BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle bumper.

[0002]

2. Description of the Related Art As a bumper for a vehicle, there has been known a structure in which an upper bumper and a lower bumper are combined as shown in FIG. In the figure, 50 is a vehicle bumper, 5
1 is an upper bumper, 52 is a lower bumper.
This shows a state in a manufacturing process, in which the bumper 50 is supported by a jig 53 and has reached a painting process.

A hole 54 is formed in the upper bumper 51.
The lower bumper 52 is formed with a projection 55, and the upper bumper 51 and the lower bumper 52 are formed with bolt holes 56, 56, respectively. Finally, the projection 55 is engaged with the hole 54 and the bolt hole 5
The upper bumper 51 and the lower bumper 52 are integrated by tightening the bolts 6 and 56 with bolts to form a vehicle bumper.

[0004] When painting a vehicle bumper, uneven appearance between the upper bumper 51 and the lower bumper 52 causes poor appearance, so that the upper bumper 51 and the lower bumper are painted as shown in FIG. A gap S is formed between the upper bumper 51 and the lower bumper 52.
The area between the two has been devised so that it can be painted sufficiently.

Conventionally, as shown in FIG. 3, a clip 57 for temporary fixing is disposed between an upper bumper 51 and a lower bumper 52, so that the upper bumper 51 and the lower bumper 5 are provided.
The second gap S is maintained.

The clip 57 is located between left and right pieces 58, 58 forming a resilient portion, and between the pieces 58, 58.
And the spacer portion 5 integrally formed with the piece portions 58, 58
The locking portion 58a is formed on the piece portion 58 so as to curve inward. When the bumper is painted, the spacer portion 59 is inserted between the upper bumper 51 and the lower bumper 52 and the locking portion 58 is inserted.
a, 58a are locked in the bolt holes 56, 56 so that a gap S is formed between the upper bumper 51 and the lower bumper 52.

[0007]

However, according to such a conventional structure, the clip portions 57, 5
8, the engagement between the upper bumper 51 and the lower bumper 52 is held, and when the elasticity of the clip 57 decreases, the engagement between the upper bumper 51 and the lower bumper 52 can be held by vibrations during transportation of the bumper. Sometimes disappeared.

[0008]

In order to solve the above problems, the present invention comprises an upper bumper and a lower bumper, wherein one of the upper and lower bumpers is formed with a hole and the other is formed with a projection. In a vehicle bumper in which an upper bumper and a lower bumper are coupled by locking a convex portion to the hole,
On the side surface of the convex portion, an engaging groove which engages around the hole at the time of bumper coating and holds a gap between the upper and lower bumpers is formed, and an engaging groove of the convex portion opposite to the engaging groove is formed. A gap is formed between the surface and the hole, and a resilient member is inserted into the gap to maintain the engagement between the periphery of the hole and the engagement groove.

[0009]

The engagement groove formed on the side surface of the projection is engaged around the hole, and in this state, the gap formed between the surface of the projection opposite to the engagement groove and the hole is formed. A resilient member is inserted and the engagement is maintained by the resilient member. The engagement around the engagement groove and the hole is originally hard to be disengaged, and is further urged in a direction in which the engagement is held by a resilient member, so that the engagement becomes strong and may be disengaged even by vibration or the like. There is no.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view of a vehicle bumper at the time of manufacturing, and the left side of the figure is the front and the right side is the rear. In the figure, reference numeral 1 denotes a vehicle bumper. The vehicle bumper 1 is composed of an upper bumper 2 and a lower bumper 3. The vehicle bumper 1 is supported by a jig T and has reached a painting step.

The upper bumper 2 and the lower bumper 3 are formed with bolt holes 4,..., Respectively. The upper bumper 2 is formed with holes 6, and the lower bumper 3 is formed with corresponding protrusions. The parts 7 are integrally formed. Finally, the convex portion 7 is fitted into the hole portion 6 and the bolt holes 4 and 5 are tightened with bolts to complete the vehicle bumper.

An engaging groove 8 is formed on the side surface of the convex portion 7, and the engaging groove 8 is spaced from the upper surface of the lower bumper 3 by a predetermined distance. In the painting process, the engaging groove 8 is engaged around the hole 6 as shown in FIG.
Since the engaging groove 8 is separated from the upper surface of the lower damper 3, a gap S1 is formed between the upper bumper 2 and the lower bumper 3, so that the paint is also blown between the upper bumper 2 and the lower bumper 3, This part can also be coated sufficiently.

On the other hand, since the engaging groove 8 is locked around the hole 6, the side surface of the convex portion 7 opposite to the engaging groove 8 and the hole 6
A gap S2 is formed with the surroundings. In the painting step, the resilient member 10 is inserted into the gap S2. As shown in FIG. 2, the resilient member 10 includes left and right half portions 11,
12 while the one part 11 is linear, while the one part 12
Is composed of a straight base 12a, a mountain-shaped intermediate portion 12b, and a tip portion 12c that is bent inward from an end of the intermediate portion 12b. In this embodiment, the intermediate portion 12
b and the base 12a have an angle α of 10 degrees, and the mountain-shaped intermediate portion 1
The angle β formed by the vertices of 2b is set to 140 degrees, and the angle γ formed by the middle portion 12b and the tip portion 12c is set to 30 degrees. Since the resilient member 10 has the shape described above, when the resilient member 10 is inserted into the gap S2, the resilient member 10
Due to the resilience of the convex portion 7, the engaging groove 8 and the hole 6
It is urged in a direction to increase engagement with the surroundings. Then, painting is performed in this state. Thereafter, the resilient member 10 is removed from the gap S2, the engagement groove 8 is removed from the periphery of the hole 6, and the projection 7 is fitted into the hole 6 in a later step as described above. At the same time, the bolt holes 4 and 5 are fastened with bolts to complete the vehicle bumper.

According to the structure described above, during the painting process,
First, since the engaging groove 8 engages around the hole 6, the projection 7 is difficult to be removed from the hole 6 in terms of shape, and this engagement is urged and held by the elastic member 10. Therefore, the engagement is further strengthened, and the upper bumper 2
And lower bumper 3 can be prevented from coming off.

[0015]

As described above, according to the present invention, the engagement groove is engaged around the hole, and this engagement is urged and held by the resilient member. From the upper bumper and the lower bumper due to vibration or the like.
