[0026] Reference Figures 1 to 3 , a new type of door hinge, comprising:

[0027] The hinge mounting seat 10 is arranged on the vehicle body 21, and a first rotating seat 11 and a second rotating seat 12 are arranged on the hinge mounting seat 10;

[0028] The connecting arm 30 includes a first connecting portion 31, a second connecting portion 32 and a third connecting portion 33 connected in sequence, the other end of the first connecting portion 31 can be rotatably connected to the output end of the first driving device 41, and the other end of the third connecting portion 33 can be rotatably connected to the second driving device 42 and can be connected to the vehicle door 22;

[0029] The first rotating portion 50 has two ends rotatably connected to the first rotating seat 11 and the second connecting portion 32 to form a first rotating axis 81 and a second rotating axis 82 for adjusting the height of the door 22;

[0030] The second rotating part 60 has two ends rotatably connected to the second rotating seat 12 and the second rotating part 32, respectively, to form a third rotating axis 83 and a fourth rotating axis 84, respectively, for adjusting the opening of the door 22;

[0031] The third rotating part 70 is rotatably connected to the second rotating part 60 at one end and is connected to the third connecting part 33 at the other end to form a fifth rotating axis 85. The connection point 91 between the third rotating part 70 and the third connecting part 33 is higher than the connection point 92 between the second connecting part 32 and the third connecting part 33. The first rotating axis 81, the second rotating axis 82, the third rotating axis 83 and the fourth rotating axis 84 intersect at one point.

[0032] In the present invention, when the door is opened, the first driving device 41 drives the first connecting portion 31 on the connecting arm 30 to move downward, and the second driving device 42 drives the third connecting portion 33 on the connecting arm 30 to move upward, and the various components move in coordination around the first rotation axis 81, the second rotation axis 82, the third rotation axis 83 and the fourth rotation axis 84, so as to realize the upward and outward opening of the door 22; and by providing the third rotating portion 70, one end of which is rotationally connected to the second rotating portion 60, and the other end of which is connected to the third connecting portion 33, so as to form a fifth rotation axis Line 85, the connection point 91 between the third rotating part 70 and the third connecting part 33 is higher than the connection point 92 between the second connecting part 32 and the third connecting part 33, so that the third rotating part 70 can provide better support for the third connecting part 33 when the vehicle door 22 is opened upward and outward. Especially under high temperature (60°C), components such as gas springs may have insufficient support for the vehicle door 22 due to thermal attenuation. The arrangement of the third rotating part 70 and the fifth rotating axis 85 can make the vehicle door 22 open more smoothly, bringing a better user experience.

[0033] The intersection of the first rotation axis 81 , the second rotation axis 82 , the third rotation axis 83 , and the fourth rotation axis 84 is located on the first rotation portion 50 .

[0034] The fifth rotation axis 85 is parallel to the fourth rotation axis 84 .

[0035] The first driving device 41 is configured as an electric strut; the second driving device 42 is configured as a gas spring; the electric strut is driven by electricity, so that the door can be opened and closed automatically without the need for the driver or passengers to open and close it manually, and can hover at any angle. It only requires setting the start and close time of the electric strut, and the gas spring can provide an upward thrust for the opening of the door and is used to bear the gravity of the door.

[0036] The output end of the first drive device 41 is connected to the first connection part 31 through the first ball and socket connection structure 93, and the output end of the second drive device 42 is connected to the third connection part 33 through the second ball and socket connection structure 94; the ball and socket connection structure is used to achieve the connection firmness and stability between the first drive device 41 and the vehicle body 21, the first drive device 41 and the first connection part 31, the second drive device 42 and the vehicle body 21, and the second drive device 42 and the third connection part 33.

[0037] The first connection part 31, the second connection part 32 and the third connection part 33 are integrally formed; this arrangement can improve production efficiency while reducing the number of parts of the hinge, thereby reducing the possibility of abnormal noise.

[0038] A vehicle comprises the door hinge.
