DETAILED DESCRIPTION

[0027] like Figures 1 to 7 As shown, an electronic mechanical universal intelligent passive mechanical lock core, the key hole inside the lock core 2 is connected to the blind hole at the end, a motor 7 is arranged inside the blind hole inside the lock core 2, the output end of the motor 7 is connected to the drive disk 10, one side of the drive disk 10 is hinged to one end of the connecting rod 13, the other end of the connecting rod 13 is hinged to the end of the pin 12, the pin 12 is slidably connected to the lock core 2, and the pin 12 passes through the lock core 2 and is inserted into the pin hole 101 inside the lock body 1; a synchronization strip 8 is also arranged at the end of the lock core 2, and the smart key 4 pushes the synchronization strip 8 to connect with the lock tongue 3.

[0028] The lock core 2 is a cylindrical structure, and a motor 7 and a pin 12 are integrated inside the lock core 2. The overall structure is simple and the installation method is simple. The motor drives the drive disk 10 to rotate, and the drive disk 10 drives the pin 12 to extend and retract through the connecting rod 13. The pin 12 comes out of the pin hole 101 inside the lock body 1, and the smart key 4 can rotate the lock core 2 to unlock.

[0029] The lock core 2, as the core component of the lock, adopts a cylindrical structure, with a key hole arranged inside and connected to the blind hole at the end. This design allows the key to directly act on the mechanical structure inside the lock core, and also provides space for the integration of passive electronic components.

[0030] The motor 7 is located in the blind hole inside the lock core 2, which is a key element of the passive design. The motor starts after receiving energy from the smart key 4 and drives the mechanical action inside the lock core.

[0031] The driving disc 10 is connected to the output end of the motor 7, and the motor drives the driving disc to rotate when the motor is running. The rotation of the driving disc is converted into the linear motion of the connecting rod, thereby realizing the transmission and conversion of power.

[0032] One end of the connecting rod 13 is hinged to the driving disc 10, and the other end is hinged to the end of the pin 12. The connecting rod serves as a transmission mechanism to convert the rotational motion of the driving disc into the reciprocating motion of the pin.

[0033] The pin 12 is slidably connected to the lock core 2 and can be inserted into the pin hole 101 inside the lock body 1. The pin is driven by the motor to achieve telescopic movement, thereby controlling the locking and unlocking states of the lock.

[0034] The synchronization bar 8 is arranged at the end of the lock core 2, and has an interactive relationship with the smart key 4 and the lock tongue 3. When the smart key acts on the synchronization bar, it may trigger the linkage of the lock tongue, ensuring the synchronization of the rotation of the lock core and the action of the lock tongue.

[0035] The smart key 4 is a passive key with electronic identity verification function. It not only matches the internal mechanical structure of the lock cylinder through its physical shape, but also provides temporary power when inserted into the lock cylinder 2, activates the motor and performs identity verification. After successful verification, the smart key can rotate the lock cylinder to unlock.

[0036] When the smart key 4 is inserted into the lock cylinder 2, data is obtained from the smart key 4 through passive electronic technology, and electronic identity verification is performed at the same time. After the verification is passed, the smart key authorization motor 7 is started.

[0037] After receiving the start signal, the motor 7 starts to run, driving the drive disk 10 to rotate. The rotating drive disk converts the rotational motion into linear motion through the connecting rod 13, pushing the pin 12 to slide in the lock cylinder. When the pin is extended, its end is separated from the pin hole 101 inside the lock body 1, releasing the mechanical restriction on the rotation of the lock cylinder.

[0038] After the smart key 4 is successfully authenticated and the pin is extended, it can directly or indirectly rotate the lock cylinder 2 by acting on the synchronization bar 8. During the rotation of the lock cylinder, the lock tongue moves with the lock cylinder through the connection with the lock tongue 3 or the preset mechanical linkage, thereby realizing the opening of the door lock.

[0039] When the smart key is away from the lock body or the unlocking operation is completed, the passive electronic system stops working, the motor is powered off, the pin is automatically retracted under the action of a reset device such as a spring, and reinserted into the pin hole of the lock body to restore the locked state of the lock.

[0040] In the preferred embodiment, the synchronization bar 8 is arranged inside the lock core 2, and slide bars 801 are provided on both sides of the synchronization bar 8. A slide groove is provided inside the lock core 2. The slide bar 801 is slidably connected to the slide groove of the lock core 2, and a tension spring 9 is provided between the end of the slide bar 801 and one end of the lock core 2; a docking port 301 is provided on the lock tongue 3, and the docking port 301 matches the end of the synchronization bar 8; the smart key 4 pushes the synchronization bar 8 to be inserted into the docking port 301.

[0041] After the smart key 4 is inserted into the lock core 2, the smart key 4 pushes the synchronization bar 8 to be inserted into the docking port 301, and the pin 12 comes out from the pin hole 101 inside the lock body 1. The smart key 4 can then rotate the lock core 2 and the lock tongue 3 at the same time. The lock tongue 3 moves the lock bolt to unlock the lock. After the smart key 4 is pulled out, the synchronization bar 8 retracts and returns to its original position under the action of the tension spring 9.

[0042] The slide bar 801 is arranged on both sides of the synchronization bar 8 and is slidably connected with the slide groove inside the lock core 2. The slide bar 801 provides stable guidance and support for the synchronization bar in the lock core to ensure its smooth movement.

[0043] The tension spring 9 is located between the end of the slide bar 801 and one end of the lock core 2 to provide a reset force for the synchronization bar. When the smart key 4 is not inserted or has been pulled out, the tension spring keeps the synchronization bar in the initial position.

[0044] The docking port 301 is provided on the lock tongue 3 and matches the shape of the end of the synchronization bar 8. The docking port 301 is used to receive the synchronization bar to realize the mechanical linkage between the lock tongue and the lock core.

[0045] When the smart key 4 is inserted into the lock core 2 and the electronic identity verification is performed, the specific structure at the front end of the smart key will push the synchronization bar 8. The synchronization bar slides smoothly along the slide groove, and its end is gradually inserted into the docking port 301 on the lock tongue 3.

[0046] At the same time, the temporary power provided by the smart key activates the motor 7, and the motor drives the pin 12 to extend from the pin hole 101 inside the lock body 1, thereby releasing the restriction on the rotation of the lock cylinder 2. At this time, the smart key can smoothly rotate the lock cylinder.

[0047] Since the synchronization bar 8 has been docked with the lock tongue 3, the rotation of the lock core 2 will be transmitted to the lock tongue 3 through the synchronization bar, so that the lock tongue rotates with the lock core. When the lock tongue rotates to a specific angle, it moves the lock bolt to complete the unlocking action.

[0048] After unlocking, the smart key 4 is pulled out from the lock cylinder. At this time, the synchronization bar 8 loses the pushing effect of the smart key, and retracts along the slide groove under the tension of the tension spring 9, and its end withdraws from the docking port 301 and separates from the lock tongue 3. The synchronization bar is reset to the initial position, waiting for the next unlocking operation.

[0049] The synchronization bar 8 achieves precise docking and separation with the lock tongue 3 through the cooperation of the slide bar 801 and the slide groove of the lock core 2, as well as the reset force provided by the tension spring 9. Under the push-up action of the smart key 4, the synchronization bar and the lock tongue are linked to ensure that the lock core can synchronously drive the lock tongue to unlock when it rotates. When the smart key is pulled out, the synchronization bar automatically resets under the action of the tension spring and returns to the standby state. The whole process achieves precise synchronization of the lock core and the lock tongue, ensuring the smooth and safe opening and closing of the lock.

[0050] In the preferred embodiment, the drive disk 10 is provided with an opening, and a limit column 701 is provided at the end of the motor 7. The limit column 701 is arranged on one side of the opening position of the drive disk 10, and the end surface of one side of the opening is against one side of the limit column 701, and a spring 11 is provided between the other side of the limit column 701 and the other side of the opening. After the driving pin 12 is retracted, the drive disk 10 can rotate the lock cylinder 2. When the smart key 4 is pulled out, the motor 7 is powered off, and the drive disk 10 returns to its position under the push of a spring 11. The pin 12 is inserted into the interior of the lock body 1, and the drive disk 10 is against the limit column 701 for limiting.

[0051] After the smart key 4 is authenticated, the motor 7 drives the disk 10 to rotate, and the pin 12 is retracted through the connecting rod 13, thereby releasing the restriction on the rotation of the lock cylinder 2. At this time, even if the smart key is not completely withdrawn, the lock cylinder 2 can be manually rotated to adjust the position of the lock tongue 3 or perform other necessary operations.

[0052] When the smart key 4 is completely pulled out, the motor 7 is powered off, and the driving disk 10 loses continuous power input. At this time, the spring 11 releases the stored energy and pushes the driving disk 10 back to the limit column 701. During the return process, the open end surface of the driving disk gradually approaches and finally abuts against the limit column 701 to achieve limit.

[0053] In the preferred embodiment, a groove is formed on one side of the lock core 2 at the key hole position, and a circuit board 5 is disposed inside the groove. The circuit board 5 is electrically connected to the motor 7 .

[0054] A slot is provided on one side of the keyhole of the lock core 2 to accommodate the circuit board 5. The design of the slot takes into full consideration the size of the circuit board, the fixing method, and the relative position with other components such as the motor to ensure that the circuit board is firmly installed and easy to maintain.

[0055] The circuit board 5 is installed in the slot body as the core part of the electronic control system. The circuit board integrates power management, signal processing, identity authentication, motor drive and other modules, and is responsible for receiving temporary power and identity information transmitted by the smart key 4, controlling the action of the motor 7, and processing other electronic functions related to the lock operation.

The power connection posts 502 pass through the lock core 2 and abut against the docking contacts 401 of the smart key 4. The smart key 4 is electrically connected to the circuit board 5 through the power connection posts 502. The end of the power connection post 502 is slidably connected to the circuit board 5. A limit ring is provided at the end of the power connection post 502. The limit ring abuts against the lock core 2 for the upper limit. A second spring 501 is provided between the end of the power connection post 502 and the circuit board 5. The end of the power connection post 502 abuts against the docking contacts 401 of the smart key 4 for data docking, and the circuit board 5 and the smart key 4 are docked.

[0057] In the preferred embodiment, an annular mounting groove 201 is further provided at the end of the lock core 2, a limiting groove 102 is provided inside the lock body 1 at a position corresponding to the mounting groove 201, and a limiting ring 6 is provided between the limiting groove 102 and the mounting groove 201. The outer diameter of the limiting ring 6 is larger than the outer diameter of the lock core 2 and smaller than the inner diameter of the limiting groove 102, and the inner diameter of the limiting ring 6 is larger than the outer diameter of the mounting groove 201 and smaller than the outer diameter of the lock core 2.
