The first mounting shaft seat 11 can be integrated with the first mounting seat 1 by one-piece molding; the first mounting shaft seat 11 can also be fixed on the first mounting seat 1 by screwing, welding or gluing.

[0055] In one embodiment, the first mounting shaft seat 11 includes a first limiting seat and a second limiting seat, the first limiting seat and the second limiting seat being spaced apart, wherein one end of the first connecting rod 3 has a rotation axis, wherein the rotation axis is disposed between the first limiting seat and the second limiting seat, and the rotation axis is rotatably connected to the first limiting seat and the second limiting seat, thereby enabling the first connecting rod 3 to rotate about the rotation axis. In another embodiment, the first limiting seat, the second limiting seat, and one end of the first connecting rod 3 are each provided with an axial hole, wherein the rotation axis passes through the axial hole, thereby enabling the first connecting rod 3 to rotate about the rotation axis.

[0056] Among them, the second mounting shaft seat 12 is fixed on the first mounting seat 1. The second mounting shaft seat 12 can be integrally formed with the first mounting seat 1; the second mounting shaft seat 12 can also be fixed on the first mounting seat 1 by welding or gluing.

[0057] In one embodiment, the second mounting shaft seat 12 may be a pin, wherein one end of the second connecting rod 4 is provided with an axial hole, wherein the axial hole of the second connecting rod 4 is rotatably connected to the pin, thereby enabling the second connecting rod 4 to rotate about the pin. In other embodiments, the second mounting shaft seat 12 and the second connecting rod 4 may be rotatably connected via a shaft and a bearing.

[0058] As shown in Figure 1, one end of the third link 5 is hinged to the other end of the second link 4. The second link 4 and the third link 5 can be connected by a pin, or one end of the second link 4 and the third link 5 is provided with a rotating shaft and the other end is provided with an axial hole, and the second link 4 and the third link 5 are rotatably connected by the rotating shaft and the axial hole, so that the third link 5 and the second link 4 can rotate relative to each other around the rotating shaft.

[0059] As shown in Figure 1, the second mounting base 2 is used to be mounted and fixed on the vehicle door. The second mounting base 2 and the vehicle door can be mounted and fixed by welding, screwing, gluing, etc., and can be screwed to facilitate assembly and replacement.

[0060] The second mounting seat 2 has a first mounting point and a second mounting point, wherein the first mounting point is hinged to the first connecting rod 3 , and the second mounting point is hinged to the third connecting rod 5 .

[0061] The first mounting point has two spaced-apart mounting bases, wherein the other end of the first connecting rod 3 is provided with a rotating shaft, which is rotatably connected to the mounting base via the rotating shaft, thereby enabling the first connecting rod 3 and the second mounting base 2 to rotate relative to each other about the rotating shaft. In another embodiment, the other end of the first connecting rod 3 and the two mounting bases are provided with an axial hole, and the first connecting rod 3 and the second mounting base 2 are rotatably connected to the axial hole via the rotating shaft, thereby enabling the first connecting rod 3 and the second mounting base 2 to rotate relative to each other about the rotating shaft.

[0062] The second mounting point is hinged to the other end of the third connecting rod 5 .

[0063] In the prior art, the door hinge 100 of a scissor door usually adopts a spatial spherical four-bar linkage, which means that the rotation axes of the three rotating shafts of the spatial spherical four-bar linkage need to intersect at one point so that the door can be opened smoothly. When installing the door hinge 100, high assembly precision is required. If an error occurs, it will cause jamming during the opening and closing of the door.

[0064] As shown in Figure 1, the vehicle door hinge 100 disclosed in the present invention adopts a spatial five-link mechanism, so during installation, the first link 3 is hinged to the first mounting shaft seat 11, the second link 4 is hinged to the second mounting shaft seat 12 and the second mounting seat 2 respectively, and the third link 5 is hinged to the second link 4 without affecting each other, and when the third link 5 is hinged to the second mounting seat 2, the second link 4 and the third link 5 can rotate relative to each other, and a relative free space is provided for the installation between the third link 5 and the second mounting seat 2. Therefore, when the vehicle door hinge 100 provided in the present invention is assembled with the vehicle door and the vehicle body, the assembly precision required is low and it is easy to install, thereby improving production efficiency.

[0065] When the door hinge 100 disclosed herein is opened, that is, when the door is opened, the first connecting rod 3 rotates around the first rotation axis L1, the second mounting seat 2 rotates around the second rotation axis L2, and the second connecting rod 4 rotates around the third rotation axis L3. The second connecting rod 4 and the second mounting seat 2 are hinged by a ball head pair 6, and the other end of the second connecting rod 4 rotates around the rotation axis of the ball head pair. Therefore, when the door hinge 100 is opened, the movement of the door is simplified to a coordinated movement around three rotation axes and a ball head pair 6, which can make the movement trajectory of the door consistent, thereby making the movement of the door have higher stability.

[0066] In some embodiments of the present disclosure, the first link 3 is hinged to the first mounting shaft seat 11 to form a first rotation axis L1, the first link 3 is hinged to the second mounting shaft seat 2 to form a second rotation axis L2, the second link 4 is hinged to the second mounting shaft seat 12 to form a third rotation axis L3, and the third link 5 is hinged to the second link 4 to form a fourth rotation axis L4; the projections of the first rotation axis L1, the second rotation axis L2, the third rotation axis L3, and the fourth rotation axis L4 on the XY plane have multiple intersection points.

[0067] The intersection points mentioned in this disclosure may be intersections in the same plane or intersections in space.

[0068] As shown in FIG. 4 and FIG. 5 , the first rotation axis L1 , the second rotation axis L2 , the third rotation axis L3 , and the fourth rotation axis L4 have a plurality of intersection points.

[0069] In the first embodiment, the first rotation axis L1 and the second rotation axis L2 have an intersection, and the first rotation axis L1 and the second rotation axis L2 have an intersection with the third rotation axis L3 and the fourth rotation axis L4 respectively, which means that the door hinge 100 has a higher degree of assembly freedom during assembly, the required assembly precision is lower, and it is easy to install, thereby improving production efficiency.

[0070] In the second embodiment, the first rotation axis L1 , the second rotation axis L2 , and the third rotation axis L3 have an intersection point, and the first rotation axis L1 , the second rotation axis L2 , and the fourth rotation axis L4 have an intersection point.

[0071] In some embodiments of the present disclosure, the first connecting rod 3 is connected to the first mounting shaft seat 11 through a rotating pair, the first connecting rod 3 is connected to the second mounting seat 2 through a rotating pair, the second connecting rod 4 is connected to the second mounting shaft seat 12 through a rotating pair, the second connecting rod 4 is connected to the third connecting rod 5 through a rotating pair, and the third connecting rod 5 is connected to the second mounting seat 2 through a ball head pair 6.

[0072] The first connecting rod 3 and the first mounting shaft seat 11, the first connecting rod 3 and the second mounting shaft seat 12, the second connecting rod 4 and the second mounting seat 2, and the second connecting rod 4 and the third connecting rod 5 are all connected through a revolute pair, and the third connecting rod 5 and the second mounting seat 2 are connected through a ball joint.

[0073] The ball head pair 6 includes a ball head 61 and a ball cap 62 . The ball head 61 is arranged at the other end of the third connecting rod 5 , and the ball cap 62 is arranged on the second mounting seat 2 . The ball head 61 and the ball cap 62 are hinged.

[0074] As shown in FIG. 1 and FIG. 3 , a ball head 61 is provided at the other end of the third connecting rod 5 , wherein the ball head 61 can be fixed to the third connecting rod 5 by riveting, screwing or welding.

[0075] A spherical cap 62 is provided at the second mounting point of the second mounting seat 2 , wherein the spherical cap 62 can be fixed to the second mounting seat 2 by riveting, screwing or welding.

[0076] When the ball head 61 and the ball cap 62 are assembled, the ball head 61 is inserted into the ball cap 62 , and the ball head 61 is allowed to rotate relatively inside the ball cap 62 .

[0077] In some embodiments of the present disclosure, a first rotation axis L1 formed by the first connecting rod 3 and the first mounting shaft seat 11 intersects with a second rotation axis L1 formed by the first connecting rod 3 and the second mounting seat 1 .

[0078] The first rotation axis L1 intersects with the second rotation axis L2, and the first rotation axis L1 intersects with the third rotation axis L3 and the fourth rotation axis L4 respectively, and the second rotation axis L2 intersects with the third rotation axis L3 and the fourth rotation axis L4 respectively, which means that there are multiple intersection points between the rotation axes, which means that the door hinge 100 has a higher degree of assembly freedom during assembly, the required assembly precision is lower, and it is easy to install, thereby improving production efficiency.

[0079] In some embodiments of the present disclosure, the third rotation axis L3 formed by the second connecting rod 4 and the second mounting shaft seat 12 is parallel to the fourth rotation axis L4 formed by the third connecting rod 5 and the second connecting rod 4 .

[0080] The third rotation axis L3 is parallel to the fourth rotation axis L4, which ensures that the first rotation axis L1, the second rotation axis L2, the third rotation axis L3 and the fourth rotation axis L4 will not intersect at one point, so that the door hinge 100 has a higher degree of assembly freedom during assembly, the required assembly precision is lower, and it is easy to install, thereby improving production efficiency.

[0081] In some embodiments of the present disclosure, the third rotation axis L3 and the fourth rotation axis L4 are perpendicular to the XZ plane.

[0082] As shown in Figure 5, the third rotation axis L3 and the fourth rotation axis L4 are both perpendicular to the XZ plane, and the third rotation axis L3 and the fourth rotation axis L4 are parallel to each other. The third rotation axis L3 and the fourth rotation axis L4 are perpendicular to the XZ plane, which can reduce the assembly accuracy of the door hinge 100, and when the door is opened and closed, the movement between the second connecting rod 4 and the second mounting shaft seat 12, and between the third connecting rod 5 and the second connecting rod 4 is smoother, avoiding the phenomenon of jamming.

[0083] As shown in FIG1 and FIG4 , in some embodiments of the present disclosure, when the door is closed, the plane enclosed by the first rotation axis L1 and the second rotation axis L2 is a first plane, and the angle between the first plane and the XZ plane is less than π / 18.

[0084] The two lines can form a plane, and the first rotation axis L1 and the second rotation axis L2 enclose a first plane.

[0085] The XZ plane is a plane formed by the X direction and the Z direction indicated in the figure.

[0086] The angle between the first plane and the XZ plane is less than π / 18, where π refers to 180°; at this angle, the second mounting seat 2 can move a larger angle in the Z direction.

[0087] As shown in Figure 9, in some embodiments of the present disclosure, the first mounting shaft seat 11 has a first limiting portion 111, and the first limiting portion 111 has a first limiting plane 1111; the first connecting rod 3 has a second limiting portion 31, and the second limiting portion 31 has a second limiting plane 311, and the angle between the second limiting plane 311 and the first limiting plane 1111 is in the range of π / 2-2π / 3.

[0088] The first mounting shaft seat 11 has a first limiting portion 111 , wherein the first limiting plane 1111 is a surface on the first limiting portion 111 ; the first mounting seat plane refers to the plane where the first mounting shaft seat 11 is fixed to the first mounting seat 1 .

[0089] The first connecting rod 3 has a second limiting portion 31 , wherein the second limiting plane 311 is a surface on the second limiting portion 31 . When the first connecting rod 3 rotates to a preset angle, the second limiting plane 311 can cooperate with the first limiting plane 1111 for limiting.

[0090] During the door opening process, the first link 3 rotates in the Y direction, and the second limiting portion 311 can cooperate with the first limiting portion 1111 to limit the position, thereby limiting the maximum rotation angle of the first link 3 by the first limiting portion 1111. When the door is closed, the angle between the first limiting plane 1111 and the first mounting seat plane is less than π / 36, and the angle between the second limiting plane 311 and the first limiting plane 1111 is between π / 2 and 2π / 3. When the first link 3 rotates about the first rotation axis L1 to a range between π / 2 and 2π / 3, the door hinge 100 reaches a hard limit point. An electric spring, pneumatic spring, or balancing spring can be used to softly stop the first link 3 before it rotates about the first rotation axis L1 by (π / 2-π / 36)-(2π / 3-π / 36), thereby preventing the first link 3 or the second mounting seat 2 from colliding with other components.

[0091] In some embodiments of the present disclosure, the first rotation axis L1 and the second rotation axis L2 respectively form an angle with the Y-axis.

[0092] The first rotation axis L1 forms a first angle with the Y-axis, and the second rotation axis L2 forms a second angle with the Y-axis. The first and second angles determine the motion trajectory of the door hinge 100, thereby allowing the door to open and close along the motion trajectory. The first and second angles can be selected based on actual needs and are not specifically limited in this disclosure.

[0093] In some embodiments of the present disclosure, when the vehicle door is opened, the second mounting base 2 moves, the first connecting rod 3 can rotate unidirectionally around the first rotation axis L1, and the second connecting rod 4 can rotate reciprocatingly around the third rotation axis L3.

[0094] In the present disclosure, when the vehicle door is opened, that is, when the vehicle door is opened from closed to open.

[0095] As shown in Figures 6 and 8, when the car door is opened, the second mounting seat 2 undergoes spatial movement. When the opening movement begins, the first connecting rod 3 rotates around the first rotation axis L1. At this time, the second mounting seat 2 and the third connecting rod 5 rotate spherically under the action of the ball head pair 6, which in turn drives the planar movement of the third connecting rod 5 and the second connecting rod 4 to rotate around the second rotation axis L2. During the movement, the first connecting rod 3 rotates unidirectionally around the first rotation axis L1, and the second connecting rod 4 swings back and forth around the third rotation axis L3. Since this mechanism is a motion mechanism with four rotation pairs and one spherical pair, the first rotation axis L1, the second rotation axis L2, the third rotation axis L3 and the fourth rotation axis L4 serve as rotation pairs, and the ball head pair 6 serves as a spherical pair, thus forming a spatial five-bar mechanism. Through the coordinated movement of four rotation pairs and one spherical pair, the movement trajectory of the car door can be made consistent, thereby making the movement of the car door have higher stability.

[0096] As shown in Figure 7, the second mounting seat 2 moves along the Y direction and the Z direction during the movement process, and its motion trajectory is arc-shaped, that is, the motion trajectory of the cosine state equation, and finally forms an open second mounting seat 2, realizing a combined motion action of first opening sideways and then rotating upward, wherein the side opening angle is less than π / 4 and the upward rotation angle is less than 5π / 18.

[0097] In some embodiments of the present disclosure, a ball stud mounting seat 21 is provided on the second mounting seat 2, and the ball stud mounting seat 21 is used to connect a driving component and / or a limiting component.

[0098] As shown in Figures 1 and 8, a ball stud mounting seat 21 is provided on the second mounting seat 2 for mounting a driving component and / or a limiting component. It is further explained that it is used to connect an electric spring, a pneumatic spring or a balancing spring.

[0099] In some embodiments of the present disclosure, both sides of the mounting surface of the ball stud mounting seat 21 have reinforcing ribs 211, which can improve the local stiffness of the second mounting seat 2 and the stability of the second mounting seat 2 in controlling the vehicle door.

[0100] In some embodiments of the present disclosure, a wire harness mounting hole 22 is provided on the second mounting seat 2 to provide a routing channel for the wire harness and to fix the wire harness.

[0101] According to a second aspect of an embodiment of the present disclosure, a vehicle is provided, comprising the above-mentioned door hinge 100 , a door and a vehicle body, wherein the second mounting seat 2 is mounted on the door, and the first mounting seat 1 is mounted on the vehicle body.

[0102] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art will understand that the above examples are for illustration only and are not intended to limit the scope of the present disclosure. Those skilled in the art will understand that the above embodiments may be modified without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
