Description

一种带投影功能的汽车后视装置 技术领域
本实用新型涉及汽车配件领域， 更具体地说，涉及一种带投影功能的汽车后 视装置。 背景技术
说 在很多特殊行业， 显示器上的图像需要在阳光下或强光下被人眼看得清楚， 比如汽车后视镜显示器， 为了让驾驶员看得书清楚， 需要后视镜有特别亮的屏幕， 而且屏幕需要足够大，由于各种原因，现在市面上的显示器屏幕都有偏暗的现象。 要解决屏幕不够大和偏暗的问题， 传统的方法， 要么是提高显示屏背光亮度， 要 么将倒车后视镜采用大显示屏， 这样虽然可以使显示效果得到改进， 但是， 仍然 无法达到图像超大超亮显示的效果。 实用新型内容 本实用新型所要解决的技术问题是提供一种制造成本低、显示质量高的带投 影功能的汽车后视装置， 其通过投影仪对画面的投射， 从而达到图像超大超亮显 示的效果。
为了解决上述技术问题， 本实用新型采用了以下技术方案：
一种带投影功能的汽车后视装置，包括后视镜和投影仪，所述后视镜包括外 壳、 以及设于外壳内的显示模组和控制模组， 所述投影仪包括投影主机和投影屏 幕， 所述投影屏幕设置于汽车挡风玻璃上， 所述投影主机与控制模组以及显示模 组电联接。
所述投影主机设置于外壳内。
所述外壳内还设有投影仪固定座， 所述投影主机上设有夹球装置， 所述投影 主机外置于后视镜外部， 通过夹球装置与后视镜内部的投影仪固定座活动连接。
所述投影屏幕设置于汽车挡风玻璃外侧。
所述投影屏幕设置于汽车挡风玻璃内侧。 所述投影仪为微型 LED投影仪或微型激光投影仪或微型红外投影仪。
本实用新型采用上述结构， 投影主机既可内置于后视镜外壳内， 也可以通过 一个夹球装置连接在后视镜外面， 拆装方便， 可灵活调节角度； 投影仪内置在后 视镜内部， 可通过调整后视镜和镜头， 将图片投射到挡风玻璃上， 操作方便。 屏 幕既可贴在汽车挡风玻璃的里面， 也可贴在汽车挡风玻璃的外面， 投影仪通过投 射图像到挡风玻璃上的投影， 显示在屏幕上， 既可让车里的驾驶员看到投影的图 像， 也可让外面的人看到， 显示画说面大而且亮度高， 便于驾驶员观察行车周边的 情况。 另外， 普通的投影仪由于体积很大， 价格昂贵， 很难与后视镜做成一个一 体化产品， 本发明所采用的微型投影仪， 它不但体积小， 而且价格相对便宜， 即

实施例 1 :
如图 1-4所示，一种带投影功能的汽车后视装置，包括后视镜 1和投影仪 2, 后视镜 1包括外壳， 外壳由上盖 11和下盖 12组成， 上盖 1上设有按键 13和上 盖灯罩 20， 下盖 12上设有下盖灯罩 21和组合支架 22; 外壳内设有显示模组和 说
控制模组， 显示模组包括后视镜玻璃 14和后视镜显示屏 15， 控制模组包括 PCB 支架 16、 PCB板 17和支架固定座 18 ; 外壳内还设有投影仪固定座 19。 投影仪 2 书
包括投影主机 23和投影屏幕 24， 投影主机 23上设有夹球装置 25， 投影主机 23 外置于后视镜外部，通过夹球装置 25与后视镜内部的投影仪固定座 19活动连接， 投影屏幕设置于汽车挡风玻璃上，即可贴于汽车挡风玻璃内侧也可以贴于汽车挡 风玻璃外侧。
实施例 2:
如图 5所示， 一种带投影功能的汽车后视装置， 包括后视镜 1和投影仪 2， 后视镜 1包括外壳， 外壳由上盖 11和下盖 12组成， 上盖 1上设有按键 13和上 盖灯罩 20， 下盖 12上设有下盖灯罩 21和组合支架 22; 外壳内设有显示模组和 控制模组， 显示模组包括后视镜玻璃 14和后视镜显示屏 15， 控制模组包括 PCB 支架 16、 PCB板 17和支架固定座 18。投影仪 2包括投影主机 23和投影屏幕 24， 投影主机 23设置于后视镜外壳内部， 投影屏幕设置于汽车挡风玻璃上， 即可贴 于汽车挡风玻璃内侧也可以贴于汽车挡风玻璃外侧。
微型投影仪主要的工作原理都是由光源发出光， 通过一系列的光学照明系 统， 将光源的光均匀的照射到显示芯片上， 而信号通过电路***在显示芯片上实 现色阶以及灰阶， 显示出图像， 此后由投影前端的投影镜头将显示芯片上的图象 放大投射到相应的屏幕上。在投影***里面， 光学主要分为成像光学系以及照明 光学系， 而其中最为关键的元器件则为显示芯片以及照明组件（即光源）。本发明 的工作原理： 倒车摄像头与后视镜前置摄像头通过光电感应， 将图像画面传输给 后视镜， 投影仪中的光源通过对图像的照射， 将图像画面放大显示在挡风玻璃上 投影仪显示屏幕上， 从而被人眼所看到。 如图 6所示， 当汽车在行进中或在倒车 时， 按下后视镜按键， 后视镜开始工作， 后视镜显示器通过外置投像头， 将图案 显示在显示屏上， 此时画面很小， 由于车在行进中， 驾驶员不易看到显示屏上的 细节。 采用本实用新型的设计后， 打开投影仪功能， 如图 7所示， 微型投影仪主 机将显示屏上的图像放大投射到挡风玻璃上的投影屏幕上， 图像大而清晰， 行车 周边情况一目了然。 当微型投影仪组件内置时， 通过扭转后视镜显示器， 投影方 向可随着后视镜显示器的角度变化而变化， 从而调整到最佳投影角度； 如图 8所 示， 当微型投影仪组件外置时， 由于微型投影仪通过夹球装置与后视镜相连， 且 说
各种线束巧妙地穿过夹球装置， 通过调整微型投影仪角度， 从面获得最佳投影角 度。
虽然结合附图描述了本实用新型的实施书方式，但是本领域的技术人员可以在 所附权利要求的范围之内作出各种变形或修改，只要不超过本实用新型的权利要 求所描述的保护范围， 都应当在本实用新型的保护范围之内。
