[0053] Based on the above embodiments, the elastic support assembly 4 includes an elastic buffer 401 and an elastic base plate 402. The elastic buffer 401 is disposed on the elastic base plate 402, and at least four elastic buffers 401 are provided.

[0054] For details, please refer to the appendix. Figure 1 The two lower side walls of the inner frame 3 should maintain a certain distance from the inner perimeter of the outer frame 2. This space is used to install the elastic support assembly 4. The elastic support assembly 4 includes an elastic buffer 401 and an elastic base plate 402. The elastic buffer 401 mainly plays a buffering role. The elastic buffer 401 is preferably a rubber assembly. In order to enhance the vibration isolation and buffer the instantaneous impact force and prevent damage to the suspended soft pad, the rubber assembly needs to be set with at least two layers. At least four layers of rubber assemblies are set on the left and right sides of the inner frame 3. Taking double-layer rubber as an example, it is formed by vulcanizing two layers of rubber and the base plate 1 (vulcanization refers to combining sulfur elements with other substances to form a new compound).

For details, please refer to the accompanying Figure 3 Therefore, the displacement of the elastic bottom plate 402 in the direction perpendicular to the bottom plate 1 can be limited, so that the overall anti-pulling ability of the motor suspension cushion is enhanced.

[0057] In summary, the motor suspension cushion is composed of the bottom plate 1, the outer frame 2, the inner frame 3 and the elastic support assembly 4. The bottom plate 1 is provided with four fixing holes 101 for connecting the bottom plate 1 and the vehicle frame. The rest of the bottom plate 1 is cut off except the four fixing holes 101, so that the overall weight is greatly reduced. The outer frame 2 is connected perpendicularly to the bottom plate 1, and the inner frame 3 is arranged in the inner part of the outer frame 2. The outer frame 2 and the inner frame 3 are connected through the elastic support assembly 4, which includes the elastic buffer 401 and the elastic bottom plate 402. The elastic buffer 401 is preferably a rubber assembly, which plays a main buffering role, and the elastic bottom plate 402 is clamped with the recess in the inner periphery of the outer frame 2. The outer frame 2 can support and limit the inner frame 3. There is a reinforcing rib on each side of the outer frame 2, which ensures the overall structural strength of the outer frame 2. The upper surface of the inner frame 3 is provided with two threaded holes 302 for connecting with the power assembly support and transmitting force to the elastic support assembly 4. The upper surface of the inner frame 3 is also provided with a limiting groove 301, and the inner periphery of the outer frame 2 is provided with a frame protrusion 201 matched with the limiting groove 301, so as to limit the shaking amplitude of the inner frame. Since the elastic buffer of the present scheme is preferably rubber, and at least two layers of rubber are arranged between the lower part of any one side of the inner frame 3 and the outer frame 2, the vibration isolation and buffering instantaneous impact force capacity can be further enhanced. In addition, the width of the inner frame 3 is increased, which further enhances the impact resistance.
