The electromechanical integrated lock core 300 is provided with a key hole 312 for inserting a computer key, the electromechanical integrated lock core 300 has an unlocking position and a locking position, and the computer key can reciprocate in the electromechanical integrated lock core 300 in the unlocking position and the locking position. When the computer key moves to the unlocking position, the end of the locking part 200 can be freely inserted into or separated from the lock hole 110. After the tail end of the locking part 200 is inserted into the lock hole 110, the computer key is moved to the locking position, and the lock can be locked in the lock hole 110, so that the locking part 200 and the lock hole 110 cannot be separated, and locking is realized.

The mechatronic lock cylinder 300 and the passive electronic lock according to the embodiment of the invention are described in detail below in a specific embodiment with reference to fig. 1 to 6. It is to be understood that the following description is only exemplary, and not a specific limitation of the invention.

Referring to fig. 1, in the present embodiment, the electronic locking mechanism 320 includes a locking motor 321, a locking tongue 323, a motor rotating block 322, and a contact 327. The motor rotating block 322 is disposed on an output shaft of the locking motor 321, and can be driven by the locking motor 321 to rotate. The lock tongue 323 is slidably disposed on the lock cylinder 310, one end of the lock tongue 323 is provided with a spherical surface, the mechanical locking mechanism 330 is correspondingly provided with a first lock groove, the motor rotating block 322 can rotate to a fixed position under the driving of the locking motor 321, and the end with the spherical surface of the lock tongue 323 is pushed into the first lock groove to limit the movement of the lock cylinder 310. The contact 327 is electrically connected to the locking motor 321 and the position sensor 410 of the key cylinder detection mechanism 400, respectively, and when a computer key is inserted into the key hole 312, the computer key controls the locking motor 321 to move and receives a signal of the position sensor 410 through the contact 327. In this embodiment, referring to fig. 6, a semi-cylindrical boss with a half cut off along a diameter is disposed on the motor rotation block 322, the semi-cylindrical boss starts a cam action, and when a curved surface of the semi-cylindrical boss faces the lock tongue 323, the lock tongue 323 is obstructed by the curved surface of the semi-cylindrical boss when moving into the lock cylinder 310, and cannot be completely retracted into the lock cylinder 310 and separated from the first lock groove. When the plane of the semi-cylindrical boss faces the lock tongue 323, the lock tongue 323 has a certain movement space between the first lock groove and the motor rotating block 322, and at this time, the lock core 310 is driven to move by rotating the computer key, so that the lock tongue 323 can compress the lock tongue pressure spring 324 under the pressure effect and retract into the lock core 310 to be separated from the first lock groove, and the lock core 310 can move to the unlocking position.

Referring to fig. 5, in the present embodiment, the locking motor 321 is a dc motor, a limit block 326 for stopping the motor rotation block 322 is disposed on the locking motor 321, and a torsion spring 325 is disposed between the motor rotation block 322 and the locking motor 321. When the motor rotating block 322 is driven by the locking motor 321 to rotate instantaneously during locking, the limiting block 326 can enable the motor rotating block 322 to stop at the position where the curved surface faces the bolt 323 so as to limit the movement space of the bolt 323, the locking motor 321 stops rotating under the action of the torsion spring 325, and the torsion spring 325 accumulates elastic potential energy. When the lock is unlocked, the locking motor 321 is de-excited, the motor rotating block 322 rotates anticlockwise under the action of the elastic potential energy released by the torsion spring 325, and stops at the position facing the bolt 323 on the plane under the action of the limiting block 326, so that the bolt 323 can retract into the movement space of the lock cylinder 310.

Referring to fig. 2 to 4, in the present embodiment, the passive electronic lock is a padlock, the locking portion 200 is a U-shaped locking hook, and the head end and the tail end of the locking portion 200 are both provided with second locking grooves 210. A compression spring 500 is provided between the head end of the locking part 200 and the lock body 100. The locking buckle mechanism includes a ball stopper 311, a ball 312 passage is provided in the lock body 100, and a ball 312 is provided in the ball 312 passage. In this embodiment, two ball 312 channels are disposed on two sides of the ball stopper 311 in pairs, and one ball 312 is disposed in each ball 312 channel. The ball stopper 311 may move along with the lock core 310, when the lock core 310 moves to the unlocking position, the ball 312 has a certain movement space in the passage of the ball 312, and the locking portion 200 may move under the action of the compressed elastic member 500 to discharge the ball 312 from the second locking groove 210, so that the locking portion 200 is separated from the locking hole 110, as shown in fig. 3. When the cylinder 310 moves to the locking position, the ball stopper 311 pushes the ball 312 into the second locking groove 210, which prevents the locking portion 200 from releasing from the locking hook under the action of the compression elastic member 500, as shown in fig. 2.

Referring to fig. 2 and 4, in the embodiment, the ball stopper 311 is a cylinder structure, two concave portions are disposed on opposite sides of the ball stopper 311, and the length of the ball 312 channel is smaller than the diameter of the ball 312. When the cylinder 310 moves to the unlocking position, the two concave parts are respectively communicated with the two ball 312 channels, and the ball 312 can be squeezed into the concave parts by the locking part 200, so that the locking part 200 is separated from the lock hole 110. When the cylinder 310 moves to the locking position, the ball 312 is pushed into the second locking groove 210 by the side surface of the ball stopper 311, so that the locking portion 200 cannot be separated from the locking hole 110 by the compression of the elastic member 500. When the locking part 200 is separated from the lock hole 110, because the length of the passage of the ball 312 is smaller than the diameter of the ball 312, part of the ball 312 is pushed into the concave part of the ball stopper 311 under the action of the locking rod, the movement of the ball stopper 311 can be limited, and further the movement of the lock core 310 is limited, when the locking part 200 is not pressed into the lock hole 110, the computer key cannot be rotated to rotate the lock core 310 to the locking position, and the occurrence of false locking is further prevented.

Referring to fig. 1 and 4, in the present embodiment, the position sensor 410 is a hall sensor in the proximity position sensor 410, and the position sensor 410 is disposed on the cylinder core 310 and moves together with the cylinder core 310. The trigger mechanism 420 corresponds to a magnetic steel disposed on the mechanical locking mechanism 330. When the cylinder 310 moves to the locked position, the magnetic steel is aligned with the hall sensor. In the present embodiment, the mechanical locking mechanism 330 is a blade lock cylinder, and the cylinder core 310 is rotatably disposed in a cylindrical sleeve of the mechanical locking mechanism 330. The blade 331 of the mechanical locking mechanism 330 extends into the cylinder 310 through a plurality of waist holes arranged along the circumference of the cylinder 310 to contact with a computer key. The blade cylinder also restricts the movement of the cylinder core 310 in this embodiment, and when the computer key is mated with the blade 331, the blade cylinder unlocks the restriction of the cylinder core 310. When the cylinder 310 is not in the unlocking position or the locking position, the blade 331 of the blade lock cylinder can clamp the computer key in the cylinder, so that the cylinder cannot be pulled out.

The passive electronic lock provided by the embodiment of the invention has the electromechanical integrated lock core provided by the embodiment of the invention, the motion of the lock liner is unlocked through the electronic locking mechanism, and the locking action on the locking part is realized by driving a corresponding mechanism through rotating a computer key, so that the passive electronic lock has the advantages of difficulty in breaking the electronic lock core, firm locking of the mechanical lock core and no false locking phenomenon.
