Description

Technical Field

[0001] This utility model relates to the field of battery accessory technology, and in particular to a battery shockproof rubber frame. Background Technology

[0002] In the operation of new energy vehicles, energy storage power stations, and various portable electronic devices, batteries, as the core energy carriers, are inevitably subjected to external vibrations and shocks. For example, road bumps during the driving of new energy vehicles and mechanical vibrations generated by the operation of energy storage power station equipment can cause loosening of internal electrode connections and electrolyte sloshing, thereby reducing battery charging and discharging efficiency and even causing safety hazards. To ensure stable battery performance and extend battery life, battery shockproof rubber frames are widely used. Leveraging the elastic cushioning properties of rubber, they have become a common component for isolating vibrations and protecting batteries.

[0003] Currently, most battery shockproof rubber frames on the market adopt a solid, one-piece structure design. These frames utilize the elasticity of the rubber material itself to provide shock protection for the battery through wrapping and clamping. They typically also have pre-drilled fixing slots or limiting holes for assembly with the battery holder to secure the battery's position. This solid structure rubber frame is widely used in the field of battery shockproofing due to its simple manufacturing process and low cost.

[0004] However, such solid rubber frames have certain defects in actual assembly. Due to differences in cell dimensions produced by different manufacturers, some cells have different diameters, resulting in inconsistent spacing between two parallel cells during assembly. This dimensional variation makes it difficult to fit the limiting holes of the cell to the battery holder, with the hole diameter deviating too much from the actual cell size. Forcing assembly not only leads to overly tight assembly but also causes excessive pressure on the battery pack's surface separator during assembly, potentially causing damage. Separator damage directly impairs the battery's insulation performance, increases the risk of short circuits, seriously threatens the overall safety of the battery pack, and significantly shortens battery life. Therefore, a battery shock-absorbing rubber frame needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a battery shockproof rubber frame to solve the problem that when assembling a solid rubber frame, the spacing between the two parallel cells is different due to the difference in the diameter of the battery cells from different manufacturers, making it difficult to match with the limit holes of the bracket. Forced assembly can easily break the diaphragm, affecting safety and lifespan.

[0007] This utility model embodiment adopts the following technical solution: a battery shockproof rubber frame. It includes a first battery bracket, a second battery bracket, and a shockproof rubber frame. The first battery bracket and the second battery bracket have similar structures. The first battery bracket has multiple sets of mounting holes arranged in a regular matrix. Multiple sets of protrusions are installed on the first battery bracket between two sets of mounting holes to ensure uniform force distribution on both sides of the battery. Battery packs are mounted within the mounting holes. A shockproof rubber frame is provided between two adjacent sets of battery packs. The shockproof rubber frame consists of connecting ribs and multiple sets of asymmetrically arranged support parts. The contact surface of the support parts near the battery packs uses an arc interference fit to limit the movement of the battery packs.

[0008] Furthermore, the contact surface of the protrusion near the battery cell adopts an arc-shaped structure design, which matches the outer contour of the battery cell.

[0009] Furthermore, the mounting hole is chamfered near the opening, and the chamfer serves as a guide during the assembly of the battery pack.

[0010] Furthermore, the first battery bracket and the second battery bracket are symmetrically arranged during assembly.

[0011] Furthermore, the assembly holes are provided through, and a stepped portion is installed on the bottom surface of the first battery bracket to support a local position of the battery cell.

[0012] Furthermore, the inner diameter of the mounting hole is adapted to the outer diameter of a common battery cell, and the inner wall of the mounting hole is mirror-polished.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] A battery shockproof rubber bracket features a first and second battery support structure with similar symmetrical features and regularly matrixed mounting holes. This design allows for precise cell installation. The holes and a stepped base provide support, ensuring stable cell fixation and preventing lateral movement. Protrusions between the two sets of mounting holes, with an arc design that conforms to the outer contour of the battery cell, limit the bracket's position during assembly, ensuring even stress distribution on both sides of the battery, preventing localized stress concentration, and guaranteeing battery structural stability.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 3 As shown, this utility model embodiment provides a battery shockproof rubber frame, including a first battery bracket 1, a second battery bracket 2, and a shockproof rubber frame 3;

[0025] The first battery bracket 1 and the second battery bracket 2 have similar structures and are designed symmetrically during assembly. Both the first battery bracket 1 and the second battery bracket 2 have multiple sets of assembly holes 12 arranged in a regular matrix. The inner diameter of the assembly holes 12 is adapted to the outer diameter of common battery cells. The inner wall is mirror polished. When the battery cell is inserted into the assembly holes 12, it can effectively avoid scratches, wear and other damage to the surface of the battery cell during the assembly process, while ensuring the smoothness and positioning accuracy of the battery cell insertion.

[0026] Meanwhile, the assembly hole 12 is provided through, and a stepped part that contacts a part of the battery cell is fixedly installed on the bottom surface of the first battery bracket 1. The stepped part is used to support the battery cell.

[0027] Multiple sets of distributed protrusions 14 are fixedly installed on the first battery bracket 1 and the second battery bracket 2 between two sets of assembly holes 12. The contact surface of the protrusions 14 near the battery cell adopts an arc-shaped structure design, which matches the outer contour of the battery cell. After assembly, it can ensure that the force on both sides of the battery cell is uniform, effectively avoid local stress concentration, thereby ensuring the stability of the battery structure and improving the overall performance and service life of the battery.

[0028] Battery pack 4 is installed in the assembly hole 12. A shock-absorbing rubber frame 3 is set between two adjacent battery packs 4. The shock-absorbing rubber frame 3 is composed of connecting stiffeners 31 and multiple sets of asymmetrically arranged support parts 32, so that the shock-absorbing rubber frame 3 has space to avoid interference deformation. The contact surface of the support part 32 near the battery pack 4 adopts an arc structure design, which can fit with the outer surface of the battery pack 4, thereby limiting the battery pack 4 and effectively buffering the impact of external vibration on the battery pack 4.

[0029] Meanwhile, the protrusion 14 is adapted to limit the shock-absorbing rubber frame 3 during the assembly process, ensuring that it is properly positioned between the battery cells.

[0030] In the example drawings of this application, the battery pack 4 adopts a two-parallel, five-series connection method. In practical applications, the number of cells in the battery pack 4 can be flexibly adjusted according to the number of mounting holes 12 to meet the assembly requirements of different battery modules and achieve a fixed function.

[0031] Specifically, the assembly hole 12 is chamfered near the opening. When assembling the battery pack 4, the chamfer 13 serves as a guide. During the insertion of the battery cell, the chamfer 13 effectively avoids hard contact between the battery cell and the edge of the hole, reducing the risk of scratching or damage to the surface coating or separator of the battery cell.

[0032] In summary: During assembly, the battery pack 4 is first inserted into the assembly hole 12 of the first battery bracket 1 according to the positive and negative terminals. The chamfer 13 at the opening of the assembly hole 12 guides the battery cell to be inserted smoothly and prevents it from colliding and scratching with the edge of the hole.

[0033] The symmetrically designed first and second battery brackets form a stable and balanced structure after assembly. The arc-shaped protrusions 14 between the two sets of mounting holes 12 are used to limit the shock-absorbing rubber frame 3 to the middle position of the battery cell. With the interference fit between the shock-absorbing rubber frame 3 and the battery cell, the force on both sides of the battery cell and the mounting holes can be evenly distributed. The arc-shaped support 32 of the shock-absorbing rubber frame 3 is in contact with the outer surface of the battery pack 4. When external vibration occurs, the support 32 absorbs energy through elastic deformation, and the connecting ribs 31 simultaneously disperse stress, buffering the vibration impact, reducing damage to the internal structure of the battery cell caused by vibration, ensuring the structural stability of the battery pack 4, and extending the battery's lifespan.

[0034] The number of batteries contained in the battery pack 4 of this utility model can be flexibly adjusted according to the number of assembly holes 12 to meet the assembly requirements of different battery modules. During the assembly process, with the help of external tooling and positioning parts, the installation of the side brackets can be completed quickly and accurately, simplifying the assembly process.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
