Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0031] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0032] like Figures 1-2 As shown, the defrosting system provided in this application embodiment includes a central defrosting duct 100, which connects to the windshield of the air conditioning unit, allowing the air conditioning unit to send air along the central defrosting duct to the windshield for defrosting. A main airflow deflector 130 is disposed inside the central defrosting duct 100. The main airflow deflector 130 is an eccentric structure biased towards the driver's seat. Under the guidance of the main airflow deflector 130, more air from the air conditioning unit is directed towards the driver's seat, improving the driver's forward visibility. The defrosting effect in the field area; the central defrost duct 100 is detachably and fixedly connected to the left defrost duct 200, which connects to the central defrost duct 100 and the left side window glass, so that the air conditioning unit can supply air to the left field of vision along the left defrost duct 200; the central defrost duct 100 is detachably and fixedly connected to the right defrost duct 300, which connects to the central defrost duct 100 and the right side window glass, so that the air conditioning unit can supply air to the right field of vision along the right defrost duct 300. Thus, if... Figure 5As shown, the air from the air conditioning unit can be delivered to the front, left, and right visual areas respectively via the central defrost duct 100, left defrost duct 200, and right defrost duct 300. The airflow is further directed towards the driver's seat via the main airflow deflector 130, which increases the defrost area in the driver's field of vision during driving, improves the defrost effect of the defrost system, and enhances driving safety.

[0033] like Figure 1 As shown, the central defrost duct 100 includes a central duct body 101, which is provided with an air inlet 110 and a central air outlet grille 120. The air inlet 110 is used to connect to the air conditioning unit, and the central air outlet grille 120 is used to connect to the instrument panel 400, so that the air provided by the air conditioning unit can enter the central duct body 101 from the air inlet 110 and be sent to the windshield from the central air outlet grille 120. Under the guidance of the main airflow deflector 130, more air can be sent to the driver's seat.

[0034] The main airflow deflector 130 is fixedly connected inside the central duct body 101, and extends from the air inlet 110 to the central air outlet grille 120, so that the air from the air conditioning unit can be guided by the main airflow deflector 130 to ensure that more air can be delivered to the driver's seat, thereby improving the defrosting effect in the driver's seat visibility area and improving safety. At the same time, by setting the main airflow deflector 130, the main airflow deflector 130 forms a reinforcing rib effect inside the central duct body 101, which improves the strength of the central duct body 101, improves the stability of the air delivery process, and further improves the defrosting effect.

[0035] like Figure 1 As shown, a flow divider 140 is also provided inside the central duct body 101. The flow divider 140 is distributed near the central air outlet grille 120. There are at least two flow dividers 140, and the at least two flow dividers 140 are distributed sequentially along the length of the central air outlet grille 120. This allows the air to be further divided by the flow dividers 140 before it exits near the central air outlet grille 120 after being diverted along the main flow divider 130. This improves the uniformity of the airflow through the central air outlet grille 120, further increases the defrosting area, and improves the defrosting effect.

[0036] For example, such as Figure 1 As shown, there are four air deflectors 140, which are distributed at equal intervals along the length of the central air outlet grille 120 to further improve the uniformity of air supply.

[0037] In other embodiments, the number of deflector plates 140 may be five, six, etc., and this application does not limit this.

[0038] To improve the guiding effect of the diffuser 140, such as Figure 1 As shown, the air distribution plate 140 has an elliptical cylindrical structure, and the major axis of the elliptical cylinder extends from the air inlet 110 to the central air outlet grille 120, which improves the guiding effect of the air distribution plate 140 and further improves the uniformity of air supply.

[0039] In order to connect the central duct body 101 to the instrument panel 400, the central air vent grille 120 is detachably fixed to the instrument panel 400 via connectors 170, and there are at least two connectors 170, which are distributed sequentially along the length of the central air vent grille 120 to ensure the stability of the connection between the central duct body 101 and the instrument panel 400.

[0040] For example, such as Figure 1 As shown, there are six connectors 170, all of which are connected to the instrument panel 400, further improving the stability of the connection.

[0041] In some embodiments, in order to connect the connector 170 and the instrument panel 400, a main locating pin is provided on the instrument panel 400. The connector 170 is positioned and engaged with the main locating pin, and the instrument panel 400 and the connector 170 are connected in sequence by threaded fasteners. There are at least two main locating pins, and each main locating pin corresponds to a connector 170 to achieve the connection between each connector 170 and the instrument panel 400.

[0042] like Figure 1 As shown, the central defrosting duct 100 also includes a first branch pipe 150 and a second branch pipe 160 that are interconnected with the central duct body 101.

[0043] The air inlet of the left defrosting duct 200 is connected to the first branch pipe 150 by the first buckle 210, so that the left defrosting duct 200 and the first branch pipe 150 are connected, so that the air of the air conditioning unit can enter from the air inlet 110 and be diverted along the first branch pipe 150 and defrosted along the left defrosting duct 200 to the left field of view.

[0044] The air inlet of the right defrost duct 300 is connected to the second branch pipe 160 via the second clip 310, so that the right defrost duct 300 and the second branch pipe 160 are connected, so that the air from the air conditioning unit can enter from the air inlet 110 and be split along the second branch pipe 160 and defrost along the right defrost duct 300 to the right field of view.

[0045] like Figures 1-2As shown, the air outlet of the left defrost duct 200 is sealed with a left air outlet grille 220, and the left air outlet grille 220 is detachably fixedly connected to the instrument panel 400. Specifically, the instrument panel 400 is provided with a left positioning pin, the left defrost duct 200 is positioned and engaged with the left positioning pin through a left connector, and the instrument panel 400 is connected to the left connector through threaded fasteners to achieve a detachable fixed connection between the left air outlet grille 220 and the instrument panel 400.

[0046] The right defrost duct 300 has a right air outlet grille 320 sealed and inserted at its air outlet, and the right air outlet grille 320 is detachably and fixedly connected to the instrument panel 400. Specifically, the instrument panel 400 is provided with a right positioning pin, and the right defrost duct 300 is positioned and engaged with the right positioning pin through a right connector, and the instrument panel 400 is connected to the right connector through threaded fasteners to achieve a detachable and fixed connection between the right air outlet grille 320 and the instrument panel 400.

[0047] During the operation of the defrosting system provided in this application embodiment, the air from the air conditioning unit enters the central defrosting duct 100 through the air inlet 110, and is delivered to the front, left, and right visual areas respectively along the central duct body 101, the left defrosting duct 200, and the right defrosting duct 300. The air is then directed to the driver's seat by the main airflow deflector 130 and further guided by the deflector 140, thereby improving the uniformity of air delivery, enhancing the defrosting effect, and improving driving safety.

[0048] like Figures 3-4 As shown in Table 1, the defrosting system provided in this application embodiment increases the defrosting area, improves the accuracy of the defrosting location, and enhances the defrosting effect in the driver's seat's field of vision area compared to the prior art. The defrosting effect comparison shows that the defrosting system provided in this application embodiment increases the defrosting area in the driver's seat A area, passenger seat A1 area, windshield B area, left field of vision area, and right field of vision area by 20.70%, 13.10%, 11.80%, 90.10%, and 63.30%, respectively. Therefore, the defrosting system provided in this application embodiment improves the defrosting effect.
