Description

Technical Field

[0001] This utility model relates to the field of battery module fixing technology, specifically a detachable frame structure for a battery module. Background Technology

[0002] In modern energy storage systems, battery modules are widely used in various scenarios, such as electric vehicles, energy storage power stations, and portable electronic devices. A battery module typically consists of multiple individual cells connected together in a specific way to form a complete power supply unit. To ensure the safety and stability of the battery module, a suitable frame structure needs to be designed to support and protect these cells.

[0003] In existing battery module frame designs, it is often difficult to achieve quick and effective positioning when dealing with cylindrical batteries of different heights and specifications. That is, the existing frame structure is usually fixed and lacks flexibility, and cannot be adjusted according to the height of the battery. This leads to the need to customize special frames for each type of battery with different heights during the assembly process, which increases production costs and time consumption. Furthermore, due to the lack of universality, once the battery specifications change, a new frame needs to be redesigned and manufactured. This not only reduces production efficiency but also increases the complexity of inventory management. At the same time, the traditional frame is cumbersome to disassemble and assemble, making it inconvenient for on-site maintenance personnel to quickly complete the installation and replacement of batteries, which affects the ease of use and maintenance efficiency of the battery module. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable frame structure for battery modules, so as to solve the problems mentioned in the background art regarding the poor adaptability of current battery module frame structures to cylindrical batteries of different specifications and heights, and the inconvenience of assembly and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable frame structure for a battery module, including a frame side plate, on which several vertically distributed fixing strips are detachably installed. The upper end of the fixing strip is provided with an adjustment block through a guide groove. The adjustment block is provided with an elastic clamping member for limiting the upper part of the single battery cell. The bottom end of the fixing strip is provided with a bottom tray. The bottom tray is symmetrically provided with an elastic clamping mechanism composed of an outer clamping member and an inner clamping member. The two sides of the bottom tray are provided with a quick adjustment mechanism for fine-tuning the position of the elastic clamping mechanism.

[0006] Preferably, guide sleeves are provided in the middle of both sides of the fixing strip, and guide rods are inserted inside the guide sleeves, and the top end of the guide rods is fixedly connected to the bottom end of the adjusting block through a connecting block.

[0007] Preferably, the elastic clamping member is an arc structure made of spring steel sheet, and a protective pad is adhered and fixed on the inner wall of the elastic clamping member.

[0008] Preferably, both the outer clamping member and the inner clamping member are arc-shaped structures, and an elastic pad is provided between the outer clamping member and the inner clamping member. Furthermore, both the upper and lower ends of the outer clamping member are connected to the inner wall of the bottom tray through elastic elements.

[0009] Preferably, the quick adjustment mechanism includes an adjusting bolt, a pressure block, and a pressure-bearing interface. The adjusting bolt is threaded through both sides of the bottom tray, the pressure block is fixed at the end of the adjusting bolt located inside the bottom tray, and the pressure-bearing interface is fixed in the middle of the outer wall of the outer clamp and matches the structure of the pressure block.

[0010] Preferably, the bottom of the base tray is provided with a plurality of support members evenly distributed, and the inner end of the support member is welded and fixed to the corresponding connection point of the outer wall of the fixing strip.

[0011] Compared with existing technologies, the advantages of this utility model are: the detachable frame structure of the battery module can quickly adapt to cylindrical batteries of different heights, providing stable positioning while simplifying the assembly and disassembly process, improving operational efficiency, reducing maintenance costs, and enhancing the reliability and flexibility of the battery module. The detachable frame structure of the battery module achieves rapid adjustment of batteries of different heights through the detachable design of the fixing strip and frame side plates, and the sliding of the adjusting block within the guide groove. The spring steel sheet structure of the elastic clamping component ensures effective positioning, and the protective pad prevents damage to the battery surface. The elastic clamping mechanism in the bottom tray tightly wraps around the bottom of the battery, enhancing the fixing effect. Simultaneously, the quick adjustment mechanism allows for convenient fine-tuning of the position, accurately adapting to the battery size. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a detachable frame structure for a battery module, including a frame side plate 1. Several vertically distributed fixing strips 2 are detachably mounted on the frame side plate 1. The upper and lower ends of the fixing strips 2 are connected to the frame side plate 1 by fastening screws. An adjusting block 3 is provided at the upper end of the fixing strip 2 via a guide groove. A fixing bolt is inserted at the bottom end of the adjusting block 3 via a threaded structure. An elastic clamping member 4 for limiting the upper part of a single battery cell is provided on the adjusting block 3. A bottom tray 5 is provided at the bottom end of the fixing strip 2. An elastic clamping mechanism 6, composed of an outer clamping member 61 and an inner clamping member 62, is symmetrically arranged inside the bottom tray 5. Quick adjustment mechanisms 8 for fine-tuning the position of the elastic clamping mechanism 6 are provided on both sides of the bottom tray 5. When the frame side plate 1 is used to install individual batteries of different heights by fixing several fixing strips 2, the adjusting block 3 can slide up and down through the guide groove at the upper end of the fixing strip 2. This, combined with the elastic clamping member 4, securely limits the upper part of the battery, ensuring its stability and safety within the frame. The elastic clamping member 4 is designed to accommodate batteries of different diameters and provides appropriate clamping force to prevent loosening. Simultaneously, the bottom tray 5, through the elastic clamping mechanism 6 composed of outer clamping member 61 and inner clamping member 62, tightly wraps the battery on both sides of the bottom, further enhancing its fixation. The quick-adjustment mechanism 8 allows the operator to fine-tune the position of the elastic clamping mechanism 6 for precise battery adaptation. The dimensions ensure optimal fixation for each battery. Overall, this frame structure solves the problem of quickly and effectively positioning cylindrical batteries of different heights in existing technologies, avoiding the need for custom-made frames due to changes in battery height, reducing production costs and time. Furthermore, this design improves the versatility of the frame structure, eliminating the need to redesign and manufacture new frames even if battery specifications change, simplifying inventory management. It also optimizes the assembly and disassembly process of individual batteries, allowing on-site maintenance personnel to more easily install and replace batteries, improving the ease of use and maintenance efficiency of the battery module. Guide sleeves 11 are provided in the middle of both sides of the fixing strip 2, and the guide sleeves 11 are connected by threads... The structure is connected by locking screws, and a guide rod 10 is inserted inside the guide sleeve 11. The top end of the guide rod 10 is fixedly connected to the bottom end of the adjusting block 3 via a connecting block. Both sides of the upper guide groove of the fixing strip 2 are provided with vertical through-holes that cooperate with the connecting block at the top of the guide rod 10. With this structure, the operator can adjust the position of the adjusting block 3 by loosening or tightening the locking screws on the locking guide sleeve 11, thereby accommodating single batteries of different heights. The movement of the guide rod 10 within the guide sleeve 11 provides precise guidance for the adjusting block 3, ensuring its linearity and stability. This allows the battery to be positioned quickly and accurately during installation, simplifying the assembly process and reducing safety hazards caused by positional deviations, thus significantly improving operating efficiency and maintenance convenience.The elastic clamping member 4 is an arc-shaped structure made of spring steel sheet, and a protective pad is bonded and fixed to the inner wall of the elastic clamping member 4. This structure of the elastic clamping member 4 can provide a stable clamping force through the elasticity of the spring steel sheet itself and the arc shape, ensuring the stable positioning of the single battery cell, and can adapt to batteries of different diameters, providing a uniform pressure distribution and preventing the battery from shaking or shifting within the frame. At the same time, the protective pad bonded and fixed to its inner wall not only avoids scratches or damage that may be caused by the spring steel sheet directly contacting the battery surface, but also provides additional friction, enhancing the clamping effect. Both the outer clamping member 61 and the inner clamping member 62 are arc-shaped structures. Furthermore, an elastic pad is provided between the outer clamping member 61 and the inner clamping member 62, and both the upper and lower ends of the outer clamping member 61 are connected to the inner wall of the bottom tray 5 through the elastic member 7. This structure, with its arc-shaped outer clamping member 61 and inner clamping member 62, closely conforms to the shape of the battery, providing excellent containment and adaptability, allowing them to stably fix batteries of different diameters. The elastic pad, located between the outer clamping member 61 and the inner clamping member 62, not only reduces wear that may be caused by direct metal contact between the two but also acts as a buffer, protecting the battery from compression damage. The elastic member 7 provides appropriate clamping force, enhancing the grip on various sizes of batteries. The adaptability of the battery simplifies the installation process and improves operating efficiency. The quick adjustment mechanism 8 includes an adjusting bolt 81, a pressure block 82, and a pressure-bearing interface 83. The adjusting bolt 81 is threaded through both sides of the bottom tray 5. The pressure block 82 is fixed to one end of the adjusting bolt 81 located inside the bottom tray 5. The pressure-bearing interface 83 is fixed to the middle of the outer wall of the outer clamping member 61 and matches the structure of the pressure block 82. With this structure, the operator can precisely adjust the position of the elastic clamping mechanism 6 by rotating the adjusting bolt 81. That is, when the adjusting bolt 81 rotates, it drives the pressure block 82 to move along the thread direction, and the pressure block 82 then... Pressure is transmitted through the pressure-bearing interface 83, allowing the external clamping member 61 to adjust its position according to the actual size of the battery. This coordinated operation not only enables rapid adaptation to batteries of different specifications but also ensures that the pressure applied to the battery by the external clamping member 61 is uniform and appropriate, avoiding excessive tightness or looseness. Several support members 9 are evenly distributed at the bottom of the bottom tray 5, and the inner ends of the support members 9 are welded and fixed to the corresponding connection points of the outer wall of the fixing strip 2. This structure, with support members 9 evenly distributed at the bottom of the bottom tray 5, provides solid support for the bottom tray 5, preventing deformation or sinking when bearing the weight of the battery and external pressure.

[0018] Working Principle: When using the detachable frame structure of this battery module, firstly, the fixing strip 2 is installed onto the frame side plate 1 using fastening screws, ensuring that the fixing strip 2 is vertically distributed and firmly connected. Next, according to the height requirements of the individual battery, the locking screws on the guide sleeve 11 are loosened, allowing the adjusting block 3 to slide up and down within the guide groove at the upper end of the fixing strip 2. After adjusting to the appropriate position, the locking screws are tightened again to fix the position of the adjusting block 3. At this time, the movement of the guide rod 10 within the guide sleeve 11 provides precise guidance for the adjusting block 3. Then, the individual battery is placed into the bottom tray 5. The elastic clamp 4 automatically adapts to the battery diameter and provides appropriate clamping force through the elasticity of the spring steel sheet. At the same time, the bottom tray... The outer clamping member 61 and the inner clamping member 62 inside tightly wrap around the bottom sides of the battery. The elastic pad acts as a buffer between the outer clamping member 61 and the inner clamping member 62. The elastic member 7 applies appropriate clamping force from the top and bottom ends to ensure that the battery is stable and does not move. If it is necessary to fine-tune the position of the elastic clamping mechanism 6 to adapt to batteries of different sizes, the operator can achieve this by rotating the adjusting bolt 81 in the quick adjustment mechanism 8. The adjusting bolt 81 drives the pressure block 82 to move along the thread direction and transmits pressure through the pressure-bearing interface 83, so that the outer clamping member 61 can be precisely adjusted according to the actual size of the battery. Through the above series of steps, the installation process of the battery module is completed, thus completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
