本发明提供一种光学元件固定结构及应用该光学元件固定结构的光学设备，以解决现有技术中光学元件在固定过程中会破坏其光学性能影响整体效率或可靠性，影响使用效果的问题。
如图1所示，本发明提供的光学元件固定结构，包括壳体3、收容在壳体3内的光学元件1和用于固定光学元件1的弹性固定件2。弹性固定件2至少包括沿三个不同方向延伸的弹性延伸部，弹性延伸部抵接并固定光学元件1。
其中光学元件1可以为棱镜、方棒等任意的光学元件，其固定方式均可以采用本发明提供的固定结构，本实施方式以TIR棱镜为例进行说明。光学元件1包括用于接收入射光的受光面103和与受光面103分别相邻接的连接面，其中连接面包括一对第一表面101和连接两第一表面101的第二表面102。在本实施方式中，光学元件1为长方体结构，包括相互平行的两第一表面101和第二表面102，第二表面102为平面结构，共有两个，平行且分别设置在两第一表面101两侧，事实上，在可选择的其他实施方式中，光学元件1的结构并不限定于此，也可以为其他多面体结构或不规则结构，第二表面102也可以为曲面或多个平面形成的表面，只要包括至少两个用于实现固定的第一表面101，即是可以实施的。
壳体3包括与两第一表面相对的第一侧壁31和第二侧壁32。在本实施方式中，第一侧壁31和第二侧壁32平行设置。在本实施方式中，弹性固定件2包括分别与第一侧壁31相连的第一弹片21和与所述第二侧壁32相连的第二弹片22。第一弹片21和/或第二弹片22上至少包括沿不同方向延伸的三个弹性延伸部，弹性延伸部抵接并固定所述光学元件。
需要说明的是，第一弹片21和第二弹片22的结构既可以为完全相同，也可以不同。具体以本实施方式为例，第一弹片21和第二弹片22为两个结构相同的弹片，其相互对称地设置在光学元件1的两侧组成弹性固定件2。事实上，在可选择的其他实施方式中，第一弹片21和第二弹片22的结构也可以不完全相同，只要起到协同作用，共同固定光学元件的作用，即是可以实施的。
具体在本实施方式中，弹性延伸部为弹性压爪，包括受力方向相互垂直的X方向压爪201、Y方向压爪202和Z方向压爪203，X方向压爪201、Y方向压爪202和Z方向压爪203分别从不同方向上提供光学元件固定所需的力，使光学元件达到受力平衡实现稳定的固定。当然，在可选择的其他实施方式中，也可以为其他弹性结构，只要可以起到施加弹性力，固定光学元件的作用即是可以实施。不同弹性延伸部所提供的受力方向也可以为非垂直方向，只要能够提供不共面的多个不同方向的外力，使得光学元件达到受力平衡，即是可以实施的。
弹性固定件2与壳体3的连接可以为胶粘、点焊、也可以为螺钉固定，具体在本实施方式中，弹性固定件2上设置有向壳体3方向弯折延伸的固定部23，固定部23上设置有第一固定孔，壳体1的第一侧壁31与第二侧壁32上设置有与第一固定孔相匹配的第二固定孔33，进一步的，通过螺钉或螺栓等固定件将各个固定部23分别固定在壳体3的第一侧壁31或第二侧壁32上。优选的，第一侧壁31和第二侧壁32上还设置有向光学元件方向突出的固定柱，第二固定孔33设置在该固定柱的顶面和底面上，这样，可以进一步提供产品的固定可靠性。优选的，固定柱等数量且等间距地分别在第一侧壁31和和第二侧壁32上。弹性固定件2包括与第二固定孔33一一对应的多个固定部23，分别设置在第一弹片和第二弹片的周侧边缘，从而实现弹性固定件2的固定。
具体在本实施方式中，X方向压爪共有四个，两两一组分别设置在第一弹片21和第二弹片22上，为自第一弹片21和第二弹片22靠近受光面的一侧边缘弯折延伸形成，使得X方向压爪抵接在所述光学元件的受光面103的四角处。这样，既可以起到固定作用，也可以尽量减少对受光面的遮挡。
Y方向压爪设置在第一弹片21和第二弹片22中的至少一个上，优选的，第一弹片21和第二弹片22均设置有Y方向压爪，且第一弹片21和第二弹片22上Y方向压爪的数量不限，可以仅有一个，也可以为多个，Y方向压爪为自第一弹片21和/或第二弹片22向光学元件1的第一表面101方向延伸形成，使得Y方向压爪的自由端抵接在光学元件的第一表面101上。当然，也可以仅在第一弹片21和第二弹片22中的一个上设置Y方向压爪，另一个上不设置，而是直接与第一表面101相贴设，也是可以实施的。
Z方向压爪两两一组分别设置在第一弹片21和第二弹片22上，优选的，Z方向压爪与固定部23一一对应，为自固定部23向远离壳体方向延伸形成，Z方向压爪的自由端抵接在光学元件的第二表面102上。
在可选择的其他实施方式中，弹性固定件2也可以仅在光学元件1的一侧设置一个弹片，该弹片上设置有X方向压爪、Y方向压爪和Z方向压爪，三个压爪分别提供不同方向上的压力，光学元件的另一侧抵接在壳体上，也是可以实施的。
通过设置受力方向不同的X方向压爪201、Y方向压爪202和Z方向压爪203，从不同方向对棱镜等光学元件施加压力固定，可以保证光学元件的固定稳定性，同时压爪压力经过计算所得，既保证棱镜能稳定固定，又不能压裂棱镜。并且采用第一弹片21和第二弹片22两个分体式弹片的设计，可以节省物料成本，降低对光学元件的干扰，避免杂散光照射的问题。
本发明还提供一种使用上述的光学元件固定结构的光学设备，该光学设备可以是投影仪、舞台灯等。
本发明的有益效果是：区别于现有技术的情况，本发明提供一种光学元件固定结构，包括光学元件和用于固定所述光学元件的弹性固定件，弹性固定件包括分别与所述第一侧壁相连的第一弹片和与所述第二侧壁相连的第二弹片，所述第一弹片和/或所述第二弹片上至少包括三种沿不同方向延伸的弹性延伸部，所述弹性延伸部抵接并固定所述光学元件。利用三个受力方向不同的弹性延伸部施加的压力固定光学元件，可以降低加工难度，结构简单易操作，固定可靠性高，提高了产品的可靠性能。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
