[0043] FIG. 1 shows a perspective view of a base frame (10) of a bracket assembly according to one embodiment of the present invention. FIG. 2 shows a cross-sectional view of a base frame (10) of a bracket assembly according to one embodiment of the present invention.

[0044] Referring to FIGS. 1 and 2, the base frame may have the form of a beam extending along the longitudinal direction. The base frame may be formed as a rigid body having a predetermined strength and may be provided to support a secondary battery module or a secondary battery pack. The base frame may be formed by including a metal material, such as steel, or an alloy material having high rigidity to support a load, for example. A secondary battery structure, such as a battery pack, may be supported by being seated on the upper surface of the base frame (10). On the upper surface of the base frame (10), coupling elements (13) for coupling with the secondary battery structure or an external frame may be formed. The coupling elements (13) may have the form of a screw hole into which a screw bolt can be coupled, for example, but are not limited thereto.

[0045] A recess (11) may be formed in the base frame (10). The recess (11) may have a shape that is recessed inwardly into the base frame (10) and may be formed in multiple numbers. For example, the recess (11) may have a shape that extends along the length direction of the base frame (10). The recess (11) may be formed in pairs. In this case, the base frame (10) may be provided as an H-beam with an H-shaped cross-section perpendicular to the length direction. A support bracket (20) may be received / coupled in the receiving space (12) of the recess (11).

[0046] The recess (11) may have a first surface (101) and a second surface (102). The first surface may be a surface formed along the longitudinal direction of the base frame (10). The first surface may constitute the inner surface of the recess (11). The second surface (102) may be a surface spaced apart parallel to the first surface (101). The second surface (102) may face the first surface (101). The second surface (102) may form the inner surface of the recess (11) together with the first surface (101). The first surface (101) and the second surface (102) may be spaced apart from each other by a predetermined distance (120). The recess (11) may be formed with a predetermined depth (110). The distance (120) between the first surface (101) and the second surface (102) and the depth (110) of the depression (11) can define the size of the receiving space (12) of the depression (11).

[0047] FIG. 3 is a perspective view showing a support bracket (20) of a bracket assembly according to one embodiment of the present invention.

[0048] Referring to FIG. 3, a support bracket (20) of a bracket assembly according to one embodiment of the present invention may be provided to be coupled to a base frame (10). The support bracket (20) may be provided to reinforce the structural stability of the base frame (10) while coupled to the base frame (10). The support bracket (20) may be provided to be detachably attached to a recess (11) of the base frame (10). The support bracket (20) may have an L-shape or a rectangular shape, but is not limited thereto. The support bracket (20) may be formed from a steel or aluminum alloy material, like the base frame (10).

[0049] The support bracket (20) may be coupled to the recess (11) so as to be received in the recess (11) of the base frame (10), or may be coupled to the recess (11) in a form such that at least one part protrudes outside the recess (11). In other words, the support bracket (20) may be coupled to the recess (11) in different forms.

[0050] Specifically, the support bracket (20) can be combined in a form that is completely received in the receiving space (12) of the recess (11) (hereinafter referred to as the receiving state), and in this case, the overall volume of the bracket assembly according to the present invention can be reduced. Accordingly, the transportation and packaging processes of the bracket assembly can be carried out more efficiently, and furthermore, the possibility of damage to the support bracket (20) that may occur during transportation can also be significantly reduced. The receiving state of the support bracket (20) will be described in more detail in FIGS. 4 to 6, which will be described later.

[0051] In contrast, the support bracket (20) may be coupled to the recess (11) in a form in which at least one part protrudes outside the recess (11) (hereinafter, installed state), and in this case, the support bracket (20) can distribute the load of the bracket assembly in a form that supports the base frame (10). The installed state of the support bracket (20) will be described in more detail in FIGS. 7 to 9, which will be described later.

[0052] The support bracket (20) may include a first connecting plate (21). The support bracket (20) may further include a second connecting plate (22).

[0053] The first connecting plate (21) may overlap the bottom surface (109) of the recess (11) in the storage state of the support bracket (20). The bottom surface (109) may be a surface perpendicular to the depth (110) direction of the recess (11), and may be a surface perpendicular to both the first surface (101) and the second surface (102).

[0054] The first coupling plate (21) may be provided in the form of a rectangular flat plate having a predetermined thickness and may form the length (230) and width (220) of the support bracket (20). The length (230) of the support bracket (20) may be greater than the width (220) of the support bracket (20). The first coupling plate (21) may be provided with a plurality of holes that function as coupling elements. A first hole (26) and a second hole (27) may be formed through the first coupling plate (21). The first hole (26) and the second hole (27) may be screw holes with threads formed therein for screw coupling, for example.

[0055] The first hole (26) may be a hole provided so that the support bracket (20) is coupled with the recess (11). The first hole (26) may be provided so that it is coupled with the bottom surface of the recess (11) when the support bracket (20) is in a recessed state. The first hole (26) may be provided in multiple numbers. For example, a pair of first holes (26) may be provided spaced apart in the width (220) direction of the support bracket (20).

[0056] The second hole (27) may be a hole provided to be connected to an external structure when the support bracket (20) is installed. The second hole (27) may be provided to be connected to a support structure or the ground on which the base frame (10) is placed when the support bracket (20) is installed. The second hole (27) may have a larger diameter than the first hole (26) to transmit a solid support force to the base frame (10). The second hole (27) may be spaced apart from the first hole (26) in the length (230) direction of the support bracket (20). The distance between the second hole (27) and the second connecting plate (22) may be greater than the distance between the first hole (26) and the second connecting plate (22).

[0057] A second connecting plate (22) may be provided at the longitudinal end of the first connecting plate (21). The second connecting plate (22) may form the height (210) of the support bracket (20). The second connecting plate (22) may extend from the longitudinal end of the first connecting plate (21) in the direction of the height (210) of the support bracket (20).

[0058] At least one hole that functions as a coupling element may be formed through the second coupling plate (22). A third hole (28) may be formed through the second coupling plate (22), and a plurality of third holes (28) may be provided spaced apart from each other. For example, a pair of third holes (28) may be provided spaced apart in the width (220) direction of the support bracket (20). At least one of the pair of third holes (28) may be a screw hole with threads formed for screw connection.

[0059] The third hole (28) can be joined by overlapping with the bottom surface (109) of the recess (11) in the installed state of the support bracket (20). The third hole (28) may have the same diameter as the first hole (26) formed in the first connecting plate (21).

[0060] The support bracket (20) may further include side plates (23). The side plates (23) may be provided in pairs and spaced apart from each other in the width (220) direction of the support bracket (20). The side plates (23) may be connected to the ends in the width (220) direction of the first connecting plate (21) and the second connecting plate (22) to reinforce the support force of the first connecting plate (21) and the second connecting plate (22) and increase the rigidity.

[0061] FIGS. 4 to 6 illustrate the storage state of a bracket assembly according to an embodiment of the present invention. Specifically, FIG. 4 is a perspective view illustrating the storage state of a bracket assembly according to an embodiment of the present invention. FIG. 5 shows a front view of the storage state of a bracket assembly according to an embodiment of the present invention. FIG. 6 shows a side view of the storage state of a bracket assembly according to an embodiment of the present invention.

[0062] Referring to FIGS. 4 to 6, a support bracket (20) of a bracket assembly according to one embodiment of the present invention can be fully received in a recess (11) of a base frame (10). In this case, the support bracket (20) can be positioned in a receiving space (12) of the recess (11), and the support bracket (20) may not protrude outside the receiving space (12). To this end, the height (210) of the support bracket (20) may be smaller than the depth (110) of the recess (11). The width (220) of the support bracket (20) may be smaller than the distance (120) between the first surface (101) and the second surface (102) of the recess (11). In the receiving state, the length (230) direction of the support bracket (20) may coincide with the length direction of the base frame (10). The first connecting plate (21) of the support bracket (20) can overlap with the bottom surface (109) of the recess (11).

[0063] In the storage state of the support bracket (20), the remaining portion of the support bracket (20), excluding the first connecting plate (21), may be maintained at a predetermined distance from the inner surface of the recess (11). For example, the side plate (23) of the support bracket (20) may be maintained at a distance from the first surface (101) and the second surface (102) of the recess (11).

[0064] Alternatively, the side plate (23) of the support bracket (20) may be supported by contacting the inner surface of the recess (11). For example, one of the pair of side plates (23) of the support bracket (20) may be supported in the direction of gravity by contacting the second surface (102), and in this case, the structural stability of the support bracket (20) in the storage state may be improved.

[0065] A guide projection (15) may protrude to a predetermined height from the bottom surface (109) of the recess (11). In the storage state, the guide projection (15) may be inserted into one of a pair of first holes (26) formed in the first coupling plate (21) of the support bracket (20). The diameter of the guide projection (15) may be smaller than the size of the first hole (26) formed in the first coupling plate (21), and by engaging the guide projection (15) with one first hole (26), the connection between the other first hole (26) and the bottom surface (109) of the recess (11) may be made easier. A first coupling hole (16) may be formed through the bottom surface (109) of the recess (11) at a position corresponding to the other first hole (26) of the first coupling plate (21). The first coupling hole (16) can be formed through the guide projection (15) in the width direction of the recess (11), that is, in the direction of the distance (120) between the first surface (101) and the second surface (102). The distance between the guide projection (15) and the first coupling hole (16) can be the same as the distance between a pair of first holes (26) of the first coupling plate (21) of the support bracket (20).

[0066] The first coupling hole (16) formed on the bottom surface (109) of the recess (11) and the other first hole (26) formed on the first coupling plate (21) of the support bracket (20) can be coupled with screws, etc., while aligned at corresponding positions. Here, either the first hole (26) or the first coupling hole (16) is formed with a diameter larger than the other by a predetermined range, thereby solving the problem where the two holes (26, 16) do not overlap when aligned by the coupling of the guide projection (15) or when the support bracket (20) is supported on the second surface (102) in the direction of gravity, making it difficult to combine with screws, etc., thus improving the convenience of coupling or assembly.

[0067] FIGS. 7 to 9 illustrate the installation state of a bracket assembly according to an embodiment of the present invention. Specifically, FIG. 7 is a perspective view illustrating the installation state of a bracket assembly according to an embodiment of the present invention. FIG. 8 shows a front view of the installation state of a bracket assembly according to an embodiment of the present invention. FIG. 9 shows a side view of the installation state of a bracket assembly according to an embodiment of the present invention.

[0068] Referring to FIGS. 7 to 9, a support bracket (20) of a bracket assembly according to one embodiment of the present invention may be coupled in an installed state to a recess (11) of a base frame (10). In the installed state, a portion of the support bracket (20) may protrude outside the receiving space (12) of the recess (11). The protruding portion of the support bracket (20) protruding outside the receiving space (12) of the recess (11) may be supported by a lower structure together with the bottom surface of the base frame (10). That is, the protruding portion of the support bracket (20) may be provided to reinforce the structural rigidity of the base frame (10).

[0069] The length (230) of the support bracket (20) may be greater than the depth (110) of the recess (11) so that the support bracket (20) protrudes from the receiving space (12) of the recess (11). Additionally, the height (210) of the support bracket (20) may be smaller than the distance (120) between the first surface (101) and the second surface (102) of the recess (11). In the installed state, the width (220) of the support bracket (20) does not have any separate structural limitations, but as described above, it may be smaller than the distance (120) between the first surface (101) and the second surface (102) so that the support bracket (20) can be converted to a receiving state.

[0070] In the installed state, the second connecting plate (22) of the support bracket (20) can be connected by overlapping with the bottom surface (109) of the recess (11). The first connecting plate (21) of the support bracket (20) can be connected to the second surface (102) of the recess (11). At this time, a portion of the first connecting plate (21) may be in a state where it protrudes outside the recess (11).

[0071] The second hole (27) of the first connecting plate (21) may be positioned so as to protrude outside the recess (11). The second hole (27) protruding outside the recess (11) may have the largest diameter among the plurality of holes formed in the supporting bracket (20) to form a connection with the lower structure or ground on which the supporting bracket (20) and base frame (10) are seated in the installed state.

[0072] The support bracket (20) may further include a bottom frame (24) provided so that the height of the bottom surface matches that of the base frame (10). The bottom frame (24) may ensure that the height of the bottom of the support bracket (20) in its installed state matches that of the bottom of the base frame (10). In other words, the bottom frame (24) is provided to have a bottom surface at the same height as the bottom surface of the base frame (10) that is in contact with the substructure or the ground in the installed state of the support bracket (20), so that it can be supported in contact with the substructure or the ground together with the base frame (10). The bottom frame (24) may have a shape that protrudes from the bottom surface of the first coupling plate (21). The bottom frame (24) may have a shape that extends in the longitudinal direction of the support bracket (20).

[0073] In the installed state of the support bracket (20), the guide projection (15) formed on the bottom surface (109) of the recess (11) can be inserted into one of a pair of third holes (28) formed through the second coupling plate (22) of the support bracket (20). The third hole (28) formed through the second coupling plate (22) has the same diameter as the first hole (26) formed through the first coupling plate (21), so the guide projection (15) may have a smaller diameter than the third hole (28). A second coupling hole (17) may be provided on the bottom surface (109) of the recess (11) and formed spaced apart horizontally from the guide projection (15). The second coupling hole (17) may be formed spaced apart from the guide projection (15) and the base frame (10) in the longitudinal direction. The distance between the guide projection (15) and the second coupling hole (17) may be the same as the distance between a pair of third holes (28) of the second coupling plate (22) of the support bracket (20).

[0074] The other of the second coupling hole (17) formed on the bottom surface (109) of the recess (11) and the third hole (28) formed on the second coupling plate (22) of the support bracket (20) can be coupled with a screw or the like while aligned at a corresponding position. Here, the third hole (28) is formed with a diameter larger than that of the second coupling hole (17) by a predetermined range, thereby solving the problem where the two holes (28, 17) do not overlap when aligned by the coupling of the guide projection (15) or when the support bracket (20) is supported on the second surface (102) in the direction of gravity, making it difficult to combine with a screw or the like, and thus improving the convenience of coupling or assembly.

[0075] The guide projection (15) can be configured to be used in both the storage state and the installation state of the support bracket (20). That is, if the width direction length from one side plate (23) of the support bracket (20) to the adjacent first hole (26) is set to be equal to the height from the first coupling plate (21) of the support bracket (20) to the third hole (28), the guide projection (15) can be used to be inserted into one first hole (26) in the storage state of the support bracket (20) and inserted into one third hole (28) in the installation state.

[0076] FIGS. 10 to 12 illustrate a bracket assembly according to another embodiment of the present invention. Specifically, FIG. 10 is a perspective view illustrating a base frame (10) of a bracket assembly according to another embodiment of the present invention. FIG. 11 is a perspective view illustrating a storage state of a bracket assembly according to another embodiment of the present invention. FIG. 12 is a perspective view illustrating an installation state of a bracket assembly according to another embodiment of the present invention.

[0077] In another embodiment of the present invention, there may be a difference from the preceding embodiment in that it further includes a third surface (103) and a fourth surface (104) that partition the recess (11), and the description of the remaining components, excluding the differences, may be applied in the same way as in the preceding embodiment. Therefore, common details will be omitted, and another embodiment of the present invention will be described below focusing on the differences.

[0078] Referring to FIGS. 10 to 12, a bracket assembly according to another embodiment of the present invention may further include a third surface (103) and a fourth surface (104).

[0079] The third surface (103) and the fourth surface (104) are located in the recess (11) and can be positioned perpendicular to the longitudinal direction of the base frame (10) to partition the recess (11). The third surface (103) and the fourth surface (104) can be spaced apart parallel to each other in the longitudinal direction of the base frame (10) and face each other. The third surface (103) and the fourth surface (104) can be positioned perpendicular to the first surface (101) and the second surface (102). The first surface (101), the second surface (102), the third surface (103), and the fourth surface (104) can form the inner surface of the partitioned space formed in the recess (11). The bottom surface (109) can be positioned perpendicular to all of the first surface (101), the second surface (102), the third surface (103), and the fourth surface (104). The support bracket (20) can be accommodated in the partitioned space of the recess (11) partitioned by the third side (103) and the fourth side (104). In order for the support bracket (20) to be accommodated in the partitioned space, the length (230) of the support bracket (20) may be smaller than the distance between the third side (103) and the fourth side (104). The width (220) of the support bracket (20) may be smaller than the distance between the first side (101) and the second side (102). The height (210) of the support bracket (20) may be smaller than the depth of the recess (11).

[0080] The support bracket (20) may be connected in an installed state such that a portion of it protrudes outside the recess (11), and in this case, another portion of the support bracket (20) may be located in the partitioned space of the recess (11) partitioned by the third surface (103) and the fourth surface (104). At this time, the width (220) of the support bracket (20) may be smaller than the distance between the third surface (103) and the fourth surface (104). The height (210) of the support bracket (20) may be smaller than the distance between the first surface (101) and the second surface (102).
