It is worth mentioning that the motor 35 1 will continue to drive the power wheel 353 and the first gear 41 due to the inertia at the moment when it stops rotating. Therefore, the inertia of the motor 351 can make the first gear 41 shorter. The engaging surface 412 is completely disengaged from the long engaging surface 422 of the second gear 42 so that the hand control 34 can be freely controlled manually. For the same reason, when the user wants to switch the electric lock 3 from the locked position in the sixth figure to the unlocked position in the fourth figure in an electronically controlled manner, the motor 351 is also driven by a remote controller not shown in the figure. When the 3 position is locked in the 10 locked position, the sensor 51 is in contact with the off sensor switch 53 and the motor 351 is reversed to drive the power wheel 353 and the first gear 41 to rotate counterclockwise. When a gear 41 rotates counterclockwise, its short meshing surface 412 will also mesh with the long meshing surface 422 of the second gear 42 again, and thus the second gear 42, the hand control 34, and the sensing element Η 15 will be engaged with each other. Clockwise rotation for unlocking action. When the sensing element 51 touches the open sensing switch 52, the hand control 34 also returns to the unlocked position, and the short meshing surface 412 of the first gear 41 is inertia and long by the motor 351. The engaging surface 々a is disengaged, so that the hand control 34 is restored to a mode that can be manually controlled. Referring to the seventh figure, in the present invention, when the first gear 41 and the second gear are in the M-unsettled state, the hand control 34 can be freely operated by hand control. When the hand control 34 is manually controlled to switch to the locked position, Since the sensing = 51 will touch the sensing switch 53 as the hand control 34 rotates. Under this condition, if the user unlocks with the remote control, the motor 351 will be counterclockwise as shown in the seventh figure and the arrow. Rotate, although the first gear 41 will be empty 11 1220912 during the rotation, the description of the invention (8) rotates about 270 degrees and then meshes with the second gear 42, but the first gear 41 will not drive the sensing unit when idling 5 and hand control 34, therefore, this idling operation will not produce any power transmission. When the hand control 34 is switched to the unlocked position, the motor 351 will stop rotating and resume due to the on-sensing switch 52 being pressed. Go to the state of the fourth figure. Referring to the eighth figure, the general structure of the second preferred embodiment of the electric lock 3 of the present invention is the same as that of the first embodiment, except that the first gear 41 is integrally formed on the power wheel. 353. See Ninth The structure of the third preferred embodiment of the electric lock of the present invention is also substantially the same as the first embodiment. The difference is that the sensing element 51 of the sensing unit 5 is integrally formed on the second gear 42 in two rings. One of the end faces 421. The sensing switches 52 and 53 are moved toward the radially inner end of the second gear 42 to correspond to the sensing member 51. The change in the aforementioned structure can also achieve the expectation. Referring to the tenth figure, the general structure of the fourth preferred embodiment of the present invention is also the same as that of the first embodiment, except that the first gear 41 is provided with two adjacent short-minging surfaces 412 and is formed by them. Two cross-sections 413 and 414 extending from one cool-combining surface 411 to the other clamping surface 412. One of the openings 415 and 416 of the cross-sections 4i3 and 414 respectively faces the two clamping surfaces 411 of the first gear 41. The force that imparts to the radial inner end of the short spraying surface 412 of the first gear 41 is displaced. When the electric mechanism 35 encounters insufficient power of the battery unit 354 during driving, the first gear 41 and the second gear 42 are in Whispering L 'At this time, the user can manually control the mode rotation and the second tooth U Spraying hand control 34, when the second gear 42 rotates, the __gear 41 12 1220912 玖, the short meshing surface 412 of the invention description (9) can be moved radially inward by the slits 413, 414, The second gear 42 can be smoothly rotated with the hand control 34 to achieve the purpose of manual operation in an emergency. 10 Referring to the eleventh and twelfth figures, the structure of the fifth embodiment of the electric lock of the present invention is also substantially the same as The first embodiment is different in that the power wheel 353 has two limit posts 357 and a protruding post 358, and the first gear 41 is provided with two long slot holes for the middle-support limit post 357 to protrude. 417, and-the positioning grooves 418 corresponding to the protrusions 358, on the two left and right spaced groove walls of the positioning grooves 418, respectively, a resilient piece 419 protruding against the protrusions 358 is projected toward the center. The clutch unit 4 further includes two screws 43 that are cut on the limit posts to prevent the first gear 41 from separating from the power wheel 353. In the embodiment, when the power is insufficient during the use process, so that the first and second gears 41 and 42 are still in the meshing state, the user can also manually rotate the 15 inclined control 34 and the linked second gear 42. When the two gears M rotate, the first gear 41 that is meshed with the ° is hybrid; ^ you a + 铷 41 will be shifted radially inward, so that the second gear =--the teeth are crossed 'At this time the first gear 41 The two elastic fins 419 on the upper side will accumulate the resetting force for the purpose of connection. Stomach "Manual operation 20 can be controlled in emergency." "You can know that the present invention uses two gears 4 and 42 to move the electric mechanism 35 and the hand control 34, and the two gears 41 and 42 can be set to engage or separate. The short and long beveling surfaces 412 and 422, of which the tooth length between the two teethers 412 and 422 are combined with a + + hand dagger 34 that is required between the two positions. Not only is the electric lock not found in the known electric lock, this piece of simplified clutch mechanism t can be recognized as more T parts, making the installation of the electric lock easier, 13 1220912, description of the invention, (10) It is low-cost, and because the two gears 41 and 42 are separated from each other in a feeding state, the power transmission has no elastic load, that is, the power is directly transmitted by the second gear 42 that benefits from the elastic load. Therefore, the electric lock 3 of the present invention is electrically operated. It also has low load and power saving effect in the control mode. 5 The ones described above are only the preferred embodiments of the present invention. When the scope of the present invention cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the patent application and the contents of the invention specification , All should still fall within the scope of the invention patent.
