By embedding the battery assembly 2000 in the cavity 1003 of the frame assembly 1000, the space of the chassis structure can be effectively utilized, the compactness of the overall design can be improved, and the influence of external impact and vibration on the battery can be reduced, thereby prolonging the service life of the battery.

[0028] In this embodiment, the first frame assembly 1001 includes two relatively arranged first brackets 1101. The two ends of the first bracket 1101 are respectively connected to the front suspension 110 and the rear suspension 120 of the vehicle. The second frame assembly 1002 includes two relatively arranged second brackets 1201. Among them, the second bracket 1201 has an "I"-shaped cross-section. The relative arrangement of the first bracket 1101 and the second bracket 1201, as well as the "I"-shaped cross-section design of the second bracket 1201, can effectively improve the overall structural stability of the frame assembly. At the same time, connecting the first bracket 1101 to the front suspension 110 and the rear suspension 120 of the vehicle can evenly distribute the load of the vehicle, thereby improving the load-bearing capacity of the vehicle. In addition, the "I"-shaped cross-section design of the second bracket 1201 can effectively reduce the weight of the frame assembly while ensuring strength, thereby improving the fuel efficiency and handling performance of the vehicle.

[0029] In this embodiment, the battery assembly 2000 has a cuboid structure, and the size scale of the battery assembly 2000 is (0.9 - 1.2) m × (0.4 - 0.6) m × (0.8 - 0.12) m. Through reasonable size design, the battery assembly 2000 can better adapt to the internal space of the vehicle and optimize the space utilization rate. As a preference of this embodiment, the weight of the battery assembly 2000 is also less than that of a conventional vehicle battery assembly, so that the center of gravity of the vehicle can be effectively reduced, making the vehicle more stable during driving and having a faster driving speed.

[0030] In this embodiment, the first bracket 1101 has a rectangular cross-section, and the battery assembly 2000 has the same height as the first bracket 1101. Among them, the rectangular cross-section design of the first bracket 1101 and the same height of the battery assembly 2000 enable the two to better match during installation, enhancing the consistency and stability of the overall structure, and helping to better utilize the internal space of the vehicle and avoid space waste.

[0031] In this embodiment, side rods 1102 are provided on both sides of the first bracket 1101. Two connecting rods 1103 connecting the first bracket 1101 and the side rods 1102 are provided at the middle positions of the first bracket 1101 and the side rods 1102. The side rods 1102 are used to enhance the stability of the vehicle chassis structure, thereby effectively enhancing the overall stability and rigidity of the vehicle chassis structure.

By setting a larger number of connecting rods 1103, the overall stability and rigidity of the vehicle chassis structure can be further enhanced. At the same time, the mechanical properties of the frame assembly can be optimized, and the overall load-bearing capacity can be improved.

[0033] In this embodiment, fixing rods 1104 are further provided at both ends of the side rod 1102 and the first bracket 1101. The fixing rods 1104 are used to reinforce the connection between the side rod 1102 and the first bracket 1101.

One end of each support rod 1105 is fixedly connected to the first bracket 1101 through a connecting member 1106, and the other end of the support rod 1105 is fixedly connected to the front suspension 110. A cross bar 1107 is further provided between the support rods 1105. By providing the support rods 1105 at the bottoms of the two first brackets 1101, the supporting capacity of the overall structure can be effectively enhanced, the stability of the vehicle chassis can be improved, and the cross bar 1107 can improve the connection strength between the support rods 1105, enhance the anti-torsion ability of the vehicle during driving, and increase safety.

[0035] In this embodiment, three openings 1202 are provided on one of the second brackets 1201. The battery assembly 2000 includes a positive electrode column 2001, a negative electrode column 2002, and a battery external interface 2003. The positive electrode column 2001, the negative electrode column 2002, and the battery external interface 2003 are all inserted into the openings 1202 and connected to the vehicle control system. By reasonably arranging the openings 1202, the space of the second bracket 1201 can be better utilized, space waste can be avoided, the compactness of the overall design can be improved, and at the same time, the connection stability and reliability can be ensured, and the risk of poor contact can be reduced.

[0036] In this embodiment, at least one connection block 2004 is provided at both ends of the battery assembly 2000. The second bracket 1201 has a groove 1203. The groove 1203 can receive the connection block 2004, and the connection block 2004 is fixedly connected to the groove 1203 by bolts. The tight fit between the connection block 2004 and the groove 1203 and the bolt fixation can effectively enhance the connection stability between the battery assembly and the second bracket 1201, and can improve the seismic performance of the battery assembly during vehicle driving, increasing safety.
