A kind of multiple-unit man-power bicycle

The present invention relates to bike tech, particularly a kind of bicycle with multiple manpower drive source.

Existing bicycle is a fixing body frame structure for automotive normally, and it passes to the transmission mode that rear main wheel makes it to rotate by foot-operated (or handle) crank by chain pull, and the drawback of this fixedly body frame structure for automotive and transmission mode is:

1, foot-operated (or handle) moment is cyclical variation in crank one revolution, in quite a few time, pedal moment is not in maximum or big position, according to calculating, the efficient of this transmission mode has only about 50%, has the power about half not obtain performance.

2, existing foot-operated (or handle) structure or shank disabled person's inconsistent use inconvenience to both legs length;

3, limit shank and pedaled giving full play to of power, increased the degree of fatigue of human body;

4, because human body is exerted oneself, bicycle travels forward, the friction force of road.Brake weight in advancing, road uneven, the various power that a variety of causes such as gravity center of human body's variation produce all act on vehicle frame or the tire directly or indirectly, cause the accelerate the failure of vehicle frame or tire, and the potential energy that these power produced can't be used also.

For this reason, the objective of the invention is:

1, improves the driving efficiency of bicycle, foot-operated (or handle) is in a drive cycle on the best acting position all the time;

2, alleviate the bicycle on the go as much as possible because vehicle that various power brings and tire failure;

3, utilize the caused potential energy of bicycle on the go motive power to change as much as possible, making wherein, a part is converted into the propulsive effort that bicycle advances;

4, change foot-operated (or handle) structure, make both legs length inconsistent or shank is disabled can manipulate easily per capita;

5, the power of pedaling (pulling force) of shank (or arm) is given full play to, reduced the degree of fatigue of human body;

The object of the present invention is achieved like this:

1, the present invention adopts four bar body frame structure for automotive, see that (Figure 11) reaches (Fig. 1), promptly be hinged and form by AB, BC, AD, CD four bars and spring antivibration device (6), the curved fire of AB bar is upper arm vehicle frame (9), the curved fire of BC bar is perpendicular arm vehicle frame (5), the curved fire of AD bar is underarm vehicle frame (8) and back underarm vehicle frame (8A), the CD bar is hinged by D point and underarm vehicle frame (8), by the C point with erect arm vehicle frame (5) and be hinged, spring is kept away the product that shake (6) upper end and is hinged with upper arm vehicle frame (9) rear lower, and the lower end is hinged with back underarm vehicle frame (8A);

Because AB, BC, AD, none is to decide bar for CD four bars, all belong to hanging stick, so any bar moves, other each bar all produces the travel motion that involves, the plane rotation motion of each bar had both influenced other bars, influenced by the plane rotation motion of other bars, constitute the plane rotation motion of four bar circulation comprehensives influence in the turning circle thus, wherein the CD bar is not done curved fire and is connected outward, it is a follower lever, it is the inside connecting rod of four-bar mechanism, other three bars are all done curved fire and are connected outward, accept external force and drive, they are former moving bars, and its curved fire arm is the hold-down arm of body frame structure for automotive, it is again the motion actuating arm of four-bar mechanism, the BC bar is done the double end curved fire and is connected outward in three former moving bars, and all the other two bars are done that the single head curved fire connects outward and be situated between by spring antivibration device (6) to connect the strain elastic element that changes as balance external force between its curved fire arm, and intensity that its bullet becomes and helical pitch are the master of the rigidity of four bar vehicle frame planes migration gyroscopic movement and the traverse factors of determining.Truly pedal in the process of riding at bicycle, see in (Fig. 1) stressed arrow 1. → be that human body is pedaled and being stepped on motion and the center of gravity creep takes place and make upper arm vehicle frame (9) produce stressed variation; Stressed arrow 2. → be that human body is pedaled and stepped on when motion arm perpendicular arm vehicle frame (5) upper end is produced the stressed variation of push-and-pull; Stressed arrow 3. → be that front-wheel is obstructed or perpendicular arm vehicle frame (5) lower end is produced impact during Front brake; Stressed arrow 4. → be in the traveling process, road is uneven to produce the stressed variation of inertia impact to perpendicular arm vehicle frame (5) lower end; Stressed arrow 5. → be in the traveling process, road is uneven to produce the stressed variation of inertia impact to back underarm vehicle frame (8A); Stressed arrow 6. → be that trailing wheel is obstructed or when brake back produces impact to back underarm vehicle frame (8A); Above-mentioned when being subjected to force direction identical with the direction of arrow, the power value that four bar vehicle frames pass to spring antivibration device (6) on the occasion of, spring is done the compression reaction, directly cause stress increase to compelling force value balance till, underarm two vehicle frames (9) (8A) do to close up motion on this moment.When being subjected to force direction opposite with the direction of arrow, the stress value of spring antivibration device (6) is a negative value, and spring is made release reaction, directly cause stress reduce to outer when unloading power value balance till, underarm two vehicle frames (9) (8A) are made opening movement on this moment.The embedding hinge is converted to unidirectional rotary motion at the component transmission arm (7) of upper arm vehicle frame (9) and the component recurrence device that is assembled in the underarm vehicle frame transmission gearbox (2B) with the opening and closing gyroscopic movement, above-mentioned idle work is converted into rotor inertia input accumulator determines that according to traveling state of vehicle storage still is added on the drive torque by it, the above-mentioned absorption that is four bar vehicle frames to all kinds of idle works, transmit, be converted to the working process and the principle of useful work.

When rear wheel brake, crop rotation clockwise direction motion down behind the tight bolt of back brake transmission body (17), and by flexible element (10A) traction upper arm vehicle frame (9) revolution that descends rapidly.During current wheel brake, perpendicular arm vehicle frame (5) lower end is turned round backward by four-bar mechanism (vehicle frame) degreeof turn is amplified rear drive upper arm vehicle frame (9) revolution that descends rapidly, when so front and back wheel is obstructed or is braked, four bar vehicle frames all directly utilize idle work to drive cushion to descend and impel the gravity center of human body to descend to shorten the both feet distance that lands, help the performance of human body safety measure action, because four bar vehicle frames have bigger deformation traverse when bearing the concentrated big load of unexpected generation, make the time expand of momentum, moment impact stress diminishes, make its power value and produce vehicle frame plastic deformation, the front fork fracture, the critical force value ratio that phenomenon such as turns over before people's car increases, thereby reduce the possibility of its generation, avoid simultaneously braking suddenly contact position, hour wheel road because of friction force less than inertial impact force, and generation tire surface cliding friction, because of moment the high temperature local melting friction coefficient is reduced sharply lose original friction force and causes parking period, the elongated phenomenon of distance, this is how four bar vehicle frames provide low center of gravity, few destruction, short time, short range, working process and principle that safety and comfort are stopped.

See when convex Lu Wusu is met in Figure 11 front-wheel wheel kinematic pair contact position, road (K), the perpendicular arm vehicle frame (5) of front-wheel (3A) is held up upward movement, the BC bar is that scope hinge (A, D point has trace migration, and it non-ly decide hinge) drives AB, CD two bars are done the anticlockwise direction migration and turned round with 2 of AD, AB bar curved fire arm upper arm vehicle frame (9) is done to turning down, do compression reaction that spring antivibration device (6) is unbalance, this moment, people's car weight heart descended; If when meeting spill road element, the unbalance release reaction of doing of spring antivibration device (6), people's car weight heart are then done to rise and are regulated; When convex road element is met in kinematic pair contact position, rear wheel rotation road (G), trailing wheel (3) and back underarm vehicle frame (8A) are not held and are held up upward movement, the AD bar is that hinge is done the cw revolution with A, comprehensive 2 of A, the C of driving draws close migration, 2 works of B, C are away from migration, it serves as the migration hinge with the A point that its result makes AB bar curved fire arm upper arm vehicle frame (9), work is to turning down, make the unbalance generation compression of spring antivibration device (6) reaction, the corresponding decline of people's car weight heart, during in like manner as if chance spill road element, spring antivibration device (6) then produces release reaction, the corresponding rising of people's car weight heart.Therefore, four bar body frame structure for automotive can utilize idle work to drive the locus of mediator's car weight heart, make it vehicle and can be similar to the straight-line track of maintenance.Because the derivative result of These characteristics of four bar body frame structure for automotive adopts the entity tire of thin light, compare with existing air-inflation tyre, it is all beneficial to sensitieness, the accuracy that improves idle work conversion using rate and conditioned reaction, and this has illustrated that four bar vehicle frames to vehicle wheel ground kinematic pair contact conditions improvement take place and change has produced vital function.

2, a component is set and returns device, see Fig. 4, it comprises a component transmission arm (7) chimeric with upper arm vehicle frame (9), have at least one or more tooth bar (7A) to reach and above-mentioned tooth bar ingear overrunning clutch mechanism and accumulator (18), above-mentioned component transmission arm is driven tooth bar to move up and down to convert to and unidirectionally rotatablely moves continuously, and be stored in clockwork spring (the 7D ') lining of accumulator (18), discharge then and superpose and be converted into wheel rolling movement forward;

Said accumulator (18) is formed by returning bevel gear (7D) clockwork spring (7D ') rubbish one-way clutch wheel (7CD), returns bevel gear (7D) and drives and tighten clockwork spring (7D '), clockwork spring (7D ') and promote one-way clutch and take turns (7CD) and make unidirectional continuous rotation and be superimposed on wheel to travel forward.

Now also further structure of the present invention and principle of work are described in conjunction with the accompanying drawings by embodiment.

Example 1: see Fig. 1, Fig. 2, Fig. 3, Figure 11, it comprises four bar vehicle frames, foot-operated, transmission device, component returns device, four bar vehicle frames are by AB, BC, CD, AD is hinged and forms, (as Figure 11) foot-operated (1) is pressed Fig. 5 and is constituted, can do the 360 any angles of degree and flexible up and down adjustable affixed with the rolling arm of force (1A), the rolling arm of force (1A) is pedaled up and down in foot-operated (1) and is stepped on when motion along runner movement (Fig. 2), drive that unidirectional driving wheel (11 ') and (11 ") are rotated and will pedal up and down by flexure member (10) and stepping on motion and become unidirectional continuous rotation; by drive link (4) bevel gear (4B) is passed in rotation then and be engaged with and promote wheel and advance; and component returns the tooth bar (7A) of device and (7A ') and by one-way clutch gear (7B) and (7C) up-and-down movement of tooth bar is transformed into unidirectional rotary motion, reach (11 ") by bevel gear (11 ') then and mesh to be added to and advance on the wheel by one-way clutch bevel gear (4D) by the overriding clutch coaxial (4C) with it.

Example 2: see Fig. 6, this example is actually on the basis of example 1 and increases by one and grade setting device (see figure 10) is arranged it is by adjusting the gear shift of handle (14C), makes final gear by different Jie's gears mesh and Jie's gear and gear meshing stepping a grade change speed be arranged.

When governor handle among the figure (14C) present position was 1 grade (slow shelves), the torque of final gear (11C) was passed to gear (4A ') by Jie's gear (11C-4A ') engagement and is done reduction of speed output.

When governor handle (14C) is transferred a gear left, promptly during neutral gear, Jie's gear (11C-4A ') and gear (4A ') are thrown off diaxon and are not correlated mutually.

When governor handle (14C) being transferred a gear i.e. Jie's gear (11B-4A) and gear (4A) engagement during 2 (fast shelves) left again, the moment of torsion of gear (11B) is passed to gear (4A) do raising speed output.

Example 3: see Fig. 7, Fig. 8, Fig. 9

This example is that with the different of example 1 it only moves through flexure member and overdrive clutch gear with a final gear (11A) riding to pedal up and down to step on, Jie's gear changes over and unidirectionally rotatablely moves continuously, and in component recurrence device, be provided with accumulator, it comprises biconial wheel (12) also to be provided with automatic stepless speed-regulating device (Fig. 8), friction wheel (13A), the friction pressing mechanism, friction wheel (13A) is under the effect of friction pressing mechanism, in biconial wheel, make the two-wire rolling touch with it, spring (13B) is embedded on the spring tray (13C), friction wheel (13A) is gone up mobile in the path or the big footpath of biconial wheel (12), make automatic stepless speed-regulating, output wheel (13) be positioned at below the spring tray (13C) and with rub that to examine wheel (13A) coaxial.

Friction pressing mechanism (see figure 9) comprises and adds the wheel (16) that bears down on one, roof pressure groove (16A), top wheel carrier (16B), pressing spring (16C), pressure-bearing frame (16D), add the wheel (16) that bears down on one, be positioned at the below of the roof pressure groove (16A) of transmission case body, itself and top wheel carrier (16B) are formed one, top wheel carrier (16B) lower end bifurcated is striden the upper end of two pressing spring (16C) that are embedded in friction wheel (13A) front and back end, the lower end of pressing spring (16C) and pressure-bearing frame (16D) are chimeric, 2 on pressure-bearing frame (16D) respectively with the front and back end of friction wheel (13A) siamesed rolling screw body outside the garden do to roll and be combined into one, friction wheel (13A) is pressed against the middle top of 2 bevel wheeies (12).

The accumulator that component returns device is the change that is used for being subjected to when vehicle frame accidental shock or road kinematic pair, brake etc. impels four bar hinge vehicle frames to do the moment of opening and closing campaign, the potential energy that external force is caused changes in the clockwork spring that is stored in the accumulator, discharges gradually then to become to make to promote the power that wheel advances.

Running into upward slope or other reasons in cyclery causes trailing wheel rolling moment of torsion to become big, and combine for rolling screw between friction wheel (13A) and output gear (13) axle, its conduction nominal torque is to lean on the pressure of spring (13B) that balance is provided, at this moment, spring (13B) is not enough to balance trailing wheel moment of torsion, so the clickwise of friction wheel (13A) can not drive the rotation of output gear (13), because output gear (13) is static, therefore the friction wheel (13A) that is rotating is promptly along the screw shaft of output gear (13), miner diameter end direction precession to bevel wheel (12), until spring (13B) shorten because of compression pressure increase to the trailing wheel equilibrium of torques till, because the miner diameter end linear velocity of bevel wheel (12) is littler than bigger diameter end, thereby obtain the transmitting ratio of high pulling torque jogging speed, make driving link foot-operated (1) keep its constant stress value, adapted to the laborsaving requirement when going up a slope.When the bicycle descending or enter smooth ground, its trailing wheel rolling moment of torsion diminishes, because of rolling Luo Xuan body driving efficiency height, do not produce self-locking, characteristics that can positive and negative conduction, spring by compression (13B) potential energy is pushed friction wheel (13A) rotation to the bigger diameter end direction of bevel wheel (12), thereby it is fast to obtain linear velocity, and the transmitting ratio of little moment of torsion makes driving link, foot-operated (1) keeps constant stress value, has adapted to descending or the smooth ground-surface speedup demand of riding.Regulating handle (13D) is by regulating spring (13B) precompressed compression, and the stressed rated value of foot-operated to change (1) is pedaled the needs of stepping on adjusting to adapt to different dynamics.

In this example, we are provided with two bevel wheeies (12) (12 '), in fact, also can only establish a bevel wheel and make friction wheel (13A) transmission of pressurizeing in the above, also can realize above-mentioned functions

Example 4: referring to Fig. 9 and Figure 14, it comprises four bar vehicle frames, foot-operated, (or handle) transmission device, component returns device, as example 3, but different with it is, it adopts foot-operated (or handle) to drive the driving wheel rotating manner by the inflexibility member, specifically it is the rolling screw bar structure of revolving by about 4, foot-operated (or handle) converted to along pumping of rolling screw bar two-wayly rotatablely move continuously, pass to overrunning clutch mechanism through the finishing bevel gear cuter that is positioned at rolling screw bar top again and convert to and unidirectionally rotatablely move continuously; This frame mode also can change into by two single rotation direction rolling screw bars and add two chute-type mechanisms, promptly place foot-operated (or handle) two chutes to slide up and down respectively, thereby and singly revolve rolling screw and link to each other to bar and cause that two single rotation direction rolling screw bars do back and forth rotation with two, finishing bevel gear cuter by rolling screw bar top passes to overrunning clutch mechanism then, with two-way rotatablely move to change into unidirectionally rotatablely move continuously.

The present invention with the advantage that existing bicycle is compared is:

1, pedal in foot-operated (or handle push-and-pull) and step in the period of motion, foot-operated (or handle) is in all the time maximum and has an effect in the situation, and its transmission efficiency can exceed about one times than existing bicycle;
