Description

Technical Field

[0001] This invention belongs to the field of building door and window technology, specifically relating to a sliding door and window with switchable opening side. Background Technology

[0002] In modern architectural design, sliding windows and casement windows are two widely used forms, each favored for their space-saving and excellent sealing performance. With the increasing demand for spacious and open spaces, folding sliding windows have gradually become popular as an innovative design. This type of window cleverly combines the advantages of sliding and casement windows, achieving not only a large area of ​​transparency but also providing excellent ventilation and lighting performance, greatly enhancing the continuity between indoor and outdoor spaces. Therefore, folding sliding windows are highly favored in high-end residences, sunrooms, and scenic balconies—applications requiring a high degree of openness and spatial freedom. Nevertheless, the following problems still exist in the actual application of folding sliding windows:

[0003] Firstly, as frequently used building openings, doors and windows require easy operation and smooth opening and closing. However, most existing folding and sliding windows rely on manual operation, especially when there are many window sashes or the window area is large. The sliding resistance increases significantly, making the process laborious and inconvenient, which fails to meet the needs of modern buildings for intelligent and user-friendly operation.

[0004] Secondly, doors and windows are often located in key traffic flow positions transitioning between indoors and outdoors, with complex and varied spatial layouts on both sides. Users expect their opening methods to adapt to different spatial conditions. However, most folding sliding windows currently have fixed opening directions and closing methods after installation, typically only folding and closing to one side (left or right). This unidirectional retraction design restricts the flexible layout of architectural spaces, especially in scenarios near wall corners, with compact furniture arrangements, or asymmetrical spaces on both sides. It can easily cause obstructed opening or affect indoor traffic flow, reducing usability and space utilization.

[0005] Ultimately, doors and windows not only serve a passageway function but also need to adjust their opening state according to seasons, climate, and ventilation requirements. However, existing folding sliding doors and windows have limited functionality; most products only support linear sliding folding and lack complex movement modes such as rotation, casement, or multi-directional linkage. This functional limitation makes windows less adaptable to certain ventilation needs or special climatic conditions (such as directional wind guidance, rain protection, and ventilation), and unable to flexibly adjust their opening form according to actual usage scenarios, thus limiting their application potential in diverse architectural environments. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a sliding door and window with switchable opening side to solve the problems existing in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is a sliding door and window with switchable opening sides, including a frame, on which a plurality of window sashes with sliding functions are provided, and each window sash is provided with an opening and closing assembly at both ends in the height direction; the opening and closing assembly includes a slider and a connecting rod, the slider is slidably mounted on the frame, and the slider is detachably mounted at both ends in the width direction of the window sash; one end of the connecting rod is rotatably mounted on the slider, and the other end of the connecting rod is rotatably mounted in the middle area of ​​the window sash; by sliding the slider on the frame, the window sash slides on the frame; by controlling the connection and disconnection of the window sash and the sliders on both sides, the single-sided opening and closing switching of the window sash on the frame on the left and right sides can be realized.

[0008] Preferably, the slider and the window sash can switch between a rotatably connected state and a disconnected state. The sliders located at both ends of the window sash in the width direction are a first slider and a second slider, respectively. When the first slider and the window sash are rotatably connected and the second slider and the window sash are disconnected, the window sash is on the rotatable side of the first slider and on the opening / closing side of the second slider. When the first slider and the window sash are disconnected and the second slider and the window sash are rotatably connected, the window sash is on the rotatable side of the second slider and on the opening / closing side of the first slider.

[0009] Furthermore, the connecting rod is divided into a first connecting rod and a second connecting rod according to its connection with the first slider and the second slider. The end of the first connecting rod connected to the window sash and the end of the second connecting rod connected to the window sash are rotatably connected together and rotatably positioned in the middle of the window sash. Through the cooperation of the first connecting rod, the second connecting rod, the first slider and the second slider, the window sash on the frame can be opened and closed at 90 degrees.

[0010] Furthermore, the window sash is provided with opening and closing components on both sides in the width direction, and the opening and closing components are used to control the connection state between the window sash and the slider;

[0011] The opening and closing component includes a rotating component, a trigger component, and a connecting pin. Both the window sash and the slider have connecting holes. The connecting pin acts on the connecting holes to control the connection state of the window sash and the slider. The rotating component is rotatably mounted on the window sash, and the trigger component is slidably mounted on the window sash. One end of the trigger component acts on the connecting pin, and the other end of the trigger component is connected to the rotating component. The rotation of the rotating component drives the trigger component to act on the connecting pin, thereby controlling the connection state of the window sash and the slider.

[0012] Furthermore, the rotating component and the triggering component are connected by a hinge or a meshing connection; when a hinge is used, the rotating component is a rotating disk, the triggering component is a transmission rod, and one end of the transmission rod is connected to the eccentric point of the rotating disk through a hinge; when a meshing connection is used, the rotating component is a gear, the triggering component is a rack, and one end of the rack meshes with the gear.

[0013] Furthermore, the frame has a control component for controlling the connection state between the slider and the window sash. The control component includes a first push block for controlling the connecting pin on the first slider and a second push block for controlling the connecting pin on the second slider. The connecting pin has a guide slope, and under the action of the guide slope, the connecting pin can automatically connect when the window sash is closed. When the first push block and the second push block move, the connecting pin is pushed by the first push block and the second push block to achieve unified control of the connection state between the first slider and the window sash or between the second slider and the window sash.

[0014] Furthermore, the length directions of both the first push block and the second push block are parallel to the width direction of the frame. The contact surfaces of the first push block and the connecting pin, and the contact surfaces of the second push block and the connecting pin, are horizontally arranged so that the first and second sliders can slide on the first or second push block when moving. Each of the first and second push blocks is equipped with a control wheel, the rotation of which is controlled by the frame. Both the first and second push blocks are positioned at the eccentric points of the control wheels. The rotation of the control wheels drives the first and second push blocks to move up and down, thereby achieving the effect of moving the connecting pin via the first and second push blocks.

[0015] Furthermore, both ends of the first push block and the second push block are telescopic ends and are telescopically configured. The telescopic ends are vertically slidably configured on the frame. When the control wheel controls the first push block and the second push block to move, the first push block or the second push block can push the connecting pin in any position by means of the telescopic ends.

[0016] Furthermore, the frame is provided with a first slide rail and a second slide rail, the transmission direction of the first slide rail and the second slide rail is parallel to the width direction of the frame, the first push block is slidably disposed on the first slide rail, and the second push block is slidably disposed on the second slide rail; the movement of the first push block and the second push block is independently controlled by the first slide rail and the second slide rail.

[0017] Furthermore, a third slide rail is provided on the frame, the transmission direction of the third slide rail is parallel to the width direction of the frame, and the first push block and the second push block are both slidably disposed on the third slide rail; the first push block and the second push block are each equipped with an independent control motor, and the control motor controls the movement of the first push block or the second push block on the third slide rail.

[0018] The main technical effects of this invention are reflected in the following aspects:

[0019] This invention achieves dynamic switching of the folding direction of the window sash by setting selectively connectable slider structures at both ends of the window sash and combining them with an independently controlled pusher mechanism. When the user needs to open from the left, the control system drives the first pusher to establish a rotational connection between all window sashes and the left slider, while the right connection is automatically disconnected, and the window sashes fold to the left sequentially; conversely, it can switch to the right-side opening mode. This function breaks through the technical limitations of traditional folding sliding windows with fixed opening directions, allowing the same door-window system to adapt to different interior layouts. Especially in spaces near wall corners, densely furnished areas, or asymmetrical passageways, it allows for flexible selection of the unobstructed side for folding, avoiding obstructed opening and greatly improving space utilization and user experience.

[0020] This invention features a guide slope at the end of the connecting pin. When the window sash is fully closed, the slider automatically aligns with the connecting hole of the window sash. Guided by the guide slope, the connecting pin is compressed and retracted, then ejected by a spring and inserted into the slider hole, completing the automatic locking. This structure achieves reliable connection without additional drive, improving system safety and ease of operation. Simultaneously, combined with the push block's active lifting and disconnection mechanism, it forms an intelligent control logic of "automatic connection + manual / electric disconnection," ensuring a secure seal when the door and window are closed and safe unlocking before opening.

[0021] This invention features a third slide rail on the frame, shared by the first and second push blocks, each driven by an independently controlled motor. This design ensures structural compactness while achieving complete decoupling of control actions on both sides. The control system can precisely control the position of each push block on the slide rail according to instructions, and simultaneously lift the connecting pins on the corresponding sides via a lifting mechanism, completing the synchronous switching of the connection states of all window sashes. This design avoids the delays and errors caused by traditional point-to-point control, improving system response speed and operational stability, and is particularly suitable for large-scale door-and-window systems with a large number of window sashes and wide spans.

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0031] This invention provides a sliding door and window with a switchable opening side, aiming to solve the technical problems of existing folding sliding doors and windows, such as laborious operation, fixed opening direction, and limited functional modes. It is mainly applied in high-end residences, villas, sunrooms, scenic balconies, hotel suites with views, commercial exhibition spaces, and modern office buildings—buildings with high requirements for lighting, ventilation, visual transparency, and intelligent experience. In these application environments, users can flexibly choose the opening side (left or right) of the door and window according to the actual spatial layout, daily traffic flow, climate conditions, or aesthetic needs, avoiding opening obstacles caused by furniture obstruction, wall corners, or restricted passageways, and maximizing the use of indoor and outdoor transition space. However, this is not a limitation; it can also be used in other similar or identical manufacturing processes.

[0032] Example 1

[0033] See Figure 1 , Figure 2This embodiment discloses a sliding door-window with switchable opening sides, including a frame 1. The frame 1 has several window sashes 2 with sliding functions. Specifically, the frame 1 consists of a top guide rail, a bottom guide rail, and two side columns, forming a stable rectangular support structure. Multiple window sashes 2 are arranged horizontally side-by-side inside the frame 1. Each window sash 2 has a transparent glass panel and a lightweight aluminum alloy frame, ensuring overall structural strength while maintaining transparency and aesthetics. This configuration is typical of conventional sliding windows. Crucially, each window sash 2 has an independently controllable opening and closing component 3 at both the top and bottom in the height direction. This component 3 is the core mechanism for switching the opening direction and smooth sliding; that is, the window sash 2 has opening and closing components 3 at both ends in the height direction. The opening and closing component 3 includes a slider and a connecting rod. The slider is slidably mounted on the frame 1, installed within the top and bottom guide rails of the frame 1, and can move freely along the length of the guide rails. The sliders are detachably mounted at both ends of the window sash 2 in the width direction, allowing the sliders to selectively lock or release with the left or right end of the window sash 2. Specifically, the slider end is provided with an electromagnetic locking pin and a guide groove, and the window sash 2 end is correspondingly provided with a matching lock hole and a guide slope. When the slider moves to the designated position, the electromagnetic signal triggers the locking pin to act, realizing a quick connection or separation between the slider and the window sash 2. The entire process requires no manual intervention and can be completed only through control system commands. One end of the connecting rod is rotatably mounted on the slider, and the other end of the connecting rod is rotatably mounted in the middle area of ​​the window sash 2 (preferably near the geometric center of the window sash 2), forming a three-point linkage mechanism of "slider-connecting rod-window sash 2". This design allows the window sash 2 to not only achieve linear translation during sliding but also generate a slight rotational movement under the drive of the connecting rod, thereby automatically adjusting the angle when folding and closing, avoiding interference between window sashes 2 or between window sash 2 and the wall, and significantly improving the smoothness of the folding process and spatial adaptability. The sliding of the slider on the frame 1 enables the window sash 2 to slide on the frame 1. By controlling the connection and disconnection of the window sash 2 and the sliders on both sides, the window sash 2 on the frame 1 can be switched between opening and closing on one side (left or right). Traditional folding sliding windows, once installed, have a fixed closing direction, typically only able to fold to the left or right. In this embodiment, however, by controlling the connection state between the sliders on the left and right sides and the window sash 2, flexible switching of the opening direction can be achieved. For example, in the default state, all sliders are connected to the right side of the window sash 2, and the window sash 2 folds to the left. When the user needs to open it from the right, the control system automatically issues a command to disconnect the sliders corresponding to each window sash 2 from the current connection and relock them to the left side of the window sash 2. Subsequently, the sliders drive the window sash 2 to fold sequentially from the right side, achieving a rightward closing. This bidirectional switchable folding method greatly enhances the adaptability of the door-window system to different spatial layouts, and is especially suitable for installation environments near wall corners, furniture obstructions, or complex traffic flow.

[0034] See Figure 3 Furthermore, the mechanical structure of the opening and closing component 3 is optimized to achieve a 90-degree full opening and closing of the window sash 2 within the frame 1, and to support dynamic switching of the opening direction. Specifically, the slider and the window sash 2 can switch between a rotating connection and a disconnected state. The sliders located at both ends of the width direction of the window sash 2 are the first slider 31 and the second slider 32, respectively; the slider closer to the left side of the window sash 2 can be defined as the first slider 31, and the one closer to the right side as the second slider 32. Both sliders are slidably installed in the guide rails at the top and bottom of the frame 1 and can move freely along the entire length of the guide rails. The key improvement is that the first slider 31 and the second slider 32 are not fixedly connected to the window sash 2, but rather adopt a switchable rotating connection structure. That is, the slider and the end of the window sash 2 can quickly switch between the two states of "rotating connection" and "complete disconnection" through electromagnetic drive, mechanical locking, or pneumatic device. When the first slider 31 and the window sash 2 are rotatably connected, and the second slider 32 and the window sash 2 are disconnected, the first slider 31 becomes the driving fulcrum of the window sash 2. The window sash 2 is on the rotating side of the first slider 31, and on the free-moving side of the second slider 32, i.e., the opening / closing side. Conversely, when the first slider 31 and the window sash 2 are disconnected, and the second slider 32 and the window sash 2 are rotatably connected, the window sash 2 is on the rotating side of the second slider 32, and on the opening / closing side of the first slider 31. This bidirectional switchable connection method allows the same set of window sashes 2 to be folded or unfolded from the left or right side according to usage requirements, thereby achieving flexible adjustment of the opening direction.

[0035] A double-link cooperative system is introduced into the mechanical transmission structure. Specifically, the link is divided into a first link 33 and a second link 34 based on its connection with the first slider 31 and the second slider 32. The end of the first link 33 connected to the window sash 2 and the end of the second link 34 connected to the window sash 2 are rotatably connected together (using a coaxial rotational connection) and rotatably positioned in the middle of the window sash 2. That is, the ends of the two links are hinged together by a common pivot and are mounted as a whole on a mounting base near the geometric center or center of gravity of the window sash 2, forming a special structure of "double links converging at one point". This design brings significant kinematic advantages as follows: when a slider (such as the first slider 31) is connected to the window sash 2 and begins to slide along the guide rail, the window sash 2 will move in an arc around the connection point as the center of rotation due to the pushing or pulling action of the first link 33; at the same time, since the second slider 32 is disconnected from the window sash 2, the second link 34 only plays a guiding and auxiliary positioning role. As the slider continues to move, the angle of the connecting rod changes continuously, causing the window sash 2 to gradually rotate outward, ultimately achieving a maximum opening angle of 90 degrees relative to its original closed position. This 90-degree opening / closing state makes the window sash 2 completely perpendicular to the wall, greatly expanding the ventilation cross-section and effectively guiding outdoor airflow into the room, improving natural ventilation efficiency. The 90-degree opening and closing of the window sash 2 on the frame 1 is achieved through the cooperation of the first connecting rod 33, the second connecting rod 34, the first slider 31, and the second slider 32.

[0036] In actual operation, the system can automatically switch the opening direction according to a preset mode. For example, when opening from the left is required, the control system first issues a command to lock the first slider 31 of all window sashes 2 to the end of the window sash 2, while the second slider 32 is released and disconnected. Subsequently, the drive mechanism drives the first slider 31 to slide to the left, and the first connecting rod 33 pulls the window sash 2 to rotate around the left side, realizing the folding and opening process of unfolding one sash from the left. Conversely, if opening from the right is required, the system switches to the second slider 32 being connected and the first slider 31 being disconnected, the sliders move to the right, and the window sashes 2 unfold sequentially from the right.

[0037] See Figure 4 , Figure 5Furthermore, the control mechanism for the connection state between the window sash 2 and the slider is optimized. An opening / closing component 4 is proposed to automatically switch between a "rotational connection" and a "disconnected state" between the window sash 2 and the slider. Specifically: The window sash 2 has opening / closing components 4 on both sides in the width direction. These components control the connection state between the window sash 2 and the slider. Each component includes a rotating element 41, a trigger element 42, and a connecting pin 43. Both the window sash 2 and the slider have connecting holes 45. The connecting pin 43 acts on the connecting holes 45 to control the connection state between the window sash 2 and the slider. When the connecting pin 43 is inserted into the connecting holes 45 on both sides, the window sash 2 and the slider form a stable rotating joint connection, capable of transmitting motion and torque. When the connecting pin 43 is removed, the two are completely disengaged, and that end of the window sash 2 becomes a free end, no longer driven by the slider. The rotating component 41 is rotatably mounted on the window sash 2, and the trigger component 42 is slidably disposed on the window sash 2. One end of the trigger component 42 acts on the connecting pin 43, and the other end of the trigger component 42 is connected to the rotating component. By rotating the rotating component 41, the trigger component 42 is driven to act on the connecting pin 43, thereby realizing the control of the connection state between the window sash 2 and the slider.

[0038] The rotating component 41 and the trigger component 42 are connected by a hinge or meshing; this embodiment provides two preferred transmission connection methods to achieve efficient power transmission between the rotating component 41 and the trigger component 42:

[0039] The first implementation method is a hinged transmission structure. In this scheme, the rotating component 41 is a rotating disk (such as an eccentric wheel or a sector gear disk), and the trigger component 42 is a transmission rod. One end of the transmission rod is connected to the eccentric point of the rotating disk via a hinge; that is, the connection point is not at the rotation center of the rotating disk, but at a radial position on its edge. When an external drive signal (such as a motor, solenoid valve, or manual knob) causes the rotating disk to rotate, the rotation of the rotating disk is converted into the reciprocating linear motion of the transmission rod due to the eccentric setting of the connection point. For example, when the rotating disk rotates 90 degrees clockwise, the transmission rod is pulled inward, causing the connecting pin 43 to exit from the connecting hole 45, realizing the "disconnected" state; the reverse rotation pushes the connecting pin 43 into the hole, completing the "connected" action. This structure is simple, has a fast response, and is suitable for the interior of the window sash 2 frame where space is limited.

[0040] The second implementation method is a meshing transmission structure. In this scheme, the rotating component 41 is a gear, and the trigger component 42 is a rack. One end of the rack meshes with the gear. When the gear rotates under the action of a driving device (such as a micro stepper motor or an electromagnetic motor), the rotational motion is converted into the linear motion of the rack through the meshing transmission between the gear and the rack. The other end of the rack is connected to a pin 43, thereby controlling its extension and retraction. This structure has the advantages of high transmission accuracy, strong self-locking, and the ability to withstand large pushing and pulling forces. It is especially suitable for applications with large areas and heavy weights, ensuring the stability and safety of the connection action.

[0041] Both of the above structures can be integrated into the internal cavity of the aluminum alloy frame of the window sash 2 without compromising the overall appearance. The control system can independently control the opening and closing components 4 on the left and right sides of the window sash 2 according to user commands or preset programs. For example, when opening from the left, the system automatically controls the rotating part 41 of the right opening and closing component 4 to disengage the right connecting pin 43, disconnecting the window sash 2 from the second slider 32; simultaneously, it controls the connecting pin 43 of the left opening and closing component 4 to insert, achieving a rotational connection between the window sash 2 and the first slider 31. Subsequently, the drive mechanism drives the first slider 31 to slide along the guide rail, pulling the window sash 2 via the first connecting rod 33, folding and unfolding it to the right side, with the left side as the rotation side, ultimately achieving a full 90-degree opening. Conversely, if opening from the right is required, the left opening and closing component 4 disengages, the right connection is established, the slider moves to the right, and the window sash 2 unfolds from the right. This bidirectional switchable mechanism allows the same door and window system to adapt to different room layouts, furniture placements, or traffic habits, greatly improving the flexibility and user-friendliness of use. Additional information: Rotating component 41 is mainly a manual knob, used as a manual single-opening window sash 2.

[0042] See Figure 6 , Figure 7Furthermore, a unified control component 5 integrated on the frame 1 is introduced to achieve synchronous, efficient, and automated control of the connection status between multiple window sashes 2 and sliders. Specifically, the frame 1 has a control component 5 for controlling the connection status between the sliders and the window sashes 2. The control component 5 is located inside the top or bottom guide rail of the door-window frame 1 and extends along the width direction of the frame 1. The control component 5 includes a first push block 51 for controlling the connecting pin 43 on the first slider 31 and a second push block 52 for controlling the connecting pin 43 on the second slider 32. The connecting pin 43 has a guide slope 44, that is, its insertion end is a beveled or arc-shaped chamfered structure. When the window sash 2 is in the closed state and slides back to its original position along the guide rail, the connecting hole 45 on the slider aligns with the connecting hole 45 at the end of the window sash 2. Under the guidance of the guide slope 44, the connecting pin 43 is automatically retracted by the squeezing action of the slider sidewall, and then pops out under the action of the return spring, realizing automatic insertion and locking. This allows the system to automatically establish a connection when the window sash 2 is fully closed, without requiring additional driving action, thus improving operational convenience and safety. When the first push block 51 and the second push block 52 move, they push the connecting pin 43, achieving unified control over the connection state between the first slider 31 and the window sash 2, or between the second slider 32 and the window sash 2.

[0043] The length directions of the first push block 51 and the second push block 52 are both parallel to the width direction of the frame 1. The contact surfaces of the first push block 51 and the connecting pin 43, and the contact surfaces of the second push block 52 and the connecting pin 43, are horizontally arranged and perpendicular to the axis of the connecting pin 43. This allows the first slider 31 and the second slider 32 to slide on the first push block 51 or the second push block 52 during movement, avoiding jamming. More importantly, when disconnection is required, the control system is activated, driving the first push block 51 or the second push block 52 to move up and down. Its horizontal contact surface pushes up the connecting pin 43 on the corresponding side, overcoming the spring force and causing it to completely exit from the connecting hole 45 of the slider, thereby releasing the connection on that side.

[0044] Both the first push block 51 and the second push block 52 are equipped with control wheels 53. The rotation of the control wheels 53 is controlled by the frame 1. The first push block 51 and the second push block 52 are both located at the eccentric point of the control wheels 53. The rotation of the control wheels 53 drives the first push block 51 and the second push block 52 to move up and down, thereby achieving the effect of moving the connecting pin 43 via the first push block 51 and the second push block 52. By synchronously driving the control wheels 53, it can be ensured that the first push block 51 and the second push block 52 rise and fall evenly and synchronously along the entire length direction, thereby ensuring that the connecting pins 43 on the corresponding sides of all window sashes 2 are simultaneously lifted or released, achieving unified control of the connection status.

[0045] Furthermore, considering that the window sash 2 may be in any position on the guide rail during opening, traditional fixed push blocks are difficult to cover all connection points. Therefore, this embodiment optimizes the structure of the first push block 51 and the second push block 52: both ends of the first push block 51 and the second push block 52 are telescopic ends and are telescopically configured (the telescopic ends are vertically slidably configured on the frame 1 through guide grooves and elastic mechanisms (such as springs or hydraulic dampers)). When the control wheel 53 controls the first push block 51 and the second push block 52 to move, the first push block 51 or the second push block 52 can push the connecting pin 43 in any position due to the configuration of the telescopic ends.

[0046] In the actual workflow, the system operates as follows: Left-side opening mode switching: When the user selects "Fold Left," the control system drives the control wheel 53 to rotate, causing the second push block 52 to rise. Its horizontal contact surface lifts the connecting pins 43 on the right side of all window sashes 2, disconnecting the window sash 2 from the second slider 32. Simultaneously, the first push block 51 remains in a low position or releases synchronously, allowing the left-side connecting pins 43 to automatically insert through the guide slope 44 during the closing process of the window sash 2, establishing a left-side rotational connection. Subsequently, the drive mechanism starts, and the first slider 31 drives the window sash 2 to slide to the left and fold open. Right-side opening mode switching: Conversely, when "Fold Right" is selected, the first push block 51 rises, disconnecting the left-side connection; the second push block 52 moves to establish a right-side connection, the slider moves to the right, and the window sash 2 unfolds from the right side. Automatic reset and locking: When the window sash 2 is fully closed, the connecting pins 43 automatically insert into the corresponding slider's connecting hole 45 under the guidance of the guide slope 44. After the system confirms that the closure is in place, the push block falls back to the standby position, completing one operation cycle.

[0048] Based on Embodiment 1, this embodiment further optimizes the structure of the control component 5 on the frame 1. By setting an independent guide and transmission track system, independent, precise and stable control of the first push block 51 and the second push block 52 is achieved, thereby improving the reliability and operational flexibility of the entire door-window linkage during the opening side switching process.

[0049] Specifically, within the overall frame 1 of the door and window assembly (preferably a top guide rail or a bottom load-bearing guide rail), two independent sliding tracks are arranged parallel to each other along the width direction of the frame 1: a first sliding track and a second sliding track. Both tracks extend along the arrangement direction of the window sashes 2, passing through the installation areas of multiple window sashes 2, ensuring that the control range covers all opening and closing units. The first push blocks 51 are slidably mounted on the first sliding track, and the second push blocks 52 are slidably mounted on the second sliding track. Since the two tracks are independently arranged, the first push blocks 51 and the second push blocks 52 can slide independently within their respective tracks without interfering with each other, achieving complete decoupling of the connection state control on both sides. The first push blocks 51 on the first sliding track and the second push blocks 52 on the second sliding track can be driven simultaneously by a lead screw and a drive motor.

[0050] The movement of the first push block 51 and the second push block 52 is independently controlled by the first slide rail and the second slide rail. During operation, when the system needs to switch the opening side, for example, from the "left-side opening" mode to the "right-side opening" mode, the control system first drives the first push block 51 to move along the first slide rail to the position directly below the left connecting pin 43 of each window sash 2. Then, the eccentric wheel mechanism drives the first push block 51 to move upward, so that its horizontal contact surface lifts the left connecting pin 43, causing it to exit the connecting hole 45 of the first slider 31, thus completing the release of the left connection. At the same time, the second push block 52 moves under the guidance of the second slide rail to the position below the right connecting pin 43, and rises under the drive of the control wheel 53, lifting the right connecting pin 43, so that it automatically inserts into the connecting hole 45 of the second slider 32 under the action of the return spring, establishing a right rotational connection.

[0051] Example 3

[0052] See Figure 1 , Figure 2 Based on Embodiment 1, this embodiment further optimizes the structure of the control component 5 on frame 1, adopting an advanced layout of shared slide rails and independent drives, which significantly improves system integration, control flexibility, and response accuracy. Details are as follows:

[0053] A third slide rail 54 is provided on the frame 1. The transmission direction of the third slide rail 54 is parallel to the width direction of the frame 1. The first push block 51 and the second push block 52 are both slidably mounted on the third slide rail 54. The shared slide rail design not only reduces structural complexity and saves installation space, but also improves the overall rigidity and smoothness of the system, making it particularly suitable for modern minimalist door and window systems with limited frame space. Each of the first push block 51 and the second push block 52 is equipped with an independent control motor (such as a micro stepper motor or a DC servo motor). The motor is fixed to the frame 1 and connected to the corresponding push block via a transmission mechanism (such as a gear-rack, synchronous belt, or screw drive). Each control motor operates independently and can drive the first push block 51 or the second push block 52 to move freely along the length direction on the third slide rail 54, achieving precise position control. The movement of the first push block 51 or the second push block 52 on the third slide rail 54 is controlled by the control motor.

[0054] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
