First, as shown in FIG. 7, the vehicle air conditioning unit 10 includes an intake unit 11 that selectively takes in vehicle interior air and vehicle exterior air, and a cooler unit 12 that cools the air flowing down from the intake unit 11. The air cooled by the cooler unit 12 is branched at a desired ratio, and a part of the air is heated by the heater core 13 to obtain air at a predetermined temperature or without being heated. The heater unit 17 is introduced into various ducts D such as Df, defrost duct Dd or rear duct Dr, and is blown out into the vehicle compartment from the vent port 14, the foot port 15, the defrost port 16 and the like, and is provided at a substantially central portion in the vehicle width direction Air volume, temperature, and blowout by a controller (not shown) installed in the installed Instroir 30 Etc. appropriately controls the vehicle interior occupant is performing air-conditioning of the vehicle interior to a desired temperature state.

In FIG. 7, reference numeral "18" is an evaporator, "19" is an inside air intake, "20" is an outside air intake,
“21” is a blower, and “M” is a motor.

Next, the cluster lid 31 is attached to the front surface of the instroer 30, and the inside opening 31a is
It is a frame in which the audio device 40 and the like are stored. There are various types of audio equipment 40, but in general, a tape deck, a radio, a CD player and the like.

The various instruments are speedometers, fuel gauges, etc. embedded in the instrument panel 1, and the steering member 41 is made of a steel rod and supports the operating rod of the steering wheel. The center console 42 is a box-shaped one having a rear duct Dr inserted therein and a small container or the like formed therein.

The procedure for assembling the parts mounted in front of the front seat of the passenger compartment is generally as follows.

1) Before laying a carpet in the vehicle compartment, one member Df1 of the floor duct Df in the vehicle air conditioning unit 10 is provided with a bracket or an angle (hereinafter collectively referred to as a bracket) provided upright from the floor panel 2. B
Attached) and the other member Df2
Also install in the same way.

2) Mount the heater unit 17 on the dash panel 3 or the like. As shown in FIG. 8, the heater unit 17 has a plurality of brackets 17B protruding from the unit case 17a, and is connected to the vehicle body side brackets 3B such as the dash panel 3 by bolts or the like. Connection here is a difficult task.

3) Attach the steering member 41 and the instrument panel supporting bracket 1B to the dash panel 3 and the like.

4) Attach the rear duct Dr to the floor panel 2.

5) Mount the instrument panel 1 on the instrument panel support bracket 1B and the dash panel 3.

6) Inker sensor (not shown), and

10) Mount the cluster lid 31 on the instroer 30.

As described above, in the assembling work, since various parts are individually connected to the bracket on the vehicle body side by bolts and the like, there are a large number of attachment points, and moreover, there are a lot of difficult works. It takes a long time to complete, and the assembling work in front of the front seats in the passenger compartment is extremely difficult.

For this reason, for example, in the past, for example
As disclosed in JP-A-10,945, a panel box is attached to a case of an air conditioning unit and accessory parts are installed in the panel box in order to collectively incorporate various components to be mounted in front of a passenger compartment front seat. Some of these accessories are mounted on the vehicle body via an air conditioning unit.

[0023]

SUMMARY OF THE INVENTION However, when the accessory parts are attached to such a panel box and then they are collectively attached to the air conditioning unit, one component for mounting on the vehicle becomes large and enormous. There is a possibility that workability may be impaired only by having a heavy weight. Especially, by simply integrating the parts that must be stored in a small storage space in front of the front seat in the vehicle compartment, the number of installation work is reduced, but it becomes difficult to balance the weight of the entire unit assembly. Moreover, it is said that heavy work has to be stored in a narrow space with a large part lifted slightly above the floor panel, and it has not been completely eliminated. It's a reality.

Therefore, the present invention provides a mounting structure for a unit assembly including a vehicle air conditioner capable of easily storing a large modularized heavy component in a narrow storage space in front of a front seat of a passenger compartment. With the goal.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing a mounted state of a unit assembly including a vehicle air conditioning unit according to an embodiment of the present invention, and FIG. 2 is each component of a unit assembly including a vehicle air conditioning unit according to the embodiment. And an exploded perspective view showing components in the vicinity thereof, FIG. 3 is a schematic perspective view showing a state in which only a heater unit of an air conditioner for a vehicle is mounted, and FIGS. 4A, 4B, and 4C are air conditioners for a vehicle. FIG. 5 is a schematic side view showing a state in which only a heater unit of the apparatus is attached for each process, and FIG. 5 is a side view showing an assembled state of a unit assembly including a heater unit. The same members as those shown in FIGS. The code is attached.

The unit assembly A of this embodiment generally includes a heater unit 17 in the vehicle air conditioning unit 10.
The heater unit 17 is provided with an instroker 30, a cluster lid 31, an audio device 40, and the like.

As shown in FIG. 7, the vehicle air conditioning unit 1
0 is an intake unit 11, a cooler unit 12,
The heater unit 17 is composed of three units, and these three units are provided in front of the front seat Fs in the vehicle interior R formed by the dash panel 3, the floor panel 2, etc., as shown in FIG. Moreover, it is stored in an extremely narrow storage space 5 below the instrument panel 1.

In this vehicular air conditioning unit 10, a heater unit 17 is usually provided at a substantially central portion in the vehicle width direction so that temperature-controlled air is evenly branched and blown out to the left and right in the vehicle width direction. There is. Therefore, in the case where the unit assembly A is modularized, the heater unit 17 is the center, and the instroker 30 provided in the central portion of the front of the front seat in the passenger compartment and the opening 30a of the instroyer 30. It is preferable to integrate the audio equipment 40 such as a tape deck and a radio installed in the.

In addition to these, Instro 30
The center console 42 and the instrument panel mounting bracket 1B extending from the rear to the inside of the vehicle can be mounted on the instrower 30. Further, an aspirator duct Das may be added to these to further increase the size. .

In this case, the instroker 30 may be connected to the heater unit 17 by a screw or the like, and the audio device 40 may be housed in the opening 30a of the instroyer 30 and fixed by a screw or the like. Further, the center console 42 is configured to be connected to the instroyer 30 or the heater unit 17 by fitting in a concavo-convex shape, and at the time of this connection, the rear duct Dr provided inside the center console 42 and the unit case 17 of the heater unit 17.
If it is configured to be connected together with the rear duct Dr extending from the a side, the rear duct Dr can be connected to each other only by connecting the center console 42 and the unit case 17a, and only the rear duct Dr can be connected. There is no need to do it separately.

However, when the center console 42 is combined with the unit assembly A and the size becomes too large, only the center console 42 may be separately connected to the heater unit 17 by concavo-convex fitting.

Since the unit assembly A formed in this way is only a part provided at the substantially central portion in the vehicle width direction, even if the unit assembly A has a slightly increased weight due to modularization, with respect to the withstand load. Is no problem. In particular, a bulge portion, a so-called tunnel portion 2a, is formed in a substantially central portion of the floor panel 4 in the vehicle width direction in order to increase the strength of the floor panel 2. The tunnel portion 2a has a considerable strength. Therefore, the unit assembly A is supported on the tunnel portion 2a,
Moreover, there is no problem even if it is moved while being supported.

Therefore, in this embodiment, the tunnel section 2
On a, a pair of brackets 2B (see FIG. 3) for fixing the heater unit 17 and, in some cases, a pair of brackets 42B for fixing the center console 42.
(See FIG. 5), the brackets 2B and the like support the load of the unit assembly A, and the unit assembly A is transported or moved to a predetermined position. By modularization, various devices are centrally provided. The workability of mounting the heavy unit assembly A is improved.

However, merely supporting the load of the unit assembly A on the bracket 2B or the like is not effective in improving the mounting workability. Therefore, in this embodiment, further, a flat support surface 17b for receiving a load is formed on the lower surface of the unit case 17a of the heater unit 17, which is the main part of the unit assembly A, so as to have a predetermined length L. At the same time, a mounting piece T connected to the bracket 2B by a fixture K such as a bolt is provided at the end of the support surface 17b.

Particularly, the support surface 17b is the unit case 1
It is preferable to form a concave shape on both sides of the lower surface of 7a. In this way, the bulging portion formed between the support surfaces 17b serves as a guide for sliding contact with the bracket 2B and the like, and the unit assembly A can be moved into the storage space 5 and stored therein, so that the mounting workability is improved. Moreover, if the bulging portion between the support surfaces 17b is a part of the rear duct Dr, the unit case 1
Compared with the case where the rear duct Dr is separately provided on the 7a, not only space is advantageous, but also duct connection is simplified.

The shape of the tip of the bracket 2B is preferably slightly inclined as shown in the figure in consideration of workability with connection to the bolt, but should be flat in consideration of the transportation of the unit assembly A. Is preferred.

Any number of brackets 2B for fixing the heater unit 17 and the center console 42 may be used as long as they are provided along the tunnel portion 2a, but after mounting work, they are attached to the vehicle body. Since the heater unit 17 and the center console 42 are fixed, it is not preferable to provide an unnecessarily large number.

The operation of this embodiment will be described. First, the heater unit 17, the intro 30, and the audio device 40
Are integrally assembled to form a modular unit assembly A. The unit assembly A may be a larger unit assembly A in which the instrument panel mounting bracket 1B, the aspirator duct Das (see FIG. 6), the center console 42, the rear duct Dr and the like are further combined.

The unit assembly A formed in this manner is considerably heavy in weight, but depending on the case, it is put into the vehicle compartment by using a hanging robot or the like, and the supporting surface 17b formed on the unit case 17a. Is placed on a bracket 2B or the like that is erected on the tunnel portion 2a of the floor panel 2, and the entire weight is supported by the bracket 2B and the like.

Then, the unit assembly A is slid on the bracket 2B or the like and moved into the storage space 5, and the mounting piece T provided at the end of the supporting surface 17b and the bracket 2B or the like are fixed by the fixture K. If connected, the worker does not have an unnatural posture.

In this case, therefore, even if the unit assembly A is heavy, the overall weight balance of which is deteriorated by combining various parts, the bracket 2
Since it is moved to the inside of the storage space 5 while being supported by B or the like, there is no difficulty and the workability is significantly improved.

After fixing, the instrument panel 1 is attached to the instrument panel mounting bracket 1B. If the instrument panel 1 is retrofitted, the mounting work can be performed in the storage space 5 which has a relatively large mounting space, so that the labor of the work is slightly reduced.

Next, in the case of the unit assembly A in which the heater unit 17 and the center console 42 are not united, the heater unit 17 and the center console 42 are connected and both rear ducts Dr are connected. In this case, since the unit assembly A does not initially become a long component, the unit assembly A can be mounted relatively easily.

The present invention is not limited to the above-described embodiments, but can be variously modified and used within the scope of the claims. For example, in the above-described embodiment, the heater unit is modularized as the main part, but in some cases, the cooler unit or the intake unit may be modularized as the main part, and the unit case 17a of the heater unit 17 may be used. The support surface 17b formed on the above may also be formed on other parts depending on the case.

[0047]

As described above, according to the first aspect of the invention, a modular unit assembly in which at least an instroker and an audio device are attached to the heater unit is modularized, and a narrow storage space is provided in front of the front seat. When it is housed inside, the support surface formed on the heater unit is once placed on a bracket that is erected on the floor panel, and the entire weight is supported by the bracket. Since the support surface is used as a guide to move into the storage space, and the mounting piece and the bracket provided at the end of the support surface are connected by the fixture,
Even a unit assembly of a heavy object having a poor overall weight balance can be easily accommodated and fixed in a narrow accommodation space, so that not only the mounting workability is improved but also difficult work can be eliminated. According to the second aspect of the present invention, since the bulging portion between the supporting surfaces serves as the rear duct, not only space is advantageous, but also the duct connection is simplified. According to the invention as set forth in claim 3, since the unit assembly has the center console, almost all the parts in the central portion in the vehicle width direction can be collectively attached, and modularization can be further promoted.
Assembly workability is greatly improved. According to the invention described in claim 4, after the heavy unit assembly is slidably moved into the storage space and fixed, the vehicular air conditioning unit and the center console can be connected, and a long component is also simple. Can be installed on. According to the invention of claim 5, the rear duct inside the center console and the unit case side duct are connected only by the connection between the center console and the unit case, and only the center console side rear duct and the unit case side duct are connected. There is no need to separately connect According to the sixth aspect of the invention, since the unit assembly has the instrument panel mounting bracket, modularization can be promoted and assembly workability is improved. According to the invention described in claim 7, since the instrument panel can be mounted on the instrument panel mounting bracket after the unit assembly is mounted, the relatively small storage space is narrowed by the instrument panel when mounting the unit assembly. It is possible to make a comparatively large storage space.
