[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.
[0023] Reference Figures 1 to 4 As shown, this utility model provides a defrosting air duct.
[0024] The defrosting duct includes a main body 100, a first welding rib 200, a second welding rib 300, and a third welding rib 400.
[0025] The top of the main body 100 is provided with a downwardly recessed air outlet cavity 110. The top of the air outlet cavity 110 is open. The air outlet cavity 110 includes a main air duct 111 located in the middle and two side air ducts 112 located on the left and right sides. The main air duct 111 connects the two side air ducts 112. The air outlet 120 is located on the front side of the main air duct 111. The air inlet 130 is located at the bottom of the main air duct 111. Defrosting air enters the main air duct 111 from the air inlet 130. The defrosting air in the main air duct 111 is blown to the two side air ducts 112 and the air outlet 120.
[0026] The main air duct 111 is provided with two partition plates, each partition plate is arranged in the front-to-back direction, and there is a space between the bottom of each partition plate and the bottom wall of the main air duct 111, so that the defrosting air in the main air duct 111 can flow to the side air duct 112 through the space between the bottom of the partition plate and the bottom wall of the main air duct 111. The two partition plates are respectively arranged on the left and right sides of the main air duct 111 and above the air inlet 130. Part of the defrosting air blown in by the air inlet 130 is guided to the two side air ducts 112 through the two partition plates.
[0027] The top outer edge of the main body 100 is provided with a flange 101, which extends outward and surrounds the outer periphery of the air outlet cavity 110.
[0028] The bottom of the flange 101 is provided with a plurality of spaced reinforcing ribs 102, which are spaced along the circumference of the air outlet cavity 110, and each reinforcing rib 102 connects the side wall of the air outlet cavity 110 and the bottom of the flange 101.
[0029] The first welding rib 200 is disposed on the top of the flange 101. The first welding rib 200 protrudes upward above the flange 101. The first welding rib 200 is disposed around the outer periphery of the air outlet cavity 110. The distance between the first welding rib 200 and the side wall of the air outlet cavity 110 is equal everywhere.
[0030] The corner of the first weld bead 200 is rounded.
[0031] Rounded corners prevent stress concentration at sharp corners and avoid incomplete welds in the welded structure.
[0032] The second welding rib 300 is disposed on the top of the flange 101. The second welding rib 300 protrudes upward above the flange 101. The second welding rib 300 is disposed around the outer periphery of the first welding rib 200. The distance between the second welding rib 300 and the first welding rib 200 is equal everywhere.
[0033] The corner of the first weld bead 200 is rounded.
[0034] Rounded corners prevent stress concentration at sharp corners and avoid incomplete welds in the welded structure.
[0035] The spacing between the first welding rib 200 and the second welding rib 300 is equal everywhere. The first welding rib 200 and the second welding rib 300 are welded to the bottom of the instrument panel, which helps to form two welding interfaces on the periphery of the air outlet cavity 110. The outer second welding rib 300 ensures that the flange 101 is pulled towards the bottom of the instrument panel, so that the first welding rib 200 can be firmly welded to the bottom of the instrument panel and improve the sealing performance.
[0036] The flange 101 around the main body 100 is used to set the first welding rib 200 and the second welding rib 300. When the first welding rib 200 and the second welding rib 300 are welded to the instrument panel, because the flange 101 has low structural strength, even if the main body 100 or the instrument panel deforms due to stress release, the flange 101 can easily deform so that the first welding rib 200 and the second welding rib 300 can fit tightly against the bottom of the instrument panel, so that the first welding rib 200 and the second welding rib 300 are firmly welded to the instrument panel.
[0037] Multiple reinforcing ribs 102 are provided at the bottom of the flange 101 to improve the structural strength of the flange 101 and prevent the first welding rib 200 and the second welding rib 300 from deforming.
[0038] The reinforcing rib 102 connects to the side wall of the air outlet cavity 110. Multiple reinforcing ribs 102 at the bottom of the flange 101 are used to maintain the basic shape of the flange 101. During the welding process, it is ensured that the first welding rib 200 and the second welding rib 300 can be tightly attached to the bottom of the instrument panel.
[0039] The front side of the main body 100 is provided with multiple extensions 150, each extension 150 extends forward, each extension 150 has a buckle 140 at its bottom, and each extension 150 has a third welding rib 400 on its top surface, which is arranged in the left and right direction.
[0040] In this embodiment, one or more third welding ribs 400 may be provided on the top surface of each extension 150, and at least one third welding rib 400 is provided at a position near the front side of the extension 150.
[0041] Multiple clips 140 on the front bottom of the main body 100 are used to engage with the pre-reserved fastening positions on the instrument panel. After the clips 140 engage with the fastening positions, they are welded to the bottom of the instrument panel by the third welding rib 400 to fix the position of the clips 140, so that the clips 140 are firmly engaged with the fastening positions and to prevent the clips 140 from loosening and causing abnormal noise.
[0042] Multiple clips 140 are provided to engage with multiple fasteners on the dashboard, making the assembly on the front side of the main body 100 more secure.
[0043] The main body 100 of the defrosting duct is provided with a first welding rib 200 and a second welding rib 300 at its top. The first welding rib 200 is arranged around the periphery of the air outlet cavity 110, and the second welding rib 300 is arranged around the periphery of the first welding rib 200. When the top of the main body 100 of the defrosting duct is welded to the dashboard, the first welding rib 200 and the second welding rib 300 are welded together to the bottom of the dashboard, which improves the welding strength between the defrosting duct and the dashboard. Even if the defrosting duct or the dashboard deforms due to stress release, the first welding rib 200 and the second welding rib 300 can be firmly welded to the bottom of the dashboard, preventing the main body 100 from detaching from the dashboard and avoiding air leakage in the air outlet cavity 110.
[0044] This utility model also provides an instrument panel assembly.
[0045] The instrument panel assembly includes an instrument panel and a defrosting air duct as described in the above embodiment. The main body 100 is attached to the bottom of the instrument panel. The first welding rib 200, the second welding rib 300 and the third welding rib 400 are welded to the bottom of the instrument panel. The top of the air outlet cavity 110 is covered by the instrument panel.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
