为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
请参照图1至图5，本实施例提供一种电视机，包括具有显示面板10的显示模组、与显示模组电连接的电源和控制电路。电视机还包括用于固定显示模组的模组支架20，以及用于容置电源、控制电路并固定模组支架20的装置支架30。需要说明的是，本实施例中的模组支架20和装置支架30也可以适用于广告机等设备，尤其适用于户外使用。
装置支架30包括上下设置的装置上壳31与装置下壳32，装置上壳31与装置下壳32围合形成一装置容腔33，装置上壳31的下端部套设于装置下壳32的上端部的外侧或插设于装置下壳32的上端部的内侧，装置上壳31的下端部和装置下壳32 的上端部通过发泡胶40水密连接。装置上壳31的下端部和装置下壳32的上端部之间留有间隙，发泡胶40填充于该间隙从而实现装置上壳31的下端部与装置下壳32的上端部的水密连接。本领域人员可以根据装置上壳31的下端部和装置下壳32的上端部相对面积尺寸设置发泡胶40的填充量，只要实现装置上壳31的下端部和装置下壳32的上端部的水密连接即可。
图示实施例中，装置上壳31的下端部套设于装置下壳32的上端部的内侧。
装配过程中，点胶设备在装置上壳31的下端部外侧表面或装置下壳32的上端部的内侧表面喷涂发泡胶40，而后将装置上壳31向下和装置下壳32盖合，使装置上壳31的下端部和装置下壳32的上端部相对，此时，发泡胶40同时连接装置上壳31和装置下壳32。发泡胶40固化而使得装置上壳31和装置下壳32水密连接。
由于发泡胶40在喷涂时为泡沫状并能够根据周侧环境变化其外形，或者说能够填充两个结构之间的空隙，使得固化后两个结构之间实现无缝连接。使用发泡胶40替代橡胶圈，由于发泡胶40的特性，无需考虑两个结构在装配过程中产生的变形对密封性的影响。也就说，无论装配过程中，产生怎样的形变，均能确保两个结构的无缝连接，从而确保两个结构之间的水密性。因此，本实施例中，无论装置上壳31和装置下壳32是否发生形变，发泡胶40均自动填充于装置上壳31和装置下壳32之间的间隙，从而在发泡胶40固化后实现水密连接。
发泡胶40填充于装置上壳31和装置下壳32之间，而呈环状。本实施例中，装置上壳31水平投影为矩形，对应的，发泡胶40水平投影呈矩形环状。
装置上壳31的下端部具有向内凹陷并延伸至其下表面且呈环状的凹槽，装置下壳32的上端部套设于凹槽。
首先，凹槽的设置能够提高结构弹性模数，增加结构强度。其次，凹槽的设置，能够对装置上壳31和装置下壳32的装配提供定位，具体的，凹槽的上槽壁限制装置下壳32向上移动，从而设定了装配的位置。此外，装置下壳32的上端部位于装置上壳31的外侧，凹槽的设置，使得上端部的外表面能够与装置上壳31的外表面平齐，美化外观。
本实施例中，请参照图4，装置支架30还包括用于连接装置上壳31的下端部和装置下壳32的上端部的紧固件。本实施例中，紧固件为螺丝。附图未示出紧固 件的结构，示出了与紧固件配合连接的连接孔。连接孔开设于凹槽处。连接孔有多个并间隔设置。在一实施例中，开设于装置下壳32的上端部的连接孔为沉头孔2111以实现隐藏螺丝的效果。装置上壳31和装置下壳32之间由螺丝实现稳固连接。
本实施例中，装置上壳31下端部为折边板，包括垂直设置的第一边板和第二边板，第一边板向内凹陷形成凹槽。第一边板与装置下壳32的上端部螺接，第二边板与装置下壳32留有填充发泡胶40的间隙。在其它实施例中，发泡胶40也可以填充于凹槽处或同时填充凹槽和该间隙。
请参照图5，装置上壳31的下端部开设有环状的导胶槽311。图示实施例中，导胶槽311截面为圆弧形且重心位于导胶槽311外。该设置下，导胶槽311入口处为截面最宽位置，而后向内减缩，从而引导发泡胶40向槽底聚集。导胶槽311的设置，增加了发泡胶40的容积，更重要的，导胶槽311的设置，引导发泡胶40优先聚集于导胶槽311内，有利于确保导胶槽311处的水密连接。此外，装置上壳31和装置下壳32之间的小形变下，导胶槽311内的发泡胶40也能及时补充到形变的位置。
请再次参照图5，装置下壳32的上端部在导胶槽311的位置相应开设有贯通设置的注胶孔321。点胶设备喷涂发泡胶40，而后对装置上壳31和装置下壳32进行装配。在装配过程中，如果发现装置上壳31和装置下壳32之间的发泡胶40胶量不够，可以通过注胶孔321向内注入发泡胶40。本领域人员可以理解，该注胶孔321是为了补充少量的发泡胶40时使用，因此注胶孔321的孔径较小。此外，孔径较小也有利于降低发泡胶40通过注入孔向外流出的情况。
本实施例中，装置上壳31和装置下壳32连接形成开口朝上的装置容腔33。
模组支架20置于装置容腔33，且其上表面通过发泡胶40与装置容腔33的上腔壁水密连接并封闭装置容腔33的开口。
装配过程中，将模组支架20置于装置下壳32，而后点胶设备在模组支架20上表面或装置上壳31的下表面喷涂发泡胶40，在装置上壳31的下端部外侧表面或装置下壳32的上端部的内侧表面喷涂发泡胶40，而后将装置上壳31套设在装置下壳32上，对装置上壳31和装置下壳32进行螺接，与此同时，发泡胶40慢慢固化 ，而使装置上壳31和模组支架20水密连接、装置上壳31和装置下壳32水密连接。基于发泡胶40的特性，无论装置上壳31和模组上壳21是否发生形变，装置上壳31和模组支架20、装置上壳31和装置下壳32均能够实现水密连接。模组支架20、装置上壳31和装置下壳32之间水密连接，使得装置容腔33成为水密舱室，以保护位于装置容腔33内的电路板等电子器件免受水气的影响。
请参照图2和图4，模组支架20包括模组上壳21和模组下壳22，模组上壳21和模组下壳22扣合连接而形成模组容腔23，模组上壳21包括环状的封板212和连接封板212外侧表面并向下延伸的竖板211，模组下壳22包括环状的底板和连接底板周侧并向上延伸的壁板，模组下壳22还包括设于壁板的放置台222，竖板211套于壁板外侧，放置台222与封板212围合形成容置显示模组的显示面板10的限位槽，显示模组的显示面板10置于限位槽且其上表面与封板212下表面之间填充发泡胶40而实现水密连接。
装配过程中，将显示面板10置于限位槽，点胶设备在显示面板10上表面喷涂发泡胶40或者在限位槽的上槽壁喷涂发泡胶40，而后将模组上壳21扣合在模组下壳22上使得显示面板10和模组上壳21之间的空隙被发泡胶40填充。发泡胶40固化而使得显示面板10和模组上壳21水密连接，从而避免水气经由显示面板10和模组上壳21之间的间隙进入模组支架20的内部。
放置台222的设置用于放置显示面板10。图示实施例中，放置台222距离模组容腔23的腔底还有一定的空间距离，以容置显示模组除显示面板10外的其它电子元件。显示面板10放置于放置台222上，显示面板10的上表面靠近周侧处通过发泡胶40与模组上壳21水密连接，使得水气不能经由显示面板10和模组上壳21的连接处进入到模组容腔23内，以保护模组容腔23内的电子元器件。
本实施例中，模组上壳21和模组下壳22之间通过螺丝连接。具体的，请参照图4，竖板211开设有内外贯通的沉头孔2111，壁板在沉头孔2111处开设有贯通设置的螺接孔221，模组支架20还包括穿过沉头孔2111与螺接孔221螺接的螺丝(未图示)。沉头孔2111有多个，并间隔设置于竖板211。螺接孔221和螺丝均有多个并均与沉头孔2111对应设置。沉头孔2111的设置，使得螺丝的螺帽隐藏置于沉头孔2111内而不会突出于竖板211表面。从而避免对装置上壳31的抵触。竖 板211和模组下壳22之间通过多个螺丝连接，实现模组上壳21和模组下壳22之间的稳固连接。
本实施例中，装置上壳31与模组支架20螺接。
对装置支架30和模组支架20装配过程进一步说明如下，先在喷涂工位进行发泡胶40的涂覆，本实施例中，涉及三个位置的发泡胶40的喷涂，发泡胶40在高温环境下喷涂，而后转移至装配工位，对各结构进行组装，与此同时，发泡胶40自然冷却。发泡胶40冷却固化需要较长的时间(20分钟左右)，而装配所需的时间较短，因此在喷涂发泡胶40之后进行装配不会对发泡胶40的固化连接质量产生影响。而采用先喷涂发泡胶40再组装，操作也更为便利：如果先组装再喷涂，则由于各结构之间的缝隙较小而难以将发泡胶40填充至各结构支架之间的间隙。因此，采用先喷涂发泡胶40再组装，操作更为便利。
请参照图4和图5，装置下壳32和模组下壳22之间设有连接件，连接件50包括连接装置下壳32的第一横板、连接模组下壳22的第二横板和连接第一横板和连接第二横板的连接板，连接件的设置，使得模组下壳22能够经连接件而由装置下壳32所承托，从而有利于提高模组支架20和装置支架30形成的框架的结构强度。
连接件50与模组下壳22螺接，连接件50与装置下壳32螺接。
本实施例中，连接件50有多个，并绕模组下壳22的周沿设置。图示实施例中，模组下壳22的下表面呈矩形，连接件有四个并设于该矩形的四个边侧。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本发明的保护范围之内。
