Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a busbar structure. This utility model also relates to a battery pack having the above-mentioned busbar structure. Background Technology

[0002] With the rapid development of new energy battery technology, the reliability and maintainability of the busbar structure in battery modules have become key factors affecting the overall performance of the battery pack. Traditional busbar structures typically include a slave board for the battery management system, used to collect operating parameters and other information from each cell to ensure the normal operation of the battery pack. In existing technologies, this slave board is usually fixed to the busbar support by hot-riveting posts or other rigid fixing methods. However, if it is necessary to remove the slave board separately from the busbar support, the hot-riveting posts on the busbar support must be destructively removed, but the removed hot-riveting posts cannot be used to re-fix the slave board.

[0003] Therefore, when it is necessary to replace the slave board or repair the busbar structure, the slave board cannot be replaced alone; the entire busbar structure must be replaced. The replacement process is complicated and increases maintenance costs, which is not conducive to the inspection and maintenance of the battery pack. Utility Model Content

[0004] In view of this, the present invention aims to provide a busbar structure to facilitate the disassembly and replacement of the busbar.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A busbar structure includes a busbar support, a slave plate support disposed on the busbar support, and a slave plate disposed on the slave plate support;

[0007] The busbar support is provided with a guide part and a snap-fit ​​part, and the slave plate support is provided with a guide fitting part that slides with the guide part and a snap-fit ​​fitting part that matches the snap-fit ​​part.

[0008] The guide portion and the guide mating portion can guide the slave plate bracket to slide relative to the busbar bracket along a first direction;

[0009] As the slave plate bracket slides relative to the busbar bracket, the slave plate bracket can be connected to the busbar bracket through the snap-fit ​​engagement of the snap-fit ​​part and the snap-fit ​​mating part.

[0010] Furthermore, the guide portion includes a guide rib extending along the first direction, and the guide mating portion includes a groove, which is capable of sliding on the guide rib.

[0011] Furthermore, the busbar support is also provided with a flexible circuit board, which has a connection portion for electrical connection with the slave board; the guide rib is provided with a first notch, and the connection portion can pass through the first notch and pass through the busbar support and the slave board support in a second direction.

[0012] Furthermore, the slave plate support is provided with a second notch, which is located at a position corresponding to the first notch; the connecting part can pass through the second notch and fold to the side of the slave plate support where the slave plate is located.

[0013] Furthermore, the snap-fit ​​portion includes a first snap fastener disposed on the busbar support, and the snap-fit ​​mating portion includes a snap-fit ​​seat structure disposed on the slave plate support, wherein the first snap fastener can be hooked onto the snap-fit ​​seat structure.

[0014] Furthermore, the first buckle and the bracket structure are respectively disposed on two opposite sides of the busbar support and the slave plate support, and the slave plate support is formed with a clearance groove for avoiding the buckle; as the slave plate support slides relative to the busbar support, the first buckle can move along the clearance groove and hook into the bracket structure.

[0015] Furthermore, the slave plate bracket is provided with a mounting groove, and the mounting groove is provided with a snap-fit ​​structure, which can snap and fix the slave plate in the mounting groove.

[0016] Furthermore, the snap-fit ​​structure includes a plurality of second snaps and / or a plurality of snap-fit ​​ribs arranged opposite to each other on the inner wall of the mounting groove; each of the second snaps snaps onto both ends of the plate in the length direction, and each of the snap-fit ​​ribs snaps onto both ends of the plate in the width direction.

[0017] Furthermore, the mounting groove is also provided with a plurality of reinforcing ribs arranged in a cross pattern. When the slave plate is snapped into the mounting groove, the slave plate can abut against each of the reinforcing ribs.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] The busbar structure described in this utility model, through the setting of the guide part and the guide engagement part, as well as the snap-fit ​​part and the snap-fit ​​engagement part, allows the slave plate bracket to be guided to slide relative to the busbar bracket in a first direction. When the slave plate bracket slides to a preset position, the slave plate bracket can snap-fit ​​with the busbar bracket, realizing the detachable connection between the slave plate bracket and the busbar bracket, so as to facilitate the disassembly and replacement of the slave plate, thereby facilitating the inspection and maintenance of the battery pack.

[0020] In addition, the guide section includes guide ribs, and the guide mating section includes a sliding groove. The sliding groove can slide on the guide ribs to guide the slave board bracket, facilitating the assembly and disassembly of the slave board bracket. The guide ribs have a first notch, which provides space for the connection portion of the flexible circuit board, allowing the connection portion to be clamped between the slave board bracket and the busbar bracket, thereby improving the fixation effect of the flexible circuit board. Simultaneously, the slave board bracket has a second notch, which provides space for the folding of the connection portion, facilitating its connection with the slave board.

[0021] In addition, the snap-fit ​​part includes a first snap-fit, and the snap-fit ​​mating part includes a snap-fit ​​seat structure. When the plate bracket slides, it can drive the first snap-fit ​​into the snap-fit ​​seat structure, which has a better connection effect and facilitates the connection between the plate bracket and the busbar bracket. The first snap-fit ​​and the snap-fit ​​seat structure are located on two opposite sides between the plate bracket and the busbar bracket to reduce the space occupied by other parts of the busbar bracket. At the same time, the plate bracket is provided with a clearance groove to prevent the first snap-fit ​​from interfering with the plate bracket.

[0022] Furthermore, the mounting plate bracket is equipped with a mounting groove, and the slave plate is snapped into the mounting groove via a snap-fit ​​structure, providing installation space and facilitating the installation of the slave plate. The snap-fit ​​structure includes multiple second snaps and multiple snap-fit ​​ribs, which can fix the slave plate in both the first and second directions, improving the fixation effect of the slave plate. Reinforcing ribs inside the mounting groove abut against the slave plate and provide support, preventing wear and collision between the slave plate and the mounting groove.

[0023] Another objective of this invention is to provide a battery pack. The battery pack has a busbar structure as described above.

[0024] The battery pack and / or busbar structure described in this utility model have the same technical effects as the prior art, and will not be described in detail here. Attached Figure Description

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Example 1

[0043] In the prior art, the slave plate 3 is usually rigidly fixed to the busbar bracket 1 by means of hot riveting or other methods. When it is necessary to maintain the busbar structure or replace the slave plate 3, the slave plate 3 cannot be removed separately, and the entire busbar structure can only be replaced.

[0044] Therefore, this embodiment relates to a busbar structure, the overall structure of which is as follows: Figure 1 , Figure 2 As shown, this embodiment includes a busbar support 1, a slave plate support 2 disposed on the busbar support 1, and a slave plate 3 disposed on the slave plate support 2.

[0045] The busbar support 1 has a guide portion and a locking portion, and the slave plate support 2 has a corresponding guide engagement portion that slides with the guide portion and a locking engagement portion that matches the locking portion. The guide portion and the guide engagement portion can guide the slave plate support 2 to slide relative to the busbar support 1 along a first direction. Furthermore, as the slave plate support 2 slides relative to the busbar support 1, the slave plate support 2 can be connected to the busbar support 1 through the locking engagement of the locking portion and the locking engagement portion.

[0046] As configured above, through the setting of the guide part and the guide engagement part, as well as the snap-fit ​​part and the snap-fit ​​engagement part, the slave plate bracket 2 can be guided to slide relative to the busbar bracket 1 in the first direction. When the slave plate bracket 2 slides to the preset position, the slave plate bracket 2 can snap-fit ​​with the busbar bracket 1, realizing the detachable connection between the slave plate bracket 2 and the busbar bracket 1, so as to facilitate the disassembly and replacement of the slave plate 3, thereby facilitating the inspection and maintenance of the battery pack.

[0047] Based on the above overall introduction, specifically, in this embodiment, the busbar structure is located at the end of the battery module where the terminal posts are located, and the busbar bracket 1 is provided with multiple busbars 7 for connecting each battery cell. For example... Figure 1 , Figure 3 As shown, the busbar 7 is installed in the mounting holes 8 on the busbar bracket 1. An explosion-proof valve is provided at the end of the battery cell to prevent it from exploding due to excessive internal pressure in the event of thermal runaway. To prevent the busbar bracket 1 from obstructing the opening of the explosion-proof valve, the busbar bracket 1 in this embodiment is also provided with multiple clearance holes 9 corresponding one-to-one with the battery cell explosion-proof valves. Furthermore, the first direction described in this embodiment is the length direction of the busbar bracket 1, which is the arrangement direction of each battery cell, and the second direction described below is the width direction of the busbar bracket 1. The busbar 7 and the clearance holes 9 are respectively located at both ends of the busbar bracket 1 along the width direction.

[0048] As a specific form of implementation, such as Figure 2 , Figure 3 and Figure 5 As shown, the guide portion of this embodiment includes a guide rib 101 extending along a first direction, and the guide mating portion includes a slide groove 201, which can slide on the guide rib 101. Through the mating arrangement of the guide rib 101 and the slide groove 201, the structure is simple and reliable. The plate bracket 2 can smoothly slide on the busbar bracket 1 through the sliding guidance effect of the slide groove 201 on the guide rib 101, thereby facilitating the assembly and disassembly of the plate bracket 2.

[0049] In practical implementation, the guide rib 101 of this embodiment has a "T"-shaped cross-section, which can constrain the slide groove 201, i.e., the plate bracket 2, in the second direction and in the direction perpendicular to the surface of the busbar bracket 1, thus having a high fixing effect. Furthermore, the guide rib 101 and the slide groove 201 of this embodiment can be configured as multiple corresponding pairs to further improve the connection strength of the plate bracket 2 installed on the busbar bracket 1.

[0050] Based on this, as a specific implementation, the busbar support 1 is provided with two connecting plates 102 arranged at intervals along the second direction, and the aforementioned guide ribs 101 are respectively provided on the opposite sides of the two connecting plates 102. Simultaneously, the sliding grooves 201 on the slave plate support 2 are also configured on the two end faces of the slave plate support 2 in the second direction. The connecting plates 102 can form a limiting constraint on the slave plate support 2 in the second direction, improving the fixing effect of the slave plate support 2 in the second direction.

[0051] Of course, the guide ribs 101 in this embodiment can be directly set on the busbar support 1, and can be configured as multiple ones spaced apart along the second direction. At the same time, the guide part in this embodiment can also be set as the slide groove 201 mentioned above, and the guide mating part can be set as the guide ribs 101 mentioned above, which can ensure that the slave plate support 2 can be guided and slide relative to the slave plate support 2.

[0052] In this embodiment, the busbar support 1 is also provided with a flexible circuit board 4, which can be electrically connected to each busbar 7 and monitor the operating temperature of each battery cell. The flexible circuit board 4 has a connecting portion 401 for electrical connection with the slave board 3. Simultaneously, the guide rib 101 has a first notch 5, through which the connecting portion 401 can pass and be positioned between the busbar support 1 and the slave board support 2 along a second direction. The first notch 5 provides space for the connecting portion 401 of the flexible circuit board 4, allowing it to be clamped between the slave board support 2 and the busbar support 1, preventing the flexible circuit board 4 from shaking due to external forces and improving its fixation effect.

[0053] In specific implementation, the connecting plate 102 used for setting the guide rib 101 in this embodiment is configured into two parts in the first direction, and the interval between the two parts corresponds to the first notch 5, which further facilitates the setting of the connecting part 401 and avoids interference between the connecting plate 102 and the connecting part 401. At the same time, the aforementioned first notch 5 is formed at both the guide rib 101 and the connecting plate 102 in the second direction.

[0054] Furthermore, in this embodiment, the slave plate support 2 is provided with a second notch 6, which is located at the position corresponding to the first notch 5. The connecting part 401 can pass through the second notch 6 and fold over to the side of the slave plate support 2 where the slave plate 3 is located. It can be understood that the connecting part 401 is sandwiched between the slave plate support 2 and the busbar support 1, and the end of the connecting part 401 needs to be folded towards the side of the slave plate support 2 where the slave plate 3 is located to be electrically connected to the slave plate 3. Thus, by providing the second notch 6 at the position of the connecting part 401 on the slave plate support 2, the second notch 6 can reduce the thickness of the edge of the slave plate support 2, reduce the bending degree of the end of the connecting part 401, and provide additional arrangement space for the connecting part 401, thereby facilitating the connection between the connecting part 401 and the slave plate 3.

[0055] In a specific implementation, the slide groove 201 on the plate support 2 is divided into two parts along the first direction, and the second notch 6 is formed between the two parts. The second notch 6 corresponds to the first notch 5 to prevent the sliding fit between the slide groove 201 and the guide rib 101 from affecting the arrangement of the connecting part 401.

[0056] As a specific form of implementation, such as Figure 2 , Figure 3 and Figure 7 As shown, the snap-fit ​​part of this embodiment includes a first snap-fit ​​103 disposed on the busbar support 1, and the snap-fit ​​mating part includes a snap-fit ​​seat structure 202 disposed on the slave plate support 2. The first snap-fit ​​103 can hook onto the snap-fit ​​seat structure 202. Through the cooperation between the first snap-fit ​​103 and the snap-fit ​​seat structure 202, when the slave plate support 2 slides along the first direction, the first snap-fit ​​103 can be driven to snap into the snap-fit ​​seat structure 202, which has a better connection effect. Furthermore, through the cooperation between the first snap-fit ​​103 and the snap-fit ​​seat structure 202, no tools are needed during assembly, which can improve the assembly speed to a certain extent. At the same time, when the first snap-fit ​​103 snaps into the snap-fit ​​seat, the elastic deformation of the first snap-fit ​​103 can generate sound and sudden change in resistance, thereby providing a confirmation signal that the assembly is in place and avoiding the risk that the slave plate support 2 is not assembled in place.

[0057] In specific implementation, such as Figure 4 As shown, the first latch 103 in this embodiment has an "L"-shaped structure, and a latching protrusion 1031 extending in the second direction is formed on the lateral portion of the "L"-shaped structure. The latching protrusion 1031 has guide surfaces on both sides in the first direction to facilitate the detachable connection between the first latch 103 and the latching structure 202, thus facilitating disassembly and installation from the plate bracket 2. Additionally, as... Figure 8 As shown, the card holder structure 202 of this embodiment includes a through hole 2021 formed on the slave plate bracket 2 and a snap-fit ​​rib 2022 extending along the second direction. The snap-fit ​​protrusion 1031 on the first buckle 103 can be hooked on the snap-fit ​​rib 2022. At the same time, when the slave plate bracket 2 is not equipped with the slave plate 3, the first buckle 103 can be observed through the through hole 2021 to see whether it is snapped in place, thereby realizing the connection between the first buckle 103 and the card holder structure 202.

[0058] Of course, the card holder structure 202 in this embodiment can also be set to other structural forms, such as card slots, which can hook the first buckle 103 to realize the connection between the card holder structure 202 and the first buckle 103.

[0059] In this embodiment, the first latch 103 and the latching structure 202 are respectively disposed on two opposite sides of the busbar support 1 and the slave plate support 2, and the slave plate support 2 has a clearance groove 203 for avoiding the latch. As the slave plate support 2 slides relative to the busbar support 1, the first latch 103 can move along the clearance groove 203 and hook into the latching structure 202. Disposing the first latch 103 and the latching structure 202 between the opposite sides of the busbar support 1 and the slave plate support 2 avoids placing the first latch 103 and the latching structure 202 on the outside of the slave plate support 2, thus occupying other functional areas of the busbar support 1, reducing space occupation, and improving structural compactness. At the same time, the first latch 103 and the latching structure 202 being disposed between the slave plate support 2 and the busbar support 1 can prevent the first latch 103 from being damaged by bumps during assembly. Furthermore, since the first buckle 103 is located on the busbar support 1 and protrudes outward, the setting of the clearance groove 203 can prevent interference between the busbar support 2 and the first buckle 103.

[0060] In practical implementation, the first buckle 103, the bracket structure 202, and the clearance groove 203 of this embodiment are configured in multiple ways. The first buckle 103 and the bracket structure 202 are respectively disposed at both ends of the slave plate bracket 2 in the first direction, and the first buckle 103, the bracket structure 202, and the clearance grooves 203 corresponding to the bracket structure 202 are staggered in the second direction. By increasing the number of first buckles 103 and bracket structures 202, the connection and fixing effect between the slave plate bracket 2 and the busbar bracket 1 can be improved.

[0061] To facilitate fixing the slave plate 3 to the slave plate bracket 2, such as Figure 6 As shown, the slave plate bracket 2 in this embodiment is provided with a mounting groove 204, and a snap-fit ​​structure is provided within the mounting groove 204. The snap-fit ​​structure can snap and fix the slave plate 3 in the mounting groove 204. The mounting groove 204 provides mounting space for the slave plate 3. The slave plate 3 is installed in the mounting groove 204, which can constrain the position of the slave plate 3 in the first and second directions. Furthermore, the higher edge of the mounting groove 204 on the side of the slave plate 3 facing outward can protect the slave plate 3 and prevent the side of the slave plate 3 from being bumped or knocked. At the same time, the snap-fit ​​structure makes the slave plate 3 easy to assemble and allows for repeated assembly and disassembly, providing a good fixing effect.

[0062] In specific implementation, the slide groove 201 of this embodiment is provided on the upper and lower edges of the mounting groove 204, and the second notch 6 is also provided on the edge of the mounting groove 204 to facilitate the connection of the connecting part 401 to the slave plate 3. Furthermore, the mounting groove is provided with the second notch 6 on both the upper and lower edges in the second direction to facilitate the connection of the connecting part 401 to the slave plate 3 at the upper and lower ends in the second direction, thereby improving the flexibility of the connection of the connecting part 401.

[0063] The slide groove 201 on the plate bracket 2 has an opening at the first end in the installation direction for inserting the guide rib 101, while the other end of the slide groove 201 is closed. When the plate bracket 2 slides on the busbar bracket 1 along the first direction, since the other end of the slide groove 201 is closed, when the plate bracket 2 slides to a predetermined position on the busbar bracket 1, the closed end of the slide groove 201 can abut against the end of the guide rib 101 to limit further sliding of the plate bracket 2, thereby achieving a limiting effect.

[0064] Specifically, the snap-fit ​​structure of this embodiment includes a plurality of second snaps 2041 and / or a plurality of snap-fit ​​ribs 2042 arranged opposite to each other on the inner wall of the mounting groove 204. Each second snap 2041 snaps onto both ends of the plate 3 along its length, and each snap-fit ​​rib 2042 snaps onto both ends of the plate 3 along its width. In a specific implementation, the inner wall of the mounting groove 204 is provided with second snaps 2041 and snap-fit ​​ribs 2042. Simultaneously, the second snaps 2041 are distributed at both ends of the mounting groove 204 along a first direction, and the second snaps 2041 at any end are configured as two spaced apart, so that each second snap 2041 can fix and constrain the four corners of the plate 3. The ends of the second snaps 2041 are formed with guide surfaces to facilitate the assembly of the plate 3. Furthermore, the snap-fit ​​ribs 2042 are provided in the mounting groove 204 along a second direction, and can fix the upper and lower ends of the plate 3 in the second direction. With the second buckle 2041 and the snap-fit ​​rib 2042, the structure is simple and reliable. It can constrain and fix the slave plate 3 in the first and second directions, preventing the slave plate 3 from falling out of the mounting groove 204. The assembly operation of the slave plate 3 can be completed by pressing the slave plate 3 into the mounting groove 204.

[0065] Finally, the mounting groove 204 in this embodiment is also provided with a plurality of cross-arranged reinforcing ribs 2043. The reinforcing ribs 2043 improve the overall structural strength of the mounting groove 204, i.e., the plate bracket 2, and prevent deformation of the plate bracket 2. When the plate 3 is snapped into the mounting groove 204, the plate 3 can abut against each reinforcing rib 2043. Through the abutment between the plate 3 and the reinforcing ribs 2043, the reinforcing ribs 2043 can provide support for the plate 3, prevent the plate 3 from shaking in the mounting groove 204, and prevent the electronic components located on the rear side of the plate 3 from being worn or bumped against the mounting groove 204, further improving the protection effect of the plate 3.

[0066] In summary, the busbar structure of this embodiment, through the provision of the guide part and the guide engagement part, as well as the snap-fit ​​part and the snap-fit ​​engagement part, allows the plate bracket 2 to be guided to slide relative to the busbar bracket 1 in the first direction. When the plate bracket 2 slides to the preset position, the plate bracket 2 can snap-fit ​​with the busbar bracket 1, realizing the detachable connection between the plate bracket 2 and the busbar bracket 1, so as to facilitate the disassembly and replacement of the plate 3, thereby facilitating the inspection and maintenance of the battery pack.
