[0046] When the battery pack of a vehicle is extruded by an external force from the side, there is a risk of spontaneous combustion, fire, and explosion. The body sill structure of the vehicle plays a protective role in the side of the battery pack.

[0047] In the prior art, usually, the thickness and size of the body sill structure are increased to improve the compressive capacity of the body sill structure.

[0048] However, by increasing the thickness and size of the body sill structure, the existing body sill structure is heavy in weight and low in the ability to absorb the side extrusion force, resulting in a relatively low protective effect on the battery pack and making it easy for the battery pack to be extruded.

[0049] In order to solve the technical problems of the heavy weight of the existing body sill structure and the low ability to absorb side extrusion force, the present application proposes a body sill structure, including an inner floor sill assembly, an outer side panel, and an energy absorption member; the inner floor sill assembly is used to be arranged on the vehicle body, the inner floor sill assembly is connected to the outer side panel to form an energy absorption cavity, the energy absorption member is arranged in the energy absorption cavity, and a chamber is arranged in the energy absorption member. The energy absorption member is configured to deform when being extruded, so that the chamber deforms to absorb the extrusion force.

[0050] Since the inner floor sill assembly of the body sill structure of the present application is connected to the outer side panel to form an energy absorption cavity, an energy absorption member is arranged in the energy absorption cavity, and a chamber is arranged in the energy absorption member. When the vehicle body side is subjected to an extrusion force, the extrusion force is sequentially transmitted to the outer side panel, the energy absorption member, and the inner floor sill assembly. When the extrusion force is transmitted to the energy absorption member, due to the chamber arranged in the energy absorption member, when the energy absorption member is extruded, the energy absorption member deforms and causes the chamber to deform, so that the energy absorption member absorbs the extrusion force, and further reduces the extrusion force transmitted to the inner floor sill assembly. Thus, the extrusion force transmitted to the battery pack is absorbed and reduced, playing a protective role for the battery pack. And because there is a chamber arranged in the energy absorption member, that is, the energy absorption member is a hollow structure, the weight of the energy absorption member is reduced. Compared with the existing thickened and enlarged body sill structure, the body sill structure of the present application is light in weight and strong in the ability to absorb the extrusion force, improving the protective effect on the battery pack.

[0051] The following will specifically describe the technical solutions of the application in detail with reference to the accompanying drawings. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0052] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 as shown, Figure 1 which is a schematic structural diagram of the vehicle body in the vehicle provided by the embodiment of the present application; Figure 2 is Figure 1 the cross-sectional structural diagram in the A-A direction in Figure 3 which is a schematic structural diagram of the energy absorption member in the body sill structure provided by the embodiment of the present application; Figure 4 is Figure 3 the cross-sectional structural diagram in the B-B direction in Figure 5 is Figure 3 the cross-sectional structural diagram in the C-C direction in

[0053] In the embodiment of the present application, referring to Figure 1 and Figure 2 as shown, the embodiment of the present application provides a body sill structure, including an inner floor sill assembly 100, an outer side panel 200, and an energy absorption member 300.

[0054] The floor inner sill assembly 100 is used to be arranged on the vehicle body 10. The floor inner sill assembly 100 is connected to the outer panel of the side wall 200 to form an energy absorption cavity 900. An energy absorption member 300 is arranged in the energy absorption cavity 900. A chamber 400 is arranged in the energy absorption member 300. The energy absorption member 300 is configured to be deformed when being extruded, so that the chamber 400 is deformed to absorb the extrusion force.

[0055] Refer to Figure 2 As shown, the vehicle body 10 includes a seat crossbeam assembly 11, a short seat lower crossbeam assembly 12, a floor panel 13, a seat mounting bracket 14, a front floor longitudinal beam assembly 15, a battery pack 16, etc. The floor inner sill assembly 100 of the present application is respectively lapped on the seat crossbeam assembly 11 of the vehicle body 10 and the short seat lower crossbeam assembly 12 of the vehicle body 10.

[0056] The floor inner sill assembly 100 is connected to the outer panel of the side wall 200 to form an energy absorption cavity 900. When the side of the vehicle body 10 is subjected to an extrusion force, the energy absorption cavity 900 can be deformed and can also absorb part of the extrusion force.

[0057] The energy absorption member 300 is arranged in the energy absorption cavity 900. A chamber 400 is arranged in the energy absorption member 300. When the energy absorption member 300 is extruded, the chamber 400 is deformed, so that the energy absorption member 300 can absorb the extrusion force, thereby reducing the extrusion force transmitted to the floor inner sill assembly 100, and further reducing the extrusion on the battery pack 16, playing a role in protecting the battery pack 16.

[0058] By arranging the vehicle body sill structure of the present application on the vehicle body 10, refer to Figure 2 As shown, D1, D2, D3 and D4 are lower regions, D5 is an upper region, the region between D1 and D2 is an energy absorption deformation region, the region between D3 is a micro-deformation region, the region between D4 is a rigid region, and the region between D5 is a rigid region, thereby increasing the protection ability for the battery pack 16.

[0059] Since the inner floor sill assembly 100 of the vehicle body sill structure of the present application is connected to the outer side panel 200 to form an energy absorption cavity 900, an energy absorption member 300 is disposed in the energy absorption cavity 900, and a cavity 400 is disposed in the energy absorption member 300. When the side of the vehicle body 10 is subjected to a squeezing force, the squeezing force is sequentially transmitted to the outer side panel 200, the energy absorption member 300, and the inner floor sill assembly 100. When the squeezing force is transmitted to the energy absorption member 300, since the cavity 400 is disposed in the energy absorption member 300, when the energy absorption member 300 is squeezed, the energy absorption member 300 is deformed, and the cavity 400 is deformed, so that the energy absorption member 300 absorbs the squeezing force, thereby reducing the squeezing force transmitted to the inner floor sill assembly 100, and thus the squeezing force transmitted to the battery pack 16 is absorbed and reduced, which plays a protective role for the battery pack 16. And because the cavity 400 is disposed in the energy absorption member 300, that is, the energy absorption member 300 is a hollow structure, the weight of the energy absorption member 300 is reduced. Compared with the existing thickened and enlarged vehicle body sill structure, the vehicle body sill structure of the present application is light in weight and strong in the ability to absorb the squeezing force, improving the protection effect on the battery pack 16.

[0060] In another embodiment, the energy absorption member 300 includes a first housing 310 and a second housing 320. The first housing 310 and the second housing 320 are arranged in sequence from the inner floor sill assembly 100 to the outer side panel 200. The cavity 400 includes a first deformation cavity 410 and a second deformation cavity 420. The first deformation cavity 410 is disposed in the first housing 310, and the second deformation cavity 420 is disposed in the second housing 320.

[0061] In this embodiment, since the energy absorption member 300 includes the first housing 310 and the second housing 320, and the cavity 400 includes the first deformation cavity 410 and the second deformation cavity 420, that is, the energy absorption member 300 has two deformation cavities, and both deformation cavities can absorb energy and deform. Since the first housing 310 and the second housing 320 are arranged in sequence from the inner floor sill assembly 100 to the outer side panel 200, that is, when the side of the vehicle body 10 is subjected to a squeezing force, the squeezing force is sequentially transmitted to the outer side panel 200, the second housing 320, the first housing 310, and the inner floor sill assembly 100, and the squeezing force is sequentially absorbed by the second deformation cavity 420 and the first deformation cavity 410, further reducing the squeezing force transmitted to the inner floor sill assembly 100 and further protecting the battery pack 16.

[0062] It should be noted that the first housing 310 and the second housing 320 can be connected by laser welding, and of course, they can also be connected by other means, such as snap connection, adhesive bonding, screw connection, etc. The first housing 310 and the second housing 320 can be processed by a rolling process, reducing the cost compared with the existing extruded aluminum parts.

[0063] In other embodiments, the cross-section of the first deformation cavity 410 is trapezoidal, the cross-section of the second deformation cavity 420 is rectangular, and the volume of the first deformation cavity 410 is greater than the volume of the second deformation cavity 420.

[0064] In this embodiment, when the side of the vehicle body 10 is subjected to a squeezing force, since the squeezing force first passes through the second deformation cavity 420 and then through the first deformation cavity 410, because the cross-section of the second deformation cavity 420 is rectangular and the cross-section of the first deformation cavity 410 is trapezoidal, that is, the first housing 310 is more easily deformed than the second housing 320. That is to say, the squeezing force first passes through the second housing 320 with stronger rigidity, so that a large amount of the squeezing force is absorbed, and then passes through the first housing 310, so that the squeezing force applied to the first housing 310 is reduced.

[0065] And because the volume of the first deformation cavity 410 is greater than the volume of the second deformation cavity 420, at this time, the projection of the second housing 320 towards the first housing 310 is located within the first housing 310, so as to ensure that after the second housing 320 is subjected to a squeezing force, the deformed second housing 320 can be pushed towards the first housing 310 by the squeezing force, thereby further absorbing the squeezing force.

[0066] In some embodiments, at least one first connecting member 500 is further included. At least one first connecting hole 311 and at least one first mounting through hole 312 are provided on the first housing 310. Each first connecting hole 311 communicates with each first mounting through hole 312 in a one-to-one correspondence. The first connecting member 500 is configured to pass through the first mounting through hole 312 and be disposed on the first connecting hole 311 to connect the first housing 310 with the floor inner sill assembly 100.

[0067] In this embodiment, referring to Figure 3 and Figure 5 As shown, the first mounting through hole 312 is used for the first connecting member 500 to pass through to the first connecting hole 311, facilitating the installation of the first connecting member 500 on the first mounting through hole 312, thereby connecting the first housing 310 with the floor inner sill assembly 100. For example, the first connecting member 500 is a welding part. By inserting a welding tool into the first mounting through hole 312 and then welding the solder at the first connecting hole 311, the first housing 310 is connected to the floor inner sill assembly 100 to fix the first housing 310.

[0068] Furthermore, the cross-section of the first housing 310 is trapezoidal, and the cross-section of the second housing 320 is rectangular.

[0069] In this embodiment, since the cross-section of the first housing 310 is trapezoidal, the first mounting through hole 312 can be provided on the waist side of the first housing 310, which facilitates the installation of the first connecting member 500 on the first mounting through hole 312.

[0070] In another embodiment, a second connecting member 600 is further included. At least one second connecting hole 313 and at least one second mounting through-hole 314 are provided on the first housing 310. At least one mounting channel 321 is provided on the second housing 320. Each second connecting hole 313 communicates with each second mounting through-hole 314 in one-to-one correspondence, and each mounting channel 321 communicates with each second mounting through-hole 314 in one-to-one correspondence. The second connecting member 600 is configured to sequentially pass through the mounting channel 321 and the second mounting through-hole 314 and be disposed on the second connecting hole 313 to connect the first housing 310 to the floor inner sill assembly 100.

[0071] In this embodiment, with reference to Figure 3 and Figure 4 as shown, by adding the second connecting member 600, the connection between the first housing 310 and the floor inner sill assembly 100 becomes more stable, ensuring the connection strength between the first housing 310 and the floor inner sill assembly 100.

[0072] It should be noted that the settings of the first connecting hole 311, the first mounting through-hole 312, the second connecting hole 313, the second mounting through-hole 314, and the mounting channel 321 all reduce the weight of the energy-absorbing member 300, thereby reducing the weight of the entire body sill structure.

[0073] In some embodiments, both the first connecting member 500 and the second connecting member 600 include welding parts.

[0074] In this embodiment, the first housing 310 is connected to the floor inner sill assembly 100 by welding, and the welding parts can be welded by a laser welding process. Of course, the first connecting member 500 and the second connecting member 600 may also include bolts, snap connectors, etc.

[0075] It should be noted that a plurality of first connecting holes 311 and a plurality of second connecting holes 313 may be provided on the first housing 310, so as to form two rows of welding points on the first housing 310, improving the fixing strength of the first housing 310, ensuring that the first housing 310 can be stably fixed on the floor inner sill assembly 100, and further improving the collision performance and the torsional stiffness of the vehicle body 10.

[0076] Both the first connecting member 500 and the second connecting member 600 further include bonding parts. Through the double fixation of the welding parts and the bonding parts, the first housing 310 is fixed more stably.

[0077] In other embodiments, a mounting bracket 700 is further included, and the second housing 320 is connected to the floor inner sill assembly 100 through the mounting bracket 700.

[0078] In this embodiment, to prevent the second housing 320 from shaking, the second housing 320 is connected to the floor inner sill assembly 100 through the mounting bracket 700, ensuring the stability of the fixation of the second housing 320.

[0079] Furthermore, the mounting bracket 700 includes a first frame body 710, a second frame body 720, and a third frame body 730, and the first frame body 710, the second frame body 720, and the third frame body 730 are arranged at intervals along the length direction of the floor inner sill assembly 100.

[0080] In this embodiment, the length direction of the floor inner sill assembly 100 is the length direction of the vehicle body 10. By fixing the second housing 320 simultaneously with the first frame body 710, the second frame body 720, and the third frame body 730, the up-and-down shaking of the second housing 320 can be prevented, ensuring that the second housing 320 is fixed more stably.

[0081] Furthermore, the length of the energy absorption member 300 is greater than or equal to the length of the battery pack 16 in the vehicle body 10. The length direction of the battery pack 16 is the length direction of the vehicle body 10.

[0082] In this embodiment, when the side of the vehicle body 10 is subjected to a squeezing force, since the length of the energy absorption member 300 is greater than or equal to the length of the battery pack 16 in the vehicle body 10, the energy absorption member 300 plays a protective role for the entire length side of the battery pack 16.

[0083] In a possible embodiment, it further includes a sidewall door ring reinforcement plate 800. The sidewall door ring reinforcement plate 800 is arranged between the energy absorption member 300 and the outer sidewall panel 200, and there is a gap between the sidewall door ring reinforcement plate 800 and the energy absorption member 300.

[0084] In this embodiment, the sidewall door ring reinforcement plate 800 plays a role in strengthening the protection of the energy absorption member 300. And since there is a gap between the sidewall door ring reinforcement plate 800 and the energy absorption member 300, when the side of the vehicle body 10 is subjected to a squeezing force, the squeezing force will not be immediately transmitted to the energy absorption member 300. The gap between the sidewall door ring reinforcement plate 800 and the energy absorption member 300 plays a role in buffering and energy absorption, reducing the force on the energy absorption member 300.

[0085] Furthermore, a buffer sponge is arranged in the gap between the sidewall door ring reinforcement plate 800 and the energy absorption member 300. The buffer sponge plays a role in buffering and energy absorption for the squeezing force, further reducing the force on the energy absorption member 300.

[0086] The second aspect of the embodiments of the present application provides a vehicle, including a vehicle body 10, and further including the body sill structure of any of the above embodiments, and the body sill structure is arranged on the vehicle body 10.

[0087] Since the vehicle body 10 of the present application is provided with the body sill structure of the present application, the body sill structure includes an inner floor sill assembly 100, an outer side panel 200, and an energy-absorbing member 300; the inner floor sill assembly 100 is configured to be disposed on the vehicle body 10, the inner floor sill assembly 100 is connected to the outer side panel 200 to form an energy-absorbing cavity 900, the energy-absorbing member 300 is disposed in the energy-absorbing cavity 900, and a chamber 400 is disposed in the energy-absorbing member 300. The energy-absorbing member 300 is configured to deform when being squeezed, so that the chamber 400 deforms to absorb the squeezing force.

[0088] Because the inner floor sill assembly 100 is connected to the outer side panel 200 to form an energy-absorbing cavity 900, the energy-absorbing member 300 is disposed in the energy-absorbing cavity 900, and the chamber 400 is disposed in the energy-absorbing member 300. When the side of the vehicle body 10 is subjected to a squeezing force, the squeezing force is sequentially transmitted to the outer side panel 200, the energy-absorbing member 300, and the inner floor sill assembly 100. When the squeezing force is transmitted to the energy-absorbing member 300, since the chamber 400 is disposed in the energy-absorbing member 300, when the energy-absorbing member 300 is squeezed, the energy-absorbing member 300 deforms and causes the chamber 400 to deform. Thus, the energy-absorbing member 300 absorbs the squeezing force, and further reduces the squeezing force transmitted to the inner floor sill assembly 100. As a result, the squeezing force transmitted to the battery pack 16 is absorbed and reduced, which plays a protective role for the battery pack 16. And because the chamber 400 is disposed in the energy-absorbing member 300, that is, the energy-absorbing member 300 is a hollow structure, the weight of the energy-absorbing member 300 is reduced. Compared with the body sill structure of the existing vehicle, the body sill structure of the vehicle of the present application is lightweight and has a strong ability to absorb the squeezing force, which improves the protective effect on the battery pack 16.

[0089] After considering the specification and the practice disclosed herein, those skilled in the art will readily conceive of other embodiments of the present application.
