Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a retractable headlamp device for an automobile.

BACKGROUND OF THE INVENTION Recently, retractable headlamps have been increasingly used in passenger-type automobiles due to vehicle body design, and one example of such a retractable headlamp is a so-called exposed type.

As shown in FIG. 4, for example, this exposed type retractable headlamp device includes a headlamp 2 rotatably supported on the front body 1 of an automobile, and a headlamp 2 supported tiltably. In addition, a support member 6 rotated by a motor 5 via a motor link 3 and a link rod 4, a stopper mechanism 7 for maintaining the upright position of the headlamp 2 when it is turned on, and a stopper mechanism 7 provided between the headlamp 2 and the support member 6, It mainly consists of an optical axis adjusting screw and the like that adjusts and determines the optical axis of the lamp 2 relative to the support member 6.
When the headlamp 2 is turned on, the headlamp 2 rotates and stands up from inside the front body 1 via the support member 6 and the stopper mechanism 7, as shown in the figure, while when the headlamp 2 is turned off, it rotates due to the reverse action. The lens 2a surface of the lamp 2 is stored supine within the front body 1 (see Japanese Utility Model Publication No. 170337/1983).

Problems to be Solved by the Invention However, in the conventional device described above, if the position of the lamp 2 when standing is set so as to obtain a normal optical axis, the lens 2a surface of the lamp 2 when retracted and the outer surface of the vehicle body A step occurs between 1a. That is, since the headlamp 2 relative to the support member 6 is fixed via the optical axis adjustment screw at a position where the normal optical axis is obtained when the support member 6 is in the upright position, even if the normal optical axis is obtained when the lamp 2 is upright in the design. Even if the setting satisfies both the position where the lens 2a of the lamp 2 is flush with the outer surface 1a of the vehicle body when stored, there may be errors in parts and assembly during the manufacturing process, variations in load distribution, etc. Therefore, when the support member 6 is rotated to the retracted position after adjusting the optical axis of the lamp 2, there is a problem that the lens 2a surface of the lamp 2 is not flush with the outer surface 1a of the vehicle body, resulting in a step. . If such a step occurs, it not only looks bad, but also causes wind noise and noise. Also, if there is a large gap between the front body 1 and the lamp 2, it may cause foreign objects to be caught between the front body 1 and the lamp 2. There is a problem in that contamination can cause malfunctions.

Problems to be Solved by the Invention The present invention was devised in view of the above-mentioned problems of the conventional retractable head lamp device for automobiles. The first to support

The operation of this embodiment will be explained below.

First, the state in which the headlamp 15 is raised from the state shown in FIG. 3 in the vehicle body 11 as shown in FIG. 2 will be explained.
When the motor link 62 is rotated by forward rotation of the first link member 13, the first link member 13 is moved to the third link member by the transmission shaft 63.
Rotating in the direction of the arrow in the figure, the regulating piece 60 of the headlamp 15 separates from the storage stopper 19, and
The rear surface 27 of the first link member 13 presses the front surface 36a of the L-shaped pressing piece 36 of the second link member 16 to rotate the second link member 16 in the same direction. Therefore, the lamp frame 14 and headlamp 15 are simultaneously rotated in the upright direction via the first and second optical axis adjustment screws 29 and 38. And the second link member 16
The contact piece 35 contacts the upright position stopper 18,
When further rotation is restricted, the head lamp 15, whose lower end was biased toward the first link member 13 by the coil spring 58, moves away from the head lamp 15 against the spring pressure. The pressing portions 321 of the link member 16 press against both ends 4 of the support member 44.
41 and 441 to rotate the first optical axis adjustment screw 38 forward together with the support member 44, the headlamp 15 is rotated toward the normal optical axis position in the left and right direction, and the second link member 16 is rotated forward. The 1-link member 13 and the upright position stopper 18 cooperate to support each other with clamping pressure. Therefore, the headlamp 15 is fixed to the support body 12 via the first and second link members 13 and 16 and the first and second optical axis adjustment screws 29 and 38, and the normal optical axis is adjusted as shown in FIG. You will be held upright in position. At the same time, the motor 61 also receives a load and is automatically stopped. The optical axis of the headlamp 15 is adjusted in advance at this position, but if necessary, it can be adjusted vertically and horizontally using the optical axis adjusting screws 29 and 38.

Next, to explain the case where the headlamp 15 is stored in the vehicle body 11 from the above-mentioned upright state, the motor 61 is rotated in the forward direction and the first link member 13 is moved through the motor link 62 and the transmission shaft 63 by the arrow shown in FIG. When rotated in the direction, first, the rear surface 27 of the first link member 13 and the front surface 36a of the L-shaped pressing piece 36
are separated, the clamping pressure between the first link member 13 and the upright position stopper 18 against the second link member 16 is released, and the normal optical axis state of the headlamp 15 is also released. Therefore, the lower part of the headlamp 15 is tilted and biased toward the first link member 13 by the coil spring 58, while the first link member 13 pushes against the lamp frame 14 via the pressing piece 67 provided at the lower front end of the first link member 13. Press the rear lower edge and rotate together with the headlamp 15 in the storage direction. Then, as shown in FIG.
Rotation is regulated by contact with the body 11, and the body 11 is stored and held in a supine state. That is, the head lamp 15
becomes freely tiltable with respect to the first link member 13 at the same time as the first link member 13 rotates in the storage direction,
It can also be tilted freely in the stored position. For this reason,
The above storage position stopper 19 and coil spring 5
If the lens surface 40 is appropriately set in advance so as to be flush with the vehicle body outer surface 70 in relation to the tilting posture due to and vehicle outer surface 7
It is possible to satisfy both requirements of making the surface 0 and 0 the same plane.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes or the like that do not depart from the gist of the present invention are included within the scope of the present invention. . That is, for example, changes in the arrangement position of the coil spring 58, etc. may be made as necessary to ensure that the lens surface 40 and the outer surface 70 of the vehicle body are flush with each other when the lens surface 40 is stored. Good too.

Effects of the Invention According to the retractable headlamp device for an automobile according to the present invention, the first
The headlamp, whose normal optical axis is determined by its relative relationship with the link member, is in a state where it can be tilted freely with respect to the first link member except for the upright position when it is turned on, and the upright position and the vehicle body where the normal optical axis can be obtained. Since the storage position and storage position of the headlamp can be set separately, not only can a normal optical axis be obtained when using the headlamp, but also the lens surface and the outer surface of the vehicle body can be on the same plane when storing the headlamp. As a result, the appearance is good, the appearance value is improved, and car body noise caused by wind noise can be reliably prevented. Furthermore, since there is no gap between the vehicle body and the headlamp, malfunctions due to foreign objects getting caught in the vehicle are avoided.

Moreover, the close relationship between each component makes the operating condition stable and good.
