Description

[Detailed explanation of the invention] This invention is stored inside the vehicle body during normal driving.
This invention relates to a retractable headlamp device for a vehicle that can be exposed outside the vehicle body only when illumination is required.

Conventional headlamps for vehicles include fixed types that are fixed to the car body and are always exposed outside the car body.
They are generally classified into retractable headlamps, which are stored inside the vehicle and are exposed outside the vehicle only when illumination is required. The latter type of retractable headlamp has become popular in recent years because it not only reduces resistance during high-speed driving, but also gives the vehicle a novel exterior design. However, in conventional retractable headlamps, when the headlamp is exposed outside the vehicle body, the headlamp is rotated only by the driving force of the motor via a link mechanism, so its operating speed is slow. Also,
If the motor and link mechanism for rotating the headlamp become inoperable, there is no means for exposing the headlamp from the passenger compartment to the outside of the vehicle body. Therefore, if the vehicle ignores the above-mentioned malfunction and drives and approaches a tunnel or the like that requires illumination, the front of the vehicle cannot be illuminated, creating a danger.

The present invention was made in order to eliminate the drawbacks of the prior art, and provides a retractable headlamp device that allows the headlamp to be exposed outside the vehicle body from inside the vehicle even if the headlamp drive device becomes inoperable. The purpose is to provide.

The present invention provides a lamp cover that is pivotally supported on a shaft fixed to a vehicle body, a drive motor that rotates the lamp cover to expose the headlamp outside the vehicle body or to accommodate it within the vehicle body, and a connection between the lamp cover and the drive motor. A retractable headlamp device comprising a link that is wrapped around the shaft, one end of which is latched to the lamp cover, and the other end of which is latched to the vehicle body to apply a biasing force to the lamp cover that exposes the headlamp to the outside of the vehicle body. a coil spring that is engaged with the front part of the lamp cover and pivotally supports one end of the link, one end of which is coupled to the pin and the other end of which is guided into the vehicle interior to engage the lamp cover and the pin. A wire is provided to release the engagement between the lamp cover and the pin, so that when the drive motor becomes inoperable, the engagement between the lamp cover and the pin can be released via the wire, and the headlamp can be exposed outside the vehicle body by the biasing force of the coil spring. It is configured as follows.

A preferred embodiment of the retractable headlamp device according to the present invention will be described in detail with reference to the accompanying drawings.

The drawing is a perspective view of an embodiment of a retractable headlamp device according to the present invention. In the figure,
The shaft 10 passes through a lamp cover 14 of a headlamp 12, and both ends thereof are fixed to the vehicle. The lamp cover 14 is pivotally supported by a shaft 10 and is rotatable about the shaft 10. Further, a coil spring 16 is wound around the shaft 10, and one end of the coil spring 16 is locked to one side 18 of the lamp cover 14, and the other end is locked to the side opposite to the side 18. 20, and is latched to a fixture 22 fixed to the vehicle body, which applies an urging force to the lamp cover 14 that causes the headlamp 12 to rotate clockwise in the figure. Further, a pin 24 is removably engaged with the front part of the side part 20 of the lamp cover 14.
One end of a wire 26 is fixed to the head of this pin 24, the other end of which is led into a vehicle interior (not shown). A knob 28 is attached to the end of the wire 26 on the vehicle interior side, and by pulling this knob 28, the engagement between the lamp cover 14 and the pin 24 can be released. Note that when the lamp cover 14 is disengaged from the pin 24, it is rotated clockwise about the shaft 10 by the biasing force of the coil spring 16. Also, pin 24
The upper end of the link 30 is pivotally supported, and the lower end of the link 30 is attached to a worm wheel 32, which is rotatably attached to a shaft 31 whose both ends are fixed to the vehicle body.
It is pivotally supported by a pin 36 to an arm 34 fixed to. The upper end of the worm 38 that meshes with the worm wheel 32 to form a pair is coupled to a drive motor 40.

The operation of the embodiment configured as described above is as follows.

When the headlamp 12 built into the vehicle body is exposed outside the vehicle body, when the drive motor 40 is rotated clockwise when viewed from the top of the drawing, the worm 38 connected to the drive motor 40 rotates clockwise. The worm wheel 32 engaged with the worm 38 rotates clockwise.
Therefore, as the arm 34 fixed to the worm wheel 32 rotates clockwise, it pushes the link 30 upward. As a result, the lamp cover 14, which is pivotally supported on the shaft 10, receives an upward force from the link 30 via the pin 24, rotates clockwise around the shaft 10, and the headlamp 12 is moved outside the vehicle body. It will be exposed and will be able to illuminate the front of the vehicle. When the lamp cover 14 rotates clockwise, the coil spring 16 wound around the shaft 10 applies a biasing force to the lamp cover 14 to rotate it clockwise, as described above. , the operation of rotating the lamp cover 14 in the clockwise direction is performed more easily, and the operation speed is also increased. And lamp cover 1
When the headlamp 12 cannot be exposed to the outside of the vehicle body because the link 30, worm gear device, drive motor 42, etc. that rotate the headlamp 4 become inoperable, the headlamp 12 can be removed from the lamp cover via the wire 26 by pulling the knob 28 inside the vehicle. 14 and the pin 24 are disengaged. Thereby, the lamp cover 14 is rotated clockwise about the shaft 10 by the biasing force of the coil spring 16 described above, and the headlamp 12 can be exposed to the outside of the vehicle body. Therefore, with a simple structure, the operation of exposing the headlamp 12 to the outside of the vehicle body, which conventionally required stopping the vehicle and performing it from the outside, can be performed from inside the vehicle, making the operation safe and easy. . Note that when storing the headlamp 12 inside the vehicle body, the drive motor 4
0 counterclockwise, pull the link 30 downward via the worm 38, worm wheel 32, and arm 34, and rotate the lamp cover 14 counterclockwise about the shaft 10.

As described above, according to the present invention, a coil spring is provided that applies a biasing force sufficient to expose the headlamp to the outside of the vehicle body, and a link that rotates the lamp cover and exposes the headlamp to the outside of the vehicle body is rotated. By guiding the wire into the vehicle interior that can release the engagement between the freely attached pin and the lamp cover, the headlamp can be easily exposed to the outside of the vehicle body from within the vehicle interior even if the link or drive motor becomes inoperable. can be done.
