At this time, the seat-side air passages on which the person boards are opened, and the doors 20, 22, and 24 of the air passages 12, 14, and 16 are closed to close the seat-side air passages on which the person does not board.

Here, the doors 22 of the passenger-side air passage 14 include deep doors 22a, face doors 22b and floor doors 22c, as shown in FIGS. 22a, 22b, and 22c are operatively connected to the front passenger door cam 30 installed on the outside of the air conditioning case 10, and the doors 22a, 22b, and 22c thus connected are the front passenger door cams. According to the " rotational position "

For example, Vent Mode, Def Mode, Floor Mode, Bi-Level Mode, Mix Mode, Close Mode Controlled.

For reference, the "vent mode" is a mode for discharging the cold and hot air of the air conditioning case 10 in the passenger's face direction, and the "diff mode" is a mode for discharging the cold and hot air in the window glass direction, and the "floor mode". Is a mode for discharging cold and hot air to the floor surface of the vehicle interior.

"Bi-level mode" is a mode for discharging cold and hot air to the floor of the passenger compartment and the face of the passenger, and "Mix mode" is a mode for discharging cold and hot air to the window pane and the floor of the passenger compartment. "Close mode" is a mode for blocking both cold and hot air.

Typically, the doors 22a, 22b, 22c of the passenger seat air passage 14 are controlled in a "closed mode" by the passenger door cam 30 when it is detected that no person is in the passenger seat, and so controlled. The doors 22a, 22b and 22c of the passenger seat air flow passage 14 are closed to completely block the cold and hot air supplied to the passenger seat side by closing each flow path (not shown) to the passenger seat side. Therefore, the cooling and heating of the passenger seat is limited.

On the other hand, the passenger seat door cam 30, as shown in Figure 4, is provided with a plurality of slots 32, each of these slots 32, the rotary shaft 22a of each door (22a, 22b, 22c) The connecting pin 26a of the arm 26 provided at -1, 22b-1, 22c-1 is slidably assembled.

When the actuator 30a is operated according to a specific control signal, the front passenger door cam 30 may organically adjust the opening angles of the doors 22a, 22b, and 22c while moving forward and backward by the actuator 30a. To control. Therefore, each door 22a, 22b, 22c is controlled to a "specific mode."

Next, the features of the vehicle air conditioner according to the present invention will be described in detail with reference to FIGS.

First, referring to FIGS. 3 and 4, the air conditioner of the present invention includes an interlocking means 40 for interlocking the rear seat door 24 of the rear seat air passage 16 and the passenger seat door cam 30. .

The interlocking means 40 is the rotating shaft 22c-1 of the specific door 22c, for example, the floor door 22c, among the plurality of doors 22a, 22b, 22c connected to the passenger seat door cam 30. The rear door cam 42 is installed at, and the arm 44 is installed on the rear door 24 to be connected to the rear door cam 42.

The rear seat door cam 42 is provided integrally with the rotary shaft 22c-1 of the floor door 22c and rotates integrally with the floor door 22c.

The rear door cam 42 receives the rotational force of the passenger seat door cam 30 transmitted to the floor door 22c as it rotates integrally with the floor door 22c. In particular, the rotational force of the passenger seat door cam 30 which controlled the floor door 22c in the "specific mode" is received as it is.

Therefore, when the floor door 22c is controlled by the passenger seat door cam 30 in the "specific mode", the rear seat door cam 42 is also controlled in accordance with the "specific mode" position in association with this. For example, the floor door 22c is positioned by the passenger door cam 30 in the "vent mode", "bi level mode", "floor mode", "mix mode", "diff mode", and "close mode" positions. The rear door cam 42 is also controlled to the "vent mode", "bi level mode", "floor mode", "mix mode", "diff mode", and "close mode" positions while being controlled in this manner.

On the other hand, the rear door cam 42 is provided with the slot 42a. The slot 42a is formed to be bent along the circumferential direction while having a different distance from the center of rotation C of the rear seat door cam 42, and the rear door 24 is formed in the slot 42a thus formed. The arms 44 of are connected.

The arm 44 is integrally assembled to the rotation shaft 24a of the rear seat door 24, and is provided at the end thereof with a connecting pin 44a fitted to the slot 42a of the rear door door cam 42.

This arm 44 rotates while cam-rotating along the slot 42a of the rear door cam 42 at the time of rotation of the rear door cam 42. In particular, when the rear door cam 42 is rotated to the "specific mode" position while interlocking with the passenger seat door cam 30, the "specific position" in accordance with the bending shape of the slot 42a moved to the "specific mode" position. Rotate to

Thus, the rear seat door 24 connected to the arm 44 can also be rotated to a "specified position" while interlocking with the passenger seat door cam 30. Thereby, the opening position of the rear seat door 24 with respect to the rear seat air flow path 16 is adjusted.

As a result, the rear-seat door 24 of the rear-seat air passage 16 makes it possible to control the rear-seat air passage 16 while interlocking with the passenger seat doors 22a, 22b, and 22c. Accordingly, it is possible to control the cold and hot air supplied to the "rear seat" without a separate actuator for controlling the rear door 24.

On the other hand, the slot 42a of the rear door cam 42 controls the " rotation position " of the arm 44 according to its bending shape, wherein the arm (" rotation position " It has a structure to cam 44 to two positions (X, Y).

That is, the slot 42a of the rear seat door cam 42 is moved into the "bi level mode", "floor mode", and "mix mode" positions while the rear door cam 42 is interlocked with the passenger seat door cam 30. When rotated, as shown in Fig. 4, the arm 44 has a structure for cam motion to the first position (X).

And, when the rear door cam 42 is rotated to the "close mode", "diff mode" position while interlocking with the passenger seat door cam 30, as shown in Figure 5, the arm 44 is removed It has a structure to cam-move to 2 positions (Y).

At this time, the first position X of the arm 44 is a position where the rear seat door 24 connected to the arm 44 opens the rear seat air flow path 16, and the second position Y of the arm 44. Is the position where the rear seat door 24 connected with the arm 44 closes and closes the rear seat air flow path 16.

In conclusion, the slot 42a of the rear door door cam 42 is configured such that the front passenger door cam 30 moves the front passenger side doors 22a, 22b, and 22c into "by level mode", "floor mode", and "mix mode". When controlling, the rear seat air passage 16 is opened by interlocking the rear seat doors 24. Thus, cooling and heating of the rear seat portion can be controlled in conjunction with cooling and heating of the passenger seat side.

And the slot 42a of the rear door cam 42 has a rear door when the front passenger door cam 30 controls the front passenger side doors 22a, 22b, and 22c in "close mode" and "deep mode." It has a structure which closes and closes the rear seat air flow path 16 by interlocking 24). Therefore, whether the cooling or heating of the rear seat portion can be controlled according to the cooling, heating "mode state" on the passenger seat side.

Here, when controlling the passenger seat side doors 22a, 22b, and 22c in the "close mode", the rear air passage 16 is also shut off to stop cooling and heating of the rear seat part. Controlling 22b, 22c) in "close mode" to stop cooling and heating on the passenger seat means that there are no passengers in the passenger seat, and in most cases, there are no passengers in the rear seat (A). Because.

Therefore, when controlling the passenger seat side doors 22a, 22b, and 22c in the "close mode", it means that there are no passengers in the rear seats, so that the rear air passage 16 is blocked to stop cooling and heating of the rear seats. Because you need to.

And when controlling the passenger seat side doors 22a, 22b and 22c in the "diff mode", the reason why the rear air passage 16 is cut off to stop cooling and heating of the rear seat part is that the passenger seat side doors 22a and 22b. , 22c) controlling the "deep mode" means that the front windshield will generate steam frost, and if the windshield occurs windshield, there is a risk of a safety accident. This is to quickly remove the mist of window glass by concentrating the air supplied to the part to the window glass.

On the other hand, the slot 42a of the rear seat door cam 42 interlocks the rear seat door 24 even when the passenger seat door cam 30 controls the passenger seat side doors 22a, 22b, and 22c in the "vent mode". And close the rear seat air passage 16.

However, in the state where the passenger seat side doors 22a, 22b, and 22c are controlled in the "vent mode", even when the rear seat door 24 closes the rear seat air passage 16, the internal structure of the air conditioning case 10 (rear seat air). The upper portion of the flow path 16 is in communication with the face vent (not shown)] is a structure in which cold, hot air is supplied to the rear air passage (16).

Therefore, in the state where the passenger seat side doors 22a, 22b, and 22c are controlled to the "vent mode", even if the rear seat door 24 closes the rear seat air passage 16, cold and hot air are supplied to the rear seat part A. It is cooled and heated.

According to the air conditioner of the present invention having such a configuration, since the rear door 24 for controlling cooling and heating of the rear seat portion is controlled by interlocking with the passenger seat door cam 30, the rear seat door without a separate actuator ( 24) can be controlled.

In addition, since the rear seat door 24 can be controlled without an actuator, the number of parts can be reduced, whereby an effect of cost reduction can be expected.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.

For example, in the detailed description and the drawings in the present invention, the rear door 24 is described as being controlled in conjunction with the passenger seat door cam 30. 50) (see Fig. 3) can be controlled in conjunction with. Thereby, the rear seat door 24 can also be driven by the actuator 50a of the driver's seat door cam 50. As shown in FIG.

In this case, the interlocking means 40 is configured to operatively connect the driver's seat door cam 50 and the rear seat door 24.

Preferably, the rear seat door 24 is interlocked with the passenger seat door cam 30 among the passenger seat door cam 30 and the driver's seat cam 50.

This is because the passenger boarding of the rear seat portion A is more related to the passenger seat portion than the driver's seat portion.

That is, if there is no passenger in the passenger seat portion, in most cases, it is likely that there is no passenger in the rear seat portion (A). Thus, the rear seat portion A has a relatively high relation with the passenger seat portion compared to the driver's seat portion.

Accordingly, by interlocking the rear seat door 24 with the passenger seat door cam 30, the rear seat portion A and the passenger seat portion interlock with each other to cool and heat, thereby enabling more efficient operation of cooling and heating in the cabin. It becomes possible. In particular, it is possible to operate the cooling and heating in the vehicle more efficiently without consuming energy and unnecessary parts.
