Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electrical engineering, concretely is a kind of fixed tool for integrated busbar. BACKGROUND

[0002] At present, the demand for battery pack lightweight of new energy vehicles and energy storage systems continues to rise, and carrier-free integrated busbar becomes the mainstream trend.Compared with traditional busbar with PC, plastic or PET film carrier, carrier-free integrated busbar significantly reduces weight and thermal resistance, reduces cost while improving overall temperature resistance of battery pack, and becomes an important direction of industry technology upgrading.However, due to the lack of rigid carrier, such busbar needs to rely on external fixtures for stable positioning during assembly, welding and testing.The existing fixing tool in the market is mostly integrated or simply divided into two parts, and its design concept still stays at the stage of adapting to traditional busbar with carrier, which cannot meet the lightweight and flexible assembly requirements of carrier-free busbar.

[0003] To solve the above problems, a lightweight, modular and highly adaptable fixing tool is needed.The present application decouples the tool into head, middle and tail structure blocks that can be freely assembled through segmented design, and combines mortise coupling mechanism with lightweight materials to significantly reduce the self-weight of the tool while achieving quick adaptation of length and electrode arrangement, thus achieving the characteristics of reducing self-weight, easy to carry, improving rigidity and reducing damaged molds.The modular architecture not only compresses the storage volume, but also can be flexibly expanded by adding or reducing middle modules to cooperate with edge limiting strips and positioning grooves, so that the assembly method of the fixing tool can be adjusted according to actual needs to ensure the global stable constraint and high-precision positioning of carrier-free busbar under the lightweight target, providing technical support for efficient assembly and reliable operation of battery pack.

[0004] After searching, the patent literature discloses a collection lead and tab fixing device, battery module integrated busbar and battery module

application number: 202323443412.6, publication number: CN222546603U

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a fixing tool for integrated busbar.

[0006] The utility model provides a kind of integrated busbar fixing tool, it is characterized in that, including head structure block, tail structure block and several middle structure blocks, middle structure block can be connected to constitute a whole in head and tail;

[0007] One end of the whole constituted by middle structure block is equipped with head structure block, and the other end of the whole constituted by middle structure block is equipped with tail structure block.

[0008] Preferably, the top of the head structure block is provided with a short side limiting strip, and the two sides of the head structure block are provided with a long side limiting strip.

[0009] Through the above technical solution, the limiting strips on the top and both sides of the head structure block can effectively limit the movement of the integrated busbar in the tool, preventing it from shifting or displacing. This design ensures that the integrated busbar is always in the correct position during fixing, avoiding poor contact or electrical failure caused by inaccurate position. At the same time, the setting of the limiting strips enhances the adaptability between the tool and the integrated busbar, improving the reliability and stability of the tool. In addition, the limiting strip design of the head structure block, by reasonably distributing limiting edges of different lengths, can accommodate integrated busbars of different sizes and shapes, enhancing the versatility of the tool.

[0010] Preferably, the top of the tail structure block is provided with a short side limiting strip, and the two sides of the tail structure block are provided with a long side limiting strip.

[0011] Through the above technical solution, the short side limiting strip and the long side limiting strip of the tail structure block can effectively position and fix the integrated busbar. The short side limiting strip plays a positioning role at the tail, ensuring that the integrated busbar does not move forward and backward in the tool. The long side limiting strip helps to limit the left and right deviation of the integrated busbar in the tail area, ensuring the correct position of the integrated busbar and avoiding poor contact or electrical performance degradation caused by deviation. This design of the tail structure block not only enhances the stability of the integrated busbar, but also improves the operability of the overall tool during assembly.

[0012] Preferably, the head structure block, the tail structure block and the middle structure block are connected through connecting rods with grooves and connecting holes.

[0013] By the above technical solution, the connecting rod with a groove not only simplifies the assembly process, but also avoids the difficulty of plugging caused by air pressure difference. During the use of the tooling, the internal air pressure difference may affect the connection between the structure blocks, leading to excessive tightening or hindering disassembly. The connecting rod with a groove can balance the air pressure difference by providing a natural space, making it easier to insert or pull out. In addition, this design enhances the stability and accuracy of the connection. The shape of the groove allows the connecting rod to be better aligned and stably positioned when inserted, ensuring the tight connection between the structure blocks and avoiding unnecessary looseness or misalignment. The design of the connecting rod not only improves the overall strength of the connection, but also makes the assembly of the tooling more convenient and fast. The installer only needs to align and insert the structure blocks into the corresponding tenon and connecting rod to complete the assembly of the tooling, without the need for complex tools or excessive steps, thereby greatly improving work efficiency.

[0014] Preferably, the head structure block is in a concave structure, the tail structure block is in a convex structure, and the side of the middle structure block close to the head structure block is in a convex structure, and the side of the middle structure block close to the tail structure block is in a concave structure.

[0015] By the above technical solution, this design fully utilizes the butt joint characteristics of concave-convex shapes to achieve accurate butt joint and firm connection between structure blocks. Specifically, the convex and concave design between the head structure block and the middle structure block ensures that they can better combine together, preventing looseness or misalignment during use. The concave design of the side of the middle structure block close to the tail and the convex design of the tail structure block cooperate to allow the tail structure block to be stably embedded in the middle structure block, forming a stable overall structure. Such concave-convex cooperation can increase the connection area between each structure block, thereby improving the stability and strength of the tooling and ensuring its durability in long-term use. This design also helps to simplify the assembly process, as each structure block has a clear shape cooperation, which can ensure accurate butt joint without the need for additional tools or complex adjustments, reducing the difficulty of assembly and improving production efficiency.

[0016] Preferably, holes are provided on the head structure block, the tail structure block and the middle structure block, and the positions of the holes correspond to the positions of the integrated female aluminum bars.

[0017] Through the technical scheme, the accuracy and reliability in the installation process can be ensured, the holes can ensure that the tool and the integrated busbar are perfectly matched, so that the integrated busbar can be fixed in the predetermined position during the installation of the fixing tool. The accurate positioning reduces human errors in the assembly process, ensures the stability and efficiency of the electrical connection, and in addition, the position of the hole and the butt joint design of the aluminum bar make the integrated busbar more firmly fixed in the tool, avoiding poor contact or electrical performance problems caused by misalignment or improper installation.

[0018] Preferably, the head structure block, the tail structure block and the middle structure block are provided with a side edge facing the integrated busbar, and the shape of the edge is matched with the integrated busbar.

[0019] Through the technical scheme, the tool can be accurately matched with the integrated busbar, and each part of the tool is perfectly matched with the shape and size of the integrated busbar, thereby providing a more stable fixing effect. The edge design not only enhances the stability of the integrated busbar, but also effectively prevents deviation or loosening during installation. Since the shape of the edge is perfectly matched with the integrated busbar, it can provide uniform pressure during installation, ensuring that the electrical connection of each contact point of the integrated busbar is uniform and stable. This not only improves the stability of the overall tool, but also optimizes the accuracy of the installation process, reducing poor contact caused by improper positioning.

[0020] Preferably, the head structure block, the tail structure block and the middle structure block are provided with a side edge facing the integrated busbar, and the shape of the edge is matched with the integrated busbar.

[0021] Through the technical scheme, the middle part of the head structure block, the tail structure block and the middle structure block is provided with a positioning groove, and when the head structure block, the tail structure block and the middle structure block form an integral whole, the positioning grooves are in a straight line.

[0021] Through the technical scheme, the middle part of the head structure block, the tail structure block and the middle structure block is provided with a positioning groove, and when the head structure block, the tail structure block and the middle structure block form an integral whole, the positioning grooves are in a straight line.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] 1. The integrated busbar fixing tool adopts a structure connection design, combines a connecting rod with a groove and a precisely positioned structure block, realizes stable butt joint between parts, and ensures that the structure blocks are accurately aligned during installation, avoids poor contact or loosening caused by improper connection, and improves the stability and reliability of the overall tool.

[0024] 2. The integrated busbar fixing tool optimizes the insertion and removal process through the grooved connecting rod. The design of the grooves effectively avoids installation difficulties caused by air pressure differences, allowing the installer to quickly and easily assemble and disassemble the tool, greatly improving work efficiency and reducing human error or damage during operation.

[0025] 3. The integrated busbar fixing tool has a strong versatility in its structural design, allowing it to adapt to various models of integrated busbars. The adaptive design of the head, tail, and middle structural blocks enables the tool to flexibly handle busbars of different sizes and shapes, reducing the need for frequent tool replacement or adjustment due to model changes. This not only saves production and maintenance costs but also improves the tool's adaptability in different application scenarios. BRIEF DESCRIPTION OF DRAWINGS
