Electric lifting door and window

Abstract

The invention relates to the technical field of doors and windows, and particularly relates to an electric lifting door and window. The electric lifting door and window comprises a window frame / door frame and a movable window sash capable of sliding up and down along the window frame / door frame. A driving device is provided with a transmission shaft driven by a lifting motor. The transmission shaft is horizontally arranged, and the two ends of the transmission shaft extend out of the two opposite side faces of the movable window sash correspondingly and are each fixedly provided with a gear. Racks are fixedly arranged on the left inner side wall and the right inner side wall of the window frame / door frame correspondingly. The gears are engaged with the racks. Along with rotation of the lifting motor, under the interaction of the gears and the racks, the movable window sash is driven to slide up and down along a sliding rail on the inner side face of the window frame / door frame, and accordingly the movable window sash is opened or closed. According to the electric lifting door and window, the transmission shaft is driven by the lifting motor to extend out in two directions, the movable window sash is driven to slide up and down in cooperation with the gears and the racks, movement is stable, friction force is small, simpleness and high efficiency are achieved, movement is flexible, the clamping stagnation delay phenomenon is avoided, the occupied space is small, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to an electric lifting door and window. Background technique [0002] The lifting doors and windows adopt the opening method of lifting up and down, and can hover at any position. It has the advantages of ventilation effect, good air tightness, no space occupation, and convenient cleaning. Especially two-way lift doors and windows. [0003] Controlling the switch of the lifting door and window in an electric way can further improve the portability of the lifting door and window. For this reason, Chinese utility model patent CN 208564326 U discloses a semi-automatic aluminum alloy lifting window, including a window part and a folding part , the folding part includes a driving part and an execution part, the driving part includes a lifting motor, and the lifting motor is connected to a first rotating shaft; the side of the first rotating shaft is fixed with a first gear, an...

AI Technical Summary

Problems solved by technology

However, this solution has the following problems: the first rotating shaft and the second rotating shaft are respectively suspended and driven by wire ropes to drive the two sides of the sliding window, and the first rotating shaft and the second rotating shaft are meshed by the first gear and the second gear. There is a transmission error, so the first shaft and the second shaft cannot be completely synchronized and rotate at the same speed, so the lifting of the sliding window is not smooth, and the sliding window is driven by the wire rope suspension, due to the soft nature of the wire rope itself , it will also make the lifting of the sliding window unstable. In addition, this setting method will cause the drive part to take up a lot of space, which is not practical enough
