[0007] In some embodiments, the hinge mounting main plate is formed with a second groove recessed towards the second side, at least a part of the reinforcing structure is arranged in the second groove and connected with the groove wall of the second groove.

[0008] In the embodiment of the present application, the second groove is provided, which can play a role in strengthening the structural strength, and can also serve as an energy absorption area, thereby effectively absorbing and dispersing impact energy. In addition, the second groove can provide installation space for the reinforcing structure, and also facilitates increasing the bonding area of the reinforcing structure and the hinge mounting main plate, thereby improving the connection strength between the reinforcing structure and the hinge mounting main plate, and further improving the strength and deformation resistance of the vehicle body frame.

[0009] In some embodiments, the reinforcing structure comprises a reinforcing bottom plate and reinforcing side plates surrounding the reinforcing bottom plate, the reinforcing side plates are connected to the reinforcing bottom plate and extend towards the first side relative to the reinforcing bottom plate, the reinforcing bottom plate is arranged in the second groove and connected to the groove bottom wall of the second groove, and at least part of the reinforcing side plates is arranged in the second groove and connected to the groove side wall of the second groove.

[0010] In the embodiment of the present application, the reinforcing structure is provided in this structure, which improves the structural strength of the reinforcing structure. In addition, the reinforcing structure can also serve as an energy absorption area, thereby effectively absorbing and dispersing impact energy. Furthermore, the reinforcing bottom plate is connected to the groove bottom wall of the second groove, and the reinforcing side plates are connected to the groove side wall of the second groove, which increases the connection area of the hinge mounting main plate and the reinforcing structure, improves the connection strength therebetween, and further improves the strength and deformation resistance of the vehicle body frame.

[0011] In some embodiments, the reinforcing structure further comprises at least one first flange connected to the reinforcing side plate, the first flange is bent away from the reinforcing bottom plate relative to the reinforcing side plate, the reinforcing side plate is located at the rear side of the reinforcing pillar along the front-rear direction of the vehicle body, the first flange is connected to the outer surface of the reinforcing pillar facing the rear side of the vehicle body, and part of the reinforcing bottom plate is connected to the surface of the reinforcing pillar facing the second side.

[0012] In this way, the reinforcing bottom plate is connected to the surface of the reinforcing pillar facing the outer side of the vehicle body, and the first flange of the reinforcing structure is connected to the surface of the reinforcing pillar facing the rear side of the vehicle body, which increases the connection area of the hinge mounting assembly and the reinforcing pillar, improves the connection strength therebetween, and further improves the strength and deformation resistance of the vehicle body frame.

[0013] In some embodiments, the reinforcing side plate comprises a first side plate, a second side plate and a third side plate, all of which are connected to the reinforcing bottom plate, the first side plate and the third side plate are oppositely arranged along the extension direction of the reinforcing pillar, the second side plate is connected between the first side plate and the third side plate, and each end of the first side plate and the third side plate away from the second side plate is connected with a first flange, and the first flange is connected to the reinforcing pillar through the surface thereof away from the second side plate.

[0014] In this way, the first side plate, the second side plate, the third side plate, the first flange and the partial reinforcing bottom plate are located at the rear side of the reinforcing column along the front-rear direction of the vehicle body, thus, without increasing the space occupation along the inside-outside direction of the vehicle body, the structural strength of the hinge mounting assembly is enhanced, and thus the strength and deformation resistance of the vehicle body frame are further improved.

[0015] In some embodiments, the first side plate and / or the second side plate and / or the third side plate comprises at least two straight portions and at least one bent portion, and the bent portion is connected between adjacent straight portions along the direction around the reinforcing bottom plate, and the bent portion is recessed relative to the straight portion towards the side where the reinforcing bottom plate is provided.

[0016] In this way, by providing the bent portion on the side plate, the structural strength of the side plate is improved, and thus the structural strength of the reinforcing structure is further improved, and thus the strength and deformation resistance of the vehicle body frame are further improved.

[0017] In some embodiments, the hinge mounting main plate comprises at least one second flange, the second flange is connected with the groove side wall of the second groove and is bent relative to the groove side wall towards the outside of the second groove, and the second flange is connected with the surface of the first flange away from the reinforcing column.

[0018] In this way, by connecting the second flange with the first flange, the connecting area between the hinge mounting main plate and the reinforcing structure is further increased, and thus the connecting strength therebetween is improved, and thus the strength and deformation resistance of the vehicle body frame are further improved.

[0019] In some embodiments, the groove side wall of the second groove comprises a first portion and a second portion, two ends of the first portion are respectively connected with two ends of the second portion along the circumferential direction of the second groove, the second portion is protruded from the first portion along the direction towards the first side, and the protruded portion is connected with the second flange at at least one end along the circumferential direction of the second groove.

[0020] In this way, the setting position of the second flange is appropriate, and the first flange of the reinforcing structure is convenient to connect. Moreover, by setting the dimension of the second portion along the inside-outside direction of the vehicle body to be relatively large, the structural strength of the hinge mounting main plate is improved, and thus the strength and deformation resistance of the vehicle body frame are further improved.

[0021] In some embodiments, the hinge mounting main plate further comprises an extension portion, the extension portion is connected with the edge of the first portion away from the groove bottom wall of the second groove and extends towards the outside of the second groove, and the extension portion is connected with the surface of the reinforcing column facing the second side.

[0022] In this way, by connecting the extension portion with the surface of the reinforcing column facing the outside of the vehicle body, the connecting area between the hinge mounting main plate and the reinforcing column is further increased, and thus the connecting strength therebetween is improved, and thus the strength and deformation resistance of the vehicle body frame are further improved.

[0023] In some embodiments, the groove bottom wall of the second groove is formed with a first connecting hole extending along the inside-outside direction of the vehicle body, the reinforcing bottom plate is formed with a second connecting hole extending along the inside-outside direction of the vehicle body, the hinge mounting assembly further comprises a first connecting piece and a first fastener, the first connecting piece is connected with the reinforcing column, the first fastener comprises a first insertion part and a first abutting part connected with each other, the first insertion part sequentially passes through the door hinge, the first connecting hole and the second connecting hole and is connected with the first connecting piece, and the first abutting part abuts against the surface of the door hinge.

[0024] In this way, through the connection of the first connecting piece and the first fastener, not only the door hinge is fastened to the hinge mounting main plate, but also the hinge mounting main plate, the reinforcing structure and the reinforcing column are further connected, the connection strength among the three is further improved, and the strength and the deformation resistance of the vehicle body frame are further improved.

[0025] In some embodiments, the reinforcing column is formed with a mounting hole, and at least part of the first connecting piece is embedded in the mounting hole.

[0026] Through the arrangement of the mounting hole, the connection area of the first connecting piece and the mounting hole is increased, and the connection strength of the two is improved; and the mounting hole also plays a role of avoiding the first connecting piece, which is beneficial to reducing the occupation of the space in the inside-outside direction of the vehicle body.

[0027] In some embodiments, the first connecting piece is formed with a third connecting hole extending along the inside-outside direction of the vehicle body, and the first insertion part extends into the third connecting hole and is connected with the third connecting hole.

[0028] In this way, since the first connecting piece is formed with the third connecting hole, the first fastener is connected to the first connecting piece after passing through the door hinge, the first connecting hole and the second connecting hole, so that the door hinge is connected to the hinge mounting assembly, and the structure is simple and convenient to manufacture.

[0029] In some embodiments, the groove bottom wall of the second groove is further formed with a fourth connecting hole extending along the inside-outside direction of the vehicle body, the reinforcing bottom plate is formed with a fifth connecting hole extending along the inside-outside direction of the vehicle body, the fourth connecting hole and the fifth connecting hole have a spacing from the projection of the reinforcing column in the inside-outside direction of the vehicle body, and the hinge mounting assembly further comprises a second fastener, the second fastener comprises a second insertion part and a second abutting part connected with each other, the second insertion part sequentially passes through the fifth connecting hole and the fourth connecting hole and is connected with the door hinge, and the second abutting part abuts against the surface of the reinforcing bottom plate away from the groove bottom wall.

[0030] The orthographic projections of the fourth and fifth connecting holes are spaced apart from the orthographic projection of the reinforcing pillar. That is, the fourth and fifth connecting holes are offset from the reinforcing pillar towards the rear of the vehicle body. Therefore, the second insertion part of the second fastener can be inserted from one side of the recessed area of ​​the reinforcing structure, and pass through the fifth and fourth connecting holes in sequence to connect with the door hinge. The second abutting part of the second fastener abuts against the surface of the recessed area of ​​the reinforcing structure, thereby fastening the door hinge to the hinge mounting plate through the second fastener. Moreover, the second fastener further connects the hinge mounting plate and the reinforcing structure, further improving the connection strength between the two, and further improving the strength of the vehicle body frame and its resistance to deformation.

[0031] In some embodiments, the hinge mounting motherboard is formed as a one-piece stamped structure; and / or, the reinforcing structure is formed as a one-piece stamped structure.

[0032] One-piece stamping structure is a one-piece structure formed by stamping process. This structure can reduce the number of welding points of parts, reduce the risk of quality defects, and improve production efficiency and consistency.

[0033] In some embodiments, the wall thickness of the hinge mounting motherboard is greater than or equal to 1.5 mm and less than or equal to 1.8 mm; the reinforcing structure adopts a plate-like structure, and its wall thickness is greater than or equal to 1.8 mm and less than or equal to 2.0 mm.

[0034] In this way, the thickness of the hinge mounting board and the reinforcing structure is set within an appropriate range to meet their respective structural strength requirements, while also taking up little space and being lightweight.

[0035] In some embodiments, the hinge mounting motherboard is made of HC340 / 590DP steel; the reinforcing structure is made of HC420 / 780DP steel.

[0036] By using the aforementioned materials, the hinge mounting plate and reinforcing structure achieve high strength and rigidity, enhancing the strength and resistance to deformation of the door hinge mounting area. Furthermore, employing materials with relatively high yield strength and tensile strength in the reinforcing structure further enhances its strength-boosting effect.

[0037] In some embodiments, the reinforcing column is configured as a tube shell with a closed cross-section.

[0038] Because the reinforcing column is constructed as a tubular shell with a closed cross-section, it can effectively absorb impact energy and possesses high strength and rigidity, thereby improving the strength of the vehicle frame and its resistance to deformation. Furthermore, it is easy to process and install, which helps improve vehicle assembly efficiency and shorten the vehicle manufacturing cycle.

[0039] In some embodiments, the reinforcing column is configured as a tube shell having a closed cross section and a reinforcing assembly built in the tube shell.

[0040] The reinforcing assembly is used to further enhance the strength of the reinforcing column. For example, the reinforcing assembly can include reinforcing ribs, reinforcing plates or other structures that can be used to enhance the strength of the tube shell.

[0041] In some embodiments, the reinforcing assembly includes at least one first reinforcing rib connected to the inner wall of the tube shell.

[0042] Since the first reinforcing rib is connected to the inner wall of the tube shell, the space in the lumen of the tubular reinforcing structure can be effectively utilized, and the strength and stiffness of the reinforcing column can be enhanced without increasing the outer contour size of the tubular reinforcing structure, and bending deformation is less likely to occur, thereby improving the strength and resistance to deformation of the vehicle body frame.

[0043] In some embodiments, the reinforcing column is configured as an integrally rolled tube having a closed cross section.

[0044] The reinforcing column is an integrally rolled tube, on the one hand, the one-piece forming reduces the welding points, reduces the fatigue risk caused by the weld, prolongs the service life of the vehicle, on the other hand, the rolling forming process simplifies the production process, reduces the mold cost and production cycle.

[0045] In some embodiments, the thickness of the tube wall of the reinforcing column is greater than or equal to 1.8 mm and less than or equal to 2.2 mm.

[0046] In this way, the thickness of the tube wall of the reinforcing column is set within an appropriate range to meet the respective requirements for structural strength, and the thickness is not too large to occupy a small space and have a light weight.

[0047] In some embodiments, the material of the reinforcing column includes QP1180 steel.

[0048] In this way, the reinforcing column uses QP1180 steel, so that the reinforcing column has high strength and can withstand large mechanical loads, improving the tensile strength and crash energy absorption performance of the reinforcing column.

[0049] In some embodiments, the number of hinge mounting assemblies is at least two, the at least two hinge mounting assemblies include at least one first hinge mounting assembly and at least one second hinge mounting assembly; the number of door hinges is at least two, the at least two door hinges include at least one upper door hinge and at least one lower door hinge, the upper door hinge is connected to the upper part of the reinforcing column through the first hinge mounting assembly, and the lower door hinge is connected to the lower part of the reinforcing column through the second hinge mounting assembly.

[0050] The distance between the upper door hinge and the lower door hinge in the up-down direction of the vehicle body can be increased as much as possible, so that the door downward load of the upper door hinge and the lower door hinge can be better dispersed to the reinforcing column. Since the upper door hinge and the lower door hinge are connected to the reinforcing column to form an integrated structure, the reinforcing column can share the force acting on the upper door hinge and the lower door hinge, thereby improving the overall structural stiffness, reducing stress concentration at the hinge, facilitating deformation at the hinge, and thereby improving the ability of the vehicle body frame to resist deformation.

[0051] In some embodiments, at least part of the frame beam body constitutes an A-pillar, a B-pillar and a C-pillar of the vehicle, and at least part of the frame beam body constituting at least one of the A-pillar, the B-pillar and the C-pillar is provided with the first groove, and the reinforcing column is arranged in the first groove and mounted with the door through the hinge mounting assembly and the door hinge.

[0052] The reinforcing column arranged in the first groove of at least one of the A-pillar, the B-pillar and the C-pillar can improve the structural strength and stiffness of the frame beam body, improve the bending resistance and deformation resistance of the frame beam body, and thereby improve the anti-impact performance of the vehicle.

[0053] In some embodiments, the vehicle further comprises a chassis, and the vehicle body frame is arranged above the chassis and detachably connected with the chassis.

[0054] In this way, the vehicle body frame and the chassis are decoupled, so that the vehicle body frame can be replaced as needed, thereby shortening the development cycle and reducing costs. In other words, the integration of the chassis can be improved to adapt to various vehicle models.

[0055] In some embodiments, the vehicle further comprises a chassis, and the vehicle body frame is mounted on the chassis and forms a passenger compartment together with the chassis, and the vehicle further comprises a battery device mounted on the chassis, and a shell of the battery device forms at least part of a floor of the passenger compartment.

[0056] By integrating the battery device into the floor of the passenger compartment, additional supports and connecting members can be reduced, which helps to reduce the overall weight of the vehicle, and the internal space of the vehicle can be more effectively utilized.

[0057] The beneficial effects of the embodiments of the present disclosure include that a vehicle with high anti-impact performance is provided. BRIEF DESCRIPTION OF DRAWINGS

[0084] The application will be described in detail below.

[0085] The crashworthiness of a vehicle is related to the degree of intrusion of the vehicle structure into the passenger compartment or the degree of damage of the vehicle, and thus to the personal safety of passengers.

[0086] The inventors of the present application have noticed that when the vehicle is hit from the side, the stress at the door hinge mounting position is relatively large, deformation is prone to occur at this position, and the intrusion into the passenger compartment is relatively large, so the crashworthiness of the vehicle is poor. Therefore, increasing the structural strength of the hinge mounting position helps to reduce the intrusion amount during side impact and improve the crashworthiness of the vehicle.

[0087] To this end, the inventors of the present application have designed a vehicle, which comprises a vehicle body frame having a first side facing the inside of the vehicle body and a second side facing the outside of the vehicle body, the vehicle body frame comprising a frame beam body, a reinforcing column, a hinge mounting assembly, and a door hinge, the frame beam body being formed with a first recess recessed toward the second side; the reinforcing column at least partially filling the first recess of the frame beam body; the hinge mounting assembly comprising a hinge mounting main plate and a reinforcing structure connected to the first side of the hinge mounting main plate, the hinge mounting main plate and the reinforcing structure being connected to the reinforcing column, and the door hinge being connected to the second side of the hinge mounting main plate and connected to the door.

[0088] On the one hand, the reinforcing column filling the first recess of the frame beam body can improve the strength of the frame beam body, thereby improving the ability of the vehicle to resist deformation and reducing the degree of damage to the vehicle. On the other hand, the side of the hinge mounting main plate facing the inside of the vehicle body is connected to the reinforcing structure, and the hinge mounting main plate and the reinforcing structure are both connected to the reinforcing column, which can improve the structural strength of the hinge mounting main plate, and the hinge mounting main plate is connected to the door hinge. Therefore, the structural strength of the position where the door hinge of the vehicle is mounted is high, and under the condition that the vehicle body frame is subjected to a side impact force, bending deformation is not prone to occur at this position, which is conducive to improving the strength and deformation resistance of the vehicle body frame, thereby improving the impact resistance of the vehicle.

[0089] In addition, the frame beam body is formed with the first recess, which can not only improve the structural strength of the frame beam body, but also serve as an energy absorption zone, thereby effectively absorbing and dispersing impact energy. On the other hand, the first recess can provide mounting space for the reinforcing column, and the combination of the first recess and the reinforcing column increases the connection strength between the reinforcing column and the frame beam body, thereby further improving the strength and deformation resistance of the vehicle body frame.

[0090] In the following embodiments, for the convenience of description, the following will be described with reference to the accompanying drawings.

[0091] Figure 1 The exploded structural schematic diagram of the vehicle 1000 provided for some embodiments of the present application is shown.

[0092] The vehicle 1000 can be a fuel automobile, a gas automobile, or a new energy automobile, and the new energy automobile can be a pure electric vehicle, a hybrid vehicle, or an extended range vehicle. The embodiments of the present application do not have special restrictions on the above vehicles. For example,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.

[0093] For example, the body frame 200 and the chassis 100 are welded together.

[0094] In some embodiments of this application, the chassis 100 and the body frame 200 are detachably connected.

[0095] 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.

[0096] 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.

[0097] In some embodiments of this application, the vehicle frame 200 and chassis 100 together enclose the passenger compartment of the vehicle 1000, the vehicle 1000 including a battery device, the housing of the battery device forming at least a portion of the floor of the passenger compartment.

[0098] 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.

[0099] Figure 2 An exploded perspective view of a vehicle 1000 (excluding chassis 100) provided for some embodiments of this application.

[0100] 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.

[0103] In some embodiments of the present application, in order to facilitate the description, the inner and outer directions of the vehicle body, the front and rear directions of the vehicle body, and the up and down directions of the vehicle body are set, in the drawings of the present application, the direction in which the arrow a-b is located is the "inner and outer directions of the vehicle body", the direction in which the arrow c-d is located is the "front and rear directions of the vehicle body", and the direction in which the arrow e-f is located is the "up and down directions of the vehicle body", wherein the direction indicated by the arrow a is the inner side of the vehicle body, the direction indicated by the arrow b is the outer side of the vehicle body, the direction indicated by the arrow c is the front side of the vehicle body, the direction indicated by the arrow d is the rear side of the vehicle body, the direction indicated by the arrow e is the upper side of the vehicle body, and the direction indicated by the arrow f is the lower side of the vehicle body.

[0104] As Figures 2 to 5 shown, the present application provides a vehicle 1000, the vehicle 1000 comprising a vehicle body frame 200, the vehicle body frame 200 having a first side facing the inner side a of the vehicle body and a second side facing the outer side b of the vehicle body, the vehicle body frame 200 comprising a frame beam body 20, a reinforcing pillar 30, a hinge mounting assembly 10, and a door hinge 40, the frame beam body 20 being formed with a first recess 210 recessed towards the second side; at least part of the reinforcing pillar 30 being filled in the first recess 210 of the frame beam body 20; the hinge mounting assembly 10 comprising a hinge mounting main plate 1 and a reinforcing structure 2 connected to the first side of the hinge mounting main plate 1, the hinge mounting main plate 1 and the reinforcing structure 2 are both connected with the reinforcing pillar 30, the door hinge 40 is connected to the second side of the hinge mounting main plate 1 and connected with the door 209.

[0105] Specifically, the vehicle body frame 200 has a first side facing an inner side of the vehicle body frame 200 and a second side facing an outer side of the vehicle body frame 200, the outer side of the vehicle body frame 200 is also referred to as a vehicle body outer side, and the inner side of the vehicle body frame 200 is also referred to as a vehicle body inner side. The frame beam body 20 is formed with a first groove 210 recessed toward the second side, that is, the first groove 210 is recessed toward the vehicle body outer side, and the opening of the first groove 210 faces the inner side of the vehicle body frame 200. The reinforcing column 30 is arranged on the first side and arranged in the first groove 210 and connected with the frame beam body 20.

[0106] Exemplarily, the reinforcing column 30 is arranged in the first groove 210 of the frame beam body 20 in an adhesive manner by structural adhesive.

[0107] The structural adhesive includes but is not limited to epoxy-based structural adhesive, silicone structural adhesive, polyurethane structural adhesive, etc.

[0108] Exemplarily, the door hinge 40 can be made of carbon steel, high-strength steel, aluminum alloy, carbon fiber composite material, etc.

[0109] The door hinge 40 can be a hinge commonly used by those skilled in the art, and the material and shape of the door hinge 40 are not limited in the present application.

[0110] In the embodiments of the present application, on the one hand, the reinforcing column 30 is arranged in the first groove 210 of the frame beam body 20, which can improve the strength of the frame beam body 20, thereby improving the deformation resistance of the vehicle 1000 and reducing the damage degree of the vehicle 1000. On the other hand, the side of the hinge mounting main plate 1 facing the vehicle body inner side is connected with the reinforcing structure 2, and the hinge mounting main plate 1 and the reinforcing structure 2 are both connected with the reinforcing column 30, which can improve the structural strength of the hinge mounting main plate 1. In addition, the hinge mounting main plate 1 is connected with the door hinge 40, so that the structural strength of the position where the door hinge 40 is mounted on the vehicle 1000 is high, and in the case that the vehicle body frame 200 is subjected to a side impact force, bending deformation is less likely to occur at this position, which is beneficial to improving the strength and deformation resistance of the vehicle body frame 200, thereby improving the impact resistance of the vehicle 1000.

[0111] In addition, the first groove 210 can play a role in strengthening the structural strength and also serve as an energy absorption area, thereby effectively absorbing and dispersing impact energy. On the other hand, the first groove 210 can provide mounting space for the reinforcing column 30, and due to the increased bonding area between the first groove 210 and the reinforcing column 30, the connection strength between the reinforcing column 30 and the frame beam body 20 is improved, thereby further improving the strength and deformation resistance of the vehicle body frame 200.

[0112] In some embodiments, asFigures 5 to 8 As shown, the hinge mounting main board 1 has a second groove 101 recessed towards the second side, and at least a portion of the reinforcing structure 2 is disposed in the second groove 101 and connected to the groove wall of the second groove 101.

[0113] For example, the reinforcing structure 2 is welded to the groove wall of the second groove 101.

[0114] For example, the reinforcing structure 2 is bonded to the groove wall of the second groove 101 by an adhesive, which includes, but is not limited to, structural adhesive.

[0115] For example, part of the reinforcing structure 2 is disposed in the second groove 101, and the rest extends out through the slot of the second groove 101.

[0116] For example, the entire reinforcing structure 2 is disposed within the second groove 101.

[0117] In this embodiment, the second groove 101 serves two purposes: firstly, it strengthens the structure and acts as an energy-absorbing zone, effectively absorbing and dispersing impact energy; secondly, it provides installation space for the reinforcing structure 2 and increases the contact area between the reinforcing structure 2 and the hinge mounting plate 1, thereby improving the connection strength between the reinforcing structure 2 and the hinge mounting plate 1 and further enhancing the strength and resistance to deformation of the vehicle frame 200.

[0118] Of course, it is understandable that the structure of the hinge mounting motherboard 1 is not limited to setting the second groove 101. The hinge mounting motherboard 1 can also be a plate-like structure without a groove.

[0119] In some embodiments, such as Figures 8 to 10 As shown, the reinforcing structure 2 includes a reinforcing base plate 21 and a reinforcing side plate 22 surrounding the reinforcing base plate 21. The reinforcing side plate 22 is connected to the reinforcing base plate 21 and extends toward the first side relative to the reinforcing base plate 21. The reinforcing base plate 21 is disposed in the second groove 101 and connected to the bottom wall 11 of the second groove 101. At least a portion of the reinforcing side plate 22 is disposed in the second groove 101 and connected to the side wall 12 of the second groove 101.

[0120] It should be noted that the reinforcing side plate 22 can surround the reinforcing base plate 21 in a complete circle, or it can surround the reinforcing base plate 21 in a half circle, or the area of ​​the surrounding area is less than half a circle or more than half a circle, etc. No specific restrictions are made here.

[0121] It can be understood that the reinforcing side plate 22 is connected to the reinforcing bottom plate 21 and extends towards the first side relative to the reinforcing bottom plate 21, that is, the reinforcing side plate 22 is arranged on the first side of the reinforcing bottom plate 21, in other words, the reinforcing side plate 22 is arranged on the inner side of the reinforcing bottom plate 21 along the inside-outside direction a-b of the vehicle body, and further, the reinforcing side plate 22 and the reinforcing bottom plate 21 form a recessed part recessed towards the outside b of the vehicle body.

[0122] As shown in Figure 8 and Figure 10 , the reinforcing side plate 22 is welded to the groove side wall 12 of the second groove 101.

[0123] As shown in , the reinforcing side plate 22 is bonded to the groove side wall 12 of the second groove 101 by an adhesive, which includes but is not limited to structural glue.

[0124] Figure 8 As shown in Figure 10 and , the reinforcing bottom plate 21 is welded to the groove bottom wall 11 of the second groove 101.

[0125] As shown in

[0126] , the reinforcing bottom plate 21 is bonded to the groove bottom wall 11 of the second groove 101 by an adhesive, which includes but is not limited to structural glue.

[0127] In the embodiments of the present application, the reinforcing structure 2 is arranged in such a structure, which improves the structural strength of the reinforcing structure 2, and further, the reinforcing structure 2 can also serve as an energy absorption area, thereby effectively absorbing and dispersing impact energy. In addition, the reinforcing bottom plate 21 is connected to the groove bottom wall 11 of the second groove 101, and the reinforcing side plate 22 is connected to the groove side wall 12 of the second groove 101, which increases the connection area between the hinge mounting main plate 1 and the reinforcing structure 2, improves the connection strength therebetween, and further improves the strength and deformation resistance of the vehicle body frame 200.

[0128] Of course, it can be understood that the reinforcing structure 2 is not limited to the above structure, and the reinforcing structure 2 can also include but is not limited to a plurality of reinforcing ribs arranged in cross, which is not limited here.

[0129] In some embodiments, as shown in Figure 10 , the reinforcing structure 2 further includes at least one first flange 23 connected to the reinforcing side plate 22, the first flange 23 is bent relative to the reinforcing side plate 22 towards the side away from the reinforcing bottom plate 21, the reinforcing side plate 22 is located on the rear side of the reinforcing column 30 along the front-rear direction c-d of the vehicle body, the first flange 23 is connected to the outer surface of the reinforcing column 30 facing the rear side d of the vehicle body, and part of the reinforcing bottom plate 21 is connected to the surface of the reinforcing column 30 facing the second side.

[0130] Optionally, the first flange 23 can be provided in one, two, three or more numbers, which is not specifically limited here.

[0131] As shown in the examples, Figure 10 The first flange 23 is provided in two numbers, and the two first flanges 23 are respectively arranged on the opposite sides of the reinforcing side plate 22 along the extension direction of the reinforcing column 30.

[0132] In this way, the surface of the reinforcing bottom plate 21 facing the vehicle body outer side b is connected with the reinforcing column 30, and the first flange 23 of the reinforcing structure 2 is connected with the surface of the reinforcing column 30 facing the vehicle body rear side d, thereby increasing the connection area of the hinge mounting assembly 10 and the reinforcing column 30, improving the connection strength of the hinge mounting assembly 10 and the reinforcing column 30, and further improving the strength and deformation resistance of the vehicle body frame 200.

[0133] In some embodiments, as shown in the examples, Figure 10 and Figure 12 The reinforcing side plate 22 includes a first side plate 221, a second side plate 222 and a third side plate 223, all of which are connected with the reinforcing bottom plate 21. The first side plate 221 and the third side plate 223 are oppositely arranged along the extension direction of the reinforcing column 30, and the second side plate 222 is connected between the first side plate 221 and the third side plate 223. Each end of the first side plate 221 and the third side plate 223 away from the second side plate 222 is respectively connected with a first flange 23, and the surface of the first flange 23 away from the second side plate 222 is connected with the outer surface of the reinforcing column 30 facing the vehicle body rear side d.

[0134] As an example, the first side plate 221 is located on the upper side along the vehicle body vertical direction e-f relative to the third side plate 223, and the size of the first side plate 221 is smaller than the size of the third side plate 223 along the vehicle body front-rear direction c-d.

[0135] As an example, the first flange 23 is welded with the reinforcing column 30.

[0136] As an example, the first flange 23 is bonded with the reinforcing column 30 by an adhesive, which includes but is not limited to structural adhesive.

[0137] It can be understood that the first side plate 221, the second side plate 222 and the third side plate 223 can be connected by welding, or can be connected by bonding, etc. The first side plate 221, the second side plate 222 and the third side plate 223 can also be formed as an integral structure.

[0138] As an example, the opening is formed between the end of the first side plate 221 and the third side plate 223 away from the second side plate 222 and the reinforcing bottom plate 21, and the two first flanges 23 are respectively located on the opposite sides of the opening along the extension direction of the reinforcing column 30.

[0139] Exemplarily, another side plate is connected between the ends of the first side plate 221 and the third side plate 223 away from the second side plate 222, and the another side plate is connected with the reinforcing bottom plate 21.

[0140] In this way, the first side plate 221, the second side plate 222, the third side plate 223, the first flange 23 and part of the reinforcing bottom plate 21 are located at the rear side of the reinforcing column 30 along the vehicle body front-rear direction c-d, thus, without increasing the space occupied in the vehicle body inner-outer direction a-b, the structural strength of the hinge mounting assembly 10 is enhanced, thereby further improving the strength and deformation resistance of the vehicle body frame 200.

[0141] Of course, it can be understood that the reinforcing side plate 22 is not limited to the above-mentioned three side plates (the first side plate 221, the second side plate 222 and the third side plate 223), and in some other embodiments, the reinforcing side plate 22 can also be provided as four, five or more side plates, which are not specifically limited here.

[0142] In some embodiments, as shown in Figure 12 The first side plate 221 and / or the second side plate 222 and / or the third side plate 223 includes at least two straight portions 224 and at least one bent portion 225, and the bent portion 225 is connected between adjacent straight portions 224 along the direction around the reinforcing bottom plate 21, and the bent portion 225 is recessed relative to the straight portion 224 towards the side where the reinforcing bottom plate 21 is provided.

[0143] It can be understood that the first side plate 221 and / or the second side plate 222 and / or the third side plate 223 includes the bent portion 225, so that the first side plate 221 and / or the second side plate 222 and / or the third side plate 223 is not a straight plate, and in the case of the same wall thickness and the same material, the plate with the bent portion 225 has higher structural strength than the straight plate.

[0144] Exemplarily, the bent portion 225 extends along the vehicle body inner-outer direction a-b, and the two ends thereof extend to the edges of the reinforcing bottom plate 21 and the reinforcing side plate 22 away from the reinforcing bottom plate 21, respectively. In this way, the strength of the reinforcing side plate 22 along the vehicle body inner-outer direction a-b is improved, and deformation is less likely to occur when subjected to lateral impact.

[0145] In this way, by providing the bent portion 225 on the side plate, the structural strength of the side plate is improved, and the structural strength of the reinforcing structure 2 is further improved, thereby further improving the strength and deformation resistance of the vehicle body frame 200.

[0146] In some embodiments, as shown in Figures 10 to 12As shown, the hinge mounting main plate 1 comprises at least one second flange 13, which is connected with the groove side wall 12 of the second groove 101 and is bent outwards of the second groove 101 relative to the groove side wall 12, and the second flange 13 is connected with the surface of the first flange 23 away from the reinforcing column 30.

[0147] For example, the first flange 23 is welded with the second flange 13.

[0148] For example, the first flange 23 is bonded with the second flange 13 by an adhesive, which includes but is not limited to structural adhesive.

[0149] Optionally, the second flange 13 can be provided in one, two, three or more numbers, which is not specifically limited here.

[0150] For example, the second flange 13 is provided in two, and the two second flanges 13 are respectively arranged on the opposite sides of the groove side wall 12 along the extension direction of the reinforcing column 30.

[0151] In this way, by connecting the second flange 13 with the first flange 23, the connecting area between the hinge mounting main plate 1 and the reinforcing structure 2 is further increased, the connecting strength of the two is improved, and the strength and deformation resistance of the vehicle body frame 200 are further improved.

[0152] In some embodiments, as shown in Figure 10 and Figure 11 As shown, the groove side wall 12 of the second groove 101 comprises a first part 121 and a second part 122, and along the circumferential direction of the second groove 101, the two ends of the first part 121 are respectively connected with the two ends of the second part 122, the second part 122 extends beyond the first part 121 in the direction towards the first side, and the extended part is connected with the second flange 13 at least at one end along the circumferential direction of the second groove 101.

[0153] For example, the part of the second part 122 extending beyond the first part 121 in the direction towards the first side is respectively connected with one second flange 13 at both ends along the circumferential direction of the second groove 101.

[0154] It can be understood that, along the circumferential direction of the second groove 101, the two ends of the first part 121 are respectively connected with the two ends of the second part 122, which means that the first part 121 is connected with the second part 122 to form a closed annular side wall.

[0155] It can be understood that the second part 122 exceeds the first part 121 in the direction towards the first side, that is, in the vehicle body inner-outer direction a-b, the size of the second part 122 is greater than that of the first part 121. Since the second flange 13 is connected with the part of the second part 122 exceeding the first part 121, and the second flange 13 is connected with the surface of the first flange 23 away from the reinforcing column 30, the second part 122 is arranged at the rear side of the reinforcing column 30 in the vehicle body front-rear direction c-d, and the first part 121 is arranged at the outer side of the reinforcing column 30 in the vehicle body inner-outer direction a-b.

[0156] For example, the second part 122 is arranged around the outer circumferential side of the reinforcing side plate 22, and the mutually facing surfaces of the two are connected, which can be connected by welding, bonding or fastening by screws and the like.

[0157] For example, the second part 122 is connected with the first side plate 221, another part of the second part 122 is connected with the second side plate 222, and still another part of the second part 122 is connected with the third side plate 223.

[0158] In this way, the arrangement position of the second flange 13 is appropriate, facilitating the connection with the first flange 23 of the reinforcing structure 2. Moreover, by arranging the first part 121 of the slot side wall 12 around the outer circumferential side of the part of the reinforcing bottom plate 21 abutting against the reinforcing column 30, the surface of the reinforcing column 30 facing the vehicle body outer side can be connected with the reinforcing bottom plate 21 and the hinge mounting main plate 1. In addition, by arranging the size of the second part 122 in the vehicle body inner-outer direction a-b to be relatively large, the structural strength of the hinge mounting main plate 1 is improved, further improving the strength and deformation resistance of the vehicle body frame 200.

[0159] Of course, it can be understood that the arrangement of the slot side wall 12 of the second recess 101 is not limited to the above structure. In some other embodiments, the size of the slot side wall 12 of the second recess 101 in the vehicle body inner-outer direction a-b is the same at different positions.

[0160] In some embodiments, as shown in Figures 10 to 13 The hinge mounting main plate 1 further comprises an extension part 14 connected with the edge of the first part 121 away from the slot bottom wall 11 of the second recess 101 and extending towards the slot outer side of the second recess 101, and the extension part 14 is connected with the surface of the reinforcing column 30 facing the second side.

[0161] For example, the extension part 14 is welded with the reinforcing column 30.

[0162] For example, the extension part 14 is bonded with the reinforcing column 30 by an adhesive, which includes but is not limited to structural adhesive.

[0163] Thus, by connecting the surface of the reinforcing column 30 facing the outside of the vehicle body b with the extension part 14, the connecting area between the hinge mounting main plate 1 and the reinforcing column 30 is further increased, the connecting strength between the hinge mounting main plate 1 and the reinforcing column 30 is improved, and the strength and the deformation resistance of the vehicle body frame 200 are further improved.

[0164] In some embodiments, as shown in Figure 5 , Figure 8 and Figure 10 , the bottom wall 11 of the second groove 101 is formed with a first connecting hole 111 extending along the vehicle body inside-outside direction a-b, the reinforcing bottom plate 21 is formed with a second connecting hole 211 extending along the vehicle body inside-outside direction a-b, the hinge mounting assembly 10 further comprises a first connecting piece 3 and a first fastener 4, the first connecting piece 3 is connected with the reinforcing column 30, the first fastener 4 comprises a first inserting part and a first abutting part connected with each other, the first inserting part passes through the door hinge 40, the first connecting hole 111 and the second connecting hole 211 in sequence and is connected with the first connecting piece 3, and the first abutting part abuts against the surface of the door hinge 40.

[0165] Optionally, the first fastener 4 can be a bolt or a screw, etc.

[0166] Optionally, the first connecting piece 3 can be a block or a threaded sleeve, etc.

[0167] Thus, by the connection of the first connecting piece 3 and the first fastener 4, not only the door hinge 40 is fastened to the hinge mounting main plate 1, but also the hinge mounting main plate 1, the reinforcing structure 2 and the reinforcing column 30 are further connected, the connecting strength among the three is further improved, and the strength and the deformation resistance of the vehicle body frame 200 are further improved.

[0168] In some embodiments, as shown in Figure 8 and Figure 14 , the reinforcing column 30 is formed with a mounting hole 301, and at least part of the first connecting piece 3 is embedded in the mounting hole 301.

[0169] By the provision of the mounting hole 301, the connecting area between the first connecting piece 3 and the mounting hole 301 is increased, and the connecting strength between the two is improved; and the mounting hole 301 also plays a role of avoiding the first connecting piece 3, which is beneficial to reducing the occupation of the space in the vehicle body inside-outside direction a-b.

[0170] In some embodiments, as shown in Figure 8 , the first connecting piece 3 is formed with a third connecting hole 31 extending along the vehicle body inside-outside direction a-b, and the first inserting part extends into the third connecting hole 31 and is connected with the third connecting hole 31.

[0171] In some examples, the cross-sectional area of the third connecting hole 31 can be constant or variable along the in-out direction a-b of the vehicle body, but the size of the third connecting hole 31 is required to be able to allow a part of the first insertion part of the first fastener 4 to pass through, thereby connecting the first insertion part with the third connecting hole 31.

[0172] In some examples, the part of the first connecting member 3 connected with the first insertion part can have an internal thread, and the first insertion part can have an external thread, and the first connecting member 3 and the first fastener 4 are connected by the threads.

[0173] In some examples, a steel wire thread sleeve can be added in the third connecting hole 31 to reduce the probability of wire slipping after the vehicle door hinge 40 is disassembled multiple times.

[0174] Thus, since the first connecting member 3 is formed with the third connecting hole 31, it is convenient for the first fastener 4 to pass through the vehicle door hinge 40, the first connecting hole 111, and the second connecting hole 211 and then be connected to the first connecting member 3, so that the vehicle door hinge 40 is connected to the hinge mounting assembly 10, which is simple in structure and convenient to manufacture.

[0175] In some embodiments, as shown in Figs. 1-3, the second recess 101 is further formed with a fourth connecting hole 112 extending along the in-out direction a-b of the vehicle body, and the reinforcing bottom plate 21 is formed with a fifth connecting hole 212 extending along the in-out direction a-b of the vehicle body. The fourth connecting hole 112 and the fifth connecting hole 212 are spaced apart from the projection of the reinforcing column 30 along the in-out direction a-b of the vehicle body. The hinge mounting assembly 10 further comprises a second fastener comprising a second insertion part and a second abutting part connected with each other. The second insertion part passes through the fifth connecting hole 212 and the fourth connecting hole 112 in sequence and is connected with the vehicle door hinge 40. The second abutting part abuts against the surface of the reinforcing bottom plate 21 away from the groove bottom wall 11. Figure 5 Figure 8 Figure 10

[0176] Exemplarily, the second fastener can be a bolt or a screw, etc.

[0177] Exemplarily, the vehicle door hinge 40 has a threaded hole, and the second insertion part extends into the threaded hole of the vehicle door hinge 40 after passing through the fifth connecting hole 212 and the fourth connecting hole 112 in sequence and is screwed with the threaded hole.

[0178] Exemplarily, the fourth connecting hole 112 of the groove bottom wall 11 of the second recess 101 is arranged at the rear side of the first connecting hole 111 along the front-rear direction c-d of the vehicle body and is spaced apart from the first connecting hole 111. The fifth connecting hole 212 of the reinforcing bottom plate 21 is arranged at the rear side of the second connecting hole 211 along the front-rear direction c-d of the vehicle body and is spaced apart from the second connecting hole 211.

[0179] ​​​The fourth connecting hole 112 and the fifth connecting hole 212 are both spaced apart from the projection of the reinforcing column 30, that is, the fourth connecting hole 112 and the fifth connecting hole 212 are offset from the reinforcing column 30 towards the rear side d of the vehicle body. Therefore, the second insertion part of the second fastener can be inserted from one side of the recessed area of the reinforcing structure 2, and sequentially pass through the fifth connecting hole 212 and the fourth connecting hole 112 to be connected with the door hinge 40. The second abutting part of the second fastener abuts against the surface in the recessed area of the reinforcing structure 2, so that the door hinge 40 is fastened to the hinge mounting main plate 1 by the second fastener. In addition, the second fastener further connects the hinge mounting main plate 1 and the reinforcing structure 2, further improving the connection strength between the two, and further improving the strength and deformation resistance of the vehicle body frame 200.

[0180] In some embodiments, the hinge mounting main plate 1 is formed as an integrated stamping structure; and / or the reinforcing structure 2 is formed as an integrated stamping structure.

[0181] Optionally, the material of the hinge mounting main plate 1 can be, but is not limited to, carbon steel, stainless steel, aluminum-magnesium alloy, copper-zinc alloy, etc. The material of the reinforcing structure 2 can be, but is not limited to, carbon steel, stainless steel, aluminum-magnesium alloy, copper-zinc alloy, etc.

[0182] The integrated stamping structure is an integrated structure formed by stamping forming process. Such structure can reduce the welding points of parts, reduce the risk of quality defects, and improve production efficiency and consistency.

[0183] In some embodiments, the wall thickness of the hinge mounting main plate 1 is greater than or equal to 1.5 mm and less than or equal to 1.8 mm; the reinforcing structure 2 adopts a plate structure, and the wall thickness thereof is greater than or equal to 1.8 mm and less than or equal to 2.0 mm.

[0184] For example, the wall thickness of the hinge mounting main plate 1 can be, but is not limited to, 1.5 mm, 1.51 mm, 1.52 mm, 1.53 mm, 1.54 mm, 1.55 mm, 1.56 mm, 1.57 mm, 1.58 mm, 1.59 mm, 1.6 mm, 1.61 mm, 1.62 mm, 1.63 mm, 1.64 mm, 1.65 mm, 1.66 mm, 1.67 mm, 1.68 mm, 1.69 mm, 1.7 mm, 1.71 mm, 1.72 mm, 1.73 mm, 1.74 mm, 1.75 mm, 1.76 mm, 1.77 mm, 1.78 mm, 1.79 mm, 1.8 mm.

[0185] Exemplarily, the wall thickness of the reinforcing structure 2 can be, but is not limited to, 1.8 mm, 1.81 mm, 1.82 mm, 1.83 mm, 1.84 mm, 1.85 mm, 1.86 mm, 1.87 mm, 1.88 mm, 1.89 mm, 1.9 mm, 1.91 mm, 1.92 mm, 1.93 mm, 1.94 mm, 1.95 mm, 1.96 mm, 1.97 mm, 1.98 mm, 1.99 mm, 2 mm.

[0186] In this way, the thicknesses of the hinge mounting main plate 1 and the reinforcing structure 2 are set within an appropriate range, meeting the respective requirements for structural strength, and the space occupied and the mass are small.

[0187] In some embodiments, the material of the hinge mounting main plate 1 includes HC340 / 590DP steel material, and the material of the reinforcing structure 2 includes HC420 / 780DP steel material.

[0188] The HC340 / 590DP steel material is a high-strength steel cold-rolled dual-phase steel, with a yield strength of not less than 340 MPa and a tensile strength of not less than 590 MPa.

[0189] The HC420 / 780DP steel material is a high-strength steel cold-rolled dual-phase steel, with a yield strength of not less than 420 MPa and a tensile strength of not less than 780 MPa.

[0190] By using the above-mentioned materials, the hinge mounting main plate 1 and the reinforcing structure 2 have high strength, improving the strength and deformation resistance of the door hinge 40 mounting portion. Moreover, by using the material with relatively high yield strength and tensile strength for the reinforcing structure 2, the reinforcing structure 2 can better play a role in reinforcing the strength.

[0191] In some embodiments, as shown in FIG. 2, the reinforcing column 30 is configured as a pipe shell 310 with a closed cross section. Figure 8

[0192] It should be noted that the cross section refers to a cross section perpendicular to the extension direction of the reinforcing column 30.

[0193] The closed cross section means that, from the cross section of the pipe shell 310, the pipe wall is annular with the head connected to the tail. Here, the annular shape is not limited to a circular annular shape, and can be a triangular annular shape, a quadrilateral annular shape, a polygonal annular shape, an elliptical annular shape, an oblong annular shape, etc.

[0194] The pipe shell 310 can be hollow, or further structure can be arranged in the pipe cavity.

[0195] ​In one specific embodiment, a portion of the frame beam body 20 is recessed towards the vehicle body outer side b to form a first recess 210, the first recess 210 has an extending direction consistent with the extending direction of the reinforcing column 30, and further the inner contour size of the first recess 210 is greater than the outer contour size of the reinforcing column 30, so that the reinforcing column 30 can be located in the first recess 210.

[0196] Optionally, the tube shell 310 can be a composite pultruded tube beam, an aluminum alloy pultruded tube beam, or a hot gas expanded tube beam, etc.

[0197] Since the reinforcing column 30 is configured to have a closed cross-section tube shell 310, the closed cross-section tube reinforcing column 30 can effectively absorb impact energy, and has high strength and rigidity, improving the strength and deformation resistance of the vehicle body frame 200. Moreover, it is easy to process and install, which is conducive to improving the assembly efficiency of the vehicle 1000 and shortening the manufacturing cycle of the vehicle 1000.

[0198] In some embodiments, as shown in Figure 15 The reinforcing column 30 is configured to have a closed cross-section tube shell 310 and a reinforcing assembly 320 built-in the tube shell 310.

[0199] The reinforcing assembly 320 is used to further enhance the strength of the reinforcing column 30. For example, the reinforcing assembly 320 can include reinforcing ribs, reinforcing plates, or other structures that can be used to enhance the strength of the tube shell 310.

[0200] For example, reinforcing ribs are formed in the full length range of the tube shell 310, and the reinforcing ribs extend along the length direction of the tube shell 310.

[0201] For example, the cross-sectional shape of the tube shell 310 is polygonal, wherein the cross-section is perpendicular to the extending direction of the tube shell 310. In this way, the shell wall of the tube shell 310 is better connected with the frame beam body 20, and it is also helpful to increase the contact area between the shell wall of the tube shell 310 and the frame beam body 20, thereby helping to improve the structural strength and rigidity of the vehicle 1000.

[0202] It can be understood that the polygonal cross-section of the tube shell 310 can be a triangle, a quadrilateral, a pentagon, a hexagon, etc.

[0203] In this way, the strength and rigidity of the reinforcing column 30 can be further improved, and the strength and deformation resistance of the vehicle body frame 200 can be further improved.

[0204] In some embodiments, the reinforcing assembly 320 includes at least one first reinforcing rib 321 connected with the inner wall of the tube shell 310.

[0205] Exemplarily, in the cross section of the tube shell 310, opposite ends of the first reinforcing rib 321 are connected with the inner wall of the tube shell 310 respectively. By arranging the reinforcing rib in the tube shell 310, the structural strength and the structural rigidity of the reinforcing column 30 are further improved.

[0206] It can be understood that the number of the first reinforcing rib 321 is not limited in the embodiments of the present application, and can be set according to the performance requirements of the vehicle 1000.

[0207] In some embodiments, the number of the first reinforcing rib 321 is multiple, and at least part of the multiple first reinforcing ribs 321 are arranged in cross.

[0208] Since the first reinforcing rib 321 is connected with the inner wall of the tube shell 310, the space in the lumen of the tubular reinforcing column 30 can be effectively utilized, and the strength and the rigidity of the reinforcing column 30 can be improved without increasing the outer contour size of the reinforcing column 30, and the bending deformation is not easy to occur, thereby improving the strength and the deformation resistance of the vehicle body frame 200.

[0209] In some embodiments, the reinforcing column 30 is formed as an integrated roll-formed tube with a closed cross section.

[0210] The integrated roll-formed tube is an integrated tube structure formed by a roll forming process,

[0211] The reinforcing column 30 is an integrated roll-formed tube, on the one hand, the integral forming reduces the welding points, reduces the fatigue risk caused by the weld, prolongs the service life of the vehicle 1000, on the other hand, the roll forming process simplifies the production process, reduces the mold cost and the production cycle.

[0212] In some embodiments, the thickness of the tube wall of the reinforcing column 30 is greater than or equal to 1.8 mm and less than or equal to 2.2 mm.

[0213] Exemplarily, the thickness of the tube wall of the reinforcing column 30 can be, but is not limited to, 1.8 mm, 1.81 mm, 1.82 mm, 1.83 mm, 1.84 mm, 1.85 mm, 1.86 mm, 1.87 mm, 1.88 mm, 1.89 mm, 1.9 mm, 1.91 mm, 1.92 mm, 1.93 mm, 1.94 mm, 1.95 mm, 1.96 mm, 1.97 mm, 1.98 mm, 1.99 mm, 2 mm, 2.01 mm, 2.05 mm, 2.1 mm, 2.15 mm, 2.2 mm.

[0214] In this way, the thickness of the tube wall of the reinforcing column 30 is set in an appropriate range to meet the respective structural strength requirements, and the thickness is not too large to occupy a small space and have a light weight.

[0215] In some embodiments, the material of the reinforcement pillar 30 comprises QP1180 steel.

[0216] QP1180 steel is a high-strength steel, and the tensile strength of QP1180 steel is not less than 1180 MPa.

[0217] Therefore, the reinforcement pillar 30 is made of QP1180 steel, so that the reinforcement pillar 30 has high strength and can withstand large mechanical loads, thereby improving the tensile strength and crash energy absorption performance of the reinforcement pillar 30.

[0218] For example, the reinforcement pillar 30 is an integrated roll-formed tube with a closed cross-section and is made of QP1180 steel. The combination of QP1180 material and roll forming process significantly improves the tensile strength and crash energy absorption performance of the reinforcement pillar 30, while reducing the material thickness and weight.

[0219] In some embodiments, the reinforcement pillar 30 is formed as an integrated aluminum pultruded structure.

[0220] The aluminum pultruded tube structure is an aluminum tube produced by a pultrusion process, which has high strength and can withstand large mechanical loads. In addition, the aluminum pultruded tube has high stiffness and can reduce deformation under stress. Moreover, aluminum has a low density, which helps to reduce the weight of the vehicle 1000 compared to traditional steel bodies. The tube shell 310 and the first reinforcing rib 321 are an integrated structure, which on the one hand helps to improve the overall structural strength and stiffness of the reinforcement pillar 30, and on the other hand, with the first reinforcing rib 321 in the tube shell 310 of the reinforcement pillar 30, the first reinforcing rib 321 does not need to be assembled with other components, which helps to reduce manufacturing costs.

[0221] In some embodiments, the reinforcement pillar 30 is formed as a glass fiber reinforced composite pultruded tube.

[0222] Through pultrusion of glass fiber reinforced composite material, good strength and stiffness can be obtained, and a reinforcement pillar 30 with a complex cross-section can be obtained, which is beneficial to further optimize the mechanical properties and shape flexibility of the reinforcement pillar 30, and also beneficial to the lightweight of the vehicle body frame 200, and can improve the production efficiency of the reinforcement pillar 30.

[0223] In some embodiments, the reinforcement pillar 30 is formed as a tube shell 310 and a resin filling structure, and the resin filling structure is filled in the tube shell 310.

[0224] The resin filling structure is used to enhance the structural strength and stiffness of the tube shell 310, thereby further improving the strength and deformation resistance of the vehicle body frame 200.

[0225] In some embodiments, the tube shell 310 is a thermoplastic pultruded composite tube, and the resin filling structure includes polyurea and / or polyurethane.

[0226] For example, the composite material of the composite pultruded tube can be a composite material formed by combining a thermoplastic resin with continuous glass fibers, can be a composite material formed by combining a thermoplastic resin with continuous boron fibers, can be a composite material formed by combining a thermoplastic resin with ultra-high molecular weight polyethylene fibers, and can be other types of composite materials.

[0227] In some embodiments, the thermoplastic pultruded composite material can include a glass fiber reinforced composite material, the glass fiber reinforced composite material includes a thermoplastic resin matrix and continuous fibers, the continuous fibers include glass fibers, and the thermoplastic resin matrix can be a polypropylene (PP) resin matrix or a polyamide-6 (PA6) resin matrix. The same material as the glass fiber reinforced composite material used by the frame beam body 20 described below can also be used.

[0228] Polyurea and polyurethane have high toughness, which helps to improve the tensile strength of the reinforcing column 30, thereby further improving the strength and deformation resistance of the vehicle body frame 200.

[0229] In some embodiments, at least one second reinforcing rib (not shown) is arranged in the first groove 210 of the frame beam body 20.

[0230] Optionally, the second reinforcing rib can be one or more, and when the second reinforcing rib is multiple, the multiple second reinforcing ribs can be arranged substantially in parallel or can be arranged in a cross shape, wherein the distance between adjacent second reinforcing ribs can be equal or unequal.

[0231] In a specific embodiment, the frame beam body 20 is recessed in a direction away from the vehicle body inner side a to form the first groove 210, and the second reinforcing rib is arranged in the groove of the frame beam body 20, the second reinforcing rib forms a avoiding slot, and the reinforcing column 30 is at least partially arranged in the avoiding slot. In this way, the strength and rigidity of the frame beam body 20 can be improved, thereby improving the strength and rigidity of the vehicle body frame 200.

[0232] In some embodiments, no reinforcing rib can be arranged in the groove of the frame beam body 20.

[0233] In some embodiments, the number of second reinforcing ribs is multiple; the multiple second reinforcing ribs are arranged in a cross shape to form a mesh structure; and / or, the multiple second reinforcing ribs are connected end to end to form a ring structure.

[0234] In some embodiments, the reinforcing column 30 is connected with the bottom wall and the side wall of the first groove 210, and the second reinforcing rib is formed with a avoiding groove for installing the reinforcing column 30.

[0235] Therefore, the strength and rigidity of the frame beam body 20 are improved, and the strength and rigidity of the vehicle body frame 200 are improved.

[0236] In some embodiments, as shown in Figure 4 The number of the hinge mounting assemblies 10 is at least two groups, and the at least two hinge mounting assemblies 10 include at least one first hinge mounting assembly 10a and at least one second hinge mounting assembly 10b; the number of the door hinges 40 is at least two, and the at least two door hinges 40 include at least one upper door hinge 40a and at least one lower door hinge 40b, the upper door hinge 40a is connected to the upper part of the reinforcing column 30 through the first hinge mounting assembly 10a, and the lower door hinge 40b is connected to the lower part of the reinforcing column 30 through the second hinge mounting assembly 10b.

[0237] In some embodiments, as shown in Figure 4 In the door hinges 40, the upper door hinge 40 is the upper door hinge 40a, and the lower door hinge 40 is the lower door hinge 40b along the up-down direction e-f of the vehicle body.

[0238] The upper door hinge 40a and the lower door hinge 40b are used to connect the door 209 and the hinge mounting assembly 10, so that the door 209 is connected with the vehicle body frame 200, and the reinforcing column 30 can share the force acting on the upper door hinge 40a and the lower door hinge 40b. As shown in Figure 4 The reinforcing column 30 extends along the up-down direction e-f of the vehicle body, and the upper door hinge 40a and the lower door hinge 40b can be connected to the upper and lower ends of the reinforcing column 30, so that the upper door hinge 40a and the lower door hinge 40b can have a larger span, and the stability of the door installation can be further improved.

[0239] The materials, shapes and sizes of the upper door hinge 40a and the lower door hinge 40b can be the same or different.

[0240] The distance between the upper door hinge 40a and the lower door hinge 40b along the up-down direction e-f of the vehicle body can be increased as much as possible, so that the door 209 sagging load of the upper door hinge 40a and the lower door hinge 40b can be better dispersed to the reinforcing column 30. Since the upper door hinge 40a and the lower door hinge 40b are connected to the reinforcing column 30 to form an integrated structure, the reinforcing column 30 can share the force acting on the upper door hinge 40a and the lower door hinge 40b, thereby improving the overall structural rigidity, reducing the stress concentration at the hinge, and facilitating the reduction of deformation at the hinge, thereby improving the ability of the vehicle body frame 200 to resist deformation.

[0241] In some embodiments, as shown in Figs. 1 and 2, at least a portion of the frame rail body 20 forms at least one of the A-pillar 201, the B-pillar 202, and the C-pillar 203 of the vehicle 1000. Figure 2 Figure 3 As shown in Figs. 1 and 2, at least a portion of the frame rail body 20 forms at least one of the A-pillar 201, the B-pillar 202, and the C-pillar 203 of the vehicle 1000, and the first recess 210 is formed in at least a portion of the at least one of the A-pillar 201, the B-pillar 202, and the C-pillar 203, and the reinforcement pillar 30 is disposed in the first recess 210, and the door 209 is mounted to the reinforcement pillar 30 via the hinge mounting assembly 10 and the door hinge 40.

[0242] The reinforcement pillar 30 disposed in the first recess 210 of the at least one of the A-pillar 201, the B-pillar 202, and the C-pillar 203 can improve the structural strength and rigidity of the frame rail body 20, and improve the bending resistance and deformation resistance of the frame rail body 20, thereby improving the crashworthiness of the vehicle 1000.

[0243] Exemplarily, as shown in Figs. 1 and 2, the reinforcement pillar 30 is disposed in the first recess 210 of the A-pillar 201, and the reinforcement pillar 30 and the portion of the frame rail body 20 forming the A-pillar 201 jointly form at least a portion of an A-pillar assembly (also referred to as an A-pillar assembly). Figure 3 Exemplarily, as shown in Figs. 1 and 2, the reinforcement pillar 30 is disposed in the first recess 210 of the B-pillar 202, and the reinforcement pillar 30 and the portion of the frame rail body 20 forming the B-pillar 202 jointly form at least a portion of a B-pillar assembly (also referred to as a B-pillar assembly).

[0244] Figure 3 Exemplarily, as shown in Figs. 1 and 2, the reinforcement pillar 30 is disposed in the first recess 210 of the C-pillar 203, and the reinforcement pillar 30 and the portion of the frame rail body 20 forming the C-pillar 203 jointly form at least a portion of a C-pillar assembly (also referred to as a C-pillar assembly).

[0245] In some embodiments of the present application, as shown in Figs. 1 and 2, at least a portion of the frame rail body 20 forms the roof rail 204 and the rocker rail 205 of the vehicle 1000, and the portion of the frame rail body 20 forming the roof rail 204 and the rocker rail 205 is formed with a third recess 220 recessed toward a second side, and the third recess 220 of the roof rail 204 is filled with the first reinforcement beam 50, and the third recess 220 of the rocker rail 205 is filled with the second reinforcement beam 60, and one end of the reinforcement pillar 30 is connected to the first reinforcement beam 50 via the upper joint 70, and the other end of the reinforcement pillar 30 is connected to the second reinforcement beam 60 via the lower joint 80.

[0246] Exemplarily, as shown in Figs. 1 and 2, the reinforcement pillar 30 is disposed in the first recess 210 of the A-pillar 201, and the reinforcement pillar 30 and the portion of the frame rail body 20 forming the A-pillar 201 jointly form at least a portion of an A-pillar assembly (also referred to as an A-pillar assembly). Figure 3 Figure 4 Exemplarily, as shown in Figs. 1 and 2, the reinforcement pillar 30 is disposed in the first recess 210 of the B-pillar 202, and the reinforcement pillar 30 and the portion of the frame rail body 20 forming the B-pillar 202 jointly form at least a portion of a B-pillar assembly (also referred to as a B-pillar assembly).

[0247] ​​​Thus, the third recess 220 of the roof rail 204 and the rocker rail 205 is filled with the reinforcing beam, which improves the structural strength of the vehicle body frame 200. The connection of the reinforcing pillar 30 with the first reinforcing beam 50 and the second reinforcing beam 60 forms an integrated structure of the reinforcing pillar 30, the first reinforcing beam 50 and the second reinforcing beam 60, which can better improve the structural strength of the vehicle body frame 200 and further improve the ability of the vehicle body frame 200 to resist deformation.

[0248] For example, the upper joint 70 is connected to one end of the reinforcing pillar 30 by means of insertion, and the upper joint 70 is connected to the first reinforcing beam 50 by means of a fastener such as a bolt. The lower joint 80 is connected to the other end of the reinforcing pillar 30 by means of insertion, and the lower joint 80 is connected to the second reinforcing beam 60 by means of a fastener such as a bolt.

[0249] For example, as shown in Figure 3 The first reinforcing beam 50 is arranged in the third recess 220 of the roof rail 204, and the first reinforcing beam 50 and the frame rail body 20 form at least part of the roof rail assembly.

[0250] For example, as shown in Figure 3 The second reinforcing beam 60 is arranged in the third recess 220 of the rocker rail 205, and the second reinforcing beam 60 and the frame rail body 20 form at least part of the rocker rail assembly.

[0251] In some embodiments, the frame rail body 20 comprises a plurality of layers of continuous fiber composite material, each layer of continuous fiber composite material comprising continuous fibers and a thermoplastic resin matrix connecting the continuous fibers.

[0252] The composite material formed by the continuous fibers and the thermoplastic resin matrix has the characteristics of high strength, high rigidity and high toughness, which helps to improve the structural strength and structural rigidity of the frame rail body 20.

[0253] In some embodiments, the continuous fibers comprise one or more combinations of organic fibers and inorganic fibers. Organic fibers have high strength, good elasticity and flexibility. Inorganic fibers have high strength and modulus. The use of one or more combinations of organic fibers and inorganic fibers with the thermoplastic resin helps to improve the strength of the single-layer fiber composite material layer.

[0254] In some embodiments, the inorganic fibers comprise any one or any combination of glass fibers, aramid fibers or boron fibers.

[0255] In some embodiments, the organic fibers comprise any one or any combination of aromatic polyamide fibers and ultra-high molecular weight polyethylene fibers.

[0256] In some embodiments, the thermoplastic resin matrix comprises polyamide units, and a ratio of a number of carbons to a number of amide groups in the polyamide units is not less than 8. In this way, by controlling the ratio of the number of carbons to the number of amide groups in the individual structural units of the thermoplastic resin matrix, the number of CHx groups (methyl and methylene groups) in the individual polyamide units can be controlled, so that the strength of the single layer of the fiber composite material layer can be ensured, and the elongation at break of the single layer of the fiber composite material layer can be ensured, so that the fiber composite material layer can meet the requirements of high strength and high elongation at break.

[0257] Exemplarily, the polyamide comprises any one or a combination of PA610, PA11, PA12, PA1212, PA1012, and PA1313.

[0258] Thus, the composite material formed by the continuous fibers and the thermoplastic resin matrix has the characteristics of high strength, high rigidity, and high toughness, which helps to improve the structural strength and the structural rigidity of the frame beam body 20.

[0259] In other embodiments, the thermoplastic resin matrix can be a polypropylene (which can be denoted as PP) resin matrix.

[0260] In some embodiments, the continuous fibers are continuous glass fibers or continuous carbon fibers.

[0261] The glass fiber reinforced composite material has low density, high strength, good corrosion resistance, and design flexibility, and thus can prolong the service life of the frame beam body 20, thereby prolonging the service life of the vehicle 1000, and further improving the structural strength and rigidity of the vehicle 1000 and the lightweight degree of the vehicle 1000. The continuous carbon fiber has the advantages of high strength, high modulus, lightweight, high temperature resistance, impact resistance, and fatigue resistance, and thus can prolong the service life of the frame beam body 20, thereby prolonging the service life of the vehicle 1000, and further improving the structural strength and rigidity of the vehicle 1000 and the lightweight degree of the vehicle 1000.

[0262] Hereinafter, specific examples of some embodiments of the present application will be described with reference to the accompanying drawings.

[0263] As a specific example, a vehicle 1000 is provided, the B-pillar assembly of the vehicle 1000 includes a B-pillar 202 made of continuous fiber composite material and a B-pillar reinforcing pipe (reinforcing column 30) arranged in the first groove 210 of the B-pillar 202, the B-pillar reinforcing pipe is made of QP1180 material, the thickness of the pipe wall is 2.2mm, and is processed by a roll forming process, has excellent tensile strength and crash energy absorption performance, and also reduces the thickness and weight of the B-pillar reinforcing pipe, and the roll forming process simplifies the production process, greatly reduces the mold cost and production cycle, and is suitable for efficient mass production. The B-pillar reinforcing pipe is provided with a lower door hinge mounting assembly (second hinge mounting assembly 10b), and the lower door hinge mounting assembly 10 includes a lower door hinge mounting plate (hinge mounting main plate 1) and a reinforcing plate (reinforcing structure 2) connected to each other, the material of the lower door hinge mounting plate is HC340 / 590DP, and the material of the reinforcing plate is HC420 / 780DP, which improves the structural strength and crash safety of the hinge mounting area.
