[0107] like Figures 1 to 11As shown, the present application provides a hinge for driving a vehicle door 201 to move closer to or away from a vehicle body. It includes 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. The first end of the first connecting rod 102 is rotatably connected to the base 101 around a first rotating shaft 103. The first end of the second connecting rod 105 is rotatably connected to the base 101 around a second rotating shaft 104. The mounting seat 107 is rotatably connected to the second end of the first connecting rod 102 around a third rotating shaft 106, and is rotatably connected to the second end of the second connecting rod 105 around a fourth rotating shaft 110, so that the mounting seat 107 can move between a retracted position and an extended position relative to the base 101. And the vehicle door 201 is connected to the mounting seat 107 so that the vehicle door 201 and the mounting seat 107 move synchronously. The rotating mechanism is connected to the mounting base 107 , and the vehicle door 201 is rotatably connected to the mounting base 107 , the input end of the rotating mechanism is connected to the vehicle door 201 , and the output end of the rotating mechanism is connected to the second end of the second connecting rod 102 , so that the vehicle door 201 and the second connecting rod 102 rotate synchronously.
[0108] In some embodiments of the present application, the rotating mechanism includes 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 the fifth axis 301, so that the first steering shaft 108 and the second connecting rod 105 rotate synchronously. The second steering shaft 114 is rotatably connected to the mounting seat 107 around the sixth axis 302, and the second steering shaft 114 is fixedly connected to the vehicle door 201, and 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 when the second steering shaft 114 rotates around the sixth axis 302, the first steering shaft 108 rotates around the fifth axis 301. In the present application, the first connecting rod 102, the second connecting rod 105, the base 101 and the mounting seat 107 are constructed as a parallel four-link structure, which plays a load-bearing role for the vehicle door 201 and realizes the combined translational 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. The transmission angle is changed by the rotating mechanism to realize the rotational movement of the vehicle door 201 in the X direction. The first steering shaft 108 in the rotating mechanism is linked with the second connecting rod 105, so that when the connecting rod mechanism is in motion, the rotating mechanism can be moved at the same time. The present application links the two groups of mechanisms, which reduces the manufacturing cost while improving the motion stability and the compactness of the structure.
[0109] like Figure 5As shown, in some embodiments of the present application, the mounting seat 107 is configured as a bending structure, and includes a first mounting seat 1071, a second mounting seat 1072 and a third mounting seat 1073 connected in sequence, and the first mounting seat 1071 and the third mounting seat 1073 are both inclined to the second mounting seat 1072 and are located on one side of the second mounting seat 1072. Thus, the first mounting seat 1071, the second mounting seat 1072, and the third mounting seat 1073 are configured as a concave mounting portion. Among them, the first mounting seat 1071 is hinged to 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, the first steering shaft 108 and the first mounting seat 1071 are located in a horizontal plane. The third mounting seat 1073 is used to install the second steering shaft 114. As can be seen from the above, the first mounting seat 1071 and the third mounting seat 1073 are both inclined to the second mounting seat 1072. Preferably, the angle between the first mounting seat 1071 and the second mounting seat 1072 is 135°. The angle between the third mounting seat 1073 and the second mounting seat 1072 is 135°. Therefore, the first mounting seat 1071 and the third mounting seat 1073 can be made perpendicular. Further, the first steering shaft 108 and the second steering shaft 114 can be made perpendicular. Thus, the steering rotation of the hinge is achieved.
[0110] In some embodiments of the present application, the base 101 is provided with a vertical plate 1011, and the first connecting rod 102 and the second connecting rod 105 are rotatably connected to 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, as a supporting and fixing structural element, can provide stable support by setting a suitable position and angle, so that the motion 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 link 102 is parallel to the line between the two hinge points of the second link 105, and the line between the two hinge points of the first mounting seat 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. Figure 3 As shown, the center line 501 of the first connecting rod in the retracted state is parallel to the center line 502 of the first connecting rod in the extended state. The connecting line 503 of the first rotating shaft and the second rotating shaft is parallel to the connecting line 504 of the third rotating shaft and the fourth rotating shaft.
[0112] During the movement of the parallel four-bar linkage, each link maintains a relatively parallel positional relationship, so that a stable and smooth motion trajectory can be achieved; the links are evenly distributed and support each other during the movement, and the parallel four-bar linkage has a high load-bearing capacity. At the same time, due to the parallel arrangement of 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 this 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 installed 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 an 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 one 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 hinge can be operated and controlled more conveniently, thereby improving the efficiency and convenience of opening and closing the door 201.
[0114] In some embodiments of the present application, the end of the rotating assembly connected to 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 base 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 connecting rod, these universal joint rods can change the transmission angle while the connecting rod moves. Preferably, the door 201 can rotate relative to the vehicle body in the X direction. The design of these universal joint rods makes the connection between the rotating mechanism and the connecting rod more stable, thereby enhancing the stability and reliability of the entire hinge structure.
[0116] like Fig. 9When the door 201 is closed, 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 symmetrical midplane, but they will generate spatial rotational motions with each other during the opening and closing process. Fig.10 and attached Fig.11 They are respectively the +X direction view of the universal joint connecting rod driving the hinge at the closing and opening moments, the first connecting rod 102 and the second connecting rod 105 simultaneously rotate the swing arm door opening angle around the base 101 fixed axis (i.e., the angle 505 between the first connecting rod 102 and the vertical plane in the retracted state), the center line 501 of the first connecting rod in the retracted state rotates to the center line 501' of the first connecting rod in the extended state after the door is opened, and the second steering shaft 114 drives the door 201 to rotate 90 degrees while extending along the -Y direction (i.e., outside the vehicle) and the +Z direction (i.e., upward) to compound open. In the closed state, the center line of the first connecting rod 102 and the center line of the second connecting rod 105 are parallel to the mounting surface 601 of the base as much as possible or arranged at a minimum angle to save the Y direction layout space to the maximum extent. When the door 201 is closed, the seventh axis 303 is parallel to the eighth axis 304. When the door 201 is opened, 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 rotational movement are smoother. 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] like Figure 6 As shown, in some embodiments of the present application, the second universal joint rod 111 is constructed as a bending structure, and includes a first bending rod 1111, a second bending rod 1112, and a third bending rod 1113 connected in sequence, the first bending rod 1111 and the third bending rod 1113 are both inclined to the second bending rod 1112, and the first bending rod 1111 and the third bending rod 1113 are located on different sides of the second bending rod 1111. The first bending rod 1111 is hingedly connected to the first universal joint rod 109. The third bending 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 layout of the first bending rod 1111 and the third bending rod 1113 enables the hinge system to have better movement flexibility, allowing different components to move in mutually perpendicular or parallel directions, providing more movement changes and options, and facilitating the control of the door 201 approaching or moving away from the vehicle body. The mutually perpendicular layout can achieve balanced distribution of force, reduce the possibility of uneven stress between components, and help improve the overall stability and durability of the hinge system. And through the setting of the bending structure of the second universal joint rod 111, 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 door 201. The driving member is used for 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; driving the second steering shaft 114 to rotate around the sixth axis 302. It can be understood that through the arrangement of the above-mentioned scheme, the various components are mutually constrained and act in coordination to form a closed system, so that the hinge mechanism outputs a single action. Therefore, when a component is subjected to force or driven by the outside world, it will transmit this force or movement to other components through the hinge, thereby realizing the movement of the entire mechanism.
[0120] As a feasible implementation, the driving member is a structure that can be extended and retracted in the axial direction, and its first end in the axial direction is connected to the vehicle body, and its second end is connected to one of the first link 102 and the second link 105, so as to directly drive the first link 102 or the first link 105 to rotate relative to the base 101, thereby driving the vehicle door 201 to move. In this embodiment, the rotation angles of the first link 102 and the second link 105 are small, and the transmission efficiency of the entire hinge mechanism is high.
