[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] A high wind pressure resistant aluminum alloy door and window, such as Figures 1 to 8 As shown, it includes an outer frame 100, a glass installation frame 101, a glass 102 and a handle 103. The outer frame 100 is composed of a fixed frame 104 and an adjustable frame 105. The fixed frame 104 is fixedly installed on the wall. The glass installation frame 101 is installed on the fixed frame 104 through the adjustable frame 105. One end of the adjustable frame 105 is rotatably connected to the fixed frame 104, and the other end of the adjustable frame 105 can swing inward. A cavity 106 is provided at a position of the fixed frame 104 near the other end of the adjustable frame 105. A retractable windshield assembly 200 for guiding airflow is installed in the cavity 106.

[0034] The retractable windshield assembly 200 includes an outer windshield 201 and a plurality of inner windshields 202 arranged in an inner-outer direction and mounted in the fixed frame 104. The outer windshield 201 is fixedly mounted on the fixed frame 104 and is located outside the inner windshield 202. The inner windshield 202 is mounted in the fixed frame 104 in a connection manner that allows it to slide left and right. When all the inner windshields 202 are deployed, they can form a stepped overall shape to block the junction between the edge of the adjustable frame 105 and the fixed frame 104. The innermost inner windshield 202 is in contact with the front end surface of the glass 102 mounting frame 101 and the adjustable frame 105.

[0035] A movable boss 203 corresponding to all internal wind shields 202 is installed in the fixed frame 104. The left end of the movable boss 203 is stepped and a contact-type adsorption connection component 300 is installed between the internal wind shield 202. A limit platform 204 is provided in the fixed frame 104 to limit the maximum retraction stroke of the internal wind shield 202.

[0036] The outer end surface of the window is divided into an unadjustable fixed outer end surface composed of the wall and the fixed frame 104, and an adjustable movable outer end surface composed of the glass mounting frame 101 and the adjustable frame 105. The inward swinging movement of the adjustable frame 105 will cause the movable outer end surface to be inclined relative to the fixed outer end surface, with an angle formed therebetween. When the glass 102 is tilted accordingly, the flow direction of the airflow on the outer surface of the glass 102 can be changed, reducing the vertical impact of the airflow with the surface of the glass 102, thereby reducing the resistance of the airflow to the window.

[0037] In addition, the unfolded internal wind shield 202 can form an overall inclined platform-shaped structure at the junction of the edge of the adjustable frame 105 and the fixed frame 104, that is, the junction of the fixed outer end surface and the movable outer end surface, to guide the airflow direction of the outer end surface of the glass 102, so that the airflow flows more smoothly through the edge of the window, reduce the pressure concentration at the edge of the window, reduce the pressure received by the window, and improve the window's ability to resist wind pressure.

[0038] like Figure 7 As shown, the adsorption connection assembly 300 includes an adsorption metal sheet 301 installed on the right end of the internal windshield 202 , and a plate-shaped magnetic material 302 corresponding to each adsorption metal sheet 301 is installed on the left end of the movable boss 203 .

[0039] like Figure 4 As shown, a support guard plate 107 is installed in the fixed frame 104, which is respectively abutted against the top and bottom of the inner wall of the cavity 106. The outer end of the support guard plate 107 is abutted against the inner end of the movable boss 203. A gear rack assembly 400 for controlling the left and right lateral movement of the movable boss 203 is installed in the cavity 106. A cam connecting rod assembly 500 for controlling the swing and reset action of the adjustable frame 105 is installed in the cavity 106. A support positioning frame 108 is installed at the bottom of the cavity 106. The gear rack assembly 400 and the cam connecting rod assembly 500 are both connected to the support positioning frame 108.

[0040] The swinging and resetting action of the adjustable frame 105 is realized by the cam-link assembly 500. After the adjustable frame 105 swings inward and the telescopic windshield assembly 200 is unfolded, although the window's wind pressure resistance can be improved compared to conventional windows in this state, it will make the glass mounting frame 101 difficult to open normally. Therefore, the adjustable frame 105 is controlled to move to a tilted state only when the wind speed is high and there is a need to resist high wind pressure. In other cases, the adjustable frame 105 maintains a normal state and does not affect the normal opening and closing action of the glass mounting frame 101.

[0041] like Figure 7 and Figure 8As shown, the gear rack assembly 400 includes a rotating shaft 401 installed inside the cavity 106 and connected to the support positioning frame 108, a plurality of gears 402 are installed on the rotating shaft 401, and a through hole 403 corresponding to each gear 402 is provided on the support protective plate 107. A rack 404 corresponding to each gear 402 is installed at the inner end of the movable boss 203, and the rack 404 passes through the through hole 403 and engages with the corresponding gear 402. A first motor 405 powered by the rotating shaft 401 is installed in the cavity 106.

[0042] like Figure 6 and Figure 8 As shown, a connecting frame 501 extending into the cavity 106 is fixedly installed on the adjustable frame 105, and the connecting frame 501 is located on the inner side of the support protective plate 107. A limiting groove 502 is provided on the connecting frame 501. The cam connecting rod assembly 500 includes two cams 503 which are rotatably installed in the cavity 106 and are respectively located on the upper and lower sides of the connecting frame 501. A connecting rod 504 is installed between the two cams 503 and passes through the limiting groove 502.

[0043] When the cam 503 rotates clockwise, it can drag the adjustable frame 105 along with the connecting frame 501 to swing inward through the connecting rod 504. When the cam 503 rotates counterclockwise, it can drag the adjustable frame 105 along with the connecting frame 501 to swing outward until it is reset.

[0044] like Figure 4 and Figure 6 As shown, a driving shaft 505 connected to the support and positioning frame 108 and a second motor 506 connected to the driving shaft 505 are installed in the cavity 106, a driving gear 507 close to the cam 503 is installed on the driving shaft 505, and a driven gear 508 meshing with the driving gear 507 is installed on the cam 503, and the driven gear 508 coincides with the central axis of the cam 503.

[0045] like Figure 3 and Figure 7 As shown, a fixed dustproof plate 109 is installed at the inner opening of the cavity 106. A notch 110 is provided on the fixed dustproof plate 109 for the connection frame 501 to move. A retractable dustproof plate 111 is installed on the connection frame 501 to block the notch 110.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
