DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a retractable headlamp for an automobile, that is, it is stored in the bonnet at the front of the vehicle body when not lit, and protrudes above the bonnet when lit. Regarding improvements to headlamps.

(Conventional problems) Recently, the front bonnet has been set lower in order to improve the aerodynamic characteristics of the car body or improve the styling.
Along with this, automobiles with retractable head lamps have been provided.

However, conventional retractable headlamps are swingably attached to the vehicle body, and when swung upward, they stand up at the irradiation position on the bonnet.
It was configured so that it would be stored in the bonnet when it swung downwards, but with this configuration,
When the lamp is stored in the hood, the irradiation direction is diagonally downward. For this reason, there is a drawback in that it is not possible to turn on the headlights temporarily or intermittently as a signal to the preceding vehicle when passing, for example, on a highway.

To solve the above-mentioned problems in retractable headlamps, for example, Japanese Patent Application Laid-Open No. 57
There is an invention related to an "automobile headlamp" disclosed in Japanese Patent No. -182538. This connects the headlamp 1 to the parallel link mechanism 2 as shown in FIG.
is used to raise and lower the irradiation position (first irradiation position) and storage position (second irradiation position) in parallel. According to this, the illumination direction of the lamp 1 is always maintained forward, and even when the lamp is stored, the front can be illuminated through the illumination hole 3 provided in the front of the vehicle body, and the above-mentioned passing lighting is possible. According to the invention, the irradiation hole 3 is provided on the front of the vehicle body as described above, but providing such an irradiation hole on the front of the vehicle body gives an appearance of being complicated, and the irradiation hole 3 is provided in the front of the vehicle body as described above. Snow enters the bonnet through the holes, adheres to various parts of the bonnet, and causes problems such as freezing and rusting.

(Purpose of the Invention) The present invention solves the above-mentioned problems in a retractable headlamp that allows passing lighting in the retracted position. A lid is provided in front of the position that opens only when the passing light is turned on. The purpose of this is to improve the appearance of the front part of the vehicle body of this type of vehicle, and to prevent the conventional problems caused by snow entering through the irradiation holes.

(Structure of the Invention) The present invention is characterized by having the following structure in order to achieve the above object.

That is, in a retractable headlamp in which the headlamp is raised and lowered between an irradiation position on the bonnet and a storage position below the bonnet with the irradiation direction facing forward, the headlamp in the storage position is placed in front of the entrance/exit of the headlamp in the bonnet. A passing lid that opens and closes the front is provided. This passing lid is opened when a passing signal is issued when the headlamp is in the retracted position, and enables passing lighting of the lamp in the retracted position, and when the lamp is in the irradiation position on the bonnet. , and is configured to be held in a closed position along the bonnet surface when a passing signal is not emitted even in the retracted position.

By the way, according to Utility Model Application Publication No. 57-57135,
An auxiliary cover that can be moved up and down is provided in front of the headlamp cover that opens and closes in conjunction with the rise and fall of the headlamp, and the rear part of this auxiliary cover is rotated and tilted downward in conjunction with the rise of the headlamp cover. A device for a retractable headlamp is disclosed. The auxiliary cover in this invention has a structure similar to the lid for passing in the present invention, but this auxiliary cover is intended to minimize the amount of protrusion when the headlamp is projected to the irradiation position. The purpose is different from the lid for passing according to the invention.

(Effects of the Invention) According to the above-described configuration of the present invention, the front of the headlamp in the retracted position is opened only when the vehicle is turned on, so that there is no unnecessary opening in the front of the vehicle body and the exterior appearance is improved. It is simple and improves the aesthetics of the front of the vehicle.

In other words, it is configured to swing between the open position C shown in FIG. 2 and the closed position D shown in FIG. 3 in conjunction with the vertical movement of the headlamp 11.

In front of the lamp entrance/exit 15a in the bonnet 15, a passing lid 33 is provided so as to be continuous with the front edge of the headlamp lid 31 which is in the closed position D as shown in FIG. The lid 33 is located directly in front of the headlamp 11 in the storage position B. The lid 33 is pivotally connected to the vehicle body on the inside of the front part, and the rear end shown in FIG. The headlamp 11 is swingable between an open position F in which the headlamp 11 swings downward, and in the open position F, the front side of the headlamp 11 is opened to the outside. A solenoid 35 is provided which swings open and close the lid 33 via a link 34. Here, the solenoid 35 operates to open the lid 33 when energized.

Next, referring to FIG. 5, an electric circuit 40 for controlling the lighting, turning off, and passing lighting of the head lamp 11, raising and lowering the lamp 11, opening and closing of the passing lid 33, etc. will be explained.

First, the lighting switch 41 has an OFF contact a, a sidemarker light ON contact b, and a headlamp ON contact c. is the irradiation direction high/low switch 4
3 to the head lamp 11, respectively. Further, the lighting switch 41 is interlocked with a sidemarker light switch 44, and when the contact b or c of the former 41 is closed, the contact b' or c' of the latter 44 is closed and the sidemarker light 45 is energized.

Furthermore, when the headlamp ON contact c of the lighting switch 41 is closed, the contact c'', which is closed at the same time, is connected to the raising contact d of the headlamp up/down direction changeover switch 46, and also to the vehicle marking light switch 4.
OFF contact a' at retract switch 4
7 to the lowering contacts e of the changeover switch 46, and further connected to the coil 48a of the relay 48 through the changeover switch 46. This lifting direction switch 46 is connected to the headlamp 1.
When the lamp 1 is in the irradiation position A shown in FIG. 2, the lowering contact e is closed, and when the lamp is in the storage position B shown in FIG. 3, the lowering contact d is closed. There is. When the coil 48a in the relay 48 is excited, the contacts 48b and 4
8c is closed and the motor 23 for raising and lowering the headlamp
is connected to power. Here, a motor operating pilot lamp 49 is provided in parallel with the motor 23. Further, the retract switch 47 is a manual switch for raising and lowering the headlamp 11 in a non-lit state.

In addition to the above configuration, the electric circuit 40 is provided with an opening/closing circuit 50 for the passing lid 33. This circuit 50 is composed of a transistor 51 whose base is connected to the negative side of the passing switch 42, a limit switch 52 connected in series with the transistor, and a solenoid 35 shown in FIGS. 2 to 4 also connected in series. . The limit switch 52 is arranged as shown in FIGS. 2 and 3, and detects the position of the lower link 20 of the parallel link mechanism 21 that raises and lowers the headlamp 11, and the lower link 20 is positioned upward as shown in FIG. When the headlamp 11 is in the irradiation position A, it is turned OFF, and as shown in FIG.

Next, the operation of the above embodiment will be explained.

Now, assuming that the headlamp 11 is in the storage position B as shown in FIG. 3, and in order to turn on the lamp 11 from this state, the headlamp ON contact c of the lighting switch 41 shown in FIG. 5 is closed. At the same time, the headlamp 11 is turned on in either the high or low illumination direction via the illumination direction switch 43, and at the same time, the contact point of the side marker light switch 44 is turned on.
By closing c', the vehicle width lights 45 are also turned on. At this time, the coil 48a of the relay 48 is energized from the contact c'' of the lighting switch 41 through the lifting contact d of the lifting direction changeover switch 46, so that the contacts 48b and 48c of the relay 48 are closed and the motor is activated. 23 is operated.Therefore, the crank arms 25, the first and second crank arms shown in FIGS.
The parallel link mechanism 21 connects to the second
The headlamp 11 operates in the state shown in the figure, and the headlamp 11 is accordingly raised to the irradiation position A. In conjunction with this, the headlamp prism 31 is opened. Then, when the headlamp 11 rises to the irradiation position A, the lifting contact d of the lifting direction changeover switch 46 opens and the motor 23 is stopped. In this state, as shown in FIG.
A value of 0 turns it off. Therefore, the solenoid 35 is not energized, and the passing lid 33 is kept closed.

Furthermore, when the lighting switch 41 is operated to close the OFF contact a from the state where the headlamp 11 is lit at the irradiation position A as described above, if the passing switch 42 is not turned on, the headlamp 11 is energized. At the same time as the circuit is cut off and the lamp 11 is turned off, the lowering contact e of the elevation direction changeover switch 46 is closed. The coil 48a of the relay 48 is energized via the contact e, and the motor 23 rotates again. This results in
The headlamp 11 is lowered to the storage position B shown in FIG. 3, and at the same time the headlamp lid 31 is closed. At this time, the lid opening/closing circuit 5 for passing
0 limit switch 52 is turned on.

However, when the passing switch 42 is turned on in this state, the head lamp 11 lights up only while it is turned on, and at the same time, the transistor 5 of the passing lid opening/closing circuit 50 is turned on.
1 is ignited and the solenoid 35 is energized. Therefore, the solenoid 35 is actuated and the passing lid 33 is opened as shown in FIG.
As a result, the headlamp 11 in the storage position B
This makes it possible to irradiate the front through the gap X created between the passing lid 33 and the headlamp lid 31. When the passing switch 42 is turned off, the head lamp 11 is turned off and at the same time the transistor 51 is turned off, thereby stopping the energization of the solenoid 35, and the passing lid 33 is closed as shown in FIG. Returned to position E. Here, passing lighting of the head lamp 11 and opening/closing of the passing lid 33 are performed in the same manner when the side marker light ON contact b of the lighting switch 41 is closed.

In this way, it becomes possible to turn on the headlamp 11 in the retracted position B, and when the headlamp 11 is not in the storage position B, there is no unnecessary opening in the front of the vehicle body, as shown in Fig. 3. The front of the car body has a flat and simple shape.
