Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body structure of a vehicle provided with a cowl portion made of synthetic resin.

[0002]

2. Description of the Related Art Conventionally, a cowl portion for taking in air for air conditioning is provided between a hood (panel hood) at a front portion of a vehicle and a lower end of a windshield. The cowl portion was made of metal, as described in Japanese Utility Model Laid-Open No. 58-61681, for example.
From the viewpoint of saving fuel consumption and durability, a part made of synthetic resin has been adopted for the cowl part. For example,
Japanese Unexamined Patent Publication No. 3-5284 discloses a vehicle body structure for the purpose of reducing the weight by forming an upper panel that constitutes the upper surface of the cowl and a part of the cowl upper panel joined to the dash upper panel from resin to reduce the weight. Has been described.

[0003]

However, in the case of a conventional sheet metal product as described in Japanese Utility Model Laid-Open No. 58-61681, restrictions on the machining surface in a complicated shape and finish processing by painting. However, there is a problem of durability due to the generation of rust, a problem of strength in addition to waterproofness. Further, in the cowl portion described in JP-A-3-5284, the weight is reduced by adopting a synthetic resin for only a part of the cowl upper panel, which is a very small portion when viewed from the whole cowl, It is pointed out that the contribution to weight reduction is low.

The present invention has been made in view of the above problems, and an object of the present invention is to solve these problems and form the entire cowl portion with a synthetic resin, While reducing the weight of, improved durability,
Further, the invention provides a front body structure of a vehicle which is excellent in strength and appearance.

[0005]

In a vehicle body structure for a vehicle according to the present invention, a windshield made of synthetic resin and a synthetic resin having a substantially L-shaped cross section for supporting the tip of the windshield from the back side are used. A front body structure of a vehicle in which a cowl portion is constituted by a bracket, and a rear end surface of the bracket is fixed to a sheet metal body through a seal member, and a front end portion of a windshield protruding from a front end of the bracket. The back side of the panel hood is waterproofed by a seal member, and the rear end of the windshield is in contact with a seal molding fitted along the lower end of the windshield.

[0006]

In the vehicle body structure of the vehicle according to the present invention, the windshield and the bracket for supporting the windshield are made of synthetic resin, and the rear end surface of the bracket is fixed to the sheet metal body through the seal member. The tip of the windshield protruding from the front end of the bracket and the back side of the panel hood are waterproofed by a seal member,
Furthermore, since the rear end of the windshield is in contact with the seal molding fitted along the lower end of the windshield, the weight and weight are improved, and the strength and durability are improved.
The appearance and design can be excellent. In addition, the cost can be reduced compared to the conventional sheet metal cowl that requires secondary processing and painting finish.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an overall configuration of a cowl portion showing an example of a front body structure of a vehicle of the present invention, and FIG. 2 is a rear perspective view of the overall configuration of a bracket provided in the cowl portion of FIG. . In FIG. 1, a cowl portion 10, which is a front body structure of a vehicle, includes a bracket 11 and the bracket 11.
And a windshield 12 supported from the back side. Also, the windshield 12 is
As shown in FIG. 2, the bracket 11 has a substantially L-shaped cross section.
The bracket 11 is integrally provided with reinforcing ribs 11a at appropriate intervals, and the rear end surface 11b of the bracket 11 is provided with a sheet metal body (see FIG. 3) via a seal member. (Shown).

FIG. 3 is a sectional view taken along the line AA of FIG. 1 and shows the details of the cowl portion which is the front body structure of the vehicle of the present invention. In FIG. 3, the cowl portion 10 is made of a synthetic resin molded by injection molding, and has a windshield 1
2 and a bracket 11 having a substantially L-shaped cross section for supporting the front flat portion 12a of the windshield 12 from the back side.
The bracket 11 is provided with reinforcing ribs 11a at appropriate intervals so as to be reinforced.

The bracket 11 and the windshield 1
Both 2 can be molded by injection molding. In addition, the contact surface between the front of the bracket 11 and the front flat portion 12a of the windshield 12 is not simply supported, but is also heat-welded by high-frequency machining, bonded by an adhesive material, or joined by screw fixing. It is also possible to integrate them into one. By interposing a sheet material made of foam on the contact surface, the waterproof property can be further improved.

The rear end surface 11b of the bracket 11 is fixed to a sheet metal vehicle body 14 via a cushioning seal member 13. For the seal member 13, a closed-cell type synthetic rubber-based material having a cushioning property or a synthetic rubber-based material is preferably used.

A seal member 15 is provided at the tip 11c of the bracket 11, and the seal member 15 has a seal portion 15a having a U-shaped cross section and the seal portion 15a.
And a cylindrical seal portion 15b which is integrally provided above. The seal portion 15a is fitted into the tip portion 11c of the windshield protruding from the front end of the bracket 11, and the seal portion 15b comes into contact with the protrusion portion 16a provided on the back side of the panel hood 16. There is. Therefore, the waterproof treatment by the sealing member 15 can prevent rainwater entering from the windshield 12 from entering the engine compartment.

The rear end 12b of the windshield 12 has a seal molding 18 fitted in the lower end of the windshield 17.
It is brought into contact with and is waterproofed.

As described above, by providing the cowl portion made of the synthetic resin to form the front body structure of the vehicle, the weight can be almost halved compared to the conventional sheet metal cowl portion. Also, in terms of cost, it is possible to reduce the cost to a large extent compared to the conventional sheet metal cowl portion. Further, due to the structure in which the windshield 12 is held by the bracket 11 provided with the reinforcing ribs 11a, the rigidity against deformation of the windshield 12 is improved,
It is possible to secure strength and durability, expand the degree of freedom in design in terms of appearance and design, and respond to diversification.

[0014]

In the vehicle body structure of the vehicle according to the present invention, the windshield and the bracket for supporting the windshield are made of synthetic resin, and the rear end surface of the bracket is fixed to the sheet metal body through the seal member. Is
The front end of the windshield protruding from the front end of the bracket and the back side of the panel hood were waterproofed by a seal member, and the rear end of the windshield was abutted against a seal molding fitted along the lower edge of the windshield. By adopting the front body structure of the vehicle with the cowl portion made of synthetic resin, the weight can be almost halved compared to the conventional cowl portion made of sheet metal. Also in terms of cost,
Compared to the conventional sheet metal cowl, it can be greatly reduced. In addition, the reinforcing effect of the bracket makes it possible to improve rigidity against deformation, ensure strength and durability, expand the degree of freedom in design in terms of external design, and respond to diversification. Therefore, it is preferably used as a front body structure of a vehicle.
