[0031] The accompanying drawings, which are included in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, are used to explain the principles of the present invention.

[0034] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0035] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0036] In this embodiment, the length direction of the frame refers to the X direction of the vehicle, the length direction of the vehicle refers to the X direction of the vehicle, the width direction of the vehicle refers to the Y direction of the vehicle, and the height direction of the vehicle refers to the Z direction of the vehicle.

[0037] The first embodiment of the utility model provides a vehicle, which includes a frame, wherein the frame includes two frame longitudinal beams 200 arranged at intervals, a plurality of frame cross beams respectively connected to the two frame longitudinal beams 200, and a frame sill beam 300 connected to a partial area outside the frame longitudinal beam 200. A radiator frame 100, a front floor assembly 400, and a rear floor assembly 500 are sequentially arranged along the length direction of the frame.

[0038] like Figure 1 and Figure 2As shown, the vehicle further includes a plurality of suspension assemblies sequentially arranged along the length direction of the frame, wherein the setting positions of at least some of the plurality of suspension assemblies in the vehicle length direction are determined based on the dynamic stiffness of the frame rocker beam 300, and the setting positions in the vehicle width direction are outside the frame longitudinal beam 200 and close to the frame rocker beam 300.

[0039] With respect to the installation position of each suspension component in the length direction of the frame, multiple points in the length direction of the frame are selected for dynamic stiffness analysis to determine the installation position of each suspension component. Specifically, for the area with the frame sill beam 300 in the length direction of the frame, the installation position of the suspension component is determined according to the dynamic stiffness of the frame sill beam 300, and the suspension component is set at the point with the maximum dynamic stiffness to ensure the dynamic stiffness requirement of the installation position of the suspension component. With respect to the installation position of each suspension component in the width direction of the vehicle, the suspension component is set as close to the outside of the vehicle as possible, which can reduce floor vibration and improve the stability of the vehicle.

[0040] In addition, suspension components are also installed on the radiator frame 100 at the front end of the frame and the rear cross beam assembly of the rear floor at the rear end of the frame. The installation position of the suspension component along the length direction of the vehicle is determined according to the dynamic stiffness of the frame longitudinal beam 200, and the setting position of the suspension component along the width direction of the vehicle is the outer side of the frame longitudinal beam 200.

[0041] The vehicle A-pillar, vehicle B-pillar, vehicle C-pillar and vehicle D-pillar are sequentially arranged along the length direction of the vehicle. In some embodiments, a plurality of suspension components are sequentially arranged from the front to the rear of the vehicle, and at least include a first suspension component 1 arranged near the radiator frame 100, a second suspension component 2 arranged corresponding to the vehicle A-pillar, a third suspension component 3 arranged corresponding to the vehicle B-pillar, a fourth suspension component 4 arranged corresponding to the vehicle C-pillar and a fifth suspension component 5 arranged corresponding to the vehicle D-pillar. Exemplarily, the first suspension component 1 is connected to the radiator frame 100, the second suspension component 2 is connected to the vehicle A-pillar, the third suspension component 3 is connected to the vehicle B-pillar, the fourth suspension component 4 is connected to the vehicle C-pillar, and the fifth suspension component 5 is connected to the vehicle D-pillar. Five groups of suspension components are arranged along the length direction of the frame, and the number of suspension components is large, which can improve the ride comfort of the vehicle. Among them, if the vehicle is an electric vehicle, the second suspension component 2, the third suspension component 3 and the fourth suspension component 4 are arranged along the same straight line, and the suspension components occupy a smaller space along the width direction of the vehicle (i.e., the Y direction of the vehicle), which can expand the installation space of the battery pack.

[0042] Among them, each suspension component is not arranged on the line connecting the two front wheels of the vehicle, and each suspension component is not arranged on the line connecting the two rear wheels of the vehicle, so as to achieve dispersed force and avoid concentrated force on a single suspension component.

[0043] In this embodiment, the frame longitudinal beam 200 has a front section, a middle section and a rear section, the first suspension assembly 1 and the second suspension assembly 2 are arranged in the front section, the third suspension assembly 3 is arranged in the middle section, and the fourth suspension assembly 4 and the fifth suspension assembly 5 are arranged in the rear section. The material of the frame is the same steel, and the elastic modulus can be regarded as having no obvious difference, so the main influencing factors of the modal are mass and structural stiffness. In order to ensure the structural stiffness, a reinforcing plate is provided inside the frame longitudinal beam 200. In addition, the bending vibration mode is also strongly related to the Z-direction height of the longitudinal beam, so the height of the middle section of the frame longitudinal beam 200 along the vehicle height direction (i.e., the vehicle Z direction) can be designed to ensure that the bending vibration mode meets the requirements. Further, the torsion and lateral bending vibration modes are strongly related to the stiffness of the overlap position, so the overlap positions of this frame are all overlapped in the vehicle width direction and / or vehicle height direction, and the weld coverage rate is close to 100%. The lateral bending vibration mode is also related to the strength of the frame in the vehicle width direction. The width of the frame longitudinal beam 200 in the vehicle width direction can be designed to ensure that the bending vibration mode meets the requirements.

[0044] In some embodiments, Figure 4 and Figure 5 As shown, the first suspension assembly 1 is arranged below the radiator frame 100 located at the front end of the vehicle frame through the first suspension mounting member, and the first suspension mounting member at least includes a first suspension mounting plate 11 and a first suspension reinforcing plate 12, and a barrel-shaped structure is formed between the first suspension mounting plate 11, the first suspension reinforcing plate 12 and the column 101. The first suspension mounting member is used to connect with the first suspension assembly 1. Among them, the first suspension mounting plate 11 and the first suspension reinforcing plate 12 are sequentially connected along the height direction of the vehicle to form an integral first suspension mounting member, and then connected to the bottom of the column 101, so that the column 101 and the first suspension mounting member form a barrel-shaped structure that is circumferentially closed and bottom-blocked, so as to ensure the dynamic stiffness requirements of the mounting point of the first suspension assembly 1.

[0045] Exemplarily, the first suspension mounting plate 11 and the first suspension reinforcement plate 12 are both made of ultra-high strength steel material.

[0046] In some embodiments, the second suspension assembly 2, the third suspension assembly 3 and the fourth suspension assembly 4 are arranged between the frame sill beam 300 and the frame longitudinal beam 200, specifically, arranged on the outside of the frame longitudinal beam 200 and arranged close to the frame sill beam 300, which is beneficial to reduce the vibration of the front floor.

[0047] like Figure 2 and Figure 3 As shown, the front floor assembly 400 includes a front floor mid-channel front cross beam 402, a connecting beam 403 and a front floor, wherein the left and right sides of the connecting beam 403 are respectively connected to the front floor mid-channel front cross beam 402 to support the front floor.

[0048] In some embodiments, Figure 6 and Figure 7 As shown, the second suspension assembly 2 is arranged at the front section of the frame sill beam 300, and the second suspension assembly 2 is respectively connected to the front cross beam 402 of the front floor mid-channel and the frame sill beam 300 in the vehicle width direction through the second suspension mounting member. The two ends of the second suspension mounting member are respectively connected to the front cross beam 402 of the front floor mid-channel and the frame sill beam 300, so as to ensure the dynamic stiffness requirement of the mounting point of the second suspension assembly 2, and at the same time, the second suspension assembly 2 is arranged close to the sill beam to reduce the vibration of the front floor.

[0049] Specifically, the second suspension mounting member is connected to the front floor front reinforcement plate 401 on the front floor middle channel front cross beam 402 and the sill beam front reinforcement plate 301 on the frame sill beam 300. The front floor front reinforcement plate 401 is located below the front floor and is used to strengthen the strength of the front floor assembly 400. The sill beam front reinforcement plate 301 is connected to the inner side of the frame sill beam 300 and plays a role in strengthening the strength of the frame sill beam 300. The second suspension mounting member includes a second suspension mounting plate 21, which is used to mount the second suspension assembly 2. The second suspension mounting plate 21, the front floor front reinforcement plate 401, the second suspension mounting plate 21 and the sill beam front reinforcement plate 301 are sequentially arranged and connected to form an integral structure along the vehicle height direction, and the integral structure is then respectively connected to the front floor middle channel front cross beam 402 and the frame sill beam 300 along the vehicle width direction to ensure the dynamic stiffness of the installation position of the second suspension assembly 2.

[0050] The front floor assembly 400 also includes a front floor cross member connected to the frame longitudinal beam 200, such as Figure 3 As shown, a front floor beam connecting plate 404 is connected to one side of the front floor beam. The front floor beam connecting plate 404 and the front floor front reinforcing plate 401 are located at different positions in the length direction of the frame, respectively supporting different positions of the front floor to enhance the strength.

[0051] In some embodiments, Figure 8 As shown, the third suspension component 3 is arranged in the middle section of the frame rocker beam 200, the third suspension component 3 is connected to the front floor crossbeam in the vehicle height direction through the third suspension mounting component, and the third suspension component 3 is connected to the frame rocker beam 300 in the vehicle width direction through the third suspension mounting component, so as to ensure the dynamic stiffness requirements of the third suspension component 3.

[0052] Specifically, the third suspension mounting member at least includes a third suspension mounting plate 31 and a third suspension reinforcement plate connected to each other. The third suspension mounting plate 31 and the third suspension reinforcement plate are connected to the front floor crossbeam connecting plate 404 on the front floor crossbeam and the sill beam middle reinforcement plate 302 on the frame sill beam 300. The sill beam middle reinforcement plate 302 is connected to the lower section of the vehicle B-pillar. Among them, the third suspension reinforcement plate is connected to one side of the third suspension mounting plate 31 and the two are arranged in sequence along the height direction of the vehicle. The third suspension reinforcement plate plays a role in strengthening the strength of the third suspension mounting plate 31. After the third suspension mounting plate 31 and the third suspension reinforcement plate are connected, the whole is connected to the front floor crossbeam connecting plate 404 and the sill beam middle reinforcement plate 302. The sill beam middle reinforcement plate 302 is arranged on the outer side of the frame sill beam 300, so that the structural strength of the frame sill beam 300 is improved. The third suspension mounting member is connected to the sill beam middle reinforcement plate 302 on the sill beam as a whole to ensure the dynamic stiffness requirements of the mounting point of the third suspension.

[0053] In some embodiments, Figure 3 As shown, the rear floor assembly 500 includes a rear floor middle cross beam 501, which is used to support the rear floor and strengthen the strength of the rear floor area. The two ends of the rear floor middle cross beam 501 are connected to the inner side of the frame sill beam 300.

[0054] In some embodiments, Figure 8 As shown, the fourth suspension component 4 is arranged at the rear section of the frame rocker beam 300. The fourth suspension component 4 is connected to the rear floor middle cross beam 501 in the vehicle height direction and to the rear section of the frame rocker beam 300 in the vehicle width direction through the fourth suspension mounting member to ensure the dynamic stiffness requirements of the mounting point of the fourth suspension component 4.

[0055] Specifically, the fourth suspension mounting member includes a fourth suspension mounting plate 41 and a fourth suspension reinforcing plate which are sequentially connected along the height direction of the vehicle, and the two are connected so that the fourth suspension mounting member has a higher structural rigidity.

[0056] like Figure 3 and Fig. 9 As shown, the rear floor assembly 500 further includes a rear floor rear cross beam assembly, which includes a rear floor rear cross beam 502 and a rear floor rear cross beam reinforcement plate 503 arranged at intervals along the height direction of the vehicle, and the rear floor rear cross beam reinforcement plate 503 is used to strengthen the strength of the rear floor rear cross beam 502. Both ends of the rear floor rear cross beam 502 are connected to the frame longitudinal beam 200. Exemplarily, the rear floor rear cross beam reinforcement plate 503 is arranged above the rear floor rear cross beam 502.

[0057] In some embodiments, the fifth suspension component 5 is disposed at the rear of the vehicle frame, and the fifth suspension component 5 is connected to the rear floor rear cross beam assembly through a fifth suspension mounting member to ensure the dynamic stiffness of the mounting point of the fifth suspension component 5 .

[0058] Specifically, the fifth suspension mounting member includes a fifth suspension mounting plate 51 and a fifth suspension reinforcement plate sequentially connected along the vehicle height direction, and the fifth suspension reinforcement plate is used to strengthen the strength of the fifth suspension mounting plate 51. The fifth suspension mounting plate 51 is connected to one end of the rear floor rear cross beam reinforcement plate 503 after being connected to the fifth suspension.

[0059] In addition, on the basis of making the second suspension component 2, the third suspension component 3 and the fourth suspension component 4 as close to the outside as possible, it is also necessary to ensure that there is a certain distance between them and the frame sill beam 300, so that when installing the bolts in each suspension component, the installation tool can extend from the gap between the frame sill beam 300 and the frame longitudinal beam 200. Exemplarily, the distance between the installation points of the second suspension component 2, the third suspension component 3 and the fourth suspension component 4 and the frame sill beam 300 is 50-80mm.

[0060] The first suspension mounting member, the second suspension mounting member, the third suspension mounting member, the fourth suspension mounting member and the fifth suspension mounting member further include a mounting bracket, which is connected to each suspension component and then connected to the frame longitudinal beam 200 to improve the mounting structure stability of each suspension component.

[0061] In addition, the position of each suspension assembly along the height direction of the vehicle is determined according to the gap between the cab and the ground.

[0062] In some embodiments, the first suspension assembly 1, the third suspension assembly 3 and the fourth suspension assembly 4 are compression type suspensions, and the second suspension assembly 2 and the fifth suspension assembly 5 are shear type suspensions. Specifically, the first suspension assembly 1, the third suspension assembly 3 and the fourth suspension assembly 4 are more likely to produce vertical deformation when subjected to force at the installation points, and the second suspension assembly 2 and the fifth suspension assembly 5 are more likely to undergo lateral deformation after subjected to force at the installation points. Among them, since the first-order vertical bending vibration mode at the first suspension assembly 1 and the third suspension assembly 3 is mainly in the vehicle height direction (Z direction), and the first-order torsion and vertical bending vibration mode at the fourth suspension assembly are also mainly in the vehicle height direction (Z direction), therefore, the first suspension assembly 1, the third suspension assembly 3 and the fourth suspension assembly 4 can be selected as compression type suspensions that can provide greater vertical stiffness, so that the vibrations of the engine and vehicle body during operation and driving can be better filtered at the above positions, and the cost can be controlled. The first-order lateral bending vibration mode of the second suspension assembly 2 and the fifth suspension assembly 5 is mainly in the vehicle width direction (Y direction), so the second suspension assembly 2 and the fifth suspension assembly 5 are selected as shear type suspensions that can provide greater lateral stiffness. In addition, the two second suspension assemblies 2 and the two fifth suspension assemblies 5 form a rectangular structure in space, which ensures the stability of the passenger cabin and is conducive to improving the stability performance of the vehicle during driving and turning.

[0063] The more suspension components there are, the more conducive it is for the frame to disperse the load of the vehicle body, but at the same time it will increase the transmission path of the noise. According to the different contributions of the road noise path, the key suspension components that affect the road noise are the second suspension component 2, the third suspension component 3 and the fourth suspension component 4; therefore, keeping the total stiffness unchanged and reducing the dynamic stiffness of the second suspension component 2, the third suspension component 3 and the fourth suspension component 4, the road noise will be reduced accordingly, and the NVH performance can be guaranteed. In addition, setting up multiple suspension components can improve the smoothness of the vehicle.
