具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明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发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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，都属于本发明保护的范围。
当前，机动车日益成为人类出行必不可少的交通工具。随着机动车技术的快速发展，各种具有独特功能的汽车层出不穷。但安全始终是机动车驾驶时最重要的考量因素。现有机动车，例如汽车大都配备了导航系统，以更加方便的到达目的地。导航装置例如通常与视频、图像等在同一个显示屏显示。此外，显示屏一般设置于驾驶员视野的下方，这使得司机在诸如需要观察显示屏以获取导航信息或者其它信息时，需要暂时将视线移开汽车的前方。特别是在汽车行驶速度很快的时候，驾驶员视线短暂的移开也可能严重影响汽车的安全行驶。因此，有必要设计一种不影响机动车安全驾驶的显示系统，以在驾驶员获取例如导航信息时，保证机动车的安全行驶。
本公开的一个方面提供了一种车灯系统，包括：照明灯，被配置为发出照明光线；投影灯，被配置为将接收到的待投影信息投影到投影介质上；以及控制模块，被配置为提供所述待投影信息以及打开和关闭所述照明灯和所述投影灯。本发明通过在车灯系统中配置投影灯，可将待投影信息投影到投影介质上，提高机动车驾驶安全性。
图1为本发明实施例的车灯系统示意图。参照图1，车灯系统包括照明灯1、投影灯2以及控制模块3。如上所述，照明灯1配置为发出照明光线，投影灯2配置为将接收到的待投影信息投影到投影介质上；控制模块3配置为提供待投影信息以及打开和关闭照明灯1和投影灯2。例如，控制模块3与照明灯1和投影灯2可以为电连接，以切断和接通对照明灯1和投影灯2的供电，实现打开及关闭照明灯1和投影灯2。此外，控制模块3还用于向投影灯2提供待投影信息，例如，控制模块3与投影灯2之间可以通过数据线连接，以向投影灯2传输有关待投影信息的数据。
投影灯的功能例如与投影仪的功能类似，即能够将接收到的信息以光线的形式发出，并显示到光线照射到的地方。在不需要使用投影灯和照明灯时，需要将其关闭，本公开实施例的控制模块即具备打开和关闭照明灯及投影灯的功能。例如，控制模块中可以针对投影灯和照明灯分别设置一个开关，进而通过开关的打开和关闭控制投影灯和照明灯的开关。开关可以手动控制开启和关闭，也可以采用电磁方式控制(例如，在开关附近设置一个电磁线圈，该电磁线圈通电时，可对开关产生作用力，从而控制开关的开启和关闭)。例如，控制模块中还可以设置供电电源，例如供电电源可以为干电池或充电电池。供电电源通过上述开关接通和断开供电电路，进而控制照明灯和投影灯的开关。例如，供电电源也可以在车灯系统之外设置，例如供电电源为汽车的电瓶。
进一步的，上述控制模块可以配置触控显示屏，显示屏上包括可触控按钮。通过按压触控按钮，对应的操作信息例如打开或关闭开关的电信息传递至开关，例如开关通过电磁力实现与操作信息对应的打开和关闭操作，进而实现照明灯和投影灯的打开和关闭。为了进一步降低驾驶人员的低头操作的概率，例如，控制模块还可以具备语音录入功能。即驾驶员通过发出语音指令，例如这些语音指令可以为“开启导航信息”或“关闭导航信息”或类似表达方式等。控制模块的语音录入模块接收该语音信息，并进行解析，以执行相应的操作。解析的实现方式例如可以为预先在控制模块的语音系统中存储语音指令，并使这些语音指令对应相应的操作。例如，使存储“导航系统”以及“开启导航系统”等语音指令，对应将导航信息投影到投影介质上的操作。当语音系统接收到驾驶人员的类似语音指令时，便可执行相应的操作。使用者可以 根据自己的习惯设置各种语音指令，本公开不做赘述。
另外，该控制模块例如被配置为可以提供待投影信息，例如导航信息、视频信息和图片信息等。控制模块为上述投影灯提供信息的方式例如包括两种：一种为在控制模块内设置导航系统，并将导航系统的导航信息提供给投影灯；或者提供信息接入的接口，从而将外部传输过来的待投影信息提供给投影灯。
需要说明的是，控制模块并不一定是与上述投影灯物理上彼此独立的部件，也可以与投影灯完全集成在一起，或者功能部分的集合在一起。例如，当投影灯与控制模块完全集成在一起时，可以留出以上所述有关控制模块的操作窗口。例如，当投影灯与控制模块集成后，可通过外壳固定于车上，外壳上可以预留开口，从该开口可以露出例如上述信息接口，以使外部信息源与该接口连接，或者该开口例如露出上述显示屏，以方便使用者通过显示屏进行相关操作。本领域技术人员不可对此进行限制解释。
图2为本发明实施例的车灯系统应用于汽车并显示一种导航信息的示意图。参照图2，例如，汽车的车灯系统将导航信息投影到地面上。例如，如图所示，投影到地面的投影信息为直线箭头及S65。例如，直线箭头表示汽车直行，S65表示当前时速，例如为65m/s。
图3为本发明实施例的车灯系统应用于汽车并显示另一种导航信息的示意图。参照图3，例如，汽车的车灯系统将导航信息投影到地面上。例如，如图所示，投影到地面的投影信息为左拐箭头及S25。例如，左拐箭头表示汽车向左转弯，S25表示当前时速，例如为25m/s。
图2和图3简单的演示了车灯系统的投影效果，需要指出的是，车灯系统可投影的信息不限于此。
在一个实施例中，该车灯系统还包括灯罩，所述照明灯和所述投影灯设置于所述灯罩之内。通过将照明灯和投影灯设置在灯罩内，可以为照明灯和投影灯提供有效保护，避免照明灯和投影灯发生损害。
在一个实施例中，所述投影灯可旋转的设置在灯罩内。例如，投影灯通过可旋转的底座设置。例如，底座的一端可以为固定部，另一端可以为与固定部连接且在连接后可以相对固定部旋转的旋转部。投影灯与旋转部固定连接，从而投影灯可以随着上述旋转部旋转。通过使投影灯可旋转设置，可以 自由调整投影灯的投影角度，从而保证驾驶员能够在安全驾驶的前提下，驾驶员能够清楚地观察到投影信息，例如导航信息。
在一个实施例中，所述照明灯包括出光部，在所述出光部的出光侧设置有光线调节装置，所述光线调节装置被配置为调整所述出光部所发出光线的方向。例如，如上所述，光线调节装置也可以设置在灯罩之内。通过设置光线调节装置，可以通过一个照明灯，同时实现远近灯照明，简化了结构，降低了成本。
需要说明的是，该光线调节装置例如可以是通过改变照明灯出光部发出光线的方向，调节照明灯所发出光的远近及强弱，以实现远近灯功能。
在一个实施例中，所述光线调节装置被配置为可以在第一状态和第二状态之间切换；在所述第一状态时，所述光线调节装置将所述出光部发出的光线发散；在所述第二状态时，所述出光部发出的光线透过所述光线调节装置时方向不变。例如，光线调节装置的第一状态与第二状态的切换可以通过手动切换来实现。手动切换是相对于自动切换而言的，即需要使用者根据外界环境决定使光线调节装置处于第一状态或第二状态，例如对于下文的聚合物分散液晶器件或多稳态液晶器件而言，可通过改变对其施加的电场来实现其在两种状态之间的转变。例如对于可形变的透镜，使用者可以根据外界环境以决定是否施加作用力而使透镜完成在平面状态与凹面状态或凸面状态之间的转换等，从而使光线调节装置对光线的调节作用发生变化。
在一个实施例中，所述光线调节装置连接到所述控制模块，所述控制模块控制所述光线调节装置在所述第一状态和所述第二状态之间切换。通过控制模块控制光线调节装置在第一状态和第二状态之间的切换，可以方便的实现远近光的转换。图4为本发明实施例的控制模块控制光线调节装置切换的逻辑框图。参照图4，例如，控制模块3包括输入单元31、处理单元32和执行单元33。输入单元31用于输入操作指令，并将该指令传输给处理单元；处理单元32用于对输入的指令进行解析，并生成可执行的操作指令；执行单元33根据操作指令进行操作，实现光线调节装置4从两个状态之间的切换。
输入单元31例如可以为语音识别装置，使用者发出的语音指令可以通过语音识别装置传递给处理单元32。如上所述，有关使用哪种语音指令，使用者可以根据习惯自行设置。例如，“1”对应光线调节装置的第一状态；“2”对 应光线调节装置的第二状态。或者采用其它的语音指令对应光线调节装置4的两个状态。另外，输入单元31也可以是汉字输入方式来输入操作指令。例如，输入单元31包括手写屏幕，当使用者希望光线调节装置4转换到第一状态时，可以输入数字“1”；当使用者希望光线调节装置4转换到第二状态时，可以输入数字“2”。也可以是其它的输入方式。
处理单元32在接受到输入单元31输入的操作指令后，对该操作指令进行解析。例如，当接收到语音“1”或数字“1”的信息时，可以首先采集有关光线调节装置4的状态的数据，并进行判断。如果光线调节装置4的当前状态为第一状态时，则不执行任何操作，即执行框图中的停止操作；如果光线调节装置4的当前状态为第二状态，即与通过输入单元31输入的状态不符时，则向执行单元33发送将光线调节装置4切换到第一状态的指令。执行单元33根据指令实现光线调节装置4从第二状态到第一状态的切换。
执行单元例如可以是与光线调节装置连接的动力结构，例如动力结构可以是发动机带动的齿轮传动结构，齿轮例如可以通过蜗杆、弹簧或皮带等将作用力施加到光线调节装置，从而通过改变光学调节装置的结构来实现光线调节装置状态的切换。例如，对于可形变的透镜，可以通过设置于透镜两侧的蜗杆对施加压力或拉力(例如蜗杆头部可以设置可伸吸盘)而使透明在凸透镜、凹透镜和平面镜之间转换。例如，两个蜗杆的运动可以通过如上所述的传动机构实现，例如使两个蜗杆可以沿各自轴线方向平动，以实现对透镜的挤压、拉伸等操作。
需要说明的是，本发明的实施例的光线调节装置例如是用于调节通过的光线的传播方向。光线条件装置例如可以为下文的聚合物分散液晶器件或多稳态液晶器件或者是透镜。对于这类光学器件，例如可以通过改变其结构，改变其对光线传播方向的影响。
在一个实施例中，例如，所述光线调节装置为聚合物分散液晶器件或多稳态液晶器件。图5a为为本发明实施例的光线调节装置处于第二状态且不影响照明灯光线方向的示意图；图5b本发明实施例的光线调节装置处于第一状态而使照明灯光线发散的示意图。参照图5a和5b，照明灯1的出光侧设置有光线调节装置4。例如，该光线调节装置为聚合物分散液晶器件或多稳态液晶器件。聚合物分散液晶器件或多稳态液晶器件具有透明态和散射态两种 状态。参照图5a，聚合物分散液晶器件或多稳态液晶器件处于透明状态，照明灯所发出的光线可保持原来的方向，实现远光照明。参照图5b，聚合物分散液晶器件或多稳态液晶器件处于散射态时，照明灯1所发出的光线被散射，实现近光照明。
在一个实施例中，所述光线调节装置为可调节透镜；所述可调节透镜具有平面、凹面和凸面三种状态，以透射、发散和聚焦所述出光部发出的光线。例如，可调节透镜由两个彼此相对且可产生形变的柔性透光片组成。当两个柔性透光片均为平面结构时，组成的可调节透镜为平面状态，此时，照明灯所发出的光线通过可调节透镜后可以按照原有方向传播；当两个柔性透光片形成凹凸结构，且通过凹面彼此相对组成可调节透镜时，则该可调节透镜为凸透镜，此时，照明灯所发出的光线通过该可调节透镜后发生聚焦，可以提高照明亮度；当两个柔性透光片形成凸凸结构，且通过凸面彼此相对组成可调节透镜时，则该可调节透镜为凹透镜，在此情况下，照明灯所发出的光线透过可调节透镜后发散，光线的照射距离较近，照明面积较大。如上所述，透镜的状态切换可以手动或通过上述控制模块实现，本发明对此不作赘述。
在一个实施例中，所述投影介质为地面。例如，在地面上的投影位置到投影灯的距离可以为1-5m，例如为2-4m。以使驾驶人员能够清楚地观察到地面上的投影信息。
在一个实施例中，所述控制模块集成导航系统，且导航信息可以通过所述投影灯投影到投影介质上。通过在控制模块中集成导航系统，使车灯系统的功能更加丰富，同时，不必与外设导航系统连接，简化了结构，提高了可用性。
在一个实施例中，所述控制模块集成视频、音频及图像的播放功能，且所述视频和所述图像通过所述投影灯投影到所述投影介质上。通过在控制模块中集成多种功能，可以使车灯系统的功能更加丰富，同时，不必与外设导航系统连接，简化了结构，提高了可用性。
在一个实施例中，所述控制模块包括接线口，所述接线口用于连接待投影的信息源。通过在控制模块设置接线口，可以方便的将各种待投影信息进行投影显示，扩展了车灯系统的应用范围。例如，手机的导航软件具有实时更新功能。例如，手机的导航软件可以实时显示公路的拥堵状况，从而驾驶 员可以根据拥堵状况，自行选择较佳的路线。但驾驶员低头看手机，同样存在很大的安全隐患。该车灯系统通过将手机的导航信息投影到例如地面上，可以在保证驾驶安全的情况下，为驾驶人员提供最佳的导航路线。
本发明的另一个方面提供了一种机动车，包括如上所述的车灯系统。该机动车由于采用了如前所述的车灯，因此也具有如上所述的技术效果，可以参照之前的描述。
另外，车灯系统应用于机动车时，例如车灯系统的照明灯和投影灯可以设置在机动车的前方。例如，对于汽车而言，照明灯和投影灯可以设置在汽车前端的两侧(即现有汽车的车灯通常的设置位置)，控制模块例如可以设置在汽车的驾驶室，以方便驾驶人员操作为宜，本发明对此不作限定。
在一个实施例中，机动车包括设置于机动车车头位置的凹槽、与该凹槽匹配的承接屏幕以及弹出复位机构；其中，弹出复位机构用于使承接屏幕弹出及复位；且在弹出时，所述承接屏幕在机动车前方面对所述投影灯的出光部设置；复位时，承接屏幕退回到凹槽中。这里的前方是指在机动车车尾指向车头的方向上，远离机动车车头一侧的位置。例如凹槽可以在垂直于机动车底盘方向上设置于机动车车灯(例如投影灯)与底盘之间，例如凹槽从机动车前端沿与机动车底盘基本平行的方向向机动车车尾延伸。例如，该位置距离机动车车头为0-5m，例如为0-3m。承接屏幕弹出时，可以采用投影灯将视频、图像和新闻等信息投影到承接屏幕上。机动车采用上述结构，可以在不影响机动车使用的前提下，方便驾驶人员欣赏视频、图片及新闻等信息。
在一个实施例中，例如，在所述承接屏幕弹出时，与所述投影灯彼此正对；所述投影灯将待投影信息投影到所述承接屏幕。通过承接屏幕与投影灯的正对设置，提高投影显示效果。
在一个实施例中，例如，在所述承接屏幕在弹出状态时，所述投影灯与所述承接屏幕的距离为2-5m。通过设置投影灯与承接屏幕的距离，可以提高待投影信息的显示效果。
在一个实施例中，例如凹槽为从汽车车头沿从车头指向车尾的方向延伸的结构，例如，凹槽可以基本上与汽车底盘平行。
图6为采用本发明实施例的车灯系统的汽车设置承接屏幕的结构示意图。参照图6，汽车的承接屏幕弹5出后，在机动车前方面对所述投影灯2的出 光部设置。驾驶员可以将待投影信息，例如视频等投影到承接屏幕5。
图6所示的承接屏幕的弹出例如可以通过以下方式实现：参照图7a和图7b，例如，屏幕分为可以彼此折叠的收拢部51和承接部52(对应于上述承接屏幕)两个部分，且收拢部51与承接部52通过连接机构53连接(图7a为承接部弹出到位后的示意图；图7b为承接部处于弹出过程的一个状态时的示意图)。例如连接机构可以为弹簧、卷簧或合叶等。例如，当连接机构53为弹簧时，在折叠状态下或在弹出过程中，承接部受到弹簧的作用力(图7b中箭头所示即为承接部在弹出过程中一个状态的受力情况)，具有恢复到与收拢部基本垂直的倾向。例如，折叠在一起的承接部和收拢部设置于汽车的上述凹槽内，此时，承接部由于受到汽车凹槽的远离地面的一侧内壁的限制而处于折叠状态。当折叠在一起的承接部和收拢部向外运动出凹槽以后，承载部受到弹簧恢复力的作用而弹出，从而处于如图6所示的状态。
在上述实施例中，例如，承接屏幕(对应于上述承接部)在凹槽内的运动可以通过滑轨和滚轮的配合实现。例如，该弹出复位机构例如包括设置于凹槽内的滑轨，收拢部的远离承接部的一个表面上例如设置与该滑轨匹配的滚轮。从而，在受到外力作用时，收拢部可以带动承接屏幕沿滑轨运动。
在一个实施例中，例如，承接屏幕的弹出还可以通过部分滑轨的转动来实现。例如，例如，上述滑轨可以分为固定段和可旋转段，固定段固定于上述凹槽内，可旋转段与固定段可旋转连接。承接屏幕的运动过程如下，牵拉承接屏幕，承接屏幕沿滑轨的固定段运动，当滚轮越过固定段以后，使滑轨的可旋转段旋转，从而使屏幕从基本上与底盘平行状态调整为面对投影灯的出光部的状态。
承接屏幕退回到凹槽中的操作例如可以采用手动或机械方式完成。退回过程与上述过程相反，在此不作详细说明。
以上各实施例可以彼此组合，且具有更好的技术效果。
此说明书中所描述的许多功能部件都被称为模块或单元，以便更加特别地强调其实现方式的独立性。
本发明实施例中，模块或单元可以用软件实现，以便由各种类型的处理器执行。举例来说，一个标识的可执行代码模块可以包括计算机指令的一个或多个物理或者逻辑块，举例来说，其可以被构建为对象、过程或函数。尽 管如此，所标识模块的可执行代码无需物理地位于一起，而是可以包括存储在不同物理上的不同的指令，当这些指令逻辑上结合在一起时，其构成模块并且实现该模块的规定目的。
实际上，可执行代码模块可以是单条指令或者是许多条指令，并且甚至可以分布在多个不同的代码段上，分布在不同程序当中，以及跨越多个存储器设备分布。同样地，操作数据可以在模块或单元内被识别，并且可以依照任何适当的形式实现并且被组织在任何适当类型的数据结构内。所述操作数据可以作为单个数据集被收集，或者可以分布在不同位置上(包括在不同存储设备上)，并且至少部分地可以仅作为电子信号存在于系统或网络上。
在模块或单元可以利用软件实现时，考虑到现有硬件工艺的水平，所以可以以软件实现的模块，在不考虑成本的情况下，本领域技术人员都可以搭建对应的硬件电路来实现对应的功能，所述硬件电路包括常规的超大规模集成(VLSI)电路或者门阵列以及诸如逻辑芯片、晶体管之类的现有半导体或者是其它分立的元件。模块或单元还可以用可编程硬件设备，诸如现场可编程门阵列、可编程阵列逻辑、可编程逻辑设备等实现。
在本文中，诸如“第一”、“第二”等术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不要求或者暗示这些实体或操作之间存在任何关系或者顺序。术语“包括”、“包含”这些表述为开放式的，并不排除所包括的过程、方法、物品，还存在其他要素。还需要说明的是，“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
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2016年4月28日递交的中国专利申请第201610279970.9 号的优先权，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。
