Description

  The present invention relates to a pedestrian protection device for a vehicle including a hollow plate-like leg cleaning member.

  Conventionally, various protective devices for absorbing impact energy generated at the time of a collision and protecting a vehicle body and an occupant are installed in front, rear, or side of the vehicle. On the other hand, in recent years, a pedestrian protection device for protecting a pedestrian when a pedestrian collides or comes into contact with the front surface of the vehicle is also installed in front of the vehicle.

  As one of such pedestrian protection devices, a so-called leg wiper member is known which is installed inside the front bumper or at the lower part of the front bumper independently of the front bumper. The leg washer removes the pedestrian's leg by giving the pedestrian's leg a reaction force against the impact load that is input when the pedestrian collides with the front of the vehicle. Toppling. Thereby, the occurrence of injury to the pedestrian's leg, such as a fracture, is prevented as much as possible, and the pedestrian is protected and safe. Therefore, it is required for the leg washer to ensure a sufficient reaction force against the impact load input from the front of the vehicle.

  Therefore, a pedestrian protection device provided with leg-pasting members having various structures has been proposed so far. For example, in Patent Document 1, a resin foam that is installed in a lower region in front of the vehicle and that extends in the vehicle width direction with at least a portion protruding from the front surface of the vehicle, contacts the back surface of the resin foam, There is disclosed a pedestrian protection device including a beam member extending in the direction. Patent Document 2 discloses a pedestrian protection device that is made of a metal pipe or the like and is fixed to a lower region in front of the vehicle along the vehicle width direction. Further, in Patent Document 3, there are two types of reinforcing beads having a U-shaped cross section viewed from the front of the vehicle, each of which is formed in a solid plate shape and protrudes up and down from the rear portion. A synthetic resin pedestrian protection device is disclosed that includes alternating front portions.

  However, since the pedestrian protection device described in Patent Document 1 is composed of a resin foam and a beam member, the number of parts increases, resulting in an increase in part costs. Further, in the devices described in Patent Document 2 and Patent Document 3, a metal pipe is used, or a reinforcing bead having a complicated configuration is formed to increase the rigidity of the front portion of the plate. Inevitably increased. This is not preferable from the viewpoint of reducing the weight of the vehicle, which has been demanded in recent years due to energy problems.

  Accordingly, the present invention provides a vehicle pedestrian protection system that can secure a sufficient reaction force against an impact load input from the front of the vehicle while reducing the cost of components and reducing the weight of the device by reducing the number of components and simplifying the structure. An object is to provide an apparatus.

  In order to achieve the above-described object, the vehicle pedestrian protection device according to the present invention is a plate-like device installed in a lower region in front of the vehicle such that the first direction which is the longitudinal direction is parallel to the vehicle width direction. The leg-paying member is provided with a leg-paying member that is disposed substantially parallel to a plane including at least a vehicle front-rear direction and a vehicle width direction, and the leg-paying member has a predetermined interval. The first plate member and the second plate member, which are formed between the first plate member and the second plate member, the first plate member and the second plate member which are arranged opposite to each other and constitute a hollow plate. A plurality of ribs extending in a second direction orthogonal to the first direction, each rib being an area on at least the vehicle front side of the leg-pasting member. A closed closed-section structure extending in the second direction between the first plate member and the second plate member. So it is more formed along the first direction are continuously coupled to the first plate member and second plate member.

  In such a vehicle pedestrian protection device, a plurality of legs extending in the vehicle front-rear direction are formed on the leg-pasting member with respect to an impact load input in the vehicle front-rear direction from the side surface on the vehicle front side in the event of a collision with a pedestrian With this closed cross-sectional structure, sufficient rigidity is provided. Sufficient rigidity of such a leg member is achieved by a simple structure constituted by two plate members and a plurality of ribs. Therefore, the generation of a sufficient reaction force against the impact load can be realized by an extremely lightweight leg-pasting member without requiring a complicated structure or separate parts, and without increasing the number of parts and parts cost. Become.

  As described above, according to the present invention, for a vehicle that can secure a sufficient reaction force against an impact load input from the front of the vehicle while reducing the cost of the component and reducing the weight of the device by reducing the number of components and simplifying the structure. A pedestrian protection device can be provided.

It is a schematic perspective view which expands and shows another modification of the leg payment member in one Embodiment of this invention partially.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view schematically showing a leg wiping member of a vehicle pedestrian protection apparatus according to an embodiment of the present invention. FIG. 2 is a plan view schematically showing the leg cleaning member shown in FIG. 3A is a cross-sectional view schematically showing the leg-pasting member shown in FIG. 1, and FIG. 3B is a partially enlarged view of FIG.

  The leg-pasting member according to the present embodiment is an elongated plate-like member, and is disposed in parallel to a plane (horizontal plane) including the vehicle front-rear direction and the vehicle width direction with respect to the vehicle, and the longitudinal direction thereof. It is assumed that the vehicle is installed so that the direction is parallel to the vehicle width direction. Therefore, in the following description, each direction in the plate | board surface of a leg wiping member shall be each direction of the corresponding vehicle in the state installed in the vehicle. That is, as shown in each drawing, the longitudinal direction (first direction) of the leg-pasting member is the vehicle width direction W, and the direction orthogonal to the longitudinal direction (second direction) is the vehicle longitudinal direction L. Therefore, the plan view of FIG. 2 shows the leg cleaning member viewed from the vehicle vertical direction, and the cross-sectional view of FIG. 3 shows the cross section of the leg cleaning member viewed from the vehicle front-rear direction.

  As shown in FIG. 1, the leg-pasting member 10 of this embodiment is formed in a flat plate shape, and has an elongated rectangular planar shape as a whole. That is, the leg-wiping member 10 has a rectangular shape in which the dimension in the vehicle width direction (see arrow W in FIG. 1) shorter than the vehicle width is sufficiently longer than the dimension in the vehicle longitudinal direction (see arrow L in FIG. 1). It is formed into a shape. As shown in FIG. 2, the side surface 20 on the front side of the vehicle (impact input surface) 20 to which an impact load is input when colliding with a pedestrian is located on the front side of the leg wiper member 10 when viewed from the vehicle vertical direction. It has a convex curved shape toward the front of the vehicle so as to correspond to the inner surface shape of a front bumper (bumper cover) described later. The impact input surface 20 causes the impact load to be input in parallel to the leg wiper member 10 when the leg wiper member 10 is installed in the vehicle so as to be parallel to a horizontal plane including the input direction of the impact load. It is preferable to be configured as described above. That is, in the present embodiment, the impact input surface 20 is formed to be perpendicular to the plate surface of the leg member 10 in order to ensure sufficient rigidity against the impact load. The leg removing member 10 is made of, for example, a thermoplastic resin material such as polypropylene or ABS resin.

  As shown in FIG. 3, the leg disposing member 10 is disposed to face each other at a predetermined interval, and includes an upper plate (first plate member) 10 a and a lower plate (second plate member) 10 b that constitute a hollow plate. It has. Between the upper plate 10a and the lower plate 10b, that is, inside the hollow plate, a plurality of ribs 10c that connect the upper plate 10a and the lower plate 10b and extend in the vehicle longitudinal direction L are provided. Each rib 10c is continuously coupled to the upper plate 10a and the lower plate 10b, whereby each of the leg-pasting members 10 extends in the vehicle longitudinal direction L as shown in FIG. A plurality of hollow closed cross-sectional structures 10d are formed along the vehicle width direction W. In other words, the leg washer member 10 of the present embodiment has a plurality of closed cross-sectional structures that extend in the direction of the impact load (vehicle longitudinal direction L) that is input at the time of a collision with a pedestrian and are juxtaposed in the vehicle width direction W. 10d.

  In the leg wiping member 10 of the present embodiment, a plurality of closed cross-sectional structures 10d continuous in the vehicle width direction W are formed, so that the impact load input from the impact input surface 20 of the leg wiping member 10 is Propagation in the vehicle width direction W is facilitated. As a result, the leg cleaning member 10 of the present embodiment can obtain sufficient rigidity against an impact load even if the overall weight is light. The closed cross-sectional structure 10d does not require a complicated structure such as a reinforcing bead described in Patent Document 3 or additional separate parts, and is formed on the upper plate 10a, the lower plate 10b, and between them. It is formed only by a plurality of ribs 10c. Therefore, the leg washer 10 of the present embodiment has a simple structure of the closed cross-sectional structure 10d, while ensuring a sufficient reaction force against the impact load, the weight of the device can be reduced by simplifying the structure, and the number of parts can be reduced. It is possible to realize a reduction in component costs due to the reduction.

  In addition, in the present embodiment, as described above, each rib 10c is continuously coupled to all regions of the upper plate 10a and the lower plate 10b. The payer member 10 is formed from the vehicle front side surface to the rear side surface. Thereby, in the leg member 10 of this embodiment, integral molding by extrusion molding is attained. This is advantageous in terms of manufacturing cost as compared with the case of injection molding used for molding a leg member having a solid plate-like portion as described in Patent Document 3, for example.

  In addition, when there is a difference in rigidity with respect to the impact load between the upper part and the lower part when viewed from the front of the vehicle, the leg washer is either upper or lower when the impact load is input. It is lifted or pushed down only on one side, and a delay is induced in the rising of the impact load in the load characteristics. As a result, there is a possibility that a sufficient reaction force against the impact load cannot be instantly exhibited. Therefore, as shown in FIG. 3B, the leg washer member 10 of the present embodiment has ribs 10c with respect to an intermediate line C between the upper plate 10a and the lower plate 10b when viewed from the vehicle longitudinal direction L. It is preferable that they are formed so as to be symmetrical. Therefore, in this embodiment, each closed cross-section 10d viewed from the vehicle longitudinal direction L is formed in a rectangular shape. Thereby, it is possible to effectively avoid the above-described problems that may be caused by the difference in rigidity.

  Next, with reference to FIG. 4 and FIG. 5, the structure and pedestrian protection operation | movement of a pedestrian protection apparatus provided with the leg payment member of this embodiment are demonstrated.

  FIG. 4 is a cross-sectional view schematically showing a state in which the leg-paying member of this embodiment is assembled to a vehicle to constitute a pedestrian protection device, and FIG. 5 is a front view of the vehicle in the pedestrian protection device shown in FIG. It is sectional drawing which shows roughly the state which the pedestrian collided from. 4 and 5 both show a cross section viewed from the vehicle width direction.

  In the pedestrian protection device 1 according to the present embodiment, the leg-pasting member 10 is disposed on the front surface of the vehicle so as to be parallel to the vehicle front-rear direction L, that is, the horizontal plane including the input direction of the impact load, as shown in FIG. It is arranged inside the installed front bumper 30. The front bumper 30 includes a bumper cover 33 that is fixed to the front grill 40 by bolts or the like, for example. The bumper cover 33 that constitutes the front portion of the vehicle includes an upper protruding portion 31 and a lower protruding portion 32, each of which has a cross section perpendicular to the vehicle width direction curved in a convex shape toward the front of the vehicle. Is housed inside the lower protrusion 32. On the other hand, inside the upper protrusion 31 of the bumper cover 33, a known shock absorbing structure 34 that is fixed to the bumper reinforcement 35, which is a rigid member, and has a rigidity smaller than that of the leg wiper member 10 is installed. .

  A plurality of insertion holes 16 are provided at a rear end portion of the leg wiping member 10 at a predetermined interval in the vehicle width direction W (four in this embodiment, see FIG. 2). An attachment member 15 for fixing the leg disposing member 10 to a body member, here, a radiator support 61 that supports the radiator 60 is attached to the insertion hole 16 by a fixing bolt 17. By bolting the attachment member 15 to the radiator support 61 with the fixing bolt 18, the leg cleaning member 10 is fixed to the body member (radiator support 61) at the rear end.

  As shown in FIG. 5, when the pedestrian leg 70 comes into contact with or collides with the bumper cover 33 of the front bumper 30, the upper protrusion 31 and the lower protrusion 32 of the bumper cover 33 form the pedestrian leg 70. The knee portion 71 and the shin portion 72 are in contact with each other. At this time, since the rigidity of the shock absorbing structure 34 is smaller than the rigidity of the leg cleaning member 10, the shock absorbing structure 34 is easily deformed with a larger deformation amount than the leg cleaning member 10. Therefore, after the bumper cover 33 collides with the bumper cover 33, the bumper cover 33 is deformed into a shape in which the lower protrusion 32 protrudes further forward. Thereby, a reaction force against the impact load generated in the leg wiping member 10 acts on the shin portion 72 of the pedestrian's leg portion 70 via the lower protruding portion 32 of the bumper cover 33. As a result, the pedestrian 72 falls on the bonnet 80 side of the automobile, with the shin portion 72 of the leg portion 70 being removed (squeezed up) by the leg-wiping member 10. In this way, by reducing the bending of the pedestrian's knee portion 71 in an unreasonable direction, it is possible to prevent the occurrence of injury such as a fracture to the knee portion 71 as much as possible. It is possible to effectively realize the protection and safety of the person.

  As described above, the leg member of this embodiment is installed in the lower region in front of the vehicle so as to be substantially parallel to the horizontal direction including the vehicle front-rear direction, that is, the input direction of the impact load. That is, in this embodiment, the closed cross-sectional structure comprised by the upper board and the lower board, and the rib formed between these is provided so that it may extend in parallel with the input direction of an impact load. Thereby, in this embodiment, sufficient rigidity with respect to the input of an impact load is ensured efficiently even if it is lightweight in a leg-pasting member. In addition, a plurality of closed cross-sectional structures are continuously formed in the vehicle width direction, and the thickness of each closed cross-sectional structure is changed as necessary according to the rigidity of the peripheral parts. It is possible to change the rigidity of the leg-wiping member. Therefore, even if the leg part of the pedestrian contacts or collides with any part of the leg wiper member, the leg part of the pedestrian can be quickly and reliably paid, and the pedestrian can be protected and safe. . Furthermore, each closed cross section viewed from the front-rear direction of the vehicle is vertically symmetrical, that is, rectangular, so that when the impact load is input, the leg-pasting member is lifted or pushed down only to either the upper or lower side. It is also advantageous to avoid the generation of such acting force.

  In addition, it is sufficient if the leg washer has such a rigidity that the leg of the pedestrian can be removed at the time of collision with the pedestrian. For this reason, the closed cross-sectional structure does not necessarily have to be formed over the entire range of the leg-pasting member in the vehicle front-rear direction, and it is sufficient if it is formed at least in a region in front of the vehicle including the impact input surface. In that case, the area | region of the vehicle rear side of a leg wiping member may be formed in the solid plate shape, if weight reduction can be achieved as the whole leg wiping member.

  Next, with reference to FIG. 6 to FIG. 10, some modified examples of the leg cleaning member of this embodiment will be described.

  FIG. 6 is a schematic cross-sectional view corresponding to FIG. 3 (b), showing a modified example in which the shape of the closed cross-sectional structure is changed, and FIG. 7 is a cross-sectional shape of the leg cleaning member viewed from the vehicle width direction. It is a schematic sectional drawing which shows a modification. 8 (a) and 8 (b) are schematic plan views showing a modification in which a concave groove is added to the leg-wiping member, and FIG. 8 (c) is a plan view of FIG. 8 (a) and FIG. It is a schematic sectional drawing in alignment with the AA 'line of FIG.8 (b). FIG. 9 is a schematic perspective view showing a partially enlarged example of a modification in which an opening is provided in the upper plate of the leg cleaning member.

  In the embodiment shown in FIG. 3B, each rib 10c is formed so that each closed cross-section 10d is rectangular, but the present invention is not limited to this. What is necessary is just to be formed so that it may become symmetrical with respect to the intermediate line of a board and a lower board. That is, as shown in FIG. 6A, each rib 10c ′ may be formed such that each closed section 10d ′ is O-shaped, or each rib 10c ″ is formed as shown in FIG. ), It may be formed in an X shape.

  Further, as described above, the leg washer is sufficient if it has sufficient rigidity to be able to pay the pedestrian's leg at the time of collision with the pedestrian, and for that purpose, it includes an impact input surface. It suffices that at least the vehicle front side region is arranged in parallel to the horizontal plane. Therefore, the shape of the leg cleaning member can be appropriately changed in accordance with the shape inside the vehicle, that is, the vehicle layout of the peripheral parts on which the leg cleaning member is disposed. For example, as shown in FIG. 7, in the cross section viewed from the vehicle width direction W, the leg-pasting member 10 ′ is arranged such that the heights of the leg-pasting member 10 ′ are changed between the vehicle front part 11 and the vehicle rear part 12. It is also possible to make a step in the vertical direction of the vehicle.

  In addition, in order to obtain a stable load characteristic in the vehicle longitudinal direction of the leg washer, the upper plate and the lower plate are more rigid than the other parts of the upper plate and the lower plate, which are the starting points of bending when an impact load is input. Weak low-rigidity parts can also be juxtaposed in the vehicle longitudinal direction. As such a low-rigidity part, for example, as shown in FIG. 8, a concave groove 83 extending in the vehicle width direction W can be provided in each of the upper plate 10a and the lower plate 10b. The concave grooves 83 are disposed so as to be substantially parallel to the impact input surface 20 and are disposed so as not to overlap each other when viewed from the vehicle vertical direction. Instead of the concave groove 83, a slit or a plurality of holes juxtaposed at a predetermined interval may be provided. In addition to this, a plurality of notches can be provided at a predetermined interval on the impact input surface 20 of the leg wiping member 10, whereby stable load characteristics of the leg wiping member 10 in the vehicle width direction W can be provided. You can also get Furthermore, when the required rigidity of the leg-pasting member differs in the vehicle width direction, in addition to changing the plate thickness of each closed cross-sectional structure in the vehicle width direction described above, a plurality of closed cross-sectional structures By injecting a separate material such as a hard resin into the predetermined hollow space, a high-rigidity region and a low-rigidity region can be set along the vehicle width direction.

  Further, as shown in FIG. 9, a large number of apertures 81 may be provided on the upper plate 10a side of the leg disposing member 10, that is, the side facing the engine room. Thereby, the sound emitted from an engine room is penetrated into the hollow space inside the leg wiping member 10 and attenuated, so that a sound absorbing action can be imparted to the leg wiping member 10.

  Further, in the embodiment shown in FIG. 1, the front end surface and the rear end surface of the leg wiping member 10, that is, both end portions of the closed cross-sectional structure are open, but for example, either the upper plate or the lower plate is used for the vehicle. It can also be made into the closed state as needed by extending in the front-back direction and bending the part into a flap shape. Thereby, invasion of dust, water or the like into the hollow space inside the leg wiping member can be prevented.

  As mentioned above, although the specific structure of the pedestrian protection apparatus for vehicles of this invention was explained in full detail, this is only a mere illustration and does not limit this invention at all. Based on the knowledge of those skilled in the art, it should be understood that other embodiments with various changes, modifications and improvements are possible without departing from the spirit of the invention.

  For example, as a material of the leg member 10, a metal material that is relatively lightweight and excellent in moldability, such as aluminum or an aluminum alloy, may be used instead of the thermoplastic resin material. Further, regarding the method of installing the leg wiper member 10 in the lower region in front of the vehicle, the fixing position of the vehicle to which the leg wiper member 10 is fixed and the fixing method of the rear end portion of the leg wiper member 10 are appropriately changed. Is possible. Further, in the above-described embodiment, the reaction force against the impact load generated by the leg cleaning member 10 acts on the shin 72 of the leg part 70 of the pedestrian. You may come to act on other site | parts of a pedestrian's leg by changing an installation position.

  In addition to the pedestrian protection device installed inside the front bumper on the front side of the vehicle, the present invention is installed in various forms on the front side of the vehicle, such as a pedestrian protection device installed separately from the front bumper. Needless to say, the present invention is applicable to any of the pedestrian protection devices used.

(Example)
The leg-paying member (example) of this embodiment shown in FIGS. 1 to 3 and the leg-paying member (comparative example) having the same configuration as the leg-paying device described in Patent Document 3 are used. The effect was confirmed.

  First, in Examples and Comparative Examples, polypropylene was used as the material for the leg-pasting member, and leg-pasting members having substantially the same outer dimensions were prepared by extrusion molding (Example) and injection molding (Comparative Example), respectively. The leg-pasting member thus prepared is installed inside the bumper cover of the front bumper fixed to the front surface of the actual vehicle (automobile) in the configuration shown in FIG. Got the vehicle. Then, using these two types of test vehicles, a collision test was performed assuming a pedestrian collision with the front bumper of the automobile, and the impact load input to each leg-paying member at the time of the collision was examined by a known method. . The collision test for each test vehicle was performed by causing a dummy having a predetermined weight to collide with the front surface of the front bumper at a predetermined speed.

  In the embodiment, without changing the external dimensions, the weights of the members were changed using parameters such as the thicknesses of the upper plate, the lower plate, and the ribs to produce several leg-pasting members, and the respective leg-pasting members were installed. A collision test was conducted on a test vehicle. According to this, in the example, a peak load equivalent to that obtained in the comparative example could be obtained with the leg-pasting member having a weight approximately half that of the leg-pasting member of the comparative example. Thereby, it was confirmed in the Example that significant weight reduction was achieved while ensuring an equivalent reaction force against the impact load as compared with the Comparative Example.
