Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and more particularly to vehicles. Background Technology

[0002] Vehicles include a body frame, which plays an important role in improving the overall rigidity and strength of the vehicle. However, the body frame has a high production cost. Therefore, how to improve the overall rigidity and strength of the vehicle and reduce the production cost of the body frame has become one of the research issues in the industry. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a vehicle that not only improves the overall rigidity and strength of the vehicle but also reduces the production cost of the vehicle body frame.

[0004] The embodiments of this application are implemented through the following technical solutions.

[0005] The first aspect of this application provides a vehicle, the vehicle including a body frame, the body frame including: a frame beam body, at least a portion of the frame beam body forming an upper beam of the vehicle, the portion of the frame beam body forming at least the upper beam having a groove; a reinforcing structure including a reinforcing tube, the reinforcing tube at least partially filling the groove of the upper beam, the reinforcing tube being an integral rolled tube having a closed cross-section.

[0006] In the technical solution of this application, on the one hand, by filling the groove of the upper beam with a reinforcing tube, the strength of the upper beam can be improved, thereby enhancing the vehicle's resistance to deformation and reducing the degree of vehicle damage. On the other hand, the reinforcing tube is an integral roll-formed tube with a closed cross-section. The strength of a reinforcing tube with a closed cross-section is higher, which can further improve the strength of the upper beam. The integral roll-formed tube is simple to manufacture, requires fewer molds, and has a simple mold structure and high versatility, which simplifies the production process of the reinforcing tube, improves production efficiency, reduces the production cost of the reinforcing tube, and thus reduces the production cost of the vehicle body frame. Furthermore, as an integral roll-formed tube, the reinforcing tube can achieve complex curved shapes, meeting the structural design requirements of the vehicle body frame.

[0007] In some embodiments, the reinforcing tube includes a tube body with an internal cavity and at least one reinforcing rib filling the tube body.

[0008] The reinforced tube has a cavity inside, which reduces the weight of the material. Furthermore, in the event of an impact, the cavity deforms to absorb the impact force, thus reducing its destructive potential. Additionally, reinforcing ribs inside the tube provide extra structural support, enhancing its rigidity and strength, further improving the vehicle frame's resistance to deformation, reducing deformation, and minimizing intrusion into the vehicle's interior.

[0009] In some embodiments, in a cross-section perpendicular to the extension direction of the tube, the reinforcing rib extends along a first direction, and its opposite ends are respectively connected to the inner wall of the tube.

[0010] Therefore, the impact force acting on the reinforced tube can be transmitted through the tube wall to the internal reinforcing ribs, allowing the reinforcing ribs to absorb part of the impact force, thereby further improving the stiffness and strength of the reinforced tube.

[0011] In some embodiments, the first direction intersects the width direction of the vehicle.

[0012] The two ends of the reinforcing rib along the first direction are connected to the inner wall of the tube, that is, the cross section of the reinforcing rib extends along the first direction. Since the first direction intersects the width direction of the vehicle, the extension direction of the cross section of the reinforcing rib intersects the width direction of the vehicle. This reduces the probability of the reinforcing rib deforming due to impact forces along the front-rear direction and the vertical direction of the vehicle, thereby further enhancing the rigidity and strength of the reinforcing tube, further improving the deformation resistance of the vehicle body frame, reducing its deformation amount, and reducing the amount of intrusion into the vehicle interior.

[0013] In some embodiments, the reinforcing tube includes a starting section, a plurality of intermediate sections and a closing section that are connected in sequence and bent relative to each other, at least one of the intermediate sections is configured as a reinforcing rib, and the starting section and the closing section abut against the two sides of the reinforcing rib along the thickness direction of the reinforcing rib, respectively.

[0014] Since the starting section abuts against one side of the reinforcing rib along the thickness direction of the reinforcing rib, and the ending section abuts against the other side of the reinforcing rib along the thickness direction of the reinforcing rib, the reinforcing tube can be easily formed into an integral roll-formed tube with a closed cross-section, which is simple to manufacture.

[0015] In some embodiments, the starting segment and the ending segment abut against the opposite ends of the reinforcing rib along the first direction.

[0016] Therefore, the reinforcing tube can be easily formed into a one-piece roll-formed tube with a closed cross-section, simplifying manufacturing. Furthermore, it saves materials, reduces costs, and increases the lightweight nature of the reinforcing tube, thereby improving the lightweight nature of the vehicle body frame.

[0017] In some embodiments, the plurality of intermediate segments include a first intermediate segment, a second intermediate segment, a third intermediate segment, a reinforcing rib, a fourth intermediate segment, a fifth intermediate segment, and a sixth intermediate segment that are sequentially connected and relatively bent. The first intermediate segment is connected to the starting segment, and the sixth intermediate segment is connected to the ending segment. The starting segment, the first intermediate segment, the second intermediate segment, the third intermediate segment, and the reinforcing rib surround to form a first cavity. The second intermediate segment is closer to the inner side of the vehicle than the reinforcing rib, and the first intermediate segment is closer to the lower side of the vehicle than the third intermediate segment. The reinforcing rib, the fourth intermediate segment, the fifth intermediate segment, and the sixth intermediate segment surround to form a second cavity. The fifth intermediate segment is closer to the outer side of the vehicle than the reinforcing rib, and the fourth intermediate segment is closer to the lower side of the vehicle than the sixth intermediate segment.

[0018] Therefore, the reinforcing tube can be easily formed into an integral roll-formed tube with two closed cross sections, simplifying manufacturing. Moreover, since the reinforcing tube includes a first cavity and a second cavity, it can optimize the transmission path of impact force when a vehicle is impacted. The two cavities can deform together to absorb the impact force generated during the collision, thereby reducing the destructive power of the impact force and improving the bending resistance of the reinforcing tube.

[0019] In some embodiments, the dimensions of the reinforcing rib along the first direction are in the range of 32 mm to 40 mm.

[0020] The dimensions of the reinforcing rib along the first direction are in the range of 32mm to 40mm, which can take into account both the need to avoid the mold (roller), the need for lightweighting of the reinforcing tube, and the need for strength.

[0021] In some embodiments, within the same projection plane projected along the thickness direction of the reinforcing rib, the overlapping portion of the projection of the starting segment and the projection of the reinforcing rib along the first direction is in the range of 5mm to 8mm, and / or within the same projection plane projected along the thickness direction of the reinforcing rib, the overlapping portion of the projection of the ending segment and the projection of the reinforcing rib along the first direction is in the range of 5mm to 8mm.

[0022] Since the overlap between the projections of the starting segment and the reinforcing rib along the first direction is within the range of 5mm to 8mm, the starting segment and the reinforcing rib can be easily connected after contact, and material can be saved. Similarly, since the overlap between the projections of the ending segment and the reinforcing rib along the first direction is within the range of 5mm to 8mm, the ending segment and the reinforcing rib can be easily connected after contact, and material can be saved.

[0023] In some embodiments, the reinforcing tube is made of steel with a tensile strength in the range of 1180 MPa to 1700 MPa.

[0024] Therefore, it can not only improve the performance of the reinforcing tube, increase its strength and rigidity, and thus improve the strength and rigidity of the vehicle frame, but also facilitate the reduction of the tube wall thickness, thereby reducing the weight of the reinforcing tube, increasing its lightweighting, and thus increasing the lightweighting of the vehicle frame.

[0025] In some embodiments, the wall thickness of the reinforcing tube is in the range of 1.5 mm to 2 mm.

[0026] This not only greatly improves the strength of the reinforcing tube, but also avoids affecting the lightweight and miniaturization of the vehicle frame due to excessive thickness.

[0027] In some embodiments, the maximum dimension of the first cavity along the thickness direction of the reinforcing rib is in the range of 20 mm to 40 mm; the maximum dimension of the second cavity along the thickness direction of the reinforcing rib is in the range of 20 mm to 40 mm.

[0028] This allows for the simultaneous consideration of the requirements for lightweighting, miniaturization, and strength of the clearance mold (roller) and reinforcing tube.

[0029] In some embodiments, the frame beam body includes a plurality of connected outer plates, the frame beam body has a plurality of bends at the location where the groove is formed, and at least two bends are formed by different outer plates.

[0030] Since the main body of the frame beam includes multiple connected outer plates, and at least two bends are formed by different outer plates, when connecting the reinforcing tube to the main body of the frame beam, the reinforcing tube can be connected to the outer plates while the multiple outer plates are separated. This increases the operating space, reduces the assembly difficulty of the vehicle frame, and makes it easier to reduce the space between the reinforcing tube and the outer plates. It is possible to assemble the main body of the frame beam and the reinforcing tube while reducing the internal cavity size. Thus, while meeting the strength and rigidity requirements of the vehicle, the impact of the vehicle frame on the driver's vision can be reduced.

[0031] In some embodiments, the plurality of outer panels include a first outer panel having a first bend and a second outer panel having a second bend, wherein a portion of the first outer panel overlaps and is bonded to each other.

[0032] Thus, the first and second outer plates can be bonded together to form the main body of the frame beam. The structure is simple and avoids weld marks or metal deformation during drying that could affect the flatness or aesthetics of the main frame beam. Furthermore, the main frame beam includes a first outer plate with a first bend and a second outer plate with a second bend. This allows the main frame beam to be disassembled, enabling separate connections between the first and second outer plates to the reinforcing tubes, and between the first and second outer plates themselves. This reduces the probability of interference during assembly of the main frame beam and the reinforcing tubes, and allows the reinforcing tubes to occupy the majority of the cavity area, improving the space utilization of the cavity. Additionally, since a portion of the first and second outer plates overlaps, bonding and connecting the first and second outer plates is convenient, which helps improve the strength and rigidity of the vehicle body frame, thereby enhancing the overall strength and rigidity of the vehicle.

[0033] In some embodiments, the first outer panel includes a first segment and a second segment forming a first bend, and the second outer panel includes a third segment and a fourth segment forming a second bend, wherein the first outer panel and the second outer panel are connected such that the first segment is closer to the inside of the vehicle than the third segment.

[0034] Therefore, a groove can be formed by the first outer plate and the second outer plate, which has a simple structure and is easy to assemble, and is convenient for bonding and assembly with the reinforcing tube.

[0035] In some embodiments, the vehicle frame also includes an interior trim panel connected to the frame beam body and / or reinforcing tube, the interior trim panel covering at least the recess from the inside of the vehicle frame.

[0036] In this way, the reinforcing tube is enclosed in the cavity formed by the interior panel and the upper side beam. This not only helps to improve the overall structural strength and rigidity of the upper side beam, the reinforcing tube, and the part of the body frame that covers the groove of the upper side beam, but also, due to the covering of the interior panel, the structure inside the groove is not directly exposed to the driver / passenger's view, which helps to improve the aesthetics of the body frame.

[0037] In some embodiments, at least a portion of the frame beam body also constitutes the A-pillar, B-pillar, C-pillar and sill beam of the vehicle, with the A-pillar, B-pillar and C-pillar all connected between the sill beam and the upper beam, and the reinforcing tube extending from the A-pillar to at least the C-pillar.

[0038] In this way, the reinforcing tube runs through the connection point between the A-pillar and the C-pillar and the upper side beam, forming a continuous top force transmission path, effectively dispersing the impact force borne by the A-pillar to the C-pillar area during a frontal collision, reducing the risk of deformation of the passenger compartment.

[0039] In some embodiments, the vehicle further includes a chassis, a body frame mounted on the chassis and together forming a passenger compartment, the body frame including a body pillar assembly, and a reinforcing structure including reinforcing columns, a portion of the frame beam body and the reinforcing columns together forming at least a portion of the body pillar assembly.

[0040] This can improve the strength and rigidity of the vehicle body pillar assembly.

[0041] In some embodiments, the vehicle also includes a battery unit mounted on the chassis.

[0042] Reducing the space occupied by the battery pack in the passenger compartment and trunk allows for more spacious seating and storage. Furthermore, mounting the battery pack on the chassis reduces the direct impact on occupants during a collision. Additionally, centralized chassis mounting facilitates maintenance and replacement, reducing the complexity of routine upkeep.

[0043] In some embodiments, the housing of the battery device forms at least a portion of the floor of the passenger compartment.

[0044] By integrating the battery pack into the passenger compartment floor, additional brackets and connectors can be reduced, which helps to reduce the overall vehicle weight and allows for more efficient use of the vehicle's interior space.

[0045] In some embodiments, the vehicle frame is detachably attached to the top of the chassis.

[0046] This design allows for the separation and decoupling of the body frame and chassis, enabling the body frame to be replaced as needed, shortening the development cycle and reducing costs. In other words, it also improves the integration of the chassis, making it adaptable to various vehicle models. Attached Figure Description

[0068] The embodiments of this application will now be described in detail.

[0069] Vehicles include a body frame, which plays an important role in improving the overall rigidity and strength of the vehicle. However, the body frame has a high production cost. Therefore, how to improve the overall rigidity and strength of the vehicle and reduce the production cost of the body frame has become one of the research issues in the industry.

[0070] In related technologies, vehicle body frames are typically formed using cold stamping, thermoforming, or hot air expansion processes. These processes suffer from technical problems such as complex mold structures, high mold costs, complex production processes, and high overall costs. Research has shown that reinforcing tubes can be added. These reinforcing tubes are integral roll-formed tubes with a closed cross-section. This not only improves the strength of the upper beam but also simplifies the manufacturing process of the integral roll-formed tube, requiring fewer molds, thus simplifying the production process, improving production efficiency, and reducing the production cost of the reinforcing tubes.

[0071] Based on this design concept, this application provides a vehicle, the vehicle including a body frame, the body frame including: a frame beam body, at least a portion of the frame beam body forming the upper beam of the vehicle, the portion of the frame beam body forming the upper beam having a groove; a reinforcing tube, at least partially filling the groove of the upper beam, the reinforcing tube being an integral rolled tube with a closed cross-section.

[0072] In the technical solution of this application, on the one hand, by filling the groove of the upper beam with a reinforcing tube, the strength of the upper beam can be improved, thereby enhancing the vehicle's resistance to deformation and reducing the degree of vehicle damage. On the other hand, the reinforcing tube is an integral roll-formed tube with a closed cross-section. The strength of a reinforcing tube with a closed cross-section is higher, which can further improve the strength of the upper beam. The integral roll-formed tube is simple to manufacture, requires fewer molds, and has a simple mold structure and high versatility, which simplifies the production process of the reinforcing tube, improves production efficiency, reduces the production cost of the reinforcing tube, and thus reduces the production cost of the vehicle body frame. Furthermore, as an integral roll-formed tube, the reinforcing tube can achieve complex curved shapes, meeting the structural design requirements of the vehicle body frame.

[0073] In the following embodiments, for ease of explanation, the description is provided in conjunction with the accompanying drawings.

[0074] Figure 1 This is an exploded perspective view of a vehicle 1000 according to one or more embodiments.

[0075] Vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended vehicles, etc. This application's embodiments do not impose special limitations on the aforementioned vehicles. Figure 1 As shown, the vehicle 1000 includes a chassis 100 and a body frame 200 disposed above the chassis 100. The body frame 200 and the chassis 100 together enclose the passenger compartment of the vehicle 1000.

[0076] For example, the body frame 200 and the chassis 100 are welded together.

[0077] In some embodiments of this application, the chassis 100 and the body frame 200 are detachably connected.

[0078] When the chassis 100 adopts a skateboard chassis integrating the three-electric system, the body frame 200 can be connected to the skateboard chassis in a detachable manner. For example, the detachable connection can be achieved by using multiple circumferential bolts. The following description uses the cooperation between the body frame and the skateboard chassis as an example.

[0079] This configuration allows for the separation and decoupling of the body frame 200 and the chassis 100, enabling the body frame 200 to be replaced as needed, shortening the development cycle and reducing costs. In other words, it also improves the integration of the chassis 100, making it adaptable to various vehicle models.

[0080] In some embodiments of this application, the vehicle frame 200 and the chassis 100 together enclose the passenger compartment 20 of the vehicle 1000, and the vehicle 1000 includes a battery device, the housing of which forms the floor of the passenger compartment.

[0081] By integrating the battery pack into the passenger compartment floor, additional supports and connectors can be reduced, which helps to reduce the overall vehicle weight and allows for more efficient use of the vehicle's interior space.

[0082] Figure 2 This is an exploded perspective view of a vehicle 1000 (excluding chassis 100) according to one or more embodiments.

[0083] like Figure 2 As shown, vehicle 1000 typically includes a load-bearing structure and an exterior structure. The load-bearing structure includes structures such as A-pillar 201, B-pillar 202, C-pillar 203, upper side beam 204, sill beam 205, upper crossbeam 206, and bumper 207. The exterior structure typically includes structures such as hood 208 and door 209.

[0084] Below, refer to Figures 3 to 10 Some embodiments of this application will be described in detail.

[0085] In some embodiments of this application, for ease of explanation, the inward and outward directions, left and right directions, front and rear directions, and up and down directions of the vehicle are defined. Sometimes, the left and right direction is referred to as the "width direction of the vehicle," the front and rear direction as the "length direction of the vehicle," and the up and down direction as the "height direction of the vehicle." In the accompanying drawings, the direction of arrow X is the "length direction of the vehicle," the direction of arrow Y is the "width direction of the vehicle," and the direction of arrow Z is the "height direction of the vehicle." The length direction X, width direction Y, and height direction Z of the vehicle intersect each other, and further, they are perpendicular to each other. In addition, sometimes the side facing the passenger compartment 20 is referred to as the inner side of the vehicle, and the side facing away from the passenger compartment 20 and towards the outside of the vehicle is referred to as the outer side of the vehicle.

[0086] In some embodiments, the direction in which the front and rear of the vehicle are located is the length direction of the vehicle, and the direction in which the roof and bottom of the vehicle are located is the height direction of the vehicle.

[0087] The first aspect of this application provides a vehicle 1000, such as Figures 1 to 10 As shown, the vehicle 1000 includes a body frame 200, which includes a frame beam body 2 and a reinforcing structure 10: at least a portion of the frame beam body 2 constitutes the upper beam 204 of the vehicle 1000, and the portion of the frame beam body 2 that constitutes the upper beam 204 has a groove; the reinforcing structure 10 includes a reinforcing tube 1, at least a portion of the reinforcing tube 1 fills the groove of the upper beam 204, and the reinforcing tube 1 is an integral rolled tube with a closed cross-section.

[0088] For example, such as Figure 3, Figure 9 and Figure 10 As shown, the frame beam body 2 has a first side and a second side facing away from each other. The first side faces the inside of the vehicle frame 200, and the second side faces the outside of the vehicle frame 200. A groove is formed on the first side of the frame beam body 2, that is, the opening of the groove faces the inside of the vehicle frame 200. The reinforcing tube 1 is provided on the first side, disposed in the groove, and connected to the frame beam body 2.

[0089] The groove can enhance strength and serve as an energy absorption zone, effectively absorbing and dispersing impact energy. In addition, the groove provides installation space for the reinforcing tube 1.

[0090] For example, the reinforcing tube 1 is bonded to the groove of the frame beam body 2 by structural adhesive.

[0091] For example, the reinforcing tube 1 may be partially or entirely located within the groove.

[0092] For example, such as Figures 5 to 8 As shown, the reinforcing tube 1 is an integral roll-formed tube with a closed cross-section. That is, the cross-section of the reinforcing tube 1 is closed, and it is integrally formed by roll forming.

[0093] Optionally, the outer contour of the reinforcing tube 1, which has a closed cross-section, can be a regular or irregular shape such as a quadrilateral, a circle, or a polygon.

[0094] One-piece roll-formed tube is a type of metal tube manufactured through a roll forming process. It uses continuous roll forming technology to directly form tubes from metal sheets.

[0095] In some embodiments, a portion of the frame beam body 2 and the reinforcing tube 1 constitute a portion of the upper beam assembly.

[0096] In the technical solution of this application, on the one hand, by using the reinforcing tube 1 to at least fill the groove of the upper beam 204, the strength of the upper beam 204 can be improved, thereby increasing the vehicle 1000's resistance to deformation and reducing the degree of damage to the vehicle 1000. On the other hand, the reinforcing tube 1 is an integral roll-formed tube with a closed cross-section. The reinforcing tube 1 with a closed cross-section has higher strength, which can further improve the strength of the upper beam 204. The integral roll-formed tube 1 is simple to manufacture, requires fewer molds, simplifies the production process of the reinforcing tube 1, improves production efficiency, reduces the production cost of the reinforcing tube 1, and thus reduces the production cost of the vehicle body frame 200. Furthermore, the reinforcing tube 1 is an integral roll-formed tube, which can realize complex curved shapes and meet the structural design requirements of the vehicle body frame 200.

[0097] In some embodiments, such as Figure 6 , Figure 8 or Figure 10As shown, the reinforcing tube 1 includes a tube body with a cavity 14 formed therein and at least one reinforcing rib 127 filled in the tube body.

[0098] Exemplarily, as Figure 6 , Figure 8 or Figure 10 shown, there is one reinforcing rib 127 provided in the cavity 14 of the tube body.

[0099] Exemplarily, there are two or more reinforcing ribs 127 provided in the cavity 14 of the tube body, and the two or more reinforcing ribs 127 can be arranged substantially parallel or non - parallel.

[0100] Exemplarily, the shape of the plate can be made into a "day" - shaped, "eye" - shaped or other shapes through a rolling process.

[0101] Exemplarily, the plate is integrally formed into a tube body with reinforcing ribs 127 through a rolling process. The outermost circle of the reinforcing tube 1 is the tube body, and at least part of the structure inside the tube body is the reinforcing rib 127.

[0102] A cavity 14 is formed in the reinforcing tube 1, which can reduce the weight of the material. Moreover, when the vehicle 1000 is impacted, the cavity 14 will deform to absorb the impact force generated during the collision, thereby reducing the destructive ability of the impact force. In addition, there are reinforcing ribs 127 provided in the tube body. Thus, it can provide additional structural support for the tube body, thereby enhancing the rigidity and strength of the reinforcing tube 1, further improving the anti - deformation ability of the vehicle body frame 200, reducing its deformation amount, and reducing the intrusion amount into the vehicle 1000.

[0103] Those skilled in the art should understand that the embodiments of the present application do not specifically limit the number of the reinforcing ribs 127, which can be set according to the performance requirements of the vehicle body frame 200.

[0104] Those skilled in the art should also understand that there may be no reinforcing ribs 127 provided in the cavity 14 of the tube body.

[0105] In some embodiments, as Figure 6 , Figure 8 or Figure 10 shown, in a cross - section perpendicular to the extending direction of the tube body, the reinforcing rib 127 extends along the first direction M, and its opposite ends are respectively connected to the inner wall of the tube body.

[0106] It can be understood that the opposite ends of the reinforcing rib 127 along the first direction M are respectively connected to the inner wall of the tube body.

[0107] Exemplarily, in the cross - section of the tube body, the reinforcing rib 127 can extend along the width direction Y of the vehicle or in a direction intersecting with the width direction Y of the vehicle.

[0108] Therefore, the impact force acting on the reinforcing tube 1 can be transmitted through the tube wall to the internal reinforcing rib 127, so that the reinforcing rib 127 can absorb part of the impact force, thereby helping to further improve the stiffness and strength of the reinforcing tube 1.

[0109] In some embodiments, such as Figure 6 , Figure 8 or Figure 10 As shown, the first direction M intersects the width direction Y of the vehicle. That is, the extension direction of the reinforcing rib 127 in the cross-section of the tube intersects the width direction Y of the vehicle.

[0110] For example, the reinforcing rib 127 may extend along the height direction Z of the vehicle, or it may extend along a direction that intersects both the height direction Z and the width direction Y of the vehicle.

[0111] The two ends of the reinforcing rib 127 along the first direction M are respectively connected to the inner wall of the tube. That is, the cross section of the reinforcing rib 127 extends along the first direction M. Since the first direction M intersects the width direction Y of the vehicle, the extension direction of the cross section of the reinforcing rib 127 intersects the width direction Y of the vehicle. This reduces the probability of the reinforcing rib 127 deforming due to impact forces along the front-rear and vertical directions of the vehicle, thereby further enhancing the rigidity and strength of the reinforcing tube 1, further improving the deformation resistance of the vehicle frame 200, reducing its deformation amount, and reducing the amount of intrusion into the interior of the vehicle 1000.

[0112] In some embodiments, such as Figure 8 As shown, the reinforcing tube 1 includes a starting section 11, a plurality of intermediate sections 12 and a closing section 13 that are connected in sequence and bent relative to each other. At least one of the intermediate sections 12 is configured as a reinforcing rib 127. The starting section 11 and the closing section 13 respectively abut against the two sides of the reinforcing rib along the thickness direction N of the reinforcing rib.

[0113] For example, the starting segment 11 abuts against one side of the reinforcing rib 127 along the thickness direction N, and the ending segment 13 abuts against the other side of the reinforcing rib 127 along the thickness direction N. The thickness direction N of the reinforcing rib intersects the first direction M.

[0114] Optionally, one, two, three, or more of all the intermediate segments 12 may be configured as reinforcing ribs 127. In a specific embodiment, such as Figure 8 As shown, one of the intermediate segments 12 is configured as a reinforcing rib 127.

[0115] For example, such as Figure 8 As shown, the starting segment 11 and the ending segment 13 abut against both sides of the reinforcing rib 127 along the thickness direction N of the reinforcing rib.

[0116] For example, such as Figure 8 As shown, the starting segment 11 extends along the first direction M, and one side of the starting segment 11 along the thickness direction N of the reinforcing rib abuts against one side of the reinforcing rib 127 along the thickness direction N of the reinforcing rib. Furthermore, the starting segment 11 and the reinforcing rib 127 can be bonded or welded, for example, by laser welding.

[0117] For example, such as Figure 8 As shown, the termination section 13 extends along the first direction M, and one side of the termination section 13 along the thickness direction N of the reinforcing rib abuts against one side of the reinforcing rib 127 along the thickness direction N of the reinforcing rib. Furthermore, the termination section 13 and the reinforcing rib 127 can be bonded or welded, for example, by laser welding.

[0118] For example, the starting segment 11, multiple intermediate segments 12 and the ending segment 13 are integrally formed.

[0119] Since the starting section 11 abuts against one side of the reinforcing rib 127 along the thickness direction N, and the ending section 13 abuts against the other side of the reinforcing rib 127 along the thickness direction N, the reinforcing tube 1 can be easily formed into an integral roll-formed tube with a closed cross-section, simplifying manufacturing. It is understood that, among the plurality of intermediate sections 12, the intermediate sections 12 other than the one serving as the reinforcing rib 127 constitute at least a portion of the tube body. The starting section 11 may also abut against the outer surface of the tube body. The ending section 13 may also abut against the outer surface of the tube body.

[0120] In some embodiments, such as Figure 8 As shown, the starting segment 11 and the ending segment 13 abut against the opposite ends of the reinforcing rib 127 along the first direction M.

[0121] For example, the starting segment 11 abuts against one end of the reinforcing rib 127 along the first direction M, and the ending segment 13 abuts against the other end of the reinforcing rib 127 along the first direction M.

[0122] For example, the starting segment 11 abuts against one side of the reinforcing rib 127 along the thickness direction N of the reinforcing rib, and abuts against one end of the reinforcing rib 127 along the first direction M; the ending segment 13 abuts against the other side of the reinforcing rib 127 along the thickness direction N of the reinforcing rib, and abuts against the other end of the reinforcing rib 127 along the first direction M.

[0123] Therefore, the reinforcing tube 1 can be easily formed into an integral roll-formed tube with a closed cross-section, simplifying manufacturing. Furthermore, it saves materials, reduces costs, and increases the lightweighting of the reinforcing tube 1, thereby improving the lightweighting of the vehicle body frame 200.

[0124] Understandably, along the first direction M, the starting segment 11 can abut against both ends of the reinforcing rib 127; for example, along the first direction M, the starting segment 11 extends from one end of the reinforcing rib 127 to the other end. Similarly, along the first direction M, the ending segment 13 can abut against both ends of the reinforcing rib 127; for example, along the first direction M, the ending segment 13 extends from one end of the reinforcing rib 127 to the other end.

[0125] In some embodiments, such as Figure 8 and Figure 10 As shown, the plurality of intermediate segments 12 include a first intermediate segment 121, a second intermediate segment 122, a third intermediate segment 123, a reinforcing rib 127, a fourth intermediate segment 124, a fifth intermediate segment 125, and a sixth intermediate segment 126 that are connected in sequence and bent relative to each other. The first intermediate segment 121 is connected to the starting segment 11, and the sixth intermediate segment 126 is connected to the ending segment 13. The starting segment 11, the first intermediate segment 121, the second intermediate segment 122, the third intermediate segment 123, and the reinforcing rib 127 surround to form the first intermediate segment 126. Cavity 141, second intermediate section 122 is closer to the inner side of vehicle 1000 than reinforcing rib 127, first intermediate section 121 is closer to the lower side of vehicle 1000 than third intermediate section 123, reinforcing rib 127, fourth intermediate section 124, fifth intermediate section 125 and sixth intermediate section 126 surround to form second cavity 142, fifth intermediate section 125 is closer to the outer side of vehicle 1000 than reinforcing rib 127, fourth intermediate section 124 is closer to the lower side of vehicle 1000 than sixth intermediate section 126.

[0126] For example, such as Figure 10 As shown, along the width direction Y of the vehicle 1000, at least a portion of the first cavity 141 is located inside the second cavity 142.

[0127] For example, such as Figure 10 As shown, along the connection direction of the multiple intermediate segments 12, the included angle between two adjacent intermediate segments 12 can be acute, obtuse, or approximately right.

[0128] For example, such as Figure 10 As shown, in the cross-section of the reinforcing tube 1, along the length direction X of the vehicle, the sixth intermediate section 126 is formed by connecting the relatively bent first sub-intermediate section and the second sub-intermediate section. The reinforcing bend formed by the first sub-intermediate section and the second sub-intermediate section is away from the lower protrusion of the vehicle 1000, thereby enhancing the strength and rigidity of the sixth intermediate section 126 and improving the collision resistance performance of the vehicle 1000.

[0129] Therefore, the reinforcing tube 1 can be easily formed into an integral roll-formed tube with two closed cross sections, simplifying manufacturing. Moreover, since the reinforcing tube 1 includes a first cavity 141 and a second cavity 142, it can optimize the transmission path of the impact force when the vehicle 1000 is impacted. The two cavities 14 can deform together to absorb the impact force generated during the collision, thereby reducing the destructive power of the impact force and improving the bending resistance of the reinforcing tube 1.

[0130] In some embodiments, such as Figure 8 As shown, the dimension D1 of the reinforcing rib 127 along the first direction M is in the range of 32mm to 40mm. The dimension D1 of the reinforcing rib 127 along the first direction M refers to the two ends of the reinforcing rib 127 along the first direction M (e.g., ...). Figure 8 The maximum distance between the left and right ends shown.

[0131] Optionally, the dimension D1 of the reinforcing rib 127 along the first direction M can be 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm or 40mm, etc., or any value between the two values ​​mentioned above.

[0132] The dimension of the reinforcing rib 127 along the first direction M is in the range of 32mm to 40mm, which can take into account both the need to avoid the mold (roller), the need for lightweighting of the reinforcing tube 1, and the need for strength.

[0133] In some embodiments, within the same projection plane projected along the thickness direction N of the reinforcing rib, the overlapping portion of the projection of the starting segment 11 and the projection of the reinforcing rib 127 along the first direction M has a dimension D3 in the range of 5mm to 8mm, and / or within the same projection plane projected along the thickness direction N of the reinforcing rib, the overlapping portion of the projection of the ending segment 13 and the projection of the reinforcing rib 127 along the first direction M has a dimension D4 in the range of 5mm to 8mm.

[0134] Optionally, within the same projection plane projected along the thickness direction N of the reinforcing rib, the overlapping portion of the projection of the starting segment 11 and the projection of the reinforcing rib 127 along the first direction M can have a size D3 of 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc., or any value between the two values ​​mentioned above.

[0135] Optionally, within the same projection plane projected along the thickness direction N of the reinforcing rib, the overlapping portion of the projection of the tail section 13 and the projection of the reinforcing rib 127 along the first direction M can have a size D4 of 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc., or any value between the two values ​​mentioned above.

[0136] Since the overlap between the projection of the starting segment 11 and the projection of the reinforcing rib 127 along the first direction M is within the range of 5mm to 8mm, the starting segment 11 and the reinforcing rib 127 can be easily connected after contact, and materials can be saved. Similarly, since the overlap between the projection of the ending segment 13 and the projection of the reinforcing rib 127 along the first direction M is within the range of 5mm to 8mm, the ending segment 13 and the reinforcing rib 127 can be easily connected after contact, and materials can be saved.

[0137] In some embodiments, the reinforcing tube 1 is made of steel with a tensile strength in the range of 1180 MPa to 1700 MPa.

[0138] Optionally, the reinforcing tube 1 is made of steel, and the strength of the steel can be 1180MPa, 1200MPa, 1250MPa, 1300MPa, 1350MPa, 1400MPa, 1450MPa, 1500MPa, 1550MPa, 1600MPa, 1650MPa, 1700MPa, etc., or any value between the two values ​​mentioned above.

[0139] For example, the reinforcing tube 1 is made of high-strength steel, such as martensitic steel or special alloy steel.

[0140] Therefore, it can not only improve the performance of the reinforcing tube 1, increase the strength and rigidity of the reinforcing tube 1, and thus increase the strength and rigidity of the body frame 200, but also facilitate the reduction of the tube wall thickness, thereby reducing the weight of the reinforcing tube 1, increasing the lightweighting of the reinforcing tube 1, and thus increasing the lightweighting of the body frame 200.

[0141] In some embodiments, such as Figure 8 As shown, the wall thickness D2 of the reinforcing tube 1 is in the range of 1.5mm to 2mm.

[0142] For example, the reinforcing tube 1 includes a tube body and a reinforcing rib 127. The thickness D2 of the tube body wall is in the range of 1.5 mm to 2 mm. The thickness D2 of the tube body wall refers to the distance from the inner surface to the outer surface of the tube wall.

[0143] For example, the thickness D2 of the pipe wall can remain constant or vary.

[0144] For example, the reinforcing tube 1 includes a tube body and a reinforcing rib 127. The thickness D2 of the reinforcing rib 127 is in the range of 1.5 mm to 2 mm. The thickness of the reinforcing rib 127 refers to the distance between one surface of the reinforcing rib and the other surface along the thickness direction N of the reinforcing rib.

[0145] For example, the thickness D2 of the reinforcing rib 127 may remain constant or vary.

[0146] For example, the thickness of the reinforcing rib 127 may be the same as or different from the thickness of the pipe wall.

[0147] Optionally, the wall thickness D2 of the reinforcing tube 1 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm or 2mm, etc., or any value between the two values ​​mentioned above.

[0148] This not only greatly improves the strength of the reinforcing tube 1, but also avoids affecting the lightweight and miniaturization of the body frame 200 due to excessive thickness.

[0149] In some embodiments, the maximum dimension D5 of the first cavity 141 along the thickness direction N of the reinforcing rib is in the range of 20 mm to 40 mm; the maximum dimension D6 of the second cavity 142 along the thickness direction N of the reinforcing rib is in the range of 20 mm to 40 mm.

[0150] For example, such as Figure 8 As shown, along the thickness direction N of the reinforcing rib, the maximum dimension D5 of the first cavity 141 refers to the maximum distance from the inner surface of the second intermediate section 122 to the surface of the reinforcing rib 127 facing the second intermediate section 122.

[0151] For example, the maximum dimension D5 of the first cavity 141 along the thickness direction N of the reinforcing rib can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm or 40mm, etc., or any value between the above two values.

[0152] For example, such as Figure 8 As shown, along the thickness direction N of the reinforcing rib 127, the maximum dimension D6 of the second cavity 142 refers to the maximum distance from the inner surface of the fifth intermediate section 125 to the surface of the reinforcing rib 127 facing the fifth intermediate section 125.

[0153] For example, the maximum dimension D6 of the second cavity 142 along the thickness direction N of the reinforcing rib can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm or 40mm, etc., or any value between the above two values.

[0154] Therefore, it is possible to simultaneously meet the requirements of lightweighting, miniaturization, and strength of the clearance mold (roller) and reinforcing tube 1.

[0155] In some embodiments, such as Figure 9 and Figure 10 As shown, the frame beam body 2 includes multiple connected outer plates 22, and the frame beam body 2 has multiple bends at the locations where the grooves are formed, with at least two bends formed by different outer plates 22.

[0156] In some embodiments, such as Figure 10 As shown, the frame beam body 2 includes multiple interconnected outer plates 22. Optionally, from the cross-section of a certain beam member of the frame beam body 2, two, three, or four equal outer plates 22 may be connected to each other to form the frame beam body 2. The following explanation will take the case where two outer plates 22 (first outer plate 221 and second outer plate 222) are connected to each other to form the frame beam body 2 as an example.

[0157] In some embodiments, such as Figure 10 As shown, the frame beam body 2 has multiple bends at the locations where the grooves are formed; for example, there can be two, three, or four bends. When the cross-sectional shape of the groove is polygonal, more bends can be designed depending on the number of sides.

[0158] In some embodiments, at least two bends are formed by different outer plates 22. In one specific embodiment, such as Figure 10 As shown, there are two bends, each formed by bending two outer plates 22. Specifically, there is a bend at each end of the groove bottom, and the groove is formed by joining the first outer plate 221 and the second outer plate 222, which each has a bend. Alternatively, at the groove opening, the first outer plate 221 and the second outer plate 222 each have a bend, forming an interface that facilitates adhesion to the interior trim panel 3. Regarding the assembly method, an example is... Figure 10As shown, one of the outer panels 22 with a bend (first outer panel 221) can be connected to the reinforcing tube 1, and another outer panel 22 with a bend (second outer panel 222) can be connected to the side of the first outer panel 221 facing away from the reinforcing tube 1. The assembly of the outer panel 22 and the reinforcing tube 1 is then connected to the interior panel 3. Since the first outer panel 221 and the second outer panel 222 can be separated during assembly, there is ample operating space, reducing the possibility of interference between parts or between tools and parts during the assembly of the reinforcing tube 1 to the outer panel 22 and the interior panel 3. This reduces the assembly difficulty of the vehicle frame 200 and allows for easier reduction of the space between the reinforcing tube 1 and the outer panel 22, enabling the assembly of the frame beam body 2 and the reinforcing tube 1 while reducing the internal cavity size. Therefore, while meeting the strength and rigidity requirements of the vehicle 1000, the impact of the vehicle frame 200 on the driver's visibility can be reduced.

[0159] Since the frame beam body 2 includes multiple connected outer plates 22, and at least two bends are formed by different outer plates 22, when the reinforcing tube 1 is connected to the frame beam body 2, the reinforcing tube 1 can be connected to the outer plates 22 while the multiple outer plates 22 are separated. This increases the operating space, reduces the assembly difficulty of the vehicle body frame 200, and makes it easier to reduce the space between the reinforcing tube 1 and the outer plates 22. It can achieve the assembly of the frame beam body 2 and the reinforcing tube 1 while reducing the internal cavity size. Thus, while meeting the strength and rigidity requirements of the vehicle 1000, the impact of the vehicle body frame 200 on the driver's vision can be reduced.

[0160] In some embodiments, the plurality of outer panels 22 include a first outer panel 221 having a first bend and a second outer panel 222 having a second bend, wherein a portion of the first outer panel 221 overlaps with a portion of the second outer panel 222 and is bonded to each other.

[0161] The first outer plate 221 and the second outer plate 222 can each be an integral plate. The first outer plate 221 has at least one bend; the second outer plate 222 has at least one bend. The first outer plate 221 and the second outer plate 222 are joined together in a partially overlapping manner, and at least two of these bends form the corner of the groove.

[0162] In one specific embodiment, the first outer plate 221 is an integrally molded part, and the first outer plate 221 is molded to form the first bent part.

[0163] In one specific embodiment, the second outer plate 222 is an integrally molded part, and the second outer plate 222 is molded to form the second bent part.

[0164] In some embodiments, such as Figure 10 As shown, the first outer panel 221 and the second outer panel 222 have overlapping portions, which can be bonded together. The overlapping portions can be the parts of the first outer panel 221 and the second outer panel 222 that are close to each other along the vertical direction of the vehicle body. In the bonded state, the overlapping portions are located between the first bend and the second bend, forming the bottom of the groove.

[0165] In some embodiments, the first outer panel 221 and the second outer panel 222 are both fiber composite boards. Thus, the first outer panel 221 and the second outer panel 222 can be bonded with fast-curing adhesive, which is easy to operate and takes little time. Moreover, it is less likely to cause defects such as deformation after bonding and baking of metal parts.

[0166] Thus, the first outer plate 221 and the second outer plate 222 can be bonded together to form the frame beam body 2. The structure is simple and there are no weld marks or metal part drying deformations that would affect the flatness or aesthetics of the frame beam body 2. Furthermore, the frame beam body 2 includes a first outer plate 221 with a first bend and a second outer plate 222 with a second bend. This allows the frame beam body 2 to be disassembled, enabling the connection of the first outer plate 221 to the reinforcing tube 1 and the connection of the first outer plate 221 to the second outer plate 222 to each other while the first outer plate 221 and the second outer plate 222 are separated. This reduces the probability of interference during the assembly of the frame beam body 2 and the reinforcing tube 1, and allows the reinforcing tube 1 to occupy most of the groove area, improving the space utilization of the groove. In addition, since a portion of the first outer plate 221 overlaps with a portion of the second outer plate 222, the bonding connection of the first outer plate 221 and the second outer plate 222 is convenient, which helps to improve the strength and rigidity of the vehicle frame 200, thereby improving the overall strength and rigidity of the vehicle 1000.

[0167] In some embodiments, such as Figure 10 As shown, the reinforcing tube 1 is bonded to at least one of the frame beam body 2 and the interior panel 3.

[0168] In some embodiments, the first outer panel 221 includes a first segment 2211 and a second segment 2212 forming a first bend, and the second outer panel 222 includes a third segment 2221 and a fourth segment 2222 forming a second bend. The first outer panel 221 and the second outer panel 222 are connected such that the first segment 2211 is closer to the inside of the vehicle 1000 than the third segment 2221.

[0169] In some embodiments, such as Figure 10As shown, the first plate segment 2211 and the third plate segment 2221 are bonded together, and the reinforcing tube 1 is bonded to the side of the first plate segment 2211 away from the third plate segment 2221. The second plate segment 2212 is closer to the upper crossbeam 206 in the vehicle width direction than the reinforcing tube 1, and the fourth plate segment 2222 is farther away from the upper crossbeam 206 in the vehicle width direction than the reinforcing tube 1.

[0170] Therefore, a groove can be formed by the first outer plate 221 and the second outer plate 222, which has a simple structure and is easy to assemble, and is convenient for bonding and assembly with the reinforcing tube 1.

[0171] In some embodiments, the frame beam body 2 is bonded to the interior panel 3.

[0172] Thus, the frame beam body 2 and the interior panel 3 can form a sealed cavity 14, which improves the strength of the body frame 200, and the bonding connection method is convenient to operate.

[0173] In some embodiments, the frame beam body 2 is made of glass fiber reinforced composite material, and / or the interior panel 3 is made of glass fiber reinforced composite material.

[0174] Glass fiber reinforced composite materials have advantages such as lightweight, high strength, good corrosion resistance, design flexibility, and ease of processing. Therefore, the frame beam body 2 can further improve the lightweighting of the body frame 200 while meeting the strength and stiffness requirements of the body frame 200, thereby improving the lightweighting of the vehicle 1000, enhancing the appearance of the body, and also helping to improve production efficiency.

[0175] In some embodiments, the frame beam body 2 is made of glass fiber reinforced polypropylene composite material, and / or the interior panel 3 is made of glass fiber reinforced polypropylene composite material.

[0176] Glass fiber reinforced polypropylene composite material has high strength and rigidity, creep resistance and good dimensional stability, which can further improve the strength and rigidity of the frame beam body 2 and / or interior panel 3, thereby further improving the strength and rigidity of vehicle 1000, and making vehicle 1000 less prone to deformation even in high temperature environments.

[0177] In some embodiments, the glass fiber reinforced polypropylene composite material includes glass fiber and a thermoplastic resin matrix, wherein the weight parts of the glass fiber are greater than or equal to 60 and less than or equal to 80, the weight parts of the thermoplastic resin matrix are greater than or equal to 20 and less than or equal to 40, and the sum of the weight parts of the glass fiber and the weight parts of the thermoplastic resin matrix is ​​100.

[0178] The frame beam body 2 thus balances strength, rigidity, ease of processing, and aesthetic appearance.

[0179] In some embodiments, the glass fiber in the glass fiber reinforced polypropylene composite material has a weight percentage of 68% and 75%.

[0180] This allows for further optimization of the strength, stiffness, ease of processing, and aesthetic appearance of the main frame beam 2.

[0181] In some embodiments, the vehicle frame 200 further includes an interior panel 3, which is connected to the frame beam body 2 and / or the reinforcing tube 1, and the interior panel 3 covers at least the groove from the inside of the vehicle frame 200.

[0182] For example, such as Figure 9 As shown, the reinforcing tube 1 and the interior trim panel 3 are connected by fasteners, which include, but are not limited to, bolts, screws, rivets, etc.

[0183] Thus, the reinforcing tube 1 is enclosed within the space formed by the interior panel 3 and the upper beam 204. This not only helps to improve the overall structural strength and rigidity of the upper beam assembly, including the upper beam 204, the reinforcing tube 1, and the portion of the upper beam 204 covered by the interior panel 3, but also, due to the covering of the interior panel 3, the structure inside the groove is not directly exposed to the driver's / passenger's view, which helps to improve the aesthetics of the vehicle frame 200.

[0184] In some embodiments, at least a portion of the frame beam body 2 also constitutes the A-pillar 201, B-pillar 202, C-pillar 203 and sill beam 205 of the vehicle 1000. The A-pillar 201, B-pillar 202 and C-pillar 203 are all connected between the sill beam 205 and the upper beam 204, and the reinforcing tube 1 extends from the A-pillar 201 to at least the C-pillar 203.

[0185] Thus, the reinforcing tube 1 runs through the connection point between the A-pillar 201 and the C-pillar 203 and the upper beam 204, forming a continuous top force transmission path, effectively dispersing the impact force borne by the A-pillar 201 to the C-pillar 203 area during a frontal collision, reducing the risk of deformation of the passenger compartment.

[0186] In some embodiments, the vehicle 1000 further includes a chassis 100, a body frame 200 mounted on the chassis 100 and together forming a passenger compartment, the body frame 200 including a body pillar assembly, the reinforcing structure 10 further including a reinforcing column 4, a portion of the frame beam body 2 and the reinforcing column 4 together forming at least a portion of the body pillar assembly.

[0187] The vehicle body pillar assembly includes the A-pillar assembly, the B-pillar assembly, and the C-pillar assembly.

[0188] For example, such as Figure 1As shown, a reinforcing column 4 is provided in the groove of the A-pillar 201. The reinforcing column 4 and the frame beam body 2 together form at least part of the A-pillar assembly (also known as the A-pillar assembly).

[0189] For example, the reinforcing column 4 in the groove of column A 201 can be an integral rolled tube.

[0190] For example, such as Figure 1 and Figure 4 As shown, another reinforcing column 4 is provided in the groove of the B-pillar 202. The other reinforcing column and the frame beam body 2 together form at least part of the B-pillar assembly (also known as the B-pillar assembly).

[0191] For example, another reinforcing column within the groove of column B 202 can be an integral roll-formed tube.

[0192] For example, such as Figure 1 and Figure 4 As shown, a reinforcing column 4 is provided in the groove of the C-pillar 203. The reinforcing column and the frame beam body 2 together form at least part of the C-pillar 203.

[0193] For example, the additional reinforcing column within the groove of column C 203 can be an integral roll-formed tube.

[0194] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, one end of the reinforcing column 4 is connected to the reinforcing pipe 1 through the upper connector 61, and the other end of the reinforcing column 4 is connected to the sill beam 205 through the lower connector 62.

[0195] In this way, the connection between the reinforcing column 4, the reinforcing pipe 1, and the threshold beam 205 is achieved.

[0196] For example, the upper connector is connected to one end of the reinforcing column 4 by a plug-in connection, and the upper connector 61 is connected to the reinforcing tube 1 by bolts or other fasteners. The lower connector 62 is connected to the other end of the reinforcing column 4 by a plug-in connection, and the lower connector is connected to the sill beam 205 by bolts or other fasteners.

[0197] In some embodiments, the reinforcing column 4 is made of glass fiber reinforced composite material.

[0198] Glass fiber reinforced composite materials have advantages such as lightweight, high strength, good corrosion resistance, design flexibility, and ease of processing. Therefore, it is possible to improve the bending performance of the vehicle 1000 by reinforcing the column 4, while flexibly designing and conveniently manufacturing the reinforcing column 4.

[0199] In some embodiments, the reinforcing column 4 is made of glass fiber reinforced polyamide-6.

[0200] Because glass fiber reinforced polyamide-6 material has advantages such as high strength and high rigidity, it can further improve the strength and rigidity of the reinforcing column 4, thereby improving the strength and rigidity of the body frame 200, and thus enhancing the strength and rigidity of the vehicle 1000. Moreover, because glass fiber reinforced polyamide-6 material also has advantages such as good heat resistance and dimensional stability, it is suitable for application in the body. Furthermore, glass fiber reinforced polyamide-6 material has good processing performance and is suitable for processing by injection molding, extrusion molding, and other methods, making processing and manufacturing relatively easy. This is conducive to improving the production efficiency of the body frame 200, and thus improving the production efficiency of the vehicle 1000.

[0201] In some embodiments, glass fiber reinforced polyamide-6 comprises glass fiber and a thermoplastic resin matrix, wherein the weight percentage of the glass fiber is greater than or equal to 60 and less than or equal to 80, the weight percentage of the thermoplastic resin matrix is ​​greater than or equal to 20 and less than or equal to 40, and the sum of the weight percentages of the glass fiber and the thermoplastic resin matrix is ​​100.

[0202] This is beneficial for balancing the strength, rigidity, and ease of processing of the reinforced column 4.

[0203] In some embodiments, the glass fiber weight fraction of the glass fiber in the glass fiber reinforced polyamide-6 is greater than or equal to 68 or less than or equal to 75.

[0204] This will help to further optimize and strengthen the strength, rigidity, ease of processing, and aesthetics of column 4.

[0205] This can improve the strength and rigidity of the vehicle body pillar assembly.

[0206] In some embodiments, the vehicle 1000 also includes a battery device mounted on the chassis 100.

[0207] The reduced space occupied by the battery pack in the passenger compartment and trunk allows for more spacious seating and storage. Furthermore, mounting the battery pack on the chassis 100 reduces the direct impact on occupants during a collision with the vehicle 1000. Additionally, centralized mounting of the battery pack on the chassis 100 facilitates maintenance and replacement, reducing the complexity of routine maintenance.

[0208] In some embodiments, the housing of the battery device forms at least a portion of the floor of the passenger compartment.

[0209] By integrating the battery pack into the passenger compartment floor, additional supports and connectors can be reduced, which helps to reduce the overall vehicle weight and allows for more efficient use of the vehicle's interior space.

[0210] In some embodiments, the vehicle body frame 200 is detachably connected above the chassis 100.

[0211] This is arranged to achieve the separation and decoupling of the vehicle body frame 200 and the chassis 100, so that the vehicle body frame 200 can be replaced according to requirements, shortening the R & D cycle and reducing costs. In other words, it also improves the integration of the chassis 100 and enables it to be adapted to multiple vehicle models.

[0212] In a specific embodiment, as Figures 3 to 10 shown, the roll-formed reinforcing tube 1 is located in the area of the upper side member 204 of the vehicle body side wall. The reinforcing tube 1 and the upper side member 204 constitute at least part of the upper side member assembly. The reinforcing column 4 and a part of the frame beam main body 2 constitute the A-column assembly; another reinforcing column 4 and a part of the frame beam main body 2 constitute the B-column assembly; and yet another reinforcing column 4 and a part of the frame beam main body 2 constitute the C-column assembly; and still another reinforcing column 4 and a part of the frame beam main body 2 constitute the sill beam assembly. The A-column assembly, B-column assembly, and C-column assembly are connected between the upper side member assembly and the sill beam assembly to jointly form the side wall skeleton structure. The side wall skeleton structure bears the main frame structure of the upper vehicle body and improves the anti-collision performance of the vehicle 1000.

[0213] In some embodiments, as Figures 5 to 8 shown, the reinforcing tube 1 is connected to the reinforcing columns in the A-column assembly, the reinforcing columns in the B-column assembly, and the reinforcing columns in the C-column assembly. The cross-sectional shape of the reinforcing tube 1 is "day" shaped. The material of the reinforcing tube 1 is ultra-high-strength steel with a tensile strength of 1700 Mpa, and the wall thickness of the reinforcing tube 1 is 1.8 mm. The reinforcing tube 1 is connected to the first outer plate 221, the second outer plate 222, and the interior trim panel 3 through structural adhesive to form the upper side member assembly structure, improving the collision performance requirements and achieving structural lightweighting by using ultra-high-strength steel at the same time.

[0214] In some embodiments, as Figure 8 shown, the size of the first cavity 141 is greater than 20 mm, and the size of the second cavity 142 is greater than 20 mm. Thus, it can meet the requirements of the roller size, form the "day" shaped reinforcing tube 1 through roll-forming and bending, and at the same time perform laser welding to make parts.

[0215] The high-strength steel billet is processed into the reinforcement tube 1 through the roll forming process, replacing the traditional stamping process, simplifying the production process, and reducing the mold cost. The roll forming process can achieve complex curved surface shapes, meet the design requirements of the reinforcement tube 1, and extend the mold life. The laser welding technology is used to achieve the efficient connection of the reinforcement tube 1, replacing the traditional welding process, reducing complexity, and improving the connection reliability and production efficiency. The reinforcement tube 1 adopts a "day" - shaped structure and is connected to the reinforcement columns in the A - pillar assembly and the reinforcement columns in the C - pillar assembly to form an efficient force transmission path. The "day" - shaped structure reduces unnecessary material usage, optimizes the structural design, and further enhances the lightweight effect. By optimizing the design of the reinforcement tube 1, it is applicable to the requirements of the reinforcement tube 1 for various vehicle models, reducing the development cost. The combination of roll forming and laser welding technologies improves the versatility and market adaptability of the reinforcement tube 1.

[0216] This application significantly reduces the mold cost, simplifies the production process, and at the same time improves the lightweight and platform development capabilities of the reinforcement tube 1 by using 1700Mpa high - strength steel and the roll forming process, combined with laser welding technology and the "day" - shaped structure design. Through the optimized design and integrated connection method, the performance and production efficiency of the overall structure are further improved, providing an efficient solution for the lightweight and performance optimization of the body reinforcement tube 1.
