[0017] For example, see Figure 1-Figure 4 This embodiment provides a three-section hinge structure for a storage door, which includes a door body 1, a cabinet body 2, an upper mounting seat 3, a lower mounting seat 4, a support seat 5, a matching seat 6, a middle shell 7 and a thrust bearing 8.

[0018] The upper mounting seat 3 and the lower mounting seat 4 are respectively arranged on the upper and lower ends of one side of the door body 1, and the support seat 5 is arranged on the cabinet body 2 corresponding to the position below the upper mounting seat 3. Preferably, a stepped protrusion 51 is provided on the mounting surface of the support seat 5, and a mounting recess adapted to the stepped protrusion 51 is provided on the cabinet body 2. The matching of the stepped protrusion 51 with the mounting recess facilitates the accurate positioning and installation of the support seat 5, thereby improving the structural stability.

[0019] The support seat 5 is provided with an assembly cavity 52 adapted to the thrust bearing 8. The thrust bearing 8 is located in the assembly cavity 52. The bottom surface of the upper mounting seat 3 is in contact with the thrust bearing 8 and is provided with an upper rotating shaft 31 extending into the inner ring of the thrust bearing 8. The support seat 5 cooperates with the thrust bearing 8 to support the weight of the entire door body 1. The thrust bearing 8 has a good load-bearing effect and significantly reduces friction, thereby improving the structural stability and smoothness of the door body 1, making the door body 1 easier to open and close, and more labor-saving for users to operate. Preferably, an axial through hole 32 is provided on the upper rotating shaft 31, and a side through hole 33 connected to the axial through hole 32 is provided on the side of the upper mounting seat 3 close to the door body 1. A lower through hole 53 is provided on the support seat 5 at a position corresponding to the axial through hole 32. The lower through hole 53 and the axial through hole 32 are on the same axis and are connected. The side through hole 33, the axial through hole 32 and the lower through hole 53 are interconnected, allowing wires or other slender objects to pass through, which facilitates circuit wiring or maintenance without affecting the integrity of the structure and the smoothness of operation.

[0020] The mating seat 6 is arranged on the cabinet body 2 above the lower mounting seat 4. Preferably, a stepped boss 61 is provided on the mounting surface of the mating seat 6, and the cabinet body 2 is provided with an assembly recess that matches the stepped boss 61. The stepped boss 61 cooperates with the assembly recess, which facilitates the precise positioning and installation of the mating seat 6, thereby improving the structural stability. The mating seat 6 is provided with an axis hole 62, and the lower mounting seat 4 is provided with a lower rotating shaft 41 that extends into the lower axis hole 62. The upper rotating shaft 31 and the lower rotating shaft 41 are coaxial, ensuring that the door body 1 can open and close smoothly.

[0021] To facilitate installation with the door body 1, an upper recess 34 is provided on the upper mounting seat 3 near the side of the door body 1. An upper connecting plate 11 is provided on the upper recess 34 and is fixed to the upper recess 34 by welding. An upper elongated mounting hole is provided on the upper connecting plate 11, and an upper circular mounting hole that matches the upper elongated mounting hole is provided on the door body 1. A lower recess 42 is provided on the lower mounting seat 4 near the side of the door body 1. A lower connecting plate 12 is provided on the lower recess 42 and is fixed to the lower recess 42 by welding. A lower elongated mounting hole is provided on the lower connecting plate 12, and a lower circular mounting hole that matches the lower elongated mounting hole is provided on the door body 1. It is easy to install and allows adjustment within a certain range to ensure perfect fit between the door body 1 and the cabinet body 2.

[0022] After installation, the upper mounting seat 3 is covered with an upper shell 9, and the lower mounting seat 4 is covered with a lower shell 10, providing excellent protection and an aesthetically pleasing appearance. The upper end of the middle shell 7 is covered over the support seat 5, and the lower end extends vertically downward and covers the mating seat 6. Since the upper mounting seat 3 and the lower mounting seat 4 are symmetrically located at the upper and lower ends of the side of the door body 1 to form the upper and lower sections, and the support seat 5 and mating seat 6 are covered by the middle shell 7 to form the middle section, the overall three-section structure has excellent protection and an aesthetically pleasing appearance.
