[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] Embodiment 1

[0041] This embodiment relates to a front defrost duct assembly of an instrument panel, which can improve the defrosting effect of the front windshield 5; an exemplary structure thereof is as follows Figure 1 , Figure 2 , Figure 3 and Figure 4 shown.

[0042] In general, the instrument panel front defrost duct assembly includes an instrument panel upper frame 1, and a front defrost duct 2 buckled at the bottom of the instrument panel upper frame 1, and a main duct 20 is formed between the instrument panel upper frame 1 and the front defrost duct 2. A central air outlet 10 is provided in the middle of the instrument panel upper frame 1, and a front air outlet 12 facing the root of the front windshield 5 is formed by the gap between the instrument panel upper frame 1 and the front end of the front defrost duct 2. The airflow entering the main air duct 20 from the air inlet 220 of the front defrost duct 2 is blown toward the front windshield 5 through the central air outlet 10 and the front air outlet 12 respectively.

[0043] It should be pointed out that, based on the above-mentioned overall design concept, the technical solution of the utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the front defrost duct 2 and the upper frame 1 of the instrument panel can be fixedly connected in the form of snap connection, screw connection, etc., or can be fixedly connected in the form of welding. For the parts required for the implementation of the overall solution but not involved in the above-mentioned overall setting, reasonable and flexible designs can be made with reference to the mature setting means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only a better one of the many schemes that can be formed by the above-mentioned various combinations and changes. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many schemes that can be formed by the above-mentioned combinations and changes of various specific forms, as well as the specific implementation scheme of this embodiment, are all within the scope of protection of the utility model.

[0044] like Figure 4 , Figure 5 Combined with Figure 1 As shown, in this embodiment, the central air outlet 10 is constructed as a long strip arranged along the width direction of the vehicle, and the first angle α between the airflow blown out of the central air outlet 10 and the front windshield 5 is set between 35°-45°. The central air outlet 10 is arranged in a long strip along the width direction of the vehicle, so that a long strip of wind can be blown out from the central air outlet 10, increasing the blowing area on the surface of the front windshield 5, which is conducive to improving the blowing and heating effect of the central air outlet 10. At the same time, the wind direction of the air outlet of the central air outlet 10 and the angle between the front windshield 5 are set within a reasonable angle range. After the air blown out from the central air outlet 10 contacts the front windshield 5, it will flow upward along the front windshield 5, thereby greatly improving the defrosting effect on the front windshield 5. The specific angle can be reasonably adjusted within the set range. For example, the first angle α can be set to 35°, 40°, 43.5° or 45°, etc. When it is set to 43.5°, based on the front windshield 5 generally tilted backward at 45°, the air from the central air outlet 10 is basically blown straight upwards.

[0045] Moreover, a panel 3 is provided at the top of the upper frame 1 of the instrument panel of the present embodiment, and a grille window 30 is provided on the panel 3 corresponding to the central air outlet 10. The panel 3 is provided at the top of the upper frame 1 of the instrument panel to improve the aesthetics of the surface of the upper frame 1 of the instrument panel; the grille window 30 is provided on the panel 3 corresponding to the central air outlet 10, and by setting a reasonable inclination posture of the grille blades, a good flow guiding effect can be played on the air outlet of the central air outlet 10, and while ensuring the aesthetics of the outer surface of the panel 3, the defrosting effect of the air outlet of the central air outlet 10 on the front windshield 5 can be improved.

[0046] Based on the arrangement of the panel 3, a diverter plate 31 is arranged on the side of the panel 3 facing the upper frame 1 of the instrument panel, and the diverter plate 31 is located on the side of the grille window 30 close to the front air outlet 12; and the diverter plate 31 extends downward into the main air duct 20, and the airflow in the main air duct 20 is diverted by the diverter plate 31 to be blown out through the central air outlet 10 and the front air outlet 12 respectively. By arranging the diverter plate 31 on the panel 3, the diverter plate 31 can play a good diverting role on the airflow in the main air duct 20, and by setting the extension length of the diverter plate 31 within a reasonable range, the airflow in the main air duct 20 can be reasonably blown out from the central air outlet 10 and the front air outlet 12 respectively at a reasonable flow rate, so as to improve the comprehensive defrosting effect of the upper frame 1 of the instrument panel.

[0047] The air outlet direction of the front air outlet 12 can also be flexibly set within a reasonable range. Figure 4 As shown, the second angle β between the airflow blown out from the front air outlet 12 and the front windshield 5 is set between 90°-100°; at the same time, a sealing strip 4 is provided between the front defrost air duct 2 and the front windshield 5 on the side below the front air outlet 12. The second angle β between the air outlet direction of the front air outlet 12 and the front windshield 5 is set between 90°-100°, and the air outlet of the front air outlet 12 is basically perpendicular to the front windshield 5 and blows toward the root of the front windshield 5. Since the sealing strip 4 is provided between the front defrost air duct 2 and the front windshield 5, the airflow will turn upward, flow along the surface of the front windshield 5, and flow upward through the front defrost air duct 13 between the front windshield 5 and the upper frame 1 of the instrument panel, which can ensure the overall defrosting effect of the airflow on the front windshield 5.

[0048] At the same time, it should be pointed out that in addition to the sealing strip 4 provided between the front defrost duct 2 and the front windshield 5, a sealing strip 4 should also be provided between the portion where the front defrost duct 2 and the upper frame 1 of the instrument panel are engaged. Sealing ribs 40 or sealing strips 4 and other structures may also be provided at the mating portion between the grille window 30 of the panel 3 and the central air outlet 10 of the upper frame 1 of the instrument panel. By providing each sealing strip 4 and sealing rib 40, the sealing effect of the connection portions of the components can be improved to prevent airflow leakage in the front defrost duct assembly of the instrument panel.

[0049] In addition, the gap or width of the central air outlet 10, the air outlet gap b of the front air outlet 12, and the front defrost air duct 13 between the upper frame 1 of the instrument panel and the front windshield 5 can be appropriately adjusted within a reasonable range. Figure 4 , Figure 5 As shown, in this embodiment, the air outlet width a of the central air outlet 10 is between 12mm-20mm. The air outlet gap b of the front air outlet 12 is between 3mm-5mm. In addition, a front defrost duct 13 is formed by setting a gap between the upper frame 1 of the instrument panel and the front windshield 5 on one side above the front air outlet 12, and the air duct width c of the front defrost duct 13 is between 5mm-7mm. By setting the above reasonable range, not only can sufficient defrost air volume be guaranteed, but also the air flow velocity can be controlled within a reasonable range, which ensures the rationality of the overall structure of the defrost duct assembly in front of the instrument panel and its good defrost effect.

[0050] In addition, in the present embodiment, in the front-to-back direction of the vehicle, the spacing d between the front air outlet 12 and the central air outlet 10 is 80 mm-115 mm; in the up-down direction of the vehicle, the height difference h between the front air outlet 12 and the upper edge of the black glass border 50 at the bottom of the front windshield 5 is 12 mm-20 mm.

[0051] In the longitudinal direction of the front and rear of the vehicle, the distance between the central air outlet 10 and the front air outlet 12 is set within a reasonable range. At the position where the flow intensity of the air outlet of the front air outlet 12 is weakened, the air outlet of the central air outlet 10 can just blow onto the front windshield 5, thereby further improving the coordination effect of the central air outlet 10 and the front air outlet 12, which is helpful to improve the overall defrosting effect of the front windshield 5. Based on the fact that the front air outlet 12 is located below the black border 50 of the glass at the bottom of the front windshield 5, a reasonable height difference h is set between the upper edge of the black border 50 of the glass and the front air outlet 12, which can ensure that the front air outlet 12 cannot be seen from outside the vehicle, and the appearance effect is better. It should be pointed out here that the width dimensions of each air outlet, the spacing dimensions between different air outlets, the height difference between the black border 50 of the glass and the front air outlet 12, etc. can be adjusted separately, and there is no mutual restriction relationship between the various features.

[0052] In addition, in this embodiment, the front defrost duct 2 is assembled by the duct body 21 and the duct guide plate 22, the main duct 20 and each air outlet are mainly formed on the duct body 21, the duct guide plate 22 is buckled in the middle of the rear side of the duct body 21, and the air inlet 220 is formed between the duct body 21 and the bottom of the duct guide plate 22, and is connected to the air outlet duct of the air conditioning system. The setting of the duct guide plate 22 facilitates the processing structure of the front defrost duct 2 and the flexible setting of the air inlet 220. At the same time, a layer of sound-absorbing cotton 221 can be covered on the outside of the duct guide plate 22 to improve the heat insulation and noise reduction effect of the front defrost duct assembly of the instrument panel.

[0053] like Figure 6 as well as Figure 3 As shown, a plurality of front enclosure plug-in parts 212 are provided at the bottom of the air duct main body 21 of the present embodiment, and these front enclosure plug-in parts 212 can realize the plug-in fixed connection between the front defrost air duct 2 and the front enclosure sheet metal 6 of the vehicle, thereby improving the overall installation structural stability of the instrument panel front defrost air duct assembly.

[0054] In addition, if Figure 1 , Figure 2 As shown, the front end edge portion of the front defrost duct 2 of the present embodiment is provided with a plurality of upwardly convex connecting bosses 210 at intervals, and a front end air outlet duct 200 connecting the main duct 20 and the front end air outlet 12 is formed between adjacent connecting bosses 210; welding ribs 211 are constructed on the rear edge of the front defrost duct 2 and the connecting bosses 210, and the front defrost duct 2 is welded to the upper frame 1 of the instrument panel through the welding ribs 211.

[0055] By setting a plurality of connecting bosses 210 at the front edge of the front defrost duct 2, after the connecting bosses 210 abut against the upper frame 1 of the instrument panel, the height of the connecting bosses 210 determines the gap size between the front defrost duct 2 and the upper frame 1 of the instrument panel (i.e., the air outlet gap b of the front air outlet 12), and at the same time, a front air outlet duct 200 can be formed between adjacent connecting bosses 210, thereby achieving a good ventilation effect of the front air outlet 12. Welding ribs 211 are set on the rear edge of the front defrost duct 2 and each connecting boss 210 at the front edge of the front defrost duct 2, and the top of the welding ribs 211 can adopt a triangular structure to facilitate the welding and fixing between the front defrost duct 2 and the upper frame 1 of the instrument panel, so that the front defrost duct 2 and the upper frame 1 of the instrument panel form a solid whole.

[0056] In addition to the central air outlet 10 and the front air outlet 12, the main air duct 20 of this embodiment is extended in the left and right directions of the vehicle, and the left and right ends of the front defrost air duct 2 are respectively formed with side air outlet ducts 201 with openings facing upwards; corresponding to the openings of the side air outlet ducts 201, side air outlets 11 are opened on the upper frame 1 of the instrument panel. Figure 1 and Figure 7 As shown, by respectively arranging side air outlet ducts 201 at the left and right end portions of the main air duct 20, the side air outlet duct 201 can blow the air flow into the side defrost duct 7 formed between the A-pillar upper trim 8 and the side panel through the side air outlet 11 on the upper frame 1 of the instrument panel, and the air is blown onto the window glass of the front door through the guidance of the side defrost grille 70 in the side defrost duct 7, thereby achieving the effect of defrosting and defogging.

[0057] Based on the above overall configuration, the front defrost duct assembly of the instrument panel of this embodiment is configured to discharge air, such as Figure 1 , Figure 4 and Figure 5 In the direction indicated by the arrow in the figure, the airflow will enter the main air duct 20 from the air inlet 220, and the first part of the airflow will be blown out from the central air outlet 10; the second part of the airflow will flow along the main air duct 20 to the left and right sides, and will be blown out from the front air outlet 12 through the front air outlet duct 200; the third part of the airflow will flow along the main air duct 20 to the left and right ends of the front defrost air duct 2, turn upward at the side air outlet duct 201, and be blown out from the side air outlet 11. The first and second parts of the airflow can have a good defrosting and defogging effect on the front windshield 5, and the third part of the airflow can have a defrosting and defogging effect on the car door windows.

[0058] To summarize, the front defrost duct assembly of the instrument panel in the present embodiment is configured by setting a front defrost duct 2 below the upper frame 1 of the instrument panel, and adopting a snap-fitting method to form a hollow main duct 20 between the two; a central air outlet 10 is opened in the middle of the upper frame 1 of the instrument panel, and a front air outlet 12 is set in the gap between the upper frame 1 of the instrument panel and the front edge of the front defrost duct 2. The front air outlet 12 will blow hot air to the bottom of the windshield 5, and the central air outlet 10 can blow hot air to the middle and lower part of the windshield 5. The two air outlets cooperate with each other to enhance the overall heating effect of the windshield 5, thereby helping to improve the defrosting effect of the windshield 5.

[0059] Embodiment 2

[0060] The present embodiment relates to a vehicle, on which the dashboard front defrost duct assembly provided in the first embodiment is provided.

[0061] Through the description of the first embodiment, it can be seen that the instrument panel front defrost duct assembly of the utility model has a small number of overall components, among which the duct body 21 is integrally formed, has a simple structure, and is integrally welded with the instrument panel upper frame 1, thereby improving the overall strength of the instrument panel. The top of the welding rib 211 on the duct body 21 is triangular, which is easier to weld. At the same time, the use of multiple welding ribs 211 ensures the connection firmness and sealing effect between the front defrost duct 2 and the instrument panel upper frame 1.

[0062] In addition, the front air outlet 12 can blow out a narrow rapid airflow toward the root of the front windshield 5, which can improve the overall defrosting effect of the front windshield 5; the air duct guide plate 22 can well guide the air blown out by the air conditioner into the main air duct 20, and then the airflow in the main air duct 20 is split into two by the splitter plate 31 on the panel 3, one of which is blown vertically upward from the central air outlet 10 to the front windshield 5, and the other is blown toward the root of the front windshield 5 through the front air outlet 12. The two airflows directed to the front windshield 5 cooperate with each other, which well improves the defrosting and defogging effect on the front windshield 5.

[0063] The above is only a preferred embodiment of the present invention. The detailed explanation of the configuration, the examples of the specific structural setting, or the description of the assembly connection method, etc., are all for the purpose of full disclosure so that those skilled in the art can better implement the present invention, and are not intended to limit the scope of protection of the present invention.
