[0087] Reference Signs Figures 1 to 6The application provides a hinge structure for driving a vehicle door 500 to approach or move away from a vehicle body 600. The hinge 100 comprises a base 300, a sliding seat 310, a first connecting rod 110, a second connecting rod 120, and a mounting seat 200. The base 300 is used for connecting to the vehicle body 600. A first end of the first connecting rod 110 is rotatably connected to the base 300 around a first rotation axis AX1. A first end of the second connecting rod 120 is rotatably connected to the sliding seat 310 around a second rotation axis AX2, the sliding seat 310 is used for slidably connecting to the vehicle body 600 in a first direction D1, and a second end of the second connecting rod 120 is hinged to a second end of the first connecting rod 110 around a third rotation axis AX3. The mounting seat 200 is used for connecting to the vehicle door 500. The mounting seat 200 is connected to the second end of the first connecting rod 110 and the second end of the second connecting rod 120 respectively, and the first connecting rod 110 and the second connecting rod 120 are spaced apart, and the second end of the second connecting rod 120 and the second end of the first connecting rod 110 are both rotatable around the third rotation axis AX3; wherein during the sliding of the sliding seat 310, the angle between the first connecting rod 110 and the second connecting rod 120 changes, thereby driving the mounting seat 200 to rotate around a fourth rotation axis AX4.

[0088] The hinge 100 provided by the present application has an extended position and a retracted position, so that the mounting seat 200 approaches or moves away from the base 300, and then the vehicle door 500 approaches or moves away from the vehicle body 600. In the present application, through the arrangement of the first connecting rod 110 and the second connecting rod 120 in the hinge 100, the vehicle door 500 can realize smooth movement during opening and closing, and unnecessary vibration or impact can be avoided. The first connecting rod 110 and the second connecting rod 120 form a triangular structure, which improves the stability, balances the load, enhances the rigidity and controls the movement path of the hinge 100 system, thereby optimizing the function and performance of the entire hinge structure. Specifically, firm support can be provided during the movement of the vehicle door 500 to prevent excessive deformation or shaking and ensure the stability of the hinge structure; the triangular structure can balance the load and share the pressure when the vehicle door 500 is opened or closed, which can avoid excessive force concentrated on a certain connection point, reduce the stress of the hinge 100 and related connecting parts, and provide more uniform support; the similar triangular structure can effectively increase the rigidity of the connecting parts and the hinge 100 system, which can improve the anti-deformation ability of the entire system and avoid unnecessary bending or twisting; by adjusting the included angle between the first connecting rod 110 and the second connecting rod 120, the movement path of the vehicle door 500 can be accurately controlled, so that the vehicle door 500 can move with a specific radian when opening and closing, and collision with other parts of the vehicle body 600 or obstacles can be avoided.

[0089] The rotation directions of the first connecting rod 110 and the second connecting rod 120 are opposite. This enables the door 500 to rotate in a certain dimension, and precise rotation control, parallel motion maintenance, transmission efficiency improvement, and flexible door opening angle adjustment can be achieved.

[0090] The second ends of the first connecting rod 110 and the second connecting rod 120 are respectively connected to the two ends of the mounting seat 200. Alternatively, at least part of the first connecting rod 110 and the second connecting rod 120 are located on opposite sides of the mounting seat 200.

[0091] During the movement of the hinge structure, the included angle between the first connecting rod 110 and the second connecting rod 120 is greater than 0° and less than 180°. By limiting the included angle between the first connecting rod 110 and the second connecting rod 120, the movement trajectory of the hinge structure is unique, and the stability during movement can be ensured.

[0092] The second end of the first connecting rod 110 is fixedly provided with a first bevel gear 111. The second end of the second connecting rod 120 is fixedly provided with a second bevel gear 121. The mounting seat 200 is provided with a third bevel gear 201. The first bevel gear 111 and the second bevel gear 121 are engaged with the third bevel gear 201, and the first bevel gear 111 and the second bevel gear 121 are configured to rotate the third bevel gear 201 about a fourth rotation axis AX4. By means of the engagement of the bevel gears, the door 500 can rotate in a certain dimension, precise rotation control, parallel motion maintenance, transmission efficiency improvement, and flexible door opening angle adjustment can be achieved, and the functionality and reliability of the door 500 are improved, thereby providing better use experience and convenience. Specifically, the engagement mechanism of the bevel gears can provide precise rotation transmission, accurately control the rotation angle and speed when the door 500 is opened and closed, and ensure smooth, stable, and controllable movement of the door 500; through the cooperation of the bevel gears, the door 500 remains parallel to the original position during rotation, avoiding tilting or instability. Ensure that the door 500 always maintains a consistent positional relationship with the vehicle body 600 during opening and closing; the bevel gear transmission has good transmission efficiency, can effectively transmit driving force to the door 500, reduce energy loss during movement, and improve the performance and life of the entire hinge structure; by changing the center distance and transmission ratio between the bevel gears, the door opening angle can be adjusted. In this way, the flexible requirements for the opening angle of the door 500 in different scenarios can be met, and adaptability and convenience are improved. In addition, by adjusting the center distance and transmission ratio between the bevel gears, different side opening angles can be adjusted.

[0093] In some embodiments of the present application, the third rotation axis AX3 is located between the first rotation axis AX1 and the second rotation axis AX2 in the projection of the plane where the base 300 is located. By locating the third rotation axis AX3 between the first rotation axis AX1 and the second rotation axis AX2, the space of the hinge 100 device can be better utilized, which helps to arrange the hinge 100 compactly between the door 500 and the vehicle body 600, and maximizes the space occupation. That is, the hinged ends of the first connecting rod 110 and the second connecting rod 120 are located between the first connecting rod 110 and the second connecting rod 120, which provides stable balance in the moment distribution when the door 500 is opened or closed, so as to ensure that the hinge 100 system remains stable during movement.

[0094] In some embodiments of the present application, the first rotation axis AX1 is perpendicular to the first direction D1, the first rotation axis AX1 is parallel to the second rotation axis AX2, and the fourth rotation axis AX4 is perpendicular to the plane defined by the first rotation axis AX1 and the second rotation axis AX2. By making the fourth rotation axis AX4 perpendicular to the defined plane, the door 500 remains relatively perpendicular to the ground when opening and closing, avoiding tilting or irregular movement.

[0095] In some embodiments of the present application, the first rotation axis AX1 and the second rotation axis AX2 are arranged in the height direction or the length direction of the vehicle body.

[0096] In some embodiments of the present application, the first rotation axis AX1 extends in the front-rear direction of the vehicle. It can be understood that the second rotation axis AX2 extends in the front-rear direction of the vehicle. Therefore, the hinge structure can be arranged vertically, and the assembly precision of the hinge 100 base 300 node is relatively low, which is convenient for processing and assembly. Through the rotation of the first connecting rod 110 and the second connecting rod 120, the door 500 can be close to or away from the vehicle body 600.

[0097] In some embodiments of the present application, the plane where the first rotation axis AX1 and the second rotation axis AX2 are located in the initial position is parallel to the mounting surface of the mounting seat 200 for connecting the door 500. In the movement process of the hinge structure, the mounting surfaces of the mounting seat 200 for connecting the door 500 at any two positions are parallel. This ensures that the door 500 remains balanced and stable during movement.

[0098] In the movement process of the hinge structure, the mounting surfaces of the mounting seat for connecting the door at any two positions are parallel. This ensures that the door 500 remains balanced and stable during movement.

[0099] In some embodiments of the present application, the distance between the first rotation axis AX1 and the third rotation axis AX3 is equal to the distance between the second rotation axis AX2 and the third rotation axis AX3. That is, the angle of rotation of the first connecting rod 110 in the counterclockwise direction is the same as the angle of rotation of the second connecting rod 120 in the clockwise direction. By keeping the distance between the first rotation axis AX1 and the third rotation axis AX3 equal to the distance between the second rotation axis AX2 and the third rotation axis AX3, a symmetrical structure is created, which can ensure that the vehicle door 500 remains balanced and stable when opening and closing, and reduces uneven stress in different positions. Due to the equal distance between the two axes, the movement of the vehicle door 500 during opening and closing is coordinated. When the vehicle door 500 is opened, the movement of each rotation point has a similar proportional change, so that the vehicle door 500 can move smoothly. In combination with the arrangement of the conical teeth, the movement of the vehicle door 500 during opening is always parallel to the initial position of the vehicle door 500.

[0100] In some embodiments of the present application, a first connecting shaft 140 and a second connecting shaft 150 are further included. The two ends of the first connecting shaft 140 are respectively connected to the second end of the first connecting rod 110 and the second end of the second connecting rod 120, i.e. the two ends of the first connecting shaft 140 are respectively connected to the first bevel gear 111 and the second bevel gear 121. The two ends of the second connecting shaft 150 are respectively connected to the first connecting shaft 140 and the third bevel gear 201. The second connecting shaft 150 is fixed relative to the first connecting shaft 140. It can be understood that the first bevel gear 111, the second bevel gear 121 and the third bevel gear 201 are respectively rotationally connected to the corresponding connecting shaft. Through the cooperation of the connecting shaft and the bevel gear, the third bevel gear 201 can be stably arranged between the first bevel gear 111 and the second bevel gear 121, and further, the vehicle door 500 can be stably connected with the hinge 100. Through the rotational connection, power can be transmitted from the hinge 100 system to the vehicle door 500, and the opening or closing movement can be completed.

[0101] On the basis of the above-mentioned embodiments, the first connecting shaft 140 and the second connecting shaft 150 are perpendicular. This helps to conduct force and at the same time ensures that the vehicle door 500 always moves in parallel.

[0102] Based on the above-mentioned hinge 100, the vertical arrangement is adopted, and the node assembly precision requirement of the hinge 100 base 300 is lower, which is convenient for processing and assembly.

[0103] In some embodiments of the present application, a driving member 400 is further provided for driving the first link 110 to rotate around the first rotation axis AX1. Optionally, the driving member 400 is a hydraulic cylinder, the cylinder body of which is hingedly connected to the vehicle body 600, and the piston rod of which is hingedly connected to the first link 110, so that the first link 110 is driven to rotate around the first rotation axis AX1 by the extension and retraction of the piston rod. The driving member 400 effectively transmits power to the hinge 100 by rotating the first link 110, thereby driving the movement of the door 500. Optionally, the cylinder body of the hydraulic cylinder is located above or below the base 300, i.e. the connection part of the hydraulic cylinder and the vehicle body 600 is spaced apart from the base 300 along the first direction D1. Optionally, the piston rod of the hydraulic cylinder is connected to the middle part of the first link 110, i.e. the connection part of the piston rod of the hydraulic cylinder and the first link 110 is located between the first rotation axis AX1 and the third rotation axis AX3, which can effectively avoid interference during the rotation of the door 500. The long stroke of the hydraulic cylinder enables the door 500 to complete a large opening degree while stably hovering at each process position, and can be directly applied to the vertical arrangement.

[0104] In some embodiments of the present application, a driving member is provided for driving the second link 120 to rotate around the second rotation axis AX2. Optionally, the driving member is a hydraulic cylinder, the cylinder body of which is hingedly connected to the vehicle body 600 or the base 300, and the piston rod of which is hingedly connected to the second link 120, so that the second link 120 is driven to rotate around the second rotation axis AX2 by the extension and retraction of the piston rod. The driving member effectively transmits power to the hinge 100 by driving the second link 120 to rotate, thereby driving the movement of the door 500.

[0105] In some embodiments of the present application, a driving member is provided for driving the sliding seat 310 to slide. The driving member effectively transmits power to the hinge 100 by driving the sliding seat 310 to slide along the sliding groove 320, thereby driving the movement of the door 500. Optionally, the driving member is a hydraulic cylinder, a pneumatic cylinder, a linear motor or other mechanisms capable of providing linear driving force, which drives the sliding seat 310 to move linearly to drive the second link 120 to rotate around the second rotation axis AX2.

[0106] In some embodiments of the present application, a third connecting rod 130 is further provided, a first end of the third connecting rod 130 is rotatably connected to the base 300 about the first rotation axis AX1, and a second end of the third connecting rod 130 is rotatably connected to the second connecting rod 120 about the third rotation axis AX3. It can be understood that the third connecting rod 130 rotates synchronously with the first connecting rod 110, and the motion trajectory thereof is similar. Optionally, a connecting piece is provided between the first connecting rod 110 and the third connecting rod 130. Optionally, the connecting piece is a rotating shaft connected between the first connecting rod 110 and the third connecting rod 130. Optionally, the driving member 400 is a hydraulic cylinder, one end of the hydraulic cylinder is adapted to be connected to the vehicle body, and the other end of the hydraulic cylinder is adapted to be connected to the connecting piece. In the direction parallel to the first rotation axis AX1, the connecting position of the hydraulic cylinder and the connecting piece is located between the first connecting rod 110 and the second connecting rod 120. By connecting the driving member 400 to the first connecting rod 110 and the third connecting rod 130, the non-rotational direction load during driving the first connecting rod 110 and the third connecting rod 130 by the driving member 400 is reduced, and the structural stability is enhanced; the driving member 400 and the first connecting rod 110 and the third connecting rod 130 are arranged in a staggered manner, and the design space of the hinge 100 of the vehicle door 500 is fully utilized. Optionally, the first connecting rod 110 and the third connecting rod 130 are integrally provided.

[0107] On the basis of the above-mentioned embodiments, the second connecting rod 120 is located between the first connecting rod 110 and the third connecting rod 130. That is, the first connecting rod 110 and the third connecting rod 130 form a clamping to the second connecting rod 120, and the clamping mechanism can increase the stability and rigidity of the hinge 100 system, and ensure that there is no excessive displacement or relative movement between the components of the hinge 100. It can be understood that the driving member 400 and the first connecting rod 110, the second connecting rod 120, and the third connecting rod 130 are arranged in a staggered manner, thereby saving space.

[0108] The present application also provides a vehicle door structure comprising the hinge structure described above. The mounting seat 200 is connected to the vehicle door 500. The vehicle door structure has the technical effects described in the above-mentioned embodiments.

[0109] Reference Figures 7 to 8 , the third aspect of the present application provides a vehicle comprising a vehicle body 600, a vehicle door 500, and the hinge structure described above. The base 300 and the sliding seat 310 are connected to the vehicle body 600, and the mounting seat 200 is connected to the vehicle door 500.

[0110] During the closing to opening process of the vehicle door 500, the first connecting rod 110 rotates by 70°, and the transmission ratio between the third bevel gear 201 and the first bevel gear 111 is 9:7, corresponding to the mounting seat 200 driving the vehicle door 500 to rotate by 90 degrees. As Figure 8 shown, at the limit position of opening the door, the first connecting rod 110 and the second connecting rod 120 have a 30° angle, which ensures that the mechanism trajectory is unique and prevents interference of the structure.

[0111] In some embodiments of the present application, a sliding groove 320 is arranged on the vehicle body 600 and is in sliding connection with the sliding seat 310. The sliding groove 320 can provide positioning and guiding functions, ensuring that the sliding seat 310 moves on a specific track, which helps to keep the vehicle door 500 open and close on the correct track, avoiding deviation or misalignment.

[0112] In some embodiments of the present application, as shown in Figure 7 When the vehicle door 500 is in the closed state, the first connecting rod 110 forms an angle of 3°-7° with the vertical direction. Preferably, the first connecting rod 110 is inclined at an angle of 5° to the outside of the vehicle body 600. This facilitates sufficient installation space for the driving member 400 between the first connecting rod 110 and the sliding groove 320, and ensures sufficient space for the force arm of the closed vehicle door 500 at the moment of opening, which facilitates the adaptation of the driving member 400 to different driving forces and lengths.

[0113] In some embodiments of the present application, the mounting seat 200 is mounted on the bottom side of the vehicle door 500.
