Description

Technical Field

[0001] The utility model relates to the technical field of electric doors and windows, in particular to a universal electric window opener handle device and a door and window opener. Background Art

[0002] In today's building door and window industry, electric window openers, as a convenient and efficient window control device, are playing an increasingly important role. However, existing electric window openers have certain limitations in application, and most products are only compatible with specific types of door and window slots. With the diversification of architectural design and the increasing demand for window functions, this single-adaptability electric window opener can no longer meet the actual needs of the market. On the one hand, different types of door and window slots are widely present in buildings, and users are often restricted in their choice of electric window openers. They may need to equip doors and windows with different slot types with dedicated window openers, which increases costs and installation complexity. On the other hand, in some renovation projects of existing buildings, due to the uncertainty of the original door and window slot types, existing electric window openers are difficult to apply directly, which brings difficulties to the automation of window renovations.

[0003] Regarding door and window hardware notches, C-slot and U-slot are the most popular on the market, but the window openers for these two notch shapes are not universally compatible. A window opener consists of two parts: a window gear box and a handle gear box, which are used to drive the opening and closing of the door and window and unlock and lock the door and window, respectively. During installation, the handle gear box is installed in the C-slot or U-slot of the door and window, and the handle gear box can be used to electrically lock the door and window when closed.

[0004] Chinese invention patent publication number CN110005256A discloses an electric manual sash handle lock for electric casement sliding doors and windows. The lock mechanism utilizes an electric drive mechanism mounted on the upper or lower transmission lock bar. The electric drive mechanism comprises a housing, a rack, a clutch, and a motor. During electric unlocking and locking, the clutch is engaged, and the motor drives the lock bar, which in turn drives the lock tongue. To manually unlock, a brief click of the motor's rotary switch slightly rotates the motor, disengaging the clutch and enabling manual unlocking and locking. This invention is suitable for casement sliding windows.
