Description
技术领域
本申请涉及一种用于车辆的天线罩,其能够将关于天线罩表面的温度信息反馈给加热电源。
背景技术
具有能够感知周围环境的传感器的车辆是减少道路死亡人数的关键因素。通过传感器可以实现驾驶员辅助功能,从而将风险降到最低,并减少碰撞的可能性。
车辆的设计应该具有美感。因此,必须将传感器集成在车辆内的盖子后,该盖子可以保证传感器实现其功能,将其隐藏在人的视野之外来与车辆的美学设计保持一致。
在雷达传感器中,这种盖子被称为天线罩。如上所述,天线罩必须将其对雷达发射和接收波的影响降至最低。这在恶劣的天气条件下尤为重要,由于可见度变差,道路地面状况等原因,驾驶车辆变得更加危险。显然,水,冰和雪对雷达的功能构成明显的威胁,因为它们会阻挡雷达波并可能沉积在天线罩的表面。
因此,天线罩必须能够去除这些沉积层,比如将它们融化掉。考虑到设计的复杂性,所使用的不同材料以及忠实复制品牌标志所需的装饰技术,将加热器集成到装饰性天线罩中是一项艰巨的任务。
在汽车天线罩中集成加热器的最普遍方法是在天线罩主体中插入金属电线。电流从加热电源流过电线,加热电线及其周围的材料,直到水、冰或雪融化并从天线罩表面去除。
汽车制造商通常会指定在特定的时间跨度内,天线罩表面必须达到的特定温度。另外,汽车制造商对通过加热器流通的可用电压和电流进行了限制和规定。
考虑到电流流通时电线所达到的高温,由于温度变化和接触材料(例如金属导体,树脂、油墨和其他涂层)的不同特性引起的膨胀和收缩,容易造成周围材料的损坏。因此,天线罩的美学外观和射频性能可能由于加热器的存在而遭受损失。
因此,对天线罩的加热进行有效地管理以延长其使用寿命至关重要。加热器被夹在具有不同材料特性的天线罩层之间,因此仅通过监测从加热电源向加热器提供的电压和电流量来获取天线罩表面的温度并不容易。
因此,本申请的一个目的是提供一种能够优化热能管理的天线罩。
发明内容
根据本申请提供的用于车辆的天线罩,可以解决上述缺点,其他优点将在以下进行描述。
根据本申请提供的用于车辆的天线罩包括:前表面,后表面和加热元件,所述加热元件由电源供电,其中天线罩还包括:与所述电源通信的温度传感器。
可选地,所述温度传感器集成在所述天线罩的前表面和后表面之间。
更进一步可选地,所述温度传感器检测所述天线罩的前表面的温度。
所述加热元件也被集成在天线罩的前表面和后表面之间,并且所述温度传感器与所述电源通信,以提供检测到的温度信息并调节由所述电源向所述加热元件提供的功率。
带有控制器的加热电源使用所述检测到的温度信息,以调节提供给所述天线罩中加热元件的加热功率。
这样可以最佳地实现的加热功能,避免不必要的功率浪费,并降低损坏天线罩的风险,从而提高其性能和耐久性。
附图说明
为了更好地理解上述说明并且仅出于提供示例的目的,本申请实施例包括一些非限定性附图,其对本申请的实施例进行了示例性的描述。
图1是根据本申请实施例的用于车辆的天线罩的截面示意图。
具体实施方式
根据本申请的用于车辆的天线罩统一用附图标记1表示,该天线罩1包括或限定:前表面11和后表面12。
应理解,该前表面11是相对于车辆朝向外侧的表面,即暴露于外部环境的表面,而后表面12是相对的表面,如图1所示。
该天线罩1可以具有任何合适的组成,例如,该天线罩可以由在以本申请的申请人的名义的专利文件WO2012066417A1中公开的,具有相同天线罩组成的各层等形成。
根据本申请的该用于车辆的天线罩1还包括:加热元件3,用于加热该天线罩1,并将沉积在该天线罩1的前表面11上的水、冰或雪去除(通过融化)。
该加热元件3,例如,电阻器,由同一车辆或其他车辆的电源4来供电,该电源4例如为电池。该电源向加热元件3提供功率以在合适的温度下加热天线罩1。
如图1所示,可选地,该加热元件3被集成在天线罩1的前表面11和后表面12之间。
该合适的温度由温度传感器5检测,该温度传感器可以是与包括控制器的电源4通信的任何合适的温度传感器,例如温度计。
如图1所示,可选地,该温度传感器5被集成在天线罩1的前表面11和后表面12之间。
可选地,该温度传感器5设置在该前表面11附近,因为检测到的温度更适宜的是前表面11的温度,该前表面11上可能会存在水、冰或雪。
因此,该电源4根据检测到的温度来减少或增加提供给该加热元件3的功率,或者甚至接通或切断加热元件3之间的连接,换句话说,该温度传感器5用作恒温器。
即使已经参考了本申请的具体实施例,对于本领域技术人员来说显而易见的是,本文所述的用于车辆的天线罩易于进行多种变化和修改,在不脱离所附权利要求限定的保护范围的前提下,所提及的所有细节都可以采用其他技术上等效的手段来替代。
