[0025] First embodiment:

[0026] A hinge connection structure, such as Figures 1 to 4 As shown, it includes a first connecting part 1 and a second connecting part 2, with an arc-shaped part 3 between the first connecting part 1 and the second connecting part 2. The first connecting part 1, the second connecting part 2 and the arc-shaped part 3 are integrally formed into an ivory shaft. The first connecting part 1 and the second connecting part 2 are respectively installed on the upper cover 5 and the rear shell 6, so that the upper cover 5 is connected to the rear shell 6 through a hinge structure. The first connecting part 1 is fixed to the upper cover 5, and the second connecting part 2 is fixed to the rotating shaft inside the rear shell 6, thereby achieving the effect of a hinge.

[0027] The arc-shaped portion 3 includes an insert 301, one end of which is connected to the first connecting portion 1, and the other end is connected to the second connecting portion 2. The arc-shaped portion 3 also includes a plastic outer shell 302 covering the insert 301. The insert 301 can retain its metal material, ensuring load-bearing strength while using the plastic outer shell 302 to replace the traditional metal surface treatment process, reducing processing difficulty and improving production efficiency. At the same time, using the plastic outer shell 302 can improve the corrosion and rust prevention effect of existing metal ivory shafts and extend their service life.

[0028] In this embodiment, the first connecting part 1, the second connecting part 2, and the insert 301 are integrally formed and made of metal. This effectively ensures the structural integrity and load-bearing strength, and can be directly cast or stamped, making production convenient.

[0029] The plastic shell 302 completely encloses the insert 301, and the plastic shell 302 has the same shape as the insert 301. Specifically, the plastic shell 302 is injection molded onto the outer surface of the insert 301. The plastic shell 302 is formed by injection molding by filling the outer surface of the insert 301. The inner wall of the plastic shell 302 is attached to the outer surface of the insert 301, thereby achieving a seal for the insert 301, providing corrosion and rust prevention, and resulting in high production efficiency.

[0030] In other embodiments, the plastic housing 302 is detachably connected to the insert 301. The plastic housing 302 includes a first body and a second body, which can be fixed by adhesive or snap-fit.

[0031] In this embodiment, the first connecting part 1, the second connecting part 2, and the arc-shaped part 3 have the same thickness. The arc-shaped part 3 includes an insert 301 and a plastic shell 302 that wraps around the insert 301. After the plastic shell 302 is injection molded, the overall thickness of the ivory shaft is consistent, which simplifies the complexity of mold development and avoids process defects such as shrinkage and deformation.

[0032] The plastic housing 302 does not require further polishing in the future. Meanwhile, the insert 301 can use a uniform template. When there is a need for color change or surface treatment of the ivory shaft, only the plastic housing 302 needs to be changed.

[0033] The first connecting part 1 and the second connecting part 2 are each provided with a fixing hole 4. Both the first connecting part 1 and the second connecting part 2 are metal plates, and the fixing holes 4 penetrate through the metal plates. The first connecting part 1 and the second connecting part 2 are installed and fixed by fasteners passing through the fixing holes 4. The fasteners can be screws, pins, rivets, bolts, etc. After the fasteners pass through the fixing holes 4, they are tightened onto the upper cover 5 or the rear shell 6 to fix the hinge connection structure. The fixing holes 4 are countersunk holes, so when the fasteners are inserted, the heads of the fasteners will not protrude from the surface of the connecting part.

[0034] The first connecting part 1 and the second connecting part 2 are each provided with at least two fixing holes 4. In this embodiment, the first connecting part 1 and the second connecting part 2 are each provided with two fixing holes 4. The two fixing holes 4 are arranged along the length direction of the metal plate. By providing two fixing holes 4, the ivory shaft can be installed and positioned to avoid displacement. At the same time, it can prevent stress fatigue caused by single-point fixing and enhance the structural reliability under long-term use.

[0035] This embodiment also provides a smart cover, such as Figure 4As shown, the smart cover includes an upper cover 5 and a rear shell 6, and also includes the hinge connection structure described in the above embodiment. The upper cover 5 is connected to the rear shell 6 through the hinge connection structure to realize the flipping function of the upper cover 5. The first connecting part 1 and the second connecting part 2 are respectively hidden inside the upper cover 5 and the rear shell 6. When the upper cover 5 is fully opened, only the arc-shaped part 3 is exposed. Therefore, the plastic shell 302 can completely cover the appearance of the arc-shaped part 3, increasing the diversity of the overall hinge structure appearance and improving the freedom of product appearance design.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
