Description

Anti-drop structure of integral type outside rear-view mirror Technical Field The utility model belongs to the technical field of automobile accessories, and particularly relates to an anti-falling structure of an integrated outer rearview mirror. Background In the automotive field, an integrated exterior rearview mirror assembly is installed on a vehicle door as an important component, and the stability of the integrated exterior rearview mirror assembly is important for a driver to acquire an exterior view of the vehicle and ensure driving safety. However, current exterior rear-view mirrors face severe stability challenges in practical use. When the automobile runs on a bumpy road surface, the outer rearview mirror assembly can be subjected to resonance effect generated by bumpy of the whole automobile. In the prior art, the fixing screw of the steering gear is the only part for realizing the locking connection of the lens and the lens seat. The set screw is very susceptible to rollback under prolonged vibration conditions. Once the screw is retracted, the connection between the lens and the lens base is loosened, and the risk of falling off of the lens is further generated. The automobile exterior mirror can not only lead to the fact that a driver can not normally observe the conditions outside the automobile and seriously influence the driving safety, but also possibly cause damage to the exterior mirror, and the maintenance cost of the automobile is increased. At present, aiming at the problem that an outer rearview mirror lens is easy to fall off, part of solutions are to improve connection stability by increasing the tightening torque of a fixing screw, but the effect of the mode is limited in a long-term vibration environment, and the thread structure can be damaged by too high tightening torque. Still some schemes attempt to use glue and the like for auxiliary fixation, but the durability and reliability of the glue are difficult to ensure in a complex outdoor environment, and the use of the glue also brings inconvenience to subsequent maintenance and replacement.
