[0002] The battery balancing module is a core component of the battery management system (BMS), designed to address inconsistencies in voltage, capacity, or state of charge (SOC) among individual cells within a battery pack due to differences in manufacturing processes, usage environments, or aging. By adjusting the energy distribution among the cells, this module can improve the overall performance of the battery pack, extend its lifespan, and ensure safety.

[0003] Existing battery balancing modules mostly use bolt fixing or welding for connection, which leads to cumbersome disassembly and assembly and difficult maintenance. Especially in scenarios where it is necessary to frequently replace individual cells or perform balancing maintenance, the existing structure often requires special tools and is time-consuming. In addition, conventional snap-fit ​​structures have problems such as poor connection stability and easy loosening after long-term use, which affects the balancing performance and safety of the battery pack. The spring design in the existing technology often has defects such as stress concentration and rapid elastic decay, which cannot meet the requirements of battery modules for long-term stability. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-release battery equalization module that solves the problems of cumbersome disassembly and assembly and difficult maintenance caused by the use of bolt fixing or welding to connect battery equalization modules.

[0006] Preferably, the disassembly plate is U-shaped, the rotating shaft is located on the two vertical surfaces of the disassembly plate, and each rotating shaft is provided with multiple snap-fit ​​plates, with the snap-fit ​​plates on different rotating shafts being staggered.

[0007] Preferably, the top of the snap-fit ​​plate has a slot through which the snap-fit ​​spring passes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-5 A quick-release battery balancing module includes a battery body 1 and a placement plate 2. The battery body 1, as the core power supply component of the entire module, provides power to the device. In practical applications such as electric vehicles and energy storage systems, it is crucial for storing and releasing electrical energy. The placement slot on the placement plate 2 provides a stable placement space for the battery body 1, ensuring that the battery does not shake or shift during operation. This protects the battery body 1 from external impacts and friction, extending its lifespan. One side of the placement plate 2 has an opening for the wires connected to the battery body 1. This opening provides a dedicated channel for the wires, preventing tangled wires and facilitating neat wiring layout and maintenance. It also reduces damage to the wires caused by bending or squeezing. The battery body 1 is located within the placement slot of the placement plate 2. A U-shaped disassembly plate 3 is fixedly installed on the top of both the battery body 1 and the placement plate 2. The U-shaped mounting plate 3 provides a mounting base for the rotating shaft 4 and the snap-fit ​​plate 5, allowing the rotating shaft 4 to pass through and rotatably connect to the vertical surface of the mounting plate 3, providing support for the rotation of the snap-fit ​​plate 5. The two mounting plates 3 are symmetrically arranged, with the rotating shaft 4 passing through and rotatably connected to the outer wall of each mounting plate 3. The rotating shaft 4 serves as the rotation center of the snap-fit ​​plate 5, supporting its rotation around which the snap-fit ​​plate 5 can engage and disengage. The snap-fit ​​plate 5 is fixedly connected to the outer wall of the rotating shaft 4. One side of the snap-fit ​​plate 5 is connected to the mounting plate 3 via the rotating shaft 4, while the bottom of the other side... The first part can be engaged with the rotating shaft 4 on another disassembly plate 3, thereby tightly connecting the two disassembly plates 3 together, thus fixing the battery body 1 and the placement plate 2. The bottom of the other side of the engagement plate 5 is engaged with the rotating shaft 4 on another disassembly plate 3. The top of the disassembly plate 3 is fixedly connected with a disassembly spring 6, which is used to fix the disassembly spring 6, ensuring that the spring can accurately cooperate with the engagement plate 5, realizing the pressure application and locking function of the engagement plate 5. The other end of the disassembly spring 6 contacts the top of the engagement plate 5. Through the innovative rotating engagement structure (rotating shaft 4 + engagement plate 5), the battery body 1 can be quickly disassembled and assembled. By driving the engagement plate 5 through the rotation shaft 4, the disassembly and assembly operation can be completed without the aid of tools, effectively improving maintenance efficiency.

[0022] Please see Figure 2-4The disassembly plate 3 is U-shaped, and the rotating shaft 4 is located on the two vertical surfaces of the disassembly plate 3. Each rotating shaft 4 is equipped with multiple snap-fit ​​plates 5. The snap-fit ​​plates 5 on different rotating shafts 4 are staggered. The staggered snap-fit ​​plates 5 form a multi-point distributed locking mechanism. Combined with the staggered layout of the spring branch, the stress distribution is more uniform, improving the structural reliability and meeting the vibration resistance requirements.

[0023] Please see Figure 3-5 The top of the snap-fit ​​plate 5 has a slot through which the snap-fit ​​spring 6 passes. The bottom of the snap-fit ​​spring 6 connects to the top of the horizontal surface of the snap-fit ​​plate 3, and the snap-fit ​​spring 6 is Z-shaped. The number of branches of the snap-fit ​​spring 6 corresponds to the number of snap-fit ​​plates 5. The branches of the snap-fit ​​spring 6 on both sides are staggered. During battery operation, the snap-fit ​​spring 6 can play a certain role in buffering and shock absorption, reducing damage to the snap-fit ​​structure caused by vibration and impact, and extending the service life of the snap-fit ​​structure. The snap-fit ​​spring 6 is made of elastic metal material and always has downward pressure on the snap-fit ​​plate 5, ensuring that the snap-fit ​​plate 5 can be tightly snapped with the rotating shaft 4 on the other snap-fit ​​plate 3, preventing the snap-fit ​​plate 5 from being accidentally loosened during operation. Through the unique Z-shaped snap-fit ​​spring 6 design and the slot structure, the locking pressure of the snap-fit ​​plate 5 is guaranteed, and the elastic deformation provides buffering, effectively preventing the connection from loosening due to vibration and effectively improving the contact stability.

[0024] In use, the battery body 1 is vertically placed into the slot of the placement plate 2. At this time, the vertical surfaces of the two disassembly plates 3 on both sides form an initial positioning with the battery casing. The opening on the side of the placement plate 2 provides a passage for the battery electrode connection wires to pass through, avoiding cable bending. The elastic metal springs generate downward pressure, causing the hook-shaped structure at the end of the snap-fit ​​plate 5 to tightly engage with the base of the rotating shaft 4 of the opposite disassembly plate 3, forming a three-point mechanical constraint. Multiple staggered snap-fit ​​plates 5 decompose the vibration load of the battery body 1 into multi-directional components. The vertical wall of the U-shaped disassembly plate 3 bears the main shear force, while the spring branches on the horizontal surface provide dynamic compensation pressure to prevent micro-displacement caused by high-frequency vibration. At the same time, the rotating shafts 4 on both sides are rotated, and the rotating shafts 4 drive the snap-fit ​​plates 5 connected to them to move. The rotation of the snap-fit ​​plates 5 causes the Z-shaped disassembly springs 6 to bend. At the moment the spring pressure disappears, the hook-shaped structure disengages from the contact surface of the base of the opposite rotating shaft 4, and the battery body 1 is in a semi-free state. The battery can be lifted directly upwards to complete the disassembly. The whole process does not require the assistance of tools.

[0025] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
