Description

Head Lamp Automatic Switching Device

The present invention relates to a headlamp automatic switching device, and in particular, by attaching a sensor for measuring the intensity of the beam output from the oncoming vehicle to detect the intensity of the beam, if the oncoming vehicle is analyzed to turn on the upstream headlamp The present invention relates to a headlamp automatic switching device characterized by providing a convenience in that the driver does not need to operate the dimmer switch every time by configuring an apparatus for automatically switching the lamp to a downward headlamp.

In general, automobiles are equipped with various lamps, such as headlamps necessary to illuminate the front at night, direction indicator lamps to recognize the direction of rotation to other drivers, and reverse lamps that illuminate the rear object when reversing. Lamps are installed for safe operation.

Referring to the circuit configuration required to irradiate the headlamps among the vehicle lamps as shown in FIG. 1, the ignition switch 1, which is a switching key for operating the engine of the vehicle, and the mechanical operation of the ignition switch 1 are electronic. Starting relay 2 for switching to normal operation, battery relay 4 for contacting the main power source of battery 3 by the operation of the starting relay 2, and power supply of the battery through the battery relay 4 A starting motor 5 that is supplied to start the engine for operation, an alternator 6 that rotates correspondingly when the engine is rotated by the operation of the starting motor 5, and receives power from the battery or the alternator head. The head lamp relay (7) for delivering the main power to the lamp circuit stage, and the power supply of the head lamp relay to the head lamp, the up lighting state and the down lighting state A dimming switch 8 to be distinguished, an upstream head lamp 9-1 which is turned on in correspondence with a switching operation of the dimmer switch, and is turned on in correspondence to a switching operation of the dimmer switch and is turned down according to a switching operation of the dimmer switch. It consists of a downward headlamp (9-2) which is operated at the time.

The headlamp power supply device configured as described above requires the start switch 1 to output the power of the first battery 3. The battery 3 provides a rotational force for operating the engine by applying initial power to the start switch 1 via the battery relay 4.

Therefore, if the power of the battery (3) is all discharged, the power is not applied to the starter motor (5), which can not operate the engine can not operate the vehicle.

On the other hand, when the engine is operated by the power supply of the battery 3, and then the alternator 6 is operated, since the AC power is supplied from the alternator 6 to various electric devices, the power of the battery 3 is no longer used. .

In addition, since the battery 3 power supply and the alternator 6 are connected in parallel to supply electrical energy to each electric device, even if the alternator 6 is not operated, various electric appliances can be driven using the power supply of the battery 3. .

Accordingly, the headlamp relay 7 connects the power output from the battery 3 or the alternator 6 to the headlamp circuit stage by the ignition switch 1. Thereafter, when the driver turns on the dimmer switch 8, which is a head lamp operation switch, the head lamps 9-1 and 9-2 are turned on. In addition, the headlamp has an upward lighting state that illuminates a long distance and a downward lighting state that illuminates a short distance. When the dimmer switch 8 is operated in an upward mode, the upper headlamp 9-1 is kept on and the dimmer When the switch 8 is operated in the down mode, the down head lamp 9-2 is kept low.

Therefore, such a circuit configuration operates the dimmer switch 8 in the up mode when the long distance is to be illuminated at night, and operates the dimmer switch 8 in the down mode when the other vehicle approaches or illuminates the close distance. It is necessary because it must. Because bright light located in front of the car is irradiated to the driver, the driver may not be able to identify the object in front, so when approaching other vehicles must be switched to the down light or off state to reduce the risk of accidents.

However, while driving with an upstream headlamp on a secluded road or on a road without a street lamp with a vehicle equipped with such a device, when the vehicle coming from the other side turns on the upper headlamp and keeps the headlamp on, At this time, there was an inconvenience to operate the mode of the headlamp every time for the safety of other vehicles.

The present invention is to solve the above problems, the headlight is detected when the other vehicle is turned on the headlamp as a result of detecting the beam of the oncoming vehicle by adding a sensor for detecting the intensity of the beam of the oncoming vehicle. Automatically switch to the down mode, and automatically configures the device to operate in the up mode when the vehicle leaves.

As a means for achieving the above object, the optical sensor for detecting the beam of the relative vehicle, the relay circuit portion for controlling the on-off of the up-light lamp and the direction-light lamp according to the action of the light sensor and the power supply to the relay circuit portion It comprises a power applying means for applying a.

Hereinafter, described in detail with reference to the drawings.

FIG. 2 is a schematic diagram of the present invention, which detects a beam of an oncoming vehicle and detects a beam of an upstream headlamp. And a first magnetic induction coil 12-1 which causes a magnetic induction phenomenon and a downward head lamp switch 12-2 which is led to the magnetic induction coil 12-1 to light the downward head lamp 9-2. And a first relay circuit portion 12 including a first circuit connection switch 12-3 for turning on and off an electric current flowing through the upstream headlamp 9-1, and an upstream switch for turning on the first upstream headlamp. A headlamp switch 13, a second magnetic induction coil 14-1 conducting corresponding to the on operation of the upward headlamp switch 13 and causing a magnetic induction phenomenon, and the magnetic induction coil 14-1. To the second circuit connecting means 14-2, which is led to the upper headlamp 9-1. And a second relay circuit section 14 and power supply means 15-1, 15-2, and 15-3 for applying power to the circuit section.

According to the present invention configured as described above, when the first upward headlamp switch 13 is operated, voltage is induced in the second magnetic induction coil 14-1 so that the second connection switch 14-2 contacts the power supply means ( The voltage of 15-1) is transmitted to the upstream headlamp 9-1 so that the upstream headlamp 9-1 is turned on.

On the other hand, when the oncoming vehicle approaches the state in which the headlamp is turned on, the optical sensor 11 conducts. When the optical sensor 11 conducts, the voltage is induced to the first magnetic induction coil 12-1. This immediately turns off the first circuit connecting means 12-3, and turns off the upward headlamp 9-1. At the same time, the downward headlamp 9-2 is turned on by contacting the downwardly lit switch 12-2.

After that, when the oncoming vehicle passes through the host vehicle, the light sensor 11 stops the electric flow of the circuit again so that no voltage is induced in the first magnetic induction coil 12-1, and thus the downward headlamp switch 12- 2) returns to its original state, and stops the flow of current through the downward headlamp 9-2, so that the downward lamp 9-2 is turned off. At the same time, the first circuit connection switch 12-3 is brought into contact with each other to induce a voltage to the upward headlamp 9-1, thereby turning on the upward headlamp 9-1.

At this time, if the oncoming vehicle turns on the lower headlamp, it is not detected by the light sensor, and thus the host vehicle maintains the upper headlamp.

Therefore, when the present invention is used, the driver may automatically switch the up and down headlamps according to the degree of headlamp lighting of the oncoming vehicle, so that the driver does not need to operate the dimmer switch separately.

As described above, the present invention provides a convenience in that the driver does not have to operate the dimmer switch every time by configuring an apparatus for automatically switching the upstream headlamp to the downhead lamp when the oncoming vehicle is analyzed with the upstream headlamp turned on. It works.
