[0007] The battery pack support structure of the present invention, by having the configuration described in (1) above, can increase the strength of the cover. Therefore, the battery pack support structure of the present invention can suppress damage to the battery pack and electronic components in the event of a vehicle collision, etc. Furthermore, by having the configuration described in (1) above, the battery pack support structure of the present invention can suppress an increase in the size of the case in the height direction and reduce its weight. In addition, since the cover of the battery pack support structure of the present invention is divided into a cover part and a reinforcing part, the molding of the cover can be easily performed.

[0008] (2) In the battery pack support structure of the present invention, the case has a flange portion in which at least a part of the side wall forming a space for housing the electronic components is formed in a flat shape, the reinforcing portion has a flat portion that is flush with the flange portion, and fastening portions for fastening the electronic components are provided at a position adjacent to the flat portion.

[0009] The battery pack support structure of the present invention, by having the configuration described in (2) above, allows the flange portion and the flat portion to be in surface contact, thereby improving the strength of the fastening portion adjacent to the flat portion. Furthermore, in the battery pack support structure of the present invention, the flat surface between the flange portion and the flat portion may be used as a support surface for various members. This improves the fixation of various members in the battery pack support structure of the present invention.

[0010] (3) The battery pack support structure of the present invention is preferably characterized in that a sealing member is arranged to cover at least the outer circumference of the electronic component across the flat portion and the flange portion.

[0011] The battery pack support structure of the present invention ensures the waterproofness of electronic components by having the configuration described in (3) above. Furthermore, the battery pack support structure of the present invention can prevent warm air (heated air) exhausted into the vehicle interior for cooling the battery pack from entering the electronic components. Here, the sealing member is preferably arranged on a flat surface between the flange portion and the flat portion. This is expected to improve the sealing performance and ease of installation of the sealing member.

[0012] (4) The battery pack support structure of the present invention is characterized in that the electronic component is a blower for cooling the battery pack.

[0013] The battery pack support structure of the present invention, by having the configuration described in (4) above, allows the battery pack to be efficiently cooled by the blower. Furthermore, the battery pack support structure of the present invention can suppress the mixing of warm air into the cooling air exhausted from the blower, thereby improving the cooling efficiency of the blower.

[0014] (5) The battery pack support structure of the present invention is preferably characterized in that the cover portion and the reinforcing portion are joined by welding.

[0015] The battery pack support structure of the present invention can reduce the number of welding points by having the configuration described in (5) above.

[0016] (6) The battery pack support structure of the present invention is characterized in that the reinforcing portion constitutes the reinforcement of the vehicle.

[0017] The battery pack support structure of the present invention, by having the configuration described in (6) above, ensures the strength of the cover and case through the reinforcing portion. Here, it is desirable that the reinforcing portion be positioned on the exterior side of the vehicle. As a result, the battery pack support structure of the present invention can, for example, suppress damage to the battery pack, etc., by side collisions if the reinforcing portion is located on the side of the vehicle, and suppress damage to the battery pack, etc., by rear-end collisions if the reinforcing portion is located in the front-rear direction of the vehicle. [Effects of the Invention]

[0018] According to the present invention, it is possible to provide a battery pack support structure that can maintain strength while miniaturizing the case or cover for housing the battery pack.

Embodiment for Carrying out the Invention

[0020] Hereinafter, the battery pack support structure 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that each figure is schematically shown for easy understanding, and it should be noted that it may be different from the actual shape, size, and arrangement of components. Also, note that the hatching in the cross-sectional views of FIGS. 6 to 8 is omitted. Also, in the illustration, the left side in the vehicle width direction is referred to as the L side, the right side in the vehicle width direction is referred to as the R side, the front side in the vehicle longitudinal direction may be referred to as the Fr side, and the rear side in the vehicle longitudinal direction may be referred to as the Rr side.

[0021] As shown in FIGS. 1 to 4, the battery pack support structure 1 is configured to support a battery pack 2 and electronic components 3 (see FIGS. 3 and 4) on a vehicle frame 6 (also referred to as a vehicle frame 6; see FIG. 6(a)). The battery pack support structure 1 includes a case 10 that houses the battery pack 2 and the electronic components 3, a cover 20 attached to the case 10, and a pair of brackets 30, 30 fixed to the vehicle frame 6, etc.

[0022] Here, in this embodiment, the battery pack 2 is configured to constitute a driving battery mounted on an electric vehicle, a hybrid vehicle, or the like. The battery pack 2 is composed of, for example, an aggregate of a plurality of cells such as a lithium-ion battery or a nickel-metal hydride battery. In this embodiment, as shown in FIG. 4, a pair of battery packs 2, 2 formed in a rectangular shape are housed in parallel in the front-rear direction (Fr-Rr direction) of the case 10.

[0023] Furthermore, in this embodiment, as shown in Figures 3 and 4, the electronic component 3 is formed as, for example, a blower (hereinafter also referred to as blower 3). An exhaust duct 4 is connected to the blower 3. The blower 3 can exhaust air taken in from outside the case 10 through the exhaust duct 4 as cooling air for the battery pack 2. In addition, multiple flanges 3A for fixing the blower 3 are provided on the outer circumference of the blower 3.

[0024] The case 10 is formed in a roughly rectangular shape and includes a battery pack housing section 11 for housing a pair of battery packs 2,2, and an electronic component housing section 15 (also referred to as the blower housing section 15) for housing the blower 3. In this embodiment, the electronic component housing section 15 is integrally provided on the right side (R side) in the vehicle width direction of the battery pack housing section 11. The case 10 is formed, for example, by molding a metal plate-like member.

[0025] The battery pack housing 11 is formed in a substantially rectangular shape with its longitudinal direction aligned with the vehicle width. A pair of battery packs 2,2 are housed in the battery pack housing 11, parallel to each other in the vehicle's front-rear direction. The pair of battery packs 2,2 are supported by the battery pack housing 11 by fixing members 12 (see Figure 4). A partition wall 16a (side wall 16), described later, is erected between the battery pack housing 11 and the electronic component housing 15. The exhaust duct 4 of the blower 3 is connected to the partition wall 16a at the right (R) end of the battery pack housing 11. Therefore, cooling air from the blower 3 is introduced into the battery pack housing 11. A pair of support members 5,5 for fixing to the vehicle frame 6 (see Figure 6(a)) is provided on the left (L) side of the battery pack housing 11. A pair of brackets 30,30 constituting the battery pack support structure 1 of the present invention is provided on the right (R) side of the battery pack housing 11.

[0026] The electronic component housing section 15 is formed to accommodate the blower 3. The electronic component housing section 15 is formed in a substantially square shape in plan view, and is surrounded on all four sides by side walls 16 erected on the bottom surface of the case 10, thereby forming a space for housing the blower 3. As shown in Figure 4, the side wall 16 (also referred to as partition wall 16a) located between the electronic component housing section 15 and the battery pack housing section 11 separates the electronic component housing section 15 and the battery pack housing section 11. As shown in Figures 1 and 2, the upper side of the electronic component housing section 15 is covered by a blower duct cover 18. Part of the blower duct cover 18 opens toward the interior of the vehicle, allowing air from the interior of the vehicle to be taken in (see Figure 8). The blower duct cover 18 is attached to the electronic component housing section 15 (case 10) via a blower duct base 18a.

[0027] The partition wall 16a has a partial opening to which the exhaust duct 4 is connected. In other words, the electronic component housing 15 and the battery pack housing 11 are in communication via the exhaust duct 4. Therefore, the cooling air exhausted from the blower 3 is exhausted (blown) into the battery pack housing 11 via the exhaust duct 4.

[0028] As shown in Figures 3 and 4, each side wall 16 (including the partition wall 16a) is formed with a flange portion 17 by having at least a portion of its upper end flat. The flange portion 17 is designed to overlap flush with at least a portion of the flat portion 26 of the reinforcing portion 25, which will be described later. Furthermore, as shown in Figure 3, a sealing member 7 is provided on the upper surface of the flange portion 17 so as to surround the electronic component housing portion 15.

[0029] As shown in Figure 5, the cover 20 comprises a cover portion 21 and a reinforcing portion 25. In other words, the cover 20 is divided into a cover portion 21 and a reinforcing portion 25.

[0030] The cover portion 21 is formed from a roughly rectangular metal plate. As shown in Figures 1 to 3, the cover portion 21 covers at least a part of the battery packs 2,2. In this embodiment, the cover portion 21 covers almost the entire battery packs 2,2 except for a part on the left side (L side) in the vehicle width direction. Although not shown in the figures, a part of the L side of the battery packs 2,2 is covered by a separate cover member.

[0031] As shown in Figure 5, the reinforcing portion 25 is formed in a long, approximately rectangular shape in the vehicle's longitudinal direction (Fr-Rr direction). The reinforcing portion 25 is made of a metal plate (e.g., high-tensile steel) with higher strength than the cover portion 21. In other words, in this embodiment, the reinforcing portion 25 constitutes the vehicle's reinforcement. Therefore, the reinforcing portion 25 can suppress damage to the battery packs 2,2 in the event of a side collision with the vehicle. As shown in Figures 1 to 4, a portion of the reinforcing portion 25 on the left side (L side) in the vehicle width direction is formed in a shape that can overlap with the cover portion 21. As shown in Figure 6(b), the reinforcing portion 25 and the cover portion 21 are joined and integrated by welding (e.g., spot welding at multiple points along the vehicle's longitudinal direction) in the overlapping portion (within the circle of the dashed line). Also, as shown in Figures 3 and 4, the reinforcing portion 25 has a flat portion 26 on the right side (R side) in the vehicle width direction that is flush with the flange portion 17. The reinforcing section 25 is provided with a pair of fastening sections 28, 28 located adjacent to the flat section 26. The reinforcing section 25 is also provided with holes 27, 27 at both ends in the front-rear direction for attaching brackets 30, 30 with bolts or the like (see Figures 4 and 5).

[0032] The fastening portions 28, 28 are positioned below the flat portion 26, and their upper surfaces are formed flat. The blower 3 can be fixed by fastening the fastening portions 28, 28 with bolts (not shown) or the like when the flanges 3A, 3A of the blower 3 are placed on top of each other. As a result, the blower 3 is fixed to the blower housing 15 via the fastening portions 28, and the reinforcing portion 25 is fixed to the blower housing 15.

[0033] The sealing member 7 is positioned across the flat portion and flange portion 17 of the reinforcing portion 25, and covers the outer circumference of the blower 3. As shown in Figure 3, the sealing member 7 is formed of an annular rubber material or the like in a roughly rectangular shape, surrounding the electronic component housing portion 15. As shown in Figures 7 and 8, the sealing member 7 can prevent water and the like from entering the blower 3 from below the floor surface (carpet surface) inside the vehicle. In addition, the sealing member 7 can prevent the cooling air (warm air) used to cool the battery packs 2,2 from leaking out near the opening on the vehicle side of the blower 3 (see Figure 8). As a result, the battery pack support structure 1 can improve the cooling efficiency of the battery packs 2,2.

[0034] As shown in Figure 5, the brackets 30, 30 are formed, for example, by bending a metal plate-like member into an L-shape. In this embodiment, a pair of brackets 30, 30 are arranged on both sides of the reinforcing portion 25 in the front-rear direction (Fr-Rr direction). The brackets 30, 30 can be fastened with bolts or the like to the side wall portions 13, 13 (see Figure 4) that are erected in the front-rear direction of the case 10 (battery pack housing portion 11). When supported by the case 10, the brackets 30, 30 have protruding portions 31, 31 that project outward from the case 10.

[0035] Each of the protruding portions 31, 31 has a hole 32 through which a bolt is inserted. The protruding portions 31, 31 are connected to and fixed to the reinforcing portion 25 by inserting a bolt (not shown) through the holes 27, 27 and through the holes 32, 32 with the reinforcing portion 25 superimposed on the upper side and fastening it. In this way, the cover 20 is fixed to the case 10 via the brackets 30, 30 (see Figures 1 to 3).

[0036] Furthermore, as shown in Figure 6(a), fixing holes 33 for fixing to the vehicle frame 6 are formed on the protruding ends of the protruding portions 31, 31. The protruding portions 31, 31 can be fixed to the vehicle frame 6 by, for example, overlapping them with the vehicle frame 6 from above and fastening them by inserting bolts (not shown) through the fixing holes 33. In this way, the case 10 is fixed to the vehicle frame 6 via the brackets 30, 30.

[0037] The above describes one embodiment of the battery pack support structure 1 of the present invention. Next, the effects and advantages realized by the battery pack support structure 1 of the present invention will be described below.

[0038] <Effects> The battery pack support structure 1 described above has the following characteristic configurations (a) to (f). Therefore, the battery pack support structure 1 of the present invention can achieve the following unique effects that cannot be achieved with the prior art.

In addition, since the cover 20 of the battery pack support structure 1 of the present invention is divided into a cover portion 21 and a reinforcing portion 25, the molding of the cover 20 can be easily performed.

[0041] (b) In the battery pack support structure 1 of the present invention, the case 10 has a flange portion 17 formed in a flat shape, at least a part of which of the side wall 16 that forms a space for housing the electronic components 3 is flat, and the reinforcing portion 25 has a flat portion 26 that is flush with the flange portion 17, and a fastening portion 28 for fastening the electronic components 3 is provided at a position adjacent to the flat portion 26.

Furthermore, in the battery pack support structure 1 of the present invention, the flat surface between the flange portion 17 and the flat portion 26 may be used as a support surface for various members. This improves the fixation of various members in the battery pack support structure 1 of the present invention.

[0043] (c) The battery pack support structure 1 of the present invention is characterized in that a sealing member 7 is arranged to cover at least the outer circumference of the electronic component 3 across the flat portion 26 and the flange portion 17.

[0044] The battery pack support structure 1 of the present invention, by having the configuration described in (c) above, ensures the waterproofness of the electronic component 3. Furthermore, the battery pack support structure 1 of the present invention is used to cool the battery pack 2 and can suppress the intrusion of warm air exhausted into the vehicle interior into the electronic component 3. Here, the sealing member 7 is preferably arranged on a flat surface between the flange portion 17 and the flat portion 26. This is expected to improve the sealing performance of the sealing member 7 and improve the ease of installation of the sealing member 7.

[0045] (d) The battery pack support structure 1 of the present invention is characterized in that the electronic component 3 is a blower 3 that cools the battery pack 2.

[0046] The battery pack support structure 1 of the present invention, by having the configuration described in (d) above, can efficiently cool the battery pack 2 with the blower 3. Furthermore, the battery pack support structure 1 of the present invention can suppress the mixing of warm air into the cooling air exhausted from the blower 3, thereby improving the cooling efficiency of the blower 3.

[0047] (e) The battery pack support structure 1 of the present invention is characterized in that the cover portion 21 and the reinforcing portion 25 are joined by welding.

[0050] The battery pack support structure 1 of the present invention, by having the configuration described in (f) above, ensures the strength of the cover portion 21 and the case 10 through the reinforcing portion 25. Here, it is desirable that the reinforcing portion 25 be positioned on the outside side of the vehicle. As a result, the battery pack support structure 1 of the present invention can, for example, suppress damage to the battery pack 2 etc. due to side impacts if the reinforcing portion 25 is located on the side of the vehicle, and suppress damage to the battery pack 2 etc. due to rear-end collisions if the reinforcing portion 25 is located in the front-rear direction of the vehicle.

[0051] ≪Variations≫ The above describes the effects and advantages obtained by the battery pack support structure 1 according to one embodiment of the present invention. However, the battery pack support structure 1 is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. For example, the battery pack support structure 1 may be as described in (a) above, and can be formed in various shapes and sizes. For example, the shape, size, and material of the case 10 and cover 20 can be changed to various types depending on the shape, size, and configuration of the battery pack 2 and the electronic component 3. In addition, the battery pack 2 supported by the battery pack support structure 1 can be of various configurations, shapes, sizes, and quantities. Furthermore, the cover portion 21 and the reinforcing portion 25 can be arranged in various ways depending on the placement of the battery pack support structure 1 in the vehicle and the placement position of the battery pack 2. In addition, the battery pack support structure 1 of the present invention may, for example, not include some or all of the configurations described in (b) to (f) above, or may include some or all of the configurations described in (b) to (f) above, and other configurations.

[0052] In this embodiment, the configuration is as shown in (b) above, but the arrangement of the flange portion 17, the flat portion 26, and the fastening portion 28 is not limited to the embodiment described above, and various arrangements can be made depending on the shape and size of the case 10 and the reinforcing portion 25. Furthermore, the flange portion 17, the flat portion 26, and the fastening portion 28 do not necessarily have to be formed in a flat shape, and they may be configured to be overlapping in shape and size depending on the shape and size of each other.

[0053] In this embodiment, a sealing member 7 is arranged to cover the outer circumference of the blower 3 across the flat portion 26 and the flange portion 17, but the present invention is not limited to this. The sealing member 7 may be provided as needed, and a configuration without a sealing member 7 is also possible. In the case of a configuration without a sealing member 7, for example, the boundary portion between the blower housing 15 (electronic component housing 15) and the cover 20 may be made into an intricate structure with irregularities. Furthermore, the sealing member 7 can be made of various materials, shapes, and sizes. In addition, the sealing member 7 can be arranged in various ways. Here, it is desirable to determine the arrangement of the sealing member 7 considering the need to make it difficult for heated air to be drawn back into the blower 3 and to suppress water ingress into the blower 3.

[0054] In this embodiment, a blower 3 for cooling the battery pack 2 is used as the electronic component 3, but the present invention is not limited to this and can be applied to various electronic components 3. For example, the electronic component 3 may be a BCU (Battery Control Unit). Furthermore, the electronic component 3 may consist not only of a single component but also of a combination of multiple components (for example, a combination of a BCU and a blower 3).

[0055] In this embodiment, the cover portion 21 and the reinforcing portion 25 are joined by welding. However, the joining of the cover portion 21 and the reinforcing portion 25 is not limited to welding, and various joining methods (e.g., adhesive bonding) can be used. Furthermore, when joining the cover portion 21 and the reinforcing portion 25 by welding, various welding methods other than spot welding can be used.

[0056] In this embodiment, the reinforcing portion 25 is made of high-tensile steel and constitutes the vehicle's reinforcement, but the present invention is not limited to this. For example, the reinforcing portion 25 may be made of a combination of steel materials other than high-tensile steel. Alternatively, the reinforcing portion 25 may be made of fiber-reinforced resin such as CFRP. In such cases, the reinforcing portion 25 and the cover portion 21 may be fixed by adhesive or the like instead of welding. The cover portion 21 may also be made of various steel plates, fiber-reinforced resin, etc.

[0057] The above describes various embodiments and modifications of the battery pack support structure according to the present invention. However, the present invention is not limited to those exemplified in the embodiments and modifications described above, and it will be readily apparent to those skilled in the art that other embodiments may exist in the spirit and nature of the teachings, without departing from the scope of the claims.
