[0030] like Figures 1 to 7As shown, this embodiment provides a frame assembly, including: a main frame 1, a sub-frame 2 and a motor suspension system 3 for installing a motor 31, the sub-frame 2 is connected to the main frame 1 and is located on one side of the main frame 1 along the height direction of the main frame 1, the motor suspension system 3 includes a first suspension 32, a second suspension 33 and a third suspension 34 connected to the motor 31; the main frame 1 includes a first longitudinal beam 11, a second longitudinal beam 12 and a reinforcing cross beam 13, the first longitudinal beam 11 and the second longitudinal beam 12 are arranged opposite to each other and spaced from each other, and the reinforcing cross beam 13 is connected between the first longitudinal beam 11 and the second longitudinal beam 12.

[0031] Furthermore, one end of the first suspension 32 is connected to the motor 31, and the other end of the first suspension 32 is connected to the subframe 2, and the first suspension 32 is closer to the second longitudinal beam 12 relative to the first longitudinal beam 11; one end of the second suspension 33 is connected to the motor 31, and the other end of the second suspension 33 is connected to the first longitudinal beam 11; one end of the third suspension 34 is connected to the motor 31, and the other end of the third suspension 34 is connected to the reinforcing beam 13.

[0032] In this embodiment, one end of the second suspension 33 is connected to the first longitudinal beam 11, and one end of the third suspension 34 is connected to the reinforcing cross beam 13. The second suspension 33 and the third suspension 34 are not installed on the sub-frame 2, which can save the installation space on the sub-frame 2, thereby playing the role of avoiding components such as the steering motor 31 and the anti-roll bar.

[0033] In this embodiment, in order to fully consider the relationship between performance and lightness, the first suspension 32, the second suspension 33 and the third suspension 34 are all aluminum alloy integrated structures.

[0034] In this embodiment, combined with Figure 1 and Figure 2 As shown, the first longitudinal beam 11, the second longitudinal beam 12 and the reinforcing cross beam 13 all have lower wing surfaces a and upper wing surfaces that are arranged oppositely along the height direction of the main frame 1. One end of the second suspension 33 is connected to the motor 31, and the other end of the second suspension 33 is connected to the lower wing surface a of the first longitudinal beam 11; one end of the third suspension 34 is connected to the motor 31, and the other end of the third suspension 34 is connected to the lower wing surface a of the reinforcing cross beam 13.

Therefore, the lower wing surface a within the first installation area b is compared with the lower wing surface a of the entire first longitudinal beam 11 except the first installation area b, that is, the lower wing surface a within the first installation area b is closer to the upper wing surface corresponding to the first installation area b than the lower wing surface a of the entire first longitudinal beam 11 except the first installation area b.

[0040] It should be understood that the lower wing surface a outside the second installation area c should refer to the lower wing surface a of the entire reinforcing beam 13 except the second installation area c. Therefore, the lower wing surface a within the second installation area c is compared with the lower wing surface a of the entire reinforcing beam 13 except the second installation area c, that is, the lower wing surface a within the second installation area c is closer to the upper wing surface corresponding to the second installation area c relative to the lower wing surface a of the entire reinforcing beam 13 except the second installation area c.

[0053] In this embodiment, the third active side bracket 341 is connected to the third passive side bracket 342 through the third elastic buffer 343. The third elastic buffer 343 can reduce the vibration transmitted from the motor 31 to the reinforcing cross beam 13 to a certain extent, so as to improve the NVH performance of the whole vehicle. In addition, the third active side bracket 341 and the third passive side bracket 342 are connected by the M12 bolt 4, which is not only convenient for assembling the third suspension 34, but also convenient for later maintenance and repair of the motor 31 or the third elastic buffer 343, etc., and improves the convenience of disassembly and assembly.

Among them, the third active side bracket 341 has a "staircase" structure, which can reasonably avoid the surface structural features of the motor 31 and improve the rigidity and modal performance of the third active side bracket 341.

[0058] Combination Figure 1 and Figure 7 As shown, the third passive side bracket 342 includes a first fixing surface 342 a and a second fixing surface 342 b intersecting each other, and both the first fixing surface 342 a and the second fixing surface 342 b are used to connect with the reinforcing cross beam 13 .

[0066] In this embodiment, the motor suspension system 3 adopts a three-point center of mass arrangement, so that the center of mass of the motor 31 falls within the triangular area formed by the first suspension 32, the second suspension 33 and the third suspension 34, and is consistent with the center of gravity of the triangular area, thereby achieving better torsional resistance of the motor suspension system 3.
