Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle lamp suitable for application to a searchlight or the like that is attached to the roof of a vehicle such as an automobile.

[Conventional technology]

BACKGROUND ART Conventionally, auxiliary lights such as fog lamps have been attached to automobiles as necessary to ensure road traffic safety. This lamp is used to provide forward illumination when visibility is poor, such as in dense fog or during heavy rain, and the light color is generally light yellow, which absorbs little light.

[Problem to be solved by the invention]

However, because conventional auxiliary lights of this type are fixed to the vehicle body with bolts, etc., the driver cannot freely change the direction of illumination as needed. There was a problem in that even if it was desired to illuminate the sign, it could not be illuminated sufficiently.

Therefore, the present invention solves the above-mentioned problems,
It is an object of the present invention to provide a vehicular lamp that allows the illumination direction to be freely varied as necessary and allows accurate understanding of road conditions.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a light source disposed in a frame such as a spoiler attached to a vehicle body, and a light source that directs light emitted from the light source toward a lens covering an opening provided in the frame. It is composed of a reflecting mirror that reflects the light and a driving means that tilts and drives the reflecting mirror in a predetermined direction.

[For production]

In the present invention, the reflecting mirror is tilted by the driving means to reflect the light from the light source in a predetermined direction.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

Fig. 1 is a perspective view showing an embodiment of the present invention applied to a searchlight, Fig. 2 is a plan view, and Fig. 3 is an external view f+ of a spoiler (frame body) incorporating a searchlight, and a whistle. Figure 4 is a sectional view of the main part. In these figures, 1 is the vehicle body,
Reference numeral 2 denotes a spoiler installed on the roof of the vehicle body 1, and search lights 3 are disposed near both ends of the interior of the spoiler 2, respectively. .

The spoiler 2 reduces the lift force of the vehicle body 1 during running, and is flat and extends long in the left-right direction, and has an arc-shaped opening 4 formed at the front corner that connects the front surface and the side surface. It is covered by a lens 5 colored pale yellow.

The searchlight 3 includes a light source 7 having a reflector 6, and a reflecting mirror 9 that reflects light 8 emitted from the light source 7 toward the opening 4.

The light source 7 is provided diagonally in front of the reflective mirror 9 at the center of the vehicle body, and illuminates the reflective mirror 9.

The reflecting mirror 9 is fixed to the surface of a flat mirror holder 10 long in the left-right direction, and an end 10a of the mirror holder 10 on the vehicle center side is integrally provided with one end of the horizontal movement 11 so as to be perpendicular to the mirror holder 10. It is rotatably supported in the longitudinal direction (horizontal direction) by a vertical shaft 1H. The horizontal shaft 11 is rotatably supported by a bearing member 13 fixed to the inner bottom surface of the spoiler 2 so that its axis is substantially parallel to the left-right direction of the vehicle body 1, and the other end is supported by a bearing member 13 fixed to the inner bottom surface of the spoiler 2. A transmission mechanism 15 is provided that converts the motion into linear motion in the longitudinal direction of the vehicle body. This transmission mechanism 15 has an upper end connected to the horizontal 111
a rotating lever 16 fitted and fixed to the other end of the rotating lever 11; A screw hole 19 is formed into which the front end of the bracket 2 is screwed.
Worm wheel 21 rotatably supported by
and a worm 23 that is provided integrally with the output shaft 22 of the first drive motor 14 and meshes with the worm wheel 21.
It consists of n. Said 1st. The drive motor 14 is attached to a bracket 24 erected on the inner bottom surface of the spoiler 2 together with the bracket 20 of the worm wheel 21. The connecting pin 17 is provided through the rear end of the threaded rod 1B in the radial direction, and both ends of the connecting pin 17 are connected to the rotating lever 1.
It is held vertically movably by an elongated hole 25 provided in the lower end of the holder 6 in the vertical direction. As shown in FIG. 4, a shaft boss 27 is integrally protruded from the center of both sides of the worm wheel 210, and this shaft boss 2T is inserted into a bearing hole 28 provided at the tip of the bracket 20. Pivotally supported.

A bracket 30 in the shape of an abbreviation is provided at one end of the horizontal shaft 11 and extends toward the rear of the vehicle and whose rear end is bent at a substantially right angle toward the outside of the vehicle. A motor 31 and a worm wheel 33 constituting a transmission mechanism 32 that converts the rotation of the motor 310 into linear motion in the longitudinal direction of the vehicle and transmits it to the reflecting mirror 9 are rotatably disposed via a bracket 34. The worm wheel 33 meshes with a worm 36 that is integrally provided on the output shaft 35 of the second drive motor 31, and has a screw retainer 3 in the center.
A screw hole r (not shown) is formed into which the rear end of the connector 7 is screwed. The front end of the threaded rod 37 is connected to a bracket 38 provided on the back surface of the mirror holder 10 via a vertical connecting pin 39. The upper and lower ends of the connecting bin 39 are inserted into and held by elongated holes 40 provided in the bracket 38 and extending in the left-right direction so as to be movable in the left-right direction. Such a transmission device $32 is similar to the transmission mechanism 15 described above.
It is similar to The first and second drive motors 14
, 31 are rotated forward and backward individually or simultaneously by a four-way switch (not shown) installed near the driver's seat.
As a result, the reflecting mirror 9 is rotated back and forth and left and right.

That is, for example, when the first drive motor 14 is manually rotated in the direction of the arrow in FIG. 1, the worm wheel 21 that meshes with the worm 23 is rotated in the direction of the arrow B. Then,
The threaded rod 18 screwed into the screw hole 19 of the worm wheel 21 moves linearly in the direction of arrow C and rotates the rotating arm 16 in the direction of the arrow, so that the horizontal shaft 11 also rotates in the same direction. to tilt the reflecting mirror 9 backward. On the other hand, when the first drive motor 14 rotates in the direction opposite to the direction of arrow A,
The reflecting mirror 9 is tilted forward (in the direction of arrow E).

Next, when the second drive motor 31 is rotated in the direction of the arrow F, the worm wheel 33 meshing with the worm 36 rotates in the direction of the arrow G and moves the threaded rod 37 linearly backward (in the direction of the arrow H). The mirror 9 is rotated rearward about a vertical axis 12. Conversely, when the second drive motor 31 is rotated in the direction opposite to the direction of the arrow F, the reflective mirror 9 is naturally rotated forward about the vertical axis 12.

In the searchlight 3 having the above-mentioned configuration, the horizontal and vertical angles of the reflecting mirror 9 can be freely set by remote control from the driver's seat. It is possible to illuminate diagonally above the front, etc., and improve safety when driving.

〔Effect of the invention〕

As described above, the vehicle lamp according to the present invention includes a light source disposed in a frame such as a spoiler, and a reflecting mirror that reflects the light from the light source, and the reflecting mirror is tilted by a driving means as necessary. Since it is constructed so that its angle can be set in a wide range, it is possible to illuminate a wide area, and it is suitable for use as an auxiliary light such as a searchlight. In particular, when incorporated into a spoiler, the spoiler can also be used as an auxiliary light such as a search light or fog lamp.
