Front and rear anti-collision beam of car protective cabin

Abstract

The invention discloses a front and rear anti-collision beam of a car protective cabin. The front and rear anti-collision beam comprises two symmetrically arranged curved arms and a bow spring plate;one ends of the two curved arms are hinged to each other; mounting assemblies are arranged at the two ends of the side walls of the two curved arms correspondingly; each mounting assembly comprises afixing fork; the inner wall of each fixing fork is rotationally connected with a rotating shaft; the side wall of each rotating shaft is sleeved with a sliding block; one end of the side wall of eachcurved arm is obliquely provided with a square sliding groove; the sliding blocks are slidably connected with the inner walls of the square sliding grooves; the two ends of the sliding blocks are provided with convex blocks; the side walls of the two convex blocks are sleeved with spring members; and one ends of the two spring members are clamped and connected with the inner walls of the two sidesof the square sliding grooves correspondingly. The frontal impact resistance of the anti-collision beam is advantageously improved, through the square sliding grooves and the spring members matched with the square sliding grooves, the lateral collision avoidance capability of the anti-collision beam is improved, the fire possibility of an engine compartment is lowered, economic losses are reduced, and the functions of the anti-collision beam are increased.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision beams, in particular to a front and rear anti-collision beams for protecting a cockpit of an automobile. Background technique [0002] A car refers to a vehicle or vehicle that rotates on land with wheels; a vehicle comes from the ancient measurement method of a car. Cars at that time generally had two wheels, so a car was called one or two when it was taken, and it was written as a car later. It can be seen that the original meaning of a vehicle refers to a vehicle that has no power itself. It is called a carriage when it is drawn by horses, and it is called a rickshaw when it is pulled or pushed by people. With the development of science and technology, there are automobiles towed by steam engines, etc., and the anti-collision beams of automobiles are important protective components in automobiles. [0003] Existing automobile anti-collision beams have single function and gen...
