Description

  The present invention relates to a structure for attaching an indoor unit arranged in a vehicle compartment to a vehicle body panel.

  In a vehicle room of an automobile or the like, there are indoor fixtures that need to be fixed to the vehicle body side, such as a belt anchor device and a vehicle seat device. Such an indoor fixture mounting portion is required to have durability against repeated vibration during traveling, strength to avoid interference with other components, passengers, and the like during a vehicle collision. In particular, the belt anchor device needs to satisfy the predetermined safety by accurately restraining the occupant moving forward in the event of a vehicle collision to the seat side, so of course it is necessary to firmly fix it to the vehicle body panel side. It is desirable to suppress the deformation of the vehicle body panel that causes the mounting portion to move greatly.

As a structure that suppresses the movement of the mounting portion at the time of a vehicle collision, a structure in which a bent portion that is bent by a load at the time of a collision is formed on a vehicle body panel is known (for example, see Patent Document 1). According to the structure described in Patent Document 1, by actively setting the vehicle body panel to the intended deformation mode at the time of a collision, the deformation of the fragile portion of the vehicle body panel is prevented and the deformation of the vehicle body panel is suppressed as a whole. It is like that.

  By the way, the rear quarter panel and the side member often have a structure in which a closed body is formed by welding a substantially hat-shaped second vehicle body panel to the substantially flat first vehicle body panel by spot welding or the like. However, when the indoor unit is attached in the vicinity of the closed cross section of the first vehicle body panel, the first vehicle body panel and the second vehicle body panel are deformed independently of each other. Peeling occurs at the welded part. As a result, the strength and rigidity of the vehicle body panel are remarkably reduced, and the vehicle body panel itself may be greatly deformed to move the mounting portion of the indoor unit greatly.

  The present invention has been made in view of the above circumstances, and its object is to fix an indoor unit in the vicinity of a closed cross section formed by welding a second vehicle body panel to a substantially flat first vehicle body panel. In such a case, an object of the present invention is to provide a vehicular indoor unit mounting structure capable of suppressing the peeling of each vehicle body panel due to a load from the indoor unit during a vehicle collision.

  In order to achieve the above object, according to the first aspect of the present invention, a second vehicle body panel is welded to a substantially flat first vehicle body panel to form a closed cross section, and the first vehicle body panel is in the vicinity of the closed cross section. In the vehicle indoor unit mounting structure to which the indoor unit is mounted, a hole is provided in the closed cross-section forming portion of the first vehicle body panel in response to a load applied from the indoor unit in the event of a vehicle collision. To do.

According to the first aspect of the present invention, when a load is applied to each vehicle body panel from the indoor unit at the time of a vehicle collision, first, the periphery of the hole of the first vehicle body panel is deformed. Thus, since the load is received by the first vehicle body panel, the first vehicle body panel is deformed following the deformation of the second vehicle body panel. Therefore, an excessive load in the peeling direction does not act on the welded portion of each panel, and peeling of each vehicle body panel can be suppressed by a load from the indoor equipment at the time of a vehicle collision, and the amount of movement of the indoor equipment is reduced. can do.
At this time, it is preferable that the periphery of the hole in the first vehicle body panel is configured to be deformed toward the second vehicle body panel so that the welded portions of the panels are pressed against each other.

  According to a second aspect of the present invention, in the vehicular indoor unit mounting structure according to the first aspect, the indoor unit is a belt anchor device, and the first vehicle body panel is a rear quarter panel.

  According to the second aspect of the present invention, in addition to the operation of the first aspect, the movement amount of the belt anchor device of the seat belt can be reduced, and the safety of the occupant at the time of the vehicle collision can be improved.

  According to a third aspect of the present invention, in the vehicle interior fitting mounting structure according to the first or second aspect, the first vehicle body panel and the second vehicle body panel are welded by spot welding at a plurality of hit points, and the hole portion Is formed in the vicinity of at least one spot of spot welding.

  According to the third aspect of the invention, in addition to the action of the first or second aspect, the hole is formed in the vicinity of the spot welding spot, so that the separation of the welded portion can be effectively suppressed. At this time, it is preferable to form the hole corresponding to the hit point to which a relatively large load is applied among the hit points.

  As described above, according to the present invention, when the indoor unit is fixed in the vicinity of the closed cross section formed by welding the second vehicle body panel to the substantially flat first vehicle body panel, The peeling of each vehicle body panel can be suppressed by the load.

  1 to 3 show an embodiment of the present invention. FIG. 1 is an external perspective view showing an assembled state of a rear quarter panel and a phosphorus hose, FIG. 2 is a sectional view of the rear quarter panel and the phosphorus hose, and FIG. It is explanatory drawing which shows the behavior of a rear quarter panel and a phosphorus hose at the time of a collision.

  As shown in FIG. 1, this vehicle interior fixture mounting structure is for attaching a belt anchor device 1 as an interior fixture to a rear quarter panel 2 as a first vehicle body panel. The rear quarter panel 2 is formed substantially flat, and a phosphorus hose 3 having a substantially hat-shaped cross section is welded thereto. Thereby, as shown in FIG. 2, a closed section is formed by the rear quarter panel 2 and the phosphorus hose 3.

  The phosphorus hose 3 as the second vehicle body panel extends substantially vertically and is formed in a substantially hat shape in cross section. In the present embodiment, the phosphorus hose 3 is slightly inclined rearwardly upward. The phosphorus hose 3 is welded to the rear quarter panel 2 by spot welding at the flange portions 4 at the front end and the rear end. Spot welding is performed at a plurality of points at intervals in the longitudinal direction at each flange portion 4.

  As shown in FIG. 1, the front part of the rear quarter panel 2 forms the rear part of the door opening. The belt anchor device 1 is attached in the vicinity of the closed cross section behind the connecting portion with the phosphorus hose 3. The rear quarter panel 2 is formed with a circular hole 6 in the vicinity of the nearest spot 5 below the belt anchor device 1 out of spot weld spots in the flange 4 at the rear end. As shown in FIG. 1, a circular hole 6 is provided in a closed cross-section forming portion on the obliquely lower front side of the hit point 5. Here, as shown in FIG. 1, the direction of the load applied to the belt anchor device 1 at the time of a vehicle collision is obliquely downward and forward, and the hole 6 is positioned in this load direction when viewed from the hitting point 5. That is, the hole 6 is formed corresponding to the load applied from the belt anchor device 1 at the time of a vehicle collision.

  In the vehicle interior fitting mounting structure configured as described above, a load is applied to the belt anchor device 1 from the occupant side via the seat belt when the vehicle collides. When a load is applied from the belt anchor device 1 to each of the vehicle body panels 2 and 3, first, the periphery of the hole 6 of the rear quarter panel 2 is deformed. As shown in FIG. 3, since the load is received by the rear quarter panel 2, the rear quarter panel 2 is deformed following the deformation of the phosphorus hose 3 as shown by the white arrow. . That is, the rear quarter panel 2 is deformed in the direction away from the phosphorus hose 3 as indicated by the white arrow as in the case where the hole 6 shown in FIG. In this case, an excessive load in the peeling direction does not act.

  Thereby, peeling of each vehicle body panel 2 and 3 can be suppressed with the load from the belt anchor apparatus 1 at the time of a vehicle collision, and the moving amount | distance of the belt anchor apparatus 1 can be reduced. Therefore, even when the belt anchor device 1 is fixed in the vicinity of the closed cross section formed by welding the phosphorus hose 3 to the substantially flat quarter panel 2, the amount of movement of the belt anchor device 1 of the seat belt is reduced. It is possible to improve occupant safety during a vehicle collision.

  In the present embodiment, as shown in FIG. 3, the periphery of the hole 6 in the rear quarter panel 2 is configured to be deformed toward the phosphorus hose 3 side. Accordingly, the welded portions of the panels 2 and 3 are pressed against each other, the spot welding spot portions are not peeled off, and the load of the belt anchor device 1 is resisted while the vehicle body panels 2 and 3 are connected to each other. This is extremely advantageous in terms of safety performance.

  Further, since the hole 6 is formed in the vicinity of the spot welding spot spot, peeling of the welded portion can be effectively suppressed. In the present embodiment, since the hole 6 is formed corresponding to the hit point 5 closest to the belt anchor device 1 in the rear flange portion 4 having the largest load among the hit points of spot welding, it is particularly effective. is there.

  In the above embodiment, the present invention is applied to the attachment structure of the belt anchor device 1. However, for example, the present invention can also be applied to this attachment structure using a vehicle seat device as an indoor unit. is there. In this case, the floor panel corresponds to the first vehicle body panel, and the side members, cross members, and the like correspond to the second vehicle body panel.

  In the above embodiment, the rear quarter panel 2 is welded to the phosphorus hose 3 by spot welding. However, the rear quarter panel 2 may be welded by brazing welding, laser welding, or the like. In addition, although the hole 6 is formed in a circular shape, the shape of the hole 6 may be changed to a long hole or the like according to the load direction of the belt anchor device 1 or the like. Of course, the detailed structure and the like can be changed as appropriate.
