Description

挡风玻璃雨刮
本发明涉及一种挡风玻璃雨刮，它也可称作挡风罩雨刮。
本发明尤其是涉及一种具有一弯曲的骨架并可具有变化的宽度和/或厚度的挡风玻璃雨刮。本技术领域的技术人员可以理解，骨架可以是一根在一个平面内弯曲或可具有空间曲率的梁的形式。该梁将具有宽度和厚度尺寸。该梁沿其长度的每个点还将具有一曲率半径。
申请人进行了大量的分析和实验，并认为已发现了宽度、梁材料的杨氏模量和梁总长度以及厚度、梁材料的杨氏模量和总长度之间的关系，它可以使挡风玻璃雨刮以改进的方式工作。
在本说明书中，除非文中另外明确指明，术语“空间加固”应理解为表示一横截面的实际周边与包络该横截面的可能的最短周边相一致。
按照本发明的一个方面，提供了一种挡风玻璃雨刮，它包括：
一细长的弯曲骨架，它由杨氏模量在50到350 GPa之间的弹性韧质材料制成，该骨架沿其长度基本上在所有的点具有一基本空间加固的横截面形状，其中沿骨架基本在最宽点处的宽度Wm的大小(用毫米表示)最大为(-8.889×10-5×E+0.05378)×L-5.25，式中，L是骨架的总长度，用毫米表示，E是骨架材料的杨氏模量，用GPa表示。
进一步按照这一方面，提供了一种挡风玻璃雨刮，它包括：
一细长的弯曲骨架，它由杨氏模量在50到350 GPa之间的弹性韧质材料制成，该骨架沿其长度基本上在所有的点具有一基本空间加固的横截面形状，其中沿骨架基本在最宽点处的宽度大小与骨架总长度L的比Rw最大为(-8.889×10-5×E+0.05378)-5.25/L，式中，L为骨架的总长度，用毫米表示，E为骨架材料的杨氏模量，用GPa表示。
按照本发明的第二个方面，提供了一种挡风玻璃雨刮，它包括：
一细长的弯曲骨架，它由杨氏模量在50到350 GPa之间的弹性韧质材料制成，该骨架沿其长度基本上在所有的点具有一基本空间加固的横截面形状，其中沿骨架基本在最厚点处的厚度Tm的大小最大为0.0007×L-0.0027407×E+1.37814，式中，L为骨架的总长度，用毫米表示，E为骨架材料的杨氏模量，用GPa表示。
进一步按照这一方面，提供了一种挡风玻璃雨刮，它包括：
一细长的弯曲骨架，它由杨氏模量在50到350 GPa之间的弹性韧质材料制成，该骨架沿其长度基本上在所有的点具有一基本空间加固的横截面形状，其中沿骨架基本在最厚点处的厚度大小与骨架总长度L的比Rt最大为0.0007-(0.0027407×E-1.37814)/L，式中，L为骨架的总长度，用毫米表示，E为骨架材料的杨氏模量，用GPa表示。
骨架的材料可以是一种复合材料。在这种情况下，杨氏模量将是该复合材料的杨氏模量。
骨架的总长度可以约为300毫米到1200毫米。
骨架沿其长度可以具有变化的宽度和/或厚度。骨架可以具有在一个平面内的自由态曲率，也可以具有空间曲率(也就是在两个平面内弯曲)。
下面参照附图以实例的方式来描述本发明，附图中：
图1是本发明的挡风玻璃雨刮的立体示意图；
图2是图1挡风玻璃雨刮处于未负载的自由态条件下的侧视图；
图3是表示图1和2所示挡风玻璃雨刮的骨架的宽度变化的曲线图；
图4是表示图1和2所示挡风玻璃雨刮的骨架的厚度变化的曲线图；以及
图5是表示图1和2所示挡风玻璃雨刮的骨架的中心线的自由态坐标的曲线图。
在附图中，本发明的挡风玻璃雨刮总的由标号10表示。挡风玻璃雨刮10包括一梁形式的骨架12和一橡胶刮板14。该梁由杨氏模量为200 GPa的弹簧钢制成。梁的长度为600毫米。梁沿其长度在所有点处均具有矩形的横截面形状。因此，梁具有一宽度尺寸W和一厚度尺寸T，如图1中所示。梁的宽度和厚度从其中央朝其自由端或尖端变小，分别如图3和4所示。图3表示沿梁长度的不同位置处的梁宽度(用毫米表示)，梁长度也用毫米测量。图4表示沿梁长度的不同位置处的梁厚度(用毫米表示)，梁长度也用毫米测量。
梁在一个平面内沿纵向弯曲，沿其长度在每一点处具有一预定的曲率半径R，如图2中所示。图5表示相对于沿梁长度(用毫米表示)的位置的梁中心线坐标。
利用给出的公式，可以判定图中所描绘的雨刮是否符合本发明。沿梁12在其最宽点处的梁12的宽度Wm(用毫米表示)为15.4，如图3中所示。按照本发明的第一个方面，在L为600毫米、E为200GPa的情况下，沿梁12在最宽点处的宽度Wm的大小(用毫米表示)应小于(-8.889×10-5×E+0.05378)×L-5.25=(-8.889×10-5×200+0.05378)×600-5.25=16.35毫米。因此，雨刮的宽度Wm落在本发明的范围之内。
沿梁12在最厚点处的梁12的厚度Tm(用毫米表示)为1.2毫米，如图4中所示。按照本发明的第二个方面，在L为600毫米、E为200GPa的情况下，沿梁12在最厚点处的厚度Tm的大小(用毫米表示)应小于0.0007×L-0.0027407×E+1.37814=0.0007×600-0.0027407×200+1.37814=1.25毫米。因此，雨刮的厚度Tm也落在本发明的范围之内。
