Abstract
Description
Technical Field
[0001] This application relates to the field of anti-collision beam technology, and in particular to an anti-collision beam end plate, an anti-collision beam assembly, and a vehicle. Background Technology
[0002] As vehicle safety requirements become increasingly stringent, the energy absorption capacity of anti-collision beams in offset crash tests is no longer sufficient to meet safety standards.
[0003] The existing anti-collision beam assembly includes the anti-collision beam body and the energy absorption box. When the anti-collision beam body is subjected to force, it directly transfers the force to the energy absorption box. The energy absorption effect of the energy absorption box is limited, resulting in a large amount of deformation in the passenger compartment and reducing the safety of the vehicle. Utility Model Content
[0004] The purpose of this application is to solve the aforementioned technical problems by providing a crash beam end plate, a crash beam assembly, and a vehicle, thereby increasing the crumple zone of the energy-absorbing box, improving the energy absorption effect of the crash beam assembly, and ensuring vehicle safety. To achieve the above objective, the technical solution of this application is as follows:
[0005] In a first aspect, this application provides a crash beam end plate for use in an energy-absorbing box. The crash beam end plate includes a first end plate body and a first collapse member. The first end plate body is connected to the end of the energy-absorbing box, and the first collapse member is connected to the outer side of the energy-absorbing box. The first collapse member has a first collapse cavity, and a first partition is provided in the first collapse cavity to divide the first collapse cavity into a plurality of first sub-cavities.
[0006] In one possible implementation, the anti-collision beam end plate also includes a support portion, with the first crumple member and the support portion arranged at a relative interval on the first end plate body, and the support portion connected to the inner side of the energy-absorbing box.
[0007] In one possible implementation, the first crumple member includes a first crumple portion, the outer side of which extends obliquely to the first end plate body relative to the length direction of the vehicle body.
[0008] Secondly, this application provides a crash beam assembly, including the aforementioned crash beam end plate, crash beam body, and energy-absorbing box, with one end of the energy-absorbing box connected to the crash beam end plate and the other end of the energy-absorbing box connected to the crash beam body.
[0009] In one possible implementation, the anti-collision beam assembly further includes a front longitudinal beam end plate. The front longitudinal beam end plate includes a second end plate body and a second crumple member disposed on the second end plate body. One end of the second end plate body is connected to the first end plate body, and the other end of the second end plate body is connected to the front longitudinal beam. The second crumple member is located on the outside of the front longitudinal beam and is disposed corresponding to the first crumple member.
[0010] In one possible implementation, the second crumple member includes a second crumple portion, the outer side of which extends obliquely toward the longitudinal beam relative to the length direction of the vehicle body.
[0011] In one possible implementation, the second collapsible member has a second collapsible cavity, and a second partition is provided in the second collapsible cavity to divide the second collapsible cavity into a plurality of second sub-cavities.
[0012] In one possible implementation, the anti-collision beam assembly further includes a third crumple zone, which is connected to both ends of the anti-collision beam body along the width direction of the vehicle body. The third crumple zone and the first crumple zone are both located on the same side of the energy-absorbing box.
[0013] In one possible implementation, the third collapsible member has a third collapsible cavity, and a third partition is provided in the third collapsible cavity to divide the third collapsible cavity into multiple third sub-cavities.
[0014] Thirdly, this application provides a vehicle including the aforementioned anti-collision beam assembly.
[0015] Compared with the prior art, the beneficial effects of the anti-collision beam end plate, anti-collision beam assembly, and vehicle of this application are mainly reflected in:
[0016] The first crumple component is located on the outer side of the energy-absorbing box. When the energy-absorbing box deforms and collapses, the multiple first sub-cavities in the first crumple component can absorb additional collision energy, increase the amount of collapse of the energy-absorbing box, thereby reducing the transmission of collision force to the passenger compartment, reducing the deformation of the passenger compartment, and enabling the energy-absorbing box to meet safety requirements.

[0030] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0031] Example 1
[0032] This embodiment provides a crash beam end plate applied to the energy-absorbing box 11. Specifically, the crash beam end plate is disposed at the end of the energy-absorbing box 11. Because existing crash beam end plates are flat structures, the energy-absorbing box 11 directly collapses, transmitting the force to the front longitudinal beam 13 through the crash beam end plate. This results in limited energy absorption of the energy-absorbing box 11, failing to meet high safety standards. This embodiment improves the crash beam end plate, which structurally strengthens the energy-absorbing box 11. Through the stress-induced collapse of the crash beam end plate, it provides additional energy absorption for the energy-absorbing box 11. A detailed description follows.
[0033] In the attached diagram, the X-axis is defined as the length direction of the vehicle body, the Y-axis as the width direction, and the Z-axis as the height direction; the side of the component facing the interior space of the vehicle body is defined as the inner side, and the side of the component facing the exterior space of the vehicle body is defined as the outer side.
[0034] like Figures 1-3As shown, the anti-collision beam end plate includes a first end plate body 21, a first crumple member 22, and a support part 23; the first crumple member 22 and the support part 23 are arranged on the first end plate body 21 at a relative interval; the first end plate body 21 is connected to the end of the energy absorption box 11; the support part 23 is connected to the inner side of the energy absorption box 11; and the first crumple member 22 is connected to the outer side of the energy absorption box 11.
[0035] For example, the support part 23 and the first collapsible member 22 are clamped and positioned on both sides of the energy-absorbing box 11. The support part 23 can be a flat plate structure. The support part 23 is connected to the inner side of the energy-absorbing box 11, and the first collapsible member 22 is connected to the outer side of the energy-absorbing box 11. The above connection method can be welding fixation.
[0036] The first crumple member 22 is disposed on the outer side of the energy-absorbing box 11. When the energy-absorbing box 11 deforms and crumples, the first crumple member 22 can absorb additional collision energy, increase the amount of crumpling of the energy-absorbing box 11, thereby reducing the transmission of collision force to the passenger compartment and reducing the deformation of the passenger compartment, so that the energy-absorbing box 11 can meet the safety requirements. The support part 23 is disposed opposite to the first crumple member 22 on the first end plate body 21. When the first crumple member 22 is subjected to force, the support part 23 is located on the inner side of the energy-absorbing box 11, which can provide effective support for the first crumple member 22, improve the structural strength of the anti-collision beam end plate, and ensure the energy absorption effect of the first crumple member 22.
[0037] In one embodiment, the first crumple member 22 includes a first crumple portion 24, the outer side of which extends obliquely to the first end plate body 21 relative to the length direction of the vehicle body.
[0038] For example, such as Figure 3 As shown, the first collapsible member 22 further includes a fixing part 25 and an abutting part 26. The fixing part 25 is arranged opposite to the first collapsible part 24 and is connected to the outer side of the energy-absorbing box 11. The first collapsible part 24 is located outside the fixing part 25. One end of the fixing part 25 is connected to one end of the first collapsible part 24 with the abutting part 26. The abutting part 26 can be arranged perpendicularly to the fixing part 25. The other end of the fixing part 25 and the other end of the first collapsible part 24 are both connected to the first end plate body 21. In other embodiments, the first collapsible member 22 can also be formed by the fixing part 25, the abutting part 26 and the first collapsible part 24 enclosing each other, so that the first collapsible member 22 has a first collapsible inner cavity 31.
[0039] The outer side of the first crumple zone 24 extends at an angle relative to the length of the vehicle body to the first end plate body 21. When the first crumple member 22 is subjected to the impact force of the side pillar, the first crumple zone 24 effectively guides the force flow to the first end plate body 21, so that the first crumple member 22 can deform in the guiding direction of the first crumple zone 24.
[0040] In one embodiment, the first collapsible member 22 has a first collapsible cavity 31, and a first partition 32 is provided in the first collapsible cavity 31 to divide the first collapsible cavity 31 into a plurality of first sub-cavities 33.
[0041] For example, the first crumple zone 22 is provided with a first crumple cavity 31 extending along the height direction of the vehicle body. A plurality of first partitions 32 are provided between the fixing part 25 and the first crumple zone 24. Adjacent first partitions 32 can form a first sub-cavity 33 in the first crumple cavity 31. The first crumple cavity 31 is divided into a plurality of first sub-cavities 33, which effectively improves the collision energy absorption effect of the first crumple zone 22.
[0042] Example 2
[0043] This embodiment provides a crash beam assembly, including the crash beam end plate described above. The crash beam assembly also includes a crash beam body 12 and an energy-absorbing box 11. One end of the energy-absorbing box 11 is connected to the crash beam end plate, and the other end of the energy-absorbing box 11 is connected to the crash beam body 12.
[0044] like Figure 1 , Figure 2 , Figure 4 As shown, the energy-absorbing box 11 is connected to the anti-collision beam body 12 based on the anti-collision beam end plate, which further enhances the energy absorption effect of the anti-collision beam assembly, so that the anti-collision beam end plate can fully play its energy absorption role between the energy-absorbing box 11 and the front longitudinal beam 13.
[0045] In one embodiment, the anti-collision beam assembly further includes a front longitudinal beam end plate, which includes a second end plate body 41 and a second crumple member 42 disposed on the second end plate body 41. One end of the second end plate body 41 is connected to the first end plate body 21, and the other end of the second end plate body 41 is connected to the front longitudinal beam 13. The second crumple member 42 is located on the outside of the front longitudinal beam 13 and is disposed corresponding to the first crumple member 22.
[0046] For example, the second crumple member 42 can be spaced apart from the front longitudinal beam 13 or connected to the outer side of the front longitudinal beam 13. The first crumple member 22 and the second crumple member 42 are arranged correspondingly in the length direction of the vehicle body. This means that when the second crumple member 42 undergoes crumple deformation, the force can be directly transmitted to the second crumple member 42 through the first end plate body 21 and the second end plate body 41. The first crumple member 22 compresses the second crumple member 42, causing the second crumple member 42 to deform and crumple, thereby achieving the effect of fully absorbing energy.
[0047] After the second collapsing member 42 deforms and collapses, it can transmit the force to the front longitudinal beam 13. When the second collapsing member 42 and the front longitudinal beam 13 are spaced apart, the distance between them is reasonably set. After the second collapsing member 42 collapses, it can move and abut against the front longitudinal beam 13, thereby transmitting force to the front longitudinal beam 13.
[0048] In one embodiment, the second crumple member 42 includes a second crumple portion 43, the outer side of which extends obliquely toward the longitudinal beam 13 relative to the length direction of the vehicle body.
[0049] For example, such as Figure 4 As shown, the second crumple member 42 includes two opposing second crumple portions 43. A connecting portion 44, which is away from the second end plate body 41, is connected between the two second crumple portions 43. The inner side of the second crumple portion 43 is spaced apart from the outer side of the front longitudinal beam 13. The inner side of the second crumple portion 43 and the outer side of the front longitudinal beam 13 can also be arranged parallel to each other. The outer side of the second crumple portion 43 is inclined relative to the length direction of the vehicle body. The outer side of the second crumple portion 43 has a tendency to extend toward the front longitudinal beam 13. The second crumple portion 43 can effectively guide the force flow so that the second crumple member 42 can crumple and deform in a set direction. That is, after the second crumple member 42 crumpls, it can effectively abut against the outer side of the front longitudinal beam 13 to realize the force transmission and energy absorption function of the front longitudinal beam 13.
[0050] In one embodiment, the second collapsible member 42 has a second collapsible cavity 51, and a second partition 52 is provided in the second collapsible cavity 51 to divide the second collapsible cavity 51 into a plurality of second sub-cavities 53.
[0051] For example, such as Figure 4 As shown, the second crumple member 42 is provided with a second crumple cavity 51 that extends through the width direction of the vehicle body. A plurality of second partitions 52 are provided between the oppositely arranged second crumple portions 43. The second partitions 52 can divide the second crumple cavity 51 into a plurality of second sub-cavities 53 with arbitrary spatial volume and spatial shape, thereby improving the energy absorption effect of the second crumple member 42.
[0052] In one embodiment, the anti-collision beam body 12 is connected to a third crumple member 61, which is connected to both ends of the anti-collision beam body 12 along the width direction of the vehicle body. The third crumple member 61 and the first crumple member 22 are both located on the same side of the energy absorption box 11.
[0053] For example, such as Figure 5As shown, the anti-collision beam body 12 has third crumple zones 61 at both ends along the width direction of the vehicle body, and an anti-collision beam cavity 14 is provided inside the anti-collision beam body 12. The third crumple zone 61 includes a third crumple portion 62 and a connector 63 connecting the third crumple portion 62. The connector 63 is inserted into the anti-collision beam cavity 14. The third crumple portion 62 is exposed outside the anti-collision beam body 12. The connector 63 can be completely embedded in the inner wall of the anti-collision beam cavity 14, or it can be partially inserted into the inner wall of the anti-collision beam cavity 14. Specifically, the connector 63 has a clamping opening 74, which simultaneously clamps the inner and outer walls of the anti-collision beam cavity 14. The connector 63 and the anti-collision beam body 12 can be fixed by a mounting component, which can be a bolt. The third crumple zone 61 and the anti-collision beam body 12 can be quickly assembled, reducing the difficulty of assembly.
[0054] When the anti-collision beam body 12 is in a small offset collision condition, the anti-collision beam body 12 deforms and the connection between the anti-collision beam body 12 and the energy absorption box 11 deforms and collapses. The third collapse member 61 can move and abut against the abutment part 26 of the first collapse member 22. The third collapse member 61 and the first collapse member 22 abut against each other along the length of the vehicle body, so that the third collapse member 61 and the first collapse member 22 form a continuous force transmission path. The third collapse member 61 and the first collapse member 22 collapse and absorb energy together, giving full play to the energy absorption function of the third collapse member 61.
[0055] In one embodiment, the third collapse member 61 has a third collapse cavity 71, in which a third partition 72 is provided to divide the third collapse cavity 71 into a plurality of third sub-cavities 73.
[0056] For example, such as Figure 5 As shown, a third collapse cavity 71 is formed in the third collapse portion 62. The third collapse cavity 71 can be connected to the outside of the third collapse member 61 through the clamp 74. A plurality of third partition portions 72 are provided in the third collapse cavity 71. The third partition portions 72 can divide the third collapse cavity 71 into a plurality of second sub-cavities 53 with arbitrary spatial volume and spatial shape, thereby improving the energy absorption effect of the third collapse member 61.
