Description

Vacuum Actuator for Air Conditioning System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system for controlling air ventilation and indoor pressure and cooling / heating inside an automobile, and more particularly, to a vacuum actuator for an air conditioning system for controlling each state of such an air conditioning system. will be.

In general, since the air inside the car is contaminated by the breathing of the occupant, it is necessary to draw fresh air (outside air) outside the car window and replace it with the air in the car interior. The vehicle is equipped with an air conditioning system composed of a blow unit for controlling the cooling, and a cooling and heater unit for controlling cooling and heating of the vehicle interior.

This air conditioning system controls the airflow and cold conditions in the air flow mode operating mechanism formed on the instrument panel of the driver's seat, and the air flow mode operating mechanism also functions to set the direction of the air coming from the air conditioner duct.

Such an air flow mode operating mechanism includes, for example, a direction indicator that indicates a direction in which wind flows toward a shape where a person sits, and is mounted in an air conditioning system by operation of the air flow mode operating mechanism. As described above, the actuator opens and closes an HVAC unit door composed of a blow unit, a cooling unit, and a heater unit, so that operation according to each mode is performed.

By the way, in the conventional air conditioning system of the automobile, the actuator for controlling the HVAC unit has a mechanical and a cable type, and in the case of a cable type actuator mainly used for small vehicles, the driver pulls the cable and operates it. There was a problem that the operation feeling was lowered and the opening / closing mode of the HVAC unit door was not obvious.

Accordingly, the present invention has been made to solve such a conventional problem, the object of the present invention is to improve the manner of the actuator for the air conditioning system, the structure is simple, the operator's operation is good, and the opening and closing mode of the HVAC unit door is made clear. It is done.

In order to achieve the above object, the present invention, the opening and closing of the HVAC unit door composed of a blower unit for adjusting the air ventilation and indoor pressure and cooling and heating of the vehicle interior, and the cooling unit and the heater unit on the instrument panel of the driver's seat An actuator for controlling according to the provided air flow mode operating mechanism, comprising: a diaphragm in which a vacuum degree and a vacuum state are controlled by the air flow mode operating mechanism to operate an internal power servo unit, and a diaphragm between the power servo mode and the diaphragm of the actuator It provides a vacuum actuator for the air conditioning system comprising a hose for transmitting a vacuum generated in the, and an operation unit for controlling the opening and closing of the HVAC unit door in the rear of the servo servo unit.

EXAMPLE

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

First, Figure 1 is a perspective view showing the structure of the vacuum actuator 1 according to the present invention, as shown, the vacuum actuator 1 according to the present invention is to operate the power servo unit 2 therein It is connected to the diaphragm 3. In addition, a hose 4 for transmitting a vacuum state generated in the diaphragm 3 is connected between the power servo unit 2 and the diaphragm 3 of the actuator 1, and behind the power servo unit 2. An operating part 5 for controlling opening and closing of the HVAC unit door is provided.

With this structure, the air-conditioning system equipped with the vacuum actuator 1 controls the on / off and degree of vacuum of the diaphragm 3 as the driver operates the air flow mode operating mechanism, thereby opening and closing the HVAC unit door. Will activate the mode.

As described above, according to the vacuum actuator for the air conditioning system according to the present invention, in place of the conventional cable-type actuator, the vacuum degree and the vacuum state according to the operation of the driver's air flow mode operation mechanism is turned on / off By providing the actuator of the air conditioning system, the structure of the air conditioning system is simple and the operation feeling is good, and the price is lower than the cable system.

Claims (1)

A diaphragm in which the degree of vacuum and the vacuum state are controlled by an air flow mode operating mechanism to operate the internal power servo unit, a hose transferring the vacuum generated in the diaphragm between the power servo unit and the diaphragm of the actuator, and the power servo unit A vacuum actuator for an air conditioning system, comprising an operation portion for controlling opening and closing of the HVAC unit door at the rear.
