Abstract

PURPOSE:To obtain a small-sized and thin bracket for tie down and improve the rigidity of an installation part by superposing the extension part of a cross member joined with a side sill, onto the bracket for tie down which is superposed onto the horizontal part of a side member. CONSTITUTION:A bracket 3 for tie down is superposed onto the horizontal part 1a of a side member 1 arranged inside a side sill 6. In this installation structure, the horizontal part 2a of a cross member 2 joined with the side member 1 is extended, and an extension part 7 is joined with a side sill 6, and superposed onto the horizontal part 1a of the side member 1 onto which the bracket 3 for tie down is superposed. Each tie down hole 4b, 4c which coincides with the tie down hole 4a of the bracket 3 for tie down is opened on the horizontal part 1a of the side member 1 and the extension part 7 of the cross member 2. Therefore, the bracket 3 for tie down is made small-sized and thin, and the rigidity of the installation part can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for a tie-down bracket for an automobile.

[Prior art]

An example of a conventional structure for attaching a tie-down bracket in an automobile is shown in Fig. 4 (Japanese Unexamined Patent Publication No. 6
(See Publication No. 2-23877).

That is, in this figure, 1 is a rear side member fixedly attached to the lower surface of a rear floor panel (not shown) forming the floor surface of the rear cabin of the vehicle body and arranged in the front-rear direction of the vehicle body, and 2 is a rear side member having an angular shape in longitudinal section. Similarly, the rear cross member is a strength member fixed to the lower surface of the rear floor panel and arranged in the vehicle width direction, and has a cross-section shaped like a cross. These rear side members 1 and rear cross member 2 are connected to the horizontal part of the rear cross member 2. End flange 2a+ of 2a and horizontal portion 1a of rear side member 1
The end flange 2b+ of the vertical portion 2b of the rear cross member 2 overlaps with the vertical portion 1b of the side member 1 and is joined by spot welding W2. 3 is a tie-down bracket having a tie-down hole 4a, which is attached to the horizontal part 1 of the rear side member l.
The end vertical flange 3b overlaps the vertical portion 1b of the rear side member 1 and is spot welded W to the rear cross member 2 at the point a. A tie-down hole 4b that matches the tie-down hole 4a is provided in the horizontal portion 1a of the rear side member 1.

Note that FR indicates the front of the vehicle.

However, when using the attachment part of the tie-down bracket as a lever, it is necessary to attach it to the end of a rope moored to the floor of a transport vehicle or ship carrying a vehicle equipped with the tie-down bracket attachment structure. Hole 4a for tie-down the die-down hook.

4b, thereby preventing cargo from shifting on the loaded vehicle.

[Problem to be solved by the invention]

However, in such a conventional structure, there was a problem that the tie-down bracket 3 had to be larger in shape and thicker in order to improve its durability.

The present invention was made in view of such conventional problems,
By making the tie-down bracket smaller and thinner,
Another object of the present invention is to provide a mounting structure for a tie-down bracket for an automobile that is advantageous in side collisions.

[Means to solve the problem]

In order to achieve such an object, the present invention provides a structure for attaching a tie-down bracket in which a tie-down bracket is superimposed on a horizontal part of a side member, in which the horizontal part of a cross member connected to the side member is extended, and the horizontal part of the cross member connected to the side member is extended. the tie-down bracket is joined to the side sill, and the tie-down bracket is overlapped with the horizontal part of the overlaid side member;
Tie-down holes that match the tie-down holes of the tie-down bracket are provided in the horizontal portions of the side members and the extended portions of the cross members.

[For production]

Since the extension portion of the cross member coupled to the side sill further overlaps the tie-down bracket that overlaps the horizontal portion of the side member, the rigidity of the attachment portion of the tie-down bracket is improved. Furthermore, as a result of the presence of the extension of the cross member connected to the side sill, the strength of the vehicle side portion is increased.

〔Example〕

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

Note that the same parts as in the conventional example are given the same reference numerals.

In FIGS. 1 and 2, l denotes a rear side member having an angular shape in longitudinal section, which is fixed to the lower surface of the rear floor panel 4 that forms the floor surface of the rear compartment of the vehicle body, and is arranged in the longitudinal direction of the vehicle body;
Reference numeral 2 designates a rear cross member which is a strength member fixedly attached to the lower surface of the rear floor panel 4 and arranged in the vehicle width direction, and which has an angular cross-section. An end flange 2b of the vertical portion 2b of the rear side member 1 overlaps with the vertical portion 1b of the rear side member 1 and is connected to the vertical portion 1b by spot welding Wt. The connecting portion of the rear cross member 2 to the rear side member 1 is the front portion of the rear side member 1.

The end of the horizontal portion 2a of the rear cross member 2 is extended to the inner panel 6a of the side sill 6, which is a finger member attached to the end in the vehicle width direction, and the end flange 7a of the extension portion 7 is connected to the rear side. End flange la in horizontal portion 1a of member 1.

It is also coupled to the inner panel 6a by spot welding W4. Reference numeral 3 denotes a tie-down bracket having a tie-down hole 4a, which overlaps the front part of the horizontal part 1a of the rear side member 1 where it butts against the rear cross member 2, and has a vertical flange 3b at the end thereof. The vertical portion 1b is overlaid and spot welded W.

The horizontal portion 1a of the rear side member 1 and the extension portion 7 that overlaps the horizontal portion 1a are provided with tie-down holes 4b and 4c that match the tie-down holes 4a into which tie-down hooks (not shown) are engaged. There is.

FR indicates the front of the vehicle.

Note that a side end of the rear floor panel 4 is coupled to the side sill inner panel 6a.

With this configuration, the tie-down bracket 3 superimposed on the horizontal portion 1a of the rear side member 1 has an extension portion 7 of the rear cross member 2 connected to the side sill inner panel 6a.
is further polymerized, so the rigidity of the attachment part of the tie-down bracket is significantly improved. Therefore, the tie-down bracket 3 can be made smaller and thinner.

Furthermore, as a result of the presence of the extension portion 7 of the rear cross member 2 connected to the side sill inner panel 6a, the strength of the vehicle side portion is also increased, which is advantageous in side collisions.

〔effect〕

As explained above, according to the present invention, in the tie-down bracket attachment structure in which the tie-down bracket is superimposed on the horizontal part of the side member, the horizontal part of the cross member connected to the side member is extended. , the extension portion is coupled to the side sill, the tie-down bracket is superimposed on the horizontal portion of the overlapping side member, and the tie-down bracket of the tie-down bracket is attached to the horizontal portion of the side member and the extension portion of the cross member. Since the tie-down hole is provided to match the tie-down hole, the tie-down bracket can be made smaller and thinner, which is also advantageous in side collisions.
