Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a wire harness isolation plate, a busbar integrated assembly, and an assembly method thereof. Background Technology

[0002] A typical battery contains multiple individual cells. During assembly, these cells' terminals need to be connected via multiple conductive components. However, individually welding and assembling each conductive component significantly impacts production efficiency. Therefore, a wire harness separator is used to fix these components together. However, during assembly, the wire harness separator is typically located between the conductive components and the individual cells. After the conductive components are welded and assembled, the wire harness separator remains fixed inside the battery and cannot be removed, increasing the overall weight of the battery and resulting in some waste. Summary of the Invention

[0003] This application provides a wire harness isolation plate, a busbar integrated assembly, and an assembly method thereof to solve the technical problem that the wire harness isolation plate is fixed inside the battery and cannot be removed during the assembly of conductive components, which increases the weight of the battery and causes some waste.

[0004] In a first aspect, embodiments of this application provide a wire harness separator plate for use in battery assembly, the wire harness separator plate comprising:

[0005] The first partition has a mounting area on its lower surface for mounting conductive components and a locking structure for positioning the conductive components.

[0006] A support structure, wherein the support structure is detachably mounted to the locking structure; wherein,

[0007] When the support structure is installed on the locking structure, the support structure cooperates with the locking structure to lock the conductive element; when the support structure is separated from the locking structure, the locking structure releases the conductive element.

[0008] In the above technical solution, the conductive component is fixed by setting a first separator, and a locking structure and a supporting structure are set. When the supporting structure and the locking structure cooperate, the locking structure locks the conductive component to realize the connection between the first separator and the conductive component. After the conductive component is welded to the battery cell, the supporting structure and the locking structure are separated to unlock the locking structure from the conductive component, so that the first separator can be removed from the battery, recycled and reused, thereby reducing the battery weight and reducing the production cost.

[0009] In some embodiments, the wire harness isolation plate further includes:

[0010] A second partition, detachably mounted on the upper surface of the first partition, and having the aforementioned support structure; wherein,

[0011] When the second partition is installed on the first partition, the support structure cooperates with the locking structure to lock the conductive element. When the second partition is separated from the first partition, the locking structure releases the conductive element.

[0012] In the above technical solution, by setting a second partition and placing the support structure on the second partition, the support structure and the locking structure can be disassembled and assembled by operating the second partition, and the small support structure can be prevented from falling into the battery during assembly.

[0013] In some embodiments, a positioning structure is provided between the first partition and the second partition.

[0014] In the above technical solution, by setting a positioning structure, the locking structure and support structure on the first and second partitions are aligned and cooperated, thereby improving production efficiency.

[0015] In some embodiments, the positioning structure includes a positioning hole provided in one of the first partition and the second partition, and a positioning pin provided in the other.

[0016] In the above technical solution, the positioning structure using holes and pins is simple and easy to process.

[0017] In some embodiments, the first partition is provided with a buckle on the side near the second partition, and the second partition is provided with a slot at the position corresponding to the buckle. When the first partition and the second partition are in contact, the buckle and the slot cooperate to lock.

[0018] In the above technical solution, by setting a buckle and a slot to cooperate, when the second partition is assembled on the first partition, a certain limit is generated between the second partition and the first partition. That is, before the buckle and the slot are unlocked, it can be ensured that the locking structure on the first partition and the supporting structure on the second partition are aligned and cooperated, reducing the probability of the locking structure and the supporting structure being accidentally separated and improving the stability of the overall structure.

[0019] In some embodiments, both the first partition and the second partition are provided with clearance holes, which are adapted to correspond to the welding positions of the conductive components.

[0020] In the above technical solution, clearance holes are provided to facilitate the welding operation of the conductive parts by the welding fixture.

[0021] In some embodiments, the mounting area is used to abut the conductive element at least in the area surrounding the clearance hole, and the lower surface of the second partition abuts the upper surface of the first partition at least in the area surrounding the clearance hole.

[0022] In the above technical solution, by attaching the mounting area of ​​the first separator to the surface of the conductive component, and attaching the second separator to the first separator at the position of the clearance hole, the distance between the first separator, the second separator, and the conductive component in the clearance hole area is reduced. Welding slag generated during the welding process is less likely to fall into the battery box through the first separator, the second separator, and the conductive component, thereby helping to improve the assembly quality of the battery, increase production efficiency, and reduce safety risks.

[0023] In some embodiments, the first partition plate is provided with through holes adapted to correspond to the mounting holes of the conductive element;

[0024] The locking structure includes an elastic protrusion, which is disposed on the lower surface of the first partition and surrounds the through hole;

[0025] The support structure includes a support column, which is movably disposed within the through hole between a supported position and a separated position. When the support column is moved to the supported position, the support column passes through the through hole and is press-fitted with at least a portion of the elastic protrusion, so that the elastic protrusion opens outward and is adapted to be pressed and limited against the inner wall of the mounting hole.

[0026] In the above technical solution, by setting an elastic protrusion, the elastic protrusion can be elastically deformed. The support column expands the elastic protrusion outward and presses it against the inner wall of the mounting hole of the conductive component. The friction generated by the tight fit between the elastic protrusion and the mounting hole is used to fix the conductive component. The structure is simple, the production cost is low, and the installation and disassembly operations are easy and the assembly efficiency is high.

[0027] In some embodiments, the resilient protrusions include a plurality of protrusions and are spaced apart around the through hole.

[0028] In the above technical solution, by setting multiple elastic protrusions, the independent movement of each elastic protrusion is facilitated, and the durability of a single elastic protrusion is improved.

[0029] In some embodiments, the elastic protrusion has a protrusion on one side near the axis of the through hole, the protrusion is near the end of the elastic protrusion away from the first partition, the support column is in an interference fit with the protrusion when it is moved to the support position, and the support column is separated from the protrusion when it is moved to the separation position.

[0030] In the above technical solution, by setting a protrusion, the elastic protrusion can be opened outward when the support column moves to the support position.

[0031] In some embodiments, the protrusion has a guide surface on the side near the first partition, and the guide surface is inclined inward in a direction away from the first partition.

[0032] In the above technical solution, by setting a guide surface on the protrusion, the requirements for machining accuracy can be reduced. The guide surface can guide the support column to move to the position where it is locked with the elastic protrusion, thereby improving assembly efficiency and reducing wear during the assembly process.

[0033] In some embodiments, one of the outer peripheral wall of the support column and the side wall of the protrusion near the support column is provided with a limiting groove, and the other is provided with a limiting protrusion. When the support column moves to the supporting position, the limiting protrusion and the limiting groove are correspondingly engaged.

[0034] In the above technical solution, by setting a limiting groove and a limiting protrusion, the support column has a certain limiting force when it cooperates with the elastic protrusion, so that the support column is not easy to detach from the limiting protrusion on its own, thereby improving the stability of the overall structure.

[0035] In some embodiments, the periphery of the support column near the protrusion is chamfered.

[0036] In the above technical solution, by setting a chamfer on the support column, the resistance generated during the installation of the support column is reduced, the assembly efficiency is improved, and the wear generated during the assembly process is reduced.

[0037] In some embodiments, the side of the elastic protrusion facing away from the axis of the through hole is a smooth surface.

[0038] In the above technical solution, the side of the elastic protrusion away from the axis of the through hole is set to be a smooth surface to facilitate the assembly of the elastic protrusion with the mounting hole of the conductive component.

[0039] Secondly, embodiments of this application provide a busbar integrated component, including:

[0040] The wire harness isolation plate as described in any of the technical solutions in the first aspect;

[0041] A conductive component is installed in the mounting area of ​​the first partition.

[0042] In the above technical solution, after the conductive component is welded to the battery cell, the support structure and the locking structure can be separated to unlock the locking structure from the conductive component, so that the first separator can be removed from the battery, recycled and reused, thereby reducing the battery weight and reducing production costs.

[0043] In some embodiments, the welding position of the conductive element is provided with a welding hole.

[0044] In the above technical solution, welding holes are provided to facilitate the welding fixture to weld the conductive parts to the electrodes of the battery cell.

[0045] In some embodiments, the busbar integration assembly further includes an NTC component, the NTC component being fixedly connected to the conductive element, and the first partition having a clearance groove corresponding to the NTC component.

[0046] In the above technical solution, by mounting the NTC component on the conductive component, the first partition can be separated from the NTC component. By setting a clearance groove on the first partition, the NTC component can be avoided, which facilitates the integration of the NTC component and the conductive component.

[0047] Thirdly, embodiments of this application provide an assembly method for a busbar integrated assembly, the assembly method comprising:

[0048] The busbar integrated assembly as described in any of the technical solutions in the second aspect is arranged on the upper side of multiple battery cells, and the welding position of the conductive element corresponds to the terminal post of the battery cell.

[0049] The welding position of the conductive component is welded to the terminal of the battery cell;

[0050] Separate the support structure from the locking structure to unlock the locking structure from the conductive element;

[0051] Remove the first partition.

[0052] In the above technical solution, after the conductive component is welded to the battery cell, the support structure and the locking structure can be separated to unlock the locking structure from the conductive component, so that the first separator can be removed from the battery, recycled and reused, thereby reducing the battery weight and reducing production costs.

[0053] In some embodiments, the wire harness isolation plate further includes a second partition plate, which is detachably mounted on the upper surface of the first partition plate and has the support structure. The first partition plate is provided with a buckle on the side near the second partition plate, and the second partition plate is provided with a slot at the position corresponding to the buckle. When the first partition plate and the second partition plate are in contact, the buckle and the slot cooperate to lock.

[0054] The step of separating the support structure from the locking structure to unlock the locking structure from the conductive element includes:

[0055] Unlock the buckle from the slot;

[0056] Separate the second partition from the first partition to separate the support structure from the locking structure. Attached Figure Description

[0075] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0077] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0078] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0079] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0080] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0081] In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, the power battery, as the power source, plays an irreplaceable and crucial role. A battery consists of a casing and multiple individual battery cells housed within it. As a core component of new energy vehicles, the battery faces high requirements in terms of both safety and cycle life.

[0082] In conventional batteries, to achieve sufficient power, multiple battery cells are typically stacked within the battery casing. During assembly, multiple conductive components connect the terminals of these cells to create series or parallel connections. However, individually welding each conductive component is cumbersome and affects welding accuracy, significantly impacting production efficiency. Therefore, existing technologies use wire harness separators to fix multiple conductive components together, forming a busbar integrated assembly. This busbar integrated assembly is then connected to the multiple battery cells as a whole, resulting in higher assembly efficiency. However, during assembly, the wire harness separator is generally located between the conductive components and the battery cells. After the conductive components are welded and assembled, the wire harness separator is also fixed inside the battery and cannot be removed, increasing the overall weight of the battery and causing some waste.

[0083] Based on the above considerations, in order to solve the technical problem that the wire harness separator plate is fixed inside the battery and cannot be removed during the assembly of conductive components, which increases the weight of the battery and causes some waste, this application designs a wire harness separator plate for battery assembly. The wire harness separator plate includes a first separator plate and a support structure. The lower surface of the first separator plate is provided with an installation area for installing conductive components and has a locking structure for positioning conductive components. The support structure is detachably installed on the locking structure. When the support structure is installed on the locking structure, the support structure and the locking structure cooperate to lock the conductive components. When the support structure and the locking structure are separated, the locking structure and the conductive components are released from locking.

[0084] In this type of wire harness separator, a first separator is used to fix the conductive component. A locking structure and a support structure are also provided. When the support structure and the locking structure work together, the locking structure locks the conductive component to achieve the connection between the first separator and the conductive component. After the conductive component is welded to the battery cell, the support structure and the locking structure can be separated to unlock the locking structure from the conductive component. This allows the first separator to be removed from the battery, recycled, and reused, thereby reducing battery weight and production costs.

[0085] According to some embodiments of this application, refer to Figures 1-10 This application provides a busbar integrated assembly 2, which includes a wire harness isolation plate 21 and a conductive element 22.

[0086] According to some embodiments of this application, refer to Figures 2-8 This application provides a wire harness isolation plate 21, which includes a first partition 211 and a support structure 2121.

[0087] like Figure 2 As shown, the lower surface of the first partition 211 is provided with a mounting area 2114 for mounting the conductive element 22. The mounting area 2114 is used to cover at least a portion of the conductive element 22. For example, a portion of the first partition 211 is provided with a clearance hole for avoiding the electrode terminal, and another portion is the mounting area 2114. The lower surface of the first partition 211 is provided with a locking structure 2111 for positioning the conductive element 22. The support structure 2121 is detachably mounted on the locking structure 2111. When the support structure 2121 is mounted on the locking structure 2111, the support structure 2121 and the locking structure 2111 cooperate to lock the conductive element 22. When the support structure 2121 and the locking structure 2111 are separated, the locking structure 2111 and the conductive element 22 are released from locking.

[0088] In this embodiment, the conductive element 22 is mounted on the lower surface of the first partition 211, and at least a portion of the locking structure 2111 is disposed on the lower surface of the first partition 211 to position the conductive element 22 and fix it to the first partition 211. The support structure 2121 is detachably mounted on the locking structure 2111, and the support structure 2121 can be installed and removed from the upper surface of the first partition 211, so that the support structure 2121 can be removed when the wire harness separator 21 is placed on the upper surface of the battery cell 11.

[0089] In actual execution, when assembling the conductive component 22 onto the first separator 211, the conductive component 22 can be installed on the lower surface of the first separator 211 and positioned in a specific location by the locking structure 2111. The support structure 2121 is installed from top to bottom onto the locking structure 2111 so that the locking structure 2111 locks the conductive component 22, thereby fixing the conductive component 22 to the first separator 211 to form an assembly. The first separator 211 and the conductive component 22 are transported together to the battery 1 assembly station, and the conductive component 22 is welded to the terminal post of the battery cell 11. It can be understood that the surface of the conductive component 22 facing away from the separator, i.e., the lower surface of the conductive component 22, is used to connect with the terminal post of the battery cell 11, so that after the conductive component 22 is connected to the terminal post of the battery cell 11, the first separator 211 is located on the side of the conductive component 22 facing away from the battery cell 11. The support structure 2121 is disassembled upward from the upper surface of the first partition 211, separating the support structure 2121 from the locking structure 2111, thereby releasing the locking structure 2111 from the conductive element 22, so that the first partition 211 and the conductive element 22 are in a separable state. Then the first partition 211 is removed upward and recycled, so that the first partition 211 can be reused.

[0090] According to the wiring harness isolation plate 21 provided in the embodiments of this application, the conductive member 22 is fixed by setting a first partition plate 211, and a locking structure 2111 and a support structure 2121 are set. When the support structure 2121 and the locking structure 2111 cooperate, the locking structure 2111 locks the conductive member 22 to realize the connection between the first partition plate 211 and the conductive member 22. After the conductive member 22 is welded to the battery cell 11, the support structure 2121 and the locking structure 2111 are separated to unlock the locking structure 2111 from the conductive member 22, so that the first partition plate 211 can be disassembled from the battery 1, recycled and reused, thereby reducing the weight of the battery 1 and reducing the production cost.

[0091] According to the busbar integrated assembly 2 provided in the embodiments of this application, after the conductive component 22 is welded to the battery cell 11, the support structure 2121 and the locking structure 2111 can be separated to unlock the locking structure 2111 from the conductive component, so that the first separator 211 can be disassembled from the battery 1, recycled and reused, thereby reducing the weight of the battery 1 and reducing the production cost.

[0092] According to some embodiments of this application, the busbar integrated assembly 2 may include an NTC (Negative Temperature Coefficient) assembly 23. The first partition 211 may be provided with a clearance groove 214, which may correspond to the NTC assembly 23.

[0093] In this embodiment, the NTC component 23 can be fixedly connected to the conductive element 22. The NTC component 23 can be used to detect the temperature information of the conductive element 22. Specifically, the NTC component 23 is disposed on the lower surface of the first partition 211 so that the NTC component 23 will not hinder the removal of the first partition 211. The NTC component 23 is fixed to the conductive element 22 by hot riveting with a hot riveting post.

[0094] In this embodiment, the NTC component 23 is generally not flat. Therefore, after the NTC component 23 is connected to the conductive element 22, at least part of the NTC component 23 will protrude upwards from the upper surface of the conductive element 22. By providing a relief groove 214 on the first partition 211, the part of the NTC component 23 that protrudes upwards from the conductive element 22 is avoided, thereby ensuring that the first partition 211 and the conductive element 22 are in contact.

[0095] It should be noted that the busbar integrated assembly 2 may also include an FPC (Flexible Printed Circuit) flexible circuit board, which is disposed on the lower surface of the first partition 211 and connected to the conductive element 22 so that the flexible circuit board will not affect the removal of the first partition 211.

[0096] According to the embodiments of this application, by mounting the NTC component 23 on the conductive element 22, the first partition 211 can be separated from the NTC component 23. By providing an avoidance groove 214 in the first partition 211 to avoid the NTC component 23, it is convenient for the NTC component 23 to be integrated with the conductive element 22.

[0097] According to some embodiments of this application, refer to Figure 2The wire harness isolation plate 21 may further include a second partition 212, which is detachably mounted on the upper surface of the first partition 211 and has a support structure 2121. When the second partition 212 is mounted on the first partition 211, the support structure 2121 can cooperate with the locking structure 2111 to lock the conductive element 22. When the second partition 212 is separated from the first partition 211, the locking structure 2111 can release the locking from the conductive element 22.

[0098] It is understandable that there are generally multiple battery cells 11 within the battery 1, and multiple conductive components 22 for connecting the multiple battery cells 11 are also provided. Correspondingly, there are multiple locking structures 2111 on the first partition 211 for positioning the multiple conductive components 22, and multiple support structures 2121 are provided corresponding to the multiple locking structures 2111. The work efficiency of disassembling and assembling multiple support structures 2121 is low. In order to improve the assembly stability of the conductive components 22, each conductive component 22 is provided with at least two locking structures 2111.

[0099] In this embodiment, the first partition 211 may be provided with multiple locking structures 2111, and the wire harness isolation plate 21 may further include a second partition 212. The second partition 212 may have multiple support structures 2121 corresponding to the multiple locking structures 2111. The second partition 212 is detachably installed on the upper surface of the first partition 211. By installing the second partition 212 on the upper surface of the first partition 211, the multiple support structures 2121 are correspondingly installed on the multiple locking structures 2111, thereby completing the connection with the multiple conductive elements 22. By removing the second partition 212 from the first partition 211, the multiple support structures 2121 are separated from the multiple locking structures 2111, thereby releasing the multiple locking structures 2111 on the first partition 211 from the corresponding conductive elements 22.

[0100] In actual operation, after the conductive component 22 is welded, the second partition 212 is first removed upwards, and then the first partition 211 is removed to complete the disassembly operation. The operation is simple and efficient.

[0101] According to the second partition 212 of the present application embodiment, by setting the second partition 212 and setting the support structure 2121 on the second partition 212, the support structure 2121 and the locking structure 2111 can be disassembled and assembled by operating the second partition 212, and the small support structure 2121 can be prevented from falling into the battery during assembly.

[0102] When there are multiple supporting structures 2121 and locking structures 2111, the second partition 212 can drive multiple supporting structures 2121 to cooperate with multiple locking structures 2111 at the same time, and multiple conductive parts 22 can be assembled and fixed at the same time, thereby improving production efficiency.

[0103] According to some embodiments of this application, refer to Figure 2 A positioning structure 215 may be provided between the first partition 211 and the second partition 212.

[0104] In this embodiment, in order to improve the assembly efficiency and accuracy of the first partition 211 and the second partition 212, a positioning structure 215 may be provided between the first partition 211 and the second partition 212 to position the assembly position between the first partition 211 and the second partition 212.

[0105] The specific form of the positioning structure 215 is not limited here, such as Figure 2 As shown, by way of example, one of the first partition 211 and the second partition 212 may be provided with a positioning hole 2113, and the other may be provided with a positioning pin 2123, which can extend into the positioning hole 2113.

[0106] In some embodiments, the positioning structure 215 is offset relative to the geometric center of the first partition 211 and the second partition 212. Taking the first partition 211 and the second partition 212 as a rectangle, the positioning pin 2123 and the positioning hole 2113 are not set at the geometric center of the rectangle, so as to play a guiding and foolproof role.

[0107] In one example, the first partition 211 is provided with a positioning hole 2113, and the second partition 212 is provided with a positioning pin 2123.

[0108] According to the embodiments of this application, by setting a positioning structure 215, the locking structure 2111 and the support structure 2121 on the first partition 211 and the second partition 212 are aligned and cooperated, thereby improving production efficiency.

[0109] According to some embodiments of this application, refer to Figure 1 , Figure 9 and Figure 10 The first partition 211 may be provided with a buckle 2112 on the side near the second partition 212, and the second partition 212 may be provided with a slot 2122 at the position corresponding to the buckle 2112. When the first partition 211 and the second partition 212 are in contact, the buckle 2112 and the slot 2122 cooperate to lock.

[0110] In this embodiment, when the first partition 211 and the second partition 212 are in contact, the buckle 2112 and the slot 2122 engage to lock them together. This ensures that when the buckle 2112 and the slot 2122 are locked together, the first partition 211 and the second partition 212 remain in contact, reducing the probability of relative movement between the first partition 211 and the second partition 212, and also reducing the probability of the locking structure 2111 and the support structure 2121 being passively unlocked.

[0111] The buckle 2112 is disposed on the upper surface of the first partition 211, and the slot 2122 is a through slot so that the buckle 2112 can pass through the slot 2122 and the buckle part of the buckle 2112 can be engaged with the upper surface of the second partition 212. So that when the conductive component 22 is welded and the second partition 212 needs to be removed, the buckle 2112 on the upper surface of the second partition 212 can be manually moved to unlock the buckle 2112 from the slot 2122, and then the second partition 212 can be removed.

[0112] According to the embodiments of this application, by setting a buckle 2112 and a slot 2122 to cooperate, when the second partition 212 is assembled on the first partition 211, a certain limit is created on the second partition 212 and the first partition 211. That is, before the buckle 2112 and the slot 2122 are unlocked, it can be ensured that the locking structure 2111 on the first partition 211 and the support structure 2121 on the second partition 212 remain aligned and cooperated, reducing the probability of the locking structure 2111 and the support structure 2121 being passively separated, and improving the stability of the overall structure.

[0113] According to some embodiments of this application, refer to Figure 2 , Figure 5 and Figure 7 Both the first partition 211 and the second partition 212 may be provided with clearance holes 213, which may be adapted to correspond to the welding position 222 of the conductive component 22.

[0114] The welding position 222 of the conductive component 22 is the position where the conductive component 22 is welded to the terminal post of the battery cell 11. By providing clearance holes 213 on the first partition 211 and the second partition 212, the welding fixture can be inserted into the clearance holes 213 to perform welding operations on the welding position 222 of the conductive component 22 during operation.

[0115] It is understandable that multiple clearance holes 213 can be provided on the first partition 211 and the second partition 212, wherein each clearance hole 213 corresponds to a mounting position on a conductive component 22. By providing multiple clearance holes 213, the volume of a single clearance hole 213 can be reduced, the structural strength of the partition can be improved, and the positioning of welding fixtures can be facilitated.

[0116] The clearance hole 213 provided according to the embodiment of this application is to facilitate the welding operation of the welding fixture on the conductive component 22.

[0117] According to some embodiments of this application, the welding position 222 of the conductive component 22 is provided with a welding hole 223. By providing the welding hole 223, the welding fixture can weld the conductive component 22 to the electrode of the battery cell 11.

[0118] According to some embodiments of this application, refer to Figure 7 The mounting area is used to fit the conductive element 22 at least in the area surrounding the clearance hole 213, and the lower surface of the second partition 212 fits the upper surface of the first partition 211 at least in the area surrounding the clearance hole 213.

[0119] In this embodiment, the clearance hole 213 of the first partition 211 is provided in the installation area, and the lower surface of the first partition 211 is planar at least in the installation area. The upper surface of the conductive member 22, which is used to connect with the first partition 211, is planar, so that the lower surface of the first partition 211 can fit with the conductive member 22 in the area surrounding the clearance hole 213, and the gap at the junction of the clearance hole 213 of the first partition 211 and the conductive member 22 is smaller.

[0120] The lower surface of the second partition 212 is in contact with the upper surface of the first partition 211 in the area surrounding the clearance hole 213, so that the gap at the junction of the clearance hole 213 of the second partition 212 and the upper surface of the first partition 211 is smaller, thereby reducing the probability that the welding slag generated by the welding fixture during the welding of the welding position 222 of the conductive component 22 will fall into the battery 1 through the gap between the first partition 211, the second partition 212 and the conductive component 22.

[0121] In one example, refer to Figure 2 and Figure 7 The lower surface of the second partition 212 may be provided with an annular boss surrounding the clearance hole 213, and the end of the annular boss facing away from the second partition 212 is tightly sealed against the upper surface of the first partition 211.

[0122] In the above technical solution, by attaching the mounting area of ​​the first separator 211 to the surface of the conductive component 22, and attaching the second separator 212 to the first separator 211 at the position of the clearance hole 213, the gap between the first separator 211, the second separator 212 and the conductive component 22 in the clearance hole 213 area is smaller. The welding slag generated during the welding process is less likely to fall into the battery box through the first separator 211, the second separator 212 and the conductive component 22, thereby helping to improve the assembly quality of the battery 1, increase production efficiency and reduce safety risks.

[0123] According to some embodiments of this application, refer to Figures 5-8The first partition 211 may be provided with a through hole 2110 that corresponds to the mounting hole 221 of the conductive element 22. The locking structure 2111 may include an elastic protrusion 21111, which may be provided on the lower surface of the first partition 211 and surround the through hole 2110.

[0124] In this embodiment, the elastic protrusion 21111 can extend into the mounting hole 221 of the conductive member 22, and the elastic protrusion 21111 can be elastically deformable. Specifically, the elastic protrusion 21111 can be elastically deformable in the direction close to and away from the axis of the through hole 2110, so that when the elastic protrusion 21111 deforms along the axis away from the through hole 2110, it can be pressed and locked against the inner wall of the mounting hole 221, and after returning to its original state, it can be released from the mounting hole 221.

[0125] like Figure 4 and Figure 6 As shown, the support structure 2121 includes a support column 21212, which is movably disposed in the through hole 2110 between a supported position and a separated position. When the support column 21212 is moved to the supported position, it passes through the through hole 2110 and is press-fitted with at least a portion of the elastic protrusion 21111, so that the elastic protrusion 21111 opens outward and is adapted to be pressed and limited against the inner wall of the mounting hole 221.

[0126] In this embodiment, the support post 21212 is disposed on the lower surface of the second partition 212. The support post 21212 is movably disposed within the through hole 2110 in the vertical direction, allowing it to move between a supported position and a separated position. When the support post 21212 moves downward to the supported position, it penetrates the through hole 2110 and is press-fitted with at least a portion of the elastic protrusion 21111, applying a force away from the axis of the through hole 2110 to the elastic protrusion 21111. This causes the elastic protrusion 21111 to expand outward and abut against the inner wall of the mounting hole 221, thereby locking the conductive element 22. When disassembling the first partition 211, the support post 21212 is pulled upward, the elastic protrusion 21111 returns to its original position and separates from the inner wall of the mounting hole 221, releasing the lock on the conductive element 22, and the first partition 211 can be removed.

[0127] The cross-sectional shape of the through hole 2110, the shape of the elastic protrusion 21111, and the shape of the support column 21212 are matched to facilitate connection. The specific shapes are not limited here. For example, to facilitate the deformation of the elastic protrusion 21111 and reduce frictional resistance, the cross-sectional shape of the through hole 2110 can be circular, the elastic protrusion 21111 can be annular, and the support column 21212 can be cylindrical.

[0128] For example, the elastic protrusion 21111 can be made of elastically deformable rubber material with good deformation performance and high coefficient of friction, resulting in high frictional force and high mating strength after being pressed together.

[0129] The elastic protrusion 21111 and support column 21212 provided in the embodiments of this application utilize the elastic deformation property of the elastic protrusion 21111 to push the elastic protrusion 21111 outward by the support column 21212 and press it against the inner wall of the mounting hole 221 of the conductive component 22. The frictional force generated by the tight fit between the elastic protrusion 21111 and the mounting hole 221 is used to fix the conductive component 22. The structure is simple, the production cost is low, and the installation and disassembly operations are easy and the assembly efficiency is high.

[0130] According to some embodiments of this application, refer to Figure 3 and Figure 6 The elastic protrusions 21111 include multiple ones, and the multiple elastic protrusions 21111 are arranged at intervals around the through hole 2110.

[0131] In this embodiment, there can be multiple elastic protrusions 21111, and the number of elastic protrusions 21111 is not limited here; it can be three, four, or five. For example, there can be four elastic protrusions 21111, which are spaced apart and evenly distributed around the through hole 2110, so that the elastic deformation of each elastic protrusion 21111 is similar, and the clamping force is more stable.

[0132] By setting multiple elastic protrusions 21111, when the support column 21212 moves to the support position, the support column 21212 can push each individual elastic protrusion 21111 to elastically deform. Each individual elastic protrusion 21111 can be made of a material with higher hardness, such as plastic, which is not easy to fail after multiple uses, can adapt to multiple recycling of the first partition 211, has better durability, and is more stable in use.

[0133] According to the embodiments of this application, multiple elastic protrusions 21111 are provided to facilitate the independent movement of each elastic protrusion 21111 and improve the durability of a single elastic protrusion 21111.

[0134] According to some embodiments of this application, refer to Figure 6 and Figure 8 The elastic protrusion 21111 has a protrusion 21112 on one side near the axis of the through hole 2110. The protrusion 21112 is near the end of the elastic protrusion 21111 away from the first partition 211. When the support column 21212 is in the support position, it is in an interference fit with the protrusion 21112. When the support column 21212 is in the separation position, it is separated from the protrusion 21112.

[0135] It should be noted that, Figure 8The diagram does not show the outward opening of the elastic protrusion 21111. The dotted part of the protrusion 21112 in the diagram has an interference fit with the support column 21212.

[0136] In this embodiment, by providing a protrusion 21112 on the side of the elastic protrusion 21111 near the axis of the through hole 2110, and by providing the protrusion 21112 near the end of the elastic protrusion 21111 away from the first partition 211, the support column 21212 can push the protrusion 21112 to cause the end of the elastic protrusion 21111 away from the first partition 2111 to deform away from the axis of the through hole 2110 during the movement of the support column 21212 towards the support position. This results in a smaller deformation at the connection between the elastic protrusion 21111 and the first partition 211, making it less prone to damage, and ensuring that the elastic protrusion 21111 has sufficient deformation.

[0137] According to the embodiments of this application, a protrusion 21112 is provided on the elastic protrusion 21111 so that the support column 21212 can open the elastic protrusion 21111 outward when it moves to the support position.

[0138] According to some embodiments of this application, refer to Figure 6 and Figure 8 The protrusion 21112 has a guide surface 21113 on the side near the first partition 211, and the guide surface 21113 is inclined inward in a direction away from the first partition 211.

[0139] In this embodiment, by providing a guide surface 21113, the support column 21212 can first abut against the guide surface 21113 during its movement toward the support position. This is equivalent to increasing the diameter of the elastic protrusion 21111 at the corresponding end, which can reduce the requirements for machining accuracy and facilitate the insertion of the support column 21212 into the elastic protrusion 21111. The guide surface 21113 can guide the support column 21212 to move to the position where it is locked with the elastic protrusion 21111, which can reduce the wear between the support column 21212 and the protrusion 21112.

[0140] For example, the lower end of the guide surface 21113 can be connected to the through hole 2110 so that the guide surface 21113 has sufficient length, reducing the slope of the guide surface 21113, thereby reducing frictional resistance and wear.

[0141] In the above technical solution, by providing a guide surface 21113 on the protrusion 21112, the requirements for machining accuracy can be reduced. The guide surface 21113 can guide the support column 21212 to move to the position where it is locked with the elastic protrusion 21111, thereby improving assembly efficiency and reducing wear during assembly.

[0142] According to some embodiments of this application, refer to Figure 6 and Figure 8One of the outer peripheral wall of the support column 21212 and the side wall of the protrusion 21112 near the support column 21212 is provided with a limiting groove 21114 and the other is provided with a limiting protrusion 21211. When the support column 21212 moves to the support position, the limiting protrusion 21211 and the limiting groove 21114 are correspondingly engaged.

[0143] It is understandable that, because the elastic protrusion is an elastic element, during installation or transportation, the contraction force of the elastic protrusion may squeeze the support column 21212 to the separation position.

[0144] By setting a limiting groove 21114 and a limiting protrusion 21211, when the support column 21212 moves to the support position, the limiting protrusion 21211 can extend into the limiting groove 21114 to cooperate with the limiting groove 21114 for limiting, so that a certain limiting force is generated between the support column 21212 and the elastic protrusion, making it difficult for the support column 21212 to be passively separated from the elastic protrusion.

[0145] In one example, refer to Figure 6 As shown, the limiting protrusion 21211 is provided on the outer peripheral wall of the support column 21212, and the surface of the protrusion 21112 near the axis of the through hole 2110 is provided with a limiting groove 21114.

[0146] The limiting groove 21114 and the limiting protrusion 21211 provided according to the embodiments of this application are designed so that the support column 21212 has a certain limiting force when it cooperates with the elastic protrusion, and the support column 21212 is not easy to detach from the limiting protrusion 21211 on its own, thereby improving the stability of the overall structure.

[0147] According to some embodiments of this application, refer to Figure 6 and Figure 8 The support column 21212 has a chamfered edge at one end near the protrusion 21112. By providing the chamfer on the support column 21212, the resistance between the support column 21212 and the protrusion 21112 is reduced during installation, improving assembly efficiency and reducing wear during assembly. The chamfer can be either a bevel or a rounded corner.

[0148] According to some embodiments of this application, refer to Figure 6 and Figure 8The side of the elastic protrusion 21111 away from the axis of the through hole 2110 is a smooth surface 21111a. The surface roughness of the smooth surface 21111a is R3 or R2 or lower, so that the surface is relatively smooth. In this embodiment, the side of the elastic protrusion away from the axis of the through hole 2110 is clearance-fitted with the inner wall of the mounting hole 221. By making the side of the elastic protrusion away from the axis of the through hole 2110 a smooth surface 21111a, it is easier to assemble the elastic protrusion with the mounting hole 221 of the conductive component 22 and reduce wear.

[0149] Thirdly, referring to Figure 11 This application provides a method for assembling a busbar integrated component 2, wherein the busbar integrated component 2 is the busbar integrated component 2 as described in any of the above technical solutions, and will not be elaborated here.

[0150] The assembly method includes steps 310, 320, 330 and 340.

[0151] Step 310: Arrange the busbar integration assembly 2 on the upper side of multiple battery cells 11, and make the welding position 222 of the conductive component 22 correspond to the terminal post of the battery cell 11.

[0152] In this embodiment, the first separator 211 is placed on the upper side of the plurality of battery cells 11, and the lower surface of the first separator 211 is directly opposite the upper side of the plurality of battery cells 11, so that the conductive element 22 is located between the first separator 211 and the plurality of battery cells 11. At this time, the welding position 222 of the conductive element 22 is connected to the corresponding terminal of the corresponding battery cell 11.

[0153] Step 320: Weld the welding position 222 of the conductive component 22 to the terminal post of the battery cell 11;

[0154] In this embodiment, the welding fixture may have a welding head and a clamping fixture. The welding head can extend into the clearance hole 213 of the first separator 211 and weld the welding position 222 of the conductive element 22 to the terminal post of the battery cell 11. During welding, the clamping fixture presses against the upper surface of the first separator 211 and applies a downward clamping force to ensure that the conductive element 22 is in contact with the terminal post of the battery cell 11. At the same time, it can also keep the first separator 211 and the conductive element 22 pressed together. The clamping force of the clamping fixture makes the clearance hole 213 of the first separator 211 in closer contact with the surface of the conductive element 22, resulting in a better seal and reducing the risk of weld slag falling out from the gap between the conductive element 22 and the first separator 211.

[0155] Step 330: Separate the support structure 2121 from the locking structure 2111 to unlock the locking structure 2111 from the conductive element 22;

[0156] After the welding fixture is completed, the conductive component 22 is fixedly connected to the battery cell 11. The support structure 2121 is disassembled from the upper side of the first partition 211 upwards to separate the support structure 2121 from the locking structure 2111, thereby unlocking the locking structure 2111 from the conductive component 22 and unlocking the first partition 211 from the conductive component 22.

[0157] Step 340: Remove the first partition 211.

[0158] By removing the first separator 211 from the battery 1 upwards, the welding connection of the conductive component 22 and the disassembly and recycling of the first separator 211 can be completed.

[0159] According to the assembly method of the busbar integrated assembly 2 provided in the embodiments of this application, after the conductive component 22 is welded to the battery cell 11, the support structure 2121 and the locking structure 2111 are separated to unlock the locking structure 2111 from the conductive component, so that the first separator 211 can be disassembled from the battery 1, recycled and reused, thereby reducing the weight of the battery 1 and reducing the production cost.

[0160] According to some embodiments of this application, the wire harness isolation plate 21 may further include a second partition 212, which is detachably mounted on the upper surface of the first partition 211 and may have a support structure 2121. The first partition 211 may be provided with a buckle 2112 on the side near the second partition 212, and the second partition 212 may be provided with a slot 2122 at the position corresponding to the buckle 2112. When the first partition 211 and the second partition 212 are in contact, the buckle 2112 may cooperate with the slot 2122 to lock.

[0161] Step 330 may include steps 331 and 332.

[0162] Step 331: Unlock the buckle 2112 from the slot 2122;

[0163] In this embodiment, the second partition 212 covers the upper surface of the first partition 211, and the first partition 211 and the second partition 212 are fixed together by a snap fastener 2112 and a slot 2122. After the conductive component 22 is fixedly connected to the battery cell 11, the snap fastener 2112 can be pushed aside on the upper surface of the second partition 212 to unlock the snap fastener 2112 from the slot 2122, thereby disengaging the locking relationship between the second partition 212 and the first partition 211.

[0164] Step 332: Separate the second partition 212 from the first partition 211 to separate the support structure 2121 from the locking structure 2111.

[0165] After the locking relationship between the second partition 212 and the first partition 211 is released, the second partition 212 can be taken out of the battery 1 upwards. During the removal process, the second partition 212 causes the multiple support structures 2121 set on it to separate and unlock from the multiple locking structures 2111 on the first partition 211.

[0166] According to the assembly method of this application embodiment, the second partition 212 drives multiple support structures 2121 to move simultaneously, resulting in higher unlocking efficiency. By setting buckles 2112 and slots 2122, the assembly stability of the first partition 211 and the second partition 212 is improved. Before disassembly and recycling, the buckles 2112 and slots 2122 can be unlocked. The assembly process is simple, quick, and highly stable.

[0167] According to some embodiments of this application, see Figures 1-10 As shown, this application provides a busbar integrated assembly 2, which includes a wire harness isolation plate 21, a conductive component 22, an FPC, and an NTC component 23.

[0168] The wire harness isolation plate 21 includes a first partition 211 and a second partition 212.

[0169] The lower surface of the first partition 211 is provided with an installation area, and the conductive component 22 is installed in the installation area. The conductive component 22 is provided with an installation hole 221. The installation area of ​​the first partition 211 is provided with a through hole 2110 corresponding to the installation hole 221. The installation area is provided with an elastic protrusion 21111 extending in a direction away from the first partition 211. The elastic protrusion 21111 includes a plurality of protrusions spaced around the through hole 2110. The elastic protrusion 21111 extends into the installation hole 221 and is provided with a clearance fit with the installation hole 221.

[0170] The second partition 212 covers the upper surface of the first partition 211. The lower surface of the second partition 212 is provided with a support column 21212. The second partition 212 drives the support column 21212 to be movably installed in the through hole 2110. When it is moved to the support position, the support column 21212 passes through the through hole 2110 and pushes the elastic protrusion 21111 away from the axis of the through hole 2110, so that the side wall of the elastic protrusion 21111 away from the axis of the through hole 2110 abuts against the inner wall of the mounting hole 221 and limits it. When it is moved to the separation position, the support column 21212 separates from the elastic protrusion 21111, and the elastic protrusion 21111 returns to its original position.

[0171] The elastic protrusion 21111 has a protrusion 21112 on the side near the axis of the through hole 2110. The protrusion 21112 has a guide surface 21113 on the side near the first partition 211. The guide surface 21113 is inclined inward in a direction away from the first partition 211. The protrusion 21112 has a limiting groove 21114 on the side wall near the support column 21212. The outer peripheral wall of the support column 21212 has a limiting protrusion 21211. When the support column 21212 moves to the support position, the limiting protrusion 21211 cooperates with the limiting groove 21114 to limit the position. The end of the support column 21212 near the protrusion 21112 has a chamfer.

[0172] The conductive element 22 is provided in multiple ways, and each conductive element 22 is provided with at least two mounting holes 221. The first partition 211 is provided with multiple elastic protrusions, and the multiple elastic protrusions correspond to the multiple mounting holes 221. The second partition 212 is provided with multiple support columns 21212 corresponding to the multiple elastic protrusions.

[0173] The first partition 211 and the second partition 212 are respectively provided with a plurality of corresponding clearance holes 213, and the conductive component 22 is provided with at least two welding positions 222. The plurality of clearance holes 213 of the first partition 211 and the second partition 212 correspond to the plurality of welding positions 222. The mounting area of ​​the first partition 211 is in contact with the conductive component 22 at least in the area surrounding the clearance holes 213, and the lower surface of the second partition 212 is in contact with the upper surface of the first partition 211 at least in the area surrounding the clearance holes 213.

[0174] The first partition 211 is provided with a positioning hole 2113, and the lower surface of the second partition 212 is provided with a positioning pin 2123. When the second partition 212 is in contact with the first partition 211, the positioning pin 2123 extends into the positioning hole 2113 for positioning and engagement.
