Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a bumper beam assembly and a vehicle. Background Art

[0002] In the prior art, the bumper beam assembly can generally bear a vehicle with a maximum weight of 3 tons during the towing process. When the weight of the vehicle exceeds 3 tons, the traditional bumper beam assembly generally cannot meet the towing requirements of a vehicle weighing more than 3 tons. Moreover, some strengthen the plate inside the outer plate of the bumper beam, but the strengthened plate is arranged in a local area of the towing installation position, resulting in insufficient strength and easy stress concentration in the towing area, leading to tearing of the bumper beam assembly. Content of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a bumper beam assembly, which can avoid the force being concentrated in a local area of the towing installation position. The outer plate strengthening plate can directly disperse the received force to both ends in the length direction of the bumper beam outer plate, make the overall force of the bumper beam outer plate and the outer plate strengthening plate more uniform, and prevent the non-towing area of the bumper beam outer plate from deforming, thereby further improving the strength and stiffness of the bumper beam assembly.

[0004] The utility model further provides a vehicle.

[0005] The bumper beam assembly according to the first aspect embodiment of the utility model includes: a bumper beam outer plate; an outer plate strengthening plate, which is arranged inside the bumper beam outer plate and extends along the length direction of the bumper beam outer plate; wherein, the length of the outer plate strengthening plate is L1, the length of the bumper beam outer plate is L2, and L1 and L2 satisfy the relational expression: L1≥0.5L2.

[0006] Therefore, in the bumper beam assembly 100, the length L1 of the outer plate strengthening plate 20 is not less than half of the length L2 of the bumper beam outer plate 10. When towing a vehicle weighing more than 3 tons, not only does the middle part of the outer plate strengthening plate 20 contact and cooperate with the middle part of the bumper beam outer plate 10, but also the two sides in the length direction of the outer plate strengthening plate 20 are stacked with the two sides in the length direction of the bumper beam outer plate 10. The force received by the bumper beam outer plate 10 in the towing area can be attenuated by transmitting the force to both ends in the length direction of the outer plate strengthening plate 20 through the outer plate strengthening plate 20. The two sides in the length direction of the outer plate strengthening plate 20 are directly connected and cooperated with the two sides in the length direction of the bumper beam outer plate 10. In this way, the outer plate strengthening plate 20 further transmits the attenuated force to both sides in the length direction of the bumper beam outer plate 10 for further dispersion, reducing the local force and avoiding the force being concentrated in a local area of the towing installation position, thereby preventing the non-towing area of the bumper beam outer plate 10 from deforming.

[0033] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present utility model will be described in detail below.

[0034] Reference will be made below Figures 1-7 to describe the anti-collision beam assembly 100 according to an embodiment of the present utility model.

[0035] Referring to Figure 2 and Figure 7 as shown, the anti-collision beam assembly 100 of the first aspect embodiment of the present utility model includes: an outer anti-collision beam plate 10 and an outer plate reinforcement 20. The outer plate reinforcement 20 is disposed inside the outer anti-collision beam plate 10, and the outer plate reinforcement 20 extends along the length direction of the outer anti-collision beam plate 10. Among them, the length of the outer plate reinforcement 20 is L1, and the length of the outer anti-collision beam plate 10 is L2. The relationship satisfied by L1 and L2 is: L1≥0.5L2.

[0036] Specifically, the anti-collision beam assembly 100 can be used as the front anti-collision beam assembly of a vehicle or as the rear anti-collision beam assembly of a vehicle.

[0037] In the process of towing a vehicle, a traditional anti-collision beam assembly can generally bear a vehicle with a maximum weight of 3 tons. When the weight of the vehicle exceeds 3 tons, the traditional anti-collision beam assembly generally cannot meet the towing requirements of a vehicle with a weight exceeding 3 tons. Moreover, some are provided with a reinforcement plate inside the outer anti-collision beam plate, but the reinforcement plate is provided in a local area of the towing installation position, resulting in insufficient strength and is also prone to stress concentration in the towing area, causing the anti-collision beam assembly to tear.

[0038] Therefore, it is necessary to optimize the design of the anti-collision beam assembly 100. The outer plate reinforcement 20 in the anti-collision beam assembly 100 is disposed inside the outer anti-collision beam plate 10, thereby improving the overall strength and stiffness of the outer anti-collision beam plate 10. Moreover, the outer plate reinforcement 20 extends along the length direction of the outer anti-collision beam plate 10. That is to say, the outer plate reinforcement 20 is not only connected and matched with the towing area of the outer anti-collision beam plate 10, but also connected and matched with other areas in the length direction of the outer anti-collision beam plate 10.

[0039] Furthermore, a vehicle designed with the length L1 of the outer plate reinforcement 20 not less than half of the length L2 of the outer anti-collision beam plate 10 is compared with a vehicle designed with the length L1 of the outer plate reinforcement 20 less than half of the length L2 of the outer anti-collision beam plate 10 to analyze the damage degree of towing a vehicle exceeding 3 tons.

[0040] Three vehicle structures are modeled through finite element simulation to simulate the towing scenario and analyze the influence of vehicles with the length L1 of the outer panel reinforcement plate 20 being half of the length L2 of the outer panel of the bumper beam, vehicles with the length L1 of the outer panel reinforcement plate 20 being not less than half of the length L2 of the outer panel of the bumper beam, and vehicles with the length L1 of the outer panel reinforcement plate 20 being less than half of the length L2 of the outer panel of the bumper beam on the structural strength and energy absorption of the bumper beam assembly 100.

[0041] By comparing different stress distributions and deformation conditions, when the length L1 of the outer panel reinforcement plate 20 is less than half of the length L2 of the outer panel of the bumper beam, during the towing test, the length L1 of the outer panel reinforcement plate 20 is shorter, and the force is mainly concentrated in the middle of the outer panel of the bumper beam. Since the strength of the local area where the outer panel reinforcement plate 20 contacts the outer panel of the bumper beam is relatively high, it causes the other areas where the outer panel of the bumper beam 10 contacts the outer panel reinforcement plate 20 to bend when subjected to tensile force, resulting in a relatively large stress and a relatively large deformation degree on the outer panel of the bumper beam 10.

[0042] When the length L1 of the outer panel reinforcement plate 20 is set to be half of the length L2 of the outer panel of the bumper beam, not only does the outer panel reinforcement plate 20 contact and cooperate with the middle of the outer panel of the bumper beam, but also the two sides in the length direction of the outer panel reinforcement plate 20 are stacked with the two sides in the length direction of the outer panel of the bumper beam. During towing, the force received by the outer panel of the bumper beam 10 in the towing area can be attenuated by transmitting the force through the outer panel reinforcement plate 20 to the two ends in the length direction of the outer panel reinforcement plate 20. Since the outer panel reinforcement plate 20 extends along the length direction of the outer panel of the bumper beam 10 and the two sides in the length direction of the outer panel reinforcement plate 20 are directly connected and cooperate with the two sides in the length direction of the outer panel of the bumper beam 10, in this way, the outer panel reinforcement plate 20 further transmits the attenuated force to the two sides in the length direction of the outer panel of the bumper beam 10 for further dispersion, reducing the local force, avoiding the force being concentrated in the local area of the towing installation position, increasing the contact area between the outer panel of the bumper beam 10 and the outer panel reinforcement plate 20, and making the overall force on the outer panel of the bumper beam 10 and the outer panel reinforcement plate 20 more uniform, thereby preventing the non-towing area of the outer panel of the bumper beam 10 from deforming. The test results show that the stress on the outer panel of the bumper beam 10 is relatively small and the deformation degree is relatively small, thus verifying the effectiveness of the design.

[0043] When the length L1 of the outer panel reinforcement plate 20 is set to be greater than half of the length L2 of the outer panel of the bumper beam, the stress on the outer panel of the bumper beam 10 is smaller and the deformation degree is smaller, thus verifying the effectiveness of the design.

[0044] Moreover, tensile, compression, and impact tests are carried out on the outer panel reinforcement plate 20 and the outer panel of the bumper beam of the three vehicles to evaluate their strength performance during towing. The bumper beam assembly 100 of the vehicle with the length L1 of the outer panel reinforcement plate 20 being not less than half of the length L2 of the outer panel of the bumper beam meets the strength requirements.

[0045] Moreover, the length L1 of the outer panel reinforcement plate 20 is not greater than the length L2 of the outer panel 10 of the bumper beam. In this way, the length of the outer panel reinforcement plate 20 can be shortened, thereby effectively reducing the overall weight of the vehicle, improving fuel economy and handling performance, and also reducing the use of materials, thus reducing production costs.

[0046] Therefore, in the bumper beam assembly 100, the length L1 of the outer panel reinforcement plate 20 is not less than half of the length L2 of the outer panel 10 of the bumper beam. When towing a vehicle weighing more than 3 tons, not only does the middle part of the outer panel reinforcement plate 20 come into contact and cooperate with the middle part of the outer panel 10 of the bumper beam, but also the two sides in the length direction of the outer panel reinforcement plate 20 are stacked with the two sides in the length direction of the outer panel 10 of the bumper beam. The force received by the outer panel 10 of the bumper beam in the towing area can be attenuated by transmitting the force through the outer panel reinforcement plate 20 to both ends in the length direction of the outer panel reinforcement plate 20. The two sides in the length direction of the outer panel reinforcement plate 20 are directly connected and cooperate with the two sides in the length direction of the outer panel 10 of the bumper beam. In this way, the outer panel reinforcement plate 20 further transmits the attenuated force to both sides in the length direction of the outer panel 10 of the bumper beam for further dispersion, reducing the local force and preventing the non-towing area of the outer panel 10 of the bumper beam from deforming.

[0047] According to some embodiments of the present invention, as Figure 2 shown, the outer panel reinforcement plate 20 is correspondingly located in the middle of the outer panel 10 of the bumper beam, and the distance from the left end of the outer panel reinforcement plate 20 to the left end of the outer panel 10 of the bumper beam is the same as the distance from the right end of the outer panel reinforcement plate 20 to the right end of the outer panel 10 of the bumper beam.

[0048] Among them, since the force on the middle part of the outer panel 10 of the bumper beam is relatively large, the outer panel reinforcement plate 20 is correspondingly located in the middle of the outer panel 10 of the bumper beam. In this way, sufficient strength and stiffness can be ensured in the middle part of the outer panel 10 of the bumper beam.

[0049] Furthermore, the distance from the left end of the outer panel reinforcement plate 20 to the left end of the outer panel 10 of the bumper beam is the same as the distance from the right end of the outer panel reinforcement plate 20 to the right end of the outer panel 10 of the bumper beam. In this way, the outer panel reinforcement plate 20 is symmetrically arranged, so that the force transmission between the outer panel 10 of the bumper beam and the outer panel reinforcement plate 20 can be made more uniform.

[0050] According to some embodiments of the present invention, as Figure 2 and Figure 4 shown, the outer panel reinforcement plate 20 includes: a first main board 21 and a first side board 22. The first main board 21 is arranged in the middle of the inner side of the outer panel 10 of the bumper beam, and the first side boards 22 are respectively connected to both sides of the first main board 21. The first side boards 22 are provided with bosses 221, and the bosses 221 protrude forward.

[0051] Among them, the outer plate reinforcement plate 20 is mainly composed of a first main plate 21 and a first side plate 22. The first main plate 21 is located in the middle of the inner side of the outer plate 10 of the bumper beam. When the bumper beam assembly 100 is subjected to a towing force, the outer plate 10 of the bumper beam and the first main plate 21 can jointly bear the towing force, so as to reduce the overall force on the bumper beam assembly 100.

[0052] Furthermore, the first side plate 22 is provided with a boss 221 which protrudes forward, that is, the boss 221 protrudes towards the inner side of the first side plate 22. The setting of the boss 221 can effectively disperse the externally applied pressure and impact force, reduce the local concentrated force, and thus improve the durability of the outer plate reinforcement plate 20.

[0053] Moreover, a cavity is formed between the inner wall of the boss 221 and the inner surface of the outer plate 10 of the bumper beam. In this way, the strength of the first side plate 22 and the outer plate 10 of the bumper beam can be further improved, and the anti-deformation ability between the first side plate 22 and the outer plate 10 of the bumper beam can also be improved.

[0054] According to some embodiments of the present invention, a strength weakening portion 222 is provided on one side of the boss 221.

[0055] Among them, the strength weakening portion 222 can locally weaken its own stiffness, thereby enhancing the fatigue strength of the weld bead between the outer plate reinforcement plate 20 and the outer plate 10 of the bumper beam.

[0056] According to some embodiments of the present invention, as Figure 4 shown, the strength weakening portion 222 is configured as a notch recessed from the side of the first side plate 22 towards the first main plate 21.

[0057] Among them, the strength weakening portion 222 is set as a notch, and the notch is U-shaped, which can not only facilitate the welding of the outer plate reinforcement plate 20 and the outer plate 10 of the bumper beam, but also enhance the fatigue strength of the weld bead between the outer plate reinforcement plate 20 and the outer plate 10 of the bumper beam.

[0058] According to some embodiments of the present invention, as Figure 3 and Figure 7 shown, the bumper beam assembly 100 further includes: an inner plate 30 of the bumper beam and an inner plate reinforcement plate 40. The inner plate 30 of the bumper beam is disposed opposite to the outer plate 10 of the bumper beam, and the inner plate 30 of the bumper beam is located in front of the outer plate 10 of the bumper beam. The inner plate reinforcement plate 40 is located between the outer plate reinforcement plate 20 and the inner plate 30 of the bumper beam, and the inner plate reinforcement plate 40 is welded to the inner plate 30 of the bumper beam.

[0059] Specifically, the inner plate 30 of the bumper beam and the inner plate reinforcement plate 40 are disposed opposite to each other, and the inner plate reinforcement plate 40 can improve the strength of the inner plate 30 of the bumper beam.

[0060] The inner panel 30 of the bumper beam is located in front of the outer panel 10 of the bumper beam, that is, the inner panel 30 of the bumper beam is arranged inside the outer panel 10 of the bumper beam. One side of the inner panel reinforcement plate 40 is connected to the outer panel reinforcement plate 20, and the other side of the inner panel reinforcement plate 40 is welded to the inner panel 30 of the bumper beam. In this way, the outer panel 10 of the bumper beam, the outer panel reinforcement plate 20, the inner panel reinforcement plate 40 and the inner panel 30 of the bumper beam can form a whole. When the outer panel 10 of the bumper beam is subjected to a towing force, the towing force received by the outer panel 10 of the bumper beam can be first transmitted and dispersed through the outer panel reinforcement plate 20. Since the outer panel reinforcement plate 20 is also connected to the inner panel reinforcement plate 40 through the support column 61, the force on the outer panel reinforcement plate 20 can be dispersed to the inner panel reinforcement plate 40. The inner panel reinforcement plate 40 is welded to the inner panel 30 of the bumper beam, and the force received by the inner panel reinforcement plate 40 can be dispersed to the inner panel 30 of the bumper beam, thereby gradually attenuating the force on the bumper beam assembly 100.

[0061] According to some embodiments of the present invention, as Figure 5 and Figure 7 shown, the inner panel reinforcement plate 40 includes: a second main board 41 and second side boards 42. The outer side of the second main board 41 is connected to the outer panel reinforcement plate 20, and the inner side of the second main board 41 is plug-welded to the inner panel 30 of the bumper beam. The second side boards 42 are respectively connected to both sides of the second main board 41, and the second side boards 42 are bent forward relative to the second main board 41, and the second side boards 42 are welded to the inner panel 30 of the bumper beam.

[0062] Wherein, the outer side of the second main board 41 is connected to the outer panel reinforcement plate 20 through the support column 61, which can improve the strength between the second main board 41 and the outer panel reinforcement plate 20. The inner side of the second main board 41 is plug-welded to the inner panel 30 of the bumper beam, which can make the connection between the second main board 41 and the inner panel 30 of the bumper beam more stable and firm.

[0063] In addition, the second side boards 42 are respectively connected to both sides of the second main board 41, which is convenient for plug-welding the second side boards 42 to both sides in the length direction of the inner panel 30 of the bumper beam, so that the connection between the second side boards 42 and the inner panel 30 of the bumper beam can be more stable and firm.

[0064] Furthermore, as Figure 7 shown, a protrusion 60 is provided in the middle of the second main board 41. The protrusion 60 protrudes towards the inner panel 30 of the bumper beam, and the protrusion 60 is welded to the inner panel 30 of the bumper beam, which can further improve the strength between the inner panel reinforcement plate 40 and the inner panel 30 of the bumper beam, and can also further make the connection between the inner panel reinforcement plate 40 and the inner panel 30 of the bumper beam more stable and firm.

[0065] According to some embodiments of the present invention, as Figure 1As shown, the inner panel 30 of the bumper beam is provided with plug weld holes 31. The height of the plug weld hole 31 is h, and h satisfies the relation: h≥64 mm, and / or the width of the plug weld hole 31 is w, and w satisfies the relation: w≥24 mm.

[0066] Wherein, to further make the connection between the inner panel 30 of the bumper beam and the inner panel reinforcement plate 40 more stable and firm, the hole positions within the drag force center area of the inner panel 30 of the bumper beam are removed, and the inner panel 30 of the bumper beam is welded and connected to the inner panel reinforcement plate 40 through the plug weld holes 31.

[0067] Moreover, the shape of the plug weld hole 31 is strip-shaped. Specifically, it is a rectangle in the middle and two semi-circles at the upper and lower ends.

[0068] When the height of the plug weld hole 31 is set less than 64 mm, for example, when the height of the plug weld hole 31 is set to 63 mm, it will cause the stress at the connection part in the height direction of the plug weld hole 31 to be concentrated, increasing the risk of fatigue damage to the material and also increasing the risk of porosity and inclusions generated during welding.

[0069] When the height h of the plug weld hole 31 is set not less than 64 mm, the larger height of the plug weld hole 31 can increase the contact surface of the welding area, can also enhance the welding strength, better exhaust during the welding process, reduce the occurrence of welding defects such as porosity and inclusions, and thus can improve the welding quality.

[0070] In addition, when the width of the plug weld hole 31 is set less than 24 mm, for example, when the width of the plug weld hole 31 is set to 23 mm, the welding area in the width direction of the plug weld hole 31 is small, and the plug weld hole 31 is prone to looseness in the width direction.

[0071] Therefore, setting the width w of the plug weld hole 31 not less than 24 mm can increase the welding area in the width direction of the plug weld hole 31, can also prevent the plug weld hole 31 from loosening in the width direction, so that the connection between the inner panel 30 of the bumper beam and the inner panel reinforcement plate 40 can be made more firm, and can also improve the connection strength between the inner panel 30 of the bumper beam and the inner panel reinforcement plate 40.

[0072] According to some embodiments of the present invention, as Figure 1 and Figure 6 shown, the bumper beam assembly 100 further includes: a longitudinal beam connecting plate 50. The longitudinal beam connecting plate 50 is disposed on the outer panel 10 of the bumper beam. Wherein, the longitudinal beam connecting plate 50 is plug-welded to the outer panel 10 of the bumper beam, and / or the wall thickness of the longitudinal beam connecting plate 50 is a, and a satisfies the relation: a≥3.5 mm.

[0073] Among them, the longitudinal beam connecting plate 50 is plug-welded to the outer bumper beam plate 10, which can further improve the strength of the outer bumper beam plate 10. The outer plate reinforcement plate 20 is extended to a length not less than half of the total length of the outer bumper beam plate 10, so that the force at the towing installation point can be dispersed to both sides of the outer bumper beam plate 10, instead of concentrating on a local area. Moreover, the wall thickness of the longitudinal beam connecting plate 50 is not less than 3.5 mm. When the wall thickness of the longitudinal beam connecting plate 50 is set less than 3.5 mm, for example, when the wall thickness of the longitudinal beam connecting plate 50 is set to 3 mm, during towing, the longitudinal beam connecting plate 50 undergoes a small deformation, and the strength of the overlapping area between the longitudinal beam connecting plate 50 and the outer bumper beam plate 10 is small. Therefore, setting the wall thickness of the longitudinal beam connecting plate 50 not less than 3.5 mm can enhance the strength of the buffer area between the towing installation area of the outer bumper beam plate 10 and the overlapping area of the longitudinal beam connecting plate 50.

[0074] The vehicle according to the second aspect embodiment of the present invention includes: the bumper beam assembly 100 of the above embodiment.

[0075] The bumper beam assembly 100 can prevent the force received from concentrating on a local area of the towing installation position, and can gradually disperse the force received through the outer plate reinforcement plate 20, the inner plate reinforcement plate 40, the inner bumper beam plate 30, and the longitudinal beam connecting plate 50, so as to ensure that the bumper beam assembly 100 has sufficient strength and can also meet the towing requirements of vehicles weighing more than 3 tons.
