TECHNICAL FIELD
[0001] The utility model relates to the field of intelligent security, especially a double opening padlock based on NFC function. BACKGROUND
[0002] Locks, as important tools to protect goods and prevent unauthorized access, have been playing an indispensable role in people's daily life since ancient times. Traditional lock design mostly adopts an open structure, that is, the lock body and the lock tongue part are directly exposed outside, and the opening or locking function is realized by inserting and rotating the physical key. Although this design is classic and meets the basic security needs to some extent, its limitations have become increasingly apparent with the progress of science and technology and the improvement of social security needs. Open locks are not only vulnerable to external damage, but also bring a lot of trouble in carrying, storing and replacing keys when managing a large number of locks.
[0003] In certain fields, such as substations and other critical infrastructure, the safety and convenience of locks are more strictly required. However, most of the lock opening devices currently used in substations still remain at the stage of traditional mechanical locks, and these locks have obvious deficiencies in convenience and applicability. On the one hand, due to the complex environment and wide distribution of substations, traditional mechanical locks require workers to carry a large number of keys, which not only makes the operation cumbersome, but also increases the risk of key loss or theft. On the other hand, traditional locks lack remote monitoring and management functions, and once an emergency situation requires quick unlocking, the inability to respond in time will affect work efficiency and safety. In addition, with the development trend of smart grids and unattended substations, the demand for intelligent and networked locks is increasingly urgent, and existing devices are obviously difficult to meet these emerging needs.
[0004] In summary, the main drawback of current locks is that they rely too much on the mechanical operation mode of physical keys, which not only limits the flexibility and efficiency of unlocking, but also highlights serious safety hazards in the context of the rapid development of smart substations. Smart substations emphasize remote monitoring, automated control and efficient operation and maintenance, while traditional mechanical locks will directly lead to the inability to unlock in time once they encounter key loss or damage, thereby affecting the normal inspection, maintenance and fault handling of equipment, and in severe cases, it may even endanger the safe and stable operation of the power grid. Therefore, it is particularly important to develop a new type of lock that can overcome the limitations of existing locks and integrate safety, convenience and intelligence. SUMMARY

Before unlocking, you only need to pinch the protective plate 20 and then rotate it.
[0029] When the user uses, if the physical key 4 is selected to open the lock, the correct key 4 needs to be inserted into the lock cylinder 3 and rotated, the rotation of the lock cylinder 3 drives the first gear 41 connected to the top to rotate, and then drives the first rack 6 meshed with it to slide in the first fixed frame 5, the first rack 6 pushes the clamping plate 10 to slide along the guide frame 12, compresses the return spring 13, and makes the clamping plate 10 gradually separate from the lock beam 2. Once the clamping plate 10 completely separates from the lock beam 2, the rebound force of the unlocking spring 18 will pop out the lock beam 2, and the user can turn the lock beam 2 to open the lock. After unlocking, the lock cylinder 3 rotates back, the return spring 13 rebounds to push the clamping plate 10 and the first rack 6 to reset. If the smart unlocking is selected, the user can pass the NFC card or the NFC signal recorded in the mobile phone close to the NFC inductor 111 of the lock body 1, and the inductor sends a signal to the processor 11 after successful identification, and the processor 11 controls the motor 71 to start, and the motor 71 drives the second gear 72 to rotate, and then drives the second rack 9 to slide on the second fixed frame 8, and pushes the clamping plate 10 to complete the separation from the lock beam 2, and the unlocking spring 18 pops out the lock beam 2 to achieve unlocking. In addition, the processor 11 can also receive matching unlocking instructions sent through other wireless ways, such as Bluetooth, Wi-Fi, etc., so as to control the motor 71 to start and complete the unlocking. When relocking, the user passes the lock beam 2 through the locked object and presses downward, the lock beam 2 extrudes the clamping plate 10 and the unlocking spring 18, the clamping plate 10 slides and compresses the return spring 13, and when the lock beam 2 is repositioned with the clamping plate 10, the return spring 13 rebounds to push the clamping plate 10 to insert into the lock beam 2, and the locking is completed. The battery 14 supplies power for the smart components, can be replaced through the groove and baffle 15 at the bottom of the lock body 1, and the solar panel 17 installed on the surface of the lock body 1 can charge the battery 14 when the light is sufficient. The reflective sticker 19 on the surface of the lock body 1 can display the position of the lock body 1 at night or in poor light, and the protection plate 20 at the bottom of the lock body 1 can be magnetically attracted to the lock body 1, covering the lock hole and the battery 14, and only needs to be rotated before unlocking.
