[0003]

[Problems to be solved by the device]

 By the way, in a side door of an automobile, the strength of the door itself is secured by attaching reinforcing members to a plurality of locations inside the side door.

However, the above-mentioned conventional side door has a configuration in which a plurality of types of reinforcing members are individually joined to a plurality of locations inside thereof, and the joining work and management of a plurality of types of reinforcing members are performed. It was troublesome. Further, in the above-mentioned conventional side door, since the inner panel and the outer panel are directly joined to each other, for example, the elevating mechanism of the door glass, the guard bar, etc. are unitized with the reinforcing member, and the unit is sandwiched between the inner panel and the inner panel. When joining the outer panel, the joint between the reinforcing member, the inner panel and the outer panel in the unit becomes complicated and it becomes difficult to secure sufficient strength of the door itself. However, when the inner panel and the outer panel are made of a low-strength aluminum alloy in order to reduce the weight of the door itself, there is a problem that it becomes more difficult to secure the strength of the door itself.

An object of the present invention is to provide a door in which the inner panel, the outer panel and the reinforcing member can be easily joined together and the strength of the door itself can be sufficiently ensured. is there.

[0006]

[Means for Solving the Problems]

 The door of the present invention is a door in which a plurality of edge portions of an inner panel and an outer panel are joined to each other, and a plurality of edge portions of the inner panel have a plurality of edge portions facing the plurality of edge portions. A reinforcing member is joined and a plurality of edge portions of the outer panel are joined to the reinforcing member.

[0007]

[Action]

 The door of the present invention joins the edge portions of the inner panel and the outer panel through the reinforcing member having a plurality of edge portions, thereby simplifying the configuration of those joining portions and ensuring sufficient joining strength. At the same time, the lack of rigidity due to the use of aluminum for the inner and outer panels can be eliminated. Further, as compared with the conventional case where a plurality of reinforcing members formed separately for each of a plurality of edge portions are handled, the joining work of the reinforcing members and the management thereof can be facilitated.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. This embodiment is an application example as a side door 1 of an automobile.

In FIG. 1, reference numeral 10 denotes an outer panel having a substantially quadrangular plane, which is made of an aluminum alloy in this example. A rain force member (reinforcing member) 20 is joined to the inner surface of the outer panel 10. The reinforcement member 20 is composed of an outer peripheral portion 21 having a substantially rectangular frame shape in a plane having a size substantially equal to that of the outer panel 10, and a rib portion 22 having a substantially plane shape in a plane inside thereof. The upper, lower, front and rear four edge portions 21A, 21B, 21C, 21D of the outer peripheral portion 21 and the upper, lower, front and rear four edge portions 10A, 10B, 10C, 10D of the outer panel 10 are joined to each other. The joining structure thereof is arbitrary. For example, the upper edge portions 10A and 21A are spot-welded in a form of simple surface contact as shown in FIG. 2, and the other three edge portions 10B are connected. , 21B, 10C and 21C, 10D and 21D are spot-welded in such a manner that the latter side is held by the bending of the former side of each set, as shown in FIGS. Further, if necessary, the outer panel 10 and the appropriate portion of the reinforcement member 20 are joined by means such as rivets. A damping sheet 30 for vibration damping is attached to the inner surface of the outer panel 10 by means such as adhesion.

In FIG. 2, reference numeral 40 denotes an inner panel, which includes upper and lower side portions 41A and 41B extending in the horizontal direction and front and rear side portions 41C and 41D extending in the vertical direction (FIG. 3 and FIG. 4)), the outer panel 10 and the outer panel 10 have a substantially rectangular frame shape. A swelling portion of a door trim, which will be described later, is fitted into a substantially square hole 42 (see FIG. 2) in the center of the inner panel, and four side portions 41A, 41B, 41C, 41D. Each of them is bent and formed into an appropriate cross-sectional shape or has a hole or the like formed therein.

Further, in the case of this example, the upper side force member 51 (see FIG. 2) extending in the longitudinal direction is joined to the upper side portion 41A of the inner panel 40 by spot welding or the like, Further, a front reinforcement member 52 extending in the longitudinal direction (front and back direction of the paper surface in FIG. 3) is joined to the side portion 41C on the front side of the vehicle body by spot welding or the like. Further, as shown in FIG. 3, a hinge 53 for rotatably connecting the door 1 to a pillar 61 of the vehicle body is attached to the front reinforcement member 52. As shown in FIG. 4, a door lock mechanism 54 engageable with a striker 62 on the vehicle body side is attached to a side portion 41D on the vehicle body rear side of the inner panel 40. Further, the reinforcement members 51, 52 are provided with an elevating mechanism (not shown) for elevating the door glass 55 indicated by the chain double-dashed line in FIG.

The edge portions 43B, 43C and 43D of the lower side, the vehicle body front side and the vehicle body rear side sides 41B, 41C and 41D of the inner panel 40 are shown in FIGS. 2, 3 and 4, respectively. Thus, the screws 70 are joined to the lower side of the reinforcement member 20, the vehicle body front side and the vehicle body rear side edge portions 21B, 21C and 21D, respectively. Further, the edge portion 43A of the upper side portion 41A of the inner panel 40 and the upper edge portion 21A of the reinforcement member 20 are separated from each other by an amount that allows the door glass 55 to move up and down, and are separated from each other. Weather strips S, S are attached. Further, the inner panel 40 is provided with a door trim 54 having a bulging portion 54A and a pocket portion 54B fitted in the hole 42.

Therefore, in the side door 1 having such a configuration, the outer panel 10 and the inner panel 40 are joined to each other via the reinforcement member 20 which is joined to the former outer panel 10 side in advance. In other words, the joint between the outer panel 10 and the reinforcement member 20 and the joint between the reinforcement member 20 and the inner panel 40 are displaced on the reinforcement member 20. Therefore, the structure of the joint portion of the outer panel 10, the inner panel 40 and the rain force member 20 is simplified, and sufficient joint strength is secured. Moreover, since the reinforcement member 20 integrally has a plurality of edge portions 21A, 21B, 21C, 21D that individually perform the reinforcing function, a plurality of reinforcement members formed separately for each edge portion. Compared with the case of handling, joining work of reinforcement members and its management become easier.

Further, the reinforcement member 20 may be made into a unit together with an elevating mechanism of the door glass 55, a guard bar, etc. In that case, the reinforcement member in the unit may be sandwiched so as to sandwich the unit. By joining the outer panel 10 and the inner panel 40 to 20, the side door 1 can be easily configured. Further, since the inner panel 40 is joined to the reinforcement member 20 by the screw 70, the inner panel 40 can be attached and detached. Further, since the joint portion between the reinforcement member 20 and the inner panel 40 is located closer to the center of the door 1 than the joint portion between the outer panel 10 and the reinforcement member 20, the reinforcement member 20 is exposed to the outside. It never happens.

[0015]

[Effect of device]

 As described above, the door of the present invention has a structure in which the edge portions of the inner panel and the outer panel are joined to each other via the reinforcing member having a plurality of edge portions, so that the configuration of the joint portions is simplified. As a result, sufficient joint strength can be secured, and the lack of rigidity that accompanies the use of aluminum for the inner panel and outer panel can be eliminated. Moreover, as compared with the conventional case of handling a plurality of reinforcing members formed separately for each of a plurality of edge portions, the work of joining the reinforcing members and the management thereof are facilitated.
