发明内容
本申请实施方式提供了一种减小厚度方向占用空间的光学显示器、座椅及交通工具。
第一方面,本申请提供了一种光学显示器,包括:
显示主体,包括外壳及光源单元,所述外壳设有内腔,所述光源单元收容于所述内腔内;及
电学部件,位于所述外壳的外部,所述电学部件与所述光源单元电连接。
本申请中,将电学部件设于外壳的外部,即电学部件与位于内腔的光源单元未设置在同一腔体内,电学部件未占用外壳的内部空间,有利于减小显示主体的占用空间,这样一来,方便根据需要将电学部件与显示主体安装在不同的空间内,提高了光学显示器的安装灵活性,例如,光学显示器在安装至座椅时,显示主体可以安装至头枕部分,电学部件可以安装至头枕下方。
另外,将电学部件设于外壳的外部,无需在外壳上设置供电学部件进行散热的散热结构,降低了外壳内部光路中的杂光的反射次数,有利于提高显示主体输出的成像光的输出质量,提高了光学显示器的显示质量。
还有,常规的光学显示器中,为保证显示效果,由于光学部件与电学部件同腔设置,而光学部件与电学部件对于结构的设计要求(例如密封等级)不相同,这可能导致光学显示器的结构较为复杂。而本申请中,通过将电学部件设置在外壳外,使电学部件与内腔的光学元件在结构上相互独立,有利于简化光学显示器的结构。
根据第一方面,本申请的一种可能的实现方式中,所述电学部件包括主控器和第一线缆,所述第一线缆电连接于所述光源单元与所述主控器之间。

驱动件带动显示主体旋转时,显示主体相对电学部件的各个器件的位置需不断改变以达到适配观看者的目的,即显示主体与电学部件之间发生相对移动,显示主体、电学部件之间的线缆需要冗余才能尽可能减少线缆活动,由于驱动件、操控板、主控器均固定在骨架上,仅有光源单元随显示主体旋转,驱动件、操控板、主控器三者之间相对静止。因此,光源单元和主控器之间的第一线缆需要冗余,减少主控器与驱动件之间第三线缆冗余量,减少操控板与主控器之间第四线缆冗余量。
第三方面,本申请提供一种交通工具,包括如上所述的光学显示器,所述外壳安装于所述交通工具上。
根据第三方面,本申请的一种可能的实现方式中,所述光学显示器位于所述交通工具的副驾驶位置。

具体实施方式
请参阅图1,本申请一实施方式提供一种交通工具1000,本申请实施方式中的交通工具1000可以是汽车、飞机、轮船、火箭等已知的交通工具,还可以是未来新出现的交通工具。汽车可以是电动汽车、燃油车或混合动力车,例如,纯电动汽车、增程式电动汽车、混合动力电动汽车、燃料电池汽车、新能源汽车等,本申请对此不做具体限定。
交通工具1000包括工具主体200及安装于工具主体200上的座椅。座椅包括第一座椅300及第二座椅500,用于供乘坐者乘坐。本实施方式中,第一座椅300为设于工具主体200内的前排座椅。第二座椅500为设于排列于第一座椅300后的后排座椅,用于供乘坐者乘坐。在本申请的其他实施方式中,第一座椅300可以不是前排座椅。
请结合参阅图2,第一座椅300包括座椅主体301及安装于座椅主体301上的光学显示器303。在本申请中,将乘坐在第二座椅500上观看光学显示器303的乘坐者称为观看者。可以理解,光学显示器303也可以安装在交通工具1000的副驾驶位置(如图1所示),即安装于交通工具的仪表板(Instrument Panel,IP)台上。
请参阅图3,座椅主体301还包括骨架3015及包覆物3016。骨架3015用于定型第一座椅300及承重。包覆物3016包裹于骨架3015上,进而使第一座椅300形成收容腔3017。包覆物3016通常包括柔性的填充物,以提高用户乘坐在第一座椅300上的舒适感。收容腔3017用于收容光学显示器303。
座椅主体301还包括头枕区3018及依靠区3019。头枕区3018对应座椅主体301支撑乘坐者的头部区域。依靠区3019对应座椅主体301的其他区域。光学显示器303位于第一座椅300的头枕区3018,以能够使第二座椅500上的观看者与光学显示器303保持平视,提高观看者的观看舒适感。
光学显示器303的至少部分收容于收容腔3017内,光学显示器303能够从包覆物3016露出,以向座椅主体301外输出承载图像信息的成像光。光学显示器303包括支撑架31、显示主体32封装壳34、俯仰机构35及电学部件37。
支撑架31固定于第一座椅300的骨架3015上并收容于收容腔3017内,用于支撑显示主体32。显示主体32收容于收容腔3017内并位于头枕区3018。请结合参阅图3与图4,显示主 体32与支撑架31转动连接,用于输出承载图像信息的成像光。封装壳34固定于支撑架31上,用于收容及保护俯仰机构35,起到防尘、降噪、抗振动、抗冲击等作用。俯仰机构35收容于封装壳34内。俯仰机构35连接于支撑架31与显示主体32之间,俯仰机构35用于带动显示主体32相对支撑架31转动,以适应不同身高人群,不同坐姿甚至站立观看的需求,提高了用户的使用便利性。电学部件37设于第一座椅300上并位于显示主体32的外部,用于向显示主体32提供电能及输入图像信号等等。
在光学显示器303安装于第一座椅300中时,由于车载座椅的骨架结构复杂,造成第一座椅300内部可预留给光学显示器的空间有限且相对分散。在第一座椅300的厚度方向(第一座椅300与第二座椅500的排列方向),预留给光学显示器303的安装空间非常有限。而出于光学成像的要求,光学显示器303需要一个较大的光腔。
相较于常规的电学部件与光学部件同腔设置的光学显示器,本申请中,将电学部件37设置于显示主体32的外部,而不占用显示主体32的内部空间,即电学部件37与显示主体32的内部光学元件分腔设置,有利于减小显示主体32的光腔的占用空间,有利于显示主体32的小型化。可根据收容腔3017的内部空间,对显示主体32、电学部件37等部件进行安装布局,提高了光学显示器303的安装灵活性,亦提高了第一座椅300内的收容腔3017的空间利用率。
还有,电学部件37在工作时会产生热量,由于电学部件37设置在显示主体32的外部,则无需在显示主体32上设置供电学部件37进行散热的散热结构。由于显示主体32未设置散热结构,降低了显示主体32内部光路中的杂光的反射次数,有利于提高显示主体32输出的成像光的输出质量,提高了光学显示器303的显示质量。
支撑架31包括支撑部311、第一支撑臂313及第二支撑臂315。支撑部311连接于第一支撑臂313与第二支撑臂315之间。封装壳34固定于第一支撑臂313上。封装壳34位于第一支撑臂313与显示主体32之间。俯仰机构35连接于第一支撑臂313与显示主体32之间。第一支撑臂313、第二支撑臂315可以通过焊接或紧固件连接等方式固定到骨架3015上,本申请对支撑架31与骨架3015之间的固定方式不作限定。在本申请的其他实施方式中,可以省略支撑架31,而直接将显示主体32与骨架3015等结构转动连接。
请参阅图5,显示主体32包括外壳1、光源单元3、透反光学元件5及曲面镜7。外壳1设有内腔101。光源单元3固定于外壳1上并收容于内腔101内,用于出射成像光。透反光学元件5固定于外壳1上,用于透射及反射成像光。透反光学元件5露出座椅主体301外,以能够与观看者平视。透反光学元件5即为显示主体32的出光面。曲面镜7固定于外壳1上,用于反射成像光。电学部件37、封装壳34及俯仰机构35位于内腔101的外部。外壳1、光源单元3、透反光学元件5及曲面镜7共同围成光学显示器303的光路腔体(简称光腔),以在显示主体32的内部形成成像光的光路。可以理解,本申请对显示主体32的结构不作限定,显示主体32可以包括其他光学元件,例如,反射镜等。
如图6所示,光源单元3发出的成像光经透反光学元件5反射到曲面镜7,曲面镜7反射的成像光经透反光学元件5后透射到外壳1的外部。其中,光源单元3可以称为图像源。透反光学元件5可以反射光源单元3发出的成像光至曲面镜7,透射曲面镜7反射的成像光经透反光学元件5透射到外壳1的外部,再进入到眼睛80中,眼睛80看到放大的虚像。虚像是可以由眼睛80观看而不需要被光幕接收。如图6所示,光源单元3发出具有一定发散角的成像光L,经过透反光学元件5及曲面镜7反射后再进入眼睛80,大脑会以“光线沿直线传播”的经验对光线反向追迹,认为成像光L以反向延长的交点为物点,即虚像点。
本申请中,由于光源单元3、透反光学元件5及曲面镜7均未通过其他转接件(例如各自的固定框体)而直接固定于同一个外壳1上,减少了光学显示器303的元件数量,降低了光学显示器303的装配难度,提高了光学显示器303的装配精度,简化了光学显示器303的结构,进而有利于提高光学显示器303的光路系统的精度,及提高光学显示器303的成像光的输出质量。
还有,光源单元3、透反光学元件5及曲面镜7之间的相对位置由光学原理确定,有利于提高光学显示器303的显示效果。光学部件的组成部分(光源单元3、透反光学元件5及曲面镜7)集成在外壳1内,而电学部件37位于外壳1的外部,有利于针对光学部件、电学部件37各自所需的防护级别外进行密封设计(包括防尘防水结构),有效阻止大颗粒物质进入外壳1的内腔101,从而保证光学显示器303的显示效果。
本申请的一些实施方式中,外壳1包括出光部11、背部13及连接侧部15。出光部11、背部13及连接侧部15共同围成内腔101。出光部11与背部13沿显示主体32的第一方向(如图3、图6中所示的X方向)相对设置。本实施方式中,出光部11包括与内腔101连通的透光区域。出光部11的法向沿第一方向。曲面镜7和光源单元3位于内腔101中。透反光学元件5固定盖设于出光部11上,在显示主体32的第一方向上,曲面镜7位于背部13与透反光学元件5之间。连接侧部15连接于出光部11与背部13之间。俯仰机构35与连接侧部15连接(如图3所示),用于带动显示主体32绕沿显示主体32的第二方向(如图3中所示的Y方向)设置的第一旋转轴线相对支撑架31转动。曲面镜7固定于连接侧部15或背部13,用于将透反光学元件5反射的成像光经出光部11反射到外壳1的外部,以供用户观看。
由于俯仰机构35与连接侧部15相连接,俯仰机构35避开背部13设置,进而减少占用或不占用显示主体32在第一方向(厚度方向)上的空间,减少了光学显示器303在第一方向上的占用空间,有利于将光学显示器303安装在狭小的收容腔3017内。
请参阅图6与图7,连接侧部15包括第一侧部151、第二侧部153、第三侧部155及第四侧部157。第一侧部151与第二侧部153沿第二方向(如图7中所示的Y方向)相对设置,第三侧部155与第四侧部157沿第三方向(如图7中所示的Z方向)相对设置。第三侧部155可以视为显示主体32的顶部,第四侧部157可以视为显示主体32的底部。光源单元3固定于第三侧部155(如图6所示)上。可以理解,本申请对外壳1及显示主体32的结构不作限定,外壳1承载光源单元3等光学元件,显示主体32包括出光部11、背部13及连接侧部15即可。
在显示主体32的第三方向上,沿第三侧部155朝向第四侧部157的方向上,光源单元3的位置高于曲面镜7及透反光学元件5,使用户在观看光学显示器303时,难以透过透反光学元件5看到位于第三侧部155上的光源单元3,相当于光源单元3隐藏在第三侧部155内,光源单元3的杂散光不会直接透射透反光学元件5到达人眼,从而有利于提高用户的使用体验,也提高光学显示器303的成像质量。
本申请的一些实施方式中,光源单元3采用液晶显示(liquid crystal display,LCD)成像技术。LCD成像利用了液晶的光电效应原理,液晶分子受外加电场的影响而改变排列状态,不同排列状态的液晶分子能够控制对光的透过率。例如,在两个偏振方向互相垂直的偏振片中间为液晶分子,在不加电场时,液晶分子能够使经过第一偏振片的线偏振光偏振方向旋转90°,此时,光线以最大透过率通过第二偏振片;在施加电场时,液晶分子排列状态改变,对偏振光的旋转角度也发生改变,光线透过第二偏振片的强度随之减弱。LCD显示屏每个像素点由三原色组成,通过控制三原色的强弱来实现彩色图像的显示。本申请对光源单元3的光源 种类不作限定,例如,光源单元3还可以采用数字光处理(digital light processing,DLP)技术、激光扫描投影等。
透反光学元件5能够透射部分入射至透反光学元件5上的入射光及反射部分入射光的光学元件。例如,透反光学元件可以透射50%的入射光,透反光学元件可以反射50%的入射光;或者,透反光学元件可以透射30%的入射光,透反光学元件可以反射70%的入射光。透反光学元件5透射入射光占整体入射光的比例,可以根据需要进行选用。透反光学元件5的材质可以选用玻璃等。
本实施方式中,曲面镜7是匹配光学成像需要的自由曲面的反射镜。
传统光学设计中所采用的光学元件的面型为标准球面,一般需要多片球面镜进行配合矫正像差,从而导致其光学结构比较复杂,占用空间较大。
随着光学产业的发展,面型较为复杂的非球面的设计与制造技术到得到了很大提高,非球面一般是指具有回转轴的抛物面、椭球面、渐开面、双曲面等二次曲面以及高次曲面,还有非回转非球面,如离轴非球面。根据使用场景的不同,一片非球面通常可以代替两片或多片球面矫正像差,从而简化光学结构,实现光路的微型化与轻量化。
相对于非球面,自由曲面是一种面型更为复杂的光学结构,其表面各点的曲率半径都不相同,面型的自由度非常高。自由曲面不仅能够代替多片非球面矫正像差,还能最大限度的提高光学质量,精简光学结构。光学自由曲面面形结构复杂,自由度高,没有明确的表达式定义,一般认为不具备全局的旋转对称性、无统一的光轴、整个表面存在多个曲率半径的光学表面为光学自由曲面。
本申请的其他实施方式中,曲面镜7还可以采用球面反射镜或非球面反射镜,本申请对此不作限定。
请再次参阅图3与图4,本申请的一些实施方式中,封装壳34包括连接设置的第一封装部341及第二封装部343。俯仰机构35包括传动组件353及驱动件356。传动组件353连接于显示主体32与第一支撑臂313之间。
传动组件353包括第一传动结构及第二传动结构。第一传动结构位于显示主体32的第一侧部151所在侧。第一传动结构能够绕第二旋转轴线转动。第二传动结构与显示主体32连接,通过第一传动结构绕第二旋转轴线的旋转运动,转化为第二传动结构及显示主体32绕第一旋转轴线的旋转运动,减小了俯仰机构35的占用空间。
本实施方式中,第一传动结构包括蜗杆3531,第二传动结构包括蜗轮3533。蜗杆3531包括固定连接的蜗杆头3535及杆体3537。蜗杆头3535与蜗轮3533均收容于第一封装部341内。杆体3537收容于第二封装部343内。蜗杆头3535与蜗轮3533啮合。杆体3537的一端与蜗杆头3535固定连接。蜗轮3533止转地套设于转轴3515外。本实施方式中,蜗杆3531为单头蜗杆,单头蜗杆具有较强的自锁功能,通常情况下,外力不易改变光学显示主体32的位置。
蜗轮3533与蜗杆3531之间的配合具备自锁功能,可以实现显示主体32在俯仰转动范围内的任意角度可悬停,提高了显示主体32的位置稳定性,即使在显示主体32不断被震动的情况下(例如交通工具1000行驶在颠簸路况下)仍能够保持显示主体32相对支撑架31的位置稳定,而不晃动产生异响,提高了光学显示器303的使用可靠性。
驱动件356与杆体3537远离蜗杆头3535的一端连接并位于封装壳34外,用于向显示主体32提供驱动力。驱动件356通过蜗杆3531驱动蜗轮3533转动,进而带动显示主体32相对于支撑架31转动。可以理解,在其他实施方式中,驱动件356也可以收容到封装壳34内,以受到封装壳 34的保护。
本实施方式中,杆体3537活动地穿设于骨架3015,驱动件356固定于骨架3015上并位于依靠区3019。请参阅图8,驱动件356设置在了依靠区3019,使得驱动件356远离了头枕区3018,远离乘坐在第一座椅300上的乘坐者的耳朵。另外,驱动件356收容于收容腔3017内,第一座椅300上的包覆物3016亦能够很好地隔绝驱动件356所产生的噪音,进一步降低驱动件356对乘坐在第一座椅300上的乘坐者影响。由于依靠区3019有充裕的安装空间,对于驱动件356尺寸和形状的限制较少,方便驱动件356的安装。
由于车载环境下,设于第一座椅300的椅背上的光学显示器303为了适配人眼,需要俯仰调节的角度范围不大,车载光学显示器需要的转速很低。本实施方式中,显示主体32的重心位于第一旋转轴线上,以提高显示主体32在绕第一旋转轴线旋转时的平衡稳定性。可以理解,重心所在位置也可以与第一旋转轴线间隔设置。由于蜗轮蜗杆可以进行减速,对驱动件356的负载要求不高,驱动件356可以采用步进电机,步进电机可以慢速驱动蜗杆。另外,步进电机的初始振动和噪音都能控制到很小,步进电机及传动系统寿命较优。
本申请其他实施方式中,驱动件356也可以采用直流减速电机、交流电机、伺服电机等其他类型电机,根据功能需要可以给驱动件356增配减速箱、防堵转装置、角度检测传感器、编码器等等。
请结合参阅图9与图10,电学部件37包括主控器371、第一线缆372、第二线缆373、第三线缆374、操控板375及第四线缆376。
主控器371固定于骨架3015(如图11a所示)上并位于依靠区3019,用于控制光源单元3与驱动件356。由于主控器371位于依靠区3019不占用头枕区3018,提高光学显示器303的安装灵活性及收容腔3017的空间利用率。
第一线缆372电连接于光源单元3与主控器371之间。第一线缆372用于将主控器371输出的图像信号(例如视频信号)传输给光源单元3。第二线缆373电连接于光源单元3与主控器371之间。第二线缆373用于向光源单元3供电,保证光源单元3的稳定输出。第一线缆372和第二线缆373可以合并成一根。
第三线缆374电连接于主控器371与驱动件356之间,用于将主控器371输出的驱动信号传输给驱动件356,实现主控器371控制驱动件356。
操控板375固定于骨架3015(如图10所示)上并位于显示主体32的第四侧部157所在一侧。操控板375设置在依靠区3019,以不占用头枕区3018空间。第四线缆376电连接于操控板375与主控器371之间,实现用户通过操控板375控制显示主体32。操控板375上可以设置有按键3751。按键3751包括实体按键、触摸按键、触控屏等等。
驱动件356带动显示主体32旋转时,显示主体32相对电学部件37的各个器件的位置需不断改变以达到适配观看者的目的,即显示主体32与电学部件37之间发生相对移动,显示主体32、电学部件37之间的线缆需要冗余才能尽可能减少线缆活动,由于驱动件356、操控板375、主控器371均固定在骨架3015上,在显示主体32转动时,光源单元3随显示主体32旋转,驱动件356、操控板375、主控器371三者之间相对静止。因此,光源单元3和主控器371之间的第一线缆372与第二线缆373需要较大的冗余量,而主控器371与驱动件356之间第三线缆374的冗余量可减少,减少操控板375与主控器371之间第四线缆376冗余量线缆冗余量可减少。
本申请的一些实施方式中,如图11a所示,主控器371可通过紧固件(例如螺钉)等方式固定于骨架3015上。请参阅图11b,主控器371包括主控芯片(图未示)及保护壳3713, 保护壳3713固定套设于主控芯片外。保护壳3713上设有散热结构,用于散发主控芯片产生的热量。散热结构包括设于保护壳3713上的散热齿3716及散热通孔3717,以提高主控器371的散热效率。保护壳3713可以包括盖合于一起的上壳3718和下壳3719组成,例如,上壳3718与下壳3719可以由不同或相同工艺制成,例如,上壳3718可以为压铸壳,下壳可以为钣金壳。可以理解,本申请对保护壳3713的结构及制造工艺不作限定。
本申请对主控器371的设置位置不作限定,在本申请的其他实施方式中,主控器371还可以设置在其他位置,例如,若第一座椅300在头枕区3018的空间充裕,主控器371可以设置在外壳1的背部13上等等。主控器371与显示主体32的光源单元3可以有线通信连接也可以无线通信连接。
在本申请的其他实施方式中,第四线缆376可以省略,操控板375可以与主控器371无线通信连接,即操控板375可以为遥控器,操控板375可以布置在显示主体32的周围,也可以布置在第二座椅500的扶手处。在本申请的一些实施方式中,操控板375外部有盖板遮挡以对操控板375进行保护,操控板375还可以直接与外壳1连接。
请结合参阅图13a、图13b、图13c及图13d,本申请第二实施方式提供的第一座椅300s与第一实施方式提供的第一座椅的结构大致相同,不同在于,俯仰机构35的结构。
封装壳34包括连接设置的第一封装部341及第二封装部343,俯仰机构35还包括第一连接组件351、隔振件357及第二连接组件352。第一连接组件351至少部分收容于第一封装部341内。第一连接组件351连接于第一支撑臂313及第一侧部151之间,第二连接组件352连接于第二支撑臂315及第二侧部153之间,使支撑架31与显示主体32转动连接。传动组件353与第一连接组件351传动连接,驱动件356与传动组件353传动连接。传动组件353用于将驱动件356输出的动力传递给第一连接组件351,使显示主体32相对支撑架31转动。隔振件357位于驱动件356与骨架3015之间,用于阻断驱动件356的振动通过骨架3015传导到第一座椅300s上的乘坐者上而被乘坐者感知,从而可以做到静音调节,保证观看者对光学显示器303的沉浸式观影效果。
