Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a side door structure for a vehicle in which a side opening for occupant getting on and off of a vehicle is openably and closably closed, and a method for assembling the same.
[0002]
[Prior art]
Conventionally, there is the following structure as a side door structure of a vehicle. That is, a continuous door opening without a partition is provided on the side of the vehicle body, and this door opening is covered with a front door and a rear door so that it can be opened and closed. The front door is pivotally connected to the vehicle body via a front door hinge, and the rear door is The rear part is pivotally attached to the vehicle body via the rear door hinge, and the side door consisting of these front door and rear door is configured as a so-called double door structure, and the rear end of the front door is overlapped with the outside of the front end of the rear door, In addition, a reinforcing member extending vertically is provided inside the front end of the rear door (for example, see Patent Document 1).

[0004]
[Problems to be solved by the invention]
Generally, an opening for attaching a door module unit is formed in the door inner panel of the above-described front door, and the door module unit is attached to this opening.
[0005]
The above-described door module unit is a module in which door functional components such as a speaker, a wire harness, a window regulator, and a door latch unit are integrally formed with a module panel (which is the same as a door module and a module plate).
[0006]
Conventionally, door functional components such as a window regulator and a door latch unit have been integrated into a module panel in advance, which has the following problems.
[0007]
That is, since the door latch unit is connected to the inner handle via a wire cable, and the inner handle is located at a position relatively higher than the door latch position of the door, when the door latch unit is integrated with the module panel in advance, The assemblability deteriorates.
[0008]
In addition, the above-described door latch unit needs to be connected to the outer handle via a door key cylinder rod or the like, and when the door latch unit is first assembled to the module panel, an operator puts his hand in the door and puts his hand in the door. The work of connecting the door latch unit and the key cylinder with the door key cylinder rod is required, and this workability deteriorates.
[0009]
In order to solve such a problem, for example, it is conceivable that the above-described door latch unit is previously attached to the door side and then the door module unit is attached. In this case, the door latch and the door latch Due to the structure of the door latch unit comprising an actuator for driving the door module, when the actuator is cantilevered and the door module unit is disposed in the opening for mounting the door module, the actuator is moved between the door inner panel and the door outer panel. In addition to escaping into the space, the actuator also escapes into the space when transmitting a drive power supply and a drive signal to the connector of the above-described actuator, and inserting the connector on the tip side of the wire harness that supplies the same. There was a problem that smooth assemblability was hindered.
[0010]
According to the present invention, by providing a locking portion for temporarily storing another door functional component coupled to the door module unit in the door module mounting opening, the other door functional component and the main body of the door module unit are simultaneously assembled. It is an object of the present invention to provide a vehicle side door structure that can secure door assemblability in a door form that is difficult to attach.
[0011]
The present invention also provides a method of temporarily depositing another door functional component in a door inner panel, connecting a signal line to the next component, and then fixing the door module unit to the door inner panel, thereby providing another door functional component. It is an object of the present invention to provide a method for assembling a side door of a vehicle, which can ensure the assemblability of a door in a door form in which it is difficult to assemble the door module unit and a main body of the door module unit at the same time.
[0012]
