[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present utility model.
[0022] With reference to Figure 1 , Figure 3 The present utility model provides an embodiment: a double-layer alloy front anti-collision beam structure, comprising a reinforcing plate 1, a plurality of springs 2 are arranged on one side of the reinforcing plate 1, the reinforcing plate 1 is arc-shaped, a buffer pad 3 is arranged at one end of the spring 2, the buffer pad 3 is plate-shaped arc-shaped, an anti-collision beam body 4 is fixedly arranged on one side of the buffer pad 3, a buffer cavity 15 is arranged in the anti-collision beam body 4, a cross inner plate 14 is fixedly arranged in the buffer cavity 15 of the anti-collision beam body 4, the anti-collision beam body 4 is arc-trapezoidal, the length of the anti-collision beam body 4 is between 100cm-150cm, the width of the anti-collision beam body 4 is between 40mm-100mm, the height of the anti-collision beam body 4 is between 80mm-200mm, and the thickness of the anti-collision beam body 4 is between 1mm-5mm.
[0023] Specifically, when the vehicle encounters a collision, the arc-shaped reinforcing plate 1 first contacts the collision object. Due to the arc-shaped design, the collision force can be preliminarily dispersed along the arc surface in the instant of contact, avoiding stress concentration at a point and effectively buffering the initial impact force of the collision. Then, the plurality of springs 2 connected with the reinforcing plate 1 respond quickly, absorb and convert part of the collision energy by virtue of the elastic deformation characteristics, and further slow down the transmission of the impact force. The plate-shaped arc-shaped buffer pad 3 at one end of the spring 2 disperses the collision energy again by virtue of the elasticity and buffering performance, thereby reducing the subsequent impact on the anti-collision beam body 4. The anti-collision beam body 4 as the main bearing component cooperates with the buffer cavity 15 and the fixed cross inner plate 14 in the anti-collision beam body 4. The air in the buffer cavity 15 is compressed under the collision and extrusion, thereby achieving the buffering effect, and the cross inner plate 14 enhances the internal structural strength of the anti-collision beam body 4, so that the energy can be uniformly dispersed to the entire anti-collision beam body 4, avoiding stress concentration. Meanwhile, the arc-trapezoidal anti-collision beam body 4 guides the collision energy to the two sides and the rear by virtue of the shape advantage.
[0024] The arc-shaped reinforcing plate 1 and the anti-collision beam body 4 with the cross inner plate 14 support each other, so that the entire anti-collision beam structure is still stable when bearing high-strength collision, thereby greatly reducing the risk of serious deformation such as fracture and distortion. The arc-shaped reinforcing plate and the anti-collision beam body 4 with the cross inner plate 14 in the double-layer alloy front anti-collision beam structure cooperate with each other, can provide stronger supporting force and anti-deformation ability in the collision, maintain the integrity of the anti-collision beam structure, and solve the problem of excessive deformation under the collision.
[0025] Reference Figures 1-2 The cross sections of the anti-collision beam 4 and the cross inner plate 14 are in the shape of a grid. An outer energy-absorbing box 5 is symmetrically fixed on one side of the anti-collision beam 4. An outer collapse cavity 12 is provided inside the outer energy-absorbing box 5. Several fixing strips 11 are fixedly provided on the inner wall of the outer energy-absorbing box 5. An inner energy-absorbing box 10 is fixedly provided on one side of the fixing strips 11. An inner collapse cavity 13 is provided inside the inner energy-absorbing box 10. The outer energy-absorbing box 5 and the inner energy-absorbing box 10 are honeycomb in shape. A fixing plate 6 is fixedly provided at one end of the outer energy-absorbing box 5. Several nuts 7 are threadedly connected to one side of the fixing plate 6. A support structure is fixedly provided on the side wall of the anti-collision beam 4.
[0026] Specifically, when a vehicle collision occurs, the arc-shaped reinforcing plate 1 contacts the impact object, initially dispersing the impact force and reducing the concentration of the initial impact force. Immediately afterwards, the connected spring 2 uses its elastic deformation to quickly buffer some of the energy, followed by the plate-shaped arc-shaped buffer pad 3 further dispersing the energy and reducing the direct impact on the anti-collision beam 4. The cross-shaped inner plate 14 inside the anti-collision beam 4 enhances structural strength, evenly dispersing the impact energy and preventing stress concentration. Simultaneously, the honeycomb-shaped outer energy-absorbing box 5, symmetrically located on one side of the anti-collision beam 4, is subjected to force, and its internal outer collapse cavity 12 begins to collapse and deform, absorbing a large amount of energy through structural destruction. The fixing strips 11 on the inner wall of the outer energy-absorbing box 5 are firmly connected to the similarly honeycomb-shaped inner energy-absorbing box 10. The inner collapse cavity 13 inside the inner energy-absorbing box 10 also deforms and absorbs energy. The inner energy-absorbing box 10 and the outer energy-absorbing box 5 work together to absorb impact energy layer by layer. The fixing plate 6 at one end of the external energy-absorbing box 5 and the nut 7 threadedly connected to it ensure that the entire anti-collision beam structure is stably installed on the vehicle body, so that it will not shift during the collision and ensure that the energy absorption and anti-collision functions are functioning normally.
[0027] Through the front-end buffering of reinforcing plate 1, spring 2, and buffer pad 3, followed by energy dispersion of the anti-collision beam 4 and cross inner plate 14, and then deep energy absorption of the outer energy-absorbing box 5, inner energy-absorbing box 10, and their crumple zones, multi-layered buffering achieves highly efficient energy absorption. This effectively absorbs the vast majority of the energy generated by a collision, greatly reducing the impact force transmitted to the vehicle's longitudinal beams and other critical parts, minimizing vehicle damage, and ensuring the safety of passengers. The combination of multiple buffering and energy-absorbing components significantly improves the energy absorption efficiency of spring 2, buffer pad 3, inner energy-absorbing box 10, outer energy-absorbing box 5, and crumple zones, effectively coping with collisions of various intensities and reducing impact injuries to occupants.
[0028] Reference Figure 1 The support structure includes a support frame 8, with both ends of the support frame 8 fixedly installed on the side wall of the anti-collision beam 4. The support frame 8 is V-shaped, and a fixing column 9 is symmetrically fixed on one side of the support frame 8. One end of the fixing column 9 is fixedly installed on the side wall of the anti-collision beam 4.
[0029] Specifically, the support structure can be fixed to the anti-collision beam body 4. The support frame 8 is fixed at both ends of the side wall of the anti-collision beam body 4, and the other end is connected to the side wall of the anti-collision beam body 4 through the symmetrically arranged fixing column 9. At the moment of collision, the V-shaped support frame 8 utilizes its own structural characteristics, like a stable triangular support frame structure, which not only disperses part of the impact force received by the reinforcing plate 1 along its inclined two arms to the fixing column 9, and the fixing column 9 uniformly disperses the force to the side wall of the anti-collision beam body 4, avoiding damage to the reinforcing plate 1 due to excessive force on a single point, but also supports the anti-collision beam body 4 to avoid excessive deformation of the anti-collision beam body 4 during collision, while strengthening the integrity of the entire anti-collision beam structure, making it more stable when bearing impact force, and the components work more smoothly in cooperation.
[0030] The support structure composed of the support frame 8 and the fixing column 9 cooperates with each other, so that the entire anti-collision beam can still maintain the complete structural form when subjected to high-strength collision, and is not prone to serious deformation such as fracture, distortion, and component separation, ensuring to provide continuous and reliable protection for the vehicle.
[0031] Working principle: When the vehicle collides, the arc-shaped reinforcing plate 1 first contacts the collision object, and its arc-shaped structure can disperse the initial impact force. Then, the spring 2 and the plate-shaped arc-shaped buffer pad 3 buffer and absorb energy in turn, reducing subsequent impact. Subsequently, the anti-collision beam body 4 bears the main impact force, and its internal buffer cavity 15 and cross inner plate 14 cooperate to disperse energy. The one-side symmetrical honeycomb-shaped outer energy-absorbing box 5 and inner energy-absorbing box 10 begin to play a role, and the outer collapse cavity 12 in the outer energy-absorbing box 5 and the inner collapse cavity 13 of the inner energy-absorbing box 10 absorb a large amount of energy through collapse deformation. At the same time, the V-shaped support frame 8 is connected to the reinforcing plate 1 at one end and to the anti-collision beam body 4 through the fixing column 9 at the other end, which not only disperses the force received by the reinforcing plate 1, but also supports the anti-collision beam body 4 to avoid excessive deformation. Finally, the fixed plate 6 at the end of the outer energy-absorbing box 5 and the nut 7 ensure that the entire structure is stably installed on the vehicle body, and together ensure that the anti-collision beam efficiently absorbs energy and stably resists impact.
