Description

盖板玻璃组件
本申请要求于2016年01月29日提交中国专利局、申请号为201610063807.9、发明名称为“盖板玻璃组件”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
本发明涉及终端终端设备领域，并且更具体地，涉及一种盖板玻璃组件。
背景技术
手机跌落或手机弯折的可靠性是用户感知最明显的部分，也是用户眼中质量可靠性的代名词。日常使用中的跌落，大部分是从手中、背包或者桌子上掉落，高度通常约为0.8m～1.2m，从P8手机的跌落测试(Drop To Failure，DTF)数据来看，仅能通过0.7m。现有手机开发过程中，整机可靠性测试失效是影响研发项目进度的最主要原因之一，而可靠性测试失效中80％以上为跌落测试失效，其中，跌落测试更严酷的是四个角的跌落。
现有技术中，旗舰机采用接触玻璃下表面直接点固化胶或者玻璃侧面点固化胶，跌落性能的提升主要依赖于玻璃本身。
发明内容
本发明实施例提供了一种盖板玻璃组件，能够提高盖板玻璃的抗跌落性能。
第一方面，提供了一种盖板玻璃组件，该盖板玻璃组件包括盖板玻璃210，所述盖板玻璃210包括至少一个转角；缓冲构件220，用于对所述盖板玻璃210的所述至少一个转角中的每个转角处产生作用力F，且所述作用力F的方向与所述盖板玻璃210的主体所在的平面成夹角α，其中，所述夹角α满足：0°＜α＜90°。
对于包括转角的盖板玻璃，在跌落时角落的破损较多，因此本发明实施例通过增加一个缓冲构件可以使得盖板玻璃210在转角处的受力发生变化，例如，对转角处的作用力F从现有技术中的直接水平作用，改为与盖板玻璃210的主体所在水平面的夹角为大于0°且小于90°的作用力，这样的作用 力F可以分解为水平作用力F1＝Fcosα和竖直向上的作用力F2＝Fsinα，这个竖直向上的分力Fsinα可以使得盖板玻璃210变形向上微拱，而水平分力Fcosα相对现有技术中直接作用于该盖板玻璃210的作用力F要小，相对现有技术中的正弦曲线变形，本发明实施例能够明显减少了盖板玻璃的变形状况，从而达到在跌落时保护盖板玻璃的目的。
结合第一方面，在第一方面的第一种可能的实现方式中，所述盖板玻璃组件还包括：矩形边框230，所述矩形边框230的内壁四周设置为矩形台阶式结构，且所述盖板玻璃210通过弹性胶240粘结于所述矩形台阶式结构，所述缓冲构件220设置于所述矩形台阶式结构。
该矩形边框230的内壁四周设置为台阶式结构，该台阶式结构可用于支撑该盖板玻璃210，也就是说，该矩形边框230的内壁四周再设置一个矩形内框与前述矩形边框230形成台阶式结构，且该矩形内框的上表面与该矩形边框230的内壁相互垂直，这样该盖板玻璃210的下表面的四周与该矩形边框的上表面接触。弹性胶240可以缓冲矩形边框230对盖板玻璃210的作用力。具体地，终端设备在跌落的过程中，具有向下的加速度，刚接触地面弹性胶240发生形变，到达最低点时，由于弹性胶240具有弹性性能可以恢复原状，进而给盖板玻璃210竖直向上的作用力F3。此外，由前述可知，盖板玻璃210还受到缓冲构件220对盖板玻璃210竖直向上的作用力Fsinα，通过这两个竖直向上的作用力的合力F3+Fsinα，使得盖板玻璃210变形向上微拱，从而进一步达到保护盖板玻璃的目的。
结合第一方面，在第一方面的第二种可能的实现方式中，所述盖板玻璃210为矩形结构的盖板玻璃。
结合第一方面及第一方面的第一种可能的实现方式或第一方面的第二种可能的实现方式，在第一方面的第三种可能的实现方式中，该盖板玻璃210与该缓冲构件220为面面接触。
为了使盖板玻璃210与缓冲构件220更容易契合，更好的保护盖板玻璃，盖板玻璃210上与缓冲构件220连接的部位，可以设置成与该缓冲构件220的接触面平行的平面，这样可以进一步保护盖板玻璃。
结合第一方面的第一种可能的实现方式，在第一方面的第四种可能的实现方式中，所述盖板玻璃210为矩形结构的盖板玻璃，所述矩形结构的盖板玻璃的四个角分别为圆弧倒角，所述缓冲构件220设置在所述盖板玻璃210 的四个圆弧倒角处，且所述缓冲构件220上接触所述盖板玻璃210的表面所在的平面与所述矩形边框230的内壁所在的平面成所述夹角α。
在本发明实施例中，矩形结构的盖板玻璃的四个角分别为圆弧倒角，底面为直角三角形的直三棱柱即缓冲构件220的高度可以根据具体应用进行设定，例如，该底面为直角三角形的直三棱柱的高度可以是0.5mm。这样，在盖板玻璃210的四个圆弧倒角周围可以以均匀的间隔布置该缓冲构件2。在本发明实施例中，该间隔距离可以根据实际应用进行设定，本发明对此不进行限定，例如，该间隔距离可以设定为1mm，进而提高终端设备在跌落过程中四个角落的抗跌落性能。
结合第一方面，及第一方面的第一种可能的实现方式至第一方面的第四种可能的实现方式中的任一种可能的实现方式，在第一方面的第五种可能的实现方式中，该夹角α满足：20°≤α≤30°。
缓冲构件220对盖板玻璃210产生作用力F，该作用力F与盖板玻璃210所在的平面夹角可以进一步限定为20°≤α≤30°，即该缓冲构件220上与该盖板玻璃210接触的表面设置为与该矩形边框230的内壁所在的平面成夹角α，优选地的该夹角α的范围为20度到30度，该锐角α可以是20度、25度、28度或30度等，本发明实施例并不限于此。
结合第一方面及第一方面的第一种可能的实现方式至第一方面的第五种可能的实现方式中的任一种可能的实现方式，在第一方面的第六种可能的实现方式中，该缓冲构件220的材质为聚碳酸酯PC或丙烯脂-丁二烯-苯乙烯共聚物PA。
该缓冲构件220的材质可以是聚碳酸酯PC、丙烯脂-丁二烯-苯乙烯共聚物PA，或者PC和PA的合成材料。应理解，该缓冲构件220还可以是其他材质，本发明对此不进行限定。
结合第一方面及第一方面的第一种可能的实现方式至第一方面的第六种可能的实现方式中的任一种可能的实现方式，在第一方面的第七种可能的实现方式中，该矩形边框230与该缓冲构件220为一体式。
具体而言，终端设备的该矩形边框230与该缓冲构件220可以集成为一体，本发明对此不进行限定。例如，对于金属材质的矩形边框230与PC材质的缓冲构件220，可以通过双色注塑、纳米注塑或嵌件成型等工艺将矩形边框230与缓冲构件220注塑为一体。
第二方面，提供了一种终端设备，包括：

基于上述技术方案，本发明实施例的盖板玻璃组件，通过增加缓冲构件，盖板玻璃在跌落时的水平受力减少，同时受到竖直向上的分力使得盖板玻璃变形向上微拱，从而达到保护盖板玻璃的目的，提升跌落性能。

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，所描述的实施例是本发明一部分实施例，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作出创 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。
在本发明实施例中的终端设备可以包括但不限于手机、平板电脑、电子书、移动台等，虽然附图中示出的为移动电话，但本发明实施例并不对此进行任何限定。
该终端设备除了包括盖板玻璃、矩形边框，还包括其他部件，为了简洁，在此不再赘述。
该矩形边框可以是用于终端设备中放置印制电路板、芯片或电池的支持构件，或者用于支持终端设备屏幕的支持构件，例如，手机中框、手机屏支撑板、平板电脑或电脑屏支撑板等，本发明实施例并不限于此。该矩形边框可以为手机、平板电脑或电脑的后壳等。
图1是现有技术中在盖板玻璃下面点固化胶的盖板玻璃组件的局部截面图，如图1所示，盖板玻璃组件包括盖板玻璃110，矩形边框120和固化胶130。
现有技术中终端设备在跌落时，该矩形边框120对该盖板玻璃110产生作用力F。图2为盖板玻璃组件在跌落时盖板玻璃的受力分析示意图，该作用力F将毫无缓冲的传递给盖板玻璃110，给盖板玻璃110一个最大的作用力，如果该作用力超过盖板玻璃110本身所能承受的强度范围时，盖板玻璃110将破裂。
此外，由于盖板玻璃110和矩形边框120之间有固化胶130紧紧拉住，该固化胶130受力后不会发生形变，或者发生形变后不会恢复原状，从而使该盖板玻璃110在受如图2所示的向右的作用力F时，加速了该盖板玻璃110本体上下扭曲变形，图3为在跌落时的盖板玻璃变形的示意图。该盖板玻璃110受力F后，将会如正弦曲线变形图3中的虚线所示，从而加速了盖板玻璃的破裂。
本发明实施例对该盖板玻璃组件的描述以该终端设备置于水平桌面进行描述。其中，竖直方向与重力方向相同，水平方向为平行于水平桌面的方向。
图4示出了根据本发明实施例的一种盖板玻璃组件200的局部截面图。如图4所示，该盖板玻璃组件200包括：
盖板玻璃210，所述盖板玻璃210包括至少一个转角；
缓冲构件220，用于对所述盖板玻璃210的所述至少一个转角中的每个 转角处产生作用力F，且所述作用力F的方向与所述盖板玻璃210的主体所在的平面成夹角α，其中，所述夹角α满足：0°＜α＜90°。
具体而言，对于包括至少一个转角的盖板玻璃，在跌落时角落的破损较多，因此本发明实施例通过增加一个缓冲构件可以使得盖板玻璃210在转角处的受力发生变化，例如，对转角处的作用力F从现有技术中的直接水平作用，改为与盖板玻璃210的主体所在水平面的夹角为大于0°且小于90°的作用力，这样的作用力F可以分解为水平作用力F1＝Fcosα和竖直向上的作用力F2＝Fsinα，这个竖直向上的分力Fsinα可以使得盖板玻璃210变形向上微拱，而水平分力Fcosα相对现有技术中直接作用于该盖板玻璃210的作用力F要小，相对现有技术中的正弦曲线变形，本发明实施例能够明显减少了盖板玻璃210的变形状况如图5中的虚线所示，从而达到在跌落时保护盖板玻璃的目的。
例如，若α为45°时，则F1＝Fcosα＝0.7F＜F，即该缓冲构件220能够减少对盖板玻璃210的水平作用力。
该缓冲构件220可以为底面是直角三角形的实心直三棱柱，或者该缓冲构件220也可以为有三个平面构成的底面为直角三角形的空心三棱柱，或者是仅有一个斜面与该矩形边框230的内壁所在的平面成锐角，为了描述方便，下述实施例以该缓冲构件220为底面是直角三角形的实心直三棱柱为例进行说明，但本发明对此并不限定。
应理解，在具体的终端设备中，终端设备的各个构件相互之间的连接会存在缝隙，该缝隙可以缓冲构件之间的相互作用力，以及可以使两个构件之间更好的契合，便于各构件的装配。例如，在实际生产的终端设备中缓冲构件220和盖板玻璃210之间都可能设置缝隙。该缝隙的宽度可以根据实际应用进行配置，例如，可以设置为0.05mm等，本发明对此不进行限定。
因此，本发明实施例的盖板玻璃组件，通过增加缓冲构件，盖板玻璃在跌落时的水平受力减少，同时受到竖直向上的分力使得盖板玻璃变形向上微拱，从而达到保护盖板玻璃的目的，提升盖板玻璃的跌落性能。
可选地，所述盖板玻璃组件还包括：
矩形边框230，所述矩形边框230的内壁四周设置为矩形台阶式结构，且所述盖板玻璃210通过弹性胶240粘结于所述矩形台阶式结构，所述缓冲构件220设置于所述矩形台阶式结构。
具体而言，盖板玻璃210的边框可以设置为矩形，例如，矩形边框230的内壁四周可以设置为台阶式结构，该台阶式结构可以用于支撑该盖板玻璃210，也就是说，该矩形边框230的内壁四周可以再设置一个矩形内框与前述矩形边框230形成台阶式结构，且该矩形内框的上表面与该矩形边框230的内壁相互垂直，这样该盖板玻璃210的下表面的四周与该矩形边框230的上表面接触，并通过弹性胶240粘结在该矩形台阶式结构上。
如图6为根据本发明实施例的局部截面图，弹性胶240可以缓冲矩形边框230对盖板玻璃210的作用力。具体地，终端设备在跌落的过程中，具有向下的加速度，刚接触地面弹性胶240发生形变，到达最低点时，由于弹性胶240具有弹性性能可以恢复原状，进而给盖板玻璃210竖直向上的作用力F3。此外，由前述可知，盖板玻璃210还受到缓冲构件220对盖板玻璃210竖直向上的作用力Fsinα，通过这两个竖直向上的作用力的合力F3+Fsinα如图7所示，使得盖板玻璃210变形向上微拱，从而进一步达到保护盖板玻璃的目的。
可选地，该盖板玻璃210可以为矩形结构的盖板玻璃。
应理解，该盖板玻璃210和边框还可以是其他形状，本发明对此不进行限定，为了描述方便，下述实施例以盖板玻璃210为矩形结构和矩形边框230为例进行说明，但本发明对此并不限定。
可选地，该弹性胶240可以是弹性胶水，例如，橡胶胶水或聚氨酯胶等。只要能满足发生一定的形变后，可以恢复原状即具有弹性性能，本发明对此不进行限定。
应注意，在本发明实施例中，该弹性胶水可以沿着盖板玻璃210的下表面和矩形边框230的台阶式结构接触的四周边缘以相同的厚度均匀的涂覆，以不影响盖板玻璃210的显示功能为准，本发明对此不进行限定。
还应理解，该矩形边框230的最高位置可以低于、平齐或高于该盖板玻璃210的上表面，本发明对此不进行限定。
可选地，该盖板玻璃210与该缓冲构件220可以是面面接触。
具体而言，图8为根据本发明又一个实施例的局部截面图。为了使盖板玻璃210与缓冲构件220更容易契合，更好的保护盖板玻璃210，盖板玻璃210上与缓冲构件220连接的部位，可以设置成与该缓冲构件220的接触面平行的平面，这样可以进一步保护盖板玻璃。相应地，该盖板玻璃210与缓 冲构件220之间也可以存在0.05mm的缝隙。
可选地，所述盖板玻璃210为矩形结构的盖板玻璃，所述矩形结构的盖板玻璃的四个角分别为圆弧倒角，所述缓冲构件220设置在所述盖板玻璃210的四个圆弧倒角处，且所述缓冲构件220上接触所述盖板玻璃210的表面所在的平面与所述矩形边框230的内壁所在的平面成所述夹角α。
具体而言，在本发明实施例中，该矩形结构的盖板玻璃的四个角分别为圆弧倒角，底面为直角三角形的直三棱柱即缓冲构件220的高度可以根据具体应用进行设定(如图9为本发明实施例的盖板玻璃组件的局部剖视图)，例如，该底面为直角三角形的直三棱柱的高度可以是0.5mm，本发明对此不进行限定。这样，在盖板玻璃210的四个圆弧倒角周围可以以均匀的间隔布置该缓冲构件220，如图10所示为盖板玻璃组件的局部正视示意图。在本发明实施例中，该间隔距离可以根据实际应用进行设定，本发明对此不进行限定，例如，该间隔距离可以设定为1mm，进而提高终端设备在跌落过程中四个角落的抗跌落性能。
应注意，为了减少盖板玻璃210的受损，也可以沿着盖板玻璃210周围一圈间隔的设置将该缓冲构件220，本发明实施例不仅限于四个角落处。还应注意，若根据需要该间隔距离也可以不均匀设置，本发明对此不进行限定。
还应理解，在实际应用中，为了使得缓冲构件220不锋利，增加该缓冲构件220的可接触性，通常在缓冲构件220上的与盖板玻璃210接触的表面的四个角做出倒角，该倒角可以设置成45度、50度或60度等，本发明对此不进行限定。
可选地，该夹角α满足：20°≤α≤30°。
具体而言，缓冲构件220对盖板玻璃210产生作用力F，该作用力F与盖板玻璃210所在的平面夹角可以进一步限定为20°≤α≤30°。例如，该缓冲构件220上与该盖板玻璃210接触的表面设置为与该矩形边框230的内壁所在的平面成夹角α，优选地的该夹角α的范围为20度到30度，该锐角α可以是20度、25度、28度或30度等，本发明实施例并不限于此。
可选地，该缓冲构件220的材质为聚碳酸酯PC或丙烯脂-丁二烯-苯乙烯共聚物PA。
具体而言，该缓冲构件220的材质可以是聚碳酸酯PC、丙烯脂-丁二烯-苯乙烯共聚物PA，或者PC和PA的合成材料。
应理解，该缓冲构件220还可以是橡胶等其他材质，本发明对此不进行限定。
可选地，该矩形边框230可以与该缓冲构件220为一体式。
具体而言，矩形边框230与该缓冲构件220可以集成为一体。例如，对于金属材质的矩形边框230与PC材质的缓冲构件220，可以通过双色注塑、纳米注塑或嵌件成型(insert molding)等工艺将矩形边框230与缓冲构件220注塑为一体。
因此，本发明实施例的盖板玻璃组件，通过增加缓冲构件，盖板玻璃在跌落时的水平受力减少，同时受到竖直向上的分力。此外，由于弹性胶具有的弹性性能，也能够对盖板玻璃产生竖直向上的分力。这两个竖直向上的分力的合力使得盖板玻璃变形向上微拱，从而能够进一步保护盖板玻璃，提升盖板玻璃的跌落性能。
本发明实施例提供了一种终端设备(如图11所示)，包括根据前述任一项的盖板玻璃组件、端盖、显示屏、电池和芯片，该盖板玻璃组件的内侧设置该显示屏，该显示屏内侧设置该电池和芯片，且该盖板玻璃组件、该显示屏、该电池和芯片在该端盖的内侧(如图12为终端设备的局部放大图)。
所属领域的技术人员可以清楚地了解到，为了描述的方便和简洁，上述描述的***、盖板玻璃组件和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
