For example, the rail pillar 400 and the front rail 200 may be welded, and the extension portion overlaps the rail pillar 400 when the front impact beam 100 is subjected to a small offset collision.
The front deck structure 1 may be suitable for a vehicle with a small track and a large wheel package.
It will be appreciated that the front deck structure 1 has a front side rail 200, a main crash box 300 and a rail pillar 400 on both the left and right sides. The following description is given by way of example of the structure of the front side member 200, the main crash box 300 and the side member pillar 400 on the left side of the front deck structure 1, wherein the structure of the front side member 200, the main crash box 300 and the side member pillar 400 on the right side of the front deck structure 1 may be referred to as the structure of the front side member 200, the main crash box 300 and the side member pillar 400 on the left side of the front deck structure 1.
According to the front cabin structure 1 of the embodiment of the present invention, by connecting the main crash box 300 between the front impact beam 100 and the front side frame 200, when the front impact beam 100 collides, the force of the front impact beam 100 is transmitted to the front side frame 200 through the main crash box 300, the main crash box 300 deforms to absorb and buffer, the force applied to the front side frame 200 is greatly reduced, and the energy required to be absorbed by the front side frame 200 is reduced, so that the safety is high.
In addition, by connecting the side member pillar 400 to the outside of the front side member 200, the side member pillar 400 can support the front side member 200 in the up-down direction of the vehicle, and further the side member pillar 400 can indirectly increase the overlapping dimension of the front side member 200 and the collided object 2 of the vehicle in the left-right direction of the vehicle, especially when the vehicle is in a small offset collision, the main energy-absorbing box 300 can strike the side member pillar 400 after being crushed, the side member pillar 400 can guide the striking force to the front side member 200 after being struck, so that the front side member 200 is bent to absorb energy after the vehicle is collided and transmit force towards the rear of the vehicle, and the energy absorption amount of the front cabin structure 1 is further increased, thereby the front cabin structure 1 can effectively absorb the collision capability, and the safety is higher.
Further, by providing the side member pillar 400, the vehicle is configured to have a short front suspension, the size of the front side member 200 in the lateral direction of the vehicle is small, and the striker 2 can sufficiently overlap the front side member 200.
Through setting up the extension, when the vehicle took place little offset collision, the extension can take place to bend and overlap joint at longeron stand 400, longeron stand 400 forms the support to the extension this moment, and the relative slope between extension and the preceding crashproof roof beam 100, so the collision thing 2 can continue to slide for the vehicle at the surface of extension to reduce the risk of collision thing 2 direct card in longeron stand 400 department, thereby can greatly improve longeron stand 400's installation stability and reduced the damage of longeron stand 400 inner part, further increased the vehicle and resisted little offset collision's ability, improved the security.
In this way, the front cabin structure 1 according to the present invention can effectively absorb the collision capability, and has the advantages of strong capability of resisting the small offset collision and high safety.
According to some embodiments of the invention, the distance between the connection point of the front impact beam 100 and the main crash box 300 and the outer side of the rail pillar 400 is less than the length of the extension. Wherein, the front impact beam 100 may directly overlap the outer side surface of the rail pillar 400.
Here, an extension formed at one end of the previous impact beam 100 is a portion between the outer end surface of the one end and the main crash box 300 closest to the one end, for example.
In this way, the extension part is bent and then is overlapped with the longitudinal beam upright post 400 more stably and reliably, so that the collider 2 slides along the surface of the extension part more smoothly, and the collider 2 is further prevented from being directly clamped at the longitudinal beam upright post 400.
According to some embodiments of the present invention, as shown in fig. 6, the front cabin structure 1 further includes a secondary crash box 800, the secondary crash box 800 being disposed outside the primary crash box 300, the secondary crash box 800 being connected to the front impact beam 100 and the side rail pillar 400, respectively.
For example, after the collider 2 contacts the front bumper beam 100, the front bumper beam 100 is bent and deformed, then the auxiliary crash box 800 begins to deform under force, after the auxiliary crash box 800 is completely deformed, the collider 2 contacts the rail pillar 400 and pushes the rail pillar 400, the rail pillar 400 transfers force to the front rail 200, and the front rail 200 is bent and deformed along the left-right direction of the vehicle to absorb energy. In this way, by arranging the auxiliary energy absorption box 800, the auxiliary energy absorption box 800 can participate in deformation energy absorption so as to increase the energy absorption space.
According to some embodiments of the present invention, as shown in fig. 1, the front cabin structure 1 further includes a connection plate 500, and the connection plate 500 is connected to the side rail pillar 400 and the front side rail 200, respectively. For example, the web 500 may be connected to the rail pillar 400 and the front rail 200, respectively, by threaded fasteners. When the welding points of the longitudinal beam stand column 400 and the front longitudinal beam 200 are separated, the longitudinal beam stand column 400 and the front longitudinal beam 200 can be limited in position by the connecting plate 500, so that the connection strength of the longitudinal beam stand column 400 and the front longitudinal beam 200 is increased, and the structural stability of the front cabin structure 1 is further improved.

The main box front connection plate 320 is connected to the front end of the main box 310 and to the front impact beam 100, and the main box rear connection plate 330 is connected to the rear end of the main box 310 and to the front impact beam 100.
For example, the main case 310 and the main case front connection plate 320 may be welded, and the main case 310 and the main case rear connection plate 330 may be welded. In this way, the main crash box 300 is directly connected with the front crash beam 100 and the front longitudinal beam 200, so that the front crash beam 100 is beneficial to transmitting collision force to the front longitudinal beam 200 through the main crash box 300, so that the overall stress of the front cabin structure 1 is more uniform, and the safety is further improved.
According to some embodiments of the present invention, as shown in fig. 6, the front side member 200 includes a side member inner panel 210, a side member outer panel 220, and a side member front connection panel 230.
