Left and right blind spot monitoring alarm system for back-off of semitrailer

Abstract

The invention discloses a left and right blind spot monitoring alarm system for back-off of a semitrailer, and relates to the technical field of automobiles. The left and right blind spot monitoring alarm system is characterized by comprising a control device, cameras, a displayer and an alarm. The control device comprises a guide base, two movable guide rods, two connecting rods, air cylinders and fixing plates, wherein the guide base is arranged on the upper side of the front end of a carriage, the two movable guide rods are symmetrically arranged on the two sides of the guide base, the two connecting rods are hinged to the end portions of the inner sides of the movable guide rods, the air cylinders are hinged to the end portions of the inner sides of the two connecting rods, the fixing plates are fixed on the back sides of the middle portions of the guide base, and the air cylinders are fixed on the fixing plates. The cameras are arranged on the end portions of the outer sides of the movable guide rods, the displayer is electrically connected with the cameras, and the alarm is electrically connected with the cameras and the displayer. The left and right blind spot monitoring alarm system is simple and reasonable in structure, convenient to use, capable of being adjusted, high in reliability and capable of greatly improving the safety when the semitrailer backs off, and monitoring and alarming are integrated.

Description

Technical field:

[0001] The invention relates to the technical field of automobiles, in particular to a monitoring and alarm system for left and right blind spots of a semi-trailer when reversing. Background technique:

[0002] A semi-trailer is a trailer whose axle is positioned behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is fitted with a hitch that transmits horizontal or vertical forces to the tractor. The front and compartment of the semi-trailer are generally relatively large and have a large loading capacity, but the existing semi-trailer has a potential safety hazard, that is, when the semi-trailer is reversing left and right, a gap will be formed on the front and rear of the compartment that the driver cannot see. For example, when reversing to the left, the driver cannot see the area on the right side of the front of the car from the rearview mirror. Similarly, when reversing to the right, the driver cannot see the area on the left...
