Description
Technical Field
[0001] This invention belongs to the field of new energy battery device technology, specifically relating to an integrated busbar and module for battery pack assembly. Background Technology
[0002] With the rapid development of new energy technologies, especially their widespread application in electric vehicles and energy storage systems, the performance and assembly efficiency of battery modules have become key considerations. Battery modules are typically composed of multiple individual battery cells (such as pouch cells) connected in series and parallel to achieve the required voltage, capacity, and power output. In this process, how to efficiently, reliably, and compactly integrate multiple battery cells into a stable module is one of the core technological challenges in battery system design.
[0003] Currently, traditional battery pack assembly methods mainly have the following problems:
[0004] The assembly process is cumbersome and inefficient: In existing technologies, individual cells are typically placed one by one into a fixed battery compartment or bracket, and then mechanically secured and electrically connected using additional straps, bolts, or welding. This process involves many steps and is complex, not only time-consuming to assemble but also requiring highly skilled operators, making it difficult to achieve automated mass production and impacting overall production efficiency and cost control.
[0005] Insufficient space utilization and structural compactness: To facilitate battery placement and fixation, traditional battery compartments or support structures are often designed to be relatively spacious or contain numerous non-functional gaps. When integrating multiple battery cells into a module, these gaps result in a bulky module and reduced energy density. Although some staggered placement designs attempt to improve space utilization, they typically lack effective linkage and integration mechanisms, making the assembled structure less compact.
[0006] Positioning and locking reliability issues during assembly: Ensuring accurate positioning and reliable connection of each battery cell is crucial during battery placement and subsequent module integration. Current methods often rely on multiple independent steps and components for battery compartment expansion and folding, as well as final module locking, lacking an integrated, linked locking mechanism. This can lead to poor assembly consistency, thus affecting the long-term safety and reliability of the module.
[0007] Therefore, there is an urgent need for a new type of integrated busbar and module for battery pack assembly, which can highly integrate functions such as battery positioning, unfolding and placement, packing, mechanical locking and electrical connection, thereby simplifying the assembly process, improving production efficiency, optimizing spatial layout, enhancing pack reliability and adapting to the needs of modern and automated production. Summary of the Invention
[0008] To address the problems mentioned in the background section, this invention provides an integrated busbar and module for battery pack assembly, which enhances the reliability of battery pack assembly.
[0009] To achieve the above objectives, the present invention provides the following technical solution:
[0010] In a first aspect, the present invention provides an integrated busbar for battery pack assembly, comprising a busbar chassis assembly and battery packs. A first movable arm assembly and a second movable arm assembly are slidably disposed on both sides of the busbar chassis assembly. A first packing arm assembly and a second packing arm assembly are rotatably disposed on the first movable arm assembly and the second movable arm assembly, respectively. By tilting and swinging the first packing arm assembly on the first movable arm assembly, a staggered stacked structure of multiple battery packs is formed on the first packing arm assembly. By vertically swinging the first packing arm assembly on the first movable arm assembly, a longitudinally grouped arrangement of multiple battery packs is formed on the first packing arm assembly. The structure includes a unidirectional locking gear module on the busbar chassis assembly that drives the first moving arm assembly and the second moving arm assembly to move closer and closer synchronously. Through the synchronous movement of the first moving arm assembly and the second moving arm assembly on the busbar chassis assembly, the first group arm assembly on the first moving arm assembly and the second group arm assembly on the second moving arm assembly form a staggered and interlocked battery group structure on the busbar chassis assembly. A locking arm assembly for swinging and locking the first group arm assembly is provided at the bottom of the outer side of the first moving arm assembly, and a busbar connecting arm assembly for connecting multiple battery groups with flexible wires is provided at the top of the outer side of the first moving arm assembly.

The structure of the second packing arm assembly is the same as that of the first packing arm assembly.
[0015] The battery assembly includes a pouch cell, and one end of the pouch cell is provided with a battery connector.
[0016] In a preferred embodiment of an integrated busbar for battery pack assembly, the locking arm assembly includes a locking shaft, a locking collar is sleeved on the locking shaft, a tightening spring is sleeved and fixed between the locking collar and the locking shaft, and a pin is fixedly provided on the locking collar.
[0017] The busbar arm assembly includes an electrical connection vertical arm, on which multiple electrical connection sockets are fixedly installed. At the bottom of the electrical connection vertical arm, there is a contact disc and an electrical connection flexible wire. Both sides of the contact disc are provided with disc protrusions.
[0018] In a preferred embodiment of an integrated busbar for battery pack assembly, when the first moving arm assembly slides on the busbar chassis assembly, the guide slider slides in the side sliding groove, and at this time the roller rolls on the top surface of the U-shaped chassis. The connection method of the second moving arm assembly on the busbar chassis assembly is the same as the connection method of the first moving arm assembly on the busbar chassis assembly. The two toothed arms on the first moving arm assembly and the second moving arm assembly are respectively meshed on both sides of the toothed wheel.
[0019] In a preferred embodiment of an integrated busbar for battery pack assembly, the bottom arms of the first and second assembly vertical arms are rotatably mounted on the inner side of the bottom of the L-shaped movable arm. The connection method of the second assembly arm assembly on the second movable arm assembly is the same as the connection method of the first assembly arm assembly on the first movable arm assembly. The height of the second assembly arm assembly on the second movable arm assembly is higher than the height of the first assembly arm assembly on the first movable arm assembly.
[0020] In a preferred embodiment of an integrated busbar for battery pack assembly, the locking shaft is rotatably mounted on the second assembly vertical arm. At this time, the locking shaft slides within the movable arc groove, and the locking collar is located outside the L-shaped movable arm.

[0022] Secondly, the present invention provides a battery pack module, employing the integrated busbar for battery pack assembly, comprising the following steps:
[0023] S1. The first moving arm assembly and the second moving arm assembly are pulled out from the busbar chassis assembly, and the first group arm assembly is tilted and swung out from the first moving arm assembly to leave battery installation compartments for multiple battery assemblies on the first group arm assembly. The second group arm assembly is tilted and swung out from the second moving arm assembly to leave battery installation compartments for multiple battery assemblies on the second group arm assembly.
[0024] S2. After the battery assembly is installed in place, the first grouping arm assembly is vertically placed on the first moving arm assembly to form the first vertical grouping module of the battery, and the second grouping arm assembly is vertically placed on the second moving arm assembly to form the second vertical grouping module of the battery.
[0025] S3. Push the first moving arm assembly and the second moving arm assembly into the busbar chassis assembly. During the process of the first moving arm assembly and the second moving arm assembly moving towards the busbar chassis assembly simultaneously, the first vertical battery assembly module and the second vertical battery assembly module form a staggered battery assembly module structure on the busbar chassis assembly.
[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] 1. This invention utilizes the tilting and swinging of the second and first group vertical arms on the L-shaped moving arm to create a staggered, stacked battery compartment structure between the first and second group vertical arms. At this point, multiple battery modules can be directly placed into the multiple battery compartments. After placement, the first and second group vertical arms are swung to a vertical position, causing the multiple battery compartments to move the multiple battery modules into a longitudinally grouped assembly structure. This method greatly simplifies the problems of group assembly and group binding between multiple battery modules and battery compartments.
[0028] 2. In this invention, after the battery assembly is installed in place on the first grouping arm assembly, the first grouping arm assembly is vertically placed on the first moving arm assembly to form a first vertical battery grouping module. After the battery assembly is installed in place on the first grouping arm assembly, the second grouping arm assembly is vertically placed on the second moving arm assembly to form a second vertical battery grouping module.

[0029] 3. The merging chassis assembly of the present invention is provided with a one-way locking gear module. When the first moving arm assembly and the second moving arm assembly are moved into place on the merging chassis assembly, the gear wheel rotates only in one direction through the cooperation between the pawl and the ratchet. At this time, the first moving arm assembly and the second moving arm assembly only perform the inward assembly assembly action on the merging chassis assembly, and do not perform the reverse outward movement action. The U-shaped chassis of the present invention is provided with a blocking block, which blocks the connecting arm to avoid excessive movement of the first moving arm assembly and the second moving arm assembly on the merging chassis assembly.

[0073] Example 2
[0074] A battery pack module, implemented using the integrated battery pack busbar, includes the following steps:
[0075] S1. The first moving arm assembly 200 and the second moving arm assembly 700 are pulled out from the busbar chassis assembly 100, and the first group arm assembly 300 is tilted and swings out from the first moving arm assembly 200, leaving battery mounting compartments for multiple battery assemblies 400 on the first group arm assembly 300. The second group arm assembly 800 is tilted and swings out from the second moving arm assembly 700, leaving battery mounting compartments for multiple battery assemblies 400 on the second group arm assembly 800.
[0076] S2. After the battery assembly 400 is installed in place, the first grouping arm assembly 300 is vertically placed on the first moving arm assembly 200 to form the first longitudinal grouping module of the battery, and the second grouping arm assembly 800 is vertically placed on the second moving arm assembly 700 to form the second longitudinal grouping module of the battery.
[0077] S3. Push the first moving arm assembly 200 and the second moving arm assembly 700 into the busbar chassis assembly 100. During the process of the first moving arm assembly 200 and the second moving arm assembly 700 moving towards the busbar chassis assembly 100 simultaneously, the first vertical battery assembly module and the second vertical battery assembly module form a staggered battery assembly module structure on the busbar chassis assembly 100.
[0078] The working principle of this invention is as follows: In existing battery assembly systems, the soft-pack battery 401 and battery compartment 303 need to be placed sequentially during assembly. After placement, a binding device is used to bind the soft-pack battery 401 and battery compartment 303 together to achieve battery assembly. However, this assembly method is too cumbersome. To overcome the above problems, this invention designs a first assembly arm assembly 300. Specifically, the first assembly arm assembly 300 includes a first assembly vertical arm 301 and a second assembly vertical arm 302. Multiple battery compartments 303 are rotatably mounted on the inner side of the grouped vertical arms 302. The bottom arms of the first grouped vertical arms 301 and the second grouped vertical arms 302 are rotatably mounted on the inner side of the bottom arm of the L-shaped movable arm 201. In actual use, the tilting and swinging of the second grouped vertical arms 302 and the first grouped vertical arms 301 on the L-shaped movable arm 201 causes the multiple battery compartments 303 to form a staggered and stacked battery compartment structure between the first grouped vertical arms 301 and the second grouped vertical arms 302. That is, at this time, the multiple battery compartments 303 form a staggered structure. The stacked battery compartment 303 structure allows multiple battery modules 400 to be directly placed within the compartments. After placement, the first and second grouping vertical arms 301 and 302 are swung to a vertical position. This causes the battery modules 400 to be assembled vertically in a longitudinal group configuration within the battery compartments 303. This significantly simplifies the grouping and binding of the battery modules 400 with the battery compartments 303. Furthermore, the structure of the second grouping arm assembly 800 is consistent with that of the first grouping arm assembly. The structure of component 300 is the same. The connection method of the second group arm assembly 800 on the second moving arm assembly 700 is the same as the connection method of the first group arm assembly 300 on the first moving arm assembly 200. The height of the second group arm assembly 800 on the second moving arm assembly 700 is higher than the height of the first group arm assembly 300 on the first moving arm assembly 200. The group placement method of the battery assembly 400 on the second group arm assembly 800 is the same as the group placement method of the battery assembly 400 on the first group arm assembly 300.
[0079] Based on the above, after the battery assembly 400 is installed on the first assembly arm assembly 300, the first assembly arm assembly 300 is vertically positioned on the first moving arm assembly 200 to form a first longitudinal battery assembly module. After the battery assembly 400 is installed on the first assembly arm assembly 300, the second assembly arm assembly 800 is vertically positioned on the second moving arm assembly 700 to form a second longitudinal battery assembly module. Since there are idle gaps between the multiple battery compartments 303 on the first assembly arm assembly 300 when the first assembly arm assembly 300 and the second assembly arm assembly 800 are vertically positioned, in order to make reasonable use of... Using this gap to optimize the space utilization during battery assembly, the present invention moves the first moving arm assembly 200 and the second moving arm assembly 700 onto the busbar chassis assembly 100, that is, the guide slider 208 slides within the side sliding groove 102, at which time the roller 209 rolls on the top surface of the U-shaped chassis 101. The connection method of the second moving arm assembly 700 on the busbar chassis assembly 100 is the same as the connection method of the first moving arm assembly 200 on the busbar chassis assembly 100. The two toothed arms 211 on the first moving arm assembly 200 and the second moving arm assembly 700 are respectively meshed with the two toothed wheels 109. On the side, after the first vertical battery assembly module and the second vertical battery assembly module are assembled, the first moving arm assembly 200 is pushed to slide into the busbar chassis assembly 100. Since the two toothed arms 211 on the first moving arm assembly 200 and the second moving arm assembly 700 are respectively meshed on both sides of the toothed wheel 109, when the first moving arm assembly 200 slides inward on the busbar chassis assembly 100, the second moving arm assembly 700 also slides inward synchronously. At this time, the first assembly arm assembly 300 on the first moving arm assembly 200 and the second assembly arm assembly 700... The assembly arm 800 moves synchronously and centered to the middle position of the busbar chassis assembly 100. After it moves into place, the multiple battery modules 400 on the second assembly arm 800 are staggered and interspersed among the multiple battery modules 400 on the first assembly arm 300. At this time, the first assembly arm 300 and the second assembly arm 800 form a complete battery assembly module on the busbar chassis assembly 100. Through the staggered interspersing and superposition of the first assembly arm 300 and the second assembly arm 800 on the busbar chassis assembly 100, the efficiency and space utilization of the multiple battery modules 400 are optimized.
[0080] Based on the above, after the first moving arm assembly 200 and the second moving arm assembly 700 have moved into position on the busbar chassis assembly 100, in order to immediately lock the moving positions of the first moving arm assembly 200 and the second moving arm assembly 700 on the busbar chassis assembly 100, the busbar chassis assembly 100 of the present invention is provided with a one-way locking gear module. Specifically, a ratchet 110 is coaxially provided on the top of the gear wheel 109, and a pawl 111 is provided on the outside of the ratchet 110. By the pushing of the push spring 107, a one-way meshing limiting structure is formed between the pawl 111 and the ratchet 110. When the first moving arm assembly 200 and the second moving arm assembly 700 are in position on the busbar chassis assembly 100, a one-way locking gear module is provided. After the first moving arm assembly 200 and the second moving arm assembly 700 are moved into place on the busbar chassis assembly 100, the gear wheel 109 rotates only in one direction through the cooperation between the pawl 111 and the ratchet 110. At this time, the first moving arm assembly 200 and the second moving arm assembly 700 only perform the inward assembly movement on the busbar chassis assembly 100, and do not perform the reverse outward movement movement. The U-shaped chassis 101 of the present invention is provided with a blocking block 104, which blocks the connecting arm 210 to prevent excessive movement of the first moving arm assembly 200 and the second moving arm assembly 700 on the busbar chassis assembly 100.
[0081] It should be noted that when the force of the push spring 107 is overcome and the pressing plate 106 is pressed, the pawl 111 and the ratchet 110 are in a disengaged state, at which time the first moving arm assembly 200 and the second moving arm assembly 700 can move in opposite directions on the confluence chassis assembly 100.
[0082] Based on the above, in order to solve the locking problem of the first group arm assembly 300 when swinging on the first moving arm assembly 200, the present invention provides a locking arm assembly 500 on the outer side of the first moving arm assembly 200. Specifically, the locking shaft 501 is rotatably mounted on the arm body of the second group vertical arm 302. At this time, the locking shaft 501 slides in the movable arc groove 206. When the first group arm assembly 300 is vertically oscillating on the first moving arm assembly 200, the pin 504 on the locking collar 502 is inserted into the first pin hole 205, realizing the vertical locking of the position of the first group arm assembly 300. When the first group arm assembly 300 is tilted on the first moving arm assembly 200, the locking arm assembly 500 is locked in place. The pin 504 on the stop ring 502 is inserted into the second pin hole 207 to achieve tilt locking of the first group arm assembly 300. At the same time, in order to facilitate the electrical connection between multiple battery assemblies 400, a busbar arm assembly 600 is provided on the top of the outer side of the first moving arm assembly 200. When the soft-pack battery 401 is placed in the battery compartment 303, the push of the top pressure spring 203 against the abutting disc 603 causes the electrical connector 602 to be inserted into the battery connector 402. The electrical connector 602 is connected to the external circuit through the electrical connection flexible wire 605. In this way, the conductive connection between multiple battery assemblies 400 on the first group arm assembly 300 when they are grouped together is achieved.
[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
