在本实施例中，所述容置外壳三30侧面还设置有可对流的第一散热孔组31和第二散热孔组32；所述第一散热孔组31和第二散热孔组32分别设置于轴向环形开口33的两侧；所述动向投影仪还包括：设置于动向投影仪本体内部的扬声器和充电电池，所述第一散热孔组31和第二散热孔组32为扬声器的出声孔；所述动向投影仪可放置在桌面使用也可以固定倒挂于天花。
值得注意的是，在本实施例中，所述所述环形外壳二20沿第一环形轨道L1的横切面，所述容置外壳三30沿第二环形轨道L2的横切面为圆形，以及所述安装底座一10沿第一环形轨道L1的横切面设置为圆形，也可以根据需要设置为其他的形状。
所述环形外壳二20沿第二环形轨道L2的横切面与所述环形外壳二20沿第一环形轨道L1的横切面直径优选相同，也可以根据需要设置成不同的 直径。
其中，所述环形外壳二20沿第二环形轨道L2的横切面的直径可以小于容置外壳三30沿第二环形轨道L2的横切面的直径，所述环形外壳二20沿第一环形轨道L1的横切面的直径可以小于安装底座一10沿第一环形轨道L1的横切面的直径，即环形外壳二20可以设置成嵌入安装底座一10和容置外壳三30之间设置的凹槽，所述凹槽可以沿第一环形轨道L1和第二环形轨道L2转动。
所述环形外壳二20沿第二环形轨道L2的横切面的直径也可以设置成等于或大于容置外壳三30沿第二环形轨道L2的横切面的直径，所述环形外壳二20沿第一环形轨道L1的横切面可以设置成等于或大于安装底座一10沿第一环形轨道L1的横切面的直径。
实施例二：
图3为本发明一种动向投影仪实施例二的立体结构示意图；如图3所示，所述动向投影仪还包括：立地底座60以及可自由伸缩的支撑杆50；安装底座一10和立地底座60分别与可自由伸缩的支撑杆50的上端51和下端52连接；所述连接可以是固定连接也可以是可拆卸式连接。
其中，立地底座60可以直接放置于地面等地方，立地底座60底部直接与支撑物接触。
其中，安装底座一10底面和可自由伸缩的支撑杆50的上端51可以分别设置有磁吸，使动向投影仪本体和可自由伸缩的支撑杆50可拆卸式连接。
在本实施例中，所述可自由伸缩的支撑杆50可调节的高度范围为：0.5米＜高度≤1.8米；可根据用户视线的高度调整支撑杆50的高度，例如：当成年用户站着的时候，调整支撑杆50的高度约为1.2米—1.8米；当成年用户坐着的时候，调整支撑杆50的高度约为0.5米—1.2米；使第一摄像镜头与用户的水平视线尽量处于同一水平面，可以实时采集用户的指向性信息，用户的指向性信息可以为用户的眼动方向、头或者手势的摆动方向，由此确定用户的意向投影方向。
实施例三：
图4为本发明一种动向投影仪实施例三的立体结构示意图；如图4所示，与实施例二不同的是，所述立地底座60底面还设置有万向移动轮组61；所述立地底座60底面通过万向移动轮组61与地面等支撑物接触。
本实施例中，可根据使用环境或者用户的要求，手动或自动的通过移动万向移动轮组61对动向投影仪进行平面式移动；例如，当在面积较大的室内空间使用时，动向投影仪离用户或者投影面较远，无法准确的采集用户的指向性信息或者投影装置无法进行清洗的投影时，可手动活自动的在地面移动动向投影仪，使其处于最佳的工作位置。
综上所述，本发明采用第一摄像装置实时地追踪用户的意向投影方向， 可根据用户的意向投影方向实时地改变投影镜头和第二摄像装置的方向进行投影显示以及投影画面的校正；动向投影仪可实现高质量的智能投影显示，可应用在多种场合，给予用户不同的视觉享受和娱乐效果。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围。
