Description

[Detailed Description of the Invention] This invention relates to a lateral rod mounting structure for a vehicle body with improved reinforcement structure.

As shown in FIGS. 1 and 2, a lateral rod bracket a for attaching a lateral rod is generally provided near the joining portion of the rear side member b to the rear floor cross member c. This lateral rod bracket a is fixed to the lower surface of the rear side member b. Therefore, the offset d between the input point of the lateral rod bracket a and the rear side member b becomes large, and the rigidity of the lateral rod bracket a becomes small.

Therefore, the thickness of the lateral rod bracket (a) is increased to increase its strength, and a lateral rod reinforcement hose (e) is provided for reinforcement. However, the lateral rod rain hose e has a structure in which one end of a plate-shaped body is fixed to the lateral rod bracket a and the other end is fixed to the rear floor cross member c, and the offset d has to be reduced. It is not possible to increase the strength sufficiently.
Furthermore, the increased wall thickness of the lateral rod bracket a and the lateral rod reinforcement hose e causes an increase in weight.

This idea was devised by paying attention to the above-mentioned circumstances, and its purpose is to spread the input by connecting and fixing the lateral rod drain hose to the side wall and bottom wall of the spare tire well, and also to spread out the input force by fixing the lateral rod drain hose to the side wall and bottom wall of the spare tire well. To provide a vehicle body structure of a lateral rod attachment part which can reduce offset by lowering the input point of the lateral rod bracket, increase rigidity, and reduce the weight of the lateral rod bracket and reinforcement.

This invention will be explained below based on an embodiment shown in the drawings. Reference numerals 1 and 1 in FIGS. 3 to 6 are rear side members of the vehicle body, and a rear floor cross member 2 is installed between these members. Rear side members 1, 1 and rear floor cross member 2
has a U-shaped cross section with an open upper surface, and flanges 3 at both ends of the rear floor cross member 2 are welded and fixed to the side walls of the rear side members 1, 1. The openings of the rear side members 1 and 1 and the rear floor cross member 2 are closed by a rear floor 4, and a spare tire well 5 is provided between the rear side members 1 and 1. Furthermore, a lateral rod bracket 6 is fixed to the lower surface of the rear side member 1 located in the vicinity of the connecting portion 1a between the rear side member 1 and the rear floor cross member 2. The lateral rod bracket 6 is formed by bending a plate into a U-shape.
is fixed to the side. A mounting hole 9 is bored in the lower end of the lateral rod bracket 6, into which a lateral rod (not shown) is mounted. Furthermore, a lateral rod drain hose 10 is attached to the lateral rod bracket 6.
One end of is fixed. This lateral rod drain hose 10 has a metal plate with one end bent into a U-shape and the other end curved into an arc. Spot welded. Further, the arcuate portion 12 is spot-welded to the bent portion 2a of the rear floor cross member 2 together with the spare tire well 5, and is joined along the side wall 5a and bottom wall 5b of the spare tire well 5.
It is fixed by spot welding. and,
This joint fixing portion 13 reduces the offset h with respect to the input point of the lateral rod bracket 6 by deepening the spare tire well 5.

Therefore, the external force applied to the input point of the lateral rod bracket 6 is
0 to the spare tire well 5 through the joint fixing part 13, and since the joint fixing part 13 is located below the input point of the lateral rod bracket 6 to reduce the offset, The strength of the lateral rod bracket 6 can be improved.

As explained above, according to this invention, the strength of the lateral rod bracket can be improved without increasing the wall thickness, and the lateral rod reinforcement hose can be made thinner, so the bracket and reinforcement This has the effect of making it possible to reduce the weight.
