Description
The utility model relates to a kind of actuating device of reciprocal pedal-type human powered vehicle.
For a change there is the motion dead point in the conventional drive form that scrunches in the circumference mode of human powered vehicle such as bicycle, three-wheel vehicle and the drawback such as unreasonable of exerting oneself, and existing many employings back and forth scrunch the report of mode bicycle driven, three-wheel vehicle and four-wheeled.As Chinese patent open (announcement) number be 86204872,87207547, documents such as CN2187141Y, CN 2113238U are introduced all is these type of technical schemes.But the reciprocal military stepping movement that it adopted in fact just changes traditional circular movement and is the multi-form arc of being done along the part circumference and lives reciprocating cutter.Test results shows, though the stepping movement of this arc can overcome the motion dead point that exists in the circular movement, but investigate from the mechanical structure angle of man-machine complex, still be not the best to bring into play the mode of motion that people's shank scrunches power, and the crank motion that carries out on rectilinear direction is only the suitable exercise mode that more meets man-machine mechanics rule.
The purpose of this utility model be at above-mentioned situation provide a kind of can be by the human powered vehicle actuating device of the reciprocal stepping movement of straight line that more meets man-machine mechanics rule.
In the structure of the actuating device of the reciprocal pedal-type human powered vehicle of the utility model, pedestal is provided with by the sprocket wheel that back and forth scrunches mechanism's drive, and drives the flywheel of wheel through chain drive by it.Wherein, the pair of parallel back vent body that is used to assemble rear wheel by lock piece bonded assembly front supported beam and rear end in the warp constitutes pedestal.Middle part at pedestal is provided with the imput shaft that can drive sprocket rotation through supporting structure.Be provided with the overrunning clutch mechanism of a pair of unidirectional drive on this imput shaft in mode axially arranged side by side, this two overrunning clutch mechanism also is combined with driven wheel in the mode that is connected respectively.Be provided with the slide mass that scrunches structure being combined with respectively through connection structure on two guide frames about horizontally disposed through supporting structure on the pedestal.Be respectively arranged with on this slide mass can with the tooth bar of the driving gear crop rotation engagement fit of its place side.The rear end of two tooth bars rope class through matching with steering structure, or flexible connection body commonly used such as chain connects.Said this steering structure can adopt simple pulley mechanism commonly used, is arranged on the pedestal through connection structure.
Structure is appreciated that the reciprocal stepping movement when therefore driving is carry out because the structure that scrunches that people's pin is trampled is arranged on along on the slide mass of horizontally-guided structure motion on the rectilinear direction of level thus.Cooperates do transmission with the engagement that can drive between the gear that imput shaft rotates by this slide mass institute bonded assembly tooth bar, drive and imput shaft bonded assembly sprocket rotation, by chain propulsive effort is passed to the flywheel of drive wheel again.Since about the rear end of two driving racks connect through steering structures such as pulleys by flexible connection body, when the left side was scrunched forward, the right side moved to ready position naturally synchronously backward; When the right side was scrunched forward, the left side is motion backward synchronously naturally again, returns back to ready position.Motion and so forth.This version is not only simple and convenient, and the rotating manner of rack and pinion helps improving mechanical rotation efficient.For improving through the stability of flexible connection body bonded assembly two tooth bars when reciprocating, can be connected with appropriate form between two tooth bars can make this flexible connection body keep the balance tension structure of tensioning state, as, can be between the front end of two tooth bars and pedestal framing member such as bonded assembly extension spring respectively.For making things convenient for the stepping movement of people foot, two scrunch structure and all be connected in form on the connection structure in hinged way for well about said.
For improve guaranteeing the intensity and the stability of the guide frame that stepping movement carries out along straight line, said this two guide frame all can adopt the version that is made of parallel two pilot bars.
With the realistic model of man-machine mechanics, bicycle that adopts the utility model said structure and the performance that the bicycle that adopts the conventional drive structure carries out have been carried out the contrast test test, the result can see table.
| The contrast test project | The utility model actuating device | The conventional drive mode |
| The human body thermal power transfer is the efficient (%) of mechanical energy | 77.7 | 25.4 |
| Mechanical energy driving efficiency (%) | 90～95 | 54～57 |
| The average thermal energy consumption of people's car (kilocalorie/kilometer) (ride speed and be 20 kilometers/hour) | ～5.9 | ～30.69 |
| Average short time (about 1 minute) maximum accelerating power | 〉=1 horsepower | ～0.2 horsepower |
| The highest riding speed (kilometer/hour) | ≥45 | ～20 |
After above-mentioned test result showed employing the utility model actuating device, the performance of each side all was better than traditional type of drive greatly.
Below foregoing of the present utility model is described further with example shown in the drawings.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.
