本发明技术方案中，底座200的定位部220用来定位安装热释电传感组件300，定位部220上设置有相对基板210倾斜设置的定位斜面221，热释电传感组件300安装时，被定位斜面221倾斜支撑，相对底座200倾斜的安装到所述底座200上；此时，热释电传感组件300的正面和背面分别朝向罩状聚光器120的不同位置，由于热释电传感器310位于热释电传感组件300的正面，因此罩状聚光器120射向热释电传感组件300的背面的光线，不会被热释电传感器310接收，如此，仅仅热释电传感组件300的正面对应的感测区域的能够被热释电传感器310感测；因而对应的热释电红外传感装置900能够定向感测热释电传感组件300正面的感测区域，而不会对热释电传感组件300背面对应的非感测区域进行不必要的感测，从而可以更准确的对部分区域进行定向感测，得到较精确的感测结果，适应挂墙或靠墙设置的电器的感测需要；同时，将罩状聚光器120划分成透镜区121和非透镜区122，仅仅透镜区121对应的感测区域的能够被热释电传感器310感测，因而使用该上盖组件100的热释电红外传感装置900能够定向感测透镜区121对应的感测区域，而不会对非透镜区122对应的非感测区域进行不必要的感测，从而可以更准确的对部分区域进行定向感测，得到较精确的感测结果，进一步适应挂墙或靠墙设置的电器的感测需要。
其中，所述定位斜面221和所述基板210的夹角大小，根据热释电红外传感装置900安装电器中时，该基板210和竖直方向的夹角以及电器对应的感测范围来确定，例如该热释电红外传感装置900设计为距离电器1m~8m的范围为感测区域时，所述定位斜面221和所述基板210的夹角大小与所述基板210和竖直方向的夹角大小的差是-5~0°，优选所述定位斜面221和所述基板210的夹角与所述基板210和竖直方向的夹角大小相等。感测范围距离电器越近则所述定位斜面221和所述基板210的夹角与所述基板210和竖直方向的夹角的差越小。实际操作时，根据实际情况进行合理设置即可。
所述罩状聚光器120的边沿与所述环形座110的上沿密封连接，如此能够防止水、灰尘等进入热释电红外传感装置900中，从而延长该热释电红外传感装置900的使用寿命。为了达到较好的密封效果，该罩状聚光器120与环形座110可以一体成型，然后在罩状聚光器120的透镜区121内侧形成图案，即可在罩状聚光器120的透镜区121形成单元透镜123。
透镜区121的作用是将光线进行聚焦，增大热释电传感器310的感测范围，同时能够将感测区域分为若干个明区和暗区，使进入感测区域的移动物体能以温度变化的形式在热释电传感器310上产生变化热释红外信号。当热释电红外传感装置900设有一个热释电传感器310时，所有的单元透镜123的焦点相同，均落到该热释电传感器310上，从而将各个方向的光线都聚焦到热释电传感器310上。请参阅图3至图5，为了更准确的进行分区定位，热释电红外传感装置900会设置多个热释电传感器310，此时，需要在所述透镜区121对应设置多组透镜组，每一组所述透镜组包括至少一个所述单元透镜123，同一组所述透镜组中的所述单元透镜123的焦点相同；一组透镜组的单元透镜123的焦点落到一个热释电传感器310上，将射到单元透镜123上的光线折射到对应的热释电传感器310中，如此能够将感测区域进行分区，实现分区定位感测，达到更精确的感测效果。
透镜区121需要允许光线通过，因此通常设置所述罩状聚光器120的材质为透光塑料或玻璃，具体可以是透明的PE（聚乙烯）、PP（聚丙烯）等聚烯烃塑料，也可以是增加少许浅色（白色等）填料的透光但不透明的塑料。当然，为了得到更精确的感测结果，可以设置非透镜区122是不透光的，如此，能够进一步屏蔽其他方向射到罩状聚光器120上的光，对应的热释电红外传感装置900可以更准确的对部分区域进行定向感测。由于罩状聚光器120的材质强度较低，遭受外力容易破损，为了解决这个问题，请参阅图2、图3、图10以及图11，在本实施例中，所述热释电红外传感装置900还包括支撑件400，所述支撑件400设于所述上盖组件100的内侧，所述支撑件400包括环形安装部410和支撑板420，所述支撑板420的边沿与环形安装部410相连接，所述环形安装部410安装于所述基板210上；所述支撑板420呈盖状设置，所述支撑板420贴靠所述罩状聚光器120并对所述罩状聚光器120进行支撑，为了避免遮挡感测区域传递过来的光线，支撑件400设置了透光窗421，光线穿过透光窗421射到热释电传感器310上，实现对感测区域的信号采集，从而在对罩状聚光器120进行支撑时不影响对感测区域进行感测；由于支撑板420的强度比较强，在罩状聚光器120受到外力时，外力会传递到支撑板420上，支撑板420不易损坏变形，因此与支撑板420贴靠的罩状聚光器120也不易变形，通支撑板420的支撑可以有效提高罩状聚光器120承受外力的能力，改善罩状聚光器120受外力破损的情况。透光窗421开设的位置根据感测区域设定，感测区域越小透光窗421可以对应开设得越小，因此该支撑件400尤其适用于需要对部分区域进行定向感测的热释电红外传感装置900，例如应用于挂墙或靠墙设置的电器（空调器室内机、壁灯、冰箱等）中的热释电红外传感装置900，需要仅对电器前方的区域进行感测，此时透光窗421面积较小，而支撑板420与聚光器贴靠的部分面积较大，支撑效果更佳。
为了更准确的进行分区定位，热释电红外传感装置900会设置多个热释电传感器310，此时，为了避免一个热释电传感器310的感测区域射来的光线被另一热释电传感器310接收而造成干扰，请参阅图3、图9和图11，在本实施例中，所述支撑件400还包括隔板430，所述隔板430对应所述透镜组的位置设于所述透光窗421中以对所述透光窗421进行分隔，所述隔板430背向所述环形安装部410的边沿的形状与所述罩状聚光器120的形状相匹配，且抵靠所述罩状聚光器120的内侧，所述隔板430朝向所述环形安装部410的边沿抵靠所述电路板320；从而将每个热释电传感器310隔离在独立的区域内，相互之间不会干扰，如此能够将感测区域进行分区，实现分区定位感测，达到更精确的感测效果；同时隔板430背向所述环形安装部410的边沿还能够对罩状聚光器120进行支撑，辅助支撑板420进行支撑，达到更好的支撑效果，进一步提高罩状聚光器120耐冲击性，避免罩状聚光器120受力变形。隔板430的具体数量、设置情况需要根据透镜组的情况进行选取，例如当设有N个透镜组时，则需要设置N-1个隔板430，每一隔板430位于相邻两个透镜组之间；在本实施例中，热释电传感组件300设有两个热释电传感器310，透镜区121设有对称设置的两组透镜组，隔板430与所述环形安装部410所在的平面相垂直，所述隔板430的数量为一个，且所述隔板430设于所述透光窗421的中心处，以将所述透光窗421分隔成大小相同的两个部分。如此，两个热释电传感器310可以分别独自接收透光窗421的一个部分射来的光线，将整个感测区域分为三个子区域（两个热释电传感器310各自独立感测区域，以及两个热释电传感器310重合的感测区域），实现分三个区定位感测，达到更精确的感测效果。
该隔板430可以是固定的，也可以是可移动安装，在本实施例中，为了保证支撑件400的强度，所述环形安装部410、所述支撑板420和所述隔板430一体成型。支撑件400的材料可以选取强度较高的硬质塑料，通过注塑成型，如此能够进一步提高支撑件400的强度，并且提高支撑件400的生产效率。
支撑板420不但能够对罩状聚光器120进行支撑，还能够辅助热释电传感组件300的安装，请参阅图10，如本实施例所示，所述支撑板420的内侧设有若干用以压紧所述电路板320的凸筋422，至少一个所述凸筋422上设有用于容置所述电路板320边沿的限位槽423。凸筋422从上方压紧电路板320避免其向远离底座200的方向移动或脱出；其中凸筋422的数量可以根据压紧需要进行选取，在本实施例中，设置了三条凸筋422，中间的凸筋422上开设有限位槽423，当支撑件400安装到热释电红外传感装置900中时，所述电路板320的上边沿伸入限位槽423中，能防止凸筋422与电路板320打滑，同时能够限制电路板320在限位槽423宽度方向的晃动，中间的凸筋422对应电路板320的上边的中部设置，另外两个凸筋422对称设置，如此，能够避免电路板320歪斜，达到更均匀的压紧效果，两侧的两个凸筋422也可以设置限位槽、限位缺口等进行限位，在本实施例中位于两侧的两个凸筋422设置了限位缺口，同样能够达到防滑、限位的效果，在此不再赘述。凸筋422与隔板430可以连接形成一个整体，从而提高支撑件400的整体强度。
为了保证支撑件400能够可靠的安装到底座200上，底座200一般设置有与环形安装部410配合的结构，请参阅图2、图7、图8以及图10，在本实施例中，所述基板210上开设有容置槽211，所述定位部220设于所述容置槽211中，所述环形安装部410背向所述支撑板420的一侧凸设有一圈环形凸起411，所述环形凸起411插入所述容置槽211中，以将所述支撑件400安装到所述底座200上。利用环形凸起411与容置槽211插接，将支撑件400安装到底座200上，安装操作方便快捷，同时，底座200与上盖组件100配合时，能够合围形成一个较大的容置空间，方便内部元件的安装和排布。为了对支撑件400进行准确定位，请参阅图2和图3，在本实施例中，所述基板210上凸设有防呆凸起212，所述环形安装部410上设有防呆槽412，所述防呆凸起212插入所述防呆槽412中，以对所述支撑件400进行定位；如此，该支撑件400能够快速准确的安装到底座200上，有利于提高对应的热释电红外传感装置900的生产效率。
定位部220用于定位支撑热释电传感组件300，定位斜面221主要对电路板320进行定为支撑，请参阅图6至图8，在本发明一实施例中，所述定位部220包括两个限位板222，所述限位板222的板面相对所述基板210垂直设置，两个所述限位板222之间具有间隙，每一所述限位板222朝向另一所述限位板222的板面上设有一个斜槽223，所述斜槽223自所述限位板222的自由端向所述基板210延伸，所述斜槽223的侧壁构成所述定位斜面221，所述电路板320的两个边沿分别插入两个所述斜槽223中，以将所述热释电传感组件300倾斜安装到所述底座200上。具体的，斜槽223具有两个槽口，一个槽口位于限位板222的自由端，另一个槽口位于限位板222的板面，如此，斜槽223可以供电路板320的边沿插入，其中位于电路板320下方的斜面即为定位斜面221，两个斜槽223分别容置电路板320的两侧边沿，对电路板320进行定位支撑，实现热释电传感组件300的可靠安装，同时两个限位板222分别贴靠热释电传感组件300的两侧防止热释电传感组件300在一个限位板222指向另一限位板222的方向上晃动，设置所述斜槽223的宽度R比所述电路板320边沿的厚度大0.02-0.07mm（优选0.05mm），防止热释电传感组件300在斜槽223宽度的方向来回晃动，如此可以将热释电传感组件300牢固的安装到底座200上，从而能够避免安装不牢时热释电传感组件300晃动影响感测效果。因为所述斜槽223的宽度R和所述电路板320边沿的厚度比较接近，插入时对准困难，为了使得热释电传感组件300安装时能够更顺畅，请那样图8，在本实施例中，所述斜槽223位于所述限位板222自由端的槽口设有导向段224，所述导向段224的宽度K自远离所述限位板222自由端的一端向靠近所述限位板222自由端的一端渐扩设置；电路板320插入斜槽223时，一开始不用完全对准，在插入斜槽223的过程中导向段224对电路板320导向，最终顺利的插入斜槽223内。
定位部220只要能够对热释电传感组件300进行定位安装即可，其实现方式有很多种，请参阅图9，例如在本发明另一实施例中，本实施例中底座200’的定位部220’包括安装板225，所述安装板225的板面相对所述基板210倾斜设置，所述安装板225的背向所述基板210的板面构成所述定位斜面221’；热释电传感组件300进行安装时，电路板320的背面贴靠安装板225的背向基板210的板面，电路板320与安装板225之间通过螺钉、胶粘、卡扣等结构固定，如此同样能够支撑热释电传感组件300倾斜安装。其他支撑热释电传感组件300倾斜安装的结构也可以应用于本发明的定位部220中，在此不做限定。
热释电传感组件300一般通过导线与外部电路进行电性连接，为了避免导线杂乱，请参阅图6或图9，在该些实施例中，所述定位部220还包括辅助定位板226，所述辅助定位板226上开设有用于定位安装所述热释电传感组件300的导线的走线槽227。热释电传感组件300安装到位后，导线穿过走线槽227走线，能够避免导线杂乱。
透镜区121与非透镜区122的位置、形状和大小需要根据实际情况选取，原则是，透镜区121根据挂墙或靠墙设置的电器的正前方的感测区域以及安装到位后热释电传感器310的位置进行设置。请参阅图4和图5，在本实施例中，优选所述罩状聚光器120呈半球形设置，两条自所述罩状聚光器120的中心向所述罩状聚光器120边沿延伸的弧线段将所述罩状聚光器120划分形成所述透镜区121和所述非透镜区122。将罩状聚光器120设置呈半球形，可以增大感测角度；其中，每一条弧线段都是经过罩状聚光器120中心的球面大圆的弧线段，使得该透镜区121和非透镜区122俯视观察时均呈扇形设置，如此，能够达到更均匀的折射效果，避免感测区域不对称的情况，从而更有利于精确感测，为了适应挂墙或靠墙设置的电器的感测需要，对电器前方180°左右的范围均进行感测，优选设置所述透镜区121的面积大于所述非透镜区122的面积，此时透镜区121对应的感测范围能够完全覆盖电器前方，从而能够进行全面感测。
为了折射不同方向射到透镜区121的光线，需要对应每个位置设置不同的透镜纹路，因此需要在所述透镜区121设置若干个单元透镜123，该些单元透镜123的具体分布情况根据感测区域以及安装到位后热释电传感器310的位置进行设置，请参阅图4和图5，在本实施例中，所述透镜区121由多个经过所述罩状聚光器120的中心的球面大圆和多个与所述罩状聚光器120的边沿平行的球面小圆划分成网格状，每一网格中设有一个所述单元透镜123，每一所述单元透镜123的形状与对应所述网格的形状相同。其中，球面大圆定义为球面上圆心与球心重合的圆，球面小圆的定义为球面和不通过球心的平面的交线，通过球面大圆可以将透镜区121划分为多个沿左右方向排布的区域，其对应到感测区域水平方向上的各个位置，通过球面小圆可以将透镜区121划分为多个沿上下方向排布的区域，其对应到感测区域竖直方向上的各个位置，如此划分后，每一个网格处即对应感测区域的一个确定的位置，因此当单元透镜123位于该网格中并对应网格的形状进行设置时，对应位置射出的光线能够经过单元透镜123准确的折射到相应的热释电传感器310上，因而能够达到非常准确的感测效果。
上盖组件100安装到底座200上时，需要在上盖组件100和底座200上设置互相配合的安装结构，请参阅图1和图2，在本实施例中，所述基板210上设有卡合安装部213，所述环形座110设有背向罩状聚光器120延伸的凸耳111，所述凸耳111上设有开口112，所述卡合安装部213伸入所述开口112中与所述开口112卡合连接，以将所述上盖组件100安装到所述底座200上。通过凸耳111与卡合安装部213的卡合，实现了上盖组件100与底座200的安装，卡合安装时，操作快捷简单，能够节约安装时间。
传统的热释电传感器310的探测面与电路板320之间是平行设置的，这导致热释电传感器310难以接收平行于电路板320或者与电路板320夹角较小于的光线，导致感测范围较小；请参阅图12至图14，本实施例中，为了解决这个问题，所述热释电传感组件300还包括安装支架330，所述安装支架330安装于所述电路板320上，所述安装支架330中部向远离所述电路板320的方向凸出，以使所述安装支架330具有至少两个朝向不同的安装面331，所述安装面331上均安装有热释电传感器310。安装支架330中部向远离所述电路板320的方向凸出，以使所述安装支架330具有至少两个朝向不同的安装面331，并且安装面331相对电路板320倾斜，因此安装在安装面331上的热释电传感器310的感测面也相对电路板320倾斜，能够接收平行于电路板320或者与电路板320夹角较小于的光线；同时，每个安装面331上均设有热释电传感器310，每个热释电传感器310朝向不同，对应的感测区域也不同，朝向电路板320的光线也能够被对应热释电传感器310感测，如此，热释电传感器310能够接收朝向电路板320的光线以及平行于电路板320或者与电路板320夹角较小于的光线，大大增加了对应的热释电传感组件300的感测范围。
安装支架330可以设置成多种结构，只要保证形成倾斜的安装面331即可达到相应效果，请参阅图13和图14，在本实施例中，所述安装支架330呈板状，所述安装支架330的中部向远离所述电路板320的方向弯折以具有两个朝向不同的所述安装面331。此时，安装支架330结构比较简单，方便成型，从侧面观察，安装支架330大致围成一个梯形或者三角形，分别安装到两个安装面331上的两个热释电传感器310朝向两个不同的方向，各种感测对应区域的信号。两个安装面331相对倾斜，两者的夹角角度根据需要感测的区域而定，当两者感测区域需要重合一定范围时，两个安装面331之间的夹角α（大于180°）一般设置得较小，当两者感测区域需要相对独立时，两个安装面331之间的夹角α一般设置得较大，在本实施例中，设置两个所述安装面331之间的夹角α为230-250°，优选240°（即安装支架330弯折110-130°，优选120°，此时安装面331与电路板320之间的夹角β为120°），如此两个热释电传感器310感测区域重合一定范围，从而将整个感测区域分为三个子区域（两个热释电传感器310各自独立感测区域，以及两个热释电传感器310重合的感测区域），实现分三个区定位感测，达到更精确的感测效果，具体的，两个所述安装面331之间的夹角α为240°，电路板320正面朝向感测区域时，两侧的独立扇形检测区域圆心角均为75±10°，中间扇形检测区域圆心角为30±10°；水平检测角度180±10°，检测范围0~8米；人体移动分三个区检测的准确率≥90%。
为了热释电传感器310安装更牢固且安装位置更准确，请参阅图13和图14，在本实施例中，所述安装面331上开设有安装槽332，所述安装槽332的槽底设有让位通孔333，所述热释电传感器310安装于所述安装槽332中且所述热释电传感器310的接线脚311穿过所述让位通孔333与所述电路板320连接。热释电传感器310容置于安装槽332中，安装槽332位置根据探测范围的需要进行选取，例如在本实施例中，需要两个热释电传感器310的感测区域大部分重叠因此设置两个安装槽332的位置比较靠近，反之，如果只需要两个热释电传感器310的感测区域少部分重叠则可以适当增加两个安装槽332之间的距离。安装槽332的形状与热释电传感器310的形状相同，安装槽332的槽底设置了让位通孔333，该让位通孔333供热释电传感器310的接线脚311穿过，从而与所述电路板320连接，实现热释电传感器310与电路板320的电性连接，方便热释电传感器310的接线。
由于安装支架330是弯折设置的，容易安装不稳，为了解决这个问题，请参阅图13和图14，在本实施例中，所述安装支架330朝向所述电路板320的板面上设有支撑脚334，所述支撑脚334远离所述安装支架330的一端贴靠所述电路板320，支撑脚334对安装支架330进行支撑，有利于安装支架330稳固安装，同时，所述支撑脚334位于所述安装槽332背面，所述让位通孔333贯穿所述支撑脚334设置，如此，热释电传感器310的接线脚311可以直接通过让位通孔333贯穿支撑脚334与支撑脚334下方的电路板320进行连接，支撑脚334能够帮助接线脚311对准电路板320还能够对接线脚311进行保护。
安装支架330可以通过卡合、螺钉、胶粘等方式安装到电路板320上，请参阅图14，在本实施例中，所述安装支架330设有卡扣335，由于该安装支架330为弯折的板状，因此卡扣335设置在所述安装支架330的两端，所述电路板320上对应所述卡扣335的位置设有卡槽321，每一所述卡扣335自所述电路板320正面穿过对应的所述卡槽321并扣持于所述电路板320背面，以将所述安装支架330安装于所述电路板320上。通过卡扣335卡合拆装时，操作方便快捷，能够简化安装板225的安装过程，同时电路板320上设置与接线脚311对接的通孔，能够在安装安装板225的同时，实现接线脚311的接线，进一步提高热释电传感组件300的装配效率。
热释电传感组件300需要跟外部电路进行连接，因此，该电路板320上设有数个电连接器的母头322，将与外部电路连通的公头插入母头322中，即可实现热释电传感组件300与外部电路的连通，连线方便快捷。
请参阅图15，并结合图1至图3进行理解，本发明还提出一种电器，其包括电器本体800以及热释电红外传感装置900，该热释电红外传感装置900的具体结构参照上述实施例，由于本电器采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，所述热释电红外传感装置900安装于所述电器本体800上，所述罩状聚光器120自所述电器本体800中露出且所述透镜区121朝向所述电器对应的待感测区域。该热释电红外传感装置900设计为距离电器本体1m~8m的范围为感测区域，所述定位斜面221和所述基板210的夹角大小与所述基板210和竖直方向的夹角大小的差是-5~0°，优选所述定位斜面221和所述基板210的夹角与所述基板210和竖直方向的夹角大小相等。感测范围距离电器越近则所述定位斜面221和所述基板210的夹角与所述基板210和竖直方向的夹角的差越小。
该电器可以是挂墙或靠墙设置的电器，具体可以是空调器室内机、壁灯、冰箱等，在本实施例中，所述电器为空调器室内机。
应当说明的是，本发明的各个实施例的技术方案可以相互结合，但是必须是以本领域的技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当人认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
