[0002] The rearview mirror is an important safety component of the car and one of the key components for the driver to obtain indirect vision. Commercial vehicles, such as trucks, travel buses, etc., are usually equipped with at least one rearview mirror on the driver's side and passenger side, and a set of support structures for mounting the rearview mirror body.

[0003] At present, the existing commercial vehicle rearview mirrors mainly use an exterior rearview mirror installation structure of a support rod + support + compression spring + upper and lower ends + bolts. This structure is commonly used in existing commercial vehicles and has been installed and verified on a large number of actual vehicles.

[0004] However, due to structural limitations, when dealing with the idling and driving of the vehicle, the modal changes are large for different models, and the stability of the exterior rearview mirror's jitter performance cannot be guaranteed.

[0005] According to the previous actual vehicle verification, the modal change scheme is adopted to improve the vibration of the exterior rearview mirror. The schemes adopted include but are not limited to: increasing the weight of the mirror body and support rod, adding vibration-damping gaskets, etc. The above schemes have a certain effect on improving the vibration, but there is a problem of vehicle consistency. It is easy to be affected by the poor consistency of the vehicle engine, white body and other components, resulting in poor consistency of the vibration effect of the exterior rearview mirror. The same parts have different vibration effects on different sample vehicles. This problem has occurred repeatedly during the early verification process. Summary of the invention
