Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mounting structure for a trunk lid of an automobile.

(Prior Art) A trunk room of an automobile is configured such that a trunk lid is attached via a hinge to the edge of an opening of the trunk room formed in the vehicle body, and the opening of the trunk room can be opened and closed by the trunk lid.

By the way, in the automobile manufacturing process, from the viewpoint of workability when attaching the trunk lid to the opening of the trunk compartment, predetermined hinges are assembled on the trunk lid with high accuracy in advance, and the hinges of the sub-assembled trunk lid are assembled in advance. It is supposed to be attached to a predetermined location on the vehicle body (for example, see Japanese Utility Model Publication No. 10371/1983).

(Problems to be Solved by the Invention) By the way, when assembling the trunk lid to the vehicle body, it is necessary to make fine adjustments in consideration of manufacturing errors and the like, and then assemble it in a predetermined position.

Possible methods for making this fine adjustment include using a long hole between the opening edge of the vehicle body and the mounting plate, and using a long hole between the stay and the trunk lid.

However, in the former case, after the hinge is attached to the vehicle body, the interior of the passenger compartment, such as a bar shell trim, is applied to cover the part where the hinge is attached to the vehicle body. If the trunk lid installation is to be adjusted at a dealer's repair shop after shipment from the factory, it is necessary to remove the interior parts, etc., and a large amount of man-hours are required for the adjustment. turn into.

In addition, with the latter method, adjustments can be made even after installing the bar shell trim, but in order to make adjustments when assembling the trunk lid to the vehicle body on the vehicle production line, it is necessary to close the trunk lid. When assembling, check the position, and if it is misaligned, open the trunk lid, adjust the position between the stay and the trunk lid, close the trunk lid again, and check the position when assembling to the optimal position. The process must be repeated many times until the assembly is completed, which significantly impairs mass productivity.

Furthermore, it may be possible to adopt a long hole structure between the opening edge of the trunk lid and the mounting plate and between the stay and the trunk lid so that both can be adjusted, but this does not allow the reference position to be adjusted. Since it is not fixed at all, the adjustment becomes complicated.

Under these circumstances, the present invention provides a trunk lid that allows the trunk lid to be efficiently assembled to the vehicle body during the manufacturing process, and that allows the installation of the trunk lid to be adjusted regardless of the interior of the passenger compartment or the like. The purpose is to provide a mounting structure for.

(Means for Solving the Problems) Therefore, in the present invention, a hinge having a stay pivotably supported on the mounting plate is attached to the opening edge of the automobile body through a mounting hole formed in the mounting plate. At the same time, a plurality of attachment holes are formed in the stay, and a trunk lid is attached to the stay through bolts inserted through the attachment holes, and the trunk lid is attached to the vehicle body. In the configuration in which the opening of the trunk room is closed so as to be openable and closable, either the mounting plate or the mounting hole at the opening edge of the vehicle body is formed as a long hole extending in the longitudinal direction of the vehicle,
One of the mounting holes of the stay is formed as a reference mounting hole approximately equal to the diameter of the bolt used, and the other two mounting holes are formed as elongated holes that are long in the longitudinal direction of the vehicle.

(Function) Therefore, before installing the trunk lid in the trunk compartment, when assembling the hinge to the trunk lid, use the reference mounting hole of the stay and one long hole to accurately connect the stay and trunk lid. It is only necessary to attach the stays and the trunk lid that can be assembled and accurately attached to the opening edge, and the trunk lid can be efficiently attached to the opening of the trunk room.

In addition, even if it becomes necessary to adjust the installation of interior parts, etc., the adjustment can be made at the joint between the trunk lid and the stay, rather than the position of the hinge on the vehicle body. , interior parts assembly can be easily adjusted later.

(Example) The embodiment shown in the figures will be described below.

Bolt 14. 15 is inserted through the mounting hole 11a.

1lb, 17a, and 17b have a long hole structure, and their positions can be adjusted. That is, the attachment hole 17a.

11b is formed into a long hole that is long in the longitudinal direction of the vehicle relative to the diameter of the bolt 14.15, while the mounting hole 17b,
The diameter a is approximately the same as the diameter of the bolt 14.15.

14n and 15n are mounting nuts, which are attached to the mounting plate 12. It is welded to the opening edge 17 in advance.

Then, as the manufacturing process progresses, after the hinge 6 is attached to a predetermined position on the vehicle body, interior decoration such as a parschel trim 16 shown in phantom lines is applied.

Thus, at the tip of the stay 7 configured to be swingable,
The trunk lid 5 is fixed by the following mounting structure.

That is, a plurality of through holes 21, 22, and 23 are formed at the tip of the stay 7, and in this case, three mounting holes are arranged in the longitudinal direction of the vehicle (the horizontal direction in FIG. 1).

One mounting hole 22 is a reference mounting hole having a circular cross section, and in this embodiment, the diameter is approximately equal to the outer diameter of a bolt 22b that passes through the inside for 1 m, so that there is no looseness.

The other two mounting holes 21 and 23 are elongated holes configured similarly, and these mounting holes 21, 22, 23
The bolts 21b and 23 are long in the direction in which they are lined up, that is, in the longitudinal direction of the vehicle, and in the width direction (perpendicular to the plane of the paper in Figure 1).
The dimensions are approximately the same as the outer diameter of b (not shown). A reference mounting hole 22 is provided in parallel near one of the two elongated holes.

On the other hand, each of these mounting holes 21 are provided on the trunk lid 5 side.
