Description

一种中框及终端设备
本申请要求在2018年3月2日提交中国专利局、申请号为201810175739.4、发明名称为“一种中框及终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及机械领域，更具体的说，涉及中框及终端设备。
背景技术
随着智能手机的发展，行业内越来越重视智能手机的外观质感。由于不锈钢的强度高，而且质感出众，所以不锈钢已经成为众多智能手机的中框的材料。
目前，在相关技术中，采用CNC(Computer Numerical Control，计算机数字控制机床)将不锈钢板材加工成一体成型式的中框，但是，生产这种一体成型式的中框耗时较长。
发明内容
本申请实施例提供一种中框及终端设备，以解决生产中框耗时较长的问题。本申请实施例是这样实现的：
第一方面，本申请实施例提供了一种中框，包括中板、至少一个中间件、至少一个焊接台以及外框；至少一个中间件固定连接在中板的边缘；至少一个焊接台固定连接在外框的内侧；外框上的至少一个焊接台与中板上的至少一个中间件焊接连接。
在第一方面中，由于中板、至少一个中间件、至少一个焊接台和外框的结构形态比较简单，均可单独生产，而且中板、至少一个中间件、至少一个焊接台和外框之间的连接方式比较简单，相对于生产出一体成型式的中框，本申请实施例提供的中框的加工工艺更加简单，所以生产中框的耗时较短；另外，由于至少一个焊接台固定连接在外框的内侧，而且至少一个中间件固定连接在中板的边缘，所以便于将至少一个焊接台与至少一个中间件焊接在一起，从而保证中框具有较高的强度，以使中框具有较好的支撑性能。
在一种可能的实现方式中，至少一个中间件的第一端固定连接在中板的边缘，至少一个中间件的第二端向远离中板的方向延伸；
至少一个焊接台的第一端固定连接在外框的内侧，至少一个焊接台的第二端向外框的内侧延伸；
外框上的至少一个焊接台的第二端与中板上的至少一个中间件的第二端焊接连接，外框与中板之间形成间隙。
其中，虽然中板会将热量通过至少一个焊接台的第二端与至少一个中间件的第二端传导至外框上，但是外框与中板属于局部连接，外框与中板之间还存在的一定的间隙，所以中板通过局部连接的方式向外框传导热量的速度相对较慢，所以外框与中板之间的间隙可以起到隔热的效果。
在一种可能的实现方式中，外框与中板之间形成的间隙内填充有塑胶。
其中，可以使中框在跌落时具有较好的缓冲性能。
在一种可能的实现方式中，至少一个中间件嵌铸连接在中板的边缘。
其中，在中板压铸过程中，在中板处于熔融的状态下嵌入至少一个中间件，以使至少一个中间件可以更好的固定在中板上。
在一种可能的实现方式中，至少一个中间件嵌入中板的部分的与中板大致平行的横截面上最长的距离为100毫米。
在一种可能的实现方式中，至少一个中间件嵌入中板的深度小于或等于10毫米。
在一种可能的实现方式中，中板的表面上设置有至少一个凹槽，至少一个中间件上设置有卡扣，至少一个中间件的卡扣嵌入中板的至少一个凹槽内。
其中，在至少一个中间件的卡扣嵌入中板的至少一个凹槽内以后，至少一个中间件的卡扣会牢牢的勾住中板的至少一个凹槽，以使至少一个中间件与中板的连接性能更好。
在一种可能的实现方式中，固定连接包括嵌铸连接、粘接、铆接、锁螺丝连接以及凹槽卡扣连接中的至少一种。
在一种可能的实现方式中，至少一个中间件的材质为第一金属材料，至少一个焊接台的材质为第二金属材料，第一金属材料的熔点与第二金属材料的熔点之间的差值小于或等于熔点阈值，熔点阈值用于指示两种金属材料之间的可焊接性。
其中，熔点阈值用于指示两种金属材料之间的焊接性能。如果两种金属材料的熔点的差值小于或等于熔点阈值，那么说明两种金属材料的焊接性能良好；如果两种金属材料的熔点的差值大于熔点阈值，那么说明两种金属材料的焊接性能较差。因此，为了保证至少一个中间件与至少一个焊接台之间的焊接强度，需要选择两种焊接性能良好的金属材料。
在一种可能的实现方式中，至少一个中间件的材质为第一金属材料，至少一个焊接台的材质为第二金属材料，第一金属材料和第二金属材料的主元素相同，并且主元素在第一金属材料中的重量百分比含量以及主元素在第二金属材料中的重量百分比含量均大于或等于阈值，阈值的范围为60％至100％。
其中，阈值为主元素在金属材料中的重量百分比含量的分界值，用于衡量两种金属材料是否为同种材料。在至少一个中间件和至少一个焊接台为同种材料时，那么可以达到最佳的焊接效果。
在一种可能的实现方式中，第一金属材料和第二金属材料均为不锈钢、钛合金、铝合金、镁合金、锌合金或铜合金。
在一种可能的实现方式中，外框为利用轧制成型的不锈钢型材折弯且焊接得到的。
下面简要介绍如何得到外框：首先，可以轧制不锈钢板材以得到不锈钢型材；然后，将不锈钢型材折弯成带有缺口的长方形；最后，将带有缺口的长方形的不锈钢型材焊接成封闭的长方形的外框。
其中，由于外框是由不锈钢型材折弯且焊接得到的，所以加工外框的过程中不会浪费原材料。
第二方面，本申请实施例提供了一种终端设备，该终端设备包括显示屏和背壳，该终端设备还包括第一方面及第一方面的任意一种可能的实现方式中公开的中框，其中，显示器和背壳固定在该中框的两侧。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
请参见图1至图3所示，图1所示的为本申请实施例公开的一种中框的中板和至少一个中间件的示意图，图2所示的为本申请实施例公开的一种中框的至少一个焊接台和外框的示意图，图3所示的为本申请实施例公开的一种中框的整体示意图。
在图1至图3所示的实施例中，本申请实施例提供的中框10包括中板1、至少一个中间件2、至少一个焊接台3以及外框4，其中，至少一个中间件2固定连接在中板1的边缘，至少一个焊接台3固定连接在外框4的内侧，外框4上的至少一个焊接台3与中板1上的至少一个中间件2焊接连接。
在图1至图3所示的实施例中，由于中板1、至少一个中间件2、至少一个焊接台3和外框4的结构形态比较简单，均可单独生产，而且中板1、至少一个中间件2、至少一个焊接台3和外框4之间的连接方式比较简单，相对于生产出一体成型式的中框，本申请实施例提供的中框10的加工工艺更加简单，所以生产中框10的耗时较短；另外，由于至少一个焊接台3固定连接在外框5的内侧，而且至少一个中间件2固定连接在中板1的边缘，所以便于将至少一个焊接台3与至少一个中间件2焊接在一起，从而保证中框10具有较高的强度，以使中框10具有较好的支撑性能。
其中，固定连接的方式有很多种类，例如，固定连接可以包括嵌铸连接、粘接、铆接、锁螺丝连接以及凹槽卡扣连接中的至少一种。
其中，为了保证中框10具有较好的强度，至少一个中间件2、至少一个焊接台3以及外框4均可以采用不锈钢或钛合金等强度较高的金属制成，中板1可以采用铝合金或铜合金等金属制成。
在传统的制作外框的工艺中，需要在整块钢板上切割出原始形态的外框，整块钢板的其余部分将会被废弃，所以传统的制作外框的工艺会浪费大量的金属材料。
为了在加工外框4的时候节省原材料，本申请实施例的外框4可以为利用轧制成型的不锈钢型材折弯且焊接得到的。下面简要介绍如何得到外框4：首先，可以轧制不锈钢板材以得到不锈钢型材；然后，将不锈钢型材折弯成带有缺口的长方形；最后，将带有缺口的长方形的不锈钢型材焊接成封闭的长方形的外框4。
其中，由于外框4是由不锈钢型材折弯且焊接得到的，所以加工外框4的过程中不会浪费原材料。
在图1至图3所示的实施例中，为了保证至少一个中间件2与至少一个焊接台3之间的焊接强度，本申请实施例可以采用以下方式：
其中，至少一个中间件2的材质为第一金属材料，至少一个焊接台3的材质为第二金属材料，第一金属材料的熔点与第二金属材料的熔点之间的差值小于或等于熔点阈值。
其中，本申请实施例提到的第一金属材料和第二金属材料可以为很多种类。例如，第一金属材料和第二金属材料均为不锈钢；又如，第一金属材料和第二金属材料均为钛合金；再如，第一金属材料和第二金属材料均为铝合金；再如，第一金属材料和第二金属材料均为镁合金；再如，第一金属材料和第二金属材料均为锌合金；再如，第一金属材料和第二金属材料均为铜合金。当然，本申请实施例提到的第一金属材料和第二金属材料并不局限于上述已提到的金属材料。
另外，对于中板1和外框4的材质，可以选择的材料有很多种，本申请实施例并不限制中板1和外框4的材质。
在图1至图3所示的实施例中，熔点阈值用于指示两种金属材料之间的可焊接性。如果两种金属材料的熔点的差值小于或等于熔点阈值，那么说明两种金属材料的可焊接性良好；如果两种金属材料的熔点的差值大于熔点阈值，那么说明两种金属材料的可焊接性较差。因此，为了保证至少一个中间件2与至少一个焊接台3之间的焊接强度，需要选择两种可焊接性良好的金属材料。
在图1至图3所示的实施例中，为了保证至少一个中间件2与至少一个焊接台3之间的焊接强度，本申请实施例还可以采用以下方式：
其中，至少一个中间件2的材质为第一金属材料，至少一个焊接台3的材质为第二金属材料，第一金属材料和第二金属材料的主元素相同，并且主元素在第一金属材料中的重量百分比含量以及主元素在第二金属材料中的重量百分比含量均大于或等于阈值，其中，阈值的范围为60％至100％。
其中，阈值为主元素在金属材料中的重量百分比含量的分界值，用于衡量两种金属材料是否为同种材料。例如，假设将阈值设定为60％，那么如果第一金属材料中的主元素与第二金属材料中的主元素相同，而且第一金属材料中的主元素的重量百分比含量大于60％，第二金属材料中的主元素的重量百分比含量也大于60％，那么第一金属材料和第二金属材料属于同种材料。
其中，本申请实施例提到的第一金属材料和第二金属材料可以为很多种类。例如，第一金属材料和第二金属材料均为不锈钢；又如，第一金属材料和第二金属材料均为钛合金；再如，第一金属材料和第二金属材料均为铝合金；再如，第一金属材料和第二金属材料均为镁合金；再如，第一金属材料和第二金属材料均为锌合金；再如，第一金属材料和第二金属材料均为铜合金。当然，本申请实施例提到的第一金属材料和第二金属材料并不局限于上述已提到的金属材料。
另外，对于中板1和外框4的材质，可以选择的材料有很多种，本申请实施例并不限制中板1和外框4的材质。
在图1至图3所示的实施例中，在至少一个中间件2和至少一个焊接台3为同种材料时，那么可以达到最佳的焊接效果。
在图1至图3所示的实施例中，由于中板1分别与电池、芯片和电路板等发热量大的 部件相接触，所以中板1会将热量向外传导。如果中板1与外框4之间不存在间隙且完全贴合，那么中板1会将热量全部的传导至外框4上，以使用户的手接触温度较高的外框4时产生烫手的体验。
为了使中框10具有更好的隔热效果，本申请实施例可以采用以下方式保证外框4与中板1之间形成间隙：
其中，至少一个中间件2的第一端固定连接在中板1的边缘，至少一个中间件2的第二端向远离中板1的方向延伸；至少一个焊接台3的第一端固定连接在外框4的内侧，至少一个焊接台3的第二端向外框4的内侧延伸；外框4上的至少一个焊接台3的第二端与中板1上的至少一个中间件2的第二端焊接连接，外框4与中板1之间形成间隙。
在图1至图3所示的实施例中，虽然中板1会将热量通过至少一个焊接台3的第二端与至少一个中间件2的第二端传导至外框4上，但是外框4与中板1属于局部连接，外框4与中板1之间还存在的一定的间隙，所以中板1通过局部连接的方式向外框4传导热量的速度相对较慢，所以外框4与中板1之间的间隙可以起到隔热的效果。
在图3所示的实施例中，为了使中框10在跌落时具有较好的缓冲性能，本申请实施例可以采用以下方式：外框4与中板1之间形成的间隙内填充有塑胶5。
在图1至图3所示的实施例中，为了使至少一个中间件2更好的固定在中板1的边缘，本申请实施例可以采用以下方式：
其中，至少一个中间件2嵌铸连接在中板1的边缘。
在图1至图3所示的实施例中，在中板1压铸过程中，在中板1处于熔融的状态下嵌入至少一个中间件2，以使至少一个中间件2可以更好的固定在中板1上。
为了保证至少一个中间件2与中板1的连接关系更加稳固，可以在至少一个中间件2设置若干个孔，在中板1压铸过程中，处于熔融状态下液态金属可以流入至少一个中间件2上的若干个孔内。在中板1压铸完成以后，中板1与至少一个中间件2的连接关系会变得更加稳固。
另外，至少一个中间件2的形状可以有很多种类。例如，至少一个中间件2可以为长方体结构。当然，本申请实施例并不限制至少一个中间件2的具体形状。
请参见图4和图5所示，图4所示的为图1中A处放大的示意图，图5所示的为图1中A处放大的截面图。
在图4所示的实施例中，至少一个中间件2嵌入中板1的深度可以小于或等于10毫米。例如，在图4中，中间件2嵌入中板1的部分为带有中间件2中带有阴影的部分，中间件2嵌入中板1的深度为10毫米。
在图5所示的实施例中，至少一个中间件2嵌入中板1的部分的与中板1大致平行的横截面上最长的距离可以为100毫米。例如，在图5中，中间件2嵌入中板1的部分的与中板1大致平行的横截面上最长的距离可以为100毫米。
请参见图6所示，图6所示的为本申请实施例公开的另一种中框的中板和至少一个中 间件的示意图。在图6所示的实施例中，为了使至少一个中间件7更好的固定在中板6的边缘，本申请实施例可以采用以下方式：
在图6所示的实施例中，中板6的表面上设置有至少一个凹槽61，至少一个中间件7上设置有卡扣71，至少一个中间件7的卡扣71嵌入中板6的至少一个凹槽61内。
在图6所示的实施例中，在至少一个中间件7的卡扣71嵌入中板6的至少一个凹槽61内以后，至少一个中间件7的卡扣71会牢牢的勾住中板6的至少一个凹槽61，以使至少一个中间件7与中板6的连接性能更好。
请参见图7所示，图7所示的为本申请实施例公开的一种终端设备的示意图。图7所示的终端设备包括显示屏20、背壳30和图3所示的中框10，其中，显示器20和背壳30固定在该中框10的两侧。
