[0041] In this embodiment, the longitudinal beam strengthening member 1 improves the anti-collision strength of the front longitudinal beam 4 in the front engine compartment frame. Both ends of the cross beam strengthening member 2 are connected to the longitudinal beam strengthening member 1, which is used to increase the bending strength of the two front longitudinal beams 4 in the front engine compartment frame, and further enhance the side anti-collision strength of the front engine compartment frame.

[0042] Specifically, as Figure 3 and Figure 4 shown, in this embodiment, the cross beam strengthening member 2 has adjacent first cross panels 21, second cross panels 22 and third cross panels 23; the longitudinal beam strengthening member 1 has adjacent first longitudinal panels 11, second longitudinal panels 12 and third longitudinal panels 13; the connection assembly 5 includes a first strengthening member 51 and a second strengthening member 52 (see Figure 1 ); the first strengthening member 51 has a first strengthening portion 512 connected to the first cross panel 21 and a second strengthening portion 511 connected to the first longitudinal panel 11; the second strengthening member 52 has a first strengthening plate 521 connected to the second longitudinal panel 12. The first strengthening plate 521 has a first connecting plate 522 that bends and extends away from the second longitudinal panel 12 and is connected to the second cross panel 22, and a second connecting plate 523 connected to the third cross panel 23. It is worth mentioning that in this embodiment, both the first strengthening member 51 and the second strengthening member 52 are integrally formed structural members. Specifically, in this embodiment, both the first strengthening portion 512 and the first cross panel 21, and the second strengthening portion 511 and the first longitudinal panel 11 are connected by welding. Both the first strengthening plate 521 and the second longitudinal panel 12, the first connecting plate 522 and the second cross panel 22, and the second connecting plate 523 and the third cross panel 23 are connected by welding. In other embodiments, the welding connection can be replaced by a bolt connection. Therefore, this application does not make any restrictions and is set according to actual situations.

[0043] During actual use, the first reinforcing member 51 and the second reinforcing member 52 cooperate to achieve multiple fixed connections between the crossbeam reinforcing member 2 and the longitudinal beam reinforcing member 1, ensuring the bending strength of the longitudinal beam reinforcing member 1, further ensuring the anti-collision strength of the front engine compartment assembly, and thus ensuring the safety of the components inside the front engine compartment and the safety of the passengers in the vehicle.

[0045] During actual use, the first connecting plate 522 can transfer the extrusion force received by the longitudinal beam reinforcing member 1 to the second cross panel 22 and the first auxiliary plate 513. The bent first auxiliary plate 513 can reduce the extrusion force of the first connecting plate 522 on the second cross panel 22, avoiding the crushing of the second cross panel 22 by the first connecting plate 522 and ensuring the connection strength between the longitudinal beam reinforcing member 1 and the crossbeam reinforcing member 2. The first bending flanging 5141 can distribute the component force of the extrusion force transmitted by the first auxiliary plate 513 to the first cross panel flanging 24, avoiding the crushing of the front wall plate 3 by the first bending flanging 5141 and ensuring the safety of the front engine compartment assembly. Through the cooperation of the first connecting plate 522 and the first auxiliary plate 513, and the cooperation of the first bending flanging 5141 and the first cross panel flanging 24, the application improves the connection strength between the longitudinal beam reinforcing member 1 and the crossbeam reinforcing member 2 through a two-stage force distribution structure, and further improves the anti-collision strength of the front engine compartment assembly.

In this embodiment, the auxiliary strengthening member 53 disperses and transmits the impact force received by the front longitudinal beam 4 to the front wall panel 3, further improving the impact resistance of the front longitudinal beam 4 and enhancing the overall strength of the front engine compartment assembly to ensure the safety of passengers in the vehicle.

[0047] As Figure 4 and Figure 6 As shown, in a specific example provided in this embodiment, the first auxiliary strengthening plate 531 is provided with a second bending portion 5311, and a third limiting space 5312 for defining the position of the first strengthening plate 521 is formed between the second bending portion 5311 and the second longitudinal panel 12. The third transverse panel 23 has a third transverse flange 25 connected to the front wall panel 3; the third auxiliary strengthening plate 533 is provided with a third bending portion 5331, and a fourth limiting space 5332 for defining the position of the third transverse flange 25 is formed between the third bending portion 5331 and the front wall panel 3.

[0048] During actual use, a part of the impact force received by the side of the front longitudinal beam 4 is transmitted by the first connecting plate 522 to the cross beam strengthening member through the first strengthening plate 521 and finally transmitted to the front wall panel 3; a part of the impact force is transmitted to the front wall panel 3 through the first auxiliary strengthening plate 531; the two force-sharing structures ensure the anti-collision strength of the front longitudinal beam 4; the third bending portion 5331 divides the impact force received by the front of the front cross beam through the third transverse flange 25 to avoid crushing of the front wall panel 3 by the first auxiliary strengthening plate 531 and ensure the strength of the front engine compartment assembly.
