The terms "upper", "lower", "front", "rear", and the like, which refer to directions in this disclosure, refer to the vehicle itself. For example, "up" means toward the roof, and "down" means toward the bottom of the vehicle, and "front" means toward the head, and "rear" means toward the tail.

In the design of the related new energy automobile, the power assembly device is generally arranged at the lower part of a trunk of the automobile, a corresponding exhaust passage is not designed, part of hot air generated when the power assembly device is allowed circulates around the power assembly device, the working efficiency of the power assembly device is influenced, and part of hot air rises to the headrest part of the rear seat through the trunk, so that passengers in the rear seat feel uncomfortable.

An embodiment of the present disclosure provides a hot air discharge device, which includes a duct and at least one air outlet disposed on an outer surface of a center pillar of a vehicle facing a cabin, and discharges hot air generated by a powertrain device of the vehicle into the cabin through the duct via the at least one air outlet, so as to prevent the hot air from being gathered near the powertrain device, improve the work efficiency of the powertrain device, and reduce the possibility that the hot air is gathered in a headrest area of a rear seat, thereby reducing discomfort of a rear passenger.

Fig. 1 is a schematic partial structural view of a vehicle in which a hot gas exhaust device according to an embodiment of the present disclosure is provided, in which components of the hot gas exhaust device and positions of the hot gas exhaust device in the vehicle are shown. As shown in fig. 1, the hot gas exhaust means includes a passage, and at least one exhaust port 21. The duct includes a first sub-duct 1 and a second sub-duct 2, the first sub-duct 1 being connected at one end to an exhaust duct 30 of the power train unit for receiving hot gases generated by the power train unit. The other end of the first sub-passage 1 communicates with one end of the second sub-passage 2, the second sub-passage 2 is provided in a center pillar of the vehicle, and the exhaust port 21 is provided on an outer surface of the center pillar 20 facing the inside of the vehicle compartment, communicating with the second sub-passage 2. The hot gas discharge device forms an exhaust passage, and discharges hot gas generated by the power train device into the vehicle compartment through the exhaust duct 30 of the power train device, the first sub-duct 1, and the second sub-duct 2, and the exhaust port 21. In fig. 1, only one exhaust port 21 is shown, and those skilled in the art will appreciate that a plurality of exhaust ports 21 may be provided. The hot air exhaust device avoids hot air from being gathered near the power assembly device, improves the working efficiency of the power assembly device, reduces the hot air gathering in the headrest area of the seats in the back row, and reduces the discomfort of passengers in the back row.

In an embodiment, the first sub-channel 1 is defined by the rear foot board 10 and the vehicle body, specifically, the rear foot board 10 covers the bottom of the rear door frame, and a space between the rear foot board 10 and the bottom of the rear door frame is hollow, so as to form the first sub-channel 1. The rear foot pedal may be made of a certain rigid plastic material such as polypropylene (PP), ABS (terpolymer of acrylonitrile, butadiene and styrene), etc.

The rear seats are not shown in fig. 1 for clarity of the components of the hot gas exhaust device. Fig. 2 is a partial structural schematic view of a vehicle in which a hot gas exhaust device according to an embodiment of the present disclosure is provided, illustrating a position of the hot gas exhaust device in the vehicle.

In one embodiment, as shown in fig. 1 and 2, the exhaust port 21 is provided between the bottom end portion of the center pillar 20 and one-half of the center pillar in the height direction, for example, at a lower portion of the center pillar, i.e., a position near the bottom of the vehicle compartment, in other words, the exhaust port 21 is provided at a portion of the center pillar 20 away from the body cross member 40. Thus, the hot air discharged from the exhaust port 21 enters the lower middle portion of the vehicle cabin, and the passenger does not feel uncomfortable. In other alternative embodiments, the exhaust port 21 may be disposed in other portions of the center pillar, such as the middle or upper portion of the center pillar, and also serves to prevent hot air from being collected near the power unit, to improve the operating efficiency of the power unit, and to reduce hot air from being collected in the headrest area of the rear seat, thereby reducing the discomfort of the rear passenger.

In one embodiment, the exhaust port 21 is provided on the outer surface of the center pillar 20 facing the inside of the vehicle compartment in a direction substantially perpendicular to the side of the vehicle, that is, the exhaust port 21 is provided in a direction substantially perpendicular to the door, so that the exhaust port 21 exhausts the hot air to an intermediate position of the vehicle compartment away from the head and the tail of the vehicle. In this case, the exhaust port is formed in a relatively flat area of the outer surface of the center pillar 20, which facilitates manufacturing. In other embodiments, the exhaust port 21 may be disposed in other orientations.

Fig. 3 is a partial structural view of a center pillar according to an embodiment of the present disclosure, and fig. 4 is a cross-sectional view taken along line a-a in fig. 3. As shown in fig. 3 and 4, at least one of the exhaust ports 21 is provided with a plurality of obliquely arranged lateral barriers 22, and the plurality of obliquely arranged lateral barriers 22 may be arranged in parallel with each other. The plurality of lateral barriers 22 are inclined from top to bottom in the direction from the inside of the center pillar to the outside of the center pillar (i.e., in the vehicle compartment), and guide the discharged hot air from the exhaust port 21 toward the bottom of the vehicle compartment, i.e., in the direction B in fig. 4. The discomfort of passengers caused by the fact that hot air is discharged towards the passengers on the seats is avoided, and the heat carried by the hot air is obviously reduced in the process that the hot air rises from the bottom to the top in the carriage, so that the discomfort of sensitive parts of the passengers, such as the heads, is reduced.

Fig. 5 is a schematic structural view of a rear footrest according to an embodiment of the present disclosure, and as shown in fig. 5, the rear footrest 10 is generally long-strip-shaped, and the transverse cross section of the rear footrest is generally arched, so that when the rear footrest 10 is covered on the bottom of the rear door frame, the space between the rear footrest 10 and the bottom of the rear door frame is hollow, so as to form a first sub-channel 1. The rear step board 10 further includes a connecting portion 11 at one end thereof, and the connecting portion 11 is connected to an exhaust duct 30 of the power train device. Fig. 6 is a schematic structural view illustrating a connection between a rear foot board and an exhaust duct according to an embodiment of the present disclosure. As shown in fig. 5 and 6, the connecting portion 11 at one end of the rear footrest 10 is connected to the outlet end of the exhaust duct 30 of the power train device.
