In addition, flat folding doors can be used not only for home decoration, but also for workshops, shopping malls, office buildings and other places. After searching, the patent with publication number CN208702328U discloses an electric flat folding door, including a frame, a first door body, a second door body, an axial drive wheel and a radial drive wheel. The first door body is pivotally connected to the frame, and the second door body is slidably connected to the first door body; the second door body is connected to the axial The driving wheels are linked, and the first door body is linked with the radial driving wheel. The second door body can be retracted along the axis relative to the first door body, and the first door body can be rotated relatively, so that the electric folding door has both safety and efficient space utilization. However, it cannot retract and rotate at the same time. Both retraction and rotation can be completed by two sets of drive systems. However, its overall structure is complex and the cost is high. The electric control is complex, and the use and maintenance costs are high. For this reason, a folding door is designed that can use a set of drive structures to complete the extension and rotation operations, reduce costs, reduce operating and maintenance costs, and improve operational flexibility.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-5 A flat folding door comprises a fixed column 1 and a movable column 2, a sliding and retractable door body is arranged between the fixed column 1 and the movable column 2, one end of the sliding and retractable door body is hinged to one end of the fixed column 1, and the other end of the sliding and retractable door body is fixedly connected to the movable column 2, and a driving structure that can be adjusted in direction is provided at the bottom of the movable column 2, and the driving structure comprises a turntable 4 rotatably connected to the bottom of the movable column 2, and a plurality of groups of rollers 5 arranged in parallel are provided at the bottom of the turntable 4, and a driving mechanism for driving the plurality of rollers 5 to rotate is provided on the turntable 4, and a direction adjustment mechanism for driving the turntable 4 to rotate is also provided in the movable column 2.

[0024] Specifically, the driving mechanism includes a driving shaft rotatably connected to the turntable 4, and the driving shaft and multiple rollers 5 are connected through a synchronous belt 8. It also includes multiple guide wheels 7 adapted to the rollers 5. The turntable 4 also includes a driving motor 6 that drives the driving shaft. When the driving motor 6 is started, the driving shaft is driven to rotate. Through the cooperation of the rollers 5 and the multiple guide wheels 7, the synchronous belt 8 drives the multiple rollers 5 to rotate.

[0025] Specifically, the adjustment mechanism includes a support plate 9 fixedly mounted on the moving column 2 and located above the turntable 4. The bottom of the support plate 9 is rotatably connected to a gear 11, and the outside of the gear 11 is meshed with a gear ring 10. The bottom of the gear ring 10 is fixedly connected to the turntable 4 through multiple connecting bars 13. The top of the support plate 9 is fixedly mounted with an adjustment motor 12 for driving the gear 11 to rotate. Starting the adjustment motor 12 makes the output shaft of the adjustment motor 12 rotate clockwise or counterclockwise, so as to drive the gear 11 to rotate clockwise or counterclockwise, thereby driving the turntable 4 and multiple rollers 5 to rotate simultaneously through the cooperation of the gear ring 10 and multiple gears 11. Furthermore, the bottom of the moving column 2 is fixedly connected to a limit platform 3 that rotates and slides with the turntable 4. Through the setting of the limit platform 3, it is convenient to limit the turntable 4 and increase the stability during rotation.

[0026] Specifically, the sliding and retractable door body includes a plurality of fixed frames 17 arranged at intervals horizontally, a guide telescopic frame is provided between two adjacent fixed frames 17, the guide telescopic frame includes two hinged bars 23 rotatably connected by a central axis 18 in the middle, a U-shaped bar 22 is rotatably connected to the central axis 18, a slide groove is provided on the fixed frame 17 for guiding and sliding with the free end side of the hinged bar 23, a guide assembly is provided between the central axis 18 and the fixed frame 17, the guide assembly includes a center seat 19 and a fixed sleeve 21 respectively fixedly mounted on the central axis 18 and the fixed frame 17, the center seat 19 and the fixed sleeve 21 are respectively fixedly mounted on the central axis 18 and the fixed frame 17, The fixed sleeves 21 are connected by a telescopic rod 20. The arrangement of the two hinged bars 23 and the cooperation of the sliding grooves on the center axis 18 and the two fixed frames 17 facilitates extension and retraction. The arrangement of the U-shaped bar 22 facilitates shielding in the middle, ensuring the overall shielding after extension. The cooperation of the center seat 19, the telescopic rod 20 and the fixed sleeve 21 ensures that the center axis 18 is always at the middle height and remains unchanged, thereby increasing the overall stability of the overall sliding and retracting door body. Furthermore, the fixed frame 17 at one end is rotatably connected to the fixed column 1, and the fixed frame 17 at the other end is fixedly connected to the movable column 2.

[0027] Specifically, multiple universal wheels 16 are installed at the bottom of the fixed frame 17. Through multiple universal wheels 16, it is convenient to increase the contact points between the sliding and retractable door body and the ground, increase stability, and facilitate automatic angle adjustment during extension and rotation. Furthermore, the multiple universal wheels 16 can be rotatably connected to the bottom of the fixed frame 17 through a rotating disk, or can be directly installed to the bottom of the fixed frame 17.

[0028] Specifically, a photovoltaic panel 14 and an inspection cover 15 are installed on the top and back of the movable column 2 respectively. Furthermore, the photovoltaic panel 14 is electrically connected to the driving mechanism and the adjustment mechanism to facilitate the provision of electrical energy to the driving mechanism and the adjustment mechanism.
