 本发明的最佳实施方式
下面通过各个具体实施方式结合附图对本实用新型作进一步详细说明。
参照图1至图3，作为本实用新型所提供的镜片模组的一个实施例，镜片模组100包括支座110、滑块120、镜片组件130和滑块调节件170。滑块120滑动固定于支座110上。滑块调节件170用于调节滑块120沿第一方向正向滑动或反向滑动，该第一方向垂直于支座的轴向，例如，参照图1，轴向为X轴方向，第一方向为Y轴方向，第一方向的正向和反向可以分别是Y+和Y-的指向，也可以分别是Y-和Y+的指向。需要说明的是，支座的轴向和第一方向可以根据为调节镜片组件在镜片模组中的位置而具体设定。滑块120沿第一方向以外的方向保持固定。镜片组件130弹性固定于支座110上，镜片组件130能够沿支座110的比如X+指向的轴向远离支座110移动，镜片组件130沿轴向以外的方向保持固定，在远离支座110移动过程中，驱使镜片组件130返回的回弹力逐渐加大，可知的是，当镜片组件130沿支座110的比如X-指向的轴向接近支座110移动时，相应的，上述驱使镜片组件130返回的回弹力逐渐减小；除了镜片组件130在上述轴向方向上最接近支座的位置可以不受到回弹力作用之外，镜片组件130在上述轴向的其它位置，都始终受到返回的回弹力或者说是接近支座的回弹力作用,但较佳的是镜片组件130一直受到回弹力作用。滑块120的第一侧面与支座110滑动固定，滑块120在与第一侧面相对的第二侧面上设置有第一引导件，镜片组件130在面对滑块120的第三侧面上设置有与第一引导件相配合的第二引导件。第一引导件具有沿第一方向的正向延伸而逐渐远离第二侧面的第一突出面，第二引导件具有沿第一方向的反向延伸而逐渐远离第三侧面的第二突出面，滑块120与镜片组件130通过第一突出面和第二突出面相抵接。也就是说，第一引导件的第一突出面和第二引导件的第二突出面朝向彼此突出以保持两者相互配合作用。
本实施例的镜片模组100利用滑块调节件170对滑块120的位置调节，使得镜片组件130可通过滑块120的第一引导件与镜片组件130的第二引导件的相对运动产生接近或远离支座110的位移，并且位移稳定性高，从而容易获得透镜对光线进行光学处理的最佳位置，并且，滑块调节件170的采用提高了调节镜片组件130位移的准确度。
作为对镜片模组所具有的一种具体结构的详细说明，参照图1至图3，支座110具有第一开孔111、第一连接孔和第二连接孔，第一开孔111的中心轴线被作为上述的轴向，滑块120具有第二开孔121和第三连接孔122，该第三连接孔122与第一连接孔相对应，滑块120具有第一侧面H1和第二侧面H2，第一侧面H1与支座110滑动固定，在第二侧面H2上设有第一引导件123。镜片组件130具有支架131和固定在支架131上的镜片132，镜片132位于第一开孔111和第二开孔121的透光区域之内，支架131上设有与透光区域对应的透过部分133，该透光区域是指第一开孔111和第二开孔121所具有的空间范围，该空间范围能够保证激光、LED、荧光等光线无阻碍地经过第一开孔111和第二开孔121再入射于镜片组件130并进一步从透过部分133出射或经过透过部分133入射于镜片组件130再经过第二开孔121和第一开孔111并进一步出射。镜片模组100还包括第一弹性件，第二引导件135在第一弹性件的回弹力作用下保持朝着第一引导件123方向与第一引导件123相抵接。支架131上设有与第二连接孔对应的第四连接孔134和与第一引导件123对应设置的第二引导件135，该第二引导件135设置在镜片组件130面对滑块120的第三侧面H3上。镜片模组100还包括第一螺纹连接件150和第二螺纹连接件160，滑块120通过第一螺纹连接件150与第一连接孔固定连接来与支座110相连接，镜片组件130通过第二螺纹连接件160与第二连接孔固定连接来与支座110相连接，支座110、滑块120和镜片组件130沿支座110的轴向依次布置，且较优的是，第二开孔121和第四连接孔134的中心轴线分别与上述第一开孔111的中心轴线相互重合。镜片模组100还包括滑块调节件170，通过调节滑块调节件170可在沿第一方向驱动滑块120运动的过程中使第一引导件123和第二引导件135相对运动，并且第三连接孔122相对于第一连接孔可相对运动，也就是说，在滑块调节件170的驱动下，滑块120可以相对于支座110运动，同时，第四连接孔134相对于第二连接孔可相对运动，也就是说，在滑块120的运动作用下，镜片组件130可以相对于支座110运动，从而，镜片组件130可以产生沿垂直于第一方向接近或远离支座110的位移，需要指出的是，滑块120可以设置成容纳于支座110之中，也可以是将支座110设置成容纳于滑块120之中，只要两者装配在一起之后，它们之间具有可以相对运动的间隙。对于上述的第一弹性件，只要该第一弹性件能提供保持第二引导件135朝向第一引导件123方向与第一引导件123相抵接的作用力，以实现滑块120在滑块调节件170的作用下在第一方向上的运动能带动镜片组件130在支座110的轴向上的位移，那么该第一弹性件就都在本实用新型的保护范围之内，对于第一弹性件的一些具体实施方式将在以下作更进一步的说明。
更进一步来说，上述第一引导件优选的是设为至少一对，该至少一对第一引导件相对于上述第一方向对称设置，因而，第二引导件也优选的是设为至少一对并与第一引导件对应设置，从而保证滑块与镜片模组相对运动的稳定。
参照图1至图3，作为第一连接孔和第二连接孔的一种具体实施方式，支座110具有支板114，第一连接孔和第二连接孔分别对应地设置在支板114的第一连接柱112和第二连接柱113上，相应的，第一连接柱112穿过第三连接孔122并与第一螺纹连接件150固定连接，第二螺纹连接件160穿过第四连接孔134和滑块120并与第二连接柱113固定连接，具体来说，第一连接孔和第二连接孔分别为第一连接柱112和第二连接柱113中贯通的或截止的内螺纹孔，第一螺纹连接件150的外螺纹与第一连接孔螺纹固定连接，第二螺纹连接件160的外螺纹与第二连接孔螺纹固定连接，通过如此设置，第一螺纹连接件与第三连接孔122之间为间隙配合，两者之间的间隙满足允许滑块120相对于支座110在第一方向上位移的位移量，第二连接件可以通过穿过第二开孔121或者同时穿过第二开孔121和第五连接件（以下将作详细描述）来穿过滑块120，并且，第二螺纹连接件160与第四连接孔134之间为间隙配合，两者之间的间隙满足允许镜片模组100相对于支座110在支座的轴向上位移的位移量。
作为第一连接孔和第二连接孔的另一种具体实施方式，支座110具有支板114，第一连接孔和第二连接孔分别设置在该支板114之中，相应的，第一螺纹连接件150穿过第三连接孔122并于第一连接孔固定连接，第二螺纹连接件160经过第四连接孔134和滑块120并与第二连接孔固定连接，具体来说，第一连接孔和第二连接孔为内螺纹孔，第三连接孔122为光孔，第一螺纹连接件150的自由端处的外螺纹穿过第三连接孔122与第一连接孔固定连接，第一螺纹连接件150和第三连接孔122之间为间隙配合，两者之间的间隙满足允许滑块120相对于支座110在第一方向上位移的位移量，第二连接柱113与第四连接孔134之间为间隙配合，两者之间的间隙满足允许镜片模组100相对于支座110在支座的轴向上位移的位移量。
参照图1和图2，作为滑块调节件170的一种具体实施方式，滑块调节件170可以是与在第一方向上位于支座110的端部中心的第一螺纹孔（未图示）螺纹配合并与滑块120的第一自由端124相抵的螺纹调节件170，此种情况下，为了避免螺纹调节件170对第一自由端124的磨损，螺纹调节件170优选采用螺栓或螺柱。滑块调节件170也可以是穿过在上述第一方向上位于支座110的端部中心的空心圆柱形开口并与滑块120的第一自由端124处的第二螺纹孔螺纹配合的螺纹调节件170，此种情况下，螺纹调节件170可以采用螺丝、螺栓、螺钉或螺柱等。上述端部包括支座110在第一方向上的两个端部中的任意一个，第一自由端根据该任意一个端部做对应设置。滑块120与支座110之间具有第一最大预设间隙，该第一最大预设间隙为允许滑块120相对于支座110在第一方向上的最大相对运动距离。在螺纹调节件170与第一螺纹孔或第二螺纹孔的旋转配合而产生线性运动的作用力下，滑块120可以被螺纹调节件170所驱动而在第一最大预设间隙内运动。由于采用螺纹调节件170，不仅对于滑块120的驱动可以平稳，而且可以通过螺纹调节件170旋转圈数或角度准确地调节滑块120的位移量。为了达到对滑块120提供最佳的驱动力，防止滑块120运动时的晃动，滑块调节件170较优的是穿过位于支座110在第一方向（比如图1中Y轴所示的第一方向）上底处端部115的中心而与滑块120的中部相配合，这样的话，滑块120通过其自身的自重压向滑块调节件170，使得滑块120的运动至最佳位置后被更稳定地固定。
为了进一步提高螺纹调节件170对滑块120驱动的平稳度和准确度，镜片模组100还具有第二弹性件，以螺纹调节件170为经过上述支座110底处端部115的中心的开口并与滑块120的第一自由端124处的第二螺纹孔螺纹配合为例，该第二弹性件是在滑块120的第一自由端124和支座110底端之间并各等间距地位于螺纹调节件170的每一侧的至少一个弹簧180，对于这一种情况，通过将作为第二弹性件的弹簧180压缩地布置在滑块120的第一自由端124和支座110底端之间，弹簧180不仅可以起到对滑块120的一定支撑作用，而且，还可以给螺纹调节件170提供预紧力，从而便于保持滑块120相对于支座110的位置。另外，该第二弹性件也可以是在滑块120的第二自由端125和支座110的顶处端部之间被压缩并且相对于螺纹调节件170的轴线对称设置的至少两个第二弹性件，对于该另一种情况，第二弹性件同样可以起到支撑滑块120及提供预紧力的作用。此外，镜片模组100也可以同时设置上述两种情况所述的第二弹性件，第二弹性件所起的作用与上述类似，故不再赘述，但能对滑块120更好地支撑，只是成本会相对有所增加。需要说明的是，对于滑块调节件170是与在第一方向上位于支座110的端部中心的第一螺纹孔螺纹配合并与滑块120的第一自由端124相抵的螺纹调节件170的情形，第二弹性件也可做相适应的设置，在此不再赘述。另外，第二弹性件可以采用弹簧、拉簧、压簧和压片中的一种或多种。
参照图2和图3，以下进一步对第二螺纹连接件160作详细的说明，第二螺纹连接件160较佳的是一种具有螺纹段160A和光滑段160B的螺纹部件，该螺纹段160A与第二连接孔的内螺纹固定连接，在本实施例中，第一弹性件为弹簧140，弹簧140套设在光滑段160B的外周，弹簧140至少部分的位于第四连接孔134之中并被压缩在支架131和螺纹部件的头部160C之间，支架131在滑块120的作用下可以沿支座110的轴向压缩或释放弹簧，从而使镜片组件130产生接近或远离支座110的位移。在本实施例中，上述布置在第四连接孔134之中的弹簧140始终对镜片组件130施加朝向滑块120的作用力，从而保持第二引导件135与第一引导件123相抵接，其结构简单，并便于装配。更具体来说，螺纹部件采用等高螺丝或等高螺栓，如此，螺纹部件不仅容易获得且成本较低。另外，第一弹性件还可以为拉簧、压簧或压片。
为了达到第一弹性件始终对镜片组件130施加朝向滑块120的作用力使得第二引导件135与第一引导件123保持相抵接，第一弹性件固定方式还可以是一端固定在支架131上，另一端固定在滑块120或支座110上，第一弹性件优选是采用多个，并且均布在支座110的外架的外围或外架的内部，从而提供均匀的作用力。
参照图1、图6和图7，以下对第一引导件123和第二引导件135做详细说明，作为优选的实施方式，第一引导件123和第二引导件135分别设为至少一对第一楔形突起和至少一对第二楔形突起，第一楔形突起和第二楔形突起分别具有相互配合并可相对滑动的第一突出面和第二突出面，第一突出面和第二突出面为倾斜表面，第一楔形突起的第一突出面与第二楔形突起的第二突出面相互平行，第一突出面在第一方向Y轴的Y+指向上的高度沿支座110的轴向X轴的X+指向逐渐增大，相应的，第二突出面在第一方向Y轴的Y+指向上的高度沿支座110的轴向X轴的X-指向逐渐增大，因此，当滑块调节件170驱动滑块120沿第一方向Y轴的Y+指向运动时，第三连接孔122相对于第一连接孔沿Y+指向运动，并且在第一楔形突起沿Y+指向运动的同时，第二突出面在第一弹性件的作用下沿着第一突出面沿支座110的轴向X轴的X-指向运动，因此，镜片组件130产生沿X-指向接近支座110的位移，请参照图6所示，当第一楔形突起沿Y+指向运动直至无法运动时，此时，镜片模组100的镜片组件130最接近支座110。对于当滑块调节件170驱动滑块120沿第一方向Y轴的Y-指向运动时，其原理与滑块120沿Y+指向运动时的相同，在此不再赘述，因此，请参照图7所示，当第一楔形突起沿Y-指向运动直至无法运动时，此时，镜片模组100的镜片组件130最远离支座110，对于图7，图7所表示的镜片模组未采用弹簧180，可知的是，若镜片模组采用了弹簧180，则相比于图6，图7中的滑块120的第一自由端和支座110的底处端部之间将具有间隙，并且位于该间隙之间的弹簧180被进一步的压缩了。另外，对于第一突出面和第二突出面的倾斜角度和倾斜方向可以根据实际需要而定，在此不做具体限定。此外，比如每个第一突出面和第二突出面也可以包括两对以上小突台所具有的光滑子倾斜表面，第一突出面所包括的子倾斜表面和第二突出面所包括的子倾斜表面分别位于一个倾斜表面上，并且两倾斜表面相互平行。又比如，进一步参照图4，第一引导件223和第二引导件235也可以为相互配合的具有倾斜表面的三角形突起。还比如，进一步参照图5，第一引导件323和第二引导件335可以为具有圆周面的半圆柱形突起。因此，只要滑块120的第一引导件在滑块调节件170第一方向驱动下能与镜片模组100的第二引导件产生相对运动使得镜片组件130产生沿与第一方向相垂直的支座110的轴向接近或远离支座110，则该第一引导件和第二引导件均在本实用新型的保护范围之内。
参照图1，作为另一实施例的镜片模组100的具体结构，滑块120为具有第二开孔121的大致长方体，支座110具有容纳滑块120的凹部116，上述一对第一楔形突起分别沿长方体的一对长边126延伸并以平行于长边126的第一中心线为中心对称分布，在临近长方体的一对短边127处以平行于短边127的第二中心线为中心对称分布两对第三连接孔122，第三连接孔122为腰形孔，支架131为中空圆柱体，镜片132固定在中空圆柱体中，在中空圆柱体远离支座110的端部设有一环形凸缘131A，凸缘131A具有一对凸台131B和一对上述第二楔形突起，各凸台131B中设有一第四连接孔134，凸台131B和第二楔形突起相间地均布在凸缘131A上。 因此，腰形孔可在其所具有的形状引导下相对于第一螺纹连接件150沿第一方向Y轴相对运动，并且由于具有第四连接孔134的凸台131B和第二楔形突起相间地均布在环形凸缘131A上，可以保证滑块调节件170调节滑块120时，滑块120与镜片组件130所产生的相对运动更平稳和准确。
作为对上述第一弹性件具体实施方式的进一步举例，在上述镜片模组100的具体结构的基础上，采用至少两个第一弹性件（未图示），该至少两个第一弹性件相对于中空圆柱体的中心轴线均匀布置，第一弹性件的一端固定在凸缘131A上，第一弹性件的另一端固定在滑块120上。该第一弹性件可以为被拉伸状态的弹簧或拉簧，凸缘131A和滑块120上对应的设有与弹簧或拉簧两端固定配合的固定孔。另外，第一弹性件可以同时包括上述至少部分的位于第四连接孔134之中的作为第一弹性件的弹簧140和上述相对于中空圆柱体的中心轴线均匀布置的至少两个第一弹性件。
更进一步的，上述腰形孔可相对于第一螺纹连接件150产生位移，第一螺纹连接件150与腰形孔之间具有第二最大预设间隙，并且，在第一方向上，滑块120与支座110之间具有允许滑块相对于支座相对运动的第一最大预设间隙，第一最大预设间隙≥第二最大预设间隙，因此，各腰形孔在第一方向Y的延伸长度可以限定允许腰形孔相对于第一连接孔的运动空间从而满足滑块120相对于支座110在第一方向Y上位移的最大位移量。
作为进一步的改进，滑块120还包括一对第五连接孔128，第五连接孔128与第二开孔121连通，第五连接孔128可相对于第二螺纹连接件160产生位移，一对第五连接孔128以第二中心线为中心对称分布，在第一方向上，对于临近长方体的同一短边127的第五连接孔128和腰形孔，第五连接孔128的与第二中心线的最大距离≥腰形孔与第二中心线的最大距离。如此，不仅第五连接孔128与第二螺纹连接件160相互配合能使滑块120的运动更平稳，而且，各第五连接孔128在第一方向Y的延伸长度可以限定允许第五连接孔128相对于第二螺纹连接件160的运动空间从而满足滑块120相对于支座110在第一方向Y上位移的最大位移量。
