可以注意的是，这里所使用的术语仅是为了描述实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还可以理解的是，当在本说明书中使用术语“包含”、或“包括”、或“包含”和“包括”时，其指明存在特征、步骤、操作、器件和组件中的任意一个或它们的组合。
除非另外说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本公开的权利要求范围。同时，可以明白，为了便于描述，附图中所示出的不同部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但 在适当情况下，所述技术、方法和设备可以被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何值可以被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。可以注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行讨论。
在本公开实施例的描述中，可以理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本公开实施例和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本公开权利要求范围的限制；方位词“内、外”是指相对于部件本身的轮廓的内外。
可以理解的是，为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。可以理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，可以说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本公开权利要求范围的限制。
本公开实施例提供了一种投影仪，能够使投影仪可靠地承载手持移动终端。
可以说明的是，本申请中所指的手持移动终端可以是手机、平板电脑、电子书手持终端等。
如图1至图3所示，投影仪包括壳体10和移动终端支撑部20，壳体10具有安装腔体11，安装腔体11的一端具有开口12，移动终端支撑部20与壳体10连接，且移动终端支撑部20具有位于安装腔体11内的收纳位置和由开口12伸出安装腔体11的工作位置。
通过设置与投影仪的壳体10连接的移动终端支撑部20，移动终端支撑部20具有位于壳体10的安装腔体11内的收纳位置和由开口12伸出安装腔体11的工作位置。这样，移动终端支撑部20能够作为手持移动终端的承载体，使投影仪具有承载手持移动终端的功能，方便了用户的使用，提高了投影仪的使用便捷性，不仅如此，当用户不需要放置手持移动终端时，移动终端支撑部20位于安装腔体11内，从而有效地利用了投影仪的壳体10内的空间，避免了增大投影仪的整体体积，提高了投影仪的实用性。
如图2和图3所示，移动终端支撑部20可以包括滑移底座21和支撑结构22，滑移底座21与壳体10滑动连接，支撑结构22可枢转地设置在滑移底座21上，支撑结构22具有初始位置和相对于滑移底座21转动后的支撑位置。
由于移动终端支撑部20包括滑移底座21，滑移底座21与壳体10滑动连接，这样，滑移底座21能够伸出安装腔体11或退入安装腔体11，从而实现了移动终端支撑部20在收纳位置和工作位置之间转换，方便了用户的使用。
由于移动终端支撑部20包括支撑结构22，支撑结构22可枢转地设置在滑移底座21上，支撑结构22具有初始位置和相对于滑移底座21转动后的支撑位置。这样，用户通过旋转滑移底座21至一定角度，用户便可以将手持移动终端放置到支撑结构22上便能够方便地对手持移动终端进行操作，从而解放了双手，而且能够使用投影仪为手持移动终端进行充电，维持手持移动终端的续用功能，进而提高了投影仪的功能多样化。
如图2、图3和图5所示，移动终端支撑部20还可以包括连接座23，支撑结构22通过连接座23与滑移底座21可枢转地连接。这样，提高了支撑结构22与滑移底座21之间连接的稳定性。
如图5所示，连接座23可以为两个，两个连接座23相对设置且位于滑 移底座21的长度方向的第一端。
如图2至图4所示，支撑结构22可以呈折弯板状，支撑结构22可以包括背板221和底板222，背板221和底板222之间形成用于支撑移动终端的支撑空间223。这样，不仅保证了支撑结构22能够稳定地对手持移动终端进行支撑，而且降低了支撑结构22的结构复杂度，便于对支撑结构22进行加工制造，降低了投影仪的整体成本。
可选地，背板221和底板222可以垂直地设置，这样，当移动终端支撑部20处于收纳位置时，支撑结构22处于初始位置，且底板222能够有效地遮挡开口12，避免灰尘或杂物进入到安装腔体11而影响移动终端支撑部20的滑动，从而提高了投影仪的使用可靠性。
可选地，当支撑结构22处于初始位置时，背板221与水平方向的夹角可以为0度，当支撑结构22相对于滑移底座21旋转后，背板221与水平方向之间的夹角可以在0度到90度之间变化。可以说明的是，支撑结构22的与连接座23接触的铰接点可以位于背板221和底板222之间的折弯处，如图4所示，沿背板221和底板222之间的折弯处的长度方向的支撑结构22的两侧可以开设有定位安装孔227，连接座23上可以具有与定位安装孔227配合的定位安装凸起。
如图3和图5所示，滑移底座21上可以开设有线路安装槽211，底板222上可以开设有与线路安装槽211连通的安装缺口224。这样，通过线路安装槽211和安装缺口224能够将投影仪的充电结构隐蔽安装，避免线路杂乱无章，既保证了投影仪具有对手持移动终端稳定地充电功能，还能够提高投影仪的整体美观性。
可以说明的是，投影仪还可以包括主板结构、充电终端结构和充电线路，主板结构设置在壳体10内，充电终端结构设置在安装缺口224处并凸出于底板222的朝向支撑空间223的表面设置，充电线路设置在线路安装槽211内，充电终端结构通过充电线路与主板结构电连接。这样，当用户将手持移动终端放置在支撑结构22上时，通过将手持移动终端与充电终端结构连接，便能够使手持移动终端通过充电线路与主板结构连通，从而达到为手持移动终端充电的目的，提高了投影仪的实用性。
如图4所示，安装缺口224可以包括相连通的安装段2241和过渡段2242，其中，充电终端结构可以设置在安装段2241处，充电线路可以通过过渡段2242与充电终端结构连接。
可选地，充电线路可以为FPC线。充电终端结构可以为USB充电接口。
如图2和图3所示，移动终端支撑部20还可以包括限位座24和连杆组件25，支撑结构22可以通过连杆组件25与限位座24连接。这样，限位座24和连杆组件25的配合作用不仅能够有效地限制支撑结构22的旋转角度，而且通过连杆组件25还能够起到对支撑结构22有效地支撑作用，保证了手持移动终端位于支撑结构22的稳定性。
如图2、图3和图5所示，限位座24可以为两个，两个限位座24相对设置且位于在滑移底座21的长度方向的第二端，两个限位座24的相对的表面上均可以开设有滑移槽241。连杆组件25可以包括滑动杆251和推杆252，滑动杆251的两端分别滑动设置在两个滑移槽241内，推杆252的第一端与滑动杆251枢转连接，推杆252的第二端与支撑结构22枢转连接。这样，滑动杆251沿着滑移槽241的长度方向滑动，保证了连杆组件25与两个限位座24之间的连接稳定性。且滑动杆251的滑动能够带动推杆252运动，从而使推杆252为支撑结构22提供可靠的推力或者拉力，保证了支撑结构22顺利地与滑移底座21发生枢转运动，从而使支撑结构22稳定地在初始位置和支撑位置之间切换。
在本公开的一个未图示的可选实施例中，滑移底座21的靠近限位座24一侧的端面上可以设置有限位凸起，限位凸起可以随滑移底座21运动并止挡在壳体10的开口12处以防止移动终端支撑部20由安装腔体11滑脱。
可选地，滑移底座21、连接座23和限位座24可以一体加工成型，这样有效地降低了移动终端支撑部20的整体加工制造难度。
如图7和图8所示，滑动杆251的两端均可以开设有安装孔253，连杆组件25还可以包括限位弹簧254和定位球255，定位球255沿安装孔253延伸方向可移动地设置在安装孔253处，限位弹簧254抵接在安装孔253的底壁与定位球255之间。这样，保证了定位球255能够沿着安装孔253的孔深度方向运动，且限位弹簧254处于被定位球255压缩的压缩状态，从而限位 弹簧254为定位球255提供了可靠的弹性支撑力。
如图7和图8所示，滑动杆251可以包括两个杆体段，两个杆体段之间通过第一枢接轴257连接，如图9所示，推杆252的与滑动杆251连接的一端可以具有与第一枢接轴257配合的第一枢接孔258，这样，实现了推杆252与滑动杆251之间的枢转连接。
如图3、图4和图9所示，推杆252的与支撑结构22连接的一端可以具有第二枢转轴259，背板221远离底板222的一端可以具有卡接缺口226，卡接缺口226处可以具有与第二枢转轴259配合的第二枢接孔，这样，不仅实现了推杆252与支撑结构22之间的枢转连接，而且使推杆252对支撑结构22产生尽可能大的扭矩。
如图8所示，移动终端支撑部20还可以包括阻尼弹簧27，阻尼弹簧27设置在推杆252与支撑结构22的连接处。这样，当用户拉动移动终端支撑部20而使移动终端支撑部20由收纳位置向工作位置运动的过程中，当推杆252的与支撑结构22的连接端运动出安装腔体11后，由于阻尼弹簧27的向上的夹角张力释放，从而对推杆252和支撑结构22产生一个向上的夹角张力，使得推杆252和支撑结构22以第二枢转轴259为转轴向上抬起。这时推杆252连动滑动杆251，使得原本来卡在滑移槽241的曲面段242处的定位球255受曲面段242挤压，定位球255向安装孔253内收缩，定位球255挤压限位弹簧254，使得限位弹簧254做弹性形变积累弹性支撑力，当定位球255处于相邻两曲面段242的中间位置处时，定位球255缩回到安装孔253内。定位球255当越过相邻两个曲面段242的中间位置处时，限位弹簧254可以释放弹性支撑力，推动定位球255进入下一个曲面段242内，如此重复，实现了移动终端支撑部20对支撑结构22的卡位固定功能。
如图7和图8所示，安装孔253的孔口处可以设置有止挡凸缘256，这样，止挡凸缘256能够有效地起到对定位球255的限位作用，避免定位球255脱离安装孔253。
如图11和图12所示，滑移槽241的槽底壁表面可以包括多个曲面段242，滑动杆251可以通过定位球255卡设在曲面段242处。这样，槽底壁表面呈波纹形状，定位球255受到限位弹簧254的弹性支撑力作用卡在每一个曲面 段242处，用户可以轻松地操作推杆252，推杆252带动滑动杆251，滑动杆251受到沿滑移槽241的长度方向的拉力或推力，从而定位球255便会从一个曲面段242依次向相邻的曲面段242滑动、如图12所示，定位球255在相邻的两个曲面段之间滑动时，定位球255会受到滑移槽241的槽底壁表面的挤压而向安装孔253内运动，从而定位球255会继续压缩限位弹簧254压缩，但是定位球255会始终受到限位弹簧254为其提供的朝向安装孔253的孔口处的弹性支撑力。
可选地，曲面段242可以为圆柱面的部分表面或球面的部分表面。这样，有利于曲面段242与定位球255的表面配合，减小定位球255运动的过程中与滑移槽241的槽底壁表面之间的摩擦，且更有利于曲面段242对定位球255的限位作用，从而保证了支撑结构22在旋转的过程中停止定位在特定的角度，进而更便于用户根据个人的习惯调节支撑结构22的位置，提高了投影仪的使用便捷性。
如图4所示，移动终端支撑部20还可以包括操作部26，操作部26设置在底板222的背离支撑空间223的表面上。这样，用户能够通过推拉操作部26轻松地将移动终端支撑部20拉出安装腔体11或将移动终端支撑部20推入安装腔体11。
可选地，操作部26可以为操作把手或开设在底板222上的操作缺口。
从以上的描述中，可以看出，本公开上述的实施例实现了如下技术效果：。
1、投影仪带手机支架功能，手机支架隐藏在投影仪内，方便实用；
2、用户拉出支架时，支架可以自动上抬一定角度，用户更方便放置手机；
3、本公开实施例采用滑动杆和推杆配合的方式，支撑稳固，且有自动的张开倾角，方便用户使用；
4、采用滑动杆的定位球和滑移槽的槽底壁表面配合滚动定位的方式，运行流畅，机构质感好；
5、支架可以给手机充电，使手机在和投影仪配合使用时，更方便。
可以注意的是，这里所使用的术语仅是为了描述实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还可以理解的是，当在本 说明书中使用术语“包含”、或“包括”、或“包含”和“包括”时，其指明存在特征、步骤、工作、器件和组件中任意一个或其组合。
可以说明的是，本文中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。可以理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施方式能够以除了在这里图示或描述的那些以外的顺序实施。
