[0027] As shown in the Figures 1 to 3As shown, the buffer assembly reduces the impact force when the electric folding screen window 2 is closed and opened, the buffer assembly is connected with the screen window frame 1, the buffer assembly includes a bottom plate 3 fixedly connected at the bottom of the electric folding screen window 2, a connecting groove 301 is formed at each corner of the inside of the bottom plate 3, a fixed frame 302 is fixedly connected at both sides of the inner cavity of each connecting groove 301, a sliding block 303 is slidably connected at the outside of each two fixed frames 302, a limiting elastic sheet 304 is fixedly connected at both sides of the inner wall of the connecting groove 301, a resisting groove 305 is formed at both sides of the sliding block 303, a connecting plate 307 is screwed at the opening of both ends of the connecting groove 301, a buffer column 306 is fixedly connected at the top and bottom of the sliding block 303, a connecting hole for the movement of the buffer column 306 is formed in the inside of the connecting plate 307, a buffer spring 308 is fixedly connected between each connecting plate 307 and the sliding block 303, each buffer spring 308 is sleeved at the outside of the buffer column 306, a deformation groove is formed in the inside of the limiting elastic sheet 304, a weakening groove is formed at the bottom of both sides of the limiting elastic sheet 304, the buffer assembly is in an unforced state, the sliding block 303 is located at the middle or slightly upper position of the connecting groove 301, the buffer spring 308 is in a natural length or slightly compressed state, the limiting elastic sheet 304 has a certain elasticity due to the deformation groove formed in the inside, can be deformed when subjected to external force and restored to the original state, when the electric folding screen window 2 starts to close, the bottom will drive the bottom plate 3 and the whole buffer assembly to move downward, the sliding block 303 slides downward along the connecting groove 301 under the guidance of the fixed frame 302, at the same time, the buffer spring 308 is compressed, a large amount of impact force is absorbed in the compression process of the buffer spring 308, so that the closing process of the screen window becomes stable, when the resisting groove 305 of the sliding block 303 contacts with the limiting elastic sheet 304, the limiting elastic sheet 304 will be deformed, further absorbing the impact force, and preventing the sliding block 303 from moving excessively, when the electric folding screen window 2 starts to open, the bottom will drive the bottom plate 3 and the whole buffer assembly to move upward, at this time, the buffer spring 308 starts to release the stored energy, pushes the sliding block 303 to slide upward along the connecting groove 301, the upward movement of the sliding block 303 makes the limiting elastic sheet 304 gradually restore to the original state, further assisting the stable opening of the screen window, the buffer assembly effectively reduces the impact force generated when the electric folding screen window 2 is closed and opened through the joint action of the buffer spring 308 and the limiting elastic sheet 304, protects the screen window itself and the wall or decoration around the window, since the buffer assembly can reduce the mechanical stress of the screen window in the opening and closing process, therefore can significantly prolong the service life of the screen window, reduce the maintenance and replacement cost of the user, the buffer assembly provides a stable support and buffering effect for the screen window, helps to maintain the stability of the screen window in the opening and closing process, avoids the safety hidden danger caused by shaking or shaking, the introduction of the buffer assembly makes the opening and closing process of the screen window more stable and quiet, improves the user experience. Users no longer need to worry about the screen window producing excessive noise or impact force when opening and closing.
[0028] In addition, the top of the inner cavity of the screen window frame 1 is provided with a docking groove which is matched with the shape of the bottom plate 3, so that the electric folding screen window 2 can be completely stored when the screen window is stored, thereby effectively avoiding the screen window from being exposed for a long time and accumulating dust and sundries, which not only affects the appearance, but also affects the air permeability and insect prevention effect of the screen window. The screen window can be stored to keep clean and prolong the service life.
[0029] The working principle of the utility model provides that when the screen window needs to be opened, the electric folding screen window 2 starts to work under the power drive, and slides downward along the guide rail 4 through the pulley block 5 until the screen window is completely unfolded and covers the window. At this time, the screen window can effectively prevent small insects such as mosquitoes from entering the room, while ensuring the circulation of indoor air. When the screen window needs to be closed, the electric folding screen window 2 is started again, and slides upward along the guide rail 4 through the pulley block 5 until the screen window is completely stored in the mounting cavity. In this way, the screen window is completely hidden, which not only saves space, but also avoids visual interference. At the same time, when the electric folding screen window 2 starts to close, the bottom part drives the bottom plate 3 and the entire buffer assembly to move downward, the sliding block 303 slides downward along the connecting groove 301 under the guidance of the fixed frame 302, and the buffer spring 308 is compressed at the same time. The compression process of the buffer spring 308 absorbs a large amount of impact force, so that the closing process of the screen window becomes smooth. When the abutting groove 305 of the sliding block 303 contacts the limiting spring piece 304, the limiting spring piece 304 will be deformed, further absorbing the impact force and preventing the sliding block 303 from moving excessively. When the electric folding screen window 2 starts to open, the bottom part drives the bottom plate 3 and the entire buffer assembly to move upward. At this time, the buffer spring 308 starts to release the stored energy, pushing the sliding block 303 to slide upward along the connecting groove 301. The upward movement of the sliding block 303 makes the limiting spring piece 304 gradually restore to its original state, further assisting the smooth opening of the screen window. The buffer assembly effectively reduces the impact force generated when the electric folding screen window 2 is closed and opened through the joint action of the buffer spring 308 and the limiting spring piece 304, protecting the screen window itself and the wall or decoration around the window. Since the buffer assembly can reduce the mechanical stress of the screen window during the opening and closing process, the service life of the screen window can be significantly prolonged, and the maintenance and replacement cost of the user can be reduced.
