A semi-trailer rearview mirror device with turning follow-up function

Abstract

The invention discloses a semi-trailer rearview mirror device with a turning follow-up function, comprising a lower base and an upper base, a hollow tube is connected and fixed between the lower base and the upper base, and a long slot hole is opened along the direction of the central axis on the fixed hollow tube , the outer wall of the fixed hollow tube is sequentially sleeved with the rotating grooved tube and the secondary mirror surface of the rearview mirror from top to bottom, the rotating grooved tube is fixedly connected to the main mirror surface of the rearview mirror, the inner wall of the rotating grooved tube is rotatably connected to a cylindrical pin, and the cylindrical pin passes through the long slotted hole Connect the rotation control structure, the bottom of the rotation control structure is connected to the steel wire rope that controls the rotation, and the wire rope stays through the fixed hollow tube to connect to the traction device; the main mirror can follow the rotation of the vehicle to reduce the visual blind spot; when the vehicle completes the turn, it will recover In normal driving state, the main mirror returns to the original state; the rearview mirror device of the present invention also has the characteristics of simple structure, high reliability, and can meet the user's needs for rotating the rearview mirror at different angles during the turning process.

Description

Technical field [0001] The present invention belongs to the technical field of rear view and rotary devices, and in particular to a semi-trailer rear view mirror device having a turning follow-up function. Background technique [0002] At the time of the vehicle turn, due to the existence of the inner wheel difference, the inner front and the inner rear wheel of the inner rear wheel (the tire refers to the tire of the rotation side), the inner front and the inner rear wheel movement trajectory is different. It is easy to form a visual blind spot, especially a long vehicle, such as a semi-trailer, and a large visual blind spot. Once the pedestrian or non-motor vehicle appears in this area, it is easy to make a traffic accident. [0003] During the turning process, the driver uses the rearview mirror to observe the surrounding driving environment. Generally, the rear view mirror of the semi-trailer is composed of mirror body and segmented lens, fixed to the outside of the cab, due ...
