Description

Front wheel drive motor bicycle {A FRONT-WHEEL DRIVE BICYCLE}

The present invention relates to a front-wheel drive motor bicycle, and more specifically, a fixed portion installed on the upper part of the rear wheel, a rim portion provided with a drive motor to the front fork, and the rotational speed of the drive motor It consists of a speed control unit for controlling, and a power box for supplying and controlling power to the rim and the speed control unit, and usually pedals the bicycle, and when driving on a hill or a long distance, it is easy to reach a desired destination by driving power of a driving motor. The present invention relates to a front-wheel drive motor bicycle that can be moved and is easy to install on a conventional bicycle.

In general, bicycles are designed to be convenient to move between points and points, the recent increase in the number of vehicles, the problem of traffic and environmental pollution is getting serious day by day, due to the lack of exercise caused by various diseases of modern people Its use is changing and its range of use is increasing as an exercise equipment for health and as a transportation aid for using public transportation.

Such a bicycle basically has two front and rear wheels, a frame supporting the front and rear wheels, a saddle installed at the center of the frame and seating the driver's hips, and steering in front of the saddle. The power transmission structure is composed of a front sprocket on which a pedal is fixed, and a rear sprocket connected to the front sprocket through a chain and installed on a rear wheel, and is rearwarded by the pedal rotational force of the front sprocket. As the side sprocket rotates, the power transmission and the position movement of the bicycle are made.

Although such a bicycle is a very useful means of transportation that provides modern people with limited leisure time with easy access to exercise and can suppress traffic congestion by suppressing their use of cars, they can also reduce environmental pollution. It had a fundamental limitation that its scope of use could not be expanded.

That is, a bicycle can move in a short time while consuming less stamina than a user running at the same distance, but in Korea, where there are many mountainous topography, hills have a lot of terrain, and in some cases, riding a bicycle is more than walking or running. On the contrary, if a person needs more physical strength, and if the distance to the destination is far, too much physical strength has to be consumed.

In order to solve this problem, the motorcycle driving method is used, but the motorcycle driving method is difficult to purchase and use by consumers because of the noise, heavy weight, and expensive price, and also because it uses oil such as gasoline. There was a problem that could be caused.

The purpose of the present invention to improve this is to be able to simply attach and detach the present invention to a conventional bicycle, such as a conventional non-folding bicycle or folding bicycle, so that the existing bicycle can also be wheeled by the drive motor.

In addition, the present invention is a front wheel drive motor bike that allows the bicycle to be wheeled by the force of the rear wheel connected to the chain and the pedal, and the driving motor installed on the front wheel to make the driving easier in the place where it is difficult to travel like a hill. To provide.

Referring to the operation of the present invention made of such a configuration as follows.

First, after removing the front wheel of the bicycle and the tire and the tube is separated and fixed to the tire and the tube to the wheel frame to which the drive motor is attached, the rim portion is fixed to the front fork as nuts, bolts, washers.

Subsequently, after removing the handle of one side handle and inserting the speed adjusting part, the catching part is installed on the upper part of the rear wheel. At this time, the inner receiving plate of the catching part is mounted and fixed as a fastener, Fix the connecting frame and the fixing frame to the connecting shaft of the rear wheel and the connecting rod as bolts and nuts.

In addition, the power box mounted in the seating space of the take-up part to supply power to the rim and the speed control unit and insert the power line and the speed control plug of the speed control unit into the connection jacks formed on one side of the power box, respectively. Connect.

In order to drive the bike, the key is inserted into the power cutout on the side of the main body and turned clockwise, the indicator light turns green and the bicycle is ready for operation. Turning the speed control on the right side increases the speed and makes the bike run.

On the other hand, to remove the power box from itself, unplug the power key from the power box, disconnect the power line and speed control plug from the rim connected to the power box, and then release the fastener from the power box and remove the power box from the power box. Disconnect.

When charging the charging battery in the power box, the charger plug is inserted into the power connector of the power box and plugged into an AC 220V power outlet to charge the battery until the charging indicator turns from red to green.

As described above, in the present invention, unlike a motorcycle which is driven only by a driving motor, the main driving is a manpower, and the driving by a driving motor adds the manpower and the motor driving force. As a driving force, it can be used selectively.

Therefore, even if you normally drive the bicycle with the help of a manpower using pedals and chains or pedals, gears, and rotary shafts, you can selectively drive the rim drive motor to the destination when driving on hills or over long distances. There is an advantage to ensure safe driving.

In addition, the present invention uses a pollution-free, no-noise electric energy to drive the motor, so there is no problem of noise or environmental pollution, and because the electric energy is cheaper than gasoline or diesel, the maintenance cost is low, It is useful to be able to use both manual operation and automatic operation by motor drive using electric energy.

Although the present invention has been shown and described with respect to specific embodiments, it has been found that the present invention can be variously modified and changed without departing from the spirit or the field of the present invention provided by the following Utility Model Registration Claims. I want to.

As such, according to the present invention, the present invention can be easily attached and detached to a general bicycle such as an existing non-folding bicycle or a folding bicycle. There is an excellent effect to expand the choice of bike that can be wheeled by.

In addition, the present invention has the advantage that the bicycle is wheeled by the manpower by the rear wheel connected to the pedal and chain connected to the usual, and in the place difficult to run by the hill or manpower, the driving motor installed on the front wheel makes the driving easier. .
