Abstract
Description
Technical Field
[0001] This application relates to the field of windows, and more particularly to a connecting bracket for an electrically operated lifting window. Background Technology
[0002] In modern architecture, motorized lifting window structures are widely used for the automatic opening and closing of windows. Their main function is to improve the convenience and safety of windows. However, traditional motorized lifting window structures often have limitations in design and material selection, which leads to uneven stress during use. This uneven stress not only affects the stability and safety of the window, but may also shorten the service life of the window and its related components.
[0003] In the existing technology, the connection between the chain and the window profile is usually fixed by screws or pins passing through the chain and the profile. This connection method seems effective in the initial use, but over time, the screws are prone to breakage when subjected to shear force, causing the window to lose stability. In addition, due to the limitations of the connection method, the window profile often exhibits uneven stress during the stress process, which not only increases the risk of deformation but also affects the overall safety of the window.
[0004] To address the aforementioned issues, existing technologies typically attempt to improve the stability and safety of the window by reinforcing the materials of connecting components or adding support points. However, these measures fail to fundamentally resolve the problems of uneven stress distribution and unstable chain lifting, and still present risks of window profile deformation and operational instability. Therefore, it is necessary to provide an electrically operated lifting window structure that can resolve uneven stress distribution on the window profile, thereby addressing the issue that the connecting components of existing electrically operated lifting window structures are prone to breakage due to large shear forces, leading to uneven stress distribution and deformation of the window profile. Utility Model Content
[0005] In view of this, it is necessary to provide a connecting bracket for an electric lifting window that distributes force evenly to solve the above problems.

[0007] A chain assembly connects the drive structure and the window.
[0008] A connecting bracket is provided between the chain assembly and the window. One end of the connecting bracket has a receiving groove. The groove body fits the outer contour of the chain assembly and is snap-fitted to the end of the chain assembly away from the drive structure. The other end of the connecting bracket is fixedly connected to the window.
[0009] In at least one embodiment of this application, the connecting bracket includes a plurality of fixing pins, and the vertical direction of the contact surface between the connecting bracket and the window is a first direction;
[0010] Viewed along the first direction, the connecting bracket has a first set of fixing holes, and the fixing pin passes through the first set of holes and the chain set, and is connected to the connecting bracket.
[0011] In at least one embodiment of this application, the direction perpendicular to both the first direction and the length direction of the chain group is the second direction;
[0012] The connecting bracket further includes a transmission end and a fixed end disposed away from the transmission end;
[0013] Viewed along the second direction, the transmission end has a receiving groove, the fixed end has a fixing groove, and the chain assembly can slide into the receiving groove along the second direction, and the window is fixed in the fixing groove.
[0014] In at least one embodiment of this application, the first fixing hole group is located on the transmission end, and the fixing end has a second fixing hole group that extends through a first direction.
[0015] A portion of the fixing pins passes through the first fixing hole group and the chain group, and is threadedly connected to the transmission end;
[0016] Another portion of the pin passes through the second fixing hole group and the window, and is threadedly connected to the fixing end.
[0017] In at least one embodiment of this application, when viewed along the first direction, the receiving groove is interference-fitted with the chain assembly, and the chain assembly abuts against the receiving groove in the length direction of the chain assembly.
[0018] In at least one embodiment of this application, the chain group includes a first chain and a second chain; viewed along the first direction, the first chain and the second chain are arranged in parallel, and both the first chain and the second chain are connected between the drive structure and the window.
[0019] In at least one embodiment of this application, the first chain includes;
[0020] A chain link, viewed along the first direction, has its chain links abutting against the receiving groove, and multiple chain links are connected end to end to form the first chain;
[0021] The receiving groove includes an abutting surface and a non-abutting surface that engage with the chain link. In the length direction of the chain assembly, the abutting surface engages with the chain link.
[0022] In at least one embodiment of this application, the chain link includes;
[0023] Two support plates arranged side by side along the length of the chain assembly and a column assembly connecting the two support plates;
[0024] Viewed along the second direction, the fixing pin passes through the non-adhesive surface and the column assembly and is threadedly connected to the connecting bracket.

[0029] The aforementioned connecting bracket for an electric lift window incorporates a connecting bracket structure as a support component. Simultaneously, the receiving groove of the connecting bracket conforms to the outer contour of the chain assembly, forming an anti-chain structure. This increases the stress points and contact area of the support component, significantly improving the uniformity of stress on the window frame. Unlike existing technologies that rely solely on screws or pins to connect the chain and window profile, one end of the connecting bracket is clamped to the chain assembly, while the other end is fixed to the window frame. This connection allows the connecting bracket to effectively bear the force transmitted by the chain and distribute it evenly across the window frame, thereby reducing the risk of concentrated local pressure. The presence of the connecting bracket also enhances the overall structural stability, reduces the possibility of connector breakage due to shear force, ensures smooth operation of the window during lifting and lowering, and extends its service life.

[0048] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0049] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component.

[0050] Embodiments of this application provide a connecting bracket for an electrically operated lifting window, including a drive structure and a window body connected thereto in a transmission manner. The connecting bracket for the electrically operated lifting window further includes:
[0051] A chain assembly connects the drive structure and the window.
[0052] A connecting bracket is connected between the chain assembly and the window, wherein one end of the connecting bracket is snap-fitted to the end of the chain assembly away from the drive structure, and the other end is fixedly connected to the window.
[0053] The aforementioned connecting bracket for electric lifting windows increases the number of stress points and contact area by incorporating this structure as a support component, significantly improving the uniformity of stress on the window frame. Unlike existing technologies that rely solely on screws or pins to connect the chain and window profile, one end of the connecting bracket is clamped to the chain assembly, while the other end is fixed to the window frame. This connection allows the connecting bracket to effectively bear the force transmitted by the chain and distribute it evenly across the window frame, thereby reducing the risk of concentrated local pressure. The presence of the connecting bracket also enhances the stability of the overall structure, reduces the possibility of connector breakage caused by shear forces, ensures smooth operation of the window frame during lifting and lowering, and extends its service life.
[0054] The following is in conjunction with the appendix Figures 1-16 The following describes some embodiments of this application in detail. Unless otherwise specified, the embodiments and features described below can be combined with each other.
[0055] This application provides a connecting bracket 100 for an electrically operated lifting window, including a drive structure 1, a window body 2, a chain assembly 3, and a connecting bracket 4. The drive structure 1 and the window body 2 are connected by a transmission connection; specifically, the transmission connection means that the drive element acts as a power source to drive the window body 2 to move. The chain assembly 3 is connected between the drive structure 1 and the window body 2. Specifically, in this embodiment, the chain assembly 3 serves as a connector to transmit the driving force of the drive structure 1 to the window body 2. The connecting bracket 4 is connected between the chain assembly 3 and the window body 2. Specifically, another connector is added between the chain assembly 3 and the window body 2. The connecting bracket 4 serves as a connector, with one end connected to the window body 2 and the other end connected to the chain assembly 3. By connecting to the chain assembly 3, it increases the stress point, which in turn disperses the force on the chain assembly 3 during the driving process, preventing the connecting end from being subjected to excessive stress during operation and causing the connector to break. In this embodiment, one end of the connecting bracket 4 is jammed to the end of the chain group 3 away from the drive structure 1, and the other end is fixedly connected to the window 2. In the dictionary, "jamming" usually refers to an obstacle or interruption in a process, especially a malfunction in the operation of machinery or equipment, which leads to the inability to operate normally. In this embodiment, jamming specifically emphasizes an obstacle process, that is, the connecting bracket can play a limiting role for the chain group.
[0056] Furthermore, the connecting bracket 4 includes multiple fixing pins 5. The perpendicular direction of the contact surface between the connecting bracket 4 and the window 2 is a first direction 6. Viewed along the first direction 6, the connecting bracket 4 has a first fixing hole group 7, and the fixing pins 5 pass through the first hole group and the chain group 3. The fixing pins 5 are connected to the connecting bracket 4. Specifically, in this embodiment, by the fixing pins 5 passing through the connecting bracket 4 and the chain group 3 located within the connecting bracket 4, the chain group 3 is fixed within the connecting bracket 4 in the first direction 6, reducing the vibration of the chain group 3 under external force and enabling the window 2 to remain stable when driven.
[0057] Furthermore, the directions perpendicular to the first direction 6 and the length direction of the chain assembly 3 are respectively designated as the second direction 8. The connecting bracket 4 also includes a transmission end 9 and a fixed end 10 disposed away from the transmission end 9. Viewed along the second direction 8, the transmission end 9 has a receiving groove 11, the fixed end 10 has a fixing groove 12, and the chain assembly 3 can slide into the receiving groove 11 along the second direction 8. Specifically, the assembly process of the chain assembly 3 is described, in which it can slide into the receiving groove 11 along the second direction 8, and the window 2 is fixed in the fixing groove 12.
[0058] Furthermore, the first set of fixing holes 7 is located on the driving end 9, and the fixed end 10 is provided with a second set of fixing holes 13 penetrating along the first direction 6. A part of the fixing pins 5 penetrate through the first set of fixing holes 7 and the chain group 3 and are threadedly connected to the driving end 9. Another part of the pins penetrate through the second set of fixing holes 13 and the window body 2 and are threadedly connected to the fixed end 10. Specifically, the specific fixing method of the chain group 3 and the window body 2 along the first direction 6 is described. Similarly, the purpose is to make the connection in the whole driving process closer and reduce shaking, so that the actuating process of the window body 2 is smoother.
[0059] In at least one embodiment of the present application, when observed along the first direction 6, the inner wall of the receiving groove 11 fits the outer contour of the chain group 3 and is in interference fit with the chain group 3. Specifically, the upper mating surface of the connecting bracket 4 is consistent with the outer contour of the chain and is in a wavy chain-like shape, so that the force-bearing contact area is larger and the force is more uniform, making the chain move more smoothly during the up-and-down lifting movement and the electric window operate more smoothly. And in the length direction of the chain group 3, the chain group 3 abuts against the receiving groove 11. Specifically, in the "Ci Hai" (Chinese dictionary), the meaning of "abut" is: the basic meaning of this character is "resist" or "withstand", and its extended meaning refers to offsetting or reducing a certain quantity, amount, etc.; "deduct" usually means "deduct" or "subtract", and can also mean removing something from the whole. Combined together, "abut" means subtracting a certain part of the amount or quantity when calculating the total amount, so that the final result is reduced. In this embodiment, "abut" refers to a connection relationship, similar to limiting. That is, in the length direction of the chain group 3, the receiving groove 11 plays a limiting role on the chain group 3. Combining the definition of "abut", it means that the receiving groove 11 abuts against the chain group 3 to play a buckling limiting role on the chain group 3. The purpose is to increase the force-bearing area through the abutment between the receiving groove 11 and the chain group 3 surface by surface, making the force more uniform, and more specifically explaining the reason why the chain moves more smoothly during the up-and-down lifting movement.
[0060] Furthermore, the chain group 3 includes a first chain 14 and a second chain 15. When observed along the first direction 6, the first chain 14 and the second chain 15 are arranged in parallel, and both the first chain 14 and the second chain 15 are connected between the driving structure 1 and the window body 2. Specifically, the setting of multiple chains enables the chain group 3 to carry a window body 2 with a greater weight.
[0061] Furthermore, the first chain 14 includes chain links 16. Viewed along the first direction 6, the chain links 16 abut against the receiving groove 11. Multiple chain links 16 are connected end-to-end to form the first chain 14. This multi-link structure further distributes the shear force acting on the chain across multiple chain links 16, which is why the chain assembly 3 can withstand greater shear force. The receiving groove 11 includes abutting surfaces 22 and non-butting surfaces 20 that abut against the chain links 16. Specifically, the introduction of the features of the abutting surfaces 22 and 20 provides a more detailed explanation of more uniform force distribution compared to the receiving groove 11. In the length direction of the chain assembly 3, the abutting surfaces 22 abut against the chain links 16. In this embodiment, the principle of uniform force distribution in the chain assembly 3 is the abutting, i.e., the chain assembly 3 abuts against the receiving groove 11. Specifically, the chain assembly 3 can be decomposed into multiple interconnected chain links. 16. The receiving groove 11 can also be decomposed into a retaining surface 22 and a non-retaining surface 20. That is, the principle of uniform force on the chain group 3 can be further understood as the chain link 16 abutting against the retaining surface 22 of the receiving groove 11, which plays a limiting role in its direction of movement. Since it is a surface-to-surface contact, the contact surface is much larger than the contact surface with a line or a point. According to the pressure distribution theory, when the contact surface increases, the force applied to the surface is distributed to a larger area, thereby reducing the pressure per unit area and resulting in more uniform force.
[0062] Furthermore, the chain link 16 includes a column assembly 19 and a support plate 18, the support plates 18 being arranged side-by-side along the length of the chain assembly 3. The column assembly 19 is connected between two support plates 18. Viewed along the second direction 8, the fixing pin 5 penetrates the non-adhesive surface 20 and the column assembly 19. Specifically, the fixing pin 5 is positioned to avoid interfering with the chain assembly 3's engagement process, serving only to fix the chain assembly 3 horizontally, without being subjected to vertical shearing forces. The fixing pin 5 is threadedly connected to the connecting bracket 4.
[0063] Furthermore, the column assembly 19 and the two support plates 18 form the inner wall of the chain link 17. The fixing pin 5 passes through the chain link 17 along the first direction 6 and is threadedly connected to the connecting bracket 4. Viewed along the length of the chain assembly 3, the fixing pin 5 abuts against the inner wall 21 of the chain link. Viewed along the first direction 6, there is a gap between the fixing pin 5 and the inner wall of the chain link 17. Specifically, the reason why the fixing pin 5 is only used to fix the chain assembly 3 in the horizontal direction and is not subjected to shear force in the vertical direction is that, in terms of position, there is a gap between the fixing pin 5 and the chain assembly 3 in the force direction of the chain assembly 3, but in the assembly direction of the chain assembly 3, it abuts against the chain assembly 3, causing the chain assembly 3 not to exert force on the fixing pin 5 in the actuation direction. In the assembly direction, i.e., the second direction 8, the fixing pin 5 fixes the chain assembly 3 to the connecting bracket 4.
[0064] Furthermore, the connecting bracket 4 is a one-piece molded aluminum block. Specifically, the one-piece molded aluminum block design significantly improves the strength and durability of the structure. By using aluminum material, the connecting bracket 4 not only has the advantage of being lightweight, but also has excellent corrosion resistance, making it suitable for various climatic conditions. Moreover, this one-piece molded design eliminates redundant welding and connection points in traditional connection methods, reducing potential failure points and enhancing overall stability. In the application scenario of lifting the window 2, this design can effectively extend the service life and reduce maintenance costs, ensuring the safety and reliability of the electric lifting window 2 in long-term use.
[0065] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
