Description

Technical Field

[0001] This utility model relates to the field of lifting window technology, specifically a lifting window that is easy to open and close. Background Technology

[0002] In modern architecture, windows are a crucial structural element connecting the interior and exterior. They not only provide essential lighting and ventilation but also significantly impact indoor comfort and safety. Intelligent electric lift windows, as a new type of window, rely on electric components for opening and closing and can be controlled by an intelligent system. They offer unique advantages such as ease of operation, intelligent operation, and rich functionality, and are widely used in buildings, homes, factories, and other fields.

[0003] For the lifting switch drive of the window, in order to improve the working load-bearing stability of the window movement drive, the existing lifting windows mostly adopt a dual-motor drive structure. The dual-motor drive relies on synchronous electrical signals for working control. Although it has a certain synchronous reliability, in the event of program abnormality or abnormal power supply, the asynchronous operation of the two sides can easily cause the window to deflect and get stuck, resulting in poor working stability. Therefore, a lifting window that is easy to open and close is proposed. Utility Model Content

In order to drive the installation with the transmission screw 5, threaded sleeve seats 8 are fixedly installed on both sides of the lifting window body 3. The end post of the transmission screw 5 is threadedly connected to the threaded hole in the middle of the threaded sleeve seat 8. The lifting window body 3 is driven by the two sets of drive motors 4 in conjunction with the transmission screw 5. The movement and working load-bearing stability of the lifting window body 3 can be effectively improved by the dual motors and screw transmission. In order to improve the rotational support stability of the transmission screw 5, the lower end of the transmission screw 5 is connected to the shaft seat rotational support provided on the side of the mounting window frame 1.

[0028] Synchronous shafts 6 are provided on the mechanical transmission sides of the two sets of drive motors 4, as detailed in the attached document. Figure 2 As shown, in order to achieve mechanical transmission synchronization, a synchronous coupling is provided on the side of the reducer. The two ends of the synchronous shaft column 6 are fixedly installed to the ends of the two sets of synchronous couplings through bushings. A synchronous shaft column 6 is provided between the two sets of drive motors 4. The two ends of the synchronous shaft column 6 are respectively connected to the shaft column ends of the reduction transmission structure of the two sets of drive motors 4. Through the synchronous connection of the synchronous shaft column 6, the mechanical synchronization of the two sets of drive motors 4 can be achieved.

In order to improve the stability of the middle support of the synchronous shaft column 6, a shaft column support 7 is fixedly installed on the top side of the window frame 1 by bolts. The middle rotation support of the synchronous shaft column 6 is installed on the inner side of the shaft hole in the middle of the shaft column support 7.

[0029] To achieve anti-pinch protection for the lifting window 3, as shown in the attached document... Figure 1 As shown, infrared sensors 13 are installed on both sides of the middle part of the installation window frame 1. The infrared sensors 13 are infrared photoelectric sensors in the prior art.

[0030] The sealing end seat 9 is installed on the upper part of the lifting window body 3 and is used for sealing the joint on the upper closed side of the lifting window body 3, as shown in the attached figure. Figure 5 As shown, the sealing end seat 9 is a strip-shaped rubber strip seat. To facilitate the connection and installation of the sealing end seat 9, an installation groove 10 is provided in the middle of the bottom side of the sealing end seat 9. The sealing end seat 9 is fitted and fixed to the upper part of the lifting window body 3 by the mounting groove 10 and the structure adhesive. In order to achieve edge sealing, an outer sealing edge piece 11 and an inner sealing edge piece 12 are respectively provided on the front and rear sides of the sealing end seat 9. The upper part of the outer sealing edge piece 11 is arc-shaped and is fixedly installed on the front side of the sealing end seat 9. The lower part of the inner sealing edge piece 12 is flat and is fixedly installed on the rear side of the sealing end seat 9. Through the sealing of the outer sealing edge piece 11 and the inner sealing edge piece 12, the contact sealing of the lifting window body 3 in the open and closed state can be guaranteed, which is conducive to improving the sealing and protection of the window body.

[0031] Working principle or structural principle: When the window is opened and closed, the operation of the window is controlled by the remote control or the operation panel 14. When the window is open, the two sets of drive motors 4 are controlled by synchronous electrical signals to work synchronously. The drive motors 4 drive the transmission screws 5 to drive the two sides of the lifting window 3 to move synchronously and open the window. At the same time, during the operation, the shaft column of the reducer of the two sets of drive motors 4 is synchronously connected through the synchronous shaft column 6. The synchronous connection of the synchronous shaft column 6 can realize the mechanical synchronization of the two sets of drive motors 4. Combined with the synchronous control of electrical signals, a double synchronous protection structure is formed to avoid the lifting window 3 from jamming due to the asynchronous driving of the two sides. After the lifting window 3 moves down and opens, the lower flat part of the inner sealing edge piece 12 at the rear of the sealing end seat 9 is in contact with the beam surface of the upper part of the fixed window 2 to achieve the sealing of the closed side of the window and ensure the contact sealing of the lifting window 3 when it is open.

[0032] When the window is closed, the synchronous displacement of both sides of the lifting window 3 is achieved through the synchronous drive of the synchronous shaft column 6 via the electrical signal drive, thereby driving the window to move upward and close. After the lifting window 3 moves upward and closes, the upper arc surface of the outer sealing edge piece 11 at the front of the sealing end seat 9 comes into contact with the inner surface of the retaining groove at the upper part of the mounting window frame 1, thereby achieving a close and sealed fit on the closed side of the window and ensuring the contact sealing performance of the lifting window 3 when it is closed.

[0033] In summary, this lifting window adopts a dual-motor working drive structure. Two sets of drive motors 4, in conjunction with transmission screws 5, drive the lifting window body 3. The dual motors and screw transmission effectively improve the movement and working load stability of the lifting window body 3. A synchronous shaft 6 is set between the two sets of drive motors 4. The two ends of the synchronous shaft 6 are connected to the shaft ends of the reduction transmission structure of the two sets of drive motors 4, respectively. The synchronous connection of the synchronous shaft 6 can realize the mechanical synchronization of the two sets of drive motors 4. Combined with the synchronous control of electrical signals, a double synchronous protection structure is formed, which can effectively improve the lifting drive stability of the window body. Furthermore, a sealing end seat 9 is set on the upper part of the lifting window body 3. The upper two sides of the sealing end seat 9 are respectively provided with an outer sealing edge 11 and an inner sealing edge 12. The contact sealing of the outer sealing edge 11 and the inner sealing edge 12 can ensure the contact sealing of the lifting window body 3 in the open and closed state, which is conducive to improving the sealing and protection of the window body.
