请参阅图7，图7是图4所示壳体组件100中的装饰件30的结构示意图。
本实施例中，装饰件30由素皮制备。素皮是指聚氨酯皮革，采用聚氨酯制备的装饰件30外观质感好、触感舒适、亲肤，具有较好的耐磨性能和抗老化性能，并且质量轻，有利于电子设备200的轻量化。在其它实施例中，装饰件30也可以由聚乙烯或聚氯乙烯等人造皮革制备得到。装饰件30也可以由动物真皮制备得到。动物真皮包括但不限于牛皮、羊皮、马皮和猪皮。由动物真皮制备的装饰件30外观质感好、触感舒适、亲肤，能够提升用户的使用体验。装饰件30还可以由硅胶制备得到。采用硅胶制备的装饰件30成本低，且化学稳定性好，机械强度高。装饰件30还可以由植物皮纹制备得到。植物皮纹由植物纤维制备得到。由植物皮纹制备的装饰件30具有优异的耐磨性能和抗老化性能，并且具有杀菌防霉、环保的优点。

请一并参阅图6至图8，图8是图2所示壳体组件100中的后盖1的结构示意图。
后盖1包括装饰件30和支撑件20，装饰件30安装于支撑件20的安装槽A，并与支撑件20固定连接。第一装饰段31与第一支撑段211正对，第二支撑段212与第二装饰段32正对，装饰件30的第二装饰件表面302朝向支撑件20的第一支撑件表面201。支撑件20对装饰件30起到支撑作用。这里的“正对”是指在壳体组件100的厚度方向，即Z方向的投影重合。
装饰件30的装饰件端面303与尾骨22的第一尾骨面221相对设置。本实施例中，装饰端面303抵接第一尾骨面221，也就是说，装饰件端面303与第一尾骨面221存在抵接力，从而可以保证装饰件端面303与第一尾骨面221连接的稳定性。在其它实施方式中，装饰件端面303与第一尾骨面221也可以通过粘接剂或者其它方式间接连接。或者，装饰件端面303与第一尾骨面221之间也可以存在很小的间隙，且间隙的尺寸为0～0.1mm。也就是，第一尾骨面221到装饰件端面303的距离为0～0.1mm。
其中，尾骨端面223与位于第二装饰段32的第一装饰件表面301平齐。也就是说，尾骨端面223和位于第二装饰段32的第一装饰件表面301之间无间隙，或者具有很小间隙(在装配公差范围内)，尾骨端面223和位于第二装饰段32的第一装饰件表面301平滑过渡。本申请的两个面之间平滑过渡，可以理解为，其中一个面与另一个面之间的落差小于或等于0.2mm，且该一个面的切平面与另一个面在相对位置处的切平面夹角小于或等于20度。或者，一个面与另一个面可以共面。换句话说，一个面与另一个面位于同一平面；或者，一个面与另一个面的切平面连续。在一些实施方式中，其中一个面与另一个面之间的落差也可以小于或等于0.03mm，以增加壳体组件的外观一致性和顺滑性。下文提到的“平滑过渡”均可做相同理解。
本实施例中，尾骨端面223和位于第二装饰段32的第一装饰件表面301的落差小于或等于0.03mm，且尾骨端面223的切平面与位于第二装饰段32的第一装饰件表面301的切平面的夹角小于或等于20度。在一种实施方式中，尾骨端面223和位于第二装饰段32的第一装饰件表面301也可以共面，且该面为曲面。当然，尾骨端面223和位于第二装饰段32的第一装饰件表面301也可以大致为曲面(允许有少量偏差)。本实施例中，尾骨22对装饰件30的第二装饰段32和装饰件端面303起到保护作用，可以防止装饰件30从靠近装饰件端面303的一端发生卷曲或损坏，影响后盖1的美观性和用户的使用体验感。同时，第一装饰件表面301和尾骨端面223之间平滑过渡且无间隙，可以减少刮手感并且进一步增加后盖1的美观性。
请参阅图4和图8，后盖1还包括第一粘接件40。第一粘接件40设置于于第一支撑件表面201和第二装饰件表面302之间，并粘接支撑件20和装饰件30，从而使装饰件30与支撑件20固定连接。本实施例中，第一粘接件40为热熔胶。热熔胶加热后熔融，在常温状态下即可完成固化，且粘接性能快，粘接强度高，并且粘接材料范围广。在其它实施例中，第一粘接件40也可以是双面胶或者其它胶水，只要能够实现装饰件30和支撑件20之间的固定连接即可。

支撑件20的第二支撑段212与中框10的第一侧面113层叠设置，并沿着第一侧面113弯曲方向朝向凹槽a内延伸。第二支撑段212与尾骨22连接的一端位于凹槽a内，并与避让部12相对设置。尾骨22部分位于凹槽a内，并沿着边框13的边框内表面132朝着远离凹槽a方向延伸，且第二尾骨面222与边框内表面132及边框顶面133相对。尾骨端面223与边框外表面131平滑过渡。可以理解为尾骨端面223与边框外表面131的落差小于或等于0.2mm，且尾骨端面223的切平面与边框外表面131的切平面的夹角小于或等于20度。示意性的，尾骨端面223与边框外表面131的落差也可以小于或等于0.03mm。在一种实施方式中，尾骨端面223与边框外表面131也可以共面，且该面为曲面，尾骨端面223向边框外表面131方向延伸。当然，尾骨端面223与边框外表面131也可以大致在一个曲面上(允许有少量偏差)。
本实施例中，通过在支撑件20设置尾骨22，且尾骨端面223和边框外表面131平滑过渡，以保证后盖1到中框10之间的顺滑过渡，增加壳体组件100美观性，减少刮手感。同时，通过在支撑件20设置尾骨22，可以减小后盖1与中框10之间的间隙，增加壳体组件100的美观性，提升用户的使用体验。
其中，尾骨22与边框13的边框顶面133之间具有第一间隙B，第一间隙B在Z方向的最大尺寸为L1。本实施例中，L1为0.5mm。在其它实施例中，L1也可以小于0.5mm，或者稍大于0.5mm。尾骨22与边框13之间的最小距离的尺寸为0.03mm-0.1mm。也就是，边框133与第二尾骨面222的最小距离为0.03mm-0.1mm。一种实施方式中，第一间隙B内设有胶水。位于第一间隙B内的胶水粘接尾骨22和边框13之间，以进一步增加尾骨22和边框13连接的稳定性，同时，也可以封闭第一间隙B，避免外部灰尘或水汽进入第一间隙B及凹槽a内。并且，通过在第一间隙B内设置胶水还可以进一步减少刮手感。
请参阅图2和图4，壳体组件100还包括第二粘接件50。第二粘接件50包括第一粘接面51和第二粘接面52，第一粘接面51和第二粘接面52相对设置。第二粘接件50位于中框10和支撑件20之间，且第一粘接面51与中框10的第一表面111粘接，第二粘接面52与支撑件20的第二支撑件表面202粘接，从而使支撑件20与中框10固定连接，进而使后盖1与中框10固定连接。本实施例中，第二粘接件50为泡棉胶。泡棉胶的基材包括但不限于乙烯-醋酸乙烯共聚物(EVA)或聚乙烯(PE)泡沫，基材相对两侧涂覆胶粘剂。泡沫基材具有弹性。作为泡棉胶的第二粘接件50可以起到缓冲作用，能够避免中框10和后盖1之间相互挤压，对中框10或者后盖1造成损坏。在其它实施例中，第二粘接件50也可以是双面胶或胶水，只要能实现支撑件20与中框10之间的固定连接即可。
请参阅图9，图9是图6所示支撑件20的制作流程图。
支撑件20的制作过程包括：
S1：提供一模具和原材料板；
S2：将原材料板置于模具内，压制原材料板形成基础支撑件，基础支撑件包括基础板和基础尾骨，基础尾骨位于基础板的外周缘，并与基础板连接；
S3：对基础尾骨进行切割，以形成支撑件。
请参阅图10a，图10a是采用图9所示制作方法制作基础支撑件过程中的部分结构示意图。
在S1中，模具包括上模具2和下模具3，上模具2盖合在下模具3上，且上模具2和下模具3之间具有成型槽4，成型槽4的形状和大小与基础支撑件20a的形状和大小一致。原材料板为纤维复合板预浸料。这里所说的“纤维复合板预浸料”是指用树脂基体在一定条件下浸渍连续纤维，制成的树脂基体与增强体的组合物。
在S2中，将原材料板置于成型槽4内，并对模具加热加压，以使原材料板形成基础支撑件20a。
请参阅图10b，图10b是采用图9所示制作方法制备的基础支撑件20a的部分结构示意图。
基础支撑件20a包括基础板和基础尾骨22a。基础板包括第一基础支撑段和第二基础支撑段212a。第二基础支撑段212a连接于第一基础支撑段的外周缘。第二基础支撑段212a相对第一基础支撑段朝同一侧弯曲。
基础尾骨22a与第二基础支撑段212a远离第一基础支撑段的一端连接。基础尾骨22a的延伸方向与第二基础支撑段212a的延伸方向的夹角为60度～120度。本实施例中，基础尾骨22a的延伸方向与第二基础支撑段212a的延伸方向的夹角为90度，在其它实施例中，基础尾骨22a的延伸方向与第二基础支撑段212a的延伸方向的夹角也可以大于90度或者小于90度。基础尾骨22a在其延伸方向尺寸大于0.6mm。
请继续参阅图10b，在S3中，沿第一切割线5对基础尾骨进行切割，以使基础支撑件20a形成支撑件20(如图6所示)。切割后的基础尾骨22a即形成支撑件20的尾骨22。本实施例中，采用数控切割的方式对基础尾骨22a进行切割，从而保证切割的精准性。这里所说的“数控切割”是指用于控制机床或设备的工件指令(或程序)，是以数字形式给定的一种新的控制方式。
在一种实施方式中，支撑件20也可以直接通过压制一步成型。此时，模具内的成型的形状和大小与支撑件20的形状和大小一致。从而可以简化制备工艺，提升支撑件20的尺寸的精准性。
请参阅图11，图11是本申请第一实施例提供的壳体组件100的第二种实施方式的部分结构示意图。
本实施方式与图2所示的实施方式不同之处在于，尾骨端面223由第一尾骨面221向第二尾骨面222方向倾斜，且尾骨端面223与第一尾骨面221之间的夹角为锐角。也就是说，尾骨端面223相对第一装饰件表面301朝向凹槽a内方向倾斜。尾骨22在对装饰件30的第二装饰段32和装饰件端面303起到保护作用的同时，还能减少尾骨22的凸出部分，进一步避免尾骨22的尾骨端面223出现刮手感，提升用户的使用体验。
请参阅图12和图13，图12是本申请第一实施例提供的壳体组件100的第三实施方式的部分结构示意图，图13是图12所示壳体组件100中的支撑件20的结构示意图。
与图2所示的第一种实施方式的不同之处在于，尾骨22还包括延伸体24。延伸体24与尾骨22的凸起c连接，并由凸起c背向支撑件本体21方向延伸。也就是说，延伸体24是在尾骨22的第二尾骨面222上凸出形成。延伸体24包括延伸体底面241和延伸体侧面242。延伸体侧面242与尾骨端面223连接，且延伸体侧面242与尾骨端面223朝向相同且平齐，可以理解为延伸体侧面242与尾骨端面223为同一个平面。
支撑件20与中框10组装后，延伸体底面241与边框顶面133平行，延伸体24朝向边框13方向延伸。当然，延伸体底面241也可以相对边框顶面133具有倾斜角度(在公差范围内)。延伸体侧面242与边框外表面131平滑过渡。可以理解为延伸体侧面242与边框外表面131的落差小于或等于0.2mm，且延伸体侧面242的切平面与边框外表面131的切平面的夹角小于或等于20度。示意性的，延伸体侧面242与边框外表面131的落差也可以小于或等于0.03mm。在一种实施方式中，延伸体侧面242与边框外表面131也可以共面。其中，延伸体24与边框13的边框顶面133之间具有第二间隙C，第二间隙C也就是延伸体底面241与边框顶面133之间的间隙。第二间隙C在Z方向的最大尺寸为L2。L2为0.05mm～0.1mm。本实施例中，L2为0.07mm。
如图14a和图14b所示，图14a是图2所示壳体组件100的部分结构示意图，图14b是图12所示壳体组件100的部分结构示意图。本申请中，通过设置延伸体24，可以在图2所示实施例的基础上进一步减小支撑件20与边框13之间的间隙，增加壳体组件100的美观性，同时减少灰尘和水汽进入支撑件20与边框13的缝隙内。
本实施例中，支撑件20的制作过程包括：
(1)提供一模具和原材料板；
(2)将原材料板置于模具内，压制原材料板形成基础支撑件20a，基础支撑件20a包括基础板和基础尾骨22a，基础尾骨22a分别位于基础板相对两端，并与基础板固定连接；
(3)对基础尾骨22a进行切割，以形成支撑件20。
请参阅图15a和图15b，图15a是制备图13所示支撑件20过程中的部分结构示意图，图15b是制备图13所示支撑件20过程中形成的基础支撑件20a的部分结构示意图。
在步骤(1)中，模具包括上模具2和下模具3，上模具2盖合在下模具3上，且上模具2和下模具3之间具有成型槽4，成型槽4的形状和大小与基础支撑件20a的形状和大小一致。原材料板为纤维复合板预浸料。这里所说的“纤维复合板预浸料”是指用树脂基体在一定条件下浸渍连续纤维，制成的树脂基体与增强体的组合物。
基础支撑件20a包括基础板和基础尾骨22a。基础板包括第一基础支撑段和第二基础支撑段212a。第二基础支撑段212a分别连接于第一基础支撑段的外周缘。第二基础支撑段212a相对第一基础支撑段朝同一侧弯曲。
基础尾骨22a包括第一部分221a、第二部分222a和第一连接部分223a，第一连接部分223a连接第一部分221a与第二部分222a之间，且第一部分221a的厚度小于第二部分222a的厚度，第一连接部分223a的厚度由第一部分221a到第二部分222a逐渐增大。第一连接部分223a与第一部分221a连接的一端厚度与第一部分221a的厚度相同，第一连接部分223a与第二部分22a连接的一端的厚度与第二部分222a的厚度相同。第一部分221a与第二基础支撑段212a固定连接，且基础尾骨22a的延伸方向与第二基础支撑段212a的延伸方向的夹角为60度～120度。本实施例中，基础尾骨22a的延伸方向与第二基础支撑段212a的延伸方向的夹角为90度。
请继续参阅图15b，在步骤(3)中，沿第一切割线5对基础尾骨22a进行切割，以使基础支撑件20a形成支撑件20(如图13所示)。其中，第一切割线5与基础尾骨22a的延伸方向垂直。也就是说，在步骤(3)中将第二部分222a切割去除即可得到尾骨22。
本实施例中，采用数控切割的方式对基础尾骨22a进行切割，从而保证切割的精准性。这里所说的“数控切割”是指用于控制机床或设备的工件指令(或程序)，是以数字形式给定的一种新的控制方式。
在一种实施方式中，支撑件20也可以直接通过压制一步成型。此时，模具内的成型的形状和大小与支撑件20的形状和大小一致。从而可以简化制备工艺，提升支撑件20的尺寸的精准性。

本实施方式与图12的第三实施方式的不同之处在于，延伸体24还包括连接面243，连接面243连接延伸体侧面242和延伸体底面241。本实施例中，连接面243为平面，且连接面243与Z方向平行。在其它实施例中，连接面243也可以是曲面。或者，连接面243也可以是倒角。通过设置连接面243，可以避免延伸体侧面242和延伸体底面241直接连接形成尖角，从而造成刮手感，影响用户的使用体验。
请一并参阅图19，图19是图18所示支撑件20的制备过程的结构示意图。
本实施例所示支撑件20可由图13中的支撑件20进一步沿第一辅助切割线7切割得到。其中，第一辅助切割线7位于延伸体24，并与Z方向平行，且第一辅助切割线7穿过延伸体24的延伸体侧面242的延伸体底面241，第一辅助切割线7切割后的切割面即为连接面243。
请参阅图20和图21，图20是本申请第二种实施例提供的壳体组件100的部分结构示意图，图21是图20所示壳体组件的分解结构示意图。
本实施例中，中框10的材质与第一实施例中的中框10的材质相同。中框10包括中框本体11和边框13。中框本体11为矩形板体。中框本体11包括第一表面111和第二表面112，第一表面111和第二表面112相对设置。边框13连接于中框本体11的外周缘，且边框13沿Z轴正方向延伸。边框13包括边框外表面131、边框内表面132和边框顶面133。边框外表面131和边框内表面132相对设置，且边框外表面131和边框内表面132均与Z方向平行。其中，边框外表面131与中框本体11的第二表面112垂直连接，边框内表面132与中框本体11的第一表面111垂直连接。边框顶面133与边框内表面132远离中框本体11的一端固定连接，并由边框内表面132朝向边框外表面141方向延伸。边框顶面133与边框内表面132的夹角为90度。当然，边框顶面133与边框内表面132之间的夹角也可以稍大于90度，或者稍小于90度。边框13还包括边框弧面134，边框弧面134连接于边框顶面133和边框外表面131之间。在这里，边框弧面134可以理解为边框外表面133的一部分。
边框13和中框本体11共同围合成收容槽D。其中，第一表面111即为收容槽D的底壁，边框内表面132即为收容槽D的侧壁。收容槽D用于安装后盖1。
本实施例中，支撑件20的材质与第一实施例中支撑件20的材质相同。支撑件20包括支撑件本体21和尾骨22。
请一并参阅图22，图22是图21所示壳体组件100中的支撑件20的结构示意图。支撑件本体21包括第一支撑段211和第二支撑段212。第二支撑段212连接于第一支撑段211的外周缘。第一支撑段211包括第一面203和第二面204，第一面203和第二面204相对设置。第二支撑段212包括第三面205和第四面206，第三面205和第四面206相对设置。其中，第一面203和第三面205共同组成第一支撑件表面201，且第一支撑件表面201为平面。第二面204和第四面206共同组成第二支撑件表面202，且第二支撑件表面202为平面。也就是说，支撑件本体21为矩形板状结构。
尾骨22连接于支撑件本体21的外周缘，且尾骨22与第一支撑件表面201垂直。也就是说，尾骨22沿Z轴正方向延伸。尾骨22包括围骨本体b和凸起c。围骨本体b与第二支撑段212连接，凸起c与围骨本体b连接，且凸起c凸出于第三面205。需要说明的是，本实施例中，支撑件本体21、围骨本体b和凸起c为一体成型件，图22中的虚线仅为了描述方便，实际是不存在。
尾骨22还包括第一尾骨面221、第二尾骨面222和尾骨端面223。其中，第一尾骨面221与第二尾骨面222相对设置，第二尾骨面222在Z方向的高度低于第一尾骨面221在Z方向的高度。也就是说，第二尾骨面222远离支撑件本体21的一端位于第一尾骨面221远 离本体的一端的Z轴负方向位置。尾骨端面223连接第一尾骨面221和第二尾骨面222之间。本实施例中，尾骨端面223为斜面，且尾骨端面223与第一尾骨面221的夹角为锐角，与第二尾骨面222的夹角为钝角。即尾骨端面223由第一尾骨面221向第二尾骨面222方向倾斜。在其它实施例中，尾骨端面223也可以是曲面。
支撑件本体21和尾骨22共同围合成安装槽A。其中，第一支撑件表面201即为安装槽A的底壁，尾骨22的第一尾骨面221即为安装槽A的侧壁。安装槽A用于安装装饰件30。
请继续参阅图21，装饰件30的材质与第一实施例中的装饰件30的材质相同。本实施例中，装饰件为平直板状结构。装饰件30包括第一装饰件表面301、第二装饰件表面302和装饰件端面303。其中，第一装饰件表面301和第二装饰件表面302相对设置，且第一装饰件表面301和第二装饰件表面302均与X方向及Y方向平行。装饰件端面303位于第一装饰件表面301外周缘，并连接于第一装饰件表面301和第二装饰件表面302之间。本实施例中，装饰件端面303与X方向和Y方向垂直。也就是，装饰件端面303均与第一装饰件表面301和第二装饰件表面302垂直。
请一并参阅图20和图21，装饰件30安装于支撑件20的安装槽A，并与支撑件20固定连接。其中，装饰件30的第二装饰件表面302朝向支撑件20的第一支撑件表面201，装饰件端面303与第一尾骨面221连接。本实施例中，装饰端面303抵接第一尾骨面221。在其它实施方式中，装饰件端面303与第一尾骨面221也可以通过粘接剂或者其它方式间接连接。或者，装饰件端面303与第一尾骨面221之间也可以存在很小的间隙(在公差范围内)。
本实施例中，尾骨端面223与第一尾骨面221连接的一端与第一装饰件表面301在Z方向平齐，尾骨22对装饰件30和装饰件端面303起到保护作用，可以防止装饰件30从靠近装饰件端面303的一端发生卷曲或损坏，影响后盖1的美观性和用户的使用体验感。并且，装饰件端面303与第一尾骨面221之间无间隙，或者具有很小的间隙(在装配公差范围内)，从而可以防止灰尘或水汽进入支撑件20和装饰件30之间，影响后盖1的装配稳定性。同时，第一装饰件表面301和尾骨端面223之间平滑过渡且无间隙，可以减少刮手感并且进一步增加后盖1的美观性。
请继续参阅图20和图21，后盖1还包括第一粘接件40。第一粘接件40设置于第一支撑件表面201和第二装饰件表面302之间，并粘接装饰件30与支撑件20，从而使装饰件30与支撑件20固定连接。本实施例中，第一粘接件40为热熔胶。热熔胶加热后熔融，在常温状态下即可完成固化，且粘接性能快，粘接强度高，并且粘接材料范围广。在其它实施例中，第一粘接件40也可以是双面胶或者其它胶水，只要能够实现装饰件30和支撑件20之间的固定连接即可。
后盖1安装于中框10的收容槽D内，并与中框10固定连接。其中，支撑件本体21与中框10的中框本体11正对，尾骨22与边框13相对。支撑件20的第二支撑件表面202朝向中框10的第一表面111，第二尾骨面222朝向边框内表面132。
本实施例中，通过在支撑件20设置尾骨22，可以减小后盖1与中框10之间的间隙，增加壳体组件100的美观性。
其中，尾骨22的第二尾骨面222与边框13的边框内表面132之间具有第一间隙B，第一间隙B在X方向的最大尺寸为0.5mm。在其它实施例中，第一间隙B在X方向的最大尺寸也可以小于0.5mm，或者稍大于0.5mm。
一种实施方式中，第一间隙B内设有胶水。位于第一间隙B内的胶水粘接尾骨22和边框13之间，以进一步增加尾骨22和边框13连接的稳定性，同时，也可以封闭第一间隙B，避免外部灰尘或水汽进入第一间隙B内。并且，通过在第一间隙B内设置胶水还可以进一步减少刮手感。
请继续参阅图20和图21，壳体组件100还包括第二粘接件50。第二粘接件50包括第一粘接面51和第二粘接面52，第一粘接面51和第二粘接面52相对设置。第二粘接件50位于中框10和支撑件20之间，且第一粘接面51与中框10的第一表面111粘接，第二粘接面52与支撑件20的第二支撑件表面20粘接，从而使支撑件20与中框10固定连接，进而使后盖1与中框10固定连接。
本实施例中，第二粘接件50为泡棉胶。泡棉胶的基材包括但不限于乙烯-醋酸乙烯共聚物(EVA)或聚乙烯(PE)泡沫，基材相对两侧涂覆胶粘剂。泡沫基材具有弹性。作为泡棉胶的第二粘接件50可以起到缓冲作用，能够避免中框10和后盖1之间相互挤压，对中框10或者后盖1造成损坏。在其它实施例中，第二粘接件50也可以是双面胶或胶水，只要能实现支撑件20与中框10之间的固定连接即可。
请参阅图23和图24，图23是本申请第二实施例提供的壳体组件100的另一种实施方式的部分结构示意图。图24是图23所示壳体组件100中的支撑件20的结构示意图。
与图20所示壳体组件100的不同之处在于，尾骨22还包括延伸体24，延伸体24与凸起c连接，并由凸起c背向支撑件本体21方向延伸。尾骨22包括第一尾骨面221、第二尾骨面222和尾骨端面223。第一尾骨面221与第二尾骨面222相对设置，且第一尾骨面221与第二尾骨面222在Z方向平齐。尾骨端面223与第一尾骨面221连接，且尾骨端面223与X方向平行。延伸体24是在尾骨22的第二尾骨面222上凸出形成。延伸体24包括延伸体底面241和延伸体侧面242。延伸体侧面242与尾骨端面223连接，延伸体底面241的相对两端分别连接延伸体侧面242和第二尾骨面222。
本实施例中，延伸体底面241沿X方向的尺寸均为0.08mm～0.2mm。也就是，延伸体24凸出于第二尾骨面222的最大尺寸为0.08mm～0.2mm。后盖1安装于中框10时，延伸体24由尾骨22朝向边框13方向延伸，且延伸体24的延伸体底面241与边框13的边框顶面143相对设置。延伸体24对第一间隙B起到遮挡作用，可以避免外部的灰尘或水汽进入第一间隙B，影响后盖1与中框10连接的稳定性。同时，也可以增加壳体组件100的美观性。
本实施方式中，延伸体侧面242为斜面。在其它实施方式中，延伸体侧面242也可以是曲面。当延伸体侧面242为曲面时，延伸体侧面242与边框弧面134平滑过渡。可以理解为延伸体侧面242与边框弧面134的落差小于或等于0.2mm，且延伸体侧面242的切平面与边框弧面134的切平面的夹角小于或等于20度。示意性的，延伸体侧面242与边框弧面134的落差也可以小于或等于0.03mm。在一种实施方式中，延伸体侧面242与边框弧面134也可以共面，且该面为曲面，延伸体侧面242向边框弧面144方向延伸，并与边框弧面134平滑过渡。从而可以增加壳体组件100的美观性和平滑度，较少壳体组件100的刮 手感，提升用户的使用体验。当然，延伸体侧面242与边框弧面134也可以大致在一个曲面上(允许有少量偏差)。
一种实施方式中，延伸体24还包括连接面243。连接面243连接延伸体侧面242和延伸体底面241之间。本实施例中，连接面243为平面，且连接面243与Z方向平行。在其它实施例中，连接面243也可以是曲面。或者，连接面243也可以是倒角。通过设置连接面243，可以避免延伸体侧面242和延伸体底面241直接连接形成尖角，从而造成刮手感，影响用户的使用体验。
本实施例中，支撑件20的制作过程包括：
(1)提供一模具和原材料板；
(2)将原材料板置于模具内，压制原材料板形成基础支撑件，基础支撑件包括基础板和基础尾骨，基础尾骨位于基础板的外周缘，并与基础板连接；
(3)对基础尾骨进行切割，以形成支撑件20。

如图25b所示，基础支撑件20a包括基础板和基础尾骨22a。基础尾骨22a包括第一部分221a和第二部分222a，第一部分221a与第二部分222a连接，且第一部分221a与第二部分222a的夹角为90度。第一部分221a与基础板的一端固定连接，且第一部分221a的延伸方向与基础板的表面夹角为90度，第二部分222a的延伸方向与基础板的表面平行，且第二部分222a朝远离基础板方向延伸。
在步骤(3)中，沿第一切割线9对基础尾骨22a进行切割，以使基础支撑件20a形成支撑件20(如图24所示)。其中，第一切割线9位于第二部分222a，并与X轴正方向的夹角为锐角。基础尾骨22a切割后形成支撑件20的尾骨22。
本实施例中，采用数控切割的方式对基础尾骨22a进行切割，从而保证切割的精准性。这里所说的“数控切割”是指用于控制机床或设备的工件指令(或程序)，是以数字形式给定的一种新的控制方式。
在一种实施方式中，步骤(3)中，沿第一切割线9对基础尾骨22a进行切割完成之后，还可以沿第一辅助切割线对基础尾骨进行切割，以使最后得到的支撑件20的延伸体24包括连接面243。
在一种实施方式中，支撑件20也可以直接通过压制一步成型。此时，模具内的成型的形状和大小与支撑件20的形状和大小一致。从而可以简化制备工艺，提升支撑件20的尺寸的精准性。
请参阅图26a和图26b，图26a是本申请第三种实施例提供的壳体组件的部分结构示意图，图26b是图26a所示壳体组件另一角度的部分结构示意图。
与图2所示实施例不同之处在于，支撑件20包括支撑件本体21和尾骨22。尾骨22 包括两个第一子尾骨25和两个第二子尾骨26。第二支撑段212包括两个第一子支撑段2121和两个第二子支撑段2122，且第一子支撑段2121相较于第一支撑段211弯曲。也就是说，第二支撑段212在X方向的相对两端相较于第一支撑段211朝向中框10方向弯曲，而第二支撑段212在Y方向的相对两端为平直状。两个第一子支撑段2121连接于第一支撑段211沿X方向的相对两端，一个第一子尾骨25连接于一个第一子支撑段2121远离第一支撑段211的一端。两个第二子支撑段2122连接于第一支撑段211沿Y方向的相对两端，一个第二子尾骨26连接于一个第二子支撑段2122远离第一支撑段211的一端。两个第一子尾骨25和两个第二子尾骨26首尾连接形成尾骨22，且两个第一子尾骨25和两个第二子尾骨26为一体成型。本实施例中，每一第一子尾骨25与相邻的第二子尾骨26之间可以通过倒角连接，以使第一子尾骨25与相邻的第二子尾骨26之间的平滑过渡。
装饰件30包括第一装饰段31和第二装饰段32，第二装饰段32分别连接于第一装饰段31的外周缘，且位于第一装饰段31沿X方向相对两端的第二装饰段32相较于第一装饰段31弯曲，位于第一装饰段31沿Y方向相对两端的第二装饰段32为平直状。装饰件30包括两个第三端面304和两个第四端面305。两个第三端面304分别位于装饰件30沿X方向相对两端，两个第四端面305分别位于装饰件30沿Y方向的相对两端。
装饰件30安装于支撑件20，并与支撑件20固定连接。其中，第一装饰段31与第一支撑段211正对，第二装饰段32与第二支撑段212正对。两个第三端面303分别与两个第一子尾骨25连接，两个第四端面305分别与两个第二子尾骨26连接。
本实施例中，第一子尾骨25对装饰件30的第二支撑段212和第三端面304起到保护作用，可以防止装饰件30从靠近第三端面304的一端发生卷曲或损坏。第二子尾骨26对第一装饰段31和第四端面305起到保护作用，可以防止装饰件30从靠近第四端面305的一端发生卷曲或损坏，影响后盖1的美观性和用户的使用体验感。
其中，支撑件20安装于中框10，并与中框10固定连接。通过在支撑件20设置尾骨22，可以减小后盖1与中框10之间的间隙，增加壳体组件100的美观性。
请参阅图27a和图27b，图27a是本申请第三种实施例提供的壳体组件的另一种实施方式的部分结构示意图，图27b是图27a所示壳体组件另一角度的部分结构示意图。
本实施例中，尾骨22还包括两个第一子延伸体27和两个第二子延伸体28。一个第一子延伸体27连接于一个第一子尾骨25的凸起，并由对应的凸起背向支撑件本体21方向延伸。一个第二子延伸体28连接于一个第二子尾骨26的凸起，并由第二子尾骨26背向支撑件本体21方向延伸。
支撑件20与中框10组装后，第一延伸体27朝向对应的边框13延伸，且每一第一延伸体27与对应的边框13之间的间隙在Z方向的最大尺寸为0.05mm～0.1mm。本实施例中，每一第一延伸体27与对应的边框13之间的间隙在Z方向的最大尺寸为0.05mm。通过设置第一延伸体27，可以进一步减小支撑件20与边框13之间的间隙，增加壳体组件100的美观性。
第二延伸体28朝向边框13方向延伸。第二延伸体28对支撑件20与边框13之间的间隙起到遮挡作用，可以避免外部的灰尘或水汽进入间隙内，影响后盖与中框10连接的稳定性。同时，也可以增加壳体组件100的美观性。
在其它实施例中，第二支撑段的任意一部分都可以相较于第一支撑段弯曲。例如，第二支撑段沿X方向的其中一端相较于第一支撑段弯曲，第二支撑段沿X方向的另一端以及第二支撑段沿Y方向的相对两端均为平直状。
以上，仅为本申请的部分实施例和实施方式，本申请的保护范围不局限于此，任何熟知本领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
