Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a bicycle with both pedal driving and potential energy driving comprises a frame 1 and wheels 2, wherein a pedal device 3 is disposed on the frame 1, the pedal device 3 drives a first flywheel 5 to rotate clockwise through a first chain 4, the first flywheel 5 drives the wheels 2 to move forward, a seat 6 capable of moving up and down is disposed on the frame 1, the seat 6 moves downward under the action of the weight of a human body, the seat 6 drives a first gear disc 7 to rotate clockwise when moving downward, the first gear disc 7 drives a second flywheel 9 to rotate clockwise through a second chain 8, the second flywheel 9 drives the wheels 2 to move forward, the seat 6 resets upward under the elastic force of an elastic member, the seat 6 drives a second gear disc 10 to rotate clockwise when resetting upward, the second gear disc 10 drives a third flywheel 12 to rotate clockwise through a third chain 11, the third flywheel 12 drives the wheels 2 to move forward, the first flywheel 5, the second flywheel 9 and the third flywheel 12 are all driven in one direction with the same driving direction with the wheel 2.

The seat frame is characterized by further comprising a limiting sleeve 13 and a lifting rod 14, the limiting sleeve 13 is fixed on the frame 1, one end of the lifting rod 14 is connected with the seat 6, the other end of the lifting rod 14 is inserted into the limiting sleeve 13, the lifting rod 14 can axially slide along the limiting sleeve 13, and an elastic component is arranged between the lifting rod 14 and the limiting sleeve 13. When a person sits on the seat 6, the lifting rod 14 is pushed by the weight of the person to move downwards along the limiting sleeve 13, and when the user steps on the pedal device 3 on a bumpy road, the seat 6 is reset upwards by the elastic component. The seat 6 can move up and down repeatedly during the running process of the bicycle, and can be driven by potential energy continuously.

A strip-shaped hole 15 is formed in the surface of the limiting sleeve 13, a connecting rod 16 which is inserted into the strip-shaped hole 15 and slides along the strip-shaped hole 15 is installed on the lifting rod 14, and the connecting rod 16 is connected with one end of the limiting sleeve 13 through a first spring 18. Through setting up bar hole 15 and connecting rod 16, can make connecting rod 16 slide along bar hole 15, play certain limiting displacement. The lifting rod 14 and the seat 6 are prevented from deflecting during the up-and-down movement, and the comfort of the user is prevented from being influenced. The first spring 18 pulls the connecting rod 16 upwards, so that the connecting rod 16, the lifting rod 14 and the seat 6 are driven to return upwards, and the seat 6 is damped.

An annular sleeve 17 is sleeved outside the limiting sleeve 13, the annular sleeve 17 is fixed on the connecting rod 16, a fixed sleeve 19 is fixed at the other end of the limiting sleeve 13 through a bolt, and a second spring 20 is arranged between the annular sleeve 17 and the fixed sleeve 19. The second spring 20 exerts an upward force on the annular sleeve 17, causing it to return, while acting to damp the seat 6.

The first gear wheel 7 is arranged on one side of the lifting rod 14, the second gear wheel 10 is arranged on the other side of the lifting rod 14, and the first gear wheel 7 and the second gear wheel 10 are both arranged on the frame 1 through bearing seats. A pinion of the first gear disc 7 is meshed with a toothed plate on one side of the lifting rod 14, and a gearwheel is meshed with the second chain 8; the pinion of the second gear wheel 10 is engaged with the toothed plate on the other side of the lifting rod 14, and the bull gear is engaged with the third chain 11. Because the two gear discs are respectively arranged at the two sides of the lifting rod 14, when the lifting rod 14 moves upwards or downwards, the rotating directions of the two gear discs are opposite, the two gear discs respectively drive the two flywheels to rotate, a unidirectional driving mode is adopted between the flywheels and the wheels 2, and the driving directions are the same. Therefore, during the downward movement of the lifting rod 14, one of the gear discs drives one of the flywheels to drive the wheels 2 to move forward, and during the upward movement of the lifting rod 14, the other gear disc drives the other flywheel to drive the wheels 2 to move forward.

The number of the strip-shaped holes 15, the number of the connecting rods 16 and the number of the first springs 18 are all a plurality, and the number of the strip-shaped holes 15, the number of the connecting rods 16 and the number of the first springs are equal to that of the first springs. The number of the strip-shaped holes 15, the connecting rods 16 and the first springs 18 can be set according to the requirement, but the number of the strip-shaped holes 15, the connecting rods 16 and the first springs is generally matched.

Ratchet mechanisms are arranged among the first flywheel 5, the second flywheel 9 and the third flywheel 12 and the wheel 2. The ratchet wheel is adopted to realize one-way driving, and mutual interference among different driving modes is avoided.

When a person rides a bicycle, the gravity of the human body is applied to the saddle of the bicycle, the human body always moves up and down due to the uneven road surface and the like, the energy of the up-and-down vibration of the human body is unfortunately lost, and the energy is converted into the power for driving the bicycle through the seat 6.

The pedal device 3 drives the first flywheel 5 to rotate through the first chain 4, and the first flywheel 5 drives the wheel 2 to move forwards, so that pedal driving is realized.

Under the action of the weight of a person, the seat 6 is driven to move downwards, the seat 6 pushes the lifting rod 14 to move downwards, the lifting rod 14 drives the first gear disc 7 to rotate through the toothed plate, the first gear disc 7 drives the second flywheel 9 to rotate, the second flywheel 9 drives the wheel 2 to move forwards, and driving is achieved when the seat 6 is driven to move downwards by potential energy. The second gear wheel 10 rotates in the opposite direction to the first gear wheel 7, and the third flywheel 12 rotates in the same opposite direction to the second flywheel 9. When the second flywheel 9 drives the wheel 2, the third flywheel 12 does not drive.

When the road bumps or a user tramples the pedal device 3, the seat 6 resets upwards under the action of the spring, the lifting rod 14 moves upwards, the toothed plate drives the second toothed disc 10 to rotate, the second toothed disc 10 drives the third flywheel 12 to rotate through the third chain 11, the third flywheel 12 drives the wheel 2 to move forwards, and the spring resets to drive the seat 6 to move upwards. At this time, the rotation direction of the first gear wheel 7 is opposite to that of the second gear wheel 10, and the rotation direction of the second flywheel 9 is also opposite to that of the third flywheel 12, so that unidirectional driving is adopted. When the third flywheel 12 drives the wheel 2, the second flywheel 9 does not drive. As shown in fig. 1, the wheel 2 is driven forward when it rotates clockwise.

Through the arrangement of the three flywheels, the potential energy drive and the pedal drive cannot conflict, the drive is kept independent when the seat 6 moves downwards and when the seat 6 moves upwards, and the condition that the bicycle is reversely driven when the seat 6 moves upwards is avoided. Through the cooperation of three flywheels, drive wheel 2 moves forward, has solved the not laborsaving problem inadequately of current bicycle drive mode.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
