[0002] Currently, among the common devices for opening and closing windows, a manual window opener is a widely used existing technology solution. This device uses a manual drive mechanism to open and close the window sash, but it has the following drawbacks:

[0003] Issues with structural aesthetics and installation stability: The sash and frame of a manual window opener are typically exposed directly on the visible side of the window and secured with screws. This design not only affects the overall aesthetics of the window, but also can lead to a loss of structural stability due to loosening of screws over time.

[0004] High closing force required and lack of self-locking function: When the window sash approaches the locked position, the structure requires a high closing force to complete the seal. In addition, due to the lack of self-locking function, the window sash may rebound a certain distance due to the rebound force of the rubber strip, resulting in a loose seal and affecting the window's sound insulation, heat insulation, and waterproof performance.

[0005] In summary, the existing hand-operated window openers have deficiencies in aesthetics, structural stability and sealing performance, and an improved solution is urgently needed to solve the above problems. Summary of the Invention

[0029] See also Figure 1This embodiment discloses a door and window, including a frame 1 and a fan 2, with an automatic window opening device 3 provided between the frame 1 and the fan 2.

[0030] The automatic window opening device 3 can realize automatic opening or closing of the fan body 2 by arranging an automatic rotating driving member or operating member 4 outside the frame body 1.

[0031] See further Figure 2-5 The automatic window opening device 3 includes a frame profile 10 and a window opening transmission mechanism 20. A groove 101 is provided in the frame profile 10; the window opening transmission mechanism 20 includes a connecting rod 21, a translation transmission component 22 and a flexible rotation component 23. One end of the connecting rod 21 is connected to the fan body 2; the translation transmission component 22 is provided in the groove 101, and the output end of the translation transmission component 22 is rotationally connected to the other end of the connecting rod 21, which is used to push the connecting rod 21 to translate to open and close the fan body 2; one end of the flexible rotation component 23 extends out of the frame profile 10, and the other end of the flexible rotation component 23 is connected to the input end of the translation transmission component 22. The flexible rotation component 23 is used to transmit the external rotational force to the translation transmission component 22.

[0032] The automatic window opening device 3 of this embodiment incorporates the window opening transmission mechanism 20 directly into the recess 101 of the frame profile 10, preventing exposure and enhancing the overall aesthetics. A flexible rotating assembly 23 transmits the rotational force to the translational transmission assembly 22, which then drives one end of the connecting rod 21 to translate. The other end of the connecting rod 21 then pushes the window sash 2 open or close. The flexible rotating assembly 23 drives the translational transmission assembly 22 to move stably, preventing the window sash 2 from shaking due to environmental influences.

[0033] In this embodiment, the groove 101 is a C-shaped groove, and the translation transmission assembly 22 includes a frame base 221 and a fastener 222. The width of the frame base 221 is smaller than the notch width of the C-shaped groove, and is used to sink the translation transmission assembly 22 into the C-shaped groove. The fastener 222 is used to connect the frame base 221 to the bottom of the C-shaped groove. It should be noted that the C-shaped groove is a European standard C-groove, that is, the frame profile 10 of this solution is a conventional general profile. The structural setting of the translation transmission assembly 22 of this solution can be directly installed in the existing general frame profile 10, avoiding the need to re-open the mold and design the profile, saving costs, and at the same time, it can be used to transform the existing manual casement window into an automated window opening. The solution is simple and easy to implement.

[0034] In this embodiment, the frame base 221 is provided with a mounting groove 2211, which is used to snap onto the groove wall of the C-shaped groove. The provision of the mounting groove 2211 facilitates the installation and positioning of the frame base 221 and the stable connection between the frame base 221 and the C-shaped groove.

[0035] When installing the frame base 221, first lower the frame base 221 into the bottom of the C-shaped groove, then move the frame base 221 toward one side of the C-shaped groove so that the mounting groove 2211 is snap-fitted to the groove wall of the C-shaped groove, and then secure the frame base 221 with the fasteners 222, thereby achieving stable positioning of the frame base 221. The mutual cooperation between the frame base 221 and the C-shaped groove allows for a simple and stable connection of the frame base 221, making installation and replacement convenient.

[0036] In this embodiment, the translation transmission assembly 22 further includes a screw rod 223 and a nut seat 224. One end of the screw rod 223 is connected to the other end of the flexible rotation assembly 23, and the other end of the screw rod 223 is rotatably connected to the frame base 221. The nut seat 224 is threadedly connected to the screw rod 223 and slidably connected to the frame base 221. The other end of the connecting rod 21 is connected to the nut seat 224. The screw rod 223 is a rotating member, and the nut seat 224 is threadedly connected to the screw rod 223. Rotation of the screw rod 223 drives the nut seat 224 to move back and forth. When the nut seat 224 moves back and forth, the connecting rod 21 rotatably connected to it rotates to open and close the fan body 2. It should be noted that a slide is provided on the frame base 221 in the same length direction as the screw rod 223, and the nut seat 224 is inserted into the slide to ensure the stability of the nut seat 224 during its back and forth movement. Since the screw rod 223 nut mechanism has a self-locking property, the problem of the rubber strip rebounding when the window sash is close to closing can be solved.

[0037] In this embodiment, the flexible rotating assembly 23 comprises an outer tube, an inner core, an outer connecting fitting, and an inner connecting fitting. The inner core is disposed within the outer tube, the outer connecting fitting is fixedly connected to the outer tube, the inner connecting fitting is fixedly connected to the inner core, and the inner connecting fitting is rotatably connected within the outer connecting fitting. The flexible rotating assembly 23 is a flexible shaft structure, with the inner core being a steel wire rope connected to the inner core via inner connecting fittings at both ends, thereby transmitting rotational force. Both the inner core and the outer tube are bendable and steerable, ensuring that rotational force can be transmitted at any angle.

[0038] In this embodiment, a first connecting portion is provided at one end of the screw rod 223, and a second connecting portion is provided at the inner connecting fitting. The first and second connecting portions cooperate to transmit the rotational force of the inner core to the screw rod 223. The first connecting portion is a hexagonal shaft, and the second connecting portion is a hexagonal sleeve. The hexagonal contact between the first and second transmission portions ensures stable transmission of the rotational force.

[0039] In this embodiment, the window opening transmission mechanism 20 further includes an operating panel 24. One end of the flexible rotating assembly 23 is connected to the operating panel 24. The operating panel 24 is connected to the outside of the frame 1 and is used to apply a rotational force to the flexible rotating assembly 23 from the outside. The operating panel 24 can be directly connected to an external automatic drive member such as a motor or an electric motor to achieve fully automatic window opening, or can be manually rotated by inserting the operating member 4, such as Figure 5 As shown, semi-automatic window opening is achieved.

[0040] In this embodiment, the frame profile 10 includes an outer frame profile 11 and an inner frame profile 12. A groove 101 is provided in the inner frame profile 12. The outer frame profile 11 is provided with an operating port for mounting an operating panel 24. Heat-insulating, sound-insulating, waterproof, and other spacer strips may be provided between the outer frame profile 11 and the inner frame profile 12. Both the outer frame profile 11 and the inner frame profile 12 are universal profiles. For the production of automatic doors and windows or the modification of existing doors and windows, it is only necessary to provide an operating port on the outer frame profile 11. The length of the flexible rotating assembly 23 can be adjusted according to the width of the spacer strips. Only the two ends of the flexible rotating assembly 23 are connected to the screw rod 223 and the operating panel 24, respectively. The middle portion does not contact the frame profile 10, which does not affect the normal use of the frame profile 10 or require modification of the frame profile 10.

[0041] It should be noted that the operating panel 24 in this solution can be arranged on the side or bottom of the frame 1 , and similarly, the window opening transmission mechanism 20 can also be arranged on the side or bottom of the frame 1 .

[0042] In this embodiment, the window opening transmission mechanism 20 further includes a panel buckle cover 25, which is openably connected to the operation panel 24 and is used to hide the operation panel 24. The panel buckle cover 25 is arranged outside the operation panel 24 to hide the operation panel 24, thereby enhancing the overall aesthetics of the frame 1.

[0043] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
