Electric collapsible bicycles

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a folding type electric bicycle, and more particularly, to a folding type electric bicycle in which an electric bicycle is automatically folded in a circular shape when a transformer button is pressed in a state of holding a knob in a one-

Generally, a bicycle is a structure in which two wheels are used, and a pedal and a chain and a gear connected to the bicycle are driven to be driven by a pedal pressing force.

A bicycle driven by such attraction forces two wheels on the body frame and chains the pedal and wheel to drive the rear wheels. It is also common to install multiple gears for the convenience of traveling. Therefore, the driver rides on the bicycle, steps on the pedal to drive the rear wheel, and simultaneously steers the steering wheel connected to the front wheel.

As bicycles do not emit carbon dioxide at all, they are an environmentally friendly means of transportation as well as contributing to public health, and it is well known that the use of bicycles is encouraged in the country. Of course, encouraging the use of bicycles is an environmentally friendly means of transportation rather than a promotion of public health.

In modern times, many kinds of bicycles are being released for leisure or special purposes rather than simple bicycles. These are the cycle of speeding up the pavement and the well-known mountain bike. Therefore, national and local governments are also making efforts to build bicycle lanes to encourage the use of bicycles.

Bicycles are often used as leisure activities, but they are more often used as a means of short-distance transportation. When used as a means of transportation, it is not a problem for young people with strong muscles, but it can be a problem for people with weak muscles. Also, there is a problem that even if the user moves a long distance to travel by bicycle, it is accompanied by a crowd.

To supplement such driving force, electric bicycles equipped with electric batteries and motors are commercially available. Electric bicycles have a problem in that the weight of the electric bicycle is considerably increased because the bicycle is literally installed only with the battery and the motor. However, it is an excellent alternative to the physical arrangement because electric energy is supplemented and operated. Of course, these electric bikes can not be carried by the user after driving in the downtown area.

Bicycles can be divided into ordinary bicycles and folding bicycles depending on whether the body can be deformed or not. In general, a bicycle can only control the height of a handle or a saddle, and a folding bicycle is a folding bicycle in which a body frame is generally folded in half, and is folded in half so that it is most often carried in a trunk of a vehicle.

In addition to folding in half, folding bikes have folding bikes called so-called strides, and there are also other low-weight folding bikes that can be folded in a variety of ingenious ways.

However, bicycles that can be driven by electric batteries and folded are almost nonexistent at present.

1, a folding type electric bicycle 1 according to a preferred embodiment of the present invention includes a front wheel 10, a wheel case frame 20, a front body frame 70, a rear body frame 90, And a saddle frame (100).

The front wheel 10 is driven by an electric battery 20 and is driven by a power source of a driving battery 20 connected to a traveling motor 30 provided inside the wheel case frame 20. [

The wheel case frame 20 covers a part of the front wheel 10 and supports the front wheel 10 rotatably.

A plurality of rollers 12 are rotatably mounted on the wheel case frame 20, and the rollers 12 are installed so as to be inscribed on the front wheel 10.

The internal gear 12a is provided on the inner side surface of the front wheel 10 and the pinion gear 31 is engaged with the internal gear 12a. The pinion gear 31 is installed inside the wheel case frame 20 And is rotationally driven by the traveling motor (30).

The front body frame 70 is rotatably installed on the wheel case frame 20 so as to steer the wheel case frame 20.

A steering post 80 is mounted on the front body frame 70 so as to be able to rotate by rotating the wheel case frame 20 and is rotatably installed to be foldable with respect to the front body frame 70.

A handle 86 is provided on both sides near the upper end of the steering post 80 and an end of the handle 86 is rotated downward so as to be folded in parallel with the handle post 80.

The rear body frame 90 is rotatably installed to be foldable with respect to the front body frame 70, and a rear wheel 91 is installed at one end thereof. The rear wheel 91 is an idle wheel to which no load is applied.

The saddle frame 100 is rotatably installed so as to be foldable with respect to the front body frame 70 and is seated in the seating groove 92a of the rear body frame 90 when folded to have a slot handle 100a .

12, a saddle 104 is installed at an upper portion of the saddle frame 100, and the saddle 104 is installed so that two panels can be folded downward.

A transformer button 105 is provided at one side of the slot handle 100a and is installed at a rotating portion of each of the rear body frame 90 and the saddle frame 100 according to the input of the transform button 105. [ The front body frame 70 is folded or unfolded by the operation of the transformer motor 75.

In addition, a trans-form battery 60 for supplying electricity to a motor other than the driving battery 50 for driving the front wheel 10 is further provided in the wheel case frame 20.

The folding electric bicycle 1 according to the present invention has a shape in which the diameter of the front wheel 10 at the front is much larger than that of the rear wheel 91 at the rear.

Referring to Fig. 1, the front wheel 10 is driven by the driving battery 50, in which the front wheel 10 is driven by the electric battery 50, in the driving of the electric bicycle 1. The traveling battery 50 is fixed inside the wheel case frame 20 and supplies power to the traveling motor 30. [

1, the traveling motor 30 drives the pinion gear 31 in accordance with the power source of the traveling battery 50 and the internal gear 12a engaged with the pinion gear 31 is eventually driven to rotate the tire 11, The electric bicycle 1 is driven by the frictional force with the floor surface.

A transformable battery 60 is fixedly installed in the vicinity of the traveling battery 50 in the same manner. The transformable battery 60 is responsible for power supply for purposes other than driving force for driving. That is, the driving force for folding or unfolding the electric bicycle 1, and the illumination such as the LED. Therefore, the electric bicycle 1 can be folded even when the power of the running battery 60 is almost consumed.

That is, according to the present invention, even if the main power source is exhausted by turning the power source on, the auxiliary power source can fold the electric bicycle 1 to prevent the electric bicycle 1 from being completely unavailable, The power of the transformable battery 60 can be regulated by the controller 40 so that it can be supplied as a driving force.

A plurality of rollers 12 are installed inside the front wheel 10 and the rollers 12 are rotatably supported by the wheel case frame 20. According to this structure, the front wheel 10 is installed to be rotatably driveable on the wheel case frame 20.

The wheel case frame 20 is connected to the steering post 80 through a steering rotation shaft 72. Therefore, when the steering post 80 is rotated, it is steered.

The wheel case frame 20 is connected to the front body frame 70 by a bearing 71. Accordingly, the front wheel 10 is rotated about the body frames 70 and 90 to be able to steer.

Since the front body frame 70 supports the front wheel 10 at a lower portion thereof, it is possible to transmit a person and its own weight to the front wheel 10 and the rear wheel 91 together with the rear body frame 90 .

The steering post 80 is installed on the front body frame 70. The steering post 80 supports the handle 86 and transmits a rotation corresponding to the steering of the handle 86 to the lower wheel case frame 20.

A pinion 73 is attached to the front body frame 70 and a driving gear 82 engaged with the pinion 73 and a motor 81 driving the pinion 73 are installed on the steering post 80, Can be folded with respect to the front body frame (70).

A pin and sensor 74 is provided on the front body frame 70. The electric bicycle 1 is fixed by aligning the steering wheel center before the bicycle 1 is folded in the form of a round dish, . That is, each frame begins to be folded only when the center is aligned by the pin-and-pin sensor 74.

An LED lamp 83 is installed at the front of the steering post 80 so as to illuminate the front when driving at night and gears 85 and a motor 84 for folding the handle 86 are installed at the upper end . The gears 85 and the motor 84 for folding the handle 86 may be folded manually and omitted for the sake of simplicity of weight and mechanical design.

A throttle-type brake is provided on the handle 86, and the throttle is wound to remove the brake lever. In addition, a speed adjusting throttle is applied so that the throttle can be wound to adjust the speed. In addition, referring to FIG. 3, the display is made through the LCD panel 80b displaying the mileage and remaining battery power, and various settings of the electric bicycle 1 can be inputted by the touch function.

The handle post 80 is formed with a cut-out surface 80a, and the handle 86 is folded and positioned there, so that the appearance of the handle post is very beautiful.

The rear body frame 90 is folded with respect to the front body frame 70 by the driving of the central folding motor 75 and the driving gear 76 and the pinion 92. Of course, the motor 75 is driven in the opposite direction.

At the same time, the saddle frame 100 is also folded by the gear 101 engaged with the gears 93, 103 formed on the pinion 92 and the rotation transmission shaft 102, 90, respectively. Although it is solved by mechanically installing the saddle 104 to be folded, it is also desirable that the saddle folding can be manually performed due to design and design problems.

When the saddle frame 100 and the saddle 104 are folded in the rear body frame 90, the outer surface of the saddle frame 100 is designed to have a circular plate shape.

Referring to Figs. 2 and 3, the bicycle 1 is shown in a state in which it can normally travel. As shown in the figure, a footrest 20b is provided instead of a pedal, and the footrest 20b is manually folded into the groove 20a and can be opened. Of course, it is possible to do it automatically.

The electric bicycle (1) has a very simple and sophisticated design because it does not show ordinary bicycle, pedal and chain.

Referring to FIGS. 4 to 7, when the transformable button 105 is pressed while holding the slot knob 100a, folding starts in a state in which the vehicle can travel.

The handle 86 and the steering post 80 are folded toward the upper surface of the front body frame 70 and the rear body frame 90 and the saddle frame 100 simultaneously rotate toward the front wheel 10 to be folded, 6 and Fig. 7.

When the electric bicycle 1 is folded, it is not a completely circular but almost circular dish shape, and it becomes easy to carry or pack, and the knob 100a can be gripped and moved. Of course, the movement is very natural and convenient because there is no element that is caught in the human body like a bag when moving.

Referring to Fig. 12, it is shown that the saddle 104 is folded. Of course, the saddle 104 can be folded into two panels, which can be manually folded or automatically installed as described above.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
