Description

An intelligent door lock is an actuating component for locking the door in an access control system.

[0003] The lock body of an intelligent lock is an important component of an intelligent door lock. The existing lock body of an intelligent lock is transformed from the lock body of a traditional mechanical door lock. The lock body of an intelligent lock often realizes the extension of the oblique tongue and the outer lock tongue through a stepped transmission method. That is, a first limiting groove and a second limiting groove are provided in the lock body of the mechanical door lock. When the rotation of the lock core corresponds to the first limiting groove, the oblique tongue extends out of the lock body. When the rotation of the lock core corresponds to the second limiting groove, the oblique tongue and the outer lock tongue extend out of the lock body at the same time. The lock core of the existing intelligent lock is driven by a motor to rotate.

[0044] Among them, the second limiting member 527 includes a second limiting groove 527-1 and a second limiting rod 527-2. The second limiting groove 527-1 is arranged on the second intermediate member 524 along the first direction X. The second limiting groove 527-1 includes a third limiting surface 527-11 and a fourth limiting surface 527-12 arranged along the first direction X. That is, both ends of the second limiting groove 527-1 along the first direction X have the third limiting surface 527-11 and the fourth limiting surface 527-12. The second limiting groove 527-1 further includes a second idle stroke position 527-13 located between the third limiting surface 527-11 and the fourth limiting surface 527-12. That is, when the second limiting rod 527-2 does not contact the third limiting surface 527-11 or the fourth limiting surface 527-12, it is in the second idle stroke position 527-13. The second limiting rod 527-2 is connected to the first intermediate structure 523-1. The second limiting rod 527-2 extends into the second limiting groove 527-1 along the third direction Z. Therefore, the second limiting rod 527-2 can rotate synchronously with the first intermediate structure 523-1. And under the rotation of the first intermediate structure 523-1, when the second limiting rod 527-2 abuts against the third limiting surface 527-11 and the fourth limiting surface 527-12, the first intermediate structure 523-1 and the second intermediate member 524 rotate synchronously, so as to realize the synchronous movement of the oblique tongue member 310 and the outer locking tongue member 320. Further, when the second limiting rod 527-2 is located within the second idle stroke position 527-13, the first intermediate structure 523-1 rotates alone, and at this time, the oblique tongue member 310 moves alone. The difference between the second limiting rod 527-2 of the present application contacting the third limiting surface 527-11 or contacting the fourth limiting surface 527-12 lies in the different directions of driving the second intermediate member 524 to move.

[0045] Attached Figure 6 is a schematic structural diagram of the first limiting member 526 of the present application. Please refer to Attached Figure 6As shown in the figure, the intermediate transmission member 520 of the present application further includes a first limiting member 526. The first limiting member 526 includes a first limiting groove 526-1 and a first limiting rod 526-2. The first limiting groove 526-1 is provided on the first driving gear 522, and the first limiting groove 526-1 is arranged along the rotation trajectory of the first driving gear 522, that is, the first limiting groove 526-1 is an arc groove. The first limiting groove 526-1 includes a first limiting surface 526-11 and a second limiting surface 526-12 arranged at both ends of the rotation trajectory of the first driving gear 522. The first limiting groove 526-1 further includes a first idle position 526-13 located between the first limiting surface 526-11 and the second limiting surface 526-12. That is, when the first limiting rod 526-2 is not in contact with the first limiting surface 526-11 or the second limiting surface 526-12, it is in the first idle position 526-13. The first limiting rod 526-2 is connected to the first intermediate structure 523-1, and the first limiting rod 526-2 extends along the third direction Z into the first limiting groove 526-1. Therefore, the first intermediate structure 523-1 can move synchronously with the first limiting rod 526-2. And when the first driving gear 522 rotates, when the first limiting rod 526-2 abuts against the first limiting surface 526-11 and the second limiting surface 526-12, the first driving gear 522 and the first intermediate structure 523-1 rotate synchronously. At this time, the inclined tongue member 310 is driven to move synchronously by the first driving gear 522 and the first intermediate structure 523-1. When the limiting rod is located within the first idle position 526-13, the first driving gear 522 rotates alone. At this time, the inclined tongue member 310 is driven to move alone by the first driving gear 522. The difference between the first limiting rod 526-2 of the present application contacting the first limiting surface 526-11 or contacting the second limiting surface 526-12 lies in the different directions of driving the first intermediate structure 523-1 to move.

[0046] Further, during this movement process, the first limiting groove 526-1 located on the first driving gear 522 is the driving member, while the first limiting rod 526-2 located on the first intermediate structure 523-1 is the driven member.
