The intelligent lock cylinder of this embodiment keeps the configuration of key hole and key in order to better adapt current mechanical lock, changes ordinary key into intelligent key, inserts in the key hole equally during the use, then adopts the operation mode of unblanking of intelligent lock, realizes that intelligence is unblanked.

Referring to fig. 1, the smart key cylinder of the present embodiment includes a cylinder 10, a pin tumbler driving mechanism 20, a main control board 30, a smart key 40, and other main components. Wherein, the lock cylinder 10 is provided with a key hole 11 for inserting the intelligent key 40; a marble 16 is arranged in the lock cylinder 10, and the marble 16 is electrically connected with the main control panel 30; the marble driving mechanism 20 drives the marbles 16 to move towards the direction of the key hole 11 under the control of the main control panel 30 so as to be in contact conduction with the intelligent key 40 inserted into the key hole 11, and thus the electric communication between the main control panel 30 and the intelligent key 40 is realized; the main control board 30 generates an unlocking signal after detecting that it is electrically communicated with the smart key 40, and drives an unlocking mechanism in the lock body to act, so that automatic unlocking is realized.

In this embodiment, the lock cylinder 10 may be designed to have a cylindrical or rectangular parallelepiped structure, as shown in fig. 1 and 2. A keyhole 11 is opened at an intermediate position of the lock cylinder 10, and the keyhole 11 preferably extends in a depth direction of the lock cylinder 10, as shown in an extending direction of fig. 2. The lock cylinder 10 is provided with a spring hole 12 in the height direction, one end of the spring hole 12 is communicated with the key hole 11, and the other end of the spring hole 12 penetrates through the lock cylinder 10 and is exposed. The marble hole 12 is provided with a marble 16, and under a natural state, the top of the marble 16 extends out of the lock cylinder 10 to be exposed, and the bottom of the marble 16 is completely retracted in the marble hole 12 and cannot be contacted with the intelligent key 40 inserted into the key hole 11.

As a preferred embodiment, in order to improve the anti-theft coefficient of the lock, a plurality of ball holes 12 are preferably formed in the lock cylinder 10, as shown in fig. 2. The bullet holes 12 may be all located above the key hole 11, may be all located below the key hole 11, and may also be distributed on the upper and lower sides of the key hole 11. Each pin 16 is installed in each pin hole 12, and the height of the part of each pin 16 exposed out of the lock cylinder 10 is preferably configured to be different or not equal, so that the displacement of each pin 16 when the pin is pushed by the pin driving mechanism 30 to move towards the key hole 11 is different, thereby increasing the matching difficulty and improving the safety factor of the lock.

In some embodiments, the pin 16 may be constructed by mating a pin 13, a piston 14, and a hydraulic probe 15, as shown in fig. 2. Wherein, the spring column 13 partially exposes the lock cylinder 10 and is electrically connected with the main control board 30 through a wire. The piston 14 is located between the bullet column 13 and the hydraulic probe 15, when the bullet column 13 receives the thrust of the bullet driving mechanism 30, the bullet column 13 pushes the piston 14 to move, and presses the hydraulic oil in the hydraulic probe 15, so that the probe extends out of the bullet hole 12 and is in contact conduction with the smart key 40.

Of course, the pin 16 may also be a spring-type Pogo pin, and the embodiment is not limited to the above example.

In order to improve the stability and effectiveness of the pins 16 and the smart key 40 during contact conduction, it is preferable that the metal insertion portion 42 of the smart key 40 is provided with concave bases 43 equal in number to the number of the pins 16, as shown in fig. 2. Each concave base 43 receives one pin 16, and the pins 16 are preferably designed to be electrically conducted after contacting the bottom of the concave base 43, so that the effective displacement of each pin 16 can be determined more accurately, and the safety of the lock can be improved.

For the smart lock cylinder with the marbles 16 distributed up and down, the top surface and the bottom surface of the metal insertion portion 42 of the smart key 40 may be respectively provided with the concave bases 43, as shown in fig. 2, and the concave bases 43 provided on the top surface and the bottom surface are preferably staggered from each other in the vertical direction, so as to ensure that the metal insertion portion 42 of the smart key 40 has sufficient strength and is not easy to break. The depth of each concave base 43 may be equal or different, and may be specifically designed to cooperate with the pin 16 and the pin driving mechanism 30.

In this embodiment, the pin driving mechanism 30 can be formed by a special-shaped rack 21, a worm 26, a gear set and a motor 27, as shown in fig. 1. The special-shaped rack 21 can be designed by adding the lug 23 on the basis of the conventional rack 21. Specifically, the projection 23 may be disposed on a surface of the modified rack 21 away from the rack surface 22, and the projection 23 may contact the pin 16 and push the pin 16 to move. The worm 26 is located on one side of the rack face 22 of the shaped rack 21 and meshed with teeth on the rack face 22, and the motor 27 drives the worm 26 to rotate through the gear set, so as to drive the shaped rack 21 to carry the projection 23 to move linearly, so as to push the marble 16 to move towards the direction of the keyhole 11.

As a preferred embodiment, the worm 26, gear set and motor 27 may be mounted on a frame 28, and the frame 28 may be fixedly mounted in the lock body. The gear set comprises two sets of gears 24, 25 engaged with each other, wherein the first set of gears 24 can be coupled to the rotation output shaft of the motor 27, and the motor 27 is used to drive the first set of gears 24 to rotate. The second set of gears 25 may be coupled to the axis of rotation of the worm 26 and driven in rotation by the first set of gears 24, which in turn drives the worm 26 in rotation.

In some embodiments, the first set of gears 24 and the second set of gears 25 each include two gears, and are disposed on opposite sides of the motor 27 and the worm 26 along the axial direction of the motor 27 and the worm 26 to improve the smoothness of the transmission.

In some preferred embodiments, the number of the protrusions 23 may be equal to the number of the pins 16, or may be greater than the number of the pins 16. The heights of the respective bumps 23 may be completely different or partially equal. When the motor 27 indirectly drives the special-shaped rack 21 to move to reach the preset position, the height of each bump 23 in contact with the marble 16 just meets the design condition of pushing the marble 16 into the concave base 43 of the smart key 40 and just in contact conduction with the bottom of the concave base 43, and the heights of other bumps cannot meet the design condition.

For an intelligent lock core with pins 16 uniformly distributed on the upper and lower sides of a lock cylinder 10, two sets of pin tumbler driving mechanisms 20 can be arranged, wherein one set is arranged above the lock cylinder 10 and used for pushing the pins 16 positioned above to move, as shown in fig. 1; a further set of tumbler drive mechanisms is disposed below the lock cylinder 10 (not shown) for moving the tumblers 16 located therebelow. The motors 27 in the two sets of pin tumbler driving mechanisms 20 can be controlled by the main control board 30 to operate, but the rotation numbers of the two motors 27 can be set to be different, so that the linear displacement quantities for driving the upper and lower opposite racks 21 are different. Therefore, the anti-theft coefficient of the lock can be increased by pushing the upper marble 16 and the lower marble 16 to move by using the lugs 23 at different positions on the two opposite racks 21.

In this embodiment, the main control board 30 is preferably installed on the rack 28, and is disposed with an MCU (hereinafter referred to as a lock cylinder MCU), and a wireless module, a motor driving circuit and a motor driving circuit connected to the lock cylinder MCU, as shown in fig. 5. Wherein, the lock core MCU can be in wireless communication with the intelligent key 40 through the wireless module. The smart key 40 includes a hand-held portion 41 having an insulating housing, and the hand-held portion 41 is connected to the metal insertion portion 42. An information input module for receiving user input information is arranged on the handheld portion 41, and the information input module can be a key pad 44, as shown in fig. 3, for receiving an unlocking password input by a user; or alternatively a fingerprint identification module or card reader 45, as shown in fig. 4, to collect the user's fingerprint or card swiping information. The handheld portion 41 may further include an MCU (hereinafter referred to as a key MCU), as shown in fig. 5, connected to the information input module 44/45, processing the user input information collected by the information input module 44/45 into user data, and sending the user data to the cylinder MCU in the main control board 30 through the wireless module built in the handheld portion 41 to verify the validity of the user information.

When unlocking the lock, the metal insertion portion 42 of the smart key 40 is inserted into the keyhole 11 of the lock cylinder 10, and the user inputs user information to the information input module 44/45 of the smart key 40, processes the user information into user data using the key MCU, and wirelessly transmits the user data to the main control board 30. The lock core MCU in the main control board 30 verifies the received user data, if the received user data is not consistent with the prestored user data, the lock core MCU is judged as an illegal user, the unlocking operation is not executed, or an alarm prompt can be further sent out; if the data of the user is not consistent with the prestored user data, the user is judged to be a legal user, a control signal is output, the motor driving circuit is controlled to drive the motor 27 to operate, the motor 27 drives the worm 21 to rotate through the gear set, further, the special-shaped rack 21 is driven to carry the bump 23 to move linearly to a preset position, the bump 23 is used for pushing the marble 16 to move towards the direction of the key hole 11, and the marble is inserted into the concave base 43 on the metal insertion part 42 of the intelligent key 40 and is in contact conduction with the bottom surface of the concave base 43. Thus, the key cylinder MCU is electrically connected to the key MCU through the pins 16 and the metal insertion portion 42 of the smart key 40. The lock core MCU outputs an unlocking signal after detecting that the lock core MCU is electrically communicated with the intelligent key 40, and controls the unlocking mechanism to unlock.

As a preferred embodiment, the lock core MCU is preferably designed to be connected with each marble 16 through a plurality of IO ports thereof, and the number of the IO ports is the same as that of the marbles 16; each marble 16 is communicated with the multi-channel IO ports of the key MCU through the concave base 43 in a one-to-one correspondence manner. The configuration key MCU sends preset electric signals (such as switching value signals) through the multi-channel IO ports, and the lock cylinder MCU generates unlocking signals when detecting that the multi-channel IO ports of the lock cylinder MCU receive the preset electric signals (such as high level) to control the unlocking mechanism to unlock. By adopting the design mode, whether each marble 16 is accurately contacted and conducted with the matched concave base 43 can be detected, so that the use safety of the lockset can be further improved.

When the intelligent lock cylinder of the embodiment is installed on a mechanical lock, for most of the current mechanical locks, the spring bolt of the intelligent lock cylinder generally adopts a spring and a cam to control the expansion and contraction of the spring bolt. In order to adapt to the structural design of the mechanical lock, in the embodiment, a motor is preferably arranged in the lock body as an unlocking mechanism, the motor is coupled with the cam, and the motor is used for driving the cam to rotate so as to replace a mechanical lock unlocking mode that a key is rotated by a hand to drive the cam to rotate, thereby achieving the purpose of automatic unlocking.

Particularly, when the tool to lock is in the lock state, the spring bolt can stretch out the lock body under the effect of the elastic restoring force of spring. When the lock core MCU outputs an unlocking signal, as shown in fig. 5, the motor driving circuit arranged on the main control board 30 is controlled to operate, and the driving motor carries the cam to operate, so that the protruding portion of the cam abuts against the lock tongue, and pushes the lock tongue to press the spring to move toward the inside of the lock body, until the lock tongue is completely retracted into the lock body, the motor is controlled to stop rotating, and the unlocking state is maintained. After the unlocking state is kept for a set time, the lock cylinder MCU can control the motor to carry the cam to rotate for a certain angle again through the motor driving circuit, so that the protruding part of the cam leaves the lock tongue. At the moment, the lock tongue can pop out of the lock body under the action of the elastic restoring force of the spring, and the aim of automatically locking the door is fulfilled.

The intelligent lock core of the embodiment can be matched with part of components in the mechanical lock, and conversion from the mechanical lock to the intelligent lock is realized. Of course, the intelligent lock cylinder of the embodiment may also be configured with accessories such as a dedicated lock body, a dedicated lock tongue, and the like to form an independent intelligent lock.

It should be noted that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should also make changes, modifications, additions or substitutions within the spirit and scope of the present invention.
