According to the steering wheel folding contraction hiding mechanism and the folding method, the steering wheel folding contraction hiding mechanism comprises a steering wheel assembly which can be folded, and the steering wheel assembly and a central shaft of the tubular column body assembly are fastened together; a tubular column body assembly which is provided with a cylindrical sliding rod anda rotating hole structure, the cylindrical sliding rod is matched with a rail on the sliding rail to control the motion trail of the tubular column body assembly, and the lead screw nut is installedin the rotating hole and can rotate around the axis of the rotating hole; a sliding rail, two groups of parallel rails are arranged on the sliding rail, and the sliding rail is fixed on a tubular column mounting mechanism in the instrument desk; a driving mechanism which is composed of a driving motor, a lead screw and a lead screw nut, and the driving motor is fixed to the sliding rail and drivesthe lead screw to rotate; the lead screw and the lead screw nut are provided with screwed threads, and rotating motion of the driving motor is converted into linear motion of the lead screw nut. Under automatic driving or parking scenes, the steering wheel can be folded and stored in an instrument desk. The cab space utilization rate is optimized, and the cab space is neater and more attractive.

    本发明的一种方向盘折叠收缩隐藏机构和折叠方法,包括:方向盘总成,自身可折叠。方向盘总成与管柱本体总成中心轴紧固在一起。管柱本体总成,管柱本体总成上有圆柱滑竿和旋转孔结构,圆柱滑竿与滑轨上的轨道配合控制管柱本体总成的运动轨迹,丝杆螺母安装在旋转孔内且可绕其轴线作旋转运动;滑轨,滑轨上设有两组平行的轨道,其自身固定于仪表台内部的管柱安装机构上;驱动机构,由驱动电机、丝杆和丝杆螺母构成,驱动电机固定在滑轨上,驱动丝杆旋转;丝杆和丝杆螺母有旋合的螺纹,将驱动电机旋转运动转变成丝杆螺母的直线运动。本发明在自动驾驶或停车场景下,可将方向盘折叠收纳进仪表台内。优化驾驶室空间利用率,驾驶室空间更加整洁美观。
