Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a wind pressure resistant assembly structure for a flat-frame electric lifting window. Background Technology

[0002] Electric lift windows are widely used in modern architecture due to their convenient opening and clean lines. Among them, flush-frame electric lift windows (where the window sash and frame are essentially on the same plane when closed) are particularly favored for their neat and aesthetically pleasing appearance. However, flush-frame designs also present challenges: due to the small overlap between the window sash and frame, traditional single-seal methods are prone to seal failure under strong wind pressure due to slight deformation of the profile, leading to air leaks and water seepage, severely impacting window performance and user experience. Conventional sealing methods often employ unidirectional or parallel multi-seal configurations, resulting in a single-direction sealing pressure. Under strong wind pressure, gaps can easily appear in the seals, making it difficult to meet the high-performance requirements of flush-frame windows. Utility Model Content

[0003] The purpose of this utility model is to provide a wind-pressure resistant assembly structure for a flat-frame electric lifting window. Through a unique cross-pressure sealing design, it effectively resists strong wind pressure and prevents sealing failure, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind pressure resistant assembly structure for a flat-frame electric lifting window, comprising a window frame and a movable sash and a fixed sash disposed within the window frame. The lower end of the movable sash near the interior is provided with a first sealing structure, which includes a first pressure strip and a first sealing strip fixed to the movable sash. The upper end of the fixed sash near the exterior is provided with a second sealing structure, which includes a second pressure strip and a second sealing strip fixed to the fixed sash. When the movable sash is closed, the first pressure strip presses against the second sealing strip, and the second pressure strip presses against the first sealing strip, thereby forming a cross-pressure structure at the junction of the movable sash and the fixed sash.

[0005] Furthermore, the first pressure strip is integrally formed with the profile of the movable fan and extends obliquely upward; the second pressure strip is integrally formed with the profile of the fixed fan and extends obliquely downward.

[0006] Furthermore, the first sealing structure also includes a third sealing strip fixed to the movable fan. When the movable fan is closed, the third sealing strip is pressed against the profile surface of the fixed fan to form an additional sealing line located upstream of the cross-pressing sealing structure.

[0007] Furthermore, the second sealing structure also includes a fourth sealing strip fixed to the fixed fan. When the movable fan is closed, the fourth sealing strip is pressed against the profile surface of the movable fan to form an additional sealing line downstream of the cross-pressing sealing structure.

[0008] Compared with existing technologies, this technical solution provides a wind-pressure resistant assembly structure for a flat-frame electrically operated lifting window, which has the following advantages:

[0009] 1. A cross-pressing sealing structure is formed by the first pressure strip on the movable fan and the second sealing strip on the fixed fan, as well as the second pressure strip on the fixed fan and the first sealing strip on the movable fan. This structure transforms the wind pressure from indoors and outdoors into a tighter sealing pressure, significantly improving the reliability of the seal and its wind pressure resistance.

[0010] 2. The glazing bead and window sash profile are integrally molded, ensuring the rigidity and stability of force transmission. The glazing bead adopts an inclined extension design, which can play a guiding role during the closing of the movable sash and ultimately achieve a stable and durable compression seal.

[0011] 3. Additional sealing lines consisting of third and fourth sealing strips can be set on the inner and outer sides of the core cross-pressure sealing structure to form a multi-stage sealing system, further enhancing the overall airtightness and watertightness.

[0012] 4. This structure is specially designed for flat frames with small overlap. It achieves the best sealing effect in a limited space through the ingenious principle of cross-pressure, effectively solving the problem of easy leakage in flat frame windows. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] like Figures 1 to 2 As shown, the wind pressure resistant assembly structure of a flat-frame electric lifting window provided by this utility model mainly includes a window frame 10, a movable sash 20, and a fixed sash 30. The movable sash 20 and the fixed sash 30 are basically flush on the vertical surface, forming a flat-frame design;

[0021] The movable sash 20 has a first sealing structure at its lower end on the side closest to the interior. This first sealing structure includes a first pressure strip 201 and a first sealing strip 202 fixed to the movable sash 20. The fixed sash 30 has a second sealing structure at its upper end on the side closest to the exterior. This second sealing structure includes a second pressure strip 301 and a second sealing strip 302 fixed to the fixed sash 30. When the movable sash 20 is closed, the first pressure strip 201 presses against the second sealing strip 302, and simultaneously, the second pressure strip 301 presses against the first sealing strip 202. The fit between these two pairs of pressure strips and sealing strips is not parallel but rather cross-corresponding, thus forming a unique cross-pressure structure at the junction of the movable sash 20 and the fixed sash 30. When wind pressure acts on the window sash, this structure converts the pressure into a force that tightens the seal, greatly improving the reliability of the seal.

[0022] The first pressure strip 201 and the profile of the movable fan 20 are preferably manufactured as a single piece to ensure structural strength and stability. The first pressure strip 201 extends obliquely upward from the profile body of the movable fan 20. Correspondingly, the second pressure strip 301 and the profile of the fixed fan 30 are also integrally molded and extend obliquely downward from the profile body of the fixed fan 30. This oblique extension design allows for smooth guidance and gradual compression between the first pressure strip 201 and the second sealing strip 302, and between the second pressure strip 301 and the first sealing strip 202, during the closing process of the movable fan 20, ultimately achieving a stable interference fit.

[0023] To create multiple layers of sealing protection, the first sealing structure also includes a third sealing strip 203. This third sealing strip 203 is fixed to the movable fan 20 and located inside the first pressure strip 201 and the first sealing strip 202 (i.e., the side closer to the interior). When the movable fan 20 is closed, the third sealing strip 203 presses against the profile surface of the fixed fan 30, thereby forming an additional sealing line upstream of the cross-pressing sealing structure (relative to the direction in which airflow may intrude). This constitutes the first important line of defense.

[0024] The second sealing structure also includes a fourth sealing strip 303; this fourth sealing strip 303 is fixed to the fixed sash 30 and located outside the second pressure strip 301 and the second sealing strip 302 (i.e., the side closer to the outside). When the movable sash 20 is closed, the fourth sealing strip 303 is pressed against the profile surface of the movable sash 20, thereby forming an additional sealing line downstream of the cross-pressing sealing structure, constituting the outermost sealing line.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
