The use process comprises the following steps:
when the bicycle is ridden in a standing mode, two feet are respectively arranged on a left pedal 303-1 and a right pedal 303-2, when the left pedal 303-1 is pedaled backwards by the left foot, a chain 302 is pulled to drive a front chain wheel 301-2 at the front end to rotate anticlockwise and drive the right pedal 303-2 to move forwards, when the right pedal 303-2 is pedaled backwards by the right foot, the chain 302 is pulled to drive a front chain wheel 301-2 at the front end to rotate clockwise and drive the left pedal 303-1 to move forwards, so that the left foot and the right foot pedal alternately pedal backwards and forwards with force in a walking posture, the front chain wheel 301-2 can be driven to rotate backwards and forwards, the front chain wheel 301-2 simultaneously drives a chain wheel shaft 304 and a first bevel gear 305 to rotate backwards and forwards, when the first bevel gear 305 rotates clockwise, a second bevel gear 306-1 is driven to rotate forwards (assuming that the direction is the forward rotation in accordance with the rolling direction of the wheels), at this time, the first pawl 307-1 on the second bevel gear 306-1 is meshed with the first ratchet gear 308-1 to drive the transmission shaft 312 to rotate in the forward direction, meanwhile, the third bevel gear 306-2 rotates in the reverse direction, the second pawl 307-2 on the third bevel gear 306-2 slides on the first ratchet gear 308-1 and does not play a driving role, and the transmission shaft 312 drives the rear wheel to roll forward through the variable speed transmission mechanism to enable the bicycle to advance; when the first bevel gear 305 rotates counterclockwise, the above situation is reversed, and the second pawl 307-2 on the third bevel gear 306-2 engages with the first ratchet gear 308-1 to drive the transmission shaft 312 to rotate forward, and the second bevel gear 306-1 rotates in reverse direction, the first pawl 307-1 on the second bevel gear 306-1 slides on the first ratchet gear 308-1 without driving, and the transmission shaft 312 drives the rear wheel through the speed change transmission mechanism to advance the bicycle. Thus, the bicycle can be continuously driven to move forward by alternately pedaling the left pedal 303-1 and the right pedal 303-2 backwards.
When riding on the seat, two feet are arranged on the left pedal 311-1 and the right pedal 311-2, when the left foot pedal 311-1 is pedaled forwards by the left foot, the fourth bevel gear 309-1 is rotated in the forward direction, the fifth bevel gear 309-2 is rotated in the reverse direction by the fourth bevel gear 309-1 through the sixth bevel gear 310, the right foot pedal 311-2 is driven to rotate in the reverse direction relative to the left foot pedal 311-1, the fourth pawl 307-4 arranged on the fifth bevel gear 309-2 slides on the second ratchet gear 308-2 and does not play a driving role, meanwhile, a third pawl 307-3 arranged on a fourth bevel gear 309-1 is meshed with a second ratchet gear 308-2 to drive a transmission shaft 312 to rotate in the forward direction, and the transmission shaft 312 drives a rear wheel to roll forwards through a variable speed transmission mechanism to enable the bicycle to advance; when the right foot is used for pedaling the right pedal 311-2 forwards, the situation is opposite to the above situation, at this time, the fifth bevel gear 309-2 rotates forwards, the fifth bevel gear 309-2 enables the fourth bevel gear 309-1 to rotate reversely through the sixth bevel gear 310, the left pedal 311-1 is driven to rotate reversely relative to the right pedal 311-2, the pawl 307-3 arranged on the fourth bevel gear 309-1 slides on the ratchet gear 308-2 without driving, meanwhile, the fourth pawl 307-4 arranged on the fourth bevel gear 309-2 is meshed with the second ratchet gear 308-2 to drive the transmission shaft 312 to rotate forwards, and the transmission shaft 312 drives the rear wheel to roll forwards through the variable speed transmission mechanism to enable the bicycle to advance. Thus, the left pedal 311-1 and the right pedal 311-2 are alternately pedaled forwards to reciprocate within a certain angle, and the bicycle can be continuously driven to move forwards. The seat can move back and forth, and the angles of the backrest and the headrest can be adjusted, so that different sitting postures can be conveniently changed. Under the condition that the steering effect is not influenced, the handle shaft of the steering mechanism can be stretched and stretched, and the front and rear inclination angles can be adjusted at will so as to meet different riding posture requirements.
The bicycle driving mechanism provided by the invention has a reasonable and novel structure, can randomly switch pedaling modes and randomly change various riding postures in the riding process, can improve the riding experience of riders, and enables the riders to be full of fun in riding; because the bicycle driving mechanism adopts a reciprocating pedaling driving mode, compared with the traditional circular motion pedaling mode, the bicycle driving mechanism has the advantages that the range of the up-and-down motion of the feet and the legs is smaller, a wide and comfortable seat can be equipped, the leg force generation is not influenced even if the bicycle driving mechanism adopts a lying riding posture, the riding comfort is greatly improved, the bicycle driving mechanism also has the characteristics of high transmission efficiency, no driving force generation dead point, strong climbing capability and the like, the comfort is high, fatigue is not easy to generate, the endurance mileage is favorably improved, and the bicycle driving mechanism is particularly suitable for long-distance riding; the application has the advantages of simple structure, strong practicability and simple operation and is worth popularizing.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several variations and modifications without departing from the concept of the present invention, and these should be considered as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
