The invention provides a detachable automobile front bumper which comprises a mounting frame fixed on an automobile chassis, a fixing bolt with a built-in circumferential limiting structure is embedded on the mounting frame, the front bumper is locked and fixed on the mounting frame through a self-locking bolt, and the detachable automobile front bumper is characterized in that the self-locking bolt is composed of a group of double-layer bolts which are coaxially arranged; the tail end is provided with a locking piece which is triggered by relative displacement of the double-layer bolt and is unfolded in the radial direction, circumferential self-locking of the self-locking bolt is conducted in cooperation with the fixing bolt structure, by means of the arrangement of the double-layer bolt, the outer side bolt is used for fixing the front bumper, and the inner side bolt drives the tail end limiting structure to be unfolded through relative displacement of the inner side bolt and the outer side bolt. The angle of the outer side bolt is limited, the limiting structure is automatically unfolded and stored after the outer side bolt is locked through torque transmission between the two bolts, additional operation is omitted, and good development prospects are achieved.
本发明提供了一种可拆式汽车前杠,包括固定在汽车底盘上的安装架,安装架上嵌设有内置周向限位结构的固定栓,前杠通过自锁螺栓锁止固定在安装架上,其特征在于,自锁螺栓由双层的同轴设置的一组螺栓组成,尾端设置有通过双层螺栓的相对位移触发的径向展开的锁止件,配合固定栓结构进行自锁螺栓的周向自锁,利用双层螺栓的设置,外侧螺栓用于对前杠的固定,而内侧的螺栓则通过与外侧螺栓的相对位移驱动尾端限位结构展开,实现对外侧螺栓的角度限位,且通过两螺栓之间的扭矩传递,限位结构的展开收纳在外侧螺栓的锁紧后自动进行,免去了额外的操作,具有良好的发展前景。
