具体实施方式
下面通过实施例，并结合附图，对本公开内容的技术方案作进一步具体的说明。在说明书中，相同或相似的附图标号指示相同或相似的部件。下述参照附图对本公开内容的实施方式的说明旨在对本公开内容的总体发明构思进行解释，而不应当理解为对本公开的一种限制。
本文所使用的术语"包括"、"包含"及类似术语应该被理解为是开放性的术语，即"包括/包含但不限于"，表示还可以包括其他内容。术语"基于"是"至少部分地基于"。术语"一个实施例"表示"至少一个实施例"；术语"另一实 施例"表示"至少一个另外的实施例"，等等。
本公开内容的实施例主要关注以下技术问题：如何减小传动装置的占用空间、提高传动控制精度、降低制造成本。
为了解决上述问题，本文所公开的用于天线的传动装置包括机壳、一个或多个输出单元、以及一个或多个输入单元，使得输入单元与相应的输出单元的齿条啮合匹配，从而驱动输出单元线性运动。
如图1、图3以及图4所示，本文所公开的用于天线的传动装置包括：机壳100、至少一个输出单元200、以及至少一个输入单元。其中，输出单元200滑动设置于机壳100，并且输出单元200至少包括齿条210；输入单元至少部分设置在机壳100内，并与输出单元200的齿条210啮合匹配，用于驱动输出单元200线性运动。
具体地，如图1、图3以及图4所示，用于天线的传动装置包括多个输出单元200和多个输入单元，使得每个输出单元200都与相应的输入单元啮合匹配，并受该输入单元的控制。
另外，输出单元200还包括组配结构220，组配结构220与齿条210耦接。在实际使用中，组配结构220与齿条210可以根据设计需要一体地形成，也可以经由连接件将二者耦接在一起。
如图1、图2、图4以及图5所示，输入单元至少包括：固定旋转传动件310、转接组件320以及输入电机330。其中，固定旋转传动件310设置在机壳100内，并与输出单元200的齿条210啮合匹配；输入电机330设置在机壳100外部，并通过转接组件320与固定旋转传动件310耦接，用于为固定旋转传动件310提供驱动力。
在本实施例中，可以使用转接方式实现输入电机330与固定旋转传动件310的耦接，例如采用转接组件实现输入电机330与固定旋转传动件310的耦接。如图2和图4所示，本实施例所公开的转接组件320设置在机壳100内，使得固定旋转传动件310经由转接组件320与输入电机330耦接。该转接组件320包括：第一齿轮321和第二齿轮322。第一齿轮321耦接于输入电机330的输出轴，第二齿轮322与固定旋转传动件310耦接，并与第一齿轮321啮合匹配。在输入电机330提供驱动力的情况下，第一齿轮 321转动以驱动与其啮合的第二齿轮322转动，第二齿轮322驱动固定旋转传动件310转动，固定旋转传动件310进一步驱动齿条210作线性运动。也即，本实施例采用齿轮传动实现从输入电机330到固定旋转传动件310的运动传输。此外，转接方式例如也可以是蜗轮蜗杆、带轮或面齿轮等其他形式。
另外，在其他实施例中，也可以使输入电机330直接驱动固定旋转传动件310转动，例如，将固定旋转传动件310耦接于输入电机330的输出轴上。
如图5所示，机壳100包括：至少一个卡槽120以及至少一对滑轨110。其中，卡槽120的侧壁具有安装孔121，输入电机330至少部分设置在安装孔121中，固定旋转传动件310、转接组件320设置于卡槽120内，以限定输入单元的运动范围；滑轨110设置在卡槽120上端，并使得相应的输出单元200设置在其上，以保持输出单元200的线性运动范围。
具体地，如图4所示，固定旋转传动件310、第一齿轮321和第二齿轮322均设置在卡槽120内，使得该固定旋转传动件310仅能够在其中转动，并限制了固定旋转传动件310的其他自由度。滑轨110使得输出单元200仅能够沿着滑轨110运动，并限制了输出单元200的其他自由度。由此，所公开的传动装置提高了传动精度。
如图1-图5所示，固定旋转传动件310的尺寸远小于输出单元200的尺寸，并且滑轨110的尺寸远小于输出单元200的尺寸。
在本实施例中，例如，当所需的传动长度为60mm时，输出单元200的长度至少60mm，机壳的长度仅需20-40mm。或者，当所需的传动长度为大于60mm时，输出单元200的长度至少与传动长度相同，机壳的长度仍为20-40mm。
由此可知，所公开的用于天线的传动装置的机壳、输入单元空间占用较少；并且能够根据所需传动长度配合不同尺寸的输出单元，也即所公开的用于天线的传动装置具有更加灵活的使用范围。
如图2和图4所示，固定旋转传动件310是具有第一齿形的螺旋传动件，分别通过切割第一齿形的螺旋线起始位置和螺旋线终止位置形成相应 的两个第一止挡面311。输出单元200的齿条210具有与第一齿形相匹配的形状，并且在齿条210的两端分别通过填埋齿隙形成相应的两个第二止挡面211。
在本公开内容中，螺旋传动件310可以是蜗杆、螺杆以及丝杆中的任一种。在本实施例中，螺旋传动件310是蜗杆。具体地，在蜗杆驱动齿条210线性运动到齿条210的某一侧时，蜗杆的第一止挡面311与齿条210的相应第二止挡面211配合，使得蜗杆和齿条210均停止运动。
参见图1-图5，所公开的用于天线的传动装置具体工作原理如下：
启动输入电机330，使得输入电机330输出的转动经由转接组件320传输到固定旋转传动件310，然后该固定旋转传动件310的转动运动驱动齿条210做线性运动。具体地，启动输入电机330，使得输入电机330驱动第一齿轮321转动，由于第一齿轮312与第二齿轮322啮合，使得第一齿轮312驱动第二齿轮322转动，基于第二齿轮322与固定旋转传动件310的耦接，使得第二齿轮322带动固定旋转传动件310转动，固定旋转传动件310驱动齿条210作线性运动。
在固定旋转传动件310驱动齿条210线性运动到该齿条210的一侧时，固定旋转传动件310的第一止挡面311与齿条210的相应第二止挡面211配合，使得固定旋转传动件310和齿条210均停止运动。
本申请所公开的用于天线的传动装置使用螺旋传动件310(例如，蜗杆、丝杆或螺杆中的一种)配合齿条210实现转动到平动的传动方式，并且利用止挡面配合(例如，螺旋传动件310的第一止挡面311与齿条210的第二止挡面211配合)的止转方式实现对传动运动的范围限定，同时在机壳100上设置滑轨110限定齿条210的传动方向。一方面，本申请公开的用于天线的传动装置比现有的传动装置具有更少的零件数量和零件种类，降低了制造成本；并且减少了机壳100的体积，从而为天线的布局提供了更大的空间。另一方面，本申请所公开的传动装置的结构能够实现利用较短的旋转部件(例如，固定旋转传动件310)配合较长的平动部件(例如，齿条210)的传动运动模式，并且实现对传动运动的精准控制。
以上所述仅为本公开的实施例可选实施例，并不用于限制本公开的实 施例，对于本领域的技术人员来说，本公开的实施例可以有各种更改和变化。凡在本公开的实施例的精神和原则之内，所作的任何修改、等效替换、改进等，均应包含在本公开的实施例的保护范围之内。
虽然已经参考若干具体实施例描述了本公开的实施例，但是应该理解，本公开的实施例并不限于所公开的具体实施例。本公开的实施例旨在涵盖在所附权利要求的精神和范围内所包括的各种修改和等同布置。所附权利要求的范围符合最宽泛的解释，从而包含所有这样的修改及等同结构和功能。
