Description
Technical Field
[0001] This utility model relates to the field of automotive parts, and in particular to a front longitudinal beam inner plate structure and a vehicle having the same. Background Technology
[0002] The front longitudinal beam structure of a car has a significant impact on collision safety, overall vehicle NVH (noise, vibration, and harshness), body modal characteristics, and body rigidity. Especially in frontal collisions, the front longitudinal beam structure plays a crucial role in transmitting and absorbing impact forces and energy, reducing injuries to the driver and occupants. It also shares the load-bearing burden for components such as the engine, motor, and electronic control systems in the front compartment. In traditional designs, the reinforcing plates in the inner panels of the front longitudinal beam use a Z-shaped structure, only connecting the inner panels in the Y-direction. This design has relatively poor strength and struggles to simultaneously meet the rigidity requirements of the engine mount points and front subframe mount points, as well as the requirements for bending deformation of the front longitudinal beam during a collision.

The inner plate reinforcing plate 20 is connected to the front subframe mounting plate 30 and the engine mount mounting plate 40, and the inner plate reinforcing plate 20 is provided with a crumple zone 50. The front longitudinal beam inner plate structure provided by this utility model, by providing an inner plate reinforcing plate 20 on the front longitudinal beam inner plate body 10 and connecting the inner plate reinforcing plate 20 to the front subframe mounting plate 30 and the engine mount mounting plate 40 respectively, can improve the rigidity of the front longitudinal beam inner plate body, as well as the rigidity of the engine mount mounting point and the front subframe mounting point. Furthermore, because the inner plate reinforcing plate 20 is provided with a crumple zone 50, it can also guide the front longitudinal beam inner plate body 10 during a collision, ensuring that the front longitudinal beam inner plate body 10 can bend and deform.
[0022] Furthermore, the engine mount plate 40, the inner plate reinforcing plate 20, and the front subframe mount plate 30 are disposed on the front longitudinal beam inner plate body 10 along the length direction of the front longitudinal beam inner plate body 10, and the inner plate reinforcing plate 20 is disposed between the front subframe mount plate 30 and the engine mount plate 40. The engine mount plate 40 is used to mount the engine mount, the front subframe mount plate 30 is used to mount the front subframe, and the inner plate reinforcing plate 20 is used to improve the rigidity and strength of the front longitudinal beam inner plate body 10; since the inner plate reinforcing plate 20 is also connected to the front subframe mount plate 30 and the engine mount plate 40 respectively, it can also improve the rigidity and strength of the engine mount mounting point and the front subframe mounting point.
[0023] Please refer to the following: Figure 1 The inner plate body 10 of the front longitudinal beam includes a first inner plate body 11, a second inner plate body 12, and a third inner plate body 13. The first inner plate body 11 and the second inner plate body 12 extend from both ends of the third inner plate body 13 in the width direction away from the third inner plate body 13. That is, the first inner plate body 11, the second inner plate body 12, and the third inner plate body 13 are connected to form a U-shaped structure, which facilitates connection with the outer plate of the front longitudinal beam to form an internal cavity structure. It should be noted that the outer plate structure of the front longitudinal beam is not shown in the figure.
[0024] Specifically, the front subframe mounting plate 30 is mounted on the third body 13 of the front longitudinal beam inner plate, the engine mount mounting plate 40 is mounted on the third body 13 and the second body 12 of the front longitudinal beam inner plate, and the inner plate reinforcing plate 20 is mounted on the first body 11, the second body 12, and the third body 13 of the front longitudinal beam inner plate. Since the inner plate reinforcing plate 20 is connected to the first body 11, the second body 12, and the third body 13 of the front longitudinal beam inner plate, the rigidity and strength of the front longitudinal beam inner plate body 10 can be improved.
[0025] Please see Figure 3The inner panel reinforcing plate 20 specifically includes a central portion 21 and a first end 22, a second end 23, a third end 24, and a fourth end 25 disposed on the central portion 21. The first end 22 and the second end 23 are respectively disposed at both ends of the central portion 21 along the length direction of the inner panel body 10 of the front longitudinal beam, and the third end 24 and the fourth end 25 are respectively disposed at both ends of the central portion 21 along the width direction of the inner panel body 10 of the front longitudinal beam. The central portion 21 is integrally connected to the third body 13 of the inner panel of the front longitudinal beam. The first end 22 and the second end 23 are arranged parallel to the central portion 21 and are respectively connected to the front subframe mounting plate 30 and the engine mount mounting plate 40. The third end 24 and the fourth end 25 are both folded over the central portion 21 and are respectively connected to the first body 11 and the second body 12 of the inner panel of the front longitudinal beam. Therefore, the inner plate reinforcing plate 20 can improve the rigidity of the third body 13 of the front longitudinal beam inner plate, the first end 22 and the second end 23 can improve the rigidity of the front subframe mounting point and the engine mount mounting point, and the third end 24 and the fourth end 25 can improve the rigidity of the first body 11 of the front longitudinal beam inner plate and the second body 12 of the front longitudinal beam inner plate.
[0026] Furthermore, the crumple zone 50 includes a first crumple zone 51 and a second crumple zone 52. The first crumple zone 51 extends from the middle portion 21 of the reinforcing plate to the third end portion 24, and the second crumple zone 52 extends from the middle portion 21 of the reinforcing plate to the fourth end portion 25. The arrangement of the first crumple zone 51 and the second crumple zone 52 can guide the inner plate body 10 of the front longitudinal beam during a vehicle collision, ensuring that the inner plate body 10 of the front longitudinal beam can bend and deform.
[0027] As described above, the front longitudinal beam inner plate structure provided by this utility model improves the rigidity of the front longitudinal beam inner plate body, as well as the rigidity of the engine mount point and the front subframe mount point, by setting an inner plate reinforcing plate 20 on the inner plate body 10 and connecting the inner plate reinforcing plate 20 to the front subframe mounting plate 30 and the engine mount mounting plate 40 respectively. Furthermore, since a crumple zone 50 is provided on the inner plate reinforcing plate 20, it can also guide the front longitudinal beam inner plate body 10 during a collision, ensuring that the front longitudinal beam inner plate body 10 can bend and deform.
