[0107] As Figures 1 to 11As shown, the application provides a hinge for driving a vehicle door 201 to approach or move away from a vehicle body. The hinge comprises a base 101, a first connecting rod 102, a second connecting rod 105, a mounting seat 107, and a rotating mechanism. The base 101 is used to be connected to the vehicle body. A first end of the first connecting rod 102 is rotatably connected to the base 101 around a first rotation shaft 103. A first end of the second connecting rod 105 is rotatably connected to the base 101 around a second rotation shaft 104. The mounting seat 107 is rotatably connected to a second end of the first connecting rod 102 around a third rotation shaft 106 and rotatably connected to a second end of the second connecting rod 105 around a fourth rotation shaft 110, so that the mounting seat 107 can move between a retracted position and an extended position relative to the base 101. The vehicle door 201 is connected to the mounting seat 107, so that the vehicle door 201 moves synchronously with the mounting seat 107. The rotating mechanism is connected to the mounting seat 107, and the vehicle door 201 is rotatably connected to the mounting seat 107. An input end of the rotating mechanism is connected to the vehicle door 201, and an output end of the rotating mechanism is connected to the second end of the second connecting rod 102, so that the vehicle door 201 rotates synchronously with the second connecting rod 102.
[0108] In some embodiments of the application, the rotating mechanism comprises a first steering shaft 108, a second steering shaft 114, and a rotating assembly. The first steering shaft 108 is fixedly connected to the second end of the second connecting rod 105, and the first steering shaft 108 is rotatably connected to the mounting seat 107 around a fifth axis 301, so that the first steering shaft 108 rotates synchronously with the second connecting rod 105. The second steering shaft 114 is rotatably connected to the mounting seat 107 around a sixth axis 302, and the second steering shaft 114 is fixedly connected to the vehicle door 201. The second steering shaft 114 can rotate the vehicle door 201 around the sixth axis 302, so that the vehicle door 201 rotates synchronously with the second steering shaft 114. The rotating assembly is connected to the first steering shaft 108 and the second steering shaft 114, so that the first steering shaft 108 rotates around the fifth axis 301 while the second steering shaft 114 rotates around the sixth axis 302. In the application, the first connecting rod 102, the second connecting rod 105, the base 101, and the mounting seat 107 are configured as a parallel four-bar linkage structure, which plays a role in supporting the vehicle door 201 and realizing the combined translation movement of the vehicle door 201 in the Y direction and the Z direction, so that the mounting seat 107 can move between the retracted position and the extended position. By changing the transmission angle through the rotating mechanism, the rotating movement of the vehicle door 201 in the X direction is realized. The first steering shaft 108 in the rotating mechanism is linked with the second connecting rod 105, so that the rotating mechanism can act simultaneously when the connecting rod mechanism acts. The linkage of the two groups of mechanisms in the application improves the motion stability and structural compactness while reducing the manufacturing cost.
[0109] As Figure 5As shown, in some embodiments of the present application, the mounting base 107 is configured as a bent structure, and comprises a first mounting base 1071, a second mounting base 1072 and a third mounting base 1073 connected in sequence, the first mounting base 1071 and the third mounting base 1073 are inclined to the second mounting base 1072 and located on one side of the second mounting base 1072. Thus, the first mounting base 1071, the second mounting base 1072 and the third mounting base 1073 are configured as a concave mounting portion. The first mounting base 1071 is hingedly connected with the first connecting rod 102, the second connecting rod 105 and the first steering shaft 108 respectively; preferably, the hinge points of the first connecting rod 102, the second connecting rod 105 and the first steering shaft 108 on the first mounting base 1071 are located on a horizontal plane. The third mounting base 1073 is used for mounting the second steering shaft 114. As known from the foregoing, the first mounting base 1071 and the third mounting base 1073 are inclined to the second mounting base 1072. Preferably, the included angle between the first mounting base 1071 and the second mounting base 1072 is 135°. The included angle between the third mounting base 1073 and the second mounting base 1072 is 135°. Thus, the first mounting base 1071 and the third mounting base 1073 can be perpendicular. Further, the first steering shaft 108 and the second steering shaft 114 can be perpendicular. Thus, the steering rotation of the hinge is realized.
[0110] In some embodiments of the present application, the base 101 is provided with a vertical plate 1011, the first connecting rod 102 and the second connecting rod 105 are rotatably connected with the vertical plate 1011 respectively, and the first connecting rod 102 and the second connecting rod 105 are arranged on both sides of the vertical plate 1011. The vertical plate 1011 is an element of support and fixing structure, by setting appropriate position and angle, it can provide stable support, so that the movement range of the connecting rod mechanism is more reasonable.
[0111] In some embodiments of the present application, the line between the two hinge points of the first connecting rod 102 is parallel to the line between the two hinge points of the second connecting rod 105, and the line between the two hinge points of the first mounting base 107 is perpendicular to the mounting surface 601 of the base. That is, the hinge in the present application is a parallel four-bar linkage mechanism. Figure 3 As shown, the first connecting rod center line 501 in the retracted state is parallel to the first connecting rod center line 502 in the extended state. The line 503 connecting the first shaft and the second shaft is parallel to the line 504 connecting the third shaft and the fourth shaft.
[0112] The parallel four-bar linkage keeps the relative parallel position relationship between the links during the movement, so as to realize stable and smooth movement track. The force is evenly distributed and supported by the links during the movement, and the parallel four-bar linkage has high load bearing capacity. At the same time, due to the parallel arrangement between different links, the parallel four-bar linkage can provide a larger working space, so that the mounting seat 107 has a longer distance between the retracted position and the extended position. In the embodiment, the mounting surface 601 of the base is the vehicle body. The third mounting seat 107 is parallel to the mounting surface 601 of the base. Therefore, the second steering shaft 114 mounted on the third mounting seat 107 can be arranged perpendicular to the mounting surface 601 of the base, so that the door 201 rotates around the axis perpendicular to the mounting surface 601 of the base.
[0113] In some embodiments of the present application, the fifth axis 301 and the sixth axis 302 always intersect at a point. When the fifth axis 301 and the sixth axis 302 always intersect at the same point, the overall stability of the hinge structure can be increased, so that the movement of the door 201 is more stable. By making the fifth axis 301 and the sixth axis 302 intersect at the same point, the operation and control of the hinge can be more convenient, and the efficiency and convenience of opening and closing the door 201 are improved.
[0114] In some embodiments of the present application, the end of the rotating assembly connected with the first steering shaft 108 is perpendicular to the rotation axis of the first steering shaft 108 (i.e. the ninth axis 305) and the rotation axis of the first steering shaft 108 relative to the mounting seat 107 (i.e. 301).
[0115] In some embodiments of the present application, the rotating assembly includes a first universal joint rod 109, a third universal joint rod 112, and a second universal joint rod 111. The first end of the first universal joint rod 109 is rotatably connected to the second end of the first steering shaft 108 around the seventh axis 303. The first end of the third universal joint rod 112 is rotatably connected to the first end of the second steering shaft 114 around the eighth axis 304. The first end of the second universal joint rod 111 is rotatably connected to the second end of the first universal joint rod 109 around the ninth axis 305, and the second end of the second universal joint rod 111 is rotatably connected to the second end of the third universal joint rod 112 around the tenth axis 306. By associating the rotating mechanism with the adjacent links, these universal joint rods can change the transmission angle while the links are moving. Preferably, the door 201 can rotate in the X direction relative to the vehicle body. The design of these universal joint rods makes the connection between the rotating mechanism and the links more stable, thereby enhancing the stability and reliability of the entire hinge structure.
[0116] As Figure 9In the closed state of the door 201, the first steering shaft 108, the first universal joint rod 109, the second universal joint rod 111 and the third universal joint rod 112 share a symmetric median plane, but will produce spatial rotation movement relative to each other during the opening and closing process. Figure 10 and Figure 11 are respectively the +X direction views of the universal joint link drive hinge at the closing and opening time, the first link 102 and the second link 105 simultaneously rotate around the base 101 to swing the door 201 by an opening angle (i.e. the angle 505 between the first link 102 and the vertical plane in the retracted state), the position of the first link center line 501 in the retracted state is rotated to the first link center line 501' in the extended state after the door 201 is opened, and the second steering shaft 114 drives the door 201 to rotate 90 degrees in the -Y direction (i.e. outward) and the +Z direction (i.e. upward) at the same time to open. In the closed state, the first link 102 center line and the second link 105 center line are arranged as parallel to the mounting surface 601 of the base or at the smallest angle to save the Y direction arrangement space as much as possible. In the closed state of the door 201, the seventh axis 303 is parallel to the eighth axis 304. In the open state of the door 201, the seventh axis 303 is not parallel to the eighth axis 304. The ninth axis 305 is parallel to the tenth axis 306. The fifth axis 301, the seventh axis 303 and the ninth axis 305 intersect at the same point. The sixth axis 302, the eighth axis 304 and the tenth axis 306 intersect at the same point. The layout of the hinge structure is optimized, and the transmission and rotation movement are more smooth. At the same time, this layout also enhances the structural firmness and stability of the overall system. Preferably, the door 201 can rotate relative to the vehicle body in the X direction.
[0117] As Figure 6 shown, in some embodiments of the present application, the second universal joint rod 111 is configured as a bent structure and includes a first bent rod 1111, a second bent rod 1112 and a third bent rod 1113 connected in sequence, the first bent rod 1111 and the third bent rod 1113 are inclined to the second bent rod 1112, and the first bent rod 1111 and the third bent rod 1113 are located on different sides of the second bent rod 1111. The first bent rod 1111 is hingedly connected to the first universal joint rod 109. The third bent rod 1113 is hingedly connected to the third universal joint rod 112.
[0118] In some embodiments of the present application, the first bending rod 1111 is parallel to the third bending rod 1113. The first bending rod 1111 is perpendicular to the second bending rod 1112. The third bending rod 1113 is perpendicular to the second bending rod 1112. Further, the first bending rod 1111 is perpendicular to the ninth axis 305, and the third bending rod 1113 is perpendicular to the tenth axis 306. The parallel arrangement of the first bending rod 1111 and the third bending rod 1113 allows the hinge system to have better movement flexibility, allowing different components to move in mutually perpendicular or parallel directions, providing more movement variations and options, which is conducive to achieving the control of the vehicle door 201 approaching or moving away from the vehicle body. The mutually perpendicular arrangement can achieve balanced distribution of stress, reducing the possibility of uneven stress between components, and helping to improve the overall stability and durability of the hinge system. And through the arrangement of the bending structure of the second universal joint rod 111, the space is reasonably utilized, and the compactness of the layout is improved.
[0119] In some embodiments of the present application, a driving member is also provided to ensure smooth operation and improve the holding performance of the vehicle door 201. The driving member is used to drive one of the following movements: driving the first connecting rod 102 to rotate around the first rotating shaft 103; driving the second connecting rod 105 to rotate around the second rotating shaft 104; driving the mounting seat 107 to rotate around the third rotating shaft 106; driving the mounting seat 107 to rotate around the fourth rotating shaft 110; driving the first steering shaft 108 to rotate around the fifth axis 301; and driving the second steering shaft 114 to rotate around the sixth axis 302. It can be understood that through the arrangement of the foregoing scheme, the components are mutually constrained and act cooperatively to form a closed system, so that when one component is stressed or driven by the outside, it will transmit the force or movement to other components through the hinge, thereby achieving the movement of the entire mechanism.
[0120] As an implementable embodiment, the driving member is a structure that can axially extend and retract, with a first end connected to the vehicle body in the axial direction and a second end connected to one of the first connecting rod 102 and the second connecting rod 105 to directly drive the first connecting rod 102 or the first connecting rod 105 to rotate relative to the base 101, thereby driving the vehicle door 201 to move. In this embodiment, the rotation angle of the first connecting rod 102 and the second connecting rod 105 is small, and the transmission efficiency of the entire hinge mechanism is high.
[0121] As another implementable embodiment, the second steering shaft 114 is provided with a body portion and a mounting portion. The body portion can rotate around the sixth axis 302, and the mounting portion is fixed with the body portion and rotates with the rotation of the body portion. The mounting seat 107 is provided with a brace rod mounting hole 401 for connecting a ball pin support of an electric spring, a pneumatic spring or a balance spring to provide driving for the opening and closing of the vehicle door 201.
[0122] In the implementation of the present application, Figures 10-11As shown, during the opening or closing process of the door 201, the electric spring, pneumatic spring, or balance spring will drive the second steering shaft 114 connected to it, causing the door 201 to rotate. At the same time, this will cause the first link 102 and the second link 105 to translate outward and upward, ultimately achieving the effect shown in the attached diagram.
