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

[0088] The hinge 100 provided by the present solution has an extended position and a retracted position, so that the mounting base 200 is close to or away from the base 300, and the door 500 is close to or away from the vehicle body 600. In the present application, the first connecting rod 110 and the second connecting rod 120 in the hinge 100 are arranged so that the door 500 can achieve smooth movement during the opening and closing process, avoiding unnecessary vibration or impact. The first connecting rod 110 and the second connecting rod 120 form a structure similar to a triangle, which improves the stability of the hinge 100 system, balances the load, enhances rigidity, and controls the motion path, thereby optimizing the function and performance of the entire hinge structure. Specifically, it can provide solid support during the movement of the door 500, 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 door 500 is opened or closed, which can avoid excessive force being concentrated on a certain connection point, reduce the force on the hinge 100 and related connectors, and provide more uniform support; similar triangular structures can effectively increase the stiffness of the connector and hinge 100 system, improve the deformation resistance of the entire system, and avoid unnecessary bending or twisting; by adjusting the angle between the first link 110 and the second link 120, the movement path of the door 500 can be precisely controlled, so that the door 500 can be opened and closed in a specific arc to avoid collision with other body 600 components or obstacles.

[0089] The first connecting rod 110 and the second connecting rod 120 rotate in opposite directions, so that the vehicle door 500 can rotate in a specific dimension, and can achieve precise rotation control, maintain parallel motion, improve transmission efficiency, and flexibly adjust the door opening angle.

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

[0091] During the movement of the hinge structure, the angle between the first link 110 and the second link 120 is greater than 0° and less than 180°. By limiting the angle between the first link 110 and the second link 120, the movement trajectory of the hinge structure is unique and the stability during the 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. Among them, the first bevel gear 111 and the second bevel gear 121 are both meshed 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 around the fourth rotation axis AX4. With the meshing of the bevel gears, the door 500 can be rotated in a specific dimension, and the effects of precise rotation control, maintaining parallel motion, improving transmission efficiency and flexibly adjusting the door opening angle can be achieved, thereby improving the functionality and reliability of the door 500, thereby providing a better user experience and convenience. Specifically, the meshing mechanism of the bevel gears can provide precise rotation transmission, and can accurately control the rotation angle and speed when the door 500 is opened and closed, ensuring that the movement of the door 500 is smooth, stable and controllable; through the cooperation of the bevel gears, the door 500 remains parallel to the original position during the rotation process, avoiding tilting or instability. Ensure that the door 500 always maintains a consistent positional relationship with the vehicle body 600 during the opening and closing process; the bevel gear transmission has good transmission efficiency, can effectively transmit the 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 demand for the opening angle of the door 500 in different scenarios can be met, and the adaptability and convenience can be improved. In addition, by adjusting the center distance and transmission ratio between the bevel gears, it can adapt to the adjustment of different side opening angles.

[0093] In some embodiments of the present application, in the projection of the plane where the base 300 is located, the third rotation axis AX3 is located between the first rotation axis AX1 and the second rotation axis AX2. 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 compactly arrange the hinge 100 between the door 500 and the body 600, thereby minimizing the space occupation. That is, the hinge end of the first link 110 and the second link 120 is located between the first link 110 and the second link 120, and when the door 500 is opened or closed, a stable balance is provided in the moment distribution 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 vehicle 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 spaced apart from each other along a height direction or a length direction of the vehicle body.

[0096] In some embodiments of the present application, the first rotation axis AX1 extends along the front-to-back direction of the vehicle. It is understandable that the second rotation axis AX2 extends along the front-to-back direction of the vehicle. Therefore, the hinge structure can be arranged vertically, and the assembly accuracy requirements for the hinge 100 base 300 node are relatively low, which is convenient for processing and assembly. Through the rotation arrangement 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 at the initial position are located is parallel to the mounting surface of the mounting seat 200 for connecting to the vehicle door 500. During the movement of the hinge structure, the mounting surfaces of the mounting seat 200 for connecting to the vehicle door 500 at any two positions are parallel, ensuring that the vehicle door 500 remains balanced and stable during the movement.

[0098] During the movement of the hinge structure, the mounting surfaces of the mounting seats at any two positions for connecting with the vehicle door are parallel, ensuring that the vehicle door 500 remains balanced and stable during the movement.

[0099] In some embodiments of the present application, the wheelbase between the first rotation axis AX1 and the third rotation axis AX3 is equal to the wheelbase between the second rotation axis AX2 and the third rotation axis AX3. That is, the rotation angle of the first connecting rod 110 in the counterclockwise direction is the same as the rotation angle of the second connecting rod 120 in the clockwise direction. By keeping the wheelbase between the first rotation axis AX1 and the third rotation axis AX3 equal to the wheelbase between the second rotation axis AX2 and the third rotation axis AX3, a symmetrical structure is generated, which can ensure that the door 500 remains balanced and stable when opening and closing, and reduce uneven forces at different positions. Since the two wheelbases are equal, the movement of the door 500 during the opening and closing process is coordinated. When the door 500 is opened, the movement of each rotation point has a similar proportional change, so that the door 500 can move smoothly. Combined with the setting of the conical teeth, the movement of the door 500 during the opening process is always parallel to the initial position of the 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, that is, 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 relatively fixed 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 connected to the corresponding connecting shafts. Through the cooperation of the connecting shaft and the bevel gear, the third bevel gear 201 can be stably connected between the first bevel gear 111 and the second bevel gear 121, and further, the door 500 can be stably connected to the hinge 100. Through the rotation connection, power can be transmitted from the hinge 100 system to the door 500, and the opening or closing movement is completed.

[0101] On the basis of the above embodiment, the first connecting shaft 140 is perpendicular to the second connecting shaft 150, which is helpful for force transmission and can ensure that the door 500 always moves in parallel.

[0102] Based on the above-mentioned hinge 100, a vertical arrangement is adopted, which has a lower requirement on the assembly accuracy of the nodes of the base 300 of the hinge 100, and is easy to process and assemble.

[0103] In some embodiments of the present application, a driving member 400 is further provided, and the driving member 400 is used to drive the first connecting rod 110 to rotate around the first rotation axis AX1. Optionally, the driving member 400 is a hydraulic cylinder, the cylinder body is hingedly connected to the vehicle body 600, and the piston rod is hingedly connected to the first connecting rod 110. Through the extension and contraction of the piston rod, the first connecting rod 110 is rotated around the first rotation axis AX1. The driving member 400 acts on the first connecting rod 110 through rotation, effectively transmitting power to the hinge 100, thereby driving the movement of the door 500. Optionally, the cylinder body of the hydraulic cylinder is located above or below the base 300, that is, the connection part between the hydraulic cylinder and the vehicle body 600 is spaced 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 connecting rod 110, that is, the connection part between the piston rod of the hydraulic cylinder and the first connecting rod 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 hydraulic cylinder has a long stroke, so that the door 500 can open to a large degree and can also be stably suspended at various process positions, and can be directly applied to vertical arrangement.

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

[0105] In some embodiments of the present application, a driving member is provided to drive the slide 310 to slide. The driving member drives the slide 310 to slide along the slide groove 320, effectively transmitting power to the hinge 100, thereby driving the movement of the door 500. Optionally, the driving member is a hydraulic cylinder, a pneumatic cylinder, a linear motor or other mechanism capable of providing a linear driving force, and the driving member drives the slide 310 to move in a straight line to drive the second connecting rod 120 to rotate around the second rotation axis AX2.

[0106] In some embodiments of the present application, a third connecting rod 130 is also provided, and the first end of the third connecting rod 130 is rotatably connected to the base 300 around the first rotation axis AX1, and the second end of the third connecting rod 130 is rotatably connected to the second connecting rod 120 around the third rotation axis AX3. It can be understood that the third connecting rod 130 rotates synchronously with the first connecting rod 110, and their motion trajectories are similar. Optionally, a connecting member is provided between the first connecting rod 110 and the third connecting rod 130. Optionally, the connecting member is a rotating shaft connected to 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 suitable for connection with the vehicle body, and the other end of the hydraulic cylinder is suitable for connection with the connecting member. In a direction parallel to the first rotation axis AX1, the connection position of the hydraulic cylinder and the connecting member is located between the first connecting rod 110 and the second connecting rod 120. By connecting the driving member 400 between the first link 110 and the third link 130, the non-rotational load during the movement of the first link 110 and the third link 130 driven by the driving member 400 is reduced, and the structural stability is enhanced; the driving member 400 and the first link 110 and the third link 130 are staggered, making full use of the design space of the hinge 100 of the vehicle door 500. Optionally, the first link 110 and the third link 130 are integrally arranged.

[0107] On the basis of the above embodiment, 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 clamp for the second connecting rod 120, and the clamping mechanism can increase the stability and rigidity of the hinge 100 system, ensuring that there will be 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 staggered to save space.

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

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

[0110] When the door 500 is opened from closed, the first connecting rod 110 rotates 70 degrees, the transmission ratio between the third bevel gear 201 and the first bevel gear 111 is 9:7, and the corresponding mounting seat 200 drives the door 500 to rotate 90 degrees. Figure 8 As shown, when the door is in the extreme opening position, there is an angle of 30° between the first connecting rod 110 and the second connecting rod 120, which ensures the uniqueness of the mechanism trajectory and prevents structural interference.

[0111] In some embodiments of the present application, a slide groove 320 is provided on the vehicle body 600, and the slide groove 320 is slidably connected to the slide seat 310. The slide groove 320 can provide positioning and guiding functions, ensuring that the slide seat 310 moves on a specific track, and helps to keep the door 500 opened and closed on the correct track to avoid deviation or misalignment.

[0112] In some embodiments of the present application, Figure 7 As shown, when the vehicle door 500 is in the closed state, the angle between the first connecting rod 110 and the vertical direction is 3°-7°. Preferably, the first connecting rod 110 and the outer side of the vehicle body 600 have an inclination angle of 5°.
