Description

一种具有减速器的舞台灯 技术领域
本发明涉及舞台灯技术领域，更具体地，涉及一种具有减速器的舞台灯。
背景技术
舞台灯在工作过程中，经常需要旋转灯头，调整光束射出方向。现有舞台灯的灯头的枢接轴驱动机构都是通过同步带与枢接轴连接传动，并且通过同步带拉动灯头的旋转，同步带一般为橡胶或者塑料材质，这种传动过程中同步带除起到传动的功能外还需起到受力的作用，特别是灯具侧挂时同步带的受力更大，容易造成同步皮带断裂，且由于同步皮带受力也有一定的弹性拉伸，因此往往会造成灯具的扫描定位不准确，影响产品的稳定性。
发明内容
本发明为克服上述现有技术所述的至少一种缺陷，提供一种具有减速器的舞台灯，使得扫描系统更准确，可用更小的电机，空间占用也更小，效果更稳定。
为解决上述技术问题，本发明采用的技术方案是：一种具有减速器的舞台灯，包括灯头、支撑臂以及底箱，所述灯头通过枢接轴枢接于所述支撑臂，所述支撑臂通过枢接轴枢接于所述底箱，所述灯头及/或所述支撑臂的所述枢接轴通过减速器与驱动机构的驱动轴连接。
所述灯头及/或所述支撑臂的所述枢接轴通过减速器与所述驱动机构的所述驱动轴连接，从而实现利用所述减速器内的传动件进行传动，避免采用同步带，传动件不会变形导致扫描定位不准确或者断裂损坏，产品性能更稳定。
进一步地，所述驱动轴与所述枢接轴平行设置或者垂直设置。根据所述减速器安装位置的空间大小来定，自由选择，以合理安排空间。
进一步地，所述枢接轴沿长度方向具有用于过线或者流通冷却介质的贯穿孔，所述减速器与所述枢接轴连接的旋转轴对应设置有通孔。通过设置所述贯穿孔与所述通孔，可以便于所述灯头及/或所述支撑臂内的线缆、冷却介质穿过，使所述灯头及/或所述支撑臂可以顺利旋转。
进一步地，所述减速器与所述枢接轴之间通过联轴法兰连接。所述联轴法兰可以在所述减速器的旋转轴、所述枢接轴不经过特殊设计的情况下，将普通的所述旋转轴与普通的所述枢接轴连接起来，元件的通用性更强。
进一步地，所述联轴法兰包括与所述枢接轴连接的固定盘以及与所述减速器的旋转轴连接的固定筒，所述固定盘位于所述固定筒端部。由于所述枢接轴一般直径较大，而所述减速器的所述旋转轴较小，所以将所述联轴法兰设计为所述固定盘加所述固定筒的结构，可以解决所述枢接轴与所述旋转轴尺寸不匹配的问题，以将两者顺利连接起来。
进一步地，所述联轴法兰包括连接筒，所述连接筒的侧壁沿长度方向设置有第一连接孔以通过螺钉与所述枢接轴连接固定，所述连接筒的侧壁在与长度方向相垂直的方向上设置有第二连接孔以通过螺钉与所述减速器的旋转轴连接固定。当所述旋转轴与所述枢接轴直径相同或者相近时，可以直接通过所述连接筒将两者连接起来，且可以保证所述联轴法兰体积较小。
进一步地，还包括对所述减速器进行支撑的支撑架。所述减速器安装于所述支撑架上，所述支撑架固定于所述灯头或者所述支撑臂，便于将所述减速器固定。
进一步地，所述减速器为齿轮减速器。即所述减速器内部的传动件均为齿轮。
进一步地，所述枢接轴与所述减速器的旋转轴连接为一体。即直接将所述减速器的旋转轴作为所述灯头及/或所述支撑臂的枢接轴，减少了不必要的连接件，结构更简单。
进一步地，所述灯头的所述驱动机构、所述支撑臂述的所述驱动机构均位于所述支撑臂内。腾出所述灯头、所述底箱内部的空间，便于安装其它元件或者散热。
进一步地，所述灯头述的所述驱动机构位于所述灯头内，所述支撑臂的所述驱动机构位于所述底箱内。腾出所述支撑臂内部的空间，便于安装其它元件或者散热。

在本发明优选地实施例中，所述减速器(500)与所述枢接轴(400)之间通过联轴法兰(700)连接。所述联轴法兰(700)可以在所述减速器(500)的旋转轴(510)、所述枢接轴(400)不经过特殊设计的情况下，将普通的所述旋转轴(510)与普通的所述枢接轴(400)连接起来，元件的通用性更强。所述联轴法兰(700)的形状可以根据需要自由选择，只要可以将所述旋转轴(510)与所述枢接轴(400)连接起来进行传动即可。
在本发明优选地实施例中，所述联轴法兰(700)包括与所述枢接轴(400)连接的固定盘(711)以及与所述减速器(500)的旋转轴(510)连接的固定筒(712)，所述固定盘(711) 位于所述固定筒(712)端部。所述固定盘(711)在垂直于盘的方向上设置锁紧孔(713)，所述固定筒(712)在垂直于其中心线的方向上设置有锁紧孔(713)，从而通过螺钉分别将所述固定盘(711)与所述枢接轴(400)连接，所述旋转轴(510)与所述固定筒(712)连接。由于所述枢接轴(400)一般直径较大，而所述减速器(500)的所述旋转轴(510)较小，所以将所述联轴法兰(700)设计为所述固定盘(711)加所述固定筒(712)的结构，可以解决所述枢接轴(400)与所述旋转轴(510)尺寸不匹配的问题，以将两者顺利连接起来
在本发明优选地实施例中，还包括对所述减速器(500)进行支撑的支撑架(520)。所述减速器(500)安装于所述支撑架(520)上，所述支撑架(520)固定于所述灯头(100)或者所述支撑臂(200)，便于将所述减速器(500)固定。优选地，所述支撑架(520)呈U型板状，两侧板用于与支撑臂(200)的连接，顶板用于安装所述减速器(500)。
在本发明优选地实施例中，所述减速器(500)为齿轮减速器。即所述减速器(500)内部的传动件均为齿轮。在其他实施例中，所述减速器(500)也可以为蜗杆减速器和行星减速器以及由齿轮减速器、蜗杆减速器和行星减速器互相组合起来的减速器。
需要注意的是，所述减速器(500)与所述驱动机构(600)的驱动轴(610)或者所述枢接轴(400)之间，可以适量采用同步带传动，在牺牲一定的精度情况下，满足各种具体应用需求；必要的时候，所述减速器(500)内部也可以设置同步带。
在本发明优选地实施例中，所述灯头(100)的所述驱动机构(600)、所述支撑臂(200)述的所述驱动机构(600)均位于所述支撑臂(200)内。腾出所述灯头(100)、所述底箱(300)内部的空间，便于安装其它元件或者散热。
在其它实施例中，所述灯头(100)述的所述驱动机构(600)位于所述灯头(100)内，所述支撑臂(200)的所述驱动机构(600)位于所述底箱(300)内。腾出所述支撑臂(200)内部的空间，便于安装其它元件或者散热。
如图2，为本发明第二实施例，提供一种具有减速器(500)的舞台灯，包括灯头(100)、支撑臂(200)以及底箱(300)，所述灯头(100)通过枢接轴(400)枢接于所述支撑臂(200)，所述支撑臂(200)通过枢接轴(400)枢接于所述底箱(300)，所述灯头(100)在所述支撑臂(200)上绕第一方向旋转，所述支撑臂(200)转动以带动所述灯头(100)绕第二方向旋转，所述灯头(100)及/或所述支撑臂(200)的所述枢接轴(400)通过减速器(500)与驱动机构(600)的驱动轴(610)连接，可以仅其中一个所述枢接轴(400)通过减速器(500)与驱动机构(600)的驱动轴(610)连接，也可以是所述灯头(100)及所述支撑臂(200) 的所述枢接轴(400)通过减速器(500)与驱动机构(600)的驱动轴(610)连接，以提高所述灯头(100)在对应方向上的旋转精度和稳定性。
在本发明优选地实施例中，所述驱动轴(610)与所述枢接轴(400)平行设置。所述驱动机构(600)可以位于所述减速器(500)靠近所述枢接轴(400)一侧，也可以位于所述减速器(500)远离所述枢接轴(400)一侧，只要所述驱动轴(610)与所述枢接轴(400)平行设置即可。具体根据所述减速器(500)安装位置的空间大小来定，自由选择，以合理安排空间。优选地，所述驱动机构(600)可以位于所述减速器(500)远离所述枢接轴(400)一侧。
在本发明优选地实施例中，所述枢接轴(400)沿长度方向具有用于过线或者流通冷却介质的贯穿孔(410)，所述减速器(500)与所述枢接轴(400)连接的旋转轴(510)对应设置有通孔(511)。通过设置所述贯穿孔(410)与所述通孔(511)，可以便于所述灯头(100)及/或所述支撑臂(200)内的线缆、冷却介质穿过，使所述灯头(100)及/或所述支撑臂(200)可以顺利旋转。可选地，所述枢接轴(400)、所述贯穿孔(410)中心线重合。可选地，所述枢接轴(400)、所述贯穿孔(410)均为圆孔。
在本发明优选地实施例中，所述枢接轴(400)与所述减速器(500)的旋转轴(510)连接为一体。即直接将所述减速器(500)的旋转轴(510)作为所述灯头(100)及/或所述支撑臂(200)的枢接轴(400)，减少了联轴法兰(700)，结构更简单。可选地，连接为一体的所述枢接轴(400)与所述减速器(500)的旋转轴(510)均沿长度方向贯穿，以便于所述灯头(100)及/或所述支撑臂(200)内的线缆、冷却介质穿过。
如图3，为本发明第三实施例，与第一实施例的区别在于，所述联轴法兰(700)包括连接筒(720)，所述连接筒(720)的侧壁沿长度方向设置有第一连接孔(721)以通过螺钉与所述枢接轴(400)连接固定，所述连接筒(720)的侧壁在与长度方向相垂直的方向上设置有第二连接孔(722)以通过螺钉与所述减速器(500)的旋转轴(510)连接固定。当所述旋转轴(510)与所述枢接轴(400)直径相同或者相近时，尤其是需要在所述减速器(500)的所述旋转轴(510)上设置通孔(511)时，可以直接通过所述连接筒(720)将两者连接起来，且可以保证所述联轴法兰(700)体积较小。
