Description

  The technique disclosed by this specification is related with the attachment structure of the filter member with respect to the duct mounted in the vehicle.

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

Japanese Utility Model Publication No. 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 near the air conditioning duct. Many parts are mounted on a vehicle in a limited interior space, and parts such as ducts are generally arranged in a limited interior space so that they are difficult to reach from the outside. For this reason, in the filter member mounting structure that requires replacement work in the vicinity of the duct, workability related to replacement of the filter member is poor.

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

  The technology disclosed in this specification has been completed based on the above-described circumstances, and the filter member can be easily replaced and clean air can be introduced or discharged. It is an object of the present invention to provide a simple filter member mounting structure.

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

  According to the technique disclosed in the present specification, the filter member is attached to the opening while the outer peripheral edge is sandwiched between the cover member and the flange portion, so that the cover member is disengaged from the interior space side with respect to the duct. Thus, the filter member can be easily replaced. Further, since the flange portion is provided in the duct and the outer peripheral edge portion of the filter member is sandwiched between the flange and the cover member that is locked to the duct, the filter member is caused by an error in the arrangement of the duct with respect to the interior space. It is possible to suppress a situation in which a gap is generated between the opening and the opening. For this reason, it is possible to suppress the situation where air that does not pass through the filter member from the gap formed between the filter member and the opening portion flows into the duct or flows out of the duct. Can be drained.

  In the above configuration, an elastically deformable seal member is disposed in the flange portion, and the cover member and the flange portion are interposed between the flange portion and the outer peripheral edge portion. A structure in which the outer peripheral edge portion is sandwiched between them may be employed. According to such a configuration, the gap between the outer peripheral edge portion and the flange portion can be filled with the seal member, and the filter member can be securely held by the flange portion by the elastic force of the seal member. As a result, air that does not pass through the filter member is prevented from flowing into or out of the duct from the gap between the cover member and the flange portion or unintentionally generated due to the displacement of the filter member. can do.

  In the above configuration, the interior space of the vehicle interior is configured by a plate-like vehicle interior material, and the vehicle interior material has a communication port that communicates with the opening of the duct in a planar area. And the structure which covers the edge of the said communicating port from the vehicle interior space side in the state latched by the said duct may be sufficient. According to such a configuration, even if the position of the duct is deviated in the plane direction of the planar area of the vehicle interior material, the configuration in which the cover member covers the rim of the communication port can be maintained. . For this reason, it is possible to suppress a situation in which the edge of the communication port is exposed to the interior space due to an error in the arrangement of the duct and the design of the interior space is impaired.

  The said structure WHEREIN: The said vehicle interior space is made into the cargo compartment in a vehicle, The said cover member may be arrange | positioned by the ceiling part of the said cargo compartment. Temporarily, in the structure where the filter member is attached only to the duct regardless of the cover member, it is necessary to exchange the filter member in the vicinity of the ceiling of the cargo compartment by reaching out from the cargo compartment opening, and workability is poor. On the other hand, according to the technique disclosed in this specification, the filter member is attached to and detached from the cover member at hand, and the cover member is disposed on the ceiling of the cargo compartment, so that the filter member can be attached to the opening. It can be attached and excels in workability for exchanging filter members.

  According to the technology disclosed in the present specification, it is possible to provide a filter member mounting structure that can easily replace the filter member and allow clean air to flow in or out.

An adhesive layer (not shown) is provided on the lower surface of the flange portion 32. Is attached through. The seal member 33 is configured such that the thickness dimension is larger than the dimension between the flange portion 32 and the cover member 40 (the opposing plate portion 41).

  Further, as shown in FIG. 6, the duct 30 is provided with a fitted portion 37 to which the fitting portion 47 of the cover member 40 is fitted on the vehicle front side of the intake port 31. Locked portions 39 and 39 to which the locking portions 49 of the cover member 40 are locked are provided on the rear side of the vehicle. The fitting hole 37A is arranged in the vicinity of the central portion in the vehicle width direction of the intake port 31, and the locking holes 39A and 39A are arranged on both sides in the vehicle width direction with respect to the fitting hole 37A. That is, the duct 30 is provided with engagement portions for locking the cover member 40 at three locations on the edge 31A of the intake port 31.

  As shown in FIG. 6, the fitted portion 37 has a wall shape that rises from the flange portion 32 toward the vehicle lower side, and has a fitting hole 37 </ b> A that opens toward the rear of the vehicle. The fitting hole 37A is a slit-like through hole extending in the vehicle width direction. The fitting hole 37 </ b> A is formed at a position protruding downward from the ceiling portion 23 in the vehicle, and is arranged in the cargo compartment 11 near the corner portions of the front wall portion 21 and the ceiling portion 23.

  As shown in FIG. 6, the locked portion 39 has an extending piece shape extending from the rear side of the vehicle edge 31 </ b> A of the air inlet 31 toward the vehicle rear side, and is open toward the vehicle lower side. Locking holes 39A, 39A. The locking hole 39A is a through hole having a rectangular shape in plan view. A portion of the ceiling portion 23 that overlaps with the locking hole 39 </ b> A is cut out, and the locking hole 39 </ b> A is arranged so as to face the luggage compartment 11 on the ceiling surface.

  As shown in FIGS. 3 and 5, the cover member 40 is a plate-shaped member made of synthetic resin, and has a plurality of air holes 40 </ b> A at positions that cover the air inlet 31. The cover member 40 has a rectangular shape in plan view that is slightly larger than the communication port 24 of the ceiling portion 23, and has a counter plate portion 41 that faces the flange portion 32 so as to surround the vent hole 40A. In addition, the counter plate portion 41 is provided with two hook portions 43 for hooking the filter member 50 on two sides in the vehicle width direction. The latching portion 43 has a shape in which the counter plate portion 41 is partially cut out, rises toward the back surface side, and bends toward the outer peripheral side.

  As shown in FIGS. 3 and 6, the cover member 40 is provided with a fitting portion 47 that fits in the fitting hole 37 </ b> A of the duct 30 at the front end portion of the vehicle, and the engagement of the duct 30 at the rear end portion of the vehicle. Locking portions 49 and 49 that are locked to the stop holes 39A are provided. The fitting portion 47 has an extending piece shape extending from the opposing plate portion 41 toward the front of the vehicle, and has a contact portion 47A that contacts the hole edge of the fitting hole 37A on the lower surface. The locking portion 49 has a bent piece shape that is bent in a V shape in a sectional view, and is formed in a posture in which the bent portion is directed upward of the vehicle. The locking part 49 is configured to be elastically deformable so as to reduce the bending angle of the bent part. The locking portion 49 is provided with a claw portion 49A that is secured to the hole edge of the locking hole 39A on the rear surface of the vehicle. A mode in which the fitting portion 47 and the locking portion 49 are engaged with the fitting hole 37A and the locking hole 39A will be described later.

  As shown in FIGS. 4 and 5, the filter member 50 includes a filtering part 51 that can remove dust from passing air, and an outer peripheral edge part 53 that extends along the outer periphery of the filtering part 51. The filtration part 51 consists of a filter medium containing the entangled fiber, and forms a filter medium in the shape of a fold. The outer peripheral edge 53 has a sheet shape formed integrally with the filtration part 51 and extends on the same plane as the vehicle lower end of the filtration part 51. The outer peripheral edge 53 has a slit-like hooking hole 53A into which the hooking part 43 of the cover member 40 can be inserted.

  As shown in FIG. 6, the attachment structure of the filter member 50 is such that the cover member 40 is locked to the duct 30, and the outer peripheral edge 53 of the filter member 50 is interposed between the cover member 40 and the flange portion 32. The filter member 50 is attached to the air inlet 31 while being sandwiched. Further, in the mounting structure of the filter member 50 according to the present embodiment, the outer peripheral edge 53 is sandwiched between the cover member 40 and the flange 32 by interposing the seal member 33 between the flange 32 and the outer peripheral edge 53. 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 10 </ b> A via a fastening member 18. Both the duct 30 and the ceiling portion 23 are fastened to the vehicle panel 10A from the lower side of the vehicle, and the intake port 31 of the duct 30 and the communication port 24 of the ceiling portion 23 are relatively free from errors in arrangement in the vehicle vertical direction. Although small, an error in arrangement 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 air intake port 31 of the duct 30, and the communication port 24 to the air intake port 31 are not affected by errors in the arrangement of the duct 30 and the front trim 20. Is exposed in the luggage compartment 11.

  When the filter member 50 is attached to the duct 30, the filter member 50 is first attached to the cover member 40 as shown in FIG. 4. Specifically, the latching portion 43 of the cover member 40 is inserted into the latching hole 53 </ b> A of the filter member 50, and the filter member 50 is positioned so as not to move in the surface direction of the counter plate portion 41 with respect to the cover member 40. In this state, the outer peripheral edge portion 53 of the filter member 50 is laminated on the back surface of the counter plate portion 41 of the cover member 40, and the filtration portion 51 of the filter member 50 is disposed at a position where it overlaps the vent hole 40 </ b> A of the cover member 40. The cover member 40 is a member having rigidity higher than that of the filter member 50, and the cover member 40 reinforces this as a frame of the hooked filter member 50 in addition to the function of covering the air inlet 31 of the duct 30. It can be said that it has a function. That is, the filter member 50 is configured to be easily handled by being attached to and detached from the duct 30 while being held by the cover member 40.

  Subsequently, as shown in FIG. 6, the cover member 40 to which the filter member 50 is attached is locked to the duct 30. The cover member 40 is assembled to the duct 30 while drawing an arcuate assembly locus from the cargo compartment 11 side (below the vehicle) with the front end of the vehicle as an axis, and from the fitting portion 47 and the locking portions 49 and 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 is in contact with the hole edge of the fitting hole 37A, the cover member 40 is rotated upward with the portion located in the fitting hole 37A in the fitting portion 47 as an axis. Let Then, the locking part 49 of the cover member 40 enters the locking hole 39 </ b> A of the duct 30 when the cover member 40 approaches the horizontal posture. The engaging portion 49 is pressed against the inner peripheral surface of the engaging hole 39A in the process of entering the engaging hole 39A, and is elastically deformed so that the bending angle of the bending portion becomes small. 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 the vehicle upper portion of the locked portion 39, the locking portion 49 is elastically restored, and the claw portion 49A is locked to the hole edge of the locking hole 39A. It becomes a state. An operator who performs the operation of locking the cover member 40 with respect to the duct 30 will perform this operation in the vicinity of the ceiling portion 23 that is difficult to visually recognize from the luggage compartment opening 11A by reaching out 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 of the vehicle, which is relatively easily visible on the ceiling portion 23, and thereafter, the locking hole 39A is only turned by the rotation of the cover member 40. On the other hand, the locking portion 49 can be locked.

  In the process in which the cover member 40 is locked to the duct 30, the seal member 33 is compressed between the flange portion 32 and the counter plate portion 41, and a gap between the flange portion 32 and the cover member 40 is formed. Seal (see FIG. 6). Then, the outer peripheral edge portion 53 of the filter member 50 is sandwiched between the counter plate portion 41 and the flange portion 32 with the seal member 33 interposed therebetween. Then, due to the elastic force of the seal member 33, the outer peripheral edge 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 that overlaps the latching portion 43 of the cover member 40 and the latching hole 53A of the filter member 50, and the sealing member 33 causes the latching portion 43 and the latching hole to be overlapped. 53A is blocked.

  In the state where the cover member 40 is locked to the duct 30, as shown in FIG. 6, the filter member 50 is sealed around the filtration part 51 by the seal member 33, and the filtration part 51 is in the intake port 31. , The air inlet 31 is closed so as to allow ventilation. Since the filtering part 51 has a fold-like shape, the contact area with the air that passes through the vent hole 40A and flows into the intake port 31 is increased, for example, compared to a case where the filtering part 51 has a planar shape. The filtration efficiency is good.

  Then, as shown in FIG. 2, the cover member 40 is configured to cover the rim 24 </ b> A of the communication port 24 from the cargo compartment 11 side while being locked to the duct 30. Further, the cover member 40 is disposed on the ceiling portion 23 of the luggage compartment 11. Thus, 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 latching portion 49 of the cover member 40 is elastically deformed from the luggage compartment 11 side, so that the hook portion 49A and the latching hole 39A are hooked on the edge of the hole. remove. Then, the cover member 40 is rotated toward the cargo compartment 11 side (the vehicle lower side) with the portion located in the fitting hole 37A in the fitting portion 47 as an axis, and is pulled out from the locking hole 39A of the locking portion 49. . Thereafter, the fitting portion 47 is pulled out from the fitting hole 37A to the rear of the vehicle, and the locking state of the cover member 40 with respect to the duct 30 is released. At this time, the filter member 50 is held by the cover member 40 and is removed from the intake port 31 along with the cover member 40. 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 manner in which the new filter member 50 is attached to the intake port 31 is the same as that described above, and the description thereof is omitted. Thus, the replacement of the filter member 50 is completed.

  Then, the effect of this embodiment is demonstrated. According to the present embodiment, the filter member 50 is attached to the intake port 31 while the outer peripheral edge 53 is sandwiched between the cover member 40 and the flange portion 32, so that the cover member 40 is attached to the duct 30 on the cargo compartment 11 side. By disengaging from the filter member 50, the filter member 50 can be easily replaced. Furthermore, since the flange portion 32 is provided in the duct 30 and the outer peripheral edge portion 53 of the filter member 50 is sandwiched between the flange member 32 and the cover member 40 locked to the duct 30, 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. For this reason, the situation where air that does not pass through the filter member 50 from the gap formed between the filter member 50 and the intake port 31 flows into the duct 30 can be suppressed, and clean air can flow into the duct 30. Can do.

  If the duct 30 does not have the flange portion 32, for example, a configuration in which a frame-like member surrounding the intake port 31 is set in the luggage compartment 11 is conceivable. Then, the cover member 40 is locked to the frame-shaped member, and the filter member 50 is disposed 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 configured). It is conceivable to have a structure in which the seal member 33 is arranged between the wall and the end surface of the wall portion. However, in such a structure, the cover member 40 is not locked to the duct 30 and a frame-like member or the like is interposed between the cover 30 and the seal 30 due to an error in arrangement of these members. It is difficult to ensure the sealing property between the cover member 40 and the duct 30 by the member 33. Further, the filter member 50 is arranged without the seal member 33 interposed between the frame-shaped member and the cover member 40, and the filter member 50 is separated from the filter member 50 by a dimensional error or deformation of the frame-shaped member and the cover member 40. There is a possibility that air that does not pass through the filter member 50 flows into the duct 30 due to a gap between the frame member and the frame member. That is, in the structure in which the duct 30 does not have the flange portion 32 and the frame member is set in the cargo compartment 11, the low robustness related to the sealing performance becomes a problem. On the other hand, in the present embodiment, the flange portion 32 is provided in the duct 30 and the cover member 40 is locked to the duct 30, so that the number of parts related to the frame-like member can be reduced and the sealing performance is achieved. This can contribute to the improvement of robustness. Furthermore, it is not necessary to increase the size of the sealing member 33 in order to ensure such robustness, and the size of the sealing member 33 can be set as appropriate according to the dimension between the flange portion 32 and the cover member 40. Thus, the seal member 33 can be reduced in size.

  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 can fill the gap between the outer peripheral edge portion 53 and the flange portion 32, and the filter member 50 can be securely held by the flange portion 32 by the elastic force of the seal member 33. As a result, it is possible to suppress a situation in which air that does not pass through the filter member 50 flows into the duct 30 from the gap between the cover member 40 and the flange portion 32 or an unintentionally generated gap due to the displacement of the filter member 50. Can do.

  Further, in the present embodiment, the communication port 24 is formed in the ceiling portion 23 that is a planar area, and the rim 24A of the communication port 24 is placed in the 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 | deviates to the surface direction of the ceiling part 23, the structure which the cover member 40 covers 24 A of rims of the communication port 24 is maintainable. For this reason, it is possible to suppress a situation in which the edge 24A of the communication port 24 is exposed to the luggage compartment 11 due to an arrangement error of the duct 30 and the design properties of the cargo compartment 11 are impaired.

  In the present embodiment, the cover member 40 is disposed 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 near the ceiling portion 23 of the cargo compartment 11 by reaching out from the cargo compartment opening 11A. It is necessary and workability is bad. On the other hand, according to this embodiment, the filter member 50 is attached to and detached from the cover member 40 at hand, and the cover member 40 is disposed on the ceiling portion 23 of the luggage compartment 11, so 50 can be attached, and the workability of exchanging the filter member 50 is excellent. Further, in this embodiment, since the filter member 50 is attached to the air inlet 31 that opens to the ceiling portion 23, an external force is unlikely to act unintentionally around the air inlet 31 due to contact of a passenger or a load. The necessity of receiving such an external force with the above-mentioned frame-shaped member is scarce, and the frame-shaped member can be suitably abolished.
