[0048] The embodiment of the present application provides a front compartment reinforcing structure, which improves the torsional stiffness of the front compartment of the vehicle.

[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0050] As Figures 1-9 shown, the front compartment reinforcing structure 100 provided by the embodiment of the present application includes a first cross beam 1 arranged along the transverse direction of the vehicle, both ends of the first cross beam 1 are connected to two front tower packages 200 of the vehicle; two inclined beams 2 are arranged obliquely relative to the longitudinal direction of the vehicle, one end of each inclined beam 2 is connected to the first cross beam 1, and the other end is connected to a front wall structure 300 of the vehicle; wherein a protruding section that arches upward is arranged in the middle of the first cross beam 1, the projection of the protruding section along the longitudinal direction of the vehicle and the projection of the front wall structure 300 along the longitudinal direction of the vehicle at least partially coincide.

[0051] It should be noted that the transverse direction of the vehicle, i.e. the Y direction, is the width direction of the vehicle, i.e. the left-right direction; the longitudinal direction of the vehicle, i.e. the X direction, is the length direction of the vehicle, i.e. the front-rear direction, as Figure 3 indicated by the arrow in the figure, the rear direction of the vehicle; the vertical direction of the vehicle, i.e. the Z direction, is the height direction of the vehicle, i.e. the vertical direction.

[0052] The projection of the protruding section along the longitudinal direction of the vehicle and the projection of the front wall structure 300 along the longitudinal direction of the vehicle at least partially coincide means that the projections of the protruding section and the front wall structure 300 along the longitudinal direction of the vehicle partially coincide or fully coincide.

[0053] The front compartment reinforcing structure 100 provided by the embodiment of the present application is connected between the two front tower packs 200 and the front wall structure 300 of the vehicle through the first cross beam 1 and the two inclined beams 2, and the rigidity and strength between the two front tower packs 200 and the front wall structure 300 of the vehicle are improved. Meanwhile, since the projection of the protruding section of the middle part of the first cross beam 1 along the longitudinal direction of the vehicle and the projection of the front wall structure 300 along the longitudinal direction of the vehicle at least partially coincide, the protruding section of the middle part of the first cross beam 1 serves as a main force transmission area and at least partially lies in the same plane as the front wall structure 300, which is beneficial to the transmission of load and enhances the rigidity and strength of the overall structure, and thus the torsional rigidity of the front compartment of the vehicle can be improved. Moreover, the first cross beam 1 after being arched has a relatively large space below, which is beneficial to the installation of the entire front compartment reinforcing structure 100.

[0054] In addition, the front tower pack 200 mainly bears Y and Z direction loads and is prone to large deformation or cracking due to insufficient connection strength under extreme working conditions. The embodiment of the present application adds the front compartment reinforcing structure 100 between the front tower packs 200, effectively improves the Y direction static and dynamic rigidity and connection strength of the front tower pack 200, and avoids the risk of cracking of the front tower pack 200 in the later period.

[0055] Preferably, the front compartment reinforcing structure 100 further comprises an auxiliary cross beam located between the first cross beam 1 and the front wall structure 300, and the auxiliary cross beam is connected with the inclined beams 2 and the front tower packs 200. The embodiment further improves the rigidity and strength between the two front tower packs 200 and the front wall structure 300 by connecting the middle parts of the two inclined beams 2 and the two front tower packs 200 through the auxiliary cross beam. Of course, the present application can also not be provided with the auxiliary cross beam, and the rigidity and strength of the first cross beam 1 and the two inclined beams 2 are increased to achieve the same effect of improving the rigidity and strength between the two front tower packs 200 and the front wall structure 300, and the present application does not make specific limitations in this regard.

[0056] In a specific embodiment, the auxiliary cross beam comprises two second cross beams 3 arranged along the lateral direction of the vehicle, one second cross beam 3 is connected between each inclined beam 2 and the adjacent front tower pack 200, the first end 31 of the second cross beam 3 is connected with the inclined beam 2, and the second end 32 of the second cross beam 3 is connected with the front tower pack 200; wherein the two inclined beams 2 are symmetrically arranged relative to the lateral center line of the vehicle; and the two second cross beams 3 are symmetrically arranged relative to the lateral center line of the vehicle.

[0057] As shown in Figures 1-4 The front compartment reinforcing structure 100 of the embodiment is left-right symmetrical, five reinforcing beams, i.e., the first cross beam 1, the two inclined beams 2 and the two second cross beams 3, are arranged in the main load transmission path between the front tower packs 200 and the front wall structure 300 and connected with the front tower packs 200 and the front wall structure 300, which can more fully adapt to the limited arrangement space and further improve the torsional rigidity and other performances; meanwhile, the five reinforcing beams and the vehicle body form five closed ring-shaped structure paths, as shown in Figure 2As shown in the middle color dashed box, the continuity of the structural rigidity is ensured, the rapid shunting and uniform transmission of the load are realized, and the risk of loosening of the connecting piece between the reinforcing beam and the front tower package 200 and the front wall structure 300 is reduced.

[0058] In order to facilitate processing and ensure structural strength, the above-mentioned five reinforcing beams are all extruded parts, specifically extruded aluminum alloy structures, and are spliced into a whole through welding between the beams. During installation, only the whole needs to be fixedly connected with the front tower package 200 and the front wall structure 300. Of course, the above-mentioned reinforcing beams can also be processed in other ways such as die casting or machining, as long as the corresponding rigidity and strength can be achieved.

[0059] Further, the first end 31 of the second cross beam 3 is arched relative to the second end 32, and a projection of the first end 31 of the second cross beam 3 along the vehicle transverse direction at least partially overlaps with a projection of a connecting region of the inclined beam 2 and the second cross beam 3 along the vehicle transverse direction. The above-mentioned at least partial overlap refers to partial overlap or complete overlap.

[0060] As shown in the middle color dashed box, the continuity of the structural rigidity is ensured, the rapid shunting and uniform transmission of the load are realized, and the risk of loosening of the connecting piece between the reinforcing beam and the front tower package 200 and the front wall structure 300 is reduced. Figures 4-6 As shown in the middle color dashed box, the continuity of the structural rigidity is ensured, the rapid shunting and uniform transmission of the load are realized, and the risk of loosening of the connecting piece between the reinforcing beam and the front tower package 200 and the front wall structure 300 is reduced.

[0061] In order to further optimize the above technical solution, the inclined beam 2 comprises a horizontal beam segment 22 connected with the water channel of the front wall structure 300, the horizontal beam segment 22 extending along the horizontal direction; an inclined beam segment 21 connected with the first cross beam 1, the inclined beam segment 21 being inclined downward relative to the horizontal direction from an end away from the first cross beam 1 to an end close to the first cross beam 1; an arc-shaped transition beam segment 23 smoothly connecting the horizontal beam segment 22 and the inclined beam segment 21, the arc-shaped transition beam segment 23 being connected with the first end 31 of the second cross beam 3.

[0062] As shown in the middle color dashed box, the continuity of the structural rigidity is ensured, the rapid shunting and uniform transmission of the load are realized, and the risk of loosening of the connecting piece between the reinforcing beam and the front tower package 200 and the front wall structure 300 is reduced. Figures 4-6 As shown in the middle color dashed box, the continuity of the structural rigidity is ensured, the rapid shunting and uniform transmission of the load are realized, and the risk of loosening of the connecting piece between the reinforcing beam and the front tower package 200 and the front wall structure 300 is reduced.

[0063] The water channel position of the front wall structure 300 is in front, facilitating the installation of the two inclined beams 2. Specifically, the two inclined beams 2 are connected to the water channel through bolts 5. In the embodiment, the force concentration area is transmitted to the path of the front cabin beam structure by adding the cross beam and inclined beam 2 structure between the front tower package 200 and the water channel, avoiding the strain energy concentration problem caused by force concentration.

[0064] In the front cabin reinforcing structure 100 provided by the above embodiment, the length of the horizontal beam section 22 is less than the length of the inclined beam section 21, and the length of the horizontal beam section 22 and the arc-shaped transition beam section 23 is the same as the length of the inclined beam section 21, as shown in Figure 6 The length of the horizontal beam section 22 and the arc-shaped transition beam section 23 can also be substantially the same as the length of the inclined beam section 21. The substantially same length means that the length difference is small and close to the same. In this way, the length of the inclined beam section 21 is relatively large, and the arch is relatively flat, which is beneficial for force transmission; at the same time, the length of the front section force receiving area formed by the inclined beam section 21 and the length of the rear section force receiving area formed by the horizontal beam section 22 and the arc-shaped transition beam section 23 are equivalent, which ensures the torsional stiffness of the vehicle front cabin. It can be understood that the horizontal beam section 22, the inclined beam section 21 and the arc-shaped transition beam section 23 can also adopt other length relationships as long as they are beneficial for force transmission, which will not be enumerated one by one in this application.

[0065] In order to facilitate assembly, the front cabin reinforcing structure 100 is connected to the front tower package 200 and the front wall structure 300 through bolts 5. Preferably, the two ends of the first cross beam 1 and the second ends 32 of the two second cross beams 3 are fixedly connected to the front tower package 200 through one bolt 5; and the two inclined beams 2 are fixedly connected to the front wall structure 300 through two bolts 5. As shown in Figure 1 Figure 4 Figure 9 The front cabin reinforcing structure 100 of the embodiment is connected to the vehicle body through eight bolts 5. Four threaded holes are arranged on the left and right sides, one bolt hole is arranged at each end of the first cross beam 1 and the second end 32 of the two second cross beams 3, and one bolt 5 is arranged for connecting the front tower package 200; four threaded holes are arranged on the rear side, two bolt holes are arranged at the rear ends of the two inclined beams 2, and two bolts 5 are arranged for connecting the front wall structure 300. In this way, the installation point positions are relatively dispersed, the spatial distribution is more uniform and reasonable, the load transmission efficiency can be further improved, and the risk of loose bolts 5 is reduced.

[0066] In addition, only one bolt 5 is arranged at the end of the cross beam in the embodiment, which can avoid the size of the cross beam being too large due to the mounting hole, thereby reducing the weight and cost.

[0067] ​​It can be understood that the bolts 5 of each connection position can also adopt other numbers, for example, the end of the cross beam can also be fixedly connected with the front tower pack 200 through two bolts 5, as long as the installation of the front compartment reinforcing structure 100 can be realized.

[0068] As shown in Figure 4 , the first cross beam 1 includes a straight cross beam section 11 extending in the horizontal direction, the top surface of the straight cross beam section 11 is located in the same horizontal plane as the water channel fastening surface of the front wall structure 300, and the straight cross beam section 11 forms a protruding section; an end arch section 12 connected with the front tower pack 200, the end arch section 12 is connected at both ends of the straight cross beam section 11; wherein, as shown in Figure 8 , the arching height h of the end arch section 12 is 30-70mm; the end arch section 12 includes an inclined arch section and an arc-shaped arch section smoothly connecting the inclined arch section and the straight cross beam section 11, the included angle α between the extension direction of the inclined arch section and the extension direction of the straight cross beam section 11 is 160°-165°; as shown in Figure 9 , the inclined beams 2 are connected with the end of the straight cross beam section 11 and / or the arc-shaped arch section, and the included angle β between the two inclined beams 2 is 70°-90°.

[0069] In this embodiment, the arching height h of the first cross beam 1 is 30-70mm, the bending included angle α is 160°-165°, and the included angle β between the two inclined beams 2 is 70°-90°, which can better transmit force while ensuring the structural rigidity. Of course, the arching height h, the bending included angle α and the included angle β of the inclined beams 2 of the first cross beam 1 can also be adaptively changed according to the actual application scene, and other sizes and angles can be selected.

[0070] The inclined beams 2 are connected with the end of the straight cross beam section 11 and / or the arc-shaped arch section, which is closer to the end connected with the first cross beam 1 and the front tower pack 200, and has better rigidity and strength, which is more conducive to force transmission. Alternatively, the inclined beams 2 can also be connected with the inclined arch section, which is not limited in the present application.

[0071] Preferably, a reinforcing rib 4 extending along the length direction of each beam of the front compartment reinforcing structure 100 is arranged, and the reinforcing rib 4 is arranged in the vertical direction of the vehicle; as shown in Figures 5-7 , a vertical rib penetrating the entire length of each reinforcing beam of the first cross beam 1, the two inclined beams 2 and the two second cross beams 3 is arranged in the middle, which further enhances the rigidity and strength of the reinforcing beam, is conducive to resisting the torsional deformation of the vehicle body, and improves the torsional rigidity of the vehicle body.

[0072] The cross section of each beam of the front compartment reinforcing structure 100 is rectangular, the cross section is large, and the four surfaces of the reinforcing beam are planes, which further improves the rigidity performance of the reinforcing beam, thereby further improving the torsional rigidity of the vehicle body.

[0073] At least one beam of the front compartment reinforcing structure 100 is a variable-thickness beam. Embodiments of the present application design a thickness distribution of the reinforcing beam according to the main transmission path of the front compartment reinforcing structure 100, and different thicknesses are arranged in different areas of the reinforcing beam of the front compartment reinforcing structure 100, the thicknesses are variables, the thickness distribution is determined according to the influence degree of different areas on performance and the process thickness limit of extruded aluminum, and the thicknesses range from 1.5 mm to 5 mm. The area with a large influence on performance is an important area, and the thickness is set to be large, the area with a small influence on performance is an unimportant area, and the thickness is set to be small, so as to ensure that the utilization rate of the material thickness is the highest, and the performance is improved under the condition of the lightest weight.

[0074] Therefore, the front compartment reinforcing structure 100 provided by the embodiments of the present application strengthens the rigidity of the front tower package 200 and the structure of the water channel area, maximizes the improvement of the body torsional rigidity and the mounting point dynamic and static rigidity and other performances in the limited space, and realizes the lightweight structure.
