实施方式
下面结合附图和实施例对本申请作详细说明。可以理解的是，此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
实施例一
图2a为本申请实施例一提供的一种激光电视的结构示意图，图2b为图2a中提供的激光电视在不使用时沿A1-A2的剖面图，图2c为图2a中提供的激光电视在使用时沿A1-A2的剖面图。如图2a、2b和2c所示，该激光电视，包括：激光电视主机10，在激光电视主机10上设置有容纳凹槽20；镜头30，以及与镜头30固定连接的升降机构40，均设置于容纳凹槽20内，升降机构40用于带动镜头30升降，以使镜头30在工作时凸出激光电视主机10的上表面11。
上述升降机构40的结构有多种，例如，该升降机构40可以包括链条和与链条固定连接的支撑板，镜头固定设置在支撑板上，在使用时，通过改变链条缠绕在固定轴上的匝数，改变链条的长度，进而使得镜头30在工作时凸出激光电视主体10的上表面11。
图2b给了另一种升降机构的结构示意图。如图2b所示，该升降机构40包括升降支架41和支撑平台42；镜头30固定设置在支撑平台42上，升降支架40的一端与容纳凹槽20底面21固定连接，另一端与支撑平台42固定连接。可选地，该升降支架41为剪叉式升缩支架。本领域技术人员可以理解，在本实施例中升降支架的形式包括但不限于上述剪叉式升缩支架。
当需要使用时，调节该升降机构40的高度，使得该升降机构40沿由容纳凹槽20底面21指向激光电视主机10上表面11的方向伸展，进而带动镜头30沿由容纳凹槽20底面21指向激光电视主机10上表面11的方向运动，直至镜头30凸出电视主机10的上表面11(如图2c)。当不使用时，调节该升降机构40的高度，使得该升降机构40沿由激光电视主机10上表面11指向容纳凹槽20底面21的方向收缩，进而带动镜头30沿由激光电视主机10上表面11指向 容纳凹槽20底面21的方向运动，直至镜头30的上表面低于激光电视主机10的上表面11，即镜头30完全容纳于容纳凹槽20内部(如图2b)。
本实施例通过将镜头以及与所述镜头固定连接的升降机构均设置于激光电视主机上的容纳凹槽内，利于升降机构的可升降功能，带动所述镜头的升降，进而使所述镜头在工作时凸出所述激光电视主机的上表面，以实现电视节目放映功能，在不工作时完全容纳于容纳凹槽内，防止其被损坏，解决了现有的激光电视镜头始终突出于激光电视的外表面，既影响美观又易被损坏，导致用户体验差的问题，实现了提高用户体验的目的。
在上述技术方案的基础上，可选地，升降机构40还包括驱动模块，用于驱动升降支架41运行，以带动镜头30升降。该驱动模块可以为手动驱动模块，也可以为电动驱动模块。若该驱动模块为电动驱动模块，可选地，驱动模块还可以包括驱动开关，驱动开关设置在激光电视主机10的外壳体上，用于控制驱动模块的开启和关闭，进而控制驱动模块驱动升降支架41伸展或收缩，以带动镜头30升降。或者，驱动模块还可以包括开关信号接收模块，用于接收驱动开关信号。可选地，驱动开关信号可以为与激光电视配套的遥控器所发射的用于控制激光电视开启或关闭的信号。
实施例二
本实施例为以实施例一提供的技术方案为基础的一个优化方案。与实施例一相比，本实施例提供的激光电视还包括盖体，设置于所述激光电视主机的容纳凹槽上方；或者，所述镜头上的除出光侧外的一部分复用为所述盖体。图3a和图3b给出了两种包含盖体的激光电视的结构示意。如图3a和3b所示，该激光电视，包括：激光电视主机10，在激光电视主机10上设置有容纳凹槽20；镜头30，以及与镜头30固定连接的升降机构40，均设置于容纳凹槽20内，升降机构40用于带动镜头30升降，以使镜头30在工作时凸出激光电视主机10的上表面11。在图3a中，盖体50设置于激光电视主机10的容纳凹槽20上方。在不使用激光电视时，将盖体50盖合在该容纳凹槽20的上方；在使用激光电视时，将盖体50从该容纳凹槽20的上方取下。在图3b中，镜头30上除出光侧外的一部分复用为盖体50。在不使用激光电视时，镜头30与激光电视主机10上表面11平行侧与激光电视主机10上表面11位于同一平面内，此时，镜头30靠近容纳凹槽20开口处充当盖体50。
可选地，还可以将盖体优化为柔性遮盖膜。如图4a所示，激光电视主机10上表面包括柔性遮盖膜60，柔性遮盖膜60上设置有与镜头30对应的切口61。在使用时，升降机构40带动镜头30向远离容纳凹槽20底面的方向运动，使得切口61处的柔性遮盖膜60发生形变弯曲，进而形成一个可以允许镜头30所发出的光线穿出可缺口(如图4b)。
本实施例技术方案，通过在容纳凹槽上方设置盖体，在不使用激光电视时，利用盖体将容纳凹槽盖合，可以防止灰尘以及液体等落入到容纳凹槽内或镜头上，可以更好地保护镜头。
可选地，可选地，如图5a，镜头30上与出光侧相对的末端固定在激光电视主机10内部的旋转轴12上，在使用时，升降机构40驱动镜头30的出光侧绕旋转轴12转动，以使镜头30在工作时凸出激光电视主机10的上表面11(如图5b)。
注意，在不冲突的情况下，上述实施例中的特征可以任意组合；上述仅为本申请的可选实施例及所运用技术原理。本领域技术人员会理解，本申请不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本申请的保护范围。因此，虽然通过以上实施例对本申请进行了较为详细的说明，但是本申请不仅仅限于以上实施例，在不脱离本申请构思的情况下，还可以包括更多其他等效实施例，而本申请的范围由所附的权利要求范围决定。
工业实用性
本申请实施例通过将镜头以及与所述镜头固定连接的升降机构均设置于激光电视主机上的容纳凹槽内，利于升降机构的可升降功能，带动所述镜头的升降，进而使所述镜头在工作时凸出所述激光电视主机的上表面，解决了现有的激光电视镜头始终突出于激光电视的外表面，既影响美观又易被损坏，导致用户体验差的问题，实现了提高用户体验的目的。
