这样，在多个第一长圆孔3111的限位下，限定了第一移动承靠壳体311沿第一长圆孔3111的长度方向滑动，进而避免了第一移动承靠壳体311在滑动过程中在其他方向出现的晃动。
其中，为了便于第一移动承靠壳体311的滑动，连接件34上与第一长圆孔3111对应的位置具有第一凸块，从而通过多个第一长圆孔3111对应的多个第一凸块支撑起第一移动承靠壳体311，这样，第一移动承靠壳体311所受的外力只需要克服与多个第一凸块之间的摩擦力即可。
其中，第一固定件3112为沿自身轴向对第一移动承靠壳体311进行固定，且不干扰第一移动承靠壳体311沿第一长圆孔3111的长度方向移动的固定件。第一固定件3112可以为螺钉，当然也可以为其他类型的固定件，本申请实施例对此不做限定。示例地，第一固定件3112为轴肩螺钉。
其中，第一固定件3112的数量可以为两个或两个以上，以便于使第一移动承靠壳体311更加稳定得支撑在连接件34。
示例地，当第一长圆孔3111的数量为两个时，两个第一长圆孔3111的长度方向不重合，且两个第一长圆孔3111位于第一移动承靠壳体311的两个对角处，进而通过两个第一长圆孔3111构成的对角线，实现了连接件34对第一移动承靠壳体311的稳定支撑。当第一长圆孔3111的数量为三个时，三个第一长圆孔3111为三角形的三个顶点，进而通过三个第一长圆孔3111构成的面，实现了连接件34对第一移动承靠壳体311的稳定支撑。当第一导向孔的数量为四个时，四个第一导向孔为矩形的四个顶点，进而通过四个第一长圆孔3111构成的面，实现了连接件34对第一移动承靠壳体311的稳定支撑。
需要说明的是，当镜头3不包括连接件34时，也即是第一移动承靠壳体311直接连接在光机壳体的第二开口端时，每个第一固定件3112穿过对应的第一长圆孔3111与光机壳体的第二开口端固定连接。

需要说明的是，对于上述第一移动承靠壳体311具有第一长圆孔3111的两个实施例，如图6所示，第一移动承靠壳体311的至少一侧具有环绕第一长圆孔3111的第一润滑件3113。这样，在第一固定件3112穿过对应的第一长圆孔3111与连接件34固定时，第一固定件3112上远离连接件34的一端与第一移动承靠壳体311之间，和/或第一移动承靠壳体311与连接件34之间具有第一润滑件3113，进而在第一移动承靠壳体311滑动时，可在第一润滑件3113的作用下减小第一移动承靠壳体311的摩擦阻力，便于增强第一移动承靠壳体311移动的顺畅性和灵活性，进而增加第一移动承靠壳体311的移动精度。
其中，第一润滑件3113为长圆孔结构，且第一润滑件3113的长度和孔径均大于第一长圆孔3111的长度和孔径，以便于第一润滑件3113环绕第一长圆孔3111。第一润滑件3113可通过粘接的方式固定在第一移动承靠壳体311的一侧，当然也可以通过其他方式固定在第一移动承靠壳体311的一侧，本申请实施例对此不作限定。
可选地，第一润滑件3113的材料为聚四氟乙烯。聚四氟乙烯摩擦系数低，且具有良好的自润滑作用，因而可以有效防止磨损，从而实现第一移动承靠壳体311滑动的顺畅性和灵活性。当然第一润滑件3113的材料也可以为其他材料，本申请实施例对此不作限定。

这样，第一电机3121接收第一控制指令，进而在启动后带动第一旋转件3122同步旋转。由于第一调节螺钉3123的一端沿第一旋转件3122的轴向与第一旋转件3122固定连 接，因而在第一旋转件3122旋转时，可以带动第一调节螺钉3123同步旋转。这样，第一调节螺钉3123旋转时，与第一调节螺钉3123螺纹连接的第一移动承靠壳体311沿第一调节螺钉3123的长度方向移动，从而实现第一移动承靠壳体311滑动，也即是实现镜筒32在第一方向上的调整。
可选地，如图5所示，连接件34上具有第一固定支架343和第一限位槽344；第一电机3121固定在第一固定支架343上，第一旋转件3122可旋转的支撑在第一限位槽344内，且第一限位槽344沿第一旋转件3122的轴向对第一旋转件3122进行限位。这样，第一固定支架343可以对第一电机3121进行固定支撑，第一限位槽344可以避免第一旋转件3122沿轴向的晃动。
其中，第一电机3121的输出轴的轴向与第一调节螺钉3123的长度方向垂直或者平行。第一电机3121可以通过螺钉固定在第一固定支架343上，当然也可以通过其他方式固定在第一固定支架343上，本申请实施例对此不作限定。第一限位槽344上设置有旋转轴，第一旋转件3122固定在该旋转轴上，且该旋转轴上设置有凸起和挡圈，以将第一旋转件3122限位在凸起和挡圈之间，实现对第一旋转件3122的轴向限位。当然，第一限位槽344也可以设置成其他结构，只要可以对第一旋转件3122进行限位即可，本申请实施例对此不作限定。
其中，第一电机3121与控制器电连接，以便于在接收到控制器传输的第一控制指令时，控制第一电机3121在第一时刻启动，并在第二时刻停止，从而保证第一电机3121通过第一旋转件3122和第一调节螺钉3123驱动第一移动承靠壳体311移动的距离为设定的移动距离，保证了第一移动承靠壳体311的移动精度。第一电机3121为减速电机或其他电机，本申请实施例对此不做限定。
可选地，当第一电机3121的输出轴的轴向与第一调节螺钉3123的长度方向垂直时，第一旋转件3122为带有涡轮的齿轮组；当第一电机3121的输出轴的轴向与第一调节螺钉3123的长度方向平行时，第一旋转件3122为直齿轮组。
示例地，当第一旋转件3122为直齿轮组件时，第一旋转件3122包括第一齿轮和第二齿轮，第一齿轮和第二齿轮互相啮合。第一齿轮沿轴向与第一电机3121的输出轴固定连接，第二齿轮可旋转的限位在连接件34上，第二齿轮沿轴向与第一调节螺钉3123的一端固定连接，这样，在第一电机3121启动后带动第一齿轮旋转，之后带动第二齿轮同步旋转，进而带动第一调节螺钉3123同步旋转。当然，第一旋转件3122也可以为带传动组件或其他类型的传动组件，只要可以将第一电机3121输出的动力传递给第一调节螺钉3123，以使第一调节螺钉3123在原地旋转即可，本申请实施例对此不做限定。
其中，第一调节螺钉3123的长度方向与第一移动导杆313的长度方向或第一长圆孔3111的长度方向平行。结合上述第一旋转件3122的结构，第一调节螺钉3123的数量为一 个。当然，在另一些实施例中，第一调节螺钉3123的数量为两个，此时两个第一调节螺钉3123的螺纹旋向相反。继续上述第一旋转件3122的结构，第一旋转件3122还包括第三齿轮，第三齿轮可旋转的纤维在连接件34上，且与第一齿轮啮合，另一个第一调节螺钉3123的一端与第三齿轮沿轴向固定连接。这样，通过两个第一调节螺钉3123带动第一移动承靠壳体311移动，能够进一步保证第一移动承靠壳体311移动的稳定性。
在一些实施例中，如图6所示，第一控制组件312还包括第一弹性件3124，第一弹性件3124套在第一调节螺钉3123上，且第一弹性件3124的两端分别与第一旋转件3122和第一移动承靠壳体311抵接。这样，第一弹性件3124可以在第一移动承靠壳体311移动时对第一移动承靠壳体311进行缓冲，从而可以进一步保证第一控制组件312对第一移动承靠壳体311的调节精度，避免第一移动承靠壳体311的突然移位。
在一些实施例中，第一移动组件31还包括第一感应器；第一感应器固定在连接件34上，且位于第一移动承靠壳体311的移动方向上，第一感应器用于检测第一移动承靠壳体311的移动距离，且当移动距离等于第一距离阈值时发送第一控制信号至第一控制组件312，以控制第一移动承靠壳体311停止移动。
其中，第一距离阈值为事先设定的第一移动承靠壳体311能够移动的最大距离值。这样，可以更加精确地控制第一移动承靠壳体311的移动距离，由于第一感应器能够控制第一移动承靠壳体311及时停止，因而可以避免第一移动承靠壳体311在移动至最大距离后继续移动，导致第一电机3121烧坏等不良后果。
另外，第一感应器也可以检测第一移动承靠壳体311与第一感应器之间的距离，当检测的距离小于第二距离阈值时，则表明第一移动承靠壳体311可能与第一感应器发生碰撞等，此时第一感应器可以发送第一控制信号至第一控制组件312，以控制第一移动承靠壳体311停止移动。其中，第二距离阈值指第一移动承靠壳体311与第一感应器之间的最小安全距离。
其中，连接件34上具有第二凹槽，进而可以将第一感应器固定在第二凹槽内，相应地，第一移动承靠壳体311上具有与第二凹槽对应的第二凸台，这样，在第二凸台移动的过程中伸入第二凹槽内时，第二凹槽内的第一感应器可以感应到第二凸台，以便于检测第二凸台的移动距离，也即是检测第一移动承靠壳体311的移动距离。第一感应器可以是距离传感器，比如红外线传感器或其他传感器等。
本申请实施例中，如图2所示，镜筒32直接固定在第一移动承靠壳体311上，此时在第一移动承靠壳体311的带动下，镜筒32只能沿第一方向移动，也即是只能在第一方向上调整镜头3的投影区域。
其中，镜筒32可通过多种连接方式与第一移动承靠壳体311固定连接。示例地，镜筒32通过固定螺钉与第一移动承靠壳体311固定连接。
当然，为了增大投影区域的调整范围，本申请实施例中，如图7所示，镜头3还包括第二移动组件33，第二移动组件33包括第二移动承靠壳体331和第二控制组件332；第二移动承靠壳体331可滑动的连接在第一移动承靠壳体311上远离光机系统2的一侧，第二控制组件332固定在第一移动承靠壳体311上，且与第二移动承靠壳体331传动连接，第二控制组件332用于接收第二控制指令，以驱动第二移动承靠壳体331沿第二方向移动；镜筒32与第二移动承靠壳体331固定连接，第二移动承靠壳体331具有第二透光孔，镜筒32用于接收穿过第二透光孔的调制光束并进行成像。
其中，第一方向与第二方向不平行。示例地，第一方向与第二方向垂直。可选地，第一方向为水平方向，也即是第一方向为左右方向，第二方向为竖直方向，也即是第二方向为上下方向。镜筒32与第二移动承靠壳体331之间的连接方式可参考上述描述的镜筒32与第一移动承靠壳体311之间的连接方式。
这样，由于第二控制组件332可以接收第二控制指令，以驱动第二移动承靠壳体331沿第二方向移动，因而能够实现第二移动承靠壳体331移动的自动控制，以保证第二移动承靠壳体331的移动量和移动精度，进一步地可以保证与第二移动承靠壳体331连接的镜筒32的移动量和移动精度。
接下来对第二移动承靠壳体331的结构和第二控制组件332的结构进行介绍。

其中，为了实现第二移动承靠壳体331的可滑动，在一些实施例中，如图8所示，第二移动组件33还包括多个第二移动导杆333，多个第二移动导杆333相互平行的固定在第一移动承靠壳体311上，第二移动承靠壳体331可滑动的套在多个第二移动导杆333上。
这样，通过多个第二移动导杆333限定了第二移动承靠壳体331只能沿第二移动导杆333的长度方向滑动，进而避免了第二移动承靠壳体331在滑动过程中在其他方向出现的晃动。
可选地，第二移动导杆333的长度方向与第一移动导杆313的长度方向垂直，以保证第一方向和第二方向垂直。这样可以基于标准的直角坐标系对镜筒32的位置进行调节。当然，第二移动导杆333的长度方向与第一移动导杆313的长度方向也可以成一定夹角，本申请实施例对此不做限定。
可选地，如图9所示，第一移动承靠壳体311上远离连接件34的一侧具有多对第三凸 台3114，多对第三凸台3114与多个第二移动导杆333一一对应，每个第三凸台3114上远离连接件34的一端具有第三凹槽3115，每个第二移动导杆333的两端分别固定在对应的一对第三凸台3114上的第三凹槽3115内。这样，将第二移动导杆333的端部压紧固定在第三凹槽3115内，从而能够保证第二移动导杆333的安装精度，进而可以保证第二移动承靠壳体331沿第二导向杆的移动方向的准确性。
其中，第二移动导杆333的端部焊接在第三凸台3114上的第三凹槽3115内。当然，第三凸台3114上可以加工贯穿第三凹槽3115的螺纹孔，这样可以通过压紧螺钉将第二移动导杆333的端部压紧在第三凹槽3115内。当然，第二移动导杆333的端部也可以通过其他方式固定在第三凹槽3115内，本申请实施例对此不作限定。
可选地，第二移动承靠壳体331的一对侧壁具有惯穿孔，多个第二移动导杆333可滑动的穿过惯穿孔，从而保证第二移动承靠壳体331在第二移动导杆333上的可滑动。或者，如图8所示，第二移动承靠壳体331的侧边具有多组第二套环3313，多组第二套环3313与多个第二移动导杆333一一对应，且每组第二套环3313套在对应的第二移动导杆333上，从而实现第二移动承靠壳体331沿第二移动导杆333的可滑动。或者，第二移动承靠壳体331上靠近第一移动承靠壳体311的一侧沿厚度方向具有与第一移动导杆313对应的凹槽，第一移动导杆313可以位于对应的凹槽，且能够在对应的凹槽内沿第二移动导杆333的长度方向移动。其中，在确保第二移动承靠壳体331的可滑动时，可通过上述三种方式中的至少一种实现，本申请实施例对此不做限定。

这样，在多个第二长圆孔3311的限位下，限定了第二移动承靠壳体331沿第二长圆孔3311的长度方向滑动，进而避免了第二移动承靠壳体331在滑动过程中在其他方向出现的晃动。
其中，为了便于第二移动承靠壳体331的滑动，连接件34上与第二长圆孔3311对应的位置具有第二凸块，从而通过多个第二长圆孔3311对应的多个第二凸块支撑起第二移动承靠壳体331，这样，第二移动承靠壳体331所受的外力只需要克服与多个第二凸块之间的摩擦力即可。
其中，第二固定件3312为沿自身轴向对第二移动承靠壳体331进行固定，且不干扰第二移动承靠壳体331沿第二长圆孔3311的长度方向移动的固定件。第二固定件3312可以为螺钉，当然也可以为其他类型的固定件，本申请实施例对此不做限定。示例地，第二固定件3312为轴肩螺钉。
其中，第二固定件3312的数量可以为两个或两个以上，以便于使第二移动承靠壳体 331更加稳定得支撑在连接件34。
示例地，当第二长圆孔3311的数量为两个时，两个第二长圆孔3311的长度方向不重合，且两个第二长圆孔3311位于第二移动承靠壳体331的两个对角处，进而通过两个第二长圆孔3311构成的对角线，实现了第一移动承靠壳体311对第二移动承靠壳体331的稳定支撑。当第二长圆孔3311的数量为三个时，三个第二长圆孔3311为三角形的三个顶点，进而通过三个第二长圆孔3311构成的面，，实现了第一移动承靠壳体311对第二移动承靠壳体331的稳定支撑。当第二导向孔的数量为四个时，四个第二导向孔可以组成矩形的四个顶点，进而通过四个第二长圆孔3311构成的面，实现了第一移动承靠壳体311对第二移动承靠壳体331的稳定支撑。
在又一些实施例中，第二移动组件33还包括第二移动导杆333和多个第二固定件3312，第二移动承靠壳体331具有与多个第二固定件3312一一对应的多个第二长圆孔3311；第二移动导杆333固定在第一移动承靠壳体311上，第二移动承靠壳体331可滑动的套在第二移动导杆333上，且多个第二长圆孔3311的长度方向均与第二移动导杆333的长度方向平行，第二固定件3312穿过对应的第二长圆孔3311与第一移动承靠壳体311固定连接。
其中，第二移动导杆333的设置和第二长圆孔3311的设置均可参考上述两个实施例，本申请实施例对此不在赘述。
需要说明的是，对于上述第二移动承靠壳体331具有第二长圆孔3311的两个实施例，如图10所示，第二移动承靠壳体331的至少一侧均具有环绕第二长圆孔3311的第二润滑件3314。这样，在第二固定件3312穿过对应的第二长圆孔3311与连接件34固定时，第二固定件3312上远离连接件34的一端与第二移动承靠壳体331之间，和/或第二移动承靠壳体331与第一移动承靠壳体311之间具有第二润滑件3314，进而在第二移动承靠壳体331滑动时，可在第二润滑件3314的作用下减小第二移动承靠壳体331的摩擦阻力，便于增强第二移动承靠壳体331移动的顺畅性和灵活性，进而增加第二移动承靠壳体331的移动精度。
其中，第二润滑件3314为长圆孔结构，且第二润滑件3314的长度和孔径均大于第二长圆孔3311的长度和孔径，以便于第二润滑件3314环绕第二长圆孔3311。第二润滑件3314可通过粘接的方式固定在第二移动承靠壳体331的一侧，当然也可以通过其他方式将第二润滑件3314固定在第二移动承靠壳体331的一侧，本申请实施例对此不作限定。
可选地，第二润滑件3314的材料为聚四氟乙烯。聚四氟乙烯摩擦系数低，且具有良好的自润滑作用，因而可以有效防止磨损，从而实现第二移动承靠壳体331滑动的顺畅性和灵活性。当然第二润滑件3314的材料也可以为其他材料，本申请实施例对此不作限定。
本申请实施例中，第二控制组件332的结构与第一控制组件312的结构相同或相似，示例地，第二控制组件332为旋转结构，此时如图8或图10所示，第二控制组件332包 括第二电机3321、第二旋转件3322和第二调节螺钉3323；第二电机3321与第一移动承靠壳体311固定连接，第二旋转件3322可转动的限位在第一移动承靠壳体311上，第二旋转件3322与第二电机3321的输出轴传动连接；第二调节螺钉3323的一端沿第二旋转件3322的轴向与第二旋转件3322固定连接，第二调节螺钉3323的另一端与第二移动承靠壳体331螺纹连接。
这样，第二电机3321可以接收第二控制指令，进而在启动后带动第二旋转件3322同步旋转。由于第二调节螺钉3323的一端沿第二旋转件3322的轴向与第二旋转件3322固定连接，因而在第二旋转件3322旋转时，可以带动第二调节螺钉3323同步旋转。这样，第二调节螺钉3323旋转时，与第二调节螺钉3323螺纹连接的第二移动承靠壳体331沿第二调节螺钉3323的长度方向移动，从而实现第二移动承靠壳体331滑动，也即是实现镜筒32在第二方向上的调整。
其中，第二电机3321、第二旋转件3322的固定方式，第二旋转件3322的结构，以及第二调节螺钉3323的数量均与上述实施例所述的第一电机3121、第一旋转件3122的固定方式，第一旋转件3122的结构，以及第一调节螺钉3123的数量相同或相似，本申请实施例对此不在赘述。
在一些实施例中，如图8或图10所示，第一控制组件312还包括第二弹性件3324，第二弹性件3324套在第二调节螺钉3323上，且第二弹性件3324的两端分别与第二旋转件3322和第二移动承靠壳体331抵接。这样，第二弹性件3324可以在第二移动承靠壳体331移动时对第二移动承靠壳体331进行缓冲，从而可以进一步保证第二控制组件332对第二移动承靠壳体331的调节精度，避免第二移动承靠壳体331的突然移位。
在一些实施例中，第二移动组件33还包括第二感应器；第二感应器固定在第一移动承靠壳体311上，且位于第二移动承靠壳体331的移动方向上，第二感应器用于检测第二移动承靠壳体331的移动距离，且当移动距离等于第三距离阈值时发送第二控制信号至第二电机3321，以控制第二电机3321停止，进而控制第二移动承靠壳体331停止移动。
其中，第二感应器的固定方式和工作原理均可参考上述实施例所述的第一感应器的固定方式和工作原理，本申请实施例对此不在赘述。
接下来，结合上述所述的第一移动组件31和第二移动组件33对镜筒32的移动位置进行解释说明。
如图11所示，镜头3包括第一移动组件31和第二移动组件33，第一移动组件31驱动镜筒32在左右方向移动，第二移动组件33驱动镜筒32在上下方向移动，从而在第一移动组件31和第二移动组件33的共同作用下，可实现镜筒32在二维平面内的移动。
其中，上述实施例所述的第一移动组件31包括的第一移动承靠壳体311的滑动方式与上述实施例所述的第二移动组件33包括的第二移动承靠壳体331的滑动方式可任意组合。
示例地，如图11所示，第一移动组件31包括的第一移动承靠壳体311具有第一长圆孔3111，且第一长圆孔3111的方向为水平方向；第二移动组件33包括多个第二移动导杆333，且第二移动导杆333的长度方向为竖直方向。
其中，第一移动承靠壳体311的至少一侧具有环绕第一长圆孔3111的第一润滑件3113，以通过第一润滑件3113减小第一移动承靠壳体311滑动时的阻力；第二移动承靠壳体331滑动时，通过第二移动导杆333保证了第二移动承靠壳体331滑动的稳定性，避免了第二移动承靠壳体333出现摆动的现象。
第一种情况，当第一移动承靠壳体311沿水平方向移动时，由于第二移动承靠壳体331固定在第一移动承靠壳体311上，此时第一移动承靠壳体311、第二移动承靠壳体331和镜筒32共同沿水平方向移动。也即是，相较于图11，图12中的镜筒32在水平向左的方向上有一定移动距离。
第二种情况，当第二移动承靠壳体331沿竖直方向移动时，由于第一移动承靠壳体311固定不动，因而只有第二移动承靠壳体331和镜筒32一同沿着竖直方向移动。也即是，相较于图11，图13中的镜筒32在竖直向下的方向有一定移动距离。
第三种情况，当第一移动承靠壳体311沿水平方向移动，且第二移动承靠壳体331沿竖直方向移动时，第一移动承靠壳体311、第二移动承靠壳体331和镜筒32共同沿水平方向移动，之后第二移动承靠壳体331和镜筒32一同沿着竖直方向移动。也即是，相较于图11，图14中的镜筒32在水平向左的方向上和竖直向下的方向上均有一定移动距离。
本申请实施例中，第一控制组件在第一长圆孔和/或第一移动导杆的导向作用下驱动第一移动承靠壳体沿第一方向滑动，从而带动第二移动承靠壳体和镜筒沿第一方向同步移动，第二控制组件在第二长圆孔和/或第二移动导杆的导向作用下驱动第二移动承靠壳体沿第二方向滑动，从而带动镜筒沿第二方向同步移动，这样即可实现镜筒在第一方向和第二方向的移动过程的自动控制，以保证镜筒在第一方向和第二方向的移动量和移动精度，进而保证镜筒调整后镜头的投影区域调整至预设位置，从而提高了投影主机的投影效果。
以上所述仅为本申请实施例的说明性实施例，并不用以限制本申请实施例，凡在本申请实施例的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请实施例的保护范围之内。
