Description

一种羽毛球 技术领域
本发明属于文体用品技术领域，涉及一种羽毛球，具体是一种可以保证羽片偏转角度一致的羽毛球。
背景技术
羽毛球自出现至今已有近200年的历史，羽毛球在结构上分为二段式羽毛球、三段式羽毛球以及球裙一体成型的尼龙羽毛球。二段式羽毛球即是传统的羽毛球，主导产品一般为16片75～77mm的毛片插在一个球头上，然后缠绕二道线圈，再加胶加固。传统羽毛球的球头表面有多个斜向圆孔，这些圆孔圆周排列，成圆台形分布在球头内。羽毛球的羽毛杆横截面是方形，当方形的毛杆插入圆形孔中时，因为圆形的孔对方形毛杆没有导向作用，同时，球头所用材料有一定的收缩率，因而导致毛杆在插入过程中会有一定的变向，这些变向又是不可控且不确定的。这样，即使插毛的夹具调节好夹角，插出来的毛杆间的夹角也会有差异，从而影响羽毛球的飞行稳定性。
三段式羽毛球是在羽毛与球头之间增加了植毛装置，依次由球头、植毛架、多根短毛片组成。其中，植毛架由多个植毛管和植毛杆组成，短毛片的毛杆植入植毛管中。植毛杆部分代替二段式羽毛球羽毛杆的功能，一体成型的植毛架的植毛管之间有二道连接筋代替二段式羽毛球的二道线圈。球裙一体成型的尼龙羽毛球由于球裙成一体，其感觉与传统羽毛球有太大的差别，尽管耐用却只适合在室外使用。
传统羽毛球在制作过程中，最难控制的是稳定性，关键就是毛片间的夹角的一致不好掌控。羽毛是由毛杆与羽翼组成，羽翼因为面积较大，对于熟练工人而言，相邻二羽翼间的夹角的一致性，相对较容易把控，但相邻二根毛杆间的夹角的一致无法判断，更谈不上把控了。
众所周知，羽毛球被击打后，其飞行轨迹是一抛物线。即使从出发点至抛物线最高点飞行是稳定的，仍有30～40％的羽毛球，抛物线最高点下落到地面这一段，羽毛球出现抖动、震动、轻微摇动等现象。其实，这样的羽毛球，严格来讲，其飞行状态也属于不稳定的羽毛球。羽毛球上升过程，动能作用，羽毛球飞行速度较快，此段轨迹的飞行稳定性主要处决于受风面积较大的羽翼，相邻二羽翼间的夹角的一致性越高，此段飞行过程中羽毛球的稳定性越好。而受风面积较小的毛杆，相邻二毛杆间的夹角的一致性对于羽毛球上升过程中的飞行稳定性的影响很小。当羽毛球从抛物线的最高点自由落体，失 去动能的作用，对于飞行稳定性，受风面积较大的羽翼反而失去主导作用，受风面积较小的毛杆起主导作用，相邻二毛杆间的夹角的一致性主导这一飞行轨迹的羽毛球的飞行稳定性。对于传统二段式羽毛球而言，这30～40％的比例，就是最头痛却又无法解决的。
申请号为201710390461.8的中国专利申请中的羽毛球，必须做成一体成型的插腔，而这个一体成型的插接腔不但重量过重，所述插接腔和球头体的连接也过于繁复，导致制作过程难以操控，增加成本。特别是插接腔与球头体很难位于同一中习轴线，那样就会导致羽毛球的稳定性受到影响。
申请号为200980138299.4、名称为“羽毛球运动用羽毛球及羽毛球用底座主体”的中国专利申请公开了一种羽毛球用底座主体，虽然在羽毛球头表面增加了一个对羽毛球羽毛的轴固定用的表面部，但该表面部形成的固定毛杆用的插入孔，而这些插入孔对方形毛杆没有导向作用，同样会导致毛杆在插入过程中会有一定的变向，而这些变向又是不可控且不确定的。这样，即使插毛的夹具调节好夹角，插出来的毛杆间的夹角也会有差异，进而影响羽毛球的飞行稳定性。
发明内容
本发明的目的就是为了克服现有技术的不足，提供一致性好、飞行稳定的羽毛球。
本发明的一种方式：包括羽片和球头，所述的羽片包括羽翼和毛杆，多片羽片圆周围合，毛杆上绕有线圈；所述的球头包括圆柱部分和半球部分，圆柱部分一端与半球部分相接，另一端由端面向内斜向开有多个插毛孔，插毛孔数量与羽片数量n相同，多个插毛孔圆周排列，由球头内部向外呈放射状；多片羽片的毛杆插入对应的插毛孔内，羽片和球头固定连接。
多个插毛孔形状相同，均为方形孔，在垂直于球头中心轴的水平横截面上为方形；多个插毛孔以球头中心轴为中心圆周分布；每个插毛孔转向角α相同，0°≤α≤30°，优选插毛孔转向角α为10°～15°；任意相邻两个插毛孔偏转角β相同，β＝360°/n。
所述的插毛孔转向角α为在所述水平横截面上，插毛孔方形横截面的中心点O和圆柱部分圆形横截面的圆心O′的连线OO′与插毛孔方形横截面的其中一条边线的夹角。
所述的插毛孔偏转角β为在所述水平横截面上，相邻两个插毛孔的方形横截面对应边之间的夹角；一个方形横截面一条边的两个端点到圆心O′的距离，分别与另一个方形横截面一条边的两个端点到圆心O′的距离相同，则该两条边即为一对对应边。
羽片的毛杆的横截面是方形，传统羽毛球球头打的是圆孔，方形毛杆在插入过程中，因为圆形的孔对方形毛杆没有导向作用，同时，球头体的材料有一定的收缩率，因而导 致毛杆在插入过程中会有一定的变向，而这些变向又是不可控且不确定的。这样，即使插毛的夹具调节好夹角，插出来的毛杆间的夹角也会有差异，进而影响羽毛球的飞行稳定性。另外，如果人工调整，即便是熟练工，人工调整每一片毛片间的夹角，也很难使整个羽毛球的毛片间的夹角相对一致，从而影响传统羽毛球的稳定性。本设计中，方形横截面的毛杆插入方形的插毛孔，事先设定转向角的方形孔对于方形毛杆具有定位和导向作用，避免羽片随意转动，保证了羽片的一致性。
设定插毛孔转向角α相同的插毛孔，采用侧身错位叠加的方式使得羽片形成涡流状。每两支相邻羽片之间有一定的间隙，为了保证羽毛球能够稳定飞行，所以间隙必须尽量相同。每一支羽片都会有一个转向角，当相邻二支羽片的转向角一致时，就能保证两支相邻羽片之间的间隙基本相同。传统二段式羽毛球是将毛片直接插接在球头上，球头上的插孔的横截面是圆形的，与横截面为四方形的羽片毛杆不匹配，圆形插孔也不能设置转向角，所以很难控制每支羽片的转向角的角度，使得转向角差异比较大，最终导致羽毛球的飞行稳定性较差。
根据需要，改变α的大小，可以增加或减小羽毛球的旋转，适用各种需求。任意相邻两个插毛孔偏转角β相同，保证每个羽片偏转的角度一致，增加了羽毛球的稳定性。
进一步，所述插毛孔转向角α为插毛孔方形横截面背半球部分一侧以中心点O为回转中心顺时针翻转的角度。
进一步，所述的插毛孔在接近开口处孔径逐渐增加，形成喇叭形的开口，开口与孔壁间通过弧面过渡。该设计可以方便羽片的植入，羽片的毛杆植入插毛孔后，越靠近开口，毛杆与插毛孔的间隙越大，通过加胶固化，可以提高羽片的植入牢固度。
本设计中羽毛球的插毛孔采用方形孔，毛杆在插毛孔中时，方形的插毛孔对毛杆起到定位作用，避免羽片发生偏转，羽毛球稳定性得到提高。同时，插毛孔的转向角α都相同的，也就是羽片的偏转角度相同，羽片侧身错位叠加，间隙基本相同，羽毛球一致性高，该方式使得羽毛形成涡流状，保证羽毛球稳定飞行。
本发明的另一种方式：包括羽片、球头和导向件。所述的羽片包括羽翼和毛杆，多片羽片圆周围合，毛杆上绕有线圈；所述的球头顶部向内斜向开有多个插毛孔，插毛孔数量与羽片数量n相同，多个插毛孔圆周排列，由球头内部向外呈放射状；多片羽片的毛杆插入对应的插毛孔内，羽片和球头固定连接。
所述的导向件包括圆形薄片状的导向片，导向片上开有贯穿薄片的毛杆导向孔；所述的毛杆导向孔为方形孔，数量与羽片数量n相同，以导向片的圆心为中心圆周分布。
所述的毛杆导向孔在导向片的垂直于羽毛球中心轴的水平横截面上为方形；每个毛 杆导向孔转向角

为在所述水平横截面上，毛杆导向孔方形横截面的中心点K和导向片圆形横截面的圆心K′的连线KK′与毛杆导向孔方形横截面的其中一条边线的夹角。
所述的毛杆导向孔偏转角γ为在所述水平横截面上，相邻两个毛杆导向孔的方形横截面对应边之间的夹角；一个方形横截面一条边的两个端点到圆心K′的距离，分别与另一个方形横截面一条边的两个端点到圆心K′的距离相同，则该两条边即为一对对应边。
所述的导向件设置在球头顶部，导向件的毛杆导向孔与球头的插毛孔开口位置一一对应；羽片的毛杆穿过毛杆导向孔后插入插毛孔内。
本设计中，当方形横截面的毛杆穿过毛杆导向孔时，导向片的事先设定转向角的方形孔对于方形毛杆具有定位和导向作用，避免羽片随意转动，保证了羽片的一致性。

相同的毛杆导向孔，采用侧身错位叠加的方式使得羽毛形成涡流状。每两支相邻羽毛的毛片之间有一定的间隙，为了保证羽毛球能够稳定飞行，所以间隙必须尽量相同。每一支羽毛都会有一个转向角，当相邻二支羽毛片的转向角一致时，就能保证两支相邻羽毛片之间有的间隙基本相同。传统二段式羽毛球是将方形横截面的毛杆直接插接在球头上，而球头上的插孔横截面是圆形的，与方形横截面的羽片毛杆匹配，球头上的圆形插孔没有转向角，所以很难控制每支羽毛的转向角的角度，使得转向角差异比较大，最终导致羽毛球的飞行稳定性较差。

为毛杆导向孔方形横截面背向球头一侧以中心点K为回转中心顺时针翻转的角度。
进一步，所述的导向片中心开有通孔，通孔为圆形通孔、方形通孔或多边形通孔。
进一步，所述的导向片上设置有凸起块，n个凸起块以导向片的圆心为中心圆周分布，每个毛杆导向孔开设在对应的凸起块处，并贯穿凸起块及导向片开设。为了减轻羽毛球重量，采用较薄的导向片，而凸起块设计可以延长毛杆导向孔的长度，对于毛杆的插入具有相对好的导向效果。
进一步，所述的导向片上设置有环形凸起，环形凸起以导向片的圆心为中心设置， 凸起块和环形凸起分别设置在导向片的两面，环形凸起为圆环形凸起、四边环形凸起或多边环形凸起。球头顶部平面开有环形凹槽，环形凹槽的形状与环形凸起基本相同，为圆环形凹槽、四边环形凹槽或多边环形凹槽。环形凸起插入环形凹槽，通过粘合剂粘合，这样导向件与球头固定连接。采用四边环形凸起或多边环形凸起，以及四边环形凹槽或多边环形凹槽，可以防止安装时导向片相对球头转动，实现相对准确的定位。
进一步，球头顶部设有与导向件的通孔形状和尺寸对应的柱形凸起，柱形凸起为圆柱体、方柱体或横截面为多边形的柱体，其截面形状和尺寸与对应的导向件通孔基本相同。安装时圆柱形凸起伸入通孔内，该设计也可以将导向件与球头固定连接。柱形凸采用方柱体或横截面为多边形的柱体，相应的通孔采用方形通孔或多边形通孔，可以防止安装时导向片相对球头转动，实现相对准确的定位。
进一步，插毛孔的横截面为圆形或椭圆形。
进一步，所述的插毛孔的横截面为圆形或椭圆形。所述插毛孔的水平横截面为方形，其开口的形状、尺寸和转向角与毛杆导向孔开口的形状、尺寸和转向角基本相同。毛杆在插毛孔中时，方形的插毛孔对毛杆起到导向作用，避免羽片发生偏转，羽毛球稳定性进一步得到提高。因此，插毛孔优选方形孔。
进一步，所述的插毛孔的横截面为圆形或椭圆形。所述的毛杆导向孔远离的球头一端，在接近开口处孔径逐渐增加，形成喇叭形的开口，开口与孔壁间通过弧面过渡。该设计可以方便羽片的植入，羽片的毛杆植入插毛孔后，越靠近毛杆导向孔开口，毛杆与毛杆导向孔的间隙越大，通过加胶固化，可以提高羽片的植入牢固度。
综上，该设计在传统羽毛球的基础上增加了导向件，方形的毛杆导向孔对于横截面方形的毛杆具有定位和导向作用，避免羽片随意转动，保证了羽片的一致性。毛杆导向孔转向角

为在导向件本体的水平横截面中，毛杆导向孔方形横截面的中心点H和导向件本体圆形横截面的圆心H′的连线HH′与毛杆导向孔方形横截面的 其中一条边线的夹角。
所述的毛杆导向孔偏转角γ为在导向件本体的水平横截面中，相邻两个毛杆导向孔的方形横截面对应边之间的夹角；一个方形横截面一条边的两个端点到圆心H′的距离，分别与另一个方形横截面一条边的两个端点到圆心H′的距离相同，则该两条边即为一对对应边。
导向件本体安装在球头顶部，毛杆导向孔与球头的插毛孔开口位置一一对应；羽片的毛杆穿过毛杆导向孔后插入插毛孔。羽片的毛杆的横截面是方形，传统羽毛球球头打的是圆孔，方形毛杆在插入过程中，因为圆形的孔对方形毛杆没有导向作用，导致毛杆在插入过程中会有一定的变向，而这些变向又是不可控且不确定的。这样，即使插毛的夹具调节好夹角，插出来的毛杆间的夹角也会有差异，进而影响羽毛球的飞行稳定性。本设计中，当方形横截面的毛杆穿过毛杆导向孔时，事先设定转向角的方形孔对于方形毛杆具有定位和导向作用，避免羽片随意转动，保证了羽片的一致性。

的大小，可以增加或减小羽毛球的旋转，适用各种需求。任意相邻两个毛杆导向孔偏转角γ相同，保证每个羽片偏转的角度一致，增加了羽毛球的稳定性。
进一步，所述的导向件本体中心开有通孔，此时导向片为环形薄片。这样可以减轻羽毛球整体重量，使之符合羽毛球所需的重量要求。通孔可以是圆形通孔、方形通孔或多边形通孔。
进一步，所述的导向件本体的上端面设置有数量与毛杆导向孔数量相同的凸起块，多个凸起块以导向件本体上端面的圆心为中心圆周分布，每个毛杆导向孔开设在对应的凸起块处，并贯穿凸起块及导向件本体开设。该设计可以在不是增加很多导向件重量的情况下，增加了毛杆导向孔的长度，定位和导向效果更好。
进一步，所述的导向件本体的下端面上设置有环形插接凸起，环形插接凸起以导向件本体下端面的圆心为中心设置，环形插接凸起可以是圆环形凸起、四边环形凸起或多 边环形凸起。相应的，球头顶部平面开有对应形状和尺寸的环形凹槽。环形插接凸起插入环形凹槽，通过粘合剂粘合，这样导向件便与球头固定连接。环形插接凸起采用四边环形或多边环形，可以防止安装时导向件相对球头转动，实现相对准确的定位。
进一步，所述的导向件本体的上端面上设置有环形圈，环形圈以导向件本体上端面的圆心为中心设置，环形圈为圆环形、四边环形或多边环形。对应的，球头顶部设有与环形圈以及通孔形状和尺寸对应的柱形凸起。安装时柱形凸起伸入通孔以及环形圈内，该设计也可以将导向件与球头固定连接。环形圈采用四边环形或多边环形，可以防止安装时导向件相对球头转动，实现相对准确的定位。
再进一步，所述的毛杆导向孔在接近开口处孔径逐渐增加，形成喇叭形的开口，开口与孔壁间通过弧面过渡。该设计更加方便毛杆的插入，越靠近开口，毛杆与毛杆导向孔的间隙越大，通过加胶固化提高植入的牢固度。
再进一步，所述的毛杆导向孔相对于导向件本体的中心轴斜向开设，多个毛杆导向孔形成圆台形结构。该设计保证毛杆按照羽片需要的外扩角插入。
综上，本设计的导向件中毛杆导向孔采用方形孔，毛杆在插入插毛孔过程中，方形孔对毛杆起到定位作用，避免羽片发生偏转，羽毛球稳定性得到提高。同时，毛杆导向孔转向角
Figure PCTCN2019077277-appb-000015
都相同的，保证羽片的偏转角度相同，羽片侧身错位叠加，间隙基本相同，羽毛球一致性高。
导向件本体的上端面设置凸起块，每个毛杆导向孔开设在对应的凸起块处，并贯穿凸起块及导向件本体。因为导向件本体是一簿片，贯穿凸起块及导向件本体的导向孔增加了导向孔的深度，对毛杆的插入过程有更好的导向作用，该导向件保证了羽毛球的一致性，也提高了羽毛球的生产效率。

具体实施方式
一种保证羽片偏转角度一致的羽毛球,可以采用以下两种实施方案。
A实施方案：
如图1和2所示，包括羽片A-1和球头A-2。
羽片A-1包括羽翼A-1-1和毛杆A-1-2，多片羽片A-1圆周围合，毛杆A-1-2上绕有线圈A-1-3。
球头A-2包括圆柱部分A-2-1和半球部分A-2-2，圆柱部分A-2-1一端与A-半球部分A-2-2相接，另一端由端面向内斜向开有多个插毛孔A-2-3，插毛孔A-2-3数量与羽片A-1数量n相同，圆周排列，由球头内部向外呈放射状；多片羽片的毛杆A-1-2插入对应的插毛孔A-2-3内，羽片A-1和球头A-2固定连接。
如图3和4所示，插毛孔A-2-3形状相同，均为方形孔，在垂直于球头A-2中心轴的水平横截面上为方形；多个插毛孔A-2-3以球头A-2中心轴为中心圆周分布。
每个插毛孔A-2-3的插毛孔转向角α相同，0°≤α≤30°，优选插毛孔转向角α为10°～15°时，羽毛球自转效果和飞行轨迹更好。插毛孔转向角α就是在该水平横截面上，插毛孔A-2-3方形横截面的中心点O和圆柱部分A-2-1圆形横截面的圆心O′的连线OO′与插毛孔A-2-3方形横截面的其中一条边线的夹角。因为插毛孔A-2-3为方形孔，在方形横截面的四条边与连线OO′的四个夹角中，两个就是转向角α，另外两个夹角为90°-α。转向角α是指插毛孔A-2-3方形横截面背半球部分A-2-2一侧以中心点O为回转中心顺时针翻转的角度。
任意相邻两个插毛孔A-2-3的插毛孔偏转角β相同，β＝360°/n。本实施例中，羽片数量采用16片，β＝22.5°。偏转角β就是在该水平横截面上，相邻两个插毛孔A-2-3的方形横截面对应边之间的夹角；一个方形横截面一条边的两个端点到圆心O′的距离，分别与另一个方形横截面一条边的两个端点到圆心O′的距离相同，则该两条边即为一对对应边。图4中，AA′边与BB′边、BB′边与CC′边即为两对对应边。
插毛孔A-2-3在接近开口处孔径逐渐增加，形成喇叭形的开口，开口与孔壁间通过弧面过渡。
B实施方案：
如图5所示，包括羽片B-1、球头B-2和导向件B-3。其中，羽片B-1包括羽翼B-1-1和毛杆B-1-2，多片羽片B-1圆周围合，形成圆台形结构，毛杆B-1-2上绕有线圈B-1-3。
球头B-2顶部向内斜向开有多个插毛孔B-2-1，插毛孔B-2-1数量与羽片1数量n相同，圆周排列，由球头内部向外呈放射状(见图9和10)。多片羽片的毛杆B-1-2插入对应的插毛孔B-2-1内，羽片B-1和球头B-2固定连接。插毛孔B-2-1的圆形或椭圆形孔，也可以为方形孔。
如图6所示，导向件B-3包括圆形薄片状的导向片B-3-1，导向片B-3-1上开有贯穿薄片的毛杆导向孔B-3-2。为减轻重量，导向片B-3-1中心可以开有通孔B-3-3，此时导向件B-3为圆环形薄片。

如图9和10所示，导向件B-3设置在球头B-2顶部，导向件的毛杆导向孔B-3-2与球头B-2的插毛孔B-2-1开口位置一一对应。插毛孔B-2-1为方形孔时，其水平横截面 为方形，方形孔开口的形状、尺寸和转向角与毛杆导向孔B-3-2开口的形状、尺寸和转向角基本相同。羽片的毛杆B-1-2穿过毛杆导向孔B-3-2后插入插毛孔B-2-1。
