The hinge mounting seat 10 further includes a mounting hole 11 of the mounting seat. The hinge mounting seat 10 may be mounted on the vehicle body frame of a vehicle.

[0016] The hinge arm 20 includes a working portion 20A of the hinge arm and a connection portion 20B of the hinge arm. The working portion 20A of the hinge arm includes a height adjustment axle block mounting portion 26 of the hinge arm and an opening state adjustment axle block mounting portion 27 of the hinge arm. The connection portion 20B of the hinge arm is provided with a door mounting hole 21 of the hinge arm, and the connection portion 20B of the hinge arm is used to connect with a door.

[0017] The axle-pin structure unit 30 includes a hinge height adjustment axle block 35 and a hinge opening state adjustment axle block 36. Further, with reference to FIG. 3, in the embodiment of the present invention, the hinge height adjustment axle block 35 is provided with a connection hole 351 of the hinge height adjustment axle block and a connection shaft 352 of the hinge height adjustment axle block. In some embodiments, the forms of the connection shaft and the connection hole are interchangeable, as long as an axial rotation is achieved. The connection hole 351 of the hinge height adjustment axle block is arranged on the first axle housing 13 of the mounting seat, and the hinge height adjustment axle block 35 cooperates with the first axle housing 13 of the mounting seat to form a first rotation axis 31. The connection shaft 352 of the hinge height adjustment axle block is connected to the height adjustment axle block mounting portion 26 of the hinge arm, which cooperate to form a second rotation axis 32. Further, with reference to FIG. 4, the hinge opening state adjustment axle block 36 includes a first connection hole 361 of the hinge opening state adjustment axle block and a second connection hole 362 of the hinge opening state adjustment axle block. In some embodiments, the connection holes of the hinge opening state adjustment axle block 36 may also be connection shafts. The first connection hole 361 of the hinge opening state adjustment axle block is connected to and cooperates with the second axle housing 14 of the mounting seat to form a third rotation axis 33. The second connection hole 362 of the hinge opening state adjustment axle block is connected to and cooperates with the opening state adjustment axle block mounting portion 27 of the hinge arm to form a fourth rotation axis 34. Furthermore, the hinge opening state adjustment axle block 36 is further provided with a stop protrusion 363 of the hinge opening state adjustment axle block. When the hinge arm 20 is opened to the maximum opening, the stop protrusion 363 of the hinge opening state adjustment axle block abuts against the hinge mounting seat 10. Furthermore, relative movement of the hinge arm 20 and the hinge mounting seat 10 can be achieve through the axle-pin structure unit 30. When the vehicle door hinge 100 is opened, the hinge height adjustment axle block 35 rotates around the first rotation axis 31, the hinge arm 20 rotates around the second rotation axis 32, and the first connection hole 361 and the second connection hole 362 of the hinge opening state adjustment axle block 36 respectively rotate around the third rotation axis 33 and the fourth rotation axis 34. The vehicle door hinge simplifies the movement of the door to a coordinated rotational movement rotating around the four rotation axes through the axle-pin structure unit 30.

[0018] In some embodiments, the first rotation axis 31, the second rotation axis 32, the third rotation axis 33, and the fourth rotation axis 34 intersect at a point, and the intersection point is on the hinge height adjustment axle block 35.

[0019] In some embodiments, the hinge arm 20 includes an upper hinge slider ball 23 and a lower hinge slider ball 28.

Referring to FIGS. 5-6, the upper hinge slider block 40 is provided with an upper hinge slider block slideway 401, and the lower hinge slider block 41 is provided with a lower hinge slider block slideway 411. The upper hinge slider block 40 and the lower hinge slider block 41 are fixed to the hinge mounting seat 100, and a space for the hinge arm 20 to pass is formed between the upper hinge slider block 40 and the lower hinge slider block 41. The hinge arm 20 abuts against the upper hinge slider block slideway 401 and the lower hinge slider block slideway 411 respectively through the upper hinge slider ball 23 and the lower hinge slider ball 28, and the hinge slider balls are slidable along the hinge slider slideways. The hinge sliders can provide stable support for the hinge arm, which further increases the stability of the vehicle door hinge 100 when it is opened.

[0020] In some embodiments, the vehicle door hinge 100 further includes a limiting unit, which includes an upper hinge limiting block 51, a lower hinge limiting block 52, and a mid-hinge limiting block 53. The upper hinge limiting block 51 is arranged on the hinge mounting seat 10, the lower hinge limiting block 52 is arranged on the vehicle body frame, and the mid-hinge limiting block 53 is arranged on the upper hinge slider block 40. The upper hinge limiting block 51 and the lower hinge limiting block 52 limits displacement of the connection portion 20B of the hinge arm, and the mid-hinge limiting block 53 limits displacement of the working portion 20A of the hinge arm. The limiting unit can ensure the stability of the door in a closed state.

[0021] In some embodiments, the vehicle door hinge 100 further includes a gas spring 60 and an electric strut 70. An end of the gas spring 60 is connected to a vehicle body frame, and the other end is connected to a gas spring mounting ball 24 of the hinge arm. An end of the electric strut 70 is connected to a vehicle body frame 200, and the other end is connected to an electric strut mounting ball 22. The gas spring mounting ball 24 and the electric strut mounting ball 22 are arranged on the hinge arm 20. The electric strut 70 is used to provide electric power for opening the door without manual operations, and the vehicle door hinge 100 can hover at any opening position. The gas spring 60 can provide pushing force for opening the hinge, and carry the door weight, and assist the electric strut 70 to open and close the door, thereby increasing the stability of the door during opening of the door.

[0022] Further, a mounting bracket 61 of the gas spring is provided between the gas spring 60 and the vehicle body frame 200; and a mounting bracket 71 of the electric strut is provided between the electric strut 70 and the vehicle body frame 200, to increase the mechanical performance of the vehicle body frame 200.
