Description

  The present invention relates to a vehicle rear structure including a harness grommet that protects a wire harness between a vehicle body panel and a back door.

  A back door is installed at the rear of a vehicle such as an automobile. A wire harness (hereinafter referred to as a harness) is laid, for example, from a vehicle body panel (for example, a roof panel) constituting the vehicle body inside the back door. A portion of the harness that is positioned between the vehicle body panel and the back door is exposed to the outside when the back door is opened and closed, and thus is protected by a harness grommet (for example, Patent Document 1).

  Patent Document 1 describes a harness grommet including a vehicle-side mounting portion that is locked in a through hole on the vehicle body panel side, and a door-side mounting portion that is locked in a through hole on the back door side. These mounting portions are provided with resin inners formed with locking projections for locking in the respective through holes.

JP 2001-97145 A

  By the way, a vehicle is known in which a roof end spoiler (hereinafter referred to as a spoiler) is attached to the outside of the back door. In such a vehicle assembly process, for example, there is a concern that the spoiler may be damaged during various operations in a factory. For this reason, the spoiler mounting operation is performed in the latter half of the assembly process.

  On the other hand, the work of laying the harness inside the back door is performed before assembling other outfitting parts in consideration of work efficiency, that is, at the beginning of the assembly process. The back door has an internal space defined by an inner panel and an outer panel in which an opening is formed. The harness is introduced and laid inside the back door through the opening of the inner panel.

  Further, in the vehicle assembly process, for example, an operation of attaching the back door glass by fully closing the back door is performed between the harness installation operation and the spoiler installation operation. In this operation, the harness grommet needs to be securely fixed to the opening of the inner panel so that the harness is not caught and damaged when the back door is closed.

  That is, in the above assembly process, the harness grommet is securely fixed after the harness laying operation, and then the back door glass is attached. Thereafter, when the spoiler is attached in the latter half of the assembly process, it is necessary to remove the already fixed harness grommet from the opening of the inner panel.

  Then, with the harness grommet removed, a fixing means such as a bolt is inserted through the opening to fix the spoiler, and the harness grommet is fixed again, thereby completing the spoiler mounting operation. Thus, in the assembly process, it is necessary to fix the harness grommet twice, and work efficiency is impaired.

  Although it is conceivable to form other holes for assembling the spoiler in the inner panel, the formation of the holes reduces the rigidity of the inner panel, and after attaching the spoiler, A separate process for covering the part is required.

  In the harness grommet described in Patent Document 1, no measures have been taken with regard to simply attaching the harness grommet and the spoiler in the vehicle assembly process.

Thereby, the position of a harness and a harness grommet can be stabilized temporarily, a harness and a harness grommet do not become obstructive by various operations performed after that, and work is easy.

  Further, the opening is not blocked while being temporarily mounted by the temporary mounting portion. For this reason, after passing through various operations, a fixing means such as a bolt and a tool for fastening the fastening means are inserted into the opening located at a position overlapping the spoiler, and the fixing means is fastened to complete the spoiler mounting work. Subsequently, the provisional mounting portion is removed from the edge of the opening, and the mounting portion is mounted on the opening so as to close the opening, thereby completing the attaching operation of the harness grommet.

  As described above, in the above configuration, the opening of the inner panel is used not only for the introduction of the harness but also for the attachment work of the spoiler, and in addition, the opening is not closed in various work, and the mounting part is closed so as to close the opening. The work for fixing the to the opening is only once. Therefore, according to the said structure, it becomes possible to perform the attachment work of a harness grommet and a spoiler easily.

  Further, since only one opening portion of the inner panel is required, there is no need to form another hole for attaching a spoiler, for example. Therefore, according to the said structure, since the rigidity of the inner panel of a back door is not impaired and another hole part is unnecessary, manufacturing cost can also be reduced that much.

  The mounting portion includes a disk that closes the opening, an insertion hole that is positioned approximately at the center of the disk and through which the harness is inserted, a wall that is erected around the insertion hole, and a base of the outer periphery of the wall And a first groove portion that engages with an edge of the opening portion and attaches the attachment portion to the opening portion, and the temporary attachment portion is preferably provided at a position closer to the insertion hole than the first groove portion.

  Next, an assembly process in the vehicle rear portion structure 100 will be described. In the assembly process, the harness 108 inserted into the harness grommet 110 is inserted into the opening 116 of the inner panel 118 of the back door 104, and the mounting portion 126 is opened by the temporary mounting portion 142 as shown in FIGS. Temporarily attached to the edge 134 of the portion 116. By temporarily mounting the mounting part 126 of the harness grommet 110, the positions of the harness 108 and the harness grommet 110 can be temporarily stabilized. For this reason, the harness 108 and the harness grommet 110 do not get in the way in various operations performed thereafter, and workability is not impaired.

  Various processes include an operation of fully closing the back door 104 and attaching a back door glass (not shown). During this operation, the mounting portion 126 is temporarily mounted in the opening 116, and the positions of the harness 108 and the harness grommet 110 are stable, so that the harness 108 is not caught and damaged when the back door 104 is closed. .

  After various operations, the bolt 122 and a fastening tool are inserted through the opening 116, the bolt 122 is fastened, and the spoiler 106 is fixed to the back door 104. Subsequently, the temporary attachment portion 142 of the harness grommet 110 is removed from the edge 134 of the opening portion 116 and the attachment portion 126 is attached to the opening portion 116, thereby completing the attaching operation of the harness grommet 110 and the spoiler 106.

  FIG. 5 is an exploded view of a part of the vehicle rear structure 100A of the comparative example. FIG. 6 is an exploded view of a part of a vehicle rear structure 100B of another comparative example. 5A and 6 are shown in correspondence with the exploded view shown in FIG. FIG. 5B shows the harness grommet 110A shown in FIG. 5A, corresponding to FIG. In the figure, the same members as those in the vehicle rear structure 100 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The vehicle rear structure 100A of the comparative example differs from the vehicle rear structure 100 in that the temporary mounting portion 142 is not provided in the mounting portion 126A of the harness grommet 110A as shown in FIG.

  Here, the assembly process in the vehicle rear portion structure 100A will be described. First, the harness 108 inserted into the harness grommet 110 </ b> A is laid inside the back door 104 through the opening 116 of the inner panel 118. Thereafter, as various operations, for example, the operation of attaching the back door glass by fully closing the back door 104 is performed. In this operation, the harness grommet 110 </ b> A is securely fixed to the opening 116 of the inner panel 118 so that the harness 108 is not caught and damaged when the back door 104 is closed.

  Subsequently, the spoiler 106 is attached in the latter half of the assembly process. However, in attaching the spoiler 106, it is necessary to remove the already fixed harness grommet 110A from the opening 116 of the inner panel 118.

  Therefore, the harness grommet 110A is removed from the opening 116 (see FIG. 5A), the bolt 122 is inserted through the opening 116 to fix the spoiler 106, and the harness grommet 110A is fixed again. In this way, the attachment work of the spoiler 106 is completed.

  Therefore, in the assembly process in the vehicle rear structure 100A of the comparative example, it is necessary to fix the harness grommet 110A twice, and work efficiency is impaired. In the vehicle rear structure 100A, the back door 104 may be carefully opened and closed so as not to damage the harness 108 during the back door glass mounting operation, but the work efficiency is reduced.

  The vehicle rear part structure 100B of the comparative example has another hole 152 formed in the inner panel 118A of the back door 104 in addition to the opening 116, and the temporary mounting part 142 in the mounting part 126B of the harness grommet 110B. This is different from the vehicle rear structure 100 in that is not formed.

  In the vehicle rear structure 100B, if the harness grommet 110B is securely fixed to the opening 116 of the inner panel 118A after the harness 108 is laid, unlike the vehicle rear structure 100A of the comparative example, the subsequent steps from the opening 116 It is not necessary to remove the harness grommet 110B. Further, the spoiler 106 may be attached by inserting the bolt 122 into the other hole 152 of the inner panel 118A and fixing it.

  However, in the vehicle rear structure 100B, not only the large-diameter opening 116 but also the dedicated hole 152 for attaching the spoiler 106 is provided in the inner panel 118, so that the rigidity of the inner panel 118A is lowered. Moreover, in the attachment work of the spoiler 106, for example, another process of covering the hole 152 with the cap 154 or the like is required. Furthermore, since the hole 152 is formed and the cap 154 is required, the manufacturing cost also increases.

  On the other hand, in the vehicle rear structure 100 according to this embodiment, as described above, the attachment work of the harness grommet 110 and the spoiler 106 can be performed using the single opening 116, and in addition, the edge 134 of the opening 116. Since the mounting portion 126 can be temporarily mounted on the head, work efficiency can be improved. In addition, since each opening operation uses the opening 116, it is not necessary to form the other hole 152 in the inner panel 118. For this reason, the rigidity of the inner panel 118 of the back door 104 is not impaired. Furthermore, since the hole 152 and the cap 154 for attaching the spoiler 106 are not necessary, the manufacturing cost can be reduced.

  Further, as described above, the temporary attachment portion 142 is provided at a position closer to the insertion hole 136 than the first groove portion 140 for attaching the attachment portion 126 to the opening 116. Therefore, in the operation of removing the temporarily mounted mounting portion 126 from the edge 134 of the opening 116 and finally fixing the mounting portion 126 to the opening 116 using the first groove 140, the temporary mounting portion 142 is mounted. It is located on the center side (inside) from the first groove 140 of the portion 126. Therefore, this work is not hindered by the temporary mounting portion 142, and workability is not impaired.

  Further, as described above, the temporary mounting portion 142 temporarily mounts the mounting portion 126 by the second groove portion 148 that opens toward the center of the mounting portion 126. Therefore, the opening 116 is not blocked by the mounting portion 126, and a sufficient opening area can be secured (see FIG. 4). Therefore, in the spoiler mounting operation, the bolt 122 and the tool for fastening the bolt 122 can be easily inserted into the opening 116, and workability is not impaired.

  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 for a vehicle rear structure including a harness grommet that protects a wire harness between a vehicle body panel and a back door.
