[0039] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0040] To facilitate the description of the technical effects of the technical solution of the present application, the vehicle defrosting solution in the prior art is introduced as follows:

[0041] The prior art discloses a sealing joint and a door defrosting assembly for sealing a door and an instrument panel, wherein the sealing joint comprises a fixed section, a deformation section and a sealing section. When the door is in a closed state, the end of the sealing section away from the deformation section is pressed against the instrument panel, and the deformation section is bent and deformed; when the door is in an open state, the end of the sealing section away from the deformation section is spaced from the instrument panel, and the deformation section returns to its original state. The sealing joint of this patent requires multi-color injection molding, which has a low yield and high cost; and there is a risk of cracking at the mold joint between the fixed section, the deformation section and the sealing section after multiple deformations.

[0042] The prior art also discloses a side defrosting ventilation structure installed on a car door panel, in which a rubber sleeve is clamped at the air inlet of the door panel, and the air inlet end face of the defrosting air duct and the end face of the rubber sleeve are fitted to achieve sealing. This patent does not solve the problem of the serious deformation of the rubber sleeve affecting the appearance of the car and the air leakage in the air duct.

[0043] The prior art also discloses an instrument panel left and right end cover assembly with optimized side defrosting function, including instrument panel left and right end cover plates, the instrument panel left and right end cover plates are provided with ventilation holes, the ventilation holes are provided with sealing rings, the outer side of the sealing rings has an outer folding soft rubber, the inner side also has an inner folding soft rubber, and the sealing rings are provided with grilles. The outer side of the sealing rings has an outer folding soft rubber, the inner side also has an inner folding soft rubber, and the soft rubber secondary injection molding process is adopted. The outer side of the soft rubber is matched with a grille to ensure that the left and right end covers match the door panels, the blowing volume ensures the effectiveness of the defrosting and defogging of the whole vehicle, and ensures driving safety. This patent does not solve the problem of serious deformation of the rubber sleeve that affects the appearance of the car and air leakage in the air duct.

[0044] In summary, the existing technologies are unable to solve the problem that the sealing deformation of the connection structure between the door panel and the instrument panel affects the defrosting performance.

[0045] Combination Figures 1 to 5a , Figure 6 to Figure 7 As shown, according to a specific embodiment of the present application, a door panel side defrost air intake system is provided.

[0046] The door panel side defrost air intake system includes a first defrost air duct 1, a first air intake grille assembly 2, a second defrost air duct 4 and a second air intake grille assembly 3. The first end of the first defrost air duct 1 is connected to the air conditioning box; the first air intake grille assembly 2 is arranged at the second end of the first defrost air duct 1, the first air intake grille assembly 2 at least includes a first air intake grille 21, the first air intake grille 21 is connected to the instrument panel guard plate 5, and a first sealing assembly is arranged between the first air intake grille 21 and the instrument panel guard plate 5; the first end of the second defrost air duct 4 is connected to the air conditioning box, and the second end of the second defrost air duct 4 is arranged to communicate with the second end of the first defrost air duct 1; the second air intake grille assembly 3 is arranged at the second end of the second defrost air duct 4, the second air intake grille assembly 3 at least includes a second air intake grille 31, the second air intake grille 31 is connected to the door panel 6, and a second sealing assembly is arranged between the second air intake grille 31 and the door panel 6; wherein, along the air flow direction, the first sealing assembly and the second sealing assembly are arranged to interfere with each other.

[0047] By applying the technical solution of this embodiment, the first sealing assembly and the second sealing assembly are arranged to interfere with each other. When the assembly gap between the vehicle door and the instrument panel deviates from the initial state, the first sealing assembly and the second sealing assembly can maintain contact with each other to ensure the sealing effect. This solves the problem in the prior art that the sealing effect of the defrost duct on the door panel side decreases after the assembly gap between the vehicle door and the instrument panel deviates from the design state due to multiple openings and closings of the vehicle door. This avoids air leakage in the defrost duct and improves the defrost performance.

[0048] Those skilled in the art should understand that, in the embodiments of the application, along the airflow direction, the first sealing assembly and the second sealing assembly are arranged to interfere with each other, which means that the first sealing assembly and the second sealing assembly at least partially overlap along the radial direction of the air duct, and when the assembly gap between the vehicle door and the instrument panel increases or decreases along the airflow direction (that is, the axial direction of the air duct), the projections of the first sealing assembly and the second sealing assembly along the radial direction of the air duct always maintain partial overlap, and at the same time, the first sealing assembly and the second sealing assembly maintain contact sealing, so that the sealing effect of the defrost air intake system on the door panel side is maintained well.

[0049] Figure 5a FIG. 2 shows a schematic structural diagram of a first defrost air duct 1 according to an embodiment of the present application. In the embodiment of the present application, the first defrost air duct 1 is provided with a first air intake grille 21. Figure 5b The structure diagram of the first defrost air duct 1 in the prior art is shown. The first defrost air duct 1 in the prior art is not provided with the first air intake grille 21. When the car door is opened, the user can directly see the first air intake grille assembly 2 on the dashboard side. The first air intake grille 21 can improve the appearance of the car. The second air intake grille 31 arranged in the second defrost air duct 4 also has the function of improving the appearance of the car.

[0050] In an embodiment of the present application, the first defrost duct 1 draws air from the air conditioning box for defrosting the side windshields, and the second defrost duct 4 draws air from the air conditioning box for defrosting the side windshields.

[0051] In an exemplary embodiment of the present application, the first air intake grille assembly 2 is fixedly mounted on the instrument panel guard plate 5 , and the second air intake grille assembly 3 is fixedly mounted on the door panel 6 .

[0052] Specifically, the first sealing assembly includes a first sealing structure 22, and the first sealing structure 22 is disposed between the first air intake grille 21 and the instrument panel guard plate 5. By providing the first sealing structure 22, the connection and sealing between the first air intake grille 21 and the instrument panel guard plate 5 can be ensured.

[0053] Preferably, the first sealing structure 22 and one of the first air intake grille 21 are provided with a first matching protrusion 220, and the first sealing structure 22 and the other of the first air intake grille 21 are provided with a first matching groove 210, and the first sealing structure 22 and the first air intake grille 21 are matched and connected through the first matching protrusion 220 and the first matching groove 210. By providing the first matching protrusion 220 and the first matching groove 210, the assembly strength and relative position accuracy between the first sealing structure 22 and the first air intake grille 21 can be guaranteed.

[0054] like Figure 3 As shown, in an exemplary embodiment of the present application, a plurality of first matching grooves 210 are provided on the first air intake grille 21, and a plurality of first matching protrusions 220 are provided on the first sealing structure 22, and the first matching protrusions 220 are provided in a one-to-one correspondence with the first matching grooves 210. Preferably, the first air intake grille 21 is also provided with a limited step surface, and one end of the first sealing structure 22 abuts against the limited step surface.

[0055] Specifically, the second sealing assembly includes a fixed structure 33 and a second sealing structure 32, one side of the fixed structure 33 is connected to the door panel 6, and the other side of the fixed structure 33 is connected to the second air intake grille 31; at least part of the second sealing structure 32 is arranged between the fixed structure 33 and the second air intake grille 31; wherein, along the airflow direction, the second sealing structure 32 and the first sealing structure 22 are arranged to interfere with each other. By arranging part of the second sealing structure 32 between the fixed structure 33 and the second air intake grille 31, the position of the second sealing structure 32 can be fixed, the displacement of the second sealing structure 32 can be avoided, and the sealing performance of the structure can be improved.

[0056] Furthermore, at least one of the first sealing structure 22 and the second sealing structure 32 is made of elastic material. The elastic material can ensure that the sealing structure has certain deformation and rebound characteristics, ensuring reliable sealing. Preferably, both the first sealing structure 22 and the second sealing structure 32 are made of elastic material to enhance the deformation recovery ability of the door panel side defrosting air intake system, thereby ensuring the subsequent sealing effect.

[0057] Preferably, the hardness of the first sealing structure 22 is set greater than the hardness of the second sealing structure 32 .

[0058] In this embodiment, the second sealing structure 32 with lower hardness has better deformation and rebound characteristics, ensuring that the first sealing structure 22 with higher hardness can meet the defrost duct sealing requirements when the deformation amount is smaller; the coordination scheme of the second sealing structure 32 with different hardness and the first sealing structure 22 can ensure that the sealing structure will not suffer irreversible serious deformation. When the car door is opened, the first sealing structure 22 and the second sealing structure 32 can both be restored to the designed state, thereby meeting the user's car appearance requirements.

[0059] According to actual needs, the hardness of the first sealing structure 22 may also be set to be smaller than the hardness of the second sealing structure 32 .

[0060] Preferably, the second sealing structure 32 is a sponge, which has relatively low hardness and good rebound and deformation properties, and can meet the sealing requirements.

[0061] Preferably, the first sealing structure 22 is made of rubber. Rubber has high hardness and certain deformation and rebound properties, which can improve structural stability and ensure sealing effect.

[0062] Furthermore, along the axial direction of the second air intake grille 31, part of the fixed structure 33 is connected to the second air intake grille 31, and another part of the fixed structure 33 is arranged at a distance from the second air intake grille 31, so that a limiting space 310 is formed between the fixed structure 33 and the second air intake grille 31, and at least part of the second sealing structure 32 is located in the limiting space 310.

[0063] In an embodiment of the present application, part of the second sealing structure 32 is located in the limiting space 310, and another part of the second sealing structure 32 interferes with the first sealing structure 22 along the airflow direction. When the distance between the second air intake grille 31 and the first air intake grille 21 is reduced, the fixed structure 33 and the second air intake grille 31 can limit and fix the second sealing structure 32 to prevent the second sealing structure 32 from shifting. The second sealing structure 32 and the first sealing structure 22 are squeezed and deformed, and always interfere with each other to ensure the sealing of the system.

[0064] Preferably, in an exemplary embodiment of the present application, the second sealing structure 32 is configured as a bending structure, the bending structure includes a first section and a second section which are arranged at an angle, the first section is arranged parallel to the airflow direction, and the first section is located between the fixed structure 33 and the second air intake grille 31, one side of the second section abuts against the fixed structure 33, and the other side of the second section interferes with the first sealing structure 22.

[0065] In an exemplary embodiment of the present application, the initial state of the door panel side defrost intake system is as follows: Figure 6 As shown, the interference amount between the second sealing structure 32 and the first sealing structure 22 can be determined at the beginning of the design, that is, the second sealing structure 32 and the first sealing structure 22 both have certain deformation and rebound characteristics. In the initial state, there is a certain interference amount between the second sealing structure 32 and the first sealing structure 22, and the sealing performance is ensured by the deformation of the two second sealing structures 32 and the first sealing structure 22; after opening and closing the door many times, the assembly gap between the door and the instrument panel deviates from the initial state. If the gap increases, the sealing performance between the second sealing structure 32 and the first sealing structure 22 can be ensured by designing the interference size between the second sealing structure 32 and the first sealing structure 22; Figure 7 The normal deformation state of the second sealing structure 32 and the first sealing structure 22 is shown. If the gap is reduced, since the second sealing structure 32 of the second air intake grille assembly 3 has good deformation and rebound characteristics and low hardness, the second sealing structure 32 on the door panel side can undergo a larger deformation, ensuring that the first sealing structure 22 on the instrument panel side undergoes a smaller deformation to meet the sealing requirements.

[0066] Figure 8 The figure shows the serious deformation state of the air duct sealing structure in the prior art. In the prior art, high-hardness materials such as plastic are often used to make the sealing structure. When the assembly gap between the door and the dashboard is reduced, the sealing structure of the dashboard side air intake grille assembly will be seriously deformed, resulting in air leakage in the defrosting air duct, affecting the defrosting performance and thus driving safety; serious deformation of the sealing structure will also affect the appearance of the car and cause user complaints. Compared with the technical solution of using high-hardness materials such as plastic to make the sealing structure in the prior art, the sealing structure in this embodiment can restore the second sealing structure 32 and the first sealing structure 22 to their initial state when the door is opened, thereby meeting the appearance requirements of the sealing structure.

[0067] Preferably, one of the second sealing structure 32 and the fixed structure 33 is provided with a second matching protrusion 330, and the other of the second sealing structure 32 and the fixed structure 33 is provided with a second matching groove 320, and the second sealing structure 32 and the fixed structure 33 are matched and connected through the second matching protrusion 330 and the second matching groove 320. By providing the second matching protrusion 330 and the second matching groove 320, the assembly strength and relative position accuracy between the second sealing structure 32 and the fixed structure 33 can be guaranteed.

[0068] like Figure 4 As shown, in an exemplary embodiment of the present application, a plurality of second mating protrusions 330 are provided on the fixing structure 33 , a plurality of second mating grooves 320 are provided on the second sealing structure 32 , and the second mating protrusions 330 and the second mating grooves 320 are provided in a one-to-one correspondence.

[0069] Furthermore, the door panel side defrosting air intake system also includes a third sealing assembly 7, which is arranged between the first air intake grille assembly 2 and the first defrosting air duct 1. The third sealing assembly 7 can ensure the sealing of the first air intake grille assembly 2 and the first defrosting air duct 1, and avoid air leakage in the air duct, which affects the defrosting performance.

[0070] Furthermore, the door panel side defrosting air intake system also includes a fourth sealing assembly 8, which is arranged between the second air intake grille assembly 3 and the second defrosting air duct 4. The fourth sealing assembly 8 can ensure the sealing of the second air intake grille assembly 3 and the second defrosting air duct 4, and avoid air leakage in the air duct, which affects the defrosting performance.

[0071] In an exemplary embodiment of the present application, the third sealing assembly 7 and the fourth sealing assembly 8 are both foam structures.

[0072] According to another specific embodiment of the present application, a vehicle is provided, the vehicle having a door panel side defrost air intake system, and the door panel side defrost air intake system is the door panel side defrost air intake system in the above embodiment.
