The above-mentioned solution solves the problem of the existing universal hinge structure of the vehicle door. During the door opening process, the rotating stop part 108 directly hits the rotation angle limit block, which will generate a certain impact force and cause the vehicle door to vibrate, which may cause the connection of the parts to loosen.

[0023] According to this specific embodiment, the vehicle body panel 101 cooperates with the hinge assembly to be connected to the vehicle door to realize the opening and closing of the vehicle door.

[0024] Among them, the first connecting portion 103 is fixedly connected to the vehicle body page 101 and is located on one side of the vehicle body page 101; the rotating member 104 is arranged on one side of the first connecting portion 103; the first rivet pin 105 is arranged on one side of the first connecting portion 103; the second connecting portion 106 is located on one side of the rotating member 104; the door page 107 is fixedly connected to the second connecting portion 106 and is located on one side of the second connecting portion 106; the door assembly hole 112 is located on one side of the door page 107; the stop portion 108 is fixedly connected to the second connecting portion 106 and is located on one side of the second connecting portion 106; the limit frame 109 is fixedly connected to the vehicle body page 101 and is located on one side of the vehicle body page 101; the buffer member 110 is arranged inside the limit frame 109; the buffer plate 111 is fixedly connected to the buffer member 110 and is located on one side of the buffer member 110, and the door page 107 is connected to the first connecting portion through the second connecting portion 106 The rotating part 104 on the connecting part 103 is assembled and then fixed by a riveting process. The first rivet pin 105 is assembled to the first connecting part 103 by a riveting process to limit the movement of the rotating shaft. Then the body page 101 is assembled to the body through the body assembly hole 102, and the door page 107 is assembled to the door through the door assembly hole 112. When the door is opened, the second connecting part 106 drives the door page 107 to rotate on the rotating part 104. When the second connecting part 106 rotates, the stop part 108 hits the buffer plate 111 provided on the limit frame 109 on the body page 101.
