Described anti-collision beam is connected with baffle plate, and described front supported beam front end is fixed on baffle plate, and described baffle plate is provided with engaging lug, and described engaging lug is fixed with connection bracket, and the other end of described connection bracket is packed in the bottom surface being fixedly mounted with support.
The two ends up and down of baffle plate are respectively equipped with the clamp stretched out to front side, and upper and lower clamp is stuck on the upper and lower end face of anti-collision beam, strengthen the Joint strenght of baffle plate and anti-collision beam.
The left and right sides, rear end of described front supported beam is connected to and is fixedly mounted with ear, and be positioned at being fixedly mounted with on ear of outside and be connected with collateral beam, the other end and the anti-collision beam of described collateral beam are affixed, and its affixed point is positioned at the outside of front supported beam and the affixed point of anti-collision beam.
Described be fixedly mounted with ear by bolt be fixedly mounted with support and connect as one.
Described front supported beam, be fixedly mounted with ear, baffle plate, anti-collision beam and collateral beam and be welded to each other and be integrated.
Described front supported beam is made up of square tube.
Described collateral beam is made up of square tube.
After adopting said structure, front supported beam is processed with the strip hole be crisscross arranged, reduce the strength and stiffness of front supported beam on the one hand, make the utility model when being collided impact, making front supported beam prior to being fixedly mounted with support reaches yield point and carries out crumple plastic deformation, and the strip hole be crisscross arranged on the other hand is that the plastic deformation of front supported beam has reserved sufficient deformation space.When front car and truck head-on crash; the stressed plastic deformation of collapsible front supported beam; collision energy is dissipated in whole impact process; reduce the deceleration value that collision produces, the function strengthening buffer action, improve energy-obsorbing and damping; prevent the fracture being fixedly mounted with support, well protect again the safety of collision partners personnel.When car and truck stagger frontal impact, namely car front sails to strike anti-collision beam outer end, because anti-collision beam both sides secure collateral beam, so the stability of the utility model both sides is stronger, prevent side local buckling from damaging, avoid car to pierce cab bottom wheel front, cause the injury of navigating mate.Simultaneously connection bracket be applied in whole before protection welding general assembly time, certain lifting effect can be played, holdout device collision is upwarped simultaneously and also play a role, prevent the car caused because device collision upwarps from piercing darker.

Detailed description of the invention
As shown in Figures 1 to 9, commercial vehicle/comm..vehicle front underrun protection device comprises anti-collision beam 1, the rear side of anti-collision beam 1 is at least connected with two front supported beams stretched backward 4, front supported beam 4 is made up of square tube, front supported beam 4 is separately positioned on the left and right sides of anti-collision beam 1, staggeredly along its length on each front supported beam 4 be provided with multiple strip hole 41, the rear end of each front supported beam 4 be connected with stretch be fixedly mounted with support 2 for what be fixedly mounted with vehicle frame.
Anti-collision beam 1 is connected with baffle plate 5, the two ends up and down of baffle plate 5 are respectively equipped with the clamp 52 stretched out to front side, and upper and lower clamp 52 is stuck on the upper and lower end face of anti-collision beam 1.Front supported beam 4 front end is fixed on the aft end face of baffle plate 5, baffle plate 5 sidepiece is provided with the engaging lug 51 stretched out to rear side, engaging lug 51 offers bolt hole, connection bracket 9 two ends are respectively equipped with bolt hole, connection bracket 9 one end is packed on engaging lug 51 by bolt, on the ear seat that the other end is stretched under being packed in and being fixedly mounted with support 2 bottom surface.The left and right sides, rear end of each front supported beam 4 is connected to and is fixedly mounted with ear 3, be positioned at being fixedly mounted with on ear 3 of outside and be connected with collateral beam 6, because the angle of inclination of often kind of collateral beam 6 of vehicle may be different, so be fixedly mounted with ear 3 can do adaptive change according to the actual conditions of collateral beam and front supported beam junction, suitably can add attaching parts and make both junction stable connections, collateral beam 6 is made up of square tube, the other end and the anti-collision beam 1 of collateral beam 6 are affixed, its affixed point is positioned at the outside of front supported beam 4 and the affixed point of anti-collision beam 1, and namely collateral beam 6 is obliquely installed.Be fixedly mounted with ear 3 by bolt be fixedly mounted with support 2 and connect as one.
