The invention discloses an automobile mechanical anti-collision structure, and belongs to the technical field of anti-collision. Comprising a main beam (1), a locking piece, a sleeve (2) and a perforated ring (3), the sleeve (2) is arranged outside the main beam (1), the perforated ring (3) is rotationally arranged outside the sleeve (2), and the perforated ring (3) is fixed by the locking piece; a slotted plate (4) is fixed in the perforated ring (3), strip-shaped holes with sliding rods (5) are formed in the slotted plate (4) at intervals, a sliding frame (6) is arranged at the inner end of each sliding rod (5), one end of each sliding frame (6) is arranged on the sleeve (2) in a penetrating mode, the other end of each sliding frame (6) is connected with a fixing plate (7), and an anti-collision buffering cylinder (8) is arranged on the inner side of each fixing plate (7). The perforated ring (3) is rotated to drive the slotting plate (4), then the sliding rod (5) drives the sliding frame (6) to slide, the fixing plate (7) clamps the buffer cylinder (8), and the locking piece locks the perforated ring (3), so that the buffer cylinder (8) is fixed. The problems that an existing bumper and an existing energy absorption part are tedious in replacement operation and low in efficiency are solved.

    本发明公开了一种汽车机械防碰撞结构,属于防撞技术领域。包括主梁(1)、锁紧件、套筒(2)和开孔环(3),套筒(2)设置在主梁(1)外,开孔环(3)转动设在套筒(2)外,锁紧件固定开孔环(3);开孔环(3)内固有开槽板(4),开槽板(4)间隔设有带滑杆(5)的条形孔,滑杆(5)内端设有滑动架(6),滑动架(6)一端穿设在套筒(2)上,另一端连有固定板(7),固定板(7)内侧设有防撞缓冲筒(8)。转动开孔环(3)带动开槽板(4)再通过滑杆(5)带动滑动架(6)滑动,固定板(7)将缓冲筒(8)夹持,锁紧件锁紧开孔环(3)即固定缓冲筒(8)。解决现有保险杠和吸能零件的更换操作繁琐,效率低的问题。
