[0027] Reference will now be made to Figures 1-4 describe a vehicle body assembly 100 for a vehicle 200 according to a first aspect embodiment of the present application. It should be noted that in the description of the vehicle body assembly 100, a first direction (e.g., the left-right direction in Figure 1 , a second direction (e.g., the up-down direction in Figure 1 , and a third direction (e.g., the front-rear direction in Figure 1 are the length direction, the height direction, and the width direction of the vehicle body assembly 100, respectively.

[0028] As shown in Figures 1-4 , the vehicle body assembly 100 for the vehicle 200 according to the first aspect embodiment of the present application includes a rocker beam 1 and an elastic buffer 2.

[0029] Specifically, the rocker beam 1 extends along the first direction, and the elastic buffer 2 is movably connected with the rocker beam 1. The rocker beam 1 is an important component of the vehicle body assembly 100 and has very strong rigidity and strength, which can be used to ensure the safety of the vehicle body assembly 100. Specifically, on the one hand, the rocker beam 1 as a key load-bearing structure can provide support for the remaining components of the vehicle body assembly 100, enhancing the overall rigidity and stability of the vehicle body assembly 100; on the other hand, when the vehicle 200 is subjected to a side collision, the rocker beam 1 can absorb and disperse the impact force to protect the passengers.

[0030] For example, in the example of Figures 1-3 The elastic buffer 2 and the rocker beam 1 are movably connected, and from the perspective of the whole vehicle, the cargo box, the vehicle body assembly 100, and the suspension system are connected as a whole, thereby effectively improving the connection strength and rigidity of the vehicle 200. Meanwhile, the elastic buffer 2 is conducive to the connection and buffering effect of the cargo box and the suspension system at the rear of the vehicle body assembly 100. That is, the connection of the elastic buffer 2 and the rocker beam 1 can increase the overall rigidity of the vehicle body assembly 100, which is conducive to improving the stability of the vehicle 200 during high-speed driving or turning. On the other hand, when a collision occurs, the rocker beam 1 is part of the energy absorption of the vehicle body assembly 100, and the connection of the rocker beam 1 and the elastic buffer 2 can effectively disperse and absorb impact energy.

[0031] At the same time, compared with the installation mode of the traditional buffer, the above-mentioned vehicle body assembly 100 changes the force transmission mode, which is conducive to dispersing and transmitting the road load received by the elastic buffer 2 to the overall structure of the vehicle body assembly 100. Specifically, the complex load received by the elastic buffer 2 is transmitted to the rocker beam 1, forming a force transmission path of the vehicle body assembly 100 in the first direction, which is conducive to reducing vibration and improving the stability of the vehicle body assembly 100, and also plays a significant role in dispersing and absorbing impact force. In addition, the connection of the elastic buffer 2 and the rocker beam 1 is conducive to reducing the length of the force arm of the dynamic stiffness excitation load, thereby greatly improving the dynamic stiffness of the connection point of the elastic buffer 2 and the rocker beam 1 in the first direction.

[0032] According to the vehicle body assembly 100 for the vehicle 200, the elastic buffer 2 is movably connected to the rocker beam 1, which is conducive to increasing the overall rigidity of the vehicle body assembly 100 and improving the stability of the vehicle 200 during high-speed driving or turning. In addition, the force transmission mode is changed, the complex load received by the elastic buffer 2 is transmitted to the rocker beam 1, which is conducive to reducing vibration and improving the stability of the vehicle body, and also plays a significant role in dispersing and absorbing impact force.

[0033] According to some embodiments of the present application, referring to Figures 1-3 The elastic buffer 2 extends along the first direction, the elastic buffer 2 is located on one side of the rocker beam 1 along the second direction, and the elastic buffer 2 and the rocker beam 1 are movably connected to each other at one end. The arrangement of the rocker beam 1 and the elastic buffer 2 is relatively regular, fully utilizes the space on one side of the rocker beam 1 in the second direction, and is conducive to reducing the length and width of the vehicle body assembly 100. At the same time, the connection distance between the elastic buffer 2 and the rocker beam 1 is shortened, which is conducive to shortening the path of the acting force from the elastic buffer 2 to the rocker beam 1, thereby improving the force transmission efficiency, and the rocker beam 1 can effectively disperse the complex load transmitted by the elastic buffer 2, which is conducive to reducing vibration and improving the stability of the vehicle body.

[0034] According to some embodiments of the present application, referring to Figures 1-3 , the vehicle body assembly 100 for the vehicle 200 further comprises a mounting bracket 3, the mounting bracket 3 is arranged on the rocker beam 1, and the elastic buffer 2 is movably connected with the mounting bracket 3. In this way, the mounting bracket 3 is arranged to realize stable connection with the rocker beam 1, and the mounting bracket 3 is movably connected, thereby avoiding the direct connection of the rocker beam 1 with the elastic buffer 2, which affects the structural strength of the rocker beam 1. Therefore, the structural strength of the vehicle body assembly 100 is improved, and the service life of the vehicle body assembly 100 is prolonged.

[0035] For example, as shown in Figure 2 and Figure 3 , the mounting bracket 3 comprises a first bracket section 31 and a second bracket section 32. The first bracket section 31 is rotatably connected with the elastic buffer 2. The second bracket section 32 is arranged on the side of the first bracket section 31 away from the elastic buffer 2 and connected with the rocker beam 1. Therefore, the design of the first bracket section 31 and the second bracket section 32 is beneficial to improve the stability of the mounting bracket 3 connecting the elastic buffer 2 and the rocker beam 1, and to avoid the interference of the rocker beam 1 with the rotation of the elastic buffer 2.

[0036] Further, as shown in Figure 2 and Figure 3 , a groove 311 is formed on the first bracket section 31, and one end of the elastic buffer 2 is fitted in the groove 311. In this way, the connection position of the elastic buffer 2 and the first bracket section 31 is protected, and the remaining components or external impact directly acting on the connection position of the elastic buffer 2 and the first bracket section 31 is avoided, thereby improving the connection reliability of the elastic buffer 2 and the mounting bracket 3 and prolonging the service life of the elastic buffer 2 and the mounting bracket 3.

[0037] According to some embodiments of the present application, referring to Figure 2 and Figure 3 , the mounting bracket 3 and the rocker beam 1 are connected by fasteners 4, and a sleeve 5 is arranged at the fasteners 4. The vehicle body assembly 100 further comprises a sleeve mounting seat 6, the sleeve mounting seat 6 is arranged on the rocker beam 1, and the sleeve mounting seat 6 is connected with the sleeve 5. For example, along the first direction, the mounting bracket 3 and the rocker beam 1 are connected by two fasteners 4. The arrangement of the sleeve 5 is beneficial to disperse the load received by the fasteners 4 to a larger area, thereby reducing the concentration of local stress and improving the connection reliability of the mounting bracket 3 and the rocker beam 1.

[0038] The sleeve mounting seat 6 increases the penetrating thickness of the fastener 4, and the load of the fastener 4 on the mounting bracket 3 can be dispersed to a larger area through the sleeve 5 and the sleeve mounting seat 6, that is, the sleeve 5 can further transmit the load of the fastener 4 from the sleeve 5 to the sleeve mounting seat 6, thereby further dispersing the load and improving the connection stability of the mounting bracket 3 and the rocker beam 1. Thus, it is helpful to reduce the concentration of local stress and increase the reliability and stability of the fastener 4 connecting the mounting bracket 3 and the rocker beam 1. The sleeve mounting seat 6 and the sleeve 5 can be connected through welding points.

[0039] Further, referring to Figure 2 and Figure 3 , the rocker beam 1 includes a first beam plate 11 and a second beam plate 12 opposite each other in the second direction, and the sleeve mounting seat 6 is supported between the first beam plate 11 and the second beam plate 12. The sleeve mounting seat 6 can be supported between the first beam plate 11 and the second beam plate 12 as a reinforcing element to reinforce the local cavity weakness inside the rocker beam 1, effectively support the rocker beam 1, improve the structural rigidity of the first beam plate 11 and the second beam plate 12, and the integrity of the rocker beam 1 to increase the structural stability of the rocker beam 1.

[0040] According to some embodiments of the present application, referring to Figure 1 and Figure 4 , the vehicle body assembly 100 further includes a C-pillar 7 and a roof beam 8. The C-pillar 7 is connected to the rocker beam 1, and the C-pillar 7 extends in the second direction, and the C-pillar 7 is located on the side of the rocker beam 1 away from the elastic buffer 2 in the second direction. The roof beam 8 is connected to the side of the C-pillar 7 away from the elastic buffer 2 in the second direction. Thus, the roof beam 8, the C-pillar 7 and the rocker beam 1 are sequentially connected to form a ring-shaped whole, increasing the integrity of the vehicle body assembly 100, and the elastic buffer 2, the rocker beam 1, the C-pillar 7 and the roof beam 8 are collectively stressed, also increasing the dispersion options of the stress on the rocker beam 1. Specifically, the stress on the rocker beam 1 can be transmitted and dispersed along the extension direction of the C-pillar 7 and then transmitted to the roof beam 8 for dispersion. Thus, the load force is avoided to be concentrated, the local rigidity of the connection positions of the elastic buffer 2, the rocker beam 1, the mounting bracket 3, the C-pillar 7 and the roof beam 8 is improved, and the vibration and noise brought by the road surface are isolated to improve the riding comfort of the passengers, and the torsional rigidity of the entire vehicle body is improved.

[0041] Further, referring to Figure 4 , the vehicle body assembly 100 further includes a rear panel 9, the rear panel 9 is connected to the C-pillar 7, and the rear panel 9 extends in a third direction. The rear panel 9 is arranged to increase the dispersion area of the force acting on the C-pillar 7, to increase the dispersion of the force and avoid the deformation of the C-pillar 7 caused by the concentration of the force on the C-pillar 7, thereby improving the structural strength and torsional rigidity of the vehicle body assembly 100 and prolonging the service life of the vehicle body assembly 100.

[0042] According to some embodiments of the present application, referring to Figure 1 , the vehicle body assembly 100 further comprises a reinforcing beam 10, one end of the reinforcing beam 10 is connected with the rocker beam 1, and the other end of the reinforcing beam 10 extends obliquely away from the rocker beam 1. For example, the other end of the reinforcing beam 10 can be inclined towards the rear away from the rocker beam 1, thereby further guiding and dispersing the stress on the rocker beam 1 by the reinforcing beam 10, increasing the force transmission path, avoiding stress concentration of the elastic buffer 2 on the rocker beam 1, thereby facilitating to improve the torsional stiffness and structural strength of the rocker beam 1.

[0043] When subjected to bending or torsional load excitation, the force of the elastic buffer 2 is transmitted to the rocker beam 1 through the mounting bracket 3, and then dispersed through the reinforcing beam 10, thereby effectively dispersing the force to the reinforcing beam 10, and improving the overall deformation resistance of the vehicle body assembly 100.

[0044] Referring to Figure 1 , the vehicle body assembly 100 further comprises a side plate 101 connected with the reinforcing beam 10. The side plate 101 is a plate material installed around the cargo box of a truck, a truck or a container transport tool, used to protect the goods and ensure their secure fixing. The side plate 101 not only helps to maintain the integrity of the cargo box structure, but also plays a role in preventing the goods from being affected by the external environment during transportation, such as wind and rain invasion or foreign object collision. In this way, the dispersion area of the force received by the reinforcing beam 10 is increased. Specifically, when the vehicle body is subjected to bending and torsional load, the elastic buffer 2 can transmit the load to the cargo box, effectively changing the original force transmission mode of the side plate 101 directly pressing the C-pillar 7 to a ring-shaped force transmission mode of the overall structure of the cargo box-vehicle body assembly 100 and the suspension system, thereby greatly enhancing the deformation resistance of the vehicle body assembly 100.

[0045] Optionally, the reinforcing beam 10 can also be connected with the rocker beam 1 to increase the structural strength of the rocker beam 1. Through the reinforcing beam 10, the risk of deformation of the side plate 101 and the rocker beam 1 is reduced, and the service life of the side plate 101 and the rocker beam 1 is prolonged. At the same time, the elastic buffer 2, the rocker beam 1, the reinforcing beam 10 and the side plate 101 form a force transmission path. When subjected to bending or torsional load excitation, the force of the elastic buffer 2 is transmitted to the rocker beam 1 through the mounting bracket 3, and then dispersed to the side plate 101 through the reinforcing beam 10, and then dispersed to the cargo box structure matched with the side plate 101 through the side plate 101, thereby helping to improve the overall deformation resistance and energy absorption capacity of the vehicle body assembly 100.

[0046] In summary, the vehicle body assembly 100 changes the force transmission mode, which helps to disperse and transmit the road load received by the elastic buffer 2 to the rest of the vehicle body assembly 100, forming three effective force transmission paths as shown in Figure 1 First, the complex load received by the elastic buffer 2 can be transmitted to the rocker beam 1 through the mounting bracket 3, forming a first force transmission path in the first direction. Second, the connection of the elastic buffer 2 with the rocker beam 1, the sleeve mounting seat 6, the C-pillar 7, and the roof beam 8 forms a complete ring structure, thereby forming a second force transmission path. Finally, the design scheme that the elastic buffer 2 is connected with the side panel 101 through the rocker beam 1 and the reinforcing beam 10 forms the third force transmission path shown.

[0047] According to some embodiments of the present application, referring to Figure 2 and Figure 3 , the vehicle body assembly 100 for the vehicle 200 further comprises a longitudinal beam 102 extending in the first direction, the longitudinal beam 102 being arranged on one side of the rocker beam 1 in the third direction, and the bottom surface of the rocker beam 1 being lower than the bottom surface of the longitudinal beam 102. That is, on the same horizontal ground, the bottom surface of the rocker beam 1 is closer to the ground, while the bottom surface of the longitudinal beam 102 is farther from the ground. Since the height of the bottom of the rocker beam 1 from the ground is relatively low, and the height of the elastic buffer 2 from the ground is constant, connecting the elastic buffer 2 with the rocker beam 1 can reduce the height of the mounting bracket 3, thereby reducing the length of the force arm of the dynamic stiffness excitation load, effectively reducing the amount of rotation of the mounting bracket 3 in the second direction under periodic load, thus greatly reducing the displacement in the first direction at the load excitation site, significantly improving the dynamic stiffness of the mounting bracket 3 in the first direction, and facilitating the satisfaction of the dynamic stiffness performance requirement proposed by the NVH (Noise, Vibration, and Harshness) of the vehicle 200.

[0048] For example, as shown in Figure 2 and Figure 3 , the mounting bracket 3 is arranged between the elastic buffer 2 and the rocker beam 1, one end of the mounting bracket 3 is connected with the longitudinal beam 102 and the rocker beam 1, and the other end of the mounting bracket 3 is rotationally connected with the elastic buffer 2. The rocker beam 1 and the longitudinal beam 102 are arranged adjacent to each other in the third direction, which facilitates to increase the connection stability of the mounting bracket 3, thereby facilitating to increase the reliability of the mounting bracket 3 in connecting the longitudinal beam 102, the rocker beam 1, and the elastic buffer 2. The bottom surface of the rocker beam 1 is lower than the bottom surface of the longitudinal beam 102, which facilitates to limit the longitudinal beam 102 through the rocker beam 1, thereby avoiding deformation of the longitudinal beam 102. Optionally, the end of the mounting bracket 3 connected with the longitudinal beam 102 and the rocker beam 1 is designed in a stepped manner to correspond to the positions of the rocker beam 1 and the longitudinal beam 102, thereby facilitating to improve the reliability and stability of the mounting bracket 3 in connecting the longitudinal beam 102 and the rocker beam 1.

[0049] The elastic buffer 2 is a steel plate spring. The steel plate spring is a common automobile suspension system component, mainly used for carrying the weight of the vehicle 200 and absorbing the vibration caused by the uneven road surface during driving. The steel plate spring is composed of multiple high-strength steel sheets with different lengths, which are fixed together by a center bolt, and the two ends are usually fixed on the vehicle frame. Among them, the uppermost piece (called the main piece) of the multiple steel sheets of the steel plate spring is the longest, and each piece below gradually becomes shorter. This design allows the entire steel plate spring to bend to adapt to different loads and road conditions. The advantages of the steel plate spring include simple structure, low cost, and high load capacity. Therefore, using the steel plate spring as the elastic buffer 2 is beneficial to ensure the structural strength and service life of the elastic buffer 2.
