Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a front body structure for an automobile that can improve assembly workability.

[Conventional technology]

As disclosed in Japanese Utility Model Application Publication No. 55-114772, for example, in the conventional front body structure of an automobile, an apron frame is provided at the upper side edge of the wheel house and runs vertically through the body. It is known that it has been extended to Additionally, this apron frame was integrally molded with the wheel apron that formed the side wall in front of the wheel house.

[Problem that the invention seeks to solve]

However, in the above conventional structure, the apron frame is
Extends from the upper side edge of the wheel house to the front of the vehicle body,
Moreover, since it is integrally molded with the wheel apron, it is a relatively large member. Therefore, the work of joining the apron frame and wheel apron to the wheel house involves joining large members together, which has the problem of poor assembly workability.

Therefore, instead of having a structure in which the apron frame and the wheel apron are integrally molded, it may be possible to create a structure in which the apron frame can be connected to the wheel house by itself, which is relatively easy to handle. However, in this case, the apron frame that extends to the front of the vehicle body is only joined at the upper side edge of the wheel house, so it cannot be firmly joined. Therefore, until the wheel apron is reinforced by joining, etc., it is difficult to move the member to which the apron frame and wheel house are joined, and it is still not possible to improve assembly workability. .

[Means for solving problems]

In order to solve the above problems, the front body structure of an automobile according to the present invention includes: a wheel house that covers the tires of the front wheels; an apron frame that runs longitudinally through the vehicle body and is provided at the upper side edge of the wheel house; In the front body structure of an automobile, the apron frame is curved downward from the upper side edge of the wheel house along the front side edge of the wheel house, and the wheel apron forms a side wall in front of the wheel house. The wheel apron is joined to the wheel house portion to form a wheel house portion, while the wheel apron is joined to the wheel house portion and has a front portion bent inward of the vehicle body to form a shroud panel.

[For production]

With the above configuration, the apron frame is relatively easy to handle because it is not integrally formed with the wheel apron, and the work of joining it to the wheel house is easy. Moreover, since the apron frame is curved along the wheel house, the apron frame and the wheel house can be firmly joined to form a wheel house portion. Therefore, since the wheel house portion can be handled as an integral member, work efficiency is improved.

On the other hand, since the wheel apron is not integrally molded with the apron frame, it is a relatively small member and can be easily joined to the wheel house. Further, since the apron frame is a small member, the front portion can be bent to integrally form the shroud panel. Therefore, the number of parts can be reduced, and the work of joining separate shroud panels can be eliminated.

Further, since the front portion of the wheel apron is bent, the wheel apron has sufficient strength even if the apron frame does not extend to the front portion of the vehicle body.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in FIGS. 1 and 4, the wheel house section 1 is composed of a wheel house 3 that covers the tires 2 of the front wheels, an apron frame 4 that is a frame that runs longitudinally through the vehicle body, and a front side frame 5. ing.

The apron frame 4 has a shape curved downward from the upper side edge 3a of the wheel house 3 along the front side edge 3b. This apron frame 4 is joined to the wheel house 3, and as shown in FIGS. 2 and 3,
A closed cross section 6 is formed over the entire length of the apron frame 4.

On the other hand, the front side frame 5 is curved outward from the vehicle body from the lower edge side portion 3C of the wheel house 3 along the lower edge front portion 3d, and further extends forward. This front side frame 5 has a wheel house 3
A closed cross section (not shown) extending from the rear end of the front side frame 5 to the outwardly curved portion 5a is formed.

In addition, near the lower edge front portion 1b of the wheel house 1 in the front side frame 5, a
A frame 10 having a U-shaped cross section is joined. Furthermore, in the outwardly curved portion 5a of the front side frame 5,
The lower end portion of the downwardly curved portion 4a of the apron frame 4 is joined.

A wheel apron 7 forming a side wall in front of the wheel house portion 1 is a lower curved portion 4a of the apron frame 4.
and the front portion 5b of the front side frame 5. The front part of this wheel apron 7 is bent inward to the vehicle body to form a shroud panel 8, and the upper part 9 is also bent inward to the vehicle body.

Further, the center side of the vehicle body of the shroud panel 8 is further bent toward the rear of the vehicle body, and a lower portion 8a of the bent portion is joined to the frame 10.

In the above configuration, since the apron frame 4 is not integrally formed with the wheel apron 7, it is relatively easy to handle, and the work of joining it to the wheel house 3 is easy.

Further, since the apron frame 4 has a curved shape extending from the upper side edge 3a of the wheel house 3 to the front side edge 3b, it is firmly joined to the wheel house 3 to form the wheel house portion l. . Therefore, when joining the front side frame 5, wheel apron 7, etc. to the wheel house part 1, the wheel house part 1 can be handled as an integral member, which improves work efficiency.

Moreover, since the apron frame 4 is joined along the wheel house 3, the rigidity of the wheel house portion 1 is high. Therefore, it is possible to easily ensure sufficient rigidity to bear the load transmitted from the road surface to the vehicle body via the tires.

On the other hand, since the wheel apron 7 is not integrally molded with the apron frame 4, it becomes a relatively small member, and work such as joining to the wheel house portion 1 is facilitated. Further, since the wheel apron 7 is a small member, the shroud panel 8 can be easily formed by bending the front part. Therefore, the work of joining the separate shroud panels 8 can be eliminated.

Moreover, by bending the front part of the wheel apron 7, sufficient strength can be provided even if the apron frame 4 does not extend to the front part of the vehicle body.

Further, since the position of the wheel apron 7 in the vehicle width direction on the vehicle body can be set near the outermost side of the apron frame 4, a large space can be secured inside the front body of the vehicle.

〔Effect of the invention〕

As described above, the front body structure of an automobile according to the present invention has the following features:
A front body structure for an automobile that includes a wheel house that covers the tires of the front wheels, an apron frame that runs lengthwise through the vehicle body and is provided at the upper side edge of the wheel house, and a wheel apron that forms a side wall in front of the wheel house. In this, the apron frame curves downward from the upper side edge of the wheel house along the front side edge and is joined to the wheel house to form a wheel house portion, while the wheel apron is connected to the wheel house portion. The shroud panel is formed by joining together and bending the front part toward the inside of the vehicle body.

As a result, the apron frame is relatively easy to handle because it is not integrally formed with the wheel apron, and the work of joining it to the wheel house is facilitated. Moreover, since the apron frame is curved along the wheel house, the apron frame and the wheel house can form a wheel house portion that is firmly joined. Therefore, the wheel house portion can be handled as an integral member, resulting in improved workability.

In addition, it is possible to easily ensure rigidity sufficient to bear the load transmitted from the road surface to the vehicle body via the tires.

On the other hand, since the wheel apron is not integrally molded with the apron frame, it becomes a relatively small member, which facilitates the work of joining it to the wheel house. Further, since the apron frame is a small member, the front portion can be bent to integrally form the shroud panel. Therefore, the number of parts can be reduced, and the work of joining separate shroud panels can be eliminated, which again has the effect of improving workability.

Furthermore, since the front portion of the wheel apron is bent, the wheel apron also has the effect of having sufficient strength even if the apron frame does not extend to the front portion of the vehicle body.

Furthermore, since the position of the wheel apron in the vehicle width direction on the vehicle body can be set near the outermost side of the apron frame, there is also the effect that the space inside the front vehicle body of the vehicle can be widened.
