Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a front body structure of an automobile in which the outer shell of the front end of the automobile is constituted by a soft fascia made of a soft skin member. It is something.

(Prior Art) Recently, the outer shell of the front end of an automobile has been constructed of a soft skin member called a soft fascia in order to have a high degree of molding freedom or to reduce weight. Conventionally, in order to fix the upper end of such a soft fascia to the vehicle body, a retainer integrated with the soft fascia was attached to a radiator shroud such as a shroud assemblage, as shown in Japanese Utility Model Application No. 52-112045. This was done by fixing it to the member.

By the way, recently, from a design standpoint,
The front nose is required to project significantly further forward than the radiator shroud member; It will be placed. Therefore, in such a vehicle, when supporting the soft fascia by the means described in the above-mentioned publication, the retainer integrated with the soft fascia must be extended far to the rear of the vehicle body and attached to the radiator. Alternatively, a retainer on the radiator shroud member side that extends further forward than the radiator shroud member may be separately provided, and a retainer on the soft facia side may be attached to the retainer on the radiator shroud member side. Become.

However, in any of the above cases, the retainer will extend significantly in the longitudinal direction of the vehicle.
Problems will arise in terms of the support strength of the soft fascia. In other words, the weight of the soft fascia and the external force applied to its upper end are borne by the radiator shroud member via the elongated retainer supported in a cantilevered manner by the radiator shroud member. This poses a problem in that the retainer is easily bent and the attachment position of the soft fascia is greatly distorted.

(Object of the Invention) The present invention has been made in consideration of the above circumstances, and even when the soft fascia is located further forward than the radiator shroud member, the soft fascia can be To provide a front body structure for an automobile that can be securely attached to and supported by a vehicle body.

(Structure of the Invention) In order to achieve the above-mentioned object, the present invention has the following structure. In other words, it is a mounting structure for a soft fascia made of a soft skin member that covers the front of the vehicle body, and extends forward from a radiator shroud member that extends in the width direction of the vehicle to direct the running wind introduced from the front of the vehicle body to the radiator. A pair of left and right air guide side panels are provided for guiding, the lower ends of the pair of left and right air guide side panels are connected to the left and right side frames, and the lower ends of the pair of left and right air guide side panels are lower than the radiator shroud members of the pair of left and right air guide side panels. The upper end portions located at the front are connected to each other by a fascia set plate extending in the vehicle width direction, and the upper end portion of the soft fascia is supported by the fascia set plate.

With this configuration, in front of the radiator shroud member, there is a pair of left and right air guide side panels and a fascia set plate that connects the upper ends of the side panels, which increases the strength when viewed from the front of the vehicle body. An excellent gate-shaped (〓-shaped) structure is constructed,
The force applied to the soft fascia is firmly borne by the side frame through this portal structure.

In particular, if the soft fascia is positioned to protrude further forward than the radiator shroud member, the air guide side panel will also protrude considerably forward from the radiator shroud member, and the lateral direction of its upper front end will Although it becomes difficult to secure rigidity, sufficient lateral rigidity can be ensured by using the face set plate.

It is fixed to the front flange portions 5b of the pair of left and right fender brackets 5 using screws (screw holes for this purpose are shown as 24 in FIG. 2). The front end of the forward extending arm 4a of the apron reinforcement 4 is joined to the front flange 5b, thereby reinforcing the front flange 5b.

Although the embodiments have been described above, the present invention is not limited thereto, and includes, for example, the following cases.

Although the locking device 17 is provided at the connecting portion between the shroud upper 2 and the rear stay 15, the locking device 17 is installed at the middle portion of the face set plate 11 in the vehicle width direction (between the face set plate 11 and the front stay). 14), and in this case, the rear stay 15 can be omitted.

The upper front end of the fender bracket 5 is connected to the upper front end of the assembly of the wind guiding side panel 12 and the fascia set plate 11 via the reinforcing bracket 25, as shown by the dashed line in FIG. In this case, the reinforcing bracket 25 may be integrally molded with the face set plate 11. By doing this, not only the rigidity of the fender bracket 5 is improved, but also the retractable headlamp 20 is prevented from being damaged by the soft fascia 1 that tends to protrude and deform rearward in the event of a collision or the like. This can be prevented as much as possible.

The front stay 14 and the rear stay 15 may be integrally molded as shown by reference numeral 26 in FIG.

Facia set plate 11, wind guide side panel 12, cross member 13, and front and rear stays 1

(Effects of the Invention) As is clear from the above, the present invention has the following advantages:
The fascia set plate, which is placed in front of the radiator shroud member and to which the upper end of the soft fascia is attached, is supported by the side frame via a pair of left and right air guide side panels. Even when the soft fascia is positioned further forward than the radiator shroud member, the soft fascia can be securely fixed to the vehicle body.

In addition, since the pair of left and right wind guide side panels that guide the running air to the radiator are effectively used to support the fascia set plate, it is possible to separately provide a member specifically for supporting the fascia set plate. The number of parts can be reduced compared to the previous model.

Of course, the face set plate has a considerable length because it extends in the vehicle width direction and connects the pair of left and right wind guide side panels.
This makes it possible to support the soft facia over a wide area, which is also preferable from the viewpoint of supporting the soft facia, which is vulnerable to local forces.
