Description

攝像頭裝置及移動終端
本發明涉及一種攝像頭裝置和具有該攝像頭裝置的移動終端。
隨著智能電子設備的不斷發展，對智能設備中的攝像頭裝置的要求越來越高。智能電子設備，比如智能手機正朝向輕薄化發展和設計，相應地，攝像頭裝置也要求向小型化甚至微型化發展。現有的智能手機厚度已經減小到幾個毫米，比如6、7毫米，被安裝的攝像頭裝置的厚度尺寸需要小於手機厚度，如何進一步降低攝像頭裝置的厚度成為急需解決的問題。
鑒於上述狀況，本發明提供一種厚度薄的攝像頭裝置和具有該攝像頭裝置的移動終端。
一種攝像頭裝置，包括：鏡頭組件；驅動器，用於驅動所述鏡頭組件；和感光組件，設置在所述鏡頭組件的底部，所感光組件包括濾波片、感光芯片和第一電路板。所述第一電路板上開設通槽，所述感光芯片收容在所述通槽內，所述濾波片固定在所述第一電路板一側並覆蓋所述通槽，所述感光組件還包括第二電路板，所述第二電路板固定在所述第一電路板背離所述濾波片的一側並與所述第一電路板電連接，所述感光芯片與所述第二電路板電連接。
優選地，所述感光芯片通過導線與所述第二電路板電連接，所述導線收容在所述通槽內。

優選地，所述攝像頭裝置還包括一電連接元件，電連接於所述第一電路板，所述電連接元件用於連接外部電源或電設備。
一種移動終端，所述移動終端包括上述任一項所述的攝像頭裝置。
上述攝像頭裝置和具有該攝像頭裝置的移動終端本通過將感光芯片設置在第一電路板上的通槽內，並利用第二電路板降低所述感光芯片與所述第一電路板的電連接位置，使得所述濾波片可以直接設置於所述第一電路板上，消除所述濾波片與所述第一電路板之間的距離，無需另外設置安裝所述濾波片的支架和預留所述感光芯片的安裝空間，從而達到減少攝像頭裝置的厚度尺寸的目的。
下面將結合本發明實施例中的附圖，對本發明實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅是本發明一部分實施例，而不是全部的實施例。基於本發明中的實施例，本領域普通技術人員在沒有做出創造性勞動前提下所獲得的所有其他實施例，都屬於本發明保護的範圍。
請參閱圖1和圖2，攝像頭裝置100包括鏡頭組件10、驅動器20和感光組件40，所述驅動器20用於驅動所述鏡頭組件10以調整所鏡頭組件10的焦距，所述感光組件40設置在所述鏡頭組件10的底部。所感光組件40包括濾波片41、感光芯片42、第一電路板43和第二電路板44。所述第一電路板43上開設通槽434，所述感光芯片42收容在所述通槽434內。所述濾波片41固定在所述第一電路板43一側並覆蓋所述通槽434。所述第二電路板44固定在所述第一電路板43背離所述濾波片41的一側並與所述第一電路板43電連接，所述感光芯片42與所述第二電路板44電連接。
所述攝像頭裝置100包括一安裝座30，所述安裝座30固定設置在所述第一電路板43上並架設於所述濾波片41上方。所述鏡頭組件10和所述驅動器20設置在所述安裝座30上，所述驅動器20與所述第一電路板43電連接。具體地，所述安裝座30的上端面設置第一固定件31，所述驅動器20通過所述第一固定件31固定安裝在所述安裝座30上。所述安裝座30的下端面通過第二固定件431固定設置所述第一電路板43上。在一實施例中，所述第一固定件31和所述第二固定件431可以是黏合膠、熱熔膠等，使所述第一電路板43、所述驅動器20和所述安裝座30之間通過黏接固定。
所述安裝座30上開設安裝槽33，所述安裝槽33貫穿所述安裝座30，所述濾波片41位於所述安裝槽33下方。所述驅動器20具有與所述安裝槽33連通的內腔21，所述鏡頭組件10與所述驅動器20傳動連接並安裝在所述驅動器20的內腔21中。所述驅動器20可以驅動所述鏡頭組件10在所述內腔21和所述安裝槽33組成的空間內上下移動。所述安裝座30的側邊還開設有凹槽32，部分第一電路板43從所述凹槽32露出。所述驅動器20下端設置有對應所述凹槽32的支腳22，所述驅動器20固定在所述安裝座上時，所述支腳22收容在所述凹槽32內並抵觸所述第一電路板43。所述驅動器20可以通過所述支腳22與所述第一電路板43電連接。
請參閱圖3和圖4，所述第一電路板43上的通槽434的邊緣設置第三固定件432，所述濾波片41通過所述第三固定件432固定設置在所述第一電路板43上並覆蓋所述通槽434。在一實施例中，所述第三固定件432可以是黏合膠、熱熔膠等，使所述第一電路板43和所述濾波片41之間通過黏接固定。所述第二電路板44大致呈方框形，通過一連接件45（見圖6）設置於所述第一電路板43的底部。在一實施例中，所述第二電路板44優選為一柔性電路板，所述連接件45為導電膠，優選為各向異性導電膠膜（Anisotropic conductive film, ACF），所述第二電路板44通過所述連接件45與所述第一電路板電連接。ACF膠只在Z方向上導電，而X，Y方向上不導電，即只在圖6視角的豎直方向上導電，不在水平方向上導電，從而避免第一電路板43與第二電路板44的側邊接觸發生短路。在另一實施例中，所述第一電路板43和所述第二電路板44通過鍍銅等技術進行電連接，所述連接件45為可以進行鍍銅或錫焊的電連接件。
所述感光芯片42邊緣設置第一電連接部422，所述第二電路板44上設置有對應所述第一電連接部422的第二電連接部441。所述感光芯片42通過至少一根導線421與所述第二電路板44電連接。所述第一電連接部422和所述第二電連接部441均包括多個電路介面，所述導線421的兩端分別焊接於所述第一電連接部422和所述第二電連接部441上對應的電路介面處。
請繼續參閱圖5和圖6，所述攝像頭裝置100還包括第一蓋板46，所述第一蓋板46固定設置在所述第二電路板44背離所述第一電路板43的一側，即所述第二電路板44的底面。收容在所述通槽434內的所述感光芯片42固定設置在所述第一蓋板46上對應所述通槽434的區域。在一實施例中，所述第一蓋板46可以是一鋼板或其他金屬板，覆蓋在所述攝像頭裝置100的底部，保護所述攝像頭裝置100的內部結構的同時，還用於散失所述感光芯片42產生的熱量。除金屬材料外，所述第一蓋板46還可以由其他高強度材料製成。所述感光芯片42可以通過熱熔膠或黏合膠等貼附於所述第一蓋板46表面，在其他實施例中，所述感光芯片42還可以通過焊接或表面貼片技術等固定設置在所述第一蓋板46上。
貼附在所述第一蓋板46上所述感光芯片42容置在所述通槽434和所述第二電路板44的中心通孔組成的空間內，所述導線421也收容在所述通槽434內。換句話說，所述感光芯片42上端面低於所述第一電路板43的上端面，所述導線421的最高點低於所述第一電路板43的上端面。在傳統技術方案中，感光芯片42和導線421直接設置在第一電路板43表面，濾波片41不得不與第一電路板43間隔設置。本申請的技術方案通過將感光芯片42和導線421設置在第一電路板43上的通槽內，再利用第二電路板44降低所述感光芯片與所述第一電路板的電連接位置以降低所述導線421的最高點，使得所述濾波片41可以直接設置於所述第一電路板43上，消除所述濾波片41與所述第一電路板43之間的距離，達到減少攝像頭裝置100的厚度尺寸的目的，無需另外設置濾波片41的支架和預留所述感光芯片42及其導線421的安裝空間，將攝像頭裝置100的厚度尺寸至少減少0.36mm。
請再次參閱圖1和圖2，所述攝像頭裝置100還包括一電連接元件50，用於連接外部電源或電設備。所述電連接元件50包括第三電路板51、第二蓋板52和電連接器53。所述第三電路板51通過一連接板433電連接於所述第一電路板43。所述第二蓋板52貼附於所述第三電路板51的一側，用於保護所述第三電路板51。所述電連接器53設置在所述第三電路板51背離所述第二蓋板52的一側，所述電連接元件50通過所述電連接器53與外部電源或電設備連接。
請參閱圖7，本申請還提供一種移動終端200，所述移動終端包括處理器201和上述攝像頭裝置100。所述處理器201電連接所述攝像頭裝置100的電連接元件50，以控制所述攝像頭裝置100。
以上實施方式僅用以說明本發明的技術方案而非限制，儘管參照以上較佳實施方式對本發明進行了詳細說明，本領域的普通技術人員應當理解，可以對本發明的技術方案進行修改或等同替換都不應脫離本發明技術方案的精神和範圍。
