Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cover for a headlamp of an automobile, and more particularly to an opening/closing mechanism thereof.

Recently, measures have been taken to reduce air resistance by attaching retractable covers to automobile headlights and closing the covers while driving, as well as improving the aesthetic appearance of the design and preventing the headlights from getting dirty. It is being

In order to achieve the above purpose, the present invention divides the entire cover into a rectangular upper half cover and a lower half cover, and the upper half cover is pivotably attached to the frame around the hinge axis along the upper edge. However, the lower half cover is configured to be able to change its inclination angle while shifting vertically along the guide groove between the upper closed position and the lower standby position. The upper half cover and the lower half cover cooperate to block and close the headlight in the closed position, and when the door is opened, the upper half cover pivots upward and the lower half cover pivots downward. While deflecting, it changes its inclination angle and sinks into the body. The pivoting of the upper half cover around the hinge axis and the deflection and tilting of the lower half cover are performed in conjunction with an elevating member consisting of a bar and a protruding arm that are threaded onto the rotary feed screw shaft and reciprocate.

The present invention provides a cover opening/closing mechanism that operates smoothly with a simple mechanism, can reliably maintain the opening/closing position, and can improve design and save occupied space. The main idea will be explained below with reference to the figures.

In Fig. 1, 1 indicates a headlamp, and 16
17 indicates an upper half cover and 17 indicates a lower half cover. 4
5 indicates a hender mirror, and 5 indicates a bumper. In FIG. 2, 6 indicates a frame, 7 and 8 side plates, 9 and 10 guide grooves, 11 a top plate, 12 a bottom plate, 13 a window, and 14 a front edge. window 1
3, the headlamp 1 is exposed. There is an elongated gap 15 (FIG. 3) between the front edge 14 and the bottom plate 12.

In the lower part of FIG. 2, 16 indicates an upper half cover, and 17 indicates a lower half cover. Reference numerals 18 and 19 are levers that protrude rearward along both sides of the upper half cover. Each lever 18, 19 is connected to opposite ends of a lower bar 22 by a link 20, 21. 23 is a protruding arm that protrudes from the center of the bar 22 at right angles thereto. As shown in FIG. 3, the tip of the protruding arm 23 is
It is pivotally attached to an arbor 24 on the back side of the lower half cover 17. A boss portion 25 is provided at the center of the bar 22, and this boss portion 25 is screwed into a feed screw 26. Feed screw 2
6 projects upward from the drive device 27 and connects the electric motor 2
9. 28 is a bracket for attaching the drive device to the automobile body.

Returning to FIG. 2, the protruding pins 30 and 31 at the upper ends of the upper half cover 16 fit into the holes 32 and 33 on both upper sides of the frame 6 and serve as hinge shafts to open and close the upper half cover 16. The lower half cover 17 has projecting pins 34 and 35 at the upper ends of both sides slidably fitted into the guide grooves 9 and 10 of the side plates 7 and 8 of the frame 6.

Next, the operation will be explained. In the closed state shown in FIG. 3, the upper half cover 16 and the lower half cover 17 are closed as shown and shield the headlamp 1. When the shaft 26 of the drive device 27 is rotated in this state, the boss portion 25 of the bar 22 that is screwed thereto is lowered. As a result, the upper half cover 16 is rotated clockwise through the link 21 about the axes of the pins 30 and 31 on both sides, and assumes the open position shown in FIG. At the same time, lower half cover 1
7 is pulled down from the boss portion 25 via the protruding arm 23. Therefore, the protruding pins 34 on both sides
35 into the guide grooves 9, 10, the inclination angle is gradually changed, and the lower half cover 17 descends within the gap 15 of the frame until it occupies the position shown in FIG. FIG. 1 shows this door open state.

When the drive shaft 26 is rotated in the opposite direction, the state shown in FIG. 4 returns to the state shown in FIG. 3.

Note that returning to FIG. 2, both links 20 and 21 are located outside the frame 6. Therefore, the length of the lower bar 22 and the length of the upper connecting pins 36, 37 of both the links 20, 21 are determined so as to protrude outward from the surfaces of the side plates 7, 8 of the frame 6.

As explained above, the cover opening/closing mechanism of the present invention operates easily using the link mechanism and the feed screw mechanism, and also ensures the locking action of the screw mechanism in both the open and closed positions. In addition to solving the problem of occupied space, the headlamp can be made smaller and completely closed off.
