The invention discloses a shock-proof headstock for an electric power-assisted bicycle. The shock-proof headstock comprises a lower plug and a bearing bowl, the bearing bowl is fixedly pressed in a lower pipe opening of the bicycle head pipe, and the lower plug is fixedly sleeved on the front fork; an outer chamfer formed by the lower plug is matched with an inner chamfer formed by the inner ring of the bearing bowl in a supporting manner, an assembly groove is further formed in the top surface of the lower plug, a PU gasket is positioned and clamped in the assembly groove, and a wear-resistant sheet is arranged on the annular top surface of the PU gasket in an anti-rotation manner; a pressure-bearing edge facing outwards in the radial direction is formed at the lower end of the bearing bowl outer ring, the bottom face of the pressure-bearing edge exerts pressure on the top face of the wear-resisting piece, and the wear-resisting piece is matched with the bottom face of the pressure-bearing edge in a friction rotation mode to generate a damping effect when the front fork rotates. The anti-vibration device is simple in structure and easy to assemble, and can effectively prevent the vibration of the electric power-assisted bicycle from being transmitted to a handlebar through a front fork to cause potential safety hazards to riding.

    本发明公开了一种电助力自行车用的避震车头碗,包括有下塞和轴承碗;轴承碗固定压装在车头管的下管口中,下塞固定套装在前叉上;下塞成型的外倒角与轴承碗内圈成型的内倒角支撑相配合,下塞的顶面上还成型有装配凹槽,装配凹槽中定位卡装有PU垫圈,PU垫圈的环形顶面上防转动的垫设有耐磨片;轴承碗外圈的下端成型有径向向外的承压边沿,承压边沿的底面施压在耐磨片的顶面上,该耐磨片在前叉转动时与承压边沿的底面摩擦转动相配合产生阻尼效果。本发明结构简易,装配简单,能有效阻止电助力自行车的震动经前叉传递到车把上,给骑行造成的安全隐患。
