Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a body structure that receives suspension input.

[Prior Art] As shown in FIGS. 4 to 6, a relatively thick suspension support 2 is superimposed on a wheel house inner 1 as a body-side mounting means for the upper part of a column of a column-type rear suspension. A structure in which overlapping parts are joined by spot welding is often adopted.
As shown in FIG. 6, the suspension support 2 supports a shock absorber 3 and a coil spring 4 via an upper support 5.

[Problems to be solved by the invention] However, in the conventional body structure configured as described above, as shown in FIG. The suspension support 2 and the wheel house inner 1 are connected through the support 5.
When the transmission is transmitted to the suspension support 2, wheel house inner 1 as shown in Fig.
is deformed as shown by the broken line. This is because the general surface 16 at the rear of the wheel house inner 1 has high rigidity, and this is where the deformation of the wheel house inner 1 begins. It is considered that the deformation is performed so that the deformation of is maximized.

However, the suspension support 2 has a high rigidity due to its thick wall and is not deformed in the same way as the wheel house inner 1. As a result, as shown in Fig. 5, the end of the suspension support 2 and the wheel house Inner 1 has peeled off and there is a space between the two.
A gap 6 occurs, and the sealer 7 filled in the joint between the end of the suspension support 2 and the inner wheel house 1 cracks. As a result, water, dust, etc. may enter the vehicle interior from between the end of the suspension support 2 and the wheel house inner 1, or the suspension support 2 may
There was a problem with rust forming on the edges.

The purpose of this invention was made in view of the problems mentioned above.
To provide a body structure which prevents peeling of the end portions of a wheel house inner and a suspension support, and prevents sealer cracking, etc.

[Means for solving the problem] In the body structure according to the present invention, the top surface of the suspension support that receives input from the suspension forms a flat plate, and the top surface of the suspension support that receives input from the suspension forms a flat plate. It is bent to form a vertical wall with a U-shaped horizontal cross section, and a vertical wall with a U-shaped horizontal cross section similar to the suspension support is also formed on the wheel house inner, and the suspension support is connected to the wheel house. In a body structure in which both vertical walls are connected to each other by being fitted into the inner wheel house from below, the wheel house inner and the suspension support are located below and near the lower edge of the joint between the vertical walls of the wheel house inner and the suspension support. The structure is such that a bead is formed in order to achieve the above-mentioned object.

[Example] The embodiment shown in the figures will be described below.

Fig. 1 is a perspective view of an automobile adopting the structure of the present invention seen from the rear, Fig. 2 is an enlarged perspective view of the part shown in Fig. 1, and Fig. 3 is a schematic configuration of Fig. 2 taken along the - line. It is a diagram. A suspension support 11 for supporting the shock absorber and coil spring on the body, and a space between the end of the suspension support 11 and the wheel house inner 10 are filled to prevent water, dust, etc. from entering the vehicle interior. The structure of the sealer 12 is the same as the conventional one.

This embodiment differs from the conventional example in that a bead 13 is formed on the inner wheel house 10, as shown in FIGS. 2 and 3. As shown in FIG. 3, the bead 13 is formed between the end portion 11a of the suspension support 11 and the highly rigid portion 10 of the rear general surface of the wheel house inner 10.
It is formed between a.

With the configuration in which the bead 13 is formed in this way, even if the wheel house inner 10 and the suspension support 11 are deformed as shown by the broken line under the uplift load F from the tire 14 (road surface), the starting end of the deformation is wheel house inner 10
Since the portion of the bead 13 is closer to the end of the suspension support 11 than the highly rigid portion 10a at the rear of the wheel house, deformation of the inner wheel house 10 is reduced, and deformation especially near the end of the suspension support 11 is reduced. It is greatly reduced.

As a result, the end of the suspension support 11 and the inner wheel house 10 move while remaining in close contact with each other, and the occurrence of gaps as in the conventional case can be prevented.

[Effect of the invention] As explained above, according to the body structure according to the invention, the top surface of the suspension support that receives input from the suspension forms a flat plate, and from the front end, rear end, and inner end of this flat plate, A vertical wall is bent downward to form a U-shaped horizontal cross section, and a vertical wall with a U-shaped horizontal cross section similar to the suspension support is also formed on the inner wheel house. In a body structure in which both vertical walls are connected to each other by being fitted into the wheel house inner from below, a portion of the wheel house inner and the suspension support that is located below the lower edge of the joint between the vertical walls of the wheel house inner and the suspension support and of the lower edge of the wheel house inner and the suspension support. Since the structure has a bead formed nearby, it is possible to reliably prevent separation between the wheel house inner and the end of the suspension support due to the uplift load of the suspension, thereby preventing sealer cracking and the associated damage. This provides various excellent effects such as preventing water from entering the vehicle interior.

Claims (1)

[Claim for Utility Model Registration] The top surface of the suspension support that receives input from the suspension forms a flat plate, and the flat plate is bent downward from the front end, rear end, and inner end to form a vertical U-shaped horizontal section. In addition to the wall, the inner wheel house also has a vertical wall with a U-shaped horizontal cross section, similar to the suspension support.
In a body structure in which the suspension support is fitted into the wheel house inner from below and both vertical walls are connected, below the lower edge of the joint between the vertical walls of the wheel house inner and the suspension support. The body structure is characterized in that a bead is formed near the lower edge.
