Description

一种带有磁聚焦线圈的汽车无线充电装置
技术领域
本发明涉及汽车无线充电领域，尤其涉及一种带有磁聚焦线圈的汽车无线充电装置。
背景技术
汽车无线充电是利用电磁感应现象，由发射线圈产生交变磁场，接收线圈感应出电能进而传输给车载电池。然而由于漏磁、距离等因素的影响，汽车无线充电的传输效率一直是个亟待解决的难题。目前现有的技术提出一种可升降的无线充电系统，使得发射线圈更加靠近车底的接受线圈进而减少漏磁。这种方法可以提高传输效率，但增加了机械传动，从而大大降低了系统的稳定性、安全性、可维护性，缩短了设备寿命，增加了设备成本。
发明内容
针对上述问题，本发明的目的是提供一种带有磁聚焦线圈的汽车无线充电装置，旨在提高汽车无线充电系统的传输效率。
为实现上述目的，本发明提出一种带有磁聚焦线圈的汽车无线充电装置，所述带有磁聚焦线圈的汽车无线充电装置包括第一整流器1、DC/DC变换器2、逆变器3、异形磁铁4、螺旋式发射线圈5、接收线圈6、第二整流器7、车载电池8；其中，
所述第一整流器，将电网的三相交流电整流成直流电，所述DC/DC变换器对直流电的电压进行变换，所述逆变器将直流电逆变成交流电，通过所述螺旋式发射线圈、接收线圈，传至所述第二整流器；
所述第二整流器，将交流电整流成直流电传递至所述的车载电池。
优选地，所述带有磁聚焦线圈的汽车无线充电装置中，所述异形磁铁指的是上下截面积不对等且以磁聚焦为目标的任一形状的磁铁。
优选地，所述带有磁聚焦线圈的汽车无线充电装置中，所述的螺旋式发射线圈呈螺旋状绕于所述的异形磁铁上。
本发明由于采取以上技术方案，其具有以下优点：
1、发射线圈呈螺旋状绕于异形磁铁上，增强了发射线圈所产生的交变磁场的强度，提高了传输效率。
2、避免了机械式升降给汽车无线充电系统带来的维修困难、寿命短、稳定性差等不利影响，并且降低了设备成本。
3、上下不对等的异形磁铁较圆柱形磁铁而言，在相等磁场强度的条件下，可以节省线圈和地下空间，降低设备成本。
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的介绍，显而易见地，下面描述中的附图仅仅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，还可以根据附图示出的结构获得其他的附图。
图1为本发明所提出的带有磁聚焦线圈的汽车无线充电装置结构示意图。
图1中，1、第一整流器，2、DC/DC变换器，3、逆变器，4、异形磁铁，5、螺旋式发射线圈，6、接收线圈，7、第二整流器，8、车载电池。
具体实施方式
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、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部实施例。基于本发明的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
另外，在本发明中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。
本发明提出的一种带有磁聚焦线圈的汽车无线充电装置，用于提高给电动汽车充电的效率。
参照图1，本发明包括第一整流器1、DC/DC变换器2、逆变器3、异形磁铁4、螺旋式发射线圈5、接收线圈6、第二整流器7、车载电池8。
所述第一整流器1，将电网的三相交流电整流成直流电，所述DC/DC变换器2对直流电的电压进行变换，所述逆变器3将直流电逆变成交流电，通过所述螺旋式发射线圈5、接收线圈6，传至所述第二整流器7；
所述第二整流器7，将交流电整流成直流电传递至所述的车载电池8。
进一步地，所述的带有磁聚焦线圈的汽车无线充电装置中，所述异形磁铁4指的是上下截面积不对等且以磁聚焦为目标的任一形状的磁铁。
进一步地，所述的带有磁聚焦线圈的汽车无线充电装置中，所述的螺旋式发射线圈5呈螺旋状绕于所述的异形磁铁上。
当螺旋式发射线圈5通交流电后，产生交变磁场。铁处于磁化物质，其磁化率非常大，铁在磁场中，里面的每个小磁子都受磁场影响，朝一定方向排列，即被磁化为磁铁。小磁子有磁性，于是磁场加强。
本实施例中，所述的异形磁铁4为上下面积不对等，侧面为平滑曲面的圆台。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
