实施该发明的最佳实施例
本发明的最佳实施方式
[0047] 为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图 1〜14及 实施例, 对本发明进行进一步详细说明。 应当理解, 在下面的描述中阐述了很 多具体细节以便于充分理解本发明, 但是本发明还可以采用其他不同于在此描 述的其它方式来实施, 本领域技术人员可以在不违背本发明内涵的情况下做类 似应用, 下文所描述的各实施例仅仅用以解释本发明, 并不用于限制本发明。
[0048] 请结合参照图 1至 14, 本发明实施例提供的镜头调整模组 1000包括基座机构 100 , 以及沿垂直于基座机构 100的主体所在平面的垂直方向上、 相对于基座机构 10 0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, 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经过的第一连通孔 Kl、 第二连通孔 Κ2和第三连通孔 Κ3, 各连通孔为大致 同心。 一般的, 镜头 JT的主要结构一般包括一个筒形框架, 在框架中布置镜片 组, 并且在框架接收光的一侧设有入光镜片, 在筒体出射光的一侧设有出光镜 片。 第一调整机构 200层叠地设置在基座机构 100上, 第二调整机构 300层叠地设 置在第一调整机构 200上, 因此, 在相对于基座机构 100的层叠设置方向上, 也 可以理解为沿垂直于基座机构 100的基座主体 110 (以下将作进一步说明) 所在 平面的垂直方向上, 相对于基座机构 100由近及远地依次层叠设置的第一调整机 构 200和第二调整机构 300, 且第二调整机构 300与镜头 JT固定连接。 此外, 在其 他实施例中, 对于基座机构 100、 第一调整机构 200和第二调整机构 300依次层叠 的顺序, 也可以是, 沿垂直于基座机构 100的基座主体 110 (以下将作进一步说 明) 所在平面的垂直方向上, 相对于基座机构 100由近及远地依次层叠设置第二 调整机构 300和第一调整机构 200, 第二调整机构 300设置在第一调整机构 100上 , 且第二调整机构 300与镜头 JT固定连接。 因此, 对于本发明所关于依次的描述 , 旨在说明第一调整机构 200与基座机构 100为活动连接、 第二调整机构 300与第 一调整机构 200为活动连接的彼此连接关系, 并非限制三者在空间方位上的特定 位置关系。 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, 其中, 第一电动驱动机构 400与第一调整机构 200传动连接并在驱动第一调 整机构 200的过程中以带动第二调整机构 300, 从而使得与第二调整机构 300固定 连接的镜头 JT被驱动以沿第一方向移动。 第二电动驱动机构 500与第二调整机构 300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 1中坐标轴的箭头所示, 第一方 向包括竖直的 Y-和 Y+两方向, 第二方向包括水平的 X-和 X+两方向。 根据上述关 于层叠连接设置可以进一步了解到, 由于第二调整机构 300可相对运动地与第一 调整机构 200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 对固定在第二调整机构 300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 对固定在第二调整机构 300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。 由此可知, 本实施例的镜头调整模组不仅结构紧凑, 占用空间小, 且由于采用电动驱动结 构, 保证了对镜头 JT位置的调整具有高精度。
结合参照图 2和 3, 作为本实施例的镜头调整模组的一种具体实施方式, 基座机 构 100包括基座主体 110, 在基座主体 110上设有沿第一方向设置的两组第一支撑 部, 第一调整机构 200包括第一滑块 210、 由各组第一支撑部支撑并穿插于第一 滑块 210的第一滑杆 220和在第一滑块 210上沿第二方向设置的两组第二支撑部, 第二调整机构 300包括第二滑块 310和由各组第二支撑部所支撑并穿插于第二滑 块 310的第二滑杆 320, 第一滑块 210和第二滑块 310分别在第一滑杆 220和第二滑 杆 320的引导下移动。 通过第一滑杆 220与第一滑块 210、 第二滑杆 320与第二滑 块 310的滑动配合, 减少了相对运动的摩擦力, 使得第一滑块 210和第二滑块 310 的移动平稳、 可靠, 从而可以对镜头 JT在第一方向和第二方向的位置进行准确 调整。
对于上述的第一支撑部和第二支撑部, 例如可以是可调整其中心孔的孔径大小 并固定在基座主体和第一滑块上的孔套 (未图示) , 优选的, 孔套分别与基座 主体和第一滑块一体成型, 孔套具有带内螺纹的两支臂及在两支臂之间在中心 孔径向方向上的间隔口, 因此, 利用先将第一滑杆 220和第二滑杆 320的两端插 入对应的孔套, 再通过不断增加螺钉等螺纹件在两支臂的内螺纹中旋转圈数来 逐步调小孔套的孔径, 也就是减小间隔口在径向上的间距, 因此, 可以达到支 撑并固定第一滑杆 220和第二滑杆 320的目的, 且可调孔套可以适应多种不同外 径的第一滑杆和第二滑杆, 但该结构比较复杂, 加工成本较高。 上述的第一支 撑部和第二支撑部例如也可以是分别包括相互配合的卡箍和凹槽 (未图示) , 具体来说, 在基座主体和第一滑块上分别设置具有圆弧面的凹槽, 第一滑杆和 第二滑杆的两端的一部分圆周面与对应的凹槽的圆弧面贴合, 卡箍包括中部具 有用于与第一滑杆或第二滑杆的两端的另一部分圆周面贴合的圆弧面的两个伸 长臂, 各伸长臂和相配合的凹槽两侧上对应地设有螺纹孔, 通过螺钉等螺纹件 将伸长臂和凹槽的两侧上螺纹孔固定连接, 所以, 也可以起到支撑并固定第一 滑杆和第二滑杆的目的, 但装配工序较多。 为了获得结构相对简单, 装配效率 高的技术效果, 在本实施例中, 具体参照图 2、 4至 6, 第一调整机构 200和第二 调整机构 300均包括多个螺纹固定件 SF, 两组第一支撑部和两组第二支撑部分别 为两对第一凸台 120和两对第二凸台 230, 第一凸台 120和第二凸台 230具有倒梯 形面或弧形面, 本实施例中, 采用倒梯形面。 第一滑杆 220和第二滑杆 320均为 包括横截面为 D形的两自由端和两自由端之间的圆柱体的大致圆柱形杆, 其中, D形横截面由设置在自由端的缺口 221、 321所形成, 也就是, 对应于 D形横截面 , 各自由端包括弧面 222、 322和由缺口 221、 321所形成的压接面 223、 323, 上 述弧形面和弧面均优选为圆弧面。 在弧面 222、 322和压接面 223、 323之间设有 贯通孔 224、 324, 弧面 222、 322与第一凸台 120和第二凸台 230的倒梯形面相抵 , 比如为螺钉的各螺纹固定件 SF分别经贯通孔 224、 324穿过弧面 222、 322与第 一凸台 120和第二凸台 230上的比如内螺纹孔的螺纹固定孔 121、 231相连接, 各 螺钉的螺钉头与压接面 223、 323相抵压, 从而保证第一滑杆 220和第二滑杆 320 被第一凸台 120和第二凸台 230可靠地支撑并固定。
[0051] 结合参照图 2和 3, 本实施例中, 作为第一电动驱动机构 400和第二电动驱动机 构 500的一种可实施方式, 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, 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 31 0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 310产生沿各对应螺杆的轴线方向的移动。 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。
[0052] 进一步结合参照图 7和 8, 关于第一马达 410和第二马达 510的固定连接方式, 较 优的, 本实施例中, 第一电动驱动机构 400和第二电动驱动机构 500还分别包括 均为 L形的第一固定片 430和第二固定片 530, 也就是第一固定片 430和第二固定 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, 第一固定片 430的两个第一子固定片 431分别通过螺纹连接与基座主体 110和第一 马达 410固定连接, 两个第二子固定片 531分别通过螺纹连接与第一滑块 210和第 二马达 510固定连接, 更具体来说, 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分别与第一滑 块 210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 如为螺纹固定件 SF的螺纹件螺纹连接。 由上所述, 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。
[0053] 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 置的支座 130和与支座 130固定连接的盖板 133, 支座 130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 和支座 130上对应地设置一对螺纹孔, 从而将盖板 133与支座 130固定连接, 进而 盖板 133将轴套 132固定于幵槽 131中。
[0054] 结合参照图 3至 5, 镜头调整模组 1000的第一滑块 210进一步地包括第一突出部 2 11, 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二连通孔 K2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上对应幵设螺纹孔, 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 2 11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。 由上所述, 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。
[0055] 结合参照图 3至 6, 进一步的, 本实施例中, 作为第一滑杆 220和第二滑杆 320分 别穿插于第一滑块 210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 25 0套接于第一滑杆 220的外周, 第一突出部 211还包括位于第二连通孔 K2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 3 20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的引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 , 优选的, 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 330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 22 0和第一螺杆 420分别对第一滑块 210的弓 I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。
[0056] 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分别为具有第一连 通孔 Kl和第二连通孔 K2的大致矩形体板件, 第二滑块 310为具有第三连通孔 Κ3 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。
[0057] 结合参照图 4至 6, 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 31 0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。
[0058] 作为本实施例的进一步改进, 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的外周上基座主体 110第一滑块 210, 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。
[0059] 结合参照图 3、 7和 8, 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 420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 520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 31 0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精准 移动。
[0060] 结合参照图 1和 6, 为实现第二滑块 310与镜头 JT良好的可分离地固定, 较佳的 , 在第二滑块 310上沿第三连通孔 K3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 314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 210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 JT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。
[0061] 进一步结合参照图 8, 为了较好地实现第二滑块 310与镜头 JT的可分离地固定连 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 3 14A, 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 314 A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。
[0062] 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 JT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 3 16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。
[0063] 结合参照图 1、 9和 10, 本发明还提供了一种投影设备, 该投影设备包括镜头 JT 、 镜头连接架 600、 光机 (未图示) 以及上述任一实施例中的镜头调整模组, 镜 头 JT与镜头调整模组固定连接, 镜头连接架 600分别与基座机构 100和光机相连 接, 优选的, 镜头连接架 600设有供镜头 JT经过的第四连通孔 (未图示) , 镜头 连接架 600远离基座机构 100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 620, 一般的, 透光部 620包括透光镜片, 透光镜片密封地固 定在架板 610上, 需要说明的是, 镜头连接架可以是用于连接基座机构和光机的 独立部件, 也可以是光机所包括的部件, 例如镜头连接架与光机为一体结构。 由此, 投影设备中经光源、 光学透镜组等部件所产生的光束经过光机发出并经 过镜头连接架 600的透光部 620射入镜头 JT, 通过镜头调整模组调整镜头 JT的位 置, 从而可以使镜头 JT处于接收由透光部 620入射的光束的最佳位置, 保证镜头 J T投射的投影图像达到优良质量。
另外, 在以上任一镜头调整模组实施例的基础上, 还可以设置镜头微调装置, 作为本发明可选实施例, 具体请参照图 11至 14, 镜头微调装置 2000包括镜头连 接架 600和基座主体 110, 镜头连接架 600与基座主体 110为相对设置并可调活动 连接。 镜头连接架 600具有供镜头经过的连通孔。 镜头微调装置 2000还包括用于 调节镜头连接架 600和基座主体 110的相对位置的多个位置调节机构 700, 各位置 调节机构 700包括螺纹连接件 710、 螺纹调节件 720、 弹性件 730, 以及包括作为 优选实施方式的贯通镜头连接架 600的架板 610的第一连接孔 611和第二连接孔 61 2以及设置在基座主体 110上的第三连接孔 113, 第一连接孔 611和第三连接孔 113 成对设置, 第二连接孔 612和设置在基座主体 110上的抵接部相对设置, 该抵接 部可以是基座主体 110本身, 也可以是固定在基座主体 110上的抵接片, 还可以 是抵接块 115 (以下将作详细说明) , 基座主体 110本身、 抵接片和抵接块 115优 选采用铸铁、 不锈钢等耐磨材料制成。 其中, 第一连接孔 611包括过孔 611A, 该 过孔 611A优选为光孔, 且第一连接孔 611整体设为通孔。 第三连接孔 113设有螺 纹孔, 且第三连接孔 113为盲孔, 对于第三连接孔 113所设螺纹孔的具体实施方 式, 可以是在第三连接孔 113的内周壁上直接设置螺纹也可以是在第三连接孔 11 3中布置内周壁上设有置螺纹的孔套。 螺纹连接件 710包括螺纹杆和连接头, 螺 纹杆设有用于与螺纹孔螺纹连接的外螺纹, 螺纹杆穿过过孔 611A, 过孔 611A的 内径大于螺纹杆的外径。 该螺纹杆可以是整体设有外螺纹也可以是自由端设有 用于与螺纹孔相连接外螺纹而接近连接头的部分设为光杆。 在螺纹连接件 710的 连接头和镜头连接架 600之间设置弹性件 730, 并且弹性件 730套设在螺纹连接件 710的螺纹杆的外周, 弹性件 730被压缩以对镜头连接架 600施加接近基座主体 11 0的预紧力。 弹性件 730优选的采用弹簧, 因弹簧具有受不同作用力能灵敏地产 生相应弹性变形、 弹性变形量较大、 成本低廉等优势, 另外, 也可以采用圆柱 状的弹性硅胶、 弹性橡胶等, 对于弹性硅胶和弹性橡胶, 应采用可产生较大弹 性变形量的材料制成, 本实施例中, 弹性件 730设为弹簧。 第二连接孔 612为螺 纹孔, 螺纹调节件 720与第二连接孔 612螺纹连接, 并且螺纹调节件 720自由端与 抵接部相抵接, 螺纹调节件 720和弹性件 730共同作用以调节镜头连接架 600和基 座主体 110的相对间距, 顺便提及的是, 当镜头连接架和基座主体相接触吋, 两 者的间距为 0。 螺纹连接件 710和螺纹调节件 720具体可以采用螺柱、 螺钉等, 本 实施例中, 螺纹连接件 710和螺纹调节件 720均采用螺柱。 可以理解的是, 利用 螺纹连接件 710的螺纹杆与螺纹孔的螺纹连接实现了镜头连接架 600和基座主体 1 10的连接, 通过螺纹调节件 720和弹性件 730的共同作用, 使得在螺纹连接件 710 的螺纹杆与过孔 611A的相对位移的同吋, 镜头连接架 600和基座主体 110相对间 距产生改变, 从而实现了镜头连接架 600和基座主体 110相对位置的活动调节。 更详细来说, 在螺纹调节件 720的自由端与抵接部相抵接且镜头连接架 600与基 座主体 110具有一定相对间距的情况下, 当用户旋转螺纹调节件 720以使螺纹调 节件 720的螺纹杆旋入第二连接孔 612的长度被增加吋, 螺纹调节件 720的自由端 相对于该抵接部旋转的同吋, 螺纹调节件 720能够带动镜头连接架 600克服预紧 力而产生远离基座主体 110的位移, 弹性件 730被压缩的程度被进一步增加, 因 此, 增加了镜头连接架 600相对于基座主体 110的相对间距, 可参照得出的, 当 用户反方向旋转螺纹调节件 720以使螺纹调节件 720的螺纹杆旋入第二连接孔 612 的长度被减少吋, 螺纹调节件 720的自由端相对于该抵接部旋转的同吋, 镜头连 接架 600在弹性件施加的预紧力作用下而产生接近基座主体 110的位移, 弹性件 7 30被压缩的程度被相应减少, 因此, 减少了镜头连接架 600相对于基座主体 110 的相对间距, 因此, 由上所述, 达到了便捷地调整镜头相对于镜头连接架 600和 基座主体 110的位置、 使镜头处于接收例如经过镜头连接架 600的光束的最佳位 置的技术效果。 并且, 由于设置了多个位置调节机构 700, 因此, 可以灵活地选 择其中的一个或大于一个的位置调节机构 700中的螺纹调节件 720进行调节, 从 而可以获得充足的镜头调整自由度。 因此, 通过设置上述多个位置调节机构 700 , 基座主体 110与镜头连接架 600为可调活动连接, 既能够利用手动的调节方式 来调节基座主体 110与镜头连接架 600之间的相对位置, 来调节镜头 JT相对于镜 头连接架 600的位置的目的, 也能够利用上述第一电动驱动激光和第二电动驱动 机构来调节镜头 JT相对于基座主体 110的位置的目的, 从而用户可以根据实际需 要择一或同吋地选择电动驱动的方式和调节相对位置的方式来调整镜头位置, 例如, 一般来说, 可以选择电动驱动的方式来快捷实现镜头位置调整, 也可以 选择调节相对位置的方式来更微幅地调整镜头位置。 由此可见, 本发明可选实 施例的镜头调整模组可以满足镜头位置调整的不同需求, 使用灵活。
[0065] 参照以上描述, 作为一种可替代实施方式, 其与上述镜头微调装置的结构基本 相同, 区别在于, 第一连接孔和第二连接孔设置成贯通基座主体, 第三连接孔 设置在镜头连接架上, 抵接部设置在镜头连接架上并与第二连接孔相对设置, 也就是说, 在可替代实施方式中, 螺纹调节件调节基座主体相对于镜头连接架 的运动。
[0066] 根据以上关于优选实施方式和可替代实施方式的描述, 两者的区别主要在于, 在优选实施方式中, 螺纹调节件 720在面向基座主体 600的一侧被进行调节, 而 在可替代实施方式中, 螺纹调节件在与镜头连接架 600相背的一侧并面向基座主 体 110的一侧被进行调节, 以下对采用优选实施方式本发明镜头微调装置实施例 做进一步详细描述, 对于采用可替代实施方式的其他镜头微调装置实施例可以 参照得出, 在此不再赘述。
[0067] 结合参照图 11和 14, 优选的, 本实施例中, 抵接部包括设置在基座主体 110上 的第四连接孔 114, 第四连接孔 114和第二连接孔 612成对设置, 在每个第四连接 孔 114中均设置抵接块 115, 螺纹调节件 720的自由端与抵接块 115相抵接。 通过 如此设置, 由于抵接块 115具有很好耐磨特性, 从而为螺纹调节件 720的自由端 与抵接块 115良好抵接以及相对于抵接块 115良好地旋转提供了足够保证, 而且 抵接块 115被固定在第四连接孔 114中, 不易移位或脱落, 提升了可靠性。 此外 , 还可以在第二支架 110的表面上设置围绕第三连接孔 114第四连接孔 114的垫片 116, 该垫片 116可以用于辅助调节第一支架 600和第二支架 110的相对间距。
[0068] 结合参照图 11和 13, 进一步的, 第一连接孔 611为包括过孔 611A、 背对基座主 体 110的沉孔 611B和位于过孔 611 A和沉孔 611B之间的阶梯面 611C的阶梯孔, 在 螺纹连接件 710的位于阶梯面 611C和螺纹连接件 710的连接头之间的螺纹杆的外 周套设作为弹性件 730的弹簧。 可以理解的是, 当镜头连接架 600与基座主体 110 具有预设相对间距吋, 该相对间距还可以进一步被增加以加大该弹簧被进一步 压缩的压缩量。 另外, 禾 1」用沉孔 611B的外周围绕弹性件 730的一个自由端, 因此 , 可以很好地定位弹性件 730的一自由端, 并且连接头与弹性件 730的接触面与 阶梯面 611C较优地均设为平面, 因而弹性件 730受力均匀, 稳定性高。
[0069] 结合参照图 11至 14, 作为进一步的改进, 基座主体 110设为中空大致矩形体板 件, 在大致矩形体板件临近四个顶角的位置处及镜头连接架 600对应于四个顶角 的位置处各布置一个位置调节机构 700。 根据以上描述, 更具体来说, 一个位置 调节机构 700可以理解为包括在临近基座主体 110的一个顶角位置处设置的第三 连接孔 113和第四连接孔 114、 在镜头连接架 600对应于上述基座主体 110的一个 顶角的位置处设置的第一连接孔 611和第二连接孔 612、 以及与相应各孔配合的 螺纹连接件 710、 螺纹调节件 720和弹性件 730。 如此的话, 由于位置调节机构 70 0的数量设为四个, 当同吋同方向旋转调节各螺纹调节件 720且旋转圈数大致相 同吋, 则镜头连接架 600相对于基座主体 110基本上沿平行于各螺纹连接件 710的 轴向方向移动, 从而可以调节镜头在该轴向方向上的移动。 而当对各螺纹调节 件 720旋转的圈数或旋转的方向不同或者仅对部分的螺纹调节件 720进行旋转调 节吋, 则镜头连接架 600相对于基座主体 110可以产生沿平行于各螺纹连接件 710 的轴向方向的移动和以经过其中两个螺纹连接件 710的轴线的连线为中心线的转 动或者产生以经过其中两个螺纹连接件 710的轴线的连线为中心线的转动, 从而 可以实现以移动和转动相结合方式或者转动方式来调节镜头的位置, 因此, 实 现了多方位地调节镜头位置。 另外, 需要了解的是, 位置调节机构 700还可以根 据实际需要设为其他的个数。
[0070] 以上内容是结合具体的实施方式对本发明所作的进一步详细说明, 不能认定本 发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术人员 来说, 在不脱离本发明构思的前提下, 还可以做出若干简单推演或替换。 另外 , 各个实施例之间的技术方案可以相互结合, 但是必须是以本领域普通技术人 员能够实现为基础, 当技术方案的结合出现相互矛盾或无法实现吋应当认为这 种技术方案的结合不存在, 也不在本发明要求的保护范围之内。
