Description

[Detailed Description of the Invention] The present invention relates to a headlamp device attached to an automobile.

Conventionally, in order to reduce air resistance while driving a car, when the headlamp is not in use, the headlamp is stored inside the car body using a retractable device, and the upper surface of the front of the car body is made flat, but this conventional method In this case, a link mechanism or the like must be provided to move the lamp up and down, resulting in a complicated structure, and a space is required to accommodate the lamp within the vehicle body.

The present invention fixes the lamp and moves the cover covering the lamp, instead of the tractor-pull structure in which the lamp moves up and down, improving the reliability of lamp operation and the appearance.

The drawing shows an embodiment of the headlamp according to the present invention, and in the drawing, 1 indicates a vehicle body, and 2 indicates a headlamp, and the headlamp 2 extends in the longitudinal direction of the front upper surface of the vehicle body 1, and In accordance with the shape of the vehicle body, the front end is formed to be lower than the rear end, and is attached to the rear end of the concave portion 1'.

A concave guide groove 3 extends in the front-rear direction of the vehicle body on the inner side walls 29, 29 of both sides of the concave strip 1', and the guide groove 3 is aligned with the concave strip 1' and extends forward and downward. is formed into υ.

A cover 4 is provided on the grooved portion 1' so as to face the grooved portion 1' and cover the upper surface of the grooved portion 1'. , and has openings 22, 23 at the front and rear.

An engagement leg 5 for sliding the guide groove is provided on the front end side of the vertical walls 21, 21, a guide piece 25 extending toward the guide groove 3 is formed on the engagement leg 5, and the guide piece 25 is connected to the guide groove. 3
It is designed to slide inside.

A guide protrusion 6 is formed at the rear of the grooved strip 1', and an inner recessed emboss 12 is provided at the center of the guide protrusion 6 so as to extend in the longitudinal direction of the vehicle body. A concave guide groove γ is provided in the walls 24, 24 that hang down on the left and right sides of the guide protrusion 6 so as to extend in the front-rear direction.

An engagement leg 51 for sliding the guide protrusion is provided on the rear end side of the vertical wall 21.21 of the cover 4, and a guide piece 26 extending toward the guide groove 7 is formed on the engagement leg 5'. A guide piece 26 of the combining leg 5' is provided to slide within the guide groove 1.

In order to slide the cover 4, a rack 8 extending in the front-rear direction is attached to the center of the back surface of the cover 4, and a pinion 9 that meshes with the rack 8 is attached to the embossment 12 of the guide protrusion 6. The pinion 9 is provided so as to protrude from the front O notch 27 of the motor 10, and the pinion 9 is meshed with a shaft 20 fixed to the shaft 11 of the forward/reverse rotation motor 10.

As a result, the pinion 9 is rotated by the drive of the motor 10, and the cover 4 is slid in the front-rear direction via the rack 8.

The embossment 12 provided on the guide protrusion 6 is for storing the rack 8 attached to the cover 4 when the cover 4 slides toward the rear of the vehicle body 1. The embossment 12 is provided in the gap 28 to prevent the rack 8 from interfering with the cover 4. is provided.

In addition, since the headlamp 2 is attached to the rear end of the groove 1' formed on the front edge so that it becomes lower as it goes forward, when the cover 4 slides forward, the headlamp 2 becomes lower as it goes forward. The upper surface of the headlamp 2 is provided at a higher position than the upper surface.

Further, the cover 4 is located on the concave portion 1' when the headlamp 2 is not lit by an electric circuit to be described later, and covers the upper surface of the headlamp 2, and when the headlamp 2 is lit, the cover 4 is positioned on the groove 1'. , is located on the guide protrusion 6, and is configured so that the front part of the headlamp 2 is exposed.

Limit switches 13 and 14 are fixed at the front and rear of the guide groove 3, and are connected to the motor 10 via a relay 15, as shown in the circuit diagram of FIG.

In the same circuit diagram, 16 is a circuit breaker, 117 is a lighting switch, 18 is a battery, and 19 is an intermediate switch.

Next, to explain the lighting of the headlamp 2 and the sliding operation of the cover 4, when the limit switch 13 at the rear end is turned on and the light switch 17 is turned on with the cover 4 covering the headlamp 2, the motor starts. 10 rotates in the normal direction. Due to the rotation of the pinion 9, the cover 4 gradually rises along the guide groove 3 and moves toward the rear of the vehicle body, and at the same time, the headlamp 2 lights up.

The engaging leg 5 at the front end of the cover is the limit switch 13.
When the switch hits , the switch turns OFF, and the limit switch 14 linked therewith turns ON.

When the lighting switch 17 is turned off, the headlamp goes out, the motor reverses, and the cover moves to the front of the vehicle body to cover the headlamp. When the engagement leg 5 of the cover hits the limit switch 14, the switch is turned off, and the limit switch 13 turns on.

Since the present invention has a fixed rung as described above, it does not require a link mechanism compared to a tractor-pull structure that allows the headlamp to move up and down.

Therefore, the structure is simple, there is no need to adjust the optical axis, and the operation is reliable and reliability is improved.

The lamp cover has a structure that slides back and forth, and when the lamp is not in use, it is covered with a cover, giving it a good appearance. The headlamp installed in the groove is located above the front opening of the cover, but when using passing lighting, a wide irradiation range or brightness is not required, so the headlamp is located above the front opening of the cover. The function can be achieved by lighting emitted from the opening in the front.

Therefore, since it is not necessary to slide the cover every time the passing is performed, it is possible to perform the passing instantly.
