Drive system 3 of the present invention mainly constitutes (referring to Fig. 5) by preceding chain 311, rear chain 312, preceding flywheel 321, rear flywheel 322, wheel flywheel 323, axis 331 and rear axle 332 etc.Said axis 331 adopts the bicycle rear axle structure of prior art; Said rear axle 332 adopts the tricycle rear axle combination of prior art, comprises backshaft skin, rear axle rod, bearing etc.Wheel flywheel 323 is installed on the rear axle 332.Locking after pulling out under the pedal system 1 trailing wheel cushion; Pedal through user; The wheel disc 13 of pedal system 1 flywheel 321, axis 331 and rear flywheel 322 before preceding chain 311 drives successively rotate; Rear flywheel 322 drives wheel flywheel 323 through rear chain 312 again and rotates, and then drives rear axle 332 rotations, and wheelchair is advanced forward as tricycle.
Drive system 3 of the present invention directly drives wheel flywheel 323 with common tricycle wheel disc through a secondary chain and rotates different; Innovative design of the present invention is: change a secondary chain drive structure into two width of cloth chains placed in-line drive mechanism; Be that wheel disc chain 311 before connected is connected on the preceding flywheel 321; Preceding flywheel 321 and rear flywheel 322 symmetries are installed in the two ends of axis 331; Rear flywheel 322 is connected on the wheel flywheel 323 through rear chain 312 again, and just preceding flywheel 321, rear flywheel 322 and axis 331 constitute the placed in-line drive systems of two secondary chains (referring to Fig. 6) as the middle transition body.Be characterized in along with mobile system 2 in inside and outside the moving of wheelchair, rear chain 312 only moves in wheelchair.Preceding chain 311 is fixed because of the distance of wheel disc and preceding flywheel 321 in moving, and does not therefore just have the problem of regulating.Rear chain 312 hangs on rear flywheel 322 and the wheel flywheel 323; The position of wheel flywheel 323 is fixed; But the distance between rear flywheel 322 and the wheel flywheel 323 has variation by a relatively large margin in moving process, and rear chain 312 length that promptly connect rear flywheel 322 and wheel flywheel 323 are dynamic changes, however; Because after a secondary chain is decomposed into two width of cloth chains; Adjustable chain length has also reduced 50%, thereby has reduced technical difficulty, and the chain that helps solving in the drive system 3 is regulated problem.
Chain automatic regulating system 4 of the present invention is meant under the prerequisite that does not change the chain length dimension, guarantees that locus between two flywheels that chain connects can do moving by a relatively large margin automatically.Said chain automatic regulating system is meant the chain regulator of rear chain; Mainly constitute (referring to Fig. 5 by straining pulley 41, track 42 and spring 43, spring pulley 44 and track assembly pulley 45 etc.; Clear for expressing, the track assembly pulley 45 among Fig. 5 is by moving in the track in the frame of broken lines of the left side), track assembly pulley 45 is identical with the pulley block structure of employing in the mobile system 2; But as movable pulley, and only used 1 group at this.Track 42 is connected to the support that extends below with the main body frame of wheel cushion below; As the straining pulley 41 of regulating part, its sprocket shaft, support are connected with track assembly pulley 45, and its gear teeth are connected with rear chain 312; And can move along the lower limb of track 42; Spring 43 upper ends are installed in the track upper end, and the lower end is connected to track assembly pulley 45 lower ends through being positioned at the spring pulley 44 of track 42 lower ends.When track 21 moves backward; Rear flywheel 322 shortens with wheel flywheel 323 distances gradually; The chain that is centered around rear flywheel 322 and wheel flywheel 323 upper sections shortens; But the length of rear chain 312 is constant, causes the chain of rear flywheel 322 and wheel flywheel 323 below parts elongated accordingly, lax, sagging.It is on any point above or below the two-wheeled that chain is stretching solving one of lax method of this part chain; The direction of pulling can be arbitrarily; But some places have requirement for the direction of pulling; When present embodiment spurred chain downwards, the position height off the ground of chain minimum point was not less than 150 millimeters all the time, spurred chain forward and was limited in the main body frame of taking turns the cushion below.In view of the above, the embodiment design is the direction pulling chain to oblique below inclination 20 degree.The method of pulling is to adopt chain regulator 4.Its operation principle is a straining pulley 41 and be centered around the chain of rear flywheel 322 with wheel flywheel 323 below parts and be connected; Straining pulley 41 moves to oblique below along track under the effect of spring 43 contractilitys, and chain is also hauled to oblique below by straining pulley 41 and moves; How much lax chain is; How many springs 43 just strains with it automatically, and when manpower spurs mobile system 2 forward (referring to Fig. 7), rear flywheel 322 moves to the A1 point from the A3 point; Manpower drives the resistance that straining pulley 41 overcomes spring 43 with chain, makes straining pulley move to the B1 point from the B3 point.A1, B1 point are respectively that mobile system 2 is in when riding the wheelchair state; Rear flywheel 322 and straining pulley 41 residing positions, the projection (meaning of Fig. 8, the expression of 9 dotted portions is identical therewith) of rear flywheel 322 before dotted portion is represented respectively to move among Fig. 7 and straining pulley 41 positions.
When mobile system 2 moves, converts into conventional wheelchair state backward (referring to Fig. 8); The reference position A2 point of a hypothesis of passing through in its process and the position B2 point of straining pulley 41; It is thus clear that when rear flywheel 322 moves to the A2 point, connect rear flywheel 322 and shortened with the one section chain in wheel flywheel 323 tops, the below is become the combination of rear flywheel 322 and straining pulley 41, straining pulley 41 and 323 two sections chains of wheel flywheel by 323 1 sections chains of rear flywheel 322 to wheel flywheel; Simultaneously also elongated than one section original chain; This moment, straining pulley 41 received the effect of spring force, moved to the B2 point from the B1 point to oblique below, and the one section chain in below is strained by straining pulley 41 automatically.
When mobile system 2 moves to the final position backward; Be that rear flywheel 322 moves to A3 point (referring to Fig. 7); Straining pulley 41 upwards moves to the B3 point, and this moment, rear flywheel 322 moved to the rear of wheel flywheel 323 from wheel flywheel 323 the place aheads, and the chain that connects rear flywheel 322 and wheel flywheel 323 sides top among Fig. 8 becomes among Fig. 9 the side-lower at rear flywheel 322; The chain that connects rear flywheel 322 and straining pulley 41 parts is still above rear flywheel 322 sides, and is and elongated.After rear flywheel 322 moves to wheel flywheel 323 rears, straining pulley 41 will overcome spring force and move to the B3 point to oblique upper, overcome spring force and come from promotion mobile system manpower backward.No matter rear flywheel 322 stops at the A1 point, when still stopping at the A3 point, all will track locks 23 be locked, otherwise can receive the interference of spring 43.
Of the present invention being further characterized in that, said foot-operated wheelchair also comprises a damping system 8, promptly under the constant situation of said wheelchair original structure, increases a damping system 8, comprises damping wheel 81 and damper regulator assembly 82.One end of damper regulator assembly 82 is connected with the main body frame of wheel cushion below; The other end is connected with damping wheel 81; The compression spring control of damping wheel 81 dampened REG Regulator Assemblies 82 can contact or disengage with axis 331, promptly can between two states, change (referring to Figure 10).Its effect is the same with the function of the health and fitness facilities of " the magnetic control bicycle " of prior art, " Exercycle " class, but is more suitable for using on ordinary days patient's rehabilitation training of wheelchair.When wheelchair as exercise bicycle when indoor exercise uses; At first rear chain 312 is removed; Through adjustment damper regulator assembly 82; Enforcement suitably contacts damping wheel 81 with axis 331 adjustment of damping wheel 81 directions and pressure (the compression spring effect of pressure dampened REG Regulator Assembly 82), and its pressure is regulated according to rehabilitation clients's strength.At this moment, step pedal, preceding chain 311 only can drive preceding flywheel 321, rear flywheel 322 and axis 331 and rotate; Because rear chain 312 has been removed; Rear flywheel 322 can only dally, and wheel flywheel 323 can not rotate, and wheelchair is also just as you were; But because axis 331 rotations need overcome the frictional force that damping wheel 81 contacts with axis 331, thereby played the effect of exercise bicycle.When not using the exercise bicycle function, adjustment damper regulator assembly 82 disengages damping wheel 81 and axis 331, and hangs up rear chain 312, can get back to conventional foot-operated wheelchair state.
