进一步的，在一实施例中，如图7所示，该传感器运动机构总成主要包括滑动部件13、运动底板12以及第一驱动电机14，第一驱动电机14作为驱动传感器总成4移动的电机，通过驱动连接件15(例如，连接杆)与运动底板12连接，驱动连接件15将第一驱动电机14产生的旋转扭矩传递给运动底板12，同时，滑动部件13与运动底板12转动连接，传感器总成4安装于运动底板12上，滑动部件13和运动底板12配合实现传感器总成4的曲线滑动功能。
详细的，如图4所示，在外壳1的靠近载具41与外壳1的安装面43的内表面44上开设有滑槽16，结合图8所示，滑槽16沿Y方向自外壳1的开设探测口2的一侧表面45向外壳1的开设探测口2的相对侧表面46延伸。滑动部件13滑设于滑槽16内，滑动部件13在外壳1内滑动，利用滑槽16对其滑动路线进行限定，运动底板12设置于滑动部件13的远离滑槽16的表面上，与滑动部件13转动连接，运动底板12和滑动部件13两者之间可相互转动，且可利用滑动部件13在滑槽16上限定的滑动路线，对运动底板12的滑动进行约束，第一驱动电机14通过驱动连接件15与运动底板12连接，驱动连接件15与运动底板12转动连接，利用第一驱动电机14和驱动连接件15向运动底板12传递旋转力矩，驱动运动底板12运动，容置于外壳1内的传感器总成4固定安装于运动底板12上，通过运动底板12的滑动实现传感器总成4在外壳1内部局限空间下的伸出及复位功能。当第一驱动电机14作业时，第一驱动电机14通过驱动连接件15传递旋转力矩至运动底板12，带动运动底板12转动，同时使滑动部件13在滑槽16内滑动，运动底板12和滑动部件13联动，实现运动底板12上每个点的曲线运动，从而实现传感器总成4的曲线滑动，也就是说，该传感器运动机构总成利用特殊的曲柄滑块传动机构实现传感器总成4在外壳1内的滑动，实现传感器总成4在局限空 间下的伸出及复位功能。
例如，在一个具体的实施例中，滑槽16可包括一个或多个线性滑槽。例如，如图8所示，滑槽16包括两个相互平行的线性滑槽，每个线性滑槽均分别沿Y方向自外壳1的开设探测口2的一侧表面45向外壳1的开设探测口2的相对侧表面46延伸，即线性滑槽的长度方向与Y方向平行。当第一驱动电机14工作时，第一驱动电机14通过驱动连接件15传递旋转力矩至运动底板12，使运动底板12相对于驱动连接件15以运动底板12和驱动连接件15转动的转动轴心为旋转中心转动，进而使运动底板12相对于滑动部件13以运动底板12和滑动部件13的转动轴心为旋转中心转动，以及滑动部件13在线性滑槽16内滑动，带动运动底板12沿线性滑槽16移动，也就是说，运动底板12和滑动部件13联动，使运动底板12转动并沿线性滑槽16线性移动，实现运动底板12上每个点的曲线运动，从而实现传感器总成4的曲线滑动。
在一实施例中，如图5所示，传感器总成4包括传感器包壳5、传感器47、支架11、清洗液管道10以及控制阀9。结合图13所示，传感器47的安装镜头48的相对一端52固定安装在运动底板12上，运动底板12围设传感器47的第一表面471、第二表面472、第三表面473，以确保传感器47在运动底板12上固定的稳定性。传感器包壳5装配于传感器47的安装镜头48的一端51，如图6所示，在传感器包壳5的内部开设有清洗液流道56，清洗液流道56的流道出口34朝向传感器47的镜头48的镜面49，清洗液管道10的出口端与清洗液流道56的流道入口相连通，清洗液由清洗液管道10输送至清洗液流道56内，并经流道出口34喷向传感器47的镜头48的镜面49，对传感器47的镜头48进行清洗作业，保证在任何工作环境中传感器47的镜头48的清洁度，进而保证传感器47的作业功能。此外，在清洗液管道10上设置有控制阀9，利用控制阀9控制清洗液管道10的通断及清洗液管道10内清洗液的流量，实现传感器47的镜头48的自动清洗，并在传感器47的第四表面474上安装有支架11，支架11与传感器47、运动底板12固定连接， 控制阀9、清洗液管道10固定于支架11上，从而利用支架11实现控制阀9、清洗液管道10在外壳1内的固定。其中，如图13所示，传感器47包括第一表面471、第二表面472、第三表面473和第四表面474，第一表面471、第二表面472、第三表面473、第四表面474依次首尾连接。在一个具体的实施过程中，控制阀9可选用电磁阀，控制清洗作业的开始与停止，并控制清洗液的使用量，其外形尺寸小，既节省空间，又轻巧美观，且反应更灵敏。
在传感器总成4的工作状态(即传感器47的工作状态)下，传感器运动机构总成将装配有传感器包壳5的传感器47的安装镜头48的一端51伸出外壳1外。如图5所示，传感器包壳5远离传感器47的镜头48的一端53周缘向远离传感器47的方向延伸设置有突起部42，当传感器包壳5通过探测口2伸出至外壳1的外部时，突起部42置于外壳1内，抵接于外壳1的一侧表面45在探测口2附近的内表面，限制传感器包壳5的运动并对探测口2进行封堵，从而传感器包壳5对传感器47起到保护的作用，并结合突起部42对探测口2进行封堵，以保证工作状态时外壳1内部的密封性。
在一实施例中，如图3–图5所示，该传感器组件还包括盖板运动机构6、盖板3以及第二驱动电机7，盖板运动机构6设置于外壳1的内部靠近探测口2的一端，位于外壳1的与开设探测口2的一侧表面45相邻的两内侧表面(内侧表面54、内侧表面55)，用于带动盖板3运动，盖板3与盖板运动机构6连接，即盖板3靠近外壳1的内侧表面54、内侧表面55的两端分别与设置在外壳1的内侧表面54、内侧表面55上的盖板运动机构6连接，第二驱动电机7与盖板运动机构6相连，驱动盖板运动机构6带动盖板3沿外壳1的开设探测口2的一侧表面45的方向运动。当在非工作状态时，传感器总成4回缩至外壳1的内部，盖板3位于探测口2处，对探测口2进行封堵，以保证非工作状态时外壳1内部的密封性，当在工作状态时，盖板3沿外壳1的开设探测口2的一侧表面45向远离探测口2的方向运动，即将盖板3从图3的初始位置移动至图4的升起位置，之后，传感器包壳5通过探测口2 伸出至外壳1的外部，突起部42置于外壳1内，对探测口2进行封堵，以保证工作状态时外壳1内部的密封性，从而利用盖板3以及传感器包壳5、突起部42尽可能保证外壳1内部的密封性，并结合传感器运动机构总成将传感器设计为可伸缩隐藏式。
在一实施例中，如图2所示，外壳1包括固定壳体27和包壳28，包壳28固定连接于固定壳体27的一侧表面上，包壳28与固定壳体27装配共同组成传感器组件的壳体总成。详细的，固定壳体27安装于载具41上，以将外壳1整体固定在载具41上，固定壳体27作为外壳1与载具41之间连接的部分，滑槽16开设于固定壳体27的靠近载具41与固定壳体27的安装面43的内表面44上，包壳28装配在固定壳体27上，形成相对封闭的外壳1，包壳28的靠近载具41与固定壳体27的安装面43的一端开设有探测口2，且传感器总成4的设置高度与探测口2的开设高度相对应，以便于传感器总成4通过探测口2伸出外壳1，当在非工作状态时，传感器总成4回缩至外壳1的内部，当在工作状态时，传感器总成4通过第一驱动电机14、滑动部件13和运动底板12移动至探测口2处，传感器包壳5通过探测口2伸出至外壳1的外部，突起部42置于外壳1内，对探测口2进行封堵。
在一个具体的实施例中，图3–图5所示，固定壳体27为一侧开口的壳体，需注意并理解的是，此处的固定壳体27的开口侧指的是上述中外壳1的一侧表面45，在Z方向上，固定壳体27的开口侧的下端(即内侧表面54、内侧表面55所在面靠近载具41与固定壳体27的安装面43的一端)与固定壳体27的靠近载具41与固定壳体27的安装面43的表面(即内表面44所在面)垂直，固定壳体27的开口侧的上端(即内侧表面54、内侧表面55所在面远离载具41与固定壳体27的安装面43的一端)相对固定壳体27的开口侧的下端向传感器总成4的方向倾斜预设角度，从而尽可能减小传感器组件整体所占空间的大小。包壳28用于封闭固定壳体27的开口侧的表面，扣合于固定壳体27的开口侧，从而包壳28和固定壳体27形成内部容置其他部件 的外壳1，其中，包壳28用于封闭固定壳体27的开口侧的表面的截面为折线形状，包壳28的形状大小与固定壳体27的开口侧的形状大小相对应，以保证包壳28和固定壳体27所形成的外壳1的相对密封性。
在本公开实施例中，Z方向与Y方向垂直。
需要注意并理解的是，本文中的垂直均并不一定指两者之间呈90°，也可以具有一定的倾斜角度。
进一步的，如图2所示，包壳28包括下端部57和与下端部57弯折连接的上端部58，下端部57与上端部58之间的夹角与预设角度相等，以保证包壳28折线形状的夹角与固定壳体27的开口侧的上下端之间的夹角相同，且下端部57与固定壳体27的开口侧的下端相匹配，上端部58与固定壳体27的开口侧的上端相匹配，进一步保证包壳28的形状大小与固定壳体27的开口侧相匹配，使包壳28扣合在固定壳体27的开口侧，完全封闭固定壳体27的开口侧的表面。相对应的，探测口2开设在包壳28的下端部57上，在传感器47的工作状态下，传感器47利用第一驱动电机14、滑动部件13和运动底板12通过探测口2伸出至外壳1处，在传感器47的非工作状态下，传感器47利用第一驱动电机14、滑动部件13和运动底板12回缩至外壳1内，实现传感器47的伸出及复位功能。
在一实施例中，如图2所示，包壳28通过卡扣结构50扣合于固定壳体27的一侧表面上，以实现包壳28与固定壳体27之间的固定连接。具体的，结合图1所示，卡扣结构50包括公扣29和母扣30，固定壳体27的与开口侧相邻的表面上均设置有多个公扣29，多个公扣29沿包壳28和固定壳体27的扣合线设置，包壳28上设置有与多个公扣29一一相配合的多个母扣30，从而通过母扣30卡设于公扣29上，将包壳28固定连接在固定壳体27上，结构简单，且易于安装拆卸。
此外，如图8和图14所示，在固定壳体27的远离包壳28的一侧表面上 开设有通口271，通口271处设置有用于封闭通口271的软连接26，软连接26在传感器组件装配时可被压缩，暂时缩小传感器组件在Y方向上的尺寸，软连接26由较软、可压缩量较大的材料制成，如硅胶、TPU等。
在具体的实施过程中，如图15所示，在载具41内设置有用于安装该传感器组件的安装支架40，例如，在汽车的车身内部设置安装支架40，或在飞行器本体的内部设置安装支架40，再结合图4所示，在固定壳体27的内侧表面54、内侧表面55各自所在面的外侧下端分别设置有安装耳35，通过安装耳35将固定壳体27固定连接在载具41的安装支架40的安装面43上。进一步的，如图15所示，当载具41固定该传感器组件的安装支架40的形状为“L”型，且在Y方向上，安装支架40与载具41(例如，车身或飞行器本体)之间的距离不大于传感器组件体正常状态下在Y方向上的宽度时，在进行装配时，该传感器组件整体需从(a)位置经图15的虚线达到(b)位置，从图15中可看出，从(a)位置到(b)位置的装配空间较为狭窄，安装支架40与载具41之间的距离不大于传感器组件整体正常状态下在Y方向上的宽度，不利于传感器组件的整体安装，此时，可在(a)位置处，将软连接26压缩或折叠入外壳1内，缩小传感器组件在Y方向上的尺寸，从而使传感器组件易于通过狭窄的装配空间达到(b)位置，当传感器组件向上装配到达(b)位置固定安装后，再可利用传感器47的向后推力将软连接26展开。
在一实施例中，如图4所示，该传感器组件还包括限位部件8，限位部件8设置于固定壳体27的靠近载具41与固定壳体27的安装面43的内表面44上，且位于滑槽16靠近外壳1的开设探测口2的一侧表面45的一端，在传感器总成4向外伸出过程中，利用限位部件8将传感器总成4固定在工作位置，限制其继续往外伸出。具体的，在固定壳体27的靠近载具41与固定壳体27的安装面43的内表面44靠近探测口2的一端开设有与限位部件8相配合的卡扣凹槽17，限位部件8通过卡接于卡扣凹槽17内，固定于固定壳体27的内表面44上，对滑动部件13的滑动进行限位。
在一个具体的实施例中，如图10所示，限位部件8包括限位本体36和两个卡块37，两个卡块37设置于限位本体36的靠近外壳1的与开设探测口2的一侧表面45相邻的两内侧表面(内侧表面54、内侧表面55)的两端(限位本体36的一端361、限位本体36的另一端362)，卡扣凹槽17开设在固定壳体27的靠近载具41与固定壳体27的安装面43的内表面44上，与卡块37相配合，在装配限位部件8过程中，卡块37扣入固定壳体27的卡扣凹槽17中，使限位部件8与固定壳体27固定连接。
在一实施例中，如图10所示，在限位本体36上开设有一个或多个通槽38，以尽可能减小传感器组件的整体重量，需注意并理解的是，所开设的各个通槽38的形状大小可以相同，也可以不相同，且所开设的通槽38不能影响限位部件8的其他结构设计，且需保证限位部件8本身的结构强度。
进一步的，如图9和图10所示，限位部件8朝向滑动部件13的一侧面上开设有多个定位孔31，即定位孔31开设在限位本体36朝向滑动部件13的一侧面上，多个定位孔31沿限位本体36纵向等距离分布，相应的，滑动部件13朝向限位部件8的一侧面上设置有多个与定位孔31相匹配的定位柱32，通过定位柱32插入定位孔31内，限位部件8阻挡滑动部件13继续滑动，从而将传感器总成4固定在指定的工作位置处。
如图8所示，由于滑槽16开设在外壳1的内表面44靠近探测口2的一端上，滑槽16与外壳1的后侧表面(即外壳1的开设探测口2的相对侧表面46)之间具有预设距离，也就是说，滑动部件13将传感器总成4移动回外壳1的内部时，滑槽16在非工作位置有结构限位，故而在非工作位置不需要额外的限位部件。
进一步的，如图9所示，在滑动部件13背向限位部件8的一侧面上设置有多个弹性凸起33，多个弹性凸起33沿滑动部件13纵向分布，当传感器总成4回到非工作位置时，第一驱动电机14提供的旋转扭矩使滑动部件13的 弹性凸起33受到挤压而形变，一方面，可避免滑动部件13与外壳1之间的碰撞，另一方面，在非工作位置时，滑动部件13与外壳1之间通过形变的弹性凸起33相接触，能够保证在载具震动时其不会晃动发出异响。
在一实施例中，如图9所示，弹性凸起33包括线性部331和半弧形部332，线性部331靠近滑动部件13的一侧表面与滑动部件13固定连接，半弧形部332的一端与线性部331的远离滑动部件13的一侧表面的一端相连，半弧形部332的另一端与线性部331的远离滑动部件13的一侧表面的另一端开口设置，在传感器47的非工作状态时，滑动部件13与外壳1之间通过形变的半弧形部332相接触。
在一个具体的实施过程中，驱动连接件15可与第一驱动电机14的输出轴39集成，例如，驱动连接件15与第一驱动电机14的输出轴39一体成型，减少零部件的数量以及装配步骤。另外，由于在传感器总成4移动时，滑动部件13与固定壳体27滑动摩擦，因此，滑动部件13可使用摩擦系数极低的材料制作，如聚四氟乙烯、聚甲醛等。
在一实施例中，结合图11、图12和图13所示，运动底板12的远离传感器总成4的表面121上设置有滑动插销22和驱动连接件插销21。
滑动部件13的中部设置有第一轴套24，滑动插销22插入第一轴套24，且滑动插销22的远离运动底板12的一端穿设至第一轴套24外，滑动插销22的远离运动底板12的一端上设置有用于轴向定位的滑动挡圈25。其中，滑动插销22与运动底板12过盈压接，例如，当运动底板12的生产工艺为注塑或压铸，滑动插销22可以与运动底板12集成为同一部件。第一轴套24与滑动部件13过盈压接，在运动底板12与滑动部件13有相对旋转时，第一轴套24与滑动插销22滑动摩擦，若摩擦的速度与压力均较小，且滑动部件13由自润滑材料制成，第一轴套24可以与滑动部件13集成为同一部件。滑动挡圈25用于防止滑动部件13与运动底板12装配之后有竖直方向上的相对 运动，其也可用卡簧代替。
驱动连接件15靠近运动底板12的一端设置有第三轴套19，驱动连接件插销21插入第三轴套19，且驱动连接件插销21的远离运动底板12的一端穿设至第三轴套19外，驱动连接件插销21的远离运动底板12的一端上设置有用于轴向定位的驱动连接件挡圈23。其中，第三轴套19过盈压接在驱动连接件15上，若驱动连接件15选用摩擦系数极低的材料制成，如聚四氟乙烯、聚甲醛等，第三轴套19可与驱动连接件15集成为同一部件。驱动连接件插销21与运动底板12过盈压接，若运动底板12的生产工艺为注塑或压铸，驱动连接件插销21可以与运动底板12集成为同一部件。驱动连接件挡圈23用于防止驱动连接件15与驱动连接件插销21装配之后有竖直方向上的相对运动，其可用卡簧代替。
在一实施例中，结合图8、图11、图12和图13所示，第一驱动电机14安装于外壳1的靠近载具41与固定壳体27的安装面43的内表面44上，具体的，外壳1的靠近载具41与固定壳体27的安装面43的内表面44上设置有第二轴套18，第二轴套18的设置位置与第一驱动电机14的输出轴39的设置位置相对应，驱动连接件15靠近第一驱动电机14的一端设置有电机驱动插销20，电机驱动插销20的靠近第一驱动电机14的一端上设置有与第一驱动电机14的输出轴39相配合的凹槽结构201，通过第一驱动电机14的输出轴39插入凹槽结构201内，将第一驱动电机14与驱动连接件15相连，电机驱动插销20的远离第一驱动电机14的一端插入第二轴套18。其中，第二轴套18过盈压接在固定壳体27上，其使用摩擦系数极低的材料制成，如聚四氟乙烯、聚甲醛等，或采用具有聚四氟乙烯、聚甲醛涂层的金属件。电机驱动插销20与驱动连接件15过盈压接，电机驱动插销20的凹槽结构201与第一驱动电机14的输出轴39对配，若驱动连接件15的生产工艺为注塑或压铸，电机驱动插销20可以与驱动连接件15集成为同一部件。
以上是对本实施例提供的传感器组件的各个部件、它们之间的连接关系进行了介绍，下面结合图1–图15，对传感器组件的工作原理进行详述。
在本公开实施例中，传感器47在非工作状态下，传感器组件的结构如图1所示，传感器47在工作状态下，传感器组件的结构如图2所示。传感器组件的外壳1内的部件初始位置如图3所示，此时，盖板3处于盖板运动机构6的底端，传感器总成4处于缩回状态。当第二驱动电机7工作时，驱动盖板运动机构6作业，带动盖板3运动至升起位置，如图4所示。之后，第一驱动电机14启动并通过驱动连接件15传递旋转力矩至运动底板12，旋转力矩使使运动底板12相对于驱动连接件15以运动底板12和驱动连接件15转动的转动轴心(即驱动连接件插销21的轴心)为旋转中心转动，进而使运动底板12相对于滑动部件13以运动底板12和滑动部件13的转动轴心(即滑动插销22的轴心)为旋转中心转动。其中，运动底板12转动的方向与角度取决于驱动连接件插销21与滑动插销22的相对位置关系。如图9与图10所示，滑动部件13朝向限位部件8的一侧面上设置有2个定位柱32，相应的，限位部件8朝向滑动部件13的一侧面上设置有2个定位孔31。当滑动部件13移动至外壳1靠近探测口2的一端与限位部件8接触时，定位柱32插入定位孔31内，传感器47到达工作位置。此外，第一驱动电机14具有自锁功能，使载具41在震动时，传感器47可以固定在工作位置，工作性能更稳定可靠。
当传感器47的镜头48在工作状态下受到污染，需要清洗镜头48时，控制阀9控制清洗液通过清洗液管道10进入传感器包壳5的清洗液流道56内。清洗液从传感器包壳5位于传感器47的镜头48附近的流道出口34喷出，将镜头48清洗干净。
当传感器总成4需要复位时，第一驱动电机14启动并通过驱动连接件15传递反向旋转力矩至运动底板12。滑动部件13依照原路径将传感器总成4移 动回非工作位置。如图9所示，滑动部件13背向限位部件8的一侧面上有2个弹性凸起33，当传感器47回到非工作位置时，第一驱动电机14提供的旋转扭矩使滑动部件13的弹性凸起33受到挤压形变。第一驱动电机14断电后，弹性凸起33的形变与第一驱动电机14的自锁使传感器47固定在非工作位置，在载具41震动时不会晃动发出异响。
第一驱动电机14的输出轴39与电机驱动插销20的凹槽结构201对配。当第一驱动电机14启动之后，驱动连接件15的另一端以第一驱动电机14的输出轴39的轴心为旋转中心做圆弧运动。驱动连接件挡圈23使驱动连接件15与运动底板12之间只允许以驱动连接件插销21轴心为旋转中心的相对转动。驱动连接件15与驱动连接件插销21在传感器总成4运动过程中有滑动摩擦，第三轴套19起到润滑作用。类似的，滑动挡圈25使滑动部件13与运动底板12之间只允许以滑动插销22轴心为旋转中心的相对转动。滑动部件13与滑动插销22在传感器总成4运动过程中有滑动摩擦，第一轴套24起到润滑作用。在传感器总成4运动过程中，电机驱动插销20与固定壳体27有滑动摩擦，第二轴套18起到润滑作用。
综上，本公开实施例公开一种传感器组件，利用特殊的曲柄滑块传动机构和盖板运动机构，实现了传感器在局限空间下的伸出及复位功能，降低载具的风阻和噪声，并对传感器起到保护的作用，且该传感器组件还具有清洗传感器镜头的功能，保证传感器持续长时间的正常工作和最佳的工作状态。
