The invention discloses a short-wheelbase steering structure for an automobile combination switch. In the structure, a PCB is arranged on a lower shell; a steering sliding block and a dimming slidingblock are arranged on the lower shell and are in sliding contact with a PCB contact along a steering rail and a dimming rail to realize steering and dimming functions; two ends of a steering return tension spring are fixed on the top surface of an upper shell; a Y-shaped shifting block is arranged in inner cavities of the upper and lower shells and is positioned through pin shafts and pin holes; the front end of a combination switch handle extends into an inner cavity of the Y-shaped shifting block; a steering shifting block is arranged on the bottom surface of the branch section of the Y-shaped shifting block and is movably connected with the steering sliding block; a steering return shifting block is hinged to the top face of the Y-shaped shifting block and located in a top face notch and connected with the middle of the steering return tension spring; the dimming shifting block is arranged in an inner cavity of the Y-shaped shifting block; the bottom end of the dimming shifting block is movably connected with the dimming sliding block; and the two ends of a dimming lifting pin abut against the position between the dimming shifting block and the front wall of the inner cavity ofthe Y-shaped shifting block. The steering structure saves the installation space, improves the convenience and reliability of the installation operation of the combination switch, and guarantees the use effect of the combination switch.

    本发明公开了一种用于汽车组合开关的短轴距转向结构,本结构中PCB板设于下壳体,转向滑块和变光滑块设于下壳体并且沿转向轨道和变光轨道滑移接触PCB板触点实现转向和变光功能,转向回位拉簧两端固定于上壳体顶面,Y形拨块设于上下壳体内腔并且通过销轴和销孔定位,组合开关手柄前端伸入Y形拨块内腔,转向拨块设于Y形拨块的分支段底面并且活动连接转向滑块,转向回位拨块铰接于Y形拨块顶面并且位于顶面槽口内,转向回位拨块连接转向回位拉簧中部,变光拨块设于Y形拨块内腔,变光拨块底端活动连接变光滑块,变光顶销两端抵靠于变光拨块与Y形拨块内腔前壁之间。本转向结构节省安装空间,提高组合开关安装操作的简便和可靠性,确保组合开关的使用效果。
