Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, depending on the destination, vehicles may be required to be equipped with a spare tire. The spare tire is stored in a spare tire storage section provided below the floor board. In such a vehicle, it is necessary to secure a space for storing the spare tire under the floor board and a space for storing the tonneau cover. In this case, considering the removal and storage of the spare tire and the tonneau cover from the rear of the luggage compartment, it is necessary to provide a storage location for the spare tire and the tonneau cover. That is, both the spare tire and the tonneau cover need to be stored within the reach of the user's hand from the rear of the luggage compartment.

[0006] In addition, it is also conceivable to provide a storage recess for the tonneau cover disclosed in Patent Document 1 between the storage location of the spare tire in the luggage compartment and the rear end of the luggage compartment.

[0007] However, since the storage location of the tonneau cover disclosed in Patent Document 1 is stored with the extension plate portion facing in the vertical direction, the height from the ground to the floor board increases by the width of the extension plate portion, resulting in problems such as a decrease in the luggage loading capacity and poor usability.

[0008] The present invention has been made to solve the above problems, and an object thereof is to provide a luggage compartment structure of a vehicle that can store both a spare tire and a roll-up tonneau cover below the floor board of the luggage compartment and has excellent workability when storing and removing the spare tire and the tonneau cover.

Means for Solving the Problems

[0009] The luggage compartment structure of a vehicle according to one aspect of the present invention is a structure capable of storing a spare tire and a roll-up tonneau cover below the floor board of the luggage compartment. The luggage compartment structure of the vehicle according to this aspect includes a spare tire storage section and a tonneau cover storage section. The spare tire storage section is a part formed below the floor board for storing the spare tire. The tonneau cover storage section is a part formed below the floor board for storing the tonneau cover in a wound-up state.

[0010] The tonneau cover has a cylindrical portion having a cylindrical shape, a sheet portion, and an extension plate portion. The sheet portion is a portion that can be wound up / pulled out with respect to the inside of the cylindrical portion. The extension plate portion is connected to the edge of the sheet portion and is a plate-shaped portion disposed outside the cylindrical portion in a state where the sheet portion is wound around the cylindrical portion.

[0011] The tonneau cover storage portion is a portion between the spare tire storage portion and the rear end of the luggage compartment in the front-rear direction of the vehicle, and includes a portion where the cylindrical portion is disposed and a portion above a part of the spare tire stored in the spare tire storage portion. The extension plate portion is disposed in a direction intersecting the vertical direction of the vehicle so as to cover a part of the spare tire.

[0012] In the luggage compartment structure of the vehicle according to the above aspect, in a state where the spare tire and the tonneau cover are stored below the floor board, the extension plate portion of the tonneau cover is disposed so as to cover above a part of the spare tire. Therefore, in the luggage compartment structure of the vehicle according to the above aspect, while storing both the spare tire and the tonneau cover in the luggage compartment, the size of the storage portion in the front-rear direction can be kept small. That is, in the luggage compartment structure of the vehicle according to the above aspect, compared with the case where the spare tire storage portion and the tonneau cover storage portion are arranged in the front-rear direction with a non-overlapping positional relationship, the spare tire storage portion can be arranged at the rear part of the luggage compartment by the amount that the extension plate portion is disposed above the spare tire. For this reason, in the luggage compartment structure of the vehicle according to the above aspect, it is easy to take in and out the spare tire and the tonneau cover stored in the luggage compartment from the rear of the luggage compartment.

[0013] Further, in the luggage compartment structure of the vehicle according to the above aspect, since the extension plate portion of the tonneau cover is disposed substantially horizontally (in a direction intersecting the vertical direction of the vehicle) so as to cover above the spare tire, compared with the structure disclosed in Patent Document 1 above, there is no problem that the height from the ground to the floor board becomes high, and there is no reduction in the load capacity of the luggage or deterioration in usability.

[0014] Therefore, in the vehicle luggage compartment structure according to the above aspect, both the spare tire and the tonneau cover can be stored below the floor board in the luggage compartment, and the workability when storing and removing the spare tire and the tonneau cover is excellent.

[0015] The luggage compartment structure of the vehicle according to the above aspect being The tonneau cover storage section may have tonneau cover holding members arranged adjacent to both sides and rear of the spare tire when the luggage compartment is viewed in a plan view from above, and the tonneau cover holding members may have front support portions arranged on both sides of the spare tire and supporting a portion of the extension plate portion so as to be spaced apart from the spare tire, and rear support portions arranged rearward of the front support portions and supporting both ends of the tubular portion.

[0016] The vehicle luggage compartment structure of the above-mentioned aspect is equipped with a tonneau cover retaining member having a front support portion and a rear support portion, so that when a spare tire and tonneau cover are stored under the floor board of the luggage compartment, contact between the extension plate portion of the tonneau cover and the spare tire and movement of the tonneau cover in the fore-and-aft direction when the vehicle is accelerating or decelerating can be restricted.

[0017] The luggage compartment structure of the vehicle according to the above aspect being The front support portion is higher than the rear support portion. The support member may be formed to be positioned toward the front support portion and may further include a stepped portion connecting the front support portion and the rear support portion in the front-to-rear direction of the vehicle.

[0018] In the luggage compartment structure for a vehicle according to the above aspect, a step is formed between the front support portion and the rear support portion in the fore-and-aft direction of the vehicle in the tonneau cover holding member. Therefore, in the luggage compartment structure for a vehicle according to the above aspect, it is possible to improve the rigidity of the tonneau cover holding member by ensuring the moment of inertia, compared to a case in which the front support portion and the rear support portion are connected by a flat surface or the like.

[0019] The luggage compartment structure of the vehicle according to the above aspectbeing The tonneau cover holding member may further have a recess provided so as to be recessed toward the front side on the back surface side of the step portion in the thickness direction of the tonneau cover holding member.

[0020] In the cargo compartment structure of the vehicle according to the above aspect, since a recess is formed on the back surface side of the step portion in the tonneau cover holding member, the volume of the tonneau cover holding member can be reduced by the amount of thinning due to the formation of the recess, and the manufacturing cost can be reduced.

[0021] The cargo compartment structure of the vehicle according to the above aspect being The tonneau cover holding member may further have positioning convex portions for positioning in the longitudinal direction and the vehicle width direction of the vehicle, which are provided so as to protrude toward the vehicle body floor side of the cargo compartment more than other portions on the back surface side.

[0022] In the cargo compartment structure of the vehicle according to the above aspect, since the positioning convex portions are provided on the back surface side of the tonneau cover holding member, it is possible to restrict the tonneau cover holding member from moving with respect to the vehicle body floor when the vehicle accelerates or decelerates or changes direction.

[0023] The cargo compartment structure of the vehicle according to the above aspect being The tonneau cover holding member further has a front convex portion disposed on the front side of the front support portion and formed higher than the front support portion toward the upper side. The front convex portion is provided so that there is a gap between the front convex portion and the edge portion on the side where the front convex portion is provided in the extended plate portion in a state where the extended plate portion is placed on the front support portion.

[0024] In the cargo compartment structure of the vehicle according to the above aspect, the tonneau cover holding member is disposed so that there is a gap between the front convex portion and the extended plate portion in a state where the tonneau cover is stored. Therefore, in the cargo compartment structure of the vehicle according to the above aspect, the workability when the user places the extended plate portion of the tonneau cover on the front support portion of the tonneau cover holding member or takes out the placed extended plate portion is excellent.

[0025] The luggage compartment structure of the vehicle according to the above aspect being The tonneau cover holding member may further have a connecting surface portion that connects the rear support portions provided on both sides in the vehicle width direction, the rear support portions are arranged so that a gap is formed between the rear end portion of the cylindrical portion and the rear end of the luggage compartment, and the connecting surface portion is formed so that a gap is formed between the upper surface of the connecting surface portion and the cylindrical portion.

[0026] In the luggage compartment structure of the vehicle according to the above aspect, the tonneau cover holding member is arranged so that a gap is formed between the rear end portion of the cylindrical portion and the rear end of the luggage compartment, and between the cylindrical portion and the connecting surface portion, respectively. Therefore, in the luggage compartment structure of the vehicle according to the above aspect, the user can store or take out the tonneau cover with respect to the tonneau cover storage portion by inserting a finger or a hand through the above gap. Therefore, in the luggage compartment structure of the vehicle according to the above aspect, the workability at the time of storing and taking out the tonneau cover with respect to the tonneau cover storage portion in the luggage compartment is excellent.

[0027] The luggage compartment structure of the vehicle according to the above aspect being , the toner cover holding member may be formed including a foamed resin material.

[0028] In the luggage compartment structure of the vehicle according to the above aspect, since the tonneau cover holding member is formed including a foamed resin material (for example, expanded polystyrene), weight reduction can be achieved and it is easy to mold into various shapes according to the luggage compartment of the vehicle.
