Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, and in particular to an installation structure of a door hinge. Background Art

[0002] The installation structure of the door hinge mainly includes a hinge reinforcement plate, a nut fixing seat, and a hinge mounting nut. Among them, the hinge reinforcement plate is used to provide a stable foundation for hinge installation, and a hinge mounting hole is opened on it. The nut fixing seat includes a fixing plate fixed on the hinge reinforcement plate, and a through hole corresponding to the hinge mounting hole is opened on the fixing plate, and the aperture of the through hole is larger than the aperture of the hinge mounting hole. The screw hole of the hinge mounting nut is aligned with the hinge mounting hole through the through hole, installed in the nut fixing seat, and can move parallel in the nut fixing seat.

[0003] However, the existing door hinge installation structure, such as the hinge reinforcement plate, is fixedly connected to the hinge by only one bolt. As a result, the bolt will not only bear a large pressure, but also the hinge will easily rotate when the bolt becomes loose, thereby failing to better ensure the stability of the hinge.

[0004] Therefore, it is very necessary to invent a mounting structure for a door hinge. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a door hinge installation structure adopting a technical solution: a door hinge installation structure, comprising a forged hinge, a T-shaped reinforcement plate and a bolt, wherein: an integrated reinforcement block is arranged on the transverse plate of the T-shaped reinforcement plate, and a threaded hole is penetrated between the transverse plate of the T-shaped reinforcement plate and the reinforcement block; the threaded hole on the T-shaped reinforcement plate is fixedly connected to the fixing hole on the forged hinge through the bolt;

[0006] Preferably, a positioning hole is provided on a side surface of the forged hinge connected to the vehicle body;

[0007] Preferably, a positioning column is fixedly mounted on the vertical plate of the T-shaped reinforcing plate, and one end of the positioning column passes through the vehicle body and is plugged in and out of the positioning hole.

[0008] Preferably, an integrated fixing plate is provided above the transverse plate of the T-shaped reinforcing plate, and the fixing plate is fixedly connected to the vehicle body.

[0009] Preferably, both ends of the T-shaped reinforcing plate transverse plate are respectively provided with an integrated fixing plate 2, and the fixing plate 2 is fixedly connected to the vehicle body.

[0010] Preferably, an integrated fixing plate three is provided on each side of the vertical plate of the T-shaped reinforcing plate, and the fixing plate three is fixedly connected to the vehicle body.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] The overall arrangement of the utility model can provide doubly supported for the forged hinge by means of the positioning column and the bolts when the forged hinge is installed on the vehicle body. This not only avoids the need for the bolts to bear greater pressure, but also prevents the forged hinge from rotating when the bolts become loose, thereby making the whole structure safer and more reliable.
