The invention discloses an electric adjusting and positioning type steering wheel tubular column structure which comprises an outer cylinder, a telescopic motor, an inner cylinder and a telescopic positioning piece, the telescopic positioning piece of a rectangular structure and an inner cylinder rectangular guide groove used for being matched with and assembling the steering wheel are arranged, an abutting piece of an arc-shaped structure is replaced, torque fluctuation is counteracted by means of mutual abutting of the side edges of rectangular groove bodies, the vibration space of mutual rotation between the inner cylinder and the outer cylinder is reduced, large elastic force needed by an arc-shaped structure abutting piece is avoided, and the problems that due to the fact that multiple sets of gaskets and elastic piece structures are overlapped, the occupied length is large, and the space is large are solved.

    本发明公开了一种电动调节定位式方向盘管柱结构,包括外筒、伸缩电机、内筒和伸缩定位件,通过设置矩形结构的伸缩定位件,用以适配装配方向盘的内筒矩形导槽,代替了弧形结构的抵接件,依靠矩形槽体侧边相互抵接抵消扭矩波动,减少了内筒外筒之间相互转动的震动空间,避免了弧形结构抵接件所需的较大弹力,减少多组垫片及弹性件结构叠加造成的占用长度及空间较大的问题。
