[0035] like Figures 1 to 5 As shown, one embodiment of this utility model provides a car door hinge, including a pin 100, a mounting nut 200, an upper hinge arm 300 connected to the car body, and a lower hinge arm 400 connected to the car door; the pin 100 includes a first shaft segment 110, a second shaft segment 120 rotatably connected to the upper hinge arm 300, and a limiting flange 130 disposed between the second shaft segment 120 and the first shaft segment 110; the first shaft segment 110 includes a first connecting shaft portion 111 connected to the limiting flange 130, and a threaded segment 112 connected to one end of the first connecting shaft portion 111 away from the limiting flange 130; the lower hinge arm 400 is rotatably mounted on the first connecting shaft portion 111; the mounting nut 200 is threadedly mounted on the threaded segment 112.

[0036] In this embodiment, the door hinges are used in vehicles, particularly vehicles with gull-wing doors. The number and position of the door hinges can be set according to actual conditions. For example, two (or more) door hinges can be spaced apart between the top of the door and the vehicle body to ensure the stability of the door opening. Understandably, the door can be connected to the lower hinge arm 400 by a first bolt, and the vehicle body can be connected to the upper hinge arm 300 by a second bolt, thereby allowing the door to be mounted on the vehicle body via the door hinges.

[0037] In this embodiment, when the door needs to be installed on the vehicle body, the second shaft section 120 of the pin shaft 100 can be first rotationally connected with the upper hinge arm 300, and the upper hinge arm 300 is fixedly installed on the vehicle body through the second bolt; after the lower hinge arm 400 is fixedly installed on the door through the first bolt, the lower hinge arm 400 is rotationally connected on the first connecting shaft part 111 of the pin shaft 100, and the lower hinge arm 400 is limited between the mounting nut 200 and the limiting flange 130 through the mounting nut 200, so that the rotational connection between the door and the vehicle body is realized through the door hinge. After the door and the vehicle body are rotationally connected, the installation position of the mounting nut 200 on the threaded section 112 can be adjusted to adjust the positional relationship between the door and the vehicle body in the length direction of the vehicle, thereby improving the aesthetics of the gap between the door and the vehicle body.

[0038] It can be understood that the shape of the upper hinge arm 300 can be set according to actual conditions, thereby facilitating installation on the vehicle body. The shape of the lower hinge arm 400 can be set according to actual conditions, thereby facilitating installation on the door. The connection mode of the second shaft section 120 and the upper hinge arm 300 can be set according to actual conditions, as long as the second shaft section 120 and the upper hinge arm 300 can be rotationally connected. The shape of the limiting flange 130 can be set according to actual conditions, as long as the upper hinge arm 300 installed on the second shaft section 120 can be limited from moving towards the first shaft section 110, and the lower hinge arm 400 installed on the first shaft section 110 can be limited from moving towards the second shaft section 120. The mounting nut 200 includes but is not limited to one or more of self-locking nuts, lock nuts or other ordinary nuts, as long as the lower hinge arm 400 can be limited between the mounting nut 200 and the limiting flange 130.

[0039] It can be understood that the mounting nut 200 can only limit the lower hinge arm 400 between the mounting nut 200 and the limiting flange 130, at this time, the connection relationship between the lower hinge arm 400 and the first connecting shaft part 111 is rotational connection; the mounting nut 200 can also abut the lower hinge arm 400 on the limiting flange 130, at this time, the lower hinge arm 400 is fixed on the first connecting shaft part 111 by the mounting nut 200, that is, the lower hinge arm 400 and the first connecting shaft part 111 cannot produce relative rotation due to being fixed by the mounting nut 200.

[0040] The first shaft section 110, the second shaft section 120 and the limiting flange 130 can be coaxial or different in accordance with actual conditions, as long as the upper hinge arm 300 and the lower hinge arm 400 can be rotationally connected, and the vehicle door and the vehicle body do not interfere with each other during rotation. The connection mode between the first shaft section 110, the second shaft section 120 and the limiting flange 130 includes but is not limited to one or more of integral molding, welding or clamping, as long as the first shaft section 110, the second shaft section 120 and the limiting flange 130 can be stably connected. In an embodiment, the pin shaft 100 is an integral molding structure, thereby improving the structural stability between the first shaft section 110, the second shaft section 120 and the limiting flange 130.

The number of the mounting adjustment hole 420 can be set according to actual conditions, as long as the lower hinge arm 400 can be stably connected with the vehicle door. The position of the mounting adjustment hole 420 can be set according to actual conditions, so as to facilitate the mounting on the vehicle door.

[0047] In an embodiment, an adjustment gap is provided between the inner side wall of the mounting adjustment hole 420 and the outer side wall of the first bolt located in the mounting adjustment hole 420. It can be understood that the shape of the mounting adjustment hole 420 can be set according to actual conditions, as long as the first bolt can pass through, and the adjustment gap is provided between the inner side wall of the mounting adjustment hole 420 and the first bolt, so that the position of the lower hinge arm 400 can be adjusted in the radial direction of the first bolt; in this way, after the vehicle door and the vehicle body are rotatably connected, the position relationship between the vehicle door and the vehicle body in the height and width directions of the vehicle can be further adjusted by adjusting the mounting position of the lower hinge arm 400 in the radial direction of the first bolt, and the gap size between the vehicle door and the vehicle body is adjusted, and the appearance of the vehicle is improved.
