Abstract

An air duct of a passenger car comprises a lower fixed edge, an upper fixed edge, a lower air duct section, an upper air duct section, an access door, a door lock, a transparent panel, a second hinge, a light guide plate and an elastic pressing piece. The lower fixed edge and the upper fixed edge are connected with a car body frame for mounting of the air duct. The lower air duct section is connected with the lower fixed edge. The upper air duct section is connected with the upper fixed edge. The upper end of the access door is hinged to the upper air duct section through a first hinge, and the lower end of the access door is connected with the lower air duct section in an opening mode. The access door comprises a door frame formed by connecting an upper door section, a door end section and a lower door section. The door lock is mounted on the lower door section of the door frame. The transparent panel is connected with the upper door section, the door end section and the lower door section of the door frame. The first end of the second hinge is connected with the upper door section of the door frame. The light guide plate is located on the side, close to the air duct, of the transparent panel, and the first end of the light guide plate is hinged to the other end of the second hinge. The elastic pressing piece is connected with the lower door section of the door frame and used for pressing the other end of the light guide plate and can be opened.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a passenger car air duct integrating ventilation, advertising and lighting. Background technique [0002] Passenger car air duct is an air duct installed at the intersection of the roof frame and side eaves frame of the passenger car for air temperature adjustment and ventilation in the compartment. It generally includes roof racks, side eaves frames, suspension beams and air duct components. The roof frame and the side eaves are connected at a certain angle, one end of the suspension beam is fixedly connected to the roof frame, and the other end is fixed to the side eaves; the air duct assembly is placed obliquely between the roof frame and the side eaves, Top frame, side eaves connection. Most of the current passenger car air ducts are integral parts, and are arranged along the length direction of the carriage, which is very inconvenient for cleaning, repairing and replacin...
