Description

TECHNICAL FIELD

[0001] The utility model relates to the field of passenger car built-in, concretely relates to a passenger car air duct structure. BACKGROUND

[0002] The setting mode of the passenger car air duct in the prior art is to fix the passenger car air duct by welding the air duct hanger on the air duct angle iron, which can ensure the firmness and reliability of the air duct of the passenger car, but has strict requirements on the material of the air duct, which is limited to the side wall frame of iron or steel.

[0003] When the air duct hanger is welded on the carbon fiber vehicle body, the high temperature generated by welding can cause the surface of the carbon fiber vehicle body to be oxidized and ablated. Although the water spraying method is usually used to reduce the temperature, the damage to the vehicle body cannot be completely avoided. In addition, the lower profile of the air duct is fixed by riveting on the other side of the air duct angle iron, and the high temperature of welding can cause oxidation, cracking or even loosening of the riveting point, resulting in insecure riveting. Although the position of the riveting port can be changed (such as increasing the spacing), the strength of the riveting fixation may still be insufficient, causing the lower profile of the air duct to shake or even fall off. When the air duct hanger is welded on the aluminum alloy vehicle body, the welding difficulty between aluminum alloy and iron or steel material is high, and the high temperature generated by welding can even damage the structural integrity of the aluminum vehicle body.

[0004] The air duct hanger in the prior art also has a bolt connection mode to be directly fixed on the vehicle body roof, but in order to ensure the firm fixation of the air duct hanger, the corresponding connection port or fixing support needs to be increased, which will increase the design and processing difficulty of the frame.
