如图1所示，现今市面上中高档手机框架结构材质一般为铝合金，是由一整块铝合金加工而成。铝合金手机框架一体成型，按原材料分为压铸铝和铝板两种。
对于压铸铝框架结构，因为压铸件材料本身不致密，在做阳极氧化，抛光，喷砂等表面处理时不但良品率低，而且表面处理效果差不美观，比如，一般最后做喷漆处理，喷漆处理的框架容易掉漆，档次低，无法用于高端手机。
而对于铝板手机框架结构，整个框架结构需要通过机加工成型，其主要缺点为加工工作量大，加工时间长，造成效率低，同时，材料利用率低。
此外，手机壳如今越做越薄，并且尺寸越来越大，铝合金手机壳强度越来越无法满足需求，尺寸变大，厚度变薄后手机壳容易变弯，手机在不小心摔在地上后容易变形。
现有技术中，手机框架还有组合的形式，即设计一硬质外框与中间板配合的方式，但是由于外框与中间板连接不牢固，在CNC加工（如天线端槽、孔、边优化）过程中的相对晃动会造成加工误差，不利于产品的精密加工。

【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图11，本发明提供一种手机框架，该手机框架包括外框100、中间板200以及第一塑胶300。
其中，外框100通过钛合金条料经预定尺寸折弯后获得，中间板200设于外框100内，第一塑胶300将中间板200的外缘与外框100的内侧壁以注塑方式固定连接。
以下将结合附图描述该手机框架的制造过程。
首先，将图2中所示的钛合金条料外框100经预定尺寸折弯形成图3所示的形状，所述预定尺寸根据具体手机型号的需要确定。
在具体实施例中，外框100可由一条钛合金条料折弯成型，或者外框100由图3所示的两条钛合金条料折成，每一钛合金条料包括主体部101、延伸于主体部101一端的第一折条102、延伸于主体部101另一端的第二折条103。采用钛合金条料作外框100即节约材料，又大大地增加了强度。
在本发明选实施例中，第一折条102和第二折条103的长度相异。如图3中所示，左边的钛合金条料的第一折条102相对第二折条103较短。当然，在其他实例中，第一折条102和第二折条103的长度也可以相同。
在将钛合金条料经预定尺寸折弯形成图3所示的形状后，再对外框100进行数控加工处理，如图4所示，为了便于和中间板200配合，外框100上还设有由CNC加工出的多个配合台110、配合孔120以及配合凹部130，配合台110用于承载中间板200，配合孔120和配合凹部130用于接收第一塑胶300填充。其中，配合台110包括横向配合台111和纵向配合台112，横向配合台111用于承托中间板200。纵向配合台112用于与中间板200的注塑孔210插置配合。此外，还可在钛合金条料上加工充电槽、侧健槽、音频插孔等必要结构，由于不涉及发明点所在，此处不进行详述。
请参阅图5，在本发明实施例中，中间板200优选为铝板，铝板具有轻质、易加工特点，经冲压后形成预定形状，如图6所示，中间板200经冲压形成多个注塑孔210。多个注塑孔210可包括设于边缘的半孔和全孔。采用铝板200作为中间板20即节约加工时间，又节约材料。当然，本发明不对中间板20的材料作限定，中间板20也可以采用钛合金或其他材料。
请参阅图7和图8，钛合金条料的外框100和中间板200经过上述加工后可进行配合注塑，即利用第一塑胶300将中间板200的外缘与外框的内侧壁以注塑方式固定连接。
请参阅图9，在将加工后的钛合金条料的外框100与加工后的中间板200组合并填充第一塑胶300后，再在外框100上进一步设有由CNC加工的端槽140，端槽140用于允许无线信号通过，并再在第一塑胶300于端槽140处进一步开设注塑孔310。
请参阅图10，手机框架还包括第二塑胶400，第二塑胶400从第一塑胶300上的注塑孔310填入，其中，该第二塑胶400所采用的材料不同于第一塑胶300所采用的材料，第一塑胶300所采用的材料主要是起到固定连接作用，而第二塑胶400所采用的材料对于无线信号的传输有利。
请参阅图11，最后将不必要的塑胶进行去除整形，将注塑孔孔壁以及多余的塑胶填料去除，利用CNC加工出平滑过渡的外轮廓。
本发明可提高手机壳加工效率，同时，提升手机壳产品质量。
与传统的手机框架制造方法不同，本发明将手机框架为两部分加工，即外框100和中间板200，其中，外框100采用高硬度材料（如钛合金），中间板200采用铝材相关材料（也可以采用钛合金，主要是考虑到成本以及手机内部并不需要高硬度材料），加工工艺如上述所，从而，一方面由于本发明并不需要对整块铝板进行机加工，而是对钛合金型材100进行切割，对中间的中间板202进行冲压，这样节省了加工时间，提高了效率；同时，外框100采用高硬度材料，使得手机外壳更加结实，不易变形，也不容易被刮伤。
本发明既有加工量少，加工时间短等优点，又避免了压铸件材料不致密而使表面处理困难等缺点，且采用钛合金型材做外框，其本身具备耐腐蚀高强度等优点，无需做更多的表面处理，简化的手机框架的工艺。
此外，本发明还提供一种手机，该手机包括屏幕、电路板单元、电池模块等本领域技术人员公知的部件以及上述的手机框架，其中，电池模块向屏幕和电路板单元供电，手机框架支持屏幕、电路板单元、电池模块的安装。
请一并参阅图12，图12是本发明优选实施例的手机框架的制造方法的流程图。
本发明还提供一种手机框架的制造方法，包括以下步骤：
S110，将钛合金条料以预定尺寸折弯形成外框。在本步骤中，外框可由一条钛合金条料折成，或者外框由图6所示的两条钛合金条料折成。
S120，对所述外框进行加工处理以形成安装结构。
S130，对铝材中间板进行冲压处理。
S140，利用第一塑胶将所述中间板的外缘与所述外框的内侧壁以注塑方式固定连接。
S150，在所述外框上开设通过CNC加工端槽，并在所述端槽处的所述第一塑胶上开设注塑孔。
S160，利用第二塑胶从所述第一塑胶上的注塑孔填入。
最后，将不必要的塑胶进行去除和清理，并通过CNC加工出平滑过渡的外轮廓即可。
其中，第二塑胶所采用的材料不同于第一塑胶所采用的材料，第一塑胶所采用的材料主要是起到固定连接作用，而第二塑胶所采用的材料对于无线信号的传输有利。
综上所述，本领域技术人员容易理解，本发明提供的手机框架由于采用了钛合金外框和铝材中间板并利用注塑方式固定，使得手机框架结构简单、加工工作量相对较少、加工时间相对较短、效率高、良率高、材料利用率高，制造方便，强度可靠、外观精美。因钛合金硬度远远大于铝合金的硬度，用钛合金做的手机框架更难被刮伤，本发明通过注塑的方式进行固定后再进行CNC加工，再进行二次注塑，保证了加工的一致性和准确性。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
