The torsion box is usually arranged in the vehicle, the relative fixation between the front longitudinal beam and the threshold beam is realized through the torsion box, and meanwhile, the torsion box can also play a role in force transmission, so that when the vehicle is impacted, impact force can be dispersed to different positions of the vehicle body, and the impact resistance of the vehicle is improved.

However, the existing torsion box is generally of an integral structure, and can only meet the requirement of mounting a front longitudinal beam or a threshold beam of a specific size, so that the mounting applicability is poor. And after the front longitudinal beam and the torsion box are installed, the front longitudinal beam and the torsion box are easy to loose relatively under the action of external force, so that potential safety hazards are easy to appear, and long-term use of the vehicle is not facilitated.

In order to solve the above-described problems, the embodiment of the present application provides a torsion box and a vehicle capable of improving the mounting reliability between the torsion box and a front side member.

Referring to fig. 1 to 6, the torsion box provided in the embodiment of the present application includes a first member 10 and a second member 20, the first member 10 includes a rocker mounting portion 11 and a front side member mounting portion 12 that are disposed side by side in a first direction X, the rocker mounting portion 11 is used to connect a rocker 40 of a vehicle, the front side member mounting portion 12 is used to connect a front side member 50 of the vehicle, and the front side member 50 extends in the first direction X. The second member 20 is provided on one side of the front side member mounting portion 12 in the second direction Y, and encloses with the front side member mounting portion 12 a first mounting cavity A1 extending in the first direction X, which intersects the second direction Y.

The first member 10 includes at least two parts, a rocker mounting portion 11 and a front side member mounting portion 12, and the rocker mounting portion 11 is used to make a connection with the rocker 40, including but not limited to a bolt connection, an FDS connection, and the like. The front side member attachment portion 12 is used to make a connection with the front side member 50, including, but not limited to, a bolt connection, an FDS connection, and the like. Illustratively, a plurality of mounting holes are provided in the front side member mounting portion 12, and the front side member 50 is fixed to the front side member mounting portion 12 by bolting.

Since the extending directions of both the rocker 40 and the front side member 50 are the first direction X, and both are located at both ends of the torsion box in the first direction X, respectively. Therefore, the rocker mounting portion 11 and the front side member mounting portion 12 for connecting the rocker 40 and the front side member 50 in correspondence with each other are provided side by side in the first direction X, and may be integrally formed or separately formed, and fixed by bolts, welding, or the like, which is not limited to this embodiment.

The second member 20 is a separate structure from the first member 10, and the second member 20 is connected to the first member 10 and located on one side of the front side member attaching portion 12 in the second direction Y. Illustratively, the first direction X is disposed perpendicular to the second direction Y. The connection manner between the first member 10 and the second member 20 is not limited in this embodiment, as long as it is satisfied that the first member 10 and the second member 20 can be kept relatively fixed, and the first member 10 is illustratively bolted to the second member 20.

The second member 20 can form a first mounting cavity A1 extending in the first direction X in cooperation with the front side member mounting portion 12, the first mounting cavity A1 being for accommodating at least part of the structure of the front side member 50. In other words, the front side member 50 is inserted in the first mounting cavity A1. The existence of the first installation cavity A1 can play a limiting role on the position of the front longitudinal beam 50, so that stability between the front longitudinal beam 50 and the torsion box is improved, and the risk of loosening and separating the front longitudinal beam 50 and the torsion box due to external impact and other factors is reduced.

The size and shape of the first installation cavity A1 are determined by the front side member installation portion 12 and the second member 20, and the second member 20 is adjusted to change the size and shape of the first installation cavity A1, so that the installation of the front side member 50 with different sizes can be adapted, and the universality is high.

In summary, the torsion box in the embodiment of the present application includes at least two parts, namely, the first member 10 and the second member 20, and the first member 10 enables a fixed connection between the rocker 40 and the front side member 50. The first component 10 and the second component 20 can be connected and enclose to form a first installation cavity A1, so as to limit the position of the front longitudinal beam 50, reduce the probability of the front longitudinal beam 50 being separated from the torsion box due to external impact and other factors, and improve the structural stability between the torsion box and the front longitudinal beam 50.

In some embodiments, as shown in fig. 1 and 6, the front side rail mounting portion 12 includes a first riser 121 and a first bulkhead 122 extending from the first riser 121 toward the second member 20, and the second member 20 includes a second riser 21 and a second bulkhead 22 extending from the second riser 21 toward the front side rail mounting portion 12. The first and second standing

plates

121 and 21 are disposed at intervals in the second direction Y by the first and

second partition plates

122 and 22 to form a first installation cavity A1.

The front side member mounting portion 12 includes a first riser 121 and a first bulkhead 122, the first riser 121 and the first bulkhead 122 being connected to each other and disposed so as to intersect each other, the first riser 121 being, illustratively, perpendicular to the second direction Y, and the first bulkhead 122 being at least partially disposed perpendicular to the first riser 121. As for the connection relationship between the first partition 122 and the first riser 121, the embodiment of the present application is not limited, and the first partition 122 and the first riser 121 are exemplarily configured as a single body.

The front side member 50 may be fixedly connected to the first riser 121, the first bulkhead 122, or both the first riser 121 and the first bulkhead 122. Illustratively, the first riser 121 is provided with a mounting hole penetrating in the second direction Y, and the front side member 50 is fixedly connected to the first riser 121.

The second member 20 includes a second riser 21 and a second partition 22, the second riser 21 and the first partition 122 being connected to each other and disposed so as to intersect each other, the second riser 21 being, illustratively, perpendicular to the second direction Y, and the second partition 22 being at least partially disposed perpendicular to the second riser 21. As for the connection relationship between the second partition 22 and the second riser 21, the present application is not limited in implementation, and the second partition 22 and the second riser 21 are illustratively in a unitary structure.

Since the first bulkhead 122 and the second bulkhead 22 each have a certain size in the second direction Y, after the front side member mounting portion 12 is connected to the second member 20, the first riser 121 and the second riser 21 are disposed at intervals in the second direction Y, thereby forming a first mounting cavity A1 for accommodating at least part of the front side member 50. Wherein the dimensions of the first mounting cavity A1 in the second direction Y depend on the dimensions of the first partition 122 and the second partition 22 in the second direction Y. Illustratively, the first separator 122 is the same size as the second separator 22 in the second direction Y.

In the embodiment of the present application, the first bulkhead 122 is provided in the front side member mounting portion 12, and the second bulkhead 22 is provided in the second member 20, so that the first and second standing

plates

121 and 21 are arranged at intervals in the second direction Y, and thus the first mounting chamber A1 for accommodating at least part of the structure of the front side member 50 can be formed. On the basis, the first installation cavities A1 with different sizes can be formed by adjusting the sizes of the first partition plate 122 and the second partition plate 22 in the second direction Y, so that the installation requirements of the front longitudinal beams 50 with different sizes are met, and the flexibility and the universality are high.

In some embodiments, the first partition 122 is detachably connected to the second riser 21; and/or the second partition 22 is detachably connected with the first riser 121.

During use of the torque box, the second member 20 needs to remain relatively fixed to the front side rail mounting portion 12 and therefore needs to be fixedly attached thereto. At this time, the fixation between the second member 20 and the front side member mounting portion 12 may be achieved by connecting the first bulkhead 122 and the second riser 21; alternatively, the second member 20 may be fixed to the front side member mounting portion 12 by connecting the second bulkhead 22 to the first riser 121.

On this basis, in order to facilitate the subsequent maintenance and replacement of the torsion box and the front side member 50, the embodiment of the present application further provides the first bulkhead 122 and the second riser 21 to be detachably connected, or provides the second bulkhead 22 and the first riser 121 to be detachably connected. Taking the detachable connection of the first partition 122 and the second riser 21 as an example, in this embodiment, the first partition 122 and the first riser 121 may be detached, so as to separate the first component 10 from the second component 20, and further, the front longitudinal beam 50 and the torsion box may be detached by separating the front longitudinal beam 50 from the first component 10.

Compared with the scheme that the front longitudinal beam 50 and the torsion box are integrally connected, the front longitudinal beam 50 or the torsion box can be replaced and maintained respectively, so that maintenance cost of vehicle parts is reduced, and the torsion box is suitable for long-term use of a vehicle.

In some embodiments, as shown in fig. 3 and 4, the rocker mounting portion 11 includes a baffle 111 and a mounting member 112 located on one side of the baffle 111 in the second direction Y.

The baffle 111 is a plate-shaped structure, the threshold beam 40 is located at one side of the baffle 111 in the second direction Y, the baffle 111 can play a certain limiting role on the threshold beam 40, and the probability of relative movement of the threshold beam 40 in the second direction Y under the influence of external force and other factors is reduced. Illustratively, the baffle 111 is disposed perpendicular to the second direction Y.

The mounting member 112 is used to achieve the relative fixation between the threshold beam 40 and the torsion box, and the form of the mounting member 112 is various, and illustratively, the mounting member 112 includes a protrusion structure, a recess or a through hole structure corresponding to the protrusion structure is provided on the threshold beam 40, and the mounting member 112 is inserted into the threshold beam 40, thereby achieving the relative fixation between the threshold beam 40 and the torsion box.

The mounting member 112 is located on one side of the apron 111 in the second direction Y, and the position of the mounting member 112 determines the position of the sill beam 40 relative to the torsion box, so that by adjusting the specific position of the mounting member 112 relative to the apron 111, a change in the relative position of the sill beam 40 can be achieved, whereby the structural layout between the torsion box and the sill beam 40 can be optimized.

It should be noted that the mounting member 112 may be directly connected to the baffle 111, or alternatively, the mounting member 112 may not be connected to the baffle 111 in contact, but may be located on one side of the baffle 111 in the second direction Y, which is not limited in the embodiment of the present application.

In some embodiments, as shown in fig. 4, the height of the mounting member 112 is lower than the height of the front rail mounting portion 12.

As can be seen from the foregoing, the position of the mounting member 112 determines the position of the threshold beam 40, and in order to meet the requirement of a person entering the vehicle, the position of the threshold beam 40 is usually set low, so as to reduce the risk of collision between the person and the threshold beam 40.

On this basis, the present embodiment sets the height of the mount 112 to be lower than the height of the front side member mounting portion 12 so that the relative position of the rocker 40 on the torsion box is lower than the relative position of the front side member 50 on the torsion box, thereby satisfying the mounting requirements of the rocker 40 and the front side member 50 as much as possible.

In some embodiments, as shown in fig. 3, the torque box further includes a stiffener structure 30, the stiffener structure 30 being disposed on at least one of the first and

second components

10, 20.

The reinforcing bead structure 30 in the embodiment of the present application refers to a bead structure capable of improving structural strength. The reinforcing rib structure 30 may be formed on the torsion box by welding or may be integrally formed with the first member 10 or the second member 20. Illustratively, the stiffener structure 30 may be formed by stamping the first component 10 or the second component 20.

In the embodiment of the application, by providing the reinforcing rib structure 30 on at least one of the first component 10 and the second component 20, the structural strength of the first component 10 or the second component 20 is improved, the risk that the first component 10 and the second component 20 deform due to external force factors is reduced, and the impact resistance and safety of the vehicle are improved.

In some embodiments, as shown in FIG. 3, at least a portion of the stiffener structure 30 is disposed on the baffle 111 and the mounting member 112 is coupled to the stiffener structure 30.

The reinforcing rib structure 30 is arranged on the baffle 111, and the structural strength of the baffle 111 can be improved due to the existence of the reinforcing rib structure 30, so that the risk of deformation of the baffle 111 is reduced. Meanwhile, the reinforcing rib structure 30 can space the threshold beam 40 from the baffle 111, so that when the threshold beam 40 relatively shakes due to external force, the threshold beam 40 is not in direct contact with the baffle 111, but the external force is transmitted to the baffle 111 through the reinforcing rib structure 30, thereby reducing the risk of deformation of the baffle 111 and prolonging the service life of the baffle 111.

Further, due to the presence of the stiffener structure 30, the mounting member 112 may be provided on the stiffener structure 30 instead of being mounted on the baffle 111. This design can simultaneously improve the structural strength of the mounting member 112, ensuring the connection reliability between the torsion box and the threshold beam 40.

In some embodiments, referring to fig. 3 and 7, at least a portion of the stiffener structure 30 is located on both sides of the baffle 111 in the second direction Y.

The shutter 111 has two opposite surfaces in the second direction Y, and the mount 112 is located at one side of the shutter 111 in the second direction Y. On this basis, this application embodiment divides the strengthening rib structure 30 to establish in the both sides of baffle 111, can further improve the structural strength of baffle 111 to further reduce the risk that baffle 111 takes place to warp because of external force impact, improve the bulk strength of torsion box.

The embodiments of the present application are not limited with respect to the specific dimensional configuration of the stiffener structure 30. The reinforcing rib structure 30 may be a rib structure extending in a single direction or may be a rib structure extending in a plurality of directions.

In some embodiments, as shown in fig. 3, the stiffener structure 30 includes a first stiffener 31 extending in a first direction X, and a second stiffener 32 extending in a third direction Z, where the first direction X, the second direction Y, and the third direction Z intersect one another. Illustratively, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

The first reinforcing ribs 31 extend along the first direction X, so that the structural strength of the torsion box in the first direction X can be improved, and the risk of deformation of the torsion box in the first direction X can be reduced. The second reinforcing ribs 32 extend along the third direction Z, so that the structural strength of the torsion box in the third direction Z can be improved, and the risk of deformation of the torsion box in the third direction Z can be reduced.

According to the embodiment of the application, the first reinforcing rib 31 extending along the first direction X and the second reinforcing rib 32 extending along the third direction Z are arranged on the reinforcing rib structure 30, so that the deformation resistance of the torsion box in the first direction X and the third direction Z is improved, the structural strength of the torsion box is further improved, and the safety of a vehicle is improved.

In some embodiments, as shown in fig. 1 and 2, the first component 10 further includes a beam mount 13 disposed on a side of the baffle 111 facing away from the mount 112.

The beam mounting portion 13 is used for realizing the installation between the torsion box and the beam 60, the beam 60 extends along the second direction Y, the beam 60 and the threshold beam 40 are respectively located at two sides of the baffle 111 in the second direction Y, and the risk of contact interference between the threshold beam 40 and the beam 60 can be reduced due to the existence of the baffle 111, so that the reliability of the relative position between the two is improved.
