Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to an automotive side door hinge. Background Technology

[0002] As a key connecting component enabling the flexible opening and closing of side doors, the side door hinge directly affects the ease of operation and driving safety of the vehicle door. Currently, common side door hinges mainly consist of hinge plates (body parts and door parts), hinge pins, screws, washers, and bushings. Their working principle is based on the relative rotation between the pin and the hinge plate, which enables the side door to rotate around a fixed axis.

[0003] Riveting technology is a key step in hinge manufacturing. In terms of riveting process, traditional hinge pins and washers often use a ring or circular mating surface design, which can easily lead to insufficient riveting strength in side door hinges, affecting their use. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive side door hinge that solves the problem that traditional hinge pins and washers often use annular and circular mating surfaces, which can easily lead to insufficient riveting strength of the side door hinge and affect its use.

[0005] To achieve the above objectives, this utility model employs an automotive side door hinge, comprising a body component, a screw, a hinge pin, a bushing, a hexagonal washer, and a door component. The screw is movably connected to the body component and passes through it. The door component is located on one side of the body component. The bushing is movably connected to the door component and is located inside it. The hinge pin is movably connected to the bushing and is located inside it. The end of the hinge pin has a hexagonal face, and the hexagonal washer has a hexagonal inner hole. The hexagonal washer is fitted onto the hexagonal face of the hinge pin.

[0006] The car side door hinge also includes a guide head, which is fixedly connected to the screw and located at the end of the screw.

[0007] The vehicle body component has a first inner arc surface, the end of the hinge pin is in contact with the first inner arc surface, and the door component has a second inner arc surface.

[0008] The bushing has a bevel, which is used for the bushing to enter the door component.

[0009] This utility model discloses an automotive side door hinge. In use, the holes in the door component are first aligned with the holes in the body component. Then, the bushing is placed in the hole of the door component. Next, a hexagonal washer is fitted onto the end of the hinge pin, where the hexagonal face of the hinge pin precisely engages with the hexagonal inner hole of the hexagonal washer. The hinge pin is then passed through the door component and into the hole of the body component. Finally, the screw is connected to the hinge pin, completing the hinge installation. In this method, the precise engagement between the hexagonal face of the hinge pin and the hexagonal inner hole of the hexagonal washer restricts the axial flow of material under the action of the push-out force, enhancing the riveting structure's resistance to separation and loosening, fundamentally improving the riveting strength. This improves the riveting strength of the side door hinge and facilitates its use. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figures 1-4 This utility model provides an automotive side door hinge: including a body part 101, a screw 102, a hinge pin 103, a bushing 104, a hexagonal washer 105, and a door part 106. The screw 102 is movably connected to the body part 101 and passes through the body part 101. The door part 106 is located on one side of the body part 101. The bushing 104 is movably connected to the door part 106 and is located inside the door part 106. The hinge pin 103 is movably connected to the bushing 104 and is located inside the bushing 104. The end of the hinge pin 103 has a hexagonal surface 107. The hexagonal washer 105 has a hexagonal inner hole 108 and is sleeved on the hexagonal surface 107 of the hinge pin 103.

[0018] In this embodiment, during use, the hole in the door component 106 is first aligned with the hole in the body component 101. Then, the bushing 104 is placed in the hole in the door component 106. Next, the hexagonal washer 105 is fitted onto the end of the hinge pin 103, wherein the hexagonal surface 107 of the hinge pin 103 and the hexagonal inner hole 108 of the hexagonal washer 105 form a precise fit. Then, the hinge pin 103 is passed through the door component 106 and into the body component. Finally, the screw 102 is connected to the hinge pin 103 in the hole 101 to complete the installation of the hinge. In the above method, the hexagonal surface 107 of the hinge pin 103 and the hexagonal inner hole 108 of the hexagonal washer 105 form a precise fit, which restricts the axial flow tendency of the material in the hinge pin 103 under the action of the push-out force, enhances the anti-separation and anti-loosening ability of the riveting structure, fundamentally improves the riveting strength, and realizes the ability to improve the riveting strength of the side door hinge, which is beneficial to use.
