Description
本发明涉及移动通信基站技术领域，尤其涉及一种电调天线下倾角的显示装置及电调天线。
现有电调天线下倾角的显示方式中，常见有以下几种：一、外露部分显示方式：刻度尺逐渐露出外露部分以显示刻度，但是外露部分极易被损坏。二、刻度尺拔出读数方式：刻度尺被弹簧压缩，显示时需要拔出刻度尺读数，一方面内部的弹簧对交调有影响，一方面度数不够直接。三、圆盘显示方式：通过蜗轮蜗杆的转换或较多齿轮的变比转化显示刻度，这种方式由于较多变比机构的参与导致显示精度较差。同时随着天线集成度的提高，天线大部分至少为16端口，因此急需体积小，读数简易的方式显示下倾角度。

图1～图3示出了本发明实施例提供的优选电调天线下倾角的显示装置的结构，所述电调天线下倾角的显示装置100包括外壳10以及设于外壳10内的驱动齿轮轴20、变比齿轮轴30、刻度环驱动轴40和刻度环50。
所述外壳10的内部设有至少一个柱体结构60，外壳10的表面设有透明窗口70。优选的是，外壳10在对应刻度环50的一个转动路径位置设有透明窗口70。所述外壳10用于支撑电调天线下倾角的显示装置100的内部结构的同时，形成透明窗口70用以读取内部刻度环50的读数。如1所示，优选透明窗口70处或附近设有用于指示刻度值的箭头71，剪头71指向的刻度值即为下倾角的当前刻度值。更好的是，外壳10由透明塑胶材料制成，优选采用透明PC(聚碳酸酯)制成。本实施例中，所述外壳10为长方体型，但外壳10的形状并不受具体限制，还可以是任意的多边体型、柱体型或不规则型等。
所述驱动齿轮轴20上分别设有连接件21和第一换向齿轮22，如图2和图3所示，连接件21与天线传动装置内的螺杆连接，作为动力来源。移相器工作时会使得螺杆转动，接着螺杆通过连接件21带动驱动齿轮轴20转动。优选的是，驱动齿轮轴20的一端设有连接件21，另一端设有第一换向齿轮22。更好的是，连接件21为花键，所述花键与螺杆连接。
所述变比齿轮轴30上分别设有第二换向齿轮31和第一变比齿轮32，如图2和图3所示，第二换向齿轮31与驱动齿轮轴20的第一换向齿轮22相互啮合，形成动力源的换向。优选的是，第一换向齿轮22为第一伞状齿轮22，第二换向齿轮31为第二伞状齿轮31，第一伞状齿轮22与第二伞状齿轮31相互啮合，可将横向旋转动力转化为垂直方向的旋转。更好的是，变比齿轮轴30的中部设有第二换向齿轮31，且变比齿轮轴30的一端设有第一变比齿轮32。
所述刻度环驱动轴40上分别设有第二变比齿轮41和多个凸起42，如图2和图3所示，第二变比齿轮41与变比齿轮轴30的第一变比齿轮32相互啮合。优选的是，第一变比齿轮32为第一直齿轮32。第二变比齿轮41为第二直齿轮41，且第一直齿轮32的齿数大于第二直齿轮41的齿数。这样，变比齿轮轴30的一端齿数较少的第一直齿轮32，与刻度环驱动轴40端头的齿数较多的第二直齿轮41啮合，形成联动和变比。优选的是，刻度环驱动轴40的一端设有第二变比齿轮41，刻度环驱动轴40的中部设有凸起42。
优选的是，所述第一直齿轮32的齿数与第二直齿轮41的齿数之比为1：4，使得变比齿轮轴30的第一直齿轮32与刻度环驱动轴40的第二直齿轮41的传动比为4：1，保证天线内移相器的位移量等同刻度环50的每个刻度的间隙，达到数值显示的精准化、清晰化。优选的是，本实施例中刻度环驱动轴40的凸起42为立方体型，但凸起42的形状并不受具体限制，还可以是任意的多边体型、圆柱体型或不规则型等。并且，本实施例中凸起42在刻度环驱动轴40上均匀分布，但实际上凸起42也可以在刻度环驱动轴40上不均匀分布。
所述刻度环50绕接于刻度环驱动轴40和柱体结构60上，如图2和图3所示，并且刻度环50上对应切割设有多个切孔51，所述切孔51与刻度环驱动轴40上的凸起42的形状相匹配，以便刻度环驱动轴40上的凸起42能插入切孔51内，保证刻度环50与刻度环驱动轴40同步转动。这样，驱动齿轮轴20与变比齿轮轴30将横向旋转动力转化为垂直方向的旋转，同时带动刻度环驱动轴40 旋转，继而让刻度环50旋转以显示读数。
优选的是，刻度环50包括塑胶材料制成的带状体，带状体上印有刻度值。优选刻度环50采用乳白色PET(聚对苯二甲酸乙二醇酯)膜并丝印黑色刻度值，侧边切割出切孔51用以被驱动。本实施例中，所述刻度环50的切孔51为长方体形，但切孔51的形状并不受具体限制，还可以是任意的多边体形、圆形或不规则形等。并且，切孔51可以在刻度环50上均匀分布或不均匀分布。
本发明通过驱动齿轮轴20、变比齿轮轴30、刻度环驱动轴40三个齿轮轴的换向、变比和联动，即而驱动刻度环50自转实现刻度值变化，并通过透明窗口70便可直接读取下倾角的当前刻度值。借此，本发明体积小巧、结构简单、读数简易，在提高下倾角的显示精度的同时，避免手动操作繁琐。
优选的是，所述外壳10包括壳体11和盖体12，如图2和图3所示，壳体11设有容置腔和与容置腔连通的开口，盖体12和壳体11可拆卸连接以遮蔽开口。驱动齿轮轴20、变比齿轮轴30、刻度环驱动轴40、刻度环50和柱体结构60容置并固定于壳体11的容置腔中。优选的是，壳体11和盖体12由透明塑胶材料制成，优选采用透明PC(聚碳酸酯)制成。
优选的是，所述壳体11包括底部和包围底部的侧壁，如图2和图3所示，底部和侧壁共同形成容置腔和开口。变比齿轮轴30、刻度环驱动轴40、刻度环50和柱体结构60固定于底部上并容置于容置腔中，而透明窗口70设于所述侧壁上。优选的是，壳体11的侧壁在对应刻度环50的一个转动路径位置设有透明窗口70。如1所示，透明窗口70处或附近设有用于指示刻度值的箭头71。本实施例中，所述壳体11为长方体型，但壳体11的形状并不受具体限制，还可以是正方体型、柱体型或不规则型等。
优选的是，所述壳体11上还开设有动力接入口13，如图3所示，驱动齿轮轴20的第一换向齿轮22通过动力接入口13伸入容置腔内并与变比齿轮轴30的第二换向齿轮31相互啮合，驱动齿轮轴20的连接件21则置于容置腔之外并与螺杆连接。
优选的是，所述壳体11的底部边缘对称设有四个空心的第一柱体61，如图2所示，盖体12的底面边缘对应设有四个第二柱体62，第二主体62的直径小于所述第一柱体61的空心直径，以便四个第二柱体62分别嵌入四个第一柱体61中形成四个柱体结构60，然后将刻度环50绕接于刻度环驱动轴40和四个柱 体结构60上。一方面，壳体11的第一柱体61与盖体12的第二柱体62套接形成柱体结构60的方式，使得电调天线下倾角的显示装置100的整体结构更加稳固；另一方面，刻度环50绕接于一个刻度环驱动轴40和四个柱体结构60的绕法，可以保证刻度环50有足够的长度丝印刻度值，同时保证透明窗口70可设置地足够大，能够显示更多刻度值和便于肉眼识别。
本发明电调天线下倾角的显示装置100的工作原理如下：
一、移相器工作时，对应的螺杆转动，所述螺杆通过连接件21带动驱动齿轮轴20转动。
二、驱动齿轮轴20进行转动，并通过相互啮合的第一换向齿轮22和第二换向齿轮31带动变比齿轮轴30进行换向转动，即通过第一换向齿轮22和第二换向齿轮31的配合将横向旋转动力转化为垂直方向的旋转。
三、变比齿轮轴30进行转动，并通过相互啮合的第一变比齿轮32和第二变比齿轮41带动刻度环驱动轴40进行变比转动。
四、刻度环驱动轴40进行转动，并通过凸起42插入刻度环50的切孔51来带动刻度环50转动。
五、刻度环50通过转动带来刻度值的变化，并通过透明窗口70显示下倾角的刻度值变化。具体而言，可通过壳体11的透明窗口70及箭头71的指示，读取下倾角的当前刻度值，实现功能。
本发明电调天线下倾角的显示装置100的优点包括：
(1)无刻度尺或其他结构件伸出端盖，避免损坏。
(2)无需手动操作，刻度直接在外壳显示，可直接读数。
(3)无复杂变比机构，移相器的行程变化直接对应刻度变化，提高显示精度。
本发明还提供一种电调天线，包括有如图1～3所示的电调天线下倾角的显示装置100。
综上所述，本发明电调天线下倾角的显示装置包括外壳以及设于外壳内的驱动齿轮轴、变比齿轮轴、刻度环驱动轴和刻度环。移相器工作时使螺杆转动，螺杆通过连接件带动驱动齿轮轴转动，驱动齿轮轴通过相互啮合的第一换向齿轮和第二换向齿轮带动变比齿轮轴进行换向转动，变比齿轮轴通过相互啮合的第一变比齿轮和第二变比齿轮带动刻度环驱动轴进行变比转动，刻度环驱动轴 通过凸起和切孔带动刻度环转动，刻度环通过转动在透明窗口中显示刻度值变化。本发明通过三个齿轮轴的换向、变比和联动，即而驱动刻度环自转，并通过透明窗口便可直接读取下倾角的当前刻度值。借此，本发明体积小巧、结构简单、读数简易，并能够提高下倾角的显示精度，避免手动操作繁琐。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
