[0036] Reference Figures 1 to 6 As shown, the external expansion device provided by the utility model.

[0037] Example 1

[0038] It includes a window frame 2 arranged on a wall 1, a folding floor-to-ceiling window 3 located in the window frame, a fixed frame 4 slidingly arranged on the outside of the window frame, a number of telescopic rods 5 with both ends fixedly connected between the outer wall of the window frame and the fixed frame, and a driving unit 6 for driving the fixed frame to move closer to or away from the window frame; the folding floor-to-ceiling window adopts the existing structure, and the size of the fixed frame matches the size of the window frame; a protective plate 7 is provided on the fixed frame near the inner side of the window frame, the protective plate is rotatably connected to the fixed frame, and when the fixed frame is pushed out to the set position, the protective plate flips to a horizontal state; before the fixed frame is retracted to the window frame, the protective plate flips to a vertical state and fits against the inner side of the fixed frame.

[0039] In this embodiment, a fixed frame is installed on the outside of the floor-to-ceiling window. On a clear day, the user opens the window and uses a drive unit to push the fixed frame to the set position, causing the protective plate to flip to a horizontal position. The horizontal protective plate now creates a horizontal area outside the window frame (serving as a small balcony). This horizontal area is outdoors and exposed to sunlight, thereby increasing the area exposed to sunlight. Users can use this area to place flowers and plants, dry clothes on a clothesline, or air out daily necessities such as cured fish and meat; it's quick and convenient.

[0040] Example 2

[0041] The structure and principle of Example 2 are similar to those of Example 1, differing in that the protective plate is automatically flippable, and a linear drive assembly is provided between the protective plate and the fixed frame. The linear drive assembly is hinged at both ends to the protective plate and the fixed frame, respectively. The linear drive assembly is a conventional structure and can be implemented using a hydraulic cylinder, pneumatic cylinder, electric push rod, or the like.

[0042] To improve the stability of the guard plate in a horizontal position, several telescopic rods are horizontally arranged between the fixed frame and the outer wall of the window frame. When the guard plate is tilted to the horizontal position, the telescopic rods and the bottom surface of the guard plate are in contact. The telescopic rods further support the guard plate and bear the weight, making it more stable.

[0043] Example 3

[0044] The structure and principle of Example 2 are similar to those of Example 1, except that the protective plate is manually flippable, and a rotating card is provided on the inner side of the fixed frame near the window frame. The rotating card faces vertically downward under the action of gravity and forms a slot with the fixed frame. The rotating card is moved as needed to allow the upper side of the protective plate to engage with or disengage from the slot when it is in contact with the fixed frame.

[0045] Several telescopic rods are horizontally arranged between the fixed frame and the outer wall of the window frame. When the protective plate is flipped to the horizontal position, the telescopic rods and the bottom surface of the protective plate are in contact. The telescopic rods support the protective plate and bear the weight of the protective plate.

[0046] The user turns the rotating clamping plate to clamp the protective plate onto the fixing frame or detach it from the fixing frame.

[0047] In Examples 1-3, the surface of the protective plate in a horizontal state is provided with anti-slip material; preferably, a groove for placing items is provided on the upper surface of the protective plate in a horizontal state.

[0048] In Examples 1-3, based on the specific structure of the window frame, a preferred structural form of the drive assembly is given. Specifically,

[0049] The lower edge of the window frame is flush with the ground 12 inside the window frame; the drive assembly includes a moving rod 6-1, a guide rod 6-2, a threaded rod 6-3, a bevel gear set 6-4, and a motor 6-5; at least two grooves 8 are provided on the ground inside the window frame, perpendicular to the window frame and extending along the outside of the window frame; a threaded rod is provided in one of the grooves, and a guide rod is provided in the remaining grooves; the size of the moving rod matches the size of the groove, and one end of the moving rod is fixedly connected to the fixed frame;

[0050] A guide hole matching the guide rod is provided at the other end of the movable rod connected to the guide rod. The guide rod is fixed in the corresponding groove. The length of movement of the guide rod in the guide hole is greater than the sliding distance of the window frame.

[0051] The other end of the movable rod, connected to the threaded rod, has a threaded hole that matches the rod. The length of movement of the threaded rod within the threaded hole is greater than the sliding distance of the window frame. The movable rod is mounted in a corresponding groove via a mounting base, allowing only rotation. The driven teeth of the bevel gear assembly are located on the other end of the movable rod, and the driving teeth of the bevel gear assembly are connected to the motor. The motor drives the threaded rod to rotate, driving the movable rod within the groove, thereby controlling the fixed frame to move closer to or further away from the window frame. The guide rod and the movable rod serve as guides, increasing stability and preventing the fixed frame from falling.

[0052] In the embodiment shown in the figure, in order to ensure the consistency of the sizes of all grooves, a motor mounting cavity 9 is opened on the side of the groove where the threaded rod is located, and the motor is placed in the motor mounting cavity. The output shaft of the motor passes through the wall between the motor mounting cavity and the groove, and is connected to the threaded rod through a bevel gear set.

[0053] Among them, in order to improve the aesthetics, a cover plate of matching size is provided on the groove; in order to facilitate the installation of the telescopic rod, a plurality of mounting grooves 10 are provided on the wall outside the window frame, and the other end of the telescopic rod is fixed in the mounting groove.

[0054] In Examples 1-3, the folding floor-to-ceiling windows utilize a multi-section structure, consisting of multiple sections of window bodies interlocked with each other. The window bodies can rotate along a hinge axis when folded, allowing them to be stored parallel to the wall. Folding floor-to-ceiling windows are conventional structures and will not be discussed in detail here.

[0055] In Examples 1-3, multiple horizontal protection rods 11 are vertically spaced apart in the fixed frame to provide effective protection. The overall material uses existing lightweight and high-strength materials, such as carbon fiber or special alloys, to reduce the weight of the fixed frame and improve its load-bearing capacity.

[0056] The utility model also provides a folding window, which is characterized by adopting any of the above-mentioned outward expansion devices.

[0057] The working principle of this utility model:

[0058] During operation, the motor is activated, driving the bevel gear set to rotate, which in turn drives the threaded rod, thereby driving the movable rod to move, thereby extending or retracting the fixed frame. As the fixed frame extends outward, the telescopic rod and guide rod move synchronously with the movable rod. After the fixed frame is extended to the set position, the protective plate is rotated to form a temporary floor, and the telescopic rod can also temporarily bear the weight, providing greater stability. The French windows can slide, fold and retract against each other.

[0059] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
