具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
需要说明的是，在本申请的各个方面中所描述的特征和效果可以互相适用，在此不再赘述。
在本申请的一个方面，本申请提出了一种在本申请的第一方面，本申请提出了一种电池盖板。具体的，参考图1，该电池盖板包括：基体100、侧边框部200以及固定部300。根据本申请的实施例，侧边框部200垂直设置在基体100的边缘上。根据本申请的实施例， 固定部300平行于基体100，且设置在侧边框部200远离基体100的一侧。由此，可以利用固定部300固定连接在电池盖板上的其他零件，例如固定用于连接天线件以及主板的金属弹片，从而可以实现稳定的固接。该电池盖板具有以下优点的至少之一：结构简单，制备成本低廉，可通过垂直向的螺钉固定金属弹片，从而避免使用对工艺要求较高的水平向固定螺钉。
需要特别说明的是，在本申请中，垂直向特指垂直于基体100的主面的方向，水平向特指和基体100主面方向平行的方向。
本申请是发明人基于以下发现而做出的：目前的金属电池盖板，普遍存在跌落后，易出现天线性能下降甚至失效等问题。发明人经过深入研究以及大量实验发现，这主要是由于，为了实现通信功能，目前的电池盖板上普遍设置有天线。天线通过金属弹片等结构，与手机等移动终端的主板相连。然而由于弹片以及金属盖板之间难以实现可靠的固接，因此容易在移动终端跌落后，出现不稳定连接，导致接触阻抗变化，甚至断开的情况，从而引起天线漂移、衰弱或失效。
根据本申请的一些示例，基体100、侧边框部200以及固定部300是由金属形成的。由金属形成基体100、侧边框部200以及固定部300，不仅可以为手机提供具有金属质感的外观，且相较于塑料材质的电池盖板，具有更加优秀的散热功能，以及抗磨损性能。形成基体100、侧边框部200以及固定部300的具体金属类型不受特别限制，本领域技术人员可以根据实际需求进行选择。例如，可以为铝合金。
根据本申请的一些示例，基体100的表面包括平面以及弧面的至少之一。也即是说，该电池盖板可以为平面电池盖板，也可以为表面具有一定弧度的盖板，即3D电池盖板。或者，基体100的表面的一部分区域可以为平面，另一部分区域可以为弧面：如基体100的中央位置可以为平面，周边区域可以为向下弯曲的弧面。
如前所述，金属材料形成的电池盖板，需要在电池盖板上设置天线，并将其与主板进行连接，以实现天线辐射信号的功能。而连接天线以及主板的金属弹片，由于固定的稳定性不佳，常造成天线在手机等设备跌落之后，发生信号衰减，甚至天线失效的问题。虽然这一问题可以通过利用螺钉等固定件，将金属弹片固定在电池盖板上得到解决。然而，鉴于移动终端普遍要求电池盖板的厚度要较薄，因此电池盖板如需设置螺钉等固定件，普遍采用的是沿平行于电池盖板主体的方向进行打孔，设置螺钉进行金属弹片的固定。沿平行于电池盖板主体(即手机屏幕平面)方向进行打孔，在工艺上难度较大。因此，该设计虽然可以实现金属弹片的稳定固接，然而加工费时耗力，严重影响电池盖板的生产效率，且生产成本也随之大幅提升。
根据本申请实施例的电池盖板，具有平行于基体100的固定部300。由此，可以简便地 利用固定部300，沿着垂直于基体100的方向，进行打孔、设置螺钉，从而实现金属弹片的固接。本领域技术人员能够理解的是，固定部300不仅可以用于固定金属弹片，还可以用于固定其他零件，如固定需要与电池盖板形成稳定固接的部件。由此，可以避免对工艺要求较高的、沿水平方向(平行于基体100所在的平面)设置螺钉的操作，从而可以在保证该电池盖板的生产效率、节约生产成本的前提下，提高利用该电池盖板的移动终端的使用性能。
具体的，参考图2，该电池盖板还可以包括多个侧边框部200。根据本申请的实施例，多个侧边框部200围绕基体100设置。也即是说，多个侧边框部200均垂直设置在基体100的边缘上。由此，多个侧边框部200可以充当手机等移动终端的部分侧边框，与基体100可以为一个一体化的整体盖板。根据本申请的实施例，侧边框部200的具体数量不受特别限制，本领域技术人员可以根据实际需求进行选择。例如，根据本申请的实施例，多个侧边框部200可以是由侧边框部200A以及侧边框部200B组成的。更具体地，侧边框部200A以及侧边框部200B可以相对于基体100对称设置。
根据本申请的实施例，参考图3，形成该基体100的板材的具体形状不受特别限制，例如，可以由拐角为圆角的四边形板材形成基体100。由此，可以进一步提高由该基体100形成的电池盖板的外观效果。根据本申请的一些示例，基体100的4个边缘中的每一个上，均可以设置有侧边框部200。根据本申请的示例，相邻的侧边框部200彼此相连。也即是说，彼此相连的4个侧边框部200，与基体100构成碗状结构。根据本申请的实施例，该电池盖板可以具有多个固定部300(如图3中的300A，300B)。根据本申请的实施例，固定部300的具体数量不受特别限制，本领域技术人员可以根据实际需求进行选择。多个固定部300设置的位置也不受特别限制，本领域技术人员可以根据需要进行固定的零件(如金属弹片)的位置，进行设置。例如，根据本申请的实施例，固定部300可以设置在与基体100(或侧边框部200)的拐角相对应的位置处(如固定部300B)，或设置在侧边框部200的中部(如固定部300A)。
根据本申请的实施例，基体100、侧边框部200以及固定部300一体成型。由此，可以利用一块金属板材，形成基体100、侧边框部200以及固定部300，从而一方面可以节省组装上述部件的时间，另一方面，可以避免基体100、侧边框部200以及固定部300由不同材料形成时，在连接处发生诸如腐蚀、连接失效等问题，进而可以延长该电池盖板的使用寿命。
根据本申请的实施例，参考图4，固定部300上设置有用于设置固定件320的贯穿孔(图中未示出)，以便固定件320能够沿垂直于基体100的方向固定在固定部300上。根据本申请的实施例，固定在固定部300上的固定件320的具体类型不受特别限制。例如，根据本 申请的具体实施例，可以是利用螺钉321将金属弹片322垂直固定在固定部300上，其中，金属弹片322可以用于连接主板与天线件。由此，可以通过垂直向的螺钉321固定金属弹片322，从而避免使用对工艺要求较高的水平向固定螺钉。并且利用固定部300固定金属弹片322，可以实现稳定的固接。
总的来说，该电池盖板具有以下优点的至少之一：结构简单，制备成本低廉，可通过垂直向的螺钉固定金属弹片，从而避免使用对工艺要求较高的水平向固定螺钉。
在本申请的另一方面，参考图5，本申请提出了一种制备前面所述的电池盖板的方法。根据本申请的实施例，该方法包括：
S100：形成预制料
根据本申请的实施例，在该步骤中，将板材进行切割处理，以便形成预制料。根据本申请的实施例，预制料可以包括用于形成基体的本体，以及用于形成侧边框部和固定部的边缘。根据本申请的实施例，板材为金属板材。根据本申请本实施例，切割处理的具体方式不受特别限制，只需满足切割处理的要求即可。例如，根据本申请的实施例，切割处理可以为数控机床切割(CNC)处理。由此，可以进一步提高利用该方法制备得到的电池盖板的使用性能。
根据本申请的具体实施例，板材切割处理后形成的预制料的具体形状不受特别限制，例如，预制料可以为图6中的(a)所示的形状，其中，预制料的边缘可以是用于形成侧边框部和固定部的边缘。
S200：冲压处理
根据本申请的实施例，在该步骤中，对预制料进行冲压处理，以便利用边缘，形成垂直于本体的侧边框部。根据本申请的实施例，冲压处理的具体设备不受特别限制，只需满足冲压处理的要求即可。例如，可以根据上述预制料的尺寸、形状、精度来进行选择。
根据本申请的具体实施例，对预制料进行冲压处理所形成的结构可以为图6中的(b)所示，即侧边框部200垂直设置在基体100的边缘上，并且侧边框部200围绕基体100设置。需要说明的是，所形成的侧边框部200中，具有预留的部分，以便在后续工艺过程中形成固定部300。
S300：翻边挤压处理
根据本申请的实施例，在该步骤中，对边缘中，用于形成固定部的部分进行翻边挤压处理，以便形成平行于基体的固定部。根据本申请本实施例，翻边挤压处理的具体方式不受特别限制，只需满足翻边挤压处理的要求即可。由此，可以简便地获得前面描述的电池盖板。该方法具有可以节省原料成本、降低成本、缩短工艺制程等优点的至少之一。
根据本申请的具体实施例，进行翻边挤压处理所形成的结构如图6中的(c)所示，基 体100、侧边框部200以及固定部300一体成型，基体100的4个边缘中的每一个上，均设置有侧边框部200。根据本申请的实施例，相邻的侧边框部200彼此相连，多个固定部300分别设置在与拐角相对应的位置处，以及侧边框部200的中部。
发明人发现，通过在预制料中预留用于形成固定部300的材料，并通过翻边挤压处理形成固定部300，不仅可以简便地获得前面描述的平行于基体100的固定部300，且与直接采用数控机床切割(CNC)形成前面描述的电池盖相比，根据本申请实施例的方法具有更加节省金属板材的优点：如利用CNC技术，切割出于侧边框部200连接的固定部300，则需要对一块较厚的板材(厚度约为基体100的厚度以及侧边框部200的高度之和)进行挖空处理。一方面造成大面积CNC切割，耽误工时，另一方面，挖空部分的金属板材被浪费，从而间接造成了生产成本的提高。而如采用翻边挤压处理，则一方面可以避免大面积CNC处理，节省工时，另一方面，利用上述方法制备电池盖板时，所采用的板材的厚度，仅需与基体100的厚度相等即可。由此，可以进一步节约生产成本。
根据本申请的实施例，为了进一步提高利用该方法制备的电池盖板的性能，该方法进一步包括：
S400：设置固定件
根据本申请的实施例，在该步骤中，在固定部设置贯穿固定部且垂直于基体的固定件。由此，可以利用垂直于基体的诸如螺钉的固定件固定弹片以及电池盖板，避免使用对工艺要求较高的水平向固定件。
根据本申请的具体实施例，参考图7中的(d)，固定部300上设置有用于设置固定件320的贯穿孔，以便固定件320能够沿垂直于基体100的方向固定在固定部300上。根据本申请的实施例，固定部300的形成贯穿孔的具体方式不受特别限制，只需满足形成贯穿孔的要求即可。例如，根据本申请的具体实施例，可以是通过钻孔形成的。根据本申请的具体实施例，通过翻边挤压处理形成的固定部300平行于基体100，由此可以对该固定部300垂直于基体100的方向进行打孔处理形成用于设置固定件320的贯穿孔，在后续工艺过程中，可以通过垂直向的螺钉固定金属弹片，从而避免使用对工艺要求较高的水平向固定螺钉。
根据本申请的实施例，在完成设置固定件的步骤后，该方法可以进一步包括以下步骤：
参考图7，首先，可以是利用螺钉321将金属弹片322垂直固定在固定部300上，实现稳定固接，金属弹片322和基体之间不会相互移动。根据本申请的实施例，该方法还可以进一步包括对基体100进行钻孔攻牙等工艺过程，得到诸如摄像头孔400、耳机孔500、充电孔600等结构。最后，再把主板700装配到基体100中，并且主板700与金属弹片322稳定固接，整个连接回路实现稳定连接。由此，可以通过垂直向的螺钉321固定金属弹片 322，从而避免使用对工艺要求较高的水平向固定螺钉。并且可以利用固定部300固定用于连接天线件以及主板的金属弹片322，从而可以实现稳定的固接。根据本申请的具体实施例，在电池盖板上装配主板700后的结构如图7中的(f)所示。
在本申请的又一方面，本申请提出了一种壳体组件。根据本申请的实施例，参考图4，该壳体组件包括：前面所述的电池盖板100以及金属弹片322。根据本申请的实施例，金属弹片322通过螺钉321，固接在电池盖板的固定部300上，螺钉321贯穿固定部300且垂直于电池盖板的基体100设置。由此，可以使得金属弹片322以及电池盖板之间形成稳定的固接，从而缓解利用该壳体组件的移动终端，由于跌落而导致天线性能下降或失效的问题。
在本申请的又一方面，参考图8，本申请提出了一种移动终端1100。根据本申请的实施例，该移动终端1100包括前面描述的壳体组件1000。由此，可以具有前面所述的壳体组件1000所具有的全部特征以及优点，在此不再赘述。总的来说，该移动终端1100可以缓解由于跌落而导致天线性能下降或失效的问题。需要特别说明的是，由于前面描述的壳体组件1000中，固定件设置在壳体组件的内侧，因此，该移动终端1100的外表面，并无可见的固定螺钉。由此，可以进一步提高该移动终端1100外观的整体一致性。
下面通过具体实施例对本申请进行说明，需要说明的是，下面的具体实施例仅仅是用于说明的目的，而不以任何方式限制本申请的范围，另外，如无特殊说明，未具体记载条件或者步骤的方法均为常规方法，所采用的试剂和材料均可从商业途径获得。
