TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a vehicle. BACKGROUND

[0002] The vehicle usually comprises a body frame which plays an important role in improving the overall rigidity and strength of the vehicle body. However, the body frame, while playing a protective role for the passengers in the vehicle, will also hinder the driver's view to some extent, resulting in a blind area. Therefore, how to reduce the impact of the body frame of the vehicle on the driver's view while meeting the strength and rigidity requirements of the vehicle has become one of the problems in the industry. CONTENT OF THE UTILITY MODEL

[0003] To solve the above technical problems, the embodiments of the present application provide a vehicle which can reduce the impact of the body frame of the vehicle on the driver's view while meeting the strength and rigidity requirements of the vehicle.

[0004] The embodiments of the present application are implemented by the following technical solutions.

[0005] The first aspect of the present application provides a vehicle, which comprises a body frame, and the body frame comprises: a frame beam body made of a fiber composite plate, one side of the frame beam body facing the inner side of the vehicle body, the other side of the frame beam body facing the outer side of the vehicle body, and the frame beam body having a recessed groove recessed in a direction away from the inner side of the vehicle body; an inner plate connected to the side of the frame beam body facing the inner side of the vehicle body, covering the recessed groove, and forming a cavity together with the frame beam body; and a reinforcing structure arranged in the cavity and connected between the frame beam body and the inner plate; wherein the frame beam body comprises a plurality of outer plates connected and arranged, and the positions of the frame beam body forming the recessed groove have a plurality of bending parts, and at least two bending parts are formed by different outer plates.

[0006] Since the frame beam body comprises a plurality of outer plates connected and arranged, and at least two bending parts are formed by different outer plates, when the reinforcing structure is connected to the frame beam body, the reinforcing structure can be connected to the outer plates in a state that the plurality of outer plates are separated, the operation space is increased, the assembly difficulty of the body frame is reduced, and the space between the reinforcing structure and the outer plates can be easily reduced. The assembly of the frame beam body and the reinforcing structure can be realized while reducing the size of the inner cavity, so that the impact of the body frame of the vehicle on the driver's view can be reduced while meeting the strength and rigidity requirements of the vehicle. Moreover, since the reinforcing structure is arranged in the cavity and connected between the frame beam body and the inner plate, the bending resistance of the body frame can be improved to meet the requirements of 25% offset collision of the vehicle. In addition, since the frame beam body is made of a fiber composite plate, the light weight of the frame beam body and even the vehicle can be improved while meeting the strength and rigidity requirements of the frame beam body.

[0007] In some embodiments, the plurality of outer plates includes a first outer plate formed with a first bent portion and a second outer plate formed with a second bent portion, and a portion of the first outer plate overlaps with a portion of the second outer plate and is adhesively connected to each other.

[0008] Thus, the first outer plate and the second outer plate can be adhesively formed into the frame beam body, and the structure is simple, and there is no welding mark or metal part drying deformation affecting the flatness or aesthetics of the frame beam body. Moreover, the frame beam body includes the first outer plate formed with the first bent portion and the second outer plate formed with the second bent portion, so that the frame beam body can be disassembled, and the connection of the first outer plate and the reinforcing structure and the connection of the first outer plate and the second outer plate can be respectively performed in a state that the first outer plate and the second outer plate are separated, so as to reduce the probability of interference between the frame beam body and the reinforcing structure during assembly, and the reinforcing structure can occupy most of the cavity, and the space utilization of the cavity can be improved. In addition, since a portion of the first outer plate overlaps with a portion of the second outer plate, the adhesively connected first outer plate and the second outer plate can be conveniently connected, and the strength and rigidity of the vehicle body frame can be improved, thereby improving the strength and rigidity of the vehicle body as a whole.

[0009] In some embodiments, the frame beam body is adhesively connected to the inner plate.

[0010] Thus, the frame beam body and the inner plate can form a sealed cavity, improve the strength of the vehicle, and the adhesively connected connection is convenient to operate.

[0011] In some embodiments, a portion of the reinforcing structure towards the outside of the vehicle body is adhesively connected to a portion of the recessed groove towards the inside of the vehicle body.

[0012] Thus, the relative position of the reinforcing structure and the frame beam body can be fixed and integrated by adhesively connecting, which is conducive to improving the strength and rigidity of the frame beam body and the inner plate, thereby improving the strength and rigidity of the vehicle.

[0013] In some embodiments, the first outer plate includes a first plate segment and a second plate segment forming the first bent portion, the second outer plate includes a third plate segment and a fourth plate segment forming the second bent portion, the first outer plate and the second outer plate are connected in a manner that the first plate segment is closer to the inside of the vehicle body than the third plate segment, and the second plate segment is closer to the front side of the vehicle body than the fourth plate segment; along a direction from the outside of the vehicle body towards the inside of the vehicle body, the third plate segment, the first plate segment, and the reinforcing structure are sequentially overlapped and adhesively connected, and along a front-rear direction of the vehicle body, the reinforcing structure is located between the second plate segment and the fourth plate segment.

[0014] Thus, the recessed groove surrounding the reinforcing structure from the front side of the vehicle body, the outside of the vehicle body, and the rear side of the vehicle body can be formed by the first outer plate and the second outer plate, the structure is simple and easy to assemble, and the adhesion and assembly with the reinforcing structure are facilitated.

[0015] In some embodiments, the first outer plate further comprises a fifth plate segment, and the first plate segment, the second plate segment and the fifth plate segment are sequentially connected; the second outer plate further comprises a sixth plate segment, and the third plate segment, the fourth plate segment and the sixth plate segment are sequentially connected; and the inner plate is adhesively connected with the fifth plate segment and the sixth plate segment.

[0016] The outer plate and the inner plate can be adhesively connected easily, and a cavity for accommodating the reinforcing structure can be formed.

[0017] In some embodiments, the reinforcing structure is configured as a tubular reinforcing structure with a closed cross section.

[0018] The tubular reinforcing structure with a closed cross section can effectively absorb impact energy, has high strength and rigidity, has good bending resistance, and is easy to process and install, which is beneficial to improving the assembly efficiency of the vehicle and shortening the manufacturing cycle of the vehicle.

[0019] In some embodiments, a pipe wall of the tubular reinforcing structure facing the outside of the vehicle body is adhesively connected with the frame beam body, and a pipe wall of the tubular reinforcing structure facing the inside of the vehicle body is adhesively connected with the inner plate.

[0020] In this way, the space in the cavity can be used more effectively, the outer contour size of the vehicle body frame can be reduced, the influence of the vehicle body frame of the vehicle on the driver's field of view can be reduced, and the adhesively connecting operation is simple.

[0021] In some embodiments, the inner plate has a protruding rib portion protruding toward the outside of the vehicle body, and the pipe wall of the tubular reinforcing structure facing the inside of the vehicle body is adhesively connected with the protruding rib portion.

[0022] Since the inner plate has the protruding rib portion protruding toward the outside of the vehicle body, the deformation resistance of the inner plate can be improved, and the support capacity for the reinforcing structure can also be improved, which is beneficial to improving the bending resistance of the vehicle as a whole.

[0023] In some embodiments, the tubular reinforcing structure is a glass fiber reinforced composite material pultruded pipe, and the thickness of the pipe wall of the tubular reinforcing structure is 6mm-10mm; or the tubular reinforcing structure is an aluminum alloy pultruded pipe, and the thickness of the pipe wall of the tubular reinforcing structure is 3mm-5mm.

[0024] In this way, the strength, rigidity performance and weight as well as the outer shape size of the reinforcing structure can be considered.

[0025] In some embodiments, the tubular reinforcing structure is internally provided with a reinforcing assembly.

[0026] In this way, the strength of the reinforcing structure can be further improved, so as to improve the strength of the vehicle.

[0027] In some embodiments, the reinforcing assembly comprises at least one reinforcing rib, and each reinforcing rib is connected with the pipe wall of the tubular reinforcing structure and located in the pipe cavity.

[0028] Since the reinforcing rib is connected to the pipe wall of the tubular reinforcing structure and located in the pipe cavity, the space in the pipe cavity of the tubular reinforcing structure can be effectively utilized, and the strength of the tubular reinforcing structure can be enhanced without increasing the outer contour size of the tubular reinforcing structure, thereby enhancing the strength of the reinforcing structure and further increasing the strength of the vehicle.

[0029] In some embodiments, the reinforcing ribs are formed in the full length range of the tubular reinforcing structure and extend along the length direction of the tubular reinforcing structure.

[0030] Therefore, the bending resistance of the reinforcing structure can be further improved.

[0031] In some embodiments, the reinforcing assembly includes a first reinforcing rib and a second reinforcing rib, and the first reinforcing rib and the second reinforcing rib are connected to each other in cross section of the tubular reinforcing structure.

[0032] Therefore, the bending resistance of the reinforcing structure can be further improved, and the bending resistance in multiple directions can be improved.

[0033] In some embodiments, the pipe wall of the tubular reinforcing structure includes a first pipe wall, a second pipe wall, a third pipe wall and a fourth pipe wall connected end to end, wherein the first pipe wall and the third pipe wall are oppositely arranged, the second pipe wall and the fourth pipe wall are oppositely arranged, the first reinforcing rib is connected to the first pipe wall and the third pipe wall respectively, and the second reinforcing rib is connected to the second pipe wall and the fourth pipe wall respectively.

[0034] Therefore, the tubular reinforcing structure with a closed cross section in the shape of a quadrilateral can be formed, which is beneficial to improve the bending resistance and has a simple configuration and is easy to manufacture.

[0035] In some embodiments, the vehicle body frame includes a vehicle body pillar assembly, a side beam assembly, a cross beam assembly and a rocker beam assembly; the frame beam body includes a vehicle body pillar, a side beam, a cross beam and a rocker beam, and the frame beam body, the reinforcing structure and the inner plate collectively form at least part of the vehicle body pillar assembly and / or at least part of the side beam assembly and / or at least part of the cross beam assembly and / or at least part of the rocker beam assembly.

[0036] Therefore, the strength and rigidity of the vehicle body pillar and the beam member can be enhanced, the bending resistance of the vehicle body frame during a collision can be improved, and the space occupied by the vehicle body pillar and the beam member can be reduced.

[0037] In some embodiments, along the front-rear direction of the vehicle body, the vehicle body pillar includes at least one of a front pillar, a middle pillar and a rear pillar; and the vehicle body pillar assembly includes at least one of a front pillar assembly, a middle pillar assembly and a rear pillar assembly.

[0038] The above structure can be applied to any one of the front pillar, the middle pillar and the rear pillar, thus on the one hand, the strength and rigidity of the entire vehicle body are improved, and on the other hand, the space occupied by each vehicle body pillar is reduced, the passenger space is increased, and the overall lightweight degree of the vehicle body is improved.

[0039] In some embodiments, the frame beam body, the reinforcing structure and the inner plate collectively form at least a portion of the front pillar assembly.

[0040] Thus, the strength and rigidity of the front pillar are enhanced, the performance of the vehicle in a 25% offset collision is improved, and the impact of the front pillar on the driver's field of view is reduced.

[0041] In some embodiments, the front pillar assembly includes a front pillar assembly upper member and a front pillar assembly lower member connected to each other, the front pillar assembly upper member is connected to the side sill and the front pillar assembly lower member, and the frame beam body, the reinforcing structure and the inner plate collectively form the front pillar assembly upper member.

[0042] Thus, the bending resistance of the front pillar assembly upper member of the vehicle body is improved, the range of the driver's field of view is less affected, and a comfortable large field of view is provided for the driver.

[0043] In some embodiments, the vehicle further includes a chassis, the vehicle body frame is mounted to the chassis and collectively forms a passenger compartment, the vehicle body frame includes a vehicle body pillar assembly, and the frame beam body, the reinforcing structure and the inner plate collectively form at least a portion of the vehicle body pillar assembly.

[0044] Thus, the strength and rigidity of the vehicle body pillar assembly are improved, and the impact of the vehicle body pillar assembly on the driver's field of view is reduced.

[0045] In some embodiments, the vehicle further includes a battery device, and the battery device is mounted to the chassis.

[0046] Thus, on the one hand, the vehicle has excellent strength and rigidity performance, is lightweight, and does not easily affect the driver's field of view, and on the other hand, the space utilization rate of the vehicle bottom is improved, the space occupied by the battery device in the passenger compartment and the trunk is reduced, and a more spacious seating and storage space is provided. Moreover, the installation of the battery device on the chassis can reduce the direct impact of the vehicle collision on the passenger. In addition, the centralized installation of the battery device on the chassis facilitates maintenance and replacement, and reduces the complexity of daily maintenance.

[0047] In some embodiments, the shell of the battery device forms at least a portion of the floor of the passenger compartment.

[0048] Thus, the redundancy of the vehicle can be reduced, thereby reducing the overall weight. Moreover, the packaging space of the battery module can be increased, the internal layout of the vehicle is optimized, and the space utilization rate is improved.

[0076] The vehicle generally comprises a body frame which plays an important role in improving the overall rigidity and strength of the vehicle body. However, the body frame, while playing a role in protecting the occupant inside the vehicle, will also hinder the driver's view to some extent, resulting in a blind area. Therefore, how to reduce the impact of the body frame of the vehicle on the driver's view while meeting the strength and rigidity requirements of the vehicle has become one of the technical problems in the industry.

[0077] To solve the above technical problems, the embodiments of the present application provide a vehicle.

[0078] In the following, the vehicle related to the embodiments of the present application will be described. Figures 1 to 3 The vehicle related to the embodiments of the present application will be described. Figure 1 The structural exploded view of the vehicle provided for some embodiments of the present application is shown in the figure; Figure 2 The exploded view of the vehicle provided for some embodiments of the present application is shown in the figure; Figure 3 The structural view of the electric vehicle provided for some embodiments of the present application is shown in the figure.

[0079] As shown in the figure, Figure 1 The vehicle 1000 of the embodiments of the present application comprises a chassis 30 and a vehicle body 100 arranged on the chassis 30, and the vehicle body 100 at least partially adopts the vehicle body frame provided by the embodiments of the present application.

[0080] The vehicle body 100 is used to form the vehicle body appearance and the passenger compartment 20 and protect the occupant in the passenger compartment 20. The chassis 30 is located below the vehicle body 100 and is used to carry the engine, the battery device and other components. The wheels 40, Figure 1 A four-wheeled vehicle is shown in the figure.

[0081] As shown in the figure, Figure 2 The vehicle body 100 comprises a vehicle body frame 10 and a vehicle body cover 11, the vehicle body frame 10 is used to form the vehicle body skeleton and plays a supporting and protecting role; the vehicle body cover 11 is connected to the vehicle body frame 10 and is used to form a closed interior space and a vehicle body appearance. The vehicle body frame 10 and the chassis 30 are connected to each other. In some embodiments, the vehicle body frame 10 and the chassis 30 are welded together; in other embodiments, the vehicle body frame 10 and the chassis 30 are connected in a detachable manner by fasteners. Optionally, the fasteners can include at least one of bolts, studs and screws. The number of fasteners can be multiple.

[0082] In some embodiments, the vehicle body frame 10 and the chassis 30 jointly enclose the passenger compartment 20 of the vehicle, and the vehicle comprises a battery device 200 (see Figure 3The battery pack housing forms at least a portion of the floor 31 of the passenger compartment 20. Integrating the battery pack into the chassis reduces additional supports and connectors, helps reduce overall vehicle weight, and minimizes the space occupied by the battery pack within the vehicle's interior.

[0083] For example, the vehicle frame 10 is connected to the chassis 30 in a detachable manner, for instance, by using multiple bolts to achieve a detachable connection in the circumferential direction of both the chassis 30 and the vehicle frame 10. Additionally, the chassis 30 may incorporate an integrated motor system (including...) Figure 3 The motor 300 shown), battery system (including) Figure 3 The battery device 200 shown) and the electronic control system (including Figure 3 The controller 400 (also known as the "three-electric system") is mounted on a skateboard chassis. This structure allows for the separation and decoupling of the vehicle frame 10 and chassis 30, enabling the vehicle frame 10 to be replaced as needed, shortening the development cycle and reducing costs. In other words, it increases the integration of chassis 30, making it adaptable to various vehicle models.

[0084] The vehicles involved in the embodiments of this application can be gasoline-powered vehicles, natural gas-powered vehicles, or new energy vehicles. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The vehicles can also be front-wheel drive vehicles, rear-wheel drive vehicles, or four-wheel drive vehicles.

[0085] The following descriptions will use the combination of the vehicle frame 10 and the skateboard chassis as an example.

[0086] like Figure 1 As shown, the vehicle frame 10 involved in this application embodiment includes at least structural components such as vehicle pillar assembly 101, crossbeam assembly 102, side beam assembly 103, and sill beam assembly 104. The vehicle body panel 11 includes at least hood 111, side fenders 112, and side doors 113, and may also include tailgate 114, anti-collision beam (not shown in the figure), bumper (not shown in the figure), and roof (not shown in the figure). The vehicle pillar assembly 101 is a collective term for the front pillar assembly (also known as the "A-pillar assembly") 1011, the middle pillar assembly (also known as the "B-pillar assembly") 1012, and the rear pillar assembly (also known as the "C-pillar assembly") 1013. Based on the context, it can be understood as a collection of the front pillar assembly 1011, the middle pillar assembly 1012, and the rear pillar assembly 1013, or at least any one of the front pillar assembly 1011, the middle pillar assembly 1012, and the rear pillar assembly 1013.

[0087] Optionally, the front pillar assembly can be located on both sides of the windshield to fix the windshield; the front pillar assembly can also be connected between the side beam assembly 103 and the sill beam assembly 104 to provide support and protection and to transfer collision loads.

[0088] In some embodiments, the front pillar assembly 1011 includes a front pillar assembly upper member 1011a and a front pillar assembly lower member 1011b connected together. Optionally, the front pillar assembly can include the front pillar assembly upper member 1011a mainly located on both sides of the front windshield and the front pillar assembly lower member 1011b mainly located on the front side of the side doors 113 on both sides, and further include a joint (not shown in the figure) connecting the front pillar assembly upper member 1011a and the front pillar assembly lower member 1011b together.

[0089] The vehicle body 100 at least partially adopts the vehicle body frame of the vehicle provided in the embodiments of the present application, which means that the vehicle body frame of the vehicle provided in the embodiments of the present application can be applied to a part or several parts of the vehicle body 100 according to the actual situation of the vehicle. For example, the vehicle body frame of the vehicle provided in the embodiments of the present application can be applied to at least any one of the front pillar assembly upper member 1011a and the front pillar assembly lower member 1011b.

[0090] In some embodiments, the frame beam body 1 of the vehicle body frame 10 is made of fiber-reinforced composite material, which means that most of the structure of the frame beam body 1 is made of fiber-reinforced composite material.

[0091] In the prior art, a metal plate is usually welded to form a vehicle body pillar assembly and other vehicle body frames. Such a vehicle body frame usually includes an outer plate, an inner plate and an intermediate plate body, the outer plate and the inner plate are welded to form a reinforcing cavity, and the intermediate plate body is located in the reinforcing cavity. When manufacturing such a structure, clamping tools and the like need to be inserted into the reinforcing cavity, so a large space needs to be reserved in the reinforcing cavity for clamping tools and the like, and there is a problem that it is difficult to reduce the profile size of the outer plate. When the front pillar assembly of the vehicle body adopts such a structure, for example, the outer profile of the front pillar assembly is easy to intrude into the field of view of the driver, thereby forming a large field of view blind area, which is not conducive to providing a wide field of view for the driver.

[0092] It is found that the outer contour size of the vehicle body pillar assembly can be reduced if the space of the reinforcing cavity is reduced. Therefore, the embodiments of the present application solve the problem of needing to reserve a large space for clamping tools and the like in the reinforcing cavity by assembling the frame beam body into two or more outer plates. Specifically, the recessed groove is formed by providing the plurality of outer plates with a plurality of bending portions. Since the recessed groove is formed by the plurality of outer plates, the connection between the reinforcing structure and the frame beam body can be achieved in a state where the plurality of outer plates are separated from each other, without the need to reserve space for clamping tools and the like, thereby reducing the outer contour size of the vehicle body pillar assembly. Moreover, for the frame beam body, the fiber composite plate material is used instead of the traditional metal material, which not only helps to achieve lightweight and efficient manufacturing of the vehicle body, but also solves the problems of welding marks, limited welding operation space, difficulty in bonding between metal plate parts, and deformation of the bonded parts during baking.

[0093] Based on such a design concept, the embodiments of the present application provide a vehicle, which comprises a vehicle body frame, the vehicle body frame comprising: a frame beam body made of a fiber composite plate, the frame beam body having a recessed groove recessed in a direction away from the inner side of the vehicle body; an inner plate connected to the frame beam body, covering the recessed groove, and forming a cavity together with the frame beam body; a reinforcing structure arranged in the cavity and connected between the frame beam body and the inner plate; wherein the frame beam body comprises a plurality of connected outer plates, the position of the frame beam body forming the recessed groove has a plurality of bending portions, and at least two bending portions are formed by different outer plates.

[0094] Since the frame beam body comprises a plurality of connected outer plates, and at least two bending portions are formed by different outer plates, when the reinforcing structure is connected to the frame beam body, the reinforcing structure can be connected to the outer plates in a state where the plurality of outer plates are separated, which increases the operation space, reduces the assembly difficulty of the vehicle, and can easily reduce the space between the reinforcing structure and the outer plates, thereby achieving the assembly of the frame beam body and the reinforcing structure while reducing the size of the inner cavity, so as to reduce the influence of the vehicle body frame on the driver's field of view while meeting the strength and rigidity requirements of the vehicle. Moreover, since the reinforcing structure is arranged in the cavity and connected between the frame beam body and the inner plate, the bending resistance of the vehicle body frame can be improved to meet the 25% offset collision requirement of the vehicle. In addition, since the frame beam body is made of a fiber composite plate, the lightweight degree of the frame beam body and even the vehicle body can be improved while meeting the strength and rigidity requirements of the frame beam body.

[0095] Hereinafter, the vehicle provided by some embodiments of the present application will be described in detail with reference to the accompanying drawings. Figures 1 to 9 The vehicle provided by some embodiments of the present application will be described in detail.

In addition, sometimes the side facing the passenger compartment 20 is referred to as the inner side of the vehicle body, and the side facing away from the passenger compartment 20 towards the outside of the vehicle is referred to as the outer side of the vehicle body.

[0098] As shown in Figure 1 and Figure 2 , the vehicle provided by the embodiments of the present application includes a vehicle body frame 10, as shown in Figure 4 , Figures 7 to 9 , the vehicle body frame 10 includes a frame beam body 1, an inner plate 2, and a reinforcing structure 4. The frame beam body 1 is made of a fiber composite plate. The frame beam body 1 has a recessed groove 13 recessed in the direction away from the inner side of the vehicle body. The inner plate 2 is connected with the frame beam body 1, covers the recessed groove 13, and forms a cavity 3 together with the frame beam body 1. The reinforcing structure 4 is arranged in the cavity 3 and connected between the frame beam body 1 and the inner plate 2. As shown in Figure 5 and Figure 6 , the frame beam body 1 includes a plurality of outer plates 14 arranged in connection, the position of the frame beam body 1 forming the recessed groove 13 has a plurality of bending parts 15, and at least two bending parts 15 are formed by different outer plates 14.

[0099] The frame beam body 1 can cover the reinforcing structure 4 from the outer side of the vehicle body, and the inner plate 2 can cover the reinforcing structure 4 from the inner side of the vehicle body.

[0100] In some embodiments, the frame beam body 1 is made of fiber composite material. Optionally, the inner panel 2 may also be made of fiber composite material. The material of the inner panel 2 may be the same as that of the frame beam body 1, or it may be different, for example, using different fiber composite materials. In some embodiments, the fiber composite material may be a fiber-reinforced resin composite material.

[0101] like Figures 5 to 9 As shown, the frame beam body 1 has a recessed groove 13 formed in a direction opposite to the inner side of the vehicle body. The shape of the recessed groove 13 is not specifically limited in this application. In some embodiments, the cross-section of the recessed groove 13 can be formed to resemble the outer contour shape of the reinforcing structure 4. Part or all of the reinforcing structure 4 can be accommodated in the recessed groove 13. In a specific embodiment, such as... Figure 5 As shown, the cross-section of the recessed groove 13 is generally U-shaped. The shape of the recessed groove 13 in its extending direction is adapted to the shape of the vehicle body frame (e.g., the front pillar). The following description uses the case where the vehicle body frame is adapted to the member 1011a of the front pillar assembly as an example. However, the vehicle body frame provided in this embodiment can also be adapted to other parts of the body frame 10.

[0102] like Figures 7 to 9 As shown, the inner plate 2 is connected to the frame beam body 1, and the inner plate 2 can cover the recessed groove 13 formed by the frame beam body 1. The inner plate 2 and the frame beam body 1 together form a cavity 3.

[0103] In some embodiments, the two ends of the inner panel 2 are connected to the two ends of the frame beam body 1. Regarding the connection method, adhesive bonding may be used, but other connection methods suitable for fiber composite panels can also be employed.

[0104] Optionally, the cross-sectional shape of the cavity 3 can be circular, rectangular, or other shapes. In some embodiments, the cross-sectional shape of the cavity 3 is substantially similar to the outer contour shape of the reinforcing structure 4. For example, the shape of the outer contour of the reinforcing structure 4 is substantially the same as the shape of the inner contour of the cavity 3 enclosed by the inner panel 2 and the outer panel 14. In a specific embodiment, the cross-section of the reinforcing structure 4 is quadrilateral, and the cross-sectional shape of the cavity 3 is also substantially quadrilateral. Regarding the size of the cavity 3, from a cross-sectional perspective, it only needs to be able to accommodate the reinforcing structure 4, and the outer contour of the reinforcing structure 4 can be close to or in contact with the outer panel 14 and / or the inner panel 2. Optionally, along the front-rear direction of the vehicle body, the front portion of the cross-section can be narrower than the rear portion, which helps to further reduce obstruction of the driver's view.

[0105] like Figures 6 to 9As shown, the reinforcing structure 4 is used to increase the strength and rigidity of part or whole of the vehicle body frame 10 to improve the bending resistance. The reinforcing structure 4 can be a reinforcing rib assembly or a tubular reinforcing structure 42 or a combination of the tubular reinforcing structure 42 and reinforcing ribs, of course, the reinforcing structure 4 can also be other suitable structures. The tubular reinforcing structure 42 can be a tubular reinforcing structure with a closed cross section or a tubular reinforcing structure with other cross section shapes.

[0106] In some embodiments, as shown, the reinforcing structure 4 is located between the frame beam body 1 and the inner plate 2, and the reinforcing structure 4 can be connected with at least one of the frame beam body 1 and the inner plate 2, in a specific embodiment, the reinforcing structure 4 is connected with both the frame beam body 1 and the inner plate 2. Figures 7 to 9

[0107] In some embodiments, as shown, the frame beam body 1 includes a plurality of outer plates 14 arranged in connection. Optionally, from the cross section of a certain beam member of the frame beam body 1 (for example, the A-A cross section shown in Figures 5 to 9 Figure 2 In some embodiments, as shown, the frame beam body 1 includes a plurality of outer plates 14 arranged in connection. Optionally, from the cross section of a certain beam member of the frame beam body 1 (for example, the A-A cross section shown in

[0108] In some embodiments, as shown, the frame beam body 1 has a plurality of bending portions 15 at the position where the recessed groove 13 is formed, for example, the bending portion 15 can have two, three or four, etc. In the case of a polygonal cross-sectional shape of the recessed groove 13, more bending portions 15 can be designed according to the number of sides. Figure 5 Figure 6 In some embodiments, at least two bending portions 15 are formed by different outer plates 14. In a specific embodiment, as shown in

[0109] In some embodiments, at least two bending portions 15 are formed by different outer plates 14. In a specific embodiment, as shown in Figure 5 Figure 6 In some embodiments, at least two bending portions 15 are formed by different outer plates 14. In a specific embodiment, as shown in Figure 6 ​​​​As shown, one of the outer plates 14 (first outer plate 141) with a bend 15 can be connected to the reinforcing structure 4, and another outer plate 14 (second outer plate 142) with a bend 15 can be connected to the side of the first outer plate 141 facing away from the reinforcing structure 4. The assembly of the outer plate 14 and the reinforcing structure 4 is then connected to the inner plate 2. Thus, since the first outer plate 141 and the second outer plate 142 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 structure 4 to the outer plate 14 and the inner plate 2. This reduces the assembly difficulty of the vehicle frame 10 and allows for easier reduction of the space between the reinforcing structure and the outer plate, enabling the assembly of the frame beam body 1 and the reinforcing structure 4 while reducing the internal cavity size. Therefore, while meeting the vehicle's strength and rigidity requirements, the impact of the vehicle frame on the driver's visibility can be reduced.

[0110] Because the main frame beam 1 is made of fiber composite board, its strength and weight reduction are both improved, thus enhancing both the strength and weight reduction of the vehicle body frame 10. Furthermore, since the reinforcing structure 4 is located within the cavity 3 and connects the main frame beam 1 and the inner panel 2, it allows for more efficient use of the cavity 3's space, improving the bending resistance of the vehicle body frame 10 and meeting or even enhancing its performance in 25% offset collisions.

[0111] The 25% offset collision test for vehicles refers to the 25% overlap offset frontal collision test. This test is one of the indicators for testing vehicle safety performance. It simulates the offset collision situation of a vehicle on the road. Here, 25% means that the overlap rate between the vehicle and the barrier in front is 25%. When the vehicle collides with the deformable barrier, the width of the overlap portion is within the range of 25% ± 20 mm of the vehicle width.

[0112] The test can be conducted as follows: the vehicle impacts a rigid barrier 1.5 meters high at a speed of 64±1 km / h. During this process, the deformation of the front pillar (front pillar assembly 1011), steering column, and pedals is monitored. To more realistically simulate actual collision conditions, a 50th percentile male Hybrid III dummy is also placed in the front driver's seat during the test.

[0113] In some embodiments, such as Figure 5 and Figure 6 As shown, the plurality of outer panels 14 include a first outer panel 141 having a first bend 151 and a second outer panel 142 having a second bend 152, wherein a portion of the first outer panel 141 overlaps with a portion of the second outer panel 142 and is bonded to each other.

[0114] The first outer plate 141 and the second outer plate 142 can each be an integral plate. The first outer plate 141 has at least one bend; the second outer plate 142 has at least one bend. The first outer plate 141 and the second outer plate 142 are joined together in a partially overlapping manner, and at least two of these bends 15 form the corner of the recessed groove 13.

[0115] In one specific embodiment, the first outer plate 141 is an integrally formed part, and the first outer plate 141 is molded to form a first bent portion 151, wherein the angle formed by the first bent portion 151 can be in the range of 60° to 120°, and further, the angle formed by the first bent portion 151 can be in the range of 80° to 100°.

[0116] In one specific embodiment, the second outer plate 142 is an integrally formed part, and the second outer plate 142 is molded to form a second bent portion 152. The angle formed by the second bent portion 152 can be in the range of 60° to 120°, and further, the angle formed by the second bent portion 152 can be in the range of 80° to 100°.

[0117] In some embodiments, such as Figure 5 and Figure 6 As shown, the first outer panel 141 and the second outer panel 142 have overlapping portions, which can be bonded together. The overlapping portions can be the parts of the first outer panel 141 and the second outer panel 142 that are close to each other along the front-rear direction of the vehicle body. In the bonded state, the overlapping portions are located between the first bend 151 and the second bend 152, forming the bottom of the recessed groove 13.

[0118] In some embodiments, the first outer panel 141 and the second outer panel 142 are both fiber composite boards. Thus, the first outer panel 141 and the second outer panel 142 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 the bonding and baking of metal parts.

[0119] Thus, the first outer plate 141 and the second outer plate 142 can be bonded to form the frame beam body 1, and the structure is simple, and there is no welding mark or metal part drying deformation and other structures affecting the flatness or aesthetics of the frame beam body 1. And the frame beam body 1 includes the first outer plate 141 formed with the first bending part 151 and the second outer plate 142 formed with the second bending part 152, so that the frame beam body 1 can be disassembled, and the connection of the first outer plate 141 and the reinforcing structure 4 and the connection of the first outer plate 141 and the second outer plate 142 can be carried out separately in the state that the first outer plate 141 and the second outer plate 142 are separated, thereby reducing the probability of interference between the frame beam body 1 and the reinforcing structure 4 during assembly, and the reinforcing structure 4 can occupy most of the area of the cavity 3, and the space utilization of the cavity 3 can be improved. In addition, since part of the first outer plate 141 overlaps part of the second outer plate 142, the bonding connection of the first outer plate 141 and the second outer plate 142 can be facilitated, and the strength and rigidity of the vehicle body frame 10 can be improved, thereby improving the strength and rigidity of the entire vehicle body.

[0120] In some embodiments, as shown in Figures 7 to 9 The reinforcing structure 4 is bonded to at least one of the frame beam body 1 and the inner plate 2.

[0121] Optionally, the reinforcing structure 4 can be bonded only to the frame beam body 1, for example, the part of the reinforcing structure 4 facing the outside of the vehicle body is bonded to the part of the recessed groove 13 facing the inside of the vehicle body; the reinforcing structure 4 can also be bonded only to the inner plate 2; of course, it can also be bonded to both the frame beam body 1 and the inner plate 2. In a specific embodiment, as shown in Figures 7 to 9 The second outer plate 142 is bonded to partially overlap the first outer plate 141, the reinforcing structure 4 is bonded to the first outer plate 141 at the position where the first outer plate 141 and the second outer plate 142 overlap, and the inner plate 2 is bonded to the reinforcing structure 4 and the first outer plate 141 and the second outer plate 142, thereby forming an assembly with a closed cross section.

[0122] Thus, the relative position of the reinforcing structure 4 and the frame beam body 1 and / or the inner plate 2 can be fixed and integrated by connection, which is beneficial to strengthening the strength and rigidity of the frame beam body 1 and the inner plate 2, thereby improving the strength and rigidity of the vehicle body frame 10.

[0123] In some embodiments, as shown in Figure 5 and Figure 6As shown, the first outer panel 141 includes a first panel segment 1411 forming the first bent portion 151 and a second panel segment 1412, and the second outer panel 142 includes a third panel segment 1421 forming the second bent portion 152 and a fourth panel segment 1422, and the first outer panel 141 and the second outer panel 142 are connected in such a way that the first panel segment 1411 is closer to the inner side of the vehicle body than the third panel segment 1421 and the second panel segment 1412 is closer to the front side of the vehicle body than the fourth panel segment 1422.

[0124] In some embodiments, as shown in Figure 5 and Figure 6 the first panel segment 1411 and the third panel segment 1421 are connected by bonding, and the reinforcing structure 4 is bonded to the side of the first panel segment 1411 facing away from the third panel segment 1421, the second panel segment 1412 is closer to the front side of the vehicle body than the reinforcing structure 4, and the fourth panel segment 1422 is closer to the rear side of the vehicle body than the reinforcing structure 4.

[0125] The reinforcing structure 4 can be bonded to the first panel segment 1411 in a state in which the first outer panel 141 and the second outer panel 142 are separated. In this way, the reinforcing structure 4 can be positioned as close as possible to the second panel segment 1412. In the case where the third panel segment 1421 of the second outer panel 142 is bonded to the first panel segment 1411, the fourth panel segment 1422 can be positioned as close as possible to the reinforcing structure 4, and thus the first panel segment 1411, the second panel segment 1412, the third panel segment 1421, the fourth panel segment 1422, and the reinforcing structure 4 can be assembled compactly.

[0126] Thus, the recessed groove 13 surrounding the reinforcing structure 4 from the front side of the vehicle body, the outer side of the vehicle body, and the rear side of the vehicle body is formed by the first outer panel 141 and the second outer panel 142, and the structure is simple and easy to assemble, facilitating bonding and assembly with the reinforcing structure 4.

[0127] Furthermore, a structure in which the recessed groove 13 and the reinforcing structure 4 are bonded together can be easily formed, and the reinforcing structure 4 can be positioned close to both the first outer panel 141 and the second outer panel 142, and thus the space around the reinforcing structure in the recessed groove 13 can be reduced in a simple structure and an easy assembly manner, the outer profile of the vehicle can be reduced, and the influence on the driver's field of view can be reduced.

[0128] As for the lengths of the first panel segment 1411, the second panel segment 1412, the third panel segment 1421, and the fourth panel segment 1422, as long as the recessed groove 13 can be formed and the reinforcing structure 4 can be positioned partially or entirely in the recessed groove 13.

[0129] In some embodiments, the first panel segment 1411 and the third panel segment 1421 can partially overlap, or can almost entirely overlap. In a specific embodiment, as shown in Figure 5As shown, the third plate segment 1421 is formed slightly longer than the first plate segment 1411, and the third plate segment 1421 covers the first plate segment 1411 entirely. Thus, the first plate segment 1411 and the third plate segment 1421 have a large overlapping area, so not only is the adhesion firm, but the strength and rigidity of the laminated structure formed by the adhesion of the first plate segment 1411 and the third plate segment 1421 is improved, and the bending resistance is improved.

[0130] In some embodiments, as shown in Figure 5 and Figure 6 As shown, the side of the first plate segment 1411 facing away from the third plate segment 1421 has protrusions 1414. These protrusions 1414 can be adhesively connected to the reinforcing structure 4. The shape of these protrusions 1414 can be strip-shaped, generally consistent with the direction in which the first plate segment 1411 extends along the front-rear direction of the vehicle body, or can be scattered point-shaped. The number of these protrusions 1414 can be multiple. These protrusions 1414 help improve the strength and rigidity of the first plate segment 1411 and the third plate segment 1421, and improve the bending resistance. In addition, the first plate segment 1411 and the third plate segment 1421 are generally located on the outer side in the vehicle body width direction, and the improvement in bending resistance helps reduce the possibility of the structure formed by the frame beam body 1, the inner plate 2, and the reinforcing structure 4 partially intruding into the vehicle body interior, and helps improve the protection effect on the occupant located in the occupant compartment 20.

[0131] In some embodiments, the frame beam body 1 and the inner plate 2 are adhesively connected.

[0132] In one specific embodiment, as shown in Figures 5 to 9 The first outer plate 141 further includes a fifth plate segment 1413, and the first plate segment 1411, the second plate segment 1412, and the fifth plate segment 1413 are connected in sequence. The second outer plate 142 further includes a sixth plate segment 1423, and the third plate segment 1421, the fourth plate segment 1422, and the sixth plate segment 1423 are connected in sequence. The inner plate 2 is connected to the fifth plate segment 1413 and the sixth plate segment 1423, and the connection mode can be adhesion, for example, quick-curing glue can be used for adhesion, which is easy to operate and short in operation time.

[0133] In the adhesively connected state, the fifth plate segment 1413 and the sixth plate segment 1423 each have an overlapping portion with the inner plate 2.

[0134] Thus, the frame beam body 1 and the inner plate 2 can form a closed cavity 3, improving the strength of the vehicle, and the adhesion connection mode is easy to operate.

[0135] The inner plate 2 can be formed in a shape having concavities and convexities.

[0136] In some embodiments, as shown in Figures 7 to 9As shown, the inner plate 2 has a protruding strip portion 21 protruding toward the outside of the vehicle body, and the tube wall of the tubular reinforcing structure 42 on the inside of the vehicle body is bonded to the protruding strip portion 21.

[0137] The shape of the protruding strip portion 21 is not limited in the present application. For example, the protruding strip portion 21 can be a strip with a flat surface, or a strip with a surface having a slight curvature or curvature.

[0138] Since the inner plate 2 has the protruding strip portion 21 protruding toward the outside of the vehicle body, the inner plate 2 is more conducive to bonding to the tube wall, and the relative position of the inner plate 2 and the reinforcing structure 4 can be fixed, thereby strengthening the strength of the vehicle body frame 10. Moreover, since the inner plate 2 has the protruding strip portion 21 protruding toward the outside of the vehicle body, the deformation resistance of the inner plate 2 can be improved, thereby further strengthening the strength of the vehicle body frame 10.

[0139] Further, the inner plate 2 can also have a structure protruding toward the side away from the inner cavity 3. As shown, Figures 7 to 9 The part of the inner plate 2 bonded to the sixth plate segment 1423 can be referred to as a first bonding portion, and the part of the inner plate 2 bonded to the fifth plate segment 1413 can be referred to as a second bonding portion. The inner plate 2 has a protruding strip portion 21 protruding toward the outside of the vehicle body (toward the inner cavity 3), and a raised portion 22 is formed between the protruding strip portion 21 and the first bonding portion and / or the second bonding portion. The raised portion 22 can be raised toward the inside of the vehicle body (away from the inner cavity 3). Such a structure is conducive to further improving the bending resistance.

[0140] Next, the material of the frame beam body 1 will be described in detail.

[0141] The frame beam body 1 includes a plurality of layers of continuous fiber composite material, each layer of continuous fiber composite material including continuous fibers and a thermoplastic resin matrix, the thermoplastic resin matrix connecting the continuous fibers.

[0142] In the above technical solution, the continuous fiber 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 beam body 1. By providing a plurality of layers of continuous fiber composite material, the laying angle of the continuous fibers can be adjusted in different layers of continuous fiber composite material to improve the overall performance of the continuous fiber composite material.

[0143] In some embodiments, the plurality of layers of continuous fiber composite material are combined to form a continuous fiber composite plate, and the frame beam body 1 is formed by molding the continuous fiber composite plate.

[0144] In the above technical solution, the multi-layer continuous fiber composite material is first formed into a continuous fiber composite plate through compounding, and the continuous fiber composite plate is then formed into the frame beam body 1 with the recessed groove 13 through molding. The use of the molding process can more accurately ensure the shape and dimensional accuracy of the frame beam body, so as to ensure the mechanical properties and structural integrity of the frame beam body as much as possible.

[0145] In some embodiments, the continuous fibers include one or more combinations of organic fibers and inorganic fibers.

[0146] In the above technical solution, the organic fibers have high strength, good elasticity and flexibility. The inorganic fibers have high strength and modulus. The use of one or more combinations of organic fibers and inorganic fibers in combination with the thermoplastic resin helps to improve the strength of the single-layer continuous fiber composite material layer.

[0147] In some embodiments, the inorganic fibers include any one or any combination of glass fibers, aramid fibers or boron fibers; and / or, the organic fibers include any one or any combination of aromatic polyamide fibers and ultra-high molecular weight polyethylene fibers.

[0148] In the above technical solution, specific types of inorganic fibers and organic fibers suitable for manufacturing the frame beam body 1 are listed.

[0149] In some embodiments, the thermoplastic resin matrix includes a polypropylene (PP) resin matrix, or any one or more combinations of PA610, PA11, PA12, PA1212, PA1012 and PA1313.

[0150] In some embodiments, in the glass fiber reinforced composite material, the weight fraction of the glass fibers is greater than or equal to 60 and less than or equal to 80, the weight fraction 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 fraction of the glass fibers and the weight fraction of the thermoplastic resin matrix is 100.

[0151] In the glass fiber reinforced composite material, in addition to the thermoplastic resin matrix and the glass fibers, it can also include an auxiliary agent.

[0152] The auxiliary agent is an additive for improving and optimizing the performance of the composite material, and the auxiliary agent can include any one or a mixture of any multiple of a compatibilizer, an antioxidant, and a flame retardant. The compatibilizer is used to improve the interfacial adhesion between the resin matrix and the long glass fiber, improve the mechanical properties of the composite material, and can be, for example, a maleic anhydride grafted compatibilizer. The antioxidant can prevent or delay the oxidation and degradation of the material, reduce the possibility of degradation of the composite material due to high temperature oxidation during processing, prolong the service life of the composite material, and can be, for example, a hindered amine antioxidant or a phosphite antioxidant. The flame retardant is used to improve the flame retardant performance of the composite material, and can be, for example, a halogen-based flame retardant.

[0153] By controlling the weight fraction of the auxiliary agent in the glass fiber reinforced composite material within the above range, the processing performance of the continuous fiber and the thermoplastic resin matrix can be improved by adding the auxiliary agent, which helps to improve the final performance of the composite material.

[0154] In some embodiments, the auxiliary agent includes greater than or equal to 1 and less than or equal to 5 parts by weight of a compatibilizer and greater than or equal to 0.2 and less than or equal to 0.6 parts by weight of an antioxidant. For example, the weight fraction of the compatibilizer in the auxiliary agent is 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, or a value between any two values, and the weight fraction of the antioxidant in the auxiliary agent is 0.2, 0.3, 0.4, 0.5, 0.6, or a value between any two values.

[0155] In some embodiments, the compatibilizer includes any one or a combination of two or more of POE-g-MAH, SBS-g-MAH, SEBS-g-MAH, EPDM-g-MAH, ABS-g-MAH, ASA-g-MAH, LDPE-g-MAH, LLDPE-g-MAH, UHMWPE-g-MAH, SAN-g-MAH, and PP-GMA.

[0156] The antioxidant includes one or a combination of two or more of antioxidant 1098 and antioxidant PEP-36.

[0157] In the above technical solution, antioxidant 1098, also known as N,N'-hexamethylene bis(3,5-di-tert-butyl-4-hydroxyphenylpropionamide), is a phenolic antioxidant, and antioxidant PEP-36, also known as tris[2.4-di-tert-butylphenyl] phosphite, can be used in combination with a phenolic antioxidant.

[0158] By selecting the maleic anhydride grafted compatibilizer and the acrylic compatibilizer, the interfacial bonding performance between the continuous fibers and the thermoplastic resin matrix can be improved, and the mechanical properties of the composite material can be improved. The antioxidant can reduce the possibility of degradation of the composite material due to high temperature oxidation during processing, and prolong the service life of the composite material. By adding the compatibilizer and the antioxidant in the continuous fibers and the thermoplastic resin matrix, the mechanical properties and the service life of the vehicle body frame 10 can be improved.

[0159] In some embodiments, the water absorption of each layer of the continuous fiber composite material layer is not higher than 0.3%.

[0160] In the above technical solution, by controlling the water absorption of the single layer of the continuous fiber composite material layer in the range, the water absorption of the frame beam body 1 is in a lower range, so as to reduce the deformation of the parts caused by excessive water absorption of the frame beam body 1.

[0161] In some embodiments, in the multi-layer continuous fiber composite material layer, the performance of at least one layer of the continuous fiber composite material layer meets the following three conditions:

[0162] The elastic modulus is not less than 20Gpa, the tensile strength is not less than 900MPa, and the elongation at break is not less than 3%. By limiting the performance of the single layer of the continuous fiber composite material layer, the continuous fiber composite material formed by the multi-layer continuous fiber composite material layer can at least meet the performance requirements of the frame beam body 1 of the vehicle.

[0163] The number of layers of the continuous fiber composite material layer and the number of layers of the continuous fiber composite material layer meeting the performance requirements of the elastic modulus not less than 20Gpa, the tensile strength not less than 900MPa, and the elongation at break not less than 3% can be designed according to the specific position of the frame beam body 1 in the vehicle. It can be that all the multi-layer continuous fiber composite material layers of the fiber composite plate meet, or one or several layers meet.

[0164] In some embodiments, in the multi-layer continuous fiber composite material layer, the performance of at least one layer of the continuous fiber composite material layer satisfies the following three conditions: the elastic modulus is 20 GPa to 50 GPa, the tensile strength is 900 MPa to 1300 MPa, and the elongation at break is not less than 3%. That is, 20 GPa≤elastic modulus of the continuous fiber composite material layer≤50 GPa, 900 MPa≤tensile strength of the continuous fiber composite material layer≤1300 MPa, and 3%≤elongation at break of the continuous fiber composite material layer≤6%. Thus, the range of the elastic modulus, the tensile strength and the elongation at break of the continuous fiber composite material layer is further limited. In some embodiments, the elastic modulus of each layer of the continuous fiber composite material layer is not less than 34 GPa, the tensile strength of each layer of the continuous fiber composite material layer is not less than 918 MPa, and the elongation at break of each layer of the continuous composite material layer is not less than 3%. In this way, the performance of the continuous fiber composite material layer is further improved, so that the frame beam body 1 made of the continuous fiber composite material can be applied to positions with higher vehicle crash performance requirements.

[0165] In some embodiments, the elastic modulus of each layer of the continuous fiber composite material layer is 34 GPa to 40 GPa, the tensile strength of each layer of the continuous fiber composite material layer is 918 MPa to 1300 MPa, and the elongation at break of each layer of the continuous composite material is 3% to 6%.

[0166] That is, 34 GPa≤elastic modulus of the continuous fiber composite material layer≤40 GPa, 918 MPa≤tensile strength of the continuous fiber composite material layer≤1300 MPa, and 3%≤elongation at break of the continuous fiber composite material layer≤6%. Thus, the range of the elastic modulus and the tensile strength of the continuous fiber composite material layer is further limited.

[0167] In some embodiments, the continuous fibers of each layer of the continuous fiber composite material layer are laid in one direction, and the laying angles of the continuous fibers of adjacent two layers of the continuous fiber composite material layer are different.

[0168] In the above technical solution, the laying angle of the continuous fibers has a significant influence on the performance of the composite material, and the laying direction of the continuous fibers affects the stress distribution inside the composite material. The laying angles of the continuous fibers of adjacent two layers of the continuous fiber composite material layer are different, which helps to optimize the performance of the composite material in different directions.

[0169] In some embodiments, in the outermost two layers of the continuous fiber composite material layer on any side of the frame beam body 1 in the thickness direction, the laying angle of the continuous fibers of at least one layer is neither 0° nor 90°.

[0170] In the technical solution, the non-0° and non-90° layers can provide strength in multiple directions, and at least one of the two outermost layers can effectively absorb and disperse energy, reducing damage to the internal structure caused by external impact. Such arrangement helps to enhance the impact resistance of the frame beam body.

[0171] In some embodiments, the laying angle of the continuous fibers of the non-0° and non-90° continuous fiber composite layers is 25°-75°.

[0172] In the technical solution, the laying angle of the continuous fibers in the composite material ranges from 25° to 75°, which helps to enhance the multidirectional strength, shear strength, and fatigue resistance of the composite material.

[0173] In some embodiments, the sum of the number of layers of the non-0° and non-90° continuous fiber composite layers is 20%-40% of the total number of continuous fiber composite layers.

[0174] In the technical solution, the non-0° and non-90° layers are in a reasonable proportion, which helps to ensure that the multidirectional strength, shear strength, and fatigue resistance of the composite material are within a reasonable range, and thus the structural strength and stiffness of the frame beam body are ensured.

[0175] In some embodiments, the material of the frame beam body 1 includes glass fiber reinforced composite material, and / or the material of the inner plate 2 includes glass fiber reinforced composite material.

[0176] In some embodiments, the materials of the frame beam body 1 and the inner plate 2 can be the same or different. Specifically, the frame beam body 1 can use glass fiber reinforced composite material, the inner plate 2 can use glass fiber reinforced composite material, or both the frame beam body 1 and the inner plate 2 can use glass fiber reinforced composite material. In addition, the content of glass fibers in the glass fiber reinforced composite material used by the frame beam body 1 and the inner plate 2 can be the same or different.

[0177] Glass fiber reinforced composite material has the advantages of lightweight, high strength, good corrosion resistance, design flexibility, and processing convenience. Therefore, the frame beam body can further improve the lightweight degree of the vehicle, improve the appearance of the vehicle body, and also help to improve the production efficiency while meeting the strength and stiffness requirements of the vehicle.

[0178] In some embodiments, as shown in FIG. 1, the material of the frame beam body 1 includes glass fiber reinforced polypropylene composite material, and / or the material of the inner plate 2 includes glass fiber reinforced polypropylene composite material. Figures 4 to 6

[0179] ​Optionally, only the frame beam body 1 can adopt the glass fiber reinforced polypropylene composite material, only the inner plate 2 can adopt the glass fiber reinforced polypropylene composite material, or both the frame beam body 1 and the inner plate 2 can adopt the glass fiber reinforced polypropylene composite material, wherein the content of the glass fiber in the glass fiber reinforced polypropylene composite material adopted by the frame beam body 1 and the inner plate 2 can be the same or different.

[0180] The glass fiber reinforced polypropylene composite material has high strength and rigidity, creep resistance and good dimensional stability, thereby further improving the strength and rigidity of the frame beam body 1 and / or the inner plate 2, further improving the strength and rigidity of the vehicle body frame 10, and making the vehicle body frame 10 not easy to deform even in a high temperature environment.

[0181] In some embodiments, the glass fiber reinforced polypropylene composite material includes glass fiber and a thermoplastic resin matrix (a polypropylene resin matrix), the weight fraction of the glass fiber is greater than or equal to 60 and less than or equal to 80, the weight fraction of the thermoplastic resin matrix (the polypropylene resin matrix) is greater than or equal to 20 and less than or equal to 40, and the sum of the weight fraction of the glass fiber and the weight fraction of the thermoplastic resin matrix (the polypropylene resin matrix) is 100.

[0182] Optionally, the weight fraction of the glass fiber of the glass fiber reinforced polypropylene composite material can be 60, 65, 68, 70, 72, 75, 78, 80, etc., and of course, it can also be other values within the above range.

[0183] Therefore, it is beneficial to mold the frame beam body 1 and / or the inner plate 2.

[0184] In some embodiments, the weight fraction of the glass fiber of the glass fiber reinforced polypropylene composite material is greater than or equal to 68 and less than or equal to 75, and further 70 (which can be represented as PP+GF70).

[0185] Therefore, it is more beneficial to mold the frame beam body 1 and / or the inner plate 2.

[0186] In some embodiments, the thickness of the frame beam body 1 is 1.2mm-5mm; and / or the thickness of the single-layer glass fiber reinforced composite material is 0.2mm-0.3mm.

[0187] For example, the thickness of the frame beam body 1 is 1.2mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm or a value between any two values, and / or the thickness of the single-layer glass fiber reinforced composite material is 0.2mm, 0.22mm, 0.25mm, 0.27mm, 0.3mm or a value between any two values.

[0188] In some embodiments, the continuous fibers in the fiber-reinforced composite material are glass fibers, and the thermoplastic resin matrix is polypropylene, and the polypropylene has a melt index of not less than 30 g / 10 min and not more than 100 g / 10 min. In addition, the polypropylene has an elongation at break of not less than 50% and not more than 200%. The composite material formed by the combination of the continuous glass fibers and the polypropylene has the characteristics of high strength and high modulus of the continuous glass fibers and the good processability and recyclability of the polypropylene, which helps to improve the tensile strength and elongation at break of the single-layer continuous fiber composite layer, and the polypropylene is easy to shape.

[0201] In Table 1 and Table 2, the weight parts of the glass fiber of Example 1 and Example 2 are 65, 70, which are in the range of 60 to 80. The weight parts of the polypropylene of Example 1 and Example 2 are 35, 30, which are in the range of 20 to 40.

[0202] It can be found from Example 1 and Comparative Example 1 that when the melt index of the polypropylene is less than 30 g / 10 min, the tensile strength and the elongation at break of the produced continuous fiber composite layer cannot meet the performance requirements.

[0203] It can be found from Comparative Example 2 that when the sum of the weight parts of the polypropylene and the glass fiber is less than 100, the tensile strength and the elongation at break of the produced continuous fiber composite layer cannot meet the performance requirements.

[0204] Next, the material of the reinforcing structure 4 will be described.

[0205] In some embodiments, the material of the reinforcing structure 4 includes a glass fiber reinforced composite material.

[0206] The glass fiber reinforced composite material used in the reinforcing structure 4 can be the same as or different from the glass fiber reinforced composite material used in the frame beam body 1; it can be different in resin matrix and / or fiber content.

[0207] The glass fiber reinforced composite material has the advantages of lightweight, high strength, good corrosion resistance, design flexibility, and processing convenience, and therefore can be flexibly designed and conveniently manufactured while improving the bending resistance of the vehicle through the reinforcing structure 4.

[0208] In some embodiments, the material of the reinforcing structure 4 includes glass fiber reinforced polyamide-6.

[0209] In some embodiments, the thermoplastic resin matrix of the glass fiber reinforced composite material includes a polyamide-6 (Polyamide-6, which can be represented as PA6) resin matrix.

[0210] The glass fiber reinforced polyamide-6 material has high strength, high rigidity and other advantages, so that the strength and rigidity of the reinforcing structure 4 can be further improved, and the strength and rigidity of the vehicle body frame 10 can be further improved. Moreover, the glass fiber reinforced polyamide-6 material has good heat resistance, dimensional stability and other advantages, so it is suitable for application in the vehicle body. Moreover, the glass fiber reinforced polyamide-6 material has good processability and is suitable for processing by injection molding, extrusion molding and other methods, so it is easy to manufacture and can improve the production efficiency of the vehicle body frame 10.

[0211] In some embodiments, the glass fiber reinforced polyamide-6 includes glass fiber and a thermoplastic resin matrix (polyamide-6 resin matrix), the weight fraction of the glass fiber is greater than or equal to 60 and less than or equal to 80, the weight fraction of the thermoplastic resin matrix (polyamide-6 resin matrix) is greater than or equal to 20 and less than or equal to 40, and the sum of the weight fraction of the glass fiber and the weight fraction of the thermoplastic resin matrix is 100. Alternatively, the weight fraction of the glass fiber of the glass fiber reinforced polyamide-6 can be 60, 65, 68, 70, 72, 75, 78, 80, etc. Of course, it can also be other values within the above range.

[0212] Therefore, it is beneficial to balance the strength, rigidity and processing convenience of the reinforcing structure 4.

[0213] In some embodiments, the weight fraction of the glass fiber of the glass fiber reinforced polyamide-6 is greater than or equal to 68 or less than or equal to 75.

[0214] The glass fiber reinforced polyamide-6 with a weight fraction of 70 of the glass fiber can be represented as PA6+GF70, and the glass fiber reinforced polyamide-6 with a weight fraction of 80 of the glass fiber can be represented as PA6+GF80.

[0215] Therefore, it is beneficial to further optimize the strength, rigidity, processing convenience and processing aesthetics of the reinforcing structure.

[0216] In some embodiments, the material of the reinforcing structure 4 includes metal or alloy, and the alloy includes aluminum alloy.

[0217] When the reinforcing structure 4 is made of alloy, the reinforcing structure 4 can be extrusion molded. When the reinforcing structure 4 is made of metal, the reinforcing structure 4 can be hot gas expanded.

[0218] Therefore, the flexibility of the material selection of the reinforcing structure 4 can be improved.

[0219] Next, the structure of the reinforcing structure 4 will be described in detail.

[0220] In some embodiments, as Figures 7 to 9As shown, the reinforcing structure 4 is configured as a tubular reinforcing structure 42 having a closed cross section.

[0221] The closed cross section means that, as viewed from the cross section of the tubular reinforcing structure 42, the tube wall is in the shape of a ring with the head connected to the tail. Here, the ring shape is not limited to a circular ring shape, and can be a triangular ring shape, a quadrangular ring shape, a polygonal ring shape, an elliptical ring shape, an oblong ring shape, or the like. The tubular reinforcing structure 42 can be hollow, or can further include a structural member in the lumen.

[0222] The tubular reinforcing structure 42 having a closed cross section can effectively absorb impact energy, and has high strength and rigidity, good bending resistance, and easy processing and installation, which is conducive to improving the assembly efficiency of the vehicle body frame 10 and shortening the manufacturing cycle of the vehicle.

[0223] In some embodiments, the tubular reinforcing structure 42 is a glass fiber reinforced composite material pultruded tube, and the thickness of the tube wall of the tubular reinforcing structure 42 is 6mm to 10mm; or the tubular reinforcing structure is an aluminum alloy pultruded tube, and the thickness of the tube wall of the tubular reinforcing structure 42 is 3mm to 5mm.

[0224] As described above, the tubular reinforcing structure 42 can be made of glass fiber reinforced composite material, and can be obtained by pultrusion. The tube wall of the tubular reinforcing structure 42 can have a uniform thickness or a non-uniform thickness. In a specific embodiment, the tube wall of the tubular reinforcing structure 42 has a substantially uniform thickness.

[0225] The thickness of the tube wall of the tubular reinforcing structure 42 made of glass fiber reinforced composite material is in the range of 6mm to 10mm, for example, can be 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 10mm, and of course can be other thickness values within the range.

[0226] As described above, the tubular reinforcing structure 42 can also be made of aluminum alloy material, and can be obtained by pultrusion. The thickness of the tube wall can also be uniform or non-uniform.

[0227] The thickness of the tube wall of the tubular reinforcing structure 42 made of aluminum alloy material is in the range of 3mm to 5mm, for example, can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, and of course can be other thickness values within the range.

[0228] In this way, the strength, rigidity, weight, and outer dimensions of the reinforcing structure can be considered.

[0229] In some embodiments, as shown in FIG. 2, the tubular reinforcing structure 42 is internally provided with a reinforcing assembly 41. Figure 8 ​

[0230] The reinforcing assembly 41 is used to further enhance the strength of the tubular reinforcing structure 42.

[0231] In some embodiments, the reinforcing assembly 41 has an elastic modulus ≥ 5 GPa, a tensile strength ≥ 100 MPa, and an elongation at break ≥ 1%.

[0232] In this way, the strength of the reinforcing structure 4 can be further enhanced, thereby enhancing the strength of the vehicle body frame 10.

[0233] In some embodiments, as shown in FIG. 1, the reinforcing assembly 41 includes at least one reinforcing rib 411 (structure with two reinforcing ribs 411 is shown). Figure 8 The reinforcing rib 411 is connected to the tube wall of the tubular reinforcing structure 42 and located in the tube cavity. Figure 8

[0234] In some embodiments, the reinforcing rib 411 can be one or more. When there are multiple reinforcing ribs 411, the multiple reinforcing ribs 411 can be arranged substantially in parallel or intersecting each other in the tube cavity, and both ends of each reinforcing rib 411 can be connected to the tube wall of the tubular reinforcing structure 42.

[0235] Since the reinforcing rib 411 is connected to the tube wall of the tubular reinforcing structure 42 and located in the tube cavity, the space in the tube cavity of the tubular reinforcing structure can be effectively utilized, and the strength of the tubular reinforcing structure 42 can be enhanced without increasing the outer contour size of the tubular reinforcing structure 42, thereby enhancing the strength of the reinforcing structure 4 and further enhancing the strength of the vehicle body frame 10.

[0236] In some embodiments, the reinforcing rib 411 is formed along the entire length of the tubular reinforcing structure 42 and extends along the length direction of the tubular reinforcing structure 42.

[0237] The reinforcing rib 411 can be formed in a strip shape extending along the extension direction of the tubular reinforcing structure 42. The reinforcing rib 411 and the tubular reinforcing structure 42 can be integrally formed, for example, can be integrally formed by pultrusion.

[0238] Along the extension direction of the tubular reinforcing structure 42, the reinforcing rib 411 can have substantially the same extension length as the tubular reinforcing structure 42.

[0239] In this way, the bending resistance of the reinforcing structure can be further enhanced along the entire length of the tubular reinforcing structure 42.

[0240] In some embodiments, the reinforcing assembly 41 includes multiple reinforcing ribs, and at least part of the multiple reinforcing ribs 411 intersect each other when viewed along the cross section of the tubular reinforcing structure 42.

[0241] ​Therefore, the bending resistance of the reinforcing structure can be further improved, and the bending resistance in multiple directions can be improved.

[0242] In some embodiments, as shown in FIG. 4A, the reinforcing assembly 41 includes a first reinforcing rib 4111 and a second reinforcing rib 4112 which are connected to each other in a cross manner. The tube wall of the tubular reinforcing structure 42 includes a first tube wall 421, a second tube wall 422, a third tube wall 423 and a fourth tube wall 424 which are connected to each other in a head-to-tail manner, wherein the first tube wall 421 is arranged opposite to the third tube wall 423, and the second tube wall 422 is arranged opposite to the fourth tube wall 424, the first reinforcing rib 4111 is connected to the first tube wall 421 and the third tube wall 423 respectively, and the second reinforcing rib 4112 is connected to the second tube wall 422 and the fourth tube wall 424 respectively. Figure 8 In some embodiments, the first tube wall 421, the second tube wall 422, the third tube wall 423 and the fourth tube wall 424 can be generally flat plates, and can also be circular arc plates, wherein the shapes of the first tube wall 421, the second tube wall 422, the third tube wall 423 and the fourth tube wall 424 can be the same or different. The first tube wall 421, the second tube wall 422, the third tube wall 423 and the fourth tube wall 424 can be separate structures or one-piece components.

[0243] In some embodiments, as shown in FIG. 4B, along the up-down direction of the vehicle body, one end of the first reinforcing rib 4111 is connected to one side of the first tube wall 421 inside the tube cavity, and the other end of the first reinforcing rib 4111 is connected to one side of the third tube wall 423 inside the tube cavity; along the left-right direction of the vehicle body, one end of the second reinforcing rib 4112 is connected to one side of the second tube wall 422 inside the tube cavity, and the other end of the second reinforcing rib 4112 is connected to one side of the fourth tube wall 424 inside the tube cavity. Further, the two ends of the first reinforcing rib 4111 are respectively connected to the generally middle positions of the first tube wall 421 and the third tube wall 423; the two ends of the second reinforcing rib 4112 are respectively connected to the generally middle positions of the second tube wall 422 and the fourth tube wall 424.

[0244] Figure 8 Optionally, the first reinforcing rib 4111 and the second reinforcing rib 4112 can be separate structures or one-piece components. In a specific embodiment, the first reinforcing rib 4111 and the second reinforcing rib 4112 are one-piece components, and the first reinforcing rib 4111 and the second reinforcing rib 4112 are arranged in a generally perpendicular cross manner.

[0245] Optionally, the first reinforcing rib 4111 and the second reinforcing rib 4112 can be separate structures or one-piece components. In a specific embodiment, the first reinforcing rib 4111 and the second reinforcing rib 4112 are one-piece components, and the first reinforcing rib 4111 and the second reinforcing rib 4112 are arranged in a generally perpendicular cross manner.

[0246] ​Since the reinforcing rib 411 is connected to the tube wall of the tubular reinforcing structure 42 and is located inside the tube cavity, the space inside the tube cavity of the tubular reinforcing structure 42 can be effectively utilized, and the strength of the tubular reinforcing structure 42 can be enhanced without increasing the outer contour size of the tubular reinforcing structure 42, thereby improving the strength of the reinforcing structure 4 and thus increasing the strength of the vehicle frame 10.

[0247] In some embodiments, such as Figures 7 to 9 As shown, the outer wall of the tubular reinforcing structure 42 is bonded to the frame beam body 1; the inner wall of the tubular reinforcing structure 42 is bonded to the inner panel 2.

[0248] Optionally, the outer wall of the tubular reinforcing structure 42 can be bonded to the frame beam body 1; the inner wall of the tubular reinforcing structure 42 can be bonded to the inner panel 2; or the outer wall of the tubular reinforcing structure 42 can be bonded to the frame beam body 1, and the inner wall of the tubular reinforcing structure 42 can be bonded to the inner panel 2.

[0249] In some embodiments, the two opposite outer surfaces of the tubular reinforcing structure 42 are respectively bonded to the frame beam body 1 and the inner plate 2. Figure 8 As shown in the example, roughly along the width direction of the vehicle body (left-right direction), the two outer surfaces of the tubular reinforcing structure 42, which are positioned opposite to the cavity, are bonded to the frame beam body 1 and the inner panel 2, respectively.

[0250] This allows for more efficient use of the space within the cavity 3, reduces the outer contour dimensions of the vehicle frame 10, minimizes the impact of the vehicle frame 10 on the driver's field of vision, and simplifies the bonding process compared to welding.

[0251] The vehicle body frame 10 described above will now be explained.

[0252] In some embodiments, such as Figure 1 and Figure 2 As shown, the vehicle frame 10 includes a vehicle pillar assembly 101, a crossbeam assembly 102, a side beam assembly 103, and a sill beam assembly 104; the frame beam body 1 includes a vehicle pillar, a side beam, a crossbeam, and a sill beam. The frame beam body 1, the reinforcing structure 4, and the inner panel 2 together form at least a portion of the vehicle pillar assembly 101 and / or at least a portion of the crossbeam assembly 102 and / or at least a portion of the side beam assembly 103 and / or at least a portion of the sill beam assembly 104.

[0253] In some embodiments, along the front-rear direction of the vehicle body, the vehicle body pillar assembly 101 can include at least one of a front pillar assembly (also referred to as an "A-pillar assembly") 1011, a middle pillar assembly (also referred to as a "B-pillar assembly") 1012, and a rear pillar assembly (also referred to as a "C-pillar assembly") 1013; the vehicle body pillar includes at least one of a front pillar, a middle pillar, and a rear pillar. The structure collectively formed by the frame beam body 1, the reinforcement structure 4, and the inner panel 2 as described above can be used as part or all of the front pillar assembly (also referred to as the "A-pillar assembly") 1011, and / or part or all of the middle pillar assembly (also referred to as the "B-pillar assembly") 1012, and / or part or all of the rear pillar assembly (also referred to as the "C-pillar assembly") 1013.

[0254] This can enhance the strength and rigidity of the vehicle body pillar and the beam member, and improve the bending resistance of the vehicle body frame 10 in the event of a collision. Furthermore, the vehicle body pillar, the beam member, and the like can be reduced in size.

[0255] Furthermore, the above-described structure can be applied to any one of the front pillar, the middle pillar, and the rear pillar, and thus, on the one hand, the strength and rigidity of the entire vehicle body can be improved, and on the other hand, the vehicle body pillar can be reduced in size, the passenger compartment can be increased in size, and the entire vehicle body can be reduced in weight.

[0256] In some embodiments, the structure collectively formed by the frame beam body 1, the reinforcement structure 4, and the inner panel 2 is used as at least part of the front pillar assembly (also referred to as the "A-pillar assembly") 1011.

[0257] This can satisfy the strength and rigidity requirements of the front pillar assembly, and the front pillar assembly can have high bending resistance, satisfy the requirements of the vehicle for a 25% offset collision, and inhibit the intrusion or the degree of intrusion of the front pillar assembly into the passenger compartment 20, which is advantageous for protecting the occupant (e.g., the driver) located in the passenger compartment 20. In addition, the front pillar assembly 1011 can be reduced in size, which is advantageous for reducing the influence on the field of view of the driver.

[0258] In some embodiments, the front pillar assembly 1011 includes a front pillar assembly upper member 1011a and a front pillar assembly lower member 1011b connected to each other, the front pillar assembly upper member 1011a is connected to the side sill assembly 103 and the front pillar assembly lower member 1011b, and the frame beam body 1, the reinforcement structure 4, and the inner panel 2 collectively form the front pillar assembly upper member 1011a.

[0259] The front pillar assembly 1011 includes a front pillar assembly upper member 1011a and a front pillar assembly lower member 1011b connected to each other. Optionally, the front pillar assembly upper member 1011a and the front pillar assembly lower member 1011b are connected by a front pillar joint (not shown in the drawings). Generally, there is one front pillar assembly 1011 on each side along the vehicle body width direction, and each front pillar assembly upper member 1011a supports a front windshield. The front pillar assembly upper member 1011a can adopt any of the embodiments of the application described above.

[0260] Thus, the bending resistance of the front pillar assembly upper member of the vehicle body can be improved, and the range of the driver's field of view can be reduced, which is conducive to providing the driver with a comfortable large field of view.

[0261] In some embodiments, the vehicle 1000 includes a vehicle body frame 10, which includes the frame beam body 1, the reinforcing structure 4, and the structure formed by the inner plate 2 described above.

[0262] Thus, the strength of the vehicle body frame 10 can be improved, the degree of lightweight of the vehicle body frame 10 can be improved, and the influence of the vehicle body frame 10 on the driver's field of view can be reduced.

[0263] In some embodiments, as shown in Figure 1 the vehicle further includes a chassis 30, the vehicle body frame 10 is mounted to the chassis and together forms a passenger compartment 20, and the vehicle body frame 10 includes a vehicle body pillar assembly 101, the frame beam body 1, the reinforcing structure 4, and the inner plate 2 together form at least part of the vehicle body pillar assembly 101.

[0264] Thus, the strength of the vehicle body pillar assembly 101 can be improved, and the influence of the vehicle body pillar assembly 101 on the driver's field of view can be reduced.

[0265] In some embodiments, as shown in Figure 3 the vehicle 1000 further includes a battery device 200, and the battery device 200 is mounted to the chassis 30.

[0266] The battery device 200 can include a housing defining an accommodation space, and a plurality of battery cells, a busbar, and the like accommodated in the accommodation space of the housing. The structure of the battery device 200 can adopt the structure of an existing battery device 200 (such as a battery pack), which will not be described here.

[0267] The housing of the battery device 200 can be mounted to the chassis 30. The chassis 30 can include a floor 31, and the battery device 200 can be mounted below the floor 31, or the housing itself can constitute at least part of the floor 31.

[0268] Thus, the vehicle 1000 has excellent strength and rigidity performance, is lightweight, and does not easily affect the driver's field of view, and on the other hand, the space utilization rate of the bottom of the vehicle is improved, the space occupied by the battery device 200 in the passenger compartment and the trunk is reduced, and a more spacious seating and storage space is provided. Moreover, the battery device 200 is installed on the chassis 30, which can reduce the direct impact of the battery device 200 and the like on the passengers in the event of a vehicle collision. In addition, the battery device 200 is centrally installed on the chassis 30, which facilitates maintenance and replacement and reduces the complexity of routine maintenance.

[0269] In some embodiments, as shown in Figure 1 and Figure 7 The shell of the battery device 200 forms at least part of the floor 31 of the passenger compartment 20.

[0270] For example, the upper shell wall in the shell of the battery device 200 serves as part or the entire floor 31.

[0271] Thus, the redundancy of the vehicle can be reduced, thereby reducing the overall weight. Moreover, the packaging space of the battery module can be increased, the internal layout of the vehicle can be optimized, and the space utilization rate can be improved.

[0272] In some embodiments, as shown in Figure 1 The vehicle body frame 10 is detachably connected to the upper portion of the chassis 30.

[0273] The vehicle body frame 10 and the chassis 30 can be connected by bolts or the like.

[0274] Thus, it is beneficial to simplify the assembly process, improve the production efficiency of the vehicle, and facilitate the organization of specialized cooperation.

[0275] The manufacturing method of the vehicle provided by the embodiments of the present application can include the following steps S1-S3.

[0276] S1: providing a plurality of outer plates 14, inner plates 2, and reinforcing structures 4;

[0277] S2: bonding and connecting the plurality of outer plates 14 to form a frame beam body 1 having a recessed groove 13, the recessed groove 13 being surrounded by at least two outer plates 14 having a bent portion 15;

[0278] S3: bonding the inner plate 2 to the frame beam body 1 such that the inner plate 2 and the recessed groove 13 of the frame beam body 1 jointly form a cavity 3 and the reinforcing structure 4 is located in the cavity 3.

[0279] Since the frame beam body 1 comprises a plurality of outer plates 14 connected together, and at least two bending portions 15 are formed by different outer plates 14, when the reinforcing structure 4 is connected to the frame beam body 1, the reinforcing structure 4 can be connected to the outer plates 14 in a state that the reinforcing structure 4 is separated from the plurality of outer plates 14, the operation space is increased, the assembly difficulty of the vehicle is reduced, and the space between the reinforcing structure 4 and the outer plates 14 can be reduced, the assembly of the frame beam body 1 and the reinforcing structure 4 can be realized in a state that the size of the inner cavity is reduced, so that the influence of the vehicle on the driver's field of view can be reduced while meeting the strength and rigidity requirements of the vehicle. Moreover, since the reinforcing structure 4 is arranged in the cavity 3 and connected between the frame beam body 1 and the inner plate 2, the bending resistance of the vehicle can be improved to meet the 25% offset collision requirement of the vehicle. In addition, since the frame beam body 1 is made of fiber composite material, the lightweight degree of the frame beam body 1 and even the vehicle can be improved while meeting the strength requirement of the frame beam body 1.

[0280] In some embodiments, as shown in Figures 5 to 9 the plurality of outer plates 14 comprises a first outer plate 141 having a first bending portion 151 and a second outer plate 142 having a second bending portion 152; and the frame beam body 1 having the recessed groove 13 is formed by bonding the plurality of outer plates 14, comprising: bonding the reinforcing structure 4 to the first side of the first outer plate 141, bonding the second outer plate 142 to the second side of the first outer plate 141 opposite to the first side in the plate thickness direction, and arranging the reinforcing structure 4 in the recessed groove 13 surrounded by at least the first outer plate 141 and the second outer plate 142.

[0281] In a specific embodiment, as shown in Figure 6 the first outer plate 141, the second outer plate 142 and the reinforcing structure 4 are prepared, wherein the first outer plate 141 and the second outer plate 142 are fiber composite plates and each is formed with a bending portion 15; the first outer plate 141 and the reinforcing structure 4 can be bonded together to form an assembly, wherein the reinforcing structure 4 is arranged in the half groove formed by the bent first outer plate 141; then, the second outer plate 142 is bonded to the side of the first outer plate 141 away from the reinforcing structure 4 (i.e., the outer side in the vehicle body width direction), wherein the first outer plate 141 and the second outer plate 142 form the recessed groove 13 and the reinforcing structure 4 is arranged in the recessed groove 13; further, the inner plate 2 is bonded to the first outer plate 141 and the second outer plate 142 so that the first outer plate 141, the second outer plate 142 and the inner plate 2 surround a cavity 3, and the reinforcing structure 4 is arranged in the cavity 3, thereby forming the structure as shown in Figures 7 to 9 .

[0282] Thus, the first outer plate 141 and the second outer plate 142 can be bonded to form the frame beam body 1, and the structure is simple. Moreover, since the frame beam body 1 comprises the first outer plate 141 formed with the first bending part 151 and the second outer plate 142 formed with the second bending part 152, the frame beam body 1 can be disassembled, and a part of the frame beam body 1 can be connected with the reinforcing structure 4, and then another part of the frame beam body 1 can be connected with the reinforcing structure 4, so as to reduce the probability of interference when the frame beam body 1 is connected with the reinforcing structure 4, and the reinforcing structure 4 can occupy most of the area of the cavity 3, so as to improve the space utilization of the cavity 3. Since a part of the first outer plate 141 overlaps with a part of the second outer plate 142, the bonding connection of the first outer plate 141 and the second outer plate 142 can be facilitated, and the strength and rigidity of the frame beam body 1 can be improved, so as to improve the strength and rigidity of the vehicle body frame 10.

[0283] In some embodiments, the reinforcing structure 4 is formed by pultrusion or by extrusion or by hot gas expansion.

[0284] When the reinforcing structure 4 is of a fiber composite material, the reinforcing structure 4 can be formed by pultrusion; when the reinforcing structure 4 is of an alloy material, such as an aluminum alloy, the reinforcing structure 4 can be formed by extrusion; and when the reinforcing structure 4 is of a hot-formed steel material, the reinforcing structure 4 can be formed by hot gas expansion.

[0285] The reinforcing structure 4 is formed by pultrusion, which is conducive to obtaining good strength and rigidity, and the reinforcing structure can have a complex cross section, which is conducive to further optimizing the mechanical properties and shape flexibility of the reinforcing structure, and improving the production efficiency of the reinforcing structure 4. The reinforcing structure 4 is formed by extrusion, which is conducive to efficiently manufacturing the reinforcing structure at a lower cost. The reinforcing structure 4 is formed by hot gas expansion, which is conducive to improving the production efficiency and has wider material applicability.

[0286] In some embodiments, the reinforcing structure 4 is configured as a tubular reinforcing structure 42.

[0287] The tubular reinforcing structure 42 can effectively absorb impact energy, has high strength and rigidity, has good bending resistance, is easy to process and install, is conducive to improving the assembly efficiency of the vehicle body frame 10, and is conducive to shortening the manufacturing cycle of the vehicle.

[0288] In the following, an embodiment of the present application will be described in detail. Figures 1 to 9 An embodiment of the present application will be described in detail.

[0289] In the specific embodiment, the vehicle comprises a vehicle body frame 10, which comprises a frame beam body 1, and the structure of the specific embodiment mainly relates to a vehicle body front pillar assembly 1011 in the vehicle body frame 10. The frame beam body 1 is a fiber-reinforced composite material. The frame beam body 1 (at least the part forming the vehicle body front pillar) is disassembled into a first outer plate 141 and a second outer plate 142, the first outer plate 141 and a pultruded tube as a reinforcing structure 42 are glued, and then the glued combination and the second outer plate 142 are further glued, and then the inner plate 2 is bonded to form a closed limited cavity 3. Such a structure objectively solves the interference problem in the assembly process of the reinforcing structure 4 and the frame beam body 1, the reinforcing structure 4 can make full use of the space structure of the vehicle body front pillar assembly 1011, greatly improves the bending resistance of the vehicle body front pillar assembly 1011, and significantly improves the small offset collision effect. Moreover, the visual angle of the vehicle body front pillar assembly 1011 is also reduced, and the driver's visual space is improved.

[0290] The tubular reinforcing structure can adopt a composite material pultruded tube (for example Figure 4 shown), can also adopt an aluminum alloy extruded beam (for example Figure 5 shown), and can also adopt a hot gas expansion tube beam (for example Figure 6 shown).
