Description

Technical Field

[0001] This utility model relates to the field of lifting window technology, specifically a lifting window structure driven by a top rod. Background Technology

[0002] A retractable window is a type of window that can be opened and closed, typically consisting of two parts: an upper and a lower section. It is opened and closed by moving the upper and lower sections, usually manually operated or controlled by an electric motor. Retractable windows are commonly used in buildings and are designed to facilitate ventilation and lighting. These windows are generally more convenient than traditional sliding windows because their opening and closing is easier to control.

[0003] In the field of building doors and windows, lift windows are widely used. Traditional lift windows mostly rely on pulleys and steel cables, or gears and chains as driving components. For example, the "Electric Lift Window" (publication number CN118911556A) applied for by Fujian Guohua Technology Holding Co., Ltd., uses a storage groove in the top wall inside the frame and sliding cavities on both sides to raise and lower the window core using a reel and a hanging rope. However, the hanging rope is prone to fatigue damage after long-term use, which reduces its service life and affects the overall lifespan of the lift window; while the chain has the risk of skipping teeth when carrying heavy objects, which may cause impact to the window sash and endanger safety. At the same time, existing transmission mechanisms such as motors often occupy space in the upper frame and side frame, making it difficult to install supporting systems such as electric screens. Based on these problems, this utility model proposes a top rod driven lift window structure, hoping to solve the above-mentioned drawbacks through innovative design. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a top rod driven lifting window structure, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a top-rod driven lifting window structure, comprising a window frame, a lifting window, a drive transmission system, a guide system, and a controller. The drive transmission system is electrically connected to the controller. By operating the controller, the lifting window, driven by the drive transmission system and guided by the guide system, is lifted and lowered within the window frame. The drive transmission system is a top rod located within the window frame on the side of the lifting window, with both ends connected between the window frame and the lifting window. The guide system includes a track and pulleys sliding within the track. The track is installed on the side frame of the window frame, and the pulleys are installed on the side frame of the lifting window. The track includes a straight section at the lower end and a variable track section at the upper end. Driven by the top rod, the lifting window changes track and opens and closes on the window frame.

[0008] Preferably, the top body and output end of the top rod are hinged to the window frame and the lifting window, respectively.

[0013] (III) Beneficial Effects

[0014] This utility model provides a top rod driven lifting window structure. It has the following beneficial effects:

[0015] 1. This top-rod driven lifting window structure differs from traditional lifting windows that often use wire ropes, chains, or motors driving screws. Wire ropes are prone to fatigue damage, chains pose a risk of tooth skipping, and screw drives may suffer from low efficiency or require excessively high installation precision. This invention uses a top-rod motor as the drive source, directly pushing the lifting window through the extension and retraction of the top rod, avoiding the drawbacks of wire ropes and chains, and offering advantages such as simple structure and direct power transmission.

[0016] 2. Compared to existing technologies where the motor and other transmission mechanisms often occupy both the upper and side frames, limiting the installation of supporting systems, this top-rod driven lifting window structure uses a different design. The top-rod fixing base is installed on the lower side frame, and the top-rod motor is connected via a hinge, saving space on the upper frame and making it possible to install electric curtains and other supporting facilities later. This also results in a simpler and more aesthetically pleasing overall appearance. Attached Figure Description

Detailed Implementation

[0024] This utility model embodiment provides a lifting window structure driven by a top rod 30, such as... Figure 1-6As shown in the figure, this is a half-view of the lift window. In practice, in order to ensure the balance and smoothness of the lift window 20's lifting and opening, the components are mostly arranged symmetrically on both sides. Therefore, the technical solution of this case is described using the component arrangement on one side as an example, including the window frame 10, the lift window 20, the drive transmission system, the guide system, and the controller. The window frame 10 includes the upper frame, the side frame, and the horizontal stile; the lift window 20 includes the upper and lower frames and the side frame; the drive transmission system is electrically connected to the controller. By operating the controller, the lift window 20 is driven by the drive transmission system and guided by the guide system, and is lifted and connected within the window frame 10. The controller is existing technology and can be purchased and configured on the market according to actual needs, so it will not be described in detail here.

[0025] In this technical solution, the drive transmission system uses the top rod 30 as the power source, including the top rod 30 motor, the motor fixing base 50, the motor fixing shaft 51, the connecting shaft 61, and the sash bearing block 60. The top rod 30 is located inside the window frame 10 on the side of the lifting window 20, and its two ends are connected between the window frame 10 and the lifting window 20. The guide system includes a track and pulleys 40 that slide within the track. The track is installed on the side frame of the window frame 10, and the pulleys 40 are installed on the side frame of the lifting window 20. The track includes a straight area at the lower end and a variable track area at the upper end. Under the drive of the top rod 30, the lifting window changes track and opens and closes on the window frame 10.

[0026] In embodiment one, the top body 31 and output end 32 of the top rod 30 are hinged to the window frame 10 and the lift window, respectively. For example... Figures 1 to 5 As shown, the top body 31 and output end 32 of the top rod 30 are respectively hinged to the window frame 10 and the lift window. The top body 31 of the top rod 30 is hinged to the window frame 10 through the motor fixing base 50. Specifically, the top body 31 is hinged to the motor fixing base 50 through the motor fixing shaft 51. The motor fixing base 50 is installed on the window frame 10. The output end 32 of the top rod 30 is hinged to the side frame of the lift window 20 through the sash bearing block 60. Specifically, the output end 32 is hinged to the sash bearing block 60 through the connecting shaft 61. The sash bearing block 60 is installed on the lift window 20.

[0027] In embodiment two, the top body 31 of the top rod 30 is fixedly connected, and its output end 32 is connected to the lifting window via a movable component. For example... Figure 6As shown, the top body 31 of the top rod 30 is fixedly connected (the top body 31 is fixedly connected to the window frame 10, and the bottom end of the top body 31 is connected to the motor fixing base 50 without changing it. It is only necessary to fix the top body 31 to the window frame 10. In this embodiment, the top body 31 is fixed by the fixing hoop 90). Its output end 32 is movably connected to the lifting window. In this embodiment, the moving part is a linkage group. The output end 32 of the top rod 30 is hinged to one end of the linkage group. The other end of the linkage group is hinged to the lifting window 20 through the sash bearing block 60. The linkage group includes a first linkage 91 and a second linkage 92, which are hinged to each other.

[0028] The movable parts include, but are not limited to, the linkage group in Embodiment 2, as well as other embodiments, such as chains, tension, etc. The output end 32 of the top rod 30 is connected to the side frame of the lifting window through the chain. Specifically, the output end 32 of the top rod 30 is hinged to one end of the chain, and the other end of the chain is hinged to the sash support block 60. The sash support block 60 is fixed to the side frame of the lifting window.

[0029] Both Embodiment 1 and Embodiment 2 include the reversible arrangement of the top rod 30, such as setting the top body 31 of the top rod 30 to the lifting window 20, and setting the output end 32 of the top rod 30 to the window frame 10, that is, these arrangements are all included.

[0030] Furthermore, in order to ensure the smooth lifting and lowering of the window 20, the track includes an upper track 71 and a lower track 72, which are respectively set on the side frame of the window frame 10. The upper track 71 and the lower track 72 are slidably connected to the corresponding upper track 71 and lower track 72, and the pulleys 40 are installed on the side frame of the window.

[0031] Specifically, the pulley 40 is installed on the side frame of the lift window 20 via the pulley fixing block 80, and the pulley 40 is mounted on the pulley fixing block 80.

[0032] In the technical solution, the push rod 30 is a general term for telescopic power components, such as hydraulic rods, pneumatic rods, electric rods, etc. Preferably, the push rod 30 is an electric push rod, and the model of the electric push rod is TOMUU.

[0033] Working principle: When the window opens and closes, the motor of the top rod 30 operates, and the extension and retraction of the top rod 30 causes the lifting window 20 to rise and fall within the window frame 10. At the same time, the pulley 40 and the track can control the running trajectory of the lifting window 20. Specifically, the controller is operated, and the controller causes the extended end of the top rod 30 to extend and retract. When the extended end extends, it pushes the lifting window 20 to move upward along the track. In the straight area, the lifting window 20 moves vertically upward. In the track changing area, the lifting window 20 moves upward and to one side under the drive of the top rod 30, realizing the track changing and closing of the lifting window. Conversely, when the extended end of the top rod 30 retracts, the movement is reversed.

[0034] In summary, the lifting window structure driven by the top rod 30 differs from traditional lifting windows that often use wire ropes, chains, or motors driving screws. Wire ropes are prone to fatigue damage, chains pose a risk of tooth skipping, and screw drives may suffer from low efficiency or require excessively high installation precision. This invention uses a motor in the top rod 30 as the drive source, directly pushing the lifting window 20 through the extension and retraction of the top rod 30. This avoids the drawbacks of wire ropes and chains, offering advantages such as simple structure and direct power transmission.

[0035] The lifting window structure driven by the top rod 30 differs from existing technologies where the motor and other transmission mechanisms often occupy both the upper and side frames, limiting the installation of supporting systems. This solution mounts the top rod 30's fixed base on the lower side frame, and the top rod 30 motor is connected via a hinge, saving space on the upper frame and making it possible to install supporting facilities such as electric curtains later, while also resulting in a simpler and more aesthetically pleasing overall appearance.

[0036] The guiding system of this invention consists of a track and pulleys 40. The pulleys 40 slide within the track, precisely controlling the trajectory of the lifting window 20 and ensuring a smooth and stable lifting process. Compared to some traditional simple guiding structures, this guiding method offers higher stability and reliability.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
