Description

Vehicle body structure and vehicle

[0001] The present application claims priority to the Chinese patent application No. 202423044209.6, filed on December 10, 2024, entitled "Vehicle body structure and vehicle", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of vehicle manufacturing, in particular to a vehicle body structure and a vehicle provided with the same. BACKGROUND

[0003] Fuel pipes need to be arranged from the front compartment to the rear of the vehicle on a fuel vehicle, such as fuel pipes connecting the fuel tank and the front compartment engine and brake oil pipes from the front compartment to the rear wheels. With the increasing functions of current vehicles, the number of components is increasing, and the space in the front compartment is becoming more crowded, and the arrangement of the oil pipe has low adjustability. Usually, at least part of the oil pipe is located between the front wall cross beam assembly (usually located below the front windshield, between the front compartment and the passenger compartment) and the engine assembly and other components. In addition, the distance between the engine assembly and the front wall cross beam on the current vehicle model is small, and when the vehicle head collides, the components in the front compartment such as the engine assembly will move backward and easily collide with the front wall cross beam assembly, and the oil pipe in the front compartment is easily punctured by the tip of the backward moving component, resulting in damage and safety risks caused by oil leakage.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

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

[0048] Referring to Figs. 1-12, embodiments of the present application provide a vehicle body structure including a front bulkhead cross beam assembly 4 and an oil pipe 7, the front bulkhead cross beam assembly 4 is disposed behind the power assembly 6 in the vehicle length direction (X direction shown in the drawings), usually at the position below the front windshield and between the front compartment and the passenger compartment. As shown in Fig. 2, the front bulkhead cross beam assembly 4 includes a cross beam body 40, a front bulkhead panel 41 above the cross beam body 40, and a front bulkhead lower panel 42 below the cross beam body 40. Fig. 1 shows a schematic view of the connection of the front bulkhead cross beam assembly 4 with other components of the vehicle body in some embodiments. The rear side of the front bulkhead cross beam assembly 4 is connected to the vehicle floor, and the two ends in the vehicle width direction (Y direction shown in the drawings) are connected to the first longitudinal beam 21 and the second longitudinal beam 22, both of which are connected to the front crash beam 1. The front crash beam 1, the first longitudinal beam 21, the front bulkhead cross beam assembly 4, and the second longitudinal beam 22 are sequentially connected end to end to form a front compartment frame in the shape of a mouth.

[0049] The oil pipe 7 usually includes a fuel pipe 71 connecting the engine and the fuel tank, and a brake pipe 72 leading from the hydraulic oil tank to each wheel. The oil pipe 7 is usually laid from the front of the front bulkhead cross beam assembly 4 to the front bulkhead cross beam assembly 4, and then extends backward along the vehicle floor, as shown in Fig. 4. A partial section of the oil pipe 7 is located between the cross beam body 40 of the front bulkhead cross beam assembly 4 and the power assembly 6 (in the front bulkhead cross beam assembly 4, the cross beam body 40 is the area closest to the power assembly 6, and the rearward movement of the power assembly 6 is in collision with the front beam surface 401 of the cross beam body 40), for ease of description, this partial section is referred to herein as the vulnerable section. In the present application, the vehicle body structure is also provided with a protective cover 8 and an energy-absorbing structure, the energy-absorbing structure is connected to the front bulkhead cross beam assembly 4 and at least partially located on the front side of the front bulkhead cross beam assembly 4, so that when the front of the vehicle is subjected to a collision causing the power assembly 6 to move backward, it will first contact and absorb the collapse of the power assembly 6, reducing the impact of the power assembly 6 on the front bulkhead cross beam assembly 4 or preventing the power assembly 6 from impacting the front bulkhead cross beam assembly 4; and the protective cover 8 is also provided on the front side of the front bulkhead cross beam assembly 4, connected to the front bulkhead cross beam assembly 4 and configured to cover the vulnerable section of the oil pipe 7 between the cross beam body 40 and the power assembly 6. When the power assembly 6 moves backward, the impact force is reduced by the energy-absorbing structure, and even if the power assembly 6 impacts the protective cover 8, the impact will be reduced. In addition, the protective cover 8 covers and protects the oil pipe 7, which will continue to offset the impact force and block the sharp end of the component from piercing the oil pipe 7, thereby significantly reducing the impact damage to the oil pipe 7 and effectively protecting the vulnerable section of the oil pipe 7.

[0050] That is, the vehicle body structure provided by the present application is provided with an energy-absorbing structure and a protective cover 8 covering the oil pipe 7 on the front side of the front cross beam assembly 4. When the front part of the vehicle collides, the power assembly 6 moves towards the front cross beam assembly 4, and first collides with the energy-absorbing structure. The energy-absorbing structure effectively absorbs the collision energy, mitigates the impact of the power assembly 6, effectively reduces the impact of the power assembly 6 on the front cross beam assembly 4 and the oil pipe 7, and the protective cover 8 covering the oil pipe 7 also absorbs the collision of the power assembly 6, disperses the impact force, and effectively resists the piercing of the tip of the rearward moving component on the oil pipe 7, effectively protecting the oil pipe 7. It can be seen that the vehicle body structure provided by the present application can reduce the impact of the power assembly 6 on the front cross beam assembly 4, and enhance the protection of the oil pipe 7, reduce the safety risk that the oil pipe 7 may be damaged due to collision and cause oil leakage, and improve the crashworthiness and safety of the vehicle.

[0051] At the same time, due to the arrangement of the energy-absorbing structure, the energy-absorbing structure can directly play a role of energy-absorbing and buffering for the power assembly 6 and other devices in the front compartment when the front part of the vehicle collides, reducing the amount of the power assembly 6 and other devices in the front compartment into the passenger compartment, thereby avoiding the problem of excessive intrusion of the front cross beam assembly 4 into the front compartment and poor crashworthiness of the vehicle. Moreover, in the vehicle body structure provided by the present application, the front side of the front cross beam assembly 4 is increased with the energy-absorbing structure, which can be targeted to absorb energy and buffer for power assemblies 6 of different sizes, thereby facilitating the uniformity of the power assembly 6 installation point. In addition, the arrangement of the energy-absorbing structure can also reduce the strength requirement of the front cross beam assembly 4, which is conducive to reducing the design difficulty of the front cross beam assembly 4.

[0052] Please refer to FIGS. 2-6, the front cross beam assembly 4 includes a front cross beam plate 41, a cross beam body 40 and a front cross beam lower plate 42 connected in sequence from top to bottom. The upper end of the front cross beam lower plate 42 is connected with the cross beam body 40, and the lower end of the front cross beam lower plate 42 extends downward and rearward relative to the upper end and is configured to be connected with the vehicle floor. The middle channel 5 is connected with the front cross beam lower plate 42 and located at the rear side of the front cross beam lower plate 42. Specifically, the energy-absorbing structure is connected to the front cross beam lower plate 42, located on the front side of the front cross beam lower plate 42, and extends towards the power assembly 6 or the front bumper beam 1.

[0053] Specifically, the energy-absorbing structure can be an energy-absorbing box 3, or any other structure with energy-absorbing effect. For ease of understanding, the energy-absorbing box 3 is taken as an example for specific description herein.

[0054] The energy absorption box 3 is located behind the power assembly 6 and connected with the front side of the lower panel 42 of the front wall. In some embodiments, referring to FIG. 1 and FIG. 2, the energy absorption box 3 is located on the longitudinal extension line of the middle channel 5, that is, the energy absorption box 3 and the middle channel 5 are respectively located on the front and rear sides of the lower panel 42 of the front wall, and the projections of the energy absorption box 3 and the middle channel 5 in the front-rear direction of the vehicle at least partially overlap. In this way, when a collision occurs at the front of the vehicle, a force transmission path can be formed from the energy absorption box 3 to the middle channel 5, which can better absorb energy and more effectively reduce the damage of the collision to the front cross beam assembly 4 and the passenger compartment.

[0055] In the vehicle height direction, that is, the Z direction shown in FIG. 1, the protective cover 8 includes a section located on the front side of the beam body 40 and a section located on the front side of the lower panel 42 of the front wall and opposite to the exhaust pipe 61 of the power assembly 6. In this way, the protective cover 8 not only protects the section of the oil pipe 7 located on the front side of the beam body 40, but also protects the section of the oil pipe 7 located on the front side of the lower panel 42 of the front wall and opposite to the oil pipe 61, preventing the exhaust pipe 61 from moving backward and being in contact with the oil pipe 7 when a collision occurs at the front of the vehicle, and avoiding the risk of excessively high oil temperature.

[0056] In some embodiments, as shown in FIG. 5 and FIG. 6, in the vehicle height direction, the protective cover 8 can extend downward to the energy absorption structure, for example, the lower end of the protective cover 8 is connected with the top surface of the energy absorption structure, that is, the lower end of the protective cover 8 is connected with the top surface of the energy box 3. In this way, the top end of the protective cover 8 can be connected with the beam body 40 for fixation, and the lower end can be connected with the energy box 3 for fixation, which is stable and strong in resistance to collision and strong in protection of the oil pipe 7.

[0057] The protective cover 8 can be a hollow structure, a protective sleeve structure, or a protective plate structure. The purpose is to enhance the protection of the oil pipe 7, add a protective cover to the oil pipe 7, and resist the piercing of the oil pipe 7 by sharp components or the tips of certain components. Preferably, the protective cover 8 can be a protective plate structure, for example, including a plurality of plate bodies connected in sequence to form a protective cavity.

[0058] For example, as shown in FIG. 5-9, the protective cover 8 can include a cover plate 81, a first side plate 82, and a second side plate, which are arranged on both sides of the cover plate 81 in the vehicle width direction; the first side plate 82, the cover plate 81, and the second side plate are connected in sequence and surround a protective cavity covering the collision-prone section of the oil pipe 7. The first side plate 82, the cover plate 81, and the second side plate can be welded together or can be an integral structure.

[0059] The fuel pipe 71 and the brake pipe 72 can be arranged side by side on the beam body 40 and connected to the beam body 40 by pipe clamps. The fuel pipe 71 and the brake pipe 72 are both located in the protective cover 8, as shown in FIGS. 4-6. In the section of the protective cover 8 opposite to the beam body 40, or in other words, at the top end of the protective cover 8, the fuel pipe 71 is located on the left side and the brake pipe 72 is located on the right side.

[0060] In some embodiments, the collision-prone section of the oil pipe 7 is arranged obliquely, as shown in FIG. 4, extending from the front beam face 401 of the beam body 40 (the beam body 40 includes a vertically arranged front beam face 401 and side beam faces located on the upper and lower sides of the front beam face 401, and the front beam face 401 is also a beam face extending in the vertical direction towards the power assembly 6) to the first side of the energy absorption box 3 in the vehicle body width direction, and then extending to the vehicle floor. The side box face of the first side of the energy absorption box 3 is referred to as the first side face 331, and the first side face 331 is provided with a fixing member such as a pipe clamp for fixing the oil pipe 7. In other words, the upper end of the collision-prone section is connected to the beam body 40 and located above the energy absorption box 3, and the lower end is connected to the first side face 331 of the energy absorption box 3.

[0061] In this embodiment, as shown in FIGS. 5-8, the cover plate 81 of the protective cover 8 includes a main section 801 located above the energy absorption box 3 in the vehicle body height direction, and the lower end of the main section 801 extends to the energy absorption box 3. The lower end of the main section 801 in the vehicle body width direction includes a first portion 813 located above the top face of the energy absorption box 3 and a second portion 814 connected to an extension section 802 extending to the first side of the energy absorption box 3, and the extension section 802 has an included angle with the main section 801. The extension section 802 is located on the first side of the energy absorption box 3 and is configured to cover the section of the collision-prone section connected to the first side face 331 of the energy absorption box 3, i.e., the lower end of the collision-prone section. In this way, the phenomenon of the exhaust pipe 61 adhering to this section of the oil pipe 7 to cause the oil temperature to be too high can be effectively prevented, and the protection of the oil pipe 7 is further enhanced.

[0062] The extension section 802 is located on the side of the energy absorption box 3 facing the first side plate 82. In some embodiments, the extension section 802 is connected to the first side plate 82, or in other words, the first side plate 82 extends to be connected to the extension section 802 of the cover plate 81. The area of the first side plate 82 is greater than that of the second side plate. In this way, the extension section 802 has high structural strength and high protection.

[0063] In some embodiments, the first side plate 82 is provided with a weight-reducing hole 803. In this way, on the basis of the first side plate 82 being connected to the extension section 802 of the cover plate 81 to ensure the overall strength of the protective cover 8, the hole in the first side plate 82 can reduce the overall weight, which is beneficial to reducing the overall net weight of the vehicle.

[0064] The fuel pipe 71 and the brake pipe 72 are arranged side by side on the beam body 40 in the vehicle width direction, but are arranged in the vehicle length direction at the first side face 331 of the energy absorption box 3. Therefore, in some embodiments, the size of the lower end of the cover plate 81 in the vehicle width direction is smaller than the size of the upper end of the cover plate 81 in the vehicle width direction. In this way, unnecessary space occupation is avoided, and the overall weight of the protective cover 8 is reduced.

[0065] The protective cover 8 can be provided with lugs to be connected to the front beam assembly 4 or the energy absorption box 3 for fixation. For example, the protective cover 8 is provided with a first lug 84, a second lug 85 and a third lug 86. As shown in FIG. 6, the first lug 84 is arranged on one side of the first side plate 82 and connected to the beam body 40 of the front beam assembly 4, specifically, the front beam face 401 of the beam body 40. The second lug 85 is arranged on one side of the second side plate and connected to the beam body 40 of the front beam assembly 4, specifically, the front beam face 401 of the beam body 40. The third lug 86 is arranged at the lower end of the cover plate 81 and connected to the top box face of the energy absorption box 3. Specifically, the third lug 86 can be arranged on the first local part 813 of the main section 801. The three lugs are all provided with connection holes 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. The distribution of the three lugs enables the stable connection of the protective cover 8, and when the protective cover 8 is impacted by the rearward moving components, the resistance and absorption of the impact force is enhanced, which is beneficial to the protection of the fuel pipe 7.

[0066] In the front compartment, in addition to the fuel pipe 7, there are also water pipes, air conditioning pipes and other pipelines. As shown in FIG. 7 and FIG. 9, in some embodiments, the first lug 84 can be further provided with at least two fixing points for fixing other pipelines, for example, a first fixing hole 805 for fixing a pipe clamp of the air conditioning pipe 9 and a second fixing hole 806 for fixing a pipe clamp of 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 beam 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 position, reducing the space occupation.

[0067] In some embodiments, the local edge of the upper end of the cover plate 81 in the vehicle width direction has a first folded edge 811 folded outward relative to the plate body, and the local edge has an avoiding recess 812. For example, as shown in FIG. 7, the left edge of the upper end of the cover plate 81 has the first folded edge 811, and the right edge has the avoiding recess 812. The avoiding recess 812 can avoid the segment of the water pipe 10 above the protective cover 8, or in other words, the water pipe 10 can pass above the protective cover 8 due to the avoiding recess 812.

[0068] The first folding edge 811 can avoid the edge of the plate body close to the oil pipe 7 from piercing the oil pipe 7 when the edge is impacted. Similarly, the lower edge of the cover plate 81 can be provided with a second folding edge 815 folded outward relative to the plate body; a part of the edge of the first side plate 82 can be provided with a third folding edge 821 folded outward relative to the plate body; and the edge of the second side plate can be provided with a fourth folding edge 831 folded outward relative to the plate body.

[0069] Referring to FIGS. 10-12, in some embodiments, the energy-absorbing box 3 includes a plurality of collapse ribs 301 arranged in sequence along a first direction L. The collapse ribs 301 can absorb energy and buffer the power assembly 6 and other devices in the engine compartment when a collision occurs at the front of the vehicle, thereby reducing the amount of the power assembly 6 and other devices in the engine compartment entering the passenger compartment. It should be noted that the first direction L herein refers to the horizontal direction perpendicular to the length direction of the front cross beam assembly 4, and is also the front-rear direction of the vehicle on which the vehicle body structure is located.

[0070] Further, in the plurality of collapse ribs 301 arranged side by side, a distance greater than zero is provided between adjacent collapse ribs 301. When a collision occurs at the front of the vehicle, the collapse gap 302 deforms first, and then the collapse ribs 301 deform, thereby obtaining a stable buffering effect with clear levels.

[0071] Further, in the plurality of collapse ribs 301 arranged side by side, each collapse rib 301 includes a main plate area 3011, and a side edge area 3012 located at at least one side edge of the main plate area 3011. The extension direction of the side edge area 3012 is perpendicular to the first direction L described above, and the thickness of the side edge area 3012 gradually decreases in a direction away from the main plate area 3011. When a collision occurs at the front of the vehicle, the plurality of collapse ribs 301 are sequentially extruded from front to back. In this process, the "thinning side edge area 3012" can make adjacent collapse ribs 301 first overlap each other when extruded, and then deform during the overlapping process, with a relatively stable force transmission direction during the deformation process, thereby facilitating the stability of the buffering process and the final buffering effect.

[0072] Referring to FIGS. 10 and 12, in some embodiments, the upper side of the energy-absorbing box 3 is provided with one or more collapse holes 303; and / or, the lower side of the energy-absorbing box 3 is provided with one or more collapse holes 302; and / or, the front end of the energy-absorbing box 3 is provided with one or more collapse holes 303, and / or, at least part of the corners of the front end of the energy-absorbing box 3 is provided with a collapse hole 303. For example, the front end center area, the lower left corner and the lower right corner of the energy-absorbing box 3 are respectively provided with a collapse hole 303. The above-mentioned collapse holes 303 not only can absorb energy and buffer, but also can reduce the weight of the vehicle body.

[0073] Please refer to FIG. 10 and FIG. 12, in some embodiments, the front end thickness a of the box body of the energy absorption box 3 is less than the rear end thickness b of the box body.

Correspondingly, the cover body unit 32 further 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 is bent downward; the second top plate 324 is located on the front side of the second collapse area 321 and is bent downward; and the second connecting part 323 is located at the rear end of the second collapse area 321 and is bent upward, and is configured to be connected with the front wall transverse beam assembly 4. Specifically, the second connecting part 323 is arranged at the rear end of the top surface of the energy absorption box 3, and the second connecting part 323 is connected with the front side of the front wall lower plate 42 in the front wall transversebeam assembly 4. When the cover body unit 32 and the box body unit 31 are clamped to form the energy absorption box 3, the second vertical plate 322 and the second top plate 324 of the cover body unit 32 are located outside the first vertical plate 312 and the first top plate 314 of the box body unit 31 respectively and are welded therewith.

[0076] In some embodiments, the energy absorption box 3 is a sheet metal structure. For example, the box unit 31 and the cover unit 32 mentioned above are respectively different sheet metal structures, and are respectively provided with a collapse rib or a collapse hole structure. However, it is not limited thereto, and the energy absorption structure (for example, the energy absorption box 3) provided in the present application and fixedly connected to the front cross beam assembly 4 can also adopt other forms of structure or be designed with other materials to achieve different or basically the same performance effects.

[0077] In the production process, first, 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 respectively welded to form the energy absorption box 3; then the energy absorption box 3 is installed to the front side of the front lower plate 42 of the front cross beam assembly 4 through the first connecting part 313 located at the rear side of the box unit 31 and the second connecting part 323 located at the rear side of the cover unit 32, and the rear side of the front lower plate 42 is connected with the middle channel 5. Specifically, the first connecting part 313, the front lower plate 42 and the middle channel 5 can be fixedly connected by adopting a three-layer plate welding mode, and similarly, the second connecting part 323, the front lower plate 42 and the middle channel 5 can also be fixedly connected by adopting a three-layer plate welding mode. However, it is not limited thereto, and in other embodiments, the fixed connection between the energy absorption box 3, the front cross beam assembly 4 and the middle channel 5 can also be achieved by a fastener connection mode such as screwing.
