Description

[Detailed Description of the Invention] This invention relates to the structure of a rear parcel for an automobile. More specifically, the present invention relates to a reinforcement structure for an automobile rear parcel.

Rear parcels installed in the rear seats of automobiles are generally formed into a shelf shape using boards made by kneading fibers, wood powder, etc. into thermoplastic synthetic resin and molding them.Items are placed on these boards. In order to withstand the load caused by this and the thermal distortion of the board due to temperature rise due to solar heat, etc., a reinforcement material made of a metal material such as a steel plate is usually placed at the bottom of the board. It is.

FIG. 1 is a sectional view showing an example of a conventional automobile rear parcel structure. In the figure, reference numeral 1a denotes a reinforcement material made of a material having a required rigidity, such as a steel plate, and is placed between the lower surface of the upper board 2 and the lower board 3. The upper board 2 and the lower board 3 are made by kneading thermoplastic synthetic resin with fibers, wood flour, etc., and molding them.The lower board 3 is heated and then the upper board 2 and the rainforth material 1 are formed.
It is press-bonded to a and integrally molded into a sandwich shape. The upper surface of the upper board 2 has a cross,
A skin material 4 such as cloth is mounted. In some cases, the lower board 3 is omitted and only the upper board 2 is glued to the reinforcement material 1a to form a rear parcel shelf, or the lower board 3 covers the entire underside of the upper board 2. In some cases, it is applied only to the portion that covers the reinforcement material 1a.

FIG. 2 is a perspective view illustrating the shape of reinforcement material used in the conventional rear parcel structure as described above. 1a in FIG. 1A is the one shown in FIG. 1, which is a combination of a member formed into a groove shape (the valley shape of a deck plate) and a flat member. 1b of b is one in which a U-shaped member is further incorporated into the groove-shaped member of 1a to increase the rigidity. In addition, 1c of c uses a square tubular member.

Conventional rear parcel materials such as those mentioned above must be made larger in cross-section and thicker in order to increase their rigidity and reinforcement strength, but this increases the weight of the rear parcel and increases its strength. Since the shape is large, the product lacks marketability, and especially in the case of combined parts such as those shown in 1a and 1b, there is a drawback that the cost increases significantly.

The present invention was made with the aim of solving the above-mentioned conventional drawbacks and providing a rear parcel for automobiles that is lightweight and compact and has a reinforcement material that can provide the required strength. The gist of the invention is that a reinforcement material formed in the shape of a sheet is placed at the bottom of the board perpendicularly to the width direction of the band-shaped plate. Hereinafter, the configuration of the present invention will be explained based on the embodiments shown in the drawings.

FIG. 3 is a perspective view showing one embodiment of the reinforcement material used in the rear parcel for an automobile according to the present invention, and FIG. 4 is a plan view thereof. This reinforcement material 1 is formed by forming a band-shaped plate such as a steel plate into a corrugated shape as shown in the figure. FIG. 5 is a sectional view showing a rear parcel structure using this reinforcement material 1. The reinforcement material 1 is arranged on the lower surface of the upper board 2 with the width d direction of the strip-shaped plate material being perpendicular. Upper board 2, lower board 3
The structure of the rear parcel shelf according to the above-mentioned first
The situation is similar to the conventional example shown in the figure, but in this case, the upper board 2 is supported by the width of the wave height h of the corrugated strip material, and the section modulus of the strip material in the width (height) direction is effectively utilized. reinforcement is carried out. It goes without saying that it is preferable to set the wave height h as large as possible in order to improve the supportability and prevent the reinforcement material 1 from falling during sandwich forming.

FIG. 6 is a perspective view showing another embodiment of the reinforcement material used in the present invention, and FIG. 7 is a plan view thereof. The reinforcement material 1' of this example is provided with a horizontal flange 5 on its upper edge. Although this flange 5 may be fixed to the main body of the reinforcement material 1' by welding or the like, it is preferably formed integrally from a plate material. FIG. 8 is a sectional view showing a rear parcel structure using a reinforcement material 1' having such a flange 5. The provision of this flange 5 improves the support of the upper board 2, and also facilitates setting during board molding, improving work efficiency. In addition, FIG. 9 is a cross-sectional view showing another example of the rear parcel structure using this reinforcement material 1'. In this example, the lower board 3' does not cover the entire surface of the upper board 2, Only the periphery of the reinforcement material 1' is covered.

The automobile rear parcel of the present invention is constructed as described above, and a reinforcement material formed by forming a band-like plate into a corrugated shape is arranged at the bottom of the board with the width direction of the band-like plate perpendicular to the board to support the load of the board. Since it is reinforced, it is possible to effectively utilize the section modulus of the board to support and reinforce the rear parcel board with a lightweight material that reduces deflection, making it possible to provide rear parcels at low cost. It becomes possible. Therefore, it greatly improves the marketability of rear parcels and greatly contributes to reducing the weight and cost of automobiles. In addition, the structure of the reinforcement material is simplified, making it easier to set during molding and improving workability, which also has the effect of reducing costs and improving the quality of the rear parcel.
