本发明的最佳实施方式
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本实用新型。
如图 1 至 5 所示,根据本实用新型的实施例,反光镜调整装置包括固定安装座、活动连接结构 20 、第一调节结构 40 和第二调节结构 50 。其中,固定安装座用于承载反光镜组件 30 、第一调节结构 40 和第二调节结构 50 ;活动连接结构 20 将反光镜组件 30 连接至固定安装座,活动连接结构 20 具有第一轴线,活动连接结构 20 绕第二轴线可转动地设置在固定安装座上,第一轴线与第二轴线相互垂直,活动连接结构 20 用于连接反光镜组件 30 和固定安装座,使反光镜组件 30 能够绕第一轴线和第二轴线调整角度;第一调节结构 40 可移动地设置在安装背板 11 上,并驱动反光镜组件 30 绕第二轴线转动,第一调节结构 40 能够使反光镜组件 30 绕第一轴线转动,以独立调节反光镜组件 30 的角度,通过移动第一调节结构 40 可以使反光镜组件 30 的与第一调节结构 40 接触的位置相应移动,进而使反光镜组件 30 绕第二轴线转动;第二调节结构 50 可移动地设置在固定安装座上,并驱动反光镜组件 30 绕第一轴线转动,通过移动第二调节结构 50 可以使反光镜组件 30 的与第二调节结构 50 接触的位置相应移动,进而使得反光镜组件 30 绕第一轴线转动,实现对反光镜组件 30 的角度调整。第一调节结构 40 和第二调节结构 50 两者之间相互独立,单独调节,不会影响调节精度,且调节更加快速简单。
在本实施例中,固定安装座包括安装背板 11 ,反光镜组件 30 通过活动连接结构 20 连接至安装背板 11 ,安装背板 11 上设置有固定板 111 ,固定板 111 垂直于安装背板 11 延伸。活动连接结构 20 包括横板段 21 和竖板段 22 。横板段 21 通过第一锁紧结构 61 与固定板 111 连接,竖板段 22 垂直于横板段 21 ,且竖板段 22 与横板段 21 一体成型,竖板段 22 与横板段 21 的连接线为第一轴线,竖板段 22 与反光镜组件 30 连接。
在本实施例中,第一轴线为横向轴线,第二轴线为竖向轴线。活动连接结构 20 为弹性结构,也即为 L 型弹片。活动连接结构 20 可以为反光镜组件 30 提高弹性回复力,当反光镜组件 30 受驱沿一个方向绕第一轴线转动后,若需反向调节,则只需将第一调节结构 40 反向移动需要距离,之后活动连接结构 20 的回复力可以使反光镜组件 30 自动反向转动,这样更加方便快捷。
优选地,为了保证最优的调节效果,保证第二调节结构 50 在调节时不会造成反光镜组件 30 绕第二轴线旋转,第二调节结构 50 与反光镜组件 30 接触的第二接触位置处于活动连接结构 20 的第二轴线在反光镜组件 30 的投影线上。
需要说明的是,在本实施例中,第二轴线在反光镜组件 30 的投影线与第一轴线的中垂线重合。这样能够保证当第二调节结构 50 驱动反光镜组件 30 转动时,第二调节结构 50 施加在反光镜组件 30 上的力的作用点不会使反光镜组件 30 绕第二轴线转动,进而保证第二调节结构 50 和第一调节结构 40 能够互不干扰,进而保证调节精度。
优选地,为了保证最优的调节效果,防止在调整反光镜组件 30 绕第二轴线转动的角度时导致反光镜组件 30 绕第一轴线转动,以保证调整精确性,第一调节结构 40 的与反光镜组件 30 接触的第一接触位置处于活动连接结构 20 的第一轴线的延长线上,且位于第二轴线的一侧。第一调节结构 40 作用在反光镜组件 30 上的力的作用点位于第一轴线的延长线上保证了第一调节结构 40 施加在反光镜组件 30 上的力不会使反光镜组件 30 绕第一轴线转动,第一调节结构 40 作用在反光镜组件 30 上的力的作用点位于第二轴线的一侧保证第一调节结构 40 可以使反光镜组件 30 绕第二轴线转动,以保证调节的灵敏度,同时保证调节的精确性。
在本实施例中,第一调节结构 40 为水平独立调节结构,第二调节结构 50 为垂直独立调节结构。
在本实施例中,安装背板 11 上设置有第一螺纹孔和第二螺纹孔,第一调节结构 40 包括与第一螺纹孔配合的水平调节件,水平调节件具有与第一螺纹孔配合的螺纹杆,第二调节结构 50 包括与第二螺纹孔配合的垂直调节件,垂直调节件具有与第二螺纹孔配合的螺纹杆。水平调节件和垂直调节件均通过螺纹连接调节,调节精度高,结构简单,便于操作。 在本实施例中,固定板 111 上设置有固定孔,横板段 21 上设置有锁紧孔,第一锁紧结构 61 包括第一锁紧件,第一锁紧件穿过锁紧孔并与固定孔螺纹连接。通过第一锁紧件和锁紧孔的配合能给保证活动连接结构 20 与固定板 111 的有效固定,进而保证结构稳固可靠。
为了保证第一调节结构 40 能给实现调节,防止第一锁紧件将活动连接结构 20 锁紧后妨碍对反光镜组件的调节,第一锁紧件包括锁紧螺栓,锁紧孔的内周面与锁紧螺栓的外周面之间具有第一调节间隙,这样可以保证第一锁紧件不会干涉反光镜组件 30 转动,当反光镜组件 30 调节至合适角度后,可以将第一锁紧件拧紧,使其压紧横板段 21 ,防止活动连接结构 20 移动,保证调节精确性。通过第一调节结构 40 进行调节时,由于锁紧螺栓与锁紧孔之间具有间隙,因而可以调节活动连接结构 20 ,使其转动。
第二轴线为反光镜组件通过活动连接结构 20 连接至固定板 111 上后,在第一调节结构 40 的驱动下转动而形成的虚拟轴线。
优选地,为了提高调节精度,固定板 111 上设置有竖直轴 112 ,竖直轴 112 的轴线为竖向轴线,横板段 21 上设置有配合孔 211 ,配合孔 211 与竖直轴 112 配合。这样当活动连接结构 20 转动过程中,其绕着竖直轴 112 转动,调节的精度更高,也更加能够避免第一调节结构 40 和第二调节结构 50 之间的干扰。
在本实施例中,反光镜组件 30 包括活动支架 31 ,反光镜 32 固定设置在活动支架 31 上,活动连接结构 20 固定连接在活动支架 31 的远离反光镜 32 的侧面上。活动支架 31 作为安装载体承载反光镜 32 ,防止损坏反光镜 32 的结构。
根据本实用新型的另一方面,提供一种投影机,包括反光镜调整装置,反光镜调整装置为上述的反光镜调整装置。采用该反光镜调整装置的投影机能够单独对反光镜 32 的水平角度和垂直角度进行调节,不会发生干扰,调节精度好,调节简单方便。
从以上的描述中,可以看出,本实用新型上述的实施例实现了如下技术效果:反光镜粘接在活动支架上,通过活动连接结构连接预固定在安装座上,通过旋动第一调节结构,使反光镜绕第二轴线旋转,调好水平方向的角度,再锁紧活动连接结构;然后旋动第二调节结构,使反光镜绕第一轴线旋转,调好垂直方向的角度,最后点胶固定螺丝及反光镜。
通过上述过程将反光镜调整做到独立的二维调节而不相互影响,而且实现的操作空间较小,且第一轴线和第二轴线都在同一个活动连接结构上,结构更简单。
以上所述仅为本实用新型的优选实施例而已,并不用于限制本实用新型,对于本领域的技术人员来说,本实用新型可以有各种更改和变化。凡在本实用新型的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。
