[0035] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.
[0036] The first embodiment of the utility model provides a vehicle body structure, such as Figure 1-Figure 7 As shown, the vehicle body structure includes a sill beam 1 and a reinforcement component 2 disposed at the front end of the sill beam 1, the reinforcement component 2 includes a first reinforcement plate 21 and a second reinforcement plate 22 that are butted against each other, and a reinforcement cavity is formed between the first reinforcement plate 21 and the second reinforcement plate 22. The reinforcement component 2 is disposed at the front end of the sill beam 1, that is, between the front wheel of the vehicle and an end of the sill beam 1 close to the head of the vehicle. When the front of the vehicle is hit (for example, the front wheel of the vehicle), the reinforcement component is provided to increase the stability of the frontal collision force transmission channel, and the frontal collision force transmission channel is specifically: the front wheel of the vehicle - the reinforcement component 2 - the sill beam 1. When the vehicle is hit head-on, the reinforcement cavity will collapse and deform, thereby improving the energy absorption and collapse capacity of the front of the vehicle during the collision, and improving the impact resistance of the front of the vehicle.
[0037] In some embodiments, as Figure 2 shown, the first reinforcing plate 21 is disposed at the front of the second reinforcing plate 22, and the second reinforcing plate 22 has at least one concave portion with an opening facing the first reinforcing plate 21. Exemplarily, the second reinforcing plate 22 has two concave portions, that is, the first reinforcing plate 21 and the second reinforcing plate 22 are butt-jointed to form a first reinforcing cavity 23 and a second reinforcing cavity 24. The first reinforcing cavity 23 and the second reinforcing cavity 24 are arranged side by side in the vehicle width direction, which can increase the arrangement range of the reinforcing cavities. Further, the first reinforcing plate 21 and the second reinforcing plate 22 are sequentially arranged in the vehicle length direction, so that the reinforcing assembly 2 extends from one end of the sill beam 1 towards the head of the vehicle, making the space between the front wheels of the vehicle and the sill beam 1 more compact. When the front wheels of the vehicle are impacted, it is beneficial to the continuity of the force transmission path of the front wheels of the vehicle - the first reinforcing plate 21 - the second reinforcing plate 22 - the sill beam 1. The impact received by the front wheels of the vehicle is more easily transmitted to the sill beam 1, improving the efficiency of energy transmission and mitigating the impact of the collision.
[0038] In some embodiments, the second reinforcing plate 22 is in a W shape, a serrated shape or a wavy shape, so as to more easily form a reinforcing cavity when the first reinforcing plate 21 and the second reinforcing plate 22 are butt-jointed. Exemplarily, the second reinforcing plate 22 is in a W shape.
[0039] In other embodiments, the first reinforcing plate 21 is a flat plate structure. When the front wheels of the vehicle are impacted and then come into contact with the first reinforcing plate 21, the force on each position of the first reinforcing plate 21 is more uniform. The cross-section of the second reinforcing plate 22 is in an M shape, a "day" shape or a "field" shape, so that the second reinforcing plate 22 is butt-jointed with the first reinforcing plate 21 to form a first reinforcing cavity 23 and a second reinforcing cavity 24. Preferably, the cross-section of the second reinforcing plate 22 is in an M shape. The open side of the second reinforcing plate 22 is butt-jointed with the first reinforcing plate 21, and the platform area (i.e., the boss 221) of the closed side of the second reinforcing plate 22 is connected to the A-pillar 3.
[0040] In some embodiments, through holes are formed in the first reinforcing plate 21, and through holes are also formed in the second reinforcing plate 22. The through holes can be set as weight-reducing holes, and the weight-reducing holes can achieve the lightweight of the reinforcing assembly. The through holes can also be set as vibration-damping holes, and the vibration-damping holes are beneficial to reducing the vibration of the reinforcing assembly.
[0041] In other embodiments, weight-reducing holes or vibration-damping holes are formed in one of the first reinforcing plate 21 and the second reinforcing plate 22. The weight-reducing holes are beneficial to achieving the lightweight of the reinforcing assembly, and the vibration-damping holes are beneficial to reducing the vibration of the reinforcing assembly.
[0042] In some embodiments, the vehicle body structure further includes an A-pillar 3 connected to the front of the sill beam 1. The vehicle A-pillar 3 is close to the front wheel of the vehicle and is an important support for the passenger compartment, the sill beam 1, the instrument assembly, etc. The lower part of the vehicle A-pillar 3 is connected to the front end of the sill beam 1. The vehicle A-pillar 3 includes an A-pillar outer panel 31 and an A-pillar inner panel 32. In a 64 km / h frontal vehicle 25% width rigid barrier collision, the vehicle body longitudinal beam is basically not deformed, while the passenger compartment is deformed more, that is, the deformation of the A-pillar 3 and the sill beam 1 is large, and the connection between the A-pillar inner panel 32 and the A-pillar outer panel 31 is prone to deformation and failure. Specifically, the reinforcement component 2 is arranged at the connection between the A-pillar outer panel 31 and the A-pillar inner panel 32, which can improve the connection strength of the connection between the A-pillar outer panel 31 and the A-pillar inner panel 32. When the front wheel of the vehicle is hit, the connection between the A-pillar outer panel 31 and the A-pillar inner panel 32 is not easy to crack and will not cause the A-pillar 3 to deform and fail, thereby improving the anti-collision performance of the vehicle.
[0043] Specifically, the A-pillar outer panel 31 and the A-pillar inner panel 32 respectively have a connecting flange 34 set toward the head of the vehicle, and the A-pillar outer panel 31 and the A-pillar inner panel 32 are connected through the connecting flange 34. The second reinforcement plate 22 is arranged along the width direction of the vehicle, so that the first reinforcement cavity 23 and the second reinforcement cavity 24 are respectively located on both sides of the connection between the A-pillar outer panel 31 and the A-pillar inner panel 32, which is beneficial to improve the connection strength between the A-pillar outer panel 31 and the A-pillar inner panel 32.
[0044] like Figure 3 As shown, the second reinforcing plate 22 has a boss 221 arranged at intervals on the side facing the door sill beam 1, and the second reinforcing plate 22 is connected to the A-pillar 3 through a second fastener 222, and the second fastener 222 is arranged on the boss 221. The boss 221 is arranged at intervals to reduce the contact area between the second reinforcing plate 22 and the A-pillar inner plate 32 and the A-pillar outer plate 31, thereby preventing the second reinforcing plate 22 from having a large contact surface with the A-pillar inner plate 32 and the A-pillar outer plate 31 and causing corrosion. At the same time, the boss 221 can improve the installation strength of the installation position of the second fastener 222, and improve the connection reliability between the second reinforcing plate 22 and the A-pillar 3.
[0045] In some embodiments, Figure 4 As shown, the A-pillar 3 includes an A-pillar outer plate 31 and an A-pillar inner plate 32 that are butted against each other to form a mounting cavity 33, and at least one mounting bracket 4 is provided in the mounting cavity 33, the mounting bracket 4 is connected to the A-pillar inner plate 32, and the mounting bracket 4 is provided at the lower part of the A-pillar 3. Adding the mounting bracket 4 between the A-pillar inner plate 32 and the A-pillar outer plate 31 can increase the strength of the lower part of the A-pillar 3, prevent the A-pillar 3 and the front wheels of the vehicle from being deformed when the vehicle avoids obstacles, and improve the anti-deformation ability of the A-pillar 3. Exemplarily, two mounting brackets 4 are provided, specifically a first bracket 41 and a second bracket 42.
[0046] The front part of the A-pillar 3 is connected to the wheel arch side beam. A mounting bracket 4 is arranged inside the A-pillar 3 to increase the stability of the force transmission channel on the upper part of the vehicle body when the vehicle is subjected to a head-on collision. Specifically, one of the force transmission channels is: wheel arch side beam - one side of the A-pillar inner panel 32 - the first bracket 41 - the other side of the A-pillar inner panel 32, and the other force transmission channel is: wheel arch side beam - one side of the A-pillar inner panel 32 - the second bracket 42 - the other side of the A-pillar inner panel 32.
[0047] Specifically, Figure 5 and Figure 6 As shown, the first bracket 41 and the second bracket 42 include a reinforcing support plate 411 and a reinforcing connecting plate 412, and the reinforcing support plate 411 is connected to the A-pillar inner plate 32 to improve the support strength of the A-pillar inner plate 32. The reinforcing connecting plate 412 is formed by extending from one side of the reinforcing support plate 411 to the A-pillar outer plate 31, and the reinforcing connecting plate 412 is respectively arranged along the upper and lower sides of the reinforcing support plate 411, so that there are multiple reinforcing connecting plates 412 (two reinforcing connecting plates 412 on both sides of the first bracket 41, and two reinforcing connecting plates 412 on both sides of the second bracket 42) in the installation cavity 33, and the multiple reinforcing connecting plates 412 separate the installation cavity 33 into multiple relatively independent chambers, further improving the energy absorption and collapse capability of the A-pillar 3, and improving the anti-deformation capability of the A-pillar 3. Among them, the two ends of the reinforcing connecting plate 412 are respectively provided with supporting legs 413 connected to the A-pillar inner plate 32, and the two supporting legs 413 are arranged along the length direction of the vehicle, and the provision of the supporting legs 413 is conducive to increasing the lateral support strength of the A-pillar inner plate 32. The extension length of the supporting leg 413 can be adaptively adjusted according to the distance between the reinforcing connecting plate 412 and the A-pillar inner plate 32 .
[0048] In some embodiments, Figure 7 As shown, a hinge reinforcement plate 5 is provided in the A-pillar 3. Specifically, the hinge reinforcement plate 5 is connected to the A-pillar outer plate 31. The hinge reinforcement plate 5 can improve the strength of the hinge at the front door.
[0049] In some embodiments, the vehicle body structure further includes a sill beam reinforcement beam 11 connected to the sill beam 1, and at least one sill beam reinforcement plate 111 is provided in the sill beam reinforcement beam 11 to form a plurality of cavities 112. The sill beam reinforcement beam 11 is provided with a plurality of sill beam reinforcement plates 111, and the sill beam reinforcement plates 111 are provided to improve the structural strength of the sill beam reinforcement beam 11. Specifically, the plurality of sill beam reinforcement plates 111 are arranged crosswise to divide the interior of the sill beam reinforcement beam 11 into a plurality of cavities 112, thereby improving the energy absorption and collapse capability of the sill beam reinforcement beam 11. Exemplarily, the plurality of cavities 112 are arranged in two rows, and three cavities 112 are arranged in each row.
[0050] In some embodiments, the side wall and the bottom of the sill beam reinforcement beam 11 are respectively connected to the sill beam 1. Specifically, the bottom and the side of the sill beam reinforcement beam 11 are respectively connected to the sill beam 1 through the first fastener 12, and the sill beam reinforcement beam 11 and the sill beam 1 are respectively connected from two directions, thereby improving the connection reliability between the sill beam reinforcement beam 11 and the sill beam 1.
[0051] A first reinforcing plate 13 is provided between the sill beam reinforcement beam 11 and the sill beam 1 , and a second reinforcing plate 14 is provided between the sill beam reinforcement beam 11 and the A-pillar outer panel 31 , so as to respectively reinforce the areas with lower strength in the vehicle body structure.
