Description

Technical Field

[0001] This utility model relates to a hand-electric integrated mechanical transmission lifting window. Background Technology

[0002] In existing technologies, hand-operated and electric-mechanically driven lift windows are widely used in building window lifting systems. In traditional lift window designs, the drive motor and transmission box are typically installed within the side frame of the window. This layout, to a certain extent, ensures the stability of the window and the normal operation of the transmission system. However, with increased usage time, traditionally designed lift windows often face maintenance difficulties. Because the installation location of the drive motor and transmission box is relatively concealed, when a malfunction occurs or maintenance is required, maintenance personnel have to disassemble the window to operate it. This not only increases the complexity of maintenance but also incurs additional time and labor costs.

[0003] Furthermore, traditional lift-up window designs lack convenient disassembly and maintenance methods. If the transmission system malfunctions, the entire window disassembly process is both cumbersome and time-consuming. Moreover, the chain mechanism and counterweight system in traditional designs do not adequately consider the window's balance and the system's long-term operational stability, further increasing the difficulty of maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a manual-electric integrated mechanical transmission lifting window, which can improve the maintenance convenience of the lifting window and the stability of the transmission system, and solve the problem of troublesome window disassembly and maintenance in traditional designs.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A hand-held electric motor integrated mechanical transmission lifting window includes a window body, a drive mechanism disposed in the middle of the window body, and chain mechanisms disposed on both sides of the window body. The drive mechanism includes a drive motor, a transmission box connected to the drive motor, a transmission rod that is linked with the transmission box, and a lifting gear disposed at the end of the transmission rod. Accommodation grooves are formed on both sides of the window body, and fixed chains that mesh with the lifting gears are disposed in the accommodation grooves. The chain mechanism includes a counterweight base and a lifting chain with one end connected to the counterweight base and the other end connected to the window body.

[0006] Preferably, the lifting chain is U-shaped and has a sprocket at the bend for limiting movement.

[0007] Preferably, a mounting base is provided outside the lifting gear, the transmission rod passes through the mounting base and the lifting gear, and forms a rotatable connection with the mounting base and a fixed connection with the lifting gear.

[0008] Preferably, the transmission box is located in the middle of the window, and the transmission rod is located at both ends of the transmission box.

[0009] Preferably, the fixed chain is fixedly connected to the receiving groove, which is located at the edge of both sides of the window and faces the transmission box.

[0010] Preferably, the counterweight base is provided with one or more counterweight blocks, and the outer periphery of the counterweight base is provided with sliding wheels.

[0011] The beneficial effects of this utility model are: Unlike traditional designs where the drive motor and transmission box are mounted on the side frame of the window, this invention centrally positions the drive motor and transmission box in the middle of the window, linking them with the transmission rod and lifting gear. This design not only simplifies the installation process but also makes the motor and transmission box easier to maintain. In case of malfunction or maintenance, the entire window does not need to be disassembled, making operation more convenient and faster, reducing maintenance time and costs. By providing receiving grooves on both sides of the window and installing fixed chains within these grooves, the meshing between the lifting gear and the chain is more stable, reducing chain misalignment or damage caused by prolonged use or external forces. This not only improves the system's operational stability but also extends its service life.

[0012] This solution achieves optimized mechanical balance through the design of a counterweight base and lifting chain. The counterweight base effectively adjusts the weight distribution of the window, ensuring uniform force during lifting, thereby improving lifting efficiency and reducing the risk of damage over long-term use. The layout of the drive mechanism, transmission box, and chain mechanism is concentrated in the middle and sides of the window, making the entire lifting window system more compact and reducing unnecessary space occupation. This compact structural design not only saves installation space but also enhances the simplicity of the window's appearance. The lifting window design of this invention is reasonable and easier to operate, facilitating installation and debugging. Furthermore, the system's stability and maintenance convenience are significantly improved during long-term use. This makes the lifting window more suitable for high-frequency usage scenarios in modern buildings, meeting the needs of saving space, reducing costs, and improving efficiency.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0017] See Figure 1-2 As shown, the integrated electric and mechanical transmission lifting window includes a window body 1, a drive mechanism 2 located in the middle of the window body 1, and chain mechanisms 3 located on both sides of the window body 1. The drive mechanism 2 includes a drive motor 21, a transmission box 22 connected to the drive motor 21, a transmission rod 23 that forms a linkage with the transmission box 22, and a lifting gear 24 located at the end of the transmission rod 23. The two sides of the window body 1 have receiving grooves 11, and a fixed chain 12 that meshes with the lifting gear 24 is provided in the receiving grooves 11. The chain mechanism 3 includes a counterweight base 31 and a lifting chain 32 with one end connected to the counterweight base 31 and the other end connected to the window body 1.

[0018] By placing the drive motor 21 and transmission box 22 in the middle of the window 1 and linking them with the transmission rod 23 and lifting gear 24, the complex structure of mounting the motor and transmission box 22 on the side frame in traditional designs is avoided. This layout makes the motor and transmission box 22 easier to access and maintain, and window 1 does not need to be disassembled during maintenance, reducing maintenance time and costs and improving operational convenience.

[0019] Fixed chains 12 that mesh with lifting gears 24 are installed in the receiving grooves 11 on both sides of the window 1. This design effectively reduces chain deviation or damage, ensures long-term stable meshing between the chain and gears, and improves the operational stability and durability of the window 1. This robust meshing structure reduces malfunctions caused by improper operation or long-term use, and extends service life. The fixed chain 12 can also be replaced with a rack and pinion structure, achieving the same effect.

[0020] Through the design of the counterweight base 31 and the lifting chain 32, the gravity distribution of the window 1 is effectively adjusted, ensuring mechanical balance during the lifting process. This optimized design makes the window 1 more evenly lifted, reducing wear caused by uneven force, improving system efficiency, and lowering the system failure rate.

[0021] The lifting chain 32 is U-shaped and has a sprocket at the bend for limiting; the lifting gear 24 is provided with a mounting base, the transmission rod 23 passes through the mounting base and the lifting gear 24, and is rotatably connected to the mounting base and fixedly connected to the lifting gear 24.

[0022] The lifting chain 32 is designed with a U-shaped bend, and a sprocket is installed at the bend for limiting. This design effectively prevents the chain from slipping or shifting during use, ensuring stable chain operation, and also reduces damage caused by excessive chain stretching or misalignment, thereby improving the safety and service life of the system.

[0023] The mounting base external to the lifting gear 24, and the rotatable connection between the transmission rod 23 and the mounting base, ensure the stability of the lifting gear 24 during operation. The fixed connection between the transmission rod 23 and the lifting gear 24 prevents the lifting gear 24 from loosening or shifting during operation, thereby ensuring the efficient operation of the transmission system and reducing failures caused by gear wear.

[0024] The transmission rod 23 passes through the mounting base and the lifting gear 24, forming a rotatable connection with the mounting base. This structure allows for better coordination among the various components in the transmission system, resulting in a smoother transmission process. Through this design, the lifting window system can operate stably under different working environments, enhancing the overall system reliability, improving operational smoothness, and reducing the occurrence of mechanical failures.

[0025] The transmission box 22 is located in the middle of the window 1, and the transmission rod 23 is located at both ends of the transmission box 22; the fixed chain 12 is fixedly connected to the receiving groove 11, the receiving groove 11 is located at the edge of both sides of the window 1 and faces the transmission box 22; the counterweight base 31 is provided with one or more counterweight blocks 311, and the outer periphery of the counterweight base 31 is provided with sliding wheels 312.

[0026] Positioning the transmission box 22 in the middle of the window 1 and placing the transmission rods 23 at both ends of the transmission box 22 helps to make the entire transmission system more balanced during operation. This structural layout can effectively distribute the load of the window 1, reduce mechanical imbalance caused by uneven weight distribution, thereby improving the operational stability of the system and avoiding excessive wear or failure.

[0027] The fixed chain 12 is fixedly connected to the receiving groove 11, which is located on both sides of the window 1 and faces the transmission box 22. This design makes the structure of the entire window 1 more compact and reasonable. This layout can effectively utilize the space on both sides of the window 1, while also simplifying the installation and maintenance process, making the whole device more efficient, space-saving, and helping to reduce external interference and mechanical impact.

[0028] The multiple counterweights 311 on the counterweight base 31 can be flexibly adjusted according to the weight requirements of the window 1, ensuring a more stable system during lifting and reducing offset or vibration caused by gravity imbalance. The sliding wheels 312 on the outer periphery can effectively reduce friction and ensure smooth movement of the counterweight base 31 within the window 1, thereby improving the operating efficiency and stability of the lifting window and reducing energy consumption.

[0029] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
