Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a vehicle body structure and a vehicle equipped with the vehicle body structure. Background Technology

[0002] Gasoline-powered vehicles require fuel lines running from the front compartment to the rear, such as the fuel line connecting the fuel tank and the engine in the front compartment, and the brake lines from the front compartment to the rear wheels. With the increasing functionality and number of components in modern vehicles, the front compartment space is becoming increasingly cramped, reducing the adjustability of fuel line routing. Typically, at least some sections will be located between the front bulkhead assembly (usually located below the windshield, between the front compartment and the passenger compartment) and components such as the engine assembly. Furthermore, the distance between the engine assembly and the front bulkhead assembly is relatively small in current models. In a frontal collision, components in the front compartment, such as the engine assembly, will shift rearward and are more likely to collide with the front bulkhead assembly. Fuel lines in the front compartment are also susceptible to damage from the sharp points of these rearward-shifting components, leading to fuel leaks and safety risks. Utility Model Content

[0003] In view of this, this application aims to provide a vehicle body structure that can reduce the impact of the powertrain on the front crossbeam assembly, enhance the protection of oil pipes, reduce the safety risk of oil leakage caused by oil pipe damage due to collision, and improve the crashworthiness and safety of the whole vehicle.

[0004] This application provides a vehicle body structure, including a front bulkhead crossbeam assembly and an oil pipe disposed behind the powertrain in the longitudinal direction of the vehicle body, wherein a portion of the oil pipe is located between the crossbeam body of the front bulkhead crossbeam assembly and the powertrain, and further includes:

[0005] A protective cover is disposed on the front side of the front bulkhead beam assembly, connected to the front bulkhead beam assembly, and used to cover the local section of the oil pipe;

[0006] An energy-absorbing structure is connected to the front beam assembly and is located at least partially on the front side of the front beam assembly.

[0007] In one possible implementation, the front bulkhead beam assembly includes a beam body and a lower front bulkhead plate located below the beam body;

[0008] The protective cover includes a section located on the front side of the crossbeam body and a section located on the front side of the lower front panel and opposite to the exhaust pipe of the powertrain.

[0009] In one possible implementation, the energy-absorbing structure includes an energy-absorbing box located on the front side of the lower front panel and connected to the lower front panel, and the lower end of the protective cover is at least partially located above the energy-absorbing box and connected to the top surface of the energy-absorbing box.

[0010] In one possible implementation, the energy-absorbing box and the central channel on the rear side of the front bulkhead beam assembly are aligned front to back, and the central channel is connected to the rear side of the lower front bulkhead plate.

[0011] In one possible implementation, the protective cover includes a cover plate, and a first side plate and a second side plate arranged on both sides of the cover plate, wherein the first side plate, the cover plate and the second side plate are connected in sequence to form a protective cavity covering the oil pipe.

[0012] In one possible implementation, the upper end of the local section of the oil pipe is connected to the crossbeam body and located above the energy-absorbing structure, and the lower end is connected to the first side of the energy-absorbing structure near the first side plate.

[0013] The cover plate includes a main section, a first part of which is located above the energy-absorbing structure in the vehicle width direction, and a second part of which is connected to an extension section extending to the first side of the energy-absorbing structure, the extension section having an angle with the main section.

[0014] In one possible implementation, the extended section is connected to the first side plate;

[0015] And / or, a weight-reduction hole is provided on the first side plate;

[0016] And / or, the dimension of the lower end of the cover plate in the vehicle width direction is smaller than the dimension of the upper end of the cover plate in the vehicle width direction.

[0017] In one possible implementation, the protective shield includes:

[0018] The first lug is located on one side of the first side plate and is connected to the crossbeam body of the front crossbeam assembly.

[0019] The second lug is located on one side of the second side plate and is connected to the crossbeam body of the front crossbeam assembly.

[0020] The third lug is located at the lower end of the cover plate and is connected to the top surface of the energy-absorbing structure.

[0026] The vehicle body structure provided in this application includes an energy-absorbing structure and a protective cover for the oil pipes on the front side of the front bulkhead crossbeam assembly. When a frontal collision occurs, as the powertrain moves towards the front bulkhead crossbeam assembly, it will first collide with the energy-absorbing structure. This structure effectively absorbs the collision energy, mitigating the impact on the powertrain and reducing the degree of impact between the powertrain and the front bulkhead crossbeam assembly and the oil pipes. Furthermore, the protective cover over the oil pipes also absorbs the impact of the powertrain collision, disperses the impact force, and effectively resists the puncture of the oil pipes by the sharp points of rearward-moving components, thus effectively protecting the oil pipes.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] It should be noted in advance that in vehicles, the length direction of the vehicle body is usually referred to as the front-rear direction, with the front of the vehicle being the front and the rear being the rear. In this application, the side of any component facing the front of the vehicle is referred to as the front side or front, and the side of the component facing the rear of the vehicle is referred to as the rear side or rear.

[0048] Please refer to the attached document. Figures 1-12 This application provides a vehicle body structure including a front bulkhead crossbeam assembly 4 and oil pipes 7. The front bulkhead crossbeam assembly 4 is located behind the powertrain 6 in the length direction of the vehicle body (X direction shown in the figures), typically below the windshield, and between the front compartment and the passenger compartment. Figure 2 As shown, the front beam assembly 4 includes a beam body 40, a front panel 41 located above the beam body 40, and a lower front panel 42 located below the beam body 40. Figure 1 The diagram illustrates the connection between the front bulkhead crossbeam assembly 4 and other components on the vehicle body in some embodiments. The rear side of the front bulkhead crossbeam assembly 4 is connected to the vehicle floor, and both ends in the width direction of the vehicle body (Y direction shown in the attached diagram) are connected to the first longitudinal beam 21 and the second longitudinal beam 22. Both the first longitudinal beam 21 and the second longitudinal beam 22 are connected to the front bumper beam 1. The front bumper beam 1, the first longitudinal beam 21, the front bulkhead crossbeam assembly 4, and the second longitudinal beam 22 are connected end to end to form a U-shaped front cabin frame. The central passage 5 is connected to the front bulkhead crossbeam assembly 4 and is located at the rear of the front bulkhead crossbeam assembly 4.

[0049] The fuel lines 7 typically include a fuel line 71 connecting the engine and the fuel tank, and brake lines 72 leading from the hydraulic tank to each wheel. The fuel lines 7 are typically laid from the front of the front bulkhead crossbeam assembly 4 onto the front bulkhead crossbeam assembly 4, and then extend rearward along the vehicle floor, such as... Figure 4As shown in the diagram, a section of the oil pipe 7 is located between the crossbeam body 40 of the front bulkhead crossbeam assembly 4 and the powertrain 6 (in the front bulkhead crossbeam assembly 4, the crossbeam body 40 is the area closest to the powertrain 6, and the rearward movement of the powertrain 6 results in a collision with the front beam surface 401 of the crossbeam body 40). For ease of description, this section is referred to as the impact-prone section. In this application, the vehicle body structure is also provided with a protective shield 8 and an energy-absorbing structure. The energy-absorbing structure is connected to the front bulkhead crossbeam assembly 4 and is located at least partially on the front side of the front bulkhead crossbeam assembly 4. This is so that when the front of the vehicle is impacted and the powertrain 6 moves backward, the energy-absorbing structure will first contact the powertrain 6 and absorb the crumple zone, reducing the impact degree of the powertrain 6 on the front bulkhead crossbeam assembly 4 or preventing the powertrain 6 from impacting the front bulkhead crossbeam assembly 4. The protective shield 8 is also located on the front side of the front bulkhead crossbeam assembly 4 and is connected to the front bulkhead crossbeam assembly 4. The section of the oil pipe 7 located between the crossbeam body 40 and the powertrain 6 is connected and used to cover the impact-prone section. When the powertrain 6 moves backward, the impact force is reduced by the energy absorption of the energy-absorbing structure. Even if the powertrain 6 hits the protective cover 8, the impact will be reduced. In addition, the protective cover 8 will continue to offset the impact force by covering the oil pipe 7 and will also block the sharp points of the components from puncturing the oil pipe 7. This can significantly reduce the collision damage to the oil pipe 7 and effectively protect the impact-prone section of the oil pipe 7.

[0050] Specifically, the vehicle body structure provided in this application features an energy-absorbing structure and a protective cover 8 for the oil pipe 7 on the front side of the front crossbeam assembly 4. When a frontal collision occurs, as the powertrain 6 moves towards the front crossbeam assembly 4, it will first collide with the energy-absorbing structure. The energy-absorbing structure effectively absorbs the collision energy, mitigates the impact of the powertrain 6, and effectively reduces the impact of the powertrain 6 on the front crossbeam assembly 4 and the oil pipe 7. Furthermore, the protective cover 8, which covers the oil pipe 7, also absorbs the impact of the powertrain 6, disperses the impact force, and effectively resists the puncture of the oil pipe 7 by the sharp point of the rearward-moving component, effectively protecting the oil pipe 7. Therefore, the vehicle body structure provided in this application can reduce the impact of the powertrain 6 on the front crossbeam assembly 4, enhance the protection of the oil pipe 7, reduce the safety risk of oil leakage due to potential damage to the oil pipe 7 during a collision, and improve the overall crashworthiness and safety of the vehicle.

[0051] Meanwhile, because the energy-absorbing structure can directly absorb and buffer the powertrain 6 and other devices in the front compartment during a frontal collision, it reduces the amount of intrusion of the powertrain 6 and other devices into the passenger compartment, thus avoiding the problem of excessive intrusion of the front bulkhead beam assembly 4 into the front compartment and poor overall vehicle crashworthiness. Furthermore, in the body structure provided in this application, because an energy-absorbing structure is added to the front side of the front bulkhead beam assembly 4, it can specifically absorb and buffer the powertrain 6 of different sizes, thereby facilitating the standardization of the powertrain 6 mounting points. In addition, the energy-absorbing structure can also reduce the strength requirements of the front bulkhead beam assembly 4, which helps to reduce the design complexity of the front bulkhead beam assembly 4.

[0052] Please see Figures 2 to 6 The front bulkhead crossbeam assembly 4 includes a front bulkhead panel 41, a crossbeam body 40, and a front bulkhead lower panel 42 connected sequentially from top to bottom. The upper end of the front bulkhead lower panel 42 is connected to the crossbeam body 40, and the lower end of the front bulkhead lower panel 42 extends rearward and downward relative to its upper end for connection with the vehicle floor. The central tunnel 5 is connected to the front bulkhead lower panel 42 and is located on the rear side of the front bulkhead lower panel 42. Specifically, the energy-absorbing structure is connected to the front bulkhead lower panel 42, located on the front side of the front bulkhead lower panel 42, and extends toward the powertrain 6 or the front bumper beam 1.

[0053] Specifically, the energy-absorbing structure can be the energy-absorbing box 3, or any other structure with energy-absorbing effect. For ease of understanding, this article will use the energy-absorbing box 3 as an example for specific explanation.

[0054] The energy-absorbing box 3 is located behind the powertrain 6 and is connected to the front side of the lower front panel 42. See also the following embodiments: Figure 1 and Figure 12 The energy-absorbing box 3 is located on the longitudinal extension line of the central channel 5, that is, the energy-absorbing box 3 and the central channel 5 are located on the front and rear sides of the lower front panel 42, respectively, and the projections of the energy-absorbing box 3 and the central channel 5 in the vehicle's longitudinal direction at least partially overlap. In this way, when a collision occurs at the front of the vehicle, the energy-absorbing box 3 can form a force transmission path to the central channel 5, which can better absorb energy and more effectively reduce the damage to the front crossbeam assembly 4 and the passenger compartment.

[0055] Along the height of the vehicle body, it is also attached Figure 1 As shown in the Z-direction, the protective cover 8 includes a section located on the front side of the crossbeam body 40 and a section located on the front side of the lower front panel 42 and opposite to the exhaust pipe 61 of the powertrain 6. With this configuration, the protective cover 8 can protect not only the oil pipe 7 section located directly in front of the crossbeam body 40, but also the oil pipe 7 section located on the front side of the lower front panel 42 and opposite to the exhaust pipe 61, preventing the exhaust pipe 61 from shifting backward and coming into contact with the oil pipe 7 in the event of a frontal collision, thus avoiding the safety risk of excessively high oil temperature.

[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, in the vehicle height direction, the protective cover 8 can extend downwards to the energy-absorbing structure, such that the lower end of the protective cover 8 is connected to the top surface of the energy-absorbing structure, that is, the lower end of the protective cover 8 is connected to the top surface of the energy-absorbing box 3. In this way, the top end of the protective cover 8 can be connected and fixed to the crossbeam body 40, and the lower end can be connected and fixed to the energy-absorbing box 3. The connection is stable, and the resistance to collisions is strong, providing strong protection for the impact-prone section of the oil pipe 7.

[0057] The protective cover 8 can be a hollow structure, a protective sleeve structure, or a protective plate structure. Its purpose is to enhance the protection of the oil pipe 7, add a protective cover to the oil pipe 7, and prevent sharp parts or the tips of certain parts from piercing the oil pipe 7. Preferably, the protective cover 8 can be a protective plate structure, for example, including multiple plates connected in sequence to form a protective cavity.

[0058] For example, such as Figure 5-9 As shown, the protective cover 8 may include a cover plate 81, a first side plate 82, and a second side plate, with the first side plate 82 and the second side plate arranged on both sides of the cover plate 81 in the width direction of the vehicle body; the first side plate 82, the cover plate 81, and the second side plate are connected in sequence to form a protective cavity covering the easily impacted section of the oil pipe 7. The first side plate 82, the cover plate 81, and the second side plate may be welded together or be an integral structure.

[0059] The fuel line 71 and brake line 72 can be arranged side by side on the crossbeam body 40 and connected to the crossbeam body 40 via pipe clamps. Both the fuel line 71 and brake line 72 are located inside the protective cover 8. Figure 4-6 As shown, in the section of the protective cover 8 opposite to the crossbeam body 40, or at the top of the protective cover 8, the fuel pipe 71 is located on the left and the brake pipe 72 is located on the right.

[0060] In some embodiments, the impact-prone sections of the oil pipe 7 are laid at an angle, such as... Figure 4 As shown, the energy-absorbing box 3 extends from the main beam surface 401 of the crossbeam body 40 (the crossbeam body 40 includes a vertically arranged main beam surface 401 and side beam surfaces located on the upper and lower sides of the main beam surface 401; the main beam surface 401 is also a beam surface extending vertically toward the powertrain 6) to the first side of the energy-absorbing box 3 in the width of the vehicle body, and then extends toward the vehicle floor. The side box surface of the first side of the energy-absorbing box 3 is called the first side surface 331, and a fixing component for fixing the oil pipe 7, such as a pipe clamp, is provided on the first side surface 331; it can also be said that the upper end of the impact-prone section is connected to the crossbeam body 40 and located above the energy-absorbing box 3, and the lower end is connected to the first side surface 331 of the energy-absorbing box 3.

[0061] In this embodiment, such as Figure 5-8As shown, the cover plate 81 of the protective cover 8 includes a main section 801 located above the energy-absorbing box 3 in the vehicle height direction, with the lower end of the main section 801 extending towards the energy-absorbing box 3. In the vehicle width direction, the lower end of the main section 801 includes a first portion 813 and a second portion 814. The first portion 813 is located above the top surface of the energy-absorbing box 3, and the second portion 814 is connected to an extension section 802 extending to the first side of the energy-absorbing box 3. The extension section 802 forms an angle with the main section 801. The extension section 802 is located on the first side of the energy-absorbing box 3 and is used to cover the section of the easily impacted section connected to the first side surface 331 of the energy-absorbing box 3, i.e., the lower end of the aforementioned easily impacted section. This effectively prevents the exhaust pipe 61 from coming into contact with this section of the oil pipe 7, thus preventing the oil temperature from becoming too high and further enhancing the protection of the oil pipe 7.

[0062] The extension section 802 is located on the side of the energy-absorbing box 3 facing the first side plate 82. In some embodiments, the extension section 802 is connected to the first side plate 82; that is, the first side plate 82 extends to connect with the extension section 802 of the cover plate 81. The area of ​​the first side plate 82 is larger than the area of ​​the second side plate. Thus, the extension section 802 has high structural strength and high protective performance.

[0063] In some embodiments, a weight-reducing hole 803 is provided on the first side plate 82. In this way, while ensuring the overall strength of the protective cover 8 by connecting the first side plate 82 with the extended section 802 of the cover plate 81, the hole on the first side plate 82 can reduce the overall weight, which is beneficial to reducing the net weight of the whole vehicle.

[0064] The fuel line 71 and brake line 72 are arranged side-by-side along the width of the vehicle body on the crossbeam body 40, but they can be arranged along the length of the vehicle body at the first side 331 of the energy-absorbing box 3. Therefore, in some embodiments, the dimension of the lower end of the cover plate 81 in the width direction of the vehicle body is smaller than the dimension of the upper end of the cover plate 81 in the width direction of the vehicle body. This avoids unnecessary space occupation and also helps to reduce the overall weight of the protective cover 8.

[0065] The protective cover 8 may be provided with lugs to connect and fix it to the front crossbeam assembly 4 or the energy-absorbing box 3. For example, the protective cover 8 is provided with a first lug 84, a second lug 85, and a third lug 86. Figure 6As shown, the first lug 84 is located on one side of the first side plate 82 and is connected to the crossbeam body 40 of the front crossbeam assembly 4. Specifically, it can be connected to the front beam surface 401 of the crossbeam body 40. The second lug 85 is located on one side of the second side plate and is connected to the crossbeam body 40 of the front crossbeam assembly 4. Specifically, it can be connected to the front beam surface 401 of the crossbeam body 40. The third lug 86 is located at the lower end of the cover plate 81 and is connected to the top box surface of the energy-absorbing box 3. Specifically, the third lug 86 can be located in the first part 813 of the main section 801. Each of the three lugs is provided with a connecting hole 804 for screws to pass through. In this way, the protective cover 8 is connected to the surrounding components through the three lugs, which is convenient for disassembly and assembly; and the distribution of the three lugs allows the protective cover 8 to be firmly connected, which can enhance the resistance and absorption of the impact force of the protective cover 8 when it is hit by the rearward moving component, which is beneficial to the protection of the oil pipe 7.

[0066] In the forward compartment, besides oil pipe 7, there will also be water pipes, air conditioning pipes, and other pipelines. For example... Figure 7 and Figure 9 As shown, in some embodiments, the first lug 84 may also be provided with at least two fixing points for fixing other pipes, such as a first fixing hole 805 for fixing the pipe clamp on the air conditioning pipe 9 and a second fixing hole 806 for fixing the pipe clamp on the water pipe 10. In this way, the first lug 84 can be located on the side of the water pipe 10 and the air conditioning pipe 9 facing the crossbeam body 40, so that the first lug 84 can be stacked with the pipe segments of the water pipe 10 and the air conditioning pipe 9 at this location, reducing space occupation.

[0067] In some embodiments, a partial edge at the upper end of the cover plate 81 in the width direction of the vehicle body has a first folded edge 811 that folds outward relative to the plate body, and a partial edge has an avoidance recess 812; such as Figure 6 Taking the orientation shown as an example, the left edge of the upper end of the cover plate 81 has a first folded edge 811, and the right edge has an avoidance recess 812. The avoidance recess 812 can avoid the section of the water pipe 10 located above the protective cover 8. In other words, due to the avoidance recess 812, the water pipe 10 can pass over the protective cover 8.

[0068] The first folded edge 811 is provided to prevent the edge of the plate that is close to the oil pipe 7 from puncturing the oil pipe 7 when it is impacted. Similarly, the lower edge of the cover plate 81 can be provided with a second folded edge 815 that folds outward relative to the plate; a partial edge of the first side plate 82 is provided with a third folded edge 821 that folds outward relative to the plate; and the edge of the second side plate is provided with a fourth folded edge 831 that folds outward relative to the plate.

[0069] Please see Figure 10-12In some embodiments, the energy-absorbing box 3 includes multiple crumple ribs 301 arranged sequentially along a first direction L. These crumple ribs 301 act as energy-absorbing buffers for the powertrain 6 and other devices in the engine compartment during a frontal collision, thereby reducing the amount of powertrain 6 and other devices entering the passenger compartment. It should be noted that the first direction L, as used herein, refers to a horizontal direction perpendicular to the length of the front bulkhead beam assembly 4, and also the longitudinal direction of the vehicle body structure.

[0070] Furthermore, among the multiple collapsible ribs 301 arranged in parallel, a collapsible gap 302 with a distance greater than zero is provided between adjacent collapsible ribs 301. When the front of the vehicle collides, the collapsible gap 302 deforms first, and then the collapsible ribs 301 deform, thereby achieving a layered and stable buffering effect.

[0071] Furthermore, among the multiple collapsible ribs 301 arranged in parallel, each collapsible rib 301 includes a main body region 3011 and a side region 3012 located at at least one edge of the main body region 3011. The extension direction of the side region 3012 is perpendicular to the first direction L mentioned above, and the thickness of the side region 3012 gradually decreases in the direction away from the main body region 3011. When the front of the vehicle collides, the multiple collapsible ribs 301 are compressed and deformed sequentially from front to back. During this process, the "thinned side region 3012" allows adjacent collapsible ribs 301 to first overlap each other when compressed, and then deform during the overlapping process. The force transmission direction during the deformation process is relatively stable, which helps to improve the stability of the buffering process and the final buffering effect.

[0072] Please see Figure 10 and Figure 12 In some embodiments, the upper side of the energy-absorbing box 3 is provided with one or more crumple holes 303; and / or, the lower side of the energy-absorbing box 3 is provided with one or more crumple holes 303; and / or, the front end of the energy-absorbing box 3 is provided with one or more crumple holes 303; and / or, at least a portion of the corners of the front end of the energy-absorbing box 3 are provided with crumple holes 303. For example, the central area of ​​the front end of the energy-absorbing box 3, as well as its lower left and lower right corners, are respectively provided with crumple holes 303. The aforementioned crumple holes 303 not only serve as energy-absorbing buffers but also help reduce the vehicle's weight.

[0073] Please see Figure 10 and Figure 12In some embodiments, the thickness 'a' of the front end of the energy-absorbing box 3 is less than the thickness 'b' of the rear end. Therefore, assuming the projected area of ​​the front end of the energy-absorbing box 3 away from the front crossbeam assembly 4 in the vertical plane is S1, and the projected area of ​​the rear end of the energy-absorbing box 3 near the front crossbeam assembly 4 in the vertical plane is S2, then S2 > S1. This structure is beneficial for ensuring the stable deformation of the energy-absorbing box 3 during a frontal collision, thus ensuring the stability of the energy absorption and buffering process.

[0074] Preferably, please refer to Figure 12 In some embodiments, the energy-absorbing box 3 is composed of a box body unit 31 and a cover unit 32. Specifically: the lower side of the box body unit 31, which is the lower side of the energy-absorbing box 3, is provided with a first collapse region 311, which includes multiple first collapse ribs 3111 arranged sequentially along a first direction L; the upper side of the cover unit 32, which is the upper side of the energy-absorbing box 3, is provided with a second collapse region 321, which includes multiple second collapse ribs 3211 arranged sequentially along the first direction L; and the cover unit 32 is fastened to the upper opening of the box body unit 31.

[0075] In addition, the box unit 31 also includes a first vertical plate 312, a first top plate 314, and a first connecting part 313, wherein: the first vertical plate 312 is located on the left and right sides of the first collapse area 311 and bends upward; the first top plate 314 is located on the front side of the first collapse area 311 and bends upward; the first connecting part 313 is located at the rear end of the first vertical plate 312 and bends outward for connection with the front side of the lower front panel 42 in the front beam assembly 4. Correspondingly, the cover unit 32 also includes a second vertical plate 322, a second top plate 324, and a second connecting part 323, wherein: the second vertical plate 322 is located on the left and right sides of the second collapse area 321 and bends downward; the second top plate 324 is located on the front side of the second collapse area 321 and bends downward; the second connecting part 323 is located at the rear end of the second collapse area 321 and bends upward for connection with the front beam assembly 4. Specifically, the second connecting part 323 is located at the rear end of the top surface of the energy-absorbing box 3, and the second connecting part 323 is connected to the front side of the lower front panel 42 in the front beam assembly 4. When the cover unit 32 and the box unit 31 are fastened together to form the energy-absorbing box 3, the second vertical plate 322 and the second top plate 324 of the cover unit 32 are located outside the first vertical plate 312 and the first top plate 314 of the box unit 31 and are welded to them, respectively.

[0076] In some embodiments, the energy-absorbing box 3 is a sheet metal structural component. For example, the box unit 31 and the cover unit 32 mentioned above are different sheet metal components, and are respectively provided with shrinkage ribs or shrinkage hole structures. However, it is not limited to this. The energy-absorbing structure (e.g., the energy-absorbing box 3) fixedly connected to the front crossbeam assembly 4 provided in this application can also adopt other forms of structural components or other different material designs to achieve different or substantially the same performance effects.

[0077] During the production process, the first vertical plates 312 on the left and right sides of the box unit 31 and the second vertical plates 322 on the left and right sides of the cover unit 32 are welded together to form the energy-absorbing box 3. Then, the energy-absorbing box 3 is installed to the front side of the lower front panel 42 of the front beam assembly 4 through the first connecting part 313 located at the rear of the box unit 31 and the second connecting part 323 located at the rear of the cover unit 32. The rear side of the lower front panel 42 is connected to the central channel 5. Specifically, the first connecting part 313, the lower front panel 42, and the central channel 5 can be fixedly connected by welding three layers of plates simultaneously. Similarly, the second connecting part 323, the lower front panel 42, and the central channel 5 can also be fixedly connected by welding three layers of plates simultaneously. However, this is not the only option. In other embodiments, the energy-absorbing box 3, the front beam assembly 4, and the central channel 5 can also be fixedly connected by fasteners, such as screws.
