在本申请中，玻璃本体10的第一表面101上具有多个微米级的尖状凸起结构11，使得壳体组件100具有蒙砂效果，尖状凸起结构11与手指接触面积小，从而实现防指纹、防划伤、防眩光的效果；进一步的，尖状凸起结构11具有多个棱切面113，光线在棱切面113上发生反射，由于棱切面113角度不同，从而可以产生不同方向上的反射光，实现闪闪发 光的珠光效果，极大地丰富了壳体组件100的视觉效果，同时大部分的尖状凸起结构11的长宽相差不大，形貌尺寸均一性好，从而使得多个棱切面113之间的面积相差不大，在不同棱切面113产生的反射光强度相近，保证了尖状凸起结构11在不同角度下闪光强度的一致性，提高珠光效果的一致性和均匀性。相关技术中，壳体组件100仅仅具有蒙砂效果，表面几乎为圆形颗粒状的凸起，粒径小，容易产生漫反射，无珠光效果，需要配合珠光油墨使用，才能具有珠光；本申请提供的壳体组件100避免了珠光油墨的使用，节省了制作流程和成本，同时，第一表面101上的尖状凸起结构11形貌均匀性好，长宽相差不大，使得珠光效果在不同角度下都能够均匀、一致，提升了壳体组件100外观效果的均匀性和一致性。
可以理解的，玻璃本体10的第一表面101，即为壳体组件100的第一表面101，玻璃本体10的至少一个表面具有尖状凸起结构11。请参阅图1，玻璃本体10具有相对设置的第一表面101和第二表面102，其中第二表面102可以具有尖状凸起结构11，也可以不具有尖状凸起结构11，对此不作限定。可以理解的，本申请中“第一”、“第二”仅用于描述目的。

在本申请中，尖状凸起结构11的长度为尖状凸起结构11在第二表面102上的正投影的轮廓线上任意两点之间的间距的最大值；宽度为与长度方向垂直的方向上的，该正投影 的轮廓线上任意两点之间的间距的最大值；高度为尖状凸起结构11中尖端111至底部112之间的间距。由于尖状凸起结构11为微米级结构，尺寸较小，相对来说，尖状凸起结构11的长宽比为1：(0.6-3 1/2/2)，即

在本申请一实施方式中，三个棱切面113的面积比为1：(0.9-1)：(0.9:1)，棱切面113面积相近，从而在不同角度下的珠光效果一致性高。进一步的，三个棱切面113的面积比为1：(0.95-1)：(0.95:1)。在本申请中，棱切面113与第二表面102具有锐角夹角。在本申请一实施方式中，锐角夹角为10°-80°，从而使得棱切面113可以在更大角度范围内使入射光反射，产生闪闪发光的效果。进一步的，锐角夹角为30°-60°。具体的，锐角夹角可以但不限于为10°、20°、30°、40°、50°、60°、70°、80°等。在本申请中，相邻棱切面113之间具有夹角。在本申请一实施方式中，相邻棱切面113之间的夹角为钝角，从而能够极大地增强反射光的强度，提升珠光效果。
在本申请中，尖状凸起结构11为三棱锥和类三棱锥中的至少一种时，三个棱切面113两两相交，形成了三条棱边。可以理解的，此时尖状凸起结构11在第二表面102上的正投影为三角形，尖状凸起结构11的长度即为三角形的最大边长，宽度即为与最大边长对应的端点到最大边长的高度值。在本申请实施方式中，尖状凸起结构11具有第一棱边、第二棱边和第三棱边。在本申请一实施方式中，第一棱边、第二棱边和第三棱边的长度比为1：(0.8-1)：(0.8:1)。三条棱边长度相近，使得尖状凸起结构11中的棱切面113面积相近，从而在不同角度下的珠光效果一致性高。进一步的，第一棱边、第二棱边和第三棱边的长度比为1：(0.9-1)：(0.9:1)。具体的，第一棱边的长度可以但不限于为15μm-55μm。在本申请另一实施方式中，第一棱边与尖状凸起结构11的高度比值为1：(0.01-15)。从而使得尖状凸起结构11的形貌相对均匀一致，提升珠光效果的强度。进一步的，第一棱边与尖状凸起结构11的高度比值为1：(0.5-10)。

本申请还提供的了壳体组件的制备方法，该制备方法制备上述任一实施例的壳体组件100，包括：
提供蒙砂液，对玻璃本体前体的第一表面进行蒙砂处理并清洗，得到壳体组件，其中，蒙砂液包含氟硅酸，在蒙砂液中，与氟硅酸反应的阳离子为铵离子；第一表面上具有多个微米级的尖状凸起结构，尖状凸起结构包括尖端、底部，以及由尖端向底部延伸的三个棱切面，其中，在多个尖状凸起结构中，至少95％的尖状凸起结构的长宽比为1：(0.6-3 1/2/2)。
在本申请中，通过蒙砂液与玻璃本体前体反应生成氟硅酸盐晶体，氟硅酸盐晶体附着至玻璃本体前体的第一表面101，有晶体附着的位置会阻挡反应的进行，未有晶体附着的 区域会继续反应；蒙砂处理后，玻璃本体前体变为玻璃本体10，将附着有氟硅酸盐晶体的玻璃本体10的第一表面101进行清洗，得到了成型在玻璃本体10的第一表面101上的尖状凸起结构11，制得壳体组件100；尖状凸起结构11的形貌与生成的晶体形貌有关，本申请蒙砂液中阳离子为铵离子，从而使得绝大部分的氟硅酸盐为氟硅酸铵，氟硅酸铵为多棱锥形状，从而可以形成上述尖状凸起结构11。可以理解的，玻璃中可能存在含镁化合物、含钾化合物等，氟硅酸与这些物质也可以形成氟硅酸盐，相较于氟硅酸铵，这类氟硅酸盐含量很少，不会影响或改变氟硅酸铵晶体形貌以及最终形成的尖状凸起结构11的形貌。该壳体组件10的制备方法简单，工艺流程少，原料来源广泛，制备成本低，制得的壳体组件10不仅具有蒙砂、防指纹、防眩光、防滑等效果，还成型出闪闪发光的珠光效果，外观表现力强。
在本申请实施方式中，进行蒙砂处理之前，还可以包括对玻璃本体前体进行清洗处理。具体的，可以但不限于为对玻璃本体前体进行水洗和酸洗，以去除玻璃本体前体表面的脏污。在一实施例中，可以对玻璃本体前体进行水洗20s-30s，然后采用质量浓度为5％的氢氟酸对玻璃本体前体进行酸洗15s-20s，以去除玻璃本体前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的效果。
在本申请实施方式中，进行蒙砂处理之前，还可以包括对本体前体中不进行蒙砂处理的表面上设置保护层。从而对不进行蒙砂处理的表面进行保护，防止与蒙砂液进行接触。在一实施例中，通过在玻璃本体前体的一侧表面设置耐酸性油墨，形成保护层。进一步的，在蒙砂处理后，还包括去除保护层。
在本申请实施方式中，进行蒙砂处理之前，还可以包括将蒙砂液熟化24h-36h。通过熟化处理，使得蒙砂液成分混合均匀，并在此过程中使得蒙砂液内部缓慢产生出氢氟酸，有利于蒙砂处理的进行，同时相比于直接加入氢氟酸，通过间接方式生成的氢氟酸在蒙砂处理中，反应更加缓和安全。进一步的，熟化温度为20℃-50℃。更进一步的，熟化温度为25℃-40℃，时间为28h-35h。
在本申请实施方式中，进行蒙砂处理之前，还可以包括对玻璃本体前体和蒙砂液分别进行降温处理。从而可以减缓后续反应的速度，提升晶体分布的均匀性，以及形成的尖状凸起结构11的均匀性和一致性。在一实施例中，可以但不限于将4℃-10℃的水处理玻璃本体前体5s-20s，从而达到降温的目的。
在本申请实施方式中，按重量份数计，蒙砂液包括氟铵盐60份-100份、氟硅酸2.5份-10份、无机酸35份-50份，以及水30份-50份。蒙砂液中氟铵盐与无机酸生成氢氟酸，氢氟酸与玻璃中的二氧化硅反应生成氟硅酸(4HF+SiO 2→SiF 4+2H 2O)，氟硅酸与氟铵盐中的铵离子反应生成氟硅酸铵(H 2SiF 6+2NH 4 +→(NH 4) 2SiF 6+2H +)。在上述蒙砂液中，无机酸用于提供氢离子，氟铵盐用于提供氟离子和铵离子，以便于氢氟酸和氟硅酸铵的产生，从而可以使壳体组件100具有蒙砂和珠光效果；氟硅酸用于生成氟硅酸盐，同时还可以使初始形成的氟硅酸盐浓度达到饱和状态，从而使得氟硅酸盐结晶析出附着在玻璃表面。进一步的，重量份数计，蒙砂液包括氟铵盐70份-95份、氟硅酸3份-9份、无机酸38份-50份， 以及水38份-50份。在一实施例中，按重量份数计，蒙砂液中氟铵盐占70份-95份、75份-90份或80份-90份。具体的，蒙砂液中氟铵盐占60份、65份、75份、80份、85份、90份等。在另一实施例中，按重量份数计，蒙砂液中氟硅酸占3份-9份、4份-9份或5份-8份。具体的，蒙砂液中氟铵盐占3份、3.5份、4.5份、5.5份、6份、7份等。在又一实施例中，按重量份数计，蒙砂液中无机酸占38份-50份、40份-48份或42份-47份。具体的，蒙砂液中氟铵盐占39份、40份、42份、45份、48份、49份等。在又一实施例中，按重量份数计，蒙砂液中水占38份-50份、40份-48份或43份-47份。具体的，蒙砂液中水占39份、40份、41份、44份、45份、49份等。

在本申请中，蒙砂处理后，玻璃本体前体变为玻璃本体10，玻璃本体10的第一表面101上附着有氟硅酸盐；将玻璃本体10与蒙砂液分离，并对蒙砂处理的第一表面101进行清洗，去除氟硅酸盐晶体，即可得到壳体组件100。具体的，可以但不限于用水进行清洗处理。在一实施例中，水洗的温度为20℃-40℃，具体的，可以但不限于为25℃、30℃、35℃、38℃或40℃。
在本申请实施方式中，还可以对壳体组件100进行强化处理；也就是说，对玻璃本体10进行强化处理。在一实施例中，通过化学强化法对玻璃本体10进行强化处理。具体的，可以但不限于为将玻璃本体10进行盐浴，盐浴包括钠盐和钾盐中的至少一种，温度为400℃-500℃，时间为2h-10h。
在本申请实施方式中，还可以包括对壳体组件100进行CNC加工处理，以得到满足应用需求的壳体组件100。
本申请提供的制备方法简单、操作方便，能够得到蒙砂和珠光效果同时实现的壳体组件100，极大改善和提升了壳体组件100的外观效果，有利于其应用。
本申请还提供了一种电子设备，包括上述任一实施例的壳体组件100。可以理解的，电子设备可以但不限于为手机、平板电脑、笔记本电脑、手表、MP3、MP4、GPS导航仪、数码相机等。下面以手机为例进行说明。请参阅图6，为本申请一实施方式提供的电子设备的结构示意图，电子设备包括壳体组件100和主板。具有上述壳体组件100的电子设备不仅可以具有蒙砂效果，实现防指纹、防眩光、防滑，同时还具有珠光效果，显著提升电子设备的外观，满足用户需求。
实施例1
一种壳体组件的制备方法，包括：
将30重量份的NH 4HF 2、40重量份的NH 4F、5重量份的氟硅酸、50重量份的硝酸，以及50重量份的水混合搅拌均匀，并熟化处理24h。
在玻璃的第一表面上设置油墨保护层后，将玻璃置于上述蒙砂中进行蒙砂处理，处理温度为30℃，处理时间为4min。
将蒙砂处理后的玻璃取出，并进行水洗，以及去除油墨保护层得到壳体组件。
对比例1
一种壳体组件的制备方法，包括：
将30重量份的氟化钾、20重量份的硫酸，10重量份的高岭土，及40重量份的水混合搅拌均匀，并熟化处理24小时；其余步骤与实施例1的条件一致。
通过肉眼观察实施例1和对比例1制得的壳体组件，可以明显看出，实施例1的壳体组件不仅具有蒙砂效果，还具有珠光效果，在转动壳体组件时，会出现细腻的、闪闪发光的效果，而对比例1制得的玻璃仅仅具有蒙砂效果，无珠光产生。对实施例1制得的壳体组件进行拍照，结果如图7所示，可以看出其具有明显的珠光效果，闪光强度佳。
通过透光率仪(550nm波长)、雾度仪和粗糙度仪检测实施例1和对比例1制得的壳体组件性能。其中，实施例1制得的壳体组件的透过率为50％、雾度为80％，第一表面的表面粗糙度为1μm；对比例1制得的壳体组件的透过率为60％、雾度为50％，蒙砂面的表面粗糙度为0.3μm。
采用基恩士光学显微镜对实施例1和对比例1制得的壳体组件表面的微观结构进行检查，结果如图8和图9所示，其中，图8为实施例1制得的壳体组件的表面微观结构示意图，图9为对比例1制得的壳体组件的表面微观结构示意图。可以看出，实施例1制得的壳体组件的表面上具有多个尖状凸起结构，而对比例1制得的壳体组件的表面上具有多个球状颗粒，微观形貌具有很大差异，并且从图中还可以看出，凸起的尺寸也具有很大差异。
对实施例1和对比例1制得的壳体组件进行表1中所示的检测，检测结果如表2所示，可以看出，实施例1制得的壳体组件耐脏污、耐磨性能远远优于对比例1制得壳体组件，具有很好的应用前景。
