Carbon fiber reinforced composite vehicle door anti-collision beam

Abstract

The invention provides a carbon fiber reinforced composite vehicle door anti-collision beam, which relates to the technical field of vehicle engineering and solves problems of the existing vehicle door anti-collision beam of limited layout form, high mold cost, large weight and so on. The carbon fiber reinforced composite vehicle door anti-collision beam comprises an anti-collision beam, a front fixed bracket and a rear fixed bracket, wherein the front fixed bracket is connected with the front end of the anti-collision beam, and the rear fixed bracket is connected with the rear end of the anti-collision beam. The cross section of the anti-collision beam is trapezoidal; the open side of the anti-collision beam is opposite to a vehicle door inner panel; the whole anti-collision beam adopts a variable-thickness and variable-angle carbon fiber reinforced composite layer; and the front fixed bracket and the rear fixed bracket are formed by extruding aluminum alloys or stamping steel sheets so that the materials of the front fixed bracket and the rear fixed bracket are as same as that of the vehicle door inner panel. As the anti-collision beam is connected with the vehicle door inner panel by using the front fixed bracket and the rear fixed bracket, the joint strength of the carbon fiber reinforced composite vehicle door anti-collision beam is prevented from being damaged due to directly drilling holes in the carbon fiber reinforced composite vehicle door anti-collision beam; meanwhile, electrochemical corrosion and thermal expansion difference generated by different materials during connecting the fixed brackets with the vehicle door inner panel by using bolts are effectively avoided. The carbon fiber reinforced composite vehicle door anti-collision beam has the advantages of simple structure, easy molding and manufacturing, low mold cost and easy popularization and use.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a car door anti-collision beam reinforced with carbon fiber. Background technique [0002] According to relevant data in the "Compilation of Statistical Data on Road Traffic Accidents of the People's Republic of China", side collision accidents account for 32% of the traffic accidents in our country, which is higher than all other traffic accident forms and is the traffic accident with the highest frequency. Among the casualties caused by traffic accidents, the number of casualties caused by side collisions accounts for 30.1% of the total number of casualties, and it is also the form of traffic accidents that causes the most casualties. [0003] In the prior art solution, in order to strengthen the anti-collision level of the side structure of the automobile body, a door anti-collision beam is installed between the inner panel of the automobile door and the outer pane...
