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/exposing a headlamp concealed in a vehicle body such as an automobile.

Concealed headlamps are generally hidden in the vehicle body when the headlamps are turned off, and when they are turned on,
It is exposed from the vehicle body by the drive motor (retractor motor). When the headlamp is concealed from the exposed state in the vehicle body, the headlamp is driven to be concealed by the drive motor. The concealed headlamp device needs to control the driving of the headlamp as well as 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 and turned on due to freezing, and also has the disadvantage that if the headlights are left exposed for car washing, etc., the headlights will remain on. be. Therefore, in order to solve this problem, we have created an operating lever that can control the lighting and driving of the headlamp, and an operating lever that is separate from the aforementioned operating lever, so that the control of the driving of the headlamp is independent of the function of the aforementioned operating lever. A device has been proposed that is equipped with an operating lever. However, although this device can overcome the drawbacks of the above devices, 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 drawback in terms of operation.

Further, in the concealed headlamp device, there is a problem in that if the headlamp is irradiated while the irradiation of the headlamp is being exposed and concealed, it will give a dazzling light to the driver of the vehicle, especially oncoming vehicles.

The present invention has been made in order to eliminate the drawbacks of the conventional device, and it is possible to independently control the lighting, extinguishing and driving of a concealed headlamp by operating a single operating lever, and to completely eliminate the concealed headlamp. It is an object of the present invention to provide a concealed headlamp device that does not turn on the headlamp unless it is in an exposed state and that can efficiently perform these functions.

The present invention provides a plurality of independent headlamps that are installed on a vehicle body so as to be hidden and exposed, a headlamp lighting circuit for lighting the headlamps, a plurality of motors for driving the headlamps to be concealed or exposed, and a plurality of motors for driving each of the motors. a motor drive circuit; a light switch inserted into the motor drive circuit to switch the headlamp on or off; a retractor switch inserted into the motor drive circuit to switch the headlamp into a concealed or exposed state; An operating section for instructing a switching operation of the light switch and an operating section for instructing a switching operation for the retractor switch are integrated, and the switching order of the integrated operating sections is such that the headlamp is off and in a concealed state. a lighting switch that is in a first state, a second state in which the headlight is off and exposed, and a third state in which the headlight is on and exposed; the light switch and the retractor are in a third state; Both switches are sliding switches that rotate and slide by a predetermined amount in conjunction with the rotational drive of the motor according to the switching operation of the lighting switch, and each headlamp is exposed or hidden during the sliding period of the predetermined amount, The above object is achieved by configuring the light switch to close each headlamp lighting circuit at the end of its sliding motion, and the retractor switch to close each motor drive circuit at the end of its sliding motion. This is what I did.

Transistors Tr1 and Tr2 are connected to resistors R1 and Tr2, respectively.
Since a bias voltage is applied through R2, R3, and R4, 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 the diode D5 is opened, the charge of the capacitor C3 causes the transistor Tr3 to remain open for a certain period of time (about 2 to 4 seconds).
Since the ON state of is maintained, the contact T21 of the relay 21 closes after a 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 30 of the retractor motor M1 includes a final gear 3.
The sliding plate 19s of the retractor switch 19 and the sliding plate 17 of the light switch 17 rotate in synchronization with the retractor switch 1.
s is provided. The final gear 31 is a gear having a constant reduction ratio with respect to the gear for driving the headlamps 15 and 16, and rotates by half a rotation when the retractor motor M1 drives the headlamps 15 and 16 to hide or expose them. Sliding plate 1 of retractor switch 19
9s is provided with an insulating part 19i, and the contact T
19c, down contact T19d, up contact T19
u are arranged so as to contact the sliding plate 19s or the insulating portion 19i, respectively. light switch 1
The contact T17b of No. 7 is arranged so as to be always in contact with the sliding plate 17s, and the contact T17a is arranged so as to be in contact with the sliding plate 17s or the insulating part 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, when the lighting operation lever is in the "OFF" position, the dimming operation lever is in the "HL" position, and the head lamps 15 and 16 are hidden, as shown in FIG. Usable link 3→
Coils L8, L9 of brake relays 8, 9 → contacts T19c, T2 of retractor switches 19, 20
The first loop circuit consisting of 0c → down contacts T19d, T20d → diodes D1, D2 → contact T21 → contact OFF → ground is down contact T19
d and T20d are in contact with insulating parts 19i and 20i, so they are cut off, and battery 1 → fusible link 3 → coil L of brake relay 8, 9
8, L9 → Contacts T19c, T20c of retractor switches 19, 20 → Up contacts T19u, T2
The second loop circuit consisting of 0u → diodes D3 and D4 → contact UP → ground 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 second
The loop circuit becomes energized, brake relays 8 and 9 operate, and contacts T8c and T9c are connected to contact T.
8a, switches to T9a side. Therefore, the retractor motors M1 and M2 start and the headlamp 1
5 and 16 are exposed in about 0.6 seconds. At this time, at the same time, the sliding plates 1 of the retractor switches 19 and 20
The sliding plates of 9s, 20s and light switches 17, 18 turn half a turn, and the retractor switches 19, 20
The insulating parts 19i and 20i are respectively up contacts T.
Contact 19u and T20u, light switch 1
7 and 18 sliding plates 17s and 18s are in contact with contacts T17a and T18a, respectively. Up contact T1
9u and T20u are insulating parts 19i and 20i, respectively.
By contacting the retractor motors M1 and M2, the circuit of the second loop becomes de-energized and the contacts T8c and T9c are switched to the contacts T8b and T9b, so that the driving of the retractor motors M1 and M2 is stopped. Although the sliding plates 17s and 18s of the light switches 17 and 18 are in contact with the contacts T17a and T18a, respectively, the headlamp relay 6 is not activated in this state, 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, when the lighting operation lever is moved to the "T" position, the contact UP 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
In this state, the headlamp relay 6 does not operate, so the light is turned off. In addition, the contact OFF is in the open state, and the up contacts T19u and T20u are in the insulating part 1.
9i and 20i, so the first and second
The loop circuit is de-energized. Therefore,
Retractor motors M1 and M2 remain stopped.

Next, when the lighting operation lever is set to the "H" position, contacts T and H are grounded, so the head lamp relay 6 is activated and the head lamps 15 and 1 are turned on.
Headlamp 15l, 16l for low beam of 6
lights up. The tail lamp 12 remains lit. At this time, if you set the daylight operation lever to "HU", the contact HU will be grounded, so daytime relay 1
3 is activated, and the high beam headlamps 15u, 16u of the headlamps 15, 16 are turned on.
Furthermore, if the dimmer operating 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,
M2 remains stopped. Also, at this time, since the diode D5 of the light retractor control relay circuit 10 is grounded, the transistor Tr
1, Tr2, and Tr3 are turned ON, the relay 21 is activated, and the contact T21 is opened. The contact T21 remains open while the lighting operation lever is in the "H" position, and returns to the closed state after a certain period of time has elapsed since the lighting operation lever was released from the "H" position.

As mentioned above, turn the lighting control lever,
When set to “UP” position, light switches 17, 18
each headlamp 15, 16 at the end of its sliding.
The lighting circuit of the retractor switch 1 is closed, and the retractor switch 1 is closed.
7 and 18 cut off each motor drive circuit at the end of the sliding, and the head lamps 15 and 16
The head lamps 15 and 1 are prevented from being irradiated during the exposure/concealing operation, but even when the lighting switch 22 switches from the first state to the third state at once, the head lamps 15, 1
It is possible to prevent the lamp from being irradiated during the exposure/concealment operation in step 6.

When the lighting operation lever is returned to the "T" position, the contact H is opened and the contacts T and UP are grounded, so that the head 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. In addition,
Even if contact UP is grounded, retractor switch 1
Since the up contacts T19u and T20u of 9 and 20 are in contact with the insulating parts 19i and 20i, the second
The loop circuit is in a de-energized state, and the retractor motors M1 and M2 do not operate.

When the lighting operation 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 head lamps 15, 16 is hidden. At the same time, the sliding plates 19 of the retractor switches 19 and 20
s, 20s and the sliding plates 17s, 18s of the light switches 17, 18 rotate half a turn, the insulating parts 19i, 20i of the retractor switches 19, 20 contact the down contacts T19d, T20d, and the light switch 1
Contacts T17a and T18a of 7 and 18 are insulating part 17
i, 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 operating lever is in the "OFF" position, the passing operation of the headlamps 15 and 16 can be performed by simply operating the daylight operating lever from the "HL" position to the "HF" position for a moment. That is, when the daylight operation lever is set to the "HF" position, the contacts HF1 and HF2 of the daylight switch 23 are grounded, so the diode D5 of the light retractor control relay circuit 10 is grounded, and the transistors Tr1, Tr2, and Tr3 are turned on. When the transistor Tr1 is turned on, the retractor motors M1 and M are activated by the same action as when the lighting control lever is changed from the "OFF" position to the "UP" position.
2 is started and the headlamps 15 and 16 are exposed. Also, at this time, since contacts HF1 and HF2 are grounded, head lamp relay 6 and daylight relay 13
is activated, and the high beam headlamps 15u, 16u of the headlamps 15, 16 are turned on. Note that the contacts T19c and T19c of the retractor switches 19 and 20 are activated by the operation of the retractor motors M1 and M2.
T20c and the down contacts T19d and T20d are in a conductive state, but when the transistor Tr2 is turned on, the relay 21 is activated and the contact T21 is in an open state. Therefore, the circuit of the first loop becomes de-energized, and the retractor motors M1 and M2
drive will stop. Deima control lever is “HL”
Even after the contacts HF1 and HF2 are 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 the dimmer control lever is operated back and forth between "HL" and "HF" during this time, headlamp relay 6 and dimmer relay 13 will turn ON and OFF simultaneously according to the operation, so the high beam of headlamps 15 and 16 will be turned on and off. head lamp 15
u, 16u blinks.

After the last passing operation using the deima control lever is completed (contacts HF1 and HF2 are open),
After a certain period of time (after 2 to 4 seconds), transistors Tr1, Tr2, and Tr3 are turned off, the relay 21 is deactivated, and the contact T21 is closed.
Therefore, after the retractor motors M1 and M2 are started by the same action as when the lighting operation lever is changed from the "UP" position to the "OFF" position and the headlamps 15 and 16 are hidden, the retractor motors M1 and M2 are driven. stops.

Furthermore, even if the lighting control lever is returned from the "H" position to the "OFF" position all at once, the contact T21 of the relay 21 will not close until a certain period of time has elapsed.
After the lights go out, the retractor motors M1 and M2 are driven and the headlamps 15 and 16 are hidden.

In addition, the retractor motor rotates forward and backward,
Alternatively, this embodiment can also be applied to a device in which a cover covering a headlamp body is driven by a retractor motor.

As explained above, if the concealed headlamp device of the present invention is used, the headlamp can be turned on, turned off, concealed, and exposed independently using a single operating lever, and the operation procedure does not cause any discomfort. Additionally, even when the headlights are left exposed for car washing or the like, there is an excellent effect in that the headlights can be kept in an off state. Furthermore, when trying to turn on the headlamp, even if the headlamp is exposed by passing through the UP position, this will not be wasted; conversely, if you switch to the H position, the headlamp will be turned on immediately for illumination. Another advantage is that even if the headlamp is temporarily turned off, it remains exposed unless it is returned to the OFF position, so it can be turned on again immediately. Moreover, if the concealed headlamp device according to the present invention is used, the left and right headlamps will not turn on unless they are completely exposed even if the lighting switch is switched from the first state to the third state at once. In particular, even in a vehicle equipped with a headlamp in which the irradiation surface of the headlamp is exposed from the upper side of the vehicle toward the front, there is an effect that dazzling light will not be emitted to oncoming vehicles. Since the light switch and the retractor switch are sliding switches that are linked to the rotational drive of the motor, the various controls described above, the closing operation of the headlamp lighting circuit, and the opening and closing operation of each motor drive circuit are performed by one operation lever. It has the advantage that it can be done efficiently.
