Description

[Detailed Description of the Invention] This invention relates to an improvement of a concealed headlamp in which the lens surface of the headlamp is covered with a headlamp cover that can be opened and closed.

Conventionally, a structure in which a headlamp is fixed and a headlamp cover is opened and closed is known from Japanese Utility Model Application No. 56-160140 and the like.

However, in the above structure, since the lens surface of the headlamp is fixed in an upright state, the front nose panel portion becomes high. Additionally, since headlamps are generally set at a predetermined height during design due to the illumination angle, it is impossible to lower the front nose, which inevitably increases air resistance at the front of the car. It was hot.

In order to lower the front nose, a retractable headlamp structure can be used in which the headlamp is always retracted and can be popped out when necessary, but this retractable headlamp type has a complicated structure and is also spacious because the lamp body rotates a lot. This is not preferred because it requires space.

This idea was made by focusing on the above problem, and consists of a headlamp that is rotatably attached to the vehicle body, an arm that is attached to the back of the headlamp cover, and a link member that rotates when driven by a motor. By supporting the connecting portion of the headlamp body with the headlamp body, the headlamp body rotates in conjunction with the opening/closing operation of the headlamp cover.

This invention will be explained below based on an embodiment of the semi-concealed headlamp type shown in FIGS. 1 to 4.

In Figures 1 to 3, there is a headlamp set hole 1 in the shroud panel 1 at the front of the vehicle body.
a is formed. A bracket 2 is welded to the outer side of the headlamp setting hole 1a of the shroud panel 1, and a shroud side panel 3 is welded to the inner side. The headlamp 4 set in the headlamp setting hole 1a has pin members 5 provided at the front lower part on both sides thereof.
6 is rotatably attached to a hole 2a formed in the bracket 2 and a hole 3a formed in the shroud side panel 3, respectively. A headlamp cover 7 that covers the upper lens surface 4a of the headlamp 4 has a reinforcement 8 attached to its back surface, and arms 8a and 8b are integrally attached to the reinforcement 8.
It is formed by cutting a portion of both the left and right sides downward. The arm 8a has a pin member 9 inserted into a hole 2b formed in the bracket 2, and the arm 8b has a pin member 10 inserted into a hole 3b formed in the shroud side panel 3.
Each is rotatably mounted. A hole 8c formed below the center of rotation of this arm 8a
and a hole 12b formed in one end 12a of a link member 12 rotatably attached to the bracket 2 with a pin member 11.
3 and is rotatably supported. Further, a hole 8d formed in the arm 8b below the center of rotation of the arm 8b is inserted into a pin member 14 provided on the headlamp 4 and supported for free rotation. The other end 12c of the link member 12 is connected to a rod 1 of a crank mechanism that converts the rotation of a motor 15 attached to the shroud panel 1 into vertical motion.
6 by a pin member 17. In addition, 18
1 is the front nose panel, and 19 is the bonnet.

Next, the operation of this headlamp device will be explained with reference to FIG.

When the headlamp cover 7 is opened, the motor 15 is rotated and the rod 16 is connected to the other end 1 of the link member 12.
When 2c is pushed up, the other end 12 of the link member 12
a rotates forward and downward about the pin member 11, and one end 12a of this link member 12 is connected to the headlamp 4 by the pin member 13, so that the headlamp 4 is connected to the pin members 5, 6 on both sides. Further, the arm 8a on the lower surface of the headlamp cover 7, which is connected by the pin member 13, rotates forward and upward about the pin member 9, and the headlamp cover 7 opens. .

Next, when the headlamp cover 7 is closed, the motor 15 is rotated and the link member 12 is moved by the rod 16.
When one end 12c is pulled down, the other end 12a of the link member 12 rotates rearward and upward about the pin member 11, and as a result, the head lamp 4
The head lamp cover 7 is tilted backward, and the head lamp cover 7
The arm 8a on the lower surface rotates rearward and downward about the pin member 9, and the headlamp cover closes.
The headlamp is stored in a tilted position.

In the above embodiment, the arm 8a and the link member 12 are directly connected by the pin member 13 provided on the headlamp 4, but as shown in FIG.
is attached to the headlamp 4, one end is attached to the arm 8a and the other end is attached to one end 12a of the link member 12, and the link member 12 and arm 8a are attached to the connecting member 2.
They may be linked indirectly via 0.

The operation of the headlamp device of this second embodiment will be explained with reference to FIG.

First, when the headlamp cover 7 is opened, when the motor 15 is rotated and the rod 16 pushes up one end 12c of the link member 12, the other end 12a of the link member 12 rotates forward and upward about the pin member 11. Since one end 12a of this link member 12 is attached to one end 20a of a connecting member 20 attached to the side wall of the headlamp 4 by a pin member 21, the headlamp 4 rotates about the pin members 5 and 6 on both sides. As it stands up, the arm 8a on the lower surface of the headlamp cover 7, which is attached to the other end 20b of the connecting member 20 by the pin member 22 and indirectly connected to the link member 12, rotates about the pin member 9. The headlamp cover 7 opens by rotating upward to the front side.

Next, when the headlamp cover 7 is closed, the motor 15 is rotated and the rod 16 is used to close the link member 12.
When one end 12c is lowered, the other end 12a of the link member 12 rotates rearward and downward about the pin member 11, and as a result, the headlamp 4 tilts rearward, and the headlamp cover 7 The arm 8a rotates rearward and downward about the pin member 22, the headlamp cover 7 closes, and the headlamp 4 is stored in a rearward tilted state.

In the above embodiments, a semi-concealed headlamp type that covers only the upper part of the lens surface has been described, but the same applies to a fully concealed headlamp type that covers the entire lens surface.

As described above, according to this invention, the connecting portion between the arm of the headlamp cover and the link member is
By supporting the rotatably mounted headlamp at a position behind the center of rotation, the headlamp rotates in conjunction with the opening/closing operation of the headlamp cover, and when the headlamp cover is closed, the headlamp body is moved toward the rear. Since the headlamp cover can be stored in a downwardly tilted manner, the headlamp cover can be lowered, making it possible to lower the front nose panel of the car. Therefore, this headlamp device is highly useful in a structure in which the front nose portion of an automobile is lowered in order to reduce air resistance at the front portion.
