具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的一种键盘进行详细描述。
图1为本公开实施例提供的一种键盘的结构示意图，如图1所示，该键盘包括：键盘本体1、至少一个物理按键2、至少一个虚拟按键投影装置3和点击检测装置9。
其中，物理按键2设置在键盘本体1上；虚拟按键投影装置3与键 盘本体1相连，虚拟按键投影装置3配置为通过投影方式在键盘本体1之外的投影区域4呈现出至少一个虚拟按键5的图像；点击检测装置9配置为检测投影区域内是否存在手指点击以及在检测出存在手指点击时确定手指所点击的虚拟按键。
在本公开实施例中，仅将部分按键以物理按键2的形式设置在键盘本体1上，而将另一部分按键以投影虚拟按键5的形式呈现，由于键盘本体1上需要承载物理按键2数减少且虚拟按键投影装置3所占用空间相对较小，因此键盘本体1的尺寸可有效减小，即键盘的整体尺寸减小。与此同时，未以物理按键2形式呈现的按键能够以虚拟按键5的形式呈现，因此键盘的输入功能不会出现损失。
在本公开实施例中，将部分按键以物理按键2形式设置在键盘本体1上，可使得本公开所提供的键盘也具有传统键盘的真实点击体验感。物理按键2可以为薄膜式按键、机械轴式按键等，本公开对物理按键2的具体结构不作限定。
键盘在使用时一般会放置于支撑面上，例如桌面。键盘的投影区域4可以为支撑面上位于键盘本体1所处区域附近的区域，虚拟按键投影装置3所投影的虚拟按键5的图像位于投影区域4内，投影区域4的具体位置具体位置可根据需要来进行预先设定。
在一些实施例中，可将一些使用频率较低的按键以虚拟按键5形式的呈现，例如位于功能键区的按键，一般包括“F1”～“F12”键、“Ese”键、“Print Screen键”、“Scroll Lock”键、“Pause\Break”键等；将一些使用频率较高的按键以物理按键2形式安装于键盘本体1上，例如位于打字区和数字小键盘区的按键，一般包括数字键、字母键、标点符号键、空格键以及其它一些控制键。需要说明的是，上述情况仅起到示例性作用，其不会对本公开的技术方案产生限制。在实际应用中，可根据实际需要来设定将哪些按键以物理按键2形式呈现以及将哪些按键 以虚拟按键5形式呈现。
图2为本公开实施例中虚拟按键投影装置的一种结构示意图，如图2所示，在一些实施例中，虚拟按键投影装置3包括：光源301和图像模板302；其中，图像模板302位于光源301的出光侧，图像模板302配置为具有与待呈现的虚拟按键5相匹配的透光区和除透光区之外的遮光区。图2所示情况中仅示例性给出了一个虚拟按键投影装置3包括一个光源301和一个图像模板302且投影出一个虚拟按键5--“F1”键的情况。
图3为本公开实施例中虚拟按键投影装置的另一种结构示意图，如图3所示，与图2所示情况不同，图3所示虚拟按键投影装置3中包括多个光源301，图像模板302上设置有多个透光区(一套图像模板302可以对应多个虚拟按键5)，每个透光区对应一个虚拟按键5。图3所示情况中仅示例性给出了虚拟按键投影装置3投影出多个虚拟按键5，分别为“F1”键、“F2”键、“F3”键等。
图4为本公开实施例中虚拟按键投影装置的又一种结构示意图，如图4所示，与图2和图3中所示情况不同，在图4所示情况中图像模板302配置为具有与待呈现的虚拟按键5相匹配的遮光区和除遮光区之外的透光区。在光源301的出光侧未设置图像模板302时，光源301在投影区域可投影出具有一定形状(例如圆形、矩形等)的亮区域；在光源301的出光侧设置图像模板302时，图像模板上的遮光区对部分光线形成遮挡，以在具有预设形状的亮区域内呈现虚拟按键5的图像(暗区域)。
在本公开实施例中，图像模板302的透光区或遮光区与虚拟按键相匹配的情况，均属于本公开的保护范围。
在实际应用中，可根据实际需要来设定虚拟按键投影装置3的数量以及每个虚拟按键投影装置3所投影出的虚拟按键5数量和具体按键。一般地，不同虚拟按键投影装置3所投影出的虚拟按键5不会存在交叠。
在一些实施例中，图像模板302上的透光区的形状、尺寸可调(相应地，遮光区的形状、尺寸可调)，即在不同时刻同一虚拟按键投影装置3所投影出的虚拟按键5可以相同也可以不同。
在一些实施例中，图像模板302为光透过率调节器件。进一步地，图像模板302包括：液晶面板。液晶面板包括液晶盒以及分别位于液晶盒相对侧的第一偏振片和第二偏振片，液晶盒一般包括阵列基板、对置基板以及位于阵列基板、对置基板之间的液晶层。通过控制液晶盒内不同区域内液晶分子的偏转，从而可对液晶盒内不同区域的透光率进行控制，从而实现对液晶面板上透光区位置的控制。在实际应用中，液晶面板上透光区可以调节变化，仅需要增加简单的处理器以及存储投影图像数据。
需要说明的是，在一些实施例中液晶盒中的对置基板为彩膜基板，此时通过液晶面板所投影出的虚拟按键5可以为彩色图案，以实现更为丰富的投射。
在一些实施例中，虚拟按键投影装置3还包括：准直光学元件(未示出)；准直光学元件位于光源301和图像模板302之间或位于图像模板302背向光源301的一侧，准直光学元件配置为对光线进行准直处理。通过设置准直光学元件，可有效提升投影效果。
当然，本公开实施例中的虚拟按键投影装置3并不限于上述结构，该虚拟按键投影装置3还可以采用其他方式来实现。例如，虚拟按键投影装置3具体为激光投影装置、硅基液晶投影装置或数字反射镜投影装置，这些投影装置体积较小、便于集成。
需要说明的是，激光投影装置、硅基液晶投影装置或数字反射镜投影装置属于本领域常规装置，其具体结构和投影原理此处不再赘述；然而，将激光投影装置、硅基液晶投影装置或数字反射镜投影应用至键盘中以呈现虚拟按键5，其不属于本领域的常规技术。
在一些实施例中，虚拟按键投影装置3配置有开关单元，开关单元用于控制虚拟按键投影装置3进行工作或不工作。即，用户可根据实际需要来对各虚拟按键投影装置3的工作状态进行控制。例如，对于一些使用率极低的虚拟按键5，可让相应的虚拟按键投影装置3处于不工作状态，仅在需要使用时通过开关单元控制相应的虚拟按键投影装置3切换至工作状态，从而能有效降低键盘的整体功耗。
图5为本公开实施例中点击检测装置的一种结构示意图，如图5所示，在一些实施例中，点击检测装置9包括：图像获取单元901a；其中，图像获取单元901a配置为连续获取投影区域4的图像，以供处理器902a根据图像获取单元901a获取的投影区域4的图像识别出手指所点击的虚拟按键5。具体地，处理器902a可基于图像处理技术来捕获到手指与相应区域的某个虚拟按键5的接触点击。
作为一个示例，可以先通过图像来识别出是否存在手指处于下压状态(检测是否存在手指进行点击操作)，在检测到存在手指进行点击操作时提取出该手指所处区域内的虚拟按键5的图像，从而识别出手指所点击的虚拟按键5。当然，本公开实施例中所采用的图像处理方法并不限于上述所示例。
在一些实施例中，键盘主体内形成空腔，处理器902a设置于该空腔内；图像获取单元901a设置于键盘主体的表面，图像获取单元901a可通过有线或无线的方式与处理器902a进行数据传输。
图6为本公开过实施例中2个图像获取单元在键盘本体上的分布示意图，如图6所示，在一些实施例中，图像获取单元901a的数量为2个，2个图像获取单元901a位于键盘本体1上的不同位置。以图7中所示情况为例，2个图像获取单元901a分别位于键盘本体1上左、右两个不同位置。2个图像获取单元901a各自将所获取到的投影区域4的图像传输至处理器902a，处理器902a执行处理操作解析到手指所点击的虚 拟按键5的信息。2个图像获取单元901a的设计，可以更容易的对手指点击位置进行定位以及提高检测精准度。
在一些实施例中，图像获取单元901a可以为摄像头、光学传感器等具有图像获取功能的结构或设备。
图7为本公开实施例中点击检测装置的另一种结构示意图，如图7所示，在一些实施例中点击检测装置9包括：定位单元901b。其中，定位单元901b配置位于获取手指在投影区域4内的点击位置，以供处理器902b根据点击位置和各虚拟按键5的投影位置确定手指所点击的虚拟按键5。
在任意时刻键盘的投影区域4内所呈现的各虚拟按键5和位置都是已知的，故仅需确定手指在投影区域4内的点击位置，即可确定出手指所点击的虚拟按键5。
本公开实施例中的定位单元901b具体可以为光学定位设备(例如激光定位设备)、无线电定位设备(例如，声波定位设备、设备定位设备)等。本公开的技术方案对定位单元901b的具体结构和定位原理不作限定。
需要说明的是，图5和图7所示点击检测装置9的具体结构仅起到示例性作用，其不会对本公开的技术方案产生限制。当然，本公开实施例中的点击检测装置9还可采用现有投影键盘的点击检测原理来对手指所点击的虚拟按键5进行检测识别，此处不再赘述。
在一些实施例中，键盘还包括：提示装置(未示出)，提示装置设置于键盘本体1上，提示装置配置为在点击检测装置9检测到手指点击虚拟按键5时采用预设提示方式提醒用户点击成功。
在一些实施例中，预设提示方式包括以下所列方式中的一种或多种：1)发出声音提示；2)发出光闪烁提示；3)提高被点击虚拟按键的显示亮度；4)降低与被点击虚拟按键相邻的求他虚拟按键的亮度；5)发出 振动提示。
当然，上述提示装置也可以配置为手指点击物理按键2时采用预设提示方式提醒用户点击成功，这种方式可以在一定程度上提升用户的体验感。
在一些实施例中，键盘配置为可变形。其中，键盘“可变形”具体是指键盘上的至少部分部件可折叠、可运动(例如伸缩运动、旋转运动)等。下面将结合附图进行详细描述。
图8为图1所示键盘的一种右视图，如图8所示，在一些实施例中，键盘内设置有可运动变形的结构。具体地，键盘不但包括上述键盘本体1、物理按键2和虚拟按键投影装置3，还包括至少一个可运动的支撑连接件6。
其中，支撑连接件6的一端与键盘本体1相连，支撑连接件6的另一端与至少一个虚拟按键投影装置3相连。支撑连接件6起到支撑虚拟按键投影装置3以及将键盘主体与虚拟按键投影装置3进行连接的作用。
在一些实施例中，支撑连接件6的一端与键盘本体1的边缘区域相连，边缘区域包括：键盘本体1上设置有物理按键2一侧表面的周边区域(参见下方图9A和图9B中所示情况)以及键盘本体1的侧面(未给出相应附图)。
在一些实施例中，当键盘内设置有上述可运动的支持连接件时，虚拟按键包括：F1键、F2键、F3键、F4键、F5键、F6键、F7键、F8键、F9键、F10键、F11键、F12键中的至少之一。
图9A为支撑连接件6放置于容纳槽7内的一种俯视示意图，图9B为支撑连接件6移出至容纳槽7外的一种俯视示意图，如图9A和图9B所示，在一些实施例中，键盘本体1的边缘区域设置有与支撑连接件6相对应的容纳槽7，支撑连接件6配置为能够放置于对应的容纳槽7内且能够从对应的容纳槽7内移出。
作为一种可选实施方案，继续参见图9A和图9B所示，容纳槽7内设置有第一转动轴8，支撑连接件6的一端与第一转动轴8相连且能够绕第一转动轴8进行转动；通过转动第一转动轴8可实现支撑连接件6从容纳槽7内移出或放置于容纳槽7内。
作为另一种可选实施方案，支撑连接件6与滑轨相连且能够沿滑轨进行运动以从容纳槽7内伸出或缩回。此种情况未给出相应附图。
在一些实施例中，可在容纳槽7内设置弹力结构(未示出)和限位结构(未示出)，同时在容纳槽7外设置与限位结构相连的机械按钮(未示出)。在支撑连接件6放置于容纳槽7内时，支撑连接件6挤压弹力结构且限位结构限制支撑连接件6向容纳槽7外运动；当需要将支撑连接件6移出时，通过按压机械按钮，使得限位结构取消限位功能，在弹力结构的弹力作用下，支撑连接件6通过旋转运动、直线运动或其他方式从容纳槽7内移出。
当然，也可以无需设置上述弹力结构、限位结构和机械按钮，支撑连接件6的收纳或移出采用手动控制。
需要说明的是，本公开实施例中容纳槽7的位置并不限于附图中所示键盘主体上承载有物理按键2的一侧，容纳槽7还可以设于其他位置，例如键盘主体的侧面。
图10为本公开实施例中键盘本体的一种结构示意图，如图10所示，在一些实施例中，键盘内设置有可折叠变形的结构。具体地，键盘本体1配置为可折叠变形，以使得键盘在未被使用时所占用的空间更小，便于携带。
在一些实施例中，键盘本体1包括：旋转连接部101和至少一个转动部102。其中，转动部102通过对应的第二转动轴103与旋转连接部101相连，转动部102绕第二转动轴103进行转动以实现折叠变形；物理按键2和点击检测装置9设置在转动部102上。在图10所示方案中， 对于虚拟按键投影装置的设置位置不作限制。
在一些实施例中，当键盘本体1包括上述旋转连接部101和转动部102时，物理按键包括：F1键、F2键、F3键、F4键、F5键、F6键、F7键、F8键、F9键、F10键、F11键、F12键中的至少之一。
