If not match, the motor 34 does not rotate, if match, the circuit board 310 controls the motor 34 to rotate, drives the first connecting rod 35 to rotate, the eccentric column 351 drives the locking rod 37 to rotate, the compression torsion spring 36, the bending part 371 (fig. 11) is far away from the locking position 121, the elastic part 4 recovers, the first locking rod 12 is driven to move outwards, the second locking rod 11 is driven to be far away from the second locking hole 219, the opening end of the second locking hole 219 is left, and unlocking is achieved. In addition, according to the design of the circuit board 310, the circuit board 310 controls the motor 34 to rotate for several seconds, so as to rotate the eccentric cylinder 351 by a small angle, such as less than 90 °, but it is required to ensure that the locking position 121 can be separated from the bent portion 371 (fig. 11).

In order to mount and fix the circuit board 310, the motor 34, the first link 35, the power source 32, the key cylinder 33, the second link 39, the locking lever 37, and the rotating lever 38, referring to fig. 5, the padlock 100 further includes a plurality of mounting plates 311, wherein one mounting plate 311 is disposed on the circuit board 310, a plurality of mounting positions 3111 are disposed on the mounting plate 311, and the mounting positions 3111 are used for fastening and fixing the circuit board 310, the motor 34, the first link 35, the power source 32, the key cylinder 33, the second link 39, the locking lever 37, and the rotating lever 38.

Any one or two of the unlocking modes can be set. In the present embodiment, the padlock 100 employs two unlocking methods. However, in the second unlocking method, when the eccentric cylinder 351 drives the locking lever 37 to rotate, since the locking lever 37 and the rotating lever 38 are fixed, the rotating lever 38 also rotates, but the rotating lever 38 is engaged with one end of the second link 39, and the other end of the second link 39 is fixed to the output shaft of the key cylinder 33, at this time, the rotating lever 38 is difficult to rotate relative to the second link 39 and the key cylinder 33, which results in that the eccentric cylinder 351 cannot drive the locking lever 37 to rotate, that is, the second unlocking method fails.

In order to solve the problem, the mutual influence generated when the two unlocking modes are unlocked is avoided. Referring to fig. 11-12, the locking lever 37 is fixed to the rotating lever 38 to form a lever structure, the other end of the second link 39 is provided with an engaging hole 392, a groove 3921 is provided on the inner wall of the engaging hole 392, and a protrusion 381 is provided at a position of the rotating lever 38 opposite to the groove 3921. Because the first unlocking mode is that the rotating rod 38 is driven to rotate by the rotation of the second connecting rod 39 driven by the lock cylinder 33, when the second connecting rod 39 is driven to rotate by the lock cylinder 33, the protruding portion 381 abuts against the groove 3921, and therefore the rotating rod 38 is driven to rotate by the second connecting rod 39. Because of the second mode of unblanking is that to rotate drive dwang 38 through eccentric post 351 drive locking lever 37 and rotate, when eccentric post 351 drive locking lever 37 rotated, at this moment, protruding portion 381 can rotate certain angle relatively recess 3921, makes locking lever 37 drive dwang 38 rotate, and when protruding portion 381 rotated in recess 3921, second connecting rod 39 can not block the rotation of dwang 38. Through the arrangement of the groove 3921 and the protruding portion 381, mutual influence generated when the two unlocking modes are unlocked is solved, and independence of the two unlocking modes is ensured.

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.
