Detailed Embodiments

[0023] To achieve the above objectives and effects, the technical means and structure adopted by the present invention will be described in detail in combination with the accompanying drawings for the preferred embodiments of the present invention to explain its features and functions.

[0024] As Figures 1-7 shown, the present invention provides a rotatable and conformable building curtain wall structure, which includes a plurality of composite board assemblies 1. The composite board assembly 1 includes a heat insulation layer 11, a heat storage layer 12, and a heat absorption layer 13 arranged in sequence. The cross-section of the composite board assembly 1 is a parallelogram, and a support shaft 14 is arranged in the middle of the composite board assembly 1. It also includes two support columns 3 fixed on the outer surface of the building 4. Rotating assemblies 2 are arranged on both sides of each composite board assembly 1, and the composite board assembly 1 is respectively connected to the two support columns 3 through the rotating assemblies 2 on both sides. The rotating assembly 2 includes a mounting plate 21 and two parallel connecting rods 22. The mounting plate 21 is arranged parallel to the support column 3. One end of the connecting rod 22 is rotatably connected to the mounting plate 21, and the other end is rotatably connected to the support column 3. An installation groove 211 is arranged in the mounting plate 21, a vertically arranged sliding hole 212 is opened in the installation groove 211, the support shaft 14 is slidably arranged in the sliding hole 212, a flywheel mechanism 214 is installed on the support shaft 14, and a first rack 213 cooperating with the flywheel mechanism 214 is fixedly installed in the installation groove 211. The support column 3 is a hollow structure, and a driving mechanism for driving the connecting rod 22 to rotate is arranged inside the support column 3. The flywheel mechanism 214 includes a first gear 2141, a bearing 2143, and a ratchet tooth 2144. The first gear 2141 is installed on the support shaft 14 through the bearing 2143, the ratchet tooth 2144 is installed on the support shaft 14, and an internal ratchet structure 2142 is arranged at one end of the first gear 2141.

[0025] In this embodiment, when there are significant changes in the external climate, the driving mechanism drives the connecting rod 22 of the rotating assembly 2 to rotate upward by a certain angle, thereby moving the mounting plate 21 away from the outer surface of the building 4 and leaving a rotating space for the composite board assembly 1. Under the action of its own gravity, the composite board assembly 1 drives the support shaft 14 to slide downward along the sliding hole 212, and the first gear 2141 rotates downward along the first rack 213. Under the limiting action of the ratchet teeth 2144, the inner ratchet structure 2142 drives the support shaft 14 to rotate, causing the composite board assembly 1 to rotate 180°. The heat insulation layer 11 and the heat absorption layer 13 exchange positions. After the composite board assembly 1 completes rotation, the driving mechanism drives the connecting rod 22 of the rotating assembly 2 to rotate downward and reset. Under the guiding action of the triangular cushion block 7 at the bottom of the building 4, the bottommost composite board assembly 1 rises until it fits the outer surface of the building 4. During the movement process, the composite board assembly 1 drives the support shaft 14 to slide upward along the sliding hole 212, and the first gear 2141 rotates upward along the first rack 213. Since the ratchet teeth 2144 cannot limit the position, the inner ratchet structure 2142 no longer drives the support shaft 14 to rotate. The other composite board assemblies 1 rise under the guiding action of the inclined surface at the top of the lower composite board assembly 1. The composite board assembly 1 adopts a parallelogram structure, which is convenient for movement guiding on the one hand and can make the composite board assemblies 1 fit tightly without gaps on the other hand.

[0026] In another embodiment, as Figure 4 shown, a second rack 216 meshing with the first gear 2141 is further slidably disposed in the mounting groove 211. The second rack 216 is disposed opposite to the first rack 213 to improve the movement stability of the first gear 2141.

[0027] In another embodiment, as Figure 4 、 Figure 5As shown, a viscous damper 215 and a limit post 217 are further provided in the installation groove 211. The viscous damper 215 is located below the second rack 216. A spring 218 is provided at the end of the limit post 217, and the spring 218 is used to snap the limit post 217 onto the second rack 216. Elastic protrusions 2171 are provided on the limit post 217, and inclined surfaces are provided on the elastic protrusions 2171. At one end where the upper connecting rod 22 of the rotating assembly 2 is connected to the mounting plate 21, a first rotating shaft 221 is provided, and a lever 2211 that cooperates with the elastic protrusion 2171 is provided on the first rotating shaft 221. When the connecting rod 22 rotates upward, the first rotating shaft 221 rotates relative to the mounting plate 21, causing the lever 2211 to push the elastic protrusion 2171 in the direction of the spring 218, driving the limit post 217 to move in the direction of the spring 218, and causing the limit post 217 to disengage from the second rack 216. After the second rack 216 loses its limiting effect, it can be driven by the first gear 2141 to move downward, and the impact vibration is reduced through the viscous damper 215, improving the movement stability. When the connecting rod 22 rotates downward and resets, the first gear 2141 drives the second rack 216 to move upward to the highest point, and the limit post 217 is re-snapped onto the second rack 216 under the action of the spring 218 for limiting, further improving the structural stability.

[0028] In another embodiment, the driving mechanism adopts a motor, a hydraulic motor or a rotary cylinder; the output end of the driving mechanism is connected to one of the connecting rods 22 of the rotating assembly 2.

[0029] In another embodiment, as Figure 7 shown, the driving mechanism includes a third rack 82 and a hydraulic cylinder 81; the third rack 82 is slidably arranged in the support column 3, and the lower end of the third rack 82 is fixedly connected to the output end of the hydraulic cylinder 81. At one end where the connecting rod 22 is connected to the support column 3, a second rotating shaft 222 is provided, and a second gear 83 is fixedly arranged on the second rotating shaft 222, and the second gear 83 meshes with the third rack 82. By pulling the third rack 82 downward through the hydraulic cylinder 81, the connecting rod 22 is rotated upward; by pushing the third rack 82 upward through the hydraulic cylinder 81, the connecting rod 22 is rotated downward. The gravity of the third rack 82 is jointly restricted by the gravity of the plurality of composite plate assemblies 1, reducing the work done against gravity and saving driving energy. As a preferred embodiment, when the hydraulic cylinder 81 pulls, it can be in two gears. When in the first gear, the top surface of the composite plate assembly 1 can be perpendicular to the outer surface of the building 4 (as Figure 2 shown), realizing ventilation and sunshading, and facilitating the dehumidification or cooling of the outer surface of the building 4; when in the second gear, the composite plate assembly 1 can complete a 180° rotation.

[0030] In another embodiment, it further includes a temperature sensor 5, a photosensitive sensor 6 and a controller; the temperature sensor 5, the photosensitive sensor 6 and the controller are all arranged outdoors; the temperature sensor 5, the photosensitive sensor 6 and the driving mechanism are all electrically connected to the controller. The temperature and light values sensed by the temperature sensor 5 and the photosensitive sensor 6 are transmitted to the controller, so that the driving mechanism is controlled by the controller to drive the rotating assembly 2 to rotate, and finally the automatic rotation of the composite board assembly 1 is realized.

[0031] The above are only the preferred embodiments of the present invention, not all embodiments. Anyone should know that the structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, all belong to the protection scope of the present invention.
