Description

头戴式显示设备 技术领域
本发明涉及显示设备技术领域,特别涉及一种头戴式显示设备。
背景技术
虚拟显示技术是通过计算机或移动终端等设备虚拟出现实世界,通过显示屏和目视系统投射到人眼视网膜。其本质就是呈现一个以使用者视角为主体,可以实时无限制地观察三维空间内的物体,给使用者沉浸感体验。虚拟显示技术已经广泛应用在娱乐,军事训练,医疗培训、产品三维虚拟展示等多个领域。
用户通常借助头戴式显示产品(例如VR眼镜)来观看由虚拟现实技术而产生的逼真画面。然而,目前大多数的头戴式显示产品,尤其是有户外使用情景的头戴式显示产品,不管是在常温还是高温天气,由于头戴式显示产品在佩戴时为保证观看的体验,不能漏光,要求眼镜部分的密封性较好,这就导致使用者在长时间佩戴头戴显示产品后,使用者脸部闷热,很容易出汗和散发出热量,导致空气中的湿度增加,较热的湿气接触到温度较低的镜片后,容易在镜片起雾和产生雾气,最终影响用户的观看体验。

针对目前用户在长时间佩戴头戴显示产品后,容易出汗导致在镜片上产生雾气,影响用户观看体验的问题,本发明提供一种头戴式显示设备。下面结合附图,对本发明的头戴式显示设备进行详细说明。在不冲突的情况下,下述的实施例及实施方式中的特征可以相互组合。
参见图1至图3所示,本发明实施例提供的一种头戴式显示设备,包括:眼镜主体10、光学部件200以及散热风扇40。所述眼镜主体10包括收容空间,所述光学部件200设置于所述收容空间内,将所述收容空间分隔形成第一收容腔110和用于与佩戴者佩戴配合的第二收容腔120。所述光学部件200上设有导风部310,所述散热风扇40设置于所述第一收容腔110内,并与所述导风部310的位置对应设置。优选地,所述光学部件200包括眼镜罩30和装设于所述眼镜罩30的镜片20,所述眼镜罩30将所述收容空间分隔形成所述第一收容腔110和所述第二收容腔120,并且所述导风部310开设于所述眼镜罩30。
由上述实施例可知,本发明的头戴式显示设备,佩戴者使用时面部与眼镜主体10的第二收容腔120共同形成一个相对密闭的空间,当佩戴者出汗后会导致密闭的空间内空气中的湿度增加,通过散热风扇40和开设于光学部件200的眼镜罩30上的导风部310配合抽风, 使密闭的空间内的空气形成对流起到散热的作用,防止由于闷热而造成较热的湿气接触到温度较低的镜片20后,在镜片20上产生水汽或雾气,保证用户的观看体验。另外,在密闭的空间内产生对流的空气同样能够促进佩戴者面部空气流通,保证用户保持良好的体感舒适度。
参见图4并结合图1至图3所示,在一可选的实施方式中,所述眼镜主体10的一端设有开口,所述光学部件200的眼镜罩30与所述眼镜主体10上未形成所述开口一侧的壳体部分101,102,103共同围合形成所述第一收容腔110,所述光学部件200的眼镜罩30与所述眼镜主体10上形成有所述开口一侧的壳体部分104,105共同围合形成所述第二收容腔120。所述眼镜主体10在形成有所述开口一侧的壳体部分104,105的端部沿所述第二收容腔120的外周设置有一圈佩戴部130及凹陷形成于佩戴部130的鼻托部140,所述佩戴部130用于与佩戴者的面部佩戴配合,所述鼻托部用于与佩戴者的鼻部佩戴配合,佩戴者使用时将面部与所述佩戴部130及鼻托部140贴合配合,进而使佩戴者的面部与所述第二收容腔120共同形成一个相对密闭的空间,保证用户观看时不会发生漏光的情况。所述第一收容腔110内可以设置头戴式显示设备中所配备的电子元件(如电路板、电池、处理主板等),当然,这些电子元件的安装位置需要避开所述镜头20的观看视角范围,这样既保证了头戴式显示设备的整体外观美观和正常运行需求,又不会影像到用户的正常观看体验。
进一步地,所述佩戴部130的外周面上还设有用以与佩戴者的面部贴合的面罩(类似垫圈),以便佩戴者进行佩戴。可选地,所述佩戴部130的外周面设有多个用于安装所述面罩的安装孔。所述面罩包括但不仅限于泡棉类面罩,以提高佩戴者佩戴时的舒适度。
在一可选的实施方式中,所述光学部件200的眼镜罩30包括用于装设所述镜片20的镜片安装部320,为了针对容易因为闷热引起出汗的眼部位置周围起到更好的散热效果,所述导风部310设置在所述眼镜罩30上的位置位于所述镜片安装部320的上方。这样既不影像到用户的正常观看体验,又可以加强用户的眼部周围的空气流动, 对容易因为闷热引起出汗的眼部位置周围起到更好的散热效果,防止在镜片20上产生水汽或雾气。
在本实施例中,所述镜片20为两个,相应地,所述镜片安装部320为两个,所述导风部310为两个,所述散热风扇40为两个。所述两个镜片20分别装设于所述两个镜片安装部320,所述两个导风部310设置在所述眼镜罩30上的位置分别位于所述两个镜片安装部320的上方,所述两个散热风扇40设置在所述第一收容腔110内的位置分别与所述两个导风部310的位置对应设置。这样,同样不影像到用户的正常观看体验,又可以加强用户双眼周围的空气流动,对用户的双眼周围均起到更好的散热效果,防止在镜片20上产生水汽或雾气。
为了使密闭的空间内的空气流动更为均匀,所述导风部310可以包括多个导风孔311,所述多个导风孔311间隔设置。通过间隔设置的多个导风孔311能够分散密闭的空间内的空气流动,提高空气的流动性,同时也不会在眼镜罩30上形成过多的空隙而引起漏光的问题。进一步地,所述多个导风孔311沿横向及纵向(即眼镜罩30的长度方向和宽度方向)呈阵列布设,提高沿眼镜罩30的横向范围和纵向范围的空气的流动性,进一步防止在镜片20上产生水汽或雾气。
在一可选的实施方式中,结合图3所示,所述散热风扇40包括进风口410和出风口420,所述进风口410与设于所述眼镜罩30的导风部310相连通并保持一致,通过所述导风部310和所述散热风扇40的进风口410的配合将密闭的空间内的空气引至散热风扇40。在本实施例中,所述散热风扇40为轴抽风扇,所述出风口420的出风方向(如图3中Y方向所示)与所述进风口410的进风方向(如图3中X方向所示)垂直设置,由图3中可知,所述导风部310的导风方向与所述镜片20的镜面方向垂直设置,也就是说,通过所述导风部310和所述散热风扇40的进风口410的配合能够将密闭的空间内的空气横向流动至散热风扇40,再通过散热风扇40将气流沿纵向从所述出风口420排出,如图3中箭头方向所示。因此,所述散热风扇40采用轴抽风扇,能够有效加强空气的对流性。可选地,所述 眼镜主体10的壳体上相对所述散热风扇40的出风口420的位置可以设置多个排气孔,使散热风扇40排出的空气由所述排气孔排出眼镜主体10,进一步促进空气循环。
在一可选的实施方式中,所述头戴式显示设备的电子元件包括电路板、电池等发热元件50,所述发热元件设置在所述第一收容腔110内,所述散热风扇40的出风口420朝向所述发热元件50设置。在头戴式显示设备的使用过程中,这些发热元件50会发散大量热量,因此将所述散热风扇40的出风口420朝向所述发热元件50设置,从散热风扇40的出风口420排出的气流可以吹向发热元件50进而对发热元件50进行散热。即散热风扇40不仅能够增加密闭的空间内的空气流动以防止由于闷热而造成较热的湿气接触到温度较低的镜片20后产生水汽或雾气,同时还能兼顾为发热元件50进行散热。
进一步地,所述发热元件50上设置安装结构,所述散热风扇40设置于所述安装结构上,更有利于对发热元件50进行散热。在本实施例中,所述散热风扇40设置于发热元件50的下方,便于从出风口420排出的空气能够直接对发热元件50进行散热。另外,散热风扇40工作时会产生一定程度的噪音和震动,为了降低散热风扇40产生的噪音和震动,所述散热风扇40与所述安装结构之间设有减震垫60,能够帮助降低散热风扇40工作时的噪音和震动。可选地,所述减震垫60采用但不仅限于海绵垫,海绵垫可以采用透气性较高的材质,不影响散热风扇40的排风效果。当然,也可用其它透气性较好的且较为柔软的材料替代海绵垫。
参见图5所示,在一可选的实施方式中,所述头戴式显示设备还包括头戴部70,所述头戴部70可拆卸连接于所述眼镜主体10上,用于配合所述佩戴部130将所述眼镜主体10与佩戴者固定。佩戴者使用所述头戴式显示设备时,将所述头戴部70套在头上,再将所述佩戴部130贴合在面部,从而将所述头戴式显示设备进行固定。可选地,所述眼镜主体10上设有用于连接所述头戴部70的插接部150,所述头戴部70上设有与所述插接部150配合连接的插接件,实现将所述头戴部70可拆卸连接于所述眼镜主体10上,便于收纳。例如, 可以在眼镜主体10的插接部150上设置与所述插接件卡接配合的凹槽或者卡接孔,在头戴部70的插接件上设置弹性按钮。在需要拆卸所述头戴部70时,按下所述弹性按钮,即可将所述插接件从所述眼镜主体10的插接部150中退出,从而将头戴部70与眼镜主体10分离。在本实施例中,所述插接部150设置在眼镜主体10的顶部,便于与头戴部70配合使用。
在一实施方式中,所述头戴式显示设备为VR(Virtual Reality,虚拟现实技术)眼镜、AR(Augmented Reality,增强现实技术)眼镜或FPV(First Person View,第一人称主视角)眼镜。
以上所述仅是本发明的较佳实施例而已,并非对本发明做任何形式上的限制,虽然本发明已以较佳实施例揭露如上,然而并非用以限定本发明,任何熟悉本专业的技术人员,在不脱离本发明技术方案的范围内,当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明技术方案的范围内。
