具体实施方式
以下,适当参照附图,详细地说明本公开的实施方式。不过,有时省略过于详细的说明。另外,附图和以下的说明是为了使本领域技术人员充分地理解本公开而提供的,并非意图由此限定实用新型授权权利要求书所记载的主题。
(第1实施方式)
图1是表示第1实施方式的电子镜1的一例的主视图。图2是表示第1实施方式的电子镜1的一例的分解立体图。图3是图1所示的电子镜1的A-A向视的剖视图。另外,将电子镜1的宽度方向设为X轴方向,将电子镜1的高度方向设为Y轴方向,将电子镜1的深度方向设为Z轴方向。此外,将在电子镜1中显示图像的一侧设为正面侧,将与正面侧相反的那一侧设为背面侧。
电子镜1例如是配置于车辆的室内的电子内镜。电子镜1作为显示装置和镜发挥功能。具体而言,电子镜1在作为显示装置发挥功能的情况下显示拍摄车辆的后方的摄像机拍摄到的图像。此外,电子镜1在作为镜发挥功能的情况下通过反射光来映射车辆的后方。此外,电子镜1是显示装置和车载显示装置的一例。
电子镜1具有作为显示装置发挥功能的显示器模式和作为镜发挥功能的镜模式。显示器模式是电子镜1显示拍摄车辆的后方的摄像机拍摄到的图像的模式。镜模式是电子镜1通过使入射到电子镜1的光反射来映射车辆的后方的模式。例如,电子镜1通过接受利用杆等进行的操作来切换显示器模式和镜模式。
如图2所示,电子镜1具有罩透镜10、双面胶带20、框架30、显示器40以及外壳50。罩透镜10是使可见光透过的罩。更详细而言,罩透镜10以覆盖电子镜1的正面的方式由透明的构件形成。例如,罩透镜10由树脂形成。罩透镜10也可以由玻璃形成。罩透镜10由树脂形成,从而与由玻璃形成的情况相比轻量化。
此外,罩透镜10在与框架30对应的位置具有通过反射可见光来映射图像的镜部11。与框架30对应的位置是指在从正面观察电子镜1时至少局部与框架30重叠的位置。镜部11也可以以在从正面观察电子镜1时与框架30的整体重叠或自框架30伸出的方式形成。镜部11是利用形成为镜面状的银色的覆膜使入射的光反射的部分。由此,镜部11像镜子那样映射图像。在此,罩透镜10是透明的,因此有时能够经由罩透镜10视觉辨认处于比罩透镜10靠背面侧的位置的构件。处于背面侧的构件例如是后述的双面胶带20和框架30。在罩透镜10设置镜部11,从而镜部11能够遮挡双面胶带20、框架30,而且映射车辆的后方。由此,电子镜1在镜模式的情况下能够使整面成为镜子。
双面胶带20是在两面涂布有粘接剂的带。双面胶带20将罩透镜10和框架30粘接。
框架30是与外壳50接合且覆盖显示器40的边缘的外框。此外,框架30支承罩透镜10。例如,框架30通过利用双面胶带20粘贴来支承罩透镜10。
此外,框架30包括覆盖显示器40的边缘的外框部31和与外壳50接合的接合部32。外框部31具有与显示器40所具有的LCD(Liquid Crystal Display)单元44大致平行且覆盖显示器40的边缘的平面状的板。接合部32具有供外壳50所具有的凸部54插入的凹部33。接合部32通过向凹部33插入凸部54而与外壳50接合。
显示器40显示图像。更详细而言,显示器40显示拍摄车辆的后方的摄像机拍摄到的图像。另外,显示器40只要通过有线或无线的方式连接,就不限于显示拍摄车辆的后方的摄像机拍摄到的图像,也可以显示其他摄像机拍摄到的图像。
此外,在显示器40和框架30之间配置有垫片41。垫片41填充显示器40和框架30之间的间隙。由此,垫片41抑制尘埃、尘土等垃圾进入到电子镜1的内部的情况。
显示器40包括显示器壳体42、偏振光反射层43、LCD单元44以及显示器控制部46。显示器壳体42是覆盖显示器40的壳体。
偏振光反射层43设于罩透镜10和显示器40之间且是显示器40的表面441。此外,偏振光反射层43使经由罩透镜10入射的光的一部分反射且使显示器40显示的图像的光透过。偏振光反射层43是偏振光反射部的一例。即,偏振光反射层43在镜模式的情况下作为镜子反射光,在显示器模式的情况下使显示器40显示的图像的光朝向正面侧透过。
更详细而言,偏振光反射层43使向特定方向偏振或极化的光透过,使与特定方向不同的方向的光反射。此外,偏振光反射层43使LCD单元44出射的光透过。此外,偏振光反射层43利用OCA(Optical Clear Adhesive)等透明的粘接剂45粘贴于显示器40的表面441。具体而言,偏振光反射层43粘贴于LCD单元44的表面441。
LCD单元44是在玻璃基板之间注入有液晶的构件。显示器40通过经由LCD单元44出射光来显示图像。
显示器控制部46控制显示器40。例如,显示器控制部46具有控制显示器40的电路基板、向LCD单元44放射光的背光源、从搭载于车辆的摄像机接收图像的接收部等。显示器控制部46在显示器模式的情况下使搭载于车辆的摄像机拍摄到的图像显示于LCD单元44。
外壳50收纳显示器40且安装于车辆。外壳50包括收纳部51、臂部52以及安装部53。收纳部51是收纳显示器40的壳体。此外,收纳部51在正面侧具有凸部54。凸部54向在框架30的接合部32设置的凹部33插入。由此,外壳50的收纳部51与框架30接合。而且,外壳50和框架30是覆盖显示器40的周围的壳体。即,外壳50和框架30是壳体的一例。
臂部52是将外壳50和安装部53连结的臂状的构件。此外,臂部52也可以具有变更显示器40的角度的关节。由此,使用者能够将电子镜1调整为易于观察的角度。例如,电子镜1也可以在显示器模式和镜模式中能够变更角度。
安装部53是安装于车辆的室内的构件。例如,安装部53安装于车辆的顶棚、前挡风玻璃。由此,电子镜1安装于车辆。
像以上那样,第1实施方式的电子镜1包括使可见光透过的罩透镜10、显示图像的显示器40以及配置于显示器40的LCD单元44的偏振光反射层43。而且,偏振光反射层43使经由罩透镜10入射的光反射且使显示于LCD单元44的图像的光偏振。即,偏振光反射层43还作为使显示于LCD单元44的图像的光偏振的偏振片发挥功能。由此,电子镜1能够消除多个构件的作用的重复。
此外,电子镜1在LCD单元44配置有偏振光反射层43。由此,能够由比玻璃轻量的树脂形成罩透镜10。在此,树脂比玻璃柔软,易于变形。因此,若在由树脂形成的罩透镜配置偏振光反射层,则难以维持偏振光反射层的平面度,存在反射图像失真这样的问题。在第1实施方式的电子镜1中,在硬度较高的LCD单元44配置有偏振光反射层43。由此,能够维持电子镜1的偏振光反射层43的平面度,能够抑制反射图像失真的情况。
此外,如图3所示,罩透镜10粘贴于框架30的正面侧。框架30也可以具有覆盖罩透镜10的端的边缘。在一些国家、地区,根据法规要求具有覆盖罩透镜10的端的边缘,因此能够在这样的国家、地区利用电子镜1。
(第2实施方式)
图4是表示第2实施方式的电子镜1a的一例的分解立体图。图5是第2实施方式的电子镜1a的剖视图。另外,由于第2实施方式的电子镜1a的正面与图1所示的第1实施方式的电子镜1大致相同,因此省略主视图。
如图4所示,电子镜1a具有罩透镜10a、OCA 60、VRM(Variable ReflectanceMirror)70、双面胶带20、框架30a、显示器40以及外壳50。
电子镜1a具有在镜模式的情况下作为镜发挥功能的VRM 70。在罩透镜10a的从罩透镜10a的边缘到设有VRM 70的位置的区域设有像镜子那样映射图像的镜部11。在图5所示的例子中,在从正面观察电子镜1a时,在比设有VRM 70的位置靠外侧的位置设有镜部11。
OCA 60是将罩透镜10a和VRM 70粘接的透明的粘接剂。
VRM 70根据被施加的电压来变更针对入射光的反射率和透过率。例如,VRM 70在显示器模式的情况下提高针对入射光的透过率。即,VRM 70使配置于比VRM 70靠背面侧的位置的显示器40显示的图像的光透过。另一方面,VRM 70在镜模式的情况下提高针对入射光的反射率。即,VRM 70使经由罩透镜10a入射的光反射。
VRM 70具有偏振部71、TN(Twisted Nematic)液晶部72以及粘接剂73。此外,在LCD单元44的表面441设置的偏振光反射层43作为VRM 70的局部发挥功能。
偏振部71设于罩透镜10a和偏振光反射层43之间且是靠罩透镜10a侧的位置,使经由罩透镜10a入射的光偏振。更详细而言,偏振部71是使经由罩透镜10a入射的光中的向特定方向偏振或极化的光透过的偏振片。此外,偏振部71吸收与特定方向不同的方向的光。
TN液晶部72是TN方式的液晶板。TN液晶部72位于偏振部71和偏振光反射层43之间,变更经由偏振部71入射的光的偏振方向。TN液晶部72是液晶部的一例。更详细而言,TN液晶部72在被施加电压的情况下将液晶材料的分子的排列方式变为垂直方向。由此,TN液晶部72使透过的光直向前进。另一方面,TN液晶部72在未被施加电压的情况下不变更液晶材料的分子的排列方式。由此,TN液晶部72变更透过TN液晶部72的光的偏振方向。例如,TN液晶部72将光的偏振方向偏转90度。液晶部的例子不限于此。例如,也可以是在被施加电压的情况下变更透过的光的偏振方向且在未被施加电压的情况下使透过的光直向前进这样的液晶部。
此外,TN液晶部72利用粘接剂73粘贴于偏振部71。粘接剂73与粘接剂45同样,能够使用透明的OCA等。
偏振光反射层43使与偏振部71相同方向的光透过。换言之,偏振光反射层43使在TN液晶部72中直向前进的光透过。此外,偏振光反射层43使被TN液晶部72改变了偏振方向的光反射。由此,偏振光反射层43使经由TN液晶部72入射的光的一部反射且使显示器40显示的图像的光透过。
在这样的结构中,在显示器模式的情况下,偏振光反射层43使LCD单元44显示的图像的光中的向特定方向偏振或极化的光透过。此外,在显示器模式的情况下,对VRM 70施加电压。由此,TN液晶部72不变更从偏振光反射层43入射的光的偏振方向而使其直向前进。此外,透过TN液晶部72的光透过偏振部71。然后,透过偏振部71的光经由OCA 60和罩透镜10a放出。由此,电子镜1a显示图像。
另一方面,在镜模式的情况下,不对TN液晶部72施加电压。由此,TN液晶部72利用液晶材料的分子变更从偏振部71入射的光的偏振方向。然后,偏振光反射层43使被TN液晶部72改变了偏振方向的光反射。
TN液晶部72变更偏振光反射层43反射的光的偏振方向。其结果,透过TN液晶部72的光恢复为透过偏振部71时的角度。然后,透过TN液晶部72的光透过偏振部71。透过偏振部71的光经由OCA 60和罩透镜10a放出。这样,电子镜1a在镜模式中反射光。
如图5所示,TN液晶部72和偏振部71配置于罩透镜10a和框架30a之间。框架30a为了设置供TN液晶部72和偏振部71配置的空间而具有台阶形状。框架30a在比利用双面胶带20与罩透镜10a粘接的面低一层的位置具有供TN液晶部72和偏振部71配置的配置部34。而且,显示器40配置于比配置部34靠背面侧的位置。
像以上那样,第2实施方式的电子镜1a包括设于罩透镜10a和偏振光反射层43之间且使经由罩透镜10a入射的光偏振的偏振部71和变更经由偏振部71入射的光的偏振方向的TN液晶部72。而且,在显示器40的LCD单元44配置的偏振光反射层43还作为VRM 70的偏振光反射板发挥功能。由此,电子镜1a能够在多个构件中消除作用的重复。
此外,如图5所示,罩透镜10a粘贴于框架30a的正面侧。框架30a也可以具有覆盖罩透镜10a的端的边缘。在一些国家、地区,根据法规要求具有覆盖罩透镜10a的端的边缘,因此能够在这样的国家、地区利用电子镜1a。
(第3实施方式)
图6是表示第3实施方式的电子镜1b的一例的分解立体图。图7是第3实施方式的电子镜1b的剖视图。另外,由于第3实施方式的电子镜1b的正面与图1所示的第1实施方式的电子镜1大致相同,因此省略主视图。
如图6所示,电子镜1b具有罩透镜10、OCA 60、显示器40、双面胶带20、框架30b以及外壳50。
OCA 60是透明的粘接剂。罩透镜10和显示器40由OCA 60粘接。更详细而言,OCA 60将罩透镜10和在LCD单元44的表面441形成的偏振光反射层43粘接。换言之,罩透镜10和显示器40由OCA 60粘接。因此,如图7所示,框架30b没有覆盖显示器40的边缘的外框。
显示器40利用OCA 60粘接于罩透镜10。此外,显示器40具有LCD单元44,该LCD单元44显示搭载于车辆的摄像机拍摄到的图像。而且,LCD单元44在正面侧的表面441具有偏振光反射层43。
像以上那样,在第3实施方式的电子镜1b中,罩透镜10和配置有偏振光反射层43的LCD单元44由OCA 60粘接。在该情况下也是,偏振光反射层43使经由罩透镜10入射的光反射,使显示于LCD单元44的图像的光偏振。即,偏振光反射层43还作为使显示于LCD单元44的图像的光偏振的偏振片发挥功能。由此,电子镜1b能够在多个构件中消除作用的重复。
此外,如图7所示,罩透镜10粘贴于框架30b的正面侧。框架30b也可以具有覆盖罩透镜10的端的边缘。在一些国家、地区,根据法规要求具有覆盖罩透镜10的端的边缘,因此能够在这样的国家、地区利用电子镜1b。
(第4实施方式)
图8是表示第4实施方式的电子镜1c的一例的主视图。图9是表示第4实施方式的电子镜1c的一例的分解立体图。图10是图8所示的电子镜1c的A-A向视的剖视图。
第4实施方式的电子镜1c不具有电子镜1的罩透镜10和双面胶带20。即,如图9所示,电子镜1c具有框架30c、显示器40以及外壳50。
如图10所示,电子镜1c没有罩透镜10,因此显示器40暴露。更详细而言,在电子镜1c中,在LCD单元44的表面441设置的偏振光反射层43暴露。即,偏振光反射层43设于显示器40的表面441,使从显示器40的相反侧入射的光的一部分反射且使显示器40显示的图像的光透过。
此外,由于没有罩透镜10,因此框架30c成为显示器40的外框。由此,框架30c成为具有曲线的外观。
像以上那样,第4实施方式的电子镜1c不具有罩透镜10。在该情况下也是,偏振光反射层43使入射的光反射,使显示于LCD单元44的图像的光偏振。即,偏振光反射层43还作为使显示于LCD单元44的图像的光偏振的偏振片发挥功能。由此,电子镜1c能够在多个构件中消除作用的重复。
说明了本公开的几个实施方式,但这些实施方式是作为例子而提出的,并非意图限定实用新型的范围。这些实施方式能够以其他各种形态实施,在不脱离实用新型的主旨的范围内,能够进行各种省略、替换、变更。这些实施方式、其变形包含于实用新型的范围、主旨,同样包含于实用新型授权权利要求书所记载的实用新型和其等同的范围。
