[0038] This embodiment provides a front panel structure. Figures 1 to 5 As shown, the dash panel structure includes a dash panel body 1, a first air guide 2, and a second air guide 3. The dash panel body 1 is provided with a first air intake grille 11 and a second air intake grille 12. An air conditioning housing 4 is located inside the dash panel body 1. The first air guide 2 is positioned between the first air intake grille 11 and the air conditioning housing 4. The first air guide 2 is used to direct air passing through the first air intake grille 11 to the air intake end of the air conditioning housing 4. A radiator 5 is located inside the dash panel body 1. The second air guide 3 is positioned between the second air intake grille 12 and the radiator 5. The second air guide 3 is used to direct air passing through the second air intake grille 12 to the air intake end of the radiator 5. Specifically, the first air intake grille 11 corresponds to the air conditioning housing 4, and the second air intake grille 12 corresponds to the radiator 5. This correspondence is a feature-based correspondence, not an absolute positional correspondence.

[0039] In this embodiment, the interior of the dash panel body 1 is equipped with an air conditioning housing 4 and a radiator 5. A first air intake grille 11 and a second air intake grille 12 are provided on the dash panel body 1. The first air intake grille 11 corresponds to the air conditioning housing 4, while the second air intake grille 12 corresponds to the radiator 5. A first air guide 2 is provided between the first air intake grille 11 and the air conditioning housing 4. This guide guide 2 directs air passing through the first air intake grille 11 to the air inlet of the air conditioning housing 4, ensuring reliable air supply to the air conditioning housing 4 and thus achieving reliable cooling and heating effects. A second air guide 3 is provided between the second air intake grille 12 and the radiator 5. This guide guide 3 directs air passing through the second air intake grille 12 to the air inlet of the radiator 5, ensuring reliable air supply to the radiator 5, effectively ensuring the operating efficiency of the radiator 5 and improving the fuel economy of the vehicle.

[0040] Specifically, the plurality of grille plates in the first air intake grille 11 have an inclination, and the air is guided by the grille plates when passing through the grille plates, so that the air can flow to the air conditioning box 4 .

[0041] In this embodiment, the first air guide 2 includes a first air guide plate 21 and first air guide fins 22. The first air guide plate 21 is connected between the first air intake grille 11 and the air conditioning housing 4. A first air guide channel 201 is formed between the front panel body 1, the first air guide plate 21, and the air conditioning housing 4. The first air guide fins 22 are disposed within the first air guide channel 201. Air enters the first air guide channel 201 through the first air intake grille 11 and is then guided to the air inlet of the air conditioning housing 4 by the first air guide fins 22. Specifically, outside air passes through the first air intake grille 11 and enters the first air guide channel 201. The air is then guided by the first air guide fins 22 to the air inlet of the air conditioning housing 4, thereby further ensuring reliable air supply to the air conditioning housing 4 and achieving reliable cooling and heating effects.

[0042] Specifically, two first deflectors 21 are spaced apart on either side of the first air intake grille 11. The first ends of the first deflectors 21 are fixed to the inner side of the dash panel body 1, along the side where the air conditioning housing 4 is located. The second ends of the two first deflectors 21 are tilted toward each other. This arrangement allows air that passes through the first air intake grille 11 and enters the first guide channel 201 to flow along the walls of the first deflectors 21, ultimately flowing into the air inlet end of the air conditioning housing 4.

[0043] Specifically, an air inlet 202 is formed between the second ends of the two first air guide plates 21. The air inlet 202 communicates with the air inlet end of the air conditioning housing 4. The fixed ends of the first air guide fins 22 are fixed to the inner side of the front panel body 1, and the air guide ends of the first air guide fins 22 extend obliquely toward the direction of the air inlet 202. Specifically, air passes through the first air intake grille 11 and enters the first air guide channel 201. The air is guided along the walls of the first air guide fins 22 and, under the guidance of the first air guide fins 22, flows toward the air inlet end of the air conditioning housing 4, ultimately entering the air inlet end of the air conditioning housing 4 through the air inlet 202.

[0044] In this embodiment, a first connecting portion 211 extends from the second end of the first air guide plate 21, and a first sealing strip 23 is connected between the first connecting portion 211 and the air conditioning housing 4. Specifically, the first connecting portion 211 is overlapped with the end of the air conditioning housing 4 via the first sealing strip 23. The provision of the first sealing strip 23 can seal the gap between the first connecting portion 211 and the air conditioning housing 4, effectively ensuring the sealing of the first air guide channel 201 and preventing air in the first air guide channel 201 from leaking through the gap between the first connecting portion 211 and the air conditioning housing 4.

[0045] In this embodiment, a filter element (not shown) is provided on the first guide fin 22. The filter element is used to filter impurities from the air within the first guide channel 201. Specifically, the filter element can be an air filter. An air filter is a device that captures dust from a gas-solid two-phase flow through a porous filter material and purifies the gas. The filter element purifies the low-dust air to ensure the cleanliness of the air within the first guide channel 201.

[0046] In this embodiment, the second air guide member 3 includes a second air guide plate 31, which is connected between the second air intake grille 12 and the radiator 5. A second air guide channel 301 is formed between the front panel body 1, the second air guide plate 31 and the radiator 5. Air enters the second air guide channel 301 through the second air intake grille 12 and is guided to the air inlet end of the radiator 5 through the second air guide channel 301.

[0047] Specifically, the outside air passes through the second air intake grille 12 into the second guide channel 301, and then flows to the air inlet end of the radiator 5 under the guiding action of the second guide plate 31, thereby further ensuring reliable air supply to the radiator 5, thereby effectively ensuring the working efficiency of the radiator 5 and improving the fuel economy of the entire vehicle.

[0048] Specifically, two second deflectors 31 are spaced apart on either side of the second air intake grille 12. The first ends of the second deflectors 31 are fixed to the inner side of the dash panel body 1, and the second ends of the two second deflectors 31 are tilted toward each other along the side where the radiator 5 is located. This arrangement allows air that passes through the second air intake grille 12 and enters the second guide channel 301 to flow along the walls of the second deflectors 31, ultimately reaching the air inlet of the radiator 5.

[0049] Optionally, the second air guide 3 further includes second guide fins (not shown) disposed within the second air guide channel 301. Air enters the second air guide channel 301 through the second air intake grille 12 and is guided by the second guide fins to the air inlet of the radiator 5. Specifically, the air within the first air guide channel 201 flows to the air inlet of the radiator 5 under the guidance of the second guide fins, thereby further ensuring reliable air supply to the radiator 5, effectively improving the operating efficiency of the radiator 5, and enhancing the fuel economy of the vehicle.

[0050] In this embodiment, a second connecting portion 311 extends from the second end of the second deflector 31. A second sealing strip 32 is connected between the second connecting portion 311 and the radiator 5. Specifically, the second connecting portion 311 is overlapped with the end of the radiator 5 via the second sealing strip 32. The provision of the second sealing strip 32 can seal the gap between the second connecting portion 311 and the radiator 5, effectively ensuring the sealing of the second guide channel 301 and preventing air in the second guide channel 301 from leaking through the gap between the second connecting portion 311 and the radiator 5.

[0051] Optionally, the material of the first sealing strip 23 and the second sealing strip 32 are both rubber. Rubber has high elasticity and can return to its original shape after being subjected to external force. This elasticity allows the rubber to fit tightly on the unevenness of the sealing surface and fill tiny gaps, thereby achieving a sealing effect. Rubber has good resistance to water and is not easily penetrated by water. This characteristic gives rubber a significant advantage in water sealing scenarios and can effectively prevent water from leaking through the seal. Rubber has strong resistance to a variety of chemical substances and is not easily corroded. Therefore, in the chemical, pharmaceutical and other industries, rubber seals can withstand the erosion of various chemical media and maintain the stability of the sealing performance.

[0052] This embodiment also provides a commercial vehicle. The commercial vehicle includes the aforementioned dash panel structure and a front frame. The dash panel body 1 is mounted on the front frame. Application of this dash panel structure to a commercial vehicle provides all the benefits of the aforementioned dash panel structure, namely, ensuring reliable air supply to the air conditioning cabinet 4, thereby achieving reliable cooling and heating effects; and ensuring reliable air supply to the radiator 5, thereby effectively ensuring the operating efficiency of the radiator 5 and improving the fuel economy of the entire vehicle.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
