[0039] Please refer to Figures 1 to 12 , this embodiment provides a fingerprint password lock for a zipper bag, which includes a lock body 10 and a lock catch 20 that cooperates with the lock body 10. When the fingerprint password lock applied to the zipper bag is connected to the zipper bag, the lock body 10 is fixedly connected to the zipper 30 of the zipper bag, and the lock catch 20 is fixedly connected to the other pull tab of the zipper. Among them, the lock catch 20 or the lock body 10 is connected to the zipper it is connected to by a rotary structure mechanism.

[0040] The lock body 10 includes:

[0041] An upper cover assembly 11, in which a first installation cavity is provided;

[0042] A lower cover assembly 13, the lower cover assembly 13 is connected to the upper cover assembly 11, and a second installation cavity is provided in the lower cover assembly 13;

[0043] A fingerprint module 12, the fingerprint module 12 is arranged in the first installation cavity;

[0044] A lock hook assembly 14, the lock hook assembly 14 is arranged in the second installation cavity; and

[0045] A shape memory wire (not shown in the figure), the shape memory wire is electrically connected to the fingerprint module 14, and the middle part is wound around the lock hook assembly 14. When the fingerprint module 14 receives fingerprint information and the verification is passed, it controls the shape memory wire to be energized, and the shape memory wire deforms to drive the lock hook assembly 14 to perform telescopic movement to achieve unlocking.

[0046] In this embodiment, a shape memory wire controlled by power on and off is used as the power unit of the lock hook assembly 14. Compared with the existing motor drive method, the shape memory wire is smaller in volume and occupies less space in the lock body. Therefore, it is also beneficial to the miniaturized design of the lock body 10, so that the fingerprint password lock is more compact and beautiful when applied to the zipper bag.

[0047] Please refer to again Figures 9 to 11, the hook assembly 14 includes: a hook 141, a first elastic member 142, and a second elastic member 142. One end of the first elastic member 142 elastically acts on the rear end portion of the hook 141 horizontally, and the second elastic member 142 is disposed at the front end portion of the hook 141 and acts on the front end portion of the hook 141 vertically. Specifically, a guiding column 1411 is provided at the rear end portion of the hook 141, and the first elastic member 142 is sleeved on the guiding column 1411. When the conductive circuit of the shape memory wire is disconnected, the second elastic member 142 drives the hook 141 to extend, and at this time, the hook 141 and the lock catch 20 are in a locked state. The first elastic member 142 is a spring, and at least two guiding columns 1411 are provided, and corresponding elastic members are also provided in corresponding numbers. The elastic recovery mechanism composed of multiple springs and the guiding columns 1411 can increase the smoothness and stability of the reciprocating movement of the lock catch 141, and prevent the hook 141 from shifting and jamming during the movement.

[0048] Among them, the lower cover assembly 13 includes: a bottom cover 131 having a cavity, a base 132 disposed in the cavity, and a connecting frame 133 connected to the periphery of the bottom cover 132. An installation groove 1321 is provided at the front end of the base 132, the hook assembly 14 is disposed in the installation groove 1321, and a limiting portion 1322 is further provided in the installation groove 1321. The hook 141 can reciprocate horizontally along the limiting portion 1322. In this embodiment, both the bottom cover 131 and the base 132 are rectangular plate-like structures. The base 132 is fixedly assembled in the cavity of the lower cover 131, and the base 132 is used to provide a reciprocating horizontal movement space for the hook assembly 14. The limiting portion 1322 is a limiting plate portion protruding vertically upward from the bottom of the installation groove 1321. A movement limiting space for the hook 141 is formed between the two limiting plate portions, and corresponding guiding surfaces are provided on the hook 141 corresponding to the limiting plate portions. The lock catch 141 is controlled by the shape memory wire. When the shape memory wire is energized and conducts electricity, it undergoes a contraction deformation, and the hook 141 retracts and moves, so that the hook 141 withdraws from the lock hole 231 of the lock catch 20 to achieve unlocking.

[0049] Such as Figure 10 And Figure 11As shown, a fixing part 1323 is further provided at the bottom of the installation groove 1321. The second elastic member 143 is a U-shaped spring. The middle part of the U-shaped spring is fixed to the fixing part 1323, and the elastic ends of the U-shaped spring are located below the front end of the locking hook 141 to provide a vertical elastic force. Specifically, the two ends of the U-shaped spring are upturned compared with the middle part, the middle part is clamped to the fixing part 1323, and the two ends are upturned. The upturned ends of the U-shaped spring can be located directly below the locking hook 141 or on both sides below the locking hook 141 at the same time. When the lock catch 20 is locked to the locking hook 141, the two end parts of the U-shaped spring are pressed downward by the lock catch 20 to be in a compressed state. When the locking hook 141 is driven to retreat by the controlled shape memory wire, the lock catch 20 is disengaged from the locking hook 141, and the lock catch 20 pops upward under the action of the U-shaped spring, so that the lock catch 20 is disengaged from the lock body 10.

[0050] Please refer to again Figure 7 、 Figure 8 and Figure 9 As shown in, at least two roller columns 1320 are further provided on the base 132. Rollers 16 are provided on the roller columns 1320, and the shape memory wire is wound around the rollers 16. Winding the shape memory wire around the rollers 16 can, on the one hand, reduce the resistance when the shape memory wire expands and contracts, and on the other hand, improve the power-on response speed of the shape memory wire. Specifically, in this embodiment, there are four rollers 16, and the four rollers 16 are distributed in a substantially rectangular shape. Two of the rollers 16 at the end far from the locking hook 141 are vertically connected to the base 132, and the two rollers 16 on the side close to the locking hook 141 are horizontally connected to the base 132, and the two rollers 16 on the side close to the locking hook 141 are respectively located on both sides of the locking hook 141. The middle part of the shape memory wire passing around the two rollers 16 abuts against the locking hook 141.

[0051] Furthermore, in order to simplify the assembly of the shape memory wire, the rollers 16 are arranged around the outer side wall of the base 132.

[0052] As Figure 8 shown, an installation cavity is further provided in the middle of the base 132, and a storage battery 15 is further provided in the installation cavity. The storage battery 15 is electrically connected to the fingerprint module 12.

[0053] Please refer to again Figure 6 As shown in, the connecting frame 133 includes: a frame 1331 and a plurality of insertion feet 1332 vertically connected to the frame 1331. The frame 1331 abuts against the top surface edge of the bottom cover 131, and the plurality of insertion feet 1332 surround the outer side wall of the bottom cover 131. And the length of the insertion feet 1332 is greater than the height of the bottom cover 131, so that the end parts of the insertion feet 1332 protrude from the lock body 10. When the lock body 10 is fixedly connected to the zipper bag, the insertion feet 1332 penetrate through the zipper bag.

[0054] In other embodiments, the connecting frame 133 may not be provided, and instead, the lock body 10 may be directly fixedly connected to the zipper bag by screws or rivets passing through the bottom cover 131 of the lock body.

[0055] The fingerprint module 12 includes a control circuit board 113, on which a fingerprint recognition chip and a control element for controlling the on / off of the electrical circuit of the memory metal wire are provided.

The fingerprint module 12 is disposed in the cavity, and the upper cover 111 is connected to the lower cover assembly 13. The upper cover assembly 11 and the lower cover assembly 13 are fixedly connected by screwing with bolts or screws. A fingerprint window 1142 is also provided on the decorative plate 114, and the fingerprint window 115 is disposed at this fingerprint window 1142. A through hole 1141 communicating with the mounting groove 1121 is also provided on the decorative plate 14, and the lock catch 20 extends into the lock hook assembly 14 through this through hole 1141 to realize the locking of the two.

[0057] Please refer to again Figure 1 and Figure 4 , the fingerprint password lock for the zipper bag further includes a lock catch 20. A lock hole is provided on the upper cover assembly 11, and the lock catch is inserted into the lock hole. Specifically, the lock catch 20 includes: a lock catch body 21, a connection card slot 22 provided on the lock catch body 21, and a lock tongue 23.
