一种摄像模组及电子设备
本申请要求于2016年7月18日提交中国专利局、申请号为201610570578.X、发明名称为“一种摄像模组及电子设备”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
本申请涉及成像技术领域，更具体地说，涉及一种摄像模组及电子设备。
背景技术
电子设备的智能化是目前电子设备的发展趋势，摄像模组作为电子设备的重要信息获取装置成为其智能化道路上的必要装置之一。因此，随着电子设备智能化的不断发展，对于摄像模组的要求也越来越高，越来越多的电子设备要求应用于其上的摄像模组具有防雾功能。
以智能冰箱为例，摄像模组设置于智能冰箱内部，用于通过网络或其他传输方式向外界传送智能冰箱内部的物品信息。都是由于智能冰箱内部的高湿低温环境，设置于智能冰箱内部的摄像模组表面很容易在智能冰箱开关门的过程中凝结水雾，影响摄像模组自身的成像效果，难以准确传递智能冰箱内部的物品信息，从而难以满足智能冰箱的要求。并且传统的摄像模组的体积较大，会使得智能冰箱的箱体结构的制作难度增加。
因此，亟需一种具有防雾功能，且体积较小的摄像模组。
发明内容
为解决上述技术问题，本发明提供了一种摄像模组及电子设备，以实现具有防雾功能且减少摄像模组自身体积的问题。
为实现上述技术目的，本发明实施例提供了如下技术方案：
一种摄像模组，包括：基板、底座、镜头、感光芯片和盖板；其中，
所述底座设置于所述基板表面，远离所述基板一端具有台阶；
所述盖板固定于所述台阶的阶位表面，与所述底座和基板形成密封腔，且所述盖板表面具有防雾层或加热层，所述防雾层设置于所述盖板背离所述基板一侧表面，所述加热层设置于所述盖板朝向所述基板一侧表面；

优选的，所述加热层包括：
设置于所述盖板朝向所述底座一侧表面的ITO膜层；
设置于所述ITO膜层朝向所述底座一侧表面的加热片或加热丝。
优选的，所述基板为印制电路板或柔性电路板。
优选的，所述镜头为塑胶镜头或玻璃镜头或玻塑混合镜头。
优选的，所述盖板通过粘贴胶固定于所述台阶的阶位表面。
优选的，所述粘贴胶为自然固化胶。
优选的，所述盖板为玻璃盖板或透明薄膜盖板。
一种电子设备，包括至少一个如上述任一实施例所述的摄像模组。
从上述技术方案可以看出，本发明实施例提供了一种摄像模组及电子设备，其中，所述摄像模组采用底座配合基板和盖板形成密封腔，所述密封腔既起到了让镜头和感光芯片处于封闭暗室的作用，还起到了容纳盖板的作用；因此不需要增加独立的模组外壳容纳所述盖板，从而减小了摄像模组的体积；因此所述摄像模组不需要增加独立的模组外壳容纳所述盖板，从而减小了所述摄像模组的体积；并且所述镜头与感光芯片均设置于所述密封腔中，不会受到外界冷热气流交互的影响。
进一步的，所述盖板表面具有防雾层或加热层，以避免当所述摄像模组所处环境的湿度较大时在所述盖板表面形成水雾或可通过自身加热使雾气快速散去，从而避免影响所述摄像模组成像效果的情况出现。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施 例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为本申请的一个实施例提供的一种摄像模组的结构示意图。
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，所描述的实施例仅仅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做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。
本申请实施例提供了一种摄像模组，如图1所示，包括：基板400、底座300、镜头200、感光芯片和盖板100；其中，
所述底座300设置于所述基板400表面，远离所述基板400一端具有台阶；
所述盖板100固定于所述台阶的阶位表面，与所述底座300和基板400形成密封腔，且所述盖板100表面具有防雾层或加热层(并未在附图1中示出)，所述防雾层设置于所述盖板100背离所述基板400一侧表面，所述加热层设置于所述盖板100朝向所述基板400一侧表面；
所述镜头200与感光芯片(并未在附图1中示出)设置于所述密封腔中。
一般情况下，所述感光芯片贴放于所述基板400表面，所述镜头200汇聚的光线成像于其表面。
在本申请的一个实施例中，所述底座300可以为筒状底座；但在本申请的其他实施例中，所述底座300还可以为方形底座，本申请对所述底座300的具体形状并不做限定，具体视实际情况而定。
需要说明的是，当所述摄像模组应用的环境的湿度或温差变化较大时，空气中的水分容易在所述盖板100背离所述底座300一侧表面凝结；当所述防雾层为水滴角较大的材料形成时，所述防雾层的亲水性较差，在所述防雾层表面凝结的水滴很容易滑落，避免对所述摄像模组的成像效果产生影响，起到防雾的 效果；当所述防雾层为表面活性剂一类的材料形成时，所述防雾层可以将在其表面凝结的水滴拉成一层厚度均一的水膜，这层水膜在所述摄像模组的成像过程中相当于一块透光膜，并不会影响所述摄像模组的成像效果，起到防雾的效果。所述加热层可以通过自身的加热功能使凝结在其表面的雾气快速散去，从而起到防雾效果，避免水滴影响摄像模组成像效果的情况出现。
以所述摄像模组在智能冰箱中的应用为例，由于所述智能冰箱内部的湿度较大且温度较低，当所述智能冰箱开关门时，外部较热的空气会进入所述智能冰箱内部，冷热空气的相遇使得空气中的水分极易凝结。而所述防雾层或加热层的存在使得所述摄像模组具有良好的防雾效果。
并且，所述底座300配合基板400和盖板100形成密封腔，避免设置于所述密封腔中的镜头200和感光芯片受到外界冷热气流交互的影响。
进一步的，所述摄像模组采用底座300配合基板400和盖板100形成密封腔，所述密封腔既起到了让镜头和感光芯片处于封闭暗室的作用，还起到了容纳盖板的作用；因此不需要增加独立的模组外壳对内部部件进行保护，从而减小了摄像模组的体积；因此所述摄像模组不需要增加独立的模组外壳对所述摄像模组内部部件进行保护，从而减小所述摄像模组的体积。
还需要说明的是，设置于所述盖板100朝向所述基板400一侧表面的加热层还可以起到防水、防氧化的作用。
在上述实施例的基础上，在本申请的一个实施例中，所述防雾层为表面活性剂层或金属氧化物层。
需要说明的是，所述防雾层可以通过对盖板100表面进行处理形成，也可以通过在所述盖板100表面通过镀膜的方式形成。镀膜所采用的方式可以为蒸镀、溅射、气相沉积和外延生长等。本申请对此并不做限定，具体视实际情况而定。
一般而言，表面活性剂层的防雾效果要优于金属氧化物层的防雾效果。表面活性剂层表面有水雾凝结时，表面活性剂层会将其拉成一层厚度均一的水膜，这层水膜在所述摄像模组的成像过程中相当于一块透光膜，并不会影响所述摄像模组的成像效果。因此在本申请的一个优选实施例中，所述防雾层优选为表面活性剂层。
具体地，所述表面活性剂层可以为聚丙烯酸酯层、不饱和聚酯层或聚脲烷层。本申请对所述表明活性剂层的具体种类并不做限定，具体视实际情况而定。
在上述实施例的基础上，在本申请的一个具体实施例中，所述加热层包括：
设置于所述盖板朝向所述底座一侧表面的ITO膜层；
设置于所述ITO膜层朝向所述底座300一侧表面的加热片或加热丝。
本实施例仅提供了一种可行的所述加热层的结构，其他具有加热功能的膜层结构也可用作所述加热层，本申请对此并不做限定，具体视实际情况而定。
在上述实施例的基础上，在本申请的另一个实施例中，所述基板400为印制电路板或柔性电路板。
所述基板400在起到配合所述底座300和盖板100形成密封腔的基础上，一般还需要在其表面贴装感光芯片和走线。而所述印制电路板和柔性电路板的走线固定，且有相应的焊盘方便感光芯片的固定和与走线的连接。但在本申请的其他实施例中，所述基板400还可以为玻璃板或合成塑料板，在这些实施例中，所述感光芯片可以通过粘贴胶或其他方式固定在所述基板400表面，通过导线实现电连接。本申请对所述基板400的具体种类并不做限定，具体视实际情况而定。
在上述实施例的基础上，在本申请的又一个实施例中，所述镜头200为塑胶镜头或玻璃镜头或玻塑混合镜头。本申请对所述镜头200的具体种类并不做限定，具体视实际情况而定。
在上述实施例的基础上，在本申请的一个优选实施例中，所述盖板100通过粘贴胶固定于所述台阶的台阶表面。
所述粘贴胶优选为自然固化胶。自然固化胶在涂抹到所述盖板100与所述台阶的阶位表面上后，只需要等到一定时间即可实现固化，而采不需要进行热固化的操作，避免了对密封腔的封闭性造成影响的情况出现。
在上述实施例的基础上，在本申请的另一个优选实施例中，所述盖板100为玻璃盖板或透明薄膜盖板。
需要说明的是，作为所述盖板100的材料除了要具有一定的硬度，以配合所述底座300和基板400形成密封腔之外，还需要具有透明的特性，以使外界光线可以通过盖板100进入所述镜头200，从而成像于所述感光芯片上。因此 本实施例仅举出了两种可行的盖板100种类，其他具有上述特性的材料均可以作为所述盖板100，本申请对所述盖板100的具体种类并不做限定，具体视实际情况而定。
相应的，本申请实施例还提供了一种电子设备，包括至少一个如上述任一实施例所述的摄像模组。
以电子设备中的智能冰箱为例，所述摄像模组可以设置于所述智能冰箱的冷藏室或冷冻室或保鲜室等室壁内部，以对所述智能冰箱内部的物品信息进行拍摄，然后通过智能冰箱的处理设备将所述摄像模组拍摄的照片向外界发送。
由于所述智能冰箱内部的湿度较大且温度较低，当所述智能冰箱开关门时，外部较热的空气会进入所述智能冰箱内部，冷热空气的相遇使得空气中的水分极易凝结。而所述摄像模组的防雾层的存在使得所述摄像模组具有良好的防雾效果。
并且所述摄像模组采用底座300配合基板400和盖板100形成密封腔，既起到了让所述镜头200和感光芯片处于封闭暗室的作用，还起到了容纳所述盖板的作用；因此所述摄像模组不需要增加独立的模组外壳容纳所述盖板，从而减小所述摄像模组的体积。
进一步的，当智能冰箱等电子设备需要应用所述摄像模组时，所述摄像模组的小体积降低了所述智能冰箱的箱体设计难度，使得所述摄像模组可以批量应用于各式各样的智能冰箱成为可能。
综上所述，本申请实施例提供了一种摄像模组及电子设备，其中，所述摄像模组采用底座300配合基板400和盖板100形成密封腔，所述密封腔既起到了让镜头和感光芯片处于封闭暗室的作用，还起到了容纳盖板的作用；因此不需要增加独立的模组外壳对内部部件进行保护，从而减小了摄像模组的体积；因此所述摄像模组不需要增加独立的模组外壳对所述摄像模组内部部件进行保护，从而减小了所述摄像模组的体积；并且所述镜头200与感光芯片均设置于所述密封腔中，不会受到外界冷热气流交互的影响。
进一步的，所述盖板100表面具有防雾层或加热层，以避免当所述摄像模组所处环境的湿度较大时在所述盖板100表面形成水雾或可通过自身加热使雾气快速散去，从而避免影响所述摄像模组成像效果的情况出现。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
