Description

Vehicle body structure
Technical Field
The present invention relates to a vehicle body structure.
This application claims priority based on application Ser. No. 2021-051934 filed on the sun at 3/25/2021, and the contents of which are incorporated herein by reference.
Background
For example, a vehicle that travels using an electric motor as a drive source, such as a hybrid vehicle, is equipped with a power storage device that supplies electric power to the electric motor. The power storage device is mounted on the rear of the vehicle in a rear seat (hereinafter referred to as a seat), for example, and stores a battery in a casing.
Here, for example, a luggage room tray is provided behind the seat, and a luggage room plate is disposed above the luggage room tray. The luggage compartment tray is formed to be recessed downward with respect to the luggage compartment plate. A storage space is formed between the luggage tray and the luggage board, and the electric storage device is stored in the storage space.
Further, a gap is formed between the front end portion of the luggage board and the bottom plate, and the gap is partitioned by the partition member. Therefore, for example, the partition member can prevent the articles on the vehicle compartment side from falling into the storage space through the gap (see, for example, international publication No. 2016/125388).
Disclosure of Invention
However, in the structure of international publication No. 2016/125388, a separate partition member needs to be provided to separate the space between the front end portion of the luggage board and the bottom board. This hinders suppression of the number of parts.
In addition, in order to separate the front end portion of the luggage board from the bottom board, an extra space for disposing the partition member needs to be secured, and there is room for improvement from this viewpoint.
An object of an aspect of the present invention is to provide a vehicle body structure capable of partitioning a storage space for storing an electric storage device from a vehicle compartment without increasing the number of components and without securing an extra space.
In order to achieve the above object, a vehicle body structure according to an aspect of the present invention has the following configuration.
(1) A vehicle body structure according to an aspect of the present invention includes: a power storage device (e.g., power storage device 20 of an embodiment) disposed in a recess (e.g., trunk room tray 18 of an embodiment) formed at the rear of a vehicle (e.g., vehicle 10 of an embodiment) with respect to a seat (e.g., seat 15 of an embodiment) of the vehicle; a guide member (e.g., the guide member 64 of the embodiment) that extends from an upper surface of the power storage device (e.g., the upper guide portion 87 of the embodiment) toward the front and the lower of the vehicle, wherein a carpet (e.g., the carpet 17 of the embodiment) that covers a floor (e.g., the floor panel 14 of the embodiment) of the vehicle extends above the guide member.
According to the aspect (1) described above, the guide member extends forward and downward from the upper surface of the power storage device. The guide member is located rearward of the seat. The carpet is extended from the front of the guide member to the upper side of the guide member from the vehicle compartment side. The carpet is laid in such a manner as to cover the floor of the vehicle.
Therefore, for example, in a state where the seat is lowered in a state where the seatback (backrest) of the seat is tilted forward, that is, in a state where the seat is lowered, the gap between the seat and the power storage device can be closed. Thus, the storage space for disposing (storing) the recess of the power storage device can be partitioned from the vehicle compartment by the carpet without increasing the number of components and without securing an extra space. Therefore, it is possible to prevent the object from falling into the recess without providing a partition member as in the conventional case.
Further, for example, the inflow of air flowing out of the power storage device into the vehicle interior can be suppressed. Further, the heat generated from the power storage device can be suppressed from being transmitted to the vehicle interior.
(2) In the aspect (1) above, the vehicle body structure may include: an air intake unit (for example, air intake unit 41 according to the embodiment) that takes in air for cooling an electric storage element (for example, battery cell 47 according to the embodiment) of the electric storage device; and an exhaust unit (for example, a third exhaust unit 44 according to the embodiment) that exhausts the air after the heat exchange with the electricity storage element, the exhaust unit being provided at a position of the vehicle behind the guide member and opening toward the front of the vehicle.
According to the aspect (2) described above, the exhaust portion is opened forward, and the exhaust portion is provided rearward of the guide member. The carpet extends from above the cabin-side guide member. Therefore, a carpet is disposed in front of the exhaust unit. This can prevent the exhaust air having a high temperature from directly flowing into the vehicle compartment (passenger compartment), and can suppress the deterioration of the air conditioning comfort of the passenger.
(3) In the aspect (2) described above, the vehicle body structure may include a charging plug located on a side of an upper surface (for example, a cover 61 of the embodiment) of the power storage device, a support member (for example, a support member 37 of the embodiment) provided on a vehicle width direction side of the guide member and supporting a luggage room panel (for example, a luggage room panel 16 of the embodiment) arranged above the power storage device may be arranged in a position in the vehicle located in front of the charging plug.
According to the aspect (3) described above, the support member that supports the luggage room plate is provided on the vehicle width direction side of the guide member. By connecting the support member to the vehicle width direction side of the guide member, it is possible to make it more difficult for exhaust air having a high temperature to flow into the vehicle interior, and it is possible to further improve the air conditioning comfort of the passenger.
In addition, the support member is provided in front of the charging plug. Therefore, it is not necessary to cover the charging plug with the guide member extending over the entire region of the power storage device in the vehicle width direction. This makes it possible to easily reach the charging plug, for example, during maintenance and inspection.
(4) In the aspect (2) or (3), the vehicle body structure may include: a housing portion (e.g., housing portion 32 of the embodiment) that houses the electric storage element and has an open upper surface (e.g., upper surface 32a of the embodiment); a cover portion (e.g., cover portion 36 of an embodiment) that covers the upper surface, wherein the cover portion has an exhaust passage connecting portion that is connected to an exhaust passage, the exhaust passage connecting portion being formed on a vehicle front side of the cover portion, and the guide member is fixed to the upper surface of the cover portion and overlaps with the exhaust passage connecting portion in a plan view of the vehicle and a front view of the vehicle.
According to the aspect (4) described above, the guide member is fixed to the upper surface of the cover portion, and the guide member is overlapped (overlapped) with the exhaust passage connecting portion in a vehicle plan view and a vehicle front view. Therefore, the exhaust passage connecting portion can be covered by the guide member in a vehicle plan view and a vehicle front view. Thus, for example, in a state where the seat is lowered in a state where the seatback (backrest) of the seat is tilted forward, that is, in a state where the seat is lowered, the exhaust duct connection portion can be hidden from the passenger.
In addition, since the guide member is also covered with the carpet extending from the vehicle compartment side, the appearance of the vehicle compartment can be improved.
According to the aspect of the invention, the storage space for storing the power storage device can be partitioned from the vehicle interior without increasing the number of components and without securing an additional space.

The first seal 55 is provided on the upper surface 32a of the accommodating portion 32. The first seal 55 seals a gap between the upper surface 32a of the housing portion 32 and the passage cover 62. A second seal 76 is provided to the channel cover 62. The second seal 76 seals the gap between the passage cover 62 and the cover 61.
The third exhaust portion 44 opens into the storage space 29 (see fig. 11) of the luggage compartment tray 18. The third exhaust portion 44 is provided, for example, behind the guide member 64 and the support member 37 (see fig. 9), and opens forward.
As shown in fig. 1, the power storage device 20 is supported by a left rear frame 83 and a right rear frame 84 (both shown in fig. 10) via a left support bracket 81 and a right support bracket 82. In this state, the power storage device 20 is disposed in the storage space 29 of the luggage tray 18 (see fig. 11).
As shown in fig. 1, 3, and 4, power storage device 20 drives air-blowing fan 34 to take in air in vehicle interior 22 (see fig. 1) to air intake 41 as indicated by arrow a. The taken-in air is guided to the battery module 33, and exchanges heat with the battery module 33 (i.e., the battery cells 47). The air cooled by the heat exchange in battery module 33 is guided to first exhaust unit 42, second exhaust unit 43, and third exhaust unit 44 (see also fig. 6).
The air guided to the first exhaust portion 42 is guided to the first exhaust passage 73 through the first exhaust portion 42 as indicated by arrow B (see fig. 8). The air guided to the first exhaust duct 73 is discharged to the vehicle interior 22 as indicated by an arrow C via a part of the exhaust duct in the left side frame 12.
The air guided to the second exhaust portion 43 is guided to the second exhaust passage 74 through the second exhaust portion 43 as indicated by an arrow D (see fig. 9). The air guided to the second exhaust duct 74 is discharged to the vehicle interior 22 as indicated by arrow E via a part of the aforementioned exhaust duct in the right side frame 13.
On the other hand, the air guided to the third exhaust portion 44 is discharged to the storage space 29 (see fig. 11) of the luggage compartment tray 18 as indicated by an arrow F through the third exhaust portion 44.
As shown in fig. 3, 7, and 8, the guide member 64 is formed of a metal plate so as to cover the passage cover 62. The duct cover 62 made of resin is covered with the guide member 64 made of metal plate, so that the duct cover 62 can be protected by the guide member 64.
The guide member 64 has an upper guide portion 87 and a front guide portion 88. The upper guide portion 87 is fixed to, for example, the upper surface of the cover 61 (the upper surface of the cover portion 36) in a state of being disposed substantially horizontally so as to cover the upper surface 62a of the duct cover 62. The front guide portion 88 extends forward and downward from the front edge of the upper guide portion 87 (i.e., the upper surface of the power storage device 20) so as to cover the front surface 62b of the duct cover 62 (see also fig. 11). Thus, the guide member 64 overlaps the first exhaust part 42, the first exhaust passage 73, and the second exhaust part 43 in an overlapping state in a vehicle plan view and a vehicle front view.
As shown in fig. 9 to 11, the support member 37 is provided on the vehicle width direction side of the guide member 64. The support member 37 is provided so as to cover the DC power supply cable 71 from the front side, and is disposed in front of the plug cover 63 and the charging plug (not shown).
The support member 37 and the guide member 64 support the luggage room plate 16 disposed above the power storage device 20. Here, the support member 37 and the guide member 64 are disposed rearward of the bottom plate 14. A floor carpet 17 is laid on the floor panel 14 (see also fig. 1). The carpet 17 extends the portion 17a corresponding to the guide member 64 in the front-rear direction to the upper guide portion 87 rearward via the front guide portion 88 of the guide member 64.
The carpet 17 may extend rearward to the upper surface portion 37b via the front surface portion 37a of the support member 37, in addition to the portion 17a corresponding to the guide member 64 in the front-rear direction.
As described above, in the power storage device 20 according to the embodiment, as shown in fig. 7, 9, and 11, the upper guide portion 87 of the guide member 64 is disposed so as to cover the upper surface 62a of the duct cover 62. Further, the front guide portion 88 of the guide member 64 extends forward and downward from the front edge of the upper guide portion 87. Further, the guide member 64 is located rearward of the seat 15. The carpet 17 extends from the front of the guide member 64 to above the guide member 64 from the vehicle interior 22 side. The carpet 17 is laid so as to cover the floor panel 14 (see fig. 1).
Therefore, for example, in a state where the seat 15 is lowered and the front plate 16a of the luggage board 16 is lifted, the gap between the seat back 23 of the seat 15 and the guide member 64 of the power storage device 20 can be closed by the carpet 17.
Further, for example, the carpet 17 may be extended rearward to the upper surface portion 37b via the front surface portion 37a of the support member 37. In this case, even in a state where the front plate 16a of the luggage board 16 is lifted, the gap between the seat back 23 of the seat 15 and the support member 37 of the power storage device 20 can be closed by the carpet 17.
Thus, the storage space 29 for disposing (storing) the trunk board 18 of the electricity storage device 20 can be partitioned from the vehicle interior 22 by the carpet 17 without increasing the number of components and without securing an extra space. Therefore, it is possible to prevent an object from falling down to the luggage tray 18 without providing a conventional partition member.
As shown in fig. 3, 6, and 9, the third exhaust portion 44 opens forward. The third exhaust portion 44 is provided behind the guide member 64 and the support member 37. Further, the carpet 17 extends from the vehicle cabin 22 side to above the guide member 64. Further, the carpet 17 may be extended from the vehicle interior 22 side to above the support member 37.
Therefore, the carpet 17 is disposed in front of the third exhaust unit 44. This can prevent the exhaust air having a high temperature from directly flowing into the vehicle interior 22, and can suppress deterioration of the air conditioning comfort of the passenger. Further, the heat generated from power storage device 20 can be prevented from being transmitted to vehicle interior 22.
As shown in fig. 9 and 10, the support member 37 that supports the luggage room panel 16 is provided on the vehicle width direction side of the guide member 64. By connecting the support member 37 to the vehicle width direction side of the guide member 64, the exhaust air having a high temperature can be made less likely to flow into the vehicle interior 22, and the air conditioning comfort of the passenger can be further improved.
In addition, the support member 37 is provided in front of the plug cover 63. Therefore, it is not necessary to cover the plug cover 63 with the guide member 64 by passing the guide member 64 through the entire region of the power storage device 20 in the vehicle width direction. This allows the plug cover 63 to be removed to easily reach a charging plug (not shown) during maintenance and inspection, for example.
As shown in fig. 3, 7, and 8, the guide member 64 is fixed to the upper surface of the cover portion 36 (specifically, a part of the channel cover 62 and the cover 61). The guide member 64 is overlapped with the first exhaust portion 42 in an overlapping state in a vehicle plan view and a vehicle front view. Therefore, the guide member 64 can cover the first exhaust portion 42 in a vehicle plan view and a vehicle front view.
Thus, for example, in a state where the seat 15 is lowered and the front plate 16a of the luggage board 16 is raised, the first exhaust portion 42 can be hidden from the passenger.
As shown in fig. 9, a portion 17a of the carpet 17 corresponding to the guide member 64 extends rearward to the upper guide portion 87 via the front guide portion 88 of the guide member 64. This allows the guide member 64 to be covered with the portion 17a of the carpet 17, thereby improving the appearance of the vehicle interior 22.
The technical scope of the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the present invention.
In addition, the components in the above embodiments may be replaced with known components as appropriate within a range not departing from the gist of the present invention, and the above modifications may be combined as appropriate.
