Description

[Detailed Description of the Invention] Technical Field The present invention relates to a retractable headlamp employed in a vehicle, particularly an automobile.

BACKGROUND OF THE INVENTION Retractable headlamps, in which the headlamp body can be retracted into a vehicle body when the headlamp is not in use, are well known in the art for the purpose of reducing air resistance and improving the appearance of the vehicle.

As illustrated in FIGS. 5a and 5b, a conventional retractable headlamp has a headlamp body 1a and a cover member 8a integrally constructed, and when the headlamp is used, the headlamp body 1a is inserted into the vehicle body opening 7a as shown in FIG. 5a. brought to you. Further, when the headlamp is not in use, the main body 1a and the cover member 8a are integrally driven to rotate in the direction of the arrow by a drive device (not shown) about the fulcrum 4a.
The headlamp body 1a is stored in the vehicle body, and the cover member 8a closes the vehicle body opening 7a (FIG. 5b).
This makes it possible to reduce the air resistance of the vehicle body and improve the aesthetic appearance of the vehicle body.

However, in the above-mentioned conventional retractable headlamp, the cover member 8a rotates together with the headlamp body 1a, so when the main body 1a is in the use position, the cover member 8a also protrudes outward. Therefore, the cover member 8a not only impairs the appearance of the vehicle, but also increases air resistance when the vehicle is running.

In view of the above, the present applicant has developed a retractable headlamp that allows the headlamp body to be stored from the use position to a storage position at the rear of the vehicle body, and in which the cover member can be stored at the rear side of the vehicle body when the headlamp body is brought to the use position. (Utility Application No. 59-157279). According to this structure, the cover member is not exposed to the outside when the headlamp body is used, so that the above-mentioned drawbacks can be eliminated.
However, in addition to the space for storing the headlamp body, another space is required for storing the cover member, so the total space required to install the retractable headlamp becomes considerably large.

Purpose The purpose of the present invention is to provide a retractable headlamp that eliminates the above-mentioned conventional drawbacks and can reduce the installation space.

Configuration In order to achieve the above object, the present invention pivots the headlamp body to the vehicle body so that the lamp body can be rotated between a use position in the vehicle body opening and a storage position tilted further rearward. a cover member that supports the headlamp body and closes the vehicle body opening when the headlamp body is in the retracted position;
One end of the drive link is pivotally connected to a crank arm that is rotatably driven by a drive device, and the other end of the link is pivotally connected to a portion of the headlamp body other than the part of the headlamp body that is pivotally connected to the vehicle body. The other end of the regulation link, which is pivotally supported on the vehicle body, is pivotally connected to a portion of the cover member on the distal side of the pivoting portion of the cover member to the headlamp body, so that the headlamp body can be rotated from the storage position to the use position. A retractable headlamp is proposed, in which the cover member is configured to rotate forward from a position where it closes the opening of the vehicle body to a position where it is accommodated in the lower region of the headlamp body.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows one of the retractable headlamps installed at the front of an automobile. 1
1 is a headlamp main body, a lamp (light source) not shown is housed in a case 2 of the main body 1, and a glass 3 is fitted and fixed to the front opening of the case 2. FIG. 1 shows the headlamp body 1 in its use position, with the glass 3 facing toward the front of the vehicle.

2 to 4 are explanatory diagrams showing the operating states of the headlamp body 1. In FIG. 2, the headlamp body 1 is in the retracted position, and in FIG. 4, the headlamp body 1 is in the retracted position. When in use position,
FIG. 3 shows the main body 1 in an intermediate position between the use position and the storage position.

In FIGS. 1 to 4, a headlamp body 1 has its lower front portion connected to a vehicle body 5 by a pair of support shafts 4.
The operating position (Fig. 4) is located in the vehicle body opening 7 divided by the hood 6 of the vehicle body 5, and the storage position (second position) is tilted toward the rear of the vehicle body.
(Figure).

Reference numeral 8 denotes a cover member that closes the vehicle body opening 7 when the headlamp body 1 is placed in the storage position.
The illustrated cover member 8 has a cover body 9 that actually closes the opening 7 and a pair of arms 10, 10a integrally connected to both ends of the cover body 9.
0 and 10a are pivot pins 11 located on the same axis,
The headlamp body 1 is pivotally connected to both side walls of the headlamp body 1 via 11a. As a result, the cover member 8 also rotates between the pins 11 and 11a in FIGS. 2 and 4.
It can be rotated between the positions shown in the figures.

A drive device consisting of a motor 12 is supported on the vehicle body 5, and one end of a crank arm 14 is fixed to the rotating shaft 13 of the drive device. A drive link 16 is connected to the other end of the crank arm 14 by a pin 15.
One end of the link 16 is pivotally connected, and the other end of the link 16 is pivotally connected via another pin 17 to a portion of the headlamp body other than the aforementioned support shaft 4 (in the illustrated example, the side wall portion of the body 1).

Further, one end of a regulation link 19 is pivotally supported on the vehicle body 5 via a support pin 18, and the other end of this ring 19 is pivotally attached to the arm 10 of the cover member 8 via another pin 20. Regulatory link 19 and arm 1
The pin 20 for pivotally connecting the head lamp body 1 is provided at a position closer to the distal end of the cover member, that is, closer to the cover member 9 than the position of the pivot joint (pivot pin 11) between the arm 10 and the headlamp body 1.

In the state shown in FIG. 2, the headlamp body 1 is in the storage position and the cover member 9 closes the opening 7, but at this time, the outer surface of the cover member 9 extends substantially continuously with the outer surface of the hood 6. Therefore, by driving a car in this condition, air resistance can be reduced and the beauty of the car body can be improved.

In order to bring the headlamp body 1 to the use position, the motor 12 is operated and the rotating shaft 13 and crank arm 14 are rotated approximately 180 degrees clockwise in FIG. 2. This action causes the pin 15 at the end of the crank arm to move to the second position around the rotating shaft 13.
It rotates clockwise from the position shown by A in the figure to the position shown by B, in other words, from the position shown in FIG. 3 to the position shown in FIG. As a result, the drive link 16 is pushed up, and its pin 17 moves from the position shown by C in FIG. 2, through the position shown in FIG. 3, to the position shown by D in FIGS. 2 and 4. In conjunction with this, the headlamp body 1 rotates counterclockwise about the support shaft 4 toward the front of the vehicle body, and is brought to the use position shown in FIG. 4.

When the headlamp main body 1 rotates as described above, the pivot pin 11 connecting the main body 1 and the cover member 8 also rotates together with the main body 1 from the O to F positions. Since the regulating ring 19 is pivotally mounted at the tip of the headlamp, the cover member 8 not only rotates counterclockwise together with the headlamp body 1, but also rotates counterclockwise with respect to the headlamp body 1 around the pivot pin 11. Rotate clockwise. For this purpose, the cover member 8 is moved from the position shown in FIG. 2, through the position shown in FIG. 3, to the area below the headlamp body 1 shown in FIG.
This lower area is the space occupied by the lower part of the headlamp body 1 when it is in the retracted position.

As mentioned above, move the headlamp body 1 to the use position,
That is, when the glass 3 of the main body 1 is brought to a position in the opening 7, the glass 3 of the main body 1 faces forward, as described above in connection with FIG. can. At this time, since the cover member 8 is housed within the vehicle body, air resistance when the vehicle is running can be reduced compared to a case where the cover member 8 is exposed to the outside.

If the motor 12 is reversed or rotated an additional 180 DEG in the same direction, each element will operate in the opposite manner to that previously described and be returned to the position shown in FIG.

The configuration of one retractable headlamp installed at the front of the vehicle body has been explained above.
It goes without saying that the other headlamp can also be constructed in a similar manner.

Effects According to the present invention, the headlamp body and the cover member are separate members, and when the headlamp body is brought to the use position, the cover member can be housed in the vehicle body. Therefore, it is possible to prevent an increase in air resistance and a deterioration in appearance due to the cover member when the vehicle is running. Moreover, the cover member can be pivoted and retracted into the area below the headlamp body, so that the cover member can be accommodated in the space occupied by the headlamp body when it was in the retracted position. can. In other words, it is possible to share the storage space for the headlamp body and the cover member, and it is possible to reduce the total storage space.
