Description

Description: TECHNICAL FIELD The present invention relates to a vehicle body structure on the engine room side of an automobile.

[Prior Art] Examples of this type of the related art include, for example, those shown in FIGS. FIG. 4 is a view of the front left side from the substantially central position on the rear side of the engine room E, and shows only the left side because it is symmetrical with respect to the engine room E. In the figure, reference numeral 1 denotes a hood ridge constituting a side wall of the engine room E, and a hood ridge reinforcement 2 is joined to the outside of the hood ridge 1 to form a closed cross section. Specifically, an upper flange portion 2a formed on the upper portion of the hood ridge reinforcement 2 is joined to an upper flange portion 1a of the hood ridge 1, and a lower flange portion 2b formed on a lower portion of the hood ridge reinforcement 2 is formed. Are joined to the vertical wall portion 1b of the hood ridge 1.

On the other hand, the hood ridge 1 is provided with a strut housing 3 at a predetermined position. The strut housing 3 includes a housing body 4 and a closing member 5 for closing an upper opening. This closing member 5
Is thicker than other parts in order to ensure strength against input from wheels. A reinforcing plate 6 for reinforcing the strut housing 3 is provided between the closing member 5 and the upper horizontal portion 1c of the hood ridge 1.

Examples of this type include, for example, Japanese Utility Model Laid-Open No. 62-3687.
There is the one described in Japanese Patent Publication No.

[Problems to be Solved by the Invention] However, in such a conventional vehicle body structure, the load acting on the closing member 5 of the strut housing 3 from the wheels is directed in a direction indicated by an arrow in FIG. Although a component force acts, since the upper flange portions 1a and 2a of the hood ridge 1 and the hood ridge reinforcement 2 are joined in a vertical plane, the component force acts in a peeling direction.
There is a risk that the strut housing 3 may fall inward, so that the steering stability and the sound and vibration performance are deteriorated. Therefore, there is a problem that these problems must be solved.

Means for Solving the Problems The present invention has been made in view of such conventional problems, and forms a closed cross section by joining a hood ridge reinforcement to the outside of a hood ridge forming a side wall of an engine room. In the vehicle body structure in which the strut housing is formed on the hood ridge, a flange portion is formed along the horizontal direction on the hood ridge reinforcement and spot-joined to each other, while closing an upper opening of a housing main body of the strut housing. A member is closed, a side end of the closing member is joined to a hood ridge, a rear end is extended rearward of the vehicle, and a rear end edge is joined to a dash lower panel vertical surface. It is characterized in that it has a vehicle body structure in which the component members overlap on the strut housing.

[Operation] According to such a means, the horizontal load applied to the strut housing can be supported in the shear direction by the flange portion along the horizontal direction on the hood ridge and the hood ridge reinforce, and is supported in the peeling direction. In comparison, we can support much more strongly.

Further, in the present application, since the rear end of the closing member is joined to the vertical plane of the dash lower panel extending in the vehicle width direction, the load applied to the strut housing can be dispersed throughout the dash lower panel. Not only can you
Since the load can be supported in the shearing direction, it is possible to reliably support the load.

In addition, in the present application, since the closing member and the flange portion overlap on the strut housing, even if the strut housing is inclined, these members interfere with each other and prevent deformation in this respect as well. You can do it.

[Examples] Hereinafter, the present invention will be described based on examples.

1 to 3 show an embodiment of the present invention. FIG. 1 shows the structure of the present application from the same depiction position as FIG. 4 presented as a conventional drawing.

First, the structure will be described. In the figure, reference numeral 11 denotes a hood ridge constituting a side wall of the engine room E.
Reference numeral 11 denotes an upper member 12 and a lower member 13.

As shown in FIG. 3, the upper member 12 and the lower member 13 are
The upper edge portion 13a is joined to the vertical wall portion 12a of the upper member 12.

A hood ridge reinforcement 15 having a substantially L-shaped cross section is joined to the upper member 12 to form a closed cross section along the vehicle longitudinal direction. Specifically, a horizontal flange portion 12b which is horizontally bent toward the engine room E is formed on an upper portion of the upper member 12.
A horizontal flange portion 15a formed on the upper portion of the hood ridge reinforcement 15 is spot-welded to 2b. Further, a vertical flange portion 12c extending in the vertical direction is formed at a lower portion of the upper member 12, and a vertical flange portion 15b of the hood ridge reinforcement 15 is spot-welded to the vertical flange portion 12c.

And the top part of this Food Ridge Reinforce 15
The upper part 16a of the front fender panel 16 is attached to 15c.

On the other hand, the strut housing 14
As shown in the figure, a housing body 17 and a closing member 18 for closing an upper opening of the housing body 17 are provided. Specifically, the closing member 18 has a plate thickness of about 2.3 mm and is formed to be thicker than the housing body 17 and the like. The closing member 18 has a support portion 18a for supporting a front suspension (not shown).
As shown in FIG. 1, a rear end horizontal surface of an extension portion 18b extending rearward from the dash lower panel 19 is joined to a horizontal surface 19a of the dash lower panel 19, and the rear end edge flange portion 1 of the extension portion 18b.
8c is also joined to the vertical surface 19b of the dash lower panel 19. As shown in FIG. 2, an outer flange portion 18d, which is a side end of the closing member 18, is joined to a vertical wall portion 12a of the upper member 12, and an engine room E of the closing member 18 is provided.
The side flange portion 18e is joined to the upper end edge portion 17a of the housing body 17.

The upper member 12 is attached to the support portion 18a of the closing member 18.
Horizontal flange 12 with hood ridge reinforcement 15
The b and 15a are joined so as to overlap on the strut housing 14.

Further, in the figure, reference numeral 20 denotes a front side member, and reference numeral 21 denotes a front side member.
Is a closing plate, both of which form a closed cross section, and are joined to the hood ridge 11 and the lower side of the housing body 1.

Next, the operation of the vehicle body structure having such a configuration will be described.

Support part 18a of closing member 18 from front suspension
When a load acts on the load, a component force acts on the load in the direction of the arrow in FIG. Then, this component is
Acts on the joint between the horizontal flange portion 12b of the upper member 12 and the horizontal flange 15a of the hood ridge reinforcement 15, but unlike the conventional case, since this joint surface runs along the horizontal direction, Since it acts as a shear force, the strength is improved.

In addition, since the extended portion 18b of the thick closing member 18 is joined to the dash lower panel 19, the load is borne by the dash lower panel 19 from the support portion 18a via the extended portion 18b.

Moreover, since the rear surface of the extension 18b of the closing member 18 is joined to the vertical surface 19b of the dash lower panel 19 extending in the vehicle width direction, the load applied to the strut housing 14 is applied to the entire dash lower panel 19. In addition to being able to disperse, these loads can be supported in the shear direction, so that a firm and firm support can be performed.

In addition, in the present application, since the closing member 18 and the horizontal flange portions 12b and 15a overlap on the strut housing 14, even if the strut housing 14 is inclined, Interference with the flanges 12b and 15a,
In this respect, deformation can be prevented.

Therefore, the steering stability and the sound vibration performance are improved by improving the inward falling rigidity of the strut housing 14.

[Effects of the Invention] As described above, according to the present invention, the horizontal flange portions of the hood ridge and the hood ridge reinforce are joined to each other, while the upper opening of the housing body of the strut housing is closed. With the member closed, the rear end of the member is extended rearward of the vehicle to join the rear edge to the dash lower panel. In addition, the closing member and the flange overlap on the strut housing. Therefore, even if the strut housing is inclined, these members interfere with each other, and the load in the inward falling direction is effectively loaded by the hood ridge reinforcement and the dash lower panel, so it is possible to improve the inward falling rigidity. And has a practically useful effect of improving steering stability and sound vibration performance.
