具体实施方式
下面详细描述本申请的实施例。下面描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。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。
本申请是基于发明人的以下发现和认识而完成的：
随着用户对电子设备外观效果越来越高的要求，丰富多样的装饰效果也被广泛的应用在电子设备壳体中，防眩光玻璃是利用蚀刻药水以喷淋的作业方式喷洒于玻璃之上，经过一段反应时间，蚀刻药水与玻璃发生蚀刻，使得玻璃表面粗糙度约为300nm，从而实现防眩光雾面的效果。但是实际使用中，相关技术中的蚀刻玻璃外观表现力较差，且手触摸起来感觉总体较弱。有鉴于此，发明人经过研究发现，可以通过对玻璃表面性质和形貌的控制和选择，使玻璃表面形成闪光的突起结构，从而可以使玻璃在具备防眩光、防指纹作用的同时，在光照下可以闪闪发光。
有鉴于此，在本申请的一个方面，本申请提供了一种壳体组件。根据本申请的实施例，参照图1，该壳体组件包括：玻璃本体10，所述玻璃本体10具有相对的第一表面11和第二表面12；所述第一表面11上具有多个凸起结构111，所述第一表面在光照下于所述凸起结构111处形成闪光点，其中，所述凸起结构满足以下条件的任意一种，所述凸起结构为尖状凸起结构；或者所述凸起结构包括至少一条棱。具体的，上述凸起结构具备折光和散光的功能，在光照下具有闪闪发光的外观效果，同时还可以实现防眩光、防指纹作用。
需要说明的是，上述尖状凸起结构为棱锥和类棱锥结构中的至少一种。由此，尖状突起结构使照射到第一表面的光线产生有效的镜面反射，形成闪光效果。其中，棱锥结构和类棱锥结构可以为三(类)棱锥、四(类)棱锥、五(类)棱锥等至少之一，这种多面体的尖状突起结构的每一面都存在镜面反射，形成闪光点，所以多种不同的棱锥结构可以使光线的面反射更加明显、强烈，进而使得壳体组件的闪光效果更加明显。需要说明的是，“类棱锥结构”是指类似棱锥结构的结构，比如类棱锥结构的顶部非尖状，而是面状，或者类棱锥结构的一个或多个表面为曲面等等。
需要说明的是，“凸起结构包括至少一条棱”是指凸起结构至少包括两个方向不同且相交的面，且两个面相交(或称为相连接)的位置处构成棱，该凸起结构具有类似钻石的形状，能够有效发生镜面反射，从而具有闪闪发光的外观效果。具体的，具有至少一条棱的凸起结构的形状包括但不限于棱柱(如三棱柱、四棱柱、五棱柱、六棱柱等)、棱台(如三棱台、方棱台、五棱台等)、立方体、八面体等等。
具体的，所述凸起结构可以构造为六方晶型、立方晶型、三方晶型和四方晶型中的至少一种，或者说凸起结构的形貌属于六方晶系晶体形貌、立方晶系晶体形貌、三方晶系晶体形貌和四方晶系晶体形貌中的至少一种。可以理解，六方晶系具有四个晶轴，即一个竖直轴(z轴)和三个水平横轴(x轴、y轴和u轴)，竖直轴与水平横轴的交交均为90度，三个水平横轴之间的夹角为60度，围绕z轴旋转一周，三个水平横轴可以重合6次。而立方晶系又称等轴晶系，其必定有四个三次对称轴的同时，不是还有三个相互垂直的四次轴，就是还有3个相互垂直的2次对称轴，此3个四次轴或2次对称轴即为晶体的3个结晶轴，三个结晶轴长度一样，且相互垂直；在晶体外形或宏观物性中能呈现出具有惟一高次三重轴或三重反轴特征对称元素的晶体归属于三方晶系，而在唯一具有高次轴的c轴主轴方向存在四重轴或四重反轴特征对称元素的晶体归属于四方晶系。具有上述晶型的凸起结构，在光照条件下闪光效果更佳，利于提高外观美观度。
需要说明的是，上述“凸起结构的形貌属于六方晶系晶体形貌、立方晶系晶体形貌、三方晶系晶体形貌和四方晶系晶体形貌中的至少一种”应做广义理解，即凸起结构的形貌并不 一定与六方晶系晶体形貌、立方晶系晶体形貌、三方晶系晶体形貌和四方晶系晶体形貌完全一致，只要凸起结构的形貌与六方晶系晶体形貌、立方晶系晶体形貌、三方晶系晶体形貌和四方晶系晶体形貌大致一致即可，允许一定的偏差存在。
具体的，第一表面11的表面粗糙度为0.6～3.2微米(具体如0.6微米、0.7微米、0.8微米、0.9微米、1微米、1.1微米、1.2微米、1.3微米、1.4微米、1.5微米、1.6微米、1.7微米、1.8微米、2.0微米、2.1微米、2.2微米、2.3微米、2.4微米、2.5微米、2.6微米、2.7微米、2.8微米、2.9微米、3微米、3.1微米、3.2微米等)。上述表面粗糙度范围，使得触摸时可以具有更明显的触感，手持感和立体感较好，还可以具有较好的防滑和防指纹的功能。
一些具体实施例中，所述第一表面的表面粗糙度可以为0.6～1.2微米。由此，较大的表面粗糙使光线在第一表面的镜面反射更加显著，进而进一步提升壳体组件的闪光效果；若表面粗糙度小于0.6，则不仅会相对降低防眩光和防指纹效果，而且还会降低壳体组件的闪光效果；若表面粗糙度大于1.2，则触感会更加明显。
一些具体实施例中，所述第一表面11的表面粗糙度为1.3～3微米(具体如1.3微米、1.4微米、1.5微米、1.6微米、1.7微米、1.8微米、2.0微米、2.1微米、2.2微米、2.3微米、2.4微米、2.5微米、2.6微米、2.7微米、2.8微米、2.9微米、3微米等)。由此，不仅能够增强闪光效果，且防眩光和防指纹效果增加，同时触感明显，防滑效果更佳。
具体的，所述第一表面的雾度可以为30％～85％(具体如30％、35％、40％、45％、50％、55％、60％、65％、70％、75％、80％、85％等)。在该雾度范围内，既能够实现较好的防眩光、防指纹效果，同时兼具闪闪发光的外观效果，使得壳体组件具有更加美观的外观效果。
一些具体实施例中，所述第一表面的雾度为30％～50％，比如30％、35％、40％、45％、50％。由此，壳体组件具有良好的防指纹和防眩光效果。另一些具体实施例中，所述第一表面的雾度为50％～85％，比如50％、55％、60％、65％、70％、75％、80％、85％等。由此，壳体组件的防指纹和防眩光效果更佳，同时和闪光效果能够形成更加强烈的对比，壳体组件能够提供更加强烈的视觉冲击。
一些具体实施例中，所述玻璃本体的透过率为90％～92％，具体如90％、90.5％、91％、91.5％、92％等。由此，壳体组件具有较高的透过率，外观表现力更强，能够实现更美观的外观效果。
一些实施例中，玻璃本体的透过率和雾度可以同时满足上述范围，由此，壳体组件能够同时实现高雾度和高透过率，在具有雾面效果的同时，通透性较好，能够实现特殊的外观效果。
具体的，所述凸起结构可以是利用蚀刻过程中形成的晶体形成的。具体的，对玻璃本体蚀刻过程中可以形成晶体附着在玻璃本体表面，形成有晶体的位置会阻碍蚀刻的进一步进行，而蚀刻液会沿着晶体的四周逐渐向内进行蚀刻，即蚀刻液沿着晶体的轮廓进行蚀刻，从而形成上述构造为预定晶型的凸起结构。
具体的，所述凸起结构的尺寸为1～110微米，具体可以为1-30微米，如1微米、5微米、8微米、10微米、12微米、15微米、18微米、20微米、22微米、25微米、28微米、30微米、40微米、50微米、60微米、70微米、80微米、90微米、100微米、110微米等。相邻两个所述尖状凸起结构之间的间隔距离可以为0～60微米，具体如1～20微米，如0微米、1微米、2微米、5微米、8微米、10微米、12微米、15微米、18微米、20微米、30微米、40微米、50微米、60微米等。该尺寸范围内，凸起结构切面表现为类似钻石的凸起状，具有更好的散光和反光效果，且能够提供较好的立体感和握持感。
需要说明的是，上述“凸起结构的尺寸”是指凸起结构在玻璃本体上的正投影的轮廓线上任意两点之间距离的最大值；“相邻两个凸起结构之间的间隔距离”是指相邻两个凸起结构在玻璃本体上的正投影的轮廓线上的两点之间距离的最小值。
具体的，所述凸起结构的高度为1.3～3.6微米，具体如1.3微米、1.5微米、1.8微米、2微米、2.2微米、2.5微米、2.8微米、3微米、3.2微米、3.5微米、3.6微米等。在该高度范围内，具有更明显的立体感，外观效果更佳。
具体的，所述凸起结构的形状包括雪花状、蜘蛛网状(参见图2，图2中示出了不同尺寸的蜘蛛网形状的尖状凸起结构)、松针状(参照图10)和树叶状(参照图11)中的至少一种。由此，可以具有不同的闪光效果，利于提高外观美观度。
具体的，本申请中可以采用的玻璃本体中可以含有氧化铝。进一步的，按照质量百分比计算，所述玻璃本体中氧化铝的含量大于20％，具体如20％、25％、30％、35％、40％等。由此，该玻璃本体具有更好的强度、耐磨性、易加工性，且厚度可以较薄，能够更好地满足电子设备壳体组件的使用要求。
具体的，本申请的玻璃本体的强度可以为560～600MPa(具体如560MPa、570MPa、580MPa、590MPa、600MPa等)；负载1Kg耐摩擦大于等于3000次(具体如3000次、3100次、3200次、3300次、3400次、500次、3600次、700次、3800次、3900次、4000次等)。说明本申请的该壳体组件可以具有较好的机械性能和耐磨性能，能够很好地满足电子设备领域的使用要求。
进一步的，除了前面所述的玻璃本体，壳体组件还可以包括光学镀膜层和盖底油墨层，其中，光学镀膜层设置在玻璃本体的第二表面上，盖底油墨层设置在光学镀膜层远离第一 表面的一侧。由此，光学镀膜层的设置可以有效提升壳体组件的外观光泽度和质感；盖底油墨层的设置可以有效保证壳体组件不透光，进而保证壳体组件的良好外观效果。
当然，本领域技术人员还可以根据对壳体组件的外观效果的设计需要，在第二表面的一侧设置其他外观装饰层，比如UV转印图案、色彩渐变图案等图案。
可以理解，该壳体组件可以为2D结构、2.5D结构或者3D结构，具体形状和尺寸可以根据电子设备的实际需求进行选择，在此不再过多描述。进一步的，该壳体组件可以为电子设备的后盖，中框，或者后盖和中框一体成型的3D壳体等等。
在本申请的另一方面，本申请提供了一种制备壳体组件的方法。根据本申请的实施例，参照图3，该方法包括：
S100：利用蚀刻液对玻璃本体的至少部分外表面进行蚀刻。
具体的，该蚀刻步骤中，蚀刻液可以与玻璃本体反应生成晶体，该晶体附着在玻璃本体表面，形成有晶体的位置会阻碍蚀刻的进一步进行，而蚀刻液会沿着晶体的四周逐渐向内进行蚀刻，即蚀刻液沿着晶体的轮廓进行蚀刻，从而形成凸起结构。
一些具体实施例中，上述凸起结构可以是通过氟硅酸钠形成的。具体的，氟硅酸钠可以直接由玻璃和蚀刻液反应生成，由此，制备简单，方便，成本较低。具体的，首先，玻璃中的二氧化硅可以与蚀刻液中的HF反应：
SiO 2+4HF＝SiF 4+H 2O，
具体反应机理为：
-Si-O-Si-+H+F -＝-Si-OH+Si-F；
接着，-Si-OH可以与HF继续反应：
Si(OH) 4+6HF＝H 2SiF 6+4H 2O；
其中，SiF 4一般条件下为气态，但不能全部挥发，有一部分会留在蚀刻液中，从而可以与蚀刻液中的HF以及氟化物发生如下反应：
4SiF 4+2HF+3H 2O＝3H 2SiF 6+H 2SiO 3
SiO 2+4HF＝SiF 4+H 2O
Al 2O 3+6HF＝2AlF 3+3H 2O
Na2O+2HF＝2NaF+H 2O
而蚀刻液中剩余的SiF 4与上述反应生成的氟化物继续反应：
SiF 4+2KF＝K 2SiF 6
SiF 4+2NaF＝Na 2SiF 6
SiF 4+2NH 4F＝(NH 4) 2SiF 6
在本申请的蚀刻液中，基于可与氟硅酸反应的阳离子的总摩尔数，钠离子的摩尔百分比大于或等于80％，比如80％、82％、84％、86％、88％、90％、91％、92％、93％、94％、95％、96％、97％、98％、99％、99.5％，即反应得到的氟硅酸盐大部分为多棱角形的氟硅酸钠，从而有效形成表面具有凸起结构的壳体组件；若钠离子的摩尔百分比小于80％，则第一表面具有较多的由氟硅酸铵和氟硅酸钾形成的球形凸起结构，而球形凸起结构主要使光线发生漫反射，并非是镜面反射，从而也就无法有效产生闪光效果。具体的，所述蚀刻液可以为氟硅酸钠的饱和溶液。由此，更加有利于氟硅酸钠晶体的形成，进而利于尖状凸起结构或者具有至少一个棱的凸起结构的形成，以保证实现闪光效果的外观。
进一步的，刻蚀液可以包括：10～30重量份(比如10重量份、14重量份、18重量份、22重量份、26重量份、30重量份)的NaF、30～50重量份(比如30重量份、34重量份、38重量份、42重量份、46重量份、50重量份)的NaHF 2、5～10重量份(比如5重量份、6重量份、7重量份、8重量份、9重量份、10重量份)的NH 4F、2.5～10重量份(比如2.5重量份、5重量份、5.5重量份、7.5重量份、10重量份)的氟硅酸、35～50重量份(比如35重量份、38重量份、40重量份、43重量份、45重量份、50重量份)的无机酸，及30～50重量份(比如30重量份、34重量份、38重量份、42重量份、46重量份、50重量份)的水。由此，时刻液中含有大量的钠离子，进而反应得到大量的氟硅酸盐，并附着在玻璃本体的表面，从而有利于形成尖状凸起结构；氟化铵作为缓冲剂，保持蚀刻液中pH值的稳定；无机酸提供氢离子，且与氟离子反应生成氢氟酸。
本领域技术人员可以理解，当蚀刻液是上述配方时蚀刻液中基于钠离子和铵离子的总摩尔数，钠离子的摩尔百分比大于或等于80％。
进一步，蚀刻液还可以包括：5～10重量份(比如5重量份、6重量份、7重量份、8重量份、9重量份、10重量份)的硫酸钡。由此，可以使蚀刻液处于悬浊液的状态，进而可以提高蚀刻液黏度，使蚀刻液在玻璃表面反应更加充分。
进一步的，在蚀刻处理之前，预先将蚀刻液进行熟化处理。由此，在熟化的过程中，蚀刻液中形成稳定的氢氟酸，以便于蚀刻处理的顺利进行。其中，熟化处理的具体方法可以根据实际需求灵活选择，在一些实施例中，熟化处理的方法为在60℃下放置一定时间(该时间即为熟化时间)。在一些实施例中，熟化处理的时间也可以根据实际需求灵活选择，比如熟化时间为24～36小时，比如24小时、28小时、32小时或36小时。
具体的，在进行所述蚀刻之前，还可以包括：对所述玻璃本体和蚀刻液分别进行降温处理。由此，一方面可以减缓蚀刻的速度，从而便于对蚀刻过程中的不同的化学反应过程进行控制，后续蚀刻步骤中反应速率降低，对异色、流痕等不良起到很好的抑制作用，可 以实现连续生产，另一方面低温更加利于氟硅酸钠晶体的析出和形成，进而更利于生成具有闪光效果的凸起结构。
一些具体实施例中，对所述玻璃本体进行降温是采用冷水进行的，包括但不限于采用冷水喷淋玻璃本体，或者将玻璃本体浸入冷水中进行降温。一个具体示例中，可以将玻璃本体浸入冷水中进行降温处理，如此，玻璃本体与冷水接触更加充分，利于热量传递，降温效果更好。一个具体示例中，采用3～8摄氏度(具体如3摄氏度、4摄氏度、5摄氏度、6摄氏度、7摄氏度、8摄氏度等)的冷水对所述玻璃本体降温10～15s(具体如10s、11s、12s、13s、14s、15s)等。由此，得到的低温玻璃具有合适温度，适于在后续蚀刻过程中生成凸起结构。
具体的，所降温处理后的蚀刻液的温度可以为5～10摄氏度，具体如5摄氏度、6摄氏度、7摄氏度、8摄氏度、9摄氏度、10摄氏度等。该温度范围内，更加易于氟硅酸钠晶体在玻璃表面形成，然后蚀刻液顺着氟硅酸钠晶体蚀刻下去以形成具有闪光效果的凸起结构。一些具体实施例中，在对蚀刻液进行降温处理时，可以持续对蚀刻液进行搅拌。由此，可以使得药水尽量保持均匀状态，有效避免蚀刻液沉降，从而解决蚀刻效果不好、不均匀等问题。
一些具体实施例中，该步骤具体可以包括以下步骤：将玻璃本体浸入3～8℃的冰水给玻璃降温10～15s，使得玻璃本体处于低温状态，然后对蚀刻液进行降温，并辅以搅拌，使得蚀刻液降温处于5～10℃的状态，呈现牛奶般浓稠状。
可以理解，在进行降温处理之前，还可以根据需要对玻璃本体进行清洁处理。具体的，可以对玻璃本体进行水洗和酸洗，以去除玻璃本体表面的脏污。一些具体实施例中，可以先对玻璃本体进行水洗20～30s，以清除玻璃表面残留的很少许的抛光粉等易去除的脏污，然后采用质量浓度为5％的氢氟酸对玻璃本体进行酸洗15～20s，以去除玻璃本体表面油污和较难去除的脏污，以达到整体而均匀的清洁和活化玻璃本体的效果。
具体的，上述蚀刻步骤中，参照图4，可以使所述玻璃本体10以30～45度(具体如30度、32度、35度、38度、40度、42度、45度等)的倾斜角α浸入所述蚀刻液中，所述倾斜角α为所述玻璃本体10与所述蚀刻液的液面21之间的夹角。以该倾斜角将玻璃本体浸入蚀刻液中，可以使得玻璃本体浸入蚀刻液的深度较小，便于操作，蚀刻液用量较少，利于节约成本，同时还利于凸起结构的形成。
具体的，上述蚀刻步骤中，所述玻璃本体浸入所述蚀刻液中后，使得所述玻璃本体在与所述蚀刻液的液面相平行的方向上摆动。通过玻璃本体的摆动可以避免蚀刻液沉降以及形成的晶体相互遮蔽，使得蚀刻更加均匀，保证形成的凸起结构的密度和均匀性。
具体的，所述蚀刻的时间可以为60～300秒(具体如60秒、70秒、80秒、90秒、100秒、110秒、120秒、130秒、140秒、150秒、160秒、170秒、80秒、190秒、200秒、210秒、220秒、230秒、240秒、250秒、260秒、270秒、280秒、90秒、300秒等)。由此，可以根据蚀刻液与玻璃本体反应速率的快慢确定蚀刻处理时间，在上述时间范围内，玻璃本体可以充分与蚀刻液反应，在表面均匀的附着一层氟硅酸钠，进而有利于得到凸起结构分布均匀的第一表面。另外，该蚀刻时间可以使得凸起结构具有合适的尺寸，获得更加均匀和美观的闪光外观效果的同时，具有相对较大的雾度和粗糙度，进而兼具防眩光功能、防指纹功能和较好的握持手感。
可以理解，在蚀刻处理之前，还可以包括：在除第一表面之外的玻璃本体的表面上形成保护层；对第一表面进行预清洁处理。由此，通过设置保护层，可以防止除了第一表面之外的玻璃本体的表面与蚀刻液接触；预清洁处理可以预先将第一表面的油渍等杂质去除，保证蚀刻处理的顺利进行以及蚀刻表面的均匀性。
进一步的，保护层的材料可以为油墨，如此，不仅可以有效防止玻璃本体的其它部位被蚀刻液腐蚀，而且油墨在蚀刻液中具有较佳的稳定性，不会参与反应，产生副作用；预清洁处理的方法没有特殊要求，只要可以清洁污渍，不损坏玻璃即可，比如可以采用不含氢氟酸的酸液或液氨进行清洗。
S200：对经过所述蚀刻的所述玻璃本体进行水洗。
该步骤中，通过水洗可以去除蚀刻步骤中形成的晶体，暴露出尖状凸起结构或具有至少一个棱的凸起结构。
具体的，水洗可以包括：对所述闪光玻璃依次进行常温水洗和温水洗。一些具体实施例中，所述温水洗采用的温水的温度为35～40摄氏度(具体如35摄氏度、36摄氏度、37摄氏度、38摄氏度、39摄氏度、40摄氏度等)。其中，常温水洗可以洗去玻璃表面残留的蚀刻液和结晶盐等，而温水可以具有更强的清洗能力，进一步清洁蚀刻之后的玻璃本体表面，去除残留的晶体。一些具体实施例中，可以在蚀刻后，常温水洗玻璃约20～30s，然后采用35℃～40℃的温水再次清洁玻璃表面20～30s。
进一步的，根据实际需要，温水洗后，可以将玻璃在水中插架，即将洗好的闪光玻璃插架到水中，以避免其受到酸气、酸液腐蚀。
具体的，该方法还可以包括：对经过所述蚀刻的所述玻璃本体进行强化处理。具体的强化后处理可以按照常规技术(如离子交换等)进行，在此不再一一赘述。由此，可以增强玻璃的表面应力，使其具有更好的机械强度。
可以理解，一些实施例中，该方法中形成的第一表面可以与前面描述的壳体组件中的 玻璃本体中的第一表面一致，即具有相同的特征和优点，在此不再一一详述。
具体的，该方法还可以包括对玻璃本体进行CNC加工、贴装饰膜片和镀防指纹膜中的至少一种。具体的，上述CNC加工、贴装饰膜片和镀防指纹膜和刻蚀玻璃本体中的步骤的先后顺序可以根据需要进行调整。一些具体实施例中，可以完成蚀刻步骤中，对玻璃进行CNC加工，以切掉临时孔位置处异色，塑造出摄像孔位，然后就进行强化增加玻璃强度，接着进行贴膜后镀防指纹膜以赋予壳体防指纹、疏水疏油的效果，再然后贴装饰膜片以对壳体进行装饰。进一步的，根据实际需要，还可以进行贴辅料、镜片等步骤。
本申请的该方法步骤简单、操作方便，能够有效在玻璃表面形成具有折光和散光效果的凸起结构，使得得到的玻璃在光照条件下具有闪闪发光的效果，同时兼具防眩光和防指纹效果，且该表面粗糙度范围使得玻璃具有较好的立体感和握持手感。
在本申请的又一方面，本申请提供了一种电子设备。根据本申请的实施例，该电子设备包括：前面所述的壳体组件、前面所述的方法制备获得的壳体组件；显示屏组件，所述显示屏组件与所述壳体组件相连，所述显示屏组件和所述壳体组件之间限定出安装空间；以及主板，所述主板设置在所述安装空间内且与所述显示屏组件电连接。该电子设备兼具闪光、防眩光、防指纹、立体感和较好的握持手感，能表现出更好的外观效果，利于提高用户体验。
