Abstract

PURPOSE:To prevent the reduction of the torque due to the creep through the lapse of time of an inner panel made of synthetic resin by installing a reinforcement onto the inner panel and directly installing a hinge member which supports an opening/closing body in opening/closing manners onto the reinforcement. CONSTITUTION:A hinge member 31 is directly installed by the tightening of a bolt member 33 and a nut member 22 onto the undersurface of a reinforcement 12 whose right and left side edge parts are installed at the rear edge position at the side edge part on the upper surface of an inner panel 3 made of synthetic resin by the fixing by rivets 13 and the adhesion by an adhesive 6. Therefore, the inner panel 3 is prevented from being interposed between the reinforcement 12 and the hinge member 31, and the reduction of the torque between the reinforcement 12 and the hinge member 31 which is generated by the creep through the lapse of time of the inner panel 3 made of synthetic resin is surely prevented.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to the structure of a vehicle opening/closing body such as a hood.

(Prior art) Generally, the opening/closing body of such vehicles is made of metal, but recently, in order to reduce the weight of the vehicle, the opening/closing body is made of synthetic resin such as plastic. There are some things. As disclosed in Japanese Utility Model Application Publication No. 60-165267, the structure of the opening/closing body of such a vehicle made of resin is provided with a plurality of ribs on the entire inner surface of the opening/closing body. At the attachment portion of the hinge member that supports the hinge member so as to be openable and closable, the distribution density is increased to increase the rigidity and strength of the attachment portion.

Further, as a vehicle opening/closing body structure different from the above-mentioned one, there is one in which at least the inner panel of the opening/closing body consisting of an inner panel and an outer panel is made of synthetic resin. In this case, a reinforcement is attached to the inner surface of the inner panel where the attachment part of the hinge member is located (between the inner panel and the outer panel), and the hinge member is attached to this reinforcement with the inner panel in between. ing.

(Problem to be Solved by the Invention) However, in the case where the opening/closing body is composed of an inner panel and an outer panel as described above, the synthetic resin inner panel sandwiched between the reinforcement and the hinge member has no rain. Since a fastening force is applied to connect the forcement and the hinge member, this fastening force causes creep in the inner panel over time, causing a decrease in the fastening force between the reinforcement and the hinge member, or a reduction in torque. There's a problem.

Therefore, it may be possible to interpose a smoother that approximately matches the wall thickness of the inner panel between the reinforcement and the hinge member to prevent torque reduction due to creep of the synthetic resin inner panel over time. .

However, considering the deformation of the inner panel due to the fastening force between the reinforcement and the hinge member, that is, the shrinkage of the wall thickness of the inner panel, it is difficult to select a smoother with an accuracy that approximately matches the wall thickness dimension. Even if the spacer is interposed between the reinforcement and the hinge member, the spacer becomes a separate member, which causes new problems such as loosening between the reinforcement and the hinge member. Therefore, providing a spacer in this way cannot be an effective solution.

The present invention has been made in view of these points, and an object of the present invention is to provide a structure in which the inner panel is not interposed between the reinforcement and the hinge member, so that the inner panel made of synthetic resin can be improved over time. This is to reliably prevent torque down due to creep.

(Means for Solving the Problem) In order to achieve the above object, the invention according to claim (1) takes measures such that at least the inner panel of the opening/closing body consisting of an inner panel and an outer panel is formed of synthetic resin. This assumes the opening/closing body structure of a vehicle. A reinforcement is attached to the inner panel, and a hinge member for supporting the opening/closing body so as to be openable and closable is directly attached to the reinforcement.

Moreover, the means taken in claim (2) is such that the reinforcement is provided between the inner panel and the outer panel, and the opening/closing body is provided with an opening into which the hinge member is inserted.

(Function) With the above configuration, in the invention according to claim (1), the hinge member is directly attached to the reinforcement attached to the inner panel made of resin, so the reinforcement and the hinge member are This eliminates the need for a spacer as a solution to the torque reduction caused by the creep of the inner panel over time, and reduces the reinforcement caused by the creep of the synthetic resin inner panel over time. Torque down between the ment and the hinge member is reliably prevented.

Further, in the invention according to claim (2), the reinforcement is inserted into the reinforcement provided between the inner panel and the outer panel (inside the opening/closing body) through the opening provided in the opening/closing body (inner panel and outer panel). Since the hinge member is directly attached, fastening members such as bolts and nuts that attach (fasten) the reinforcement and the hinge member are installed inside the opening/closing body, and the fastening members do not get in the way when the opening/closing body is opened. In addition, the fastening member is hidden within the opening/closing body and has a good appearance.
