As shown in fig. 1 to 5, along the width direction of the vehicle, a sealing member is required to be arranged at the joint of the chassis floor 1 and the threshold beam 2 to seal the gap between the chassis floor 1 and the threshold beam 2, so that the tightness of the joint of the chassis floor 1 and the threshold beam 2 is ensured, small particle objects such as sand and stone are prevented from being clamped at the joint of the chassis floor 1 and the threshold beam 2, the NVH performance (Noise, vibration, harshness, noise, vibration and harshness) of the vehicle is improved, or the leakage of the joint of the chassis floor 1 and the threshold beam 2 is avoided.

The sealing member may be configured as a sealant or a sealing strip, in some embodiments, the sealing member is configured as a sealant, in the process of vehicle production and manufacturing, the gluing device is used for gluing the joint of the chassis floor 1 and the threshold beam 2, the sealant is used for sealing the gap between the chassis floor 1 and the threshold beam 2, one end of the supporting beam 4 is fixedly connected with the corresponding mounting longitudinal beam 3, the other end of the supporting beam 4 is spaced from the corresponding threshold beam 2, so that the situation that the supporting beam 4 breaks the joint of the chassis floor 1 and the threshold beam 2 in the length direction of the vehicle is avoided, and the continuity of the sealant is ensured in the process of gluing the joint of the chassis floor 1 and the threshold beam 2 by the gluing device, thereby improving the tightness of the joint of the chassis floor 1 and the threshold beam 2.

Therefore, one end of the supporting cross beam 4 is fixedly connected with the corresponding mounting longitudinal beam 3, and the other end of the supporting cross beam 4 is spaced from the corresponding threshold beam 2, so that the vehicle body structure 100 according to the embodiment of the utility model can meet the structural strength requirement, can ensure the tightness of the joint of the chassis floor 1 and the threshold beam 2, has better NVH performance, and can avoid the risk of liquid leakage at the joint of the chassis floor 1 and the threshold beam 2.

In some embodiments of the present utility model, as shown in fig. 4, a plurality of support cross members 4 are provided between the installation stringers 3 and the respective rocker beams 2, which are arranged in the longitudinal direction of the vehicle, and the structural strength of the vehicle body structure 100 is further improved by providing a plurality of support cross members 4. In some embodiments, two adjacent support beams 4 arranged along the length direction of the vehicle may be disposed at intervals or connected to each other, and it should be noted that the arrangement form of the two adjacent support beams 4 may be specifically arranged according to the design requirement of the vehicle body structure 100.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the support beam 4 has a beam body 41 and a mounting flange 42, the mounting flange 42 is disposed around the beam body 41 along an edge of the beam body 41, the mounting flange 42 is fixedly connected with the mounting side member 3 and the floor pan 1 so that the support beam 4 is assembled between the corresponding mounting side member 3 and the threshold beam 2, and the support beam 4 is fixedly connected with both the mounting side member 3 and the floor pan 1, thereby satisfying the structural strength requirement of the vehicle body structure 100.

In some embodiments, the supporting beam 4 may be an integrally formed part, i.e. the supporting beam 4 is formed at one time, the beam body 41 and the mounting flange 42 are formed as one piece, for example, the supporting beam 4 is made by an integral stamping process, or alternatively, the supporting beam 4 is made by an integral casting process, so that the supporting beam 4 is an integrally formed part, the connection strength of the beam body 41 and the mounting flange 42 is ensured, the beam body 41 and the mounting flange 42 are prevented from being separated from each other, and meanwhile, the supporting beam 4 is ensured to have better structural strength,

In some embodiments, the supporting beam 4 may be a split piece, that is, the supporting beam 4 is assembled by the beam body 41 and the mounting flange 42, so that when the structure of the supporting beam 4 is complex and is difficult to be manufactured by adopting an integral molding process, the supporting beam 4 may be designed as a split piece, so that the supporting beam 4 is convenient to be manufactured, the difficult production is reduced, and the cost can be reduced. For example, when the supporting beam 4 is designed as a separate piece, after the beam body 41 and the mounting flange 42 are made separately, a welding process may be used to weld the beam body 41 and the mounting flange 42 into a single body, so as to facilitate the subsequent assembly of the supporting beam to the chassis floor 1.

In some embodiments of the present utility model, as shown in connection with fig. 2 and 5, the beam body 41 and the chassis floor 1 together define a cavity structure 40. As shown in fig. 2 and 5, the inside of the beam body 41 is formed with a groove structure, and the mounting flange 42 is disposed around the edge of the beam body 41 near the open end of the groove structure, so that when the supporting beam 4 is assembled with the chassis floor 1, the chassis floor 1 shields the open end of the groove structure, so that the beam body 41 and the chassis floor 1 together define the cavity structure 40, thereby facilitating the conduction of the acting force, avoiding the concentration of stress, and improving the structural strength of the vehicle body structure 100.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the beam body 41 is formed with a through hole structure 410, for example, the through hole structure 410 may be configured as a weeping hole, and the through hole structure 410 communicates with a groove structure of the beam body 41, thereby avoiding the risk of occurrence of liquid accumulation in the groove structure of the beam body 41, or alternatively, the through hole structure 410 may be configured as a mounting hole, the through hole structure 410 may be configured as a fixing bracket for mounting a wire harness of a vehicle, or alternatively, the through hole structure 410 may be configured as a lightening hole, so that the mass of the supporting beam 4 is reduced, thereby realizing a lightweight design of the vehicle body structure 100.

In some embodiments of the present utility model, as shown in connection with fig. 1, 3 and 5, the chassis floor 1 is formed with crush slots 5, the crush slots 5 being located between the threshold beams 2 and the corresponding support cross beams 4, the crush slots 5 being used to induce crush, through which a portion of the force can be absorbed, so that the vehicle body structure 100 has an energy absorbing function, avoiding excessive deformation of the vehicle body structure 100 after impact.

Since one end of the support cross member 4 is fixedly connected to the corresponding installation side member 3 in the width direction of the vehicle and the other end of the support cross member 4 is spaced apart from the corresponding threshold beam 2, the structural strength of the region spaced apart from the support cross member 4 and the threshold beam 2 is relatively low, and therefore, as shown in fig. 5, in the width direction of the vehicle, the region having the threshold beam 2 may be configured as the secondary buffer region H2, the region spaced apart from the support cross member 4 and the threshold beam 2 may be configured as the primary buffer region H1, the region having the support cross member 4 may be configured as the deformation resistant region H3, the structural strength of the primary buffer region H1 is Q1, the structural strength of the secondary buffer region H2 is Q2, and the structural strength of the deformation resistant region H3 is Q3, satisfying the relationship: q1 is less than Q2 and less than Q3.

As shown in fig. 5, in the process of the threshold beam 2 being impacted, since Q1 < Q2 < Q3, the impact force acts on the structure of the primary buffer zone H1, so that the primary buffer zone H1 first collapses and deforms to absorb part of the force, when the impact force fully collapses and deforms the structure of the primary buffer zone H1, the impact force acts on the structure of the secondary buffer zone H2, so that the structure of the secondary buffer zone H2 collapses and deforms, if the impact force fully collapses and deforms the structure of the secondary buffer zone H2, the impact force acts on the structure of the deformation resisting zone H3, and since the deformation resisting zone H3 has the supporting cross beam 4, the deformation resisting zone H3 has stronger structural strength, and the risk of structural deformation of the deformation resisting zone H3 is reduced.

Therefore, one end of the supporting cross beam 4 is fixedly connected with the corresponding mounting longitudinal beam 3, and the other end of the supporting cross beam 4 is spaced from the corresponding threshold beam 2, so that the vehicle body structure 100 has the function of absorbing energy in multiple stages, and the vehicle body structure 100 is prevented from being excessively deformed after being impacted by inducing the collapse deformation of the vehicle body structure 100, so that the vehicle adopting the vehicle body structure 100 provided by the embodiment of the utility model has higher safety.

In addition, in the process that the vehicle body structure 100 is subjected to impact deformation, after the structure of the primary buffer zone H1 is completely collapsed and deformed, the structure of the secondary buffer zone H2 is abutted with the structure of the deformation resisting zone H3, so that the structure of the deformation resisting zone H3 plays a supporting role on the structure of the secondary buffer zone H2 in the width direction of the vehicle, so that the structure of the secondary buffer zone H2 can be effectively collapsed and deformed, and the energy absorbing effect of the vehicle body structure 100 is ensured.

As shown in fig. 1, 3 and 5, the crumple groove 5 is located in the primary buffer zone H1, so that the crumple deformation of the primary buffer zone H1 is induced, and the energy absorption effect of the vehicle body structure 100 is ensured.

In some embodiments of the present utility model, as shown in fig. 3 to 5, the crush slots 5 are extended along the length direction of the vehicle, and since the crush slots 5 are located in the primary buffer area H1, the crush slots 5 are continuous strip-shaped slot structures along the length direction of the vehicle, so that the structure of the primary buffer area H1 can be effectively crushed and deformed, and further, the energy absorbing effect of the vehicle body structure 100 is ensured.

In some embodiments of the present utility model, as shown in fig. 4, the projection plane of the crush can 5 needs to be coincident with the projection plane of the plurality of corresponding supporting beams 4 along the width direction of the vehicle, and it may also be understood that the length of the crush can 5 needs to be ensured to pass through the plurality of corresponding supporting beams 4 along the length direction of the vehicle, so that the plurality of supporting beams 4 located between the mounting stringers 3 and the corresponding threshold beams 2 can be arranged corresponding to the corresponding crush can 5 along the width direction of the vehicle, thereby ensuring the regularity of the deformation process.

In some embodiments of the utility model, as shown in connection with fig. 3-5, the chassis floor 1 is formed with a reinforcement rib 6, which reinforcement rib 6 is located between the threshold beam 2 and the corresponding installation stringer 3, improving the structural strength of the chassis floor 1. As shown in connection with fig. 3-5, in some embodiments, the stiffener 6 is located in the deformation-resistant region H3, and improves the structural strength of the chassis floor 1 located in the deformation-resistant region H3, thereby improving the overall structural strength of the deformation-resistant region H3, and reducing the risk of excessive deformation of the vehicle body structure 100.

In some embodiments of the present utility model, as shown in connection with fig. 3 to 5, the reinforcing ribs 6 are provided to extend in the width direction of the vehicle to increase the structural strength of the chassis floor 1 in the width direction of the vehicle, thereby increasing the overall structural strength of the deformation resistant region H3 and reducing the risk of excessive deformation of the vehicle body structure 100.

In some embodiments, as shown in connection with fig. 1 and 4, the chassis floor 1 may include a first plate 11 and two second plates 12, the first plate 11 is connected between the two second plates 12 in the width direction of the vehicle, and the second plates 12 are also fixedly connected with the corresponding threshold beams 2, so as to achieve the effect that the chassis floor 1 is connected between the two threshold beams 2, and the installation stringers 3 and the support cross members 4 are both assembled to the second plates 12.
