Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a support mechanism for attaching an automobile lamp to an automobile.

[Background of the idea]

FIG. 1 is a front view of an example of a device for supporting an automotive lamp so that the optical axis can be adjusted, and FIG. 2 is a sectional view taken along the line taken from FIG. 1.

The lamp body of this example has a structure in which a light source bulb 2 is provided within a lamp housing 1, and a lens 3 is attached to cover the front opening of the lamp housing 1.

The lamp housing 1 forming the above-mentioned lamp body is supported by a fixing member 4 via pivot means at three points A, B, and C shown in FIG. FIG. 2 shows the pivot means at point A of the three points mentioned above.

In the holding device of this example, when the pivot means at point C is used as a fulcrum and the pivot means at points A and B are driven in a direction perpendicular to the plane of the paper in FIG. 1, the optical axis direction of the lamp body can be adjusted horizontally and vertically. be done.

The pivot means described above is required to be easy to assemble, easy to construct with high precision, and to have excellent durability. However, a support mechanism that can satisfy all of these conditions has not yet been developed.

FIG. 3 is a perspective view showing an example of a known support mechanism. This mechanism (Japanese Utility Model Publication No. 58-42186) has a structure in which a spherical seat 5a provided inside a cylindrical bearing 5 is fitted with a spherical portion 6a of a pivot shaft 6. A groove 5b for fitting is provided. A push-on fixing 7 is press-fitted into this cylindrical bearing 5 to maintain the fitting of the pivot ball portion 6a. 7a is a groove.
The support mechanism of this known example has a structure in which the pivot shaft 6 comes off when a force is applied in the direction opposite to the direction in which the pivot shaft 6 is assembled (downward in FIG. 3), so a push-on fixing 7 is provided to prevent it from coming off. Even if this is done, there is a problem that if excessive force is applied during operation, the pivot shaft 6 may come off due to deformation caused by the push-on fixture or by the split groove 7a.

FIG. 4 is an exploded view of a known example different from the above, and FIG. 5 is an assembled view of the same. This publicly known example (Jikko Sho 57-
53867), a vertical hole 8a is provided in the side wall of the holder 8 so that the holder 8 can be expanded like a hinge as shown in FIG. The structure is such that the holder 8 is inserted into a mounting hole 10a provided in the member to be held 10 while being held. The mechanism of this known example has an excellent retaining force for the pivot shaft because the mounting direction and removal direction of the pivot shaft 9 are the same, but since the holder 8 is configured with the vertically divided hole 8a enlarged, ,
The mold for the spherical catch must be angled by the expanded angle mentioned above. In addition, the spherical catch 8b
There is also a problem in that the rotational torque of the pivot shaft 9 varies widely because the manufacturing error and the machining error of the mounting hole 10a are added together and affect the fitting state between the head 9a and the spherical seat 8b.

[Purpose of invention]

The present invention was devised in view of the above-mentioned circumstances, and aims to provide a support mechanism that is easy to install, easy to obtain high precision, and has excellent durability.

[Summary of the idea]

In order to achieve the above object, the support mechanism of the present invention provides a spherical part at the tip of the pivot shaft that supports the main body of the lamp, a spherical seat on the main body of the lamp, and fits the spherical part into the spherical seat. In a support mechanism for an automobile lamp in which a lamp body is tiltably supported by a holder, a holder is provided with a flange on the outer periphery and a through hole with a spherical seat on the inner periphery, and a split groove is provided in the spherical seat of the holder. , insert the shaft part of the pivot into the through hole to fit the spherical part and the spherical seat, provide a through hole in the mounting piece of the lamp body, insert the spherical seat part of the holder into this through hole, and The flange of the holder is fixed to the mounting piece, and a cap is configured to fit onto the spherical seat portion of the holder, and the flange is provided on the cap, and the flange of the holder and the flange of the cap are used to secure the mounting piece. , and the pivot shaft is rotatably supported by the spherical seat of the holder.

[Example of idea]

Next, one embodiment of the present invention will be described with reference to FIGS. 6 to 13.

FIG. 6 is a sectional view of one embodiment of the support mechanism of the present invention.

Reference numeral 11 indicates a part of the lamp housing constituting the lamp body, and reference numeral 11a indicates a mounting piece formed on the lamp housing 11.

Reference numeral 12 designates a pivot shaft that supports the lamp body, and has a spherical portion 12a at its tip, and a groove 1 on its top surface for engaging the cutting edge of a cross screwdriver.
2b is provided.

A holder 13 is provided with a through hole having a spherical seat 13a that fits into the spherical portion 12a. 7th
The figure is a plan view of the holder 13, and FIG.
FIG. Spherical seat 13a of the holder 13
is a plurality of (four in this example) grooves 13b.
This makes it easy to insert and remove the spherical portion 12a. Furthermore, a flange 13c is integrally formed on this holder 13, and a rivet hole 13 is formed in the flange 13c.
Provide d.

A cap 14 is configured to fit around the outer circumference of the spherical seat 13a of the holder 13. FIG. 9 is a plan view of the cap 14, and FIG. 10 is a sectional view taken along the line XX. A flange 14a is integrally connected to the cap 14, and a rivet hole 14b is provided in the flange 14a. This rivet hole 14b is arranged to correspond to the rivet hole 13d provided in the flange 13c of the holder 13 described above. 14c is
This is an opening provided on the top surface of the cap 14 for inserting a driver into the cross-shaped driver groove 12b.

Reference numeral 15 denotes a pedestal having substantially the same shape as the flange 13c of the holder 13, FIG. 11 is a plan view thereof, and FIG. 12 is a sectional view taken along line XII-XII. 15a
are rivet holes, and the above-mentioned rivet holes 13d and 14
Arrange according to b. 15b is the pivot axis 12
This is an opening provided for the insertion of.

Mounting piece 1 of the lamp housing, which is the member to be held
A holder attachment hole 11b is provided in 1a (FIG. 6).

FIG. 13 is an exploded view of a cross section seen from a direction 90° different from the cross-sectional view shown in FIG. 6.

To assemble the mechanism of this embodiment, as shown in FIG.
and fit it into the spherical seat 13a. In this operation, the groove 13b (FIG. 7,
(Fig. 8), it can be easily carried out. The above holder 13 is attached to the mounting piece 11a of the lamp housing.
Insert it into the mounting hole 11b provided in the flange 13c.
The mounting piece 11a is brought into contact with the mounting piece 11a, and the pedestal 15 is applied from below as shown in the figure.

On the other hand, the holder 1 protruding upward from the mounting piece 11a
A cap 14 is fitted onto the outer surface of the cap 3, and its flange 14a
As a result, the mounting piece 11a and the flange 13c of the holder are sandwiched between the flange 14a of the cap 14 and the base 15, and the rivet holes 14a and 14b of the respective members are inserted into the mounting piece 11a and the base 15.
Since the holes 15b, 15a, 11c, and 13d are arranged concentrically, the holes 15b, 15a, 11c, and 13d are fastened by inserting the rivet 16. The rivet 16 may be a screw.

As described above, the support mechanism to which the present invention is applied is easy to assemble. Moreover, the holder 13 of the above embodiment does not have a structure in which it is expanded like a hinge and fitted into the mounting hole 10a like the spherical seat 8 in the known example shown in FIG. 4, so it can be easily constructed with high precision. . Further, since the cap 14 in the above embodiment does not have a structure in which a slot 7a is provided unlike the push-on fixture 7 in the known example shown in FIG. 3, it has excellent vibration resistance.
