Description of the Invention: [Technical Field of the Invention] The present invention is directed to a voice coil motor, and more particularly to a voice coil horse that can stably move a brain piece. [Prior Art] In order to fine-tune the head arm of a lens group or a hard disk The positioning control usually uses a voice coil motor (voice c〇11 M enemy, VCM) that can move the moving parts to move the lens group or the hard-face arm. The mechanism of the phase motor of the moving parts is mainly placed in a magnetic circuit containing permanent magnets. In the optical system, when the current passes through the coil, the magnetic field formed by the permanent magnet is based on the propulsive force of the left hand of the left hand, so that the socket of the permanent magnet is moved while the belt is fixed on the socket. Mirror joy, and the purpose of optical zoom, focus. ^Please refer to the figure '1A~_ is a schematic diagram of a conventional voice coil motor. As shown in Figures 1A to 1B, the conventional voice coil motor (4) m--------------------------------------------------------------------------------------------------------------------------------------------------------------- At the same time, the plurality of guiding axes 12 fixed on the bottom 10 have 19 M and the corresponding objects are increased (four) 丨, and the object ^ can be moved up and down according to a plurality of _ axes. If the carrier 10 is right and optical focusing is to be performed 1, 201212493 I will take the circuit of the circuit components (unscaled) to obtain power, and then provide the fixed magnetic, s, and magnetic components (not depicted). By interacting with each other, the movable magnetic path member/and the lens is moved up and down by a plurality of guide axes 12 (usually referred to as 2A'' 2A, the figure is a conventional voice coil motor posture. Difficult dry:: During the above movement, based on the magnetic attraction of the magnetic sensing element to the guide that has been worn through the perforation, the guiding shaft 12 will be close to and in contact with the hole of the perforation 101, and the guiding metal 12 respectively, the hole of the perforation 101 is in a single-point contact (when viewed in a plan view), regardless of whether the axis of the guide shaft 12 slides in the perforation 101 or the axis slides on the plane, from the perspective of the three-dimensional space, The shaft is in line contact with the hole wall of the perforation m. However, under the action of gravity, the angle of the steering wheel does not cause a certain contact line between the shaft 12 and the perforation 101. In other words, there is no Something greater than the ground, gravitational traction or restriction, in two guides The metal will respectively have a 360 degree annular contact line between the guide shaft 12 and the hole wall of the perforation 101 under the hole-to-point contact of the perforation 1 () 1 (ie, only 2 line contacts). This causes a large potential difference when the load mounting carriage 10 slides or stops sliding along the guide shaft 12, which causes the image of the image pickup lens on the 1Q of the load to be unclear. There is only 2 lines in contact between the upper two guiding metals and the perforations, which leads to the chance that there will be a circular contact line between 201212493, which will cause the load to mount the sliding seat W, bone movement or stop the sliding scale. Big (four) potential difference, but there is no clear material problem. / Qiao / 1 = The main purpose of the invention is to provide a voice coil that can stabilize the moving parts: 'Dream! The wall of the guide hole has 2 points and single-point respectively Line/person 2 point contact provides the main contact position, and _ another - free large single-line contact to absorb the deflection and skew of the guide steel shaft. Also based on the purpose, the hair is stable and moving. _ reaches the bottom = on the seat - (four) female, fixed circuit material (mainly by the coil:, :: magnetic circuit components (including magnetic components) Jane==where the 'mounting slide has two perforations.

Solid can be stable to move ~ ring motor contains the base that is, fixed electricity == (main 2_4 () 1 and 4 () 2 (based on magnetic metal), Kushiro 50 (mainly by the coil to construct the magnetic element (4) and rigidly connected with the load mounting slide can be:: ^ tail 62). Among them, the load is installed 201212493 months I, there are two different shaped holes perforation (10) and 6〇2 and The perforations 6〇1 and 6〇2/sentence are sufficient to be respectively passed by the set of guiding axes 4〇1 and 4〇2. When the set of guiding axes ', 4〇2 are magnetically conductive metals, the magnetic sensing element 61 & The thin guide shafts 401 and 402 of the leakage magnetic field and the magnetic permeability generate a magnetic attraction force. Fig. 4 is a view showing a second embodiment of the voice coil motor of the present invention. #图斤 shows the voice coil motor of the present invention which can stably move the moving parts, including the base, the mouth, the set of guide shafts, the assembly (non-magnetic material), and the fixed circuit. The device 50 (mainly composed of a coil), the movable magnetic circuit member clearly includes a magnetic sensor 1 and the nm is mounted with a mounting bracket 62), and a magnetic metal housing. The perforated legs of the different shaped holes and the holes of (10) 2 and 601 and 602 are sufficient to be respectively passed by the set of guiding axes. When the lead axes 401 and 402 are non-magnetic materials, the leakage magnetic field of the magnetic sensitive element 61 and the magnetic conductive gold contact body 70 generate magnetic attraction. In a simple manner, as shown in FIG. 5, based on the magnetic attraction of the magnetic sensitive element 61 to the guide shafts 401 and 402 that have been worn through the 6〇i 14 602, the guide shaft 4〇1 ” 4〇2 Contacting the holes of the perforations 6G1 and 6Q2. In order to solve the problem of relatively large posture difference when the load ampoule slide 62 slides or stops sliding, the contact between the guide shaft tree and the U01 Λ 602 is one of them. The group is contacted by a single contact line, and the other is called a contact line C2 in contact with G3. Among them, the contact lines C2 and C3 are the main contact lines, and they are guided by the load-sliding slide. 4G2 scales up and down the tree, and rides with (7) to promote the slipping sin effect. The contact line between the guide shaft side and the perforation is a large left-right offset due to the characteristics of the perforated 201212493 structure. Degree of freedom, so as to absorb the offset and skew when a posture difference as shown in Figs. 2A to 2B occurs. In order to exist between the perforation 602 and the guide shaft 402, there are profiles of the above two contact lines C2 and C3 'perforations 602. a hole that is round and has a gradually narrowed portion while perforating the gradual narrowing of the go Contacting the guide 4〇2 metal, or perforated cross-section of 6〇2

In any case, the aperture of the perforation is smaller than the perforation 601 but slightly larger than the guide shaft 4〇2, so that there is a contact line C2 and C3 between the perforation 6〇2 and the guide shaft 402, and it does not become only one- Contact line. Meanwhile, in order to have the contact line C1 between the dental hole 601 and the guide shaft 401 and the hole diameter of the through hole 6〇1 is larger than the through hole 602, the guide shaft 401 is freely displaced left and right in the through hole 6〇1. When viewed from the surface, the perforation 6 () 1 _ surface is rectangular. In addition, if the position or size of the guide shafts 401 and 402, the perforations 601 and 6〇2 are varied during the manufacturing process, the guide shafts 4〇 and 402 are guided as long as the guide shaft is freely offset in the perforation. It can smoothly pass through the perforations 601 and 6〇2 without interference. It should be specially noted that if the difference between the materials in the voice coil is able to be = 掏, w (4) _2 coffee can be round and π has a gradually narrowing or a section like perforation 602 showing a drop or ah Shape, so that the contact between the thin and moving and perforating 6G1 and the coffee, the two contact lines C2 and C3, C4 and C5 are connected to the boat h," as shown in Figure 5B.
