Abstract
(EN) An anti-collision buffer device (1), comprising a housing (10) and a first energy-absorbing assembly (20). The housing (10) comprises a pair of first housing walls (11) and a pair of second housing walls (12), wherein the first housing walls (11) and the second housing walls (12) are alternately connected to form an accommodating space (100), the rigidity of the second housing walls (12) is less than the rigidity of the first housing walls (11), and the first energy-absorbing assembly (20) is accommodated in the accommodating space (100).
(FR) Dispositif tampon anti-collision (1), comprenant un logement (10) et un premier ensemble d'absorption d'énergie (20). Le logement (10) comprend une paire de premières parois de logement (11) et une paire de secondes parois de logement (12), les premières parois de logement (11) et les secondes parois de logement (12) étant reliées en alternance pour former un espace de réception (100), la rigidité des secondes parois de logement (12) étant inférieure à la rigidité des premières parois de logement (11), et le premier ensemble d'absorption d'énergie (20) étant logé dans l'espace de réception (100).
(ZH) 一种防撞缓冲装置(1),包括外壳(10)和第一吸能组件(20),外壳(10)包括一对第一壳壁(11)和一对第二壳壁(12),第一壳壁(11)与第二壳壁(12)交替连接形成容纳空间(100),第二壳壁(12)的刚度小于第一壳壁(11)的刚度,第一吸能组件(20)容设于容纳空间(100)内。
