[0002] As people pay more and more attention to vehicle collision safety, the collision response capability of the vehicle body structure becomes more and more important. Taking the side collision of a vehicle as an example, the door sill position is the main contact point when the vehicle hits the side, and most of the side collision force needs to be absorbed and transmitted through the door sill of the vehicle body.

[0003] At present, in order to increase the rigidity of the vehicle body sill beam, a reinforcement beam is usually set inside the sill beam, and the reinforcement beam is generally set on the inner wall of one side of the sill beam. Although this setting method can enable the reinforcement beam to participate in the absorption and transmission of side impact energy, it is limited by the setting form of the reinforcement beam inside the sill beam, which will also affect the degree of participation of the reinforcement beam in side impact, and is not conducive to improving the side impact safety of the whole vehicle.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0046] Embodiment 1

[0047] This embodiment relates to a vehicle body door sill assembly, combined with Figures 1 to 3 As shown in , the vehicle body rocker assembly includes a rocker beam body 100 and a reinforcing beam 4 located in the rocker beam body 100 .

[0048] The sill beam body 100 includes a side sill 1 and a floor sill 2 that are snap-fitted together, the reinforcing beam 4 extends along the length direction of the sill beam body 100 , and the side of the reinforcing beam 4 close to the side sill 1 is connected to the side sill 1 , and the side of the reinforcing beam 4 close to the floor sill 2 is connected to the floor sill 2 .

[0049] At this time, as set above, by connecting the side of the reinforcing beam 4 close to the side door sill 1 to the side door sill 1, and connecting the side of the reinforcing beam 4 close to the floor door sill 2 to the floor door sill 2, the present embodiment can utilize the connection between the reinforcing beam 4 and the side door sills 1 and the floor door sill 2 on both sides, thereby increasing the stability of the reinforcing beam 4 set in the door sill beam body 100, and being able to increase the absorption and transmission capacity of the side collision force in the event of a side collision.

[0050] Based on the above overall introduction, specifically, in the vehicle body and along the left and right direction of the vehicle, the side sill 1 is located on the side of the sill beam body 100 facing the outside of the vehicle, and the floor sill 2 is located on the side of the sill beam body 100 facing the inside of the vehicle, and the floor sill 2 is generally also connected to the front floor 3.

[0051] In this embodiment, as a preferred implementation form, continue to combine Figure 4 As shown in the figure, a reinforcing beam connecting plate 5 is provided on the side door sill 1, and the reinforcing beam 4 is connected to the reinforcing beam connecting plate 5. At this time, it can be understood that the reinforcing beam 4 is connected to the side door sill 1 through the reinforcing beam connecting plate 5, which can facilitate the connection between the reinforcing beam 4 and the side door sill 1.

[0052] In addition, Figure 4 As shown, preferably, in a specific implementation, the above-mentioned reinforcing beam connecting plate 5 can be set as a plurality of reinforcing beam connecting plates 5 arranged at intervals along the length direction of the reinforcing beam 4. In this way, the reinforcing beam connecting plates 5 are arranged at intervals, and multi-point connection can be achieved by setting a plurality of reinforcing connecting plates 5, thereby ensuring the reliability of the connection between the reinforcing beam 4 and the side sill 1.

[0053] In addition, continue as Figure 5 As shown in the figure, as a preferred exemplary structural form, the reinforcing beam connecting plate 5 of this embodiment can be prepared by stamping, and can be in the shape of a "J", for example, and has a connecting boss 5a protruding toward one side of the reinforcing beam 4, and connecting arms 5b located on both sides of the connecting boss 5a. The reinforcing beam 4 is connected to the connecting boss 5a, and the connecting arms 5b on both sides are connected to the side sill 1.

[0054] At this time, by making the reinforcing beam connecting plate 5 into a "J" shape, it is obvious that it can take advantage of the high strength of the "J"-shaped structure to increase the structural strength of the reinforcing beam connecting plate 5 itself. At the same time, based on the connection boss 5a protruding toward the reinforcing beam 4 relative to the connecting arms 5b on both sides, it can also facilitate the connection between the reinforcing beam connecting plate 5 and the side door sill 1 and the reinforcing beam 4.

[0055] In this embodiment, the reinforcing beam connecting plate 5 can generally be fixedly connected to the side door sill 1 by welding, that is, the connecting arms 5b on both sides can be connected to the side door sill 1 by electric welding. In this way, by welding the reinforcing beam connecting plate 5 to the side door sill 1, the connection setting of the reinforcing beam connecting plate 5 on the side door sill 1 can be facilitated, and the stability of the connection can also be ensured.

[0056] In this embodiment, for the connection between the reinforcing beam 4 and the reinforcing beam connecting plate 5, preferably, the reinforcing beam 4 can be connected to the reinforcing beam connecting plate 5 through a screw connection structure. In this way, the reinforcing beam 4 is connected to the reinforcing beam connecting plate 5 through a screw connection structure, which not only has a simple structure and convenient connection, but also can ensure the reliability of the connection.

[0057] In a specific implementation, the screw connection structure for connecting the reinforcing beam 4 and the reinforcing beam connecting plate 5 may include, for example, a threaded connection hole provided on the reinforcing beam connecting plate 5 or a projection welding nut fixedly connected to the reinforcing beam connecting plate 5, and also includes a connecting bolt passing through the reinforcing beam 4. In addition, in order to perform the connecting operation of the connecting bolt, the connecting bolt is connected to the reinforcing beam 4 by a screw threaded hole provided on the reinforcing beam connecting plate 5. Figure 7 As shown in , a mounting hole 4b may be provided on the reinforcing beam 4, and the above-mentioned connecting bolts may be connected via the mounting hole 4b.

[0058] It should be noted that, in the present embodiment, in addition to making the reinforcing beam connecting plate 5 adopt a "J"-shaped structure, it is of course also possible to make it adopt other conventional structural forms such as a "kou"-shaped or "eye"-shaped structure, as long as it can achieve a stable connection between the reinforcing beam 4 and the side door sill 1.

[0059] In this embodiment, as a preferred implementation form, combined with Figure 6 As shown, a protrusion 2a protruding toward one side of the reinforcing beam 4 is provided on the floor sill 2, and the reinforcing beam 4 is specifically connected to the protrusion 2a, and through the connection with the protrusion 2a, a gap s is formed between the reinforcing beam 4 and the floor sill 2.

[0060] At this time, by providing the raised portion 2a on the floor sill 2, the reinforcing beam 4 is connected to the raised portion 2a and a gap s is formed between the reinforcing beam 4 and the floor sill 2, which can prevent the reinforcing beam 4 from flipping over due to its own weight during a side collision, and can balance the force on the reinforcing beam 4 to ensure its effect of absorbing and transmitting the collision force. At the same time, a gap s is formed between the reinforcing beam 4 and the floor sill 2, which forms a collapse space between the two, and the gap s formed can also be used to better absorb the side collision energy.

[0061] In the specific implementation of this embodiment, Figure 6 As shown, preferably, the raised portion 2a can be integrally formed on the floor sill 2 by, for example, stamping. This allows the raised portion 2a to be integrally formed on the floor sill 2, which can facilitate the preparation of the raised portion 2a and ensure the structural strength of the raised portion 2a.

[0062] In addition, the above-mentioned raised portion 2a can also be preferably provided as a plurality of raised portions 2a arranged at intervals along the length direction of the reinforcing beam 4. In this way, by providing a plurality of raised portions 2a arranged at intervals, the reliability of the connection between the reinforcing beam 4 and the floor sill 2 can also be ensured through multi-point connection.

[0063] In addition, in the present embodiment, preferably, the reinforcing beam 4 and the raised portion 2a may be connected, for example, by a screw connection structure, so as to achieve the advantages of simple structure, convenient connection, and ensuring the reliability of the connection between the two.

[0064] In specific implementation, the screw connection structure between the reinforcing beam 4 and the raised portion 2a, that is, between the reinforcing beam 4 and the floor sill 2, may include, for example, a threaded connection hole or a projection welding nut provided on the reinforcing beam 4, and a connection bolt passed through the connection hole on the projection 2a. When the vehicle is assembled, after the side sill 1 connected to the reinforcing beam 4 is buckled onto the floor sill 2, a connection bolt is passed through the outer side of the floor sill 2, that is, below the front floor 3, and fixedly connected to the threaded connection hole or projection welding nut on the reinforcing beam 4.

[0065] It should be noted that, in addition to providing threaded connection holes or projection welding nuts on the reinforcing beam 4, it is also possible to provide projection welding bolts on the reinforcing beam 4, and correspondingly, when the whole vehicle is assembled, the projection welding bolts are passed through the connection holes at the raised portion 2a and then connected to the outer side of the floor sill 2 through nuts. Moreover, it is understandable that the reinforcing beam 4 and the reinforcing beam connecting plate 5, as well as the reinforcing beam 4 and the raised portion 2a are connected by a screw connection structure, which can also facilitate the later maintenance and replacement of the reinforcing beam 4 or the side sill and the floor sill 2, so as to reduce the maintenance cost.

[0066] In this embodiment, Figure 2 as well as Figure 6 , Figure 7 As shown in the figure, as a preferred embodiment, the side where the above-mentioned raised portion 2a is connected to the reinforcing beam 4 has a connecting slope 2b, which gradually slopes downward in the direction pointing to one side of the reinforcing beam 4, and when the reinforcing beam 4 is connected to the raised portion 2a, the reinforcing beam 4 also abuts against the connecting slope 2b through the matching slope 4a on itself.

[0067] At this time, by making the protrusion 2a and the reinforcing beam 4 abut against each other through the matching connection bevel 2b and the matching bevel 4a, the reinforcing beam 4 can be better supported on the basis of the setting of the protrusion 2a, so as to prevent the reinforcing beam 4 from turning over and affecting the setting effect of the reinforcing beam 4. In specific implementation, the inclination angle of the above-mentioned connection bevel 2b can be set according to the specifications and dimensions of the reinforcing beam 4, as long as it can form a supporting force for the reinforcing beam 4 pointing obliquely upward.

[0068] In this embodiment, still refer to Figure 7 As shown, as a preferred implementation form, the reinforcing beam 4 can be made of extruded aluminum profiles, for example. In this way, the reinforcing beam 4 is made of extruded aluminum profiles, which can facilitate its preparation, and can also ensure the structural strength of the reinforcing beam 4, and is conducive to the lightweight of the reinforcing beam 4. However, in addition to the extruded aluminum profiles, of course, in the specific implementation, the reinforcing beam 4 of this embodiment can be made of a beam structure such as a tube beam or other structural forms, which is also feasible, as long as it can meet the reinforcement effect of the door sill position of the vehicle body.

[0069] The vehicle body sill assembly of the present embodiment adopts the above structure. By connecting the reinforcing beam 4 with the side sill 1 and the floor sill 2, the stability of the reinforcing beam 4 arranged in the sill beam body 100 can be increased, and the absorption and transmission capacity of the side collision force can be increased during a side collision, which is beneficial to improving the safety of the entire vehicle in a side collision.

[0070] Embodiment 2

[0072] Among them, combined Figure 8 and Fig. 9 As shown, in the vehicle body of this embodiment, the above-mentioned vehicle body door sill assembly can generally be used only on the main driver's side. However, in addition to being set on the main driver's side, of course, based on the vehicle model design requirements, it is also possible to set the above-mentioned vehicle body door sill assembly on both the left and right sides.

[0073] In addition, as a preferred implementation form, the vehicle body of this embodiment is also provided with a front floor cross beam 7 located below the front floor 3. The front floor cross beam 7 and the seat cross beam 6 located above the front floor 3 are arranged correspondingly up and down. At the same time, the front floor cross beam 7 can also form a force transmission channel arranged along the left and right direction of the vehicle between the vehicle body door sill assemblies on both sides.

[0074] In this way, by arranging the front floor cross beam 7 under the front floor 3, the front floor cross beam 7 and the seat cross beam 6 are arranged correspondingly up and down, and the front floor cross beam 7 can form a force transmission channel between the door sills on both sides. In this embodiment, the front floor cross beam 7 is combined with the seat cross beam 6 to increase the lateral (i.e., left and right direction of the whole vehicle) transmission capacity of the side collision force, which helps to disperse and eliminate the collision force, and can further improve the side collision safety.

[0075] Specifically, in the vehicle body of this embodiment, the seat cross beams 6 are usually arranged in two spaced apart arrangement along the front-rear direction of the vehicle, and the lower front floor cross beams 7 are arranged to match the number and position of the seat cross beams 6. At the same time, for the force transmission channel formed above, in specific implementation, for example, the left and right ends of the front floor cross beam 7 can be directly connected to the door sill positions on both sides, or, as in Fig. 9 As shown in , in this embodiment, front floor longitudinal beams 9 arranged on the left and right sides can also be arranged under the front floor 3, the front floor cross beam 7 is located between the front floor longitudinal beams 9 on both sides, and a connecting beam 8 is arranged corresponding to the front floor cross beam 7, so that the connected front floor cross beam 7, the front floor longitudinal beam 9 and the connecting beam 8 together form a lateral force transmission channel located between the vehicle body door sills on both sides.

[0076] The vehicle of this embodiment is provided with the body door sill assembly of the first embodiment, and can increase the stability of the setting of the reinforcing beam 4 while providing the reinforcing beam 4. At the same time, the lateral force transmission channel formed by the reinforcing beam 4 and the above-mentioned front floor cross beam 7 can also increase the absorption and transmission capacity of the side collision force during a side collision, thereby helping to improve the safety of the whole vehicle in a side collision.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
