Description

Car side mirrors with steering gear

technical field

The utility model relates to a car side rearview mirror with a steering gear, in particular to a rearview mirror structure which is easy to assemble, forms uniform frictional resistance, and can adjust torsion.

Background technique

The rearview mirrors on both sides of the vehicle can provide the user with a view of the road conditions behind the two sides when driving, so as to avoid collision accidents when the vehicle changes lanes or turns. In the current structure of the rearview mirror, a diverter that can adjust the angle of the lens is usually provided, so that the lens of the rearview mirror can be adjusted to a suitable rearward angle. In the known steering gear structure, there is a structure including a fixed seat and a movable collar pivotally arranged around the fixed seat. A long groove is formed in the bottom of the fixed seat in the radial direction, and a long groove extending axially is included in the middle of the long groove. The perforation and a plug-in piece have a horizontal hole, and the plug-in piece can extend into the through-hole so that the horizontal hole is aligned with the long groove. The pivotal assembly of the movable collar and the fixed seat is that the thin shaft rods at both ends of a strip-shaped bridge are pivotally arranged in the pivot joint groove on the opposite side of the inner wall of the movable collar, and a strip-shaped shrapnel is inserted into the long strip. The slot and the horizontal hole through which the plug piece is inserted, and then the end of the plug piece is clamped to the middle part of the bridge piece, thereby forming the steering gear structure of the rearview mirror, and the fixing seat can be fixed in the mirror housing of the rearview mirror , and then combine the lens group on the surface of the movable collar to complete the assembly of the side rearview mirror.

For this diverter structure, when assembling, the movable collar must be clamped into an ellipse shape with a jig, so that an enlarged opening in the long axis is formed between the pivot joint grooves on the opposite sides of the inner wall of the movable collar, so that the two bridges can be connected together. The thin shaft rod at the end extends into the pivot joint groove, and then the jig is released to restore the positioning collar to a circular shape, and then the bridge piece can be pivoted in the movable collar. In such an assembly process, a jig must be used to enlarge the opening of each movable collar in order to complete the pivoting of the bridge member, which makes assembly difficult and time-consuming. And the curved and deformed recovery elastic force of the elongated shrapnel pierced behind the long groove pushes the plug piece to pull the bridge piece, and then presses the pivot joint groove with the thin shaft rod pivot joint parts at both ends of the bridge piece, thus resisting the force Concentrated at the pivot joint groove, resulting in uneven distribution of frictional resistance between the movable collar and the fixed seat, making it difficult for the user to adjust a suitable rearward angle by hand. Furthermore, once the strip-shaped shrapnel is installed, the thin shafts at both ends of the bridging member press against the pivoting slot to fix the pressing force, that is, the frictional resistance between the movable collar and the fixed seat cannot be adjusted.
