[0022] In order to describe the utility model in detail, a vehicle anti-collision beam and a vehicle of the utility model are specifically described below:
[0023] Please combine Figure 1 and Figure 2As shown, the utility model provides an automobile anti-collision beam, including an anti-collision beam body 2, the anti-collision beam body 2 having a collision surface for collision and a mounting surface opposite to the collision surface, a first weight reduction structure is arranged on the anti-collision beam body 2 between the collision surface and the mounting surface, a first support member 21 is arranged in the first weight reduction structure, the first support member 21 has a first end and a second end opposite to each other, the first end of the first support member 21 faces the collision surface, and the second end of the first support member 21 faces the mounting surface. By arranging the first weight reduction structure on the anti-collision body, the weight of the anti-collision beam body 2 can be reduced, the raw materials for producing the anti-collision beam body 2 can be saved, and the production cost can be reduced. The first support member 21 is arranged in the first weight reduction structure, and the rigidity of the anti-collision beam body 2 can be improved on the premise of ensuring the lightweight of the anti-collision body, so as to ensure that the damage to the frame caused by the collision force of the automobile is reduced during the collision process.
[0024] Among them, the first weight reduction structure is a receiving groove 22, and a plurality of first support members 21 are arranged in the receiving groove 22. The receiving groove 22 is opened on the anti-collision beam body 2 along the extension direction of the anti-collision beam body 2, and each first support member 21 is arranged in sequence along the extension direction of the receiving groove 22. By setting the receiving groove 22, the weight of the anti-collision beam body 2 can be reduced, and the manufacturing cost of the anti-collision beam body 2 can also be saved. The receiving groove 22 has a simple structure and is easy to produce and manufacture. By setting at least two first support members 21 in the receiving groove 22, it is possible to ensure that the rigidity of the anti-collision beam body 2 meets the anti-collision requirements while ensuring the lightweight of the anti-collision beam body 2. In some embodiments, the first weight reduction structure can also be a receiving hole opened in sequence along the extension direction of the anti-collision beam body 2. In other embodiments, the first weight reduction structure can also be a receiving depression arranged on the anti-collision beam body 2. The type of the first weight reduction structure can be adjusted according to actual needs.
[0025] Specifically, the first support member 21 is in a long strip shape, and two adjacent first support members 21 are arranged in a V shape. Through the first support member 21, while ensuring the lightweight of the anti-collision beam body 2, the overall strength of the anti-collision beam body 2 is further increased.
[0026] The automobile anti-collision beam further comprises a mounting base 1 and an energy absorption box 4, one end of the energy absorption box 4 is connected to the mounting base 1, the anti-collision beam body 2 is arranged on the other end of the energy absorption box 4 and connected to the mounting base 1 through the energy absorption box 4, and a buffer support 5 is also arranged between the mounting base 1 and the anti-collision beam body 2, the buffer support 5 is a frame structure, and the buffer support 5 is supported between the mounting base 1 and the anti-collision beam body 2. By arranging the buffer support 5 between the mounting base 1 and the anti-collision beam body 2, the support for the anti-collision beam body 2 can be strengthened. At the same time, when the automobile is subjected to a strong impact, the buffer distance of the automobile anti-collision beam can be increased, and on the basis of the energy absorption box 4, the buffer performance of the automobile anti-collision beam is strengthened, so that the automobile anti-collision beam has multiple impact resistance and buffering capabilities.
[0027] Specifically, the buffer support 5 includes a supporting transverse plate 51, and the side surface of one side of the supporting transverse plate 51 is in contact with the mounting surface, and the buffer support 5 supports the anti-collision beam body 2 through the supporting transverse plate 51. The side surface of one side of the supporting transverse plate 51 is in contact with the mounting surface, which increases the strength of the anti-collision beam body 2 and increases the contact area between the buffer support 5 and the anti-collision beam body 2. When the car is hit, it is avoided that the collision force is transmitted from the anti-collision beam body 2 to the buffer support 5. The process of generating a stress concentration point can improve the overall buffering and impact resistance of the buffer support 5.
[0028] In this embodiment, the buffer support 5 further includes a first connecting rod 54, a second connecting rod 55, and two first supporting side plates 52 and second supporting side plates 53 arranged at intervals. The first supporting side plates 52 and the second supporting side plates 53 are both supported between the supporting transverse plate 51 and the mounting base 1. The first ends of the first supporting side plates 52 and the second supporting side plates 53 are both connected to the supporting transverse plate 51, and the second ends of the first supporting side plates 52 and the second supporting side plates 53 are both connected to the mounting base 1. The first connecting rod 54 and the second connecting rod 55 are cross-arranged between the first supporting side plates 52 and the second supporting side plates 53. The first ends of the first connecting rod 54 and the second connecting rod 55 are both connected to the supporting transverse plate 51, and the second ends of the second connecting rod 55 are connected to the second end of the first supporting side plates 52, and the second ends of the first connecting rod 54 are connected to the second end of the second supporting side plates 53. The first supporting side plates 52 and the second supporting side plates 53 are used to support the transverse plate 51 to increase the impact resistance of the supporting transverse plate 51. The supporting structure is simple and easy to produce and assemble. By providing the first connecting rod 54 and the second connecting rod 55, the lateral anti-collision buffering effect of the automobile anti-collision beam can be enhanced, thereby improving the stability, compression resistance and impact resistance of the buffer support 5. In some embodiments, the supporting side plate can be replaced by a spring telescopic rod, a hydraulic telescopic rod, etc. The type of the supporting side plate can be adjusted according to actual needs.
[0029] In detail, the anti-collision beam body 2 has an anti-collision direction perpendicular to the extension direction of the anti-collision beam body 2. In the anti-collision direction, there is a buffer gap between the buffer support 5 and the mounting base 1. A plurality of energy absorbing tubes 57 are arranged in the buffer gap. The axial direction of the energy absorbing tube 57 is perpendicular to the anti-collision direction. Each energy absorbing tube 57 is arranged in sequence along the extension direction of the anti-collision beam body 2. By providing the energy absorbing tube 57, the buffering performance of the buffer support 5 can be further improved. When the car suffers a severe collision, the plurality of energy absorbing tubes 57 can provide buffering for the buffer support 5. In this embodiment, the energy absorbing tube 57 is made of metal.
[0030] In this embodiment, a partition 58 is provided between two adjacent energy absorbing tubes 57. The partition 58 extends in the anti-collision direction, and both sides of the partition 58 are respectively in contact with the adjacent energy absorbing tubes 57. When the car is severely impacted, the energy absorbing tube 57 may be deformed under the extrusion, thereby extruding the partition 58. In the process of being extruded, the partition 58 can increase the support for the buffer support member 5, further improving the buffering and anti-collision effect of the anti-collision beam of the car.
[0031] In this embodiment, the buffer support member 5 further includes a fixing plate 56, a buffer gap is formed between the fixing plate 56 and the mounting base 1, the supporting transverse plate 51 is connected to the anti-collision beam body 2 by bolts, the first connecting rod 54 and the second connecting rod 55 are respectively welded to the fixing plate 56 and the supporting transverse plate 51 at both ends, the first supporting side plate 52 and the second supporting side plate 53 are both connected to the mounting base 1 by bolts at one end, and the first supporting side plate 52 and the second supporting side plate 53 are welded to the supporting transverse plate 51 at the other end. The partition plate 58 is welded to the fixing plate 56, and the side of the partition plate 58 away from the fixing plate 56 is in contact with the mounting base 1, and the energy absorbing tube 57 is connected to the fixing plate 56 by bolts, and the energy absorbing tube 57 is in contact with the mounting base 1.
[0032] In detail, the energy absorbing tube 57 has an extension direction, which is perpendicular to the anti-collision direction and the length direction of the energy absorbing tube 57. The dimension of the longitudinal section of the energy absorbing tube 57 in the extension direction is greater than the dimension of the longitudinal section of the energy absorbing tube 57 in the anti-collision direction. The energy absorbing tube 57 can provide collision protection for the buffer support 5 to a certain extent. When the energy absorbing tube 57 is compressed, the energy absorbing tube 57 will deform along the extension direction. At the same time, the energy absorbing tube 57 squeezes the partitions 58 on both sides to provide lateral support force for the partitions 58. Therefore, the partitions 58 can provide better support for the fixing plate 56, and further provide collision protection for the buffer support 5.
[0033] Among them, two energy absorption boxes 4 are arranged on the anti-collision beam of the automobile, and the two energy absorption boxes 4 are respectively arranged at the two ends of the anti-collision beam body 2. The energy absorption box 4 includes an energy absorption box body 43, a support tube 42 and a box bottom plate 41. The energy absorption box body 43 has a cavity for placing the support tube 42, and a plurality of support tubes 42 perpendicular to the box bottom plate 41 are arranged in the cavity. The energy absorption box 4 supports the support tube 42 in the axial direction of the support tube 42 in the cavity of the energy absorption box body 43 through the box bottom plate 41. The side of one side of the box bottom plate 41 is against one end of the support tube 42, and the side of the other side of the box bottom plate 41 is in contact with the mounting base. The energy absorption box body 43 and the box bottom plate 41 are fixed by bolts. When the collision force acts on the energy absorption box 4, the energy absorption box 4 is supported by the plurality of support tubes 42, and collision protection can be provided for the anti-collision beam body 2.
[0034] In this embodiment, a reinforcing plate 3 is provided on the collision surface of the anti-collision beam body 2, and the side surface of the reinforcing plate 3 close to the side of the anti-collision beam body 2 is in contact with the collision surface and welded to the collision surface. A plurality of reinforcing ribs are provided on the reinforcing plate 3, each of which is arc-shaped and in contact with the reinforcing plate 3. The reinforcing ribs can increase the strength of the reinforcing plate 3 and improve the rigidity and anti-collision performance of the anti-collision beam body 2.
[0035] From the above, we can see that the collision protection principle of the car anti-collision beam is as follows:
[0036] When the car is hit, the reinforcing plate 3 provides the first layer of collision protection for the car, and the anti-collision beam body 2 and the first weight reduction structure in the anti-collision beam body 2 provide the second layer of collision protection for the car. When the anti-collision beam body 2 causes a collision, the impact force will be transmitted to the energy absorption box 4 and the buffer support 5. The energy absorption box 4 provides the third layer of collision protection for the car, and the connecting rod on the buffer support 5 provides the fourth layer of collision protection for the car. When the energy absorption tube 57 is subjected to impact force, it can support the fixed plate 56. At the same time, when the energy absorption tube 57 is squeezed, the impact force is converted into the squeezing force of the squeezing partition 58, providing the fifth layer of collision protection for the car. Providing multiple layers of collision protection for the car through the anti-collision beam of the car can ensure the safety of the car during driving to the greatest extent, and avoid excessive damage to the car during the collision, which endangers the life safety of the driver and passengers.
[0037] In summary, by setting the first weight-reducing structure on the anti-collision body, the weight of the anti-collision beam body 2 can be reduced, the raw materials for producing the anti-collision beam body 2 can be saved, and the production cost can be reduced. The first support member 21 is set in the first weight-reducing structure, and the rigidity of the anti-collision beam body 2 can be ensured under the premise of ensuring the lightweight of the anti-collision body, so as to ensure that the damage to the frame caused by the collision force is reduced during the collision of the car.
