Description

[Technical field]

[0001] The present invention relates to an air guide structure for a vehicle. [Background technology]

[0002] Conventionally, there has been known an air guide structure for a vehicle that has a guide plate extending from the side of the radiator toward the front of the vehicle in order to guide the airflow introduced into the compartment through a grill or the like at the front of the vehicle body to the radiator (for example, Patent Document 1).

[0003] In the vehicle air guide structure of Patent Document 1, an opening through which a pipe passes is provided in the flat portion of the guide plate, and a seal is provided to cover the gap between the edge of the opening and the pipe. This structure prevents the deterioration of the air-cooling performance of the radiator due to air leakage from the gap. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-290517 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the structure of Patent Document 1, the seal portion and the piping are displaced relative to each other due to vehicle body vibration, etc., and the relative displacement causes the seal portion and the piping to slide against each other, which may result in wear or damage to at least one of the seal portion and the piping. In such a case, in order to prevent wear or damage due to the relative displacement, it is necessary to carefully select and set the materials, shapes, structures, etc. of the seal portion and the piping, which may result in an increase in the effort and cost required for designing and manufacturing the air guide structure for a vehicle.

[0006] Therefore, one of the objects of the present invention is to provide an improved air guide structure for a vehicle, which can, for example, increase reliability and reduce the effort and cost of design and manufacturing. [Means for solving the problem]

[0007] The air guide structure for a vehicle of the present invention is, for example, an air guide structure for a vehicle that includes a guide plate extending from a side or lateral side of a heat exchanger toward the front of the vehicle and having an opening through which a piping connected to the heat exchanger passes, and a cover that covers a gap between the edge of the opening and the piping, wherein the cover has a first portion fixed to a peripheral portion of the opening, a second portion fixed to the piping, and a deformation portion at least partially interposed between the first portion and the second portion and capable of deforming in response to relative displacement between the guide plate and the piping.

[0008] In addition, the vehicle air guide structure of the present invention is, for example, an air guide structure for a vehicle that includes a guide plate extending from a side or lateral side of a heat exchanger toward the front of the vehicle and having an opening through which a piping connected to the heat exchanger passes, and a cover that covers a gap between the edge of the opening and the piping, wherein the cover has a first portion fixed to the peripheral portion of the opening, a second portion extending circumferentially along the outer periphery of the piping and partially surrounding the piping, and extending in the axial direction of the piping along the outer periphery over a predetermined distance, and a deformation portion at least partially interposed between the first portion and the second portion and capable of deforming in response to relative displacement between the guide plate and the piping.

[0009] In the vehicle air guide structure, a thickness of the second portion in a radial direction of the pipe may be greater than a thickness of the deformed portion.

[0010] In the vehicle air guide structure, the deformation portion may have at least one curved portion.

[0011] In the vehicle air guidance structure, the deformation portion and the second portion may be at least partially misaligned in an axial direction of the pipe.

[0012] In the vehicle air guide structure, the opening may be a notch provided in an edge of the guide plate, and the cover may be provided with a slit extending from the piping and opening to the outside of the notch.

[0013] In the vehicle air guide structure, the cover may have a third portion that is located on an open side of the cutout with respect to the deformation portion and that is thicker than the deformation portion.

[0014] In the vehicle air guidance structure, the third portion may extend from the first portion toward the slit, and the third portion may have a narrow portion whose width in the extension direction of the slit is narrower than the width at a position farther from the slit.

[0015] In the vehicle air guidance structure, the second portion may have a pair of expansion portions arranged to sandwich the slit at the boundary with the deformed portion, and extending in directions away from each other circumferentially of the piping as they proceed radially outward of the piping. Effect of the Invention

[0016] According to the present invention, it is possible to obtain an improved air guide structure for a vehicle, which can, for example, increase reliability and reduce the effort and cost of design and manufacturing. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Exemplary embodiments of the present invention are disclosed below. The configurations of the embodiments shown below, and the actions and results (effects) brought about by the configurations are merely examples. The present invention can be realized by configurations other than those disclosed in the following embodiments. According to the present invention, it is possible to obtain at least one of the various effects (including derivative effects) obtained by the configurations.

[0019] The following embodiments have the same configuration. According to the following embodiments, similar actions and effects based on the similar configuration can be obtained. In the following, the same components are given the same reference numerals, and duplicated descriptions are omitted.

[0020] In each figure, the X direction is represented by an arrow X, the Y direction is represented by an arrow Y, and the Z direction is represented by an arrow Z. The X direction, Y direction, and Z direction intersect with each other and are perpendicular to each other. The X direction indicates the front in the longitudinal direction of the vehicle, the Y direction indicates the left in the width direction of the vehicle when facing the front of the vehicle, and the Z direction indicates the upper side of the vehicle.

[0021] In this specification, ordinal numbers are given for the sake of convenience to distinguish between parts and the like, and do not indicate priority or order.

[0022] [First embodiment] Fig. 1 is a perspective view of a vehicle air guide structure 10 provided in a vehicle compartment 1. As shown in Fig. 1, the vehicle air guide structure 10 of the embodiment guides airflow introduced into the compartment 1 through an opening of a grille 2 provided in the front part of the vehicle, etc., to heat exchangers 21, 22 (20).

[0023] The heat exchangers 21, 22 (20) extend in the vehicle vertical direction and vehicle width direction, intersecting the vehicle longitudinal direction, and are arranged with a gap between them in the vehicle longitudinal direction. Each heat exchanger 20 is provided with a refrigerant pipe through which the refrigerant flows, an air flow path through which the air flows from the front to the rear of the heat exchanger 20, and a heat transfer member (all not shown) that transfers heat between the refrigerant and the air flow. In each heat exchanger 20, heat exchange is performed between the refrigerant flowing in the refrigerant pipe and the air flow flowing in the air flow path, thereby cooling the refrigerant. The heat exchanger 20 is, for example, a radiator of a cooling device that cools a cooling liquid as a refrigerant, or a condenser of an air conditioning device that cools a refrigerant gas as a refrigerant.

[0024] The vehicle air guide structure 10 includes two guide plates 11 and two covers 12.

[0025] The guide plates 11 extend toward the front of the vehicle from the left and right side portions of the heat exchanger 20 or from the sides spaced apart from the left and right side portions with a gap therebetween. Each of the guide plates 11 also extends toward the upper part of the vehicle and has a plate-like shape. The two guide plates 11 are spaced apart from each other in the vehicle width direction, and the space between these two guide plates 11 forms a passage for the airflow that is introduced into the compartment 1 and flows toward the heat exchanger 20.

[0026] Some of the multiple refrigerant pipes 23 connected to the heat exchanger 20 pass through an opening 11a provided in the guide plate 11 in the vehicle width direction. In the present embodiment, as an example, two pipes 23 connected to the front heat exchanger 21 of the two heat exchangers 20 each pass through the opening 11a.

[0027] 2 is a side view of a portion of the vehicle air guide structure 10, illustrating the guide plate 11 and cover 12 located on the right side out of the guide plates 11 and covers 12 located on the left and right sides. The guide plate 11 and cover 12 located on the left side also have a structure similar to that shown in FIG.

[0028] 2, the guide plate 11 is provided with an opening 11a through which the piping 23 passes. The opening 11a is a cutout formed in a front edge 11b, which is an end edge of the guide plate 11, and is recessed toward the rear of the vehicle and open toward the front of the vehicle.

[0029] The cover 12 covers the gap between the outer periphery 23a of the pipe 23 and the edge 11a1 of the opening 11a, and suppresses airflow from leaking from the gap.

[0030] The cover 12 has a first portion 12a, a second portion 12b, a third portion 12c, and a deformation portion 12d. The first portion 12a is fixed to a peripheral portion 11a2 of the opening 11a. The second portion 12b partially surrounds the piping 23. The deformation portion 12d is at least partially interposed between the first portion 12a and the second portion 12b. The third portion 12c is located on the open side of the opening 11a as a notch relative to the deformation portion 12d, in other words, toward the front of the vehicle.

[0031] The cover 12 is made of a synthetic resin material such as polypropylene or a thermoplastic elastomer, and the first portion 12a, the second portion 12b, the third portion 12c, and the deformation portion 12d are integrally molded from the synthetic resin material.

[0032] The first portion 12a has a plate-like shape extending in a substantially U-shape with a substantially constant thickness along the edge 11a1 of the opening 11a. The first portion 12a is provided with a through hole 12a1 through which a fastener (not shown) such as a screw passes. In this case, the first portion 12a is fixed to the guide plate 11 by being sandwiched between the guide plate 11 and a head (not shown) of a fastener that passes through the through hole 12a1 and is fixed to the guide plate 11.

[0033] The second portion 12b extends in a circumferential direction along the outer periphery 23a of the pipe 23, for example in an arc shape, and partially surrounds the pipe 23. As shown in Fig. 2, the second portion 12b has a generally C-shaped appearance that is open toward the front of the vehicle when viewed in the axial direction of the pipe 23, and surrounds most of the pipe 23 except for a front portion of the outer periphery 23a, specifically about 90% of the pipe 23. In the following description, the axial direction refers to the axial direction of the central axis C of the pipe 23, the radial direction refers to the radial direction of the central axis C, and the circumferential direction refers to the circumferential direction of the central axis C.

[0034] The second portion 12b surrounds the outer periphery 23a of the pipe 23 in a state in which it elastically expands in the radial direction. That is, in the attached state, the second portion 12b elastically presses the outer periphery 23a of the pipe 23 inward in the radial direction. In this manner, the second portion 12b and the pipe 23 are elastically fitted together. The second portion 12b and the pipe 23 are configured so that they are maintained in a relatively fixed state without being displaced from each other in the axial, circumferential, and radial directions due to, for example, a difference in load acting on the second portion 12b and the pipe 23 while the vehicle is traveling.

[0035] Fig. 3 is a cross-sectional view of the cover 12 taken along line III-III in Fig. 2. As shown in Fig. 3, the second portion 12b extends along the outer periphery 23a of the pipe 23 in the axial direction over a predetermined section, i.e., a predetermined length.

[0036] The deformation portion 12d has a plate-like or film-like shape and spreads outward in the radial direction from the second portion 12b. The deformation portion 12d has a bellows-like shape in which concentric peaks 12d1 and valleys 12d2 alternately appear as they move outward in the radial direction. The thickness td of the deformation portion 12d is thinner than the thickness ta of the first portion 12a in the thickness direction (Y direction) of the guide plate 11, and thinner than the thickness tb of the second portion 12b in the radial direction. With this configuration, the deformation portion 12d is more easily deformed than the first portion 12a and the second portion 12b, and deforms in response to the relative displacement between the guide plate 11 and the piping 23. The deformation portion 12d may also be referred to as an easily deformable portion. The peaks 12d1 and valleys 12d2 are examples of curved portions and may also be referred to as bent portions. In this embodiment, the deformation portion 12d has a plurality of curved portions.

[0037] In other words, the thickness tb of the second portion 12b in the radial direction is greater than the thickness td of the deformable portion 12d. With this configuration, when a relative displacement occurs between the guide plate 11 and the pipe 23, the second portion 12b is less likely to deform than the deformable portion 12d, and is more likely to remain fixed relative to the pipe 23.

[0038] As shown in FIG. 2, the cover 12 has two third portions 12c spaced apart from each other in the vehicle up-down direction. The upper third portion 12c of the two third portions 12c extends downward from the upper portion of the first portion 12a. The lower third portion 12c of the two third portions 12c extends upward from the lower portion of the first portion 12a. Here, the third portion 12c has a plate-like shape, and the thickness (not shown) of the third portion 12c in the thickness direction (Y direction) of the guide plate 11 is substantially the same as the thickness ta of the first portion 12a in the thickness direction of the guide plate 11. As described above, the thickness td of the deformation portion 12d is thinner than the thickness ta of the first portion 12a, in other words, the thickness ta of the first portion 12a is thicker than the thickness td of the deformation portion 12d. Therefore, the thickness of the third portion 12c is thicker than the thickness td of the deformation portion 12d.

[0039] Also, the cover 12 is provided with a slit S. The slit S extends substantially along the X direction between the piping 23 and the outside of the opening 11a, which is a notch, i.e., the front of the vehicle, through the second portion 12b, the deformation portion 12d, and the third portion 12c, and is open to the front of the vehicle. The X direction is an example of the extension direction of the slit S. It can also be said that the slit S extends in the radial direction. Here, the width of the slit S is narrower than the diameter of the piping 23. In this way, the narrowing of the width of the slit S suppresses the leakage of the airflow from the slit S. Also, the wall portion 12b1 located on the opening side of the slit S in the second portion 12b suppresses the piping 23 housed in the second portion 12b from moving toward the front of the vehicle, which is the opening direction of the slit S, relative to the second portion 12b and coming off the second portion 12b.

[0040] When piping 23 and cover 12 are integrated, piping 23 is relatively inserted into slit S from opening 11a which is a cutout and the open side of slit S, in other words, from the opposite side of slit S to second portion 12b, and moves relatively inside slit S toward second portion 12b, and is set in said second portion 12b. When piping 23 moves relatively inside slit S, cover 12 is elastically deformed, and the width of slit S temporarily elastically expands at least in the portion where piping 23 is located.

[0041] The pipe 23 and the cover 12 may be integrated with the cover 12 attached to the guide plate 11 in advance, or may be integrated before the cover 12 is attached to the guide plate 11. In the latter case, the cover 12 may be fixed to the guide plate 11 while being temporarily supported by the pipe 23, and the position of the second portion 12b relative to the pipe 23 may be adjusted or fixed when or after the first portion 12a is fixed to the guide plate 11.

[0042] As shown in FIG. 2, the two third regions 12c are arranged to sandwich the slit S from above and below, and each extends from the first region 12a toward the slit S. Here, in each of the third regions 12c, the width W3 of the third region 12c in the X direction, i.e., in the extension direction of the slit S, narrows as it moves away from the first region 12a, in other words, as it approaches the slit S. That is, the third region 12c has a so-called tapered shape in which the width W3 in the X direction gradually narrows as it moves from a base portion adjacent to the first region 12a to a tip portion adjacent to the slit S. In this way, the third region 12c has a narrow portion 12c1 at its tip portion, whose width W31 (W3) in the X direction is narrower than the width W32 (W3) of the base portion of the third region 12c. The width W32 is the width in the X direction of the third region 12c at a position farther from the slit S than the narrow portion 12c1.

[0043] FIG. 4 is a perspective view of the cover 12. As shown in FIG. 4 and FIG. 2, the second portion 12b is provided with a pair of expanding portions 12b2 at the boundary between the second portion 12b and the deformation portion 12d (slit S). The pair of expanding portions 12b2 are arranged to sandwich the slit S in the circumferential direction, and extend from the second portion 12b in a direction away from each other in the circumferential direction as they move radially outward. Therefore, the pipe 23 moving relatively from the slit S toward the second portion 12b in the circumferential inward direction (D1 direction in FIGS. 2 and 4) elastically expands the pair of expanding portions 12b2 and thus the second portion 12b in the circumferential direction when passing between the pair of expanding portions 12b2. This allows the pipe 23 to move relatively more smoothly. After the piping 23 passes between the pair of expansion portions 12b2 and is accommodated within the second portion 12b, the pair of expansion portions 12b2 and the second portion 12b return to their pre-expansion state, and the wall portion 12b1 of the second portion 12b prevents the piping 23 from escaping from the second portion 12b, in other words, the second portion 12b embraces the piping 23.

[0044] As described above, in this embodiment, the cover 12 has the first portion 12a, the second portion 12b, and the deformable portion 12d, at least a portion of which is located between the first portion 12a and the second portion 12b. The first portion 12a is fixed to the guide plate 11, and the second portion 12b is fixed to the piping 23. The deformable portion 12d deforms in response to the relative displacement between the guide plate 11 and the piping 23.

[0045] In this embodiment, the second portion 12b extends in the circumferential direction along the outer periphery 23a of the pipe 23, partially surrounds the pipe 23, and extends over a predetermined section in the axial direction along the outer periphery 23a.

[0046] According to such a configuration, it is possible to suppress the relative displacement between the second portion 12b and the pipe 23, and therefore it is possible to suppress wear and damage caused by the relative displacement to at least one of the second portion 12b and the pipe 23. As a result, for example, it is possible to obtain effects such as further improving the reliability of the vehicle air guide structure 10 and reducing the design effort since it is not necessary to consider wear and damage between the cover 12 and the pipe 23.

[0047] In the present embodiment, the second portion 12b is elastically fitted to the pipe 23. With such a configuration, for example, a structure capable of suppressing relative displacement between the second portion 12b and the pipe 23 can be obtained with a relatively simple configuration, and the effect is that the effort and cost required for manufacturing the highly reliable air guide structure 10 for a vehicle can be further reduced.

[0048] In the present embodiment, the thickness tb of the second portion 12b in the radial direction is greater than the thickness td of the deformation portion 12d. With this configuration, for example, the second portion 12b is less likely to deform than the deformation portion 12d, and the state in which the relative displacement between the second portion 12b and the pipe 23 is suppressed is easily maintained, which in turn makes it easier to further improve the reliability of the vehicle air guide structure 10.

[0049] In this embodiment, the deformation portion 12d has a peak portion 12d1 and a valley portion 12d2 (curved portion).

[0050] In this embodiment, the deformation portion 12d has a bellows shape.

[0051] According to such a configuration, for example, the deformation portion 12d is more likely to deform at the peaks 12d1 and the valleys 12d2, and the second portion 12b is more difficult to deform than the deformation portion 12d. Therefore, it becomes easier to maintain the state in which the relative displacement between the second portion 12b and the pipe 23 is suppressed, and thus the reliability of the vehicle air guide structure 10 becomes easier to improve.

[0052] In this embodiment, the opening 11a is a notch provided in the front edge 11b (end edge) of the guide plate 11, and the cover 12 is provided with a slit S extending from the pipe 23 toward the outside of the notch. With this configuration, for example, the pipe 23 can be relatively moved along the slit S from outside the notch into the second portion 12b while elastically deforming the cover 12, and can be more easily attached to the second portion 12b.

[0053] In addition, in this embodiment, the cover 12 has a third portion 12c. The third portion 12c is located on the open side of the opening 11a as a notch with respect to the deformation portion 12d, and is thicker than the deformation portion 12d. Therefore, the third portion 12c is less likely to deform than the deformation portion 12d. If the third portion 12c did not exist, the deformation portion 12d would be deformed due to vibrations of the vehicle during travel, pressure of the airflow, etc., and the gap of the slit S would be more likely to expand, and the leakage of the airflow through the gap of the slit S would increase. In this regard, in this embodiment, the gap of the slit S is less likely to expand due to the presence of the third portion 12c, so that the leakage of the airflow through the slit S can be suppressed from increasing.

[0054] Moreover, in this embodiment, third portion 12c has narrow portion 12c1 whose width in the X direction (extension direction of slit S) is narrower than the width at a position farther from slit S. With this configuration, for example, when pipe 23 moves relatively through slit S during assembly work, third portion 12c becomes more easily deformed, and accordingly, it becomes possible to perform the assembly work more easily or more quickly.

[0055] [Second embodiment] Fig. 5 is a cross-sectional view of the cover 12A of the second embodiment at the same position as in Fig. 3. As shown in Fig. 5, this embodiment differs from the first embodiment in that the first portion 12a and the second portion 12b are offset in the axial direction. This embodiment also suppresses the relative movement between the second portion 12b and the pipe 23, so that the same effect as the first embodiment can be obtained.

[0056] [Third embodiment] FIG. 6 is a cross-sectional view of the cover 12B of the third embodiment at the same position as FIG. 3. As shown in FIG. 6, in this embodiment, the shape of the deformation portion 12d is different from that of the first and second embodiments. That is, the deformation portion 12d does not have a bellows shape, but has a three-dimensional curved shape with one curved portion 12d3. The deformation portion 12d has a rotating body shape in which a forward-convex U-shaped cross section is rotated around the central axis of the pipe 23, in other words, it has a front half of a torus shape cut by a plane intersecting the central axis, that is, a semi-torus shape protruding forward. According to this embodiment, the relative movement between the second portion 12b and the pipe 23 is suppressed, so that the same effect as the first embodiment can be obtained.

[0057] Although the embodiment of the present invention has been illustrated above, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the gist of the invention. In addition, the specifications of each configuration, shape, and the like (structure, type, direction, model, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.

[0058] For example, the pipe and the second portion may be fixed by, for example, heat welding, claw fastening, adhesive, or the like, or may be fixed via a fastener such as a clip or a hose band, or may be fixed by using several fastening means in combination. In addition, the deformation portion is not limited to the above embodiment, and may be implemented in various structures and shapes. [Explanation of symbols]
