The embodiment of the invention provides a damping structure suitable for a pin for a steering wheel and an automobile steering wheel, the damping structure is installed and fixed on a supporting piece of any one of the steering wheel or a safety air bag module and used for attenuating vibration transmission between the pin and surrounding parts, and a sleeve is fixed at a through hole in the supporting piece. The elastic piece is fixed on the supporting piece and provided with a supporting leg which always moves from the position outside the axial projection area of the through hole to the position inside the axial projection area of the through hole under the elastic bias action of the supporting leg, the tail end of the pin is provided with a clamping groove, the supporting leg is elastically embedded into the clamping groove, and the pin is provided with a step part. A damping piece is arranged between the step part and the upper end face of the sleeve and abuts against the step part and the upper end face of the sleeve in an interference mode. The elastic piece and the damping piece are arranged, the supporting leg of the elastic piece is embedded into the clamping groove in the tail end of the pin, the damping piece abuts against the position, close to the upper end face of the sleeve, of the pin in an interference mode, the pin is fixed, and the stability of the pin after installation is guaranteed.
本说明书实施例提供一种适于方向盘用销钉的阻尼结构及汽车方向盘,阻尼结构安装固定到该方向盘或该安全气囊模块的任意一方的支撑件上,用于衰减销钉与周围零件振动传递,套筒固定在支撑件上的贯通孔处,弹性件固定在支撑件上,具有受自身弹性偏压作用始终由贯通孔轴向投影区域以外的位置向贯通孔轴向投影区域以内位置移动的支腿,销钉末端具有卡止槽,支腿弹性地嵌入卡止槽,销钉上设有台阶部,台阶部与套筒上端面之间设有阻尼件,阻尼件分别于台阶部和套筒上端面过盈抵接。通过设置弹性件和阻尼件,弹性件的支腿嵌入销钉末端的卡止槽内,阻尼件与销钉靠近套筒上端面处的位置过盈抵接,实现对销钉的固定,保证销钉安装后的稳定性。
