本申请提供的VR头戴显示装置包括：显示模块、第一镜筒、第二镜筒和柔性密封件，柔性密封件设置在显示模块的第一面，且柔性密封件与显示模块的第一面密封连接，以使柔性密封件与显示模块的第一面之间形成密封空间，且第一镜筒和第二镜筒均设置于柔性密封件，其中，第一镜筒和/或第二镜筒能够单独在柔性密封件的一侧进行位置调节，以使第一镜筒和第二镜筒之间的距离与所述VR头戴显示装置的佩戴者的双眼之间的瞳距适配。具体而言，在调节第一镜筒和第二镜筒之间的瞳距时，可以使第一镜筒位置不动，单独调整第二镜筒的位置，也可以使第二镜筒的位置不动，单独调整第一镜筒的位置，还可以同时调整第一镜筒以及第二镜筒的位置，进而可以满足不同面型的佩戴者的需求(即可以满足左右眼完全对称的人群，也可以满足左右眼不完全对称的人群)。
需要说明的是，当第一镜筒和/或第二镜筒相对于显示模块移动时，因柔性密封件与显示模块的第一面之间形成密封的空间，以使第一镜筒和/或第二镜筒在调节瞳距时，第一镜筒、第二镜筒、柔性密封件以及显示模块的第一面还是形成了密封空间，可以防止灰尘及其他的杂质进入第一镜筒、第二镜筒、显示模块和柔性密封件形成的密封空间内。
一种可能的实施例中，为了防止第一镜筒和/或第二镜筒在移动时，第一镜筒和第二镜筒与显示模块之间产生摩擦，造成摩擦屑掉落在第一镜筒、第二镜筒与显示模块之间，可以将第一镜筒和第二镜筒穿设于柔性密封件，第一镜筒穿设在密封空间内的一端与显示模块的第一面之间存在间隙、且第二镜筒穿设在密封空间内的一端与显示模块的第一面之间存在间隙。
一种可能的实施例中，为了使第一镜筒相对于显示模块移动后的位置能够固定，VR头戴显示装置还可以包括第一限位件，第一限位件位于显示模块的第一面上，用于限制所 述第一镜筒相对于所述显示模块的位置。这样，第一限位件的位置相对于显示模块的位置不变，而第一限位件可以与第一镜筒配合，以使第一镜筒相对于显示模块移动后，能够在移动后的位置保持不动。

一种可能的实施例中，为了获取第一镜筒移动的距离，VR头戴显示装置还可以包括第一检测电路，第一检测电路与第一阻抗齿条和第一镜筒电连接，用于检测所述第一阻抗齿条和所述第一镜筒之间的电阻。这样，当第一镜筒沿第一阻抗齿条滑动时，会造成第一阻抗齿条和所述第一镜筒之间的电阻发生变化，第一镜筒每移动一个第一限位齿就可以与第一检测电路检测到的电阻值形成对应关系，根据第一检测电路检测到的电阻值的变化即可知道瞳距的变化。
在上述的实施例中，为了使第二镜筒相对于显示模块移动后的位置能够固定，VR头戴显示装置还可以包括第二限位件，第二限位件位于显示模块的第一面上，用于限制所述第二镜筒相对于所述显示模块的位置。第二限位件的位置相对于显示模块的位置不变，而第二限位件可以与第二镜筒配合，以使第二镜筒相对于显示模块移动后，能够在移动后的位置保持不动。
具体而言，第二限位件可以包括第二阻抗齿条和与第二阻抗齿条配合的多个第二限位齿，第二阻抗齿条可以与柔性密封件通过注塑一体成型，且第二阻抗齿条可以与显示模块之间固定连接，第二阻抗齿条的延伸方向和第二镜筒的移动方向所匹配，多个第二限位齿可以设置在第二镜筒位于所述密封空间内的外壁上，这样，第二镜筒在相对于显示模块的位置调节后，第二限位齿可以与第二阻抗齿条配合，以将第二镜筒的位置限定。
在一种可能的实施例中，为了获取第二镜筒移动的距离，VR头戴显示装置还可以包括第二检测电路，第二检测电路与第二阻抗齿条和第二镜筒电连接，用于检测所述第二限位件和所述第二镜筒之间的电阻。这样，当第二镜筒沿第二阻抗齿条滑动时，会造成第二阻抗齿条和所述第二镜筒之间的电阻的发生变化，第二镜筒每移动一个第二限位齿就可以与第二检测电路检测到的电阻值形成对应关系，根据第二检测电路检测到的电阻值的变化即可知道瞳距的变化。
需要说明的是，第一阻抗齿条和第二阻抗齿条的长度即为瞳距调节的范围。
在一种可能的实施例中，为了使显示模块能够更好的和VR头戴显示装置的佩戴者进行适配，在显示模块上还可以设置有第一避让部，第一避让部设置在第一镜筒和第二镜筒之间，第一避让部可以与佩戴者的鼻子的位置对应。需要说明的是，在柔性密封件上还可以设置有第二避让部，第二避让部可以与第一避让部对应，以便于佩戴者佩戴。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
现有的VR头戴显示装置中可以具有一个显示屏或者两个显示屏，一个显示屏需要一个显示驱动芯片，目前，半导体行业硅基片产能供不应求，导致显示驱动芯片的价格不断的增加，因此，一个显示屏的VR头戴显示装置的成本优势越来越明显。但是，一个显示屏的VR头戴显示装置中的显示屏需要调节两个镜筒之间的瞳距，现有技术中，两个镜筒在移动时，均以鼻梁为中心做对称的移动，进而不能够满足左右眼不完全对称的人群使用。
为此，本申请提供一种VR头戴显示装置，以解决上述的问题。
以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外 一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
参照图1，本申请实施例提供了一种VR头戴显示装置，VR头戴显示装置可以包括显示模块10、第一镜筒30、第二镜筒40和柔性密封件20，其中，显示模块10具有用于设置柔性密封件20的第一面，柔性密封件20与显示模块10的第一面密封连接，以使柔性密封件20与显示模块10的第一面之间形成密封空间，第一镜筒30和第二镜筒40均设置于柔性密封件20；其中，第一镜筒30和第二镜筒40可在柔性密封20件的一侧进行位置调节，以使第一镜筒30和第二镜筒40之间的距离与所述VR头戴显示装置的佩戴者的双眼之间的瞳距适配。在调节第一镜筒30和第二镜筒40之间的瞳距时，可以同时调节第一镜筒30和第二镜筒40相对于显示模块10上的位置，或者，也可以使第一镜筒30的位置不变化，单独的调节第二镜筒40相对于显示模块10上的位置，以调节第一镜筒30和第二镜筒40之间的瞳距，或者使第二镜筒40的位置不变化，单独的调节第一镜筒30相对于显示模块10上的位置，以调节第一镜筒30和第二镜筒40之间的瞳距，通过单独调节第一镜筒30和/或第二镜筒40的位置，可以满足不同面型的佩戴者的需求(即可以满足左右眼完全对称的人群，也可以满足左右眼不完全对称的人群)。
需要说明的是，在具体设置显示模块10时，为了实现显示模块10与VR头戴显示装置的佩戴者进行适配，可以在显示模块10上设置有第一避让部11，第一避让部11可以设置在第一镜筒30和第二镜筒40之间，第一避让部11可以避让VR头戴显示装置的佩戴者的鼻子，以便于VR头戴显示装置佩戴于VR头戴显示装置的佩戴者的头部。另外，在具体设置柔性密封件20时，柔性密封件20上也需要设置有第二避让部21，第二避让部21与第一避让部11相对应，第二避让部21也是用于避让鼻子，以便于VR头戴显示装置的佩戴者佩戴VR头戴显示装置，而且由于第一避让部11和第二避让部21的设置，可以降低VR头戴显示装置的重量，使VR头戴显示装置的成本降低，还使VR头戴显示装置变得轻薄。
其中，柔性密封件20的材料可以是聚酯纤维，聚酯纤维具体可以、但不限制为涤纶或棉纶，若需要增加柔性密封件20的弹性，可以在聚酯纤维中增加氨纶材料。
在上述的实施例中，第一镜筒30和/或第二镜筒40相对于显示模块10移动时，第一镜筒30和/或第二镜筒40会带动柔性密封件20摆动，且第一镜筒30、第二镜筒40、柔性密封件20与显示模块10的第一面之间形成密封空间，以使第一镜筒30和/或第二镜筒40在调节瞳距时，第一镜筒30、第二镜筒40、显示模块10和柔性密封件20形成的密封空间内不会进入杂质。
图2为第一镜筒30和第二镜筒40之间的瞳距最大时VR头戴显示装置的俯视图，图3为将第一镜筒30向远离第二镜筒40的一端移动后的VR头戴显示装置的俯视图，请参照图2和图3，第一镜筒30的第一端位于密封空间中，第一镜筒30的第二端穿过密封空间向远离显示模块10的一侧延伸，第二镜筒40的第一端位于密封空间中，第二镜筒40的第二端穿过密封空间向远离显示模块10的一侧延伸，其中，第一镜筒30的第一端与显示模块10之间存在间隙，该间隙的设置可以防止第一镜筒30移动时，第一镜筒30与显示模块10之间产生摩擦，造成摩擦屑掉落在第一镜筒、第二镜筒、显示模块和柔性密封件形成的密封空间内；同样的，第二镜筒的第一端与显示模块之间也存在间隙，该间隙的 设置可以防止第二镜筒移动时，第二镜筒与显示模块之间产生摩擦，造成摩擦屑掉落在第一镜筒、第二镜筒、显示模块和柔性密封件形成的密封空间内。
图4为VR头戴显示装置没有展示显示模块的主视图，图5为VR头戴显示装置第一镜筒30和第二镜筒40之间瞳距最大的主视图，图6为VR头戴显示装置第一镜筒30和第二镜筒40之间瞳距最小的主视图，请参照图4～图6，为了使第一镜筒30在相对于显示模块10移动后的位置能够固定，保证第一镜筒30移动后位置的稳定，VR头戴显示装置还可以包括第一限位件50，第一限位件50可以设置在显示模块10的第一面上，第一限位件50的位置相对于显示模块10的位置不变，第一限位件50可以与第一镜筒30配合，以使第一镜筒30相对于显示模块10移动后，第一镜筒30能够与第一限位件50配合，保证移动后的第一镜筒30的位置不变。
第一限位件50可以包括第一阻抗齿条51和多个第一限位齿52，其中，第一阻抗齿条51可以设置在柔性密封件20上，且第一阻抗齿条51与显示模块10的第一面之间固定连接，第一阻抗齿条51的延伸方向与第一镜筒30的移动方向相同，第一阻抗齿条51可以与柔性密封件20通过注塑一体成型，多个第一限位齿52可以设置在第一镜筒30位于密封空间内的外壁上，这样，第一镜筒30在相对于显示模块10的位置调节后，第一镜筒30上的第一限位齿52可以与第一阻抗齿条51配合，以将第一镜筒30的位置限定。
参照图7～图9，VR头戴显示装置还包括用于检测第一阻抗齿条51和第一镜筒30之间的电阻的第一检测电路70，第一检测电路70与第一阻抗齿条51和第一镜筒30电连接，这样，第一镜筒30移动时，会造成第一阻抗齿条51和第一镜筒30之间的电阻值变化，具体而言，第一镜筒30向左滑动时，第一阻抗齿条51和第一镜筒30之间的电阻的阻值会减小；第一镜筒30向右滑动时，第一阻抗齿条51和第一镜筒30之间的电阻的阻值会增加。如图9所示，第一阻抗齿条51上设置有多个锯齿，每个锯齿均可以与第一限位齿52配合，由于第一镜筒30相对于第一阻抗齿条51每移动一个锯齿的距离，第一阻抗齿条51和第一镜筒之间的电阻的阻值就会随之变化，而第一阻抗齿条51的长度确定，移动的每个锯齿的距离也为定值，进而可以根据电阻值的变化而得到瞳距的变化，即第一阻抗齿条51和第一镜筒30之间的电阻的每个电阻值对应一个瞳距。
需要说明的是，第一阻抗齿条、第一限位齿、第一镜筒以及第一检测电路70可以等效为图10中的电路图，其中，虚线框中的结构即为第一阻抗齿条、第一限位齿和第一镜筒形成的结构。
请继续参照图4～图6，为了使第二镜筒40相对于显示模块10移动后的位置能够固定，VR头戴显示装置还可以包括第二限位件60，第二限位件60位于显示模块10的第一面上，且第二限位件60的位置相对于显示模块10的位置不变，而第二限位件60可以与第二镜筒40配合，以使第二镜筒40相对于显示模块10移动后，能够在移动后的位置保持不动。
第二限位件60可以包括第二阻抗齿条61和多个第二限位齿62，其中，第二阻抗齿条61可以设置在柔性密封件20上，且第二阻抗齿条61与显示模块10的第一面之间固定连接，第二阻抗齿条61的延伸与第二镜筒40的移动方向相同，第二阻抗齿条61可以与柔性密封件20通过注塑一体成型，多个第二限位齿62可以设置在第二镜筒40位于密封空间内的外壁上，这样，第二镜筒40在相对于显示模块10的位置调节后，第二镜筒40上的第二限位齿62可以与第二阻抗齿条61配合，以将第二镜筒40的位置限定。
VR头戴显示装置还包括用于检测第二限位件60和第二镜筒40之间的电阻的第二检 测电路(图中未示出)，第二检测电路与第二阻抗齿条61和第二镜筒40电连接，这样，第二镜筒40移动时，会造成第二限位件60和第二镜筒40之间的电阻值的变化，具体而言，第二镜筒向左滑动时，第二阻抗齿条61和第二镜筒40之间的电阻的阻值会减小；第二镜筒40向右滑动时，第二阻抗齿条61和第二镜筒40之间的电阻的阻值会增加，第二阻抗齿条61上设置有多个锯齿，每个锯齿均可以与第二限位齿62配合，由于第二镜筒40相对于第二阻抗齿条61移动一个锯齿的距离，第二阻抗齿条61和第二镜筒40形成的电阻的阻值就会随之变化，而第二阻抗齿条61的长度可以确定，移动每个锯齿的距离也为定值，进而可以根据电阻值的变化而得到瞳距的变化，即第二阻抗齿条61和第二镜筒40之间的电阻的每个电阻值对应一个瞳距。
继续参照图11a和图11b，图11a为第一镜筒30和第二镜筒40之间的瞳距最小的示意图，图11b为第一镜筒30和第二镜筒40之间的瞳距最的示意图，如图11a和图11b所示，柔性密封件20与显示模块10的连接处并不产生变化，进而可以保证，无论第一镜筒30和第二镜筒40如何调整，柔性密封件20与显示模块10之间密封连接。
参照图12，在上述实施例中，VR头戴显示装置通常还包括处理器80、传感器模块90、麦克风100、通信模块110以及摄像头120、存储器81，所述处理器80与上述实施例中的显示模块、传感器模块90、麦克风100、通信模块110以及摄像头120、存储器81电连接。此外，VR头戴显示装置通常还包括电池82、按键83以及一个或多个输入输出接口84，第一镜筒和第二镜筒可以形成眼动追踪模组130，眼动追踪模组130也与处理器80电连接。
其中，按键83用于用户输入指令或信息，传感器模块90可以用于获取用户的姿态；
处理器80通常用于控制VR穿戴显示装置的整体操作，处理器80可以包括一个或多个处理单元，例如：处理器80可以包括应用处理器80(applicationprocessor，AP)、调制解调处理器80、图形处理器80(graphicsprocessingunit，GPU)、图像信号处理器80(imagesignalprocessor，ISP)、视频处理单元(videoprocessingunit，VPU)控制器、存储器81、视频编解码器、数字信号处理器(digitalsignalprocessor，DSP)、基带处理器，和/或神经网络处理器80(neural-networkprocessingunit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器80中。
存储器81用于存储指令和数据。在一些实施例中，VR穿戴显示装置中的存储器81可以为高速缓冲存储器81。该存储器81可以保存处理器80刚用过或循环使用的指令或数据。如果处理器80需要再次使用该指令或数据，可从所述存储器81中直接调用。避免了重复存取，减少了处理器80的等待时间，因而提高了系统的效率。
在本申请的一些实施例中，处理器80可以用于控制VR穿戴显示装置的光焦度。示例性的，处理器80可以用于控制显示模块10的光焦度，实现对VR穿戴显示装置的光焦度的调整的功能。例如，处理器80可以通过调整显示模块10中各个光学器件(如镜筒中的透镜等)之间的相对位置，使得显示模块10的光焦度得到调整，进而使得显示模块10在向人眼成像时，对应的虚像面的位置可以得到调整。从而达到控制VR穿戴显示装置的光焦度的效果。
在一些实施例中，处理器80可以包括一个或多个输入输出接口84。输入输出接口84可以包括集成电路(inter-integratedcircuit，I2C)接口、通用异步收发传输器(universalasynchronousreceiver/transmitter，UART)接口、移动产业处理器80接口(mobileindustryprocessorinterface，MIPI)、通用输入输出(general-purposeinput/output， GPIO)接口、用户标识模块(subscriberidentitymodule，SIM)接口、和/或通用串行总线(universalserialbus，USB)接口、串行外设接口(serialperipheralinterface，SPI)接口等。
I2C接口是一种双向同步串行总线，包括一根串行数据线(serialdataline，SDA)和一根串行时钟线(derailclockline，SCL)。在一些实施例中，处理器80可以包含多组I2C总线。
UART接口是一种通用串行数据总线，用于异步通信。该总线可以为双向通信总线。它将要传输的数据在串行通信与并行通信之间转换。在一些实施例中，UART接口通常被用于连接处理器80与通信模块110。例如：处理器80通过UART接口与通信模块110中的蓝牙模块通信，实现蓝牙功能。
MIPI接口可以被用于连接处理器80与显示模块10，摄像头120等外围器件。
GPIO接口可以通过软件配置。GPIO接口可以被配置为控制信号，也可被配置为数据信号。在一些实施例中，GPIO接口可以用于连接处理器80与摄像头120、显示模块10、通信模块110、传感器模块90、麦克风100等。GPIO接口还可以被配置为I2C接口，I2S接口，UART接口，MIPI接口等。在一些实施例中，摄像头120可以采集包括真实对象的图像，处理器80可以将摄像头120采集的图像与虚拟对象融合，通过显示模块10现实融合得到的图像。在一些实施例中，摄像头120还可以设置在第一镜筒和第二镜筒上，以采集包括人眼的图像，形成眼动追踪模组130。处理器80通过所述图像进行眼动追踪。
USB接口是符合USB标准规范的接口，具体可以是MiniUSB接口、MicroUSB接口、USBTypeC接口等。USB接口可以用于连接充电器为VR穿戴显示装置中的电池82充电，也可以用于VR穿戴显示装置与外围设备之间传输数据。也可以用于连接耳机，通过耳机播放音频。该接口还可以用于连接其他电子设备，例如手机等。USB接口可以是USB3.0，用于兼容高速显示接口(displayport，DP)信号传输，可以传输视音频高速数据。
为了使摄像头的拍摄位置随着第一镜筒和第二镜筒的移动而变化，实现显示模块的画面显示中心随第一镜筒和第二镜筒的瞳距的调节而相应移动，保证不同瞳距的人群观看效果相同。具体的，参照图13，在图13中，l为左，r为右，t为上，b为下，n为近裁切面的z向坐标，f为远裁切面的z向坐标，由于第一镜筒和第二镜筒沿水平方向移动，故第一镜筒和第二镜筒移动时，如下矩阵中对应的l和r的值随之变化，当第一镜筒和第二镜筒之间的瞳距变化(变大)，且变化值为m时，对应的左眼中的映射矩阵中的原l变化为l-m，原r变化为r-m，右眼中的映射矩阵中的原l变化为l+m，原r变化为+m，将变化后的值代入矩阵公式中即可。同样的，当第一镜筒和第二镜筒之间的瞳距变化(变小)，且变化值为m时，对应的左眼中的映射矩阵中的原l变化为l+m，原r变化为r+m，右眼中的映射矩阵中的原l变化为l-m，原r变化为-m，将变化后的值代入矩阵公式中即可。
上述的矩阵公式为：
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
