附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。
图1为根据本公开一个实施例的穿戴式投影设备的结构示意图；
图2为图1中穿戴式投影设备佩戴在手指上时的示意图；
图3为根据本公开另一实施例的穿戴式投影设备的分解示意图；
图4为根据本公开的实施例的穿戴式投影设备的局部放大示意图；
图5为根据本公开的实施例的模块示意图。
具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1所示，本公开实施例提供了一种穿戴式投影设备，包括：第一结构体1和第二结构体2，第一结构体1和第二结构体2相互活动连接，且第一结构体1和第二结构体2可以相对彼此旋转；第一结构体1和第二结构体2上分别设置有投影装置3。
例如，当第一结构体1和第二结构体2均为环状体时，两个环状体具有大致相同的中心轴线，使得第一结构体1和第二结构体2可以以上述中心轴线为轴相对彼此旋转。上述穿戴式投影设备可以为投影戒指，该投影戒指可以应用于各种应用场景。例如，如图1和图2所示，将投影戒指佩戴在手指上，旋转第一结构体1和第二结构体2，使其中一个投影装置3朝向佩戴者的手掌方向，另外一个投影装置3朝向位于佩戴者的手背方向的墙壁或者桌面。两个投影装置3可以投射相同的影像或者不同的影像，例如投向佩戴者手掌的影像为带注释的幻灯片，便于佩戴者讲解；而投向墙壁的影像为不带注释的幻灯片，内容更加直观，便于其他人观看。或者，可以将第一结构体和第二结构体上的两个投影装置调节至同一方向，其中一个投影装置向桌面投射影像，另一个投影装置向墙壁投射影像。
根据本公开的实施例的穿戴式投影设备，通过在两个可以相对旋转的结构体上分别设置投影装置，能够分别在不同的方向上投射影像，使得穿戴式投影设备的应用场景更加广泛，并且使用更加方便。
例如，如图3所示，上述第一结构体为第一环状体4，上述第二结构体为第二环状体5。
例如，上述穿戴式投影设备为投影戒指。
例如，第一环状体4的端口与第二环状体5的端口相互嵌套连接。
根据本公开的一个实施例，第一环状体4和第二环状体5相互连接的两个端口处分别设置有相互啮合的齿状结构。例如，如图3所述，在第一环状体4的下端设置有齿状结构41，在第二环状体5的上端设置有齿状结构51。在第一环状体4和第二环状体5的相对位置关系调节完成之后，相互啮合的齿状结构能够保证第一环状体4和第二环状体5不再转动，从而提高了投影时的稳定性。
根据本公开的一个实施例，第一环状体4上齿状结构的齿尖处设置有电极；第二环状体5上齿状结构的齿根处设置有电极。不论第一环状体4与第二环状体5如何转动，在转动完成之后的静止状态时，第一环状体4上齿状结构的齿尖与第二环状体5上齿状结构的齿根总具有相同的对应位置关系，因此能够保证上述两个电极上不同的触点正确对应，从而实现第一环状体4中电子元件与第二环状体5中电子元件之间的电连接。
图4为第一环状体4和第二环状体5的局部放大示意图。在图4中示出了在第一环状体4的齿状结构41的齿尖处设置有电极411，在第二环状体5的齿状结构51的齿根处设置有电极511。在所述第一环状体4的齿状结构和所述第二环状体5的齿状结构相互啮合的状态下，所述第一环状体4上齿状结构的齿尖处设置的电极411与所述第二环状体5上齿状结构的齿根处设置的电极511可以相互电连接。
例如，电池通过这两个电极实现同时给第一环状体和第二环状体上的投影装置供电；或者第一环状体4和第二环状体5分别设有电池；或者第一环状体4和第二环状体5分别配有无线充电装置，可以以无线充电的方式获得电能。
根据本公开的一个实施例，上述穿戴式投影设备还可以包括：触摸检测模块，可以检测手指对作为投影屏幕的物体的触摸动作。该触摸检测模块与投影装置配合可以在作为投影屏幕的物体上实现虚拟触控。
例如，图5示意性地示出了任一环状体的模块示意图。从图5可以看到，触摸检测模块可以与投影装置连接，以配合在作为投影屏幕的物体上实现虚拟触控。
根据本公开的一个实施例，上述触摸检测模块可以包括激光发生器和激光感应器，激光发生器产生投射于作为投影屏幕的物体的表面激光，当手指或触摸笔在具有键盘图案的作为投影屏幕的物体表面上按键操作时，激光会在手指或触摸笔上形成光斑，激光感应器感应手指或触摸笔上光斑对应于键盘图案映射的位置。激光发生器和激光感应器可以设置在上述第一环状体和第二环状体中的一个或两个上。激光发生器、激光感应器和上述的任意一个投影装置可以组成虚拟键盘投射装置，例如，投影装置投射键盘图案在手掌上，激光发生器产生投射于手掌表面的激光，如可见光或红外光，当手指或触摸笔在具有键盘图案的手掌上按键操作时，激光会在手指或触摸笔上形成光斑，激光感应器感应手指或触摸笔上的光斑对应于键盘图案映射的位置，就可以知道哪些按键被按下，从而实现虚拟键盘投射。例如，所述触摸检测模块包括激光发生器和激光感应器，所述激光发生器被配置为产生投影于作为投影屏幕的物体的表面激光，所述激光感应器被配置为通过所述激光在对投影屏幕进行操作的手指或触摸笔上产生的光斑判断手指或触摸笔的触摸位置。
例如，上述穿戴式投影设备还可以包括：无线模块，该无线模块分别与上述第一环状体上的投影装置以及第二环状体上的投影装置电连接，上述投影装置通过无线技术实现与其他设备之间的通信和/或电能连接。例如，无线模块可以设置在第一环状体上，该无线模块连接于第一环状体上齿状结构的齿尖上的电极以及第一环状体上的投影装置，第二环状体上齿状结构的齿根上的电极连接于第二环状体上的投影装置，无线模块通过这两个电极电连接至第二环状体上的投影装置。当然无线模块也可以设置在第二环状体上，类似的，无线模块通过上述齿状结构上的电极电连接至第一环状体上的投影装置。设置有无线模块的投影戒指可以通过无线技术实现投影装置与其他设备之间的通信和/或电能连接，例如直接将手机屏幕的图像输出在手掌和/或墙壁上。该无线模块还可以电连接于上述激光发生器和激光感应器，例如将手机屏幕的图像输出和按键输入都在手掌上实现。当然，也可以通过有线连接的方式实现投影装置与其他设备之间的连接。
例如，图5示意性地示出了任一环状体的模块示意图。从图5可以看到，无线模块可以与投影装置连接，以实现投影装置与其他设备之间的连接。无 线模块也可以与触摸检测模块连接，以实现触摸检测模块与其他模块或设备的通信等。
本实施例中的穿戴式投影设备，通过在两个可以旋转的结构体上分别设置投影装置，能够分别在不同的方向上投射影像，使得穿戴式投影设备的应用场景更加广泛，并且使用更加方便。另外，通过增加激光发生器和激光感应器实现虚拟键盘的投射，从而同时实现图像输出和按键输入。另外，通过无线模块实现与外部设备之间连接，使穿戴式投影设备的应用更加方便。
尽管上面以投影戒指为例进行了说明，然而，本领域的技术人员应当明白，根据本公开实施例的穿戴式投影设备不限于此，例如还可以是投影手镯、投影手表、投影眼镜等其他设备。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
本申请要求于2014年4月28日递交的中国专利申请No.201420212879.1的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
