backward road wheel 9,15 all adopts pneumatic tire, has alleviated the shaking force in the motion.
