Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] The hinge and vehicle provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0030] In existing technologies, to meet the aesthetic requirements of new hinge designs while preventing users from bumping their heads when the tailgate is open, the opening angle of the tailgate generally needs to be increased to over 90°. Traditional stamped hinges can meet the aesthetic requirements of new designs, but they cannot meet the requirements for large opening angles. While steel hinges can meet the requirements for large opening angles, the connection between the steel hinge and the vehicle body is a single point, resulting in low connection strength. This makes the tailgate prone to detaching from the vehicle body, thus affecting the overall lifespan of the vehicle. Therefore, there is an urgent need for a hinge that can meet both the requirements for large opening angles and the requirements for connection strength with the vehicle body.

[0031] like Figures 1 to 5 As shown in the embodiment of this application, a hinge is proposed, including: a fixing member 10, a rotating member 20, and at least two fasteners 30; the fixing member 10 includes a fixing part 11 and a first connecting part 12, the first connecting part 12 is disposed on one side of the fixing part 11 and connected to the fixing part 11, the rotating member 20 is rotatably connected to the first connecting part 12, the rotating member 20 has a rotation axis, and the rotating member 20 can rotate relative to the first connecting part 12 about the rotation axis; the extension direction of the rotation axis is a first direction X, the fixing part 11 extends along the first direction X, and at least two fasteners 30 are spaced apart along the first direction X, the fasteners 30 pass through the fixing part 11 and are adapted to be connected to the vehicle body.

[0032] It should be noted that, as Figures 1 to 5 As shown, the rotation axis of the rotating component 20 is the axis of the pin 40, the extension direction of the rotation axis is the axial direction of the pin 40, and the first direction X is the axial direction of the pin 40.

[0033] In this embodiment, by placing the first connecting part 12 on one side of the fixed part 11 and connecting it to the fixed part 11, the rotating member 20 is rotatably connected to the first connecting part 12, and the rotating member 20 can rotate relative to the first connecting part 12 around the rotation axis; the rotating member 20 is connected to the tailgate, the fixed part 11 extends along the first direction X, and at least two fasteners 30 are spaced apart along the first direction X, passing through the fixed part 11 and connecting to the vehicle body. Thus, the robust connection between the fixed member 10 and the vehicle body, and the rotatable connection between the rotating member 20 and the fixed member 10, ensure the stability of the hinge under stress; furthermore, by providing at least two fasteners 30 to connect the fixed member 10 and the vehicle body, the connection strength between the fixed member 10 and the vehicle body is enhanced, thereby ensuring a stable connection between the tailgate and the vehicle body and preventing the tailgate from detaching from the vehicle body.

[0034] Furthermore, the multiple fasteners 30 are distributed along the first direction X, which can effectively disperse the load between the fixing member 10 and the vehicle body, avoid local stress concentration, and thus improve the connection strength and reliability. The axial direction of the rotating shaft is consistent with the extension direction of the fixing part 11, so that the rotating member 20 is subjected to uniform force during rotation, reducing vibration and noise during movement and improving the user experience.

[0035] In practical applications, the rotating part 20 can also be connected to the vehicle's doors, engine hood, fuel tank cap, and other components, while the fixing part 10 is fixed at the corresponding position on the vehicle body.

[0036] In some embodiments, the hinge may be made of aluminum alloy or high-strength steel; the hinge may be manufactured using a forging process to ensure the density and uniformity of the material and improve its fatigue resistance.

[0037] In some embodiments, the first connecting portion 12 and the fixing portion 11 are generally L-shaped to increase the rigidity and stability of the fixing member 10, thereby improving the durability and reliability of the entire structure.

[0038] Optionally, such as Figure 2 and Figure 5 As shown, the dimension of the fixed part 11 along the first direction X is A, and the dimension of the rotating part 20 along the first direction X is B, satisfying: 0.9≤A / B≤1.1.

[0039] In this embodiment, the ratio of the dimension A of the fixed part 11 along the first direction X to the dimension B of the rotating part 20 along the first direction X is set within a certain range. This proportional relationship ensures good matching between the fixed part 11 and the rotating part 20 in the length direction, guaranteeing structural coordination between them and avoiding uneven stress or structural imbalance caused by excessive dimensional differences, thereby improving the overall structural stability.

[0040] Preferred option: A / B = 1. This allows the fixed part 11 and the rotating part 20 to distribute the load more evenly when under stress, thereby helping to reduce local stress concentration and avoiding the risk of fatigue or breakage caused by excessive stress on a certain part, thus improving the load-bearing capacity and service life of the hinge.

[0041] For example, the value of A / B can be set to any value among 0.9, 0.95, 1.0, 1.05, and 1.1, as well as any range between any two values.

[0042] Optionally, such as Figure 2 and Figure 5 As shown, the end where the first connecting part 12 is connected to the fixing part 11 is the first end 13; the dimension of the first end 13 along the first direction X is C, which satisfies: C≤A.

[0043] It should be noted that, as Figure 2 and Figure 5 As shown, a transition portion 15 is provided between the first connecting portion 12 and the fixing portion 11. The transition portion 15 is arranged in an arc shape. A dividing line 16 is provided between the transition portion 15 and the first connecting portion 12. The first end 13 refers to the end where the dividing line 16 is located. That is, the dimension C of the first end 13 along the first direction X is the length of the dividing line 16.

[0044] Specifically, the method for measuring the dimension C of the first end 13 along the first direction X includes: aligning the measuring head of the measuring tool with the starting point of the dividing line 16; extending the measuring tool along the first direction X to measure the ending point of the dividing line 16; and reading the measured value, which is the value of dimension C. The measuring tool may include a vernier caliper, a tape measure, or a micrometer, and those skilled in the art can select the appropriate measuring tool according to actual needs.

[0045] In this embodiment, the dimension C of the first end 13 along the first direction X is set to be less than or equal to the dimension A of the fixing part 11 along the first direction X. This ensures that the first connecting part 12 does not exceed the size range of the fixing part 11 at the connection point, making the force on the fixing part 11 and the first connecting part 12 at the connection point more uniform, avoiding structural imbalance or uneven force due to size mismatch, thereby improving the stability of the overall structure.

[0046] In some embodiments, such as Figure 2 As shown, the dimension C of the first end 13 along the first direction X is smaller than the dimension A of the fixing part 11 along the first direction X. In this way, the amount of material used in the first end 13 can be reduced, thereby reducing costs.

[0047] In other embodiments, such as Figure 3 and Figure 5 As shown, the dimension C of the first end 13 along the first direction X is equal to the dimension A of the fixed part 11 along the first direction X. In this way, when the fixed part 11 is subjected to load, the load is distributed more evenly between the fixed part 11 and the first connecting part 12, avoiding the problem of local stress concentration caused by abrupt changes in the force-bearing area, thereby avoiding the risk of fatigue or fracture due to excessive force on a certain part, and improving the load-bearing capacity and service life of the hinge.

[0048] It should be noted that, Figure 3 and Figure 1 Except for the structure and size of the connecting parts, the rest of the structures are the same.

[0049] Optionally, such as Figure 2 and Figure 5 As shown, the first connecting part 12 also has a second end 14 disposed opposite to the first end 13, and the second end 14 is rotatably connected to the rotating member 20; the dimension of the second end 14 along the first direction X is D, which satisfies: D < C.

[0050] It should be noted that the second end 14 refers to the part where the first connecting part 12 and the rotating member 20 are connected and overlap. The dimension of the second end 14 along the first direction X is the same as the measurement direction of the first end 13, which will not be described again in this application.

[0051] In this embodiment, the second end 14 is rotatably connected to the rotating member 20, and the dimension of the second end 14 along the first direction X is set to be smaller than the dimension C of the first end 13 along the first direction X. This reduces the overall material usage of the first connecting part 12, thereby lowering costs. In addition, this design makes the assembly process more flexible and convenient, better adaptable to different vehicle body structures and installation requirements, and improves assembly efficiency.

[0052] In some embodiments, the dimension of the first connecting portion 12 along the first direction X can be gradually reduced or reduced in stages; this application does not impose such limitations.

[0053] Optionally, such as Figures 1 to 3As shown, it also includes a pin 40; the rotating member 20 has two second connecting parts 21 at one end facing the first connecting part 12, and the two second connecting parts 21 are spaced apart along the first direction X; a first rotation space is formed between the two second connecting parts 21, and the second end 14 extends into the first rotation space; the pin 40 passes through the first connecting part 12 and the second connecting part 21, and the rotating member 20 can rotate relative to the pin 40 around the rotation axis, and the axis of the pin 40 is the rotation axis.

[0054] In this embodiment, two second connecting portions 21 are provided at one end of the rotating member 20 facing the first connecting portion 12, and the two second connecting portions 21 are spaced apart along the first direction X, forming a first rotation space between the two second connecting portions 21. The second end 14 extends into the first rotation space. The axis of the pin 40 is the rotation axis, and the pin 40 passes through the first connecting portion 12 and the second connecting portion 21, so that the rotating member 20 can rotate relative to the pin 40. In this way, the pin 40 can be used as an intermediate connecting member to connect the first connecting portion 12 and the second connecting portion 21, thereby effectively transmitting and distributing the load, reducing stress concentration caused by direct connection, and thus improving the stability and durability of the overall structure.

[0055] Furthermore, by setting two second connecting parts 21 spaced apart along the first direction X, the load can be better distributed, reducing the possibility of excessive force at a single point, thereby improving the durability and reliability of the overall structure. Simultaneously, a first rotational space is formed between the two second connecting parts 21, and the second end 14 of the first connecting part 12 extends into the first rotational space, providing greater rotational freedom and flexibility for the rotating component 20, reducing motion interference, and improving the smoothness of the rotation of the rotating component 20.

[0056] In some embodiments, the rotating member 20 further includes a third connecting portion 22, which is fixedly connected to two second connecting portions 21 and connected to the rear door.

[0057] Optionally, such as Figures 4 to 5 As shown, it also includes a pin 40; the first connecting part 12 is provided with two connecting segments 121 at positions corresponding to the second connecting part 21, and the two connecting segments 121 are spaced apart along the first direction X; a second rotation space is formed between the two connecting segments 121, the second connecting part 21 extends into the second rotation space, the pin 40 passes through the first connecting part 12 and the second connecting part 21, the rotating part 20 is rotatably connected to the fixed part 10 through the pin 40, and the axis of the pin 40 is the rotation axis.

[0058] In this embodiment, two connecting segments 121 are provided at corresponding positions of the first connecting portion 12 and the second connecting portion 21, and the two connecting segments 121 are spaced apart along the first direction X. A second rotation space is formed between the two connecting segments 121, and the second connecting portion 21 extends into the second rotation space. A pin 40 passes through the first connecting portion 12 and the second connecting portion 21, and the rotating member 20 is rotatably connected to the fixed member 10 through the pin 40, with the axis of the pin 40 being the axis of rotation. This provides greater rotational freedom and flexibility for the rotating member 20, thereby reducing motion interference and improving the smoothness of rotation.

[0059] In some embodiments, such as Figure 4 and Figure 5 As shown, the second connecting part 21 can be set to two, which is beneficial to improve the connection stability between the second connecting part 21 and the first connecting part 12; of course, the second connecting part 21 can also be set to one, and this embodiment of the application does not limit it.

[0060] Optionally, such as Figure 2 and Figure 5 As shown, it also includes a bushing 50; the first connecting part 12 is provided with a first mounting hole, the bushing 50 is disposed in the first mounting hole, and the pin 40 passes through the bushing 50 and is rotatably connected to the bushing 50.

[0061] In this embodiment, the bushing 50 is disposed in the first mounting hole, and the pin 40 passes through the bushing 50 and is rotatably connected to the bushing 50. This reduces friction, wear, vibration, and abnormal noise between the pin 40 and the first mounting hole, thereby improving the smoothness and durability of the pin 40's rotation.

[0062] In some embodiments, the bushing 50 may be made of a wear-resistant material (such as nylon, polyoxymethylene, etc.) to provide good lubrication when the pin 40 rotates.

[0063] In some embodiments, such as Figure 2 As shown, if a first mounting hole is provided in the first connecting part 12, the bushing 50 can also be provided as one; as Figure 5 As shown, when the first connecting part 12 has two first mounting holes, the bushing 50 can also be provided as two.

[0064] Optionally, such as Figure 1 and Figure 3 As shown, the first connecting part 12 has a clearance space 60 at a position corresponding to the second connecting part 21, and a portion of the second connecting part 21 is disposed in the clearance space 60.

[0065] In this embodiment, a clearance space 60 is provided at a position corresponding to the second connecting part 21, and a portion of the second connecting part 21 is disposed within the clearance space 60. This allows the second connecting part 21 to rotate within a certain range, thereby improving the flexibility and adaptability of the overall structure. Furthermore, by providing the clearance space 60, interference problems that may occur between the first connecting part 12 and the second connecting part 21 during movement are reduced, and collisions or jamming caused by overlapping movement paths are avoided, thereby improving the smoothness and reliability of movement.

[0066] Optionally, such as Figures 1 to 5 As shown, fastener 30 is a press-fit bolt, which is riveted to fixing part 11.

[0067] In this embodiment, the press-fit bolts are fixed by riveting, forming a mechanical interlock that provides a stable connection, prevents loosening, and thus improves structural stability. Furthermore, the installation process of press-fit bolts is quick and suitable for automated production, reducing assembly time and improving production efficiency.

[0068] Optionally, such as Figures 1 to 5 As shown, the fixing part 11 and the first connecting part 12 are integrally formed parts.

[0069] In this embodiment, the fixing part 11 and the first connecting part 12 are integrally formed. This makes the fixing part 11 and the first connecting part 12 more compact and integrated in structure, avoiding problems such as insufficient strength or stress concentration at the connection point that may be caused by a split design, thereby improving the stability and reliability of the overall structure.

[0070] Furthermore, the unibody design reduces the number of parts and assembly complexity, thereby lowering manufacturing costs. At the same time, by reducing potential failure points at joints, the overall structure is more reliable, reducing later maintenance and repair costs.

[0071] Optionally, embodiments of this application provide a vehicle including the hinge as described in the above embodiments.

[0072] In this embodiment, the first connecting part 12 is disposed on one side of the fixed part 11 and connected to the fixed part 11. The rotating member 20 is rotatably connected to the first connecting part 12 and can rotate relative to the first connecting part 12. The rotating member 20 is connected to the tailgate. The fixed part 11 extends along the first direction X, and at least two fasteners 30 are spaced apart along the first direction X. The at least two fasteners 30 pass through the fixed part 11 and are connected to the vehicle body. In this way, the stability of the hinge under force is ensured by the firm connection between the fixed member 10 and the vehicle body, and the rotatable connection between the rotating member 20 and the fixed member 10. Furthermore, by providing at least two fasteners 30 to connect the fixed member 10 and the vehicle body, the connection between the fixed member 10 and the vehicle body can be strengthened, thereby ensuring a stable connection between the tailgate and the vehicle body and preventing the tailgate from falling off the vehicle body.
