Aiming at the defects of the prior art, the utility model provides an air conditioner air duct in a sheet metal cavity, which solves the problem that in order to realize the blowing of heads of two rows, some vehicle rabbets are added with the air conditioner air duct in an upper boundary beam plaque to guide the air flow of an air conditioner to the two rows; and then the air flow on one side is guided to the other side through the flow guide pipe in the ceiling of the top beam. Limited by some back-slip type models, the head space of two rows of passengers is small, and if an air conditioning pipeline is additionally arranged, the head space of the passengers is further compressed, and riding comfort is reduced. The air conditioning pipeline needs a certain section size, otherwise, the air flow is not smooth, and the air conditioning pipeline is similar to the problem of dummy.
(II) technical scheme
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides an inside air conditioner wind channel of panel beating cavity, includes skeleton and last skeleton down, it installs to go up the skeleton the top of skeleton down, go up the skeleton with be formed with the wind channel down between the skeleton, go up the skeleton with the gap department that the skeleton is connected down is filled with foaming sealing strip, just go up the top of skeleton with the film filling groove has all been seted up to the bottom of skeleton down, the inside in film filling groove is filled with the bonding film.
Preferably, the foaming sealing strip is made of EVA material through coating, electrophoresis, baking and foaming;
by adopting the technical scheme, the joint of the upper framework and the lower framework has good tightness.
Preferably, the lower framework and the upper framework are both formed by injection molding of nylon fiber-added frameworks;
through adopting above-mentioned technical scheme, nylon skeleton adopts the structure of moulding plastics to follow panel beating profile design, can accomplish the cross-section maximize, strengthens ventilation.
Preferably, the adhesive film is formed by coating, electrophoretic baking and foaming an epoxy resin structural film;
through adopting above-mentioned technical scheme, firmly bond nylon pipeline and panel beating together, ensure that there is not relative motion in the vehicle driving process, can not produce friction abnormal sound, and nylon glass fiber skeleton and epoxy structural adhesive play the effect of strengthening to top crossbeam panel beating together, increase automobile body safety.
(III) beneficial effects
The utility model provides an air conditioner air duct in a sheet metal cavity. The beneficial effects are as follows: the air conditioner air duct inside the sheet metal cavity breaks through the traditional scheme of installing the air guide pipe on the inner side of the final assembly interior trim part. The nylon air conditioning pipeline is embedded in the top beam in the welding workshop instead. Not only do not encroach on the head space of two rows, can also make full use of the sectional area of panel beating die cavity realize ventilation cross-section size's maximize, simultaneously, can also play certain enhancement effect to the top crossbeam, nylon skeleton adopts the structure of moulding plastics along with panel beating profile design, can accomplish the cross-section maximize, strengthens ventilation, and EVA and epoxy structural adhesive after the foaming have thermal-insulated performance, can replace the thermal-insulated cotton of conventional air pipe outer parcel, reduce cost.
