In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0039] See also Figure 1 and Figure 2 The utility model provides a lock core, which can be selectively connected to an electronic key. The lock core includes a lock core body 1, a center contact 2 and a side contact 3. The lock core body 1 is provided with a docking groove 11 at one end facing the outside for connecting with the electronic key; the center contact 2 is arranged in the docking groove 11 and is concentric with the docking groove 11; the side contact 3 is circumferentially arranged around the center contact 2.
[0040] In this embodiment, one end of the lock core body 1 is connected to the lock body (not shown in the figure), and the docking groove 11 is provided at the end of the lock core body 1 away from the lock body (ie, the end facing the outside).
[0041] In this way, when the electronic key is inserted into the docking slot 11 and connected to both the center contact 2 and the side contact 3, the center contact 2 and the side contact 3 work together to transmit stable current and signals and avoid poor contact; the side contact 3 is circumferentially arranged around the center contact 2, which can facilitate the electronic key to be inserted into the docking slot 11 at multiple angles and to simultaneously abut against the center contact 2 and the side contact 3.
[0042] See also Figure 2 In some embodiments, the side contact 3 is a circular ring structure. Further, the diameter of the center contact 2 is equal to the width of the side contact 3, and the side wall of the center contact 2 facing the outside is flush with the side wall of the side contact 3 facing the outside.
[0043] In this way, when the electronic key is inserted into the docking slot 11 at any angle, it can be connected with the central contact 2 and the side contact 3 at the same time, which is convenient for the operator to quickly unlock or lock the door and improve the unlocking efficiency.
[0044] It can be understood that the diameter of the center contact 2 and the width of the side contact 3 can be adjusted according to actual needs, and the width of the side contact 3 can also be larger than the diameter of the center contact 2; six side contacts 3 can also be provided, and the six side contacts 3 are respectively provided corresponding to the side walls of the hexagonal groove. The shape of the side contact 3 can also be adjusted according to actual needs, so that the electronic key can stably transmit current and signals when it abuts against the center contact 2 and the side contact 3, which will not be elaborated here.
[0045] See also Figure 2 In some embodiments, the docking groove 11 is a hexagonal groove.
[0046] In this way, after the electronic key is inserted into the docking slot 11, the position of the electronic key in the docking slot 11 can be limited, so that the electronic key is not easily offset or rotated when it abuts against the center contact 2 and the side contact 3, thereby affecting the normal unlocking or locking process or even scratching the surface of the center contact 2 and the side contact 3.
[0047] See also Figure 2 In some embodiments, a circuit board 12 is disposed inside the lock core body 1. The circuit board 12 is respectively connected to the center contact 2 and the side contact 3. The circuit board 12 is communicatively connected to a control module (not shown in the figure) for sending an unlocking or locking signal.
[0048] Among them, see Figure 3 The circuit board 12 is a PCB (Printed Circuit Board) board, which is fixedly connected to the lock core body 1. The lock core also includes two connecting columns 4. The ends of the two connecting columns 4 facing the outside are respectively connected to the center contact 2 and the side contact 3, and the other ends are connected to the circuit board 12 for transmitting current and signals to the circuit board 12.
[0049] In this way, when the electronic key abuts against the center contact 2 and the side contact 3, the signal emitted by the electronic key can be transmitted to the circuit board 12 through the connecting column 4. The circuit board 12 transmits a control signal to the lock core body 1 to control the locking or unlocking of the lock body, thereby improving the response efficiency. Compared with the traditional mechanical lock, the electronic key only needs to be inserted into the docking slot 11 during the unlocking process, thereby reducing the operation time and difficulty.
[0050] See also Figure 1The utility model also provides an electronic key adapted to the lock core, the electronic key comprising a housing 5, a docking portion 6, a center contact 62, at least one side contact 63 and a communication module (not shown in the figure), the docking portion 6 is arranged at one end of the housing 5, and the shape of the outer wall of the docking portion 6 is adapted to the shape of the docking groove 11. The center contact 62 is connected to the docking portion 6, and is used to selectively abut against the center contact 2. The side contact 63 is arranged on one side of the center contact 62, and is used to selectively abut against the side contact 3. The communication module is connected to the center contact 62 and the side contact 63 respectively.
[0051] Among them, the shell 5 is a strip structure with semicircular ends. The docking part 6 is arranged at one end in the length direction of the shell 5. The cross-section of the end of the docking part 6 facing away from the shell 5 is hexagonal, so that the docking part 6 can be plugged into the docking slot 11; the communication module is communicatively connected with the side contact 63 and the center contact 62, and is used to transmit signals to the side contact 63 and the center contact 62.
[0052] In this way, when the docking part 6 is inserted into the docking slot 11 at any angle, the side contact 63 can be abutted against the side contact 3, and the center contact 62 can be abutted against the center contact 2, thereby realizing the transmission of signals and currents, improving operating efficiency, and facilitating rapid unlocking or locking operations; the communication module can transmit signals to the circuit board 12 through the side contacts 63 and the center contact 62 to control the lock body.
[0053] It is understandable that the number of the side contacts 63 can be adjusted according to actual needs, and no further enumeration is given here. In the present embodiment, only one side contact 63 is provided.
[0054] See also Figure 4 In some embodiments, the docking portion 6 is provided with a connecting groove 61, the connecting groove 61 is coaxial with the docking portion 6, and the center contact 62 and the side contact 63 are both arranged in the connecting groove 61, and the height of the center contact 62 and the height of the side contact 63 are both less than the depth of the connecting groove 61.
[0055] In this embodiment, the connection groove 61 is a circular groove, and one end of the center contact 62 facing the housing 5 is concentric with the inner wall of the connection groove 61. A boss (not shown in the figure) matching the circular groove is correspondingly provided in the docking groove 11.
[0056] In this way, the center contact 62 and the side contact 63 are arranged in the connecting groove 61, which can protect the center contact 62 and the side contact 63 and make it difficult for the center contact 62 and the side contact 63 to collide with the outside world and thus be damaged; the electronic key and the lock core are connected to the boss through the connecting groove 61, which can further enhance the stability during connection and avoid poor contact.
[0057] See also Figure 4 In some embodiments, the docking portion 6 is integrally formed with the shell 5 .
[0058] In this way, the connection strength between the docking portion 6 and the housing 5 can be improved, so that the electronic key is not easily broken when connected to the lock core, thereby affecting the normal unlocking and locking work.
[0059] See also Figure 4 In some embodiments, the housing 5 is also connected to a Bluetooth module (not shown in the figure) and a fingerprint module (not shown in the figure). In this embodiment, the Bluetooth module and the fingerprint module are both connected to the communication module.
[0060] In this way, the Bluetooth module can connect the electronic key to the mobile phone and perform identity authentication, and the fingerprint module can further limit the conditions for unlocking or locking, thereby improving the security of the electronic key.
[0061] It is understandable that the communication connection between the Bluetooth module and the mobile phone and the transmission of the unlocking or locking signal by the fingerprint module to the circuit board 12 are both existing technologies and will not be elaborated here.
[0062] Further, see Figure 5 A charging port 51 is provided at one end of the shell 5 away from the docking portion 6. A battery (not shown in the figure) is arranged inside the shell 5. The battery is charged through the charging port 51, which can stably deliver current to the Bluetooth module, fingerprint module, communication module, etc.
[0063] See also Figure 1 In some embodiments, the outer wall of the housing 5 is further provided with an indicator light (not shown in the figure) for displaying the power of the electronic key, and the outer wall of the housing 5 is further provided with a display screen 52. Further, the electronic key further includes a switch 7, which is arranged on the side wall of the housing 5. The indicator light and the display screen 52 are arranged on the same side of the housing 5, and both the indicator light and the display screen 52 are connected to the battery.
[0064] In this way, the display screen 52 and the indicator light can both display the battery power, which is convenient for the operator to observe the status of the electronic key in time, thereby improving the convenience of using the electronic key.
[0065] It is understandable that the installation position and specific structure of the indicator light, display screen 52, and switch 7 can be adjusted according to actual needs; the display screen 52 can also be connected to the Bluetooth module, fingerprint module, and communication module to display other relevant information (for example, whether the Bluetooth function is turned on), which will not be listed in detail here.
[0066] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
