[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. Existing hinges have a relatively large overall thickness. To ensure their effectiveness, grooves need to be cut into the solid objects during installation. The hinge is installed in the grooves during assembly, which not only greatly increases the difficulty of installation by requiring grooving on the solid objects, but also affects the strength of the solid objects and can easily cause damage. At the same time, traditional dampers are fixed to the hinge head, as shown in CN201810924103.5. Although they can achieve buffering, they produce a lot of impact noise and are also prone to damage to the damper support core, thus limiting their applicability. Summary of the Invention

[0032] In this embodiment, the damper structure is located at the edge of the substrate, and both the substrate and the damper structure are disposed within the base. Since the damper structure is located at the edge of the substrate and both are mounted on the base, the overall thickness of the structure can be reduced, achieving an ultra-thin effect. It can also reduce collision noise when the door panel is closed, and it is not easy to damage the support chip of the damper.

[0033] Meanwhile, the support frame includes a horizontal panel 51 and a vertical panel 52 at right angles. The horizontal panel is disposed on the surface of the base plate, and the vertical panel is located on the side of the cabinet door side panel. In this embodiment, the horizontal panel refers to the surface parallel to the panel surface of the cabinet door side panel. Since the vertical panel of the support frame can be located on the side of the cabinet door side panel, it is not necessary to open mounting slots on the cabinet door side panel during assembly, which improves the convenience and efficiency of assembly.

[0034] During assembly, one end of the support base is connected to the aluminum frame of the door panel via a pivot structure, and the other end is fixed to the vertical panel with screws.

[0038] In this embodiment, the pivot structure includes two shaft protrusions 81 and a spring 82 disposed between the two shaft protrusions. During assembly, the support base has a shaft hole, and the shaft protrusions and spring are disposed within the shaft hole. The ends of the two shaft protrusions extend out of both ends of the support base and are connected to the aluminum frame of the door panel. During assembly, a bushing can be provided between the shaft protrusions and the shaft hole to reduce friction and improve stability during use. Furthermore, in practical applications, to facilitate installation and maintenance of the spring, a spring mounting groove can be provided on the support base, along with a pressure cap fixed by screws.

[0039] In this embodiment, the base plate is provided with several adjustment slots extending in different directions; the base plate is connected to the base by upper and lower adjustment screws 13, door back gap adjustment screws 14, and locking screws 15. This can meet the installation and adjustment needs of different situations, ensuring stable and reliable installation. Meanwhile, a dust cover 16 is snapped onto the base, improving the overall aesthetics.
