The invention relates to the technical field of automobile collision avoidance, and provides a machining process of an energy absorption structure, an energy absorption device and an automobile, the energy absorption structure comprises three cavities which are arranged in parallel and sequentially connected in the first direction, and each cavity is of a rectangular shell structure with the hollow interior; the parts, exceeding the middle cavity, of the two cavities at the two ends are connecting parts; the machining process of the energy absorption structure comprises the steps that before the connecting plate is formed through the pressing process, chamfering operation is conducted on the outer right-angle portions of the four side edges of the connecting part, so that outer side chamfers are formed; and before the connecting plate is formed through the pressing process, inner chamfering operation is carried out on the four inner corner parts of the connecting part so as to form inner side chamfers. According to the energy absorption device, the size of protrusions on the surface of the connecting plate formed after the side edges of the cavity are pressed through the pressing process can be effectively reduced, the flatness of the energy absorption device after the pressing process is correspondingly improved, and therefore the matching effect of the energy absorption device and other parts of an automobile is improved.
本发明涉及汽车防撞技术领域,并提供一种吸能结构的加工工艺、吸能装置及汽车,吸能结构包括平行设置并沿第一方向依次连接的三个型腔,所述型腔为内部空心的矩形壳体结构;两端的两个所述型腔超出中间的一个所述型腔的部分为连接部分;所述吸能结构的加工工艺包括:在通过压合工艺形成连接板之前,对所述连接部分的四个侧棱的外直角部位进行倒斜角作业,以形成外侧倒角;在通过压合工艺形成连接板之前,对所述连接部分的四个内角部位进行内倒角作业,以形成内侧倒角。本发明可以有效减少后续通过压合工艺对型腔的侧棱进行压合之后形成的连接板的表面的凸起大小,相应提高吸能装置在压合工艺后的平面度,以提高与汽车的其他零配件的匹配效果。
