Description

Technical Field

[0001] This utility model belongs to the field of computer lock technology, and specifically refers to a passive communication computer lock. Background Technology

[0002] Traditional combination locks suffer from the security problem of easily observable passwords, especially in public places or situations requiring high security, where password confidentiality is paramount. One type of product is the laptop lock, also known as a notebook anti-theft lock, specifically designed for portable electronic devices such as laptops and tablets. One side of the lock has a keyhole for inserting the electronic device to lock or unlock it, while the other side typically has a high-strength cord or similar object to secure the lock in a specific location / area. Because the locking mechanism can only enter and exit the keyhole when the lock is in the unlocked state, inserting the computer lock into the electronic device's keyhole may still display the correct password. The user must then manually rotate the dials to scramble the password, resulting in a poor user experience and the risk of financial loss due to the user forgetting to scramble the dials.

[0003] With the development of technology, traditional mechanical locks are gradually being replaced by electronic smart locks. Compared with mechanical locks, electronic smart locks have the following advantages: (1) They are easy to carry; (2) They can transmit information to smart terminals, while traditional mechanical locks cannot record the time of opening and closing the lock, who opened the lock, etc.; (3) The key is not easy to be copied, which greatly improves the security of the lock.

[0004] Based on the many advantages of electronic smart locks, the inventors hope to upgrade existing mechanical computer locks and improve them into passive locks. Utility Model Content

Detailed Implementation

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] refer to Figures 1 to 3 As shown, this utility model discloses a passive communication computer lock, including a computer lock 100 and an electronic key 200; The computer lock 100 includes a lock body 101, a main board 102, a motor 103, a locking assembly 104, and a bolt 105. The main board 102 and the motor 103 are disposed inside the lock body 101 and are electrically connected. The main board 102 is provided with a first conductive plate 1021 and a second conductive plate 1022. The main board 102 is grounded by contacting the lock body 101 through the first conductive plate 1021. The locking assembly 104 is installed on the surface of the lock body 101 and is used to insert into the lock hole of electronic devices (such as laptops and tablets) to achieve theft prevention. The bolt 105 is driven by the motor 103 to move and cooperate within the lock body 101 and is linked with the locking assembly 104 to change the locking and unlocking state of the locking assembly 104. When the bolt 105 is moving, it contacts or separates from the second conductive plate 1022. The electronic key 200 connects to the motherboard 102 via wireless (e.g., NFC) or contact and is powered by it.

[0023] Through the above scheme, this utility model uses the electronic key 200 to input unlocking or locking permissions and supply power to the mainboard 102 of the computer lock 100, so that it controls the working state of the motor 103 and drives the bolt 105 to move within the lock body 101, thereby changing the locking and unlocking state of the locking component 104, realizing the opening and closing of the lock through passive communication, that is, realizing the transformation of the computer lock into a passive computer lock. The passive computer lock has the advantages of small size and convenient use. It can realize the opening and closing of multiple locks after one electronic key 200 is managed and authorized, and can use the electronic key 200 to record the opening and closing records.

[0024] Meanwhile, this utility model can form the following signal circuit: the main board 102 is provided with a first conductive plate 1021 and a second conductive plate 1022. The first conductive plate 1021 is always connected to the lock body 101 and grounded. The second conductive plate 1022 does not directly contact the lock body 101. Only when the bolt 105 moves into place (for example, when locking is completed) does the bolt 105 contact the second conductive plate 1022. Then, the bolt 105 forms a circuit with the lock body 101 and the first conductive plate 1021, and provides locking / unlocking signals to ensure that the lock is unlocked / locked in place and that the relevant actions can be recorded.

[0025] The following are specific embodiments of the present invention.

[0026] The output end of the aforementioned motor 103 is coaxially connected to a rotating shaft 106, and a protrusion 1061 is provided on the circumferential surface of the rotating shaft 106. The locking tongue 105 is slidably fitted inside the lock body 101 along the axis of the motor 103, and its end near the motor 103 is sleeved on the rotating shaft 106, and is provided with a spiral groove 1051 for the protrusion 1061 to move and engage. Thus, the locking tongue 105 can be driven to move axially along the axis of the motor 103, thereby linking the opening and closing state of the locking assembly 104.

[0027] Furthermore, the aforementioned locking assembly 104 includes a lock head 1041 and a pair of latching blocks 1042; one end of each latching block 1042 is disposed within the lock head 1041, and the other end is provided with a latch 1043 for hooking onto the inner wall of the lock hole; the end face of the latch 105 facing away from the motor 103 is provided with a locking shaft 1052 that is movably inserted into the lock head 1041 and passes between the two latching blocks 1042; when the locking shaft 1052 is inserted between the two latching blocks 1042, the two latches 1043 cannot be moved. Thus, the motor 103 can drive the latch 105 to move axially so that the locking shaft 1052 is inserted into or disengaged from the locking assembly 104, thereby linking the opening and closing states of the locking assembly 104.

[0028] Meanwhile, the peripheral surface of the aforementioned latch 105 is provided with a latch contact 1053 that can movably abut against the second conductive sheet 1022.

[0029] Secondly, one end of the second conductive piece 1022 is soldered to the circuit of the main board 102, and the other end is not in direct contact with the lock body 101. Furthermore, an insulating sheet 107 is provided on the side of the second conductive piece 1022 that faces away from the lock tongue contact 1053, ensuring that even after the lock tongue 105 abuts against the second conductive piece 1022, the second conductive piece 1022 is not in direct contact with the lock body 101.

[0030] The surface of the electronic key 200 is provided with at least one magnetic electrode 201; the surface of the lock body 101 is provided with electrode contacts 108 corresponding to the magnetic electrode 201, and the electrode contacts 108 are electrically connected to the main board 102.

[0031] Furthermore, the aforementioned motherboard 102 is provided with a third conductive sheet 1023 for contact with the electrode contacts 108.

[0032] Secondly, the lock body 101 is provided with a motor mounting base 109 that cooperates with the motor 103. A gasket 110 is provided between the motor mounting base 109 and the lock body 101, and a third conductive sheet 1023 is fitted between the motor mounting base 109 and the gasket 110. The gasket 110 is made of plastic and is used to install the electrode contacts 108 and to achieve insulation.

[0033] The lock body 101 includes a first housing 101a and a second housing 101b that are detachably connected, which facilitates the disassembly and assembly of internal components.

[0034] The working principle of this utility model is shown below.

[0035] Unlock description: After obtaining unlocking authorization, the electronic key 200 connects and communicates with the electrode contacts 108 of the lock body 101 via the magnetic electrode 201. After successful matching, the main board 102 obtains unlocking authorization, and the motor 103 drives the rotating shaft 106 to rotate. The two protrusions 1061 on the rotating shaft 106 are respectively locked on the two spiral grooves 1051 of the bolt 105. When the rotating shaft 106 rotates, it drives the bolt 105 to move backward through the spiral grooves 1051. The lock shaft 1052 disengages from the locking assembly 104, the locking block 1042 retracts, and the computer lock 100 can be removed from the computer's keyhole to achieve unlocking. At the same time, the bolt contacts 1053 and the second conductive piece 1022 of the bolt 105 disengage, the circuit is broken, and the unlocking signal is transmitted to the electronic key 200. The indicator light of the electronic key 200 will flash to indicate that the unlocking is successful, and the user can remove the electronic key 200.

[0036] Lock description: After obtaining locking permission, the electronic key 200 connects and communicates with the electrode contact 108 of the lock body 101 via the magnetic electrode 201. After successful matching, the main board 102 obtains locking permission, the motor 103 rotates, driving the rotating shaft 106 to rotate. The rotating shaft 106 drives the bolt 105 to move forward, and the locking shaft 1052 inserts into the locking assembly 104 and opens the latch 1042. At this time, the computer lock 100 cannot be removed from the computer's keyhole, thus achieving locking. At the same time, the bolt contact 1053 of the bolt 105 contacts the second conductive plate 1022 to form a circuit signal. At this time, the locking signal is transmitted to the electronic key 200, and the indicator light of the electronic key 200 will flash to indicate that the locking is successful. The user can then remove the electronic key.

[0037] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
