Abstract

When riding a bicycle, the only ways to make right turns, left turns, or U-turns to alert people and vehicles around you are to ring the bell attached to the bicycle or raise and lower your arm to indicate the direction you are going, which results in dangerous one-handed riding. When considering whether there was a better way, a problem arose. [Solution] The bicycle in this invention is equipped with turn signals in vermilion or other colors such as blue, red, and inverted colors, similar to those on motorcycles, and an electronic sound-emitting transmitter as an alternative to the bell currently attached to bicycles.

Description

Technical Field

[0001] The invention of the present application is equipped with a switch that is powered by a battery attached to an electric bicycle invented and developed in recent years. When the switch is turned on, it makes a clicking sound, and on the right side, a light blue light is turned on, and on the left side, a winker that flashes a light named a rejection color of red or pink is invented. In addition, when the switch equipped with a power source from the battery of the electric bicycle is turned on, when the electric bicycle is running, a technical ability is generated to emit an electronic sound to notify people and obstacles in front of the danger.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When riding a bicycle and turning right, left, or making a U-turn, etc., in order to notify people and vehicles around, the only way is to ring the bell equipped on the bicycle or raise and lower the arm to indicate the direction of travel, resulting in one-handed driving, which is dangerous. When thinking about what can be done, a problem occurred. Means for Solving the Problem

[0005] On the bicycle invented in the present application, like a motorcycle, although the colors are different, a transmitter that emits an electronic sound is attached to it as a direction indicator that becomes blue, red, or the reverse color and a bell currently attached to the bicycle. Effects of the Invention

[0006] By attaching turn signals to the bicycle developed in this invention, it becomes possible to ride with one hand, without taking your hands off the handlebars, and without having to use hand signals. When there are people or obstacles in the direction of travel, ringing the bell attached to a conventional bicycle was easily perceived as "get out of the way, you're in the way," but in this invention, the bell is eliminated and instead a device that draws power from the battery attached to the bicycle is installed to play electronic sounds or electronic melodies. When this is switched on and sounds, it becomes gentler and can inform people and obstacles ahead that a bicycle is coming from behind. [Brief explanation of the drawing]

[0007] [Figure 1] The illustration shows a bicycle equipped with a battery-powered electric motor, a technology invented and developed in recent years. By switching the switch on and off, an electronic sound is emitted, and the turn signal on the right side of the frame flashes with a light blue light, while the turn signal on the left side flashes with a red or pink light. Modes for carrying out the invention

[0008] Currently, the law stipulates that ships and aircraft must be equipped with blue flashing lights on the starboard side and red flashing lights on the port side when in navigation. This is to make the direction of travel of such moving objects immediately apparent. Applying this principle, the electric motorized bicycle in this invention is equipped with a light blue turn signal on the right side in the direction of travel, and a vermilion or pink turn signal on the left side. [Examples]

[0009] The turn signals attached to the electric-powered bicycle according to the present invention, when the switch is turned on, a light blue flashing light on the right side flashes with a clicking sound, and when the switch on the left side is turned on, a vermilion or pink flashing light illuminates. Because of the distinctive colors, when surrounding vehicles or people see them, the direction of travel of the electric-powered bicycle according to the present invention can be immediately understood at a glance. Potential for industrial use

[0010] In recent times, with the sharp increase in traffic accidents involving cyclists, and with wearing helmets becoming a recommended practice, bicycle manufacturers are increasingly competing to improve safety while cycling. Therefore, introducing the invention described in this application to the industrial sector would have extremely high potential for industrial use. [Explanation of symbols]

Claims

1. Recently invented and developed electric bicycles draw power from a battery, and when a switch is added to it, the lights and turn signals on electric bicycles, like the lights and turn signals on motorcycles, will flash with a clicking sound, and the right side will have a vermilion or light blue light, while the left side will have a vermilion or pink light, which are referred to as "rejection colors."

2. This is a warning electronic sound output device that draws power from a battery attached to an electric bicycle, which has been invented and developed in recent years. By attaching a switch to it, when the switch is used for input or output while riding, an electronic melody is emitted to warn people or obstacles ahead of danger.
