Description

  The present invention relates to a door structure of a vehicle door, and more particularly to an internal structure of an interior material.

  Generally, a resin interior material called a door trim is attached to the inside of a vehicle door. The door trim is provided with a door inside handle for an occupant to open and close the door.

  The door lock mechanism is provided near the center pillar of the door (the rear end of the door). The door outside handle disposed outside the door is provided near the door lock mechanism, and the door outside handle and the door lock mechanism are connected by a rigid rod. However, if the door inside handle is provided in the vicinity of the door lock mechanism, the door inside handle is disposed beside the occupant, and is too close to be operated easily. For this reason, since there is a distance between the door inside handle and the door lock mechanism, they are connected by a cable.

  When this cable swings inside the door due to the vibration of the vehicle and collides with the surroundings, an abnormal noise is generated. Although it cannot be so loud, it still occurs near the occupant and may cause discomfort. Therefore, it is necessary to suppress the swing of the cable.

  Therefore, the cable is fixed by being sandwiched between the door panel and the door trim, and the swing is suppressed. However, both the door panel and the door trim are undulating members, and there are portions where the door panel cannot secure a mutual clearance (gap) due to structural reasons and the door trim due to design and functional reasons. For this reason, it is difficult to properly sandwich the cable over the entire area of the cable.

  Therefore, in a portion where an appropriate clearance cannot be secured between the door panel and the door trim, a protrusion is provided on the back side of the door trim, and the cable is sandwiched between the protrusion and the door panel. As a result, the cable can be prevented from swinging due to vibration during travel, and abnormal noise can be prevented.

  Patent Document 1 proposes a structure in which a plurality of bosses to be attached to a door inner panel are provided on a door trim, and a door operation cable is fixed to one of the bosses. Patent Document 1 is not intended to prevent abnormal noise, but aims to suppress interference between the boss and the cable when the door trim is attached to the door inner panel. It is thought that the occurrence can also be prevented.

JP 2006-290256 A

  As in the structure of Patent Document 1, in order to fix the cable, it is easy to fix the door trim by providing a protrusion. However, in order to hold the cable toward the door panel, it is necessary to project a rib that is somewhat high. If a protrusion such as a boss is provided on the back side in injection molding, sink marks and flow marks may be generated on the front side, which is the design surface, and the appearance may be impaired.

  Note that sink marks are molding defects that shrink when the resin cools and hardens and the back side of protrusions such as bosses is dented. The flow mark is a molding defect in which a stripe pattern is generated due to uneven or stagnant resin flow. Both have the property of being more likely to occur as the volume (volume) of a three-dimensional shape such as a boss increases.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a door structure in which a protrusion is provided on the back side of a door trim that suppresses the swing of a door operation cable without causing an appearance defect.

  In order to solve the above-described problems, a typical structure of a door structure according to the present invention includes a door panel, a door trim attached to the inside of the door panel as an interior of a vehicle door, and a decorative surface provided on a design surface of the door trim. A groove portion and a protruding portion provided on the back side of the groove portion are provided, and a cable disposed between the door trim and the door panel is sandwiched and fixed between the protruding portion and the door panel.

  According to the said structure, even if a sink mark and a flow mark generate | occur | produce due to a protrusion part by providing the protrusion part for suppressing a cable in the back side of a groove part, it generate | occur | produces in the back of a groove part. For this reason, sink marks are extremely difficult to be observed from the design surface, so that appearance defects do not occur. In addition, since the rear side of the groove protrudes toward the door panel, the height of the protrusion for restraining the cable can be kept low compared to the case where the protrusion is provided in another part, greatly increasing the weight. Can be reduced.

  As the cable, in particular, a cable connected from the door inside handle to the door lock mechanism can be targeted. As another example, an electric cable connected to a door mirror winker, an electric cable of a power window, etc. Can do. However, since the cable of the door lock mechanism is particularly heavy and easily generates abnormal noise, there is an advantage in applying the present invention.

  It is preferable to further include a decorative outer surface pasted on the design surface of the door trim, and to bury the end of the outer surface in the groove. As a result, the inside of the groove is filled with the edge of the outer material. Therefore, even if sink marks are generated at the back of the groove portion, they are not observed at all, and thus there is no possibility of causing poor appearance. Further, the edge of the outer surface can be processed at the same time, and the appearance can be easily improved.

  ADVANTAGE OF THE INVENTION According to this invention, the door structure which provided the protrusion part which suppresses rocking | fluctuation of the cable for door operation on the back side of a door trim can be provided, without producing an external appearance defect.

It is a disassembled perspective view of the door structure of a vehicle door. It is a figure explaining the vicinity of a retreat part. It is a figure which shows the back side of a door trim. It is a figure explaining the vicinity of the retreating part concerning a 2nd embodiment.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

[First Embodiment]
FIG. 1 is an exploded perspective view of a door structure of a vehicle door. In FIG. 1, the left side is the front of the vehicle. The vehicle door 100 includes a door panel 102 made of a steel plate and a resin door trim 120. The door panel 102 includes a door outer panel 104 that forms an outer plate of the vehicle, and a door inner panel 106 that is combined with the door outer panel 104 to improve strength.

  A door lock mechanism 110 is attached between the door outer panel 104 and the door inner panel 106. The door lock mechanism 110 is configured to expose the latch 110a on the end face of the door panel 102 and engage with a striker (not shown) provided on the center pillar.

  A door outside handle 112 is attached to the outside of the door outer panel 104. The door outside handle 112 is disposed near and substantially above the door lock mechanism 110, and the door outside handle 112 and the door lock mechanism 110 are connected by a door opening / closing rod 110b and a locking operation rod 110c. ing.

  A door inside handle 114 is attached to the inside of the door inner panel 106. The door inside handle 114 is disposed closer to the front of the vehicle than the door lock mechanism 110 so as to be easily operated by the occupant. In the example of FIG. 1, the door inside handle 114 is fixed substantially at the center near the upper edge of the door panel 102. Thus, since the door inside handle 114 and the door lock mechanism 110 have a distance, they are connected by a door opening / closing cable 110d and a locking operation cable 110e. The cables 110d and 110e have a double structure in which an inner wire is passed through an outer cable so that both pushing and pulling can be performed.

  As shown by broken lines in FIG. 1, the cables 110 d and 110 e pass from the door lock mechanism 110 between the door outer panel 104 and the door inner panel 106 through the opening 106 a provided in the door inner panel 106 to the door. It is connected to a door inside handle 114 attached to the inner side of the inner panel 106. Therefore, the cables 110d and 110e can be prevented from swinging if the vicinity of the edge of the opening 106a is fixed by the door trim 120 and the door inner panel 106.

  The door trim 120 is an interior of the vehicle door 100 and is attached to the inside of the door panel 102. The door trim 120 is made of resin and is manufactured by injection molding. The door trim 120 is provided with a three-dimensional structure such as a handle opening 122 for exposing the door inside handle 114, an armrest 124, and a pocket 126. The armrest 124 is raised on the inner side of the vehicle, and a retreating part 128 that is depressed on the outer side of the vehicle is provided on the upper side of the armrest 124.

  FIG. 2 is a view for explaining the vicinity of the retreating portion 128. As shown in FIG. 2 (a), the retreating part 128 is provided so that the occupant can easily use the armrest 124 by placing the upper arm in the retreated space. Accordingly, the periphery of the receding portion 128 is generally a convex curve, whereas the receding portion 128 is a concave curve. In the present embodiment, the groove 130 is formed at the boundary of the receding portion 128.

  FIG.2 (b) is AA sectional drawing of Fig.2 (a). The groove 130 is provided on the design surface of the door trim 120 for decoration. When the groove 130 is provided, the back side of the groove 130 protrudes toward the door inner panel 106.

  Further, a rib 132 is formed at the apex of the back surface 130a of the groove. The ribs 132 are protrusions that stand along the ridgeline of the back surface 130a of the groove. The rib 132 can ensure (adjust) a clearance (gap) between the door trim 120 and the door inner panel 106. Accordingly, the cables 110d and 110e can be appropriately sandwiched and fixed.

  3 is a view showing the back side of the door trim 120, FIG. 3 (a) is a view showing the entire door trim 120, and FIG. 3 (b) is an enlarged view of a portion surrounded by a broken line in FIG. 3 (a). . The rib 132 is provided on the back surface 130a of the groove portion. However, the rib 132 does not need to be provided over the entire length, and may be long enough to fix the cable. Therefore, in this embodiment, the rib 132 is provided only in the site | part corresponding to the position where the cables 110d and 110e shown with the broken line in FIG. 1 pass.

  According to the above configuration, the rib 132 for suppressing the cables 110d and 110e is provided on the back surface 130a of the groove portion, so that even if sink marks or flow marks are generated due to the rib 132, they are generated at the back of the groove portion 130. . For this reason, sink marks are extremely difficult to be observed from the design surface, so that appearance defects do not occur. Further, since the back surface 130a of the groove portion protrudes toward the door panel 102 (door inner panel 106), the height of the rib 132 for suppressing the cables 110d and 110e is higher than that in the case where the rib 132 is provided at another portion. It can be kept low, and the weight increase can be greatly reduced.

  In the first embodiment, the groove portion 130 is described as being provided at the boundary of the receding portion 128 having a functional shape although it is for decoration. However, the present invention is not limited to this, and the groove portion may be arranged only for decoration without depending on the functional shape. In this case, since it is more flexible to design the groove 130 to pass through the part where the cables 110d and 110e need to be fixed, the boundary of the functional shape is higher than that in the part. It is possible to fix with.

  Moreover, in the said embodiment, although demonstrated that the cable connected to a door lock mechanism from a door inside handle was fixed by a protrusion part, the electric cable connected to a door mirror turn signal, the electric cable of a power window, etc. are the same. You may fix to a protrusion by. In this case, the position of the protruding portion can be set as appropriate according to the position through which the cable or wiring passes.

[Second Embodiment]
A second embodiment of the door structure according to the present invention will be described. FIGS. 4A and 4B are diagrams for explaining the vicinity of the retreating portion 128 according to the second embodiment. FIG. 4A is a partial perspective view, and FIG. 4B is a cross-sectional view taken along line BB in FIG. is there. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  Conventionally, a surface material (fabric) such as cloth or leather is pasted on the interior of a vehicle to improve the appearance and touch. Further, in recent years, a surface material has been disposed only on a part of the door trim 120.

  In this embodiment, in addition to the first embodiment, a decorative material 140 such as cloth or leather is pasted and decorated. The area to be decorated can be determined arbitrarily, but in this embodiment, the receding portion 128, that is, the area surrounded by the groove 130 (the area hatched in FIG. 4A) is pasted on the outer surface 140. The decoration part. In FIG. 4 (a), the receding portion 128 and the outer surface 140 overlap, so refer to FIG. 4 (b) for the structure.

  As a characteristic point, the process is performed by embedding the end 140a of the outer material in the groove 130. The outer material 140 is bonded to the inside of the receding portion 128 and the groove portion 130. By such a so-called graining method, the end 140a of the outer material can be hidden, and the appearance can be further improved.

  Further, since the inside of the groove portion 130 is covered with the outer edge 140a, even if sink marks or flow marks due to the ribs 132 are generated in the depth of the groove portion 130, they are not observed at all. This eliminates the possibility of further appearance defects.

  The rib 132 does not necessarily have to be provided on the back side of the groove portion 130 at the boundary of the region to which the surface material 140 is applied, and a groove portion for decoration is provided outside the region to which the surface material 140 is applied, and the rib ( (Projection) may be provided.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used as a door structure of a vehicle door, particularly as an internal structure of an interior material.
