Description

Technical Field

[0001] This utility model relates to the field of hinges, and in particular to an electrically powered hinge. Background Technology

[0002] In hotels, guesthouses, or some rental properties, it's necessary to install low-voltage wiring outside the door to connect to the inside for purposes such as electronic unlocking. However, to avoid damaging the wall by drilling additional holes in the door or wall, the wiring is typically routed through hinges. This allows for connection between the inside and outside of the door without additional drilling. However, since the first and second hinge bodies, which connect to the door and door frame respectively, need to rotate relative to each other, the safety of the hinges is crucial.
