[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference below Figure 1-Figure 10 A door hinge mechanism 100 for a vehicle 1000 according to an embodiment of a first aspect of the present invention will be described.

[0041] The door hinge mechanism 100 according to the embodiment of the present invention can be used in a vehicle 1000. Specifically, the vehicle 1000 may include a vehicle body 200, a door 300 and a door hinge mechanism 100, wherein the door 300 may be a scissor door, and the door hinge mechanism 100 may include: a first rotating arm 3, a second rotating arm 4 and a transition arm 5.

[0042] Among them, reference Figure 3 and Figure 7 One end of the first rotating arm 3 is suitable for being rotatably connected to the vehicle body 200 around a first rotating axis a, the vehicle door 300 is suitable for being rotatably connected to the other end of the first rotating arm 3 around a second rotating axis b, and one end of the second rotating arm 4 is suitable for being rotatably connected to the vehicle body 200 around a third rotating axis c; one end of the transition arm 5 is rotatably connected to the other end of the second rotating arm 4, the vehicle door 300 is suitable for being rotatably connected to the other end of the transition arm 5 around a fourth rotating axis d, and the first rotating axis a and the third rotating axis c are parallel to each other, the second rotating axis b and the fourth rotating axis d are parallel to each other, and the first rotating axis a and the second rotating axis b are not parallel.

[0043] For example, if the vehicle door 300 is a scissor door, the opening direction of the scissor door is usually outward and upward at the same time, that is, inclined upward. It is defined here that the first rotation axis a extends along the first direction, and the second rotation axis b extends along the second direction. The first direction and the second direction are different, that is, the first rotation axis a and the second rotation axis b are not parallel. In this way, the first rotating arm 3, the second rotating arm 4, the transition arm 5 and the vehicle door 300 as a whole rotate around the rotation axis of the first direction (including the above-mentioned first rotation axis a and the third rotation axis c), and the vehicle door 300 can rotate around the rotation axis of the second direction (including the above-mentioned second rotation axis b and the fourth rotation axis d). When the rotational motion of the vehicle door 300 around the first direction and the second direction is combined, the scissor door can be opened. Optionally, the extension direction of the first rotation axis a and the second rotation axis b can be reasonably selected according to the opening direction of the vehicle door 300.

[0044] Compared with the scheme in the related art in which the extension directions of the rotation axes at different joints of the hinge mechanism are different, which easily leads to the complexity of the overall structure and motion coordination form of the hinge mechanism, cumbersome assembly procedures, and large occupied space, this scheme can make the overall structure and motion coordination form of the door hinge mechanism 100 simpler because the first rotation axis a and the third rotation axis are parallel to each other, and the second rotation axis b and the fourth rotation axis d are parallel to each other, which is beneficial to reducing the space occupied by the door hinge mechanism 100 and facilitating assembly, manufacturing and later maintenance.

[0045] In addition, since the general opening direction of the scissor door is obliquely upward, during the opening process of the vehicle door 300, different parts of the vehicle door 300 in the up and down directions move different distances relative to the corresponding positions of the vehicle body 200 (with the vehicle door 300 in the closed state as a reference). In this embodiment, a transition arm 5 is provided between the second rotating arm 4 and the vehicle door 300. The transition arm 5 is rotatable relative to the second rotating arm 4, which can provide sufficient movement margin for the vehicle door 300, thereby allowing the vehicle door 300 to be smoothly opened or closed.

[0046] According to the door hinge mechanism 100 for the vehicle 1000 of the embodiment of the present invention, the first rotation axis a and the third rotation axis are parallel to each other, and the second rotation axis b and the fourth rotation axis d are parallel to each other, which can make the overall structure and motion coordination form of the door hinge mechanism 100 simpler, which is conducive to reducing the space occupied by the door hinge mechanism 100, and is convenient for assembly, manufacturing and later maintenance. Since the general opening direction of the door 300 is obliquely upward, during the opening process of the door 300, different parts of the door 300 in the up and down directions have different movement distances relative to the corresponding positions of the vehicle body 200 (with the door 300 in the closed state as a reference). By arranging a transition arm 5 between the second rotating arm 4 and the door 300, the transition arm 5 can rotate relative to the second rotating arm 4, which can provide sufficient movement margin for the position of the door 300 corresponding to the second rotating arm 4, so that the door 300 can be opened or closed smoothly.

[0047] According to some embodiments of the present invention, reference Figure 3 and Figure 7 , one of the first rotation axis a and the second rotation axis b extends in the vertical direction and the other extends in the horizontal direction.

[0048] For example, the first rotation axis a and the third rotation axis c can both extend in the vertical direction, and the second rotation axis b and the fourth rotation axis d can extend in the horizontal direction. In this way, the first rotation arm 3, the second rotation arm 4, the transition arm 5 and the vehicle door 300 as a whole can rotate around the vertical axis in the horizontal plane, and the vehicle door 300 can rotate around the horizontal axis in the vertical direction. By combining the rotation actions in the horizontal and vertical directions, the vehicle door 300 can be opened upward and outward at the same time, that is, opened obliquely upward. It can be understood that when closing the vehicle door 300, the rotation directions of the first rotation arm 3, the second rotation arm 4, the transition arm 5 and the vehicle door 300 are opposite.

[0049] Alternatively, the first rotation axis a and the third rotation axis c can both extend in the horizontal direction, and the second rotation axis b and the fourth rotation axis d can extend in the vertical direction. In this way, the first rotation arm 3, the second rotation arm 4, the transition arm 5 and the vehicle door 300 as a whole can rotate around the horizontal axis in the vertical plane, and the vehicle door 300 can rotate around the vertical axis in the horizontal plane. By combining the rotation actions in the horizontal and vertical directions, the vehicle door 300 can be opened upward and outward at the same time, that is, opened obliquely upward. It can be understood that when closing the vehicle door 300, the rotation directions of the first rotation arm 3, the second rotation arm 4, the transition arm 5 and the vehicle door 300 are opposite.

[0050] In some embodiments, reference Figure 2-Figure 4 as well as Figure 6-Figure 8The door hinge mechanism 100 may further include: a vehicle body fixed leaf base 1 and a vehicle door fixed leaf base 2. Specifically, the vehicle body fixed leaf base 1 is connected to the vehicle body 200, and the vehicle door fixed leaf base 2 may be connected to the vehicle door 300. The vehicle body fixed leaf base 1 may be formed into a vertically arranged plate shape, and the vehicle door fixed leaf base 2 may be formed into a vertically arranged plate shape. It can be understood that the structure of the vehicle body fixed leaf base 1 is adapted to the vehicle body 200, and the structure of the vehicle door fixed leaf base 2 is adapted to the vehicle door 300.

[0051] Among them, the vehicle body fixed leaf base 1 is provided with a first fixed arm 11 and a second fixed arm 12, the first fixed arm 11 is rotatably connected to one end of the first rotating arm 3, the second fixed arm 12 is rotatably connected to one end of the second rotating arm 4, and the door fixed leaf base 2 is provided with a third fixed arm 21 and a fourth fixed arm 22, the third fixed arm 21 is rotatably connected to the other end of the first rotating arm 3, and the fourth fixed arm 22 is rotatably connected to the other end of the transition arm 5. In this way, by providing the door fixed leaf base 2 and the door fixed leaf base 2, it is possible to avoid directly providing a structure connected to the door hinge mechanism 100 on the vehicle body 200 and the door 300, thereby helping to simplify the structure of the door 300 and the vehicle body 200. It is also possible to avoid directly damaging the structure of the vehicle body 200 and the door 300 when the hinge mechanism is damaged, and the replaceability is strong, which is conducive to later maintenance. At the same time, it is also helpful to reduce the requirements of the door hinge mechanism 100 on the model and structure matching of the vehicle body 200 and the door 300. It can be directly used in different vehicle body 200 and door 300 structures, and can share the door 300 and vehicle body 200 structure with ordinary hinges, thereby expanding the scope of application.

[0052] In a specific example, refer to Figure 2 and Figure 6 The vehicle body fixing base 1 and the vehicle body 200 are detachably connected, such as by bolts, and the vehicle door fixing base 2 and the vehicle door 300 are detachably connected, such as by bolts. In this way, the connection structure is simple and easy to assemble.

[0053] Further, refer to Figure 3 The first fixed arm 11 is connected to one end of the first rotating arm 3 through the pin 7, the second fixed arm 12 is connected to one end of the second rotating arm 4 through the pin 7, the third fixed arm 21 is connected to the other end of the first rotating arm 3 through the pin 7, and the fourth fixed arm 22 is connected to the other end of the transition arm 5 through the pin 7. In this way, the connection structure is relatively simple and easy to assemble, disassemble and maintain.

[0054] Of course, the present invention is not limited to this. The rotational matching structure of any pair of the first fixed arm 11 and the first rotating arm 3, the second fixed arm 12 and the second rotating arm 4, the third fixed arm 21 and the first rotating arm 3, and the fourth fixed arm 22 and the transition arm 5 can also be a ball joint or other pivot structure, and any pair of rotational matching structures can be reasonably selected according to actual needs.

[0055] In some embodiments, in combination Figure 3 or Figure 4 as well as Figure 7 and Figure 8 The first fixed arm 11 and the second fixed arm 12 are arranged at intervals and parallel to each other in the up-down direction, the first fixed arm 11 is located on the upper side of the second fixed arm 12, the relative position between the first rotating arm 3 and the second rotating arm 4 is adapted to the relative position between the first fixed arm 11 and the second fixed arm 12, and the relative position between the third fixed arm 21 and the fourth fixed arm 22 is adapted to the relative position between the first rotating arm 3 and the second rotating arm 4. In this way, mutual interference between the first fixed arm 11, the second fixed arm 12, the first rotating arm 3, the second rotating arm 4, the third fixed arm 21 and the fourth fixed arm 22 can be prevented, and the overall structural layout and movement form of the door hinge mechanism 100 can be made simpler, reducing the space occupied by the door hinge mechanism 100, reducing the volume, and reducing the weight.

[0056] For example Figure 4 As shown, the first fixed arm 11 and the second fixed arm 12 can be roughly formed into a horizontal plate with a V-shaped outer contour. The first fixed arm 11 and the second fixed arm 12 are perpendicular to the vehicle body fixed page base 1, and the width of the first fixed arm 11 and the second fixed arm 12 gradually decreases in the direction perpendicular to and away from the vehicle body fixed page base 1. The first fixed arm 11 and the second fixed arm 12 are arranged at intervals in the up-down direction and are parallel to each other, and the first fixed arm 11 is located on the upper side of the second fixed arm 12. Correspondingly, the first rotating arm 3 and the second rotating arm 4 are parallel to each other, and the first rotating arm 3 is located on the upper side of the second rotating arm 4. The third fixed arm 21 can be arranged at intervals in the up-down direction with the fourth fixed arm 22, and the third fixed arm 21 is located on the upper side of the fourth fixed arm 22. In this way, the overall structural layout and movement form of the door hinge mechanism 100 can be made simpler, and the first fixed arm 11, the second fixed arm 12, the first rotating arm 3, the second rotating arm 4, the third fixed arm 21 and the fourth fixed arm 22 can be prevented from interfering with each other, and the assembly efficiency can also be improved.

[0057] According to some embodiments of the present invention, the third fixing arm 21 and the fourth fixing arm 22 are integrally formed. Figure 3As shown, the third fixed arm 21 and the fourth fixed arm 22 can be roughly formed into a vertical plate with a V-shaped outer contour, and the third fixed arm 21 and the fourth fixed arm 22 are both perpendicular to the door fixing base 2, and in the direction away from the door fixing base 2, the width of the first fixed arm 11 and the second fixed arm 12 gradually decreases, and in the up and down directions, the third fixed arm 21 and the fourth fixed arm 22 can be connected and are in the same vertical plane, so that the distance between the two pivot connection points of the door 300 and the door hinge mechanism 100 is relatively close, which can make the overall structure of the door hinge mechanism 100 compact, which is beneficial to reduce the space occupied by the door hinge mechanism 100. In addition, the overall structural strength can also be enhanced.

[0058] Further, refer to Figure 3 and Figure 7 The first rotation axis a and the third rotation axis c both extend in the vertical direction, the second rotation axis b and the fourth rotation axis d both extend in the horizontal direction, in the direction perpendicular to the vehicle body fixed page base 1, the length of the second fixed arm 12 is greater than the length of the first fixed arm 11, so that the projection of the first rotation axis a in the reference plane and the projection of the second rotation axis b in the reference plane are staggered with each other, the rotation trajectory of the first rotating arm 3 and the rotation trajectory of the second rotating arm 4 are parallel to each other in the reference plane, the second rotating arm 4 and the transition arm 5 have a first rotation center point, the fourth fixed arm 22 and the transition arm 5 have a second rotation center point, the distance between the first rotation center point and the second rotation center point is the same as the distance between the rotation trajectory of the first rotating arm 3 and the rotation trajectory of the second rotating arm 4, and the reference plane is parallel to the horizontal plane.

[0059] Combination Figure 3 and Figure 4 or Figure 7 and Figure 8 Since the length of the second fixed arm 12 is greater than that of the first fixed arm 11, in a reference plane parallel to the horizontal plane, the connection point of the second fixed arm 12 and the second rotating arm 4 is located on the side of the first fixed arm 11 and the first rotating arm 3 that is away from the door fixed page base 2, that is, the projection of the first rotation axis a in the reference plane and the projection of the second rotation axis b in the reference plane are staggered in a direction perpendicular to the vehicle body fixed page base 1.

[0060] The first rotating arm 3 can be formed roughly in an L shape, and the first rotating arm 3 has a first section 31 and a second section 32 connected, the second section 32 and the first section 31 form an angle greater than ninety degrees, one end of the first section 31 is connected to the first fixed arm 11, and one end of the second section 32 is connected to the third fixed arm 21. The second rotating arm 4 can also be formed roughly in an L shape, and the second rotating arm 4 has a third section 41 and a fourth section 42, the third section 41 and the fourth section 42 form an angle greater than ninety degrees, one end of the third section 41 is connected to the second fixed arm 12, and one end of the fourth section 42 is connected to the transition arm 5. In the reference plane parallel to the horizontal plane, the projection of the third section 41 and the projection of the first section 31 are parallel to each other, and the projection of the fourth section 42 and the projection of the second section 32 are parallel to each other, so that the rotation trajectory of the first rotating arm 3 and the rotation trajectory of the second rotating arm 4 are parallel to each other in the reference plane, so that the first rotating arm 3 and the second rotating arm 4 rotate synchronously around the vertical axis in the horizontal plane. The distance between the first rotation center point and the second rotation center point in the reference plane is equal to the distance between the rotation track of the first rotating arm 3 and the rotation track of the second rotating arm 4 in the reference plane, so that the door 300 can rotate in the vertical plane around the horizontal axis relative to the first rotating arm 3 and the second rotating arm 4 at the same time. As a result, the movement of the door 300 is smoother.

[0061] Optionally, the first section 31 and the second section 32 may have a smooth transition, and the third section 41 and the fourth section 42 may have an arc transition.

[0062] Furthermore, the projection of the first rotation axis a on the reference plane, the projection of the third rotation axis c on the reference plane and the connecting line of the second rotation center point form a triangle, which is helpful to improve the overall structural stability of the door hinge mechanism 100.

[0063] According to some embodiments of the present invention, reference Fig. 9 The other end of the transition arm 5 and the second rotating arm 4 can be connected through a fisheye bearing or a ball head 8, so that the transition arm 5 can rotate around the axis and can also swing inward and outward to adapt to the angle changes in various directions during the movement of the door 300.

[0064] In some embodiments, reference Figure 2 and Figure 6The door hinge mechanism 100 further includes: a driving member 6, the driving member 6 includes an electric support rod, one end of the electric support rod is rotatably connected to the vehicle body 200, and the other end of the electric support rod is rotatably connected to the vehicle door 300, so as to realize the electric drive of the vehicle door 300 to open or close. For example, one end of the electric support rod can be connected to the vehicle body 200 through the vehicle body fixed page base 1, and the other end of the electric support rod can be connected to the vehicle door 300 by connecting to the vehicle door fixed page base 2. Optionally, the two ends of the electric support rod are respectively connected to the vehicle body 200 and the vehicle door 300 through the ball head 8, so that the electric support rod can adapt to the angle changes in all directions during the rotation of the vehicle door 300, and the two ends of the electric support rod have a drop in the height direction, so that the starting action of the electric support rod during the opening or closing process of the vehicle door 300 can be more labor-saving and smooth.

[0065] Reference below Figure 1-Figure 10 A vehicle 1000 according to an embodiment of the second aspect of the present invention is described.

[0066] The vehicle 1000 according to the embodiment of the present invention includes the door hinge mechanism 100 for the vehicle 1000 in the above embodiment.
