为使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施方式，对本发明进行进一步的详细说明。应当理解的是，此处所描述的具体实施方式仅用以解释本发明，并不限定本发明的保护范围。
如图1，图4所示，为本发明展示的一种具有多层屏蔽结构的电调控制装置，包括：驱动模块100，所述驱动模块100包括驱动模块屏蔽壳120和驱动模块端盖140，所述驱动模块屏蔽壳120设有相互连通的第一开口122、装配容腔124和第二开口126，所述驱动模块端盖140罩设于所述第二开口126处，所述装配容腔124的内壁凸设有驱动件屏蔽壳200，所述驱动件屏蔽壳200将所述装配容腔124隔分形成至少第一屏蔽腔室腔124a；及控制模块300，所述控制模块300包括相互联接的控制模块端盖320和控制模块屏蔽壳340，所述控制模块屏蔽壳340由所述第一开口122伸入并嵌套于所述第一屏蔽腔室腔124a内，所述控制模块端盖320罩设于所述第一开口122处。
上述具有多层屏蔽结构的电调控制装置中通过将驱动模块屏蔽壳120设计 为具有相互连通的第一开口122、装配容腔124和第二开口126的中空腔体结构，之后将驱动模块端盖140罩设于第二开口126处实现端封，之后在装配容腔124的内壁凸设形成驱动件屏蔽壳200，将装配容腔124隔分形成至少第一屏蔽腔室腔124a，之后将控制模块300的控制模块屏蔽壳340由第一开口122伸入并嵌套于第一屏蔽腔室腔124a内，此时控制模块端盖320罩设于第一开口122处实现端封。如此通过上述驱动模块屏蔽壳120、控制模块屏蔽壳340及驱动件屏蔽壳200可以形成内外叠层布置的三层屏蔽结构，如此能够有效将控制模块300和/或驱动模块100工作时泄露的控制信号完全且可靠屏蔽于三层屏蔽结构内，从而最大限度的减少对天线互调的影响，进而提高天线产品的互调水平。
在上述实施例中，控制模块端盖320与控制模块屏蔽壳340可以是一体式结构，也可以是可装拆的装配式结构；同理，驱动模块屏蔽壳120与驱动模块端盖140同样可以是一体式结构，或者可以是可装拆的装配式结构。
进一步的，所述控制模块屏蔽壳340与所述第一屏蔽腔室腔124a的内壁间隙配合。因而通过控制模块屏蔽壳340与第一屏蔽腔室腔124a的内壁间隙配合，可以确保控制模块300与驱动模块100的插拔装拆操作更加省力，此外，还能避免两个壳体间发生摩擦磨损，进而提高机构的使用寿命。此外，第一屏蔽腔室腔124a的内壁上沿第一开口122至第二开口126的方向还延伸对称设有两个导向凸条，当配合间隙较大时，控制模块屏蔽壳340直接与导向凸条滑动接触，可以对控制模块屏蔽壳340起到良好导向作用，且优选导向凸条采用减磨材料制作，以避免对控制模块屏蔽壳340造成磨损损害。
请参照图2，此外，在上述实施例的基础上，所述控制模块屏蔽壳340设有用于容置所述驱动件屏蔽壳200的避空槽342，当所述控制模块屏蔽壳340伸入所述第一屏蔽腔室腔124a内时，所述驱动件屏蔽壳200滑动嵌套于所述避空槽342内。因而当控制模块屏蔽壳340伸入第一屏蔽腔室腔124a内时，避空槽342可以容置驱动件屏蔽壳200，进而避免发生干涉碰撞导致两者无法正常装配。具体的，控制模块屏蔽壳340的横截面和第一屏蔽腔室腔124a的横截面均为相适配的U型结构。其他实施方式中，驱动件屏蔽壳200还可以设置于靠近第一屏蔽腔室腔124a的内侧壁上，进而使第一屏蔽腔室腔124a形成截面为L型结构， 适配地，控制模块屏蔽壳340的截面也为L型结构。
请参照图1，所述控制模块端盖320的外周面设有相配合的第一连接座322和锁紧件324，所述驱动模块屏蔽壳120靠近所述控制模块300一端的外周面上设有第二连接座128，当所述控制模块屏蔽壳340嵌套入所述第一屏蔽腔室腔124a内后，所述锁紧件324与所述第一连接座322、所述第二连接座128均配合锁固。因而当控制模块屏蔽壳340嵌套入装配容腔124内时，通过锁紧件324与第一连接座322和第二连接座128锁固配合，可以提高控制模块300与驱动模块100的连接牢固性，进而提升装置使用可靠性，且该连接方式装拆方便。
上述第一连接座322、锁紧件324和第二连接座128为一组锁紧机构，本实施例中，锁紧机构的数量为四组，并以两两均分的方式对称设置于控制模块端盖320宽度方向的两侧面上。因而当控制模块屏蔽壳340嵌套入装配容腔124内时，通过锁紧件324与第一连接座322和第二连接座128锁固配合，可以提高控制模块300与驱动模块100的连接牢固性，进而提升装置使用可靠性，且该连接方式装拆方便。其中，锁紧件324可以是螺钉，第一连接座322和第二连接座128上均设有位置相对应的螺孔，当控制模块端盖320与驱动模块屏蔽壳120拼合时，螺钉旋入两个螺孔内实现牢固连接；此外，上述第一连接座322和第二连接座128上开设有通孔，锁紧件324是销钉，通过销钉与通孔插接实现控制模块端盖320与驱动模块屏蔽壳120的连接固定；或者第一连接座322上设有卡钩，第二连接座128上设有卡槽，通过卡钩与卡槽的卡固实现控制模块端盖320与驱动模块屏蔽壳120的连接固定，或者在其他实施方式中控制模块端盖320与驱动模块屏蔽壳120还可以采用其他的装配结构实现连接。
此外，所述控制模块屏蔽壳340设有安装腔室，所述安装腔室内安设有控制电路，所述控制模块屏蔽壳340远离所述控制模块端盖320的外端面上设有与所述控制电路电连接、并用于传输控制信号的连接插头344，所述驱动模块端盖140上设有用于获取控制信号的连接插口142，当所述控制模块屏蔽壳340嵌套入所述第一屏蔽腔室腔124a内时，所述连接插头344与所述连接插口142插接配合。因而当控制模块屏蔽壳340套接入第一屏蔽腔室腔124a内时，连接插头344恰好与连接插口142插接配合，确保实现驱动模块100与控制模块300 的通信连接，且该装配方式连接可靠，信号传输稳定逼真，可以避免出现使用线缆插拔连接的方式存在的信号泄露问题。其中，连接插头344的数量为间隔设置的两个，并均与控制电路的一端电性连接，控制电路的另一端与控制模块端盖320上的信号端口(例如串联端口、接收端口等)电性连接；相应地，连接插口142的数量也为间隔设置的两个，连接插头344与连接插口142一一对应配合插接，如此可以提高连接及信号传输的可靠性。且需要说明的是，控制模块屏蔽壳340与驱动模块屏蔽壳120的长度应当满足两者相互套接时，连接插头344恰好与连接插口142插接，从而消除插接不到位而无法正常工作的问题发生。
如图3所示，所述驱动件屏蔽壳200还将所述装配容腔124隔分有第二屏蔽腔室124b，所述驱动模块端盖140上还设有至少一个驱动电机400，所述驱动电机400嵌套入所述第二屏蔽腔室124b内。因而通过将驱动电机400嵌套入第二屏蔽腔室124b内，可以避免电机工作时线圈产生的磁场对控制信号的传输稳定和逼真产生影响。
进一步的，所述驱动模块端盖140上安设有2个或以上的所述驱动电机400，2个或以上的所述驱动电机400均设置于所述驱动件屏蔽壳200内、并用于分别控制不同频段或/波束天线的下倾角。因而在驱动模块端盖140上同时安设2个以上的驱动电机400并均嵌设于驱动件屏蔽壳200内，不仅可以避免影响控制信号传输稳定，同时可以实现对不同频段/波束天线的下倾角进行调节，大大提升装置的使用性能。需要说明的是，根据所需控制频段/波束的数量与驱动电机400数量一一对应，驱动电机400的数量增加，驱动件屏蔽壳200所围成的容腔大小也可以做出适应性的改进，相应地，驱动模块屏蔽壳120的大小也可以做出适应性的改进，如此可以提高具有多层屏蔽结构的电调控制装置的适用范围。
此外，需要说明的是，所述驱动件屏蔽壳200的长度与所述驱动模块屏蔽壳120的长度相适配，即驱动件屏蔽壳200的两端部与驱动模块屏蔽壳120的两端部平齐，如此不仅可以确保驱动件可以完全包覆于驱动件屏蔽壳200内，提升电机线圈产生的磁场不会对控制信号传输造成影响的可靠性，同时避免驱动件屏蔽壳200过长导致无法与驱动模块端盖140和控制模块300正常装配。
进一步的，所述控制模块屏蔽壳340设有用于安装或取出所述控制电路、并与所述安装腔室连通的第三开口346，所述控制模块端盖320可拆卸罩设于所述第三开口346处。因而通过控制模块端盖320与控制模块屏蔽壳340的第三开口346的可拆卸连接，可以便于进行控制电路的安装、维修和更换。
上述实施例中的插拔方式是首先将控制模块300和驱动模块100插装为一个整体模块，之后再一同装入天线的安装腔室内；出现部件损坏时，可通过控制模块端盖320将两者一同拔出，之后再将控制模块300与驱动模块100分离，将损坏模块更换之后与未损坏模块重新组装并一同使用。另一种插拔方式为首先将驱动模块100可拆卸地安设于所述安装腔室的内壁上，之后再将控制模块300嵌套入驱动模块100的装配容腔124内并插接连接。出现部件损坏时，可先通过控制模块300抽拔出，再将驱动模块100抽拔出的顺序进行维护更换。如此可以提高装置在不同使用条件下的安装与维护需要。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
