Description

Bicycle with gravity driving device

The utility model relates to a kind of bicycle that has gravity driving device, and it mainly comprises bicycle rack, front and rear wheel, and handlebar, vehicle seat, and foot-operated driving system is formed.

Bicycle is a kind of with the manpower driving, and the light two-wheeled walking-replacing tool that is easy to drive.Since 18th century, people just constantly grope to manufacture experimently multi-form bicycle, but its driving method and device almost do not change.Because existing bicycle driving mode all relies on manpower to drive with riding, this type of drive mainly is the motion of shank big muscles, reaches under the situation of certain intensity riding, and can strengthen the aerobic metabolism function.But posture by bike is very unfavorable to the back activity, and the muscle of upper limbs can not get enough motions, the purpose of out of reach all round exercise health.

The purpose of this utility model provides a kind of conventional drive mode of both can having used to ride with regard to being to overcome above-mentioned weak point of the prior art, can rely on human body self gravity to drive again, make cyclist's health obtain the bicycle that has gravity driving device of all round exercise.

The purpose of this utility model can realize by following measure: on bicycle, also be equipped with one the cover by Hydraulic Pump, pressure lever, push away the gravity driving device that gear mechanism, ratchet and flexible restoring organ are formed; One end of pressure lever is hinged on the front portion of vehicle frame, and the other end combines by the flexible restoring organ under bearing pin and the vehicle seat; The upper end and the pressure lever of the piston rod of Hydraulic Pump are hinged, and the inner chamber of Hydraulic Pump is by hydraulic tubing and the intracavity inter-connection that pushes away gear mechanism; Push away on the chain stay that gear mechanism is installed in the cycle frame rear lower; Ratchet is installed in a side of rear wheel hub.

Lay a spring in the cavity of Hydraulic Pump that bicycle of the present utility model adopts; Push away on the piston rod of gear mechanism and also be set with a spring, the front end of piston rod is a ratchet.Be provided with very heavy and ball in the ratchet.

Flexible restoring organ mainly is by the slip intubate of joining with vehicle seat, is sleeved on the spring on the slip intubate, and lock pin is formed.The bottom of slip intubate offers two knock holees at least, and lock pin is installed on the vehicle frame rear portion by the mode that is threaded and is used to install in the screw that processes on the cover tube wall of slip intubate.

Because bicycle of the present utility model has increased by a cover gravity driving device again on the basis of traditional foot-operated drive system, two cover actuating devices are also deposited, and are used alternatingly.Thereby overcome the not enough and limitation that existing bicycle only has a kind of manpower foot drive device.Realized the leg muscle group is moved, and also can make waist and upper limbs obtain the purpose of sufficient movement.

The drawing of accompanying drawing is described as follows:

Fig. 1: front view of the present utility model.

Fig. 2: the cutaway view of Hydraulic Pump.

Fig. 3: the cutaway view that pushes away gear mechanism.

Fig. 4: the front view of flexible restoring organ.

Fig. 5: figure cuts open in A-A office.

Fig. 1 can be as the specification digest accompanying drawing.

The utility model is done with detailed description below with reference to embodiment (accompanying drawing): as shown in Figure 1, it mainly comprises bicycle rack bicycle of the present utility model, front and rear wheel, handlebar, vehicle seat, and parts such as foot-operated driving system form, on bicycle, also be equipped with a cover by Hydraulic Pump 1, pressure lever 2, push away the gravity driving device that gear mechanism 5, ratchet 4 and flexible restoring organ are formed; One end of pressure lever 2 is hinged on the front portion of vehicle frame, and the other end combines by the flexible restoring organ under bearing pin and the vehicle seat; The upper end and the pressure lever 2 of the piston rod 6 of Hydraulic Pump 1 are hinged, and the inner chamber of Hydraulic Pump is by hydraulic tubing and the intracavity inter-connection that pushes away gear mechanism; Push away gear mechanism 5 and be installed in the left side of cycle frame rear lower chain stay; Ratchet 4 is installed in the left side of rear wheel hub, is provided with very heavy in the ratchet and ball, and its rotating manner is identical with bicycle freewheel.

As shown in Figure 2, lay a spring in the cavity of Hydraulic Pump 1; Push away as shown in Figure 3 on the piston rod of gear mechanism 5 and also be set with a spring, the front end of piston rod is a ratchet.Above-mentioned two springs all are provided with in order to help gravity driving device to reset.

As Fig. 4, shown in Figure 5, flexible restoring organ mainly is by the slip intubate 3 of joining with vehicle seat, is sleeved on the spring 8 on the slip intubate, and lock pin 10 is formed.The bottom of slip intubate 3 offers three knock holees, and lock pin 10 is installed on the vehicle frame rear portion by the mode that is threaded and is used to install in the screw that processes on sleeve pipe 9 tube walls of slip intubate 3; The top of slip intubate 3 combines by bearing pin and pressure lever 2.

Two cover actuating devices of the utility model bicycle can be used alternatingly.When utilizing the human body self action of gravity in vehicle seat, drive pressure lever the pressure fulcrum is moved down, drive liquid presses piston pole and produce hydraulic coupling, under the liquid conductive effect, push away the piston rod displacement in the gear mechanism, thereby promote to be positioned at the ratchet on the bicycle rear wheel hub, drive wheels is rotated; Then, the human body self chin-up makes buttocks leave vehicle seat, and vehicle seat rises to original position under the effect of flexible restoring organ, finishes a circulation.According to this principle, under the conscious uninterrupted effect of human body self gravity, quiver up and down, do manual work continuously, when driving cycle racing, reach the purpose that human upper limb and waist are moved.

When utilizing gravity driving device driving bicycle to feel fatigue, can utilize the lock pin on the flexible restoring organ that vehicle seat is fixed on the appropriate location, use traditional foot-operated type of drive again instead and ride.Drive bicycle so incessantly, just can reach the purpose of whole body exercise.
