[0040] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0041] It should also be noted that the front, rear, left, right, up and down directions mentioned in this embodiment, unless otherwise specified, are all based on the corresponding directions of the vehicle as reference standards. For example, the front and rear are the two ends of the vehicle in the length direction, the left and right are the two ends of the vehicle in the width direction, and the up and down are the two ends of the vehicle in the height direction. They will not be repeated later.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a chassis system integrated installation structure, including: a frame upper plate 1, a frame lower plate 2, a frame inner plate 3, a frame outer plate 4 and a plurality of installation columns 5; wherein, the middle portion of the frame upper plate 1 is provided with a Figure 1The first opening 111 is provided through it in the up and down directions as shown; the frame lower plate 2 is arranged at intervals below the frame upper plate 1, and a second opening 211 is provided through it in the vehicle height direction corresponding to the first opening 111; the frame inner plate 3 is arranged between the frame upper plate 1 and the frame lower plate 2, and is arranged around the circumference of the first opening 111 and the second opening 211, and the upper end face and the lower end face of the frame inner plate 3 are respectively fixedly connected to the frame upper plate 1 and the frame lower plate 2 by welding; the frame outer plate 4 is arranged between the frame upper plate 1 and the frame lower plate 2, and is arranged around the circumferential outside of the frame inner plate 3, and the upper end face and the lower end face of the frame outer plate 4 are respectively fixedly connected to the frame upper plate 1 and the frame lower plate 2 by welding, so as to form a closed cavity between the frame outer plate 4 and the frame inner plate 3; at this time, the frame upper plate 1, the frame lower plate 2, the frame inner plate 3, the frame The outer plate 4 encloses a plate-type frame platform with a closed cavity, and the first opening 111 and the second opening 211 also form an open space for chassis system components to pass through. By providing a number of mounting holes 6 / 6' suitable for external connection to chassis system components on the frame upper plate 1 and / or the frame lower plate 2, the chassis system components can be placed and installed; the mounting column 5 is arranged in the closed cavity, and the upper and lower ends of the mounting column 5 are fixedly connected to the frame upper plate 1 and the frame lower plate 2 by circumferential welding, so as to provide axial support in the closed cavity and realize torque transmission between the frame upper plate 1 and the frame lower plate 2; the mounting holes 6 / 6' are arranged corresponding to the mounting columns 5, and the mounting columns 5 can be used to provide axial support for the mounting holes 6 / 6', so that the frame upper plate 1 and the frame lower plate 2 can jointly share the axial force exerted on the mounting holes 6 / 6'. In this way, it can not only effectively bear the load of chassis system components, but also reduce the weight of the structure. At the same time, the overall structure only needs to be made by sheet metal bending and welding technology combined with machining. The structure is simple and the molding difficulty is low, which can effectively reduce development costs and manufacturing costs.

[0043] It is understandable that if Figure 2 As shown, in this embodiment, the frame inner panel 3 can be formed by connecting two left and right strips of sheet metal end-to-end, using methods including but not limited to welding. Compared to using a single strip of sheet metal connected end-to-end to enclose the circumference of the opening, this facilitates bending and machining, improves material utilization, and reduces material costs. Similarly, the frame outer panel 4 can also be formed by connecting two left and right strips of sheet metal end-to-end, achieving the same beneficial effects as the structure of the frame inner panel 3, and will not be further described here.

[0044] It is also understandable that the number and orientation of the mounting holes 6 / 6' and the mounting posts 5 can be set and adjusted according to the installation requirements of the chassis system components, for example. Figures 2 to 7As shown, in this embodiment, the chassis system integrated mounting structure is configured with 14 groups of mounting holes 6 / 6' and mounting columns 5 as mounting points for corresponding components, of which 2 groups can be used as mounting points for the left suspension assembly 100, namely the left suspension mounting point 101, which is located on the left side of the front of the opening space; 2 groups can be used as mounting points for the right suspension assembly 200, namely the right suspension mounting point 201, which is located on the right side of the front of the opening space; 4 groups can be used as mounting points for the rear suspension assembly 300, namely the rear suspension mounting point 301, which is located in the middle of the rear of the opening space; 2 groups can be used as mounting points for the steering gear assembly 400, namely the steering gear mounting point 401, which is located in the middle of the rear of the opening space; Mounting points 401 are located on the left and right sides of the rear opening. Two sets of left-side mounting points for the stabilizer bar assembly 500, namely the stabilizer bar left-side mounting points 501, are located on the left side of the rear opening. Two sets of right-side mounting points for the stabilizer bar assembly 500, namely the stabilizer bar right-side mounting points 502, are located on the right side of the rear opening. These can be used to install the suspension system, steering system, and suspension system. For the rear suspension assembly 300, rear suspension mounting bases 15 can be further welded to the four sets of rear suspension assembly 300 mounting points to optimize torque transmission between the four sets of rear suspension assembly mounting points. In other embodiments, the design can be increased or decreased based on the installation requirements of chassis system components, thereby improving the universality of the chassis system integrated installation structure.

[0045] In some embodiments, as Figures 2 to 4 As shown, the mounting post 5 can be a hollow cylinder, with mounting holes 6 / 6' corresponding to the through-holes of the mounting post 5 provided on the frame upper plate 1 and the frame lower plate 2. In this way, connecting bolts can be passed through the hollow mounting post 5 and penetrated into the frame upper plate 1 and the frame lower plate 2, achieving a stable connection with bilateral fixation. In other embodiments, the mounting post 5 can be a nut cylinder, i.e., one end has a threaded hole and the other end is solid, with mounting holes 6 / 6' corresponding to the threaded holes of the mounting post 5 provided on the frame upper plate 1 or the frame lower plate 2. This is suitable for single-sided fixation of chassis system components on the frame upper plate 1 or the frame lower plate 2.

[0046] In some embodiments, as Figure 1 and Figure 2 As shown, the frame upper plate 1 includes an integrally formed upper plate body 11, two connecting portions 12 and two longitudinal beam portions 13. The first opening 111 is opened in the upper plate body 11; the two connecting portions 12 are in the vehicle width direction ( Figure 1The two longitudinal beams 13 are symmetrically arranged on either side of the upper plate body 11 (in the left-right direction shown), and are bent upward and extended outwardly along the vehicle height direction from both sides of the upper plate body 11. The two longitudinal beams 13 are symmetrically arranged on the opposite outer sides of the two connecting portions 12 in the vehicle width direction, and are bent outward and extended from the outer sides of the connecting portions 12 along the vehicle width direction. The connection portions 12 and longitudinal beams 13 enable the upper plate body 11 to be used as a sunken platform for the placement of chassis system components, so that the plate frame platform they form can replace the subframe to meet the installation requirements of chassis system components. Furthermore, both the connection portions 12 and longitudinal beams 13 can be formed by bending an integral sheet metal part, resulting in a simple structure, low molding difficulty, and high manufacturing efficiency.

[0047] Furthermore, if Figure 2 and Figure 7 As shown, the connecting portion 12 includes a plurality of connecting segments 121, and the plurality of connecting segments 121 are arranged along the vehicle length direction ( Figure 1 The connecting sections 121 are spaced apart (in the front-to-back direction as shown) to create gaps 122 between adjacent connecting sections 121 for the steering system to pass through. This gap 122 not only facilitates the passage of the steering system or other chassis components, but also reduces the material usage of the connecting section 12, further reducing the structural weight and contributing to a lighter vehicle.

[0048] In some embodiments, as Figure 1 and Figure 2 As shown, the frame upper plate 1 also includes a wheel bag support portion 14 integrally formed on the longitudinal beam portion 13, and the wheel bag support portion 14 is bent and extended upward from the outer side of the longitudinal beam portion 13 along the vehicle height direction; the chassis system integrated installation structure also includes two wheel bag portions 7, and the two wheel bag portions 7 are extended along the vehicle length direction and symmetrically distributed on both sides of the upper plate body 11 in the vehicle width direction; wherein, the wheel bag portion 7 is fixedly connected to the front end of the wheel bag support portion 14 at one end in the vehicle length direction, and the other end extends backward along the vehicle length direction through the wheel bag support portion 14, the longitudinal beam portion 13, the connecting portion 12 and the upper plate body 11 to be connected to the frame outer plate 4, and is fixedly connected to the wheel bag support portion 14, the longitudinal beam portion 13, the connecting portion 12, the upper plate body 11 and the frame outer plate 4 in its extension path by welding. By setting the wheel bag part 7 and the wheel bag support part 14, the structural stability of the frame upper plate 1 can be further improved. At the same time, the wheel bag part 7 is welded to the frame upper plate 1 after bending, which not only has low molding difficulty and high manufacturing efficiency, but also can integrate the relevant functions of the wheel bag part 7 into the frame upper plate 1, thereby improving the degree of integration of the product.

[0049] Furthermore, if Figure 1 、 Figure 2 and Figure 8As shown, the wheel bag portion 7 is bent upward in the middle to form an arched raised section 71, and the upper end surface of the arched raised section 71 is provided with a shock absorber mounting hole 72 for the shock absorber assembly 700 to pass through; by providing the arched raised section 71, the bearing capacity of the wheel bag portion 7 at this location can be effectively improved to meet the arrangement and installation of the shock absorber assembly 700; preferably, the chassis system integrated mounting structure also includes a shock absorber mounting seat 73, and the shock absorber mounting seat 73 can be arranged in a circle around the shock absorber mounting hole 72 and fixedly connected to the upper end surface of the arched raised section 71 by welding. At this time, the arched raised section 71 can be regarded as a shock absorber tower. By integrating the shock absorber tower into the wheel bag portion 7, the integration of the frame upper plate 1 can be further improved, the number of independent components can be reduced, and it is beneficial to lightweight and less-componented vehicle body.

[0050] In some embodiments, as Figure 1 、 Figure 2 and Figure 8 As shown, the chassis system integrated installation structure also includes two swing arm mounting seats 81 symmetrically distributed in the vehicle width direction and two swing arm mounting brackets 82 symmetrically distributed in the vehicle width direction. The two swing arm mounting seats 81 are respectively fixedly connected to the circumferential sides of the frame outer panel 4, and the fixed connection method can be welding or bolt connection. Preferably, at least one connection section 121 corresponding to the connection part 12 is bolted to the frame outer panel 4 and the frame lower panel 2 to optimize the direction of torque transmission; the two swing arm mounting brackets 82 are respectively arranged on the circumferential sides of the frame outer panel 4 corresponding to the swing arm mounting seat 81, and are fixedly connected to the longitudinal beam part 13 on one side by welding, and are fixedly connected to the wheel bag part 7 on the other side by welding; an accommodating space for the swing arm assembly 600 is reserved between the swing arm mounting seat 81 and the swing arm mounting bracket 82. By setting the swing arm mounting seat 81 and the swing arm mounting bracket 82, the integration of the chassis system integrated mounting structure can be further improved, the number of independent components can be reduced, and it is beneficial to the lightweight and reduced number of parts of the vehicle body; at the same time, the swing arm mounting bracket 82 can also provide secondary connection support for the wheel bag part 7 and the longitudinal beam part 13 to improve the structural stability of the frame upper plate 1.

[0051] It is understandable that the swing arm mounting bracket 82 can be used as an independent mounting point at the other end of the swing arm assembly 600 to independently realize the connection with the other end of the swing arm assembly 600; it can also be used as a branch mounting point at the other end of the swing arm assembly 600 to cooperate with the frame upper plate 1 or the frame lower plate 2 to realize the connection with the other end of the swing arm assembly 600, for example, Figure 7 and Figure 8As shown, the other end of the swing arm assembly 600 can be connected to the swing arm mounting bracket 82 on one side in the vehicle width direction, and connected to the frame upper plate 1 on the other side in the width direction, so as to further improve the connection stability of the swing arm assembly 600; at the same time, when the other end of the swing arm assembly 600 is connected to the frame upper plate 1, it is preferably to share the mounting point with the stabilizer bar assembly 500, thereby reducing the opening of the mounting through hole 6 / 6'.

[0052] In some embodiments, as Figure 1 、 Figure 5 and Figure 7 As shown, the frame lower plate 2 includes an integrally formed lower plate body 21 and a floor portion 22, a second opening 211 is opened in the lower plate body 21, and the frame inner plate 3 and the frame outer plate 4 are enclosed between the lower plate body 21 and the upper plate body 11 to form a plate frame platform with a closed cavity; the floor portion 22 is arranged on the rear side of the lower plate body 21 in the length direction of the vehicle, and is extended backward from the rear side of the lower plate body 21 along the length direction of the vehicle to facilitate overlap with the middle frame of the vehicle body; the side of the lower plate body 21 close to the floor portion 22 is bent upward to form a convex step 212 extending along the width direction of the vehicle. The convex step 212 can be used to reduce the axial length of the mounting column 5 arranged therein and improve its supporting capacity on the one hand, and can also effectively improve the bending and torsional stiffness of the place and reduce the risk of deformation.

[0053] In some embodiments, as Figure 1 as well as Figures 3 to 7 As shown, the chassis system integrated mounting structure also includes a plurality of reinforcing ribs 9. These ribs 9 are connected to the opposing inner side surfaces of the bends and / or angles of various components of the chassis system integrated mounting structure and are spaced apart along the axis of the bends or angles. The arrangement of these ribs 9 enhances the overall structural strength and durability of the chassis system integrated mounting structure.

[0054] Specifically, if Figures 3 to 7 As shown, the aforementioned reinforcing ribs 9 can be arranged at the bends between the wheel support portion 14 and the longitudinal beam portion 13, the bends between the longitudinal beam portion 13 and the connecting portion 12, and the bends between the connecting portion 12 and the upper plate body 11; they can also be arranged at the fixed connection between the frame lower plate 2 and the frame outer plate 4, and at the fixed connection between the frame upper plate 1 and the frame outer plate 4; they can also be arranged at the fixed connection between the wheel package portion 7 and the wheel package support portion 14, and at the bend between the wheel package portion 7 and the arched raised section 71. It is understood that the aforementioned reinforcing ribs 9 can be cut and formed and then welded to the corresponding connecting surfaces. Their number and thickness can also be set according to the design requirements of specific parts or simulation results, and are not specifically limited here.
