Description

  The present invention relates to a cowl top cover having an impact absorbing structure in an automobile that is excellent in pedestrian protection performance. Note that the front-rear direction, the vertical direction, and the width direction of the vehicle body used in the present invention are directions when the vehicle is directed from the rear of the vehicle body toward the forward direction of the vehicle with reference to the forward direction in which the vehicle advances straight.

  When an obstacle or the like rides on the bonnet when an obstacle or the like collides when the vehicle travels, the bonnet bends downward due to an impact from the collision object. At this time, if a highly rigid vehicle-mounted component or the like is disposed below the bonnet, the collision object strongly collides with the vehicle-mounted component or the like while bending the bonnet. In order to prevent this, it is demanded that a cowl panel or a cowl top cover be provided with an impact absorbing structure that can relieve an impact force from a collision object.

  As a cowl top cover having an impact absorbing structure, a vehicle body structure described in Patent Document 1, a vehicle cowl louver structure described in Patent Document 2, and the like have been proposed. The vehicle body structure described in Patent Document 1 is a conventional example 1 in the present invention. FIG. 8 is a cross-sectional view of the vicinity of the front portion of a cowl top cover (in Patent Document 1, described as a deck garnish). Show. FIG. 9 is a cross-sectional view of the cowl louver structure described in Patent Document 2 in the vicinity of the front portion of the cowl top cover when a load of deposits is applied to the blindfold member. Is shown.

  As shown in FIG. 8, the cowl top cover 41 is a first member extending in the vertical direction of the vehicle body between the cowl top panel 43 (described as an outfit deck in Patent Document 1) and the bonnet 44. The first portion 46 and the second portion 47 extending from the upper end of the first portion 46 toward the front window 42 are provided.

  Thin portions 48, 49, 50 are formed in the first portion 46 over the entire vehicle width direction, and thin portions 52 are also formed in the second portion 47 over the entire vehicle width direction. The thin portions 48, 49, and 50 are configured as first fragile portions, and the thin portion 52 is configured as a second fragile portion. The cowl top cover 41 has a first fragile portion and a second fragile portion, but is set so that the first fragile portion and the second fragile portion are not deformed at a load (for example, 0.3 kN) or less. Has been.

  When the pedestrian's head or the like comes into contact with the rear end portion of the bonnet 44 due to the collision and an impact force G from above is applied to the bonnet 44, the load force G is applied to the cowl top cover 41 via the seal member 45. Will be transmitted to. The cowl top cover 41 to which the impact force G is applied is configured to absorb impact energy by first deforming the thin-walled portions 48, 49, 50 configured as the first fragile portions. The impact energy that could not be absorbed by the deformation of the thin-walled portions 48, 49, 50 can be absorbed when the thin-walled portion 52 configured as the second weakened portion is deformed or broken.

  That is, in the invention of Patent Document 1, a part of the wall thickness of the cowl top cover 41 is locally thinned to such an extent that there is no practical problem in rigidity, and the thinned first weakened part and The second fragile portion is deformed to absorb impact energy when a pedestrian collides.

  In the vehicular cowl louver structure described in Patent Document 2, as shown in FIG. 9, a cowl 62 is disposed on the rear side of the hood 61 and the engine room 60 along the vehicle width direction. The cowl 62 includes a cowl louver 65 that constitutes an upper surface on the front side of the vehicle body, a cowl upper panel 64 that constitutes an upper surface on the rear side of the vehicle body, and a cowl inner panel 63 that constitutes a lower surface. The opened front portion of the cowl inner panel 63 is covered with a cowl louver 65, and the rear portion of the vehicle is covered with a cowl upper panel 64.

  A blindfold member 66 extending along the vehicle width direction is disposed between the vehicle rear side end portion of the hood 61 and the cowl louver 65. The blindfold member 66 is made of an elastically deformable rubber-based material having a lower rigidity than the resin cowl louver 65, and is in close contact with the hood 61 and the cowl louver 65 by being elastically deformed as a whole.

  The blindfold member 66 has a plate-like attachment portion 67 formed on the upper portion, and the vehicle front side portion of the attachment portion 67 is attached to the shelf portion of the hood inner panel 61b via a clip 71. The vehicle rear side portion of the mounting portion 67 is inclined upward toward the vehicle rear side, and is formed on a joint portion of the hood 61 between the hood outer panel 61a and the hood inner panel 61b (the vehicle rear end portion of the hood 61). The vehicle rear side end portion 67a is in contact with the portion 61c.

  The blindfold member 66 is formed with a leg portion 68 that extends downward from a lower surface on the vehicle rear side slightly from the center of the attachment portion 67. The tip end side of the leg portion 68 is divided into two parts, a first leg portion 69 and a second leg portion 70. As the first leg portion 69 moves downward, the distal end side curves toward the rear side of the vehicle and contacts the cowl louver 65, and as the second leg portion 70 moves downward, the distal end side curves toward the front side of the vehicle and contacts the cowl louver 65. ing.

  When a collision body (not shown) collides with the vehicle rear side end of the hood 61 and an impact from above is applied to the vehicle rear side end of the hood 61, the vehicle rear end of the hood 61 is deformed to sink downward. To do. Then, a load is applied to the blindfold member 66, and the blindfold member 66 is elastically deformed. At this time, since the blindfold member 66 is made of a rubber-based material, the first leg portion 69 and the second leg portion 70 can be easily opened and elastically deformed. That is, the deformation load is small. Further, the blindfold member 66 can be crushed until the attachment portion 67 contacts the first leg portion 69 and the second leg portion 70, and has a configuration in which there is almost no crushed residue.

  In the vehicle cowl louver structure described in Patent Document 2, in addition to the configuration that absorbs the impact applied to the vehicle rear side end portion of the hood 61 from the upper side, the first leg portion 69 of the blindfold member 66 has snow on the vehicle rear side. Even when a deposit S such as the above is deposited (stacked) and a load in the direction along the inclination of the cowl louver 65 is applied to the blindfold member 66 as indicated by an arrow Y, this load is applied by the second leg 70. It has a structure that can be stretched and supported. In addition, even if the deposit S such as snow is accumulated, the deformation of the blindfold member 66 such as the first leg 69 being reversed can be suppressed or prevented.

Japanese Patent Laying-Open No. 2005-306086 JP 2008-284882 A

  In the invention described in Patent Document 1, when an impact force is applied to the bonnet, the first fragile portion and the second fragile portion formed on the cowl top cover 41 are deformed, so that when a pedestrian collides. It is configured to absorb impact energy. However, when a load from the direction along the inclination of the front window 42 is applied to the second portion 47 due to accumulation of snow or ice or the like on the cowl top cover 41, it is configured as a second weakened portion. The thin-walled portion 52 is deformed, or in the worst case, it is broken.

  In particular, when snow or ice removed from the front window 42 by the wiper accumulates on the cowl top cover 41, the snow or ice is pressed from one to the next by the operation of the wiper. Therefore, if the rigidity of the thin-walled portion 52 configured as the second fragile portion cannot withstand the pressing force caused by snow or ice, it will be deformed or broken.

  Further, when the snow or ice accumulated on the cowl top cover 41 is removed by the scraper, even if an excessive pressing force is applied to the second portion 47 from the scraper, the thin portion 52 is deformed or broken. It will end up. If the thin-walled portion 52 is deformed or broken, in the worst case, the engaging portion formed on the rear end side of the second portion 47 may fall off from the front window 42. .

  That is, when the cowl top cover 41 is deformed beyond the lap amount at the engaging portion between the front window 42 and the cowl top cover 41, the cowl top cover 41 falls off the front window 42.

  In the invention described in Patent Document 2, a deposit S such as snow or ice accumulates (accumulates) on the vehicle rear side of the first leg portion 69 of the blindfold member 66, and a load is applied from the direction indicated by the arrow Y. Even if it is applied to the blindfold member 66, this load can be supported by the second leg 70 stretching. However, since the blindfold member 66 is made of a rubber-based material and elastically deforms, when a load larger than the load that can be supported by the tension of the second leg portion 70 is applied to the blindfold member 66, the first leg The distal end 69A of the portion 69 and the distal end 70A of the second leg portion 70 may come out of contact with the cowl louver 65, or the blindfold member 66 may be bent or broken from the middle.

Then, the deposit S such as snow or ice flows between the recess of the cowl louver 65 and the hood 61. And, by the deposit S flowing between the recess of the cowl louver 65 and the hood 61, the hood 61 whose rotation is locked is applied with a pressing force to open upward, and the cowl louver 65 is Thus, a pressing force that presses the cowl louver 65 toward the front side of the vehicle or a pressing force that causes the cowl louver 65 to project downward and deform is applied.
In this manner, the cowl louver 65 is deformed by these pressing forces acting on the cowl louver 65 and falls out of the engaged state with the windshield 72.

  The present invention can maintain the shock absorbing performance of the cowl top cover when an impact force is applied to the bonnet, and deposits such as snow and ice accumulate on the cowl top cover. In addition, even when a pressing force is applied to the front side of the vehicle, the cowl top cover can be prevented from falling out of the engaged state with the windshield, and the pressing force has returned to a state where it has stopped working. In some cases, it is an object to provide a cowl top cover that can sufficiently function as a cowl top cover.

The object of the present invention can be achieved by the cowl top cover described in claims 1 to 4.
That is, in the present invention, the lower part of the hood that covers the upper part of the cowl top panel extending in the vehicle width direction and covers the upper opening of the front compartment of the vehicle along the lower end part of the windshield disposed at the front part of the vehicle body In the cowl top cover, the front end of the cowl top cover is fixed to the cowl top panel, and an engaging portion formed at the rear end engages with the windshield. The cover body portion between the end portion and the rear end portion has a protruding portion protruding upward in the front-rear direction of the vehicle body in at least one place in the vehicle width direction, and on the back side of the protruding portion, At least one or more ribs formed along the front-rear direction of the vehicle body are provided, and the ribs or the protrusions facing the end surfaces of the ribs in the front-rear direction of the vehicle body are provided. Between the surfaces, and the most important feature that the slit-like gaps downward from the back surface side of the projecting portion is formed.

In addition, the main feature of the present invention is that at least one end face across the gap is configured as a face extending in the vehicle width direction.
Furthermore, the present invention is characterized in that the surface extending in the vehicle width direction is formed wider than the width dimension of the rib.
Furthermore, the main feature of the present invention is that a cushioning material is provided in the gap.

  In the present invention, at least one or more ribs are provided along the front-rear direction of the vehicle body on the back surface side of the protrusion provided on the cover main body. In addition, a slit-like gap extending downward from the back surface side of the protrusion is formed on the rib or between the end surface of the rib and the back surface of the protrusion that opposes in the front-rear direction of the vehicle body.

  With this configuration, if a deposit such as snow or ice accumulates on the cowl top cover, and if a further pressing force is applied to the accumulated snow or ice deposit on the front side of the vehicle, the cover The main body is elastically deformed in the direction of narrowing the slit-shaped gap. However, the elastic deformation of the cover main body is a deformation until the slit-like gap disappears. When the slit-like gap disappears, the elastic deformation of the cover main body is restricted by the rib.

  The amount of deformation of the cover main body is smaller than the amount of wrap in which the engaging portion formed at the rear end of the cover main body is engaged with the windshield. Therefore, even if the cover main body is elastically deformed by the gap, the cover main body can be prevented from falling off the windshield.

  In this way, even if the load of snow or ice pushing by the wiper or the impact force during ice breaking by the scraper acts on the cowl top cover, the engagement between the cover body and the windshield is released. The cover main body can be prevented from falling off the windshield.

  Also, when removing snow or ice by freezing with a scraper etc., a relatively strong impact force is transmitted to the cowl top cover, but at that time, the cowl top cover is elastically deformed by the gap in the protruding part. It will be. Further, the cushioning effect due to the elastic deformation of the cowl top cover can alleviate the impact force transmitted to the parts that are holding the cowl top cover, and can prevent the parts from being damaged.

  In addition, the configuration of the protruding portion does not adversely affect the impact absorbing performance of the cowl top cover when an impact force is applied to the bonnet. That is, when an impact force is applied on the bonnet, the projecting portion is crushed by the bonnet. And as a protrusion part, a slit-shaped clearance gap will be crushed in the direction which spreads in fan shape, and the impact force added on the bonnet can be relieve | moderated by the deformation | transformation of this protrusion part.

  As described above, the protrusions and the ribs are not configured to counteract the impact force applied to the bonnet, but are configured to absorb the impact force. The shock absorbing performance of the cowl top cover when an impact force is applied to the bonnet can be maintained as it is even in the cowl top cover that constitutes the protruding portion.

  In addition, even if a deposit such as snow or ice accumulates on the cowl top cover, and the pressing force toward the front side of the vehicle is further applied to the accumulated snow or ice deposit, This pressing force can be overcome by the ribs that have been eliminated. In addition, when the pressing force toward the front side of the vehicle no longer acts, the cowl top cover can be elastically returned to a state where a slit-like gap is formed by an elastic force.

  The required number of protrusions provided in at least one place in the vehicle width direction can be provided in a desired number in a desired portion in the vehicle width direction. The number of protrusions to be provided is the number of parts that are subject to a relatively strong impact force when removing snow by freezing with a scraper or the like, and the snow or ice that has fallen on the cowl top cover is compressed by the wiper operation. It can be provided in the area where it goes.

  In the present invention, by forming the shape on at least one end face across the gap as a surface extending in the vehicle width direction, the contact with the end face of the rib is good when the slit-like gap disappears Will be done. And by making the width of the surface extended in the vehicle width direction wider than the width dimension of the rib, the contact with the end face of the rib can be performed well when the slit-like gap disappears. .

  Also, when removing snow and ice by freezing with a scraper etc., a relatively strong impact force is transmitted to the cowl top cover, but by installing a cushioning material in the slit-shaped gap, the cowl top cover In addition to the cushion effect due to elastic deformation, the cushion effect due to the cushioning material can be further provided.

  Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. As the cowl top cover according to the present invention, in addition to the shape and configuration described below, any shape and configuration that can solve the problems of the present invention can be adopted. is there. For this reason, this invention is not limited to the Example demonstrated below, A various change is possible.

  As shown in the perspective view of the front portion of the vehicle body in FIG. 1, the lower edge of the windshield 3 is supported by the cowl top cover 2 as shown in FIG. Further, as shown in FIG. 1, the upper portion of the front compartment forming an engine room (not shown) is covered with a bonnet 4 so that the rear end side or the front end side of the bonnet 4 can be opened. The bonnet 4 is rotatably supported at the front end portion or the rear end portion.

  A wiper 5 is provided at the lower part of the windshield 3 to maintain a good visibility of the windshield 3 covered with rain, snow, etc. The motor that drives the wiper 5 is covered by the cowl top cover 2. It is stored in the space.

  As shown in FIG. 2, the cover body portion 10 of the cowl top cover 2 has a front end portion 10a fixed to the cowl top panel 7, and an engagement portion 11 formed on the rear end portion 10b has a predetermined lap. The amount is engaged with the lower edge of the windshield 3.

  The cowl top panel 7 and the cowl top cover 2 can be made of a resin material or a metal material. A bonnet reinforcement 4a is attached to the back side of the bonnet 4. When the bonnet 4 is closed, the bonnet reinforcement 4a is a seal provided on the front end side of the cover body 10 in the cowl top cover 2. The member 6 is in pressure contact. The seal member 6 prevents rainwater and the like from entering the front compartment.

  A front end portion 10 a extending downward is formed on the front end side of the cover body portion 10, and the lower surface side of the front end portion 10 a is supported by the cowl top panel 7. The cover body 10 is provided with protrusions 12 protruding upward in the front-rear direction of the vehicle body 1 at at least one location in the vehicle width direction. The protrusion 12 can be formed integrally with the cover body 10 or can be formed separately.

  In the following description, a configuration example in which the protrusion 12 is formed integrally with the cover main body 10 will be described. When the protruding portion 12 is formed separately from the cover main body portion 10, the protruding portion 12 formed separately can be attached to the cover main body portion 10 using appropriate fixing means.

  Ribs 15 formed along the front-rear direction of the vehicle body 1 are provided on the back surface side of the protruding portion 12. The protrusions 12 can be provided at least at one location in the vehicle width direction. Further, at least one or more ribs 15 formed in one protrusion 12 can be formed in the vehicle width direction.

  As shown in FIG. 2, the rib 15 can be configured to be continuous with the back side region of the cover main body 10 other than the back side of the protruding portion 12. In addition, a slit-like gap 16 is formed in the single rib 15 from the back surface side of the top portion 12a of the protruding portion 12 toward the lower side. That is, the end surfaces 15a and 15b of the rib 15 with the gap 16 in between are separated from each other. The slit-shaped gap 16 is not limited to a shape that faces downward from the back surface side of the top portion 12a of the protruding portion 12, but is configured to have a shape that faces downward from the back surface side of the protruding portion 12. You can also.

  As shown in FIG. 3, when a pedestrian who has collided with the vehicle rides on the hood 4, an impact force F from above is applied to the hood 4 by the pedestrian as the collision object 20. At this time, the bonnet 4 narrows the space between the bonnet reinforcement 4a provided on the back surface side and compresses the seal member 6 to displace the front end side of the cowl top cover 2 downward.

  Then, the bonnet reinforcement 4a in contact with the top portion 12a of the protruding portion 12 of the cover main body portion 10 contacts the top portion 12a of the protruding portion 12 and presses the protruding portion 12 while further descending. The protrusion 12 pressed by the bonnet reinforcement 4a is crushed so that the slit-shaped gap 16 spreads out in a fan shape around the top 12a.

  Further, the front vertical wall 10c extending downward from the front end side of the cover main body 10 is also pressed by the bonnet reinforcement 4a and tends to be displaced downward. However, since the downward displacement of the lower end portion of the front vertical wall 10c is restricted while being in contact with the cowl top panel 7, the weakened portion 14 formed on the front vertical wall 10c is deformed or broken. However, the front vertical wall 10c is deformed.

  By deforming the bonnet 4, the seal member 6, and the cover main body 10 in this way, the impact force applied on the bonnet 4 can be relaxed and absorbed. And the damage with respect to the pedestrian who got on the bonnet 4 can be decreased.

  As shown in FIG. 4, when a deposit 21 such as snow or ice accumulates between the protrusion 12 of the cover body 10 and the windshield 3, a load acts in the direction of crushing the gap 16 of the protrusion 12. Will do.

  In particular, when the snow removed from the windshield 3 by the wiper 5 accumulates on the cowl top cover 2, the snow is pressed toward the protrusion 12 of the cover main body 10 one after another by the operation of the wiper. It will be. That is, the load from the wiper indicated by the arrow N2 in FIG.

  In addition, when the scraper 24 is used to remove snow and ice deposits 21 accumulated on the windshield 3 and the cowl top cover 2, excessive pressing from the scraper 24 to the protrusion 12 is also possible. Pressure N1 may act.

  When such a load N2 from the wiper or a pressing force N1 from the scraper 24 acts on the protruding portion 12, the protruding portion 12 deforms in a direction in which the gap 16 in the rib 15 formed on the back surface side of the protruding portion 12 is eliminated. It will follow. That is, the protrusion 12 is elastically deformed in a direction in which the gap 16 is eliminated. Then, the end face 15a sandwiching the gap 16 in the rib 15 and the end face 15b come into contact with each other, so that the protrusion 12 can be prevented from being deformed over a certain amount.

  As described above, since the elastic deformation amount of the protrusion 12 can be regulated as the amount of the gap 16, the engagement portion 11 provided on the rear end portion 10b of the cover body portion 10 and the windshield 3 are engaged. The protrusion 12 is elastically deformed over the amount of lap when it is joined, that is, the rear end 10b of the cover body 10 is moved relative to the windshield 3. Can be prevented.

  Thus, even when the load N2 and the pressing force N1 from the wiper act on the protruding portion 12, the elastic deformation amount of the protruding portion 12 can be regulated, and the cover main body portion 10 can be controlled by the windshield 3. Can be prevented from falling off. When the load N2 and the pressing force N1 from the wiper are no longer applied to the protrusion 12, the protrusion 12 is restored from the elastically deformed state to the state where the gap 16 is formed between the ribs 15. be able to.

  In particular, since the elastic deformation amount of the protrusion 12 is restricted by the rib 15, the deformation of the protrusion 12 is not deformed to the plastic region. For this reason, the protrusion 12 is quickly restored.

  FIG. 5 shows a modified example related to the configuration of the rib 15 when the cross-sectional shape of the rib 15 is seen by the cross section taken along the line VV in FIG. As a cross-sectional shape of the rib 15 shown in FIG. 5A, a configuration example in which an L crank-shaped gap 16 is formed in the rib 15 is shown. By forming the ribs 15 in this way, when the protrusions 12 are elastically deformed, the end faces 15a and 15b facing each other with the gap 16 therebetween can be reliably brought into contact with each other.

  As the cross-sectional shape of the rib 15 shown in FIG. 5B, the rib 15 has a U-shaped cross-sectional shape, and the contact area between the end faces 15a and 15b facing each other with the gap 16 therebetween is widened. be able to. Moreover, since the rib 15 can have two parallel ribs, when the protruding portion 12 is elastically deformed and the end faces 15a and 15b are in contact with each other, the protruding portion 12 is not further elastically deformed. Thus, it can be strongly supported by the two ribs 15.

  The cross-sectional shape of the rib 15 shown in FIG. 5C is not a configuration having two parallel ribs like the cross-sectional shape of the rib 15 shown in FIG. The contact area between the end faces 15a and 15b is wide. By forming the ribs 15 in this way, when the protrusions 12 are elastically deformed, the end surfaces 15a and 15b facing each other with the gap 16 therebetween can be reliably brought into contact with each other.

  As the cross-sectional shape of the rib 15 shown in FIG. 5D, the shape of one end surface 15a is formed in a concave shape that can include the other end surface 15b. By forming the rib 15 in this manner, when the protruding portion 12 is elastically deformed, the end surface 15b can be reliably brought into contact with the end surface 15a, and the end surface 15b is not in contact with the end surface 15a. Can be prevented.

  FIG. 6 shows a modified example of the arrangement configuration of the projecting portions 12 and the ribs 15 when the cross-sectional shape of the cover main body portion 10 is seen by the cross section taken along the line II-II in FIG. In the arrangement configuration of the protrusion 12 and the rib 15 shown in FIG. 6A, the gap 16 is not formed in the rib 15, but is formed between the back surface 18 side of the protrusion 12 and the end surface 17 of the rib 15. An example of the configuration is shown. That is, the gap 16 is formed on the vehicle front side of the protrusion 12.

In the arrangement configuration of the protruding portion 12 and the rib 15 shown in FIG. 6B, the gap 16 is opposite to the arrangement configuration example in which the gap 16 shown in FIG. An arrangement configuration example in which 16 is formed on the vehicle rear side of the protruding portion 12 is shown.
6A and 6B, the end surface 17 of the rib 15 can be brought into contact with the back surface 18 of the protrusion 12 when the protrusion 12 is elastically deformed.

  In the arrangement configuration of the protruding portion 12 and the rib 15 shown in FIG. 6C, a space 22 is formed between the top portion 12 a of the protruding portion 12 and the rib 15. By forming the space 22 between the top portion 12a of the protruding portion 12 and the rib 15, the protruding portion 12 can be easily crushed when an impact force is applied to the bonnet 4.

  In the arrangement configuration of the protruding portion 12 and the rib 15 shown in FIG. 6D, a configuration example in which the cushioning material 13 is provided in the gap 16 formed in the rib 15 is shown. By providing the cushioning material 13 in the gap 16, the cushioning effect by the cushioning material 13 can be provided in addition to the cushioning effect due to the elastic deformation of the protruding portion 12.

  FIG. 6D shows a configuration example in which the cushioning material 13 is provided in the gap 16 formed in the rib 15. As the cushioning material 13, the gap shown in FIGS. 6A to 6C is used. It can also be set at 16. The amount of the cushioning material 13 provided in the gap 16 is to leave a part of the gap 16 as a space instead of providing the cushioning material for the entire gap 16, so that the deformation when the protruding portion 12 is elastically deformed. Make it easier to do.

  FIG. 7 shows a related configuration of the rib 15 and the protruding portion 12 when the rib 15 is configured by integral molding with the cover main body portion 10. FIG. 7A shows an arrangement configuration of the projecting portions 12 and the ribs 15 when the cross-sectional shape of the cover main body portion 10 is seen by a cross section taken along the line II-II in FIG. FIG. 7B shows a perspective view of the cover main body 10 constituting the protrusion 12 from the outside of the protrusion 12 when viewed through.

  In the configuration example shown in FIG. 7, a part of the cover body portion 10 protrudes outward to form the protrusion 12, and the side surface of the protrusion 12 that is formed by protrusion is recessed inward.
