Description

無轉軸防抖反射模組及潛望式模組Shaftless anti-shake reflection module and periscope module

本發明涉及攝像領域，尤其涉及一種無轉軸防抖反射模組及潛望式模組。The invention relates to the field of photography, in particular to a non-rotating anti-shake reflection module and a periscope module.

隨著使用者對手機等移動終端的拍攝要求越來越高，潛望式模組的需求也越來越大，與傳統的CCM模組定位於小焦距的廣角拍攝不同，潛望式模組定位於大焦距的遠景拍攝，且其遠景拍攝性能能夠達到專業相機的級別，因此，CCM模組和潛望式模組之間配合使用的話，能夠起到很好的功能互補。As users have higher and higher shooting requirements for mobile terminals such as mobile phones, the demand for periscope modules is also increasing. Unlike traditional CCM modules that are positioned for wide-angle shooting with small focal lengths, periscope modules The long-range shooting is positioned at a large focal length, and its long-range shooting performance can reach the level of a professional camera. Therefore, if the CCM module and the periscope module are used together, they can complement each other.

潛望式模組主要包括反射模組和鏡頭模組兩部分，反射模組將成像光線反射90°後入射至所述鏡頭模組內，由所述鏡頭模組進行對焦和成像，在潛望式模組的防抖方案中，一般由所述反射模組負責一個軸上的防抖，由所述鏡頭模組負責另一個軸上的防抖。其中，在反射模組的防抖結構中，帶動反射鏡/反射稜鏡進行轉動防抖的活動座一般通過其中軸方向兩端上的轉軸連接於固定座的軸孔內，導致所述活動座在轉動時，其轉軸不可避免地會與所述固定座的軸孔之間產生轉動摩擦，轉動摩擦損耗掉了一部分驅動力，降低了防抖驅動的精度，而且轉動摩擦的大小與所述轉軸和軸孔之間的鬆緊度相關，即使是使用同一套模具生產出來的反射模組之間，所述轉軸和軸孔之間的鬆緊度由於公差原因也會存在差異，何況在量產時還會同時使用多套模具進行生產，以至於在使用時，同一套防抖驅動演算法對不同反射模組防抖驅動的精度差異大，因此，必須使用霍爾感測器來感測所述活動座的真實轉動角度，使驅動IC能夠依據所述活動座的真實轉動角度來調節電磁線圈的驅動電流，使所述活動座真正轉動至防抖所需的轉動角上。The periscope module mainly includes a reflection module and a lens module. The reflection module reflects the imaging light by 90° and then enters the lens module. The lens module performs focusing and imaging. In the anti-shake solution of the type module, the reflection module is generally responsible for the anti-shake on one axis, and the lens module is responsible for the anti-shake on the other axis. Among them, in the anti-shake structure of the reflection module, the movable seat that drives the mirror/reflector to rotate and anti-shake is generally connected to the shaft hole of the fixed seat through the rotating shafts on both ends of the middle axis direction, resulting in the movable seat When rotating, the rotating shaft will inevitably generate rotating friction with the shaft hole of the fixed seat. The rotating friction loses a part of the driving force and reduces the accuracy of the anti-shake drive. Moreover, the size of the rotating friction and the rotating shaft It is related to the tightness between the shaft holes. Even between the reflective modules produced by the same set of molds, the tightness between the shaft and the shaft hole will be different due to tolerances, not to mention the difference in mass production. Multiple sets of molds are used for production at the same time, so that when in use, the same set of anti-shake driving algorithm has large differences in the accuracy of anti-shake driving of different reflection modules. Therefore, Hall sensors must be used to sense the activity The true rotation angle of the seat enables the driving IC to adjust the driving current of the electromagnetic coil according to the true rotation angle of the movable seat, so that the movable seat can actually rotate to the rotation angle required for anti-shake.

為了解決上述現有技術的不足，本發明提供一種無轉軸防抖反射模組及潛望模組。該無轉軸防抖反射模組內的活動座和固定座之間在防抖時不會產生摩擦力，使得驅動力損耗差異小，防抖精度差異小，尤其適用於開環防抖方案。In order to solve the above-mentioned shortcomings of the prior art, the present invention provides a shaftless anti-shake reflection module and a periscope module.

下面結合附圖和實施例對本發明進行詳細的說明。The present invention will be described in detail below in conjunction with the drawings and embodiments.

實施例一Example one

如圖1和2所示，一種無轉軸防抖反射模組，包括固定座1、活動座2、反射鏡/反射稜鏡3、電磁驅動機構，所述反射鏡/反射稜鏡3裝配在所述活動座2上；所述活動座2通過彈片組與所述固定座1連接，以懸浮於所述固定座1內；所述電磁驅動機構包括設置在所述固定座1上的電磁線圈5和設置在所述活動座2上的永磁體4，所述電磁線圈5通電後和永磁體4之間形成一磁場合力，以驅動所述活動座2帶動所述反射鏡/反射稜鏡3產生傾斜；所述彈片組形成一回彈合力，與所述磁場合力共同作用，使得所述活動座2帶動所述反射鏡/反射稜鏡3停留在防抖所需的傾斜位置上。As shown in Figures 1 and 2, a non-rotating anti-shake reflection module includes a fixed base 1, a movable base 2, a mirror/reflection frame 3, an electromagnetic drive mechanism, and the mirror/reflection frame 3 is assembled in the The movable seat 2; the movable seat 2 is connected to the fixed seat 1 through a set of shrapnel to be suspended in the fixed seat 1; the electromagnetic drive mechanism includes an electromagnetic coil 5 arranged on the fixed seat 1 And the permanent magnet 4 arranged on the movable seat 2. After the electromagnetic coil 5 is energized, a magnetic field resultant force is formed between the permanent magnet 4 to drive the movable seat 2 to drive the reflector/reflector 3 to produce Tilt; The elastic sheet group forms a resilience force, and the combined force of the magnetic field acts together, so that the movable seat 2 drives the mirror/reflection ridge 3 to stay in the tilt position required for anti-shake.

該無轉軸防抖反射模組中的活動座2通過所述彈片組連接懸浮於所述固定座1內，在所述電磁驅動機構驅動所述活動座2產生傾斜的過程中，所述活動座2不會受到來自於所述固定座1的摩擦力干擾，使得不同無轉軸防抖反射模組之間的驅動力損耗差異小，在同一套防抖驅動演算法下的防抖精度差異小，尤其適用於開環防抖方案。The movable seat 2 in the non-rotating anti-shake reflection module is suspended in the fixed seat 1 through the elastic sheet group connection. When the electromagnetic drive mechanism drives the movable seat 2 to tilt, the movable seat 2 It will not be interfered by the friction force from the fixed seat 1, so that the difference in driving force loss between different shaft-free anti-shake reflection modules is small, and the difference in anti-shake accuracy under the same set of anti-shake driving algorithm is small. Especially suitable for open-loop anti-shake solutions.

本實施例中，所述彈片組由第一彈片8和第二彈片9組成，所述第一彈片8和第二彈片9均在同一側上對所述活動座2和固定座1進行單側連接，使得所述活動座2上與所述固定座1連接的一側具有較低的自由度，而沒有與所述固定座1連接的相對另一側具有較高的自由度；在防抖時，驅動IC向所述電磁線圈5通入驅動電流，使之產生一可變磁場，所述可變磁場和所述永磁體4的恆磁場之間形成的所述磁場合力作用在所述活動座2上時，由於所述活動座2上與所述固定座1連接的一側移動量較小，而沒有與所述固定座1連接的相對另一側移動量較大，所述活動座2會形成以所述第一彈片8和第二彈片9作為擺臂的擺動傾斜。In this embodiment, the shrapnel group is composed of a first shrapnel 8 and a second shrapnel 9. Both the first shrapnel 8 and the second shrapnel 9 are on the same side for unilateralizing the movable seat 2 and the fixed seat 1. Connection, so that the side of the movable seat 2 connected to the fixed seat 1 has a lower degree of freedom, while the opposite side not connected to the fixed seat 1 has a higher degree of freedom; When the magnetic coil 5 is driven by the drive IC to generate a variable magnetic field, the combined force of the magnetic field formed between the variable magnetic field and the constant magnetic field of the permanent magnet 4 acts on the activity When the seat 2 is on, since the movable seat 2 has a smaller movement amount on the side connected to the fixed seat 1, while the opposite side that is not connected to the fixed seat 1 has a larger amount of movement, the movable seat 2 will form a swing tilt with the first elastic piece 8 and the second elastic piece 9 as the swing arm.

在防抖時，所述活動座2的擺動傾斜可以分解為一個繞其中軸方向Y的轉動動作和一個沿入光軸方向X或出光軸方向Z的平移動作，分別對應於一個繞其中軸方向Y的轉動角和一個沿入光軸方向X或出光軸方向Z的平移量，其中，繞其中軸方向Y的轉動角就是手機等終端上的CPU依據陀螺儀在檢測到用戶手部抖動後而計算出的用於糾正在入光軸方向X上的抖動所需所述反射鏡/反射稜鏡3轉動的轉動角；而沿入光軸方向X或出光軸方向Z的平移量沒有改變成像光線的出射方向，因此不會對防抖產生影響。In anti-shake, the swing and tilt of the movable seat 2 can be decomposed into a rotation movement around its middle axis direction Y and a translation movement along the light incident axis direction X or light output axis direction Z, respectively corresponding to a movement around its middle axis direction. The rotation angle of Y and a translation along the direction of the light-in axis X or the direction of the light-out axis Z, where the rotation angle around the middle axis direction Y is determined by the CPU on the mobile phone and other terminals after detecting the user's hand shake according to the gyroscope. The calculated rotation angle of the mirror/reflector 3 to correct the jitter in the direction of the incident axis X; the amount of translation along the direction of the incident axis X or the direction of the output axis Z does not change the imaging light The direction of exit, so it will not affect the anti-shake.

Similarly, the rebound resultant force does not have a component force in the central axis direction Y of the movable seat 2; the magnetic field The direction of the resultant force and the direction of the resultant rebound force are not on the same straight line, that is, there is a non-90° included angle between the resultant magnetic field and the resultant rebound force, or between the resultant magnetic field and the resultant rebound force The directions are parallel but the action points on the movable seat 2 are different.

本實施例中，所述電磁線圈5通電產生的可變磁場的磁場方向垂直於所述活動座2的中軸方向Y，同樣的，所述永磁體4產生的恆磁場的磁場方向也垂直於所述活動座2的中軸方向Y；所述第一彈片8對所述活動座2的第一回彈力垂直於所述活動座2的中軸方向Y，同樣的，所述第二彈片9對所述活動座2的第二回彈力也垂直於所述活動座2的中軸方向Y。In this embodiment, the magnetic field direction of the variable magnetic field generated by the electromagnetic coil 5 is perpendicular to the central axis direction Y of the movable seat 2. Similarly, the magnetic field direction of the constant magnetic field generated by the permanent magnet 4 is also perpendicular to all The central axis direction Y of the movable seat 2; the first resilient force of the first elastic piece 8 to the movable seat 2 is perpendicular to the central axis direction Y of the movable seat 2. Similarly, the second elastic piece 9 opposes the The second resilience force of the movable seat 2 is also perpendicular to the central axis direction Y of the movable seat 2.

所述磁場合力的方向與入光軸方向X和出光軸方向Z之間均呈一定夾角。具體的，若所述電磁線圈5和永磁體4之間沿入光軸方向X進行設置，則所述電磁線圈5和永磁體4之間需沿出光軸方向Z稍微相對錯開；若所述電磁線圈5和永磁體4之間沿出光軸方向Z進行設置，則所述電磁線圈5和永磁體4之間需沿入光軸方向X稍微相對錯開。The direction of the resultant force of the magnetic field forms a certain angle with the direction X of the optical axis and the direction Z of the optical axis. Specifically, if the electromagnetic coil 5 and the permanent magnet 4 are arranged along the optical axis direction X, the electromagnetic coil 5 and the permanent magnet 4 need to be slightly offset along the optical axis direction Z; if the electromagnetic coil The coil 5 and the permanent magnet 4 are arranged along the optical axis direction Z, and the electromagnetic coil 5 and the permanent magnet 4 need to be slightly staggered along the optical axis direction X.

其中，若所述電磁線圈5和永磁體4之間沿入光軸方向X進行設置，則所述第一彈片8和第二彈片9之間也沿入光軸方向X進行設置，且所述第一彈片8和第二彈片9所在的平面均與入光軸方向X相垂直；若所述電磁線圈5和永磁體4之間沿出光軸方向Z進行設置，則所述第一彈片8和第二彈片9之間也沿出光軸方向Z進行設置，且所述第一彈片8和第二彈片9所在的平面均與出光軸方向Z相垂直。Wherein, if the electromagnetic coil 5 and the permanent magnet 4 are arranged along the optical incident axis direction X, the first elastic piece 8 and the second elastic piece 9 are also arranged along the optical incident axis direction X, and the The planes on which the first elastic piece 8 and the second elastic piece 9 are located are perpendicular to the light-incident axis direction X; if the electromagnetic coil 5 and the permanent magnet 4 are arranged along the light-emitting axis direction Z, the first elastic piece 8 and The second elastic pieces 9 are also arranged along the light output axis direction Z, and the planes on which the first elastic pieces 8 and the second elastic pieces 9 are located are perpendicular to the light output axis direction Z.
