Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body structural component assembly and a vehicle. Background Technology

[0002] In related technologies, when a vehicle body is subjected to a strong impact, its energy absorption effect is somewhat insufficient, and the vehicle body is prone to significant deformation, resulting in substantial compression of the passenger compartment and causing injury to occupants or cargo. Therefore, related technologies suffer from insufficient energy absorption and significant deformation upon impact. Summary of the Invention

[0003] This application provides a vehicle body structural component and a vehicle that can improve the energy absorption effect of the vehicle body and reduce the degree of deformation of the vehicle body when it is subjected to an impact.

[0004] In a first aspect, this application provides a vehicle body structural component assembly, which includes a first structural component, a second structural component, and an energy-absorbing mechanism. The second structural component is arranged along a first direction and fixedly connected to the first structural component. The energy-absorbing mechanism includes a first mounting component and a tensioning component. The first mounting component is disposed on the first structural component and extends from the first structural component toward the second structural component; the first mounting component and the second structural component are separate structures. The tensioning component is connected to the end of the first mounting component and extends from the end of the first mounting component toward the first structural component; the end of the tensioning component is connected to the second structural component, so that during the movement of the second structural component toward the first structural component, the tensioning component can undergo tensile deformation in the first direction.

[0005] The vehicle body structural component assembly provided in this application includes an energy-absorbing mechanism between the first and second structural components. This mechanism can distribute the impact force in a first direction received by one of the first and second structural components, redirecting the impact force to the other, thus reducing the deformation of the first structural component. The energy-absorbing mechanism converts the impact force into tensile force on a tension member. When the tension member is subjected to tensile force, it undergoes tensile deformation, thereby absorbing impact energy. Utilizing the tensile deformation of the tension member to absorb impact energy results in a significant energy absorption effect. Therefore, this application can improve the energy absorption effect of the vehicle body and reduce the degree of deformation of the vehicle body upon impact.

[0006] For example, the tension member is made of a stretchable material, and the tension member stretches and deforms as the second structural member moves toward the first structural member.

[0007] For example, the first structural member is a column, which is used to fix to the sill beam of the vehicle body and extends upward along the height direction of the vehicle body; the second structural member is a longitudinal beam, which extends along the length direction of the vehicle body; the first direction is the length direction, and the column and the first end of the longitudinal beam are fixedly connected in the length direction.

[0008] For example, the column is column A, the longitudinal beam is the upper longitudinal beam, and the rear end of the upper longitudinal beam is the first end of the longitudinal beam along the length direction.

[0009] For example, the inner cavity of the column is a first cavity with a first opening. In the length direction, the first opening is formed on the end face of the column near the longitudinal beam. The inner cavity of the longitudinal beam is a second cavity with a second opening. The second opening is formed on the end face of the first end. The second opening is disposed in conjunction with the first opening. The first mounting member is disposed on the inner wall of the first cavity and extends into the second cavity through the second opening and the first opening to connect with the tensioning member.

[0010] For example, the portion where the column is connected to the first mounting member is the first part, and the portion where the longitudinal beam is connected to the tension member is the second part, with the second part and the first part having a gap in the width direction of the vehicle body.

[0011] For example, along the width direction, the first portion is disposed near the end of the vehicle body, and the second portion is disposed near the middle of the vehicle body.

[0012] For example, the longitudinal beam includes an inner plate and an outer plate, the inner plate and the outer plate being arranged opposite each other in the width direction; the column includes an inner plate and an outer plate, the inner plate and the outer plate being arranged opposite each other in the width direction; the inner plate of the longitudinal beam and the inner plate of the column are spliced ​​together, and the outer plate of the longitudinal beam and the outer plate of the column are spliced ​​together; a second part is formed on the inner plate of the longitudinal beam, and a first part is formed on the outer plate of the column.

[0013] For example, the portion where the longitudinal beam is connected to the tension member is the second portion, and the portion where the column is connected to the first mounting member is the first portion, with the second portion and the first portion having a gap in the height direction.

[0014] For example, the energy absorption mechanism further includes a second mounting member, and the end of the tension member is connected to the second structural member through the second mounting member; the portion of the second structural member connected to the second mounting member is the second part, the portion of the first structural member connected to the first mounting member is the first part, and the extension direction of the tension member is parallel to the line connecting the second part and the first part.

[0015] Secondly, this application provides a vehicle that includes the body structure component provided in the first aspect of this application.

[0016] The vehicle provided in this application includes the body structure components provided in the first aspect of this application, which can achieve the same effect, namely, improve the energy absorption effect of the body and reduce the degree of longitudinal beam intrusion into the vehicle compartment.

The terminology used in the embodiments of this application is for descriptive purposes only and is not intended to limit the scope of the embodiments of this application.

[0033] This application provides a vehicle, which can be of various types. In some embodiments of this application, it can be a sedan, off-road vehicle, sport utility vehicle (SUV), bus, truck, pickup truck, or RV, etc.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The vehicle provided in this application embodiment includes a vehicle body, which includes a vehicle body structural component assembly. The vehicle body structural component assembly includes a first structural component 2, a second structural component 1, and an energy-absorbing mechanism 3. The second structural component 1 and the first structural component 2 are arranged along a first direction and fixedly connected to the first structural component 2. The energy-absorbing mechanism 3 includes a first mounting component 32 and a tensioning component 33. The first mounting component 32 is disposed on the first structural component 2 and extends from the first structural component 2 towards the second structural component 1. The first mounting component 32 and the second structural component 1 are separate structures. The tensioning component 33 is connected to the end of the first mounting component 32 and extends from the end of the first mounting component 32 towards the first structural component 2. The end of the tensioning component 332 is connected to the second structural component 1, so that during the movement of the second structural component 1 towards the first structural component 2, the tensioning component 33 can undergo tensile deformation in the first direction. In this structural configuration, an energy-absorbing mechanism 3 is provided between the first structural member 2 and the second structural member 1. The energy-absorbing mechanism 3 can share the impact force in the first direction received by one of the first structural member 2 and the second structural member 1, and redirect the impact force to the other, thus reducing the deformation of the first structural member 2. The energy-absorbing mechanism 3 can convert the impact force into tensile force on the tension member 33. When the tension member 33 is subjected to tensile force, it undergoes tensile deformation, thereby absorbing impact energy. Utilizing the tensile deformation of the tension member 33 to absorb impact energy results in a significant energy absorption effect. Therefore, this application can improve the energy absorption effect of the vehicle body and reduce the degree of deformation of the vehicle body when it is impacted.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 It is understood that, in the embodiments of this application, for the impact force in the first direction received by one of the first structural member 2 and the second structural member 1, the impact force is directed from one of the first structural member 2 and the second structural member 1 to the other, so that the first structural member 2 and the second structural member 1 have a tendency to move closer to each other.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 It should be explained that, in this embodiment, the end of the first mounting member 32 refers to the end of the first mounting member 32 that is away from the first structural member 2. The end 332 of the tension member refers to the end of the tension member 33 that is away from the end of the first mounting member 32, and the beginning end 331 of the tension member refers to the end of the tension member 33 that is connected to the end of the first mounting member 32.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 It is understood that, in this embodiment of the application, the direction in which the first end 331 of the tension member points to the end of the tension member 33 is opposite to the direction in which the first structural member 2 points to the second structural member 1. During the movement of the second structural member 1 toward the first structural member 2, the second structural member 1 drives the end 332 of the tension member to move away from the first end of the tension member 33, causing the tension member 33 to be deformed under tension.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first mounting member 32 can be fixedly connected to the first structural member 2. In some embodiments of this application, the tension member 33 can be fixedly connected to the end of the first mounting member 32. In some embodiments of this application, the end 332 of the tension member can be fixedly connected to the second structural member 1. This structural form helps to improve the stability of the tension member 33 installation, thereby ensuring that the tension member 33 has a better energy absorption effect.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the tension member 33 may be made of a malleable material. During the movement of the second structural member 1 towards the first structural member 2, the tension member 33 extends and deforms. Thus, utilizing the malleable properties of the material for energy absorption results in a significant energy absorption effect. In some embodiments of this application, the malleable material may be a high-strength alloy material with high elongation after fracture. In some embodiments of this application, the tension member 33 is made of high-manganese austenitic twin-induced plasticity steel. In some embodiments of this application, the tension member 33 is made of porous metal, such as honeycomb aluminum. Of course, in some embodiments of this application, the tension member 33 may not be made of a malleable material; for example, the tension member 33 may be a tension spring, which is stretched during the movement of the second structural member 1 towards the first structural member 2.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3It is understandable that the energy absorption is achieved by utilizing the compressibility of the parts, i.e., there is a support member between the first structural member 2 and the second structural member 1. The support member is under pressure. As the first structural member 2 and the second structural member 1 approach each other, the support member is deformed under pressure to absorb the impact force. The energy absorption effect is worse than that of using the stretching deformation of the stretching member 33 to absorb energy.

[0041] Specifically, during the tensile deformation process of the tension member 33, the deformation process includes an elastic deformation stage, a yielding stage, a strengthening stage, and a necking stage. When the stress reaches the yield strength, the tension member 33 will undergo yield deformation. However, if the tension continues, the tension member 33 must also go through the strengthening stage and the necking stage before it will fracture and fail. During the strengthening stage and the necking stage, the tension member 33 can withstand a larger force, the degree of deformation is also larger, more work is done by external forces, and the energy absorption effect is better. For the support member that absorbs energy under pressure, the deformation process includes an elastic deformation stage, a yielding stage, and a fracture stage. After the yielding stage, the stiffness of the support member increases dramatically, the deformation capacity is poor, and the energy absorption effect also becomes poor.

[0042] During the compression process, the support member undergoes an elastic phase, and it becomes difficult to deform further with a small amount of compression. In contrast, during the tension process, the tension member 33 undergoes an elastic phase, and it will only break with a larger amount of tension. When the stiffness and size of the support member and the tension member 33 are roughly the same, the deformation capacity of the tension member 33 during the tension process is much greater than that of the support member during the compression process. This makes the energy absorption effect of the tension deformation of the tension member 33 stronger than that of the energy absorption effect of the compression deformation of the support member.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the first direction can be implemented in various ways. For example, the first direction can be the length direction a of the vehicle body, so that the tension member 33 can absorb the impact force in the length direction a of the vehicle body; the first direction can be the width direction c of the vehicle body, so that the tension member 33 can absorb the impact force in the width direction c of the vehicle body. The first direction can be the height direction b of the vehicle body, so that the tension member 33 can absorb the impact force in the height direction b of the vehicle body. For the impact force in the height direction b, for example, it can be the impact force of the ground on the bottom of the vehicle, or the impact force of a falling object on the roof of the vehicle, etc.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3In this application, the first structural member 2 and the second structural member 1 can be implemented in various ways. For example, in some embodiments of this application, the first structural member 2 and the second structural member 1 can be a pillar and a sill beam structure, respectively, where the pillar can refer to an A-pillar, B-pillar, C-pillar, or D-pillar, etc.; in some embodiments of this application, the first structural member 2 and the second structural member 1 can be a pillar and a top beam structure, respectively, with the top beam structure extending along the length direction 'a' of the vehicle to form a door frame. In some embodiments of this application, the first structural member 2 and the second structural member 1 can be two sheet metal parts arranged opposite each other, such as an outer door panel and an inner door panel. In some embodiments of this application, the first structural member 2 and the second structural member 1 can be two segments arranged in their own extension direction, such as a beam structure, a pillar, or a plate structure. For example, the beam structure can be a sill beam or a crash beam, etc.

[0045] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first structural member 2 and the second structural member 1 are arranged adjacent to each other. This structural configuration, with the first structural member 2 and the second structural member 1 being relatively close, facilitates the installation of the energy absorption device.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first structural member 2 is a column, which is fixed to the sill beam of the vehicle body and extends upward from the sill beam along the height direction b of the vehicle body; the second structural member 1 is a longitudinal beam, which extends along the length direction a of the vehicle body; the first direction is the length direction a, and the column and the first end of the longitudinal beam in the length direction a are fixedly connected. It should be explained that in the embodiments of this application, the longitudinal beam is located at the end of the length direction a of the vehicle body, and the column is located in the middle of the length direction a of the vehicle body. The longitudinal beam can be located at the front end of the vehicle body or at the rear end of the vehicle body. Exemplarily, in some embodiments of this application, the longitudinal beam is located at the front end of the vehicle body, and the column is located on the side of the longitudinal beam near the rear end of the vehicle body. During the process of the front end of the vehicle body being impacted towards the rear end of the vehicle body, the impact force is transmitted to the column through the longitudinal beam along the length direction a of the vehicle body.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3In this embodiment, the longitudinal beam is located at the end of the vehicle body along the length direction a, making it susceptible to impact. Upon impact, the impact force is transmitted to the pillar along the length direction a of the vehicle body. The pillar is mounted on the sill beam, ensuring a stable installation and preventing deformation. This provides sufficient support for the energy-absorbing mechanism 3, allowing it to effectively absorb energy. Furthermore, the close proximity of the longitudinal beam and the pillar facilitates the installation of the energy-absorbing mechanism 3. Additionally, the longitudinal beam's large extension along the length direction a allows for significant deformation during impact, resulting in a large range of motion at the connection between the longitudinal beam and the tension member 33. This allows for full utilization of the tension member 33's tensile deformation capacity, achieving a better energy absorption effect.

[0048] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the longitudinal beam can refer to the lower longitudinal beam used to install the anti-collision beam. In this case, the column is column A, and along the length direction a, the rear end of the lower longitudinal beam is the first end 11 of the longitudinal beam, and the front end of the lower longitudinal beam is the second end 12 of the longitudinal beam. The longitudinal beam can also refer to the upper longitudinal beam, i.e., the shotgun. In this case, the column is column A, and along the length direction a, the rear end of the upper longitudinal beam is the first end 11 of the longitudinal beam. The longitudinal beam can also refer to the rear longitudinal beam. In this case, the column is column C or column D, and along the length direction a, the front end of the upper longitudinal beam is the first end 11 of the longitudinal beam.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 It is understandable that the strength of the upper longitudinal beam is relatively small. Setting up an energy-absorbing mechanism 3 between the upper longitudinal beam and the A-pillar can significantly reduce the deformation of the upper longitudinal beam after an impact.

[0050] Please refer to Figure 1 and Figure 4 The inner cavity of the pillar is a first cavity 21, which has a first opening 211. Along the length direction a, the first opening 211 is formed on the end face of the pillar near the longitudinal beam. In some embodiments of this application, the inner cavity of the longitudinal beam is a second cavity 13, which has a second opening 131 formed on the end face of the first end. The second opening 131 is abutted against the first opening 211. A first mounting member 32 is disposed on the inner wall of the first cavity 21 and extends into the second cavity 13 through the second opening 131 and the first opening 211 to connect with the tension member 33. This structural form, by placing the first end of the first mounting member 32 within the second inner cavity, improves the utilization rate of the second inner cavity and helps to enhance the compactness of the vehicle body.

[0051] Please refer to Figure 1 and Figure 4It should be explained that the inner cavity of the longitudinal beam and the inner cavity of the column have the same meaning as commonly understood by those skilled in the art. Taking the inner cavity of the longitudinal beam as an example, the inner cavity of the longitudinal beam is the cavity formed by the inner and outer plates that make up the longitudinal beam.

[0052] Please refer to Figure 1 and Figure 4 It is understood that in this embodiment, the first mounting member 32 extends into the second cavity 13 through the second opening 131 and the first opening 211 to connect with the tension member 33, indicating that the first end 331 of the tension member is located within the second cavity 13. In some embodiments of this application, the tension member 33 is located within the second cavity 13, and the end 332 of the tension member is fixedly connected to the inner wall of the second cavity 13. This improves the utilization rate of the second cavity 13 and helps to enhance the compactness of the vehicle body.

[0053] Please refer to Figure 1 and Figure 4 It is understood that in the embodiments of this application, the second opening 131 is connected to the first opening 211, so that the second cavity 13 and the first cavity 21 are connected to form a cavity assembly. In some embodiments of this application, the energy absorption mechanism 3 is disposed within the cavity assembly. This structural form is beneficial to improving the compactness of the vehicle body.

[0054] Please refer to Figure 1 and Figure 4 In some embodiments of this application, the portion connecting the column to the first mounting member 32 is the first portion 22, and the portion connecting the longitudinal beam to the tension member 33 is the second portion 14. The second portion 14 and the first portion 22 are spaced apart in the width direction c of the vehicle body. This structural form is advantageous because the energy-absorbing mechanism 3 can convert part of the impact force in the length direction a into a force in the width direction c, thereby helping to reduce the deformation of the vehicle body in the length direction a. Moreover, it also helps to make the support range of the energy-absorbing mechanism 3 larger, resulting in a better energy absorption effect.

[0055] Please refer to Figure 1 and Figure 4 In some embodiments of this application, along the width direction c, the first portion 22 is disposed near the end of the vehicle body, and the second portion 14 is disposed near the middle of the vehicle body. This facilitates the energy absorption mechanism 3 in directing the impact force located in the middle of the vehicle body in the width direction c to the end of the vehicle body in the width direction c, thereby reducing the deformation of the middle of the vehicle body in the width direction c and reducing the compression of the vehicle compartment when the vehicle body is impacted.

[0056] Please refer to Figure 1 and Figure 4In some embodiments of this application, the longitudinal beam includes an inner longitudinal beam plate 15 and an outer longitudinal beam plate 16, with the inner longitudinal beam plate 15 and the outer longitudinal beam plate 16 arranged opposite each other along the width direction c; the column includes an inner column plate 23 and an outer column plate 24, with the inner column plate 23 and the outer column plate 24 arranged opposite each other along the width direction c; the inner longitudinal beam plate 15 and the inner column plate 23 are spliced ​​together, and the outer longitudinal beam plate 16 and the outer column plate 24 are spliced ​​together; the second part 14 is formed on the inner longitudinal beam plate 15, and the first part 22 is formed on the outer column plate 24. With this structural form, the installation stability of the energy absorption mechanism 3 is relatively high, and the second part 14 and the first part 22 have a large distance in the width direction c of the vehicle body, which is beneficial to improving the buffering effect of the energy absorption mechanism 3.

[0057] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the portion connecting the column to the first mounting member 32 is the first portion 22, and the portion connecting the longitudinal beam to the tension member 33 is the second portion 14. The second portion 14 and the first portion 22 are spaced apart in the height direction b. This structural form is beneficial for the energy-absorbing mechanism 3 to convert part of the impact force in the length direction a into a force in the height direction b, thereby helping to reduce the deformation of the vehicle body in the length direction a. Moreover, it also helps to make the support range of the energy-absorbing mechanism 3 larger, resulting in a better energy absorption effect. In some embodiments of this application, the longitudinal beam is an upper longitudinal beam, and the second portion 14 is higher than the first portion 22 in the height direction b.

[0058] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the angle between the line connecting the second part 14 and the first part 22 and the horizontal plane e is a first angle d, and the size of the first angle d is 45 degrees.

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the energy-absorbing mechanism 3 further includes a second mounting member 31, and the end 332 of the tension member is connected to the second structural member 1 through the second mounting member 31; the part where the second structural member 1 is connected to the second mounting member 31 is the second part 14, and the part where the first structural member 2 is connected to the first mounting member 32 is the first part 22. The extension direction of the tension member 33 is parallel to the line connecting the second part 14 and the first part 22. This structural form is advantageous because, during the process of the second part 14 and the first part 22 approaching each other, the deformation of the tension member 33 is smaller in the direction perpendicular to its own extension direction, while the deformation in its own extension direction is larger. This helps to make the tensile deformation process of the tension member 33 more stable, which is beneficial to fully utilize the tensile deformation capacity of the tension member 33 and improve the energy absorption effect.

[0060] Please refer to Figure 1 , Figure 2 and Figure 3 Based on the fact that the extension direction of the tension member 33 is parallel to the line connecting the second part 14 and the first part 22, in some embodiments of this application, the second mounting member 31 is a rod, and the first mounting member 32 is a cylinder. The axial direction of the rod is the same as that of the cylinder. The first end of the rod is fixedly connected to the longitudinal beam. The rod extends from the longitudinal beam toward the column to extend into the cylinder along the axial direction. The end of the cylinder away from the first end of the rod is fixedly connected to the column. The tension member 33 extends into the cylinder along the axial direction, with one end connected to the second end of the rod and the other end connected to the end of the cylinder near the first end of the rod. With this structural form, the rod is installed inside the cylinder, and the tension member 33 also extends into the cylinder, which helps to achieve better installation stability among the first mounting member 32, the second mounting member 31, and the tension member 33. In some embodiments of this application, the cylinder is made of a corrugated material, so that the cylinder can be compressed as the second part 14 and the first part 22 approach each other, thereby further improving the energy absorption effect of the energy absorption mechanism 3.

[0061] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first mounting member 32 is provided with a first rivet hole 321, so that it can be fixed to the column by a second rivet. In some embodiments of this application, the second mounting member 31 is provided with a second rivet hole 311, so that it can be fixed to the longitudinal beam by a first rivet. This structural form is beneficial to improving the stability of the energy absorption mechanism 3 installation.

[0062] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, there are multiple tension members 33, which are arranged circumferentially along the rod. This structural form is beneficial to improving the energy absorption effect of the energy absorption mechanism 3, and also to reducing the degree of eccentric movement of the rod relative to the cylinder in the axial direction.

[0063] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first end 331 of the tension member passes through and protrudes from the first mounting member 32. The first end 331 of the tension member has an external thread so that the portion of the first end 331 protruding from the first mounting member 32 can be threadedly connected to a nut. The nut abuts against the first mounting member 32 axially to restrict the movement of the first end 331 of the tension member towards the column. With this structure, the installation of the tension member 33 is more stable.

[0064] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the end 332 of the tension member is formed with a flange that extends outward in the radial direction of the tension member 33. The end face of one end of the flange along the extension direction of the tension member 33 abuts against the second mounting member 31 to restrict the movement of the end 332 of the tension member toward the beginning end 331 of the tension member.

[0065] Please refer to Figure 1 and Figure 5 In some embodiments of this application, the second cavity 13 includes a mounting cavity and a first filling cavity; the second mounting member 31 is fixedly connected to the inner wall of the mounting cavity to be fixedly connected to the inner wall of the second cavity 13, and a second opening 131 is formed on the mounting cavity; the first filling cavity is located on the side of the mounting cavity away from the first cavity 21, and the first filling cavity is filled with a first foaming material 4. With this structural form, the first foaming material 4 can effectively absorb impact force, which helps to prevent the longitudinal beam from being crushed.

[0066] Please refer to Figure 1 and Figure 5 In some embodiments of this application, the longitudinal beam includes a first longitudinal beam segment 191 and a second longitudinal beam segment 192. The first longitudinal beam segment 191 and the second longitudinal beam segment are welded together. The first longitudinal beam segment 191 and the second longitudinal beam segment 192 are butted together along the length direction a. The end of the second longitudinal beam segment 192 away from the first longitudinal beam segment 191 is connected to a column. The first foaming material 4 and the energy-absorbing mechanism 3 are both disposed within the second longitudinal beam segment 192. With this structural form, the first foaming material 4 and the energy-absorbing mechanism 3 can be installed within the second longitudinal beam segment 192 firstly, and then the first longitudinal beam segment 191 and the second longitudinal beam segment 192 can be welded together, which improves the ease of assembly. In some embodiments of this application, the inner cavity of the first longitudinal beam segment 191 and the inner cavity of the second longitudinal beam segment 192 are not connected. The first foaming material 4 is disposed at the end of the second longitudinal beam segment 192 near the first longitudinal beam segment 191 and is supported on the end face of the second longitudinal beam segment 192 near the end of the first longitudinal beam segment 191. With this structural form, the first foam material 4 and the longitudinal beam are fully supported in the length direction a, which is conducive to improving the energy absorption effect of the first foam material 4.

[0067] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the longitudinal beam is fixedly connected to the upper end of the column; the inner cavity of the column includes a second filling cavity located above the longitudinal beam, and the second filling cavity is filled with a second foaming material 5. With this structural form, the first foaming material 4 can effectively absorb the impact force transmitted by the longitudinal beam, which helps to prevent the column from being crushed.

[0068] Please refer to Figure 1and Figure 7 In some embodiments of this application, the longitudinal beam further includes a first wall 17 and a second wall 18, which are arranged opposite each other along the height direction b to form a second cavity 13. The distance between the first wall 17 and the second wall 18 gradually increases along the longitudinal beam towards the column. This structural configuration results in a larger volume of the second cavity 13 at the first end 11 of the longitudinal beam, which helps to increase the contact area between the first end 11 of the longitudinal beam and the column, thus improving the installation stability of the longitudinal beam.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
