Description

Technical Field

[0001] This utility model relates to the technical field of sliding windows, specifically to an electric sliding window. Background Technology

[0002] Sliding windows, as an important indoor design element for ventilation and lighting, are widely used in various buildings. When ventilation is needed, a person must push the window open; when closing, the window sash is pulled back. However, traditional sliding windows require manual opening and closing actions, and it's difficult to guarantee that the window will open or close completely, affecting the user experience. To address these issues, publication number CN202320327756.1 discloses an electric sliding window for vehicles, including a window frame, a window body, an opening and closing drive mechanism, and an electronic lock. The window frame is mounted on the vehicle, with a window opening extending through it. One end of the window body is hinged to the window frame, and the window body and window opening are positioned opposite each other. The opening and closing drive mechanism is used to drive the window body to open or close relative to the window. The electronic lock's hook is located on the window body, and the electronic lock's latch is located on the window frame, or the electronic lock's hook is located on the window frame, and the electronic lock's latch is located on the window body. The electronic lock and the opening and closing drive mechanism are linked. When the opening and closing drive mechanism drives the window body to close relative to the window, the electronic lock's hook engages with the latch to lock. When the opening and closing drive mechanism drives the window body to open relative to the window, the electronic lock's hook disengages from the latch to unlock. This achieves automatic window closing and opening, as well as automatic locking and unlocking, making it convenient, safe, and reliable to operate.

[0003] However, the electric sliding window still has the following problems: 1. The opening angle of the electric sliding window body is limited, and it cannot open to a large angle, which affects the ventilation effect and prolongs the opening and closing time, making it difficult to meet the needs of rapid ventilation or emergency opening and closing; 2. The existing electric sliding window has no limit support function. The window body is supported and fixed by the motor after opening, which has poor support stability and affects the service life of the motor. Utility Model Content

One of the sleeves is provided with a connecting shaft, and the other sleeve is connected to the connecting shaft to form a rotatable connection. The hinge mechanism 6 is used for the flip connection between the window sash 3 and the window frame 2.

[0047] See appendix Figure 9 The motor 7 is equipped with a motor fixing plate, and the motor 7 is fixed to the inner wall of the stepped protrusion through the motor fixing plate. The motor 7 includes a housing 71, a motor 72, a planetary reducer 73, and a bearing 74. The motor 72 is connected to the planetary reducer 73 and is disposed inside the housing 71. The end of the planetary reducer 73 is provided with a fixing ring, and the fixing ring is connected to a fixing seat. The fixing seat is fixedly connected to the fixing plate 80 by a threaded screw structure. The fixing ring is also provided with a bearing. The rotating shaft 70 is connected to the motor 72.

[0048] The stepped protrusion has an insertion port, and the controller 5 is installed inside the stepped protrusion through the insertion port. The controller 5 has a handle motor 50, and the handle motor 50 has a handle switch. The panel 30 has a button 300 and a handle hole 301. The button 300 is located on the bottom or top surface of the panel 30 and is electrically connected to the controller 5. The handle hole 301 and the handle switch are on the same axis. The handle motor 50 also has a handle lock, which is located at the bottom of the stepped protrusion. The frame 20 has a groove for locking the handle lock. The controller 5 is used for control and signal processing. The handle hole 301 is used for... The controller 5 has an insertion hole for manual control of the unlocking or locking of the handle motor 50. In automatic mode, when the window sash 3 is opened, the control circuit receives a positive DC 24V power supply and powers the handle motor 50. The handle motor 50 pushes the locking point open and sends a feedback signal to the control circuit. The control circuit then starts the drive motor 7, rotating the motor arm 81 to drive the driven arm 82, thus opening the window sash 3. After the window sash 3 is fully opened, the motor arm 81 touches the limit shaft 821c, triggering a stall protection. The control circuit then cuts off the power supply and short-circuits the positive and negative terminals of the motor 72, amplifying the resistance through the planetary reducer 73 to prevent the window sash 3 from falling. When the window sash 3 is closed, the control circuit receives reverse DC24V power and supplies power to the handle motor 50 to confirm that the locking point is in the open state (to avoid collision). Upon receiving feedback, the drive motor 7 rotates in the reverse direction, causing the window sash 3 to close. After the window sash 3 is closed, the hook 810a of the motor arm 81 touches and engages with the limit shaft 821c, triggering the stall protection. The control circuit is then de-energized, and the control circuit closes the locking point through the handle motor 50, completing the sealing of the window sash 3. The handle assembly is used to unlock or lock the handle motor 50, thereby facilitating subsequent manual opening or closing operations of the window sash 3.

[0049] In manual mode, when manually opening the window, press button 300 to cut off the power supply to the control circuit to reduce resistance. Insert the handle through handle hole 301 to the handle switch on the handle motor 50 and rotate to unlock the locking point. After pulling out the handle, manually push the window sash 3 open. Once the window sash 3 is in place, press button 300 again to restore the motor 72 to the short-circuit state and fix the window sash 3. The manual window opening step is complete. When manually closing the window, press button 300 to cut off the power supply and manually push the window sash 3 to close it completely. Then insert the handle to the handle switch on the handle motor 50 and rotate to lock the locking point. Press metal button 300 again to restore the control circuit function.

[0050] The handle switch is located on the surface or bottom of the panel 30; the panel 30, the stepped protrusion, and the window frame 2 are all provided with sealing strips, and the first baffle 21 is provided with a fixing groove for installing and fixing the sealing strip. The sealing strip 9 serves as a buffer and seal when the window frame 2 and the window sash 3 are closed.

[0051] This invention utilizes a drive mechanism comprised of a hinge assembly and a motor to manually or automatically open and close the window sash. A driven arm, a fixed plate, and a motor arm, each with a first connecting part, a second connecting part, and a curved part, enable small-angle opening and closing of the window frame and sash, shortening operation time and meeting the needs for rapid ventilation or emergency opening and closing. It also allows for a maximum opening angle of 90° between the window sash and frame, accommodating subsequent full-open ventilation. A hook and a limiting shaft are provided for the window sash to engage with the limiting shaft when opened, providing limiting support. Combined with a motor equipped with a planetary reducer, which provides resistance support, multiple supports are formed, improving the stability of the window sash after opening and ensuring the motor's lifespan.
