Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to motorized bicycles, and more specifically, the present invention relates to motorized bicycles, and more specifically, Regarding a bicycle equipped with a drive electric motor.

0002

[Conventional technology]

As is well known, bicycles are often used for commuting over relatively short distances. Among the bicycles is a motorized bicycle with a motor attached.

0003 By the way, conventional motorized bicycles have engines that use liquid fuel. Engines, carburetors, fuel storage tanks, etc. were attached to the bicycle.

0004

[Problem that the idea aims to solve]

According to the above conventional technology, the prime mover is driven by consuming liquid fuel. It allows the bicycle to run.

[0005] However, fossil fuels, which are the source of liquid fuels, are finite and cannot be used. A finite amount of energy is consumed by traveling a short distance such as using a bicycle. -It would be a waste of resources.

[0006] Additionally, as the prime mover consumes liquid fuel, it generates exhaust gas. Exhaust gas causes environmental pollution such as air pollution.

[0007] Therefore, as the population increases, the use of the conventional motorized bicycles mentioned above will increase. , finite energy resources are likely to be consumed, and environmental pollution is likely to increase. There was a problem.

[0008]

【the purpose】 Therefore, the purpose of this invention is to run a bicycle using a prime mover. Of course, driving the prime mover does not consume finite energy resources and reduces air pollution. It does not cause environmental pollution such as We offer a motorized bicycle that makes it easier to eliminate energy loss when converting energy into energy. It is to serve.

[0009]

[Means to solve the problem]

In order to achieve the above object, the present invention has the following technical means. That is, the example This will be explained using the reference numerals in the accompanying drawings that correspond to When rolling a bicycle, a direct drive electric current is used to directly drive the rear wheel 4 of the bicycle 2. The motive 6 supplies power from the battery 11 mounted on the bicycle 2 via the power switch 15. The direct drive electric motor 6 is configured to be The rotation speed can be adjusted in several steps by the speed change switch 18 provided on the handle 13 of 2. A brake 2 is provided on the handle 13 and is capable of changing speeds. A motorized vehicle characterized by being able to be braked by operating 0. This is bicycle 1.

0010

[Effect]

Based on the above configuration, a direct drive electric motor 6 is attached to the rear wheel 4 of the bicycle 2. It is powered by a battery 11, so it can run without using fossil fuels. It is a type that does not emit exhaust gas. And the direct driver Since the output shaft of the electric motor 6 is the axle 5 of the rear wheel 4, energy loss occurs. It becomes difficult.

[0011]

【Example】

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

0012 As shown in FIG. A motor 6 and a battery 11 are attached. The bicycle body 2 has a front wheel 3 and a rear wheel 4. , a pedal 8 and a handle 13 , and an axle-side skid provided on the axle 5 of the rear wheel 4 . It is wound between the sprocket 7 and the pedal side sprocket 9 provided on the pedal 8. When the pedal 8 is stepped on, the rear wheel 4 rotates by the chain 10, which is attached to the bicycle. Body 2 is designed to run.

[0013] FIG. 2 shows a direct drive electric motor 6. The motive device 6 is attached to the rear wheel 4, and the axle 5 of the rear wheel 4 is connected to the above-mentioned direct drive. This serves as the output shaft of the motor 6. And the axle side sprocket 7 is attached to the axle 5. installed.

[0014] Figure 3 shows the handle 13, which is equipped with switches for performing various operations. ing. A power switch 15 and a light switch 16 are provided on the left handle 14. A speed switch 18 and a buzzer switch 19 are provided on the right handle 17. Also, brakes 20 are arranged on the left and right sides. And in the center there is a voltmeter 21 are arranged.

[0015] FIG. 4 shows the battery 11, which is connected to the bicycle main body 2 as shown in FIG. It is located in the center of The side of the battery 11 is equipped with external power for charging. A second charging section 12 is arranged.

[0016] Next, a method of using this motorized bicycle 1 will be described with reference to FIG. First, the electric Turn on the power switch 15. At this time, is the voltmeter 21 displaying within a certain range? confirm. Next, press pedal 8 with your foot. Then, the bicycle 2 reaches a predetermined speed, e.g. When the speed reaches 8 km/h, the direct drive motor 6 automatically starts and the pedal Stop referring to Rule 8. When the direct drive electric motor 6 starts, the rear wheel 4 is directly driven and the bicycle 2 travels.

[0017] In addition, the direct drive motor 6 is activated by the speed switch 18 on the right handle 17. It can be changed into two gears, and can be adjusted according to road conditions, cargo, etc. Also, the left The light is turned on by the light switch 16 on the handle 14, and the right handle 17 The buzzer is sounded by the buzzer switch 19. Also, the brake It is braked by 20.

[0018] If the voltmeter 21 is lower than a certain range when the power switch 15 is turned on, charging is performed. You have to. In that case, charge the power cord from the external power source as shown in Figure 4. 12 and supplies power to the battery 11. In addition, if you want to know the voltage when charging , is displayed on the voltmeter 21 when the power switch 15 is turned on.

[0019] As mentioned above, this motorized bicycle 1 uses a direct drive electric motor as the prime mover. Since it uses a machine 6, it is not possible to use liquid fuel such as gasoline to drive the prime mover. The battery 11 is charged and used with power from an external power source without any It can run without consuming energy resources. It also emits exhaust gas It does not cause environmental pollution such as air pollution. Moreover, Daire Direct drive motor 6 is directly attached to the rear wheel 4. The power of the electric motor 6 is directly transmitted to the axle 5 of the rear wheel 4, eliminating energy loss. It is possible.

[0020] Note that in FIGS. 1 and 2, the front wheels 3 and rear wheels 4 are omitted.

[0021]

[Effect of the idea]

As detailed above, according to the invention of claim 1, limited energy resources can be used to By driving short distances, you can use direct drive power without consuming it. Since the motive device is attached directly to the rear wheel of the bicycle, there is no energy loss due to electric power. In addition, since no exhaust gas is emitted, it reduces environmental pollution such as air pollution. It has the advantage of not causing

[0022] Furthermore, according to the invention of claim 2, when traveling at low speed, the user must pedal Therefore, it is highly safe as a vehicle with a motor, and it also uses less energy. It has the advantage of no waste.
