[Figure 8] Figure 8 is a perspective view of a modified conductive member 40A. [Modes for carrying out the invention]

[0011] Hereinafter, an embodiment of the conductive member and the mounting structure for the conductive member of the present invention will be described based on the attached drawings. The drawings should be viewed in the direction of the reference numerals.

[0012] First, with reference to Figures 1 and 2, the conductive member 40 of one embodiment of the present invention will be described.

[0013] FIG. 1 is a perspective view of the conductive member 40. FIG. 2 is a front view of the conductive member 40. In the description of FIGS. 1 and 2, the directions of the arrows shown in the figures will be described as the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively.

[0014] The conductive member 40 includes a flat conductive portion 41 and an insulating protective cover 50 that covers the outer peripheral surface of the conductive portion 41, and connects two electrical components. The two electrical components may be any components having terminal portions to which the conductive member 40 is connected. In an example described later, the two electrical components are two battery modules 11. Here, the conductive member 40 is arranged such that the longitudinal direction is the X-axis direction and the thickness direction is the Y-axis direction.

[0015] The conductive portion 41 is a bus bar formed of a conductive metal material. The conductive portion 41 is formed, for example, by pressing a sheet metal such as copper, iron, or aluminum. Further, the conductive portion 41 may be formed by pressing a sheet metal of an alloy such as a copper alloy or an aluminum alloy.

[0016] The conductive portion 41 has a main body portion 42 covered by the protective cover 50, and first and second connection portions 43a and 43b that are exposed from the protective cover 50 and are electrically connected to the terminal portions of the respective electrical components. Note that the main body portion 42 is covered by the protective cover 50 and is not visible, so it is shown by a broken line in the drawing.

[0017] The first connection portion 43a is provided at the +X side end portion 42a of the main body portion 42. The first connection portion 43a is provided so as to be bent toward the +Y side with respect to the main body portion 42. More specifically, the first connection portion 43a is provided by bending substantially at a right angle from the -Z side edge portion 42e1 of the main body portion 42 toward the +Y side. Here, the bent portion between the first connection portion 43a and the main body portion 42 is also referred to as a bent portion 44a. The bent portion 44a is provided on the -Z side with respect to the main body portion 42.

[0018] The second connecting portion 43b is provided at the -X side end 42b of the main body portion 42. The second connecting portion 43b is provided bent to the +Y side relative to the main body portion 42. More specifically, the second connecting portion 43b is provided bent at approximately a right angle to the +Y side from the +Z side edge 42e2 of the main body portion 42. Here, the bent portion between the second connecting portion 43b and the main body portion 42 is also called the bent portion 44b. The bent portion 44b is provided on the +Z side relative to the main body portion 42.

[0019] Both the first connecting portion 43a and the second connecting portion 43b have surfaces facing the Z-axis direction and are provided with through holes 45 that penetrate in the Z-axis direction. The first connecting portion 43a and the second connecting portion 43b are connected to an electrical component, for example, by inserting a stud bolt provided on the terminal portion of the electrical component through the through hole 45 and fastening it with a nut.

[0020] As described above, since the first connection portion 43a and the second connection portion 43b of the conductive portion 41 are bent relative to the main body portion 42, when the conductive member 40 is connected to an electrical component, the conductive member 40 does not protrude from the electrical component, making it easier to secure space around the electrical component. Therefore, the mounting of electrical components can be improved.

[0021] The protective cover 50 is made of an electrically insulating material such as synthetic resin. The protective cover 50 has a shape that conforms to the main body portion 42 of the conductive portion 41 and covers the main body portion 42.

[0022] The protective cover 50 has a first cover portion 51 that covers the main body portion 42 of the conductive portion 41 from the -Y side, and a second cover portion 52 that covers the main body portion 42 from the +Y side. The first cover portion 51 and the second cover portion 52 have recesses formed on the surfaces facing the main body portion 42, and the main body portion 42 is positioned in the space S partitioned by the recesses (see Figures 7(a) and 7(b)). The first cover portion 51 and the second cover portion 52 are provided with a plurality of retaining portions 53 on their peripheral edges, and the first cover portion 51 and the second cover portion 52 are fixed to each other at the retaining portions 53. The retaining portion 53 is composed of, for example, a claw portion and a hole portion that engages with the claw portion. In this way, the first cover portion 51 and the second cover portion 52 cover the main body portion 42 by sandwiching it from the thickness direction (Y axis direction) of the main body portion 42.

[0023] The protective cover 50 is provided with a first extension portion 55a and a second extension portion 55b extending from positions corresponding to the bent portions 44a and 44b of the conductive portion 41. The first extension portion 55a extends from the position corresponding to the bent portion 44a toward the -Z direction in the Z-axis direction. The second extension portion 55b extends from the position corresponding to the bent portion 44b toward the +Z direction in the Z-axis direction.

[0024] The first extension portion 55a and the second extension portion 55b have a plate shape that covers the first connecting portion 43a and the second connecting portion 43b, respectively, when viewed from the direction from the -Y side to the +Y side.

[0025] Since the protective cover 50 is provided with a first extension 55a and a second extension 55b, for example, when two electrical components and the conductive member 40 are connected, it is possible to avoid contact between the worker's fingers or tools and the first connection 43a and the second connection 43b, thereby ensuring safety. Furthermore, as described above, since the conductive member 40 has a first connection 43a and a second connection 43b that are bent relative to the main body 42, the mounting of electrical components to which the conductive member 40 is connected is improved, and as a result, both mounting and safety can be achieved.

[0026] The conductive member 40 has an inclined portion 47 between the first connecting portion 43a and the second connecting portion 43b. The inclined portion 47 is located in the central part of the conductive member 40 in the X-axis direction and is inclined so that it moves toward the -Z side as it moves toward the -X side.

[0027] The conductive member 40 has a point-symmetric shape with respect to a central axis C1 that passes through the center of the conductive portion 41. The central axis C1 is an axis that extends in the thickness direction (Y-axis direction) of the conductive member 40. Specifically, in Figure 2, when the conductive member 40 is rotated 180° around the central axis C1, the conductive member 40 after rotation and the conductive member 40 before rotation coincide. Therefore, when connecting the conductive member 40 to two electrical components, incorrect assembly can be avoided, and the ease of assembly of the conductive member 40 can be improved.

[0028] Furthermore, the main body portion 42 of the conductive portion 41 is provided with recesses 48 formed by bending at multiple locations. In the illustrated example, the recesses 48 are formed by bending four locations of the main body portion 42 and recessing them on the +Y side. Because the recesses 48 are provided, even if the two electrical components connected by the conductive member 40 are misaligned relative to each other, the tolerance is absorbed by the elastic deformation of the conductive member 40 in the recesses 48, thereby reducing the stress generated in the conductive portion 41.

[0029] Furthermore, at least in the recess 48, a gap is provided between the main body 42 and the protective cover 50. Specifically, the main body 42 is not tightly fitted into the space S within the protective cover 50, and a gap is provided between it and the protective cover 50 to allow for some deformation of the conductive part 41 in the space S. This prevents the protective cover 50 from being damaged by deformation of the conductive part 41.

[0030] Next, a mounting structure for a conductive member according to one embodiment of the present invention will be described. Specifically, a mounting structure in which the aforementioned conductive member 40 is attached to two electrical components will be described. Here, the case in which the conductive member 40 connects two battery modules 11 will be described as an example. First, a battery pack 10 comprising two battery modules 11 will be described.

[0031] Figure 3 is an exploded perspective view of a battery pack 10 mounted on a vehicle and equipped with a battery module 11. Figure 4 is a side view of the battery pack 10 with two battery modules 11 connected by a conductive member 40. The front of the vehicle on which the battery pack 10 is mounted is indicated as Fr, the rear as Rr, the left as L, the right as R, the top as U, and the bottom as D.

[0032] The battery pack 10 is installed in electric vehicles such as hybrid vehicles and battery-electric vehicles. The battery pack 10 stores electricity that is supplied to the motor and other power sources of the vehicle.

[0033] The battery pack 10 is mounted on the vehicle's floor panel 2. More specifically, the battery pack 10 is mounted in a recess 7 formed in the floor panel 2, with, for example, a cushioning material in between. A seat 3 (front seat or rear seat) is installed above the battery pack 10; that is, the battery pack 10 is located below the seat 3. The seat 3 is positioned on seat rails (not shown) suspended from a pair of front and rear cross members 5 and 6 of the vehicle body, which are located in front of and behind the battery pack 10.

[0034] The battery pack 10 comprises two battery modules 11 arranged side by side in the front-to-back direction, an ECU (Electronic Control Unit) 12 that controls the charging and discharging of the battery modules 11, a junction board 13 on which wiring components through which the charging and discharging currents of the battery modules 11 flow are mounted, a cooling mechanism 14 that cools the battery modules 11 with cooling air taken in from the vehicle interior, and a battery case 15 that houses these components.

[0035] The battery case 15 comprises a case body 16, which is a bottomed container with an open top, and a case cover 17 that covers the case body 16 from above. The case body 16 houses a battery module 11, an ECU 12, a junction board 13, and a cooling mechanism 14. The case cover 17 covers the case body 16 mounted on the floor panel 2 from above by fixing its front and rear ends to a pair of front and rear cross members 5 and 6. The case cover 17 is positioned at an angle to the rear and downward.

[0036] The two battery modules 11 are located on the left side of the case body 16. Each battery module 11 is constructed by stacking multiple battery cells and has a rectangular parallelepiped shape with its longitudinal direction running horizontally. Each battery cell is a secondary battery, such as a lithium-ion battery or a nickel-metal hydride battery.

[0037] The two battery modules 11 are fixed to the case body 16 by module brackets 18 provided on both the left and right sides. The two battery modules 11 have terminal portions 33 at their left ends, and conductive members 40 are connected to each terminal portion 33, thereby electrically connecting them to one another.

[0038] The ECU 12 is positioned above the battery module 11 via the ECU bracket 19. The junction board 13 is positioned on the right and front side of the case body 16.

[0039] The cooling mechanism 14 includes a fan 20 that draws in air from inside the vehicle and blows it to the battery module 11, an intake duct 21 connected to the intake port of the fan 20, and an exhaust duct 22 connected to the outlet port of the fan 20. The cooling mechanism 14 is an air-cooled cooling device that cools the battery module 11 with air.

[0040] The intake duct 21 connects the intake grille 25, located at the right end of the case cover 17, to the intake port of the fan 20. The blower duct 22 guides the air blown from the fan 20 to the battery module 11. The fan 20, intake duct 21, and blower duct 22 are positioned to the right of the battery module 11 in the case body 16.

[0041] Figure 5 is a perspective view of the conductive member 40 with the two battery modules 11 connected. Figure 6 is a top view of the conductive member 40 with the two battery modules 11 connected. Figure 7(a) is a cross-sectional view along line AA in Figure 6, and Figure 7(b) is a cross-sectional view along line BB.

[0042] Each battery module 11 includes a terminal block 31 having a terminal portion 33 to which the first connection portion 43a or second connection portion 43b of the conductive member 40 is connected, and a terminal cover 35 disposed on the terminal block 31 and covering the terminal portion 33 to which the first connection portion 43a or second connection portion 43b is connected. Note that the terminal cover 35 is omitted in Figure 5.

[0043] The terminal portion 33 is provided with an upward-extending stud bolt, and a through hole 45 formed in the first connection portion 43a or the second connection portion 43b of the conductive member 40 is inserted through the stud bolt and fastened with a nut (not shown). In the illustrated example, the first connection portion 43a of the conductive member 40 is connected to the terminal portion 33 (e.g., positive electrode) of the front battery module 11, and the second connection portion 43b of the conductive member 40 is connected to the terminal portion 33 (e.g., negative electrode) of the rear battery module 11.

[0044] The first connecting portion 43a is provided bent relative to the main body portion 42 such that the main body portion 42 is positioned above the first connecting portion 43a. The second connecting portion 43b is provided bent relative to the main body portion 42 such that the main body portion 42 is positioned below the second connecting portion 43b.

[0045] The terminal cover 35 is made of an electrically insulating material such as synthetic resin. The terminal cover 35 has a pivot shaft 36 that extends in the left-right direction. The pivot shaft 36 is provided at one end of the terminal cover 35 in the front-rear direction. The terminal cover 35 is rotatably mounted to the terminal block 31 by pivoting the pivot shaft 36 on a bearing 32 (see Figure 5) provided at the upper end of the terminal block 31. When connecting the conductive member 40 to the terminal portion 33, the terminal cover 35 opens the top of the terminal block 31, and after connecting the conductive member 40 to the terminal portion 33, it rotates to cover the top of the terminal block 31.

[0046] A slit 37 is provided between the terminal block 31 and the terminal cover 35, through which the first connection portion 43a and the second connection portion 43b of the conductive member 40 can be inserted. The main body portion 42 of the conductive member 40 is located on the outside of the terminal block 31, and the first connection portion 43a and the second connection portion 43b are connected to the terminal portion 33 of the terminal block 31 through the slit 37.

[0047] The first connection portion 43a is provided bent relative to the main body portion 42 so that the main body portion 42 is positioned above the first connection portion 43a, so the upper part of the slit 37 of the front battery module 11 is covered by the portion of the protective cover 50 that covers the main body portion 42. Similarly, the second connection portion 43b is provided bent relative to the main body portion 42 so that the main body portion 42 is positioned below the second connection portion 43b, so the lower part of the slit 37 of the rear battery module 11 is covered by the portion of the protective cover 50 that covers the main body portion 42. Thus, it is possible to avoid the worker's fingers or tools coming into contact with the first connection portion 43a and the second connection portion 43b.

[0048] The lower part of the slit 37 of the front battery module 11 and the upper part of the slit 37 of the rear battery module 11 are covered by the first extension 55a and the second extension 55b of the protective cover 50.

[0049] The first extension 55a and the second extension 55b of the protective cover 50 have a plate shape that covers the first connection portion 43a and the second connection portion 43b, respectively, and when the conductive member 40 is attached to the terminal portion 33 of the battery module 11, they cover the slit 37 when viewed from the left to the right.

[0050] More specifically, the first extension 55a extends downward from a position corresponding to the bent portion 44a between the first connection portion 43a and the main body portion 42, covering the lower part of the slit 37 of the front battery module 11. The second extension 55b extends upward from a position corresponding to the bent portion 44b between the second connection portion 43b and the main body portion 42, covering the upper part of the slit 37 of the rear battery module 11.

[0051] In this way, since the first extension portion 55a and the second extension portion 55b of the protective cover 50 cover the slit 37, it is possible to avoid the worker's fingers or tools coming into contact with the first connection portion 43a and the second connection portion 43b, thereby ensuring safety.

[0052] Furthermore, since the conductive member 40 has a first connection portion 43a and a second connection portion 43b that are bent relative to the main body portion 42, the left side of the battery module 11 to which the conductive member 40 is connected does not protrude, and space can be secured on the side of the battery module 11. As a result, the mounting of the battery module 11 to the case body 16 is improved, and as a result, both mounting and safety can be achieved.

[0053] The conductive member 40 has a point-symmetric shape with respect to the central axis C1 passing through the center of the conductive portion 41. Therefore, contrary to the illustration, the second connection portion 43b of the conductive member 40 can be connected to the front battery module 11, and the first connection portion 43a of the conductive member 40 can be connected to the rear battery module 11. In this way, incorrect assembly of the conductive member 40 can be avoided, and the ease of assembly of the conductive member 40 can be improved.

[0054] Furthermore, the conductive member 40 has an inclined portion 47 between the first connection portion 43a and the second connection portion 43b. Therefore, the space above the conductive member 40 can be widened in the inclined portion 47. In the battery pack 10 of this embodiment, as shown in Figure 4, the case cover 17 is provided at an angle that slopes downward to the rear, but since the conductive member 40 has an inclined portion 47, interference between the case cover 17 and the conductive member 40 can be avoided.

[0055] Furthermore, the recess 48 provided in the main body 42 of the conductive part 41 is formed to be recessed toward the space between the battery modules 11 which are arranged side by side. This allows for effective use of the space between the two battery modules 11.

[0056] (modified version) Figure 8 is a perspective view of a modified conductive member 40A. In the following description, components common to the conductive member 40 of the previously described embodiment may be referred to by the same reference numerals.

[0057] The conductive member 40A comprises a flat conductive portion 41 and an insulating protective cover 50 that covers the outer surface of the conductive portion 41, and connects two electrical components.

[0058] The conductive portion 41 of the conductive member 40A has the same basic configuration as the conductive portion 41 of the conductive member 40, but the configurations of the first connection portion 43a and the second connection portion 43b are different. Specifically, both the first connection portion 43a and the second connection portion 43b of the conductive member 40A are provided by bending approximately at a right angle from the -Z side edge portion 42e1 of the main body portion 42 toward the +Y side.

[0059] The protective cover 50 for the conductive member 40A has the same basic structure as the protective cover 50 for the conductive member 40, but the configuration of the first extension portion 55a and the second extension portion 55b are different. Specifically, the first extension portion 55a and the second extension portion 55b of the conductive member 40A both extend from positions corresponding to the bent portions 44a and 44b toward the -Z side in the Z-axis direction.

[0060] This configuration also ensures safety by preventing the worker's fingers or tools from coming into contact with the first connection portion 43a and the second connection portion 43b when the two electrical components and the conductive member 40A are connected. Furthermore, as mentioned above, since the conductive member 40A has the first connection portion 43a and the second connection portion 43b which are bent relative to the main body portion 42, the electrical components to which the conductive member 40A is connected are easily mounted, and as a result, both mountability and safety can be achieved.

[0061] Although one embodiment of the present invention and its variations have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to these embodiments. It is clear to those skilled in the art that various variations or modifications can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention. Furthermore, the components of the above embodiments may be combined in any way without departing from the spirit of the invention.

[0062] For example, in the embodiments and modifications described above, the conductive members 40 and 40A connect the terminal portions 33 of two battery modules 11 within the battery pack 10, but are not limited to this, and may connect electrical components other than the battery modules 11. For example, the conductive members 40 and 40A may connect the battery module 11 and the junction board 13. Furthermore, the conductive members 40 and 40A are not limited to connecting electrical components included in the vehicle's battery pack 10, but may connect any two electrical components. Also, the two electrical components are not limited to those mounted in the vehicle.

[0063] Furthermore, in the embodiments and modified examples described above, both the first connecting portion 43a and the second connecting portion 43b are provided bent relative to the main body portion 42, but a configuration in which only one of the connecting portions is provided bent relative to the main body portion 42 is also possible. In this case, the extension portion of the protective cover 50 should be provided at a position corresponding to the bent portion between the one connecting portion and the main body portion 42.

[0064] This specification includes at least the following: The components and other elements corresponding to those in the embodiments described above are shown in parentheses as examples, but are not limited thereto.

[0065] (1) A flat conductive part (conductive part 41) A conductive member (conductive member 40, 40A) that connects two electrical components (battery module 11), comprising an insulating protective cover (protective cover 50) that covers the outer circumferential surface of the conductive part, The conductive part is The main body (main body 42) is covered by the aforementioned protective cover, It has a first connection part (first connection part 43a) and a second connection part (second connection part 43b) that are exposed from the protective cover and electrically connected to the terminal parts (terminal parts 33) of each electrical component, At least one of the first and second connecting portions is provided bent relative to the main body portion.

Conductive material.

[0066] According to (1), since the connection portion of the conductive part is bent relative to the main body, the mounting of electrical components to which the conductive member is connected is improved. Furthermore, in a conductive member having such a bent connection portion, the protective cover is provided with an extension portion that extends from a position corresponding to the bend between the connection portion and the main body, so that the worker's hands or tools can not come into contact with the connection portion when the electrical component and the conductive member are connected. Thus, both mounting and safety can be achieved.
