The operation principle (process) of the clutch structure of the smart lock of the present embodiment will be described in general with reference to fig. 6 to 8, wherein the reference numerals in the drawings define clockwise and counterclockwise directions:

(1) In the state of fig. 6, the knob 20 is rotated in the forward direction, so that the knob 20 drives the limit dial 40 to rotate clockwise; at this time, the pushing portion 41 of the limiting dial 40 pushes the dial block 51 of the clutch member 50 to rotate clockwise, and the square shaft 31 is adapted to the fixing groove of the clutch member 50, so that the square shaft 31 also rotates clockwise (normally, after the square shaft 31 rotates clockwise by about 90 degrees, the locking tongue matched with the square shaft 31 can be driven to extend outwards to complete locking; it should be noted that the control matching of the square shaft 31 to the locking tongue is the prior art, and is not described herein again); also, during the clockwise rotation of the position limiting dial 40, the dial wall 42 of the position limiting dial 40 dials the movable end 62 of the return spring, so that it also rotates clockwise to be limited to the second position limiting wall 12, i.e. the return spring also accumulates elastic force during this process (as shown in fig. 7);

(2) After the locking process of (1) is completed, the knob 20 is loosened, and at this time, because the return spring accumulates a certain elastic force, the movable end 62 of the return spring pushes (the toggle wall 42 of) the limit dial 40 to rotate counterclockwise until the movable end 62 of the return spring is limited by the first limit wall 11 (as shown in fig. 8);

(3) In the state (2), when unlocking is required, a key can be inserted into the lock cylinder 30 and screwed, so that the square shaft 31 (driving the clutch piece 50) rotates counterclockwise by 90 degrees, and the state of fig. 6 is returned.

(4) In the state of fig. 6, when the knob 20 is rotated in the reverse direction, the position-limiting dial 40 idles counterclockwise by a certain angle, and the position-limiting dial 40 is provided with a position-limiting portion 43 for limiting when the position-limiting portion 43 contacts the second position-limiting wall 12, so that the knob 20 cannot be rotated in the reverse direction any more.

Specifically, the included angle between the first limiting wall 11 and the second limiting wall 12 is slightly larger than 90 degrees. Preferably, a wear-resistant sleeve 70 is arranged between the knob 20 and the housing 10; the function of wear resistance and improvement of the smooth rotation of the knob 20 is achieved.

In practical application, a rotary disc 80 is arranged between the limit dial 40 and the knob 20, and the limit dial 40, the rotary disc 80 and the knob 20 are fixedly connected. The PCB 90 is arranged above the limit dial 40 of the shell 10, and the PCB 90 is in control connection with the square shaft 31; that is, in the above (3), in addition to the key for rotating the key cylinder 30, the square shaft 31 can be controlled to rotate counterclockwise by the PCB 90; the PCB 90 is provided with an interactive module, which may be a touch display screen, a fingerprint module, a key module, or the like; namely, the present application is applicable to intelligent (door) locks of various unlocking modes.

Further, it should be noted that: a third limiting wall 13 is arranged on one side of the second limiting wall 12 of the housing 10 away from the first limiting wall 11, and a fixed end 61 of the return spring is connected to the third limiting wall 13; the included angle between the third limiting wall 13 and the second limiting wall 12 is slightly larger than 90 degrees; the structure has the advantages that: the door can be simultaneously suitable for left-handed and right-handed opening, and only the fixed end 61 and the movable end 62 of the return spring need to be exchanged, and the others need to be correspondingly adjusted; thereby meeting the assembly requirements of different users.

The utility model is mainly designed to realize the rapid locking by designing a clutch structure of the intelligent lock, so that a user can rotate the knob; therefore, the safety of the intelligent lock is improved; secondly, the clutch structure design of this application is ingenious, can just can satisfy the demand of opening the door of different direction of rotation through simple change.
