Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge member for a vehicle, for example, which hinges the back door of a batch-back type automobile or the like so that it can be freely opened and closed.

In general, this type of automobile back door hinge member, especially the hinge member that is exposed and attached to the roof surface of the vehicle body, supports a relatively heavy back door so that it can be opened and closed, so it has a strong structure. In addition, in order to improve the appearance, a design that matches the shape of the vehicle body is required.

In the past, this type of vehicle hinge member was usually made of die-cast aluminum in order to meet the above-mentioned strength and design requirements, which led to inconveniences such as extremely high cost. there were.

Therefore, the present invention attempts to solve the above-mentioned conventional drawbacks by forming the hinge member from a sheet metal.

Hereinafter, the present invention will be explained based on an illustrated embodiment.
In the figure, reference numeral 1 denotes a pair of hinge members that are hinged to open and close the back door of, for example, a batch-back type automobile.Hinge 2 is fixed to the vehicle body side, and hinge 3 is fixed to the back door side.
It has a configuration in which these are connected by a shaft 4.

The fixed hinge 2 is formed by bending a sheet metal with a part opened in a U-shaped cross section as shown in the figure, while the movable hinge 3 is formed by bending a sheet metal into a cross-sectional shape,
In addition, the entire exposed surface is formed into a smooth curved surface, and the edge portion of the sheet metal is bent inward so as to be hidden in the shadow portion that serves as the mounting surface.

Mounting plates 5 and 6 are welded and fixed to the shadow parts (mounting surfaces on the back side) of both hinges 2 and 3, respectively, in order to fill the gaps 2b and 3b between the bent ends 2a and 3a, respectively. The hinges 2 and 3 are designed to have a closed cross-sectional shape to increase structural strength, and bolts 7 and 8, which are inserted and tightened into the vehicle body and the back door, are attached to the mounting plates 5 and 6 at the respective bent positions. The ends 2a and 3a are welded and fixed so as to protrude through gaps 2b and 3b, respectively, and the hinges 2 and 3 are fixed to the vehicle body.

Regarding the fixed hinge 2 on the vehicle body side, a part of the notched edge of the sheet metal is exposed at the part where one end of the movable hinge 3 on the back door side is fitted and connected due to processing, but when viewed from the hinge member 1 as a whole, a small portion is exposed. However, if surface treatment such as plating is applied, the appearance will not be impaired.

The rotating parts of the hinges 2 and 3 are constructed by fitting the head 31 of the hinge 3 into a U-shaped opening 21 of the hinge 2 and rotatably connecting both hinges with a shaft 4.

The opening 21 of the hinge 2 is provided with upright side walls 22.22 inclined inwardly to the extent that it allows the insertion and pivoting of the head 31 of the hinge 3, while the depending side walls 32.22 of the head 31 of the hinge 3 are provided. 32 also inclines outward in a divergent manner corresponding to the inclination of the rising side wall 22.22 at the opening 21 of the hinge 2, and connects the rising side wall 22.22 of the hinge 2 and the depending side wall 32.32 of the hinge 3 with a T-shaped washer. 41. The hinges 2, 41 are made to face each other in a sliding state through
3 is tightly fitted in the rotating part in such a manner that it does not interfere with the pivot rotation, so that the rotation can be achieved without play or loosening.

As explained above, this invention involves bending a pair of hinge members connected to each other by a shaft into an appropriate shape using a sheet metal, forming the entire exposed surface into a smooth curved surface, and forming the entire exposed surface into a smooth curved surface. This is an extremely inexpensive vehicle hinge component that is comparable in strength and design to conventional structures, and is characterized by being bent inward so that it is hidden in a shadowed area that serves as the mounting surface. This is something that can be provided.
