Abstract

PURPOSE:To share a reinforce with different bumper fascia by embossing the lower end of the central portion of bumper fascia bent laterally forward to contact against the reinforce of chassis. CONSTITUTION:The bumper fascia 12 fixed to the reinforce 10 is made of synthetic resin to cover the reinforce 10. The opposite ends 12a in lateral direction of reinforce 10 are bent rearward while the central portion 12c in lateral direction of the front section 12b is bent to project forward. The lower end 12d at the central portion 13c of said front section 12b is embossed to contact with the longitudinal wall section 10a of the reinforce 10 with such size as to fix a license plate 13. The bumper fascia 12 is stopped through contact of the lower terminal 12g and the upper forked terminal 12h with the folded sections 10d, 10e formed at the upper and lower terminals of the reinforce 10.

Description

[Detailed description of the invention] Encounter Naoto Hanhadata Visit This invention is a rain force and a bread parfait.

This invention relates to an automobile bumper made of isia.

As a recent trend, a curved bumper with a central portion protruding from both ends in the vehicle width direction has been adopted in order to improve aerodynamic performance and improve design.

As shown in FIGS. 1 and 2, such a bumper includes a reinforcement 2 fixed to the vehicle body 1 via a stay (not shown) and a pan puff attached to this reinforcement 2 to form the appearance of the bumper. The bread puff Asia 3 and the reinforcement 2 are both curved with substantially the same curvature, so that the impact load from the bread puff Asia 3 is received by the reinforcement 2. In other words, if the reinforcement 2 is formed straight, the distance between the front part of the pump Asia 3 and the center part in the vehicle width direction will become wider, and if the center part of the pump Asia 3 in the vehicle width direction receives an impact. In this case, since the impact load is not effectively input to the reinforcement 2 and the impact absorption performance of the bumper is deteriorated, the reinforcement 2 is also curved (see Japanese Utility Model Application No. 57-100554).

However, since the curvature of the bumper facia 3 that forms the appearance of such a bumper differs depending on the vehicle model, etc., the reinforcement 2 must also be manufactured with a different curvature according to the curvature of the bumper facia 3. However, there was a problem in that Reinforce 2 could not be shared by different vehicle types.

B1BγW- This invention was made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a bumper for automobiles that can share reinforcement even if the curvature of the bumper facia differs depending on the type of car. It is said that

Akane1401 In order to achieve the above object, the automobile bumper of the present invention has the following features:
The lower end of the center part in the vehicle width direction of the pump asia, which is curved so that the center part in the vehicle width direction protrudes forward to cover the reinforcement fixed to the vehicle body, is embossed so as to come into contact with the reinforcement. It is characterized by

Lost” L edition Hereinafter, the present invention will be explained based on examples.

FIG. 3 and FIG. 6 are diagrams showing an embodiment of the present invention.

First, to explain the structure, reference numeral 10 in the figure is a reinforcement made of a steel plate.This reinforcement 10 has a substantially U-shaped cross section, is formed straight to the same length as the vehicle width, and has a pair of It is fixed to the vehicle body 1 by a stay 11 (one of which is omitted in FIG. 3).

On the other hand, the pump Asia 12 attached to this reinforcement 10 is made of synthetic resin and is formed in a size that covers the reinforcement IO, and both ends 12a in the vehicle width direction are bent toward the rear of the vehicle, and the front This front portion 12b is curved so that a center portion 12c in the vehicle width direction of the portion 12b protrudes forward from both end portions 12a. The lower end portion 12d of the central portion 12c of the front portion 12b is embossed to a size that allows the license plate 13 to be attached so as to come into contact with the vertical wall portion 10a of the reinforcement 10. Further, on the inside side of the pump Asia 12, there are ribs 12a that come into contact with the reinforcement vertical wall portion 10a and fitting holes 1 of the reinforcement vertical wall portion 10a at a plurality of locations.
A fitting protrusion 12f is formed to be fitted to 0b.

Furthermore, the bread puff Asia 12 has a lower terminal portion 12g.
and the upper bifurcated terminal portion 12h are the reinforcement 1.
It is designed to abut and lock onto bent portions 10d and 10e formed at the upper and lower end portions of the 0. Furthermore, insertion holes 12i and 10f for attaching the license plate 13 are formed in the lower end 12d of the pump Asia 12 and the vertical wall 10a of the reinforcement 10.

Then, the fitting protrusion 12f of the pumping Asia 12 is fitted into the fitting hole 10b of the reinforcement 10, and the terminal parts 12g and 12h of the pumping Asia are engaged with the reinforcement bending parts 10d, 10e, The pumping Asia 12 is attached to the reinforcement 10 with the lower end portion 12d and rib 12e of the pumping Asia 12 in contact with the reinforcement vertical wall portion 10a. In addition, the insertion hole 13a of the license plate 13, the reinforcement insertion hole 10f, and the bread puff Asia insertion hole 12.
The license plates 1 to 13 are fixed to the reinforcement 10 by inserting a bolt 14 through i and screwing it into a nut 15.

Next, to explain the function of the bumper constructed as described above, the vertical wall portion 1 having a reinforcement of 1°0 is formed straight.
By bringing the lower end 12d of the bread puff Asia 12 into contact with the bread puff Asia 0a, when an impact load is applied to the bread puff Asia 12, the impact is received by the lower end 12d and the rib 12g, unlike the conventional reinforcement 2. Almost the same impact absorption performance as a curved bumper can be obtained.

In this way, the lower end 12d of the bread puff Asia 12 is embossed so as to come into contact with the reinforcement 10, so that the impact is received at this lower end 12d, so that the curvature of the bread puff Asia 12 varies depending on the car model, etc. Even in the case of different curvatures, the lower end 12d can be brought into contact with the reinforcement 10 and receive the impact by simply changing the embossing depth, so the reinforcement 10 is manufactured in a way that corresponds to the pump facia 12 of different curvature. There is no need for this, and the reinforcement 10 can be shared by different vehicle types.

Furthermore, in the past, the license plate 13 was attached to the pump Asia 3, which had low rigidity, and therefore required a reinforcing member such as a nut plate.
If it is attached to the highly rigid reinforcement 10 via the embossed lower end portion 12d of the pumping Asia as in this embodiment, there is an advantage that no reinforcing member is required and it can be securely fixed.

On the other hand, as in the modification shown in FIG.
Attach the bottom of the pole 1 to the vertical wall 20a of the reinforcement 20.
It can also be attached using nuts 23 and 24.

In this way, the bread puff Asia 12 like the above embodiment
It is not the type that is attached to the reinforcement 10 with the fitting protrusion 12f, but the bolt 25, as in this modification.
In the case of the type that is attached with a nut 26, since it can be attached as described above at least at the center portion 22c of the pump Asia 22, the bolt 23 is hidden in the groove portion 22c and the appearance is improved.

By the way, when the license plate 13 is not used, a pattern can be applied to the lower end of the pumping Asia to improve its appearance.

Mizu standing shy rice As explained above, according to this invention.

Even if the curvature of the pump asia differs depending on the car model, etc., the reinforcement can be formed regardless of this, so it has the effect of being able to share the reinforcement for each car model etc. 1
