The under-beam is arranged in multiple, which can further increase the reliability of the arrangement of the frame structure, increase the force transmission channel and improve the collision force transmission dispersion effect, and at the same time, the multiple under-beams also help to improve the rigidity of the middle part of the vehicle body.

[0024] In addition, the seat mounting bracket corresponding to the under-beam is arranged above the front floor panel, which can meet the needs of vehicle seat installation while saving the seat cross beam arranged above the front floor panel, helps to reduce the weight and cost of the vehicle body, and is also conducive to the arrangement of wire harnesses and air conditioning ducts in the vehicle cabin.

[0051] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0052] Embodiment one

[0053] This embodiment relates to a vehicle body structure, which is structurally associated with a front subframe and a battery pack, and is beneficial to improve the safety performance of the whole vehicle.

[0054] Overall structure, in combination Figures 1 to 3 As shown in the figure, the vehicle body structure of the embodiment comprises a frame structure 1 located below the front floor panel 2. The frame structure 1 is connected between the rocker beams 3 on the left and right sides, a battery pack mounting area s is formed in the frame structure 1, and a battery pack mounting point 101 is arranged on the frame structure 1, and the front part of the frame structure 1 is provided with a subframe mounting point 102 for mounting the front subframe 4.

[0055] As arranged above, the vehicle body structure of the embodiment can effectively associate the front subframe 4 and the battery pack 8 together in structure by mounting the battery pack 8 on the frame structure 1 and connecting the front part of the frame structure 1 with the front subframe 4, provide a continuous force transmission channel between the front subframe 4 and the battery pack 8, so that the collision force can be effectively transmitted along the front subframe 4 and the battery pack 8, and at the same time, the rigidity of the vehicle body structure can also be improved by connecting the front subframe 4 with the frame of the battery pack 8, thereby being beneficial to improve the safety performance of the whole vehicle.

[0056] Based on the above overall introduction, still referring to Figures 1 to 3As shown, specifically, the rear end of each rocker beam 3 is connected with a rear floor longitudinal beam 11 respectively, and the rear floor longitudinal beams 11 are connected with a rear floor cross beam 10, and the frame structure 1 of the embodiment is located in front of the rear floor cross beam 10, occupying a smaller space in the vehicle body.

[0057] For the specific structure of the frame structure 1, the frame structure 1 of the embodiment includes frame longitudinal beams 103 arranged on the left and right sides, a front cross beam 104 connected with the front end of the frame longitudinal beams 103, and a rear cross beam 105 connected with the rear end of the frame longitudinal beams 103. Each side frame longitudinal beam 103 is located on the inner side of the same side rocker beam 3, the front cross beam 104 and the rear cross beam 105 are connected between the two side rocker beams 3, and the front cross beam 104, the rear cross beam 105 and the two side frame longitudinal beams 103 define a battery pack mounting area s. The frame structure 1 is composed of the left and right frame longitudinal beams 103, the front cross beam 104 and the rear cross beam 105, which is simple in structure and easy to design and manufacture. Secondly, the rectangular frame structure 1 can adapt to the shape of the conventional battery pack 8, which is beneficial to improve the utilization rate of the space in the vehicle. The battery pack 8 is assembled in the frame structure 1, and the frame structure 1 plays a role in protecting the battery pack 8.

[0058] For example, referring to Figure 1 and Figure 2 As shown, the battery pack 8 and the frame structure 1 are connected by screwing, the battery pack mounting point 101 is arranged on the two frame longitudinal beams 103 and the rear cross beam 105, and the form of the battery pack mounting point 101 is an installation sleeve arranged on the frame structure 1. The installation direction of the battery pack 8 is upward assembly, that is, moving from the lower part of the vehicle body to the battery pack mounting area s, and then using bolts to fix and install the battery pack 8 on the frame longitudinal beams 103 and the rear cross beam 105. It should be noted that the battery pack mounting point 101 can also be arranged on the front cross beam 104, and in specific implementation, the battery pack mounting point 101 can be arranged on the front cross beam 104, the frame longitudinal beam 103 and the rear cross beam 105 as needed. It should be noted that the specific form of the battery pack mounting point 101 can also be other forms outside the installation sleeve, and the installation direction of the battery pack 8 can also be other directions.

[0059] For example, referring to Figures 2 to 4As shown, the left and right ends of the front cross beam 104 are bifurcated, and have a first connecting arm 1041 and a second connecting arm 1042. Each side first connecting arm 1041 is connected with the same side rocker beam 3, and each side second connecting arm 1042 is connected with the same side torsion box 7. The bifurcated ends of the front cross beam 104 are connected with the rocker beam 3 and the torsion box 7 respectively, which can increase the reliability of the connection between the front cross beam 104 and the surrounding components in the vehicle body, and improve the stability of the overall frame structure 1 in the vehicle body.

[0060] Secondly, as the structure optimization of the front cross beam 104, referring to Figure 3 As shown, from the top-down direction of the vehicle, the middle part of the front cross beam 104 is arched forward relative to the two ends. The arched forward setting of the middle part of the front cross beam 104 can increase the structural strength of the front cross beam 104 itself, and is also conducive to the transmission of the collision force to the rocker beam 3 and other positions on both sides. The arched forward setting of the middle part of the front cross beam 104 has a larger longitudinal cross-sectional size than the two ends. During vehicle driving, the internal stress of the front cross beam 104 is more concentrated in the middle part, and the larger cross-sectional size can effectively improve the bending and torsional resistance of the middle part of the front cross beam 104.

[0061] In addition, in order to improve the connection strength between the frame longitudinal beam 103 and the vehicle body, referring to Figure 2 and Figure 4 As shown, the front end of each side frame longitudinal beam 103 is located below the same side rear section 51 of the front engine compartment longitudinal beam and is connected together with the same side rear section 51 of the front engine compartment longitudinal beam. The connection of the frame longitudinal beam 103 with the same side rear section 51 of the front engine compartment longitudinal beam can form a continuous force transmission channel extending in the front-rear direction of the vehicle, which is conducive to the transmission and dispersion of the collision force in the vehicle body. The front engine compartment longitudinal beam 5 plays an important role in load transmission in the load-bearing vehicle body. The connection of the frame longitudinal beam 103 of the frame structure 1 with the rear end of the front engine compartment longitudinal beam 5 is equivalent to increasing the force transmission path between the front engine compartment longitudinal beam 5 and the rocker beam 3, and assisting the front engine compartment longitudinal beam 5 to transmit the collision force to the rocker beam 3 for dispersion and dissipation.

[0062] Preferably, regarding the arrangement of the sub-frame mounting point 102, referring to Figure 3 and Figure 4As shown, the subframe mounting points 102 are located on the front cross beam 104, and a plurality of subframe mounting points 102 are arranged on the front cross beam 104, and at least at some of the subframe mounting points 102, the front subframe 4, the front cross beam 104 and the rear section of the front engine bay longitudinal beam 51 are connected together. The specific form of the subframe mounting points 102 can be, for example, a mounting sleeve arranged in the front cross beam 104, and the rear end of the front subframe 4 is bolted in the mounting sleeve to complete the connection of the front subframe 4 and the front cross beam 104.

[0063] By connecting the front subframe 4, the front cross beam 104 and the rear section of the front engine bay longitudinal beam 51 together, the front subframe 4, the frame structure 1 and the front engine bay longitudinal beam 5 are connected into an organic whole, which can increase the stability of the arrangement of the front subframe 4 and the frame structure 1 in the vehicle body, and is also conducive to the transmission of the collision force at the front subframe 4 to the frame structure 1 and other peripheral vehicle body components. Secondly, the connection of the front subframe 4, the frame structure 1 and the front engine bay longitudinal beam 5 together shortens the force transmission path on the front cross beam 104 between the front engine bay longitudinal beam 5 and the front subframe 4, which can enable the collision force to be quickly transmitted between the front engine bay longitudinal beam 5 and the front subframe 4, and reduce the stress generated on the front cross beam 104 during the transmission.

[0064] In specific implementation, mounting sleeves can also be arranged in the rear section of the front engine bay longitudinal beam 51, and the front subframe 4, the front cross beam 104 and the rear section of the front engine bay longitudinal beam 51 are connected together by bolts. At the subframe mounting points 102 where the front subframe 4, the front cross beam 104 and the rear section of the front engine bay longitudinal beam 51 are connected together, the rear section of the front engine bay longitudinal beam 51, the front cross beam 104 and the front subframe 4 are arranged in sequence from top to bottom. The three subframe mounting points 102 in the embodiment are arranged in a group, and each group is symmetrically arranged on the left and right sides of the front cross beam 104.

[0065] Preferably, in order to further improve the connection reliability of the frame structure 1 and the vehicle body, referring to Figs. 1 and 2, Figure 2 and Figure 4 As shown, the vehicle body structure further comprises a lower cross beam 6 arranged below the front floor panel 2. The lower cross beam 6 is connected between the two side rocker beams 3 and arranged above the two side frame longitudinal beams 103, and the two side frame longitudinal beams 103 and the lower cross beam 6 are connected together. By arranging the lower cross beam 6 and connecting it with the two side frame longitudinal beams 103, on the one hand, the reliability of the arrangement of the frame structure 1 in the vehicle body can be improved, and the overall stiffness of the vehicle body is improved, and on the other hand, a force transmission channel can be added between the frame structure 1 and the rocker beams 3, which is conducive to improving the transmission and dispersion effect of the collision force.

[0066] The lower crossbeams 6 consist of multiple beams spaced apart along the front-rear direction of the vehicle, each connected to the longitudinal beams 103 of the side frames. This arrangement of multiple lower crossbeams 6 increases the reliability of the frame structure 1, expands the force transmission channels, and improves the dispersion of collision force. The multiple lower crossbeams 6 also contribute to increased rigidity in the middle of the vehicle body. In a frontal collision, the force is transmitted from the front engine compartment longitudinal beam 5, through the frame structure 1, to the sill beam 3 and the lower crossbeams 6. In a side collision, the force is transmitted from the sill beam 3, through the lower crossbeams 6 and the frame structure 1, and then outwards to the periphery. The frame structure 1 serves both as a protective frame for the battery pack 8 and as a force transmission mechanism in collisions, thus enhancing safety performance.

[0067] Secondly, the frame structure 1 is located in the middle of the vehicle body, and is connected to the door sill beams 3 on both sides. The frame longitudinal beam 103 is connected to the rear section 51 of the front engine compartment longitudinal beam, and the frame longitudinal beam 103 is connected to the lower cross beam 6, forming a multi-layer frame structure for the vehicle body force transmission path. This multi-layer frame structure can significantly improve the rigidity of the middle of the vehicle body.

[0068] In addition, as a further optimization of the vehicle body structure, refer to Figure 2 and Figure 5 As shown, seat mounting brackets 9 are provided above the front floor panel 2, corresponding to at least a portion of the lower crossbeam 6, and the seat mounting brackets 9 are connected to the front floor panel 2. Providing seat mounting brackets 9 above the front floor panel 2, corresponding to the lower crossbeam 6, offers a more stable seat mounting point. This satisfies the vehicle's seat installation needs while eliminating the need for a separate seat crossbeam above the front floor panel 2, contributing to weight reduction and cost savings. It also facilitates the arrangement of wiring harnesses and air conditioning ducts within the vehicle cabin. Generally, there are two lower crossbeams 6, and multiple seat mounting brackets 9 can be provided corresponding to each lower crossbeam 6, with the multiple seat mounting brackets 9 spaced apart in the left-right direction of the vehicle to accommodate the installation of the left and right front seats.

[0069] In this embodiment, each of the two front seats has four seat mounting brackets 9, for a total of eight seat mounting brackets 9. Two seat mounting brackets 9 are provided at the front and two at the rear of the same seat. Two lower crossbeams 6 are provided below the front floor panel 2, and these two lower crossbeams 6 are parallel to each other. The four seat mounting brackets 9 of the two front seats are connected to the front lower crossbeams 6, and the four seat mounting brackets 9 of the two rear seats are connected to the rear lower crossbeams 6.

[0070] The vehicle body structure of the embodiment can not only effectively associate the front subframe 4 and the battery pack 8 together in structure, but also provide a continuous force transmission channel between the front subframe 4 and the battery pack 8, so that the collision force can be effectively transmitted along the front subframe 4 and the battery pack 8, and the rigidity of the vehicle body structure can be improved by connecting the front subframe 4 and the battery pack 8 frame together, thereby improving the safety performance of the vehicle.

[0071] Embodiment two

[0072] Another purpose of the utility model lies in providing a vehicle, which is provided with the vehicle body structure in embodiment one.

[0073] The vehicle of the embodiment can effectively associate the front subframe and the battery pack together by arranging the frame structure, and is provided with the underlay cross beam connecting the left and right rocker beams, so that the vehicle body rigidity is higher, and the collision force can be transmitted along the front subframe to the frame structure, and then to the battery pack and other structures of the vehicle body to be dissipated and decomposed, thereby improving the anti-collision ability of the vehicle, the safety performance of the vehicle, and the protection of the passengers in the vehicle when the vehicle is subjected to the collision.

[0074] The above description is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
