Description

车辆用灯具以及车辆用灯具的制造方法
技术领域
本发明涉及车辆用灯具以及车辆用灯具的制造方法。详细地说，涉及关于透光罩的熔敷面将在熔敷头的移动方向邻接区域的朝向的角度变化量设为所定值以下、通过透光罩和灯罩熔敷确保良好的结合状态的技术领域。
背景技术
车辆用灯具至少设有一方开口的灯罩以及闭塞灯罩开口、与灯罩结合的透光罩，光源配置在由透光罩和灯罩构成的灯具外壳的内部空间。
在这种车辆用灯具中，作为结合透光罩和灯罩的方法，有熔敷方法(例如，参照专利文献1)。通过熔敷使得透光罩和灯罩的结合是在设在透光罩的熔敷部的熔敷面推压在形成在灯罩的被熔敷面的状态下，通过从激光熔敷装置的熔敷头对着熔敷部照射激光实行。
激光从熔敷部的熔敷面的相反侧的面(外表面)入射到熔敷部，照射透光罩的熔敷面和灯罩的被熔敷面相接的部分，熔敷面和被熔敷面熔融，透光罩和灯罩结合。这时，熔敷头沿着形成环状的熔敷部移动，从沿着熔敷部移动的熔敷头射出的激光追随熔敷面的朝向，熔敷头的角度随时变化，使得激光相对熔敷面垂直入射。
这样，通过移动时熔敷头的角度变化，激光相对熔敷面垂直入射，激光熔敷面的能量分布不会产生大的偏差，在熔敷部整体，能确保透光罩和灯罩间的良好的结合状态。
[专利文献1]日本特开2008-4487号公报
但是，透光罩根据车辆形状等形成各种各样的形状，熔敷部的熔敷面的朝向也因位置而形成不同，因此，如上所述，为了使得激光相对熔敷面垂直入射，追随熔敷面的朝向，熔敷头的角度变化。
但是，激光熔敷装置的性能有一定的限度，因此，因熔敷面朝向变化程度，存在熔敷头不能追随熔敷面的朝向变化的可能性。
若熔敷头不能追随熔敷面的朝向变化，则在不实行追随的部分，激光不能相对熔敷面垂直照射，能量分布发生大的变化，存在透光罩和灯罩之间产生结合不良的危险。
发明内容
本发明就是为解决上述问题而提出来的，本发明的课题在于，确保透光罩和灯罩的通过熔敷的良好的结合状态。
为了解决上述课题，本发明的车辆用灯具在设在透光罩的熔敷部的熔敷面被推压在形成在灯罩的被熔敷面的状态下，从熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合，上述熔敷头沿着上述熔敷面移动，且在移动时根据上述熔敷面的朝向使得角度变化；在上述熔敷头的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，车辆用灯具在熔敷部整体，熔敷头角度变化，使得激光相对熔敷面以一定的角度范围入射。
又，本发明的车辆用灯具在设在透光罩的熔敷部的熔敷面被推压在形成在灯罩的被熔敷面的状态下，从熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合，上述熔敷面相对上述熔敷头100移动，且在移动时根据上述熔敷面的朝向使得角度变化；在上述熔敷面的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，车辆用灯具在熔敷部整体，熔敷面相对熔敷头角度变化，使得激光相对熔敷面以一定的角度范围入射。
又，本发明的车辆用灯具的制造方法包括以下步骤：
将设在透光罩的熔敷部的熔敷面推压在形成在灯罩的被熔敷面上；以及
在该状态下，一边使得熔敷头沿着上述熔敷面移动，且在移动时根据上述熔敷面的朝向使得角度变化，一边从上述熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合；
其中，在上述熔敷头的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，在制造车辆用灯具中，在熔敷部整体，熔敷头角度变化，使得激光相对熔敷面以一定的角度范围入射。
又，本发明的车辆用灯具的制造方法包括以下步骤：
将设在透光罩的熔敷部的熔敷面推压在形成在灯罩的被熔敷面上；以及
在该状态下，一边使得上述熔敷面相对熔敷头移动，且在移动时根据上述熔敷面的朝向使得角度变化，一边从上述熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合；
其中，在上述熔敷面的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，在制造车辆用灯具中，在熔敷部整体，熔敷面相对熔敷头角度变化，使得激光相对熔敷面以一定的角度范围入射。
下面说明本发明的效果。
按照本发明技术方案(1)的发明，车辆用灯具在设在透光罩的熔敷部的熔敷面被推压在形成在灯罩的被熔敷面的状态下，从熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合，上述熔敷头沿着上述熔敷面移动，且在移动时根据上述熔敷面的朝向使得角度变化；在上述熔敷头的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，熔敷头相对熔敷面的追随性高，根据熔敷面的朝向，熔敷头的角度变化，使得激光相对熔敷面的入射角度总是成为一定，能确保透光罩和灯罩通过熔敷的良好的结合形态。
按照本发明技术方案(2)的发明，车辆用灯具在设在透光罩的熔敷部的熔敷面被推压在形成在灯罩的被熔敷面的状态下，从熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合，上述熔敷面相对上述熔敷头100移动，且在移动时根据上述熔敷面的朝向使得角度变化；在上述熔敷面的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，熔敷面相对熔敷头的追随性高，根据熔敷面的朝向，熔敷面移动角度变化，使得激光相对熔敷面的入射角度总是成为一定，能确保透光罩和灯罩通过熔敷的良好的结合形态。
按照本发明技术方案(3)的发明，在上述熔敷头或熔敷面的移动方向邻接的区域的上述熔敷面的与上述移动方向正交的朝向的角度变化量设为0.5°/mm以下。
因此，在熔敷头或熔敷面的移动方向邻接的区域的熔敷面的与上述移动方向正交的朝向变化场合，能根据熔敷面的朝向使得熔敷头的角度变化，使得激光相对熔敷面的入射角度总是成为一定，能确保透光罩和灯罩通过熔敷的更良好的结合形态。
按照本发明技术方案(4)的发明，上述熔敷面的至少一部分相对作为上述熔敷部的上述熔敷面的相反侧的面的外表面倾斜。
因此，能不受透光罩形状或外表面朝向的约束，自由地设定熔敷面的朝向，能容易地使得熔敷面的朝向的角度变化量形成为0.5°/mm以下。
按照本发明技术方案(5)的发明，上述透光罩通过注射模塑成形由树脂材料形成；将上述透光罩的外周部设为不与上述灯罩进行熔敷的非熔敷部；在上述非熔敷部的内周侧，与上述非熔敷部连续设置上述熔敷部；当将上述熔敷部的上述非熔敷部侧一端的厚度设为X，上述熔敷部的另一端的厚度设为Y，上述非熔敷部的最大厚度设为Z时，使得上述厚度X比上述厚度Y小，上述厚度X比上述最大厚度Z小。
因此，熔敷面整体厚度不厚，且熔敷面的最小厚度比非熔敷部的最大厚度薄，能尽可能使得熔敷面的厚度薄，能抑制注射模塑成形时发生气孔。
按照本发明技术方案(6)的发明，车辆用灯具的制造方法包括以下步骤：
将设在透光罩的熔敷部的熔敷面推压在形成在灯罩的被熔敷面上；以及
在该状态下，一边使得熔敷头沿着上述熔敷面移动，且在移动时根据上述熔敷面的朝向使得角度变化，一边从上述熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合；
其中，在上述熔敷头的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，熔敷头相对熔敷面的追随性高，根据熔敷面的朝向，熔敷头的角度变化，使得激光相对熔敷面的入射角度总是成为一定，能确保透光罩和灯罩通过熔敷的良好的结合形态。
按照本发明技术方案(7)的发明，车辆用灯具的制造方法包括以下步骤：
将设在透光罩的熔敷部的熔敷面推压在形成在灯罩的被熔敷面上；以及
在该状态下，一边使得上述熔敷面相对熔敷头移动，且在移动时根据上述熔敷面的朝向使得角度变化，一边从上述熔敷头相对上述熔敷部照射激光，上述透光罩和上述灯罩通过熔敷结合；
其中，在上述熔敷面的移动方向邻接的区域的上述熔敷面的朝向的角度变化量设为0.5°/mm以下。
因此，熔敷面相对熔敷头的追随性高，根据熔敷面的朝向，熔敷面移动角度变化，使得激光相对熔敷面的入射角度总是成为一定，能确保透光罩和灯罩通过熔敷的良好的结合形态。

具体实施方式
下面，参照附图说明用于实施本发明车辆用灯具的最佳形态。在以下实施形态中，虽然对构成要素，种类，组合，形状，相对设置等作了各种限定，但是，这些仅仅是例举，本发明并不局限于此。
车辆用灯具1如图1所示，包括具有朝前方开口的凹部的灯罩2，以及闭塞灯罩2的开口面、由透明的树脂材料形成的透光罩3，由灯罩2和透光罩3构成灯具外壳4。
没有图示的光源配置在灯具外壳4的内部。在车辆用灯具1中，若从光源射出光，则射出的光透过透光罩3向外部照射。
灯罩2的外周部的前端面形成作为被熔敷面2a。
透光罩3由例如无色透明的第一部分5以及带有红色等所定色、有色透明的第二部分6构成。第二部分6设在从外周侧围住第一部分5的位置。
透光罩3的外周部设为非熔敷部7(参照图2)。透光罩3的与非熔敷部7的内侧连续的部分设为熔敷部8，熔敷部8的与灯罩2的被熔敷面2a对向的面形成作为熔敷面9。
透光罩3根据车辆或灯罩2的形状等形成各种各样形状，具有“熔敷部8的熔敷面9的朝向也因位置而不同”的部分。
图3及图4表示透光罩3的熔敷面9的各一部分。
熔敷面9例如图3所示，具有沿长度方向(周向)延伸的平缓的曲面状的曲面部9a，又，例如图4所示，具有沿长度方向延伸的平缓的曲面状且在宽度方向平缓地弯曲的曲面部9b。熔敷面9的曲面部9a、9b不管其位置，朝向不同。
又，熔敷面9还具有平面部9c。熔敷面9的平面部9c根据其位置设为朝向相同。
熔敷面9的至少一部分相对作为熔敷部8的熔敷面9的相反侧的面的外表面10倾斜(参照图2)。
熔敷面9的长度方向(周向)与激光熔敷装置的熔敷头100移动的移动方向一致。因此，熔敷头100沿着熔敷面9移动。
在透光罩3的熔敷面9被推压在灯罩2的被熔敷面2a上，灯罩2和透光罩3保持在没有图示的保持部件的状态下，熔敷头100相对灯罩2和透光罩3移动。也可以设为在透光罩3的熔敷面9被推压在灯罩2的被熔敷面2a的状态下，灯罩2和透光罩3相对熔敷头100移动。
从熔敷头100相对熔敷面9射出用于进行熔敷的激光R，熔敷头100设为在移动时能根据熔敷面的朝向使得角度变化。
熔敷面9如上所述，一部分设为曲面部9a、9b，曲面部9a、9b形成为使得倾斜角度满足以下那样的条件(参照图5)。
在熔敷面9中，在作为距离L、L各为1mm的等间隔的位置A、位置B、位置C引切线，分别将该切线设为切线As、切线Bs、切线Cs，将切线As和切线Bs形成的角度设为α，切线Bs和切线Cs形成的角度设为β。距离L、L为熔敷头100的移动方向的距离。
这时，角度α和角度β哪个都设为0.5°以下。在图5中，为了容易理解，夸张表示各距离及各角度。
在本发明中上述所谓“0.5°以下”包含0.5°。
这样，车辆用灯具1在熔敷头100的移动方向邻接区域的熔敷面9的朝向的角度变化量在熔敷面9整体，设为0.5°/mm以下。因此，在熔敷头100的移动方向，在熔敷面9整体，角度变化量小，因此，熔敷头100的相对熔敷面9的追随性高，熔敷头100根据熔敷面9的朝向，角度变化，使得射出激光R的相对熔敷面9的入射角度总是成为垂直(90°)。
在上述说明中，例示在熔敷头100的移动方向邻接区域的熔敷面9的朝向的角度变化量设为0.5°/mm以下，但是，也可以再加上在与熔敷头100的移动方向正交方向邻接区域的熔敷面9的朝向的角度变化量设为0.5°/mm以下。
例如，关于形成沿长度方向延伸的平缓的曲面状且在宽度方向平缓地弯曲的曲面部9b(参照图4)，可以将在熔敷头100的移动方向邻接区域的与上述移动方向正交的朝向的角度变化量设为0.5°/mm以下。
这样，通过将在熔敷头100的移动方向邻接区域的熔敷面9的与上述移动方向正交的朝向的角度变化量设为0.5°/mm以下，在熔敷头100的移动方向邻接区域的熔敷面9的与上述移动方向正交的朝向变化场合，能根据熔敷面9的朝向，使得熔敷头100的角度变化，使得激光R的相对熔敷面9的入射角度总是成为垂直(90°)。
下面，说明透光罩3的非熔敷部7和熔敷部8的关系(参照图6)。
如上所述，透光罩3的外周部设为非熔敷部7，与非熔敷部7的内侧连续的部分设为熔敷部8。
将熔敷部8的非熔敷部7侧一端的厚度设为X，熔敷部8的另一端的厚度设为Y，非熔敷部7的最大厚度设为Z，形成透光罩3，使得厚度X比厚度Y小，且厚度X比最大厚度Z小。
通过使得非熔敷部7和熔敷部8具有上述那样的尺寸关系，熔敷面9整体厚度不厚，且熔敷面9的最小厚度比非熔敷部7的最大厚度薄，能尽可能使得熔敷面9的厚度薄，能抑制注射模塑成形时发生气孔。
如上所述，车辆用灯具1在熔敷头100的移动方向邻接区域的熔敷面9的朝向的角度变化量设为0.5°/mm以下。
因此，熔敷头100相对熔敷面9的追随性高，能根据熔敷面9的朝向，使得熔敷头100的角度变化，使得激光R的相对熔敷面9的入射角度总是成为垂直(90°)，能确保透光罩3和灯罩2的通过熔敷的良好的结合状态。
在上述最佳形态中所示的各部的形状及结构都不过是实施本发明时进行的具体化一例，并不因上述实施形态限定解释本发明的技术范围。
