Description

[Detailed description of the invention] (Field of industrial application) The present invention is applicable to vehicle doors, particularly vehicle doors in which a door trim is attached to the inside of the vehicle interior of a door inner panel having a working hole with a sealing screen interposed therebetween. Regarding water drainage structure.

(Prior art) Vehicle doors generally have a working hole in the inner panel of the door for attaching a window glass lifting device or a door lock device. There is a risk that a portion of the water that has entered the door may leak into the vehicle interior through the working hole.

For this reason, conventionally, a sealing screen that closes the working hole is fixed to the interior side of the door inner panel with adhesive, and a door trim is attached to the interior side of the door inner panel with the sealing screen interposed. It is done like this. In such a door structure, if the sealing screen is completely installed, water that has entered the door can be prevented as much as possible from leaking into the vehicle interior through the working hole, and the door inner panel and sealing Water flowing downward through the small gap between the screen and the screen can be stopped by an adhesive layer made of adhesive for fixing the screen.

However, it is not easy to install the sealing screen completely, and the sealing screen may peel off due to deterioration of the adhesive, etc. Therefore, water leaking along the sealing screen may leak from the lower edge of the door. Currently, there are many cases where the liquid drips from the source. In this case, the interior side of the door trim and the top of the scarf plate attached to the top of the side sill (the part corresponding to the upper joint between the side sill inner and the side sill outer) are the vehicle interior side when viewed from inside the vehicle. Since the scarf plate is set almost flush to improve its appearance, water dripping from the lower edge of the door will either travel along the top surface of the scarf plate or directly enter the passenger compartment. There is a problem of staining carpets, etc.

Therefore, in order to solve this problem, for example, as disclosed in Japanese Patent Application Laid-open No. 105823/1983, a scarf plate on the side sill is installed at the lower edge of the door trim to prevent water flowing down along the ceiling screen. A water draining structure for a vehicle door has been proposed and is known, which is characterized by providing a guide member that guides the water to the outside of the vehicle cabin from the top of the vehicle door.

(Problem to be solved by the invention) However, in the case of the above-mentioned water drain structure, the guide member is simply positioned outside the vehicle cabin beyond the top of the scarf plate to prevent water dripping from the lower edge of the door trim from entering the vehicle interior. Water dripping from the lower edge of the door trim falls and adheres to the scarf plate or side sill, that is, the lower edge of the door opening. For this reason, when a passenger opens the door to get on or off the vehicle, there is a problem in that the clothing, especially the hem of pants or skirts, gets wet.

On the other hand, a vehicle door is usually provided with a weather strip or the like on its periphery, and when the door is closed, the weather strip or the like seals the space between the door opening and the door opening, resulting in sound insulation and sealing effects. However, the reality is that these effects are not sufficient, and there is a desire to further enhance these effects.

The present invention was developed in view of these points, and its purpose is to improve the above-mentioned water drainage structure and prevent water leaking along the sealing screen from entering the passenger compartment. In addition, it prevents water dripping from the lower edge of the door onto the side sills from getting the occupants' clothes wet when getting on and off the vehicle.
Furthermore, the number of parts can be reduced while effectively increasing the sound insulation effect at the lower edge of the door.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention is a vehicle door in which a door trim is attached to the interior side of a door inner panel having a working hole with a sealing screen interposed therebetween. The configuration is as follows.

That is, the lower edge of either the door inner panel or the door trim receives the water leaking along the ceiling screen, and the water is collected from the top of the scarf plate attached to the side sill on the front and rear edges of the door. A rain rail member is attached that extends in the front-rear direction of the door leading to the outside of the vehicle interior. Further, the rain rail member is formed of an elastic member, and the lower edge thereof is provided so as to come into contact with the scarf plate when the door is closed, thereby sealing the lower edge of the door.

(Function) With the above configuration, in the present invention, when the door is closed, water leaking along the ceiling screen is received by the rain rail member attached to the door inner panel or the lower edge of the door trim, The front and rear ends of the rail member, that is, the front and rear edges of the door, are guided to the outside of the vehicle cabin from the top of the scarf plate on the side sill side. There is no chance that water will accumulate on the side sills corresponding to the center area and wet the clothes of the occupants when getting on and off the vehicle.

In addition, the lower edge of the rain rail member comes into contact with the scarf plate and seals the lower edge of the door.This allows the number of parts to be reduced due to dual use of the parts, while improving the sound insulation effect at the lower edge of the door. This means that it is possible to increase the

(Example) Hereinafter, an example of the present invention will be described based on the drawings.
