Description
Technical field
The utility model relates to a kind of focusing mechanism, particularly relates to a kind of focusing mechanism with segmentation focus function.
Background technology
The conformability electronic product that digital camera is arranged in the portable electronic devices (as mobile phone, PDA(Personal Digital Assistant), notebook computer etc.) has become the common commodity of daily life, and because portable electronic devices payes attention to quite that it is compact, it is the mechanism design problem of making great efforts now that the camera that therefore will have a certain volume is mounted to portable electronic devices inside.
With regard to digital camera, because it need be adjusted lens location and take to obtain suitable focal length, therefore it all has the mechanism that adjusts lens focus mostly, in the prior art, usually all be to utilize direct current or step motor to cooperate gear train to reach the purpose of focusing with the relative position of adjusting eyeglass and photo-sensitive cell, yet complicated gear train is except the problem that meeting appearance and portable electronic devices assembling are difficult for, and the while also can produce irritating mechanicalness noise.
In order to overcome the problems referred to above, here two-part camera lens Focusing mechanism produces in, this mechanism is the magnetic field that utilizes inner coil groups energising back to be produced, the reciprocation of set magnet and magnetic conductive component (as yoke) drives camera lens module and moves forward and backward on the camera lens module, for instance, when the user need carry out shooting at close range, on the magnetic field that coil groups generated that this mechanism utilizes energising and the camera lens module set magnet produce an interactive magnetic force and with camera lens module toward direction promotion away from photo-sensitive cell, held by the suction between magnet and the magnetic conductive component and till making that camera lens module is positioned on the position of close-perspective recording focal length up to camera lens module.Otherwise, when the user will carry out wide-long shot, this mechanism changes the electrical current direction in order to change the magnetic direction that coil groups generated of energising, and with camera lens module on set magnet produce an interactive magnetic force so that camera lens module moves toward the direction near photo-sensitive cell, held by the suction between magnet and another magnetic conductive component up to camera lens module, and till making that camera lens module is positioned on the position of bat focal length far away.Hence one can see that, no matter be closely or wide-long shot, camera lens module all is to be positioned at the close-perspective recording focal length or the position of far clapping focal length by the suction between magnet and the magnetic conductive component, when being rocked yet if this mechanism is in driving condition not (this moment camera lens module held by the suction between magnet and the magnetic conductive component and the position and the coil groups that are positioned at bat focal length far away is in not "on" position), often will be because of magnet set on the camera lens module and the not enough camera lens module disengaging magnetic conductive component that causes of the suction between the magnetic conductive component, so that produce the camera lens module phenomenon of knocking gear inside back and forth, so not only can increase the in-house probability that particulate occurs, the while camera lens module clashes into the sound that is sent back and forth more can allow the user produce the negative impression that mechanism damages.
The utility model content
The purpose of this utility model is to provide a kind of focusing mechanism with segmentation focus function, to solve the above problems.
The purpose of this utility model is achieved in that promptly provides a kind of focusing mechanism, and it includes a support; One load bearing seat, it is socketed in this support in a movable manner, and this load bearing seat is used for carrying a camera lens; One magnetic element is arranged on this load bearing seat; One magnetic conductive part is arranged at a side of this load bearing seat, is used for attracting this magnetic element; One flexible member is arranged at a side of this support and is connected in this load bearing seat, is used for this load bearing seat is positioned a primary importance; And a magnetic field generation device, around being arranged on this support, being used for producing a magnetic field and being positioned a second place because of the suction between this magnetic element and this magnetic conductive part to drive this load bearing seat.
The utility model discloses a kind of focusing mechanism in addition, and it includes a support; One load bearing seat, it is socketed in this support in a movable manner, and this load bearing seat is used for carrying a camera lens; One magnetic conductive part is around being arranged on this load bearing seat; One magnetic element is arranged at a side of this load bearing seat, is used for attracting this magnetic conductive part; One flexible member is arranged at a side of this support and is connected in this load bearing seat, is used for this load bearing seat is positioned a primary importance; And a magnetic field generation device, around being arranged on this load bearing seat, being used for producing a magnetic field and being positioned a second place because of the suction between this magnetic element and this magnetic conductive part to drive this load bearing seat.
Advantage of the present utility model is that it utilizes the setting of flexible member to fix the position of the inner load bearing seat of focusing mechanism.When focusing mechanism is in not driving condition, this moment, flexible member provided a strength to make load bearing seat can be fixed in a position, if therefore focusing mechanism is in vibrating state, load bearing seat still can remain on this position, make load bearing seat break away from this position even rock too fierce, flexible member still can be fixed in load bearing seat once more this position and the load bearing seat phenomenon of percussion device inside back and forth can not take place this moment, thus, can reduce device inside greatly particulate occurs and installs the probability that inner member damages.
