Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a bonnet support structure for an automobile.

(Prior Art) Generally, the engine room of a car is separated from the passenger compartment by a cowl as a body structure, and the opening of the cowl has a bonnet (also called engine hood) that can be opened and closed in the vertical direction. is provided. The cowl functions as a support for the windshield, wipers, etc. On the other hand, the bonnet is usually installed on both the left and right sides of the rear end of the cowl side of the engine room opening located at the front side of the vehicle body, and more specifically, on the upper surface of the cowl side upper panel on both sides of the vehicle body. By attaching a hinge member for pivoting the bonnet and pivotally supporting the rear end of the bonnet to the hinge member,
The bonnet is constructed so that it can be opened and closed in the vertical direction using its rear end as a fulcrum (see, for example, Japanese Utility Model Publication No. 127666/1983).

(Problems to be solved by the invention) For example, when adopting an open cowl type car body structure in which the dart upper member and the cowl front panel are separated, the cowl itself has an open cross-section structure. There is a drawback that it is difficult to use the cowl part as a part for ensuring vehicle body rigidity. Therefore, for example, when trying to support a windshield with a darts upper member, or when extending the front end of the darts upper member to support a wiper, ensuring the support rigidity is a particular problem. becomes.

Furthermore, according to the conventional bonnet mounting structure described above, the bonnet, which is quite heavy, is mainly supported by the hinge member mounting part, especially when the bonnet is opened, so a large weight is loaded on the hinge member mounting part. It turns out. Therefore, it is necessary to particularly improve the rigidity of the upper surface portion of the cowl side upper panel, which is the hinge member attachment portion. Therefore, as a countermeasure, for example, reinforcing the hinge member mounting portion of the cowl side upper panel with a reinforcement member is considered. Conventionally, such reinforcing means have generally been taken; Partial reinforcement such as a panel cannot sufficiently improve the surface rigidity of the mounting portion, and is inconvenient in that it is necessary to separately prepare a reinforcement panel.

(Means for Solving the Problems) The present invention was made for the purpose of solving the above problems, and includes a windshield support member that supports the windshield, and a lower side of the windshield support member In an open cowl type automobile, the cowl portion is constituted by a darts upper member located at the windshield supporting member and forming a closed cross-sectional structure with the windshield supporting member. The overlapping part of each member is extended to the front of the vehicle body for a predetermined length, and a wiper is provided in the extended part, while the left and right parts of the extended part are One of the members at both ends is located on the left and right sides of the dash upper and extends from the upper surface of the cowl side upper panel installed on both sides of the cowl part to the joint with the wheel apron reinforcement. and a hinge member for pivoting the bonnet is attached to the joint.

(Function) In the above means, first, the windshield support member is made into a closed cross-section structure consisting of the first dart upper member and the second dart upper member, thereby providing sufficient windshield support rigidity. At the same time, a wiper support portion is formed by extending the front end portions of the first dart upper member and the second dart upper member in an overlapping state, and On both sides, at least one of the first and second dart upper members is further extended to both sides so as to overlap the upper surface of the cowl side upper panel and reach the joint with the wheel apron reinforcement. After the parts are joined together, a hinge member for the bonnet pivot is attached to the overlapping part, thereby achieving sufficient rigidity of the vehicle body as a supporting part for the cowl part itself, and at the same time reinforcing the bonnet hinge attachment part. ing. Therefore, sufficient support rigidity for the windshield and wipers can be ensured, and at the same time,
The hinge member mounting portion is sufficiently reinforced by the extended high-rigidity windshield support member, and its surface rigidity is greatly improved.
