DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the description of the invention, it should be understood that the invention uses the terms "first", "second", etc. to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0030] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the left and right directions mentioned below. Figure 1 The projection direction is consistent with the front and back directions mentioned below. Figure 1 The left and right directions are consistent.

[0031] like Figures 1 to 3 As shown, this embodiment provides a vehicle door connecting hinge, including a first base 1 for installation on a vehicle body, a second base 2 for installation on a vehicle door, a sliding member 3 slidably mounted on the first base 1, a rotating member 4, and a universal joint 5. The first base 1 is used to be fixed on the vehicle body or the body, and the second base 2 is fixed on the vehicle door. The second base 2 is connected to the sliding member 3 through the universal joint 5, so that the second base 2 drives the vehicle door to rotate a certain angle along the design direction, and the movement trajectory of the vehicle door connected to the second base 2 is a spatial curve (extending outward and upward at the same time). The rotating member 4 has a first rotating shaft 401 rotatably mounted on the first base 1 and a second rotating shaft 402 rotatably mounted on the second base 2. The first base 1 is connected to the second base 2 through the rotating member 4. When the rotating member 4 rotates up and down around the first base 1, it can drive the second base 2 to flip, so that the rotating member drives the second base 2 to rotate around the axis of the first rotating shaft, and then the second base 2 drives the door to flip around the car body. The second base 2 is connected to the sliding member 3 through the universal joint 5. The sliding member 3 can only slide forward and backward, so that the second base has a certain movement trajectory. Therefore, during the flipping process of the door, the sliding member 3 can slide horizontally forward and backward along the movement direction of the car under the push of the universal joint 5 to prevent the door from getting stuck. During the flipping process of the door, the door moves outward (left or right) while rotating upward.

[0032] like Figure 3 and Figure 7 As shown, specifically, in one embodiment, the axis of the first rotating shaft 401 and the axis of the second rotating shaft 402 are at a predetermined angle, the first base 1 is installed at the front end of the vehicle body, and the second base 2 is installed at the front end of the door. The axis of the first rotating shaft 401 and the axis of the second rotating shaft 402 are not parallel, and the distance between the axis of the first rotating shaft 401 and the axis of the second rotating shaft 402 gradually increases from front to back. When the door can be opened outward around the vehicle body while rotating upward, as the door rotates, the outward opening range of the door is smaller than the upward movement, and the outward opening angle of the door is smaller when the door is fully opened upward.

[0033] Specifically, in one embodiment, the predetermined angle is 20°-45°. Preferably, in this embodiment, the predetermined angle is 30°, which ensures that the door opens outward at the minimum angle while ensuring the door opens smoothly, avoiding the door from opening upwards stuck due to the door opening outward at too small an angle.

[0034] Specifically, in one embodiment, the length of the first rotating shaft 401 is smaller than the length of the second rotating shaft 402, and the length of the first rotating shaft 401 is two-thirds to three-quarters of the length of the second rotating shaft 402, so that the speed at which the door opens upward is greater than the speed at which the door opens outward, and when the door is fully opened outward, the outward opening angle is smaller, thereby reducing the damage to pedestrians on the road or the door itself caused by the opening of the door.

[0035] The universal joint is a spherical surface pair structure, which includes a first connecting shaft fixedly connected to the sliding member, a rotating ball fixed on the first connecting shaft, and a second connecting shaft installed on the second base; the second connecting shaft is provided with a spherical groove, and the rotating ball is rotatably installed in the spherical groove to form a spherical surface pair structure. The second connecting shaft 503 has a spherical groove, and the maximum width of the groove of the spherical groove is smaller than the diameter of the spherical groove. The universal joint 5 has a rotating ball 502 for rotatably installing in the spherical groove, and the second connecting shaft 503 can rotate a certain angle along the design direction. The design direction is the movement direction of the rotating ball when the car door is designed to be opened.

[0036] like Figure 3 , Figure 4 and Figure 7 As shown, specifically, in one embodiment, the rotating member 4 also has a rotating seat 403. The rotating seat 403 has a first axial hole; the first rotating shaft 401 is installed in the first axial hole. The first base 1 is provided with a third positioning member 11 and a fourth positioning member 12; the third positioning member 11 has a fifth axial hole 13, and the fourth positioning member 12 has a sixth axial hole 14; the axis of the sixth axial hole 14 and the axis of the fifth axial hole 13 are both located on the first predetermined straight line. The first rotating shaft 401 is provided with a first limiting ring 404 and a second limiting ring 405, and the first limiting ring 404 and the second limiting ring 405 are arranged at intervals along the axial direction of the first rotating shaft 401; the first limiting ring 404 and the second limiting ring 405 are separated at both ends of the axial direction of the first rotating shaft 401 and are both fixed to the outer circumferential side of the first rotating shaft 401. The first rotating shaft 401 passes through the fifth shaft hole 13, the first shaft hole, and the sixth shaft hole 14 in sequence; the rotating seat 403 is clamped between the third positioning member 11 and the fourth positioning member 12, the third positioning member 11 is clamped between the rotating seat 403 and the first limiting ring 404, the fourth positioning member 12 is clamped between the rotating seat 403 and the second limiting ring 405, the first limiting ring 404 and the second limiting ring 405 prevent the first rotating shaft 401 from falling off, and the third positioning member 11 and the fourth positioning member 12 limit the rotating seat 403 from sliding along the first predetermined straight line.

[0037] Specifically, in one embodiment, the first base 1 is further provided with a fifth positioning member 15 and a sixth positioning member 16; the fifth positioning member 15 has a first slide groove 17, and the sixth positioning member 16 has a second slide groove 18; the first slide groove 17 and the second slide groove 18 respectively penetrate the fifth positioning member 15 and the sixth positioning member 16 along the second predetermined straight line. The sliding member 3 is provided with a boss 19 having a first connecting hole 20, the boss 19 is cylindrical, and a thread is provided in the first connecting hole 20. The first connecting shaft 501 of the universal joint is fixed in the first connecting hole 20, and the first connecting shaft 501 is provided with an external thread threadedly connected with the first connecting hole 20. One end of the sliding member 3 is slidably installed in the first slide groove 17 of the fifth positioning member 15, and the other end of the sliding member 3 is slidably installed in the second slide groove 18 of the sixth positioning member 16, the boss 19 is located between the fifth positioning member 15 and the sixth positioning member 16, and the fifth positioning member 15 and the sixth positioning member 16 enable the boss 19 to slide within a certain range.

[0038] Specifically, in one embodiment, the second predetermined straight line is horizontally arranged, and the angle between the first predetermined straight line and the second predetermined straight line is 15°, so that the door can be opened more smoothly.

[0039] The third positioning member 11, the fourth positioning member 12, the fifth positioning member 15 and the fifth positioning member 15 are all fixed on a predetermined plane of the first base 1, and the angle between the axis of the first connecting hole 20 and the predetermined plane is 45 degrees, so that the sliding member 3 slides more smoothly.

[0040] like Figure 3 , Figure 5 and Figure 7As shown, specifically, in one embodiment, the rotating seat 403 also has a second axial hole; the second base 2 is provided with a first positioning member 7 and a second positioning member 8, and the first positioning member 7 and the second positioning member 8 are both cylindrical. The first positioning member 7 has a third axial hole 9, and the second positioning member 8 has a fourth axial hole 10; the axis of the third axial hole 9 coincides with the axis of the third axial hole 9. The second rotating shaft 402 is provided with a third limiting ring 406 and a fourth limiting ring 407, and the third limiting ring 406 and the fourth limiting ring 407 are arranged at intervals along the axial direction of the second rotating shaft 402; the third limiting ring 406 and the fourth limiting ring 407 are separated at both ends of the second rotating shaft 402 and are fixed to the outer circumferential side of the second rotating shaft 402. The second rotating shaft 402 passes through the third shaft hole 9, the second shaft hole, and the fourth shaft hole 10 in sequence; the rotating seat 403 is clamped between the first positioning member 7 and the second positioning member 8, the first positioning member 7 is clamped between the rotating seat 403 and the third limiting ring 406, and the second positioning member 8 is clamped between the rotating seat 403 and the fourth limiting ring 407. The third limiting ring 406 and the fourth limiting ring 407 prevent the second rotating shaft 402 from being separated from the first positioning member 7, the second positioning member 8, and the rotating seat 403. The first positioning member 7 and the second positioning member 8 limit the rotating seat 403 to move along the axis of the third shaft hole 9 or the axis direction of the third shaft hole 9, so that the rotating seat 403 and the second rotating shaft 402 can only rotate.

[0041] Specifically, in one embodiment, a first shaft sleeve 408 is installed in the first shaft hole, and the first rotating shaft 401 is installed in the first shaft hole through the first shaft sleeve 408. A second shaft sleeve 409 is installed in the second shaft hole, and the second rotating shaft 402 is installed in the second shaft hole through the second shaft sleeve 409. This makes the rotation of the first rotating shaft 401 and the second rotating shaft 402 smoother.

[0042] Specifically, in one embodiment, the rotating seat 403 is provided with a first limit block 21, and the first base 1 is provided with a second limit block 22. The second limit block 22 is located between the third positioning member 11 and the fourth positioning member 12 and connected to the third positioning member 11, thereby increasing the strength of the second limit block 22. The second limit block 22 is located on the rotation path of the first limit block 21. When the door is opened, the rotating seat 403 rotates upward around the first rotation axis until the door is opened to the maximum setting of the maximum opening, and the first limit block 21 abuts against the second limit block 22 to achieve the positioning of the door opening and ensure that it will not be opened too far.

[0043] Figure 1 , Figure 3 as well as Figure 4As shown, specifically, in one embodiment, the fifth positioning member 15 includes a positioning block 1501 fixed on the first base 1 and a pressure cover 1502 installed on the positioning block 1501; threaded holes are provided on the pressure cover 1502 and the positioning block 1501, and the pressure cover 1502 is detachably connected to the positioning block 1501 by bolts to facilitate the installation of the sliding member 3, and the pressure cover 1502 and the positioning block 1501 together enclose a first slide groove 17.

[0044] Figure 1 , Figure 3 as well as Figure 6 As shown, specifically, in one embodiment, the first slide groove 17 and the second slide groove 18 are both rectangular holes, and the sliding member 3 is a rectangular bar. There is a gap between the sliding member 3 and the first base 1 to reduce friction. The first slide groove 17 and the second slide groove 18 can also be a V-shaped groove, an elliptical groove, etc.

[0045] Specifically, in one embodiment, adjacent outer side surfaces of the sliding member 3 are smoothly connected by providing rounded corners, and the inner wall of the rectangular hole is provided with an arc chamfer, so that the sliding member 3 slides more smoothly. The boss 19 is located at one of the rounded corners of the sliding member 3, and the axis of the first connecting hole 20 on the boss 19 coincides with one of the diagonals of the sliding member 3.

The second connection shaft 503 is installed in the second connection hole 201 and is threadedly connected to the second base 2. The notch of the spherical groove is located on one of the end faces of the second connection shaft 503.

[0047] Specifically, in one embodiment, the angle between the axis of the second connecting hole 201 and the axis of the third axial hole 9 is 45°, so that the rotation of the pressure cover 1502 is smoother, thereby making the rotation of the vehicle door along the spatial curved path smoother.

[0048] Specifically, in one embodiment, a through hole 504 connected to the spherical groove is provided on the other end surface of the second connecting shaft 503, and the diameter of the through hole 504 is smaller than the diameter of the spherical groove. The through hole 504 can prevent the gland 1502 from getting stuck, and lubricating oil can also be added through the through hole 504.

[0049] Figure 1 and Figure 2 As shown, specifically, in one embodiment, the second base 2 is mounted on the vehicle door by bolts, and the first base 1 is mounted on the vehicle body by bolts.

[0050] The working principle of the present invention is as follows: the first base is mounted on the vehicle body, the second base is mounted on the vehicle door, and in the process of opening the vehicle door, the rotating base rotates upward around the first rotating axis while the second rotating axis moves outward, and the vehicle door rotates as the second rotating axis moves, so that the vehicle door opens outward while moving upward. In the process of the vehicle door opening outward while moving upward, the second base flips around the first connecting axis on the sliding member through the second connecting axis on a predetermined spatial curve, and the sliding member slides back and forth. When the second rotating axis flips upward around the first rotating axis and abuts against the upper end of the first base, the vehicle door is fully opened, and when the second rotating axis flips downward around the first rotating axis and abuts against the lower end of the first base, the vehicle door is fully closed.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
