Description

一种车载天线盒结构 技术领域
本发明涉及全球定位系统（GPS）车载导航和天线技术，具体涉及一种车载天线盒结构，尤其应用于分离式车载导航系统。
背景技术
现代生活中，随着自驾游方式日渐流行、规模化汽车货物运输日渐成为趋势，越来越多的车辆选择组队出行。车队的头车上往往会配备熟悉路况或者熟悉车辆调度的领航人，头车因此也称作领航车辆。在行驶过程中，由领航车辆领航，其他车辆跟随领航车辆行驶。为了防止车队中的个别车辆掉队，车队中的各台车辆彼此之间不可间隔过长的距离。领航人通过移动通信设备，例如手机、对讲机等，对车队的各个车辆的位置进行询问、指导。由于一个车队首位车辆的距离一般都有数百米至上千米，车队中每个车辆驾驶人员不可能记得本车队所有的车，且现代社会的路况都比较复杂，因此，当车队中的个别车辆因为红绿灯、行驶速度较慢、被其他车辆所阻隔、或者交通事故等各种情况掉队时，领航人很难及时知晓具体情况以至于无法及时进行调度，同时领航人也难以回头去寻找掉队车辆，致使掉队车辆离整个车队越来越远，掉队车辆就要花费很大时间和精力才能回到车队。因此，使用现有技术中的车队领航方法进行车队领航难度非常大。使用现有技术车队领航系统进行车队领航的难度非常大，使用现有技术车队导航装置进行车队导航的难度非常大。
内嵌式车载智能控制系统（含GPS导航）包括芯片、天线、中央处理器、内存、屏幕、按键、扬声器等组成部分，除天线部分外一起合为一个底座，一般都安装在汽车中控台，屏幕朝外。目前，车载智能控制系统使用多项无线技术（移动通讯、手机电视、GPS等），采用多个对应天线，现有的内嵌式车载智能控制系统有安装在屏幕背后的内部天线，还有一个或多个外部天线，这给用户带来以下不便：
1、多个外部天线使用连接不便并占用底座上的接口；
2、内部天线信号不佳，外部天线缺乏保护；
3、功能单一。
本申请人的在先申请提出了分离式车载导航系统，在天线盒内统一管理天线，并且引入中央处理器（CPU）等电路。但由于CPU等电路影响，使天线盒内电路板元器件合理布置、天线摆放和CPU散热都是须要解决的技术问题。
