As shown in the first and second figures, the mirror actuator 本 of the present invention includes a base 10, a hollow magnetic component 12, and a lens carrier assembly Μ. At the same time, the hollow magnetic component 12 includes a first hollow magnet 120, a hollow magnetic conductor = 122, and a second hollow magnet 124. Wherein, the _ 导 magnetic sheet (2) has a - first bonding surface (not shown) and a second bonding surface (not labeled), and the first bonding surface is magnetically coupled to the first hollow magnet 12 〇, and the second bonding surface is magnetically bonded In ^ hollow magnet 124. Further, the first hollow magnet m and the second hollow magnet 124 are magnetically coupled to the hollow magnetic conductive sheet 122 with the same polarity. Refer to the first and second figures. The hollow magnetic component 12 is fixed to the base ίο to form a non-movable component. At the same time, the magnetically permeable member 142 is disposed at the inner edge of the hollow coil 144, and is fixedly disposed on the recess 1400 of the lens holder 140374 with the hollow coil 144 to constitute a lens carrier assembly 14. As such, the lens carrier assembly 14 is a movable component. At the same time, the entire lens carrier assembly 14 is disposed at the inner edge of the hollow magnetic component 12 and is spaced from the hollow magnetic component by a slidable gap (not labeled). At the same time, the lens carrier 14 is provided with a lens (not shown) for image focusing. Refer to the first and second figures. The first hollow magnet 12〇 and the second hollow magnet 124 are magnetically coupled to the hollow magnetic conductive sheet 122 with the same polarity, and the hollow magnetic conductive sheet 122 accommodates the magnetic lines of force condensed by the first hollow magnet 12〇 and the second hollow magnet I%. And guiding the magnetic lines of force through the hollow coil 144 and the magnetic conductive element 142 to respectively form a first magnetic line circuit ¢1 and a second magnetic line circuit Φ2. The first magnetic field line φ ΐ and the second magnetic field line 12 are in common with the electromagnetic _ interaction generated by the energization of the hollow coil 144 to generate an electromagnetic thrust to actuate the lens carrier assembly 14 to displace. Since the first hollow magnet 12〇 and the second hollow magnet m are magnetically polarized with the same polarity and are combined with the hollow magnetic conductive sheet 122, the emitted first magnetic line loop φ 1 and the second magnetic line loop Φ2 form a repulsive action, instead of The first magnetic field line Φ1 and the second magnetic line circuit 12 are accommodated by the hollow magnetic conductive sheet 122. The first magnetic line circuit Φ1 and the second magnetic line circuit φ 2 are respectively diverge from the first hollow magnet 12〇iN pole and the second hollow magnet 124, respectively, and are guided by the hollow magnetic conductive sheet 122, and are turned to the slidable gap.

As shown in the third figure, the Α to D curve indicates the state of the lens and the state of the force of the lens when the hollow coil 144 is not energized. The B to C curve indicates the state of the lens and the state of the force of the hollow coil 144 under the forward current. The F to E curve shows the state of the lens and the state of the force with the hollow coil 144 under the reverse current. Refer to the third figure. The lens carrier assembly 14 is initially parked in the first position L1. Thus, in the unenergized state, the hollow coil 144 is subjected to a force state at point A, and the lens carrier assembly 14 is subjected to a reverse first holding force generated by a magnetic conductive element 与] and a magnetic line circuit. Maintain at the first position L1. If the first position L1 is to be changed to the second position L2, the hollow coil 144 is turned on and forward current, and the state of the hollow coil 144 and the magnetic conductive element I42 is changed to B, point, at this time, the lens holder assembly The side 'which is subjected to the forward electromagnetic thrust will begin to shift the second position u, and the state of the force of the hollow coil 144 and the magnetic conductive element 142 will move from point B to point c. When the forward current that is passed into the shirt coil 144 is released, the hollow coil 144 is guided by the magnetic element == will be changed from point C to point D. At this time, the lens carrier assembly is plunged to the day - the magnetically ploughed M2 and the second The positive second holding force generated by the magnetic line circuit (10) acts to maintain it in the second position L2. Re-examination of the exam - the purpose. Want Lin Erjian £2 change to hollow coil 144 pass reverse f, 彳 _ 144 and magnetically conductive element two h' text more E point 'At this time 'lens carrier assembly 14 under the role of reverse electromagnetic thrust' will start Move to the first position U, and the hollow wire 11 201037448 circle 144 and the magnetically permeable element 142 will move from point E to point? point. Then, after the reverse current flowing into the hollow coil 144 is released, the force applied to the hollow coil 144 and the magnetic conductive member 142 will be changed from point F to point a. At this time, the lens holder assembly 14 is subjected to a magnetic conductive member 142 and The reverse first holding force generated by a magnetic line loop Φ1 is maintained to maintain the first position u. Thus, in the case where the hollow coil 144 is not energized, the lens holder assembly Μ is affected by the reverse first retaining force and the positive second retaining force, and remains at the first position L1 and the second position u. Moreover, by controlling the forward current and the reverse current of the hollow coil 144, and the positive and reverse electromagnetic thrust generated by the magnetic conductive element, the brigade carrier surface member 14 can be arbitrarily removed at the first position U or the second position. On L2, to achieve the purpose of two-stage lens actuation. The lens actuating device of the present invention can be used as a two-stage lens actuating system to make the lens act on the two fields, and the retention of the magnetic mirror is the magnetic resonance. When the coil is energized, it will generate a magnetic field with the magnet and detect the shovel. The electromagnetic thrust can make the lens overcome the holding force of the position. The head will be exposed to the other position and the coil will be energized and then mirrored. The principle of this action is that the square dog = holding force to keep it in another position. Continuously pulling the pull type does not need to continuously energize the coil, but can hold the lens, keep it at the position of the target, and save power. When the thrust is made of H11 phase (four) current, the lens will be subjected to the reverse electromagnetic head and will be energized after the coil is energized on the mirror. The above = two holdings in the original position to achieve power saving effect. ‘,... see the master-slave actuation, and can be 12 201037448 vacant magnetic _ magnetically conductive components and have the following advantages. y, the slave displacement mode actuates the lens, the piece, to increase the electric power of the hollow coil when it is energized = the magnetic flux at the inner edge of the hollow coil to the positioning. 2. The present invention in the hollow line 'and then allows the lens to quickly move the magnetic field between the magnetic components, the hunting by the magnetic components and the middle to reach _, electricity _.
