[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a license plate bracket for attaching a license plate (so-called license plate) of a vehicle to a body.

[0002]

2. Description of the Related Art Conventionally, a license plate of a vehicle is attached to a body via a license plate bracket having relatively long legs. Such a bracket includes a plate fixing portion to which a license plate is fixed, and a bracket leg connecting the plate fixing portion to the body side, and is used, for example, for mounting a rear license plate of a passenger car. . This is because when a large rear bumper having a large amount of protrusion from the rear end of the body is employed, the rear license plate is also fixed at a position protruding from the rear end of the body. In general, the bracket leg fixed to the body protrudes toward the notch formed in the rear bumper, and the license plate is fixed to the plate fixing part formed at the protruding end so that the license plate fits in the rear bumper notch It is usually done.

[0003]

Conventionally, a license plate bracket of this type has a high rigidity against a compressive load applied to its bracket legs, and therefore, for example, in a low-speed collision while the vehicle is moving backward, the license plate bracket exceeds the shock absorbing capacity of the bumper. If an impact is applied and the license plate is reached,
The impact is transmitted directly to the body, which may cause deformation of the body.

In order to prevent the deformation of the body, it is conceivable to increase the rigidity of the body structure. However, it is necessary to increase the thickness of the body or to add reinforcement (reinforcing material). In this case, weight increase and cost increase are inevitable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a license plate bracket having a high shock absorbing effect that can prevent or reduce the deformation of a body due to an impact by using a license plate bracket, not by increasing the rigidity of the body. is there.

[0006]

A license plate bracket according to the present invention is premised on a structure having a plate fixing portion and a bracket leg integral with the plate fixing portion, and the buckling load of the bracket leg is applied to the bracket leg. At least one of a crush bead and a crush hole for reducing the size In some cases, only a crash bead, only a crash hole, or both may be provided, and in any case, the buckling of the leg against the compressive load acting on the bracket leg is performed. It serves the function of making it easier to occur.

[0007]

Therefore, if the present invention is applied to, for example, a rear license plate bracket, the impact due to the collision at the time of retreat causes buckling of the bracket leg from a crash bead or a crash hole formed in the bracket leg, which causes As a result, the shock is absorbed and the body damage is reduced.

1 shows a rear license plate bracket 1 according to one embodiment of the present invention. This is, as shown in FIG. 4, the notch 4 of the rear bumper 3 of the passenger car 2.
And the rear license plate 6 is attached to the body 5.

As shown in FIG. 1, this bracket 1
It is made of sheet metal by metal press molding, and has a plate attaching portion 7 to which a rear license plate 6 is attached.
A pair of bracket legs 8 extend integrally from both ends. As a whole, as shown in FIG. 3 in a plan view, the bracket has a substantially equilateral trapezoidal bracket shape, and a portion corresponding to the upper side of the trapezoidal shape is the plate fixing portion 7.

Returning to FIG. 1, two nut members 9 are fixed inside both ends of the plate fixing portion 7, and screw members for fixing the rear license plate 6 are screwed into these nut members 9. Has become.

The bracket legs 8 on both sides are attached to the body 5.
The end on the side is bent outward to form fixing portions 10 to the body 5, and the fixing portions 10 are fixed to the body 5 by, for example, spot welding.

The bracket leg portion 8 is in the form of a laterally equilateral trapezoidal shape whose width becomes smaller toward the plate mounting portion 7 when viewed from the side, and its upper and lower oblique sides (upper side and lower side).
, A crush bead 12 is similarly formed. As is clear from FIG. 3, the crush bead 12 is one in which each of the upper side and the lower side of the bracket leg 8 is locally bulged outward by press working. The thickness is almost the same as the other parts,
The swelling form is, for example, trapezoidal, U-shaped, or arc-shaped. The direction of each bead 12 is formed to be short in a direction substantially perpendicular to the length direction of the bracket leg portion 8 (vertical direction when mounted on the body 5). Some of the crush beads 12 are located.

A substantially long hole in the length direction is formed as a crash hole 13 at a substantially central portion in the length direction of each bracket leg 8. This crash hole 13
Are formed so as to penetrate the bracket legs 8, and the positions thereof correspond to the upper and lower crash beads 12, and the respective crash beads 12 are positioned above and below the crash hole 13.

Since the bracket legs 8 on both sides have the same structure, the crash beads 12 are formed on each side in a total of four.
The crush bead 12 and the crush hole 13 are formed in the length direction of the leg 8 in the bracket leg 8. Is the weakest part with respect to the compressive load acting on

In the rear license plate bracket 1 as described above, the rear bumper 3 shown in FIG.
When the impact force F acts on the rear license plate bracket 1 as shown in FIG. 2A, the bracket leg 8 receives the impact force F (compression load), and is crushed from the crush bead 12 and the crash hole 13 and buckled ( FIG. (B). This absorbs the impact and reduces the damage on the body 5 side.

In the above embodiment, the crush beads 12
And the crush hole 13 are provided, but only one of them may be provided. Further, the number of formed parts and the parts to be formed can be appropriately changed.

Further, the present invention is not limited to the bracket for the rear license plate, but is similarly applicable to that for the front.

[0018]

According to the license plate bracket of the present invention, the crush bead and / or the crush hole formed on the bracket leg thereof have a rigidity against a compressive load in the leg length direction of the bracket leg. It becomes a weak part and buckles due to the impact force acting in that direction and absorbs the impact energy. Therefore, damage on the body side is reduced, and deformation of the body is avoided or reduced. This is particularly effective for a collision occurring at a low speed (for example, a collision when the vehicle is moving backward).

This technique does not increase the rigidity of the body by increasing the thickness of the body or adding a reinforcing material, but uses a license plate bracket, which is an essential component, to increase the rigidity of the body. By providing the shock absorbing function, the body is prevented from being damaged or deformed, so that the weight is not increased and the cost is hardly increased. Further, when a crash hole is formed, it contributes to a reduction in vehicle weight.
