[0052] 镜头密封套实施例
[0053] 作为本发明的一个目的, 以下对本发明所提供的镜头密封套的实施例做出详细 说明, 具体请参照图 1至 3, 镜头密封套 700包括中空筒状套主体 710, 该套主体 7 10用于套设在镜头 JT的镜头镜筒 (具体可参考图 11, 以下将作更详细的说明) 的外周并供镜头镜筒通过, 需要了解的是, 一般的, 镜头 JT的主要结构一般包 括一个筒形镜头镜筒, 在镜头镜筒中布置镜片组, 并且在镜头镜筒接收光的一 侧设有入光镜片, 在镜头镜筒出射光的一侧设有出光镜片。 上述套主体 710包括 多个沿其轴向方向布置的褶皱部 711, 可知的是, 褶皱部 711较佳地套设在镜头 镜筒的外周并与镜头镜筒弹性紧密接触。 优选的, 套主体 710由硅胶、 橡胶等弹 性材料制成, 通过设置褶皱部 711, 提高了套主体 710的弹性变形量, 也可以增 强褶皱部 711与镜头镜筒外周紧密接触的箍紧力, 虽然镜头镜筒临近出射镜片的 一侧一般设有轴向密封结构, 但通过褶皱部 711与镜头镜筒外周的紧密接触能够 进一步防止外界杂物沿套主体 710的轴向方向经过褶皱部 711和镜头镜筒之间的 间隙进入镜头镜筒接收光的自由端一侧所处的入光空间 IR, 也就是上述入光镜 片 IL接收光一侧所处的入光空间, 有利于保持该入光空间 IR相对于入光空间 IR之 外是密封的。 需要说明的是, 本说明书中所述的外界杂物包括灰尘、 粉尘、 水 汽、 微颗粒等。 在套主体 710两端设有第一幵孔 712和第二幵孔 713, 该第一幵孔 712和第二幵孔 713的孔径设置成与镜头镜筒相适配。 镜头密封套 700还包括第一 连接部 720和第二连接部 730, 第一连接部 720和第二连接部 730分别包括至少部 分地围绕第一幵孔 712和第二幵孔 713并对应沿远离第一幵孔和第二幵孔的方向 延伸的第一突起 721和第二突起 731, 优选的, 第一突起 721和第二突起 731分别 沿平行于套主体 710的径向方向延伸, 也就是说, 在只设置分别自第一幵孔 712
和第二幵孔 713的一部分外周沿远离第一幵孔和第二幵孔的方向延伸的第一突起 721和第二突起 731, 这些突起起到固定第一连接部 720和第二连接部 730并密封 第一幵孔 712和第二幵孔 713的对应部分外周的作用的情况下, 第一幵孔 712和第 二幵孔 713的其它部分外周可以通过设置诸如海绵等密封件的方式进行密封, 但 是, 优选的是, 第一突起 721和第二突起 731均设置成整体地围绕第一幵孔 712和 第二幵孔 713, 也可以说, 第一突起 721与第一幵孔 712、 第二突起 731与第二幵 孔 713呈大致喇叭状, 这样的话, 第一突起 721和第二突起 731的结构简单且能实 现良好密封固定。 另外, 需要说明的是, 上述关于第一突起和第二突起沿远离 第一幵孔和第二幵孔的方向延伸, 可以理解为第一突起和第二突起的延伸方向 分别与第一幵孔和第二幵孔的各自中心线均成一定夹角, 为了使第一突起和第 二突起被稳固和密封地固定, 上述夹角优选是直角, 即此种情况下, 第一突起 和第二突起分别沿平行于套主体的径向方向延伸。 此外, 为了增加镜头密封套 的可靠性, 可以分别在褶皱部与第一突起之间和褶皱部与第二突之间设置连接 加强部, 连接加强部由比褶皱部的耐疲劳强度更强的材料制成。 在第一突起 721 和第二突起 731上分别设有第一连接孔 722和第二连接孔 732, 第一连接孔 722和 第二连接孔 732用于与相应套连接件配合以固定镜头密封套 700, 套连接件可以 采用螺钉、 螺柱等。 较优的是, 镜头密封套 700由硅胶、 橡胶等弹性材料一体成 型, 因而制作工艺简单, 节约成本。 由上所述, 当镜头密封套 700套设在镜头镜 筒的外周吋, 镜头密封套 700能够阻止外界杂物直接经由镜头镜筒外周进入上述 入光空间, 从而降低或杜绝入光空间中外界杂物的存在, 避免外界杂物对镜头 接收光束带来的不利影响。
作为第一突起 721的一种具体实施方式, 第一突起 721包括整体围绕第一幵孔 71 2的环片, 在环片上均匀设置有多个第一连接孔 722, 该环片优选为圆环片, 环 片的中心大致与第一幵孔 712的中心重合, 且多个第一连接孔 722在环片上均匀 设置, 可以为第一突起 721被穿过各第一连接孔 722的多个套连接件固定吋提供 均匀的作用力, 保证第一幵孔 712在其径向方向上被严格密封。 进一步的, 参照 图 1和 2, 第一突起 721包括多个沿第一幵孔 712外周间隔布置的扇形片, 多个扇 形片整体地近似于上述环片并整体围绕第一幵孔 712, 在各个扇形片上设置有至
少一个第一连接孔 722, 各相邻扇形片之间的间隙可以为各扇形片提供沿第一幵 孔 712径向方向的一定变形量, 可以降低第一突起 721的加工精度, 节约成本。 更具体的, 在本实施例中, 多个扇形片被设置成各具有两个相对设置的第一连 接孔 722的第一扇形片 723和各具有四个第一连接孔 722的两个相对设置的第二扇 形片 724, 并且各个第一连接孔 722以第一幵孔 712的中心为中心对称设置, 如此 的话, 可以依据第一扇形片 723和第二扇形片 724形状的不同, 方便第一突起 721 在被固定吋的定位。
[0055] 作为第二突起 731的一种具体实施方式, 第二突起 731包括整体围绕第二幵孔 71 3的突板 733, 在突板 733上设置有多个第二连接孔 732, 各第二连接孔 732优选的 均布在突板 733上, 突板 733背对套主体 710的第一侧面上设有至少一圈凸筋, 可 知的, 上述凸筋向着远离套主体 710的方向延伸。 这样的话, 当第二突起 731被 穿过各第一连接孔 722的多个套连接件固定吋, 该至少一圈凸筋可以与与第二突 起 731相接触的其他部件的表面相抵接以密封第二突起 731和该表面的间隙。
[0056] 结合参照图 2和 3, 较优的, 凸筋包括在第一侧面的外边缘处设置的两圈第一凸 筋 734, 优选的是, 该两圈第一凸筋 734是等间距间隔的, 凸筋还包括一圈相较 于第一凸筋 734更接近第二幵孔 713的第二凸筋 735, 优选的是, 第二凸筋 735与 与其最接近的第一凸筋 734是变间距间隔的, 由此, 当第二突起 731被固定后, 相对于镜头密封套 700外部的外界杂物, 在第二幵孔 713的径向方向上, 两圈第 一凸筋 734提供了一重密封作用, 而第二凸筋 735提供了又一重密封作用, 可以 防止外界杂物进入第二幵孔 713。 另外, 第一凸筋 734和第二凸筋 735的形状设置 成不同的话, 可以在第一凸筋 734和第二凸筋 735之间形成不同大小的空间, 能 够对即使进入该空间的外界杂物产生不同气密阻力, 延缓外界杂物的运动。 此 夕卜, 凸筋的圈数还可以根据实际需要设置不同的数量。

[0060] 作为本发明的另一个目的, 以下对本发明所提供的镜头模组的实施例做出详细 说明。 镜头模组 (未图示) 一般应用于比如投影机的投影设备中被用来支撑及 固定镜头, 因此, 本发明对固定在镜头模组上的镜头尤其是镜头镜筒采取防外 界杂物措施, 具体来说, 镜头模组包括第一支座、 第二支座、 多个套连接件和 上述任一镜头密封套实施例中的镜头密封套, 关于镜头密封套的结构及优点, 具体请参照上文, 不再赘述, 相应的, 镜头模组也具有由镜头密封套的优点所 带来的优点。 第一支座和所述第二支座上分别设有与所述第一连接孔和所述第 二连接孔相对应的第三连接孔和第四连接孔, 所述多个套连接件连接对应的所 述第一连接孔和第三连接孔以及连接对应的所述第二连接孔和第四连接孔以将 所述第一突起和所述第二突起分别与所述第一支座和所述第二支座相连接, 该 多个套连接件可以采用螺钉、 螺柱等。 在本镜头模组实施例中, 第一支座和第 二支座的相对位置是固定的, 也就是镜头位置是不可调整的。 由上所述, 通过 上述套连接件及对应连接孔的配合, 镜头密封套被布置在第一支座和第二支座 之间, 从而当镜头被第一支座或 /和第二支座支撑并固定且镜头镜筒通过镜头密 封套吋, 位于第一支座和第二支座之间的镜头镜筒被镜头密封套所密封, 因此
, 存在于第一支座和第二支座之间空间的外界杂物不会附着在镜头镜筒外周以 及沿镜头镜筒外周运动至入光镜片上, 较优的是, 将第二支座的结构设置成其 与所述镜头镜筒的入光镜片之间可以形成一密封的入光空间, 或者设置另一与
第二支座相对并连接的第三支座, 第二突起被卡接在第二支座和第三支座之间 , 并且, 镜头镜筒的入光镜片与第三支座之间具有一密封的入光空间, 从而镜 头密封套能够防止外界杂物进入入光空间中, 入光镜片不会被外界杂物污染, 镜头能够良好地接收光束。
[0061] 镜头调整模组实施例
[0062] 作为本发明的另一个目的, 以下对本发明所提供的镜头调整模组的实施例做出 详细说明, 镜头调整模组与上述镜头模组的主要区别在于, 镜头调整模组可以 对安装于其上的镜头进行位置调整, 需要说明的是, 在一个其他实施例中, 镜 头调整模组包括相对设置的基座机构和第二调整机构, 该第二调整机构可以被 例如带螺纹调节杆机构的手动装置或例如马达与齿轮配合的电动装置的驱动机 构驱动以相对于基座主体移动, 从而带动与第二调整机构固定连接的镜头产生 位置改变, 上述各镜头密封套实施例的镜头密封套布置在基座机构和第二调整 机构之间, 起到对基座机构和第二调整机构之间空间的防外界杂物作用。 以下 , 在本实施例中, 以镜头调整模组包括基座机构、 第一调整机构和第二调整机 构为例来进行详细说明, 对于作为上述其他实施例中的镜头调整模组可以参照 理解和适应性改进, 总之, 它们都是利用本发明提供的镜头密封套 700的各优点 来提高镜头调整模组的防外界杂物性能, 提高镜头的出射光质量。 具体请结合 图 1至 3并参照图 4至 18, 镜头调整模组 1000包括基座机构 100, 以及沿射入镜头 J T的光束传输的方向上, 相对于基座机构 100由近及远地依次层叠连接设置的第 一调整机构 200和第二调整机构 300。 基座机构 100包括基座主体 110, 第一调整 机构 200包括第一滑块 210, 第二调整机构 300包括第二滑块 310, 且第二滑块 310 与镜头固定连接, 例如, 可以在第二滑块与镜头的镜头镜筒 TT上设置相对应的 卡接结构, 以实现两者的固定连接。 在基座机构 100、 第一调整机构 200和第二 调整机构 300的大致中心区域均设有一用于供镜头 JT的镜头镜筒 TT经过的第一连 通孔 113、 第二连通孔 216和第三连通孔 318, 各连通孔为大致同心, 镜头密封套 700的第一连接部 710和第二连接部 730分别固定在基座主体 110和第二滑块 310上 , 也就是, 经过第一连通孔 113的镜头 JT的镜头镜筒 TT通过穿过镜头密封套 700 而经过第二连通孔 216和第三连通孔 318 (以下将作详细说明) 。 作为第一滑块 2
10与基座主体 110、 第二滑块 310与第一滑块 210分别活动连接的具体实施方式, 镜头调整模组 1000还包括第一电动驱动机构 400和第二电动驱动机构 500, 第一 电动驱动机构 400包括例如利用联轴器来传动连接的第一马达 410和第一螺杆 420 , 第二电动驱动机构 500包括例如利用联轴器来传动连接的第二马达 510和第二 螺杆 520, 其中, 第一螺杆 420和第二螺杆 520分别与第一滑块 210和第二滑块 310 传动连接, 可知的是, 该传动连接方式是螺纹驱动连接, 即第一螺杆 420和第二 螺杆 520的螺纹部分分别与第一滑块 210和第二滑块 310上的螺纹部分相互配合, 该螺纹部分可以是直接形成在第一滑块 210和第二滑块 310的自身块体上或者设 置在分别固定于第一滑块 210和第二滑块 310之上的传动部件上。 另外, 上述采 用的螺杆也可以采用丝杆替代。 第一螺杆 420和第二螺杆 520分别在第一马达 410 和第二马达 510的驱动下旋转并通过该螺纹驱动连接使第一滑块 210和第二滑块 3 10产生沿各对应螺杆的轴线方向的移动。 即第一马达 410与第一滑块 210传动连 接并驱动第一调整机构 200以带动第二调整机构 300并驱动镜头 JT沿第一方向移 动。 第二马达 510与第二滑块 310传动连接并驱动第二调整机构 300以使第二调整 机构 300驱动镜头 JT沿与第一方向垂直的第二方向移动, 为便于理解, 根据图 4 中坐标轴的箭头所示, 第一方向包括 Y-和 Y+两方向, 第二方向包括 X-和 X+两方 向。 第一马达 410和第二马达 510可以同吋与基座主体 110和第一滑块 210中的一 个固定连接或者分别与基座主体 110和第一滑块 210固定连接。 根据上述关于层 叠连接设置可以了解到, 由于第二调整机构 300可相对运动地与第一调整机构 20 0活动连接, 因此, 第一电动驱动机构 400驱动第一调整机构 200相对于基座机构 100沿第一方向移动并带动第二调整机构 300随之移动从而间接实现对固定在第 二滑块 310上的镜头 JT在第一方向上的位置调整, 第二电动驱动机构 500驱动第 二调整机构 300相对于基座机构 100沿第二方向移动从而直接实现对固定在第二 滑块 310上的镜头 JT在第二方向上的位置调整, 从而可以实现对镜头 JT相对于基 座机构 100进行第一方向和第二方向的位置调整。
以下重点对镜头调整模组 1000所包括的镜头密封套 700及镜头调整模组 1000与 镜头密封套 700相配合的结构做出详细说明, 并请结合参照图 1和 2及以上对镜头 密封套 700实施例的相关描述。

[0065] 作为第一突起 721的一种具体实施方式, 第一突起 721包括整体围绕第一幵孔 71
2的环片, 在环片上均匀设置有多个第一连接孔 722, 第二滑块面向第一滑块的 一侧的环形面 350上对应于第一连接孔 722设置有第三连接孔 319, 这样可以为第 一突起 721被穿过各第一连接孔 722的多个套连接件 TL固定到第一滑块上吋的环 片与环形面 350紧密贴合提供均匀的作用力, 保证第一幵孔 712在其径向方向被 严格密封。 结合参照图 1、 6和 7, 优选的, 在本实施例中, 第一突起 721包括多 个沿第一幵孔 712外周间隔布置的扇形片, 多个扇形片作为一个整体围绕第一幵 孔 712, 多个扇形片被设置成各具有两个相对设置的第一连接孔 722的第一扇形 片 723和各具有四个第一连接孔 722的两个相对设置的第二扇形片 724, 并且各个 第一连接孔 722以第一幵孔 712的中心为中心对称设置, 因此, 不仅各相邻扇形 片之间的间隙可以为各扇形片提供沿第一幵孔 712径向方向的一定变形量, 降低 第一突起 721的加工精度, 可以依据第一扇形片 723和第二扇形片 724形状的不同 , 方便第一突起 721在被固定到第二滑块上吋的定位。 进一步的, 镜头调整模组 1000还包括多个与第一扇形片 723和第二扇形片 724的形状适配的垫片 360, 每个 垫片 360包括至少两个垫孔, 垫孔的数量与设置在第一扇形片 723和第二扇形片 7 24上的第一连接孔 722的数量相同, 各套连接件 TL穿过对应垫孔与各第一连接孔 722相连接, 这些垫片 360不仅可以避免各套连接件 TL直接施加作用力在第一扇 形片 723和第二扇形片 724上, 对第一扇形片 723和第二扇形片 724的损伤, 而且 , 由于各垫片 360具有较大的表面积, 因此, 可以通过各垫片 360对第一扇形片 7 23和第二扇形片 724分别与第一滑块相贴合的相对表面施加较大范围的作用力, 保证各扇形片与第一滑块的紧密贴合, 避免外界杂物从各扇形片与第一滑块之 间进入。

部件, 例如镜头转接架 600与光机为一体结构。 镜头转接架 600与基座主体 110相 连接, 例如, 可以通过螺钉连接镜头转接架 600与基座主体 110上对应螺纹孔对 的方式实现相连接。 镜头转接架 600包括架板 610, 架板 610面向基座主体 110的 架板侧部 611与凸筋相抵接。 这样的话, 在第二突起 731被穿过各第一连接孔 722 的多个套连接件 TL固定到基座主体 110之后, 再将镜头转接架 600固定连接到基 座主体 110, 第二突起 731夹持在基座主体 110和架板侧部 611之间, 从而该至少 一圈凸筋与架板侧部 611相抵接, 达到了密封第二突起 731和架板侧部 611之间间 隙的技术效果, 因此, 镜头的入光镜片 IL接收光一侧处在镜头转接架 600和基座 主体 110围成的密封的入光空间 IR中, 基本不受外界杂物的影响。
[0067] 进一步的, 镜头转接架 600包括由架板 610形成的并沿远离基座主体 110方向延 伸的容纳腔 620, 镜头镜筒 TT部分地容纳于容纳腔 620中, 在容纳腔 620上设有供 光束射入镜头的透光部 621, 透光部 621包括透光镜片, 透光镜片密封地固定在 架板 610上。 凸筋用于对容纳腔 620密封, 由此可知, 通过凸筋的作用, 位于基 座主体 110和镜头转接架 600之间的容纳腔 620为一密封空间, 镜头的入光镜片 IL 接收光一侧位于该容纳腔 620中, 入光镜片 IL可以在基本不受外界杂物影响的情 况下接收经透光部 621射入的光束, 保证镜头出射光及投影图像的质量优良。
[0068] 结合参照图 10至 13, 优选的, 架板侧部 611包括凸缘 611A和架接面 611B, 在基 座主体 110面向架板 610的基座主体面 110A上设有凹槽 115, 在突板 733面向套主 体 710的第二侧面的边缘设有至少一圈凸边 736, 凸缘 611A与基座主体面 110A相 抵接, 凸边 736插接于凹槽 115之中, 并且, 在本实施例中, 凸筋包括在突板 733 的第一侧面的外边缘处设置的两圈第一凸筋 734, 优选的是该两圈第一凸筋 734 是等间距间隔的, 凸筋还包括一圈相较于第一凸筋 734更接近第二幵孔 713的第 二凸筋 735, 优选的是第二凸筋 735与与其最接近的第一凸筋 734是变间距间隔的 , 第一凸筋 734和第二凸筋 735均与架接面 611B相抵接。 通过上述结构的设置, 在镜头转接架 600固定连接到基座主体 110吋, 通过凸缘 611A与基座主体面 110A 相抵接, 使得镜头转接架 600和基座主体 110之间基本不存在间隙或间隙很小; 通过凸边 736插接于凹槽 115之中, 可以提高第二突起 731被固定在基座主体 110 上的稳固性, 并且, 由于镜头转接架 600和基座主体 110之间的间隙对着突板 733
的处于凸边 736和两圈第一凸筋 734之间的部分, 凸边 736对从间隙进入的外界杂 物有一定的分流作用, 从而提高了镜头密封套 700的密封性能; 通过设置两圈第 一凸筋 734和一圈第二凸筋 735, 在镜头转接架 600和基座主体 110之间, 或者说 是第二幵孔 713的径向方向上, 共同提供了多重密封作用, 可以防止外界杂物经 突板 733和架板 610之间的间隙进入第二幵孔 713。
[0069] 进一步的, 各圈第一凸筋 734包括一对相对的第一直线段 (未标记) 和一对相 对的沿第二幵孔 713的径向方向远离第二幵孔 713的中心的弧形段 (未标记) , 第二凸筋 735包括分别与第一直线段平行的一对相对的第二直线段 (未标记) 和 一对相对的头肩段 735A, 各头肩段 735A包括两个肩段 735A2和位于其间的一个 头段 735A1 , 并且一对头肩段 735A的一对头段 735A1接近第二幵孔 713的外周, 该一对头段 735A1优选的是与第二幵孔 713的外周相切, 第二凸筋 735接近容纳腔 620的腔表面 622, 优选的, 第二凸筋 735与容纳腔 620的腔表面 622大致平齐。 因 此, 通过上述直线段、 弧形段和头肩段 735A的设置, 提高了第一凸筋 734和第二 凸筋 735的形状的不规则性, 能够增加它们的密封性能; 另外, 通过一对头段 73 5A1接近第二幵孔 713的外周以及第二凸筋 735接近容纳腔 620的腔表面 622的设置 , 可以使该一对头段 735A1更接近地在第二幵孔 713外周的附近以及第二凸筋 735 更接近地在腔表面 622的附近起到密封作用, 提高了第二凸筋 735的密封性能。

结合参照图 6、 17和 18, 下面对本实施例的镜头调整模组 1000做更详细的描述 , 第一马达 410和第二马达 510可以分别通过大致 L形的第一固定片 430和第二固 定片 530与基座主体 110和第一滑块 210固定连接, 具体来说, 大致 L形的第一固 定片 430和大致 L形的第二固定片 530均包括大致成直角设置的两个第一子固定片 431和两个第二子固定片 531, 两个第一子固定片 431分别与基座主体 110和第一 马达 410对应地幵设成对螺纹连接孔, 两个第二子固定片 531分别与突台和第二 马达 510对应地幵设成对螺纹连接孔, 各成对螺纹连接孔分别与例如作为螺纹固 定件 SF的螺钉螺纹连接。 由上, 利用 L形的第一固定片 430和第二固定片 530来固 定第一马达 410和第二马达 510, 使得第一马达 410和第二马达 510分别相对于基 座主体 110和第一滑块 210非直接接触地间接连接, 可以缓冲第一马达 410和第二 马达 510运行吋所产生的不可避免的振动, 从而避免基座主体 110和第一滑块 210 受振动影响而产生较大振动甚至位移所导致的镜头 JT产生不期望的位置变化的 不利情况发生, 另外, 由于各马达与其对应的螺杆的传动连接一般为刚性连接 , 通过设置 L形的第一固定片 430及第二固定片 530, 可以为各对应的马达与螺杆 提供一定的相对活动空间, 避免各马达与螺杆因过度相互作用所产生的过大扭 矩而带来的损坏, 提升了镜头调整模组的可靠性。
[0074] 结合参照图 6和 14, 为了牢固地固定第一螺杆 420, 作为进一步的改进, 基座机 构 100还包括一对用于固定第一螺杆 420两端的杆固定组件, 每个杆固定组件包 括基座主体 110上设置的支持座 130和与支持座 130固定连接的盖板 133, 支持座 1 30具有容纳轴套 132的幵槽 131, 第一螺杆 420的相对两端分别插接于轴套 132中 , 通过螺钉连接在盖板 133和支持座 130上对应地设置一对螺纹孔, 从而将盖板 1 33与支持座 130固定连接, 进而盖板 133将轴套 132固定于幵槽 131中。
[0075] 结合参照图 6、 14和 15, 镜头调整模组 1000的第一滑块 210进一步地包括第一突 出部 211, 第一突出部 211包括依次由第一滑块 210的第一侧面向远离第一连通孔 113并沿与第二方向平行的方向延伸的供第一螺杆 420穿过的第一通槽 212, 优选 的, 在第一突出部 211的自由端还可以设置用于与第二固定片 530固定连接的突 台, 在第一通槽 212中固定有与第一螺杆 420螺纹连接的第一传动块 240, 比如, 第一传动块和第一突出部对应幵设螺纹孔, 通过螺钉等螺纹件连接各螺纹孔以 将第一传动块固定在第一通槽中, 以保证其可靠传动。 第一传动块 240具体可以 为带内螺纹孔的柱状体, 例如第一传动块 240为活动螺母。 第一传动块 240和第 一螺杆 420的螺纹连接可以理解为内螺纹与外螺纹的配合, 在第一螺杆 420的旋 转过程中, 第一传动块 240的内螺纹会受到第一螺杆 420的外螺纹的作用力而沿 第一方向移动, 从而第一传动块 240与第一通槽 212在第一方向上相对的一对第 一槽表面中的其中一个相抵并通过对其中一个第一槽表面施力以驱动第一突出 部 211移动, 可知的是, 该第一传动块 240起到了上述传动部件的作用。 由上, 通过在第一滑块 210上设置第一传动块 240, 第一传动块 240与第一槽表面为面接 触, 因此, 第一传动块 240对第一槽表面的施力均匀, 从而第一滑块 210移动平 稳, 另外, 通过对第一螺杆 420旋转角度的控制, 可以精准地控制第一传动块 24 0进而第一滑块 210的移动距离。
[0076] 结合参照图 6、 14至 16, 作为第一滑杆 220和第二滑杆 320分别穿插于第一滑块 2 10和第二滑块 310的一种具体实施方式, 在第一滑块 210与第一侧面相对的第二 侧面上设有一对具有第一引导孔的.第一滑套 250, 第一滑套 250套接于第一滑杆 2 20的外周, 第一突出部 211还包括位于第三连通孔 216与第一通槽 212之间的、 供 第一滑杆 220穿过的通孔 213, 在第二滑块 310的周壁上设有相对设置的并具有第
二引导孔的两对第二滑套 330, 第二滑套 330套接于第二滑杆 320的外周。 可以得 知的是, 上述通孔 213类似的起到了第一滑套 250的作用, 由此, 第一滑块 210可 以通过第一滑套 250和通孔 213分别在一个第一滑杆 220的引导下沿平行于第一方 向移动, 第二滑块 310可以通过两对第二滑套 330分别在一个第二滑杆 320的弓 |导 下沿平行于第二方向移动, 于是, 通过对应的滑套和滑杆、 通孔和滑杆的配合 可以很大程度上减小滑套或通孔相对于滑杆移动的过程中的摩擦阻力, 保障第 一滑块 210和第二滑块 310的移动具有优良的平稳性。 另外, 在其他实施例中, 为了进一步减小摩擦阻力, 还可以在各第一滑套 250、 通孔 213和第二滑套 330中 均内设一个无油衬套 CT。 优选的, 第一滑套 250和第二滑套分别与第一滑块 210 和第二滑块 310—体成型, 从而可以简化结构, 降低成本。 此外, 通过设置具有 通孔 213和第一通槽 212的第一突出部 211, 既实现了第一滑杆 220和第一螺杆分 别对第一滑块 210的引导和驱动, 又确保了第一滑杆 220和第一螺杆 420的轴线具 有很高平行度, 从而使得第一滑块 210的移动平稳和准确, 还有利于镜头调整模 组的整体结构的紧凑。
[0077] 优选的, 第一滑杆 220和第二滑杆 320在基座主体 110的投影大致围成一方形, 该方形可以是长方形或正方形。 基座主体 110和第一滑块 210为分别具有第一连 通孔 113和第三连通孔 216的大致矩形体板件, 第二滑块 310为具有第四连通孔 31 8的大致圆柱体板件。 通过将基座主体 110和第一滑块 210设为大致矩形体板件大 致圆柱体板件, 可以便于两者的层叠设置, 并且, 通过第二滑块 310大致圆柱体 板件可以更好地与镜头 JT适配, 共同起到了减少镜头调整模组所占用空间的作 用。
[0078] 结合参照图 14至 16, 为了更准确地控制第一滑块 210和第一滑块 210的移动, 较 优的, 在基座主体 110和第一滑块 210上分别设有相配合的第一幵口 112和第一光 电传感器 260, 在第一滑块 210和第二滑块 310上分别设有相配合的第二幵口 215 和第二光电传感器 340, 可知的是, 各配合的幵口和光电传感器所设置的位置也 可以相应对调。 第一幵口 112沿第一方向延伸, 第二幵口 215沿第二方向延伸, 较佳的是, 第一幵口 112在第一方向的延伸距离设置成与第一滑块 210在第一方 向的预设移动距离相等, 第二幵口 215在第一方向的延伸距离设置成与第二滑块
310在第二方向的预设移动距离相等, 各光电传感器包括发光部和受光部, 各幵 口允许与其相配合的发光部所发出的检测光通过而被受光部接收, 具体来说, 镜头调整模组包括一控制器或者装配了镜头调整模组的投影设备包括一控制器 , 各光电传感器及各电动驱动机构分别与控制器电连接, 当第一滑块 210或\和第 二滑块 310将移动之吋及移动过程中, 相应光电传感器的发光部发出检测光, 若 相应光电传感器对应的受光部能够接收到检测光, 则控制器判断各滑块位于预 设移动距离之中, 控制器允许各电动驱动机构所包括的马达工作, 从而驱动第 一滑块 210或\和第二滑块 310进行移动, 而若相应光电传感器对应的受光部无法 接收到检测光, 则控制器判断各滑块即将位于预设移动距离之外, 控制器控制 马达停止工作, 保障第一滑块 210和第二滑块 310的移动均不超出预设移动距离 , 有助于可靠和精准地调整镜头 JT的位置。 此外, 优选的是, 若某一支架已意 外地位于预设移动距离之外吋, 控制器控制相应马达驱动该某一支架移动至其 预设移动距离之内, 比如其预设移动距离的二分之一处, 以保持该某一支架的 正常工作。
[0079] 进一步的, 第一幵口 112设置在基座主体 110的一侧面的第一突起 111上, 第二 幵口 215设置在一个第一滑套 250的第二突起 214上, 第一光电传感器 260固定在 第一滑块 210的第三侧面上, 第二光电传感器 340固定在第二滑块 310的外周上, 如此设置, 幵设各幵口和固定各光电传感器的结构基本上是利用一体成型的方 式所形成, 因此无需针对性地设置其他分体部件, 使得镜头调整模组的整体结 构紧凑, 占用空间小, 成本降低。
[0080] 结合参照图 6、 17和 18, 作为一可选的实施方式, 第二滑块 310包括例如沿远离 其外周延伸的第二突出部 311, 第二突出部 311中设有供第二螺杆 520穿过的第二 通槽 312, 第二通槽 312中固定有与第二螺杆 520螺纹连接的第二传动块 313, 比 如, 第二传动块和第二突出部对应幵设螺纹孔, 通过螺钉等螺纹件连接各螺纹 孔以将第二传动块固定在第二通槽中, 以保证其可靠传动。 第二传动块 313具体 可以为带内螺纹孔的柱状体, 例如第二传动块 313为活动螺母。 第二传动块 313 和第一螺杆的螺纹连接可以理解为内螺纹与外螺纹的配合, 在第二螺杆 520的旋 转过程中, 第二传动块 313的内螺纹会受到第二螺杆的外螺纹的作用力而沿第二
方向移动, 从而第二传动块 313与第二通槽 312在第二方向上相对的一对第二槽 表面中的其中一个相抵并通过对其中一个第二槽表面施力以驱动第二突出部 311 的移动, 可知的是, 该第二传动块 313起到了上述传动部件的作用。 由此可知, 通过在第二滑块 310上设置第二传动块 313, 第二传动块 313与第二槽表面为面接 触, 因此, 第二传动块 313对第二槽表面的施力均匀, 可使第二滑块 310平稳地 移动, 另外, 通过对第二螺杆 520旋转角度的控制, 可以精准地控制第二传动块 313的移动距离, 进而通过第二传动块 313的移动带动第二滑块 310移动
[0081] 结合参照图 4和 16, 为实现第二滑块 310与镜头 JT的良好固定, 较佳的, 在第二 滑块 310上沿第四连通孔 318的周向等间距地设有多个肋板 314, 在两两相邻的肋 板 314之间设有幵孔 315, 各幵孔 315在周向上等间距地幵设在两两相邻的肋板 31 4之间, 该多个幵孔 315供镜头 JT的框架外周设置的对应多个凸起 (未图示) 穿 过并旋转一定的角度, 使得多个肋板 314和多个凸起相互重合并卡合连接, 从而 通过肋板 314与凸起一一对应的过盈配合, 可以防止镜头 JT脱离第二滑块 310。 而当需要将镜头 JT与第二滑块 310分离吋, 可以将多个凸起反方向旋转以使多个 凸起与多个肋板 314完全错幵并与多个幵孔 315相对, 可知的是, 上述对镜头 JT 的凸起的旋转可以通过人工旋转镜头 JT的整体框架来实现。 因此, 当第一滑块 2 10沿第一方向移动吋, 第一滑块 210在移动过程中通过第一滑杆 220带动第二滑 块 310移动, 而第二滑块 310通过各肋板 314施加作用力于各凸起上从而驱动镜头 J T沿第一方向移动, 当第二滑块 310沿第二方向移动吋, 第二滑块 310通过各肋板 314施加作用力于各凸起上从而驱动镜头 JT沿第二方向移动。
[0082] 进一步结合参照图 18, 为了较好地实现第二滑块 310与镜头 JT的固定连接, 进 一步的, 在其中一个肋板 314的面向第一滑块 210的表面上设有限位凸块 314A, 限位凸块 314A在多个凸起的旋转方向上接近相邻的幵孔 315, 限位凸块 314A与其 中一个凸起的端面相抵靠。 通过第一滑块 210的限位凸块 314A与镜头 JT的凸起的 端面相抵靠, 可以指示镜头 JT的各凸起穿过各幵孔 315后是否旋转到位, 避免镜 头 JT的凸起的旋转角度过大或过小, 确保多个肋板 314和多个凸起相互良好地卡 接。
[0083] 为了更好地对第二滑块 310与镜头 JT固定连接, 进一步的, 第二滑块 310上设有
一卡扣机构, 卡扣机构包括拨片 316和卡钩 317, 卡钩 317用于与镜头设置的卡槽 相锁扣, 在其中一个肋板 314背向第一滑块 210的表面上幵设有一卡口, 拨片 316 与一扭簧相连并可弹性复位地带动卡钩 317进入或退出卡口以实现卡钩 317用于 与卡槽的锁扣或解锁, 因此, 在锁扣状态下, 镜头 JT与第二滑块 310被锁紧固定 , 只有在解锁的状态下, 镜头 JT的各凸起才可以被旋转以与多个幵孔 315相对并 被进一步抽离第二滑块 310。
[0084] 综上所述, 在镜头调整模组 1000利用包括第一调整机构 200和第二机构 300在内 的镜头位置调整结构实现了可靠和精准地调整镜头位置使得镜头处于镜头投影 至屏幕上的图像清晰度达到较佳的工作位置的同吋, 一方面, 镜头密封套 700防 止了由于外界杂物从镜头调整模组 1000所预留的用于镜头位移的间隙经过而将 对镜头的入光镜片 IL所造成的污染; 另一方面, 镜头密封套 700对基座本体 110和 镜头转接架 600之间的良好密封, 则保证了入光镜片 IL始终处于密封的入光空间 I R中, 因此, 镜头能够良好地接收光束, 从而出射高质量的投影图像。
[0085] 投影设备实施例
[0086] 作为本发明的再一个目的, 本发明还提供了一种投影设备, 该投影设备包括镜 头 JT、 光机以及上述任一镜头调整模组实施例中的镜头调整模组, 镜头 JT与第 二滑块 310固定连接, 镜头 JT的镜头镜筒 TT通过镜头密封套 700, 镜头转接架 600 分别与基座主体 110和光机相连接, 并且镜头转接架 600远离基座主体 110的架板 610上设置有用于将光机发出的光束透过并射入镜头 JT的透光部 621。 由此, 镜 头的入光镜片 IL接收光一侧处在镜头转接架 600和基座主体 110围成的密封的入光 空间 IR中, 因此, 当投影设备中由光机所包括的光源、 光学透镜组等部件作用 而产生的光束经过透光部 621射入镜头 JT的入光镜片 IL吋, 入光镜片 IL可以在基 本不受外界杂物影响的情况下接收该光束, 可以保证投影设备的镜头出射光及 投影图像的质量优良。
