Abstract

PURPOSE:To transmit the intention of overpassing or right turn to a driver in a car ahead or facing opposite without delay by providing a light control means to light head lamps simultaneously with the operation of passing. CONSTITUTION:When a passing switch 4 is on, a transistor 16 in a unit 15 is on, and head lamps 3R and 3L are lit by the excitement of coils 17 and 18. Simultaneously, contacts in relays 11R and 11L are set to the side (b) via opening/closing detection switches 10R and 10L, and head lamps 3R and 3L are started to move to opening positions by rotations of drive motors 12R and 12L for informing of the will of a driver in an instant. When they are brought to full opening positions, switches 10R and 10L are switched over to the DOWN side, and at the same time, head lamps 3R and 3L are turned off to start closing operation. This construction permits to transmit the intention of overpassing or right turn to a car ahead or facing opposite without delay.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tractor-pull headlamp opening/closing control device (1KII) that quickly transmits the passing intention when a passing operation is performed to convey the intention of overtaking to an external vehicle.

It is a must to store the headlamp inside the vehicle inside the vehicle. Depending on the situation, some are equipped with upward-facing lights or tractor-pull headlamps.

On the other hand, many vehicles are equipped with a passing function that allows the headlamps to light up or flash in an upward beam to notify the vehicle in front of the JK vehicle traveling ahead. It is being

lights up and the headlamp '3B' is in the 2nd position.

3L is now ready to light up. 4 is a passing switch that is turned on when overtaking a vehicle in front, and 5 is a main/dimmer switch that switches between the main (high beam), M, and ima (low beam) D of the headlamp; these switches 4 and 5 are normally the lighting switch 1. It is operated with the operating lever 6, and the operating lever 1
When you pull it to the bashing position, the passing switch turns on, and when you push the Dayma D1 forward in the neutral position, it becomes the main M, and even if the operating lever is set to the bashing position, it does not stay in that position and automatically returns to the neutral position. There is. Main day!
The selector switch 5 is off when the operating lever is in the neutral position 6, and at this time the contact 61 of the relay 6 is gay!

R$ 10 L&1DQW switches to the plow point, and as a result, the contacts of relays 11R and IIL return to IK again, so
The power supply to the drive motors 11R and 12L is cut off, and one revolution of the drive motors is stopped.

When the hand 11Ml11 switch 7 is set to the closed (Dω) position, since the relay 8 is normally w3 grade 8, the signal is transmitted via the -patch gland detection switches 10R and 10L (at this time, the contacts are connected to the DOW contacts). Since the coils Kll of the relays 11R and IIL flow, the drive motors 12R and 12L turn around in the same way as in the case of the NI/jJ product described above, and the headlamp 3R is activated.

3L moves to the closed position. Head Lung 3R.

When 3L reaches the complete klEi level IkK, rIa Nobo 1 detection switch 10 mice, IOL discussion is UP! Since it switches to point &, the power supply to the drive motor is cut off and its rotation stops.

# of Head Lung 3 Rv 3 L! The j%'l# operation is performed not only when the manual opening/closing switch is operated as described above, but also when the lighting switch 1 is set to the second position. Therefore, a case will be described in which the lighting gear is set to the 1tr 2nd stage position and the column-shaped lever is pushed forward, that is, the case where the head rung is set to main ThM&C.

When you set lighting switch 1 to the 2nd position and push the column-shaped lever forward, the main day! The changeover switch 5 is turned on and the contact 6m of the relay 6 contacts the main function MK, so the head rank is 3R.

At this time, contact IB of relay 8 is off, so even if manual close switch 7 is closed (DOWN)
Even if they are in the same position, the driving force and the driving force will not rotate at the same time.

When the lighting switch 1 is returned to the OFF position, the headlamps 3R and 3L% and the taillights 2 are turned off and the contact point of the relay 8 is turned on again, so the manual open/close switch 7 is closed (
DOWN) position, relays 11R and 11R and
Since L is energized, the motor rotates again and moves the headlamps 3R, 3L to the closed position.

Next, the above 11! during the passing operation! Considering the operation of the I-close-a circuit, no matter what position lighting switch 1 is in, if you pull the column-shaped lever toward you and perform a passing operation, passing switch 4 is turned on, and head rung 3R, 5LFc* 1*B to 1lIIl
At the same time, the passing signal is sent to the passing unit 9.
Please enter the information below. At this time, headlamp 3R,! Lamp switch 14R connected in series to the IL main circuit,
Since the headlamp 14L is off because the headlamp is in the closed position, the headlamps 3R and 3L do not light up. The CR timer of the passing unit 9 is driven by the input of the passing signal, and is transmitted for a certain period of time via the line L.
Outputs H level signal. At this time, since the headlamp is in the open position, the open/close state detection switch 10R, IOL
Since the contact is at the up contact, tie auto D2. D3,

1R and 11L are energized, their contacts are switched from 1 to bK, and the drive motors 12R and 12L rotate. In this way, the headlamps 3R and 3L move toward the open position 6°. After that, when the headlamps 3R and 3L reach the open position, the optical axis of the headlamp becomes horizontal, and the lamp switches 14R and 14L are turned on, and the headlamp switches 14R and 14L are turned on. Lamp 3R, 3
The open state of L will continue for a certain period of time determined by the time constant of the CR timer of the passing unit 9 * 6 degrees When the passing operation is performed on this 8, the headlamps 3R and 3L will be lit as the main lights,
The lights of the headlamps 31R and 3L are directed in the horizontal optical axis direction, and if the passing operation is repeated, they will blink and perform the passing function. Figure 2 shows the relationship between the KR shing operation and the resulting headlamp lighting.

By the way, passing operations can be done relatively slowly on highways, etc., but in places such as urban areas where the distance between vehicles is relatively small and oncoming vehicles frequently come by, passing the vehicle in front must be done within a short period of time. Because of this, you should use passing maneuvers to let the vehicle in front know your intention to overtake as quickly as possible! j! , it is necessary to tell. Also, passing #a# is not the original usage, but when you are about to turn right at an intersection, you may go straight and use the passing operation to make oncoming cars aware of your vehicle. Naba f! Also, it is necessary to turn on the headlights as quickly as possible by using a passing maneuver to notify the other party.

However, with the above-mentioned conventional tractor-pull headlamp, as shown in Figure 2, the headlamp begins to move to the open position with the first passing operation, and the lamp switch remains off until the headlamp reaches the fully open position. Therefore, even if you perform a passing operation before that, the headlights will not turn on, and only when you perform a passing operation after reaching the open position, will the headlamps turn on and the passing operation will take place. In order to avoid this, it is inevitable that it will take some time after the passing operation until the driver's intention is transmitted to the vehicle in front or oncoming vehicle.The present invention has been made in view of the above points, and When this happens, move the head rung to the open position, and after reaching the open position, move it to the heir position and move it to the retractable arm. It was designed to light a lamp.

The present invention will be described in detail below based on the drawings.

FIG. 3 shows an embodiment of the 69 tractor pull head opening/closing control circuit according to the present invention, in which the same reference numerals as in FIG. 1 indicate the same components. The passing operation instantly turns on the headlamps BB and SL, and at the same time as 6, the driver 11i1 motor 1

The contacts of relays 11R and 11L are switched from a to b via 10L (located at point UPifi!e at this time), drive motors 12R and 12L start rotating, and headlamp 3R
, since the 3L starts to open, the driver's intentions can be instantly notified to the outside world. In this way, the drive motors 12R, 12L' continue to turn for 1 m, and when the headlamps 3R, 3L reach the fully open position, the open/closed state detection switches IOR, IOL switch to the DOWN m point, and the unit 15 VT!

Since X (7f8W) of Sa is turned on, drive motors #12R and 12Lbi continue to rotate from unit Is to line L, % manual close switch 7, FM closed state detection switches IOR and IOL, and relays 11R and IIL. The headlamps SR and SL start opening operation.In addition, the DOWN operation is performed from the open/closed state detection switches IOR, IOL or the UPI point.
At the instant of switching to contact, the contacts of relays 11R and IIL switch from open -1 to bK, so the level of line L4 changes from #H# to #L1.

Unit 15 i! When the 111111iI circuit 15 receives this #L# signal fl1BH, it lowers the base potential of the transistor 16, making the transistor 16 non-conducting.

l * Ryl comes on, the power supply to the headlamps 3R and SL stops, and the headlamps 3R and 3L turn off.In this way, according to Honjitsu Kai, the opening operation of the headlamps starts at the same time as the passing operation. The headlights light up to immediately notify the vehicle ahead of your intention to overtake. be able to. The flashing of the headlights during passing may be performed manually by the driver, or may be performed using the flashing unit 1 and a flashing signal automatically transmitted from the flashing unit 1. Further, the headlamp can be turned off during passing when the passing operation is canceled or when the headlamp reaches the completely open position.

As explained above, in the present invention, when a passing operation is performed, the headlamp is turned on and driven together with the cello, so that the headlamp is completely opened.
The light turns on when the driver reaches K, and the driver's intention to overtake or turn right is communicated to the assisting vehicle or oncoming vehicle without any delay, so the passing function is useful in places such as urban areas where overtaking must be done quickly. can be fully demonstrated.
