下面， 结合附图对本发明的实施例进行详细地描述。
图 1示出了用于车辆的安全气囊模块。 如图 1所示， 车辆的顶棚内安 装有安全气囊模块 1。 安全气囊模块 1包括气体发生器、 气囊和壳体 11。 气体发生器置于气囊内， 并且气体发生器和气囊一起安装在壳体 11 中。 当车辆正常行驶时， 气囊通常呈叠合或卷起的状态容纳在壳体 11 内。 当 车辆发生碰撞时， 气体发生器被触发， 以对气囊充气。 气囊膨胀并展开， 在乘员与车辆的前方结构 （例如前挡风玻璃） 之间为乘员提供防撞击保 护。 在气囊碰撞展开时， 会对壳体产生冲击， 因此壳体向下凸起变形。 为 简洁起见， 在图中， 仅示出了壳体 11， 而省略了安全气囊模块 1的其他零 部件。 本领域的技术人员应当理解， 安全气囊模块 1包括本领域公知的其 他零部件。
在申请中， 术语“上” 、 “下” 、 “左” 、 “右”是由车辆上的乘员 观察时的方向。
车辆的顶棚上还安装有遮阳板 2。 遮阳板 2与安全气囊模块 1相对应 地设置在顶棚的内外两侧。 在本申请中， 顶棚的外侧是指顶棚的暴露于车 辆的车厢内的一侧， 而顶棚的内侧与外侧相反。
图 1还示出了根据本发明的实施例的遮阳板安装在车辆上的示意图。 如图 1所示， 安全气囊模块 1的壳体 11为遮阳板 2提供了安装界面。 为了 简洁起见， 仅示出了有利于对遮阳板 2 的结构进行描述的部件 （例如壳 体） ， 而省略了车辆的其他零部件。 本领域的技术人员应当理解， 车辆包 括本领域公知的其他零部件。
在本申请中， 以位于副驾驶座上方的遮阳板为例进行描述。 然而， 应 当理解， 根据本发明的遮阳板也可以适用于驾驶员上方的遮阳板。
图 2示出了根据本发明的一个实施例的遮阳板的构造的示意图。 遮阳 板 2包括遮阳板主体 21、 转动臂 22和支承臂 23。 遮阳板主体 21呈板形形 状。 转动臂 22的一端安装在顶棚上， 并且另一端可旋转地安装在遮阳板 主体 21上。 在一个实施例中， 转动臂 22包括形成为 L形的竖直部和水平 部。 竖直部大致沿竖直方向延伸， 并且水平部大致沿车辆的宽度方向延 伸。 竖直部可旋转地安装至车辆的顶棚面的右前角部。
通过使遮阳板主体 21围绕横向部的纵向轴线旋转， 遮阳板主体 21可 以在收纳位置与使用位置之间改变。 在收纳位置处， 遮阳板主体 21 的侧 面沿顶棚面布置， 并且在使用位置， 遮阳板主体 21可以遮挡阳光。
支承臂 23安装在遮阳板主体 21上， 并且由顶棚上的钩状件保持。 当 遮阳板主体 21围绕横向部的纵向轴线旋转时， 支承臂 23可以围绕其自身 轴线相对于钩状件旋转。 遮阳板主体 21在其长度方向上的两端被转动臂 22和支承臂 23支承。
根据本发明的实施例， 遮阳板主体 21设置有变形容纳空间 210, 变形 容纳空间 210位于转动臂 22与支承臂 23之间。 当壳体 11发生凸起变形 时， 变形容纳空间 210能够容纳壳体 11的变形。 与现有的遮阳板 2相比， 根据本发明的实施例的遮阳板 2在转动臂 22与支承臂 23之间设置变形容 纳空间 210， 以便于为壳体 11的向下 （即朝向遮阳板的方向） 凸起变形预 留一定的空间， 从而防止遮阳板 2在壳体 11 的撞击作用下从顶棚上脱落 并对乘客造成伤害。 此外， 如果在气囊展开时遮阳板 2处于使用位置， 壳 体 11的变形会对遮阳板 2产生冲击， 使得遮阳板 2能够回复到收纳位置或 正前方位置。 故， 根据本发明的实施例的遮阳板还可以避免乘客在扑向气 囊途中， 因碰撞到遮阳板而受到伤害。
在一个实施例中， 变形容纳空间 210形成为一开口。 该开口位于遮阳 板主体 21的上侧缘 211处并且沿遮阳板主体 21的厚度方向贯穿遮阳板主 体 21。 在一个实施例中， 开口呈矩形形状。 然而， 应当理解， 开口的形状 并不限于此并且可以是除矩形之外的其他形状， 例如， 梯形、 多边形或不 规则形状。
图 3示出了根据本发明的另一实施例的遮阳板 2的立体图， 其示出了 壳体 11 发生凸起变形之前的状态。 图 4示出了根据本发明的另一实施例 的遮阳板 2的立体图， 其示出了壳体 11发生凸起变形之后的状态。 图 5示 出了根据本发明的另一实施例的安装在壳体 11上的遮阳板 2的立体图， 其示出了壳体 11发生凸起变形之后的状态。
如图 3至图 5所示， 并同时参照图 1 （其示出遮阳板 2的另一实施 例） ， 遮阳板 2还包括变形组件 24。 变形组件 24设置在转动臂 22与支承 臂 23之间并位于变形容纳空间 210内。 在壳体 11发生凸起变形之前， 变 形组件 24用以维持遮阳板 2的强度。 在壳体 11发生凸起变形时， 变形组 件 24在壳体 11的撞击作用下能够变形使得其自身的形状适应于壳体 11的 变形。 通过设置变形组件 24, 根据本发明的实施例的遮阳板 2既能够保持 一定的强度， 又能够防止在壳体 1的撞击作用下从顶棚上脱落。 图 6示出了根据本发明的实施例的变形组件 24的分解图。 图 7示出了 根据本发明的实施例的变形组件 24的立体图， 其示出了壳体 11凸起变形 之前的状态。 图 8示出了根据本发明的实施例的变形组件 24的立体图， 其示出了壳体 11凸起变形之后的状态。
如图 6和图 8所示， 变形组件 24包括同轴布置的至少两个连杆。 连杆 之间连接为在变形组件 24受到壳体 11的撞击作用下， 每两个相邻的连杆 之间能够相对于彼此成角度。 在一个实施例中， 变形组件 24包括两个连 杆， 即， 第一连杆 241和第二连杆 242。
然而， 应当理解， 本发明并不限于此。 例如， 变形组件 24也可以包 括一个连杆。 该连杆具有弹性， 并且在受到壳体 11 的撞击作用下发生伸 长并弯曲变形， 以适应壳体 11的变形。
根据本发明的实施例， 两个连杆的端部之间通过销轴 243连接， 每个 连杆的与另一个连杆相连接的端部分别设置有用于容纳销轴 243 的引导槽 2411、 2421。 引导槽 2411、 2421 分别沿相应的连杆的轴线延伸。 在变形 组件 24受到壳体 11 的撞击作用下， 销轴 243能够在每个引导槽 2411、 2421 内沿相应的连杆的轴线滑动。 由此， 两个连杆 241、 242作为一个整 体而言伸长并弯曲， 以适应壳体 11的变形。
然而， 应当理解， 本发明并不限于此。 只要在壳体 11 的撞击作用 下， 两个连杆 241、 242作为一个整体而言伸长并弯曲， 两个连杆 241、 242之间可以通过本领域公知的其他方式连接。
根据本发明的实施例， 遮阳板主体 21包括转动臂安装部 212和支承 臂安装部 213。 在一个实施例中， 转动臂 22可旋转地安装在转动臂安装部 212上， 并且支承臂 23固定地安装在支承臂安装部 213上。 第一连杆 241 的未设置有引导槽 2411 的端部例如通过螺纹连接或通过包塑方式固定地 安装在转动臂安装部 212上。 第二连杆 242的未设置有引导槽 2421的端部 例如通过螺纹连接或通过包塑方式固定地安装在支承臂安装部 213上。
在替代实施例中， 第一连杆 241 与转动臂 22—体地形成， 并且第二 连杆 242与支承臂 23一体地形成。 在该实施例中， 转动臂 22可旋转地安 装在转动臂安装部 212上， 并且支承臂 23可旋转地安装在支承臂安装部 213上。 由此， 当遮阳板 2在收纳位置与使用位置之间转动时， 第一连杆 241与第二连杆 242之间不会发生相对转动。
根据本发明的实施例， 连杆 241、 242呈圆柱形。 然而， 应当理解， 连杆 241、 242也可以为长方体、 三棱柱、 不规则形状或其它形状。 根据 本发明的实施例， 每个连杆 241、 242的直径均相同。
图 1和图 5示出了根据本发明的安全气囊组件。 如图 1和图 5所示， 安全气囊组件包括安全气囊模块 1和遮阳板 2。 安全气囊模块 1包括壳体 11、 气囊和气体发生器。 气体发生器置于气囊内， 气囊安装在壳体内。 遮 阳板 2与安全气囊模块 1相对应地设置在车辆的顶棚的内外两侧。 当气囊 充气膨胀时， 壳体 11向遮阳板 2所在的方向凸起变形， 遮阳板 2的变形容 纳空间 210能够容纳壳体 11的变形。 安全气囊模块 1和遮阳板 2的具体构 造可以参照上文所述， 在此不再进行展开描述。
根据本发明的实施例的遮阳板可以用于各种类型的车辆中， 例如， 轿 车、 卡车、 公共汽车等。
尽管已经参考示例性实施例描述了本发明， 但是应理解， 本发明并不 限于上述实施例的构造。 相反， 本发明意在覆盖各种修改例和等同配置。 另外， 尽管在各种示例性结合体和构造中示出了所公开发明的各种元件， 但是包括更多、 更少的元件的其它组合也落在本发明的范围之内。
