Abstract

PURPOSE:To enable the decelerating condition of a car to be known to the following car so as to prevent a collision from behind or the like before its occurrence, by parallelly connecting a deceleration sensor to the stop lamp lighting circuit of a main brake and turning on a stop lamp even when an automobile is still under the decelerating condition. CONSTITUTION:A deceleration sensor 1 is parallelly connected to a stop lamp lighting circuit of a main brake 11, and a switch 9 of said circuit is turned on even when an automobile is under its decelerating condition. Then a stop lamp 10 is turned on by a battery 8. Here the deceleration sensor 1 operates such that when the automobile advancing in the direction A enters its decelerating condition, a weight 5 is moved in the direction A to cause a switch operating lever 7 to depress a working button 2a of a switch 2, thus the switch 2 becomes its on- condition. Then an on-off switching condition of the switch 2 is changed by adjusting tension of springs 3, 4 holding the switch operating lever 7 and a vertical movement position of the weight 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stop lamp lighting device having a deceleration sensing function, and is intended for safe driving of an automobile.

Conventionally, the reason why a stop lamp at the rear of a vehicle body is turned on is to notify the rear vehicle width in advance that the vehicle is slowing down or stopping, and to prevent a rear-end collision or the like.

The operation for this purpose in a vehicle was to turn on a stop lamp by stepping on the foot brake, which is the main brake.

For the safe driving of a car, it is of course important to transmit information to vehicles behind by turning on stop lamps before stopping, but it has been shown that transmitting information during a deceleration state similar to a stopped state is extremely important. Crabs have also been recognized in terms of sustenance.

Actual deceleration conditions include engine braking, exhaust brakes used mainly in diesel cars, trucks, buses, etc., handbrake activation, which may be applied when there is an abnormality in the main brake, and punctures. There are times when there is abnormal deceleration.

The present invention is designed to sense the deceleration state and turn on all the stop lamps through the operation of a switch or the like when the deceleration reaches a certain level even in such a state.

Hereinafter, the content of the present invention will be explained according to an embodiment. A deceleration sensor 1 (disposed in parallel with the stop lamp lighting circuit of the i7 main brake 11) that operates by detecting deceleration is installed in the stop lamp lighting circuit even during deceleration state. When the switch 9 is turned on, it is 11r'!.

The deceleration sensor 1 extends upward from the main body of the switch 2, has a table weight 5 on the upper part whose mounting position can be changed, is supported by a spring 3.4 at an appropriate position at the lower part, and is further provided with a damper 6 at an appropriate position at the lower part. The switch actuating rod 7 is configured to be able to be fanned.

The switch operating rod 7 is attached to an appropriate position on the main body of the switch 2, and is configured to be able to swing forward and backward using the attached location 7a as a fulcrum.

In this deceleration sensor, for example, if the vehicle width direction is the forward direction or the direction indicated by the arrow as shown in FIG.
The operating button 2a is pushed in to turn on the switch. The important conditions of the switch 2 can be changed by controlling the spring force of the spring 3.4 holding the switch operating rod 7 and adjusting the vertical movement of the weight 5. Therefore, even if the deceleration state is the same, the important conditions of the switch 2 can be changed arbitrarily.

By attaching the damper 6 to an appropriate location on the weight support rod 7, it can be made to function so as not to operate in the event of sudden back-and-forth movement such as knocking that is not directly related to safe driving.

This deceleration sensor], the main brake as shown in Figure 1]
By arranging the stop lamp 10 in parallel with the stop lamp lighting circuits 1 and 1, an effect is produced in that the stop lamp 10 can be turned on even in a deceleration state.

In this case, it goes without saying that the deceleration sensor 1 must be arranged parallel to the traveling direction of the vehicle width.

As described above, according to the present invention, the stop lamp at the rear of the vehicle body is not illuminated not only when the main brake is depressed, but also when deceleration occurs, so that the following vehicle can maintain a safe distance and approach the vehicle. There are many things you can do to improve driving safety by preventing dangerous actions such as excessive braking, sudden braking, sudden steering, etc., and unexpected accidents such as rear-end collisions! This means that it can be improved in terms of v.
