Description

用于车辆踏板的电气装置
技术领域
本文的主题总体上涉及车辆踏板的电气装置，更具体地，涉及车辆踏板的照明组件。
背景技术
出于安全和美观目的，车辆的踏板通常包括电气照明装置。通常，踏板沿着车架在前轮舱和后轮舱之间以及车门开口下方延伸，以提供台阶来帮助乘客进入或退出车辆。为了功能和装饰目的，照明组件通常与踏板联接。例如，照明组件可以照亮踏板的表面和/或踏板下方的地面上的绊倒或安全隐患。在另一示例中，照明组件可以通过照亮踏板或车辆上的标记或徽标来增强车辆的外观。
通常，为了安全和美观目的，需要多个照明组件来提供照明，和/或在多个位置提供照明。然而，多个照明组件导致成本、组装和安装的增加。因此，要解决的问题是需要最大化照明组件的照明属性，同时最小化成本、组装和安装。
发明内容
该问题通过一种用于车辆的电气装置来解决，其包括具有显示器安装座和透镜筒的壳体。上部光源附接到壳体的显示器安装座以发射上部光。导光元件安装到壳体的显示器安装座且与上部光源对准，以接收上部光并在第一发射方向上引导出射光。显示器附接至壳体的显示器安装座且与导光元件对准以接收出射光来照明显示器。下部光源附接至壳体的透镜筒以发射下部光。透镜组件附接至壳体的透镜筒。透镜组件配置为从下部光源接收下部光并在不同于第一发射方向的第二发射方向上引导出射光。
附图说明
现在将通过示例参考附图描述本发明，其中：
图1示出了根据实施例的电气装置的局部分解透视图；
图2示出了根据实施例的电气装置的透视截面图；以及
图3示出了根据实施例的电气装置的分解透视图。
具体实施方式
本文公开的一个或多个实施例包括一种用于安装在车辆的踏板中的电气装置，该电气装置配置为提供用于在第一方向上发射漫射光图案以使显示器背光的上部照明组件。例如，上部光源可以附接至显示器安装座并与导光元件的端部对准。导光元件从上部光源接收入射光并引导出射光以使显示器背光。电气装置还包括下部照明组件，其配置为在第二方向上发射光通过透镜组件成为聚焦光图案以照亮表面。例如，透镜组件可以包括成嵌套布置的准直仪、辅助透镜和下部构件，其衍射和/或折射光以射出透镜组件作为聚焦光图案中的出射光。
图1示出了根据实施例的电气装置100的透视截面图。电气装置100包括具有上部104和下部106的壳体102。如本文所使用的，诸如“上部”、“下部”、“顶部”、“底部”、“前部”、“后部”、“左”和“右”的相对或空间术语仅用于区分所引用的元件，并且不一定需要电气装置100相对于电气装置100的周围环境的特定位置或取向。壳体102配置为插入车辆(未示出)的踏板110的腔或凹部108中。在替代实施例中，壳体102可以插入车辆上任何位置的任何凹部中，例如保险杠、门槛、扰流板等。
图2示出了根据实施例的电气装置的透视截面图。图3示出了根据实施例的电气装置的分解透视图。壳体102的上部104是显示器安装座112，其配置为安装上部照明组件114和显示器116。显示器安装座112基本上是平坦的且为具有上表面118、下表面120和外周边缘122的矩形形状。多个引导凸部124从显示器安装座112的边缘向上延伸。在图1-3的实施例中，四个引导凸部124围绕边缘122等距地间隔。引导凸部124配置为使显示器116与显示器安装座112对准。在替代实施例中，可以使用任何数量和布置的引导凸部124以使显示器116与显示器安装座112对准。
多个保持构件126从显示器安装座112的边缘122向上延伸。保持构件126配置为将显示器116固定至显示器安装座112。在图1的实施例中，两个保持构件126在相对侧围绕显示器安装座112的中点设置。在替代实施例中，可以使用任何数量和配置的保持构件126将显示器116固定到显示器安装座112。每个保持构件126包括上部成角度的部分128，其配置为在成角度的部分128与显示器安装座112的上表面118之间限定凹陷区域130。凹陷区域130配置为接收显示器116的一部分以将显示器116固定至显示器安装座112。当将显示器112附接至显示器安装座116时，显示器116向下压在成角度的部分128上以使成角度的部分128向外偏转。当显示器116位于凹陷区域内时，成角度的部分128返回默认位置，使得成角度的部分128位于显示器116的一部分上方以进行固定。
显示器安装座112包括从上表面118向上延伸的肋132。肋132配置为与显示器116配合，如下文进一步描述的。
上部照明组件114包括上部光源134，其安装至显示器安装座112的上表面118。导光元件136安装至显示器安装座112的上表面118且与设置在导光元件136的端部138附近的上部光源134对准。在替代实施例中，第二上部光源设置在导光元件的端部附近，与第一上部光源134相对。导光元件136大致为矩形的棱柱，其配置为从上部光源134接收入射光并在第一发射方向140上引导出射光。从上部光源134发射的光进入导光元件136的端部138且以漫射光图案被向上引导穿过导光元件138的顶表面142。来自导光元件138的出射光使显示器116背光。导光元件136包括诸如塑料、玻璃、丙烯酸、二氧化硅、聚碳酸酯等的材料。导光元件136由诸如玻璃、丙烯酸、聚丙烯、聚碳酸酯或其他聚合物的透光材料组成。
上部光源134包括安装到基板(例如印刷电路板(PCB)144)的发光装置。上部光源134可以是发光二极管(LED)。可选地，上部光源134可以是发射单色白光的单色LED灯。替代地，上部光源134可以是三色红绿蓝(RGB LED，其配置为能够发射红光、绿光、蓝光，和/或它们的组合以产生许多不同的颜色和光影。在替代实施例中，代替LED，上部光源138可以是白炽灯泡、紧凑型荧光灯(CFL)灯泡、氙气灯泡、卤素灯泡等。上部光源134配置为向导光元件136发射光。
上部光源134可操作地联接到光引擎。光引擎包括驱动器、控制器、诸如电池的电源，和/或相关联的电路，用于控制由光源134产生的光的光学特性。驱动器、控制器、电源，和/或相关电路中的至少一些可以嵌入或以其他方式包含在(PCB)上。光引擎经由电引线144和/或电线接收电力和/或控制信号，该电引线144和/或电线远程地延伸以连接到车辆中的远程电源和/或控制器。光引擎可以结合到操作上部光源134的开关。尽管在所示实施例中，一个上部光源134与每个光引擎相关联，但是在其他实施例中，单个光引擎可以控制多个光源的操作。
显示器116基本上是平坦的且为具有顶表面150、底表面152和周边边缘154的矩形形状。显示器116配置为具有一定厚度，使得显示器116的边缘154插入保持构件126的凹部128中以固定至显示器安装座112。底表面152配置为限定通道156，以至少部分地包围导光元件136和上部光源134。底表面152还配置为限定用于电线160的导管158和用于接收肋132的周向凹槽162。诸如粘合剂的结合材料165设置在凹槽162内，以将显示器116固定到显示器安装座112的上表面118。在其他实施例中，显示器116可以使用任何合适的材料或工艺(包括但不限于胶带、焊接、紧固件等)固定至显示器安装座112。
显示器116包括沿通道156的顶部延伸的装饰元件，例如防擦板164。防擦板164包括与导光元件136的顶表面142对准的开口166。开口166可以被配置为期望的标记，例如徽标、设计、字母、数字、符号或其他标记。来自导光元件136的出射光通过开口166发射，从而照亮标记。
壳体102的下部106包括基本上圆柱形的筒170，其从显示器安装座112的下表面120向下延伸。筒170配置为接收下部光源172和透镜组件174。下部光源172固定至透镜组件174的顶部且定位为通过透镜组件174发射光并以聚焦光图案176引导出射光到表面177上。
下部光源172包括安装到基板178的发光装置。下部光源172可以是发光二极管(LED)。可选地，下部光源172可以是发射单色白光的单色LED灯。替代地，下部光源172可以是三色红绿蓝(RGB LED，其配置为能够发射红光、绿光、蓝光，和/或它们的组合以产生许多不同的颜色和光影。在替代实施例中，代替LED，下部光源172可以是白炽灯泡、紧凑型荧光灯(CFL)灯泡等。上部光源#配置为向导光元件136发射光。
下部光源172可操作地联接到光引擎。光引擎包括驱动器、控制器、诸如电池的电源，和/或相关联的电路，用于控制由下部光源172产生的光的光学特性。驱动器、控制器、电源，和/或相关电路中的至少一些可以嵌入或以其他方式包含在(PCB)上。光引擎经由电引线和/或电线接收电力和/或控制信号，该电引线和/或电线远程地延伸以连接到车辆中的远程电源和/或控制器。光引擎可以结合到操作下部光源172的开关。尽管在所示实施例中，一个下部光源172与每个光引擎相关联，但是在其他实施例中，单个光引擎可以控制多个光源的操作。例如，单个光引擎可以控制下部光源172和上部光源134的操作。
透镜组件174包括成嵌套布置的准直仪180、辅助透镜182和下部构件184，其插入筒170中。透镜组件174还包括设置在筒170的端部中的透镜186。
准直仪180包括圆柱形部分188，其在上端处具有外缘190，使得准直仪可以嵌套在辅助透镜182内。准直仪180配置使得来自下部光源172的入射光被衍射和折射以形成作为射出到辅助透镜182的出射光的准直光束。
辅助透镜182包括圆柱形部分183，其在上端处具有外缘185，使得辅助透镜可以嵌套在下部构件184内。辅助透镜修改通过透镜组件174的光的属性，例如焦距。在替代实施例中，辅助透镜不包含在透镜组件174中。
下部构件184包括圆柱形部分192，其在上端处具有外缘194和沉孔196。下部构件184还包括具有孔口200的底表面198。孔口200配置为从准直仪180接收入射光并通过孔口200发射光以形成预定图像或标记。
设置在筒170的端部中的透镜186从下部构件184接收出射光并在第二方向202上将出射光发射到表面177上。从下部构件184通过透镜186的出射光被衍射和/或折射，并以聚焦光图案作为出射光从透镜186离开或射出。透镜186由诸如玻璃或丙烯酸的透光材料构成。透镜186可以是透光和透明的，或者至少是半透明的，以允许光的透射。
