Abstract

The present invention relates to an electric bicycle made by applying a structure of a bicycle and a worm gear method of an outboard engine. A bicycle is not merely meant for health, leisure, and traffic issues but is being considered as an alternative to the impending energy crisis. In particular, an electric bicycle without limitation, which is caused by the wind, uphill, long distance and so on and imposed to a common bicycle, is expected to be an eco-friendly transportation means in the future. The worm gear and a DC motor are used instead of a chain. The electric bicycle is easy to manufacture. The speed of the electric bicycle is controlled by using a speed controller installed on a handle thereof. A brake structure of the electric bicycle is the same as a brake structure of a common bicycle. Pedals do not move and only the motor and the worm gear rotate, as if a bottle cap is loosened, even when a user steps on the pedals when the motor rotates as the pedal having a motor shaft with a male screw thread and a female screw thread is used by applying a structure for fastening and loosening a bottle cap. The electric bicycle is driven by driving the worm gear with human power since the pedals are completely twisted around the motor shaft in the same way that a bottle cap is twisted to close a bottle when the motor is stopped and a user rides the electric bicycle with human power.

Description

Electric bike {electric bike}

The history of bicycles is long and there are many kinds of electric bicycles, but most of them have been developed with technology using chains.

The present invention uses a worm gear and a dc motor instead of a chain, and the speed is controlled by using a speed regulator attached to the handle of the bicycle, and the brake structure is the same as that of the bicycle.

The pedal part uses a pedal which is made of a male thread and a female thread in a motor shaper by applying a structure that winds and uncovers a bottle cap. Even if a person steps on a pedal like a bottle cap unrolled when the motor rotates, only the motor and the worm gear rotate, The pedal does not move.

When the motor is stopped and the bike is run by manpower, the pedal is completely wrapped around the motor shaper in such a way that it closes the cap and winds the worm gear with manpower to run the bicycle.

It is made by applying the structure of the bicycle and the worm gear method of the outboard engine.

Bicycles are considered to be an alternative to the energy crisis, not just for health, leisure, and transportation.

Electric bicycles, especially those that are not subject to regular bikes such as wind, uphill, and long distance, are expected to become eco-friendly vehicles for the future.

Bicycles as well as electric bikes have not been able to escape from the way of using chains for many years, and there are presently bike and electric bikes that need to be reinstalled when the chain is peeled off.

It uses worm gears and dc motors instead of chains. It is easy to make and adjusts the speed by using a speed controller on the handle of the bicycle. The brake structure is the same as the bicycle.

Electric bicycles using worm gears will be used as a high-performance, eco-friendly product that replaces heavy motorcycles and passenger cars with light weight and fast speed.

FIG. 1 shows a worm wheel structure that connects a worm gear attached to a motor to a worm gear attached to a rear wheel, and a pedal portion that employs a structure in which a screw cap is closed and closed to provide a motor shaft with a male thread and a female thread. Even if the person steps on the pedal as if the cap is unrolled, only the motor and the worm gear rotate, and the pedal does not move.
When the motor is stopped and the bike is run by manpower, the pedal is completely wrapped around the motor shaper in such a way that it closes the cap and winds the worm gear with manpower to run the bicycle.
2 is a view showing a worm gear fixed to a chain stay portion of a bicycle as a whole.

1, a worm gear 106-1 is fixed to a right shaper of a dc motor 106, and a male thread 110 is formed by unwinding and loosening a pedal on an outer shaper of the dancer 106, and a pedal 109 having a female- After attaching to the motor shaper, fit the stopper to the motor shaper to secure the pedal.

The battery 108 is fixed to the bicycle top tube and the speed regulator 107 is attached to the bicycle handle.

the worm wheel 101 and the bearing 103 are brought into contact with the lower side of the dc motor worm gear so that the worm wheel shaper 102-1 enters the worm wheel sharp start pipe 102 and the worm gear 112 is mounted on the center axis of the rear wheel The rear wheel worm wheel 105 and the bearing 104 are attached to the worm wheel sharp start pipe 102 and the teeth of the worm wheel 112 and the rear wheel worm wheel 105 are fitted to the center shaft of the rear wheel, The worm wheel sharpening pipe 102 is fixedly attached.

2 shows a state in which the worm gear 112 and the rear wheel worm wheel 105 are engaged with the teeth of the worm wheel 112 and the chain stay 113 on the center axis of the rear wheel and the worm gears 106-1 and 106-1 of the dc motor The whole of the structure in which the teeth of the worm wheel 101 are engaged, the battery 108 is attached to the tower tube, and the speed regulator 107 is increased in speed when the handle is turned.

Claims

Bicycle power structure using worm gear and worm wheel and overall structure for bicycle

Using a pedal with a male thread and a female thread on the motor shaft, the motor is rotated and the worm gear only rotates, even if the person is pressing the pedal, When the bike is run by manpower, the pedal is completely wrapped around the motor shaper in such a way that it closes and closes the bottle cap, and the worm gear is driven by the manpower to run the bicycle
