[0002] The car door is an important part of the car. Usually, the car door and the car body are hinged together with a hinge mechanism. The hinge is usually installed by directly welding it to the door panel. However, this direct connection method has low strength and is only suitable for the doors of light vehicles. In order to improve the overall protection capability of special-purpose vehicles such as bulletproof special vehicles, the doors usually need to be designed with weight and thickness. In this case, the pressure-bearing capacity of the door connection hinge is much greater than that of conventional doors. With simple welding and fixing methods, the connection hinge is prone to deformation after a long period of door opening and closing, resulting in poor opening and closing of the door, and even the possibility of the door falling off. Utility Model Content

[0003] To this end, the utility model provides a door hinge reinforcement assembly, which increases the strength of the position by arranging a hinge reinforcement sheet metal at the hinge installation position of the door connecting plate, and installs the door hinge by connecting the door hinge with a hinge fixing member. In this way, a part of the pressure-bearing part of the door hinge will be transferred to the hinge fixing member, so as to achieve the purpose of protecting the door hinge.

[0007] The first door hinge is arranged on a side of the door connecting plate away from the hinge reinforcing sheet metal component, and the first door hinge is fixedly connected to the first hinge fixing component via a locking connection mechanism.

[0008] Furthermore, it also includes a second hinge fixing part and a second door hinge, the second hinge fixing part is fixedly connected to the hinge reinforcement sheet metal part, and the second hinge fixing part and the first hinge fixing part are arranged on the same side of the hinge reinforcement sheet metal part, the second door hinge is arranged on the side of the door connecting plate away from the hinge reinforcement sheet metal part, and the second door hinge and the second hinge fixing part are fixedly connected by a locking connection mechanism.

[0009] Furthermore, a second positioning groove is provided on a side of the second hinge fixing member facing the hinge reinforcement sheet metal member, and a second positioning boss matched with the second positioning groove is provided on a side of the hinge reinforcement sheet metal member facing the second hinge fixing member.

[0010] Furthermore, the locking connection mechanism is a bolt fastening connection mechanism.

[0011] Furthermore, the first door hinge and the first hinge fixing member are fixedly connected by three groups of bolt fastening connection mechanisms, and the three groups of bolt fastening connection mechanisms are arranged in a non-linear manner. The second door hinge and the second hinge fixing member are fixedly connected by three groups of bolt fastening connection mechanisms, and the three groups of bolt fastening connection mechanisms are arranged in a non-linear manner.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the scheme of the utility model, a hinge reinforcement sheet metal is arranged at the hinge installation position of the door connecting plate to specifically improve the strength of the position and reduce the possibility of deformation of the door at the position.
