The invention discloses a hollow front auxiliary frame with a collision energy absorption structure, which comprises an auxiliary frame body welding assembly, an auxiliary anti-collision beam welding assembly and a rear cross beam, and is characterized in that the auxiliary frame body welding assembly is provided with an auxiliary frame body groove structure for guiding collision collapse; the auxiliary anti-collision beam welding assembly is connected with the auxiliary frame body welding assembly; the rear cross beam is connected with the auxiliary frame body welding assembly; compared with a welding auxiliary frame, the auxiliary anti-collision beam can be detached independently, and the maintenance cost of a user is reduced; compared with a cast aluminum auxiliary frame, a welding and assembling process can be used for producing a sample piece with a larger size specification; compared with a frame type auxiliary frame popular in the market, the auxiliary frame anti-collision beam is additionally arranged, a weak link two-layer collision safety function design is designed on the auxiliary frame body, on the premise that energy absorption crumple of direct collision and offset collision is met, the stress of a vehicle body is evenly shared, the collision safety of the whole vehicle is improved, and meanwhile the leg invasion amount can be reduced.

    本发明公开了一种带碰撞吸能结构的空心前副车架,包括:副车架本体焊接总成,副防撞梁焊接总成和后横梁,所述副车架本体焊接总成具有副车架本体凹槽结构,用于引导碰撞溃缩;所述副防撞梁焊接总成与所述副车架本体焊接总成连接;所述后横梁与所述副车架本体焊接总成连接;本发明与焊接副车架相比,副防撞梁可进行单独拆卸,降低用户维修成本;与铸铝副车架相比,焊接+装配的工艺可生产更大尺寸规格样件;与市面上流行的框架式副车架相比,增加副车架防撞梁、副车架本体上设计薄弱环节两层碰撞安全功能设计,在满足正碰、偏置碰吸能溃缩的前提下,均匀的分担车身受力,提高整车的碰撞安全性,同时可减少腿部侵入量。
