用できる技術を提供するものです。[Industrial field of application] The present invention makes it difficult for a person driving a car to see a person who commutes to school, commute to school, or attend a school by bicycle at night. Even more so on rainy nights. This is to reduce contact accidents due to such difficulty in viewing as much as possible, and to ensure that safety by automatically displaying with a light that flashes when the vehicle is running midway. While the bicycle is parked, the vibration sensor detects a slight vibration of the bicycle and activates the theft alarm buzzer to give an alarm. We provide technology that can be used inexpensively and easily for warning of such personal safety and theft accidents of motorcycles, especially bicycles.

Description of the Related Art In the prior art, there was only a method of informing the existence of a vehicle by shining the light of the automobile on the cover of the rear wheel of a motorcycle, particularly a bicycle, and reflecting the light of the shining light. Therefore, it may or may not be reflected depending on the angle of the incoming light, so that it does not necessarily indicate the existence. Moreover, because the driver of the car could be delayed for a moment to determine whether the vehicle is parked or running, it was easy to lead to an accident. On the other hand, although the theft alarm device for motorcycles, especially bicycles, was a single unit, theft alarm and running display, especially automatic running display,
There has never been a device that has both functions.

A vibration sensor that uses an optical sensor such as s to detect vibrations that occur while the bicycle is running, that is, a vibration sensor that detects the vibrations by opening and closing an electrical contact mechanically configured. Any vibration sensor made of semiconductor or the like may be used, but a so-called vibration sensor is used. In addition, a buzzer that sounds intermittently in the event of a theft, a switch that can set an ID code that can be stopped only by the owner, and a light emitting diode that flashes only when the bicycle is running at night are used for running display. This is a night-time traveling indicator with a two-wheeled vehicle theft alarm, which is a means of solving the problems by incorporating an electronic circuit having the above functions into a printed circuit board.

以上に述べた作用を持つものです。[Operation] At night or in a place like a dark tunnel, it is difficult for a person driving a car to find a running bicycle. This is especially true on rainy nights and when you are wearing black clothes in winter. If the bicycle is automatically driving at night or in a dark place, a flashing flashing light on the rear of the running indicator will make it easier to find and even reduce contact accidents. In addition, there are many theft accidents such as bicycles these days,
If someone other than the owner rides a bicycle while parked,
The built-in vibration sensor detects the vibration generated while riding a bicycle and makes the buzzer ring intermittently. It is necessary to match the ID code known only to the owner to stop the sound of this buzzer. That is, it has a bicycle theft alarm function. The real value of these two functions is theft when parking at night. Since the ID code is not released for the theft alarm, if a person other than the owner rides on a bicycle, the theft alarm buzzer will ring and the running indicator light will flash to make it easier to find the accident. The two-wheeled vehicle theft alarm function and traveling indicator of the present invention have the above-described actions.

ます。[Embodiment] An example of the embodiment is shown in Fig. 1 and its structure is shown in Fig. 2. In Fig. 1, A is made of red transparent plastic whose inside is diamond cut on the running display. B is the main body, C is an attachment for attaching to the bicycle, and D is a knob for the ID code setting switch. Figure 2 explains the configuration in a little more detail. I will explain based on Figure 2. A is a display cover made of diamond-cut red transparent plastic so that the light of the traveling display light can be easily seen outside. B is the main unit where the switch for setting the ID coat is attached, F is the battery chamber, and G is the sound pressure chamber of the alarm buzzer, which has small holes for making sounds outside. The H has a chamber for inserting a printed circuit board that incorporates electronic circuits to perform its functions. A vibration sensor that detects vibrations, a light sensor that distinguishes between light and darkness, and a light-emitting diode for running display are built into the printed circuit board along with electronic components. By combining these, the two-wheeled vehicle anti-theft alarm night driving indicator shown in Fig. 1 is constructed. Figure 3 shows an example of an electronic circuit. V c is a power supply line, S is a vibration sensor that converts vibration into opening and closing of electrical contacts by a mechanical mechanism to make it inexpensive, R1 is a limiting resistor that limits the current flowing through the vibration sensor, and C1 is a vibration sensor. Capacitors that absorb spike noise generated when electrical contacts open and close, 1/6, 2/6, C2, C3, R2, R of IC-1
3 is a circuit that detects the rising edge of the pulse when the electrical contact of the vibration sensor changes from open to closed. Similarly, when closing to opening, IC-1 4/6, 5/6, 6/6, C
It is a circuit that detects the falling edge of the pulse by 4, C5, R4, R5. The reason why these two circuits are necessary for electrical detection of vibration is as follows. When the bicycle is tilted or fallen down when the bicycle is parked, the electrical contacts are closed because the vibration sensor is mechanically made.
If you wake up the bicycle quietly in this state, the circuit that detects the rising edge of the pulse will not work. Therefore, a circuit that detects the falling edge of the pulse should be provided, and two circuits are required to cover the drawbacks. Is. D1, D
It composes a 3/6 NOR circuit of 2, R6 and IC-1 and shapes the pulse generated by the vibration in the previous stage and sends the signal to the next stage. IC-2 is a retriggerable one-shot multi-vibrator (hereinafter referred to as one-shot multi), which holds its output for a certain period of time. If the vibration signal pulse is input many times within a certain period of time, it will be reset each time and hold the output for a certain set time determined by C6, R7 and C7, R8 from the final pulse signal. Since the IC-2 in this stage is an IC with two circuits, it has two outputs. One is used to output the buzzer, and the other is used to output the flashing light for running display intermittently. The output for the buzzer sounds is input to the ID code setting switches for ID1 and ID2. Stop the buzzer sound by matching the ID code with an external knob. In other words, the ID code must match when driving, and the ID code must be changed when guarding against theft. The signal output from the ID setting switch is 1/6, 6/6, D3, D4, R of IC-3.
9, R10, R11, R12, C8. With C9, it oscillates intermittently and oscillates at a frequency that matches the frequency of the buzzer sound, creating the original vibration of the buzzer. R13, R1
By 4, Q1, make a power amplifier to make the buzzer sound, and make the buzzer BZ sound. L1 is a boost coil to increase the buzzer sound. Next, the output for intermittently blinking the other flashlight of the IC-2 is
Optical sensor cds for discriminating light and dark, 1 of IC-4
/ 6, 2/6, C10, R15 and D5, D6, R16,
It is used as the input of the AND circuit composed with 3/6 and 4/6 of IC-4. If it becomes a certain darkness and there is a vibration signal of the bicycle while riding, it will be output to the oscillation circuit of the next stage. 5/6, 6/6, D7, R1 of IC-4
7, R18, C11 are oscillator circuits for intermittently flashing the flashlight during traveling, and R19, Q2, Q3 are
The power amplifier circuit. R20 is a limiting resistor that limits the current flowing through the flashlight LED. As described above, the electronic circuit is constructed at a low cost and built into the printed circuit board to form the motorcycle anti-theft alarm and traveling indicator as shown in Fig. 1.

とに多大な効果を発揮するものです。The effect of the present invention is that a bicycle running at night or in a dark place, particularly on a rainy night, is difficult for a driver of an automobile to find, so the nighttime running display is flushed. Blinking the light makes it easier to detect and can be expected to reduce the number of car accidents. Further, since the present invention has a built-in vibration sensor for detecting vibration while the bicycle is running, in the event of a bicycle theft accident while parking the bicycle, the vibration when moving the bicycle can be detected to be effective as a theft alarm. I can do it. In particular, this effect is that the buzzer that sounds when a theft accident occurs cannot be canceled by those who do not know the ID code setting. In case of theft accident at night, the effect will be further enhanced by flashing the running display flashlight together with the sound of the buzzer. In the past, there were individual units, but when using all, it was necessary to turn the power switch on and off, which was time-consuming, and the inconvenience of having to purchase and install each separately was integrated. And ID
Just set up a code setting switch and switch it,
Both have the convenience of being used automatically and easily. As a side effect, when a child, an elderly person, or a physically handicapped person walks outside at night or when jogging, he or she can attach it to the waist for a walking display, or can be attached to a baby carriage or a wheelchair for a physically handicapped person to display its presence. We can also expect to reduce car accidents. In addition to having the effect of preventing such a personal injury, it is also extremely effective in providing the technology of the present invention at low cost.
