下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动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。
本实施例中的虚拟现实设备包括壳体、内置于壳体的光学系统、PCBA板、散热板和光感组件、与壳体配合使用的脸托、遮光罩等。下面针对各部件进行详细说明。
一、壳体:如图1所示,壳体包括:前壳1与后壳3围成的镜框、与镜框连接的左镜腿5和右镜腿4。下面分别针对上述部件进行详细说明:
(1)前壳1:如图2所示,前壳1的周边设有若干卡扣固定件16,用来将前壳1与后壳3固定;靠近前壳1的上端设有PCBA固定件18,用来对PCBA板8进行限位和固定;在靠近前壳1两端附近安装保护柱17,用来防止安装过程或者安装好后前壳受力过猛损坏前壳1。进一步的,为了提高前壳1的质量,还可以设置多条加固条纹。为了减轻虚拟现实设备的壳体重量,前壳1的材质优选轻质塑料,为了便于加工,整个前壳1优选设计为一体成型。
(2)后壳3:如图3(a)和图3(b)所示,后壳3包括收纳腔46,用来收纳虚拟现实设备的光学系统、PCBA板8、散热片9和光感组件等。后壳3的下端设有调节槽42,用于伸出光学系统的焦距调节键(等同于下文的定位特征件、凸出控制键)并对其进行控制。后壳3内部偏上位置设有与前壳1相配合的PCBA固定槽。为了提高后壳3的质量,还可以设置多条加固条纹,优选的设置在后壳的侧边。在后壳3的背面设有镜脚连接部,镜脚连接部上设有与左镜腿5和右镜腿4前端的凸起连接的凹槽44,凹槽44的外侧设有挡板45。由于凹槽44外侧具有一个挡板45,当镜腿的凸起装配到该凹槽中时,此时的镜腿只能向内侧移动。当用户配戴该虚拟现实设备时,镜腿的凸起会受到挡板45的阻挡,阻止其向外移动,这时就会向内产生一个力,让镜腿能够夹紧用户头部。在后壳3的背面还设有脸托固定件41和43,用来便于脸托6的固定。如图4和图14所示,脸托6包括主体固定部64和面部接触部63,面部接触部63一侧与主体固定部64连接,另一侧与人体面部相接触,主体固定部64上设有用于嵌入脸托固定件41和43的凸起61和62,实现主体固定部64固定在后壳3上。为了便于脸托6能分散虚拟现实设备的重量,主体固定部64和面部接触部63均为由位于中心的向外凸起的凸缘和沿远离凸缘方向延伸的弧形部组成的几字形结构。为了减轻虚拟现实壳体主体的重量,后壳3优选轻质塑料,为了便于加工,后壳3优选设计为一体成型。
(4)左镜腿5和右镜腿4:将左镜腿5和右镜腿4统称为镜腿,两者结构无实质差别。每一镜腿前端设有用于嵌入后壳3上镜脚连接部上凹槽的凸起53。下面以左镜腿5为例进行详细说明。如图5所示,非折合状态下,左镜腿5和右镜腿4为向内弯曲的弧形,便于夹紧使用者头部。为了进一步增强镜腿的夹紧力度,镜腿前端的厚度大于镜脚后端厚度。为了减轻镜腿的重量,镜腿上还设有镂空槽52,同时镂空槽52也可以防止注塑表面产生缺陷,影响美观。左镜腿5和右镜腿4上还分别设有通孔51,用于将遮光组件7的凸起71和72嵌入通孔51,实现遮光组件7的固定。通孔具体包括两个相通的固定孔和连接孔,连接孔的孔径大于连接件的最大宽度,固定孔的孔径小于连接件的最大宽度。固定孔用来固定遮光组件的凸起,连接孔用来遮光组件的凸起穿过定位。左镜腿5和右镜腿4均可为一体成型机构,为了减轻整体虚拟现实设备的整体重量,左镜腿5和右镜腿4的材质为具有柔韧性塑胶(TR90)。结合图1所示,上述虚拟现实设备的壳体和其他组件的具体安装步骤如下:
第一步:将带有左显示屏22、右显示屏24的左镜筒机构21、右镜筒机构23的光学系统装入后壳3的收纳腔46中进行固定,不限定具体固定方式。左镜筒机构21、右镜筒机构23的定位特征件同时伸出后壳3的调节槽42,便于用户来进行调节焦距;
第二步:将PCBA板8装入后壳3的PCBA固定槽中,并将PCBA板8与光学系统进行连接;
第三步:装入散热片9,具体将散热片9一端与PCBA板8上的发热器件贴合,另外一端分别与左显示屏22和右显示屏24的背面贴合,使得散热片9就可以将PCBA板8和左显示屏22和右显示屏24散发的热量均匀散出;
第四步:装上前壳1,即将前壳1与后壳3进行固定,具体的将前壳1压入后壳3中,通过前壳1的扣固定件11进行固定;
第五步:将左镜腿5和右镜腿4上的凸起53嵌入后壳3上的凹槽44;
第六步:将脸托6安装到后壳3上,具体的将脸托6上的凸起61和62分别与后壳3上的脸托固定件41和43进行固定;
第七步:将遮光组件7包围虚拟现实设备,同时将遮光组件的,具体的遮凸起71和72分别嵌入镜腿的通孔51上。
上述虚拟现实设备包括前壳、后壳和两个镜腿,结构简单,组装简便,同时将虚拟现实设备的其他器件对应的安装在后壳的收纳槽上,盖上前壳和连接镜腿,整个虚拟现实设备结构比较小,占用空间较小,外形类似眼镜形态,比较美观。
(二)光学系统:如图1所示,光学系统包括左镜筒机构21、左显示屏22、右镜筒机构23和右显示屏24,左镜筒机构21和右镜筒机构23结构相同,统称为光学镜片调焦组件。具体的,左镜筒机构21和左显示屏22安装在左屏支架上且左显示屏22位于左镜筒机构21的后方,左显示屏整体位于左屏支架的内侧;右镜筒机构23和右显示屏24安装在右屏支架13上且右显示屏24位于右镜筒机构23的后方,右显示屏24整体位于右屏支架13的内侧。左显示屏22和右显示屏24的侧边沿具有切角,如图1所示,左显示屏22的右下角侧边具有切角。右显示屏24的左下角侧边具有切角。左屏支架和右屏支架13为两个相互独立的屏支架,均为一中空环状结构。由于两个屏支架中空,实现了通过左镜筒机构21和右镜筒机构23的镜片观看对应显示屏所显示的内容。屏支架的中空环状可为圆形或多边形或不规则形形状,具体根据光学模组的形状和虚拟现实设备外壳的形状确定。各屏支架与显示屏接触的面为屏接触面,屏接触面用于与显示屏表面相贴合,具体可设为光滑面,将屏接触面设为光滑面,可为避免显示屏造成损坏,同时也实现了显示屏与屏支架的良好贴合。本实施例中不具体限定屏接触面为光滑面或粗糙面。本实施例中,为了更好的实现屏接触面与显示屏表面的贴合,可以在两者之间设置软性的双面粘贴胶,双面粘贴胶可以为屏支架形状相对应的环形圈,通过双面粘贴胶使屏支架与显示屏粘贴在一起。与屏接触面相对应的为光学模组接触面,光学模组接触面分别与左镜筒机构21、右镜筒机构23相贴合。当屏支架分别与显示屏和光学模组组装后,屏支架起到便于安装的作用,同时三者形成密闭空间,起到防尘作用。为了进一步提高屏支架与显示屏和光学模组之间的防尘效果,右镜腿4屏支架靠近右镜腿4屏接触面的一侧设有第一凹槽,右镜腿4屏支架靠近右镜腿4光学模组接触面的一侧设有第二凹槽,右镜腿4第一凹槽和右镜腿4第二凹槽内均用于放置防尘圈,实现屏支架与光学模组、显示屏之间连接无空隙,进而避免外界的灰尘进入,提高其的防尘效果。需要说明的是,也可在不用防尘圈的情况下直接将显示屏和光学模组固定在屏支架上。由于左屏支架与右屏支架的安装相似,下面以右显示屏24、右镜筒机构23和右屏支架13的安装步骤进行说明,应该理解为左眼显示屏的安装相似,具体安装步骤如下:
第一步:在屏支架13的相对设置的屏接触面和光学模组接触面上分别固定左防尘圈12、右防尘圈14(左、右仅仅是结合附图进行区别,不具有实际含义),屏支架13、左防尘圈12和右防尘圈14组装成屏支架组件。左防尘圈12和右防尘圈14的固定方式可根据实际需要设置,不具体限定。优选为粘贴固定,左防尘圈12和右防尘圈14可为具有粘贴性的双面胶片,屏支架13上设有第一凹槽和第二凹槽,第一凹槽位于靠近屏接触面的一侧并与左防尘圈12的形状相对应,第二凹槽位于靠近光学模组接触面的一侧并与右防尘圈14的形状相对应,便于提高防尘效果以及节约材料。需要说明的是,双面胶片只是左防尘圈12和右防尘圈14可选的一种具体材料,任何具有粘贴性并且可以进行软性收缩的材料都 可以,比如塑料或具有一定软性的PORON或一定软性的PVC或轻薄的布料等;当然,为了减轻虚拟现实设备的整体重量,左防尘圈12和右防尘圈14优选质轻材料。同理,为了减轻虚拟现实设备的整体重量,屏支架13可一体成型,屏支架13的材料可选择轻质材料,如具有一定硬度的塑胶。
第二步:将右镜筒机构23和右显示屏24分别与屏支架组件进行固定。具体的,将右镜筒机构23放置到右防尘圈14上,优选的,右镜筒机构23可以放置在第二凹槽上,该右防尘圈14一侧与屏支架13接触,另一侧与右镜筒机构23接触。具体的,将右显示屏24放置到左防尘圈12上,优选的,右显示屏24可以放置在第一凹槽上,实现右显示屏24与屏支架13的固定。该左防尘圈12一侧与屏支架13接触,另一侧与右显示屏24接触。将右镜筒机构23和右显示屏241优选的固定在屏支架13两侧的第一凹槽和第二凹槽时,右显示屏24、屏支架13和右镜筒机构23之间能够形成密闭空间,其连接处都是紧密连接,并且具有凹槽的侧边进行防尘,这样就可以避免外界的灰尘进入到该密闭空间中,也就是说避免外界灰尘进粘附到显示屏上,造成显示屏上显示出现杂像的问题。
第三步:当右镜筒机构23、左防尘圈12、屏支架13、右防尘圈14和右镜筒机构23组装完成后,通过屏支架13上的屏固定孔与虚拟现实设备对应的第二固定孔匹配,实现组装后的组件固定到虚拟现实设备上,此固定方式不局限于螺钉固定方式。需要说明的是,屏支架13上的屏固定孔包括至少一个正向孔和至少一个反向孔。
如图22(a)(b)所示,屏支架的结构为:两个屏支架相互独立,光学模组接触面上设有沿远离其表面方向延伸光学模组固定件111和定位件113,当光学模组伸入屏支架并凸出于光学模组接触面时,光学模组固定件111与光学模组的最外边相接触,用于将光学模组固定在屏支架上,光学模组固定件111可以为向屏支架中心延伸的L形结构,用于将光学模组限定在L形结构内;定位件113位于光学模组的外围,用于确保光学模组安装在预设位置,用于限定光学模组的运动轨迹,定位件113用来防止光学模组向外移动。为了便于虚拟现实设备一些其他小电子件的固定,例如光感器,在屏支架的一侧凸出一个对应的收纳固定槽114,用来对其他小电子器件的固定。当显示屏、左防尘圈、屏支架、右防尘圈和光学模组组成完成后,通过屏支架上的屏固定孔112与虚拟现实设备对应的第二固定孔匹配,实现组装后的组件固定到虚拟现实设备上,此固定方式不局限于螺钉固定方式。需要说明的是,屏支架上的屏固定孔112包括至少一个正向孔和至少一个反向孔。如图10至图13所示,左镜筒机构和右镜筒机构统称为的光学镜片调焦组件均包括:外镜筒211、外光学镜片212、内镜筒214和内光学镜片217,外光学镜片212固定在外镜筒211上,内光学镜片217固定在内镜筒214上;外镜筒211侧壁上设有倾斜槽213;内镜筒214设置在外镜筒211内,内镜 筒214的侧壁上设有定位特征件,定位特征件还伸入倾斜槽213并沿倾斜槽213滑动;当内镜筒214沿外镜筒211相对滑动时,固定在外镜筒211上的外光学镜片212与固定在内镜筒214上的内光学镜片217之间的距离可调,实现了光学组件的调焦。如图10所示的光学调焦组件的爆炸图,包括一个外镜筒211、外光学镜片212、内镜筒214、内光学镜片217、两个第一防尘件218、第一防尘件219、两个固定螺钉220、拨动固定螺钉221和拨动固定螺钉221。下面分别针对上述各部件进行说明:
(1)外镜筒211:该外镜筒211侧壁上设有至少一个倾斜槽213,倾斜槽213相对于水平面以一定角度倾斜,当固定在内镜筒214侧壁上的定位特征件嵌入倾斜槽213并沿倾斜槽213移动时,外光学镜片212与内光学镜片217之间的间距可调。如图1所示,外镜筒211横截面的形状为圆形,当倾斜槽213数量为三个以上时,倾斜槽213沿外镜筒211周向均布。需要说明的是,倾斜槽213不局限于图中所示的三个,优选的,倾斜槽213的数量为三个。此外,倾斜槽213也不仅限于沿外镜筒211周向均布,但必须满足若干个倾斜槽213位于同一水平面上。外镜筒211的截面形状也不限于图1中所示的圆形,也可为椭圆或菱形或异形。为了更好适配人体的形态特征,在靠近人体鼻梁附近,可以设置为与人体鼻梁匹配的形状,即将一个简单的圆形切除部分形成具有一与鼻梁匹配的倾斜面。因此,为了适应具体虚拟现实设备外壳,以及减小整体的虚拟现实设备的体积,外镜筒211的截面形可根据具体的虚拟现实外壳而定。
(2)外光学镜片212:外光学镜片212固定在外镜筒211上,具体的,如图2所示,外光学镜片212固定在外镜筒211的内侧顶部,内侧顶部即为远离内镜筒214的一侧。外光学镜片212与外镜筒211的固定方式具体可以是:通过塑胶将外光学镜片212固定在外镜筒211的内侧顶部,通过塑胶固定可以保证外光学镜片212稳定的固定在外镜筒211上,并且能有效防尘。需要说明的是,本发明不具体限定两者的固定方式。为了便于说明,将外镜筒211和外光学镜片212的组合结构定义为第一组件。
(3)内镜筒214:内镜筒214内置于外镜筒211,且内镜筒214可沿靠近或远离外光学镜片212的方向移动,进而外光学镜片212和内光学镜片217两者的间距可调。具体实现内镜筒214可沿外镜筒211移动的方式为:内镜筒214的侧壁上设有至少一个定位特征件,定位特征件与倾斜槽213一一对应,每一定位特征件嵌入倾斜槽213内并可沿倾斜槽213滑动,进而带动内镜筒214的移动。由于本发明未限定倾斜槽213的数量,则定位特征件的数量也不做具体限定。当倾斜槽213的数量为三个且沿外镜筒211周向均布时,三个定位特征件同时在倾斜槽213内移动,进而可保证内镜筒214上的内光学镜片217在上下移动过程中使其均处于一个平面上。进一步,由于外镜筒211与内镜筒214接触,为了提高调 焦过程中内镜筒214的滑动,在内镜筒214与外镜筒211之间增加了起到润滑作用的油层,提高内镜筒214的滑动灵活性,并且油层一定程度上能够阻止外界的灰尘进入内部,起到防尘作用。具体的油层可以通过在内镜筒214与外镜筒211之间涂阻尼油形成,应该理解为其他可以提高内镜筒214与外镜筒211之间的滑动灵活性的方式都为本申请的保护范围。当定位特征件为三个时,三个定位特征件的结构可以分为:两个固定螺钉220和拨动固定螺钉221,两个固定螺钉220和拨动固定螺钉221通过固定螺孔固定在内镜筒214上,且两个固定螺钉220和拨动固定螺钉221分别伸入倾斜槽213并可沿倾斜槽213滑动。为了能提高推动拨动固定螺钉221的舒适度,便于用户在使用过程便于拨动,该拨动固定螺钉221外侧端固定连接有拨动硅胶头222,该拨动硅胶头222为具有一定硬度的硅胶,用户使用起来手感比较舒适。如图10所示,内镜筒214包括圆台215和位于圆台215上方并向上延伸的至少一个凸台216,凸台216与倾斜槽213一一对应,固定螺孔位于凸台216上。凸台216的形状与外镜筒211内壁形状相吻合,当外镜筒211为圆形时,凸台216可以为环形壁,该凸台216上均设有与倾斜槽213相对应的固定螺孔。
(4)内光学镜片217:内光学镜片217固定在内镜筒214上。如图2所示,内光学镜片217固定在内镜筒214的内侧底部,如内镜筒214的底端设有卡槽,内光学镜片217与内镜筒214底端卡槽固定连接,内侧底部为远离外镜筒211的一侧。内光学镜片217与内镜筒214的固定方式具体可以是:通过塑胶将内光学镜片217固定在内镜筒214的内侧底部,通过塑胶固定可以保证内光学镜片217稳定的固定在内镜筒214上,并且能有效防尘。需要说明的是,本发明不具体限定两者的固定方式。当然内镜筒214也可以不设卡槽,可以将内光学镜片217固定在内镜筒214的内侧底部的侧壁,即内光学镜片217的外侧边与内镜筒214的内侧壁固定连接,固定方式可以通过塑胶固定可以保证内光学镜片217稳定的固定在内镜筒214上,并且能有效防尘。需要说明的是,本发明不具体限定两者的固定方式。为了便于说明,将内镜筒214和内光学镜片217的组合结构定义为第一组件。
(5)第一防尘件218和第一防尘件219:当内镜筒214通过伸入倾斜槽213的两个固定螺钉和拨动固定螺钉沿靠近或远离外光学镜片212的方向移动时,两个第一防尘件218分别一一固定在两个固定螺钉220对应的外圆筒2112的倾斜槽213外侧,第一防尘件219固定在拨动固定螺钉221对应的外镜筒211的倾斜槽213内侧。需要说明的是,第一防尘件219也可以固定在外侧。第一防尘件219和第一防尘件218上设有与倾斜槽213对应的槽口。第一防尘件219具体可为具有粘贴性的TPU片,该TPU片上有与特定倾斜槽213对应的倾斜槽213孔。本发明不限定第一防尘件219的材质为TPU,应该理解为,所选材质只要满足具有一定硬度便于进行开槽口,且具体防尘性质即可,如具有一定硬度的PORON或 一定硬度的PVC、高温胶或美纹胶等。第一防尘件218和第一防尘件219的固定方式均可通过粘贴的方式进行固定,便于组装,但本发明不限定其固定方式。上述光学镜片调焦组件的装配步骤为:
步骤一:将外光学镜片212固定在外镜筒211的内侧顶部,形成第一组件;
步骤二:将内光学镜片217固定在内镜筒214的内侧底部,形成第二组件;
步骤三:将第一防尘件219放入第一组件的外镜筒211的特定倾斜槽213的内侧,该特定倾斜槽213用于伸入拨动固定螺钉。
步骤四:将第二组件置于第一组件内侧,即将组装好的带有内光学镜片217的内镜筒214置于组装好的带有外光学镜片212和第一防尘件219的外镜筒211的内侧。
步骤五:由于内镜筒214的侧壁上设有三个固定螺孔,三个固定螺孔外漏于倾斜槽213,然后在三个固定螺孔上分别固定连接两个固定螺钉220和一个拨动固定螺钉221。两个固定螺钉220伸入的倾斜槽213对应的外镜筒211的侧壁上分别固定连接两个第一防尘件218。
步骤五:将拨动硅胶头222固定在拨动固定螺钉221外侧端。
需要说明的是,上述的具体装配步骤不构成先后限制,可以根据具体情况安排其步骤的先后顺序。光学镜片调焦组件主要应用于虚拟现实领域,特别是短距离的光学镜片调节,应该理解为其他领域进行短距离的光学调焦也在保护范围内。
上述光学镜片调焦组件的工作原理具体为:拨动拨动硅胶头222使其带动拨动固定螺钉221在外镜筒211的倾斜槽213上进行上升或下降的倾斜滑动,由于拨动固定螺钉221一端固定在内镜筒214上,并且与其他两个固定螺钉220使内镜筒214在一个相对平面内。在拨动固定螺钉221沿倾斜槽213滑动的过程中,内镜筒214上的内光学镜片217与外镜筒211的外光学镜片2122的间距可调,具体的变化需要根据倾斜槽213的倾斜幅度以及倾斜槽213的槽口长度决定,优选的在倾斜角度在5-15度,内光学镜片217和外光学镜片212的距离调节范围在0.5-10mm之间。
(三)脸托6:如图14和15所示,脸托6包括主体固定部64和面部接触部63,面部接触部63一侧与主体固定部64连接,另一侧与人体面部相接触,主体固定部64还与虚拟现实设备的后壳3连接,不具体限定连接方式。主体固定部64和面部接触部63均可为一体成型结构。下面分别针对主体固定部64和面部接触部63进行说明。
(1)主体固定部64:为了便于脸托配件的使用,主体固定部64的形状可为由两端向中心拱起的几字形结构,具体可为凸缘和位于凸缘两侧的弧形部组成的几字形,可实现将虚拟现实设备的重力分散到人体面部多处位置。主体固定部64上设有至少一个凸出于其外表面的凸起,不局限附图中所示的凸起的数量为四个,其中两个为位于凸缘上的凸起61,另两个为位于弧形部上的凸起62。与该凸起相对应的是,如图3(b)所示,虚拟现实设备的后壳3上设有用于嵌入凸起的脸托固定件41和43,脸托固定件41和43具体可以为开口,实现了主体固定部64与虚拟现实设备的连接。当主体固定部上设有四个固定件时,其中两个凸起61位于凸缘靠近中轴线的两侧,在使用时,两个凸起位于用户鼻梁附近对应的位置;另外两个凸起62位于弧形部上,对应于靠近脸部颧骨附近。为了节约材料,以及使脸托形状比较美观,优选的主体固定部64与配套使用的虚拟现实设备的待固定位置相对应。为了便于生产,主体固定部64为一体成型,且优选质轻材料。
(2)面部接触部63:面部接触部63一侧与主体固定部64连接,另一侧与人体面部相接触。为了分散虚拟现实设备的重力,面部接触部63的形状同样可设为由两端向中心拱起的几字形结构,具体可为凸缘和位于凸缘两侧的弧形部组成的几字形,弧形部沿远离凸缘的方向延伸。在脸托6实际使用过程中,凸缘可对应到使用者鼻梁附近,弧形部可沿眼尾方向延伸,更好的让脸托配件承受到力分配的人体面部,即让面部接触部与人体面部接触的地方受力均匀。沿凸缘至远离凸缘的方向,面部接触部63的厚度为先逐步变厚,后逐步变薄,且中心的厚度小于两端端部的厚度,即面部接触部63中心轴附近厚度较薄,自由端厚度较厚。在面部接触部63与人体面部相接触的一面为具有一定角度的倾斜面,即将该面设置为与人体面以及鼻梁面相匹配的面。该倾斜面可具体包括鼻部倾斜面和脸颊倾斜面,鼻部倾斜面的面积小于脸颊倾斜面的面积,其中,鼻部倾斜面与竖直面的角度为10°~80°,脸颊倾斜面与竖直面的角度为3°至60°。此外,鼻部倾斜面对应的面部接触部厚度可小于脸颊倾斜面对应的面部接触部厚度。考虑到面部接触部63需要与人体进行接触,面部接触部63优选质轻且柔软材质,比如泡棉。同时为了便于生产加工,面部接触部63可为一体成型。如图15所示,上述脸托6安装到后壳3上的具体安装步骤如下:
第一步:将主体固定部64和面部接触部63固定连接,形成脸托6。固定连接方式不具体限定,如可采用粘贴方式进行固定连接;
第二步:将主体固定部64固定到虚拟现实设备的后壳3上。不具体限定固定连接方式,如主体固定部64上若有若干凸出于其外表面的凸起61和62,虚拟现实设备的后壳3上与凸起61和62相对应的脸托固定件41和43,脸托固定件41和43具体可以为开口,通过凸起卡入开口中实现主体固定部64和后壳3的固 定。
值得注意的是,脸托6整体的横向长度为60~160mm,优选的90~30mm,特别是100~20mm这样可以满足大部分人体的脸部,比如横向长度设为110mm±8mm;脸托配件整体的纵向高度20~80mm,优选的30~70mm,特别是45~55mm这样可以满足大部分人体的鼻部,比如纵向设为48mm±5mm。应该理解为,本申请的脸托配件充分利用人的脸部形态特点,让用户配戴虚拟现实设备时,尽可能的增大与用户面部的接触面,将虚拟现实设备的重力进行分散。
本申请的脸托区别于现有脸托只与鼻梁部分进行接触,增大与用户面部的接触面,即脸托配件不仅与鼻梁接触,而且还与眼部附近位置接触,进而将虚拟现实设备的重力进行分散,鼻梁和鼻梁两侧的眼周都可承受虚拟现实设备的部分重力,减少用户使用虚拟现实设备配戴带来的不舒服以及损伤,可以让用户长时间舒服的使用头戴设备,大大的提高用户的体验度。
(四)遮光组件7:如图16至图18所示,遮光组件7包括:遮光件78和前端固定环77;遮光件78包括顶面73、第一曲面75、第二曲面76和底面74,其中:顶面73与人体面部相接触的一侧为由中心向外延伸的非封闭弧形;底面74整体与顶面73整体上下相对设置;第一曲面75和第二曲面76位于顶面73两侧,并均向靠近底面74的方向弯曲;第一曲面75和第二曲面76均分别与顶面73和底面74光滑过渡连接,使得顶面73、第一曲面75、第二曲面76和底面74围成一封闭中空区域;前端固定环77位于中空区域的最外侧的内周边并与其吻合。同时,由于本发明虚拟现实设备的遮光组件与虚拟现实设备主体配套使用,为了便于该遮光组件7的固定,第一曲面75和第二曲面76上各分别设有连接件71和72,为了便于区分,分别用第一连接件71和第二连接件72表示,第一连接件71和第二连接件72用于固定在虚拟现实设备的左镜腿5和右镜腿4上。如爆炸图图16所示,遮光组件7为一罩体结构,包括一个前端固定环77、一个遮光件78、一个第一连接件71和一个第二连接件72,下面分别针对上述各部件进行详细说明。
(1)前端固定环77:前端固定环77内置于遮光件78最外侧,当将遮光组件7应用到虚拟现实设备主体时,前端固定环77位于中空区域的内周边并与虚拟现实设备主体前端接触,如当虚拟现实设备为眼镜形态时,前端固定环77可以包围镜框部分,此处镜框部分排除镜腿。前端固定环77可为一个镂空密闭框架,由于前端固定环77需要包围虚拟现实设备主体,所以前端固定环77的形状需与虚拟现实设备主体本身外侧形状相对应。可以理解的是,如虚拟现实设备主体的形状可以为长方形,正方形以及各个不同规则的形状,则前端固定环77的形状需要相应变化。例如,当虚拟现实设备主体选择具有一定弧度且与眼镜形态相对应的形态时,前端固定环77的形状也优选为眼镜形态,即前端固定环77的 形状是根据虚拟现实设备主体外侧边缘的形状而定。需要说明的是,前端固定环77可以是镂空,当然也可以是实心结构,为了节约材料、减轻用户配戴重量,提高用户体验度,前端固定环77优选为镂空。
(2)遮光件78:遮光件78包括顶面73、第一曲面75、第二曲面76和底面74。当将遮光组件应用到虚拟现实设备主体时,前端固定环77用于包括虚拟现实设备主体前端外框架,第一曲面75和第二曲面76可沿镜腿方向延伸,第一曲面75和第二曲面76上的第一连接件71和第二连接72固定在左镜腿5和右镜腿4上,实现遮光组件7固定在虚拟现实设备主体上,用户在使用配置有遮光组件的虚拟现实设备时,遮光件78围成的中空区域与人体面部能形成相对密闭的空间,避免外界的光学进入。遮光件78通过前端固定环77和虚拟现实设备主体连接,遮光件78的第一曲面75和第二曲面76沿靠近虚拟现实设备末端的方向延伸,顶面73与人体面部相接触的一侧为由中心向外延伸的非封闭弧形,该非封闭弧形可以与人体额头相匹配,底面设为由两端向中心拱起的W形,也同样与人体脸型相匹配,这样做不仅仅可以节约材料,还可以减轻遮光组件的重量,并且能够提高用户的配戴舒适度并且达到良好的遮光效果。具体的,遮光件78可选择具有一定硬度、可透气且能够防止光线透过的软性材质。优选的,为了便于遮光组件在使用过程中美观,可以选择具有一定弹性并且不容易褶皱的材质,例如拉架棉、莱卡等。例如,材质选择一种合成布,该合成布具有两层,一侧用来进行遮光,另外一层用来进行保证透气并且不易变形。由于一般的布料都比较柔软,难以成型,为了解决该问题,提高合成布的弹性、硬度并且耐磨性,通过胶水将两层布料进行合成。遮光件78具有容纳虚拟现实设备主体前端的中空区域,具体的,中空区域包括面部接触面和虚拟设备连接面;面部接触面用于与用户面部接触,虚拟设备连接面用于与虚拟现实设备的框体内侧的观看侧连接;或中空区域包括面部接触面和虚拟设备连接面;面部接触面用于与用户面部接触,虚拟设备连接面用于与虚拟现实设备的框体外侧连接。由于本实施例中的虚拟现实设备的光学组件可以为调焦组件,光学组件具体包括外镜筒211、固定在外镜筒211的外光学镜片212、内镜筒214、固定在内镜筒214的内光学镜片217和定位特征件(具体为的固定螺钉220和拨动固定螺钉221);外镜筒211侧壁上设有至少一个倾斜槽213;内镜筒214内置于外镜筒211;定位特征件(具体为的固定螺钉220和拨动固定螺钉221)与倾斜槽213一一对应,各定位特征件(具体为的固定螺钉220和拨动固定螺钉221)一端固定在内镜筒214的侧壁,另一端穿过倾斜槽213可在倾斜槽213内滑动。定位特征件(具体为的固定螺钉220和拨动固定螺钉221)即为虚拟现实设备凸出控制键,当调节定位特征件(具体为的固定螺钉220和拨动固定螺钉221)使内镜筒214沿外镜筒211相对滑动时,固定在外镜筒211上的外光学镜片212与固定在内镜筒214上的内光学镜片217之间的距离可调,实现了光学组件的调焦。为了使得上述凸出控制键便于操作,遮光 件78的底面上设有开孔,开孔用于虚拟现实设备凸出控制键即定位特征件外露,在实现调焦的同时也实现了遮光。上述虚拟现实设备的遮光组件7的尺寸可以为:为了适配人体头部形态的大小,遮光组件7的前端横向距离相对小于后端纵向距离。一般遮光组件的前端横向长度为50~250mm范围内任意值,优选为120~170mm范围内任意值,特别是150~160mm之间最适合大众用户尺寸,具体比如155mm。纵向长度在30~150mm范围内任意值,优选为60-120mm范围内任意值,特别是80~100mm之间最适合大众用户尺寸,具体如91mm。遮光组件顶面的弧形的最底端至遮光罩前端的距离为3~25mm范围内任意值,优选为8-20mm范围内任意值,特别是12~16mm之间最适合大众用户尺寸,具体如14mm。
上述虚拟现实设备的遮光组件7的工作原理为:用户在使用带有遮光组件的虚拟现实设备时,用户带上虚拟现实设备,遮光组件7的遮光件78就会与用户的额头以及用户的脸以及虚拟现实设备一起形成一个相对密闭的空间,可以让用户眼睛避免外界的光线干扰,只看到虚拟现实设备提供的视觉光线,让用户能够很好的沉浸到虚拟现实设备的视频场景中,大大的提高用户的体验度。上述虚拟现实设备的遮光组件7的具体安装步骤如下:
第一步:通过遮光组件的封闭中空区域将虚拟现实设备主体包围,位于封闭中空区域内周边的前端固定环77与虚拟现实设备的前端框架相接触;
第二步:通过第一连接件71和第二连接件72将遮光组件的第一曲面75和第二曲面76固定在虚拟现实设备上,第一曲面75和第二曲面76沿虚拟现实设备末端的方向延伸。当虚拟现实设备为眼镜结构时,第一连接件71和第二连接件72分别与虚拟现实设备的镜腿固定,具体可以为虚拟现实设备(虚拟现实眼镜)的两个镜腿上各分别设有用于嵌入第一连接件71和第二连接件72的通孔51,当第一连接件71和第二连接件72嵌入通孔51时,可实现遮光件78和虚拟现实设备主体的固定,并且也便于拆卸下来,便于用户操作,提高用户的体验度。可以理解的是,虚拟现实设备和遮光件78也可通过粘贴的方式实现固定,对本发明不具体限定固定方式。
(五)PCBA板8:如图7所示,后壳3包括收纳腔46,用来收纳虚拟现实设备的PCBA板8,PCBA板8与光学系统连接,具体的,PCBA板8与左显示屏22、右显示屏24的屏面垂直连接。同时,光感组件还连接PCBA板8,且与PCBA板8平面保持垂直。
(六)散热片9:散热片9分别与左显示屏22和右显示屏24的后方贴合,并与PCBA板8的发热器件贴合。具体的,散热片9包括铜箔层和位于铜箔层的外层的碳膜层,铜箔层与左显示屏22和右显示屏24的后方贴合,并与PCBA板8的发热器件贴合。具体的,由于显示屏发热小,因此可在左显示屏22和右显示 屏24的后方选取一部分表层涂导热胶并与散热片9连接。由于显示屏与散热片仅部分粘贴连接,便于后期维护过程中的拆卸。由于PCBA板的芯片发热比较大,要让其热量充分散发出去,因此可将PCBA板的发热器件表层涂满导热胶并与散热片9连接。考虑到光感组件也会被散热片9遮挡住,为了便于维修,在光感组件或其他散热片遮挡的器件对应的散热片处可以设置维修开口,便于后期进行维修,而避免了维修过程中需要将整个散热片拆卸下来进行维修。
(七)数据线固定件19:如图19至21所示,数据线固定件19用于固定在虚拟现实设备上。具体的,虚拟现实设备包括镜框和镜腿,镜框的后壳3靠近镜腿的一侧设有镜脚连接部,该镜脚连接部上设有凹槽44,镜腿上设有可嵌入凹槽44的凸起53。经过上述说明,为了虚拟现实设备的整体美观,数据线固定件19固定在镜脚连接部上,如螺钉连接。
数据线固定件19包括顶面和分别与顶面连接并相对设置的第一侧面和第二侧面,其上分别形成有用于固定在虚拟现实设备上的固定部191、镂空开口192、数据线收容腔193和数据线挡板194,下面针对上述各部件进行详细说明。本实施例中,设定第二侧面与虚拟现实设备的镜脚连接部固定连接,第一侧面位于虚拟现实设备的外周边的内侧,第一侧面、第二侧面和顶面围成的数据线收容腔与虚拟现实设备的接口相对应,则固定部191位于第二侧面上并沿远离顶面的方向延伸,固定部191用来将数据线固定件19固定在虚拟现实设备上。固定部191与虚拟现实设备可拆卸连接,如虚拟现实设备上设有螺钉孔,固定部191与虚拟现实设备通过螺钉195连接;或固定部191与虚拟现实设备不可拆卸连接,如焊接等,具体不做限定。
为了减轻数据线固定件19的重量以及节约材料,第一侧面和/或第二侧面上设有镂空开口,不局限于图1中所示的第二侧面上设有镂空开口192。顶面、第一侧面和第二侧面围成一三面开口的U形的数据线收容腔193,与虚拟现实设备连接的数据线的连接头收容在数据线收容腔193内。为了进一步防止数据线的连接头松动或掉落,避免数据线松动到时连接不良的问题,数据线固定件19上还可以进一步设有数据线挡板194,数据线挡板194设在数据线固定件19远离虚拟现实设备的一侧,数据线挡板194可分别与顶面和第一侧面连接,并与第二侧面之间具有用于伸入数据线的间隔;或数据线挡板194可以与第二侧面和顶面连接,并与第一侧面之间具有空隙,该空隙用于伸入数据线,同时数据线的连接头容纳在数据线收容腔193内,该数据线挡25板用于防止连接头脱离数据线收容腔193。将数据线固定件19安装到虚拟现实设备的具体步骤如下:
第一步:在虚拟现实设备上连接好数据线,即将数据线的连接头插入到虚拟现实设备上的数据线接口,本实施例中的数据线一般为HDMI数据线,当然也可采用其他用来进行数据传输或者进行充电的数据线,不做具体限定;
第二步:将数据线固定件19固定在虚拟现实设备上,数据线的连接头位于数据线固定件19中数据线收容腔193内。需要说明的是,本发明的数据线固定件19可为一体成型,优选的材质为轻质并且具有一定硬度的材质。
上述数据线固定件19的工作原理为:首先将数据线的连接头固定在虚拟现实设备的数据线接口上,然后数据线的连接头也容纳在数据线固定件19的数据线收容腔193内,同时数据线固定件远离虚拟现实设备的数据线接口的一侧还设有数据线挡板194,数据线挡板194用于防止数据线的连接头松动或掉落,阻挡数据线的连接头向外移动,使得数据线与虚拟现实设备良好连接,避免用户在使用过程中外接的数据线松动,导致数据传输不良甚至数据线脱落的问题,可以让用户大胆的进入的虚拟现实的场景互动中,提高用户体验度。
与现有技术相比,本发明中的虚拟现实设备新增加了数据线固定件19,在收纳数据线的连接头的同时将数据线固定在虚拟现实设备上,能有让数据线连接头在可控发范围移动,甚至不发生移动,这样就可以让数据线很好与虚拟现实设备进行连接,即便用户使用过程中进行剧烈的运动也不会导致数据线脱落,较大的提高了用户的体验度,并且提高了虚拟现实设备的适用场景。

进一步地,参见图14和图15,本申请提供的脸托,作为虚拟现实设备的一种配件,包括固定在一起的面部接触部63和主体固定部64。实际佩戴过程中,面部接触部63通过主体固定部64安装在虚拟现实设备的后壳3中部位置。为了增加佩戴时的舒适感,面部接触部63使用较柔软的材料制成,例如海绵、泡棉等;而为了便于将脸托6安装在虚拟现实设备上以及增加安装后脸托的稳定性,主体固定部64可以采用具有一定弹性和硬度的材料制成,如塑料,轻质金属等。面部接触部63与主体固定部64之间的固定方式应满足稳定性需求,例如胶合、不产生相互滑动的可拆卸连接等方式。
如图14和图24所示,本申请提供的脸托配件中,面部接触部63和主体固定部64是由位于中心线601的凸缘602和相对中心线601对称的两个弧形部603组成的几字形结构。其中,面部接触部63包括侧部接触段604,以及从凸缘602延伸至侧部接触段604的中部接触段605。应当说明的是,中心线601位于凸缘602的中部位置,将整个面部接触部63和主体固定部64界定为相对于中心线601对称的两个部分,其中,每个部分都包括弧形部603。弧形部603再沿着远离凸 缘602的方向进一步划分为中部接触段605和侧部接触段604,显然,中心线601、凸缘602、中部接触段605以及侧部接触段604都是表示方位特征的名称,指代面部接触部63和主体固定部64的位置。在面部接触部63和主体固定部64都可以通过上述特征表示实体中对应的位置。
面部接触部63包括内缘631和外缘632,以及从内缘631延伸到外缘632的贴合侧633和连接侧634。对于面部接触部63的内缘631,是指面部接触部63在佩戴过程中,与佩戴者面部接触的几字形结构的内部边缘位置;而对于面部接触部63的外缘632是指在虚拟现实设备中,与光学模组配合的几字形结构的外部边缘位置。通过以上两个边缘位置的设定,可以将整个面部接触部63划分为与佩戴者面部相接触的贴合侧633,以及与主体固定部64接触的连接侧634。
参见图26,贴合侧633上厚度L最大值的点构成一条连续的贴合曲线635。整个贴合曲线635随着面部接触部63的形状变化而变化。贴合曲线635在整个面部接触部63上形成凸起的结构,并在贴合曲线635的两侧分别形成贴合面636和外缘支撑面637。对于贴合面636,是在贴合曲线635靠近内缘631的一侧连续延伸的平滑曲面,贴合面636的曲面变化规律应与人体的面部结构相符,使得在位于两个中部接触段605的贴合面636与佩戴者的鼻部侧面贴合;在位于两个侧部接触段604的贴合面636与佩戴者面部贴合。这样的结构不仅可以增加佩戴时与用户面部的接触面,减小单位面积的压力,便于用户长时间配戴;而且能让不同鼻形和脸型的用户都能很好的得到适配。
外缘支撑面637是位于贴合曲线635靠近外缘632侧的曲面,外缘支撑面637与虚拟现实设备的光学模组贴合。为了便于调整成像距离,对于不同视力情况的佩戴者,虚拟现实设备往往通过在屏幕与人眼之间设置光学模组。一般光学模组包括镜筒和设置在镜筒内部的透镜,由于需要留有调整距离,光学模组会凸出虚拟现实设备的后壳3。在本申请提供的技术方案中,外缘支撑面637与光学模组凸出后壳3部分的镜筒外壁贴合,既不影响光学模组的调整,又避免外缘支撑面637与后壳3之间形成缝隙造成漏光,影响观影效果。
而对于与贴合侧633相反的连接侧634,如图25所示,连接侧634上设有连接槽638,连接槽638的槽底面6381靠近内缘631位置设有连接面6382;外缘支撑面637与槽底面6381连接。槽底面6381在安装位置时,与虚拟现实设备的后壳3平行,即在佩戴过程中,槽底面6381与显示屏幕、前壳2和后壳3保持平行。也就是当虚拟现实设备处于零位时,槽底面6381处于竖直状态。槽底面6381沿着贴合曲线635从凸缘602延伸到两个侧部接触段604。
连接面6382是相对于槽底面6381倾斜设置的曲面,连接面6382根据整个面部接触部63的外形变化而连续变化。连接面6382在连接侧634上形成相对于 槽底面6381的凸出曲面,而在贴合侧633,贴合面636是相对于贴合曲线635向连接侧634凹下的曲面,这样的结构可以减小贴合面636与连接面6382之间的距离,进而减轻整个面部接触部63的重量,也使得虚拟现实设备整体更加轻薄。也便于在承受力的时候力的均匀传递,减弱其的损坏,增强其的使用寿命。
如图27所示,贴合面636和连接面6382均相对于槽底面6381倾斜设置,但对于贴合面636,其倾斜规律是以贴合曲线635为起点,向连接侧634的方向上倾斜,形成相对于贴合曲线635逐渐降低的曲面,直到内缘631;而对于连接面6382,其倾斜规律是以槽底面6381为起点,向连接侧634的方向上倾斜,形成相对于槽底面6381逐渐升高的曲面,直到内缘631的位置。
对于贴合面636与槽底面6381之间的内倾角α,本实施例中,如图26所示,内倾角α被定义为,在贴合面上,垂直于贴合曲线635上任意一点的切线方向,向内缘631方向划定的直线,与槽底面6381之间的夹角。在从凸缘602过渡到中部接触段605再过渡到侧部接触段的过程中,内倾角α先逐渐增大后逐渐减小。
同理,对于连接面6382与槽底面6381之间的外倾角β,被定义为,在连接面6382上,垂直于内缘631任意一点的切线方向,向槽底面6381的边缘划定的直线,与槽底面6381之间的夹角,其变化规律与内倾角α的变化规律相同。在本申请的部分实施例中,沿垂直于贴合曲线635的切线,垂直槽底面6381方向所做的任意切面中,内倾角α等于外倾角β,即贴合面636和连接面6382与切面的之间形成的两条交线相互平行。从而形成质量均匀的面部接触部63,使贴合面636上各点承受的压力相对均匀一致,避免用户配戴时间长不舒服,和造成接触部损伤;增大接触面,还可以保证面部接触部63稳定的固定在佩戴者的面部。
在面部接触部63的凸缘602上,内倾角α和外倾角β均连续变化,在凸缘602的中心线601位置上,内倾角α和外倾角β最小,在远离中心线601向中部接触段605的方向上,内倾角α和外倾角β逐渐增大。这一结构可以适应佩戴者在两眼之间的鼻梁结构,由于面部接触部63的凸缘602需要跨越佩戴者的鼻梁顶部位置,而鼻梁顶部位置相对于面部突出的较少,因此在中心线601位置的内倾角α和外倾角β最小,以此来适应用户的面部结构,使虚拟现实设备的显示画面正好位于用户眼镜的正前方。
在面部接触部63的中部接触段605上,内倾角α和外倾角β先逐渐增大后逐渐减小。本实施例中,面部接触部63的中部接触段605用于与佩戴者的两个鼻梁侧面相贴合。对于大部分佩戴者而言,鼻梁的宽度从上向下依次变大,并且鼻梁也依次变高,因此在远离凸缘602的方向上,内倾角α和外倾角β先逐渐增大,但虚拟现实设备的脸托不仅与鼻梁接触,在过渡到靠近面颊位置后,内倾角α和外倾角β开始逐渐趋于平缓,以适应佩戴者的面部结构。
在面部接触部63的侧部接触段604上,内倾角α和外倾角β在远离中部接触段605的方向上逐渐变小。对于侧部接触段604,是逐渐远离鼻梁接触的位置,沿佩戴者的鼻梁两侧逐渐过渡到佩戴者的颧骨位置。对于大部分用户而言,从鼻梁侧部到颧骨位置,面部的倾斜角度逐渐变大,而相应与面部贴合的脸托贴合面636的倾斜角度则逐渐变小,才能使得贴合面636与面部均匀贴合。
连接侧634在内缘631的位置还设有连接贴合面636和连接面6382的内缘支撑面639。在本申请提供的脸托中,内缘支撑面639用于在贴合面636和连接面6382之间形成平滑连接的过渡面,内缘支撑面639在佩戴过程中,不与佩戴者的面部相接触。但作为贴合面636和连接面6382之间的过渡面,其作用依旧不可或缺。由于不同佩戴者之间的面部结构存在差异,在不同的佩戴者之间切换使用时,会因为面部结构的不同,而使得软质材料制成的面部接触部63,产生不同的形变量。在贴合面636与连接面6382设置有内缘支撑面639,就可以将产生的形变进行缓冲,避免由于变形,使虚拟现实设备偏离预定显示位置,影响观影体验。另外,内缘支撑面639在侧部接触段604的末端606位置与外缘支撑面637连接,使整个面部接触部63成为一个顺滑连接的整体。
本申请提供的脸托配件中,还包括用于将面部接触部63固定在虚拟现实设备后壳3上的主体固定部64。为了配合面部接触部63,主体固定部64上应具有与槽底面6381和连接面6382形状相符的结构。这样可以让主体固定部64与面部接触部63充分的接触,增加连接固定的牢固性,并且增强力度传递的均匀性。在实际使用中,通过胶合或可拆卸的固定方式,将面部接触部63和主体固定部64固定在一起,再通过主体固定部64将面部接触部63安装在虚拟现实设备上。
由以上实施例可知,本申请提供的脸托,由连续的贴合曲线635划分而成的贴合面636和外缘支撑面637,分别与佩戴者面部以及虚拟现实设备的镜头模组配合,贴合面636与槽底面6381形成的内倾角α在整个面部接触部63上连续变化,使面部接触部63与佩戴者的面部配合。在凸缘602过渡到中部接触段605再到侧部接触段604的过程中,内倾角α先逐渐增大后逐渐变小,满足面部轮廓特征,使得脸托的贴合面636与鼻侧和面颊充分贴合。
因此,以上实施例中提供的脸托,可以使面部承受虚拟现实设备的压力基本趋于一致,增加了与用户鼻部和脸部接触的面积,给用户带来舒适的佩戴感觉,并使脸托连通虚拟现实设备在佩戴时更加稳定。此外,贴合面636与面部的充分贴合还能减少贴合部位的漏光现象的发生,提高观影效果的同时还能够避免使用面积较大的遮光罩,有助于减轻虚拟现实设备的整体重量,使虚拟现实设备在佩戴时不易受重力影响而脱离面部位置。
参见图26,在本申请的部分实施例中,侧部接触段604沿贴合曲线635,在 远离中部接触段605方向上的厚度L先逐渐增大后逐渐减小。在上述实施例中,由于内倾角α在侧部接触段604上,在远离中部接触段605的方向上逐渐变小,可以形成用于贴合佩戴者面颊部位的贴合面636。但由于大多数人的颧骨凸起,使得面颊两侧的高度略高于靠近鼻梁的位置。如果仅通过内倾角α的角度变化,来适应佩戴者的面部结构,会使得在靠近鼻梁位置的面颊处的接触面积过小,增加重量的同时,也会减少整个结构在佩戴时的稳定性。
因此,本实施例中,通过改变厚度L,使整个面部接触部63在靠近鼻梁两侧的厚度L最大,两侧的厚度L逐渐变小,使得贴合面636与面部轮廓贴合的面积尽可能达到最大。同时减少整个脸托的体积,进而降低脸托的重量,以此来保证脸托及虚拟现实设备整体具有较高的稳定性。
进一步地,在侧部接触段604厚度L的最大值对应点,在侧部接触段604上贴合曲线635的45%~55%位置处,应当说明的是,这里所指的贴合曲线635中的比例关系是以位于侧部接触段604部分的贴合曲线635为区域,并非指代整条贴合曲线635。并且在上述比例是以凸缘602为起点,向侧部接触段604的方向上进行计算的。因此,在本实施例中,厚度L的最大值对应在贴合曲线635的45%~55%的区域是指在侧部接触段604部分,厚度L的最大值点出现在沿贴合曲线635中部附近的位置。当用户配戴虚拟现实设备时,该部分刚好与人体面部位置对应,这样可以便于与用户面部接触,让力传递到面部,让用户长时间配戴也不容易感觉到过重,并且也有助于保持虚拟现实设备稳定固定在头部,避免长时间配戴由于肌肉受力变形导致头戴设配戴发生变化。
本申请对于侧部接触段604是指脱离鼻梁两侧的接触位置开始,到末端606之间形成的区域,对于侧部接触段604中,贴合曲线635的50%位置处即对应于佩戴者面部的鼻梁与颧骨之间形成的凹陷区域。而对于不同人体的面部参数,存在±5%的偏差范围。例如,对于亚洲人种,两侧颧骨之间的距离较近,应使得厚度L的最大值对应的点设置在贴合曲线635的55%位置,而对于颧骨之间距离较远的欧洲人种,则需要适当调整厚度L最大值对应的点,使其位于贴合曲线635的45%位置。
另外,本实施例中,侧部接触段604在满足厚度L的最大值位于贴合曲线635的45%~55%后,还要满足厚度L的最小值为最大值的50%~60%。对于不同用户类型的虚拟现实设备,其大小存在着较大的差别,例如,对于儿童和成年人使用的虚拟现实设备,存在着型号上的差异,对应的厚度L也存在着较大的不同,但由于面部轮廓的比例基本固定,因此,本实施例中,侧部接触段604上的厚度L的最小值限定为最大值的50%~60%,以适应多数人的面部轮廓。
同样,由于不同人种之间存在的面部结构差异,以及由于胖瘦的影响,同一 人种之中也存在着一定的面部差异,例如,对于颧骨较高的欧洲人种,应该使厚度L的最小值是最大值的50%,以适应面部凸起高度,而对于面部较平的亚洲人种,则应使厚度L的最小值维持在最大值的60%。除此之外,对于佩戴者而言,一般身材瘦小的佩戴者,面部凸起相对明显,而身材肥胖的佩戴者面部凸起相对较小,因此在不同型号的虚拟现实设备中,也应根据实际佩戴情况在上述范围内确定最适宜的比例关系。
应该理解的是申请的实施例中的比例,最大值,最小值以及具体的占比范围的数值都仅仅是针对大众化的一个范围,具体的值可以根据实际的情况进行改变,比如针对某些特殊人群的定制,只要不偏离本申请的本质通过让配戴虚拟现实设备时,尽可能的与人体鼻部以及面部接触,通过增加接触面积减少单位面积的承重,来避免用户长期配戴虚拟现实设备产生的不舒适感以及配戴稳定性问题。
在本申请的部分实施例中,中部接触段605沿贴合曲线635,在远离凸缘602方向上的厚度L逐渐增大,且在中部接触段605厚度L的最小值为最大值的50%~60%。对于中部接触段605,在实际佩戴过程中,是与佩戴者的鼻梁两侧贴合的区域。在此区域中,从鼻梁顶部向下,即在远离中线段602的方向上,鼻梁的高度逐渐变大的同时,鼻梁两侧相对于面部的倾斜角度逐渐变小。
同样,通过上述实施例中内倾角α在中部接触段的变化,虽然可以使中部接触段605的贴合面636与鼻梁两侧贴合,但是在从鼻梁顶部逐渐向下过渡的过程中,鼻梁的高度增加,会使脸托的贴合面积逐渐变小,对于部分鼻梁较高的佩戴者而言,甚至出现鼻梁两侧与贴合面636分离的情况。因此,为了避免上述情况的发生,本实施例中,中部接触段605沿贴合曲线635,在远离凸缘602方向上的厚度L逐渐增大,厚度L逐渐增大的规律应与多数人鼻梁高度的变化规律相符。
进一步地,在中部接触段605厚度L的最小值为最大值的50%~60%,对于鼻梁高度较小的佩戴者,应使中部接触段605处的厚度L最大值与最小值之间的比例关系较大,以避免贴合面636的增大而对整体重量的增加;而对于鼻梁较高的佩戴者,应减小厚度L最大值与最小值之间的比例关系,以增加贴合面636在鼻梁两侧的贴合面积,增加整体的稳定性。
在本申请的一种技术方案中,凸缘602沿贴合曲线635,在远离中部接触段605方向上的厚度L逐渐减小。由于凸缘602是相对于中心线601两侧对称的凸缘结构,因此在中心线601两侧的区域内,凸缘602在远离中部接触段605方向上的厚度L逐渐减小则意味着,在中心线601处的凸缘602的厚度L达到最小值。这样的结构可以使凸缘602贴合鼻梁的顶部位置,增加整体稳定性的同时,可以避免在鼻梁顶部位置上的漏光现象。
进一步地,凸缘602厚度L的最小值为最大值的10%~15%。由于在与鼻梁顶部接触的位置并不承受太多虚拟现实设备整体的重量,仅是在佩戴者的鼻梁顶部位置进行遮光处理,因此,此处最小值应当与最大值之间存在较大的差异,以适应鼻梁的整个顶部结构。另外,在鼻梁顶部的贴合位置上,凸缘602的整体厚度L应较中部接触段605和侧部接触段604的厚度L更薄,以减轻整体的重量。
根据上述实施例提供的面部接触部63,本申请提供的脸托配件中,还包括与面部接触部63形状相适配的主体固定部64,主体固定部64进一步包括:后壳侧641;以及与面部接触部63的连接侧634贴合的脸托侧642。为了能够与面部接触部63固定在一起,增加整体的稳定性,本实施例中,如图28、图29所示,脸托侧642设有与槽底面6381贴合,且形状与槽底面6381相同的限位面643,以及与连接面6382贴合的固定面644。
在实际使用中,由于面部接触部63由软质材料制成,而主体固定部64由硬质材料制成,因此在两者进行固定连接时,很有可能因为软质材料的变形而导致整个面部接触部63偏离预定的位置,从而影响脸托整体的稳定性。因此为了增加整体结构的稳定性,本实施例中,在主体固定部64的脸托侧642,分别设置了与槽底面6381形状相适应的限位面643,以及,与连接面6382形状相适应的固定面644,通过整体形状上的限制,将面部接触部63稳定的限制在主体固定部64上。
根据上述实施例中描述的主体固定部64,在本申请的部分实施例中,如图30所示,后壳侧641包括后壳贴合面6411以及连接后壳贴合面6411的过渡面6412。后壳贴合面641在实际固定过程中,与虚拟现实设备的后壳3贴合。具体的可以通过粘贴固定或者可拆卸固定等固定方式,可选的,选择可拆卸的固定,具体例如后壳贴合面6411和过渡面6412分别设有相对于中心线601对称的至少两个锁紧件60。
本实施例中,分设于后壳贴合面6411和过渡面6412上的锁紧件60,可以通过锁紧件60实现主体固定部64在虚拟现实设备上的可拆卸连接,从而使得同一个虚拟现实设备可以根据不同的佩戴者更换脸托配件,以适应不同的用户。具体使用过程中,后壳贴合面6411充分与虚拟现实设备贴合,以及连接后壳贴合面6411的过渡面6412跟虚拟现实设备的下部分的倾斜能够虚拟现实设备进可能的与之接触,这样用户在配戴虚拟现实设备时,虚拟现实设备与主体固定部能形成面部受力,让力的传递更均匀,以及也可以让主体固定部与虚拟现实设备更加固定更稳定。
进一步地,锁紧件60包括:设置在过渡面6412靠近中部接触段605位置的卡扣61;以及设置在后壳贴合面6411靠近侧部接触段604位置的锁紧销62。本 实施例中,设置在主体固定部64的中部接触段605上的卡扣61具有弹性,能够与后壳3上的开口进行配合,实现将主体固定部固定在后壳3上。
而设置在主体固定部64的侧部接触段604上的锁紧销62能够通过嵌入后壳3上的定位孔,进一步增加主体固定部64在后壳3上进行固定的稳定性。这样的设计方式,非常巧妙的利用虚拟现实设备自身的形态特点,特别针对具有眼镜形态的虚拟现实设备,结合图30和图31可知,在固定的时候设置在过渡面6412靠近中部接触段605位置的卡扣61与虚拟现实设备上的脸托固定件41配合进行卡扣固定,而设置在后壳贴合面6411靠近侧部接触段604位置的锁紧销62与虚拟现实设备上的定位孔43嵌入固定,由于脸托固定件41和锁紧销62不在同一个面上,并且脸托固定件41采用卡扣的固定,会向内存在一个拉力,这样可以防止定位孔43在嵌入后脱落出来。并且由于锁紧销62的结构为柱体,而脸托固定件41为具有腔体的卡扣,在配戴过程中,重量的首先会施加在锁紧销62上,这样可以保证脸托固定件41不容易被破坏掉。
采用一端卡扣,一端嵌入固定的方式,在保整个脸托能与虚拟现实设备牢固固定的同时,还能方便安装或拆卸。在本申请的部分实施例中,在面部接触部63的凸缘602、中部接触段605以及侧部接触段604的连接侧634内缘631上,以及凸缘602的连接侧634外缘632上设有限位凸台65。限位凸台65凸出设置在内缘631和部分外缘632上。限位凸台65凸起的高度与主体固定部64的厚度保持一致。即在面部接触部63与主体固定部64固定在一起后,限位凸台65的顶端与主体固定部64的后壳侧641边缘平齐。这一结构可以使,面部接触部63在受到压力作用,产生的形变得到缓冲,减轻长时间佩戴过程中面部接触部63容易从主体固定部64上剥离的问题。
另外,通过设置限位凸台65,可以方便将面部接触部63安装到主体固定部64上。一般的情况下,面部接触部63为软性材质,并且限位凸台65也为软性材质,而为增加与虚拟现实设备的连接牢固性,主体固定部64采用具有一定硬度的材质,限位凸台65的设置能够充分的将主体固定部64包裹起来,即让整个脸托与用户接触的面都是比较软性的材质,增加用户的舒适度。
在一种技术方案中,槽底面6381的宽度在中部接触段605过渡到侧部接触段604的方向上逐渐增大。应该说明的是,此处的宽度是指垂直于槽底面6381的切线方向上,槽底面6381两个边缘之间的距离。在本实施例中,槽底面6381的宽度在中部接触段605过渡到侧部接触段604的方向上逐渐增大,可以增加与虚拟现实设备后壳的接触面积,进而提高脸托在虚拟现实设备后壳3上的稳定性以及用户在配戴虚拟现实设备时压力均匀传递。
由于在中部接触段605的位置上,承受整个虚拟现实设备的重量较小,并且 由于上述实施例中对称设置的卡扣61能够将中部接触段605对应的脸托实体牢牢的固定在后壳3上,因此这部分相对稳定,可以适当减小槽底面6381的宽度。另外,由于光学模组和镜架的限制,以及人体鼻部的结构特性,使得此部分没有足够的空间容纳较宽的槽底面6381。而对于侧部接触段604,其承受虚拟现实设备本身的重力作用较明显,为了将重力分担在面颊部位,在侧部接触段604需要保持准确的位置限定。因此本实施例中,将槽底面6381在侧部接触段604位置设置的较宽,以便于脸托在该区域的固定。
对于本申请的部分实施例,内缘631与外缘632之间的距离在中部接触段605,沿远离凸缘602方向逐渐增大。本实施例中,内缘631与外缘632之间的距离是指,在垂直于内缘631或外缘632的切线方向上,内缘631的边缘到外缘632的边缘之间的距离,即面部接触部63的整体宽度。这一距离在中部接触段605,沿远离凸缘602方向逐渐增大,可以适应虚拟现实设备的结构特点,并使整体结构趋于更加稳定。在槽底面6381的宽度逐渐增大的前提下整体宽度的增大可以确保具有足够的空间用于设置贴合面636,使佩戴者的面部与贴合面636的接触面积增大,便于分散重力作用,减轻佩戴者在长期佩戴过程中产生的不适感。而内缘631与外缘632之间的距离在侧部接触段604,沿远离中部接触段605方向先增大后减小,一方面上述距离先逐渐增大可以增大贴合面636的面积,另一方面,上述距离后逐渐减小可以减轻末端606的重量。
本申请还提供一种虚拟现实设备,包括前壳1、后壳3以及上述实施例提供的脸托6,其中:
如图31所示,对于本申请提供的虚拟现实设备,其后壳3上设有用于连接脸托6主体固定部64的主体贴合面31;以及连接主体贴合面31的辅助定位面32。主体贴合面31相对于辅助定位面32倾斜设置,其倾斜程度的变化规律是与上述实施例中主体固定部64的过渡面6412相对于后壳贴合面6411倾斜程度的变化规律相同。由于整个脸托6在安装到后壳3上时,不能完全贴合覆盖到整个主体贴合面31,因此在脸托6两侧末端606对应的位置上,主体贴合面31平滑连接到虚拟现实设备的中框301。
进一步地,辅助定位面32是与后壳贴合面6411贴合的平面,辅助定位面32从主体贴合面31延伸到虚拟现实设备的中框301位置。辅助定位面32作为后壳3上的背板,在后壳3上形成用于固定的平面,其中,在中部接触段605对应的区域上,光学组件与辅助定位面32之间的主体贴合面31宽度变化规律,与上述实施例中槽底面6381的宽度变化规律相同,并且在主体贴合面31与光学模组之间的距离,应足够容纳主体固定部64的后壳贴合面6411,即在整个脸托6安装在后壳3上时,不遮挡光学模组的前提下,保证足够的稳定性。
整个脸托固定在虚拟现实设备的后壳3上的方式可以为粘贴固定,或者可拆卸固定,为了便于清洁维护,以及不同用户的使用等,固定方式为可拆卸固定。例如主体贴合面31上设有相对于中心线601对称的至少两个脸托固定件41,脸托固定件41与锁紧件60适配,将主体贴合面31与主体固定部64连接。应当说明的是,脸托固定件41与锁紧件60适配是指,根据锁紧件60的形式,在对应的安装位置上设置相应形式的配合器件,例如,当锁紧件60是卡扣时,则对应的脸托固定件41为卡槽;当锁紧件60是螺钉时,则对应的脸托固定件41为螺纹孔,当锁紧件60为锁紧销时,则对应的脸托固定件41为定位孔。
另外,对于脸托固定件41和锁紧件60的数量,应保证至少两个,且两个相对于中心线601对称,对称设置的脸托固定件41和锁紧件60能够平衡中心线601两侧的作用力,使主体固定部64贴合到主体贴合面31时避免产生缝隙,影响整体的稳定性。但脸托固定件41和锁紧件60的数量也不宜过多,因为主体固定部64通常是由具有弹性的塑料材质制成,且在中部接触段605的位置上,比较纤细,受到较小的力就能产生变形,而当设置了较多数量的脸托固定件41和锁紧件60时,会因为制造误差而产生内应力,相应的会使脸托6整体上产生形变,改变原本作用力的分散规律,不仅影响佩戴的体验,还有可能导致脸托6的损坏。
本申请提供的虚拟现实设备中,前壳1与后壳3的外形相同,前壳1和后壳3连接形成用于收纳光学组件和电子器件的腔体。前壳1与后壳3组成虚拟现实设备的主体,其中,容纳屏幕、电子元器件、PCB板以及光学组件,并且在形成的主体两侧分别设置有镜腿以及用于数据传输的接口等,通过电子器件和光学组件的配合,将影像呈现在佩戴者的两眼正前方。
在本申请的部分实施例中,如图31所示,脸托固定件41为设置在主体贴合面31上的开口,用于嵌入卡扣61。在实际使用中,主体固定部64上的卡扣61嵌入到开口,由材料本身的弹性作用卡合在开口中,实现主体固定部64在后壳3上的固定。
为了进一步增加主体固定部64的稳定性,辅助定位面32上还设有与锁紧销62数量相同,且位置对应的定位孔43;定位孔43用于嵌入锁紧销62。由于塑料材质本身容易变形,当通过脸托固定件41与锁紧件60的配合固定在后壳3上时,容易在两侧末端相对于主体贴合面31微微翘起,影响佩戴的舒适感和稳定性,因此在主体固定部64的侧部接触段604上设置锁紧销62,并通过过盈配合插入定位孔43可以配合脸托固定件41对主体固定部64进行固定,使脸托6在虚拟现实设备上更加稳定。
以上实施例中,不仅局限于虚拟现实设备,还可应用于任何头戴设备,且所述头戴设备具体包括但不限于虚拟现实设备、增强现实设备、游戏设备、移动计 算设备以及其它可穿戴式计算机等。
由以上技术方案可知,本申请提供一种虚拟现实设备的脸托配件,其中,脸托6在实际使用中,安装在虚拟现实设备的中部与佩戴者鼻部接触的位置上。通过脸托6中面部接触部63的几字形结构,使脸托6与佩戴者的鼻部两侧和面颊两侧接触,将虚拟现实设备的重量分担至鼻梁和面部,减轻虚拟现实设备在佩戴时,因为压力的聚集而使佩戴者产生的不适感。
本申请提供的脸托6,由连续的贴合曲线635划分而成的贴合面636和外缘支撑面637,分别与佩戴者面部以及虚拟现实设备的镜头模组配合,并且贴合面636与槽底面6381形成的内倾角α在整个面部接触部63上连续变化,在凸缘602过渡到中部接触段605再到侧部接触段604的过程中,内倾角α先逐渐增大后逐渐变小,使得脸托6的贴合面636与鼻侧和面颊充分贴合。这样的结构可以使面部承受虚拟现实设备的压力基本趋于一致,不仅可以达到舒适的佩戴感觉,而且可以使虚拟现实设备在佩戴时更加稳定。此外,贴合面636与面部的充分贴合还能减少贴合部位的漏光,提高观影效果的同时避免使用面积较大的遮光罩,从而减轻虚拟现实设备整体的重量,便于稳定虚拟现实设备,解决传统虚拟现实设备长时间佩戴容易从面部滑落的问题。
本申请提供的实施例之间的相似部分相互参见即可,以上提供的具体实施方式只是本申请总的构思下的几个示例,并不构成本申请保护范围的限定。对于本领域的技术人员而言,在不付出创造性劳动的前提下依据本申请方案所扩展出的任何其他实施方式都属于本申请的保护范围。
