Description

[Technical field]

[0001] The present invention relates to an air guide structure, and more particularly to an air guide structure for guiding air to a heat exchanger mounted on a vehicle. [Background technology]

[0002] In the front of a vehicle such as a passenger car, heat exchangers such as a radiator, an evaporator and a condenser of a refrigeration cycle are disposed. In front of the heat exchanger, an introduction mechanism is provided to effectively introduce air into the heat exchanger while the vehicle is traveling.

[0003] In the cooling air introduction device described in Patent Document 1, the air inlet through which the air is introduced is divided by an upper and lower partition member in front of the heat exchanger. In this way, the cooling air introduced from each air inlet is guided to the heat exchanger without interfering with each other. In addition, the rear end of the partition member is fixed to the radiator panel, and the front end overhangs the upper part of the bumper beam. Therefore, even if the bumper beam moves backward during a minor collision, the heat exchanger will not be damaged. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2012-210894 A Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The air guide structure 12 according to the embodiment of the present invention will be described in detail below with reference to the drawings. In the following description, the front, rear, up, down, left and right directions are used, and the left and right directions refer to the left and right directions when the vehicle 10 is viewed from the front. Furthermore, in the following description, the same members are basically given the same reference numerals, and repeated description will be omitted.

[0012] FIG. 1 is a perspective view showing a front configuration of a vehicle 10 equipped with an air guide structure 12. As shown in FIG.

[0013] The air guide structure 12 guides air from the front to a heat exchanger 11 mounted on a vehicle 10 while the vehicle is traveling. The air guide structure 12 includes a substantially plate-shaped air guide 13. The air guide 13 has an upper air guide 19, a left air guide 20, and a right air guide 21.

[0014] The vehicle 10 is, for example, a passenger car, and a substantially frame-shaped radiator panel 23 is formed at the front end of the vehicle body. The air guide 13 is attached to the front side of the radiator panel 23. A heat exchanger 11 is disposed inside the radiator panel 23. When viewed from the front, the heat exchanger 11 is disposed inside the upper air guide 19, the left air guide 20, and the right air guide 21.

[0015] As will be described later, the air guide 13 has a shape that can be bent in a predetermined direction in response to an input from the front, and is configured so that when a minor collision occurs, the bent air guide 13 does not interfere with the heat exchanger 11. A specific configuration of the air guide 13 will be described later with reference to Fig. 2 etc. Here, a minor collision is, for example, a minor collision in which the front surface of the front grille 15 is lightly hit.

[0016] 2 is a perspective view showing air guide 13. As described above, air guide 13 has upper air guide 19 disposed on the upper side, left air guide 20 disposed on the left side, and right air guide 21 disposed on the right side. Upper air guide 19, left air guide 20, and right air guide 21 are made of synthetic resin plates molded into a substantially plate shape.

[0017] The upper air guide 19 has a base portion 191 that constitutes its rear portion, and a tip side portion 192 that constitutes its front portion.

[0018] The left air guide 20 has a base portion 201 that constitutes its rear portion, and a tip side portion 202 that constitutes its front portion.

[0019] The right air guide 21 has a base portion 211 that constitutes its rear portion, and a tip side portion 212 that constitutes the front portion thereof.

[0020] As described below, when a minor collision occurs at the front of the vehicle 10, the leading end side portion 192 of the upper air guide 19, the leading end side portion 202 of the left air guide 20, and the leading end side portion 212 of the right air guide 21 are bent. In this manner, it is possible to prevent excessive force from being generated, and further, it is possible to prevent damage to members on the vehicle body side.

[0021] FIG. 3A is a top view showing upper air guide 19, and FIG. 3B is a side cross-sectional view showing the front part of the vehicle where upper air guide 19 is arranged.

[0022] With reference to FIG. 3A, the upper air guide 19 has a base portion 191, a bending starting point 193, and a tip side portion 192 from the rear side.

[0023] The base material portion 191 is a generally plate-shaped portion that is elongated along the left-right direction, and is disposed in a range that does not interfere with a stroke 17 during a light collision, which will be described later with reference to FIG.

[0024] The tip side portion 192 is a generally plate-like portion that is elongated and extends in the left-right direction, is disposed in a range that is affected by the stroke 17 during a light collision, and is a portion that bends when a light collision occurs. In addition, both left-right end portions of the rear edge of the tip side portion 192 form abutment portion 197 and abutment portion 198. Abutment portion 197 is a portion of the rear edge of the tip side portion 192 that protrudes to the right beyond the right end of the base portion 191. Abutment portion 198 is a portion of the rear edge of the tip side portion 192 that protrudes to the left beyond the left end of the base portion 191.

[0025] The bending starting point 193 extends in a substantially straight line between the base material portion 191 and the tip side portion 192 in a direction substantially perpendicular to the vehicle travel direction, in this case, the left-right direction. Here, the bending starting point 193 is indicated by hatching. The bending starting point 193 is a portion where the strength of the upper air guide 19 is locally reduced, and for example, the thickness of the bending starting point 193 is made thinner than the average thickness of the base material portion 191 and the tip side portion 192. In addition, the bending starting point 193 is formed continuously from the left end to the right end of the base material portion 191. In this way, as will be described later, when a minor collision occurs, the tip side portion 192 can be bent with the bending starting point 193 as a fulcrum.

[0026] The rib 194 is a portion of the base material 191 that protrudes in the thickness direction in a wall-like shape. The rib 194 extends on the surface of the base material 191 in the left-right direction, the front-rear direction, and the inclination direction. The rib 194 may be formed on either the upper surface or the lower surface of the base material 191, or on both. By forming the rib 194, the rigidity of the base material 191 can be increased, and deformation of the base material 191 can be suppressed when a minor collision occurs.

[0027] The rib 195 is a portion of the tip side portion 192 that protrudes in the thickness direction in a wall-like shape. The rib 195 extends on the surface of the tip side portion 192 in the left-right direction, the front-rear direction, and the inclination direction. The rib 195 may be formed on either the upper surface or the lower surface of the tip side portion 192, or on both. By forming the rib 195, the bending direction of the tip side portion 192 can be restricted downward when a minor collision occurs. In addition, a rib 1951 extending in the front-rear direction is formed in the center of the tip side portion 192 in the left-right direction. As described later, the rib 1951 is a portion that restricts the bending direction of the tip side portion 192.

[0028] Here, the reinforcing effect of the rib 194 on the base portion 191 may be greater than the reinforcing effect of the rib 195 on the tip side portion 192. For example, the reinforcing effect of the rib 194 can be increased by making the thickness and height of the rib 194 greater than those of the rib 195. Furthermore, the reinforcing effect of the rib 194 can be relatively increased by forming the rib 194 more densely than the rib 195. In this way, when a light collision occurs, the deformation of the base portion 191 is suppressed, while the tip side portion 192 is allowed to bend downward, and the tip side portion 192 can be stably bent in the intended direction, and the tip side portion 192 can be prevented from interfering with the heat exchanger 11. Here, the rib 195 does not necessarily need to be formed on the tip side portion 192, and the surface of the tip side portion 192 can be made flat.

[0029] With reference to FIG. 3B, the tip side portion 192 has a shape capable of restricting the bending direction in the event of a minor collision to the heat exchanger 11 side.

[0030] Specifically, a front hood 14 and a front grille 15 are disposed at the front end of the vehicle 10. The upper air guide 19 is disposed on the rear side of the front grille 15. A base material portion 191 of the upper air guide 19 is disposed substantially horizontally. Meanwhile, a tip side portion 192 has an inclined shape that is curved downward toward the front. In this way, as will be described later, when a minor collision occurs, the tip side portion 192 can be bent downward from a bending starting point 193 as a starting point.

[0031] Moreover, the rib 1951 formed on the upper surface of the tip side portion 192 is inclined downward toward the front, similar to the tip side portion 192. This also has the effect of bending the tip side portion 192 downward when a minor collision occurs, as will be described later.

[0032] FIG. 4A is a side view of right air guide 21 as viewed from the right, and FIG. 4B is a side view of left air guide 20 as viewed from the left.

[0033] Referring to FIG. 4A, the right air guide 21 has a base portion 211 and a tip side portion 212 from the rear. A bending origin 213 indicated by hatching is formed between the base portion 211 and the tip side portion 212. The base portion 211 constitutes the rear portion of the right air guide 21 and is a portion extending from the upper end to the lower end of the right air guide 21. A rib 214 is formed on the base portion 211. The tip side portion 212 constitutes the front portion of the right air guide 21 and its upper portion protrudes forward. A rib 215 is formed on the tip side portion 212. The bending origin 213 is formed continuously from the upper end to the lower end of the right air guide 21. The bending origin 213 is a portion where the right air guide 21 is partially thinned. When a light collision occurs, the tip side portion 212 bends inward or outward starting from the bending origin 213.

[0034] Referring to FIG. 4B, the left air guide 20 has the same configuration as the right air guide 21 described above. Specifically, the left air guide 20 has a base portion 201 and a tip side portion 202 from the rear. Between the base portion 201 and the tip side portion 202, a bending starting point 203 shown by hatching is formed. The base portion 201 constitutes the rear portion of the left air guide 20 and is a portion extending from the upper end to the lower end of the left air guide 20. A rib 204 is formed on the base portion 201. The tip side portion 202 constitutes the front portion of the left air guide 20 and its upper portion protrudes forward. A rib 205 is formed on the tip side portion 202. The bending starting point 203 is formed continuously from the upper end to the lower end of the left air guide 20. The bending starting point 203 is a portion where the left air guide 20 is partially thinned. When a light collision occurs, the tip side portion 202 bends inward or outward starting from the bending starting point 203 .

[0035] 5 is a side cross-sectional view showing the front part of a vehicle when a minor collision occurs, in which stroke 17 during a minor collision is indicated by a dashed line, and a tip side part 192 deformed after the collision is indicated by a dotted line.

[0036] An air-cooled oil cooler 22, an air conditioner heat exchanger 24, and a radiator 25 are arranged as the heat exchanger 11 on the rear side of the air guide structure 12. The air-cooled oil cooler 22 is a heat exchanger that cools oil. The air conditioner heat exchanger 24 is a heat exchanger of a refrigeration cycle that air-conditions the passenger compartment, such as a condenser. The radiator 25 is a heat exchanger that cools the coolant of the vehicle 10.

[0037] When a minor collision occurs, the front end of the front hood 14, the front grille 15, and the bumper face 16 are deformed rearward within a minor collision stroke 17. Here, the minor collision stroke 17 is the maximum distance that the front hood 14, the front grille 15, the bumper face 16, etc., constituting the front part of the vehicle, can be displaced rearward when a minor collision occurs.

[0038] In the front-rear direction, the front end of the base material portion 191, i.e., the bending starting point 193, is disposed at a position equivalent to the stroke 17 during a light collision or further rearward than the stroke 17 during a light collision. The length of the tip side portion 192 in the front-rear direction is set to a length such that when the tip side portion 192 is bent due to the occurrence of a light collision, the front end does not interfere with the heat exchanger 11, here the air-cooled oil cooler 22. Furthermore, in the front-rear direction of the vehicle, the base material portion 191 is set to be longer than the tip side portion 192. Furthermore, the base material portion 191 can also be set to be shorter than the tip side portion 192 in the front-rear direction of the vehicle.

[0039] From the above, when a minor collision occurs, the tip side portion 192 of the upper air guide 19, which is inclined downward toward the front, is pushed by the front grille 15, etc., which deforms toward the rear of the vehicle, and bends downward with the bending starting point 193 as a fulcrum. In addition, the tip side portion 192 bends downward because the rib 1951 is formed on the upper surface of the tip side portion 192. In addition, the base material portion 191 of the upper air guide 19 is reinforced by the above-mentioned rib 194, thereby supporting the tip side portion 192 from the rear. Therefore, excessive deformation toward the rear of the tip side portion 192 is suppressed, the tip side portion 192 does not interfere with the air-cooled oil cooler 22, etc., and the heat exchange function of the air-cooled oil cooler 22, etc. is not lost.

[0040] FIG. 6 is a side cross-sectional view showing the front part of the vehicle 10 when a minor collision occurs.

[0041] As described above, the tip side portion 192 of the upper air guide 19 is configured not to interfere with the air-cooled oil cooler 22 and the like during a minor collision. In addition, when a minor collision occurs and the tip side portion 192 is bent toward the air-cooled oil cooler 22 and the like, a part of the air-cooled oil cooler 22 and the like faces the front of the vehicle. That is, the bent tip side portion 192 covers only the upper part of the air-cooled oil cooler 22 from the front, and the lower part of the air-cooled oil cooler 22 faces the front of the vehicle. In this way, even after a minor collision occurs, air can be circulated to the lower parts of the air-cooled oil cooler 22, the air conditioner heat exchanger 24, and the radiator 25, and the heat exchange function of these devices can be secured. Therefore, even after a minor collision occurs at the front of the vehicle, the heat exchange function of the air-cooled oil cooler 22, the air conditioner heat exchanger 24, and the radiator 25 is secured, and the vehicle 10 can continue to run.

[0042] FIG. 7 is a front view showing the air guide 13 when a minor collision occurs.

[0043] Here, a soft portion made of rubber, elastomer, or the like having better flexibility than the main body of the air guide 13 is formed on the periphery of each air guide constituting the air guide 13. Specifically, a soft portion 196 shown by hatching is formed on the front edge of the tip side portion 192 of the upper air guide 19. A soft portion 206 shown by hatching is formed on the periphery of the tip side portion 202 of the left air guide 20. A soft portion 216 shown by hatching is formed on the periphery of the tip side portion 212 of the right air guide 21.

[0044] When a minor collision occurs, as described above, the tip side portion 192 of the upper air guide 19 bends downward. The tip side portion 202 of the left air guide 20 bends toward the right, which is the inside of the vehicle. The tip side portion 212 of the right air guide 21 bends toward the left, which is the inside of the vehicle. In this manner, the soft portion 196 of the tip side portion 192, the soft portion 206 of the tip side portion 202, and the soft portion 216 of the tip side portion 212 come into contact with each other. Since the soft portion 196, the soft portion 206, and the soft portion 216 are made of a soft material such as rubber, they are prevented from being damaged by contact with each other. Therefore, the heat exchanger 11 is prevented from being damaged by the damaged tip side portion 192, etc.

[0045] FIG. 8 is a top view showing the air guide 13 before a light collision occurs.

[0046] When no minor collision has occurred, the contact portions 197 and 198 formed on both left and right ends of the upper air guide 19 are spaced apart from the front end of the support portion 18 on the vehicle body side. The support portion 18 is a rigid member of the vehicle body, and is, for example, a part of the radiator panel 23 shown in FIG.

[0047] FIG. 9A is a top view showing air guide 13 after a minor collision has occurred, FIG. 9B is a perspective view showing the front part of vehicle 10, and FIG. 9C is an enlarged perspective view showing a key portion.

[0048] 9A and 9B, when a light collision occurs, the tip side portion 192 of the upper air guide 19 is bent downward. At this time, as shown in FIG. 5, the tip side portion 192 does not interfere with the heat exchanger 11.

[0049] 9A, the tip side portion 202 of the left air guide 20 and the tip side portion 212 of the right air guide 21 are bent outward in the width direction. Specifically, the tip side portion 202 is bent toward the left side, and the tip side portion 212 is bent toward the right side. In this manner, the tip side portions 202 and 212 can be prevented from interfering with the heat exchanger 11 in the event of a minor collision.

[0050] 9C, tip side portion 192 is bent downward from bend starting point 193. Tip side portion 192 at the bent portion abuts against, for example, radiator panel 23 shown in FIG. 1. Therefore, even if an unexpected collision exceeding a minor collision occurs at the front of the vehicle, excessive bending of tip side portion 192 is suppressed, and tip side portion 192 is prevented from interfering with heat exchanger 11.

[0051] The above-described embodiment can provide the following main effects.

[0052] 5, when a minor collision occurs, the bent tip side portion 192 does not interfere with the heat exchanger 11, and damage to the heat exchanger 11 can be prevented. Therefore, the vehicle 10 can be driven continuously after the minor collision and the vehicle 10 can be brought into a repair shop or the like.

[0053] 5, when a light collision occurs, the tip side portion 192 bends with the bending starting point 193 as a fulcrum, thereby reducing the resistance at the time of the collision. Also, the base material portion 191, which does not bend during a light collision, is disposed in a range that does not interfere with the stroke 17 during a light collision, so that the base material portion 191 does not impede shock absorption. Also, the tip side portion 192 having the rib 195 bends during a light collision and does not interfere with the heat exchanger 11, thereby preventing the heat exchanger 11 from being damaged.

[0054] Furthermore, referring to Figure 5, when a minor collision occurs, the tip side portion 192 of the upper air guide 19 bends downward, and as shown in Figure 7, the tip side portions 202 and 212 of the left air guide 20 and the right air guide 21 bend toward the inside of the vehicle, thereby preventing each air guide 13 from damaging surrounding vehicle 10 components.

[0055] 6, even after a minor collision occurs, a part of the heat exchanger 11 faces the front of the vehicle, so that at least a part of the function of the heat exchanger 11 can be ensured. Therefore, even after a minor collision, the vehicle 10 can continue to be driven.

[0056] Furthermore, referring to FIG. 5, by setting the base portion 191 to be longer than the tip side portion 192, it is possible to prevent the tip side portion 192 from interfering with the heat exchanger 11 when the tip side portion 192 is bent toward the heat exchanger 11 during a minor collision.

[0057] Furthermore, as shown in FIG. 7, the outer periphery of the upper air guide 19, the left air guide 20 and the right air guide 21 is made up of soft section 196, soft section 206 and soft section 216, which not only ensures sealing when guiding air, but also prevents the air guide 13, which is bent during a minor collision, from interfering with other vehicle components.

[0058] Furthermore, referring to FIG. 5, the bending direction of the tip side portion 192 is restricted to the downward direction, toward the heat exchanger 11, so that in the event of a minor collision, the bent tip side portion 192 does not interfere with the heat exchanger 11, thereby preventing damage to the heat exchanger 11.

[0059] Furthermore, referring to Figure 9B, when a minor collision occurs, the tip side portion 192 of the upper air guide 19 bends downward, and the base material portion 201 and tip side portion 202 of the left air guide 20 and the right air guide 21 bend toward the outside of the vehicle, thereby preventing each air guide 13 from damaging surrounding vehicle components.

[0060] Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and modifications can be made without departing from the scope of the present invention. In addition, the above-described embodiments can be combined with each other.

[0061] 3B, for example, the rib 195 may be omitted from the tip side portion 192. Even in such a configuration, the tip side portion 192 is inclined downward toward the front, so that the tip side portion 192 can be bent downward when a minor collision occurs. [Explanation of symbols]
