本公开涉及电子设备技术领域，具体的，涉及壳体组件及其制备方法和电子设备。
背景技术
现有技术，为了在玻璃外观上显示出美观的纹理，常在PET膜片上通过UV转印形成UV胶纹理层。长期使用过程中，PET膜层容易发生老化和变形，使得PET膜层上附着的UV纹理层发生开裂，纹理效果变差。为了避免PET变形带来的纹理开裂，有人提出直接在玻璃内表面直接喷涂UV胶，然后通过带有纹理的模具滚压UV胶，然后经过紫外曝光处理后形成UV胶纹理层，但在玻璃表面通过曝光方式形成UV纹理层容易出现断线或气泡，良率低。
因而，目前的玻璃壳体外观装饰相关技术仍有待改进。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本发明的一个目的在于提出一种直接在玻璃两个相对的表面形成双层立体纹理，并通过双层立体纹理的光学干涉使壳体组件形成特殊的摩尔纹外观的壳体组件。

在本公开的另一方面，本公开提供了一种制备壳体组件的方法。根据本公开的实施例，该方法包括：在玻璃的相对的两个表面上形成具有预定图案的干膜，得到待蚀刻玻璃；将所述待蚀刻玻璃浸入蚀刻液中预定时间，以得到玻璃基体，所述玻璃基体具有相对的第一表面和第二表面，所述第一表面具有蚀刻形成的微米级第一立体纹理，所述第二表面上具有蚀刻形成的微米级第二立体纹理，所述第一立体纹理在垂直方向上的正投影和所述第二立体纹理在所述垂直方向上的正投影不完全重叠，并使得第一立体纹理和第二立体纹理的反射光发生干涉；去除所述玻璃基体上的所述干膜。该方法可以快速、高效的制备获得具有双层立体纹理的壳体组件，步骤简单、操作容易、制作良率高，且得到的壳体组件可以形成特殊的摩尔纹外观，呈现出更炫更立体的外观装饰效果，同时长时间使用不易变形。

发明详细描述
下面详细描述本公开的实施例。下面描述的实施例是示例性的，仅用于解释本公开，而不能理解为对本公开的限制。实施例中未注明具体技术或条件的，按照本领域内的文献所描述的技术或条件或者按照产品说明书进行。所用试剂或仪器未注明生产厂商者，均为可以通过市购获得的常规产品。
在本公开的一个方面，本公开提供了一种壳体组件。根据本公开的实施例，参照图 1，该壳体组件包括：玻璃基体10，所述玻璃基体具有相对的第一表面11和第二表面12，所述第一表面具有微米级第一立体纹理110，所述第二表面上具有微米级第二立体纹理120，所述第一立体纹理110在垂直方向上的正投影和所述第二立体纹理120在所述垂直方向上的正投影不完全重叠，以使得所述第一立体纹理110和所述第二立体纹理120的反射光发生干涉。该壳体组件中，直接在玻璃两个相对的表面形成双层立体纹理，无需喷涂UV胶，提高了制作良率，且在玻璃表面直接形成的立体纹理已经固定，不易变形，很好地解决了装饰可靠性及制作良率的问题，并通过双层纹理的光学干涉可以使得壳体组件形成特殊的摩尔纹外观，呈现出更炫更立体的外观装饰效果，可以极大地提高产品的外观吸引力和竞争力。
具体的，根据干涉原理，干涉是两列或两列以上的波在空间中重叠时发生叠加从而形成新的波形的现象，具体到本公开的壳体中，光照射到壳体上的立体纹理时，由于立体纹理表面凹凸不平，不同位置处的反射光之间的光程会存在差异，这样反射光之间就会发生干涉，这样，第一立体纹理表面不同位置的反射光之间会发生干涉，第二立体纹理表面不同位置的反射光之间也会发生干涉，同时第一立体纹理的反射光和第二立体纹理的反射光之间还会发生干涉，在双层立体纹理的干涉作用下，壳体外表面可以呈现出干涉产生的明暗条纹，即摩尔纹，形成特殊的外观效果。具体的摩尔纹形状和排布方式则可以根据第一立体纹理和第二立体纹理的形状和排布方式进行调整。
需要说明的是，本文中的描述方式“微米级第一立体纹理”和“微米级第二立体纹理”是指第一立体纹理和第二立体纹理的线宽和线距均为微米级，即为1～1000微米范围内。如果线宽和线距过小，一方面不易于加工，另一方面光照到过小尺寸的纹理上，会发生分光现象，无法呈现出微米级纹理条件下的摩尔纹外观，而如果线宽和线距过大，则无法满足干涉的条件，无法产生摩尔纹外观。
在一些实施例中，玻璃基体的具体种类可以为适用于电子设备壳体的任何玻璃，例如可以为硅酸盐玻璃(具体如石英玻璃、高硅氧玻璃、钠钙玻璃、铝硅酸盐玻璃、硼硅酸盐玻璃等)、硼酸盐玻璃、磷酸盐玻璃等等。而所述玻璃基体的厚度可以为0.5～8mm，具体如0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1mm、2mm、3mm、4mm、5mm、6mm、7mm、8mm等。另外，玻璃基体的具体结构也可以根据实际需要选择，例如可以为平板玻璃、2.5D玻璃或者3D玻璃。
一些具体实施例中，参照图2，所述第一立体纹理110和所述第二立体纹理120可以均向所述玻璃基体10内部凹陷。由此，在保证良好的摩尔纹外观的前提下，可以方便的通过蚀刻工艺进行制备，且纹理的棱角向内凹陷，不易损伤和破坏。
根据本公开的实施例，第一立体纹理和第二立体纹理的具体形状、分布位置、尺寸等等可以根据想要实现的外观效果进行调整。一些具体实施例中，所述第一立体纹理110的线宽(即立体纹理的宽度)d1和所述第二立体纹理120的线宽d2各自独立的为1～100微米(具体可以为100微米、80微米、50微米、40微米、30微米、20微米、15微米、10微米、9微米、8微米、7微米、6微米、5微米、4微米、3微米、2微米、1微米等)；一些具体实施例中，所述第一立体纹理110的线距(即相邻两个立体纹理之间的距离)w1和所述第二立体纹理120的线距w2各自独立的为1～150微米(具体可以为150微米、140微米、130微米、120微米、110微米、100微米、50微米、20微米、10微米、5微米、1微米等)；一些具体实施例中，所述第一立体纹理110的纹理深度h1和所述第二立体纹理120的纹理深度h2各自独立的为1～100微米(具体可以为100微米、80微米、50微米、40微米、30微米、20微米、15微米、10微米、9微米、8微米、7微米、6微米、5微米、4微米、3微米、2微米、1微米等)。在上述线宽、线距和深度范围内，双层立体纹理可以使得其反射光发生干涉作用，从而呈现特殊的摩尔纹外观，外观效果更立体和更炫丽，装饰效果更佳。
一些具体实施例中，，所述第一立体纹理110和所述第二立体纹理120在所述垂直方向的正投影的形状各自独立的为几何图形和不规则图形中的任意一种。具体的，所述几何图形可以包括圆形(参照图3，以第一立体纹理为例说明)、多边形(具体可以为三角形、四边新、五边形、六边形等等)(参照图4和图5，以第一立体纹理、正投影投影为四边形为例说明)、弓形和多弧形中的至少一种。而不规则图形则可以根据想要呈现的外观效果灵活设置，在此不再一一赘述。
一些具体实施例中，，第一立体纹理和第二立体纹理在垂直方向的正投影只要不完全重叠即可，具体的，第一立体纹理和第二立体纹理可以形状不同、尺寸不同或者排布方式不同，例如，可以第一立体纹理为多个平行设置的条状纹理，而第二立体纹理为多个阵列分布的点状纹理；或者第一立体纹理和第二立体纹理均为多个平行的条状纹理，但两者的线宽和线距不同；或者，第一立体纹理和第二立体纹理的形状和尺寸均为多个平行的条状纹理，两者条状纹理的长度方相交叉，例如相互垂直，具有45度夹角等等。
一些实施例中，参照图6，该壳体组件还可以包括：镀膜层20，所述镀膜层20设置在所述第一表面上；盖底油墨层30，所述盖底油墨层30设置在所述镀膜层20远离所述玻璃基体10的表面上。由此，结合镀膜层和盖底油墨层，可以使得壳体组件具有丰富绚丽的颜色，结合双层立体纹理的光学干涉作用，可以使得壳体组件呈现绚丽、立体的外观效果。
一些具体实施例中，镀膜层可以为单层结构，也可以为多层结构。一些具体实施例中，镀膜层的材料可以为二氧化硅、二氧化钛和五氧化二铌中的至少一种，例如二氧化钛和二氧化硅交替设置的多层结构等。盖底油墨层可以为具有预定颜色的油墨层，一些具体实施例中，可以为黑色油墨层等，由此遮光效果较好，利于实现更好看的外观效果，具体的，盖底油墨层可以为单层结构，也可以为多层结构，每层油墨层的具体成分、厚度可以相同也可以不同，例如油墨的具体成分可以为使用与电子设备壳体的常用油墨，厚度可以为10～15微米，盖底油墨层为多层结构时可以是采用相同的油墨多次涂覆形成，具体可以2～3次涂覆形成，每次涂覆3～5微米厚度。
一些具体实施例中，所述镀膜层与所述玻璃基体的折射率不同。由此，可以使得玻璃基体与镀膜层之间的界面更加明显，纹理作用更强，玻璃基体上的双层立体纹理的光学干涉作用更好，进而实现更加绚丽和立体的外观效果。可以理解，所述镀膜层与所述玻璃基体的折射率差值越大，两者之间的界面更清晰，双层立体纹理的干涉作用更强烈，一些具体实施例中，所述镀膜层与所述玻璃基体的折射率差值可以大于等于0.5，具体如0.5、0.6、0.7、0.8、0.9、1等。由此，壳体组件的外观效果更绚丽和立体，装饰效果更好。
在本公开的另一方面，本公开提供了一种制备壳体组件的方法。根据本公开的实施例，该方法包括：在玻璃的相对的两个表面上形成具有预定图案的干膜，得到待蚀刻玻璃；将所述待蚀刻玻璃浸入蚀刻液中预定时间，以得到玻璃基体，所述玻璃基体具有相对的第一表面和第二表面，所述第一表面具有蚀刻形成的微米级第一立体纹理，所述第二表面上具有蚀刻形成的微米级第二立体纹理，所述第一立体纹理在垂直方向上的正投影和所述第二立体纹理在所述垂直方向上的正投影不完全重叠，并使得第一立体纹理和第二立体纹理的反射光发生干涉；去除所述玻璃基体上的所述干膜。该方法可以快速、高效的制备获得具有双层立体纹理的壳体组件，步骤简单、操作容易、制作良率高，且得到的壳体组件可以形成特殊的摩尔纹外观，呈现出更炫更立体的外观装饰效果，同时长时间使用不易变形。同时可以理解，该方法可以用于制备前面所述的壳体组件。
一些具体实施例中，，在玻璃的相对的两个表面上形成具有预定图案的干膜可以包括：提供整层干膜，将预设图案菲林与整层干膜叠加后依次进行曝光和显影，获得曝光区域和未曝光区域；去除所述未曝光区域的干膜，得到具有预定图案的干膜；然后将具有预定图案的干膜贴合于玻璃相对的两个表面上。可以理解，可以在与菲林叠加之前，先将整层干膜形成在玻璃相对的两个表面上，具体的可以直接在玻璃的表面上喷涂形成干膜，也可以将已经制备好的干膜贴合在玻璃的表面上；也可以将菲林与整层干膜叠加 后，再将叠加产品贴合在玻璃相对的两个表面上，然后再进行曝光以及后续其他步骤。其中，可以采用电脑排版的方式制备预设图案菲林，该预设图案菲林具有精细纹理的效果。需要说明的是，为了保证双层立体纹理的干涉作用，玻璃相对的两个表面上干膜的预定图案不同。
可以理解，所述干膜主要起到保护玻璃的作用，具体为使得被干膜覆盖的部分不会在后续步骤中被蚀刻，可长时间耐蚀刻液攻击而不脱落、溶解。根据上述使用要求，干膜可以为感光耐酸膜，具体可以为高分子薄膜，可以由聚酰亚胺、液晶高分子聚合物或聚萘二甲酸乙二醇酯薄膜制备，在紫外光的照射下会交联固化，当用菲林遮蔽后，采用紫外线直接曝光，光照部分被固化，非光照部分仍未固化，未固化感光膜可通过显影去除，例如可以通过平板喷淋线进行显影，去除所述未曝光区域的干膜，显影液可以为质量浓度为0.5％～1％的碳酸钠溶液，从而在所述干膜上形成与预设图案菲林对应的预定图案。
一些具体实施例中，，在玻璃上形成预定图案干膜后，可以直接将待蚀刻玻璃浸入蚀刻液中进行蚀刻，以在未被干膜覆盖的位置形成立体纹理。具体的，采用的蚀刻液可以为质量浓度为5～10％的氢氟酸溶液。由此，蚀刻速度、蚀刻精度等均较好，得到的立体纹理表面平整、精度较高，壳体组件的外观效果较好。可以理解，蚀刻时间可以根据立体纹理尺寸、蚀刻液的蚀刻速度等进行调整，一些具体实施例中，蚀刻时间(即前面所述的预定时间)可为1～10分钟，具体如1分钟、2分钟、3分钟、4分钟、5分钟、6分钟、7分钟、8分钟、9分钟、10分钟等。
一些具体实施例中，，蚀刻之后，可以对玻璃基体进行清洗处理，以去除玻璃表面残留的蚀刻液。具体可以采用水对玻璃基体进行水洗或者超声清洗等，然后将清洗后的玻璃基体进行烘干，以便进行后续步骤。
一些具体实施例中，，去除所述玻璃基体上具有预定图案的干膜的方法没有特别限制，只要能够有效去除干膜、又不会损伤玻璃基体即可。一些具体实施例中，采用退镀工艺去除具有预定图案的干膜，具体步骤和参数可以参照常规技术进行，在此不再一一赘述。
一些具体实施例中，，该方法还可以包括：在所述第一表面上形成镀膜层；和在所述镀膜层远离所述玻璃基体的表面上形成盖底油墨层。
具体的，镀膜层可以通过物理气相沉积、化学气相沉积等方法形成，而盖底油墨层可以通过丝印、涂覆、打印、印刷等工艺形成，具体的操作步骤和参数可以参照常规技术进行，在此不再一一赘述。
在本公开的第三方面，本公开提供了一种电子设备。根据本公开的实施例，参照图7，该电子设备包括：前面所述的壳体组件100，所述壳体组件100限定出容纳空间；显示屏200，所示显示屏200设置在所述容纳空间中。该电子设备具有双层立体纹理，能够呈现特殊的摩尔纹外观，呈现出更炫更立体的外观装饰效果，且长时间使用不易变形，使用寿命更长。
在一些实施例中，该电子设备的具体种类没有特别限制，包括但不限于手机、平板电脑、可穿戴设备、游戏机、电视机等等，也可以理解，除了前面所述的壳体组件和显示屏之外，该电子设备还可以包括常规电子设备必要的部件和结构，以手机为例，还可以包括触控组件、指纹识别模组、照相模组、主板、储存器、电池等等，在此不再一一赘述。
