By making it possible, the door structure of the vehicle air conditioner to improve the productivity by reducing the assembly work time and assembly labor.

In general, the vehicle air conditioner selectively passes the outside air introduced into the vehicle interior through an air inlet by a blower unit to an evaporator through which refrigerant flows or a heater core through which coolant of the vehicle engine flows. After the heat exchange by the heat exchanger, the air chamber is configured to cool or heat the vehicle interior by distributing in various directions of the vehicle interior in a cold or warm state through an air discharge port connected to each part of the vehicle interior.

As shown in FIGS. 1 and 2, the air conditioning apparatus includes a pair of first case members 100a and a second case member 100b divided left and right, and an air inlet 101 is provided at an inlet side. And an air-conditioning case 100 having a defrost vent 102, a front vent 103, and a floor vent 104 at an outlet side, and the air-conditioning case 100. The inside includes an evaporator 105 and a heater core 106 sequentially installed at predetermined intervals so as to heat exchange the air introduced from the air inlet 101 side by a blower unit (not shown). Temporary door (Temp Door, 107) between the evaporator 105 and the heater core 106 to adjust the temperature of the air discharged into the vehicle interior through the vent (102, 103, 104) according to the opening degree Is installed. In addition, each vent (102, 103, 104), by selectively controlling the amount of cold / warm air flowing in accordance with the opening degree of the temper door (107) for each blowing mode (front mode, defrost mode, floor mode, Blowing mode doors 108, 109, and 110 for discharging into the vehicle in the bi-level mode and the mixed mode) are respectively provided.

Each door shaft of the temporal door 107 and the air blowing mode doors 108, 109, and 110 is rotated in association with respective driving means installed at an outer side of the air conditioning case 100.

For example, the driving means for driving the blowing mode doors, although not shown in the drawings, is typically connected to the cable (Cable) that is stretched in accordance with the operation of the blowing mode switch installed in the instrument panel (Instrument Panel) in the vehicle interior or rotate A cam plate rotatably supported on an outer wall surface of the air conditioning case so as to be rotated by a separate actuator, and one end is connected to a slot formed in the cam plate, and thus the cam plate rotates. A lever rotatably supported on an outer wall surface of the air conditioning case to rotate, and a link arm connected to one end of the lever and installed at an end of the door shaft to rotate in accordance with the rotation of the lever.

As a result, when the cam plate rotates, the door shaft rotates as the link arm rotates through the lever, and the ventilation mode door rotates inside the air conditioner case 100 by the rotation of the door shaft. 103, 104) to adjust the opening degree.

However, the blower mode doors 108, 109, and 110 have a plate-type structure similar to the temporal doors 107, and are provided at the inlets of the vents 102, 103, and 104, respectively. Therefore, when opening and closing the vents 102, 103, and 104, a wide rotation radius is required, thereby limiting the miniaturization of the air conditioning case. In addition, due to the need to connect each door shaft to the drive means individually, there is a problem that the work efficiency is reduced by increasing the number of parts as well as the number of assembly work.                         

Accordingly, in recent years, by using only one rotatable door as a blower door mode door for selectively adjusting the opening degree of each vent, there is a trend of reducing the number of parts and the assembly labor for the air conditioner.

Conventionally, in order to assemble the blowing mode door 200 having such a structure to the air conditioning case 300, formed on the side wall of any one case member of the first and second case members 300a and 300b divided left and right. After assembling the blower mode door 200 while the end of one of the door shafts 201a is inserted into the shaft hole, the insertion position of the shaft hole formed in the side wall of the opposite case member and the end of the other door shaft 201a is inserted. While matching, it forms the said case member, and finally the operation | work which sets the drive means for driving the said blowing mode door to the said door shaft was performed.

However, when the ventilation mode door is mounted on the air conditioning case, the door shaft end of the ventilation mode door should be aligned with the side hole of each case member while the air conditioning case is divided left and right, and the door shaft and the air conditioning case In addition to the hassle of adjusting the insertion position in order to precisely adjust the insertion position of the side hole, it is necessary to assemble the divided case member after this operation, which causes a problem in that work efficiency is reduced such as a considerable time for assembly work. there was.

Furthermore, after the case members are divided as described above, the operation means for separately setting the driving means for driving the door shaft on the outer wall of the air conditioning case must be performed. There was a problem that the workmanship and productivity are lowered due to increased assembly labor.

Accordingly, the present invention has been made to solve the above problems, by allowing the blowing mode door to be easily assembled in a slide type from the outside of the air conditioning case, and to simplify the setting of the drive means, An object of the present invention is to provide a blower mode door assembly of an air conditioner for a vehicle that can improve productivity by reducing assembly time and assembly labor.

As shown in FIG. 9, an outer surface of the sealing member 40 has a through hole (not shown) that is connected to the door shaft 30a and is driven in a rotatable manner, and the door shaft 30a is rotatably driven. A lower case 50a having an internal space into which a driving means (not shown) can be built; The drive means box 50 is formed of the upper case 50b detachably coupled by the locking means 51 to the lower case 50a.

However, the drive means box 50, the lower case 50a of the drive means box 50 is injection molded integrally with the outer surface of the seal member 40 to be formed integrally with the seal member (40). It is a structure.

When the drive means box 50 is mounted on the sealing member 40 in the same manner as described above, it does not require a component such as a screw for mounting the drive means, as well as a separate assembly operation compared to the prior art. Since there is no need to do this, there is an advantage in that not only the cost can be reduced but also the assembly work can be greatly reduced.

When there is an abnormality in the driving means set in the drive means box 50, the upper case 50b may be opened to easily perform maintenance work.

Furthermore, when the sealing member 40 integrally equipped with the drive means box 50, the rotatable door 30, and the door cover 20 are modularized as one assembly, it can be handled as a single unit. Therefore, not only the parts management is convenient, but also the assembly labor can be greatly reduced as compared with assembling the sealing member and the driving means in the rotatable door as in the first embodiment, and the productivity can be improved.

Thus described with reference to Figure 10 the action of the rotary door 30 mounted to the air conditioning case 10 as follows.

As shown in FIG. 10 (a), when the driver or the passenger selects the front mode by operating a blowing mode switch installed on the instrument panel of the vehicle interior, the air introduced into the air conditioning case 10 is rotated. Passes through the openings and the ventilation holes formed in the body door 30 and the door cover 20, respectively. That is, the center and side openings 32a and 32b of the rotatable door 30 are positioned to communicate with the center vent 12 and the side vent 13 of the air conditioning case 10, and the defrost vent 11. The floor vent is closed by the outer circumferential wall 31 of the rotary door 30.

As a result, the air introduced through the opening 35 of the rotatable door 30 passes through the center and side openings 32a and 32b of the rotatable door 30 and the air vents of the door cover 20. Through 20a), it is discharged to the front of the vehicle interior through the center vent 12 and the side vent 13.

At this time, a part of the air introduced through the opening part 35 of the rotatable door 30 passes through the side opening 33 of the rotatable door 30 and passes through the air passage of the sealing member 40. It is always discharged to the side of the vehicle interior through the side vent 13 of the air conditioning case 10 along the (41).

In addition, in the case of being switched to the defrost mode by the operation of the air blowing mode switch, as shown in FIG. 10 (b), the opening part 35 of the rotating body door 30 is formed in the air-conditioning case 10. Located in communication with the frost vent 11, the center vent 12, the side vent 13 and the floor vent are closed by an outer circumferential wall 31 of the rotary door 30.

As a result, the air introduced through the center and side openings 32a and 32b of the rotatable door 30 passes through the opening 35 of the rotatable door 30 and the ventilation hole 20a of the door cover 20. ) Is discharged to the windshield of the vehicle interior through the defrost vent (11).

At this time, similar to the front mode, a part of the air introduced through the center and side openings 32a and 32b of the rotatable door 30 is passed through the side opening 33 of the rotatable door 30. It is always discharged to the side of the vehicle interior through the side vent 12 of the air conditioning case 10 along the air passage 41 of the sealing member 40

In the case of switching to a blower mode other than this, the rotating body door may be rotated as described above to adjust the position of the opening as appropriate.

As described above, according to the present invention, after the air blowing mode is slidably assembled from the outside of the air conditioning case to the inside through a hole formed in one side wall of the air conditioning case, it is configured in an assembly form so as to seal the hole. Since there is no need to assemble the left and right case members after adjusting the door shaft of the blower mode door and the insertion position of the shaft space formed on the inner wall of the air conditioning case, Not only can the assembly work be easily performed, but the assembly work time can be shortened, and the overall workability and productivity can be improved.

Further, according to the present invention, in the blower mode door assembly, a driving means box incorporating a drive means is integrally set in the seal member for sealing the hole of the air conditioning case, and the seal member is set in the blower mode door and the door. By modularizing together with the cover, not only can the assembly work be greatly reduced compared to the prior art, but also the productivity can be greatly improved by the cost reduction.

Although the present invention has been described with respect to the preferred embodiment, the present invention is not limited thereto, and various modifications and applications will be possible to those skilled in the art without departing from the gist of the present invention.
