Description

Unlocking transmission structure of full-automatic electronic door lock

Technical Field

The utility model relates to a full-automatic electronic door lock, especially a full-automatic electronic door lock transmission structure that unblanks.

Background

The current electronic door locks can be broadly divided into semi-automatic and fully automatic, the semi-automatic being: after the identity is identified, the motor drives the clutch piece to move, so that the door opening shifting fork is driven by the door outer handle, and then the lock tongue is driven to retract by rotating the door outer handle, so that unlocking is realized; the full-automatic process comprises the following steps: after the identity is identified, the motor directly drives the lock bolt to retract, and at the moment, a user can directly push or pull the door body (the relative semi-automatic advancement is that the action of rotating the handle to unlock is not available).

Chinese patent publication No. CN109555374A discloses a full-automatic lock body and a method for opening and closing the door thereof in 2019, 4.2.A lock case includes a lock plate, a lock plate mounted on a door frame, and a motor assembly having a gear at an end thereof, the lock case includes an upper cover, a lower cover, and lock plates, the upper cover, the lower cover, and the lock plates are connected with each other in pairs to form a closed cavity, and the lower cover is provided with a scissor tongue mechanism, a swing curved lever, a guide gear assembly, and a lock tongue assembly; the scissors tongue mechanism comprises an induction oblique tongue assembly, a scissors tongue assembly and a scissors tongue positioning assembly, the top of the induction oblique tongue assembly is rotatably connected with the end part of the scissors tongue positioning assembly through a guide mechanism, one end surface of the scissors tongue positioning assembly is in contact with the end surface of the scissors tongue assembly, the bottom of the scissors tongue positioning assembly is matched with the top of a swinging curved rod, the bottom of the swinging curved rod is in contact with a guide gear assembly, one end of the guide gear assembly is in contact with the lock tongue assembly, and the other end of the guide gear assembly is meshed with a motor assembly through a gear. The full-automatic lock body of the structure is not provided with a mechanical lock cylinder opened by a key, when the electric quantity is exhausted, an operation panel on the door body needs to be opened, the gear set is screwed by the cross screwdriver to unlock the scissor bolt assembly and retract the scissor bolt assembly, and then the mechanical unlocking is completed. However, since the gear set is always in a linkage state with the pinion on the motor through the guide gear, and the force of the guide gear is transmitted to the pinion, which is an acceleration transmission, it needs a larger force to drive the pinion to rotate (the pinion drives the large gear when the motor is unlocked, which is relatively labor-saving), and the teeth of the gear are easily damaged.
