发明详述
为了保护电子设备免受机械应力造成的损坏或故障,在不显著增加设备的成本或重量的情况下,提高这些电子设备的机械强度将是有帮助的。
几种电子设备如台式电脑、笔记本电脑、手持式移动终端、通讯元件(例如电话)等等在客户使用过程中、在运输过程中或在储存过程中通常容易遭受物理损坏(例如设备失效或故障)。该失效或故障可能因内部组件损坏而发生。
电子设备通常通过将内部电器组件,如中央处理器(CPU)板、显示器、键盘和/或内部布线包封在塑料或另一结构材料制成的外壳中来组装。该包封件通常用作保护性外壳,但是不具有处理任何显著的机械应力的能力,因为该保护性外壳可能具有小于大约30Shore A的硬度。
因此,电子设备需要具有基材包封材料,其可以处理机械应力,所述机械应力包括但不限于电子设备的摔落或物体掉落在电子设备上。
在一些实例中,描述了一种电子设备,其包括:被能量吸收材料至少部分包封的基材,其中该能量吸收材料整体或可拆卸地附着到基材上,其中该基材是碳纤维、玻璃、陶瓷、金属、复合材料或其混合物,并且其中该能量吸收材料包含至少一种热塑性聚合物。
该电子设备不限于并可包括台式电脑、笔记本电脑、手机、手持式设备和打印设备。
在一些实例中,该能量吸收材料整体附着到基材上。
该基材可包括电子设备的任何内部组件或平坦表面,例如CPU板、显示器和键盘。
在一些实例中,所述至少一种热塑性聚合物还包含增韧剂。
在一些实例中,增韧剂是氟化烃、天然橡胶、聚异戊二烯、聚氯丁二烯、苯乙烯-丁二烯橡胶、丁腈橡胶、乙烯丙烯二烯单体橡胶、聚丁二烯/丁基橡胶、表氯醇、硅橡胶或其组合。
在一些实例中,增韧剂以基于能量吸收材料的总重量计大约20-60重量%的量存在于能量吸收材料中,或增韧剂以基于能量吸收材料的总重量计大约25-55重量%的量存在于能量吸收材料中,或增韧剂以基于能量吸收材料的总重量计大约30-50重量%的量存在于能量吸收材料中,或增韧剂以基于能量吸收材料的总重量计大约35-45重量%的量存在于能量吸收材料中,或增韧剂以基于能量吸收材料的总重量计大约10-20重量%的量存在于能量吸收材料中,或增韧剂以基于能量吸收材料的总重量计大约5-10重量%的量存在于能量吸收材料中,或增韧剂以基于能量吸收材料的总重量计大约60-70重量%的量存在于能量吸收材料中。

本文中所用的“被(一种或多种)能量吸收材料包封的(一个或多个)基材”是指被至少一种能量吸收材料至少部分包封的电子设备基材。但是,要理解的是,可以允许在能量吸收材料中存在任何端口接入口或其它开口以便于连接和/或执行功能。
本文中所用的“部分包封”是指基材在该基材的至少一个表面上但并非该基材的所有表面上被能量吸收材料包封。要理解的是,本文中所用的基材可以具有超过四个侧面。但是,要理解的是,可以允许在能量吸收材料中存在任何端口接入口或其它开口以便于连接和/或执行功能。
在一些实例中,基材在该基材的底表面上被能量吸收材料包封(例如图7和图7A)。

在另一方法中,可以将能量吸收材料浇铸在基材周围。该能量吸收材料可以在封闭模具中固化。浇铸法可以在氮气下进行。一部分能量吸收材料可以在模具中在基材上成型,随后可以将另一部分能量吸收材料组装到第一部分上并固化以形成成品包封件。在能量吸收材料在基材的表面上成型之前,可以对基材的表面进行表面处理,以提高基材与包封件之间的粘附力。

在一些实例中,能量吸收材料可以充当包封基材与接触点(例如地面或掉落在电子设备上的物体)之间的屏障。能量吸收材料可以吸收冲击能量,而不会导致玻璃或陶瓷基材破裂和金属或复合材料基材变形。
用于上文均进行了描述的基材和能量吸收材料的材料可以购自制造商或可以采用已知技术/方法来制备。
在一些实例中,能量吸收材料在施加动态应力后可以恢复形状。能量吸收材料可以进一步提供保护电子设备的轻量化解决方案。

在描述和要求保护本文中公开的实例时,单数形式“一”、“一个/种”和“该”包括复数指示物,除非上下文另行明确规定。
要理解的是,浓度、量和其它数值数据在本文中可能以范围格式表示或呈现。要理解的是,这样的范围格式仅为方便和简要起见而使用,因此应灵活解释为不仅包括作为该范围的端点明确列举的数值,还包括该范围内包含的所有独立的数值或子范围,就像明确列举各数值和子范围那样。作为一个示例,“大约1重量%至大约5重量%”的数值范围应被解释为不仅包括大约1重量%至大约5重量%的明确列举的值,而且还包括在所示范围内的独立值和子范围。因此,在这一数值范围中包括独立值,如2、3.5和4,以及子范围,如1-3、2-4和3-5等。这同样适用于列举单个数值的范围。
本说明书通篇中提及“一个实例”、“一些实例”、“另一实例”、“实例”等等是指结合该实例描述的特定要素(例如特征、结构和/或特性)包含在本文中描述的至少一个实例中,并可以或可以不存在于其它实例中。此外,要理解的是,除非上下文另行明确规定,否则在各个实例中,对任何实例所描述的要素可以以任何合适的方式结合。
除非另行说明,否则本文中提及的组分的“重量%”是指该组分的重量占包含该组分的整个组合物的百分比。例如,本文中提及例如分散在液体组合物中的固体材料(如(一种或多种)聚氨酯或(一种或多种)着色剂)的“重量%”是指那些固体在组合物中的重量百分比,而不是指该固体的量占组合物的总非挥发性固体的百分比。
如果在本文中提及标准测试,除非另行说明,否则所提及的测试的版本是提交本专利申请时的最近版本。
除非另行指示,否则本文中和下面的实施例中公开的所有量以重量%计。
虽然已经详细描述了多个实例,要理解的是,可以修改所公开的实例。因此,前面的描述被认为是非限制性的。
