The invention discloses a steering column height and angle adjusting mechanism which comprises a frame, a motor, a speed reducer, a lead screw, a nut, a lifting support and a column base fixedly connected with a steering column, the motor is connected with the upper end of the lead screw through the speed reducer, and the lower end of the lead screw is connected with the bottom of the frame through a bearing. The lead screw is connected with a nut capable of moving in the length direction of the lead screw. Two arc-shaped guide holes which extend from bottom to top and are bent towards the front side are formed in a side plate of the frame, and the left side and the right side of the tubular column base are movably connected with the arc-shaped guide holes through first sliding blocks. The lifting support is fixedly connected with the nut, horizontal guide holes extending in the front-back direction are formed in the left side and the right side of the lifting support respectively, and the left side and the right side of the tubular column base are movably connected with the horizontal guide holes through second sliding blocks. The angle and height of the steering column can be adjusted at the same time, excessive manual intervention is not needed, and the problems of high cost, large weight, difficult adjustment and the like caused by the complex structure of an existing steering column are effectively solved.

    本发明公开了一种转向管柱高度及角度调整机构,其包括框架、电机、减速器、丝杆、螺母、举升支架以及与转向管柱固定连接的管柱底座,电机通过减速器与丝杆的上端连接,丝杆的下端通过轴承与框架的底部连接,丝杆连接有可沿丝杆长度方向移动的螺母;框架的侧板上设有两条自下而上延伸且朝前侧弯曲的弧形导向孔,管柱底座的左右两侧通过第一滑块与弧形导向孔活动连接;举升支架与螺母固定连接,举升支架的左右两侧分别设有沿前后方向延伸的水平导向孔,管柱底座的左右两侧通过第二滑块与水平导向孔活动连接。本发明能够实现转向管柱角度及高度的同时调整,无需人工过多干预,有效地解决现有转向管柱结构复杂导致的高成本、大重量、难调整等问题。
