Description

[Technical field]

[0001] The present invention relates to an air guide structure for a vehicle that guides cooling air to, for example, a heat exchanger. [Background technology]

[0002] Conventionally, vehicles have been provided with an air guide structure that guides air flowing in from an opening provided along the outer periphery of the front of the vehicle body to a heat exchanger provided inside the vehicle body, such as a radiator or an intercooler. For example, Patent Document 1 describes an air guide structure that guides air flow from an opening provided in a side grill toward a heat effector at the center side in the vehicle width direction. For example, Patent Document 2 describes an air guide structure that guides air flow from an opening provided in a front grill toward a rear heat effector.

[0003] An example of a conventional air guide structure is shown in Fig. 10. The air guide structure 50 has, for example, a lower bumper 51 which forms the lower front surface of a vehicle body, and a lower grille 52 which is disposed rearward of the lower bumper 51 and has an opening 52a. The air guide structure 50 has an air guide 53 which is disposed rearward of the opening 52a of the lower grille 52. The air guide is formed, for example, in the shape of a relatively soft plate.

[0004] A first end 54, which is the rear end of the air guide 53, is connected to, for example, a bracket supporting a radiator and fixed to the vehicle body. A second end 55, which is the front end of the air guide 53, is in surface contact with the rear surface 51a of the lower bumper 51 or the rear surface 52b of the lower grill 52 from the rear. This fills the gap between the second end 55 of the air guide 53 and the rear surface 51a of the lower bumper 51 or the rear surface 52b of the lower grill 52, and maintains a sealed state. In addition, by not fixing the second end 55 of the air guide 53, damage to the air guide can be suppressed even if the lower bumper 51 or the lower grill 52 is deformed. Therefore, a structure in which air is guided from the opening 52a of the lower grill 52 to the heat exchanger can be maintained.

[0005] However, for example, when the vehicle is running, a fast wind enters the air guide structure 50 through the opening 52a of the lower grill 52. At this time, the air guide 53 is pushed downwind by the wind pressure with the first end 54 as a fulcrum. Therefore, as shown by the imaginary line in the figure, a gap is generated between the second end 55 of the air guide 53 and the rear surface 51a of the lower bumper 51 or the rear surface 52b of the lower grill 52. This deteriorates the aerodynamic performance. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2015-110399 A [Patent Document 2] JP 2012-144125 A Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, there is a need for an air guide structure for a vehicle that can maintain the sealing properties of the air guide that guides the air and suppress a decrease in aerodynamic performance. [Means for solving the problem]

[0008] According to one feature of the present disclosure, the vehicle air guide structure includes a bumper. The vehicle air guide structure includes a grill disposed rearward of the bumper and having an opening. The vehicle air guide structure includes an air guide disposed rearward of the opening of the grill. A first end of the air guide is fixed to the vehicle body. A second end of the air guide is a free end and contacts the grill or the bumper. The grill or the bumper is provided with a restricting portion that stands on a side away from the opening that is the leeward side of the second end and restricts movement of the second end to the leeward side.

[0009] Therefore, when the air guide receives wind pressure from the air entering through the opening of the grill, the second end of the air guide tends to move toward the downwind side (left-right direction) along the rear surface of the grill or bumper. Alternatively, the second end of the air guide tends to move toward the downwind side, away from the rear of the grill or bumper. However, the second end of the air guide is restricted from moving left-right and toward the rear downwind side by the restricting portion. This makes it possible to prevent gaps from occurring between the second end of the air guide and the rear surface of the grill or bumper, and to maintain sealing performance. This makes it possible to smoothly guide air from the opening of the grill through the air guide to a heat exchanger, etc., and to prevent a decrease in aerodynamic performance.

[0010] According to another feature of the present disclosure, the restricting portion is a single member with the grille or bumper. Therefore, the restricting portion can be provided without increasing the number of parts. This makes it possible to suppress an increase in material costs and thus to suppress the manufacturing costs of the vehicle air guide structure. Also, it is possible to suppress an increase in the number of steps required for assembling the air guide structure. This makes it possible to improve the ease of assembly of the vehicle air guide structure.

[0011] According to another feature of the present disclosure, the second end of the air guide is aligned along the rear surface of the grille or bumper, and the tip of the second end faces the restricting portion. Therefore, when the air guide is subjected to wind pressure, the tip of the second end is pressed toward the restricting portion and follows the rear surface of the grille or bumper. Therefore, the tip of the second end can be kept sealed against the restricting portion and the rear surface of the grille or bumper. This can further suppress the deterioration of aerodynamic performance. [Brief description of the drawings]

[0013] A first embodiment of the present disclosure will be described in detail below with reference to Figures 1 to 5. The same reference numbers in the description refer to the same elements having the same functions, although duplicated descriptions will not be given. Figure 1 is a front view of a vehicle 1 equipped with a vehicle air guide structure according to this embodiment. Hereinafter, the front-rear, up-down, left-right directions in the drawings and in the following description are defined as the front-rear, up-down, left-right directions of the vehicle 1.

[0014] As shown in Fig. 1, a lower bumper 11 constituting a front bumper is provided on the front side of a vehicle body 2 of a vehicle 1. The lower bumper 11 is fixed to a lower part of the front end of the vehicle body 2 by screws or the like (not shown). An upper bumper 21 constituting a front bumper is provided on the front side of the vehicle body 2 above the lower bumper 11. The upper bumper 21 is fixed to approximately the center of the front end of the vehicle body 2 by screws or the like (not shown).

[0015] As shown in Figs. 1 and 3, a lower grille 12 having a plurality of openings 12a penetrating in the front-rear direction is attached to the center of the lower bumper 11 in the left-right direction. The lower grille 12 is provided in an elongated shape in the left-right direction of the vehicle 1. The plurality of openings 12a are divided by a plurality of ribs 12b extending linearly in the up-down direction or the left-right direction. A radiator (heat exchanger) for an internal combustion engine or an electric device, for example, is provided behind the lower grille 12. The radiator is held by a bracket 3 fixed to the vehicle body 2. The vehicle 1 has an air guide structure 10 that guides air entering through the openings 12a of the lower grille 12 toward the radiator held by the bracket 3. The air guide structure 10 includes the lower bumper 11 and the lower grille 12.

[0016] As shown in FIG. 1, an upper grille 22 having a plurality of openings 22a penetrating in the front-rear direction is attached to the center of the upper bumper 21 in the left-right direction. The upper grille 22 is provided in a long shape in the left-right direction of the vehicle 1. The plurality of openings 22a are divided by a plurality of ribs 22b extending linearly in the up-down direction or the left-right direction. A radiator held by a bracket 3 (see FIG. 3) is disposed behind the upper grille 22. The vehicle 1 has an air guide structure 20 that guides air entering through the openings 22a of the upper grille 22 toward the radiator. The air guide structure 20 includes the upper bumper 21 and the upper grille 22. The air guide structure 10 on the lower grille 12 side will be described in detail below, but a mechanism similar to the air guide structure 10 may be applied to the air guide structure 20 on the upper grille 22 side.

[0017] As shown in Figs. 3 and 5, the lower grille 12 has left and right side portions 12d extending from the center portion where the opening 12a is provided to the left or right downwind side. The rear surface 12c of the lower grille 12 is formed in a substantially flat shape at the left and right side portions 12d. The rear surface 12c extends generally in the left-right direction and is slightly inclined backward toward the downwind side of the opening 12a. The pair of left and right side portions 12d are each provided with a bumper engagement portion 12e that engages with the engaged portion 11b of the lower bumper 11. The bumper engagement portion 12e is provided in an area between the opening 12a and the substantially flat rear surface 12c in the left-right direction. The engaged portion 11b is bent backward in an L-shape at the tip of the lower bumper 11. The bumper engagement portion 12e is formed in a substantially U-shape that opens forward to allow the engaged portion 11b of the lower bumper 11 to enter. The rear surface 11a of the lower bumper 11 extends generally flat in front of the rear surface 12c of the lower grille 12, following the rear surface 12c. The rear surface 11a extends generally in the left-right direction, and is slightly inclined rearward toward the leeward side of the opening 12a.

[0018] As shown in Figs. 2 to 4 and 6 to 7, the air guide structure 10 has an air guide 13 disposed behind the lower grill 12. The air guide 13 includes a right air guide 13a provided behind the right part of the lower grill 12 and a left air guide 13b provided behind the left part of the lower grill 12. The right air guide 13a and the left air guide 13b are provided symmetrically to each other. The right air guide 13a and the left air guide 13b are each connected to and fixed to a bracket 3. The air guide 13 has a first end 14 fixed to the bracket 3 on the center side of the vehicle 1. The first end 14 is fastened and fixed to the bracket 3 by, for example, a screw (not shown) or the like.

[0019] As shown in Figs. 2-4, 6-7, the wind guide 13 has a second end 15 that contacts the rear surface 12c of the lower grille 12 on the opposite side to the first end 14. The wind guide 13 extends from the first end 14 to the second end 15 generally toward the left and right outside of the vehicle 1, and also toward the front. The wind that enters through the opening 12a of the lower grille 12 is guided by the wind guide 13 from the front second end 15 side toward the rear first end 14 side. The wind guide 13 has a connecting portion 13c that covers the wind guide path from above and sides between the first end 14 and the second end 15. The wind guide 13 is made of a relatively soft plate-like member. The first end 14, the connecting portion 13c, and the second end 15 are connected to each other in a substantially U-shaped manner.

[0020] As shown in FIG. 3, the second end 15 is not fixed to the lower grill 12 and is in a free end state. Therefore, the air guide 13 is in a cantilever state at the first end 14. The second end 15 is movable left and right and rearward relative to the rear surface 12c of the lower grill 12. In the present disclosure, the movement of the second end 15 can be restricted by providing a restricting portion 16, which will be described later. By not fixing the second end 15 of the air guide 13 to the lower grill 12 or the lower bumper 11, damage to the air guide 13 can be suppressed in the unlikely event that the lower grill 12 or the lower bumper 11 receives an impact.

[0021] As shown in Figs. 3-4 and 6-7, the tip 15a of the second end 15 extends in a direction intersecting with other regions of the second end 15. Specifically, the tip 15a extends generally in the left-right direction so as to be generally parallel to the rear surface 12c of the lower grill 12 when it comes into contact with the rear surface 12c. The tip 15a extends toward the downwind side as viewed from the opening 12a of the lower grill 12. The tip 15a is fin-shaped and comes into surface contact with the rear surface 12c of the lower grill 12. Providing the tip 15a provides the wind guide 13 with enough strength to suppress deformation when it moves rearward due to wind pressure.

[0022] 2 and 4, the air guide structure 10 has an air guide 23 disposed behind the upper grill 22 (see FIG. 1). The air guide 23 has a first end portion on the inside in the left-right direction fixed to the bracket 3, and a second end portion on the outside not fixed to the upper grill 22 but in a free end state. The air guide 23 may be provided with a structure similar to that of the air guide 13, for example, a structure of the tip 15a of the second end portion 15.

[0023] 3 to 7, restricting portions 16 are provided at the leeward tips of the left and right side portions 12d of the lower grille 12, standing rearward from the rear surface 12c. The restricting portions 16 have base portions 16a connected to the left and right side portions 12d. The restricting portions 16 are bent rearward at a substantially right angle in an L-shape from the base portions 16a to the left and right side portions 12d extending in the left-right direction. The tips 16b of the restricting portions 16 are located rearward of the base portions 16a of the restricting portions 16 and slightly inward of the vehicle 1 in the left-right direction.

[0024] As shown in FIG. 3, the tip 15a of the second end 15 of the air guide 13 comes into contact with the restricting portion 16 in the left-right direction. As viewed from the opening 12a of the lower grille 12, the tip 15a of the second end 15 is located on the windward side, and the restricting portion 16 is located on the leeward side. The tip 15a of the second end 15 comes into contact with the restricting portion 16, so that the tip 15a is prevented from moving further downwind than the restricting portion 16 in the left-right direction. The tip 15a of the second end 15 can move backward toward the leeward side with the first end 14 fixed to the bracket as a fulcrum. However, the restricting portion 16 is disposed in a region where the tip 15a can move. Therefore, the tip 15a of the second end 15 is prevented from moving backward as well as left-right.

[0025] As shown in FIG. 3, for example, when air enters through the opening 12a of the lower grill 12, the second end 15 tends to move left-right downwind and rearward. However, the movement of the second end 15 is restricted by the restricting portion 16. Moreover, the tip 15a of the second end 15 is provided in a fin shape following the rear surface 12c of the lower grill 12. Therefore, the tip 15a of the second end 15 is restricted from moving while preventing a gap from being generated between the restricting portion 16 and the rear surface 12c of the lower grill 12. This makes it possible to maintain a seal between the second end 15 and the rear surface 12c of the lower grill 12. Therefore, it is possible to guide the air from the air guide 13 to the radiator at the rear while suppressing a decrease in aerodynamic performance.

[0026] As described above, the air guide structure 10 for a vehicle has a lower bumper 11 as shown in Fig. 3. The air guide structure 10 has a lower grille 12 disposed rearward of the lower bumper 11 and having an opening 12a. The air guide structure 10 has an air guide 13 disposed rearward of the opening 12a of the lower grille 12. A first end 14 of the air guide 13 is fixed to the vehicle body 2. A second end 15 of the air guide 13 is a free end and contacts the lower grille 12. The lower grille 12 is provided with a restricting portion 16 that stands on the side away from the opening 12a, which is the leeward side of the second end 15, and restricts movement of the second end 15 to the leeward side.

[0027] Therefore, when the air guide 13 receives wind pressure from the air entering through the opening 12a of the lower grill 12, the second end 15 of the air guide 13 tends to move toward the downwind side (left-right direction) along the rear surface 12c of the lower grill 12. Alternatively, the second end 15 of the air guide 13 tends to move toward the downwind side, away from the rear of the lower grill 12. However, the second end 15 of the air guide 13 is restricted from moving in the left-right direction and toward the rear downwind side by the restricting portion 16. This makes it possible to prevent a gap from being generated between the second end 15 of the air guide 13 and the rear surface 12c of the lower grill 12, and to maintain sealing performance. This makes it possible to smoothly guide air from the opening 12a of the lower grill 12 through the air guide 13 to a heat exchanger or the like, and to prevent a decrease in aerodynamic performance.

[0028] As shown in Figures 3 and 5, the restricting portion 16 is one member with the lower grille 12. Therefore, the restricting portion 16 can be provided without increasing the number of parts. This makes it possible to suppress an increase in material costs and therefore the manufacturing costs of the air guide structure 10. Also, it is possible to suppress an increase in the number of steps for assembling the air guide structure 10. This makes it possible to improve the ease of assembling the air guide structure 10.

[0029] 3, the second end 15 of the air guide 13 is aligned along the rear surface 12c of the lower grill 12, and the tip 15a of the second end 15 faces the restricting portion 16. Therefore, when the air guide 13 is subjected to wind pressure, the tip 15a of the second end 15 is pressed toward the restricting portion 16 on the leeward side, and follows the rear surface 12c of the lower grill 12. Therefore, the tip 15a of the second end 15 can be kept sealed against the restricting portion 16 and the rear surface 12c of the lower grill 12. This can further suppress the deterioration of aerodynamic performance.

[0030] Next, a second embodiment of the present disclosure will be described with reference to Fig. 8. The air guide structure 30 of the second embodiment has a lower bumper 31, a lower grille 32, and a restricting portion 33, instead of the lower bumper 11, the lower grille 12, and the restricting portion 16 of the air guide structure 10 shown in Fig. 3. In the following description, only the points different from the first embodiment will be described in detail.

[0031] As shown in FIG. 8, a lower grille 32 having a plurality of openings 32a penetrating in the front-rear direction is attached to the center of the lower bumper 31. The lower grille 32 is provided in a long shape in the left-right direction of the vehicle 1. The lower grille 32 has left and right side portions 32c extending from the center portion where the openings 32a are provided to the left or right downwind side. The rear surface 32b of the lower grille 32 is formed in a substantially flat shape in the left and right side portions 32c. The rear surface 32b extends generally in the left-right direction and is slightly inclined backward toward the downwind side of the openings 32a. The lower grille 32 engages with the tip of the lower bumper 31 between the left and right side portions 32c and the openings 32a in the left-right direction. As a result, the lower grille 32 is held by the lower bumper 31. The rear surface 31a of the lower bumper 31 extends in a substantially flat shape in front of the rear surface 32b of the lower grille 32, following the rear surface 32b. The rear surface 31a extends generally in the left-right direction and is inclined slightly rearward toward the downwind side of the opening 32a.

[0032] As shown in FIG. 8, the lower bumper 31 has a restricting portion 33 that stands rearward on the rear surface 31a. The restricting portion 33 is disposed on the leeward side (left side in the figure) of the tip 15a of the second end 15 of the air guide 13. The restricting portion 33 is a convex portion 33a that is convex toward the rear on the rear surface 31a of the lower bumper 31. The convex portion 33a protrudes rearward beyond the tip 15a of the second end 15 of the air guide 13. The restricting portion 33 is a recessed portion 33b that is concave toward the rear on the front surface of the lower bumper 31. The restricting portion 33 is substantially rectangular in cross section extending in the horizontal direction. The restricting portion 33 protrudes slightly toward the inside of the vehicle 1 in the rear and left-right directions.

[0033] As shown in FIG. 8, when viewed from the opening 32a of the lower grille 32, the tip 15a of the second end 15 is located on the windward side, and the restricting portion 33 is located on the leeward side. The tip 15a of the second end 15 is restrained from moving further downwind than the restricting portion 33 in the left-right direction by contacting the restricting portion 33. The tip 15a of the second end 15 can move rearward toward the leeward side with the first end 14 fixed to the bracket as a fulcrum. However, the restricting portion 33 is disposed in an area where the tip 15a can move. Therefore, the tip 15a of the second end 15 is restrained from moving rearward as well as left-right. Moreover, the fin-shaped tip 15a follows the rear surface 31a of the lower bumper 31, so that no gap is generated between the restricting portion 33 and the rear surface 31a of the lower bumper 31, and thus the movement is restrained.

[0034] As described above, the air guide structure 30 for a vehicle has a lower bumper 31 as shown in Fig. 8. The air guide structure 30 has a lower grille 32 disposed rearward of the lower bumper 31 and having an opening 32a. The air guide structure 30 has an air guide 13 disposed rearward of the opening 32a of the lower grille 32. A first end 14 of the air guide 13 is fixed to the vehicle body 2. A second end 15 of the air guide 13 is a free end and contacts the lower bumper 31. The lower bumper 31 is provided with a restricting portion 33 that stands on the side away from the opening 32a, which is the leeward side of the second end 15, and restricts movement of the second end 15 to the leeward side.

[0035] Therefore, when the air guide 13 receives wind pressure from the air entering through the opening 32a of the lower grille 32, the second end 15 of the air guide 13 tends to move toward the downwind side (left-right direction) along the rear surface 31a of the lower bumper 31. Alternatively, the second end 15 of the air guide 13 tends to move toward the downwind side away from the rear of the lower bumper 31. However, the second end 15 of the air guide 13 is restricted from moving in the left-right direction and toward the rear downwind side by the restricting portion 33. This makes it possible to prevent a gap from being generated between the second end 15 of the air guide 13 and the rear surface 31a of the lower bumper 31, and to maintain sealing performance. This makes it possible to smoothly guide air from the opening 32a of the lower grille 32 through the air guide 13 to a heat exchanger or the like, thereby making it possible to prevent a decrease in aerodynamic performance.

[0036] As shown in Fig. 8, the restricting portion 33 is one member with the lower bumper 31. Therefore, the restricting portion 33 can be provided without increasing the number of parts. This makes it possible to suppress an increase in material costs and therefore the manufacturing costs of the air guide structure 30. Also, it is possible to suppress an increase in the number of steps for assembling the air guide structure 30. This makes it possible to improve the ease of assembling the air guide structure 30.

[0037] 8, the second end 15 of the air guide 13 is aligned along the rear surface 31a of the lower bumper 31, and the tip 15a of the second end 15 faces the restricting portion 33. Therefore, when the air guide 13 receives wind pressure, the tip 15a of the second end 15 is pressed toward the restricting portion 33 and follows the rear surface 31a of the lower bumper 31. Therefore, the tip 15a of the second end 15 can be kept sealed against the restricting portion 33 and the rear surface 31a of the lower bumper 31. This can further suppress the deterioration of aerodynamic performance.

[0038] Next, a third embodiment of the present disclosure will be described with reference to Fig. 9. An air guide structure 40 of the third embodiment has a lower grill 41 and a restriction portion 42 instead of the lower grill 12 and the restriction portion 16 of the air guide structure 10 shown in Fig. 3. In the following description, only the points different from the first embodiment will be described in detail.

[0039] As shown in FIG. 9, a lower grill 41 having a plurality of openings 41a penetrating in the front-rear direction is attached to the center of the lower bumper 11. The lower grill 41 is provided in a long shape in the left-right direction of the vehicle 1. The lower grill 41 has left and right side portions 41c extending from the center portion where the openings 41a are provided to the left or right downwind side. The rear surface 41b of the lower grill 41 is formed in a substantially flat shape in the left and right side portions 41c. The rear surface 41b extends generally in the left-right direction and is slightly inclined backward toward the downwind side of the openings 41a. The lower grill 41 engages with the lower bumper 11 between the left and right side portions 41c and the openings 41a in the left-right direction. As a result, the lower grill 41 is held by the lower bumper 11. The rear surface 11a of the lower bumper 11 extends in a substantially flat shape in front of the rear surface 41b of the lower grill 41 in accordance with the rear surface 41b.

[0040] As shown in Fig. 9, the leeward end of the left and right side portions 41c of the lower grille 41 is provided with a restricting portion 42 that stands rearward relative to the rear surface 41b. The restricting portion 42 has a base portion 42a that is connected to the left and right side portions 41c. The restricting portion 42 is bent rearward at a substantially right angle in an L-shape relative to the left and right side portions 41c that extend from the base portion 42a in the left and right directions. The restricting portion 42 has a middle portion 42b that extends slightly rearward and in the left and right directions from the base portion 42a toward the inside of the vehicle 1. The restricting portion 42 has a tip portion 42c that protrudes from the middle portion 42b toward the inside of the vehicle 1 substantially parallel to the left and right side portions 41c.

[0041] As shown in FIG. 9, when viewed from the opening 41a of the lower grill 41, the tip 15a of the second end 15 is located on the windward side, and the middle part 42b of the restricting part 42 is located on the leeward side. The tip 15a of the second end 15 enters a substantially rectangular area formed by the rear surface 41b of the lower grill 41 and the middle part 42b and tip 42c of the restricting part 42 in cooperation with each other. The tip 15a of the second end 15 is restrained from moving toward the leeward side of the restricting part 42 in the left-right direction by contacting the middle part 42b of the restricting part 42. In addition, the tip 15a of the second end 15 is restrained from moving toward the rearward leeward side by the tip 42c of the restricting part 42. Moreover, the fin-shaped tip 15a follows the rear surface 41b of the lower grill 41, so that the movement is restrained without creating a gap between the restricting part 42 and the rear surface 41b of the lower grill 41.

[0042] The air guide structures 10, 30, 40 of the above-described embodiments may be modified as appropriate. For example, the air guide destination of the air guide structures 10, 30, 40 is not limited to a radiator, but may be a heat exchanger such as an intercooler. Although the air guide structures 10, 30, 40 on the lower grill 12, 32, 41 side have been exemplified, they may also be applied to the air guide structure on the upper grill side.

[0043] The shapes of the openings 12a, 32a, 41a of the lower grills 12, 32, 41 are not limited to those exemplified and may be changed as appropriate, and the shape of the air guide 13 may be changed as appropriate accordingly. The restricting portions 16, 33, 42 that restrict the movement of the air guide 13 may be provided on either the lower bumper 11, 31 or the lower grill 12, 32, 41, or may be provided on both. The lower bumper 11, 31 and the lower grill 12, 32, 41 may be configured as a single member.

[0044] Although the air guide 13 is illustrated as being divided into two parts, left and right, it may be a single member that is long in the left-right direction. The object to which the air guide 13 is fixed is not limited to the bracket 3, and may be any internal structure of the vehicle body 2. The shapes, sizes, etc. of the restricting portions 16, 33, 42 are not limited to those illustrated, and may be appropriately changed as long as they can restrict the movement of the air guide 13. For example, the restricting portion 16 may be bent so as to form an acute angle with respect to the rear surface 12c of the lower grille 12. For example, the cross-sectional shape of the restricting portion 33 in the horizontal direction may be a substantially triangular mountain shape, etc. [Explanation of symbols]
