JPS6085036A - Automatic light-on/off apparatus of automobile's head lamp - Google Patents

Abstract

PURPOSE:To prevent careless ignorance of lighting off a head lamp and enable safety drive at night in the crowded and snarl traffic by lighting on the head lamp when revolution wheels, namely, driving state is sensed and on the contrary, lighting off the head lamp when interruption thereof, namely, stoppage of a vehicle is sensed. CONSTITUTION:Revolution of a wheel transmitted via a flexible shaft causes a rotary magnet 12 to produce an eddy current proportion to the revolution speed inside a yoke 13, thereby making the indicator 14 on a meter turn. When the indicator 14 reads O, the switch of a head lamp power circuit is open and when the wheel starts turning to turn the lever of the indicator, the switch is closed to supply the head lamp 20 with the power of a battery 17 so as to light up the lamp 20 via a head lamp switch 19. A manual/automatic changeover switch 21 is provided in parallel with the switch. When the switch 21 is closed, the head lamp 20 may be lighted on and off through operation of the head lamp switch 19.

Description

[Detailed description of the invention] This IUJ automatically extinguishes the headlights (upward and downward) of a car when it stops at traffic lights, intersections, etc. when driving at night, and starts driving. This relates to a device that automatically turns on the light.

Traditionally, headlights, which have been self-provisioned, have been used to make driving safer by turning them on when it gets dark while driving.However, in recent years, the number of cars has increased, and due to traffic lights, congestion, traffic jams, etc. In many cases, it is not possible to drive smoothly. Therefore, in such conditions, cars often run or stop. When the engine is stopped, the engine rotates at low speed, and the voltage generated by the charging w1 J & [ (dynamo) becomes lower than the battery voltage, and the cut-out relay operates and the electricity charged in the battery is discharged. If this state continues for a long time, the battery will run out of electricity. For this reason, it is necessary to repeatedly turn off the front Mffl when the vehicle is stopped and turn it on when departing.If the vehicle repeatedly starts and stops for a long time due to traffic jams, accidents, etc., the headlights must be turned on and off in the same way. You have to do it repeatedly. Flashing is troublesome, so driving with the smoke off can cause an accident, and repeatedly starting and stopping with the light on can cause damage to the car.

This invention automatically turns on the headlights while driving and automatically extinguishes the smoke when the vehicle stops, eliminating the hassle of manual flashing, preventing traffic accidents, and further reducing traffic accidents. In addition to prevention, it also makes it possible to prevent the occurrence of faults in the automobile's electrical system.

The basic idea of this invention is to detect the rotation of the car's wheels, i.e., when the car is running, and activate the electrical circuit of the headlights to turn on the smoke, and when the rotation stops, the smoke is extinguished if the car is only running for one hit. there is.

The rotary drive parts of an automobile are explained with reference to Fig. 1.The parts that rotate directly connected to the engine include the engine 1, the flywheel 2, the clutch mechanism 3, a part of the gear on the transmission drive side, and the E axle that is directly connected and rotates. parts” namely axle 5, differential gear 6, propeller gear 7
7.7. Transmission shaft parts are classified into two parts: (1) The present invention is characterized by attaching a mechanism for sensing rotation to any part of the rotating part directly connected to the latter axle, or The rotation is extracted from the part, the rotation is sensed at a predetermined place, and the headlight circuit opens and closes, that is, blinks.
This method is the same for automatic clutches, torque converters, etc.

An easy way to actually sense the rotation and blink the headlights is to install an opening/closing mechanism for the 1rII blinking lights inside the speedometer. Speedometers include centrifugal type, magnetic type, photoelectric pulse sensing digital type, etc., but we will explain using an example where a switch is attached to the most common type, magnetic type (electromagnetic type).

In Figure 2, a worm gear is placed on the main shaft 9 of the transmission, and the rotation of the wheels is transmitted to the speedometer via the flexible shaft IL. FIG. 3 is a diagram showing the structure of the speedometer. The rotation transmitted from the flexible shaft 11° is transmitted to the rotating magnet 12. Turn the yoke 13. The meter pointer 14. Turn it in the direction of arrow A. Since eddy current is generated in proportion to the rotational speed, the speed can be indicated by the magnitude of the torque applied to the pointer. When it does not rotate, no rotational trigger occurs, the pointer points to 0 as shown in Figure 4, and the blinking power source for the headlights is switched to switch 16. The circuit from arrow A to arrow A is closed inside, but if it starts rotating, the pointer lever 16. 15. Move in the direction of arrows B and Q. An electric light flows through the circuit from arrow A to arrow A, and the headlights are turned on.

FIG. 5 is a schematic diagram showing the current circuit of the 611 light, including the battery 17 and the switch 18 in the speedometer. Pass through the headlight switch 19. After passing through, the front light is turned on, and current flows to the battery 17.12. Circuit arrows c, , , g shown by dotted lines are used to set up a short circuit at switch 21.
If you install this circuit, you can open it to use the conventional manual light, and close it to switch to an automatic flashing light.

These automatic flashing devices can be attached to centrifugal and photoelectric pulse digital speedometers as well.

As mentioned above, by installing an opening device that detects rotation in the rotating part that is directly connected to the wheel, the headlights can be turned on and off when the vehicle is moving, and the smoke is extinguished when the vehicle is stopped, making it easier to use during congestion or traffic jams. Since the rapid blinking is done automatically without depending on the hand, it is useful for safe driving at night without forgetting to turn it off, and it is impossible to protect the car from tR faults in the electrical system.
