下面参照图1至图4描述根据本申请一些实施例所述的遮挡装置及车灯。
参见图1至图4所示，本申请的实施例提供了一种遮挡装置，用于遮挡发光组件800，发光组件800具有光路方向，遮挡装置设置于发光组件800的在光路方向的前方，该遮挡装置包括传动部200和多个遮挡组件，传动部200包括传动齿，多个遮挡组件中任一者均包括啮合齿，传动齿与啮合齿啮合，以驱动每一遮挡组件在第一状态和第二状态之间切换。其中，当遮挡组件处于第一状态时，多个遮挡组件拼接形成遮挡主体，沿光路方向观察，使得发光组件 800的至少部分被遮挡主体遮挡。当遮挡组件处于第二状态时，传动部200分别驱动多个遮挡组件相互分离，沿光路方向观察，使得发光组件800被多个遮挡组件暴露，如此，通过传动齿和啮合齿的啮合配合，当传动部200驱动遮挡组件在第一状态和第二状态之间切换的过程中，提高了多个遮挡组件与传动部200之间的传动精度，使得多个遮挡组件的运动行程可控，有效避免了遮挡装置遮挡不到位和显现不到位的现象发生。
如图1、图3和图4所示，所述传动齿可以为内齿圈210，对于所述多个遮挡组件中的每一遮挡组件，该遮挡组件可以包括旋转轴120，上述啮合齿为旋转齿轮130，该旋转齿轮130与旋转轴120同轴设置，所述旋转齿轮130与所述内齿圈210啮合，以驱动所述遮挡组件绕着所述旋转轴120旋转，使得所述遮挡组件在所述第一状态和所述第二状态之间切换，如此当驱动该内齿圈210旋转时，多个遮挡组件的旋转齿轮130可以同时被内齿圈210驱动，使得多个遮挡组件绕各自的旋转轴120旋转，实现遮挡组件在第一状态和第二状态之间切换。
优选地，上述传动部200还可以包括驱动齿220，遮挡装置还可以包括驱动组件300，驱动组件300与所述驱动齿220啮合，以驱动传动部200运动。
优选地，如图1、图3和图4所示，传动部200可以为环形垫圈，所述内齿圈210可以设置于所述环形垫圈的内圈。上述驱动齿220设置于所述环形垫圈的外圈的至少部分，如此，上述驱动组件300可以通过与驱动齿220啮合，实现驱动环形垫圈绕环形垫圈的轴线旋转，进而可以带动上述旋转齿轮130自转。
可选地，驱动组件300可以包括同轴设置的旋转电机和驱动齿轮，该驱动 齿轮可以于上述驱动齿220啮合，以实现传动。
然而需要说明的是，驱动组件并不局限于上述旋转电机和驱动齿轮的形式，图中未示出，只要能够与驱动齿啮合，为内齿圈提供动力，驱动组件还可以是其他形式，例如，驱动组件可以包括蜗杆和直线驱动部，该蜗杆与驱动齿啮合，直线驱动部与蜗杆一端连接，该直线驱动部可以是气缸、直线电机等。又如，驱动组件还可以包括上述直线驱动、环形齿轮和丝杠。直线驱动部与丝杠一端连接，环形齿轮内圈形成有与丝杠相匹配的内螺纹，环形齿轮与上述驱动齿啮合，环形齿轮套设于丝杠的外部。
在实施例中，如图1和图3所示，每一遮挡组件可以包括遮挡片110，上述旋转轴120设置于该遮挡片110的靠近所述内齿圈210的一侧。沿所述光路方向观察，所述遮挡主体呈圆形，所述多个遮挡组件的所述遮挡片110沿所述圆形的周向均布，如此，当遮挡组件由第一状态向第二状态之间切换的过程中，发光组件800能够自遮挡主体的中心逐渐被暴露，使得遮挡组件隐藏的过程形成发光组件800自中心逐渐绽放的动态效果；相似地，当遮挡组件由第二状态向第一状态之间切换的过程中，发光组件800能够自遮挡主体的边缘逐渐被隐藏，使得遮挡组件显现的过程形成发光组件800自边缘逐渐闭合收拢的动态效果，这使得发光组件800的暴露/隐藏过程增加炫酷感和科技感，有效地增添了车灯的高级感，提高了客户的使用体验。
参见图3，为了清楚地示出遮挡片110的结构，图中对其中一个遮挡组件进行隐藏处理。优选地，当遮挡组件处于第一状态时，在上述遮挡主体的径向方向上，自遮挡主体的边缘向遮挡主体的圆形所述遮挡片110的宽度渐缩，如此使得多个遮挡片110拼接能够形成上述圆形遮挡主体。
优选地，沿上述光路方向观察上述遮挡片110，遮挡片110可以是由三段首尾依次连接的圆弧围设形成的图形。参见图5所示，将遮挡片110的沿所述遮挡主体的周向延伸的边缘所形成的圆弧定义为第一圆弧111，并将其余两条圆弧分别定义为第二圆弧112和第三圆弧113。此外，将第一圆弧111与第三圆弧113两者围设的尖端定义为第一尖端115，将第二圆弧112与第三圆弧113两者围设的尖端定义为第二尖端116，将第一圆弧111与第二圆弧112两者围设的尖端定义为第三尖端117。
优选地，如图5所示，上述旋转轴120可以设置于第一尖端115处。第二圆弧112可以是以旋转轴120为轴且以第二尖端116的端部到旋转轴120的距离为半径做弧形成的。对应地，第三圆弧113可以与该遮挡片110相邻的且第三圆弧113所在侧的遮挡片110的第二圆弧112相贴合，如此以有效防止在遮挡片110旋转过程中与相邻的遮挡片110发生干涉。
可选地，如图5所示，遮挡片110还可以包括延伸沿114，该延伸沿114可以设置于遮挡片110的第三圆弧113所在的边缘，当遮挡组件处于第一状态时，延伸沿114能够有效地填补相邻两个遮挡片110之间的缝隙，防止遮挡组件处于第一状态时出现对发光组件800遮挡不完全的现象出现。
优选地，如图3至图5所示，每一所述遮挡组件可以包括导向柱140，所述导向柱140设置于所述遮挡片110的另一侧。
相应地，如图1、图2和图4所示，遮挡装置还可以包括导向部400，该导向部400可以包括导向槽410，所述导向柱140设置于所述导向槽410，在所述遮挡组件在所述第一状态和所述第二状态之间切换的过程中，所述导向柱140沿着所述导向槽410滑动，如此，进一步提高了遮挡组件的运动行程的精 度，进一步降低了遮挡装置遮挡不到位和显现不到位的现象发生的几率。
可选地，如图5所示，上述导向柱140可以设置于上述第三尖端117处，以提高遮挡组件的运动行程的精度。
参见图1至图5示出了遮挡装置包括6个遮挡组件的示例，然而不限于此，只要能够实现遮挡装置的显现和隐藏动作，遮挡组件的数量还可以是3个、4个、5个、7个、8个、9个、10个、11个、12个、13个、14个、15个、16个、17个、18个、19个、20个或者更多个。
在以上描述遮挡组件的特征的基础上，遮挡片110的形式可以包括以下三种示例。
示例一，所述遮挡片110可以为导光片，下述车灯还包括投射部，所述投射部发射光线照射所述导光片，使所述导光片发光。
示例二，上述遮挡片110可以为第一透光片，该第一透光片的一侧设有彩色镀膜，所述彩色镀膜的预定位置与其他位置的镀膜厚度不同，使得所述第一透光片的预定位置与所述其他位置的透光强度不同，以使得所述第一透光片呈现预定花纹。
可选地，可以通过激光雕刻的方式将预定位置的彩色镀膜的厚度减薄，以实现预定花纹。
示例三，遮挡片110为第二透光片，所述第二透光片的部分设有不透光镀层。
可选地，第二透光片的一侧可以均设有不透光的镀层，可以通过激光雕刻的方式将预定位置的方式将预定位置的不透光镀膜的厚度减薄，使得预定位置透光，以实现预定花纹。
优选地，上述每一遮挡组件还包括投射部，所述投射部设置于所述遮挡片110的远离所述圆形的圆心的一侧，如此进一步为发光组件800的暴露/隐藏过程增加炫酷感和科技感，有效地增添了车灯的高级感。
具体地，如图3和图4所示，投射部可以包括连接部分151和投射部分152，上述导向柱140可以贯穿该连接部分151，以实现连接部分151与遮挡片110两者之间的固定。该连接部分151自导向柱140延伸至该遮挡片110的第一圆弧111的外侧。上述投射部分152可以设置于连接部分151的位于第一圆弧111外侧的部分，该投射部分152设置于连接部分151的面对遮挡片110的一侧，以使得投射部分152能够与遮挡片110的侧部相对，以实现下述车灯的侧投状态。
优选地，上述投射部分152可以是LED。
可选地，如图1和图4所示，遮挡装置还可以包括导线部700，该导线部700呈环形，该导线部700可以套设于下述通道部分的外侧，该导线部700可以设置于下述第二安置部600的背离第一安置部500的一侧。导线部700还可以包括多个电连接器，电连接器的数量与上述遮挡组件的数量相等，多个电连接器沿导线部700的周向均布，使得电连接器与上投射部分152一一对应，上述投射部分152可以通过导线与该电连接器电连接，实现为投射部分152供电。
可选地，当遮挡组件处于第一状态时，所述发光组件800可以被开启，该发光组件800的光束可以直接照射至遮挡片110，以实现下述车灯的正投状态。
在实施例中，如图1、图2和图4所示，遮挡装置还可以包括第一安置部500，该第一安置部500包括彼此连接的通道部分和圆环部分，所述通道部分包括圆柱形通道，所述圆柱形通道的轴线与所述遮挡主体的轴线重合，所述圆 环部分设置于所述传动部200与所述多个遮挡组件之间，所述旋转轴120贯穿所述圆环部分，如此，将传动部200和旋转齿轮130与上述遮挡片110分隔，有效避免的遮挡片110在旋转过程中与传动部200和旋转齿轮130发生干涉，保证了遮挡装置的传动稳定性。
优选地，如图1和图2所示，所述发光组件800可以设置于该圆柱形通道的一端。对应地，上述圆环部分可以设置于该圆柱形通道的另一端，使得当遮挡组件处于第一状态时，上述遮挡主体可以通过遮挡该圆柱形通道便能实现对发光组件800的遮挡。换而言之，通道部分可以有效遮挡发光组件800发射的光线自发光组件800与遮挡主体两者之间的缝隙透出，有效地提升了上述挡光片正投射发光的效果。
进一步地，如图1、图2和图4所示，遮挡装置还可以包括第二安置部600，该第二安置部600呈圆环状，该第二安置部600可以套设于上述通道部分的外侧，所述第二安置部600设置于所述传动部200的背离所述多个遮挡组件的一侧，所述旋转轴120的两端分别与所述第二安置部600和所述遮挡片110连接，如此在第一安装部和第二安置部600两者之间能够围设形成传动空间，上述传动部200和旋转齿轮130能够在该传动空间内稳定传动，并且第一安装部和第二安置部600可以对传动部200和旋转齿轮130实现有效地限位。
