所述第二配光件用于接收所述光线，并将所接收的所述光线汇集于一个焦点，并自所述焦点通过所述出光孔投射至所述壳体之外。
本申请采用的技术方案能够达到以下有益效果：
本申请实施例公开的电子设备通过对相关技术中的电子设备中的结构进行改进，通过在错位分布的发光件与出光孔之间设置第一配光件和第二配光件，由于第一配光件能够接收并调节发光件发射的光线，并使得光线能够朝出光孔所在的一侧偏移后再投射至第二配光件上，从而使得第一配光件可对发光件发射的光线实现初步矫正，而投射至第二配光件的光线能够在第二配光件中汇聚于一个焦点，相当于使得光线从更加邻近出光孔的焦点投射出，从而使得光线能够在第二配光件中实现光路交叉，从而使得经过第二配光件再通过出光孔投射在壳体之外的光线的出光角度以及出光量均较大，用以提升电子设备的红外遥控性能。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例公开的电子设备进行详细地说明。
如图1至图8所示，本申请实施例公开一种电子设备，所公开的电子设备包括壳体100、发光件200、第一配光件300和第二配光件400。
其中，壳体100为电子设备的基础构件，能够对电子设备的内部构件发挥防护作用，壳体100设有内腔110和与之连通的出光孔120，出光孔120 连通内腔110与外界环境。发光件200能够发出光线，具体的，发光件可以是红外发光二极管。第一配光件300与第二配光件400均能够对光线的传输路径实现矫正作用。发光件200和第一配光件300设于内腔110中，第二配光件400位于壳体100内，且第二配光件400的至少部分安装于出光孔120内。
发光件200与出光孔120错位分布，也就是说，发光件200的光轴与出光孔120的中心轴线在垂直于光轴的方向上具有一定的距离，从而使得发光件200与出光孔120之间为偏心设置，当然，在发光件200的光轴方向上，发光件200与出光孔120之间也具有大于零的距离。在此种情况下，发光件200发射出的较大部分的光线均较难直接从出光孔120中射出，即使得出光孔120中射出的光线的出光量较少，且出光孔120中射出光线的出光角度较小。
为使得发光件200发射出的大部分的光线能够以较大的出光角度从出光孔120射出至壳体100之外，用以对电视等设备实现红外遥控功能。在本申请中，第一配光件300能够接收并调节发光件200发射的光线，并使得光线朝偏向出光孔120所在的一侧传输后投射至第二配光件400的第二入光面420，接着，第二配光件400能够接收光线，并将所接收的光线汇集于一个焦点，从而使得发光件200中的光线在经过第一配光件300与第二配光件400的配光后在第二配光件400中汇聚于一个焦点处，从而使得光线能够在第二配光件400实现光路交叉，这相当于将发光件200的位置移动至第二配光件400中，而实现光路交叉的光线在能够增大出光角度的同时，还能够使得光线较为集中，从而有利于减小出光孔120的孔径大小。
需要补充的是，光线在第二配光件400的作用下能够汇集于一个焦点，即实现光路交叉。这个焦点是个虚拟的焦点，在光学领域中，可以通过设计第二配光件400的第二入光面420的面型，从而实现光线汇集于这个焦点。汇集于这个焦点的光线会接着从出光孔120射出，此过程中，汇集的焦点是 在第二配光件400中实现，故这个焦点更邻近出光孔120，在此种情况下，这个焦点的形成相当于把发光件200朝着靠近出光孔120的方向移动了一定的距离，使得发光件400能够在更靠近出光孔120的位置向出光孔120中投射光线，从而能够缓解出光孔120对发光件400的光线投射的遮挡，进而有利于增大实际从出光孔120中投射出的光线的出光角。
相较于发光件200与出光孔120之间的距离，第二配光件400与出光孔120之间的距离更近，从而使得汇聚于焦点的光线在通过出光孔120投射至壳体100之外的情况下，光线可以具有较大的出光量和较大的出光角度。也就是说，本申请设置的第一配光件300与第二配光件400可以解决发光件200与出光孔120具有较大偏心距离的情况下，电子设备的红外遥控性能变差的问题。
第一配光件300能够在一定程度上发挥矫正光线的作用，而第二配光件400则能够使得从第一配光件300投射出的光线汇集于更靠近出光孔120的焦点，进而缓解出光孔120对出光角的限制。当然，也能够使得发光件200发出的光线更多地被纠偏后从出光孔120投射出。
本申请实施例公开的电子设备通过对相关技术中的电子设备中的结构进行改进，通过在错位分布的发光件200与出光孔120之间设置第一配光件300和第二配光件400，由于第一配光件300能够接收并调节发光件200发射的光线，并使得光线能够朝向出光孔120所在的一侧偏移后再投射至第二配光件400上，从而使得第一配光件300可对发光件200发射的光线实现初步矫正，而投射至第二配光件400的光线能够在第二配光件400中汇聚于一个焦点，从而使得光线能够在第二配光件400中实现光路交叉，从而使得经过第二配光件400再通过出光孔120投射在壳体100之外的光线的出光角度以及出光量均较大，用以提升电子设备的红外遥控性能。
具体的，第一配光件300可以为弯折的导光柱，导光柱通过自身的结构折弯从而来调节光线的走向，从而达到纠偏的作用，即弥补发光件200与出 光孔120之间的偏离。当然，为了简化结构，第一配光件300可以具有第一出光面310，第一出光面310为朝向第二配光件400凸起的第一凸面，第一凸面的形成使得第一配光件300整体类似于一个凸透镜，从而通过光的折射实现对光线路径的调节。当然。第一凸面能够在一定程度上辅助光线汇集，从而使得投射至第二配光件400的光线已经预先汇集到一定的程度，接着在第二配光件400的作用下，更有利于使得光线投射至第二配光件400中之后汇集于一个焦点。
第二配光件400具有第二入光面420，第二入光面420可以为朝向第一配光件300凸起的第二凸面，此种情况下，具有第二凸面的第二配光件400也类似于一个凸透镜，从而更有利于光线在投射到其中后汇集于一个焦点。当然，实现光线汇集于焦点的光学结构有多种，本申请不限制第二配光件400的具体结构。
在本申请实施例公开的电子设备中，第一配光件300可以具有第一出光面310，第一出光面310可以包括第一子出光面311和第二子出光面312，第二子出光面312围绕第一子出光面311设置，第二子出光面312的曲率大于第一子出光面311的曲率。
在此种情况下，曲率较大的第二子出光面312对光线具有较强的偏折能力，即第二子出光面312对光线的偏折角度较大，而曲率较小的第一子出光面311对光线的偏折能力较弱，即第一子出光面311对光线的偏折角度较小，从而使得第一子出光面311和第二子出光面312对第一出光面310上的光线具有不同的偏折能力。由于第二子出光面312围绕第一子出光面311设置，从而使得第二子出光面312与第一子出光面311对光线的偏折方向可以不同，从而使得第二子出光面312有利于将光线向靠近第一子出光面311的方向实现偏折，进而有利于将经过第一配光件300的光线进行聚拢，用以避免第一配光件300对发光件200射出的光线过度扩展。
可选的，发光件200射出的有效光线的宽度为可以第一宽度，第一出光 面310射出的有效光线的宽度可以为第二宽度，第二宽度与第一宽度的比值可以小于1.35，从而避免第一配光件300对发光件200射出的光线扩展宽度较大而对光线的利用率降低。需要说明的是，本文中，宽度指的是相应的对象在垂直于光轴X1方向的平面内的最大尺寸。
在本申请实施例公开的电子设备中，第一配光件300和第二配光件400之间可以具有间隙，从而能够避免第一配光件300与第二配光件400之间直接接触，从而能够避免在电子设备被晃动或是被碰到的情况下，第一配光件300与第二配光件400之间发生相互碰撞，进而导致第一配光件300与第二配光件400之间发生位置的移动而影响对发光件200的配光效果，或者，甚至导致第一配光件300与第二配光件400之间由于碰撞而造成两者的损坏，进而影响电子设备的红外遥控性能。
在本申请实施例公开的电子设备中，第一配光件300可以具有第一入光面320，比如，第一入光面320可以为锯齿面。在此种情况下，锯齿面有利于对光线的路径实现调整，从而能够方便将穿过第一配光件300的光线朝向出光孔120的方向进行引导。锯齿面的锯齿角度的大小可以根据对光线的偏折角度的调整需要进行具体设置，本申请不对锯齿面的锯齿角度的大小进行具体限制。
在一种可选的技术方案中，锯齿面可以包括锯齿斜面321，锯齿斜面321与发光件200的光轴X1之间的夹角可以为60±2°，也即58°～62°。在此种情况下，具体的，锯齿斜面321与发光件200的光轴X1之间的夹角可以为60°，用以实现对发光件200射出光线进行一定角度的偏折。需要说明的是，锯齿斜面321与发光件200的光轴X1之间的夹角还可以为58°或61°等角度，本申请不对锯齿斜面321与发光件200的光轴X1之间的角度进行具体限制，并且，发光件200的光轴X1与出光孔120的中心轴线X2相互平行。当然，锯齿面还可以包括锯齿直面322，在靠近出光孔120的边缘，锯齿直面322与锯齿斜面321相交，锯齿直面322与光轴X1之间相互平行， 从而使得锯齿斜面321与锯齿直面322之间的夹角可以为60±2°。
为使得第二入光面420能够较为方便地接收到从第一出光面310中射出的光线，在进一步的技术方案中，电子设备还可以包括显示屏幕500，第二入光面420可以为半球面，第二入光面420的中心的切平面与锯齿斜面321相互平行，锯齿斜面321与出光孔120的中心轴线X2之间的夹角为锐角，第二入光面420远离显示屏幕500的一侧的边缘与出光孔120的距离，小于第二入光面420的邻近显示屏幕500的另一侧的边缘与出光孔120的距离。在此种情况下，入射至锯齿斜面321上的光线向着中心轴线X2的方向实现偏折，并且由于第二入光面420远离显示屏幕500的一侧的边缘与出光孔120的距离，小于第二入光面420的邻近显示屏幕500的另一侧的边缘与出光孔120的距离，从而使得与显示屏幕500距离较近的部分第二入光面420对于从第一出光面310射出的光线具有较大的接收面积，从而能够有利于对锯齿斜面321射出的偏折光线实现接收。
考虑到用户在使用电子设备的红外遥控功能时，会习惯性地将电子设备具有出光孔120的端部向上方扬起一个角度，而需要被遥控产品(例如电视机)通常在出光孔120的下方，所以需要出光孔120中的光线向位于下方的被遥控产品射出。为使得出光孔120中射出的光线能够向下方射出，在本申请实施例公开的电子设备中，第二配光件400可以具有第二出光面410，第二出光面410为第一平面，出光孔120的出光端口所在的平面为第二平面，第一平面与第二平面之间形成第一夹角，第一夹角的角度范围为1°～3°。在此种情况下，第二平面为壳体100的外表面所在的平面，而第一平面与第二平面之间具有夹角，则说明第一平面相对于第二平面倾斜设置，而倾斜设置的第一平面有利于将光线进行偏折，从而使得从出光孔120中射出的光线能够较为容易地发射至被遥控产品上。
具体的，第一平面与第二平面之间的角度可以为2°。当然，第一平面与第二平面之间的角度还可以是1°或是3°等，本申请不对第一平面与第二 平面之间的具体角度进行限制。并且，由于第一平面只是小角度的倾斜设置，从而使得用户几乎不能观察到第一平面相对于第二平面倾斜设置，这有利于用户的使用感受。相比于将第一平面设置为纹面对光线实现偏折的设置，较为光滑的第一平面有利于满足电子设备的精致外观需求。
在进一步的技术方案中，第二出光面410可以内凹于出光孔120。在此种情况下，相对于出光孔120来说，第二出光面410形成的第一平面为回缩结构，从而能够防止倾斜设置的第一平面凸出于出光孔120，进而能够有利于实现对第一平面的防护。
在本申请实施例公开的电子设备中，第二入光面420可以包括全反射结构面，全反射结构面用于接收光线，并将所接收的光线汇集于焦点。在此种情况下，全反射结构面的设置能够对投射至第二入光面420中的光线实现全部反射，有利于提升对发光件200中射出光线的利用率。
在本申请实施例公开的电子设备中，壳体100可以包括框体130、内部支撑架140和电路板150，其中，内部支撑架140设于框体130内，电路板150固定于内部支撑架140上，发光件200安装于电路板150上，第一配光件300安装于内部支撑架140上，第二配光件400安装于框体130上，出光孔120开设于框体130。在此种情况下，框体130可作为电子设备的安装基础，从而使得内部支撑架140能够设置于框体130上，同时，内部支撑架140也能够作为其他构件的安装基础，从而使得第一配光件300能够安装于内部支撑架140上，电路板150能够实现电子设备内部的电路连接与控制，能够对发光件200提供电能。
电子设备中还可以包括电池盖170和显示屏幕500等部件，电池盖170安装于框体130上，显示屏幕500安装于内部支撑架140上。显示屏幕500所在的平面垂直于电子设备的厚度方向实现安装。
在实现电子设备装配的过程中，第二配光件400与框体130之间产生装配间隙160，为使得第二配光件400与框体130之间的连接稳定性较好，可 在装配间隙160填充有粘贴胶，粘贴胶例如可以是光敏胶，从而使得在减少间隙的同时，还能够提升第二配光件400与框体130之间的连接稳定性。
本申请实施例公开的电子设备可以是手机、掌上电脑、游戏机以及电子阅读器等，本申请不对电子设备的具体种类进行限制。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
