Description

移动终端及其显示屏组件 技术领域
本发明涉及移动终端技术领域。
背景技术
一般的移动终端包括盖板和显示屏，盖板盖设于显示屏上。在盖板与显示屏的组装过程中，显示屏在盖板上难以实现对中。
发明内容
基于此，有必要提供一种移动终端及其显示屏组件。
一种显示屏组件，用于与移动终端的后壳连接，所述显示屏组件包括：
显示屏；及
盖板，盖设于所述显示屏上；所述盖板包括主体部和边沿部，所述边沿部设置于所述主体部的边缘并与所述主体部连接；所述主体部具有朝向所述后壳的第一表面和背向所述后壳的第二表面；所述边沿部向所述第一表面的一侧弯曲以凸出于所述第一表面上，且所述边沿部与所述第一表面形成容置槽，所述显示屏至少部分收容于所述容置槽内，所述边沿部用于与所述后壳连接；所述主体部的朝向所述显示屏的一侧开设有沉槽，所述第一表面为所述沉槽的底壁，所述显示屏至少部分收容于所述沉槽内；所述显示屏在主平面上的正投影与所述沉槽在主平面上的正投影重合，所述主平面为垂直于所述移动终端的厚度方向的平面。
上述移动终端及其显示屏组件，显示屏组件的盖板包括主体部和边沿部，由于边沿部向后壳的一侧凸出于第一表面上形成容置槽，容置槽为显示屏的提供了安装空间，因此可以减小后壳在移动终端的厚度方向上的尺寸，以使移动终端的外观更加简洁。由于主体部的朝向显示屏的一侧开设有沉槽，显 示屏至少部分收容于沉槽内，沉槽可以与显示屏匹配，以利于显示屏在盖板上的定位，并有利于盖板与显示屏的对中。

(5)常规膝上型和/或掌上型无线电电话收发器等。
参考图1和图2，在一实施例中，移动终端10为手机。移动终端10包括后壳100和显示屏组件200，后壳100盖设于显示屏组件200的一侧并与显示屏组件200连接。后壳100可以对显示屏组件200起到支撑和保护作用。在一实施例中，后壳100大致呈圆角矩形状，后壳100向远离显示屏组件200的一侧外凸，后壳100与显示屏组件200之间形成容纳空间，该容纳空间可用于收容移动终端10的电池和主板等元器件。进一步，参考图3和图4，在一实施例中，后壳100可以包括中框110和电池盖120，显示屏组件200和电池盖120分别与中框110连接，且中框110位于电池盖120与显示屏组件200之间。
在一实施例中，中框110大致呈矩形框状，中框110设于显示屏组件200外周，中框110的内侧可以设置支撑结构。在一实施例中，中框110为金属材质例如铝合金，中框110上通过注塑成型工艺可形成复杂的支撑结构，移动终端10的电池和主板等元器件可以固定于支撑结构上。在一实施例中，中框110也可以为其他材质例如不锈钢或陶瓷。在一实施例中，电池盖120的材质为玻璃，玻璃可以为有色玻璃，也可以为无色玻璃。玻璃可以为透明状，也可以为非透明状。在一实施例中，中框110的外表面的颜色与电池盖120 的外表面的颜色的色差值ΔE大于2.5。中框110的外表面的颜色与电池盖120的外表面的颜色的色差值ΔE处于上述范围时，中框110的外表面与电池盖120的外表面在视觉上有明显的色差，从而可以美化移动终端10的外观。进一步，参考图5和图6，在一实施例中，电池盖120与中框110一体成型，电池盖120和中框110的材质均为铝合金或不锈钢或陶瓷或玻璃，上述结构有利于后壳100的加工成型，并可使得移动终端10的外观较为简洁和一体化。
参考图3和图4，在一实施例中，显示屏组件200包括显示屏210和盖板220。显示屏210位于盖板220的朝向后壳100的一侧，盖板220盖设于显示屏210上并与后壳100连接。显示屏210可以显示信息，并可提供与用户交互的界面。在一实施例中，盖板220包括主体部221和边沿部223，边沿部223设置于主体部221的边缘并与主体部221连接。在一实施例中，主体部221和边沿部223的材质均为玻璃，主体部221和边沿部223一体成型，主体部221和边沿部223具有较高的透光率。在一实施例中，主体部221大致呈矩形块状，边沿部223位于矩形的宽度方向的两侧，即边沿部223与矩形的两条长边连接。主体部221具有朝向后壳100的第一表面2211和背向后壳100的第二表面2213。边沿部223向第一表面2211的一侧弯曲以凸出于第一表面2211上，且边沿部223与第一表面2211形成容置槽300，显示屏210至少部分收容于容置槽300内，且显示屏210贴合于第一表面2211上，边沿部223与中框110连接。
进一步，参考图4，在一实施例中，主体部221的朝向显示屏210的一侧开设有沉槽2215，第一表面2211为沉槽2215的底壁，显示屏210至少部分收容于沉槽2215内。具体地，在一实施例中，沉槽2215的形状与显示屏210的形状匹配，即沉槽2215的长度和宽度分别与显示屏210的长度与宽度对应相等，显示屏210可以嵌设于沉槽2215内，显示屏210与沉槽2215的底壁贴合。进一步，在一实施例中，作垂直于移动终端10的厚度方向的平面，并以该平面作为主平面，显示屏210在主平面上的正投影与沉槽2215在主平面上的正投影重合，上述设置有利于显示屏210与沉槽2215的高精度配合。 通过设置沉槽2215，并将显示屏210嵌设于沉槽2215内，有利于显示屏210与盖板220的组装，且有利于显示屏210与盖板220的对中，从而可以提升装配的精度和效率。
可以理解的是，显示屏210与沉槽2215的底壁之间可以设置点胶层(图未标)，点胶层位于显示屏210的外周。进一步，点胶层位于显示屏210的非显示区域。利用点胶层，可以实现显示屏210与盖板220的牢固贴合。可以理解的是，沉槽2215的宽度也可以略大于显示屏210的宽度，沉槽2215的长度可以略大于显示屏210的长度。例如，沉槽2215的宽度与显示屏210的宽度的差值与显示屏210的宽度的比值可以小于2％，沉槽2215的长度与显示屏210的长度的差值与显示屏210的长度的比值可以小于2％，这种加工误差也应视为显示屏210在主平面上的正投影与沉槽2215在主平面上的正投影重合的情况，以使沉槽2215能够满足加工误差的要求，并有利于显示屏210与盖板220的对中设置。
在一实施例中，第一表面2211为平面，显示屏210为刚性屏，刚性屏难以弯曲，显示屏210贴合于第一表面2211上。由于主体部221的第一表面2211为平面，显示屏210就可以采用成本相对较低的刚性屏例如LCD(Liquid Crystal Display，液晶显示)屏，无需使用成本较高的柔性显示屏即可使移动终端10获得较佳外观，并降低移动终端10的成本。利用第一表面2211的平面与显示屏210贴合，还可避免显示屏210与盖板220的贴合面产生弯曲应力，有利于显示屏210与盖板220的牢固贴合。这种结构，可避免采用柔性屏弯曲贴合于盖板220上，使柔性屏的表面产生弯曲应力，导致显示屏210与盖板220的贴合不牢固。
在图4所示实施例中，第二表面2213为平面，第二表面2213与第一表面2211平行。在其他实施方式中，第二表面2213也可以为曲面例如弧面，第二表面2213采用弧面时，可以使得移动终端10具有曲面显示效果，并可美化移动终端10的外观。在一实施例中，作垂直于移动终端10的长度方向的平面，边沿部223向显示屏210的一侧弯曲的形状大致呈弧形，即边沿部 223的朝向移动终端10内部的表面和朝向移动终端10外部的表面均为弧面状。在边沿部223设于显示屏210的侧面并与后壳100的中框110连接后，一方面使得移动终端10具有较佳的外观；另一方面，利用边沿部223的弯曲结构对光线的折射和反射，既能使得中框110的宽度在视觉上显得较窄，还能够使得显示屏210的外周的非显示结构在视觉上呈现的黑边的宽度较窄。
进一步，在一实施例中，边沿部223在主平面上的正投影的宽度与显示屏210在主平面上的正投影的宽度的比值小于0.03，边沿部223距第二表面2213的最大高度与主体部221的最大厚度的比值小于6。具体地，参考图3，在一实施例中，盖板220的第二表面2213为平面，第二表面2213可以作为主平面，边沿部223在第二表面2213上的正投影的宽度与显示屏210在第二表面2213上的正投影的宽度的比值小于0.03。例如，在图3所示实施例中，显示屏210在第二表面2213上的正投影的宽度为D，边沿部223在第二表面2213上的正投影的宽度为d，则(d/D)<0.03。在图3所示实施例中，边沿部223距第二表面2213的最大高度为H，主体部221的最大厚度为h，则(H/h)<6。上述结构，边沿部223的弯曲弧度较大，边沿部223的内表面与显示屏210的朝向边沿部223的侧面形成的缝隙较窄，这种结构使得外圈的宽度在视觉上显得较窄，并使得显示屏210的外周的非显示结构在视觉上呈现的黑边的宽度较窄。
在一实施例中，边沿部223向显示屏210的弯曲结构通过热压成型工艺获得。在其他实施方式中，边沿部223向显示屏210的弯曲结构可以通过CNC(Computer Numerical Control，数控机床)加工的方式获得。在一实施例中，边沿部223的内表面与显示屏210的朝向边沿部223的侧面形成的缝隙中可以设置粘接层(图未示)，粘接层可以为透明的粘胶。通过设置粘接层，可以使显示屏210和盖板220连接牢固。在一实施例中，显示屏210在主平面上的正投影位于第二表面2213在主平面上的正投影内。上述设置，第二表面2213完全覆盖于显示屏210的上方，当显示屏210显示信息时，利用第二表面2213的结构的一致性，显示屏210的光线透过第二表面2213，可以呈现 一致的显示效果，可防止主体部221与边沿部223的连接部位因曲率变化造成显示效果不一致，对用户体验产生不利的影响。
上述移动终端10及其显示屏组件200，显示屏组件200的盖板220包括主体部221和边沿部223，边沿部223向后壳100的一侧弯曲并可连接于后壳100上，显示屏210贴合于主体部221的第一表面2211上，由于边沿部223向后壳100的一侧凸出于第一表面2211上形成容置槽300，容置槽300为显示屏210的提供了安装空间，因此可以减小后壳100在移动终端10的厚度方向上的尺寸，以使移动终端10的外观更加简洁。由于主体部221的朝向显示屏210的一侧开设有沉槽2215，显示屏210可以嵌设于沉槽2215内，从而有利于显示屏210与盖板220的组装，且有利于显示屏210与盖板220的对中，从而可以提升装配的精度和效率。
参考图5和图6，在一实施例中，中框110可以包括本体111和第一凸台113，本体111和第一凸台113一体成型，显示屏210的远离盖板220的一侧抵接于第一凸台113上。在一实施例中，第一凸台113的宽度与显示屏210的宽度匹配，显示屏210设置于第一凸台113上，显示屏210与第一凸台113之间可以设置粘胶层(图未示)，以使显示屏210与中框110连接。第一凸台113有利于显示屏210在中框110上的定位，并有利于显示屏210与中框110的连接。在一实施例中，第一凸台113在本体111上连续分布，第一凸台113位于显示屏210的外周，且第一凸台113在主平面上的正投影呈圆角矩形。当第一凸台113与显示屏210之间设置粘胶层时，这种结构有利于显示屏210与中框110的牢固连接，并有利于显示屏210与中框110的密封连接，以提升移动终端10的防水性能。在其他实施方式中，第一凸台113也可以是不连续的，即第一凸台113在本体111上可以间隔分布，第一凸台113同样有利于显示屏210与中框110的连接。
在一实施例中，中框110还可以包括第二凸台115，第二凸台115与本体111一体成型。第二凸台115具有抵持面116，抵持面116为平面，抵持面116与主平面的夹角小于45度，边沿部223抵接于抵持面116上。具体地，在图 6所示实施例中，第二凸台115向靠近盖板220的一侧凸出于第一凸台113上，抵持面116由移动终端10的外部向内部倾斜。在图6所示实施例中，移动终端10呈水平放置，左侧的抵持面116沿顺时针方向旋转一个小于45度的角度即可与水平面重合，右侧的抵持面116沿逆时针方向旋转一个小于45度的角度即可与水平面重合。在一实施例中，抵持面116上可以设置粘胶层，边沿部223通过粘胶层与中框110连接。上述抵持面116的结构，在盖板220与中框110连接后，抵持面116对盖板220的支撑力具有沿盖板220的宽度方向分布并指向移动终端10内部的分力，该分力使得主体部221两侧的边沿部223有向内靠近的趋势，因此能够防止主体部221两侧的边沿部223外张，进而能够保证盖板220与中框110的连接的可靠性。
在一实施例中，第二凸台115在本体111上连续分布，第二凸台115位于第一凸台113的外周，且第二凸台115在主平面上的正投影呈圆角矩形。当第二凸台115与盖板220之间设置粘胶层时，这种结构有利于盖板220与中框110的牢固连接，并有利于盖板220与中框110的密封连接，以提升移动终端10的防水性能。在其他实施方式中，第二凸台115也可以是不连续的，即第二凸台115在本体111上间隔分布，第二凸台115同样有利于盖板220与中框110的连接。
在一实施例中，中框110还可以包括第三凸台117，第三凸台117与本体111一体成型。第三凸台117位于边沿部223的远离显示屏210的一侧，且边沿部223与第三凸台117抵接。具体地，在图6所示实施例中，第三凸台117向靠近第二表面2213的一侧外凸于第二凸台115上，第三凸台117与边沿部223抵接并对边沿部223的边缘形成半包结构，以利于盖板220在后壳100上的定位，并能够对盖板220起到保护作用，防止盖板220的边缘因意外碰撞而造成损伤。在一实施例中，第三凸台117在本体111上连续分布，第三凸台117位于第二凸台115的外周，且第三凸台117在主平面上的正投影呈圆角矩形。第三凸台117有利于盖板220与中框110的牢固连接。在其他实施方式中，第三凸台117也可以是不连续的，即第三凸台117在本体111上 间隔分布，第三凸台117同样有利于盖板220与中框110的连接。在一实施例中，中框110的外侧沿移动终端10厚度方向上延伸的表面为弧形面，该弧形面的弯曲弧度略大于边沿部223的弯曲弧度，使得移动终端10的侧面为曲面结构，有利于美化移动终端10的外观，并有利于提升移动终端10的外观的整体性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
