Example (b):

A novel NFC passive padlock comprises a lock body 1 and a lock catch 2, wherein the lock catch 2 is of a U-shaped structure, and the lock catch 2 is connected with the lock body 1 in a sliding manner; the lock body 1 is internally provided with an ejection mechanism 3, a locking mechanism 4 and a control mechanism; one end of the lock catch 2 is connected with the pop-up mechanism 3 in a sliding way, and the other end is connected with the locking mechanism 4; control mechanism includes NFC wireless transmission module 5 and control module 6, and NFC wireless transmission module 5 includes electric energy module and signal module, and the electric energy module is connected with locking mechanism 4 and control module 6 electricity respectively, and signal module and 6 signal connection of control module, control module 6 and locking mechanism 4 electric connection.

The pop-up mechanism 3 includes a guide groove 31 and a first elastic member 32, and an end of the latch 2 connected to the pop-up mechanism 3 is connected to an inner bottom surface of the guide groove 31 by the first elastic member 32. Utilize the elastic action of first elastic component 32, make hasp 2 to toward popping out along guide way 31, reach the purpose of unblanking, simple structure practicality is strong.

A limiting block 21 is arranged at one end of the lock catch 2 connected with the pop-up mechanism 3, a limiting groove 33 is arranged in the pop-up mechanism 3, and the limiting groove 33 is arranged in parallel with the guide groove 31; the limiting block 21 is connected with the limiting groove 33 in a sliding mode. In order to prevent the lock catch 2 from being ejected excessively when ejected, the lock catch 2 is separated from the lock body 1. On one hand, a limiting groove 33 is arranged beside the guide groove 31, the limiting groove 33 is not opened, on the other hand, a limiting block 21 is arranged on the lock catch 2, and the limiting block 21 is connected with the limiting groove 33 in a sliding mode. So that the moving distance of the shackle 2 on the guide groove 31 is limited by the limiting groove 33, and the shackle 2 is ensured not to be ejected out and excessively separated from the lock body 1.

The locking mechanism 4 comprises a driving device 41, a driving rod 42 and a locking block 44, wherein the driving device 41 is connected with the driving rod 42, and the driving rod 42 is elastically connected with the locking block 44 through a second elastic piece 43; one end of the lock catch 2 connected with the locking mechanism 4 is provided with a clamping position 22, and the clamping position 22 is matched with the locking block 44. When locking, press the hasp 2 into the inside of lock body 1 with strength, because the latch segment 44 makes through second elastic component 43 elastic connection with actuating lever 42, when the hasp 2 is with the in-process of pressing into the inside of lock body 1, the latch segment 44 receives the external force from hasp 2 and to the elastic contraction of drive arrangement 41 direction, and elastic recovery afterwards makes the latch segment 44 block in the screens 22, accomplishes the locking process. At the same time, since the locking block 44 is tightly sunk into the detent 22 by the elastic force of the second elastic member 43, it is effectively ensured that the shackle 2 is firmly locked with the lock body 1.

The locking piece 44 is provided with an inclined surface on one side of the upper surface. When the shackle 2 is pressed into the lock body 1, the locking block 44 is guided along the inclined surface thereof to move toward the driving device 41 better, thereby improving the smoothness.

A rubber layer 7 is arranged at the connecting position of the lock body 1 and the lock catch 2. Considering that the lock body 1 contains electronic devices inside, in order to prevent moisture in the air from invading the inside of the lock body 1 along the gap between the lock body 1 and the shackle 2, the electronic devices are damaged, and the service life of the product is reduced. Set up rubber layer 7 at the lock body 1 with the junction of hasp 2, utilize the elastic deformation characteristic of rubber layer 7, the clearance between lock body 1 and the hasp 2 that significantly reduces prevents the moisture invasion.

The working principle of the embodiment is as follows:

Through the reverse wireless charging technology, the electric quantity is transmitted to the electric energy module by the mobile phone, and the electric energy module transmits the obtained electric quantity to the locking mechanism 4 and the control mechanism to provide a power source for the locking mechanism and the control mechanism. Subsequently, data is input to the signal module by using an APP (application) preinstalled on the mobile phone through an NFC (near field communication) data transmission technology, the signal module receives the data and then transmits the data to the control module 6, and then the control module 6 transmits an instruction to the locking mechanism 4. After the driving device 41 of the locking mechanism 4 receives the command, the driving rod 42 is retracted, so that the second elastic member 43, together with the locking block 44, moves toward the driving device 41, and the locking block 44 is disengaged from the detent 22, thereby releasing the locking of the shackle 2. After the latch 2 releases the locking of the locking block 44, the other end of the latch 2 is under the elastic action of the first elastic member 32, so that the latch 2 is sprung upward along the guide groove 31, and the unlocking process is completed. Waiting for two or three seconds, and after the lock catch 2 is popped up, the control module 6 controls the locking mechanism 4 to reset.

The whole unlocking process only needs to utilize a mobile phone, and is convenient and fast. Meanwhile, due to the fact that a reverse wireless charging technology is matched, the problem that the internal power of the electronic padlock is insufficient does not need to be worried about.
