Abstract

PROBLEM TO BE SOLVED: To allow to displace a lighting body in a good condition even to an external force from the oblique direction. SOLUTION: A tilting stay 7 is provided to a body fixing member 6, and while the diameter expanding part of a bolt with step 9 screwed up to a bracket 2 which is formed integral to a headlamp 1, and the slit 7a in the radius direction of the tilting stay 7, are engaged, an engaging projection 2b provided to the bracket is engaged to the slit 7a in the radius direction. A claw 7b provided to the tilting stay 7 is abutted to the body fixing member 6. When the headlamp 1 is displaced to the rear side by an external force in a collision, the engagement of an engaging projection 2b and the slit 7a in the radius direction is released by an input more than a specific load, the claw 7b is bent, and the tilting stay 7 is tilted, so as to absorb the impact force operating to the headlamp 1. Furthermore, the bolt with step 9 can be removed from the slit 7a in the radius direction. Since the headlamp 1 can be displaced by the tilting operation of the tilting stay 7, the headlamp 1 can be displaced even to an external force from the oblique direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lighting structure for mounting a vehicle lighting body on a vehicle body.

[0002]

2. Description of the Related Art There are vehicles equipped with, for example, a headlamp as a vehicle lighting body so as to be substantially flush with a surface of a bumper. For example, when the bumper and the headlamp collide with an obstacle, the bumper is deformed. There is one that absorbs the impact force, but also the headlamp is displaced rearward so that the impact force in the headlamp is also absorbed.

As such a conventional headlamp mounting structure, there is one shown in FIG. 8, for example. In FIG.
A bracket 22 is integrally attached to a side wall of the headlamp 21, a slide groove 23 extending in the vehicle front-rear direction is formed in the bracket 22, and a guide fixed to a stay 24 fixed to the vehicle body by, for example, screwing. Member 2
5 is engaged with the slide groove 23 to position and fix the headlamp 21.

In the headlamp mounting structure having the above structure, when the headlamp 21 is displaced rearward during a frontal collision, the bracket 22 slides together with the headlamp 21 while the guide member 25 is fixed to the stay 24. As shown in the phantom line in the figure. Since this sliding direction is the extending direction of the slide groove 23, that is, the front-back direction of the vehicle body, it may be considered that the sliding direction cannot be suitably performed with respect to an oblique input, for example.

[0005]

In view of the problems of the prior art, the main object of the present invention is to suitably displace the lamp body even when an external force in an oblique direction acts on the lamp body. It is to provide a vehicular lamp structure that can be used.

[0006]

According to the present invention, a bracket integrally formed with a vehicle lamp body attached to a vehicle body and a lever-shaped one end portion of which is tiltable with respect to the vehicle body. A stay having a slit that is supported on the other end and that is open outward in the radial direction at the other end, an engaging member that is integrally provided on the bracket so as to engage with the slit, and acts on the lamp body. The external force acts on the lamp body by having the positioning means for positioning the stay obliquely with respect to the displacement direction of the lamp body by the external force and holding the positioning state until the external force exceeds a predetermined value. In this case, since the stay can rotate about the rotation axis, it is possible to allow a wide range of directions in which the lamp body is displaced due to the difference in the direction of the external force. In particular, the positioning means is provided with a locking claw which is formed on either one of the stay and the vehicle body and abuts against the other and is deformed by an external force of a predetermined value or more, or the positioning means Is provided with a shaft member that is cut by a shearing force equal to or more than a predetermined value in the rotation direction of the stay at the overlapping portion between the stay and the vehicle body, or the positioning means is provided between the stay and the vehicle body. A convex portion formed on either one of the above and a concave portion formed on the other of the stay and the vehicle body so as to engage with the convex portion, and the convex portion and the concave portion The engagement state may be maintained until the turning force of the stay exceeds a predetermined value. Alternatively, a bracket integrally formed at a position separated from the fixed portion of a vehicle lighting body having a fixed portion fixed to the vehicle body and a lever-shaped one end portion of which is tiltable with respect to the vehicle body A stay having a slit open to the outside in the radial direction at the other end, and the lamp body is held in a state of being attached to the vehicle body in cooperation with the fixing portion, and an external force is applied to the lamp body. The same operation can be achieved by having an engaging member integrally provided on the bracket so as to engage with the slit in order to rotate the lamp body about the fixed portion as a fulcrum when actuated.

[0007]

1 is an exploded perspective view of an essential part showing a vehicle headlamp 1 as a lamp body to which the present invention is applied. The headlamp 1 is attached to a vehicle body (not shown) via mounting brackets 2, 3, 4, 5 protruding from four positions of the main body.

A pair of upper and lower mounting brackets 2 and 3 located on the side surface of the vehicle body in the mounted state of the headlamp 1 are integrally formed, for example, so as to extend vertically on the upper surface and the lower surface of the main body of the headlamp 1. Is formed. In addition, another pair of mounting brackets 4 and 5 located inside the vehicle body
Is similarly integrally formed so as to project inward at each of the upper and lower positions of the side surface corresponding to the inside of the vehicle body.

The attachment brackets 2 to 5 and the vehicle body are coupled to each other through the long plate lever-like tilt stays 7 pivotally attached to the vehicle body fixing members 6 bolted to the vehicle body side. It has become. The tilt stay 7 is attached to the vehicle body fixing member 6 so as to be tiltable via a pin 8 that penetrates one end in the longitudinal direction of the tilt stay 7 in the plate thickness direction. Further, the tilt stay 7 is formed with a radial slit 7a extending from the central portion in the longitudinal direction to the other end. The radial slit 7a is opened at the free end of the tilt stay 7 on the side opposite to the pivotal support side of the pin 8. Claws 7b are formed at appropriate positions on both side edges along the longitudinal direction of the tilt stay 7, and the claw 7b is brought into contact with the edge of the vehicle body fixing member 6 to determine the position of the tilt stay 7 at the time of mounting. Positioning means is configured.

The mounting brackets 2 to 5 have different structures but have the same structure. Therefore, one of the mounting brackets 2 will be described below. Tilt stay 7 of mounting bracket 2
A pin hole 2a as a positioning means is provided in a portion facing
And an engaging protrusion 2b. These pin holes 2a
The engaging projections 2b are arranged so as to be aligned with the radial slits 7a of the tilt stay 7 in the above-described mounted state.

To install the headlamp 1, the nut 1
0a is attached to the U-shaped metal fitting 10 and the nut 10
mounting bracket 2 so that a and pin hole 2a are aligned
Attach it between the two. Next, each claw 7b is brought into contact with the edge of the vehicle body fixing member 6 to position the tilt stay 7,
The stepped bolt 9 is screwed into the nut 10a while the radially enlarged portion 9a of the stepped bolt 9 serving as an engaging member is engaged with the radial slit 7a, and the engagement protrusion 2b is engaged with the radial slit 7a. The tilting stay 7 and the mounting bracket 2 are joined together. In addition, other mounting brackets 3 ~
The connection of each tilting stay 7 to 5 is similarly performed.

In the headlamp 1 thus mounted on the vehicle body, when some obstacle 15 collides with the headlamp 1 from, for example, an obliquely upper position as shown in FIG. 2, it is indicated by an arrow A in the figure. Thus, the headlamp 1 tries to displace to the rear side of the vehicle body. At this time, the tilt stay 7
When an external force is applied to the headlamp 1 such that the radial slit forming portion of the above goes over the engaging protrusion 2b and breaks the pawl 7b of the tilt stay 7 on the side to be tilted, as shown by an arrow B in FIG. The tilting stay 7 tilts, and the headlamp 1 is displaced slightly downward as indicated by an arrow C according to the movement of the tilting stay 7.

Then, as shown by the arrow D in FIG.
Since the stepped bolt 9 integrated with the headlamp 1 can be detached from the opening of the radial slit 7a, when a strong impact force is applied, the headlamp 1 and the vehicle body are separated from each other as shown in FIG. Is released, the stepped bolt 9 is disengaged from the radial slit 7a, and the headlamp 1 falls off from the vehicle body. This causes interference between the obstacle and the headlamp 1 at the time of collision. The influence on the body can be suppressed as much as possible. Further, the headlamp 1 itself also escapes from the impact, and the damage can be prevented.

In the above-described embodiment, the headlamp 1 is connected to the vehicle body at the four positions with the same structure. However, as shown in FIG. 5, one side portion (side of the vehicle body) of the headlamp 1 is a tilt stay. Instead of this, for example, it may be fixed by a bolt 11 to form a fixed portion, and the other side portion (inside the vehicle body) may be joined with the same structure as the above-described embodiment. In FIG. 5, the same parts as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

When an external impact force is applied to the headlamp 1 as shown by an arrow E in FIG. 5, the headlamp 1 tries to rotate about the fixed end as a fulcrum as shown by an arrow F in the figure. Then, since the tilt stay 7 can tilt as shown by the arrow G, the headlamp 1 can rotate about the fixed end as a fulcrum and be displaced rearward of the vehicle body to achieve the same effect as that of the above embodiment.

In the above embodiment, the bending force of the pawl 7b for positioning the tilting stay 7 and the engaging force between the engaging projection 2b and the radial slit 7a cause the tilting stay 7 to be moved by an external force larger than a predetermined value. Although the tilting start load is determined, either one may be used.

Further, as shown in FIG. 6, the shear pin 1 is provided between the tilt stay 7 and the mounting bracket 2 (3-5).
2 may be provided, and the shear pin 12 may be sheared when the load for tilting the tilting stay 7 exceeds a predetermined value.

Further, as shown in FIG. 7, a convex portion 13 is provided on one of the tilt stay 7 and the mounting bracket 2 (3 to 5) and a concave portion 14 having a complementary shape is provided on the other. Alternatively, when the headlamp is mounted, the tilt stay 7 may be tilted by engaging them as shown in the figure and relatively separating them by an external force of a predetermined value or more.

[0019]

As described above, according to the present invention, the lamp body is attached to the bracket on the vehicle body side through the stay that can be tilted by an external force of a predetermined amount or more, and a load of a predetermined amount or more is applied to the lamp body by a collision. In this case, since the positioning means is released and the stay tilts, the lamp body can be easily displaced toward the vehicle body side, so that the impact force of the lamp body can be appropriately absorbed. At this time, since the stay tilts, the lamp body can be effectively displaced against a collision force from a wider direction with respect to the structure in which the stay is simply slid.
