Description

[Detailed explanation of the invention] (Industrial application field) Vehicles are equipped with various accessory cases. For example, a glove box, a center console box, etc. The lids of these accessory cases are called lids, and some lids have a urethane foam layer on the surface to give them a soft feel. The present invention relates to an improvement in the structure of this vehicle lid.

(Prior art) The vehicle lid to which the present invention is applied is
As shown in the figure, the urethane raw material is injected between the skin material 3 and the lid outer core 1 through the injection hole 2 provided in the lid outer core 1, and is foamed to form the skin material 3, the urethane 4, and the lid outer core 1. The lid inner 6 is assembled to the lid outer 5 which is integrated with the door outer core 1.
The structure of is generally known.

(Problem to be solved by the invention) The layer of urethane 4 provided on the lid outer 5 of the lid 7 is placed in a closed space formed by the skin material 3 and the lid outer core 1. It is formed by injecting a urethane raw material through an injection hole 2 provided in the . However, if the diameter of the injection hole 2 of the lid outer core 1 is smaller than the width and thickness of the lid 7, the urethane raw material cannot be poured in quickly, and the urethane raw material may foam during the injection. At the beginning, there is a problem of air pockets and lack of thickness in the urethane 4 layer.

On the other hand, if the diameter of the injection hole 2 is large, the urethane raw material can be easily injected, and the above-mentioned problems are less likely to occur. However, the lid outer core 1 functions to support the urethane 2, and since the diameter of the injection hole 2 is large, the area of the urethane 2 exposed from the injection hole 2 becomes large. As a result, as shown in FIG. 4, the injection hole 2 on the surface of the lid 7 is
When a load 8 is applied to a portion corresponding to , a larger deflection occurs than in other portions. This impairs the feel of the lid surface and, if worse, may cause plastic deformation, which greatly reduces the performance of the lid.

Conventionally, designers have empirically determined the optimum injection hole diameter that can satisfy both of the above problems. However, that doesn't necessarily mean it will work.

In view of this, the present invention aims to provide a structure for a vehicle lid that fundamentally solves the above-mentioned problems.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention is provided in the lid outer core in a closed space formed by the skin material and the lid outer core. The lid inner is assembled from the lid outer core side to the lid outer in which the skin material, lid outer core, and urethane are integrated by foaming the urethane raw material injected through the injection hole in the closed space. Targeting the structure of a vehicle lid, the lid inner is provided at a portion facing the injection hole of the lid outer core so as to protrude toward the lid outer core side, and is configured to support the urethane exposed from the injection hole. The structure includes ribs that are in contact with the urethane.

(Function) With the above configuration, the urethane exposed from the injection hole of the lid outer core is supported by the ribs provided on the lid inner, so that poor feel and deflection of the lid surface are prevented. Furthermore, it becomes possible to increase the diameter of the injection hole in the lid outer core, and the moldability of the lid outer core can be improved.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 3 is a perspective view of the console box lid 7. This cross section taken along the line A-A is shown in FIG.

The console box lid 7 (hereinafter referred to as lid) is composed of a lid outer 5 consisting of a skin material 3, urethane 4, and a lid outer core 1, and a lid inner 6.

The skin material 3 is made of soft resin, and the lid surface 1
The appearance of 0 is formed.

The lid outer core 1 is made of resin and is formed in a shape corresponding to the skin material 3, and allows the urethane 4 to be coated and maintains the overall shape of the lid outer 5.

An injection hole 2 is provided in the center of the lid outer core 1 for injecting the urethane raw material forming the layer of the urethane 4, and a surface corresponding to the lid inner 6 is provided for assembling the lid inner. A plurality of bosses 11 and reinforcing ribs 12 are provided.

The urethane 4 is formed by injecting a urethane raw material into the closed space formed by the skin material 3 and the lid outer core 1 through the injection hole 2 and foaming the urethane raw material.

These skin materials 3 and lid outer core 1 are
The skin material 3, the lid outer core 1, and the urethane 4 are bonded to the urethane 4, and together constitute the lid outer 5.

The lid inner 6 is made of resin, and the appearance of the lid back side 13 is shaped. In addition, as shown in FIG. 2, the lid inner 6 has a plurality of ribs 9 protruding vertically and horizontally toward the injection hole 2 at a portion of the lid outer core 1 facing the injection hole 2 on the surface facing the lid outer 5. ing.

The lid inner 6 and lid outer 5 are joined by a screw 14. In this state, the tip of the rib 9 of the lid inner 6 is made of urethane 4 which is exposed from the injection hole 2 of the lid outer core 1.
The urethane 4 is supported by being in contact with the urethane 4. Also,
The outer peripheral edge 15 of the lid inner 6 and the outer peripheral edge 16 of the lid outer core 1 are connected to the skin material 3 and the urethane 4.
The lid 7 is integrally constructed by sandwiching the terminal portion 17 of the lid 7 to prevent the terminal portion 17 from turning over.

In addition, the rib 9 provided on the lid inner 6
is the shape as long as it can sufficiently support the urethane 4 exposed from the injection hole 2,
The number is not limited. Further, the material of each member constituting the lid 7 is not limited to this.

(Effects of the invention) As described above, according to the invention, the urethane is provided in the lid inner in a portion facing the injection hole of the lid outer core so as to protrude toward the lid inner and support the urethane exposed from the injection hole. Since the rib is in contact with the lid, even if the diameter of the injection hole is set large, the urethane will not come out from the injection hole to the lid inner side, which prevents the lid surface from becoming unfeeling or warping.

Furthermore, by setting the diameter of the injection hole to be large, the moldability of the lid outer core is improved.

Therefore, according to the present invention, it is possible to provide a vehicle lid structure that is free from defects on the lid surface caused by the urethane injection hole and has excellent moldability.
