The features of the examples and embodiments described below may be combined with each other without conflict.
Referring to fig. 1 and 2, an embodiment of the present application provides a profile type integrated frame 100, which is applicable to frames of automobiles, frames of ships, and the like. For example, the vehicle can be applied to commercial vehicles such as new energy vehicles or fuel vehicles, and the commercial vehicles can comprise vehicles such as cargo vehicles, trucks, semi-trailer trucks, flat trailers, trucks, heavy trucks, light trucks and the like. The frame 100 may include: frame rail 10 and bottom plate 20, frame rail 10 and bottom plate 20 are the integrative extrusion molding structure of section bar formula. Frame rail 10 is attached to the lower surface of floor 20, and frame rail 10 and floor 20 enclose a hollow cavity 30 for receiving a vehicle component. The front section of the frame 100 is also provided with a cab support beam 50, which is connected to the front end of the frame rail 10 in the longitudinal direction, and the cab support beam 50 protrudes from the floor 20. It will be appreciated that the longitudinal direction is the longitudinal direction of the vehicle, and that the longitudinal direction X of the frame rail 10, the floor 20 and the hollow cavity 30 all coincides with the longitudinal direction of the vehicle.
According to the profile type integrated frame 100, the frame longitudinal beam 10 and the bottom plate 20 are processed and molded into the highly integrated structure, and a cross beam is not required to be arranged in the middle of the frame structure, so that the weight of the frame is effectively reduced, and the design requirement of the light weight trend is met. The frame has no cross beam and bolt assembly, can be directly used, and is more rapid and efficient to install. The bottom plate 20 can be directly used as a bottom plate of a cargo box and can be assembled with a side plate of the cargo box, so that the problems of difficult and complex assembly of the frame and the cargo box are solved. Cab support beams 50 are provided protruding from floor 20 and may be used to mount the cab of a vehicle. The hollow cavity 30 formed by enclosing the frame longitudinal beam 10 and the bottom plate 20 can be used for accommodating components such as a power battery of a new energy vehicle, and the space of the frame structure is effectively utilized. The vehicle-mounted component may be a large-capacity power battery, a large-capacity liquid fuel tank, a gas storage tank, an oil tank, a storage battery, an engine, a gearbox, an arrangement box of an electric control device, an arrangement box of other functional devices, and the like, which is not limited in the application.
In some alternative embodiments, the frame 100 may further include packaging plates covering both ends of the hollow cavity 30 for sealing the hollow cavity 30. Thus, after the components such as the power battery are placed in the hollow cavity 30 and sealed by the packaging plate, concealment and sealing performance can be improved. Optionally, the package plate is an aluminum plate, and is welded to the integrally formed structure formed by the frame rail 10 and the bottom plate 20.
In some alternative embodiments, the frame rail 10 and the bottom plate 20 are made of aluminum alloy, and the frame rail 10 and the bottom plate 20 are integrally formed by extrusion, that is, the aluminum alloy is strongly extruded through an extrusion process to form the frame rail 10 and the bottom plate 20 into an integrally formed structure, and the cross sections of the integrally formed structure along a plane perpendicular to the length direction X of the hollow cavity 30 are all the same in the first direction Y.
Thus, the frame longitudinal beam 10 and the bottom plate 20 are molded into an integrated structure by adopting an aluminum alloy extrusion molding process, the cavity space of a hollow cavity formed by an aluminum alloy wall integrated by extrusion and a splice welding aluminum plate is large, the hollow cavity can be used as an installation shell of a battery core or fuel such as methanol, the box body of a power battery is not required to be connected to a frame through a support, and the problem of space waste caused by battery installation and fuel tank body installation is effectively solved. The inner wall of the hollow cavity can be used as the shell of the liquid fuel tank (or the power battery box) of the vehicle, so that the container bottom plate, the container bottom plate and the shell of the battery are integrated. Because of the large amount of use of the aluminum alloy material, the aluminum alloy material has the advantages of recycling and recycling, and the aluminum alloy material is applied, highly integrated and the frame is highly integrated, so that the weight of the frame is effectively reduced. Meanwhile, the arrangement requirements of a large-electric-quantity power battery and a large-volume liquid fuel tank can be met, the installation of the power battery and a container is reduced, the problem of complex assembly of the whole vehicle is solved, the arrangement space is optimized, the production and assembly process of parts such as a frame and a container is simplified, and the cost is reduced. The requirements of light development of the commercial vehicle frame, reduction of market competition cost, improvement of production efficiency, carbon neutralization and the like are met.
In some alternative embodiments, the cross-section of cab support beam 50 in the plane of first direction Y coincides with the cross-section of frame rail 10 in the plane of first direction Y, which is perpendicular to the length direction X of hollow cavity 30. In this manner, cab support beam 50 is facilitated to be formed with frame rail 10. The cab support beam 50 and the frame rail 10 have the same cross section, and a hollow sub-cavity 51 that communicates with the hollow cavity 30 and corresponds to a region of the front section of the vehicle can be formed, so that the space of the frame can be fully utilized for placing vehicle-mounted components.
It can be appreciated that the cross section of the integrated frame formed by extrusion of aluminum alloy is mainly divided into two main parts: namely a beam portion at the lower end and a floor portion at the upper end. The main body extrusion section can be integrally extruded and formed according to the requirements of different equipment sizes, or can be separately extruded and formed in a plurality of parts, and then the main body extrusion section is assembled into a whole through connection modes such as clamping, bonding, riveting and the like.
In some alternative embodiments, cab support beam 50 is an extruded profile integral structure with frame rail 10, and cab support beam 50 is formed by partially removing cargo floor 20 and frame rail 10 from the front section of the frame. That is, the body extruded section of the frame may be formed as an integral extrusion, and then the cargo floor 20 and the frame rail 10 of the front section of the frame may be partially removed by cutting or the like to form the cab support beam 50. Further, the frame rail 10, the cab supporting beam 50 and the bottom plate 20 can be made of aluminum alloy, and the frame rail 10, the cab supporting beam 50 and the bottom plate 20 are integrally formed by extrusion, so that the processing is convenient. In actual operation, the frame longitudinal beam and the bottom plate can be extruded into an integral structure, and then the area, corresponding to the cab of the vehicle, on the bottom plate is cut and removed, and a space for installing the cab is reserved. The portion of the front end of the frame rail that is exposed from the cut-out region of the floor and protrudes beyond the floor may be referred to as a cab support beam.
In other alternative embodiments, cab support beam 50 is an extruded, one-piece structure and is connected to frame rail 10 by a connector. That is, frame rail 10 and floor 20 are integrally extruded, cab support beam 50 is separately integrally extruded, and cab support beam 50 is assembled integrally with frame rail 10. That is, in other examples, the frame rail and the bottom plate are integrally formed by extrusion of the same material, and the cab support beam is integrally formed by extrusion alone, and the cab support beam and the frame rail are integrally connected and assembled by physical connection.
In some alternative embodiments, frame rail 10 includes a bottom rail 11 and two side rails 12, with the two side rails 12 being located on opposite sides of bottom rail 11 in a first direction Y that is perpendicular to the length direction X of hollow cavity 30. The bottom side beam 11 is located below the bottom plate 20, and one end of the side beam 12 is connected to the bottom side beam 11, and the other end is connected to the bottom plate 20. In this way, the rocker 11, the two side rails 12, and the bottom plate 20 enclose the hollow cavity 30. It can be appreciated that the bottom side beam 11, the two side beams 12 and the bottom plate 20 are all made of aluminum alloy, and are formed into an integrally formed structure by an extrusion process. Alternatively, the cross section of the hollow cavity 30 along the plane of the first direction Y is quadrangular, and the cross section is perpendicular to the length direction X of the hollow cavity 30. It can be understood that the quadrilateral structure atress is better, and structural strength is higher, can improve the bulk strength of frame. Alternatively, the thickness of side rail 12 is greater than the thickness of bottom rail 11 to increase the load bearing capacity of both sides of frame rail 10.
Referring to fig. 3, in some alternative embodiments, the cross section of the plane of the hollow cavity 30 along the first direction Y may be trapezoidal, two side beams 12 are symmetrically disposed on two sides of the bottom beam 11 along the first direction Y, and the length of the upper bottom edge of the cross section is greater than the length of the lower bottom edge of the cross section, so that the cross section of the hollow cavity 30 is in an inverted trapezoid shape. It can be understood that the stress on two sides of the inverted trapezoid structure is uniform, the bearing capacity of the upper surface is strong, and the structural strength is higher, so that the overall strength of the frame is improved.
Further, the two side beams 12 are arc-shaped in cross section along the plane of the first direction Y and are recessed toward the inside of the hollow cavity 30. It can be understood that the atress of the structural mode both sides of arc side is more even, and structural strength is higher, can improve the bulk strength of frame equally to the structure of arc side is more convenient for extrusion processing shaping.
In some alternative embodiments, the two longitudinal sides of the upper surface of the bottom plate are further provided with fixing base plates 21, and the bottom plate 20 and the two fixing base plates 21 are integrally formed structures formed by profile extrusion for mounting and fixing the cargo box. Alternatively, two fixing substrates 21 are connected to both sides of the upper surface of the base plate 20 along a first direction Y, which is perpendicular to the length direction X of the hollow cavity 30. It will be appreciated that the frame rail 10, the bottom plate 20 and the two fixing base plates 21 are all made of aluminum alloy, and are formed into an integrally formed structure by an extrusion process. Thus, the chassis 100 of the present application can be used as the chassis of the cargo box directly, and the chassis 20 can be directly assembled with the side panels of the cargo box through the fixing base plate 21, thereby solving the problems of difficult and complex assembly of the chassis and the cargo box. Optionally, the fixed base plate 21 is provided with a mounting portion for mounting the cargo box. For example, the mounting portion may be a screw hole, a mounting groove, or the like for mounting engagement with a side panel of the cargo box. Therefore, the container can be directly installed on the two side protruding parts on the upper surface of the bottom plate, and is assembled with the bottom plate in a bolt connection or push-in clamping manner.
In some alternative embodiments, the length of frame rail 10 and bottom plate 20 are the same along the length direction X of hollow cavity 30. Thus, the hollow cavity 30 is formed to have a longer length and a larger space, and more components can be placed in the space of the frame.
The length of frame rail 10 is less than the length of bottom plate 20 along a first direction Y perpendicular to the length direction X of hollow cavity 30. It will be appreciated that the width of frame rail 10 is less than the width of floor 20, allowing room for the mounting of wheels and also reducing the weight of the frame.
Along a first direction Y perpendicular to the length direction X of hollow cavity 30, frame rail 10 is positioned in the middle of bottom plate 20. Thus, when the components such as the power battery are placed in the hollow cavity 30 formed by enclosing the frame longitudinal beam 10 and the bottom plate 20, the weight of the power battery can be kept at the middle position of the vehicle, and the stress is more balanced and safer and more reasonable.
In some alternative embodiments, the thickness of the bottom plate 20 gradually decreases from the middle to both sides along a first direction Y perpendicular to the length direction X of the hollow cavity 30. The bottom plate 20 is curved along a bottom surface of a cross section of a plane in which the first direction Y is perpendicular to the longitudinal direction X of the hollow cavity 30, and is recessed toward the inside of the hollow cavity 30. It will be appreciated that the base plate 20 forms an equal stress beam with a thick middle and thin ends, and has a large load bearing capacity. Further, a plurality of reinforcing ribs may be provided in the middle of the floor 20 to enhance the strength and rigidity of the cargo box floor. The wall thickness of the frame longitudinal beam 10, that is, the thickness of the side rail 12, can be set to be larger, so that the bearing capacity is improved, and the reinforcing ribs can be added in the middle of the frame longitudinal beam 10 to play a role of a main bearing component and a mounting matrix, so that the structure such as a suspension bracket, a cab suspension bracket and other device brackets of a vehicle can be mounted on two sides of the frame longitudinal beam 10 more conveniently.
In some alternative embodiments, as shown in fig. 2, at least one of frame rail 10 and bottom plate 20 is a porous profile structure. It will be appreciated that at least one of frame rail 10 and bottom panel 20 may be formed by extrusion to form a corrugated board structure to strengthen and enhance the strength and rigidity of the frame. The inside corner location of at least one of frame rail 10 and bottom plate 20 may be formed into a cavity by extrusion. Therefore, the small cavity part is extruded at the inner side corner position of the frame integrally formed by aluminum alloy extrusion, and the bending resistance of the frame integrally formed by aluminum alloy extrusion can be greatly enhanced.
The inner wall of the hollow cavity 30 may be provided with a guide groove. It will be appreciated that the frame rail 10 may be slotted into the inner wall of the bottom wall of the corresponding hollow cavity 30 so that components such as a power cell may be pushed inwardly into the hollow cavity into assembly through the guide slot as a whole and then sealed by the package plate.
The profile type integrated frame can be manufactured by the following two modes:
(1) The frame rail 10 and the bottom plate 20 which are integrally formed are formed through an extrusion molding process, the frame rail 10 is positioned on the lower surface of the bottom plate 20, a hollow cavity 30 for accommodating a vehicle-mounted component is formed by surrounding the frame rail 10 and the bottom plate 20, and at least part of the inner wall of the hollow cavity 30 can be used as a shell of a liquid fuel tank (or a power battery box) of a vehicle. Then, the region of the floor panel 20 corresponding to the cab of the vehicle is cut so that the front end portion of the frame rail 10 protrudes from the floor panel 20 in the longitudinal direction X of the vehicle, and the portion of the frame rail 10 protruding from the floor panel 20 forms a cab support beam 50. Alternatively, the frame rail 10 and the bottom plate 20 are made of aluminum alloy, and the frame rail 10 and the bottom plate 20 are integrally formed by extrusion, that is, the aluminum alloy is strongly extruded by an extrusion process to be formed by a hole die, so that the frame rail 10 and the bottom plate 20 form an integrally formed structure.
(2) The frame rail 10 and the bottom plate 20 are integrally formed through an extrusion molding process, the frame rail 10 is positioned on the lower surface of the bottom plate 20, the frame rail 10 and the bottom plate 20 are enclosed to form a hollow cavity 30 for accommodating vehicle-mounted components, and at least part of the inner wall of the hollow cavity 30 can be used as a shell of a liquid fuel tank (or a power battery box) of a vehicle. The cab support beam 50 of an integral structure is formed by an extrusion molding process, and the cab support beam 50 is connected to the front end of the frame rail 10 by a connector along the longitudinal direction X of the vehicle. Alternatively, cab support beam 50 may be integrally assembled with frame rail 10 by a physical connection such as snap fit, adhesive, rivet, etc.
Thus, the profile type integrated frame with the integrated structure can be formed, and the hollow cavity can be formed by utilizing the frame space for placing the vehicle-mounted part of the vehicle. It can be appreciated that the cross section of the integrated frame formed by extrusion of aluminum alloy is mainly divided into two main parts: namely a beam portion at the lower end and a floor portion at the upper end. The main body extrusion section can be integrally extruded in the first mode according to the requirements of different equipment sizes, or can be separately extruded in the second mode in a plurality of parts, and then assembled into a whole through connection modes such as clamping, bonding, riveting and the like.
Referring to fig. 1, 4-6, an embodiment of the present application provides a vehicle 200 including a cab 43, a cargo box 41, a power plant 42, and a frame 100. In the above embodiments and implementations, the description of the frame 100 is equally applicable to the vehicle 200 of the present embodiment. It will be appreciated that the longitudinal direction X of the hollow cavity 30 coincides with the longitudinal direction of the vehicle 200. The power unit 42 is mounted in the hollow cavity 30 of the vehicle frame 100, the cargo box 41 is mounted on the floor 20, and the cab 43 is mounted on the cab support beam 50. Alternatively, power device 42 may include at least one of a power battery and a fuel tank. Further, the power battery comprises an electric core, and the inner wall of the electric core surrounded by the hollow cavity 30 of the frame 100 can be used as a housing of the power battery. It can be understood that the hollow cavity formed by enclosing the supporting beam and the bottom plate can be used as the shell of the power battery box (or the liquid fuel tank) of the vehicle, so that the container bottom plate, the frame beam and the shell of the battery are integrated, and the highly integrated frame structure with product engineering application and multifunctional structure is realized.
According to the vehicle 200, the frame 100 is formed into the highly integrated structure by processing the frame longitudinal beam 10 and the bottom plate 20, and a cross beam is not required to be arranged in the middle of the frame structure, so that the weight of the frame is effectively reduced, and the design requirement of the light weight trend is met. The frame has no cross beam and bolt assembly, can be directly used, and is more rapid and efficient to install. The bottom plate 20 can be directly used as a bottom plate of a cargo box and can be assembled with a side plate of the cargo box, so that the problems of difficult and complex assembly of the frame and the cargo box are solved. The hollow cavity 30 formed by enclosing the frame longitudinal beam 10 and the bottom plate 20 can be used for accommodating components such as a power battery and the like, and the space of the frame structure is effectively utilized.
In some alternative embodiments, the vehicle 200 may further include wheels 45, front and rear axles 46, leaf spring suspensions 47, electronic control device arrangement boxes 48, other device arrangement boxes 49, and the like. The front and rear axles 46 are connected to the frame rail 10 of the frame 100 via leaf spring suspensions 47, and the wheels 45 are connected to the front and rear axles 46. The mounting bolts for carrying the larger devices such as the leaf spring suspension 47 may be connected by a bushing-embedded structure or the like. The common connecting bolts may be connected by grooving the inner wall of the frame rail 10, welding nuts on the inner side of the outer wall, or by inserting a nut plate on the inner side of the frame rail 10 for screwing.
Alternatively, the cab support beam 50 may be formed with a hollow sub-cavity 51 corresponding to an area of the front section of the vehicle and communicating with the hollow cavity 30, and the electric control device arrangement box 48 may be installed in the hollow sub-cavity 51 corresponding to an area of the front section of the vehicle (i.e., corresponding to the cab 43). The power unit 42 may be installed in an area of the hollow cavity 30 corresponding to the middle section of the vehicle, and the other unit arrangement case 49 may be installed in an area of the hollow cavity 30 corresponding to the rear section of the vehicle, reasonably utilizing the space of the vehicle frame.
