Abstract

A load bearing structure for a large-scale vehicle includes a base and a return unit. The base includes a mounting seat and a side-skirt connecting member which has a pivot portion pivoted to the mounting seat. The pivot portion includes a first contact portion, a second contact portion and a third contact portion, and under normal conditions, the first contact portion is abutted against the mounting seat. The return unit is located within the pivot portion and pivoted to the mounting seat to keep the side-skirt connecting member staying in the normal conditions. The third contact portion defines a second angle with respect to the top plate, which allows the side-skirt connecting member to pivot in a bidirectional manner when returning to its original position, so that collision between the mounting seat and the side-skirt connecting member can be prevented, and the fatigue problem is consequently solved.

Claims

1. A load bearing structure for a large-scale vehicle comprising:

a base with a mounting seat and a side-skirt connecting member, the side-skirt connecting member having a pivot portion pivoted to the mounting seat, the pivot portion including a first contact portion, a second contact portion and a third contact portion, and under normal conditions, the first contact portion is abutted against the mounting seat; and

a return unit located within the pivot portion and pivoted to the mounting seat to keep the side-skirt connecting member staying in the normal conditions.

2. The load bearing structure for the large-scale vehicle as claimed in claim 1, wherein the pivot portion includes an outer end surface and an inn end surface, the return unit includes an elastic member, a first restricting member, and a second restricting member, the first restricting member has a first abutting surface abutted against the outer end surface of the pivot portion, and the second restricting member has a second abutting surface abutted against the inner end surface of the pivot portion, the first abutting surface is formed with a first positioning rib to push against the mounting seat, and the second abutting surface is also formed with a second positioning rib to push against the mounting seat, and the elastic member is disposed between the first and second restricting members.

3. The load bearing structure for the large-scale vehicle as claimed in claim 2, wherein the mounting seat is formed by a top plate and a connecting portion formed on a bottom of the top plate, each of the first and second restricting members has two wings, the first and second positioning ribs are pushed against the bottom of the top plate.

4. The load bearing structure for the large-scale vehicle as claimed in claim 2, wherein the elastic member is a torsion spring biased between the first and second restricting members.

5. The load bearing structure for the large-scale vehicle as claimed in claim 1, wherein the second contact portion defines a first angle ranging from 30-50 degrees with respect to the top plate of the mounting seat, and the third contact portion defines a second angle ranging from 10-20 degrees with respect to the top plate of the mounting seat.

6. The load bearing structure for the large-scale vehicle as claimed in claim 5, wherein the first angle is 40 degrees, and the second angle is 15 degrees.
