CONSTITUTION:When a head lamp 11 is lighted as usual, a link mechanism 18 is rockingly moved from a chain line position to a full line one by operation of an unillustrated motor whereby the head lamp 11 is made to go up to the extent of a projecting position upward a bonnet 19 and to light it at the said projecting position. On the other hand, in time of housing the head lamp 11, when a passing command is issued, the head lamp 11 is lighted at the said projecting position, while a solenoid 28 of a holding device 26 is energized with current, and the output rod is retreated backward. If so, engagement between the rod and an engaging member 27 at the side of a lid 21 is set free, and thereby this lid 21 is rockingly moved downward to the extent of the chain line position by dint of a spring 31 so that light of the lamp 11 is lightened frontward. This lid 21 is reset to a closing position again when the link mechanism 18 is rockingly moved upward.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a retractable headlamp for an automobile, that is, a headlamp that is housed in the bonnet at the front of the vehicle body when not lit, and protrudes above the bonnet when turned on. Regarding the improvement of

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

However, conventional retractable headlamps are swingably attached to the vehicle body and are configured to be retracted into the bonnet by swinging downward from a position protruding above the bonnet. Therefore, when the vehicle is stored in the bonnet, the direction of illumination of the lamp is diagonally downward, resulting in so-called passing lighting, in which the headlights are turned on temporarily or intermittently as a signal to the vehicle in front, such as when passing on a highway. The drawback was that it was not possible.

To solve the above-mentioned problems with retractable headlamps, for example,
There is an invention related to an "automobile headlamp" disclosed in Japanese Patent No. 57-182538. This is the first
As shown in the figure, a headlamp 1 is raised and lowered in parallel between an extended position (first irradiation position) and a retracted position (second irradiation position) using a parallel link mechanism 2. According to this, the irradiation direction of the lamp 1 is always kept facing forward, and even when the lamp is stored, the front can be irradiated through the irradiation hole (or slit) 3 provided on the entire surface of the vehicle, and the above-mentioned passing lighting is possible. Become.

However, according to the present invention, since the illumination holes or slits must be provided on the front of the vehicle body as described above, the appearance of the front of the vehicle body gives a complicated impression, and furthermore, the illumination holes or slits do not allow dust etc. A problem arises in which foreign objects enter the vehicle body.
Furthermore, if the irradiation holes or slits are closed with a transparent plate to prevent the intrusion of foreign matter, a problem arises in that when the transparent plate becomes cloudy or dirty, the irradiation light during patching becomes weak.

(Object of the Invention) The present invention is intended to solve the above-mentioned problems in a retractable headlamp that allows passing lighting in the retracted position. A lid is provided in front of the storage position of the lamp, which opens only when the passing light is turned on. This improves the appearance of the front part of the vehicle body of this type of car, and also prevents foreign matter from entering through the irradiation holes and slits, or dirt on the transparent plate when it is provided. The purpose is to solve the problem of weakening of the irradiated light due to

Further, the passing lighting must be performed without any time delay when the command is issued, but the present invention makes it possible to immediately respond to the passing command by quickly opening the lid. purpose.

(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 a protruding position on the bonnet and a retracted position below the bonnet with the irradiation direction facing forward, the front swing shaft is positioned in front of the lamp entrance in the bonnet. At the center is a passing lid that swings up and down to open and close the front of the headlamp in its retracted position.
It includes releasable retaining means for retaining the lid in the closed position and spring means for always biasing the lid in the open direction. The retaining means unlatches the lid when a passing command is issued when the headlamp is in the retracted position, whereby the lid is momentarily opened by the spring means.

The lid is closed at the end of passing lighting by an appropriate closing means such as a separately provided solenoid, or in conjunction with the upward movement of the headlamp.

(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 addition, the conventional problem of foreign matter entering the vehicle body through the irradiation hole or slit, or the problem of weakening the irradiated light due to dirt on the transparent plate when the irradiation hole is closed with a transparent plate, etc., is eliminated. .

Further, according to the present invention, the lid that closes the front side of the headlamp in the retracted position is quickly opened when the headlamp is turned on for passing, so that it is possible to turn on the headlamp immediately in response to a passing command.

(Example) The present invention will be described below based on an example shown in the drawings.

As shown in FIG. 2, the headlamp 11 is attached to a base plate 12, and an upper portion is located between a bracket 13 fixed to the plate 12 and a bracket 15 fixed to the vehicle body frame 14 behind it. Link 16 and lower link 1
7 is interposed. The connection points of the upper link 16 and the lower link 17 with the brackets 13 and 15 at both front and rear ends are arranged to form a parallelogram, and these links 16 and 17 and the brackets 13 and 15 form a parallel link. It constitutes a mechanism 18. When the parallel link mechanism 18 is operated by a motor (not shown), the headlamp 11 is moved toward the bonnet 1 as shown by the solid line.
The vehicle is configured to move up and down while maintaining a forward facing position between a protruding position above the bonnet and a retracted position below the bonnet indicated by a chain line. Further, a headlamp prud 20 is attached to the upper link 16 of the parallel link mechanism 18, which closes the lamp entrance/exit 19a of the bonnet 19 when the headlamp 11 is in the retracted position.

On the other hand, in front of the lamp entrance/exit 19a in the bonnet 19, there is a passing lid 21 so as to be continuous with the front edge of the headlamp lid 20 in the closed position and located directly in front of the headlamp 11 in the retracted position. is provided. This lid 21 is fixed to a T-shaped lid base 22 as shown in FIG.
By being pivotally connected to a bracket 24 fixedly attached to the bracket 24, the rear part can be pivoted up and down about a pivot axis X--X connecting the pivot points a and a, as shown in FIG. The headlamp 11 swings between a position where the front side of the headlamp 11 is closed, shown by a solid line, and a position where the front side of the headlamp 11 is open, shown as a chain line.

Further, the passing lid 21 is disposed between the lid base 22 and the side frame 25 of the vehicle body.
Retaining means 26 are provided for retaining the in the closed position. As shown in FIG. 4, this holding means 26 consists of an engaging member 27 fixed to the side of the lid base 22 and protruding outward, and a solenoid 28 fixed to the frame 25 located on the side thereof. When the lid 21 is in the closed position, the rod 28a of the solenoid 28 engages below the engaging member 27 to hold the lid 21 in the closed position, and when the solenoid 28 is energized, the rod 28a is configured to move backward and disengage from the engagement member 27.

Further, between a bracket 29 fixed to the lower surface of the lid base 22 and a bracket 30 fixed to the lower frame 23 of the vehicle body, there is a spring 31 that always biases the passing lid 21 downward, that is, in the opening direction. When the rod 28a of the solenoid 28 is retracted, the lid 21 is opened by the tensile force of the spring 31. A stopper 32 is provided on the bracket 30 on the side of the lower frame 23, and supports the lid 21 opened by the spring 31 at a predetermined open position. Here, the stopper 32 can adjust the opening position of the lid 21 within a certain range.

Further, the rear end of the lid base 22 is provided with a hook 22a whose tip is bent downward, and the base plate 12 is provided with a hook 12a whose lower end is bent forward. There is. These hooks 12a, 22a engage with each other when the headlamp 11 rises from the retracted position to the protruding position with the passing lid 21 in the lower open position, and as the headlamp 11 rises, the lid 21 is raised. It is made to swing upward against the spring 31 to the closed position.

Note that when the lid 21 swings upward, the engaging member 27 fixed to the lid base 22 engages the solenoid 2.
However, as shown in FIG. 4, the upper surface of the engaging member 27 is an inclined surface 27a, and the rod 28
When the tip of the rod 28a comes into contact with the rod 28a, the rod 28a is moved back along the inclination against the spring built into the solenoid 28, or the engaging member 27 is elastically deformed inward, and the lid 21 is It is designed so that upward swinging is not obstructed.

According to the above configuration, when the headlamp 11 is normally lit, the upper link 16 and the lower link 17 of the parallel link mechanism 18 are respectively swung upward about the connection point with the bracket 15 by a motor (not shown). As a result, the headlamp 11 is raised from the retracted position below the bonnet 19, indicated by the chain line in FIG. 2, to the protruding position above the bonnet, indicated by the solid line, and in this state illuminates the front. Further, when the headlamp 11 is not lit, the upper link 16 and the lower link 17 are respectively swung downward, and the lamp 11 is stored in the storage position within the bonnet 19.

However, when the headlamp 11 is in the retracted position, when a command to turn on the passing light is issued to signal a preceding vehicle, the headlamp 11 is turned on.
is lit in the retracted position, and at the same time, the solenoid 28 of the holding means 26 that holds the passing lid 21 in the closed position is energized. Therefore, the rod 28a of the solenoid 28 moves back from the state shown in FIG.
7 is released, and the lid 21 is swung downward by the tensile force of the spring 31 to a position where it abuts against the stopper 32. As a result, the headlamp 1 in the retracted position as shown in FIG.
The front of the lamp 11 is opened, and the light emitted from the lamp 11 illuminates the front of the vehicle. At this time, the lid 21 is activated by the solenoid 28 according to the passing command.
When the headlamp 11 is activated, it is momentarily opened by the spring 31, and is opened almost simultaneously with the lighting of the headlamp 11. Therefore, passing lighting is performed immediately in response to a command without any time delay.

When the passing command is released, the headlamp 11 is turned off, and the electric circuit is configured so that a motor (not shown) is activated at the same time. Therefore, at the end of passing lighting, the head lamp 11 is raised from the retracted position to the protruding position via the parallel link mechanism 18, and in the middle of this, the hook 12a on the base plate 12, which is raised integrally with the lamp 11, is raised to the lid 21. The lid 21 is engaged with the side hook 22a to swing the lid 21 upward against the spring 31. When the lid 21 is swung to the closed position, a solenoid 28 is placed below the engaging member 27.
The rod 28a is engaged. This holds the lid 21 in the closed position, after which the lamp 1
1 is lowered into the storage position again.

In this state, the head lamp lid 20 opens and closes the lamp entrance/exit 19a of the bonnet 19.
Both the lid 21 and the above-mentioned passing lid 21 are closed, and the front portion of the vehicle body has a flat exterior shape with no openings, etc., as shown in FIG.

Note that the structure for closing the passing lid 21 is not limited to the above structure in which it is linked to the rise of the head lamp 11, and other closing means such as a solenoid may be used.
