具体实施方式
为了使本技术领域的人员更好地理解本申请的技术方案，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。

请参阅图1，本申请实施例提供一种投影装置100，投影装置100包括投影装置主体101和盖门组件200，盖门组件200连接于投影装置主体101。其中，投影装置主体101包括镜头1011，镜头1011与盖门组件200相对设置，盖门组件200可选择性地遮蔽或显露镜头1011。需要说明的是，投影装置主体101还可以包括内部结构件，如光机、控制主板等，其中光机、控制主板等内部结构件的结构、连接关系可参考现有技术，在此不做赘述。

其中，壳体10设有显露孔110，壳体10收容投影装置主体101时，投影装置100的镜头1011经由显露孔110显露。第一导轨组件40以及第二导轨组件70固定于壳体，第一盖体20和第二盖体50均可活动地连接于壳体10，第一盖体20和第二盖体50并列设置时共同封盖显露孔110。其中，驱动机构30 分别连接于第一盖体20和第二盖体50，具体而言，驱动机构30包括连接于第一导轨组件40的第一传动组件310和连接于第二导轨组件70的第二传动组件610，第一盖体20连接于第一传动组件310，并在第一传动组件310的导引下可相对壳体10活动。第二盖体50连接于第二传动组件610，并在第二传动组件610的导引下可相对于壳体10活动。例如，当显露显露孔时，第一盖体20和第二盖体50分别由第一传动组件310和第二传动组件610导引而沿第一方向移动，且在垂直于第一方向的第二方向，第一盖体20和第二盖体50分别由第一传动组件310和第二传动组件610导引而相互远离。
请再次参阅图1，为了清楚地描述第一盖体20和第二盖体50的运动方向，在本实施例中，以图1中显示的方向作为示例性描述，竖直方向上以镜头1011为基准点，运动时竖直方向靠近镜头1011的方向定义为向下运动，运动时沿竖直方向远离镜头1011的方向定义为向上运动。水平方向上以嵌入显露孔110的第一盖体20为基准点，运动时沿水平方向由第一盖体20指向第二盖体50的方向定义为向后运动，运动时沿水平方向由第二盖体50指向第一盖体20的方向定义为向前运动。例如，第一盖体20向下运动以及向后运动的轨迹为，第一盖体20沿竖直方向靠近镜头1011，同时也沿水平方向靠近第二盖体50运动。当盖门组件200开启时，第一盖体20以沿着向下运动以及向后运动的轨迹运动，第二盖体50以沿着向上运动以及向后运动的轨迹运动以避让第一盖体20，从而使镜头1011顺利显露。需要说明的是，本实施例中，以第一盖体20和第二盖体50沿水平方向运动为第一方向，以第一盖体20和第二盖体50沿竖直方向运动为第二方向，此时，第二方向大致垂直于第一方向。

本实施例中，第二驱动件620为电机，第二传动组件610包括依次连接的第二齿轮611、第二齿条612和第二连接件613。需要说明的是，第二齿条612和第二连接件613可以作为第二传动组件610的执行端，以带动第二盖体50运动。
请一并参阅图3和图4，第二齿轮611可转动地设置于第二导轨板710，第二齿条612与第二齿轮611相啮合，并可滑动地与第三导轨711相配合。进一步地，第二齿条612上可以凸伸地设置有第二导向柱6121，第二导向柱6121凸伸入第三导轨711中，以实现第二齿条612与第三导轨711的滑动配合。第二连接件613连接于第二盖体50与第二齿条612之间。第二驱动件620连接于第二齿轮611，当第二驱动件620启动时，其驱动第二齿轮611转动，带动第二齿条612沿着第三导轨711运动，从而驱使第二连接件613带动第二盖体50相对壳体10运动。
本实施例中，当第二盖体50嵌入显露孔110时，认为第二盖体50处于初始状态。此时，第二齿条612与第三导轨711的第三导向部7111配合。具体而言，第二盖体50处于初始状态下，第二齿条612的第二导向柱6121位于第三导向部7111远离第三延展部7112的一端。此时，第二齿条612沿着第三导轨711运动，具体为第二齿条612沿第三导向部7111朝向第三延展部7112运动时，第二盖体50相对壳体10运动的轨迹大致为，向上运动以及向后运动。由于第一盖体20的运动轨迹大致为向下运动以及向后运动或大致为向后运动，则第二盖体50通过大致为向上运动以及向后运动的运动轨迹可以避让第一盖体20，使得第一盖体20可以顺利地开启以显露镜头1011。也即，显露镜头1011时，第一盖体20和第二盖体50分别由驱动机构30驱动而沿第一方向移动，且在垂直于第一方向的第二方向，第一盖体20和第二盖体50分别由驱动机构驱动30而相互远离。
需要说明的是，本实施例中，第二导轨组件70包括两个第二导轨板710，因此，第二齿轮611、第二齿条612、第二连接件613均相应地设置为两个。
进一步地，两个第二齿轮611之间通过第二连动组件630连接，以便通过 设置单一的第二驱动件620即能同时驱动两个第二齿轮611运动，从而减少控制单元和生产成本。其中，第二连动组件630可以包括第二传动杆(图中未标出)、第二传动皮带(图中未标出)和第二皮带轮(图中未标出)。
具体地，第二传动杆可转动地连接于壳体10，两个第二皮带轮分别连接于两个第二齿轮611，两个第二传动皮带分别设于第二传动杆的两端，且每个第二传动皮带连接于第二传动杆与对应的第二皮带轮之间，便可以将其中一个第二齿轮611转动运动传递到另一个第二齿轮611。在本实施例中，通过设置成对的第二导轨板710和成对的第二传动组件610，可以在带动第二盖体50运动时，给予第二盖体50相对两边平衡的作用力，使得第二盖体50在运动过程不会因受力不平衡而朝向一边倾斜，影响第二盖体50的运动效果。
本申请提供的投影装置100及盖门组件200，包括可相对壳体10运动的第一盖体20和第二盖体50，在盖门组件200开启时，可以将第二盖体50相对壳体10移动，能够为第一盖体20的运动提供更大的运动空间，避免第一盖体20因运动空间不足而开启卡壳或开启失败的现象产生。
进一步地，请参阅图1，盖门组件200还包括距离传感器80，距离传感器80设置于第二盖体50。其中，距离传感器80用于采集第二盖体50与投影装置主体101的指定部位之间的相对距离，以确定是否允许第二传动组件610控制第二盖体50运动。
其中，指定部位可以为最接近第二盖体50的内部结构件靠近第二盖体50的一侧所在的平面。例如，投影装置主体101可以具有参考面1013(如图1所示)，参考面1013与第二盖体50相对设置，则可将参考面1013作为上述的指定部位。
在另一些实施方式中，距离传感器80可以设置于其他能够获取到第二盖 体50与指定部位的相对距离的地方，如投影装置主体101上与第二盖体50相对的位置。
在本实施方式中，距离传感器80可以为光学传感器、红外传感器或声波传感器等，通过发射光脉冲、红外线或声波，并根据接收到反射回来的光脉冲、红外线或声波的时间，可以得出第二盖体50与指定部位的相对距离，在此不做赘述。
在本实施例中，定义第二盖体50嵌入显露孔110时为第二盖体50的初始状态。出厂时设定第二盖体50处于初始状态时，第一盖体20能不受阻碍地运动至第二盖体50和指定部位之间，将此时第二盖体50与投影装置主体101的指定部位之间的相对距离定为预设距离。在实际使用过程中，第二盖体50可能会由于塑形形变而产生弯曲，进而第二盖体50与指定部位的相对距离会小于预设距离，从而阻碍或阻挡第一盖体20的运动。需要说明的是，本申请的滑盖门组件200可以根据第二盖体50的形变状态控制第二盖体50运动，以避让第一盖体20。例如，可以通过获取第二盖体50与指定部位之间的相对距离，并与预设距离进行比对，从而判断第二盖体50是否需要进行运动以避让第一盖体20的运动路径，使得第二盖体50不会阻挡第一盖体20的运动。
进一步地，因为第一盖体20的运动轨迹是确定的，第二盖体50出厂时初始状态的位置是确定的，且投影装置主体101的指定部位的位置和大小也是确定的，所以预设距离为确定值，其数值是有效可靠的。只是在使用过程中，第二盖体50可能会因为外界因素，如外力影响发生形变，或因自身内应力发生形变，进而第二盖体50与指定部位的相对距离会发生变化，所以需要将获取到的相对距离与预设距离进行比对，从而判断是否需要控制第二盖体50运动。
在本实施例中，若获取的相对距离小于预设距离，说明第一盖体20按原 路径运动时会被第二盖体50阻挡，此时可以控制第二盖体50进行运动以避让第一盖体20。若获取的相对距离大于预设距离，说明第一盖体20按原路径运动时不会被第二盖体50阻挡，此时可以控制第二盖体50维持初始状态。需要说明的是，通过设置距离传感器80，可以实现对第二盖体50的智能控制。
本申请实施例还提供一种盖门组件控制方法，其可以应用于上述实施例中所提供的投影装置。其中，投影装置包括投影装置主体和盖门组件，盖门组件连接于投影装置主体。其中，投影装置主体包括镜头，盖门组件可选择性地遮蔽或显露镜头。进一步地，盖门组件包括壳体、第一盖体和第二盖体，第二盖体设有距离传感器。上述盖门组件控制方法，通过距离传感器获取第二盖与相对于投影装置主体的位置信息，进而确定盖门组件的开启方案，控制盖门组件开启。
具体地，请参阅图6，本申请提供的盖门组件控制方法包括：
S101：获取盖门组件的开启指令。
其中，盖门组件的开启指令是指对于盖门组件输入的控制第一盖体开启以显露镜头的指令。例如，用户使用投影装置时，需要通过控制盖门组件的运动，进而使设于投影装置主体的镜头通过显露孔显露，此时，用户可以通过遥控器或控制按钮等对盖门组件输入开启指令。
S102：获取第二盖体相对于投影装置主体的位置信息。
在本实施方式中，第二盖体相对于投影装置主体的位置信息为第二盖体与投影装置主体的指定部位之间的相对距离。指定部位可以为最接近第二盖体的内部结构件靠近第二盖体的一侧所在的平面。
进一步地，通过设置于第二盖体的距离传感器来获取第二盖体相对于投影 装置的位置信息。在本实施例中，距离传感器为红外传感器，红外传感器可以通过发射红外线，并根据接收到反射回来的红外线的时间，进而获取第二壳体与第二盖体与指定部位之间的距离。在其他实施方式中，距离传感器可以为声波传感器或霍尔传感器等能够测量两物体相对距离的传感器。可选地，距离传感器还可以为光学传感器或声波传感器等，通过发射光脉冲或声波，并根据接收到反射回来的光脉冲或声波的时间，进而获取第二壳体与指定部位之间的相对距离。
S103：根据位置信息，确定盖门组件的开启方案。
进一步地，根据获取到的位置信息中的相对距离与预设距离的比对结果确定盖门组件的开启方案。其中，预设距离是指出厂时设定第二盖体处于初始状态，第一盖体沿第一预设轨迹运动，且不受阻碍地运动至第二盖体和指定部位之间时，第二盖体与投影装置主体的指定部位之间的相对距离。在本实施例中，第二盖体处于初始状态是指第二盖体嵌入显露孔中的状态。第一预设轨迹是指第一盖体向下运动以及向后运动或向后运动，镜头从显露孔显露的运动过程。
具体地，当相对距离小于预设距离信息时，第一盖体沿第一预设轨迹运动会被第二盖体阻挡，所以在控制第一盖体沿第一预设轨迹运动的同时，需要控制第二盖体沿第二预设轨迹运动。因此，确定盖门组件的开启方案为，控制所述第一盖体沿第一预设轨迹运动，所述第二盖体沿第二预设轨迹运动。本实施例中，第二预设轨迹是指第二盖体先向上再向后运动的预设轨迹。在一些实施方式中，第二预设轨迹可以是指第二盖体向后运动的预设轨迹，因为第二盖体与第一盖体均为向后运动，此时第二盖体也不会阻挡第一盖体的运动。
当相对于距离大于等于预设距离信息时，此时第一盖体沿第一预设轨迹运动不会被第二盖体阻挡，也即控制第一盖体沿第一预设轨迹运动的时候，第二 盖体维持原状也不会阻挡第一盖体的运动。因此，确定盖门组件的开启方案为，控制所述第一盖体沿第一预设轨迹运动，所述第二盖体维持初始状态。
S104：根据开启方案，控制盖门组件开启。
当确定开启方案后，可以通过设于投影仪装置主体的控制模块控制盖门组件按照已经确定的开启方案开启。例如，若确定的开启方案为，第一盖体沿第一预设轨迹运动，第二盖体维持初始状态，那此时盖门组件按照第一盖体沿第一轨迹运动，第二盖体维持初始状态的方案开启，使镜头自显露孔显露。
本申请提供的盖门组件控制方法，通过距离传感器来获取第二盖体相对于投影装置主体的位置信息，并根据位置信息确定盖门组件的开启方案，控制盖门组件开启。该盖门组件控制方法，能够更为智能便捷地对盖门组件的开启进行控制，避免第一盖体因运动空间不足而开启卡壳或开启失败的现象产生。
以上，仅是本申请的具体实施例而已，并非对本申请作任何形式上的限制，虽然本申请已以较佳实施例揭示如上，然而并非用以限定本申请，任何本领域技术人员，在不脱离本申请技术方案范围内，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，但凡是未脱离本申请技术方案内容，依据本申请的技术实质对以上实施例所作的任何间接修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
