技术领域
本申请涉及电子产品结构领域，具体而言，涉及显示模组及电子设备。
背景技术
一些电子设备，如手机、笔记本电脑等，具有屏幕。以手机为例，在组装时需要将屏幕粘结在前壳上。
然而，现有技术中，电子设备的前壳和屏幕之间的粘接结构存在粘接可靠性较差的问题。
发明内容
本申请提供显示模组及电子设备，以解决现有技术中前壳和屏幕粘接可靠性较差的问题。
第一方面，本申请实施例提供一种显示模组，包括前壳、显示屏和盖板，前壳包括底板和侧板。显示屏叠合连接于盖板的一侧端面；盖板包括与显示屏重叠的叠合部分和延伸于叠合部分之外的外延部分；外延部分自与显示屏连接处向外延伸一侧的表面构成第一胶合面，显示屏朝向侧板的外侧面构成第二胶合面；
侧板远离底板的一端设置为支撑连接端；支撑连接端具有依次连接的内表面、坡面、顶端面和外表面；内表面和外表面相对设置；
内表面和第二胶合面间隔相对，以限定第一间隙；
顶端面和第一胶合面间隔相对，以限定第二间隙；
坡面与第一胶合面和第二胶合面分别倾斜地间隔相对，以限定第三间隙；
第一间隙和第二间隙分别连通第三间隙，以使第一间隙、第三间隙和第二间隙三者组成胶合空间；胶合空间内填充胶合材料，形成胶合体。
本方案中的显示模组通过在侧板的支撑连接端设置坡面，其和顶端面、内表面共同作为粘胶面与显示屏的第二胶合面和盖板的第一胶合面之间的粘接，有效粘接宽度和粘接面积大、粘接可靠性胶合，且能够对显示屏提供较好的防护。
其中，第一间隙和第三间隙的一部分内的胶合体能够将显示屏牢靠地粘接于支撑连接端的内表面，使显示屏不容易沿垂直于其板面的方向与前壳分离；第二间隙和第三间隙的一部分内的胶合体能够可靠地将盖板粘接于支撑连接端的顶端面和坡面，使盖板不容易沿平行于其板面的方向与前壳分离。
并且，通过设置斜坡，在显示屏和盖板交角处能够容纳更多的胶合材料，即形成在第三间隙的胶合材料能够可能地连接第一间隙和第二间隙内的胶合材料，避免直接直角转折的胶合体在转折处受力外力或内应力断裂，确保胶合体的一体形式。
本方案通过结构设置，得到大致呈转折处内侧加强的L形胶合体，具有较高的粘接宽度、粘接面积和粘接可靠性。
在一种可能的实现方式中，坡面为平面或弧面。
本实现方式中，坡面可以是平面，平面加工较为简单，且在设置坡面增加了粘接面积的基础上，坡面设置为平面可以满足一些场景。坡面也可设置为弧面，例如坡面设置为向靠近底板一侧凹入的凹坡面、向远离底板一侧凸出的凸坡面等。坡面设置为弧面能够进一步提高 粘接面积。
在一种可能的实现方式中，坡面上设置有沿坡向分布的锯齿。
通过设置锯齿，能够进一步提高粘接面积和粘接强度。
在一种可能的实现方式中，盖板的外周面和第一胶合面的交接处设置为倾斜面，倾斜面从内向外逐渐远离支撑连接端，以形成用于多余胶合材料挤出的排胶口。
本实现方式中，通过设置逐渐远离支撑连接端的倾斜面，从而和支撑连接端之间形成排胶口，利于多余胶合材料的挤出。
在一种可能的实现方式中，外表面和盖板的外周面共面。
通过使侧板的外表面和盖板的外周面共面，即去掉了现有前壳外侧裙边，使得沿朝向盖板的方向的视角范围内仅盖板可见，而前壳被完全遮挡，具有较好的沉浸感。
在一种可能的实现方式中，侧板垂直于底板。
在其他实现方式中，侧板还可以和底板呈一定角度。例如，侧板和底板之间的夹角还可以略大于90度，如此，能够使前壳更好地被盖板遮挡。
在一种可能的实现方式中，侧板的外表面自底板延伸的高度大于内表面自底板延伸的高度，顶端面连接外表面朝向内表面一侧的顶端，坡面自顶端面朝向内表面倾斜延伸。
在一种可能的实现方式中，前壳的宽度为0.3-0.5mm，如前壳宽度设置为0.4mm。其中，顶端面的宽度占前壳宽度的比例小于1/4。
通过前述设置，本身能够实现前壳与盖板、显示屏之间的可靠粘接，前壳宽度可以设置得较小。并且，通过设置顶端面占用的宽度比例，能够使坡面具有足够大的宽向占比，从而能够得到更多的粘接面积。
本申请实施例的第一方面还提供另一种显示模组，包括前壳、显示屏和盖板，前壳包括底板和侧板。显示屏叠合连接于盖板的一侧端面；盖板包括与显示屏重叠的叠合部分和延伸于叠合部分之外的外延部分；外延部分自与显示屏连接处向外延伸一侧的表面构成第一胶合面，显示屏朝向侧板的外侧面构成第二胶合面。侧板远离底板的一端设置为支撑连接端；支撑连接端具有依次连接的内表面、顶端面和外表面；内表面和外表面相对设置。顶端面呈锯齿状。内表面和第二胶合面间隔相对，以限定第四间隙。顶端面和第一胶合面间隔相对，以限定第五间隙。第四间隙和第五间隙相互连通组成胶合空间；胶合空间内填充胶合材料，形成胶合体。
本方案中的显示模组通过在侧板的支撑连接端设置锯齿状的顶端面，其和内表面共同作为粘胶面与显示屏的第二胶合面和盖板的第一胶合面之间的粘接，有效粘接宽度和粘接面积大、粘接可靠性胶合，且能够对显示屏提供较好的防护。
第二方面，本申请实施例还提供一种电子设备，包括前述的显示模组。
本实施例中的电子设备的显示模组同样具有有效粘接宽度和粘接面积大、粘接可靠性胶合的有益效果。

本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施方式及实施方式中的特征可以相互组合。
参见图1-图3，本申请一实施例提供一种显示模组100，可作为电子设备的一个组件装配在电子设备中，用于画面呈现。
该处所说的电子设备可以是移动终端(例如，手机、平板电脑、笔记本电脑等)、可穿戴设备(例如，智能手表、智能眼镜等)、显示设备(例如，电视机、智能屏等)、摄像机、游戏机等，也可以是其他种类的具有显示模组的电子设备。
继续参见图1-图3，本申请实施例中的显示模组100包括前壳110、显示屏120和盖板130。其中，前壳110包括底板111和侧板112。显示屏120叠合连接于盖板130的一侧端面，两者叠合面之间可以相互胶合。盖板130包括与显示屏120重叠的叠合部分131和延伸于叠合部分131之外的外延部分132。外延部分132与显示屏120连接处向外延伸一侧的表面构成第 一胶合面P1，显示屏120朝向侧板112的外侧面构成第二胶合面P2。
侧板112远离底板111的一端设置为支撑连接端112a，支撑连接端112a具有依次连接的内表面P3、坡面P4、顶端面P5和外表面P6，内表面P3和外表面P6相对设置。内表面P3和第二胶合面P2间隔相对，以限定第一间隙Q1。顶端面P5和第一胶合面P1间隔相对，以限定第二间隙Q2。坡面P4与第一胶合面P1和第二胶合面P2分别倾斜地间隔相对，以限定第三间隙Q3。第一间隙Q1和第二间隙Q2分别连通第三间隙Q3，以使第一间隙Q1、第三间隙Q3和第二间隙Q2三者组成胶合空间Q9。胶合空间Q9内填充胶合材料，形成胶合体140。胶合体140用于实现显示屏120和盖板130与前壳110之间的粘接。
本方案中的显示模组100通过在侧板112的支撑连接端112a设置坡面P4，其和顶端面P5、内表面P3共同作为粘胶面与显示屏120的第二胶合面P2和盖板130的第一胶合面P1之间粘接，有效粘接宽度和粘接面积大、粘接可靠性高，且能够对显示屏120提供较好的防护。同时，本实施例中，充分利用盖板超过显示屏的外延部分132进行粘接，粘接可靠性和对显示屏120的防护性均较好。
其中，第一间隙Q1和第三间隙Q3的一部分内的胶合体140能够将显示屏120牢靠地粘接于支撑连接端112a的内表面P3，使显示屏120不容易沿垂直于其板面的方向与前壳110分离；第二间隙Q2和第三间隙Q3的一部分内的胶合体140能够可靠地将盖板130粘接于支撑连接端112a的顶端面P5和坡面P4，使盖板130不容易沿平行于其板面的方向与前壳110分离。
并且，通过设置坡面P4，在显示屏120和盖板130交角处能够容纳更多的胶合材料，即形成在第三间隙Q3的胶合材料能够可靠地连接第一间隙Q1和第二间隙Q2内的胶合材料，避免直接直角转折的胶合体140在转折处受外力或内应力断裂，确保胶合体140的一体形式。
本方案通过结构设置，得到大致呈转折处内侧加强的L形胶合体140，具有较高的粘接宽度、粘接面积和粘接可靠性。
配合参见图4和图5，本实施例中的显示模组100在胶合时，可采用点胶141的方式实现。胶合时，将点胶141滴在坡面P4上，然后使显示屏120和盖板130两者对准前壳110下压，居中组装。在下压的过程中，点胶141在挤压作用下一部分填充第三间隙Q3、一部分沿坡面P4进入第一间隙Q1、一部分受挤压进入第二间隙Q2并从第二间隙Q2向外挤出多余的点胶141。擦除多余的点胶141后，剩余的点胶141便形成前述的胶合体140，见于图1。在擦胶后，还可对胶合体140的外观进行抛光或缺陷修复等处理。即，本申请实施例中设置坡面P4还具有引导点胶141填充的效果，相较现有在水平台阶面上施胶的方式，对于胶合材料的填充更有利。本方案中采用点胶工艺，较之背胶，其外观效果更好、密封防水等级较高、粘结强度较高。
本实施例中，胶合体140为填充在前壳110与显示屏120和盖板130的缝隙一周的封闭结构，其特殊的截面形状能够很好地实现连接处的密封。
本实施例中，侧板112的外表面P6自底板111延伸的高度大于内表面P3自底板111延伸的高度，顶端面P5连接外表面P6朝向内表面P3一侧的顶端，坡面P4自顶端面P5朝向内表面P3倾斜延伸。坡面P4的坡角可以根据需要设定。例如，设置坡角在30-60度之间，优选45度。
在一种可能的实施方式中，支撑连接端112a的外表面P6和盖板130的外周面P7共面。通过使侧板112的外表面P6和盖板130的外周面P7共面，即去掉了现有技术中前壳110外 侧裙边，使得沿朝向盖板130的方向的视角范围内仅盖板130可见，而前壳110被完全遮挡，具有较好的沉浸感。如图1所示，黑边的宽度L1大致为从显示屏120的侧面(第一胶合面P1)到外表面P6或外周面P7的距离(对于显示屏120外周存在非显示区域的情形，黑边的宽度L1还要加上显示屏120的非显示区域的宽度)。当然，在其他实施方式中，外表面P6也可以小部分位于盖板130的外周面P7之外，只需黑边在能接受的范围之内。
本实施例中，可选地，侧板112垂直于底板111，即侧板112从底板111的边缘沿垂直于底板111的方向延伸而成。在实际制造过程中，侧板112和底板111可以通过模具一体成型。
在其他实现方式中，侧板112还可以和底板111呈一定角度。例如，侧板112和底板111之间的夹角还可以略大于90度，如此，能够使前壳110更好地被盖板130遮挡。
本实施例中，可选地，盖板130的外周面P7和第一胶合面P1的交接处设置为倾斜面P8，倾斜面P8从内向外逐渐远离支撑连接端112a，以形成用于多余胶合材料挤出的开口较大的排胶口K1。可选地，倾斜面P8分别对应顶端面P5和部分的坡面P4。本实现方式中，通过设置逐渐远离支撑连接端112a的倾斜面P8，从而和支撑连接端112a之间形成排胶口K1，利于多余胶合材料的挤出。
在一种可能的实现方式中，前壳110的宽度为0.3-0.5mm，如设置为0.4mm左右。其中，顶端面P5的宽度占前壳110宽度的比例小于1/4。通过前述坡面P4的设置，本身能够实现前壳110与盖板130、显示屏120之间的可靠粘接，前壳110宽度可以设置得较小。并且，通过设置顶端面P5占用的宽度比例，能够使坡面P4具有足够大的宽向占比，从而能够得到更多的粘接面积。较之现有技术设置水平台阶面来实现粘接的方式，本方案设置坡面P4的方式能够将台阶宽从1.3mm降低至0.4mm左右，对应的黑边减小约0.9mm。
图1-图5中示出的实施方式中，坡面P4为平面。坡面P4设置为平面，加工较为简单，且在设置坡面P4增加了粘接面积的基础上，坡面P4设置为平面可以满足一些使用场景。
在其他实方式中，坡面P4还可以设置为弧面。例如参见图6，坡面P4设置为向靠近底板111一侧凹入的凹坡面P4；参见图7，坡面P4设置为向远离底板111一侧凸出的凸坡面P4等。坡面P4设置为弧面能够进一步提高粘接面积。
参见图8，不管坡面P4为平面还是弧面，均可以在坡面P4上设置有沿坡向分布的锯齿113。通过设置锯齿113，能够进一步提高粘接面积和粘接强度。可以理解的，锯齿113可为连续的凹凸结构亦可为间隔设置的凹凸结构。为更好的粘接，本实施例中，锯齿113为连续的凹凸结构。
配合参见图9和图10，本申请实施例还提供一种电子设备010，包括基体200和前述的显示模组100。显示模组100可以连接在电子设备010的基体200的正面。本实施例中的电子设备010的显示模组100同样具有有效粘接宽度和粘接面积大、粘接可靠的有益效果。
以电子设备010为手机为例，显示模组100的前壳110是手机的中框，显示屏120可以是液晶显示屏，盖板130上可设置触摸感应单元，使其成为触摸屏结构。基体200包括后盖210等结构，显示模组100以其前壳110固定连接在基体200的正面，并和后盖210连接。基体200优选地隐藏在显示模组100后面，使得在朝向显示模组100的方向上，仅盖板130可见(部分侧向凸出的按键除外)。
配合参见图11和图12，本申请实施例还提供另一种显示模组100a，包括前壳110、显示屏120和盖板130，前壳110包括底板111和侧板112。显示屏120叠合连接于盖板130的一侧端面；盖板130包括与显示屏120重叠的叠合部分131和延伸于叠合部分131之外的外延 部分132；外延部分132自与显示屏120连接处向外延伸一侧的表面构成第一胶合面P1，显示屏120朝向侧板112的外侧面构成第二胶合面P2。侧板112远离底板111的一端设置为支撑连接端112a；支撑连接端112a具有依次连接的内表面P3、顶端面P5和外表面P6；内表面P3和外表面P6相对设置。顶端面P5呈锯齿状。内表面P3和第二胶合面P2间隔相对，以限定第四间隙Q4。顶端面P5和第一胶合面P1间隔相对，以限定第五间隙Q5。第四间隙Q4和第五间隙Q5相互连通组成胶合空间Q9；胶合空间Q9内填充胶合材料，形成胶合体140。
图11和图12示出的显示模组100a和前述图1-图5示出的显示模组100的不同之处在于，支撑连接端112a未设置前述的坡面P4，而是仅仅通过将顶端面P5设置为锯齿状，来增大粘接面积，提高粘接强度。
本方案中的显示模组100a通过在侧板112的支撑连接端112a设置锯齿状的顶端面P5，其和内表面P3共同作为粘胶面与显示屏120的第二胶合面P2和盖板130的第一胶合面P1之间的粘接，有效粘接宽度和粘接面积大、粘接可靠性胶合，且能够对显示屏120提供较好的防护。
以上实施方式仅用以说明本申请的技术方案而非限制，尽管参照以上较佳实施方式对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或等同替换都不应脱离本申请技术方案的精神和范围。
