Description of the Invention: [Technical Leadership of the Invention] The present invention relates to a lens focus drive response time (Response Time) suppression method and structure, and more particularly to a response time that can suppress the focus of a micro lens focus drive, and reduces the lens Focusing produces the jitter generated by the movement, and quickly reaches the steady-state green structure. [Previous Branches] Due to the advancement of technology, the size of digital cameras has been reduced considerably, and most mobile phones have the function of digital cameras, which are attributed to the modularization and miniaturization of camera lenses. There are many kinds of autofocus drive structures in the miniature lens. The most commonly used is the voice coil Mae (VCM), which has the advantages of small size, low power consumption, accurate actuation displacement and low price. Suitable as a short-range drive for micro lens autofocus. As shown in FIG. 1 , it is a stereoscopic decomposition of the conventional lens focus drive structure. The focus drive structure includes an upper cover 10, a lower bottom cover 11 and an outer frame 12, and the outer periphery of the outer frame 12 is embedded in four The magnet 13 is provided with a thread in a lens holder 14 and can be screwed into a lens 15 . The lens holder 14 is embedded with a coil 16 outside the lens holder 14 , and the lens holder 14 can move in the outer frame 12 . The center of the four magnets 13 is energized by the coil 16 to generate a magnetic field. The field iron 13 repels or attracts, and the lens holder is driven to focus: 1'3^the lens holder 14 is supported by the upper and lower sides, and 17 is supported by the four. Center. When the coil 16 is energized, the coil 16 generates a thrust with the magnet 13 due to the action of the current magnetic 1325085 field, the frame! 4 Move the position from bottom to top and use the "shocks 17 to push the lens. However, as long as the lens has the focus of autofocus, then slowly == the time required to move to stop, I call it dynamic ringing. Figure 2 shows the behavior of the focus-control structure of the debt-testing. The waveform should not be intent. It can be seen from Figure 2 that it takes 13 seconds to reach steady state, and the time is quite long.

The longer the dynamic response time, the required focusing time. The longer it is, the shorter the dynamic response time is required to effectively improve the time required for focusing, and there is currently no literature or technique to improve this dynamic response time. At the job, the inventor of this case focused on how to improve the lens dynamic time, and finally developed a lens focus drive response time suppression method and structure 'can reduce the dynamic response time of this segment, or even completely eliminate it, is a reasonable design creation . SUMMARY OF THE INVENTION An object of the present invention is to provide a lens focus drive response time suppression method and a structure of an absorbable lens focus drive structure that is moved to a position and stops moving to suppress jitter to suppress dynamic response time (Response Time). In order to improve quality' and achieve efficiency.

The frame 2 is embedded in the displacement to produce a dynamic response time of the movable mechanism. In order to achieve the above object, the present invention provides a dynamic response time suppression method and structure, wherein a plurality of t-focus drives are provided with a movable portion and an immovable portion, and the movable portion is movable. An elastic structure connecting the non-movable mechanism to the non-movable mechanism, and the movable mechanism of the elastic element and the movable mechanism of the non-movable mechanism are connected to the movable mechanism for focusing displacement to generate r Absorb the dynamic response time of the mechanism to steady state. X inhibits the movement and incorporates at least one shock absorbing element 62 (§110) into the accommodating notch 61. The shock absorbing element 62 is coupled between the movable mechanism 50 and the non-movable mechanism 60 (S120) for absorbing the The movable mechanism 5 is displaced to the jitter generated at the time of positioning (S130) to suppress the dynamic response time. 4A, B and FIG. 6A and B are schematic cross-sectional views showing the actuating state of the lens focusing drive structure of the present invention using the shock absorbing member, and the end of the shock absorbing 7C member 62 is attached to the bottom cover 26, The other end is attached to the lower side of the base 21. The shock absorbing member 62 can be a soft gel, a soft spring or a soft rubber material. In addition, in the present invention, the second shock absorbing element 62 is connected between the front cover 25 and the base wire, or between the frame 24 and the base 21, as long as the opening of the lens 31 is avoided, and the front cover 25 and the bottom are also provided. The shock absorbing member 〇2 is disposed between the cover 26 and the (four) 24 and the base 21. Further, since the movable member 28 is provided with the movable portion connecting base 21 and the movable portion is connected to the front cover 25 or the bottom cover 26, The invention can also connect the shock absorbing 462 between the sling element 28 and the front cover 25 or the wire-shaped immovable mechanism 60. Thus, the shock generated by the shock absorbing element 21 base (21) displacement to the positioning can be suppressed. The dynamic response time. Figure 7 is a schematic diagram of the dynamic response waveform after detecting the use of the shock absorbing element of the present invention. It can be seen from FIG. 7 that after the shock absorbing element 62 of the present invention is added, the susceptor 21 directly reaches the steady state when it is displaced to the position, and has no dynamic response time, so that the dynamic response time can be suppressed quite effectively, and the shock absorbing component of the present invention is added. After 62, the shock and vibration test in the product test also has the effect of shock absorption buffer, which makes the product more reliable. 1325085, the present invention can indeed provide a design that is quite different from the prior art by the above-mentioned disclosed technology, which can improve the overall use value, and is not found in the publication or public use before the application, and has already complied with the invention patent. The essentials are to file an invention patent application in accordance with the law. However, the drawings and descriptions disclosed above are only examples of the present invention, and those skilled in the art can make various other modifications according to the above description, and these changes still belong to the inventive spirit of the present invention.
