DETAILED DESCRIPTION

[0026] Example 1

[0027] like Figures 1 to 5 As shown, a passive intelligent lock cylinder and key suitable for cabinet locks, the lock cylinder 1 is arranged inside the lock cylinder shell 2, and a locking bolt mechanism 3, an electrical component 4 and a control system 5 are provided in the cavity of the lock cylinder shell 2 below the lock cylinder 1. The locking column 301 passes through the lock cylinder shell 2 and is inserted into the locking hole 101 of the lock cylinder 1. The hexagonal key 6 is inserted into the keyhole of the lock cylinder 1. The signal contact 601 thereon is electrically connected to the locking bolt mechanism 3 and the control system 5 through the electrical component 4. The locking bolt mechanism 3 is controlled to drive the locking column 301 to retract, and the hexagonal key 6 drives the lock cylinder 1 to rotate and open the lock.

[0028] This application integrates the electronic structure of the smart lock core into the traditional cabinet lock core and key, and sets an electrical contact connected to the key inside the cylindrical lock core to facilitate obtaining external power for the passive lock core. The control component and the lock bolt component of the traditional mechanical structure are integrated into the lower end of the lock core. The mechanical structure is simple, durable and compactly arranged, so that the smart lock core and key of this application can be conveniently installed and used in a variety of cabinet locks.

[0029] In the preferred embodiment, the structure of the locking mechanism 3 is as follows: the lower end of the locking column 301 is connected to one side of the rack 302 through a connecting plate 306, and a driving motor 303 is provided on the other side of the rack 302, whose output shaft is connected to the gear 304, and the gear 304 is engaged with the front tooth portion of the rack 302, so that the driving motor 303 drives the locking column 301 to shuttle in the locking hole 101.

[0030] In the preferred embodiment, a T-shaped slider is provided on the rear side of the rack 302 , and a matching T-shaped slot is provided in the back plate 305 . The rack 302 is slidably connected to the inner wall of the cavity below the lock cylinder housing 2 through the back plate 305 .

[0031] After the locking mechanism 3 receives the control signal from the control system 5, the driving motor 303 drives the output shaft gear 304 to rotate through the electric energy obtained from the power connection component 4, and the gear 304 drives the rack 302 to move downward in the back plate 305, thereby driving one side locking column 301 to retract from the locking hole 101, thereby unlocking the rotation of the lock cylinder 1.

[0032] In the preferred embodiment, the structure of the power connection component 4 is as follows: at least two first power connection heads 402 are provided on the power connection seat 401, the bottom ends of the first power connection heads 402 are connected to the bottom of the blind hole of the power connection seat 401 through the first spring 403, and the first power connection heads 402 shuttle in the blind hole;

[0033] The power connection component 4 is arranged on one side above the control system 5 , and the drive motor 303 is arranged on the other side above the control system 5 .

[0034] The locking mechanism 3, the power connection component 4 and the control system 5 are closely arranged in the cavity of the lock core housing 2 below the lock core 1, which reduces the overall volume occupied by the lock core and improves the information and energy transmission efficiency between the components.

[0035] In a preferred embodiment, at least two conductive rings 7 are provided on the outer end of the lock core 1 close to the keyhole, and the first electrical terminal 402 passes through the lock core housing 2 and abuts against the conductive ring 7 .

[0036] In a preferred embodiment, at least two blind holes are provided on one side of the keyhole inside the lock core 1 , and a second electrical connector 8 is provided inside the blind hole. The bottom end of the second electrical connector 8 is connected to the bottom of the blind hole through a second spring 801 .

[0037] In a preferred embodiment, a wire is further provided at the bottom of the first power connector 402, one end of the wire is connected to the end of the first power connector 402, and the other end passes through the power socket 401 and is electrically connected to the locking mechanism 3 and the control system 5;

[0038] A conductive column 802 is further provided at the bottom end of the second electrical connector 8 , one end of the conductive column 802 is connected to the end of the second electrical connector 8 , and the other end is connected to the conductive ring 7 .

[0039] In a preferred embodiment, at least two signal contacts 601 are provided on one side of the hexagonal key 6 . The hexagonal key 6 is inserted into the keyhole of the lock cylinder 1 , and the end of the second power connector 8 rests against the signal contact 601 to supply power to the interior of the lock cylinder 1 .

[0040] The hexagonal key 6 is inserted into the keyhole of the lock cylinder 1, and electricity is transmitted to the control system 5 and the bolt mechanism 3 inside the lock cylinder 1 through multiple electrical contacts and electrical heads, activating the internal circuit of the passive lock cylinder. At the same time, the identity authentication is performed on the control system 5 through this circuit. After the hexagonal key 6 is successfully authenticated, the control system 5 is authorized to send an unlocking signal to the bolt mechanism 3. The lock can only be unlocked after the locking column 301 is fully retracted from the locking hole 101.

[0041] The control system 5 stores a certain amount of electrical energy when it is powered on. When the hexagonal key 6 is away from the lock body or the unlocking operation is completed, the locking column 301 is driven to insert into the locking hole 101, and the locking bolt mechanism 3 relocks the lock cylinder 1.

[0042] The power connection component 4 is buried inside the lock core 1 to reduce short circuit and damage. At the same time, it is small in size and compact in structure and can be set in the same plane as the keyhole. While ensuring the durability and sensitivity of the power connection part, the overall volume of the lock core 1 is reduced.

[0043] In the preferred embodiment, a polygonal hole is further provided in the middle of the hexagonal key 6 , and a polygonal column adapted thereto is provided in the keyhole in the middle of the lock cylinder 1 . The polygonal hole has an odd number of sides for distinguishing the direction of the signal contact 601 .

[0044] The hexagonal key head design increases the difficulty of key duplication, and the addition of a polygonal hole in the center further improves the security of the key. At the same time, the odd-numbered sides of the polygonal hole provide guidance for the insertion of the hexagonal key 6 into the lock cylinder 1, making it easy to distinguish between the top and the bottom, so that the end of the second contact 8 can correctly abut against the signal contact 601.

[0045] In the preferred embodiment, the rear end of the lock core housing 2 is provided with a stepped ring 201, and the rear end of the lock core 1 is provided with a matching annular groove 102. The stepped ring 201 is arranged in the annular groove 102 to limit the axial movement of the lock core 1;

[0046] The rear end of the lock core 1 is connected to the lock tongue 9.

[0047] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
