[0018]1. Using rollers, the device connects the hinged door component and the hinged body component to the door and body respectively through mounting holes. Rotating the door causes the hinged door component to rotate, which in turn rotates the limiting component, which in turn rotates the roller. The roller slides along the circumferential side of the limiting shaft. When the roller is embedded in a groove on the limiting shaft, it provides frictional resistance, requiring considerable force to rotate the door to dislodge the roller from the groove. This restricts the door to that position, creating a specific opening position. This allows the device to maintain a specific angle without external force when opening the door, improving its convenience. The connection and limiting functions are integrated through the connecting and limiting components. Furthermore, the limiting function created by the roller and groove in this patented device differs from the steel ball used in patent CN216008167U in that the roller and limiting shaft provide a more effective limiting function. With a larger contact area and the rollers and limiting shafts arranged in the same direction as the through holes in the door components, the device provides stable friction and better durability when the door rotates. Lubricating oil is applied to the limiting shafts, and the sealing rings at both ends of the limiting shafts provide a sealing effect to prevent lubricating oil leakage. Rotating the threaded pin compresses the spring, thus adjusting the force on the rollers. This allows the device to adjust the magnitude of the limiting push-pull force by adjusting the threaded pin. Because the limiting components are completely enclosed, this patented device is not affected by moisture and dust in the environment, which helps to optimize the durability of the limiting components and the torque decay level after durability, maintaining the stability of the device's operation. Furthermore, the processing technology and positioning techniques of the parts in this patented device are simple, and the disassembly and assembly are convenient and stable. The door and body parts can use cast aluminum materials, which are lighter than traditional forgings, achieving lightweight parts.

Technical Field
[0001] This utility model relates to the field of integrated automotive hinge technology, specifically an integrated automotive hinge with a limiting function. Background Technology
[0002] A hinge is a mechanical device used to connect two solids and allow them to move relative to each other. It is mainly used for connecting parts such as car doors, engine hoods, trunk lids, and fuel tank caps. A limit switch is a part that can fix parts such as car doors at one or more specific angles. Hinges and limit switches often work together.
[0003] A search revealed a utility model patent with application number 202323399674.7 entitled "Car Door Hinge Structure".

[0017] Compared with the prior art, this utility model provides an integrated automotive hinge with a limiting function, which has the following advantages:
[0018] 1. Using rollers, the device connects the hinged door component and the hinged body component to the door and body respectively through mounting holes. Rotating the door causes the hinged door component to rotate, which in turn rotates the limiting component, which in turn rotates the roller. The roller slides along the circumferential side of the limiting shaft. When the roller is embedded in a groove on the limiting shaft, it provides frictional resistance, requiring considerable force to rotate the door to dislodge the roller from the groove. This restricts the door to that position, creating a specific opening position. This allows the device to maintain a specific angle without external force when opening the door, improving its convenience. The connection and limiting functions are integrated through the connecting and limiting components. Furthermore, the limiting function created by the roller and groove in this patented device differs from the steel ball used in patent CN216008167U in that the roller and limiting shaft provide a more effective limiting function. With a larger contact area and the rollers and limiting shafts arranged in the same direction as the through holes in the door components, the device provides stable friction and better durability when the door rotates. Lubricating oil is applied to the limiting shafts, and the sealing rings at both ends of the limiting shafts provide a sealing effect to prevent lubricating oil leakage. Rotating the threaded pin compresses the spring, thus adjusting the force on the rollers. This allows the device to adjust the magnitude of the limiting push-pull force by adjusting the threaded pin. Because the limiting components are completely enclosed, this patented device is not affected by moisture and dust in the environment, which helps to optimize the durability of the limiting components and the torque decay level after durability, maintaining the stability of the device's operation. Furthermore, the processing technology and positioning techniques of the parts in this patented device are simple, and the disassembly and assembly are convenient and stable. The door and body parts can use cast aluminum materials, which are lighter than traditional forgings, achieving lightweight parts.
[0019] 2. Through the external bracket, the device provides greater friction and load-bearing capacity by setting two sets of limiting components, which in turn allow the two sets of rollers and limiting shafts to provide greater friction and load-bearing capacity, thereby further improving the stability of the device. Furthermore, the external bracket connects the hinge door component and the hinge body component, and provides auxiliary support to the door during the opening and closing process, making it easier for the door to open to a greater angle.
[0020] 3. By using the sleeve, the device places the sealing ring on the outside of the limiting shaft, which helps to further reduce the risk of grease leakage. Compared with placing the sealing ring directly on the limiting shaft to provide a sealing effect, placing the sealing ring on the sleeve can shorten the overall size of the device, which is conducive to providing connection and limiting functions in a smaller space, and makes the device easy to apply in small and light-load environments.

Detailed Implementation
[0027] Example 1, referring to Figure 1 An integrated automotive hinge with a limiting function includes a hinge door component 1 and a hinge body component 9. A connecting component is provided between the hinge door component 1 and the hinge body component 9. A limiting component is provided on the side of the hinge door component 1. A through hole aligned with the connecting component is provided between the top and bottom of the hinge door component 1. The hinge door component 1 and the hinge body component 9 are connected to each other through the connecting component. At least three mounting holes are provided between the two sides of the hinge door component 1 and between the two sides of the hinge body component 9.
[0028] In this utility model, the connecting component includes a limiting shaft 11 disposed inside the through hole, and the circumferential side of the limiting shaft 11 is uniformly provided with grooves. The limiting component includes a side hole 28 disposed on the side of the hinge door component 1 and communicating with the through hole.
[0029] A threaded pin 3 is threadedly connected to the inner wall of the circumferential side of the side hole 28. One end of the threaded pin 3 is detachably connected to a compression spring 4, and the other end of the compression spring 4 is detachably connected to a washer 5. The circumferential side of the washer 5 is slidably connected to the inner wall of the circumferential side of the side hole.
[0030] The circumferential side of the gasket 5 is slidably connected to the limiter bracket 6. The other end of the limiter bracket 6 is provided with a groove 2 aligned with the groove. The inner wall of the circumferential side of the groove 2 is rotatably connected to a roller 8. The other end of the roller 8 abuts against the circumferential side of the limiter shaft 11. The circumferential side of the limiter bracket 6 is detachably connected to a sealing ring 7.
[0031] Working principle: The device connects the hinged door component 1 and the hinged body component 9 to the door and body respectively through mounting holes. When the door is rotated, the hinged door component 1 rotates, which in turn rotates the limiting component. The limiting component then rotates the roller 8, which slides along the circumferential side of the limiting shaft 11. When the roller 8 is inserted into the groove on the limiting shaft 11, it provides a certain frictional resistance. A relatively large force is required to rotate the door to dislodge the roller 8 from the groove, thus restricting the door to that position and forming a specific opening position. This allows the device to maintain a specific angle without external force when opening the door, improving the device's convenience. The connection and limiting functions are integrated through the connecting component and the limiting component. Furthermore, the limiting function generated by the roller 8 and the groove in this patented device is... Compared to the steel balls used in patent CN216008167U, the roller 8 has a larger contact area with the limiting shaft 11, which can provide stable friction force and better durability. Lubricating oil is applied to the limiting shaft 11, and the sealing rings 12 at both ends of the limiting shaft 11 provide a sealing effect to prevent lubricating oil leakage. Rotating the threaded pin 3 compresses the compression spring 4, thereby adjusting the force on the roller 8. This allows the device to adjust the magnitude of the limiting push-pull force by adjusting the threaded pin 3. Because the limiting component is completely enclosed in this patented device, it is beneficial to optimize the durability of the limiting component and the torque attenuation level after long-term use, maintaining the stability of the device operation. In addition, the processing technology and positioning techniques of the parts of this patented device are simple, and the disassembly and assembly are convenient and stable.
[0032] Example 2, refer to Figure 2 The integrated automotive hinge with a limiting function also includes at least two limiting components arranged side by side of the hinge door component 1, which are aligned with the limiting shaft 11, and the rollers 8 in the two limiting components are aligned with the limiting shaft 11.
[0033] This utility model also includes a linkage assembly, which includes an outer bracket 16 disposed between the hinge door component 1 and the hinge body component 9. One end of the outer bracket 16 is connected to the hinge door component 1 via a connecting assembly. The connecting assembly also includes a hinge pin 10 that is interference-fitted to the inside of the limiting shaft 11. The circumferential side of the hinge pin 10 is interference-fitted to the inside of the outer bracket 16.
[0034] A bushing 13 is detachably connected to the circumferential side of the hinge pin 10, and a sealing ring 12 is detachably connected to the circumferential side of the limiting shaft 11. A hinge pin 17 is provided between the top of the outer bracket 16 and the top of the hinge body part 9, and between the bottom of the outer bracket 16 and the bottom of the hinge body part 9. The circumferential side of the hinge pin 17 is interference-fitted to the inside of the outer bracket 16.
[0035] The circumferential side of hinge pin 2 17 is rotatably connected to the interior of hinge body part 9. Bushing 3 18 is detachably connected to the circumferential side of hinge pin 2 17. Hinge pin 3 19 is interference-fitted between the top and bottom of hinge door part 1 and between the top and bottom of hinge body part 9.
[0036] A bushing 20 is detachably connected to the circumferential side of the hinge pin 3 19. A control link 21 is rotatably connected between the circumferential sides of the two hinge pins 3 19. An exterior trim panel 15 is detachably connected to one end of the hinge door component 1. The exterior trim panel 15 and the hinge door component 1 are fixedly connected by screws 14.
[0037] Working principle: The device sets two sets of limiting components, which enable the two sets of rollers 8 and limiting shafts 11 to provide greater friction and load-bearing capacity, further improving the stability of the device. The outer bracket 16 connects the hinge door component 1 and the hinge body component 9. The outer bracket 16 provides auxiliary support to the door during the opening and closing process, making it easier for the door to open to a larger angle.
[0038] Example 3, referring to Figure 3-5 The integrated automotive hinge with a limiting function also includes a sealing component. The sealing component includes a sleeve 27 that replaces the hinge pin 10. The circumferential side of the sleeve 27 is interference-fitted to the inside of the hinge body part 9. The circumferential side of the sleeve 27 is detachably connected to a gasket 22, a gasket 3 23, and a gasket 4 26. The top and bottom of the circumferential side of the sleeve 27 are detachably connected to a sealing ring 4 25 and a sealing ring 3 24, respectively. The top of the hinge body part 9 is threadedly connected to a bolt 29, and the circumferential side of the bolt 29 is threadedly connected to the inside of the sleeve 27.
[0039] Working principle: The device uses the sleeve 27 structure to place the sealing ring 25 on the outside of the limiting shaft 11, which helps to further reduce the risk of grease leakage. Compared with setting the sealing ring directly on the limiting shaft 11 to provide a sealing effect, setting the sealing ring on the sleeve 27 can shorten the overall volume of the device, which is conducive to the device providing connection and limiting functions in a smaller space, and is convenient for the device to be applied in small and light-load environments.
