DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Before understanding the technical solutions proposed in the present application, it is clear that the triggering mechanism of the electric shading curtain 4 is to install a trigger on the outer surface of the contact baffle 305. When the trigger is impacted, the electric shading curtain 4 releases the mechanical self-locking of the shading curtain. At this time, the shading curtain naturally falls along the shading curtain gap 5 under the action of gravity, and after being fully unfolded, a continuous shading surface is formed to cover the gap. When the door and window piece 7 is opened, the connecting ring rod 303 is reset under the tension of the return spring 304, driving the arc-shaped ring 302 to swing back and pushing the elastic trigger rod 301. In addition, the trigger is triggered again, and the rotating wing piece frame 306 is forced to rotate reversely to the initial position. At this time, the bent connecting wing piece is reinserted into the limiting groove on the side of the electric shading curtain 4, completing the automatic recovery and locking of the shading curtain. In this process, the adsorption force generated between the neodymium iron boron magnetic suction piece and the top surface of the door and window frame 1 can effectively prevent the shading curtain from accidentally slipping off, and the closed shading curtain gap 5 can block the external pollutants from entering the sliding area of the window rail frame 2.

[0030] In addition, it also needs to be pointed out that the lock block structure is provided between the two door and window pieces 7 in the present application. Since the lock block structure provided between the two door and window pieces 7 is a common knowledge in the existing door and window technical field, the applicant does not make specific description and explanation.

[0031] Reference Figures 1-4 It can be known that the scheme provided in the application includes a triggering assembly 3, which includes a connecting ring rod 303.

[0032] It should be noted that the connecting ring rod 303 is installed in the carrying notch 6 at the top of the door and window frame 1 in a hinged manner, and a width-adjustable electric shielding curtain 4 is arranged between the two connecting ring rods 303. The electric shielding curtain 4 is woven by double-layer glass fiber base cloth clamping shape memory alloy wires, and realizes magnetic connection with N52 level magnetic flux density through a rare earth permanent magnet array embedded on the top surface of the door and window frame 1.

[0033] In addition, it should be supplemented that in the application, a functional gap of 12-15 mm is reserved between the two door and window pieces 7 assembled inside the door and window frame 1, and a noise reduction sealing rubber strip is embedded in the functional gap. A shielding curtain notch 5 with a width of 18 mm is opened in the area corresponding to the functional gap on the top surface of the door and window frame 1 by using a laser cutting process, and the edge of the notch is chamfered and polished. In addition, it should be noted that a triggering piece made of 6061-T6 aluminum alloy is arranged between the connecting ring rod 303 and the electric shielding curtain 4. When the triggering piece is subjected to mechanical impact on the connecting ring rod 303 by the door and window piece 7, the limiting buckle completes the decoupling action within 0.3 seconds, so that the shielding curtain is lowered to the functional gap along the preset shielding curtain notch 5.

[0034] As a preferred embodiment, in the embodiment, the connecting ring rod 303 is rigidly connected to a φ10 mm hinged rod along its central axis through an M8 level high-strength bolt. The hinged rod is connected to the inner walls on both sides of the carrying notch 6 through self-aligning ball bearings at both ends, and the rotation angle range is set to ±35°. Four groups of SUS316 stainless steel return springs 304 are fixed between the 304 stainless steel contact surface arranged on the outer periphery of the connecting ring rod 303 and the inner wall surface of the carrying notch 6 in a spacing of 150 mm. The spring stiffness coefficient is 80 N / mm. The extension parts at both ends of the connecting ring rod 303 are processed into trapezoidal threads by a numerical control lathe, and are respectively assembled with a Q235 contact baffle 305 with a thickness of 6 mm and an arc-shaped ring 302 with an R15 circular arc radius. It should be supplemented that the surface of the contact baffle 305 is plated with hard chromium, and the contact surface flatness with the window rail frame 2 is 0.01 mm, which is used to receive the impact from the door and window piece 7.

[0035] As a preferred embodiment, in the embodiment, the window rail frame 2 is precisely drawn from a 6063-T5 aluminum alloy profile, and a double-row oil-containing bronze slide rail is arranged inside. The slide rail working surface roughness Ra is ≤0.8 μm. The polytetrafluoroethylene slide block embedded at the bottom of the contact baffle 305 forms a dynamic fit with the window rail frame 2, and the friction coefficient is controlled to be below 0.08. In addition, it is referred to Figure 4It can be known that, in the embodiment, the trigger core mechanism comprises a central shaft, two sides of the central shaft are fixed with connecting flaps, in addition, two ends of the central shaft are rotatably connected with the side wall of the curtain gap 5 through the Morse taper sleeve with a taper of 1:10, one end of one connecting flap is outwardly contacted, the other connecting flap is fixed with an elastic trigger rod 301, the elastic trigger rod 301 is used for contacting the arc-shaped ring 302.

[0036] Finally, it should be noted that, in the application, the N35UH grade neodymium iron boron magnetic suction piece embedded on both sides of the bottom surface of the electric shielding curtain 4 is filled with epoxy resin to form an IP54 protection level, the adsorption force between the magnetic suction piece and the galvanized steel plate on the top surface of the door and window frame 1 reaches 180N / 100cm² after testing, which ensures that the curtain body remains stable and adheres to the state under the 8-level wind force.

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the attached embodiments and their equivalents.
