Abstract

汽车塑料后防撞梁,其特征在于包括塑料材料制成的横梁主体,在横梁主体的左右两侧制有倾斜向后的支杆,横梁主体与支杆的中部制有凹槽,在左右两侧的支杆上制有安装盒,安装盒的底部制有安装孔,安装盒中制有吸能盒,吸能盒顶部制有吸能槽。通过将整个横梁注塑采用塑料材料注塑成型,在横梁主体的两侧制有倾斜向后的支杆,横梁主体与支杆中部制有凹槽,支杆上制有安装盒,安装盒中制有吸能盒,当车辆在受到低速的撞击时,塑料材料制成的吸能盒通过溃缩有效吸收低速撞击时的能量,缓减碰撞力度,吸能效果优异,并能避免撞击力对车身的前后纵梁造成损害,从而减少低速碰撞后零部件更换的数量和更换成本。

Description

汽车塑料后防撞梁
技术领域
本实用新型涉及汽车塑料后防撞梁,属于汽车零部件领域。
背景技术
防撞梁是汽车上特殊的重要功能零件,是用来减轻车辆受到碰撞时吸收碰撞能量的一种装置。防撞梁由主梁、吸能盒、以及连接汽车的安装板组成,主梁、吸能盒都可以在车辆发生低速碰撞时有效吸收碰撞能量,尽可能减小撞击力对车身纵梁的损害。已有的防撞梁通常采用钢防撞梁,钢防撞梁整体重量重,制造麻烦,钢材成本高,即使车辆在受到低速碰撞时,钢防撞梁也会因碰撞变形而对车身的前后纵梁造成损害,低速碰撞后更换部件多,更换成本高。
发明内容
本实用新型的目的是为了克服已有技术存在的缺点,提供一种重量轻,制造方便,降低制造成本,车辆发生低速碰撞时有效吸收碰撞能量,吸能效果优异,避免撞击力对车身前后纵梁损害的汽车塑料后防撞梁。
本实用新型汽车塑料后防撞梁的技术方案是:其特征在于包括塑料材料制成的横梁主体,在横梁主体的左右两侧制有倾斜向后的支杆,横梁主体与支杆的中部制有凹槽,在左右两侧的支杆上制有安装盒,安装盒的底部制有安装孔,安装盒中制有吸能盒,吸能盒顶部制有吸能槽。
本实用新型公开了一种汽车塑料后防撞梁,通过将整个横梁注塑采用塑料材料注塑成型,在横梁主体的两侧制有倾斜向后的支杆,横梁主体与支杆中部制有凹槽,支杆上制有安装盒,安装盒中制有吸能盒,当车辆在受到低速的撞击时,塑料材料制成的吸能盒通过溃缩有效吸收低速撞击时的能量,缓减碰撞力度,吸能效果优异,并能避免撞击力对车身的前后纵梁造成损害,从而减少低速碰撞后零部件更换的数量和更换成本。
本实用新型汽车塑料后防撞梁,所述的横梁主体后侧制有后加强筋,凹槽中制有前加强筋。前、后加强筋能提高横梁主体和支杆的结构强度。所述的安装盒中制有安装盒加强片,吸能盒中制有吸能盒加强片。有了安装盒加强片和吸能盒加强片,能提高安装盒和吸能盒的结构强度。
附图说明

图2是本实用新型汽车塑料后防撞梁的背面立体示意图。
具体实施方式
本实用新型涉及一种汽车塑料后防撞梁,如图1—图2所示,其特征在于:包括塑料材料制成的横梁主体1,在横梁主体的左右两侧制有倾斜向后的支杆2,横梁主体与支杆的中部制有凹槽3,在左右两侧的支杆上制有安装盒4,安装盒的底部制有安装孔5,安装盒中制有吸能盒6,吸能盒顶部制有吸能槽7。通过将整个横梁注塑采用塑料材料注塑成型,在横梁主体1的两侧制有倾斜向后的支杆2,横梁主体与支杆中部制有凹槽3,支杆2上制有安装盒4,安装盒中制有吸能盒6,当车辆在受到低速的撞击时,塑料材料制成的吸能盒6通过溃缩有效吸收低速撞击时的能量,缓减碰撞力度,吸能效果优异,并能避免撞击力对车身的前后纵梁造成损害,从而减少低速碰撞后零部件更换的数量和更换成本。所述的横梁主体1后侧制有后加强筋8,凹槽3中制有前加强筋9。前、后加强筋9、8能提高横梁主体1和支杆2的结构强度。所述的安装盒4中制有安装盒加强片10,吸能盒6中制有吸能盒加强片11。有了安装盒加强片10和吸能盒加强片11,能提高安装盒4和吸能盒6的结构强度。
