[0035] As people's demand for vehicles increases, the requirements for the overall driving and riding experience of electric vehicles are becoming increasingly higher, with driving comfort and collision safety performance receiving significant attention and emphasis. The engine compartment houses many critical components, such as longitudinal beams, shock absorber towers, and crossbeams. In existing technologies, the connection strength and stability between these critical components are relatively poor, resulting in poor vehicle collision performance.

[0036] To address the related technical problems, this application provides a vehicle that includes a front frame connected to the vehicle body, which can improve the vehicle's collision performance.

[0037] To address the related technical problems, this application also provides a front frame, for details please refer to [link / reference needed].

Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the shock-absorbing tower.

[0038] The front frame 10 includes a front longitudinal beam 100, a lower crossbeam 200, a shock absorber tower 300, and a first fixing member 400. The front longitudinal beam 100 extends along the longitudinal direction X. The lower crossbeam 200 includes a crossbeam body 210 and a connector 220. The crossbeam body 210 extends along the transverse direction Y. The connector 220 is connected to one side of the crossbeam body 210 in the longitudinal direction X. The transverse direction Y and the longitudinal direction X intersect. The shock absorber tower 300 includes a first connecting part 310 and a second connecting part 320 arranged sequentially along the longitudinal direction X. The first connecting part 310 is connected to the front longitudinal beam 100, and the second connecting part 320 corresponds to the connector 220. The first fixing member 400 extends along the transverse direction Y and passes through the front longitudinal beam 100, the connector 220, and the second connecting part 320 to fix the front longitudinal beam 100, the connector 220, and the second connecting part 320.

[0039] The front longitudinal beam 100 is positioned along the longitudinal direction X to bear the impact force in this direction, reducing the risk of the impact force directly penetrating the passenger compartment. The longitudinal direction X can be understood as the width direction of the lower crossbeam 200, i.e., the vehicle's longitudinal direction. One end of the front longitudinal beam 100 can be connected to an energy-absorbing box and a crash beam. The energy-absorbing box is connected to the end of the front longitudinal beam 100, and the crash beam is connected to the front longitudinal beam 100 via the energy-absorbing box. The front longitudinal beam 100 provides a robust mounting base for the energy-absorbing box and the crash beam, ensuring the crash beam functions effectively in low-speed collisions or everyday driving. In the event of a frontal or small-angle offset collision, the impact force first acts on the crash beam, then is transferred to the energy-absorbing box. The energy-absorbing box has pre-set crush-inducing grooves, efficiently absorbing and dissipating a large amount of impact kinetic energy. After initial buffering and absorption by the energy-absorbing box, the remaining impact energy is transferred rearward through the front longitudinal beam 100 itself. The front longitudinal beam 100 may include a crush-inducing structure, which may include corrugations, grooves, and reinforcing structures of different strengths or thicknesses, to continue to undergo orderly crush deformation during the transmission of impact force, further absorbing energy.

[0040] The lower crossbeam 200 includes a crossbeam body 210 and a connector 220. The crossbeam body 210 extends in the lateral direction Y, which can be understood as the length direction of the lower crossbeam 200. The connector 220 is connected to one side of the crossbeam body 210, specifically the side closer to the front of the vehicle. The front longitudinal beam 100 is connected to the crossbeam body 210 through the connector 220. The crossbeam body 210 may include a main body and two side parts. The main body extends in the lateral direction Y, and the two side parts are respectively connected to both ends of the main body in the lateral direction. The two side parts are symmetrically arranged with reference to the main body. The end of the side part away from the main body extends obliquely towards the rear of the vehicle in the longitudinal direction X, so that the lower crossbeam 200 can better transmit the impact force to the rear through the side parts. The connector 220 can be located at the connection between the side and the main body, and the front longitudinal beam 100 is connected to the connector 220, so that the front longitudinal beam 100 can transmit the impact force to the main body and the side through the connector 220 at the same time, so that the impact force can be more effectively transmitted to the rear of the vehicle through the side.

[0041] The damping tower 300 has a first connecting portion 310 and a second connecting portion 320 sequentially arranged in the longitudinal direction X. The first connecting portion 310 is further away from the lower crossbeam 200 than the second connecting portion 320. The first connecting portion 310 is connected to the front longitudinal beam 100, and the second connecting portion 320 corresponds to the connector 220. The second connecting portion 320, the front longitudinal beam 100, and the connector 220 are fixed by a first fixing member 400 extending in the transverse direction Y. That is, the front longitudinal beam 100 and the second connecting portion 320 of the damping tower 300 are both positioned opposite to the connector 220, and are fixed by the first fixing member 400 simultaneously passing through the connector 220, the front longitudinal beam 100, and the second connecting portion 320. The damping tower 300 also includes a damping frame column, which forms a column-shaped structural cavity to improve the structural strength of the damping tower 300. A mounting base is provided at the end of the shock absorber frame column away from the front longitudinal beam 100. The mounting base provides an installation point for the shock absorber to connect with and absorb vehicle vibrations. A reinforcing rib network may be provided on the mounting base to improve the structural strength of the shock absorber tower 300. A first connecting part 310 may be connected to the end of the shock absorber frame column near the front longitudinal beam 100. There may be two first connecting parts 310, which are spaced apart. The gap between the two first connecting parts 310 may extend to the shock absorber frame column, thereby forming a collapse area between the two first connecting parts 310 and improving the shock absorber tower 300's ability to absorb impact forces.

[0042] For example, the first fastener 400 may include a connecting bolt and a press-fit sleeve connecting bolt. The press-fit sleeve may include a main body, a snap-fit ​​portion, and an insert portion arranged sequentially in the transverse direction Y. The main body, snap-fit ​​portion, and insert portion are provided with communicating internal threads, and the connecting bolt is fixed to the press-fit sleeve through the internal threads. The outer periphery of the snap-fit ​​portion is provided with a plurality of anti-rotation teeth, which are spaced apart circumferentially along the snap-fit ​​portion. The radial dimension of the insert portion is smaller than the radial dimension of the snap-fit ​​portion, and it cooperates with the snap-fit ​​portion to form a guide groove. The groove depth of the guide groove from the end away from the snap-fit ​​portion to the end near the snap-fit ​​portion can be progressively reduced. Taking the connecting bolt sequentially passing through the front longitudinal beam 100, the connecting head 220, and the second connecting portion 320 as an example, the press-fit sleeve is provided at the other end of the connecting bolt to fix the front longitudinal beam 100, the connecting head 220, and the second connecting portion 320 between the connecting bolt and the press-fit sleeve. The second connecting part 320 has a mounting hole at the position corresponding to the press-fit sleeve. The radial dimension of the mounting hole is smaller than that of the snap-fit ​​part, so that the plate around the mounting hole is pressed into the guide groove and between the intervals of the multiple anti-rotation teeth, thereby fixing the press-fit sleeve to the second connecting part 320 and improving the stability of the first fastener 400. There can be multiple first fasteners 400, which are spaced apart, and all of the multiple first fasteners 400 pass through and fix the connector 220, the front longitudinal beam 100 and the second connecting part 320.

[0043] Through the above implementation method, the shock absorber tower 300 is provided with a first connecting part 310 and a second connecting part 320 in sequence along the longitudinal direction X. The first connecting part 310 is connected to the front longitudinal beam 100, and the second connecting part 320 is fixedly connected to the connector 220 of the front longitudinal beam 100 and the lower cross beam 200 through the first fixing member 400, thereby improving the connection strength and stability between the front longitudinal beam 100, the lower cross beam 200 and the shock absorber tower 300, and improving the collision performance of the vehicle.

[0044] See Figures 5 to 7 , Figure 5 yes Figure 1 The diagram shows a partial disassembly of the front frame. Figure 6 yes Figure 5 An enlarged structural diagram at point D (dashed box). Figure 7 yes Figure 4 An enlarged structural diagram at point C (dashed box).

[0045] In some embodiments, the connector 220 includes a connecting body 221 extending in the longitudinal direction X. The connecting body 221 includes a main plate 2211, bent side plates 2212, and connecting side plates 2213. One end of each of the two bent side plates 2212 is connected in the transverse direction Y to both ends of the main plate 2211 in the vertical direction Z. The two connecting side plates 2213 are connected in the vertical direction Z to the other end of each bent side plate 2212, forming a mounting groove 130. The connector 220 includes a connecting body 221 extending in the longitudinal direction X. The extended portion is connected to the front longitudinal beam 100 and the second connecting portion 320, thereby increasing the connection area with the front longitudinal beam 100 and the shock absorber tower 300, and improving the connection strength and stability between the lower crossbeam 200 and the front longitudinal beam 100 and the shock absorber tower 300. Specifically, the connecting body 221 may include a main plate 2211, bent side plates 2212, and connecting side plates 2213. Two bent side plates 2212 are respectively connected to one end of the main plate 2211 in the vertical direction Z. Both bent side plates 2212 are arranged in the horizontal direction Y to form a mounting groove 130 with the main plate 2211. The vertical direction Z can be understood as the height direction of the lower crossbeam 200. Two connecting side plates 2213 are respectively connected to the side of the bent side plates 2212 away from the main plate 2211, and the connecting side plates 2213 are arranged in the vertical direction Z to connect with the front longitudinal beam 100 and the second connecting part 320. One end of the front longitudinal beam 100 is inserted into the mounting groove 130 and connected to the main plate 2211 and the connecting side plates 2213, thereby improving the strength and stability of the connection between the front longitudinal beam 100 and the connecting head 220, allowing the impact force to be transmitted more stably through the front longitudinal beam 100 to the lower crossbeam 200.

[0046] In some embodiments, the front longitudinal beam 100 includes an inner longitudinal beam plate 110 and an outer longitudinal beam plate 120. The inner longitudinal beam plate 110 is disposed within a mounting groove 130. The inner longitudinal beam plate 110 and the outer longitudinal beam plate 120 are respectively provided with opposing first connecting edges 111 and 121 on one side in the vertical direction Z. A first fixing member 400 sequentially passes through and fixes the first connecting edge 121 of the outer plate, the first connecting edge 111 of the inner plate, a second connecting portion 320, and a connecting side plate 2213. The front longitudinal beam 100 includes an inner longitudinal beam plate 110 and an outer longitudinal beam plate 120. The inner longitudinal beam plate 110 is disposed within a mounting groove 130 and is connected to the main body plate 2211. One end of each of the two connecting side plates 2213 is connected to a corresponding bent side plate 2212, and the other ends of the two connecting side plates 2213 are respectively set away from the opposite connecting side plate 2213. The outer plate 120 of the longitudinal beam is connected to the two connecting side plates 2213, thereby increasing the number of connection points between the front longitudinal beam 100 and the lower cross beam 200 and improving the strength and stability of the connection between the front longitudinal beam 100 and the connector 220. Specifically, the inner plate 110 of the longitudinal beam is provided with an inner plate first connecting edge 111, which is located at the end of the inner plate 110 of the longitudinal beam near the damping tower 300 in the vertical direction Z. The outer plate 120 of the longitudinal beam is provided with a first connecting edge 121. The first connecting edge 121 is located at the end of the outer plate 120 of the longitudinal beam near the damping tower 300 in the vertical direction Z. The first connecting edge 111 of the inner plate and the first connecting edge 121 of the outer plate are arranged opposite to each other and are connected by welding. The portions of the first connecting edge 111 of the inner plate and the first connecting edge 121 of the outer plate corresponding to the connecting side plate 2213 are located on the side of the connecting side plate 2213 away from the bent side plate 2212. The second connecting portion 320 of the damping tower 300 is located between the first connecting edge 111 of the inner plate and the connecting side plate 2213, so as to clamp the second connecting portion 320 between the first connecting edge 111 of the inner plate and the damping tower 300, thereby improving the stability of the connection between the damping tower 300 and the connector 220 and the front longitudinal beam 100 in the transverse direction Y. The first fastener 400 is sequentially inserted through the first connecting edge 121 of the outer plate, the first connecting edge 111 of the inner plate, the second connecting part 320, and the connecting side plate 2213, forming a first fastener 400 that inserts four layers of plates to fix the shock absorber tower 300, the inner plate 110 of the longitudinal beam, the outer plate 120 of the longitudinal beam, and the lower crossbeam 200. In this way, the connection strength and stability between the shock absorber tower 300, the front longitudinal beam 100, and the lower crossbeam 200 can be effectively improved.

[0047] In this embodiment, the inner plate 110 of the longitudinal beam may include an inner plate main body plate 2211 and two inner plate side plates. The inner plate main body plate 2211 is connected to an inner plate side plate on each side in the vertical direction Z. The two inner plate side plates extend toward the longitudinal beam outer plate 120 in the horizontal direction Y. The first connecting edge 111 of the inner plate is connected to the side of the inner plate side plate that is close to the shock absorber tower 300 away from the inner plate main body plate 2211. The two inner plate side plates are respectively arranged opposite to the corresponding bent side plate 2212. The outer plate 120 of the longitudinal beam includes an outer plate main body plate 2211. The first connecting edge 121 of the outer plate is connected to the end of the outer plate main body plate 2211 near the damping tower 300. The outer plate 120 of the longitudinal beam is arranged opposite to the inner plate 110 of the longitudinal beam and is connected to each other through the first connecting edge 121 of the outer plate and the first connecting edge 111 of the inner plate, so that the inner plate 110 of the longitudinal beam and the outer plate 120 of the longitudinal beam form an internal cavity to improve the structural strength of the front longitudinal beam 100. The second connecting part 320 is spaced apart from the first connecting part 310 in the transverse direction Y, thereby improving the connection strength and stability between the damping tower 300 and the front longitudinal beam 100.

[0048] In some embodiments, the front frame 10 further includes a second fastener 510, which is spaced apart from the connecting side plate 2213 in the vertical direction Z. The second fastener 510 sequentially passes through and fixes the outer plate first connecting edge 121, the inner plate first connecting edge 111, and the second connecting portion 320. The front frame 10 also includes a second fastener 510, which is spaced apart from the connecting side plate 2213 in the vertical direction Z, and thus also spaced apart from the first fastener 400. The second fastener 510 is located in the vertical direction Z in the direction away from the first fastener 400 from the bent side plate 2212. The second fastener 510 sequentially passes through the outer plate first connecting edge 121, the inner plate first connecting edge 111, and the second connecting portion 320 of the shock absorber tower 300, so as to fix the second connecting portion 320 on the upper part of the first fastener 400, the inner plate first connecting edge 111, and the outer plate first connecting edge 121. Therefore, two fixing points can be formed in the second connecting part 320, namely at the first fixing member 400 and the second fixing member 510. The first fixing member 400 fixes the inner plate 110 of the longitudinal beam, the outer plate 120 of the longitudinal beam, the second connecting part 320 and the connector 220. The second fixing member 510 only fixes the inner plate 110 of the longitudinal beam, the outer plate 120 of the longitudinal beam and the second connecting part 320, thereby increasing the force transmission path. When subjected to a large impact force, the impact force first passes through one of the points to achieve the purpose of attenuating the impact force, and then passes through the other point to absorb the impact force. Thus, the impact force can be absorbed step by step, improving the impact performance of the front frame 10.

[0049] See Figure 8 and Figure 9 , Figure 8 yes Figure 7A schematic diagram of one embodiment of the lower crossbeam is shown. Figure 9 yes Figure 8 An enlarged structural diagram at point E (dashed box).

[0050] In some embodiments, the connector 220 includes a support plate 2214, one end of which is connected to the end of the main body plate 2211 away from the second connecting portion 320. The inner plate 110 and outer plate 120 of the longitudinal beam include opposing inner plate second connecting edges 112 and outer plate second connecting edges 122 on the other side in the vertical direction Z. A third fastener passes through the outer plate second connecting edge 122, the inner plate second connecting edge 112, and the connecting side plate 2213 in sequence. The other end of the support plate 2214 extends along the surface of the lower crossbeam 200 in the vertical direction Z, away from the main body plate 2211. The support plate 2214, the bent side plate 2212, and the connecting side plate 2213 form a first collapse space 530. The inner plate 110 of the longitudinal beam includes an inner plate second connecting edge 112, which is located on the side of the inner plate 110 in the vertical direction Z away from the inner plate first connecting plate. The outer plate 120 of the longitudinal beam includes a second connecting edge 122, which is located on the side of the outer plate 120 in the vertical direction Z away from the first connecting plate. Specifically, the second connecting edge 112 of the inner plate can be connected to the end of the inner plate side plate away from the inner plate main body plate 2211, and the second connecting edge 122 of the outer plate is connected to the end of the outer plate main body plate 2211 away from the first connecting edge 121. The second connecting edge 112 of the inner plate and the second connecting edge 122 of the outer plate are opposite to each other and connected. A third fastener is sequentially inserted and fixed to the second connecting edge 122 of the outer plate, the second connecting edge 112 of the inner plate, and the connecting side plate 2213, so that both sides of the front longitudinal beam 100 in the vertical direction Z are fixedly connected to one connecting side plate 2213 of the connector 220, thereby improving the connection strength and connection stability between the front longitudinal beam 100 and the lower cross beam 200. In addition, the connector 220 includes a support plate 2214. One end of the support plate 2214 is connected to the end of the main body plate 2211 away from the second connecting part 320. The other end of the support plate 2214 extends along the surface of the lower crossbeam 200 in the vertical direction Z in a direction away from the main body plate 2211. The support plate 2214 is connected to the lower crossbeam 200 so that the support plate 2214 is supported between the lower crossbeam 200 and the main body plate 2211, thereby improving the structural strength of the connector 220 and improving the impact resistance of the connector 220. The support plate 2214 also protrudes from the bent side plate 2212 in the vertical direction Z, and part of the support plate 2214 is also arranged opposite to the connecting side plate 2213, so that the support plate 2214, the bent side plate 2212 and the connecting side plate 2213 cooperate to form the first collapse space 530, so as to further improve the structural strength of the connector 220. The inner plate second connecting edge 112 and the outer plate second connecting plate are fixedly connected to the connecting side plate 2213 through the third fastener, so that when the inner plate second connecting edge 112, the outer plate second connecting plate and the second connecting part 320 are subjected to force, the impact force can also be transmitted to the first collapse space 530, which can improve the impact performance of the connection between the front longitudinal beam 100 and the connector 220.

[0051] In some embodiments, the lower crossbeam 200 includes a first reinforcing rib 2215. The first reinforcing rib 2215 extends in the longitudinal direction X. A portion of the first reinforcing rib 2215 is disposed on the crossbeam body 210, and another portion extends to one side of the bent side plate 2212 near the second connecting portion 320, corresponding to the main body plate 2211. The first reinforcing rib 2215, the bent side plate 2212, and the connecting side plate 2213 form a second collapse space 540. The first reinforcing rib 2215 extends in the longitudinal direction X. A portion of the first reinforcing rib 2215 extends on the crossbeam body 210, and another portion extends in the longitudinal direction X to one side of the bent side plate 2212 near the second connecting portion 320. The first reinforcing rib 2215 protrudes from the bent side plate 2212 and the crossbeam body 210 in the vertical direction Z, so that the first reinforcing rib 2215 can strengthen the connection between the connector 220 and the crossbeam body 210. The first reinforcing rib 2215 located on the bent side plate 2212 is correspondingly connected to the main plate 2211 so that the main plate 2211 can transfer the impact force to the first reinforcing rib 2215. In addition, the first reinforcing rib 2215 also forms a second collapse space 540 with the adjacent bent side plate 2212 and connecting side plate 2213, thereby further improving the structural strength and impact performance of the connector 220. There can be multiple first reinforcing ribs 2215, which are spaced apart in the transverse direction Y. Some of the first reinforcing ribs 2215 extend in the longitudinal direction X, and some are located on the crossbeam body 210, some are located on the bent side plate 2212, and other parts of the first reinforcing ribs 2215 are located on the crossbeam body 210, so as to improve the structural strength of the connector 220 and the crossbeam body 210 within a certain range.

[0052] In some embodiments, the front frame 10 includes a plurality of second reinforcing ribs 2216, which are connected between the main body plate 2211 and the crossbeam body 210. The plurality of second reinforcing ribs 2216 are spaced apart in the vertical direction Z, and two adjacent second reinforcing ribs 2216 and the main body plate 2211 form a third collapse space 550. The front frame 10 includes a plurality of second reinforcing ribs 2216, which are disposed between the main body plate 2211 and the crossbeam body 210. Specifically, multiple second reinforcing ribs 2216 are connected to the main body plate 2211 and protrude from the side of the main body plate 2211 away from the inner plate 110 of the longitudinal beam in the transverse direction Y. Multiple second reinforcing ribs 2216 are also connected to the side of the crossbeam body 210 near the connector 220 and protrude from the crossbeam body 210 in the longitudinal direction X. The multiple second reinforcing ribs 2216 are spaced apart in the vertical direction Z, so that adjacent reinforcing ribs, the main body plate 2211, and the crossbeam body 210 form a third collapse space 550, which can improve the strength and stability of the connection between the connector 220 and the crossbeam body 210. The spaced arrangement of multiple reinforcing ribs can also form multiple third collapse spaces 550.

[0053] In some embodiments, there are two connectors 220, which are positioned opposite each other and spaced apart in the transverse direction Y. The main body of the crossbeam 210 is provided with a fourth collapse space 560 extending in the transverse direction Y. At least one third collapse space 550 is connected to each end of the fourth collapse space 560 in the transverse direction Y. The two connectors 220 are positioned opposite each other and spaced apart, and each connector 220 is connected to a front longitudinal beam 100, so that the impact force on the two connectors 220 is more symmetrical, improving the stability of the front frame 10. The main body of the crossbeam 210 is provided with a fourth collapse space 560 extending in the transverse direction Y on the side near the connector 220. The fourth collapse space 560 can be understood as a groove structure in the longitudinal direction X of the crossbeam 210 facing away from the connector 220, which can improve the structural strength of the main body of the crossbeam 210. The fourth collapse space 560 is located between the two connectors 220, and both ends of the fourth collapse space 560 in the lateral direction Y are connected to at least one third collapse space 550 of their respective connectors 220. When subjected to an impact force in the lateral direction Y, the impact force from the side of one connector 220 can be transmitted to the other connector 220 through the third collapse space 550 and the fourth collapse space 560, thereby improving the side impact performance of the front frame 10. In addition, reinforcing ribs that intersect in the longitudinal direction X and the lateral direction Y can be provided in the fourth collapse space 560 to further improve the structural strength of the beam body 210.

[0054] In some embodiments, both ends of the front longitudinal beam 100 in the vertical direction Z have gaps with the bent side plates 2212, so that a fifth collapse space 570 is formed between the two sides of the front longitudinal beam 100 in the vertical direction Z and the corresponding bent side plates 2212. Specifically, the gaps between the two ends of the front longitudinal beam 100 in the vertical direction Z and the bent side plates 2212 are formed by the inner plate side plates of the inner plate 110 of the front longitudinal beam 100 and the bent side plates 2212 being spaced apart to form gaps, so that the two sides of the front longitudinal beam 100 in the vertical direction Z cooperate with the connector 220 to form a fifth collapse space 570, thereby improving the impact performance of the front frame 10 in the longitudinal direction X.

[0055] In some embodiments, the shock absorber tower 300 further includes a third connecting portion located at the end of the shock absorber tower 300 away from the second connecting portion 320 in the longitudinal direction X. An inner plate protrusion is provided at the position corresponding to the first connecting edge 111 of the inner plate and the third connecting portion, and an outer plate protrusion is provided at the position corresponding to the first connecting edge 121 of the outer plate and the third connecting portion. Part of the inner plate protrusion is disposed opposite to the outer plate protrusion and is fixed by a fourth fastener. Another part of the inner plate protrusion is disposed corresponding to the third connecting portion and is fixed by another fastener. Therefore, upon impact, since part of the inner plate protrusion is directly connected to the third connecting portion, and part of the inner plate protrusion is connected to the outer plate protrusion and the third connecting portion, the impact force can be absorbed step-by-step at the third connecting portion, reducing the risk of damage to the third connecting portion under excessive impact force and improving impact performance.

[0056] In summary, the shock absorber tower 300 is provided with a first connecting part 310 and a second connecting part 320 in sequence along the longitudinal direction X. The first connecting part 310 is connected to the front longitudinal beam 100, and the second connecting part 320 is fixedly connected to the connector 220 of the front longitudinal beam 100 and the lower cross beam 200 through the first fastener 400, thereby improving the connection strength and stability between the front longitudinal beam 100, the lower cross beam 200 and the shock absorber tower 300, and improving the vehicle's collision performance.
