[0002] With the rapid development of the vehicle industry and the improvement of people's living standards, there are high requirements for all-round vehicle performance, and the convenience during vehicle use is particularly the key concern of customers. For vehicle models with a tailgate, such as off-road vehicles, minivans or trucks, when loading or unloading large-sized items, the tailgate is usually opened for convenience. The hinge, as an indispensable part of a vehicle, plays a role in connecting the door and the vehicle body. Especially the hinge between the tailgate and the vehicle body not only facilitates the opening and closing of the tailgate, but also can limit the rotation of the hinge so that the tailgate can maintain a certain opening angle for convenient loading and unloading of items. Currently, the limit hook for restricting the rotation of the hinge on the market is usually separately arranged from the hinge. When it is necessary to limit the rotation of the hinge, the limit hook is inserted into the hinge; when closing the tailgate, the limit hook is taken out of the hinge.

[0030] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a certain specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0031] As Figures 1 to 5 shown, the door hinge of the present application includes a door fixing page 1, a body fixing page 2, a middle connecting page 3, and a link 4. The door fixing page 1 is used to connect with the door 5, and the body fixing page 2 is used to connect with the body 6. One end of the middle connecting page 3 and one end of the link 4 are rotatably connected to the door fixing page 1, and the other end of the middle connecting page 3 and the other end of the link 4 are rotatably connected to the body fixing page 2.

[0032] The door fixing page 1 can rotate relative to the body fixing page 2 through the middle connecting page 3 and the link 4, so that the door 5 can rotate relative to the body 6 to open or close the cabin. When the door fixing page 1 rotates to a specific position, the middle connecting page 3 can be connected to the link 4, so that the middle connecting page 3 and the link 4 are relatively fixed, and then the door fixing page 1 can be fixed relative to the body fixing page 2, so that the door 5 is stably in the open state, which is convenient for people to load and unload items.

[0033] In one embodiment, the door fixing page 1 includes a first fixing portion 11, a second fixing portion 12, a first hinge portion 13, and a second hinge portion 14. The first fixing portion 11 is fixed to the door 5, and the second fixing portion 12 extends by bending from the end of the first fixing portion 11. The first hinge portion 13 is provided at one end of the second fixing portion 12 adjacent to the first fixing portion 11, and the first hinge portion 13 can be connected to the middle connecting page 3 through a pin shaft. The second hinge portion 14 is provided at the end of the second fixing portion 12 away from the first fixing portion 11, and the second hinge portion 14 can be connected to the connecting rod 4 through a pin shaft.

[0034] The door fixing page 1 rotates relative to the middle connecting page 3 with the first hinge portion 13 as the rotation axis point. The second hinge portion 14 moves in a circular motion around the first hinge portion 13, and the door fixing page 1 drives the connecting rod 4 to move while rotating. There are two second fixing portions 12, and they are spaced apart on the first fixing portion 11. The end of the connecting rod 4 is located between the two second fixing portions 12.

[0035] The second fixing portion 12 extends by bending from the end of the first fixing portion 11, and the door fixing page 1 is connected to the middle connecting page 3 and the connecting rod 4 through different hinge points, so that when the middle connecting page 3 is connected to the connecting rod 4, the door fixing page 1 can be relatively fixed to the body fixing page 2.

[0036] Further combining Figure 6 As shown, in one embodiment, the body fixing page 2 includes a third fixing portion 21, a fourth fixing portion 22, a third hinge portion 23, and a fourth hinge portion 24. The third fixing portion 21 is fixed to the body 6, and the fourth fixing portion 22 extends by bending from the end of the third fixing portion 21. The third hinge portion 23 is provided at one end of the fourth fixing portion 22 adjacent to the third fixing portion 21, and the third hinge portion 23 can be connected to the connecting rod 4 through a pin shaft. The fourth hinge portion 24 is provided at the end of the fourth fixing portion 22 away from the third fixing portion 21, and the fourth hinge portion 24 can be connected to the middle connecting page 3 through a pin shaft.

[0037] The middle connecting page 3 rotates relative to the body fixing page 2 with the fourth hinge portion 24 as the rotation axis point, and the connecting rod 4 rotates relative to the body fixing page 2 with the third hinge portion 23 as the rotation axis point. There are two fourth fixing portions 22, and they are spaced apart on the third fixing portion 21. The end of the connecting rod 4 is located between the two fourth fixing portions 22.

[0038] In one embodiment, the middle connecting page 3 includes a connecting page main body 31, a limiting member 32 and an abutting member 33 movably provided on the connecting page main body 31. The limiting member 32 can contact the connecting rod 4, so that the middle connecting page 3 is connected to the connecting rod 4, so that the middle connecting page 3 and the connecting rod 4 are relatively fixed, and further the door fixing page 1 is fixed relative to the body fixing page 2. The abutting member 33 is used to lock the limiting member 32.

[0039] With such a setting, when the car door hinge is used on a vehicle, it can fix the car door 5 to prevent the car door 5 from rotating, so as to facilitate people to load and unload items. At the same time, the abutting member 33 can lock the limiting member 32, further improving the stability of the limiting member 32 during limiting. Moreover, when the limiting member 32 contacts or disengages from the connecting rod 4, the abutting member 33 can lock the limiting member 32 to prevent the limiting member 32 from being lost and reducing the use cost.

[0040] Further in combination with Figure 7 As shown, in an embodiment, the connecting page body 31 includes a first connecting rod 311, a limiting hole 312, a locking hole 313, a second connecting rod 314 and a connecting plate 315. One end of the first connecting rod 311 is connected to the first hinged portion 13, and the other end is connected to the fourth hinged portion 24. The limiting hole 312 and the locking hole 313 are provided on the first connecting rod 311. The limiting member 32 is movably arranged in the limiting hole 312, and the abutting member 33 is movably arranged in the locking hole 313. And the limiting hole 312 and the locking hole 313 are communicated with each other so that the abutting member 33 can be locked to the limiting member 32.

[0041] To facilitate the movement of the abutting member 33 to lock to the limiting member 32, the center line of the limiting hole 312 is perpendicular to the center line of the locking hole 313. And the limiting hole 312 penetrates through the first connecting rod 311 and faces the connecting rod 4, and the locking hole 313 penetrates from the side surface of the first connecting rod 311 to the limiting hole 312.

[0042] To improve the strength of the middle connecting page 3, the connecting plate 315 is fixed between the second connecting rod 314 and the first connecting rod 311, and the car door fixing page 1 and the vehicle body fixing page 2 are connected between the second connecting rod 314 and the first connecting rod 311. Preferably, the second connecting rod 314 and the first connecting rod 311 are of equal length, and the length of the connecting plate 315 is less than the lengths of the second connecting rod 314 and the first connecting rod 311, so as to avoid interference between the connecting plate 315 and the second fixing portion 12 and the fourth fixing portion 22 when the middle connecting page 3 rotates relative to the vehicle body fixing page 2 and the car door fixing page 1 rotates relative to the middle connecting page 3. The end of the first connecting rod 311 connected to the vehicle body fixing page 2 and the end of the second connecting rod 314 connected to the vehicle body fixing page 2 are both bent from the connecting plate 315.

[0043] In an embodiment, the limiting member 32 has a pin structure, and the limiting member 32 includes an upper screwing portion 321 and a lower inserting portion 322. Part of the upper screwing portion 321 is located in the limiting hole 312 and can slide or rotate in the limiting hole 312. The diameter of the lower inserting portion 322 is smaller than that of the upper screwing portion 321, and the lower inserting portion 322 can penetrate through the connecting rod 4. With such a setting, when the lower inserting portion 322 penetrates into the connecting rod 4, the upper screwing portion 321 with a larger diameter can contact the connecting rod 4, thereby limiting the upper screwing portion 321 and preventing the limiting member 32 from sliding down and disengaging from the first connecting rod 311.

[0044] As Figure 8 shown, in another embodiment, the limiting member 32 and the abutting member 33 are provided on the second connecting rod 314. The limiting member 32 includes a limiting portion 323 connected between the upper screwing portion 321 and the lower inserting portion 322. The limiting portion 323 can be limited to the second connecting rod 314 to prevent the limiting member 32 from falling off. Specifically, the limiting portion 323 can move between the second connecting rod 314 and the connecting rod 4, and the limiting portion 323 can contact the second connecting rod 314 to prevent the limiting member 32 from falling off the second connecting rod 314.

[0045] As Figure 9 shown, in another embodiment, the limiting member 32 includes an upper screwing portion 321 and a clamping portion 324. The clamping portion 324 is connected to the upper screwing portion 321, the upper screwing portion 321 has a columnar structure, and the clamping portion 324 has a U-shaped structure. The upper screwing portion 321 can move in the limiting hole 312, and the clamping portion 324 can be clamped to the connecting rod 4 so that the door fixed page 1 is fixed relative to the vehicle body fixed page 2.

[0046] In one embodiment, the abutting member 33 is a screw structure, and the abutting member 333 can be rotated by a tool to lock or move away from the limiting member 32. To facilitate the rotation of the abutting member 33, the abutting member 33 includes a screw portion 331 and a locking handle 332 connected to the screw portion 331. The screw portion 331 is located in the locking hole 313, and the locking handle 332 is used to assist in rotating the abutting member 33, as Figure 9 shown.

[0047] Combining again with Figure 7 shown, in one embodiment, the connecting rod 4 is provided with a rod main body 41 and a positioning portion 42 provided on the rod main body 41. One end of the rod main body 41 is connected to the second hinge portion 14, and the other end is connected to the third hinge portion 23. The lower inserting portion 322 cooperates with the positioning portion 42, so that the middle connecting page 3 can be connected to the connecting rod 4. There are multiple positioning portions 42, and they are spaced apart on the rod main body 41. The multiple positioning portions 42 can cooperate with the limiting member 32 one by one, so that the door fixed page 1 is in different positions relative to the vehicle body fixed page 2, meeting the requirements of different opening angles of the door 5.

[0048] The door hinge of the present application passes the limiting member 32 through the connecting rod 4, which can improve the stability when the door fixed page 1 is fixed to the vehicle body fixed page 2. When the door hinge is in use, the door 5 can be fixed at a specific angle, so that the door 5 is stably in the open state to facilitate the loading and unloading of items from the vehicle. At the same time, the abutting member 33 can lock the limiting member 32, further improving the stability and accuracy of the limiting member 32 during limiting. And when the limiting member 32 contacts or disengages from the connecting rod 4, the abutting member 33 can lock the limiting member 32 to prevent the limiting member 32 from being lost. The overall structure of the door hinge of the present application is simple in design, light in weight and low in cost.

[0049] The present application further provides a vehicle, including a vehicle door 5, a vehicle body 6, and the vehicle door hinge as described above, and the vehicle door hinge is connected between the vehicle door 5 and the vehicle body 6.
