Description

Technical Field

[0001] This utility model relates to automobile body structure, specifically to a pillar trim panel and a vehicle. Background Technology

[0002] The function of a car's air ducts is not only to work with the air conditioning system to deliver airflow to the cabin to regulate temperature, but also to provide a safety function for defrosting and defogging the entire vehicle: when fog or frost appears on the windshield or side windows, activating the air conditioning defrost and defogging function will deliver sufficient airflow through the defrost ducts to dissipate and remove the fog and frost from the windshield and side windows, maintaining the driver's visibility and ensuring driving safety.

[0003] Vehicle defrosting and defogging ducts are divided into windshield defrosting ducts and side window defrosting ducts. Generally, depending on the vehicle's styling, there are two common arrangements for the side window defrosting ducts: either on the dashboard area near the windows or on the A-pillar trim areas on the left and right sides of the vehicle.

[0004] There is a common risk associated with the type of defrosting ducts located on the A-pillar trim panels: usually, due to the limited internal space of the pillar trim panels, the cross-sectional area of ​​the duct cavity is small, resulting in a large pressure loss of the transmitted air. This causes the process of dissipating frost and fog to be slow or even fails to meet the defogging requirements of the side windows, resulting in poor visibility for drivers and passengers and posing a significant driving safety hazard. Therefore, untimely defrosting is a major pain point in the overall vehicle safety and a major complaint in the aftermarket.

[0005] CN211809416U discloses an automotive A-pillar interior panel assembly, including an A-pillar interior panel, a side defrost vent, and a side defrost duct. The lower part of the A-pillar interior panel, near the window glass, has a recessed platform with vent mounting holes. The side defrost vent is located within the recessed platform and engages with the edge of the vent mounting hole. The side defrost duct communicates with the side defrost vent and is located behind it. A duct mounting hole is provided on the connecting edge of the duct. The inner side of the A-pillar interior panel, near the recessed platform, has a connecting post that mates with the duct mounting hole. The connecting post is inserted into the duct mounting hole and welded to the edge of the duct mounting hole. Undoubtedly, the technical solution disclosed in the above patent document is a beneficial attempt in its respective technical field. However, this technical solution uses a closed and complete duct structure combined with the pillar trim panel body to form an accessory assembly, and does not provide an optimization solution for the airflow of the defrost duct.

Detailed Implementation

[0034] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1-9 As shown, a column decorative panel 1 in this embodiment includes a panel body 11 and a duct device 12. The duct device 12 has an opening structure 121 on one side facing the panel body 11. The opening structure 121 is connected to the inner wall of the panel body 11 so that the opening structure 121 and the panel body 11 form an air guide channel. The air inlet end of the duct device 12 extends downward from the lower end of the panel body 11.

[0036] By setting an opening structure 121 on the air duct device 12 and connecting it with the inner wall of the trim panel body 11, a cavity structure is formed between the opening structure 121 and the trim panel body 11 as an air guide channel. This eliminates the need for the wall structure on the opening structure 121 side of the air duct device 12 and the gap between the air duct device 12 and the inner wall of the trim panel body 11. The space utilization rate inside the pillar trim panel 1 is high, which greatly increases the cross-sectional area of ​​the air guide channel and improves the air volume of the air guide channel. This increases the air volume blown towards the side defrosting area 41 of the side window glass 4, which is beneficial for defrosting and defogging the window and can improve driving safety.

[0037] The open structure 121 optimizes the molding process of the duct device 12. A closed duct device 12 requires blow molding, while the open structure 121 in this embodiment allows for injection molding. The rectangular air inlet frame 122, the U-shaped air outlet frame 124, and the main body 127 are directly manufactured using injection molding. This allows for a conversion from the original blow molding process to a standard injection molding process. This not only allows for the design of multi-cavity molds, improving production efficiency, but also enables continuous production compared to blow molding, further enhancing efficiency. The converted injection molding process offers higher dimensional accuracy, better surface quality, and a significantly improved parts yield rate compared to the original blow molding process. Furthermore, the open structure 121 reduces material usage compared to a closed duct structure, achieving weight reduction. Therefore, the column trim panel 1 in this embodiment offers advantages in weight reduction, improved production efficiency, increased yield rate, and cost reduction.

[0038] The air inlet end of the duct device 12 extends downward from the lower end of the trim panel body 11, which facilitates docking with the air supply pipe connector 32 below the instrument panel 31 of the air supply system 3. The structure is simple and easy to assemble.

[0039] In this embodiment, the air inlet end of the duct device 12 is provided with a rectangular air inlet frame 122 and a first sealing member 123.

The rectangular air inlet frame 122 and the first sealing member 123 can be connected by adhesive bonding. The rectangular air inlet frame 122 and the corresponding first sealing member 123 can improve the sealing performance between the air inlet end of the duct device 12 and the air supply system 3, preventing leakage.

[0040] In this embodiment, the rectangular air inlet frame 122 includes a first frame portion 1221, a second frame portion 1222, a third frame portion 1223, and a fourth frame portion 1224 that are sequentially enclosed. The upper side of the first frame portion 1221, the upper side of the second frame portion 1222, and the upper side of the third frame portion 1223 are all connected to the air duct device 12, and the upper side of the fourth frame portion 1224 abuts against the decorative panel body 11.

[0041] The surface of the decorative panel body 11 near the fourth frame 1224 also abuts against the air supply pipe connector 32, further preventing the sealing performance of the connection between the column decorative panel 1, the air duct device 12 and the air supply system 3.

[0043] The air outlet end of the air duct device 12 is docked with the air outlet structure 111 of the trim panel. The air outlet end of the air duct device 12 and the air outlet structure 111 of the trim panel both face the side defrosting area 41 of the side window glass 4, and are used to guide the air flow in the air guiding channel to blow towards the side defrosting area 41 of the side window glass 4.

[0044] In this embodiment, the air outlet end of the air duct device 12 is provided with a U-shaped air outlet frame 124 and a second sealing member 125. The second sealing member 125 is connected to the U-shaped air outlet frame 124. Both the first sealing member 123 and the middle part of the rectangular air inlet frame 122 are provided with air outlet openings communicating with the air guiding channel. The U-shaped air outlet frame 124 and the second sealing member 125 can be connected by bonding. The U-shaped air outlet frame 124 and the corresponding second sealing member 125 can improve the sealing performance between the air outlet end of the air duct device 12 and the trim panel body 11, prevent leakage, and ensure that the air flow flows out from the air outlet structure 111 of the trim panel.

[0045] In this embodiment, the U-shaped air outlet frame 124 includes a bottom wall 1241, and further includes a first extension side 1242, a second extension side 1243, and a third extension side 1244 that are sequentially enclosed on the bottom wall 1241. The second sealing member 125 is simultaneously connected to the bottom wall 1241, the first extension side 1242, the second extension side 1243, and the third extension side 1244.

[0046] In this embodiment, the air duct device 12 includes a device main body 127. The device main body 127 includes a first side wall 1271, a second side wall 1272, and a third side wall 1273. The head ends of the second side wall 1272 and the third side wall 1273 are both connected to the first side wall 1271. The tail ends of the second side wall 1272 and the third side wall 1273 both face the direction close to the trim panel body 11. The first side wall 1271, the second side wall 1272, and the third side wall 1273 form a structure with a "J" - shaped cross-section, thereby forming an opening structure 121. The sides of the first side wall 1271, the second side wall 1272, and the third side wall 1273 facing the air inlet end are connected to the rectangular air inlet frame 122, and the sides of the first side wall 1271, the second side wall 1272, and the third side wall 1273 facing the air outlet end are connected to the U-shaped air outlet frame 124.

[0047] In this embodiment, a first flange 1274 is provided at the end of the second sidewall 1272, and a first sealing strip 128 is provided between the first flange 1274 and the decorative panel body 11; a second flange 1275 is provided at the end of the third sidewall 1273, and a second sealing strip 129 is provided between the second flange 1275 and the decorative panel body 11. The first flange 1274 and the first sealing strip 128 can be connected by adhesive, and the second flange 1275 and the second sealing strip 129 can be connected by adhesive, which can improve the sealing performance between the decorative panel body 11 and the air duct device 12.

[0048] In this embodiment, mounting ears 1276 are respectively provided on the first flange 1274 and the second flange 1275, and mounting supports 112 are respectively provided on the trim panel body 11 at the positions of each mounting ear 1276.
