Description

  The present invention relates to a seal location determination method and a seal structure, and in particular, an air guide plate that is disposed at the front of an automobile and guides an airflow (running wind) generated when the automobile travels to a cooling system component, and its surroundings. The present invention relates to a method for determining a seal portion that partially seals a gap formed between automotive parts arranged in the vehicle and a structure for partially sealing such a gap.

  2. Description of the Related Art Conventionally, an air guide plate is disposed at the front of an automobile in order to increase the cooling efficiency of so-called cooling system components such as a radiator and an air conditioning condenser. For example, as disclosed in Japanese Patent Laid-Open No. 2001-80371 (Patent Document 1) and the like, the air guide plate has a guide surface that guides the traveling air to the cooling system components. A pair of such air guide plates is arranged between the cooling system component and the front bumper (bumper cover) so as to extend in the vehicle front-rear direction with the guide surfaces facing each other in the vehicle width direction. ing. Further, the air guide plates are arranged so as to connect the lower end portions or the upper end portions of the pair of air guide plates in addition to the pair of guide surfaces arranged opposite to each other in the vehicle width direction. There is also.

  By installing such a wind guide plate, the cooling efficiency of the cooling system parts can be improved, so that it is not necessary to take in unnecessary air into the engine room, etc., and aerodynamic performance is improved, thereby improving fuel efficiency. Can be envisioned. Further, it is possible to reduce the size of cooling system parts such as a radiator, and it is possible to achieve an improvement in fuel consumption by reducing the vehicle weight. In addition, the same radiator can be used universally from a large vehicle to a small vehicle, thereby reducing the cost due to the mass production effect.

  By the way, in general, when different automotive parts are assembled in close proximity to each other in an automobile, the automobile parts come into contact with each other due to input vibration or the like while the automobile is running and generate abnormal noise. In order to prevent the automobile parts from being damaged or deformed, a predetermined gap, a so-called design gap, is formed between the automobile parts adjacent to each other. For this reason, even when a wind guide plate, which is a kind of automotive component, is arranged in the front part of the automobile, a gap is inevitable between the wind guide plate and the automotive components arranged around the wind guide plate. Formed.

  However, if a gap is formed between the wind guide plate and the automotive parts located around it, the wind guided by the guide surface of the wind guide plate escapes to the outside through the gap, Accordingly, the cooling efficiency of the cooling system components is reduced. In addition, hot air from the engine may be sent to the cooling system component side through such a gap, and in such a case, the cooling efficiency of the cooling system component may be lowered.

  Therefore, conventionally, a seal portion made of various cushion materials is attached so as to fill the gap in the gap between the air guide plate and the automotive parts located around the air guide plate, or the air guide plate. For example, a flexible lip-shaped seal portion is integrally formed with respect to the outer peripheral portion, and the space between the air guide plate and the automotive part is sealed by these seal portions.

  In addition, when providing a seal part in the gap between the air guide plate and the automotive part, the seal part is not always provided in the entire gap. A seal part may be provided only in a part of the gap between the two. For example, when it is desired to reduce the formation cost of the seal portion, the gap between the air guide plate and the automotive part is partially sealed. In addition, when cooling equipment and components such as engine mounts, drive shafts, and exhaust manifolds that are relatively hot except for cooling system parts by running wind, there are some gaps between the air guide plate and automotive parts. As a result of being sealed, a gap portion where no seal portion is provided is intentionally formed, and the wind that escapes from this gap portion is used to cool a device or member that has a relatively high temperature.

  When partially sealing the gap between the air guide plate and the automotive part, the cooling system by the wind guided by the air guide plate due to the air passing through the gap portion where the seal portion is not provided. It is necessary to appropriately determine the seal location (the gap where the seal portion is provided) from the entire gap so that the cooling efficiency of the component does not decrease, that is, the cooling efficiency of the cooling system component can be sufficiently secured. .

  However, conventionally, in consideration of workability and cost in forming the seal portion, the seal portion may be provided in a portion where the seal portion is easily formed in the gap between the air guide plate and the automotive part. There were many.

  For example, as shown in Japanese Patent Application Laid-Open No. 2005-254934 (Patent Document 2) and the like, when various pipes connected to the cooling system parts and electrical wirings are arranged around the cooling system parts, the air guide plate A notch or the like for inserting the piping or electrical wiring is formed in the outer peripheral edge of the vehicle and the adjacent part with the air guide plate of the automotive part. The part adjacent to the wind guide plate of the automotive part may not be a simple shape that draws a straight line or a gentle curve, but may be a complicated shape such as a bent shape or an elliptical shape. In such a case, avoiding the gap portion formed between the outer peripheral edge of the air guide plate having a complicated shape and the adjacent portion with the air guide plate of the automotive part, with a simple shape, A gap portion where the seal portion can be easily formed is determined as a seal location, and the seal portion is provided in the gap portion.

  Thus, in the prior art, the seal location when partially sealing the gap between the air guide plate and the automotive component gives priority to the ease of forming the seal portion over the cooling efficiency of the cooling system component. Was decided. Therefore, the actual seal location provided with the seal portion is not necessarily an appropriate seal location that can sufficiently ensure the cooling efficiency of the cooling system components.

A part of the rear gap 56 located between the upper portion and the rear portion of the radiator 14 is disposed in contact with the front end of the radiator 14 in the vehicle width direction. As a result, the upper portion of the rear gap 56 is closed and sealed by the first rear seal portion 64c.

  Further, the second rear seal portion 64d is provided at the lower portion of the rear gap 56, that is, the lower portion of the front corner portion at both ends in the vehicle width direction of the radiator 14 and the rear end portion of the guide surface 16 of the air guide plate 10. A part of the rear gap 56 located between the lower part and the lower part is disposed in a state where a part thereof is in contact with the front end of the radiator 14 in the vehicle width direction. As a result, the lower portion of the rear gap 56 is closed and sealed by the second rear seal portion 64c.

  Thus, here, the gaps 54, 56, 58, 60 surround the air guide plates 10 between the two air guide plates 10, 10 and the bumper cover 12, the radiator 14, and the radiator support 48. Despite being formed, the gaps 54, 56, 58, 60 are partially sealed, so that the traveling wind guided to the radiator 14 by the guide surface 16 of each wind guide plate 10 The gaps 54, 56, 58 and 60 are prevented as much as possible.

  In the present embodiment, among the gaps 54, 56, 58, 60 between the air guide plates 10, 10 and the bumper cover 12, the radiator 14, and the radiator support 48, the five seal portions 64 a to 64 e are formed. The seal location to be sealed is determined by a special method, for example, according to the following procedure.

  That is, first, the wind pressure distribution of the guide surface 16 when the traveling wind is guided to the radiator 14 side by the guide surface 16 of the air guide plate 10 is obtained by a known method.

  As a method for obtaining the wind pressure distribution of the guide surface 16, there are a simulation method and a measurement method. As the former method, for example, there is a method in which CFD analysis is performed by a known method to obtain a wind pressure distribution on the guide surface 16 of the air guide plate 10. Further, in the latter method, for example, a wind tunnel test using the air guide plate 10 is performed, and the wind pressure at various locations of the guide surface 16 at that time is measured by a known method, whereby the wind pressure of the guide surface 16 is measured. There is a method for obtaining the distribution.

  Here, preferably, the above-described simulation and actual measurement are performed using the air guide plate 10 in which the through hole 30 and the lower notch 32 are not yet provided. Further, when the wind pressure distribution of the guide surface 16 is obtained, whether the method by simulation or the method by actual measurement is adopted, not only when the vehicle is traveling straight, but also when the vehicle is turning left or right, for example. Assuming that the wind direction is oblique with respect to the car or the like, when the traveling wind is guided straight in the front-rear direction on the guide surface 16, the traveling wind is at various angles. It is desirable to obtain the wind pressure distribution of the guide surface 16 when the guide surface 16 is guided in an inclined direction. By doing so, it is possible to obtain a more appropriate wind pressure distribution on the guide surface 16 when traveling in an actual vehicle.

  Then, for example, by performing CFD analysis, the wind pressure distribution of the wind guide plate 10 as shown in FIG. 4 is obtained. In FIG. 4, the blacked-out portion indicates the portion where the wind pressure is the maximum value, and the cross-hatched portion indicates the portion where the wind pressure is higher than other portions. Yes. Moreover, the part to which the dot is attached indicates the part where the wind pressure is lower than the peak value, and the part to which the broken hatch is attached has a lower wind pressure than the part to which the dot is attached. The part is shown.

  Next, the peak portion and the maximum portion of the wind pressure on the guide surface 16 are specified based on the wind pressure portion of the guide surface 16 of the air guide plate 10 obtained as described above.

  That is, as shown in FIG. 4, the front notch 26 is defined as a first front wind pressure peak portion 66 a that is an upper portion of the front end portion of the guide surface 16 of the air guide plate 10 that is located above the front notch 26. An intermediate portion extending along the lower peripheral edge is specified as the second front wind pressure peak portion 66b, and the lower corner is specified as the third front wind pressure peak portion 66c. On the other hand, of the rear end portion of the guide surface, a portion located at substantially the same height as the first front wind pressure peak portion 66a is defined as a first rear wind pressure peak portion 66d, and a lower portion including a lower corner portion is defined. The second rear wind pressure peak portion 66e is specified. Then, the lower corner portion and its peripheral portion located in the second rear wind pressure peak portion 66 e are specified as the wind pressure maximum portion 68. As described above, in the present embodiment, the five wind pressure peak portions 66a to 66e constitute the wind pressure peak wind guide plate portion, and the wind pressure maximum portion 68 constitutes the wind pressure maximum wind guide plate portion. Yes.

  Here, the wind pressure distribution of the guide surface 16 is determined using the air guide plate 10 in which the through hole 30 and the lower notch 32 are not yet provided. Therefore, after the peak portion and the maximum portion of the wind pressure on the guide surface 16 are specified, the formation locations of the through hole 30 and the lower cutout portion 32 are determined respectively.

  As described above, the through-hole 30 allows the harness or the like to be inserted into the upper portion of the wind guide plate 10 with the wind guide plate 10 installed in the engine room. A gap is inevitably formed between the insertion portion of the harness and the inner peripheral surface of the through hole 30, and this serves as a passage for the traveling wind guided by the guide surface 16. Therefore, the through hole 30 is formed in a portion of the upper portion of the guide surface 16 of the air guide plate 10 where the wind pressure is as small as possible in order to reduce the amount of running wind extracted from such a passage as much as possible. It is desirable. Therefore, here, as shown in FIG. 4, the first front wind pressure peak portion 66 a and the first rear wind pressure peak portion 66 d in the upper portion of the guide surface 16, and the wind pressures positioned around them are relatively large. The portion where the through hole 30 is formed is set in a higher portion, that is, a portion different from the portion indicated by dots in FIG. 4 or the portion indicated by a broken hatch. That is, as shown by a two-dot chain line in FIG. 4, a portion satisfying the above conditions, a middle portion in the front-rear direction of the guide surface 16 and a portion directly above the front cutout portion 26 are formed as through-hole forming portions 70. It is decided.

  The lower notch 32 also allows the pipe 34 to be inserted into the lower end of the wind guide plate 10 in a state where the wind guide plate 10 is installed in the engine room, as described above. When inserted, a gap is inevitably formed between the insertion portion of the pipe 34 and the inner peripheral surface of the lower cutout portion 32, and this is the passage of the traveling wind guided by the guide surface 16. Become. Therefore, the lower cutout 32 is a portion of the lower end portion of the guide surface 16 of the air guide plate 10 where the wind pressure is as small as possible from the viewpoint of reducing the amount of running wind extracted from such a passage as much as possible. It is desirable to be formed. Therefore, here, as shown in FIG. 4, in the lower end portion of the guide surface 16, the third front wind pressure peak portion 66c, the maximum wind pressure portion 68, and the second rear wind pressure peak portion 66e are different portions. In addition, the lower notch 32 is located at a portion where the wind pressure is relatively high and located in the vicinity thereof, that is, a portion where a dot or a hatched portion in FIG. 4 is avoided as much as possible. The formation location is set. Thus, as indicated by a two-dot chain line in FIG. 4, the middle part in the front-rear direction of the lower end of the guide surface 16 that satisfies the above conditions is determined as the lower notch forming portion 72. is there.

  Then, when the through hole forming portion 70 and the lower notch forming portion 72 are determined, the through hole 30 is formed in the through hole forming portion 70, while the lower notch 32 is formed in the lower notch forming portion 72. The air guide plate 10 is usually manufactured by mold molding such as injection molding. Therefore, actually, the through-hole forming portion 70 and the lower notch forming portion 72 are connected to the wind guide plate based on the wind pressure distribution on the guide surface 16 obtained by simulation or actual measurement using the model of the wind guide plate 10. Before the manufacture of 10, the through hole 30 and the lower notch 32 are formed on the air guide plate 10 at the same time as the manufacture of the air guide plate 10 by die molding. Of course, using the air guide plate 10 used in the actual vehicle, the through hole forming portion 70 and the lower notch forming portion 72 are determined, and then the through hole forming portion 70 and the lower notch of the air guide plate 10 are determined. It is also possible to form the through hole 30 and the lower cutout portion 32 with respect to the portion forming portion 72.

  Next, as shown in FIG. 5, the two air guide plates 10 in which the through hole 30 and the lower notch 32 are formed and the five wind pressure peak portions 66 a to 66 e and the maximum wind pressure portion 68 are specified. 10 (only one air guide plate 10 is shown in FIG. 5), the guide surfaces 16 are actually opposed to each other between the bumper cover 12 and the radiator 14 in the engine compartment, It arrange | positions so that it may extend, and it fixes to the bumper reinforcement 33 and the shroud 36 as mentioned above. At this time, the front gap 54, the rear gap 56, the upper gap 58, and the lower gap 60 are provided between the two wind guide plates 10, 10 and the bumper cover 12, the radiator 14, and the radiator support 48. It is formed so as to surround the periphery of the plate 10.

  Thereafter, a portion to be sealed is determined from the gaps 54, 56, 58, 60 formed between the two air guide plates 10, 10 and the bumper cover 12, the radiator 14, and the radiator support 48. Among the gaps 54, 56, 58, 60, the seal locations are the wind guide plate 10 portion including the five wind pressure peak portions 66 a to 66 e and the maximum wind pressure portion 68 of the guide surface 16, the bumper cover 12 and the radiator 14. And a portion located between the radiator support 48 and the radiator support 48.

  That is, as is apparent from FIG. 5, the front end face 18 of the air guide plate 10 is continuous (positioned adjacent to) the first front wind pressure peak portion 66a of the guide surface 16 and the guide surface 16 portion including the periphery thereof. The front gap portion 54 located between the upper portion and the upper portion of the inner surface of the bumper cover 12 is determined as the first front seal portion 74a.

  Further, the lower part end surface 24 and the lower end face 24 of the front end face 18 of the air guide plate 10 that are continuous (adjacent to) the third front side wind pressure peak part 66c of the guide face 16 and the guide face 16 part including the periphery thereof. The front gap part 54 and the lower gap 60 part located between the front part and the lower part of the inner surface of the bumper cover 12 are determined as the second front seal part 74b.

  Furthermore, a rear gap 56 portion located between the first rear wind pressure peak portion 66d of the guide surface 16 and its peripheral portion and the upper portions of the front corners at both ends in the vehicle width direction of the radiator 14 is provided as the first rear. The side seal location 74c is determined.

  Further, the rear gap 56 located between the maximum wind pressure portion 68 and the second rear wind pressure peak portion 66e of the guide surface 16 and their peripheral portions and the lower portions of the front corners at both ends of the radiator 14 in the vehicle width direction. The portion is determined as the second rear seal portion 74d.

  Further, the lower end face 24 of the wind guide plate 10 is continuous (positioned adjacent to) the guide surface 16 including the maximum wind pressure portion 68 and the second rear wind pressure peak portion 66e of the guide surface 16 and their peripheral portions. The lower gap 60 portion located between the rear portion and the rear portion is determined as the lower seal portion 74e.

  The intermediate portion of the front end face 18 of the air guide plate 10 that is continuous (adjacent to) the second front wind pressure peak portion 66b of the guide surface 16 and the guide surface 16 portion including the periphery thereof is a bumper hose. , And no gap is formed around the intermediate portion. For this reason, a seal | sticker location is not set in the peripheral part of the 2nd front side wind pressure peak part 66b.

  Thus, after the five seal locations 74a to 74e are determined for the front gap 54, the rear gap 56, and the lower gap 60, as shown in FIG. The front side end face 18 of the air guide plate 10 includes the front side seal part 64a, the second front side seal part 74b, the second front side seal part 64b, the lower side seal part 74e, and the lower side seal part 64e. Or installed between the lower end surface 24 and the inner surface of the bumper cover 12 and fixed to the front end surface 18 and the lower end surface 24. Further, the first rear seal portion 64c is provided for the first rear seal portion 74c, and the second rear seal portion 64d is provided for the second rear seal portion 74d. It is installed in a state where it is in contact with the end portion in the width direction and fixed to the rear end portion of the guide surface 16.

  Thus, in the present embodiment, when the guide surface 16 of the air guide plate 10 guides the traveling wind taken from the air intake port 40 of the bumper cover 12 to the radiator 14, the maximum portion of the wind pressure that the guide surface 16 receives. In addition, the front gap portion 54 and the rear gap 56 that are located between the portion of the air guide plate 10 each including a portion showing a high peak value compared to other portions, and the bumper cover 12, the radiator 14, and the radiator support 48. The portion and the lower gap 60 portion are determined as seal portions 74a to 74e, respectively, and five seal portions 64a to 64e are provided at the five seal portions 74a to 74e, respectively. In other words, the seal portions 64a to 64e are partially installed as much as necessary at locations where the seal is required among the front gap 54, the rear gap 56, the upper gap 58, and the lower gap 60. It is. In addition, the portion of the air guide plate 10 where the seal portions 64a to 64e are installed has a shape that linearly extends or a gentle curve.

  Therefore, according to the present embodiment as described above, the seal portions 74a to 74e of the gaps 54, 56, 58, and 60 are appropriately determined, and accordingly, the traveling wind from the gaps 54, 56, 58, and 60 is determined. A seal design that can reliably and efficiently prevent slipping out can be advantageously realized with the lowest possible cost and easy operation. In addition, the traveling wind that has escaped from the gaps 54, 56, 58, and 60 other than the portions where the seal portions 64a to 64e are installed can be relatively moved to the engine mount, drive shaft, exhaust manifold, and the like installed in the engine room. It can be effectively used as cooling air for a device or member that becomes high temperature.

  Further, in the present embodiment, when the through hole 30 is formed on the air guide plate 10 and the lower notch 32 is formed on the guide surface 16 when the traveling air is guided to the radiator 14 by the guide surface 16 of the air guide plate 10. Is set to a location different from the maximum location of the wind pressure received and the location where the peak value is higher than other locations, and the through hole 30 and the lower notch 32 are formed in such locations. ing.

  Therefore, air blowout from the through hole 30 and the lower notch 32 is suppressed as much as possible, and thus a further excellent sealing effect can be exhibited.

  In addition, unlike the case where the through hole 30 and the lower notch 32 are formed at the maximum wind pressure received by the guide surface 16 or at a place where the peak value is higher than other parts, these through holes 30 are provided. In addition, the formation of the lower cutout portion 32 causes a situation where the seal portions 64a to 64e have to be provided in a complicated shape rather than a simple shape extending in a straight line or a gentle curve. Can be effectively avoided. As a result, simplification of the forming operation of the seal portions 64a to 64e can be advantageously achieved. And the improvement of the cooling efficiency of the radiator 14 can be achieved very effectively by such an easy sealing operation.

  The specific configuration of the present invention has been described in detail above. However, this is merely an example, and the present invention is not limited by the above description.

  For example, in the above-described embodiment, the seal portions 64 a to 64 e are configured as separate members from the air guide plate 10, but they may be integrally formed with the air guide plate 10. In that case, the five seal locations 74a to 74e of the front side, the rear side, and the lower side gaps 54, 56, 60 determined by the above-described method are placed between the bumper cover 12, the radiator 14, and the radiator support 48. The seal pieces 76a to 76e are integrally formed with the air guide plate 10 formed in the above.

  That is, as shown in FIGS. 6 to 8, the first front wind pressure peak portion 66 a and the third front wind pressure peak portion 66 c of the guide surface 16 are continuous with the front end face 18 portion of the wind guide plate 10. The first front seal piece 76a and the second front seal piece 76b are integrally protruded. Further, the first rear seal piece 76c and the second rear seal piece 76d are integrally formed with respect to the first rear wind pressure peak portion 66d, the second rear wind pressure peak portion 66e, and the maximum wind pressure portion 68, respectively. Project. Further, the lower seal piece 76e is integrally projected on the lower end surface 24 portion of the air guide plate 10 that is continuous with the second rear wind pressure peak portion 66e and the maximum wind pressure portion 68. Here, each of the five seal pieces 76a to 76e is thinner than the main body portion of the air guide plate 10, and as a whole, has a long, narrow rectangular lip shape and is configured by a flexible flat plate. Has been.

  The five seal pieces 76a to 76e are bent and deformed at the five seal portions 74a to 74e, respectively, and the tip portions are brought into contact with the bumper cover 12, the radiator 14, and the radiator support 48. Has been placed. Thus, the front gap 54, the rear gap 56, and the lower gap 60 are partially sealed at necessary locations by the required amount. As a result, even in the present embodiment, substantially the same operations and effects as those in the first embodiment described above can be enjoyed effectively.

  Moreover, in the said embodiment, the seal locations 74a-74e, the through-hole formation location 70, and the lower notch formation location 72 were determined by performing CFD analysis only once. However, if necessary, after performing the CFD analysis a plurality of times or repeatedly measuring the wind pressure distribution of the guide surface 16 by the wind tunnel test a plurality of times, based on the wind pressure distribution of the guide surface 16 obtained thereby, The seal locations 74a to 74e, the through hole formation location 70, and the lower notch formation location 72 may be respectively determined. Thereby, the wind guide effect by the installation of the wind guide plate 10 is further enhanced.

  That is, for example, after the seal portion is installed at the seal location determined by the first CFD analysis or the wind tunnel test, the second CFD analysis or the wind tunnel test is performed, and a new wind pressure of the guide surface is obtained. Find the distribution. Therefore, if the presence of a new wind pressure maximum wind guide plate portion or a wind pressure peak wind guide plate portion is newly recognized in the wind pressure distribution of the guide surface determined therefor, a new seal location may be determined based on that.

  Also, for example, the second CFD analysis or wind tunnel test is performed under the condition that the seal portion is provided at the seal location determined based on the wind pressure distribution of the guide surface obtained by the first CFD analysis or wind tunnel test. From the wind pressure part of the guide surface obtained by performing the above, etc., make the through-hole formation part and the lower notch part formation part the optimum part different from the wind pressure maximum wind guide plate part and wind pressure peak wind guide plate part You may decide.

  Even if the above-mentioned CFD analysis, wind tunnel test, etc. are repeated three times or more, a new addition or correction of a seal part, or an addition or correction of a through hole forming part or a lower notch forming part is performed. It ’s good.

  In the embodiment, the air guide plate 10 including the maximum air pressure portion 68 of the guide surface 16, the air guide plate 10 including the air pressure peak portions 66 a to 66 e, the bumper cover 12, the radiator 14, and the radiator support 48 are provided. Seal locations 74a to 74e were set for the gaps 54, 56, and 60 formed between the two. However, for example, when the wind pressure of the wind pressure peak portions 66a to 66e is not so high, or when a particularly high wind guide effect is not required, the wind guide plate 10 portion including the maximum wind pressure portion 68 of the guide surface 16; A seal location may be set only for the gaps 54, 56, and 60 formed between the bumper cover 12, the radiator 14, and the radiator support 48, and a seal portion may be provided there.

  In addition, in the above-described embodiment, the present invention partially seals the gap formed between the air guide plate that guides the traveling wind to the radiator and the bumper cover, shroud, and radiator support disposed around the wind guide plate. At the time, the method of determining the seal portion of the gap and an example applied to the seal structure of the gap were shown, but the present invention is a wind guide plate that guides the running wind to cooling system parts other than the radiator, When partially sealing the gap formed between the various automotive parts arranged around it, both the method for determining the seal location of the gap and the seal structure of the gap Of course, it can be advantageously applied.

  In addition, although not enumerated one by one, the present invention can be carried out in a mode to which various changes, modifications, improvements, etc. are added based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the present invention.
