Description

[Detailed Description of the Invention] This invention relates to a support device for the corners of a bumper attached to the front and rear of an automobile body.

As the above-mentioned support device, for example,
As shown in FIG. 7 of Publication No. 25538, an engaging portion is integrally formed on the periphery of a corner portion of the bumper main body which has a substantially U-shaped cross section, and on the other hand, the engaging portion is formed on a side surface of the vehicle body opposite to the corner portion. A locking receiving part is protrudingly provided to allow the bumper body to slide back and forth in the longitudinal direction of the vehicle body, so that the bumper body can easily move back and forth when receiving an external force, and the corner part can be assembled. Conventionally, there has been known a device designed to improve the performance of the bumper, in which a first engaging portion is provided at the lower end of the periphery of the corner portion in order to restrict upward blind movement of the bumper corner portion with respect to the side surface of the vehicle body. On the other hand, the first
A first locking receiving part that engages with the engaging part of the corner part is provided, and a second locking part is provided at the upper end of the periphery of the corner part in order to restrict downward blind movement of the corner part with respect to the side surface of the vehicle body. While the engaging portion is provided, the locking member is configured to include a second locking receiving portion that engages with the second engaging portion on the upper edge of the locking member, so that the upper and lower edges of the corner portion In order to restrict the blind movement of the corner part, it is necessary to provide two engaging parts and two locking receivers at the upper and lower ends of the corner part and the locking member, respectively. Therefore, the supporting structure of the corner part is It has drawbacks such as being complicated and large, increasing cost, and being troublesome to assemble.

The present invention has been proposed in view of the above, and an object of the present invention is to provide a bumper support device for an automobile that is simple in structure and easy to process, without the drawbacks of the conventional devices, although the engaging portion is formed on the periphery of the bumper corner portion. purpose.

In order to achieve such an object, the present invention has a bumper main body that is attached to the front and rear surfaces of an automobile body and has corner portions having a substantially U-shaped cross section at both ends, and a bumper main body that is attached to the front and rear surfaces of an automobile body, and has corner portions having a substantially U-shaped cross section at both ends; An engaging portion extending inward from the periphery of the vehicle body is integrally molded from a synthetic resin material, while a side surface of the vehicle body facing each of the corner portions is provided with a portion such that the engaging portion can slide in the longitudinal direction of the vehicle body. A locking receiving portion that can be locked is provided in a protruding manner, and the engaging portion is formed in a U-shape in which a cross section perpendicular to the longitudinal direction of the vehicle body opens outward from the vehicle body;
Further, the locking receiving portion has a cross section perpendicular to the longitudinal direction of the vehicle body that opens toward the vehicle body in order to lock the engaging portion so as to restrict movement thereof in the vertical direction and toward the outside of the vehicle body. It is characterized by being formed in a U-shape.

An embodiment of the present invention will be described below with reference to the drawings. A bumper body 1 to be attached to the front and rear sides of an automobile V is made of synthetic resin and has a generally U-shaped cross section, with both ends curved into an L-shape to form corner portions 1a.
A synthetic resin engaging portion 2 is provided on the upper peripheral edge along the longitudinal direction of the vehicle body, and extends toward the inside of the vehicle body, and the cross section of this engaging portion 2, i.e., the cross section perpendicular to the longitudinal direction of the vehicle V, is U-shaped and opens outward toward the outside of the vehicle body. The engaging portion 2 is injection molded integrally with the bumper main body 1 when it is molded.

On the vehicle body side surface 3 facing each corner portion 1a of the bumper main body 1, a locking receiving portion 4 capable of removably locking the engaging portion 2 is provided in a protruding manner. This locking receiving part 4 has a U-shape in which its cross section, that is, the cross section perpendicular to the longitudinal direction of the vehicle body, opens toward the vehicle interior, and a bifurcated clip 5 is integrally formed at its base.
A mounting hole 6 for this clip 5 is drilled in the side surface 3 of the vehicle body.
to fix the locking receiving part 4 to the side surface 3 of the vehicle body.
The mounting hole 6 is covered by a cover body 7 which is inserted into the clip 5.

When the bumper main body 1 is mounted on a vehicle body, as shown in FIG. They are mutually slidable in the longitudinal direction of the vehicle body, and when an external force in the longitudinal direction is applied to the bumper main body 1, the engaging portions 2 and The locking receiving part 4
slide relative to each other to allow movement of the bumper main body 1.

As described above, according to the present invention, each corner portion 1a of the bumper main body 1, which is attached to the front and rear surfaces of the vehicle body, has a substantially U-shaped cross section, and the periphery along the front and back direction of the vehicle body is provided with a radial groove extending toward the inside of the vehicle body. An extending engaging portion 2 is integrally formed, and a locking receiving portion is provided on the side surface 3 of the vehicle body facing each corner portion 1a, and is capable of locking the engaging portion 2 so as to be slidable in the longitudinal direction of the vehicle body. 4 is provided protrudingly, and the engaging portion 2 is formed in a U-shape in which a cross section perpendicular to the longitudinal direction of the vehicle body opens outward from the vehicle body,
Further, the locking receiving part 4 is configured such that a cross section perpendicular to the longitudinal direction of the vehicle body is oriented toward the interior of the vehicle body in order to lock the engaging part 2 so as to restrict its movement in the vertical direction and toward the outside of the vehicle body. Since the bumper corner portion 1a is formed in an open U-shape, by providing only one set of the engaging portion 2 and the locking receiving portion 4, which have a simple U-shaped cross section, the bumper corner portion 1a can be attached to the side surface of the vehicle body. 3 can be reliably connected and supported in both the upper and lower and left and right directions, and therefore the support structure of the corner portion 1a is extremely simple, contributing to cost reduction and improved assemblability. Moreover, at the peripheral edge portion of the bumper corner portion 1a that is closest to the vehicle body side surface 3,
Since the engaging portion 2 is formed extending toward the side surface 3 of the vehicle body, not only the length of the engaging portion 2 itself but also the length of the lock receiving portion 4 protruding from the side surface 3 of the vehicle body can be shortened. This contributes to increasing the rigidity of the engaging portion 2 and the locking receiving portion 4, and in addition, the engaging portion 2 and the locking receiving portion 4 have a simple U-shaped cross section and are relatively lightweight. Coupled with the fact that it can be formed thin, it can also contribute to reducing the weight of the vehicle.

Furthermore, since the bumper main body 1 and the engaging part 2 are integrally molded from a synthetic resin material, when molding them, the direction in which the bumper main body 1 is molded out and the direction in which the engaging part 2 is molded out are made to coincide with each other in the front-rear direction. It is possible to use the same mold for both, which simplifies the molding process, and it is also possible to perform special processing such as drilling holes on the engaging portion 2, or to replace the engaging portion 2 with the bumper main body 1.
There is no need to fix the structure with bolts or the like, which can contribute to cost reduction.
