Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bumper device for a vehicle that has bumper face sides that extend toward the sides of the vehicle body on both sides of the bumper face.

In recent years, for safety reasons, various devices have been adopted for bumpers installed on automobiles to absorb impact energy in the event of a collision, or methods of molding the surfaces and edges with resin etc. In automobiles that have bumper face sides that extend toward the vehicle body sides on both sides of the bumper face, in addition to the impact energy absorbing device provided on the bumper face, for example, the inside of the bumper face side 1 as shown in Fig. 1 is used. A rib-shaped slide member 2 having a long hole, which is fixed to the side surface, is attached to the vehicle body 3.
There was a model that engaged a slide pin 5 attached via a bracket 4 to absorb the shock applied to the side of the vehicle body, but all of these structures were complex and had a large number of parts. Moreover, since it is a rib-shaped slide mechanism, the slide member and its surroundings need to be thicker, which not only increases the weight, but also causes the edge of the bumper face side 1 to close to the vehicle body as shown in Figure 2. Since the structure is such that the vehicle rides on the fender of No. 3, there is a risk of damaging the paint film in that area or damaging the fender itself.

The present invention was developed to solve the above-mentioned conventional problems, and even if an external force is applied to the bumper and the bumper moves toward the vehicle body due to the impact, it will not damage the outer panels such as the fenders of the vehicle body. The object of the present invention is to provide a bumper device for a vehicle that is free of bumps.

The present invention will be described below with reference to illustrative embodiments.

a is a bumper attached to the front and rear ends of automobile A, which includes a bumper face 11 and a bumper face side 12;
The bumper face 11 is fixed to the front and rear ends of the vehicle body via shock absorbers (not shown) or the like, and is designed to absorb impact energy caused by a collision.

Further, the bumper face sides 12 are integrally formed continuously from both sides of the bumper face 11, and are formed so as to extend around the sides of the fender 15.

Incidentally, the bumper face side 12 may be molded separately from the bumper face 11, but in either case, its material is molded from a soft resin such as urethane.

A rib 13 is provided protruding from an inner surface 24 having a substantially U-shaped cross section at the end of the bumper face side 12, and the end portion of the bumper face side 12 is slanted outward toward the center of the vehicle body. Notched.

Reference numeral 14 denotes a side bumper provided on the vehicle body side of an extension of the bumper face side 12, which is made of the same resin material as the bumper face side 12, and is formed into a hollow shape with a substantially U-shaped cross section. Its base end is attached to the foil nose of the fender 15 with a mounting screw 16, and is attached from the fender 15 so that the side surface 18 of the side bumper 14 and the side surface 19 of the bumper face side 12 are substantially continuous and on the same surface. A prominent setting.

Further, the tip portion 20 of the side bumper 14 has a stepped portion 14a.
The stepped portion 14a is formed with a slope 23 that guides the bumper face side 12 to ride on the side surface 18 of the side bumper 14.

Furthermore, the tip 22 of the step 14a is extended between the bumper face side 12 and the fender 15 so that the tip 21 of the bumper face side 12 is covered with the step 14a of the side bumper 14, The terminal section 14
b is fitted into the end of the bumper face side 12 and attached to the fender 15 via the bracket 10.

Note that the stepped portion 14a is located on the bumper face side 12.
Like the end portion of the bumper face side 12, it is formed obliquely to eliminate gaps in the connection between the stepped portion 14a and the end portion of the bumper face side 12, thereby improving the appearance.

Bracket 1 that attaches the side bumper 14 to the vehicle body
It is even better if the bumper face side 12 is made to be made of an elastic material such as a leaf spring and attached so that it is easy to ride on the bumper face side 12, and in this case, the restorability is further improved.

Furthermore, although the side bumper 14 is hollow in the above embodiment, it may be made solid by filling the hollow part with something that is easily deformed or with a resin that is easy to deform and has good restorability. You can also use it as

As described above, according to the present invention, in an automobile having bumper face sides that extend toward the vehicle body sides on both sides of the bumper face, a side bumper made of a soft material is installed on the vehicle body side of the extended portion of the bumper face sides. At the same time, a stepped portion having a slope for guiding the bumper face side to ride on the side surface of the side bumper is formed at the tip of the side bumper, and the tip thereof is further extended between the bumper face side and the fender. Since the terminal part is fitted to the end of the bumper face side, when an external force is applied to the bumper and the bumper moves toward the vehicle body, the bumper face side slides on the side surface of the side bumper. As a result, although the bumper side may be damaged or deformed, the fender located inside the bumper side will not be damaged.

In addition, according to the present invention, the side bumper is made hollow to make it easier to deform, the stepped part of the side bumper is formed with a slope, or a rib is provided on the inner surface of the end of the bumper face side, so that the side bumper can be easily deformed. Since the bumper face side slides smoothly, there is no damage to the sliding part or to the bumper, fender, etc.

Furthermore, even if there is a slight collision, light contact, or scrape on the side of the fender, since the bumper side and bumper face side protrude from the fender, the fender will not be damaged because the bumper side and the bumper face side will be affected.

Furthermore, according to the present invention, since the bumper face side mounting part does not have a sliding mechanism like the conventional one, the number of parts is small and the assembly work is easy. Since the ribs provided on the face side make contact on three sides, assembly accuracy can be improved.

Furthermore, according to the present invention, since it is the bumper side that is easily replaced due to movement of the bumper face side, the tip of the bumper side and the tip of the bumper face side can be configured to be in close contact or with a small gap. This has the effect of making it look good without any gaps.
