Recover sport for the disabled's function and drive tricycle with two people

Affiliated technical field

This utility model relates to a kind of tricycle, especially have recover sport for the disabled's function, can drive people with disability such as hemiplegia and suffer from the tricycle manpower of limb motion or manpower and mechanomotive force hybrid power, that double rear wheel drives, that do not have " gear differential mechanism ", portable, two people driving.

Background technology

At present, known deflecting roller tricycle the preceding has rickshaw and motor vehicles two classes, the construction features of pedicab is the two ends that two trailing wheels are installed in same axletree, axletree connects with vehicle frame with bearing, the two trailing wheel installation method differences at axletree two ends, one rear flank wheel and axletree connect firmly axle and wheel with the form of key, can not relatively rotate, and opposite side trailing wheel and axletree link with rotating bearing, axle can relatively rotate with wheel, a driven sprocket and a band-type brake wheel are equipped with in the centre of axletree, when the people of steered vehicle steps drive sprocket by the driven sprocket on the chain drive axletree, axletree and driven chain rotate synchronously, and axletree also drives the wheel that connects firmly in axletree one side simultaneously and rotates, thereby starts tricycle.When the people of steered vehicle steps band-type brake, band-type brake wheel on the axletree is not changeed, thereby tricycle is braked, but also only connect firmly the wheel of a side on axletree and play braking action this moment, another wheel is inoperative in the same old way, so when car startup and car braking, forward and power backward all can not act on the symmetrical center line, certainly will produce a power that turns to a side, and this steering force is dangerous, because this turns to is that the driver is unwanted, the driver will be at this moment adds the power that turns to of preventing to handlebar, just can balance this harmful power, this to common do not have training just by bike people be difficult, this method is used in being not all right on the car that recovers sport for the disabled's function, and this design also designs for solving " differential " problem, must solve " differential " problem because two-wheel drives, though and single wheel drive does not have " differential " problem, produced the steering force problem of deleterious danger.Two-wheel drives " differential " problem of motor tricycle, solution is that two trailing wheels respectively are installed on one " semiaxis ", links with " gear differential mechanism " in the middle of two " semiaxis ", but " gear differential mechanism " can not be used on the light roadster because it too greatly, too heavy, too stupid, cost is too high.More than two kinds of tricycles all do not have healthy people and the common functions of driving of people with disability, the also function of people with disability not being recovered to move does not promptly drive the function of people with disabilitys' such as hemiplegia the passive coordination exercise of trouble limb.

Summary of the invention

In order to overcome existing tricycle does not drive people with disabilitys' such as hemiplegia the passive coordination exercise of trouble limb simultaneously in advancing function, easily produce side when reaching the single rear wheel driving and change power, when double rear wheel drives with the high deficiency of the too heavy cost of gear differential mechanism, this utility model provides a kind of recovery sport for the disabled function to drive tricycle with two people, this car is that the double rear wheel of gearless differential mechanism drives car, simple in structure, light, do not produce side in the motion and change power, drive easily, the carrying transportation function that has not only possessed common tricycle, main is that it has the function that can drive people with disabilitys' such as hemiplegia the passive coordination exercise of trouble limb in advancing, thereby reaches the purpose of recovering sport for the disabled's function.

The technical scheme that its technical problem that solves this utility model adopts is: the tricycle front-wheel is installed in the handlebar below, (on handlebar two handrails, rim brake before and after being equipped with, be the clear and distinctive emphasis of drawing, omit in the accompanying drawing and do not have picture,) two trailing wheels are installed in both sides, vehicle frame rear portion respectively, installation method is all identical with the bicycle rear installation method separately, all connecting firmly an override type sprocket wheel or override type cone pulley on two trailing wheels separately, on the two trailing wheel front frames, connect firmly main shaft on vehicle frame with the bearing supporting, a hand sprocket wheel or hand duplicate sprocket are installed on the main shaft upper frame, before the main shaft, a foot-operated sprocket wheel or foot-operated duplicate sprocket respectively are installed on the back vehicle frame, before hand sprocket wheel or the hand duplicate sprocket, a saddle respectively is housed on the back vehicle frame to be sat, connect firmly on the main shaft three whole sprocket wheels or three monoblock type cone pulleys are installed, also connect firmly on the main shaft one or two is installed, override type sprocket wheel or override type cone pulley, the monoblock type sprocket wheel at main shaft two ends or monoblock type cone pulley, each personal chain respectively with the vehicle frame rear portion, the override type sprocket wheel or the override type cone pulley that connect firmly on two trailing wheels are connected, the monoblock type sprocket wheel or the monoblock type cone pulley at main shaft middle part, with chain and hand sprocket wheel or hand duplicate sprocket, and the foot-operated sprocket wheel or the foot-operated duplicate sprocket at main shaft rear portion, three sprocket wheels link together, override type sprocket wheel at main shaft middle part or override type cone pulley, with forward foot-operated sprocket wheel of main shaft or foot-operated duplicate sprocket, link together with chain, the main shaft middle part is if load onto second override type sprocket wheel or override type cone pulley, this sprocket wheel is a standby sprocket wheel when adding mechanomotive force, during as if affix motor on the car or internal combustion booster, sprocket wheel on motor or the internal combustion booster, promptly be connected, thereby form the tricycle of manpower and mechanomotive force hybrid power by this second override type sprocket wheel on chain and the main shaft or override type cone pulley.Because monoblock type sprocket wheel or monoblock type cone pulley that the main shaft two ends connect firmly, the cone pulley sheet number of two sprocket wheels, corresponding each sheet number of teeth all equate, override type sprocket wheel that connects firmly on two trailing wheels or override type cone pulley, the cone pulley sheet number of these two sprocket wheels and corresponding each sheet number of teeth also equate, so can drive two trailing wheels when main shaft rotates rotates synchronously, this has just reached double rear wheel and has driven handy purpose simultaneously.And override type sprocket wheel that connects firmly on two trailing wheels or override type cone pulley---this " override type " divides the sprocket body characteristic to be: sprocket wheel can drive wheel and rotate, and wheel can change soon than sprocket wheel, and this is the rotational characteristic of " override type " sprocket wheel on the known bicycle rear.Exactly because this characteristic has been arranged, when turning, two trailing wheels of this utility model tricycle, the velocity of rotation of inboard wheel can be the velocity of rotation of override type sprocket wheel or override type cone pulley, override type sprocket wheel on the outboard wheels or override type cone pulley, with override type sprocket wheel on the inboard wheel is to rotate synchronously, but outboard wheels can be changeed soon than override type sprocket wheel or override type cone pulley, thereby " differential " method that nothing " gear differential mechanism " occurred, it is that the double rear wheel driving makes the portable purpose of car again that car is reached.Owing on the main shaft override type sprocket wheel or override type cone pulley can be installed, be connected with anterior foot-operated sprocket wheel of main shaft or foot-operated duplicate sprocket with chain again, this moment, this utility model can be pure rickshaw.If install second override type sprocket wheel or override type cone pulley on the main shaft, and when being connected with chain with the motor of extra affix or the sprocket wheel on the internal combustion booster, this utility model has just become car that manpower cooperates with mechanomotive force.Since the monoblock type sprocket wheel at main shaft middle part or monoblock type cone pulley with hand duplicate sprocket, and the foot-operated sprocket wheel at main shaft rear portion or foot-operated duplicate sprocket are with same chain connection the time, reserved differential seat angle, differential seat angle is that the right hand handle of hand sprocket wheel is in highest order when foot-operated left foot pedal during in highest order---be two-wheeled differs 180 degree.Be sitting on the anterior saddle is main the driving, his both hands handle, both feet step anterior foot-operated sprocket wheel of main shaft or foot-operated duplicate sprocket, by override type sprocket wheel or the override type cone pulley that connects firmly on chain and the main shaft, the drive main shaft rotates, and two branch roads passed to rotation again by main shaft, whole sprocket wheel or whole cone pulley that one of them branch road connects firmly by two ends on main shaft and the main shaft, reach chain and pass to override type sprocket wheel or the override type cone pulley that connects firmly on two trailing wheels, rotate thereby drive two trailing wheels.Another rotates branch road is by whole sprocket wheel or whole cone pulley and chain in the middle part of main shaft and the main shaft, pass to the foot-operated sprocket wheel or the foot-operated duplicate sprocket at hand sprocket wheel or hand duplicate sprocket and main shaft rear portion, three sprocket wheels rotate together, and these three sprocket wheels all are all-in-one-piece, so not only the whole sprocket wheel on the main shaft can drive the foot-operated sprocket rotation of hand sprocket wheel or hand duplicate sprocket and main shaft rear portion, otherwise shake hand sprocket wheel or hand duplicate sprocket, and step foot-operated sprocket wheel or foot-operated duplicate sprocket, main shaft also can be driven and be rotated, also can play and drive the purpose that wheel rotates, but can not controlling party to, so can only claim " copilot ", and copilot is to have dyskinetic people with disability, and the purpose that this moment, healthy people and people with disability drove in double harness is achieved.Again because copilot generally is people with disabilitys such as hemiplegia, we can will have other method of dyskinetic hands, making it a passive side handle of holding hand sprocket wheel or hand duplicate sprocket can not leave, other method of dyskinetic foot is arranged, make it passive and pedal foot-operated sprocket wheel or foot-operated duplicate sprocket one batter is pedaled and can not be left, handy hands is initiatively held the opposite side handle of hand sprocket wheel or hand duplicate sprocket, handy foot is initiatively pedaled the opposite side pedal of foot-operated sprocket wheel or foot-operated duplicate sprocket, when main shaft rotates, the whole sprocket wheel that connects firmly on the main shaft also can drive hand sprocket wheel or hand duplicate sprocket by chain, and sprocket wheel is ridden at the main shaft rear portion or foot-operated duplicate sprocket rotates together, again because hand sprocket wheel or hand duplicate sprocket are identical with the foot-operated sprocket wheel or the corresponding number of teeth of each sheet of foot-operated duplicate sprocket, link to each other with same chain again, so when foot-operated sprocket wheel left foot pedal during in highest order, allow the right hand handle of hand sprocket wheel in highest order, this outer corner difference can not change at the volley yet, so the trouble limb of copilot not only can be by passive drive campaign, and the form of motion pendulum right arm when lifting left lower limb when walking, the action of pendulum left arm and for similar when lifting right lower limb, be that coordination is constant, exercise through the long period, the passive exercise of suffering from limb has become active exercise gradually, and the people with disability suffers from the function of limb motion and just recovered.All realize to these whole purposes of design.

The beneficial effects of the utility model are, make tricycle many again one drive the people with disability and suffer from the function of the passive coordination exercise of limb, owing to adopted such scheme, the car that double rear wheel is driven is many again a kind of gearless differential mechanism, just can realize the method for differential, tricycle is better driven, lighter.Owing to adopted such scheme, can allow more people with disability recover motor function, make their life finer, allow them achieve more glorious results for motherland's construction, make motherland finer tomorrow.

The specific embodiment

In accompanying drawing illustrated embodiment one, wheel (14) is installed in the below of handlebar (12), two trailing wheels (1), (21) be installed in the both sides, rear portion of vehicle frame (13) respectively, its installation method is identical with the bicycle rear installation method, two trailing wheels (1), (21) all connecting firmly an override type sprocket wheel (25) on separately, (20), two trailing wheel front frames (13) are gone up and are being connected firmly a main shaft (5) with two bearings (the general code name of accompanying drawing middle (center) bearing is represented) supporting, a hand sprocket wheel (7) has been installed on main shaft (5) upper frame (13), main shaft (5) front portion, a foot-operated sprocket wheel (15) respectively is housed on the vehicle frame at rear portion (13), (23), before the hand sprocket wheel (7), a saddle (2) respectively is installed on the back vehicle frame (13), (9), connect firmly on the main shaft (5) three whole sprocket wheels (4) are installed, (11), (18), no matter " monoblock type sprocket wheel that what is called is connected static and dynamically down all with an axle relative fixed, and sprocket wheel and the synchronous rotation of axle dynamically the time." and an override type sprocket wheel (10) or two override type sprocket wheels (8); (10); " so-called override type sprocket wheel (25), (20), (8), (10) be meant the split type sprocket wheel that has now on the bicycle rear, sprocket wheel has Internal and external cycle two parts under static state, the endoporus and the wheel of inner ring are connected, two ratchets are housed on the excircle of inner ring, spring is arranged at the ratchet bottom, on the endoporus of outer ring single direction ratchet is arranged, be sprocket wheel on the excircle of outer ring, form the connection of rolling with ball between Internal and external cycle, dynamically down after the outer ring sprocket wheel is rotated, thereby the outer ring only can drive inner ring and rotate the rotation of drive wheel when the single direction ratchet work of ratchet and sprocket wheel inner ring, inner ring does not change during the outer ring backward rotation, ratchet slips on the single direction ratchet surface, it is that wheel does not change that inner ring does not change, otherwise under the situation that wheel rotates, the outer ring sprocket wheel is not driven when wheel drives the inner ring rotation, the rotating speed that is inner ring can surpass the outer ring rotating speed, so claim the override type sprocket wheel, this utility model has utilized this override type sprocket wheel characteristic exactly, the friction speed differential of two trailing wheels when realizing turning to." the whole sprocket wheel (4) at main shaft (5) two ends; (18) use chain (3) respectively; (19) with two backs (1); the override type sprocket wheel (25) that connects firmly (21); (20) link to each other; the whole sprocket wheel (11) at main shaft (5) middle part, with chain (22) and hand sprocket wheel (7) and foot-operated sprocket wheel (23), three sprocket wheels link to each other, the override type sprocket wheel (10) at main shaft (5) middle part links to each other with foot-operated sprocket wheel (15) with chain (17), main shaft (5) middle part is if install override type

(1), (21) on override type sprocket wheel (25), (20) of the identical number of teeth that connects firmly link to each other, rotate simultaneously so can drive two trailing wheels (1), (21) when main shaft (5) rotates, double rear wheel drives to be realized.Again owing to sprocket wheel (25), (20) are " override type " sprocket wheels, so when turning, though main shaft (5) can only drive (25), (20) two " override type " sprocket wheel rotates synchronously, but because the override type sprocket wheel on the known bicycle rear has the characteristic that can make wheel faster than sprocket wheel, faster so outboard wheels always can obtain velocity compensation than inboard wheel rotating speed, thus realize " differential ".If have only an override type sprocket wheel (10) to link to each other with foot-operated sprocket wheel (15) on the main shaft (5) with chain (17), this moment, this tricycle was pure rickshaw, if installed override type sprocket wheel (8) again on the main shaft (5), this standby sprocket wheel just can be attached thereto with chain with the motor that increases again outside the accompanying drawing or the sprocket wheel on the booster, and this moment, tricycle just became manpower to cooperate the vehicle of power with mechanomotive force.Be sitting on the saddle (9) is main the driving, his both hands buttress handlebar (12), both feet are stepped on the pedal (16) on the foot-operated sprocket wheel (15), when sprocket wheel (15) rotates, drive override type sprocket wheel (10) by chain (17), thereby driving main shaft (5) rotates, thereby drive the whole sprocket wheel (4) on the main shaft (5), (11), (18) rotate, " split override type sprocket wheel (8) does not rotate " whole sprocket wheel (4), (18) again by chain (3), (19) the override type sprocket wheel (25) on drive two trailing wheels, (20) rotate, thereby drive two trailing wheels (1), (21) rotate, and whole sprocket wheel (11) can drive hand sprocket wheel (7) and foot-operated sprocket wheel (23) rotates simultaneously by chain (22), because that saddle (2) is gone up seat is the copilot, be that people with disabilitys such as dyskinetic hemiplegia are arranged, his handy hands is initiatively held the handle (6) on the hand sprocket wheel (7), his handy foot is initiatively pedaled the pedal (24) on the foot-operated sprocket wheel (23), and dyskinetic hands and foot are arranged is to make its passive opposite side hands (6) of holding hand sprocket wheel (7) with other method, the passive opposite side of pedaling on the foot-operated sprocket wheel (23) foot-operated (24), all can not leave, no matter so be that the master drives or copilot all can be by allowing hand sprocket wheel (7), the rotation of foot-operated sprocket wheel (23), driving copilot is people with disability's trouble limb passive exercise itself, again because hand sprocket wheel (7) is identical with foot-operated sprocket wheel (23) two teeth number of sprocket, and link to each other with same chain (22), so when dress chain (22), allow the left side pedal (24) of foot-operated sprocket wheel (23) when highest order, and allow the right side handle (6) of hand sprocket wheel (7) in highest order, this 180 degree differential seat angles can not become at the volley yet, and motion at this moment and people step left foot pendulum right arm when walking, and the sports coordination of pendulum left arm and periodically all closely similar when stepping right crus of diaphragm, and can not change, passive motion through secular this coordination, suffering from limb can change gradually, become active exercise by passive exercise, people with disability's motor function has also just been recovered at that time.When hand sprocket wheel (7) is initiatively shaken in copilot, when stepping foot-operated sprocket wheel (23), rotate by whole sprocket wheel (4), (18) that chain (22) drives on the main shaft (5), thereby drive override type sprocket wheel (25), (20) rotation by chain (3), (19), thereby drive two trailing wheels (1), (21) rotation, but rotate override type sprocket wheel (8), (10) that can not drive on the main shaft (5), this is the characteristic decision of override type sprocket wheel, this active for copilot is driven and has been alleviated load, thereby has also created the condition that makes things convenient for for suffering from limb recovery active exercise function.

In accompanying drawing illustrated embodiment two, be with all sprocket wheels (4) among the embodiment one, (7), (8), (10), (11), (15), (18), (20), (23), (25) ten sprocket wheels all are the situations of single sprocket wheel, changing a sprocket wheel or a plurality of sprocket wheel is duplicate sprocket or cone pulley, wherein can sprocket wheel (15) will be ridden, (23) and hand sprocket wheel (7) change into duplicate sprocket, can be with whole sprocket wheel (4), (11), (18) change into cone pulley, can be with override type sprocket wheel (8), (10), (20), (25) change into the override type cone pulley, a kind of and multiple speed can occur regulates, other structure connection and performance are all identical, the requirement of changing is: each sheet corresponding teeth number average of hand duplicate sprocket (7) and foot-operated duplicate sprocket (23) equates, and change simultaneously, whole cone pulley (4) and whole cone pulley (18), every pair of sprocket wheel of override type cone pulley (20) and override type cone pulley (25) are changed simultaneously and corresponding each sheet number of teeth all equates.
