[0003] [Patent Document 1] JP 2019-137261 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a duct opening structure such as that described in JP 2019-137261 A, when a bezel is attached to the interior trim, in addition to the space required for the structure for pressing the sealing member, space is also required for the structure for attaching the bezel to the interior trim.

[0005] An object of the present disclosure is to provide a duct opening structure that can reduce the space required to attach a bezel to an interior trim while ensuring sealing performance. [Means for solving the problem]

[0006] A duct opening structure according to one aspect of the present disclosure includes an interior trim having an air intake, a bezel attachable to the interior trim, a duct arranged inside the interior trim, a filter attached to the air intake, and a seal member arranged between the interior trim and the duct so that a flow path from the air intake to the duct is blocked from other spaces inside the interior trim, wherein the bezel has a claw portion that engages with the interior trim, and the interior trim has a locking portion that locks the claw portion when the claw portion is inserted, and a rib that has a shape extending from the locking portion toward the seal member and bites into the seal member. Effect of the Invention

[0007] According to the present disclosure, it is possible to provide a duct opening structure that can reduce the space required to attach a bezel to an interior trim while ensuring sealing performance. [Brief description of the drawings]

[0008] [Figure 1] FIG. 2 is a front view showing a schematic view of an interior trim of a duct opening structure in one embodiment of the present disclosure. [Diagram 2] 2 is a cross-sectional view of the duct opening structure taken along line II-II in FIG. 1. [Diagram 3] FIG. 3 is an enlarged view of the area indicated by solid line III in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure will now be described with reference to the accompanying drawings, in which the same or corresponding components are designated by the same reference numerals.

[0010] Fig. 1 is a front view showing a schematic diagram of an interior trim of a duct opening structure according to an embodiment of the present disclosure. Fig. 2 is a cross-sectional view of the duct opening structure at a position shown by line II-II in Fig. 1. Fig. 3 is an enlarged view of the range shown by solid line III in Fig. 2. The duct opening structure is applied, for example, below a seat of a vehicle.

[0011] As shown in FIGS. 1 and 2, the duct opening structure includes an interior trim 10, a duct 20, a seal member 30, a bezel 40, and a filter 50.

[0012] The interior trim 10 is disposed, for example, below a seat of the vehicle. The interior trim 10 is fixed to a vehicle body frame. As shown in FIG. 1, the interior trim 10 has an air intake 10S, a locking portion 12, a rib 14, and a receiving portion 16.

[0013] The air intake 10S is an opening for taking air from within the vehicle cabin into the interior trim 10.

[0014] The locking portion 12 is a portion that locks the bezel 40. As shown in Fig. 1 and Fig. 2, the locking portion 12 is formed around the intake port 10S. The locking portion 12 defines an opening 12h through which a claw portion 46 (described later) of the bezel 40 is inserted. The locking portion 12 locks the claw portion 46 in a state in which the claw portion 46 is inserted.

[0015] The rib 14 is a portion that bites into the seal member 30. The rib 14 has a shape that extends from the engaging portion 12 toward the seal member 30. In other words, the opening 12h opens on the opposite side (the left side in FIG. 2) to the side on which the seal member 30 is located, with the rib 14 as a reference. The rib 14 is formed at a position that bites into the vicinity of the center of the seal member 30.

[0016] The receiving portion 16 is a portion that receives the filter 50. The receiving portion 16 extends from the locking portion 12 toward the center of the air intake port 10S. The receiving portion 16 is formed flat.

[0017] The duct 20 is disposed inside the interior trim 10 and fixed to the vehicle body frame. A blower (not shown) is provided at the downstream end of the duct 20. The cooling air taken in from the duct 20 is used, for example, to cool an electricity storage device mounted on the vehicle. The duct 20 has a holding portion 22 that holds the seal member 30. The holding portion 22 is formed at the upstream end of the duct 20. The holding portion 22 is formed flat.

[0018] The seal member 30 is disposed between the interior trim 10 and the duct 20 so that the flow path from the intake port 10S to the duct 20 is blocked from other spaces inside the interior trim 10. The seal member 30 is made of a sponge or the like. The seal member 30 is fixed to the retaining portion 22. As shown in Figs. 2 and 3, the rib 14 is engaged with the seal member 30.

[0019] The bezel 40 is attached to the interior trim 10 so as to cover the air intake 10S. As shown in Figures 2 and 3, the bezel 40 has a ventilation portion 42, a pressing portion 44, a claw portion 46, and a retaining claw (not shown).

[0020] The ventilation portion 42 allows air to pass through. The ventilation portion 42 is formed, for example, in a lattice shape.

[0021] The pressing portion 44 is a portion that presses the filter 50 against the interior trim 10. The pressing portion 44 is formed around the periphery of the ventilation portion 42. The pressing portion 44 is formed flat. The pressing portion 44, together with the receiving portion 16, holds the filter 50 in a sandwiched manner.

[0022] The claw portion 46 is a portion that engages with the interior trim 10. The claw portion 46 is engaged with the locking portion 12 in a state where it is inserted through the opening 12h. The claw portion 46 is provided around the pressing portion 44.

[0023] The retaining claws are portions that retain the filter 50. The interior trim 10 is formed with recesses for avoiding interference between the retaining claws and the claw portions 46.

[0024] The filter 50 is attached to the air intake 10S. Specifically, the filter 50 is attached to the air intake 10S while being held by the holding claws of the bezel 40. As shown in Fig. 2 and Fig. 3, the filter 50 has a filter body 51 and a flange 52 formed around the filter body 51. The flange 52 is clamped between the receiving portion 16 and the pressing portion 44.

[0025] As described above, in the duct opening structure of this embodiment, the rib 14 is embedded in the seal member 30, thereby effectively ensuring sealing performance, and since the rib 14 extends from the engaging portion 12 that engages the claw portion 46 toward the seal member 30, the space required for the structure to attach the bezel 40 to the interior trim 10 is reduced.

[0026] In the above embodiment, the relationship between the rib 14 and the retaining portion 22 may be reversed. In other words, the interior trim 10 may be provided with a retaining portion that retains the seal member 30 instead of the rib 14, and a rib may be provided at the end of the duct 20.

[0027] It will be appreciated by those skilled in the art that the exemplary embodiments described above are examples of the following aspects.

[0028] The duct opening structure in the above embodiment includes an interior trim having an air intake, a bezel attachable to the interior trim, a duct arranged inside the interior trim, a filter attached to the air intake, and a seal member arranged between the interior trim and the duct so that a flow path from the air intake to the duct is blocked from other spaces inside the interior trim, and the bezel has a claw portion that engages with the interior trim, and the interior trim has a locking portion that locks the claw portion when the claw portion is inserted, and a rib that has a shape extending from the locking portion toward the seal member and bites into the seal member.

[0029] In this duct opening structure, the ribs are embedded in the sealing member, thereby effectively ensuring sealing performance, and since the ribs extend from the engagement portion that engages the claw portion toward the sealing member, the space required for the structure to attach the bezel to the interior trim is reduced.

[0030] It should be noted that the embodiments disclosed herein are illustrative in all respects and should not be considered as limiting. The scope of the present invention is indicated by the claims, not by the description of the embodiments above, and further includes all modifications within the meaning and scope of the claims.
