Description

数字微镜组件安装结构和图像显示装置 技术领域
本发明涉及数字光处理技术领域，更具体地说，涉及一种数字微镜组件安装结构和图像显示装置。
 背景技术
投影仪由其成像原理分为CRT三枪投影仪、LCD投影仪和DLP投影仪，其中，DLP投影仪由其原生对比度高、机器小型化、光路采用封闭式等优点被广泛应用。
技术问题
DLP投影仪中，数字微镜组件（Digital Micromirror Devices，简称DMD）是重要部件。目前，数字微镜组件的安装结构主要有两种，一种为：印制电路板（Printed Circuit Board，简称PCB）与壳体直接通过锁紧螺钉连接，利用印制电路板压紧数字微镜组件；另一种为：在印制电路板上增加一个压板，压板与壳体直接通过锁紧螺柱连接，且压板直接与印制电路板抵接，从而通过压板压紧印制电路板，进而压紧数字微镜组件。
但是，第一种安装结构中，印制电路板与锁紧螺钉之间有间隙，使得印制电路板在压紧数字微镜组件时承受弯矩；第二种安装结构中，压板与锁紧螺柱之间有间隙，使得压板在压紧数字微镜组件时承受弯矩，又由于压板直接与印制电路板抵接，导致印制电路板也承受弯矩。因此，上述两种安装结构中，在压紧数字微镜组件时，印制电路板均要承受弯矩，产生弯曲应力，影响数字微镜组件的稳定性。
综上所述，如何避免印制电路板承受弯矩，以避免影响数字微镜组件的稳定性，是目前本领域技术人员亟待解决的问题。
 技术解决方案
有鉴于此，本发明的目的是提供一种数字微镜组件安装结构，避免印制电路板承受弯矩，以避免影响数字微镜组件的稳定性。本发明的另一目的是提供一种具有上述数字微镜组件安装结构的图像显示装置。
为了达到上述目的，本发明提供如下技术方案：

 有益效果
本发明提供的数字微镜组件安装结构的压紧原理为：通过压板与壳体刚性连接，使得压板通过弹性件将印制电路板压紧于数字微镜组件，又由于数字微镜组件由壳体支撑，则实现了对数字微镜组件的夹紧，即完成了对数字微镜组件的安装。
本发明提供的数字微镜组件安装结构，由于压板与壳体刚性连接，则压板在压紧时会承受弯矩，产生弯曲应力，发生变形，又由于弹性件位于压板和印制电路板之间，则弹性件根据自身的弹性会补偿压板的变形，从而避免了印制电路板承受弯矩，即避免了印制电路板产生弯曲应力，进而避免了影响数字微镜组件的稳定性。
同时，本发明提供的数字微镜组件安装结构，由于弹性件位于压板和印制电路板之间，则可通过弹性件控制压板施加到数字微镜组件上的压紧力，进一步地控制数字微镜组件的稳定性。
 附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为本发明实施例提供的数字微镜组件安装结构的结构示意图。
上图1中：
1为数字微镜组件、11为数字微镜本体、12为安装座、2为支撑柱、3为印制电路板、4为压板、5为锁紧螺钉、6为弹性件、7为壳体。
 本发明的最佳实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，本发明实施例提供的数字微镜组件安装结构，包括：壳体7，印制电路板3，弹性件6和压板4；其中，壳体7用于支撑数字微镜组件1，压板4、弹性件6和印制电路板3用于与壳体7配合压紧数字微镜组件1。具体地，压板4与壳体7刚性连接，压板4、弹性件6和印制电路板3依次连接。可以理解的是，壳体7的支撑部位于数字微镜组件1的一侧，印制电路板3、弹性件6和压板4均位于数字微镜组件的1的另一侧。
上述数字微镜组件安装结构的压紧原理为：通过压板4与壳体7刚性连接，使得压板4通过弹性件6将印制电路板3压紧于数字微镜组件1，又由于数字微镜组件1由壳体7支撑，则实现了对数字微镜组件1的夹紧，即完成了对数字微镜组件1的安装。
本发明实施例提供的数字微镜组件安装结构，由于压板4与壳体7刚性连接，则压板4在压紧时会承受弯矩，产生弯曲应力，发生变形，又由于弹性件位于压板4和印制电路板3之间，则弹性件6根据自身的弹性会补偿压板4的变形，从而避免了印制电路板3承受弯矩，即避免了印制电路板3产生弯曲应力，进而避免了影响数字微镜组件1的稳定性。
同时，由于弹性件6位于压板4和印制电路板3之间，则上述数字微镜组件安装结构，可通过弹性件6控制压板4施加到数字微镜组件1上的压紧力，进一步地控制数字微镜组件1的稳定性。
上述弹性件6可弹性垫片、弹性柱、弹簧等部件，为了便于安装，优先选择弹性件6为弹性垫片。这样，也便于补偿压板4的变形。
对于弹性垫片的类型，可根据变形量和其他需要进行选择。优选地，弹性垫片为硅胶垫。当然，也选择弹性垫片为橡胶垫，并不局限于上述实施例。
对于弹性垫片的形状，可根据压板4和印制电路板3的形状进行设计，例如方形或者圆形等，本发明实施例对此不做限定。
为了提高弹性件6的功能，优先选择弹性件6位于印制电路板3的中部。具体地，若弹性件6为弹性垫片，则弹性垫片的中心轴线与印制电路板3的中心线共线。可以理解的是，印制电路板3的中心线沿印制电路板3的厚度方向延伸。若弹性件6为弹性柱或者弹簧等，弹性件6至少为两个，且沿圆环均匀分布，弹性件6形成的圆环的中心线与印制电路板3的中心线共线。
当然，也可根据压板4的变形，调整弹性件6的位置，并不局限于上述实施例。
上述数字微镜组件安装结构中，压板4与壳体7刚性连接，存在多种方式，例如焊接、螺纹连接件连接、铆接、粘接等。压板4位于印制电路板3远离数字微镜组件1的一侧，则需要在壳体7上设置向压板4凸出的结构，以实现与压板4的刚性连接。
为了便于压板4与壳体7刚性连接，上述数字微镜组件安装结构还包括：与壳体7固定相连的支撑柱2；其中，压板4通过支撑柱2与壳体7刚性连接。可以理解的是，压板4与支撑柱2刚性连接。
优选地，上述压板4与支撑柱2通过锁紧螺钉5刚性连接。可以理解的是，支撑柱2内设有供锁紧螺钉5锁紧的螺纹孔。上述结构，方便了压板4与支撑柱2的安装和拆卸。当然，也可选择压板4与支撑柱2通过焊接实现刚性连接，并不局限于上述实施例。
为了简化组装，上述支撑柱2与壳体7为一体式结构，如图1所示。这样，简化了组装，方便了生产。当然，也可选择支撑柱2与壳体7焊接或者粘接相连，并不局限于上述实施例。
进一步地，上述印制电路板3套设于支撑柱2，如图1所示。这样，支撑柱2具有双重作用，方便了压板4与壳体7刚性连接的同时，实现了对印制电路板3的定位。具体地，支撑柱2没有支撑印制电路板3的底面。可以理解的是，印制电路板3的底面是指印制电路板3靠近数字微镜组件1的一面。这样，能够避免印制电路板3因支撑柱2的作用力而承受弯矩。优选地，支撑柱2为等径柱体。
对于上述支撑柱2的数目，可根据实际需要进行设计，只有能够保证压板4与壳体7刚性连接即可。优选地，支撑柱2为偶数个，且支撑柱2均匀分布于压板4的两端。具体地，以支撑柱2是两个为例，压板4的一端由一个支撑柱2支撑，压板4的另一端由另一个支撑柱2支撑。以支撑柱2是四个为例，压板4的一端由两个支撑柱2支撑，压板4的另一端由另外两个支撑柱2支撑。
当然，也可选择支撑柱2至少为三个，且沿压板4的周向均匀分布。具体地，所有的支撑柱2围成圆环形，任意相邻的两个支撑柱2之间的夹角相等。
上述压板4的形状和大小，可根据实际需要进行设计，本发明实施例对此不做限定。
基于上述实施例提供的数字微镜组件安装结构，本发明实施例还提供了一种图像显示装置，该图像显示装置包括：数字微镜组件，用于安装该数字微镜组件的安装结构；其中，该安装结构为上述实施例所述的数字微镜组件安装结构。
由于上述数字微镜组件安装结构具有上述技术效果，本发明实施例提供的图像显示装置具有上述数字微镜组件安装结构，则本发明实施例提供的图像显示装置也具有相应的技术效果，本文不再赘述。
上述图像显示装置中，数字微镜组件1包括：安装座（socket）12和固定于安装座12的数字微镜本体11；其中，安装座（socket）12与印制电路板3抵接，数字微镜本体11与壳体7抵接，数字微镜本体11与壳体7抵接指的是壳体7上延伸出的凸起以不影响数字微镜本体11出光的方式抵接在数字微镜本体的外周上。安装座12具有引脚，安装座12与数字微镜本体11抵接的一面通过引脚与数字微镜本体电连接，安装座12与印制电路板3抵接的一面通过引脚电连接至印制电路板3上的相应接触点。实际应用中数字微镜本体11通常为德州仪器的DMD芯片，在理论上数字微镜本体11和安装座12也可以成为一个整体，在此情形下，数字微镜组件11从外观上也可以是一个部件。因此，本文中数字微镜组件11是指由独立的DMD与socket形成的组件，也可以是DMD与socket集成后的总成。
上述图像显示装置中，为了保证正常运行，需要设置散热器。此时，上述图像显示装置包括散热器。由于压板4与壳体7刚性连接，优先选择散热器安装于压板4，使得整个图像显示装置的结构更为紧凑。进一步地，散热器通过螺纹连接件安装于压板4。当然，也可选择散热器以其他方式进行安装，例如焊接、铆接等，并不局限于此。
上述图像显示装置可为投影仪、显微镜等，本发明实施例对图像显示装置的具体类型不做限定。
对所公开的实施例的上述说明，使本领域技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
