Instrument panel-air conditioning duct assembly for vehicle

Abstract

An instrument panel-air conditioning duct assembly for vehicle (1), comprising an instrument panel (2) having a synthetic resin front side formed panel (3) and a synthetic resin rear side formed panel (4) and an air conditioning duct (10), wherein the rear side formed panel (4) is vibratingly welded to the front side formed panel (3) through a plurality of projected parts (5) positioned on the surface of the rear side formed panel (4) opposed to the surface of the front side formed panel (3), clearances for insulation (6) being provided between both formed panels (3, 4), the air conditioning duct (10) is formed, as a part of the peripheral wall thereof, of a part (22) of the rear side formed panel (4), whereby the man-hour of the production of the assembly can be reduced.

Description

technical field [0001] The present invention relates to a conduit assembly for an instrument panel air conditioner for a vehicle. Background technique [0002] Originally, as such an assembly, an assembly formed by vibration welding a synthetic resin instrument panel and a synthetic resin air-conditioning duct is known. In this case, the instrument panel is composed of an inner formed panel formed by injection molding and a skin bonded to its surface by an adhesive. Also, the air conditioner duct is formed by blow molding, has a plurality of branched duct portions, and pinch-sealed portions connected to these duct portions serve as welded portions. [0003] However, in the conventional instrument panel, the adhesive coating operation of applying the adhesive to the inner formed plate and the foam molding operation for bonding the skin are required, and the curing time of the adhesive is required. , Therefore, there is a problem that the number of man-hours for the manufact...

AI Technical Summary

Problems solved by technology

[0003] However, in the conventional instrument panel, the adhesive coating operation of applying the adhesive to the inner formed plate and the foam molding operation for bonding the skin are required, and the curing time of the adhesive is required. , therefore, there is a problem that the number of man-hours for the manufacture of the instrument panel and thus for the manufacture of the assembly is large

[0004] In addition, in the rear side forming plate, when forming a thick part, such as a protruding part for component attachment, etc. on the back side, a constriction corresponding to the thick part, that is, a concave part, is formed on the surface side of the back side forming plate, Since the skin follows its recesses, the uniformity of the surface of the dashboard is reduced, and there is a problem of impairing the commodity value of the assembly

[0005] In addition, in the original assembly, if the air-conditioning duct deviates from its original function, there will be redundant parts to be welded, so there is a problem of increased weight due to this.
