BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a bumper arranged at the front and rear of a frame-structured vehicle, particularly a bumper side mounting structure.

[0002]

2. Description of the Related Art Conventionally, bumpers arranged at the front and rear of a frame-structured vehicle, particularly the mounting structure at the bumper side, is a bumper side in which a body is mounted on a frame side end on which a body is mounted via bolts or the like. The bumper is held by the stay, and the bumper beam fixed to the frame is abutted against the bumper beam by the back bar which is integrated with the frame from the back surface direction, and in particular, the bumper side is prevented from resonating due to the vibration generated by the vehicle. Things are common.

[0003]

However, in the above-mentioned conventional one, the bumper is held by the bumper side stays which are fixed to the frame side end on which the body is mounted via the body mount damper by bolts or the like, and The bumper beam, which is fixed to the frame by the back bar that is integrated with the frame, is brought into contact with the rear side of the frame, and the bumper side is prevented from resonating due to the vibration generated by the vehicle. Since the bumper side stays are fixed to the frame on which the body is placed via the body mount damper so as to be movable in the vertical direction, it is possible to effectively prevent the bumper from resonating due to the vibration generated by the vehicle. , Bumper to prevent interference between the body and bumper If it is not possible to reliably control the position of the bumper side upper surface and the body and the vehicle width direction at the time of attachment, and if an effective gap cannot be established, due to the vertical movement of the frame and body when driving on rough road The bumper and the body may come into contact with each other to cause damage, or an excessive gap may be formed between the bumper and the body, which may impair the appearance.

Therefore, the present invention is intended to improve the drawbacks of the above-mentioned conventional ones, and suppresses the resonance of the bumper due to the vibration generated by the vehicle in accordance with the movable condition of the frame and the body, and when the bumper is mounted. It is possible to position the bumper side and the body in the up-down and left-right directions, and to limit the bottom abutment at the time of maximum relative displacement between the frame and the body.

[0005]

To this end, a slider bracket that holds one end of a swing slider roller movably in a slider rail joined to the body side in the vehicle front-rear direction and attaches the other end to the inside of the bumper side. It is joined to a slider arm provided on the outside of the slider bracket so that it can move up and down through a centering rubber fixed to the inside.

[0006]

With the above structure, when the bumper is assembled to the body, the swing sladder roller is fitted to the slider rail that is joined to the body side along the vehicle body direction, and then the back side of the bumper is pressed from the back side. Since it is attached by abutting the bumper beam that is fixed by the bar, it is possible to secure a sufficient gap with the body on the bumper side, and inside the slider rail so that the bumper can move in the front-back direction of the vehicle body. Since the swinging sladder roller is fitted, the shrinkage of the resin bumper after assembly due to the ambient temperature or the forward collision energy can be absorbed by sliding the swinging sladder roller in the slider rail.

Further, in the absorption of the relative displacement between the frame and the body, which is peculiar to the frame structure vehicle, one end of the swing sladder roller that connects the bumper and the body is screwed by a screw or the like into a slide arm as a fulcrum. By absorbing by rotating in the vertical direction and adjusting the alignment rubber, it is possible to prevent bottom bumping between the body and the upper surface of the bumper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention will be further described with reference to the embodiments shown in the drawings. (1) is a front part of a vehicle having a frame structure according to an embodiment of the present invention, and the front part (1) of the vehicle is
A resin bumper (4), which comprises a body (2) and a frame (3) that supports the body (2) via a body mount damper, and is integrally molded with resin.
Is integrally attached by abutting a bumper beam (5) fixed by a back bar (6) integrally fixed to the frame (3) from the back surface direction of the bumper (4). It is a thing.

Then, at the bumper side (7) of the bumper (4) supported by the back bar (6) fixed to the frame (3), a slider rail joined to the body side (8) along the vehicle body direction. The other end of the swinging slider roller (10), one end of which is movably held in (9), is held in the slider bracket (11), and through a centering rubber (12) having a bellows-shaped cross section, The slider arm (13) fixed on the inside of the bumper side (7) and fixed to the outside of the slider bracket (11) is screwed through the mounting hole (17) so as to be sandwiched by the screw (18) from the front-rear direction, The body side (8) and the bumper side (7) are integrally connected.

Since this invention has the above-mentioned structure, when the bumper (4) is assembled to the body (2),
After one end of the swing sladder roller (10) is fitted into the slider rail (9) that is joined to the body side (8) along the vehicle body direction, one end is attached to the frame (3) from the back surface direction of the bumper (4). Since the bumper beam (5) fixed by a back bar (6) for screwing and fixing is attached to the bumper beam (5), the body (2) at the bumper side (7) and the upper surface portion (14) of the bumper (5). ) Can be sufficiently positioned and secured.

Also, one end of the swing sladder roller (10) is installed in a slider rail (9) joined to the body side (8) along the vehicle body direction so that the bumper (4) can be moved in the vehicle longitudinal direction. Since it is inserted,
Shrinkage due to ambient temperature of the resin bumper (4) after assembly,
Alternatively, the forward collision energy can be reliably absorbed by sliding one end of the swing sladder roller (10) in the slider rail (9).

Further, the absorption of the relative displacement between the frame (3) and the body (2), which is peculiar to the frame structure vehicle, is performed by the swing sladder roller (10) integrally connecting the bumper (4) and the body (2). , A slider arm (13) whose other end is screwed by a screw (18) or the like
It can be absorbed by rotation in the vertical direction about the inner fulcrum, and by adjusting the bottom contact gap (17) of the alignment rubber (12), the relative relationship between the frame (3) and the body (2). It is possible to prevent bottom swing of the swinging sladder roller (10) due to displacement, and prevent interference between the bumper (4) and the body (2).

[0013]

As described above, in a vehicle having a frame structure, the workability of mounting the bumper can be first improved by attaching the bumper to the frame with the swing sladder roller that can rotate in the vertical direction. At the same time, it is possible to take a large stroke in the up and down direction by swinging sladder roller
Since the relative displacement between the frame and the body, which is peculiar to the frame-structured vehicle, can be surely absorbed, it has an excellent effect of preventing the interference between the body and the bumper.
