In the present embodiment, as shown in fig. 7, the lock body 1 includes a first lock body 108 and a second lock body 109 that are engaged with each other front and back, and the first lock body 108 is made of plastic, and the second lock body 109 is made of metal; an antenna is arranged in the lock body 1 and is positioned in the first lock body 108, so that the antenna is not easily affected by the second metal lock body 109 to cause signal instability when receiving and transmitting signals; the second lock body 109 is made of metal, so that the rigidity of the lock body 1 can be improved, and the service life can be prolonged. The antenna is electrically connected with the circuit board. A waterproof gasket is further provided between the first lock body 108 and the second lock body 109, so that the waterproof performance can be further improved.

The mounting block 8 is disposed on the second lock body 109, and the display screen mechanism 5 and the password input mechanism 6 are disposed on the first lock body 108.

In this embodiment, the three drainage holes 103 are inclined from top to bottom to facilitate drainage.

The following presents a simplified summary of the invention in order to facilitate an understanding of the invention:

when the electronic logistics padlock is in a locking state, a user can press the awakening key 11 through the second waterproof cover 12 to enable the padlock to enter a normal working state, and then information such as electric quantity, use duration, unlocking/locking state and the like can be displayed on the display screen 51 to be checked by people; then the 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 13 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, the two magnets 9 correspondingly leave the sensing ranges of the two magnetic sensors 10, so that the unlocking state is displayed on the display screen 51, and the padlock enters the sleep mode. The unlocking of the padlock is completed through the steps. Certainly, if the logistics vehicle encounters rain and other conditions in the running process, the first waterproof cover 62, the second waterproof cover 12 and the transparent sheet 12 can prevent rain from entering the lock body 1 from the above three places, and damage to parts is avoided; and if rainwater enters from the first blind hole 101 and the second blind hole 102, the rainwater can be discharged from the first blind hole 101, the second blind hole 102 and the drain hole 103 in the mounting bin 81, and the rainwater can be prevented from accumulating.

When the electronic lock 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 two magnets 9 are correspondingly sensed by the two magnetic sensors 10, then, the locking state is displayed on the display screen 51, and the padlock enters a working mode. 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.
