Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a hinge pin of a rear package tray trim that is attached to a rear package tray trim in order to rotatably and rotatably support a rear package tray trim attached to the rear part of a vehicle on a rear package side support portion.

[0002]

[Prior art]

 The hinge pin of the rear package tray trim has a strong pin portion to firmly support the rear package tray trim, and it must be firmly attached to the rear package tray trim. As shown in FIG. 12, a rectangular iron plate is bent into a U-shaped cross section, both ends of the U-shaped are bent outward to form horizontal portions (34), and the rear package tray is provided in each horizontal portion (34). On the U-shaped bottom (32) of the main body (31) provided with a plurality of locking claws (35) for attaching to the trim by burring, the length of the main body (31) is made of the same material as the main body (31). A round pipe (36) longer than this was fitted and the U-shaped bottom portion (32) and the round pipe (36) were firmly welded to each other. Also, some hinge pins were made of synthetic resin and were made in one piece.

[0003]

[Problems to be solved by the device]

 However, the hinge pin of the conventional rear package tray trim described above requires separate labor, a technique, and a cost because the body (31) and the round pipe (36) are welded separately. In addition, in order to obtain strength, welding is performed over the entire length of the U-shaped bottom portion (32) of the main body (31), which requires a long round pipe (36). There was a problem that it was expensive. In addition, there has always been a demand for weight reduction and cost reduction for vehicle parts. Further, the conventional hinge pin made of synthetic resin described above has a problem that it is expensive and its strength is weaker than that of the iron plate, and it takes time to firmly attach it to the base material of the rear package tray trim with rivets or the like. There was a problem.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention processes and molds one T-shaped iron plate consisting of a large rectangular plate portion and a small rectangular plate portion, and a cylindrical rod-shaped portion is small. The length of the plate is the only limit. In this way, materials can be saved, welding work can be saved, weight can be reduced, processes can be shortened, and labor and cost can be reduced.

[0005]

[Embodiment of device]

 The hinge pin of the rear package tray trim according to the present invention is formed by symmetrically bending a T-shaped iron plate composed of a large rectangular plate and a small rectangular plate into a U-shaped cross-section. Each part is bent outward to provide a horizontal part, and each of these horizontal parts is provided with a plurality of locking claws. The small plate part is bent into a ring-shaped cross-section according to the semi-circular cross-section of the U-shaped bottom part. A cylindrical bar-shaped part is formed, and the locking claws of the horizontal part are penetrated into the base material of the rear package tray trim (burring), the entire hinge pin is attached, and the bar-shaped part is completed when the rear package tray trim is completed. The rear package tray trim is detachably fitted to the support portion on the side of the rear package so that the rear package tray trim can be detachably and rotatably supported.

【Example】

 1 is a perspective view of a hinge pin of a rear package tray trim of the present invention, FIG. 2 is a plan view of the same, FIG. 3 is a front view of the same, and FIG. 4 is a hinge pin of the present invention. FIG. 5 is a partial perspective view of the rear package tray trim with the attached, and FIG. 5 is a partially enlarged side view of the same.

The hinge pin (1) of the rear package tray trim is attached to the end of the rear package tray trim (A) as shown in FIGS. Although not shown, this hinge pin (1) is detachably supported by a support portion on the rear package side, and this serves as a fulcrum to allow the rear package tray trim (A) to rotate.

The hinge pin (1) is made of a T-shaped cold-rolled steel plate (referred to as SPCC) composed of a large rectangular plate portion (2) and a small rectangular plate portion (3). The horizontal plate (4) is provided by bending the U-shaped section of the large plate (2) outward with a U-shaped cross section, and each of the horizontal parts (4) has a locking claw (5) called burring. A plurality of small plates are provided, and the small plate portion (3) is bent into a ring-shaped cross section according to the semicircular cross section of the U-shaped bottom to form a cylindrical rod-shaped portion (6).

The rod-shaped portion (6) is inserted into and removed from the support portion on the rear package side. The entire hinge pin (1) is fixed to the rear package tray trim (A) by inserting a plurality of locking claws (5) of the horizontal portion (4) into the base material of the rear package tray trim (A).

Next, the manufacturing process of the hinge pin (1) of the rear package tray trim will be outlined. 6 to 9 are explanatory views showing the manufacturing process. First, as shown in FIG. 6, the material of SPCC is shape-trimmed to form a T-shaped plate composed of a rectangular large plate portion (2) and a rectangular small plate portion (3). Cuts (3a) are made from both sides between the small plate part (3), and a plurality of pilot holes are formed in the portions to be the locking claws (5) at both ends of the large plate part (2). Then, as shown in FIG. 7, both sides of the small plate portion (3) are bent at 90 degrees. At the same time, the locking claw (5) of the part where the pilot hole was opened is made. However, the locking claw (5) has not been expanded yet.

Subsequently, as shown in FIG. 8, the small plate portion (3) is formed into a cylindrical rod-shaped portion (6). At the same time, open the locking claw (5). Finally, as shown in FIG. 9, both ends are bent in a U shape and horizontally bent outward to form a horizontal part (4), and the hinge pin (1) is completed. The cylindrical shape of the completed rod-shaped portion (6) has a ring-shaped cross section, and has a shape according to the semi-circular cross section of the U-shaped bottom.

[0012]

[Effect of device]

 The present invention is implemented in the form as described above, and has the following effects.

Unlike the conventional one that welds round pipes, only the small plate portion is formed into a cylindrical rod-like portion without welding, so material can be saved, welding labor can be saved, and weight can be reduced. It is possible to shorten the process, save labor, and reduce the material cost and the manufacturing cost.
