All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.

As shown in fig. 1, the electronic lock with two lock holes and double opening comprises a lock body 1, a mechanical unlocking part 2, an electrically driven unlocking part 3, a lock bolt assembly 4 and a lock beam 5.

A mechanical unlocking member 2, an electrically driven unlocking member 3 and a bolt assembly 4 are arranged in the lock body 1. The shackle 5 is provided with two locking bars 51 which are parallel and connected to each other. Two lock holes 11 are arranged on the lock body 1; the two lock rods 51 of the lock beam 5 are matched with the two lock holes 11; at least one pair of locking grooves 511 are arranged on the two locking bars 51 of the lock beam 5; a pair of locking slots 511 are adapted to the plug assembly 4. In a state where the two lock bars 51 of the lock beam 5 are inserted into the two lock holes 11, both ends of the latch assembly 4 are inserted into the pair of lock grooves 511 one by one, thereby achieving locking. In a locking state, the two ends of the lock bolt assembly 4 can be driven to move by the electrically driven unlocking part 3 or the mechanically unlocked part 2, so that the two ends of the lock bolt assembly 4 are respectively separated from the pair of lock grooves 511 to realize unlocking.

In some embodiments, both ends of the latch assembly 4 are capable of simultaneous telescoping. In the latched state, the latch assembly 4 is simultaneously retracted and separated from the pair of latch grooves 511.

In some embodiments, a latch hole 12 is disposed between the two latch holes 11. The two lock holes 11 are respectively communicated with the bolt holes 12. The plug assembly 4 is installed in the plug bore 12. One side of the lock body 1 is provided with a lock bolt inlet. The plug inlet communicates with the plug bore 12. The bolt assembly 4 is installed into the bolt bore from the bolt entrance.

In the above embodiment, during the unlocking process, the electrically driven unlocking part 3 may control the two ends of the latch assembly 4 to extend or retract according to the received unlocking instruction, or the mechanical unlocking part 2 may control the two ends of the latch assembly 4 to extend or retract under the driving of the key; after the two ends of the lock bolt assembly 4 are stretched, the lock bolt assembly is separated from the lock groove 511 on the lock beam 5, and unlocking is realized. The bolt assembly 4 is telescopically controlled through the electrically driven unlocking part 3 or the mechanically unlocked part 2, so that the electronic lock has two unlocking modes, and the electronic lock cannot be unlocked due to circuit faults.

As shown in fig. 2 and 3, in some embodiments, the latch assembly 4 includes a first latch 41, a second latch 42, a first spring 43, and a second spring 44.

The first latch 41 is engaged with the second latch 42 to form a cylinder. The first latch 41 has a first notch 411 and a second notch 412 on its side wall. The second latch 42 has a third notch 421 and a fourth notch 422 on its side wall. The first notch 411 and the third notch 421 are staggered to form a first shrink driving slot, and the second notch 412 and the fourth notch 422 are staggered to form a second shrink driving slot. A first spring position 45 (see fig. 4) and a second spring position 46 (see fig. 3) are arranged between the first locking bolt 41 and the second locking bolt 42. The first spring 43 is mounted on the first spring position 45; the second spring 44 is mounted on the second spring seat 46. The first spring 43 has one end abutting the first latch 41 and the other end abutting the second latch 42. The second spring 44 has one end abutting the first latch 41 and the other end abutting the second latch 42. The first spring 43 and the second spring 44 are used to generate a force that resists the mutual contraction of the first latch 41 and the second latch 42.

In the above embodiment, in a natural state, the first latch 41 and the second latch 42 are extended by the biasing force of the first spring 43 and the second spring 44, and the first retraction driving groove and the second retraction driving groove are formed by the notches of the first latch 41 and the second latch 42 which are displaced from each other; thus, when the electronic lock is in a locked state, after the side walls of the first retractable driving groove or the second retractable driving groove are subjected to external torsion, the first latch 41 and the second latch 42 are retracted with each other, the ends of the first latch 41 and the second latch 42 are separated from the locking groove 511 on the lock beam 5, and unlocking is achieved.

As shown in fig. 4, in some embodiments, the electrically driven unlocking means 3 comprises a motor 31. The motor 31 is provided with a first dial 311. The mechanical unlocking part 2 comprises a lock cylinder 21; the key cylinder 21 is provided with a second dial 211. The motor 31 is used for driving the first shifting block 311 to rotate so as to generate torsion on the first gap 411 and the third gap 421, and the lock cylinder 21 is used for driving the second shifting block 211 to rotate so as to generate torsion on the second gap 412 and the fourth gap 422, so that the first lock bolt 41 and the second lock bolt 42 are mutually contracted.

In some embodiments, the electric drive further comprises a battery and a control board. The control board is electrically connected to the motor 31. The control panel is used for receiving an unlocking instruction and controlling the rotating shaft of the motor 31 to rotate according to the unlocking instruction. The battery is used to power the control board and the motor 31.

In the above embodiment, the first shifting block 311 and the second shifting block 211 can rotate in the first retraction driving groove and the second retraction driving groove, respectively, to generate torsion to the notches of the first latch 41 and the second latch 42, thereby controlling the first latch 41 and the second latch 42 to retract. The first shifting block 311 and the second shifting block 211 are respectively controlled by the motor 31 and the lock cylinder 21 to realize the electronic unlocking and the mechanical unlocking of the electronic lock.

In some embodiments, the control board is electrically connected to the fingerprint identification module or the bluetooth module. The fingerprint identification module is used for identifying fingerprint information and sending an unlocking instruction to the control panel according to the fingerprint information; the Bluetooth module is used for receiving the wireless secret key and transmitting the wireless secret key to the control panel, and the control panel generates an unlocking instruction according to the wireless secret key. The generation of the unlocking instruction according to the wireless key is the prior art, and is not described herein again.

In some embodiments, the shackle 5 is a U-shaped shackle, i.e. the shackle 5 is U-shaped.

As shown in fig. 2 to 4, in some embodiments, both ends of the latch assembly 4 are provided with a packing 10 for waterproofing.

Specifically, the ends of the first latch 41 and the second latch 42 are provided with the packing 10, respectively. The sealing ring 10 is attached to the inner side wall of the bolt hole 12, so that the bolt hole 12 forms a closed space to prevent rainwater or dust from entering the lock body 1 from the opening of the bolt hole 12 and corroding the components inside the lock body 1.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
