Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware, and in particular to a window opening transmission mechanism and a door / window. Background Technology

[0002] Currently, among common window opening and closing devices, the hand-cranked window opener is a widely used existing technology. This device opens and closes the window sash through a hand-cranked drive mechanism, but it has the following drawbacks:

[0003] Issues with structural aesthetics and installation stability: The sash and frame of a hand-cranked window opener are usually exposed on the visible surface of the window and fixed with screws. This design not only affects the overall aesthetics of the window, but also makes it prone to structural instability due to loose screws after long-term use.

[0004] The window requires significant closing force and lacks a self-locking function: When the window sash is near the locked position, this structure requires considerable closing force to achieve a seal. Furthermore, due to the lack of a self-locking function, the window sash may spring back a certain distance under the rebound force of the sealing strip, resulting in a poor seal and affecting the window's sound insulation, heat insulation, and waterproofing performance.

[0005] In summary, existing hand-cranked window openers are inadequate in terms of aesthetics, structural stability, and sealing performance, and an improved solution is urgently needed to address these issues. Utility Model Content

For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

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

[0030] The automatic window opening device 3 can automatically open or close the sash 2 by setting an automatic rotation drive or operating tool 4 outside the frame 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. The frame profile 10 has a groove 101. 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 located in the groove 101. The output end of the translation transmission component 22 is rotatably connected to the other end of the connecting rod 21 and is used to push the connecting rod 21 to translate in order 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 external rotational force to the translation transmission component 22.

[0032] In this design, the automatic window opening device 3 directly integrates the window opening transmission mechanism 20 into the groove 101 of the frame profile 10, avoiding exposure of the mechanism and resulting in a more aesthetically pleasing overall appearance. The rotational force is transmitted to the translational transmission component 22 via the flexible rotation component 23. The translational transmission component 22 then drives one end of the connecting rod 21 to translate, at which point the other end of the connecting rod 21 can push the fan body 2 to open or close. The movement of the translational transmission component 22 driven by the flexible rotation component 23 is stable, preventing the fan body 2 from swaying due to environmental influences.

[0033] In this embodiment, the groove 101 is a C-shaped groove. The translation transmission component 22 includes a frame base 221 and a fastener 222. The width of the frame base 221 is smaller than the opening width of the C-shaped groove, which is used to sink the translation transmission component 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-shaped groove, that is, the frame profile 10 in this solution is a conventional and universal profile. The translation transmission component 22 structure of this solution can be directly installed in the existing universal frame profile 10, avoiding the need to redesign the profile and saving costs. At the same time, it can be used to automate the opening of existing manual casement windows. 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 mounting groove 2211 facilitates the installation and positioning of the frame base 221 and the stable connection between it 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 towards one side of the C-shaped groove so that the mounting groove 2211 engages with the groove wall. Finally, use fasteners 222 to secure the frame base 221, thus achieving stable positioning. The mutual engagement between the frame base 221 and the C-shaped groove allows for a simple and stable connection of the frame base 221, facilitating installation and replacement.

[0036] In this embodiment, the translational transmission assembly 22 further includes a lead screw 223 and a nut seat 224. One end of the lead screw 223 is connected to the other end of the flexible rotation assembly 23, and the other end of the lead screw 223 is rotatably connected to the frame base 221. The nut seat 224 is threadedly connected to the lead screw 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 lead screw 223 is a rotating component, and the nut seat 224 is threadedly connected to the lead screw 223. Rotation of the lead screw 223 can drive the nut seat 224 to move back and forth. When the nut seat 224 moves back and forth, the connecting rod 21, which is rotatably connected to it, will rotate to open and close the fan body 2. It should be noted that the frame base 221 is provided with a sliding plate that is aligned with the length direction of the lead screw 223, and the nut seat 224 passes through the sliding plate, thereby ensuring the stability of the nut seat 224 during the back and forth movement. Because the screw 223 nut mechanism has self-locking properties, it can solve the problem of the rubber strip rebounding when the window sash is close to closing.

[0037] In this embodiment, the flexible rotation assembly 23 includes an outer tube, an inner core, an outer connecting fitting, and an inner connecting fitting. The inner core is disposed inside the outer tube, the outer connecting fitting is fixedly connected to the outer tube, and the inner connecting fitting is fixedly connected to the inner core. The inner connecting fitting is rotatably connected to the outer connecting fitting. The flexible rotation assembly 23 is a flexible shaft structure, and the inner core is a steel wire rope connected to the inner core through the inner connecting fittings at both ends, thereby transmitting rotational force. Both the inner core and the outer tube are bendable and steerable structures, thus ensuring the transmission of rotational force at any angle.

[0038] In this embodiment, one end of the lead screw 223 is provided with a first connecting part, and the inner connecting accessory is provided with a second connecting part. The first connecting part and the second connecting part cooperate with each other to transmit the rotational force of the inner core to the lead screw 223. The first connecting part is a hexagonal shaft, and the second connecting part is a hexagonal bushing. The first transmission part and the second transmission part are in hexagonal contact, which can stably realize the transmission of rotational force.

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

[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, and an operating opening is provided in the outer frame profile 11 for installing the operating panel 24. A heat insulation, sound insulation, and waterproofing strip can 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 general-purpose profiles. If automatic doors and windows are to be produced or existing doors and windows are to be modified, only an operating opening needs to be provided on the outer frame profile 11. The length of the flexible rotating component 23 can be adjusted according to the width of the strip. The flexible rotating component 23 only has two ends connected to the lead screw 223 and the operating panel 24, respectively. The middle part does not contact the frame profile 10, so it will 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 operation panel 24 in this solution can be located on the side or bottom of the frame 1. Similarly, the window opening transmission mechanism 20 can also be located on the side or bottom of the frame 1.

[0042] In this embodiment, the window opening transmission mechanism 20 also includes a panel cover 25, which is closable and connected to the operation panel 24 to conceal the operation panel 24. The panel cover 25 covers the operation panel 24, concealing it and enhancing the overall aesthetics of the frame 1.

[0043] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
