[0023] The upper end and rear side of the front windshield lower crossbeam assembly 3 are respectively provided with a fourth ventilation port 301 and a fifth ventilation port 302 that are connected to the first ventilation cavity 30.

[0025] The upper end of the front section 6 of the middle channel is provided with a sixth ventilation opening 601 that is connected to the second ventilation cavity 60. The sixth ventilation opening 601 is connected to the third ventilation opening 202.

[0026] The air conditioning duct structure also includes a second ventilation pipe 5, the upper end of which is connected to the third ventilation port 202, and the lower end of which is connected to the sixth ventilation port 601.

[0027] The front and rear sides of the front crossbeam 7 of the front seat are respectively provided with a seventh ventilation port 701 and an eighth ventilation port 702 that communicate with the third ventilation cavity 70. The seventh ventilation port 701 is connected to the second cavity 60, and the eighth ventilation port 702 is connected to the fourth ventilation cavity 80.

[0028] The front side and upper end of the rear crossbeam 9 of the front seat are respectively provided with a ninth ventilation port 901 and a tenth ventilation port 902 that are connected to the fifth ventilation cavity 90.

[0030] The upper left and right sides of the rear crossbeam 9 of the front seat are provided with eleventh ventilation openings 903 that are connected to the fifth ventilation cavity 90. The eleventh ventilation opening 903 is a foot blowing air duct.

[0031] In order to defrost the front windshield and avoid affecting the observation of the left and right side rearview mirrors, the left and right sides of the front windshield lower crossbeam assembly 3 are respectively connected to one end of a set of fourth ventilation pipes 12, and the fourth ventilation pipes 12 are connected to the first ventilation cavity 30; a set of thirteenth ventilation openings 102 are provided on both the left and right sides of the instrument panel assembly 1, and the thirteenth ventilation openings 102 are connected to the other end of the fourth ventilation pipes 12.

[0032] The present invention can realize four air ducts. The first air duct passes through the second ventilation port 201, the first ventilation pipe 4, the fifth ventilation port 302, the first ventilation cavity 30, the fourth ventilation port 301, and the first ventilation port 101 of the HVAC assembly 2 in sequence. This air duct is used for defrosting the front windshield 200. The second air duct passes sequentially through the second vent 201, the first ventilation pipe 4, the fifth vent 302, the first ventilation cavity 30, the fourth ventilation pipe 12, and the thirteenth vent 102 of the HVAC assembly 2. This air duct is used to defrost the front windshield. The third airflow passes sequentially through the third vent 202, the second ventilation pipe 5, the sixth vent 601, the second ventilation cavity 60, the seventh vent 701, the third ventilation cavity 70, the eighth vent 702, the fourth ventilation cavity 80, the ninth vent 901, the fifth ventilation cavity 90, and the twelfth vent 1101 of the HVAC assembly 2, and is used to blow air onto the upper body of rear passengers.

[0033] Since this embodiment uses the internal cavity of the lower crossbeam assembly 2 of the windshield as an air duct, the air duct on the original instrument panel assembly 1 is eliminated, thus saving space below the instrument panel assembly 1, reducing the installation height of the instrument panel assembly 1, and expanding the driver's field of vision; even if the tilt angle of the windshield 200 is made smaller, the lower part of the windshield 200 can be effectively defogged without the need to use the more powerful exhaust HVAC assembly 2; if the installation height of the instrument panel assembly 1 is not reduced, more intelligent components, such as domain controllers, redundant units, wiring harnesses, etc., can be installed below the instrument panel assembly 1.

[0034] In this embodiment, the cavities inside the front section 6 and rear section 8 of the central channel below the armrest box assembly 11 are used as air ducts, eliminating the original ventilation ducts below the armrest box assembly 11 and the ventilation ducts under the seat. This saves space below the armrest box assembly 11 and under the seat, allowing for the installation of more intelligent components, such as redundant power systems and autonomous driving domain controllers. It also allows the armrest box to be made larger, accommodating more items.

[0035] In this embodiment, the first ventilation pipe 4, the second ventilation pipe 5, the third ventilation pipe 10, and the fourth ventilation pipe 12 can all be made of plastic. In order to achieve effective sealing, sealing rings can be set between each ventilation pipe and each ventilation opening to achieve a sealing effect. The electrophoretic leakage holes on the sheet metal associated with each air duct can also be sealed with rubber plugs.
