Therefore, an electrical connection is established among the first conductor 45, the sensing element 51, the second conducting bead 57, the second bars 61, the conducting seat 67 and the master circuit board 91.
- the motor 69 is activated by the master circuit board 91 and the motor 69 drives the threaded rod 71 to rotate, which in turn drives the actuator 75 and the second clutch 33 to move toward the key 99 via the nut 73.
- the cavity 37 of the second clutch 33 is aligned with the extension 29 of the first clutch 25, as shown in Figure 4 .

- the lock core 7 is able to rotate inside the body 1.
- the first clutch 109 has an indent 113 corresponding to the protrusion 121 of the second clutch 115 and two opposed first blocks 111 respectively formed on a side of the first clutch 109 to be received in the first slit 83 of the rotor 81.
- the third clutch 133 has two second blocks 137 respectively formed on a side face of the third clutch 133 to be received in the first slit 83 of the rotor 81 and an elongated hole 141 defined in a side of the third clutch 133.
- a through hole 135 is defined in a front face of the third clutch 133 to communicate with a threaded hole 145 of a seat 143 after the seat 143 is received in the third clutch 133 from the elongated hole 141. Thereafter, a projection 147 formed with the seat 143 is extended out of the elongated hole 141.
- Both the third clutch 133 and the seat 143 are received in the rotor 81 with the two second blocks 135 received in the first slit 83.

- the rotor 81 further has a driving element, positioning block 153 and a conductor 149 having two opposed arms 151 respectively formed on a side of the conductor 149.
- the positioning block 153 has two opposed cutouts (not numbered) to securely receive therein the conductor 149 and allow the two arms 151 to extend out of the positioning block 153.
- the driving element is a motor 69 having a motor shaft extending through a motor bracket 155 to be threadingly connected to a threaded bolt 71 and the threaded hole 145 of the seat 141.
- the motor 69, the motor bracket 155, the third clutch 133, and the seat 143 are assembled inside the rotor 81 to have the projection 147 positioned between the two arms 151. Then the second rotation circuit board 127 is positioned in the rotor 81 by screws extending through the third cutouts 129 of the second rotation circuit board 127 and into the rotor 81.
- a bolt 163 is provided to extend through a clamping ring 161 and into the hole 811 of the rotor 81 so as to position the rotor 81 with the clamping ring 161.
- a ring 157 having teeth formed on an inner side of the ring 157 is assembled with the body 1 via a second slit radially defined in the barrel 5 of the body 1 to allow the rotor 81 to extend through the ring 157 and the cam 77 which is received in the cutout 3 of the body 1 . Screws are applied to secure the cam 77 to an outer periphery of the rotor 81.
- a sensor 159 is mounted on the outer periphery of the rotor 81 and the sensor 159 is facing the teeth of the ring 157 after the rotor 81 is received in the barrel 5 of the body 1.

- the motor 69 is able to drive the threaded bolt 71 so as to move the seat 143, which in turn drives the third clutch 133 to move. Movement of the third clutch 133 moves the first clutch 109 via the second spring 139. Because the projection 147 of the seat 143 is received in the side slit 85 of the rotor 81, the movement of the seat 143 allows the projection 147 to move away from or into the side slit 85. Meanwhile the first blocks 137 and the second blocks 111 are also moved into or away from the first slit 83 of the rotor 81.
- the rotor 81 When the projection 147 is extended out of the side slit 85 and the first blocks 137 and the second blocks 111 are moved into the first slit 83, the rotor 81 can not be rotated. However, when the first blocks 137 and the second blocks 111 are moved out of the first slit 83, the rotor 81 can be rotated. When the rotor is rotated, the boss 79 is moved in the cutout 3 to drive a different locking device (not shown).
- the lock mechanism further has an alarm system to sound an alarm when there is an unauthorized person trying to unlock the lock mechanism so as to enhance the safety of the lock mechanism.
- a rotation seat 89 there is further provided a rotation seat 89.
- the rotation seat 89 has a master circuit board 91, a battery 93, a buzzer 95, and a cover 97 provided in front of the rotation seat 89.
- the battery 93, the buzzer 95, and the master circuit board 93 are electrically connected with one another and the master circuit board 91 is electrically connected to the second rotation circuit board 127 and the sensor 159.
- a key 99 as shown in Figure 7 , provided with embedded circuit includes a body 101, a chip 105 formed in the body 101 and having a conducting plate 103 integrally formed on the chip 105 and an encapsulation (not shown) enclosing the chip 105 inside the body 101 to avoid damage to the chip 105.
- the contacts 131 on the first rotation circuit board 123 and the second rotation circuit board 127 are able to send signals to the motor and the clutch device so as to drive the lock mechanism.
- the lock mechanism When the lock mechanism is in a locked status, there will be two different locking mechanisms to provide the desired locking effect, namely the conventional latching mechanism in the lock core 7 and the coupling device. If a user is trying to unlock the lock mechanism, the user will have to unlock the lock core 7 and the clutch device of the lock mechanism sequentially, otherwise the buzzer 95 will sound an alarm to warn the security guard that there is an illegal action going on. To be more specific of the operation of the lock mechanism, it is to be noted that before the key 99 is inserted into the lock core 7, the multiple tumblers will lock the lock core 7 to prevent the lock core 7 from rotation such that the lock mechanism is locked.

Abstract
Description
- The present invention relates to a cylinder lock assembly having a mechanical and electronic locking function so as to provide two locking capabilities.
- In general, a mechanical lock has multiple tumblers movably received in a lock core that is securely received inside a lock body. Thus, only a proper key inserted into a keyway defined in the lock core is able to activate movement of the tumblers. Therefore, rotation of the key is able to drive the lock core to rotate accordingly. Despite the varieties of mechanical locks, all the mechanical locks provide only a single locking function.
- A conventional electrical lock includes a sensing card and a lock having a sensing unit to sense the information recorded on the sensing card so as to unlock the lock. This electrical lock, too, has only a single locking function and cannot provide sufficient security as required. As a result, the current locks, mechanical locks or the electrical locks, can only provide a single locking function and not dual locking functions to enhance security.
- A lock mechanism having a mechanical lock and electronic locking components is known from each of
EP-A-0 401 647 ,EP-A-0 462 316 andEP-A- 0 243 586 .EP-A-0 401 647 andEP-A-0 462 316 in particular disclose a cylinder lock assembly having an electronic key. The cylinder lock body has a cutout defined in a central portion of the body to divide the body into two barrels. A cylinder lock core is received inside the body and has multiple tumblers movably received in the lock core and driven by the key, rotation of the key causing corresponding rotation of a cam which is movably received in the cutout of the body. - The electronic key of
EP-A-0 401 647 has a code stored on a chip and a conductor connected to the chip. The cylinder lock core has an engagement bead engageable with the conductor. The cylinder lock includes a spring-loaded sliding bolt, blocked by a pivoting detent, for locking the cam and thus preventing rotation of the cylinder lock core. When a key having the right code is introduced into the cylinder lock core, an unlocking signal is sent to an electromagnet, which releases the detent, so that the sliding bolt is retracted and the lock core and the cam can be turned by the key. -
EP-A-0 243 586 discloses a cylinder lock assembly comprising a cylinder lock and an electronic key. A cam is movably received in the cutout of the cylinder body. A free-rotatable cylinder lock core is received inside the cylinder lock body. When a key having the right code is introduced into the cylinder lock core, a coupling device comprising a clutch is operated by an electromagnet for coupling the cylinder lock core with the cam, so that the cam can be rotated by the key. - A primary objective of the present invention is to obviate the shortcoming of the conventional lock and to improve the lock core adopted from an electronic lock to achieve dual protection effect and hence the novelty and industrial application requirement is met.
- A secondary objective of the present invention is to accomplish two different protection effects with simplified structure and low manufacture cost such that the market requirements is met and industrial value is high.

Figures 1 and2 , a cylinder lock assembly constructed in accordance with an embodiment of the present invention comprises a cylinder lock body 1, a lock core 7, arotor 81, asensing device 39, adriving element 69 and a coupling device composed of afirst clutch 25 and asecond clutch 33. The cylinder body 1 has ahollow barrel 5 and a cutout 3 dividing thebarrel 5 into two halves to receive therein acam 77 having aboss 79 formed on a bottom of thecam 77. A firstradial slit 10 and a secondradial slit 102 are respectively formed on a front portion and a rear portion of thebarrel 5. - The lock core 7 is a hollow cylinder and has two
opposed paths 11 respectively defined in parallel to a longitudinal axis of the cylinder in a side periphery of the lock core 7, apassage 13 axially defined in the side periphery of the lock core 7 and agroove 19 defined in a proximal end of the lock core 7. Thepassage 13 is provided to receive therein apad 15, anabutting element 23 that engages with thepad 15 and acover 232. Thepad 15 has a throughhole 17 defined through thepad 15 to receive therein an engagement bead 231 which is engaged with theabutting element 23. Thecover 232 is provided to secure the abuttingelement 23 and the engagement bead 231 inside thepad 15. The lock core 7 further has multiple tumblers (not shown) inside the lock core 7. Because how the tumblers are moved is well known in the art, detailed description thereof is omitted for brevity. - The
rotor 81 is a hollow cylinder with two open ends. Therotor 81 has twofirst slits 83 each defined in two opposed side periphery of therotor 81 to be parallel to an axial axis of therotor 81 and at least one second slit 85 (two are shown in this embodiment) parallel to the axial axis of therotor 81. Aflange 810 is formed on an outer periphery of therotor 81. - The
first clutch 25 has twofirst bosses 27 respectively formed on two opposed ends of thefirst clutch 25 to be received in the twopaths 11 of the lock core 7 and anextension 29 formed on a side of thefirst clutch 25 and having arecess 31 defined to be parallel to an axial axis of theextension 29. Thesecond clutch 33 has acavity 37 defined to correspond to theextension 29 of thefirst clutch 25 and twosecond bosses 35 to be received in thefirst slits 83 of therotor 81. - The
sensing device 39 includes afirst rotation pad 41, afirst rotation ring 47, asecond rotation pad 59, and asecond rotation ring 53. Thefirst rotation pad 41 has a first bar 43 extending from a side of thefirst rotation pad 41 and afirst conductor 45. Thesecond rotation pad 59 has twosecond bars 61 extending from a rear side of thesecond rotation pad 59 and two apertures 63 defined in a front side of thesecond rotation pad 59 and extending into the apertures 63 respectively. A first conductingbead 55 and a second conductingbead 57 are respectively received in and partially extended out of the two apertures 63. Thefirst rotation ring 47 has anindent 49 defined to movably receive therein anengagement element 51. - The driving element is designated with a
reference numeral 69 and may be a motor. The motor's shaft is connected to a threadedrod 71, which in turn is threaded to anut 73. Thenut 73 is connected to anactuator 75 that is composed of afirst actuator 751, asecond actuator 752, and athird actuator 753. Because how thefirst actuator 751, thesecond actuator 752, and thethird actuator 753 are operated is not the focus of the present invention, detailed description thereof is thus omitted. After the combination between themotor 69 and theactuator 75 via thenut 73, the combination is assembled into amotor bracket 65 whose rear end is connected to amaster circuit board 91. Thereafter, a cylindrical conductingseat 67 is mounted outside themotor bracket 67. Themotor bracket 65 has fourarms 650 formed on a distal end of themotor bracket 65 to correspond to thefirst slits 83 and thesecond slits 85 - In addition, the cylinder lock assembly has an alarming system to sound off an alarm when an unauthorized personnel is trying to inappropriately open the lock so as to upgrade the safety of the lock. In order to achieve the goal, the lock further has a
rotation seat 89. Therotation seat 89 has abattery 93 and abuzzer 95 both received in therotation seat 89 and electrically connected to themaster circuit board 91. Acover 97 is provided to therotation seat 89 to enclose thebattery 93 and thebuzzer 95 inside therotation seat 89. - After the first conducting
bead 55 and thesecond conducting bead 57 are received in the apertures 63 and theengagement sensing element 51 is received in theindent 49 of thefirst rotation ring 47, thefirst rotation ring 47 and thesecond rotation ring 53 are sandwiched between thefirst rotation pad 41 and thesecond rotation pad 59 such that thefirst rotation ring 47 is engaged with thefirst rotation pad 41 and thesecond rotation ring 53 is engaged with thesecond rotation pad 59 and the first conductingbead 55 is extended into the first bar 43. After extending theextension 29 of the first clutch 25 through the rotation pads and the rotation rings, the twofirst bosses 27 of the first clutch 25 are received in thepaths 11 of the lock core 7. Then the lock core 7 is inserted into the front portion of thehollow barrel 5 of the cylinder body 1. A first positioning ring is applied to pass through the first radial slit 10 and thegroove 19 of the lock core 7 so as to secure the lock core 7 inside the cylinder body 1. - The
motor bracket 65 after assembled with themaster circuit board 91, themotor 69, thenut 73, theactuator 75 and the conductingseat 67 enables its fourarms 650 to respectively extend into thefirst slits 83 and thesecond slits 85 so as to allow themotor bracket 65 to be assembled inside therotor 81. Then the twobosses 35 of the second clutch 33 are extended into thefirst slits 83 of therotor 81. Thereafter, therotor 81 is extended into thebarrel 5 of the lock body 1 and pass over thecam 77 that is rested in the cutout 3 in the lock boy 1. A screw or the like is used to secure the position of thecam 77 relative to therotor 81. A positioning ring is applied to extend through the second radial slit 102 of the body 1 and secured to an outer periphery of therotor 81 by engagement with theflange 810 such that therotor 81 will not detach from thebarrel 5 of lock body 1. Lastly therotation seat 89 is assembled to the rear end of the lock body 1. - The first bar 43 of the
first rotation pad 41 is engaged with the abuttingelement 23 and theengagement sensing element 51 is extended into therecess 31 of thefirst clutch 25. At the moment, theengagement sensing element 51 is not in engagement with thesecond conducting bead 57. The twosecond bars 61 of thesecond rotation pad 59 are engaged with one end of the conductingseat 67, which is electrically connected to themaster circuit board 91. Themaster circuit board 91 is electrically connected to themotor 69. Themaster circuit board 91 is able to send a signal to themotor 69 to activate/deactivate themotor 69 and to thebuzzer 95 so that thebuzzer 95 is able to send out an alarm. - A key 99 with a built-in circuit board is shown in
Figure 2 , wherein the key 99 is composed of akey body 101, achip 105, and aconductor 107. Thechip 105 is securely attached to a side of thekey body 101 and then theconductor 107 to attached to a free side of thechip 105. Thereafter, anencapsulation 103 is provided to enclose the combination of thechip 105 and theconductor 107 to avoid contamination. - With reference to
Figures 3 and4 , when the lock of the present invention is in a locked status, a dual protection mechanism is accomplished. That is, the first locking function is accomplished by the conventional latching function of the lock core 7 and the second locking function is accomplished by the clutch of the present invention. When the user is trying to unlock the lock of the present invention, the user has to unlock the conventional latching mechanism and then the clutch to complete the unlocking process of the present invention. If only the first mechanism is unlocked, and an unauthorized person is trying to break the lock, thebuzzer 95 will send out an alarm. If thechip 105 is connected to a security authority, the warning signal will send the alarm to the security authority to have better protection. - To be more specific, before the key is inserted into the lock core 7, the lock of the present invention is locked by the conventional tumblers and thus the lock core 7 is not rotatable. In the meantime, because the
master circuit board 91 does not receive any signal from thechip 105, themotor 69 inside the lock of the present invention is immovable to unlock the lock. However, after the insertion of the key, the lock core 7 is unlocked to allow the lock core 7 to be rotatable so as to deactivate the conventional latching mechanism. In the meantime, theconductor 107 is engaged with the engagement bead 231. By way of the abuttingelement 23, the first bar 43, the first conductingbead 55, thesecond bar 61 and the conductingseat 67, the information in thechip 105 will be transmitted to themaster circuit board 91 to verify whether the inserted key is correct. The key 99, after being inserted into the lock core 7, is engaged with thefirst conductor 45. The first clutch 25 pushed by the key 99 will be moved axially so as to push thesensing element 51 to engage with thesecond conducting bead 57, as shown inFigures 5 and6 . Therefore, an electrical connection is established among thefirst conductor 45, thesensing element 51, thesecond conducting bead 57, thesecond bars 61, the conductingseat 67 and themaster circuit board 91. After verification is confirmed, themotor 69 is activated by themaster circuit board 91 and themotor 69 drives the threadedrod 71 to rotate, which in turn drives theactuator 75 and the second clutch 33 to move toward the key 99 via thenut 73. In the meantime thecavity 37 of the second clutch 33 is aligned with theextension 29 of the first clutch 25, as shown inFigure 4 . Thus rotation of the key 99 is able to rotate the lock core 7, therotor 81 is also rotated such that the boss of thecam 77 is also moved and the lock is unlocked. - When the
rotor 81 is rotated, themaster circuit board 91 is able to determine whether the lock of the present invention is in a normal operational status. That is, if only the lock core 7 is rotated but not therotor 81, themaster circuit board 91 is able to send out a signal to the buzzer to generate the alarm. An electromagnetic valve can be applied to the cylinder lock to replace themotor 69. The electromagnetic valve is connected to the second clutch 33 so as to move the second clutch 33 to move linearly. - With reference to
Figures 7-10 , another example of a design of a lock mechanism, which is not according to the present invention, is shown to have a lock body 1, a lock core 7, arotor 81, and a coupling device. The cylinder body 1 has ahollow barrel 5 and a cutout 3 dividing thebarrel 5 into two halves to receive therein acam 77 having aboss 79 formed on a bottom of thecam 77. - The lock core 7 is a hollow cylinder and has two opposed
paths 11 respectively defined in parallel to a longitudinal axis of the cylinder in a side periphery of the lock core 7, apassage 13 axially defined in the side periphery of the lock core 7 and agroove 19 defined in a proximal end of the lock core 7. Thepassage 13 is provided to receive therein apad 15 and aspring 23 that engages thepad 15. The lock core 7 further has multiple tumblers (not shown) inside the lock core 7. A firstrotation circuit board 123 is securely mounted on a distal end of the lock core 7 and has multiplesecond cutouts 125 defined in a periphery of the firstrotation circuit board 123 such that multiple screws (not shown) are able to extend through thesecond cutout 125 and into the distal end of the lock core 7 to secure the firstrotation circuit board 123. The firstrotation circuit board 123 has acontact 131 securely mounted on the firstrotation circuit board 123. - The
rotor 81 has a longitudinally defined first slit 83 and a side slit 85 defined along thefirst slit 83. Thefirst slit 83 and the side slit 85 communicate with an open end defined in a distal end of therotor 81. A second rotation circuit board 127 is securely mounted on the distal end of therotor 81 and has asecond contact 131 mounted thereon. Ahole 811 is defined in a side face of therotor 81. - The coupling device includes a
first clutch 109, asecond clutch 115, and athird clutch 133. Thesecond clutch 115 has two opposedbosses 117 each formed on an end of thesecond clutch 115 to be received in thepath 11 of the lock core 7 and aprotrusion 121 formed on a side face of thesecond clutch 31. Before the firstrotation circuit board 123 is secured to the distal end of the lock core 7, thesecond clutch 115 is first placed in a central hole 9 of the lock core 7 with the twobosses 117 received in thepath 11 and then the firstrotation circuit board 123 is mounted on the distal end of the lock core 7. Multiplefirst springs 119 are received between the firstrotation circuit board 123 and thesecond clutch 115. After thepad 15 and thespring 23 are received in thepassage 13 of the lock core 7, the lock core 7 is assembled in a front portion of one of thebarrels 5 of the body 1. Apositioning ring 233 is applied to extend the radial slit 10 and into thegroove 19 of the lock core 7 to prevent the lock core 7 from moving axially in the body 1. However, the lock core 7 is able to rotate inside the body 1. - The
first clutch 109 has an indent 113 corresponding to theprotrusion 121 of thesecond clutch 115 and two opposed first blocks 111 respectively formed on a side of the first clutch 109 to be received in thefirst slit 83 of therotor 81. - The
third clutch 133 has two second blocks 137 respectively formed on a side face of the third clutch 133 to be received in thefirst slit 83 of therotor 81 and an elongated hole 141 defined in a side of thethird clutch 133. A through hole 135 is defined in a front face of the third clutch 133 to communicate with a threadedhole 145 of aseat 143 after theseat 143 is received in the third clutch 133 from the elongated hole 141. Thereafter, a projection 147 formed with theseat 143 is extended out of the elongated hole 141. Both thethird clutch 133 and theseat 143 are received in therotor 81 with the two second blocks 135 received in thefirst slit 83. Asecond spring 139 is sandwiched between thefirst clutch 109 and thethird clutch 133. Therotor 81 further has a driving element, positioning block 153 and aconductor 149 having two opposedarms 151 respectively formed on a side of theconductor 149. The positioning block 153 has two opposed cutouts (not numbered) to securely receive therein theconductor 149 and allow the twoarms 151 to extend out of the positioning block 153. In this embodiment, the driving element is amotor 69 having a motor shaft extending through amotor bracket 155 to be threadingly connected to a threadedbolt 71 and the threadedhole 145 of the seat 141. Themotor 69, themotor bracket 155, thethird clutch 133, and theseat 143 are assembled inside therotor 81 to have the projection 147 positioned between the twoarms 151. Then the second rotation circuit board 127 is positioned in therotor 81 by screws extending through the third cutouts 129 of the second rotation circuit board 127 and into therotor 81. Abolt 163 is provided to extend through aclamping ring 161 and into thehole 811 of therotor 81 so as to position therotor 81 with theclamping ring 161. - A
ring 157 having teeth formed on an inner side of thering 157 is assembled with the body 1 via a second slit radially defined in thebarrel 5 of the body 1 to allow therotor 81 to extend through thering 157 and thecam 77 which is received in the cutout 3 of the body 1 . Screws are applied to secure thecam 77 to an outer periphery of therotor 81. Asensor 159 is mounted on the outer periphery of therotor 81 and thesensor 159 is facing the teeth of thering 157 after therotor 81 is received in thebarrel 5 of the body 1. - After the aforementioned elements are assembled inside the body 1, because the
bosses 117 of thesecond clutch 115 are received in thepath 11 of the lock core 7, there is no relative rotation between thesecond clutch 115 and the lock core 7. Thespring 23 is electrically connected to the firstrotation circuit board 123 so that the firstrotation circuit board 123 is able to receive signals from thespring 23. - The
motor 69 is able to drive the threadedbolt 71 so as to move theseat 143, which in turn drives the third clutch 133 to move. Movement of the third clutch 133 moves thefirst clutch 109 via thesecond spring 139. Because the projection 147 of theseat 143 is received in the side slit 85 of therotor 81, the movement of theseat 143 allows the projection 147 to move away from or into the side slit 85. Meanwhile the first blocks 137 and the second blocks 111 are also moved into or away from thefirst slit 83 of therotor 81. When the projection 147 is extended out of the side slit 85 and the first blocks 137 and the second blocks 111 are moved into thefirst slit 83, therotor 81 can not be rotated. However, when the first blocks 137 and the second blocks 111 are moved out of thefirst slit 83, therotor 81 can be rotated. When the rotor is rotated, theboss 79 is moved in the cutout 3 to drive a different locking device (not shown). - The lock mechanism further has an alarm system to sound an alarm when there is an unauthorized person trying to unlock the lock mechanism so as to enhance the safety of the lock mechanism. In this example, there is further provided a
rotation seat 89. Therotation seat 89 has amaster circuit board 91, abattery 93, abuzzer 95, and acover 97 provided in front of therotation seat 89. Thebattery 93, thebuzzer 95, and themaster circuit board 93 are electrically connected with one another and themaster circuit board 91 is electrically connected to the second rotation circuit board 127 and thesensor 159. - A key 99, as shown in
Figure 7 , provided with embedded circuit includes abody 101, achip 105 formed in thebody 101 and having a conductingplate 103 integrally formed on thechip 105 and an encapsulation (not shown) enclosing thechip 105 inside thebody 101 to avoid damage to thechip 105. Thecontacts 131 on the firstrotation circuit board 123 and the second rotation circuit board 127 are able to send signals to the motor and the clutch device so as to drive the lock mechanism. - When the lock mechanism is in a locked status, there will be two different locking mechanisms to provide the desired locking effect, namely the conventional latching mechanism in the lock core 7 and the coupling device. If a user is trying to unlock the lock mechanism, the user will have to unlock the lock core 7 and the clutch device of the lock mechanism sequentially, otherwise the
buzzer 95 will sound an alarm to warn the security guard that there is an illegal action going on. To be more specific of the operation of the lock mechanism, it is to be noted that before the key 99 is inserted into the lock core 7, the multiple tumblers will lock the lock core 7 to prevent the lock core 7 from rotation such that the lock mechanism is locked. Because how the tumblers lock the lock core 7 is conventional in the art, detailed description thereof is omitted for brevity. In the meantime, the firstrotation circuit board 123 and the second rotation circuit board 127 are fixed so that there is no signal transmitted to themaster circuit board 89 to drive themotor 69 to move. Thethird clutch 133 and thefirst clutch 109 are received in therotor 81 and thus the first blocks 111 of thefirst clutch 109 and the second blocks 137 of the third clutch 133 are received in thefirst slit 83 of therotor 81 to disable the rotation of therotor 81. A second locking effect is accomplished. - On the contrary, after the key 99 is inserted into the lock core 7, the tumblers are rearranged to allow the lock core 7 to be rotatable. Meanwhile the conducting
plate 103 of thechip 105 engages with thespring 23 such that code information in thechip 105 will be transmitted to the firstrotation circuit board 123 via thespring 23. Then the information is transmitted to themaster circuit board 91 via thecontacts 131 of the firstrotation circuit board 123 and the second rotation circuit board 127. After themaster circuit board 91 receives the information, themotor 69 is activated to drive the threadedbolt 71 to rotate. The rotation of the threadedbolt 71 drives thethird clutch 133 and the first clutch 109 to move toward the key 99 to allow the first blocks 137 and the second blocks 111 to be away from thefirst slit 83 and to allow engagement between thefirst clutch 109 and thesecond clutch 115, until the extension 147 of theseat 143 engages with one of thearms 151 of theconductor 149 such that themotor 69 is stopped. Therefore, rotation of the key 99 drives not only the lock core 7, but also therotor 81 and thus theboss 79 of thecam 77 is driven to unlock the lock mechanism. While therotor 81 is rotated, thesensor 159 is able to sense the teeth of thering 157 and themaster circuit board 91 will determine whether the lock mechanism is in normal unlocking condition and thus thebuzzer 95 will not sound an alarm. However, if only the lock core 7 is rotated but not therotor 81, thebuzzer 95 will then sound the alarm. Themotor 69 can be replaced by an electromagnetic valve that is connected to the third clutch 133 to drive the third clutch 133 to move linearly so as to accomplish the aforementioned objective. - Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
