The present invention relates to an assembly structure of an actuator installed in an intake portion using a rotary intake door in an automotive air conditioner, and particularly to prevent high frequency noise by improving the sealing property of a rotary intake door. It relates to an actuator assembly structure for a rotary intake door that can be easily oversealed.

In general, a vehicle air conditioner is air conditioning the room by selectively sucking the air or bet to maintain the ventilation or temperature. Therefore, the intake portion of the air conditioner is provided with both an outside air inlet and an inside air inlet, and is adjusted to selectively suck the inside or outside air by using a door.

At this time, the door for adjusting the internal and external air is used a flat type (rotary type) or rotary (Rotary) door, the case of the flat type door is to be made by sealing by installing a sealing portion at the edge. On the other hand, in recent years, rotary intake doors have been used to prevent the occurrence of air leakage between the door case and the door.

In other words, it is important not to leak the wind through the cowl when driving the car in the betting mode. The rotary intake door has better sealing performance than the conventional flat type door and also has a great effect of preventing air leakage. However, there is a problem in that a high frequency noise passing between the air intake doors occurs when there is at least a small gap due to the characteristics of the rotary intake door.

Since the high frequency noise is a phenomenon caused by air leaks into a minute portion between the rotary intake door and the intake case, it can be solved by preventing the air leak between the rotary intake door and the intake case. Therefore, the intake portion of the air conditioner employing the rotary intake door prevents air leakage by applying over sealing to the rotary intake door. At this time, it is the actuator for driving the door that the over-sealing is applied to the rotary intake door.

Looking at the intake portion of the air conditioner employing the rotary intake door in detail, as shown in FIG. 1, the rotary intake is composed of the door body 11 and the sealing portion 12 to selectively open and close the inlet and the outside air inlet The actuator 20 to which the intake case 15 to which the door 10 is rotatably coupled and the drive shaft 13 of the rotary intake door 10 is coupled to drive the rotary intake door 10. Consists of

At this time, in order to drive the rotary intake door 10 while giving an over-sealing to the rotary intake door 10 installed inside the intake case 15, as shown in FIG. The actuators 20 are installed by using (32) and (33). Since the actuator 20 is coupled to the drive shaft 13 of the rotary intake door 10, when the actuator 20 is fixed in a slightly rotated state, the over seal is applied to the rotary intake door 10. I can support it in one state.

However, the conventional actuator assembly structure is simply a screw assembly of the actuator to the three fastening parts, it is difficult to set the exact position of the actuator when assembling the rotary intake door with the over-sealing state, the assembly position is shifted There is a problem that can occur.

That is, the actuator is coupled by fixing the position of the actuator in a state where the screw is fastened to any one of the three fastening parts and fastening the screw to the other fastening part. Since the assembly position can be shifted during the operation, the oversealing size will be changed for each operation.

In addition, since the actuator is assembled in a state in which the over-sealing is applied to the rotary intake door, the actuator may be rotated by the reaction force during the assembly of the actuator, thereby causing the assembly position to be displaced.

The present invention has been made in order to solve the above-described conventional problems, by applying an over-sealing to the door in a state in which any one of the three fastening parts are rotatable, fixing the other two fastening parts and finally fixing the first fastening part. It is an object of the present invention to provide an actuator assembly structure for a rotary intake door that prevents the actuator from being rotated by the reaction force during assembly of the actuator and prevents misalignment of the assembly position.

According to the actuator assembly structure for a rotary intake door of the present invention for achieving the above object, the intake case is composed of a door body and a sealing portion rotatably coupled to the rotary intake door for selectively opening and closing the inside and outside air inlet And an actuator installed on the outside of the intake case so as to be coupled to the drive shaft of the intake door housed inside the intake case, a boss formed on the intake case side, and a bracket formed on the actuator side to correspond thereto. In the actuator assembly structure for a rotary intake door comprising a fastening portion of; A guide pin is formed on one side of the boss and the bracket to protrude toward the other, and a guide hole on which the guide pin is rotatably inserted, so that any one of the fastening portions acts as a rotational support portion; The sealing part of the rotary intake door is characterized in that it is assembled in a pressurized state on the intake case side.

In addition, according to the actuator assembly structure for a rotary intake door of the present invention, at least one of the fastening portions other than the rotation support portion of the fastening portion is the actuator in the state in which the sealing portion of the rotary intake door is pressed toward the intake case side. To act as a support for fixing the support, it is characterized in that any one of the boss and the bracket is provided with a support member for limiting the movement of the other side.

In addition, according to the actuator assembly structure for the rotary intake door of the present invention, the support member is a locking structure, the locking projection provided on either side of the boss and the bracket and the locking groove into which the locking projection is inserted is installed on the other side Characterized in that consisting of a locking portion.

In addition, according to the actuator assembly structure for a rotary intake door of the present invention, the support member is characterized in that the guide rib is provided on any one side of the boss and the bracket is inserted into the other side.

Hereinafter, the actuator coupling structure for a rotary door of the present invention will be described with reference to the accompanying drawings.
