The embodiments described below by reference to the drawings are exemplary only, and are for the purpose of explanation of the present application, and should not be understood as a limitation of the present application.

[0051] The door hinge structure 1000 of the utility model embodiment is described below with reference to the drawings of the specification.

[0052] As shown in Figure 1 and Figure 2 , the door hinge structure 1000 according to the utility model embodiment comprises a mounting seat 100, a connecting arm 200 and a connecting assembly 300.

[0053] The mounting seat 100 is suitable for being mounted to the vehicle body. It can be understood here that the mounting seat 100 connects the vehicle body as the base of the door hinge structure 1000 to realize the cooperative connection of the door hinge structure 1000 and the vehicle body, the mounting seat 100 is used for supporting and fixing the door hinge structure 1000 structure, improving the positional stability of the door hinge structure 1000, ensuring the working performance of the door hinge structure 1000 to a certain extent, and the stable connection of the door hinge structure 1000 and the vehicle body can also ensure the stability of the vehicle body.

[0054] The connecting arm 200 is suitable for being mounted to the vehicle door. It can be understood here that the door hinge structure 1000 cooperatively connects with the vehicle door through the connecting arm 200, thereby realizing the cooperative connection of the door hinge structure 1000 with the vehicle body and the vehicle door respectively, that is, realizing the cooperative connection of the vehicle body and the vehicle door.

[0055] In some embodiments, the connecting arm 200 transmits force to the vehicle door as the force arm of the door hinge structure 1000, which is conducive to the opening and closing of the vehicle door and reduces the difficulty of opening and closing the vehicle door.

[0056] As shown in Figure 2 , Figure 3 and Figure 4 , the connecting assembly 300 comprises a ball pin unit 310, the ball pin unit 310 has a ball head 311 and a pin shaft 312 connected with each other, the ball head 311 is rotatably connected with the connecting arm 200, the pin shaft 312 is cooperatively connected with the mounting seat 100 through a limiting assembly 400 to realize the rotary connection of the mounting seat 100 and the connecting arm 200, and the limiting assembly 400 is used for limiting the displacement of the pin shaft 312 in the axial direction thereof.

[0057] Herein, the ball head 311 is rotatably connected to the connecting arm 200, and the pin shaft 312 is connected to the mounting seat 100 through the limiting assembly 400, so that the mounting seat 100 and the connecting arm 200 are rotatably connected, and the rotation of the door and the vehicle body is realized, and the difficulty of opening and closing the door relative to the vehicle body is reduced.

[0058] Therefore, the above can also be understood as that the connecting assembly 300 connects the mounting seat 100 and the connecting arm 200 as intermediate parts, and the three parts together constitute the whole door hinge structure 1000.

[0059] It is worth noting that the pin shaft 312 is connected to the mounting seat 100 through the limiting assembly 400, and the limiting assembly 400 is arranged to limit the displacement of the pin shaft 312 in the axial direction of the pin shaft 312, so as to improve the position stability of the pin shaft 312. Since the pin shaft 312 and the ball head 311 are connected to each other, the displacement of the ball head 311 in the axial direction of the pin shaft 312 can be limited, and finally the axial movement of the ball pin unit 310 is limited, and the position stability of the ball pin unit 310 is improved. Since the mounting seat 100 and the connecting arm 200 are rotatably connected through the ball pin unit 310, the shaking of the connecting arm 200 relative to the mounting seat 100 is limited, and the shaking of the door relative to the vehicle body is limited, so that the door can be stably opened and closed, and the shaking of the door affects the smooth running of the whole vehicle to a certain extent, and the quality of the door is enhanced.

[0060] At the same time, directly limiting the shaking of the door by the limiting assembly 400 can also simplify the limiting structure of the door hinge structure 1000, reduce the processing cost of the door hinge structure 1000, and make the process of the door hinge structure 1000 simple.

[0061] From the above structure, it can be seen that the door hinge structure 1000 of the embodiment of the present application can limit the displacement of the pin shaft 312 in the axial direction thereof by arranging the limiting assembly 400, so as to prevent the axial movement of the pin shaft 312, thereby limiting the axial displacement of the ball pin unit 310, improving the stability of the ball pin unit 310 during movement, and further improving the stability of the connecting arm 200 relative to the mounting seat 100, that is, improving the position stability of the door relative to the vehicle body, avoiding the shaking of the door during opening or closing, and enhancing the quality of the door.

[0062] In addition, limiting the displacement of the door by the limiting assembly 400 can also simplify the limiting structure of the door hinge structure 1000 and reduce the processing cost of the door hinge structure 1000.

[0063] It can be understood that, compared with the prior art, the vehicle door hinge structure 1000 of the present application can not only prevent the vehicle door from shaking and improve the stability of the vehicle door, but also simplify the structure of the vehicle door hinge structure 1000.

[0064] In some embodiments, as Figure 4 As shown, the surface of the ball head 311 is arc-shaped, and the ball head 311 is rotatably connected to the connecting arm 200 so that the connecting arm 200 can achieve spatial movement under the action of external force, thereby realizing the rotational connection between the connecting arm 200 and the mounting seat 100.

[0065] In some embodiments, combined Figure 3 and Figure 4 As shown, the ball-pin unit 310 further includes a socket end cap 313 and a socket bushing 314. The connecting arm 200 is provided with a mounting groove, and the ball head 311 is mounted in the mounting groove via the socket bushing 314. This enables a rotational connection between the ball head 311 and the connecting arm 200, reduces the difficulty of connecting the ball head 311 and the connecting arm 200, and also reduces wear between the ball head 311 and the connecting arm 200, thereby extending the service life of the ball head 311 and the connecting arm 200.

[0066] Optionally, the ball socket end cap 313 is fixedly connected to the connecting arm 200 and the ball socket bushing 314, respectively. This achieves a fixed connection between the connecting arm 200 and the ball socket bushing 314, stabilizes the relative positions of the connecting arm 200 and the ball socket bushing 314, prevents the ball socket bushing 314 from moving, and makes the connection between the ball socket end cap 313 and the connecting arm 200 more secure, thereby improving the working performance of the ball socket bushing 314.

[0067] In some embodiments, the ball and socket end cap 313 is riveted to the connecting arm 200 .

[0068] In some embodiments, combined Figure 3 and Figure 6 As shown, the mounting base 100 is provided with a first limiting groove 110, and the pin 312 is movably provided in the first limiting groove 110. The first limiting groove 110 is also used to limit the swing of the pin 312. Particularly, by movably providing the pin 312 in the first limiting groove 110, the pin 312 is connected to the mounting base 100 and can also be moved relative to the mounting base 100 along the extension direction of the first limiting groove 110. In this way, when the connecting arm 200 rotates relative to the mounting base 100, the pin 312 can be driven to move, thereby preventing the pin 312 from hindering the rotation of the connecting arm 200 to a certain extent. That is, the connecting arm 200 can effectively rotate relative to the mounting base 100, thereby facilitating the opening and closing of the vehicle door and forming the vehicle door into a scissor door.

[0069] Alternatively, as Figure 6As shown, the first limiting groove 110 is formed as a first arc-shaped groove, and the extension direction of the first arc-shaped groove is designed based on the movement envelope of the pin shaft 312 when the connecting arm 200 rotates. It can be understood here that the extension direction of the first limiting groove 110 is formed as an arc shape.

[0070] At the same time, by limiting the swing of the pin shaft 312 through the first limiting groove 110, the position stability of the pin shaft 312 can be further improved, so as to limit the displacement of the connecting arm 200 relative to the mounting seat 100 by using the pin shaft 312, so as to limit the swing of the door relative to the vehicle body, so that the door can also be stably opened and closed.

[0071] That is, the first limiting groove 110 of the present application not only enables the pin shaft 312 to effectively move relative to the mounting seat 100 when the connecting arm 200 rotates relative to the mounting seat 100, but also limits the swing of the pin shaft 312, so that the pin shaft 312 can move in a predetermined direction, ensuring the position stability of the movement of the pin shaft 312, thereby ensuring the position stability of the mounting seat 100, so that the door can be effectively and stably connected to the vehicle body by using the mounting seat 100.

[0072] In some embodiments, the size of the first limiting groove 110 in the width direction thereof is equal to the outer diameter of the pin shaft 312, so as to limit the swing of the pin shaft 312 by using the first limiting groove 110, so that the pin shaft 312 can stably move along the extension direction of the first limiting groove 110, ensuring the position stability of the movement of the pin shaft 312.

[0073] Among them, the extension direction of the first limiting groove 110 is formed as an arc shape, and the width direction of the first limiting groove 110 can be understood as the direction perpendicular to the extension direction of the first limiting groove 110.

[0074] In some embodiments, as Figure 3As shown, the limiting assembly 400 comprises a first limiting piece 410 and a second limiting piece 420, the first limiting piece 410 and the second limiting piece 420 are arranged in the axial direction of the pin shaft 312, and the first limiting piece 410 and the second limiting piece 420 are fixedly connected with the pin shaft 312, and at least part of the mounting seat 100 is arranged between the first limiting piece 410 and the second limiting piece 420 and is in abutting cooperation with the first limiting piece 410 and the second limiting piece 420. In order to limit the relative displacement of the first limiting piece 410 and the second limiting piece 420 by the mounting seat 100, and then limit the displacement of the first limiting piece 410 and the second limiting piece 420 in the axial direction of the pin shaft 312 by the mounting seat 100, because the first limiting piece 410 and the second limiting piece 420 are fixedly connected with the pin shaft 312, so the displacement of the pin shaft 312 in the axial direction thereof can be limited by the mounting seat 100, the position stability of the pin shaft 312 is improved, the displacement of the connecting arm 200 relative to the mounting seat 100 is limited, and the purpose of limiting the shaking of the door relative to the vehicle body is achieved. The door can be stably opened and closed.

[0075] At the same time, by limiting the displacement of the pin shaft 312 in the axial direction thereof by the cooperation of the first limiting piece 410, the second limiting piece 420 and the mounting seat 100, the difficulty of limiting the pin shaft 312 can be reduced, and the structure of the limiting assembly 400 is simplified, thereby simplifying the limiting structure of the door hinge structure 1000 and reducing the processing cost of the door hinge structure 1000.

[0076] In the description of the utility model, the features limited by "first" and "second" can be explicitly or implicitly included one or more features, which are used to distinguish the description features and have no order and no difference.

[0077] In some embodiments, as shown, Figure 4 The first limiting piece 410 is a limiting protrusion, which is arranged on the pin shaft 312 and protrudes in the radial direction of the pin shaft 312, so that the limiting protrusion is opposite to the mounting seat 100 in the axial direction of the pin shaft 312. Therefore, the displacement of the pin shaft 312 in the axial direction thereof can be limited by the cooperation of the first limiting piece 410, the second limiting piece 420 and the mounting seat 100, and the difficulty of limiting the pin shaft 312 is reduced.

[0078] At the same time, by setting the first limiting piece 410 as a limiting protrusion, the forming difficulty of the first limiting piece 410 can be further reduced.

[0079] In some embodiments, the limiting protrusion can be integrally formed on the pin shaft 312, so that the limiting protrusion and the pin shaft 312 are formed as an integral piece, the connection difficulty of the limiting protrusion and the pin shaft 312 is reduced, the connection strength of the limiting protrusion and the pin shaft 312 is improved, and the position stability of the limiting protrusion is improved, thereby ensuring the working performance of the limiting protrusion to a certain extent.

[0080] In other embodiments, the limiting protrusion and the pin 312 can also be processed separately. That is, the limiting protrusion and the pin 312 are processed and formed separately, which reduces the difficulty of forming the limiting protrusion and the pin 312.

[0081] Among them, when the limiting protrusion and the pin shaft 312 are processed and formed separately, the limiting protrusion and the pin shaft 312 can be connected by welding, clamping or bolt connection.

[0082] In some embodiments, combined Figure 3 and Figure 4 As shown, the second limiting member 420 is a limiting plate, which is abutted against the side of the mounting base 100 facing away from the connecting arm 200 and facing the first limiting groove 110. One end of the pin 312 is connected to the ball head 311, and the other end of the pin 312 is disposed in the first limiting groove 110 and fixedly connected to the limiting plate. Specifically, by disposing the limiting plate directly opposite the first limiting groove 110, the limiting plate can be disposed directly opposite the pin 312. Thus, when the other end of the pin 312 is disposed in the first limiting groove 110, the pin 312 is easily fixedly connected to the limiting plate, thereby facilitating the use of the limiting plate to limit the displacement of the pin 312 in its axial direction.

[0083] In some embodiments, combined Figure 2 、 Figure 3 and Figure 4 As shown, the second limit member 420 stops at the side of the mounting seat 100 away from the connecting arm 200, and the first limit member 410 stops at the side of the mounting seat 100 toward the connecting arm 200, so as to achieve that at least part of the mounting seat 100 is arranged between the first limit member 410 and the second limit member 420 and stops and cooperates with the first limit member 410 and the second limit member 420, thereby reducing the difficulty of cooperation between the first limit member 410, the second limit member 420 and the mounting seat 100.

[0084] In some embodiments, combined Figure 4 and Figure 7 As shown, the limiting assembly 400 further includes a fastener 430, which is provided through the limiting plate and fixedly connected to the other end of the pin 312. This allows the limiting plate and the pin 312 to be fixedly connected, effectively preventing the pin 312 from moving in its axial direction.

[0085] At the same time, the use of the fastener 430 to achieve a fixed connection between the limiting plate and the pin shaft 312 can also reduce the difficulty of connecting the limiting plate and the pin shaft 312.

[0086] In some embodiments, the fastener 430 is a bolt, so that the fixed connection mode of the limiting plate and the pin shaft 312 is formed as a bolt connection, which not only can reduce the difficulty of the fixed connection of the limiting plate and the pin shaft 312, but also can make the connection of the pin shaft 312 and the limiting plate more firm, so that the pin shaft 312 can be effectively prevented from moving in the axial direction by using the limiting plate.

[0087] Of course, in other embodiments, the fastener 430 can be formed as a screw.

[0088] In some embodiments, as shown in Figure 3 and Figure 4 , the other end of the pin shaft 312 is provided with a threaded hole 450, and the fastener 430 is arranged in the limiting plate and fixedly connected in the threaded hole 450, so as to achieve the purpose of realizing the fixed connection of the limiting plate and the pin shaft 312 by using the fastener 430.

[0089] In some embodiments, as shown in Figure 3 and Figure 4 , the limiting assembly 400 further comprises a matching piece 440, which is fixedly connected to the side of the mounting seat 100 away from the connecting arm 200 and located between the limiting plate and the mounting seat 100, and the limiting plate and the matching piece 440 are in sliding fit. In the process of rotating the connecting arm 200 relative to the mounting seat 100, the pin shaft 312 can drive the limiting plate to move in the first limiting groove 110, so as to avoid the limiting plate from hindering the movement of the pin shaft 312 along the extension direction of the first limiting groove 110, so that the connecting arm 200 can be effectively rotated relative to the mounting seat 100, facilitating the opening and closing of the vehicle door, and making the vehicle door into a scissor door.

[0090] At the same time, by arranging the matching piece 440 between the limiting plate and the mounting seat 100, the contact between the limiting plate and the mounting seat 100 can be avoided, so that when the pin shaft 312 drives the limiting plate to move along the extension direction of the first limiting groove 110, the friction between the mounting seat 100 and the limiting plate can be avoided, prolonging the service life of the mounting seat 100.

[0091] In some embodiments, as shown in Figure 4 , the side of the limiting plate facing the matching piece 440 is provided with a protruding part 421, and the protruding part 421 and the matching piece 440 are in sliding fit. The arrangement of the protruding part 421 can reduce the contact area of the limiting plate and the matching piece 440, on the one hand, reducing the wear of the matching piece 440 when the limiting plate moves, prolonging the service life of the matching piece 440, and on the other hand, reducing the friction between the limiting plate and the matching piece 440, making the sliding fit between the limiting plate and the matching piece 440 more smooth, so that the movement of the pin shaft 312 in the first limiting groove 110 is more smooth, which is beneficial to improve the response speed when the vehicle door is opened and closed.

[0092] In some embodiments, the protrusion 421 can be integrally formed on the limiting plate, such that the protrusion 421 and the limiting plate are formed as an integral piece, reducing the difficulty of connecting the protrusion 421 and the limiting plate, and improving the connection strength of the protrusion 421 and the limiting plate, thereby improving the position stability of the protrusion 421, and to some extent, ensuring the working performance of the protrusion 421.

[0093] In other embodiments, the protrusion 421 and the limiting plate can also be separately processed. That is, the protrusion 421 and the limiting plate are separately processed and formed, reducing the difficulty of forming the protrusion 421 and the limiting plate.

[0094] Wherein, after the protrusion 421 and the limiting plate are separately processed and formed, the connection mode of the protrusion 421 and the limiting plate can be welding, clamping or bolt connection, etc.

This can realize the rotatable connection between the first connecting rod 510 and the second connecting rod 520, and reduce the connection difficulty of the first connecting rod 510 and the second connecting rod 520.

This can realize the rotatable connection between the first end of the first connecting rod 510, the first end of the second connecting rod 520 and the connecting pin 530, and reduce the connection difficulty of the first connecting rod 510, the second connecting rod 520 and the connecting pin 530.

It can be understood that the first fixing member 531 is detachably connected with the connecting pin 530, or the second fixing member 532 is detachably connected with the connecting pin 530, or the first fixing member 531 and / or the second fixing member 532 are detachably connected with the connecting pin 530, so as to sleeve the first connecting rod 510 and the second connecting rod 520 between the first fixing member 531 and the second fixing member 532, so that the first connecting rod 510 and the second connecting rod 520 can be fixed by the first fixing member 531 and the second fixing member 532, so that the first connecting rod 510 and the second connecting rod 520 can be effectively arranged on the connecting pin 530, and the rotation connection of the first connecting rod 510 and the second connecting rod 520 can be effectively realized by the connecting pin 530, and the rotation connection difficulty of the first connecting rod 510 and the second connecting rod 520 is reduced.

[0103] In some embodiments, as shown in Figure 1 and Figure 2 The first connecting rod 510 is arranged on the side of the second connecting rod 520 away from the mounting base 100, and the mounting base 100 is provided with a limiting table 130 for supporting the first connecting rod 510 to limit and constrain the axial displacement of the first connecting rod 510, thereby improving the stability of the first connecting rod 510 and ensuring the working performance of the first connecting rod 510 to a certain extent.

[0104] In some embodiments, the first connecting rod 510 contacts the limiting table 130 through a gasket, thereby reducing the wear between the first connecting rod 510 and the limiting table 130.

[0105] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 6As shown, the mounting base 100 is provided with a second limiting groove 120, and the connecting pin 530 is movably arranged in the second limiting groove 120, and the second limiting groove 120 is also used to limit the swing of the connecting pin 530. Among them, by movably arranging the connecting pin 530 in the second limiting groove 120, the first end of the first connecting rod 510 and the first end of the second connecting rod 520 can be movably matched with the mounting base 100, so that in the process of rotating the connecting arm 200 relative to the mounting base 100, the connecting arm 200 can effectively drive the pin shaft 312 to move, to a certain extent, to avoid the pin shaft 312 hindering the rotation of the connecting arm 200, that is, to make the connecting arm 200 can effectively rotate relative to the mounting base 100, facilitate the realization of the opening and closing of the door, and make the door form a scissor door.

[0106] Optionally, as shown in Figure 6 As shown, the second limiting groove 120 is formed as a second arc-shaped groove, and the extension direction of the second arc-shaped groove is designed based on the motion envelope of the connecting pin 530 when the connecting arm 200 rotates. Here, it can be understood that the extension direction of the second limiting groove 120 is formed as an arc shape.

[0107] At the same time, by limiting the swing of the connecting pin 530 through the second limiting groove 120, further limiting the swing of the pin shaft 312 can be achieved, and the position stability of the pin shaft 312 is improved, so as to facilitate the use of the pin shaft 312 to limit the displacement of the connecting arm 200 relative to the mounting base 100, to achieve the purpose of limiting the shaking of the door relative to the vehicle body, and make the door can also be stably opened and closed.

[0108] That is, the second limiting groove 120 of the present application not only makes the pin shaft 312 can effectively move relative to the mounting base 100 when the connecting arm 200 rotates relative to the mounting base 100, but also limits the swing of the pin shaft 312, so that the pin shaft 312 can move in a predetermined direction, and the position stability of the pin shaft 312 is guaranteed, so as to guarantee the position stability of the mounting base 100, and make the door can effectively and stably connect with the vehicle body by using the mounting base 100.

[0109] In some embodiments, the size of the second limiting groove 120 in the width direction thereof is equal to the outer diameter of the connecting pin 530, so as to limit the swing of the connecting pin 530 by using the second limiting groove 120, and make the connecting pin 530 can stably move along the extension direction of the second limiting groove 120, and the position stability of the connecting pin 530 is guaranteed.

[0110] Among them, the extension direction of the second limiting groove 120 is formed as an arc shape, and the width direction of the second limiting groove 120 can be understood as the direction perpendicular to the extension direction of the second limiting groove 120.

[0111] In some embodiments, as shown in Figure 1As shown, the connecting assembly 300 further comprises a swing arm 320, opposite ends of the swing arm 320 are rotatably connected with the mounting base 100 and the connecting arm 200 respectively. Here, it can be understood that one end of the swing arm 320 is rotatably connected with the mounting base 100, and the other end of the swing arm 320 is rotatably connected with the connecting arm 200, so as to avoid the swing arm 320 from hindering the rotation of the connecting arm 200 relative to the mounting base 100 to some extent, and the swing arm 320 can also support the connecting arm 200, so that the connecting arm 200 can rotate along the predetermined route, and the position stability of the connecting arm 200 during rotation can be improved, and the position stability of the vehicle door can be improved to some extent.

[0112] In some embodiments, as shown in Figure 1 As shown, the mounting base 100 is provided with a support 322, and one end of the swing arm 320 is rotatably connected with the mounting base 100 through the support 322, so as to realize the rotatable connection between the swing arm 320 and the mounting base 100, and reduce the difficulty of the rotatable connection between the swing arm 320 and the mounting base 100.

[0113] In some embodiments, as shown in Figure 1 As shown, the vehicle door hinge structure 1000 comprises a first shaft pin 321, the first shaft pin 321 is respectively arranged in the support 322 and one end of the swing arm 320, the support 322 is a swing arm support, the swing arm support and the first shaft pin 321 are rigidly connected, and the first shaft pin 321 and one end of the swing arm 320 are rotatably connected through a bushing, so as to realize the rotatable connection between the swing arm 320 and the support 322, and further realize the rotatable connection between the swing arm 320 and the mounting base 100.

[0114] Optionally, as shown in Figure 1 As shown, the vehicle door hinge structure 1000 comprises a second shaft pin 323, the second shaft pin 323 is respectively arranged in the connecting arm 200 and the other end of the swing arm 320, the second shaft pin 323 is rigidly connected with the connecting arm 200, and the other end of the swing arm 320 and the second shaft pin 323 are rotatably connected through a bushing, so as to realize the rotatable connection between the swing arm 320 and the connecting arm 200, and further realize the rotatable connection between the connecting arm 200 and the mounting base 100.

[0115] Among them, by rigidly connecting the swing arm support and the first shaft pin 321 and rigidly connecting the second shaft pin 323 with the connecting arm 200, the position stability of the first shaft pin 321 and the second shaft pin 323 can be improved, and the working performance of the first shaft pin 321 and the second shaft pin 323 can be ensured to some extent.

[0116] At the same time, by rotatably connecting the opposite ends of the swing arm 320 with the first shaft pin 321 and the second shaft pin 323 through the bushing, the wear between the swing arm 320 and the first shaft pin 321 and the second shaft pin 323 can be reduced, and the service life of the first shaft pin 321, the second shaft pin 323 and the swing arm 320 can be prolonged.

[0117] In some embodiments, the swing arm 320 is rotatably connected to the mounting base 100 to form a first rotation axis, and the swing arm 320 is rotatably connected to the connecting arm 200 to form a second rotation axis, and the first rotation axis and the second rotation axis intersect. The intersection of the first rotation axis and the second rotation axis can be understood as Figure 1 The point O shown in the figure is the rotation center point of the vehicle door hinge structure 1000, so that the connecting arm 200 can effectively rotate along a predetermined route, thereby allowing the vehicle door to be formed into a scissor door.

[0118] It should be noted that when driven by external force, the connecting arm 200 drives the car door to perform spherical curve motion, the motion trajectory of the swing arm 320 when it is rotationally connected to the mounting seat 100 forms a first rotation axis, and the motion trajectory of the swing arm 320 when it is rotationally connected to the connecting arm 200 forms a second rotation axis.

[0119] In some embodiments, combined Figure 1 and Figure 2 As shown, connecting arm 200 is provided with an electric support rod connection point 210 and a balance rod connection point 220. Electric support rod connection point 210 is connected to an electric support rod (not shown), and balance rod connection point 220 is connected to a balance rod (not shown). When the electric support rod at electric support rod connection point 210 and the balance rod at balance rod connection point 220 provide driving force, connecting arm 200 will move in space, allowing the vehicle door to move relative to the vehicle body, thereby realizing the door's opening and closing.

[0120] Among them, the electric strut mainly provides power for opening or closing the car door, which can enable the car door to be opened without manpower, and can make the car door hinge structure 1000 hover at any position. The balance bar can provide thrust for the movement of the door hinge structure 1000, bear the gravity of the car door, and assist the electric strut to realize the opening and closing of the car door, thereby enhancing the stability when using the car door.

[0121] In some embodiments, the balancing rod is used to balance the force between the connecting arm 200 and the vehicle door, so that the two are in a balanced and stable state.

[0122] In summary, when the connecting arm 200 starts the spatial motion under the driving force provided by the electric support rod at the electric support rod connecting point 210 and the balance rod at the balance rod connecting point 220, the swing arm 320 rotates relative to the mounting seat 100 around the first rotation axis, and simultaneously rotates relative to the connecting arm 200 around the second rotation axis, at this time, the connecting arm 200 drives the spherical bushing 314 to rotate relative to the pin shaft 312, and further drives the first connecting rod 510 to rotate relative to the connecting pin 530, and in the process of motion, the connecting pin 530 and the second connecting rod 520 rotate relative to the stud 521, at this time, the mechanism is a four-rotation-pair and one-spherical-pair motion mechanism, the first rotation axis, the second rotation axis, the connecting pin 530 and the stud 521 are rotation pairs, and the spherical center of the ball head 311 is a spherical pair, thereby forming the door hinge structure 1000.

[0123] It should be noted that when the connecting arm 200 drives the components in the door hinge structure 1000 to move, although all the components move along spherical curves around the rotation center point O, the movement pace of each component is not consistent, and therefore the door hinge structure 1000 can control the posture of the door at each opening angle by adjusting the parameters of the first rotation axis, the second rotation axis and the spherical center of the ball head 311.
