Description

The present invention relates to the technical field of a bicycle warning light, and is a vehicle light sensing flash warning device that controls to emit a warning flash corresponding to an approaching speed of a traveling vehicle and keeps a safe distance for the driver of the traveling vehicle. With respect to the invention.

Bicycles are provided with warning lights to warn the traveling vehicle in front of and behind the vehicle body or on the peripheral side to ensure the safety of driving at night, and the conventional warning light control is roughly one artificial control switch by design, and the bicycle The rider controls the vehicle lights to form different modes such as full on, half on, flash and off. However, the use of artificial control by cyclists in this way is that if the cyclist forgets to turn it on, the warning light makes no sense and in contrast exposes himself to a dangerous driving environment. .. In addition, the rider's own operation not only causes inconvenience in use, but also tends to distract when riding and increases the risk of running. Also, current traffic is becoming more and more complex, and bicycles are relatively vulnerable in complex traffic environments due to their slow speeds, and warning lights must be able to provide more clear information. For example, it may be buried in a complicated vehicle environment. Recently, related companies have developed improved structures for the defects of the conventional bicycle warning light.

Taiwan Announcement No. 514059 "Improved Bicycle Warning Light Structure" consists, in particular, photoresists, vibration switches and other electronic components, as its structure is described in the abstract, and rides a bicycle in dark surroundings. At that time, a flash action is generated in the light-emitting diode (LED) to promptly pay attention to a distant vehicle and improve the safety of riding a bicycle. Also, when the surroundings are bright, when the internal memory is adjusted and the time when the bicycle does not start exceeds the memory set time (2 to 3 minutes), the warning light front set is turned off so that the flash action does not occur. , It is not necessary to switch the switch every time the entire use is performed, and a user-friendly usage effect is achieved.

In addition, the "solar energy bicycle warning light" of Taiwan Announcement No. M274303 is composed of a shell, a circuit board and a connection socket so that its structure is described in the abstract, and the solar is on the front lid of the shell. A panel is provided to absorb the light energy of sunlight, and an electric energy is stored in the battery by a circuit board installed on the connection socket, and the battery is placed in the battery socket on one side of the connection socket and can be activated. The rear lid is convenient for replacement. When the bicycle runs in an environment where the light source is scarce, the CPU installed on the circuit board turns on the light emitting diode by the battery discharge process by the signal of the photoresist and the vibration switch, but the surroundings become bright or the vehicle is stationary. After a lapse of time, the warning light will automatically turn off, further adapting the warning light to user-friendly requirements.

However, in the above two known patent-priority structures, the light emitting diode (warning light) causes a flash action when the surroundings become dark and the vehicle rides on a bicycle due to the photoresist and the vibration (vibration) switch. Although it is possible to warn the traveling vehicle, the vibration switch of the known patent prior application can only control the generation of a simple warning flash on the light emitting diode (warning light), and the warning flash of the public patent prior application is , It has not changed in response to the difference in the relative approach speed of the traveling vehicle, and the driver of the traveling vehicle approaching the peripheral side cannot be made to judge the vehicle speed by the warning flash, and the current traffic is relatively complicated. In the environment, the driver of a traveling vehicle is still liable to pose a risk of misjudging the approaching speed of the vehicle, which is the biggest defect.

Therefore, the warning flash emitted by the structure of the above-mentioned prior application cannot make the driver of the traveling vehicle approaching the peripheral side of the bicycle evaluate and judge the approaching speeds of both vehicles, and there is a drawback that a misjudgment causes danger. How to improve it is an issue that the present application wants to solve.

The magnitude of the brightness sensed by 71 is received.

The pulse modulation unit 40 (Pulse Width Modulation, PWM is a technique for converting an analog signal into a pulse wave. Generally, the period of the pulse wave after conversion is fixed, but the duty ratio of the pulse wave is that of the analog signal. It changes depending on the size, changes the brightness of the light emitting unit 12, and the voltage / current is completely turned on (ON) or completely off (OFF) by repeatedly loading the pulse sequence into the analog load in an open / close manner. 1 (with power, light emission in FIG. 1) and 0 (no power, light emission in FIG. 3) are power supply modes) are electrically connected to the condensing unit 30 and the light emitting unit 12, and the pulse modulation unit 40 is connected to the pulse modulation unit 40.

As shown in, the vehicle light 10 maintains a normal display (simple lighting) when not approaching, and when approaching, the speed sensor 20 further senses the approaching speed of the traveling vehicle 70. When the approaching speed is high, the main controller 50 outputs a control signal to the pulse modulation unit 40, and the pulse modulation unit 40 adjusts the light emitting unit 12 to a fast flash state. If the approaching speed is slow, the main controller 50 outputs a control signal to the pulse modulation unit 40 and adjusts the light emitting unit 12 to the pulse modulation unit 40 to a slow flash state.

When the brightness of the vehicle light is high, the main controller 50 outputs a control signal to the pulse modulation unit 40, and causes the pulse modulation unit 40 to adjust the light emitting unit 12 to a fast flash state. When the brightness of the vehicle light is low, the main controller 50 outputs a control signal to the pulse modulation unit 40, and causes the pulse modulation unit 40 to adjust the light emitting unit 12 to a slow flash state. Finally, the condensing unit 30 senses whether the traveling vehicle 70 has disappeared (disengaged), and if it has disappeared, the main controller 50 maintains a normal display (simple lighting) on the vehicle light 10. If it disappears, the main controller 50 keeps sensing the brightness of the headlight 71 of the traveling vehicle 70 by the condensing unit 30, and controls the light emitting unit 12 to perform a fast flash and a slow flash. ..

Satisfy the detection and judgment. When the main controller 50 simultaneously receives the approaching speed of the traveling vehicle and the brightness of the headlight of the condensing unit 30 sensed by the speed sensor 20, the speed sensor 20 and the condensing unit 30 are doubled.
