[0018] Reference Figure 1-3As shown, a lightweight anti-collision assembly for the front end of a vehicle includes an anti-collision beam 1, a bumper body 2 arranged at the front end of the anti-collision beam 1, and a connecting column 3 arranged at the rear end of the anti-collision beam 1. The connecting column 3 is symmetrically arranged at the rear end surface of the anti-collision beam 1 and is fixedly connected to the front end of the vehicle 8 through the connecting column 3. The connecting column 3 leaves a buffer space between the anti-collision beam 1 and the vehicle to provide a deformation space for the anti-collision beam 1 to absorb and release external impact force. The interior of the anti-collision beam 1 is an aerial structure with a lightweight setting, which further saves vehicle fuel consumption. The interior of the anti-collision beam 1 is evenly spaced along its length direction. A plurality of support components 4 are arranged, and the support components 4 include The first support plate 401 and the second support plate 402 are symmetrically arranged inside the anti-collision beam 1. The two ends of the first support plate 401 and the second support plate 402 are respectively connected to the inner wall of the front end and the inner wall of the rear end of the anti-collision beam 1. When the front end of the anti-collision beam 1 is impacted, the force is transmitted from the first support plate 401 and the second support plate 402 to the rear end surface of the anti-collision beam 1 for support and resistance, so as to increase the structural stability of the anti-collision beam 1 and prevent deformation. A front arc support plate 403 and a rear arc support plate 404 are arranged between the first support plate 401 and the second support plate 402. The opening end of the front arc support plate 403 is connected to the rear end surface of the anti-collision beam 1. The open end of the rear arc-shaped support plate 404 is arranged in a mirror image, and the two ends of the front arc-shaped support plate 403 are connected to the two ends of the rear arc-shaped support plate 404 to form a circular ring structure, and are connected to the first support plate 401 and the second support plate 402. The outer surface of the front arc-shaped support plate 403 conflicts with the inner wall of the front end of the anti-collision beam 1, and the outer surface of the rear arc-shaped support plate 404 conflicts with the inner wall of the rear end of the anti-collision beam 1. The front arc-shaped support plate 403 and the rear arc-shaped support plate 404 are semi-circular arc structures. The arc-shaped structure can disperse the stress to various places to form resistance, and it is not easy to break due to stress concentration. The front arc-shaped support plate 403 is subjected to stress. Afterwards, the force can be transmitted to the first support plate 401, the second support plate 402, and the rear arc support plate 403 to form resistance, and the rear arc support plate 403 and the first support plate 401 and the second support plate 402 can all be supported by the inner wall of the rear end of the anti-collision beam 1, and they cooperate with each other to effectively improve their anti-deformation ability, so that their protection performance under impact is better, and a circular ring structure is formed between the front arc support plate 403 and the rear arc support plate 403 with a deformation space in the middle, so that when the arc support plate 403 and the rear arc support plate 403 are deformed, part of the impact force can be released and then transmitted to the rear end surface of the anti-collision beam 1.
[0019] A central reinforcement 405 with a circular structure is arranged at the center of the circle between the front arc-shaped support plate 403 and the rear arc-shaped support plate 404. The central reinforcement 405 is a cylindrical structure, and its two ends are respectively connected to the top and bottom ends inside the anti-collision beam 1. A plurality of connecting members 406 are arranged on the outer surface of the central reinforcement 405 to divide the circumference equally. The ends of the plurality of connecting members 406 away from the central reinforcement 405 are connected to the inner walls of the front arc-shaped support plate 403 and the rear arc-shaped support plate 404. The central reinforcement 405 and the connecting members 406 support and limit the front arc-shaped support plate 403 and the rear arc-shaped support plate 404, increase the structural stability of the front arc-shaped support plate 403 and the rear arc-shaped support plate 404 under impact, increase their structural strength, and transmit force to various places for resistance through the connecting members 406 that divide the circumference equally, prevent the front arc-shaped support plate 403 and the rear arc-shaped support plate 404 from deformation, and further increase the protective performance of the anti-collision beam 1.
[0020] The connecting column 3 is of a rectangular structure, and an oblique reinforcement 5 is arranged at the corner of the inner wall of the front end of the connecting column 3. The oblique reinforcement 5 includes a first connecting section 501, a second connecting section 502 and an inclined section 503.

A triangular stable structure is formed between the inclined section 503 and the vertical and horizontal inner walls of the connecting column 3. The triangular stable structure formed between the inclined section and the inner wall of the connecting column 3 increases the structural strength and structural stability of the front end of the connecting column 3, reduces the deformation degree of the connecting column 3 under impact, and can form effective support and protection against external impact, thereby further improving its protective performance.
[0021] A mounting member 6 is symmetrically arranged between the bumper body 2 and the anti-collision beam 1. The mounting member 6 leaves a buffer space between the bumper body 2 and the anti-collision beam 1 to provide deformation of the bumper body 2 to slowly release and absorb impact force, and then transfer the released impact force to the anti-collision beam 1.
[0022] A plurality of buffer components 7 are arranged between the two mounting parts 6. When the bumper body 2 is deformed backward to form a collapse, the buffer component 7 is used to relieve the impact force. The buffer component 7 includes a first fixed block 701, a second fixed block 702, a telescopic rod 703 and a buffer spring 704. The first fixed block 701 is arranged on the rear end face of the bumper body 2, the second fixed block 702 is arranged on the front end face of the anti-collision beam 1, and the first fixed block 701 and the second fixed block 702 correspond to each other. The telescopic rod 703 is arranged between the first fixed block 701 and the second fixed block 702. The buffer spring 704 is sleeved On the telescopic rod 703, one end of the buffer spring 704 is in conflict with the first fixed block 701, and the other end is in conflict with the second fixed block 702. When the bumper body 1 collapses, the first fixed block 701 approaches the second fixed block 702, and causes the telescopic rod 703 to contract. At the same time, the buffer spring 704 is squeezed to deform, so as to release the impact force slowly, and the released force is transferred to the anti-collision beam 1, and the release is resisted again through the support components, so as to reduce the impact force on the anti-collision beam 1 and the vehicle 8, and reduce the external force layer by layer to make its protective performance better.
