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 the body of an automobile or the like.

A concealed headlamp device is concealed in the vehicle body when the headlamp is turned off, and is exposed from the vehicle body by a drive motor (retractor motor) when the headlamp is turned on. 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 has the disadvantage that if the headlamp is left exposed to prevent the headlamp from being turned on due to freezing, or if the headlamp is left exposed for car washing, the headlamp will remain on. 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 headlamp drive can be made independent of the function of the operating lever. A device has been proposed that is equipped with an operating lever that can perform the following operations. 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.

The present invention has been made in order to eliminate the drawbacks of the conventional devices, and an object of the present invention is to provide a concealed headlamp device that can turn on and off the headlamp and drive the concealed exposure by operating a single operating lever. do.

The present invention includes a headlamp installed in a vehicle body so as to be hidden or exposed, a headlamp lighting circuit that controls power supply to the headlamp, a lamp switch that controls the operation of the headlamp lighting circuit, and a headlamp that can be hidden or exposed. In a concealed headlamp device comprising a headlamp drive switch for switching, a motor for driving the headlamp to conceal or expose it, and a motor drive circuit for driving the motor, the lamp switch and the headlamp drive switch are integrated, and A switch whose switching order is a first state in which the headlamp is off and in an exposed state, a second state in which the headlamp is off and in a concealed state, and a third state in which the headlamp is on and in an exposed state. The above objective has been achieved by providing the following.

is always in contact with the sliding plates 16s and 17s.

The contact T of the lighting switch 23 is connected to the coil L6 of the tail lamp relay 6, and the contact OFF is an open contact that is not connected to anything else.
Although the lighting switch 23 is not shown, the lighting operation lever can be turned to "UP", "OFF",
If you operate the position where “T” and “H” are displayed in that order,
In response to the operation of the lighting operation lever, the grounded contact piece T23c comes into contact with contact UP, contact OFF, contact T, and contact H. However, when the operating lever is in the "H" position, the contact piece T23c contacts both the contact point T and the contact point H.

The contacts HU and HF1 of the daylight switch 24 for switching between high beam and low beam of the headlamp and passing operation are connected to the coil L12 of the daylight relay 12, and the contact HF2 is connected to the diode D7 and the diode D8 of the light retractor relay circuit 9, respectively. ing. contact

When the diode D8 is grounded, a bias voltage is applied to the transistor Tr2, and the transistor Tr2 is turned on. As a result, the transistor
Tr1 turns ON, relay 22 operates, and contact T
22 closes. When the grounding of the diode D8 is released, the ON state of the transistor Tr2 is maintained for a certain period of time (about 2 to 4 seconds) by the charge of the capacitor C3, so that the contact T2 is closed.
2 opens after a certain period of time has passed.

Next, the effect will be explained. First, when the lighting control lever is in the "OFF" position and the dimming control lever is in the "HL" position as shown in the figure, and the headlamps 14 and 15 are hidden, the fusible link 4 → coil In the first loop circuit consisting of L8 → diode D5 → contact UP → ground, contact UP is open, and fusible link 4 → coil L8 → diode D6 →
Since the contact H of the second loop circuit consisting of contact H→earth is open, the first and second loop circuits are each in a cutoff state. Furthermore, since the contacts T18d and T19d of the retractor switches 18 and 19 are in contact with the insulating parts 18i and 19i, the retractor motors M1 and M2 do not operate.

Next, when the lighting operation lever is set to the "UP" position, the contact UP is grounded, so the first
The loop circuit becomes energized, and the common contact T8c of the light retractor relay 8 is switched to the contact T8u side. As a result, retractor switch 1

When contacting s, 19s, brake relay 20, 2
Since the coils L20 and L21 of No. 1 become non-conductive, the driving of the retractor motors M1 and M2 is stopped. At this time, the headlamps 14 and 15 are completely exposed. Also light switch 16, 17
The contacts T16a and T17a are the sliding plates 16s and 17
However, since the contact H of the lighting switch 23 is released, the headlamp 14,1
5 does not light up.

Next, when the lighting control lever is set to the “OFF” position, the contact UP will be released from the ground.
The circuit of the first loop is de-energized, and the contact T8c is switched to the contact T8d side. As a result, the down contact T18d and the common contact T18c, and the down contact T19d and the common contact T19c are respectively energized, the retractor motors M1 and M2 are started, and the headlamps 14 and 15 are driven to conceal. As the down contacts T18d and T19d come into contact with the insulating parts 18i1 and 19i1, respectively, due to the rotational drive of the retractor motors M1 and M2, the drive of the retractor motors M1 and M2 is stopped, and the head lamps 14 and 15 are completely hidden. At this time,
Contacts T16a and T1 of light switches 16 and 17
7a contacts insulating parts 16i and 17i.

Next, when the lighting operation lever is moved to the "T" position, the contact point T is grounded. As a result, the tail lamp relay 6 is activated and the tail lamp 11 is turned on. At this time, the headlamps 14 and 15 remain hidden.

Next, when the lighting operation lever is set to the "H" position, the contacts T and H are grounded, so that the tail lamp 11 is maintained in a lit state. Furthermore, by grounding the contact H, the circuit of the second loop becomes energized, and the contact T8c switches to the contact T8u side, so the retractor motor M
1 and M2 are driven, and the headlamps 14 and 15 are exposed. Further, since the contacts T16a and 17a of the light switches 16 and 17 come into contact with the sliding plates 16s and 17s, the headlamp relay 7 is activated and the low beam headlamps 14 ₁ and 15 ₁ of the headlamps 14 and 15 are turned on. In this state, if the dimmer operating lever is set to the "HU" position, the high beam headlamps 14u and 15u are turned on. Further, when the dimmer operating lever is operated back and forth between the "HL" and "HF" positions, the low beam headlamps 14 ₁ and 15 ₁ and the high beam headlamps 14u and 15u flash alternately in accordance with the operation.

When the lighting operation lever is returned to the "T" position, contact H is released from the ground, so contact T8c
is switched to the contact T8d side. As a result, down contact T18d, common contact T18c, down contact T
19d and the common contact T19c are respectively energized, the retractor motors M1 and M2 are started by the same action as when the operating lever is returned from the "UP" position to the "OFF" position, and the headlamps 14 and 15 are hidden. Driven. Also, since the contacts T16a and T17a of the light switches 16 and 17 contact the insulating parts 16i and 17i, the headlamp 14
₁ , 15 ₁ goes out.

Furthermore, turn the lighting control lever “OFF”
When it is returned to the position, the grounding of contact T is released, so
The tail lamp 11 goes out.

Next, when the lighting control lever is in the "OFF" position, when the daimer control lever is set to the "HF" position, the diode D8 of the light retractor control relay circuit 9 is grounded, and the contact T22 is grounded.
will close, so turn the lighting control lever “UP”
The retractor motors M1 and M2 are started by the same action as when the retractor motors are in the position, and the headlamps 14 and 1 are activated.
5 is driven to expose the retractors M1 and M2, and the driving of the retractors M1 and M2 is stopped with the headlamps 14 and 15 completely exposed. At this time, the contact HF1 of the daylight switch 24 is also grounded, so the headlamp 1
4,15 high beam headlamp 14u,
15u lights up.

The head lamps 14u and 15u are lit while the daylight operation lever is in the "HF" position. Furthermore, even if the demagnet operating lever is in the "HF" position after the drive of the retractor motors M1 and M2 is stopped, the contact T8c has been switched to the contact T8u side, so the retractor motors M1 and M2 are driven in concealment mode. It will not be done. Also, even if the deima control lever is returned from the "HF" to the "HL" position, contact T22 remains closed for a certain period of time, so if the deima control lever is operated back and forth between the "HL" and "HF" positions within this time, The high beam headlamps 14u and 15u of the headlamps 14 and 15 blink.

When a certain period of time has elapsed after the passing operation is completed (when the daylight operation lever returns from the "HF" position to the "HL" position), contact T22 opens and contact T
8c switches to the contact T8d side, the retractor motors M1 and M2 are started by the same action as when the lighting operation lever changes from the "UP" position to the "OFF" position, and the headlamps 14, 1
5 is driven to conceal.

According to the device of the above embodiment, the lighting operation lever can be used to switch between OFF, lighting only the tail lamp (headlamp concealment), and turning on the tail lamp and headlamp (headlamp exposure) in exactly the same way as a constantly exposed type headlamp. When you turn the lighting control lever in the opposite direction from OFF, you can turn off the lights and expose the headlights. In addition, since passing can be performed at any time using the dimmer operating lever, and the exposure of the headlamp is maintained for a set time after the last passing, continuous passing can be carried out smoothly.

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 according to the present invention is used, the headlamp can be turned on, turned off, and concealed exposure drive can be performed with one operating lever, so it is easy to operate, and the headlamp can be hidden and exposed. Since only the driving operation can be performed, it has the excellent effect of allowing the headlamp to be exposed without turning it on. Another advantage is that this operation can be performed in exactly the same order as conventional operations.
