Japanese Patent Laid-Open No. 10-151948

  A portion where the vehicle door trim is in contact with the door panel may generate relatively high noise due to stick-slip phenomenon or the like due to vibration or force. In order to prevent the occurrence of such abnormal noise, it is conceivable to employ the configuration disclosed in Patent Document 1 at the end of the vehicle door trim. However, in that case, the bead is visually recognized from the gap between the vehicle door trim and the door panel, and there is a concern that the design of the door may deteriorate.

  The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a vehicle door trim mounting structure that can prevent the generation of abnormal noise and maintain design.

  The present invention is a mounting structure of a vehicle door trim to a vehicle door panel, wherein the vehicle door trim has a pointed tip at an end thereof, and the pointed tip forms the tip. The inclined surface inclined from the back surface toward the surface, the obtuse angle part forming an angle where the angle formed by the inclined surface and the back surface is an obtuse angle in cross section, and the angle formed by the inclined surface and the surface is a cross section. An acute angle part that forms an angle that becomes a viewing acute angle, and a round-shaped projecting part that projects from the inclined surface, and the acute angle part and the projecting part are in contact with the door panel, A vehicle door trim is attached to the door panel.

  According to such a vehicle door trim mounting structure, since the acute angle portion is in contact with the door panel, there is no gap between the door trim and the door panel. Then, the interior of the door is not visually recognized, and the design of the door can be maintained. In addition, if the door trim and the door panel move relative to each other due to vibration or force applied to the door, the round-shaped protruding portion will slide even if the tip of the door trim and the door panel rub against each other. You can move on the door panel. Then, it can suppress that abnormal noise generate | occur | produces from the edge part of a door trim.

  The said structure WHEREIN: The said protrusion part shall be provided only in the edge part of the rear side of the said vehicle door trim. The rear side of the door trim is a portion where vibration and force are easily applied when the door is opened and closed and the vehicle travels. However, according to such a mounting structure for a vehicle door trim, since the projecting portion is provided only at the rear end portion of the vehicle door trim, it is possible to efficiently suppress the generation of noise.

  The said structure WHEREIN: The said protrusion part can be made to protrude from the said obtuse angle part. If a relatively strong vibration or force is applied to the end of the door trim, it is conceivable that the obtuse angle part abuts on the door panel and abnormal noise is generated. However, according to such a vehicle door trim mounting structure, since the projecting portion projects from the obtuse angle portion, the obtuse angle portion does not contact the door panel. Therefore, it is possible to prevent the generation of noise due to the obtuse angle portion being rubbed against the door panel.

  In the above configuration, the vehicle door trim includes a main body portion and a standing wall portion erected from the end portion of the main body portion to the outside of the vehicle compartment, and the standing wall portion extends from the main body portion toward the outside of the vehicle compartment. It can stand up in the form which spreads to the side, and the tip can be provided at the tip of the standing wall. According to such a vehicle door trim mounting structure, when vibration or force is applied to the end of the door trim, the end of the door trim bends. And the pointed part provided in the front-end | tip of a standing wall part spreads sideways, and leaves | separates from a main-body part. Then, a round-shaped protrusion having a relatively low frictional force becomes a fulcrum, and an acute angle portion having a relatively high frictional force is separated from the door panel. Thereby, the edge part of a door trim can slide on a door panel smoothly, and it can suppress that an abnormal noise generate | occur | produces from the edge part of a door trim.

  ADVANTAGE OF THE INVENTION According to this invention, while preventing generation | occurrence | production of abnormal noise, it becomes possible to provide the attachment structure of the vehicle door trim which can maintain the designability.

And a pillar 4 extending in the vertical direction. The front door 2 and the rear door 3 are configured such that front end portions thereof are connected to the main body of the vehicle 1 and can be opened and closed with the connecting portion as a fulcrum.

  As shown in FIG. 2, which is a cross-sectional view (cross section taken along the line AA) of the rear end portion of the front door 2, the front door 2 is disposed on the vehicle interior side of the door panel 20. A resin door trim (vehicle door trim) 40. The door panel 20 includes a door outer panel 21 disposed outside the vehicle compartment, and a door inner panel 22 disposed on the vehicle interior side of the door outer panel 21. The door trim 40 is attached to the door inner panel 22 from the vehicle interior side with a clip or the like (not shown).

  The pillar 4 includes a sheet metal pillar panel 30 and a weather strip 31 attached to the front end of the pillar panel 30. As the material of the weather strip 31, an elastic material such as rubber is used. When the front door 2 is opened to the vehicle interior side from the state in which the front door 2 is opened to the vehicle exterior side (see FIG. 4), the rear end portion 41 of the door trim 40 contacts the weather strip 31. As a result, the gap between the front door 2 and the pillar 4 is closed by the weather strip 31, so that water, dust, and the like do not enter the vehicle interior.

  Next, the rear end portion 41 of the door trim 40 in a state where the front door 2 is opened will be described with reference to FIGS. 4 and 5. As shown in FIG. 4, the rear end portion 41 of the door trim 40 has a main body portion 42 extending in the vehicle front-rear direction, and a standing wall portion 43 erected from the end portion of the main body portion 42 outside the vehicle compartment Is arranged. The standing wall portion 43 is erected in a zigzag shape so as to incline toward the rear of the vehicle as it goes from the main body portion 42 toward the outside of the vehicle compartment (in a form spreading to the side).

  The tip of the standing wall 43 is provided with a pointed tip 50 directed toward the outside of the passenger compartment. As shown in FIG. 5, the pointed shape of the pointed portion 50 is formed by the back surface 52, the front surface 53, and the inclined surface 51 inclined from the back surface 52 toward the front surface 53 at the tip of the standing wall portion 43. ing. The inclined surface 51 is inclined toward the rear of the vehicle toward the outside of the passenger compartment.

  The pointed portion 50 has an obtuse angle portion 54 that forms a corner on the outside and the front side of the passenger compartment, and an acute angle portion 55 that forms a corner on the outside and the rear side of the passenger compartment. In the obtuse angle portion 54, the angle θ1 formed by the inclined surface 51 and the back surface 52 is an obtuse angle in cross section. Further, in the acute angle portion 55, the angle θ2 formed by the inclined surface 51 and the surface 53 is an acute angle in sectional view. Therefore, the acute angle portion 55 is sharper toward the outside of the passenger compartment than the obtuse angle portion 54.

  Further, the tip 50 has a protruding portion 56 that protrudes from the inclined surface 51 to the outside of the passenger compartment at the obtuse angle portion 54. As shown in FIG. 6, the protruding portions 56 are provided at a plurality of locations only in the rear end portion 41 of the door trim 40 in the vertical direction. Moreover, the protrusion part 56 is spherical, and as shown in FIG.

  The acute angle portion 55 and the protruding portion 56 are directed toward the vehicle interior outside at the rear end portion 41 of the door trim 40 and are in contact with the door inner panel 22 from the vehicle interior side. In this state, the door trim 40 is attached to the door inner panel 22 from the vehicle interior side.

  Subsequently, the rear end portion 41 of the door trim 40 in a state where the front door 2 is closed will be described with reference to FIGS. 2 and 3. When the front door 2 is opened to the vehicle interior side (see FIG. 4) and the front door 2 is closed to the vehicle interior side, as shown in FIG. It contacts the weather strip 31. Then, the weather strip 31 is dented so as to follow the shape of the rear end portion 41 of the door trim 40 and elastically deforms.

  At this time, the rear end portion 41 of the door trim 40 is bent by receiving a repulsive force from the weather strip 31 as shown in FIG. And the standing wall part 43 which inclines and stands from the main-body part 42 to the vehicle back further inclines to the vehicle back. Then, the acute angle portion 55 is separated from the door inner panel 22 with the protruding portion 56 as a fulcrum.

  Then, the effect of this embodiment is demonstrated. In the present embodiment, the door trim (vehicle door trim) 40 has a pointed tip 50 at the end 41, and the tip 50 extends from the back surface 52 to the surface 53 to form the tip. An inclined surface 51 inclined toward the surface, an obtuse angle portion 54 that forms an angle at which the angle θ1 formed by the inclined surface 51 and the back surface 52 forms an obtuse angle in cross-sectional view, and an angle θ2 formed by the inclined surface 51 and the surface 53 The door trim in a state where the acute angle portion 55 and the protrusion 56 are in contact with the door panel 20. 40 is attached to the door panel 20.

  According to such an attachment structure of the door trim 40, since the acute angle portion 55 is in contact with the door panel 20, no gap is generated between the door trim 40 and the door panel 20. Then, the interior of the front door 2 is not visually recognized, and the design of the front door 2 can be maintained. Further, if the vibration or force is applied to the front door 2, the door trim 40 and the door panel 20 are relatively moved, and the pointed portion 50 and the door panel 20 at the end 41 on the rear side of the door trim 40 are rubbed. Even so, the round projection 56 can move on the door panel 20 so as to slide. Then, it is possible to prevent abnormal noise from being generated from the end portion 41 of the door trim 40.

  In the above configuration, the protrusion 56 is provided only at the end 41 on the rear side of the door trim 40. The rear side of the door trim 40 is a portion where vibration and force are easily applied when the front door 2 is opened and closed or when the vehicle 1 travels. However, according to such an attachment structure of the door trim 40, since the protruding portion 56 is provided only at the end portion 41 on the rear side of the door trim 40, generation of abnormal noise can be efficiently suppressed.

  In the above configuration, the protruding portion 56 protrudes from the obtuse angle portion 54. If relatively strong vibration or force is applied to the rear end portion 41 of the door trim 40, it is conceivable that the obtuse angle portion 54 comes into contact with the door panel 20 and an abnormal noise is generated. However, according to such an attachment structure of the door trim 40, since the protruding portion 56 protrudes from the obtuse angle portion 54, the obtuse angle portion 54 does not contact the door panel 20. Therefore, it can be prevented that the obtuse angle portion 54 is rubbed against the door panel 20 and abnormal noise is generated.

  In the above configuration, the door trim 40 includes a main body portion 42 and a standing wall portion 43 erected from the end portion of the main body portion 42 to the vehicle compartment outer side. The tip 50 is provided at the front end of the standing wall 43. According to such an attachment structure of the door trim 40, when vibration or force is applied to the rear end portion 41 of the door trim 40, the rear end portion 41 of the door trim 40 is bent. Then, the pointed portion 50 provided at the tip of the standing wall portion 43 spreads laterally and moves away from the main body portion 42. Then, the round-shaped protrusion 56 having a relatively low frictional force becomes a fulcrum, and the acute angle portion 55 having a relatively high frictional force is separated from the door panel 20. Accordingly, the rear end portion 41 of the door trim 40 can smoothly slide on the door panel 20, and the generation of abnormal noise from the rear end portion 41 of the door trim 40 can be suppressed.
