[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] Please see Figure 1-5 This utility model provides a three-dimensional adjustable concealed hinge (hereinafter referred to as hinge), including a fixed base 100, a rotating base 200 and a hinge assembly 300. The hinge assembly 300 is connected between the fixed base 100 and the rotating base 200. The fixed base 100 is used to connect with a door frame or a fixed device, and the rotating base 200 is used to connect with a door panel or a rotating device.

[0035] Please see Figure 2 The hinge includes a height adjustment component 400 and a front-to-back adjustment component 500. The height adjustment component 400 is used to adjust the vertical relative position between the rotating base 200 and the fixed base 100, and the front-to-back adjustment component 500 is used to adjust the front-to-back relative position between the rotating base 200 and the fixed base 100. The hinge also includes a left-to-right adjustment component 900, which is used to adjust the left-to-right relative position between the rotating base 200 and the fixed base 100.

[0036] Please see Figure 2 and Figure 5 Specifically, for height adjustment: by rotating the height adjustment screw CC mounted on the fixed base 100 via the height adjustment component 400, the lifting block (not shown in the attached diagram) connected to the rotating base 200 moves along the height direction, further driving the moving block 200 to move up and down, thus achieving height adjustment. During the adjustment process, the wear-resistant coating between the height adjustment screw and the lifting block reduces friction, making the adjustment smoother, while the POM pad 800 prevents noise generated during adjustment. Of course, the method by which the height adjustment screw drives the moving block is a mature design, so it will not be elaborated further.

[0037] Please continue reading. Figure 5 Specifically, the adjustment in the front-to-back direction is achieved by using the front-to-back adjustment assembly 500. For example, rotating the BB screw causes the front-to-back adjustment screw and the adapter nut (not shown in the attached diagram) in the front-to-back adjustment assembly 500 to rotate, further displacing the rotating seat 200 in the front-to-back direction. This adjusts the front-to-back distance between the rotating seat 200 and the fixed seat 100, ensuring the uniformity of the door gap. The method by which the front-to-back adjustment screw and the adapter nut rotate is a well-established design and will not be elaborated upon further.

[0038] Specifically, for left and right adjustments: using the left and right adjustment component 900, for example, by turning the AA screw with a hex key, the left and right adjustment screw and adjustment block (not shown in the attached diagram) in the left and right adjustment component 900 are activated, further moving the rotating seat 200 in the left and right direction, thereby adjusting the left and right position of the door panel and ensuring that the door panel is aligned with the door frame to meet usage requirements. Of course, how the left and right adjustment screw and adjustment block operate is a mature design, so it will not be described in detail.

[0039] Please continue reading. Figure 1 and Figure 2Based on the above design, the hinge also includes multiple hidden cover plates 600, which are respectively mounted on the fixed base 100 and the rotating base 200. When adjustment is required, the hidden cover plates 600 can be removed to expose the adjustment components. After adjustment, the hidden cover plates are reinstalled to restore their aesthetics and protective function. The removal and installation of the hidden cover plates are simple and convenient, and their tight-fitting design effectively prevents dust and debris from entering the hinge, further protecting the hinge components and extending their service life.

[0040] Please see Figure 2 and Figure 4 Based on the above scheme, the contact surfaces of the fixed seat 100 and the rotating seat 200, as well as the moving parts of the adjusting assembly, are all provided with a wear-resistant coating (not shown in the attached diagram). This wear-resistant coating is made of high-performance wear-resistant materials, which can effectively reduce friction and wear between components and extend the service life of the hinge. A diamond-like carbon (DLC) coating is used, which has high hardness, low coefficient of friction, and good wear resistance. Even during long-term and frequent use, it can maintain the normal operation of the hinge and reduce component failure and noise generation caused by wear.

[0041] Based on the above solution, a POM pad 800 is provided between the rotating seat 200 and the fixed seat 100, as well as in the moving parts of the adjusting assembly. The POM pad 800 can buffer the collision and friction between components, reducing noise generation. The slide groove can play a role in shock absorption and buffering when the components move, reducing noise caused by rigid collisions between components, making the hinge quieter during use and improving user comfort.

[0042] Please continue reading. Figure 3 and Figure 4 Stress grooves 700 are provided on both the fixed seat 100 and the rotating seat 200 near the hinge assembly 300. The stress grooves 700 can play a role in shock absorption and buffering when the components move, reducing the noise generated by rigid collisions between components, making the hinge quieter during use and improving user comfort.

[0043] In the above solution, the hinge exhibits excellent wear resistance: by applying a high-performance wear-resistant coating to key areas, friction and wear between components are significantly reduced, extending the hinge's lifespan and lowering maintenance costs; quiet operation: the POM pad effectively buffers collisions and friction between components, significantly reducing noise generated during hinge use and providing users with a quiet and comfortable environment; small and aesthetically pleasing door gap: the optimized structural design allows the door gap between the door panel and frame to be controlled within a very small and uniform range, enhancing the overall aesthetics of the door and meeting the high aesthetic requirements of modern architecture and furniture; compact and simple: the ingenious structural design makes the hinge small in size and occupies little space, suitable for installation on doors of various sizes and types, especially advantageous in situations with limited space; excellent concealment: the unique design of the concealed cover hides the adjustment components and other structures, resulting in an aesthetically pleasing appearance that blends seamlessly with the door frame, enhancing the overall beauty of the door while preventing dust and debris from entering, further improving the hinge's performance and lifespan.
