Since the door trim may need to be removed when the vehicle is repaired by an automobile dealer or the like, it is preferable that the door trim is attached to a highly rigid inner panel in consideration of the load acting at the time of removal. However, in an area where an opening for attaching the module plate is formed, for example, the area on the front side of the vehicle, it is not possible to secure a seating surface for attaching the door trim to the inner panel, and the door trim is inevitably attached to the module plate. There is a need. In that case, the resin module plate itself is not sufficiently mechanically strong and may be deformed by the load acting when removing the door trim, which causes the sealing material between the module plate and the inner panel to be deformed. It may be damaged and rainwater or water from car washing may enter the vehicle.

Therefore, an object of the present invention is to provide a vehicle side door that suppresses deformation of the module plate when the door trim is removed by complementing the mechanical strength of the module plate.

In order to achieve the above-mentioned object, the vehicle side door of the present invention is a vehicle side door that opens and closes a door opening formed on a side surface of a vehicle body, and closes an inner panel having an opening and an opening. A module plate that is attached to the interior side of the inner panel and has functional parts of the side door, and a door trim that is detachably attached to the inner panel and the module plate so as to cover the interior side of the inner panel. The reinforcement has a reinforcement fixed to the outside of the vehicle interior of the inner panel at a position adjacent to the opening, the reinforcement has an exposed area exposed from the opening to the vehicle interior side, and the module plate has a reinforcement. It is fixed in the exposed area of.

As described above, according to the present invention, by complementing the mechanical strength of the module plate, it is possible to suppress the deformation of the module plate when the door trim is removed.

FIG. 2 is a side view of the inner panel constituting the vehicle side door of the present embodiment as viewed from the vehicle interior side. FIG. 3 is a cross-sectional view taken along the line AA of FIG. In addition, in FIG. 1, in order to make the figure easier to see, the illustration of the door trim constituting the vehicle side door is omitted.

The vehicle side door (hereinafter, also simply referred to as “side door”) 1 of the present embodiment is a side door on the right rear side of the automobile, and is a sliding side door that slides in the front-rear direction of the vehicle to open and close the door opening. be. The side door 1 has a door main body 2 and a resin door trim 3 which is an interior material provided on the vehicle interior side of the door main body 2.

The door body 2 has an outer panel 21 and an inner panel 22 joined to the vehicle interior side of the outer panel 21. The outer panel 21 may be made of metal, but is preferably made of resin, and particularly preferably made of polypropylene compound. The inner panel 22 may be made of metal, but is preferably made of resin, and particularly preferably made of sheet molding compound (SMC), which is a sheet obtained by impregnating glass fiber or carbon fiber with unsaturated polyester resin. Or, it is made of a composite material of glass fiber or carbon fiber and polypropylene resin. A substantially rectangular wind opening 23 is formed in the upper part of the door body 2, and a service hole (opening) 24 is formed below the wind opening 23 of the inner panel 22.

At the end of the door body 2 on the front side of the vehicle, a clevis (shown) that engages with a striker provided on the vehicle body to prevent the side door 1 from falling off from the vehicle body when an impact is received from the outside due to an accident or the like. ) Is provided. In order to reinforce this clevis, a metal clevis reinforcement 4 is fixed to the outside of the passenger compartment of the inner panel 22. The clevis reinforcement 4 is arranged on the vehicle front side of the service hole 24, and is formed so that the end portion 4a on the vehicle rear side is exposed from the service hole 24 to the vehicle interior side.

A wind panel (not shown) for opening and closing the wind opening 23 is provided between the outer panel 21 and the inner panel 22, and the side door 1 has various types of wind regulators for raising and lowering the wind panel. Functional parts are incorporated. That is, the side door 1 has a module plate 5 in which such various functional parts are modularized. The module plate 5 is attached to the vehicle interior side of the inner panel 22 so as to close the service hole 24 by a fastening member 11 such as a bolt or a nut. Further on the vehicle interior side of the module plate 5, a bracket 6 for supporting an inside handle (not shown) is attached by a fastening member 11. Further, between the inner panel 22 and the module plate 5, an adhesive or a foam is used to prevent rainwater that has entered the inside of the door body 2 through the wind panel and water during car washing from leaking into the vehicle. A sealing material 12 is provided.

The door trim 3 is detachably attached to the door body 2 by a resin clip 13 so as to cover the vehicle interior side of the inner panel 22. The inner panel 22 is formed with a plurality of mounting holes 14 into which the clips 13 are inserted, but since the service holes 24 are formed in the area on the front side of the vehicle, a seat for mounting the door trim 3 is formed. The surface cannot be secured and the mounting hole 14 cannot be formed. Therefore, in the region of the inner panel 22 on the front side of the vehicle, a mounting hole 14 is formed in the module plate 5. Therefore, the door trim 3 is attached not only to the inner panel 22 but also to the module plate 5.

However, since the resin module plate 5 itself does not have sufficient mechanical strength, it may be deformed by the load acting when the door trim 3 is removed. As a result, the sealing material 12 provided between the inner panel 22 and the module plate 5 is damaged, and rainwater or water during car washing may leak into the vehicle from the damaged portion.

Therefore, in the present embodiment, as described above, the end portion 4a on the rear side of the vehicle of the clevis reinforcement 4 is exposed from the service hole 24 to the vehicle interior side, and the module plate 5 is exposed together with the bracket 6 in the exposed region 4a. It is fixed. In addition, a mounting hole (mounting portion) 14 to which the door trim 3 is mounted is provided at a position of the module plate 5 adjacent to the exposed region 4a of the clevis reinforcement 4. As a result, even if a load acts on the module plate 5 when the door trim 3 is removed by an automobile dealer or the like, the mechanical strength of the module plate 5 can be supplemented and the deformation of the module plate 5 can be suppressed. As a result, it is possible to suppress damage to the sealing material 12 and reduce the possibility that rainwater or water during car washing will infiltrate into the vehicle.

In the above-described embodiment, the module plate 5 is fixed to the clevis reinforcement 4 arranged on the front side of the vehicle of the inner panel 22, but the module plate 5 is used to supplement the mechanical strength of the module plate 5. The fixed reinforcement is not limited to the clevis reinforcement 4. That is, when the seat surface for mounting the door trim 3 cannot be secured in the area other than the area on the front side of the vehicle of the inner panel 22, if another reinforcement is provided adjacent to the area, the seat surface is not secured. The end of the reinforcement may be exposed from the service hole 24 and the module plate 5 may be fixed therein.
