Complementary car front door bumper bar

Abstract

The invention discloses a complementary type vehicle front door crashproof rod comprising a left crashproof rod, a right crashproof rod, and a connecting piece; the connecting piece is provided with a through hole allowing the left and right crashproof rods to enter; the through hole is in a square shape, and horizontally arranged on the connecting piece; the top of the connecting piece is in an arc shape; the bottom of the connecting piece is in an arc shape; the cross section of the portions, entering the through hole, of the left and right crashproof rods is an isosceles right angled triangle; the length of the right-angle side of the isosceles right angled triangle is equal to the side length of the through hole. The complementary type vehicle front door crashproof rod is provided; the connecting intensity between the left and right crashproof rods is based on the intensity of the connecting piece, and the left and right crashproof rods are combined so as to transfer the direction of the impact force, thus improving protection effect.

Description

technical field [0001] The invention relates to a complementary type automobile front door anti-collision bar. Background technique [0002] At present, with the increasing popularity of vehicles, the safety of automobiles is also more and more valued by consumers. In order to strengthen the strength and rigidity of the doors and improve the safety performance during collisions, anti-collision bars will be installed on the doors of automobiles. The anti-collision bar of the door is generally a structure with welding mounting plates at both ends of the anti-collision bar. When the vehicle is bumpy, the anti-collision bar is prone to loosening. Since the anti-collision bar cannot be adjusted, the work of strengthening the anti-collision bar is cumbersome and requires replacement. Bumper bars add another cost. [0003] In view of the above problems, the patent document with the publication number CN204713007U discloses an adjustable automobile door anti-collision bar assembly....
