Description
【技术领域】
本发明涉及移动通信设备制造技术领域，具体涉及一种手机、手机框架及其制造方法。
【背景技术】
请参阅图1，图1是现有技术中一种手机框架的结构示意图。
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。
【发明内容】
本发明提供一种手机、手机框架及其制造方法，以解决现有技术中手机框架存在良率低、不美观、加工工作量大、手机框架硬度不够的问题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种手机框架，所述手机框架包括：
外框，通过钛合金条料经预定尺寸折弯后获得；
中间板，设于所述外框内，且所述中间板的外缘连接于所述外框的内侧壁。
根据本发明一优选实施例，所述外框由一条钛合金条料折弯成型。
根据本发明一优选实施例，所述外框由两条钛合金条料折成，每一钛合金条料包括主体部、延伸于所述主体部一端的第一折条、延伸于所述主体部另一端的第二折条。
根据本发明一优选实施例，所述第一折条和所述第二折条的长度相异或相同。
根据本发明一优选实施例，所述外框上加工有充电槽、侧健槽、音频插孔。
根据本发明一优选实施例，所述外框上加工有固定台，用于设置所述中间板。
根据本发明一优选实施例，所述中间板为铝材或钛合金，经冲压后形成预定形状。
根据本发明一优选实施例，所述外框与所述中间板焊接连接或卡合连接。
根据本发明一优选实施例，所述外框上进一步开设有端槽，以允许无线信号通过。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种手机，所述手机包括屏幕、电路板单元、电池模块、以及上述的手机框架，所述电池模块向所述屏幕和所述电路板单元供电，所述手机框架支持所述屏幕、所述电路板单元、所述电池模块的安装。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种手机框架的制造方法，包括以下步骤：
将钛合金条料以预定尺寸折弯形成外框；
对所述外框进行加工处理以形成充电槽、侧健槽、音频插孔、固定台；
对铝材中间板进行冲压处理；
将所述中间板通过焊接或卡合连接方式设置于所述外框内并在所述外框上开设端槽。
本发明的有益效果是：区别于现有技术的情况，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，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。
【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图，其中：

【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。
本发明提供一种手机框架，请一并参阅图2至图4，本发明提供的手机框架包括外框10和中间板20，其中，外框10通过钛合金条料经预定尺寸折弯后获得，中间板20可通过焊接连接、卡合连接等固定方式设于外框10内。
以下将结合附图描述该手机框架的制造过程。
首先，将图5中所示的钛合金条料100经预定尺寸折弯形成图6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10可由一条钛合金条料100折弯成型，或者外框10由图6所示的两条钛合金条料100折成，每一钛合金条料100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100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6中所示，左边的钛合金条料100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100经预定尺寸折弯形成图6所示的形状后，再对外框10进行数控加工处理，例如，在钛合金条料100上加工充电槽110、侧健槽120、音频插孔130等必要结构。此外，为了便于和中间板20配合，外框10上还加工有固定台140，以便于承托设置中间板20。
请参阅图8，在本发明实施例中，中间板20优选为铝板200，铝板200具有轻质、易加工特点，经冲压后形成预定形状，如图9所示，经冲压形成通孔210、装配槽220等。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10，钛合金条料100和铝板200经过上述加工后可通过焊接连接或卡合连接组合。
请参阅图11，将加工后的钛合金条料100与加工后的铝板200组合后，再在外框10上进一步开设端槽140，以允许无线信号通过。
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10和中间板20，其中，外框10采用高硬度材料（如钛合金），中间板20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10进行切割，对中间的中间板20进行压铸，这样节省了加工时间，提高了效率；同时，外框10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。
本发明既有压铸件加工量少，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，所述电池模块向所述屏幕和所述电路板单元供电，所述手机框架支持所述屏幕、所述电路板单元、所述电池模块的安装。
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100折成。
S120，对所述外框进行加工处理以形成充电槽、侧健槽、音频插孔、固定台。
S130，对铝材中间板进行冲压处理。
S140，将所述中间板通过焊接或卡合连接方式设置于所述外框内并在所述外框上开设端槽。其中，所述端槽用于允许无线信号通过。
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10和铝材中间板20，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。
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。
