Abstract

PURPOSE:To immediately give information of the occurrence of an accident, to the outside, by providing a vehicle with an accident indicating lamp so that the lamp is lighted by the cutoff of an optical fiber caused by a shock which acts to a buffer when the vehicle collides. CONSTITUTION:When an amplifier 17 is put in operation as a result of closure of a switch 21 caused by turning on an ignition key, an optical signal is continuously applied from a light emitter 15 to a photodiode 16 through an optical fiber 13 so that a relay coil 18 is energized through the amplifier. For that reason, an accident operating switch 25 is opened so that an accident indicating lamp 30 is off. When a collision accident has occurred to a vehicle to give a shock to a buffer 12 to cut off the optical fiber 13, the optical signal is blocked from the photodiode 16 so that the drive of the amplifier 17 is stopped. As a result, the relay coil 18 is deenergized to close the switch 25 to light the accident indicating lamp 30.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a vehicle accident display which, when a vehicle collision 1 occurs, turns on the LJL failure indicator light provided on the vehicle body number to notify the outside of the occurrence of the accident. equipment (double one).

If an accident occurs while the vehicle is running (double i4 gN), the body of the vehicle (-
When it is easy to confirm from the outside, the driver of the two Oki vehicles, the driver of the surrounding Oki vehicle, the cow, and the two following Oki vehicles are traced by rolling stones. The occurrence of ¥q1 error +
It is essential to prevent the occurrence of double collision @1 because 4H<1.

Conventionally, this purpose (- when a vehicle collides with
(Two raindrop acceleration detectors are installed on the vehicle to detect force as iP and ultimate acceleration, and this detection output is converted into a mechanical (No. 3 or electrical signal), and this converted signal is used to detect A system has been proposed in which an oil body (HQ indicator) lights up to notify the occurrence of an accident.

However, in the proposed method, the detection sensitivity of the detection nail 1 that detects the impact acceleration is only partial.
If a large number of [1;τ intelligence toys 1] are not installed on the vehicle panel, the detection area will be limited, and the installation location (:Therefore, the vibration energy may be lost during the process and cannot be detected. Therefore, it is necessary to select the installation position V1° when installing the equipment on the two vehicles. 'i It is necessary to prevent the accident indicator light from lighting up (-, which complicates Tsuzo's work,
For the first few words, a very precise J1M adjustment is required.

Furthermore, in the case of a system that operates using two electrical signals, it is necessary to install an electrical signal transmission line inside the vehicle, and there is a risk that external sound signals may enter this transmission line and cause malfunction.

This invention is based on the above-mentioned conventionally proposed system.
In addition to reducing the size of the entire concentric core and reducing the space it occupies, we also need to improve its manufacturing and assembly (one special method, one
To provide a skewer fault indicator for a vehicle that does not require maintenance work and can sensitively detect the occurrence of a collision and turn on an accident indicator light.

In the vehicle damage display device [N] of the present invention, an optical fiber is arranged along the curved surface of the shock absorber of the vehicle. A light emitting body that supplies light is optically connected to the other end of the fiber. A control means is provided for detecting interruption of the optical signal and turning on an accident indicator light provided on the vehicle 2').

Below, the vehicle up failure indicator of this invention, f, j, will be explained in its first embodiment using Ill +fi+.
