Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 This utility model provides a technical solution: Example 1 addresses the aforementioned problem: existing sliding doors for home cabinets mostly rely on manual pushing and pulling, which has the drawbacks of being laborious to operate and having insufficient driving precision. Furthermore, existing sliding doors lack a reliable upper and lower guide structure, making them prone to shaking and unstable operation during the extension and retraction process.

[0015] The solution is as follows: A retractable cabinet door includes a device body 1, which includes an external mounting frame 2 and a folding door device 3. The folding door device 3 is installed inside the external mounting frame 2. The external mounting frame 2 includes a lower frame 4, a first side frame 5, a second side frame 6, and a top frame device 7. The first side frame 5 is installed at the left end of the lower frame 4, the second side frame 6 is installed at the right end of the lower frame 4, and the top frame device 7 is installed between the first side frame 5 and the second side frame 6. The folding door device 3 includes an auxiliary louver block 12, a main louver block 13, an upper drive slider 14, and a lower guide slider. 15. The auxiliary louver block 12 is located to the right of the main louver block 13. The auxiliary louver block 12 is provided in several groups and is distributed in a horizontally equidistant manner. A folding hinge 18 is provided between the main louver block 13 and the auxiliary louver block 12. A folding hinge 18 is also provided between the several groups of the auxiliary louver blocks 12. The upper drive slider 14 is located at the top of the main louver block 13. A drive hole 16 is opened on the side of the upper drive slider 14. The lower guide slider 15 is located at the bottom of the main louver block 13. A guide hole 17 is opened on the side of the lower guide slider 15. A transparent window 19 is provided on the surface of both the auxiliary louver block 12 and the main louver block 13.

[0016] Analysis of the above content: The upper drive slider 14 is driven by the top frame device 7 to move linearly, and the lower guide slider 15 moves synchronously along the guide rod 25 of the lower frame 4; the main louver block 13 and the auxiliary louver block 12, and each group of auxiliary louver blocks 12, achieve folding / unfolding actions through the folding hinge 18, thereby driving the entire folding door device to extend and retract; when the folding door device 3 is unfolded, the folding hinge 18 extends, and the main and auxiliary louver blocks are arranged in sequence to close the cabinet opening; when the folding door device 3 is retracted, the folding hinge 18 folds, and the main and auxiliary louver blocks retract to one side, revealing the cabinet opening; the structure of the folding hinge 18 makes the door extension and retraction process flexible and smooth; the transparent window 19 allows direct observation of the cabinet interior, improving functionality; the dual cooperation of the upper drive slider 14 and the lower guide slider 15 provides stable motion support for the door, avoiding swaying during extension and retraction, and solving the problem of unstable operation in the prior art.

[0017] Example 2: Please refer to Figure 1-5 This utility model provides a technical solution based on Embodiment 1: The top frame device 7 includes a drive rail 8, a motor mounting rail 9, a drive motor 10, and a drive threaded rod 11. The motor mounting rail 9 is installed at the right end of the drive rail 8, the drive threaded rod 11 is installed inside the drive rail 8, the drive motor 10 is installed inside the motor mounting rail 9, the drive end of the drive motor 10 is connected to one end of the drive threaded rod 11, and the drive threaded rod 11 passes through the drive hole 16.

[0018] Analysis of the above content: After the drive motor 10 starts, the drive end drives the drive threaded rod 11 to rotate within the drive rail 8. Since the drive threaded rod 11 passes through the drive hole 16 of the upper drive slider 14, the rotational motion of the threaded rod can be converted into the linear motion of the upper drive slider 14, thereby driving the folding door device 3 to achieve the telescopic action. When the drive motor 10 rotates forward, the drive threaded rod 11 drives the upper drive slider 14 to move to one side, and the folding door device 3 unfolds (closes the cabinet). When the drive motor 10 rotates in reverse, the upper drive slider 14 moves to the other side, and the folding door device 3 folds and retracts (opens the cabinet). The electric drive method replaces the traditional manual push and pull, making operation more labor-saving. The thread transmission accuracy between the drive threaded rod 11 and the drive hole 16 is high, ensuring the accuracy of the telescopic action and solving the defects of the existing technology, such as laborious manual operation and insufficient drive accuracy.

[0019] Example 3: Please refer to Figure 1-5 The present invention provides a technical solution based on Embodiment 1: the first side frame 5 and the second side frame 6 each include a main embedding block 20 and a mounting block 21. The mounting block 21 is mounted on the top of the main embedding block 20, and an embedding groove 22 is provided on the inner side of the main embedding block 20.

[0020] Analysis of the above content: The main embedding block 20 is used to connect and fix with the cabinet or mounting surface, the mounting block 21 assists in fixing the end of the top frame device 7, and the embedding groove 22 on the inner side of the main embedding block 20 can limit and guide the side of the folding door device 3, together forming a stable external mounting frame 2; during installation, the side frame is fixed to the left and right sides of the cabinet by the main embedding block 20, and the mounting block 21 is connected and fixed to the end of the top frame device 7 to form a complete frame structure; the structural design is stable, the installation method is simple, and it can effectively ensure the integrity of the external mounting frame 2, provide reliable structural support for the operation of the folding door device 3, and improve the reliability of the entire telescopic door.

[0021] Example 4: Please refer to Figure 1-5 The present invention provides a technical solution based on Embodiment 1: the lower frame 4 includes a guide frame 24 and a guide rod 25, the guide rod 25 is installed in the guide frame 24, and the guide rod 25 passes through the guide hole 17.

[0022] Analysis of the above content: The guide rod 25 is installed inside the guide frame 24 and passes through the guide hole 17 of the lower guide slider 15; when the lower guide slider 15 moves with the folding door device 3, the guide rod 25 provides lower linear guidance, which cooperates with the upper guide of the top frame device 7; during the extension and retraction of the folding door device 3, the lower guide slider 15 always moves in a straight line along the guide rod 25, which, together with the movement of the upper drive slider 14, guides the extension and retraction trajectory of the door; it provides lower guide support, forming a double upper and lower guide with the upper guide structure of the top frame device, which completely solves the problem of shaking and unstable operation caused by the lack of reliable upper and lower guides in existing telescopic doors, making the door run more smoothly.

[0023] Working principle: During operation, the external mounting frame 2 (composed of the lower frame 4, the first side frame 5, the second side frame 6, and the top frame device 7) provides a stable mounting foundation for the whole. After the drive motor 10 of the top frame device 7 is started, it drives the drive threaded rod 11 in the drive rail 8 to rotate. Since the drive threaded rod 11 passes through the drive hole 16 of the upper drive slider 14, the rotational motion is converted into the linear motion of the upper drive slider 14, thereby driving the extension and retraction of the folding door device 3. At the same time, the guide rod 25 of the lower frame 4 passes through the guide hole 17 of the lower guide slider 15, forming a double guide with the upper drive structure. Together with the folding hinges 18 between the main louver block 13 and the auxiliary louver block 12, and between the auxiliary louver blocks 12, the door can be smoothly folded / unfolded. Technical benefits: Electric drive replaces manual push-pull, solving the problem of laborious operation; threaded rod transmission improves drive accuracy; upper and lower double guide structure eliminates shaking during extension and retraction, ensuring smooth operation; folding hinge design makes extension and retraction flexible; transparent window 19 facilitates observation of the cabinet interior, enhancing the user experience; main embedding block 20, mounting block 21 and embedding groove 22 of the side frame enhance installation stability, ensuring overall structural reliability and overcoming the defects of existing technologies in all aspects.
