Japanese Patent Application Publication No. 2019-026262

By the way, when a courtesy lamp is attached to a door trim, the interior of the vehicle is equipped with a light-transmissive cover that protects the light source, but the exterior of the vehicle (i.e., the back side of the door trim) is open for heat dissipation. There is something that is. In that case, debris and dust generated from the shock absorbing member during vehicle door assembly may adhere to the light source of the courtesy lamp or accumulate on the outside of the vehicle on the light-transmitting cover, impairing the performance of the courtesy lamp. There was a risk that it would be damaged or the appearance would deteriorate. According to the inventors' study, providing a cover on the outside of the courtesy lamp not only adds a cover member, but also serves as a cover to dissipate heat from the light source, its peripheral elements, power supply unit, etc. Since it is necessary to also provide a heat dissipation mechanism, the cost increases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door trim for a vehicle that can prevent the performance and appearance of a courtesy lamp from deteriorating.

As a means for solving the above problems, the vehicle door trim disclosed herein includes a trim board attached to the inside of the vehicle interior of the door panel of the vehicle door, and a trim board attached to the outside side of the vehicle interior of the trim board, and The door is equipped with a shock absorbing member that absorbs shock applied to the door. The trim board has an accommodation hole formed below the shock absorbing member for removably accommodating a courtesy lamp unit that illuminates the lower side of the vehicle door and inside the vehicle interior, and further below the shock absorbing member. A projecting wall portion is provided below the housing hole and above the accommodation hole, the projecting wall portion having a plate shape and rising from the outside surface of the vehicle room to the outside of the vehicle room.

In the above configuration, when the courtesy lamp unit is installed in the accommodation hole, the protruding wall portion is configured to cover the top of the courtesy lamp unit. This prevents debris and dust falling from the shock absorbing member from entering the courtesy lamp unit, thereby preventing deterioration in performance and appearance of the courtesy lamp. Further, the protruding wall portion is arranged in a direction from the inside of the vehicle interior to the outside of the vehicle interior. Therefore, the protruding wall portion can also receive the impact at the time of a side collision. This makes it possible to reduce the volume of the impact-absorbing member that is required to be included in the vehicle door trim in order to alleviate the same magnitude of impact, compared to the case where the protruding wall portion is not provided.

In a preferred aspect of the present invention, the trim board includes a first board to which the shock absorbing member is attached, and a second board connected below the first board and in which the accommodation hole is formed. The protruding wall portion is formed by partially bending and extending a lower end of the first board toward the outside of the vehicle interior. In such a configuration, since the protruding wall portion is integrally formed with the first board, the number of parts of the trim board can be reduced.

In a preferred aspect of the present invention, the protruding wall portion includes a plate-shaped main body portion and an eaves portion that is continuous with the main body portion outside the vehicle interior and extends downward. According to such a configuration, since the protruding end of the protruding wall is curved in the opposite direction to the side of the shock absorbing member, when the shock absorbing member is attached to the trim board, the shock absorbing member is not attached to the end of the protruding wall. You can avoid hurtful situations.

In a preferred aspect of the present invention, the protruding wall further includes a rib that stands up from the main body and the eaves. According to such a configuration, the effect of mitigating the impact caused by the protruding wall portion in the event of a side collision can be further enhanced. Furthermore, by adjusting the number, size (dimensions), etc. of ribs provided on the protruding wall, it is possible to control the degree of impact mitigation effect of the protruding wall in the event of a side collision.

In a preferred aspect of the present invention, the trim board includes a sloped part below the shock absorbing member that slopes toward the outside of the vehicle cabin as it goes downward, and the accommodation hole is formed in the sloped part. . According to such a configuration, since the accommodation hole is provided in the inclined part, the courtesy lamp unit illuminates the lower part of the inside of the vehicle interior of the vehicle door (i.e., the feet of the passenger getting on and off the vehicle when the vehicle door is opened). Can be illuminated effectively. On the other hand, the rear surface of the courtesy lamp unit is directed upward toward the interior of the vehicle. Such a configuration is preferable because the functions of the courtesy lamp unit are effectively exhibited and the effects of the present invention are significantly exhibited.

According to the present invention, it is possible to provide a door trim for a vehicle that can prevent deterioration in the performance and appearance of a courtesy lamp.
