As shown in fig. 1 to 3, the fixed column 4 is fixedly disposed on the golf self-driving car C, the fixed column 4 has a hollow space 40, the hollow space 40 is used for accommodating the manual steering shaft 3, an inner diameter surface 401 of one side of the fixed column 4 has a column inner engaging portion 41, and the displacement driving mechanism 2 drives the movable sleeve 1 to move in an axial direction a1 of the movable sleeve 1, so that the sleeve outer engaging portion 12 is engaged with the column inner engaging portion 41.
As shown in fig. 1 to 3, one end of the automatic steering shaft body 5 is connected to an automatic steering mechanism E, and the outer diameter surface 501 of the automatic steering shaft body 5 has an automatic shaft body engagement portion 51, and the movable sleeve 1 is moved in the axial direction a1 of the movable sleeve 1 by the driving of the displacement drive mechanism 2, and the sleeve inner engagement portion 11 is engaged with the automatic shaft body engagement portion 51.
As shown in fig. 1 to 4, in the operation control device 100 of the golf self-driving steering wheel according to the embodiment of the present invention, the displacement of the moving sleeve 1 toward the manual steering shaft 3 and away from the automatic steering shaft 5 in the axial direction a1 of the moving sleeve 1 is performed by the driving of the displacement drive mechanism 2, so that the sleeve outer engagement portion 12 is engaged with the column inner engagement portion 41, and the sleeve inner engagement portion 11 is disengaged from the automatic shaft engagement portion 51, thereby performing the automatic driving of the golf self-driving vehicle C. In this state, the moving sleeve 1 is disengaged from the automatic steering mechanism E, and on the other hand, the moving sleeve 1 is engaged with the manual steering shaft body 3 and the fixed column body 4, so that the manual steering shaft body 3 cannot rotate in the hollow space 40 of the fixed column body 4, and the steering wheel S is locked.
