[0001] The present invention relates to a wire holder, a wire holder assembly including the same, and a battery pack. The present invention relates to a battery module, a battery pack including the same, and an automobile. The application is a priority claim application for Korean Patent Application No. 10-2024-0187306 filed on December 16, 2024, and all contents disclosed in the specifications and drawings of said applications are incorporated by reference into the present application.

[0002] Secondary batteries, which possess electrical characteristics such as high energy density and high applicability across product groups, are widely applied not only to portable devices but also to electric vehicles (EVs) or hybrid electric vehicles (HEVs) powered by electric sources. Secondary batteries can be manufactured in the form of battery packs. A battery pack may include battery modules, and a battery module may include one or more secondary battery cells.

[0003] To increase the charge and discharge capacity of a battery pack, internal components need to be compactly housed, which can thereby improve charge / discharge capacity and energy density. However, since the internal components of a battery pack have various shapes, problems may arise where it becomes difficult to maximize the battery pack's energy density if some of the internal space remains empty and underutilized, or if specific components occupy more space than necessary.

[0004] Therefore, it is necessary to maximize the energy density of the battery pack by utilizing the space occupied by the internal components as efficiently as possible and minimizing empty space.

[0048] Hereinafter, a wire holder according to embodiments of the present invention, a wire holder assembly including the same, and a battery pack will be described in detail with reference to FIGS. 1 to 9.

[0049] FIG. 1 is a perspective view illustrating a wire holder according to an embodiment of the present invention. FIG. 2 is a drawing illustrating a state in which a wire is held in a wire holder according to an embodiment of the present invention. FIG. 3 is a cross-sectional view illustrating a state in which a wire is held in a wire holder according to an embodiment of the present invention from another angle.

[0050] Referring to FIGS. 1 to 3, the wire holder (100) may include a main body (110) having a holding space (120), a connecting part (130), and a door (140).

[0051] A wire holder (100) is intended to hold a plurality of wires (200). The plurality of wires (200) may be referred to as a wire bundle, a wire bundle, etc. In the present invention, a wire (200) may refer to a wire capable of supplying electrical signals, electrical energy, etc. In the present invention, the meaning of 'holding' a plurality of wires (200) may mean tying the plurality of wires (200) to a specific location, supporting them, and restricting their movement.

[0052] The main body (110) can form the overall appearance of the wire holder (100). The wire holder (100) may include a holding space (120) defined as the space inside. A plurality of wires (200) may be held in the holding space (120).

[0053] The wire holder (100) can hold a plurality of wires (200) that have passed through the holding space (120) at a specific location. The holding space (120) provides a space through which the wires (200) can pass and can also be a space where the wires (200) are held.

[0054] The coupling portion (130) may be configured so that a wire holder (100) can be coupled with another wire holder (100). For example, referring to FIGS. 1 to 3, the coupling portion (130) may include a first coupling portion (131) and a second coupling portion (132). The second coupling portion (132) may be configured in a shape that can be coupled with the first coupling portion (131). The first coupling portion (131) of one wire holder (100) may be configured so that it can be coupled with the second coupling portion (132) of another wire holder (100). The first coupling portion (131) and the second coupling portion (132) may be disposed on different sides of the main body (110). For example, the first coupling part (131) may be provided on the upper surface (+Z-axis direction) of the main body (110), and the second coupling part (132) may be provided on the lower surface (-Z-axis direction) of the main body. The coupling between the wire holders (100) through the coupling part (130) will be explained in more detail below with reference to FIG. 4.

[0055] The door (140) may be configured to hold a plurality of wires (200) inside the holding space (120) or to release the plurality of wires (200) from the holding state.

[0056] For example, the door (140) may be configured to move between a holding position that holds a plurality of wires (200) and a release position that releases the plurality of wires (200). FIG. 1 illustrates the door (140) in the release position, and FIG. 2 and FIG. 3 illustrate the door (140) in the holding position. When the door (140) is positioned in the release position as shown in FIG. 1, the wires (200) may enter the interior of the holding space (120) or exit the holding space (120). When the door (140) is positioned in the holding position as shown in FIG. 2 and FIG. 3, the movement of the wires (200) between the interior and exterior of the holding space (120) may be restricted.

[0057] The door (140) may further include a hinge (141) for movement in a holding position and a release position. The hinge (141) may be configured so that the door (140) can rotate relative to the main body (110).

[0058] Referring to FIGS. 1 and 2, the hinge (141) may be configured in various embodiments that allow the door (140) to perform relative rotational movement with respect to the main body (110). For example, the hinge (141) may be configured as a separate physical component from the main body (110) or the door (140) to allow the door (140) to rotate relative to the main body (110). As another example, the hinge (141) may be an area having elasticity and flexibility as a part of at least one of the main body (110) and the door (140). In addition, the hinge (141) may include other configurations that allow the door (140) to rotate relative to the main body (110), and the structure and method thereof are not particularly limited.

[0059] The main body (110) and the door (140) may further include configurations that allow the door (140) to be stably fixed in a holding position. For example, referring to FIGS. 1 and 2, the door (140) may include a hook-shaped door hook (142), and the main body (110) may have a catch groove (111) formed therein to which the door hook (142) can be caught and fixed. The catch groove (111) may be formed at a position where the door hook (142) can be caught when the door (140) is in a holding position, as shown in FIG. 2.

[0060] A door (140) may be provided on a side of the main body (110). A side of the main body (110) may refer to a surface positioned approximately perpendicular to the upper surface (a surface facing the +Z-axis direction) and the lower surface (a surface facing the -Z-axis direction) of the main body (110). The door (140) may be one of the sides of the main body (110). That is, the door (140) may be a movable surface among the sides of the main body (110).

[0061] When the door (140) is in the holding position, the inner surface of the door (140) may form part of the inner surface defining the holding space (120) and may hold the wire (200). Conversely, when the door (140) is in the release position, the inner surface defining the holding space (120) is open so that the wire (200) may be released.

[0062] The main body (110) may be partially open so that the wire (200) can pass through the holding space (120) in at least one direction. Specifically, the main body (110) may have two opposing sides open along the extension direction of the wire (200). For example, referring to FIGS. 2 and 3, the wire (200) may be extended in the Y-axis direction, and the main body (110) may be configured so that the wire (200) can pass through the holding space (120) by having two sides perpendicular to the Y-axis direction open.

[0063] The holding space (120) may be configured so that a plurality of wires (200) can be stacked in a specific direction overall. For example, the holding space (120) may be configured such that the width in one direction is less than twice the diameter of the wire (200) so that the wire (200) is stacked in a specific direction within the holding space (120). For example, referring to FIG. 3, the holding space (120) may be configured such that the width (W2) in the X-axis direction is less than twice the diameter (W1) of the wire (200). According to the above embodiment, the wire (200) in the holding space (120) is stacked along the length direction (Z-axis direction) of the wire holder (100), but the stacking may be limited in the width (X-axis direction) of the holding space (120). As described above, the wire holder (100) according to one embodiment of the present invention has a structure in which wires (200) can be stacked in a specific direction, thereby allowing for more efficient use of a narrow space.

[0064] If a wire holder (100) as in the present invention is not used, for example, if multiple wires (200) are bundled together and arranged using PE tape or the like, the width of the wire bundle becomes too thick, making it impossible to use in a narrow space. In the present invention, the wires (200) can be arranged intensively within the wire holder (100) with a narrow width, making it possible to use in a narrow space. Such a wire holder (100) can be manufactured from an injection-molded plastic material made of insulating material.

[0065] FIG. 4 is a perspective view for explaining a wire holder assembly including a wire holder according to one embodiment of the present invention.

[0066] The wire assembly (1000) may be an assembly comprising a plurality of wire holders (100) described with reference to FIGS. 1 to 3. The plurality of wire holders (100) may be joined together by the combination of a first coupling part (131) and a second coupling part (132). FIG. 4 shows a first wire holder (100a) and a second wire holder (100b), but this is merely a minimum example to explain the wire holders (100) that can be joined, and the number of wire holders (100) that may be included in the wire holder assembly (1000) may exceed two and is not limited thereto.

[0067] The first wire holder (100a) and the second wire holder (100b) illustrated in FIG. 4 may each have the same or similar configuration as the wire holder (100) illustrated in FIG. 1 to FIG. 3. The first wire holder (100a) and the second wire holder (100b) may be detachably coupled. For example, the first coupling part (131) of the first wire holder (100a) may be detachably coupled to the second coupling part (132) of the second wire holder (100b). At this time, the first coupling part (131) and the second coupling part (132) may be configured in a shape that allows them to be coupled to each other in a sliding manner. For example, referring to FIG. 4, the first coupling part (131) may be formed protrudingly, and the second coupling part (132) may be formed recessed in a shape corresponding to the first coupling part (131), so that they can be slidably coupled to each other.

[0068] Referring to FIG. 4, the first wire holder (100a) can be moved in the +Y axis direction or the second wire holder (100b) can be moved in the -Y axis direction, thereby allowing the first coupling part (131) and the second coupling part (132) to be joined in a sliding manner. Conversely, if the first wire holder (100a) with a protruding shape is moved in the -Y axis direction or the second wire holder (100b) is moved in the +Y axis direction, the two wire holders (100) can be separated from each other.

[0069] According to a wire holder assembly (1000) according to one embodiment of the present invention, a holding space (120) of a plurality of wire holders (100a, 100b) is configured so that a plurality of wires (200) can be stacked, and the direction in which at least some of the plurality of wire holders (100) are joined to each other by a first joining part (131) and a second joining part (132) can be configured in the same direction as the direction in which the plurality of wires are stacked in the holding space (120). This method of joining can be called "up and down joining" of the wire holder (100). According to the above embodiment, the wire holders (100) can be connected to the upper and lower parts depending on the number of wires (200) to be held, so that expansion is easy and the wires (200) can be organized by efficiently utilizing a narrow space.

[0070] In the present specification, the direction in which the wires (200) are stacked may refer to a component of the common stacking direction when three or more wires are stacked two or more times within one holding space (120).

[0071] For example, referring to FIGS. 3 and 4, a plurality of wires (200) in the first wire holder (100a) and the second wire holder (100b) can be stacked in the Z-axis direction, and the first wire holder (100a) and the second wire holder (100b) can also be joined in the Z-axis direction.

[0072] According to the above embodiment, by stacking and aligning a plurality of wires (200) continuously in a specific direction, a narrow space can be utilized more efficiently.

[0073] FIG. 5 is a drawing for explaining a wire holder according to another embodiment of the present invention. FIG. 6 is a drawing for explaining a state in which a wire is held in a wire holder according to another embodiment of the present invention.

[0074] The wire holder (100) described below with reference to FIGS. 5 and FIGS. 6 may include a configuration identical or similar to the wire holders described above with reference to FIGS. 1 to 4, and descriptions of overlapping configurations may be omitted.

[0075] An uneven structure configured to guide the holding position of the wire (200) may be formed on the inner wall of the main body (110), which defines the holding space (120), which is the internal space of the main body (110). For example, referring to FIGS. 5 and 6, the uneven structure may be formed on the inner wall of the main body (110) by repeating main body grooves (112) and main body protrusions (113). The size and shape of the main body grooves (112) and main body protrusions (113) may be appropriately changed according to the size and shape of the wire (200) to be held.

[0076] FIG. 6 illustrates a state in which a plurality of wires (200) are held inside the wire holder (100) shown in FIG. 5, and the door (140) is moved to the holding position. According to the above embodiment, the plurality of wires (200) held inside the holding space (120) can be stacked at a predetermined position. The user of the wire holder (100) can more easily and stably hold the plurality of wires (200) at a predetermined position due to the arrangement of the main body groove (112) and the main body protrusion (113).

[0077] Meanwhile, an uneven structure configured to guide the holding position of the wire (200) can be formed not only on the inner wall of the main body (110) but also on the inner surface of the door (140). For example, referring to FIGS. 5 and 6, the door protrusion (143) and door groove (144) can be repeated on the inner surface of the door (140) to form an uneven structure.

[0078] Since the inner surface of the door (140) acts as an inner wall defining the holding space (120) just like the inner surface of the main body (110), the door protrusion (143) and the door groove (144) can stably hold the wire inside the holding space (120) at a predetermined position, just like the main body groove (112) and the main body protrusion (113).

[0079] FIG. 7 is a drawing for illustrating a wire holder assembly including a wire holder according to another embodiment of the present invention.

[0080] The wire holder (100) described below may include a configuration identical or similar to the wire holders described above with reference to FIGS. 1 to 6, and descriptions of overlapping configurations may be omitted.

[0081] As described above with reference to FIG. 4, the first coupling portion (131) of the first wire holder (100a) can be detachably coupled to the second coupling portion (132) of the second wire holder (100b). Here, the direction in which the first wire holder (100a) and the second wire holder (100b) are coupled to each other can be configured to be the same direction as the direction in which a plurality of wires are stacked in the holding space (120).

[0082] The holding space (120) can be configured so that a plurality of wires can be stacked.

[0083] Referring to FIG. 7, the second wire holder (100b) and the third wire holder (100c) can also be detachably coupled to each other. For example, the third coupling part (133) of the third wire holder (100b) can be detachably coupled to the fourth coupling part (134) of the second wire holder (100b).

[0084] The third coupling part (133) and the fourth coupling part (134) are each provided on the side of the main body (110) and may be configured in a shape that allows them to be coupled to each other. The side of the main body (110) may refer to a surface positioned approximately perpendicular to the upper surface (the surface facing the +Z-axis direction) and the lower surface (the surface facing the -Z-axis direction) of the main body (110). For example, the third coupling part (133) and the fourth coupling part (134) may be configured in a shape that allows them to be coupled to each other in a sliding manner.

[0085] For example, referring to FIG. 7, the third connecting part (133) is formed protrudingly, and the fourth connecting part (134) is formed recessed in a shape corresponding to the third connecting part (133), so that they can be slidably connected to each other. The method of connecting the third connecting part (133) and the fourth connecting part (134) may be the same or similar to the method of connecting the first connecting part (131) and the second connecting part (132).

[0086] As described with reference to other drawings, the wire holder may be provided with a door. According to one embodiment, the door of one wire holder may be provided as a connecting part of another wire holder. In other words, the door of the wire holder may be replaced by a connecting part of another wire holder.

[0087] For example, referring to FIG. 7, the door of the second wire holder (100b) may be provided as the third coupling part (133) of the third wire holder (100c). The third coupling part (133) is a component of the third wire holder (100c) that can be coupled with the fourth coupling part (134), and at the same time, it may also serve as a door defining a portion of the holding space (120) of the second wire holder (100b). Through this configuration and structure, space can be used more efficiently, the number of parts of the wire holder assembly (1000) can be reduced, and it can contribute to weight reduction.

[0088] According to a wire holder assembly (1000) according to one embodiment of the present invention, the direction in which at least some of the plurality of wire holders are joined together by the third joining part (133) and the fourth joining part (134) may be a direction that crosses the direction in which a plurality of wires are stacked in the holding space (120). For example, the direction in which the second wire holder (100b) and the third wire holder (100c) are joined together by the third joining part (133) and the fourth joining part (134) may be configured to be approximately perpendicular to the direction in which a plurality of wires are stacked in the holding space (120). For example, the direction in which the second wire holder (100b) and the third wire holder (100c) are joined together may be configured to be approximately perpendicular to the direction in which a plurality of wires are stacked in the holding space (120). Here, the direction in which the wires (200) are stacked may refer to a common stacking direction component when three or more wires are stacked two or more times within a single holding space (120). For example, referring to FIG. 7, a plurality of wires (200) in the second wire holder (100b) and the third wire holder (100c) are stacked in the Z-axis direction, and the second wire holder (100b) and the third wire holder (100c) can be joined in the X-axis direction. Such a joining method can be referred to as "side joining" of the wire holders.

[0089] Referring to FIG. 7, the vertical and lateral connections between the wire holders may be combined. Specifically, the first wire holder (100a) and the second wire holder (100b) may be vertically connected, and the second wire holder (100b) and the third wire holder (100c) may be laterally connected.

[0090] Referring to FIG. 7, the wire holder (100) may further include one or more mounts (160) positioned on the rear (150) opposite the door (140). The mount (160) is a configuration capable of securing the main body (110) of the wire holder (100) to another configuration. By being coupled to another configuration using the wire (200), the mount (160) can be configured to hold a plurality of wires (200) in appropriate positions. The securing of the main body (110) through the mount (160) is described in more detail below with reference to FIGS. 8 through 10.

[0091] FIG. 8 is a drawing for illustrating a wire holder, a wire holder assembly including the same, and a battery pack according to one embodiment of the present invention. FIG. 9 is a drawing for illustrating a wire holder, a wire holder assembly including the same, and a battery pack according to another embodiment of the present invention. FIG. 10 is a drawing for illustrating a wire holder, a wire holder assembly including the same, and a battery pack according to another embodiment of the present invention.

[0092] The wire holder assembly (1000) illustrated in FIGS. 8 to 10 may include a configuration identical or similar to the wire holder assembly (1000) illustrated in FIGS. 1 to 7.

[0093] Referring to FIGS. 8 to 10, the battery pack (1) may include a plurality of battery modules (not shown) and a pack case (300). The pack case (300) may accommodate a plurality of battery modules inside. The pack case (300) provides a pack top plate (310) and a pack bottom plate (320), and various components of the battery pack (1) may be arranged in the space between them.

[0094] A battery module may include one or more secondary battery cells (not shown). In addition to the battery module, the battery pack may further include electrical components such as a Battery Management System (BMS) capable of controlling the charging and discharging of the battery pack (1), busbars, relays, and sensors. Furthermore, to electrically connect the above embodiments, it is essential to place wires (200) inside the pack case (300). For example, multiple wires (200) may be required to connect the Cell Module Controller (CMC) and the Battery Management Controller (BMC) of the battery module. If a wire holder (100) is not used, these wires (200) must be placed to pass between the battery modules. Since as many battery modules as possible are assembled within a limited space to increase energy density, the space available for placing the wires (200) is reduced, making it difficult to effectively utilize the narrow space.

[0095] In order to increase the charge / discharge capacity of the battery pack (1), components such as battery modules need to be intensively housed inside the pack case (300). As the space occupied by the wire (200) of the pack case (300) is minimized, the density of other components of the battery pack (1) can be increased, and the charge / discharge capacity and energy density of the battery pack (1) can be improved. Through the wire holder assembly (1000) according to the embodiments of the present invention, the space occupied by the wire (200) inside the battery pack (1) can be minimized, and the energy density of the battery pack (1) can be maximized.

[0096] In FIGS. 8 to 10, reference numeral 400 refers to all or part of any components that may be placed inside the pack case (300) of the battery pack (1), including a battery module, and shall be referred to as internal components (400) below. Internal components (400) refer to one or more of various components that may be included in the battery pack (1), such as a battery module, BMS, busbar, relay, or sensor.

[0097] For convenience of explanation, the size of the wire holder assembly (1000) in FIGS. 8 to 10 may be exaggerated, and the space occupied by the wire holder assembly (1000) in the battery pack (1) may be significantly reduced compared to that shown in FIGS. 8 to 10.

[0098] Referring to FIG. 8, the remaining area excluding the internal components (400) in the internal space of the pack case (300) of the battery pack (1) is extended in the Z-axis direction. The wire holder (100) can be fixed in the space between the pack case (300) and the internal components (400), such as the battery module, by being joined vertically as in FIG. 8. The wire holder (100) can fix and organize a plurality of wires (200) in the space between the pack case (300) and the internal components (400).

[0099] Each of the wire holders (100a, 100b) can be coupled to the inner wall of the pack case (300) by one or more mounts (160). The mounts (160) can be configured to secure the main body (110) to the pack case (300) between the main body (110) and the pack case (300). According to the wire holder assembly (1000) of the present invention, by coupling and arranging the wire holders (100a, 100b) in the Z-axis direction (upper surface coupling), a plurality of wires (200) can be stacked and held in a structure that utilizes the remaining space, excluding the internal components (400), as efficiently as possible.

[0100] Referring to FIGS. 9 and 10, in the internal space of the pack case (300) of the battery pack (1), the remaining area excluding the internal components (400) is partially formed to extend in the Z-axis direction and partially formed to extend in the X-axis direction. According to the wire holder assembly (1000) of the present invention, by joining a plurality of wire holders (100a, 100b, 100c) on the upper surface in the Z-axis direction or on the side in the X-axis direction, a plurality of wires (200) can be stacked and held in a structure that allows the remaining space excluding the internal components (400) to be utilized as efficiently as possible.

[0101] The joint shapes and joint directions of the wire holders described above with reference to the drawings are exemplary, and the wire holders can be modified through appropriate combinations such as top joints and side joints depending on the size and shape of the required space.

[0102] As described above, the wire holder assembly (1000) according to the embodiments of the present invention can be used to organize and fix wires inside a battery pack (1), etc. as an assembly of a plurality of wire holders. The wire holders of the wire holder assembly (1000) can be assembled with each other in various shapes and directions to organize wires in accordance with the shape of the remaining space excluding the internal configuration (400), thereby enabling more efficient utilization of the internal space of the battery pack (1) and contributing to an improvement in the energy density of the battery pack (1).

[0103] Some or other embodiments of the present disclosure described above are not exclusive or distinguishable from one another. Some or other embodiments of the present disclosure described above may be used in combination or combined for their respective configurations or functions.

[0104] For example, this means that configuration A described in a specific embodiment and / or drawing and configuration B described in another embodiment and / or drawing can be combined. That is, even if the combination between configurations is not directly described, it means that combination is possible, except where it is described that combination is impossible.

[0105] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of the invention shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
