Description

Technical Field

[0001] The utility model relates to the field of vehicles, in particular to a body assembly for a vehicle and the vehicle. Background Art

[0002] In actual traffic accidents, single-vehicle accidents such as side-slipping and hitting obstacles such as trees and electric poles are common. Obstacles usually have greater rigidity and smaller contact surfaces, resulting in a much greater amount of local intrusion on the side of the vehicle during a collision than a head-on collision, posing a serious threat to the occupants of the vehicle.

[0003] For hydrogen-powered vehicles, the improvement of their safety performance should not only consider the collision safety of the entire vehicle, but also pay special attention to the safety of hydrogen and electricity after the collision. The hydrogen tank of a hydrogen-powered vehicle is usually arranged flatly at the bottom of the vehicle body, which is particularly susceptible to impact and extrusion in a side collision. Especially in the case of a side column collision, the collision point is closer to the battery pack, and the impact and extrusion force on the hydrogen tank is greater, which may cause hydrogen leakage or even fire, further aggravating the degree of harm caused by the accident.

[0004] In the related art, there is a problem of inconsistent force transmission between the door sill beam and the seat crossbeam, which results in the collision energy not being effectively dispersed and absorbed when a side collision occurs, affecting the safety performance of the vehicle. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a body assembly for a vehicle.

[0043] In the related art, there is a problem of inconsistent force transmission between the door sill beam and the seat crossbeam, which results in the collision energy not being effectively dispersed and absorbed when a side collision occurs, affecting the safety performance of the vehicle.

[0044] Reference below Figure 1-Figure 5 A vehicle body structure 1 according to an embodiment of the present invention is described.

[0045] The vehicle body assembly 1 according to the utility model is used for a vehicle, such as Figure 1 and Figure 2As shown, the vehicle body assembly 1 includes a sill beam 11, a reinforcement 12 and a seat cross beam 13, wherein the sill beam 11 extends in the length direction of the vehicle; the reinforcement 12 is arranged at the end of the sill beam 11, and the outer side surface of the reinforcement 12 is connected to the sill beam 11; the seat cross beam 13 is arranged on the inner side of the reinforcement 12 and extends in the width direction of the vehicle; wherein a first reinforcement rib 1211 is formed on the inner side surface of the reinforcement 12, and the first reinforcement rib 1211 is constructed to extend in the length and height directions and intersect with each other, and the first reinforcement rib 1211 forms a plurality of installation areas 1212 on the inner side surface of the reinforcement 12, and a mounting hole 1213 is formed on the reinforcement 12 to cooperate with the sill beam 11, and the mounting hole 1213 is arranged in the mounting area 1212.

[0046] According to the vehicle body assembly 1 of the present invention, the sill beam 11 extends in the length direction of the vehicle. When encountering a collision, the sill beam 11 can effectively absorb and disperse the impact force, reduce the impact force transmitted to the passenger compartment, and thus protect the safety of the passengers.

[0047] The reinforcement 12 is used to connect the surrounding parts into a whole to enhance the rigidity and integrity of the vehicle body. In the event of a collision, the reinforcement 12 can effectively transmit and disperse the impact force from the side, prevent excessive local deformation of the vehicle body, and thus maintain the integrity and spatial stability of the passenger compartment. The reinforcement 12 works in conjunction with the surrounding parts to conduct and disperse the collision energy in a wider area, reducing the stress strength of a single part.

[0048] The seat cross member 13 is disposed inside the reinforcement member 12 and extends in the width direction of the vehicle. The seat cross member 13 not only provides a mounting base for the seat but also enhances the rigidity and stability of the vehicle body in the width direction.

[0049] The inner side surface of the reinforcement 12 is formed with a first reinforcement rib 1211, which extends in the length and height directions and intersects with each other, so that the first reinforcement rib 1211 can conduct and disperse the impact force in different directions. The first reinforcement rib 1211 forms a plurality of installation areas 1212 on the inner side surface of the reinforcement 12, and the installation holes 1213 are arranged in the installation areas 1212. The fasteners are inserted through the installation holes 1213 to connect the reinforcement 12 to the door sill beam 11. By arranging the installation holes 1213 in the installation areas 1212, the installation holes 1213 are separated from the positions of the first reinforcement rib 1211, thereby ensuring the continuity of the first reinforcement rib 1211, so that the first reinforcement rib 1211 can more effectively transmit the impact force to improve the safety performance of the vehicle.

[0050] Therefore, according to the vehicle body assembly 1 of the utility model, by setting the mounting hole 1213 in the mounting area 1212, the continuity of the first reinforcement rib 1211 is ensured, the reinforcement 12 can more effectively conduct and disperse the impact force, the collision energy can be effectively dispersed and absorbed, and the safety performance of the vehicle is improved.

[0051] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the reinforcement 12 includes a first reinforcement portion 121 and a second reinforcement portion 122. The outer side surface of the first reinforcement portion 121 is connected to the sill beam 11, so that the sill beam 11 can effectively transmit the impact force to the reinforcement 12 when encountering a collision, and then disperse it to other parts of the vehicle body through the reinforcement 12. The inner side surface of the first reinforcement portion 121 is provided with a first reinforcement rib 1211, so that the first reinforcement portion 121 can transmit the impact force more efficiently, enhance the structural strength of the first reinforcement portion 121, and can transmit and disperse the impact force in different directions, thereby improving the rigidity and stability of the vehicle body.

[0052] The second reinforcement portion 122 is disposed at the rear end of the first reinforcement portion 121 (i.e., in the rear direction of the vehicle) to be connected to the rear longitudinal beam 14 of the vehicle, which helps to form a continuous reinforcement structure in the longitudinal direction of the vehicle and further improve the overall rigidity of the vehicle body. The second reinforcement portion 122 extends toward the inside of the vehicle in a direction away from the first reinforcement portion 121, so that the reinforcement member 12 forms an effective support structure inside the vehicle, which can better resist the impact force from the side and prevent the vehicle body from being excessively deformed locally during a collision, thereby maintaining the integrity and spatial stability of the passenger compartment.

[0053] According to some embodiments of the utility model, an innovative connection method is adopted between the reinforcement 12 and the threshold beam 11, that is, the use of blind rivets for fastening, which not only ensures the stability of the connection, but also improves the strength of the overall structure. In order to further improve the connection strength, FDS flow drill rivet technology is specially introduced to significantly enhance the shear resistance and fatigue resistance of the connection point.

[0054] According to some embodiments of the present invention, the connection between the reinforcement 12 and the seat cross beam 13 is combined with the use of MIG welding technology and blind rivets, which not only ensures the strength and reliability of the connection, but also optimizes production efficiency and cost control. Specifically, MIG welding provides strong weld strength, while blind rivets provide additional mechanical locking force, and the two complement each other to jointly improve the safety and durability of the structure.

[0055] According to some embodiments of the present invention, Figure 3As shown, a crushing portion 1214 is formed at the top edge of the first reinforcement portion 121. The crushing portion 1214 is used as an energy absorption area when the vehicle collides. When a collision occurs, the crushing portion 1214 will deform to absorb and dissipate the energy generated by the collision, thereby reducing the impact of the collision force on other parts of the vehicle body. The crushing portion 1214 is located at the top edge of the first reinforcement portion 121, that is, above the door sill beam 11 and close to the outside of the vehicle, so that when the vehicle collides from the side, the impact force transmitted to the seat cross beam 13 can be effectively reduced.

[0056] According to some embodiments of the present invention, Figure 2 As shown, a plug-in space open to the rear side is formed on the second reinforcement 122. The plug-in space is not closed, but has an opening to allow other components to be inserted from the rear side and combined with it. The body assembly 1 also includes a rear longitudinal beam 14, which is used to bear the collision force and load from the rear. At least part (front end part) of the rear longitudinal beam 14 is accommodated in the plug-in space and connected to the second reinforcement 122. After the front end part of the rear longitudinal beam 14 is inserted into the plug-in space, it will form a firm connection with the second reinforcement 122. The connection method can be a combination of one or more of welding, bolt connection or other connection methods. The connection between the reinforcement 12 and the rear longitudinal beam 14 not only enhances the rigidity and stability of the vehicle body in the longitudinal direction, but also helps to more evenly distribute the impact force to the entire vehicle body structure during a collision, thereby improving the collision safety performance of the vehicle.

[0057] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second reinforcement part 122 includes an end plate 1221, a side plate 1222 and a bearing plate 1223. The end plate 1221 is connected to the rear end of the first reinforcement part 121, ensuring the structural continuity and stability between the first reinforcement part 121 and the second reinforcement part 122. The side plate 1222 is connected to the end plate 1221 and extends in a direction away from the end plate 1221, so that the side plate 1222 can provide support and positioning for the plug-in space together with the end plate 1221. A second reinforcement rib 1224 is arranged between the outer surface of the side plate 1222 and the end plate 1221. The second reinforcement rib 1224 can withstand the impact force and realize the force conduction between the end plate 1221 and the side plate 1222, thereby increasing the connection strength between the side plate 1222 and the end plate 1221. The bearing plate 1223 is arranged on the inner side of the side plate 1222 and defines the plug-in space between the side plate 1222. The bearing plate 1223 is connected to the bottom surface of the longitudinal beam. The bearing plate 1223 not only provides bottom support for the insertion space, but also enables the rear longitudinal beam 14 to be stably fixed after insertion.

[0058] The end plate 1221 , the side plate 1222 and the load-bearing plate 1223 are in contact with the rear longitudinal beam 14 in different directions respectively, and can be fixedly connected to the rear longitudinal beam 14 respectively, thereby enhancing the connection strength and stability between the rear longitudinal beam 14 and the second reinforcement portion 122 .

[0059] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the end plate 1221 is located at the front end of the rear longitudinal beam 14, directly contacts it and is fixed by welding to ensure the stability of the rear longitudinal beam 14 in the longitudinal direction. The side plate 1222 extends along the side of the rear longitudinal beam 14, forms a contact surface with the side of the rear longitudinal beam 14, and is fixedly connected to the rear longitudinal beam 14 through a corresponding connection structure (such as bolts) to enhance the lateral or oblique support force. The bearing plate 1223, as the bottom support of the plug-in space, directly contacts the bottom surface of the rear longitudinal beam 14. Through welding, bolt connection or other fixing methods, the bearing plate 1223 can ensure the stability of the rear longitudinal beam 14 in the vertical direction and prevent it from displacement or deformation when it is impacted.

[0060] According to some embodiments of the present invention, Figure 2 As shown, the first reinforcing rib 1211 extends to the end plate 1221, so that the impact force borne by the first reinforcing rib 1211 can be transmitted to the end plate 1221, thereby enhancing the structural integrity and strength of the reinforcing member 12. The first reinforcing rib 1211 does not protrude from the edge of the end plate 1221 in the width direction, but remains flush with or retracted from the edge of the end plate 1221, thereby reducing the space occupied by the first reinforcing rib 1211 and reducing the potential conflict between the first reinforcing rib 1211 and other components. When the vehicle collides, the first reinforcing rib 1211 is not easy to squeeze other components and cause damage to other components.

[0061] According to some embodiments of the present invention, Figure 4 As shown, a plurality of structural cavities 111 are formed in the threshold beam 11, which can make the threshold beam 11 have a specific shape under the premise of satisfying the strength of the threshold beam 11, so as to exert the functionality of the threshold beam 11. A reinforcing member 112 is arranged in at least one structural cavity 111 adjacent to the seat cross beam 13, and the reinforcing member 112 is used to increase the strength and rigidity of the threshold beam 11 in a specific area, so that it can better withstand the impact force. By arranging the reinforcing member 112 in the structural cavity 111 adjacent to the seat cross beam 13, the role of the threshold beam 11 in vehicle collision safety is further strengthened, so that when the vehicle is in a side collision, the threshold beam 11 can more effectively absorb and disperse the impact force, reduce the deformation of the threshold beam 11, so that the threshold beam 11 and the seat cross beam 13 maintain a more stable connection, and provide a safer protective barrier for passengers.

[0062] According to some embodiments of the present invention, Figure 1 As shown, the vehicle body assembly 1 also includes a rear crossbeam 15 of the seat, a hydrogen storage device 16 and a rear floor 17. The rear crossbeam 15 of the seat extends in the width direction of the vehicle and is spaced apart from the seat crossbeam 13 in the length direction of the vehicle. The rear crossbeam 15 of the seat and the seat crossbeam 13 together provide a mounting base for the seat. The hydrogen storage device 16 is a device for storing hydrogen and is used in hydrogen fuel cell vehicles. The hydrogen storage device 16 is arranged between the seat crossbeam 13 and the rear crossbeam 15 of the seat, which not only ensures the safety of the hydrogen storage device 16, but also facilitates connection and integration with other systems of the vehicle. The rear floor 17 provides a flat bearing surface for the interior of the vehicle, and is connected between the reinforcement 12, the seat crossbeam 13 and the rear crossbeam 15 of the seat, ensuring the integrity of the vehicle body structure. The rear floor 17 covers the hydrogen storage device 16, effectively isolates the hydrogen storage device 16 from the passenger area, and enables the hydrogen storage device 16 to be better protected, reducing potential safety risks.

[0063] According to some embodiments of the present invention, the connection between the reinforcement 12 and the rear floor 17 adopts SPR (self-piercing riveting) rivet technology, which can produce high-efficiency, low-energy consumption and high-quality connection effects. SPR rivets achieve self-locking through plastic deformation of materials, without the need for additional welding materials or heat sources, which not only ensures the connection strength but also simplifies the production process.

[0064] According to some embodiments of the present invention, Figure 5 As shown, the rear cross beam 15 of the seat includes a plurality of structural members 151 connected to each other, which provides higher flexibility and adaptability, and allows the shape and strength of the rear cross beam 15 of the seat to be customized according to the specific needs and spatial layout of the vehicle. The angle formed between the extension directions of at least two adjacent structural members 151 is an acute angle, that is, the extension directions of at least two adjacent structural members 151 are not completely parallel or vertical. The existence of the acute angle makes the rear cross beam 15 of the seat have higher stability. When the rear cross beam 15 of the seat is subjected to lateral force, it can more effectively disperse and resist the lateral force, thereby improving the overall structural strength of the rear cross beam 15 of the seat.

[0065] According to some embodiments of the present invention, Figure 5 As shown, there are three adjacent structural members 151 forming a closed triangle. When the three structural members 151 form a triangle, the stability principle of the triangle can be used to significantly enhance the overall rigidity and anti-deformation ability of the rear cross beam 15 of the seat. The three corners of the triangle serve as support points, which can evenly disperse and resist forces from all directions, so that the rear cross beam 15 of the seat can maintain better stability when impacted.
