[0022] like Figures 1 to 6 The structure of a foot-blowing air duct for a car shown in the figure comprises a carpet 1 and a main air duct pipe 3. The left and right sides of the carpet 1 are both provided with foot-blowing air duct openings 11. The left and right sides of the main air duct pipe 3 are both branched with a group of secondary air duct pipes 31. The ends of the secondary air duct pipes 31 are both branched with two groups of tertiary air duct pipes 32. The tertiary air duct pipes 32 are correspondingly arranged in the foot-blowing air duct openings 11. The foot-blowing air duct openings 11 are covered with an air outlet cover 2 with a grille 21. The grille 21 is arranged on the side of the air outlet cover 2 away from the outlet of the tertiary air duct pipe 32. The main air duct pipe 3, the secondary air duct pipe 31 and the tertiary air duct pipe 32 are connected to form an air duct pipe assembly. Several fixing parts 30 on the air duct pipe assembly are fixedly connected to the vehicle body floor by screwing.

[0023] Preferably, in combination with the above scheme, in order to facilitate the fixation of the tertiary air duct tube 32 to the air duct joint 4, the foot blowing air duct opening 11 is fixedly connected with the air duct joint 4, and the tertiary air duct tube 32 is riveted and fixed to the air duct joint 4 by rivets 5.

[0024] Preferably, in combination with the above solution, in order to facilitate the fixation of the air duct joint 4 and the air outlet cover 2, the air duct joint 4 is fixedly connected to the air outlet cover 2 via a mushroom buckle 6.

[0025] Preferably, in combination with the above solution, in order to prevent air leakage and ensure sufficient wind pressure, a sealing strip 7 is provided between the inner wall of the air duct joint 4 and the outer wall of the tertiary air duct pipe 32 .

[0026] Preferably, in combination with the above solution, in order to fix the air outlet cover 2 on the outer wall of the foot blowing air duct opening 11, the inner wall of the air outlet cover 2 and the outer wall of the foot blowing air duct opening 11 are fixedly connected by plastic welding.

[0027] Preferably, in combination with the above solution, in order to facilitate the fixing of the air outlet cover 2 and the carpet 1 together, the inner wall of the air outlet cover 2 is fixedly connected to the carpet 1 by plastic welding. A plurality of welding posts 23 are arranged at the lower edge of the air outlet cover 2, and the welding posts 23 can be melted by an ultrasonic welding head and welded to the carpet 1.

[0028] Preferably, in combination with the above scheme, Figure 7 As shown, the grille is composed of a horizontally arranged transverse grille plate 21 and an inclined longitudinal grille plate 22. The design of the transverse grille plate 21 can ensure that the air flows toward the foot, and the longitudinal grille plate 22 cooperates with it to not only prevent large foreign objects from falling into the air inlet, but also increase the structural strength.

[0029] Preferably, in combination with the above solution, in order to disperse the wind and improve the comfort of blowing the feet, the three-level air duct 32 is arranged on the left and right sides of the end of the two-level air duct 31 to form a Y-shaped structure. The Y-shaped bifurcated structure can further prevent larger foreign objects from falling into the air duct.
