Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to improvement of the rear body structure of vehicles such as automobiles.

[Conventional technology]

In order to increase the rigidity of the body structure of automobiles, etc., Japanese Utility Model Application No. 55-70372,
Various body structures have been proposed, as described in Japanese Utility Model Application No. 58-119468 and Japanese Utility Model Application Publication No. 56-87375.

By the way, in vehicle bodies, in order to increase body rigidity and reduce vibration noise,
The body structure has a bulging cylindrical spring support formed in the center of the gear wheel house inner, a coil spring inserted into this spring support, and the spring support and rear floor cross member connected via a brace. It has been adopted.

That is, as shown in FIGS. 3 and 4, a cylindrical spring support 12 is formed in a protruding manner at approximately the center of the rear wheel house inner 10,
A coil spring is installed in this spring support 12, and the spring support 12 is attached to the brace 1.
The body structure is connected to the rear floor cross member 16 via the cross member 4, thereby increasing body rigidity and reducing vibration and noise.

[Problem that the invention attempts to solve]

However, in the body structure shown in FIGS. 3 and 4, since the end of the brace 14 is fixed to a part of the side wall of the spring support 12, the load from the coil spring installed in the spring support 12 is spring support 1
2, the brace 14 is displaced in the direction shown by the arrow X as the spring support 12 is displaced, and when this displacement is large, the brace 14
was deformed, and it was not possible to sufficiently increase the rigidity of the body.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a rear body structure for a vehicle that can improve body rigidity.

[Means for solving problems]

In order to achieve the above object, the present invention provides a rear body of a vehicle in which a cylindrical spring support is formed in a bulging shape on the inner rear wheel house, and this spring support and a rear floor cross member are connected via a brace. The brace constitutes a frame that extends from the end of the rear floor cross member along the axial direction of the rear floor cross member to the side wall of the spring support, and the upper part of the brace extends to the upper part of the spring support, and the brace has a spring. Both sides of the support side sandwich both ends of the radial side walls of the spring support to form a continuous planar structure, and the upper part of the brace extends in a tapered shape with a gradually smaller diameter from the upper part of the spring support to the upper part of the rear floor cross member. The upper end portions are fixed to the spring support and the rear floor cross member, respectively.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

1 and 2 show the construction of a preferred embodiment of the present invention.

In this embodiment, as shown in FIGS. 1 and 2, the width of the brace 14 is widened, the width of the rear floor cross member 16 is widened, and the upper part of the brace 14 is extended to the upper part of the spring support 12. Both sides of the spring support side of the brace 14 sandwich both ends of the radial side walls of the spring support 12, and the upper part of the brace 14 is connected from the upper part of the spring support 12 to the rear floor cross member 1.
The brace 14 is formed into a tapered shape that gradually becomes smaller in diameter and extends to the upper part of the brace 14, and both ends of the brace 14 in the axial direction are fixed to the spring support 12 and the rear floor cross member 16 by welding, respectively. Since it is the same as that shown in FIGS. 3 and 4, the same or corresponding parts are given the same reference numerals and their explanation will be omitted.

That is, the brace 14 in this embodiment is
The frame body extends from the end of the rear floor cross member 16 along the axial direction of the rear floor cross member 16 to the side wall of the spring support 12, and the upper part of the brace extends to the upper part of the spring support. Both sides of the spring support 12 sandwich both ends of the radial side walls of the spring support 12 to form a continuous planar structure, and the upper part of the brace 14 extends in a tapered shape with the diameter gradually becoming smaller from the upper part of the spring support 12 to the upper part of the rear floor cross member 16. However, both axial ends of the brace 14 are fixed to the spring support 12 and the rear floor cross member 16, respectively.
Therefore, the load from the coil spring acts on the spring support 12, and this load is transferred to the brace 14.
Since it is received as a shear load, it is not deformed by the load, and the rigidity of the body can be improved.

[Effect of idea]

As explained above, according to the present invention, both sides of the brace on the spring support side sandwich both ends of the radial side walls of the spring support, and the upper part of the brace gradually becomes smaller in diameter from the upper part of the spring support to the upper part of the rear floor cross member. The brace is formed to extend in a tapered shape, and both ends of the brace in the axial direction are fixed to the spring support and the rear floor cross member, respectively, so that the load acting on the spring support is received by the brace as a shear load. An excellent effect of improving body rigidity can be obtained.
