【先前技術】 隨著科技發達與消費者之需求，各式各樣的資訊產品 也隨之問世。現今電子產業之發展，個人周邊電子產品也 逐漸走向輕薄好攜帶而且功能更具多樣化，其中相機為各 類產品中具有代表性。為因應一般使用者攜帶之便利，更 亦可與手機或PDA等3C產品做結合。 二方邳機冩具備鏡頭組及龐大的機身才能達到攝影 之功能。其中該鏡頭組部分是影響成像品質關鍵之一。該

然而’習用之電磁制動之鏡頭1，由於其線圈13、14 係環繞該鏡頭1之外圍，所以會有下列缺點：第一，其磁 力線係集中在該鏡頭1之軸心中心位置，導致永久磁鐵 12所在的位置其磁力線反而較不密集，如此將造成線圈 13、14所產生之磁力線大部分無法作用而造成效能偏 低，進而更導致鏡頭1移動的效率偏低與耗電量更高之加 成效應；第二，由於該永久磁鐵12與線圈13、14是套設

products have also come out. With the development of the electronics industry today, personal peripheral electronic products are gradually becoming lighter, more portable, and more diverse in function. Among them, cameras are representative of various products. In order to meet the convenience of ordinary users, it can also be combined with 3C products such as mobile phones or PDAs. The two-way machine has a lens group and a large body to achieve the function of photography. Among them, the lens group is one of the key factors affecting imaging quality. In addition to adjusting the amount of human light, the lens group also adjusts the zoom of the subject by adjusting the zoom of the lens (adjusting or reducing the subject) or adjusting the sharpness or blurring of the subject. Previously ====== M3 03 3 94 Intent. The conventional electromagnetic brake lens device includes an annular permanent magnet, a 12-coil group 13, and a second coil group $. The annular permanent magnet 12 is coupled to the lens 1 and has a first polarity 15 and a second polarity 16 on the side. The first two: n and the second coil group 14 respectively surround the front and rear sides of the body u of the lens unit and correspond to the first polarity 15 and the second polarity 16. When the lens 1 is to be moved, the first coil group 13 and the first coil group 14 are connected to each other, so that the two coil groups I) and μ generate magnetic lines of force in a specific direction (that is, in the axial direction of the lens 1). The annular permanent magnet 12 can be provided with a force moving to the left or to the right along the axis of the lens 1. Thus, the lens 1 is pushed to move in a predetermined direction to change the position of the lens 1. . However, the conventional electromagnetic brake lens 1 has the following disadvantages because its coils 13, 14 surround the periphery of the lens 1. First, the magnetic lines of force are concentrated at the center of the axis of the lens 1, resulting in permanent magnets. At the position of 12, the magnetic lines of force are less dense, which will cause most of the magnetic lines generated by the coils 13, 14 to be ineffective, resulting in low efficiency, and thus the efficiency of the lens 1 is lower and the power consumption is higher. Secondly, since the permanent magnet 12 and the coils 13, 14 are sleeved outside the outer diameter of the lens 1, the radial size of the conventional electromagnetic brake lens device will be equal to the diameter D of the lens 1 plus the coil 13 , Μ (or permanent magnet 12, depending on which outer diameter is larger), the extra size 2Ad, and finally, the thickness of the carrier 17 (outer casing). As a result, the overall structure will be increased in size, which is contrary to the trend of thin and light design. M303394 Therefore, how to improve the electromagnetic brake device to reduce the overall volume and reduce its power consumption ‘and does not affect the precision of the control head is the current goal of the industry. [New content] The main purpose of this creation is to provide an electromagnetic brake micro lens device which can have a more compact size, higher electromagnetic drive efficiency, and lower power consumption. Another object of the present invention is to provide a magnetizing structure for an electromagnetic brake microlens device, which can be guided by a unique configuration of a magnetic structure of a unique axially wound coil and a relative position between the permanent magnet and the permanent magnet. The magnet structure and the permanent magnet are respectively located at the four diagonal corners of the lens sleeve, thereby greatly reducing the overall volume of the lens device. For the purpose of the present invention, the preferred embodiment of the electromagnetic brake microlens device of the present invention comprises: a sleeve, two permanent magnets disposed on the surface of the sleeve, and a plurality of coils wound thereon. Two magnets. The two permanent magnets are driven by the magnetic force of the two guiding magnets to perform an axial movement to change the position of the sleeve. The lying magnetic age and the two permanent magnets are respectively located at four diagonal corners of the sleeve, and each of the guiding magnets has an axial extension and is wound around a central portion of the coil, and is horizontal from both ends of the central portion. The ring extends to an extension corresponding to the ends of the two permanent magnets. Since the coil of the present invention is axially wound on the central portion of the magnetizer, the two magnets and the two permanent magnets are respectively located at four opposite corners of the sleeve and the extension of the magnetizer The system extends to the end of the permanent magnet and 7 M303394 can effectively concentrate the magnetic lines of force. Therefore, the electromagnetic brake micro lens device of the present invention can be made lighter and thinner, and the electromagnetic driving efficiency can be further increased by two.

In other words, both ends of the first central portion 221 in the axial direction slightly protrude from the front and rear edges of the sleeve 21, and the first metal coil group 222 is wound with a plurality of coils in the axial direction. The outer side of the central portion 221. The first extending portion 223 extends from the upper end of the first central portion 4221 and extends horizontally along the upper edge of the outer diameter of the sleeve 21 (so the first extending portion 223 is It is perpendicular to the first central portion 221, and corresponds to the upper end magnetic pole of the first permanent magnet 211 up to the vicinity of the upper portion of the first permanent magnet 211. The second extending portion 224 is formed by the first central portion Starting from the lower end of 221, the lower edge of the outer diameter of the sleeve 21 is horizontally ring-shaped Extending out (so the second extension portion 224 is perpendicular to the first central portion 221) until the lower portion of the second permanent magnet 212 is adjacent to the lower end of the second permanent magnet 212. The first extension The portion 223 and the second extending portion 224 extend in a direction opposite to the left and right. When the first metal coil group 222 is applied with a predetermined current, the first magnetizer 22 can be made to generate a magnetic force, and by the first The extension portion 223 and the second extension portion 224 guide the magnetic lines of force to the two ends thereof, and the points 9 M3 03 3 94 do not generate thrust corresponding to the first permanent magnet 211 and the second permanent magnet 212, thereby driving the two permanent magnets 211, 212. A linear axial Ma motion is performed along with the sleeve 21. The second magnetizer 23 further includes a second central portion 231, a second metal coil assembly 232, a third extension portion 233, and a fourth extension portion 234. Since the structure of the second magnetizer 23 is substantially the same as that of the first magnetizer 22, the second middle portion 23 of the second magnetizer 23 includes the second metal coil group 232, the third extension portion 233, and the The four extension portions 234' are not described in detail in the structure, the installation position, the actuation mode, the 22^ metal coil group 222, the first extension portion 223, and the second extension portion 224, respectively. The only end portion of the second extension magnet 233 that is worth mentioning is that the end portion extends to the vicinity of the second permanent magnet 212, while the end of the fourth extension portion 234 extends to the lower portion of the first permanent magnet 211. Nearby. As shown in Figure 3 (shown as 'the carrier 24 (outer casing), which has a hollow structure with open ends, and is sleeved outside the sleeve 2 in the preferred embodiment, the carrier 24 is A relative displacement lion for accommodating and positioning the aforementioned sleeve 21, magnetizers 22, 23, etc., and allowing it to be controlled within a limited range. (4) The specific structure of the contact 24 is not the creation The main technical features and the self-study technology can be selected, so in the present example, only the hollow cube is used for illustration. As shown in Fig. 2c and Fig. 3C, the carrier 24 of the cube includes a bit in the The four sides of the four corners are at the corners of the two sides, Μ3, Μ4, and the four sides of the M303394 are included in the space formed by the adjacent sides of the carrier 24. One of the technical features of the present invention is that the positions of the first permanent magnet 211 and the second permanent magnet 212 are respectively located at the corners of the first side angle 241 and the third side angle 243 of the diagonal corners. a first central portion 221 of the first conductive magnet 22 and a second second conductive portion 23 The central portion 231 is located at a corner of the second side angle 242 and the fourth side angle 244 of the diagonal corners respectively. The two permanent magnets 211, 212 and the central portions 221, 231 of the two magnets 22, 23 of the present invention. The positions are located at the four side corners 241, 242, 243, 244 of the four diagonal corners of the carrier 24, so the size of the permanent magnets 211, 212 does not cause the outer diameter of the electromagnetic brake micro lens device at all. In other words, the inner diameter of the carrier 24 used in the present invention is substantially equal to the size of the outer diameter D of the sleeve 21, as shown in FIG. The carrier size of the conventional technology (D+2Ad), the structure of the unique axial winding coils 222, 232 of the present invention, and the structure of the magnets 22, 23, and the permanent magnets 211, 212 are respectively located in the lens sleeve 21 The unique configuration of the corners can significantly reduce the overall size of the lens device. Please refer to FIG. 4A and FIG. 4B, which are respectively a first preferred embodiment of the artificial electromagnetic brake micro lens device. Acting in a first place In the embodiment shown in FIG. 4A and FIG. 4B, the first permanent magnet 211 and the second permanent magnet 212 are disposed on the sleeve 21 with opposite polarities. As shown in FIG. 4A, when the first metal coil group 222 M303394 and the second metal coil group 232 are connected with opposite currents, the first extension portion 223 and the fourth extension portion 234 may form an N pole. The second extension portion 224 and the second extension portion 233 form an S pole. The n poles formed by the first extension portion 223 and the fourth extension portion 234 are respectively opposite to the upper and lower poles of the first permanent magnet 211 (N, S poles). The thrust of the repulsion is generated. At the same time, the 8 poles formed by the second extension portion 224 and the third extension portion 233 are the same as the upper and lower poles (s, N poles) of the second permanent magnet 212. Therefore, the two permanent magnets 211, 212 will be pushed downward. On the contrary, as shown in FIG. 4B, when the current supplied by g is reversed, the S pole formed by the first extending portion 223 and the fourth extending portion 234 will suck up the first permanent magnet 2丨. The thrust of the repulsive force, at the same time, the N pole formed by the second extending portion 224 and the third extending portion 233 also generates a pushing force for the second permanent magnet 212 to attract the repulsion, and the permanent magnet 21 212 is displaced upward. Thus, by controlling the direction of the current to influence the direction of gravity generated by the electromagnetic actuation, the permanent magnets 211, 212 are brought together with the sleeve 21 to achieve linear axial motion Ma. Referring to FIG. 5, it is a schematic perspective view of a second preferred embodiment of the present invention. As shown in FIG. 5, in the second preferred embodiment, the present invention can provide the electromagnetic surface micro-mirror position __rotating axial motion Mr' can transform the short-distance axial displacement into a longer distance. The rotational displacement motion increases the precision of the axial displacement. In the second preferred embodiment, the carrier 24 is used for a cylinder for convenience of explanation, and two oblique guide grooves 245 extending in a spiral shape are provided on the periphery of the carrier 24. The first 12 M303394 permanent magnets 2ΐι and the first permanent magnets are obliquely disposed on both sides of the sleeve 21, and are respectively disposed on the two oblique guide grooves. After the current is driven by the coils 222 and 232 on the two magnets 22 and 23, the first permanent magnet 211 and the second permanent magnet 212 are guided by the oblique guide groove 245 to perform a displacement mode. . Since the sleeve 21 is subjected to the helical axial movement Mr, the linear axial displacement amount thereof is made smaller, so that the linear axial displacement amount can be more precisely controlled. Please refer to the 6A Marriage Six, which is a schematic diagram of the three-dimensional structure of the third embodiment of the creation of the micro-assembly device, and a schematic view of the top view. In the third preferred embodiment shown in FIG. 6A and FIG. 6B, the structure, the installation position, and the like of the sleeve 2, the first permanent magnet 21, the second permanent magnet 212, and the carrier 24 are All of the foregoing embodiments have been described in detail, so no further details are provided herein. The third preferred embodiment is different in that the magnetic conductive portion 31 further includes a central portion 311, a metal coil group 312, a first extending portion 313, and a second extending portion 314. The group 312 is wound around the central portion 31]. In addition, the first extension portion 313' extends from the upper portion of the central portion of the vertical extension to the left and right sides of the sleeve/^21 to the left and right sides, respectively, to the first permanent magnet 211 and the second permanent The magnet 212 is near the upper side and is perpendicular to the central portion 311. The second extending portion 314 extends from the lower ends of the central portion 311 to the left and right sides along the lower edge of the sleeve 21 to the vicinity of the lower side of the first permanent magnet 211 and the second permanent magnet 212, and 13 M3 03 3 94 is perpendicular to the central section 311 of the order. The overall shape of the magnetizer 31 is like the Chinese word "work". Referring to FIG. 7A and FIG. 7B, which are respectively a third preferred embodiment of the artificial electromagnetic brake microlens device, the planar development of the embodiment is performed when operating in a first position and a second position. . As shown in Fig. 7A and Fig. 7B, the first permanent magnet 211 and the second permanent magnet 212 have the same polarity at both ends and are disposed on both sides of the sleeve 21. The first permanent magnet 211 and the second permanent magnet 212 can be magnetized by two poles or bonded to each other, thereby achieving the same polarity at both ends. As shown in FIG. 7A, when the metal coil group 312 is driven by current, the left and right ends of the first extension portion 313 and the left and right ends of the second extension 314 can be respectively formed with N and s poles. The poles formed by the first extension portion 313 and the first permanent magnet 211 and the upper end of the second permanent magnet 212 are repelled by the N pole. In addition, the s pole formed by the second extension portion 314 and the first permanent magnet 21丨The N-pole is attracted to the lower end of the second permanent magnet 212, so that the permanent magnets 211, 212 can be pushed downward. On the contrary, as shown in FIG. 7B, when an opposite current is applied, the first extension portion 313 and the second extension portion 314 are respectively formed into s and N poles, so that the permanent magnets 211, 212 are pushed upward. Thus, by controlling the direction of the current to affect the direction of the gravitational force generated by the electromagnetic actuation, the permanent magnets 211, 212 and the linear axial movement of the sleeve 21 can be driven by the above embodiment, for the purpose of illustration only. The implementation of the creation is not an example of implementation. Anybody who is familiar with the skill of the art, M3 03 3 94, after the content, can easily think of a few changes. For example, in the embodiment shown in Figure 6, the carrier 124 is a hollow cube. However, we can easily think about it and replace it with a polygonal cylinder and increase the number of magnets to achieve the same effect. 〃 以上 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的That is to say, the generalization of the creation of the towel will not lose the essence of the creation, nor the spirit and scope of the creation, so it should be regarded as the further implementation of the creation.
