Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a CCS component, battery module and electrical device. Background Technology

[0002] Currently, battery modules are key components of battery systems in electrical equipment. They are assembled from multiple batteries (individual cells) connected in series or parallel to increase voltage and capacity to meet the power needs of specific applications. They are not only the basis for battery packs, but also an indispensable part of electrical equipment such as electric vehicles, energy storage systems, electronic devices, and industrial equipment.

[0003] In related technologies, battery modules mainly include multiple batteries and CCS components. CCS components mainly include multiple conductive connection bars and brackets. Multiple batteries are arranged in sequence, and each battery has two terminals with opposite polarities. The same terminals of two adjacent batteries are electrically connected through a conductive connection bar to realize the series or parallel connection of batteries. The bracket is set on the batteries, and the conductive connection bar is fixedly installed on the bracket.

[0004] However, the inventors recognized that in actual use, the distance between the terminals of two adjacent batteries in different battery modules is different, and the specific position of the corresponding conductive connector on the bracket is also different. Since the conductive connector in the CCS module is fixedly installed on the bracket in the above-mentioned related technologies, the bracket in the CCS module can only be installed with conductive connectors of one type of battery module, which makes the bracket in the CCS module less versatile.

[0019] A third gap is preset between the inner edge of the slot of the conductive connector bar along the second direction and the buckle protrusion, and a fourth gap is preset between the end of the conductive connector bar along the second direction and the abutting part, wherein the fourth gap is the moving distance of the conductive connector bar along the second direction.

[0023] In some embodiments, the end of the fastener along the third direction has a second beveled structure.

[0024] In some embodiments, a fifth gap is predetermined between the end of the latching member along the second direction and the end of the slot along the second direction, the fifth gap being the moving distance of the conductive connecting bar along the second direction.

[0025] In some embodiments, the bracket further includes a wire threading structure, two wire threading structures are spaced apart on the bracket body along the second direction, the wire threading structure is used to place a connecting wire bundle that is electrically connected to the conductive connection bar, and the snap-fit ​​structure is disposed on the side wall of the wire threading structure along the second direction.

The multiple conductive connection bars and multiple batteries are respectively arranged along the first direction, which may be parallel to the extension direction of the bracket.

Specifically, the conductive connection bars and snap-fit ​​structures are connected by snap-fit, thereby enabling quick connection between the conductive connection bars and the snap-fit ​​structures of the bracket.

[0032] Since the distance between the terminals of two adjacent batteries in different battery modules varies, the conductive connecting strip can be moved relative to the snap-fit ​​structure along the first direction. In other words, the conductive connecting strip and the snap-fit ​​structure are in a movable snap-fit ​​manner to adjust the specific position of the conductive connecting strip at the snap-fit ​​structure so that the welding point of the conductive connecting strip corresponds to the position of the terminals of adjacent batteries in different battery modules on the same side and is electrically connected, so as to realize the series or parallel operation of multiple batteries.

[0036] A third aspect of this application provides an electrical appliance that adopts the following technical solution:

[0037] An electrical device comprising a CCS component or battery module as described above.

[0065] Figure 1 This is an exploded structural diagram of a battery module according to some embodiments of this application. Figure 2 for Figure 1 Enlarged structural diagram at point A in the middle.

[0066] One or more embodiments of this application disclose a CCS component. See also... Figure 1 and Figure 2 The CCS assembly includes a bracket 2 and multiple conductive connection bars 3. The bracket 2 is used to mount multiple batteries 4 of the battery module. The multiple conductive connection bars 3 are arranged in a first direction corresponding to the extension direction of the bracket 2. The ends of the conductive connection bars 3 are used to electrically connect with the terminals of the batteries 4.

[0067] The bracket 2 includes a bracket body 21 and a plurality of snap-fit ​​structures 22. The bracket body 21 is provided with a plurality of snap-fit ​​structures 22 along the side of the second direction. The plurality of snap-fit ​​structures 22 are distributed at intervals along the first direction. The conductive connection row 3 is snapped with the snap-fit ​​structure 22, and the conductive connection row 3 is used to move relative to the snap-fit ​​structure 22 along the first direction. The second direction is perpendicular to the first direction.

[0068] In some embodiments, the first direction may be related to Figure 1 and Figure 2 In the coordinate system, the X-axis is parallel and can refer to the extension direction (length direction) of the bracket 2. Multiple batteries 4 of the battery module and multiple conductive connection bars 3 located on the same side of the batteries 4 are also arranged along the first direction. Multiple snap-fit ​​structures 22 are distributed at intervals along the first direction on the bracket body 21. The second direction can be... Figure 1 and Figure 2 In the coordinate system, the Y-axis is parallel and can refer to the width direction of the bracket 2. Multiple first buckle structures 22 can be provided at both ends of the bracket body 21 along the second direction, such as the front end and the rear end, respectively, and are spaced apart along the first direction. The bracket body 21 can be located between two electrical terminals (e.g., positive terminal and negative terminal) on the same side of the battery 4. Similarly, multiple conductive connection rows 3 are provided at the front end and the rear end of the bracket body 21 along the second direction and are spaced apart along the first direction.

[0069] CCS components are components installed on the batteries in a battery module. They are short for wiring harness board integration, data acquisition integration, or wiring harness isolation board. They are mainly used for electrical connection, thermal management, and mechanical support between multiple batteries in a battery module, and can improve the overall performance of the battery module.

[0070] The snap-fit ​​structure 22 and the bracket 2 can be constructed as an integral structure, thereby improving the mechanical strength of the entire bracket 2.

[0071] Each conductive connection row 3 can be snapped into the corresponding snap-fit ​​structure 22. After snapping, the conductive connection row 3 can move slightly along the first direction by a certain distance so that the welding point of the conductive connection row 3 corresponds to the electrode position of the battery 4, so that the conductive connection row 3 can be electrically connected to the electrode of the battery 4 of different specifications of battery modules.

[0072] The battery module may include a CCS assembly and multiple batteries 4. The CCS assembly includes a bracket 2 and multiple conductive connection bars 3. The bracket 2 can be installed on the multiple batteries 4. The bracket 2 may include a bracket body 21 and multiple snap-fit ​​structures 22. The multiple snap-fit ​​structures 22 are spaced apart on the bracket body 21 along a first direction. The multiple conductive connection bars 3 and the multiple batteries 4 are respectively arranged along the first direction, which may be parallel to the extension direction of the bracket 2. The multiple conductive connection bars 3 can be correspondingly installed on the multiple snap-fit ​​structures 22 spaced apart along the first direction. Specifically, the conductive connection bars 3 and the snap-fit ​​structures 22 are connected by snap-fit, thereby realizing the quick connection between the conductive connection bars 3 and the snap-fit ​​structures 22 of the bracket 2.

[0073] Since the distance between the electrodes of two adjacent batteries 4 in different battery modules is different, the conductive connecting strip 3 can be moved relative to the snap-fit ​​structure 22 along the first direction. In other words, the conductive connecting strip 3 and the snap-fit ​​structure 22 are in a movable snap-fit ​​manner to adjust the specific position of the conductive connecting strip 3 at the snap-fit ​​structure 22 so that the welding point of the conductive connecting strip 3 corresponds to the position of the electrode on the same side of the adjacent batteries 4 of different battery modules and is electrically connected, so as to realize the series or parallel operation of multiple batteries 4. Thus, the conductive connecting strip 3 and batteries 4 of different specifications can be electrically connected through the bracket 2, thereby improving the versatility of the bracket 2 in the CCS module.

[0074] In some embodiments, combined with Figure 2As shown, the buckle structure 22 includes a support plate 220, a first limiting member 221, and a buckle member 222. The support plate 220 and the buckle member 222 are spaced apart on the side of the bracket body 21 along the second direction. At least a portion of the conductive connection row 3 is disposed on the support plate 220. The conductive connection row 3 is provided with a slot 310, which engages with the buckle member 222. A first gap is preset between the inner wall of the slot 310 along the first direction and the buckle member 222.

[0075] In at least one embodiment, the statement that the conductive connection bar 3 is partially disposed on the support plate 220 means that a portion of the conductive connection bar 3 is placed on the support plate 220, and the other portion is electrically connected to the electrode of the battery 4. The slot 310 may be a groove that does not penetrate the conductive connection bar 3, or it may be a through hole that penetrates the conductive connection bar 3.

[0076] When the latching member 222 is inserted into the slot 310 of the conductive connection row 3, a first gap is reserved between the inner side wall of the slot 310 along the first direction and the end of the latching member 222 along the first direction. In other words, the size of the slot 310 along the first direction is larger than the size of the latching member 222 along the first direction.

[0077] In some embodiments, combined with Figure 2 As shown, two first limiting members 221 are spaced apart on the support plate 220 along the first direction, and the two first limiting members 221 are located on opposite sides of the conductive connection row 3. A second gap is preset between the end of the conductive connection row 3 along the first direction and the first limiting member 221. The second gap is greater than or equal to the first gap. The second gap is the moving distance of the conductive connection row 3 between the two first limiting members 221.

[0078] In at least one embodiment, the first limiting member 221 may be a vertical plate structure perpendicularly connected to the support plate 220. After the conductive connecting row 3 is engaged with the snap fastener 222, the two first limiting members 221 are located on opposite sides of the conductive connecting row 3, thereby limiting the conductive connecting row 3 along the first direction through the two first limiting members 221. The distance between the two first limiting members 221 in the snap fastener structure 22 is greater than the dimension of the conductive connecting row 3 along the first direction, so that there is a second gap between the end of the conductive connecting row 3 along the first direction and the first limiting member 221 on one side.

[0079] The conductive connection strip 3 has a bend in the middle so that the size (length) of the conductive connection strip 3 can be changed along the first direction, so that the electrical terminals of two adjacent batteries 4 in different battery modules can be electrically connected through the conductive connection strip 3. Since the length of the conductive connection strip 3 can be changed, the second gap is greater than or equal to the first gap to ensure that there is sufficient adjustment distance between the conductive connection strip 3 and the two first limiting members 221.

[0080] Figure 3 This is a top view schematic diagram of a bracket according to some embodiments of this application. Figure 4 for Figure 3 Enlarged structural diagram at point B in the middle.

[0081] In some embodiments, combined with Figure 3 and Figure 4 As shown, the support plate 220 has a first notch 2201 between two adjacent first limiting members 221, and the bracket body 21 also has a second notch 2202. The second notch 2202 and the first notch 2201 are arranged and connected along the second direction. The fastener 222 is disposed on the bracket body 21 at the corresponding position of the second notch 2202 and extends to the first notch 2201. In the first direction, the first distance between the edge of the first notch 2201 and the fastener 222 is greater than the second distance between the edge of the second notch 2202 and the fastener 222.

[0082] In at least one embodiment, a first notch 2201 and a second notch 2202 may be provided on the support plate 220. The second notch 2202 and the second notch 2202 may be arranged along a second direction. A latching member 222 may be disposed at the edge of the second notch 2202 and extend into the first notch 2201. A first distance is defined between the edge of the first notch 2201 along the first direction and the end of the latching member 222 along the first direction. This first distance can be used... Figure 4 The letter 'c' indicates that the distance between the edge of the second notch 2202 along the first direction and the end of the fastener 222 along the first direction is the second distance, which can be used... Figure 4 The letter 'b' in the text represents...

[0083] Since the first distance (lateral distance) c between the inner edge of the first notch 2201 along the first direction and the side of the fastener 222 is greater than the second distance (lateral distance) b between the inner edge of the second notch 2202 along the first direction and the side of the fastener 222, the fastener 222 can move up and down within the elastic deformation range at the moment of engagement.

[0084] The first notch 2201 causes the first limiting members 221 on both sides to elastically deform at the moment the conductive connector 3 is inserted, reducing the possibility of fracture and plastic deformation. The second notch 2202 allows the buckle 222 to elastically deform at the moment the upper first limiting member 221 elastically deforms at the moment the conductive connector 3 slides in. By pre-setting the second notch 2202, the buckle 222 is easier to bend when it elastically deforms, making it easier to assemble the conductive connector 3.

[0085] Figure 5 This is a partial structural schematic diagram of a bracket according to some embodiments of this application.

[0086] In some embodiments, combined with Figure 4 and Figure 5 As shown, the buckle structure 22 further includes a guide 223, which is disposed on the side of the bracket body 21 along the second direction and is located above the first notch 2201. The guide 223 and the buckle 222 are respectively located on opposite sides of the conductive connection row 3 along a third direction, which is perpendicular to the first direction and the second direction, respectively.

[0087] In at least one embodiment, the guide 223 may be directly disposed on the side of the bracket body 21 along the second direction; or two wire-passing structures 23 spaced apart along the second direction may be disposed on the bracket body 21, and the guide 223 may be disposed on the side of the wire-passing structure 23 along the second direction; for example, a connecting wire harness 1 electrically connected to the conductive connecting strip 3 on the positive terminal side of the battery 4 may be placed in one wire-passing structure 23, and a connecting wire harness 1 electrically connected to the conductive connecting strip 3 on the negative terminal side of the battery 4 may be placed in the other wire-passing structure 23.

[0088] The third direction can be combined with Figure 4 and Figure 5 In a coordinate system, the Z-axis is parallel and can refer to the up and down direction.

[0089] The support plate 220, the fastener 222, the first limiting member 221, and the guide member 223 in the snap-fit ​​structure 22 can be disposed on the side wall of the threading structure 23 along the second direction. The guide member 223 can be located above the first notch 2201, and the number of guide members 223 can be at least one. If the number of guide members 223 is two or more, the two or more guide members 223 can be spaced apart along the first direction.

[0090] After the conductive connecting strip 3 is engaged with the snap fastener 222, the support plate 220 and the snap fastener 222 can be positioned below the conductive connecting strip 3, while the guide 223 can be positioned above the conductive connecting strip 3. Thus, the snap fastener 222 can be engaged with the conductive connecting strip 3, and the support plate 220 can support the conductive connecting strip 3 from below. The support plate 220 and the guide 223 can limit the movement along a third direction. Furthermore, the guide 223 helps the conductive connecting strip 3 to be inserted between the two first limiting members 221 to guide it, thereby improving the assembly efficiency of the conductive connecting strip 3 and the snap fastener 222.

[0091] In some embodiments, combined with Figure 5 As shown, the guide member 223 has a first oblique structure 2230 at its end along the second direction, and the first oblique structure 2230 is inclined relative to the conductive connection row 3.

[0092] In at least one embodiment, a first bevel structure 2230 may be provided at the end of the guide member 223 along the second direction, for example at the end away from the wire threading structure 23. The first bevel structure 2230 can be understood as having a bevel or bevel between the side and bottom surface of the end of the guide member 223 away from the wire threading structure 23, for example, the rear end. This can further improve the ease of connection between the conductive connection bar 3 and the bracket 2 through the first bevel structure 2230.

[0093] In some embodiments, combined with Figure 5 As shown, the buckle structure 22 further includes a second limiting member 224, which is disposed on the bracket body 21 and extends along the first direction. The second limiting member 224 is located on one side of the conductive connection row 3 along the second direction, and the second limiting member 224 is set at an angle to the extension direction of the guide member 223.

[0094] In at least one embodiment, the second limiting member 224 may be a vertical plate structure that is perpendicularly connected to the bracket body 21. The second limiting member 224 may be disposed on the bracket body 21. The second limiting member 224 may be part of the threading structure 23, or the second limiting member 224 may be located on one side of the threading structure 23 along the second direction.

[0095] Since the second limiting member 224 can extend along the first direction and the guide member 223 can extend along the second direction, the second limiting member 224 can be set at an angle to the guide member 223, for example, perpendicularly.

[0096] After the conductive connection row 3 is engaged with the snap fastener 222 of the snap fastener structure 22, since the second limiting member 224 is located on one side of the conductive connection row 3 along the second direction, the second limiting member 224 and the snap fastener 222 can limit the conductive connection row 3 along the second direction, which can further improve the connection stability of the conductive connection row 3 and the bracket 2 on the basis of the snap fastener connection.

[0097] In some embodiments, combined with Figure 4 As shown, the second limiting member 224 may be located between the edges of the second notch 2202 and the first notch 2201 along the second direction.

[0098] In at least one embodiment, the second notch 2202 extends toward the positive Y-axis relative to the first notch 2201, or in other words, the second notch 2202 is located along the first notch 2201. Figure 4 The side of the positive Y-axis in the coordinate system.

[0099] Because a second limiting member 224 is provided between the edge of the second notch 2202 along the second direction and the edge of the first notch 2201 along the second direction, and the second limiting member 224 extends along the first direction, wherein the distance between the edge of the second notch 2202 along the second direction and the end of the guide member 223 along the second direction is greater than the length of the guide member 223 along the second direction, and the difference in length between the two is [value missing]. Figure 4 The value 'a' in the figure is equivalent to increasing the length of the buckle 222 along the second direction. This allows the conductive connection row 3 to bend due to elastic deformation of the buckle 222 at the moment it is snapped into the buckle structure 22. This length difference 'a' not only increases the bending capacity of the buckle 222, preventing plastic deformation caused by excessive instantaneous force and thus preventing the buckle 222 from breaking, but also ensures that the second limiting member 224 has a certain width along the second direction, thereby limiting the forward and backward movement range of the conductive connection row 3 along the second direction.

[0100] Figure 7 This is one of the partial structural diagrams of a CCS component according to some embodiments of this application.

[0101] In some embodiments, combined with Figure 7 As shown, the conductive connection bar 3 has a recessed platform 31 on its end face along a third direction, and the recessed platform 31 has the slot 310. The bottom surface of the guide member 223 abuts against the recessed platform 31, and the edge of the recessed platform 31 has a trapezoidal structure.

[0102] In at least one embodiment, the recessed platform 31 refers to a recessed platform 31 in the form of a groove on the conductive connection bar 3, and the slot 310 can be opened inside the outer edge of the recessed platform 31.

[0103] After the slot 310 of the conductive connection bar 3 engages with the fastener 222, the bottom surface of the guide member 223 can abut against the recessed platform 31, so that the recessed platform 31, the support plate 220, and the fastener 222 can provide a limiting position in the third direction. Since the edge of the recessed platform 31 has a trapezoidal structure, the two side edges of the recessed platform 31 along the second direction are parallel and can be defined as the first side edge and the second side edge, respectively. The two side edges of the recessed platform 31 along the first direction (which can be defined as the third side edge and the fourth side edge, respectively) are set at an included angle.

[0104] Because the edge of the recessed platform 31 is trapezoidal, the conductive connecting strip 3 can be better assembled with the buckle 222 of the bracket 2 at the moment of sliding in. The trapezoidal structure and the bracket 2 are fitted with a gap. The third and fourth sides of the trapezoidal structure cooperate with the guide 223 to limit the conductive connecting strip 3 along the first direction. The limit is terminated at the midpoint of the hypotenuse of the third and fourth sides of the trapezoidal structure, so that the left and right movement of the conductive connecting strip 3 along the first direction has a final value range.

[0105] Figure 6 This is a partial structural diagram of a snap-fit ​​structure according to some embodiments of this application.

[0106] In some embodiments, combined with Figure 5 and Figure 6 As shown, the fastener 222 includes a fastening plate 2221 and a fastening protrusion 2222, the fastening protrusion 2222 being disposed on the fastening plate 2221; a third gap 2224 is preset between the end of the fastening protrusion 2222 along the second direction and the end of the fastening plate 2221 along the second direction, and the fastening protrusion 2222 is inclined relative to the fastening plate 2221.

[0107] In at least one embodiment, the buckle plate 2221 may be a strip-shaped structure or a plate-shaped structure extending along the second direction, and the buckle protrusion 2222 may protrude from the upper surface of the buckle plate 2221. Since a third gap 2224 is preset between the end of the buckle protrusion 2222 along the second direction and the end of the buckle plate 2221 along the second direction, in other words, the buckle protrusion 2222 is provided between the two ends of the buckle plate 2221 along the second direction, and the buckle protrusion 2222 has an inclined surface that is angled with the buckle plate 2221.

[0108] Since the buckle protrusion 2222 is inclined relative to the buckle plate 2221, and a third gap 2224 is preset between the end of the buckle protrusion 2222 along the second direction and the end of the buckle plate 2221 along the second direction, the conductive connecting strip 3 slides upward along the buckle protrusion 2222 through the third gap 2224. Then, the buckle member 222 undergoes elastic deformation in the third direction (vertical direction) so that the buckle member 222 can be quickly snapped into the slot 310, thereby improving the snapping convenience between the buckle member 222 and the conductive connecting strip 3.

[0109] Figure 8 This is one of the structural schematic diagrams of a bracket according to some embodiments of this application. Figure 9 for Figure 8 Enlarged structural diagram at point C.

[0110] In some embodiments, combined with Figure 5 , Figure 8 and Figure 9 As shown, the buckle structure 22 further includes an abutment portion 225, which is set at an angle to the second limiting member 224, and the abutment portion 225 is located below the guide member 223;

[0111] A third gap 2224 is preset between the inner edge of the slot 310 of the conductive connection row 3 along the second direction and the buckle protrusion 2222, and a fourth gap is preset between the end of the conductive connection row 3 along the second direction and the abutment portion 225. The fourth gap is the moving distance of the conductive connection row 3 along the second direction.

[0112] In at least one embodiment, the abutment portion 225 and the second limiting member 224 are arranged at an angle, meaning that the second limiting member 224 extends along a first direction, and a portion of the second limiting member 224 extends toward a second direction to form the abutment portion 225, such that the abutment portion 225 and the second limiting member 224 can be arranged at an angle, for example, perpendicularly, wherein the abutment portion 225 can be located below the guide member 223.

[0113] A predetermined gap is maintained between the end of the abutting portion 225 along the extending direction of the guide member 223 and the second limiting member 224 (this predetermined gap can be used for...). Figure 9 (h in the text represents) makes it easy to insert conductive connectors 3 of different thicknesses at the moment of sliding in, and the abutment part 225 can also play a role in positioning the conductive connectors 3 along the second direction after sliding in.

[0114] When the conductive connector 3 is engaged with the buckle 222, it is locked in place under the guidance of the guide 223. After assembly and fixation, the groove 310 in the conductive connector 3 has a third gap 2224 between the edge of the second direction and the rear end of the buckle protrusion 2222, and a fourth gap is reserved between the end of the conductive connector 3 in the second direction and the abutment 225. These two gaps allow the conductive connector 3 to move in the second direction and restrict its movement when it is dislodged by external factors.

[0115] The conductive connector 3 can be installed using the following process: for example, the conductive connector 3 is manually guided and inserted using the guide member 223. Under the condition that the conductive connector 3 is engaged with the latching structure 22 of the bracket 2, the bottom of the guide member 223 first abuts against the recessed platform 31. Since the bottom of the guide member 223 has a first angled structure 2230, it facilitates the sliding of the recessed platform 31 into the assembly. The latching protrusion 2222 of the latching member 222 abuts against the bottom edge of the conductive connector 3. A third gap is left between the rear end of the latching protrusion 2222 and the inner edge of the slot 310 along the second direction. The conductive connector 3 passes through this predetermined third gap along... The buckle protrusion 2222 facilitates upward sliding, and then the buckle 222 undergoes elastic deformation in the vertical direction, abutting against the abutment part 225 on the side of the conductive connection row 3. The buckle protrusion 2222 of the buckle 222 engages with the slot 310. The buckle protrusion 2222 and the slot 310 also have a first gap along the side wall of the first direction. During transportation or handling, the conductive connection row 3 may move in the first direction (horizontal transverse direction). The distance that the conductive connection row 3 slides by the first gap, the buckle protrusion 2222 will abut against the side wall of the slot 310 to limit the movement of the conductive connection row 3 in the horizontal transverse direction.

[0116] Figure 10 This is an exploded view of a CCS component according to some embodiments of this application. Figure 11 for Figure 10 Enlarged structural diagram at point D.

[0117] In some embodiments, combined with Figure 10 and Figure 11 As shown, the support plate 220 has a third notch 2203 between two adjacent first limiting members 221. The buckle 222 and the support plate 220 are respectively located on opposite sides of the conductive connection row 3 along a third direction. The buckle 222 corresponds to the position of the third notch 2203. The third direction is perpendicular to the first direction and the second direction, respectively.

[0118] In at least one embodiment, the third party can interact with Figure 10 and Figure 11The Z-axis direction in the coordinate system is parallel; it can refer to the up and down direction; the fastener 222 can be located above the third notch 2203. When the conductive connecting row 3 is engaged with the fastener 222, the support plate 220 can be located below the conductive connecting row 3, while the fastener 222 can be located above the conductive connecting row 3. Through the cooperation of the fastener 222 and the support plate 220, not only is the conductive connecting row 3 engaged and fixed, but it can also be used for limiting the position along the third direction.

[0119] Furthermore, the third notch 2203 also allows the first limiting members 221 on both sides of the conductive connection row 3 to undergo elastic deformation at the moment of insertion, reducing the possibility of fracture plastic deformation.

[0120] In some embodiments, combined with Figure 11 As shown, the bracket 2 also includes a wire threading structure 23. Two wire threading structures 23 are spaced apart on the bracket body 21 along the second direction. The wire threading structure 23 is used to place the connecting wire bundle 1 that is electrically connected to the conductive connecting bus 3. The buckle structure 22 is disposed on the side wall of the wire threading structure 23 along the second direction.

[0121] The buckle structure 22 further includes a first connecting portion 226. The side wall of the threading structure 23 along the second direction is set at an angle to the buckle 222. The first connecting portion 226 is located at the connection angle between the threading structure 23 and the buckle 222. In the third direction, the size of the first connecting portion 226 from the end closer to the threading structure 23 is larger than the size from the end farther away from the threading structure 23.

[0122] In at least one embodiment, the first connecting portion 226 may be a connecting rib structure disposed at the connection angle between the threading structure 23 and the fastener 222; the height of the first connecting portion 226 from the end near the threading structure 23 along a third direction is greater than the height of the end away from the threading structure 23 along a third direction, in other words, the first connecting portion 226 may be a wedge-shaped structure.

[0123] The fastener 222 may have an L-shaped structure. For example, the fastener 222 may include a snap-fit ​​plate and a clamping part that are perpendicularly connected to the side wall of the threading structure 23 along the second direction. The snap-fit ​​plate may extend along the second direction, and the clamping part may be located below the end of the snap-fit ​​plate along the second direction.

[0124] By providing a first connecting part 226 at the top of the buckle 222, and the first connecting part 226 tilting downward from one side of the wire threading structure 23, its main function is to allow the buckle 222 to be bent at less than 30° when fixing the conductive connecting strip 3, so that the conductive connecting strip 3 can be more easily fixed and snapped in. At the same time, it protects against the problem that the buckle 222 may break due to excessive bending, and can effectively prevent the buckle from breaking due to excessive bending of the buckle 222.

[0125] In some embodiments, combined with Figure 11 As shown, the end of the buckle 222 along the third direction is a second oblique structure 2223.

[0126] In at least one embodiment, the second beveled structure 2223 means that the end of the fastener 222 along the third direction, such as the bottom end, can be a wedge-shaped structure. In other words, the size of the end of the fastener 222 along the third direction gradually decreases from top to bottom.

[0127] By setting the end of the snap fastener 222 along a third direction as a second beveled structure 2223, and providing a slot 310 on the conductive connecting strip 3, when the conductive connecting strip 3 slides into the snap fastener 2, the conductive connecting strip 3 first abuts against the second beveled structure 2223 of the snap fastener 222. This facilitates the sliding of the conductive connecting strip 3 and allows for simultaneous installation even with different thicknesses. During assembly, the snap fastener 222 slightly bends to facilitate the insertion of the conductive connecting strip 3, and then returns to its normal state upon completion of assembly. In other words, by considering the material and length of the buckle 222, the buckle 222 is allowed to undergo elastic deformation at a certain angle of bending, enabling it to snap into conductive connectors 3 of different thicknesses and simultaneously serve as a limiting element. Since the second oblique structure 2223 is set as an acute angle and the inner plane of the second oblique structure 2223 is higher than the outer plane, it also serves as a longitudinal limiting element in the second direction after the conductive connector 3 is snapped in, making the conductive connector 3 more effectively fixed in the buckle structure 22 and allowing it to move within a set range, thus serving as a limiting element.

[0128] Figure 12 for Figure 10 Enlarged structural diagram at point E in the middle.

[0129] In some embodiments, combined with Figure 12 As shown, a fifth gap is preset between the end of the buckle 222 along the second direction and the end of the slot 310 along the second direction, and the fifth gap is the moving distance of the conductive connection row 3 along the second direction.

[0130] In at least one embodiment, the fifth gap between the end of the latching member 222 along the second direction and the end of the slot 310 along the second direction means that after the slot 310 of the conductive connection row 3 is engaged with the latching member 222, there is a fifth gap between the end of the latching member 222 along the second direction and the end of the slot 310 along the second direction, so that the conductive connection row 3 can move along the second direction within the latching structure 22, and the moving distance is the size of the fifth gap.

[0131] Because a first gap is preset between the side wall of the slot 310 along the first direction and the end of the buckle 222 along the first direction, and a fifth gap is preset between the end of the buckle 222 along the second direction and the end of the slot 310 along the second direction, a certain gap is left around the buckle hole of the conductive connection strip 3 and the buckle 222. After the conductive connection strip 3 is inserted to meet the assembly requirements, it can move back and forth and left and right, but it cannot exceed the specified setting range, such as the first gap and the fifth gap mentioned above. This ensures that the maximum range of motion of the conductive connection strip 3 cannot exceed the failure condition of the bracket 2 in the CCS assembly. Furthermore, on both sides where the conductive connection strip 3 is inserted, a first limiting member 221 is provided to completely limit the conductive connection strip 3 in the first direction.

[0132] Figure 13 This is a second schematic diagram of the structure of a support according to some embodiments of this application. Figure 14 for Figure 13 Enlarged structural diagram at point F in the middle.

[0133] In some embodiments, combined with Figure 13 and Figure 14 As shown, the bracket 2 also includes a wire threading structure 23. Two wire threading structures 23 are spaced apart on the bracket body 21 along the second direction. The wire threading structure 23 is used to place the connecting wire bundle 1 that is electrically connected to the conductive connecting bus 3. The buckle structure 22 is disposed on the side wall of the wire threading structure 23 along the second direction.

[0134] The threading structure 23 includes a groove structure 231 and a wire fixing part 232. The bottom of the groove structure 231 is provided with a clearance hole 233. A plurality of wire fixing parts 232 are spaced apart on the inner wall of the groove structure 231. At least some of the wire fixing parts 232 are located above the clearance hole 233. The connecting wire harness 1 is located between the bottom of the groove structure 231 and the wire fixing part 232.

[0135] In at least one embodiment, combined Figure 1As shown, the CCS assembly may include two sets of connecting wire harnesses 1. The battery 4 in the battery module has two terminals with opposite polarities, such as a positive terminal and a negative terminal. One connecting wire harness 1 is used to connect the conductive connection bar 3 on one side of the battery 4 along the first direction, and the other connecting wire harness 1 can be used to connect the conductive connection bar 3 on the other side of the battery 4 along the first direction. The connecting wire harness 1 can be used to collect at least one of the temperature value and voltage value of the battery 4. The two connecting wire harnesses 1 can be placed in the two wire-passing structures 23 corresponding to the bracket 2 respectively.

[0136] A clearance hole 233 can be opened in the bottom wall of the groove structure 231, and multiple wire fixing parts 232 can be provided in the inner side wall or the top of the inner wall of the wire threading structure 23. The wire fixing parts 232 can be rod-shaped structures, block-shaped structures, plate-shaped structures, strip-shaped structures, etc. that extend along the second direction.

[0137] Because a clearance hole 233 is provided on the bottom wall of the groove structure 231, after the connecting wire harness 1 is inserted into the channel of the wire threading structure 23, it can be connected by tape or cable tie. Specifically, the tape or cable tie can pass through the clearance hole 233 and be wrapped around the fixing part 232, thereby facilitating the connection and fixing of the connecting wire harness 1 at the clearance hole 233. Furthermore, since at least part of the fixing part 232 is located above the clearance hole 233, the connecting wire harness 1 can be fixed and limited in the second direction (vertical).

[0138] In some embodiments, combined with Figure 14 As shown, the side wall of the groove structure 231 connected to the buckle structure 22 includes a plurality of spaced wiring portions 2311. A wiring hole for the connecting wire harness 1 to pass through is formed between two adjacent wiring portions 2311. In the third direction, the size of the wiring portion 2311 at the end away from the bracket body 21 gradually increases to the size of the end of the wiring portion 2311 connected to the bracket body 21.

[0139] In at least one embodiment, the sidewall of the threading structure 23 along the second direction and connected to the snap-fit ​​structure 22 may include a plurality of threading portions 2311 arranged along the first direction. The interval between two adjacent threading portions 2311 may serve as a threading hole. For example, the end of the connecting wire harness 1 is electrically connected to the conductive connecting busbar 3. Other adjacent parts of the connecting wire harness 1 may pass through the threading hole and enter the groove structure 231 for parallel arrangement.

[0140] The third direction can be combined with Figure 14In the coordinate system, the Z-axis is parallel. The size of the wiring part 2311 gradually increases from the end away from the bracket body 21 (top end) to the end where the wiring part 2311 connects to the bracket body 21 (bottom end). In other words, the wiring part 2311 has a structure that is narrow at the top and wide at the bottom, so that the two inner sidewalls of the groove structure 231 along the second direction are both inclined. Its main function is to facilitate the fixing of the wire harness 1 while it passes through the wiring hole. The wiring part 2311 is set to be narrow at the top and wide at the bottom, and the sidewall of the wiring part 2311 along the second direction is inclined from top to bottom. Its main function is to help the effective placement of the wire harness 1 when fixing the wire harness 1 in the groove structure 231 of the bracket 2, because the wire harness 1 is piled up and the width is too wide, making it difficult to place and insert the wire harness. Therefore, the downward inclination of the wiring part 2311 is more conducive to the effective placement of the wire harness 1.

[0141] In some embodiments, combined with Figure 14 As shown, the end of the wiring section 2311 along the first direction is an arc-shaped structure 23111.

[0142] In at least one embodiment, since the connecting harness 1 is subjected to force at each wiring hole due to the pulling effect of the connecting harness 1 at both ends of the bracket body 21 along the second direction after it is placed in the groove structure 231, the end of the wiring part 2311 along the first direction can be set as an arc structure 23111, which can more effectively prevent the connecting harness 1 from being damaged due to the pulling force and causing the overall failure problem.

[0143] Figure 15 This is a schematic diagram of the structure of a conductive connection bar according to some embodiments of this application.

[0144] In some embodiments, combined with Figure 15 As shown, the conductive connection row 3 located at the end in the first direction is provided with a connection hole 32, which is used to connect the terminal block 5 of the battery module through a fastener.

[0145] In at least one embodiment, combined Figure 1As shown, the battery module may include multiple batteries 4, terminal blocks 5, end plates, and CCS components. The multiple batteries 4 are arranged along a first direction to form a row of battery modules, and each battery module may include at least one row of battery modules. If the number of battery modules is two or more, the multiple battery modules may be arranged along a second direction. Two end plates may be spaced apart along the first direction, and the aforementioned battery modules may be placed between the two end plates. The terminal blocks 5 may be mounted on the end plates. A portion of the conductive connection row 3 located at the end in the first direction is welded and fixed to the electrode of the battery 4. Another portion of the conductive connection row 3 has a connection hole 32, and fasteners such as bolts may be vertically inserted through the connection hole 32 of the conductive connection row 3 and the terminal block 5 to fix the conductive connection row 3 to the terminal block 5.
