Description

电子设备的承重结构 发明领域
本发明涉及电子设备承重结构，具体涉及一种将负载通过固定板板转移到电子设备外壳，从而避免了电路板在负载的拉扯下变形损坏的承重结构。
背景技术
随着电子设备日益复杂，相关非电子组件也在不断发展。以电脑为例，散热结构比重越来越高，超过1000克的散热器越来越多。因为显卡过重而损坏主板插槽亦有不少，主板大厂纷纷推出各种加强显卡插槽和带护甲的高端主板。然而CPU的散热结构对主板可能造成的损坏，却被忽视了。
常见的大型塔式散热器，包含主负载、支架、固定板。其中主负载和支架，与固定板位于主板平面的两侧。主负载通过支架将负载分散到固定板，支架通过主板穿孔连接固定板。这个设计在主板水平放置的情况下没问题，但在主板竖直放置和在移动环境反复加减速的情况下，会对主板造成损坏。相较于CPU、内存，主板本来也易于因为灰尘、潮湿、辐射而损坏，大部分用户不会留意具体损坏原因。但问题在于电脑的所有组件都通过主板而相互连接，维修或更换主板意味着彻底的拆卸和安装以下所有组件：CPU、散热器(风扇)、内存、硬盘、显卡(和其它扩展卡)、电源、机箱、开关/重启/硬盘灯/前置音频/USB连接线、后置音频/USB/网线/DisplayPort/HDMI……无疑是个颇为消耗人力的过程，更别提保修流程里15～30天的等待检测，用户只能通过备用电脑维持学习和/或工作。
显然，作为最薄弱的中心环节，增强主板的耐用性，将极大提高整个系统的可用性，降低维护成本。
发明概述
现有技术的问题在于，负载转移到固定板，而整体的承重却通过电路板的安装孔(mounting holes)转移到电子设备的外壳。本发明提供了一种电子设备承重结构，包含电路板、负载物、支架、固定板，其特征在于，所述固定板固定于电子设备的外壳中，从而避免了所述电路板受所述固定板的拉扯变形损坏。
然而，应当理解，本发明内容可能不包含本发明的所有方面和实施例，该发明内容并不意味着以任何方式进行限制或限制，并且本文公开的本发明将被下列之一理解：本领域普通技术人员包括对其的明显改进和修改。
附图说明
图1-3是现有技术的一个示范性实施例的分解图，展示了现有技术中，电路板、负载物、支架、固定板如何组装起来。
图4、5是现有技术的一个示范性实施例的透视图，分别展示了电路板在水平和竖直位置，主负载如何通过电路板的安装孔(mounting holes)转移到电子设备的外壳。
图6-8是本发明的一个示范性实施例的分解图，展示了固定板如何被固定于电子设备的外壳。
图9是本发明的另一个示范性实施例的分解图，展示了固定板，如何与电路板，通过与电路板位置相对应的安装孔，一起被固定于电子设备的外壳。
根据一般惯例，各种所描述的特征没有按比例绘制并且被绘制以强调与本公开相关的特征。在所有附图中，相同附图标记表示相同的元件。
具体实施方式
现在将在下文中参照附图更充分地描述本发明，附图中展示了本发明的示范性实施例。然而，本发明可以以许多不同的形式实施，并且不应被解释为限于本文所阐述的实施例。但愿，提供这些实施例使得本公开将是彻底和完整的，并且将向本领域技术人员充分地传达本发明的范围。相同的附图标记始终表示相同的元件。
应当理解，在不脱离所附权利要求中阐述的精神和范围的情况下，可以对元件的功能和布置进行各种改变。因此，实施例是本发明的示例或实现，而不是唯一的实现。各种出现“一个实施例”，“实施例”或“一些实施例”不一定都指代相同的实施例。虽然可以在单个实施例的上下文中描述本发明的各种特征，但是特征也可以单独地或以任何合适的组合提供。相反的，尽管为了清楚起见，本文中可以在单独的实施例的上下文中描述本发明，但是本发明也可以在单个实施例或实施例的任何组合中实现。
除非另有定义，本文使用的所有术语(包括技术和科学术语)具有与本发明所属领域的普通技术人员通常理解的相同的含义。将进一步理解的是，诸如在通常使用的字典中定义的那些术语应当被解释为具有与它们在相关技术和本公开的上下文中的含义一致的含义，并且将不被解释为理想化的或过度正式的意义，除非本文中明确地这样定义。
在下面将描述以与在图1至9中的结合附图的本发明的实施例。将参考附图详细描述本发明，其中所描绘的元件不一定按比例示出，并且其中通过几个视图和相同或相似的术语通过相同或相似的附图标记来指定相同或相似的元件。
附图展示了电脑承重结构。然而，本发明的实施例不限于电脑的承重结构。例如，作为家用游戏机的电子设备也可以利用下面描述的承重结构。
图1-3是现有技术的一个示范性实施例的分解图，展示了现有技术中，电路板1、负载物2、支架3、固定板5如何组装起来。
图4、5是现有技术的一个示范性实施例的透视图，分别展示了电路板在水平和竖直位置，主负载如何通过电路板的安装孔(mounting holes)6转移到电子设备的外壳。在水平位置和静止状态下，电路板1不会受到负载物2、支架3、固定板5的拉扯。而在竖直位置或移动环境反复加减速的情况下，电路板1会受到负载物2、支架3、固定板5的静力或拉扯，因为负载物2、支架3、固定板5先通过穿孔固定于电路板2，再通过电路板2之上的安装孔6固定于电子设备外壳。负载物2并未直接固定于电子设备外壳，而是通过电路板2间接的将负载转移到电子设备外壳，而电路板并不适合被设计为承重结构，本身很脆弱，又往往是整个系统的中心。
图6-8是本发明的一个示范性实施例的分解图，展示了固定板5如何被螺丝5固定于电子设备的外壳8。与电路板的安装孔(mounting holes)6相似，外壳8内面分布着与螺丝5配合的结构。当固定板5被固定于外壳8之后，只要固定板5和/或支架3未发生滑动(移动环境较大过载或/和反复震动所导致)，电路板1只须承受自身重量。然而，固定板5的固定方式并不限于螺接，还可通过胶粘、焊接等各种方式固定。
直接将固定板连接到外壳，对于定制的电子设备(譬如：家用游戏机)，很容易实现。然而对于模块化的电子设备，譬如ATX电脑，因为CPU孔位的位置并不固定，外壳8内面用于固定的结构，无法标准化。需要其它方法解决标准化问题。
图9是本发明的另一个示范性实施例的分解图，展示了固定板5，如何与电路板1，通过与电路板1位置相对应的安装孔6，一起被固定于电子设备的外壳8。其中的固定板5，其尺寸不小于所述电路板1，因此可以包含电路板1边缘的对应位置的安装孔6。这样，当电子设备处于竖直位置或移动环境时，支架对固定板5的拉扯，会直接通过安装孔6转移到电子设备的外壳8，只要固定板5未发生严重的形变，固定板5对于电路板1的力会均匀的分散到整个电路板1平面上。固定板5因为结构简单，加强的成本也很低。
以上描述仅是本发明的实施例，并不意在限制本发明的范围。根据本公开的权利要求和说明书的各种变化和修改仍在所要求保护的发明的范围内。此外，每个实施例和权利要求未必包含了所公开的所有优点或特性。此外，摘要和标题仅用于便于搜索专利文献,并且不旨在以任何方式限制所要求保护的发明的范围。
