As shown in FIG. 1 to FIG. 3 and FIG. 8 to FIG. 10, the electronically controlled lock is created after being opened to the door panel 8 of the right door, wherein the wheel 26 is in an unlocked state as shown in FIG. The second touch portion 2622 is located at a position where the second micro switch 272 is not touched (the purpose of not pressing is mainly to inform the control device 27 that the control device 27 is currently in an unlocked state, and the control device 27 repeats the operation to perform the unlocking operation. , an error warning is generated), at this time, the hollow portion 2522 of the transmission wheel 25 is aligned with the rubber 263 of the rotating wheel 26; when the user operates the operating element 23 or the lock group 41 to perform locking by manual operation, only To rotate the operating element 23, the rotating wheel 26 can be directly driven to rotate counterclockwise (such as arrow A). Since the operating element 23, the driving rod 411 and the rotating wheel 26 are interlocked together, the driving rod 411 can be driven. The latch 6 moves the latch 6 to a locked state (as shown in FIG. 10), and the second touch portion 2622 of the runner 26 is located at a position to touch the second micro switch 272 (the purpose of the touch is mainly to inform The control device 27 is currently in a locked state, and the control device 27 repeats the operation. Do locking action, will produce an error warning), the runner 26 will move from the unlocked state to the locked state of FIG. 8 to FIG. 10. By the same token, if the runner 26 is to be manually moved to the unlocked state, the operating member 23 can be rotated in the opposite direction. Of course, the lock set 41 also has the same function as the operating member 23, This will not be repeated here.

As shown in FIG. 1 to FIG. 7, when the electronically controlled lock is already installed in the door panel 8 of the right door, the wheel 26 is electronically operated to be rotated from the unlocked state of FIG. 8 to the locked state of FIG. The control unit 27 transmits a latching signal, and the second touch portion 2622 of the wheel 26 is located at a position where the second micro switch 272 is not touched. The motor 24 is driven to rotate the turbine 241, and the gear 251 of the transmission wheel 25 is driven by the turbine 241 to rotate the friction wheel 252 of the transmission wheel 25, and the rotating wheel 26 is aligned from the hollow portion 2522 of the friction wheel 252. At this time, the control device 27 detects that the motor 24 is running at a low current, and then rotates until the contact portion 2521 contacts the rubber 263 of the runner 26 (see FIG. 9). Due to the frictional force, the runner 26 is rotated. When the friction wheel 252 is rotated, when the friction wheel 252 rotates back to the wheel 256 when the hollow portion 2522 is aligned with the wheel 26, the control device 27 detects that the motor 24 is running at a low current. When the height is higher and then lower, the motor 24 and the transmission wheel 25 stop rotating, and the latch 6 reaches The locked position (as shown in FIG. 10), if the rotating wheel 26 is rotated by the operating member 23, since the rotating wheel 26 is not in contact with the driving wheel 25, the rotating wheel 26 is easily rotated; wherein the friction The outer circumferential arc length of the contact portion 2521 of the wheel 252 is approximately equivalent to the arc length corresponding to the outer circumference of the 110 degree of the runner 26. Therefore, the friction wheel 252 rotates once, and the wheel 26 rotates about 110 degrees, and the operating element 23 also rotates 110 degrees (because the transmission rod 411 and the gap of the cross hole 3022 of the adapter), that is, The latch 6 is in an unlocked state to a locked state. When the wheel 26 is rotated counterclockwise (as shown in FIG. 8 and the direction of the arrow A), in the unlocked state, the first touch portion 2621 of the cam 262 is not touched. An inductive switch 271, when the reel 26 is driven for a period of time, the first touch portion 2621 of the cam 262 touches the first inductive switch 271 (as shown in FIG. 9), which indicates that the latch 6 is not correctly extended. And when the revolver 26 continues to rotate, the first touch portion 2621 of the cam 262 does not touch the first inductive switch 271 (as shown in FIG. 10), that is, the latch 6 is correctly extended, wherein the The latch 6 is moved to the locked state (as shown in FIG. 10), and the second touch portion 2622 of the runner 26 is located at a position touching the second micro switch 272, and the motor 24 is informed that the next time the motor is to be rotated, the present The creation of the first inductive switch 271 can be omitted.

As shown in FIG. 1 to FIG. 7, when the electronic lock of the present invention has been installed after the right door is opened, the wheel 26 is electronically operated to be rotated from the locked state of FIG. 10 to the unlocked state of FIG. a correct authentication signal to the control device 27, the control device 27 transmits an unlock signal, thereby driving the motor 24 to rotate the turbine 241, and the gear 251 of the transmission wheel 25 is driven by the turbine 241 to make the transmission wheel 25 The friction wheel 252 rotates, and the rotating wheel 26 is aligned from the hollow portion 2522 of the friction wheel 252. At this time, the control device 27 detects that the motor 24 is running at a low current, and rotates to the contact portion 2521 to contact the wheel. When the rubber 263 of 26 (see FIG. 9), the runner 26 is driven by the friction wheel 252 due to the frictional force, and when the friction wheel 252 rotates one turn back to the hollow portion 2522 to align the runner 26 Since the control device 27 detects that the running current of the motor 24 changes from low to high and then goes low, the motor 24 and the transmission wheel 25 stop rotating, and the latch 6 reaches the unlocked position (as shown in FIG. 8). At this time, if the runner 26 is rotated by the operating member 23, since the runner 26 and the transmission wheel 25 are not There is contact, so the wheel 26 is easily rotated, wherein the outer circumference arc length of the contact portion 2521 of the friction wheel 252 is approximately equivalent to the arc length corresponding to the outer circumference of the 110 degree of the wheel 26. Therefore, the friction wheel 252 rotates once, and the wheel 26 rotates about 110 degrees, and the operating element 23 also rotates 110 degrees (because the transmission rod 411 and the gap of the cross hole 3022 of the adapter), that is, The latch 6 is in a locked state to an unlocked state. When the wheel 26 rotates clockwise (as shown in FIG. 10 and the direction of the arrow B), in the locked state, the first touch portion 2621 of the cam 262 is not touched. An inductive switch 271, when the reel 26 is driven for a period of time, the first touch portion 2621 of the cam 262 touches the first inductive switch 271 (as shown in FIG. 9), which indicates that the latch 6 is not properly retracted. When the reel 26 continues to rotate, the first touch portion 2621 of the cam 262 does not touch the first inductive switch 271 (as shown in FIG. 8), that is, the latch 6 is correctly retracted, wherein the The latch 6 is moved to the unlocked state (as shown in FIG. 8), and the second touch portion 2622 of the wheel 26 is located at a position where the second micro switch 272 is not touched, and the motor 24 is informed that it is to be reversed next time.

As shown in FIG. 1 to FIG. 3 and FIG. 11 to FIG. 13 , the electronic control lock is only required to adjust the direction of the operating element 23 by about 90 degrees counterclockwise when mounted on the left door panel 8 . The transmission rod 411 of the outer lock body 4 is horizontally mounted on the adapter 30b, wherein the latch 6 is in an unlocked state as shown in FIG. 11, and the latch 6 is partially extended. 13 shows that the latch 6 is in a locked state, and the manual and electronic operation modes are substantially the same as those described above, and are not described herein.

As shown in FIG. 9, when the latch 6 is in the partially extended state, a sudden failure occurs, since the rubber 263 of the runner 26 and the friction wheel 252 of the transmission wheel 25 are driven by friction, and the The transmission wheel 25 meshes with the turbine 241 of the motor 24, so that the transmission wheel 25 cannot be rotated. At this time, only the operating member 23 is rotated, and the rotating wheel 26 is rotated relative to the friction wheel 252 of the transmission wheel 25, that is, The wheel 26 and the latch 6 can be moved to an unlocked position.
