摄像模组及终端设备
本申请要求于2019年12月27日提交国家知识产权局、申请号为201911383235.2、申请名称为“摄像模组及终端设备”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
本申请属于电子设备技术领域，尤其涉及一种摄像模组及终端设备。
背景技术
手机等终端设备内通常都配备有摄像模组，摄像模组内设置有用于感光的传感器，而传感器前方通常都配备有滤光片以实现滤光。近年来，用户对手机等终端设备的拍摄像素要求越来越高，这样便导致摄像模组内传感器的尺寸也相应逐渐增大，而位于传感器前方的滤光片是通过支架悬空设置于传感器前方的，传感器的尺寸越大，滤光片的悬空面积也越大，进而会导致滤光片的装配稳定性下降。
发明内容
本申请的目的在于提供一种摄像模组及终端设备，旨在解决现有技术中的摄像模组中的滤光片随传感器的尺寸增大，其装配稳定性下降的技术问题。
为实现上述目的，本申请实施例采用如下技术方案：
第一方面，提供一种摄像模组，包括支撑机构、滤光片和对应滤光片设置的传感器，支撑机构包括基板、支撑架和缓冲物，支撑架设置于基板上，所述滤光片的边缘固定于所述支撑架上，所述缓冲物设置于所述基板和所述支撑架之间。如此一来，由于缓冲物能够在支撑架和基板之间提供有效支撑，这样即使滤光片相对于传感器增大了悬空面积，加大了滤光片作用在支撑架上的摆动力矩，支撑架也不会相对于基板发生明显晃动，反而能够在缓冲物的有效支撑下，保持其自身稳定，进而实现了对滤光片的稳定支撑，显著降低了其与滤光片之间碰触几率，进而保证了滤光片在悬空面积增大时的装配稳定性和完整性。
可选地，支撑架的数量和基板的数量均大于等于3，所有基板分布于传感器的外周，所有支撑架分布于滤光片的外周，并分别设置于对应的基板上。如此，各支撑架即可实现对滤光片周向的稳定支撑，保证了滤光片受力的各向同性，进一步提升了滤光片在悬空面积增大时的装配稳定性。
可选地，支撑架的数量和基板的数量均为2，两个基板分别设置于传感器的相对两侧，两个支撑架分别设置于两个基板上，并分别位于滤光片的相对两侧。这样一来，支撑架和基板的数量可具体限定为两个，一方面保证了滤光片的受力平衡性，另一方面也有效控制了摄像模组的整体制造成本。
可选地，支撑架朝向滤光片的一侧开设有搭接缺口，滤光片的边缘固定于搭接缺口内。通过设置搭接缺口，并使得滤光片的边缘固定于搭接缺口内，这样一方面实现了滤光片和支撑架快速且稳固地装配，另一方面搭接缺口还能够实现对滤光片的精确限位，进而也保证了滤光片和传感器的相对位置准确性。
可选地，滤光片的边缘通过粘胶固定于搭接缺口内。如此可保证滤光片和支撑架的装配稳定性。同时由于粘胶还具有一定的缓冲性能，这样也进一步降低了滤光片和支撑架之间的振动，提升了滤光片相对于支撑架的装配稳定性。
可选地，支撑架包括夹持部，滤光片的边缘夹设于夹持部内。滤光片和支撑架之间夹持装配，可降低滤光片和支撑架之间的装配成本，提升装配效率。
可选地，缓冲物设置于夹持部和对应的基板之间。具体地，缓冲物设置于夹持部和基板之间，可实现对滤光片作用于夹持部上的压力的直接抵消，进而显著降低了凸伸出支撑架的主体外的夹持部的晃动幅度。
可选地，支撑架为环形架，基板为环形板，基板环设于传感器外周，支撑架设置于基板上，并环设于滤光片的外周。通过将支撑架和基板均设定为环形，这样可增强支撑架和基板的整体力学性能，进而使得支撑架能够为滤光片提供更为稳定的支撑。
可选地，支撑架朝向滤光片的一侧边缘开设有装配环阶，滤光片的外周边缘搭设并固定于装配环阶上。当支撑架为环形时，通过在其朝向滤光片的一侧开设装配环阶，这样便在保证其对滤光片稳定支撑的同时，也提升了滤光片和支撑架的装配效率和精度。
可选地，缓冲物与基板或支撑架一体成型；或者，缓冲物为独立部件且装配于支撑架和基板之间。缓冲物与基板或支撑架一体成型可保证缓冲物的装配稳定性，而缓冲物为独立部件则可实现其相对于支撑架和基板的拆换维修。
可选地，缓冲物为弹性件；或者，缓冲物包括刚性件以及至少设置于刚性件面向支撑架的一面的缓冲层。具体地，当缓冲物要承受有限载荷时，缓冲物可为弹性件，当缓冲物要承受较大载荷时，其也可为具有缓冲层的刚性件。
可选地，弹性件为玻璃胶、免钉胶、结构胶、泡沫棉、弹簧或者封装有弹簧的硅胶块。具体地，通过将缓冲物设定上述具有弹性的物件，这样便能够为支撑架提供一种相对柔性的支撑，如此可允许支撑架存在有可控的弹性变形冗余，这样可保证支撑架和滤光片的装配关系具有弹性冗余，显著降低支撑架和滤光片在受到外界振动力时相互碰触受损的几率。
可选地，滤光片为红外截止滤光片。这样蓝玻璃可有效滤除外界红外光作用在传感器上形成的靶面虚像。进而可显著提升摄像模组的成像质量。
第二方面，提供一种终端设备，包括显示屏和上述的摄像模组，显示屏至少用于显示摄像模组拍摄的图像。
本申请实施例提供的具有上述摄像模组的终端设备，其内的滤光片可在悬空面积增大的同时也能够具有良好的装配稳定性，这样便使得终端设备能够在具有更大的拍摄像素的同时，也能够保证其具有良好的质量稳定性。

本申请实施例提供了一种终端设备，本申请实施例所称的终端设备包括但不限于摄像机、手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、或个人数字助理(personal digital assistant，PDA)等，本申请实施例对终端设备的具体类型不作任何限制。为了方便描述，在本申请实施例中的终端设备以手机为例进行说明，应理解，不能解释为对本申请的限制。
如图1～图3所示，终端设备(图未示)内包括有显示屏和摄像模组，摄像模组用于实现终端设备的拍照和录像功能，显示屏至少用于显示摄像模组拍摄的图像。摄像模组包括有镜头50、驱动镜头50运动的驱动马达60以及滤光片20和对应滤光片20设置的传感器30。
其中，镜头50和驱动马达60相连接，以在驱动马达60的带动下实现相对于传感器30的焦距调节。镜头50对应滤光片20以及传感器30设置。外界的光线即可通过镜头50和滤光片20入射于传感器30上，进而实现传感器30对外界图像信息的收集。
进一步地，摄像模组还包括有支撑机构10，支撑机构10包括基板11、支撑架12和缓冲物14。其中，基板11充当基准支撑物。而支撑架12则设置于基板11上，其用于固定滤光片20，滤光片20在和支撑架12装配时，其边缘部分固定于支撑架12上，以使其大部分区域都正对传感器30，这样可实现对滤光片20的滤光区域的充分利用。
如图1所示，为避免支撑架11和基板12由于尺寸误差在装配时发生相互干涉，支撑架11的部分可相对于基板12悬空设置，因此支撑架11和基板12之间便会形成有装配间隙13。摄像模组内的其他尺寸较小的电子器件40(比如电阻和电容等)可设置于装配间隙13内，以充分利用摄像模组内的装配空间装配间隙。例如，图1中左右两侧所示的装配间隙13均可用于容置电阻和电容等。将电子器件40设置于装配间隙13内，一方面充分利用了摄像模组内的空间从而可以减小模组尺寸，另一方面也能使电子器件40受到支撑架12和基板11的有效保护，进而显著提升电子器件40在受到冲击时的完好率。
电子器件40可能并不能完全填满装配间隙13。例如，图1中在基板与支撑架的滤光片连接部(也就是与滤光片连接的部分)之间仍然还有剩余的装配间隙。在本申请实施例中，在该剩余的装配间隙中设置缓冲物14。缓冲物14可以避免支撑架12在受到冲击时剧烈晃动。
如图4所示，支撑架12受到的来自滤光片20的下压力(图4中F1所示)以及下压力所产生的摆动力矩，同时还受到来自滤光片20和摄像模组内壳壁的方向相反的两横向抵接力(图4中F3和F4所示)。缓冲物14可对支撑架12施加向上的反作用力(图4中F2所示)，从而可对滤光片20施加于支撑架12的摆动力矩的进行有效缓冲和平衡，使得支撑架12实现受力平衡。
由于缓冲物14能够在支撑架12和基板11之间提供受力平衡，即使增加滤光片20面积(也就是相对于传感器30增大了悬空面积，加大了滤光片20作用在支撑架12上的摆动力矩)，支撑架12也不会相对于基板11发生晃动，实现了对滤光片20的稳 定支撑，显著降低了基板11与滤光片20之间碰触的几率，进而保证了滤光片20在悬空面积增大时的装配稳定性和完整性。
本申请实施例还提供的具有上述摄像模组的终端设备，其内的滤光片20可在悬空面积增大的同时也能够具有良好的装配稳定性，这样便使得终端设备能够在具有更大的拍摄像素的同时，也能够保证其具有良好的质量稳定性。
在本申请的一些实施例中，驱动马达60可以直接安装于支撑架12上。这样，支撑架12在承受来自滤光片20的摆动力矩的同时，也承受着来自驱动马达60的下压力。此时缓冲物14的存在也能够为支撑架12提供向上的反作用力，进而使得支撑架12能够实现对驱动马达60的有效支撑。
在本申请的另一些实施例中，如图5所示，支撑架12的数量和基板11的数量可以大于等于3，这样可以实现对滤光片20周向的稳定支撑。所有基板11分布于传感器30的外周。所有支撑架12也分布于滤光片20的外周，并分别设置于对应的基板11上。例如，支撑架12和基板11的数量相同，并且均匀分布与滤光片的外周。每一对支撑架12和基板11之间都设置缓冲物。通过将各支撑架12均匀分布于滤光片20外周，可使得滤光片20的外周边缘所受到的来自各支撑架12的作用力相互抵消，从而有效实现了滤光片20受力的各向同性，保证了滤光片20在摄像模组内的装配稳定性。此外，环设于传感器30外周的各基板11也能够为传感器30提供一层外围防护，如此便提升了传感器30在外界冲击振动作用下的生存能力。由于支撑架12和基板11对应或者成对设置，并且均匀分布于传感器30的外周，可实现对各支撑架12的稳定支撑。
在本申请的另一些实施例中，如图6所示，支撑架12的数量和基板11的数量均为2，两个基板11分别设置于传感器30的相对两侧，两个支撑架12分别设置于两个基板11上，并分别位于滤光片20的相对两侧。这样既可保证滤光片20的受力平衡和实现对滤光片20的稳定支撑，也可降低成本，因此实现对滤光片20的装配稳定性和摄像模组的制造成本之间的兼顾。此外，这种设置还可以节约摄像模组内的装配空间，使得装配完成后的摄像模组能够更为小巧紧凑。
在本申请的另一些实施例中，如图9和图10所示，支撑架12的滤光片连接部(即朝向滤光片20的一侧)包括搭接缺口121，滤光片20的边缘可固定于搭接缺口121内。通过将滤光片20的边缘固定于对应的搭接缺口121处，这样一方面实现了滤光片20和支撑架12快速且稳固地装配，另一方面搭接缺口121还能够实现对滤光片20的精确限位，进而也保证了滤光片20和传感器30的相对位置准确性。
可选地，滤光片20和支撑架12在具体装配时，可将滤光片20的边缘搭设于搭接缺口121内，进而首先实现滤光片20相对于支撑架12和传感器30的装配位置的确定，之后可通过点胶等多种方式将滤光片20的边缘固定于搭接缺口121内，进而实现滤光片20和支撑架12的稳定装配。
如图9和图10所示，滤光片20的相对两侧边缘分别通过粘胶124粘设于两搭接缺口121内。具体地，通过粘胶124将滤光片20的边缘粘设于搭接缺口121内，这样可保证滤光片20和支撑架12的装配稳定性。
可选地，粘胶124可选择为免钉胶，一方面，由于免钉胶良好的粘接能力，从而 有效保证了滤光片20和支撑架12的装配稳定性。另一方面，由于免钉胶由树脂合成，不含有甲醛等有害物质，那么在摄像模组内使用免钉胶，能够使得摄像模组的制造更为环保，进而也使得具有该摄像模组的手机等终端设备更具环保优势。
在本申请的另一些实施例中，如图11所示，支撑架12的滤光片连接部(朝向滤光片20的一侧)有夹持部122，滤光片20的边缘夹设于夹持部122内。例如，夹持部122可以包括两个夹持臂，用于夹持滤光片20的边缘。夹持部122可以降低滤光片20和支撑架12之间的装配成本和提升装配效率。同时，将滤光片20边缘夹持于夹持部122内，既实现了对滤光片20的周向支撑，也实现了对滤光片20的上下限位，从而进一步降低了滤光片20在受到振动时所发生的共振或上下晃动幅度。
可选地，滤光片20边缘夹持于夹持部122的位置可涂覆粘胶124或包覆保护膜(图未示)，以防止滤光边缘和夹持部122硬碰触而发生应力集中，造成夹持部122的开裂。同时粘胶124或保护膜还能够填充滤光片20边缘和夹持部122的夹持缺口之间缝隙，使得滤光片20的边缘更为稳固地夹设于夹持部122内。例如，涂覆粘胶124或包覆保护膜可以位于两个夹持臂的相向的两个表面。
在本申请的另一些实施例中，如图11所示，缓冲物14设置于夹持部122和对应的基板11之间。具体地，装配间隙13可延伸于夹持部122和对应的基板11之间，缓冲物14设置于夹持部122和基板11之间，可实现对滤光片20作用于夹持部122上的压力的直接抵消，进而显著降低了凸伸出支撑架12的主体外的夹持部122的晃动幅度。
具体来说，由于夹持部122相对于支撑架12的主体是朝向滤光片20凸伸设置的，这样其也构成了相对于基板11的悬空状态，需要为其提供有效支撑，那么通过将缓冲物14设置于夹持部122和对应的基板11之间，这样缓冲物14即可有针对性地对夹持部122进行支撑，从而避免夹持部122受滤光片20的摆动力矩过大而发生断裂，保证了夹持部122的力学性能稳定性。
在本申请的另一些实施例中，如图7所示，支撑架12为环形架，基板11为环形板，基板11环设于传感器30外周，支撑架12设置于基板11上，并环设于滤光片20的外周。具体地，作为滤光片20和支撑架12装配的另一种具体形式，通过将支撑架12和基板11均设定为环形，这样可增强支撑架12和基板11的整体力学性能，进而使得支撑架12能够为滤光片20提供更为稳定的支撑。
另一方面，支撑架12和基板11的环形设计还为设于其内的滤光片20以及传感器30的周向提供保护，并在摄像模组内起到结构支撑件的作用，这样也可提升摄像模组的整体强度。
需要说明的是：支撑架12和基板11的上述环形设计，可适用于摄像模组在具有较大振动或冲击的环境中服役的情形，以充分确保对滤光片20在摄像模组内的装配稳定性。
在本申请的另一些实施例中，如图8所示，当支撑架12环形设计时，支撑架12朝向滤光片20的一侧边缘开设有装配环阶123，滤光片20的外周边缘搭设并固定于装配环阶123上。支撑架12可以为环形架时。通过将滤光片20的边缘搭设于装配台阶上，可实现滤光片20和支撑架12的快速对位。滤光片20和支撑架12完成对位后，再通过点胶的方式将滤光片20的边缘固定于装配台阶上，以实现滤光片20和支撑架 12的稳固装配。这样便在保证其对滤光片20稳定支撑的同时，也提升了滤光片20和支撑架12的装配效率和精度。
可选地，还可在装配台阶上覆设一层双面胶，当滤光片20和支撑架12对位安装时，可撕去双面胶上的保护膜，并将滤光片20的边缘直接粘设于双面胶上即可，如此可在保证滤光片20和支撑架12的稳固装配的同时，也进一步提升了滤光片20在装设于支撑架12时的装配效率。
同时，由于双面胶能够实现和滤光片20的面接触粘合，这样也保证了滤光片20和双面胶粘合位置的整体均匀性，从而使得滤光片20相对于支撑架12的装配更为稳固。
在本申请的另一些实施例中，缓冲物14与基板11或支撑架12一体成型；或者，缓冲物14为独立部件且装配于支撑架12和基板11之间。具体地，缓冲物14与基板11或支撑架12一体成型可保证缓冲物14相对于基板11或支撑架12的装配稳定性，而缓冲物14为独立部件则可实现其相对于支撑架12和基板11的拆换维修。
在本申请的另一些实施例中，缓冲物14为弹性件；或者，缓冲物14包括刚性件以及至少设置于刚性件面向支撑架12的一面的缓冲层。具体地，当缓冲物14要承受有限载荷时，缓冲物可为弹性件，而当缓冲物14要承受较大载荷时，其也可为具有缓冲层的刚性件，以保证其具有足够的强度。
在本申请的另一些实施例中，如图9和图10所示，弹性件为玻璃胶、免钉胶、结构胶、泡沫棉、弹簧或者封装有弹簧的硅胶块。具体地，具体地，通过将缓冲物14设定上述具有弹性的物件，这样便能够为支撑架12提供一种相对柔性的支撑，如此可允许支撑架12存在有可控的弹性变形冗余，这样可保证支撑架12和滤光片20的装配关系具有弹性冗余，显著降低支撑架12和滤光片20在受到外界振动力时相互碰触受损的几率。
可选地，缓冲物14可为上述一种或几种物件的组合物，比如可将弹簧封装于玻璃胶、免钉胶或硅胶内，以增强缓冲物14的整体韧性，使其能够承受更大的载荷作用。
在本申请的上述各种实施例中，缓冲物14可以是以下形式。
如图9所示，第一种具体实现方式是将缓冲物14设定为玻璃胶，在具体使用时，可首先将玻璃胶涂覆于基板11上的对应位置，再将支撑架12的对应位置粘胶124于玻璃胶上，这样当玻璃胶固化后，其可牢固地粘合于支撑架12和基板11之间，保证了其相对于支撑架12和基板11粘合位置的稳固性，这样也使得缓冲物14在承受振动或冲击作用时不易自基板11上脱落。而玻璃胶固化后具有较佳的柔韧性，这也使得缓冲物14能够对支撑架12所受到的下压力或承受的摆动力矩进行有效吸收和缓冲。
第二具体实现方式是将缓冲物14设定为免钉胶，在具备玻璃胶的上述优势的同时，免钉胶可更为牢固地粘接于支撑架12和基板11，从而进一步提升了其相对于支撑架12和基板11粘合位置的稳固性。
且如上所述，作为一种不含甲醛的环保胶剂，使用免钉胶也能够使得摄像模组的制造更具环保性。同时，免钉胶在使用时，得益于其良好的粘接能力，无需将胶沾满整个基板11，仅需以点胶的方式粘设于基板11对应位置即可，如此可显著节省摄像模组的整体制造成本。
第三种具体实现方式是将缓冲物14设定为结构胶，由于结构胶的粘合对象较为广泛，其可用于金属、陶瓷、塑料、橡胶、木材等同种材料和不同种材料之间的粘接，这样也使得缓冲物14对基板11和支撑架12的材质要求更为宽容。
如此，无论基板11和支撑架12为同种或不同材质，结构胶均可实现在基板11和支撑架12之间的牢固粘设。那么当摄像模组应用于振动或冲击较为频繁的使用环境中时，结构胶的存在便实现了对支撑架12在面临频繁振动冲击作用时的稳定支撑。
而由于结构胶还具有较大的承力载荷，且耐老化、高温和腐蚀，这使得其能够在摄像模组内稳定服役，并且还能够在服役寿命内保持稳定的粘接性能和缓冲性能。
第四种具体实现方式是将缓冲物14设定为泡沫棉，那么得益于泡沫棉良好的弹性变形能力，其可实现对对支撑架12所受到的下压力或承受的摆动力矩进行有效吸收和缓冲。同时，泡沫棉还具有质轻的特点，这样可显显著降低摄像模组的整体重量。
第五种具体实现方式是将缓冲物14设定为弹簧等弹性件，得益于弹簧良好地弹性形变性能和较佳地支撑性，其可对支撑架12实现良好的支撑作用，当支撑架12发生较为剧烈地晃动时，弹簧可对支撑架12提供有力的支撑力，以及时吸收和消除支撑架12的晃动。
如图10所示，第六种具体实现方式是将缓冲物14设定为封装有弹簧的硅胶块，这样通过弹簧和硅胶块的组合，一方面使得缓冲物14具有了较佳地弹性变形性能，使得缓冲物14能够为支撑架12提供良好的支撑，另一方面硅胶也抑制住了弹簧的多余弹跳，进而使得缓冲物14能够在短时间内有效抑制住支撑架12的晃动。可选地，作为缓冲物14其他的组合形式，还可将弹簧等弹性件封装于玻璃胶、免钉胶或结构胶内。
在本申请的另一些实施例中，滤光片20为红外截止滤光片。具体地，红外截止滤光片具体可为镀制有红外短波截止膜的蓝玻璃片等。那么得益于蓝色波长具有较高的穿透率，可过滤630nm以上的红外光，这样采用蓝玻璃片作为基材的红外截止滤光片即可有效滤除外界红外光作用在传感器30上形成的靶面虚像。进而可显著提升摄像模组的成像质量。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
