Description

Technical Field

[0001] This utility model relates to the field of lifting window technology, specifically a lifting window employing a concealed self-draining system. Background Technology

[0002] Windows are an essential component of buildings, serving many crucial functions such as lighting, ventilation, insulation, soundproofing, and security. Properly opening and closing windows helps with indoor air circulation, improves indoor air quality, enhances the living environment, and benefits human health. As people's living standards continue to improve, window opening mechanisms are increasingly focused on intelligence and convenience. Electric lift windows, as a new type of window, utilize motors as a drive structure to automatically open and close, meeting people's demands for a convenient, comfortable, and safe living environment.

[0003] Electric lift windows use a motor to drive the movable window body up and down. Existing lift windows mostly use a cable-driven drive structure for the lifting transmission of the window body. Although the cost is low, its load capacity and working stability are not good. In order to facilitate the drainage of external rainwater, a drainage structure needs to be set at the bottom of the window body. In order to prevent external insects and foreign objects from entering the drainage structure, a protective cover with filter holes needs to be set on the opening side of the drainage channel. Traditionally, the protective cover is connected to the channel through a fitting method. When cleaning the drainage channel, it is very laborious to remove the protective cover and it is easy to cause the protective cover to fall off, which is very inconvenient to use. Therefore, a lift window with a hidden self-drainage system is proposed. Utility Model Content

Figure 1 As shown, the fixed window panel 2 and the movable window panel 3 are installed in a staggered manner. The fixed window panel 2 is a fixed window structure and is fixedly installed on the upper part of the inner frame of the mounting frame 1.

[0027] The movable window panel 3 is vertically mounted to the inside of the mounting frame 1 via a drive mechanism. Specifically, the drive mechanism is used to drive the movable window panel 3 to rise and fall. The drive mechanism includes a drive motor 4, drive pulleys 5, and a transmission toothed belt 6. The drive pulleys 5 are arranged in pairs, as shown in the attached diagram. Figure 4 As shown, to facilitate the connection and installation of the movable window panel 3, a lifting mounting groove 7 is provided in the middle of the mounting frame 1. The lifting mounting groove 7 is located on the inner frame side of the mounting frame 1. The edge of the movable window panel 3 is slidably fitted into the mounting frame 1. A set of drive pulleys 5 is installed on the drive end of the drive motor 4 for driving the toothed belt 6. Specifically, see attached... Figure 2 As shown, the drive motor 4 is a geared motor. To improve transmission stability, a reducer is fixedly installed at the drive end of the drive motor 4. The reducer is fixedly installed on the top center of the mounting frame 1 by bolts. The shaft end of the drive motor 4 is fixedly connected to the drive input shaft end of the reducer. Output shafts are provided on both sides of the reducer. A transmission shaft column 8 is installed at the end of both sets of output shafts. The upper drive pulley 5 is fixedly installed at the end of the transmission shaft column 8. To improve the transmission support stability of the transmission shaft column 8, shaft column supports 9 are fixedly installed on both sides of the top of the mounting frame 1. The end of the transmission shaft column 8 is rotatably supported by the shaft hole at the top of the shaft column support 9.

[0028] Another set of drive pulleys 5 is mounted on the side of the mounting frame 1 via a rotating shaft support. Specifically, see attached... Figure 5 As shown, the lower drive pulley 5 is rotatably supported by the mounting shaft column set on the side of the mounting frame 1. The transmission toothed belt 6 is installed on the upper part of the two sets of drive pulleys 5. In order to realize the drive connection, drive connecting blocks 10 are fixedly installed on both sides of the movable window panel 3. The drive connecting blocks 10 are fixedly connected to the drive connecting seat set in the middle of the transmission toothed belt 6 by bolts. The double-sided toothed belt transmission structure is adopted. The drive pulleys 5 and the transmission toothed belt 6 are used to drive the movable window panel 3. The transmission toothed belt 6 is installed and connected through two sets of fixed shaft installed drive pulleys 5. During operation, the transmission toothed belt 6 can be kept in a relatively taut working state, so that the fixed window panel 2 has a good drive load capacity at both the top and bottom, which greatly improves the working stability of the window.

[0029] To improve the safety and security of the form during operation, as shown in the attached document... Figure 1 As shown, an anti-pinch sensor 11 is provided on the lower side of the mounting frame 1. The anti-pinch sensor 11 is an infrared sensing sensor in the prior art. When the movable window panel 3 moves down to close, the anti-pinch sensor 11 performs real-time sensing and detection on the area below the middle of the mounting frame 1, which can avoid pinching accidents caused by the user's arm being accidentally placed. In order to facilitate the operation control of the window, an operation panel is provided on the inner side of the mounting frame 1. In order to improve the support stability of the middle of the mounting frame 1, a central crossbeam 15 is fixedly installed in the middle of the mounting frame 1. In order to improve the decorative aesthetics and functionality of the window, a lighting strip is provided at the lower part of the central crossbeam 15.

[0030] To facilitate water drainage, a drainage channel is provided on the lower opening side of the lifting mounting groove 7. This drainage channel is concealed within the lifting mounting groove 7, ensuring the structural aesthetics of the window. For further water drainage, a drainage channel 12 is provided on the outer side of the lifting mounting groove 7, extending through the outer side of the drainage channel. To facilitate installation protection on the drainage channel 12 side, a channel protective cover 13 and a cover connecting post 14 are provided on the opening side of the drainage channel 12, as shown in the attached diagram. Figure 3As shown, a filter slot is provided in the middle of the drainage channel protective cover 13. The drainage channel protective cover 13 can block and seal the opening side of the drainage channel 12, ensuring normal drainage of water while preventing the entry of external insects and foreign objects. The cover connecting post 14 is inserted into the drainage channel 12 from the top. The end of the cover connecting post 14 is inserted into the shaft hole at the end of the drainage channel protective cover 13. The drainage channel protective cover 13 is supported by the cover connecting post 14 and flipped to close the opening side of the drainage channel 12. It can be easily and quickly flipped open. The quick opening and closing operation provides better convenience of operation compared to the traditional interlocking cover structure, and can effectively improve the cleaning and maintenance convenience of the window drainage structure. In order to lock and limit the closed channel protective cover 13, a limit block is provided at the end of the channel protective cover 13. After closing, the limit block engages with the groove structure on the inner side of the drainage channel 12, which can realize the closing limit of the channel protective cover 13. In order to facilitate the flipping and opening of the channel protective cover 13, a latching groove block is provided on the outer side of the end of the channel protective cover 13.

[0031] Working principle or structural principle: During operation, when opening and closing the window, the window is controlled via the operation panel or remote control. When the window moves upward to open, the drive motor 4 drives the drive pulleys 5 on both sides to rotate synchronously. The rotating drive pulleys 5 drive the transmission toothed belt 6 on their upper part to move the movable window panel 3 upward within the lifting mounting groove 7. During the process, the transmission toothed belt 6 is kept taut by the two sets of drive pulleys 5, so that the fixed window panel 2 has good driving load capacity at both the top and bottom. During the suspension, the stability of the movable window panel 3 can be guaranteed. Similarly, when the movable window panel 3 moves downward to close, the drive pulleys 5 and the transmission toothed belt 6 drive the movable window panel 3 downward. At the same time, the anti-pinch sensor 11 detects the lower part of the window in real time. When an obstacle blocks the detection area, the drive motor 4 stops working, so that the moving movable window panel 3 is in a suspended state. After the obstacle is removed, the movable window panel 3 continues to close by triggering the closing signal again.

[0032] In summary, this lifting window adopts a double-sided toothed belt transmission structure. The drive pulley 5 and the transmission toothed belt 6 drive the movable window panel 3. The transmission toothed belt 6 is connected to the drive pulley 5 installed on two fixed shafts. During operation, the transmission toothed belt 6 can be kept in a relatively taut working state, so that the fixed window panel 2 has good driving load capacity at both the top and bottom, which greatly improves the working stability of the window. In addition, a hidden drainage structure is adopted, which hides the drainage structure in the lower inner side of the lifting installation groove 7. A groove protective cover 13 is provided on the external drainage groove 12 side. One side of the groove protective cover 13 is supported by the cover connecting column 14 and is flipped up. The flipping allows for convenient and quick opening and closing. Compared with the traditional interlocking cover structure, it has better opening and closing operation convenience and can effectively improve the cleaning and maintenance convenience of the window drainage structure.
