用于笔记本电脑的转轴装置和笔记本电脑
本申请要求于2017年3月10日提交中国专利局、申请号为201710142496.X、发明名称为"一种笔记本电脑的双轴转轴阻尼结构"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
本申请涉及计算机领域，尤其涉及一种用于笔记本电脑的转轴装置和笔记本电脑。
背景技术
笔记本电脑经过行业多年的积累发展，屏幕与主机的开合角度已经从0°到180°发展至0°至360°，实现了笔记本电脑更多的使用模式，给用户带来了更好的使用体验。
但是，目前市场上出现的多种型号的笔记本电脑均设置两根转轴，每根轴上单独设置阻尼部件以作为笔记本电脑屏幕和主机旋转的扭力产生区域。阻尼部件至少包括螺母、碟簧、凸轮和凹轮四种零件，凹轮、凸轮和碟簧依次组装在轴上，末端通过螺母锁附，如图1所示。凸轮与轴通过轴孔配合固定，与轴一起转动，轴转动时带动凸轮滑出与之配合的凹轮，凸轮与凹轮错位时相互挤压，将挤压力传递至碟簧，碟簧发生形变，让出空间，从而使凸轮可以爬升至凹轮顶面，产生所需要的扭力。
由于阻尼部件中的凸轮和凹轮在转动过程中，其组合高度在一定程度上重叠，所以设置具有这种阻尼部件的笔记本电脑，就需要将两根转轴之间的距离设置的较大，以使笔记本电脑与主机完成360°旋转，这就使制造的笔记本电脑的厚度比较大。

在另一种设计中，转轴装置还包括第一齿轮和第二齿轮，第一齿轮设置在第一转轴上，第二齿轮设置在第二转轴上，且与第一齿轮的位置相对应。以提高采用本发明实施例提供的转轴装置在转动过程中的平稳性。将该转轴装置应用于笔记本电脑，提高了用户开合笔记本电脑的屏幕和/或主机时，用户的手感。
在一种可能的设计中，阻尼部件上方设置有第一外壳，提高外观的美感程度。若阻尼部件上设置储油槽，还可以防止储油槽中的油外漏。同时也避免了阻尼部件的缝隙夹杂异物等问题。

图2为本发明实施例提供的一种转轴装置的结构示意图。如图2所示，该转轴装置包括第一转轴110、第二转轴120、支撑件130、第一锁附件140、第二锁附件150和阻尼部件160。
第一转轴110和第二转轴120通过支撑件130平行设置。第一转轴110和第二转轴120放置在支撑件130(如图3所示)的支撑孔中，与支撑孔间隙配合。第一转轴110和第二转轴120可以在支撑件的支撑孔内自由转动。
另外，在支撑件130的局部区域设置了开槽，该开槽用于穿插或者放置线材料，线材料用于实现笔记本电脑的显示屏幕和主机之间的电信号传输。
第一锁附件140设置在第一转轴110上，第二锁附件150设置在第二转轴120上。第一锁附件140与笔记本电脑的显示屏幕固定连接，第二锁附件150与笔记本电脑的主机固定连接，如图4所示。以便于实现笔记本电脑的显示屏幕和主机相对转动的时候，第一锁附件140和第二锁附件150一起转动，带动第一转轴110和第二转轴120的转动。
阻尼部件160为具有双孔的部件，如图5(a)所示。图5(a)示出阻尼部件包括孔1和孔2。第一转轴110和第二转轴120可以分别放置在阻尼部件的双孔中的一个孔中，如图5(b)所示。阻尼部件160的双孔与第一转轴110和第二转轴120通过过盈配合产生扭力。
在另一实施例中，本发明实施例提供的转轴装置可以同时采用本发明实施例提供的阻尼部件与其他阻尼部件(如单孔的阻尼部件)的组合，即第一转轴110和第二转轴120可以采用的不同的阻尼部件，以实现可以转动的转轴装置。
本发明实施例提供的转轴装置可以对称设置阻尼部件160、第一锁附件140和第二锁附件150，以提高笔记本电脑的显示屏幕和主机相对转动过程中的稳定性。
在本发明的一个实施例中，如图2所示，转轴装置的第一转轴110和第二转轴120上左右两侧可以设置两个阻尼部件160，可以使笔记本电脑的显示屏幕和主机在转动过程中，通过两个阻尼部件与第一转轴110和第二转轴120的过盈配合产生的扭力的合力停留在任何相对夹角的位置。另外，第一锁附件140、第二锁附件150也可以分别在第一转轴110、第二转轴120的左右两侧分别设置一个，以提高笔记本电脑的显示屏幕和主机在开合过程中的稳定性。
本发明实施例提供的用于笔记本电脑的转轴装置，相对于传统应用于笔记本电脑的转轴装置，其降低了转轴的高度。采用本发明实施例提供的转轴装置，制造的笔记本电脑更轻薄，且双轴动地实现了0°至360°的旋转。
如图5(a)和图5(b)所示，阻尼部件160的双孔孔壁上设置有缝隙(包括缝隙1和缝 隙2)。孔壁在缝隙的两侧可形成弹性区域。从理论上，如果设计的孔径小于轴径，那么就存在轴的外壁与孔的内壁的干涉区域，那么弹性区域的存在可以使轴径大于孔径时实现阻尼部件与第一转轴和第二转轴的装配。因弹性区域的形变而使轴与孔内壁之间产生摩擦力，从而使转轴具备扭力。
采用本发明实施例提供的阻尼部件，在笔记本电脑的显示屏幕与主机开合时，产生的扭力稳定，且扭力能快速上升达到预设值，如图6所示，图6为本发明实施例提供的角度与扭力的关系图。而且，本发明实施例提供的阻尼部件的结构，相比由至少包括螺母，碟簧，凸轮，凹轮的传统阻尼部件的结构要简单。
可选地，在本发明实施例中，阻尼部件的壁厚可以设置为等壁厚，也可以设置为渐变壁厚，如图7(a)和图7(b)所示。其中图7(a)为本发明实施例提供的一种等壁厚的阻尼部件的示意图；图7(b)为本发明实施例提供的一种渐变壁厚的阻尼部件示意图。
在满足扭力要求的前提下，采用渐变壁厚的阻尼部件可以降低整个阻尼部件的高度，进一步降低笔记本电脑的厚度。如图7(a)和图7(b)对比，等壁厚的阻尼部件的整体高度要比渐变壁厚的阻尼部件的整体高度高出一部分，高出部分大约为0.5mm-1mm。
与传统的双轴360°旋转的独立设置的阻尼部件相比，传统阻尼部件需要更多的零件，组装更加复杂，如图1所示，提供扭力的零件至少包括螺母，碟簧，凸轮，凹轮等。传统的双轴阻尼部件各自独立，在高度方向产生叠加，在于轴一起转动时，凸轮需要爬升至凹轮顶面，此时，从整体阻尼部件整体上，阻尼部件的高度增加。由于凹轮和凸轮配合处需要较大的结构强度，受限于转轴寿命及扭力限制，目前业内已知的阻尼部件的外径(或者高度)大于5.2mm，而实现同能扭力条件下，本发明实施例提供的阻尼部件的外径可控制在3.5mm。从尺寸上，采用本发明实施例提供的阻尼部件，可以降低制造出的笔记本电脑的厚度。
除此外，如图1所示，传统转轴装置中的异形轴设计，为了保证异形轴的强度，其轴的轴径不能制作的太小，目前业内最小的轴径值需要大于4mm；而本发明实施例提供的转轴装置中的第一转轴和第二转轴的轴径可以控制在2mm。相比传统的轴径要小，采用本发明实施例提供的转轴装置，进一步降低了笔记本电脑的厚度。
另外，就笔记本电脑的显示屏幕和主机的开合体验对比而言，传统阻尼部件提供的扭力是随着凹轮、凸轮干涉量的增加而增加的，扭力爬升比较慢，如图8所示。且如图8所示，由于传统阻尼部件有凹轮、凸轮等部件组成，在笔记本电脑的显示屏幕与主机被打开或者关闭的过程中，扭力不平滑，且在特定位置会产生个峰。而本发明实施例提供的阻尼部件，由于其轴孔干涉稳定，在转轴转动时，扭力马上产生，如图6所示，且整个转动过程扭力恒定。与传统的阻尼部件相比，本发明实施例提供的阻尼组件可以给用户在开合笔记本电脑的过程中带来的手感体验更好。
就转轴的寿命而言，传统的阻尼部件中的凹轮和凸轮因为在笔记本电脑开合过程中扭力的不断变化，会加速凹轮与凸轮的磨损，从而减少转轴寿命。目前业内转轴的寿在20000次的开合，而本发明实施例提供的阻尼部件可使转轴的寿命可达到25000次至30000次的开合。本发明实施例提供的组件可提高转轴的寿命。
可选地，在本发明的一个实施例中，阻尼部件上还可以设置储油槽。在储油槽中增加润滑油，润滑油可以使阻尼部件与第一转轴和第二转轴之间的摩擦力减小。同时，润滑油 还可以填充因加工误差带来的瑕疵区域。
在本发明的一个实施例中，储油槽可以如图9(a)所示。在第一转轴、第二转轴与阻尼部件配合区域设置该储油槽，储油槽为多个储油槽，储油槽中可放置润滑油。润滑油的存储量取决于储油槽的宽度、深度以及储油槽的数量。储油槽的宽度、深度以及数量可以根据实际产品，即转轴装置或应用该转轴装置的产品(例如笔记本电脑)对扭力的需求来确定。对于有比较大扭力需求的产品，在设置该产品时，可以增加储油槽的数量、增加储油槽的宽度和深度的尺寸。对于有比较小扭力的产品，在设置该产品时，可以适当的减小储油槽的数量，储油槽的宽度和深度的尺寸。
需要说明的是，储油槽的分布可以采用在扭力区域均匀分布的方式，如图10(a)所示，也可以采用不等间距分布，具体分布方式可以根据产品扭力需求做调整。
图9(b)和图9(c)为储油槽外设置了外壳的结构示意图，具体请参见后续描述。
采用本发明实施例提供的阻尼装置，可以使笔记本电脑的显示屏幕和主机开合时更加顺滑，扭力更加平稳，开合笔记本电脑的显示屏幕和主机时的手感更好，提高了用户体验。同时，进一步提高了第一转轴和第二转轴的使用寿命。另外，可以通过控制设置在阻尼部件上的储油槽的深度和宽度，来控制润滑油量，进一步来控制转轴实现不同扭力。
可选地，如图2所示，在本发明实施例中，转轴装置还可以包括第一齿轮和第二齿轮。第一齿轮设置在第一转轴上，第二齿轮设置在第二转轴上，且与第一齿轮的位置相对应，用于实现笔记本电脑的显示屏幕与主机转动时，第一齿轮和第二齿轮的相互转动。
采用本发明实施例提供的转轴装置，可以提高笔记本电脑的显示屏幕和主机开合过程中的的稳定性，提高了用户体验。需要说明的是，采用本发明实施例提供的转轴装置，在用户使用笔记本电脑，进行开合操作过程中，笔记本电脑可以依第一转轴或者第二转轴中的任一轴为旋转轴旋转0°至360°。笔记本电脑的显示屏幕和主机也可以同时跟随第一转轴和第二转轴的转动完成开合，实现0°至360°的旋转。同时实现了笔记本电脑的多种使用状态，如图10(a)-图10(g)所示。
其中，图10(a)为本发明实施例提供的一种笔记本电脑的显示屏幕和主机处于闭合状态，即未打开状态的示意图；图10(b)为本发明实施例提供的一种笔记本电脑的显示屏幕和主机被打开大于0°小于90°的状态示意图；图10(c)为本发明实施例提供的一种笔记本电脑的显示屏幕和主机被打开90°状态示意图；图10(d)为本发明实施例提供的一种笔记本电脑的显示屏幕和主机被打开180°的状态示意图；图10(e)为本发明实施例提供的一种笔记本电脑的显示屏幕和主机被打开大于270°小于360°的状态示意图；图10(f)为本发明实施例提供的另一种笔记本电脑的显示屏幕和主机被打开大于270°小于360°的状态示意图；图10(g)为本发明实施例提供的一种笔记本电脑的显示屏幕和主机被打开360°的状态示意图。
本发明实施例提供的转轴装置，作为一个整体独立于笔记本电脑的壳体之外，除第一锁附件和第二锁附件之外，不需要为壳体做避让，不破坏壳体的完整性。
还需要说明的是，本发明实施例提供的转轴装置，如图11所示。转轴装置的整体高度的尺寸S1可以控制在7mm以下，其尺寸的大小取决于第一转轴和第二转轴的外径大小，以及阻尼部件的孔壁厚度。
上文提到，阻尼部件上设置有储油槽，可以通过调整阻尼部件的长度S2来获得不同 大小的扭力。调整第一锁附件或第二锁附件的长度S3可以获得与笔记本电脑的显示屏幕和主机的不同锁附强度。调整第一齿轮或第二齿轮的长度S4可以获得最佳的传动平顺性。另外，支撑件的长度可以通过阻尼部件的长度S2，第一锁附件或第二锁附件的长度S3，以及第一齿轮或第二齿轮的长度S4的长度来调整，可进一步实现比例的合适度，增加视觉上的舒适度。
可选地，在本发明实施例中，在阻尼部件的上方设置有第一外壳，所述第一外壳可以通过胶，焊接，过盈配合等多种方式与阻尼部件固定在一起，对阻尼部件起到保护作用，减少阻尼部件漏油，阻尼部件的缝隙夹杂异物等问题，具体可参考图9(b)和图9(c)所示。
可选地，在本发明实施例中，转轴装置中的第一齿轮和第二齿轮可以与支撑件相邻设置，在第一齿轮和第二齿轮，及支撑件上设置有第二外壳，其第二外壳使第一齿轮和第二齿轮，支撑件变为内置件起到了对第一齿轮和第二齿轮，及其支撑件的保护。外壳的选材及加工方式可以自由选择，且不用做表面处理，可以降低支撑件的成本。
阻尼部件、第一齿轮和第二齿轮，以及支撑件的外壳可以通过表面处理，与第一锁附件和第二锁附件、笔记本电脑的壳体达成一致的外观效果，增加笔记本电脑外观的整体性，提高笔记本电脑的外观效果，需要说明的是，在本发明实施例中，可以采用多种表面处理，提高笔记本电脑的外观效果，在本发明实施例中，对表面处理的方式不作限制。
还需说明的是，在本发明实施例中，转轴装置还可以采用不同的阻尼部件，例如，转轴装置中的转轴可以采用本发明实施例提供的阻尼部件和传统的阻尼部件，或者本发明实施例提供的阻尼部件和单孔的阻尼部件的组合，即两个转轴采用不同的阻尼部件，以实现转轴装置的转动。
本发明实施例还提供了一种笔记本电脑，该笔记本电脑包括图2至图11所述的转轴装置，以及用于显示信息的显示屏幕和主机。
在本发明实施例中，通过设置在转轴装置上的支撑件实现显示屏幕和所述主机间线路的连接，完成点信号的输入和输出。
该笔记本电脑可以依据转轴装置完成笔记本电脑的显示屏幕和主机的0°至360°的旋转，实现图10(a)至图10(g)所示的任一种使用状态，提高了用户体验。
