Description

汽车用简约式电控单元电器盒 
技术领域
本发明属电子控制电路电路板，尤其涉及汽车用电控单元电路板。 
背景技术
随着现代汽车的发展，汽车的电子化程度逐年增加.电子技术已在车辆发动机控制、底盘控制、故障诊断、ABS以及音响、导航等各个方面得到广泛应用，显著提高了车辆的动力性、经济性、安全性、稳定性和舒适性。目前电控电路板是将控制电路与功率元器件分开，做成上下两层板，中间通过接插件进行连接，上层为控制电路，下层为功率元器件，下层板与壳体之间设与电路大小相同的导热硅胶片进行散热。其缺陷是，两层电路板中间以连接器插件连接，大大增加了电路板的体积；消耗硅胶及连接件的元器件消耗多；连接点多，线路可靠性降低。 
发明内容
为了克服现有技术存在的问题，本发明的目的是提供一种汽车用电控电路板，体积小、制作成本低、散热效果好、易于实施、安全可靠。 
汽车用简约式电控单元电器盒，包括盒体、盒盖和电路板，电路板和盒盖固定在盒体上，特点是，电路板板面设功率元器件区、控制电路区，分别固装功率元器件和控制线路；功率元器件直接由焊接连接在电路板的背面；盒体由金属压铸成型，具有良好的热传导性能，盒体底部对应功率元器件区设置形状、大小相同的凸台；功率元器件区背面与凸台之间设置导热硅胶片，通过盒体传导散热。 
与现有技术相比，优点是：控制线路和功率元器件分区设置，结构简约、合理，散热效果良好；体积小，节省材料，易于加工；电路板减少中间连接，安全可靠。 
附图说明
对照附图对本发明作进一步说明。 
图1是汽车简约式电控单元电器盒结构示意图。 
图2是图1的俯视图 
具体实施方案 
由图1、图2可以看出，汽车用简约式电控单元电器盒，由盒体1、盒盖5、电路板4组成，盒体1沿口设螺钉孔，底部设凸台2。电路板3设功率元器件区6、控制线路区7和螺钉孔，功率元器件区固装的功率元器件，穿过电路板4直接焊接连接在电路板的背面，控制线路区7固装控制线路。电路板功率元器件区7背面与盒体1的凸台2之间垫设导热硅胶片3。用螺钉将电路板4、导热硅胶片3固定在盒体1，用螺钉将盒盖5固定在盒体1上。
