[0032] Example
[0033] Combination Figures 1 to 7 The present embodiment provides a passive lock with dual security authentication, including a passive lock 1 and a smart key 2. The passive lock 1 includes a lock body and a lock core. The lock body is equipped with a first control component, the lock core rotates with the lock body, and is provided with a socket. The smart key 2 includes a key body 21, a second control component, and a fingerprint recognition module and an encryption module electrically connected to the second control component. A plug 22 adapted to the socket is installed or formed on the key body 21. The first control component is configured to be electrically and communicatively connected to the second control component when the plug 22 is inserted into the socket, and to drive the electromagnetic structure in the lock body to unlock the lock after the dual security authentication formed by the fingerprint recognition module and the encryption module.
[0034] Exemplarily, the plug 22 is provided with electrical contacts, and after the plug 22 is inserted into the jack, it abuts against the connection contacts in the jack, so that the first control part is electrically connected and telecommunication connected with the second control part. When the fingerprint and key input by the user are authorized fingerprints and keys, the second control part sends an unlocking instruction to the first control part, so that the first control part drives the electromagnet to be energized to suck the iron core back and no longer block the rotation of the lock core. At this time, the smart key 2 can be rotated to drive the lock core to rotate relative to the lock body to achieve unlocking. For example, a gear slot is provided on the periphery of the lock core, and a spring is mounted on the iron core. When the smart key 2 is inserted into the jack and passes the double security authentication, the electromagnet is energized so that the iron core overcomes the spring elastic force and disengages from the gear slot. At this time, the smart key 2 is rotated to drive the lock core to rotate to achieve unlocking. When the smart key 2 is pulled out of the jack or has not passed the security authentication, the electromagnet loses power, and under the action of the spring, the iron core abuts against the gear slot to limit, and the lock core cannot rotate at this time. Among them, the other structures of the lock core are the same as those of the mechanical lock. The first control component and the second control component can be circuit boards. The circuit principles and structures of the fingerprint recognition module and the encryption module are existing technologies and will not be repeated here.
[0035] It should be noted that in this embodiment, a fingerprint recognition module and an encryption module are added to the traditional mechanical lock to form a double security authentication. The lock can only be unlocked when the fingerprint and password are entered correctly, otherwise the unlocking fails. Both pieces of information are indispensable, thereby improving the security of the lock. At the same time, the passive lock can open multiple locks with one smart key 2, which is convenient for the centralized management of keys of multiple devices. In addition, each unlocking of the smart key 2 is recorded, and the unlocking record can be saved and monitored in real time, making the use of the lock safer.
[0036] In summary, the dual security authentication function of the passive lock greatly increases the security of the lock, reduces the risk of the ATM device 3 being stolen, and maximizes the security level of the ATM device 3. If a criminal attempts to unlock the lock illegally, the unlocking will fail due to the mismatch of fingerprint information, password information, etc. In other embodiments, the passive lock can also be configured to feed back abnormal information to the background after the unlocking fails, thereby preventing the economic losses caused by the theft of the ATM device 3 in a timely manner.
[0037] In a preferred embodiment, the key body 21 is equipped with a plug 22 at one end, and the other end thereof is inclined outward and provided with a keyboard 23 for inputting a key, and the keyboard 23 is electrically connected to the encryption module. For example, the keyboard 23 is arranged on an inclined surface inclined downward and outward, so that the structure of the smart key 2 is more compact, and the volume is saved while ensuring that the user can clearly see each key when inputting the key from top to bottom.
[0038] Furthermore, a shoulder 24 is provided on the key body 21, which is configured on the same side as the plug 22 and has a size larger than that of the socket, for limiting the depth of the plug 22 inserted into the socket to avoid the situation where the plug 22 is not inserted into place or is inserted too far, resulting in poor contact of the contacts.
[0039] On the basis of the above embodiments, in an optional embodiment of the utility model, the smart key 2 also includes a battery built into the key body 21 and a charging socket 25 located on one side of the key body 21, and the battery and the charging socket 25 are both electrically connected to the second control unit. Among them, the battery can be a rechargeable battery such as a lithium battery, a nickel-metal hydride battery, etc., and the charging socket 25 is preferably a Type-C socket, so as to adapt to the type of existing charging cables and be able to find a suitable power cord at any time. In other embodiments, the charging socket 25 can be configured to have a charging function and a data transmission function, and the user imports and exports data through the charging socket 25, wherein the circuit principle is a prior art and will not be repeated here.
[0040] In a preferred embodiment, a sealing plug 26 that can be opened and closed is arranged on the charging socket 25. The sealing plug 26 is sealed with the inner periphery of the charging socket 25, and is provided with a mounting portion for connecting with the key body 21. The mounting portion is sleeved in the mounting hole of the key body 21, and is limited by the limiting boss 261 and the mounting hole, wherein the cross section of the limiting boss 261 along the mounting direction increases gradually. The sealing plug 26 is preferably made of silicone or rubber. When installing, the limiting boss 261 can be pulled in from the inside of the mounting hole to prevent the sealing plug 26 from falling off the key body 21. At the same time, the outer peripheral size of the sealing plug 26 is larger than the size of the charging socket 25, and it will not fall out without external pulling force. The setting of the sealing plug 26 realizes dustproof and waterproof of the charging port, thereby improving the life of the charging socket 25, and further ensuring the overall service life of the smart key 2.
[0041] In another embodiment, a switch button 211 is disposed on the front of the key body 21, and the second control element is triggered to open and close via the switch button 211. When the smart key 2 needs to be used, the switch button 211 needs to be pressed to activate the second control element, and the switch button 211 needs to be pressed to close the second control element when not in use to save power.
[0042] Furthermore, the fingerprint recognition module includes a fingerprint recognition window 27, which is disposed on the front side of the key body 21 and between the switch button 211 and the keyboard 23, so as to facilitate fingerprint input by the user.
[0043] Preferably, the key body 21 is in an elongated shape, and a force-applying portion is provided on at least one side of the key body 21, and the force-applying portion is convex or concave along the outer surface of the key body 21. In one embodiment, the force-applying portion is provided as an anti-slip pattern 212, and is provided on the front and back of the key body 21, so as to increase the friction force of the user when inserting and removing the smart key 2, and also facilitate the rotation of the smart key 2.
[0044] In other embodiments, a hanging ear 213 is provided on the back of the key body 21, and an assembly hole for a hanging rope or a buckle to pass through is provided on the hanging ear 213. For example, inserting a hanging rope on the hanging ear 213 can facilitate the hanging and storage of the smart key 2, and the management of the smart key 2 can also be achieved by inserting hanging ropes of different colors or different marks, and the present invention is not limited to this and is not specifically limited.
[0045] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
