Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a headlamp exposure mechanism for a cabover type automobile.

(Prior Art and its Problems) An example of a cab-over type automobile in which an engine is mounted under the driver's seat is a one-box car as shown in FIG. The headlamp 1 of a one-box car is usually disposed at the front of the car with its light-emitting surface exposed at all times.
If the retractable headlamp structure is such that the light emitting surface is exposed only when the lamp is turned on, it will be possible to more accurately meet the diversified needs of users. However, in this type of automobile, the mounting surface of the headlamp 1 stands almost vertically, so
There is a problem in that it is difficult to apply the headlamp up/down mechanism normally used in sports cars and the like as is.

(Purpose of the invention) The purpose of this invention is to solve the problems of the prior art described above, and to provide a headlamp with a simple structure that allows the light emitting surface of the headlamp to be exposed freely and in a desired manner in a cabover type automobile. The purpose is to provide an exposure mechanism.

(Means for Achieving the Object) In order to achieve the above object, the headlamp exposure mechanism according to this invention includes a lamp cover that is attached to the front of the headlamp of a cab-over type automobile so that it can be opened and closed, and a lamp cover that can be opened and closed. The opening/closing mechanism includes a drive member having a fulcrum above the headlamp and protruding in front of the headlamp so as to be rotatable in the vertical direction about the fulcrum, and a drive member that protrudes in front of the headlamp, and a cable slidable in the left-right direction along the front side portion, the outer end of the drive member being engaged with the lamp cover and the inner end thereof being linked to the cable, the cable being slidable in the left-right direction; The movement of the lamp causes the drive member to rotate, and the lamp cover is accordingly opened and closed in a rotational manner.

(Embodiment) FIG. 1 is a structural explanatory diagram showing an embodiment in which the headlamp exposure mechanism according to the invention is applied to, for example, the one-box car of FIG. 8. The headlamp 1 is stored in headlamp storage spaces 2 on the left and right sides of the front of the automobile (only the left side is shown in FIG. 1). A cover mounting surface 3 is formed at the upper front position of the headlamp storage space 2, and a lamp cover 4 is mounted on this cover mounting surface 3 so as to be openable and closable. The front side panel 5, center garnish 6, and bumper 7 are mounted and arranged at predetermined positions according to the arrows shown in the figure.

FIG. 2 is an explanatory diagram showing the mounting structure of the lamp cover 4. FIG. As shown in FIG. 2A, the inner surface of the lamp cover 4 has hinges 8a and 8 at the upper left and right ends.
b, and a guide receiver 9 extends vertically between them. On the other hand, as shown in FIG. 1, a mounting plate 10 is disposed approximately at the center of the cover mounting surface 3, and a lamp cover 4 is mounted on the mounting plate 10, as shown in detail in FIG. 2B. It forms an opening and closing mechanism.

This opening/closing mechanism includes a drive member 11 and a cable 1.
2, and a link member 13 that connects the drive member 11 and cable 12. The drive member 11 is fitted into a support member 14 erected on the mounting plate 10, and is rotatably arranged around a fulcrum 16 protruding from a window 15 of the support member 14 and engaged therewith. . The window 15 is formed as an elongated hole in the vertical direction, so that the fulcrum 16 can move up and down when the drive member 11 rotates. A slit window 17 is formed at the lower end of the support member 14 in parallel with the mounting plate 10, and within this slit window 17, one end of the drive member 11 is provided at one end of the link member 13 in the longitudinal direction. The driving member 11 and the link member 13 are connected to each other by being fitted into the slit 18 . The other end of the drive member 11 is arranged to protrude in front of the headlamp 1, and a guide 19 is attached to the tip. Further, the other end of the link member 13 is connected to the cable 1
2 is connected. The drive member 13 is rotatably arranged around a fulcrum 20, and the connecting portion of the cable 12 to the drive member 13 is fixed and extended in a curved manner along the road.

As shown in FIG. 3, the cable 12 includes a fixed outer cable 12a and this outer cable 1.
Inner cable 1 movable in the length direction within 2a
2b, and at the part of the cable 12 curved in an arc shape on the mounting plate 10, the outer cable 12a has an elongated slit-like cut 12c.
is provided, from which the link member 13 is inserted and fixed to the inner cable 12b. Therefore,
When the inner cable 12b slides within the outer cable 12a, the link member 13 rotates around the fulcrum 20 accordingly. At this time, according to the rotation of the link member 13, the drive member 1
1 (the portion where the guide 19 is disposed) rotates in the vertical direction above the headlamp 1. As shown in FIG. 1, the cable 12 has one end fixed to the mounting plate 10 so as to be slidable in the left and right directions along the front side of the vehicle body, and the other end fixed to the mounting surface 21 of the center garnish 6. There, the inner cable 12b is connected to the drive motor 22. The cable 23 is used to drive a right headlamp cover (not shown), and the left and right cables 12 and 23 are simultaneously driven by the motor 22. As the motor 22, for example, a wire traction motor used for opening and closing a sunroof can be used.

In such a configuration, the guide 19 at the tip of the drive member 11
are slidably inserted into the guide receiver 9 of the lamp cover 4, and the hinge receivers 24a, 24b at both ends are erected from the cover mounting surface 3.
The lamp cover 4 is attached to the cover mounting surface 3 by fixing them with screws or the like.

In this state, if the motor 22 is driven to slide the inner cable 12b, the guide 19 at the tip of the drive member 11 will move vertically in accordance with the rotation of the link member 13 about the fulcrum 20.
According to this movement, the lamp cover 4 moves to the hinge 8a,
It opens and closes in a rotational manner around 8b. FIGS. 4 and 5 are explanatory diagrams showing such an opening/closing operation of the lamp cover 4. FIG. 4 and 6 show the lamp cover 4 in a closed state, and FIGS. 5 and 7 show it in an open state. At this time, Figures 4 and 5
As shown in the figure, a stopper 25 for regulating the position in the closed state may be arranged at the lower end of the lamp cover 4.

In the illustrated example, the lamp cover 4 is closed (Fig. 4,
(Fig. 6) corresponds to the OFF or low beam state of the headlamp 1, and open (Figs. 5 and 7) corresponds to the high beam state of the headlamp 1. For example, when the headlamp 1 is OFF, the lamp cover 4 is It may be completely closed to block the entire light emitting surface of the headlamp 1.

Also, the back of the center garnish 6 is an ineffective space that is not generally used, but the
If the cable drive motor 22 is placed here as in the embodiment shown, this space can be used effectively, and there is no need to secure a place for the motor around the headlamp 1, which is advantageous in terms of space. be.

(Effects of the invention) As explained above, according to this invention, since the lamp cover is opened and closed by moving the cable in the left and right directions along the front side of the vehicle body, a relatively small space is required in the longitudinal direction. The light-emitting surface of the headlamp can be easily integrated into the interior of the vehicle, and can be easily applied to vehicles with little space in the longitudinal direction at the front of the vehicle body, such as cab-over type vehicles, such as one-box cars. It is possible to realize a headlamp exposure mechanism with a simple structure that allows exposure in a desired manner.
