[0002] With the rapid development of the automobile industry and the increasing demand of consumers for vehicle safety performance, the safety design of the body structure has become the focus of automobile manufacturers. As an important part of the body, the body threshold structure can resist the force when the vehicle collides, especially when it hits the side, and effectively transmit the force of the collision to protect the structure of the passenger compartment and avoid injuries to the driver and passengers in the car. Therefore, the structural strength of the body threshold structure is related to the overall safety of the vehicle.

[0003] At present, the existing body rocker structures are mostly made of steel plate stamping parts. Although their structural form meets the basic load-bearing requirements of the vehicle body to a certain extent, in the event of a high-intensity collision of the vehicle, the structural strength of the existing body rocker structure is limited and it is easy to be severely deformed due to the collision, causing the body rocker structure to invade the passenger compartment and endanger the safety of the occupants, thereby resulting in poor safety of the vehicle. Utility Model Content

[0004] In view of this, the utility model aims to provide a vehicle body sill structure to improve the structural strength of the sill structure, thereby enhancing the safety of the vehicle.

[0013] Furthermore, a blocking plate is provided at the front end and / or the rear end of the reinforcing plate, and the blocking plate is formed by welding a plurality of connecting flanges at the end portions of the reinforcing plate.

[0014] Furthermore, the first reinforcement member and the second reinforcement member are located below the B-pillar in the vehicle body.

[0015] Furthermore, the B-pillar has a lower inner panel of the B-pillar, and the bottom of the lower inner panel of the B-pillar is provided with a lap portion extending into the sill beam cavity; the lap portion is located between the first reinforcement and the second reinforcement, and the sill beam cavity is divided into left and right parts by the lap portion.

[0016] Furthermore, a weight-reducing hole is provided on the overlapping portion.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] The vehicle body sill structure described in the utility model, through the arrangement of the first reinforcement member and the second reinforcement member, utilizes the characteristics of the "J"-shaped structure with good bending resistance and torsional resistance to reinforce the side panels and the sill beam. At the same time, the relative arrangement of the first reinforcement member and the second reinforcement member in the direction of the vehicle can improve the overall bending resistance and torsional resistance of the sill structure, thereby improving the structural strength of the sill structure and improving the ability of the sill structure to resist external force impacts, thereby improving the safety of the vehicle.

[0019] In addition, the first reinforcement and the second reinforcement are arranged at intervals, and a third I-shaped cavity is formed between the first reinforcement and the second reinforcement, which optimizes the cross-sectional shape of the body rocker structure, improves the bending resistance and load-bearing capacity of the body rocker structure, and thus improves the structural strength of the body rocker structure.

[0022] In addition, the B-pillar has a lower inner plate, and the overlapped portion at the bottom of the lower inner plate of the B-pillar is arranged in the door sill beam cavity and between the first reinforcement and the second reinforcement, which can better disperse the force on the B-pillar to the vehicle body door sill structure, optimize the cross-sectional shape of the door sill beam, further improve the bending and torsion resistance of the vehicle body door sill structure, and enhance the structural strength of the vehicle body door sill structure.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] Embodiment 1

[0046] This embodiment relates to a vehicle body door sill structure, the overall structure of which is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the vehicle body rocker structure includes a rocker beam 1 , a side panel 2 , a first reinforcement member 3 and a second reinforcement member 4 .

[0047] The sill beam 1 and the side panel 2 are buckled and connected together in the left-right direction of the vehicle, and a sill beam 1 cavity is formed between the sill beam 1 and the side panel 2. The sill beam 1 cavity is provided with a first reinforcement member 3 connected to the sill beam 1 and a second reinforcement member 4 connected to the side panel 2. The first reinforcement member 3 and the second reinforcement member 4 are both in a "J"-shaped structure, and the first reinforcement member 3 and the sill beam 1 enclose a first cavity 301, and the second reinforcement member 4 and the side panel 2 enclose a second cavity 401, and the first reinforcement member 3 and the second reinforcement member 4 are arranged relatively in the left-right direction of the vehicle.

[0048] At this time, as set above, through the arrangement of the first reinforcement 3 and the second reinforcement 4, this embodiment can utilize the characteristics of the "J"-shaped structure with good bending and torsional resistance to reinforce the side panel 2 and the sill beam 1. At the same time, the relative arrangement of the first reinforcement 3 and the second reinforcement 4 in the direction of the vehicle can improve the overall bending and torsional resistance of the sill structure, so as to improve the structural strength of the sill structure, thereby achieving the effect of improving the ability of the sill structure to resist external force impact and improving the safety of the vehicle.

[0049] Based on the above overall introduction, specifically, the side panel 2 and the sill beam 1 of this embodiment are both in a "J"-shaped structure, and the flanges at the upper and lower ends of the side panel 2 and the sill beam 1 are connected together, which increases the connection area between the side panel 2 and the sill beam 1, and increases the connection strength between the side panel 2 and the sill beam 1, thereby increasing the structural strength of the vehicle body sill structure as a whole and ensuring the safety of the vehicle. In specific implementation, the side panel 2 and the sill beam 1 of this embodiment can be connected by conventional connection methods known to those skilled in the art, such as welding, riveting, screwing, etc., as long as the connection strength between the side panel 2 and the sill beam 1 is guaranteed.

[0050] In order to further improve the structural strength of the vehicle body rocker structure of this embodiment, as Figure 3 As shown, the first reinforcement 3 and the second reinforcement 4 of this embodiment are arranged at intervals in the left-right direction of the vehicle, and a third cavity 5 in the shape of an "I" is formed between the first reinforcement 3 and the second reinforcement 4. By setting the third cavity 5 in the shape of an "I", the cross-sectional shape of the vehicle body rocker structure is optimized, so that the upper and lower ends of the vehicle body rocker structure can withstand greater bending moments to improve the bending resistance of the vehicle body rocker structure. At the same time, the middle part of the third cavity 5, that is, the first reinforcement 3 and the second reinforcement 4, mainly withstands shear force and has a good bearing capacity, thereby improving the structural strength of the vehicle body rocker structure.

[0051] In addition, the third cavity 5 in the shape of an “I” can better disperse and dissipate the force, thereby improving the ability of the vehicle body sill structure to resist external force impact. When the side panel 2 is impacted by external force in the left and right directions of the vehicle, the distance between the first reinforcement 3 and the second reinforcement 4 can provide a certain collapse buffer space for the side panel 2, thereby dissipating part of the force through the collapse of the side panel 2.

[0052] In order to improve the structural strength of the first reinforcement member 3, as Figure 2 , Figure 3 and Figure 5As shown, in order to improve the effect of the first reinforcement member 3 reinforcing the door sill structure, a support frame 302 connected to the first reinforcement member 3 is provided in the first cavity 301 of this embodiment. And the support frame 302 is in a "J"-shaped structure, and forms a first cavity with the first reinforcement member 3. It can be understood that the support frame 302 and the first reinforcement member 3 form a first cavity, which can support the first reinforcement member 3 in the left and right directions of the whole vehicle. Prevent the first reinforcement member 3 from collapsing due to external force when the vehicle is hit from the side, resulting in a decrease in the reinforcement effect on the door sill beam 1, which can easily cause the vehicle body door sill structure to invade the passenger compartment, affecting the safety of the vehicle. At the same time, the support frame 302 is in a "J"-shaped structure, has good structural strength, and can also support the first reinforcement member 3 in the height direction of the whole vehicle, improve the bending resistance of the first reinforcement member 3 and the door sill beam 1, and thus improve the bearing capacity of the door sill beam 1.

[0053] In specific implementation, the flange formed on the support frame 302 of this embodiment is connected to the inner wall of the upper and lower ends and the side of the first reinforcement member 3, and the connection area with the first reinforcement member 3 is large, and the connection effect is good. In addition, the support frame 302 of this embodiment can be configured as one or multiple ones arranged at intervals along the length direction of the first reinforcement member 3, as long as the reinforcement effect of the support frame 302 on the first reinforcement member 3 can be guaranteed.

[0054] In order to improve the protection effect of the body sill structure on the passenger compartment and enhance the safety of the vehicle, such as Figure 1 , Figure 2 and Figure 3 As shown, the side panel 2 of this embodiment includes a side panel reinforcement plate 201 and a side panel outer panel 202 located outside the side panel reinforcement plate 201. The second reinforcement member 4 is connected to the side panel reinforcement plate 201, and a second cavity 203 is formed between the side panel outer panel 202 and the side panel reinforcement plate 201. The second cavity 203 formed by the side panel reinforcement plate 201 and the side panel outer panel 202 can provide a certain collapse space for the side panel outer panel 202 when the vehicle is hit from the side, so that the side panel outer panel 202 can collapse toward the second cavity 203 due to the external force, and play the role of energy absorption and buffering, thereby improving the protection effect of the vehicle body sill structure on the passenger compartment, and further improving the safety of the vehicle.

[0055] In addition, the provision of the second cavity 203 can optimize the cross-sectional shape of the side panel 2 , can better disperse and eliminate the force, and improve the overall bending and torsional resistance of the side panel 2 , thereby improving the overall structural strength of the side panel 2 .

[0056] In order to further improve the structural strength of the threshold beam 1, Figure 2 , Figure 3 and Figure 4As shown, a reinforcing plate 6 connected to the sill beam 1 is provided in the cavity of the sill beam 1 of the present embodiment. The reinforcing plate 6 extends along the front-rear direction of the vehicle, and the cross section of the reinforcing plate 6 is a "U"-shaped structure with the opening facing the side of the side panel 2, and the first reinforcing member 3 is located in the reinforcing plate 6. The sill beam 1 can be reinforced by providing the "U"-shaped reinforcing plate 6, and the upper and lower ends of the reinforcing plate 6 can support the sill beam 1 in the height direction of the vehicle, thereby improving the structural strength of the sill beam 1.

[0057] Specifically, Figure 6 As shown, the upper and lower ends of the reinforcing plate 6 of this embodiment are respectively formed with transversely extending end plates 601 to form a "U"-shaped structure. The two end plates 601 support the sill beam 1 in the height direction of the whole vehicle.

[0058] In order to improve the structural strength of the reinforcing plate 6 and enhance the reinforcing effect of the reinforcing plate 6 on the threshold beam 1, continue to combine Figure 6 As shown, one or both of the front end and the rear end of the reinforcing plate 6 of this embodiment are provided with a plugging plate 602, and the plugging plate 602 is formed by welding a plurality of connecting flanges at the ends of the reinforcing plate 6. The connecting flanges include a first connecting flange 6021 formed on the two end plates 601, and a second connecting flange 6022 formed on the vertical portion of the reinforcing plate 6. Through the plugging plate 602 formed by welding a plurality of connecting flanges, the plugging plate 602 can support the two end plates 601, that is, the reinforcing plate 6, in the height direction of the whole vehicle, thereby improving the structural strength of the reinforcing plate 6 and enhancing the reinforcing effect on the door sill beam 1. In addition, the connecting flanges are welded to form the plugging plate 602, which facilitates the processing and forming of the reinforcing plate 6 to a certain extent, so that the reinforcing plate 6 can be formed by bending a plate.

[0059] In the specific implementation, as a preferred implementation mode, blocking plates 602 are provided at both ends of the reinforcing plate 6 of this embodiment, so that the two blocking plates 602 can form supports at both ends of the reinforcing plate 6, thereby ensuring the structural stability of the reinforcing plate 6, and further improving the structural strength of the reinforcing plate 6 and the reinforcing effect on the threshold beam 1.

[0060] In this embodiment, the body rocker structure is the bottom structure of the body and carries other body structures. Taking the junction of the B-pillar in the body and the body rocker structure as an example, the body rocker structure needs to have a better bearing capacity to ensure the stability of the support for the B-pillar. Therefore, in order to improve the bearing capacity of the body rocker structure, the first reinforcement member 3 and the second reinforcement member 4 of this embodiment are located below the B-pillar in the body.

[0061] It can be understood that since the B-pillar is supported by the body rocker structure, the junction of the body rocker structure and the B-pillar is subjected to a relatively large force in the height direction of the entire vehicle. Therefore, locating the first reinforcement 3 and the second reinforcement 4 below the B-pillar can structurally reinforce the junction between the body rocker structure and the B-pillar, improve the bending resistance of the junction, and further improve the bearing capacity of the body rocker structure, thereby ensuring the bearing effect of the body rocker structure on the B-pillar and other body structures.

[0062] In specific implementation, the reinforcing plate 6 of this embodiment is also located below the B-pillar to reinforce the vehicle body rocker structure. At the same time, at least part of the reinforcing plate 6 can be located directly below the B-pillar, while the rest of the reinforcing plate 6 is located in the part of the rocker beam 1 adjacent to the B-pillar. Thus, the reinforcing plate 6 can withstand the bending moment and shear force generated by the bearing of the B-pillar, and can further improve the reinforcing effect of the reinforcing plate 6 on the vehicle body rocker structure to a certain extent, thereby improving the bearing capacity of the vehicle body rocker structure.

[0063] In addition, the first reinforcement 3 and the second reinforcement 4 of this embodiment can also be arranged at other positions, such as below the C-pillar in the vehicle body, so as to structurally reinforce the weak positions of the vehicle body rocker structure that support other vehicle body structures.

[0064] In this embodiment, the B-pillar has a lower inner plate 7 of the B-pillar, and the bottom of the lower inner plate 7 of the B-pillar is provided with a lap joint 701 extending into the cavity of the sill beam 1. The lap joint 701 is located between the first reinforcement 3 and the second reinforcement 4, and the cavity of the sill beam 1 is divided into left and right parts by the lap joint 701. It can be understood that the lap joint 701 is set between the side panel 2 and the sill beam 1, and is connected to the upper and lower ends of the side panel 2 and the sill beam 1 to divide the sill beam 1 into left and right parts. The lap joint 701 can better disperse the force on the B-pillar to the vehicle body sill structure, thereby improving the bearing effect of the vehicle body sill structure on the B-pillar. In addition, the setting of the lap joint 701 optimizes the cross-sectional shape of the sill beam 1, further improves the bending and torsion resistance of the vehicle body sill structure, and improves the structural strength of the vehicle body sill structure.

[0065] In addition, a weight-reducing hole 702 is also provided on the overlap portion 701 of this embodiment, and the shock-absorbing hole can reduce the weight of the lower inner plate 7 of the B-pillar, thereby ensuring the lightweight of the vehicle body rocker structure. In specific implementation, the weight-reducing hole 702 is rectangular and is configured as two horizontally arranged holes, which reduces the weight of the overlap portion 701 while ensuring the structural strength of the overlap portion 701, thereby achieving the effect of lightweighting the vehicle body rocker structure.

[0066] In summary, the vehicle body sill structure of the present embodiment, through the arrangement of the first reinforcement 3 and the second reinforcement 4, utilizes the characteristics of the "J"-shaped structure with good bending and torsional resistance to reinforce the side panel 2 and the sill beam 1. At the same time, the relative arrangement of the first reinforcement 3 and the second reinforcement 4 in the vehicle direction can improve the overall bending and torsional resistance of the sill structure, thereby improving the structural strength of the sill structure and improving the ability of the sill structure to resist external force impact, thereby improving the safety of the vehicle.
