Description
本发明涉及汽车配件技术领域，尤其涉及一种雨刮臂喷嘴、雨刮器及汽车。
市场越来越多汽车配备了雨刮臂喷嘴，由于雨刮臂喷嘴在车运行过程中不会受到风压影响，而且不会耗费多余的水，基本全部喷到刮刷区域，更好的达到清洗与湿润的效果，而且清洁效果更好，因此在视觉和使用上给驾驶者更好体验。
但是由于现在市场上的雨刮臂喷嘴对外形尺寸要求特别小巧，而且还需要包裹球的空间，所以球也只能做很小，喷射形态为点式形状，射在玻璃上呈水柱状，水柱状的水流的覆盖的面积小，空白区域多，雨刮容易干刮从而损坏玻璃。这种点射式雨刮臂喷嘴比较厚，不但洗涤液的利用率降低，更容易遮挡驾驶者的视线。

为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明中的附图，对本发明中的技术方案进行清楚、完整地描述，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他实施例，都属于本发明保护的范围。
结合图8和图9，现有技术中的雨刮臂喷嘴采用点射结构，从雨刮臂喷嘴喷射出去的水呈现柱状形式，在水柱之间具有较大的间隙会雨刮臂在摆动过程中
出现干刷的情况，会使得玻璃受损。
如图1所示，本申请实施例提供了一种雨刮臂喷嘴100，包括喷嘴主体110、安装部120和导流片130。该雨刮臂喷嘴100由三个部件组成，工艺简单，零件少，可以减少制造的成本和人工的成本。
结合图1至4，喷嘴主体110上设置有进水口111，安装部120设置于喷嘴主体110，其内部中空形成安装腔，安装腔底部与进水口111连通。安装部120两端开设有第一开口121以及第二开口122；导流片130插接于安装腔且部分处于第一开口121与第二开口122处。导流片130上设置有第一流道131和第二流道132，第一流道131在第一开口121处形成第一出水口，第二流道132在第二开口122处形成第二出水口；其中，第一流道131与第二流道132连接有自激励流道140，第一流道131在靠近第一出水口的方向逐渐变宽，第二流道132在靠近第二出水口的方向逐渐变宽。
雨刮臂喷嘴100需要对玻璃进行喷射水流时，具有一定压力的水从进水口111进入到安装腔内部，在导流片130的作用下，经过第一流道131和第二流道132分别从第一出水口和第二出水口喷射出去。由于第一开口121与第二开口122处于安装部120的两端，相应地，从第一出水口与第二出水口喷射出去的水流的方向相反；由于第一流道131在靠近第一出水口的方向连接有自激励流道140，第二流道132在靠近第二出水口的方向连接有自激励流道140，那么从第一出水口和第二出水口喷射出去的水则会向着两端呈左右摇摆的扇形扩散，使水的颗粒在扇形区域形成S型均匀分布。因此，水流射在玻璃上的面积大，空白区域少，进而能够避免雨刮干刮损坏玻璃。
结合图12和图13，在一实施例中，自激励流道140包括设置在导流片130上的分流部141，分流部141内部设置有两彼此相对的分流块1411，两分流块
1411与分流部141的内壁之间形成第一导流部1413，两分流块1411之间形成第二导流部1412，其中，第二导流部1412沿靠近第一出水口的方向逐渐变宽。两第一导流部1413处于第二导流部1412的两侧，从两第一导流部1413流动的水与从第二导流部1412流动的水汇合进入到第一出水口或第二出水口，在第一出水口或第二出水口的内壁作用下呈现交叉摇摆状态。
在某些具体的实施例中，从第一出水口和第二出水口喷射出的扇形的水流夹角可以达到140°-180°。这样，使得水流的覆盖面积变大。
当导流片130插接于安装腔，导流片130处于第一流道131和第二流道132两侧的部分与安装部120的内壁贴合以形成第一出水通道和第二出水通道。需要理解的是，第一流道131和第二流道132为在导流片130表面的槽体结构。当导流片130紧贴安装部120的内壁，那么水流则会经第一出水通道和第二出水通道的导向进行流动，使得水能够在第一出水口和第二出水口均匀喷射，其中，第一流道131与第二流道132的流向相反。这样，从两个方向进行喷射，覆盖面积更大。
如图4所示，在其中一个实施例中，第一流道131与第二流道132处于导流片130的同一侧。第一流道131和第二流道132共同使用同一个进水通道，水流从入到进水通道，然后在第一流道131和第二流道132的交汇处分散开来并分别进入到第一流道131和第二流道132，然后从第一出水口和第二出水口喷射出去。
如图5和图6所示，在另一个实施例中，第一流道131与第二流道132处于导流片130的两侧。第一流道131和第二流道132分别采用两个独立的进水端，水流从两个进水端分别进入到第一流道131和第二流道132，然后从第一出水口和第二出水口喷射出去。相比于第一流道131与第二流道132设置在导流
片130的同一侧，此处的导流片130合理的利用了导流片130的空间，使得导流片130的结构更小。
本申请中，第一流道131或第二流道132均包括两彼此相对的流道壁133，其中，两流道壁133自第一出水口或第二出水口向安装腔内部逐渐靠拢。两个流道壁133彼此之间呈相交状。在某些具体形状下，第一流道131和第二流道132在第一开口121处和第二开口122处均呈梯形状态。需要注意的是，安装导流片130与安装部120安装密封后在自激励流道140的作用下，可以使得从第一出水口和第二出水口喷射出去的水流呈扁平的扇形状，且水流呈左右摇摆状，水的颗粒在扇形区域内形成S型均匀分布，使得喷射的水流更加均匀。
结合图1至图3，在一实施例中，安装部120上设置有限位块123，限位块123处于第二开口122的下方。当导流片130插接安装腔，限位块123与导流片130抵靠。为了避免导流片130在插接安装腔时容易因为水流压力的作用导致松动影响喷射效果，导流片130与安装部120之间是过盈配合。安装部120与限位块123共同对导流片130限位以使得导流片130的安装稳定。
进一步地，第一开口121大于第二开口122，第一开口121形成安装部120的插入端。导流片130从第一开口121插入到安装部120内，在抵靠到限位块123时停止运动，此时，导流片130与限位块123以及安装部120的两侧内壁以及顶部内壁抵接。这样，将导流片130从第一开口121插入，使得雨刮臂喷嘴100的安装更加方便。
更进一步地，限位块123内凹形成卡接部124，卡接部124呈凹槽状，导流片130上设置有延伸段134，延伸段134能够插入卡接部124。延伸段134与凹槽的槽口处之间过盈配合，即，当延伸段134插入到凹槽内，延伸段134与凹槽的内壁贴合，这样，当导流片130在安装部120内压入到位时，可以防止水
流从凹槽与导流片130之间的缝隙中流出，避免影响喷嘴的喷射效果。
如图1所示，在一实施例中，安装部120为喷嘴主体110的一部分，安装部120与喷嘴主体110均为塑料件，由塑料件注塑一体而成，方便对喷嘴主体110的制造。同时，安装部120与喷嘴主体110的连接处平滑，避免在导流片130插入时与导流片130之间有较大间隙，使得导流片130插入时有良好的密封性，保证了喷射效率。
本申请的雨刮臂喷嘴100由喷嘴主体110、导流片130以及安装部120组成，零件少，结构简单，便于安装；安装部120与喷嘴主体110一体连接且导流片130与安装部120过盈配合，使得喷嘴结构紧凑，可以减少制造的成本和人工成本。
结合图7、图10和图11所示，本发明第二方面提供一种雨刮器200，包括雨刮臂210以及上述任一实施例的雨刮臂喷嘴100，雨刮臂喷嘴100设置在雨刮臂210上，第一出水口和第二出水口分别朝向雨刮臂210相反的两个方向。由于从第一出水口和第二出水口喷射出去的水呈摇摆的扇形状态，且该雨刮器200的雨刮臂喷嘴100从两个方向进行喷射，覆盖面积大且喷射均匀，便于雨刮臂210刮扫。由于雨刮臂喷嘴100的喷射覆盖面积大，喷射均匀，雨刮臂210在转动时不会将水甩远，进而避免阻挡驾驶员的视线。
本发明第三方面提供一种汽车，包括两个如上实施例的雨刮器200。两个雨刮器200转动设置在汽车上，用于对汽车的玻璃进行喷水刮扫。
由于汽车具有上述实施例的雨刮器200，因此，汽车具有雨刮器200能够实现的上述的有益效果，在此不再赘述。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员
应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
