Description

  The present invention relates to a method for attaching a post-installation exterior component in the case where an existing exterior component covering a lower portion of a door body is replaced with a post-installation exterior component.

As a car door, a door body made of steel plate and a composite attached to cover the lower part of the door body to protect the lower part of the door body from stepping stones and mud splashed while driving Some are composed of resin exterior parts.
As this exterior component, there is a covering member described in JP-A-2003-200804 (hereinafter referred to as Patent Document 1).
As shown in FIG. 4 in Patent Document 1, the covering member 10 extends below the lower edge 601 of the door outer plate 61 out of the door outer plate 61 and the door inner plate 62 constituting the door body 60. The main covering member 20 covering the lower end of the lever and the main covering member 20 is coupled to the main covering member 20 and closes the gap between the lower edge 24 of the main covering member 20 and the lower edge 601 of the door outer plate 61. And the sub-cover member 30 that holds the door on the door outer plate 61.

  However, the above-described conventional covering member 10 has a problem that the assemblability is poor because two large parts of the main covering member 20 and the sub covering member 30 that are substantially the same as the length of the door are assembled separately.

Therefore, as shown in FIG. 7, the applicant of the present application arranges the exterior part 10 c so as to cover the outdoor surface of the outer plate 61 below the door body 60 and is fixed to the outer plate 61, and the door body. 60. The inner portion 30c is disposed so as to cover the inner surface of the lower inner plate 62 and is fixed to the inner plate 62. The outer portion 20c and the inner portion 30c are integrally formed via the thin hinge portion 11c. We thought that the above problem could be solved by adopting a structure.
JP 2003-200804 A

By the way, such an exterior part is an existing exterior part (hereinafter referred to as an “existing exterior part”) that is normally attached in the vehicle manufacturing process in accordance with the destination of the vehicle (cold area, etc.) and the design demand. Instead, a retrofit exterior part may be attached.
However, as described above, when the existing exterior part has a structure in which the outer part and the inner part are integrally formed, the entire existing exterior part is discarded when the retrofitting exterior part is attached, and the amount of waste is reduced. Will increase. Further, the retrofitting exterior part is expensive because it is necessary to configure the exterior part and the inner part in the same manner as the existing exterior part.

  Therefore, in order to solve such a problem, the present invention is easy to assemble an existing exterior part, can reduce the amount of waste when attaching a rear exterior part instead of the existing exterior part, It is an object of the present invention to provide a retrofit exterior part mounting method that can be made inexpensive and that can reduce the burden of replacing existing exterior parts and retrofit exterior parts.

  According to a first aspect of the present invention, there is provided a retrofitting exterior part mounting method comprising a door body and an existing exterior part attached to the door body, wherein the existing exterior part covers an outdoor surface of the door body.

Therefore, the existing exterior component has a structure in which the outer side portion and the inner side portion are integrally molded, and therefore, the assembling property is good. In addition, since the retrofitting exterior part is attached using the inner part of the existing exterior part, waste can be reduced by the amount of the inner part, and the retrofitting exterior part can be made small and inexpensive.
Moreover, since the outer part and the inner part of the existing exterior part are cut by the thin hinge part, it can be easily cut, so that the burden of replacing the existing exterior part and the retrofitted exterior part can be reduced.

Moreover, the retrofit exterior component attachment method according to claim 2 according to the present invention is the retrofit exterior component attachment method according to claim 1, wherein the retrofit exterior component is an outer portion of the existing exterior component. And a connecting part connected to the main body part via a thin hinge part, and fixing the connecting part to the inner part of the existing exterior part, It couple | bonds with the said inner part, It is characterized by the above-mentioned.
Therefore, since it can connect in the state which expand | deployed the retrofit exterior component and the inner part of the existing exterior component, and can be assembled | attached to a door main body, the workability | operativity of connection and assembly is good.

According to the present invention, the existing exterior part has a structure in which the outer part and the inner part are integrally formed, so that it can be easily assembled. Further, since the retrofitting exterior part is attached using the inner part of the existing exterior part, the waste of the inner part can be reduced, and the retrofitting exterior part can be made small and inexpensive.
Moreover, since the outer part and the inner part of the existing exterior part are cut by the thin-walled hinge part, the outer part and the inner part can be easily cut. Therefore, the burden of replacing the existing exterior part and the retrofitted exterior part can be reduced.
