Referring to fig. 1 to 5, a frame assembly according to an embodiment of the present invention is shown, which includes two side-by-side longitudinal beams 10 and a plurality of cross beams disposed between the longitudinal beams 10, and the frame assembly further includes a reinforcing component 40 disposed on one end of the longitudinal beams 10 near a front cabin of an automobile, wherein:
the longitudinal beam 10 comprises a longitudinal beam body 11 and an upper side wall 12 and a lower side wall 13 which extend outwards from two sides of the longitudinal beam body 11, the reinforcing assembly 40 comprises a reinforcing part 41 and a plurality of supporting parts 42 which extend outwards from the reinforcing part 41, and the reinforcing assembly 40 is connected with the two longitudinal beams 10 through the plurality of supporting parts 41 respectively so as to form a reinforcing structure on two opposite sides of the two longitudinal beams 10 respectively.
It can be understood that the frame assembly main body structure is formed by a plurality of cross beams on the side rails 10 arranged side by side, wherein the side rails 10 comprise a side rail main body 11 and an upper side wall 12 and a lower side wall 13 which extend outwards from two sides of the side rail main body 11; the reinforcing component 40 is arranged at one end, close to a front cabin of an automobile, of the longitudinal beam 10, the reinforcing component 40 is connected with the lower side wall 13 of the longitudinal beam 10 through a plurality of supporting portions 42 extending outwards through reinforcing portions 41, the supporting portions 42 are connected with the longitudinal beam 10 to form a reinforcing structure, specifically, the number of the supporting portions 42 is four, the reinforcing component 40 is in an X-shaped structure, a triangular reinforcing structure is formed between the supporting portions 42 and the longitudinal beam 10, compared with the design that a plurality of transverse beams are additionally arranged in the prior art, the reinforcing component 40 is designed into the X-shaped structure, the triangular reinforcing structure is formed between the reinforcing component 40 and the longitudinal beam 10, the stability between the reinforcing component 40 and the longitudinal beam 10 is enhanced, the strength of the middle section of the reinforcing component 40 is enhanced, the anti-torsion bending deformation capacity of the two ends of the reinforcing component 40 is enhanced, the bending strength of the whole frame is further improved, and therefore the reinforcing component 40 is designed into the X-shaped structure to replace the original transverse beam to enhance the bending rigidity of the whole frame, and the whole bending of the whole frame can ensure that the whole frame is unchanged in weight. Therefore, the technical scheme of the invention solves the problem that the frame with high bending rigidity and light weight is lacked in the prior art.
Furthermore, the reinforcing part 41 is respectively extended with two supporting parts 42 towards two sides of the two longitudinal beams 10, and the included angle between the supporting parts 42 on the same side is 50-70 degrees; the side of the supporting part 42 and the side of the reinforcing part 41 far away from the longitudinal beam extend outwards to form a flange 43. The added flanging can enhance the integral bending strength of the reinforcing component 40, and the included angle between the supporting parts 42 close to the same side of the longitudinal beam 10 is limited to be 50-70 degrees, so that the triangle formed by the reinforcing structure is close to an equilateral triangle, the stability of the equilateral triangle is stronger than that of other triangles, and the integral bending rigidity of the frame is higher.
Furthermore, the reinforcing assembly 40 further includes a reinforcing partition 44, the reinforcing partition 44 is used for connecting the reinforcing portion 41 and the flange 43 extending outwards from the supporting portion 42, and a through hole is formed in the middle of the reinforcing partition 44. Reinforcing spacers are provided to reinforce the overall strength of reinforcement assembly 40. In addition, the through-hole in the middle of the reinforcing spacer 44 serves to reduce the weight of the reinforcing member 40 while ensuring sufficient connection strength of the reinforcing member 40. Furthermore, the ends of the supporting portion 42 and the joints between the supporting portion 42 and the reinforcing portion 41 are all provided with round corners. These fillet bends are designed to increase the formability of the sheet metal part being manufactured so that the reinforcing component 40 of the sheet metal part can be more easily manufactured.
It should be noted that, the reason why the reinforcement assembly 40 is designed as an X-shaped cross beam of a sheet metal structure is that a battery motor and other related control systems need to be installed at the place where the reinforcement assembly 40 is located, and the cross beam of the sheet metal structure can provide a large number of mounting surfaces compared with a tubular X-shaped cross beam, and in addition, the reinforcement assembly 40 is lap-jointed with the longitudinal beam 10, and can be fixed specifically by riveting.
Referring to fig. 6 to 7, it is shown that the torsional deformation curves of the two side longitudinal beams 10 of the novel frame and the conventional frame are graphs of the Z-directional displacement of the longitudinal beams 10, and it can be known from the common knowledge that the Z-directional displacement is linearly related to the torsional angle, and the torsional angle is linearly related to the torsional rigidity (i.e. the smaller the Z-directional displacement is, the smaller the torsional angle is, the stronger the torsional rigidity is), and it can be intuitively known from the torsional deformation curves that the torsional rigidity of the longitudinal beam 10 is obviously improved by arranging the cross beam into an X-shaped cross beam, compared with the former long strip-shaped cross beam, and in addition, the displacement trends of the cross beam and the longitudinal beam 10 are consistent, and no curve graph is shown; therefore, obviously, the bending and torsion resisting rigidity of the whole frame is obviously improved, and the NVH performance of the whole vehicle is obviously improved. The Z direction refers to a direction perpendicular to the ground when the vehicle is traveling, the X direction refers to a direction of moving forward and backward when the vehicle is traveling, and the Y direction refers to directions on both the left and right sides when the vehicle is traveling.
Further, a front plate spring front support 14, a front plate spring rear support 15, a rear plate spring front support 16 and a rear plate spring rear support 17 are sequentially arranged on the outer side of the longitudinal beam main body 11. The leaf spring support is used for installing a leaf spring, and the leaf spring is used for connecting and fixing the frame and the automobile body. The position of leaf spring support depends on the holistic arrangement of vehicle and whole car mass decision, consequently need do extra enhancement in leaf spring support department in order to strengthen the joint strength of frame and automobile body, in addition, directly weld fixture with the automobile body for the frame, connect the vibration conduction that can reduce the frame through the leaf spring and to the automobile body, reduce whole car noise to improve the holistic NVH of car.
Specifically, the reinforcing component 40 is provided with the second cross beam 30 and the first cross beam 20 in sequence on one side close to the front cabin of the automobile, the two ends of the second cross beam 30 and the two ends of the first cross beam 20 are respectively connected with the longitudinal beam main bodies 11 of the two longitudinal beams 10, the second cross beam 30 and the first cross beam 20 are both C-shaped beams, the second cross beam 20 is further provided with reinforcing ribs 31, and the two sides of each reinforcing rib 31 extend outwards to form connecting portions used for connecting the side walls of the second cross beam 30. Furthermore, a large number of mounting surfaces are required here for the front ends of the longitudinal beams 10 to provide mounting locations for other parts of the vehicle (in addition, the mounting surfaces provided by the sheet metal parts of the X-shaped beams are not sufficient), so designing the first and second transverse beams 20, 30 as C-shaped beams can provide a large number of mounting surfaces without affecting the bending stiffness of the entire frame. In addition, the middle parts of the two ends of the second cross beam 30 and the reinforcing ribs 31 are inwards sunken to form U-shaped grooves, so that the structural strength of the two ends and the middle parts of the second cross beam 30 and the reinforcing ribs 31 are different to form a collapsing structure; the second cross beam 30 and the reinforcing ribs 31 are provided with crumple structures for absorbing energy, so that external force applied to the frame is reduced, and the integral bending resistance of the frame is strengthened in a phase change manner.
In addition, a third cross beam 50, a fourth cross beam 60 and a fifth cross beam 70 are sequentially arranged on one side, away from the automobile front cabin, of the reinforcing assembly 40, the third cross beam 50 is a tubular beam with two wide ends and a thin middle, two ends of the third cross beam 50 are respectively connected with the two longitudinal beam main bodies 11, the fourth cross beam 60 and the fifth cross beam 70 are respectively formed into an X-shaped structure by welding one ends of four tubular beams 61, and the other end of each tubular beam 61 is welded with the longitudinal beam main body 11. Since the third cross member 50 has a limited space, many other systems such as electronic and electric appliances are arranged therein, and no X-shaped beam is arranged in the space, the third cross member 50 is designed to be a tubular beam, and the two ends of the third cross member 50 are large to increase the welding area with the frame. The distance between the fourth cross member 60 and the fifth cross member 70 occupies two thirds of the length of the vehicle frame, so that the fourth cross member 60 and the fifth cross member 70 are designed into X-shaped beams, the bending rigidity of most regions of the vehicle frame can be improved, in addition, because the installation of automobile part equipment is not needed at the positions of the fourth cross member 60 and the fifth cross member 70, the fourth cross member 60 and the fifth cross member 70 can be formed by welding the tubular beams 61, and the bending and torsion resistance of the tubular beams is the best in various shapes.
Further, the included angle between the tubular beams 61 on the side, close to the longitudinal beam 10, of the fourth cross beam 60 is between 100 and 120 degrees; the included angle between the tubular beams 61 on the side of the fifth cross beam 70 close to the longitudinal beam 10 is between 80 ° and 90 °. In order to strengthen the connection strength between the leaf spring support and the vehicle frame, the joint of one end of the fourth cross beam 60 and the longitudinal beam 10 corresponds to the joint of the rear leaf spring front support 16 and the longitudinal beam 10, and the other end of the fourth cross beam 60 is close to the third cross beam 50 as much as possible, so that the included angle between the tubular beams 61 on the side of the fourth cross beam 60 close to the longitudinal beam 10 is 100-120 degrees. Furthermore, it can be understood that the connection between one end of the fifth cross beam 70 and the longitudinal beam 10 corresponds to the connection between the rear leaf spring rear support 17 and the longitudinal beam 10, and the other end of the fifth cross beam 70 is as close as possible to the rear end of the longitudinal beam 10, so that the included angle between the tube beams 61 on the side of the fifth cross beam 70 close to the longitudinal beam 10 is between 80 ° and 90 °.
In addition, a reinforcing rib 62 is arranged between the tubular beams 61 of the fourth beam 60 and the fifth beam 70, the reinforcing rib 62 is triangular, and two ends of the reinforcing rib 62 are respectively connected with the side walls of the tubular beams 61. The reinforcing ribs 62 are provided to reinforce the coupling strength between the tubular beams 61, thereby reinforcing the structural strength of the fourth and fifth cross members 60 and 70 as a whole.
Specifically, the width of the longitudinal beam 10 at both ends is smaller than the width of the longitudinal beam 10 at the middle section. The front end of the longitudinal beam 10 is downwards sunken to enable the Z-direction width of the front end of the longitudinal beam 10 to be smaller than the width of the middle section of the longitudinal beam 10, the front end of the longitudinal beam 10 is designed to avoid a cab, the tail end of the longitudinal beam 10 is upwards sunken to enable the Z-direction width of the tail end of the longitudinal beam 10 to be smaller than the width of the middle section of the longitudinal beam 10, and the tail end of the longitudinal beam 10 is designed to provide a rear suspension jumping space; and because the bending rigidity of the two ends of the longitudinal beam 10 has little influence on the bending rigidity of the whole frame, the bending rigidity of the whole frame cannot be influenced by the design.
It should be noted that, the connection between the cross beam and the longitudinal beam 10 is performed by welding except for the reinforcing assembly 40, the connection between the reinforcing rib 31 and the second cross beam 30 is also performed by welding, the connection between the reinforcing partition 44 and the turned-up edge 43 is also performed by welding, and the connection between the reinforcing rib 62 and the tubular beam 61 is also performed by welding. The specific welding mode can adopt carbon dioxide gas shielded arc welding.
