Description

一种轨道车辆及其车顶天线安装座
本申请要求于2015年03月12日提交中国专利局、申请号为201510108418.9、发明名称为“一种轨道车辆及其车顶天线安装座”，以及要求于2015年03月12日提交中国专利局、申请号为201520141425.4、发明名称为“一种轨道车辆及其车顶天线安装座”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及轨道车辆技术领域，特别是轨道车辆的天线安装座。本发明还涉及设有所述天线安装座的轨道车辆。
背景技术
铁路系统都拥有独特的无线通信与调度系统，通常涵盖从中短波波段直到微波波段的数个段频。
天线是列车与调度中心联系的渠道，铁路机车或动车的头车上一般至少需要安装三副以上的天线来进行无线通信，除此之外，还普遍安装了GPS卫星定位系统。
由于车顶空间有限，因此在车顶合理的布置和安装天线便显得尤为重要。
现有的轨道车辆车顶天线虽然都通过天线安装座固定在车顶，但由于天线安装座设计不合理，安装后会削弱车顶天线安装处的车体强度，而且，当车辆高速行驶时，气密性较差，对整车气动性能影响较大。
因此，如何保证车顶天线安装处的车体强度，满足车体气密要求，以及减小车顶天线对整车气动性能的影响，是本领域技术人员需要解决的技术问题。
发明内容
本发明的第一目的是提供一种车顶天线安装座。该安装座可保证车顶天线安装处的车体强度，满足车体气密要求，并显著减小车顶天线对整车气动性能的影响。
本发明的第二目的是提供一种设有所述车顶天线安装座的轨道车辆。
为实现上述目的，本发明提供一种车顶天线安装座，包括：
底座，呈中空箱型结构；
顶板，位于所述底座顶部，其周边相对于所述底座向外延伸形成卡接边沿，内顶部固定有天线安装用螺接座，顶面设有一圈周向封闭的凸起，所述凸起围合的内部区域为车顶天线安装区；
线缆通孔，纵向贯通所述底座和顶板。
优选地，所述线缆通孔位于所述顶板中央，并在车体前后方向上偏向于后侧。
优选地，所述线缆通孔由固定于所述底座内部的圆形套筒形成。
优选地，所述底座的底板相对于侧壁在纵向方向上向内缩进一定距离。
优选地，所述螺接座为在车体宽度方向上横向焊接于所述顶板内顶部的扁平状矩形空心型材，其上的螺纹孔与所述顶板上的螺纹孔相对应，且在车体宽度方向上左右对称分布。
优选地，所述底座的内腔中填充有隔热材料。
优选地，所述隔热材料为发泡剂。
优选地，所述底座在横截面上呈正方形，所述顶板呈尺寸大于所述底座横截面的长方形，所述车顶天线安装区呈矩形。
为实现上述第二目的，本发明还提供一种轨道车辆，包括车体和车顶天线，所述车顶天线通过安装座安装于所述车体顶部，所述安装座为上述任一项所述的车顶天线安装座；所述车顶天线的底部通过螺钉或螺栓固定于所述车顶天线安装区，其周边与所述凸起形成的环形区域内填充密封胶；所述底座嵌入所述车体顶部的安装孔内，所述顶板的卡接边沿支撑于所述车体顶部。
优选地，所述车顶天线安装座与所述车体顶部满焊连接。
本发明的安装座为中空箱体结构，箱体内焊接有天线安装用螺接座，保证了天线安装强度的同时，降低了安装座整体重量，满足了动车组轻量化设计的理念，且安装座以沉降的方式安装于动车组车顶，减小了车顶天线安装高度，提高了车体外形平顺化，满足了动车组流线型设计的要求， 此外，安装座安装面设置有周圈凸起，天线安装后可以通过涂打密封胶的方式进一步提高整车气密性能。可以满足动车组对气密性及流线型设计的需求，亦适用于地铁、城际车等各种车顶配置天线的轨道车辆，特别是空调装置安装在车辆顶部的轨道车辆。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。

图2为图1的A-A视图；
图3为图1的B-B旋转视图；
图4为图1所示车顶天线通过图1所示安装座安装在车体顶部的结构示意图。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参考图1、图2、图3，图1为本发明所提供车顶天线安装座的一种具体实施方式的俯视图；图2为图1的A-A视图；图3为图1的B-B视图。
在一种具体实施例中，本发明提供的车顶天线安装座主要由底座1和顶板2两大部分组成。
其中，底座1呈中空箱型结构，在横截面上呈正方形，其底板1-1相对 于侧壁1-2在纵向方向上向内缩进一定距离，呈向内凹进的形状，顶板2位于底座1顶部，呈尺寸大于底座1横截面的长方形，其周边相对于底座1向外延伸形成卡接边沿。
顶板2内顶部固定有天线安装用螺接座3，此螺接座3为在车体宽度方向上横向焊接于顶板2内顶部的扁平状矩形空心型材，各螺接座3上的两个螺纹孔与顶板2上的螺纹孔相对应，且在车体宽度方向上左右对称分布，用于通过螺钉或螺栓对天线进行固定，为螺钉或螺栓提供对应的连接位置。
如图所示，顶板2的顶部还设有一圈周向封闭的凸起4，其可以与顶板2为一体式结构，也可以分别单独加工然后组装在一起，凸起4围合的内部区域为车顶天线安装区，在俯视图上，此车顶天线安装区呈矩形，顶板2上的螺纹孔位于车顶天线安装区内部。
由于车顶天线5在安装后，其线缆6需要从车顶引入至车体内部，以建立电力和通信连接，因此，该车顶天线安装座上还设有线缆通孔7，在结构上，线缆通孔7纵向贯通底座1和顶板2。
具体地，线缆通孔7由固定于底座内部的圆形套筒形成，其位于在车体前后方向上偏向于后侧的中央位置。
为进一步提高天线安装部位的隔热性能，可以在底座的内腔中填充隔热材料(图中未示出)，例如发泡剂等；而且，为提高底座的结构强度，还可以在底座内部设计相应的加强筋等结构，以便在满足减重要求的前提下，提高天线安装部位的车体强度。
上述底座1和顶板2虽然设计呈矩形，但具体并不局限与此，根据车顶安装空间的布局和需要，还可以设计呈圆形、半圆形、椭圆形、三角形、梯形、多边形等其他形状。
此外，螺接座3的形式也不局限于条状型材，还可以是焊接在顶板2内顶部的螺母，或者开设有螺纹孔的连接块，等等，甚至可以省去螺接座，安装时，用螺母从内部将螺栓锁紧。
对于常规线缆，尤其是集束型线缆，图中所示线缆通孔基本上就可以满足天线的走线要求。但考虑到在某些特殊情况下，天线的线缆可能比较分散，对此，可设计多个线缆通孔7，分别用于穿过不同位置、不同类型的 天线，线缆通孔7的形成也不必完全依靠套筒，出于简化的考虑，可以省去套筒，将线缆直接从上至下依次穿过顶板上的通孔、底座内部、底座底板上的通孔引入车体内部，但由于套筒能够对从其内部穿过的线缆起到很好的保护作用，因此是较为理想的方案。
总之，上述内容仅是本发明车顶天线安装座的优选方案，具体并不局限于此，在此基础上可根据实际需要作出具有针对性的调整，从而得到不同的实施方式。由于可能实现的方式较多，这里就不再一一举例说明。
请参考图4，图4为图1所示车顶天线通过图1所示安装座安装在车体顶部的结构示意图。
除了上述车顶天线安装座，本发明还提供一种轨道车辆，包括车体8和车顶天线5，车顶天线5通过安装座安装于车体8顶部，其中，安装座为上文中所述的车顶天线安装座。
如图所示，车顶天线安装座的底座1嵌入车体8顶部的安装孔内，顶板2的卡接边沿支撑于车体顶部，车顶天线5的底部通过螺钉9(或螺栓)固定于车顶天线安装区，并与车体顶部满焊连接，其周边与凸起4之间形成一圈环形区域，环形区域的内部填充密封胶10，车顶天线5的底部厚度大于凸起4，因此，密封胶10的顶部呈斜面，车顶天线5的线缆6穿过线缆通孔7从车顶引入至车体内部，以建立电力和通信连接。
由于安装座为中空箱体结构，箱体内焊接有天线安装用螺接座3，保证了天线安装强度的同时，降低了安装座整体重量，满足了动车组轻量化设计的理念，且安装座以沉降的方式安装于动车组车顶，减小了车顶天线5的安装高度，提高了车体外形平顺化，满足了动车组流线型设计的要求。
此外，安装座安装面设置有周圈凸起4，车顶天线5安装后能通过涂打密封胶10的方式进一步提高整车气密性能。可以满足动车组对气密性及流线型设计的需求，亦适用于地铁、城际车等各种车顶配置天线的轨道车辆，特别是空调装置安装在车辆顶部的轨道车辆。
以上对本发明所提供的轨道车辆及其车顶天线安装座进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的核心思想。应当指出，对于本技 术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
