[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] This utility model provides a light and shadow adjustment device for building exterior shading. The device includes: two opposing horizontal beams 1; vertical beams 11 connected to both ends of the two horizontal beams 1 on their relatively close sides, and the two horizontal beams 1 and the two vertical beams 11 are connected; a light and shadow adjustment component is provided between the two vertical beams 11, and the angle of sunlight can be adjusted by the light and shadow adjustment component; a shading component is provided inside the two horizontal beams 1, and the intensity of sunlight can be adjusted by the shading component.

[0021] It should be noted that the two opposing horizontal beams 1 form the lateral support foundation of the entire light and shadow adjustment device. They stably bear part of the weight from the vertical beams 11, the light and shadow adjustment components, and the sunshade components, ensuring the stability of the entire device after installation. This prevents swaying, deformation, or even collapse due to its own weight or external wind forces, providing solid support for the normal operation of the device. Glass can be installed at the top and bottom of the frame formed by the two horizontal beams 11 and the vertical beams 11, creating a physical protective barrier. This protects the light and shadow adjustment components and the sunshade components, extending their lifespan and reducing maintenance costs caused by damage from foreign objects. The light and shadow adjustment components located between the two vertical beams 11 can adjust the angle of sunlight, making the indoor light distribution more even. The sunshade components within the two horizontal beams 1 can effectively adjust the intensity of sunlight. In hot summers, reducing the intensity of sunlight can reduce indoor heat absorption; in cold seasons, appropriately adjusting the sunshade components allows more sunlight to enter the room, utilizing solar energy to raise the indoor temperature and reduce heating energy consumption.

[0022] In an embodiment of this utility model, the light and shadow adjustment assembly includes multiple parallel adjustment blades 2, which are equidistantly distributed between two vertical beams 11. Both ends of each adjustment blade 2 are rotatably connected to the two vertical beams 11. Multiple gears 21 are rotatably connected to the inner walls of the two vertical beams 11. The relatively close sides of the two opposing gears 21 are connected to the adjustment blades 2 through the inner walls of the vertical beams 11 via connecting shafts. The bottom of each gear 21 is meshed with a toothed plate 22. A guide rod 23 is slidably connected to the inner side of the toothed plate 22 on the same side. Both ends of the guide rod 23 are connected to the inner wall of the crossbeam 1. A first driving member for driving one of the gears 21 to rotate is installed on one side of one of the vertical beams 11. A connecting frame 24 is connected between every two adjacent toothed plates 22. Limit blocks 25 are connected to both ends of each toothed plate 22.

[0023] It should be noted that the multiple parallel and equidistantly distributed adjusting blades 2 between the two vertical beams 11 are key components for directly adjusting the angle of sunlight. Through their rotation, they change the direction of sunlight incidence, thereby optimizing the indoor light distribution. Multiple gears 21 rotatably connected to the inner walls of the two vertical beams 11 are connected to the adjusting blades 2 via connecting shafts, transmitting the power provided by the first driving component to the adjusting blades 2. When the first driving component drives one of the gears 21 to rotate, the meshing relationship between the gears and their engagement with the toothed plate 22 causes the other gears 21 to rotate synchronously, thus enabling all adjusting blades 2 to rotate in unison, achieving unified adjustment of the sunlight angle. The guide rod 23 is connected at both ends to the inner wall of the crossbeam 1, providing guidance for the linear movement of the toothed plate 22. This ensures that the toothed plate 22, driven by the gears 21, can only slide along the axial direction of the guide rod 23, preventing the toothed plate 22 from shifting or wobbling during movement, thus guaranteeing the stability and reliability of the entire light and shadow adjustment assembly. The first driving component, installed on one side of one of the vertical beams 11, is an electric motor, providing the power source for the entire light and shadow adjustment assembly. It drives one of the gears 21 to rotate, triggering a series of transmission reactions that ultimately achieve the rotation of all the adjusting blades 2. The first driving component can flexibly adjust the angle of sunlight according to actual needs, such as the angle of sunlight at different times of day and the light requirements of people indoors.

[0024] In an embodiment of this utility model, the sunshade assembly includes a winding rod 3 rotatably connected to two crossbeams 1 respectively. A sunshade cloth 31 is wound around the outer side of one winding rod 3, and winding ropes 32 are wound around both ends of the outer side of the other winding rod 3. The ends of the two winding ropes 32 away from the winding rod 3 are connected to the sunshade cloth 31. Spur gears 33 are installed at both ends of the outer side of the two winding rods 3. The two spur gears 33 are connected by a synchronous belt drive. A second driving member for driving the winding rod 3 to rotate is installed at one end of one of the crossbeams 1. Slide grooves for the sunshade cloth 31 to pass through are opened on both crossbeams 1 and both vertical beams 11.

[0025] It should be noted that the two rotating winding rods 3, each rotatably connected within the two crossbeams 1, play a crucial role in storing and releasing the sunshade fabric 31 and the winding rope 32. One winding rod 3 is used to wind the sunshade fabric 31. When sunshade is needed, rotating this winding rod 3 unfolds the sunshade fabric 31; when sunshade is not needed, rotating the winding rod 3 in the opposite direction rewinds the sunshade fabric 31 back onto the rod. The other winding rod 3 has the winding rope 32 wound around its outer ends. During the unfolding or retracting of the sunshade fabric 31, the winding rope 32, in conjunction with the stretching and winding of the sunshade fabric 31, ensures the smooth operation of the sunshade fabric 31. The winding rods 3 rotate under the action of the second drive component, thereby driving the movement of the sunshade fabric 31 and the winding rope 32. The spur gears 33 installed at the outer ends of the two winding rods 3 are connected by a synchronous belt drive, ensuring that the two winding rods 3 can rotate synchronously. During the unfolding or retracting of the sunshade fabric 31, this synchronous transmission method ensures that the movement of the winding rope 32 and the sunshade fabric 31 is coordinated and consistent. The power output from the second drive component, connected to the winding rod 3, is converted into the unfolding or retracting action of the sunshade cloth 31, thereby adjusting the intensity of sunlight. The second drive component is an electric motor. The sunshade cloth 31 is a key component that directly blocks sunlight. On hot, sunny days or during periods of intense sunlight, the unfolded sunshade cloth 31 effectively blocks a large amount of sunlight, reducing the intensity of sunlight entering the room, lowering the indoor temperature, and reducing the operating load of air conditioning and other cooling equipment, thus achieving energy conservation and emission reduction. Simultaneously, it prevents direct sunlight from hitting indoor items, avoiding fading and aging due to sun exposure, and extending the lifespan of the items. The sliding grooves on the two crossbeams 1 and two vertical beams 11, which allow the sunshade cloth 31 to pass through, provide guidance for its movement. During the unfolding or retracting process, the sliding grooves ensure that the sunshade cloth 31 moves along a predetermined trajectory, preventing deviation, jamming, or derailment during movement, thus ensuring the stability and reliability of the sunshade assembly.
