From equations (1) and (2), the magnetic flux density of the two electromagnets (2071/2072) can be calculated separately and the magnitude and direction of the F suction or repulsive force can be calculated to match the weight of the lens to design the optimal driving force. Hereinafter, the lens driving device using the electromagnetic thrust according to the present embodiment will be described with reference to the related drawings. For the sake of easy understanding, the same components in the following embodiments are denoted by the same reference numerals. Please refer to FIG. 2 to FIG. 4 , which respectively show a perspective view, a cross-sectional view and a top view of a first embodiment of a lens driving device using electromagnetic thrust. In this embodiment, the first push-up mechanism is A rail groove 208, the first pushing mechanism is a combination of a fixed column 9 M343180 209. In Fig. 2, the lens driving device comprises a frame body, a barrel 202, a lens holder 203, a lens 204, and a push plate. (kicker) 205, a spring element 206 and a plurality of electromagnet parts 2071, 2072. The lens 204 is fixedly coupled to the lens holding portion 203 and moves with the lens holding portion 2〇3. The push plate 2〇5 is disposed on the outer wall of the sleeve 202 and fixed to the sleeve 202, and the electromagnet 2072 is combined with the push plate 205. The electromagnet 2071 is disposed on the frame 201, and the two ends of the elastic member 2〇6 are The push plate 205 and the frame 201 are coupled.

The lens holding portion 2〇3 has a fixing post 2〇9, and the sleeve 2〇2 has a sliding groove 208, and the track of the sliding groove 208 has an angle with the central axis direction of the sleeve 2〇2. When the lens holding portion 203 is disposed in the sleeve 2〇2, and the fixing column 2〇9 is disposed in the sliding rail groove 2G8, the lens holding portion 2G3 is in contact with the sleeve %2〇9 and the sliding groove 208.

When the electromagnet (10) is turned on (4), the positive electrode enters the electromagnet, according to the right hand of Ampere, and the electromagnet = when the electromagnet is in the end face of the electromagnet. The two electromagnets are 2〇71盥2, because the sleeve 202 can form a repulsion in the same direction as the magnetic field in the same direction, so that the tube 2Q2 = turn to the fixed column. 209 (10) When the sliding rail slot moves = _, the fixing post M343180 is also driven, and the fixing post 209 is forced to rotate upward. When the sleeve 202 is rotated to the left, the fixing post 209 is forced to rotate downward, so that the lens clamping portion 203 can be moved along The central axis direction is rotationally displaced. Since the two ends of the elastic member 206 are coupled to the push plate 2〇5 and the frame 201, when the push plate 205 is returned to the electromagnet 2071, it is also pressed to the elastic member 206 to cause the elastic member 206 to generate a restoring force, and The greater the angle of rotation of the sleeve 2〇2, the higher the degree of compression of the elastic member 206 and the greater the restoring force, until the repulsive force and the restoring force are equal, the lens holding portion 203 stops rotating. When the position of the fixing column 209 and the lens holding portion 203 shown in Fig. 5 is higher than the position shown in Fig. 2, the elastic member 206 is deformed by being pressed and deformed. When the energization of the electromagnets 2〇71 to 2〇72 is stopped, the repulsive force between the electromagnets 2071 and 2072 disappears, and the restoring force of the elastic member 2〇6 provides a spring force opposite to the above repulsive force to the push plate 205, forcing the push. The plate 2〇5 is moved away from the frame 201' so that the sleeve 2〇2 is rotated back until the elastic member 2〇6 is restored to its original shape. The lens holding portion 203 stops rotating. During the rotation of the lens holding portion 2〇3, the fixing post 209 slides down the slide rail groove 208 to return the lens holding portion 2〇3 to the position shown in Fig. 2 . Among them, the shape and length of the track groove 2〇8 and the inflammatory angle of the central axis direction of the sleeve 2〇2 can be changed as the application needs. For example, if the execution of the groove is = straight, the axial movement of the lens holding portion 2〇3 and the rotational distance of the sleeve 2〇2 are in accordance with the relationship of (8), which is the sliding groove and Set \ the angle between the mandrel directions. In the present embodiment, for the electromagnets 2071~2〇72, the current magnitude is matched with the second reading 206 and the sleeve 202 torque, and the displacement amount d of the lens holding portion 2〇3 in the middle two can be calculated, or can be experimentally Learned, as shown in Table 1: Season 11 200/100 Reverse/Shun 0.3 100/100 Shun/Shun-0.3

In this embodiment, the first pushing mechanism is a sleeve thread cutting surface 4〇1, and the second pushing mechanism is a combination of a clamping portion thread cutting surface 402. The second embodiment differs from the first embodiment in that: The cylinder 202 has a sleeve thread cutting surface 4〇1, and the lens clamping portion 2〇3 has a clamping portion thread cutting surface 402, and the sleeve thread cutting surface 4〇1 is in contact with the clamping portion thread cutting surface 4〇2, The lens clamping portion 203 and the sleeve 2〇2 are connected to each other, and the lens clamping portion 203 and the frame body 2〇1 respectively have a groove 4〇3 and a guiding device (not shown). The groove 403 is combined with the guiding device so that the lens holding portion 2〇3 cannot be rotated, but can only be displaced along the central axis direction of the sleeve 202, as shown in Fig. 8. Fig. 8 is a view showing a state in which the lens driving device is not energized when the electromagnets 2071 to 2072 are not energized. When the electromagnets 2071 to 2072 are energized to generate a repulsive force between the electromagnets 2071 to 2072, the repulsive force forces the push plate 205 away from the electromagnet 2071, and the sleeve 2〇2 is rotated. As shown in Fig. 9, when the sleeve 202 is rotated, the threaded face of the sleeve pushes the thread cutting plane 402 of the clamping portion, thereby driving the lens holding portion 2〇3 upward by a displacement amount d. In this embodiment, the elastic member 206 is coupled between the sleeve 2〇2 and the frame body 2〇1 (not shown in FIGS. 7 to 9), and when the electromagnets 2〇71~2〇72 are stopped, the power is turned on. When the repulsive force disappears, the restoring force of the elastic member 206 forces the sleeve 2〇2 to rotate, whereby the holding portion 203 returns to the original state, as shown in FIG. 12 M343180, please refer to the figure 第) and the η diagram, which respectively show a three-dimensional combination diagram and an actuation diagram of the second embodiment of the lens driving of the present invention. In this embodiment, the first embodiment is a The first thread (the male thread is used in this embodiment) is disposed inside the sleeve, and the second pushing mechanism is a second thread (the female thread is used in this embodiment) is disposed on the outer wall of the lens portion. The second embodiment is different from the above embodiment in that the outer portion of the lens holding portion 2 has a male thread 602, and the inner side of the sleeve 202 has a female thread (the wide lens holding portion 203 is not shown in the figure. The barrel 202 is engaged with the female thread by the male thread 6〇2 and is engaged with the sleeve 202. The lens holding portion 2〇3 and the frame body 2〇 respectively have a groove 6〇1 and a guide. The device (not shown in the figure), because the groove and the guiding device are combined, the lens holding portion 2〇3 cannot be rotated, but only along the center of the sleeve 2 () 2 (the same axis of the lens) Directional displacement. Fig. 10 shows the state in which the lens driving device is not energized when the electric power is 2071~2072. When the electromagnets 2071~2072 are connected with currents in different directions as described above, a repulsive force is generated between the electromagnets 071 2072' This repulsive force forces the push plate away from the electromagnet 2071' and then moves the tether 202. Since the groove 6〇1 is combined with the guiding device on the frame 2〇1, the lens holding portion 2〇3 can only extend over the sleeve. The central axis of the barrel 2〇2 moves and cannot rotate, so when the sleeve 2〇2 rotates, the female thread pushes the male thread 6〇2, When the lens holding portion 2〇3 is moved upward, as shown in Fig. u, the male thread is exposed due to the slight movement of the lens holding portion 203. In the present embodiment, the elastic member 2〇6 is connected.

The push-up mechanism is a slot 208, and the red push-up mechanism is a fixed pillar. In the second embodiment, the jaw mechanism is a sleeve thread cut surface 4G1' and the second push-up mechanism is a run-off pattern. Two tired [text cut surface 402, in the third embodiment, the first push-up mechanism is a first screw, also caress the screw 602) "the first push-up mechanism is a second thread (such as Thread). The upper piece ·= 丨 is only an example 'but not limited to this, any rotation of the county can drive the lens clamping _ mechanism is within the scope of this creation. In addition, the above two examples The electromagnet period ~ energization produces a repulsive force for the operation of the green axis, but it is limited to the limit. Wherever, the electromagnetic field generated by a plurality of electromagnetic Weidians is generated by the direction of the electromagnetic field between each other. Repulsive force or suction force, and the restoring force of the elastic member to rotate the sleeve back and forth, and further, the lens driving device σ is moved between the first position and the second position, and the lens driving device is white within the protection range of the present invention. In the above description of the embodiment, the second figure is the secret of the lens continuation at the first position, and (4) the __ lens holder is at the position _. Fig. 8 shows the state in which the lens holding portion is in the _ position, and M shows the state in which the lens holding portion is at the second position, and the tenth image shows the state in which the lens is in the first position, and The figure shows the state of the lens holding portion in the second position. The loyalty and electricity? The electromagnet core of the iron 2〇71~2〇72 can be made of soft magnetic material (S〇ftmagnet), which is characterized by easy magnetization and easy demagnetization, which is very easy in the M343180 after the electromagnet is energized. Being magnetized, the magnetic lines of force can be concentrated on the end face of the electromagnet, but when the electromagnet is not energized, the magnetic force of the electromagnet core is also entangled, that is, the soft magnetic material itself has no ability to maintain magnetization; and the main component of the soft magnetic material can be high-purity iron. (Raw iron, soft iron), steel with very low carbon content, niobium steel, iron-nickel alloy (Fe_Ni A11〇y or Permali〇ys), magnesium-zinc alloy (Mg-Zn alloy), scale alloy called aU〇y) , ruthless alloy (Mn Zn.y), or metallic glass (metame glas turn, can withstand high temperature, ...
