Description

一种投影仪壳体及投影仪 技术领域
本申请涉及但不限于投影设备领域，尤其涉及一种投影仪壳体及投影仪。
背景技术
目前，在微型投影仪产品中，由于光机特别是激光光源的光机功耗较大，易造成整机发热量过大的问题，尤其是光机的主板投影芯片，其发热更是严重。如果主板投影芯片等部件的温度过高会降低用户体验甚至造成器件烧坏，因此，此类产品大多需要增加风扇来完成***散热，风扇散热***一般需要在一级外观面上开大量的孔以形成风道来实现空气流通，但是，大量的开孔不但影响了产品的美观，还容易造成产品进灰甚至小物体的进入，进而造成产品损坏。
另外，目前市场上的投影仪产品，大多是在投影仪壳体的前端中部设置一个支架或螺旋柱调节投影仪的角度，但是由于使用环境的限制，比如桌面不平或者产品组装公差引起的投影画面歪斜，使得采用一个支架或螺旋柱调节角度无法矫正由于组装以及放置位置引起的投影画面水平歪斜。此外，相关的投影仪采用内置程序只能进行简单的T形矫正，无法完成水平矫正；并且大多数投影仪产品的支架或螺旋柱无法完成仰角连续调节。
针对相关技术中的投影仪为了实现散热而大量开孔造成的影响产品美观的问题，目前尚未提出有效的解决方案。

支架20与滑动盖板30传动连接，滑动盖板30由支架20驱动，支架20闭合在壳本体10上时带动滑动盖板30处于第一位置，即将第一散热孔11闭合，支架20从壳本体10上打开时带动滑动盖板30处于第二位置，即将第一散热孔11打开。
可选地，支架20通过传动组件40与滑动盖板30传动连接，如图6所示，传动组件40包括：固定块41、传动轴42、主动齿轮43和从动齿轮44，固定块41设置在滑动盖板30的内侧壁上，固定块41上具有沿其运动方向的螺孔，传动轴42上具有与该螺孔相匹配的外螺纹，传动轴42穿过固定块41上的螺孔与固定块41螺接，传动轴42旋转时通过固定块41驱动滑动盖板30在第一位置和第二位置之间运动。
主动齿轮43设置在支架20与壳本体10的铰接轴上随支架20的开启和闭合而转动，从动齿轮44连接在传动轴42的一端，主动齿轮43与从动齿轮44相互啮合，从而在支架20开启或闭合时驱动传动轴42转动，进而带动滑动盖板30开启或关闭。可选地，主动齿轮43为不完全齿轮，从而能够实现滑动盖板30的延迟打开，即在刚开启支架20时，滑动盖板30不动作，等一定时间后再随支架20开启。
本实施例还提供了一种投影仪，包括壳体和设置在壳体内的光机50和风扇60，壳体为上述实施例的投影仪壳体。
为了实现投影仪更好地散热，如图7所示，壳本体10内设置有散热风道，壳本体10的相对两端均设置有第一散热孔11和第二散热孔12，第一散热孔11位于壳本体10的底壁上，第二散热孔12位于与底壁相邻的侧壁上。散热风道的进气口与每个第一散热孔11和位于壳本体10一端的第二散热孔12连通，散热风道的出气口与位于壳本体10另一端的第二散热孔12连通。
可选地，散热风道包括两条，一条由壳本体10第一端的第一散热孔11和第二散热孔12进风，即图7中左侧的第一散热孔11和第二散热孔12进风，穿过壳本体10内部和风扇60，由壳本体10第二端的第二散热孔12出风，即图7中右侧的第二散热孔12出风；另一条由壳本体10第二端的第一散热孔11进风，即图7中右侧的第一散热孔11进风，该第一散热孔11与风扇60上下相对，风流经过风扇60后，同样由壳本体10第二端的第二散热孔12出风。
在投影仪中，光机50和主板芯片90的发热量较大，对于光机50，其DMD芯片和光源部分是发热量最大的区域，因此，可选地，光机50的DMD芯片设置在壳本体10第一端的第一散热孔11的内侧，即DMD芯片同时靠近壳本体10第一端的第一散热孔11和第二散热孔12两个进风口，使DMD芯片更快地散热。
在风道中还设置有第一散热块71，在壳本体10的第二端的第二散热孔12处还设置有第二散热块72，第一散热块71与光机50的光源部分接触，第一散热块71通过散热管80与第二散热块72连接，从而使光机50的光源更好地散热。
主板芯片90通过散热管80与第二散热块72连接，将主板芯片90产生的热量传导至第二散热块72处，并在风道内风流的作用下由出风口带出。
以上所述仅为本实用新型的可选实施例而已，并不用于限制本实用新型实施例，对于本领域的技术人员来说，本实用新型实施例可以有多种更改和变化。凡在本实用新型实施例的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型实施例的保护范围之内。
工业实用性
应用本实用新型实施例的技术方案的投影仪壳体，通过在壳本体上设置可开启和闭合的支架，在支架的内侧设置有第一散热孔，支架闭合在壳本体上时遮挡住第一散热孔，从而既能满足投影仪的散热要求，也可以在不使用时将散热孔遮挡住，提升投影仪壳体的美观性，解决了相关技术中的投影仪为了实现散热而大量开孔造成的影响产品美观的问题。
