Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a trunk hinge in a vehicle.

[Conventional technology]

Generally, a trunk room provided at the rear of the vehicle interior is closed off by a trunk lid, which can be opened and closed by a trunk hinge provided between the trunk lid and the vehicle body.

Conventionally, as this type of trunk hinge mounting structure, the one shown in Figures 4 and 5 has been known (NISSAN Service Bulletin 1972).
October, No. 491 (Introduction of Bluebird U11 series cars). A trunk hinge 1 formed in a substantially U-shape is bridged between a vehicle body 2 and a trunk lid 3, and one end thereof is rotatably supported by a pin 6 on a rear waist portion 5 via a bracket 4. At the same time, the other end is fixed to the lower surface of the trunk lid 3 with a bolt 7. The rear waist portion 5 is formed into a closed cross-section structure by a flange connection of a rear parcel shelf 8 and a rain force 9 disposed on the lower side thereof, and the rear parcel shelf 8 is attached to the trunk hinge 1 at the location where it is attached to the trunk hinge 1. It is recessed, and a protruding hole 10 for the bracket 4 is formed in the bottom surface thereof. Furthermore, an insertion hole 11 for the trunk hinge 1 is formed in the reinforcement 9 at a portion corresponding to the protrusion hole 10 described above. The bracket 4 is formed into a substantially hat shape, and has a flange 12 at the lower periphery and pin insertion holes 13a and 13b on both sides. In FIG. 4, reference numeral 14 is a rear parcel trim that covers the upper surface of the rear parcel shelf 8, and 15 is a rear window panel.

In such a mounting structure, when assembling the trunk hinge 1, the bracket 4 is first aligned and then welded to the periphery of the insertion hole 11 of the reinforcement 9, and then the trunk hinge 1 is installed inside the bracket 4. Insert one end of the reinforcement 9 from below and insert it into the pin insertion holes 13a, 13 of the bracket 4.
After aligning with b, insert the pin 6 and support it rotatably. Next, temporarily tighten the other end of the trunk hinge 1 to the underside of the trunk lid 3 with bolts 7, and while opening and closing the trunk lid 3, move the temporary tightening position of the trunk hinge 1 to secure it between it and the rear fender panel. After the adjustment is completed, open the trunk lid 3 again and fully tighten the bolts 7 to complete the assembly.

[Problem that the invention attempts to solve]

By the way, in the conventional trunk hinge mounting structure, it is not possible to adjust the installation with the trunk lid 3 closed, which requires a lot of man-hours and is troublesome. This is to adjust the installation of the trunk lid 3 by adjusting the tightening position of the bolts 7 that fix the trunk lid 3 and the trunk hinge 1, so after temporarily tightening the bolts 7, the trunk lid 3 is closed and the rear fender panel is closed. If the installation position of the trunk lid 3 is incorrect, open the trunk lid 3, adjust the temporary tightening position of the bolt 7 of the trunk hinge 1, close the trunk lid 3 again, and adjust the position between it and the rear fender panel. This is because the work has to be repeated and the trunk lid 3 has to be opened and closed many times until it is in the proper position, which is cumbersome.

Therefore, the technical problem of the present invention is to simplify the work by making it possible to adjust the installation while the trunk lid is closed.

[Means for solving problems]

In order to solve the above technical problems, the present device provides a trunk hinge mounting structure in which a rear waist section with a closed cross-section is formed by joining a rear parcel shelf at the rear of the vehicle cabin to a reinforcement layer disposed on its underside, and a bracket is disposed on this rear waist section to rotatably support one end of a trunk hinge with a pin and fix the other end of the trunk hinge to the underside of the trunk lid. In this trunk hinge mounting structure, a bracket insertion hole is opened in the reinforcement and a recess is provided in the rear parcel shelf above the bracket insertion hole. On the other hand, the bracket is provided with a receiving surface which abuts against the back surface of the recess when it is disposed into the rear waist section from the bracket insertion hole and an engaging surface which abuts against the periphery of the bracket insertion hole from the outside, and fastening portions are provided between the recess and the receiving surface, and between the periphery of the bracket insertion hole and the engaging surface, which can secure each abutment surface from the outside of the rear waist section.

[Effect]

According to the above-mentioned means, a temporary tightening part for adjusting the installation of the trunk lid is provided between one end of the trunk hinge and the rear waist part, and this temporary tightening part can be adjusted from the outside. It is now possible to adjust the installation with the door closed.
