随着汽车工业的迅猛发展和车身电子技术的飞速进步，车载摄像模组越来越被广泛地应用到了各种汽车上。尤其是随着智能化和无人驾驶的应用，车载摄像模组作为汽车的视觉系统，越来越多的应用于汽车上。
车载用摄像模组往往直接安装在车辆车身的周围，由于车辆所行驶的环境存在多样性，尤其是在一些环境较为恶劣的地方，例如，道路崎岖不平，雨雪天气等环境下。因此，安装在车身上的摄像模组的可靠性要求要比普通摄像模组高。现有的车载摄像模组主要由镜头、镜座、线路板等组成，其中镜头与镜座主要通过粘接剂直接粘接，其主要为面与面之间的粘接。如果在粘接位置处存在瑕疵，当车辆行驶在恶劣环境下式，这些瑕疵容易被振动等因素扩大，导致模组上开裂甚至镜筒与镜座脱离的质量问题，严重影响车辆的行驶安全性。

具体实施方式
为了更清楚地说明本发明实施方式或现有技术中的技术方案，下面将对实施方式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一些实施方式，对于本领域普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
在针对本发明的实施方式进行描述时，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”所表达的方位或位置关系是基于相关附图所示的方位或位置关系，其仅是为了便 于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此上述术语不能理解为对本发明的限制。
下面结合附图和具体实施方式对本发明作详细地描述，实施方式不能在此一一赘述，但本发明的实施方式并不因此限定于以下实施方式。
如图1所示，根据本发明的一种实施方式，本发明的一种摄像模组，包括镜筒11，镜座12，连接件13，设置于镜筒11内的透镜组2。在本实施方式中，镜筒11和镜座12相互同轴设置，并且镜筒11和镜座12通过连接件13相互连接。在本实施方式中，镜筒11上设置的筒体上设置有一径向变大的法兰111。连接件13分别与法兰111的下表面111a和镜座12的上端面121相互连接，从而实现了镜筒11与镜座12的同轴连接。在本实施方式中，连接件13与镜座12的连接位置之间和/或连接件13与镜筒11的连接位置之间设置有用于嵌合连接的连接结构14。本发明的摄像模组还设置有成像组件。成像组件接收透镜组2传输的光线，进而实现了本发明的镜头的成像。通过设置连接结构14，从而使连接件13分别与镜筒11和镜座12连接位置的连接更加紧密牢固，避免了镜筒11和镜座12之间产生脱离的弊端，提高了整个摄像模组外壳的连接强度和使用寿命。同时，通过连接结构14还能够在镜筒11与连接件13的连接位置之间和/或镜座12与连接件13的连接位置之间形成密封回路，进而使本发明的壳体的密封性能更高，尤其是将本发明使用在车载模组领域，进而使本发明的模组的密封性能优良，更加能够适用于车载模组领域，尤其在恶劣环境下的适应性更高，使用寿命更长。
如图1所示，根据本发明的一种实施方式，连接结构14包括第一连接部分141和与第一连接部分141形状相匹配的第二连接部分142。在本实施方式中，第一连接部分141设置于连接件13上，第二连接部分142设置于镜座12和/或镜筒11上。在本实施方式中，第一连接部分141与第二连接部分142为相对应设置，即如果只在镜座12设置有第二连接部分142，则仅在连接件13与镜座12连接的一侧设置第一连接部分141；如果只在镜筒11上设置有第二连接部分142，则仅在连接件13与镜筒11连接的一侧设置第一连接部分141；如果在镜座12和镜筒11均设置有第二连接部 分142，则在连接件13的两侧均设置第一连接部分141。通过上述方式，可以根据本发明的使用环境选择性的在镜筒11和/或镜座12上设置第二连接部分142，根据实际使用环境在摄像模组容易脱离的位置设置第二连接部分142进而增加了其连接位置的连接强度，在不容易脱离的位置可选择地设置第二连接部分142，进而使本发明的摄像模组的外壳的设计及制造过程得到简化，不仅使本发明的使用范围更广，同时还提高了设计及制造效率，节约了成本。
根据本发明的一种实施方式，第二连接部分142仅设置于镜座12上。在本实施方式中，则第二连接部分142可设置于镜座12的侧壁与端面的连接位置(参见图2或图4)上或者设置于端面(参见图5、图8、图10)上或者设置于侧壁(参见图6、图9)上。
根据本发明的另一种实施方式，第二连接部分142仅设置于镜筒11上。在本实施方式中，则第二连接部分142位于镜筒11的侧壁(参见图11)、端面(参见图12)或侧壁与端面的连接位置上。
如图14所示，根据本发明的另一种实施方式，第二连接部分142设置于镜座12和镜筒11上。在本实施方式中，则第二连接部分142分别位于镜筒11和镜座12的侧壁、端面或侧壁与端面的连接位置上。
根据本发明的一种实施方式，第二连接部分142为截面形状呈多边形或弧形的凹槽或凸起，则第一连接部分141为与第二连接部分142形状相配合的凸起或凹槽。在本实施方式中，第二连接部分142的截面形状呈三角形、矩形、梯形、半圆形或半椭圆形。当然，第二连接部分142的截面形状还可以设置为其它形状，其可以为规则的，也可以为不规则的，在此不再赘述。
根据本发明的一种实施方式，在本实施方式中，第二连接部分142在镜座12和/或镜筒11上的延伸方向与镜筒11的轴线方向相交(参见图2、图3、图4、图5、图6、图7、图9、图11和图12)或平行(参见图8和图10)设置。
如图2、图4和图5所示，根据本发明的一种实施方式，当第二连接部分142的截面形状为三角形时，若第二连接部分142设置在镜筒11和/ 或镜座12的端面或侧壁与端面的连接位置上，则第二连接部分142的两个侧面之间的夹角A满足：0°＜A＜90°。参见图2所示，在本实施方式中，第二连接部分142为三角形凹槽，且其设置在镜座12的上端面121与外侧面122的连接位置(即第二连接部分142的开口一部分在上端面121上，另一部分在外侧面122上)，其一个侧边与镜筒11的中心轴X相互垂直(即处于水平位置)，其另一个侧边与镜筒11的中心轴X相互倾斜设置，因此在第二连接部分142的两个侧面之间构成一夹角A，且夹角A满足0°＜A＜90°。通过上述设置，将第二连接部分142设置在在镜筒11和/或镜座12的侧壁与端面的连接位置上，并且第二连接部分142的侧面相对镜筒11的中心轴线倾斜设置，进而使第二连接部分142以及与其相互嵌合的第一连接部分141在镜座12和连接件13的连接位置之间构成“倒钩形状”进而使连接件13与镜座12之间的连接更加牢固稳定。同时，通过形成的“倒钩形状”在连接位置处构成迂回的封闭结构，进而对阻挡外部灰尘、水汽等杂质的进入有益，保护了摄像模组内的组件的安全。需要指出的是，第二连接部分142处于水平位置的侧边同样也可以与镜筒11的中心轴X相互倾斜设置，只要满足上述夹角范围即可。
结合图2和图3所示，根据本发明的一种实施方式，当第二连接部分142的截面形状为三角形时，第二连接部分142的两个侧面之间的连接位置处设置有过渡结构144。在本实施方式中，过渡结构144可以设置为过渡圆角或过渡倒角。通过设置过渡结构144，从而有利于减小第二连接部分142底部位置的应力集中，有利于提高本发明的镜筒11或镜座12的结构强度，同时，通过设置过渡结构144也有利于第二连接部分142的加工，提高了成品良率，以及加工效率。
参见图4所示，根据本发明的另一种实施方式，第二连接部分142为三角形凹槽，且其设置在镜座12的上端面121与内侧面123的连接位置(即第二连接部分142的开口一部分在上端面121上，另一部分在内侧面123上)，其一个侧边与镜筒11的中心轴X相互垂直(即处于水平位置)，其另一个侧边与镜筒11的中心轴X相互倾斜设置，因此在第二连接部分142的两个侧面之间构成一夹角A，且夹角A满足0°＜A＜90°。通过上述设 置，将第二连接部分142设置在在镜筒11和/或镜座12的侧壁与端面的连接位置上，并且第二连接部分142的侧面相对镜筒11的中心轴线倾斜设置，进而使第二连接部分142以及与其相互嵌合的第一连接部分141在镜座12和连接件13的连接位置之间构成“倒钩形状”进而使连接件13与镜座12之间的连接更加牢固稳定。同时，通过形成的“倒钩形状”在连接位置处构成迂回的封闭结构，进而对阻挡外部灰尘、水汽等杂质的进入有益，保护了摄像模组内的组件的安全。需要指出的是，第二连接部分142处于水平位置的侧边同样也可以与镜筒11的中心轴X相互倾斜设置，只要满足上述夹角范围即可。
参见图5所示，根据本发明的另一种实施方式，第二连接部分142为三角形凹槽，且其设置在镜座12的上端面121(即第二连接部分142的开口在上端面121上)，其一个侧边与镜筒11的中心轴X相互倾斜设置，其另一个侧边与镜筒11的中心轴X也为相互倾斜设置，因此在第二连接部分142的两个侧面之间构成一夹角A，且夹角A满足0°＜A＜90°。通过上述设置，将第二连接部分142设置在在镜筒11和/或镜座12的端面上，并且第二连接部分142的侧面相对镜筒11的中心轴线倾斜设置，进而使第二连接部分142以及与其相互嵌合的第一连接部分141在镜座12和连接件13的连接位置之间构成“倒钩形状”进而使连接件13与镜座12之间的连接更加牢固稳定。同时，通过形成的“倒钩形状”在连接位置处构成迂回的封闭结构，进而对阻挡外部灰尘、水汽等杂质的进入有益，保护了摄像模组内的组件的安全。在本实施方式中，第二连接部分142两个侧面与水平方向的夹角中，最小的夹角取值要小于90°，即图5中的夹角B满足B＜90°。
如图6所示，根据本发明的一种实施方式，当第二连接部分142的截面形状为三角形时，若第二连接部分142设置在镜筒11和/或镜座12的侧壁上，则第二连接部分142的两个侧面之间的夹角A满足：0°＜A＜180°。在本实施方式中，第二连接部分142设置在镜座12的外侧面122上，第二连接部分142的两个侧面之间的夹角A满足：0°＜A＜180°。在本实施方式中，第二连接部分142的开口方向与镜筒11的中心轴X是相互垂直的， 当然也可以是相互倾斜的。当然，在镜筒11上设置时，其设置方式与上述相同或相近，在此不再赘述。通过上述设置，将第二连接部分142设置在在镜筒11和/或镜座12的侧壁上，进而使第二连接部分142以及与其相互嵌合的第一连接部分141在镜座12和连接件13的连接位置之间构成“倒钩形状”进而使连接件13与镜座12之间的连接更加牢固稳定。同时，通过形成的“倒钩形状”在连接位置处构成迂回的封闭结构，进而对阻挡外部灰尘、水汽等杂质的进入有益，保护了壳体内的组件的安全。
如图7所示，根据本发明的一种实施方式，当第二连接部分142的截面形状为梯形时，第二连接部分142设置在镜筒11和/或镜座12的侧壁上，第二连接部分142两个倾斜侧面之间的夹角A满足：0°＜A＜180°。在本实施方式中，第二连接部分142的开口方向与镜筒11的中心轴X是相互垂直的，当然也可以是相互倾斜的。当然，在镜筒11上设置时，其设置方式与上述相同或相近，在此不再赘述。通过上述设置，将第二连接部分142设置在在镜筒11和/或镜座12的侧壁上，并且第二连接部分142的侧面相对壳体的中心轴线倾斜设置，进而使第二连接部分142以及与其相互嵌合的第一连接部分141在镜座12和连接件13的连接位置之间构成“倒钩形状”进而使连接件13与镜座12之间的连接更加牢固稳定。同时，通过形成的“倒钩形状”在连接位置处构成迂回的封闭结构，进而对阻挡外部灰尘、水汽等杂质的进入有益，保护了摄像模组内的组件的安全。
根据本发明的一种实施方式，当第二连接部分142的截面形状为三角形时，若第二连接部分142设置在镜筒11和/或镜座12的端面或侧壁与端面的连接位置上，则第二连接部分142相对镜筒11的轴线倾斜设置，即第二连接部分142的延伸方向与镜筒11的轴线方向相交。在本实施方式中，第二连接部分142截面为三角形时，其角平分线所在的面与中心轴X相互倾斜设置，参见图2至图5所示。通过上述设置，进而保证了第二连接部分142与镜筒11中心轴线之间的倾斜状态，使连接件13与镜筒11和/或镜座12连接位置的组成的扣合结构能够把镜筒11和/或镜座12拉紧，减小或避免镜筒11和/或镜座12的振动，对保证摄像模组的外壳的强度有利。
如图8所示，根据本发明的另一种实施方式，第二连接部分142的截 面形状可以为梯形。在本实施方式中，第二连接部分142为设置在镜座12上的凸起，并且其延伸方向与镜筒11的轴线方向相平行。如图8所示，第二连接部分142的截面为一呈倒置的梯形，即其远离上端面121的一端的宽度要大于靠近上端面121的一端的宽度。因此在第二连接部分142与上端面121之间形成“倒钩状结构”，从而保证了连接件13与镜座12连接的稳定性。当然第二连接部分142还可以设置为其它形状，在此不再赘述。另外，第二连接部分142还可以设置在镜筒11上，其设置方式与上述相同，在此不再赘述。相应的，连接件13上的第一连接部分141与第二连接部分142的形状相匹配设置。在本实施方式中，第二连接部分142与镜座12为可拆卸连接的，也可以为一体设置的。如图8所示，在镜座12上具有一安装第二连接部分142的凹槽，第二连接部分142的下端与该凹槽相互嵌合的固定连接，其上端即构成了“倒钩状结构”。
如图9所示，根据本发明的另一种实施方式，第二连接部分142的截面形状还可以为弧形。其设置在镜座12是外侧面122上。当然，弧形可以为圆弧、椭圆弧。该弧形的长度可以为劣弧也可以为优弧。在本实施方式中，第二连接部分142的截面的弧形采用的是优弧(即圆心角大于180°)。通过设置为优弧，其在开口位置处收缩，进而使连接更加牢固可靠。通过上述设置，保证了第一连接部分141与第二连接部分142相互嵌合连接后，第二连接部分142能够有效避免第一连接部分141的脱离，保证了本发明的连接强度。
如图10所示，根据本发明的一种实施方式，第二连接部分142为设置在镜座12上的梯形凹槽，，并且该第二连接部分142在镜座12上的延伸方向同样与镜筒11的轴向相平行，该梯形凹槽的上端开口小，因此起到了良好的限位拉紧作用。为进一步提高本发明的连接稳定性则在第二连接部分142的内侧壁上还设置有防滑结构143。在本实施方式中，防滑结构143可以为随机分布的凸起、凹槽或螺纹等的一种或多种的组合，也可以为规则布置的凸起、凹槽的一种或多种的组合。
根据本发明的另一种实施方式，第二连接部分142为凸起，则在第二连接部分142的外侧壁上还设置有防滑结构143。在本实施方式中，防滑 结构143可以为随机分布的凸起、凹槽或螺纹等的一种或多种的组合，也可以为规则布置的凸起、凹槽的一种或多种的组合。
通过上述设置，在第二连接部分142的其它设置结构中也可设置防滑结构143，进一步保证了本发明的连接强度。
如图11所示，根据本发明的一种实施方式，第二连接部分142的截面为三角形，且其设置在法兰111的外侧面111b上，其设置方式与前述第二连接部分142在镜座12上的设置方式相同，在此不再赘述。
如图12所示，根据本发明的一种实施方式，第二连接部分142的截面为三角形，且其设置在法兰111的下端面111a上，其设置方式与前述第二连接部分142在镜座12上的设置方式相同，在此不再赘述。
根据本发明的一种实施方式，连接件13通过粘接剂分别与镜筒11和镜座12相互粘接；或者，连接件13采用具有粘性的高分子聚合物填充至镜筒11和镜座12之间并固化后形成。参见图1所示，镜筒11上没有设置第二连接部分142，在镜座12上设置有第二连接部分142，相应的在连接件13上也只设置有与镜座12上的第二连接部分142相匹配的第一连接部分141.在本实施方式中，通过在具有第二连接部分142的镜座12涂覆具有粘性的高分子聚合物将第二连接部分142填充，并且形成连接件13的初始形状，完成后将镜筒11安装定位到连接件13的上表面上，镜筒11安装到位后，对连接件11进行固化，从而使连接件13的上表面与镜筒11相互固定连接，从而最终形成连接件13。当然还可以通过预制连接件13的方式将镜筒11和镜座12相互连接。例如，首先在镜座12的上端面121和第二安装部分142中涂覆粘接剂，将连接件13与镜座12相嵌合的安装，然后在连接件13的上表面涂覆粘接剂，将镜筒11安装定位到涂覆有粘接剂的连接件13的上表面上，最后将组装好的摄像模组进行固化即可完成组装。
结合图1和图14所示，根据本发明的另一种实施方式，在镜筒11和镜座12上均设置有第二连接部分142，相应的在连接件13上也具有两个第一连接部分。在本实施方式中，第二连接部分142的设置方式与前述方式相同，在此不再赘述。连接件13的连接方式也与前述内容相同，在此不再赘述。
上述内容仅为本发明的具体方案的例子，对于其中未详尽描述的设备和结构，应当理解为采取本领域已有的通用设备及通用方法来予以实施。以上所述仅为本发明的一个方案而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
