The invention discloses a damping structure for an oil pipe clamp of a fuel tank. The damping structure comprises a pipe clamp body and pipe clamp sheets, and is characterized in that the outer wall of each pipe clamp sheet is evenly connected with a plurality of springs along the circumferential direction, the inner wall of the pipe clamp body is evenly provided with a plurality of guide holes along the circumferential direction, ends of springs are located in the corresponding guide holes, a plurality of stress relief holes are uniformly formed in the pipe clamp body along the circumferential direction of the pipe clamp sheets, and the stress relief holes and the guide holes are spaced apart and arranged symmetrically with respect to the circle centers of the pipe clamp sheets. On the basis of ensuring the damping performance of the pipe clamp body, the damping structure greatly reduces the stress concentration at the connection between the pipe clamp body and the springs, and avoidsfatigue damage of the pipe clamp body.
本发明公开了一种燃油箱油管管夹减震结构,包括管夹本体和管夹片,其特征在于:所述管夹片的外壁沿周向均匀连接有多个弹簧,所述管夹本体的内壁沿周向均匀设有多个导向孔,所述弹簧的一端位于导向孔中,所述管夹本体上沿管夹片的周向均匀设有多个应力释放孔,所述应力释放孔与所述导向孔间隔排布且关于管夹片的圆心对称。该减震结构在保证管夹本体的减震性能基础上,大大减小了管夹体与弹簧连接处的应力集中,避免了管夹本体发生疲劳损伤。
