Description

  The present invention relates to a vehicle trunk lid panel having a top surface portion covering a trunk from above and a rear surface portion covering a trunk from behind.

  Conventionally, as a vehicle trunk lid panel having an upper surface portion and a rear surface portion, one having an inner panel and an outer panel is known. For example, in Patent Document 1, an inner panel having an inner upper surface covering the trunk from above and an inner rear surface covering the trunk from behind, and an outer upper surface covering the inner upper surface from above and an outer covering the inner rear from behind A vehicle trunk lid panel is disclosed having an outer panel having a rear surface portion. In such a vehicle trunk lid panel, the bending rigidity in the longitudinal direction of the vehicle, that is, the front end portion of the upper surface portion and the outer end portion in the vehicle width direction as a fulcrum Stiffness is required when an external force is applied in the direction in which the angle with the surface increases. For this reason, in Patent Document 1, an annular bead is formed on the inner panel so as to be continuously and annularly connected along the outer edge of the inner panel. The cross section of the annular bead is formed in a shape that is convex toward the trunk room. That is, the annular bead has a bead bottom and a bead vertical wall rising from the bead bottom. This annular bead enhances the bending rigidity of the inner panel in the front-rear direction, and hence the rigidity of the vehicle trunk lid panel also increases.

  In recent years, there is an increasing need for weight reduction in vehicle trunk lid panels as described in Patent Document 1, but it is difficult to achieve weight reduction while securing bending rigidity with this vehicle trunk lid panel . For example, it may be considered to form the inner panel with a metal having a small specific gravity for weight reduction, but depending on the material constituting the inner panel, the boundary between the upper inner surface and the inner rear surface (bending In part (1), it is necessary to reduce the height of the bead (the dimension from the bead bottom to the upper end of the bead vertical wall). It is possible to compensate for the decrease in flexural rigidity of the inner panel due to this by increasing the thickness of the entire inner panel, but doing so would increase the weight of the vehicle trunk lid panel and also reduce the cost. Also increases.

  An object of the present invention is to provide a vehicle trunk lid panel that can be reduced in weight while securing bending rigidity.

  As a result of earnestly examining in order to solve the above-mentioned subject, the present inventors are based on the structure (section coefficient) of a bent part which is a boundary part of an inner upper surface part and an inner back surface part greatly contributing to bending rigidity. Not only the section coefficient of the bent portion is increased only by the shape of the bead of the inner panel, but also by reinforcing the bent portion with a member different from the inner panel, the section coefficient of the bent portion is increased. It was conceived that it would be possible to reduce the thickness of the inner panel, that is, to reduce the weight of the vehicle trunk lid panel while securing the bending rigidity required for the trunk lid panel.

  The present invention has been made based on the above-mentioned viewpoints. Specifically, the present invention is a trunk lid panel for a vehicle that covers a trunk room provided at the rear of a cabin of a vehicle, the inner upper surface portion covering the trunk room from above and the rear of the inner upper surface portion in the front-rear direction of the vehicle An inner panel connected to an end portion and having an inner rear surface portion covering the trunk from behind, an outer upper surface portion covering the inner upper surface portion from above, and an outer panel having an outer rear surface portion covering the inner rear surface portion from the rear; A reinforcing member for reinforcing the inner panel, the inner panel having an outer peripheral bead provided at an outer edge portion of the inner panel and having a shape continuously connecting in a ring shape along the outer edge portion; The outer peripheral bead has a bead bottom and a bead vertical wall rising from the bead bottom, and the reinforcing member is It has a bending part reinforcement part provided in a bending part which is a connection part of the inner upper surface part and the inner back surface part among outer bead, and the above-mentioned bending part reinforcement part is a shape which increases the section coefficient of the above-mentioned bending part Providing a trunk lid panel for a vehicle.

  In the trunk lid panel for a vehicle according to the present invention, a bending portion reinforcing portion having a shape for increasing the cross section coefficient of the bending portion is provided in the bending portion of the outer peripheral bead which is a portion greatly contributing to the bending rigidity in the longitudinal direction of the vehicle. Accordingly, it is possible to reduce the thickness of the inner panel, that is, to reduce the weight of the vehicle trunk lid panel while securing the bending rigidity required for the vehicle trunk lid panel.

  In this case, the bent portion reinforcing portion may have a rising portion rising from the outer peripheral bead, and a facing portion connected to the upper end portion of the rising portion and facing the outer panel.

  In this case, the rising portions have a pair of rising pieces that respectively rise from the outer circumferential bead and face each other in the vehicle width direction, and the facing portions are connected to the upper ends of the rising pieces. Is preferred.

  In this aspect, in the bent portion, the closed cross section is formed by the outer peripheral bead, the pair of rising pieces and the facing portion, so the bending rigidity in the front-rear direction of the vehicle trunk lid panel is further enhanced. Further, since the outer circumferential bead is suppressed from being compressed and deformed in the vehicle width direction by the structure of the closed cross section, bending rigidity in the vehicle width direction of the vehicle trunk lid panel is also enhanced.

  Moreover, it is preferable to further provide an adhesive member which adheres the said opposing part and the back surface of the said outer panel.

  By so doing, bending stiffness is further enhanced.

  Further, the bent portion reinforcing portion has a shape extending along the outer peripheral bead so as to straddle the bent portion, and the height dimension of the rising portion in the bent portion is other than the bent portion in the outer peripheral bead Preferably, the height dimension is larger than the height dimension of the rising portion at the portion of.

  By so doing, the cross section coefficient at the bent portion effectively increases with respect to the bending in the front-rear direction of the vehicle trunk lid panel, so the bending rigidity in the front-rear direction of the vehicle trunk lid panel is further enhanced.

  Further, in the vehicle trunk lid panel, the bent portion reinforcing portion may have a shape which is convex toward the trunk room.

  In this aspect, the cross section coefficient of the bent portion is effectively increased by the bent portion reinforcing portion having a shape which is convex toward the trunk room.

  In this case, preferably, the bent portion reinforcing portion has a reinforcing bottom portion, and a pair of reinforcing vertical walls which rise from the reinforcing bottom portion and face each other in the vehicle width direction.

  In this way, the cross section coefficient of the bending portion is more effectively increased.

  Moreover, the said bending part reinforcement part may further have the to-be-joined part which is connected to the upper end part of the said pair of reinforcement vertical wall, and is joined to the back surface of the said outer periphery bead.

  In this aspect, the cross-sectional coefficient of the bent portion is effectively increased by the bonded portion being bonded to the back surface of the outer peripheral bead.

  Alternatively, the bead bottom portion has an insertion hole for allowing insertion of the reinforcing bottom portion and the pair of reinforcing vertical walls, and the bent portion reinforcing portion is connected to the pair of reinforcing vertical walls and the pair of reinforcing portions You may further have a to-be-joined part joined to the upper surface of the said outer periphery bead in the state in which the vertical wall was located in the said penetration hole.

  In this aspect, the inner surface of the bead is reduced in weight by the bead bottom portion having the insertion hole, and the outer peripheral bead is formed after the pair of reinforcing vertical walls and the reinforcement bottom portion are inserted into the insertion hole from above the insertion hole. Since it is possible to join to the upper surface of the above, the attachment of the bending portion reinforcement portion to the inner panel is facilitated.

  Preferably, the reinforcing member further includes a hinge reinforcing portion connected to the bending portion reinforcing portion to fix a hinge connecting the inner panel and the outer panel to the vehicle main body.

  In this way, manufacture of the bent portion reinforcing portion and the hinge reinforcing portion becomes easier as compared with the case where a member for fixing the hinge is separately prepared.

  In this case, the thickness of the hinge reinforcing portion is preferably larger than the thickness of the bending portion reinforcing portion.

  In this way, the strength of the hinge reinforcing portion can be effectively secured while avoiding an increase in the weight of the entire reinforcing member.

  As described above, according to the present invention, it is possible to provide a vehicle trunk lid panel that can be reduced in weight while securing bending rigidity.
