Description

TECHNICAL FIELD

[0001] The utility model relates to door and window technical field especially relates to a door and window automatic inner structure and door and window. BACKGROUND

[0002] In modern architectural design, the inner door and window are widely used in residential, office and various public buildings due to its unique ventilation function and safety protection performance. The design of this kind of door and window aims to realize the natural circulation of indoor air through the inner opening mode, and effectively prevent children from falling accidentally, thereby improving the safety and comfort of living and working environment.

[0003] At present, the main opening modes of the inner door and window on the market are mainly divided into two categories: manual and electric. The manual opening mechanism relies on the direct force of the operator, and usually requires the user to rotate the handle on the door and window to the preset position. This action triggers the movement of the transmission assembly, and then drives the hinge assembly to change to the inner state. Subsequently, the operator needs to apply additional force to smoothly pull the door and window to the fully inner state. This process is not only complicated to operate, but especially for the elderly, children or people with limited physical strength, it may be particularly inconvenient. In addition, the accuracy and force control of manual operation is also one of the key factors affecting whether the door and window can be smoothly inverted.

[0004] In contrast, the electric opening mode aims to simplify the operation process and improve user experience through motor drive. However, the existing electric inner door and window faces a significant challenge in the implementation process: when the motor drives the door and window to switch from the closed state to the inner state, it needs to provide a considerable driving force to ensure the smooth completion of the action. This is because the weight of the door and window itself, the frictional resistance and the mechanical resistance in the hinge conversion process jointly act to increase the driving force requirement. If the motor driving force is insufficient, it may cause the door and window to fail to enter the inner state smoothly, or even damage the transmission mechanism, affecting the reliability and service life of the product. Therefore, how to effectively control energy consumption and cost while ensuring sufficient driving force has become a technical problem in the design of electric inner door and window.

[0005] In summary, whether it is a manual or electric opening mode, the existing inner door and window has certain limitations in terms of operation convenience, driving force requirement and energy efficiency management, and there is an urgent need for a more efficient, convenient and reliable solution to meet market demand.

In addition, by opening and closing the drive rocker arm and the short rocker arm, the force required in the driving process is effectively distributed. When the transmission component is driven away from the end of the short rocker arm, the sliding of the sliding part on the base causes the hinge component to separate from the transmission component and enter the tilting state. The driving force required for this process is reasonably distributed, reducing the requirements for motor or manual operation force. Conversely, during the retraction process, the closing action of the drive rocker arm and the short rocker arm assists the transmission component in pulling the hinge component back to its original position, which also reduces the force consumption.

[0037] See Figures 1 to 6 The specific embodiment shown discloses an automatic tilt-in structure for doors and windows, including: a hinge assembly 10, a transmission assembly 20, a base 30, a drive rocker arm 40, and a short rocker arm 50. The transmission assembly 20 is rotatably connected to the base 30. One end of the drive rocker arm 40 is rotatably connected to the transmission assembly 20, and the other end is rotatably connected to the hinge assembly 10. One end of the short rocker arm 50 is rotatably connected to the base 30, and the other end is rotatably connected to the hinge assembly 10. A sliding member 111 is connected to the hinge assembly 10, and the sliding member 111 is slidably connected to the base 30. The drive rocker arm 40 is provided with a drive groove 41, and the middle section of the hinge assembly 10 is provided with a drive shaft 112 corresponding to the drive groove 41. The drive shaft 112 is slidably connected to the drive groove 41.

[0038] Specifically, by designing the sliding connection of the transmission component 20 on the base 30, and the ingenious cooperation between the drive rocker arm 40 and the short rocker arm 50 with the transmission component 20 and the hinge component 10, the automatic tilting and retraction functions of the doors and windows are realized. Users do not need to exert effort to rotate the handle and pull the doors and windows like traditional manual tilting doors and windows, nor do they need to worry about insufficient driving force in the electric opening method. This innovative design greatly simplifies the operation process and improves the user experience, especially for people with limited strength, making it more user-friendly and convenient. Furthermore, by opening and closing the drive rocker arm 40 and the short rocker arm 50, the force required during the driving process is effectively distributed. When the transmission component 20 is driven away from the end of the short rocker arm 50, the sliding member 111 on the base 30 causes the hinge assembly 10 to separate from the transmission component 20 and enter the tilt-in state. The driving force required for this process is reasonably distributed, reducing the requirements for motor or manual operation. Conversely, during the retraction process, the closing action of the drive rocker arm 40 and the short rocker arm 50 assists the transmission component 20 in pulling the hinge assembly 10 back to its original position, similarly reducing force consumption. In addition, since the automatic tilt-in and retraction of the door and window are realized, the user does not need to directly contact the moving parts of the door and window, thereby reducing the safety risks during operation. Especially for children, this design can effectively prevent accidental injuries caused by misoperation. Furthermore, due to the versatility and flexibility of its design principle, this automatic tilt-in structure can be widely used in different types of door and window systems, including but not limited to wooden doors and windows, aluminum alloy doors and windows, and PVC doors and windows, providing architects and users with more choices and customization space.

[0039] More specifically, see Figures 1 to 2 In the first embodiment shown, when the transmission assembly 20 is pushed or pulled, the drive rocker arm 40 rotates accordingly, thereby causing the drive groove 41 on it to move. Due to the sliding connection between the drive shaft 112 and the drive groove 41, the hinge assembly 10 can respond to this displacement and move along a predetermined path. This linkage mechanism ensures the smoothness and reliability of the door and window during the tilting and retraction process.

[0040] In other words, the sliding connection between the drive groove 41 and the drive shaft 112 achieves efficient transmission between the transmission assembly 20 and the hinge assembly 10. This design not only reduces energy loss during transmission but also improves the response speed and accuracy of the movement. Furthermore, the coordinated design of the drive groove 41 and the drive shaft 112 helps reduce swaying and instability during transmission. This enhanced stability is crucial for improving the durability and extending the service life of doors and windows. Moreover, compared to traditional complex transmission mechanisms, the sliding connection between the drive groove 41 and the drive shaft 112 simplifies and optimizes the structure, reducing manufacturing costs and improving the overall performance and reliability of the product. Additionally, the versatility and flexibility of the drive groove 41 and drive shaft 112 design allow them to adapt to different types of door and window systems and installation environments. This enhanced adaptability provides architects and users with more choices and customization options.

[0041] See Figures 1 to 4 As shown, in one embodiment, the transmission component 20 is slidably connected to the lower part of the base 30, the base 30 is provided with an elongated groove 31, and the sliding member 111 is slidably connected to the elongated groove 31.

[0042] Specifically, one end of the hinge assembly 10 is slidably connected to the elongated groove 31 via a slider 111, allowing the hinge assembly 10 to slide back and forth along the elongated groove 31. When the hinge assembly 10 is separated from the transmission assembly 20, the slider 111 is located at the rightmost side of the elongated groove 31; when the hinge assembly 10 is closed with the transmission assembly 20, the slider 111 is located at the leftmost side of the elongated groove 31. That is, when the transmission assembly 20 is pushed away from the short rocker arm 50, it causes the hinge assembly 10 to begin sliding to the right along the elongated groove 31 through its linkage with the drive rocker arm 40. As the sliding continues, the hinge assembly 10 gradually separates from the transmission assembly 20 until the slider 111 reaches the rightmost side of the elongated groove 31. At this point, the door and window are in a fully tilted-in position. Conversely, when the transmission assembly 20 is pulled closer to the short rocker arm 50, it guides the hinge assembly 10 to begin sliding to the left along the elongated groove 31 through its linkage with the drive rocker arm 40. As the sliding continues, the hinge assembly 10 gradually closes with the transmission assembly 20 until the sliding member 111 reaches the leftmost side of the elongated groove 31. At this point, the door and window return to the closed state.

[0043] More specifically, the precise guidance of the sliding member 111 via the elongated groove 31 enables strict control over the movement path of the hinge assembly 10. This not only ensures the smoothness of the door and window during tilting and retraction but also improves the accuracy and reliability of the operation. Furthermore, designing the transmission assembly 20 below the base 30 and connecting it to the sliding member 111 via the elongated groove 31 makes the entire structure more compact. This design not only saves space but also enhances the overall aesthetics and ease of installation. In addition, the guiding function of the elongated groove 31 extends beyond path control; it also reduces the swaying of the hinge assembly 10 during movement, enhancing structural stability. This is crucial for improving the durability and extending the service life of the door and window. Moreover, the sliding connection and the design of the elongated groove 31 simplify the tilting and retraction process, allowing users to easily switch between door and window states without complex operations or excessive force.

[0044] See Figures 1 to 2 In the first embodiment shown, the drive groove 41 is also provided with a bayonet position 411 at one end near the transmission component 20. When the drive shaft 112 moves to the bayonet position 411, the hinge component 10 separates from the transmission component 20 and is in an inward tilting state.

[0045] Specifically, when the drive shaft 112 moves to the end away from the latch position 411, the hinge assembly 10 and the transmission assembly 20 close, and the door / window enters the retracted state. The latch position 411 acts as a limit, preventing the drive shaft 112 from sliding along the drive groove 41. That is, the latch position 411 is precisely set at a predetermined position in the drive groove 41, and its shape and size are carefully designed to ensure a perfect fit with the drive shaft 112. When the transmission assembly 20 is pushed or pulled, the drive rocker arm 40 rotates accordingly, causing the drive groove 41 and the drive shaft 112 therein to move. When the drive shaft 112 moves to the latch position 411, due to the limiting effect of the latch position 411, the drive shaft 112 cannot continue to slide along the drive groove 41. At this time, the hinge assembly 10 separates from the transmission assembly 20, and the door / window enters the tilt-in state. Conversely, when the door / window needs to return to the retracted state, the transmission assembly 20 is pushed or pulled in the opposite direction, the drive rocker arm 40 rotates, and the drive groove 41 moves in the opposite direction. At this time, the drive shaft 112 gradually slides out from the bayonet position 411 and moves along the drive groove 41 to the end away from the bayonet position 411. When the drive shaft 112 moves to that end, the hinge assembly 10 and the transmission assembly 20 close, and the door and window return to the closed state.

[0046] More specifically, the design of the latch 411 allows the drive shaft 112 to precisely stop at a predetermined position during sliding, thereby achieving accurate separation and closing between the hinge assembly 10 and the transmission assembly 20. This precise limiting function is of great significance for improving the reliability and stability of the inward tilting and retraction actions of the doors and windows. Furthermore, due to the limiting effect of the latch 411, the drive shaft 112 will not exceed the predetermined range during sliding, thus avoiding the risk of damage to doors and windows or personal injury caused by misoperation or external interference. This enhanced safety provides users with a more reassuring user experience. In addition, the cooperative design of the latch 411 and the drive shaft 112 achieves efficient transmission between the transmission assembly 20 and the hinge assembly 10. This design reduces energy loss and frictional resistance during transmission, improving the response speed and accuracy of the action. Moreover, users do not need to perform complex operations or judgments; they can simply push or pull the transmission assembly 20 to switch between the inward tilting and retraction states of the doors and windows. This simplified operation process improves user convenience and satisfaction.

[0047] See Figures 3 to 4 In the second embodiment shown, the hinge assembly 10 is provided with a drive groove 41, and the drive rocker arm 40 is provided with a drive shaft 112 corresponding to the drive groove 41. The drive shaft 112 is slidably connected to the drive groove 41.

[0048] Specifically, when the transmission component 20 is pushed or pulled, it causes the drive shaft 112 to slide in the drive groove 41 through linkage with the drive rocker arm 40. This sliding action not only realizes the power transmission between the transmission component 20 and the hinge component 10, but also ensures the smoothness and reliability of the door and window during the tilting and retraction process.

[0049] More specifically, the sliding connection between the drive groove 41 and the drive shaft 112 achieves efficient transmission between the drive rocker arm 40 and the hinge assembly 10. This design reduces energy loss and frictional resistance during transmission, improving the response speed and accuracy of the action, allowing the doors and windows to quickly and accurately switch to the tilt-in or retracted state. Furthermore, compared to traditional complex transmission mechanisms, the sliding connection between the drive groove 41 and the drive shaft 112 simplifies and optimizes the structure, reducing manufacturing costs and improving the overall performance and reliability of the product, making the doors and windows more aesthetically pleasing and durable. Additionally, the coordinated design of the drive groove 41 and the drive shaft 112 helps reduce swaying and instability during transmission. This enhanced stability is crucial for improving the durability and extending the service life of doors and windows, while also providing users with a safer and more reliable user experience. Moreover, the versatility and flexibility of the drive groove 41 and drive shaft 112 design allow them to adapt to different types of door and window systems and installation environments. This enhanced adaptability provides architects and users with more choices and customization options, making door and window designs more diverse and personalized.

[0050] See Figures 3 to 4 In the second embodiment shown, the drive groove 41 is also provided with a locking position 411 at one end near the sliding member 111. When the drive shaft 112 moves to the locking position 411, the hinge assembly 10 separates from the transmission assembly 20 and is in an inward tilting state.

[0051] Specifically, when the drive shaft 112 moves to the end away from the latch position 411, the hinge assembly 10 and the transmission assembly 20 close and are in a retracted state. The latch position 411 acts as a limit to prevent the drive shaft 112 from sliding along the drive groove 41. That is, when the transmission assembly 20 is pushed or pulled, it causes the drive shaft 112 to slide within the drive groove 41 through its linkage with the drive rocker arm 40. When the drive shaft 112 moves to the latch position 411, due to the limiting effect of the latch position 411, the drive shaft 112 cannot continue to slide along the drive groove 41. At this time, the hinge assembly 10 and the transmission assembly 20 separate, and the door and window enter the inward tilting state. Conversely, when the door and window need to return to the retracted state, the transmission assembly 20 is pushed or pulled in the opposite direction, the drive shaft 112 gradually slides out from the latch position 411 and moves along the drive groove 41 to the end away from the latch position 411. When the drive shaft 112 moves to that end, the hinge assembly 10 and the transmission assembly 20 close again, and the door and window return to the closed state.

[0052] More specifically, the design of the latch 411 allows the drive shaft 112 to precisely stop at a predetermined position during sliding, thereby achieving accurate separation and closing between the hinge assembly 10 and the transmission assembly 20. This precise limiting function is of great significance for improving the reliability and stability of the inward tilting and retraction actions of the doors and windows, avoiding the risk of damage to doors and windows or personal injury caused by misoperation or external interference. In addition, the cooperative design of the latch 411 and the drive shaft 112 achieves efficient transmission between the transmission assembly 20 and the hinge assembly 10. This design reduces energy loss and frictional resistance during transmission, improves the response speed and accuracy of the action, and allows the doors and windows to quickly and accurately switch to the inward tilting or retraction state. Furthermore, the limiting function of the latch 411 not only ensures the accuracy of the inward tilting and retraction actions of the doors and windows, but also improves the safety of the product; since the drive shaft 112 will not exceed the predetermined range during sliding, the risk of damage to doors and windows or personal injury caused by excessive movement is avoided. In addition, users do not need to perform complicated operations or judgments. They can simply push or pull the transmission component 20 to switch between the inward tilting and retracting states of the doors and windows. This simplified operation process improves the user's convenience and satisfaction.

[0053] See Figures 5 to 6 As shown, in one embodiment, both the drive groove 41 and the drive shaft 112 are located at an off-center position along the centerline of the length direction of the hinge assembly 10.

[0054] Specifically, by placing the drive groove 41 and drive shaft 112 in an eccentric position, the driving force required for tilting inward can be reduced using mechanical principles. This design allows the drive shaft 112 to slide more smoothly within the drive groove 41 during the tilting process, requiring less external force and thus improving the product's ease of use and user experience. Furthermore, the eccentric position design also helps improve the stability of the door / window during tilting inward; because the positions of the drive shaft 112 and drive groove 41 are carefully calculated and optimized, they provide better mechanical balance during tilting, reducing swaying and instability, thereby improving the product's durability and safety. Additionally, placing the drive groove 41 and drive shaft 112 in an eccentric position optimizes the product's spatial layout. This design makes the door / window structure more compact, reducing unnecessary space occupation and providing users with a more spacious and comfortable environment. Moreover, because this eccentric position design has a certain degree of versatility and flexibility, it can adapt to different types of door / window systems and installation environments. This enhanced adaptability provides architects and users with more choices and customization options, making door / window designs more diverse and personalized.

[0055] See Figures 1 to 6As shown, in one embodiment, the transmission assembly 20 includes a drive rod 21 and a pin 22. The drive rod 21 is slidably connected to the lower part of the base 30. The drive rod 21, the pin 22, and the drive rocker arm 40 are connected by a transmission shaft 23. The end of the pin 22 away from the drive rod 21 is provided with a locking protrusion 221. The hinge assembly 10 is provided with a lock seat 121. The lock seat 121 is provided with a lock groove (not shown in the figure) for the locking protrusion 221 to be inserted.

[0056] Specifically, after the hinge assembly 10 and the transmission assembly 20 are closed, the transmission assembly 20 continues to move towards one end near the short rocker arm 50, causing the locking protrusion 221 to insert into the locking groove to achieve a locking effect. In other words, the drive rod 21 is designed to slide along the base 30. This sliding connection allows the drive rod 21 to move smoothly under external force, thereby driving the movement of the entire transmission assembly 20. The drive rod 21 is connected to the pin 22 and the drive rocker arm 40 via the transmission shaft 23. This connection ensures that the pin 22 and the drive rocker arm 40 move synchronously with the drive rod 21. When the transmission assembly 20 slides along the base 30 under the action of driving force, driving the drive rod 21 and the pin 22 to move, the locking protrusion 221 of the pin 22 gradually approaches the lock seat 121 of the hinge assembly 10. When the hinge assembly 10 and the transmission assembly 20 are fully closed, the transmission assembly 20 will continue to move towards one end of the short rocker arm 50 (i.e., continue to slide a certain distance). At this time, the locking protrusion 221 will be accurately inserted into the lock groove, thereby realizing the locking function of the door and window.

[0057] More specifically, by designing the locking protrusion 221 of the latch 22 and the lock seat 121 and lock groove of the hinge assembly 10, reliable locking of the door and window in the retracted state is achieved. This locking method is not only simple in structure and easy to implement, but also has a stable and reliable locking effect, effectively preventing the risk of the door and window being accidentally opened due to external forces. In addition, the drive rod 21, the latch 22, and the drive rocker arm 40 are connected by the transmission shaft 23, forming a compact and efficient transmission system. This design not only reduces energy loss during transmission, but also improves the response speed and accuracy of the action, enabling the door and window to quickly and accurately achieve the locking function. Furthermore, due to the cooperation between the locking protrusion 221 and the lock groove, the door and window have stronger wind pressure resistance and anti-theft performance in the locked state. This design not only improves the safety of the product, but also provides users with a more secure and comfortable user experience.

[0058] See Figures 1 to 6 As shown, in one embodiment, the hinge assembly 10 includes a long rocker arm 11 and a hinge end 12, the slider 111 is disposed at the end of the long rocker arm 11 away from the hinge end 12, and the lock seat 121 is disposed at the hinge end 12.

[0059] Specifically, the drive shaft 112 or drive groove 41 is located in the middle section of the long rocker arm 11. This position is chosen to balance transmission efficiency and structural compactness. The middle position of the drive shaft 112 or drive groove 41 allows the transmission assembly 20 to maintain good mechanical balance when driving the door and window sash to tilt inward and retract, while avoiding unnecessary interference with other parts of the long rocker arm 11.

[0060] More specifically, by positioning the slider 111 at the end of the long rocker arm 11 away from the hinge end 12, and positioning the drive shaft 112 or drive groove 41 in the middle section of the long rocker arm 11, the connection method and transmission path between the transmission assembly 20 and the hinge assembly 10 are optimized. This design reduces energy loss and frictional resistance during transmission, and improves the response speed and accuracy of the action. Furthermore, the carefully designed positions of the slider 111, lock seat 121, and drive shaft 112 or drive groove 41 make the hinge assembly 10 more compact. This compactness not only reduces the product's size and weight but also improves its overall performance and reliability. Additionally, the lock seat 121 is positioned on the hinge end 12, opposite the long rocker arm 11, allowing the locking protrusion 221 of the latch 22 to be accurately inserted. This design ensures that the door and window can be reliably locked in the retracted state, preventing the risk of accidental opening due to external forces. In addition, the fact that the drive shaft 112 or drive groove 41 is in the middle position allows the transmission assembly 20 to maintain good mechanical balance when driving the door and window sash to tilt inward and retract. This balance reduces the shaking and instability of the door and window sash during operation, and improves the durability and safety of the product.

[0061] In one embodiment, there are two drive shafts 112, which are arranged side by side.

[0062] Specifically, the two drive shafts 112 are arranged side by side, which can improve the stability of the drive.

[0063] The hinge end 12 adopts existing publicly available technology, which will not be elaborated on here.

[0064] This utility model also discloses a door and window, including the automatic tilt-in structure of the door and window as described above.

[0065] Specifically, by designing the sliding connection of the transmission component 20 on the base 30, and the ingenious cooperation between the drive rocker arm 40 and the short rocker arm 50 with the transmission component 20 and the hinge component 10, the automatic tilting and retraction functions of the doors and windows are realized. Users do not need to exert effort to rotate the handle and pull the doors and windows like traditional manual tilting doors and windows, nor do they need to worry about insufficient driving force in the electric opening method. This innovative design greatly simplifies the operation process and improves the user experience, especially for people with limited strength, making it more user-friendly and convenient. Furthermore, by opening and closing the drive rocker arm 40 and the short rocker arm 50, the force required during the driving process is effectively distributed. When the transmission component 20 is driven away from the end of the short rocker arm 50, the sliding member 111 on the base 30 causes the hinge assembly 10 to separate from the transmission component 20, entering the tilt-in state. The driving force required for this process is reasonably distributed, reducing the force required for motor or manual operation. Conversely, during the retraction process, the closing action of the drive rocker arm 40 and the short rocker arm 50 assists the transmission component 20 in pulling the hinge assembly 10 back to its original position, similarly reducing force consumption. In addition, since the automatic tilt-in and retraction of the doors and windows are realized, users do not need to directly contact the moving parts of the doors and windows, thereby reducing the safety risks during operation. Especially for children, this design can effectively prevent accidental injuries caused by misoperation.

[0066] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
