Semitrailer rearview mirror device with turning follow-up function

Abstract

The invention discloses a semitrailer rearview mirror device with the turning follow-up function. The semitrailer rearview mirror device comprises a lower base and an upper base, a fixed hollow pipe is connected between the lower base and the upper base, a long slotted hole is formed in the fixed hollow pipe in the central axis direction, and the outer wall of the fixed hollow pipe is sequentiallysleeved with a rotary slotted pipe and a rearview mirror auxiliary mirror surface from top to bottom; the rotary slotted pipe is fixedly connected with a rearview mirror main view mirror surface, theinner wall of the rotary slotted pipe is rotationally connected with a cylindrical pin, the cylindrical pin penetrates through the long slotted hole to be connected with a rotating control structure,and the bottom end of the rotating control structure is connected with a steel wire rope pull wire for controlling rotation which penetrates out of the fixed hollow pipe to be connected with a traction device; the main view mirror can rotate along with the steering of the vehicle, so that the visual blind area is reduced; when the vehicle finishes turning and returns to the normal driving state,the main view mirror returns to the original state in a follow-up manner; the semitrailer rearview mirror device further has the advantages of being simple in structure, high in reliability and capable of meeting the requirement of a user for rotating the rearview mirror by different angles in the turning process.

Description

technical field [0001] The invention belongs to the technical field of rearview mirror rotating equipment, and in particular relates to a semitrailer rearview mirror device with a turning follow-up function. Background technique [0002] When the vehicle turns, due to the inner wheel difference, that is, the turning radius difference between the inner front wheel and the inner rear wheel when the vehicle is turning (the inner wheel refers to the tire on the turning side), the movement trajectories of the inner front wheel and the inner rear wheel are different. It is easy to form blind spots, especially for vehicles with relatively long bodies, such as semi-trailers, etc., which have larger blind spots. Once pedestrians or non-motor vehicles appear in this area, it is easy to cause traffic accidents. [0003] During the turning process, the driver uses the rearview mirror to observe the surrounding driving environment. Usually, the rearview mirror of a semi-trailer is compo...
