本公开涉及电子设备技术领域，尤其是指一种投影设备。
背景技术
随着科技的高速发展，移动终端以娱乐性多样化、方便携带等优点，在人们生活中已经不可或缺。目前在移动终端使用时，经常碰到需要将移动终端所显示图像投影展示的情况。
目前相关技术一种方式为使移动终端通过数据线与投影装置连接，或者直接在移动终端上集成设置投影单元，以满足移动终端上图像的投影展示的使用需求。然而，第一种使移动终端通过数据线与投影装置连接的方式，无法满足部分使用者希望移动终端与投影功能相集成，以随时随地使用投影功能的需求，而第二种直接在移动终端上集成设置投影单元的方式，虽然能够满足移动终端与投影功能的集成要求，但对于另一部分使用者来说，由于投影功能的使用率较低，而且增加投影单元造成移动终端成本过高，因此该种移动终端也不能作为所选择产品。
因此，相关技术用于移动终端的投影结构和方式，不能满足人们的多种使用需求。

具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
本公开的一些实施例提供一种投影设备，所述投影设备包括：
设备本体，设置有一用于固定移动终端的卡扣结构，通过所述卡扣结构，所述移动终端包括固定于所述设备本体上的状态和与所述设备本体分离的状态；
第一数据接口，设置于所述设备本体上，所述移动终端固定于所述设备本 体上时，所述第一数据接口与所述移动终端上的第二数据接口相连接；
投影装置，固定于所述设备本体上，且与所述第一数据接口连接。
本公开的实施例所述投影设备，通过在设置有投影装置的设备本体上设置卡扣结构，移动终端通过卡扣结构能够与投影设备相连接或者分离；这样移动终端本体上不需要集成投影功能，当需要满足用户对移动终端上投影功能的集成要求时，只需要将移动终端固定至设备本体上即可，因此该种结构的投影设备，能够满足用户对移动终端的多种使用需求。
本公开的实施例所述投影设备中，所设置投影装置利用第一数据接口与移动终端上的第二数据接口之间的数据传输，使移动终端所显示输出画面和/或用于移动终端数据输入的画面(如键盘显示画面)投影显示。当使移动终端所显示输出画面投影显示时，用户通过画面投影可以观看到移动终端所显示内容；当用于移动终端数据输入的画面投影显示，如显示一键盘时，通过所显示键盘作为输入界面，用于移动终端上数据的输入。
因此，本公开的实施例所述投影设备，可以实现移动终端的多种投影方式，使用方便，且能够满足用户的多种投影需求。
具体地，本公开的一些实施例所述投影设备中，所述设备本体包括：支撑部分和与所述支撑部分通过转动结构相连接的投影部分；通过所述转动结构，所述投影部分相对于所述支撑部分的倾斜角度变化；
所述投影装置包括投影图像形成元件和投影图像输出元件，其中所述投影图像形成元件固定于所述支撑部分上，所述投影图像输出元件固定于所述投影部分上。
上述结构的设影设备中，通过将投影图像输出元件设置于投影部分上，且投影部分相对于支撑部分的倾斜角度变化，实现投影装置的投影角度可调，以满足多种投影角度需求。
图1a为本公开的一些实施例所述投影设备的外观结构示意图。结合图1a，本公开的一些实施例中，投影设备包括设备本体100，设备本体100包括支撑部分110和投影部分120，其中支撑部分110与投影部分120之间通过转动结构113相连接。在本公开的一些实施例中，转动结构113可以如图1b所示设置。利用支撑部分110与投影部分120之间设置的转动结构，投影部分120能够相对于支撑部分110在预设角度范围内转动，投影部分120相对于支撑部分 110的倾斜角度变化。
本领域技术人员应该能够了解用于实现投影部分120相对于支撑部分110之间转动的转动结构的具体结构方式，且该转动结构的具体结构并非为本公开的研究重点，在此不作详细描述。
参阅图1a，本公开的一些实施例中，支撑部分110包括底座111和连接件112，其中底座111包括形成为平面的支撑底面，用于使整个投影设备平放于一水平面上。连接件112连接于底座111与投影部分120之间，图1a中底座111形成为平板状结构，连接件112形成为弯曲的条状，所展示形状仅用于说明设备本体100的结构构成，具体并不限于此。
另外，可选地，当投影设备通过底座111的支撑底面放置于一平面，且移动终端通过设备本体100上的卡扣结构固定于投影设备上时，移动终端的显示屏幕相对于支撑底面呈预设倾斜角度，例如该预设倾斜角度可以为90度，也即移动终端的显示屏幕垂直于支撑底面所固定的平面，当然不限于为90度，也可以为大于90度。通过该种设置方式，移动终端固定于投影设备上进行投影显示时，还能够使观看者同时方便地看到移动终端的显示屏幕上的显示内容。
图2a所示为移动终端200放置于图1a所示结构的投影设备上时的结构示意图。当移动终端200固定于投影设备上时，显示屏幕呈竖直状态，可以很直观地观看到显示屏幕上所显示内容。
本公开的一些实施例所述投影设备中，底座111与连接件112的内部分别具有较大容纳空间，用于设置投影装置所包括的构件。
具体地，本领域技术人员可以理解，投影装置包括投影图像形成元件，例如对于数字光处理器DLP投影仪来说，投影图像形成元件包括光源、模数解码器、内存芯片、影像处理器及数字微反射镜等。参阅图8所示投影装置的传输光路示意图，移动终端所输出的图像经模数解码器、数字信号处理器及影像处理器等处理后，转到数字微反射镜，光源所发出光束通过一高速旋转的三色透镜后，被投射到数字微反射镜1上，经数字微反射镜1反射后再经过由多个反射镜头2组成的光学系统反射后，通过投影物镜121投射而出，从而显示出对应的投影画面。
基于投影装置的上述设置结构，其中用于形成投影图像的图像形成元件，例如光源、模数解码器、内存芯片、影像处理器、数字微反射镜等设置于支撑 部分110的容纳空间内，投影图像输出元件，例如包括投影物镜和/或反射镜设置于投影部分120上。
如图1a所示，投影物镜121外露于投影部分120的一端面上，用于使投影图像投射而出。另外，具体地，本公开的一些实施例中，结合图1c，投影装置的模数解码器、内存芯片、影像处理器、数字微反射镜等图像形成元件123可以设置于底座111的容纳空间内，投影图像输出元件122可以设置于投影部分120的容纳空间内，用于投影图像光路传输的数字微反射镜头1可以设置于底座111内部的容纳空间内，用于投影图像光路传输的反射镜头2可以设置于连接件112内部的容纳空间内。
以上关于投影装置的结构仅用于举例说明，本领域技术人员应该能够了解投影装置的具体构成，且该部分并非为本公开的研究重点，在此不详细描述。
另一方面，可选地，本公开的一些实施例所述投影设备中，结合图1，支撑部分110的内部容纳空间内还可以设置有：供电装置，用于为投影装置提供电能，且当移动终端固定于投影设备上时，通过所设置的第一数据接口与移动终端上的第二数据接口相连接，供电装置也能够为所设置移动终端提供电能；音频播放装置，用于当移动终端固定于投影设备上时，通过所设置的第一数据接口与移动终端上的第二数据接口相连接，播放移动终端所输出的音频文件；语音接收装置，用于当移动终端固定于投影设备上时，通过所设置的第一数据接口与移动终端上的第二数据接口相连接，接收用户所输出的语音信息，并传输至移动终端上。
本公开的一些实施例中，所述供电装置、音频播放装置、语音接收装置可以如图1c所示设置于支撑部分110的内部容纳空间内。
所述投影设备上所加入的上述供电装置、音频播放装置和语音接收装置，能够极大地丰富投影设备的功能，构成为多种功能集成的设备，以满足用户的多种不同需求。
另一方面，结合图1a和图2a，本公开的一些实施例所述投影设备中，所设置卡扣结构包括第一插槽130。如图2b所示，所述移动终端200可以如图2b所示。当移动终端200固定于投影设备的设备本体100上时，移动终端200的第一端面的部分卡扣于第一插槽130的内部。
可选地，卡扣结构还包括与第一插槽130相对且平行设置的第二插槽，如 图2a所示，移动终端200固定于投影设备的设备本体100上时，移动终端200的与第一端面相对的第二端面的部分卡扣于第二插槽的内部，形成为如图2所示移动终端200的设置方式。如图3b所示，在本公开的一些实施例中，第一插槽130设置于底座111上，第二插槽130’可以设置于连接件112上，第二插槽130’与第一插槽130相对设置，通过第二插槽130’与第一插槽130的定位与卡固作用，移动终端200固定于设备本体100上。
另外，进一步参阅图1a与图3a，第一插槽130开设于底座111的端面1111上，且第一插槽130在底座111的端面1112(第三端面)上形成有开口1113，其中端面1112与端面1111为相连接的端面，通过穿过开口并朝向第一插槽130的与端面1112相对的端面推动移动终端200移动，能够使移动终端200插设于第一插槽130的内部。可选地，第二插槽130’在与开口1113的同侧也设置有开口，使得移动终端200在通过开口1113插入于第一插槽130中时，同时能够插入于第二插槽中。在本公开的一些实施例中，第二插槽130’可以如图3c所示设置。
本公开的一些实施例的另一方面，投影设备上用于与移动终端的第二数据接口相连接的第一数据接口设置于第一插槽130的底部，移动终端200的卡扣于第一插槽130内部的第一端面上设置有第二数据接口，当移动终端200的第一端面卡扣于第一插槽130的内部时，第一数据接口与第二数据接口对位连接。
可选地，第一数据接口可移动地设置于设备本体100上，当移动终端200与设备本体100分离时，第一数据接口位于第一位置，远离移动终端200固定于设备本体100上时第二数据接口的设置位置；移动终端200固定于设备本体100上时，第一数据接口位于第二位置，与第二数据接口相连接。
可选地，设备本体100上还设置有触控按钮，触控按钮通过驱动结构与第一数据接口连接；其中移动终端200固定于设备本体上时，抵压触控按钮，触控按钮触发驱动结构动作，带动第一数据接口从第一位置移动至第二位置。
本公开的一些实施例中，触控按钮设置于第一插槽130的内部，如图4所示为第一插槽130、触控按钮140与第一数据接口150之间位置关系的结构示意图。结合图4和图2a，触控按钮140位于远离第一插槽130上对应用于插入移动终端的开口一侧，且第一数据接口150能够上下移动地设置于第一插槽130的底部，且在第一插槽130的底部设置有一凹槽，当移动终端200未插设 于第一插槽130的内部时，第一数据接口150位于所述凹槽(第一位置)中，当移动终端200从第一插槽130上对应用于插入移动终端的开口1113插入，朝触控按钮140移动时，由于第一数据接口150设置于凹槽的内部，从而不至于影响插入过程；当移动终端200抵压触控按钮140时，触控按钮触发驱动结构动作，带动第一数据接口150向上移动，从凹槽中伸出，此时移动终端200上第二数据接口的位置恰好与第一数据接口150的位置相对，上移的第一数据接口150与移动终端上的第二数据接口相对接，移动至第二位置，实现第一数据接口150与第二数据接口之间的连接。
利用触控按钮140与第一数据接口150之间的连动动作，使得移动终端插入过程能够顺利完成。
图5a与图5b为用于实现触控按钮140与第一数据接口之间的连动动作的驱动结构的一些实施例的示意图。
具体地，驱动结构的第一种实现结构包括：与触控按钮140连接的第一弹性支撑结构161、与第一数据接口150连接的第二弹性支撑结构162和连接于第一弹性支撑结构161、第二弹性支撑结构162之间的支杆结构163。
其中，第一弹性支撑结构161和第二弹性支撑结构162可以分别为弹簧，当然并不限于为弹簧，只要能够起到弹性支撑作用即可。另外支杆结构163通过一支撑点支撑，构成为杠杆结构形式，两端分别与第一弹性支撑结构161和第二弹性支撑结构162相连接。
采用上述设置方式，当移动终端未插设于第一插槽130中时，第一弹性支撑结构161和第二弹性支撑结构162分别处于自然伸缩状态，此时触控按钮140在第一插槽130中凸出设置，而第一数据接口150处于第一位置，也即设置于第一插槽130底部的凹槽内部，如图5a所示；当移动终端从第一插槽130上对应用于插入移动终端的开口插入，朝触控按钮140移动，且当抵压触控按钮140时，第一弹性支撑结构161受压，利用支杆结构163的杠杆作用原理，第二弹性支撑结构162受到向上升作用力而被弹起，如图5b所示，驱动第一数据接口150上移至与移动终端上的第二数据接口相连接，实现数据接口的对位连接。
图6a与图6b为用于实现触控按钮140与第一数据接口之间的连动动作的驱动结构的一些实施例的示意图。
具体地，驱动结构的第二种实现结构包括：与触控按钮140连接的第一气囊171、与第一数据接口150连接的第二气囊172和分别连通于第一气囊171与第二气囊172的管路173。
通过驱动结构的上述设置方式，当移动终端未插设于第一插槽130中时，第一气囊171、第二气囊172和管路173内部的气压压强处于平衡状态，且第二气囊172处于自然状态，使第一数据接口150处于第一位置，也即设置于第一插槽130底部的凹槽内部，而第一气囊171也处于自然状态，使触控按钮140在第一插槽130中凸出设置，如图6a所示；当移动终端从第一插槽130上对应用于插入移动终端的开口插入，朝触控按钮140移动，且当抵压触控按钮140时，第一气囊171被挤压，管路173内部的压强增加，此时第二气囊172被加压充气而膨胀，从而使第一数据接口150被弹起，如图6b所示，第一数据接口150上移至与移动终端上的第二数据接口相连接，实现数据接口的对位连接。
图7a为本公开一些实施例的用于实现触控按钮140与第一数据接口之间的连动动作的驱动结构的示意图。
具体地，驱动结构的第三种实现结构包括：与触控按钮140连接的压力传感器、与压力传感器电连接的延时电路和与延时电路连接的动作部件180，其中动作部件180与第一数据接口150连接。
在本公开的一些实施例中，压力传感器和延时电路可以如图7b所示设置。
上述的驱动结构中，压力传感器可以设置于触控按钮140上，当移动终端未插设于第一插槽130中时，第一数据接口150处于第一位置，也即设置于第一插槽130底部的凹槽内部，而触控按钮140在第一插槽130中凸出设置；当移动终端从第一插槽130上对应用于插入移动终端的开口插入，朝触控按钮140移动，且抵压触控按钮140时，触控按钮140上的压力传感器根据压力生成预设的触发信号，延时电路接收压力传感器发送的触发信号后，在预设时间后生成控制信号发送至动作部件180，使动作部件180带动第一数据接口150动作而向上弹起，第一数据接口150上移至与移动终端上的第二数据接口相连接，实现数据接口的对位连接。
另外，用于驱动第一数据接口150向上弹起的动作部件180的结构可以有多种，如可以包括弹簧、电磁感应线圈等，通过带电吸附第一数据接口150、放电使第一数据接口150脱离吸附向上弹起的方式，实现第一数据接口150在 第一位置和第二位置之间移动。
可选地，本公开的一些实施例的投影设备中，所设置投影装置包括用于投影输出移动终端的显示屏幕上所显示图像的第一投影结构和用于投影显示键盘的第二投影结构。
其中第一投影结构和第二投影结构分别包括投影图像形成元件和投影图像输出元件，也即在如图1所示的设备本体100上，支撑部分110上设置分别对应第一投影结构和第二投影结构的投影图像形成元件，投影部分120上设置分别对应第一投影结构和第二投影结构的投影图像输出元件。利用第一投影结构和第二投影结构，移动终端的显示屏幕上所显示图像和键盘图像投影可以同时显示，使用者可以通过投影方式观看移动终端的显示屏幕上所显示图像，并同时通过投影显示的键盘向移动终端上输入数据，以方便使用。
可选地，为配合实现通过投影键盘图像向移动终端输入数据的功能，本公开所述投影设备还包括摄像头，以用于拍摄用户通过投影键盘图像输入数据时的图像，从而进行分析判断用户所输入内容。
可选地，设备本体的投影部分包括两个部分，分别设置第一投影结构和第二投影结构的投影图像输出元件，也即将上述两个部分的投影图像朝不同方向投影，如将移动终端的显示屏幕上所显示图像向下投影至墙面，将用于数据输入的键盘图像投影向下投影至桌面，以方便不同应用。
另外，本领域技术人员应该能够了解投影装置用于将移动终端的显示屏幕上所显示图像投影显示以及投影显示键盘图像，并通过投影显示键盘图像进入数据输入的具体方式，且该部分并非为本公开的研究重点，在此不详细描述。
本公开的实施例所述投影设备，可以应用于手机和PAD等移动终端。
利用上述结构的投影设备，能够将手机或PAD等移动终端插入设备本体上实现投影功能，不使用投影功能时可直接与投影设备相分离，以方便多种不同使用需求；另外，在卡扣移动终端的插槽内设置可移动地数据接口与触控按钮，能够方便移动终端与设备本体的插入和分离过程，并能够保证与移动终端之间的数据传输；进一步地，该投影设备不但能够实现移动终端上所显示图像的投影显示，还能够投影显示键盘图像，以用于移动终端的数据输入，从而满足用户的多种不同使用需求。
以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技 术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
