The backrest of seat is movable, and moving axis 26 swings can rotate.The hydraulic support leg of four retractables of two rows before and after below seat, installing:, hydraulic support leg 2 behind two preceding hydraulic support legs 1 and two, play a part to support and transmission gravity.Their upper hinge is below seat, and the lower end adopts four bar structure hinges on the side plate of left and right sides walking mechanism outer protective cover 16; Prolong protective cover side plate hinge outside the transverse link 3,4 of hydraulic support leg lower end, two ends, the left and right sides with both sides.Seat can be swung on longitudinal and transverse two axial lines.Be equipped with two groups of liquid storage cylinders 5 and pipe fitting between the supporting leg of front and back, two discharge opeings press the hydraulic cylinder of supporting leg to be connected before and after making.Be equipped with piston, back-moving spring or compressed air in two groups of liquid storage cylinders, and pressure regulation device; On the cylinder body of back supporting leg, be provided with umbrella shape gripper shoe 14.
Two covers about walking mechanism is divided into, every cover comprise driving wheel 6, preceding support wheel 7, back support wheel 8, compositions such as front jocket wheel 9, following wheel 10, crawler belt 11 and outer protective cover 16.The axle of driving wheel 6 is fixed on the protective cover 16, and the gravity that it and preceding support wheel 7, back support wheel 8 are carried transmits by double pendulum spare 17; Preceding support wheel 7, back support wheel 8 are assemblied in the two ends of double pendulum spare 17.Double pendulum spare 17 hinges are at turning cylinder 27 places of protective cover protective cover 16 side plates, and can rotate around it.Axle with wheel 10 is fixed on the single pendulum spare 18.One end of single pendulum spare 18 is contained on the wheel shaft of driving wheel 6 by bearing holder (housing, cover); The other end of single pendulum spare 18 has vertical slotted eye 19.Arrange after vertically slotted eye 19 is contained in by bearing holder (housing, cover) on the axle of support wheel 8 at random.When after when arranging the change in location of support wheel 8 at random, the position of single pendulum spare 18 also changes thereupon.And swing around live axle.Mounted thereto also and then shifts one's position with wheel 10.Lower edge with wheel 10 and its front and back two-wheeled is in same linear position all the time, and it is also bearing part gravity.Front jocket wheel 9 links to each other with the axle of preceding support wheel 7 by gripper shoe 20, and they are the change location with the change in location of preceding support wheel 7 also.The axis of front jocket wheel 9 is contained in the strip stopper slot 21 that protective cover 16 side plate front ends open.Double pendulum spare 17 and side plate turning cylinder 26 are below forward and backward support wheel 7,8 horizontal axis, and the arcuate groove 24 when being provided with two hinged components 23 and swing on protective cover interior plate top.This walking mechanism also can be used on other vehicle or the walking machine.
Power section comprises two motor---wheel hub motor and two pay motor 15 and accumulator etc.Main motor---wheel hub motor and driving wheel 6 are assembled into one, pay group of motors 15 and are arranged between the front and back two discharge opeings pressure supporting leg, and they carry out wobbling action to back row's hydraulic support leg synchronously by drive disk assembly.
Referring to Fig. 3, manipulation, control section are by a multinomial compound gauge tap 22, front limit chain rope 12, the spacing stay cord 13 in back, connecting rod 19 and their combineds effect such as pair group of motors 15, make seat lean forward, swing back and shift one's position.Combination switch 22 is arranged on the right side or the left side of armrest, and both sides can intermodulation.The advancing of combination switch 22 control wheelchairs, retreat, about turn to, lean forward, functions such as layback, speed governing, brake; Can also cooperate mouse to operate.
Front and back check chain rope the 12, the 13rd, the control part, their interaction locks the position of seat when static state, the length of supporting leg 1,2 and the angle of seat before and after dynamically the time, adjusting, their upper end is separately fixed at below the seat on the reference point, the lower end of front and back check chain rope 12 is through front-seat supporting leg lower end, behind front jocket wheel 9, be fixed on the supporting leg 2 of back again.The lower end of back check chain rope 13 is before guide wheel is fixed on the supporting leg 1.When the change in location of control seat, an end hinge of backrest angle is on the cylinder body of front leg strut 1, and other end hinge is in the downward part of backrest, and its action is to change automatically with the swing of preceding supporting leg, to adjust the inclination angle of backrest.
When occupant's needs are mobile, at first the main switch of power supply is opened, make wheelchair begin to travel forward, regulate the speed if desired, promote to adjust switch with thumb, make it to reach ideal scanning frequency.When the place ahead runs into barrier and ditch, suitably slow down, reduce and impact, the barrier or the ditch of the following height of horizontal axis of highly low front jocket wheel 9 can independently be climbed up or cross to electric wheelchair.Top bar more or during the abrupt slope as need, do not feel well in the place ahead of crawler belt or have when dangerous, Push switch 22, make pay group of motors 15 simultaneously forward rotation back hydraulic support leg 2 is swung is forward made it to lean forward by drive disk assembly.When they lean forward, the length of front limit chain rope 12 dependent segments is changed, the piston of supporting leg 1 falls before forcing; The length of back check chain rope 13 dependent segments also changes.Preposition piston presses down, make hydraulic refrigerant in the cylinder through pipe fitting and liquid storage cylinder 5 after, flow in the supporting leg cylinder rearwards, and the piston jack-up that makes progress, their variation length is identical.So just make the center of gravity and the position of seat flat to reach gradually, the action that after the occupant feels comfortably cool and be safe, stops to lean forward from the layback state.Whole process can continue up under the state that does not stop that slows down, and no longer swings by control piece locking double pendulum spare 17.When electric wheelchair is up to as shown in Figure 2 position, open double pendulum spare position local device, front and back support wheel 7,8 changes the original position state automatically with the variation on ground.Their adjacent front jocket wheels 9, back guide wheel 10 also and then link and change original position.Under the cooperation of crawler belt, smooth transition is to flat shape ground in continuing to advance to make electric wheelchair, and then the position of adjusting seat closes that center of gravity is follow-up to continue into, and this process is fit to when getting out of a predicament or an embarrassing situation too.
When advancing on the out of doors rough bad road conditions, support wheel at random 7,8 and liquid storage cylinder 5 in the walking mechanism just begin to bring into play its effect.Because support wheel 7,8 during with double pendulum spare 17 swing, does not lose supportive, when running into barrier or ditch, the position that this skidding is walked mechanism is raised as one-sided, and seat does not change; The piston rod of this side is forced to press down, and reduces bearing height.Because the volume of front and back two cylinders equates that the hydraulic refrigerant when piston rod presses down is got in the liquid storage cylinder, spring or compressed air in the liquid storage cylinder are compressed.After surmounting obstacles, hydraulic refrigerant is pushed again under the effect of elastic force or expansive force and gets back in the former cylinder.Like this, the belt electric wheelchair horizontal 20 ° with the interior gradient, or, adjust relative position voluntarily because of one-sided barrier causes less than 20 ° during with interior inclination, make seat keep level to advance basically.In advancing, the liquid storage cylinder can play damping effect again.
