Description
本發明涉及光學系統領域,尤其涉及一種對焦鏡頭模組。 The present invention relates to the field of optical systems, and in particular, to a focus lens module.
隨著多媒體技術之飛速發展,數位相機、攝像機及帶有攝像頭之手機愈來愈受廣大消費者青睞,在人們對數位相機、攝像機及手機攝像頭拍攝物體之影像品質提出更高要求之同時,對數位相機、攝像機及帶有攝像頭之手機等產品需求量亦日益增加。數位相機、攝像機及手機攝像頭等攝影裝置中,鏡頭模組為不可缺少之部件。 With the rapid development of multimedia technology, digital cameras, camcorders and mobile phones with cameras are increasingly favored by consumers. While people are demanding higher image quality for digital cameras, camcorders and mobile phone cameras, Demand for products such as digital cameras, camcorders and mobile phones with cameras is also increasing. In a camera such as a digital camera, a video camera, and a mobile phone camera, the lens module is an indispensable component.
相機模組通常包括鏡筒、鏡座、光學成像元件與影像感測器。所述光學成像元件收容於鏡筒,所述影像感測器設置於鏡座,所述光學成像元件與影像感測器藉由鏡筒與鏡座之間之配合光學耦合。隨著人們對於相機模組成像品質要求之提高,對焦功能成為相機模組普遍具備之功能之一。現有之對焦之相機模組係利用驅動馬達或音圈馬達帶動鏡筒或鏡座發生位移從而改變相機模組之鏡筒與鏡座之間距實現對焦,然而,該相機模組不僅成本高,而且,由於驅動馬達或音圈馬達之存在,使得整個鏡頭模組體積較大且結構複雜,無法滿足人們對於相機模組之輕薄短小之需求。 The camera module usually includes a lens barrel, a lens holder, an optical imaging element, and an image sensor. The optical imaging component is received in the lens barrel, the image sensor is disposed on the lens holder, and the optical imaging component and the image sensor are optically coupled by a cooperation between the lens barrel and the lens holder. As people's imaging quality requirements for camera modules have increased, the focus function has become one of the functions commonly found in camera modules. The existing focusing camera module uses a driving motor or a voice coil motor to drive the lens barrel or the lens holder to shift, thereby changing the distance between the lens barrel of the camera module and the lens holder to achieve focusing, however, the camera module is not only costly, but also Due to the existence of the drive motor or the voice coil motor, the entire lens module is large in size and complicated in structure, which cannot meet the demand for the lightness and thinness of the camera module.
有鑑於此,提供一種成本低、結構簡單且佔用空間小之對焦鏡頭 模組實屬必要。 In view of this, a focusing lens with low cost, simple structure and small space is provided. Modules are necessary.
一種對焦鏡頭模組包括鏡座、鏡筒與彈性元件。所述鏡座收容有影像感測器且開設有複數沿鏡座軸向延伸之滑槽。所述鏡筒收容於所述鏡座並收容有光學成像元件。所述鏡筒具有與鏡座之複數滑槽相對應之複數滑塊,所述複數滑塊穿過所述複數滑槽,用於沿所述複數滑槽滑動。所述彈性元件設置於所述鏡座與所述鏡筒之間,用於提供沿鏡座軸向之彈性變形,以使複數滑塊沿所述複數滑槽滑動時使鏡筒相對於鏡座發生沿鏡座軸向之位移,從而改變影像感測器與光學成像元件之間距。 A focusing lens module includes a lens holder, a lens barrel and an elastic component. The lens holder houses an image sensor and is provided with a plurality of sliding grooves extending axially along the lens holder. The lens barrel is received in the lens holder and houses an optical imaging element. The lens barrel has a plurality of sliders corresponding to the plurality of chutes of the lens holder, and the plurality of sliders pass through the plurality of chutes for sliding along the plurality of chutes. The elastic element is disposed between the lens holder and the lens barrel for providing elastic deformation along the axial direction of the lens holder, so that the plurality of sliders slide along the plurality of sliding slots to make the lens barrel opposite to the lens holder A displacement along the axial direction of the mirror mount occurs, thereby changing the distance between the image sensor and the optical imaging element.
本技術方案之對焦鏡頭模組之滑槽沿鏡座之軸向延伸,鏡筒之滑塊沿滑槽移動即可實現鏡筒與鏡座之間相對位置之改變。彈性元件可防止鏡筒與鏡座於不對焦時發生相對位移。本技術方案提供之對焦鏡頭模組之鏡筒於對焦過程中可相對於鏡座平穩地滑動。不僅結構簡單,佔用空間小,適於目前鏡頭模組微型化之趨勢,而且成本低廉,特別適合應用於手機等電子產品。 The sliding groove of the focusing lens module of the technical solution extends along the axial direction of the lens holder, and the slider of the lens barrel moves along the sliding slot to change the relative position between the lens barrel and the lens holder. The elastic element prevents relative displacement of the lens barrel and the lens holder when it is out of focus. The lens barrel of the focus lens module provided by the technical solution can smoothly slide relative to the lens holder during the focusing process. The utility model has the advantages of simple structure, small occupied space, suitable for miniaturization of the current lens module, and low cost, and is particularly suitable for use in electronic products such as mobile phones.

組裝所述對焦鏡頭模組10時,可採用以下步驟:首先,將所述內筒體120與外筒體121藉由外螺紋1201與內螺紋1212之間之作用螺合與一起,從而形成鏡筒12。 When the focus lens module 10 is assembled, the following steps may be taken: first, the inner cylinder 120 and the outer cylinder 121 are screwed together by the action between the external thread 1201 and the internal thread 1212, thereby forming a mirror. Cartridge 12.
其次,使複數滑塊1214一一穿過複數滑槽1127之第二端部1129,將鏡筒12從第二座體112靠近第一端面1122處置入收容座1120之第二收容腔1126,從而將所述鏡筒12結合於第二座體112。 Then, the plurality of sliders 1214 are passed through the second end 1129 of the plurality of chutes 1127, and the lens barrel 12 is disposed from the second body 112 adjacent to the first end surface 1122 into the second receiving cavity 1126 of the receiving seat 1120. The barrel 12 is coupled to the second base 112.
再次,將彈性元件13之下端130設置於所述第一座體110之底面1105。 Again, the lower end 130 of the elastic member 13 is disposed on the bottom surface 1105 of the first seat body 110.
最後,將第二座體112固定於第一座體110。具體地,使鏡筒12與彈性元件13之上端131接觸,使第二座體112之滑槽1127之第一端部1128與第一座體110之突起1107相配合,同時將延伸座1121之固定柱1131***第一座體110之固定孔1108從而得到對焦鏡頭模組10。 Finally, the second seat body 112 is fixed to the first seat body 110. Specifically, the lens barrel 12 is brought into contact with the upper end 131 of the elastic member 13, so that the first end portion 1128 of the sliding groove 1127 of the second base body 112 cooperates with the protrusion 1107 of the first base body 110, and the extension seat 1121 is The fixing post 1131 is inserted into the fixing hole 1108 of the first seat body 110 to obtain the focus lens module 10.
請一併參閱圖1、圖3至圖6,當對焦鏡頭模組10之彈簧13處於自然狀態時,每一滑塊1214均位於與之對應之滑槽1127之第二端部1129。進行對焦時,可使操作桿1215沿滑槽1127移動至第一端部1128,鏡筒12於操作桿1215之帶動下下降並壓縮彈性元件13使彈性元件13發生形變,直至滑塊1214全部承載於所述第一座體110之突起1107,此時彈性元件13之下端130與上端131之間距亦減小 ,鏡筒12與鏡座11之間沿鏡座11軸向之相對距離減小,分別收容於鏡座11與鏡筒12之影像感測器15與光學成像元件14之間距亦減小從而實現對焦。 Referring to FIG. 1 , FIG. 3 to FIG. 6 , when the spring 13 of the focus lens module 10 is in a natural state, each of the sliders 1214 is located at the second end 1129 of the corresponding chute 1127 . When focusing, the operating lever 1215 can be moved along the sliding slot 1127 to the first end portion 1128. The lens barrel 12 is lowered by the operating rod 1215 and compresses the elastic member 13 to deform the elastic member 13 until the slider 1214 is fully loaded. In the protrusion 1107 of the first seat body 110, the distance between the lower end 130 and the upper end 131 of the elastic member 13 is also reduced. The relative distance between the lens barrel 12 and the lens holder 11 along the axial direction of the lens holder 11 is reduced, and the distance between the image sensor 15 and the optical imaging element 14 respectively received in the lens holder 11 and the lens barrel 12 is also reduced. Focus.
可理解,若將滑槽1127設置為階梯形結構,還可實現對焦鏡頭模組10之多段式對焦。 It can be understood that if the chute 1127 is configured as a stepped structure, the multi-stage focusing of the focus lens module 10 can also be achieved.
本技術方案之對焦鏡頭模組10之滑槽1127沿鏡座11之軸向延伸,鏡筒12之滑塊1214沿滑槽1127移動即可實現鏡筒12與鏡座11之間相對位置之改變。彈性元件13可防止鏡筒12與鏡座11於不對焦時發生相對位移。本技術方案提供之對焦鏡頭模組10之鏡筒12於對焦過程中可相對於鏡座11平穩地滑動。不僅結構簡單,佔用空間小,適於目前鏡頭模組微型化之趨勢,而且成本低廉,特別適合應用於手機等電子產品。 The sliding slot 1127 of the focusing lens module 10 of the present technical solution extends along the axial direction of the lens holder 11, and the slider 1214 of the lens barrel 12 moves along the sliding slot 1127 to realize the change of the relative position between the lens barrel 12 and the lens holder 11. . The elastic member 13 prevents relative displacement of the lens barrel 12 and the lens holder 11 when it is out of focus. The lens barrel 12 of the focus lens module 10 provided by the technical solution can smoothly slide relative to the lens holder 11 during focusing. The utility model has the advantages of simple structure, small occupied space, suitable for miniaturization of the current lens module, and low cost, and is particularly suitable for use in electronic products such as mobile phones.
