Description

The technology disclosed herein relates to a structure for mounting a filter member on a duct mounted in a vehicle.

Conventionally, as a structure for attaching a filter member to a duct mounted on a vehicle, the one disclosed in Patent Document 1 below is known. Patent Document 1 discloses a structure including an air conditioning duct and a filter inserted into the air conditioning duct from the filter insertion port of the air conditioning duct.

Jikkenhei 6-12133

However, in the structure disclosed in Patent Document 1, since the filter is installed in the air conditioning duct, it is necessary for the operator to reach out from the outside and perform the filter replacement work in the vicinity of the air conditioning duct. A large number of parts are mounted on a vehicle in a limited interior space, and parts such as ducts are generally arranged in a position that is difficult to reach from the outside in the limited interior space. Therefore, in the mounting structure of the filter member that requires the replacement work in the vicinity of the duct, the workability related to the replacement of the filter member is poor.

As a structure in which the filter member is not installed in the duct, a structure in which the filter member is installed in the opening of the duct can be considered. For example, when the filter member is attached to the opening of the duct that opens toward the vehicle interior space, a structure in which the filter member is attached to the member constituting the vehicle interior space can be considered. However, in such a structure, an error in the arrangement of the duct with respect to the vehicle interior space creates a gap between the filter member and the opening of the duct, and air that does not pass through the filter member flows into the duct through the gap, or There is concern that it will flow out of the duct.

The technique disclosed in the present specification has been completed based on the above circumstances, and the filter member can be easily replaced, and clean air can flow in or out. It is an object of the present invention to provide a mounting structure for a flexible filter member.

The mounting structure of the filter member disclosed in the present specification is a mounting structure for mounting the filter member to a duct mounted on the vehicle, and the duct has an opening that opens toward the space inside the vehicle and an opening. It has a flange portion extending in the radial direction from the mouth edge of the opening, and the opening is covered from the vehicle interior space side by a cover member having a ventilation hole, and the cover member is attached to the duct. The filter member is attached to the opening while sandwiching the outer peripheral edge portion of the filter member between the cover member and the flange portion.

According to the technique disclosed in the present specification, since the filter member is attached to the opening while sandwiching the outer peripheral edge portion between the cover member and the flange portion, the cover member is engaged with and disengaged from the vehicle interior space side with respect to the duct. As a result, the filter member can be easily replaced. Further, since the duct is provided with a flange portion to sandwich the outer peripheral edge portion of the filter member with the cover member locked to the duct, the filter member is caused by an error in the arrangement of the duct with respect to the vehicle interior space. It is possible to suppress a situation in which a gap is formed between the opening and the opening. Therefore, it is possible to suppress a situation in which air that does not pass through the filter member flows into or out of the duct through the gap generated between the filter member and the opening, and clean air flows into the duct or flows into the duct. It can be leaked.

In the above configuration, the flange portion is provided with an elastically deformable seal member, and the cover member and the flange portion are provided with the seal member interposed between the flange portion and the outer peripheral edge portion. The structure may be such that the outer peripheral edge portion is sandwiched between the two. According to such a configuration, the gap between the outer peripheral edge portion and the flange portion can be filled by the seal member, and the filter member can be reliably sandwiched by the flange portion by the elastic force of the seal member. As a result, it is possible to prevent the air that does not pass through the filter member from flowing into or out of the duct from the gap between the cover member and the flange portion or the gap that is unintentionally generated due to the misalignment of the filter member. can do.

In the above configuration, the vehicle interior space is composed of a vehicle interior material whose inner surface is plate-shaped, and the vehicle interior material has a communication port communicating with the opening of the duct in a flat region. The cover member may have a structure that covers the rim of the communication port from the vehicle interior space side in a state of being locked to the duct. According to such a configuration, even if the position of the duct is displaced in the plane direction of the planar region of the vehicle interior material, the configuration in which the cover member covers the mouth edge of the communication port can be maintained. .. Therefore, it is possible to suppress a situation in which the rim of the communication port is exposed to the vehicle interior space due to an error in the arrangement of the duct, and the design of the vehicle interior space is impaired.

In the above configuration, the vehicle interior space is a luggage compartment in the vehicle, and the cover member may be arranged on the ceiling of the luggage compartment. If the filter member is attached only to the duct regardless of the cover member, it is necessary to reach out from the opening of the luggage compartment and replace the filter member near the ceiling of the luggage compartment, resulting in poor workability. On the other hand, according to the technique disclosed in the present specification, the filter member is attached to and detached from the cover member at hand, and the cover member is arranged on the ceiling of the luggage compartment so that the filter member can be attached to the opening. It can be attached and has excellent workability for replacing filter members.

According to the technique disclosed herein, it is possible to provide a mounting structure of a filter member capable of easily replacing the filter member and allowing clean air to flow in or out.

In the mounting structure of the filter member 50, as shown in FIG. 6, the cover member 40 is locked to the duct 30, and the outer peripheral edge portion 53 of the filter member 50 is placed between the cover member 40 and the flange portion 32. The structure is such that the filter member 50 is attached to the intake port 31 while sandwiching the filter member 50. Further, in the mounting structure of the filter member 50 of the present embodiment, the seal member 33 is interposed between the flange portion 32 and the outer peripheral edge portion 53, and the outer peripheral edge portion 53 is sandwiched between the cover member 40 and the flange portion 32. It has a structure. Hereinafter, a mode in which the filter member 50 is attached to the duct 30 will be described.

Prior to attaching the filter member 50 to the duct 30, the duct 30 is attached to the vehicle panel 10A via the fastening member 17, as shown in FIG. Further, the ceiling portion 23 of the front trim 20 is attached to the vehicle panel 10A via the fastening member 18. Both the duct 30 and the ceiling portion 23 are fastened to the vehicle panel 10A from below the vehicle, and the intake port 31 of the duct 30 and the communication port 24 of the ceiling portion 23 have a relatively large error in arrangement in the vehicle vertical direction. Although it is small, the placement error in the vehicle front-rear direction and the vehicle width direction is relatively large. The communication port 24 of the ceiling portion 23 is formed with a clearance with respect to the intake port 31 of the duct 30, and the communication port 24 to the intake port 31 are formed regardless of an error in the arrangement of the duct 30 and the front trim 20. Is exposed in the luggage compartment 11.

When attaching the filter member 50 to the duct 30, first, as shown in FIG. 4, the filter member 50 is attached to the cover member 40. Specifically, the hooking portion 43 of the cover member 40 is inserted into the hooking hole 53A of the filter member 50, and the filter member 50 is positioned with respect to the cover member 40 so as not to be movable in the surface direction of the facing plate portion 41. In this state, the outer peripheral edge portion 53 of the filter member 50 is laminated on the back surface of the facing plate portion 41 of the cover member 40, and the filtration portion 51 of the filter member 50 is arranged at a position where it overlaps with the ventilation hole 40A of the cover member 40. The cover member 40 is a member having a higher rigidity than the filter member 50, and the cover member 40 reinforces the cover member 40 as a frame of the blocked filter member 50 in addition to the function of covering the intake port 31 of the duct 30. It can be said that it has a function. That is, the filter member 50 is attached to and detached from the duct 30 while being held by the cover member 40, so that the filter member 50 can be easily handled.

Subsequently, as shown in FIG. 6, the cover member 40 to which the filter member 50 is attached is locked with respect to the duct 30. The cover member 40 is assembled to the duct 30 by drawing an arc-shaped assembly locus from the luggage compartment 11 side (below the vehicle) with the front end of the vehicle as an axis, and is assembled from the fitting portions 47 and the locking portions 49, 49. Locked. Specifically, the fitting portion 47 of the cover member 40 is inserted into the fitting hole 37A of the duct 30 from the rear of the vehicle. Then, at the position where the contact portion 47A abuts on the hole edge of the fitting hole 37A, the cover member 40 is rotated toward the upper side of the vehicle around the portion of the fitting portion 47 located in the fitting hole 37A. Let me. Then, as the cover member 40 approaches the horizontal posture, the locking portion 49 of the cover member 40 enters the locking hole 39A of the duct 30. The locking portion 49 is pressed against the inner peripheral surface of the locking hole 39A in the process of entering the locking hole 39A, and is elastically deformed so that the bending angle of the bent portion becomes smaller, while the claw portion 49A is pressed. It is inserted into the locking hole 39A until it passes through the locking hole 39A. When the claw portion 49A passes through the locking hole 39A and reaches above the vehicle of the locked portion 39, the locking portion 49 elastically returns and the claw portion 49A is locked to the hole edge of the locking hole 39A. It will be in a state of being. An operator who performs the work of locking the cover member 40 to the duct 30 will reach out from the luggage compartment opening 11A and perform this work in the vicinity of the ceiling portion 23 which is difficult to see from the luggage compartment opening 11A. (See FIG. 2). In the present embodiment, the fitting portion 47 is fitted into the fitting hole 37A at the front end portion of the vehicle, which is relatively easy to see on the ceiling portion 23, and after that, the locking hole 39A is formed only by the rotating operation of the cover member 40. On the other hand, the locking portion 49 can be locked.

In the process of locking the cover member 40 with respect to the duct 30, the seal member 33 is compressed between the flange portion 32 and the facing plate portion 41 to create a gap between the flange portion 32 and the cover member 40. Seal (see FIG. 6). Then, the outer peripheral edge portion 53 of the filter member 50 is sandwiched between the facing plate portion 41 and the flange portion 32 with the seal member 33 interposed between the outer peripheral edge portion 53 and the flange portion 32. Then, together with the elastic force of the seal member 33, the outer peripheral edge portion 53 of the filter member 50 is sandwiched between the flange portion 32 and the cover member 40. Further, in the present embodiment, the seal member 33 is set at a position overlapping the hook portion 43 of the cover member 40 and the hook hole 53A of the filter member 50, and the hook portion 43 and the hook hole are set by the seal member 33. 53A is blocked.

When the cover member 40 is locked to the duct 30, as shown in FIG. 6, the filter member 50 is sealed around the filtration unit 51 by the seal member 33, and the filtration unit 51 is inside the intake port 31. In the air intake port 31, the intake port 31 is closed so as to be able to ventilate. Since the filtration unit 51 has a fold-shaped shape, the contact area with the air that passes through the ventilation hole 40A and flows into the intake port 31 is increased as compared with the case where the filtration unit 51 has a flat shape, for example. The filtration efficiency is good.

Then, as shown in FIG. 2, the cover member 40 is configured to cover the mouth edge 24A of the communication port 24 from the luggage compartment 11 side in a state of being locked to the duct 30. Further, the cover member 40 is arranged on the ceiling portion 23 of the luggage compartment 11. As described above, the attachment of the filter member 50 to the duct 30 is completed.

When the filter member 50 is replaced after an arbitrary period of use, the locking portion 49 of the cover member 40 is elastically deformed from the luggage compartment 11 side to catch the claw portion 49A and the locking hole 39A on the hole edge. remove. Then, the cover member 40 is rotated toward the luggage compartment 11 side (lower side of the vehicle) about the portion of the fitting portion 47 located in the fitting hole 37A, and is pulled out from the locking hole 39A of the locking portion 49. .. After that, the fitting portion 47 is pulled out from the fitting hole 37A to the rear of the vehicle to release the locked state of the cover member 40 with respect to the duct 30. At this time, the filter member 50 is held by the cover member 40, and is attached to the cover member 40 and removed from the intake port 31. Then, the operator removes the used filter member 50 from the cover member 40 at hand and attaches a new filter member 50 to the cover member 40. The mode in which the new filter member 50 is attached to the intake port 31 is the same as the above-described mode, and the description thereof will be omitted. With the above, the replacement of the filter member 50 is completed.

Subsequently, the effect of this embodiment will be described. According to the present embodiment, since the filter member 50 is attached to the intake port 31 while sandwiching the outer peripheral edge portion 53 between the cover member 40 and the flange portion 32, the cover member 40 is placed on the luggage compartment 11 side with respect to the duct 30. The filter member 50 can be easily replaced by engaging and disengaging from the filter member 50. Further, since the duct 30 is provided with the flange portion 32 so as to sandwich the outer peripheral edge portion 53 of the filter member 50 with the cover member 40 locked to the duct 30, the duct 30 with respect to the luggage compartment 11 is provided. It is possible to suppress a situation in which a gap is generated between the filter member 50 and the intake port 31 due to an arrangement error. Therefore, it is possible to suppress a situation in which air that does not pass through the filter member 50 flows into the duct 30 through a gap generated between the filter member 50 and the intake port 31, and clean air can flow into the duct 30. Can be done.

If the duct 30 does not have the flange portion 32, for example, a configuration is conceivable in which a frame-shaped member surrounding the intake port 31 is set in the luggage compartment 11. Then, the cover member 40 is locked to the frame-shaped member, the filter member 50 is arranged between the frame-shaped member and the cover member 40, and the end surface of the frame-shaped member and the duct 30 (the air passage 30B is formed). It is conceivable to have a structure in which the seal member 33 is arranged between the end face of the wall portion and the wall portion. However, in such a structure, the cover member 40 is not locked to the duct 30, and a frame-shaped member or the like is interposed between the cover member 40 and the duct 30, so that the seal is sealed due to an error in the arrangement of these members. It is difficult to secure the sealing property between the cover member 40 and the duct 30 by the member 33. Further, the filter member 50 is arranged between the frame-shaped member and the cover member 40 without interposing the seal member 33, and due to a dimensional error or deformation of the frame-shaped member and the cover member 40, the filter member 50 and the filter member 50 There is a risk that a gap will be created between the frame-shaped member and air that does not pass through the filter member 50 will flow into the duct 30. That is, in the structure in which the duct 30 does not have the flange portion 32 and the frame-shaped member is set in the luggage compartment 11, the low robustness related to the sealing performance becomes a problem. On the other hand, in the present embodiment, since the flange portion 32 is provided in the duct 30 and the cover member 40 is locked to the duct 30, the number of parts related to the frame-shaped member can be reduced and the sealing performance can be reduced. It can contribute to the improvement of robustness related to. Further, it is not necessary to increase the size of the seal member 33 in order to ensure such robustness, and the size of the seal member 33 can be appropriately set according to the dimensions between the flange portion 32 and the cover member 40. Therefore, the size of the seal member 33 can be reduced.

Further, in the present embodiment, the seal member 33 is interposed between the flange portion 32 and the outer peripheral edge portion 53, and the outer peripheral edge portion 53 is sandwiched between the cover member 40 and the flange portion 32. Therefore, the seal member 33 fills the gap between the outer peripheral edge portion 53 and the flange portion 32, and the elastic force of the seal member 33 can reliably hold the filter member 50 between the flange portions 32. As a result, it is possible to prevent the air that does not pass through the filter member 50 from flowing into the duct 30 from the gap between the cover member 40 and the flange portion 32 or the gap that is unintentionally generated due to the misalignment of the filter member 50. Can be done.

Further, in the present embodiment, the communication port 24 is formed in the ceiling portion 23 which is a flat region, and the mouth edge 24A of the communication port 24 is used as a luggage compartment in a state where the cover member 40 is locked to the duct 30. Since it covers from the 11 side, even if the position of the duct 30 shifts in the plane direction of the ceiling portion 23, the structure in which the cover member 40 covers the mouth edge 24A of the communication port 24 can be maintained. Therefore, it is possible to suppress a situation in which the mouth edge 24A of the communication port 24 is exposed to the luggage compartment 11 due to an error in the arrangement of the duct 30, and the design of the luggage compartment 11 is impaired.

Further, in the present embodiment, the cover member 40 is arranged on the ceiling portion 23 of the luggage compartment 11. If the filter member 50 is directly attached to the duct 30 regardless of the cover member 40, the filter member 50 is replaced by reaching out from the luggage compartment opening 11A near the ceiling portion 23 of the luggage compartment 11. It is necessary and workability is poor. On the other hand, according to the present embodiment, the filter member 50 is attached to and detached from the cover member 40 at hand, and the cover member 40 is arranged on the ceiling portion 23 of the luggage compartment 11, so that the filter member is attached to the intake port 31. 50 can be attached, and the workability of replacing the filter member 50 is excellent. Further, in the present embodiment, since the filter member 50 is attached to the intake port 31 that opens in the ceiling portion 23, it is difficult for an external force to act unintentionally around the intake port 31 due to contact with an occupant or a mounted object. , There is little need to receive such an external force by the above-mentioned frame-shaped member, and the frame-shaped member can be preferably abolished.
