[0041] The embodiments of the present application are described below in detail with reference to the accompanying drawings. The embodiments of the present application described below in detail are exemplary, and the embodiments of the present application are described below in detail.

[0042] The embodiments of the present application are described below in detail with reference to the accompanying drawings. The embodiments of the present application described below in detail are exemplary, and the embodiments of the present application are described below in detail. Figures 1-7 The hinge assembly 100 according to the embodiments of the present application is described below with reference to the accompanying drawings, and the hinge assembly 100 can be applied to the vehicle door which can be applied to the vehicle.

[0043] The hinge assembly 100 according to the embodiments of the present application is described below with reference to the accompanying drawings, and the hinge assembly 100 can be applied to the vehicle door which can be applied to the vehicle. Figures 1-7 As shown, the hinge assembly 100 according to the present application can mainly include: a mounting seat 10, a first fixed shaft swing arm member 20, a second fixed shaft swing arm member 30, a sliding block member 40, a connecting rod member 60 and a door connecting swing arm 50, wherein the mounting seat 10 can be used for connecting the hinge assembly 100 with the side wall of the vehicle, which can facilitate the connection of the hinge assembly 100 with the vehicle and improve the assembly convenience of the hinge assembly 100.

[0044] Further, the first fixed shaft swing arm member 20 is rotatably arranged on the mounting seat 10. Specifically, one end of the first fixed shaft swing arm member 20 is rotatably arranged on the mounting seat 10, which not only connects the first fixed shaft swing arm member 20 with the mounting seat 10, ensures that the position of one end of the first fixed shaft swing arm member 20 relative to the plane of the mounting seat 10 does not change, and stably arranges the first fixed shaft swing arm member 20 in the hinge assembly 100, but also through the rotation of one end of the first fixed shaft swing arm member 20 relative to the mounting seat 10, the other end of the first fixed shaft swing arm member 20 can be away from and close to the mounting seat 10, so as to open and close the door through the hinge assembly 100.

[0045] Further, the second fixed shaft swing arm member 30 is rotatably arranged on the mounting seat 10. Specifically, one end of the second fixed shaft swing arm member 30 is rotatably arranged on the mounting seat 10, which not only connects the second fixed shaft swing arm member 30 with the mounting seat 10, ensures that the position of one end of the second fixed shaft swing arm member 30 relative to the plane of the mounting seat 10 does not change, and stably arranges the second fixed shaft swing arm member 30 in the hinge assembly 100, but also through the rotation of one end of the second fixed shaft swing arm member 30 relative to the mounting seat 10, the other end of the second fixed shaft swing arm member 30 can be away from and close to the mounting seat 10, so as to open and close the door through the hinge assembly 100.

[0046] Further, the slider 40 is movably connected with the first fixed-axle swing arm 20. Specifically, the slider 40 is connected with the first fixed-axle swing arm 20 and can move on the first fixed-axle swing arm 20, which not only can stably arrange the slider 40 in the hinge assembly 100, but also can limit the moving direction of the slider 40 in the hinge assembly 100 through the first fixed-axle swing arm 20, so that the slider 40 slides along the limited path, thereby limiting the moving path of the door connected with the hinge assembly 100 to ensure that the door moves along the set path.

[0047] In addition, the slider 40 is rotatably connected with the second fixed-axle swing arm 30, so that one end of the second fixed-axle swing arm 30 can freely rotate relative to the slider 40. During the movement of the slider 40 along the first fixed-axle swing arm 20, one end of the second fixed-axle swing arm 30 can simultaneously move along the axis of the first fixed-axle swing arm 20. At the same time, the slider 40, the first fixed-axle swing arm 20 and the second fixed-axle swing arm 30 can simultaneously move away from and close to the mounting base 10, so that the movement of the hinge assembly 100 can drive the door to open and close. When the slider 40 moves towards the direction of closing to the mounting base 10, the door is closed, and when the slider 40 moves towards the direction of moving away from the mounting base 10, the door is opened, so that the door can be opened and closed on the vehicle in the form of side opening.

[0048] Further, the door connecting swing arm 50 is rotatably connected with the slider 40, and the door connecting swing arm 50 is adapted to be connected with the door. Specifically, the door connecting swing arm 50 is connected with the slider 40, so that the door connecting swing arm 50 and the slider 40 can move synchronously. Thus, when the slider 40 moves towards the mounting base 10 and moves away from the mounting base 10, the door connecting swing arm 50 can move towards the mounting base 10 and move away from the mounting base 10 synchronously. The door connecting swing arm 50 is adapted to be connected with the door, so that the door and the door connecting swing arm 50 can move synchronously. When the door connecting swing arm 50 moves towards the mounting base 10, the door is driven to close, and when the door connecting swing arm 50 moves away from the mounting base 10, the door is driven to open, so that the door can be opened and closed on the vehicle in the form of side opening.

[0049] Further, the door connecting swing arm 50 is rotatably connected with the slider 40, so that the door connecting swing arm 50 can freely rotate relative to the slider 40. When the door connecting swing arm 50 and the slider 40 move synchronously, the door connecting swing arm 50 can freely rotate on the slider 40, so that the door has the form of upward rotation when the door connecting swing arm 50 drives the door to open and close in the form of side opening.

[0050] Further, one end of the connecting rod 60 is rotatably connected with the door connecting swing arm 50, and the other end of the connecting rod 60 is rotatably connected with the first fixed shaft rotating arm member 20. Specifically, one end of the connecting rod 60 is connected with the door connecting swing arm 50, so that the force is transmitted between the connecting rod 60 and the door connecting swing arm 50, and the connecting rod 60 and the door connecting swing arm 50 can rotate relative to each other. The other end of the connecting rod 60 is connected with the first fixed shaft rotating arm member 20, which can stably arrange the connecting rod 60 on the first fixed shaft rotating arm member 20 and can move synchronously with the first fixed shaft rotating arm member 20 relative to the mounting base 10. In this way, when the connecting rod 60 rotates relative to the door connecting swing arm 50, the connecting rod 60 and the door connecting swing arm 50 can move synchronously, so that the door connecting swing arm 50 can smoothly rotate upward while driving the door to open sideways, thereby ensuring the smoothness of the operation of the door hinge. On the other hand, the position of one end of the connecting rod 60 relative to the first fixed shaft rotating arm member 20 is unchanged, and the other end of the connecting rod 60 can move synchronously with the door connecting swing arm 50. When the sliding block 40 slides along the first fixed shaft rotating arm member 20, since the length of the connecting rod 60 and the door connecting swing arm 50 is unchanged and cannot be bent, the end of the connecting rod 60 connected with the door connecting swing arm 50 rotates relative to the first fixed shaft rotating arm member 20, and the end of the door connecting swing arm 50 connected with the connecting rod 60 rotates relative to the sliding block 40. The door connecting swing arm 50 can drive the door to rotate relative to the sliding block 40, so that the door can rotate upward while opening sideways, thereby realizing the scissor state of the door.

[0051] Therefore, by arranging the sliding block 40 to be movable on the first fixed shaft rotating arm member 20, the door connecting swing arm 50 is connected with the connecting rod 60 at one end and with the door at the other end, and can rotate relative to the sliding block 40. Therefore, not only can the door be opened sideways and rotated upward, but also the smoothness of the movement of the hinge assembly 100 can be improved, thereby meeting the design requirements of the vehicle and improving the driving experience of the user.

[0052] In combination Figures 1-3 As shown in the drawings, the first fixed shaft rotating arm member 20 includes a first fixed shaft part 21 and a first rotating arm part 22, and the first fixed shaft part 21 is rotatably arranged on the mounting base 10. Specifically, the first fixed shaft rotating arm member 20 is composed of the first fixed shaft part 21 and the first rotating arm part 22, which can simplify the structure of the first fixed shaft rotating arm member 20, facilitate the production and assembly of the first fixed shaft rotating arm member 20, and rotatably arrange the first fixed shaft part 21 on the mounting base 10. Therefore, not only can the first fixed shaft rotating arm member 20 be fixed on the mounting base 10, but also the first fixed shaft rotating arm member 20 can rotate relative to the mounting base 10, so that the position of the first fixed shaft rotating arm member 20 on the mounting base 10 is unchanged, and the first fixed shaft rotating arm member 20 can freely rotate on the mounting base 10.

[0053] Further, the first rotating arm portion 22 is arranged on the first fixed shaft portion 21, so that the first fixed shaft portion 21 can provide a stable and reliable connecting position for the first rotating arm portion 22, and the force and movement can be directly transmitted between the first fixed shaft portion 21 and the first rotating arm portion 22, so that the transmission efficiency of the force and movement in the first fixed shaft rotating arm piece 20 can be improved, thereby improving the responsiveness of the hinge assembly 100 when the user pulls the door, and in the process of rotating the first fixed shaft portion 21 relative to the mounting seat 10, the first rotating arm portion 22 can rotate together with the first fixed shaft portion 21 about the rotating axis of the first fixed shaft portion 21 relative to the mounting seat 10.

[0054] Further, in the closed state of the door, the first rotating arm portion 22 extends towards the second fixed shaft rotating arm piece 30, so that the first rotating arm portion 22 can guide the sliding of the sliding block piece 40, and the sliding block piece 40 can be slidably arranged on the first rotating arm portion 22, so that the sliding of the sliding block piece 40 on the first rotating arm portion 22 can be smooth, and the movement of the sliding block piece 40 in the hinge assembly 100 can be smooth, thereby improving the operation stability of the hinge assembly 100.

[0055] In combination with Figure 2 and Figure 3 As shown in the drawings, the second fixed shaft rotating arm piece 30 includes a second fixed shaft portion 31 and a second rotating arm portion 32, the second fixed shaft portion 31 is rotatably arranged on the mounting seat 10, and the second rotating arm portion 32 is arranged on the second fixed shaft portion 31 and extends towards the first fixed shaft rotating arm piece 20, and the end of the second rotating arm portion 32 away from the second fixed shaft portion 31 is rotatably connected with the sliding block piece 40. Specifically, the second fixed shaft rotating arm piece 30 is composed of the second fixed shaft portion 31 and the second rotating arm portion 32, so that the structure of the second fixed shaft rotating arm piece 30 can be simplified, and the production and assembly of the second fixed shaft rotating arm piece 30 can be facilitated, the second fixed shaft portion 31 is rotatably arranged on the mounting seat 10, so that the second fixed shaft rotating arm piece 30 can be fixed on the mounting seat 10, and the second fixed shaft rotating arm piece 30 can rotate relative to the mounting seat 10, so that the position of the second fixed shaft rotating arm piece 30 on the mounting seat 10 can be kept unchanged, and the second fixed shaft rotating arm piece 30 can rotate freely on the mounting seat 10.

[0056] Further, the second rotating arm part 32 is arranged on the second fixed shaft part 31, so that the second fixed shaft part 31 can provide a stable and reliable connecting position for the second rotating arm part 32, and the force and movement can be directly transmitted between the second fixed shaft part 31 and the second rotating arm part 32, the transmission efficiency of the force and movement in the second fixed shaft rotating arm piece 30 can be improved, so that the response and timeliness of the hinge assembly 100 when the user pulls open the door can be improved, and in the process of rotating the second fixed shaft part 31 relative to the mounting seat 10, the second rotating arm part 32 can rotate together with the second fixed shaft part 31 around the rotating axis of the second fixed shaft part 31 relative to the mounting seat 10.

[0057] Further, in the closed state of the door, the second rotating arm part 32 extends towards the second fixed shaft rotating arm piece 30, so that the end of the second rotating arm part 32 away from the second fixed shaft part 31 is rotatably connected with the sliding block piece 40, the assembly convenience of the hinge assembly 100 can be improved, and the reliability of the transmission of force and movement between the second rotating arm part 32 and the sliding block piece 40 can be ensured.

[0058] When the sliding block piece 40 has a tendency to slide close to the second fixed shaft rotating arm piece 30, the sliding block piece 40 can directly transmit the force to the second rotating arm part 32, and the second rotating arm part 32 has a tendency to move close to the second fixed shaft part 31, so that when the sliding block piece 40 starts to slide to the position of the second fixed shaft rotating arm piece 30, the second rotating arm part 32 can drive the second fixed shaft part 31 to rotate together around the rotating axis of the second fixed shaft part 31 relative to the mounting seat 10, and the sliding block piece 40 can slide on the first rotating arm part 22 from the position away from the second fixed shaft rotating arm piece 30 to the position close to the second fixed shaft rotating arm piece 30, and rotate together with the second rotating arm part 32 around the rotating axis of the second fixed shaft part 31 relative to the mounting seat 10. In the embodiment of the present application, the door connecting swing arm 50 slides together with the sliding block piece 40 on the first rotating arm part 22 from the position away from the second fixed shaft rotating arm piece 30 to the position close to the second fixed shaft rotating arm piece 30, and rotates together around the rotating axis of the second fixed shaft part 31 relative to the mounting seat 10, which is the movement form of realizing the side opening of the vehicle door.

[0059] In combination Figure 3As shown, the first fixed shaft part 21 and the second fixed shaft part 31 are arranged in the first direction, and the first rotating arm part 22 and the second rotating arm part 32 are arranged in the second direction, wherein the first direction and the second direction are perpendicular to each other. Specifically, the first fixed shaft part 21 and the second fixed shaft part 31 are rotatably arranged on the mounting base 10 and arranged in the first direction, which can prevent the first rotating arm part 22 from interfering with the second fixed shaft part 31 during rotation, can prevent the second rotating arm part 32 from interfering with the first fixed shaft part 21 during rotation, and can further ensure the smoothness of the movement of the hinge assembly 100. The first rotating arm part 22 and the second rotating arm part 32 are arranged in the second direction, which not only facilitates the connection of the slider 40 with the first rotating arm part 22 and the second rotating arm part 32, but also prevents the first rotating arm part 22 and the second rotating arm part 32 from interfering with each other during the movement of the slider 40 along the first rotating arm part 22, and can further improve the smoothness of the movement of the hinge assembly 100.

[0060] In addition, the first direction and the second direction are perpendicular to each other, which can prevent the direction of the sliding of the slider 40 along the first rotating arm part 22 from being inclined to interfere with the axis of rotation of the first rotating arm part 22 relative to the mounting base 10 during the movement of the slider 40. During the production of the hinge assembly 100, as long as the first direction and the second direction are perpendicular to each other, the movement of the hinge assembly 100 in multiple directions can be achieved, which not only facilitates the coupling of the multiple direction movements of the slider 40, but also ensures the smoothness of the movement of the slider 40, and further reduces the precision requirements during the production and assembly of the hinge assembly 100, thereby reducing the production difficulty of the hinge assembly 100.

[0061] In combination Figure 1 As shown, the rotation axis of the first fixed shaft part 21 relative to the mounting base 10 is parallel to the plane on which the mounting base 10 is located, the rotation axis of the second fixed shaft part 31 relative to the mounting base 10 is parallel to the plane on which the mounting base 10 is located, and the rotation axis of the second fixed shaft part 31 relative to the mounting base 10 is parallel to the rotation axis of the first fixed shaft part 21 relative to the mounting base 10.

[0062] Specifically, the rotation axis of the first fixed shaft part 21 relative to the mounting base 10 is parallel to the plane on which the mounting base 10 is located, which not only prevents the first fixed shaft part 21 from colliding with the mounting base 10 during rotation, ensures the stable and smooth rotation of the first fixed shaft part 21 on the mounting base 10, but also allows the first fixed shaft part 21 to be as close to the mounting base 10 as possible, improves the compactness of the structure of the hinge assembly 100, and is conducive to reducing the structural size of the hinge assembly 100, making the movement of the hinge assembly 100 more stable and reliable.

[0063] Further, the rotation axis of the second fixed shaft part 31 relative to the mounting base 10 is parallel to the plane on which the mounting base 10 lies, so that not only can the second fixed shaft part 31 be prevented from colliding with the mounting base 10 during rotation, the rotation of the second fixed shaft part 31 on the mounting base 10 can be ensured to be stable and smooth, but also the second fixed shaft part 31 can be made as close to the mounting base 10 as possible, the structural compactness of the hinge assembly 100 can be improved, and the structure size of the hinge assembly 100 can be reduced, so that the movement of the hinge assembly 100 is more stable and reliable.

[0064] In addition, the rotation axis of the second fixed shaft part 31 relative to the mounting base 10 is parallel to the rotation axis of the first fixed shaft part 21 relative to the mounting base 10, so that the first rotating arm part 22 and the second rotating arm part 32 can be ensured to be parallel to each other, and the interference between the first rotating arm part 22 and the second rotating arm part 32 can be prevented to cause the sliding block 40 to run stuck, so that the movement smoothness of the hinge assembly 100 can be ensured.

[0065] In combination Figure 1 As shown, one end of the door connecting swing arm 50 is rotatably connected with the connecting rod 60, and the other end of the door connecting swing arm 50 away from the connecting rod 60 is adapted to be connected with the door, and the connection point of the door connecting swing arm 50 and the sliding block 40 is located between the two ends of the door connecting swing arm 50, so that the one end of the door connecting swing arm 50 connected with the connecting rod 60 and the one end of the door connecting swing arm 50 connected with the door can swing in different directions on the two sides of the first direction of the sliding block 40. When the one end of the door connecting swing arm 50 connected with the connecting rod 60 swings downward, the one end of the door connecting swing arm 50 connected with the door swings upward, and the door connecting swing arm 50 drives the door to open upward, and when the one end of the door connecting swing arm 50 connected with the connecting rod 60 swings upward, the one end of the door connecting swing arm 50 connected with the door swings downward, and the door connecting swing arm 50 drives the door to close downward.

[0066] In combination Figure 1 And Figure 5 As shown, the rotation axis of the connecting rod 60 relative to the first fixed shaft part 21 is a first rotation axis, the rotation axis of the first fixed shaft part 21 relative to the mounting base 10 is a second rotation axis, the first rotation axis and the second rotation axis intersect and form a first intersection point, the axis on which the sliding block 40 moves on the first rotating arm part 22 is a movement axis, and the first intersection point is located on the extension line of the movement axis.

[0067] Specifically, the first intersection point formed by the first rotation axis and the second rotation axis is located on the extension line of the movement axis, and during the sliding of the slider 40 along the first arm portion 22, it can be ensured that the first arm portion 22, the slider 40, the door connecting swing arm 50, and the connecting rod 60 are all rotated around the second rotation axis under the driving of the first fixed shaft portion 21, so that interference and wear between the first arm portion 22, the slider 40, the door connecting swing arm 50, the connecting rod 60, and the first fixed shaft portion 21 can be prevented, and further, the movement of the hinge assembly 100 can be made smooth and noise can be reduced. In this way, the door connecting swing arm 50 can be smoothly rotated around the second rotation axis, and the movement smoothness of the hinge assembly 100 can be improved.

[0068] In combination Figure 3 As shown, the rotation axis of the second arm portion 32 relative to the slider 40 is a third rotation axis, the rotation axis of the door connecting swing arm 50 relative to the slider 40 is a fourth rotation axis, the third rotation axis intersects the fourth rotation axis and forms a second intersection point, and the axis of the movement of the slider 40 on the first arm portion 22 is a movement axis. The second intersection point is located on the extension line of the movement axis.

[0069] Specifically, the second intersection point formed by the third rotation axis and the fourth rotation axis is located on the extension line of the movement axis, and during the sliding of the slider 40 along the first arm portion 22, it can be ensured that the end of the second arm portion 32 connected with the slider 40 and the door connecting swing arm 50 are all moved along the first arm portion 22 under the driving of the slider 40, so that interference between the second arm portion 32, the slider 40, and the door connecting swing arm 50 can be prevented, and further, noise can be reduced and the movement smoothness of the hinge assembly 100 can be improved. In this way, the slider 40 can be smoothly moved on the first arm portion 22, and the movement smoothness of the hinge assembly 100 can be improved.

[0070] In combination Figure 1 As shown, the mounting seat 10 is provided with a first shaft seat 11 and a second shaft seat 12, the first fixed shaft portion 21 is rotatably connected with the first shaft seat 11 to form a first rotation pair 110, the second fixed shaft portion 31 is rotatably connected with the second shaft seat 12 to form a second rotation pair 120, the slider 40 is rotatably connected with the second arm portion 32 to form a third rotation pair 130, the door connecting swing arm 50 is rotatably connected with the slider 40 to form a fourth rotation pair 140, the door connecting swing arm 50 is rotatably connected with the connecting rod 60 to form a fifth rotation pair 150, and the connecting rod 60 is rotatably connected with the first fixed shaft portion 21 to form a sixth rotation pair 160.

[0071] Specifically, the first shaft seat 11 is configured to fix the first fixed shaft part 21 to the mounting seat 10, and the first fixed shaft part 21 can rotate freely relative to the first shaft seat 11, so that the first fixed shaft rotating arm part 20 is rotatably connected to the mounting seat 10 to form a first rotating pair 110 of the hinge assembly 100. The second shaft seat 12 is configured to fix the second fixed shaft part 31 to the mounting seat 10, and the second fixed shaft part 31 can rotate freely relative to the second shaft seat 12, so that the second fixed shaft rotating arm part 30 is rotatably connected to the mounting seat 10 to form a second rotating pair 120 of the hinge assembly 100. The slider part 40 and the second rotating arm part 32 form a third rotating pair 130 of the hinge assembly 100, so that the slider part 40 and the second rotating arm part 32 are rotatably connected. The door connecting swing arm 50 and the slider part 40 form a fourth rotating pair 140 of the hinge assembly 100, so that the door connecting swing arm 50 and the slider part 40 are rotatably connected. The door connecting swing arm 50 and the connecting rod part 60 form a fifth rotating pair 150 of the hinge assembly 100, so that the door connecting swing arm and the connecting rod part 60 are rotatably connected. The connecting rod part 60 and the first fixed shaft part 21 form a sixth rotating pair 160 of the hinge assembly 100, so that the connecting rod part 60 and the first fixed shaft part 21 are rotatably connected. In this way, the hinge assembly 100 has multiple degrees of rotational freedom, so that the side opening and upward rotation of the door can be facilitated.

[0072] In combination Figure 7 As shown, the distance between the connecting end of the door connecting swing arm 50 corresponding to the connection between the door connecting swing arm 50 and the connecting rod part 60 and the slider part 40 is L1, and the length of the connecting rod part 60 is L2, and L1 and L2 satisfy the relationship L1=L2. Specifically, the distance between the connecting end of the door connecting swing arm 50 corresponding to the connection between the door connecting swing arm 50 and the connecting rod part 60 and the slider part 40 and the length of the connecting rod part 60 are equal, so that the forces of these two parts of the structure are equal. In this way, not only can the slider part 40 slide along the first rotating arm part 22 and the door connecting swing arm 50 rotate around the slider part 40 when the hinge assembly 100 is working, but also the amount of shaking of the door connecting swing arm 50 during movement can be minimized when the slider part 40 slides along the first rotating arm part 22. This can make the sliding of the slider part 40 along the first rotating arm part 22 more stable, and the relative rotation of the door connecting swing arm 50 and the connecting rod part 60 more stable, thereby improving the stability of the hinge assembly 100 and facilitating the user's operation experience of opening and closing the door.

[0073] In combination Figure 6As shown, a plane perpendicular to the rotation axis of the first fixed-axis rotating arm member 20 relative to the mounting base 10 and parallel to the rotation axis of the connecting rod member 60 relative to the first fixed-axis rotating arm member 20 is set as a first reference plane, an included angle α between the projections of the axis of the first rotating arm portion 22 and the axis of the second rotating arm portion 32 on the first reference plane is formed, and α satisfies the relationship: 0≤α≤pi / 18. Specifically, the included angle between the projections of the axis of the first rotating arm portion 22 and the axis of the second rotating arm portion 32 on the first reference plane is set to be between 0 and pi / 18. If the included angle between the projections of the axis of the first rotating arm portion 22 and the axis of the second rotating arm portion 32 on the first reference plane is less than 0, the three lines of the axis of the first fixed-axis rotating arm member 20 relative to the mounting base 10, the axis of the second fixed-axis rotating arm member 30 relative to the mounting base 10, and the axis of the second fixed-axis rotating arm member 30 relative to the sliding block member 40 are coplanar, which may result in a situation that the door and the vehicle body are locked and cannot be opened. If the included angle between the projections of the axis of the first rotating arm portion 22 and the axis of the second rotating arm portion 32 on the first reference plane is greater than pi / 18, the side opening angle of the door is too large, which not only cannot meet the design form when the door is opened, but also is prone to collide with people and objects around the door, thereby increasing the safety hazard of the door. Therefore, the included angle between the projections of the axis of the first rotating arm portion 22 and the axis of the second rotating arm portion 32 on the first reference plane is between 0 and pi / 18, which not only can ensure that the door is normally opened and that people can smoothly enter and exit the vehicle cabin after the door is opened, but also can ensure that the design form is met after the door is opened, thereby ensuring the unfolding effect of the scissor door.

[0074] In combination Figure 5 As shown, an included angle β between the connecting rod member 60 and the door connecting swing arm 50 is formed, and β satisfies the relationship: pi / 4≤β≤pi / 2. Specifically, the included angle between the connecting rod member 60 and the door connecting swing arm 50 is set to be between pi / 4 and pi / 2. The size of the included angle between the connecting rod member 60 and the door connecting swing arm 50 is the size of the upper rotation angle of the end of the door connecting swing arm 50 away from the connecting rod member 60. The minimum included angle between the connecting rod member 60 and the door connecting swing arm 50 is not more than pi / 4, at which time the distance of the sliding block member 40 on the first fixed-axis rotating arm member 20 away from the second fixed-axis portion 31 is the farthest, which not only can ensure that the vehicle door is reliably closed, but also can prevent dead angles of the rotation of the connecting rod member 60 relative to the first fixed-axis rotating arm member 20 and the rotation of the door connecting swing arm 50 relative to the sliding block member 40, thereby ensuring the smoothness of the movement of the hinge assembly 100. The maximum included angle between the connecting rod member 60 and the door connecting swing arm 50 is not more than pi / 2, which can prevent the upper rotation angle of the door connecting swing arm 50 from being too large and the upper rotation speed from being too fast, thereby preventing the vehicle door from easily hitting people when the vehicle door is opened and further ensuring the safety of the user opening and closing the vehicle door.

[0075] In combination Figure 4As shown, the door connecting swing arm 50 has a closed position and an open position, and the door connecting swing arm 50 moves between the closed position and the open position. Specifically, the door connecting swing arm 50 is arranged to have the closed position and the open position, when the door connecting swing arm 50 is in the closed position, the sliding block 40 is in a position away from the second fixed swing arm 30 on the first fixed swing arm 20, when the door connecting swing arm 50 is in the open position, the sliding block 40 is in a position close to the second fixed swing arm 30 on the second fixed swing arm 30, and when the sliding block 40 slides between the position away from the second fixed swing arm 30 on the first fixed swing arm 20 and the position close to the second fixed swing arm 30 on the second fixed swing arm 30, the door connecting swing arm 50 can be moved between the closed position and the open position, so that the door connecting swing arm 50 can be in the closed position and the open position by sliding the sliding block 40 on the first fixed swing arm 20.

[0076] According to the embodiment of the present application, the projection of the axis on the first reference surface when the door connecting swing arm 50 is in the closed position and the projection of the axis on the first reference surface when the door connecting swing arm 50 is in the open position have an included angle γ, and γ satisfies the relationship: 0 < γ ≤ pi / 4. Specifically, the included angle between the projection of the axis on the first reference surface when the door connecting swing arm 50 is in the closed position and the projection of the axis on the first reference surface when the door connecting swing arm 50 is in the open position is the side opening angle of the door connecting swing arm 50, if the side opening angle of the door connecting swing arm 50 is less than 0, the door is locked with the vehicle body and cannot be separated, which will result in the door being unable to open, if the side opening angle of the door connecting swing arm 50 is greater than pi / 4, the side opening angle of the door is too large, and the steep shape of the door after opening is not obvious, which cannot guarantee the display effect of the door in the form of a pair of scissors, therefore, the side opening angle of the door connecting swing arm 50 is arranged to be between 0 and pi / 4, which not only guarantees the normal opening and closing of the door, but also guarantees that the side opening angle of the door is appropriate, and the design effect of the door after opening can be guaranteed.

[0077] According to the embodiment of the present application, the plane parallel to the rotation axis of the first fixed-axle rotating arm 20 relative to the mounting seat 10 and perpendicular to the rotation axis of the connecting rod 60 relative to the first fixed-axle rotating arm 20 is the second reference plane, the projection of the axis on the second reference plane when the door connecting swing arm 50 is in the closed position and the projection of the axis on the second reference plane when the door connecting swing arm 50 is in the open position have an included angle δ, and δ satisfies the relationship: 0 < δ ≤ 5pi / 18. Specifically, the included angle between the projection of the axis on the second reference plane when the door connecting swing arm 50 is in the closed position and the projection of the axis on the second reference plane when the door connecting swing arm 50 is in the open position is the upper rotation angle of the door connecting swing arm 50. If the upper rotation angle of the door connecting swing arm 50 is less than 0, the door connecting swing arm 50 cannot assume the upper rotation posture, the door is only in the side opening mode, and the design of the scissor door cannot be realized. If the upper rotation angle of the door connecting swing arm 50 is greater than 5pi / 18, the upper rotation angle of the door connecting swing arm 50 is too large, which not only affects the opening mode of the door, but also makes the door take too long to open, affecting the normal use of the vehicle. Therefore, the upper rotation angle of the door connecting swing arm 50 is designed to be between 0 and 5pi / 18, which not only realizes the upper rotation of the door after opening, but also ensures the normal operation of the door.

[0078] In combination Figure 1 and Figure 2 As shown in FIG. 5, the door connecting swing arm 50 is provided with at least one connecting piece 51, and the connecting piece 51 is used to connect the power spring. Specifically, the connecting piece 51 is arranged on the door connecting swing arm 50, which can facilitate the connection of the power spring on the door connecting swing arm 50. The expansion and contraction of the power spring can directly transmit force to the door connecting swing arm 50, so as to increase the driving force of the door connecting swing arm 50 when the door connecting swing arm 50 moves between the closed position and the open position, thereby accelerating the movement speed of the door connecting swing arm 50 while saving manpower, making it easier and more convenient to open the door of the vehicle. In addition, the number of connecting pieces 51 is at least one, so that different numbers of connecting pieces 51 can be installed on the door connecting swing arm 50 according to the different weights of the door of the vehicle, so as to connect different numbers of power springs, thereby adjusting the driving force of the power spring applied to the door connecting swing arm 50, so that the user can easily and labor-savingly open the door of different weights, thereby improving the operation experience of the user. In the embodiment of the present application, the power spring includes but is not limited to an electric spring, a pneumatic spring, and a balance spring.

[0079] According to the embodiment of the present application, the door of the vehicle comprises a hinge assembly 100 and a door body connected with the door connecting swing arm 50. Specifically, the hinge assembly 100 of the present application can be applied to the door of the vehicle, in which the door body can be used to close the driver cabin of the vehicle to ensure the safety of the person during the driving of the vehicle, and the door body can show the state of the door of the vehicle when it is opened and closed. The door body is connected with the door connecting swing arm 50, which can ensure the reliable transmission of force and movement between the door body and the door connecting swing arm 50.

[0080] When the door of the vehicle is opened, the person applies a pulling force to the door body with his hand, which makes the door body have a tendency to separate from the door lock. The pulling force can be directly transmitted to the door connecting swing arm 50 through the door body. The power spring applies an elastic force to the connecting piece 51 on the door connecting swing arm 50 through the extension and retraction action. The connecting piece 51 can directly transmit the elastic force of the power spring to the door connecting swing arm 50. The door connecting swing arm 50 transmits the pulling force and the elastic force received to the sliding block piece 40. When the sum of the external forces received by the sliding block piece 40 reaches the preset value of the door opening, the sliding block piece 40 slides along the axis of the first swing arm part 22 from the position away from the second fixed shaft swing arm piece 30 to the position close to the second fixed shaft swing arm piece 30 under the action of the external force. While the sliding block piece 40 moves, it can transmit the force to the second fixed shaft swing arm piece 30, so that the end of the second swing arm part 32 connected with the sliding block piece 40 rotates around the axis of the second fixed shaft part 31 relative to the mounting base 10. At the same time, the sliding block piece 40 rotates around the axis of the second fixed shaft part 31 relative to the mounting base 10, which drives the end of the first swing arm part 22 close to the sliding block piece 40 to rotate around the axis of the first fixed shaft part 21 relative to the mounting base 10. At this time, the axis of the first fixed shaft swing arm piece 20 relative to the mounting base 10, the axis of the second fixed shaft swing arm piece 30 relative to the mounting base 10, and the axis of the second fixed shaft swing arm piece 30 relative to the sliding block piece 40 are parallel to each other and not in the same plane. The door connecting swing arm 50 slides along the first fixed shaft swing arm piece 20 and rotates around the axis of the second fixed shaft swing arm piece 30 relative to the mounting base 10 along with the sliding block piece 40, so as to make the door body perform a side opening movement. In the embodiment of the present application, the preset value of the door opening is the force at the moment when the door connecting swing arm 50 is driven to move from the closed position to the open position.

[0081] In the embodiment of the present application, the hinge assembly 100 can be shared with the door body side wall and the door inner panel of the side opening door, so that the scissor door can use the arrangement state of the door lock of the side opening door on the door body, thereby saving the cost of opening the door body mold.

[0082] According to the embodiment of the present application, the alpha size and the beta size are not in linear relationship, and the larger the included angle between the connecting rod 60 and the door connecting swing arm 50 is designed, the faster the change rate of the rotation angle of the door connecting swing arm 50 is, and the slower the change rate of the angle of the included angle formed by the projections of the first swing arm part 22 axis and the second swing arm part 32 axis on the first reference plane is. When the door connecting swing arm 50 moves from the closed position to the open position, the change rate of the angle of the included angle formed by the projections of the first swing arm part 22 axis and the second swing arm part 32 axis on the first reference plane is fast at first and then slow during the sliding process of the slider 40 along the axis of the first swing arm part 22 from the position away from the second fixed swing arm part 30 to the position close to the second fixed swing arm part 30, which can make the door body quickly disconnect from the door lock under the driving of the door connecting swing arm 50, ensure that the door body can be smoothly opened, and the change rate of the included angle between the connecting rod 60 and the door connecting swing arm 50 is slow at first and then fast, which can ensure that the door body quickly rotates after the door body is completely disconnected from the door lock, and ensure that the posture of the door body after rotating is steep, so as to ensure that the door of the vehicle is opened in a scissors type.

[0083] In the embodiment of the present application, the crank slider mechanism composed of the connecting rod 60, the door connecting swing arm 50 and the slider 40 is the upper rotation plane mechanism of the hinge assembly 100, the swing guide rod mechanism composed of the first fixed swing arm part 20, the slider 40 and the second fixed swing arm part 30 is the side opening plane mechanism of the hinge assembly 100, and the upper rotation plane mechanism and the side opening plane structure are connected in parallel through the slider 40, so that the door body presents a parabolic motion trajectory when the door connecting swing arm 50 moves from the closed position to the open position. Such arrangement can not only improve the compactness of the hinge assembly 100, but also make the machining precision of the hinge assembly 100 easy to control, facilitate the implementation and assembly of the hinge assembly 100, and fix the movement form of the hinge assembly 100, so as to ensure that the movement form of the door of the vehicle is stable and reliable, and the performance of the door opening and closing is excellent.

[0084] According to an embodiment of the present invention, the hinge assembly 100 can be applied to the door of a vehicle, and the door of a vehicle can be applied to a vehicle. The door provided with the hinge assembly 100 in the embodiment of the present invention can be applied to a vehicle, and the slider member 40 simultaneously slides along the first fixed-axis rotating arm member 20 and rotates around the second fixed-axis portion 31 relative to the rotation axis of the mounting seat 10, thereby driving the door body to perform a side opening movement. By setting a connecting rod member 60 and one end of the door connecting swing arm 50 to be rotatably connected, when the slider member 40 slides along the first fixed-axis rotating arm member 20 to a position close to the second fixed-axis rotating arm member 30, the angle between the connecting rod member 60 and the door connecting swing arm 50 can be increased, and the door connecting swing arm 50 rotates counterclockwise relative to the slider member 40, which can drive the door body to perform an upward rotation movement, so that the vehicle door can be opened in a scissor-like shape, which can meet the design requirements of the vehicle.
