Preferably, the hinge nut plate is a structural member cut from a section steel.

The utility model also provides a connecting structure of the vehicle door and the vehicle body side wall, which comprises a vehicle door metal plate and the vehicle body side wall, wherein the vehicle door metal plate is rotatably connected to the vehicle body side wall through a hinge and a hinge nut plate; the hinge comprises a female hinge, a pin shaft and a male hinge, the hinge nut plate is connected to the vehicle door metal plate, the female hinge is connected with the vehicle body side wall, the male hinge is connected with the hinge nut plate, and the female hinge is rotatably connected with the male hinge through the pin shaft to realize the rotatable connection of the vehicle door and the vehicle body side wall; the female hinge and the male hinge are structural members formed by cutting section steel.

Preferably, the first and second electrodes are formed of a metal,

the hinge nut plate is welded to the inner side of the vehicle door metal plate, the male hinge is connected to the outer side of the vehicle door metal plate, and the bolt sequentially penetrates through the male hinge, the vehicle door metal plate and the hinge nut plate to realize fixation between the hinge and the vehicle door.

Preferably, the first and second electrodes are formed of a metal,

the female hinge is connected with the side wall of the vehicle body through two bolts, so that the hinge and the side wall of the vehicle body are fixed.

Preferably, the first and second electrodes are formed of a metal,

the hinge nut plate is a structural member cut from section steel.

By adopting the technical scheme, the beneficial technical effects of the utility model are as follows: the hinge is formed by cutting profile steel, the rigidity of the female hinge and the male hinge is stronger, the pin shaft is larger than that of a punching hinge, the rotation flexibility is good, the hinge is wear-resistant, the male hinge is connected with the vehicle door only through one bolt, the contact area of the male hinge and the vehicle door is small, and the anti-rust treatment is facilitated; the rigidity of the hinge that round pin axle, negative hinge and positive hinge formed is stronger, and consequently, the hinge that the shaped steel cutting formed will be littleer with the overall structure of punching press hinge, and the shaped steel hinge is stronger to installation environment adaptability on every side, and two hinge spans of lower part can be bigger on the door, can bear heavier weight, have promoted the door and have fallen the volume down for the door is strong in rigidity in Z orientation, promotes the stability and the deformation of door.

Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in fig. 2, a hinge nut plate 5 made of profile steel is welded on the inner side of the door sheet metal 1, and the hinge nut plate 5 is provided with bolt fixing holes which are aligned with bolt through holes on the door sheet metal 1.

As shown in fig. 4, the hinge made of the section steel comprises a female hinge 2 and a male hinge 4, the female hinge 2 and the male hinge 4 are rotatably connected through a pin shaft 3, two bolt through holes are formed in the female hinge 2, and one bolt through hole is formed in the male hinge 4.

As shown in fig. 3, the bolt through hole of the male hinge 4 is aligned with the bolt through hole on the door sheet metal 1 and the bolt fixing hole on the hinge nut plate 5, the male hinge 4, the door sheet metal 1 and the hinge nut plate 5 are connected into a whole by the bolt in sequence, and the male hinge 4 is connected to the inner side of the door sheet metal 1, so that the hinge is fixedly connected with the door side.

Specifically, the door sheet metal 1 is generally made thinner for weight reduction, and the rigidity of the hinge mounting point can be improved by the action of the hinge nut plate 5, and support is provided for deformation of the door sheet metal 1.

As shown in fig. 1, two bolt through holes on the female hinge 2 are aligned with two bolt fixing holes on the side wall of the vehicle body, the female hinge 2 is fixedly connected to the side wall of the vehicle body through two bolts, the connection between the hinge and the side wall of the vehicle body is realized, and finally, the rotatable connection between the vehicle door and the side wall of the vehicle body is realized.

The female hinge 2 and the male hinge 4 are made of profile steel, so that the rigidity is high, the rotation flexibility of the pin shaft is good, and the pin shaft is more wear-resistant. The male hinge 4 can be connected with the vehicle door metal plate 1 and the hinge nut plate 5 through only one bolt, and the contact area of the male hinge 4 and the vehicle door metal plate 1 is smaller, so that the anti-rust treatment is facilitated. Because the rigidity of negative hinge 2 and positive hinge 4 has been strong, the holistic structural dimension of hinge compares littleer with the punching press hinge, and consequently the hinge requires lowerly to the installation environment around, and adaptability is stronger, and the span of installing two hinges of lower part can be bigger on door panel beating 1, can bear heavier weight, has promoted the door and has fallen the volume down for the door is strong in the rigidity of Z to, promotes the stability and the deformation of door.
