The on-off state of the locking mechanism is controlled by the clutch mechanism, and when the clutch mechanism is on, a user can operate the locking mechanism to open and close the lock; when the clutch mechanism is disconnected, namely the locking action is realized, the user can operate the key 24 to perform the back locking action.
The anti-locking mechanism comprises a clockwork spring 21, a ratchet wheel 22, a pawl 23 and a key 24, the ratchet wheel 22 and the clockwork spring 21 are installed on the inner rotating shaft 13, the inner rotating shaft 13 rotates to drive the clockwork spring 21 to rotate, the pawl 23 is matched and fixed with the ratchet wheel 22, unidirectional rotation and post-fixing are achieved, and therefore the clockwork spring 21 is in an energy storage state.
The key 24 is disposed at the exposed ends of the inner rotating shaft 13 and the outer rotating shaft 14, and is configured to push the inner rotating shaft 13 to displace, so that the ratchet 22 is separated from the pawl 23, and the spring 21 resets to rotate the inner rotating shaft 13 and drive the shifting block 12 to rotate, thereby implementing a back lock.
The working principle of the intelligent lock cylinder 100 of the invention is as follows:
the identity recognition module recognizes the identity of a user and transmits an instruction to the control module, the clutch mechanism is controlled to be connected with the inner rotating shaft 13 and the outer rotating shaft 14, at the moment, the user can twist the outer rotating shaft 14 to drive the shifting block 12 to unlock, meanwhile, the inner rotating shaft 13 drives the clockwork spring 21 to rotate, and the ratchet wheel 22 is matched and fixed with the pawl 23, so that the clockwork spring 21 is in an energy storage state;
after the preset time is reached, the control module controls the clutch mechanism to disconnect the inner rotating shaft 13 and the outer rotating shaft 14, so that locking is realized;
the key 24 is pressed to push the inner rotating shaft 13 to displace, so that the ratchet wheel 22 is separated from the pawl 23, and the clockwork spring 21 enables the inner rotating shaft 13 to rotate and drives the shifting block 12 to rotate, thereby realizing the counter locking.
Therefore, the user does not need to perform the back locking through a key or software, when the user forgets to carry the key or the mobile phone, the automatic back locking is completed by pressing the key 24, the use is convenient, and the family property and the personal safety of the user are guaranteed.
Further, the latch mechanism further includes a pair of door handles 10, the door handles 10 are respectively connected to the inner rotating shaft 13 and the outer rotating shaft 14, and a user can control the movement of the inner rotating shaft 13 and the outer rotating shaft 14 through the door handles 10, thereby facilitating the operation.
Further, a first return spring 15 is sleeved outside the inner rotating shaft 13, and after the spring 21 releases the stored energy, the first return spring 15 pushes the inner rotating shaft 13 to return to the initial position so as to enable the ratchet wheel 22 and the pawl 23 to be combined again, and meanwhile, the key 24 located in the door is reset, so that the next automatic back locking operation is facilitated.
Further, a second return spring 16 is sleeved outside the outer rotating shaft 14, when the clutch mechanism is in the on state, the door handle 10 located outside the door is manually twisted to integrate the inner rotating shaft 13 and the outer rotating shaft 14, and the button 24 located outside the door is reset under the action of the second return spring 16, so that the next automatic back locking operation is facilitated.
In this embodiment, the number of the ratchet wheels 22 is two, and the ratchet wheels are arranged around the periphery of the inner rotating shaft 13 at intervals, so that the clamping stability of the ratchet wheels 22 and the pawls 23 can be improved.
As an embodiment, clutching mechanism includes drive arrangement, transmission arm and sleeve 33, sleeve 33 cover in outer axis of rotation 14, the both ends of transmission arm respectively with drive arrangement with sleeve 33 fixed connection, drive arrangement drives sleeve 33 takes place the displacement, so that sleeve 33 with interior axis of rotation 13 joint or break away from.
When the sleeve 33 is clamped with the inner rotating shaft 13, the outer rotating shaft 14 is butted with the inner rotating shaft 13, and then the door handle 10 is rotated to rotate the shifting block 12, so that unlocking is realized.
When the sleeve 33 is disengaged from the inner rotating shaft 13, the outer rotating shaft 14 is separated from the inner rotating shaft 13, the door handle 10 is idle and cannot be unlocked by rotating the door handle 10 located outside the door, and the shifting block 12 is always connected to the inner rotating shaft 13 and can be unlocked by rotating the door handle 10 located inside the door.
In this embodiment, the driving device may adopt a motor and a lead screw connected to the motor, and the driving arm is connected to the lead screw, so that the operation is stable and automatic operation is realized.
Specifically, as shown in fig. 4, the present invention further includes a U-shaped arm 17 disposed outside the intelligent lock cylinder 100, and the intelligent lock cylinder 100 is fixed to a door by a screw 18. During installation, only need insert earlier intelligent lock core 100 back, aim at screw 18 with U type arm 17 locking according to actual door thickness, U type arm 17 can hide the installation, and can the adjusting position, just so can realize that intelligent lock core 100's inside and outside length is adjustable to match the demand of different door thicknesses.
The intelligent lock cylinder 100 is designed based on the lock cylinder shells of the existing standard national standard, american standard and European standard, and the intelligent lock cylinder 100 can be replaced only by disassembling the screw 18, so that the intelligent improvement of the traditional lock cylinder is completed.
In the present embodiment, an automatic delay module is provided in the control module, and is configured to control the clutch mechanism to disconnect the inner rotating shaft 13 from the outer rotating shaft 14. When the clutch mechanism enables the locking mechanism to be in a connected state, if the locking mechanism is not further operated within a preset time, the automatic delay module drives the clutch mechanism to enable the locking mechanism to be in a disconnected state, at the moment, unlocking operation cannot be carried out, and the use safety of the intelligent lock cylinder 100 is improved.
