背景技术
传感器为电子产品的重要部件。有些传感器的工作与接收到的信号的强度相关。例如红外传感器等光学传感器。其接收到超过某一阈值的光强时才会确认某一状态。有些情况下，传感器需要设置在电子产品的内部，通过电子产品上的安装孔发射及接收信号。由于孔壁的反射，会造成传感器探测结果的失真，形成误判。此外，电子产品用于潮湿环境时，可能会造成传感器内部进入水汽。传感器内部的水汽会影响传感器件的使用寿命，并且有可能影响传感器信号的收发，造成探测结果的失真。

为了保持本申请实施例的以下说明清楚且简明，本申请省略了已知功能和已知部件的详细说明。
参见图1至图4，本申请实施例提供一种清洁设备的壳体，壳体上具有用于装配传感器2的安装孔1，安装孔1的孔壁11倾斜设置，以使安装孔1的横截面积自内向外呈逐渐增大的趋势变化，孔壁11上设有反光结构12，反光结构12将孔壁11分成多个反射面。
本申请实施例提供了一种清洁设备的壳体。壳体上具有用于装配传感器2的安装孔1，安装孔1的孔壁11倾斜设置，以使安装孔1的横截面积自内向外呈逐渐增大的趋势变化，孔壁11倾斜设置可以避免安装孔1较深时，影响传感器2的信号发送及接收。孔壁11上设有反光结构12，反光结构12将孔壁11分成多个反射面。由此，通过反光结构12的不同设计，可以控制来自孔壁11的反射光的方向，从而可以减少孔壁11的反射对传感器2的影响。参见图3和图4，图中以带箭头的线条表示反光结构12对光线的反射路径。通过设置反光结构12将较大面积的孔壁11作为反射面打破，形成多个反射面，从而改变反射路径及有效反射面积。减少了壁面反射进入传感器2的光线等信号，降低了造成误判的影响。
清洁设备上设有悬崖传感器。悬崖传感器装配于安装孔1的底部。传感器2发射的信号由安装孔1的开***向地面，由地面反射后，传感器2接收地面反射的信号。当清洁设备行走至悬崖处(具有较大落差处)，传感器2接收的信号会发生变化，从而可以判断清洁设备处于悬崖边缘，通过转向、停车等从而能够避免清洁设备坠落。如果地面反射的信号经安装孔1的孔壁11反射进入传感器2，使传感器2接收到的信号的量较经地面反射直接进入传感器2的信号增加。当经孔壁11反射进入传感器2的信号足够多时，将使传感器2做出错误判断。例如，悬崖传感器采用红外传感器时，发射和反射的信号为红外光。本申请在孔壁11上设置反光结构12将所述孔壁11分成多个反射面，改变反射路径及有效反射面积，能够降低孔壁11反射造成的影响。
本申请实施例中，反光结构12的具体构造及形式不限，只要能够 将大面积的孔壁11分成多个反射反射面，降低大面积反射的整体效应即可。反光结构12可以是在孔壁11上形成的规则的几何体，也可以是不规则的几何体。规则的几何体包括多面体。反光结构12采用多面体，可以将光等信号反射至特定方向，能够保证孔壁11上的信号至少一半不被反射至传感器2。多面体的具体性形状不限。
参见图2和图3，一些实施例中，孔壁11上具有多级台阶，多级台阶形成反光结构12。本申请实施例中，反光结构12采用多级台阶。台阶结构至少具有台阶面121和侧面122两个面。在孔壁11上的多级台阶属于上述多面体的一种。孔壁11上形成多级台阶，将整个孔壁11分成多个反射面，避免孔壁11整体作为大的反射面，将信号反射至传感器2。台阶结构能够保证一半的信号不被反射至传感器2。
参见图3，一些实施例中，台阶包括台阶面121和侧面122。台阶面121与安装孔1的横截面平行。台阶面121平行于横截面，即台阶面121与安装孔1的中心线3垂直。台阶面121能够将信号反射出安装孔1，避免进入传感器2。
一些实施例中，台阶面121为亚光面。本申请实施例中通过采用亚光面的台阶面121，使反射光线形成漫反射，进一步消弱反射光强度。
本申请实施例中，反光结构12的表面还可以进行消光处理。示例性实施例中，在反光结构12的表面形成消光膜。例如，在台阶面121上形成消光膜，进一步消弱反射光强度。
一些实施例中，侧面122与安装孔1的横截面垂直。侧面122平行于安装孔1的中心线3，与台阶面121相配合，可以保证至少一半的信号被反射出安装孔1，而不会进入传感器2，大大降低了传感器2的误判。
本申请实施例中，每级台阶可以是连续的，也可以是断续的。
参见图2和图3，一些实施例中，每级台阶沿孔壁11连续延伸。每级台阶沿孔壁11周向连续延伸。形成台阶的方式简单易行，形式多样。
示例性实施例中，在孔壁11上进行横向刻划，沿周向在孔壁11上刻划出V形槽。V形槽的两个槽壁相互垂直。V形槽的两个槽壁形成一级台阶的台阶面121和侧面122。通过刻划的方式，在孔壁11上形 成连续的多级台阶，破坏连续光滑面的反射光。
当然，反光结构12的形成方式不限于上述在孔壁11上直接铣切等方式刻划而成。也可以是在孔壁11上附加反光结构12。示例性实施例中，可以是在孔壁11上涂覆胶层，通过模压的方式形成反光结构12(例如多级台阶)，然后固化。胶层可以是光固胶。通过紫外线光照的方式固化。
相邻两级台阶可以是直接相连接。相邻两级台阶直接相连接时，其中一个台阶的侧面122与另外一个台阶的侧面122直接相连接。相邻两级台阶也可以是间接相连接。相邻两级台阶间接相连接时，其中一个台阶的侧面122与另外一个台阶的侧面122通过过渡面124相连接。例如，图2和图3所示实施例中，过渡面124由没有刻划到的孔壁11形成。
本申请实施例中，安装孔1的壁面形状不限。可以是不规则形状，也可以是规则形状。
一些实施例中，安装孔1的壁面为锥台面。锥台面包括圆台面和棱锥台面。示例性实施例中，安装孔1的壁面为棱锥台面。
一些实施例中，安装孔1设于壳体的底部，并且传感器2定向为在清洁设备处于操作状态下时垂直向下发射或接收信号。例如，清洁设备的悬崖传感器2需要设置在壳体的底部，以便向地面发送信号。
一些实施例中，安装孔1靠近壳体的边缘设置，靠近边缘一侧的孔壁11具有缺口123。在靠近壳体的边缘一侧的孔壁11上形成缺口123，可以避免孔壁11对信号的影响。该缺口123的大小不限，例如，可以是自安装孔1的开口至孔底全部形成缺口123，也可以是部分形成缺口123。即形成缺口123一侧的孔壁11的高度低于其他部分的孔壁11的高度。
本申请实施例提供了一种清洁设备，其包括上述任一实施例的清洁设备的壳体。
本申请实施例的清洁设备还包括悬崖传感器2。悬崖传感器2装配于上述安装孔1的底部。悬崖传感器2可以采用红外传感器2和激光传感器2。
本申请实施例的清洁设备包括扫地机器人、拖地机器人、拖扫机器人和消毒机器人等。
本申请实施例还提供一种传感器，其可以例如为上述任一个实施例中描述的清洁设备中的传感器2。当然，本公开绝不仅限于此。也就是说，在如下各个实施例中描述的传感器也可以是清洁设备中除了如上传感器2之外的其它任何传感器。
参见图5至图7，在本申请的实施例中，传感器包括外壳和设于外壳内的传感器组件60。外壳包括主体部分10和盖体20。
主体部分10的一端开口。盖体20用于封闭主体部分10的开口。盖体20与主体部分10通过螺纹件40连接。
密封件30设于盖体20与主体部分10之间，以使主体部分10与盖体20之间密封连接。
本申请实施例中，外壳上还可以具有镜片50。镜片50用于外壳内的传感器组件60的收发信号通过。
本申请实施例提供的传感器中，主体部分10的一端开口，开口可以通过盖体20密封，主体部分10和盖体20之间设置密封件30，并且主体部分10和盖体20之间通过螺纹件40连接，可以使盖体20与主体部分10密封连接。主体部分10和盖体20组成密封的外壳，外部的水汽难以进入外壳内部。不会影响设于外壳内的传感器组件60的使用寿命及使用效果。
本申请实施例中，传感器组件60是由各部件构成的模块。传感器组件60作为一个整体设于外壳内。传感器组件60与外壳之间相对固定。
一些实施例中，传感器组件60包括支架610、发射传感器620和接收传感器630。发射传感器620用于发射信号。接收传感器630用于接收信号。例如，发射传感器620用于发射光线，接收传感器630用于接收反射的光线。
发射传感器620和接收传感器630分别设于支架610上。发射传感器620和接收传感器630组装在支架610上，形成一个模块。该传感器组件60设于外壳内，与外壳相对固定。
传感器组件60与外壳相对固定的具体方式不限。
一些实施例中，外壳内具有限位结构，传感器组件60装配于外壳内时，限位结构与支架610相作用，将支架610与外壳相对固定。示例性实施例中，外壳内的限位结构，可以是外壳内壁面具有凸棱，凸棱与支架610相作用，对支架610进行限位。将组装有发射传感器620和接收传感器630的支架610装配到主体部分10内，盖体20与主体部分10固定，在凸棱的作用下，传感器组件60被限定在外壳内，传感器组件60与外壳相对固定。设置凸棱，可以避免传感器组件60与外壳的壁面直接接触，在传感器受到冲击时，可以起到一定的缓冲作用，对传感器组件60形成保护。
一些实施例中，支架610与外壳固定连接。示例性实施例中，支架610与盖体20固定连接。支架610与外壳固定连接，例如支架610与盖体20固定连接，可以使传感器组件60与外壳相对固定。
一些实施例中，支架610上具有用于分别设置发射传感器620和接收传感器630的传感器固定位640。在支架610上设置传感器固定位640，可以将发射传感器620和接收传感器630快速装配于支架610上，加快组装速度，并且定位准确，装配精度高。
传感器固定位640的具体形式不限，例如，可以是在支架610上具有特定形状的装配腔来装配接收传感器630和发射传感器620。
一些实施例中，传感器固定位640包括容置槽6410。容置槽6410用于容纳发射传感器620或接收传感器630。通过将发射传感器620或接收传感器630装设于容置槽6410内，可以快速将发射传感器620或接收传感器630装配于支架610的特定位置。定位槽6420的轮廓与发射传感器620或接收传感器630的外形相匹配，可以使发射传感器620或接收传感器630与支架610相对固定。
一些实施例中，传感器固定位640还包括定位槽6420。定位槽6420与容置槽6410连通，定位槽6420用于容纳发射传感器620或接收传感器630上的径向凸部。发射传感器620或接收传感器630具有柱状主体，柱状主体上具有径向凸部。例如，红外LED的尾端具有周向上环形的径向凸部。容置槽6410用于容置柱状主体，定位槽6420用于容纳径向凸部，从而使发射传感器620或接收传感器630与支架610相对固定。
一些实施例中，镜片50与外壳一体注塑成型。示例性实施例中，镜片50与外壳通过双色注塑一体成型。镜片50与外壳一体注塑成型可以提高外壳的密封性能。
一些实施例中，镜片50设于主体部分10上。镜片50与主体部分10一体注塑成型。镜片50设于主体部分10的与开口的一端相对的另一端。设置镜片50一端用于发射和接收信号，因此，传感器装配于电子设备上时，该端露于电子设备外部，更容易接触潮湿环境。主体部分10为一体结构，密封性较高。盖体20一端离潮湿环境较远，进一步降低了水汽侵入外壳的风险。
一些实施例中，主体部分10的另一端具有分隔部110。分隔部110将镜片50分隔为第一镜片510和第二镜片520。主体部分10的设有镜片50的一端设置分隔部110，将镜片50分为第一镜片510和第二镜片520。第一镜片510和第二镜片520可以分别与发射传感器620和接收传感器630对应。
一些实施例中，主体部分10的侧壁上具有至少两个固定凸起120，固定凸起120上具有螺纹孔。盖体20上具有与螺纹孔相对的通孔220。螺纹件40穿过通孔220与螺纹孔螺纹配合将盖体20与主体部分10固定。设置螺纹孔需要有一定的厚度，通过在主体部分10的侧壁上设置固定凸起120，在固定凸起120上开设螺纹孔，可以控制主体部分10的壁厚，节约材料。
一些实施例中，螺纹孔为盲孔。固定凸起120上的螺纹孔可以是通孔220也可以是盲孔。固定凸起120上的螺纹孔为盲孔，可以将螺钉或螺栓等螺纹件40包覆，避免暴露在潮湿环境生锈而损坏。
一些实施例中，固定凸起120设于主体部分10的侧壁的外壁面。设置在外壁面可以使主体部分10内的空间得到有效利用。盖体20上具有与固定凸起120对应的耳部210，通孔220设于耳部210。在盖体20上设置耳部210与固定凸起120相对应，可以节省盖体20的材料。
一些实施例中，主体部分10的开口的一端具有环绕开口的密封槽，或者盖体20上具有密封槽，密封件30嵌于密封槽内。将密封件30嵌于密封槽内可以避免密封件30受力变形或位移而影响密封性能。
一些实施例中，密封件30的表面可以具有连续的凸部。连续的凸 部可以提高密封性能。
一些实施例中，盖体20上设有导线孔230，用于连接传感器组件60的导线70穿过。盖体20上设有密封块70，密封块70用于导线70与盖体20之间的密封。密封块70上具有导线70穿过的孔。密封块70可以设置在导线孔230的孔壁与导线70之间。密封块70也可以设于导线孔230的一端。示例性实施例中，盖体20上具有装配槽240，密封块70设置于装配槽240内。通过过盈配合，密封块70与盖体20之间密封连接。在导线70与导线孔230的孔壁之间设置密封块70，可以对导线70与盖体20之间进行密封，提高外壳整体密封性能。密封块70与盖体20卡接。
本申请实施例中，传感器可以是红外传感器。发射传感器620和接收传感器630分别为红外线发射器和红外线接收器。传感器也可以是激光传感器。传感器的具体类型在此不再一一赘述。
本申请实施例提供了一种清洁设备，其包括上述任一实施例的传感器。
本申请实施例的传感器设于清洁设备上，可以用作悬崖传感器。发射传感器620发射信号(例如红外传感器发射红外线)，经过主体部分10上的镜片50射向地面，然后地面将光束反射通过镜片50进入主体部分10，被接收传感器630接收。如果有悬崖的话，地面高度会发生变化，接收传感器630的接收信号会发生突变或消失，从而判断有悬崖，清洁设备变向或减速停止，避免跌落。
本申请实施例的清洁设备包括扫地机器人、拖地机器人、拖扫机器人和消毒机器人等。
以上描述旨在是说明性的而不是限制性的。例如，上述示例(或其一个或更多方案)可以彼此组合使用，并且考虑这些实施例可以以各种组合或排列彼此组合。本申请的范围应参照所附权利要求以及这些权利要求赋权的等同形式的全部范围来确定。
