Abstract
The invention relates to an equal-torque linear reciprocating manpower pedaling device which converts pedaling motion into circumferential motion, under the condition that force exerted on pedals by the feet is unchanged in direction and magnitude, torque acted on a driven wheel by the pedals can be kept unchanged by using rockers in a left double-rocker single-acting ratchet mechanism and a right double-rocker single-acting ratchet mechanism which are arranged on the pedaling device, and the length of the rockers is adjustable, so that the driven wheel evenly rotates through continuous, linear, reciprocating and alternating pedaling of the feet. The pedaling space of the manpower pedaling device is reduced, dead points are eliminated, pedaling efficiency is improved, and the rotating speed of the driven wheel is uniform. The manpower pedaling device can be widely applied to a bicycle, an electric bicycle and other devices needing manpower pedaling as power and is particularly suitable for occasions where the pedaling space is small and not suitable for the feet to do circumferential motion, such as a small-size electric bicycle, a supine or semi-lying riding bicycle, a sightseeing bicycle, a scooter, a manpower astatic type miniature electric car and others.
Description
Affiliated technical field
The present invention relates to a kind of pedal device such as manpower such as linear reciprocating such as moment such as grade that people's pedaling is converted into circular movement, this pedal device does not have dead point, particularly can act on treadle effort direction size constant in the situation that at pin, the torque keeping that pedal produces flower wheel is constant.
Background technology
Now widely used manpower pedal device, the pedal device that step circles mostly, as bicycle, the currently used manpower of Electrical Bicycle scrunches mechanism, and these pedal devices have a common shortcoming, and the moment producing while scrunching is exactly inhomogeneous, and there is a dead point, this not only makes circular movement inhomogeneous, and also can be because of dead point time, moment be zero, make flower wheel continuously motion be obstructed.
Summary of the invention
The moment producing while scrunching in order to overcome existing pedal device is inhomogeneous, and there is this shortcoming of dead point, the present invention can act on treadle effort direction size constant in the situation that at pin, utilize in the double rocking lever single action ratchet device of pedal device setting, rocking bar length can regulate automatically, the rocking bar arm of force is remained unchanged, thereby it is constant to make pedal act on the moment that rocking bar produces, the moment that flower wheel is produced is also just constant.The continuous linear of both feet scrunches toward complex Alternating, and double rocking lever just can drive driven crop rotation evenly to rotate under ratchet coordinates.
The technical solution adopted for the present invention to solve the technical problems is: the continuous linear of both feet scrunches pedal toward complex Alternating, act on treadle effort direction size constant in the situation that at pin, utilize the self-adjustable double rocker mechanism of rocking bar length, keep arm of force size constant all the time, thereby it is constant to make pedal act on the moment that rocking bar produces, the moment that flower wheel is produced is also just constant, does not also just have dead point, rocking bar drives ratchet, and ratchet drives driven crop rotation evenly to rotate.
The invention has the beneficial effects as follows: the present invention has reduced the space that scrunches of manpower pedal device, has eliminated dead point, has improved and has scrunched efficiency, makes secondary speed even.Can be widely used in bicycle, Electrical Bicycle and other need manpower to scrunch the mechanism as power, be particularly suitable for scrunching space less, be not suitable for the occasion that pin circles, as small size Electrical Bicycle, bicycle, outing vehicle, scooter, RV recreational vehicle that supine posture, semi-lying type are ridden, and miniature electric automobile that can manpower assistant etc.

Accompanying drawing explanation; The specific embodiment
Pedal device structure is symmetrical, by left slider A, and 2. left slider B, 3. left spring A, 4. left spring B, 5. left rocking bar A, 6. left rocking bar B, 7. left ratchet, 8. left sliding sleeve, 9. left-hand tread plate, 10. left locating dowel pin group etc. becomes the single-lift ratchet device of left side double rocking lever, by right slide block A, 12. right slide block B, 13. right spring A, 14. right spring B, 15. right rocking bar A, 16. right rocking bar B, 17. right ratchets, 18. right sliding sleeves, 19. right-hand tread plates, the single-lift ratchet device of the composition such as 20. right locating dowel pins the right double rocking lever.Left foot (25) is stepped on left-hand tread plate (9) moves it from the top down, masterpiece is for left-hand tread plate and pass to left rocking bar B (6), left rocking bar B produces moment to left ratchet (7), and left ratchet drives flower wheel (21) to rotate by follower shaft (22).In the time that left foot scrunches left-hand tread plate and moves downward to left locating dowel pin (10), left foot stops scrunching, at this moment left rocking bar A (5) moves downward in process and by left sliding sleeve (8) and driving lever (24), right sliding sleeve (18), right rocking bar B (15), right-side pedal (19) is brought to most significant bit, scrunching right-hand tread plate (19) followed by right crus of diaphragm (26) moves downward, and repeat prior process, go round and begin again.
Because mechanism is symmetrical, left rocking bar A and left rocking bar B, left slider A (1) and left slider B (2), when left spring A (3) designs with left spring B (4), size is the same, left slider A, left slider B can be along left rocking bar A, left rocking bar B axis slides, at left spring A, under left spring B combined action, left rocking bar B length can regulate automatically, make left-hand tread plate path of motion by a perpendicular bisector between left slider A and left slider B, thereby can act on treadle effort direction size constant in the situation that at pin, the torque keeping that pedal produces flower wheel is constant, as both feet ceaselessly up and down reciprocatingly scrunch, flower wheel will be made continuous uniform and rotate.
