Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to the front body structure of an automobile, and more specifically, the present invention relates to a front body structure of an automobile, and more specifically, a suspension is installed on the inner surface of a wheel apron that constitutes the front side wall of the vehicle body, for example, the side wall of the engine room. This invention relates to a front body structure of an automobile in which a tower is formed.

(Prior Art) In an automobile in which an engine room is formed on the front side wall of the vehicle body, for example, in front of the passenger compartment, the side wall of the engine room is constituted by a wheel apron. This wheel apron is made in 1987.
As shown in Japanese Patent No. 47576, a suspension tower portion is formed on the inner surface thereof.

(Problems to be Solved by the Invention) A wheel apron with such a configuration generally includes a vertical plate-shaped wheel apron wall, and a wheel arch that wraps around the tires formed inside the wall on the inside of the vehicle body, for example, on the engine room side. However, since this vertical plate-like wall part has a planar shape, its rigidity is low and it is easily deformed. However, since there is a high possibility that the front side wall of the vehicle body will receive an impact in the longitudinal direction due to a collision or the like, it is necessary to improve the rigidity so that deformation does not occur particularly due to an impact in the longitudinal direction.

In view of the above-mentioned circumstances, an object of the present invention is to provide a front body structure for an automobile that has side walls that are resistant to longitudinal impacts such as collisions.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the vehicle body front structure according to the present invention has a structure in which the upper part of the wheel apron wall that constitutes the front side wall of the vehicle body, such as the side wall of the engine room, is attached to the vehicle body. A suspension tower mounting recess that bulges outward is formed, and a recess that bulges outward from the vehicle body is formed in the wheel apron wall portion, continuing from the suspension tower mounting recess and extending from the recess to a shroud panel at the front of the vehicle body. It is characterized by the presence of

(Effects of the invention) As described above, in the front body structure of an automobile according to the invention, the suspension tower mounting recess formed in the upper part of the wheel apron wall is extended to the shroud panel, and as a result, the suspension tower mounting recess formed in the upper part of the wheel apron wall is extended to the shroud panel. A recess is formed extending rearward from the front end of the wall in the longitudinal direction of the vehicle body.

For this reason, the wheel apron wall has a bend in the left-right direction when viewed from the front of the vehicle, and compared to the conventional structure in which the wheel apron wall was formed as a flat surface, This improves strength against loads.

In general, there is a high possibility that a car body will receive impact in the front and back direction due to a collision, etc., so in order to reduce the deformation rate of the front side wall of the car body due to a collision etc., and to prevent deformation, it is possible to Having high rigidity is highly desirable in terms of vehicle body structure.

Furthermore, the structure of the present invention does not require any reinforcing members and can improve rigidity, which is advantageous in terms of the manufacturing process.

(Example) Hereinafter, an example of the front body structure of an automobile according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the front body structure of an automobile according to the present invention, and FIG. 2 is an enlarged view of the main part of FIG. 1.

In FIG. 1, reference numeral 1 designates a dash panel, and with this dash panel 1 as a boundary, the front part is an engine room A, and the rear part is a vehicle compartment B.

A pair of left and right wheel aprons 2 extend forward from the left and right end portions of the dash panel 1, respectively, and a shroud panel 3 is disposed at the front end portions of the wheel aprons 2. As a result, the engine room A is constituted by the dash panel 1, the left and right pair of wheel aprons 2, and the shroud panel 3.

The wheel apron 2 constituting the side wall of the engine room A includes a vertical plate-shaped wall portion 2a and the wall portion 2.
The wheel apron 2 includes a wheel arch portion 2b that bulges out toward the engine room A side from the wheel apron 2a, and a front frame 5 is joined to the wheel apron 2 directly below the wheel arch portion 2b. A notch (not shown) is formed at the top of the wheel arch portion 2b, and the suspension tower 6 is attached to the wheel arch portion 2b so as to cover this notch.
and the wheel apron wall portion 2a above the wheel arch portion 2b. This suspension tower 6 includes side wall members 6 joined to each other.
a and a top wall member 6b, and this top wall member 6b
The end portion 7 is fitted into a suspension tower mounting recess 8 formed in the upper part of the wheel apron wall portion 2a and expanding outward from the vehicle body, and is joined to the wheel apron 2 in the recess 8 as described above.

Furthermore, the wheel apron wall portion 2a includes:
Continuing from the suspension tower mounting recess 8, a recess 9 is formed that extends from the recess 8 to the shroud panel 3 located at the front of the vehicle body. Like the recess 8, this recess 9 also bulges outward from the vehicle body, and therefore, the recess 9 and the recess 8 are integrated and extend long in the longitudinal direction of the vehicle body.

FIG. 3 is a sectional view taken along the - line in FIG. 2. As is clear from this figure, the sunpension tower mounting recess 8 is formed by a part of the wheel apron wall 2a being inclined toward the outside of the vehicle body.
The end portion 7 is fitted into the recess 8 and is joined to the wheel apron wall 2a in the recess 8.

Further, FIG. 4 is a cross-sectional view taken along the - line in FIG. 2, and as is clear from this figure, the recess 8
The recess 9 formed on the front side of the wheel apron is formed by inclining a part of the wheel apron wall 2a outward at substantially the same angle as the recess 8.

In this embodiment, the harness 10 is effectively inserted through the recesses 8 and 9.

As in this embodiment, the shapes of two consecutive recesses may be different, but they may also be completely the same shape. Moreover, it is preferable that such recesses 8 and 9 are such that a continuous long recess is formed over the entire length of the wheel apron 2 in the front-rear direction. Further, such recesses 8 and 9 are preferably formed symmetrically on the right and left wheel aprons, respectively.
