Abstract

PURPOSE:To enable a drive switch for retracting or raising a head lamp to be individually operated in the order or changing over turning-off and retracting condition, turning-off and exposing one and turning-on and exposing one. CONSTITUTION:When a lighting switch 22 is in OFF position, head lamps 15, 16 are concealed to turn off a tail lamp 12 and head lamps 15, 16. When said switch is in UP position, retractor motors M1, M2 are started to expose the lamps without lighting the lamps. When said switch is in T position, the tail lamp 12 is lit and next, when it is in H position, the head lamps 15, 16 are also lit. Thus, the head lamps can be individually operated by a single control lever and turned off while exposed in cleaning a vehicle. Also, the head lamps are exposed so long as the switch is not in OFF position so that they can be lit immediately.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concealed headlamp device, and more particularly to a concealed headlamp device suitable for turning on/off and concealing and exposing a headlamp hidden in a vehicle body such as an automobile.

Concealed headlamps are generally hidden by the vehicle body when the headlamps are turned off, and exposed from the vehicle body by a drive motor (retractor motor) when the headlamps are turned on.

When the headlamp is hidden from the exposed state by the vehicle body, the headlamp is also driven to be concealed by the drive motor.

The concealed headlamp device needs to control the driving of the headlamp as well as control the turning on and off of the headlamp.

Therefore, devices have been proposed in which the driving and lighting of a headlamp can be controlled using a single operating lever.

However, this device is designed to prevent the headlights from being exposed due to freezing, and also to prevent the headlights from turning on if the headlights are left exposed for reasons such as washing the car. There are drawbacks.

In order to solve this problem, we have created an operating lever that can control the lighting and driving of the headlamp, and another operating lever that is separate from the operating lever, so that the control of the headlamp drive is independent of the function of the operating lever. A device has been proposed that is equipped with an operating lever.

However, in the case of this device, although it is possible to eliminate the drawbacks of the above device, it has the disadvantage that turning on, turning off, and driving the headlamp cannot be controlled with a single operating lever, which is an undesirable disadvantage in terms of operation.

The present invention has been made in order to eliminate the drawbacks of the conventional device, and provides a concealed headlamp device that can independently control turning on, turning off, and driving a concealed headlamp by operating a single operating lever. The purpose is to

The present invention provides a headlamp installed on a vehicle body so as to be concealed and exposed, a headlamp lighting circuit for lighting the headlamp, a motor for driving the headlamp to conceal or expose it, and a motor drive circuit for driving the motor. , a concealed headlamp device comprising a light switch that turns the headlamp on or off, and a retractor switch that turns the headlamp into a concealed or exposed state, an operation unit that commands switching operation of the light switch; An operating section for instructing switching operation of the retractor switch is integrated, and the switching order of the integrated operating section is a first state in which the headlamp is turned off and in a concealed state, and a first state in which the headlamp is turned off. The object is achieved by operating the light switch and the retractor switch according to the switching operation of the lighting switch, which is in a second state where the headlamp is turned on and is in an exposed state and a third state where the headlamp is turned on and the lighting switch is in an exposed state. This is what I did.

When the cathode of the diode D5 is grounded, the light retractor control relay circuit 10 connects the resistors R5 and R6.
Since a bias voltage is applied to the transistor Tr3 by the capacitor C3, the transistor Tr3 is turned on.

As a result, bias voltages are applied to the transistors Tr1 and Tr2 by the resistors R1, R2, R3, and R4, respectively, so that the transistors Tr1 and Tr2 are turned on.

When transistor Tr2 is turned on, relay 21 is driven and contact T21 is opened.

When the ground of diode D5 is opened, capacitor C3
Since the ON state of the transistor Tr3 is maintained for a certain period of time (about 2 to 4 seconds) by the charged electric charge, the contact T21 of the relay 21 closes after the certain period of time has elapsed.

FIG. 2 is a sectional view of a main part of the retractor motor shown in FIG. 1, with the headlamp exposed.

In FIG. 2, the final gear portion 3 of the retractor motor M1

s or insulating portion 17i.

In FIG. 2, the same or equivalent parts as shown in FIG. 1 are denoted by the same reference numerals.

Further, the retractor motor M2 has the same configuration as the retractor motor M1.

The action will be explained in detail below.

First, in the state shown in Figure 1, the lighting control lever is "OFF" and the daylight control lever is "HL".
position, and headlights 15 and 16 are hidden, battery 1 → fusible link 3 → coils L8 and L9 of brake relays 8 and 9 → contacts T19c and T2Qc of retractor switches 19 and 20 → down contact T
19d, T20d → Diode D1, D2 → Contact T21
The first loop circuit consisting of → contact OFF → ground is cut off because down contacts T19d and T20d are in contact with insulating parts 19i and 20i, and battery 1 → fusible link 3 → brake relays 8 and 9 Coil L8,
L9 → contact T19c of retractor switches 19 and 20,
The second loop circuit consisting of T20c→up contact T19u, T20u→+diodes D3, D4→contact UP→earth is also cut off because contact UP is open.

Therefore, since the retractor motors M1 and M2 do not operate, the headlamps 15 and 16 remain hidden.

Further, since the circuit between the tail lamp 12 and the head lamps 15 and 16 is also cut off, the tail lamp 12 and the head lamps 15 and 16 are turned off.

Next, when the lighting operation lever is set to the "UP" position, the contact UP is grounded, so the circuit of the second loop becomes energized, and the brake relays 8 and 9 are activated.
Contacts T8c and T9c switch to contacts T8a and T9a.

Therefore, the retractor motors M1 and M2 are started and the headlamps 15 and 16 are exposed in about 0.6 seconds.

At the same time, the sliding plates 19s, 20s of the retractor switches 19, 20 and the sliding plates of the light switches 17, 18 turn half a turn, and the insulating parts 19i, 20i of the retractor switches 19, 20 connect to the up contacts T19u, T20, respectively.
u and the sliding plates 17s of the light switches 17 and 18
, 18s contact the contacts T17a and T18a, respectively.

Up contacts T19u and T20u are respectively insulating parts 19i
, 20i, the circuit of the second loop becomes de-energized, and the contacts T8c and T9c switch to the contact T8.
b, to switch to T9b side, retractor motor M1,
Driving of M2 is stopped.

In addition, the sliding plates 17s and 18 of the light switches 17 and 18
s are in contact with the contacts T17a and T18a, respectively, but in this state, the headlamp relay 6 is not activated, so the headlamps 15 and 16 are turned off.

The tail lamp is also off because the tail lamp relay 5 is not activated.

Next, move the lighting control lever to the “T” position.
Contact UP1 and contact T are grounded.

Therefore, the tail lamp relay 5 is activated and the tail lamp 12 is turned on.

The headlamps 15 and 16 are turned off because the headlamp relay 6 is not activated in this state.

In addition, the contact OFF is in the open state, and the up contact T19u
, T20u are in contact with the insulating parts 19i, 20i, so the circuits of the first and second loops are in a non-energized state.

Therefore, the retractor motors M1 and M2 remain stopped.

Next, move the lighting control lever to the “H” position.
Since the contact T1 and the contact H are grounded, the headlamp relay 6 is activated and the low beam headlamps 15l and 16l of the headlamps 15 and 16 are turned on.

The tail lamp 12 remains lit.

At this time, if you set the deima control lever to "HU", the contact H
Since U is grounded, the day relay 13 is activated, and the headlamp 15u for the high beam of the headlamps 15 and 16 is activated.
, 16u lights up.

Furthermore, if the daylight operation lever is alternately switched between the "HL" and "HF" positions, the high beam headlamps 15u, 16u and the low beam headlamps 15l, 16l flash alternately in response to the switching operation.

Note that since the circuits of the first and second loops are in a non-energized state, the retractor motors M1 and M2 remain stopped.

Also, at this time, the diode D5 of the light retractor control relay circuit 10 is grounded, so the transistors Tr1, Tr2, and Tr3 are turned on, the relay 21 is activated, and the contact T21 is opened.

Contact T21 is in an open state when the lighting operation lever is in the "H" position, and the contact T21 is in an open state when the lighting operation lever is in the "H" position.
``After a certain period of time has elapsed after being released from the position, it returns to the closed state.

When the lighting control lever is returned to the “T” position, contact H
is opened and the contact T1 contact UP is grounded, so the bed lamps 15 and 16 are turned off.

Next, when the lighting operation lever is returned to the "UP" position, the contact T is opened and the contact UP is grounded, so that the tail lamp 12 is turned off.

Note that even if contact UP is grounded, retractor switch 1
Up contacts T19u and T20u of 9 and 20 are insulating part 19
i, 20i, the circuit of the second loop is de-energized and the retractor motors M1, M2 do not operate.

When the lighting control lever is returned to the "OFF" position, contact UP is opened and contact OFF is grounded, so the first loop circuit becomes energized, the retractor motors M1 and M2 start, and the headlamp 15 is turned on. , 16 are hidden.

At the same time, the sliding plates 19s, 20s of the retractor switches 19, 20 and the sliding plates 17s, 18s of the light switches 17, 18 turn half a turn, and the retractor switches 19,
The insulating parts 19i, 20i of 20 are down contacts T19d, T
20d and contacts Tl of light switches 17 and 18.
7a and T18a are insulating portions 17i. Contact 18i.

As a result, the circuit of the first loop becomes de-energized, so the retractor motors M1 and M2 stop.

Next, when the lighting operation lever is in the "OFF" position, bashing operation of the headlamps 15 and 16 can be performed by simply momentarily operating the daylight operation lever from the "HL" position to the "HF" position.

In other words, when the deima control lever is set to the "HF" position,
Since the contacts HF1 and HF2 of the dimmer switch 23 are grounded, the diode D5 of the light retractor control relay circuit 10 is grounded, and the transistors Tr1 and Tr
2. Tr3 turns ON.

When the transistor Tr1 is turned on, the retractor motors M1 and M2 are started by the same effect as when the lighting operation lever is changed from the "OFF" position to the "UP" position.
Head bumps 15, 16 are exposed.

Also, at this time, since the contacts HF1 and HF2 are grounded, the headlamp relay 6 and the dimmer relay 13 are activated, and the headlamps 15u, 15u, for high beam of the headlamps 15, 16 are activated.
16u lights up.

Note that the contacts T19c and T20c of the retractor switches 19 and 20 and the down contacts T19d and T20d are brought into conduction by the operation of the retractor motors M1 and M2, but when the transistor Tr2 is turned on, the relay 21 is activated and the contact T21 is opened. becomes the state of

Therefore, the circuit of the first loop becomes de-energized, and the driving of the retractor motors M1 and M2 is stopped.

The Deima control lever is returned to the “HL” position and the ridge point HF is
1. Even after HF2 is opened, the transistor Tr3 remains on for a certain period of time (about 2 to 4 seconds) due to the charge in the capacitor C3.

Therefore, if you operate the daylight control lever back and forth between "HL" and "HF" within this time, the headlamp relay 6
Since the daylight relay 13 turns ON and OFF simultaneously according to the operation, the high beam headlamps 15u and 16u of the headlamps 15 and 16 blink.

The last bashing operation using the Dayma control lever is completed (
After a certain period of time has elapsed (2 to 4 seconds later, the contacts HF1 and HF2 are open), the transistors Tr1, Tr2,
Tr3 is turned OFF, the operation of relay 21 is stopped, and contact T21 is closed.

Therefore, the retractor motors M1 and M2 are started by the same action as when the lighting control lever is changed from the "UP" position to the "OFF" position, and the headlamps 15, 16 are activated.
After the retractor motors M1 and M2 are hidden, the retractor motors M1 and M2 stop driving.

Also, turn the lighting control lever from the “H” position to the “OF” position.
Even if it is returned to the "F" position all at once, the contact T21 of the relay 21 will not close until a certain period of time has elapsed, so the headlamp 15
, 16. After the tail lamp 12 is turned off, the retractor motors M1 and M2 are driven and the head lamps 15 and 16 are hidden.

! Note that this embodiment can also be applied to a device in which the retractor motor rotates in forward and reverse directions, or a device in which the cover that covers the headlamp body is driven by the retractor motor.

As explained above, if the concealed headlamp device according to the present invention is used, the headlamp can be turned on, turned off, concealed, and exposed independently with a single operating lever.
Furthermore, the operation procedure does not give a sense of discomfort, and even when the headlights are left exposed for car washing or the like, there is an excellent effect that the headlights can be kept in the off state.

Furthermore, when trying to turn on the headlights, UP
Even if the headlamp is exposed by changing the position,
This does not go to waste, and if you switch to the H position, you can immediately turn on the headlights to provide illumination, and even if you temporarily turn off the headlights, the headlights will remain exposed unless you return them to the OFF position. This also has the effect of being able to instantly turn on the light again.
