壳体框架及其制作方法
技术领域

背景技术
现有技术的电子装置通常是具有单色调涂装的壳体框架,并且将柔软感涂装工艺应用于壳体框架,例如,黑色、白色、无色等。这种壳体框架是通过根据视角来改变折射率而显示某种质地。在制作时,分别沉积两种材料。第一种沉积材料具有某特定折射率并且通过从SiO2,TiO2、Al2O3等材料中选择的至少由两种类型的混合物形成;第二种沉积材料具有和第一种沉积材料不同的折射率,也是通过从SiO2,TiO2、Al2O3等材料中选择的至少由两种类型的混合物形成。也可以通过多次交替地沉积两种材料来实现沉积。这种涂装的壳体框架除了可根据使用者的视角通过使亮度和色彩各向异性再现来提供一种陶瓷珍珠质地之外,并没有太多视觉上甚至是触觉上的冲击。
发明内容

其中,微粒包括铜、铝金属颗粒混合物、TiO2/Fe2O3与云母粉磨混合物、铜、铝金属颗粒外包一层聚合物中的至少之一,其中聚合物可以是聚乙烯,聚丙烯和聚苯乙烯中的任一种;其中,微粒和油墨层涂料有显著的折射率差异;其中,壳体框架包括多个油墨层,不同的油墨层添加不同的微粒,具有不同的颜色。
其中,最外层的固化层的剖面为锯齿状,或呈圆弧形。
为解决上述技术问题,本发明采用的另一个技术方案是:提供一种壳体框架的制作方法,包括:将至少一油墨层涂覆在基板上,油墨层掺有包含有色染料的微粒;在每个油墨层上涂覆一固化层,最外层的固化层具有凹凸形状,以在不同的观看角度下呈现不同的色彩和图案;其中,当按压壳体框架时,微粒中的有色染料被释放出来,以根据按压的不同呈现出不同的图案;其中,微粒和油墨层涂料有显著的折射率差异;其中,壳体框架包括多个油墨层,不同的油墨层添加不同的微粒,具有不同的颜色。
其中,微粒包括铜、铝金属颗粒混合物、TiO2/Fe2O3与云母粉磨混合物、铜、铝金属颗粒外包一层聚合物中的至少之一,其中聚合物可以是聚乙烯,聚丙烯和聚苯乙烯中的任一种。
其中,最外层的固化层的剖面为锯齿状,或呈圆弧形。
本发明的有益效果是:区别于现有技术的情况,本发明的壳体框架包括基板,至少一油墨层,涂覆在基板上,油墨层掺有包含有色染料的微粒;至少一固化层,分别涂覆在每个油墨层上,最外层的固化层具有凹凸形状,以在不同的观看角度下呈现不同的色彩和图案;其中,当按压壳体框架时,微粒中的有色染料被释放出来,以根据按压的不同呈现出不同的图案,能够使得壳体框架随着不同的角度变换图案,具有视觉冲击和触觉效果。
附图说明
图1是本发明第一实施例的壳体框架的结构示意图;
图2是图1中的壳体框架的光路示意图;
图3是本发明第二实施例的壳体框架的结构示意图;
图4是本发明第三实施例的壳体框架的结构示意图;
图5是本发明实施例的壳体框架的制作方法的流程示意图。
具体实施方式
请参阅图1,图1是本发明第一实施例的壳体框架的结构示意图。如图1所示,壳体框架10包括:基板11、至少一油墨层12以及至少一固化层14。至少一油墨层12涂覆在基板11上,油墨层12掺有包含有色染料的微粒13;至少一固化层14分别涂覆在每个油墨层12上,最外层的固化层14具有凹凸形状,以在不同的观看角度下呈现不同的色彩和图案。其中,当按压壳体框架10时,微粒13中的有色染料被释放出来,以根据按压的不同呈现出不同的图案。
在本发明实施例中,微粒13包括铜、铝金属颗粒混合物、TiO2/Fe2O3与云母粉磨混合物、铜、铝金属颗粒外包一层聚合物中的至少之一,其中聚合物可以是聚乙烯,聚丙烯和聚苯乙烯中的任一种。微粒13和油墨层涂料有显著的折射率差异。
在本发明实施例中,固化层14的主要成分可以是丙烯酸酯树脂,聚氨酯树脂等,固化层14可以是通过UV光照固化,也可以是双组分材料混合之后通过化学交联固化。最外层的固化层14涂覆之后可以通过相应的模具制作处表面的凹凸立体形状,使得使用者在不同的观看角度下可以呈现不同的色彩和图案,另外不同的按压情况也能呈现出不同的图案。具体地,最外层的固化层14通过模具形成具有锯齿状的表面,即最外层的固化层14的剖面为锯齿状,使得使用者在不同的观看角度下可以呈现不同的色彩和图案。如图3所示,最外层的固化层24还可以呈圆弧形,使得壳体框架20的外观随着观察角度的变化可以呈现更加丰富的变化。
壳体框架10的光路如图2所示,由于不同颗粒和油墨的折射率有差异,其对入射光的反射方向是不同的,锯齿形的表面则只会让集中在某一方向的光线射出,如上图的光路图所示。在不同的观察角度会看到颗粒对入射光在不同方向产生的散射。特定的图案只能在某些特定角度看到,而另外一些角度则不可见,被隐藏起来。如此使得壳体框架随着不同的角度变换图案,具有视觉冲击和触觉效果。
在本发明实施例中,壳体框架可以包括多个油墨层,不同的油墨层添加不同的微粒,具有不同的颜色。每个油墨层上涂覆一固化层,即任两层油墨层之间由固化层隔开。油墨层和固化层的层数视具体情况而定,在此不作限制。如图4所示,壳体框架30包括油墨层33、油墨层36,油墨层33、油墨层36上分别涂覆一固化层34、固化层35。而最外层的固化层34的剖面可以为锯齿状,参见图4。或者也可以呈圆弧形,参见图3。由于多层油墨层的存在,壳体框架在观察时,可以呈现出类似珍珠质地的视觉效果。如果采用多层涂料,光线会发生多次反射,包括镜面反射和漫反射,它们会相互干涉,从而产生类似珍珠质的光泽。
图5是本发明实施例的壳体框架的制作方法的流程示意图。如图5所示,壳体框架的制作方法包括:
步骤S10:将至少一油墨层涂覆在基板上,油墨层掺有包含有色染料的微粒。
其中,微粒包括铜、铝金属颗粒混合物、TiO2/Fe2O3与云母粉磨混合物、铜、铝金属颗粒外包一层聚合物中的至少之一,其中聚合物可以是聚乙烯,聚丙烯和聚苯乙烯中的任一种。微粒和油墨层涂料有显著的折射率差异。
步骤S11:在每个油墨层上涂覆一固化层,最外层的固化层具有凹凸形状,以在不同的观看角度下呈现不同的色彩和图案。
其中,当按压壳体框架时,微粒中的有色染料被释放出来,以根据按压的不同呈现出不同的图案。
在本发明实施例中,固化层的主要成分可以是丙烯酸酯树脂,聚氨酯树脂等,固化层可以是通过UV光照固化,也可以是双组分材料混合之后通过化学交联固化。最外层的固化层涂覆之后可以通过相应的模具制作处表面的凹凸立体形状,使得使用者在不同的观看角度下可以呈现不同的色彩和图案,另外不同的按压情况也能呈现出不同的图案。具体地,最外层的固化层通过模具形成具有锯齿状的表面,即固化层的剖面为锯齿状,使得使用者在不同的观看角度下可以呈现不同的色彩和图案。由于不同颗粒和油墨的折射率有差异,其对入射光的反射方向是不同的,锯齿形的表面则只会让集中在某一方向的光线射出。在不同的观察角度会看到颗粒对入射光在不同方向产生的散射。特定的图案只能在某些特定角度看到,而另外一些角度则不可见,被隐藏起来。如此使得壳体框架随着不同的角度变换图案,具有视觉冲击和触觉效果。
最外层的固化层还可以呈圆弧形,使得壳体框架的外观随着观察角度的变化可以呈现更加丰富的变化,参见图3。
在本发明实施例中,可以将多个油墨层涂覆在基板上,不同的油墨层添加不同的微粒,具有不同的颜色。每个油墨层上涂覆一固化层,即任两层油墨层之间由固化层隔开。油墨层和固化层的层数视具体情况而定,在此不作限制。其中,最外层的固化层的剖面为锯齿状,或呈圆弧形。由于多层油墨层的存在,壳体框架在观察时,可以呈现出类似珍珠质地的视觉效果。如果采用多层涂料,光线会发生多次反射,包括镜面反射和漫反射,它们会相互干涉,从而产生类似珍珠质的光泽。
综上所述,本发明的壳体框架包括基板,至少一油墨层,涂覆在基板上,油墨层掺有包含有色染料的微粒;至少一固化层,分别涂覆在每个油墨层上,最外层的固化层具有凹凸形状,以在不同的观看角度下呈现不同的色彩和图案;其中,当按压壳体框架时,微粒中的有色染料被释放出来,以根据按压的不同呈现出不同的图案,能够使得壳体框架随着不同的角度变换图案,具有视觉冲击和触觉效果。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
