Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioning rear duct structure for leading out temperature-controlled air from a vehicle air conditioning system to the rear seat side.

[0002]

2. Description of the Related Art For example, in a vehicle such as an automobile, an air conditioner is used to adjust the temperature and humidity in the passenger compartment. This air conditioner introduces cold air, hot air, and mixed air thereof into the vehicle interior to adjust the temperature inside the vehicle interior.

In this case, a rear heater duct is used to supply temperature-controlled air, for example, warm air, to the rear seat side in the passenger compartment. One end of this rear heater duct is connected to the warm air outlet of the air conditioner, and the other end is inserted into a cross member provided on the vehicle body to open the air discharge port thereof toward the rear seat.

[0004]

However, as shown in FIG. 4, in the conventional rear heater duct 2, when the air discharge port 2a side is inserted into the hole 4a of the cross member 4,
The warm air introduction port 2b side of the rear heater duct 2 easily interferes with the peripheral parts 6. Therefore, the operator must insert the rear heater duct 2 on the air discharge port 2a side into the hole 4a of the cross member 4 while avoiding the peripheral parts 6.

However, this kind of work is considerably complicated and requires a considerable amount of experience, and in particular, the air discharge port of the rear heater duct 2 inserted into the hole 4a of the cross member 4 is required. An excessive load is applied to the 2a side, and breakage or the like is likely to occur. For this reason, it has been pointed out that it is difficult to improve the efficiency of the whole assembling work of the rear heater duct 2, and further, it takes time for the layout at the design stage.

The present invention solves this kind of problem, and an object of the present invention is to provide a rear duct structure for an air conditioner of a vehicle, which has a simple structure, enables efficient rear duct assembly work, and has a high degree of freedom in design. And

[0007]

In order to solve the above-mentioned problems, the present invention is provided with a first duct portion, one end of which is connected to an air outlet portion of a vehicle air conditioner, and the air outlet portion. A second duct portion, which has an air outlet for ejecting air to the rear seat side and is inserted into a cross member of the vehicle body, is connected by a flexible connecting member. Therefore, the first duct portion and the second duct portion can be bent to each other, the degree of freedom is improved, and the whole rear duct assembling work is easily and efficiently performed.

Is a side view of the rear duct structure 10, and FIG.
3 is a plan view of the rear duct structure 10. FIG.

The rear duct structure 10 is a vehicle air conditioner 1.
The first duct part 1 having one end connected to the second air lead-out part 14.
6 and air discharge ports 18a to 18d for discharging the air introduced from the air outlet 14 to the rear seat side (not shown).
Second duct portions 24a to 24d, which are inserted into the cross member 22 provided in the vehicle body 20, and the other end of the first duct portion 16 and the second duct portions 24a to 24d are bendable with respect to each other. Bellows member (flexible connection member) 26 for connection
a to 26d. As shown in FIG. 2, a front seat 29 is arranged on the cross member 22 via a seat rail 27.

At one end of the first duct portion 16, there is provided a cylindrical body portion 28 that opens vertically upward and directly engages with the air outlet portion 14, and the first duct portion 16 is
It is branched into two in the vehicle width direction (direction of arrow H), and connection portions 30a to 30d for mounting one end portions of the bellows members 26a to 26d are provided at respective end portions thereof.

The second duct portions 24a to 24d are inserted into the hole portions 32a to 32d formed in the cross member 22, and the bellows members 26a to 26d are provided at the ends opposite to the air discharge ports 18a to 18d. The other end is attached. The bellows members 26a to 26d are made of, for example, a resin material. An elastic body such as synthetic rubber may be used instead of the bellows members 26a to 26d.

The rear duct structure 10 thus constructed
The work of assembling the above to the vehicle body 20 will be described below.

First, as shown by the chain double-dashed line in FIG. 2, the first duct portion 16 is largely inclined upward, while the second duct portions 24a to 24d are laid on the first duct portion 26a to 26d via the bellows members 26a to 26d. The duct portion 16 is bent.

Next, the first duct portion 16 is connected to the bellows member 2.
The second duct parts 24a to 24d are moved rearward while being swung downward (direction of arrow A) around 6a to 26d as fulcrums (direction of arrow A '), and the second duct parts 24a to 24d are formed in the hole part 3 of the cross member 22.
The first duct portion 16 is attached to the set position at the same time as being inserted into the 2a to 32d and arranged at the set position. Then, after the first duct portion 16 is arranged substantially parallel to the floor 20a of the vehicle body 20, the first duct portion 16 is adjusted in a direction away from the cross member 22 (direction of arrow B) as necessary. And
The air outlet 14 is connected to the tubular portion 28 of the first duct 16. As a result, the assembling work of the rear duct structure 10 is completed.

As described above, in this embodiment, the first duct portion 16 and the second duct portion 2 which constitute the rear duct structure 10 are formed.
4a to 24d are foldably connected to each other via bellows members 26a to 26d. Therefore, with the first duct portion 16 maintained in a desired posture, the second duct portion 2
4a to 24d are holes 32a to 32d of the cross member 22.
After being inserted into, the first duct portion 16 alone can be swung. Therefore, the rear duct structure 10 is attached to the vehicle body 20.
It is possible to obtain an effect that the work of assembling to is easily and efficiently performed.

Moreover, since the first duct portion 16 and the second duct portions 24a to 24d are freely bendable, when the rear duct structure 10 is assembled to the vehicle body 20, the first duct portion 16 and the second duct portion are assembled. Excessive load does not act on the portions 24a to 24d. This has the advantage that it is possible to effectively prevent breakage of the first duct portion 16 and the second duct portions 24a to 24d.

Further, the rear duct structure 10 can be easily assembled even in a relatively small space. Therefore, the effective space in the vehicle compartment can be effectively utilized, and the installation positions of the peripheral parts are not restricted.

Further, with the second duct portions 24a to 24d inserted in the cross member 22, the first duct portion 16 is positioned a predetermined distance in the direction of arrow H in FIG. 3 via the bellows members 26a to 26d. It is adjustable. Thereby, the first
Connection work between the duct portion 16 and the vehicle air conditioner 12 is smoothly performed.

[0019]

As described above, in the vehicle air conditioning rear duct structure according to the present invention, the cross member provided on the vehicle body is provided with respect to the first duct portion of which one end is connected to the air lead-out portion of the vehicle air conditioner. Since the second duct portion inserted into the first duct portion is connected via the flexible connecting member, the first duct portion and the second duct portion are bendable with respect to each other. This allows
The degree of freedom is improved, and even in a narrow space, an excessive load does not act on the rear duct itself, and the assembling work of the rear duct is easily and efficiently performed.
