The front cross member 20 is positioned behind the instrument panel 16 in the vehicle, and connects the pair of left and right side members 18, 18 in the vehicle width direction. The center cross member 21 is positioned behind the front cross member 20 across a floor panel 24 (described later) and connects the pair of left and right side members 18, 18 in the vehicle width direction (see fig. 8).
The Vehicle 10 of the present embodiment corresponds to a Hybrid Electric Vehicle (HEV) that runs using a motor unit and an engine (not shown) as drive sources, an Electric Vehicle that runs using only a motor unit (not shown) as a drive source, or the like.
An air conditioning unit 22 for cooling or heating the vehicle interior 14 is disposed on the instrument panel 16. The air conditioning unit 22 includes an electric pump, not shown, for supplying cold air or warm air into the vehicle interior 14 to cool or warm the vehicle interior 14.
As shown in fig. 1 and 2, a floor panel 24 constituting a lower portion of the vehicle interior 14 is disposed in the vehicle interior 14. A battery unit 26 having a box shape is provided on the floor panel 24. The battery unit 26 includes a bottomed case having a substantially rectangular opening on an upper surface thereof, and a cover for closing the opening of the case. In addition, the case and the cover may be integrally formed. The battery unit 26 is fastened and fixed to the floor panel 24 via screws, not shown. Between the air conditioning unit 22 and the battery unit 26 along the vehicle front-rear direction, a duct 28 that connects the air conditioning unit 22 and the battery unit 26 is provided. As shown in fig. 1, the battery unit 26 is disposed close to the front cross member 20 in the vehicle front-rear direction.
As shown in fig. 2, the floor panel 24 has a substantially rectangular shape in plan view, and includes a first concave portion 30 and a second concave portion 32. The battery cell 26 is housed in the first recess 30. The second recess 32 is formed in the bottom surface inside the first recess 30, and accommodates a part of the rear end side (distal end side) of the duct 28. Further, a center cross member 21 (see fig. 8) that connects the pair of left and right side members 18, 18 in the vehicle width direction is provided on the vehicle rear side of the first recess 30 of the floor panel 24.
The first recess 30 is formed by being recessed downward of the vehicle from the upper surface of the floor panel 24. The second recess 32 is formed to be recessed further toward the vehicle lower side from the bottom surface on the inner side of the first recess 30 (see fig. 6). Thus, the amount of depression of the second concave portion 32 that is depressed from the upper surface of the floor panel 24 toward the vehicle lower side is larger than the amount of depression of the first concave portion 30 that is depressed from the upper surface of the floor panel 24 toward the vehicle lower side. The area of the first recess 30 is larger than the area of the second recess 32 when the floor panel 24 is viewed from above. The second recess 32 is substantially L-shaped in plan view of the floor panel 24 (see fig. 2). The shape of the second recess 32 in a plan view is not limited to a substantially L shape, and may be freely set in a plan view so as to correspond to the shape of the pipe, such as a substantially T shape or a substantially H shape. As shown in the modification of fig. 9, when the second concave portions 32 and 32 are formed in a substantially H shape in plan view, they are configured to be divided in the vehicle front-rear direction.
A vehicle front end portion (open end portion) of the duct 28 is connected to one side of the air conditioning unit 22 in the vehicle width direction (see fig. 1). The vehicle rear end portion (terminal end portion) of the duct 28 is connected to the vehicle width direction center portion of the lower surface 26a of the battery unit 26 (see fig. 3).
Returning to fig. 1, the duct 28 is configured by integrally connecting a first portion 34a, an overtaking portion 34b, and a second portion 34c (see fig. 3). The first portion 34a extends rearward of the vehicle along the floor panel 24 from one side surface of the air conditioning unit 22 in the vehicle width direction, and then extends toward the other side surface in the vehicle width direction. The passing portion 34b is formed to be curved continuously with the end of the first portion 34a and to extend toward the vehicle rear side beyond the upper surface of the front cross member 20, and further extends toward the other side of the battery unit 26 in the vehicle width direction. The second portion 34c is continuous with the end of the over portion 34b, extends toward the vehicle width direction inner side of the battery unit 26 along the second recessed portion 32, and has an end extending to the center of the lower surface 26a of the battery unit 26 (see fig. 3). The second portion 34c has a substantially L-shape when the lower surface 26a of the battery cell 26 is viewed from an oblique direction.
The duct 28 has a fixing portion 36, and the fixing portion 36 can fix the lower surface 26a of the battery unit 26 before the battery unit 26 is mounted on the floor panel 24. As shown in fig. 5, the fixing portion 36 has a plurality of fixing claws 38 divided in the circumferential direction, and a slit, not shown, is provided between the adjacent fixing claws 38. The duct 28 is not limited to a structure connected before the battery unit 26 is installed on the floor panel 24. For example, the duct 28 may be fixed to the floor panel 24 side, and the battery unit 26 may be installed on the floor panel 24 while the duct 28 is inserted.
The fixing portion 36 is inserted into a substantially rectangular communication hole 57 (see fig. 4) formed in the lower surface of the temperature-adjusting plate 40 to be described later, and the claw portion 44 of the fixing claw 38 is elastically deformed toward the inner diameter side through a slit (not shown) to be inserted into the communication hole 57. After the fixing portion 36 of the duct 28 is inserted into the communication hole 57, the claw portion 44 at the tip end of the fixing claw 38 is locked to the upper surface of the temperature-adjusting tray 40 (lower wall 52b described later), whereby the fixing portion 36 of the duct 28 is fixed to the lower surface 26a of the battery cell 26. Further, a seal ring 46 for preventing air leakage is attached around the communication hole 57 between the temperature control panel 40 and the duct 28.
Here, the order of arranging the pipes 28 will be described.
First, the second portion 34c of the duct 28 is provided (connected) to the lower surface 26a of the battery unit 26. Next, the battery unit 26 is disposed in the first recess 30 of the floor panel 24 with the second portion 34c of the duct 28 connected. At this time, the second portion 34c of the duct 28 is disposed within the second recess 32 of the floor panel 24. Further, the second portion 34c of the duct 28 is connected to the passing portion 35b of the duct 28.
As shown in fig. 6, the battery unit 26 includes a pair of left and right batteries 48, and a temperature control panel 40 that is attached below each battery 48 and constitutes a temperature control path 50. As shown in fig. 3 and 4, the temperature-adjusting tray 40 includes an upper wall 52a positioned on the lower surface of each battery 48, a lower wall 52b spaced downward from the upper wall 52a by a predetermined distance, and a plurality of partition walls 54 connecting the upper wall 52a and the lower wall 52 b. The partition walls 54 are arranged side by side in the vehicle width direction and are disposed apart from each other by a predetermined interval in the vehicle front-rear direction.
Temperature control passages 50 (see fig. 6) through which temperature control air (cool air or warm air) supplied from the duct 28 flows to both sides in the vehicle width direction are provided between the upper wall 52a and the lower wall 52b of the temperature control panel 40 and between the adjacent partition walls 54, 54. A plurality of temperature control passages 50 are provided in parallel along the vehicle front-rear direction (see fig. 7). In fig. 7, six temperature control passages 50 are illustrated, but the present invention is not limited thereto. The length of both end portions of the lower wall 52b in the vehicle width direction is slightly shorter than the length of both end portions of the upper wall 52a in the vehicle width direction (see fig. 4). In the shortened portion, a partition wall 54 is provided so as to be visible from the bottom surface side.
The temperature-regulating disk 40 has a chamber 56 that connects the duct 28 in communication with the plurality of temperature-regulating passages 50. As shown in fig. 4, the chamber 56 extends in the vehicle longitudinal direction, and is formed by a plurality of cutout portions that are formed by cutting out the vehicle width direction center portions of the partition walls 54. Therefore, each partition wall 54 is formed by a partition wall 54a on one side (left side) in the vehicle width direction and a partition wall 54b on the other side (right side) in the vehicle width direction, which are divided.
A communication hole 57 (connection port of the duct 28) for communicating the passage in the duct 28 with the temperature control passage 50 of the temperature control panel 40 is provided in the center portion of the temperature control panel 40 (the lower wall 52b) in the vehicle width direction (see fig. 4 and 6). The communication hole 57 is formed in a rectangular shape that is long in the vehicle longitudinal direction when viewed from the bottom surface of the temperature adjustment dial 40 on the lower wall 52b side (see fig. 3 and 4). The temperature-adjusting air supplied from the duct 28 flows into the temperature-adjusting passage 50 through the communication hole 57 of the temperature-adjusting panel 40, and then flows out to both sides in the vehicle width direction through the chamber 56 and the temperature-adjusting passage 50.
As shown in fig. 6, a floor mat (floor carpet)58 is provided above the vehicle on the floor panel 24. A pair of left and right seats (automobile seats) 60, 60 are provided above the floor mat 58 in the vehicle width direction. The battery unit 26 is provided under the vehicle of the pair of right and left seats 60, 60. The floor mat 58 has a cut-out notch 62 under each seat 60. An end 64 of the cutout 62 on the vehicle width direction center side is provided on the vehicle width direction center side of the exhaust port 66 of the temperature control passage 50. The notch 62 is provided at one end and the other end in the vehicle width direction of the floor mat 58 at positions below the respective seats 60 that are not easily visible to passengers in the vehicle compartment 14.
As shown in fig. 6, the first recessed portion 30 has left and right side surfaces 30b rising from a bottom surface 30a of the first recessed portion 30 in the vehicle width direction. The temperature control passage 50 of the temperature control panel 40 has an exhaust port 66 facing each side surface 30b of the first recess 30.
The vehicle 10 to which the vehicle lower portion structure of the present embodiment is applied is basically configured as described above, and the operational effects thereof will be described below.
In the present embodiment, the vehicle rear end portion of the duct 28 is connected to the outer lower surface 26a of the battery unit 26. The floor panel 24 has a first recess 30 for accommodating the battery unit 26, and a second recess 32 formed in a bottom surface 30a inside the first recess 30 and for accommodating the duct 28.
In the present embodiment, the floor panel 24 is formed with two-step recesses including the first recess 30 and the second recess 32, and these serve as ribs, whereby the rigidity and strength of the floor panel 24 can be improved, and the mounting rigidity of the battery unit 26 can be improved. Therefore, in the present embodiment, the mountability of the battery unit 26 and the workability of connection between the battery unit 26 and the duct 28 can be improved. As a result, in the present embodiment, by securing three-dimensional spaces (the first recess 30 and the second recess 32) in the vehicle vertical direction, the rigidity of the cross member, the battery mountability, and the workability of connecting the battery unit 26 and the duct 28 can be secured, and the amount of battery mounting can be maximized.
In the present embodiment, the vehicle rear end portion (end portion) of the duct 28 is connected to the outer lower surface 26a of the battery unit 26, whereby the front cross member 20 and the battery unit 26 can be disposed close to each other in the vehicle front-rear direction. Further, in the present embodiment, since the battery unit 26 and the duct 28 can be provided only by changing the shape of the floor panel 24, more components such as the front cross member 20 can be shared with the vehicle on which the engine is mounted. As a result, in the present embodiment, the vehicle body of the electric vehicle mounted with the motor unit and the vehicle body of the vehicle mounted with the engine can be shared. In this regard, a vehicle that actually shares the front cross member 20 and the like is not assumed.
In the present embodiment, the duct 28 has a fixing portion 36 that can fix the lower surface 26a of the battery cell 26. Since the battery unit 26 can be fixed to the lower surface 26a of the battery unit 26 via the fixing portion 36, the battery unit 26 can be installed on the floor panel 24 with the duct 28 attached to the bottom surface of the floor panel 24 with respect to the battery unit 26. Thus, in the present embodiment, the battery unit 26 and the duct 28 can be mounted on the floor panel 24 with the duct 28 fixed to the battery unit 26 via the fixing portion 36. As a result, in the present embodiment, the mounting workability of the battery unit 26 and the duct 28 can be improved. In addition, in the present embodiment, since the battery unit 26 can be mounted while the duct 28 is guided by the second recess 32, the mounting workability can be further improved.
Further, in the present embodiment, the duct 28 is connected to the center portion of the lower surface 26a of the battery unit 26 in the vehicle width direction. The battery unit 26 has a temperature control passage 50 through which temperature-controlled air supplied from the duct 28 flows to both sides in the vehicle width direction. Thus, in the present embodiment, the temperature of the entire battery unit 26 can be uniformly adjusted (cooled or heated) by flowing the temperature-adjusting air supplied from the air conditioning unit 22 from the center of the battery unit 26 to both sides in the vehicle width direction.
In the present embodiment, the first recessed portion 30 has inner left and right side surfaces 30b, 30b rising from an inner bottom surface 30a of the first recessed portion 30 in the vehicle width direction. The temperature control passage 50 has exhaust ports 66 facing the inner side surfaces 30 b. Thus, in the present embodiment, the conditioned air passing through the temperature adjustment passage 50 can be made to contact the side wall (side surface 30b) of the first concave portion 30 to reduce the wind force, and therefore, the conditioned air can be prevented from being blown violently onto the passengers of the vehicle 10. In addition, in the present embodiment, an exhaust structure for discharging the conditioned air flowing along the temperature adjustment passage 50 to the outside of the vehicle is not necessary, and the vehicle body structure can be simplified.
In the present embodiment, a floor mat 58 is provided above the floor panel 24 in the vehicle. A seat 60 for an automobile is provided above the floor mat 58. The battery unit 26 is provided under the vehicle of the seat 60. The floor mat 58 has a cut-out notch 62 under the seat 60. An end 64 of the cutout 62 on the vehicle width direction center side is provided on the vehicle width direction center side of the exhaust port 66.
Thus, in the present embodiment, the cutout 62 is provided in the floor mat 58 under the seat 60 that is not easily visible to the passenger, thereby preventing interference with the battery unit 26 and a reduction in design (a reduction in appearance). In addition, in the present embodiment, the end portion 64 of the floor mat 58 suppresses the air-conditioned air flowing upward in the vehicle from the air outlet 66 along the side wall (side surface 30b) of the first recess 30, and thus the force of the air-conditioned air (influence on the passenger) can be further reduced.
In the present embodiment, the battery unit 26 includes the battery 48 and the temperature control panel 40 that is attached below the battery 48 and constitutes the temperature control path 50. The temperature control passages 50 are provided in plural in the vehicle front-rear direction. The temperature-adjusting disk 40 has a chamber 56 that connects the passage of the duct 28 in communication with the plurality of temperature-adjusting passages 50. Thus, in the present embodiment, the rigidity and strength of the temperature-adjusting tray 40 can be improved by providing a plurality of temperature-adjusting passages 50 in parallel in the vehicle longitudinal direction to have a honeycomb structure. In addition, in the present embodiment, since the conditioned air supplied from the duct 28 through the chamber 56 can be introduced into each temperature adjustment passage 50, the temperature of the battery 48 can be more uniformly adjusted.
