Description

The present invention relates to a vehicle door lighting structure.

2. Description of the Related Art Conventionally, there is known a vehicle door lighting structure in which a lighting device is arranged on a door trim of a hinge door (see, for example, Patent Document 1). Specifically, this door lighting structure has a light source on the bottom surface of a door pocket (the surface facing the floor surface of the vehicle compartment) that protrudes from the inner wall surface of the door trim toward the vehicle compartment. According to such a door lighting structure, when the hinged door is opened, the lighting device is turned on to illuminate the feet of the occupant when getting in and out of the vehicle.

JP 2007-314073 A

By the way, the door lighting structure is not limited to the conventional door lighting structure provided on the hinge door (see, for example, Patent Document 1), and it is desired to apply it to the sliding door as well.
However, when a conventional door lighting structure is applied to a sliding door, this door lighting structure cannot illuminate the feet of passengers when getting in and out of the vehicle because the open sliding door overlaps the outside of the vehicle body.
In addition, in this door lighting structure, the lighting device, which faces the road surface when the door is opened, is easily soiled by dirt, mud, and the like from the road surface.

It is an object of the present invention to provide a vehicle door lighting structure capable of effectively illuminating the feet of passengers when getting in and out of a vehicle when a slide door is opened, and making it more difficult for dirt to adhere to the lighting device than before. be.

The vehicle door lighting structure of the present invention, which solves the above problems, comprises a sliding door that opens and closes a door opening by sliding in the longitudinal direction of the vehicle; A recessed space formed to be recessed and a lighting device provided on an upper surface of the recessed space are provided, and the recessed space extends from the door end surface on the closing side of the sliding door toward the opening side of the sliding door. The lighting device is provided across the upper surface and the door end surface at a corner formed by the upper surface of the recessed space and the door end surface on the closing side of the sliding door, The end of the sliding door on the closed side where the recessed space is formed consists of a side wall surface facing the interior of the vehicle at a portion corresponding to the recessed space, and a side wall facing the interior of the vehicle from the side wall at the closing side of the slide door. and a second protruding wall protruding from the side wall surface toward the interior of the vehicle on the opening side of the sliding door, and the second protruding wall The protruding length of the first protruding wall is shorter than the protruding length of the protruding wall .

According to the present invention, there is provided a vehicle door lighting structure capable of effectively illuminating the feet of passengers when getting in and out of a vehicle when a slide door is opened, and preventing dirt from adhering to the lighting device more than before. be able to.

It is the side view which looked at the slide door provided with the door lighting structure which concerns on embodiment of this invention from the vehicle interior inside. FIG. 2 is a partially enlarged perspective view of the sliding door viewed from the direction of arrow II shown in FIG. 1; FIG. 4 is a partially enlarged perspective view of the closing-side lower end portion of the sliding door as seen from the inside of the vehicle compartment; FIG. 2 is a sectional view along IV-IV in FIG. 1; FIG. 4 is a partially enlarged perspective view showing a top surface of a recessed space formed in the slide door as viewed from below the inside of the vehicle compartment; FIG. 4 is a partially enlarged perspective view of the fixed portion of the lighting device as seen from the outside of the vehicle with the door body (outer panel and inner panel) of the sliding door removed.

Next, a form (embodiment) for carrying out the vehicle door lighting structure of the present invention will be described in detail with appropriate reference to the drawings.
In the following, the door lighting structure of the present embodiment will be described by taking as an example the one provided on the right sliding door of the pair of left and right sliding doors provided so as to correspond to the rear seats of the vehicle. However, the door lighting structure of the present invention is not limited to this, and can be applied to various sliding doors. It should be noted that the front, rear, up, down, left, and right directions in the following description are based on the directions indicated by the arrows in each drawing that correspond to the front, rear, up, down, left, and right directions of the vehicle.

FIG. 1 is a side view of a sliding door 4 that constitutes the vehicle door lighting structure 1 as viewed from the inside of the vehicle compartment.
As shown in FIG. 1, the sliding door 4 in this embodiment opens and closes the door opening by sliding in the longitudinal direction of the vehicle. Incidentally, although illustration is omitted, the door opening is formed in a substantially rectangular shape surrounded by a center pillar, a rear pillar, a roof rail, and side sills. The sliding door 4 is supported by the roof rail and the side sills so as to slide in the longitudinal direction of the vehicle body.

Further, as shown in FIG. 1, when the slide door 4 is opened, the door opening 2 appears on the front side of the vehicle, allowing passengers to get in and out of the vehicle. With respect to the door opening 2, the front part of the slide door 4 is on the closing side of the sliding door 4, and the rear part of the sliding door 4 is on the opening side of the sliding door 4.例文帳に追加

Such a sliding door 4 is composed of an outer panel (not shown) forming the outer surface of the vehicle and an inner panel (not shown) provided inside the vehicle so as to form a hollow space between the outer panel and the outer panel. and a door trim 5 attached to the interior side of the door body 6 (the front side of the paper surface of FIG. 1) and serving as an interior material.

As shown in FIG. 1, the door trim 5 in this embodiment is assumed to consist of a resin-molded panel that is vertically divided into a plurality of parts (four parts in this embodiment). It can also be a single panel.
