Description

Technical Field

[0001] This invention relates to a technique for constructing a battery in a vehicle, such as an electric vehicle. Background Technology

[0002] Hybrid vehicles, electric vehicles, and the like are equipped with batteries to provide the power needed to drive the vehicle.

[0003] Typically, batteries are installed in vehicles in the form of battery packs, which contain multiple battery modules, each of which includes multiple battery cells.

Figure 2 Only battery cell 3 and its insertion in the formation are shown. Figure 1 A perspective view of the insertion rod 5 between the battery cells 3 of the battery module 1.

[0059] Figure 6 This is a schematic diagram showing a battery module 1 in which multiple insertion rods 5 are inserted, and... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Unlike the battery module 1, it is shown that the battery module 1 can be assembled with multiple inserted rods 5.

[0060] Figure 7 To show Figure 1 A schematic diagram of a battery module 1 installed in a battery housing 7, wherein a first protrusion 9 and a second protrusion 11 protruding laterally from both sides of the battery module 1 in opposite directions are respectively fixed to a rod mounting bracket 13 and a first internal component 15, and a mounting flange 19 of an end plate 17 is fixed to a second internal component 21.

[0061] Figure 8 To show a top view of battery casing 7, Figure 1 The battery module 1 is inserted into the battery housing 7, and the insertion rod 5 is inserted into the middle part of each battery module 1.

[0062] Figure 9 For along Figure 8 The cross-sectional view taken by line IX-IX shows that the first protrusion 9 is connected to the rod mounting bracket 13 by mounting bolt 37, thereby ensuring a gap L between the battery housing 7 and the battery module 1 housed therein, thus providing space to cushion impacts in the event of a collision or other accident.

[0063] Figure 10 Only shown Figure 8 A schematic diagram of the battery module 1 shows that, in the event of expansion, a second internal member 21 supports the battery module 1. Figure 11 To conceptually demonstrate Figure 10 A detailed schematic diagram of part A focuses on the connection status of mounting bolt 37.

[0064] For reference only. Figure 10 The arrow in the image represents the pressure generated by the expansion of battery cell 3.

[0065] Reference Figures 1 to 11 The vehicle battery mounting structure of the present invention includes a plurality of battery modules 1 arranged in a plane, wherein each battery module includes: at least one insertion rod 5 inserted between a plurality of battery cells 3 stacked in one direction; a pair of end plates 17 disposed at both ends of the stacked battery cells 3; and at least one engaging member 23 for connecting and securing the insertion rod 5 to the pair of end plates 17.

[0066] In other words, according to such Figure 7 and Figure 8 The vehicle battery mounting structure shown has multiple battery modules 1 arranged in a plane within the battery housing 7, such that the insertion rods 5 of each battery module 1 are aligned with each other along a direction perpendicular to the stacking direction of the battery cells 3 of the battery module 1, thereby allowing the insertion rods 5 in the battery module 1 to provide rigidity to the battery housing 7 in addition to their own function.

[0067] For example, when an external impact is applied along the longitudinal direction of the insertion rod 5, the insertion rod 5 can act as a support for such an external impact, ultimately protecting the battery cell 3 of the battery module 1.

[0068] This allows for the elimination of some internal components traditionally housed in the battery casing 7, relatively increasing the effective load of the battery cell 3, while ensuring sufficient rigidity of the battery pack through the insertion rod 5. This ultimately increases the driving range of electric vehicles, etc., and ensures that the required rigidity and protection of the battery pack meet or exceed conventional levels.

[0069] The insertion rod 5 includes a main body section 25 that contacts the surface of the battery cell 3, and a first protrusion 9 and a second protrusion 11 that protrude laterally from the main body section 25 in opposite directions in a direction perpendicular to the stacking direction of the battery cell 3.

[0070] In other words, the main body section 25 is formed to include a plane that is substantially the same as the plane of the adjacent battery cell 3, which helps to form surface pressure of the battery cell 3, and the first protrusion 9 and the second protrusion 11 are respectively formed to protrude laterally from the battery module 1 in opposite directions.

[0071] The main body section 25 of the insertion rod 5 may have at least one partition 27 inside, and the partition 27 may be formed in a shape that extends linearly in the protruding direction of the first protrusion 9 and the second protrusion 11.

[0072] In other words, the insertion rod 5 can be formed from a hollow member including the partition wall 27, such that the insertion rod can be formed from a metal extrusion material or the like that extends in the longitudinal direction of the insertion rod 5.

[0073] In an exemplary embodiment of the invention, the insertion rod 5 includes a cross-sectional structure of an extruded material shape, the extruded material shape including a plurality of partitions 27 in the main body section 25, and a first protrusion 9 and a second protrusion 11 configured to protrude laterally from two vertically adjacent partitions 27 in the main body section 25 in opposite directions.

[0074] In the current manner, the insertion rod 5, formed by a hollow member with multiple partitions 27, has minimal weight while ensuring sufficient rigidity of the battery module 1 and the battery pack.

[0075] Here, the first protrusion 9 and the second protrusion 11 can be formed to protrude at different heights on opposite lateral sides of the main body section 25.

[0076] The first protrusion 9 and the second protrusion 11 can be configured to have a height difference, such that when adjacent battery modules 1 are installed together, the adjacent first protrusion 9 and second protrusion 11 of adjacent battery modules 1 vertically overlap each other and are joined together by bolts or the like, thereby ensuring the joining force and support rigidity between battery modules 1.

[0077] The first protrusion 9 and the second protrusion 11 are respectively engaged with the first internal member 15 and the rod mounting bracket 13 disposed in the battery housing 7, wherein the first internal member 15 is configured to extend along the stacking direction of the battery cells 3 and span the space between the battery modules 1 housed in the battery housing 7, and the rod mounting bracket 13 is configured to protrude inward from the inner wall surface of the battery housing 7.

[0078] Therefore, as Figure 9 As shown, a gap L is provided between the inner wall surfaces of the battery module 1 and the battery housing 7 to provide a buffer space, prevent external impacts such as collision accidents, and effectively protect the battery module 1 housed in the battery housing.

[0079] For reference, in an exemplary embodiment of the present invention, the first internal member 15 extends along the stacking direction of the battery cells 3 of the battery module 1, while the second internal member 21 is configured to be perpendicular to the stacking direction of the battery cells 3, that is, perpendicular to the first internal member 15.

[0080] On the other hand, at least one connecting member 23 is disposed on the upper and lower sides of the stacked battery cells 3.

[0081] In an exemplary embodiment of the invention, at least one joining member 23 includes a module cover 29 that covers the entire upper or lower side of the stacked battery cells 3 of the battery module, and at least one clamp 31 formed in the form of a strip extending along the stacking direction of the stacked battery cells 3.

[0082] The module cover 29 is engaged to a pair of end plates 17 at both ends and to the insertion rod 5 at the portion facing the insertion rod 5.

[0083] Furthermore, the clamp 31 includes a curved portion 33 that bends toward the insertion rod 5 at the portion facing the insertion rod 5, wherein the clamp 31 is engaged to a pair of end plates 17 at both ends and to the insertion rod 5 at the curved portion 33.

[0084] In an exemplary embodiment of the invention, the engagement between the module cover 29 and the insertion rod 5, and the engagement between the insertion rod 5 and the clamp 31, are shown to be performed by a plurality of fastening bolts 35, but other fastening methods such as welding may also be used.

[0085] The end plate 17 includes a mounting flange 19 projecting along the stacking direction of the battery cells 3, wherein the mounting flange 19 engages with a second internal member 21, the second internal member 21 extending in a direction perpendicular to the stacking direction of the battery cells 3 housed in the battery housing 7, the mounting flange 19 being provided with at least one mounting hole 39 through which a mounting bolt 37 passes to engage the mounting flange 19 with the second internal member 21.

[0086] The mounting hole 39 is formed as a slot that extends in the stacking direction of the battery cells 3. In an exemplary embodiment of the invention, the slot may include an elongated hole.

[0087] Therefore, even if expansion occurs in the battery cell 3 of the battery module 1, the expanded battery cell 3 is initially supported by the fastening force provided by the mounting bolt 37 and the second internal component 21.

[0088] Since the mounting hole 39 is formed as an elongated hole, the mounting bolt 37 can be prevented from breaking even when the mounting flange 19 moves relative to the second internal member 21 due to the expansion of the battery cell 3, and continuous and stable support is provided for the battery module 1.

[0089] Here, since the second internal member 21 is formed as a single member that spans the battery housing 7 to support the multiple battery modules 1 arranged in the longitudinal direction of the second internal member 21, even if the tightening force of the mounting bolt 37 is insufficient, the pressure caused by the expansion of the battery module 1 can be stably supported by the second internal member 21.

[0090] In exemplary embodiments of the invention, a vehicle may be referred to as a vehicle based on a concept that includes various means of transportation. In some cases, a vehicle may be interpreted as being based on a concept that includes not only various land vehicles that travel on roads, such as cars, motorcycles, trucks, and buses, but also various means of transportation such as airplanes, drones, ships, etc.

It will be further understood that the term “connection” or its derivatives refer to both direct and indirect connections.

[0092] The term "and / or" can include a combination of multiple related listed items or any one of multiple related listed items. For example, "A and / or B" includes all three cases, such as "A", "B", and "A and B".
