By the way, the intake cover has a configuration in which an upper wall that defines the upper side of the flow path for introducing outside air and a lower wall that defines the lower side of the flow path are connected in the vertical direction by a connecting member. It is possible to employ a configuration in which the air intake section, which is provided and air is taken in by the air conditioning unit in the passenger compartment, is connected by a connecting member in the vertical direction. However, with such a configuration, when an external force is applied to the intake cover from above, the connecting member is stretched, and the reaction force of the connecting member hinders deformation of the intake cover. As a result, it becomes difficult to efficiently absorb the impact when receiving an external force.

If an upper wall and a lower wall are connected by a connecting member, for example, if an external force is applied to the resin cover from above, the reaction force of the connecting member Deformation of the cover is inhibited.

In view of such problems, the present invention provides a vehicle front cover that can promote deformation of the intake cover and the resin cover when an external force is applied from above even if the interior of the intake cover and the resin cover is connected in the vertical direction. The purpose is to provide a part structure and a resin cover.

In order to solve the above-described problems, a representative configuration of the vehicle front structure according to the present invention is an air intake section provided in a dash panel that separates the vehicle front and the vehicle interior, in which air is taken in by an air conditioning unit in the vehicle interior. and an intake cover forming a flow path for guiding outside air introduced from the cowl to the front of the vehicle to the intake section, the intake cover comprising: an upper wall defining the upper side of the flow path; a pair of side walls extending continuously from both ends of the upper wall in the vehicle width direction to the dash panel and defining both sides of the flow path in the vehicle width direction; at least one support extending from the top wall and connected to the coupling to support the coupling, wherein at least one of the at least one support extends in a direction non-perpendicular to the top wall. Characterized by

In order to solve the above problems, a representative configuration of a resin cover according to the present invention includes a pair of side walls spaced apart in a predetermined direction and an outer wall connecting the pair of side walls. In the resin cover mounted on the vehicle by partitioning a space surrounded by the outer wall and the outer wall, the resin cover further includes a connecting portion connected to a predetermined lower member below the outer wall, and a connecting portion extending from the outer wall to support the connecting portion. The at least one support portion is inclined so as to approach the center of the outer wall as it goes from the outer wall toward the connection portion, and the end portion of the support portion on the connection portion side is the support portion is lower in rigidity than the end portion on the outer wall side of the

ADVANTAGE OF THE INVENTION According to the present invention, even if the inside of the intake cover and the resin cover are connected in the vertical direction, the deformation of the intake cover and the resin cover can be promoted when an external force is applied from above, and the resin cover and the vehicle front structure. can be provided.

It is a figure which shows the vehicle front part structure which concerns on the Example of this invention. FIG. 2 is a diagram showing a main part of the vehicle front structure of FIG. 1; FIG. 2 is a view showing an intake cover of the vehicle front structure of FIG. 1; FIG. 4 is a diagram showing a state in which the intake cover of FIG. 3 is viewed from another direction; It is a figure which shows each cross section of the intake cover of FIG.4(b). FIG. 4 is a diagram showing a state in which the intake cover of FIG. 3 is viewed from another direction; It is a figure which shows the case where external force is applied to the intake cover of Fig.1 (a) from upper direction with a modification. It is a figure which shows typically the other modification of the intake cover of Fig.5 (a).

A representative configuration of a vehicle front structure according to an embodiment of the present invention includes an air intake section provided in a dash panel that separates a vehicle front section from a vehicle interior and through which air is drawn in by an air conditioning unit in the vehicle interior, and a cowl. In a vehicle front structure including an air intake cover that forms a flow path for guiding outside air introduced from a section into the front portion of the vehicle to an intake section, the intake cover includes an upper wall that defines the upper side of the flow path, and an upper wall that defines the flow path. A pair of side walls extending continuously from both ends in the vehicle width direction to the dash panel and partitioning both sides in the vehicle width direction of the flow path, a connection portion connected to the intake portion or the dash panel below the upper wall, and a connecting portion from the upper wall. and at least one support extending and connected to and supporting the coupling, wherein at least one of the at least one support extends in a direction non-perpendicular to the top wall. .

In the above configuration, the connection part of the intake cover is connected to the intake part or the dash panel arranged below the upper wall, and further connected to the support part. If the intake cover has a lower wall that defines the lower side of the flow path, the connecting portion may be connected to the lower wall instead of the intake portion or the dash panel. Further, the supporting portion supports the connecting portion and extends in a non-perpendicular direction to the upper wall and is inclined.

As a result, when an external force is applied to the intake cover from above, the supporting portion is easily deformed in the inclined direction. Therefore, according to the above configuration, the deformation of the intake cover can be promoted even if the intake part or the dash panel is vertically connected by the connecting part in the flow path of the intake cover.

Preferably, the connection area between the at least one support and the connecting part has a lower stiffness than the connection area between the top wall and the at least one support.

Accordingly, when an external force is applied to the intake cover from above, the supporting portion is deformed in an inclined direction, and the connecting region between the supporting portion and the connecting portion can be broken. As a result, the impact energy when receiving an external force can be used as energy for breaking the connecting region between the supporting portion and the connecting portion, or for deforming the supporting portion and its surroundings. Therefore, according to the above configuration, it is possible to efficiently absorb the impact when an external force is applied to the intake cover from above.

It is preferable that the at least one support portion is formed so that the cross-sectional area decreases from the upper wall toward the connecting portion.

As a result, when the intake cover receives an external force from above and impact energy is transmitted from above to below the support, it is possible to avoid local stress concentration within the support. Therefore, unintended deformation of the support portion does not occur, and the support portion is not prevented from being deformed in an inclined direction and further from being broken in connection with the connecting portion.

The at least one support portion may have a pair of support portions arranged side by side in a predetermined direction, and at least one of the pair of support portions may be inclined.

Accordingly, when an external force is applied to the intake cover from above, at least one of the pair of support portions is likely to deform in the inclined direction, thereby promoting deformation of the intake cover. The predetermined direction is not limited to the vehicle width direction, and may be the vehicle front-rear direction.

The pair of support portions may be inclined in a predetermined direction so as to be spaced apart from each other toward the lower surface of the upper wall from the connecting portion.

As a result, the pair of support portions are in a state of being opened in an inverted V shape. Therefore, even when an external force received from above the intake cover acts on one side or the other side of the intake cover in a predetermined direction, the pair of support portions are easily deformed in the inclined direction, and the support portion and the connecting portion are easily deformed. It is easy to promote breakage of the connection area with.

A gap is preferably formed between the pair of support portions. Since a gap is formed between the pair of support portions in this manner, when an external force is applied to the intake cover from above, the pair of support portions are easily deformed in the inclined direction.

A weakened portion that is weaker than the periphery in the direction in which the at least one support portion extends may be formed in the connection region between the at least one support portion and the connecting portion.

Accordingly, when an external force is applied to the intake cover from above, the supporting portion can be reliably deformed in an inclined direction due to the fragile portion formed in the connection area with the connecting portion, and the connection area is broken. be able to. The fragile portion may be thinned or provided with at least one opening, notch, hole, or hole.

The intake section is arranged so as to protrude upward from the dash panel, the connecting section of the intake cover is superimposed on the intake section and connected with a predetermined fastening member, and the pair of support sections is connected to the connecting section. The air intake cover is arranged on both sides in the vehicle width direction of the air intake cover, and is inclined so as to approach each other from the upper wall toward the connecting portion. It is preferable to have a sealing member that seals the

Accordingly, when the sealing member seals the gap between the outside of the rear portion of the intake cover and another member such as the dash panel, the repulsive force (reaction force) of the sealing member acts on the rear portion of the intake cover. This repulsive force is transmitted to the intake section via the pair of support sections of the intake cover, the connecting section, and the fastening member. As a result, even if there are few connection points between other members such as the dash panel and the air intake portion, the gap can be easily sealed.

The connecting portion has a pair of ribs that are spaced apart in the vehicle width direction and extend in the vehicle front-rear direction, the pair of support portions are connected to the pair of ribs, respectively, and the pair of support portions and the pair of ribs , and is set longitudinally in the vehicle front-rear direction, and in each connection region between the pair of support portions and the pair of ribs, there is a weakened portion that is thinner in the vehicle width direction and is weaker than the periphery extending in the vehicle front-rear direction. It should be formed.

As a result, when an external force is applied to the intake cover from above, the pair of support portions can be reliably deformed in an inclined direction by the thin fragile portions formed in the respective connecting regions with the pair of ribs. , and furthermore the connection area can be broken. Therefore, the intake cover is not prevented from being deformed when receiving an external force from above.

The upper wall of the intake cover has a rising portion that slopes upward as it goes rearward from a position behind the connecting portion, and a falling portion that continues to the rising portion and slopes downward as it goes rearward. It is preferable that the stop member is provided on the falling portion, and the rear end portions of the pair of supporting portions are inclined along the rising portion.

In this manner, the sealing member is provided at the trailing portion of the upper wall of the intake cover. For this reason, the repulsive force of the sealing member is transmitted from the falling portion of the upper wall portion to the rising portion, further reliably transmitted to the rear end portions of the pair of support portions inclined along the rising portion, and further connected. It is transmitted to the intake section via the section and the fastening member. As a result, even if the number of connection points between the other member such as the dash panel and the air intake portion is small, the gap can be easily sealed.

A representative configuration of a resin cover according to an embodiment of the present invention includes a pair of side walls spaced apart in a predetermined direction and an outer wall connecting the pair of side walls. A resin cover that partitions an enclosed space and is mounted on a vehicle, the resin cover further comprising: a connecting portion connected to a predetermined lower member below the outer wall; and at least one member extending from the outer wall and supporting the connecting portion. at least one supporting portion is inclined so as to approach the center of the outer wall as it goes from the outer wall toward the connecting portion, and the end of the supporting portion on the connecting portion side is located on the outer wall side of the supporting portion. characterized by being less rigid than the ends of the

In the above configuration, the connecting portion of the resin cover is connected to a predetermined lower member arranged below the outer wall and further connected to the supporting portion. The supporting portion supports the connecting portion and is inclined so as to approach the center of the outer wall from the outer wall toward the connecting portion.

As a result, when the outer wall of the resin cover receives an external force that deforms toward the inside of the vehicle, for example, the supporting portion is easily deformed in the direction in which the supporting portion is inclined, that is, in the direction in which the outer wall is inclined closer to the center of the outer wall toward the connecting portion. Therefore, the impact energy accompanying the external force can be used as energy for deforming the supporting portion and its surroundings or breaking the end portion of the supporting portion on the connecting portion side. Therefore, according to the above configuration, it is possible to efficiently absorb the impact when receiving an external force that deforms the outer wall of the resin cover.

FIG. 3 is a diagram showing the intake cover 104 of the vehicle front structure 100 of FIG. FIG. 3(a) is a diagram showing a state in which the intake cover 104 is viewed obliquely from below. 3B is a front view of the intake cover 104. FIG.

The connecting portion 130 of the intake cover 104 has a pair of ribs 154 and 156 and a connecting surface 158 as shown in FIG. 3(a). The pair of ribs 154 and 156 are spaced apart in the vehicle width direction and extend in the vehicle front-rear direction, and are connected by a connection surface 158 .

A pair of support portions 132 and 134 have a gap 159 formed therebetween and are further connected to a pair of ribs 154 and 156, respectively. The pair of support portions 132, 134 and the pair of ribs 154, 156 are set longitudinally in the vehicle front-rear direction.

Further, as shown in FIG. 3B, the pair of support portions 132 and 134 are inclined so as to separate from each other as they go from the connecting portion 130 toward the upper wall 124, and are in a state of being opened in an inverted V shape. It has become. That is, the pair of support portions 132 , 134 extend in a direction that is not perpendicular to the top wall 124 .

Furthermore, as shown in FIG. 3A, weakened portions 164, 166 which are weaker than the surroundings are formed in connection regions 160, 162 of the pair of support portions 132, 134 and the pair of ribs 154, 156, respectively. ing. The fragile portions 164 and 166 are thin in the vehicle width direction and extend in the vehicle front-rear direction. Therefore, connection regions 160, 162 between the pair of support portions 132, 134 and the pair of ribs 154, 156, respectively, are stiffer than connection regions 168, 170 between the upper wall 124 and the pair of support portions 132, 134. getting low.

FIG. 4 is a diagram showing a state in which the intake cover 104 of FIG. 3 is viewed from another direction. 4A is a left side view of the intake cover 104. FIG. FIG. 4B is a diagram showing a state in which the intake cover 104 is viewed obliquely from the upper left.

As shown in FIG. 4A, the upper wall 124 of the intake cover 104 extends further to the front side of the vehicle than the edge 172 of the side wall 128 that contacts the base surface 110 of the dash panel 106 . A leading edge 174 of sidewall 128 also has a ramp 176 and an extension 178 . Inclined portion 176 is inclined from base surface 110 of dash panel 106 so as to approach upper wall 124 toward the front side of the vehicle. Extension 178 extends continuously upward from front end 180 of ramp 176 to reach front end 182 of top wall 124 .

Side wall 126 likewise has a sloped portion 186 and an extension 188 at its leading edge 184, as shown in FIG. 3(a). Inclined portion 186 is inclined from edge 190 in contact with base surface 110 of dash panel 106 so as to approach upper wall 124 toward the front side of the vehicle. Extension 188 extends continuously upward from front end 192 of ramp 186 to reach front end 182 of top wall 124 .

Thus, in the intake cover 104, the front edges 174, 184 of the pair of side walls 128, 126 are provided with inclined portions 176, 186 and extended portions 178, 188, respectively. This results in areas 194, 196 defined by ramps 176, 186, extensions 178, 188, and lines B, C connecting edges 172, 190 on dash panel 106 and front edge 182 of top wall 124 (Fig. 3(a) and FIG. 4(a)), it is possible to make it easier to introduce outside air into the intake cover 104. As shown in FIG.

Further, in the intake cover 104, outside air introduced into the inside thereof does not escape to the outside of the partitioned regions 194, 196 of the pair of side walls 128, 126. As shown in FIG. Therefore, in the intake cover 104, it is possible to increase the amount of air flowing along the upper wall 124 by making it difficult to guide air and rainwater to the lower side while making it easier to guide air to the upper side of the pair of side walls 128 and 126. - 特許庁

Further, in the intake cover 104, as shown in FIG. 4A, the extended portion 178 and the inclined portion 176 are formed so as to project forward when viewed from the side. This makes it difficult for the load to concentrate on the connection region between the extension portion 178 and the inclined portion 176 , that is, the front end 180 and the periphery of the inclined portion 176 , thereby suppressing local deformation of the upper wall 124 . The extension portion 188 and the inclined portion 186 are similarly formed to have a forward convex shape. If the extensions 178, 188 and the slopes 176, 186 are recessed rearward, that is, in a doglegged shape, it is difficult to introduce outside air. The load concentrates on the connection point of the upper wall 124, and the upper wall 124 tends to deform locally.

Further, edge 172 of side wall 128 on dash panel 106 includes a trailing edge 200 extending downwardly from trailing edge 198 of top wall 124 and a lower edge 202, as shown in FIG. 4(b). The lower edge 202 descends toward the vehicle front side from the lower end 204 of the trailing edge 200 and continues to the front edge 174 . Note that sidewall 126 likewise includes edge 190 on dash panel 106 as shown in FIG.

3(a) and 3(b), the intake cover 104 further includes a rear wall 210 connecting the rear edges 200, 206 of the pair of side walls 128, 126, and a bulging portion 212 (FIG. 4). See). The bulging portion 212 is formed in the rear portion of the upper wall 124 in the vehicle width direction and bulges upward, and has a rising portion 214 and a falling portion 216 .

The rising portion 214 rises upward from a position behind the inclined portions 176 and 186 of the front edges 174 and 184 of the pair of side walls 128 and 126 toward the rear. The falling portion 216 continues to the rising portion 214 and falls downward toward the rear wall 210 .

Further, the trailing portion 216 and the rear wall 210 are provided with a first sealing member 218 and a second sealing member 220, respectively, shown in FIG. 3(b). The first sealing member 218 and the second sealing member 220 seal the space between the trailing portion 216 and the rear wall 210 and the dash panel 106 , and prevent water and the like from entering through these spaces. can be prevented from flowing down to the inlet 108 of the

Also shown in FIG. 3( a ), a first flange 138 with a first fixation point 142 extends from the lower edge 208 of the first side wall 126 . A second flange 140 with a second fixation point 144 extends from the trailing edge 200 of the second side wall 128 . Therefore, the first fixing point 142 and the second fixing point 144 are arranged at positions shifted in the longitudinal direction of the vehicle.

Furthermore, the intake cover 104 has a lower surface portion 222 . The lower surface portion 222 extends in the vehicle width direction from the lower edge 202 of the second side wall 128 and further extends from the second flange 140 toward the front side of the vehicle. Further, the lower surface portion 222 is not provided with a fixing point. Thus, the lower surface portion 222 and the front edge 174 and the lower edge 202 of the second side wall 128 are free ends. Note that the front edge 184 of the first side wall 126 shown in FIG. 3B is also a free end.

Thus, the intake cover 104 is provided with a first fixing point 142 on a first flange 138 extending from the lower edge 208 of the first side wall 126 and behind the second side wall 128 as shown in FIG. A second fixing point 144 is provided on the second flange 140 extending from the rim 200 , but no fixing point is provided on the lower surface portion 222 that is continuous with the second side wall 128 . As a result, in the intake cover 104, the fixing directions of the first fixing point 142 and the second fixing point 144 are made different to promote torsional deformation of the first side wall 126 or the second side wall 128, while the second fixing point not provided with the fixing point The lower surface portion 222 that is continuous with the two side walls 128 can be made easier to displace in the vehicle width direction than the lower surface of the first side wall 126 , that is, the first flange 138 that is continuous with the first side wall 126 .

Thus, the front edges 174, 184 of the pair of side walls 128, 126 have inclined portions 176, 186 that approach the top wall 124 from the dash panel 106 toward the vehicle front side. The inclined portions 176 and 186 approach the upper wall 124 as they go from the dash panel 106 toward the front side of the vehicle. Therefore, the support area for the pair of side walls 128 and 126 to support the dash panel 106 can be reduced.

If the front edges 174, 184 of the pair of side walls 128, 126 do not have the inclined portions 176, 186, and are continuous from both ends of the upper wall 124 in the vehicle width direction, they extend downward toward the base surface 110 of the dash panel 106. , the supporting area for the pair of side walls 128, 126 to support the dash panel 106 becomes larger than in the configuration having the inclined portions 176, 186 described above.

Therefore, when an external force is applied to the upper wall 124 of the intake cover 104 from above, the external force transmitted to the front portion including the front end 182 of the upper wall 124 and its periphery is transmitted from the upper wall 124 to the pair of side walls. Along the inclined portions 176, 186 of the front edges 174, 184 of the pair of side walls 128, 126, the lower edges 202, 208 and their periphery shown in FIG. is transmitted to the lower end including As a result, while suppressing the front portion of the upper wall 124 of the intake cover 104 from being locally bent downward, the load is concentrated on the support surface of the dash panel 106 of the pair of side walls 128 and 126, so that the pair of side walls 128 , 126 are inclined in the vehicle width direction. In this manner, the intake cover 104 can be easily deformed so as to bend in the vertical direction.

Further, since the inclined portions 176, 186 of the front edges 174, 184 of the pair of side walls 128, 126 are free ends, the inclined portions 176, 186 can be displaced in the vehicle width direction.

FIG. 5 is a view showing each cross section of the intake cover 104 of FIG. 4(b). 5(a) and 5(b) are diagrams showing the DD cross section and the EE cross section of the intake cover 104 of FIG. 4(b), respectively. FIG. 6 is a diagram showing a state in which the intake cover 104 of FIG. 3 is viewed from another direction. 6(a), 6(b), and 6(c) are a bottom view, a top view, and a rear view of the intake cover 104, respectively.

As shown in FIG. 5A, the pair of support portions 132 and 134 are arranged on both sides of the connecting portion 130 in the vehicle width direction, and are inclined from the upper wall 124 toward the connecting portion 130 so as to approach each other. . The connecting portion 130 is overlapped with the waterproof wall 120 of the intake portion 102 shown in FIG. Further, as shown in FIG. 5B, a first sealing member 218 and a second sealing member 220 are provided on the trailing portion 216 of the upper wall 124 of the intake cover 104 and the rear wall 210, respectively.

As a result, the gaps between the outer rear portion of the intake cover 104 and other members such as the dash panel 102 can be sealed with the respective sealing members 218 and 220. A repulsive force (reaction force) of the sealing members 218 and 220 acts. This repulsive force is transmitted to the intake portion 102 via the pair of support portions 132 , 134 of the intake cover 104 , the connecting portion 130 and the fastening member 136 . As a result, even if there are few connection points between other members such as dash panel 106 and air intake portion 102, the gap can be easily sealed.

In addition, the second sealing member 220 is configured such that the lower surface of the first flange 138 It is arranged so as to be continuous with the first side wall 126 and the rear wall 210 (see FIG. 6(a)), thereby enhancing the water cut-off property. Furthermore, in the intake cover 104, the first flange 138 is connected to the rear portion of the first side wall 126 via the vertical wall portion 149, and further connected to the second flange 140 via the rear wall portion 210 (FIG. 6B). reference). Therefore, in the intake cover 104, the reaction force of the second sealing member 220 can be dispersedly received by the first flange 138 and the second flange 140. Therefore, even if the number of fastening points is small, the second sealing member 220 can effectively stop the force. It is possible to increase the water resistance. The second sealing member 220 is arranged so as to extend over the second flange 140 (see FIG. 6(c)).

Further, as shown in FIG. 5A, since a gap 159 is formed between the pair of support portions 132 and 134, when an external force is applied to the intake cover 104 from above, the pair of support portions 132 and 134 Each is easily deformed in the inclined direction.

Furthermore, as shown in FIG. 5(b), a bulging portion 212 that bulges upward in the vehicle width direction is provided at the rear portion of the upper wall 124, so that the outside air (see arrow F in the drawing) is drawn into the bulging portion. From 212 it can be guided along the back wall 210 .

For this reason, in the intake cover 104, when a load is applied from above while the external air is efficiently guided to the intake portion 102, the upper wall 124 is moved from the rising portion 214 arranged behind the inclined portions 176 and 186 as a starting point. can be urged to bend and deform in the vertical direction.

5B, the intake cover 104 has an angle θa between the rising portion 214 of the upper wall 124 and its front portion, an angle θb between the rising portion 214 and the falling portion 216, and an angle θb between the falling portion 216 and the rear portion 216. Both the angle θc formed by the wall 210 and the angle θd formed between the rear wall 210 and the dash panel 106 are obtuse angles. In this manner, the intake cover 104 forms an obtuse angle at the angles θa, θb, θc, and θd, thereby forming an elliptical airflow as shown by arrow F when outside air is introduced from the front. Therefore, intake can be efficiently performed. Further, when the angle θa is 120° or more, the air along the front portion is not separated and is easily introduced into the rising portion 214, and intake can be performed more efficiently.

Note that the rising portion 214 may rise in an arc shape so as to have a predetermined radius of curvature when viewed from the side. The falling portion 216 may fall in an arc shape so as to have a predetermined radius of curvature when viewed from the side.

The support portion 132 is formed such that its cross-sectional area decreases from the upper wall 124 toward the connecting portion 130 as shown in FIG. 5(b). In addition, as shown in FIG. 3A, the cross-sectional area of the support portion 134 also decreases from the upper wall 124 toward the connecting portion 130. As shown in FIG.

As a result, when the intake cover 104 receives an external force from above and impact energy is transmitted downward from above the support portions 132 and 134, local stress concentration occurs within the support portions 132 and 134. can be avoided. Therefore, unintended deformation of the support portions 132 and 134 does not occur, and the support portions 132 and 134 can be deformed in an inclined direction.

As shown in FIG. 5B, the ribs 154 of the support portion 132 and the connecting portion 130 have a substantially triangular shape as a whole, with the dimension in the front-rear direction decreasing downward. In addition, weakened portions 224 and 226 that are more fragile than the periphery are formed in the connection regions 168 and 170 shown in FIG. 3(a). The fragile portions 224 and 226 are thin in the vehicle width direction and extend in the vehicle front-rear direction.

A bent portion 228 is formed in the connection region 160 of the support portion 132 as shown in FIG. 5(b). The bent portion 228 is thin in the vehicle width direction and extends in the vehicle front-rear direction to promote deformation of the support portion 132 in the vehicle width direction. As a result, the support portion 132 will not break until it is deformed and sufficiently inclined. Instead of the fragile portions 164, 166, 224, 226 (see FIG. 3(a)) and the bent portion 228, a through hole is provided through a part of the pair of support portions 132, 134 in the vehicle width direction. Or you may form a notch.

Further, as shown in FIG. 5(a), the upper wall 124 is slanted so that the height is different in the vehicle width direction. Furthermore, the support portion 132 is connected to the upper wall 124 at a position higher than the support portion 134 . As a result, when the pair of support portions 132 and 134 receives a load from above, the support portion 132 connected to the upper wall 124 at a high position is bent at the bending portion 228, and the load is transmitted to the support portion 134 side. By doing so, both of the pair of support portions 132 and 134 can be encouraged to deform.

Here, in a vehicle, the closer to the center of the vehicle, the easier it is to introduce air from the front, while the closer to the outside of the vehicle, the more air escapes to the outside of the vehicle. Therefore, in the intake cover 104, as shown in FIG. 6(a), the rising portion 214 and the falling portion 216 of the bulging portion 212 are inclined so that they are located forward toward the center of the vehicle (right side in the drawing). ing. As a result, the air can be guided along the inclined direction of the rising portion 214 and the falling portion 216 , making it easier to guide the air to the entire intake port 108 of the dash panel 108 .

Further, as shown in FIG. 6A, the pair of support portions 132 and 134 are positioned at the front end position (see G in the figure) and the rear end position (see H in the figure) of the rising portion 214. is provided in a region 230 between With this configuration, when the intake cover 104 bends starting from the obliquely inclined bulging portion 212, even if an external force acts on a position displaced from the center of the upper wall 124, the pair of support portions 132 and 134 will not be bent. It becomes easier to apply an external force to

6(a) and 6(b), the first side wall 126 has a smaller dimension in the longitudinal direction of the vehicle than the second side wall 128, as shown in FIGS. 3(b) and 6(c). The vertical dimension is long. Accordingly, when the dash panel 106 is inclined so as to curve forward toward the center in the vehicle width direction, the first side wall 126 is smaller than the second side wall 128 in the vehicle front-rear direction. 126 , 128 may be positioned along the slope of dash panel 106 . Therefore, it is possible to avoid forming a dead space on the dash panel 106 with the intake cover 104 fixed to the dash panel 106 .

Further, the second side wall 128 is longer in the longitudinal direction of the vehicle and smaller in the vertical direction than the first side wall 126 . Therefore, when an external force is applied to the upper wall 124 of the intake cover 104 from above, the reaction force difference between the pair of side walls 126 and 128 is reduced, and the upper wall 124 bends in the vertical direction starting from the center in the vehicle width direction. can be made easier.

FIG. 7 is a diagram showing a case where an external force (see arrow I in the drawing) is applied from above to the intake cover 104 of FIG. 7(a) and 7(b) are diagrams showing a state in which the intake cover 104 is deformed by receiving an external force from above. FIG. 7(c) is a diagram showing a state in which the intake cover 104A of the comparative example is deformed.

The pair of support portions 132 and 134 of the intake cover 104 support the connecting portion 130 as shown in FIG. Therefore, even if waterproof wall 120 of intake portion 102 is vertically connected by connecting portion 130 in the flow path of intake cover 104, deformation of intake cover 104 can be promoted.

That is, when the intake cover 104 receives an external force (see arrow I) from above, the support portions 132 and 134 are likely to be deformed in an inclined direction. A dashed line J in FIG. 7A indicates the shape of the intake cover 104 before deformation.

Further, connection regions 160, 162 between the pair of support portions 132, 134 and the pair of ribs 154, 156 shown in FIG. Rigidity is lower than 170.

As a result, when the intake cover 104 receives an external force indicated by an arrow I in FIG. 7A, the support portions 132 and 134 are deformed in the inclined direction, and the side walls 126 and 128 are further displaced in the vehicle width direction. As a result, the upper wall 124 is deformed downward. The side walls 126 and 128 are deformed so that the upper side approaches each other (see arrows K and M), and the lower side deforms so as to move away from each other (see arrows L and N), so that they are deformed to open in a so-called V shape. do.

Then, the connection region 160 (see FIG. 3(a)) between the support portion 132 and the rib 154 of the connecting portion 130 is broken as shown in FIG. 7(a). In this way, in the intake cover 104, the connection regions 160, 162 between the support portions 132, 134 and the connecting portion 130 are broken or the support portions 132, 134 and their surroundings are deformed by the impact energy when the intake cover 104 receives an external force. It can be used as energy to Therefore, the intake cover 104 can efficiently absorb the impact when receiving an external force from above.

The intake cover 104A of the modification shown in FIG. 7(c) has a cutout at the rear side of the first flange 138A projecting from the side wall 126A, and further has the lower surface portion 222 connected to the side wall 128A and the first flange 140A. It differs from the intake cover 104 in that it does not.

Even with this intake cover 138A, the support portions 132 and 134 support the connecting portion 130 and extend and incline in a direction not perpendicular to the upper wall 124, so that when an external force is applied from above, It can absorb impact efficiently.

3(b), the intake cover 104 has a first raised portion 150 in which the first flange 138 is raised upward in correspondence with the raised shape 114 of the dash panel 106 (see FIG. 1(a)). Further, a first fixing point 142 is set on the outer side of the first raised portion 150 in the vehicle width direction.

Therefore, the air intake cover 104 can contact the dash panel 106 and the first raised portion 150 in the vehicle width direction. Then, as shown in FIG. 7A, when a load is received from above the upper wall 124 and a shear force (load in the vehicle width direction) is generated to displace the lower end of the first side wall 126 outward in the vehicle width direction, Displacement of the side wall 126 can be received by the raised feature 114 of the dash panel 106 via the first raised portion 150 . Also, it is possible to avoid concentration of this shearing force on the first fixing point 142 .

Further, in the intake cover 104, by providing the second raised portion 151 between the first fixed point 142 and the first side wall 126, the second raised portion 151 is bent in the vehicle width direction when a load is applied from above. Therefore, the first side wall 126 can be easily inclined in the vehicle width direction. In addition, since the second raised portion 152 is formed with a plurality of bending points, stress concentrates on the bending points and the second protruding portion 152 is likely to be deformed. In addition, although the second raised portion 151 bulges upward, it is not limited to this, and may bulge downward.

Further, as shown in FIG. 4B, the lower surface portion 222 projects in the vehicle width direction from the lower edge 202 of the second side wall 128, extends toward the front side of the vehicle from the second flange 140, and is provided with a fixing point. not Therefore, the lower surface portion 222 becomes a free end with respect to the dash panel 106 . Accordingly, when a load is applied from above the upper wall 124, the periphery of the second side wall 128 including the lower surface portion 222 bends to absorb the load. 132 and 134 can be prevented from falling sideways.

Further, the second sealing member 220 provided on the rear wall 210 of the intake cover 104 extends to the first flange 138 and further extends from the second flange 140 to the lower surface portion 222 as shown in FIG. are placed. As a result, the repulsive force of the second sealing member 220 can be easily received by the first fixing points 142 and the second fixing points 144, thereby enhancing the waterproofness. Furthermore, the shear force generated when the top wall 124 receives a load from above can be released to the vertical wall 116 (see FIG. 1(a)) of the dash panel 106 via the second sealing member 220. FIG.

FIG. 8 is a diagram schematically showing another modification of the intake cover 104 of FIG. 5(a). The intake cover 104B shown in FIG. 8A has a pair of support portions 132 and 134A that are parallel to each other and inclined with respect to the upper wall 124 . Even with such a configuration, when an external force is applied from above, the support portions 132 and 134A are likely to be deformed in the inclined direction. can promote the transformation of

The intake cover 104C shown in FIG. 8B has a pair of support portions 132 and 134B, in which the support portion 132 is inclined with respect to the upper wall 124, and the support portion 134B is perpendicular to the upper wall 124. extends to Even with such a configuration, when an external force is applied from above, the support portion 132 of the support portions 132 and 134B is more likely to be deformed in the inclined direction, thus promoting the deformation of the intake cover 104C.

In addition, the support portions 132, 134, and 134A extend in a direction that is not perpendicular to the upper wall 124. It may have a portion or vertical portion extending in the direction of .

If at least one of the pair of support portions 132, 134, 132, 134A and 132, 134B is inclined with respect to the upper wall 124, the pair of support portions 132, 134 are not only arranged side by side in the vehicle width direction. , may be arranged side by side in the longitudinal direction of the vehicle.

As shown in FIG. 5A, the intake cover 104 has an upper wall 124, a pair of side walls 126 and 128, and a lower surface portion 222 continuous to the first flange 138 and the second flange 140. It has a convex hat shape. On the other hand, the intake cover 104D shown in FIG. 8(c) is upwardly convex due to the upper wall 124, the first side wall 126 and the second side wall 128B, and protrudes from the second side wall 128B toward the upper wall 124 side. It has an inner flange 232 .

The intake cover 104E shown in FIG. 8(d) has an inner flange 234 which is upwardly convex due to the top wall 124, the first side wall 126B and the second side wall 128B, and protrudes from the first side wall 126B toward the top wall 124 side. . Since the intake covers 104D and 104E have no bottom surface (lower wall) and are open at the bottom and have an upward convex shape, they are easily deformed when an external force is applied to the upper wall 124 from above. It is easy to absorb the impact energy caused by

The connecting portion 130 of the air intake cover 104 is connected to the waterproof wall 120 of the air intake portion 102 arranged below the upper wall 124, but is not limited to this. Further, if the intake cover 104 has a lower wall that defines the lower side of the flow path, the connecting portion 130 may be connected to the lower wall instead of the intake portion 102 or the dash panel 106 .

Also, in the intake cover 104, as shown in FIGS. The included regions 194, 196 facilitate the introduction of outside air. However, the present invention is not limited to this, and the side walls 128 and 126 may not be provided with the regions 194 and 196 so that the top wall 124 is more easily deformed when an external force is applied from above.

Furthermore, since the pair of support portions 132 and 134 are in a state of being opened in an inverted V shape, even if an external force received from above acts on one side or the other side of the intake cover 104 in a predetermined direction, The pair of support portions 132 and 134 are easily deformed in an inclined direction, and the connection regions 160 and 162 between the support portions 132 and 134 and the connecting portion 130 are easily broken.

Further, in the intake cover 104, as shown in FIG. located behind. Since the first fixing point 142 and the second fixing point 144 are arranged at different positions in the front-rear direction in this way, when an external force is applied to the intake cover 108 from above, the first side wall 126 or the second side wall 128 is twisted. It is possible to promote deformation and facilitate displacement in the vehicle width direction.

Furthermore, as shown in FIG. 1(b), the second fixing point 144 of the second flange 140 and the third fixing point 152 provided for fixing the air conditioning unit 119 to the dash panel 106 are overlapped, so that the dash panel The number of fixing points required to secure the intake cover 104 and the air conditioning unit 119 to 106 can be reduced.

Further, by overlapping the second fixing point 144 and the third fixing point 152 and passing a predetermined fastening member 148 therethrough to fix the air intake cover 104 and the air conditioning unit 119 to the dash panel 106, can increase the rigidity of As a result, when the intake cover 104 receives an external force, the overlapped fixed points are less likely to be displaced, so that the upper wall 124 and the pair of side walls 126 and 128 of the intake cover 104 can be easily deformed.

In the intake cover 104, the first sealing member 218 is provided on the falling portion 216, and the rear side of the pair of support portions 132 and 134 is inclined along the rising portion 216 as shown in FIG. 5(a). are doing. Therefore, the repulsive force of the first sealing member 218 is transmitted from the falling portion 216 of the upper wall portion 124 to the rising portion 214 . This repulsive force is reliably transmitted to a pair of supporting portions 132 and 134 inclined along rising portion 216 , and further transmitted to intake portion 102 via connecting portion 130 and fastening member 136 . As a result, even if the number of connecting points between other members such as dash panel 106 and air intake portion 102 is small, the gap can be more easily sealed.

The intake cover 104 also has an upper flange 236 and outer flanges 238, 240 shown in FIG. The upper flange 236 projects upward from the front end 182 of the upper wall 124 (see FIG. 4(a)). The outer flanges 238 , 240 project outward in the vehicle width direction from the pair of side walls 126 , 128 . This makes it easier to guide outside air along the upper flange 236 and the outer flanges 238 and 240 toward the upper wall 124 and the pair of side walls 126 and 128 .

Although the intake cover 104 is fixed to the dash panel 106 in order to form a flow path for guiding outside air to the intake portion 102, the structure of the intake cover 104 is not limited to this, and can be appropriately installed in the vehicle. You may apply to a resin cover. Here, the resin cover can be used, for example, as a protective cover for protecting vehicle-mounted parts and electrical parts. Further, the resin cover may have the same configuration as the intake cover 104, such as providing a bottom wall.

Here, the configuration of the resin cover will be described with reference to FIG. 3(a). The resin cover includes a pair of side walls 126, 128 spaced apart in a predetermined direction and an upper wall 124 as an outer wall connecting the pair of side walls 126, 128. The pair of side walls 126, 128 and the upper wall 124 are molded of resin. It is mounted on the vehicle by partitioning the space surrounded by.

The resin cover further has a connecting portion 130 connected to a predetermined lower member below the upper wall 124 and a pair of support portions 132 and 134 extending from the upper wall 124 and supporting the connecting portion 130 . The support portions 132 and 134 are inclined so as to approach the center of the upper wall 124 from the upper wall 124 toward the connecting portion 130 . The end portions of the support portions 132 and 134 on the connecting portion 130 side have lower rigidity than the end portions of the support portions 132 and 134 on the upper wall 124 side.

As a result, when the upper wall 124 of the resin cover receives an external force that deforms toward the inside of the vehicle, for example, the support portions 132 and 134 are inclined in the direction in which they are inclined, ie, the closer they are to the center of the upper wall 124 toward the connecting portion 130 . It is easy to deform in the direction Therefore, the impact energy associated with the external force can be used as energy for deforming the support portions 132 and 134 and their periphery, or for breaking the ends of the support portions 132 and 134 on the connecting portion 130 side. Therefore, the resin cover can efficiently absorb the impact when the upper wall 124 receives an external force that deforms.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is obvious that a person skilled in the art can conceive of various modifications or modifications within the scope described in the claims, and these also belong to the technical scope of the present invention. Understood.
