[0031] With the continuous development and popularization of automobiles, people have increasingly higher requirements for vehicle collision safety, driving range, and ride comfort. The vehicle body frame is a key structure of an automobile, playing a role in bearing and distributing loads, and ensuring driving stability and safety. Among them, the collision force transmission structure formed by the connection between the side beams and A-pillars is one of the force transmission structures of the vehicle body frame, and this collision force transmission structure plays a crucial role in the safety of the passenger compartment. However, in existing technologies, the force transmission performance of this part of the vehicle body frame's collision force transmission structure is poor, resulting in poor collision performance.

[0032] To address the related technical problems, this application provides a vehicle that includes the following front body frame.

[0033] To address the related technical issues, this application also provides a front vehicle body frame, for details please refer to [link / reference needed]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a structural embodiment of the front body frame provided in this application. Figure 2 yes Figure 1 A schematic diagram of one embodiment of the cabin side beam assembly and A-pillar assembly is shown.

[0034] The front body frame 10 includes a cabin side beam assembly 100 and an A-pillar assembly 200. The cabin side beam assembly 100 extends in a first direction X. The A-pillar assembly 200 includes an A-pillar body 210 and a force transmission part 220. The A-pillar body 210 connects to the cabin side beam assembly 100 in the first direction X, and the force transmission part 220 connects the cabin side beam assembly 100 and the A-pillar body 210 in a second direction Z intersecting the first direction X. The force transmission part 220 includes a first force transmission beam 2. 21 and the second force transmission beam 222, one end of the first force transmission beam 221 is connected to the A-pillar body 210, and one end of the second force transmission beam 222 is connected to the cabin side beam assembly 100. The connection between the first force transmission beam 221 and the A-pillar body 210 and the connection between the second force transmission beam 222 and the cabin side beam assembly 100 are spaced apart in the first direction X. The end of the first force transmission beam 221 away from the A-pillar body 210 and the end of the second force transmission beam 222 away from the cabin side beam assembly 100 are connected to each other.

[0035] The front body frame 10 can be understood as the frame of the front of the vehicle. The vehicle also includes a middle body frame. The front body frame 10 is connected to the middle body frame so that the front body frame 10 can transfer the collision force to the middle body frame. The front body frame 10 includes the engine compartment side beam assembly 100 and the A-pillar assembly 200.

[0036] The engine compartment side beam assembly 100 extends in a first direction X, which can be understood as the vehicle's longitudinal direction. The engine compartment side beam assembly 100 can be connected to the central body frame via the A-pillar assembly 200. When the vehicle is subjected to a collision from the first direction X, the engine compartment side beam assembly 100 can transmit the collision force in the first direction X, thereby timely transmitting the collision force to the vehicle body and reducing the risk of the collision force intruding into the passenger compartment.

[0037] The A-pillar assembly 200 comprises an A-pillar main body 210 and a force transmission part 220. The A-pillar main body 210 is arranged to extend in the second direction Z, which can be understood as the height direction of the vehicle. The A-pillar main body 210 is connected to the cabin side rail assembly 100 in the first direction X, so that the cabin side rail assembly 100 transmits the collision force to the A-pillar main body 210 in the first direction X. The force transmission part 220 connects the cabin side rail assembly 100 and the A-pillar main body 210 in the second direction Z, and the cabin side rail assembly 100 and the A-pillar main body 210 are adjacently arranged in the first direction X, such that the cabin side rail assembly 100, the A-pillar main body 210 and the force transmission part 220 are arranged in a "pin-shaped" layout, which can improve the connection stability among the cabin side rail assembly 100, the A-pillar main body 210 and the force transmission part 220. The central body frame can comprise an upper longitudinal rail, which is arranged to extend in the first direction X. The upper longitudinal rail is a longitudinal rail at the upper part of the vehicle door, one end of the upper longitudinal rail away from the A-pillar assembly 200 is connected to the C-pillar, and one end of the force transmission part 220 away from the A-pillar main body 210 is connected to the upper longitudinal rail, so that the collision force from the cabin side rail assembly 100 can be transmitted to the upper longitudinal rail through the force transmission part 220, thereby allowing the collision force to be transmitted to the entire vehicle body.

[0038] The force transmission part 220 comprises a first force transmission beam 221 and a second force transmission beam 222. One end of the first force transmission beam 221 in the second direction Z is connected to the A-pillar main body 210, and one end of the second force transmission beam 222 in the second direction Z is connected to the cabin side rail assembly 100. The ends of the first force transmission beam 221 and the second force transmission beam 222 away from the A-pillar main body 210 are connected to each other, and the mutually connected ends of the first force transmission beam 221 and the second force transmission beam 222 are jointly connected to the upper longitudinal rail. This enables the A-pillar assembly 200 to have a first force transmission path and a second force transmission path, wherein the first force transmission path is the cabin side rail assembly 100, the second force transmission beam 222 to the upper longitudinal rail, and the second force transmission path is the cabin side rail assembly 100, the A-pillar main body 210, the first force transmission beam 221 to the upper longitudinal rail.

[0039] With the above embodiment, one ends of the first force transmission beam 221 and the second force transmission beam 222 of the force transmission part 220 are connected to each other, and the ends of the first force transmission beam 221 and the second force transmission beam 222 away from the mutually connected end are respectively connected to the A-pillar main body 210 and the cabin side rail assembly 100, so that the force transmission path between the cabin side rail assembly 100 and the A-pillar assembly 200 can be divided into two paths: one is from the cabin side rail assembly 100 to the first force transmission beam 221, and the other is from the cabin side rail assembly 100 and the A-pillar main body 210 to the second force transmission beam 222. The force transmission performance of the front body frame 10 can be improved, and the crash performance of the front body frame 10 can be enhanced.

[0040] In some embodiments, the number of both the cabin side beam assembly 100 and the A-pillar assembly 200 may be two. The front body frame 10 also includes a front bulkhead assembly. The two cabin side beam assemblies 100 are spaced apart in a third direction Y, and the two A-pillar assemblies 200 are also spaced apart in a third direction Y, which can be understood as the width direction of the vehicle. Each cabin side beam assembly 100 is paired with a corresponding A-pillar assembly 200, and the two sets of cabin side beam assemblies 100 and A-pillar assemblies 200 are respectively connected to both ends of the front bulkhead assembly in the third direction Y. This improves the force transmission performance of the front body frame 10 and enhances its collision performance.

[0041] In some embodiments, the A-pillar assembly 200 includes an inner A-pillar panel 230 and an outer A-pillar panel 240, which are connected to each other so that a first force transmission beam 221 forms a first force transmission cavity and a second force transmission beam 222 forms a second force transmission cavity.

[0042] The A-pillar assembly 200 includes an inner A-pillar panel 230 and an outer A-pillar panel 240, which are interconnected in the third direction Y. This allows the first force-transmitting beam 221 and the second force-transmitting beam 222 of the A-pillar assembly 200 to each form a cavity. The first force-transmitting beam 221 has a first force-transmitting cavity inside, which extends along its length. The second force-transmitting beam 222 has a second force-transmitting beam inside, which also extends along its length. The ends of the first and second force-transmitting cavities away from the A-pillar body 210 are interconnected. This improves the structural strength of the first and second force-transmitting beams 221 and 222.

[0043] In this embodiment, the A-pillar inner panel 230 may include a force-transmitting inner panel 231 and a main body inner panel 232, and the A-pillar outer panel 240 may include a force-transmitting outer panel 241 and a main body outer panel 242. The main body inner panel 232 and the main body outer panel 242 are interconnected to form a second energy-absorbing cavity to improve the structural strength of the A-pillar body 210. The first force-transmitting cavity and the second force-transmitting cavity are formed by the force-transmitting inner panel 231 and the force-transmitting outer panel 241. Of course, in some other embodiments, the force-transmitting outer panel 241 and the main body outer panel 242 may also be integrally formed to form the A-pillar outer panel 240.

[0044] In some embodiments, the angle between the first force transmission beam 221 and the cabin side beam assembly 100 is smaller than the angle between the second force transmission beam 222 and the A-pillar body 210.

[0045] The angle between the second force transmission beam 222 and the engine compartment side beam assembly 100 is angle α, and the angle between the first force transmission beam 221 and the A-pillar body 210 is angle β. Angle α is smaller than angle β, so that the force transmission part 220 is tilted away from the engine compartment side beam assembly 100 in the first direction X. This facilitates the transmission of collision forces from the engine compartment side beam assembly 100 to the central body frame.

[0046] See Figure 3 and Figure 4 , Figure 3 yes Figure 2 The diagram shows the disassembly of the cabin side beam assembly and the A-pillar assembly. Figure 4 yes Figure 2 The diagram shows the structure of the cabin side beam assembly and A-pillar assembly after removing the outer panel of the side beam.

[0047] In some embodiments, the cabin side beam assembly 100 includes an inner side beam plate 110 and an outer side beam plate 120. The inner side beam plate 110 is connected to the inner A-pillar plate 230 in a first direction X and a second direction Z. The outer side beam plate 120 is connected to one side of the inner side beam plate 110 and the inner A-pillar plate 230 to form a first energy-absorbing cavity. A portion of the outer A-pillar plate 240 is located in the first energy-absorbing cavity and is connected to the inner side beam plate 110, the outer side beam plate 120, and the inner A-pillar plate 230.

[0048] The inner plate 110 of the side beam is connected to the inner plate 230 of the A-pillar in the first direction X and the second direction Z. Specifically, the inner plate 232 of the main body and the inner plate 110 of the side beam are arranged adjacently and connected in the first direction X. The size of the force-transmitting inner plate 231 can be larger than the size of the force-transmitting outer plate 241 so that the force-transmitting inner plate 231 can be connected to the inner plate 232 of the main body and the inner plate 110 of the side beam in the second direction Z. The outer plate 120 of the side beam is connected to the same side of the inner plate 110 of the side beam and the inner plate 230 of the A-pillar so that the outer plate 120 of the side beam, the inner plate 110 of the side beam and part of the inner plate 230 of the A-pillar together form the first energy-absorbing cavity. A portion of the A-pillar outer panel 240 is located within the first energy-absorbing cavity. One side of the A-pillar outer panel 240 connects to the side beam inner panel 110, the force-transmitting inner panel 231, and the main body inner panel 232 near the side beam outer panel 120. The side of the side beam outer panel 120 near the side beam inner panel 110 connects to the force-transmitting outer panel 241 and the main body outer panel 242 away from the A-pillar inner panel 230. The side of the side beam outer panel 120 connected to the force-transmitting outer panel 241 also connects to the side beam inner panel 110 and the force-transmitting inner panel 231. Thus, a portion of the A-pillar outer panel 240 is sandwiched and connected between the side beam inner panel 110, the force-transmitting inner panel 231, and the side beam outer panel 120, improving the connection strength between the cabin side beam assembly 100 and the A-pillar assembly 200, thereby improving the stability of force transmission between the cabin side beam assembly 100 and the A-pillar assembly 200.

[0049] In some embodiments, the cabin side beam assembly 100 forms a first energy-absorbing cavity, and the A-pillar assembly 200 forms a second energy-absorbing cavity. The outer A-pillar panel 240 is further provided with connecting side plates on both sides in the first direction X. The portion of the outer A-pillar panel 240 located between the two connecting side plates is spaced apart from the main body inner panel 232. The connecting side plate near the cabin side beam assembly 100 is connected to the force-transmitting inner panel 231, the side beam inner panel 110, and the main body inner panel 232, while the connecting side plate away from the cabin side beam assembly 100 is connected to the force-transmitting inner panel 231 and the main body inner panel 232. The connecting side plate has a certain inclination angle with the force-transmitting inner panel 231, the side beam inner panel 110, and the main body inner panel 232, thereby separating the first and second energy-absorbing cavities by the connecting side plates. This improves the structural strength of the cabin side beam assembly 100 and the A-pillar assembly 200.

[0050] In some embodiments, the force transmission part 220 includes a connecting part 223, one end of which is connected to the ends of the first force transmission beam 221 and the second force transmission beam 222 spaced apart from each other in the second direction Z, and the portion of the connecting part 223 away from the end of the second force transmission beam 222 in the second direction Z is connected to the A-pillar body 210.

[0051] The force transmission section 220 includes a connecting section 223. One end of the connecting section 223 in the second direction Z is connected to the first force transmission beam 221 and the second force transmission beam 222. The connections between the first force transmission beam 221, the second force transmission beam 222, and the connecting section 223 are spaced apart in the first direction X. The end of the connecting section 223 in the second direction Z away from the second force transmission beam 222 is connected to the A-pillar body 210. Thus, the first force transmission beam 221, the second force transmission beam 222, and the connecting section 223 form a stable triangular structure, which can improve the structural strength of the force transmission section 220.

[0052] In some embodiments, the remaining portion of the connecting portion 223, located away from one end of the second force transmission beam 222 in the second direction Z, is connected to the cabin side beam assembly 100.

[0053] Therefore, one end of the connecting portion 223 in the second direction Z connects to the first force transmission beam 221 and the second force transmission beam 222, and the other end of the connecting portion 223 in the second direction Z is used to connect the engine compartment side beam assembly 100 and the A-pillar assembly 200. This increases the connection area between the engine compartment side beam assembly 100 and the force transmission portion 220 in the second direction Z. When the vehicle is subjected to a side impact force, causing the engine compartment side beam assembly 100 to be subjected to a rollover impact force around the first direction X, the second direction Z, or the third direction Y, the two ends of the connecting portion 223 in the second direction Z connect the first force transmission beam 221, the second force transmission beam 222, the engine compartment side beam assembly 100, and the A-pillar body 210. This improves the ability of the engine compartment side beam assembly 100 to resist rollover impact forces and enhances the collision performance of the front body frame 10.

[0054] In some embodiments, the front body frame 10 further includes a windshield crossbeam 300 and a shock absorber tower 400, which are arranged opposite to each other and spaced apart in the second direction Z. The windshield crossbeam 300 extends in the first direction X, and the shock absorber tower 400 is connected to the engine compartment side beam assembly 100 in the second direction Z. One end of the windshield crossbeam 300 is connected to the side of the connecting portion 223 away from the A-pillar outer panel 240.

[0055] The front body frame 10 includes a windshield crossbeam 300 and a shock absorber tower 400. The shock absorber tower 400 is connected to the engine compartment side beam assembly 100 in the second direction Z. The engine compartment side beam assembly 100 is connected to the connecting part 223 in the second direction Z. The windshield crossbeam 300 extends in the third direction Y. The windshield crossbeam 300 is opposite to and spaced apart from the shock absorber tower 400 in the second direction Z. One end of the windshield crossbeam 300 in the third direction Y is connected to the side of the connecting part 223 away from the outer panel. Therefore, the connection between the windshield beam 300 and the connecting part 223 and the connection between the shock absorber tower 400 and the engine compartment side beam assembly 100 are spaced apart in the second direction Z. The engine compartment side beam assembly 100 is also connected to the A-pillar body 210 in the first direction X. The connection between the engine compartment side beam assembly 100 and the A-pillar body 210 and the connection between the connecting part 223 and the windshield beam 300 are spaced apart in the first direction X. This can further improve the ability of the engine compartment side beam assembly 100 and the A-pillar assembly 200 to resist the collision force of rollover and improve the collision performance of the front body frame 10.

[0056] See Figure 5 , Figure 5 yes Figure 3 A schematic diagram of one embodiment of the inner plate of the side beam is shown.

[0057] In some embodiments, the inner plate 110 of the side beam includes an inner plate body 111 and an inner plate connecting plate 112. One end of the inner plate body 111 is connected to the outer plate 120 of the side beam through the inner plate connecting plate 112. At least a portion of the inner plate connecting plate 112 near the A-column outer plate 240 is perpendicular to the inner plate body 111 and the outer plate 120 of the side beam, and is connected to the A-column outer plate 240.

[0058] The inner plate 110 of the side beam includes an inner plate body 111 and an inner plate connecting plate 112. The inner plate connecting plate 112 can be connected to one end of the inner plate body 111 in the second direction Z away from the force-transmitting inner plate 231. One end of the outer plate 120 of the side beam is connected to the end of the inner plate connecting plate 112 away from the inner plate body 111. Specifically, one end of the inner plate connecting plate 112 in the first direction X is connected to the outer plate 240 of the A-column, and the portion of the inner plate connecting plate 112 connected to the outer plate 240 of the A-column is perpendicular to the inner plate body 111 and the outer plate 120 of the side beam. For example, a support plate 1123 is provided at one end of the inner plate connecting plate 112 near the outer plate 240 of the A-column. The support plate 1123 is perpendicular to and connected to the inner plate body 111 and the outer plate 120 of the side beam, and one end of the support plate 1123 is connected to the outer plate 240 of the A-column, so that the support plate 1123 has a certain length in the third direction Y. The support plate 1123 has three connecting flanges, which are respectively connected to the inner panel body 111, the side beam outer plate 120, and the A-pillar outer plate 240 to increase the connection area and make the connection more stable. Thus, the portion of the inner panel connecting plate 112 connected to the A-pillar outer plate 240 is perpendicular to both the inner panel body 111 and the side beam outer plate 120, and is also positioned in the third direction Y, connecting to the A-pillar outer plate 240. When subjected to a rotational collision force about the first direction X (which can be understood as the vehicle being subjected to a collision force in the third direction Y), the ability of the engine compartment side beam assembly 100 to resist rotational collision forces can be improved, thus improving the collision performance of the front body frame 10. The separate arrangement of the support plate 1123 and the inner panel connecting plate 112 allows the support plate 1123 to have a good fixing effect with the A-pillar outer plate 240. Of course, in some other embodiments, the support plate 1123 can also be integrally arranged with the inner panel connecting plate 112.

[0059] In some embodiments, the front body frame 10 includes a shock absorber tower 400, and the inner panel connecting plate 112 includes a first connecting plate 1121 and a second connecting plate 1122. The first connecting plate 1121 is connected to the inner panel body 111 and the second connecting plate 1122 respectively. The end of the second connecting plate 1122 away from the first connecting plate 1121 is connected to the outer plate of the side beam 120. The second connecting plate 1122 is perpendicular to the outer plate of the side beam 120. The first connecting plate 1121 and the second connecting plate 1122 are inclined. The shock absorber tower 400 is connected to the first connecting plate 1121 and the second connecting plate 1122 in the second direction Z.

[0060] The first connecting plate 1121 is connected to the second connecting plate 1122 and the inner plate body 111 at both ends. The end of the second connecting plate 1122 away from the first connecting plate 1121 is connected to the outer plate 120 of the side beam. The second connecting plate 1122 can be set perpendicular to the outer plate 120 of the side beam. The first connecting plate 1121 and the second connecting plate 1122 have a certain tilt angle, thus connecting the second connecting plate 1122 and the inner plate body 111 at an angle. The damping tower 400 is connected to the first connecting plate 1121 and the second connecting plate 1122 in the second direction Z. Thus, the second connecting plate 1122 is set vertically and the first connecting plate 1121 is set at an angle, which can improve the structural strength of the cabin side beam assembly 100. The connection between the damping tower 400 and the first connecting plate 1121 and the second connecting plate 1122 in the second direction Z can increase the connection area between the damping tower 400 and the cabin side beam assembly 100. It can also effectively improve the force transmission effect between the shock absorber tower 400 and the cabin side beam assembly 100 when subjected to collision forces from different directions.

[0061] In summary, the force transmission path between the cabin side beam assembly 100 and the A-pillar assembly 200 can be divided into two paths: one is from the cabin side beam assembly 100 to the first force transmission beam 221, and the other is from the cabin side beam assembly 100 and the A-pillar body 210 to the second force transmission beam 222. This improves the force transmission performance of the front body frame 10 and enhances its collision performance.
