技术领域
本申请涉及车辆的标志领域，并且更具体地涉及具有发光标志的气囊罩盖和安全气囊装置。
背景技术
车辆具有用来指示车辆的品牌的标志。一些标志构造为发光标志，从而更加引人注目。发光标志安装在方向盘的气囊罩盖上。当车辆发生碰撞时，位于气囊罩盖内部的气囊充气膨胀，从而顶开发光标志展开，使得保护驾驶员。
发光标志通常具有标牌、底盖和光源。标牌的顶表面具有透光部，标牌和底盖之间界定封闭的空腔。光源发出的光传输至空腔内，并且通过透光部传输至外界环境中，从而形成特定的车标图案。底盖具有底壁和从底壁的周缘延伸的侧壁，以形成容纳槽并且将标牌包封在内，从而防止光泄露。
然而，现有技术中的发光标志零部件较多，导致尺寸较大、重量较重并且成本较高。因此，期望提供一种零部件较少的具有发光标志的气囊 罩盖。
发明内容
本申请的目的在于提供一种零部件较少的气囊罩盖和安全气囊装置。
本申请的一方面提供了一种气囊罩盖，其包括壳体和发光标志。壳体具有凹槽，凹槽的底表面形成有环形凹部。发光标志具有光源和标牌。标牌具有：顶盖，其上设置有透光部，和侧壁，其从顶盖的周缘延伸至环形凹部内，顶盖、侧壁与底表面之间界定封闭的空腔，光源发出的光能够传输至空腔内并且通过透光部传输至外界环境。
根据本申请的实施例，环形凹部设置在底表面的边缘处。
根据本申请的实施例，侧壁由不透光材料或者涂覆有不透光涂层的透光材料制成。
根据本申请的实施例，壳体具有底壁部和从底壁部的周缘延伸的周壁部，底壁部和周壁部界定凹槽。
根据本申请的实施例，多个安装部从顶盖延伸出并且沿周向间隔排列，底壁部设置有与多个安装部相对应的多个通孔，多个安装部插入通过相应的通孔并且从相应的通孔中伸出，多个安装部的伸出端焊接至壳体。
根据本申请的实施例，气囊罩盖还包括导光板，其位于空腔内，光源发出的光依次经由导光板和透光部传输至外界环境。
本申请的另一方面提供了一种安全气囊装置，其包括：如上所述的实施例的气囊罩盖；气囊，其容纳在气囊罩盖内；和气体发生器，其与气囊相连接，以用于对气囊进行充气。
根据本申请的气囊罩盖，标牌的侧壁延伸至凹槽的底表面上的环形凹部，侧壁与环形凹部相配合，就能起到挡光的作用，而不再需要现有技术中的底盖。因此，相比于现有技术，本实施例的气囊罩盖的零部件的数量减少，使得气囊罩盖的尺寸减小、重量减轻并且成本降低。

具体实施方式
以下将结合附图描述根据本申请的发光标志和气囊罩盖的具体实施例。下面的详细描述和附图用于示例性地说明本申请的原理，本申请不限于所描述的优选实施例，本申请的保护范围由权利要求书限定。
此外，空间相关术语(诸如“上”、“下”、“左”和“右”等) 用于描述附图所示的元件与另一个元件的相对位置关系。因此，空间相关术语可以应用到使用时与附图所示的方向不同的方向中。显然，虽然为了易于说明，所有这些空间相关术语指的是附图所示的方向，但是本领域技术人员能够理解可以使用与附图中所示的方向不同的方向。在本文中，上、下、左、右方向是驾驶员观察气囊罩盖时的上、下、左、右方向。
安全气囊装置包括气囊罩盖、容纳在气囊罩盖内的气囊和气体发生器。气体发生器与气囊相连接，以用于对气囊进行充气。
图1示出了根据本申请的实施例的气囊罩盖的局部剖视图，并且图2示出了根据本申请的实施例的移除了标牌的气囊罩盖的俯视立体图。如图1和图2所示，气囊罩盖1包括壳体10和发光标志20。壳体10具有主体部11和立壁12，主体部11呈拱形。当气囊罩盖1安装在方向盘上的状态下，主体部11面向驾驶员。立壁12突设在主体部11的背离驾驶员的表面上，并且气囊(未示出)容纳在主体部11和立壁12所包围的空间内。主体部11上设置有凹槽13，凹槽13大致位于主体部11的在左右方向上的中间位置处。凹槽13的底表面形成有环形凹部130，环形凹部130可以位于底表面的边缘处。
发光标志20包括光源21和标牌22，标牌22具有顶盖220和侧壁221。顶盖220上设置有透光部222，透光部222根据车标的图案进行设置。侧壁221从顶盖220的周缘延伸至环形凹部130内，使得顶盖220、侧壁221和底表面之间界定封闭的空腔。光源21发出的光能够传输至空腔内并且通过透光部222传输至外界环境，从而形成特定的车标图案。
在本实施例中，标牌22的侧壁221延伸至凹槽13的底表面上的环形凹部130，侧壁221与环形凹部130相配合，就能起到挡光的作用，而不再需要现有技术中的底盖。因此，相比于现有技术，本实施例的气囊罩 盖的零部件的数量减少，使得气囊罩盖的尺寸减小、重量减轻并且成本降低。此外，在气囊展开期间，由于需要顶开的气囊罩盖的部分的重量减轻，因此，气囊更能顺利地展开。
在本实施例中，凹槽13的深度设计为具有特定的深度，以防止由于深度太深而影响壳体10的强度，并且防止由于深度太浅而影响挡光效果。
图3是示出了根据本申请的另一实施例的气囊罩盖的局部剖视图。如图3所示，凹槽13的底表面上设置有附加壁114，标牌22的侧壁221位于凹槽13的侧表面与附加壁114之间。标牌22的侧壁221和附加壁114形成了双壁结构，以进一步防止光泄漏，并且在凹槽13的深度较浅的情况下，也能够可靠地防止光泄漏。在一个实施例中，附加壁114的伸出端抵靠标牌22的顶盖220。
替代地或者附加地，标牌22的侧壁221的外表面设置有毛毡(未示出)，例如黑色毛毡，以密封侧壁221的外表面与凹槽13的侧表面之间的间隙，从而防止光泄漏。
壳体10具有底壁部110和从底壁部110的周缘延伸的周壁部111，底壁部110和周壁部111界定凹槽13。凹槽13的侧表面与底表面大致垂直，标牌22的侧壁221和顶盖220大致垂直，并且标牌22的侧壁221的外表面与凹槽13的侧表面大致相贴合。标牌22的侧壁221由不透光材料制成，或者由涂覆有不透光涂层的透光材料制成。环形凹部130构造为适应标牌22的外轮廓的形状。在实施例中，标牌22为椭圆形(如下图4所示)，则环形凹部130也为椭圆形。
在实施例中，透光部222呈镂空状。气囊罩盖1还包括透光面板23，透光面板23位于气囊罩盖1的空腔内。透光面板23与标牌22的顶盖 220相接合，例如透光面板23与顶盖220相粘接。在与镂空状的透光部222相对应的位置处，透光面板23设置有突出部230，以伸入镂空状的透光部222内。如图1所示，突出部230的上表面与透光部222的上表面相齐平。
图4是示出了根据本申请的实施例的标牌的仰视立体图。如图4所示，标牌22上设置有多个安装部223，以用于安装至气囊罩盖1的壳体10。多个安装部223从顶盖220延伸并且沿周向间隔排列，其中，安装部223的一部分延伸超过侧壁221。在实施例中，安装部223位于侧壁221的内侧，并且安装部223的未延伸超过侧壁221的一部分与侧壁221的内侧相贴合。图5是示出了根据本申请的实施例的移除了标牌的气囊罩盖的局部俯视立体图。如图5所示，壳体10的底壁部110设置有与多个安装部223相对应的多个通孔112。
图6是示出了根据本申请的实施例的气囊罩盖的仰视立体图，其中，安装部的伸出端并未焊接；并且图7是示出了根据本申请的实施例的气囊罩盖的仰视立体图，其中，安装部的伸出端焊接至壳体。如图6和图7所示，安装部223插入通过相应的通孔112并且从相应的通孔112中伸出，安装部223的伸出端焊接至壳体10。安装部223的外表面的形状与通孔112的形状相适应，安装部223可以呈柱状。
返回参照图5，气囊罩盖1还包括导光板30，导光板30位于空腔内，光源21发出的光依次经由导光板30和透光部222传输至外界环境。光源21(例如LED)安装在导光板30的一端。沿着驾驶员的视线观察，导光板30大致占满凹槽13内的剩余空间，从而最大程度地使光源21发出的光填充整个空腔。在实施例中，光源21的数量为两个。导光板30的一端、特别是在椭圆形标牌22的长边方向上的一端设置有两个开口。光源 21分别位于相应的开口内。凹槽13的底表面上形成有多个凸起113，多个凸起113布设在导光板30的周边，从而使导光板30的位置固定。
参照图5至图7，气囊罩盖1还包括控制单元40，以用于对光源21进行控制。具体地，控制单元40用来控制光源21的颜色、亮度和点亮的形式(例如，单色静止、单色呼吸、变色呼吸和律动)。例如，控制单元40构造为PCBA板。控制单元40位于壳体10的主体部11的边缘处，并且通过柔性电路板50连接至光源21。
如前所述，尽管说明中已经参考附图对本申请的示例性实施例进行了说明，但是本申请不限于上述具体实施方式，本申请的保护范围应当由权利要求书及其等同含义来限定。
