The following describes a front hatch structure 1 according to an embodiment of the invention with reference to the drawings.
As shown in fig. 1 to 2, the front cabin structure 1 includes a front impact beam 100, a front side member 200, a primary energy absorption box 300, and a side member pillar 400.
The front impact beam 100 is configured with an extension at an end thereof, the main energy absorption box 300 is connected between the front impact beam 100 and the front side member 200, for example, the main energy absorption box 300 and the front impact beam 100 may be welded, and the side member pillar 400 is connected to an outer side of the front side member 200. For example, the side member pillar 400 and the front side member 200 may be welded, and the long section may overlap the side member pillar 400 when the front impact beam 100 is subjected to a small offset collision.
The front deck structure 1 can be applied to a vehicle with a small wheel track and a large wheel package.
It is understood that the front cabin structure 1 has a front side member 200, a main crash box 300, and a side member pillar 400 on each of the left and right sides thereof. The following description is given by way of example of the structures of the front longitudinal beam 200, the main crash box 300 and the longitudinal beam column 400 on the left side of the front cabin structure 1, wherein the structures of the front longitudinal beam 200, the main crash box 300 and the longitudinal beam column 400 on the right side of the front cabin structure 1 can refer to the structures of the front longitudinal beam 200, the main crash box 300 and the longitudinal beam column 400 on the left side of the front cabin structure 1.
According to the front cabin structure 1 of the embodiment of the invention, the main energy absorption box 300 is connected between the front anti-collision beam 100 and the front longitudinal beam 200, when the front anti-collision beam 100 collides, the force of the front anti-collision beam 100 is transmitted to the front longitudinal beam 200 through the main energy absorption box 300, the main energy absorption box 300 deforms to absorb energy and buffer, the force applied to the front longitudinal beam 200 is greatly reduced, and further, the energy required to be absorbed by the front longitudinal beam 200 is reduced, and the safety is high.
Further, by connecting the side member pillar 400 to the outer side of the front side member 200, the side member pillar 400 can support the front side member 200 in the vertical 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 colliding object 2 of the vehicle in the left-right direction of the vehicle, and particularly, when a small offset collision occurs to the vehicle, the main energy absorption box 300 can be crushed and hit against the side member pillar 400, and the side member pillar 400 can guide the hitting force to the front side member 200 after the collision, so that the front side member 200 is bent to absorb the power and transmit the power toward the rear of the vehicle after the collision occurs to the vehicle, and the absorption power of the front cabin structure 1 is further increased, whereby the front cabin structure 1 can effectively absorb the collision power, and the safety is higher.
Further, by providing the side member pillar 400, the vehicle is configured to have a short front overhang, the dimension of the front side member 200 in the lateral direction of the vehicle is small, and the collision object 2 can sufficiently overlap with the front side member 200.
By arranging the extension part, when a small offset collision occurs to a vehicle, the extension part can be bent and lapped on the longitudinal beam upright 400, the longitudinal beam upright 400 supports the extension part, and the extension part and the front anti-collision beam 100 are relatively inclined, so that the collision object 2 can continuously slide relative to the vehicle on the surface of the extension part, the risk that the collision object 2 is directly clamped on the longitudinal beam upright 400 is reduced, the mounting stability of the longitudinal beam upright 400 can be greatly improved, the damage to components in the longitudinal beam upright 400 is reduced, the capability of the vehicle for resisting the small offset collision is further improved, and the safety is improved.
Thus, the front cabin structure 1 according to the present invention can effectively absorb the collision ability, and has the advantages of strong ability to resist small offset collision and high safety.
According to some embodiments of the present invention, the distance between the point of attachment of the front impact beam 100 and the primary energy absorption box 300 and the outer side surface of the side member pillar 400 is less than the length of the extension. Wherein, the front impact beam 100 can be directly overlapped on the outer side surface of the longitudinal beam column 400.
Here, in the case of one end portion of the impact beam 100, the extension portion formed at the one end portion is a portion from the outer end surface of the one end portion to the main crash box 300 closest to the one end portion.
Therefore, the extension is more stably and reliably lapped with the longitudinal beam upright 400 after being bent, so that the collision object 2 can slide along the surface of the extension more smoothly, and the collision object 2 is further prevented from being directly clamped at the longitudinal beam upright 400.
According to some embodiments of the present invention, as shown in fig. 6, the front cabin structure 1 further includes a secondary energy absorption box 800, the secondary energy absorption box 800 is disposed outside the primary energy absorption box 300, and the secondary energy absorption box 800 is connected to the front impact beam 100 and the longitudinal beam pillar 400 respectively.
For example, after the impact object 2 contacts the front impact beam 100, the front impact beam 100 is bent and deformed, then the auxiliary energy absorption box 800 starts to deform under stress, after the auxiliary energy absorption box 800 is completely deformed, the impact object 2 contacts the longitudinal beam upright 400 and pushes the longitudinal beam upright 400, the longitudinal beam upright 400 transmits force to the front longitudinal beam 200, and the front longitudinal beam 200 is bent and deformed along the left and right directions of the vehicle to absorb energy. Thus, by arranging the auxiliary energy absorption box 800, the auxiliary energy absorption box 800 can participate in deformation energy absorption to increase 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 longitudinal beam pillar 400 and the front longitudinal beam 200, respectively. For example, the web 500 may be connected to the side member pillar 400 and the front side member 200 by threaded fasteners, respectively. When longeron stand 400 and front longeron 200 welding point separation like this, longeron stand 400 and front longeron 200 all can be limited position by connecting plate 500, are favorable to increasing longeron stand 400 and front longeron 200's joint strength, and then have increased front deck structure 1's structural stability.
According to some embodiments of the present invention, as shown in fig. 1, 2, and 6, the main crash box 300 includes a main box body 310, a main box body front connection plate 320, and a main box body rear connection plate 330. The main case front connection plate 320 is connected to the front end of the main case 310 and is coupled to the front impact beam 100, and the main case rear connection plate 330 is connected to the rear end of the main case 310 and is coupled thereto.
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. Thus, the main energy-absorbing box 300 is directly connected with the front anti-collision beam 100 and the front longitudinal beam 200, which is beneficial for the front anti-collision beam 100 to transmit collision force to the front longitudinal beam 200 through the main energy-absorbing box 300, so that the whole 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 rail 200 includes a side rail inner panel 210, a side rail outer panel 220, and a side rail front connecting panel 230. The side member outer panel 220 is connected to the outer side of the side member inner panel 210, the side member front connecting plate 230 is connected to the front end of the side member inner panel 210 and the front end of the side member outer panel 220, and the side member front connecting plate 230 is connected to the main crash box 300.
For example, the inner stringer plate 210 and the outer stringer plate 220 may be welded, the inner stringer plate 210 and the outer stringer plate 220 are welded, the front stringer connecting plate 230 is welded, and the front stringer connecting plate 230 is connected to the rear main box connecting plate 330. Thus, the front longitudinal beam 200 is arranged in a split manner, so that the difficulty of processing and demolding of the front longitudinal beam 200 can be reduced, the front longitudinal beam 200 is conveniently connected with the main energy absorption box 300, and the integral bending resistance of the front longitudinal beam 200 is favorably improved.
According to some embodiments of the invention, as shown in fig. 4 and 6, the front cabin structure 1 further comprises a front wheel house roof rail 600 and a wheel house pillar 700. The wheel house pillar 700 is connected to the front side member 200 and the front wheel house roof side member 600, respectively. Through setting up wheel house stand 700, front longitudinal 200's power can transmit front wheel house roof beam 600, and like this, front wheel house roof beam 600 also can absorb the collision of vehicle, and the holistic energy absorption of front deck structure 1 is more, and the security is higher.
Further, the front wheel house roof side rail 600 is connected to the longitudinal beam column 400, and the longitudinal beam column 400 and the front wheel house roof side rail 600 may be welded. Therefore, more energy absorption and force transmission can be carried out on the front longitudinal beam 200, the longitudinal beam upright column 400 can transmit force to the front longitudinal beam 200 and the front wheel cover upper side beam 600, two energy absorption paths exist in the sliding process of the collision object 2 to the rear side of the vehicle, and the energy absorption capacity of the front cabin structure 1 is higher.
For example, after the collision object 2 contacts the front collision-proof beam 100, the front collision-proof beam 100 is bent and deformed, then the auxiliary energy-absorbing box 800 starts to be stressed and deformed, after the auxiliary energy-absorbing box 800 is completely deformed, the collision object 2 contacts the longitudinal beam upright 400 and pushes the longitudinal beam upright 400, the longitudinal beam upright 400 transmits force to the front longitudinal beam 200, the front longitudinal beam 200 is bent and deformed along the left and right direction of the vehicle to absorb energy, meanwhile, the front wheel cover upper side beam 600 starts to crush and absorb energy due to the welding of the longitudinal beam upright 400 and the front wheel cover upper side beam 600, and finally the front wheel cover upper side beam 600 transmits force to the A column, so that the front cabin structure 1 finishes force transmission and energy absorption.
Therefore, the force transmission path of the front cabin structure 1 is complete, and the whole stability and energy absorption capacity of the front cabin structure 1 are high.
According to some embodiments of the present invention, as shown in fig. 6, the stringer pillar 400 includes a pillar plate 410, an upper brace plate 420, a lower brace plate 430, and an upper closure plate 440.

Thus, the longitudinal beam column 400 can form a closed space, the cross section of the longitudinal beam column 400 is annular, and the longitudinal beam column 400 is high in bending resistance and beneficial to force transmission among the front longitudinal beam 200, the auxiliary energy absorption box 800 and the front wheel cover upper side beam 600.
According to some embodiments of the present invention, as shown in fig. 6, the secondary crash box 800 includes a secondary box body 810, a secondary box body front connection plate 820, and a secondary box body rear connection plate 830.

The auxiliary box body 810 and the rear connecting plate 500 of the auxiliary energy absorption box 800 can be welded, and threaded fasteners in the left and right directions of a vehicle can be added between the auxiliary box body 810 and the rear connecting plate 500 of the auxiliary energy absorption box 800 in a welding mode, so that the structural stability of the auxiliary energy absorption box 800 in the left and right directions of the vehicle is improved. Thus, the auxiliary energy-absorbing box 800 is directly connected with the front anti-collision beam 100 and the longitudinal beam upright column 400, so that the front anti-collision beam 100 transmits collision force to the longitudinal beam upright column 400 through the auxiliary energy-absorbing box 800, the whole stress of the front cabin structure 1 is more uniform, and the safety is further improved.
