[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: Figure 1 - Figure 4 As shown, the utility model provides a battery box side bracket assembly for new energy vehicles, including two No. 1 brackets 8, a No. 1 frame lower baffle 17 is fixedly connected between the two No. 1 brackets 8, and a No. 2 frame lower baffle 18 is fixedly connected to both sides of the No. 1 bracket 8. One end of the No. 2 frame lower baffle 18 is fixedly connected to the No. 2 bracket 9, and the other end of the No. 2 frame lower baffle 18 is fixedly connected to the No. 3 bracket 10. A No. 2 crossbeam 16 is provided on one side of the two No. 1 brackets 8, and a No. 1 crossbeam 15 is provided on the other side of the two No. 1 brackets 8. Both ends of the No. 3 bracket 10 are connected to the No. 2 crossbeam 16 and the No. 1 crossbeam 15 Fixed connection, both ends of the No. 2 bracket 9 are fixedly connected to the No. 2 crossbeam 16 and the No. 1 crossbeam 15, one side of the No. 3 bracket 10 is fixedly connected to the No. 2 reinforcement plate 3, one side of the No. 2 bracket 9 is fixedly connected to the No. 1 reinforcement plate 2, one side of the No. 2 reinforcement plate 3 is fixedly connected to the No. 4 bracket connecting plate 7, one side of the No. 1 reinforcement plate 2 is fixedly connected to the No. 3 bracket connecting plate 6, the No. 4 bracket 11 is fixedly connected to the center of the inner side of the No. 1 reinforcement plate 2, the No. 5 bracket 12 is fixedly connected to the No. 5 bracket 12, the top of the No. 4 bracket 11 is fixedly connected to two rectangular tubes 1, and the top of the No. 5 bracket 12 is fixedly connected to two rectangular tubes 1.

[0023] The following details the specific configuration and function of this embodiment. During assembly, the two first brackets 8 must first be installed in the appropriate positions to secure the first frame lower baffle 17. This requires ensuring that the first frame lower baffle 17 is in the correct installation position and securely fastened with bolts or other fixings. The use of the first brackets 8 ensures the stability and verticality of the first frame lower baffle 17, preventing it from shifting during subsequent installation.

[0024] Next, use the third bracket 10 and the second bracket 9 to fix the second frame lower baffle 18. By aligning and fixing the second frame lower baffle 18 with the third bracket 10 and the second bracket 9, this process ensures the stable installation of the second frame lower baffle 18 and connects it to the first frame lower baffle 17, making the overall structure more stable.

[0025] After completing the installation of each lower baffle, the installation of crossbeam 15 and crossbeam 16 began. By securely connecting crossbeam 15 and crossbeam 16 to bracket 1 8, bracket 2 9, and bracket 3 10, respectively, the overall frame support structure is further strengthened. The installation of the crossbeams not only provides additional support for the lower baffles but also effectively increases the strength of the connections between the brackets, making the entire structure more rigid and torsion-resistant. Furthermore, the strategic placement of the crossbeams distributes external loads, preventing deformation or damage caused by excessive stress at a single point.

[0026] To further enhance the stability of the frame, a second reinforcement plate 3 is installed on one side of bracket 3, and a first reinforcement plate 2 is installed on one side of bracket 2 9. Bracket 4 11 is bolted to the inside of reinforcement plate 3, while bracket 5 12 is bolted to the inside of reinforcement plate 2, creating a more stable support system. The rectangular tube 1 within brackets 5 12 and 4 11 effectively supports crossbeam 15 and crossbeam 2 16, providing additional structural support, further enhancing the stability of the beams and preventing them from deforming under load.

[0027] Furthermore, the ends of the second crossbeam 16 are bolted to the second reinforcement plate 3 and the first reinforcement plate 2, respectively. This bolted connection offers significant advantages. First, it not only ensures a secure connection but also provides ample adjustment space during installation, making adjustments easier for installers. Furthermore, the bolted connection is removable, facilitating subsequent maintenance and repair. If a component needs to be replaced, simply remove the bolts, eliminating the need for extensive disassembly of the entire frame. This significantly improves maintenance efficiency and reduces costs.

[0028] Finally, throughout the entire installation process, all components were bolted together, a method that not only improves connection convenience and stability but also greatly facilitates subsequent maintenance. Bolting not only ensures the overall rigidity of the frame but also allows for rapid disassembly and assembly when necessary, thereby improving operational flexibility and maintenance efficiency, ensuring the continuous and stable operation of the production line.

[0029] Example 2: Figure 2 - Figure 4As shown, the bottom ends of both ends of the No. 1 crossbeam 15 are fixedly connected to the rectangular tube 1, and the bottom ends of both ends of the No. 2 crossbeam 16 are fixedly connected to the rectangular tube 1. One side of the No. 1 reinforcement plate 2 is fixedly connected to the No. 1 bracket connecting plate 4, and one side of the No. 2 reinforcement plate 3 is fixedly connected to the No. 2 bracket connecting plate 5. The top inner wall of the No. 1 reinforcement plate 2 and the top inner wall of the No. 2 reinforcement plate 3 are both fixedly connected to the side wall of the No. 2 crossbeam 16. The top end of the No. 2 crossbeam 16 is fixedly connected to the top inner wall of the No. 3 bracket connecting plate 6, and the top end of the No. 2 crossbeam 16 is fixedly connected to the top inner wall of the No. 4 bracket connecting plate 7. The top end of the No. 1 crossbeam 15 is fixedly connected to the top inner wall of the No. 3 bracket connecting plate 6, and the top end of the No. 1 crossbeam 15 is fixedly connected to the top inner wall of the No. 4 bracket connecting plate 7. One end of the fifth bracket 12 and one end of the fourth bracket 11 are fixedly connected with the third reinforcing plate 13, and the top side wall of the second bracket connecting plate 5 and the top side wall of the first bracket connecting plate 4 are fixedly connected with the bracket connecting ears 14.

[0030] The entire embodiment achieves the following effect: after the second reinforcing plate 3 is connected to the first reinforcing plate 2, the third reinforcing plate 13 is bolted to one side of the fifth bracket 12 and the fourth bracket 11, while also being connected to the rectangular tube 1. This effectively reinforces the rectangular tube 1 and enhances its overall strength. The other side of the rectangular tube 1 is restrained by the first and second reinforcing plates 2 and 3, respectively, ensuring its stability during support and preventing deformation or loosening.

[0031] Bolts are used to connect the No. 2 reinforcing plate 3 and the No. 4 bracket connecting plate 7, while the No. 1 reinforcing plate 2 is fixed to the No. 3 bracket connecting plate 6 by bolts, which not only further enhances the stability of the overall structure, but also the top ends of the No. 3 bracket connecting plate 6 and the No. 4 bracket connecting plate 7 are connected to the No. 1 crossbeam 15 and the No. 2 crossbeam 16, effectively fixing the two beams together, thereby increasing the strength and durability of the overall frame.

[0032] The second bracket connecting plate 5 is bolted to the other side of the second reinforcement plate 3, while the first bracket connecting plate 4 is threaded to the other side of the first reinforcement plate 2. This design allows the second and fourth bracket connecting plates 5 and 7 to fully enclose the second reinforcement plate 3, protecting it from external impact and damage. Simultaneously, the first and third bracket connecting plates 4 and 6 enclose the first reinforcement plate 2, providing the same protective effect. This wraparound design not only provides additional protection for the reinforcement plates but also makes the overall installation process more convenient and efficient, reducing the complexity of the installation steps.

[0033] In subsequent designs, bracket connecting ears 14 were added to the second bracket connecting plate 5 and the first bracket connecting plate 4. This not only further facilitated the connection but also provided greater connection convenience for supporting the battery box. This design improved installation efficiency and ensured a more stable and secure structure when supporting the battery box.

[0034] The device's usage and operating principle: During assembly, first, use two No. 1 brackets 8 to install and secure the No. 1 frame lower baffle 17. Then, use No. 3 bracket 10 and No. 2 bracket 9 to secure the No. 2 frame lower baffle 18, completing the installation of the No. 1 frame lower baffle 17 and the two No. 2 frame lower baffles 18. Next, install the No. 2 crossbeam 16 and No. 1 crossbeam 15, securing them to the No. 3 bracket 10, No. 2 bracket 9, and the two No. 1 brackets 8, respectively. This ensures full securement of all baffles and enhances the connection strength of each bracket. Subsequently, the No. 2 reinforcement plate 3 is installed on one side of the No. 3 bracket 10, and the No. 1 reinforcement plate 2 is installed on one side of the No. 2 bracket 9. The No. 4 bracket 11 is secured to the inside of the No. 2 reinforcement plate 3 with bolts, and the No. 5 bracket 12 is secured to the inside of the No. 1 reinforcement plate 2 with bolts. The rectangular tubes 1 inside the No. 5 and No. 4 brackets 11 support the No. 1 crossbeam 15 and No. 2 crossbeam 16, respectively, further enhancing the stability of the connection. In addition, the two ends of the No. 2 crossbeam 16 are connected to the No. 2 reinforcement plate 3 and the No. 1 reinforcement plate 2 respectively by bolts. This bolt connection method not only improves the convenience of assembly, but also facilitates separate disassembly and quick maintenance. After the No. 2 reinforcement plate 3 and the No. 1 reinforcement plate 2 are connected, the No. 3 reinforcement plate 13 is fixed to the rectangular tube 1 by bolts to strengthen the stability of the rectangular tube 1, while the other side of the rectangular tube 1 cooperates with the No. 1 reinforcement plate 2 and the No. 2 reinforcement plate 3 to ensure stability during support. The No. 2 reinforcement plate 3 is connected to the No. 4 bracket connecting plate 7 by bolts, and the No. 1 reinforcement plate 2 is connected to the No. 3 bracket connecting plate 6 by bolts, thereby strengthening the overall structure, and the top ends of the No. 3 and No. 4 bracket connecting plates 7 are connected to the No. 1 crossbeam 15 and the No. 2 crossbeam 16 to further consolidate the frame structure. Finally, the second bracket connecting plate 5 is bolted to the other side of the second reinforcement plate 3, and the first bracket connecting plate 4 is threaded to the other side of the first reinforcement plate 2. The second and fourth bracket connecting plates 7 wrap around the second reinforcement plate 3, while the first and third bracket connecting plates 6 wrap around the first reinforcement plate 2, providing both protection and facilitating installation and connection. Furthermore, bracket connecting ears 14 are provided on the bracket connecting plates to assist in connection, improving the convenience of connection when supporting the battery box.
