Description

The present invention relates to a vehicle structure.

Patent Document 1 discloses a vehicle structure having a luggage compartment. This vehicle structure includes a luggage compartment floor and a luggage box arranged on the luggage compartment floor. The luggage box is a luggage tray having multiple box sections. The multiple box sections allow small items to be classified and organized.

The luggage tray has a front wall, a rear wall, left and right side walls, and a bottom wall, and is box-shaped with an open top. A deck board is placed on top of the luggage tray. The luggage tray is required to have a certain level of strength because it is subjected to the weight of the deck board and the luggage on the deck board.

JP 2016-88318 A

Although luggage trays make it easier to organize small items in the luggage compartment, they reduce the volume of the luggage compartment. There is a need to increase the volume of the luggage compartment while maintaining the convenience of a luggage tray, especially in compact cars or light vehicles.

One of the objectives of the present invention is to provide a vehicle structure that can increase the volume of the luggage compartment while maintaining a certain level of strength.

<1> A vehicle structure according to one aspect of the present invention includes:
A rear floor that constitutes the bottom of the luggage compartment;
A luggage tray is placed on the rear floor,
The rear floor has a recess recessed downwardly of the vehicle and a base portion other than the recess,
The luggage tray is composed of a front wall located at the front side of the vehicle and two side walls,
At least a portion of the lower portion of the front wall is disposed within the recess;
At least a portion of the lower portion of the side wall rests on the base portion.

<2> In the vehicle structure described in <1> above,
A deck side trim that constitutes an inner wall of the luggage compartment is provided.
The front, rear and side portions of the sidewall may be surrounded by the deck side trim.

The luggage tray provided in the vehicle structure of <1> above is composed of a front wall and two side walls, and does not have a bottom wall or a rear wall. In other words, the luggage tray is U-shaped when viewed from above, consisting of a front wall and two side walls. The volume of this luggage tray is smaller than that of conventional luggage trays. Therefore, the vehicle structure of <1> above can increase the capacity of the luggage compartment while obtaining the effect of the luggage tray of making it easier to organize small items. Also, since at least a portion of the lower part of the side wall of the luggage tray is placed in a part other than the recess, the recess can be used more widely.

The luggage tray, which has a front wall and two side walls connected in a U-shape, has a certain level of strength. In addition, at least a portion of the lower part of the front wall of the luggage tray is placed within the recess and supported by the recess, making it easier for the luggage tray to withstand loads from above.

In the vehicle structure of <2> above, the side walls of the luggage tray are surrounded and fixed on three sides by the deck side trim. The three sides are the front, rear, and sides. The luggage tray is surrounded on three sides, so it can stably receive the load from the deck board and is less likely to shift from its designated position. In addition, the luggage tray is less likely to be damaged because excessive stress is prevented from acting on the joints between the side walls and the front wall of the luggage tray due to the luggage tray shifting.

FIG. 1 is a schematic diagram of a vehicle structure described in embodiment 1. FIG. 2 is a cross-sectional view taken along line II-II of FIG. FIG. 3 is a partially enlarged view of FIG.

Below, an example of an embodiment of the vehicle structure of the present invention will be described with reference to the drawings. In the drawings, "FR" indicates the front of the vehicle, "RR" indicates the rear of the vehicle, "RH" indicates the right side of the vehicle, and "LH" indicates the left side of the vehicle. The same reference numerals in the drawings indicate the same or equivalent parts. The sizes of the components shown in each drawing are expressed for the purpose of clarifying the explanation, and do not necessarily represent the actual dimensions. Note that the present invention is not limited to the examples below, but is set forth in the claims, and includes all modifications within the meaning and scope equivalent to the claims.

<Embodiment 1>
Fig. 1 is a schematic diagram of a portion of a luggage compartment at the rear of a vehicle as viewed from inside the vehicle. The vehicle structure 1 includes a rear floor 2 that constitutes the bottom surface of the luggage compartment. A deck side trim 4 is disposed to the right of the rear floor 2, and a lower back trim 5 is disposed behind the rear floor 2. Although not shown in Fig. 1, a deck side trim is also disposed to the left of the rear floor 2. The deck side trim 4 and the lower back trim 5 also constitute part of the luggage compartment. The vehicle structure 1 of this example further includes a luggage tray 3 placed on the rear floor 2.

<Rear floor>
The rear floor 2 has a recess 20 that is locally recessed in the center of the vehicle width, and a base portion 21 other than the recess 20. In this example, the base portion 21 surrounds the right, front, and left of the recess 20. When viewed from above, the base portion 21 is roughly C-shaped. In FIG. 1, only a portion of the base portion 21 that is located to the right of the recess 20 is visible. The cross-sectional view of FIG. 2 illustrates a portion of the base portion 21 that is located in front of the recess 20. As shown in FIG. 2, a protective sheet 25 such as a carpet may be placed in the recess 20.

Luggage Tray
As shown in Fig. 1, the luggage tray 3 is composed of a front wall 30 and two side walls 31, 32 that are connected in a U-shape when viewed from above. The luggage tray 3 does not have a bottom wall or a rear wall, and has a smaller volume than a conventional luggage tray. Therefore, the capacity of the luggage compartment in which the luggage tray 3 of this embodiment is arranged is larger than the capacity of a luggage compartment in which a conventional luggage tray is arranged. Moreover, as shown in the cross-sectional view of Fig. 2, the luggage tray 3 does not have a bottom wall or a rear wall, so that the recess 20 can be used widely.

As shown by the phantom lines in FIG. 2, the deck board 6 is placed on the luggage tray 3. The front part of the deck board 6 is supported from below by the upper surface of the front wall 30 of the luggage tray 3. The sides of the deck board 6 are supported from below by the upper surfaces of the side walls 31 and 32. The rear part of the deck board 6 is supported from below by the lower back trim 5.

1, the front wall 30 has a plurality of box sections 35. The number of the box sections 35 is not particularly limited. The box sections 35 make it easy to organize small items. As shown in FIG. 2, at least a part of the lower part of the front wall 30 is placed on the recess 20 of the rear floor 2. The front part of the recess 20 has a slope that slopes downward toward the rear of the vehicle. The outer peripheral surface of the front wall 30 in this example is shaped to follow the slope. The front wall 30 fits into the recess 20 and is placed on the recess 20, so that the front wall 30 is supported by the recess 20. Therefore, even if a load acts on the deck board 6 arranged on the luggage tray 3, the load acting on the front wall 30 is easily distributed to the recess 20. The front wall 30 in this example is placed on the bottom of the recess 20 with the protective sheet 25 sandwiched therebetween, but may be floating above the bottom of the recess 20.

As shown in FIG. 1, the upper surfaces of the side walls 31 and 32 are provided with a plurality of protrusions 37 that protrude upward from the upper surfaces. The number of protrusions 37 is not particularly limited. In this example, the side walls 31 and 32 are each provided with two protrusions 37 at the front and rear. The rear protrusions 37 fit into recesses formed in the underside of the deck board 6 (see FIG. 2) to suppress rattling of the deck board 6. The rear protrusions 37 have a flat upper surface. A cushion layer made of nonwoven fabric or the like may be disposed on the upper surface of the rear protrusions 37. The deck board 6 is disposed so that the front part of the deck board 6 contacts the rear part of the front protrusions 37, and the front protrusions 37 suppress rattling of the deck board 6.

At least a portion of the lower portion of the side walls 31, 32 is placed on the base portion 21. In this example, only the side wall 31 on the right side of the vehicle will be described. The left side wall 32 may have a similar configuration to the right side wall 31. In this example, the entire lower portion of the side wall 31 is placed on the base portion 21 to the right of the recess 20. In other words, the side wall 31 is not fitted into the recess 20. Since the side wall 31 is not fitted into the recess 20, the recess 20 can be used more widely.

The side wall 31 in this example is further configured to be surrounded by the deck side trim 4. The rear portion of the deck side trim 4 in this example curves toward the lower back trim 5 and wraps around to the rear of the side wall 31. This configuration will be described with reference to the partially enlarged view of FIG. 3. FIG. 3 is an enlarged view of the vicinity of the side wall 31 in the luggage compartment. As shown in FIG. 3, the front portion 31F, side portion 31S, and rear portion 31B of the side wall 31 are surrounded by the deck side trim 4.

The front surface 31F is the portion of the side wall 31 of the luggage tray 3 that has a surface facing the front of the vehicle. In this example, the front surface 31F is formed in a first protruding portion 38 that protrudes forward of the vehicle. In this example, the upper portion of the first protruding portion 38 forms the protruding portion 37. In this example, the front surface 31F is the portion of the side wall 31 that has the most forward surface, but it does not necessarily have to be the portion that has the most forward surface.

A front shelf 40F of the deck side trim 4 is disposed in front of the front portion 31F. The front shelf 40F protrudes leftward from the inner peripheral surface 40 of the deck side trim 4. The front shelf 40F is in contact with or close to the front portion 31F, and restricts the forward movement of the luggage tray 3. A cushioning material made of nonwoven fabric or the like may be disposed between the rear end surface of the front shelf 40F and the front portion 31F. The cushioning material may be attached to at least one of the front shelf 40F and the front portion 31F.

The side surface portion 31S is a portion of the side wall 31 of the luggage tray 3 that has a surface facing the right of the vehicle. In this example, the side surface portion 31S is configured by a portion that locally protrudes to the right from the outer circumferential surface of the side wall 31. In this example, the side surface portion 31S is the portion of the side wall 31 that has the surface that is located on the rightmost side, but it does not necessarily have to be the portion that has the surface that is located on the rightmost side.

The side portion 31S is in contact with or close to the inner peripheral surface 40 of the deck side trim 4, and the movement of the luggage tray 3 to the right is restricted. A cushioning material may be disposed between the side portion 31S and the inner peripheral surface 40. The cushioning material may be attached to at least one of the inner peripheral surface 40 and the side portion 31S.

The rear surface portion 31B is the portion of the side wall 31 of the luggage tray 3 that has a surface facing the rear of the vehicle. In this example, the rear surface portion 31B is formed by the rear end portion of the side wall 31 excluding the second protruding portion 39 described below. In this example, the rear surface portion 31B is not the rearmost surface of the side wall 31.

A rear shelf 40B of the deck side trim 4 is disposed behind the rear portion 31B. The rear shelf 40B protrudes forward from the inner peripheral surface 40 of the deck side trim 4. The rear shelf 40B is in contact with or close to the rear portion 31B, and restricts rearward movement of the luggage tray 3. A cushioning material may be disposed between the front end surface of the rear shelf 40B and the rear portion 31B. The cushioning material may be attached to at least one of the rear shelf 40B and the rear portion 31B.

In this example, a second protruding portion 39 that protrudes rearward is formed at the rear end of the side wall 31. The upper surface of the second protruding portion 39 is flush with the upper surface of the portion other than the second protruding portion 39. The lower surface of the second protruding portion 39 is placed on the upper end surface of the rear shelf 40B. The second protruding portion 39 restricts the downward movement of the side wall 31. The second protruding portion 39 supported by the rear shelf 40B receives the load from the deck board 6 (FIG. 2). In addition to the rear surface portion 31B, the rear end surface of the second protruding portion 39 may also function as a rear surface portion that restricts the rearward movement of the luggage tray 3. In that case, the surface of the inner peripheral surface 40 of the deck side trim 4 that faces forward abuts and stops the second protruding portion 39.

In the configuration described with reference to FIG. 3, the side walls 31 of the luggage tray 3 are surrounded and fixed on three sides. Therefore, the luggage tray 3 can stably receive the load from the deck board 6 and is unlikely to shift from its specified position on the rear floor 2. In addition, even if the deck board 6 placed on the luggage tray 3 attempts to move forward, excessive stress is unlikely to act on the joint between the side walls 31 and the front wall 30. Therefore, the luggage tray 3 is unlikely to be damaged.
