[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is described more comprehensively below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In one embodiment, see Figure 1 , a smart lock core is provided, which includes a control device ⑦, an electronic latch ⑤ and a lock core body, the control device ⑦ is connected to the electronic latch ⑤, the electronic latch ⑤ is arranged on the lock core body, the control device ⑦ is used to send a control instruction to the electronic latch ⑤ according to the received instruction, the electronic latch ⑤ is used to adjust its own position according to the control instruction, and the lock core body can adjust the locking state based on the position change of the electronic latch ⑤. The user can control the locking state of the lock core body by sending an instruction to the control device ⑦, and then the control device ⑦ sends the control instruction to the electronic latch ⑤. When the lock core body is in the unlocked state, the user can open the door smoothly, and the smart lock core can be unlocked without carrying a mechanical key, avoiding the situation where the user forgets to bring the key and cannot enter the door, and improving the convenience of using the smart lock core.

[0026] Specifically, the locked state of the lock core body refers to the locked state of some or all of the components of the lock core body. The change in the position of the electronic pin ⑤ can achieve the limitation or cancellation of the limit on the lock core body. When the lock core body is limited, some or all of the components of the lock core body are locked with each other and the unlocking operation cannot be performed. When the lock core body is cancelled, the various components of the lock core body can be moved as needed to facilitate the subsequent unlocking operation. The control device ⑦ is electrically connected to the electronic bolt ⑤. The control device ⑦ can receive instructions and send control instructions to the electronic bolt ⑤ according to the received instructions. The electronic bolt ⑤ is set in the lock core body. The specific setting position of the electronic bolt ⑤ will be different according to the different structures of the lock core body. After receiving the control instruction, the electronic bolt ⑤ can adjust its own position according to the received control instruction, specifically adjust its relative position with the lock core body. Taking the through hole opened in the lock core body as an example, when the control instruction received by the electronic bolt ⑤ is an unlocking instruction, the electronic bolt ⑤ pops out of the through hole to put the lock core body in an unlocked state, and the user can unlock the lock through subsequent operations, such as turning the knob ② to unlock the lock. When the control instruction received by the electronic bolt ⑤ is a locking instruction, the electronic bolt ⑤ is inserted into the through hole of the lock core body to put the lock core body in a locked state, and the user cannot unlock the lock. It can be understood that in other embodiments, the lock core body can also be of other structures, and correspondingly, the setting relationship between the electronic latch ⑤ and the lock core body can also be different, as long as the change of the setting position of the electronic latch ⑤ can realize the switching of the unlocking and locking states of the lock core body.

[0027] After receiving the instruction, the control device ⑦ analyzes the received instruction, and then sends a control instruction corresponding to the function of the received instruction to the electronic bolt ⑤, so that the electronic bolt ⑤ adjusts the unlocking or locking state of the lock core body by changing its own position, so that the smart lock core can be unlocked or locked according to the received instruction, thereby realizing non-mechanical key unlocking.

[0028] The source of the instructions received by the control instruction is not unique. For example, the control device ⑦ can receive instructions from other devices and generate control instructions based on them. For example, when the smart lock core also includes a voice receiving device, the voice receiving device is connected to the control device ⑦, and the voice receiving device sends the collected voice instructions to the control device ⑦. The control device ⑦ can generate control instructions based on the voice instructions received by the voice receiving device. When the control device ⑦ recognizes that the voice signal has a high degree of match with the keyword "unlock" stored in the database, the control device ⑦ sends an unlocking instruction to the electronic bolt ⑤ to unlock the lock core body. When the control device ⑦ recognizes that the voice signal has a high degree of match with the keyword "lock" stored in the database, the control device ⑦ sends a locking instruction to the electronic bolt ⑤ to lock the lock core body. Alternatively, when the smart lock core also includes an input device, the input device is connected to the control device ⑦, and the user can input instructions through the input device. After receiving the instructions from the input device, the control device ⑦ generates a corresponding control instruction to control the lock core body. The input device can be a key input device or a touch input device. It can be understood that in other embodiments, the source of the instruction received by the control device ⑦ may also be other sources, which will not be repeated here.

[0029] The type of control device ⑦ is not unique, for example, it can be CPLD (Complex Programmable Logic Device), FPGA (Field-Programmable Gate Array) or single-chip microcomputer. CPLD is a digital integrated circuit that users can construct logic functions according to their needs. As control device ⑦, it has the advantages of flexible programming, high integration, short design and development cycle, wide application range, low design and manufacturing cost, strong confidentiality, popular price, etc., and fast speed and high time predictability. FPGA is based on logic gates and triggers, which can realize parallel task processing in the true sense. As control device ⑦, it has low design cost and high working stability. Single-chip microcomputer integrates various functional components on one chip, adopts bus structure internally, reduces the connection between chips, greatly improves the reliability and anti-interference ability of single-chip microcomputer, and thus has the advantages of small size, simple structure and high reliability as control device ⑦. It can be understood that in other embodiments, control device ⑦ can also be of other types as long as those skilled in the art believe that it can be realized.

[0030] In one embodiment, see Figure 2 The electronic latch ⑤ includes an electromagnetic component 51, a motor rotating component 52, a latch 53 and an elastic element 54. A hollow cavity is opened in the latch 53. The motor rotating component 52 and the elastic element 54 are both arranged in the hollow cavity. The electromagnetic component 51 is fixedly connected to the motor rotating component 52. The motor rotating component 52 is arranged in contact with one side of the elastic element 54, and the other side of the elastic element 54 is arranged in contact with the latch 53. The electromagnetic component 51 is electrically connected to the control device ⑦, and the latch 53 is arranged on the lock core body.

[0031] Specifically, the structure of the electronic latch ⑤ is not the only one. In the present embodiment, a hollow cavity is provided in the latch 53, and the motor rotor 52 and the elastic element 54 are both arranged in the hollow cavity, which can reduce the volume. The electromagnetic component 51 is fixedly connected to the motor rotor 52, and the movement of the electromagnetic component 51 can drive the motor to move. The motor rotor 52 is arranged in contact with one side of the elastic element 54, and the other side of the elastic element 54 is arranged in contact with the latch 53. The deformation of the elastic element 54 will change the position of the latch 53. The electromagnetic component 51 is electrically connected to the control device ⑦, and the latch 53 is arranged on the lock core body. The control device ⑦ sends a control command to the electromagnetic component 51. After receiving the control command, the electromagnetic component 51 starts to move. The direction of movement is different according to the received control command. The electromagnetic component 51 is fixedly connected to the motor rotating component 52. The electromagnetic component 51 transmits the movement to the motor rotating component 52. The motor rotating component 52 is arranged in contact with one side of the elastic element 54. The movement of the motor rotating component 52 will drive the elastic element 54 to compress or stretch, thereby driving the latch 53 arranged in contact with the other side of the elastic element 54 to move in the deformation direction of the elastic element 54, realizing the change of the position of the latch 53, so that the lock core body adjusts the unlocking state or the locking state. It can be understood that in other embodiments, the electronic latch ⑤ can also be other structures, as long as the technicians in this field think it can be realized.

[0032] In one embodiment, the electromagnetic component 51 is a motor. The type of the electromagnetic component 51 is not unique, as long as it can produce corresponding movement according to the received control instruction. In this embodiment, taking the electromagnetic component 51 as a motor as an example, the motor is connected to the control device ⑦, and can receive the control instruction transmitted by the control device ⑦, and forward or reverse according to the received control instruction. The motor is fixedly connected to the motor rotating member 52, and when the motor rotates forward or reverses, it drives the motor rotating member 52 to move. Specifically, the connection method between the motor and the motor rotating member 52 is not unique. In this embodiment, the motor and the motor rotating member 52 can be connected into one body by riveting, so that the connection strength between the motor and the motor rotating member 52 is good, the use cost is low, and it is easy to use. It can be understood that in other embodiments, the motor and the motor rotating member 52 can also adopt other connection methods, as long as those skilled in the art believe that it can be achieved.

[0033] In one embodiment, the electromagnetic component 51 is an electromagnet. In this embodiment, the electromagnetic component 51 is an electromagnetic component 51, and the electromagnetic component 51 can induce a magnetic field according to the received electrical signal, and can induce magnetic fields in different directions according to different received control instructions, thereby driving the motor rotating component 52 connected to the electromagnet to move in different directions, and the motor rotating component 52 is connected to the elastic element 54. The movement of the motor rotating component 52 in different directions will drive the elastic element 54 to compress or stretch, thereby driving the latch 53 connected to the elastic element 54 to move in the deformation direction of the elastic element 54, realizing the change of the position of the latch 53, so that the lock core body adjusts the unlocking state or the locking state. It can be understood that in other embodiments, the electromagnetic component 51 can also be other types of devices, as long as those skilled in the art believe that it can be achieved.

[0034] In one embodiment, the elastic element 54 is a spring. The type of the elastic element 54 is not unique, as long as it undergoes recoverable stretching or compression deformation according to the movement of the motor rotating member 52. In this embodiment, taking the elastic element 54 as a spring as an example, one side of the spring is connected to the motor rotating member 52, and the other side is connected to the latch 53. When the motor rotating member 52 moves, the spring is driven to be compressed and released, and the latch 53 moves up and down along the direction of the spring deformation under the action of the compression and release of the spring. Through the up and down movement of the latch 53, the position of the latch 53 changes, and the relative position of the latch 53 and the lock core body changes. Taking the latch 53 as an example, when the latch 53 pops out of the through hole, the lock core body is in an unlocked state, and when the latch 53 is inserted into the through hole of the lock core body, the lock core body is in a locked state. It can be understood that in other embodiments, the lock core body can also be other structures, and correspondingly, the setting relationship between the latch 53 and the lock core body can also be different. It can be understood that in other embodiments, the elastic element 54 can also be other types of devices, as long as those skilled in the art believe that it can be achieved.
