Description

Technical Field

[0001] The utility model belongs to the field of blow-molded air ducts, and specifically relates to blow-molded air ducts. Background Art

[0002] Blow-molded air duct is one of the auto parts. The air duct is a system used for air delivery and distribution. As the connecting pipe of the auto air conditioning system, the air duct delivers the air after cooling, heating, ventilation and air purification to the car, playing a vital role.

[0003] The existing Chinese patent with publication number CN211032481U discloses a novel multi-directional fastening structure front bumper blow-molded air duct, including an air duct body, an air inlet, a bumper and a wheel cover, wherein the right end of the air duct body is equipped with an air inlet, the left end of the air duct body is fixed with a wheel cover, and the top and both sides of the air duct body are fixed with a second fixing frame. The utility model utilizes a fixing bracket to be inlaid on multiple surfaces of the air duct, and adopts a combination of injection molding and blow molding technology to solve the limitation that the fastening points of the existing ordinary blow-molded air duct are only arranged at the parting line position, so that the air duct branch can be matched and fastened in multiple directions, meeting the fastening requirements of the air duct for more stable fastening, improving the practicality of the air duct, solving the problem that the existing second fixing frame and the third fixing frame are inconvenient to align and fix, making the air duct body simpler and more convenient to fix, and improving the convenience of operation when fixing the air duct.

[0004] With respect to the above-mentioned related technologies, the second fixing frame and the third fixing frame can be aligned and then fixed, which is convenient for installation. However, during the use of the blow-molded air duct, the air duct itself has weak deformation resistance and is prone to deformation when under pressure, which in turn causes the air duct to be unable to be used normally and easily causes uneven air flow.

[0005] So we proposed blow-molded air ducts to solve the problems mentioned above. Utility Model Content

The protective buckle plate, the protective plate and the thickening plate all wrap the air duct body, which can achieve the purpose of protection and prevent the air duct body from being deformed.

[0008] Preferably, a first interface portion and a second interface portion are provided on one side of the air duct body, and a mounting plate is provided on the outer side of the first interface portion, which can be assembled and fixed by cooperation of the mounting plate and bolts, and groove portions are evenly distributed on one side of the air duct body.

[0009] Preferably, the surface of the air duct body is evenly distributed with transverse reinforcing ribs and vertical reinforcing ribs, and the transverse reinforcing ribs and vertical reinforcing ribs are staggered with each other to form a grid shape, which can enhance the strength of the air duct body.
