[0038] The following describes in detail embodiments of the present application, and the embodiments described with reference to the accompanying drawings are exemplary.

[0039] A vehicle door hinge assembly 100 according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 7 . The vehicle door hinge assembly 100 may be applied to a vehicle door, and the vehicle door may be applied to a vehicle.

[0040] As shown in Figures 1 to 6 , the hinge assembly 100 of the vehicle door according to the present application may mainly include: a mounting seat 10, a first connecting rod 20, a second connecting rod 30 and a door connecting swing arm 40, wherein the mounting seat 10 can be used to connect the hinge assembly 100 of the vehicle door to the side panel of the vehicle, which can facilitate the connection of the hinge assembly 100 of the vehicle door to the vehicle, and facilitate the rotatable connection of the vehicle door to the vehicle to realize the opening and closing of the vehicle door on the vehicle.

[0041] The first connecting rod 20 is rotatably connected to the mounting base 10 to form a first kinematic joint 21. This not only allows the first connecting rod 20 and the mounting base 10 to rotate relative to each other, but also allows the first connecting rod 20 to be connected to the mounting base 10, ensuring the structural reliability of the first connecting rod 20 on the mounting base 10. The second connecting rod 30 is rotatably connected to the mounting base 10 to form a second kinematic joint 31. This not only allows the second connecting rod 30 and the mounting base 10 to rotate relative to each other, but also allows the second connecting rod 30 to be connected to the mounting base 10, ensuring the structural reliability of the second connecting rod 30 on the mounting base 10.

[0042] The door-connecting swing arm 40 is rotatably connected to the second link 30 to form a third kinematic joint 41, and the door-connecting swing arm 40 is rotatably connected to the first link 20 to form a fourth kinematic joint 42. Specifically, the third kinematic joint 41 not only connects the door-connecting swing arm 40 to the second link 30 but also enables relative rotation between the two. The fourth kinematic joint 42 not only connects the door-connecting swing arm 40 to the first link 20 but also enables relative rotation between the two. With this arrangement, the door-connecting swing arm 40 is not only connected to the mounting base 10 and disposed together with the mounting base 10 on the door side, but is also rotatable relative to the first kinematic joint 21 and the second kinematic joint 31 on the mounting base 10, thereby changing the position of the door-connecting swing arm 40 relative to the mounting base 10 in the vehicle.

[0043] At least one of the first kinematic pair 21, the second kinematic pair 31, the third kinematic pair 41, and the fourth kinematic pair 42 is a cylindrical pair. Specifically, the two structures connected by the cylindrical pair can not only rotate relative to each other, but also move relative to each other. By configuring at least one of the first kinematic pair 21, the second kinematic pair 31, the third kinematic pair 41, and the fourth kinematic pair 42 as a cylindrical pair, the door connecting swing arm 40 can simultaneously rotate relative to the mounting base 10 and move. This allows the door connecting swing arm 40 to simultaneously rotate relative to the mounting base 10 about the rotation axes of the multiple kinematic pairs. This allows for force coupling in the door hinge assembly 100, allowing the door connecting swing arm 40 to ultimately open in a sideways and upward rotation manner, resulting in a scissor-like opening state of the door.

[0044] The cylindrical pair structure enhances the guiding effect of the two connected structures along the cylindrical pair's rotational axis, making the door connecting swing arm 40 more stable during movement, thereby improving the smooth movement of the door, enhancing the vehicle door opening experience and the door's structural stability. Furthermore, the cylindrical pair is easy to install and adjust, facilitating the assembly of the door hinge assembly 100.

[0045] According to some embodiments of the present application, in combination with Figures 1 and 2, the first kinematic pair 21, the second kinematic pair 31, the third kinematic pair 41, and the fourth kinematic pair 42 include two revolute pairs, a cylindrical pair, and a spherical pair. According to other embodiments of the present application, the first kinematic pair 21, the second kinematic pair 31, the third kinematic pair 41, and the fourth kinematic pair 42 include two revolute pairs, a cylindrical pair, and a universal joint. According to still other embodiments of the present application, the first kinematic pair 21, the second kinematic pair 31, the third kinematic pair 41, and the fourth kinematic pair 42 include two revolute pairs, a cylindrical pair, and a kinematic pair with at least two degrees of freedom.

[0046] According to some embodiments of the present application, the first kinematic joint 21 and the second kinematic joint 31 are both rotational joints, which can enable the door connecting swing arm 40 to rotate relative to the mounting seat 10 simultaneously about the rotation axis of the first kinematic joint 21 and the rotation axis of the second kinematic joint 31, so as to realize the side opening and upward rotation of the door connecting swing arm 40. The fourth kinematic joint 42 is a ball joint. Such a configuration can, on the one hand, form a rotating spherical center between the door connecting swing arm 40 and the first connecting rod 20, thereby increasing the rotational freedom of the door connecting swing arm 40 relative to the mounting seat 10, and can couple the rotation of the first kinematic joint 21 and the second kinematic joint 31, so that the door connecting swing arm 40 can be opened sideways and rotated upward at the same time. On the other hand, the ball joint can facilitate the assembly of the hinge assembly 100 of the vehicle door, and can make the processing accuracy of the hinge assembly 100 of the vehicle door easier to control.

[0047] The third kinematic pair 41 is a cylindrical pair, which can enable the door connecting swing arm 40 to rotate relative to the second connecting rod 30 while moving relative to the second connecting rod 30, so that when the door connecting swing arm 40 rotates simultaneously with the rotation axis of the first kinematic pair 21 and the rotation axis of the second kinematic pair 31 as axes, the limitation of the length of the second connecting rod 30 on the rotation angle of the door connecting swing arm 40 is eliminated, so that the door connecting swing arm 40 can be rotated to the preset door opening angle, making it convenient for users to enter and exit the vehicle.

[0048] In addition, setting the third kinematic pair 41 as a cylindrical pair can ensure that the door connecting arm 40 rotates smoothly relative to the second connecting rod 30. In this way, during the movement of the door hinge assembly 100, interference between the second connecting rod 30 and the door connecting arm 40 can be prevented, which causes the door hinge assembly 100 to get stuck, thereby improving the movement smoothness and stability of the door hinge assembly 100, which is beneficial to improving the user's operating experience of opening and closing the door.

[0049] In an embodiment of the present application, the fourth kinematic pair 42 formed between the door connecting arm 40 and the first connecting rod 20 includes a ball head member 421, which is fixedly connected to the first connecting rod 20. One end of the door connecting arm 40 is sleeved on the ball head member 421 and rotates around the rotating center of the ball head member 421. The third kinematic pair 41 formed between the second connecting rod 30 and the door connecting arm 40 includes a fixed shaft 411, wherein the connection method between the fixed shaft 411 and the door connecting arm 40 includes but is not limited to riveting and bolt connection, and the fixed shaft 411 can be used to limit the moving direction of the door connecting arm 40.

[0050] According to other embodiments of the present application, the first kinematic joint 21 and the third kinematic joint 41 are both revolute joints, the fourth kinematic joint 42 is a spherical joint, and the second kinematic joint 31 is a cylindrical joint. This not only allows the door connecting swing arm 40 to open sideways and rotate upward at the same time, but also prevents the door hinge assembly 100 from getting stuck during movement, thereby improving the movement smoothness and stability of the door hinge assembly 100, which is beneficial to improving the user's operating experience of opening and closing the door.

[0051] According to some further embodiments of the present application, the second kinematic joint 31 and the third kinematic joint 41 are both revolute joints, the fourth kinematic joint 42 is a spherical joint, and the first kinematic joint 21 is a cylindrical joint. This not only allows the door connecting swing arm 40 to open sideways and rotate upward at the same time, but also prevents the door hinge assembly 100 from getting stuck during movement, thereby improving the movement smoothness and stability of the door hinge assembly 100, which is beneficial to improving the user's operating experience of opening and closing the door.

[0052] According to some further embodiments of the present application, the first kinematic joint 21 and the second kinematic joint 31 are both rotating joints, the third kinematic joint 41 is a spherical joint, and the fourth kinematic joint 42 is a cylindrical joint. This not only allows the door connecting swing arm 40 to open sideways and rotate upward at the same time, but also prevents the door hinge assembly 100 from getting stuck during movement, thereby improving the movement smoothness and stability of the door hinge assembly 100, which is beneficial to improving the user's operating experience of opening and closing the door.

[0053] 1 , 2 , and 4 , the rotation axis of the first kinematic pair 21 is parallel to the plane of the mounting base 10, and the rotation axis of the second kinematic pair 31 is parallel to the plane of the mounting base 10. Specifically, the rotation axis of the first kinematic pair 21 is parallel to the plane of the mounting base 10, which allows the first connecting rod 20 to rotate parallel to the plane of the mounting base 10. This not only prevents the first connecting rod 20 from interfering with the mounting base 10 during rotation, thereby ensuring the rotational stability of the first connecting rod 20 and, in turn, the movement stability of the door connecting swing arm 40, but also allows the first connecting rod 20 to be arranged as close to the mounting base 10 as possible, thereby making the structure of the hinge assembly 100 more compact, which is conducive to reducing the size of the door hinge assembly 100 and reducing the space occupied by the door hinge assembly 100 in the vehicle, thereby improving the space utilization rate of the vehicle.

[0054] The rotation axis of the second kinematic pair 31 is parallel to the plane where the mounting seat 10 is located, so that the second connecting rod 30 can rotate parallel to the plane where the mounting seat 10 is located. This not only prevents the second connecting rod 30 from interfering with the mounting seat 10 during rotation, but also ensures the rotation stability of the second connecting rod 30, thereby ensuring the movement stability of the door connecting swing arm 40, and also allows the second connecting rod 30 to be set as close to the mounting seat 10 as possible, so that the structure of the hinge assembly 100 can be more compact, which is conducive to reducing the size of the door hinge assembly 100, reducing the space occupied by the door hinge assembly 100 in the vehicle, and helping to improve the space utilization of the vehicle.

[0055] As shown in FIG1 , an angle is formed between the rotational axis of the first kinematic joint 21 and the rotational axis of the second kinematic joint 31. Specifically, by providing an angle between the rotational axis of the first kinematic joint 21 and the rotational axis of the second kinematic joint 31, the door connecting swing arm 40 can rotate about axes in different directions relative to the plane of the mounting base 10. Furthermore, by designing the rotational axis of the first kinematic joint 21 and the rotational axis of the second kinematic joint 31 to have an angle in the plane of the mounting base 10, the door can be opened sideways and rotated upward, thereby ensuring that the vehicle door meets the design requirements of a scissor-type door when opened.

[0056] As shown in Figures 1 and 2 , the second connecting rod 30 is axially movable relative to the door connecting arm 40 along the axis of the third kinematic joint 41. Specifically, when the second connecting rod 30 drives the door connecting arm 40 to rotate about the rotation axis of the second kinematic joint 31, and the first connecting rod 20 drives the door connecting arm 40 to rotate about the rotation axis of the first kinematic joint 21, the second connecting rod 30 is sleeved on one end of the fixed shaft 411 and is axially movable along the axis of the third kinematic joint 41. Such a setting can not only ensure the connection reliability of the second connecting rod 30 and the door connecting swing arm 40, and thus ensure the movement reliability of the door connecting swing arm 40, but also change the connection position of the second connecting rod 30 and the door connecting swing arm 40, and eliminate the rotation restriction of the second connecting rod 30 on the door connecting swing arm 40 around the fourth motion pair 42. This not only ensures the smoothness of the movement of the door connecting swing arm 40 and prevents the door connecting swing arm 40 from having a rotation dead point, but also expands the rotation range of the door connecting swing arm 40, so that the door connecting swing arm 40 can be rotated to the preset angle of the door opening to facilitate users to enter and exit the vehicle.

[0057] As shown in Figures 1 to 3 , at least one connection seat 43 is provided on the door connecting arm 40, and the connection seat 43 is used to connect a driving member. Specifically, the connection seat 43 is provided on the door connecting arm 40, which can facilitate the connection of the driving member to the door connecting arm 40, and the driving member can provide a driving force to the door connecting arm 40. In the embodiment of the present application, the driving member includes but is not limited to an electric spring, a pneumatic spring and a balancing spring. The electric spring, the pneumatic spring and the balancing spring can all be extended and retracted to generate an elastic force. When the door connecting arm 40 moves between the closed position and the open position, the elastic force generated by the driving member can increase the magnitude of the driving force acting on the door connecting arm 40, thereby speeding up the movement speed of the door connecting arm 40 while saving manpower, so that the vehicle door can be opened more easily and conveniently.

[0058] There is at least one connecting seat 43, so that different numbers of connecting seats 43 can be installed on the door connecting swing arm 40 according to the different weights of the vehicle doors, so as to connect different numbers of driving parts, so that the driving force applied by the driving part to the door connecting swing arm 40 can be adjusted, so that users can easily and effortlessly open doors of different weights, thereby improving the user's operating experience.

[0059] As shown in Figures 3 and 6 , the connection base 43 is provided with reinforcing ribs 431. For example, multiple, spaced-apart reinforcing ribs 431 can enhance the connection stability between the driver and the door connecting arm 40, increase the contact area between the connection base 43 and the driver, and enhance the connection strength between the driver and the door connecting arm 40, thereby improving the movement stability of the door hinge assembly 100. In the embodiment of the present application, the reinforcing ribs 431 include but are not limited to ribs on both sides of the mounting surface of the connection base 43.

[0060] As shown in FIG3 , the door hinge assembly 100 has an initial state and an operating state. In the initial state, the plane formed by the rotation axis of the third kinematic joint 41 and the rotation axis of the second kinematic joint 31 is a first plane, the plane on which the mounting base 10 is located is a second plane, and the angle between the first and second planes is less than π / 18. Specifically, the two states of the door hinge assembly 100 correspond to the opening and closing states of the door, respectively. When the door hinge assembly 100 is in the initial state, the door is closed, and when the door hinge assembly 100 is in the operating state, the door is open.

[0061] The plane where the mounting seat 10 is located is the plane formed by the connection between the first connecting rod 20 and the mounting seat 10 and the connection between the second connecting rod 30 and the mounting seat 10. When the hinge assembly 100 of the vehicle door is set in the initial state, the angle between the plane formed by the rotation axis of the third kinematic pair 41 and the rotation axis of the second kinematic pair 31 and the plane where the mounting seat 10 is located is less than π / 18. When the vehicle door is closed, the second connecting rod 30 can be made as close as possible to the plane where the mounting seat 10 is located. In this way, the space occupied by the hinge assembly 100 of the vehicle door when the vehicle door is closed can be reduced as much as possible, thereby ensuring the closing reliability and structural stability of the vehicle door.

[0062] If the angle between the plane formed by the rotation axis of the third kinematic pair 41 and the rotation axis of the second kinematic pair 31 and the plane where the mounting seat 10 is located is greater than π / 18, it will not only increase the space occupied by the hinge assembly 100 of the door when the door is closed, but also limit the range of motion of the hinge assembly 100 of the door in the working state, thereby limiting the opening angle of the door.

[0063] As shown in Figures 1, 2, 3, 4, 5, and 7, the mounting base 10 is provided with an axle seat 12, and the second connecting rod 30 is connected to the mounting base 10 via the axle seat 12. The axle seat 12 is provided with a first limiting portion 11, which has a first limiting plane. The second connecting rod 30 has a second limiting portion 32, which has a second limiting plane. Specifically, the axle seat 12 is stably arranged on the mounting base 10. Connecting the second connecting rod 30 to the mounting base 10 via the axle seat 12 not only ensures that the second connecting rod 30 is securely mounted on the mounting base 10, but also allows the second connecting rod 30 to rotate normally around the axis of the second kinematic joint 31, thereby allowing the vehicle door to open normally. In the embodiment of the present application, the first connecting rod 20 is connected to the mounting base 10 via the axle seat 12, which not only ensures that the first connecting rod 20 is stably mounted on the mounting base 10, but also allows the first connecting rod 20 to rotate normally around the axis of the first kinematic joint 21, thereby ensuring that the vehicle door can open normally.

[0064] According to some embodiments of the present application, when the door hinge assembly 100 is in its initial state and the door is closed, the angle between the first limiting plane and the second limiting plane is between π / 2 and 2π / 3. This allows the door to open at a desired angle to meet the requirements for boarding and exiting the vehicle. If the angle between the first limiting plane and the second limiting plane is set to less than π / 2, the door opening angle is too small and cannot meet the requirements for boarding and exiting the vehicle. If the angle between the first limiting plane and the second limiting plane is set to greater than 2π / 3, the door opening angle is too large, potentially damaging the vehicle body.

[0065] The hinge assembly 100 of the vehicle door is in a working state, and when the opening angle of the vehicle door reaches the maximum angle between the first limiting plane and the second limiting plane when the vehicle door hinge assembly 100 is in an initial state, the first limiting plane and the second limiting plane cooperate with each other to limit. This not only makes the opening angle of the vehicle door meet the human-machine requirements of getting on and off the vehicle, but also prevents the second connecting rod 30 from continuing to rotate around the axis of the second kinematic pair 31, thereby preventing the vehicle door from opening at an excessively large angle and colliding with the vehicle body.

[0066] According to other embodiments of the present application, when the second link 30 rotates relative to the mounting base 10 to (π / 2-π / 36)~(2π / 3-π / 36), the second link 30 can be pushed a certain distance away from the first limit portion 11 by the extension and contraction of the driving member, so that the hinge assembly 100 of the vehicle door can avoid the hard limit point, and by controlling the magnitude of the force applied by the driving member to the second link 30, the second link 30 can be stopped from rotating. At this time, the driving member can perform a soft stop limit on the hinge assembly 100 of the vehicle door, thereby preventing the vehicle door from having a noticeable jamming feeling during the scissor-like opening and closing process, which is conducive to improving the vehicle door opening and closing operation experience. When one of the side opening angle and the upward rotation angle of the vehicle door is too large, the second link 30 contacts the first limit portion 11 to prevent the side opening angle and the upward rotation angle of the vehicle door from being too large, thereby ensuring the movement reliability of the hinge assembly 100 of the vehicle door. It should also be noted that when the vehicle door is opened until the first limiting portion 11 and the second limiting portion 32 contact and limit, it is the hard limit point of the hinge assembly 100 of the vehicle door.

[0067] As shown in Figures 1-3 , a door harness mounting hole 44 is provided on the door connecting arm 40. Specifically, the door harness mounting hole 44 provides an installation location for the vehicle's wiring harness to pass through the door connecting arm 40. This secures the wiring harness's position within the door hinge assembly 100, ensures a stable and reliable structure for the wiring harness on the door connecting arm 40, and prevents the wiring harness from becoming entangled when passing through the door hinge assembly 100, thereby facilitating wiring harness organization within the door hinge assembly 100.

[0068] According to an embodiment of the present application, a vehicle door includes a door hinge assembly 100 and a vehicle door, wherein the vehicle door is connected to a door connecting swing arm 40. Specifically, the vehicle door hinge assembly 100 of the present application can be applied to a vehicle door. In the vehicle door, the vehicle door can be used to close the vehicle's cockpit to ensure the safety of the user while the vehicle is driving. The vehicle door can display the vehicle door's open and closed status. The vehicle door is connected to the door connecting swing arm 40 to ensure reliable transmission of force and motion between the vehicle door and the door connecting swing arm 40.

[0069] When opening the vehicle door, the user applies a pulling force to the door with his hand, causing the door to tend to disengage from the door lock. The pulling force can be directly transmitted to the door connecting swing arm 40 through the door, and the driving member applies an elastic force to the connecting seat 43 on the door connecting swing arm 40 through a telescopic action. The connecting seat 43 can directly transmit the elastic force of the driving member to the door connecting swing arm 40, and the door connecting swing arm 40 rotates together with the second link 30 around the axis of rotation of the second link 30 relative to the mounting seat 10. The end of the door connecting swing arm 40 adjacent to the second link 30 rotates relative to the first link 20, and the end of the second link 30 away from the mounting seat 10 slides relative to the door connecting swing arm 40, so that the door connecting swing arm 40 can move between the closed position and the open position to realize the side opening and upward rotation of the vehicle door.

[0070] In an embodiment of the present application, the hinge assembly 100 of the vehicle door can be shared with the vehicle body side panel and the inner door sheet metal of the side-opening door, so that the scissor-type door can be arranged along the state where the side-opening door is locked on the vehicle body, thereby saving the vehicle body mold cost.

[0071] According to an embodiment of the present application, as shown in FIG8 , a vehicle door 200 of a vehicle 1000 is connected to a door hinge assembly 100 , and the vehicle door 200 of the vehicle 1000 can be used in the vehicle 1000. The vehicle door 200 provided with the door hinge assembly 100 according to the embodiment of the present application can be used in the vehicle 1000. By providing a first connecting rod 20 and a second connecting rod 30 that are both rotatably connected to a door connecting swing arm 40 , the door connecting swing arm 40 can be driven by the door connecting swing arm 40 to open sideways and rotate upward along a preset trajectory when an external force is applied to the door connecting swing arm 40 . When the door connecting swing arm 40 moves from a closed position to an open position, the door 200 is caused to move in an arc-shaped trajectory, thereby allowing the door 200 of the vehicle 1000 to open in a scissor-like configuration, thereby meeting the design requirements of the vehicle 1000 .
