这些中国专利申请在此通过引用整体并入本文中。
技术领域
本发明在第一方面涉及一种摄像头装置。具体地，本发明涉及具有高稳定性和高可靠性的摄像头装置。本发明在第二方面还涉及至少双目的摄像头装置。具体地，本发明涉及镜头模组可方便地绕镜头筒的光轴旋转并且还具有高稳定性和高可靠性的至少双目的摄像头装置。本发明在第三方面还涉及至少双目的摄像头装置。具体地，本发明涉及镜头间距可方便地被调整、具有高稳定性和高可靠性的并且镜头模组可方便地绕镜头筒的光轴旋转的至少双目的摄像头装置。
背景技术
随着诸如汽车的机动车及人工智能的普及，机动车内部需要装配ADAS(高级驾驶辅助系统)摄像头装置，其包括单目ADAS摄像头或者双目ADAS摄像头。
传统的机动车用摄像头装置如说明书附图1-1、图2和图3-1所示。如图1-1所示的，传统摄像头装置一般包括前壳1、后壳2和摄像头模组3。这些组件例如通过螺钉21等组装起来形成如图3-1所示的摄像头装置。
其中，如图2所示的，所述的摄像头模组3一般包括镜头22、镜座23和印刷电路板组件(PCBA)。所述PCBA一般包括集成在一起的光传感器14和印刷电路板11，所述光传感器14能够接收来自所述镜头22的光信号，并将该光信号转变成电信号，同时将转变的电信号传输给所述印刷电路板11。所述光传感器14与所述印刷电路板11集成在一起形成一块作为硬板的PCBA。在装配过程中，将镜头22安装在镜座23上，镜座23再通过螺钉21等固定在所述PCBA硬板上从而形成摄像头模组3。最后，整个摄像头模组3可借助于所述PCBA硬板通过螺钉21或本领域已知的其它多种方式固定于所述前壳1或后壳2。
近年来，机动车内部的单目ADAS摄像头装置已经渐渐被双目ADAS摄像头装置所取代。其主要原因是因为双目摄像头不仅有单目摄像头的全部功能，而且还能识别深度信息。但是双目摄像头装置对两个镜头之间距离公差的要求特别严苛。
传统的机动车用双目摄像头装置如说明书附图1-2、图2和图3-2所示。如图1-2所示的，传统双目摄像头装置一般包括前壳1、后壳2和两个摄像头模组3。这些组件例如通过螺钉21等组装起来形成如图3-2所示的双目摄像头装置。
在双目摄像头装置的情况下，两个单颗摄像头模组3借助于所述PCBA硬板通过螺钉21或本领域已知的其它多种方式固定于所述前壳1或后壳2。
在上述传统的摄像头装置(包括传统的单目和双目摄像头装置)中，镜头22和镜座23的镜头组合体整体位于所述PCBA硬板之前，从而所述组合体的重心必然位于所述PCBA硬板前方。这导致在汽车运行过程中所述镜头组合体随着汽车颠簸而不断振动。所述组合体的重心距所述PCBA硬板越远，这种振动就越剧烈。这种振动使得所述镜头组合体与所述PCBA硬板之间的连接、所述PCBA硬板与前壳1或后壳2之间的连接和/或镜头22和镜座23之间的连接都有可能松动，从而进一步使得镜头22在汽车运行期间随着汽车的颠簸相对于车体 的振动更加剧烈。这导致所述传统摄像头装置的稳定性和可靠性严重不足。
另外，传统的双目摄像头装置采用的固定所述两个单颗摄像头模组3的方式要求在所述两个模组中的两个传感器的安装角度在安装前就要彼此匹配。一旦所述安装角度由于诸如螺钉等的固定装置原因或者由于如上所述的振动等原因而出现偏差时，就很难将所述安装角度进行调整使其互相匹配。
另外，传统的双目摄像头装置采用的结构尺寸链较长，镜头与镜头之间的距离一致性难以把控；算法为此需要进行更多的运算来满足其设计需求。
另外，在传统的双目摄像头装置中，固定所述两个单颗摄像头模组3的方式使得所述两个镜头之间的镜头间距一般不易调整。然而在很多情况下都需要使镜头间距能够被方便地调整。中国专利CN201637998U和CN210321626U对此进行了尝试，然而在这些文献中的尝试都没有在满足镜头间距调整要求的同时克服或降低如上所述的关于稳定性或安装角度等方面的缺陷。

在第二方面，本发明要实现的目的通过本发明的发明人设计的前端镜头模块定位的方案得以实现。具体地，本发明采用前端镜头模块定位的设计，依靠镜头模块本身与上壳进行定位；实现了镜头与镜头之间的距离公差的准确控制，极大缩短了双目镜头之间的尺寸链。即，本发明的至少双目的摄像头装置可以准确控制镜头与镜头之间的距离公差(即baseline)。同时本发明的至少双目的摄像头装置还可以方便地调整镜头模组安装时的角度，完全能够满足现有算法对双目摄像头位置度的需求。
在第三方面，本发明要实现的目的通过本发明的发明人设计的前端镜头模块定位和长条形通孔设计的方案得以实现。具体地，本发明采用前端镜头模块定位的设计，依靠镜头模块本身与上壳进行定位；实现了镜头与镜头之间的距离公差的准确控制，极大缩短了双目镜头之间的尺寸链，同时采用长条形通孔的设计，可以任意移动镜头模块的相对位置；待移动到适合位置时，再将用紧固机构固定。此方式可以用于不同客户对模组与模组之间的不同需求，操作简便，实用性强。 即，本发明的至少双目的摄像头装置可以准确控制镜头与镜头之间的距离公差(即baseline)，同时还可以方便地调节镜头间距以及方便地调整模组安装时的角度，完全能够满足现有算法对双目摄像头位置度的需求。
进一步地，本发明提供的至少双目的摄像头装置还优选在镜头模块中设有调节机构，在装配完成之前和/或之后，至少两个镜头模组可方便地绕镜头筒的光轴旋转，从而可以方便地调整两个镜头模组中的两个传感器的安装角度，进而控制其成像的角度以使其相互匹配。在所述调节过程中线路板均不受力，均为镜头调节机构受力；故线路板不会发生形变、胶水也不会受力开裂；满足功能要求的同时不会影响模组本身的可靠性。。
更进一步地，在本发明提供的至少双目的摄像头装置中，优选的前端镜头模块定位和后端固定印刷电路板的方案还使得镜头相对于车体的振动幅度被降低到很小，从而本发明的至少双目的摄像头装置的良好稳定性和可靠性得到保证。另外，在本发明提供的至少双目的摄像头装置中，传感器板与印刷电路板之间优选采用诸如软排线等的软连接；可以有效吸收装配及调节过程中产生的公差。

本领域技术人员能够理解，在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述前壳1和所述后壳2的形式及其连接方式没有特别限制，只要所述前壳1和所述后壳2相互配合地固定连接在一起形成位于它们之间的空腔即可。在此，术语“空腔”意思是闭合的空间，该闭合空间的边界应当被理解为包括：前壳1和后壳2的外表面；以及由前壳1和后壳2的外表面与存在于前壳1和后壳2上的任何孔洞、通道或缝隙的侧壁形成的边界所限定的面。该空间可通过位于所述前壳1和/或所述后壳2上的任意形状和大小的孔洞、通道或缝隙等与外界相通。本领域技术人员可考虑通过一体成型、浇铸、焊接、粘合剂粘结、螺钉固定、铆钉固定和/或卡口固定等多种方式将所述前壳1和所述后壳2相互配合地固定连接在一起。事实上，在本发明中，所述前壳1和所述后壳2甚至可以被理解为分别起到它们各自作用的第一固定支架和第二固定支架，而在所述支架外部还可存在另外的壳体。另外，所述前壳1和所述后壳2之间并没有明确界限，在将它们视为一个整体壳的情况下(例如将它们一体成型的情况下)，所述前壳1和所述后壳2可被认为是所述整体壳的相对靠前的部分和相对靠后的部分。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述前壳1和/或后壳2除了限定的通孔6或6’外，还任选进一步存在另外的通孔，该另外的通孔可例如用于所述印刷电路板11与外界的连接和信号传递等多种目的(如图4中所示，后壳2具有另外的通孔)。另外，将所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300固定安装在诸如汽车等的机动车上也可通过存在于所述前壳1和/或后壳2上的另外的通孔和/或本领域技术人员公知的位于所述前壳1和/或后 壳2外表面上的另外的装置实现，所述另外的装置例如可以是如图1-1、1-2、3-1、3-2、8-1、8-2或8-3中示出的位于前壳1相对两侧的突出物。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述镜头模块15的镜头筒7任选用于容纳镜片。所述传感器板10位于所述空腔内部使得透过所述任选的镜片经过所述镜头筒7的光线能够传输到达在所述传感器板10上的传感器14。
在如上所述的第一方面的摄像头装置100中，所述传感器板10可通过本领域技术人员已知的任何方式固定连接于所述前壳1和/或所述后壳2和/或所述印刷电路板11和/或所述镜头筒7，优选所述传感器板10固定连接于所述镜头筒7。
在如上所述的第二或第三方面的至少双目的摄像头装置200或300中，所述传感器板10需要固定连接于所述镜头筒7。
所述固定连接的方式没有特别限制，只要所述方式能够使得透过所述任选的镜片经过所述镜头筒7的光线能够到达在所述传感器板10上的传感器14即可。在此，例如可以考虑通过螺钉、铆钉、粘合剂、浇铸、焊接、卡扣、一体成型或集成在一起等多种方式实现所述固定连接。
例如，在本发明的优选的第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，如图6至7所示的，所述镜头筒7可通过粘合剂13与传感器板10固定连接形成镜头模块15。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，传感器14是本领域中普通的光传感器，其能够接收来自镜头筒7的光信号，并将该光信号转变成电信号，同时将转变的电信号传输给所述印刷电路板11。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述传感器板10与所述印刷电路板 11的连接方式没有特别限制。例如可以考虑通过螺钉、铆钉、焊接、粘合剂、浇铸等多种方式将它们固定连接在一起。甚至可以考虑如上文背景技术部分中所述那样，使所述传感器14集成到所述印刷电路板11中成为一块PCBA硬板实现所述连接。在这种情况下，所述传感器14和所述印刷电路板11集成而得PCBA硬板。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，优选的是，所述印刷电路板11固定连接于所述后壳2。
在所述传感器板10固定连接于所述镜头筒7和所述印刷电路板11固定连接于所述后壳2的情况下，进一步优选使所述传感器板10与所述印刷电路板11通过软连接的方式进行连接。例如，优选使所述传感器板10通过软排线12连接于所述印刷电路板11，如图5-1、5-2、5-3、6和7所示的。另外还优选在这种情况下，所述传感器板10和/或所述印刷电路板11与存在于它们之间的软板形成软硬结合板，从而实现所述传感器板与所述印刷电路板的软连接(这种情况在附图中未示出)。
在如上所述的第二或第三方面的至少双目的摄像头装置200或300中，优选的是，所述至少两个摄像头模组15的多个传感器板10不仅可通过软连接的方式连接于多个印刷电路板11(附图中未示出)，也可以通过软连接的方式连接于一个印刷电路板11(如图5-1、5-2和5-3中所示的)。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，在所述印刷电路板11连接于所述后壳2的情况下，所述连接的方式没有特别限制，只要所述方式能够使得所述印刷电路板11连接于所述后壳2即可。本领域技术人员可考虑通过一体成型、浇铸、焊接、粘合剂粘结、螺钉固定、铆钉固定和/或卡口固定以及甚至软连接等多种方式实现这一目的。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述通孔6(除第三方面中的长条 形通孔6’外)和所述镜头筒7的截面形状没有特别限制，只要其使得所述紧固机构能够将所述镜头模块15固定于所述前壳1即可。例如所述截面形状可以是凸多边形、近似正多边形、椭圆形或圆形，特别优选圆形。
另外，在如上所述的第三方面的至少双目的摄像头装置300中，如图5-3、8-3、21和22中所示的，所述一个或多个通孔6或6’中的至少一个是长条形通孔6’，并且有至少一个所述镜头筒7穿过至少一个所述长条形通孔6’。此处，术语“长条形通孔”意思是该通孔的垂直于所述镜头筒7的光轴的截面呈长条形。所述至少一个镜头筒7能够在所述长条形通孔6’的不同位置处由相应的紧固机构固定于所述前壳1，从而使得本发明的第三方面的至少双目的摄像头装置300的至少两个摄像头模组的镜间距离可以被方便地调整。
此处，所述长条形可以是长圆形或近似长方形等多种形式。在存在多个长条形通孔6’的情况下，各个长条形通孔6’的形状可以相同或不同。另外，所述长条形通孔6’的长度没有特别限制，本领域技术人员可根据实际情况对其做出调整。
另外，在如上所述的第三方面的至少双目的摄像头装置300中，如附图22所示的，还优选有至少两个所述镜头筒7同时穿过一条所述长条形通孔6’。在这种情况下，本发明的第三方面的至少双目的摄像头装置300的至少两个摄像头模组的镜间距离可以被方便地在更大范围内被调整，大大方便了例如在不同情况下调整测距精度等的需求。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述镜头筒7的筒体前端和筒体后端的长度比例没有特别限定，但优选所述筒体前端和筒体后端的分界线使得在使用状态下，所述镜头模块15在空腔外部部分的重量和在空腔内部部分的重量相差较小(例如相差<约200％，优选相差<约100％，更优选相差<约50％，最优选相差<约20％)，这使得所述镜头模块15在机动车运行过程中振动的幅度相对较小。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少 双目的摄像头装置200或300中，所述镜头模块15可以是分体式镜头模块(由固定结合在一起的多个组件组成的镜头模块)，也可以是一体式镜头模块，但优选是一体式镜头模块。在所述镜头模块15是一体式镜头模块的情况下，所述镜头筒7是一体成型的。所述一体式镜头模块使得本发明的上述优点更加突出。
在如上所述第一方面的摄像头装置100或第二或第三方面的至少双目的摄像头装置200或300中，所述紧固机构的作用是将所述镜模块15头固定于所述前壳1。
另外，在如上所述的第二或第三方面的至少双目的摄像头装置200或300中，所述紧固结构还允许所述镜头模块15在固定于所述前壳1之前绕所述镜头筒7的光轴旋转。
特别地，在如上所述的第三方面的至少双目的摄像头装置300中，用于将其中所述镜头筒7穿过所述长条形通孔6’的镜头模块15固定于所述前壳1的紧固机构还允许该镜头模块15在所述长条形通孔6’的不同位置处固定于所述前壳1。
本领域技术人员能够认识到包括但不限于以下方式的紧固机构能够实现上述这些目的：
方式1(如图5-1、5-2、5-3、6、7、8-1、8-2和8-3所示的)：所述紧固机构包括螺母4。在此情况下，所述镜头筒7具有在所述筒体后端的外周边沿镜头筒径向方向向外延伸的凸环9，并且所述镜头筒7还具有在所述筒体前端的外周边上形成的能够与所述螺母4配合的螺纹8，其中所述螺母4的最大外径大于所述通孔6的内径，所述凸环9的最大外径大于所述通孔6的内径，所述螺母4与所述螺纹8配合并借助于位于所述筒体后端的凸环9将所述镜头筒7夹持固定于所述前壳1，从而使所述镜头模块15固定于所述前壳1，最后形成如图8-1、8-2和8-3所示的本发明的优选的第一方面的摄像头装置100和第二或第三方面的至少双目的摄像头装置200或300。
在上述方式1的情况下，在本发明的第二或第三方面的至少双目的摄像头装置200或300中，所述凸环9优选在面向所述空腔内部的 表面上具有凹坑、穿孔或凸起(如图5-2、5-3、6、7、19和20所示的)，使得借助于所述凹坑、穿孔或凸起可以利用调节治具24或手动使安装角度不合适的镜头筒7(如图20中左侧的图所示的)围绕所述镜头筒7的光轴旋转(如图20中左侧的图中实心箭头所示的方向)，从而相应地调节固定连接于所述镜头筒7的传感器板10的安装角度(如图20中右侧的图所示的)。
方式2(如图9所示的)：与方式1类似，所述紧固机构包括螺母4。然而，在此情况下，所述镜头筒7具有在所述筒体前端的外周边沿镜头筒径向方向向外延伸的凸环9，并且所述镜头筒7还具有在所述筒体后端的外周边上形成的能够与所述螺母4配合的螺纹8，其中所述螺母4的最大外径大于所述通孔6(通孔6的附图标记在图9中未标明)的内径，所述凸环9的最大直径大于所述通孔6的内径，所述螺母4与所述螺纹8配合并借助于位于所述筒体前端的凸环9将所述镜头筒7夹持固定于所述前壳1，从而使所述镜头模块15固定于所述前壳1。
在上述方式2的情况下，另外优选在所述螺母4的面向所述空腔内部的表面上具有凹坑、穿孔或凸起，使得借助于所述凹坑、穿孔或凸起可以利用调节治具或手动使所述螺母4方便地配合旋接在镜头筒7的筒体后端的螺纹8上(这种情况在附图中未示出)。
