具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
结合图1至图4所示，本实施例提供了一种光学元件的调节机构，该二维调节机构包括内框1、套设于内框1外围的外框3、套设于外框3外围的固定座4、用于内框1和外框3相连接的纵向变形件821、822、823、824、用于外框3和固定座4相连接的横向变形件811、812、813、814，用于驱动内框1横向左右移动的横向调节螺杆6、以及用于驱动外框3纵向上下移动的纵向调节螺杆7。
进一步的，为了便于外框3和内框1上下左右的移动，结合图1和图2所 示，本实施例中，内框1与外框3之间，以及外框3与固定座4之间均设置有间隙，且外框3和固定座4之间的水平间隙的间距，大于外框3和固定座4之间的竖直间隙的间距；内框1和外框3之间的竖直间隙的间距，大于内框1和外框3之间的水平间隙的间距；此外，横向变形件811、812、813、814设置于外框3和固定座4之间的水平间隙内，即如图2所示，横向变形件811及812水平设置于外框3和固定座4之间左边的水平间隙内，横向变形件813及814水平设置于外框3和固定座4之间右边的水平间隙内；纵向变形件821、822、823、824竖直设置于内框1和外框3之间的竖直间隙内，其布置方式与上述方式类似，在此不做赘述，外框1和内框3之间的水平间隙间距以及竖直间隙间距如上述方式设置能够使调节机构结构紧凑。
进一步的，本实施例中横向变形件811和812，与横向变形件813和814分别对称设置于横向调节螺杆6的轴线的两侧；纵向变形件821和822，与纵向变形件823和824分别对称设置于纵向调节螺杆7的轴线的两侧。
采用上述结构设计，通过横向变形件及纵向变形件的设置，使得内框1、外框、及固定座4连为一体，为了方便对光学元件2进行二维调节，本实施例中，横向调节螺杆6贯穿固定座4及外框3的侧壁使得驱动端抵于内框1的侧壁，进而通过调节横向调节螺杆6，驱使外框3、内框1、光学元件2能够整体实现水平运动；同理，由于纵向调节螺杆7贯穿固定座4的侧壁且驱动端抵于外框的侧壁，进而通过调节纵向调节螺杆7，驱使外框3能够实现竖直移动，由于内框1与外框3之间通过纵向变形件一体连接，进而带动内框1竖直运动；通过上述结构设计，能够方便快捷的实现安装有光学元件2的内框水平及竖直运动，继而实现光学元件的二维调节，为了对调节后的光学元件2的位置进行有效定位，本实施例中，横向调节螺杆6及纵向调节螺杆7上均螺纹连接有锁紧螺母9， 锁紧螺母9均位于固定座4的外侧且两者之间设置有垫片，以此使得调节后的光学元件2能够稳定可靠的定位。
此外，本实施例中内框1的中部贯穿设置有出光孔11，出光孔11内收纳有光学元件2，光学元件2通过弹片21与出光孔11紧固，结合图3和图4所示，弹片21呈C型设置，且在弹片21周向均布有安装孔，相邻安装孔之间向内凸设有用于压紧光学元件的压片211，以此对光学元件2形成稳定可靠的固定。
本实施例中，横向变形件811、812、813、814与纵向变形件821、822、823、824结构相同且长度相等，且均采用相同材质一体成型，以此在对光学元件进行调节时，使得纵向调节及横向调节用力均衡。此外，通过横向变形件811、812、813、814与纵向变形件821、822、823、824实现水平及竖直两个方向的位移，为了达到特定的行程，需要材料具有较大的屈服强度；结合图5所示，横向变形件及纵向变形件的相对两侧壁均设有凹陷部，本实施例凹陷部即采用椭圆弧结构设计，凹陷部优选椭圆弧结构设计，也可以采用其他形状，如圆弧形结构、双曲线结构等其他曲线形状均可以实现光学元件的精密调节，与直线型的结构形式相比，其精度高，与圆弧形结构相比，其具有较大的运动范围，所以椭圆弧的结构形式兼顾了运动范围和精度的优点，继而能够有效提升光学元件的调节精度及其稳定性。
本实施例中，横向变形件及纵向变形件的材料均选用Ti-Al-4v钛合金材料一体加工成型。Ti-Al-4v钛合金材料具有较好的加工能力和尺寸稳定性，由于二维调节机构与光学元件相连接，在温度变化较大的情况下，二维调节机构的热膨胀系数需要与光学元件材料的热膨胀系数匹配，以保证光学元件位置的稳定性。Ti-Al-4v钛合金材料参数如下表所示:
Figure PCTCN2018095488-appb-000001
可以通过优化设计椭圆弧的几何参数来得到二维调节机构所需要的行程范围和精度，结构几何参数如图5所示，主要包括长半轴a，短半轴b，最小厚度t和变形总长度L。变形部件的厚度变化时，调节机构变形部分受到的应力不会改变，所以不能通过横向变形件及纵向变形件的厚度来优化该二维调节结构。
在本实施例中二维调节机构要求的行程范围为0.5mm，通过优化设计及考虑到加工问题，横向变形件及纵向变形件的几何参数分别为a＝1.5mm，b＝0.6mm，t＝0.9mm，L＝5mm，当调节机构行程为0.5mm时，调节机构受到的最大vonmises应力为646MPa<892MPa,小于材料的屈服强度，如图6及图7所示，横向变形件及纵向变形件的中心点的位移为0.29mm，满足设计要求。
综合以上分析，本实施例中的二维调节机构的材料选择为钛合金，其具有较好的加工性能和尺寸稳定性，密度小，强度高和热膨胀系数低等优点，非常适合于做光学元件调节机构的特性要求。
本实施例还提供了一种出光模块，该出光模块包括上述光学元件2，作为优选，本实施例中的光学元件设置为出光透镜。
此外，本申请还提供了一种投影设备，包括上述调节机构。通过上述二维调节机构的设置，能够有效提升该投影设备的出光精度及出光效率，在此不做具体赘述。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具 体实施方式，这些方式都将落入本发明的保护范围之内。
