Description

[Detailed description of the invention] This invention covers the headlamp when it is not in use.
The present invention relates to a headlamp cover device for a vehicle, which is equipped with an opening/closing cover that closes when the headlamp is in use and opens to expose the headlamp when the headlamp is used.

It is well known that the above-described headlamp cover device is attached to a vehicle mainly for the purpose of improving the appearance of the vehicle, and various types of headlamp cover devices have been known.

One of the known methods is to provide an opening/closing cover integrally with the headlamp and opening/closing the opening/closing cover to open and close the headlamp itself.In this type of device, when the headlamp is used, Since they protrude from the vehicle body, they inevitably have the disadvantage of increasing air resistance when the vehicle is running.

Another known headlamp cover device is one in which the headlamp is immovably fixed to the vehicle body, and only the cover can be opened and closed.

However, with this type of device, it is necessary to store the opening/closing cover in the vehicle body in order to expose the headlamp when the headlamp is used, and this is a serious problem in that the stored opening/closing cover occupies a large space. There was a drawback.

In other words, if the storage space for the opening/closing cover is large, it becomes difficult to arrange other elements adjacent to the opening/closing cover at desired positions, and the degree of freedom in designing the vehicle body is greatly restricted. .

In order to eliminate this drawback, it is advantageous to adopt a configuration in which the open/close cover is constructed from two cover members, and the storage space for each cover member is reduced.

However, if a link mechanism consisting of rod-shaped or bar-shaped links is used as the driving means for opening and closing each cover member, as is done in conventional devices of this kind, the disadvantage of complicating the structure can be avoided. do not have.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks, to provide a headlamp cover device that can reduce the storage space for the opening/closing cover, and has a simplified configuration.

Hereinafter, referring to the drawings, an example of a structure in which a cover member is actuated by a link mechanism consisting of a rod-shaped or bar-shaped link will be explained first, and then an advantageous embodiment according to the present invention will be explained.

As shown in FIG. 1, a headlamp 2 is fixed to the front part of the vehicle body 1. When in use, this lamp 2 is exposed as shown in FIG. 1, and when not in use, the headlamp 2 is exposed as shown in FIG. It is covered by the opening/closing cover 3 of the lamp cover device.

Figure 3 is a cross-sectional view taken along the line ■-■ in Figure 2;
The figure is a perspective view thereof.

The opening/closing cover 3 that can be pressed on the headlamp cover device described above by pressing the button in FIG. 3 is composed of two members: a first cover member 4 and a second cover member 5. can occupy a closed position, shown in solid lines in FIG. 3, and an open position, shown in dashed lines.

When these cover members 4 and 5 are in the closed position, these members 4 and 5 are located in the opening formed in the vehicle body 1 and close this opening, so that the cover members 4 and 5 are placed inside the vehicle body as described above. Lamp provided2. (Figure 2)
(On the other hand, when the cover members 4, 5 are in the open position, the lamp 2 is exposed (FIG. 1).

As shown in FIGS. 3 and 4, an arm 6 is fixedly attached to one end of the first cover member 4, and is bent toward the inside of the vehicle body and is bent into an approximately "<" shape. , this arm 6 is rotatably supported on the vehicle body 1 by a support shaft 7.

Moreover, one end of a drive link 8 is pivotally attached to the arm portion between the support shaft 7 and the first cover member 4, and the other end of the link 8 is connected to a crank 9 formed in a disc shape with a pin 10. It is pivoted by.

A shaft 11 that fixedly supports the crank 9 is rotationally driven by an electric motor (not shown).

On the other hand, a flange 1 protruding from one end of the second cover member 5
A long hole 13 is formed in 2, and a roller 15 supported at one end of a rotation link 14 is rotatably fitted into this long hole 13.

This rotation link 14 is rotatably supported by the vehicle body 1 by a pivot shaft 16.

A slot 17 extending in the longitudinal direction is formed at the other end of the rotation link 14, and a roller 18 supported at the tip of the arm 6 described above is rotatably fitted into the slot 17. are doing.

The second cover member 5 is pivotally attached to the vehicle body 1 by a support shaft 19 located at its lower end.

When the headlamp 2 is not in use, the first and second cover members 4, 5 are in the closed position shown in solid lines in FIG. 3 and cover the lamp 2, as described above.

When using the lamp 2, the electric motor described above is activated by turning on a switch (not shown).

As a result, the crank 9 is rotated clockwise as shown in FIG. 2, rotated 180 degrees, and then stopped.

As a result of this operation, the pin 10 rotates from the position shown by the solid line to the position shown by the chain line, so that the arm 6 is rotated clockwise around the housing of the support shaft I by the drive link 8, and reaches the position shown by the chain line.

Due to this rotation of the arm 6, the first cover member 4 also reaches the open position shown by the chain line.

At this time, since the first cover member moves in an arcuate trajectory X, the cover member 4 does not interfere with the headlamp 2.

On the other hand, as the arm 6 rotates as described above, the rotation link 14 connected to the arm 6 via the roller 18 and the slot 17 rotates counterclockwise about the housing of the pivot shaft 16.

Accordingly, the second cover member 5 is also rotated clockwise about one portion of its support shaft 19, and reaches the open position shown by the chain line in FIG.

As described above, the first cover member 4 and the second cover member 5 are
Both reach their open positions, and the aforementioned opening formed in the vehicle body 1 is thus opened, so that the lamp 2 can illuminate the outside of the vehicle body without any hindrance (see FIG. 1).

According to the above configuration, the opening/closing cover 3 has two cover members 4
, 5, and these cover members 4.5 can be rotated separately and stored in separate open positions when the lamp 2 is used, so that there is no storage space for each cover member 4, 5. can be made significantly smaller than the storage space of a conventional open/close cover made of one member.

Therefore, the various elements adjacent to the cover member 4.5 can be arranged much more freely than before, and the degree of freedom in designing the vehicle body can be greatly increased.

However, as described above, if a link mechanism consisting of rod-shaped or bar-shaped links is used as a means for operating each cover member as in the above-mentioned configuration, the configuration must become complicated.

FIG. 5 is a sectional view similar to FIG. 3 showing an embodiment of the present invention.

In this embodiment, the mechanism for operating each cover member 4, 5 includes two rollers 20, 21 and two rollers 20, 21.
0 and 21, and a belt 22 wound around the belts 0 and 21.

In this example, a large number of protruding pins 23 are provided on the circumferential surfaces of the two rollers 20 and 21 at equal pitches.
3 is fitted with a hole (not shown) drilled in the belt 22.

The first cover member 4 and the second cover member 5 are connected to each roller 20, 21 via a connecting member 24,25, respectively.

When the headlamp (not shown in Fig. 5) is not in use, each cover member 4, 5 occupies the position shown by the solid line in Fig. 5 and covers the lamp (Fig. 2).Let's use the lamp. In this case, the roller 20 or 21 is rotated clockwise by an electric motor (not shown), and the belt 22 is driven in the direction shown by the arrow.

As a result, the cover member 4, which had occupied the closed position shown by the solid line,
.

In this case, the double-force cover members that operate between the closed position and the open position rotate in the same direction around the axes of the rollers 20 and 21 as the belt 22 operates, so that each cover member The lamp can be operated in a closed position where the lamp is closed and an open position where the lamp is exposed without any problem.

Naturally, a toothed roller and a timing belt may be used instead of the perforated belt 22 and the pinned fi loaf 20, 21.

Further, although one headlamp and its cover device are shown in the drawings, the cover device for the other headlamp can be constructed in exactly the same manner.

In this case, it is also possible to configure the cover members that are buttoned on both cover devices to be operated by a common actuating means.

According to the present invention, the opening/closing cover is composed of two cover members, and these members are operated by a belt and a roller, so that the storage space for the opening/closing cover can be kept small and the structure can be simplified. It has become possible.
