Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention attaches to a frame in which a side member and a first cross member are riveted together and a riveting operation hole is formed in the first cross member. The present invention relates to a front bumper mounting structure for mounting a front bumper via a member.

[Prior Art] Conventionally, a front bumper has been mounted on a side member of a frame together with a tilt hinge bracket by a bracket.

Therefore, the bracket becomes rigid and large, and the front end portion of the side member is provided with the tilt hinge bracket, the towing hook, the steering gear box, and the like, and the first cross member is riveted. Mounting the front bumper on the bracket was troublesome.

[Problems to be Solved by the Invention] On the other hand, in the Japanese Utility Model Laid-Open No. 59-11944, the present applicant provides a shock absorbing member between the first cross member and the bumper body, and the member and the first cross member. A technique has been proposed in which a space is formed between the member and the bumper body, and the first cross member receives an impact force and backs up the impact protection action of the bumper.

Although the technique itself is effective, the shock absorbing member is large and the structure is complicated.

Further, the applicant of the present invention discloses in Japanese Utility Model Application Laid-Open No. 62-153161 that both ends of the first cross member are extended from the side to the rear and are connected to the end portions of the second cross member which is extended to the side to form the first cross. A technology is proposed in which the front bumper is attached to the member and the impact force is received by the second cross member.

The technique itself is effective, but its structure is complex.

On the other hand, the applicant of the present application has proposed a step device for cleaning a front window of a front bumper in Japanese Utility Model Laid-Open No. 60-106858, but it requires a support rigidity when a person gets on the step.

An object of the present invention is to provide a front bumper mounting structure having a simple structure, a compact structure, and an impact force which is easily mounted on the front surface of the frame.

[Means for Solving the Problems] According to the present invention, a bracket is provided, one surface of which abuts the front surface of the first cross member and the other surface of which abuts the rear surface of the mounting member, and the bracket has the first cross member. A through hole for fastening the member and the mounting member is bored, and a through hole for fastening the mounting member is bored in the portion of the rivet fastening hole of the bracket, and the bracket is provided around the first cross member. Stop means is provided, and the bracket is sandwiched between the first cross member and the mounting member by a fastening member.

Further, according to the present invention, the detent means is composed of a bent portion that bends the upper or lower portion of the bracket and contacts the upper surface or the lower surface of the first cross member.

Further, according to the present invention, the detent means is composed of a detent member mounting hole formed in the first cross member.

It is preferable that a weld nut facing the through hole of the bracket is provided inside the first cross member, and a weld nut facing the through hole is provided on the rear surface of the bracket.

[Operation] In the front bumper mounting structure configured as described above, the bracket is mounted to the first cross member by the rotation stopping means. Next, the bolt is inserted into the through hole of the mounting member and the bracket and screwed into the weld nut of the first cross member, the front bumper is mounted to the first cross member via the bracket, and then the bolt is attached to the mounting member and the bracket. Insert it through the through hole and screw it into the weld nut of the bracket to attach the front bumper to the bracket.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 3, a first cross member 2 is rivet-fastened via a spacer 3 to a front end portion of a side member 1 of a frame, and a tilt hinge bracket 4 is bolt-fastened.

A hook 5 is attached to the first cross member 2 via a spacer 3, and rivet fastening work holes 2a are formed at both ends.

On the other hand, mounting work holes 6a are formed on both sides of the license plate 7 of the front bumper 6, and a bumper member 8 which is a mounting member extending laterally from the rear of the hole 6a has a bumper member 8a.
Have been riveted to. And bumper member 8
Are attached to the first cross member 2 via the bracket 10. The bracket 10 is the first cross member 2
And the front portion 11 that is sandwiched between the opposing surfaces of the bumper member 8 and
And a bent portion 12 that is a rotation preventing means that comes into contact with the lower surface of the first cross member 2. Its front
Reference numeral 11 covers a large part of the rivet fastening work hole 2a of the first cross member 2, and a bumper mounting hole 13 is bored substantially in the center of the covered portion, and a weld nut is provided at the rear of the hole 13. 14 are provided.

On the other hand, on the inner vertical surface and the lower surface of the first cross member 2,
Weld nuts 9a and 9b for mounting the bracket 10 are attached, and the bracket 10 has through holes 15 and 16 facing the weld nuts 9a and 9b. Symbols in the figure
8a and 8b are mounting holes formed in the bumper member 8;
Is a bolt for mounting the bumper.

With this configuration, when mounting the front bumper 6, a bolt (not shown) is inserted into the through hole 16 of the bracket 10 and screwed into the weld nut 9b to mount the bracket 10 to the first cross member 2.

Next, use the mounting work hole 6a to attach the bolt 17 to the mounting hole.
8a, through the through hole 15, screwed and welded to the weld nut 9a, and the front bumper 6 is attached to the first cross member 2 via the bracket 10. Next, attach the bolt 18 to the mounting hole.
8b, through the through hole 13, and screwed and welded to the weld nut 14 to attach the front bumper 6 to the bracket 10.

FIG. 4 shows another embodiment of the present invention, in which the detent means of the bracket 10A is composed of a bent portion 12A that abuts on the upper surface of the first cross member 2.

FIG. 5 also shows another embodiment of the present invention, in which the detent means of the bracket 10B is constituted by two through holes 19 for detent bolts (not shown).

[Effects of the Invention] Since the present invention is configured as described above, the narrow mounting surface of the first cross member having the large rivet fastening work hole is effectively used, and the structure is compact and simple. The front bumper can be attached to the first cross member with good workability.

Further, it is possible to increase the span of the mounting bolt to improve the support rigidity and also the support rigidity when a person rides on the front bumper.

Moreover, the first cross member can receive an impact force.
