Abstract
Description
本發明係與鏡頭有關,特別是指一種相機鏡頭防震平台組。The invention relates to a lens, in particular to a camera lens shockproof platform set.
為了克服拍照或攝影時的手震問題,目前最常見之解決方式係於相機鏡頭內部設置可移動式光學感測器,讓相機即使處在些微震動的環境,感測器仍然維持穩定,不會因搖晃而產生模糊影像。In order to overcome the problem of camera shake during photographing or photography, the most common solution at present is to install a movable optical sensor inside the camera lens, so that the sensor remains stable even in a slightly vibrating environment. A blurred image is produced due to shaking.
相機內的防手震機構,如第七圖所示,通常係於一移動平台80直接設置驅動件82與光學感測器84。當相機內部的感應器偵測到相機震動以後,感應器就能產生訊號讓驅動件82帶動移動平台80,用以調整光學感測器84位置,達到抵銷相機之震動幅度,所擷取影像就能更為清晰的目的。The anti-shake mechanism in the camera, as shown in the seventh figure, is usually provided with a driving member 82 and an optical sensor 84 directly on a moving platform 80. When the sensor inside the camera detects the camera shake, the sensor can generate a signal to enable the driving member 82 to drive the moving platform 80 to adjust the position of the optical sensor 84 to offset the amplitude of the camera and capture the image. It will be more clear.
然而,在上述防手震機構的組成構件,光學感測器84與驅動件82都設置於同一移動平台80,驅動件82係偏離平台80之中心位置地位在平台80側邊。當驅動件82帶動平台80偏移時,將會先使平台80靠近驅動件82之部分區域些微移動以後,再帶動整個移動平台80,造成移動平台80無法順暢偏移,而且容易產生出阻力,使得移動較為遲緩,讓光學感測器84無法穩定地擷取影像,降低防手震效果。However, in the components of the anti-shake mechanism described above, the optical sensor 84 and the driving member 82 are both disposed on the same moving platform 80, and the driving member 82 is located at the side of the platform 80 at a position offset from the center of the platform 80. When the driving member 82 drives the platform 80 to be offset, the platform 80 is slightly moved closer to a portion of the driving member 82, and then the entire moving platform 80 is driven, so that the moving platform 80 cannot be smoothly shifted, and the resistance is easily generated. The movement is slow, and the optical sensor 84 cannot stably capture images, thereby reducing the anti-shake effect.
因此,本發明之主要目的乃在於提供一種相機鏡頭防震平台組,其可較為穩定與精確地調整光學感測器的位置,提升防震效果。Therefore, the main object of the present invention is to provide a camera lens anti-vibration platform group, which can relatively stably and accurately adjust the position of the optical sensor and improve the anti-shock effect.
為達成上述目的,本發明所提供之相機鏡頭防震平台組,包含有一第一平台與一第二平台,該第一平台係具有一驅動件;該第二平台係具有一光學感測器,該第二平台可移動地連結於該第一平台,用以使該第一平台可帶動該第二平台位移;藉由上述組成構件,本發明能夠於較為穩定與精確的狀態下移動第二平台,使影像擷取得更為清晰,達到提高防手震效果的目的。In order to achieve the above objective, the camera lens anti-vibration platform group provided by the present invention comprises a first platform and a second platform, the first platform has a driving component; the second platform has an optical sensor, The second platform is movably coupled to the first platform, so that the first platform can drive the second platform to be displaced; and by using the component member, the invention can move the second platform in a relatively stable and accurate state. Make the image more clear and achieve the purpose of improving the anti-shake effect.
有關本發明之詳細構造及其特徵,以下將列舉實施例並配合圖式,在可使本發明領域中具有通常知識者能夠實施本發明實施例的範圍內進行說明。The detailed construction of the present invention and its features are set forth in the following description of the embodiments of the invention.
茲配合圖式列舉若干較佳實施例對本發明進行詳細說明,其中各圖式的簡要說明如下:第一圖係為本發明第一較佳實施例之立體分解圖;第二圖係為本發明第一較佳實施例之局部正視圖,主要顯示第一平台之狀態;第三圖係為本發明第二較佳實施例之立體分解圖;第四圖係為本發明第二較佳實施例之局部正視圖;第五圖係為本發明第三較佳實施例之立體分解圖;以及第六圖係為本發明第三較佳實施例之後視圖。BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be described in detail with reference to the preferred embodiments of the preferred embodiments in which: FIG. 1 is a schematic view of the first preferred embodiment of the present invention; The partial front view of the first preferred embodiment mainly shows the state of the first platform; the third figure is an exploded perspective view of the second preferred embodiment of the present invention; and the fourth figure is the second preferred embodiment of the present invention. 5 is an exploded perspective view of a third preferred embodiment of the present invention; and a sixth view is a rear view of a third preferred embodiment of the present invention.
請先參閱第一及第二圖所示,係為本發明第一較佳實施例所提供之相機鏡頭防震平台組10,包含有一第一平台20與一第二平台30。該第一平台20具有一框體22,框體22之一側邊設有一延伸臂24。延伸臂24位於框體22之近中央位置,且朝外側延伸。延伸臂24外端具有二夾爪26與一形成於夾爪26間之導槽27,導槽27係沿著垂直方向延伸。各夾爪26相對於導槽27之側壁具有一定位部28,第一平台20之延伸臂24下方另設有一驅動件16。Please refer to the first and second figures, which are the camera lens anti-vibration platform group 10 provided by the first preferred embodiment of the present invention, including a first platform 20 and a second platform 30. The first platform 20 has a frame 22, and one of the sides of the frame 22 is provided with an extension arm 24. The extension arm 24 is located near the center of the frame 22 and extends outward. The outer end of the extension arm 24 has two jaws 26 and a guide groove 27 formed between the jaws 26, and the guide groove 27 extends in the vertical direction. Each of the clamping jaws 26 has a positioning portion 28 opposite to the side wall of the guiding groove 27, and a driving member 16 is further disposed under the extending arm 24 of the first platform 20.
第二平台30中央設有一用以擷取影像之光學感測器18,第二平台30之一側邊設有一沿垂直方向延伸之導桿32,第二平台30於導桿32外側位置另設有一感應器14,於本實施例之感應器14係為霍爾感應器(Hall sensor)。An optical sensor 18 for capturing images is disposed in the center of the second platform 30. One side of the second platform 30 is provided with a guiding rod 32 extending in a vertical direction, and the second platform 30 is disposed outside the guiding rod 32. There is a sensor 14, and the inductor 14 in this embodiment is a Hall sensor.
第一平台20係以延伸臂24之二夾爪26嵌設於第二平台30之導桿32,使導桿32藉由各夾爪26之定位部28固定於延伸臂24。當第二平台30與光學感測器18產生震動現象,感應器14隨即偵測出震動幅度,並且發出用以控制驅動件16之訊號,使驅動件16帶動第一平台20呈上下直線狀位移,第一平台20之延伸臂24即可同步推動第二平台30些微位移,作為調整補償震動位移的作用。The first platform 20 is embedded in the guide bar 32 of the second platform 30 by the two jaws 26 of the extension arm 24, so that the guide bar 32 is fixed to the extension arm 24 by the positioning portion 28 of each jaw 26. When the second platform 30 and the optical sensor 18 generate a vibration phenomenon, the sensor 14 detects the amplitude of the vibration and sends a signal for controlling the driving member 16, so that the driving member 16 drives the first platform 20 to move up and down linearly. The extension arm 24 of the first platform 20 can synchronously push the micro-displacement of the second platform 30 as an effect of adjusting the compensation vibration displacement.
由於第一平台20之延伸臂24定位於第二平台30之導桿32,進而再推動第二平台30,可以讓驅動件16的推力直接且平衡地帶動第二平台30上下位移,第二平台30不會產生相對旋轉或是傾斜現象,光學感測器18能夠於較為穩定與精確的狀態下移動,影像擷取得更為清晰,達到提高防手震效果的目的。Since the extension arm 24 of the first platform 20 is positioned on the guide bar 32 of the second platform 30, and then the second platform 30 is pushed, the thrust of the driving member 16 can directly and vertically move the second platform 30 up and down. The second platform 30 does not cause relative rotation or tilting, and the optical sensor 18 can move in a relatively stable and accurate state, and the image is more clearly obtained, thereby achieving the purpose of improving the anti-shake effect.
如第三與第四圖所示,係為本發明第二較佳實施例之相機鏡頭防震平台組40,其亦包含有第一平台41與第二平台42,特點在於第一平台41之延伸臂43具有一樞軸44,樞軸44距離延伸臂43外端之導槽45預定距離。第二平台42設有一固定部46,固定部46成形在第二平台42之側邊中心線位置。第二平台42之固定部46係位於延伸臂43之導槽45內,第一平台41之樞軸44則樞設於一疊設第一與第二平台42之外平台47的定位孔48。藉由上述組成構件,當第一平台41受驅動件49帶動時,第一平台41以樞軸44為中心原地旋轉,延伸臂43利用導槽45帶動第二平台42上下位移。由於固定部46係位於第二平台42之近質量中心位置,延伸臂43即可以較為平均且穩定分佈之力量推動第二平台42,讓第二平台42與光學感測器50較為順暢地移動。As shown in the third and fourth figures, the camera lens anti-vibration platform group 40 of the second preferred embodiment of the present invention further includes a first platform 41 and a second platform 42 and is characterized by an extension of the first platform 41. The arm 43 has a pivot 44 that is a predetermined distance from the guide groove 45 at the outer end of the extension arm 43. The second platform 42 is provided with a fixing portion 46 formed at a side center line position of the second platform 42. The fixing portion 46 of the second platform 42 is located in the guiding groove 45 of the extending arm 43, and the pivot 44 of the first platform 41 is pivotally disposed on the positioning hole 48 of the platform 47 outside the first and second platforms 42. With the above-mentioned constituent members, when the first stage 41 is driven by the driving member 49, the first stage 41 rotates in the center of the pivot 44, and the extending arm 43 drives the second stage 42 up and down by the guiding groove 45. Since the fixing portion 46 is located at the near-mass center position of the second platform 42, the extension arm 43 can push the second platform 42 with a relatively even and stable distribution force, so that the second platform 42 and the optical sensor 50 move relatively smoothly.
再第五及第六圖所示,本發明第三較佳實施例所提供之相機鏡頭防震平台組60,其組成構件概同於第二較佳實施例,特點則在於第一平台61之延伸臂65外端設置一樞軸62,樞軸62樞設於外平台63之定位孔64。而延伸臂65之導槽66設於相距樞軸62預定距離之位置,第二平台67之固定部68係成形在背面近質量中心位置,且位於延伸臂65之導槽66內。藉此當第一平台61移動時,第一平台61亦利用樞軸62為中心偏轉,再經由延伸臂65帶動固定部68,進而穩定地移動第二平台67,同樣可達成本發明之發明目的。Further, in the fifth and sixth figures, the camera lens anti-vibration platform group 60 provided by the third preferred embodiment of the present invention is substantially the same as the second preferred embodiment, and is characterized by the extension of the first platform 61. A pivot 62 is disposed on the outer end of the arm 65, and the pivot 62 is pivotally disposed on the positioning hole 64 of the outer platform 63. The guiding groove 66 of the extending arm 65 is disposed at a predetermined distance from the pivot 62. The fixing portion 68 of the second platform 67 is formed at a position near the center of the back mass and is located in the guiding groove 66 of the extending arm 65. Therefore, when the first platform 61 moves, the first platform 61 is also deflected by the pivot 62, and then the fixing portion 68 is driven by the extending arm 65, thereby stably moving the second platform 67, which can also achieve the purpose of the invention. .
