Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to an intelligent password U-lock. Background Technology

[0031] In an optional embodiment: the latch 7 includes a first latch 701, a second latch 702, a push spring 704, and a positioning post 705. The first latch 701 and the second latch 702 are both movably inserted into the moving groove 8. The first latch 701 and the second latch 702 are both provided with a fitting part 711. The fitting part 711 of the first latch 701 fits into the fitting part 711 of the second latch 702. The positioning post 705 is fixedly installed on the end of the first latch 701. The push spring 704 is sleeved on the positioning post 705. The second latch 702 has an avoidance groove 703. The upper end of the push spring 704 abuts against the inner wall of the avoidance groove 703.

[0032] It should be noted that by pushing the spring 704, the first latch 701 and the second latch 702 are reset, so that the lock automatically resets when the first latch 701 and the second latch 702 are used. When the first latch 701 and the second latch 702 are installed in the moving groove 8, the moving groove 8 can position the first latch 701 and the second latch 702 to prevent the first latch 701 and the second latch 702 from shifting.

[0033] In an optional embodiment: the first latch 701 is provided with a first actuating groove 706 and a second actuating groove 707, the second latch 702 is provided with a third actuating groove 708 and a fourth actuating groove 709, the mechanical lock cylinder 3 includes a lock shell 301, a lock cylinder 302 and a first actuating pin 303, the lock shell 301 is disposed inside the lock body 1, the lock cylinder 302 is movably installed inside the lock shell 301, the first actuating pin 303 is movably installed at the end of the lock cylinder 302, there are two sets of first actuating pins 303, one set of first actuating pins 303 is disposed in the first actuating groove 706 and the other set of first actuating pins 303 is disposed in the third actuating groove 708, a rotating seat 5 is fixedly installed on the conveying shaft of the motor 4, and two sets of second actuating pins 24 are fixedly connected to the side of the rotating seat 5, one set of second actuating pins 24 is disposed in the second actuating groove 707 and the other set of second actuating pins 24 is disposed in the fourth actuating groove 709.

[0034] It should be noted that, through the setting of the mechanical lock cylinder 3, when the key drives the lock cylinder 302 and the first actuating column 303 to rotate, the first actuating column 303 rotates and moves the first bolt 701 and the second bolt 702 through the first actuating groove 706 and the third actuating groove 708, thereby unlocking the lock.

[0035] In an optional embodiment: a retaining ring 710 is fixedly connected to both the first locking tongue 701 and the second locking tongue 702, a positioning groove 9 is provided inside the lock body 1, the moving groove 8 communicates with the positioning groove 9, and the retaining ring 710 contacts the inner wall of the positioning groove 9.

[0036] It should be noted that the retaining ring 710 serves to position the first locking bolt 701 and the second locking bolt 702.

[0037] In an optional embodiment, the sealing groove 12 is provided with an unlocking hole 13 corresponding to the mechanical lock cylinder 3 and a plugging hole 14 corresponding to the charging port 15.

[0038] It should be noted that the key can be inserted into the mechanical lock cylinder 3 through the unlocking hole 13 to drive the mechanical lock cylinder 3 to unlock the lock, and the battery 18 can be charged through the charging port 15.

[0039] In an optional embodiment: a sealing block 10 corresponding to the charging port 15 is fixedly connected to the side of the silicone sealing block 16. The sealing block 10 is inserted into the insertion hole 14, and the sealing block 10 contacts the inner wall of the insertion hole 14. One end of the sealing block 10 is inserted into the charging port 15.

[0040] It should be noted that by setting the sealing block 10, the sealing block 10 is inserted into the charging port 15, which improves the sealing effect of the charging port 15 and prevents water from entering the charging port 15, thus preventing the charging port 15 from getting damp and damaged.

[0041] In an optional embodiment: a mounting shell 19 is fixedly installed on the side of the lock body 1, a control circuit board 20 is fixedly installed inside the mounting shell 19, a fingerprint collector 21 is electrically connected to the control circuit board 20, and a touch button module 22 is fixedly installed on the side of the lock body 1.

[0042] It should be noted that users can unlock the lock by entering their fingerprint or numeric password through the fingerprint collector 21 and the touch button module 22.

[0043] In an optional embodiment: a battery 18 is fixedly installed inside the lock body 1, and the motor 4, charging port 15, battery 18, and touch button module 22 are all electrically connected to the control circuit board 20.

[0044] In an optional embodiment, the locking beam 2 has multiple sets of slots 17, and the ends of the first locking tongue 701 and the second locking tongue 702 are inserted into the two sets of slots 17.

[0045] In an optional embodiment: the lock body 1 has a wire hole 23 for mounting the wires of the battery 18 and the charging port 15, and the wire hole 23 is filled with adhesive.

[0046] It should be noted that by applying adhesive inside the wire hole 23, the wire hole 23 is sealed, which in turn seals the space between the lock body 1 and the mounting shell 19. This prevents water from entering the space of the mounting shell 19 and causing damage to the control circuit board 20 and the battery 18, thus improving the sealing effect of the control circuit board 20 and the battery 18. At the same time, it also serves to fix the wires of the control circuit board 20 and the battery 18.

[0047] In practical use, when the user enters the corresponding fingerprint or digital password, the control circuit board 20 starts the motor 4. The conveyor shaft of the motor 4 rotates, driving the rotating seat 5 to rotate. When the rotating seat 5 rotates, it drives the second actuating column 24 to rotate. When the second actuating column 24 rotates, it can push back the first locking tongue 701 and the second locking tongue 702 through the second actuating groove 707 and the fourth actuating groove 709, so that the first locking tongue 701 and the second locking tongue 702 move into the lock body 1, and the ends of the first locking tongue 701 and the second locking tongue 702 move out of the slot 17, thereby unlocking the lock.

[0048] The silicone sealing block 16 can seal the unlocking hole 13 and the insertion hole 14, preventing water from entering the mechanical lock cylinder 3 and the charging port 15 and causing damage to them. The sealing block 10 is inserted into the charging port 15, improving the sealing effect of the charging port 15. The waterproof silicone sleeve 11 can improve the sealing effect between the mounting groove 6 and the moving groove 8 where the motor 4 is installed. The glue in the wire hole 23 can seal the space between the lock body 1 and the mounting shell 19, preventing water from entering the space of the mounting shell 19 and causing damage to the control circuit board 20 and the battery 18, thus improving the sealing effect of the control circuit board 20 and the battery 18.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
