本发明涉及一种具有低峰值吸能结构的高集成一体化汽车顶棚,包括：顶棚外板、低峰值吸能结构层、内饰板；低峰值吸能结构层是由多个单元胞体在X向上依次排列组合而成的立体结构；单元胞体由从上之下间隔均布设置的内凹四边形吸能部和用于连接相邻两个内凹四边形吸能部的连接板构成；内凹四边形吸能部包括水平方向对称设置的两个第一横向吸能部、竖直方向上与第一横向吸能部对称设置的两个第二横向吸能部、水平方向对称设置的两个第一竖向吸能部、竖直方向上与第一竖向吸能部对称设置的两个第二竖向吸能部。该顶棚碰撞初始峰值低,吸能过程稳定,吸能效果好,安全性和舒适性可同时保证。

The invention relates to a highly integrated integrated automobile roof with a low-peak energy-absorbing structure, including: an outer roof panel, a low-peak energy-absorbing structure layer, and an interior trim panel; the low-peak energy-absorbing structure layer is composed of multiple unit cells in X A three-dimensional structure that is arranged and combined upwards in sequence; the unit cell body is composed of concave quadrilateral energy absorbing parts evenly spaced from top to bottom and a connecting plate for connecting two adjacent concave quadrilateral energy absorbing parts; concave quadrilateral The energy absorbing part includes two first lateral energy absorbing parts symmetrically arranged in the horizontal direction, two second lateral energy absorbing parts arranged symmetrically to the first lateral energy absorbing part in the vertical direction, and two first lateral energy absorbing parts symmetrically arranged in the horizontal direction. The vertical energy absorbing part, and two second vertical energy absorbing parts arranged symmetrically with the first vertical energy absorbing part in the vertical direction. The ceiling has a low initial peak value, stable energy absorption process, good energy absorption effect, and safety and comfort can be guaranteed at the same time.
