[0001] The present invention relates to the technical field of locks, and in particular to a lock core, a key and a lock core system. Background Art

[0002] Prior art lock cylinders consist of a body with a keyhole and a pin. To unlock the lock, a key is inserted into the keyhole and moves the pin, which in turn rotates the cylinder. Because the keyhole directly reaches the pin, this structure allows for technical unlocking. For example, metal, rubber, or gel can be inserted into the keyhole to simulate the key moving the pin and rotating the cylinder. This results in poor anti-theft performance and low security.

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The following combination Figures 1 to 9 , describing embodiments of the present invention.

[0037] According to an embodiment of the present invention, on the one hand, a lock core 1 is provided, such as Figure 1As shown, it includes a lock core body 101, a blocking member 102, a driving mechanism, a first sensing element 104 and a controller, wherein a lock hole 1011 is provided on the lock core body 101, and a pin 1012 is provided on one side of the lock core body 101; the blocking member 102 is provided on the lock core body 101 on the side of the pin 1012 close to the entrance of the lock hole 1011, and the blocking member 102 separates the lock hole 1011 into a first hole 10111 and a pin hole 10112; the blocking member 102 can be switched between an unlocked state and an anti-theft state; in the unlocked state, the blocking member 102 moves back to the lock hole 1011 to connect the pin hole 10112 with the first hole 10111; in the anti-theft state, the blocking member 102 moves to the lock hole 1011 to separate the ball hole 10112 from the first hole 10111; the driving mechanism is arranged on the lock core body 101, and one side of the driving mechanism is connected to the blocking member 102; the first sensing element 104 is arranged on the lock core body 101 located on one side of the first hole 10111; the controller is electrically connected to the first sensing element 104 and the driving mechanism; the key 2 matching the lock core 1 is provided with a second sensing element 202, and when the key 2 is inserted into the first hole 10111, the first sensing element 104 is suitable for identifying the second sensing element 202, and the controller controls the driving mechanism to drive the blocking member 102 to switch to the unlocking state; when the key 2 is pulled out, the controller controls the driving mechanism to drive the blocking member 102 to switch to the anti-theft state.

[0038] The lock core 1 of this structure has a blocking member 102 on the lock core body 101. When the lock core 1 is in the locked state, the blocking member 102 blocks the first hole 10111 and the ball hole 10112 to prevent the unlocking device from extending into the ball hole 10112 and moving the ball 1012 in the locked state. When the lock core 1 is unlocked by the key 2, a second sensing element 202 is provided on the key 2, and the key 2 is inserted into the first hole 10111. The first sensing element 104 recognizes the second sensing element 202, and the controller compares the data of the second sensing element 202 with the stored information. After the information matches, the controller controls the driving mechanism to operate, and the driving mechanism drives the blocking member 102 to move back to the lock hole 1011. The first hole 10111 is connected to the ball hole 10112, and the key 2 is inserted into the ball hole 10112 to move the ball 1012 to unlock; when the key 2 is pulled out after unlocking, the second sensing element 202 passes through the first sensing element 104 again, and the controller knows that the key 2 has been pulled out. The controller controls the driving mechanism to operate, so that the driving mechanism drives the blocking member 102 to reset to the lock hole 1011, and the blocking member 102 separates the first hole 10111 from the ball hole 10112 to prevent the locked state from being unlocked by the unlocking device. The blocking member 102 separates the first hole 10111 from the pin hole 10112 to effectively prevent the locked state from being unlocked by the unlocking device, thereby effectively improving the anti-theft performance and safety performance of the lock core 1.

[0039] In one embodiment, the drive mechanism includes a lifting drive mechanism that extends vertically and is disposed on the lock cylinder body 101. The blocking member 102 is liftably disposed on the lock cylinder body 101. The lifting drive mechanism extends vertically, with its extension direction perpendicular to the axial direction of the lock hole 1011. This makes it difficult for foreign objects to pass through the lock hole 1011 and reach the lifting drive mechanism. This effectively prevents the use of a tool inserted into the lock hole 1011 to forcibly rotate the drive mechanism to rotate the driving end of the drive mechanism and thereby drive the blocking member 102 to move, further enhancing the security of the lock cylinder 1.

[0040] In other embodiments, the driving mechanism includes a second motor and a worm gear mechanism, the worm gear mechanism includes a worm gear with a horizontally arranged shaft hole and a second worm gear extending vertically, the shaft of the second motor extends horizontally and is connected to the turbine shaft, the second worm gear is connected to the blocking member 102, and the blocking member 102 is slidably arranged on the lock cylinder body 101. The second motor drives the turbine to rotate to drive the second worm gear and the blocking member 102 to rise and fall.

[0041] In one embodiment, Figure 2 As shown, the lifting drive mechanism includes a rotary driver 1031, a first worm 1032, and a rack structure 1033. The rotary driver 1031 is mounted on the lock cylinder body 101 and is electrically connected to a controller. The first worm 1032 extends vertically, one end of which is connected to the driving end of the rotary driver. The rack structure 1033 extends vertically on the blocking member 102, with the helical teeth of the first worm 1032 meshing with the rack structure 1033. When a key 2 matching the lock cylinder 1 is inserted into the keyhole 1011, the controller activates the rotary driver, which rotates the first worm 1032, which in turn drives the rack structure 1033 upward, thereby raising the blocking member 102. The helical teeth of the first worm 1032 have a shallow inclination angle. When the rotary driver is inoperative, external forces are unlikely to pry the blocking member 102, thereby enhancing the anti-theft and security of the lock cylinder 1.

[0042] In other embodiments, the lifting drive mechanism may further include an electric cylinder or an electric push rod, and the driving end of the electric cylinder or the electric push rod is directly connected to the blocking member 102 to drive the blocking member 102 to move up and down.

[0043] Specifically, in one embodiment, the rotation driver is a first motor, and the rack structure 1033 is a plurality of tooth-shaped portions integrally formed on the blocking member 102 , and the plurality of tooth-shaped portions are arranged at intervals along the vertical direction.

[0044] Optionally, in one embodiment, the longitudinal section of the locking hole 1011 is rectangular, and correspondingly, the blocking member 102 is in the shape of a rectangular plate.

[0045] like Figure 1As shown, the controller includes a drive control unit 1051, a lock core main control control unit 1052 and a power conversion unit 1053, wherein the drive control unit 1051 is electrically connected to the drive mechanism; the lock core main control control unit 1052 is electrically connected to the drive control unit 1051 and the first sensing element 104; the power conversion unit 1053 is electrically connected to the drive control unit 1051 and the lock core main control control unit 1052; the drive control unit 1051, the lock core main control control unit 1052 and the power conversion unit 1053 are all arranged on the lock core body 101. The power conversion unit 1053 converts the voltage of the power supply into the voltage required by the drive control unit 1051 and the lock core main control unit 1052. The key 2 is inserted into the first hole 10111, and the first sensing unit senses the second sensing unit. The lock core main control control unit 1052 compares the data of the second sensing unit with the stored data. If the data match, the lock core main control control unit 1052 sends a signal to the drive control unit 1051, and the drive control unit 1051 supplies power to the first motor. The first motor runs and drives the blocking member 102 to rise; after the key 2 is pulled out, the lock core main control control unit 1052 knows that the key 2 is pulled out and sends a signal to the drive control unit 1051. The drive control unit 1051 controls the first motor to rotate in the opposite direction to lower the blocking member 102, thereby realizing the linkage between the blocking member 102 and the insertion and removal of the key 2, and realizing the accurate, fast and automatic lifting and lowering of the blocking member 102.

[0046] Specifically, the drive control unit 1051 includes a motor drive chip, the lock core main control control unit 1052 includes a lock core 1 main control chip, and the power conversion unit 1053 includes a lock core 1 power chip. Figure 1 As shown, optionally, in one embodiment, a recess is provided on the lock cylinder body 101 above the first hole 10111, and the lock cylinder 1 power supply chip, motor driver chip, and lock cylinder 1 main control chip are sequentially arranged on the bottom wall of the recess. An escape hole is provided on the wall of the lock hole 1011, and a slide groove is provided on the lock cylinder body 101. The blocking member 102 rises and falls along the escape hole and the slide groove.

[0047] like Figure 1As shown, in one embodiment, a first positive conductive member 106 and a first negative conductive member 107 are provided on the wall of the first hole 10111. The first positive conductive member 106 and the first negative conductive member 107 are electrically connected to the drive mechanism. The key 2 is provided with a key 2 power supply and a second positive conductive member and a second negative conductive member electrically connected to the key 2 power supply. The first positive conductive member 106 and the first negative conductive member 107 are adapted to conduct electricity with the second positive conductive member and the second negative conductive member, respectively. Under normal circumstances, the lock cylinder 1 is powered by the lock body power supply. When the lock body power supply is depleted, the key 2 is inserted into the lock hole 1011. The first positive conductive member 106 contacts and conducts electricity with the second positive conductive member, and the first negative conductive member 107 contacts and conducts electricity with the second negative conductive member. This allows the key 2 power supply to power the lock cylinder 1, ensuring that the blocking member 102 can be raised and lowered normally, and that the lock can be unlocked normally even when the lock body power supply is depleted.

[0048] Preferably, in one embodiment, a first positive conductive member 106 is provided on two opposite side walls of the lock hole 1011, and a second negative conductive member is provided on the other two opposite side walls. The second positive conductive member and the second negative conductive member on the key 2 are respectively arranged corresponding to the first positive conductive member 106 and the second negative conductive member. The key 2 can be inserted into the lock hole 1011 with the front side facing up or the back side facing up to conduct the first positive conductive member 106 and the first negative conductive member 107 to supply power to the first motor, and the unlocking operation is highly convenient.

[0049] For example, in one embodiment, two first positive conductive members 106 are respectively arranged on the hole walls on the left and right sides of the entrance of the lock hole 1011, and two first negative conductive members 107 are arranged on the hole walls on the upper and lower sides of the lock hole 1011. The first positive conductive member 106 is connected to the positive pole of the lock cylinder 1 power chip, and the first negative conductive member 107 is connected to the negative pole of the lock cylinder 1 power chip to supply power to the lock cylinder 1 power chip, and the lock cylinder 1 power chip then converts the power supply voltage into the voltage required by the lock cylinder 1 main control chip and the motor drive chip.

[0050] Optionally, in one embodiment, the first sensing element 104 is disposed at the bottom of the lock hole 1011 ; the first sensing element 104 is an NFC sensing coil.

[0051] In other embodiments, the first sensing element 104 may also be any other sensing element having an identity recognition function.

[0052] According to an embodiment of the present invention, on the other hand, Figures 3 to 7 As shown, a key 2 is further provided, which matches the lock cylinder 1 and is used to unlock or lock the lock cylinder 1. The key 2 includes a key body 201 and a second sensing element 202, and the second sensing element 202 is provided on the key body 201.

[0053] When the key 2 is inserted into the lock hole 1011, the first sensing element 104 senses and identifies the second sensing element 202, and the first sensing element 104 sends a signal to the lock core 1 main control chip. After the lock core 1 main control chip determines that the data matches, it controls the first motor to drive the blocking member 102 to rise; when the key 2 is pulled out, the lock core 1 main control chip controls the blocking member 102 to descend.

[0054] like Figure 3 As shown, the key body 201 includes an unlocking component and a accommodating box 2014, wherein a second positive conductive member and a second negative conductive member are provided on the outer wall of the unlocking component; a first positive conductive member 106 and a first negative conductive member 107 are provided on the hole wall of the first hole 10111; when the unlocking component is inserted into the first hole 10111, the second positive conductive member is connected to the first positive conductive member 106, and the second negative conductive member is connected to the first negative conductive member 107; the accommodating box 2014 is connected to the unlocking component, and the accommodating box 2014 is suitable for accommodating the key 2 power supply, and the key 2 power supply is electrically connected to the second positive conductive member and the second negative conductive member.

[0055] Under normal circumstances, the lock core 1 is powered by the lock body power supply. When the lock body power supply is out of power, the key 2 is inserted into the lock hole 1011, the first positive conductive member 106 contacts and turns on the second positive conductive member, and the first negative conductive member 107 contacts and turns on the second negative conductive member, so that the lock core 1 is powered by the key 2 power supply, ensuring normal unlocking when the lock body power supply is out of power.

[0056] like Figure 3 、 Figure 6 and Figure 7 As shown, the housing 2014 is cylindrical and the power source is a button battery. The positive electrode of the button battery is electrically connected to the second positive conductive member via the first conductive member 2015, and the negative electrode of the button battery is electrically connected to the second negative conductive member via the second conductive member 2016. The button battery is compact and conveniently accommodated in the key body 201. It is also easy to replace the button battery.

[0057] In other embodiments, the housing box 2014 may also be cylindrical, with cylindrical batteries disposed therein.

[0058] Optionally, in one embodiment, the accommodating box 2014 includes an upper box body and a lower box body, each of which is provided with an accommodating cavity, and each of which is provided with a button battery, the negative pole of the upper button battery is facing upward, and the negative pole of the lower button battery is facing downward, the positive poles of the two button batteries are facing each other and in contact, and the negative poles of the two button batteries are electrically connected so that the two button batteries are powered in parallel, thereby doubling the capacity of the key 2 power supply under inconvenient voltage conditions and increasing the power supply time of the key 2 power supply.

[0059] like Figure 4As shown, in one embodiment, the unlocking component includes two unlocking pattern portions 2011 arranged opposite to each other and sealing plate portions 2012 arranged opposite to each other on both sides of the unlocking pattern portion 2011, wherein the unlocking pattern portion 2011 serves as a second negative conductive member and the sealing plate portion 2012 serves as a second positive conductive member; the sealing plate portion 2012 is arranged between the two unlocking pattern portions 2011, and an insulating member is provided between the sealing plate portion 2012 and the unlocking pattern portion 2011; the second sensing element 202 is arranged in a cavity surrounded by the insulating member and the sealing plate portion 2012.

[0060] The unlocking pattern 2011 and the sealing plate 2012 are both made of metal. The unlocking pattern 2011 and the sealing plate 2012 on the outside of the unlocking assembly directly serve as the second negative and second positive conductive members. These large-area second negative and second positive conductive members effectively conduct electricity between the first positive and first negative conductive members 106 and 107 when inserted into the lock hole 1011. Furthermore, the unlocking pattern 2011 and the sealing plate 2012 directly serve as the second negative and second positive conductive members. These members are structurally strong and resist loosening, ensuring effective electrical conduction. The second sensing element 202 is located within the cavity enclosed by the insulating member and the sealing plate 2012 to prevent damage to the second sensing element 202 and ensure proper unlocking.

[0061] In other embodiments, the second positive conductive member and the second negative conductive member may also be conductive sheets provided on the outer wall of the key body 201 .

[0062] Specifically, see Figure 4 The unlocking pattern portion 2011, the sealing plate portion 2012 and the first insulating member 2013 are all in the shape of rectangular plates, and the unlocking pattern portion 2011, the sealing plate portion 2012 and the first insulating member 2013 can be fixed by gluing.

[0063] In one embodiment, the key 2 further includes a second insulating member 203 having a second sensing element 202 disposed therein. The second insulating member 203 is disposed between the two sealing plates 2012 and the two first insulating members 2013. Both the first insulating member 2013 and the second insulating member 203 are made of insulating material.

[0064] In one embodiment, the first sensing element 104 is an NFC sensing coil, and the second sensing element 202 is an IC card.

[0065] like Figure 6 and Figure 7As shown, in one embodiment, the first conductive member 2015 includes a circular portion, a vertical portion, and a horizontal extension portion. The circular portion is provided with a plurality of spherical portions at intervals along the circumference. One side of the spherical portion is embedded in the container 2014, and one side protrudes from the inner wall of the container 2014 to abut against the outer wall of the button battery (i.e., the positive electrode of the button battery); the vertical portion is provided on one side of the circular portion, and the horizontal extension portion is provided at the end of the vertical portion. The two ends of the horizontal extension portion are provided with pins extending toward the sealing plate portion 2012. The sealing plate portion 2012 abuts above the pins to enable the second positive conductive member to conduct electricity to the positive electrode of the button battery. In the upper box body, the vertical portion of the first conductive member 2015 is provided below the circular portion, and the bottom of the vertical portion is connected to the horizontal extension portion; in the lower box body, the vertical portion is provided above the circular portion, and the upper part of the vertical portion is connected to the horizontal extension portion.

[0066] like Figure 6 and Figure 7 As shown, the second conductive member 2016 is in the shape of a pointer, with one side contacting the negative electrode of the button battery and the other side extending toward and contacting the unlocking pattern portion 2011. The first conductive member 2015 of the upper case is located above the button battery, while the first conductive member 2015 of the lower case is located below the button battery.

[0067] According to an embodiment of the present invention, on the other hand, a lock cylinder 1 system is provided, comprising the above-mentioned lock cylinder 1 and the above-mentioned key 2 .

[0068] The working process of the lock cylinder 1 system is as follows Figure 8 As shown, the key 2 is inserted into the lock hole 1011, and the power supply of the key 2 supplies power to the electrical equipment on the lock core 1. The NFC induction coil at the bottom of the lock hole 1011 interacts with the induction coil in the IC card, and the NFC induction coil sends the induction signal to the main control chip of the lock core 1. The main control chip of the lock core 1 controls the operation of the first motor through the motor drive chip. The first motor drives the blocking member 102 to rise, and the key 2 rotates the lock core 1 to unlock; after unlocking, the key 2 is pulled out, the NFC induction coil senses the IC card again, and the first motor drives the blocking member 102 to lower.

[0069] like Figure 9 As shown, in one embodiment, the lock cylinder 1 system further includes a lock body, which is adapted to be provided with a lock body power supply. The lock body power supply is electrically connected to the drive mechanism, that is, the lock body power supply is electrically connected to the first motor. The controller includes a lock body main control unit and a lock cylinder main control unit 1052, which are electrically connected to the lock cylinder main control unit 1052. In a normal state, the lock body power supply supplies power to the first motor. When the lock body power supply is disconnected, the key 2 supplies power to the first motor.

[0070] In one embodiment, the lock body is provided with a lock body power supply chip and other lock body components. The lock body main control unit includes a lock body main control chip, and the lock core main control control unit 1052 includes a lock core 1 main control chip.

[0071] Specifically, if Figure 9 As shown, the lock body power supply is electrically connected to the lock cylinder 1 power chip and the lock body power chip. The lock body power chip is electrically connected to the lock body main control chip and other lock body components to provide power to the lock body main control chip and other lock body components. The lock body main control chip is electrically connected to the lock cylinder 1 main control chip. When the lock cylinder 1 is powered by the lock body power supply, the user can notify the lock body main control chip via Bluetooth or Wi-Fi through a mobile phone app. The lock body main control chip sends a signal to the lock cylinder 1 main control chip. After receiving the command, the lock cylinder 1 main control chip sends a signal to the motor drive chip, causing the first motor to rotate forward or reverse, thereby driving the blocking member 102 to rise or fall. In other words, when the lock cylinder 1 is powered by the lock body power supply, the raising and lowering signal of the blocking member 102 comes from the lock body main control chip controlled by the mobile phone app. When the lock cylinder 1 is powered by the key 2, the raising and lowering signal of the blocking member 102 comes from the NFC induction coil and IC card. The raising and lowering signal of the blocking member 102 can be selected according to actual conditions.

[0072] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
