The driving member 36 may be a motor or other power device, and the rotating portion 35 has a substantially cylindrical structure.

The power source 38 supplies power to the entire locking mechanism 3, and may be a battery, with the power source 38 being electrically connected to the fingerprint recognition controller 31. As shown in fig. 1 and fig. 10 to 11, the fingerprint identification controller 31 includes a fingerprint identification window 312, a circuit board 313, a display lamp 311, and a charging plug 314, the charging plug 314 provides an interface for charging the power supply 38, the fingerprint identification window 312, the display lamp 311, and the charging plug 314 are all electrically connected to the circuit board 313, the fingerprint identification window 312 and the display lamp 311 are both exposed out of the cover 6, the charging plug 314 is exposed out of the box main body 1, the fingerprint identification window 312 is used for collecting fingerprints, the circuit board 313 performs matching judgment according to the fingerprints collected by the fingerprint identification window 312 and determines whether to unlock, and two different colors displayed by the display lamp 311 prompt whether to match correctly.

Of course, it is initially necessary to store a target fingerprint, such as a home fingerprint, for the fingerprint recognition controller 31 through the mutual cooperation of the fingerprint recognition window 312, the circuit board 313 and the display lamp 311 to provide a base fingerprint for matching, and such target fingerprint collection will not be described in detail herein.

When the circuit board 313 identifies the fingerprint collected by the window 312 according to the fingerprint and determines that the fingerprint is not matched, the display lamp 311 displays red color to prompt that the fingerprint is input again and the lock is not unlocked; when the circuit board 313 determines that the fingerprint collected by the fingerprint identification window 312 matches the fingerprint collected by the fingerprint identification window, the display lamp 311 displays blue, and the unlocking operation is performed.

For better unlocking, referring to fig. 8-14, in the present embodiment, the cover 6 is provided with an installation groove 62 and an installation plate 7, the locking mechanism 3 is fixed in the installation groove 62, the installation groove 62 matches with the internal mechanisms of the locking mechanism 3, such as the power source 38, the fingerprint recognition controller 31, the driving member 36, the rotating portion 35, and the installation plate 7 fixes the installation groove 62 to cover the locking mechanism 3, so as to ensure the accuracy of the unlocking action of the locking mechanism 3. As shown in fig. 13 to 14, in order to provide the first elastic member 33 more stably, a blind hole 324 is opened at one end of the locking portion 32, one end of the first elastic member 33 abuts against the blind hole 324, and the other end of the first elastic member 33 abuts against a groove wall of the mounting groove 62.

In addition, the relevant mechanisms within the locking mechanism 3 are connected and operate as follows: the fingerprint recognition controller 31 is electrically connected to the driving member 36, the output end 361 of the driving member 36 is fixed to the rotating portion 35, the rotating portion 35 is provided with an eccentric rod 351, one end of the moving block 34 is provided with a sliding groove 343, and one end of the eccentric rod 351 is inserted into the sliding groove 343. The other end of the moving block 34 is provided with a touch portion 342, the moving block 34 is provided with an inclined portion 341, the locking portion 32 is provided with a passage 322, the moving block 34 passes through the passage 322, the sliding groove 343 and the touch portion 342 are located on the opposite side of the locking portion 32, the electronic switch 37 is electrically connected with the circuit board 313, the electronic switch 37 is provided with a button 371, and the button 371 is arranged opposite to the touch portion 342.

Referring to fig. 4 and fig. 8-14, after the circuit board 313 determines that the matching is successful according to the fingerprint collected by the fingerprint identification window 312, the circuit board 313 controls the driving element 36 to rotate, the driving element 36 drives the rotating portion 35 to rotate through the output end 361, the eccentric rod 351 of the rotating portion 35 moves in the sliding groove 343 to drive the moving block 34 to move along the channel 322, the inclined portion 341 of the moving block 34 presses the locking portion 32 to move, and drives the locking tongue 323 to move away from the latch 12, and the locking portion 32 compresses the first elastic element 33 at the same time, so that the locking tongue 323 and the latch 12 are not locked with each other, and the cover 6 can be opened by the moment.

An electronic switch 37 is installed to reset the structures of the driver 36, the moving block 34, the rotating portion 35, and the like. Specifically, during the moving process of the moving block 34 along the channel 322, the touching portion 342 of the moving block 34 acts on the button 371 to open the circuit, the electronic switch 37 opens the circuit in the fingerprint identification controller 31, at this time, the driving member 36 no longer drives the rotating portion 35 to rotate, the compressed first elastic member 33 returns to drive the locking portion 32 to move in the reverse direction, the locking portion 32 acts on the inclined portion 341 to drive the moving block 34 to move in the reverse direction, during the returning process, the touching portion 342 of the moving block 34 acts on the button 371 again to close the button 371, the electronic switch 37 connects the circuit in the fingerprint identification controller 31, but at this time, because the fingerprint judgment is not performed, the circuit board 313 does not control the driving member 36 to rotate again.

When the inclined portion 341 of the moving block 34 presses the locking portion 32 so that the latch tongue 323 and the latch 12 are no longer locked to each other, the cover 6 can be opened. However, since the time interval between the latch tongue 323 and the latch 12 is very short, in order to catch this chance, in this embodiment, the cover 6 is provided with the bouncing structure 8, and when the latch tongue 323 and the latch 12 are in the unlocked state, the bouncing structure 8 can act on the cover 6 to rotate, so as to drive the latch tongue 323 to rapidly move away from the latch 12 to unlock the lock.

Referring to fig. 4 and fig. 14-18, the pop-up structure 8 is disposed on one side of the cover 6, the pop-up structure 8 includes a second elastic member 83, a fixing plate 81 and a propping rod 82, the fixing plate 81 is provided with a through hole 84, and a side surface of the propping rod 82 is provided with an annular protrusion 85. The cover 6 is provided with an accommodating chamber 63, the fixing plate 81 is fixed to the cover 6, and the through hole 84 is disposed opposite to the accommodating chamber 63. The second elastic member 83 is disposed in the accommodating cavity 63, one end of the supporting rod 82 is fixed to the second elastic member 83 and is located in the accommodating cavity 63, and the other end of the supporting rod 82 passes through the through hole 84 and is exposed. The annular protrusion 85 may abut against the fixing plate 81, and the second elastic member 83 may be a spring or other elastic structure, in this embodiment, the second elastic member 83 is a spring.

When one side of the cover body 6 rotates relative to the box main body 1, so that the cover body 6 covers the key cavity 11, at the moment, the lock tongue 323 locks the fixture block 12, the free end of the abutting rod 82 abuts against the fixture block 12 and compresses the second elastic element 83; when the lock tongue 323 and the latch 12 are unlocked by the locking mechanism 3, the second elastic member 83 is rapidly restored, and the free end of the abutting rod 82 abuts against the latch 12, so that the second elastic member 83 acts on the cover 6 to drive the cover 6 to rotate in the opposite direction to make the lock tongue 323 away from the latch 12, and the cover 6 is opened, thereby taking out the key in the key cavity 11.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
