From the point of view of NVH, to achieve good vibration isolation effect, it is necessary to avoid the frequency of engine operation. When designing the suspension system of power assembly, the natural frequency of the bracket should be optimized and tested. The existing suspension bracket usually increases rubber between the suspension bracket and the power assembly and the suspension, or uses two-stage vibration isolation by increasing rubber structure. If the amount of rubber is small, durability cracking problem will occur, and if the amount of rubber is large, it will increase the low-frequency excitation of power assembly, which will affect the NVH performance of the vehicle.

[0028] Figure 1 A front view structural schematic diagram of a suspension bracket. As shown in Figure 1 , the suspension bracket comprises a first bracket 10, a second bracket 20 and two reinforcing members 40. In the present schematic embodiment, the first bracket 10, the second bracket 20 and the two reinforcing members 40 are all plate-shaped. In this way, the processing is facilitated and the structure is simple, which is conducive to reducing the cost. Each reinforcing member 40 is attached to the second bracket 20 and located at the first cavity 30, and is arranged opposite to the first bracket 10. In this way, the modal is improved, thereby improving the NVH (NVH is the abbreviation of noise, vibration and harshness) performance.
[0029] Figure 2 A structural schematic diagram of a suspension bracket. As shown in Figure 1 and Figure 2 , the second bracket 20 is bent at both ends along the length direction thereof to form a connecting portion 22 respectively, and the two connecting portions 22 are connected to the first bracket 10 respectively, so as to ensure the strength and stability of the suspension bracket. The two connecting portions 22 are arranged in parallel and perpendicular to the first bracket 10. In this way, the second bracket 20 and the first bracket 10 enclose a first cavity 30. In this way, the overall vehicle NVH performance is improved.

The support member 50 is arranged in the first cavity 30 perpendicular to the length direction of the first bracket 10, and abuts against the first bracket 10 and the second bracket 20 respectively and divides the first cavity 30 into two second cavities 301, thereby improving the strength and stability of the suspension bracket and further reducing the vibration transmission. As shown in Figure 1 , the two reinforcing members 40 are arranged in the second cavities 304 respectively, and each reinforcing member 40 is bent and attached to the second bracket 20 and the support member 50, thereby improving the modal. Specifically, by attaching the two reinforcing members 40 to the second bracket 20, the modal of the suspension bracket can be improved from the previous 460 Hz to 510 Hz.
[0031] As shown in Figure 2 , the first bracket 10 is provided with two mounting holes 13 at both ends along the length direction thereof, and the two mounting holes 13 are arranged along the width direction of the first bracket 10. The first bracket 10 is connected to the suspension assembly by means of the mounting holes 13 at both ends. In the present schematic embodiment, the first bracket 10 is further provided with a through hole 11 at the first cavity 30, thereby effectively reducing the weight of the overall suspension bracket and effectively reducing the cost.
