Description

  The present invention relates to a power storage device mounting structure of a vehicle suitable for mounting a battery such as a lithium ion secondary battery or a nickel hydrogen secondary battery or other power storage device in a vehicle such as a hybrid vehicle or an electric vehicle.

As a specific example of the power storage device mounting structure of a vehicle, there are structures described in Patent Documents 1 and 2.
In the structures described in these documents, a vehicle seat is installed on a cabin floor portion, and a storage device such as a battery is disposed in a space below a pedestal portion that supports the seat cushion of the vehicle seat. It is set up. According to such a configuration, it is possible to arrange the power storage device in the vehicle interior in a space efficient manner by effectively using the installation location of the vehicle seat.
Moreover, in patent document 2, a waterproof carpet is laid on the said base part, and the upper direction of the electrical storage apparatus is covered by this waterproof carpet. According to such a configuration, when a liquid such as water is drained on the seat cushion, the water is prevented or prevented from flowing down onto the power storage device, thereby protecting the power storage device.

  However, in the above-mentioned prior art, as will be described next, there is still room for improvement.

First, although the waterproof carpet may prevent the liquid from getting caught in the storage device if the amount of liquid flowing onto the waterproof carpet is small, a large amount of liquid is on the pedestal and on the waterproof carpet. When it flows, the liquid can not be appropriately prevented from flowing toward the power storage device, and there is a possibility that the liquid may be applied to the power storage device. For example, a relatively large sized cooler box having a capacity of about 18 liters may be loaded into the passenger compartment, and the passenger may accidentally overturn the cooler box. In this case, if a large amount of liquid spills on the pedestal portion and the waterproof carpet at the same time, the liquid may flow along the pedestal portion or the edge portion or the back surface of the waterproof carpet toward the power storage device. In addition, the waterproof carpet is generally provided with an opening for passing the seat belt anchor or inner belt. However, when a large amount of the liquid flows into the opening, the liquid flows into the storage device. It may flow toward you. From the viewpoint of thoroughly protecting the storage device, it is desirable to appropriately prevent the storage device from touching the liquid (water) in the manner as described above.
Second, when the seat cushion of the vehicle seat is a so-called dive down system, the seat cushion supporting the seat cushion is engaged to fix the seat cushion when the seat cushion is disposed on the pedestal portion It is customary for the claws to be provided in a projecting manner. Here, if the engaging claws are provided in a state of projecting largely above the upper surface of the pedestal portion, the flatness of the upper surface of the pedestal portion is impaired, so the seatback may be used during dive down of the seat cushion. In the case of adopting a method (double fold method) in which the seatback is lowered onto the pedestal portion, there is a problem that the seatback and the engaging claws interfere with each other to cause a hindrance to falling the seatback to a flat state. In addition, when the engaging claws project above the pedestal during dive-down of the seat cushion, there is a possibility that the clothes of the occupant or the like may be caught on the engaging claws. Therefore, it is desirable to prevent such a thing appropriately.

  The present invention has been conceived under the circumstances as described above, and can appropriately prevent or suppress water splashing of the power storage device, as well as hindering the engaging claws for fixing the seat cushion of the vehicle seat. It is an object of the present invention to provide a power storage device mounting structure of a vehicle that can be provided in a state without power.

  In order to solve the above problems, the present invention takes the following technical measures.

  The storage device mounting structure of a vehicle provided by the present invention is a seat portion for a seat on which a seat cushion of a vehicle seat is placed and on which an engagement claw for fixing the seat cushion is provided, and the seat portion A storage device mounting structure of a vehicle, comprising: a storage device disposed in a space below the storage space, and the liquid flowing down the upper side of the pedestal or the liquid flowing toward the upper side of the pedestal And an drainage groove formed on the upper surface and capable of being led to a location not directed to the electric storage device, the engagement claw being located inside the drainage groove. It is characterized.

According to such a configuration, the following effects can be obtained.
First, when the liquid is drained in the vehicle compartment and the liquid flows down to the upper side of the pedestal or flows upward, the concave portion for draining at least a part of the liquid After flowing into the groove, it is possible to lead it to a place which is not directed to the power storage device. Therefore, even if a large amount of liquid spills on the pedestal at one time, the liquid on the pedestal is prevented from accumulating, for example, the liquid on the pedestal is at the edge of the pedestal. It is possible to prevent or suppress traveling toward the power storage device side by passing the back side. As a result, according to the present invention, it is possible to make the storage protection performance of the storage device superior as compared with the prior art, and to appropriately protect the storage device.
Second, since the engaging claws for fixing the seat cushion are located inside the drainage concave groove, the engaging claws can be prevented from largely protruding on the upper surface or the like of the pedestal portion. Therefore, for example, when the seat cushion is dived down and then the seat back is lowered onto the pedestal portion, it is possible to solve the problem that the engaging claws cause a hindrance. In addition, it is possible to make it unlikely that the clothes or the like of the occupant get caught on the engagement claws.

The waterproof carpet 5 has a laminated structure in which, for example, the front side is a non-woven layer and the back side is a resin layer, and the non-woven layer itself is highly flexible but the resin layer is a relatively hard layer with low flexibility. It is. By providing the resin layer on the waterproof carpet 5, shape retention capable of maintaining each part of the waterproof carpet 5 in a predetermined shape is secured. In FIG.
The waterproof carpet 5 includes a main portion 5a located on the front side of the vehicle, first and second auxiliary portions 5b and 5c connected to the rear portion, and a pair of left and right drainage grooves 52.

  The main portion 5 a of the waterproof carpet 5 is a portion which is placed on the pedestal portion 40 and underlays the seat cushion 31. The main portion 5a is provided with a pair of openings 50 for passing the seat belt anchor (not shown) or the inner belt. Preferably, the opening 50 is closed by an appropriate member so that a large amount of water can not pass through, but it is difficult to completely close the opening 50, and when liquid flows on the main portion 5a. It is desirable to prevent the liquid from entering the opening 50. The first and second auxiliary portions 5b and 5c are respectively stacked and fixed on the front surface of the upstanding wall portion 1c and the upper surface of the rear floor portion 1b.

  The pair of left and right drainage grooves 52 discharge the liquid from the waterproof carpet 5 onto the inclined surface 11 a so that the liquid flowing down onto the waterproof carpet 5 (including the pedestal portion 40) does not get trapped on the storage device 2. It is a part for draining and has an upward opening shape. As well represented in FIG. 4, the drainage groove 52 is formed in a stepped shape so that a part of the waterproof carpet 5 has a downward convex portion 52b having a triangular or rectangular cross section on the lower surface side. It is provided by forming, and it extends in the vehicle width direction so as to be located in the gap C between the pedestal 40 and the upstanding wall 1 c. According to such a configuration, it is possible to prevent the downward convex portion 52b from interfering with the pedestal portion 40 and the upstanding wall portion 1c, and to appropriately provide the drainage groove 52, and the bottom portion of the drainage groove 52 can be provided. The height position can be set to a height position lower than the top surface of the pedestal 40.

  Preferably, the drainage groove 52 is formed so as to be wider as it goes outward in the vehicle width direction, and to be deeper. The outer end (termination) of the drainage groove 52 is located above the inclined surface 11a of the floor side raised portion 11, and the liquid flowing into the drainage groove 52 is configured to flow down on the inclined surface 11a. ing.

  The engagement claws 48 for fixing the seat cushion are provided at the rear of the pedestal 40, for example, in a pair of left and right. However, each engaging claw 48 is located inside the drainage groove 52. More specifically, as well shown in FIG. 5 (b), the side wall portion of the drainage groove 52 of the waterproof carpet 5 is provided with a hole 59, and the engagement claw 48 is By inserting this hole 59, the inside of the drainage ditch 52 is exposed.

  As described above, the vehicle seat S is a double-fold type, and the seat cushion 31 is dived down from the top of the pedestal portion 40 to the front side of the vehicle as shown by a virtual line in FIG. It is possible. In this state, it is possible to fold the seat back 30 onto the pedestal 40. As a result, it is possible to widen the cargo space on the rear floor portion 1b and to set the seat back 30 substantially flat with respect to the rear floor portion 1b. When the seat cushion 31 is dived down, the waterproof carpet 5 is in a state of covering the upper surface of the pedestal portion 40 and its peripheral portion, so that it is possible to improve the appearance of these portions.

  In the present embodiment, the engagement claws 48 are portions for preventing the seat cushion 31 from inadvertently jumping up at the time of a rear collision of the vehicle or the like. As shown in FIGS. 5B and 5C, the seat cushion 31 is provided with an engaged portion 35 which is engaged with the engagement claw 48 at the time of rear end collision or the like.

As shown in FIGS. 3 and 4, preferably, the front portion of the rear side waterproof carpet 8 laid on the rear floor portion 1b is adhered to the rear surface portion of the seat back 30 (other than FIGS. 3 and 4) Not shown in the drawings). The width in the vehicle width direction of the rear side waterproof carpet 8 is the same as the width in the same direction of the seat back 30, and prevents the water spilling on the rear floor portion 1b from flowing downward to the seat back 30 as it is. Play a role. However, as described later, water spilling on the rear floor portion 1b bypasses the rear waterproof carpet 8 and flows toward the vehicle front side.

  Next, the operation of the power storage device mounting structure A of the vehicle will be described.

  In one mode when the occupant removes water in the vehicle compartment, for example, a container such as a relatively large sized cooler box is brought into the vehicle compartment and the container is turned over, so that the main part of the waterproof carpet 5 A large amount of water may spill at one time on 5a (upper side of the pedestal portion 40). In the case where the seat cushion 31 is placed on the main portion 5 a of the waterproof carpet 5, even if the water is thrown off on the seat cushion 31, the water overflows to the lower side of the seat cushion 31. , Flowing on waterproof carpet 5.

  When the above-described situation occurs, a large amount of water can flow into the drainage ditch 52. The water which has flowed into the drainage groove 52 flows down onto the slope 11 a of the floor side ridge 11 after being guided to the outer end side. Therefore, the water will flow outward in the vehicle width direction of the floor side raised portion 11, and will not flow toward the power storage device 2 side. On the other hand, as described above, if drainage is performed from the top of the pedestal 40 and the top of the waterproof carpet 5 to the outside using the drainage groove 52, for example, the opening 50 for passing the anchor or inner belt of the seat belt. It is also possible to prevent the flow of much water into the space or the flow of water from the edge of the pedestal 40 or the waterproof carpet 5 to the electric storage device 2 along the lower surface.

  On the other hand, as another mode in the case where the occupant makes water in the vehicle interior, it is also possible to make more water on the rear floor portion 1b on the rear side of the vehicle than the seatback 30, and this water flows to the front side of the vehicle. possible. In this case, a part of the water bypassing the rear side waterproof carpet 8 passes through the lower gap of the seat back 30, etc., and sequentially over the second auxiliary portion 5c and the first auxiliary portion 5b of the waterproof carpet 5. After flowing, it reaches on the main part 5a (upper side of the pedestal part 40). Further, the other part of the water flows so as to pass through the outer side of the seat back 30 in the vehicle width direction, and reaches the upper surface portion of the floor side raised portion 11 from the upstanding wall portion 1 c.

On the other hand, as for the water flowing toward the main portion 5a of the waterproof carpet 5 (the upper side of the pedestal portion 40), the drainage ditch 52 is used on the inclined surface 11a as in the case described above. It can flow down. On the other hand, water that has reached the upper surface portion of the floor side raised portion 11 from the upstanding wall portion 1 c can flow to the vehicle width direction outward side of the floor side raised portion 11 along the inclined surface 11 a as it is. Therefore, the flow of water toward the storage device 2 is appropriately prevented or suppressed.
As described above, in the present embodiment, not only when a large amount of water falls on the seat cushion 31 of the vehicle seat S or on the main portion 5a of the waterproof carpet 5, the vehicle is further forward from the rear floor portion 1b. Even when a large amount of water flows, it is possible to appropriately prevent the storage device 2 from being flooded.

  As described above, the engaging claws 48 for fixing the seat cushion are located inside the drainage recessed groove 52, and the engaging claws 48 do not greatly protrude on the upper surface of the pedestal portion 40 or the like. ing. Therefore, when the seat cushion 31 is dived down and then the seat back 30 is lowered onto the pedestal portion, it is possible to solve the problem that the engaging claws 48 cause a hindrance. It is also possible to reduce the possibility that the clothes or the like of the occupant get caught in the engagement claws 48.

  The present invention is not limited to the contents of the embodiments described above. The specific configuration of each part of the power storage device mounting structure of a vehicle according to the present invention can be variously designed and changed within the intended scope of the present invention.

In the above-mentioned embodiment, although the drainage ditch | groove 52 is provided in the waterproof carpet 5, it is not limited to this. The drainage ditch may be provided in a storage device cover member (for example, a simple resin sheet, a resin plate, a metal plate, etc.) having a different configuration from the waterproof carpet 5. Furthermore, for example, a bowl-shaped member is provided in the gap C between the pedestal portion 40 and the upstanding wall portion 1c, and the recess on the upper surface opening of the bowl-shaped member is used as a drainage ditch intended by the present invention. it can. The drainage ditch in the present invention is basically an upper surface opening capable of guiding the liquid that has fallen to the upper side of the pedestal or the liquid that flows toward the upper side of the pedestal to a location that does not direct it to the power storage device. It should just be provided as a groove-shaped concave groove.
Moreover, in the above-mentioned embodiment, although it is set as the structure which a liquid flows down on the inclined surface 11a of the floor side raised part 11 from the ditch | groove 52 for drainage, this invention is not limited to this, The liquid may be allowed to flow to the location of Although it is preferable that the drainage ditch has a width that becomes wider toward the end side (outer end side) and a depth that is deeper, it is not limited to this. For example, the width and the depth may be substantially the same. It may be. At least one drainage groove may be provided, and the specific number and position thereof are not limited.
