具体实施方式
如图1所示，在投影装置的优选实施例中，该投影装置包括壳体100，用于接收手机视频信号的视频输入模块101，用于对手机视频信号进行处理的视频处理模块102，用于将被处理后的视频信号投射出来的投影模块200；投影模块200包括至少一块设置在壳体100上的反射镜，投影模块200最终通过反射镜将图像投射出来。当手机与投影装置建立通信连接之后，投影装置通过视频输入模块101接受手机的视频信号，而后通过视频处理模块102对手机视频信号进行预处理，最终通过投影模块200和反射镜将处理完成的视频信号投射出去。在本发明的优选实施例中，反射镜采用的是非球面反射镜400。非球面反射镜400能够消除投影影像发生的梯形畸变。
图2是本发明投影装置的侧视图，在上述投影装置中，投影模块200通常包括光学系统、散热结构以及电路这三个主要的部分，本发明中提到的投影模块200属于现有公知技术，在此不再叙述。通过该非球面反射镜400能够很好地消除由投影模块200产生的梯形畸变，使投影模块200投射出来的影像呈矩形，从而使影像更为清晰，使用也更加方便。且为达到最佳的效果，还可以对非球面反射镜400与投影模块200中光学镜头进行结构优化，且经过优化的非球面反射镜400的工作距离可以保持在75-150mm，投射比则保持在0.4：1（投射距离：投射画面宽度）以下。
非球面反射镜400可以直接固定在壳体100上，其固定的位置应使得投影模块200投射的影响能够经由非球面反射镜400修正。也可以通过支架结构300与壳体100连接，该支架结构300使得该非球面反射镜400能够在反射影像，也就是工作时处于伸展的位置，同时又能够在非球面反射镜400不工作时，可收缩或隐藏于壳体的隐藏位置。这种支架结构300有利于设备的小型化，使得整个投影装置能够被作为一种附件被运用到便携式电子设备当中
优选地，上述支架结构300包括轴线与投影模块200的光轴垂直的转轴301、以及设置在转轴301上的支架，非球面反射镜400即设于该支架上。非球面反射镜400可绕转轴301转动。支架结构300中的转轴301能够便于非球面反射镜400的收起和打开，上述壳体100的隐藏位置在此可被理解为壳体100的侧边，也就是非球面反射镜400被收起时，其反射面能够大致与壳体100的外侧壁贴合的位置。
如图3所示，在该实施例中，支架又可被分为第一支架302、以及与第一支架302的侧边连接的第二支架303，且第一支架302与第二支架303大致垂直，使得支架的横截面呈L形。截面呈L形的支架使得非球面反射镜400在收起的时候能够更好地与壳体100的侧壁贴合，因此也更有利于设备的小型化。 进一步地，还可以使第一支架302的其中一条侧边与第二支架302的其中一条侧边铰接，这样，在非球面反射镜400被收起后，还能够进一步调整第一支架302与第二支架303之间的角度，使非球面反射镜400能与壳体100的外侧壁更好地贴合。
除了上述转轴式的支架结构外，支架结构300还可以有更多地变换形式，例如支架结构300可以采用与壳体100连接的支板，该支板设有安装面，为了保证安装在支板上的非球面反射镜400能够反射由投影模块200投射的影响，使得支板安装面与投影模块200光轴的夹角不小于90度，然后将非球面反射镜400通过滑移结构可滑动地设置在支架的安装面上。这样，使用时，只需将非球面反射镜400抽出，而不使用时将非球面反射镜400插入即可。如图4所示，在本发明的优选实施例中，该滑移结构采用的是对称设置在安装面相对两侧边上的L形槽304。可以理解的，滑移机构也可以采用其他更为复杂的结构。在进行安装时，将非球面反射镜400相对的两侧边分别插入到L形槽304（如图5所示）中，即可实现在安装面上来回自由滑动。这种滑移结构使得非球面反射镜400的投射区域可被适当调整。
此外，作为滑移结构的延伸，还可以将支架结构300设计成类似于抽屉式的结构。在这种方案中，需要在壳体100的顶部开设容置腔，支架结构300为安装架，将非球面反射镜400固定在安装架上，然后整体插入到容置腔中，在使用时将安装架抽出，不使用时将安装架推回容置腔内，这样就使得非球面反射镜400能够完全隐藏在壳体100内，更加有利于设备的小型化。同理，作为转轴式支架结构的延伸，还可以将支架结构设计成竖直转轴和安装板的形式，在该方案中，可在壳体100的顶部竖直设置一根转轴，该转轴的轴线与投影模块200的光轴平行，安装板可绕转轴转动，使用时，旋转安装板，使固定在安装板上的非球面反射镜400位于壳体100之外处于伸展位置，而不使用时，将安装板转回壳体100顶侧即可。
优选地，如图6所示，该投影装置还可以包括设置在壳体100内的投影互动模块（图中未用标号示出）。当投影装置具备投影互动模块时，投影装置可以与便携式电子设备（例如，手机）整合，将便携式电子设备屏幕上的影像投影到桌面或者其他地方。该投影互动模块属于一种比较成熟的技术，它通常包括信号处理器（图中未用标号示出）、与信号处理器通信连接的红外感应器101和光电传感器102。红外感应器101能够利用红外激光形成一个与桌面平行，并且非常贴近桌面的扇形传感面，当手指触碰桌面时会遮挡住红外激光，光电传感器102（COMOS/CCD相机）将抓取包含反光点的图像，由信号处理器计算出反光位置，在经过投影视场与传感器视场的变换映射得到手指在投影画面上的逻辑触碰位置，进一步反馈给上位机做出人机互动的相应。
此外，如图7所示，该投影装置还可以包括有设置在壳体100内的、与投影模块200连接的3D深度相机103。3D深度相机103也属于一种比较成熟的技术，应用到本发明中时，原理如下：当投影模块200通过非球面反射镜400将影像投到桌面上，目标物体（例如：手）按照事先设计好的行为准则或者自学习的行为规则做出特定的动作，此时由3D深度相机获取手的位置变化以及3D姿态等信息，然后将该信息传递给信号处理器，从而输出互动效果。在本发明一种手机投影装置的具体实施例中，该手机投影装置除了包括上述所述的投影装置之外，还包括集成在壳体内、且与视频输入模块连接的手机模块。手机模块与投影装置之间的通信连接可以通过HDMI,MHL，AV或无线等连接方式，使得手机模块显示屏上的影像能够通过投影装置投射到桌面上。此外，还可以通过合适的结构设计，使得投影装置被竖直放置时，画面被投影到水平面（例如，桌面）上，而当投影装置被水平放置时，画面可以被投射到竖直表面（例如，屏幕或墙面）上。此时，用户的双手就可以解放出来，而不用时刻握住手机，极大地提升了用户体验。
本发明的手机投影装置中的互动模块可以实现将智能手机的触控屏转移至手机旁边的大尺寸投影互动屏幕，可以使用户实现诸如操作键盘输入或者大屏幕游戏体验的原来智能手机无法实现的功能。
以上实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据此实施，并不能限制本发明的保护范围。凡跟本发明权利要求范围所做的均等变化与修饰，均应属于本发明权利要求的涵盖范围。
