SUMMARY OF THE INVENTION The purpose of the invention is to provide an automatic focusing module seat and structure, which can increase the magnetic field efficiency of the magnetic field at the corner of the coil and achieve the purpose of power saving.冋,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Externally, to drive the bearing, the coil can be assembled, and the four corner positions of the outer frame are respectively set to focus in one direction, and the board 'extends to the line_bearing seat U======================= Your review board can further understand the techniques, means and effects of the invention for achieving the purpose. Please refer to the detailed description and drawings of the invention. I believe that the stomach of this invention can be obtained. And the specific solution, two:, characteristics and special reference and use, and (4) the hair (four) to _. Only k, as shown in FIG. 3, is the first embodiment of the present invention. Figure 4 is a partial part of the combination of the components of Figure 3 of the present invention. Figure 4 The autofocus module of the present invention includes at least a magnet I-bearing seat 34, at least - elastic member %, - 30, four coils. 38' wherein the outer frame 3G is square, the magnets 32 can be assembled at the edge of the metal material, and the carrier is % hollowed out: the group can be inside. The lens 5G is assembled, and the elastic member 36 is used to include the outer edge fixing portion and the inner edge movable portion, and the bearing seat 34 is coupled to the inner edge movable portion of the elastic member 36, and the sexual member 36 The outer edge fixing portion is connected to the outer frame Deng Er by the bolster 37: a space for up and down movement is formed between the truss 37 and the outer frame 30, so that the accommodating seat 34 can be suspended and moved inside the outer frame 3〇. The coil 38 has a square hollow ring shape and can be assembled on the outside of the bearing seat 4. After the power is applied, an electromagnetic field can be generated, and the magnets can be replied to or replied to drive the carrier 34 up and down automatically. The action of focusing. A receiving space 41 is formed in the four corners of the outer side of the bearing block 34 and the coils. The receiving space 34 is preferably located at four corners to form an inwardly retracting channel to form the receiving space 41. . Wherein the four corner positions of the outer frame 30 are respectively provided with an L-shaped plate 40 bent inwardly from the top edge, and extending into the accommodating space 41 formed between the bearing seat 34 and the coil 38, and the L The stencil 40 just corresponds to the space formed between the two magnets 32 via the coil 38. Preferably, the l-type plate 40 is integrally formed with the outer frame 30, and the electromagnetic field of the coil at the corner edge can be strengthened. The magnetic efficiency of the drive. According to the actual experimental results, the present invention can effectively enhance the magnetic field efficiency of the coil at the corner by up to 195 times by the L-shaped plate at the corner of the outer frame disclosed above, thereby increasing the driving force of the electromagnetic field of the coil to achieve power saving. The effect "can provide a design that is different from the well-known person, can improve the overall use value" and has not been seen in the publication or public use before the application, Cheng has already met the requirements of the invention patent, and filed an invention patent application according to law. However, the drawings and descriptions disclosed above are merely exemplary embodiments of the present invention, and those skilled in the art can make various other modifications based on the above descriptions.
