[0002] When there's a significant temperature difference between a vehicle's interior and exterior, moisture or frost often forms on the windshield. This is especially true in cold regions or during winter. This can severely impair the driver's vision and easily lead to traffic accidents. Therefore, a defrost and defogging system is typically installed between the dashboard and the windshield to remove moisture or frost from the windshield.

[0003] Currently, the air ducts in the front defrost and defogging systems on long-nose heavy-duty truck dashboards are mostly concentrated in the middle. However, the curvature of the windshield on these trucks is generally large, extending far to the sides. This prevents the air ducts from fully covering the windshield, resulting in poor defrosting and defogging uniformity. Furthermore, the large angle between the air ducts and the windshield makes it difficult for the air to climb along the windshield and reach the top, reducing both the uniformity and efficiency of defrosting and defogging.

[0004] Therefore, it is urgent to propose a front defrost and defogger air duct structure and a long-head heavy truck to solve the above technical problems. Utility Model Content

[0035] This embodiment provides a front defrost and defogger air duct structure, the air outlet of which is fitted with the front windshield, with better air outlet uniformity, thereby improving the comprehensiveness of defrost and defogger, and optimizing the air outlet angle to improve the efficiency of defrost and defogger.

[0036] Specifically, if Figure 1-Figure 3As shown, the front defrost and defogging air duct structure includes an instrument panel body 100 and a panel 200. The instrument panel body 100 is disposed inside the front windshield 10. The panel 200 is disposed between the instrument panel body 100 and the front windshield 10. The panel 200 and the instrument panel body 100 enclose an air duct 300. The air duct 300 has an air inlet 310 connected to the air conditioning unit 20 and a plurality of air outlets 320 that blow toward the front windshield 10. The plurality of air outlets 320 are spaced apart along the extension direction of the instrument panel body 100 so that air blown out of the plurality of air outlets 320 can cover the front windshield 10 along the extension direction of the instrument panel body 100. Specifically, the plurality of air outlets 320 are arranged to fit the front windshield 10, so that air outlets 320 are distributed uniformly in the center and on both sides of the front windshield 10. This ensures that the airflow from the air outlets 320 fully covers the front windshield 10, thereby improving the uniformity of defrosting and defogging. At the same time, the air duct 300 is formed by the enclosure 200 and the instrument panel body 100 , which has a simple structure, occupies a small space, and can be applied to a smaller installation space.

[0037] Furthermore, the angle a between the airflow from the air outlet 320 and the front windshield 10 is 31°-33°. This angle allows the air from the air outlet 320 to adhere well to the front windshield 10 and climb to the top of the front windshield 10, resulting in a larger proportion of air effectively defrosting and defogging, thereby improving the defrosting and defogging efficiency.

[0038] It is worth noting that the extension direction of the instrument panel body 100 is Figure 2 In the direction indicated by the arrow.

[0039] Further, see Figure 2 The line connecting the multiple air outlets 320 is an arc, and the curvature of the arc on which the multiple air outlets 320 are located is the same as the curvature of the front windshield 10. This arrangement allows the multiple air outlets 320 to better fit the curvature of the front windshield 10, further improving the uniformity of defrosting and defogging of the front defrost and defogging duct structure, and reducing the driving risks caused by incomplete defrosting or defogging of the front windshield 10.

[0040] Optionally, in this embodiment, the curvature of the arc where the plurality of air outlets 320 are located is less than or equal to 5m -1 .

[0041] Optionally, continue with Figure 2In one possible embodiment, five air outlets 320 are provided. The five air outlets 320 are evenly spaced along the extension direction of the instrument panel body 100. Each air outlet 320 is fan-shaped, and the distance between two adjacent air outlets 320 is 2 cm to 5 cm. For example, the distance between two adjacent air outlets 320 can be 2 cm, 3 cm, 4 cm, or 5 cm, etc., and can be set according to actual needs and is not specifically limited in this application.

[0042] Furthermore, a plurality of grilles are provided in each air outlet 320, and the plurality of grilles are arranged at intervals. By providing a plurality of grilles in the air outlet 320, it is possible to effectively prevent foreign matter from entering the air duct 300 through the air outlet 320 and causing damage to the vehicle.

[0043] Optionally, the multiple grilles in each air outlet 320 can be arranged at equal intervals or at variable intervals, depending on actual needs, and this application does not make any specific limitations.

[0044] Optionally, the maximum width of the air outlet 320 is less than or equal to 1.05 times the minimum width of the air outlet 320. This configuration can avoid vortexes caused by sudden changes in the width of the air outlet, effectively reduce the pressure inside the air duct 300, and improve the flow efficiency of the air in the air duct 300.

[0045] Further, see Figure 2 A first air deflector 110 and a second air deflector 211 are respectively provided on the side of the enclosure 200 near the air outlet 320 and the side of the instrument panel body 100 near the air outlet 320. The first air deflector 110 and the second air deflector 211 are used to guide the wind. The provision of the first air deflector 110 and the second air deflector 211 ensures that the wind discharged from the air outlet 320 is directed toward the front windshield 10 in a predetermined direction, thereby improving the reliability of the front defrost and defogging air duct structure.

[0046] Optionally, in this embodiment, the first wind deflector 110 and the second wind deflector 211 both extend in the vertical direction to guide the wind to blow toward the front windshield 10 in the vertical direction.

[0047] Optionally, in one embodiment, the side wall of the instrument panel body 100 near the front windshield 10 is a first air deflector 110. With this configuration, the first air deflector 110 not only shapes the instrument panel body 100 but also guides the air, simplifying the structure of the front defrost and defogging duct 300.

[0048] Optionally, in a possible embodiment, the second air guide plate 211 and the enclosure plate 200 are an integrated structure. This arrangement facilitates processing and assembly.

[0049] Further, see Figure 1 and Figure 2 The enclosure 200 includes an upper enclosure 210 and a lower enclosure 220, wherein the upper enclosure 210 and the lower enclosure 220 are detachably connected, and the upper enclosure 210 is arranged close to the front windshield 10. By separating the enclosure 200, the installation of the enclosure 200 in a small space is facilitated.

[0050] Optionally, in one possible embodiment, the upper panel 210 and the lower panel 220 are connected by bolts. This bolt connection has a simple structure, is easy to install and remove, and has high connection strength. In another possible embodiment, the upper panel 210 and the lower panel 220 can also be connected by a clip connection. This clip connection has a simple structure, is easy to install and remove, and helps improve installation and maintenance efficiency. Of course, in other embodiments, the connection between the upper panel 210 and the lower panel 220 can also be other methods, which can be configured according to actual needs and are not specifically limited in this application.

[0051] This embodiment also provides a long-nose heavy truck, comprising a vehicle body, a front windshield 10 and the above-mentioned front defrost and defogger air duct structure. The front windshield 10 is arranged on the vehicle body, and the front defrost and defogger air duct structure is arranged on the inner side of the front windshield 10.

[0052] The long-nose heavy truck has higher driving safety due to the adoption of the above-mentioned front defrost and demisting air duct structure.
