具体实施方式
下面结合附图和实施例对本发明做进一步说明。
请参照图1至图4，本无基材手机软壳10包括底部11和环绕在所述底部11的周边的侧部12，所述侧部12为第二面层121和第二里层122胶合构成的双层结构，进一步在底部11的内侧胶合有里层，这样底部11也为双层结构，即底部11由第一面层111和第一里层112构成，所述侧部12的双层结构之间于所述软壳的口部处夹设有刚性细丝，所述刚性细丝的首尾相接构成支撑及保持口部形状的环形骨架14。
请参照图3，上述无基材手机软壳10由两块布料制成，一块布料成型了第 一面层111、第二面层121和第二里层122，另一块布料成型了第一里层112。
本申请中，软壳10的底部11也可采用单层结构。这种实施方式中，所述底部11和所述侧部12由同一片材制成。
上述构成所述底部11和所述侧部12的片材为布料。但本申请也可以采用皮料或其它类似的材料。
进一步所述刚性细丝为覆有胶套的钢丝。胶套一方面起防止钢丝生锈的作用，另一方面使得环形骨架14可以产生微小的收缩，更利于将手机嵌入该软壳中。
请参照图5，本无基材手机软壳10进一步在底部11开设有摄像头孔13，且在摄像头孔13的边沿卡设有包边15。包边15一方面起装饰作用，另一方面起防止脱线的作用。包边15优选金属片。
请参照图6，上述无基材手机软壳10的一种成型工艺包括以下步骤：
步骤S1、开料。采用冲切、激光切割等方式裁切布料，得到面料和里料，面料的尺寸要大于壳体的底部11尺寸与两倍侧部12尺寸之和，里料尺寸与壳体底部11尺寸相同或略小。
步骤S2、面料覆胶。在面料的背侧融合热熔胶片。具体地，将裁切好的面料放入定位模具，在所述定位模具的胶片腔中依次放入热熔胶片和PC薄片，然后将覆有热熔胶片和PC薄片的所述面料加热使所述热熔胶片融化。这里的PC薄片作为工艺片使用，用于防止布料经过高温的时候粘在一起，在成型后会取出该PC薄片。
步骤S3、拉伸成型。图7中示出了拉伸模具20的结构，其包括外模21和内模22，外模21中部具有型腔211。具体的拉伸成型方法包括：将所述面料放至拉伸模具20的外模21上，向下推压置于所述面料上方的拉伸模具20的内模22进入外模21中部的型腔211，从而使所述面料的中部向下运动将所述面料拉伸成具有底部11和侧部12的第一半成品，冷却定型，去除拉伸模具20后获得 所述第一半成品。
步骤S4、嵌装环形骨架14。环型骨架如图4所示，其与本无基材手机软壳10的口部的形状及尺寸相匹配，用于支撑及保持本无基材手机软壳10的口部形状，具体可采用钢丝，在钢丝外套设有胶套，然后将钢丝首尾相接形成环状结构。
嵌装环形骨架14的步骤中用到两个模具，一个是芯模30，如图8所示，另一个是推边模具40，如图9所示。请参照图8，芯模30由左模部31和右模部32两部分对接组成，芯模30的上端具有下凹部33，用于定位环形骨架14。请参照图9，推边模具40包括上模部43和下模部41，下模部41能够容置在芯模30中并与芯模30的侧部配合将第一半成品的侧部夹紧，上模部43比下模部41略小，在上模部43和下模部41的连接部形成内凹部42、用于容置环形骨架14。
嵌装环形骨架14的具体方法包括：在所述第一半成品中嵌入芯模30，在所述芯模30的上端放置环形骨架14，然后用推边模具40推动所述第一半成品的边沿内折包裹所述环形骨架14后夹紧在所述芯模30和所述推边模具40之间，高温加热，然后将边沿整理平整，然后冷却定型，然后取出所述推边模具40和所述芯模30，获得口部定型且嵌有环形骨架14的第二半成品。
步骤S5、胶合。用所述推边模具40将所述第二半成品的边沿内折，高温加热将面料背侧的热熔胶片融化，挤压使折叠后的两层面料胶合，然后冷却定型，取出推边模具40，获得具有双层结构的侧部12的第三半成品。
步骤S6、冲切边沿。向所述第三半成品装入冲切模具，冲压将面料多余的部分去除。然后剥离所述PC薄片。
步骤S7、干燥。放入干燥机中烘干。
步骤S8、胶合里料。在里料的背侧压热熔胶片，然后将压有热熔胶片的里料放入步骤S7处理后的无基材软壳内，热压，使所述热熔胶片融化将所述里料 和面料胶合，构成双层结构的底部11。
步骤S9、开摄像头孔13，获得最终的无基材软壳。开孔优选激光切割的方式。
本实施例中的冷却在冰水中进行。
可以看出，最后获得的手机软壳中没有任何起支撑作用的刚性板材，也就是说，制得的是一种由布料构成的无基材手机软壳10。
可以理解地，通过上述工艺，采用皮料或其它类似的材料也可以制得无基材手机软壳10，并且采用上述工艺不但可以成型手机软壳，也可以成型任何由底部11和四个侧部12构成的软壳。
上述通过具体实施例对本发明进行了详细的说明，这些详细的说明仅仅限于帮助本领域技术人员理解本发明的内容，并不能理解为对本发明保护范围的限制。本领域技术人员在本发明构思下对上述方案进行的各种润饰、等效变换等均应包含在本发明的保护范围内。
