AI Technical Summary
The motors in existing fingerprint padlocks are prone to jamming because the motor needs to reciprocate in two directions, which increases friction between the motor parts.
A reset component is used to help the lock cylinder reset, and the motor only needs to be driven in one direction. The friction between motor parts is reduced by the torsion spring and limit block structure, which prevents the motor from jamming.
This reduces friction between motor parts, prevents motor jamming, and improves the lifespan of the motor and the safety performance of the padlock.

[0026] like Figures 1 to 7 As shown, this is an embodiment of the present invention: a fingerprint padlock, including a lock body and a lock beam 1. The lock beam 1 has a fixed end 2 at one end and a movable end 3 at the other end. The fixed end 2 is pivotally connected to the lock body. The lock body has a lock hole 4 adapted to the movable end 3. The lock body has a lock cylinder 5 inside for locking or unlocking the movable end 3. The lock body includes a shell 6 and a first cover plate 7 and a second cover plate 8 fastened to both sides of the shell 6. The lock body also includes an inner liner 9 disposed inside the shell 6. The lock body is also equipped with a motor 10 and a fingerprint module 11 that are electrically connected to each other. The motor 10 drives a drive component 12 to rotate and move the lock cylinder 5 to the unlocking movable end 3. The lock cylinder 5 is also connected to a reset component that drives the lock cylinder 5 to the locking movable end 3.
[0027] The beneficial effects of this design are as follows: the motor-driven drive unit moves the lock cylinder to the movable end of the unlocking lock beam, and the reset component helps the lock cylinder reset to the movable end of the locking lock beam. With the help of the reset component, the motor does not need to perform reciprocating drive in two directions. The drive unit only needs to rotate in one direction to unlock the lock cylinder. The motor can drive 360° rotation, which reduces friction between motor parts, avoids motor jamming, and thus improves the service life of the motor.
[0028] Further configuration: the lock cylinder 5 is rotatably mounted in the lock body; the reset assembly includes a torsion spring 13; a rotating shaft 14 protrudes from the end face of the lock cylinder 5; the rotating shaft 14 has a transverse groove 15; the inner side of the outer shell 6 has a rotating cavity 16 for mounting the torsion spring 13 and the lock cylinder 5; the torsion spring 13 is sleeved on the outer side of the rotating shaft 14, with one end extending into the transverse groove 15 to form a snap-fit, and the other end abutting against the inner wall of the rotating cavity 16.

[0030] Further arrangement, the side wall of the lock cylinder 5 is provided with a locking block 17 and a driven block 18, the movable end 3 is recessed with a lock slot 19 matched with the locking block 17, and the side wall of the driving part 12 is provided with a driving block 20, when the motor 10 drives the rotating driving part 12, the driving part 12 abuts the driven block 18 through the driving block 20 and drives the lock cylinder 5 to rotate, and the fingerprint module 11 is also electrically connected with a switch 21 for blocking or allowing the driving block 20.
[0031] The beneficial effects of such an arrangement are as follows: when the driving part rotates to a certain position, the driving block on the side wall contacts the driven block, the driving part continues to rotate to drive the lock cylinder to rotate in the opposite direction, until the driving part rotates to the position where the driving block is separated from the driven block, and the lock cylinder completes the unlocking action, the switch is used to limit the driving block, and the switch is opened to allow the driving block to rotate when the fingerprint module is triggered, which can avoid the padlock from being directly unlocked by knocking or vibration, and improves the safety performance of the padlock.
[0032] Further arrangement, the inner liner 9 is provided with a limiting block 22 and a limiting inclined slot 23 corresponding to the position of the lock cylinder 5, when the lock cylinder 5 locks the movable end 3, the locking block 17 is clamped with the lock slot 19, and the side wall of the locking block 17 abuts the limiting block 22, when the lock cylinder 5 unlocks the movable end 3, the locking block 17 is separated from the lock slot 19, and the side wall of the driven block 18 abuts the limiting inclined slot 23.
[0033] The beneficial effects of such an arrangement are as follows: the limiting block and the limiting inclined slot respectively limit the lock cylinder to rotate to the locked position and the unlocked position, prevent the lock cylinder from being stuck due to over-rotation, and also ensure the stability of the lock cylinder in the locked position, which cannot be directly unlocked by external knocking or vibration.
[0034] Further arrangement, the inner liner 9 is provided with a mounting hole 24 corresponding to the position of the lock hole 4, and a spring 25 is arranged in the mounting hole 24, when the movable end 3 is locked in the lock hole 4, the movable end 3 compresses the spring 25.
[0035] The beneficial effects of such an arrangement are as follows: when the movable end is unlocked by the lock cylinder, the spring rebounds to drive the movable end to quickly pop out of the lock hole, achieving the effect of quick unlocking, and avoiding unlocking failure.
[0036] Further arrangement, the mounting hole 24 is further provided with a top rod 26, the top rod 26 is provided with a counterbore 27 for spring 25 to extend into, when the movable end 3 is locked in the lock hole 4, the movable end 3 is locked by abutting the top rod 26 and compressing the spring 25.
[0037] The beneficial effects of such arrangement are as follows, the movable end compresses the spring by contacting the top rod, increases the contact area, ensures the normal compression of the spring when the movable end is locked, the counterbore of the top rod is provided for the spring to extend into, prevents the torsion failure of the spring.
[0038] Further arrangement, the outer wall of the top rod 26 is provided with a ring table 28, the diameter of the one end of the top rod 26 close to the counterbore 27 is greater than the other end, the edge position of the inner lining 9 corresponding to the mounting hole 24 is detachably provided with a stop rod 29 for blocking the ring table 28.
[0039] The beneficial effects of such arrangement are as follows, the stop rod is used for the ring table to abut, limits the position of the top rod, prevents the top rod from being ejected out of the mounting hole by the spring, and the top rod of such structure can also normally compress the spring, the stop rod is detachable, facilitates the replacement or maintenance of parts.
[0040] Further arrangement, the lock core 5 is further connected with a TSA key lock 30 for driving the lock core 5 to move.
[0041] The beneficial effects of such arrangement are as follows, the lock core can also be driven to rotate by the TSA key lock, and then the padlock is unlocked, the TSA key lock is TSA customs lock, which refers to the safety detection of the U.S. customs on the transit luggage and goods, and the universal TSA special key of international customs is used to ensure the safety of goods in the transportation process, and various unlocking modes are used to make the use more convenient.
[0042] The above only discloses the preferred embodiment of the utility model, of course, cannot be used to limit the scope of the utility model, therefore, the equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
