  The present invention relates to a vehicle body structure including an instrument panel having an opening through which a shift device is passed.

  An instrument panel, which is an interior part that partitions an engine room and a living space, is mounted on a vehicle such as an automobile.

  Patent Document 1 discloses a vehicle body that employs a so-called instrument panel shift in which an opening is formed in the center portion of an instrument panel (also abbreviated as instrument panel), and a shift device including a shift lever is passed through the opening. A structure is disclosed. The shift device is fixed to a brace of a sheet metal part welded to the steering support member and extending downward.

JP 2009-190497 A

  In general, the shift device has a large shape. For this reason, the opening part of the instrument panel described in Patent Document 1 has a size that matches the shape of the shift device. The instrument panel is made of resin and stored after molding, for example, after being transported from a storage location, it is mounted on the vehicle body.

  The instrument panel having the large opening is easily deformed by a load applied during storage or transportation. When the shift device is assembled to the instrument panel in a state where the opening is deformed, a gap is generated between the instrument panel and the shift device, resulting in poor appearance.

  The shift device is heavy and receives a large operating force (load) because the shift lever is operated by an occupant (driver). For this reason, the shift device is fixed to the brace of the sheet metal part as described in Patent Document 1.

  That is, the shift device is not directly coupled to the instrument panel, and is fixed to a brace that is separated from the design surface of the instrument panel by the thickness of the shift device, that is, deep in the front of the vehicle. . In this state, the shift device may be twisted due to the load accompanying the operation of the shift lever, causing a positional shift between the instrument panel and the shift device, and the gap may be widened, resulting in poor appearance.

  In order to prevent the appearance defect accompanying such a positional shift, a structure for restricting the position of the instrument panel and the shift device is required. However, in a structure that simply restricts the position, the assembly of the instrument panel may be impaired.

  In view of such problems, the present invention provides a vehicle body structure capable of preventing the occurrence of poor appearance by preventing misalignment between the instrument panel and the shift device without impairing the assembling property of the instrument panel. With the goal.

  In order to solve the above problems, a representative configuration of a vehicle body structure according to the present invention is a vehicle body structure including an instrument panel having an opening through which a shift device is passed. A steering support member extending in a direction and fixed at both ends to the vehicle body; and a brace connected to the steering support member and extending downward and fastened to the shift device, wherein the instrument panel is a passenger seat of the shift device. It further has a bridging part that bridges the upper edge and lower edge of the opening by extending downward from the upper edge of the opening to the vehicle front side and returning to the lower edge of the opening, and the bridging part is lowered It has the arm part extended from the part to the shift device side, and fastened to the brace.

  According to the said structure, the opening part of an instrument panel is bridged and reinforced by a bridge part. For this reason, the opening of the instrument panel is difficult to deform, and deformation during transportation or storage is prevented.

  Moreover, according to the said structure, the bridge part of the instrument panel and the shift device are both fastened to the brace. Therefore, the positional relationship between the instrument panel and the shift device is indirectly regulated via the brace. That is, by fastening the bridge portion to the brace, the position of the instrument panel is corrected with respect to the steering support member and is also aligned with the shift device. For this reason, it is hard to produce position shift with the shift device passed through the opening part, and the opening part of an instrument panel, and the appearance defect accompanying position shift does not arise.

  Furthermore, according to the said structure, since an instrument panel has a bridge part fastened by a brace, the assembly | attachment property with respect to a steering support member and a shift device also improves.

  Further, according to the above configuration, the bridging portion is fastened to the brace by the arm portion extending from the “falling portion” that is separated from the opening forward of the vehicle. There is a space between them. For this reason, an appropriate accessory part can be arrange | positioned in this space, and a bridge part can also be used for the clamp and attachment.

  According to the above configuration, since the bridge portion is located on the passenger seat side of the shift device, that is, at a position that is far from the driver who operates the shift device and is susceptible to a load accompanying the operation, the twist of the shift device is caused by the bridge portion. Are also easily absorbed. For this reason, the bridge part located in the passenger seat side of a shift device contributes to prevention of the said position shift.

  The brace is provided between a first fastening point and a second fastening point, which are fastened to the shift device and separated in the vehicle vertical direction, and a first fastening point and a second fastening point, and fastened to an arm part. It is good to have 3 fastening points.

  According to the said structure, a bridge part will be in the state supported by the brace between the two fastening points of the brace which fastens a shift device. For this reason, the twist of the shift device that occurs when the shift device is operated by the driver is absorbed not only by the brace but also by the bridge portion. Therefore, it is possible to prevent the shift device from being twisted and to prevent the shift device and the instrument panel from being displaced due to the twist.

  The bridge part of said instrument panel is good to further have the flange erected along the edge by the side of a shift device.

  According to the above configuration, the bridge portion has the flange in addition to being fastened to the brace, so that the shift device can be reinforced in the torsion direction, and torsion is prevented.

  Moreover, according to the said structure, since the flange was formed only in the edge part used as the shift device side, a flange will exist only in the one side of a bridge part, and the structure of a shaping die can be simplified.

  If the flanges are formed on both sides of the bridge portion, the mold between the flanges on both sides becomes a tapered shape. In this case, by repeatedly using the mold, it becomes difficult to perform stable mold formation such as scratches. On the other hand, according to the above configuration in which the flange is formed only on one side of the bridge portion, it is possible to prevent the mold from becoming a tapered shape and to stably mold the mold.

  Said flange is good to stand upright inclined so that the front-end | tip may approach a shift device. According to the said structure, when attaching the instrument panel which has a bridge part with respect to the steering support member to which the shift device was fastened, a flange functions as a guide and it can improve assembly property.

The brace 126 includes a fastening point 128c (first fastening point) and a fastening point 128d (second fastening point) that are separated from each other in the vehicle vertical direction, and a fastening point that is located approximately in the middle between the fastening point 128c and the fastening point 128d. 128e (third fastening point) is formed. The fastening point 128e is used when fastening the bridging portion 140 to the brace 126.

  The bridge portion 140 is integrally formed with the instrument panel 110 using a mold, and has a shape that bridges the opening 112 and between the opening 112 and the brace 126. The bridge 140 is located on the passenger seat side of the shift device 130 in the state shown in FIG. 1 in which the shift device 130 is passed through the opening 112.

  As shown in FIG. 2B, the bridge part 140 includes an upper extension part 142, a lower extension part 144, a connecting part 146, and an arm part 148. Note that an arrow S in the figure indicates the shift device 130 side. As shown in FIG. 3, the upper extension 142 extends from the upper edge (upper side 114) of the opening 112 toward the brace 126 (see FIG. 2A) toward the front of the vehicle. The lower extension 144 extends from the lower edge (lower side 116) of the opening 112 toward the brace 126 toward the front side of the vehicle. The connecting portion 146 connects the upper extension portion 142 and the lower extension portion 144 and extends in the vehicle vertical direction.

  That is, the bridging portion 140 extends downward from the upper side portion 114 of the opening 112 to the front of the vehicle on the passenger seat side of the shift device 130 and returns to the lower side portion 116 of the opening 112 so that Bridge the lower side portion 116. Note that the descending portion of the bridge portion corresponds to the connecting portion 146.

  Further, as shown in FIGS. 2B and 3, the arm portion 148 of the bridging portion 140 extends from the connecting portion 146, that is, the “part to be lowered” to the shift device 130 side, and has a hole 150. The hole 150 is used when the bridge 140 is fastened to the brace 126 together with the fastening point 128e of the brace 126.

  That is, a fastening member such as a screw 152 (see FIG. 5) is inserted into the hole 150 in a state of being superimposed on the fastening point 128e of the brace 126. In this way, the bridge panel 140 is fastened to the brace 126, whereby the instrument panel 110 is assembled to the integrated shift device 130 and the steering support member 120.

  Moreover, as shown in FIG.2 (b), the flange is formed in the bridge part 140 along the edge part by the side of the shift device 130. As shown in FIG. That is, the upper extension 142 and the lower extension 144 have flanges 142b and 144b formed along the respective edges 142a and 144a.

  The connecting portion 146 includes flanges 146 c and 146 d formed along the respective edge portions 146 a and 146 b located between the upper extension portion 142 and the arm portion 148 and between the lower extension portion 144 and the arm portion 148. Have. The arm portion 148 has opposing flanges 148b and 148c formed along the edge portion 148a and a flange 148e positioned at the tip 148d on the shift device 130 side.

  Further, as shown in FIG. 3, the bridging portion 140 defines a space 160 with an upper extension 142 and a lower extension 144 that extend to the front side of the vehicle and a connecting portion 146 that connects them. The space 160 and the bridge portion 140 may be used, for example, for attaching a harness clamp or sensors.

  Hereinafter, the vehicle body structure 100 in a state where the instrument panel 110 is assembled to the integrated shift device 130 and the steering support member 120 will be described with reference to FIGS.

  FIG. 4 is a diagram showing a state in which the vehicle body structure 100 of FIG. 1 is viewed from the vehicle rear side. 5 is a cross-sectional view taken along the line CC of the vehicle body structure 100 of FIG. 6 is a DD cross-sectional view of the vehicle body structure 100 of FIG. FIG. 6A is a DD cross section of the vehicle body structure 100, and the lower side in the figure is shown as the vehicle front side. FIG. 6B is an enlarged view of a part of FIG.

  In the vehicle body structure 100, as shown in FIG. 5, the upper side 114 and the lower side 116 of the opening 112 are bridged by the upper extension 142, the connecting part 146, and the lower extension 144 of the bridge part 140. Further, the bridge portion 140 is fastened to the brace 126 by inserting the screw 152 into the hole 150 of the arm portion 148 extending from the connecting portion 146 and the fastening point 128 e of the brace 126. Further, in order to avoid the head portion of the screw 152 coming into contact with the shift device 130, the periphery of the hole 150 and the fastening point 128e in the figure has a shape recessed toward the front side of the vehicle.

  By the way, as shown in FIG. 4, the opening 112 of the instrument panel 110 needs to pass through the shift device 130 having a large shape, so that the opening 112 is large in accordance with the shape of the shift device 130. In such an instrument panel 110, the opening 112 is easily deformed by a load applied during storage after molding or during transportation.

  On the other hand, in the vehicle body structure 100, since the opening 112 of the instrument panel 110 is bridged and reinforced by the bridge 140, the opening 112 is difficult to deform. Therefore, in the vehicle body structure 100, in a state where the shift device 130 is passed through the opening 112 of the instrument panel 110, a gap with the shift device 130 due to the deformation of the opening 112 of the instrument panel 110 is hardly generated. The occurrence of poor appearance can be reduced.

  Further, in the vehicle body structure 100, since the bridge portion 140 and the shift device 130 of the instrument panel 110 are both fastened to the brace 126, the positional relationship between the instrument panel 110 and the shift device 130 is determined via the brace 126. Regulated indirectly. That is, the position of the resin instrument panel 110 is corrected with respect to the steering support member 120 that is a sheet metal part, and as a result, the resin instrument panel 110 is also aligned with the shift device 130.

  In addition, if the structure which directly couple | bonds the shift device 130 and the instrument panel 110 and performs position control is employ | adopted, when a position error arises between the steering support member 120 and the shift device 130, an instrument panel will be provided. The position of the shift device 130 with respect to 110 shifts. As a result, for example, the position of a hole or the like for inserting the fastening member is shifted, and it becomes difficult to assemble the instrument panel 110, and the assembling property is impaired.

  On the other hand, in the vehicle body structure 100, the shift device 130 passed through the opening 112 is not directly coupled to the shift device 130 and the instrument panel 110 but indirectly regulated via the brace 126. And the position shift with the opening part 112 of the instrument panel 110 does not arise easily, and the external appearance defect accompanying a position shift does not arise. Further, in the vehicle body structure 100, since the bridge portion 140 of the instrument panel 110 and the shift device 130 are both fastened to the brace 126, even if a position error occurs between the steering support member 120 and the shift device 130, The assembling property of the instrument panel 110 is not impaired.

  Further, in the vehicle body structure 100, as shown in FIG. 4, the bridge portion 140 is located on the passenger seat side of the shift device 130. Note that the passenger seat side of the shift device 130 is a position that is far from the driver who operates the shift device 130 and is susceptible to a load associated with the operation. For this reason, the shift device 130 is likely to be twisted in the direction indicated by the chain line E in the figure. In the vehicle body structure 100, since the bridging portion 140 is set on the passenger seat side of the shift device 130, the twist of the shift device 130 can be absorbed also by the bridging portion 140, and the above-described displacement due to the twist can be reduced.

  Further, in the vehicle body structure 100, as shown in FIG. 4, at the fastening point 128e located near the middle of the two fastening points 128c and 128d for fastening the shift device 130, the arm portion 148 of the bridge portion 140 and the brace 126 are provided. And are concluded. That is, the bridge portion 140 of the instrument panel 110 is supported by the brace 126 near the middle between the fastening points 128 c and 128 d that support the shift device 130. For this reason, in the vehicle body structure 100, the torsion of the shift device 130 is easily absorbed not only by the brace 126 but also by the bridge portion 140, and the torsion of the shift device 130 can be reduced and the displacement can be prevented.

  Further, in the vehicle body structure 100, not only the bridging portion 140 is fastened to the brace 126, but also the flanges 142b, 144b, 146c, and 146d on the shift device 130 side of the bridging portion 140 as shown in FIG. 148b, 148c, and 148e are formed. For this reason, in the vehicle body structure 100, the bridging portion 140 is reinforced with respect to the twisting direction of the shift device 130, and twisting is further prevented. Thus, the vehicle body structure 100 has a strength that can withstand the twist of the shift device 130.

  Moreover, since each flange 142b, 144b, 146c, 146d, 148b, 148c, 148e is formed only on the shift device 130 side of the bridge portion 140, that is, on one side, the structure of the molding die can be simplified and stable. Molding becomes possible. If flanges are formed on both sides of the bridge portion 140, the mold between the flanges on both sides becomes a tapered shape, and repeated use of the mold makes it difficult to perform stable mold formation such as scratches. In addition, although a metal mold | die becomes thin only between the flanges 148b and 148c which the arm part 148 of the bridge part 140 opposes, it is only necessary to extend a metal mold | die corresponding to the arm part 148, and a stable metal mold | die shaping | molding is carried out. There is no loss.

  Furthermore, in the vehicle body structure 100, as shown in the DD cross section of FIG. 6, the flange 146c of the bridging portion 140 is positioned closer to the shift device 130 toward the tip 146e from the edge 146a, that is, the shift device 130. Inclining and projecting so as to approach the support portion 134c. Here, an insertion hole 154 is formed in the support portion 134c of the shift device 130 as shown in FIG. The support portion 134c is fixed to the brace 126 by inserting a bolt 156 indicated by an imaginary line in a state where the fastening point 128c of the brace 126 and the insertion hole 154 are overlapped, and further fastening by a nut 158. . The other flanges 146d and 148e are similarly inclined toward the shift device 130.

  Therefore, in the vehicle body structure 100, when the instrument panel 110 having the bridge portion 140 is attached to the steering support member 120 to which the shift device 130 is fastened, the flanges 146c, 146d, and 148e inclined toward the shift device 130 are provided. It functions as a guide and can improve assemblability.

  In particular, the shift device 130 protrudes toward the occupant side of the instrument panel 110 and is often provided on the design surface farthest from the steering support member 120. For this reason, assembling property is not impaired by forming the flanges 146c, 146d, and 148e inclined as described above, which serve as a guide for assembly, in the bridge portion 140 of the instrument panel 110.

  Therefore, according to the vehicle body structure 100, it is possible to prevent occurrence of poor appearance by preventing misalignment between the instrument panel 110 and the shift device 130 without impairing the assembling property of the instrument panel 110.

  In the above embodiment, as shown in FIG. 2C or 6, the bridging portion 140 has an inclined shape in which at least the flanges 146 c, 146 d, and 148 e formed on the edge portion on the shift device 130 side face the shift device 130. However, the present invention is not limited to this. That is, when assembling the instrument panel 110, the operator needs to overlap the hole portion 150 of the bridge portion 140 at the fastening point 128e located between the two fastening points 128c and 128d. For this reason, it is important that the tip 148d of the arm portion 148 of the bridge portion 140 functions as a guide, and only the flange 148e of the arm portion 148 may have an inclined shape and function as a guide.

  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 vehicle body structure including an instrument panel having an opening through which a shift device is passed.
