Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile equipment operating device, and is particularly suitable for a peak-P switching mechanism of an automobile air conditioner.

Conventionally, for example, in an automobile air conditioner having a defroster outlet, an upper outlet, and a lower outlet, mode switching is performed by controlling an electric circuit changeover switch at the point where a damper operates. , the electric circuit selector switch is in the airtral position or 1.
Since there are only three locations, the position of the diaphragm actuator can only be controlled at three locations. In this case, the states of the defroster outlet and the upper outlet, which are opened and closed by the damper, are as shown in the table below.
There are only '5 types, such as -1.

Therefore, in the HIA'l'' mode, a considerable amount of air flows through the lower outlet, so the air volume at the defroster outlet is insufficient.
As a result, it is difficult to remove fog from the window glass.

In the ℃ and D mode, the lower air outlet is closed, so although the #') of the window glass can be removed, there is a drawback that the feet get cold, and the above two drawbacks are particularly noticeable in cold regions.

The present invention was made in view of the above-mentioned drawbacks, and is a one-stroke type that electrically controls a diaphragm actuator that drives equipment such as a damper, and a valve that switches and introduces negative pressure or atmospheric pressure EE to the diaphragm actuator. An air circuit switch, a manual electric switch that is installed in a location that can be easily operated by the occupants in the single room, and that is switched on and off by manual operation;
The device is equipped with a movable contact that is displaced according to the movement of the device, and an electric circuit changeover switch that is a fixed contact that is in switching contact with the movable contact to form a neutral position of 211 points or more, and the fixed contact is connected to the manual electric switch. of the diaphragm actuator, and connects the diaphragm actuator to the diaphragm actuator, and energizes the electric pneumatic circuit breaker in accordance with the operating position of the manual electric switch, thereby determining the operating position of the device. The control position is now 4 cylinders,
It is an object of the present invention to provide an equipment operating device for an automobile that allows equipment such as a damper to be operated in more steps than before.
