    [001] This application claims priority to Japanese Patent Application No. 2010-130769, filed on June 8, 2010, the description of Japanese Patent Application No. 2010-130769 being incorporated herein in its entirety for reference. . Background Field of invention
    [002] The present invention relates, in general, to a carcass structure for vehicle batteries. More particularly, the present invention relates to a vehicle battery pack housing for an electric vehicle, hybrid vehicle, or other type of vehicle having components, such as an electric motor, powered by a battery. Background information
    [003] An electric or hybrid vehicle uses an electric motor as a source of energy to propel the vehicle. Therefore, such a vehicle typically includes a large-capacity battery pack as an electrical power source for the electric motor. A large-capacity battery pack typically includes several battery units that are electrically connected together to form a single battery pack. The battery pack, which can also be referred to as a battery module, is generally heavy and large in size. Therefore, when mounting such a battery pack in a vehicle, the battery pack must be mounted in order not to sacrifice the vehicle's internal space. Likewise, the mounting area on the vehicle must be configured to ensure that the size of the battery pack is not particularly limited, which would reduce the capacity of the battery. Likewise, the mounting area must be positioned to ensure that the vehicle's center of gravity is not raised to an undesirable degree.
    [004] A housing structure for a battery pack is described in Japanese Patent Application Open to Public Inspection No. 06-199183. The battery pack housing structure includes a space for the battery housing that is provided on a floor panel portion of the vehicle body directly below a seat attachment point. That is, in many vehicles, there is an unused dead space below the front seats, the rear seats, or both. The space for the battery housing is configured as an upward depression with a downward opening in the vertical direction of the vehicle body that houses the battery pack. Consequently, the battery pack can be housed in the dead space, and the capacity of the battery pack can be increased with little or no sacrifice of the vehicle's internal space. In addition, the space for the battery housing is provided below the vehicle's center of gravity, which lowers the vehicle's center of gravity and can increase the vehicle's stability. summary
    [005] However, Japanese Patent Application Open to Public Inspection No. 06- 199183 fails to describe a specific procedure for providing the space for the battery case as an upward depression opening downward in the vertical direction of the vehicle body in a floor panel of the vehicle body. Therefore, Japanese Patent Application Open to Public Inspection No. 06-199183 fails to solve problems such as those described below that can arise when a material is pulled up to form the floor panel of a vehicle body and the space for battery housing with opening downwards is formed in the floor panel.
    [006] For example, the elongation limit of the panel material limits the depth of the space for the battery housing. Therefore, when the panel material is drawn beyond the drawing depth, the panel material typically breaks at the intersection between the side walls of the battery housing space.
    [007] A certain degree of deep drawing can be achieved by increasing the bolting radius at the intersection between the side walls of the space for the battery housing, and providing an angle of exit angle to the side walls of the space for battery housing. However, in order to allow a deep drawing of a space for the battery housing to accommodate a large battery pack, the bolting radius at the intersection between the side walls and the angle of inclination of the side walls is increased to a greater degree. Therefore, the volume of the battery housing space is significantly reduced, which limits the size of the battery pack and sacrifices battery capacity.
    [008] Therefore, an objective of the present invention is to provide a carcass structure for a battery pack for a vehicle, such as an electric or hybrid vehicle, that can avoid the above problems.
    [009] In view of the state of the art technology, a carcass structure for vehicle battery packs basically includes a vehicle body panel, a first panel component, a second panel component and a third panel component. The first panel component is rigidly attached to the vehicle body panel, and the first panel component includes a first sidewall and a base wall. The second panel component is rigidly attached to the first panel component, and the second panel component includes a second side wall and a first peripheral wall portion. The third panel component is rigidly attached to the second panel component in such a way that the first, second and third panel components define a space for the battery housing that opens outwards. The third panel component includes a second peripheral wall portion that cooperates with the first peripheral wall portion to form a peripheral wall portion when the third panel component is rigidly attached to the second panel component.

    [021] The selected modalities will now be explained with reference to the drawings. It will be apparent to individuals skilled in the art from the description that the following descriptions of the modalities are provided by way of illustration only and not for the purpose of limiting the invention. as defined by the appended claims and their equivalents.
    [022] Referring initially to Figure 1, a carcass structure for a set of vehicle batteries is illustrated according to a first modality. Figure 1 is a perspective view from above on the left side of the vehicle, and shows the floor portion of the vehicle body that is provided with a carcass structure for a set of batteries according to an embodiment. The vehicle can be an electric vehicle, a hybrid vehicle or any type of vehicle having components, such as an electric motor, that are powered by a battery. Additionally, the vehicle can be a car, truck, van, sports utility vehicle (SUV) or any other suitable vehicle.
    [023] The floor portion of the vehicle body includes a floor portion of the vehicle body that includes a floor tunnel 1, a left sill 2L, a right sill 2R, a left floor panel 3L and a right floor panel 3R. Floor tunnel 1, left sill 2L, right sill 2R and other related floor components can be referred to individually or collectively as a vehicle body panel. The floor portion of the vehicle body also includes a plurality of cross members 4, 5, 6 and 7 provided in the left and right floor panels 3L and 3R. The cross members 4, 5, 6 and 7 extend in the width of the vehicle along the left and right floor panels 3L and 3R. A front seat 8 is attached to the cross members 4 and 5 as shown in Figure 2. A rear seat 9 is attached to the cross members 6, 7, also as shown in Figure 2. The cross members 4, 5, 6 and 7 can be attached to the left and right floor panels 3L and 3R in any suitable manner, such as by welds, bolts, screws, rivets, and so on. Additionally, the front seat 8 and the rear seat 9 can be attached to the left and right floor panels 3L and 3R and to the cross members 4, 5, 6 and 7 in any suitable way, such as by welds, bolts, screws, rivets , and so on.
    [024] In this example, the left and right floor panel portions 3L and 3R below the front seat 8 and the rear seat 9 are lowered upwardly in the vertical direction of the vehicle body (inwardly in the internal-external direction of the body) vehicle) in order to provide a space for battery housing with opening downwards or opening outwards 11, as shown in Figures 2 and 3. Naturally, however, the left and right floor panels 3L and 3R can configured to provide an opening in any suitable direction. A battery pack 12 including a plurality of battery units (not shown) as discussed earlier is housed in the battery housing space 11.
    [025] The front seat 8 and the rear seat 9 are fixed in a relatively high position inside the vehicle, as shown in Figure 2, for the desired seating level. As a result, an unused dead space is present below the front seat 8 and the rear seat 9. Therefore, in the present example, the corresponding portions of the left and right floor panels 3L and 3R are raised to a level directly below the front seat 8 and the rear seat 9 such that the space for the battery housing 11 directly below the attachment points of the front seat 8 and the rear seat 9 is deeper than the rest of the space for the battery housing 11, as shown in Figures 2 and 3. The vertical thicknesses of the battery pack 12 portions that are directly below the front seat 8 and the rear seat 9 can therefore be increased as shown in Figure 2. These increases in thickness can correspond to the degrees that the portions of the left and right floor panels 3L and 3R directly below seats 8 and 9 are raised in the manner previously described. Therefore, the thicknesses of the portions of the battery pack 12 can be equal or substantially equal to the distances that the portions of the left and right floor panels 3L and 3R directly under the seats are increased. Consequently, the dead space directly below the front seat 8 and the rear seat 9 can effectively accommodate an increased capacity of the battery pack 12 without sacrificing the vehicle's internal space.
    [026] However, when space for battery housing with opening down 11 is provided on the left and right floor panels 3L and 3R during a process of pulling a material to form the left and right floor panels 3L and 3R, the elongation limit of the panel material can be exceeded. Consequently, as discussed earlier, the panel material can break. Typically, the panel material can break at the intersection between the side walls of the battery housing space.
    [027] As also discussed earlier, the bolting radius at the intersection between the side parts of the battery housing space can be increased in order to reduce the occurrence of breaks. Likewise, an angle of exit angle can be provided to the side walls of the battery housing space in order to reduce the occurrence of breaks. However, in order to allow a deep drawing of the material to form a space for the carcass that is sufficient to accommodate a set of large and deep batteries, the bolting radius at the intersection between the side walls and the angle of inclination of the side walls is significantly increased. The larger bolting radius and the greater inclination angle can reduce the internal volume of the battery housing space, which limits the size and capacity of the battery pack.
    [028] Consequently, the following describes an example to provide the left and right floor panels 3L and 3R that can avoid the previous problems. It should also be noted that the configurations to provide space for battery housing 11 in relation to the left floor panel 3L and the right floor panel 3R are the same or similar to each other. Therefore, for example purposes, the configuration to provide space for battery housing 11 in relation to the left floor panel 3L will be described. The right floor panel 3R can be configured in the same or similar way, but as a mirror image of the left floor panel 3L.
    [029] Firstly, we describe the walls that define the space for the battery case with opening downwards 11. As shown, for example, in Figures 1 to 4, the space for the battery case 11 is defined by the side walls 13 and 14, by a base wall 15, and by an open peripheral wall 16. The side walls 13 and 14 extend along the downward opening. The base wall 15 is positioned to block the opening on the side away from the opening downwards. Likewise, the base wall 15 is divided by the side walls 13 and 14. The peripheral opening wall 16 extends in the peripheral direction of the opening downward from the side walls 13 and 14. The peripheral opening wall 16 is separated in the open peripheral wall portion 16a and 16b.
    [030] As shown in Figure 1 and in more detail in Figure 4, side walls 13 and 14 are separated in a line of intersection of side wall 17 in which side walls 13 and 14 intersect. In this example, the side wall 13 is integrally formed by the base wall 15 as part of a first panel component 18. In addition, the side wall 14 in this example is integrally formed by the opening peripheral wall portion 16b (first portion of peripheral wall) as part of a second panel component 19. The opening peripheral wall portion 16a (second peripheral wall portion) in this example is formed as part of a third panel component 20.
    [031] The walls defining the space for battery housing 13 to 16 are separated as previously described. Hence, the space for the battery housing with opening down 11 is defined by the first panel component 18 which includes the side wall 13 and the base wall 15, the second panel component 19 which includes the side wall 14 and the portion of opening peripheral wall 16b, and a third panel component 20 that includes opening peripheral wall portion 16a as shown in Figure 4. In this example, the space for downward opening battery housing 11 is provided on the left floor panel 3L assembling and joining the three components of panel 18 to 20.
    [032] That is, in this example, a flange 18a is present at the end of side wall 13 which is part of the first panel component 18. Flange 18a overlaps the third panel component 20, and therefore can overlap a portion of the opening peripheral wall portion 16a. Therefore, the flange 18a allows a gasket to be formed along the location where the panel components 18 and 20 are assembled and joined together.
    [033] In addition, a flange 19a is present in the opening peripheral wall portion 16b of the second panel component 19. The flange 19a overlaps the third panel component 20, and therefore overlaps a portion of the wall portion peripheral opening 16a. A flange 19b is present at an edge of the sidewall 14. Therefore, the flange 19b overlaps the sidewall 13 at the intersection line 17 of the sidewalls 13 and 14. A flange 19c is present along at least a portion of the sidewall 14. Consequently, flange 19c overlaps the base wall 15.
    [034] As indicated, flanges 18a, 19a, 19b and 19c provide seals between adjacent components that are assembled and joined together as discussed earlier. However, as shown in Figure 5, a corner span 21 may be present at a location or junction point where a corner of the first panel component 18, a corner of the second panel component 19 and the third panel component 20 are close to each other.
    [035] Corner span 21 can be sealed, for example, with a thermal expansion resin. The thermal expansion resin can be compacted in the corner gap 21 and expanded by heat during, for example, a coating step. Therefore, this seal can be achieved by a separate step of compacting the thermal expansion resin in the corner gap 21 and heating the thermal expansion resin. In addition, the thermal expansion resin can be expensive, which can increase the overall costs of the housing structure for the battery pack.
    [036] Therefore, in this example, a flange 22 that can be formed by bending can be used to seal the corner gap 21. That is, as shown in Figures 4 and 6, flange 22 can be formed to extend upwards from an inner peripheral region 20a of the third panel member 20, such as from the opening peripheral wall portion 16a, to overlap the side wall intersection line 17 at which the side walls 13 and 14 intersect . As shown in greater detail in Figures 6, 7 and 8, flange 22 includes an inclined flange portion 22a that extends at a predetermined slope θ from the inner peripheral region 20a of panel member 20 (for example, the from the opening peripheral wall portion 16a) towards the intersection line 17 of the side walls 13 and 14 in which an edge of the first side wall 13 and an edge of the second side wall 14 are positioned next to each other. The flange 22 further includes a vertical flange portion 22b that extends along the intersection line 17 of the side walls 13 and 14 from the distal end of the inclined flange portion 22a to a free end of the vertical flange portion 22b .
    [037] In the process for forming the flange 22, a projection to conform the flange 22 is provided to extend inwardly from the inner peripheral region 20a of the panel component 20, such as the opening peripheral wall portion 16a . This projection to conform the flange 22 can be molded by pressure, or the like, to form a structure that includes the inclined flange part 22a having the inclination angle θ, and a horizontal flange part 22c that extends in the horizontal direction from the distal end of the inclined flange part 22a, as shown in Figure 9. The horizontal direction can be parallel or substantially parallel to the panel component 20.
    [038] The horizontal flange part 22c described above is then raised in the direction of the arrow from the position of the double dashed line in Figure 8 corresponding to the state shown in Figure 9, to the position of the solid line. That is, a tool or other device can be used to apply a force against the horizontal flange part 22c to lift the horizontal flange part in the direction of the arrow shown in Figure 8. Consequently, the vertical flange part 22b is formed vertically from the distal end of the inclined flange part 22a, as shown in Figure 7. When the three components of the panel 18 to 20 are assembled and joined to provide space for the battery housing with opening down 11 to the panel left-hand floor 3L as previously described, the vertical flange part 22b extends along the intersection line 17 of the side walls 13 and 14, and is joined to the intersection line 17. The vertical flange part 22b can line the conjunction that is defined by the edges of the first and second side walls 13 and 14 and the inner peripheral region 20a of the third panel component 20. Therefore, the vertical flange part 22b can seal the v Corner section 21 shown in Figure 5 at the point of conjunction of the three panel components 18 to 20 by means of a cooperation with the inclined flange part 22a.
    [039] Again, as shown in Figure 7, the vertical flange part 22b is vertical from the distal end of the inclined flange part 22a that extends at a predetermined inclination θ in the third panel component 20 instead of being overturned. lime from the third panel component 20 as shown in Figure 10. Consequently, the height at which the flange is raised when molding the vertical flange part 22b can be small, as indicated by the height H1 in Figure 7, regardless - due to the required H2 height of the flange 22, which is used to seal the corner gap 21 shown in Figure 5.
    [040] The amount of tension at the distal end when lifting the flange of the vertical flange part 22b can therefore be reduced without considering the required H2 height of the flange 22. Likewise, it is possible to prevent the distal end of the vertical flange part 22b breaks during lifting of the flange which can compromise the sealing function of the flange 22. Consequently, the height of the vertical flange part 22b is configured in such a way that the distal end is not broken by exceeding if the tension limit of the panel material during the lifting of the flange, and the inclination angle θ of the inclined flange part 22a is adjusted in order to satisfy this configuration.
    [041] Furthermore, when an inclined flange part 22a, such as that provided in Figure 7, is not adjusted and the vertical flange part 22b is formed from the plane of the panel component 20, the height of the part vertical flange 22b is configured to be at least equal to the required height of the H2 flange indicated by the double dashed line as shown in Figure 10. However, when the vertical flange part 22b is high, the amount of tension at the distal end of the vertical flange part 22b during flange raising increases. Therefore, the distal end of the vertical flange part 22b may break during the lifting process, which can adversely affect the sealing function.
    [042] On the other hand, when measurements were taken to avoid such a rupture of the vertical flange part 22b, for example, by adjusting the bolting radius on the side wall intersection line 17 so that it is small, the bend radius of the vertical flange part 22b as indicated by R in Figure 7 may be small. In this configuration, the maximum height of the vertical flange part 22b is as low as H3 (= H1) as shown in Figure 10. Therefore, the height of the vertical flange part 22b would be generally insufficient in relation to the H2 flange height for seal the corner gap 21 as shown in Figure 5.
    [043] As can be seen from the above, the housing structure for the battery pack includes defining walls separate from the battery housing space 13 to 16 that define the space for the battery housing with opening downwards 11. The first panel component 18 includes the side wall 13 and the base wall 15. The second panel component 19 includes the side wall 14 and the peripheral opening wall portion 16b as shown in Figure 4. The third panel component 20 includes the opening peripheral wall portion 16a. Therefore, the space for battery housing with opening down 11 is defined by the first panel component 18, the second panel component 19 and the third panel component 20 which are assembled and joined by any suitable type of fixing member as discussed in this document.
    [044] Therefore, the space for battery housing with opening down 11 can be provided to the floor panel 3L without depending on the drawing of a material. Consequently, a deep and large space for battery housing 11 can be provided on the floor panel 3L without increasing the bolting radius at the side wall intersection line 17 of the space for battery housing with opening down 11, and without placing the side walls 13 and 14 of the battery housing space with downward opening 11 at an inclined angle. Consequently, the bolt radius at the side wall intersection line 17 of the battery housing space 11 can be as small as possible. In addition, the side walls 13 and 14 of the battery housing space 11 do not need to be tilted, and the side walls 13 and 14 can even be orthogonal or substantially orthogonal to the base wall 15. Therefore, the internal volume of the housing space of battery 11 need not be reduced to limit the size and capacity of the battery pack 12.
    [045] In addition, since the battery housing space 11 is configured as a downward opening battery housing space in which the 3L floor panel is lowered upwards in the vertical direction of the vehicle body, a dead space does not - used directly below seats 8 and 9 is effectively used. Therefore, the space for battery housing 11 can be expanded without sacrificing the internal space of the vehicle, and the capacity of battery pack 12 can be increased.
    [046] Likewise, flange 22 can seal the corner gap 21 which can be present in the place where the three components of the panel 18 to 20 meet without the use of a resin, for example, which can increase the complexity and the assembly costs of the three components of the panel 18 to 20 as previously discussed. This sealing by flange 22 can prevent or at least inhibit the penetration of water, or something like that, into the space for battery housing 11 through the corner gap 21.
    [047] Additionally, the walls defining the space for battery housing 13 to 16 do not need to be separated and then assembled as previously discussed. For example, side walls 13 and 14 can be integrally formed as a frame. The base wall 15 can be formed separately from the side walls 13 and 14. Likewise, the peripheral opening wall 16 can be a single integral component instead of being formed like the separate opening peripheral wall portions 16a and 16b. In addition, the peripheral opening wall 16 can be formed separately from the side walls 13 and 14. Alternatively, the walls 13 to 16 can be formed separate from each other or integral as desired. Therefore, the benefits discussed above can still be achieved by a housing structure for a battery pack in which the walls defining the space for battery housing 13 to 16 are separated or integral in this way.
    [048] In the understanding of the scope of the present invention, according to the use in question to describe the previous modality (s), the following directional terms “forward”, “backward”, “Above”, “down”, “vertical”, “horizontal”, “below” and “transverse” as well as any other similar directional terms refer to those directions of a vehicle equipped with the housing structure for the battery pack of electric vehicles. Consequently, these terms, as used to describe the present invention, must be interpreted in relation to a vehicle equipped with the carcass structure for an electric vehicle battery pack. Grade terms such as "substantially", "about" and "approximately" according to the usage in question mean a reasonable amount of deviation from the modified term, such that the final result is not significantly altered.
    [049] Although only the selected modalities have been chosen to illustrate the present invention, it will be apparent to individuals skilled in the art from this description that various changes and modifications can be made without departing from the scope of the invention as defined in the attached claims . For example, the size, format, location or orientation of the various components can be changed as needed and / or desired. The components that are shown directly connected or in contact with each other can have intermediate structures arranged between them. The functions of an element can be performed by two, and vice versa. The structures and functions of one modality can be adopted in another modality. It is not necessary that all the advantages are present in a particular modality at the same time. Each feature that is unique from the prior art, alone or in combination with other features, should also be considered as a separate description of other inventions by the applicant, including the structural and / or functional concepts incorporated by that feature (s) ). Therefore, the foregoing descriptions of the embodiments according to the present invention are provided by way of illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
