Description

多向发光的行驶状态指示装置 技术领域
本发明涉及动平衡车技术领域，特别涉及一种安装在车体内部且能实现多向发光的行驶状态指示装置。
背景技术
随着智能技术的发展，动平衡车成为了一种新兴的短途代步的交通工具。动平衡车由于其自身的特点，大多只能在自行车道或非机动车道行驶。由于动平衡车并没有设置有后视镜，因此只能依靠声音或光源来提示行驶在其后方的行人或车辆。由于在嘈杂的环境下，声音提示往往起不到应有的提示作用，因此目前的动平衡车大多采用光源提示方式，通过在动平衡车的后部安装相应的指示灯来进行提示。
然而，目前动平衡车的指示灯，例如起到刹车提醒的刹车灯，通常都是直接暴露在动平衡车的外表面，也有通过透明镜片将其遮盖的方案。当指示灯亮起时，其光线会直接照射到动平衡车行驶的后方，对跟随动平衡车的交通工具及行人起到警示作用，即通过单向向后发光的方式进行发光。但是，这种单向向后发光的方案存在以下问题：
(1)现有的方案指示灯普遍为点光源，通过空气后后方单向传送。当动平衡车在强光的环境中行驶时，指示灯的光源会受环境光源的影响而变弱。此时跟随动平衡车的驾驶员或行人将很难看到刹车灯是否亮起，从而发生危险。
(2)点光源通过空气传送直接照射到后方，其光线都是直接照射到跟随的车辆或行人，易刺激跟随动平衡车的驾驶员或行人的眼睛，尤其是紧急刹车时，指示灯亮起的强度会变大，这样高强度的光源非常容易导致跟随动平衡车的驾驶员或行人的眼睛不舒服，从而发生的危险。
(3)此外，现有的动平衡车的用于刹车提醒的刹车灯不能显示出刹车强度的大小，当动平衡车采取紧急刹车时，后面的车辆或行人在突发时间内很难判断其刹车强度，特别是给在某些场合不能保持车距的车辆或造成极大威胁，很容易造成事故的发生。
(4)再者，动平衡车的体积通常不会很大，一旦在其尾部安装了刹车灯，就无空间再装尾灯和转向灯，即现有的指示灯功能比较单一。而尾灯和转向灯同样也是交通工具的重要安全部件，缺少任何一个都会有安全隐患。
因此，迫切期待提供一种能够实现指示灯发出非常柔和的光线且同时能够作为刹车灯、转向灯和尾灯以及能够使得后面的车辆或行人准确判断刹车强度 的多向发光的行驶状态指示装置的出现。
发明内容
为了解决现有技术的问题，本发明的实施例提供一种能够多向发光以提供柔和光线且能同时实现刹车提醒、转向提醒和正常行驶提示的多向发光的行驶状态指示装置。
本发明的实施例采用的技术方案如下：
在本发明的一实施例中，提供了一种多向发光的行驶状态指示装置，安装在动平衡车的车体上，包括灯体、固定件、导光板和控制器，其中所述固定件安装在所述车体的后部，所述灯体以照射方向朝向地面的方式安装在所述固定件的内部，所述导光板固定安装在所述固定件上且位于所述灯体的下方，所述控制器安装在车体的内部，根据所述动平衡车的行驶状态控制所述灯体的发光状态。
在一可实施方式中，所述动平衡车处于刹车模式时，所述控制器控制所述灯体呈现第一发光状态；所述动平衡车处于转向模式时，所述控制器控制所述灯体呈现第二发光状态；所述动平衡车处于正常行驶模式时，所述控制器控制所述灯体呈现第三发光状态。
在一可实施方式中，所述第一发光状态、所述第二发光状态和所述第三发光状态为不同的发光状态。
在一可实施方式中，所述灯体对称地设置在所述固定件的两侧。
在一可实施方式中，所述灯体由若干个发光LED并联形成。
在一可实施方式中，所述控制器独立控制每个发光LED。
在一可实施方式中，所述固定件内部形成有卡槽，所述灯体安装在所述卡槽中。
在一可实施方式中，所述灯体通过粘接剂固定在所述卡槽中。
在一可实施方式中，所述固定件为装饰条。
在一可实施方式中，所述导光板由塑料材质或玻璃材质形成。
本发明实施例提供的技术方案的有益效果为：
(1)由于将灯体设置在固定件的内部，而不是暴露在固定件的外部，且以朝向地面发光的方式安装在固定件的内部，从而使得发出的光可通过车体的折射和反射出来，使得发出的光线非常柔和；
(2)灯体由多个发光LED形成，且每个发光LED都是独立控制的，在车辆转向、刹车和正常行驶状态下，可分别控制每个发光LED的发光状态，以使得灯体呈现不同的发光状态，能够作为刹车灯、转向灯和尾灯使用；
(3)由于在灯体下方安装有具有导光性能的导光板，从而灯体发出的点光源可通过导光板的折射和反射而转换为面光源，同时，由于灯体向地面照射，地面也会形成一团光斑，这样，地面的光斑和导光板所传导的光会交织在一起一体形成一团光晕，即使在强光的环境下，跟随在动平衡车后方的驾驶员或行人都能很清晰的看到动平衡车所给出的刹车警示，同时也不会造成对眼部的刺激，能够有效的避免危险。
附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例中使用的附图作一简单地介绍，显而易见地，下面所列附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明的实施例的多向发光的行驶状态指示装置安装在在车体上的侧面剖视示意图。
具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本发明的实施例的多向发光的行驶状态指示装置可安装在动平衡车上，尤其是双轮动平衡车上。但是并不仅限于动平衡车上，也可安装在其他车体上。动平衡车具体结构为本领域熟知的结构，在此省略详细介绍。
图1为本发明的实施例的多向发光的行驶状态指示装置安装在在车体上的结构剖视图。如图1所示，本发明的实施例的多向发光的行驶状态指示装置可包括灯体1、固定件2和控制器4，其中控制器4安装在车体4的内部，与灯体1连接，固定件2安装在车体4的后部。
本发明的实施例与现有技术的一个不同点在于，灯体1并不是直接暴露在车体外部，而是以照射方向朝向地面的方式安装在固定件2的内部空间中，即灯体1是隐藏在车体内部。这种将车灯隐藏在车体内部的结构，车灯的光线会通过车体的折射和反射出来，从而使得光线非常柔和。在动平衡车为双轮的情况下，灯体1对称地设置在车体3的后部两侧。
此外，本发明的实施例与现有技术的另一个不同点在于，在灯体2的下方安装有具有导光性能的导光板5。导光板5向下突出安装在固定件2的下方，将 灯体1包围在固定件2的容纳空间中，这样，固定件2与导光板5共同形成一个封闭空间。当灯体1发光时，位于其下方的导光板5会将灯体1发出的点光源通过折射和反射而直接转换为面光源，此时整个导光板5会变成一个面光源。同时，由于灯体1的照射方向是朝向地面，所以地面也会形成一团光斑。此时，地面上的光斑和导光板5所传导的光一体形成一团光晕，如此，即使在强光的环境下，跟随在动平衡车后方的驾驶员或行人也能很清晰的看到动平衡车所给出的刹车警示，同时由于光线不是直接照射，也不会造成对眼部的刺激，能够有效的避免危险。
本发明的实施例对导光板5的形状和材质没有特别的限制，只要能够实现导光性能的材质都可以，例如，可为塑胶材质，如有机玻璃(PMMA)、PC板等，也可为玻璃等有导光性能的材质。导光板5的形状可采用能够增强车体美感的任何形状，如流线型。本发明的实施例对导光板5与固定件2之间的连接方式也没有特别限定，如可采用螺钉连接、卡扣连接、粘贴连接、超声波熔合等方式进行固定。
在本发明的实施例中，固定件2可为装饰条(以下称装饰条2)，装饰条的结构属于现有技术，与车体1的连接方式也可采用本领域常用的连接方式，在此不再累赘。在装饰条2的内部可形成有安装灯体1的卡槽。为加强与装饰条2的连接，灯体1可通过粘接剂安装在卡槽上，但装饰条2与灯体1之间的结合方式并局限于这一种安装结构，可以为任何能够彼此结合的安装方式。由于灯体1安装在装饰条2的内部，从外观上看，只会看见装饰条，从而不会影响车体的美观。
在本发明的实施例中，灯体1可由若干个发光LED(Light Emitting Diode，发光二极管)等间距的并联形成。发光LED的数目和间距可根据车型来确定，从经济角度考虑，一般安装间距为2.5mm～4mm比较合适。每个发光LED可由控制器4独立控制，控制器4与每个发光LED可通过空中对接的方式进行连接，即从控制器4引出的导线与从发光LED引出的导线在车体的某个部位进行连接。
在安装本发明的实施例的多向发光的行驶状态指示装置时，先将灯体1以照射方向朝向地面的方式固定在固定件2的内部，即发光LED的灯珠面对地面，然后将导光板5安装在灯体1的下方并固定在固定件2上。再将控制器4固定在车体3的内部，然后将灯体1通过空中对接的方式与控制器4进行连接，最后将固定件2与车体3固定连接在一起。
在实际应用中，本发明的实施例的多向发光的行驶状态指示装置能够实现多种功能，以动平衡车为例，如当动平衡车处于刹车模式时，控制器4会控制灯体1呈现第一发光状态，以起到刹车警示的作用；当动平衡车处于转向模式 时，控制器4控制灯体1呈现第二发光状态，以起到转向提示的作用；当动平衡车处于正常行驶模式时，控制器4控制灯体1呈现第三发光状态，以起到正常行驶提示的作用。以下对本实用型的多向发光的行驶状态指示装置的功能进行介绍。
1.刹车警示
当动平衡车处于刹车模式时，控制器4会控制灯体1呈现第一发光状态。具体地，当控制器4接收到动平衡车的减速信号时，会控制灯体1，使灯体1全部闪烁亮起，第一发光状态可为所有发光LED全部亮起的状态。此时，位于灯体1下方的导光板5会将灯体1发出的点光源通过折射和反射而直接转换为面光源，整个导光板5会变成一个面光源。同时，由于灯体的照射方向是朝向地面，所以地面也会形成一团光斑。此时，地面上的光斑和导光板5所传导的光一体形成一团光晕，如此，即使在强光的环境下，跟随在动平衡车后方的驾驶员或行人都能很清晰的看到动平衡车所给出的刹车警示，同时跟随在动平衡车后方的驾驶员或行人看到的是一团光晕，而不是光的直接照射，也不会造成对眼部的刺激，能够有效的避免危险。
控制器4可将动平衡车的减速强度分为几个不同的刹车等级，例如高、中、低三个刹车等级，刹车等级越高表示刹车强度越高。再根据不同刹车等级的刹车强度让灯体1闪烁亮起的亮度也不同。刹车强度越高，灯体1闪烁亮起的亮度也就越高。也可以同时控制灯体1的闪烁频率，例如，刹车等级为高的刹车情况下，可使得所有发光LED以较快频率进行闪烁，刹车等级为低的刹车情况下，可使得所有发光LED以较低频率进行闪烁。具体的闪烁亮度和频率可根据实际情况来确定，本发明的实施例对此不做特别的限定。这样，跟随的车辆和行人就可以根据灯体1的闪烁亮度和/或频率来判定前方行驶的动平衡车的刹车强度，从而做出相应的措施，避免不必要的危险。
2.转向提示
当动平衡车处于转向模式时，控制器4控制灯体1呈现第二发光状态，以起到转向提示的作用。具体地，当控制器4接收到动平衡车的转向信息后，会控制灯体1，让处于动平衡车转向相应方向的发光LED闪烁亮起，此时，第二发光状态为与第一发光状态不同的发光状态，即为位于与转向方向相一致方向的发光LED闪烁亮起的发光状态。例如，当动平衡车向左转向时，位于动平衡车左侧的发光LED会闪烁亮起。发光LED闪烁的顺序可不同，可按照沿转向方向由内向外的顺序依次闪烁亮起。
这样，跟随的车辆和行人根据刹车灯闪烁亮起的方向可看出动平衡车接下来的转动方向，做出相应的措施。而当动平衡车转向完成后，控制器4会接收 到相应的信息，让之前闪烁亮起的发光LED熄灭。
3.正常行驶提示
当动平衡车处于正常行驶模式时，控制器4控制灯体1呈现第三发光状态。具体地，当动平衡车在道路上正常行驶时，控制器4会控制灯体1的所有发光LED以一定的频率和一定的时间间隔进行闪烁，这种闪烁方式可称为“呼吸闪”。闪烁频率、闪烁时间间隔可根据实际需要来设定。如果动平衡车在夜间行驶时，控制器4会控制灯体1，让其亮起一定亮度的灯光，这样跟随在动平衡车后方的车辆或行人在很远的距离就可看到此灯光，就会知道前方有行驶车辆。这样，灯体1就起到了尾灯的作用。
综上，本发明的实施例的多向发光的行驶状态指示装置能够在车辆处于不同状态时，通过控制灯体的发光状态来起到指示作用，如刹车提醒、转向提醒和尾灯提醒等，即只需要安装一个灯体结构，就能够同时兼做刹车灯、转向灯和尾灯。
需要说明的是，灯体1的光源并不局限于单一颜色，其可为多色可变换，例如，转向时可为红色，刹车时可为黄色，尾灯时可为蓝色等。此外，尽管本发明的实施例介绍了动平衡车安装了本发明的实施例的指示装置，然而并不限于此，也可以在其他智能车辆上，例如智能自行车上安装本发明的实施例的指示装置。
上述说明示出并描述了本发明的若干优选实施例，但如前所述，应当理解本发明并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述发明构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围，则都应在本发明所附权利要求的保护范围内。
