Rearview mirror balancer of passenger car

Abstract

The invention relates to a rearview mirror balance of a passenger car. The rearview mirror balance of the passenger car comprises a balancer box and a balancer cover plate. The balancer box is arranged in a rearview mirror shell and fixedly connected with the rearview mirror shell. The balancer cover plate is fixedly connected with the balancer box. A motion cavity is formed between the balancer box and the balancer cover plate. A balance block is arranged in the motion cavity. The size of the motion cavity is larger than that of the balance block. The rearview mirror balance is simple and reasonable in structure and convenient to install; when the passenger car starts or runs or accelerates and the vibration frequency of the rearview mirror of the passenger car is changed, the balance block in the balancer box moves in the balancer box due to the shake of the rearview mirror of the passenger car, the natural vibration frequency of the rearview mirror of the passenger car is changed, and the dynamic frequency adjustment function is achieved; the frequency is adjusted in real time for preventing shake, it is guaranteed that the rearview mirror will not shake, resonance is eliminated, and the view requirement is met.

Description

technical field [0001] The invention relates to a balancer, in particular to a passenger car rearview mirror balancer. Background technique [0002] Now the exterior rearview mirrors of passenger cars all adopt long-arm exterior rearview mirrors. After the long-arm rearview mirrors are installed on the bus body, during the process of starting, driving and accelerating the bus, the vibration frequency changes, causing the rearview mirrors to vibrate at a certain level. The resonance generated in the vibration frequency range and the long-arm rearview mirror swing violently, which will have a major impact on the driver's observation of the rear of the car and the sides of the car body, and will also have a major impact on driving safety. Contents of the invention [0003] The purpose of the present invention is to provide a passenger car rearview mirror balancer which can change the natural vibration frequency of the passenger car rearview mirror, adjust the frequency at all...
