Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and in particular to a lock tongue driving structure of an intelligent door lock. Background Art

[0002] Smart door locks refer to locks that are more intelligent and simple in terms of user security, identification, and manageability. They are usually equipped with electronic unlocking systems, such as fingerprint, facial recognition, magnetic card sensing, etc. In order to prevent the lock from being able to be opened and closed normally when the electronic unlocking system is powered off or fails, smart door locks are generally also equipped with a mechanical unlocking structure.

[0003] The mechanical unlocking structure of existing smart door locks usually adopts a method in which the rotation of the lock cylinder directly drives the lock tongue to retract. Due to the lack of a linkage structure, this method requires the key to drive the lock cylinder to rotate a large angle when unlocking or locking the door before the lock tongue can be fully extended or retracted into the lock body, causing inconvenience in operation and affecting the user experience.

[0015] Furthermore, the thickness of the second rod body is greater than the sum of the thicknesses of the second extension arm and the connecting plate.

[0016] In the above technical solution, the thickness of the second rod body is greater than the sum of the thicknesses of the second extension arm and the connecting plate, so that the second rod body can be opposite to the second extension arm and the connecting plate at the same time, so that the second extension arm can rotate and push the second rod body, and the second rod body can push the connecting plate under the drive of the first paddle.

[0017] Furthermore, the lock core includes a rotatable paddle, the first paddle and the second paddle are respectively provided with a first boss and a second boss, the first boss and the second boss are respectively located on two sides of the paddle and are opposite to the paddle in space.

[0018] In the above technical solution, the paddle plate can push the first paddle and the second paddle respectively through the first boss and the second boss, and the first boss and the second boss are respectively arranged at the two ends of the paddle plate, so that when the paddle plate rotates in two directions, it pushes the first paddle and the second paddle respectively, thereby realizing locking and unlocking the door.

[0019] Furthermore, the first paddle and the second paddle are respectively provided with a first avoidance groove and a second avoidance groove, and the lock core is penetrated through the first avoidance groove and the second avoidance groove.

[0020] In the above technical solution, by setting the first avoidance groove and the second avoidance groove, the first paddle and the second paddle can be arranged around the outer periphery of the lock core. On the one hand, it is ensured that the rotation of the paddle plate can effectively drive the first paddle and the second paddle.
