Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a retractable headlamp device that is provided with a headlamp that can be moved in and out of a body panel at the front of a vehicle.

[Prior Art] The above headlamp device retracts the headlamp into the body panel except when the lamp is on, which reduces air resistance during driving and makes it possible to realize an innovative car style. be.

Traditionally, this type of device has a headlamp that is rotated into the body and stored, but during so-called passing operations in which the headlamp is turned on to signal the vehicle ahead, the headlamp is rotated out of the body. There was a problem that it took time to move forward and face forward, and the response of passing was poor.

Therefore, a device has been proposed that uses a parallel link to move the headlamp forward at all times (Japanese Unexamined Patent Application Publication No. 1983-93637), but if the moving stroke is large, the link rod must be made longer. Therefore, in addition to requiring installation space, the drive mechanism is complicated, and in particular, there are problems in that it has a large number of pivot points and is likely to have looseness in its operation.

[Purpose of invention]

This invention was created in view of the above problems, and it is possible to move the headlamp up and down while maintaining a horizontal position with the headlamp facing forward, and the mechanism is simple and the operation is stable without any play. An object of the present invention is to provide a retractable headlamp device.

[Structure of the idea]

That is, the device of the present invention is provided with an opening on the top surface of the body panel through which the headlamp is moved in and out, and a cover plate is provided with the rear end pivoted to the rear edge of the opening so that it can be rotated upward and opened to hold the headlamp. The headlamp bracket has its front upper end rotatably supported on the lower surface of the front end of the cover plate, and moves in and out of the opening along an arcuate trajectory as the cover plate rotates. The lower part of the bracket is constantly urged rearward and upward by the urging means, and an arcuate cam surface is provided at the rear of the bracket to abut the rear end of the lower part of the bracket, thereby holding the headlamp in a horizontal position. The structure will allow entry and exit.

〔Example〕

In FIG. 1, a front fender panel P of a vehicle tilting forward (to the left in the figure) is provided with an opening P1, and within the fender panel P corresponding to the opening P1 is a retractable headlamp device according to the present invention. is provided. The headlamp device includes a support frame 1, a lid receiving plate 2, a lid plate 3, and a lamp bracket 4 for holding a headlamp L.

The support frame 1 is formed into a gate shape as shown in FIG. 3, and is fixed to an unillustrated inner panel at an appropriate location. A motor 5 is attached to a mounting hole 11a provided at the lower end of one leg 11 of the frame 1, and a motor link 52 is attached to the motor shaft 51 so as to protrude in the radial direction. The other leg portion 12 of the pedestal 1 has a front end surface as a cam surface 12a. Cam surface 12a
is an arcuate curved surface that slopes forward and upward, and its upper and lower edges are bent forward and serve as stopper portions.

The lid receiving plate 2 has both side edges bent downward to have a U-shaped cross section as a whole, and a punch hole 21 provided at the rear end is provided at the upper end of the support frame 1 located near the rear edge of the opening P1. The above-mentioned mount 1 is aligned with the punched hole 13 and inserted through both punched holes.
It is rotatably supported on the shaft. In this way, the lid receiving plate 2 can be rotated in the vertical direction as shown by the arrow in FIG. A joint pin 22 (FIG. 3) is erected at the bent portion of the lid receiving plate 2, and one end of the link rod 6 is pivotally connected to the pin 22. The other end of the link rod 6 is connected to the tip of a motor link 52 provided on a motor shaft 51 so as to be relatively rotatable. Furthermore, a spring locking piece 23 is formed on the lid receiving plate 2.

The lid plate 3 has a U-shape with both side edges bent downward in substantially the same shape as the lid receiving plate 2, and the bent portion is fixed to the bent portion of the lid receiving plate 2 with screws. . Therefore, the lid plate 3 and the lid receiving plate 2 are integrally engaged and operate as one. When the headlamp L is housed in the fender panel P, the cover plate 3 forms a continuous surface with the fender panel P as shown in FIG. 1, and covers the opening P1 thereof.

The lamp bracket 4 has a center hole 41 into which the rear part of the head lamp L is inserted and fixedly held. The bracket 4 is rotatably connected with a pin by aligning punch holes 42 provided on both sides of the upper end with punch holes 24 provided on both sides of the front end of the lid receiving plate 2. Further, a cam follower part 43 is formed in the bracket 4 at a position below the hole 42 forming part and projects rearward, and a roller 431 is attached to the tip of the cam follower part 43. The hole 432 provided in the cam follower portion 43 and the locking piece 23 provided in the lid receiving plate 2
A coil spring 7 is stretched between the springs 7 and 7.
The bracket 4 is always urged to rotate rearward and upward by the spring force. The roller 43 is brought into contact with the cam surface 12a of the support frame 1,
It is pressed against the cam surface 12a by the urging force of the spring 7. In this state, the bracket 4 is held in a horizontal position with the headlamp L facing forward.

When the motor 5 is rotated, the motor link 52 rotates in the direction of the arrow in FIG. 1, and as the motor link 52 rotates, the lid receiving plate 2 rotates upward via the link rod 6. . At this time, cover plate 3
rotates upward together with the lid receiving plate 2 to open the opening 3. As the lid receiving plate 2 rotates, the lamp bracket 4, which is pivotally supported at the tip of the lid receiving plate 2, is pulled upward in an arcuate trajectory and is advanced to the outside of the fender panel P, as shown in FIG. During this advancing process, the roller 43 of the cam follower section 43
1 rolls upward while being pressed against the cam surface 12a and guided by the surface 12a. Therefore, the cam surface 12a is an arcuate surface that matches the rotation locus of the pivot point of the headlamp bracket 4, so that the bracket 4 does not change direction, and therefore the headlamp L remains facing forward. Move up and down.

When the headlamp L is housed in the fender panel P, the state shown in FIG. 1 is restored by rotating the motor 5 in the opposite direction from the state shown in FIG.

[Effect of idea]

As described above, according to the retractable headlamp device of the present invention, the headlamp can be moved forward and out of the body panel at all times. It is possible to irradiate the light forward, and it is possible to smoothly perform passing operations that require quick response.

In particular, the lower part of the headlamp bracket 4, which holds the headlamp L whose upper end is pivotally supported by the lid receiving plate 2, is pressed against and guided by the cam surface 12a, which is different from the conventional parallel link mechanism. Since there are fewer pivot points, there is less risk of play, and the headlamp L can move up and down stably while being guided by the cam surface 12a. Furthermore, the assembly structure is simpler than that of a parallel link mechanism.
