The third suspension assembly 300 and the second suspension assembly 200 are arranged on the same side of the range extender 10, which improves the stability and reliability of the range extender 10 installed on the vehicle frame 20. By setting three separate suspension assemblies to fix the range extender 10, the mass of each suspension assembly is small, and the modal frequency of each suspension assembly is increased, thereby reducing the possibility and amplitude of vibration of the suspension assembly, reducing the vibration of the range extender 10 installed on the three suspension assemblies, improving the stability of the range extender 10, and thus improving the NVH (Noise, noise; Vibration, vibration; Harshness, acoustic vibration roughness) performance of the vehicle. On the other hand, the three separately arranged suspension assemblies not located on the same side can better withstand the impact and vibration in different directions during the driving of the vehicle, reduce the impact and vibration on the range extender 10, thereby ensuring the working performance of the range extender 10 and extending the service life of the range extender 10. On the other hand, each suspension assembly has a small mass and volume, is easy to pick up and place, has low assembly difficulty, and is conducive to improving the assembly efficiency of the vehicle.
