  By the way, a vehicle body platform may be shared between vehicles having different appearance designs. In such a case, it is preferable to share the radiator support as a part of the platform. However, since the arrangement height of the hood varies depending on the appearance design of the vehicle, the distance from the hood to the radiator support upper varies depending on the vehicle type. For this reason, when providing a hood stopper structure in the upper part of a radiator support upper, it is necessary to change the height dimension of the above support members according to the arrangement | positioning height of a hood.

  Here, when the arrangement height of the hood is high, it is necessary to increase the height of the support member. Even in such a case, the support member against the impact load when the hood is closed (in order to support the hood stopper). It is necessary to satisfy both the securing of the rigidity of the structure and the shock absorption at the time of collision.

  In consideration of the above facts, an object of the present invention is to provide a hood stopper structure for an automobile capable of ensuring both rigidity of the structure for supporting the hood stopper and shock absorption at the time of collision.

  According to a first aspect of the present invention, there is provided a hood stopper structure for an automobile. A pair of left and right support members each having a lower end side coupled to a radiator support upper of a vehicle and projecting upward from the radiator support upper to the vehicle, and the radiator support A connecting member provided on the upper vehicle side of the upper and coupled to the upper ends of the pair of support members, and an attachment member provided on the vehicle upper side of the support member and coupled to the connecting member; The radiator support upper is mounted in the vehicle front-rear direction offset from the center position in the vehicle front-rear direction at the portion of the radiator support upper facing the support member, and is directed downward when the vehicle hood is closed. And a hood stopper to which the load of 1 is input.

  In the automobile hood stopper structure according to claim 1, the hood stopper is supported by the radiator support upper via the mounting member, the coupling member to which the mounting member is coupled, and the support member to which the coupling member is coupled. ing. Further, the hood stopper is disposed offset in the vehicle front-rear direction with respect to the center position in the vehicle front-rear direction at the portion facing the support member of the radiator support upper.

  For this reason, for example, when a collision object collides with the hood and a vehicle downward load is input to the hood stopper, a rotational moment is applied to the radiator support upper via the mounting member, the coupling member, and the support member. . As a result, when the radiator support upper is torsionally deformed in the elastic region, the support member, the connecting member, the attachment member, and the hood stopper rotate around the torsion center of the radiator support upper, and the hood stopper is displaced downward in the vehicle. Thereby, since the displacement of the hood to the vehicle lower side is allowed, the impact received by the collision object can be absorbed.

  Further, since the radiator support upper is torsionally deformed in the elastic region due to the rotational moment as described above, displacement of the hood and the hood stopper to the lower side of the vehicle is allowed, so a configuration for supporting the hood stopper (support member, There is no need to deform the connecting member and the attachment part). Therefore, the rigidity of these members can be ensured.

  In addition, when the height dimension of the configuration for supporting the hood stopper is high, the distance from the radiator support upper to the hood stopper is increased, and the rotational moment applied to the radiator support upper is increased. Therefore, it is possible to increase the amount of twist of the radiator support upper with respect to the rotational moment (that is, the amount of displacement of the hood stopper) while ensuring the rigidity of the radiator support upper. Therefore, the rigidity of the radiator support to which a circulator such as a radiator and a condenser is attached can be sufficiently secured, which is preferable.

As a result, the distance (moment arm) between the load input portion to the support member and the torsion center of the radiator support upper can be increased, so that the load input to the hood stopper can be efficiently passed through the support member. Can be transmitted to the support upper. Therefore, the structure of the support member can be simplified and reduced in weight.

It is arranged on an imaginary straight line that passes through (the twist center of the radiator support upper) and the center position of the upper end surface of the hood stopper (center position of the load input portion of the hood stopper). Thereby, the load input to the hood stopper can be transmitted to the radiator support upper through the support member without waste. Therefore, the structure of the support member can be further simplified and reduced in weight.

Rigidity is set higher than the radiator support upper with respect to the load input to the hood stopper.

  In the automobile hood stopper structure according to claim 5, the mounting member and the support member are set to have higher rigidity (difficulty of deformation) than the radiator support upper with respect to the vehicle downward load inputted from the hood to the hood stopper. ing. For this reason, unnecessary deformation of the mounting member and the support member with respect to the load can be suppressed, and the amount of displacement of the hood stopper can be determined by the amount of twist deformation (twist angle) of the radiator support upper. In other words, this hood stopper structure utilizes the fact that the amount of displacement of the hood stopper around the radiator support upper is larger than the amount of displacement of the hood stopper due to the rotational moment about the support member. Thus, the amount of displacement of the hood stopper (that is, the amount of shock absorption) can be increased.

Yes. The hood stopper 42 is formed in a cylindrical shape by an elastic material such as a rubber material or a resin material, and is attached to the rear extension 40B (attachment member 40) by fitting a lower end portion of the stopper attachment hole 40D. It has been.

  The hood stopper 42 protrudes from the rear extension 40 </ b> B to the vehicle upper side, and the upper end surface faces the lower surface of the front end portion of the hood inner panel 20. The front end portion of the hood inner panel 20 is provided with a stopper abutting portion 20 </ b> A that bulges toward the vehicle lower side at a portion facing the upper end surface of the hood stopper 42.

  Here, in the first embodiment, as shown in FIG. 3, the hood stopper 42 has a center position S1 in the vehicle front-rear direction (hereinafter referred to as a torsion center S1) at a portion facing the support member 36 of the radiator support upper 24. ) With respect to the vehicle rear side. Specifically, the hood stopper 42 has a center position S2 of an upper end surface (a surface that contacts the stopper contact portion 20A) separated from the twist center S1 of the radiator support upper 24 by α1 toward the vehicle rear side, and the vehicle upper side. It is arranged in a state separated by β1.

  In the first embodiment, the connecting portion J (spot welded portion) between the connecting member 38 and the support member 36 is located on the vehicle rear side (the same side as the hood stopper 42) with respect to the twist center S1 of the radiator support upper 24. ) Is offset. Specifically, the connecting portion J is disposed in a state of being separated from the torsion center S1 of the radiator support upper 24 by α2 toward the vehicle rear side and by β2 toward the vehicle upper side. Α2 is set smaller than α1, and β2 is set smaller than β1 (α2 <α1, β2 <β1).

  Furthermore, in the first embodiment, the coupling portion J is disposed on a virtual straight line ε (see FIG. 3) passing through the twist center S1 of the radiator support upper 24 and the center position S2 of the upper end surface of the hood stopper 42. Has been.

  In the first embodiment, the support member 36 and the mounting member 40 are more rigid (difficult to deform) than the radiator support upper 24 with respect to the load input to the hood stopper 42 from the stopper contact portion 20A of the hood 16. ) Is set high.

  Next, the operation of the first embodiment will be described.

  In the hood stopper structure 10 configured as described above, the hood stopper 42 is supported by the radiator support upper 24 via the attachment member 40, the connecting member 38, and the support member 36. Further, the hood stopper 42 is disposed offset to the vehicle rear side with respect to the twist center S <b> 1 of the radiator support upper 24.

  For this reason, when a collision object collides with the hood outer panel 18 and a vehicle downward impact load F (see FIG. 4) is input to the hood stopper 42 via the hood inner panel 20, the radiator support upper 24 is attached to the mounting member. A rotational moment is applied through 40, the connecting member 38, and the support member 36. Thus, when the radiator support upper 24 is twisted and deformed in the elastic region, the support member 36, the connecting member 38, the mounting member 40, and the hood stopper 42 rotate around the twist center S1 of the radiator support upper 24, and the hood stopper 42 is It is rotationally displaced downward (see symbol γ in FIG. 4). Thereby, since the displacement to the vehicle lower side of the hood 16 is accept | permitted, the impact which the said collision object receives can be absorbed.

  Further, as described above, the radiator support upper 24 is torsionally deformed in the elastic region due to the rotational moment, so that the hood 16 and the hood stopper 42 are allowed to be displaced downward in the vehicle. There is no need to deform (support member 36, connecting member 38, attachment member 40). Therefore, the rigidity of these members can be ensured.

  Thereby, since it becomes possible to arbitrarily change the height dimension of the support member 36 according to the appearance design of the automobile (the arrangement height of the hood 16), the radiator support 22 can be changed according to the arrangement height of the hood 16. There is no need to change the height dimension (the length dimension of the side frame 28). Therefore, it is possible to share a platform including the radiator support 22 between vehicles having different appearance designs. This makes it easier to build and adjust the vehicle body and improve productivity.

  Moreover, in the hood stopper structure 10, when the height dimension of the configuration for supporting the hood stopper 42 is high, the distance δ from the twist center S 1 of the radiator support upper 24 to the center position S 2 of the upper end of the hood stopper 42. (Refer to FIG. 4) becomes longer and the rotational moment applied to the radiator support upper 24 becomes larger. Therefore, it is possible to increase the amount of twisting of the radiator support upper 24 with respect to the rotational moment (that is, the amount of displacement of the hood stopper 42) while ensuring the rigidity of the radiator support upper 24. Therefore, the rigidity of the radiator support 22 to which a circulator such as a radiator and a condenser is attached can be sufficiently secured, which is preferable.

  In the hood stopper structure 10, when the offset amounts β1 and β2 between the twist center S1 of the radiator support upper 24 and the center position S2 of the upper end surface of the hood stopper 42 are changed by the appearance design of the automobile, the offset is set. The rotational moment applied to the radiator support upper 24 can be adjusted by changing the amounts α1 and α2.

  Further, in this hood stopper structure 10, the vehicle downward impact load F input to the hood stopper 42 is input to the support member 36 via the attachment member 40 and the connection member 38. The joint portion J (the load input portion to the support member 36) is offset from the twist center S1 of the radiator support upper 24 toward the same side (the vehicle rear side) as the hood stopper 42. Thus, the distance (moment arm) between the load input portion (the coupling portion J) of the support member 36 and the torsion center S1 of the radiator support upper 24 can be increased, so that the impact load F input to the hood stopper Can be efficiently transmitted to the radiator support upper 24 via the support member 36. Therefore, simplification and weight reduction of the structure of the support member 36 can be achieved.

In addition, in the hood stopper structure 10, the joint portion J (the load input portion to the support member 36) between the support member 36 and the coupling member 38 has a twist center S 1 of the radiator support upper 24 and an upper end surface of the hood stopper 42. It is arranged on a virtual straight line ε passing through the center position S2 (center position of the input portion of the impact load F). Thereby, the impact load F input to the hood stopper 42 can be transmitted to the radiator support upper 24 through the support member 36 without waste. Therefore, the structure of the support member 36 can be further simplified and reduced in weight.

  Further, in the hood stopper structure 10, the hood stopper 42 is arranged offset to the vehicle rear side with respect to the twist center S <b> 1 of the radiator support upper 24. For this reason, when the radiator support upper 24 is torsionally deformed by the vehicle downward load input to the hood stopper 42, the support member 36, the connecting member 38, the mounting member 40, and the hood stopper 42 are arranged on the vehicle rear lower side ( That is, it is displaced to the engine room 14 side. Therefore, it is suitable for securing a space for displacing these members.

  Further, in the hood stopper structure 10, the attachment member 40 and the support member 36 are set to have higher rigidity than the radiator support upper 24 with respect to the downward impact load F input to the hood stopper 42. Therefore, unnecessary deformation of the mounting member 40 and the support member 36 with respect to the impact load F can be suppressed, and the displacement amount γ of the hood stopper 42 is determined by the twist angle θ of the radiator support upper 24 (see FIG. 4). can do. In other words, the hood stopper structure 10 utilizes the fact that the amount of displacement of the hood stopper 24 centered on the radiator support upper 24 is larger than the amount of displacement of the hood stopper 42 due to the rotational moment about the support member 36. Accordingly, the displacement amount γ (that is, the shock absorption amount) of the hood stopper 42 can be increased.

  In the hood stopper structure 10, the upper end portions of the support members 36 arranged side by side in the vehicle width direction are connected in the vehicle width direction by a connecting member 38. For this reason, even when the height dimension of the support member 36 is high, the rigidity of the support member 36 with respect to the load in the vehicle width direction can be ensured.

  In the first embodiment, the hood stopper 42 is offset from the twist center S1 of the radiator support upper 24 toward the vehicle rear side. However, the present invention is not limited to this, and the hood stopper 42 is not limited thereto. 42 may be configured to be offset from the twisting center S1 of the radiator support upper 24 toward the front side of the vehicle.

  In the first embodiment, the joint J between the support member 36 and the connecting member 38 is offset to the same side as the hood stopper 42 (the vehicle rear side) with respect to the twist center S1 of the radiator support upper 24. However, the present invention is not limited to this, and the coupling portion J may be disposed directly above the twist center. The above points are the same in other embodiments of the present invention described below.
