A car interior rearview mirror

Abstract

The invention discloses a rear-view mirror in an automobile. The rear-view mirror in the automobile comprises a mirror base, a mirror shell, a lens installed on the mirror shell and a connection supporting frame. The connection supporting frame and the mirror shell are integrally formed. The connection supporting frame is located in a cavity formed by the lens and the mirror shell. An anti-loosening boss is arranged on the connection supporting frame and a mirror base connection hole and a bolt hole are formed. A groove containing a locking nut is formed in the anti-loosening boss. The end of the mirror base is inserted into the mirror base connection hole. The bolt is inserted into the bolt hoe and penetrates through the end of the mirror base and the bottom of the groove to be matched with the locking nut. The mirror shell is locked and fixed to the mirror base. The end of the anti-loosening boss is provided with a structure preventing the locking nut from falling. The structure can prevent the locking nut from loosening and falling onto the bottom of the cavity formed by the lens and the mirror shell, abnormal sound and vibration of the rear-view mirror in the running vehicle are relieved and the rear-view mirror is convenient to maintain.

Description

technical field [0001] The invention relates to an automobile component, in particular to an automobile interior rearview mirror. Background technique [0002] The interior rearview mirror of the car is installed on the upper middle part of the front windshield through the connection of its mirror base, for the driver to observe the rear side of the vehicle. Such as figure 1 As shown, it includes a mirror base 2, a mirror case 1, a lens 3 mounted on the mirror case, and a connecting bracket 6 integrally formed with the mirror case. The connecting bracket is located in the cavity formed by the lens and the mirror case, and the connecting bracket is provided with The anti-loose boss has a connecting hole and a bolt hole for the mirror base. The anti-loose boss has a groove for accommodating the lock nut 5. The end of the mirror base 2 is inserted into the connecting hole of the mirror base, and the bolt 4 is inserted into the bolt The end of the hole passing through the mirr...

AI Technical Summary

Problems solved by technology

[0003] This type of interior rearview mirror has the following problems: (1) Since the lock nut is located in the groove of the anti-loose boss, and the connecting bracket with the anti-loose boss is located in the cavity formed by the lens and the mirror housing, once the lens is installed, it will It can no longer be easily removed. When the vehicle is running for a period of time, due to the attenuation of the lock nut torque, it will gradually loosen, and the depth of the groove is less than or equal to the height of the lock nut. Eventually, the lock nut will fall to the bottom of the cavity, causing the vehicle to run The collision between the inner lock nut and the lens and the mirror housing produces abnormal noise, which cannot be eliminated; (2) Due to the falling of the lock nut, the locking of the mirror housing and the mirror holder fails, and the shaking of the inner rearview mirror affects the driver's field of vision when the vehicle is running , thereby affecting life safety; (3) Since the lock nut falls to the bottom of the cavity, it can only be repaired after separating the lens from the mirror housing, which is inconvenient to maintain

Although the inner rearview mirror is locked and fixed with a lock nut, this measure only delays the moment decay time in practical application, and does not fundamentally solve the abnormal sound of the inner rearview mirror when the vehicle is running. Vibration problems and inconvenient maintenance problems
