Description of the Invention: [Technical Field] The present invention relates to an optical lens module, and more particularly to an autofocus optical lens module. [Prior Art] The new patent No. M294046 of the Chinese Patent Publication No. M294046 discloses an autofocus lens module comprising a bottom cover, two guide tips, two conductive sheets, a lower frame two lens sleeves, two springs, a lens, a coil, and an upper The frame, the two magnets, and the upper cover are composed. The bottom cover is a rectangular frame body, and four brackets for fastening are integrated at the four corners to be integrated with the upper cover buckle, and a through hole is formed in the center for forming a mirror optical path, and the inner surface of the inner surface is provided with two fixings. The holes are respectively inserted into a guide tip; the two conductive sheets are respectively attached to the bottom cover to connect with the same electrode and a central hole is formed between the two conductive sheets for forming the light of the lens, and each of the conductive sheets is provided with a perforation The guiding tip corresponds to the passing; and the lower frame light; the conductive sheet is provided at the center thereof - the central hole is provided for forming the lens, and the lens sleeve is included - the annular frame and the outer ring of the frame ring a perforation is provided for the two guiding ends corresponding to the guiding ends and the holes for assembling the lens; the two springs are respectively sleeved at the bottom ends of the lugs i springs respectively downward (four) on the two pairs of lugs of the lens sleeve, The lens securing ring is sleeved in the lens (4)... in the center hole; the wire is connected to the conductive sheet. (4) Above the frame, the head and tail end wires are divided into the upper frame and the ring frame and the frame ring peripheral two button body, and by the 19563 5 200811502 - the button body and the lens sleeve are fastened to make the upper frame, the coil and the lens cover The tube is disposed on the periphery of the lens to form a barrel group, and the coil is clamped between the frame of the upper frame and the corresponding annular frame of the lens sleeve; and the two magnets are mutually opposite, and the two arcs are The magnets are respectively disposed on the left and right outer edges of the coil; the upper jaw and the bottom cover are integrated to form a lens module, so that the two magnets are clamped between the upper cover and the lower frame, and the two springs are respectively pressed upward. A spring clip is placed on the upper surface of the upper cover between the inner surface of the upper cover and the lug of the lens sleeve. The hunting is performed by the interaction between the coil and the magnet to generate an electromagnetic force to drive the lens barrel 2 to move axially. The two springs are respectively sleeved on the guide tip and elastically supported between the inner surfaces of the upper surface of the lens barrel assembly, so that the lens barrel group can be stabilized. The wire moves. Although the foregoing patent case has disclosed a lens module capable of autofocusing by electromagnetic force, the structure is extremely complicated and limited by the volume limitation of the coil and the iron, so that the overall volume is large, so only the conventional camera f is used. A large-sized digital camera is difficult to use in a thin digital camera or a handheld electronic device with a camera function. • Yang Guo 1Ltd. proposes a spiral wound voltage using a bimorph type piezoelectric ceramic sheet. The electric actuator has been used in a telescopic zooming function for driving light to the lens in the camera, and the piezoelectric actuator is combined with the optical mirror t and the bracket to be placed in the camera and the digital amplifier. Image autofocusing. The spiral-wound piezoelectric actuator has the advantages of small size, large displacement, low power consumption, quietness, and high compatibility. The ceramic tile is wound into a spiral-wound piezoelectric actuator and a large amount of labor must be used when connecting the circuit, even if it is made by using automated tools. The difficulty is high, resulting in low yield and unstable quality of the product 19563 6 200811502. Therefore, the spiral wound piezoelectric actuator is used in a camera, a digital camera or a camera phone, because of the high manufacturing cost and good quality. The rate is low, so there is not much industrial use value. In 1999, Takeshi Morita, Minoru Kuribayashi Kurosawa and Toshiro Higuchi proposed a small piezoelectric motor made of tubular piezoelectric ceramics {Cylindrical Micro Ultrasonic Motor Utilizing Bulk Lead Zirconate Titanate (PZT) 9 Jpn. J. Appl· Phys., Vol· 38, pp· 3347-3350 (1999)}; GD 2003, Shuxiang Dong, Siak Ρ· Lim, Kwork Η· Lee, Jingdong Zhang, Leong C. Lim and Kenjin Uchino et al. propose a small piezoelectric motor made of electrode coated tubular piezoelectric ceramics {Piezoelectric Ultrasonic Micromotor with 1.5 mm Diameter, IEEE Transaction on Ultransonics, Ferroelectircs and Frequency Control, VoL 50, No 4, pp. 361-367 (2003)}; and in 2005, Oleksiy Vyshnevskyy, 10sergej Kovalev and Jan Mehner et al. Also proposed is a small piezoelectric motor made of electrode-coated tubular piezoelectric ceramics {Coupled Tangential-Axial Resonant Modes of Piezoelectric Hollow Cylinders and Their Application in Ultrasonic Motors, IEEE Transaction on Ultransonics, Ferroelectircs and Frequency Control, Vol· 52, No. 1, pp. 31-36 (2005)}. The small piezoelectric motor made of the tubular piezoelectric ceramic or the small piezoelectric motor made of the tubular piezoelectric ceramic coated with the electrode is driven by the wall of the tube, and the shaft of the motor is idling to lose power, and the driving efficiency thereof is driven. With the loss of 7 19563 200811502, the system cannot drive the entire application, so the current research is only in the assembly of small piezoelectric motors and small optical electromechanical systems or consumer electronics. .,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Step by step • Piezoelectric ceramics
