Description

Technical Field

[0001] This utility model relates to hinge structures, and more particularly to a hinge structure for an adjustable automobile sliding door. Background Technology

[0002] The position of the hinge in a car sliding door needs to be adjusted when the door is assembled with the car body. The traditional method is to remove the hinge, adjust it, and then reinstall it, which makes the adjustment process time-consuming. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable hinge structure for a car sliding door that saves adjustment time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable hinge structure for a car sliding door, including a fixed seat, the fixed seat having a U-shaped fixed seat main body, fixed seat mounting parts being provided on both sides of the fixed seat main body, fixed seat mounting holes being provided on the fixed seat mounting parts, and an adjusting pin being provided at the fixed seat main body;

[0005] The support arm has a main body, a vertical section at one end of the main body, and two mounting ears at the vertical section: a first mounting ear on the upper side and a second mounting ear on the lower side. A guide wheel mounting section is located at the other end of the main body, and guide wheel assemblies, namely a first guide wheel, a second guide wheel, and a third guide wheel, are mounted on the guide wheel mounting section. The characteristic feature is that...

[0006] The adjusting pin is located inside the main body of the fixed base and includes an upper adjusting pin and a lower adjusting pin. The upper adjusting pin is provided with an external thread, and two mounting ears are installed on the adjusting pin. The first mounting ear is located on the upper adjusting pin, and an adjustment locking nut is provided on the upper adjusting pin below the first mounting ear. The second mounting ear is located on the lower adjusting pin.

[0007] Further: The outer diameter of the upper part of the adjusting pin is larger than that of the lower part of the adjusting pin.

[0008] Compared with the prior art, this utility model has the following advantages: By adjusting the adjusting pin (locking nut), the support arm of the middle hinge, along with the guide wheel, moves along the adjustment direction to the designated position required for the assembly of the door and the body, and then the locking nut locks in place. This utility model allows for direct and quick adjustment of the middle hinge position during installation, saving labor time. Attached Figure Description

[0010] Figure 2This is a second perspective view of the hinge structure in an adjustable car sliding door.

[0011] Figure 3 This is a third-angle perspective view of the hinge structure in an adjustable car sliding door, with the adjustment pin in cross-section. Detailed Implementation

[0012] Example 1: See Figures 1 to 3 An adjustable hinge structure for a car sliding door includes a fixed base, the fixed base having a U-shaped fixed base main body 11, fixed base mounting parts 12 respectively provided on both sides of the fixed base main body 11, fixed base mounting holes provided on the fixed base mounting parts 12, and an adjusting pin provided at the fixed base main body 11.

[0013] The support arm has a support arm main body 21. One end of the support arm main body 21 is provided with a support arm vertical part 22. Two mounting ears are provided at the support arm vertical part 22, namely a first mounting ear 231 located on the upper side and a second mounting ear 232 located on the lower side. The other end of the support arm main body 21 is provided with a guide wheel mounting part 24. A guide wheel assembly is mounted on the guide wheel mounting part 24, namely a first guide wheel 251, a second guide wheel 252 and a third guide wheel 253.

[0014] The adjusting pin is located inside the main body of the fixed base and includes an upper adjusting pin 31 and a lower adjusting pin 32. The upper adjusting pin 31 is provided with external threads, and two mounting ears are installed on the adjusting pin. The first mounting ear 231 is located on the upper adjusting pin 31, and an adjusting locking nut 41 is provided on the upper adjusting pin 31 below the first mounting ear 231. The second mounting ear 232 is located on the lower adjusting pin 32.

[0015] In this embodiment, the outer diameter of the upper part 31 of the adjusting pin is larger than that of the lower part 32 of the adjusting pin.

[0016] This invention relates to a simple and efficient adjustable hinge structure for automotive sliding doors. It is suitable for applications where the hinge guide wheel needs adjustment during the assembly of the door and the car body, based on the actual installation requirements. The fixed mounting base is installed on the door. By adjusting the adjusting pin (locking nut), the hinge support arm, carrying the guide wheel, moves along the adjustment direction to the designated position required for door and body assembly. The locking nut then locks the position (the vertical movement of the locking nut adjusts the hinge support arm vertically). This structure allows for quick and direct adjustment of the hinge position during installation, saving time.

[0017] Example 2: The basic scheme is the same as Example 1, except that a threaded connecting collar is used at the bottom of the upper part 31 of the adjusting pin to facilitate the use of the collar.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above-described embodiments. All technical solutions that fall within the principles of this utility model are within its protection scope. For those skilled in the art, any improvements made without departing from the principles of this utility model should also be considered within its protection scope.
