  BACKGROUND ART Conventionally, as a support structure for a vehicle board member, a structure described in Patent Literature 1 is known. In the support structure for a vehicle board member described in Patent Literature 1, legs 40a projecting downward so as to contact the upper surface of the floor panel 30 and extending in the left-right direction are respectively provided at front and rear end portions on the lower surface of the floorboard 40. It is disclosed that it is formed.

JP 2011-093508 A

  However, in the configuration disclosed in Patent Literature 1, since the upper surface of the floor panel 30 and the leg portion 40a are in surface contact with each other, the vibration generated by the movement of the vehicle or the like is transmitted to the contact surface to generate sound. In such a case, the occupant may feel uncomfortable riding comfort due to the vibration sound echoing in the vehicle interior. Further, even if a nonwoven fabric or the like is provided on the contact surface in order to reduce such a noise, it is troublesome and costly.

  The present invention has been completed based on the above circumstances, and is a support structure for a vehicle board member that can suppress generation of vibration noise from a support member provided on the board member and a grounding surface. One of the purposes is to provide Another object of the present invention is to reduce labor and cost in manufacturing a support structure for the vehicle board member.

  The present invention is a support structure for a vehicle board member that supports a plate-like board member installed on a vehicle, and a support member for supporting the board member from a ground surface is provided on a lower surface of the board member. The support member is provided so as to protrude downward from the lower surface, and the support member includes a main body extending downward from the lower surface of the board member, and a tip end extending further downward from the main body and in contact with the ground plane, The distal end is formed in a hollow shape, and the distal end is formed in a U-shape curved toward the ground contact surface side, and the wall portion is penetrated at both ends in the extending direction of the U-shape. .

  According to such a support structure for a vehicle board member, since the protrusion has the front end portion curved into a U-shaped streak, the front end of the support member and the ground contact surface are in line contact. Therefore, the contact area is smaller than in the case where the contact is made on the surface, so that the vibration noise generated by the movement of the vehicle or the like on the contact surface can be reduced. In addition, since the distal end portion has the wall portions penetrating at both ends in the extending direction of the U-shaped strip, the distal end portion can be bent when a downward pressure is applied to the board member. Therefore, even if vibration occurs between the support member and the grounding surface, the distal end portion bends and absorbs vibration, so that vibration noise can be reduced. For these reasons, it is possible to suppress the occupant from feeling uncomfortable riding due to the vibration sound reverberating in the vehicle interior. Further, there is no need to install a nonwoven fabric or the like on the contact surface in order to reduce the vibration noise, so that labor and cost can be reduced.

  The said structure WHEREIN: The said main-body part can be set as the partially notched cylindrical shape which notched one side surface. According to such a support structure for a vehicle board member, since the main body has a configuration in which one side surface is cut, the rigidity is higher than that of the front end portion of the penetrating configuration. Therefore, when a downward pressure is applied to the board member, the force is concentrated on the curved surface portion and the board member is easily bent, and the vibration sound can be further reduced.

  In the above configuration, a partition wall serving as a wall separating the hollow main body portion and the distal end portion may be provided. According to such a support structure for a board member for a vehicle, the partition wall connects the main body portion and the distal end portion, so that the rigidity of the main body portion in a portion that is not cut is further increased. On the other hand, the rigidity of the cut-out portion becomes relatively weaker. Therefore, the tip portion is more easily bent, and the vibration noise can be further reduced.

  In the above configuration, the board member may constitute a package tray of the vehicle, and the pair of support members may be disposed on both sides in the vehicle width direction. According to such a support structure for a board member for a vehicle, the package tray is supported by a pair of support members disposed on both sides in the vehicle width direction. Even so, the package tray can be stabilized. Further, it is not necessary to install a nonwoven fabric or the like between the support member and the grounding surface in order to reduce the vibration noise, so that labor and cost can be reduced.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the support structure of the board member for vehicles which can suppress generation | occurrence | production of a vibration sound from the support member joined to the board member and the grounding surface. Further, in manufacturing the support structure for the vehicle board member, it is possible to reduce labor and cost.

It is a hollow space surrounded by the parts 12, 12, the curved surface part 21, and the partition wall part 30.

  Subsequently, a mode of the support member 5 when the package tray 1 is installed on the upper surface of the deck side trim 2 will be described. As shown in FIG. 1, the package tray 1 is disposed above a deck side trim 2 forming left and right side walls in a luggage compartment 8 provided at the rear of the vehicle. At this time, on the lower surface 3 of the package tray 1, the pair of support members 5 arranged on both sides in the vehicle width direction of the vehicle come into contact with the ground contact surface 4 on the upper side of the deck side trim 2, so that the package tray 1 becomes the deck side trim 2. The structure is supported above.

  FIGS. 3 to 5 show the grounding state of the support member 5 and the grounding surface 4 in the support structure in an enlarged manner. Since the distal end portion 20 of the support member 5 forms a U-shaped ridge whose distal end bulges toward the ground surface 4 side, that is, a curved surface, the lowermost part of the curved surface and the ground surface 4 extend in the extending direction of the U-shaped line. Tangent line 40 on a line extending in the vehicle width direction (represented by a two-dot chain line). In FIG. 5 in which the support member 5 and the ground plane 4 are viewed from the right side, the tangent line 40 is indicated by a dot.

  When downward pressure is applied to the package tray 1 due to, for example, vibration of the vehicle, the side wall portion 12 of the tip portion 20 expands in the front-rear direction with the tangent line 40 as a fulcrum, and the curved surface portion 21 approaches a flat surface. Become. That is, when viewed from the right, the penetrating portion 26 is crushed from a semi-cylindrical shape to approach a rectangle. On the other hand, the main body 10 has a wall 11 connected to the side wall 12, the partition 30 is connected to the wall 11 and the side wall 12, and the front side wall 12 is connected to the rib 7. Elastic deformation like the part 20 does not occur, and it is hard to bend. As described above, when the vehicle is vibrating, it is assumed that the distal end portion 20 that is in contact with the grounding surface 4 elastically deforms and bends in accordance with the vibration, or returns to the state before being bent by elastically recovering. Will repeat.

  Subsequently, effects of the present embodiment will be described. In the present embodiment, a support member 5 for supporting the board member 1 from the ground plane 4 is provided on the lower surface 3 of the board member 1 so as to protrude downward from the lower surface 3. It has a main body 10 extending downward from the lower surface 3, and a tip 20 extending further downward from the main body 10 and in contact with the ground plane 4. It is configured to be a U-shaped bend to the side, and the wall portion 11 penetrates at both ends in the extending direction of the U-shaped. According to such a configuration, since the protruding portion includes the front end portion 20 whose front end is curved in a U-shape, the front end of the support member 5 and the ground contact surface 4 are in line contact with each other. Therefore, the contact area is smaller than in the case where the contact is made on the surface, so that the vibration noise generated by the movement of the vehicle or the like on the contact surface can be reduced. Further, since the wall portion 11 penetrates the distal end portion 20 at both ends in the extending direction of the U-shaped strip, the distal end portion 20 can bend when a downward pressure is applied to the board member 1. Therefore, even if vibration occurs between the support member 5 and the ground plane 4, the distal end portion 20 bends and absorbs vibration, so that vibration noise can be reduced. For these reasons, it is possible to suppress the occupant from feeling uncomfortable riding due to the vibration sound reverberating in the vehicle interior. Further, there is no need to install a nonwoven fabric or the like on the contact surface in order to reduce the vibration noise, so that labor and cost can be reduced.

  In the present embodiment, the main body 10 is formed in a partially cut-out cylindrical shape with one side cut out. According to such a configuration, since the main body 10 has a configuration in which one side surface is cut out, the rigidity is higher than that of the distal end portion 20 having the penetrating configuration. Therefore, when a downward pressure is applied to the board member 1, the force concentrates on the curved surface portion, and the board member 1 is easily bent, and the vibration noise can be further reduced.

  Further, in the present embodiment, a configuration is provided in which a partition wall portion 30 serving as a wall separating the hollow main body portion 10 and the distal end portion 20 is provided. According to such a configuration, since the partition wall portion 30 connects the main body portion 10 and the distal end portion 20, the rigidity of the main body portion 10 in a portion that is not cut is further increased. On the other hand, the rigidity of the cut-out portion becomes relatively weaker. Therefore, the distal end portion 20 is more easily bent, and the vibration noise can be further reduced.

  In the present embodiment, the package tray 1 of the vehicle is configured, and a pair of support members 5 are arranged on both sides in the vehicle width direction. According to such a configuration, since the package tray 1 is supported by the pair of support members 5 arranged on both sides in the vehicle width direction, even if the vibration generated by the movement of the vehicle and the like is different on both sides in the vehicle width direction, The package tray 1 can be stabilized. Further, in order to reduce the vibration noise, it is not necessary to install a nonwoven fabric or the like between the support member 5 and the ground plane 4, so that labor and cost can be reduced.
