[0041] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0042] Reference below Figure 1-Figure 7 A hinge assembly 100 according to an embodiment of the present invention will be described. The hinge assembly 100 may be applied to a door of a vehicle, and the door of the vehicle may be applied to a vehicle.

[0043] Combine Figure 1-Figure 7 As shown, the hinge assembly 100 according to the present invention can mainly include: a mounting seat 10, a first fixed-axis rotating arm member 20, a second fixed-axis rotating arm member 30, a sliding member 40, a connecting rod member 60 and a door connecting swing arm 50, wherein the mounting seat 10 can be used to connect the hinge assembly 100 to the side panel of the vehicle, which can facilitate the connection of the hinge assembly 100 to the vehicle and improve the assembly convenience of the hinge assembly 100.

[0044] Furthermore, the first fixed-axis pivot arm 20 is rotatably disposed on the mounting seat 10. Specifically, one end of the first fixed-axis pivot arm 20 is rotatably disposed on the mounting seat 10. This not only allows the first fixed-axis pivot arm 20 to be connected to the mounting seat 10, ensuring that the position of one end of the first fixed-axis pivot arm 20 relative to the plane of the mounting seat 10 does not change, allowing the first fixed-axis pivot arm 20 to be stably disposed in the hinge assembly 100, but also allows the other end of the first fixed-axis pivot arm 20 to be moved away from and closer to the mounting seat 10 by rotating one end of the first fixed-axis pivot arm 20 relative to the mounting seat 10, thereby movably opening and closing the vehicle door via the hinge assembly 100.

[0045] Furthermore, the second fixed-axis pivot arm 30 is rotatably disposed on the mounting seat 10. Specifically, one end of the second fixed-axis pivot arm 30 is rotatably disposed on the mounting seat 10. This not only allows the second fixed-axis pivot arm 30 to be connected relative to the mounting seat 10, ensuring that the position of one end of the second fixed-axis pivot arm 30 relative to the plane of the mounting seat 10 does not change, allowing the second fixed-axis pivot arm 30 to be stably disposed in the hinge assembly 100, but also allows the other end of the second fixed-axis pivot arm 30 to be moved away from and closer to the mounting seat 10 by rotating one end of the second fixed-axis pivot arm 30 relative to the mounting seat 10, thereby movably opening and closing the vehicle door via the hinge assembly 100.

[0046] Furthermore, the slider member 40 is movably connected to the first fixed-axis rotating arm member 20. Specifically, the slider member 40 is connected to the first fixed-axis rotating arm member 20 and is movable on the first fixed-axis rotating arm member 20. This not only allows the slider member 40 to be stably arranged in the hinge assembly 100, but also allows the first fixed-axis rotating arm member 20 to define the movement direction of the slider member 40 in the hinge assembly 100, allowing the slider member 40 to slide along a defined path. This can thereby define the movement path of the vehicle door connected to the hinge assembly 100, ensuring that the vehicle door moves along the defined path.

[0047] In addition, the slider 40 is rotatably connected to the second fixed-axis pivot arm 30, allowing one end of the second fixed-axis pivot arm 30 to freely rotate relative to the slider 40. During the movement of the slider 40 along the first fixed-axis pivot arm 20, one end of the second fixed-axis pivot arm 30 can simultaneously move along the axis of the first fixed-axis pivot arm 20. At the same time, the slider 40, the first fixed-axis pivot arm 20, and the second fixed-axis pivot arm 30 can simultaneously move away from and toward the mounting seat 10, so that the movement of the hinge assembly 100 can drive the vehicle door to open and close. When the slider 40 moves toward the mounting seat 10, the vehicle door closes, and when the slider 40 moves away from the mounting seat 10, the vehicle door opens sideways, thereby enabling the vehicle door to be opened and closed on the vehicle in a side-opening motion.

[0048] Furthermore, the door connecting swing arm 50 is rotatably connected to the slider member 40, and the door connecting swing arm 50 is suitable for connecting to the vehicle door. Specifically, the door connecting swing arm 50 is connected to the slider member 40, so that the door connecting swing arm 50 and the slider member 40 can move synchronously, so that when the slider member 40 approaches and moves away from the mounting seat 10, the door connecting swing arm 50 can move synchronously toward and away from the mounting seat 10. The door connecting swing arm 50 is suitable for connecting to the vehicle door, so that the vehicle door and the door connecting swing arm 50 can move synchronously. When the door connecting swing arm 50 moves toward the mounting seat 10, the vehicle door is driven to close, and when the door connecting swing arm 50 moves toward the mounting seat 10, the vehicle door is driven to open sideways, thereby allowing the vehicle door to be opened and closed on the vehicle in the form of a side-opening movement.

[0049] Furthermore, the door connecting swing arm 50 and the sliding member 40 are rotatable, so that the door connecting swing arm 50 can rotate freely relative to the sliding member 40, and the door connecting swing arm 50 can rotate freely on the sliding member 40 when moving synchronously with the sliding member 40, so that the door can have an upward rotation movement while the door connecting swing arm 50 drives the door to open and close in a side-opening manner.

[0050] Furthermore, one end of the connecting rod 60 is rotatably connected to the door connecting swing arm 50, and the end of the connecting rod 60 away from the door connecting swing arm 50 is rotatably connected to the first fixed-axis rotating arm 20. Specifically, one end of the connecting rod 60 is connected to the door connecting swing arm 50, so that force can be 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. One end of the connecting rod 60 away from the door connecting swing arm 50 is connected to the first fixed axis rotating arm 20. On the one hand, the connecting rod 60 can be stably arranged on the first fixed axis rotating arm 20 and can move synchronously with the first fixed axis rotating arm 20 relative to the mounting base 10. In this way, when the connecting rod 60 and the door connecting swing arm 50 rotate relative to each other, the connecting rod 60 and the door connecting swing arm 50 can be ensured to move synchronously, so that the door connecting swing arm 50 can drive the door to open sideways while rotating upward smoothly to ensure the smooth operation of the door hinge. On the other hand, one end of the connecting rod 60 is relative to the first fixed axis rotating arm 2 0 remains unchanged, and the other end can move synchronously with the door connecting swing arm 50. When the slider 40 slides along the first fixed-axis rotating arm 20, since the lengths of the connecting rod 60 and the door connecting swing arm 50 remain unchanged and cannot be bent, the end of the connecting rod 60 connected to the door connecting swing arm 50 rotates relative to the first fixed-axis rotating arm 20, and the end of the door connecting swing arm 50 connected to the connecting rod 60 rotates relative to the slider 40. The door connecting swing arm 50 can drive the door to rotate relative to the slider 40, so that the door can be rotated upward while opening sideways, so that the door can be in a scissor-like state when opened.

[0051] Therefore, by setting the slider member 40 to be movable on the first fixed-axis rotating arm member 20, the door connecting swing arm 50 is connected to the connecting rod member 60 through one end and connected to the door at the other end, and can be rotated relative to the slider member 40, thereby not only realizing the side opening and upward rotation of the door, but also improving the smoothness of the movement of the hinge assembly 100, thereby meeting the design requirements of the vehicle and enhancing the user's driving experience.

[0052] Combine Figure 1-Figure 3 As shown, the first fixed-axis rotating arm member 20 includes a first fixed-axis portion 21 and a first rotating arm portion 22, and the first fixed-axis portion 21 is rotatably disposed on the mounting seat 10. Specifically, the first fixed-axis rotating arm member 20 is composed of the first fixed-axis portion 21 and the first rotating arm portion 22, which can simplify the structural setting of the first fixed-axis rotating arm member 20 and facilitate the production and assembly of the first fixed-axis rotating arm member 20. The first fixed-axis portion 21 is rotatably disposed on the mounting seat 10, which not only facilitates the fixing of the first fixed-axis rotating arm member 20 on the mounting seat 10, but also allows the first fixed-axis rotating arm member 20 to rotate relative to the mounting seat 10. In this way, the position of the first fixed-axis rotating arm member 20 on the mounting seat 10 remains unchanged while allowing the first fixed-axis rotating arm member 20 to rotate freely on the mounting seat 10.

[0053] Furthermore, the first rotating arm portion 22 is arranged on the first fixed axis portion 21, so that the first fixed axis portion 21 can not only provide a stable and reliable connection position for the first rotating arm portion 22, but also enable force and motion to be directly transmitted between the first fixed axis portion 21 and the first rotating arm portion 22, which can improve the transmission efficiency of force and motion in the first fixed axis rotating arm portion 20, thereby improving the timeliness of the response of the hinge assembly 100 when the user opens the car door. During the rotation of the first fixed axis portion 21 relative to the mounting seat 10, the first rotating arm portion 22 can rotate together with the first fixed axis portion 21 around the rotation axis of the first fixed axis portion 21 relative to the mounting seat 10.

[0054] Furthermore, when the vehicle door is in a closed state, the first rotating arm portion 22 extends toward the second fixed-axis rotating arm portion 30. Such a configuration can enable the first rotating arm portion 22 to guide the sliding of the slider portion 40, thereby ensuring that the slider portion 40 slides on the first fixed-axis rotating arm portion 20 to a position close to or away from the second fixed-axis rotating arm portion 30. The slider portion 40 is slidably arranged on the first rotating arm portion 22, thereby ensuring that the slider portion 40 slides smoothly on the first rotating arm portion 22, thereby ensuring the smoothness of the movement of the slider portion 40 in the hinge assembly 100, thereby improving the operating stability of the hinge assembly 100.

[0055] Combine Figure 2 and Figure 3 As shown, the second fixed-axis rotating arm member 30 includes a second fixed-axis portion 31 and a second rotating arm portion 32. The second fixed-axis portion 31 is rotatably disposed on the mounting base 10. The second rotating arm portion 32 is disposed on the second fixed-axis portion 31 and extends toward the first fixed-axis rotating arm member 20. One end of the second rotating arm portion 32 away from the second fixed-axis portion 31 is rotatably connected to the slider member 40. Specifically, the second fixed-axis rotating arm member 30 is composed of the second fixed-axis portion 31 and the second rotating arm portion 32. This can simplify the structural arrangement of the second fixed-axis rotating arm member 30 and facilitate the production and assembly of the second fixed-axis rotating arm member 30. The second fixed-axis portion 31 is rotatably disposed on the mounting base 10. This not only facilitates fixing the second fixed-axis rotating arm member 30 on the mounting base 10, but also allows the second fixed-axis rotating arm member 30 to rotate relative to the mounting base 10. This ensures that the position of the second fixed-axis rotating arm member 30 on the mounting base 10 remains unchanged while allowing the second fixed-axis rotating arm member 30 to rotate freely on the mounting base 10.

[0056] Furthermore, the second pivot arm portion 32 is arranged on the second fixed axis portion 31, so that not only the second fixed axis portion 31 can provide a stable and reliable connection position for the second pivot arm portion 32, but also the force and motion can be directly transmitted between the second fixed axis portion 31 and the second pivot arm portion 32, which can improve the transmission efficiency of the force and motion in the second fixed axis pivot arm member 30, thereby improving the timeliness of the response of the hinge assembly 100 when the user opens the car door. During the rotation of the second fixed axis portion 31 relative to the mounting seat 10, the second pivot arm portion 32 can rotate together with the second fixed axis portion 31 around the rotation axis of the second fixed axis portion 31 relative to the mounting seat 10.

[0057] Furthermore, when the vehicle door is in a closed state, the second pivot arm portion 32 extends toward the second fixed-axis pivot arm member 30. Such a configuration can facilitate the rotatable connection between the end of the second pivot arm portion 32 away from the second fixed-axis portion 31 and the slider member 40, thereby improving the assembly convenience of the hinge assembly 100 and ensuring the reliability of the transmission of force and motion between the second pivot arm portion 32 and the slider member 40.

[0058] When the slider member 40 has a tendency to slide toward the second fixed-axis rotating arm member 30, the slider member 40 can directly transmit the force to the second rotating arm portion 32, and can make the second rotating arm portion 32 have a movement tendency to approach the second fixed-axis portion 31. In this way, when the slider member 40 starts to slide toward the position of the second fixed-axis rotating arm member 30, the second rotating arm portion 32 can drive the second fixed-axis portion 31 to rotate together around the axis of rotation of the second fixed-axis portion 31 relative to the mounting seat 10, and can make the slider member 40 slide on the first rotating arm portion 22 from a position away from the second fixed-axis rotating arm member 30 to a position close to the second fixed-axis rotating arm member 30, while rotating around the axis of rotation of the second fixed-axis portion 31 relative to the mounting seat 10 together with the second rotating arm portion 32. In an embodiment of the present invention, the door connecting swing arm 50 slides along the slider member 40 along the first rotating arm portion 22 from a position away from the second fixed-axis rotating arm portion 30 to a position close to the second fixed-axis rotating arm portion 30, and the movement form of rotating around the axis of rotation of the second fixed-axis portion 31 relative to the mounting seat 10 is a movement form to realize the side opening of the vehicle door.

[0059] Combine Figure 3As shown, the first fixed axis portion 21 and the second fixed axis portion 31 are spaced apart in a first direction, and the first pivot arm portion 22 and the second pivot arm portion 32 are spaced apart in a second direction, wherein the first direction and the second direction are perpendicular to each other. Specifically, the first fixed axis portion 21 and the second fixed axis portion 31 are both rotatably mounted on the mounting base 10 and spaced apart in the first direction. This prevents the first pivot arm portion 22 from interfering with the second fixed axis portion 31 during rotation, thereby ensuring smooth movement of the hinge assembly 100. The first pivot arm portion 22 and the second pivot arm portion 32 are spaced apart in the second direction. This not only facilitates simultaneous connection of the slider 40 with the first pivot arm portion 22 and the second pivot arm portion 32, but also prevents interference between the first pivot arm portion 22 and the second pivot arm portion 32 during movement of the slider 40 along the first pivot arm portion 22, thereby further improving the smooth movement of the hinge assembly 100.

[0060] Furthermore, the first and second directions are perpendicular to each other. This prevents the sliding direction of the slider 40 along the first pivot arm 22 from interfering with the axial rotation of the first pivot arm 22 relative to the mounting base 10 during movement of the slider 40. During the production of the hinge assembly 100, simply by ensuring that the first and second directions are perpendicular to each other, the hinge assembly 100 can be moved in multiple directions. This not only couples the multiple directional movements of the slider 40 but also ensures smooth movement of the slider 40, thereby reducing the precision requirements for assembly of the hinge assembly 100 and thus reducing the difficulty of manufacturing the hinge assembly 100.

[0061] Combine Figure 1 As shown, the rotation axis of the first fixed axis portion 21 relative to the mounting seat 10 is parallel to the plane where the mounting seat 10 is located, the rotation axis of the second fixed axis portion 31 relative to the mounting seat 10 is parallel to the plane where the mounting seat 10 is located, and the rotation axis of the second fixed axis portion 31 relative to the mounting seat 10 is parallel to the rotation axis of the first fixed axis portion 21 relative to the mounting seat 10.

[0062] Specifically, the rotation axis of the first fixed axis portion 21 relative to the mounting seat 10 is parallel to the plane where the mounting seat 10 is located. This not only prevents the first fixed axis portion 21 from colliding and getting stuck with the mounting seat 10 during rotation, but also ensures that the first fixed axis portion 21 rotates stably and smoothly on the mounting seat 10, and also allows the first fixed axis portion 21 to be as close to the mounting seat 10 as possible, thereby improving the structural compactness of the hinge assembly 100, helping to reduce the structural dimensions of the hinge assembly 100, and making the movement of the hinge assembly 100 more stable and reliable.

[0063] Furthermore, the rotation axis of the second fixed axis portion 31 relative to the mounting seat 10 is parallel to the plane where the mounting seat 10 is located. This not only prevents the second fixed axis portion 31 from colliding and getting stuck with the mounting seat 10 during rotation, but also ensures that the second fixed axis portion 31 rotates stably and smoothly on the mounting seat 10, and also allows the second fixed axis portion 31 to be as close to the mounting seat 10 as possible, thereby improving the structural compactness of the hinge assembly 100, helping to reduce the structural dimensions of the hinge assembly 100, and making the movement of the hinge assembly 100 more stable and reliable.

[0064] In addition, the rotation axis of the second fixed portion and the first fixed axis portion 21 relative to the mounting seat 10 is parallel to the rotation axis of the first fixed axis portion 21 relative to the mounting seat 10, so that the first rotating arm portion 22 and the second rotating arm portion 32 can be ensured to be parallel to each other, and interference between the first rotating arm portion 22 and the second rotating arm portion 32 can be prevented, which may cause the slider member 40 to jam, thereby ensuring the smoothness of the movement of the hinge assembly 100.

[0065] Combine Figure 1 As shown, one end of the door-connecting swing arm 50 is rotatably connected to the connecting rod 60, and the other end of the door-connecting swing arm 50, which is away from the connecting rod 60, is suitable for connecting to the vehicle door. The connection point between the door-connecting swing arm 50 and the slider 40 is located between the two ends of the door-connecting swing arm 50. This arrangement allows the end of the door-connecting swing arm 50 connected to the connecting rod 60 and the end of the door-connecting swing arm 50 connected to the vehicle door to swing in different directions on either side of the first direction of the slider 40. When the end of the door-connecting swing arm 50 connected to the connecting rod 60 swings downward, the end of the door-connecting swing arm 50 connected to the vehicle door swings upward, and the door-connecting swing arm 50 drives the vehicle door to open upward. When the end of the door-connecting swing arm 50 connected to the connecting rod 60 swings upward, the end of the door-connecting swing arm 50 connected to the vehicle door swings downward, and the door-connecting swing arm 50 drives the vehicle door to close downward.

[0066] Combine Figure 1 and Figure 5 As shown, the rotation axis of the connecting rod member 60 relative to the first fixed axis portion 21 is the first rotation axis, the rotation axis of the first fixed axis portion 21 relative to the mounting seat 10 is the second rotation axis, the first rotation axis and the second rotation axis intersect and form a first intersection, the axis along which the slider member 40 moves on the first rotating arm portion 22 is the moving axis, and the first intersection is located on the extension line of the moving axis.

[0067] Specifically, the first intersection formed by the first rotation axis and the second rotation axis is set to be located on the extension line of the moving axis. During the sliding process of the slider member 40 along the first rotating arm portion 22, it can be ensured that the first rotating arm portion 22, the slider member 40, the door connecting swing arm 50 and the connecting rod member 60 all rotate around the second rotation axis under the drive of the first fixed axis portion 21. This can prevent interference and wear between the first rotating arm portion 22, the slider member 40, the door connecting swing arm 50, the connecting rod member 60 and the first fixed axis portion 21, which in turn causes the hinge assembly 100 to move unevenly and generate noise. This setting ensures that the door connecting swing arm 50 rotates smoothly around the second rotation axis, thereby improving the smoothness of the movement of the hinge assembly 100.

[0068] Combine Figure 3 As shown, the rotation axis of the second rotating arm portion 32 relative to the slider member 40 is the third rotation axis, the rotation axis of the door connecting swing arm 50 relative to the slider member 40 is the fourth rotation axis, the third rotation axis intersects with the fourth rotation axis and forms a second intersection, the axis along which the slider member 40 moves on the first rotating arm portion 22 is the moving axis, and the second intersection is located on the extension line of the moving axis.

[0069] Specifically, the second intersection formed by the third rotation axis and the fourth rotation axis is located on the extension line of the moving axis. During the sliding process of the slider member 40 along the first rotating arm portion 22, it can be ensured that the end of the second rotating arm portion 32 connected to the slider member 40 and the door connecting swing arm 50 are both moved along the first rotating arm portion 22 under the drive of the slider member 40. This can prevent interference between the second rotating arm portion 32, the slider member 40 and the door connecting swing arm 50, thereby preventing noise from being generated and affecting the smoothness of movement of the hinge assembly 100. Such a setting can ensure that the slider member 40 moves smoothly on the first rotating arm portion 22, and the smoothness of movement of the hinge assembly 100 can be improved.

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

[0071] Specifically, the first axle seat 11 is used to secure the first fixed shaft portion 21 to the mounting base 10 and allows the first fixed shaft portion 21 to rotate freely relative to the first axle seat 11, thereby rotatably connecting the first fixed shaft arm 20 to the mounting base 10 and forming a first rotational pair 110 of the hinge assembly 100. The second axle seat 12 is used to secure the second fixed shaft portion 31 to the mounting base 10 and allows the second fixed shaft portion 31 to rotate freely relative to the second axle seat 12, thereby rotatably connecting the second fixed shaft arm 30 to the mounting base 10 and forming a second rotational pair 120 of the hinge assembly 100. The slider 40 and the second rotational arm 32 form a third rotational pair 130 of the hinge assembly 100, thereby rotatably connecting the slider 40 and the second rotational arm 32. The door connecting swing arm 50 and the slider 40 form a fourth rotational pair 140 of the hinge assembly 100, thereby rotatably connecting the door connecting swing arm 50 and the slider 40. A fifth rotational pair 150 of the hinge assembly 100 is formed between the door-connecting swing arm 50 and the link 60, rotatably connecting the door-connecting swing arm and the link 60. A sixth rotational pair 160 of the hinge assembly 100 is formed between the link 60 and the first fixed axis portion 21, rotatably connecting the link 60 and the first fixed axis portion 21. This arrangement allows the hinge assembly 100 to have multiple degrees of rotational freedom, thereby facilitating side opening and upward rotation of the door.

[0072] Combine Figure 7 As shown, the distance between the connecting end of the door connecting swing arm 50 corresponding to the door connecting swing arm 50 and the connecting rod member 60 and the slider member 40 is L1, the length of the connecting rod member 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 and the connecting rod 60 and the slider 40 is equal to the length of the connecting rod 60, so that the forces on the two parts of the structure can be equal. In this way, not only can the slider 40 slide along the first rotating arm part 22 and the door connecting swing arm 50 rotate around the slider 40 when the hinge assembly 100 is working, but also when the slider 40 slides along the first rotating arm part 22, the amount of shaking of the door connecting swing arm 50 during the movement can be reduced as much as possible. In this way, the sliding of the slider 40 along the first rotating arm part 22 can be smoother, and the relative rotation of the door connecting swing arm 50 and the connecting rod 60 can be smoother, thereby improving the operating stability of the hinge assembly 100, which is beneficial to improving the user's operating experience of opening and closing the door.

[0073] Combine Figure 6As shown, a plane perpendicular to the rotation axis of the first fixed-axis rotating arm member 20 relative to the mounting seat 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 the first reference plane. An angle α is formed 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, and α satisfies the relationship: 0≤α≤pi / 18. Specifically, the angle formed by 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 angle formed by 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 designed to be less than 0, then the axis of rotation of the first fixed-axis rotating arm member 20 relative to the mounting seat 10, the axis of rotation of the second fixed-axis rotating arm member 30 relative to the mounting seat 10, and the axis of rotation of the second fixed-axis rotating arm member 30 relative to the slider member 40 are coplanar. In this way, the vehicle door will be locked with the vehicle body and cannot be opened. If the axis of the first rotating arm portion 22 and the axis of the second rotating arm portion 32 are designed to be coplanar, the vehicle door will be locked with the vehicle body and cannot be opened. If the angle formed by the projection of the axis of the second rotating arm part 32 on the first reference plane is greater than pi / 18, the side opening angle of the car door is too large, which not only fails to meet the design shape of the car door when it is opened, but also easily collides with people and objects around the car door, increasing the safety hazard of the car door. Therefore, the angle formed by the projection of the axis of the first rotating arm part 22 and the axis of the second rotating arm part 32 on the first reference plane is designed to be between 0 and pi / 18. This not only ensures that the car door can be opened normally, so that people can smoothly enter and exit the vehicle's cockpit after the car door is opened, but also ensures that the car door meets the design shape after opening, and ensures the unfolding effect of the scissor door.

[0074] Combine Figure 5 As shown, an angle β is formed between the connecting rod 60 and the door connecting arm 50, and β satisfies the relationship: pi / 4≤β≤pi / 2. Specifically, the angle between the connecting rod 60 and the door connecting arm 50 is set between pi / 4 and pi / 2. The size of the angle between the connecting rod 60 and the door connecting arm 50 is the size of the upward rotation angle of the door connecting arm 50 away from the end of the connecting rod 60. The minimum angle between the connecting rod 60 and the door connecting arm 50 is set to no more than pi / 4. At this time, the slider 40 is at the farthest distance from the second fixed axis portion 31 on the first fixed axis rotating arm 20. This not only ensures that the vehicle door is closed, but also ensures that the vehicle door is closed. The hinge assembly 100 can be closed reliably and can also prevent the rotation of the connecting rod 60 relative to the first fixed-axis rotating arm 20 and the rotation of the door connecting arm 50 relative to the slider 40 from having a dead angle, thereby ensuring the smooth movement of the hinge assembly 100. The maximum angle between the connecting rod 60 and the door connecting arm 50 is set to not exceed pi / 2, thereby preventing the door connecting arm 50 from rotating upward at an excessively large angle and at an excessively fast speed, which may cause people to be easily injured when the vehicle door is opened, thereby ensuring the safety of users opening and closing the vehicle door.

[0075] Combine 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 provided with a closed position and an open position. When the door connecting swing arm 50 is in the closed position, the slider 40 is located on the first fixed axis rotating arm 20 at a position away from the second fixed axis rotating arm 30. When the door connecting swing arm 50 is in the open position, the slider 40 is located on the second fixed axis rotating arm 30 at a position close to the second fixed axis rotating arm 30. When the slider 40 slides on the first fixed axis rotating arm 20 between a position away from the second fixed axis rotating arm 30 and a position close to the second fixed axis rotating arm 30, the door connecting swing arm 50 can be moved between the closed position and the open position. In this way, the door connecting swing arm 50 can be placed in the closed position and the open position by sliding the slider 40 on the first fixed axis rotating arm 20.

[0076] According to an embodiment of the present invention, the projection of the axis of the door connecting swing arm 50 on the first reference plane when in the closed position and the projection of the axis of the door connecting swing arm 50 on the first reference plane when in the open position form an angle γ, where γ satisfies the relationship: 0<γ≤pi / 4. Specifically, the angle between the projection of the axis of the door connecting swing arm 50 on the first reference plane when in the closed position and the projection of the axis of the door connecting swing arm 50 on the first reference plane when 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 to the vehicle body and cannot be disengaged, resulting 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 vertical position of the door after opening is not obvious, which cannot ensure the door's scissor-shaped display effect. Therefore, setting the side opening angle of the door connecting swing arm 50 between 0 and pi / 4 not only ensures normal opening and closing of the door, but also ensures an appropriate side opening angle, thereby ensuring the design effect of the door after opening.

[0077] According to an embodiment of the present invention, a plane parallel to the rotation axis of the first fixed-axis pivot arm member 20 relative to the mounting seat 10 and perpendicular to the rotation axis of the connecting rod member 60 relative to the first fixed-axis pivot arm member 20 is set as the second reference plane, and 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 angle δ, and δ satisfies the relationship: 0<δ≤5pi / 18. Specifically, the angle between the projection of the axis of the door connecting swing arm 50 on the second reference plane when the door connecting swing arm 50 is in the closed position and the projection of the axis of the door connecting swing arm 50 on the second reference plane when the door connecting swing arm 50 is in the open position is the upward rotation angle of the door connecting swing arm 50. If the upward rotation angle of the door connecting swing arm 50 is less than 0, the door connecting swing arm 50 cannot be in an upward rotation posture, and the door is only in a side-opening form, and the design of a scissor-type door cannot be realized. If the upward rotation angle of the door connecting swing arm 50 is greater than 5pi / 18, the upward rotation angle of the door connecting swing arm 50 is too large, which not only affects the opening form of the door, but also makes the door open for too long, affecting the normal use of the vehicle. Therefore, the upward rotation angle of the door connecting swing arm 50 is designed to be between 0 and 5pi / 18, which can not only realize the upward rotation of the door after opening, but also ensure the normal operation of the door.

[0078] Combine Figure 1 and Figure 2 As shown, the door connecting arm 50 is provided with at least one connector 51, which is used to connect to a power spring. Specifically, the connector 51 on the door connecting arm 50 facilitates connecting the power spring to the door connecting arm 50. The expansion and contraction of the power spring can directly transmit force to the door connecting arm 50, thereby increasing the driving force of the door connecting arm 50 when the door connecting arm 50 moves between the closed position and the open position. This can speed up the movement of the door connecting arm 50 while saving manpower, making the vehicle door opening easier and more convenient. In addition, the number of connectors 51 is at least one. This allows different numbers of connectors 51 to be installed on the door connecting arm 50 according to the weight of the vehicle door, thereby connecting different numbers of power springs. This allows the driving force applied by the power spring to the door connecting arm 50 to be adjusted, allowing users to easily and effortlessly open doors of different weights, thereby improving the user's operating experience. In embodiments of the present invention, power springs include but are not limited to electric springs, pneumatic springs, and balancing springs.

[0079] According to an embodiment of the present invention, a vehicle door includes a hinge assembly 100 and a door body, wherein the door body is connected to a door connecting arm 50. Specifically, the hinge assembly 100 of the present invention can be applied to a vehicle door. In a vehicle door, the door body can be used to seal the vehicle's cockpit, ensuring the safety of people while the vehicle is in motion. The door body can display the vehicle door's open and closed states. The door body is connected to the door connecting arm 50, ensuring reliable transmission of force and motion between the door body and the door connecting arm 50.

[0080] When the vehicle door is opened, a person applies a pulling force to the door body with his hand, which makes the door body tend to disengage from the door lock. The pulling force can be directly transmitted to the door connecting swing arm 50 through the door body, and the power spring applies an elastic force to the connecting member 51 on the door connecting swing arm 50 through a telescopic action. The connecting member 51 can directly transmit the elastic force of the power spring to the door connecting swing arm 50, and the door connecting swing arm 50 transmits the pulling force and the elastic force it receives to the slider 40. When the sum of the external forces received by the slider 40 reaches a preset value for opening the vehicle door, the slider 40 slides along the axis of the first rotating arm part 22 from a position away from the second fixed-axis rotating arm part 30 to a position close to the second fixed-axis rotating arm part 30 under the action of the external force. While the slider 40 moves, it can transmit the force to the second fixed-axis rotating arm part 30, so that the end of the second rotating arm part 32 connected to the slider 40 rotates The second fixed axis portion 31 rotates relative to the axis of rotation of the mounting base 10, simultaneously driving the slider 40 to rotate about the axis of rotation of the second fixed axis portion 31 relative to the mounting base 10. The slider 40 tends to move away from the mounting base 10, which can drive the end of the first rotating arm portion 22 closest to the slider 40 to rotate about the axis of rotation of the first fixed axis portion 21 relative to the mounting base 10. At this time, the axis of rotation of the first fixed axis rotating arm 20 relative to the mounting base 10, the axis of rotation of the second fixed axis rotating arm 30 relative to the mounting base 10, and the axis of rotation of the second fixed axis rotating arm 30 relative to the slider 40 are parallel to each other and are not in the same plane. The door connecting swing arm 50 slides along the first fixed axis rotating arm 20 along with the slider 40 and rotates about the axis of rotation of the second fixed axis rotating arm 30 relative to the mounting base 10, thereby causing the door body to open sideways. In this embodiment of the present invention, the preset value for door opening is the force at the instant when the door connecting swing arm 50 moves from the closed position to the open position.

[0081] In an embodiment of the present invention, the hinge assembly 100 can be shared with the body side panel and the inner door sheet metal of the side-opening door, so that the scissor-type door can follow the arrangement of the door lock of the side-opening door on the body, thereby saving the body mold cost.

[0082] According to an embodiment of the present invention, the size of α and the size of β are not in a linear relationship. During the process of opening the vehicle door, the larger the angle between the connecting rod 60 and the door connecting swing arm 50 is designed to be, the faster the rate of change of the upward rotation angle of the door connecting swing arm 50 is, and at the same time, the rate of change of the angle formed by the projection of the axis of the first rotating arm part 22 and the axis of the second rotating arm part 32 on the first reference plane is slower. When the door connecting swing arm 50 moves from the closed position to the open position, the slider member 40 slides along the axis of the first swing arm part 22 from a position away from the second fixed-axis swing arm part 30 to a position close to the second fixed-axis swing arm part 30. The angle change rate of the angle formed by the projection of the axis of the first swing arm part 22 and the axis of the second swing arm part 32 on the first reference plane is fast at first and then slow. This allows the door body to be quickly disconnected from the door lock under the drive of the door connecting swing arm 50, ensuring that the door body can be opened smoothly. The angle change rate between the connecting rod member 60 and the door connecting swing arm 50 is slow at first and then fast. In this way, after the door body is completely disconnected from the door lock, it can be quickly rotated upward, and the posture of the door body after rotating upward can be ensured to be steep, thereby ensuring that the vehicle door is opened in a scissor-like manner.

[0083] In an embodiment of the present invention, a crank slider mechanism composed of a connecting rod member 60, a door connecting swing arm 50 and a slider member 40 is an upward rotating plane mechanism of the hinge assembly 100, and a swing guide rod mechanism composed of a first fixed-axis rotating arm member 20, a slider member 40 and a second fixed-axis rotating arm member 30 is a side-opening plane mechanism of the hinge assembly 100. The upward rotating plane mechanism and the side-opening plane structure are connected in parallel through the slider member 40. When the door connecting swing arm 50 moves from a closed position to an open position, the door body presents a parabolic motion trajectory. Such an arrangement, on the one hand, can not only improve the structural compactness of the hinge assembly 100, but also make the processing accuracy of the hinge assembly 100 easy to control, and can facilitate the realization and assembly of the hinge assembly 100. On the other hand, it can fix the motion form of the hinge assembly 100, ensure that the motion form of the vehicle door is stable and reliable, and maintain excellent door opening and closing performance.

[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.
