Description

Technical Field

[0002] Vehicles are becoming more and more indispensable means of transportation in people's daily lives, and vehicle collision safety is one of the important indicators to measure vehicle performance. The vehicle's front anti-collision beam assembly is often located in the front cabin of the vehicle. It can absorb energy in the event of a low-speed collision and protect the water tank and other vehicles behind it from damage; in the event of a high-speed collision, it can effectively transfer energy to the entire vehicle body, thereby ensuring the safety of the vehicle's drivers and passengers.

[0003] When the anti-collision beam assembly is hit by a collision, the energy is mainly absorbed by the collapse of the energy absorption box. However, in the related technology, the connection strength between the energy absorption box and the anti-collision beam of the anti-collision beam assembly is relatively poor. When the energy absorption box collapses and deforms, the connection between the energy absorption box and the anti-collision beam is prone to simultaneous tearing, thereby affecting the energy absorption stability of the anti-collision beam assembly during the entire collision process.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] Combine the following Figure 1-Figure 5 The anti-collision beam assembly according to the embodiment of the utility model is described.

[0032] The anti-collision beam assembly of the embodiment of the utility model includes an anti-collision beam 1, an energy absorption box 2 and a reinforcement plate. The energy absorption box 2 includes a top plate 21, a first side plate 22, a bottom plate 23 and a second side plate 24 connected end to end and extending along a first direction. The top plate 21 includes a first connecting plate 211 protruding from the first end surface of each of the first side plate 22 and the second side plate 24 in the first direction, and the bottom plate 23 includes a second connecting plate 231 protruding from the first end surface of each of the first side plate 22 and the second side plate 24 in the first direction. The first connecting plate 211 and the second connecting plate 231 are both connected to the anti-collision beam 1 and are respectively arranged on two opposite sides of the anti-collision beam 1 in the second direction, and the second direction is perpendicular to the first direction. The reinforcement plate is connected to at least one of the first connecting plate 211 and the second connecting plate 231.

[0033] According to the anti-collision beam assembly of the embodiment of the utility model, the energy absorption box 2 is connected to the anti-collision beam 1 through the first connecting plate 211 and the second connecting plate 231, wherein a reinforcing plate is provided to be connected to at least one of the first connecting plate 211 and the second connecting plate 231. With the support of the reinforcing plate, the structural strength of the connection between at least one of the first connecting plate 211 and the second connecting plate 231 and the anti-collision beam 1 is effectively improved. Therefore, when the anti-collision beam 1 is collided and the energy absorption box 2 is collapsed and deformed, the first connecting plate 211 and the second connecting plate 231 are less likely to tear, thereby effectively ensuring the energy absorption stability of the energy absorption box 2.

[0034] It should be noted that after the anti-collision beam 1 is connected to each of the first connecting plate 211 and the second connecting plate 231, it is also in contact with the first end surface of the first side plate 22 and the second side plate 24, thereby ensuring that the energy absorption box 2 can also directly withstand the impact from the first side plate 22 and the second side plate 24. The first direction is the length direction of the energy absorption box 2, which is also the length direction of the vehicle, and the second direction is the height direction of the anti-collision beam 1 and the vehicle. At this time, by setting a reinforcing plate, there is no need to perform additional thickening design on the first connecting plate 211 and the second connecting plate 231, which reduces the difficulty and cost of manufacturing the energy absorption box 2.

[0035] For ease of understanding, Figure 1 The direction indicated by the middle arrow X is the first direction of the anti-collision beam assembly according to the embodiment of the utility model. Figure 1 The direction indicated by the middle arrow Z is the second direction of the anti-collision beam assembly according to the embodiment of the utility model. Figure 1 The direction indicated by the middle arrow Y is the third direction of the anti-collision beam assembly according to the embodiment of the utility model.

[0036] In some embodiments, Figure 4 and Figure 5 As shown, the reinforcing plate includes a first reinforcing plate 3 and a second reinforcing plate 4 , at least part of the first reinforcing plate 3 is connected between the first connecting plate 211 and the anti-collision beam 1 , and at least part of the second reinforcing plate 4 is connected between the second connecting plate 231 and the anti-collision beam 1 .

[0037] The first reinforcing plate 3 and the second reinforcing plate 4 respectively reinforce the strength of the first connecting plate 211 and the second connecting plate 231 of the energy absorbing box 2, thereby further improving the tearing strength between the energy absorbing box 2 and the anti-collision beam 1, and the energy absorption stability of the energy absorbing box 2 is higher.

[0038] Specifically, the first reinforcing plate 3 is in close contact with each of the first connecting plate 211 and the anti-collision beam 1, and the contact area between the first reinforcing plate 3 and the first connecting plate 211 is approximately equal to the area of ​​the lower surface of the first connecting plate 211. The second reinforcing plate 4 is in close contact with each of the second connecting plate 231 and the anti-collision beam 1, and the contact area between the second reinforcing plate 4 and the second connecting plate 231 is approximately equal to the area of ​​the upper surface of the second connecting plate 231.

[0039] In some embodiments, the first connecting plate 211 is provided with first flanges 212 extending along the second direction toward the anti-collision beam 1 at both opposite ends along the third direction, the two first flanges 212 are connected to the first side plate 22 and the second side plate 24 respectively, the size of the first flanges 212 in the second direction is less than or equal to the thickness of the first reinforcing plate 3, and the third direction, the second direction and the first direction are perpendicular to each other. And / or, the second connecting plate 231 is provided with second flanges 232 extending along the second direction toward the anti-collision beam 1 at both opposite ends along the third direction, the two second flanges 232 are connected to the first side plate 22 and the second side plate 24 respectively, the size of the second flanges 232 in the second direction is less than or equal to the thickness of the second reinforcing plate 4, and the third direction, the second direction and the first direction are perpendicular to each other.

[0040] The design of the first flange 212 effectively improves the bending strength between the first connecting plate 211 and other parts of the energy absorbing box 2. The design of the second flange 232 effectively improves the bending strength between the second connecting plate 231 and other parts of the energy absorbing box 2. At this time, when the anti-collision beam 1 is collided, the first connecting plate 211 and the second connecting plate 231 are less likely to bend relative to other parts of the energy absorbing box 2. The structural integrity of the energy absorbing box 2 is better and the energy absorption stability is higher.

[0041] By setting the dimensions of the first flange 212 and the second flange 232 in the second direction to be smaller than the thickness of the first reinforcing plate 3 and the second reinforcing plate 4, it is avoided that the first flange 212 and the second flange 232 contact the anti-collision beam 1, thereby causing the first reinforcing plate 3 and the second reinforcing plate 4 to have poor contact with the anti-collision beam 1.

[0042] like Figure 4 and Figure 5 As shown, the length of the first flange 212 in the first direction is equal to the length of the first connecting plate 211 in the first direction, and the length of the second flange 232 in the first direction is equal to the length of the second connecting plate 231 in the first direction.

[0043] In some embodiments, Figure 1 , Figure 2 and Figure 4As shown, a first collapse groove 27 is provided at the connection between the first side plate 22 and the top plate 21, and the width direction of the first collapse groove 27 is consistent with the first direction, and / or a second collapse groove 28 is provided at the connection between the first side plate 22 and the bottom plate 23, and the width direction of the second collapse groove 28 is consistent with the first direction. The anti-collision beam assembly also includes a third reinforcement plate, which is connected to the second side plate 24, and the third reinforcement plate is located on the side of the second side plate 24 facing the first side plate 22, and the third reinforcement plate is connected to at least one of the first reinforcement plate 3 and the second reinforcement plate 4.

[0044] When the anti-collision beam 1 is hit so that the impact force is transmitted to the energy absorption box 2, the energy absorption box 2 first collapses and disappears at the first collapse groove 27 and / or the second collapse groove 28, so that the length of at least one of the two opposite sides in the second direction of the first side plate 22 of the energy absorption box 2 collapses and shrinks, thereby realizing the energy absorption function. In this process, by setting the third reinforcing plate 5 connected to the second side plate 24 and connected to at least one of the first reinforcing plate 3 and the second reinforcing plate 4, the structural strength of the second side plate 24 is effectively improved, and the second side plate 24 is effectively prevented from being deformed when impacted by the anti-collision beam 1, resulting in tearing at the connection between the second side plate 24 and the top plate 21 and the bottom plate 23, thereby ensuring the structural integrity and energy absorption stability of the energy absorption box 2.

[0045] Specifically, a first collapse groove 27 is provided at the connection between the first side plate 22 and the top plate 21 , and a second collapse groove 28 is provided at the connection between the first side plate 22 and the bottom plate 23 . The width directions of the first collapse groove 27 and the second collapse groove 28 are consistent with the first direction.

[0046] It should be noted that, taking the front anti-collision beam 1 set in the front cabin as an example, the anti-collision beam 1 is an arc-shaped beam with the middle part bent forward. The first end face of the first side panel 22 of the energy absorption box 2 protrudes from the second end face of the second side panel 24 along the direction from the energy absorption box 2 to the anti-collision beam 1, and the first side panel 22 is located on the side of the center line of the second side panel 24 extending along the first direction adjacent to the anti-collision beam 1. That is, the number of energy absorption boxes 2 is two and they are respectively located on both sides of the center line of the anti-collision beam 1 extending along the first direction along the third direction, and the first side panel 22 in each energy absorption box 2 is located on the side of the second side panel 24 adjacent to another energy absorption box 2. At this time, when the anti-collision beam 1 is hit, the first side panel 22 first bears the impact from the anti-collision beam 1. After the first collapse groove 27 and the second collapse groove 28 collapse to deform and shrink the first side panel 22 to the extreme, the first end surface of the first side panel 22 is roughly coplanar with the second end surface of the second side panel 24. At this time, the first side panel 22 and the second side panel 24 jointly bear the impact from the anti-collision beam 1.

[0047] In some embodiments, Figure 4As shown, the third reinforcing plate includes a first sub-plate 5 and a second sub-plate 6 , the first sub-plate 5 is connected to the first reinforcing plate 3 , and the second sub-plate 6 is connected to the second reinforcing plate 4 .

[0048] The first sub-plate 5 is connected to the first reinforcing plate 3 and the second side plate 24, and the second sub-plate 6 is connected to the second reinforcing plate 4 and the second side plate 24. Under the common support of the first reinforcing plate 3 and the second reinforcing plate 4, the first sub-plate 5 and the second sub-plate 6 have a higher supporting strength for the second side plate 24. When the second side plate 24 is impacted by the anti-collision beam 1, it is less likely to be deformed so as to cause tearing at the connection between it and the top plate 21 and the bottom plate 23. The structural integrity and energy absorption stability of the energy absorption box 2 are higher.

[0049] Specifically, the first sub-board 5 and the second sub-board 6 are both in contact with the inner surface of the second side board 24 , and the lower end of the first sub-board 5 is adjacent to the upper end of the second sub-board 6 , thereby increasing the contact area between the first sub-board 5 and the second sub-board 6 and the second side board 24 .

[0050] In addition, the energy absorbing box 2 further includes a third side plate 26 and an intermediate plate 25, the third side plate 26 connects the top plate 21 and the bottom plate 23, the intermediate plate 25 connects the first side plate 22, the second side plate 24 and the third side plate 26, the first sub-plate 5 is located between the intermediate plate 25 and the top plate 21, and the second sub-plate 6 is located between the intermediate plate 25 and the bottom plate 23. The design of the intermediate plate 25 and the third side plate 26 further improves the impact resistance of the energy absorbing box 2, ensures that the energy absorbing box 2 is easy to collapse and deform near the first side plate 22, and has a higher structural integrity.

[0051] In some embodiments, the first reinforcing plate 3 and the first sub-plate 5 are integrally formed, and the second reinforcing plate 4 and the second sub-plate 6 are integrally formed.

[0052] As a result, the connection strength between the first reinforcing plate 3 and the first sub-plate 5 is higher, the connection strength between the second reinforcing plate 4 and the second sub-plate 6 is higher, and the structural stability of the second side plate 24 is stronger, and it can withstand greater impact without deformation. At the same time, this arrangement also reduces the manufacturing cost of the first reinforcing plate 3 to the second sub-plate 6.

[0053] In some embodiments, the first sub-plate 5 is connected to the second side plate 24 via a rivet screw 7 or a threaded member, and the second sub-plate 6 is connected to the second side plate 24 via a rivet screw 7 or a threaded member.

[0054] This ensures the connection strength between each of the first sub-panel 5 and the second sub-panel 6 and the second side panel 24 , while facilitating the assembly and disassembly of the first sub-panel 5 and the second sub-panel 6 on the energy absorption box 2 .

[0055] Specifically, Figure 4 and Figure 5As shown, the first sub-plate 5 is connected to the second side plate 24 via two rivet screws 7 , and the second sub-plate 6 is connected to the second side plate 24 via two rivet screws 7 .

[0056] In some embodiments, the first reinforcing plate 3 is bonded or welded to the first connecting plate 211 , and the second reinforcing plate 4 is bonded or welded to the second connecting plate 231 .

[0057] Therefore, when the energy absorption box 1 is connected to the anti-collision beam 1, the first reinforcement plate 3 is effectively prevented from sliding and dislocating relative to the first connecting plate 211, and the second reinforcement plate 4 is effectively prevented from sliding and dislocating relative to the second connecting plate 231. The assembly efficiency of the anti-collision beam assembly is higher and the assembly reliability is higher.

[0058] It should be noted that a portion of the first reinforcing plate 3 is located in the energy absorption box 2 and is bonded or welded to the portion of the top plate 21 except the first connecting plate 211 , and a portion of the second reinforcing plate 4 is located in the energy absorption box 2 and is bonded or welded to the portion of the bottom plate 23 except the second connecting plate 231 .

[0059] In some embodiments, Figure 3 As shown, the anti-collision beam 1 includes a beam body 11 and an inner sleeve 12, the inner sleeve 12 is connected to the beam body 11 and extends along the second direction, the anti-collision beam assembly includes a bolt 8 and a nut 9, the bolt 8 passes through the first connecting plate 211, the first reinforcing plate 3, the inner sleeve 12, the second reinforcing plate 4 and the second connecting plate 231 in sequence and is threadedly matched with the nut 9.

[0060] That is, the first connecting plate 211, the first reinforcing plate 3, the inner sleeve 12, the second reinforcing plate 4 and the second connecting plate 231 are fixedly connected by a set of bolts 8 and nuts 9 at the same time, so that the assembly efficiency and assembly precision of the anti-collision beam assembly are higher. By adopting the connection mode of bolts 8 and nuts 9, the weakening of mechanical properties caused by welding can be effectively avoided, thereby further ensuring the structural integrity and energy absorption stability of the energy absorption box 2 when it is hit.

[0061] Specifically, Figure 2 As shown, each energy absorption box 2 corresponds to two bolts 8 and two nuts 9 , and the two bolts 8 are arranged at intervals along the extension direction of the anti-collision beam 1 .

[0062] In some embodiments, the first connecting plate 211 is provided with a first mounting hole 2111 and a second mounting hole 2112 for the bolt 8 to pass through, the first mounting hole 2111 and the second mounting hole 2112 are arranged at intervals along the third direction, the third direction, the second direction and the first direction are perpendicular to each other, the first mounting hole 2111 is a round hole, and the second mounting hole 2112 is a long hole extending along the third direction. The second connecting plate 231 is provided with a third mounting hole and a fourth mounting hole for the bolt 8 to pass through, and the projection of the third mounting hole coincides with the projection of the first mounting hole 2111 in the third direction, and the projection of the fourth mounting hole coincides with the projection of the second mounting hole 2112.

[0063] That is, the first mounting hole 2111 and the third mounting hole as round holes can be used as positioning holes to ensure the installation accuracy of the energy absorbing box 2 on the anti-collision beam 1. The second mounting hole 2112 and the fourth mounting hole as long holes can effectively absorb tolerances and reduce the difficulty of installing the energy absorbing box 2 on the anti-collision beam 1.
