Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a headlamp cover, and more particularly to a movable headlamp cover that can be opened and closed depending on whether the headlamp is turned off or turned on.

This type of movable headlamp cover reduces air resistance when the car is running, protects the headlamp,
For the purpose of improving the design of automobiles, it is possible to open and close the headlights depending on whether the headlights are turned off or turned on. However, in recent years, there has been a trend toward designs that lower the front of the bonnet of automobiles in order to reduce air resistance during driving and improve fuel efficiency, making it difficult to secure space to store the headlamp covers. .

The object of the invention is to provide a new and simple headlamp cover which overcomes the above-mentioned drawbacks.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, numeral 10 indicates the body of an automobile, and a headlamp 12 that can be concealed by a cover 11 is attached to the front portion of the body 10 of the automobile. That is, the cover 11 is configured to be opened and closed according to whether the headlamp 12 is turned off or turned on.

In FIG. 3, reference numeral 13 indicates a hollow box-shaped case, and a headlamp 12 is installed inside the case 13.
is stored. Pins 14, 14 are attached to both lower ends of the cover 12, and these pins 14, 1
4 is a cam groove 1 provided on both sides of the front end of the case 13;
5 and 15 are inserted and guided. Reference numerals 16 and 17 indicate lift links whose one ends are pivotally supported on both sides of the upper edge of the cover 12 via pins 18 and 18. The other end of one lift link 16 is connected to the case 13 by a pin 19.
is supported by An oval hole 20 is provided at the other end of the other lift link 17, and an oval portion 22 of a serration pin 21 is fitted into the hole 20. The serration portion 23 of the serration pin 21 meshes with the tooth portion 25 of the pinion 24.
Therefore, the serration pin 21 and the pinion 24 are integrally connected through the hole 26 of the case 13.

Reference numeral 27 indicates a sector gear 27, and a tooth portion 28 formed at one end of the sector gear 27 is connected to the pinion 2.
It is possible to mesh with the tooth portion 29 of No. 4. The sector gear 27 is inserted into the hole 31 of the case 13 using the pin 30.
is supported by A pin 35 is inserted into a hole 32 provided at the other end of the sector gear 27 and a hole 34 provided at one end of the link 33. The other end of the link 33 is pivotally provided to one end of a link 37 by a pin 36, and the other end of the link 37 is functionally connected to a motor 38 serving as a power source.

The operation of the present invention will be described below.

To open the cover 11 as shown in FIG. 5 from the state in which the headlamp 12 is hidden by the cover 11 in FIG. 4, the links 37 and 33 are driven by the motor 38 in FIG. When receiving the driving force, the sector gear 27 rotates counterclockwise about the pin 30 as a fulcrum. When the sector gear 27 rotates counterclockwise, the sector gear 27
The pinion 24 rotates clockwise through the teeth 28 of the pinion 24 and the teeth 29 of the pinion 24. Therefore, the lift link 17 simultaneously rotates clockwise about the serration pin 21, and lifts the pin 14 of the cover 11, which was located at the lower end of the cam groove 15 of the case 13.
is slidably guided in the cam groove 15, and the pin 14 of the cover 11 is positioned at the upper end of the cam groove 15 as shown in FIG. 5, so that the cover 11 is in an open state.

Next, in order to change the state in which the cover 11 is open as shown in FIG. 5 to the state in which the headlamp 12 is hidden by the cover 11 as shown in FIG. 4, the operation described above is reversed.

As described above, in the present invention, the cover is slidably guided by the cam groove provided on the front edge of the case through the sector gear, pinion, and lift link when driven by the power source, so that the cover can be opened and closed. Even if the front part of the bonnet of an automobile is designed to be lowered and the space is small, the cover can be opened and closed with a simple structure, and its practical effects are great. Further, snow, dust, etc. that accumulate on the cover when the cover is opened are discharged to the outside by the cover closing operation, so that the headlamp will not become dirty or become inoperable.
