Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a BMS combined bracket, including a mounting frame 1. The mounting frame 1 has a support plate 2 inside. The mounting frame 1 serves as the basic frame of the entire combined bracket and provides the necessary support structure. The support plate 2 has buffer structures 3 at the four corners of its lower end face. The support plate 2 directly supports the main components of the battery management system. The support plate 2 is connected to the mounting frame 1 through the buffer structures 3 at the four corners, effectively reducing the impact of vibration and impact on the battery management system. The upper end face of the support plate 2 has two connecting rods 4 detachably connected to its front and rear ends by bolt assemblies. A pressure plate 5 is fixedly connected between two adjacent connecting rods 4 laterally. The connecting rods 4 and the pressure plate 5 are used to fix the car battery and prevent it from moving during transportation or use. The upper end face of the mounting frame 1 has connecting plates 6 fixedly connected to its ends. The connecting plates 6 are detachably connected to a top plate 7 by bolt assemblies. The top plate 7 and the space below form a semi-enclosed space, which helps to protect the battery management system from the influence of the external environment.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the buffer structure 3 further includes connecting blocks 301 fixed at the four corners of the lower end face of the support plate 2. Each connecting block 301 is provided with a first connector 302. The mounting bracket 1 is equipped with four second connectors 303 corresponding to the first connectors 302. Nuts 304 are threaded onto both the first connectors 302 and the second connectors 303. A damping rod 305 is fixedly connected between adjacent first connectors 302 and second connectors 303. A spring 306 is sleeved on the damping rod 305. The upper and lower ends of the spring 306 are fixedly connected to the first connectors 302 and the second connectors 303, respectively. This effectively achieves buffer protection for the support plate 2 and the car battery on it. When subjected to impact or vibration, the spring 306 can absorb energy, and the damping rod 305 can slow down the transmission of vibration, thereby protecting the car battery from damage and improving the stability and reliability of the car battery.

[0032] like Figure 2 As shown, in a preferred embodiment, based on the above method, the upper end face of the support plate 2 is further further provided with side plates 8 fixedly connected to both ends, and the side plates 8 are provided with waist-shaped holes 9; the design of the side plates 8 increases the strength and rigidity of the support plate 2, and can also limit the placement of the car battery, and the opening of the waist-shaped holes 9 can reduce the overall weight.

[0033] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, both the mounting frame 1 and the support plate 2 are provided with weight-reducing holes 10, and a set of strip openings 11 are provided at equal intervals on the top plate 7. The weight-reducing holes 10 reduce the weight of the mounting frame 1 and the support plate 2, reduce the material cost of the overall structure, and also facilitate heat dissipation. The strip openings 11 on the top plate 7 further enhance the heat dissipation effect, avoid performance degradation or damage caused by overheating of the equipment, and improve the operational stability and lifespan of the equipment.

[0034] like Figure 6 As shown, in a preferred embodiment, based on the above method, a set of reinforcing blocks 12 are uniformly fixedly connected inside the connecting plate 6, and a set of vertical openings 13 are uniformly opened on the vertical wall of the connecting plate 6; the reinforcing blocks 12 improve the structural strength of the connecting plate 6 and prevent deformation due to excessive load, and the vertical openings 13 can improve the ventilation effect and reduce the weight.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, mounting holes are further provided at the four corners of the bottom of the mounting bracket 1 and at both ends of the front and rear of the connecting plate 6; the mounting holes facilitate the connection of the mounting bracket 1 to the mounting component, and also facilitate the connection of the mounting bracket 1 to another connecting plate 6, making it convenient for assembly.

[0036] Specifically, when this BMS combination bracket is in operation / use: first, the car battery is placed on the support plate 2, then the pressure plate 5 is clamped onto the car battery, and then the connecting rod 4 is connected to the support plate 2 by bolt assembly. Then, another mounting bracket 1 is installed on the connecting plate 6 by bolt assembly, and the battery installation continues. Finally, the top plate 7 is connected to the connecting plate 6 by bolt assembly. When a single battery needs to be replaced, the connecting rod 4 and pressure plate 5 at the location of the car battery to be replaced can be removed to replace the car battery. When subjected to external vibration, the spring 306 can absorb energy, and the damping rod 305 can slow down the vibration transmission, thereby protecting the car battery from damage and improving the stability and reliability of the car battery.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
