Specifically, the frame body has a first frame portion 101, a second frame portion 102, a third frame portion 103 and a third frame portion 103, wherein the first frame portion 101 and the second frame portion 101 are connected to each other. 2 are arranged at intervals in the first direction and extend along the second direction, the third frame portion 103 and the fourth frame portion 104 are arranged at intervals in the second direction and extend along the first direction, and both ends of the third frame portion 103 and the fourth frame portion 104 are respectively connected to the first frame portion 101 and the second frame portion 102, and the first frame portion 101, the second frame portion 102, the third frame portion 103 and the fourth frame portion 104 jointly enclose a rectangular installation area, and the first direction and the second direction are perpendicular to each other. For example, the first direction and the second direction are respectively configured as an attachment Figure 1 The X-axis and Y-axis directions of the mid-coordinate system.

[0034] Reference Figure 1The frame device further includes a suspension mounting device, which is arranged on the frame body 10. Specifically, the frame body 10 is provided with a first mounting point group 20 on the first frame portion 101 and the second frame portion 102, that is, the first frame portion 101 and the second frame portion 102 are provided with a single group of first mounting point groups 20, and the single group of mounting points is composed of a plurality of assembly points. Correspondingly, the suspension mounting device is arranged based on the assembly point position. In some embodiments, the suspension mounting device includes a first circular tank structure arranged at the assembly point position in the first mounting point group 20, and the axis of the first circular tank structure is parallel to In the first direction, in some embodiments, the first mounting point group 20 on the first frame portion 101 includes a first assembly point 201, a second assembly point 202 and a third assembly point 203, wherein the second assembly point 202 and the third assembly point 203 are arranged at intervals in the second direction, and correspondingly, the first assembly point 201 is located between the second assembly point 202 and the third assembly point 203 in the second direction, and is arranged at intervals from the second assembly point 202 in the third direction (for example, arranged below the first assembly point 201), wherein the third direction is perpendicular to the first direction and the second direction (exemplarily, the third direction is configured as Figure 1 In the Z-axis direction), correspondingly, the first mounting point group 20 on the second frame portion 102 includes a fourth assembly point 204, a fifth assembly point 205 and a sixth assembly point 206, wherein the fifth assembly point 205 and the sixth assembly point 206 are arranged at intervals in the second direction, and the sixth assembly point 206 is arranged between the fourth assembly point 204 and the fifth assembly point 205 in the second direction. In some embodiments, the spacing between the second assembly point 202 and the third assembly point 203 on the above-mentioned first frame portion 101 is smaller than the spacing between the fourth assembly point 204 and the fifth assembly point 205 on the second frame portion 102. In the assembly process of the frame body and the power system 70, the power system 70 composed of a motor 701 and a reducer 702 is taken as an example for explanation, referring to Figure 2 The second assembly point 202 and the third assembly point 203 on the first frame portion 101 cooperate with the sixth assembly point 206 on the second frame portion 102, or the first assembly point 201 on the first frame portion 101 cooperates with the fourth assembly point 204 and the fifth assembly point 205 on the second frame portion 102, so as to realize the installation of the motor 701. Specifically, the second assembly point 202 and the third assembly point 203 (or the fourth assembly point 204 and the fifth assembly point 205) on a single frame portion (i.e., the first frame portion 101 or the second frame portion 102) constitute the fixed points at both ends of the motor 701, and the first assembly point 201 or the sixth assembly point 206 on the other frame portion (the second frame portion 102 or the first frame portion 101) opposite thereto constitute the fixed points of the reducer 702, so as to realize the installation requirements of different modes (such as different placement positions) of the power system 70.

Correspondingly, the frame device further includes a vibration reduction device 501 mounted on the fixing points 50 fixed to the frame body 10. In some examples, the vibration reduction device 501 is mounted on the fixing points 50 by bolts. At this time, the vibration generated by the power system 70 (such as the motor 701 and the reducer 702) is first attenuated once by the motor 701 suspension in the suspension mounting device, and then attenuated twice by the vibration reduction device 501, so that the vibration value received by the vehicle body end becomes very small, thereby improving the comfort of the entire vehicle.

[0037] In some embodiments, the above-mentioned frame device also includes a fixing device 60 arranged on the third frame body 103 and the fourth frame body 104. In some embodiments, the above-mentioned fixing device 60 is configured as a U-shaped groove structure and is configured as an assembly carrier for other chassis parts (such as stabilizer bars, control walls).
