Description

The present invention relates to a luggage compartment structure of a vehicle including a deck board.

Patent Document 1 discloses an example of a luggage compartment structure of a vehicle. An opening is provided at the rear end of the luggage compartment structure. When the back door is closed, the opening is closed by the back door. Further, in the luggage compartment structure, a deck board (luggage board) for placing luggage or the like closes the storage portion from above the vehicle. At the rear end of the deck board, a rear protrusion that bends downward of the vehicle is provided. When the back door is closed, the rear projection portion is sandwiched between the lower end portion of the opening and the back door in the vertical direction of the vehicle. As a result, the displacement of the deck board in the vertical direction of the vehicle is regulated, so that the rattling of the deck board is suppressed. Therefore, the stability of the deck board supported by the luggage compartment is ensured.

However, in the luggage compartment structure disclosed in Patent Document 1, the rear protrusions of the deck board are uniformly formed over the entire width direction of the deck board. This configuration causes an increase in the weight and cost of the deck board, so improvement is desired.

The deck board 20 is supported by the luggage compartment 10 in a predetermined posture based on each of the first luggage compartment form A1, the second luggage compartment form A2, and the third luggage compartment form A3, which will be described later. The deck board 20 has an upper surface 20A and a lower surface 20B. The upper surface 20A and the lower surface 20B face opposite to each other in the thickness direction of the deck board 20. The deck board 20 is composed of a main body layer and a pair of skins. Of the pair of epidermis, one epidermis contains the upper surface 20A and the other epidermis includes the lower surface 20B. Each pair of epidermis is attached to the main body layer. Therefore, the main body layer is sandwiched by a pair of epidermis. The material of the main body layer is, for example, AS resin. The material of the pair of epidermis is, for example, polyethylene terephthalate (PET). The surface of the main body layer may be coated with a synthetic resin layer mixed with glass fibers.

As shown in FIG. 4, the deck board 20 includes a main body portion 21 and a movable portion 22. The main body 21 forms the main part of the deck board 20. As shown in FIGS. 4 and 5, the main body 21 has an end face 20C that faces rearward and is connected to the upper surface 20A and the lower surface 20B. The movable portion 22 is located at the front end of the deck board 20 and is connected to the main body portion 21. The movable portion 22 extends in the vehicle width direction. At the boundary between the main body 21 and the movable portion 22, the main body layer of the deck board 20 is divided. A pair of skins of the deck board 20 are connected to the boundary. As a result, the movable portion 22 can pass through the boundary and bend around the axis L along the vehicle width direction.

As shown in FIGS. 4 and 5, the main body 21 of the deck board 20 has a convex portion 211. The convex portion 211 projects rearward from the end surface 20C of the main body portion 21. In the example shown by the luggage compartment structure, the convex portions 211 consist of a pair of regions located apart from each other on the left and right sides. The configuration of the convex portion 211 is not limited to this configuration, and may be, for example, one integrated region. The convex portion 211 has an inclined surface 211A. The inclined surface 211A is connected to the lower surface 20B of the main body 21. Based on each of the first luggage compartment form A1 and the second luggage compartment form A2, which will be described later, when the main body portion 21 takes a posture in which the lower surface 20B faces the main surface 111 of the rear floor 11, the inclined surface 211A is the vehicle from the end surface 20C. It slopes diagonally upward toward the rear.

Next, the first luggage compartment form A1, the second luggage compartment form A2, and the third luggage compartment form A3 adopted by the main luggage compartment structure will be described.

In the first luggage compartment form A1, as shown in FIG. 6, the deck board 20 is supported by the rear floor 11. As a result, the deck board 20 is stored in the lower stage of the luggage compartment 10. As shown in FIG. 7, the main body 21 of the deck board 20 is in a horizontal posture when the lower surface 20B is in contact with the main surface 111. At this time, the movable portion 22 of the deck board 20 is bent upward along the first inclined surface 122A and the second inclined surface 122B of the guide portion 122 with the axis L as the rotation axis. The main body 21 is in a form of closing the dug portion 112 of the rear floor 11 from above the vehicle.

In the second luggage compartment form A2, as shown in FIG. 8, the main body 21 of the deck board 20 is supported by a pair of first support 121 and second support 131. The movable portion 22 of the deck board 20 is supported by a pair of auxiliary support portions 123. As a result, the deck board 20 is stored in the upper stage of the luggage compartment 10.

As shown in FIG. 9, in the second luggage compartment form A2, the first support surface 121A of the pair of first support portions 121, the second support surface 131A of the second support portion 131, and the pair of auxiliary support portions 123. The lower surface 20B of the deck board 20 is in contact with the auxiliary support surface 123A. As a result, the deck board 20 takes a horizontal posture with both the main body 21 and the movable portion 22, and the lower surface 20B of the main body 21 faces the main surface 111 of the rear floor 11. When the deck board 20 takes such a posture, at least a part of the convex portion 211 of the main body portion 21 of the deck board 20 is accommodated in the concave portion 132. At this time, the position of the upper surface 20A of the deck board 20 is substantially equal to the position of the top surface 13A of the trailing edge member 13 in the vertical direction of the vehicle. As shown in FIG. 10, when the opening of the luggage compartment 10 is closed by the back door 40, the convex portion 211 overlaps the lower end of the back door 40 when viewed from above the vehicle. As a result, in the vertical direction of the vehicle, the convex portion 211 is sandwiched between the bottom surface 132A of the concave portion 132 and the lower end of the back door 40. Further, each of the pair of regions of the convex portion 211 faces any of the pair of side surfaces 132B of the concave portion 132.

As shown in FIG. 11, the third luggage compartment form A3 is formed by inserting both ends of the deck board 20 in the vehicle width direction into the groove portions 121B of the pair of first support portions 121 from the upper side of the vehicle to the lower side of the vehicle. To. As a result, the deck board 20 is stored in the luggage compartment 10 in a leaning state. As shown in FIG. 12, the front end of the movable portion 22 of the deck board 20 is supported by the second inclined surface 122B of the guide portion 122. The rear end of the movable portion 22 is supported by the first inclined surface 122A of the guide portion 122. At the same time, both ends of the main body 21 of the deck board 20 in the vehicle width direction are supported by the grooves 121B of the pair of first support 121. At this time, the movable portion 22 is bent upward along the first inclined surface 122A and the second inclined surface 122B with the axis L as the rotation axis.

Next, the action and effect of the main luggage compartment structure will be described.

The main luggage compartment structure includes a luggage compartment 10 and a deck board 20 supported by the luggage compartment 10. The trailing edge member 13 included in the component of the luggage compartment 10 has a top surface 13A and a recess 132. The top surface 13A faces the upper side of the vehicle and defines the lower end of the opening which leads to the luggage compartment 10 and is closed by the back door 40. The recess 132 is recessed from the top surface 13A and leads to the luggage compartment 10. The deck board 20 has an end face 20C facing rearward and a convex portion 211 projecting rearward from the end face 20C. In the main luggage compartment structure, when the deck board 20 is supported by the luggage compartment 10 in a predetermined posture based on the second luggage compartment form A2, at least a part of the convex portion 211 is accommodated in the concave portion 132.

In this case, when the opening leading to the luggage compartment 10 is closed by the back door 40, the convex portion 211 is sandwiched between the bottom surface 132A of the concave portion 132 and the lower end of the back door 40 in the vertical direction of the vehicle. It becomes a composition. When the deck board 20 is displaced in the vertical direction of the vehicle, the displacement is regulated by the convex portion 211 coming into contact with either the bottom surface 132A or the lower end of the back door 40. As a result, the convex portion 211 serves as a means for regulating the displacement, so that rattling of the deck board 20 is suppressed. The volume of the convex portion 211 can be smaller than the volume of the conventional displacement regulating means applied to the deck board 20. Further, by making the protruding length of the convex portion 211 as large as possible, the effect as a means for regulating the displacement is further enhanced. From the above, according to the main luggage compartment structure, when the deck board 20 is supported by the luggage compartment 10 in a predetermined posture, it is possible to ensure the stability of the deck board 20 and to reduce the weight. ..

At the same time, when the deck board 20 is supported by the luggage compartment 10 in a predetermined posture based on the second luggage compartment form A2, and at least a part of the convex portion 211 is accommodated in the concave portion 132, the convex portion 211 is accommodated. It faces the pair of side surfaces 132B of the recess 132. As a result, when the deck board 20 is displaced in the vehicle width direction, the convex portion 211 comes into contact with any of the pair of side surfaces 132B, and the displacement is regulated. Therefore, since the convex portion 211 serves as a means for regulating the displacement, lateral displacement of the deck board 20 can be suppressed.

Further, in the main luggage compartment structure, when the deck board 20 is supported by the luggage compartment 10 in a predetermined posture based on the second luggage compartment form A2 and the third luggage compartment form A3, the convex portion 211 holds a shopping bag or the like. It can be used as a means for hooking. In particular, in the third luggage compartment form A3, when the shopping bag or the like is located in front of the vehicle with respect to the main body 21 of the deck board 20, by providing the inclined surface 211A on the main body 21, the shopping bag or the like becomes the convex portion 211. Easy to hook.

The present invention is not limited to the embodiments described above. The specific configuration of each part of the present invention can be freely redesigned.
