Description

Automotive air conditioning unit {AIR CONDITIONING APPARATUS FOR VEHICLE}

The present invention relates to a combination structure of a vehicle air conditioner case, and in particular, the combination structure relates to a vehicle air conditioner suitable for use as a heater unit storage case having a defroster outlet and a face direction outlet.

10 and 11 schematically show a conventional vehicle air conditioner case. The case 200 is used as a case for accommodating a heater unit downstream of the cooling unit among air conditioner units.

Among the upper surfaces of the case 200, a defroster outlet 5 is formed at the front side of the vehicle, and a face direction outlet 6 is formed adjacent to the vehicle rear side, and a partition portion 7 extending in the vehicle left and right directions between the outlets. ) Is formed.

In addition, inside the case 200, the defroster door 50 and the face direction door 60, which are mode switching doors, are disposed below the defroster outlet 5 and the facewise outlet 6, respectively.

On the other hand, the lower surface of the case 200 is provided with a leg direction outlet (not shown), and the leg direction door 80 which is a mode conversion door is disposed.

The defroster 50 and the face direction door 60 are attached so that the rotation shaft is fitted by a left side of the case 200 and a wall surface (not shown) formed inside the case 200 facing the left side. It is. For this reason, in order to combine the defroster door 50 and the face direction door 60 with the case 200, the case 200 is a defroster outlet 5, the face direction outlet 6, and the partition 7 It needs to be divided into a first dividing surface A which extends in the front and rear of the vehicle across the approximately central portion of the.

In addition, the heater core 2 is arranged at the vehicle right side portion of the case 200 which is an upstream side of the air flow than the defroster outlet 5 and the face direction outlet 6. In addition, the heater core 2 is inserted into the case 200 in a direction substantially perpendicular to the rotation shaft 50a of the defroster 50 and the rotation shaft 60a of the face direction door 60. It is attached so that it may be fitted by the wall surface used as the front side of the 200, and the wall surface used as the back side.

For this reason, in order to combine the heater core 2 with the case 200, the second divided surface that extends in the vehicle left and right directions and divides the portion containing the heater core 2 of the case 200 in the front and rear directions of the vehicle 200. The case 200 needs to be divided into (B). As a result, the case 200 needs to be divided into a first divided surface A and a second divided surface B, which is a surface substantially perpendicular to the first divided surface A, with the division starting point C as the center. It can only be divided into three.

In this manner, the three divided case dividers 1a, 1b and 1c are engaged by engaging the clip 100 with the fixing portions 101 formed in the respective case dividers 1a, 1b and 1c.

By the way, in the case of the air conditioner for vehicles of this kind, size reduction of the case is calculated | required. Here, it is necessary to narrow the width of the front and rear direction of the case partition portion in order to reduce the size of the front and rear direction of the vehicle without reducing the opening area of each blowout port to secure the air volume.

However, in the case of the coupling structure of the case divider as described above, since the two case dividers are combined into one clip 100, a plurality of clips 100 are required, and for attaching the clip 100 to each other. It needs space. In particular, in order to increase the adhesiveness between the case dividing portions in the vicinity of the dividing point C of the case dividing portions 1a, 1b and 1c, the clip 100 is placed on the partition portion 7 where the dividing base point C is located. ) Is attached. For this reason, it is necessary to secure the space for arranging the clip 100 in the partitioning portion 7, and the width of the partitioning portion 7 in the front-back direction of the vehicle is also widened, making it difficult to miniaturize the case.

Accordingly, the present invention has been made in order to solve the above-mentioned problems, and has a defroster ejection outlet and a face direction ejection outlet formed adjacent to each other, and divided into three parts as a split point in a vehicular air conditioner case which divides the ejection section. Therefore, an object of the present invention is to provide a case combination structure that can be miniaturized without having to reduce the opening area of each outlet.

In order to achieve the above object, according to the present invention, the case (1) crosses substantially the central portion of the first outlet (50), the second outlet (60) and the partition portion (7) partitioning the first and second outlets. The first dividing surface A, which extends so that the heater core 2 is not stored, is divided into a first case dividing portion 1a and a portion in which the heater core 2 is stored. The part in which the core 2 is accommodated is the second case by the second partition surface B which divides the part in which the heater core 2 is received through the partition 7 from the first partition surface A. It is divided into the division part 1b and the 3rd case division part 1c, and each case division part 1a, 1b, 1c overlaps with the other two case division part in the part which comprises the partition part 7, The overlapping portions 71a, 71b, 71c having overlapping portions 71a, 71b, 71c, which are arranged to overlap, are integrally coupled by the coupling means 73.

As a result, the overlapping portions 71a, 71b, 71c formed in the case dividing portions 1a, 1b, 1c are overlapped, so that the three case dividing portions 1a, 1b, 1c are integrated by one coupling means. The number of coupling means necessary for integrally coupling the three case dividers 1a, 1b, and 1c can be reduced. Therefore, the space of the partitioning part 7 which is necessary for arrange | positioning a coupling means can be made small, and a case can be miniaturized without having to make small the opening area of a 1st outlet and a 2nd outlet.

Moreover, in each case division part 1a, 1b, 1c, since the overlap part 71a, 71b, 71c joined by the coupling means is arrange | positioned so that it may overlap, three cases are fixed by fixing only in one direction. The divisions 1a, 1b, 1c can be integrally coupled, and the three case divisions 1a, 1b, 1c can be integrally coupled by a coupling means of a simple structure.

Moreover, the structure of the said overlap part can be carried out like invention of Claim 2. That is, in one of the case dividing portions 1c of the second case dividing portion 1c and the third case dividing portion 1c, the overlapping portion formed in the portion constituting the partition portion 7 is the bent portion 71c, In the partitioning part 7, the bent part 71c is overlapped so that it may be fitted by the overlap part 71a, 71b formed in the other case division part 1a, 1b.

As the coupling means of the overlapping portions 71a, 71b, 71c, the screw member 73 can be used as in claim 3. For this reason, since it can couple | bond without using a clip like conventionally, the space which arrange | positions a clip in the partition 7, and the fixing part for fixing a clip are unnecessary. In this way, the same effect as described in claim 1 can be obtained by the screw member 73 which is a simple coupling means.

According to the invention of claim 4, together with claim 3, the screw insertion hole 70 into which the screw member 73 is inserted reaches the overlapping portions 71a, 71b, 71c from the side surface of the first case dividing portion 1a. If so formed, the combination of the screw members 73 becomes simple, and the work efficiency is improved.

The vehicle front side (defroster ejection outlet 5 side) is the 2nd case division part 1b and the other side (face direction ejection outlet) among the thing divided into 2 in the 2nd division surface B as the division part 1a. 6) the side) as the third case divider 1c.

First, the structure of the said 1st-3rd case division part 1a, 1b, 1c is demonstrated with reference to FIGS. 3 is a cross-sectional view of the first case divider 1a, FIG. 4 the second case divider 1b, and FIG. 5 the third case divider 1c as viewed from the first split surface A side. 3 to 5, each mode change door is indicated by a dashed-dotted line.

As shown in FIGS. 3 and 4, the pivot shaft hole 10 and the door stopper 10a, into which the pivot shaft 50a of the defroster door 50 is pivotably fitted, are coupled to the first case divider 1a. ) And the inner surface of the second case dividing portion 1b are provided opposite to the vehicle left and right directions, and as shown in FIGS. 3 to 5, the rotation shaft 60a of the face direction door 60 can rotate. The pivot shaft hole 11 and the door stopper 11a, which are fitted together to be fitted together, are provided on the inner surfaces of the first case divider 1a and the third case divider 1c so as to face the vehicle left and right directions.

3 to 5, the rotation shaft hole 12 is formed by the first case dividing portion 1a and the second portion so that the rotation shaft 80a of the legwise door 80 is rotatably fitted. The inner surface of the case dividing portion 1b is provided to face the vehicle left and right directions, and the door stopper 12a is provided on each inner surface of the first to third case dividing portions 1a to 1c.

In addition, a partition plate 8 extending from the partition portion 7 to the inside of the case 1 is provided on each inner surface of the first and second case partitioning surfaces 1a and 1b, so that the air-conditioning air is defroster outlet 5. ) And a face-out outlet 6 are formed.

In addition, a support shaft 13 having a support seat for installing the heater core 2 and a pivot shaft hole 14 into which the pivot shaft of the air mixing door 3 is fitted are coupled to the second case partition 1b. It is provided in the inner surface of the 3rd case division part 1c facing the vehicle front-back direction.

Next, the structure of the partitioning part 7 of the case 1 which is a main part of this invention is demonstrated.

6 shows the case top shape in the vicinity of the partition portion 7. In addition, FIG. 6 shows a state in which three case dividing portions 1a, 1b, and 1c are separated, and the first and second dividing surfaces A and B each have a dashed line A and a ( It is shown by B). In addition, about the defroster door 50 and the face direction door 60, parts other than rotation shaft 50a, 60a (two dashed line) are abbreviate | omitted, and the whole about the leg direction door 80 is abbreviate | omitted. 7 is an enlarged view of part (D) of FIG. 6.

Here, among the first, second and third case dividing portions 1a, 1b, and 1c, the portions constituting the capsular portion 7 are respectively divided into a first partitioned partition portion 7a and a second divided partition portion 7b. It is called 3rd partitioning partition part 7c.

The third partitioning partition portion 7c is formed with a bent portion 71c that bends from the vehicle left and right directions to the vehicle front and rear directions. The curved portion 71c has a side surface 71a of the first partitioned partition portion 7a facing the first partition surface A and a side surface of the second partitioned partition portion 7b facing the first partition surface A. It overlaps so that it may be fitted by 71b. The side surfaces 71a and 71b and the bent portion 71c are each configured as an overlapping portion of the divided partition portions 7a, 7b, and 7c, respectively.

In addition, in the vehicle left-right direction, the second partitioned partition portion 7b is shorter than the third partitioned partition portion 7c by the plate thickness of the bent portion 71c. For this reason, when each partition partition part 7a-7c overlaps with each overlapping part 71a-71c, the other engagement part of each case division part 1a-1c is also in close contact.

Moreover, the screw insertion hole 70 is formed so that it may reach | attain the overlap part 71a-71c from the side of the vehicle left side of the 1st case division part 1a. The through hole 72 is provided in each of the first partitioned partition portion 7a and the bent portion 71c, and the attachment hole 72 is provided in the second partitioned partition portion 7b. It consists of a screw hole penetrating 71c). And each overlap part 71a-71c is fastened by the screw screw 73 as a screw member.

Here, the through hole 72 of the first partitioned partition portion 7a and the bent portion 71c is simply a through hole of the screw screw 73, whereby the through hole 72 of the first partitioned partition portion 7a. Is smaller than the diameter of the screw screw (73) seat.

Next, the combination method of the case 1 is demonstrated with reference to FIG. 7 based on the said structure.

First, the air mixing door 3 is attached to open the second dividing surface B so as to be fitted to the second case dividing portion 1b and the third case dividing portion 1c. At this time, the rotation shaft of the air mixing door 3 is rotatably fitted in the rotation shaft hole 14. Coupling portions other than the overlapping portions 71b and 71c of the case dividing portions 1b and 1c are coupled to the second dividing surface B by, for example, fastening members such as screws and clips.

Subsequently, each of the mode change doors 50, 60, and 80 opens the first divided surface A to the combined second and third case dividers 1b and 1c and the first case divider 1a. Attached to fit.

At this time, the rotation shaft 50a of the defroster door 50 is connected to the rotation shaft hole 10 of the first and second case dividing portions 1a and 1b, and the rotation shaft 60a of the face direction door 60 and The pivot shaft 80a of the legwise door 80 is rotatably fitted into the pivot shaft holes 11 and 12 of the first and third case dividers 1a to 1c. In the case dividing portions 1a and 1c, engagement portions other than the overlapping portions 71a to 71c are engaged in the first dividing surface A by fastening means such as screws or clips, for example. .

At the end of the steps up to this point, the bent portion of the third partitioned partition portion 7c is formed by the side surface 71a of the first partitioned partition portion 7a and the side surface 71b of the second partitioned partition portion 7b. 71c is overlapped so that a partition part 7 may be formed. Then, the screw screw 73 inserted into the screw insertion hole 70 is fitted into each of the through holes 72, and as shown in Fig. 8, the overlapping portions 71a to 71c are fastened to the case (1). The combination of is complete. 8 is a sectional view seen from above of a horizontal cut in the portion of the screw hole 72.

By the way, according to this embodiment, since the clip can be combined in the partition part 7 without using a clip, the space which arrange | positions a clip and the clip fixing part for fixing a clip to the partition part 7 becomes unnecessary. 10 and 11 show a case of this field in the related art, and the length of the case in the front and rear directions of the case is conventionally about 300 mm and in this embodiment about 260 mm. Here, the length of the partition portion in the front and rear direction of the vehicle is conventionally about 60 mm and the present embodiment is about 20 mm.

Thus, according to this embodiment, the length of the space which was conventionally provided for connecting each case division part 1a-1c with a clip is reduced. For this reason, size reduction of a case can be realized without having to make small the opening area of the defroster ejection opening 5 and the face direction ejection opening 6.

In addition, since a duct for air-conditioning air is attached to the defroster outlet 5 and the face-direction outlet 6, a packing material such as a sponge or rubber is attached to the partition portion 7.

For this reason, when connecting each case division part 1a-1c using a T-shaped clip etc. at the point C where each case division part 1a-1c overlaps, for example, conventionally, a clip In addition, although the level | step difference by the clip fixing part generate | occur | produces and the adhesiveness of a packing material worsens, in this embodiment, since the screw screw 73 does not come out to the upper part of the partition part 7, since a flat surface can be ensured, there is no problem.

In addition, according to this embodiment, since the screw screw 73 is inserted into the screw insertion hole 70, even if the engaging part other than the partition part 7 is attached first and the case 1 is integrated, the screw Since the screw 73 can be easily combined with the overlapping parts 71a-71c from the exterior of the case 1, work efficiency improves.

In addition, according to the present embodiment, since the partition portion 7 is to be joined with a screw screw 73 instead of fastening the three-part coupling portion in a conventional manner, the number of parts is reduced and the process is reduced. Simplification of the numbers can be achieved.

Moreover, according to this embodiment, since each case division part 1a-1c is arrange | positioned so that the overlap part 71a, 71c to which the screw screw 73 may be attached may overlap, each case is provided by the coupling means of a simple structure. The division parts 1a-1c can be combined.

Further, the bent portion may be formed in the second divided partition portion rather than the third divided partition portion. In this case, the bent portions of the second partitioned partition are overlapped to form sandwiches in the first and third partitioned partitions.

In addition, the overlapping structure in the bent portion 7 may be one in which not only the above embodiment but also the overlapping portions 71a to 71c are formed as shown in the sectional view of FIG. 9A or 9B. In such a case, the screw screw 73 is arrange | positioned in the vehicle front-back direction in the overlapping parts 71a-71c, and fastens each overlapping part 71a-71c. Also in the structure of the said overlap part, the effect similar to the said embodiment can be acquired. Of course, the overlapping structure in the partitioning part 7 is not limited to the said embodiment and FIG. 9A, 9B.

In addition, the positional relationship in the vehicle left-right direction of both the blower outlets of the defroster blower outlet 5 and the face-direction blower outlet 6 and the heater core 2 may be the opposite position to the said embodiment.

In addition, the coupling means of the overlapping portion in the partitioning portion may be provided so that the overlapping portion is fitted with irregularities.
