In this embodiment, be equipped with an installation piece in the top of circuit board and battery, unblock lock mechanism 3 is installed in an installation storehouse of this installation piece to can prevent that the rainwater direct contact from to spare parts such as circuit board and battery, avoid damage such as circuit board and battery. Specifically, the first magnetic inductor 7 and the second magnetic inductor 8 are located outside the mounting block.

The following describes the principle of use of the utility model in order to understand the utility model:

when the padlock is in a locking state, a user can send out an instruction to unlock through inputting a password, mobile phone control or remote control; after the instruction is sent, the circuit board sends an instruction to the motor 33 to enable the motor 33 to rotate, the eccentric block 34 is synchronously driven to rotate, the eccentric cam 341 drives the lock tongue 32 to move towards the lock tongue spring 31, and the lock tongue spring 31 is compressed; when the sensing block 343 contacts the sensing end of the travel switch 35, the motor 33 stops, and at this time, the locking tongue 32 disengages from the locking groove 203, so that the locking hook 2 moves upward under the stretching force of the locking hook spring 4, and unlocking is realized; after the lock hook 2 moves upwards to realize unlocking, the motor 33 synchronously resets to separate the eccentric block 34 from the travel switch 35, but the lock tongue 32 cannot reset because the lock tongue 32 is tightly pressed by the lock hook 2; meanwhile, when the latch hook 2 moves, the first magnet 5 and the second magnet 6 correspondingly leave the sensing ranges of the first magnetic inductor 7 and the second magnetic inductor 8, so that the display screen 10 is in an unlocked state, and the mobile phone and other terminal devices are correspondingly in an unlocked state. The unlocking of the padlock is completed through the steps.

When the padlock is in an unlocking state, a user aligns the short hook arm 202 of the lock hook 2 with the second blind hole 102 and pushes down, so that the short hook arm 202 falls into the second blind hole 102, the long hook arm 201 is driven to move downwards synchronously, the lock hook spring 4 is compressed until the locking groove 203 is aligned with the lock tongue 32, then the lock tongue 32 is clamped into the locking groove 203 due to the stretching force of the lock tongue spring 31 to realize locking, at the moment, the first magnet 5 and the second magnet 6 are just sensed by the first magnetic inductor 7 and the second magnetic inductor 8 correspondingly, then, the display screen 10 displays a locking state, and the terminal equipment such as a mobile phone also displays a locking state. When the latch hook 2 is damaged, the circuit board sends an alarm prompt to terminal equipment such as a mobile phone. The padlock is locked through the steps.

The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
