[0034] An embodiment of the present application provides a front-end body structure, a vehicle body having the front-end body structure, and a vehicle having the front-end body structure. In the front-end body structure, the number of solder joints / weld seams is effectively reduced by a support member with an integral structure. The support member realizes the force transmission and branching with the front longitudinal beam, and can ensure effective force transmission, thereby improving the anti-collision effect. The vehicle body having the front-end body structure and the vehicle having the front-end body structure also have the above advantages. The embodiments of the present application are introduced below with reference to the accompanying drawings of the specification:

[0035] Refer to Figures 1 to 3 , the front-end body structure of the embodiment of the present application includes a front anti-collision assembly 100, a front longitudinal beam 200, and a support member 300. The front anti-collision assembly 100 is used to bear and transmit the collision force backward. Both the front longitudinal beam 200 and the support member 300 are located behind the front anti-collision assembly 100.

[0036] The front end of the front longitudinal beam 200 is connected to the front anti-collision assembly 100, and the front longitudinal beam 200 extends backward. When the front anti-collision assembly 100 is subjected to a collision impact, the front longitudinal beam 200 can bear part of the collision force and transmit it backward.

[0037] The front end of the support member 300 is connected to the front anti-collision assembly 100, and the support member 300 extends backward and upward above the front longitudinal beam 200. When the front anti-collision assembly 100 is subjected to a collision impact, the support member 300 can bear part of the collision force and transmit it backward and upward. The support member 300 is an integrally formed hollow tubular structure, which avoids the tearing and damage of solder joints or weld seams caused by welding. At the same time, it is beneficial to absorb collision energy through deformation. Therefore, the collision force can be conducted smoothly and effectively during the collision process.

[0038] When the front-end body structure is applied to a vehicle, the rear ends of the front longitudinal beam 200 and the support member 300 can be connected to the occupant compartment structure of the vehicle body. The occupant compartment is located behind the occupant compartment structure. Thus, the collision force can be transmitted backward to the occupant compartment structure via the front anti-collision assembly 100 and the front longitudinal beam 200, forming a first force transmission path, and transmitted backward and upward to the occupant compartment structure via the front anti-collision assembly 100 and the support member 300, forming a second force transmission path. Thereby realizing the branched transmission of force, effectively dispersing the collision force, optimizing the force transmission path, and reducing the impact of the collision force on the occupant compartment.

[0039] The support member 300 is an integrally formed hollow tubular structure, which not only simplifies the structure, reduces the number of parts, but also reduces the number of solder joints and weld seams of the front-end body structure, effectively avoiding the tearing and damage of solder joints or weld seams caused by welding, thereby improving the stability of the front-end body structure and the anti-collision effect.

[0040] The support member 300 can be made by integral forming processes such as hydroforming, hot bending forming, and cold bending forming. Without weakening the strength, the wall thickness and weight of the support member 300 can be reduced, the number of solder joints and weld seams distributed on the front-end structure of the vehicle body can be decreased, and the potential safety hazards caused by missing welds and leaking welds can be effectively reduced. The support member 300 can be made to have different bending shapes, cross-sections, dimensions, etc. to suit different vehicle models.

[0041] Reference Figures 1 to 3 , in some embodiments, the support member 300 includes a first section 310, a second section 320, and a third section 330 that are sequentially connected from front to back. The first section 310 is connected to the front anti-collision assembly 100. At least the second section 320 extends backward and upward in a bent manner. The third section 330 is adapted to be connected to the mounting surface 410 on the occupant compartment structure of the vehicle body. Thus, the support member 300 as a whole forms a bent pipe structure. The first section 310 realizes the connection between the support member 300 and the front anti-collision assembly 100, and the third section 330 realizes the connection between the support member 300 and the occupant compartment structure, ensuring the continuity of force transmission. The bent second section 320 is easy to absorb collision energy through deformation.

[0042] Among them, the occupant compartment structure includes the A-pillar and the front panel assembly 400. The occupant compartment is located behind the front panel assembly 400. The two lateral sides of the front panel assembly 400 in the transverse direction are respectively connected to the A-pillar, and the A-pillar extends in the up and down directions to the side structure of the vehicle body.

[0043] In some embodiments, the rear end of the front longitudinal beam 200 can be connected to the A-pillar 500 and the front panel assembly 400. The collision force transmitted backward via the front longitudinal beam 200 can be jointly borne by the A-pillar 500 and the front panel assembly 400, and is transmitted upward and downward through the A-pillar and horizontally left and right through the front panel assembly 400, realizing multi-directional dispersion of the load, which is beneficial to reducing the impact on the occupant compartment.

[0044] In some embodiments, the rear end of the front longitudinal beam 200 can be connected to the A-pillar 500. The collision force transmitted backward via the front longitudinal beam 200 is borne by the A-pillar 500 and is transmitted upward and downward through the A-pillar 500 to disperse the load, which can reduce the deformation of the front panel assembly 400.

[0045] In some embodiments, the rear end of the front longitudinal beam 200 can be connected to the front panel assembly 400. The collision force transmitted backward via the front longitudinal beam 200 is borne by the front panel assembly 400 and is transmitted horizontally left and right, which can reduce the deformation of the A-pillar 500.

[0046] In some embodiments, the third section 330 of the support member 300 can be connected to the A-pillar 500 and the front end assembly 400. For example, on one side of the outer support plates of the A-pillar 500 and the front end assembly 400 facing the third section 330 of the support member 300, there are respectively mounting surfaces 410, and the third section 330 of the support member 300 can be connected to the mounting surfaces 410 of the A-pillar 500 and the front end assembly 400. Therefore, the collision force transmitted backward and upward via the support member 300 can be jointly borne by the A-pillar 500 and the front end assembly 400, and transmitted upward and downward through the A-pillar, and transmitted horizontally to the left and right through the front end assembly 400, realizing multi-directional dispersion of the load, which is beneficial to reducing the impact on the occupant compartment.

[0047] In some embodiments, the third section 330 of the support member 300 can be connected to the A-pillar 500. The collision force transmitted backward and upward via the support member 300 is borne by the A-pillar 500, and transmitted upward and downward through the A-pillar 500 to disperse the load, which can reduce the deformation of the front end assembly 400.

[0048] In some embodiments, the third section 330 of the support member 300 can be connected to the front end assembly 400. The collision force transmitted backward and upward via the support member 300 is borne by the front end assembly 400 and transmitted horizontally to the left and right, which can reduce the deformation of the A-pillar 500.

[0049] Wherein, the second section 320 can also bend and extend outward relative to the front longitudinal beam 200, that is, at least a part of the second section 320 extends outward deviating from the directly upward direction of the front longitudinal beam 200, so as to facilitate the connection of the third section 330 at the rear end to the A-pillar 500, or connect to the outer support plate in the front end assembly 400, and continue to be transmitted backward to body side structures such as the sill, reducing the forward impact on the occupant compartment.

[0050] Reference Figures 4 to 6 , in some embodiments, the front-end structure of the vehicle body further includes a connecting member 340. The first section 310 of the support member 300 extends downward. The side wall of the first section 310 abuts against the rear side surface of the front anti-collision assembly 100. The connecting member 340 is connected to the first section 310 and the front anti-collision assembly 100 to realize the connection between the first section 310 and the front anti-collision assembly 100. The connecting member 340 can enhance the strength of the connection position between the first section 310 and the front anti-collision assembly 100, and improve the stability and reliability of the connection.

[0051] Alternatively, the first section 310 of the support member 300 may not be connected to the front anti-collision assembly 100 through the connecting member 340, but directly connected to the front anti-collision assembly 100 by means of fixed connection such as welding, which can reduce parts and thus reduce the overall weight of the front-end structure.

[0052] The first downward-extending section 310 can be conveniently abutted against the front anti-collision component 100. Compared with the solution of abutting the front anti-collision component through the end part, not only is the connection area larger, the connection is more stable, but also the load-bearing area is larger, avoiding excessive stress concentration and affecting the connection stability, which is beneficial to improving the force transmission effect.

[0053] The side wall of the first section 310 can form an abutting surface parallel to the rear side surface of the front anti-collision component 100, so that the fitting degree can be improved during abutment, and the connection stability is further improved.

[0054] In some embodiments, the first section 310 may include a front side wall 311 and a rear side wall 312 oppositely arranged in the front-rear direction, and two oppositely arranged connecting walls 313 connected between the front side wall 311 and the rear side wall 312. Thus, the front side wall 311, the rear side wall 312 and the connecting walls 313 enclose a square tube structure. The front side wall 311 of the first section 310 forms an abutting surface parallel to the rear side surface of the front anti-collision component 100, and the front side wall 311 abuts against the front anti-collision component 100. The two connecting walls 313 are respectively connected to the front anti-collision component 100 through connecting members 340 to realize the fixation of the first section 310. Moreover, the connecting members 340 are supported between the rear side surface of the front anti-collision component 100 and the connecting walls 313 of the first section 310, and can bear and transmit the collision force of the front anti-collision component 100, which helps to improve the force transmission ability between the first section 310 and the front anti-collision component 100.

[0055] In some embodiments, a detachable connection can be adopted between the first section 310 of the support member 300 and the front anti-collision component 100, so as to facilitate disassembly and assembly, and is convenient for replacement and maintenance. For example, the first section 310 is connected to the front anti-collision component 100 through a connecting member 340, wherein the connecting member 340 is detachably connected to the first section 310, and the connecting member 340 is fixedly connected or detachably connected to the front anti-collision component 100; or, the connecting member 340 is detachably connected to the front anti-collision component 100, and the connecting member 340 is fixedly connected or detachably connected to the first section 310. The above detachable connection can be achieved through structures such as screws and bolts, and the above fixed connection can be achieved through welding, riveting and other methods.

[0056] As an example, the connecting wall 313 of the first section 310 and the connecting member 340 are detachably connected by screws or bolts, and the connecting member 340 and the front anti-collision component 100 are detachably connected by screws or bolts, which can reduce the number of weld points. Moreover, screws and bolts have stronger load-bearing capacity than weld points and rivet points, which can improve the connection stability and reliability.

[0057] In some embodiments, the connecting member 340 includes a first connecting portion and a second connecting portion connected to each other. The second connecting portion defines a receiving groove that is open on the upper, lower, and front three sides. The first connecting portions are respectively connected to the left and right sides of the second connecting portion. The first connecting portion is connected to the front anti-collision assembly 100. The second connecting portion surrounds the outer peripheral side of the first section 310 to accommodate the first section 310 in the receiving groove, and the first section 310 is connected to the second connecting portion.

[0058] In some embodiments, the outer peripheral wall of the third section 330 has a connecting surface 331. The connecting surface 331 is adapted to be parallel to the mounting surface 410. The connecting surface 331 is adapted to abut against the mounting surface 410 on the occupant compartment structure of the vehicle body, ensuring the stability of the connection of the third section 330 and facilitating the improvement of the stability of force transmission. In some embodiments, the third section 330 of the support member 300 may be a square tube structure, and the side wall on the inner side of the third section 330 forms a connecting surface 331 parallel to the mounting surface 410. The third section 330 and the mounting surface 410 can also be connected through the connecting member 340, and the connection method can refer to the way the first section 310 is connected to the front anti-collision assembly 100 through the connecting member 340.

[0059] Alternatively, in some embodiments, along the direction perpendicular to the connecting surface 331, the size of the third section 330 is smaller than that of the second section 320. Thus, the third section 330 forms a relatively flat structure with respect to the second section 320, so that it is convenient to open a through hole penetrating the third section 330 in the direction perpendicular to the connecting surface 331 on the third section 330 for connection through structures such as fasteners. The structure is simple and the connection is stable.

[0060] Reference Figure 1 and Figure 2 In some embodiments, the front longitudinal beam 200 includes an inner longitudinal beam plate 210 and an outer longitudinal beam plate 220. The front end of the inner longitudinal beam plate 210 is connected to the front anti-collision assembly 100, and the inner longitudinal beam plate 210 extends backward. The outer longitudinal beam plate 220 includes a front section 221 and a rear section. The front section 221 is connected to the outside of the inner longitudinal beam plate 210. The rear section includes a first part 222 extending upward, a second part 223 extending downward, and a reinforcing portion 224 connecting between the first part 222 and the second part 223. The reinforcing portion 224 can strengthen the structures of the first part 222 and the second part 223 and improve the load-bearing capacity.

[0061] The outer longitudinal beam plate 220 can adopt an integrally formed structure to optimize the continuity and strength of the structure. The reinforcing portion 224 can be provided with a recessed structure to form the effect of a reinforcing rib, effectively enhancing the strength of the reinforcing portion 224, further ensuring the connection strength between the first part 222 and the second part 223, and reducing the probability of tearing from both sides due to branched force transmission.

[0062] When the front longitudinal beam 200 transmits force backward, while the outer panel 220 of the longitudinal beam transmits the collision force backward, it transmits upward through the first part 222 and downward through the second part 223 in the rear section, thereby realizing the dispersed transmission of force in the rear section. The rear section of the inner panel 210 of the longitudinal beam is suitable for connecting to the front enclosure assembly 400, and the rear section of the outer panel 220 of the longitudinal beam is suitable for connecting to the A-pillar 500. Among them, the second part 223 can transmit the collision force to the A-pillar 500 and the sill. The collision force can be transmitted backward through the front anti-collision assembly 100 and the outer panel 220 of the longitudinal beam to the A-pillar 500 and the sill, forming a third force transmission path, realizing the dispersed transmission of the collision force, and reducing the impact on the occupant compartment.

[0063] In the embodiment of the present application, the front anti-collision assembly 100 may include an anti-collision beam 110 and an energy absorption box 120. The energy absorption box 120 is connected between the anti-collision beam 110 and the front longitudinal beam 200, and the support member 300 is connected to the rear side surface of the energy absorption box 120. When the anti-collision beam 110 is impacted by a collision, the impact force is transmitted backward to the front longitudinal beam 200 and the support member 300 through the energy absorption box 120. During the force transmission process, the energy absorption box 120 can absorb part of the collision energy, thereby reducing part of the collision impact force.

[0064] The vehicle body of the embodiment of the present application includes an occupant compartment structure and the vehicle body front-end structure of the above embodiment, thereby being able to effectively improve the anti-collision effect of the vehicle body.

[0065] Among them, two front longitudinal beams 200 are arranged in the horizontal direction, two support members 300 are arranged in the horizontal direction, the occupant compartment structure is spaced behind the front anti-collision assembly 100, and there is an occupant compartment behind the occupant compartment structure; wherein, the rear end of the front longitudinal beam 200 is connected to the occupant compartment structure, and the rear end of the support member 300 is connected to the occupant compartment structure.

[0066] The occupant compartment structure includes an A-pillar and a front enclosure assembly 400. The front enclosure assembly 400 is spaced behind the front anti-collision assembly 100. Two A-pillars 500 are respectively connected to both sides of the front enclosure assembly 400 in the horizontal direction. The rear end of the front longitudinal beam 200 is connected to the front enclosure assembly 400 and / or the A-pillar 500, and the rear end of the support member 300 is connected to the front enclosure assembly 400 and / or the A-pillar 500. Thus, the occupant compartment is located behind the front enclosure assembly 400. The front enclosure assembly 400, the two front longitudinal beams 200 on both sides, and the front anti-collision assembly 100 enclose the vehicle body front compartment 600, forming a closed-loop structure, strengthening the structural stability and strength of the vehicle body front compartment 600. The shock absorber tower 420 in each side of the front longitudinal beam 200, the support member 300, the A-pillar 500, and the front enclosure assembly 400 also encloses a closed-loop structure, strengthening the stability and strength of the two-side structure. Therefore, during a collision, it ensures the smooth conduction and dispersion of the collision force, and reduces the impact on the occupant compartment.

[0067] The collision force can be transmitted backward through the front longitudinal beam 200 and upward and backward by the support member 300, so as to transmit the collision force to the A-pillar 500 and / or the front bulkhead assembly 400. On the one hand, the branched transmission of the collision force can be realized, the force on the front longitudinal beam 200 can be reduced, and the collision force on the occupant compartment behind the front bulkhead assembly 400 during a frontal impact can be effectively weakened. On the other hand, the arrangement of the support member 300 can reduce the number of solder joints and weld seams, and reduce the probability of tearing damage to the solder joints or weld seams caused by welding. Therefore, effective force transmission can be ensured during the force transmission process, the stability of the vehicle body can be effectively improved, and the anti-collision effect can be improved.
