Combined mirror bracket of passenger car outside rear-view mirror

Abstract

The invention belongs to the technical field of passenger car rearview mirrors, and particularly relates to a combined mirror bracket of a passenger car outside rearview mirror, which comprises a mirror rod, a main rod and an auxiliary rod, the upper end part of the mirror rod smoothly extends towards the main rod side to be connected with the main rod, and a connecting rod connected with the auxiliary rod is arranged at the upper end of the mirror rod correspondingly; the upper end of the mirror rod and the end of the connecting rod are provided with transverse connecting pieces connected with the main rod and the auxiliary rod respectively, the rear end of the main rod and the rear end of the auxiliary rod are provided with installation bases connected with an automobile body, and a plurality of vertical connecting pieces are arranged between the main rod and the auxiliary rod in the vertical direction. The vertical connecting piece comprises an upper connecting rod connected with the main rod, a lower connecting rod connected with the auxiliary rod, a shock absorption bag sleeve located between the upper connecting rod and the lower connecting rod and a spring, cavities matchedwith the upper connecting rod and the lower connecting rod are formed in the upper end and the lower end of the shock absorption bag sleeve, the shock absorption bag sleeve is filled with shock absorption oil, and the shock absorption bag sleeve is sleeved with the spring. Transverse and longitudinal vibration transmission of the mirror frame is effectively blocked, resonance is avoided, and the stability of the outside rear-view mirror is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of passenger car rearview mirrors, in particular to a combined mirror frame for passenger car exterior rearview mirrors. Background technique [0002] The passenger car rearview mirror will vibrate during driving, which will greatly affect the driver's vision and affect safe driving. The vibration of the passenger car rearview mirror is mainly because the vibration of the car body is transmitted to the rearview mirror along the rearview mirror bracket, causing the rearview mirror to vibrate, and the rearview mirror bracket is easy to resonate with the car body, which aggravates the vibration of the rearview mirror. Vibration affects driving safety. Therefore, the vibration problem of passenger car rearview mirror needs to be solved urgently.

[0002] The passenger car rearview mirror will vibrate during driving, which will greatly affect the driver's vision and affect safe driving

The vibration of the passenger car rearview mirror is mainly because the vibration of the car body is transmitted to the rearview mirror along the rearview mirror bracket, causing the rearview mirror to vibrate, and the rearview mirror bracket is easy to resonate with the car body, which aggravates the vibration of the rearview mirror. Vibration affects driving safety. Therefore, the vibration problem of passenger car rearview mirrors needs to be solved urgently

[0003] At present, the main way to solve the above problems is to hinder the transmission of the vibration of the car body to the rearview mirror. The existing solution is to change the connection structure between the rearview mirror bracket and the car body, and set a shock absorber at the connection to hinder the transmission of vibration. However, in use, the shock absorption effect is still not obvious

Most of the existing passenger car rearview mirror brackets adopt integral welding structure, and are fixed on the passenger car body through the plug-in installation method. Once the mirror bracket is welded and processed, its natural vibration frequency is fixed, which is difficult or impossible to change. After the bus body is manufactured, the natural vibration frequency of the car body is fixed. The natural vibration frequency of different production and different models of the car body is within a certain range. Changes, the fixed vibration frequency of the existing rearview mirror bracket is easy to resonate with the car body, resulting in unavoidable vibration
