请参阅图1-图4、图8及图9，本发明实施方式的一种摄像头组件10，用于无人机100，摄像头组件10包括支架12和相机模组14，相机模组14安装在支架12，支架12包括用于与无人机100的机身20连接的安装平面121，相机模组14的光轴L相对于安装平面121斜向下倾斜。
本发明实施方式的摄像头组件10，应用于无人机100时，安装平面121可水平地安装在无人机100的机身20上，这样相机模组14可以拍摄到无人机100前方及斜向下方向的场景，拍摄方便，扩大了摄像头组件10的拍摄视角，从而扩大了无人机100航拍的应用场景。
在某些实施方式中，相机模组14的光轴L与水平方向的夹角α为锐角α。如此，相机模组14的拍摄视角较好，可拍摄到无人机100斜向下方向的场景。
具体地，无人机100还设有下视摄像头，相机模组14的光轴L水平斜向下倾斜的角度α为锐角可避免相机模组14的拍摄视角与下视摄像头的拍摄视角重合。
较佳地，锐角α为10-14度。这样，相机模组14的拍摄视角更好。较佳地，本发明实施方式中锐角为12度。当然，在其它实施方式中，锐角α不限于12度。例如，锐角α可以为10度、14度或10-14度之间的其他任意角度。
在某些实施方式中，支架12包括可拆卸地连接的第一支架122和第二支架123，第一支架122和第二支架123连接形成容置空间124，相机模组14包括图像传感器142，图像传感器142收容在容置空间124内。
如此，相机模组14可从支架12拆卸下来，便于维修和更换相机模组14，延长摄像头组件10的使用寿命，提升用户体验。图像传感器142收容在容置空间124内也可以较好地保护图像传感器142。
具体地，容置空间124的尺寸及形状与图像传感器142的尺寸及大小对应。这样使得图像传感器142可以稳定地安装在容置空间124内，从而使得摄像头组件10的结构稳定。当摄像头组件10应用于无人机100进行航拍时，也有助于提升航拍效果。
本发明实施方式中，第一支架122开设有容置槽，容置槽内形成容置空间124。装配时，可先将相机模组14放入容置空间124内，再将第二支架123连接第一支架122，使相机模组14固定在容置空间124内。这样使得摄像头组件10的装配过程更简单快捷。当然，在其他实施方式中，也可分别在第一支架122和第二支架123开设相对设置的容置槽以形成容置空间124。
在某些实施方式中，第一支架122和第二支架123通过卡合的方式连接。如此，第一支架122和第二支架123装配方便快捷，有助于提高摄像头组件10的装配速度，从而提高生产效率。
具体地，第一支架122的外表面设置有凸块1222，第二支架123设置有与凸块1222对应的卡孔1232，通过将凸块1222卡设在卡孔1232内实现将第一支架122和第二支架123通过卡合的方式连接。本发明实施方式中，第一支架122的上表面和两侧表面各设置有一个凸块1222，第二支架123顶部和两侧各设置有一个与凸块1222对应的卡孔1232，其中两侧的卡孔1232的底部形成有缺口1234，凸块1222从缺口1234卡入卡孔1232。这样装配第一支架122和第二支架123时，可将第二支架123从上往下向第一支架122方向移动使顶部的凸块1222和两侧表面的凸块1222卡入对应的卡孔1232实现第一支架122和第二支架123卡合连接，装配方便快捷。
当然，在其他实施方式中，第一支架122和第二支架123的连接方式不限于卡合连接，也可以为其他连接方式，例如螺栓连接，铆接等。
在某些实施方式中，第一支架122包括柱状部1224，柱状部1224开设有通孔1225，相机模组14包括镜筒144，镜筒144容置在通孔1225中，通孔1225的轴向X与相机模组14的光轴L重合。如此，可通过通孔1225的朝向来定位镜筒144的朝向，进而确定相机模组14的朝向，保证相机模组14的斜向下角度准确。
具体地，镜筒144内设有透镜组，图像传感器142位于透镜组的像侧。通孔1225连通容置空间124。装配时，可先将镜筒144插入容置通孔1225并使图像传感器142位于容置空间124内，再将第二支架123安装在第一支架122。如此，可通过通孔1225固定相机模组14的角度，无需调节相机模组14的角度，装配方便快捷。
在其它实施方式中，通孔1225的轴向X可平行于相机模组14的光轴L。
在某些实施方式中，第一支架122与第二支架123的连接处形成有缝隙125，相机模组14包括电路板146，图像传感器142设置在电路板146，电路板146部分地穿过缝隙125并伸出支架12。如此，使电路板146从缝隙125伸出支架12与外部电路连接，将图 像传感器142获取到的图像信息传输至外部电路。
具体地，缝隙125与容置空间124连通，位于容置空间124底部。如此，电路板146在重力的作用下下垂从缝隙125伸出，便于装配。
进一步地，电路板146可为柔性电路板(FPC)。柔性电路板具有配线密度高、重量轻、厚度薄、弯折性好的特点。这样使得电路板146可弯折，摄像头组件10装配更方便。
在某些实施方式中，位于支架12外的电路板146的部位设置有连接器148。如此，便于电路板146与外部电路连接，以实现将图像传感器142获取到的图像信息传输至外部电路。
请参阅图5，在某些实施方式中，摄像头组件10包括导光柱16，导光柱16安装在支架12。如此，导光柱16可为相机模组14补光或者发出提示信号。
具体地，摄像头组件10包括光源(图未示)，导光柱16可利用全反射的方式将光源发出的光导出至相机模组14的前下方。如此，导光效果好。当光线较暗时，可通过导光柱16补光，使相机模组14拍摄到的图像画质更好。当无人机100需要发出提示信号时，光源发光并通过导光柱16导出，作为提示信号。可以理解，光源发出的光可包括多种颜色，每个颜色或颜色的组合可对应于不同的提示信号。
在某些实施方式中，支架12开设有卡槽126，导光柱16卡设在卡槽126，卡槽126包括倾斜的第一抵持面127，导光柱16的侧面为倾斜的第二抵持面162，第一抵持面127与第二抵持面162抵靠。如此，便于将导光柱16安装在支架12。
具体地，在图示的实施方式中，卡槽126开设在第一支架122且靠近柱状部1224设置。如此，导光柱16为相机模组14补光的效果更好。
在某些实施方式中，支架12的两侧形成有两个安装部128，两个安装部128的上表面形成安装平面121。如此，通过两个安装部128将支架12安装在无人机100的机身20，从而将安装平面121可水平地安装在无人机100的机身20上，使相机模组14可以拍摄到无人机100前方及斜向下方向的场景。
具体地，第一支架122包括本体129和设置在本体129两侧的两个安装部128，其中一个安装部128开设有卡槽126。凸块1222设置在本体129的外表面。每个安装部128开设有安装孔1282。支架12安装至无人机100的机身20时，无人机100的机身20设有安装平台22，安装部128的上表面抵靠在安装平台22，并通过紧固件1284穿设安装孔1282将安装部128固定在安装平台22。如此，第二支架123固定安装在第一支架122，第一支架122固定安装在安装平台22，相机模组14安装在容置空间124内，从而实现摄 像头组件10稳定地安装在机身20，安装过程方便快捷，安装平台22相对于无人机100的机身20的角度固定，从而使得相机模组14的光轴L相对于无人机100机身20的角度固定。
可以理解，在其它实施方式中，摄像头组件10也可通过其它安装方式，例如，焊接或卡合的方式，安装在无人机100的机身20。
请参阅图6-图9，本发明实施方式的一种无人机100包括机身20和上述任一实施方式的摄像头组件10，支架12通过安装平面121安装在机身20。
本发明实施方式的无人机100，安装平面121可水平地安装在无人机100的机身20上，这样相机模组14可以拍摄到无人机100前方及斜向下方向的场景，拍摄方便，扩大了摄像头组件10的拍摄视角，从而扩大了无人机100航拍的应用场景。
具体地，机身20的前侧开设有与柱状部1224配合的机身通孔24，柱状部1224穿设机身通孔24。如此，一方面可以使摄像头组件10的安装位置更稳定，另一方面也可使相机模组拍14摄到的视角更大。
无人机100包括设置在机身20的机臂30和设置在机臂30上的动力组件(图未示)，动力组件为无人机100飞行提供动力。
在某些实施方式中，无人机100包括下视摄像头(图未示)，下视摄像头安装在机身20的下侧，摄像头组件10安装在机身20的前侧。如此，摄像头组件10和下视摄像头配合，使得无人机100的拍摄视角大，航拍效果更好。
