Description

[Detailed Description of the Invention] The present invention relates to a vehicle lamp equipped with a front frame made of soft thermoplastic resin.

For example, a vehicle light such as a combination lamp has a front frame on its front periphery, and the part where the light is attached to the vehicle body, the joint between the front lens and the light body, etc. are exposed on the surface of the front frame. In addition, the sides of the lamp are covered, and the front frame gives the overall appearance of the lamp a beautiful appearance, increasing the commercial value of the lamp.

Therefore, the front frame used in this type of vehicle light is designed to surround the sides of the front lens, depending on the shape of the light, and has a thin wall with a generally inverted U-shape in cross section. A side edge is shaped to touch the side surface of the front lens, and the other side edge touches the outer surface of the vehicle body.

Incidentally, conventionally, in this type of vehicle lamp, the front frame is formed by bending a thin plate made of metal material such as iron, stainless steel, or aluminum, or formed from a hard resin material with a shore D hardness of 10 or more. is used.

Since these are all hard, the front frame may damage the painted surface of the vehicle body when the light fixture is attached to the vehicle body.

In addition, the side edges of the front frame that are in contact with the mounting surface of the vehicle body are thin and sharp, so vibrations and impacts during driving may cause them to intermittently hit the painted surface and cause damage to the painted surface. In particular, there were many cases where the mounting surface of the vehicle body was curved due to manufacturing problems and only partially touched the side edge of the front frame.

Rust occurs from the parts where the paint film has been peeled off, and this rust sometimes stains the surface of the car body and shortens the life of the car body.

Therefore, it has been considered to attach an elastic member to the side edges of the front frame, or to form a recess on the mounting surface of the vehicle body to prevent the side edges from colliding with each other, but both methods are expensive. , it was also unsightly and impractical.

In addition, as mentioned above, if the front frame is hard and has sharp corners on the outside due to its shape, it will be dangerous if it comes into contact with it, so it is necessary to make those parts rounded. .

Therefore, the degree of freedom in the design of the front frame is extremely reduced, and as a result, there is a drawback that the appearance of the lamp becomes uniform to some extent.

In view of these points, this invention has a front frame with Shore A hardness of 5.
It is made of soft thermoplastic resin material with a Shore D hardness of 0 to 70, which does not damage the painted surface of the car body, and is safe even when formed into a sharp shape. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a vehicular lamp which can be formed into a shape.The present invention will be explained in detail below using an embodiment shown in the drawings.

1 and 2 show an embodiment in which the vehicular lamp according to the present invention is applied to a combination lamp, and in these figures, the vehicular lamp includes a lamp body 1,
The lamp body 1 includes a front lens 2 that covers the front surface of the lamp body 1 and a front frame 3 that surrounds the front lens 2, and a socket 5 fitted with a pulp 4 is fitted into the front lamp body 1.

The entire lamp body 1 is integrally formed of a synthetic resin material or the like, and has a flange 6 at its opening.

The top surface of this flange 6 has a front lens 20 peripheral edge tip 7.
A lens joint part 9 is formed in which the lamp body 1 is joined to the vehicle body 11 through a seat backing 10.
A plurality of mounting holes 14 are bored at predetermined intervals.

The tip of the flange 6 extends outward beyond the lens joint 9, and the extension 15 includes a screw mounting portion 11 in which a screw 16 for fixing the front frame 3 is embedded, and a screw mounting portion 11 for positioning and holding the front frame 3. A plurality of upwardly protruding projecting parts 18 are formed on the extension part 15 of the flange 6 so as to correspond to the mounting cylinder parts 19 and positioning ribs 20 of the front frame 3, which will be described later.

Now, according to the present invention, the front frame 3 is
As shown in the figure, it is integrally formed of a soft thermoplastic resin material with a Shore A hardness of 50 to Shore D hardness of 70 so as to surround the front side of the lamp.

This front frame 3 is a part that characterizes the present invention, and has an approximately inverted U-shaped cross section, and its inner edge 3a faces closely to the side outer surface of the front lens 2, and extends around the peripheral edge of the front lens 2. At the same time, the outer edge 3b is extended obliquely toward the lower I/C #A so that the outer edge 3b is in contact with the surface of the vehicle body 110.

The front frame 3 is formed to have a thin wall thickness 5.

Further, on the inner surface of the top portion 3c of the front frame 3, as shown in FIG.
and positioning ribs 20 are provided protrudingly at predetermined locations.

(See Figure 1) These correspond to the screw attachment part 17 and the protruding part 18 of the lamp body 1, and they fix the front frame 3 to the lamp body 1 and prevent the soft front frame 3 from being deformed by external force. This is to prevent the lamp from being damaged and to hold it in the lamp.

Therefore, the tip of the cylindrical portion 19 comes into contact with the screw attachment portion 17 of the lamp body 1, and the screw 16 inserted from the back side is screwed into the columnar portion 19.

Further, the outer surface of the rib 20 is locked to the inner surface of the protrusion 18 of the lamp body 1, so that the front frame 3 can be attached to the front frame 3 when attaching the front frame 3 to the lamp body 1, or when washing a car. Place the front frame 3 on top of the lamp body 1 to prevent the front frame 3 from being deformed due to excessive force being applied to the front lens 2, causing the inner edge 3a to become too far away from the front lens 2, and to prevent the gap between the inner edges 3a from becoming uneven. It is held in

In this case, the cylindrical part 19 may be provided protrudingly at a predetermined location on the inner surface of the front frame 3, and the rib 20 may be formed below the cylindrical part 19 over the entire circumference, or may be formed partially.

Note that by applying surface treatments such as vacuum deposition, sputtering, and painting to the surface of the front frame 3, it is possible to give the front frame a metallic feel without losing the elasticity and flexibility of the front frame 3. can.

A vehicle lamp having such a structure is assembled as follows.

That is, the pulp 4 and the socket 5 are attached to the lamp body 1, and the front lens 2 is joined above it via the gasket 8.

Then, the screw attachment part 17 and the protruding part 18 on the extension part 15 of the flange 6 protruding outward from this joint part are aligned so that they correspond to the columnar part 19 and the rib 20 of the front frame 3, respectively, Further, the front frame 3 is placed over the lamp body 1 from above, and the front frame 3 is fixed to the lamp body 1 with screws 16 so that the inner side edge 3a is in uniform contact with the side outer surface of the front lens 2.

At this time, the outer side edge 3b of the front frame 3 is projected in a downwardly inclined state than the seven flange 6 of the lamp body 1.

Further, a bolt 12 is fitted into the mounting hole 14 of the seven flange 6 from inside the lamp body 1.

In order to attach the vehicle lamp assembled in step 5 to the car body 11, align it so that the pulp attachment part of the light body 1 centerpiece is fitted into the inside of the car body 11 through the opening formed in the car body 11, Furthermore, the tip of the bolt 12 protruding downward from the lamp body 1 is aligned with a hole previously drilled in the peripheral edge of the opening of the vehicle body 11.

Then, with the seat backing 10 interposed below the flange 6 of the lamp body 1, bolts 12 and nuts 13 protruding from the back side of the vehicle body 11 are used to tighten and fix the lamp body.

At this time, the outer edge 3b of the front frame is pressed against the surface of the vehicle body 11 due to its elasticity, and is in uniform contact with the surface of the vehicle body 11.

In the above-mentioned vehicular lamp mounted on the vehicle body 11 as shown in FIG. As shown in FIG. 2, the side edge 3b does not damage the painted surface even if it comes into close contact with the surface of the vehicle body 11, and the surface is formed in a shape with corners. It is also less dangerous and has excellent safety aspects.

Therefore, the shape of the front frame 3 can be changed in various ways, which has the advantage of increasing the degree of freedom in design.

Furthermore, according to the present invention, even if the inner side edge 3a of the front frame 3 is brought into contact with the side of the front lens 2, the impact force due to vibrations, impacts, etc. is not applied to (absorbed by) the front lens. This allows the front lens to be safely protected without the risk of destroying the front lens due to the hard front frame as in the conventional case.

The reason why the front frame 3 is made of materials with a Shore A hardness of 1i50 to a Shore D hardness of 70 is because if the Shore D hardness is 70 or more, it will cause damage to the painted surface of the car body as in the past, and if the Shore A hardness is 501J. This is because in the case below, the moldability is poor and molding is difficult.

In the above embodiment, the positioning rib 20 formed on the inside of the front frame 3 was engaged with the protruding portion 18 that protruded from the 7 flange 6 of the lamp body 1, but the present invention is different from this. Without limitation, as shown in FIG. 3, it may be locked to an L-shaped locking part 21 protruding from the side of the front lens 2.

Further, although the inner side edge 3a of the front frame 3 is made into contact with the side outer surface of the front lens 2, the present invention is not limited to this, and as shown in FIG. It may also be configured to lock onto the peripheral edge portion of the front lens 2.

Furthermore, in the embodiment described above, the front frame 3 is fixed to the lamp body 1 using the screws 16, and the lamp body 1 is further fixed to the upper side of the vehicle body 11 with the bolts 12 and nuts 13. The assembly structure of the light body 1, front lens 2, and front frame 3, and the vehicle body 11 of these are not limited to this.
Various structures can be considered for installation.

For example, as shown in FIGS. 5 and 6, the front frame 3
A bolt 23 is embedded in the cylindrical portion 19 of the bolt 23.
It may also be used for fixing to the lamp body 1 and the vehicle body 11.

FIG. 5 shows that the front frame 3 is placed above the vehicle body 11, and
A case is shown in which the flange 24 on which the front lens 2'VC is formed and the flange 6 of the lamp body 1 are fixed via the backing 25, and FIG. A case is shown in which the flange 6 and front frame 3 are fixed.

In short, any structure is sufficient as long as the front frame is formed to surround the front side of the lamp, the inner edge faces the outer surface of the front lens, and the outer edge extends so as to touch the surface of the vehicle body.

As explained above, in the vehicle lamp according to the present invention, the front frame provided on the front side of the lamp is integrally formed of a soft thermoplastic resin material with a Shore A hardness of 50 to a Shore D hardness of 70. Even if the side edges of the thin front frame come into close contact with the surface of the vehicle, it will not damage the painted surface, and regardless of the shape of the front frame, it is excellent in terms of safety, and its design The degree of freedom can be increased.

Furthermore, according to the present invention, the front frame can be easily molded, and even if there is a slight difference in the dimensions of the front frame or the mounting part of the vehicle body, it can be absorbed by elasticity, so strict dimensional accuracy is not required as in the past. It is not necessary, and manufacturing costs can be reduced.
