Detailed Implementation

[0029] The method of this utility model will be further described below with reference to the embodiments and accompanying drawings. This embodiment is implemented based on the technical solution of this utility model, and provides detailed implementation methods and specific operation processes, but the protection scope of this utility model is not limited to the following embodiments.

[0030] Reference Figures 1-3 This application provides a power battery fuse bracket 100, which includes a bracket body made of insulating material.

[0031] The bracket body is composed of a first plate 11, a second plate 12, and a third plate 13 connected sequentially. The first plate 11 and the third plate 13 are arranged parallel to each other in the horizontal direction, and the second plate 12 serves as a transition connection and is fixed perpendicularly to both. This structural design gives the entire fuse bracket 100 good spatial stability and can adapt to the complex spatial layout of the power battery system.

[0032] A fuse mounting structure 2 is installed longitudinally on the first plate 11, which enables the installation of the fuse 200 in the longitudinal direction.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the fuse mounting structure 2 consists of a symmetrically arranged first insert 21 and second insert 22. Both the first insert 21 and the second insert 22 are composite structures with embedded copper threaded holes in plastic parts. The first insert 21 and the second insert 22 are fixed to the first plate 11 by adhesive bonding. The threaded holes inside both inserts are connected to the first plate 11 by corrosion-resistant bolts. Figure 3 The support arm of the fuse 200 is connected to ensure installation positioning accuracy and prevent displacement. Through this design, the fuse 200 can be firmly installed on the fuse bracket 100, avoiding loosening or displacement due to external forces such as vibration during vehicle operation, thereby ensuring the normal working performance of the fuse.

[0034] Reference Figure 1 and Figure 3The second plate 12 has a transverse mounting hole 121 for laterally fixing the fuse bracket 100 to the crossbeam 400 using nails. The third plate 13 has a first longitudinal mounting hole 131 and a second longitudinal mounting hole 132 of the same specifications as the transverse mounting hole 121. These two holes form a longitudinal mounting hole, where corrosion-resistant insulating bolts are used to longitudinally fix the fuse bracket 100 to the crossbeam 400, ensuring the fuse bracket 100 is stably mounted on the crossbeam 400. This combination of transverse and longitudinal fixing ensures the stability of the fuse bracket 100 in multiple directions, allowing it to withstand various complex forces during vehicle operation without loosening or shifting, thus providing a stable mounting foundation for the fuse.

[0035] Reference Figures 1-3 To enhance structural strength, the second plate 12 in this embodiment of the application also integrates a reinforcing structure 3, which specifically includes:

[0036] Two cross-shaped reinforcing structures 31 are located on the second plate 12;

[0037] A longitudinal reinforcing structure 32 is arranged longitudinally on the second plate 12;

[0038] A first reinforcing rib 33, a second reinforcing rib 34, a third reinforcing rib 35, and a fourth reinforcing rib 36 are provided between the first plate 11 and the second plate 12. These reinforcing ribs can effectively connect the first plate 11 and the second plate 12, improving the rigidity and integrity of the entire support.

[0039] Reference Figure 2 The first reinforcing rib 33, the second reinforcing rib 34, the third reinforcing rib 35, and the fourth reinforcing rib 36 are located on the side of the first plate 11 facing away from the third plate 13. This layout allows the reinforcing ribs to function more effectively without affecting the installation space of the fuse. Through the design of these reinforcing structures, the structural strength of the entire fuse bracket is significantly improved, enabling it to better adapt to the complex working environment and mechanical requirements of the power battery system.

[0040] In addition, such as Figure 1 A fourth plate 14 is added to the side of the support body to provide lateral support for the first plate 11, the second plate 12 and the third plate 13, thereby further improving the overall rigidity and resistance to deformation.

[0041] The power battery fuse bracket of this utility model, through reasonable design and reinforcement measures, achieves the goals of high structural strength, high installation positioning accuracy and high stability, which can effectively ensure the reliable operation of the fuse in the power battery system and has good application prospects.

[0042] Reference Figure 3 This application also provides a vehicle, including a power battery fuse bracket 100, a crossbeam 400, a fuse 200, and a copper busbar 300. The specific structure of the power battery fuse bracket 100 has been described in detail above; through reasonable design, it possesses high structural strength, high installation positioning accuracy, and high stability.

[0043] The crossbeam 400 is a crucial support structure in the vehicle's power battery system, connected via mounting holes on the second plate 12 and the third plate 13. Specifically, the lateral mounting holes 121 on the second plate 12 are connected to the corresponding mounting holes on the crossbeam 400 by screws, achieving lateral fixation of the fuse bracket 100 on the crossbeam 400. The first longitudinal mounting holes 131 and the second longitudinal mounting holes 132 on the third plate 13 form longitudinal mounting holes, which are connected to the corresponding mounting holes on the crossbeam 400 by corrosion-resistant insulating bolts, achieving longitudinal fixation of the fuse bracket 100 on the crossbeam 400. This combination of lateral and longitudinal fixation ensures the stability of the fuse bracket 100 during vehicle operation and effectively withstands the mechanical forces under various complex working conditions.

[0044] The fuse 200 is a key safety protection component in the power battery system, and its support arm is mounted on the first plate 11 through a fuse mounting structure. Specifically, the support arm of the fuse 200 is connected to the threaded holes inside the first insert 21 and the second insert 22 in the fuse mounting structure through corrosion-resistant bolts, achieving high-precision installation and positioning, and ensuring that the fuse 200 will not loosen or shift during operation.

[0045] The copper busbar 300 is a conductive component that connects the fuse 200 to the battery system. It is mounted on the fuse mounting structure and connected to the arm of the fuse 200. Through this design, the copper busbar 300 can fit tightly with the fuse 200 to ensure stable current transmission, while avoiding safety hazards caused by poor contact or loose connection.

[0046] By optimizing the design of the fuse bracket 100, a stable connection with the vehicle's crossbeam 400 is achieved, while ensuring the reliable installation of the fuse 200 and the copper busbar 300. This system design not only improves the safety of the vehicle's power battery system but also enhances the overall reliability and stability of the vehicle, demonstrating promising application prospects.
