Description

Description: 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 a synthetic resin. 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 is made of metal as described in, for example, Japanese Utility Model Application Laid-Open No. 58-61681.
In order to save fuel efficiency and durability, a part of the cowl portion is made of synthetic resin. For example,
Japanese Unexamined Patent Publication No. Hei 3-5284 discloses a vehicle body structure which aims to reduce the weight by forming an upper panel constituting a cowl upper surface and forming a part of the cowl upper panel joined to a dash upper panel with resin. Has been described. [0003] However, in the case of a conventional sheet metal as described in Japanese Utility Model Application Laid-Open No. 58-61681, restrictions on the processing surface in a complicated shape, coating, etc. Finishing is required, and there are problems in durability due to generation of rust, waterproofness, and strength. Further, in the cowl portion described in JP-A-3-5284, the weight of the cowl is reduced by adopting a synthetic resin for only a part of the cowl upper panel. It is pointed out that the contribution to weight reduction is low. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to solve these problems and to form the entire cowl portion with a synthetic resin. While reducing the weight, improving the durability,
Further, the present invention provides a front body structure of a vehicle which is excellent in strength and appearance design. [0005] In the front body structure of a vehicle according to the present invention, a windshield made of a synthetic resin and a substantially L-shaped cross section for supporting the front end of the windshield from the back side are provided. A front body structure of a vehicle in which a cowl portion is constituted by a bracket made of a synthetic resin, wherein a rear end surface of the bracket is fixed to a sheet metal vehicle body via a seal member and protrudes from a front end of the bracket. And the rear 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. In the front body structure of a vehicle according to the present invention, a windshield and a bracket for supporting the windshield are formed of a synthetic resin, and a rear end surface of the bracket is attached to a sheet-metal body via a seal member. The front end of the windshield that is fixed and protrudes 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 the strength and durability are improved, and further,
Excellent appearance design can be obtained. In addition, it has become possible to reduce the cost of a conventional sheet metal cowl requiring secondary processing and painting finish. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an entire configuration of a cowl portion showing an example of a front body structure of a vehicle according to the present invention, and FIG. 2 is a rear perspective view of an overall configuration of a bracket provided on the cowl portion of FIG. . In FIG. 1, a cowl portion 10 that 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. 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 face 11b of the bracket 11 is provided with a sealing member to form a vehicle body made of sheet metal (see FIG. 3). (Shown). FIG. 3 is a sectional view taken along line AA of FIG. 1 and shows details of a cowl portion which is a front body structure of the vehicle according to the present invention. In FIG. 3, the cowl portion 10 is made of a synthetic resin formed by injection molding, and
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 has a structure in which reinforcing ribs 11a are provided at appropriate intervals and reinforced. The bracket 11 and the windshield 1
2 can be formed by injection molding. The contact surface between the front of the bracket 11 and the front flat portion 12a of the windshield 12 is simply supported, joined by high frequency processing, heat welding, bonding with an adhesive, or screw fixing. It is also possible to integrate them. Waterproofness can be further improved by interposing a sheet material made of a foam on the contact surface. The rear end face 11b of the bracket 11 is fixed to a sheet metal body 14 via a sealing member 13 having a cushioning property. For the seal member 13, a closed-cell type synthetic rubber-based material having a cushioning property, or a synthetic rubber-based material is suitably used. A seal member 15 is provided at the tip 11c of the bracket 11. The seal member 15 has a U-shaped seal portion 15a and a seal portion 15a.
And a cylindrical seal portion 15b provided integrally above the seal member. The seal portion 15a is fitted into a front end portion 11c of the windshield projecting from the front end of the bracket 11, and the seal portion 15b comes into contact with a protrusion 16a provided on the back side of the panel hood 16. I have. Therefore, the waterproof treatment by the seal member 15 can prevent rainwater entering from the windshield 12 from entering the inside of the engine compartment. A rear end 12 b of the windshield 12 is fitted with a seal molding 18 fitted into a lower end of a windshield 17.
And is in a waterproofed state. As described above, by providing a cowl portion made of a synthetic resin to form a front vehicle body structure of a vehicle, the weight can be reduced to almost half that of a conventional cowl portion made of sheet metal. In addition, the cost can be greatly reduced as compared with the conventional sheet metal cowl portion. Further, the structure in which the windshield 12 is held by the bracket 11 provided with the reinforcing ribs 11a improves the rigidity of the windshield 12 against deformation,
Strength and durability can be ensured, and the degree of freedom of design has been expanded in terms of external design, making it possible to respond to diversification. According to the vehicle body front structure of the present invention, a windshield 12 made of synthetic resin and a windshield 12 are provided.
