Specifically, when the locking linkage 41 rotates to drive the opening assembly 30 to switch to the matching state, the first detection surface 416 is opposite to the micro switch, the contact head 831 can contact with the first detection surface 416, and at this time, the micro switch is triggered to continuously send information to the control center, so that the safety release of the vehicle door can be judged; when the locking linkage 41 drives the opening assembly 30 to switch to the disengaged state, the second detection surface 417 is opposite to the micro switch, and the contact head 831 is opposite to the second detection surface 417 but not in contact (of course, the utility model can also be used for not limiting the contact), at this time, the micro switch is not triggered, the micro switch does not send information to the control center, and the door safety can be judged. By the arrangement, the detection precision of the micro switch can be improved, and the reliability of the central control mechanism 1 is improved.

In some alternative embodiments of the present utility model, the first detecting surface 416 and the second detecting surface 417 are connected by a connecting inclined surface 418, and an angle between the connecting inclined surface 418 and a horizontal plane is set as a, so that: a is more than or equal to 40 degrees and less than or equal to 60 degrees.

For example, referring to fig. 4, the first detecting surface 416 and the second detecting surface 417 may be connected by the connecting inclined surface 418, so that the contact 831 may be stably switched between the first detecting surface 416 and the second detecting surface 417, which may reduce the impact of the contact 831 during the movement process, and improve the service life of the micro switch.

Further, the angle between the connecting bevel 418 and the horizontal plane may be set to a, satisfying: a is more than or equal to 40 degrees and less than or equal to 60 degrees. That is, the angle a between the connection slope 418 and the horizontal plane may be taken as 45 °; alternatively, the angle a between the connecting bevel 418 and the horizontal may be taken to be 50 °; alternatively still, the angle a between the connecting bevel 418 and the horizontal plane may be taken to be 55 °, as the utility model is not limited in this regard. Thus, not only the movement smoothness of the contact 831 can be ensured, but also the height difference between the first detection surface 416 and the second detection surface 417 can be prevented from being too small, the possibility of erroneous judgment is reduced, and the reliability of the central control mechanism 1 is improved.
