[0030] To address the technical problems existing in related technologies, this application provides a vehicle. Against the backdrop of the automotive industry undergoing a profound transformation from traditional fuel-powered to diversified clean energy-powered vehicles, vehicles can be mainly divided into fuel-powered vehicles, natural gas-powered vehicles, and new energy vehicles representing the future direction. New energy vehicles, as the core of this transformation, mainly include pure electric vehicles, hybrid electric vehicles, and range-extended electric vehicles. Unlike traditional vehicles that rely solely on internal combustion engines, one of the core characteristics of new energy vehicles is the inclusion of a large battery pack. The battery pack not only provides power to the drive motor but also acts as the vehicle's core operating power source, providing energy to the drive system, control system, in-vehicle entertainment system, and all auxiliary equipment, making it an indispensable foundation for their normal operation. The vehicle includes a body component 10, which, as part of the vehicle's body structure, bears the main load of the vehicle and can effectively and evenly distribute the forces borne by the vehicle, avoiding excessive force concentration that could lead to structural collapse.

[0031] To address the technical problems existing in related technologies, this application provides a vehicle body component 10, see [link to relevant documentation]. Figures 1 to 3 , Figure 1 This is a schematic diagram of an embodiment of the vehicle body component provided in this application. Figure 2 This is an exploded structural diagram of an embodiment of the vehicle body component provided in this application. Figure 3 This is a schematic diagram of an embodiment of the second vehicle body pillar provided in this application.

[0032] The vehicle body assembly 10 includes a first body pillar 100, a second body pillar 200, a side beam connecting plate 300, and a first tube beam 340. The first body pillar 100 extends along a first direction X; the second body pillar 200 extends along the first direction X, and the second body pillar 200 and the first body pillar 100 are spaced apart in a second direction Y, where the first direction X and the second direction Y intersect; the side beam connecting plate 300 extends along the second direction Y and connects the first body pillar 100 and the second body pillar 200 respectively; the first tube beam 340 extends along the second direction Y and forms a hollow tube extending along the second direction Y, wherein the side beam connecting plate 300 forms a side beam groove 330 extending along the second direction Y, and the first tube beam 340 is located in the side beam groove 330 and connected to the side beam connecting plate 300.

[0033] The vehicle body assembly 10 can be used as part of the vehicle body structure. The body pillars serve as the main load-bearing structures for the side door openings. The first body pillar 100 and the second body pillar 200 are spaced apart in the second direction Y and extend along the first direction X, where the first direction X is the vertical direction of the vehicle and the second direction Y is the horizontal direction of the vehicle. The first body pillar 100 and the second body pillar 200 can have open cross-sections or be formed into complex polygonal closed cross-sections.

[0034] When the vehicle body assembly 10 is installed on the vehicle, the side beam connecting plate 300 extends along the length of the vehicle and may be provided with mounting holes for fixing to the upper part of the vehicle or installing other components, and also serves to withstand the pressure of the vehicle roof. Typically, the side beam connecting plate 300 can be a plate-like structure, a connecting through hole, or a bent flange structure. Preferably, the side beam connecting plate 300 is a structure composed of multiple plates connected together, with an opening on one side forming a side beam groove 330. The side beam groove 330 can be a single groove or multiple parallel grooves, and can also be configured to accommodate other functional components. Preferably, the side beam groove 330 is single and continuous, running the entire length of the side beam connecting plate 300 along the second direction Y, so that the cross-section of the side beam connecting plate 300 in the first direction X presents a "U" shape, with its opening facing the width direction of the vehicle. The side beam groove 330 and the side beam connecting plate 300 work together to form the load-bearing structure of the vehicle body component 10. At the same time, the first body pillar 100 and the second body pillar 200 are respectively connected to the side beam connecting plate 300 in the first direction X.

[0035] The first tube beam 340 adopts a hot-expansion tube beam structure and extends in the longitudinal direction of the vehicle, located inside the side beam groove 330. Its cross-section presents a closed annular structure, which can evenly distribute the stress in the extension direction of the first tube beam 340 at the top of the vehicle, avoiding stress concentration. It bears the main load-bearing component inside the side beam connecting plate 300. Due to the hot-expansion molding process, the first tube beam 340 has high strength, with a tensile strength of up to 2000-2200MPa and a material thickness of 1.4mm.

[0036] The side beam groove 330 structure alters the cross-sectional shape of the side beam connecting plate 300, creating the side beam groove 330. This groove design integrates functions and provides space for the fixation of the first tube beam 340. The side beam connecting plate 300 can be made of duplex steel with a tensile strength exceeding 780 MPa and a thickness of 1.2 mm. The side beam connecting plate 300 and the first tube beam 340 cooperate with each other. The first tube beam 340 bears the main pressure within the side beam groove 330, allowing the thickness of the side beam connecting plate 300 to be further reduced to 1.2 mm. This reduces the weight of the vehicle body component 10 while simultaneously improving vehicle strength, achieving the vehicle's lightweight requirements. Furthermore, a first body pillar 100 and a second body pillar 200 are fixed on the side of the side beam connecting plate 300 away from the top of the vehicle body. The force transmission path can reach the body pillars through the side beam connecting plate 300, further enhancing the strength of the vehicle body component 10 and preventing poor force transmission during vehicle collisions, thus avoiding the risk of brittle fracture.

[0037] Furthermore, the side beam connecting plate 300 includes a first top plate 310 and two first side plates 320. The first top plate 310 and the two first side plates 320 extend along the second direction Y. The two first side plates 320 are located on the same side of the first top plate 310 and are respectively connected to the first top plate 310 to form a side beam groove 330. The first tube beam 340 is connected to at least one of the first top plate 310 and the two first side plates 320.

[0038] Specifically, the side beam connecting plate 300, which directly connects to the vehicle body, serves both load-bearing and connecting functions. It consists of three plates: a first roof plate 310 and two first side plates 320. All three plates extend along the second direction Y. The two first side plates 320 are simultaneously fixedly connected to both sides of the first roof plate 310 in the first direction X, symmetrically distributed about the first roof plate 310, i.e., located on the same side of the first roof plate 310. This together defines and forms a lateral opening side beam groove 330 that penetrates the side beam connecting plate 300 along the first direction X. The three plate structures can be integrally formed or assembled from three independent plates by welding or screwing. The connection method between the first roof plate 310 and the two first side plates 320 includes, but is not limited to, an arc-shaped bending connection; it can also be spot welding or other mechanical connections. The first tube beam 340, fixed in the side beam groove 330, can be connected individually to the first top plate 310, or individually to one of the two first side plates 320, or simultaneously to two different plates, or connected together to the first top plate 310 and the two first side plates 320. The connection methods include, but are not limited to, welding, screwing, or other mechanical connections. As an open section, the side beam groove 330 is prone to deformation of the side beam connecting plate 300 under vehicle roof pressure or side impact. By fixing the first tube beam 340 inside the side beam groove 330, stress can be evenly transmitted and dispersed, effectively limiting the tendency of the side beam connecting plate 300 to deform. The two work synergistically to improve the compressive stability of the vehicle body component 10, enabling the structure to withstand greater loads.

[0039] Furthermore, the first body pillar 100 is connected to both the first roof panel 310 and the two first side panels 320, and the second body pillar 200 is connected to one first side panel 320.

[0040] The first body pillar 100 and the second body pillar 200 extend in the first direction X. Both are connected to the side beam connecting plate 300, which can support the roof and connect the sill longitudinal beam.

[0041] The first body pillar 100 extends in the vertical direction of the vehicle. One end of the first body pillar 100 in the first direction X is connected to one end of the side beam connecting plate 300 in the second direction Y, and the other end is connected to the sill longitudinal beam. The first body pillar 100 is also composed of three plate structures, presenting a groove that runs through the first body pillar 100 along the first direction X. The first body pillar 100 is connected to the first roof plate 310 and the two first side plates 320 at the same time, so that the side beam groove 330 of the side beam connecting plate 300 is connected to the groove of the first body pillar 100, presenting an inverted "L" shaped groove. The first body pillar 100 can be made of duplex steel with a tensile strength of 760-800MPa and a thickness of 1.4mm. The side beam connecting plate 300 is connected to the first body pillar 100, forming an upper and lower structure in the first direction X. The first body pillar 100 is also connected to the front of the vehicle in the second direction Y. When the vehicle is involved in a frontal offset collision, the impact force will act on the first body pillar 100 and be transmitted to the side beam connecting plate 300. The two work together to avoid stress concentration, thereby playing a safety protection role.

[0042] The second body pillar 200 is connected at one end to the other end of the side beam connecting plate 300 in the first direction X, and at the other end of the second body pillar 200 in the first direction X to the sill longitudinal beam. The second body pillar 200 is connected to the first side plate 320 of the side beam connecting plate 300 that is away from the roof and is located in the middle of the side beam connecting plate 300 in the second direction Y. This can disperse the force on the roof along the second direction Y, thereby improving the stress strength in the middle of the roof.

[0043] The second body pillar 200 adopts a structure design that is narrower at the top and wider at the bottom in the vertical direction of the vehicle. Its structural material can be a thermoformed material with a tensile strength of 980-1120 MPa and a thickness of 1.4 mm. In the event of a side collision, the second body pillar 200 is a primary load-bearing component, working together with the sill beams to effectively absorb and disperse the side impact force. Furthermore, the narrower-at-the-top, wider-at-the-bottom design allows the end of the second body pillar 200 furthest from the roof to withstand greater strength, making it less prone to crumpling.

[0044] The side beam connecting plate 300, the first body pillar 100, and the second body pillar 200 are closely connected to form the outer side frame of the vehicle. In a frontal collision, the impact force acts on the first body pillar 100, and part of the impact force is transferred to the second body pillar 200 through the side beam connecting plate 300, avoiding stress concentration. In a side collision, the impact force acts on the second body pillar 200 and is transferred upward to the side beam connecting plate 300, thus dispersing the force to the first body pillar 100. The combined effect of these three components optimizes the force transmission path and enhances the strength of the outer side frame.

[0045] Furthermore, one end of the first tube beam 340 extends close to the first vehicle body pillar 100, and the distance between the other end of the first tube beam 340 and the first vehicle body pillar 100 is greater than the distance between the second vehicle body pillar 200 and the first vehicle body pillar 100.

[0046] The first tube beam 340 extends along the second direction Y, penetrates and is fixed inside the side beam groove 330. One end of the first tube beam 340 is adjacent to or connected to the end of the first body pillar 100 away from the sill longitudinal beam, and the other end extends along the front direction of the vehicle away from the second body pillar 200. The straight-line distance between the end extending along the front direction of the vehicle and the end adjacent to or connected to the first body pillar 100 is greater than the spacing width between the first body pillar 100 and the second body pillar 200. The second body pillar 200 is located between the first tube beams 340 in the second direction Y. The two cooperate with each other to increase the force transmission path and thus improve the strength of the vehicle body assembly 10.

[0047] In some embodiments, the vehicle body assembly 10 includes at least one second tubular beam 210 extending along a first direction X and connected to a second body pillar 200. Specifically, the second tubular beam 210 has a closed cross-section and extends above and below the vehicle. There may be only one second tubular beam 210, or two or more. Preferably, there are two second tubular beams 210, which may be located on the same side of the second body pillar 200 or symmetrically distributed on both sides of the second body pillar 200. The second tubular beams 210 and the second body pillar 200 are connected to form a composite load-bearing structure, wherein the connection method includes, but is not limited to, welding, bolting, or connection via connecting plates. The second tube beam 210 is manufactured using a hot air expansion molding process, with a tensile strength of up to 2000-2200MPa and a material thickness of 1.5mm. The second tube beam 210 is connected to the second body pillar 200, and when the vehicle is subjected to a side collision, the two work together to effectively increase the force transmission path, thereby dispersing the impact force and improving the strength of the vehicle body component 10.

[0048] Furthermore, one end of the second tube beam 210 is close to the side beam connecting plate 300, and the other end is close to the second body pillar 200 within one-third to two-thirds of its length in the first direction X.

[0049] The second tube beam 210 extends in the second direction Y, with one end adjacent to the side beam connecting plate 300 and connected to the right angle of the door opening of the side outer frame. The other end extends towards the bottom of the vehicle to within one-third to two-thirds of the length of the second body pillar 200 in the first direction X. That is, the length of the second tube beam 210 in the first direction X is between one-third and two-thirds of the length of the second body pillar 200 in the first direction X, ensuring that the end of the second tube beam 210 near the top of the vehicle is adjacent to or connected to the side beam connecting plate 300, preferably one-half the length of the second body pillar 200. The second body pillar 200 has the second tube beam 210 working together in the upper part near the top of the vehicle. Therefore, when the vehicle is subjected to a side impact and the force threshold of the second body pillar 200 is reached, the upper part of the second body pillar 200 is less likely to be damaged due to the cooperation of the second tube beam 210, which will cause the lower part of the second body pillar 200 to collapse first, thus maximizing the protection of the area above the shoulders of the occupant.

[0050] Furthermore, the vehicle body assembly 10 also includes a door hinge 220, which is connected to the second body pillar 200. The door hinge 220 is located at the end of the second tube beam 210 away from the side beam connecting plate 300. The door hinge 220 is located at the middle position of the second body pillar 200 along the first direction X. The door hinge 220 is the rotation axis for opening and closing the door, ensuring that the door can rotate smoothly around a fixed and precise axis. The second tube beam 210 extends from one end along the bottom of the vehicle to the door hinge, meaning that the length of the second tube beam 210 extending along the bottom of the vehicle near the side beam connecting plate 300 is half the length of the second body pillar 200. This further ensures the load-bearing strength of the upper part of the second body pillar 200 near the side beam connecting plate 300.

[0051] In some embodiments, the second vehicle body pillar 200 includes a second roof plate 230 and two second side plates 240, the second roof plate 230 and the two second side plates 240 extending along a first direction X, the two second side plates 240 being located on the same side of the second roof plate 230 and respectively connected to the second roof plate 230, and the second tube beam 210 being connected to the second side plates 240.

[0052] Specifically, the second body pillar 200, serving as the load-bearing support for the vehicle's roof and connecting the side beam plate 300 and the sill longitudinal beam, is composed of three plates: a second roof plate 230 and two second side plates 240. These three plates extend along a first direction X. The two second side plates 240 are simultaneously fixedly connected to the second roof plate 230 on both sides along the vehicle's longitudinal direction, symmetrically distributed about the second roof plate 230, i.e., located on the same side of the second roof plate 230, thus collectively defining and forming a groove structure that runs through the second body pillar 200 along the first direction X. The three plate structures can be integrally formed or assembled from three independent plates by welding or screwing. The connection method between the second roof plate 230 and the two second side plates 240 includes, but is not limited to, an arc-shaped bending connection; spot welding or other mechanical connections are also possible. The second tube beam 210 is connected to the second body pillar 200 and can be located either near the groove in the second side plate 240 or away from the groove in the second side plate. The second tube beam 210 and the second body column work together to improve the compressive stability of the body component 10, enabling the structure to withstand greater loads.

[0053] Furthermore, the number of second pipe beams 210 includes two, with one second pipe beam 210 provided on each second side plate 240. Specifically, two second pipe beams 210 are provided on the second vehicle body pillar 200, wherein each of the two second side plates 240 is connected to one second pipe beam 210. The two second pipe beams 210 can be symmetrically connected on the two second side plates 240.

[0054] In summary, the first tube beam 340 is fixed to the side beam groove 330 on the side beam connecting plate 300. The two cooperate to bear the main pressure on the vehicle roof. Reducing the thickness of the side beam connecting plate 300 can reduce the weight of the vehicle body component 10 while improving vehicle strength, thus meeting the requirements for vehicle lightweighting. Furthermore, the first body pillar 100 and the second body pillar 200 are fixed on the side away from the side beam connecting plate 300 on the vehicle roof. The force transmission path can reach the body pillar through the side beam connecting plate 300, further enhancing the strength of the vehicle body component 10 and avoiding poor force transmission path during vehicle collision, thereby avoiding the risk of brittle fracture.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
