The invention discloses a control structure of a steering return pin in an automobile steering switch. A long groove is formed in the center of a shell, a sliding groove is formed in the side wall ofthe long groove, a positioning column is arranged on the rear wall of the long groove, protruding blocks are arranged on the two sides of a push block, hooks are arranged above the protruding blocks,a counter bore is formed in the rear end face of the push block, a positioning column is arranged in the counter bore, and an arc-shaped pressing surface is formed on the front end surface of the pushblock. The push block is located in the long groove of the shell and clamps the sliding groove through the protruding blocks and the hooks, the two ends of the spring are nested in the two positioning columns, the return pin is a stepped plate, the protruding block is arranged in the middle of the top face, gaps are formed between the two sides of the protruding block and the top face of the stepped plate, and the return pin is located in the long groove of the shell; the sliding grooves in the two side walls of the long groove are embedded into gaps between the two sides of the protruding block and the top face of the stepped plate, the front end of the return pin extends out of the opening in the front end face of the shell, and the arc-shaped pressing surface of the front end face of the push block abuts against the end face of the protruding block. The structure solves the collision abnormal sound problem of the return pin, ensures the state balance of the return pin and the automatic return of the steering switch, and improves the application reliability of the steering switch.

    本发明公开了一种汽车转向开关中转向回位销的控制结构,本结构中壳体居中设有长槽,长槽侧壁设有滑槽、后壁设有定位柱,推块两侧设有凸块,凸块上方设有挂钩,推块后端面设有沉孔,沉孔居中设有定位柱,推块前端面设有弧形压面,推块位于壳体长槽内并且通过凸块和挂钩夹持滑槽,弹簧两端嵌套于两个定位柱,回位销为阶梯板并且在顶面居中设有凸块,凸块两侧与阶梯板顶面之间形成间隙,回位销位于壳体长槽内,长槽两侧壁的滑槽嵌入凸块两侧与阶梯板顶面之间的间隙内,回位销前端伸出壳体前端面的开口,推块前端面的弧形压面抵压凸块端面。本结构解决回位销的碰撞异响问题,确保回位销状态平衡以及转向开关自动回位,提高转向开关应用可靠性。
