Description

一种后盖、壳体及电子设备

技术领域
本申请涉及电子设备技术领域，尤其涉及一种后盖、壳体及电子设备。
背景技术
随着消费类电子产品的日新月异，各品牌的产品竞争激烈，消费者对于电子产品的要求也越来越高，除了电子产品的硬件规格，消费者也非常看重电子产品的外观设计。当具有3D效果的后盖应用于电子产品后，广泛受到消费者的喜爱。
发明内容
本申请提供一种后盖、壳体及电子设备，可使后盖呈现3D效果。
第一方面，提供一种后盖，包括平板部和弧形部，弧形部至少设置于平板部的相对两侧边缘处，与平板部固定连接；平板部包括玻璃板；弧形部的材料与玻璃板的材料不同。通过使该后盖包括平板部和弧形部，并采用玻璃板作为平板部，可最大化保留玻璃本身效果及性能，且可使后盖呈现3D效果，赋予电子设备外观更圆润、灵气的特征，具有较好的用户体验；在此基础上，相对现有3D玻璃需要整体进行拉伸，拉伸弧度以及弧面高度受到限制，由于本申请的弧形部与平板部的材料不同，在制作弧形部时不会受到平板部的作用力，因此，容易形成所需弧度的弧形部，可大幅提升后盖的生产产能，而且，通过合理选择常规弧形部的材料，还可降低后盖的生产成本。
结合第一方面，在第一方面的第一种可能的实现方式中，玻璃板为2.5D玻璃板。由于2.5D玻璃板没有突出的棱角，不容易受到其他物体的撞击，从而可以减少后盖被撞坏概率，而且能够使后盖外观面更具视觉张力。
结合第一方面，在第一方面的第二种可能的实现方式中，在平板部的任一侧边缘均设置弧形部。当弧形部围绕平板部的边缘一圈设置时，可为后盖提供四周均为弧形的轮廓，从而可以提升后盖的整体外观一致性，而且，在实际使用过程中还可以方便用户从各个角度抓握，均可以具有加好的抓握体验。

结合第一方面的第四种可能的实现方式至第六种可能的实现方式中的任一种，在第一方面的第七种可能的实现方式中，弧形部包括第一塑胶层。由于作为塑胶层的材料容易加工，可保证形状、厚度难以控制的弧形部具有较高的加工精度，而且可使弧形部的壁厚不均，使其内表面具有多样化的结构特征，从而可以满足不同产品的需求。
结合第一方面的第五种可能的实现方式或第六种可能的实现方式，在第一方面的第八种可能的实现方式中，弧形部包括由外至内依次层叠设置的IML膜片、第二粘接层、第二塑胶层；IML膜片设置有印刷层。相对后盖整体由IML工艺制成，存在表面硬度不高，无法满足用户使用需求的问题，本申请由于平板部采用玻璃板，因此，可大大提高后盖整体表面的硬度。而且，由于弧形部还包括第二塑胶层，可使弧形部的壁厚不均，使其内表面具有多样化的结构特征。
结合第一方面的第五种可能的实现方式或第六种可能的实现方式，在第一方面的第九种可能的实现方式中，弧形部包括由外至内依次层叠设置的表面硬化层、PMMA和PC复合层、油墨层。由于PMMA和PC复合层本身材料强度较强，再加上表面硬化层，可使其表面性能较高；而且，由于PMMA和PC复合层本身材质透过率较好，因此，可具有高透过率。

结合第一方面的第九种可能的实现方式，在第一方面的第十一种可能的实现方式中，弧形部还包括依次设置于油墨层远离PMMA和PC复合层一侧的第三粘接层和第三塑胶层。一方面，由于第三塑胶层的存在，可实现弧形部壁厚不均，内部结构特征多样化的特征，以适应不同架构的产品的需求；另一方面，可具有高质感、高韧性、高硬度的特点。
结合第一方面的第五种可能的实现方式或第六种可能的实现方式，在第一方面的第十二种可能的实现方式中，平板部还包括设置于玻璃板内侧的第一镀膜层；弧形部还包括第二镀膜层，第二镀膜层和第一镀膜层的材料相同。可使弧形部实现玻璃质感，从而使弧形部视觉上具有与平板部相同的质感，使得本申请的后盖整体形成仿3D玻璃效果。

具体实施方式
本申请提供一种后盖，如图1-5所示，包括平板部10和弧形部20，弧形部20至少设置 于平板部10的相对两侧边缘处，与平板部10固定连接；平板部10包括玻璃板；弧形部20的材料与玻璃板的材料不同。
可以理解的是，当本申请的后盖应用于不用类型电子产品时，根据具体的产品，在后盖上可设置例如通孔、盲孔、卡扣等结构。
示例的，当本申请的后盖应用于手机时，如图6所示，该后盖上可设置摄像孔31、闪光灯孔32、激光感应器33、指纹识别开口34等，此外，在后盖的内表面上还可设置其他结构，以与手机的模组相匹配。其中，内表面是相对后盖的外观面而言的，而外观面顾名思义是从外观上可以观察到的表面。
需要说明的是，第一，在弧形部20仅设置于平板部10相对两侧边缘处时，可根据该后盖所应用的电子设备的使用特点，将弧形部20设置在该电子设备通常使用状态下(例如竖直状态下)的平板部10的左右两侧，以最大化的呈现三维(Three-dimensional,3D)弧面效果，且具有较好的抓握体验。
第二，对于弧形部20与平板部10的连接方式，以不影响外观的美观为准。
第三，在选择弧形部20的材料时，可选择易于形成弧形的常规材料，具体在此不做限定。
第四，图1-5仅示意出后盖的整体形状，对于后盖上的具体结构并未体现。
本申请提供一种后盖，通过使该后盖包括平板部10和弧形部20，并采用玻璃板作为平板部10，可最大化保留玻璃本身效果及性能，且可使后盖呈现3D效果，赋予电子设备外观更圆润、灵气的特征，具有较好的用户体验；在此基础上，相对现有3D玻璃需要整体进行拉伸，拉伸弧度以及弧面高度受到限制，由于本申请的弧形部20与平板部10的材料不同，在制作弧形部20时不会受到平板部10的作用力，因此，容易形成所需弧度的弧形部20，可大幅提升后盖的生产产能，而且，通过合理选择常规弧形部20的材料，还可降低后盖的生产成本；此外，相对现有3D玻璃存在炫光膜贴合问题，本申请在贴合炫光膜时可仅贴合于平板部10，从而不会出现炫光膜贴合不好的问题。
可选的，作为平板部10的玻璃板为2.5D玻璃板。
2.5D玻璃板，即为，边缘呈向下弯曲的弧面的玻璃板。
由于2.5D玻璃板没有突出的棱角，不容易受到其他物体的撞击，从而可以减少后盖被撞坏概率，而且能够使后盖外观面更具视觉张力。
可选的，如图3-图5所示，在平板部10的任一侧边缘均设置弧形部20。即，弧形部20围绕平板部10的边缘一圈设置。
当弧形部20围绕平板部10的边缘一圈设置时，可为后盖提供四周均为弧形的轮廓，从而可以提升后盖的整体外观一致性，而且，在实际使用过程中还可以方便用户从各个角度抓握，均可以具有加好的抓握体验。
进一步可选的，如图3所示，平板部10包括第一边缘11、第二边缘12、第三边缘13和第四边缘14，第一边缘11和第二边缘12相对设置，第三边缘13和第四边缘14相对设置；如图4所示，分别位于第一边缘11和第二边缘12处的弧形部20对称设置；如图5所示，分别位于第三边缘13和第四边缘14处的弧形部20对称设置。基于此，可使后盖更具美感。
可选的，如图4和图5所示，弧形部20与平板部10一体成型。即，在无需连接结构的情况下，弧形部20与平板部10无缝连接。
具体的，在工艺上可采用一体成型工艺，形成与平板部10无缝连接的弧形部20。
通过使弧形部20与平板部10一体成型，一方面，工艺上较为简单且可采用成熟工艺，成本较低，另一方面，弧形部20与平板部10配合的精度较高，外观上无缝隙更美观。
在弧形部20与平板部10一体成型的基础上，可选的，如图4和图5所示，弧形部20包括第一塑胶层21。
塑胶层的材料可以是树脂材料，例如聚碳酸酯、丙烯腈-丁二烯-苯乙烯共聚物(ABS树脂)、聚苯乙烯(PS)、聚氯乙烯(PVC)、聚碳酸酯(PC)、聚甲基丙烯酸甲酯(PMMA)等热塑性树脂。
其中，可采用嵌件成型(Insert molding)工艺，将平板部10作为嵌件，形成与平板部10无缝连接的弧形部20。
由于作为第一塑胶层21的材料容易加工，可保证形状、厚度难以控制的弧形部20具有较高的加工精度，而且可使弧形部20的壁厚不均，使其内表面具有多样化的结构特征，从而可以满足不同产品的需求。此外，根据需要可通过模具表面抛光使弧形部20做出亮面效果，也可通过调节第一塑胶层21材料中粒子本身颜色及透过率，使弧形部20达到不同效果。
可选的，如图7和图8所示，弧形部20与平板部10可通过第一粘接层40固定连接。
其中，第一粘接层40的材料例如可以为光学透明胶(Optical Clear Resin，OCR)、双面胶等。
或者，可选的，弧形部20与平板部10通过机械方式固定连接。
其中，机械方式包括铆接、螺纹连接、卡扣连接等。
由于弧形部20与平板部10通过第一粘接层40或机械方式固定连接，因此可单独制作弧形部20，使得弧形部20的材料以及制作弧形部20的工艺可选择范围较广，而且可使弧形部20呈现不同的视觉效果。
在弧形部20与平板部10通过第一粘接层40或机械方式固定连接的基础上，对于弧形部20的具体结构，可有如下三种情况：
第一种情况：如图9a所示，弧形部20包括第一塑胶层21。
具体的，该弧形部20可采用普通的注塑工艺注塑成型。或者，可采用普通的注塑工艺制成3D后盖，采用计算机数字控制机床(Computer Number Control，CNC)精密加工去掉平面部分，留下的则为弧形部20。需要说明的是，去掉的平面部分应与本申请的平板部10尺寸一致，以保证留下的弧形部20与平板部10组合在一起，整体呈现3D效果。当采用后者形成弧形部20时，可使弧形部20与平板部10组合时的精度更高。
其中，可采取透明原料染色方式调节第一塑胶层21的透明度，当调节第一塑胶层21的透明度后，弧形部20的透过率会提高，从而使得其光泽质感反射更强。
由于作为第一塑胶层21的材料容易加工，可保证形状、厚度难以控制的弧形部20具有较高的加工精度，而且可使弧形部20的壁厚不均，使其内表面具有多样化的结构特征，从而可以满足不同产品的需求。
在此基础上，如图9b所示，由于平板部10还可以包括设置于玻璃板15内侧的第一镀膜层50，因此，当弧形部20采用普通的注塑工艺注塑成型，弧形部20也可包括第二镀膜层60，该第二镀膜层60可设置于第一塑胶层21的内侧，第一镀膜层50和第二镀膜层60的材料相 同。
其中，第一镀膜层50和第二镀膜层60的材料可选自于硅钛、铌、锡、铟、三氧化二铝等。
需要说明的是，图9b中以在玻璃板15内侧表面设置第一镀膜层50为例进行示意，但本申请并不限于此，在实际制作过程中，在玻璃板15和第一镀膜层50之间还可根据需要设置其他膜层。同理，第二镀膜层60也并不限于与第一塑胶层21接触。
对于后盖的平板部10而言，通常需要通过镀膜来赋予后盖相应的效果，因此，视玻璃板15所选择不同镀膜系，使设置于弧形部20的第二镀膜层60的材料与设置于平板部10的第一镀膜层50材料相同，可使弧形部20具有类似玻璃质感效果，从而使弧形部20视觉上具有与平板部10相同的质感，使得本申请的后盖整体形成仿3D玻璃效果。
第二种情况：如图10a所示，弧形部20包括由外至内依次层叠设置的IML膜片22、第二粘接层231、第二塑胶层24。
其中，如图10a所示，IML膜片22包括透明薄膜层221和印刷层222，印刷层222位于透明薄膜层221和第二粘接层231之间。在此基础上，IML膜片22还可包括设置在印刷层222和透明薄膜层221之间的纹理层，以使弧形部20外观面可具有炫光纹理等效果。
具体的，可将采用模内镶件注塑(In Molding Label，IML)工艺制成的后盖，采用CNC精密加工去掉平面部分，留下的则为弧形部20。需要说明的是，去掉的平面部分应与本申请的平板部10尺寸一致，以保证留下的弧形部20与平板部10组合在一起，整体呈现3D效果。
一方面，相对后盖整体由IML工艺制成，存在表面硬度不高，无法满足用户使用需求的问题，本申请由于平板部10采用玻璃板15，因此，可大大提高后盖整体表面的硬度；另一方面，相对后盖整体由IML工艺制成，存在印刷层无法覆盖边缘，从而使得后盖的弧形部20的厚度边缘露白，本申请由于在形成弧形部20时，可通过CNC将由IML工艺制成的后盖去掉平面部分得到，此过程同步将边缘的露白通过CNC去掉，因此，可避免该问题；再一方面，由于弧形部20还包括第二塑胶层24，可使弧形部20的壁厚不均，使其内表面具有多样化的结构特征。
在此基础上，如图10b所示，由于平板部10还可以包括设置于玻璃板15内侧的第一镀膜层50，因此，当弧形部20包括IML膜片22和第二塑胶层24时，弧形部20还可包括第二镀膜层60，该第二镀膜层60可设置于透明薄膜层221和印刷层222之间(当IML膜片22还包括纹理层时，第二镀膜层60设置于纹理层和印刷层222之间)，第一镀膜层50和第二镀膜层60的材料相同。基于此，可使弧形部20具有类似玻璃质感效果，从而使弧形部20视觉上具有与平板部10相同的质感，使得本申请的后盖整体形成仿3D玻璃效果。
第三种情况：如图11a所示，弧形部20包括由外至内依次层叠设置的表面硬化层25、PMMA和PC复合层26、油墨层27。其中，油墨层27起反衬颜色、遮光等效果。
具体的，可将采用复合板材后盖的加工工艺制成的后盖，采用CNC精密加工去掉平面部分，留下的则为弧形部20。需要说明的是，去掉的平面部分应与本申请的平板部10尺寸一致，以保证留下的弧形部20与平板部10组合在一起，整体呈现3D效果。
由于PMMA和PC复合层26本身材料强度较强，再加上表面硬化层25，可使表面性能高于上述第一种和第二种情况；而且，由于PMMA和PC复合层26本身材质透过率较好，因此， 可具有高透过率。
进一步可选的，如图11b所示，弧形部20还可以包括设置于油墨层27与PMMA和PC复合层26之间的纹理层28。
基于此，复合板材后盖的加工工艺可以包括：纹理制作、高压成型、表面处理、3D切边等工艺。
在弧形部20包括纹理层28的情况下，可使弧形部20具有炫光纹理等效果。
需要说明的是，根据需要还可在PMMA和PC复合层26与纹理层28之间设置标识(logo)层。
可选的，如图11c所示，弧形部20还可以包括依次设置于油墨层27远离PMMA和PC复合层26一侧的第三粘接层232和第三塑胶层29。
具体的，可将采用复合板材后盖的加工工艺制成的后盖作为嵌件，在油墨层27一侧形成第三粘接层232，之后采用IML工艺中形成塑胶层的工艺，注塑形成第三塑胶层29。在此基础上，采用CNC精密加工去掉平面部分，留下的则为弧形部20。
需要说明的是，采用CNC精密加工还可实现特殊特征，例如在平板部10存在左右边不对称、长边或短边非直线设计时，采用CNC精密加工后都可使弧形部20能与平板部10实现较好的配合。
其中，由于采用IML工艺中形成塑胶层的工艺来形成第三塑胶层29，因而使得第三塑胶层29可通过第三粘接层232与其他部分固定，因而可保证第三塑胶层29与其他部分的粘结力。
一方面，由于第三塑胶层29的存在，可实现弧形部20壁厚不均，内部结构特征多样化的特征，以适应不同架构的产品的需求；另一方面，可具有高质感、高韧性、高硬度(表面硬度可达4H)的特点。
在上述第三种情况下，如图11d和图11e所示，由于平板部10还可以包括设置于玻璃板15内侧的第一镀膜层50，因此，当弧形部20包括表面硬化层25、PMMA和PC复合层26、纹理层28以及油墨层27时，弧形部20还可包括第二镀膜层60，该第二镀膜层60可设置于油墨层27与纹理层28之间，第一镀膜层50和第二镀膜层60的材料相同。基于此，可使弧形部20具有类似玻璃质感效果，从而使弧形部20视觉上具有与平板部10相同的质感，使得本申请的后盖整体形成仿3D玻璃效果。
在此基础上，通过第一镀膜层50和第二镀膜层60还可实现渐变的效果，可满足多样化颜色-材料及最终表面处理(Color-Material-Finishing，CMF)的需求。当然，对于弧形部20，也可通过对PMMA和PC复合层26染色实现渐变，此时第二镀膜层60起增反膜作用，不带色。
基于上述的描述，需要说明的是，除上述提到的第一镀膜层50外，根据实际需求，在后盖的平板部10还可设置其他膜层，例如防指纹膜、硬化层等。
此外，图9a-图9b、图10a-图10b、图11a-图11e仅示意出图3中沿BB′向的剖面，对于沿CC′向剖面具有与沿BB′向的剖面相同的结构。
本申请还提供一种电子设备，包括上述的后盖。此外，还可包括中框、前盖等。中框可以由金属、合金、高分子材料以及各种复合材料制备而成。
本申请的电子设备具有与前述后盖相同的技术效果，在此不再赘述。
可选的，电子设备可以为手机、平板电脑等。
其中，电子设备中采用的显示面板可以是液晶显示面板，也可以是有机电致发光二极管(Organic Light-Emitting Diode,OLED)显示面板。
本申请还提供一种壳体，如图12所示，包括弧形部；该壳体70包括由外至内依次层叠设置的表面硬化层25、PMMA和PC复合层26、油墨层27、第三粘接层232和第三塑胶层29。
具体的，可将采用复合板材后盖的加工工艺制成的后盖作为嵌件，在油墨层27一侧形成第三粘接层232，之后采用IML工艺中形成塑胶层的工艺，注塑形成第三塑胶层29。
一方面，由于第三塑胶层29的存在，可实现壳体70壁厚不均，内部结构特征多样化的特征，以适应不同架构的产品的需求；另一方面，由于PMMA和PC复合层26本身材料强度较强，再加上表面硬化层25，可具有高质感、高韧性、高硬度(表面硬度可达4H)的特点；而且，由于PMMA和PC复合层26本身材质透过率较好，因此，可具有高透过率；再一方面，相对3D玻璃，本申请在能形成3D效果的基础上，还具有低成本的优势。
可选的，如图13所示，壳体70还包括设置于油墨层27与PMMA和PC复合层26之间的纹理层28。
在壳体70包括纹理层28的情况下，可使壳体70具有炫光纹理等效果。
需要说明的是，根据需要还可在PMMA和PC复合层26与纹理层28之间设置logo层。
进一步可选的，如图14所示，壳体70还包括设置于油墨层27与纹理层28之间的第二镀膜层60。
基于此，可使壳体70具有类似玻璃质感效果，形成仿3D玻璃效果。
在此基础上，通过第二镀膜层60还可实现渐变的效果，可满足CMF的需求。当然，对于壳体70，也可通过对PMMA和PC复合层26染色实现渐变，此时第二镀膜层60起增反膜作用，不带色。
在上述基础上，壳体可以为前壳或后盖。其中，前壳设置于中框与前盖板之间。
本申请还提供一种电子设备，包括上述的壳体。
可选的，该电子设备可以为手机、平板电脑等。
其中，电子设备中采用的显示面板可以是液晶显示面板，也可以是OLED显示面板。
