Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a duct mounting structure for mounting, for example, an overhead type rear air conditioner to a roof of a vehicle body.
[0002]
[Prior art]
Conventionally, for example, as shown in FIG. 4, the air conditioning duct is attached to the hole 122 of the reinforcement 121 fixed to the roof panel 111 in advance by aligning the hole 132 of the duct 131 with the clip 171 and fixing it in advance. After the hole 152 of the molded ceiling 151 to which the bracket 141 is fixed is aligned with the hole 123 of the reinforcement 121 and fixed by the clip 181, the claw 162 of the garnish 161 that is a grill part forming the air outlet is inserted into the hole 153 of the molded ceiling 151. The garnish 161 is fixed by being hooked on the hole 142 of the bracket 141 via
[0003]
Alternatively, as shown in FIG. 5, the duct 231 and the bracket 241 are respectively fixed to the molded ceiling 251 in advance, and then the garnish 261 that is a grill part in which the air outlet is formed is fixed by the claw 262, and the hole 252 of the molded ceiling 251 is Is fixed with a clip 281 in accordance with the hole 222 of the reinforcement 221 fixed to the roof panel 211 in advance.
[0004]
[Problems to be solved by the invention]
However, in the mounting structure shown in FIG. 4, there are three line strokes: duct mounting, ceiling mounting, and grill mounting, and workability is poor. In addition, the duct and the molded ceiling are assembled independently in the reinforcement. There was a problem that the accuracy of alignment between the hole of the duct and the hole of the molded ceiling was not achieved. Further, in the mounting structure shown in FIG. 5, since the weight of the duct is supported only by the molded ceiling, there is a possibility that the molded ceiling bends during parts transportation or hangs down when mounted on the vehicle body, which is not preferable.
The present invention has been made in view of such a situation, and an object of the present invention is to provide a duct mounting structure that can be easily assembled and can improve product quality.
[0005]
[Means for Solving the Problems]
The duct mounting structure according to the present invention is made in order to solve such a problem. After the duct having the mounting portion to the roof panel is fixed to the rear surface of the molded ceiling, the duct is provided on the molded ceiling and the duct. A grille is attached to the opening, and a molded ceiling to which the duct is bonded is attached to the roof panel via the duct attachment portion. The attachment portion of the duct is a bracket attached to the duct, and the bracket There it is reinforce the formed ceiling by crossing the duct.

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a duct mounting structure according to the present invention will be described with reference to the drawings. The duct mounting structure according to one embodiment of the present invention is applied to the four-wheeled vehicle shown in FIG. 1, and more specifically, to the duct 40 connected to a cooling unit (not shown) of an overhead type rear air conditioner. Is.
[0008]
This embodiment is an attachment structure as shown in FIG. 2 or FIG. 3, and the duct 40 has an inverted trapezoidal outer shape in cross section, and an attachment hole 41 is provided in the upper surface portion 43. The bracket 30 is attached to the upper surface portion 43 of the duct 40 so as to intersect the duct 40 with the screw 81 using the attachment hole 41. Each bracket 30 is provided with attachment holes 31 at both ends, and the diameters and inter-hole dimensions of the attachment holes 31 correspond to the attachment holes 21 of the roof reinforcement 20 fixed to the roof panel 10. ing. In the duct 40, a plurality of holes 42 are formed in one oblique side portion along the longitudinal direction.
[0009]
The molded ceiling 60 is provided with an attachment hole 61 corresponding to the attachment hole 31 of the bracket 30, and a convex portion 63 projecting to the surface side is provided in a straight line shape. The convex portion 63 forms a space for the duct 40. A plurality of holes (openings) 62 are formed in the convex portion 63.
[0010]
The bracket 50 is a plate-like member, and a hole 51 corresponding to the hole 62 of the molded ceiling 60 is formed. As shown in FIG. 2, the bracket 50 is fixed to the back surface of the molded ceiling 60.
[0011]
The garnish (grill) 70 is subjected to a design treatment on the surface, and has a plurality of claws 71 on the back surface. As shown in FIG. 2, the claw 71 is locked in the hole 51 of the bracket 50.
[0012]
Next, the mounting method of the component in this embodiment is demonstrated using FIG.2 and FIG.3. First, the mounting hole 32 of the bracket 30 is aligned and fixed to the mounting hole 41 of the duct 40 with the screw 81, and the duct 40 and the bracket 30 are fixed to the molded ceiling 60. Next, (2) the claw 71 of the garnish 70 is hooked and fixed to the hole 51 of the bracket 50 through the hole 62 of the molding ceiling 60. Then, (3) the mounting hole 61 of the molded ceiling 60 and the mounting hole 31 of the bracket 30 are aligned with the mounting hole 21 of the reinforcement 20 fixed in advance to the roof panel 10 and fixed by the clip 82. That is, the bracket 30 is fastened together with the clip 82.
[0013]
In the present embodiment, as described above, the line stroke is only (3), the workability in the line is improved, and the duct 40 and the formed ceiling 60 are assembled at once in the line stroke (3). It is possible to reduce the process in the line. Further, by fixing the duct 40 to the molded ceiling 60, the positional accuracy of the holes 42, 51, 62 is improved, and the assembly accuracy of the garnish (grill) 70 is improved. Further, since the weight of the duct 40 is supported not only by the molded ceiling 60 but also by the roof panel 10 via the bracket 30 and the roof reinforcement 20, compared with the case of the prior art shown in FIG. When carrying the ceiling or the like, the bracket 30 can prevent bending due to the weight of the duct and can prevent drooping when the vehicle body is attached. Compared to the case of the prior art shown in FIG. 4, the duct 40 and the molded ceiling 60 are fastened together, so the number of fixing clips is reduced and the number of parts can be reduced.
[0014]
【The invention's effect】
In the duct mounting structure according to the present invention, after fixing the duct having the mounting portion to the roof panel to the back surface of the molded ceiling, a grill is attached to the opening provided in the molded ceiling and the duct, and the duct is bonded. Since the molded ceiling is attached to the roof panel via the duct attachment part, the process and the number of parts can be reduced by attaching to the roof panel at one time. Assembling accuracy can be improved.
[0015]
The mounting portion of the duct is a bracket attached to the duct, and when the molded ceiling is reinforced by intersecting the duct, the deformation of the molded ceiling due to the weight of the duct can be prevented.
