Nowadays, there are various types of doors and windows, and different design requirements have different functions. Among them, the airtightness requirement of doors and windows is an important part of energy-saving design.

[0003] Chinese patent CN106088954B authorized and announced on December 5, 2017 discloses a folding door and window opening and closing mechanism, which includes a frame, a folding fan and an opening and closing drive device. The technical key points are that the folding fan is hinged with a hinge, the upper opening fan is hinged with the frame, the transmission shaft arranged on both sides of the lower opening fan is assembled in the transmission slide groove of the frame, the linkage shaft is assembled in the linkage slide groove of the linkage plate on both sides of the frame, the guide pulley group on the linkage plate inserted in the guide slide groove makes the linkage plate slide up and down along the guide slide groove, the linkage plate slides along the guide slide groove driven by the opening and closing drive device, and the driving linkage shaft slides synchronously along the linkage slide groove, so that the folding fan is opened or closed. In the upper and lower parts of the above application documents, since the door and window panels are in the same vertical plane in the initial stage, there is a sealing strip or sealing belt at the hinge between the upper window sash and the lower window sash, which can be referred to. Fig.15 As shown, when the upper and lower window sashes are opened or closed, they will squeeze the sealing strip or sealing belt, and the friction generated will cause the need to overcome greater friction or inertia when opening or closing. Since the two parts of the door and window panels are tightly fitted and are subject to additional resistance from components such as the sealing strip, a greater pulling force is required to overcome these resistances when starting to open, causing certain inconveniences. Summary of the invention

[0004] In order to solve the problem in the prior art that the upper and lower door and window panels are in the same vertical plane in the initial stage, resulting in the need to overcome greater friction or inertia when opening, and since the two parts of the door and window panels are tightly fitted and may be subject to additional resistance from components such as sealing strips, a greater pulling force is required to overcome these resistances when starting to open. To this end, the present invention proposes an energy-saving lifting and folding door and window, which can drive the movement of the upper and lower window sashes through the movement of parts, thereby reducing the lifting force.

The sliding connection makes the opening and closing of the lower window sash smoother, and may also provide a certain degree of sound insulation and dust prevention effects.

[0014] The difference from the prior art is that the beneficial effects of this application are:

This surface contact can increase the contact area, thereby distributing the pressure more evenly, which is particularly important for scenes that need to withstand greater pressure or maintain sealing. Notches 1 512 are provided on both sides of the rear end of the upper window sash 200, and a stopper 513 is fixedly connected to the rear end surface of the upper window sash 200. A square groove 516 is provided on the bottom surface of the window frame 100. A transverse baffle 511 and a square pressure plate 518 are vertically slidably connected to the inner wall of the square groove 516. The bottom of the transverse baffle 511 is fixedly connected to the top of the square pressure plate 518. The two side surfaces of the square pressure plate 518 are fixedly connected to half-side gear strips 523, and are connected to the one-way gear 5 21 are meshed with each other. By directly fixing the half-side gear bar 523 to the two side surfaces of the square pressure plate 518, the need for additional transmission components and connectors is reduced, thereby simplifying the entire structure. This simplification not only reduces the manufacturing cost, but also improves the reliability and maintainability of the system. The surface of the square pressure plate 518 is slidably connected to the inner wall of the protection box 501, and an air pressure bag 519 is arranged at the bottom. A switch 520 is hinged on the side of the square groove 516 close to the outside. The left and right sides of the protection box 501 are fixedly connected with an electric telescopic rod 524. The output end of the electric telescopic rod 524 is rotatably connected with a one-way gear 521. A wire 522 is arranged between the electric telescopic rod 524 and the switch 520. The surface of the wire 522 is arranged inside the protection box 501.By placing the wire 522 inside the protection box 501, the electrical components can be effectively isolated from direct contact with the external environment, preventing safety hazards such as short circuit and leakage caused by moisture, corrosion, wear or accidental touch, which improves the overall electrical safety. The bottom surface of the window frame 100 is fixedly connected to the limit strip 514.

[0042] When the window is in a closed state, since the upper window sash 200 and the lower window sash 300 form a same vertical plane with the window frame 100 in the closed position, and there is an extruded sealing strip between the hinges of the upper window sash 200 and the lower window sash 300, a larger pulling force is required when opening. When in use, a person manually rotates the handle assembly 600 at the bottom of the lower window sash 300 on one side of the room to rotate the handle assembly 600 inside the lower window sash 300. It is explained here that the pull rod 1 601 and the pull rod 2 602 of the handle assembly 600 are respectively located on the handle assembly 600 in the longitudinal direction of the pull rod 1 601 and the horizontal direction of the pull rod 2 602. When the pull rod 1 601 is rotated, the pull rod 2 602 is rotated downward with the handle assembly 600 as the center, and the pull rod 2 602 is rotated downward. Through the square groove 516 on the window frame 100, it is explained here that there is a switch 520 inside the square groove 516, and the switch 520 is hinged on the right side of the center of the square groove 516. When the handle assembly 600 is rotated, the pull rod 2 602 rotates clockwise and contacts the back side of the switch 520, which will not trigger the switch 520. Only when the pull rod 2 602 rotates counterclockwise can the switch 520 be triggered to squeeze the horizontal baffle 511 inside it to move vertically downward, and at the same time drive the square pressure plate 518 connected to the bottom of the horizontal baffle 511 to move in the protection box 501. It is explained here that when the square pressure plate 518 moves downward in the protection box 501, the half gear strips 523 on both sides are meshed with the one-way gears 521 on both sides of the protection box 501. Movement, since the tooth shape of the one-way gear 521 determines its force transmission direction, when the driving wheel rotates, the tooth shape will make the driven wheel follow the rotation, thereby realizing torque transmission, and when the driven wheel tries to rotate in the opposite direction, the tooth shape will make the driven wheel unable to follow the rotation, thereby preventing the reverse transmission of torque, so as to achieve the effect of preventing the air pressure bag 519 from rebounding after the square pressure plate 518 squeezes the air pressure bag 519 inside the protection box 501, so that the air pressure inside the air pressure bag 519 is transmitted to the air pressure telescopic rod 504 through the air pressure pipe 503 connected on both sides of the protection, thereby driving the air pressure telescopic rod 504 to extend, and pushing the push rod 505 at its output end to move inside the window frame 100, and at the same time, the rack 506 is used on the surface of the push rod 505, with The gear 507 on its side rotates, and the rotation of the gear 507 drives the support rod 508 to rotate synchronously. It is explained here that one end of the support rod 508 rotates on the inner side of the bottom of the window frame 100, and the other end rotates on the inner wall of the groove 700, and a directional telescopic rod 509 is fixed on the surface. When the support rod 508 rotates, it drives the directional telescopic rod 509 to rotate. It is explained here that when the window is closed, the output end of the directional telescopic rod 509 fits in the notch 512 of the upper window sash 200. When rotating, the pressure block 510 at the output end of the directional telescopic rod 509 pushes the upper window sash 200 toward the outside of the window frame 100 along the inner side of the notch 512, so that the upper window sash 200 and the lower window sash 300 form an initial open state reference in the window frame 100. Fig.13 At the same time, after opening, the directional telescopic rod 509 uses the force of squeezing the upper window sash 200 to slide the pressure block 510 at its output end out of the slot 512, and the directional telescopic rod 509 remains vertical to the outside of the window frame 100, while not hindering the subsequent movement of the upper window sash 200 and the lower window sash 300. The personnel applies an upward force to the lower window sash 300, so that the lower window sash 300 moves upward along the window frame 100 to the final position. Figure 5 ;

[0043] The process of closing the window is the reverse process of the above steps. First, the bottom of the lower window sash 300 is pulled to the bottom of the window frame 100 and fits with the limit strip 514. Fig.12 When the handle assembly 600 is turned, since the pull rod 2 602 is in the longitudinal direction when the window is opened, the pull rod 2 602 will enter the square groove 516 in the window frame 100, and then by rotating counterclockwise, the pull rod 2 602 will contact and trigger the switch 520. The switch 520 transmits a signal to the electric telescopic rod 524 through the wire 522 on the rear side, so that the electric telescopic rod 524 retracts, driving the one-way gear 521 connected to its surface to move synchronously, so as to move the one-way gear 521 away from the half-side gear bar 523. Since the half-side gear bar 523 loses the restraint of the one-way gear 521, the square pressure plate 518 on the surface will be pushed out and moved upward by the air pressure bag 519 at the bottom, so that the air pressure telescopic rod 504 and the push rod 505 will retract synchronously, and then drive the meshing gear 507 and the support rod 508, and the directional telescopic rod 509 at the top of the support rod 508, because the window frame is in a vertical state when it is opened, when it rotates, the pressure block 510 at the output end of the directional telescopic rod 509 squeezes the two sides of the rear side of the upper window sash 200, giving the upper window sash 200 a thrust toward the room. During the pushing process, since both sides of the pressure block 510 are curved surfaces, they cooperate with the stopper 513 on the rear side of the upper window sash 200, and the stopper 513 is also a curved surface, which cooperates with the pressure block 510. However, after the upper window sash 200 and the lower window sash 300 are closed, the pressure block 510 uses the curved surface and the telescopic ability of the directional telescopic rod 509 between the stopper 513 to make the pressure block 510 slide into the near slot 512 to prepare for the next opening of the window.
