[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] This application provides a vehicle frame structure; please refer to [link / reference]. Figure 1 and Figure 2 .

[0042] The vehicle body frame structure includes a crossbeam 1, two longitudinal beams 2, and at least two mounting components 3. The two longitudinal beams 2 are respectively connected to opposite ends of the crossbeam 1. The two mounting components 3 are respectively located on the longitudinal beams 2.

[0043] The crossbeam 1, the two longitudinal beams 2, and at least two mounting components 3 together form a closed-loop force transmission structure.

[0044] The crossbeam 1 can be made of high-strength steel plate and connected to the longitudinal beam 2 by welding, riveting, or bolting to ensure the strength and durability of the connection. Alternatively, the crossbeam 1 and longitudinal beam 2 can be integrally molded during manufacturing. In the closed-loop force transmission path, the longitudinal beam 2 not only works with the crossbeam 1 and mounting assembly 3 to form a closed-loop force transmission path, but also extends the force transmission path to the entire frame, thereby dispersing external forces on the vehicle body. The mounting assembly 3 is located on the longitudinal beam 2 and is used to install the first seat belt, also serving a reinforcing role in the force transmission path. When the vehicle is subjected to external forces (such as collision forces or dynamic loads), the force is transmitted along the crossbeam 1, longitudinal beam 2, and mounting assembly 3, forming a circular path. This effectively avoids single-point force concentration or path interruption, improving overall rigidity and impact resistance.

[0045] The technical solution provided in this application forms a closed-loop force transmission structure through a crossbeam 1, two longitudinal beams 2, and at least two mounting components 3. In this embodiment, there are two mounting components 3. In other embodiments, the number of mounting components 3 can be three, four, etc., depending on the actual situation, and is not limited. The closed-loop force transmission structure enables the vehicle frame to form a continuous force path during load transmission. The closed-loop structure avoids the accumulation of force at the interruption point of transmission, which helps to improve the overall rigidity of the vehicle frame. The increased rigidity can reduce the deformation of the vehicle body under dynamic loads, thereby improving the vehicle's handling and stability.

[0046] In some embodiments, the mounting assembly 3 includes a first mounting member 31 and a support member 32. The first mounting member 31 is used to mount a first seat belt. Vehicles typically have multiple seat belts, such as a driver's seat belt, a front passenger seat belt, a left rear seat belt, a right rear seat belt, and a middle rear seat belt. In this embodiment, the first seat belt can be either a left rear seat belt or a right rear seat belt. The two first mounting members 31 are used to mount the left rear seat belt and the right rear seat belt, respectively. The support member 32 is used to support the longitudinal beam 2, improving the structural strength of the longitudinal beam 2.

[0047] The support members 32 at both ends of the crossbeam 1 and the first mounting member 31 are connected to the crossbeam 1, and the support members 32 and the first mounting member 31 on the same side of the crossbeam 1 are connected through the longitudinal beam 2 to form a closed-loop force transmission structure. The first mounting member 31 provides a fixing point for the seat belt, ensuring the reliability of the seat belt installation. The first mounting member 31 not only undertakes the installation function of the first seat belt, but also participates in the formation of the force transmission path. The support member 32 is used to provide additional support for the longitudinal beam 2, and also participates in the formation of the force transmission path, improving the rigidity of the vehicle frame. One end of the support member 32 is connected to the crossbeam 1 by welding or bolting, and the other end is connected to the longitudinal beam 2, thus forming a fixed closed relationship between the crossbeam 1, the longitudinal beam 2, and the support member 32.

[0048] In some embodiments, the crossbeam 1 includes a beam body 11, a first beam edge 12, and a second beam edge 13. Along the longitudinal direction Y, the first beam edge 12 and the second beam edge 13 are respectively located on opposite sides of the beam body 11. Along the transverse direction X, the two ends of the first beam edge 12 are respectively connected to two first mounting members 31, and the two ends of the second beam edge 13 are respectively connected to two support members 32. The beam body 11 is the main structural part of the crossbeam 1, arranged along the transverse direction X, and is used to bear the transverse load of the vehicle frame. The beam body 11 can be made of high-strength steel or aluminum alloy to balance strength and lightweight objectives. The first beam edge 12 and the second beam edge 13 are respectively arranged on the longitudinal sides of the beam body 11. The two ends of the first beam edge 12 are connected to the first mounting members 31 by welding or integral forming; the two ends of the second beam edge 13 are connected to the support members 32 by welding or integral forming. The connection between the first beam edge 12 and the first mounting member 31 forms a dedicated path for the seat belt to bear the load, while the second beam edge 13 transfers the load of the longitudinal beam 2 to the main structure of the transverse beam 1 through the support member 32. The first beam edge 12, the second beam edge 13, the first mounting members 31 at both ends of the first beam edge 12, the support members 32 at both ends of the second beam edge 13, and the portion of the longitudinal beam 2 between the first mounting member 31 and the support member 32 on the same side together form a closed-loop force transmission structure.

[0049] In some embodiments, see Figure 3The first mounting component 31 includes a first mounting portion 311 for mounting the first seat belt and a plurality of first fixing portions 312. The plurality of first fixing portions 312 are disposed on the side of the first mounting portion 311. A portion of the first fixing portion 312 is fixed to the longitudinal beam 2, and another portion is fixed together with the crossbeam 1 and the longitudinal beam 2. The first mounting portion 311 is plate-shaped or bent, and its specific shape can be determined according to the structure of the longitudinal beam 2. Preferably, the first mounting portion 311 is bent, which helps to enhance the strength of the first mounting portion 311. The first fixing portions 312 are disposed on the side of the first mounting portion 311 to strengthen the connection between the first mounting component 31 and the vehicle frame. The side of the first fixing portion 312 is fixedly connected to the outer wall of the longitudinal beam 2 by spot welding or bolt connection, which can effectively bear the tensile force in the direction of the longitudinal beam 2 and ensure the rigid connection between the longitudinal beam 2 and the first mounting component 31. Another portion of the first fixing portion 312 is fixedly connected to the junction area of ​​the crossbeam 1 and the longitudinal beam 2 through a layered structure. By employing multi-layer welding or bolt fastening, the intersection points of force transmission paths are formed, further enhancing the overall connection strength. Through the coordinated design of the first mounting part 311 and multiple first fixing parts 312, the first mounting member 31 forms a multi-point fixing structure under the dual support of the longitudinal beam 2 and the transverse beam 1. Compared to a single-point fixing design, multi-point fixing can disperse the load generated when the seat belt is under stress, significantly improving the rigidity of the mounting point. The first mounting part 311 and the first fixing parts 312 form a mechanically closed-loop path. The tension of the seat belt is transmitted to the longitudinal beam 2 and the transverse beam 1 through the first mounting member 31, while the fixing parts provide additional support around the mounting point, further reducing stress concentration effects and enhancing structural stability.

[0050] Furthermore, the first fixing part 312 includes a first fixing piece 3121 and a second fixing piece 3122. The first fixing piece 3121 is connected to one side of the first mounting part 311 and fixedly connected to one side of the longitudinal beam 2. The fixing connection is achieved by spot welding, so that the first fixing piece 3121 is spot welded to one side of the longitudinal beam 2. The first fixing piece 3121 is directly connected to one side of the longitudinal beam 2, reliably transferring the longitudinal load of the first mounting part 311 to the longitudinal beam 2, avoiding interruption of force transmission in the direction of the longitudinal beam 2, and providing high-strength longitudinal support. The second fixing piece 3122 is connected to the side of the first mounting part 311 away from the first fixing piece 3121. The second fixing piece 3122, the side of the longitudinal beam 2 away from the first fixing piece 3121, and the crossbeam 1 are stacked and fixed, using a three-layer welding method, so that the second fixing piece 3122, the longitudinal beam 2, and the crossbeam 1 are welded and fixed together. The second fixing piece 3122 connects the first mounting part 311, the crossbeam 1 and the longitudinal beam 2 together by layer welding, forming a multi-point support joint area to avoid local deformation or loosening at the connection between the crossbeam 1 and the longitudinal beam 2.

[0051] In some embodiments, the first mounting portion 311 includes a mounting surface 3111, a first bent surface 3112, and a second bent surface 3113. The first bent surface 3112 and the second bent surface 3113 are respectively disposed on both sides of the mounting surface 3111, with the first bent surface 3112 forming a first crease with the mounting surface 3111, and the second bent surface 3113 forming a second crease with the mounting surface 3111. The first bent surface 3112, the second bent surface 3113, and the mounting surface 3111 together define a mounting cavity, which is mounted towards the longitudinal beam 2 to match the structure of the longitudinal beam 2. Furthermore, the first and second creases enhance the structural strength of the first mounting portion 311.

[0052] Furthermore, the mounting surface 3111 has a first positioning hole 3114 and a first mounting hole 3115. The first mounting hole 3115 is used to install the first seat belt. The first positioning hole 3114 is used to position the first seat belt to facilitate installation of the seat belt into the first mounting hole 3115.

[0053] In some embodiments, one side of the support member 32 is fixed to the side of the longitudinal beam 2 away from the crossbeam 1, and the other side is stacked and fixed to the crossbeam 1 and the longitudinal beam 2, so that the support member 32 can be firmly fixed to the longitudinal beam 2 and play a role in force transmission. One side of the support member 32 is fixed to the side of the longitudinal beam 2 away from the crossbeam 1, so that the support member 32 can bear the force transmitted from the longitudinal beam, and through the stacking and fixing of the support member 32 to the crossbeam 1 and the longitudinal beam 2, the force is transmitted to the crossbeam 1, forming a closed-loop force transmission.

[0054] Further, please see Figure 4 The support member 32 includes a peripheral surface 321 and a top surface 322. The peripheral surface 321 is connected to the circumferential edge of the top surface 322 and forms a cavity 323, allowing the support member 32 to adapt to the installation structure of the longitudinal beam 2. Because the peripheral surface 321 and the top surface 322 form a cavity 323, the connection between the two surfaces enhances structural strength. The top surface 322 is recessed towards the cavity 323 to form reinforcing ribs 324 within the cavity 323, further improving the structural strength of the support member 32.

[0055] In some embodiments, the vehicle frame structure further includes a shock absorber mounting base 21 for mounting shock absorbers. The shock absorber mounting base 21 is connected to the side of the support member 32 away from the crossbeam 1. The shock absorber mounting base 21, the support member 32, and the longitudinal beam 2 are stacked and fixedly connected. The fixed connection can be achieved by multi-layer welding, i.e., the shock absorber mounting base 21, the support member 32, and the longitudinal beam 2 are stacked and welded in three layers. Connecting the support member 32 to the shock absorber mounting base 21 allows the force borne by the support member 32 to be distributed to the shock absorber mounting base 21, which helps to increase the maximum force that the vehicle frame structure can withstand.

[0056] In some embodiments, see Figure 5 The vehicle frame structure also includes at least one second mounting member 4 for mounting the seat frame. The second mounting member 4 is disposed on the crossbeam 1. The second mounting member 4, disposed on the crossbeam 1, can improve the load-bearing capacity of the crossbeam 1, and can also distribute some of the load to the seat frame, further improving the load-bearing capacity of the crossbeam 1. In this embodiment, there are two second mounting members 4, which are distributed at intervals along the lateral direction X on the crossbeam 1, making the load on the crossbeam 1 more even.

[0057] Furthermore, the second mounting component 4 includes a second mounting portion 41 and a second fixing portion 42. The second mounting portion 41 is used to mount the seat frame. The second mounting portion 41 covers the crossbeam 1 along the longitudinal direction Y, enabling the second mounting portion 41 to distribute force to the seat frame and improve the load-bearing capacity of the crossbeam 1 in the longitudinal direction Y. The second fixing portion 42 is located at the circumferential edge of the second mounting portion 41 and is fixedly connected to the beam 11, the first beam edge 12, and the second beam edge 13. A multi-point fixing method is used to ensure that the second fixing portion 42 is stably fixed to the crossbeam 1. Furthermore, by fixing the second fixing portion 42 to the beam 11, the first beam edge 12, and the second beam edge 13, the second fixing portion 42 can transmit force to the beam 11, the first beam edge 12, and the second beam edge 13, improving the uniformity of force distribution.

[0058] Furthermore, the second mounting portion 41 is provided with a seat frame mounting hole 411, a seat frame main positioning hole 412, and a seat frame secondary positioning hole 413. The seat frame mounting hole 411 is used to connect the seat frame, and the seat frame main positioning hole 412 and seat frame secondary positioning hole 413 are used to assist the seat frame in being installed into the seat frame mounting hole 411, facilitating the installation of the seat frame. The second mounting portion 41 is U-shaped, giving it a certain bending structure and improving its own strength.

[0059] In some embodiments, see Figure 1 and Figure 6 The vehicle frame structure also includes a third mounting member 5. The third mounting member 5 is mounted on the crossbeam 1 and is used to install the second seatbelt. This allows the third mounting member 5 to enhance the structural strength of the crossbeam 1 while also transferring some of the force to the second seatbelt, further distributing the load and improving the load-bearing capacity of the crossbeam 1. The second seatbelt is a middle or rear seatbelt; however, in other embodiments, it can be any other seatbelt. Along the lateral direction X, the third mounting member 5 is positioned between the two second mounting members 4 to accommodate the installation positions of the first and second seatbelts.

[0060] Further, please see Figure 6The third mounting component 5 includes a third mounting part 51 and a third fixing part 52. The third mounting part 51 is used to mount the second safety belt. The third mounting part 51 covers the crossbeam 1 in the longitudinal direction Y, so that the third mounting part 51 can bear as much of the force on the crossbeam 1 in the longitudinal direction Y as possible. The third fixing part 52 is located at the circumferential edge of the third mounting part 51. The third fixing part 52 is fixedly connected to the beam 11, the first beam edge 12, and the second beam edge 13. The fixing connection can be welding or threaded connection, etc. By fixing the third fixing part 52 to the beam 11, the first beam edge 12, and the second beam edge 13, the third fixing part 52 can bear the force from the beam 11, the first beam edge 12, and the second beam edge 13, and then transfer the force it bears to the third mounting part 51, and then to the fixing device related to the safety belt through the third mounting part 51, which helps to improve the load-bearing capacity of the crossbeam 1.

[0061] Furthermore, the third mounting section 51 is provided with a main seat belt positioning hole 511, a secondary seat belt positioning hole 512, multiple seat back mounting holes 513, and a seat belt mounting hole 514. The seat belt is installed using the main seat belt positioning hole 511, the secondary seat belt positioning hole 512, and the seat belt mounting hole 514. The multiple seat back mounting holes 513 are used to install the seat back, allowing the force on the third mounting section 51 to be transmitted to the seat back, thus distributing the force on the crossbeam 1 more evenly. The number of seat back mounting holes 513 is determined according to the installation requirements of the seat back; for example, in this embodiment, there are three seat back mounting holes 513.

[0062] In some embodiments, the crossbeam 1 is provided with a fourth mounting member 6 for mounting a child seat. Specifically, the fourth mounting member 6 is located between the two first mounting members 31 and the second mounting member 4, allowing the child seat to be installed between the two seats for easy monitoring of the child. Furthermore, the fourth mounting member 6 can also distribute the force on the crossbeam 1 to the child seat, thereby improving the load-bearing capacity of the crossbeam 1.

[0063] In some embodiments, the crossbeam 1 further includes two connecting portions 14. The two connecting portions 14 are respectively disposed at both ends of the beam body 11 in the transverse direction X. The connecting portions 14 are connected to the first beam edge 12 and the second beam edge 13 on both sides in the longitudinal direction Y, respectively. The side of the connecting portion 14 away from the first beam edge 12 and the second beam edge 13 is connected to the first mounting member 31 and the support member 32, so that force can be transmitted between the first beam edge 12 and the first mounting member 31, and between the second beam edge 13 and the support member 32.
