Aluminum alloy lateral protection fence for vehicle

Abstract

The invention relates to an aluminum alloy lateral protection fence for a vehicle. The aluminum alloy lateral protection fence comprises a front bent beam, a hollow connecting beam and a back bent beam which are formed by extrusion of aluminum alloys, wherein the front bent beam comprises a front top plate and a front bottom plate, the surfaces of the front top plate and the front bottom plate are arranged in parallel in the horizontal direction, the lateral side at the front end of the front bottom plate is integrally connected with the lateral side at the back end of a front lower cambered bent plate, and the cambered surface of the front lower cambered bent plate bulges forwards and upwards; the back bent beam comprises a back top plate and a back bottom plate, the surfaces of the back top plate and the back bottom plate are arranged in parallel in the horizontal direction, the lateral side at the back end of the back bottom plate is integrally connected with the lateral side at the front end of a back lower cambered bent plate, and the cambered surface of the back lower cambered bent plate bulges backwards and upwards; and the front end of the connecting beam is inserted in a front insertion slot formed by the front top plate and the front bottom plate, and the back end of the connecting beam is inserted in a back insertion slot formed by the back top plate and the back bottom plate. When the protection fence collides with a human or a foreign matter, the aluminum alloy lateral protection fence for a vehicle can buffer the impact force, reduce the damage to the human and decrease the energy consumption in the running process of the vehicle.

Description

technical field [0001] The invention relates to an aluminum alloy side protection rail for a vehicle. Background technique [0002] Existing aluminum alloy side guardrails for vehicles are usually made of steel and have a relatively complex structure, and their own weight is also relatively large, which will increase energy consumption during vehicle driving, and do not have impact resistance and buffer structure design. In addition, the existing aluminum alloy side guardrails for vehicles have many sharp edges and corners. When the guardrail collides with people or foreign objects, it cannot alleviate the impact force. Because it cannot reduce the damage to people or reduce the damage to objects, often cause more serious injury accidents, or cause serious damage to objects. Contents of the invention [0003] The purpose of the present invention is to provide a protection fence that can alleviate the impact force when the guardrail collides with people or foreign objects,...
