4.本发明的光学成像装置可应用于交通工具, 其沿着挡风玻璃的弧面设置, 使光学 成像装置的中心线相对于使用者的直视的中心线倾斜, 有效避免光学成像装置的显示影 像发生失真的状况。
5.本发明的光学成像装置可依据用户的高度不同而利用角度调整机构调整光学成 像装置的透镜相对于挡风玻璃的角度, 进而让使用者观看完整的放大的显示影像。

10.本发明的光学成像装置具有光感测模块, 透过光感测模块感测太阳光照射至光
学成像模块的照射量, 若其超过门槛值, 则调整壳体的角度或覆盖遮光件于光学成像模 块的影像输出端, 以减少太阳光照射至光学成像模块的照射量或阻隔太阳光直接穿过透 镜组件照射至光学成像模块, 进而使光学成像模块的組件产生热损坏。 光感测模块可与 光学成像模块的壳体相连, 如此可随着壳体转动而带动光感测模块转动, 并自动地使光 感测模块的感测端与透镜組件朝向同一方向。
1 1 .本发明的光学成像装置使用至少两个透镜組件并排设置, 以缩短透镜組件的焦 距, 进而縮短光学成像装置的长度。

为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效, 以下结合附 图及较佳实施例, 对依据本发明提出的一种光学成像装置其具体实施方式、 结构、 特征 及其功效, 详细说明如后。
请参阅图 1及图 2, 其是本发明的第一实施例的光学成像装置的立体图及剖面图; 如图所示, 本实施例提供一种光学成像装置 1, 光学成像装置 1 包含壳体 10及光学成像 模块 11, 光学成像模块 11设置于壳体 10内。 本实施例的光学成像模块 11 包含显示组 件 110、 至少一个第一反射组件 111、 第二反射组件 112及透镜组件 113, 然本实施例的 第一反射組件 111的数量为一个,第一反射组件 111及第二反射组件 112分别为反射镜。
壳体 10具有开口 100、 底部 101及侧壁, 側壁包含第一侧壁 102a及相对于第一侧
壁 102a的第二侧壁 102b, 底部 101对应开口 100。 显示组件 110设置于侧壁的第一侧 壁 102a, 并位于壳体 10内。 第一反射组件 111设置于侧壁的第二侧壁 102b, 然第一反 射組件 111位于第一传递路径 S1上, 其中第一传递路径 S1指显示组件 110所显示的显 示影像 1101的传递路径。
第二反射组件 112设置于壳体 10的底部 101, 透镜组件 113嵌设于开口 100, 然第 二反射组件 112相对透镜组件 113倾斜一角度, 第二反射组件 112的宽度大于透镜組件 113的宽度, 并位于第二传递路径 S2上, 其中第二传递路径 S2指经第一反射组件 111 反射的显示影像 1101的传递路径。 透镜组件 113位于第三传递路径 S3上, 第三传递路 径 S3指经第二反射组件 112反射的显示影像 1101的传递路径,然上述第一传递路径 S1、 第二传递路径 S2及第三传递路径 S3的总长度小于透镜组件 113的焦距, 即使显示組件 110位于透镜組件 113的焦距内(如图 3所示), 透镜组件 113朝向外部的一侧为影像输 出端 1131。
请一并参阅图 3及图 4, 其为本发明的第一实施例的光学成像装置的成像示意图; 如图所示, 当用户 2从光学成像装置 1的外侧透过透镜組件 113观视显示組件 110所显 示的显示影像 1101 时, 因显示組件 110位于透镜组件 113的焦距 f 内, 因此使用者 2 可看到放大并等效位于远处的显示影像 1101, (虚像),而放大并等效位于远处的显示影 像 110Γ 与用户 2间的距离 D, 较佳实施例可以为大于 2米, 让用户 2观看远方对象 3 或景物, 可同时观看到放大并等效位于远处的显示影像 1101, , 而且放大并等效位于远 处的显示影像 1101, 的内容可为远方对象 3或景物的信息或其他参考信息,如此让用户 2不用改变其眼睛的焦距, 于观看远方对象 3或景物的同时可观看显示于放大并等效位 于远处的显示影像 1101, 的参考信息。
由图 3可知, 可知本实施例的光学成像装置 1若未设有第一反射组件 111及第二反 射組件 112时, 显示组件 110必须对应透镜组件 113设置, 如此显示組件 110至透镜組 件 113间的距离为第一传递路径 S1、 第二传递路径 S2及第三传递路径 S3的总长度,所 以透过第一反射组件 111及第二反射組件 112的设置,可使光学成像装置 1的体积缩小, 同时也表示增加反射组件的数量更能縮小光成像装置 1的体积。
于此更进一步提供一实施例, 此实施例是增加第一反射組件 111的数量, 请参阅图 5, 其为本发明的第二实施例的光学成像装置的剖面图; 如图所示, 本实施例的光学成 像装置 1具有两个第一反射組件 111, 一个第一反射组件 111 设置于设有显示组件 110 的第一侧壁 102a,并位于显示组件 110的下方, 另一个第一反射组件 111设置于第二侧 壁 102b,并与显示组件 110及位于显示组件 110下方的第一反射組件 111相对应。设置 于第二侧壁 102b的第一反射组件 111位于第一传递路径 S1上, 位于显示组件 110下方 的第一反射組件 111位于第四传递路径 S4上,第四传递路径 S4指设置于第二侧壁 102b 的第一反射组件 111所反射的显示影像 1101 的传递路径。 第二反射組件 112位于第五 传递路径 S5上, 第五传递路径 S5指位于显示組件 110下方的第一反射組件 111所反射 的显示影像 1101 的传递路径。 第四传递路径 S4及第五传递路径 S5的总长度相当于第 一实施例的光学成像装置 1 的第二传递路径 S2的长度, 也表示增加第一反射组件 111 的数量, 可将原本第二传递路径 S2由第四传递路径 S4及第五传递路径 S5所构成的弯 折路径替代, 以縮短第三传递路径 S3的长度, 进而縮短壳体 10的纵向长度, 最终达到 缩小光学成像装置 1的体积的目的。
不论第一实施例及第二实施例的光学成像装置 1,其第一传递路径 S1及第二传递路 径 S2 (第四传递路径 S4及第五传递路径 S5)并未相互交错,如此不会影响光学成像装置 1从影像输出端 1131输出的显示影像的显示质量。
下述以第二实施例的光学成像装置 1进行说明, 请一并参阅图 6、 图 7A及图 7B, 其为本发明的第二实施例的光学成像装置的成像示意图及透镜组件的示意图; 如图所
示, 为了让使用者 2的双眼 21 能同时看到完整的显示影像 1 10Γ , 本实施例的透镜組 件 1 13的宽度 W大于使用者的两眼的间距 d, 然一般使用者 2的两眼 21 的间距 d介于 60圍与 70mm之间, 所以透镜组件 1 13的宽度 W, 较佳实施例可以为大于 70mm。 然每一 眼 21透过透镜組件 1 13观视可产生观看区域 P1、 P2, 两眼 21 的观看区域 P1、 P2具有 重叠观看区域 R, 然光学成像装置 1所产生的显示影像 1 10Γ位于两眼 21透过透镜组件 1 13观视的重叠观视区域 R内, 如此用户 2的双眼 21 可同时观看到显示影像 1 10Γ 。 另外, 本实施例的透镜組件 1 13为矩形(如图 7A及图 7B所示), 如此有效縮小光学成像 装置 1的体积。 然, 上述透镜組件 1 13使用长焦距的透镜, 其中透镜组件 1 13可为单面 凸透镜、 双面凸透镜或菲涅尔透镜, 如此光学成像装置 1所产生的放大并等效位于远处 的显示影像 1 101, 的失真度较少, 而且使放大并等效位于远处的显示影像 1 101 '的焦距 较稳定。
再参阅图 5, 本实施例的壳体 10呈筒状, 即壳体 10的纵向长度大于其横向宽度, 其中壳体 10的纵向长度指底部 101 的最低点至开口 100的垂直距离, 壳体 10的横向宽 度指第一侧壁 102a与第二侧壁 102b间的水平距离, 因第一传递路径 S1、第二传递路径 S2 (第四传递路径 S4及第五传递路径 S5)及第三传递路径 S3的总长度必须小于透镜組 件 1 13的焦距, 也说明第一传递路径 S1的长度小于第三传递路径 S3的长度。
当然本实施例的壳体 10的形状可依据使用者需求而改变, 例如: 使壳体 10的纵向 长度小于其横向宽度, 如此第一传递路径 S1的长度大于第三传递路径 S3的长度。 不论 壳体 10的形状如何改变, 只要使显示组件 1 10位于透镜组件 1 13的焦距内即可产生放 大并等效位于远处的显示影像 1 10Γ (如图 6所示)。
请参阅图 8, 其为本发明的第二实施例的光学成像装置的使用状态图; 如图所示, 本实施例说明光学成像装置 1装设于汽车 4内的使用状态, 当本实施例的光学成像装置 1装设于汽车 4的仪表板座 41 内时, 透镜组件 1 13从仪表板座 41的表面露出, 并朝向 汽车 4的挡风玻璃 42。 依据仪表板座 41 内的空间及其他电子組件的配置, 较适合使用 纵向长度大于横向宽度的壳体 10,如此壳体 10呈筒状, 以避免占据仪表板座 41 内的空 间。 于此再次说明, 可依据设置位置的空间而改变壳体 10的形状, 不限于本实施例的 壳体 10的形状。
同时请参阅图 9A及图 9B, 其为本发明的第二实施例的光学成像装置相对于挡风玻 璃的示意图; 如图所示, 挡风玻璃 42具有弧面 421, 弧面 421具有曲率, 本实施例的光 学成像装置 1 的透镜组件 1 13沿着挡风玻璃 42的弧面 421设置, 以避免使用者 2看到 失真的放大并等效位于远处的显示影像 1 101 '。 当驾驶座 43位于汽车 4的左侧时, 光学 成像装置 1设置于驾驶座 43前方的仪表板座 41 中,此时透镜組件 1 13沿着挡风玻璃 42 的弧面 421设置, 壳体 10的中心线 C1相对于汽车 4的驾驶座 43的中心线 C2往右倾斜 一角度, 换句话说, 壳体 10的中心线 C1相对使用者 2的直视的中心线往使用者 2的右 侧倾斜角度, 角度依据弧面 421 的曲率而定; 当驾驶座 43位于汽车 4的右侧时, 光学 成像装置 1设置于驾驶座 43前方的仪表板座 41 中, 壳体 10的中心线 C1相对于驾驶座 43的中心线 G2往左倾斜一角度, 如此使透镜组件 1 13可沿着挡风玻璃 42的孤面 421 的曲率设置。
上述说明壳体 10的中心线 C1相对汽车 4的驾驶座 43的中心线 C2往右或左倾斜的 角度是依据挡风玻璃 42的弧面 421 的曲率而定, 于此进一步举例说明, 使用者 2的眼 睛 21至光学成像装置 1的距离(包含挡风玻璃折射距离)约 1米,挡风玻璃 42的弧面 421 的半径为 1500mm的状况下, 光学成像装置 1的壳体 10的中心线 C1相对于汽车 4的驾 驶座 43的中心线 C2向右或向左倾斜的角度约 5度。
再参阅图 8, 当光学成像装置 1装载于汽车 4的仪表板座 41之后, 挡风玻璃 42上 设置反射膜 422, 反射膜 422对应光学成像装置 1 的透镜組件 1 13, 并位于从透镜組件
1 13穿出的显示影像 1 101 的传递路径上,其中反射膜 422也可由或暗色膜或为镀膜玻璃 显示区替代。 当光学成像装置 1开始运作时, 显示組件 1 10所产生显示影像 1 101, 经由 传递路径与显示组件穿过透镜組件 1 13,并传递至挡风玻璃 42的反射膜 422,反射膜 422 反射显示影像 1 101 至用户 2的眼睛, 此时使用者 2会看到放大并等效位于远处的显示 影像 1 101, (虚像), 如此使用者 2于驾驶汽车 4时, 用户 2的视线聚焦于远处的路况, 同时也可观视放大并等效位于远处的显示影像 1 101, ,也表示用户 2于驾驶过程中不用 改变其眼睛的焦距, 即可观视放大并等效位于远处的显示影像 1 10Γ , 并透过放大并等 效位于远方的显示影像 1 101, 得知目前汽车 4的信息(例如:车速、油量、转速、溫度等)。
再参阅图 5, 并同时参阅图 10及图 1 1, 其为本发明的第二实施例的光学成像装置 的另一剖面图及调整壳体角度的示意图; 如图所示, 每一使用者 2的身长不同而使其坐 在驾驶座 43的高度不同, 导致用户 2的视角不同, 为了让使用者 2可观看完整的显示 影像, 而本实施例的光学成像装置 1更包含外壳体 12, 壳体 10的两侧分别具有枢接轴 103, 外壳体 12具有对应两个枢接轴 103的两个枢接孔 121, 壳体 10的两个枢接轴 103 枢接于外壳体 12的两个枢接孔 121, 以套设于壳体 10的外侧, 并使壳体 10可相对外壳 体 12转动。 然本实施例的光学成像装置 1 更包含角度调整机构 13, 角度调整机构 13 设置于外壳体 12内, 并对应壳体 10的底部 101, 角度调整机构 13推动壳体 10的底部 101, 使壳体 10相对于外壳体 12转动, 进而调整透镜组件 1 13相对于挡风玻璃 42的角 度。 所以使用者 2可依据其身长透过角度调整机构 13调整透镜组件 1 13相对于挡风玻 璃 42的角度, 直到使用者 2观看到完整地放大并等效位于远处的显示影像 1 101 '为止。
本实施例的角度调整机构 13包含驱动組件 131及推动组件 132,推动組件 132设置 于驱动組件 131 , 驱动组件 131 设置于外壳体 12 内, 推动组件 132的一端抵接于壳体 10的底部 101。 当驱动组件 131驱动推动组件 132往底部 101前进时, 以推动底部 101, 使壳体 10相对于外壳体 12转动, 进而调整透镜组件 1 13相对于挡风玻璃 42的角度。 所以用户 2欲调整透镜組件 1 13相对于挡风玻璃 42的角度时, 只要启动驱动组件 131 即可。 上述驱动组件 131 可为马达, 推动组件 132可为螺杆, 当然角度调整机构 13可 为其他型态, 于此不再赘述。
再参阅图 8, 每一使用者 2的脚长或手臂长不同, 因此坐在驾驶座 43的使用者 2 至挡风玻璃 42的距离 d1也不同, 为了使每一使用者 2可看到完整的显示影像 1 101 ', 本实施例的光学成像装置 1依据用户 2至挡风玻璃 42的距离 d1调整显示組件 1 10所显 示的显示影像 1 101的面积大小。请一并参阅图 12A及图 12B,其为本发明的第二实施例 的光学成像装置的显示影像的调整示意图; 如图所示, 本实施例的显示組件 1 10具有显 示区域 1 102,显示影像 1 101位于显示区域 1 102内,其面积可小于或等于显示区域 1 102 的面积, 然显示組件 1 10的显示影像 1 101 的面积调整是透过显示组件 1 10的内建处理 器并依据使用者 2至挡风玻璃 42的距离 d1不同进行调整。
当使用者 2与挡风玻璃 42间的距离 d1縮短(即用户 2与透镜組件 1 13间的距离縮 短)时, 依据使用者 2与挡风玻璃 42间的距离扩大显示組件 1 10的显示影像 1 101 的面 积; 反之, 当使用者 2与挡风玻璃 42间的距离 d1增加(即用户 2与透镜組件 1 13间的 距离增加)时, 依据使用者 2与挡风玻璃 42间的距离 d1缩小显示影像 1 101的面积。
本实施例的透镜组件 1 13的两表面的中心可能因制作过程中产生误差, 即透镜组件 1 13的两表面的中心并非位于同一直线,如此使放大并等效位于远处的显示影像 1 101, 产生偏移,导致使用者 2无法观看完整的放大并等效位于远处的显示影像 1 101, 。此时, 请参阅图 13, 用户 2依据放大的显示影像 1 10Γ 的偏移量(如 X及 Y方向的偏移量)调 整显示组件 1 10的显示影像 1 101于显示区域 1 102的位置, 使放大并等效位于远处的显 示影像 1 10Γ 完整的呈现。 上述显示影像 1 101 的位置调整也是透过显示组件 1 10的内 建处理器依据放大的显示影像 1 10Γ 的偏移量进行调整。
再参阅图 5, 并同时参阅图 14, 其为本发明的第二实施例的光学成像装置的显示组 件的背光模块的示意图; 如图所示, 本实施例的显示組件 1 10使用具有高亮度的显示組 件 1 10, 所以本实施例的显示组件 1 10的背光模块使用发光二极管背光模块 1 103, 如此 发光二极管背光模块 1 103可提供高亮度的显示影像 1 101, 如此本实施例的光学成像装 置 1所产生的放大并等效位于远处的显示影像 1 101, 可清晰地让使用者观视。
另参阅图 8, 本实施例的光学成像装置 1更包含感测组件 14 (如: CMOS传感器), 感 测組件 14设置于汽车 4内, 例如方向盘的前方, 并设置于光学成像装置 1的壳体 10的 外侧。 感测组件 14可对光学成像装置 1 的外部环境的亮度或色彩进行感测, 显示組件 1 10依据环境亮度或色彩调整发光二极管背光模块 1 103的亮度或调整显示组件 1 10所显 示的显示影像的色彩, 以产生清楚的显示影像 1 101,进而获得于此环境下清晰的放大并 等效位于远处的显示影像 1 10Γ 。 于此更进一步说明感测組件 14如何感测环境亮度, 请一并参阅图 15, 其为本发明的第二实施例的光学成像装置的感测組件的感测示意图; 如图所示, 感测组件 14对光学成像装置 1的外部环境进行拍摄, 并产生影像 5, 然后于 影像 5上取多个取样点 51,并计算该些取样点 51的亮度值的平均值,然后显示组件 1 10 依据平均值调整发光二极管背光模块 1 103的亮度。
上述说明利用影像 5 计算出环境亮度, 并依据环境亮度调整发光二极管背光模块 1 103的亮度。于下述说明如何依据影像 5的环境色彩调整显示组件 1 10所显示的显示影 像 1 101的色彩, 其主要依据影像 5判断出环境色彩, 然依据显示影像 1 101 的色彩与环 境色彩的比对调整显示影像 1 101 的色彩, 即进行显示影像 1 101的色彩与环境色彩的反 差色改变 。 举例来说, 在晚上的时候, 若是撷取到的影像 5的环境色彩是黑色或暗色, 那么可以调整显示组件 1 10, 让显示影像 1 101 为亮色。反之, 在白天的时候或是前方有 白色车子,如此撷取到的影像 5的环境色彩为白色或亮色, 那么可以调整显示组件 1 10, 让显示影像 1 101 为暗色。 经上述方式调整后, 光学成像装置 1 于任何环境下使用, 可 获得清晰的放大并等效位于远处的显示影像 1 101,
再参阅图 14,又因本实施例的光学成像装置 1的显示組件 1 10使用发光二极管背光 模块 1 103, 发光二极管背光模块 1 103容易产生高溫, 所以本实施例的发光二极管背光 模块 1 103 的电路板使用陶瓷基板 1 104, 并于陶瓷基板 1 104 的后端增设散热組件 1 105 (如: 散热鰭片), 以将发光二极管背光模块 1 103所产生的热排出至外部, 进而降 低光二极管背光模块 1 103的温度。
再参阅图 8, 本实施例的光学成像装置 1 更包含光感测模块 15, 光感测模块 15设 置于壳体 10的外側, 并位于汽车 4的仪表板座 41 内, 请一并参阅图 16, 其为本发明的 图 8的 A区域的放大图; 如图所示, 光感测模块 15具有感测端 151, 壳体 10的中心线 C3相对水平面 H倾斜第一角度 a1, 光感测模块 15的感测端 151 的中心线 C4也相对水 平面 H倾斜第一角度 a1, 如此于光学成像模块 1 1 的影像输出端 1 131 的透镜組件 1 13 与光感测模块 15的感测端 151棵露于仪表板座 41的表面, 并朝向同一方向。
本实施例的光感测模块 15包含中空的圆柱体 152及光感测组件 153, 光感测組件 153设置于圓柱体 152内, 并位于圓柱体 152的底部。 光感测组件 153的上方称为感测 端 151。 当然光感测模块 15也有其他型态, 请参阅图 17, 中空的圓柱体也可由二薄板 154取代,其中一薄板 154具有孔洞 1541,光感测组件 153对应孔洞设置于另一薄板 154 上; 或者直接省略圆柱体 151 的设置也可。
请参阅图 18, 其为本发明的第二实施例的光学成像装置的光感测模块的使用状态 图; 如图所示, 因光学成像装置 1 的透镜組件 1 13与光感测模块 15的光感测组件 153 朝向同一方向, 汽车 4外部的太阳光 L相对透镜組件 1 13及光感测模块 15的光感测組 件 153的照射角度相同。 当汽车 4外部的太阳光 L垂直穿过透镜组件 1 13时, 太阳光 L 也会垂直照射于光感测模块 15的光感测组件 153,此时光感测组件 153所接受的太阳光
L的照射量, 正比于太阳光 L对壳体 10内的光学成像模块 11 的照射量, 当光感测组件 153感测太阳光 L对光学成像模块 11的照射量超过门槛值,并传送第一控制信号至角度 调整机构 13,角度调整机构 13接收第一控制信号并依据第一控制信号调整壳体 10的角 度。 当壳体 10转动一角度时, 改变了透镜組件 113相对于太阳光 L的角度, 进而改变 透镜组件 113相对于挡风玻璃 42的角度, 即使光学成像模块 11 的影像输出端 1131 的 透镜組件 113与光感测模块 15的感测端 151无朝向同一方向,使汽车 4外部的太阳光 L 不会垂直穿过透镜组件 113, 以避免光学成像模块 11的組件产生热损坏。
壳体 10经角度调整后, 当光感测组件 153的感测太阳光 L对光学成像模块 11 的照 射量(即光感测组件 153所接受的太阳光 L的照射量)小于门槛值时, 光感测组件 153产 生第二控制信号并传送第二控制信号至角度调整机构 13, 角度调整机构 13依据第二控 制信号调整壳体 10的角度, 使壳体 10恢复成原始状态, 即使光学成像模块 11 的影像 输出端 1131 与光感测模块 15的感测端 151朝向同一方向(如图 16所示)。
请参阅图 19A及图 19B, 其为本发明的第五实施例的光学成像装置的遮光件的使用 状态图; 如图所示, 上述实施例是利用角度调整机构 13调整壳体 10的角度, 使外部太 阳光 L不会垂直穿过透镜组件 113, 以避免光学成像模块 11 内产生热损害。然本实施例 的光学成像装置 1 不须调整壳体 10的角度, 也可避免外部太阳光 L垂直穿过透镜組件 113而进入光学成像模块 11 内, 本实施例的光感测模块 15控制覆盖于光学成像模块 11 的影像传输端 1131 的遮光件 16的开关或颜色变化, 本实施例的遮光件 16位于透镜组 件 113的上方。
本实施例的遮光件 16为遮光帘, 当光学成像装置 1正常使用时, 遮光件 16为关闭 状态, 即无遮蔽光学成像模块 11 的透镜组件 113, 也表示无遮蔽光学成像模块 11 的影 像输出端 1131, 使外部太阳光 L可穿过透镜組件 113照射至光学成像模块 11; 光学成 像装置 1无法正常使用时, 遮光件 16为启动状态, 即遮蔽光学成像模块 11的透镜组件 113, 也表示遮光件 16遮蔽光学成像模块 1 的影像输出端 1131, 以阻隔外部太阳光 L 穿透透 ΐ^进入光学 ¾¾ 5ΰΤ。 实施例 遮光件 16 ΐΐϊ ¾^Το的开口
100, 并位于透镜組件 113的上方, 以遮蔽光学成像模块 11的影像输出端 1131。 当然本 实施例的遮光件 16也可设置于仪表板 7^1, 并位于透镜组件 113的上方, 遮光件 16 仅要对应透镜組件 113设置,即达到可遮蔽光学成像模块 11的影像输出端 1131的目的。
当光感测组件 153感测太阳光 L对光学成像装置 1 的照射量(即光感测組件 153所 接受的太阳光 L的照射量)超过门槛值, 即外部太阳光 L直接垂直穿过透镜組件 113而 进入光学成像模块 11 时, 光感测组件 153产生并传送第一控制信号至遮光件 16, 遮光 件 16依据第一控制信号启动, 使遮光件 16为启动状态, 以遮蔽透镜组件 113, 即阻隔 外部太阳光 L进入透镜组件 113(如图 19Α所示)。 之后, 当光感测組件 153感测太阳光 L对光学成像装置 1 的照射量(即光感测组件 153所接受的太阳光 L的照射量)小于门槛 值时, 也表示太阳光 L未垂直穿过透镜组件 113, 此时, 光感测组件 153产生第二控制 信号并传送第二控制信号至遮光件 16, 遮光件 16依据第二控制信号关闭, 即使遮光件 16为关闭状态, 进而使外部太阳光 L可穿过透镜组件 113, 而使光学成像模块 11 可正 常使用(如图 19Β所示)。
另外, 请参阅图 20Α及图 20Β, 其为本发明的第六实施例的光学成像装置的遮光件 的使用状态图; 如图所示, 上述实施例的遮光件 16为遮光帘, 而本实施例的遮光件 16 是显示玻璃替代遮光帘, 其中显示玻璃是于二玻璃之间灌注液晶, 控制液晶而改变显示 玻璃为透明状态、半透明状态或黑色状态。遮光件 16受光感测模块 15的光感测组件 153 的控制,当光感测組件 153感测太阳光 L对光学成像模块 11的照射量(即光感测组件 153 所接受的太阳光 L的照射量)未超过门槛值时,即太阳光 L未直接垂直穿过透镜組件 113, 此时遮光件 16为透明状态, 遮光件 16无遮蔽透镜組件 113, 即无遮蔽光学成像模块 11
的影像输出端 1 131, 使外部太阳光 L可穿过透镜组件 1 13而进入光学成像模块 1 1, 光 学成像模块 1 1可正常使用, 如图 20B所示。
当光感测組件 153感测太阳光 L对光学成像模块 1 1的照射量(即光感测组件 153所 接受的太阳光 L的照射量)超过门槛值时, 即太阳光 L直接垂直穿过透镜组件 1 1 3, 此时 遮光件 16可选择为半透明状态或黑色状态, 如图 20A所示, 当遮光件 16为半透明状态 时, 可减少外部太阳光 L透过透镜組件 1 13进入光学成像模块 1 1 的照射量, 以减少太 阳光 L进入光学成像模块 1 1所产生的热损害; 当遮光件 16为黑色状态时, 可遮蔽透镜 组件 1 13, 即遮蔽光学成像模块 1 1 的影像输出端 1 131, 以阻隔外部太阳光 L进入光学 成像模块 1 1 内。 然本实施例的遮光件 16亦可设置于壳体 10内, 并覆盖光学成像模块 1 1 的影像输出端 1 131, 而本实施例的遮光件 16位于透镜組件 1 13的下方, 遮光件 16 仅要对应透镜组件 1 13设置, 也可达到阻隔或减少外部太阳光 L进入光学成像模块 1 1 内, 如图 21所示。 本实施例的遮光件 16也可由单向玻璃替代。
上述第五实施例至第七实施例均于使用者驾驶过程中太阳光 L对光学成像装置 1的 照射量(即光感测组件 153所接受的太阳光 L的照射量)超过门槛值时, 调整壳体 10的 角度或启动遮光件 16遮蔽透镜组件 1 13, 另当汽车 4未使用时, 也可调整壳体 10的角 度或启动遮光件 16遮蔽透镜组件 1 13, 以保护光学成像装置 1, 避免光学成像装置 1 内 的组件产生热损害。
然上述实施例的光感测模块 15均设置于壳体 10的外侧, 并与壳体 10分离, 请一 并参阅图 22, 当然光感测模块 15也可直接与壳体 10相连,光感测模块 15的感测端 151 与透镜組件 1 13朝向同一方向, 当壳体 10依据使用者 2至挡风玻璃 42的距离转动时, 光感测模块 15也可同时随壳体 10转动, 光感测模块 15的感测端 151 与透镜組件 1 13 朝向同一方向, 以准确感测太阳光 L对光学成像装置的照射量。
再参阅图 2, 若上述实施例的光学成像装置 1 使用长焦距的透镜組件 1 13, 所以第 一传递路径 S1、第二传递路径 S2及第三传递路径 S3的总长度也依据透镜組件 1 13的焦 距而增长, 若第一传递路径 S1 不变时, 第三传递路径 S3会增长, 也表示壳体 10的纵 向长度也会增加, 进而增加光学成像装置 1的体积。
请参阅图 23所示, 其为本发明的第九实施例的光学成像装置的剖面图; 如图所示, 为了缩小光学成像装置 1的体积, 除了增加第一反射组件 1 1 1的数量, 可增设至少一个 第一透镜組件 17, 与目前透镜組件 113并排, 以縮短透镜組件 113的焦距, 如此第一传 递路径 S1、 第二传递路径 S2及第三传递路径 S3的总长度也缩短。 当第一传递路径 S1 的长度不变时, 第三传递路径 S3可缩短, 以缩短壳体 10的纵向长度, 进而缩小光学成 像装置 1的体积, 同时可减少光学成像装置 1所产生的显示影像发生弧形失真的状况, 以維持显示影像的显示质量。
再参阅图 6, 为了让使用者 2的双眼 21 均能看到完整的放大的显示影像 1 101, , 所以第一实施例的透镜组件 1 13的宽度 W大于使用者 2的两眼 21的间距 d,如此使光学 成像装置 1所产生的显示影像 1 10Γ位于两眼 21的重叠观看区域 R内。 因透镜组件 1 13 的宽度大于用户的两眼的间距, 用户透过透镜組件 1 13 产生可观看区域 P (包含用户 2 的单眼 21可观看的观看区域 P1、 P2), 而完整的显示影像 1 10Γ 位于两眼 21的可观看 区域 P的重叠观看区域 R内, 如图所示, 其仅位于可观看范围 P的中间区域, 可观看范 围 P的左侧及右侧并无影像可观看。
请参阅图 24、 图 25及图 26, 其为本发明的第十实施例的光学成像装置的示意图、 成像示意图及可观看区域所显示的内容的示意图; 如图所示, 因此本实施例的光学成像 装置 1增加两个辅助显示組件 18,两个辅助显示組件 18分别位于显示组件 1 10的两侧, 并较显示组件 1 10靠近透镜組件 1 13。 二辅助显示组件 18可分别显示辅助影像 181, 辅 助影像 181可为通知来电的图像、 来电者的图像等。 用户 2透过透镜組件 1 13可观看到
放大的两个辅助影像 18Γ 位于显示影像 110Γ 的两側, 以填满可观看区域 P。 当然也 可以仅设有一个辅助显显示組件 1, 于此不再赘述。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式上的限制, 虽 然本发明已以较佳实施例揭露如上, 然而并非用以限定本发明,任何熟悉本专业的技术 人员, 在不脱离本发明技术方案范围内,当可利用上述揭示的技术内容作出些许更动或 修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容, 依据本发明的技 术实质对以上实施例所作的任何简单修改、 等同变化与修饰, 均仍属于本发明技术方案 的范围内。
