需要说明的是，第二主动齿轮30与第二从动齿轮50啮合或者分离，是指第二主动齿轮30运动时，第二从动齿轮50与第二主动齿轮30之间不会一直处于啮合的状态，而是在啮合状态和分离状态之间不断切换，即第二主动齿轮30与第二从动齿轮50之间处于部分啮合的状态。因此，第二从动齿轮50通过传动结构与第二天线阵列移相器110传动连接时，只能将驱动电机上的部分动力传递给第二天线阵列移相器110。
本申请实施例中，第一传动结构和第二传动结构主要通过齿轮传动的形式来实现，但并不限定第一传动结构和第二传动结构的实现形式，也可以采用齿轮传动、链传动或带传动中的一种或多种组合的方式进行等效变换。
本申请实施例中的天线齿轮箱传动机构主要应用于天线中，用于将驱动电机的动力传递到天线中的天线阵列移相器，本申请实施例中的天线包括第一天线阵列移相器100和第二天线阵列移相器110。其中，第一传动结构中的第一从动齿轮组用于与第一天线阵列移相器100传动连接，第二传动结构中的第二从动齿轮50用于与第二天线阵列移相器110传动连接。第一传动结构和第二传动结构为两个独立的传动结构，第一传动结构和第二传动结构的动力来源可以为同一个驱动电机。
本申请实施例中，通过设置第一传动结构和第二传动结构，第一传动结构中的第一从动齿轮组与天线上的第一天线阵列移相器100传动连接，第二传动结构中的第二从动齿轮50与天线上的第二天线阵列移相器110传动连接，分别实现对第一天线阵列移相器100和第二天线阵列移相器110的独立控制；通过将第一主动齿轮20和第二主动齿轮30与同一个驱动轴10传动连接，实现只布置一个驱动电机即可带动第一传动结构和第二传动结构独立运动，从而带动第一天线阵列移相器100和第二天线阵列移相器110进行独立的相位调节；通过设置第一主动齿轮20与第一从动齿轮组啮合，设置第二主动齿轮30与第二从动齿轮50啮合或分离，第一主动齿轮20可以将驱动轴10的全部动力传给第一从动齿轮组，而第二主动齿轮30可以在与第二从动齿轮50啮合时将驱动轴10的部分动力传给第二从动齿轮50，从而实现单驱动电机对第一天线阵列移相器100和第二阵列移相器独立的相位调节幅度的控制，即实现单驱动电机控制第一天线阵列移相器100和第二阵列移相器进行不同的相位调节。
本申请实施例中，第一从动齿轮组与第一天线阵列移相器100之间可以通过齿轮传动的方式实现动力传递，第二从动齿轮50与第二天线阵列移相器110之间也可以通过齿轮传动的方式实现动力传递。除齿轮传动的方式外，第一从动齿轮组与第一天线阵列移相器100之间，以及第二从动齿轮50与第二天线阵列移相器110之间也可以通过其他方式进行动力传递，如链传动、带传动，或者多种传动方式的组合，如齿轮传动与链传动的组合，或者齿轮传动与带传动的组合等等，本领域技术人员可以根据设计、布局等需求进行选择或组合。下面以齿轮传动为例，介绍本申请实施例中，第一从动齿轮组与第一天线阵列移相器100之间，以及第二从动齿轮50与第二天线阵列移相器110之间的动力传递形式。
如图1或图3所示，第一从动齿轮组中的第一从动齿轮40固定在第一传动轴60上，第一传动轴60上设置有与第一传动轴60不可相对旋转的输出齿轮80，即输出齿轮80可以是固定设置在第一传动轴60上。第一天线阵列移相器100上设置有与第一传动轴60上的输出齿轮80相啮合的轮齿，第一传动轴60上输出齿轮80的个数与第一天线阵列移相器100中移相器的数量相对应。当第一从动齿轮40转动时，第一从动齿轮40带动第一传动轴60转动，第一传动轴60带动其上的输出齿轮80转动，输出齿轮80与第一天线阵列移相器100啮合，而第一天线阵列移相器100是滑动连接在天线的支撑装置中的。因此，转动的输出齿轮80带动第一天线阵列移相器100前后滑动，实现相位调节。
如图1或图3所示，第二从动齿轮50固定在第二传动轴70上，第二传动轴70上设置有与第二传动轴70不可相对旋转的输出齿轮80，即输出齿轮80可以是固定设置在第二传动轴70上。第二天线阵列移相器110上设置有与第二传动轴70上的输出齿轮80相啮合的轮齿，第二传动轴70上输出齿轮80的个数与第二天线阵列移相器110中移相器的数量相对应。当第二从动齿轮50转动时，第二从动齿轮50带动第二传动轴70转动，第二传动轴70带动其上的输出齿轮80转动，输出齿轮80与第二天线阵列移相器110啮合，而第二天线阵列移相器110是滑动连接在天线的支撑装置中的。因此，转动的输出齿轮80带动第二天线阵列移相器110前后滑动，实现相位调节。
在本申请一实施例中，第二主动齿轮30上设置有部分轮齿。通过在第二主动齿轮 30上设置部分轮齿，使得第二主动齿轮30与第二从动齿轮50部分啮合，从而实现第二主动齿轮30在运动时，第二主动齿轮30与第二从动齿轮50实现啮合或分离。由于第二从动齿轮50是由第二主动齿轮30带动，其本身不具有动力，因此，一般在第二从动齿轮50上设置有完整的轮齿，以保证第二从动齿轮50能与第二主动齿轮30上设置有轮齿的部分进行啮合，实现动力的部分传递。
在本申请一实施例中，当驱动轴10沿预设方向转动时，第一从动齿轮40实现正向转动和反向转动，第二从动齿轮50实现正向转动或反向转动。
需要说明的是，当驱动轴10沿预设方向转动时，第一从动齿轮40实现正向转动和反向转动，是指第一从动齿轮40先进行正向转动，再进行反向转动；或者，第一从动齿轮40先进行反向转动，再进行正向转动。第二从动齿轮50实现正向转动或反向转动，是指当驱动轴10只沿一个方向转动时，第二从动齿轮50只会单向转动，该单向运动可以是正向运动也可以是反向运动。
本申请实施例通过设置第一从动齿轮40可以实现正向转动和反向转动，可以实现在驱动轴10沿一个方向转动时，对与第一传动结构相连的第一天线阵列移相器100进行双向调节，即第一天线阵列移相器100可以进行往复运动实现相位调节。通过设置第二从动齿轮50实现正向转动或反向转动，可以实现在驱动轴10沿一个方向转动时，对与第二传动结构相连的第二天线阵列移相器110进行单向调节，即第二天线阵列移相器110沿一个方向进行移动。
在本申请一实施例中，参考图2，图2为本申请实施例提供的天线齿轮箱传动机构的结构示意图之一。如图2所示，第一主动齿轮20和第二主动齿轮30均为齿条，第一主动齿轮20以及第二主动齿轮30同步运动且做直线运动。第一主动齿轮20的齿条长度大于第二主动齿轮30的齿条长度。
本申请实施例中，第一主动齿轮20和第二主动齿轮30均设置为齿条的形式，由于第一主动齿轮20和第二主动齿轮30均传动连接在驱动轴10上，驱动轴10转动时，可以带动第一主动齿轮20和第二主动齿轮30同步运动。而第一主动齿轮20和第二主动齿轮30均为齿条，因此，设置第一主动齿轮20和第二主动齿轮30的运动形式为直线运动，这样便于带动第一从动齿轮组和第二从动齿轮50进行运动。
通过设置第一主动齿轮20以及第二主动齿轮30均为齿条，当驱动轴10转动时，带动第一主动齿轮20和第二主动齿轮30同步进行直线运动，便于对第一天线阵列移相器100和第二天线阵列移相器110的运动进行控制。通过设置第一主动齿轮20的齿条长度大于第二主动齿轮30的齿条长度，可以实现对第一天线阵列移相器100的相位调节幅度，大于对第二天线阵列移相器110的的相位调节幅度，从而实现对不同天线阵列移相器的独立调节以及控制不同天线阵列移相器的调节幅度。
在本申请一实施例中，第一主动齿轮20与第二主动齿轮30一体成型。如图2所示，由于第一主动齿轮20和第二主动齿轮30均设置为齿条，且第一主动齿轮20和第二主动齿轮30均由驱动轴10带动，同步进行直线运动。因此，可以将第一主动齿轮20和第二主动齿轮30一体成型，这样设置可以提高生产第一主动齿轮20和第二主动齿轮30时的效率，有利于实现第一主动齿轮20与第二主动齿轮30的同步运动。同时，可以简化第一主动齿轮20和第二主动齿轮30与驱动轴10传动连接时的连接结 构，通过一个传动连接结构即可实现驱动轴10带动第一主动齿轮20和第二主动齿轮30同步进行运动，可以简化布局。
在本申请一实施例中，第一主动齿轮20和/或第二主动齿轮30上设置有连接块90，连接块90与驱动轴10螺纹连接。第一主动齿轮20和第二主动齿轮30与驱动轴10之间可以通过多种形式实现传动连接，如齿轮传动、链传动、带传动或螺纹传动等方式，由于本申请实施例中，第一主动齿轮20和第二主动齿轮30为齿条形式，因此，本实施例中采用螺纹传动的形式进行传动连接。具体的，在驱动轴10上设置有外螺纹，在第一主动齿轮20和/或第二主动齿轮30上设置有连接块90，连接块90上设置有与驱动轴10上的外螺纹相配合的内螺纹，螺纹的设计要求以驱动轴10转动时，连接块90可以沿驱动轴10的轴线进行前后移动为准。
当第一主动齿轮20和第二主动齿轮30设计为一体成型时，在第一主动齿轮20或第二主动齿轮30上设置一个连接块90，即可实现驱动轴10带动第一主动齿轮20和第二主动齿轮30沿着驱动轴10的轴线进行同步的直线运动。当第一主动齿轮20和第二主动齿轮30为独立的两个齿轮时，可以在第一主动齿轮20和第二主动齿轮30上分别设置一个连接块90，两个连接块90均与驱动轴10螺纹连接，也可以实现驱动轴10带动第一主动齿轮20和第二主动齿轮30沿着驱动轴10的轴线进行同步的直线运动。
在本申请一实施例中，第一主动齿轮20为矩形齿条，矩形齿条上设置有正向齿条201和反向齿条202；第二主动齿轮30上设置有正向齿条或反向齿条。
如图2所示，本申请实施例中，第一从动齿轮组包括一个第一从动齿轮40。第一主动齿轮20上设置有正向齿条201和反向齿条202，正向齿条201和反向齿条202分别位于矩形齿条内侧的上、下侧。第二主动齿轮30上只设置有正向齿条或者反向齿条，即只在一侧设置了齿条。第一主动齿轮20的齿条长度包括正向齿条201的长度和反向齿条202的齿条长度，由于第一主动齿轮20的齿条长度大于第二主动齿轮30的齿条长度，当第一主动齿轮20和第二主动齿轮30的运动行程与第一主动齿轮20的齿条长度相等时，在第二主动齿轮30的部分行程内，第二从动齿轮50处于停止状态。下面以第二主动齿轮30的齿条长度与第一主动齿轮20的正向齿条201的长度相等为例，对第一主动齿轮20和第一从动齿轮组、第二主动齿轮30和第二从动齿轮50的运动状态进行说明。
如图2所示，设定第一主动齿轮20靠近驱动轴10的方向为向下，第一主动齿轮20远离驱动轴10的方向为向上。当驱动轴10沿预设方向转动时，会带动与驱动轴10螺纹连接的连接块90沿着驱动轴10的轴线进行向下的直线运动，连接块90带动第一主动齿轮20和第二主动齿轮30沿着驱动轴10的轴线进行向下的直线运动，可以通过控制驱动轴10的转动，使得第一主动齿轮20和第二主动齿轮30的运动行程为第一主动齿轮20的齿条长度。在第一主动齿轮20向下运动的过程中，第一从动齿轮40先与正向齿条201啮合，带动第一传动轴60逆时针转动，然后第一从动齿轮40与反向齿条202啮合，带动第一传动轴60顺时针转动，第一传动轴60通过其上固定设置的输出齿轮80带动第一天线阵列移相器100进行上下移动，以实现天线的相位调节。与此同时，在第二主动齿轮30向下运动的过程中，第二从动齿轮50与第二主动齿轮30 上的轮齿进行啮合，第二主动齿轮30带动第二从动齿轮50顺时针转动或者逆时针转动，第二从动齿轮50带动第二传动轴70转动，第二传动轴70通过其上固定设置的输出齿轮80带动第二天线阵列移相器110进行移动，由于第二从动齿轮50沿一个方向转动，因此第二天线阵列移相器110只会沿一个方向移动。第二从动齿轮50的转动方向取决于第二主动齿轮30上设置的齿条是正向齿条还是反向齿条。
由于第二主动齿轮30的齿条长度与第一主动齿轮20的正向齿条201的长度相等，因此，当第二主动齿轮30的运动行程超过正向齿条201的长度时。此时，第二主动齿轮30上没有与第二从动齿轮50相啮合的轮齿，使得第二从动齿轮50处于停止状态，第二天线阵列移相器110也停止移动。而第一主动齿轮20与第一从动齿轮40一直处于啮合状态，会带动第一从动齿轮40一直转动，实现对第一天线阵列移相器100的位置调节。
需要说明的是，可以通过调节驱动轴10的转动方向，如调节驱动轴10沿与预设方向相反的方向转动，实现反向调节第一天线阵列移相器100和第二天线阵列移相器110的位置，从而实现反向调节天线的相位变化。
在本申请实施例中，通过将第一主动齿轮20设置为矩形齿条，有利于布置正向齿条201和反向齿条202，通过设置正向齿条201和反向齿条202，有利于实现第一从动齿轮40的正向转动和反向转动，从而实现对第一天线阵列移相器100的双向调节。通过在第二主动齿轮30上设置正向齿条或者反向齿条中的一种，可以实现在驱动轴10单向转动时，第二从动齿轮50也单向转动，从而实现对第二天线阵列移相器110的单向调节。
参考图3、图4和图5，图3为本申请实施例提供的天线齿轮箱传动机构的结构示意图之二以及应用场景示意图之二，图4为图2所示天线齿轮箱传动机构中第一传动结构的爆炸示意图，图5为图2所示天线齿轮箱传动机构中第二传动结构的爆炸示意图。如图3、图4和图5所示，在本申请一实施例中，第一从动齿轮组包括两个第一从动齿轮40，两个第一从动齿轮40关于第一主动齿轮20的中心对称设置，第一主动齿轮20上设置有半圈与第一从动齿轮40相啮合的轮齿。第二主动齿轮30上与第二从动齿轮50相啮合的轮齿的总长度小于第二主动齿轮30的周长。
在第一主动齿轮20上设置半圈与第一从动齿轮40相啮合的轮齿，然后将两个第一从动轮设置在第一主动齿轮20的两侧，并且两个第一从动轮关于第一主动轮的中心对称设置。当第一主动齿轮20转动一周时，第一主动齿轮20会分别与两个第一从动轮进行啮合，由于两个第一从动齿轮40是设置在第一主动齿轮20的两侧，因此两个第一从动齿轮40的转动方向是相反的。由于第二主动齿轮30上与第二从动齿轮50相啮合的轮齿的总长度小于第二主动齿轮30的周长，即第二主动齿轮30转动一周时，第二主动齿轮30与第二从动齿轮50部分啮合。
本申请实施例通过将两个第一从动齿轮40对称设置在第一主动齿轮20的两侧，并且在第一主动齿轮20上设置半圈轮齿，实现第一主动齿轮20只与其中一个第一从动齿轮40相啮合，并实现当第一主动齿轮20转一圈时，其中一个第一从动齿轮40正向转动，另一个第一从动齿轮40反向转动。通过设置第二主动齿轮30上与第二从动齿轮50相啮合的轮齿的总长度小于第二主动齿轮30的周长，即第二主动齿轮30 上设置有部分轮齿，第二从动齿轮50与第二主动齿轮30进行部分啮合，第二主动齿轮30转动一圈时，未设置轮齿的部分不能带动第二从动齿轮50转动，从而实现对第二天线阵列移相器110的相位调节幅度进行控制，且第二主动齿轮30与第二从动齿轮50部分啮合，第二主动齿轮30沿某个方向转动时，只能带动第二从动齿轮50单向转动。
本申请实施例中的天线齿轮箱传动机构主要应用于天线中，用于将驱动电机的动力传递到天线中的天线阵列移相器，本申请实施例中的天线包括第一天线阵列移相器100和第二天线阵列移相器110。其中，第一传动结构中的第一从动齿轮组用于与第一天线阵列移相器100传动连接，第二传动结构中的第二从动齿轮50用于与第二天线阵列移相器110传动连接。
在本申请一实施例中，第一主动齿轮20与驱动轴10以及第二主动齿轮30与驱动轴10均通过蜗轮蜗杆传动。通过蜗轮蜗杆传动的方式实现驱动轴10与第一主动齿轮20以及驱动轴10与第二主动齿轮30之间的传动，这样的布置方式有利于充分利用空间，同时改变动力的传动方向。
如图3、图4所示，在第一主动齿轮20上设置有第一涡轮21，在驱动轴10的一端设置有蜗杆120，第一主动齿轮20与驱动轴10通过蜗轮蜗杆传动连接。在第一主动齿轮20的上表面设置有半圈第一主动轮齿22，第一主动齿轮20的两侧分别设置有与第一主动轮齿22相啮合的第一从动齿轮40，两个第一从动齿轮40不可相对旋转的连接在第一传动轴60上，可以将两个第一从动齿轮40均固定设置在第一传动轴60上。第一传动轴60上设置有一组或者多组不可相对旋转的输出齿轮80，输出齿轮80与第一天线阵列移相器100啮合，输出齿轮80的数量与第一天线阵列移相器100上阵列移相器的数量相关。
当驱动轴10沿预设方向转动时，驱动轴10通过蜗轮蜗杆结构带动第一主动齿轮20转动，第一主动齿轮20转动一圈的过程中，会带动两个第一从动齿轮40转动，两个第一从动齿轮40的转动方向相反。由于两个第一从动齿轮40均固定在第一传动轴60上，因此，在第一主动齿轮20转动一圈的过程中，第一传动轴60会先正转再反转(或者先反转再正转)，第一传动轴60上的输出齿轮80带动第一天线阵列移相器100进行移动。在第一主动齿轮20转动一圈的过程中，第一天线阵列移相器100会进行往复运动，实现对天线的相位进行调节。
如图3、图5所示，在第二主动齿轮30上设置有第二涡轮31，在驱动轴10的另一端设置有蜗杆120，第二主动齿轮30与驱动轴10通过蜗轮蜗杆传动连接。在第二主动齿轮30的上表面设置有部分第二主动轮齿32，本申请实施例中以在第二主动齿轮30的上表面设置有半圈第二主动轮齿32为例进行说明。第二主动齿轮30的一侧设置有与第二主动轮齿32相啮合的第二从动齿轮50，第二从动齿轮50固定连接在第二传动轴70上。第二传动轴70上设置有一组或者多组不可相对旋转的输出齿轮80，输出齿轮80与第二天线阵列移相器110啮合，输出齿轮80的数量与第二天线阵列移相器110上阵列移相器的数量相关。
当驱动轴10沿预设方向转动时，驱动轴10通过蜗轮蜗杆结构带动第二主动齿轮30转动。由于第二主动齿轮30的上表面只设置有半圈第二主动轮齿32，因此第二主 动齿轮30转动一圈时，在其中半圈的转动过程中，第二主动齿轮30与第二从动齿轮50处于啮合状态，带动第二从动齿轮50转动，第二从动齿轮50带动第二传动轴70转动，第二传动轴70上设置的输出齿轮80带动第二天线阵列移相器110进行移动。由于只设置有一个第二传动齿轮，因此第二传动轴70的方向只与驱动轴10的转动方向相关，即在驱动轴10方向确定时，第二传动轴70的转动方向确定，第二天线阵列移相器110的移动方向确定，且为单向移动。在另外半圈的转动过程中，第二主动齿轮30无轮齿与第二从动齿轮50啮合，第二主动齿轮30与第二从动齿轮50处于分离状态，第二从动齿轮50停止转动，第二天线阵列移相器110也处于停止状态。因此，第二天线阵列移相器110的位移情况与第二主动齿轮30上设置的第二主动轮齿32的长度有关。
本申请实施例中，可以通过调节驱动轴10的转动方向，例如调节驱动轴10沿与预设方向相反的方向转动，即可以调节第一天线阵列移相器100和第二天线阵列移相器110进行反向移动。
本申请实施例中，为了固定第一传动结构和第二传动结构，还设置有相应的固定座。具体的，设置有第一上固定座131和第一下固定座132用于固定第一传动结构，设置有第二上固定座141和第二下固定座142用于固定第二传动结构，第一上固定座131和第一下固定座132之间可以采用螺栓结构进行连接，第二上固定座141和第二下固定座142之间可以采用螺栓结构进行连接。第一上固定座131和第一下固定座132的内部结构与第一传动结构相适配，第二上固定座141和第二下固定座142的内部结构与第二传动结构相适配。
在本申请一实施例中，第一主动齿轮20与第二主动齿轮30的规格相同。通过将第一主动齿轮20和第二主动齿轮30设置为规格相同，方便布局，且容易对阵列移相器的调节幅度进行控制。
在本申请一实施例中，上第一从动齿轮40和第二从动齿轮50均为锥齿轮。将第一从动齿轮40和第二从动齿轮50设置为锥齿轮，可以更好地使第一从动齿轮40与第一主动齿轮20上的第一主动轮齿22进行配合，以及更好地使第二从动齿轮50与第二主动齿轮30上的第二主动轮齿32进行配合，锥齿轮可以改变动力的传动方向，便于根据驱动轴10和阵列移相器的位置进行结构布局。
基于同一发明构思，本申请一实施例提供一种天线。该天线包括第一天线阵列移相器100、第二天线阵列移相器110以及如任意一实施例所提供的天线齿轮箱传动机构，第一天线阵列移相器100与第一从动齿轮组传动连接，第二天线阵列移相器110与第二从动齿轮50传动连接。第一天线阵列移相器100与第一从动齿轮组传动连接，以及第二天线阵列移相器110与第二从动齿轮50传动的传动连接结构可以参照前述实施例中所介绍的内容。上述天线具有与前述实施例提供的天线齿轮箱传动机构相同的技术效果，此处不再赘述。
本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。
尽管已描述了本申请实施例的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例做出另外的变更和修改。所以，所附权利要求意欲 解释为包括优选实施例以及落入本申请实施例范围的所有变更和修改。
