The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0033] Reference below Figure 1-Figure 5 A floor assembly 10 for a vehicle according to an embodiment of the present application is described, wherein the floor assembly 10 includes a first sill beam 11, a second sill beam 12, a first connecting member 14, a second connecting member 15 and a seat cross beam 16, wherein the first sill beam 11 and the second sill beam 12 are respectively arranged on both sides of a battery pack housing 13 in a width direction of the vehicle and are connected to a body of the vehicle, the first connecting member 14 is arranged on the first sill beam 11, the second connecting member 15 is arranged on the second sill beam 12, and the first connecting member 14 and the second connecting member 15 extend toward each other and are both formed with a mounting portion 1431, and energy absorbing cavities 145 are formed inside the first connecting member 14 and the second connecting member 15, and the seat cross beam 16 is arranged on the mounting portion 1431 and extends in the width direction, and the seat cross beam 16 is located between the mounting portion 1431 and the battery pack housing 13.

[0034] At present, the rear cross beam of the vehicle's seat is limited by the Z-direction space between the front seats and the battery pack during installation, resulting in a smaller Z-direction cross section and lower rigidity. When the vehicle collides, the connection between the rear cross beam and the vehicle body is easily bent and deformed, squeezing the battery pack, causing damage to the battery pack and posing a safety hazard.

[0035] like Figure 1 As shown, specifically, the floor assembly 10 may include a threshold beam and a seat cross beam 16, and the threshold beam and the seat cross beam 16 may be connected by a connecting piece, wherein the threshold beam may include a first threshold beam 11 and a second threshold beam 12, and the first threshold beam 11 and the second threshold beam 12 may be respectively arranged on both sides of the battery pack housing 13 in the width direction, and the first threshold beam 11 and the second threshold beam 12 may extend in the length direction, and the first threshold beam 11 and the second threshold beam 12 may be connected to the vehicle body. It should be noted that the width direction referred to in the present application may be the width direction of the vehicle, that is, the Y direction of the vehicle, the length direction referred to in the present application may be the length direction of the vehicle, that is, the X direction of the vehicle, and the height direction referred to in the present application may be the height direction of the vehicle, that is, the Z direction of the vehicle.

[0036] like Figure 2 As shown, the connecting member may include a first connecting member 14 and a second connecting member 15. The first connecting member 14 may be disposed on the first sill beam 11. Optionally, the first connecting member 14 and the first sill beam 11 may be directly welded and fixed via a contact surface. The first connecting member 14 may be located on a side of the first sill beam 11 facing the second sill beam 12. The second connecting member 15 may be disposed on the second sill beam 12. Optionally, the second connecting member 15 and the second sill beam 12 may be directly welded and fixed via a contact surface. The second connecting member 15 may be located on a side of the second sill beam 12 facing the first sill beam 11. It can be understood that the first connecting member 14 and the second connecting member 15 may be located in the space between the first sill beam 11 and the second sill beam 12.

[0037] Furthermore, the first connecting member 14 and the second connecting member 15 can extend toward each other, and a mounting portion 1431 is formed on the first connecting member 14 and the second connecting member 15, and the seat cross beam 16 can be arranged on the mounting portion 1431. Optionally, the seat cross beam 16 and the mounting portion 1431 can be detachably connected by screws or bolts, or the seat cross beam 16 and the mounting portion 1431 can be directly welded and fixed via contact surfaces, wherein an energy absorption cavity 145 is formed inside the first connecting member 14 and the second connecting member 15. Therefore, when the vehicle is hit sideways, the energy generated by the collision is transmitted to the energy absorption cavity 145 through the first sill beam 11 or the second sill beam 12. The energy absorption cavity 145 absorbs the energy generated by the collision by collapsing and deforming, thereby reducing the deformation of the connection between the seat cross beam 16 and the connecting member, preventing the seat cross beam 16 from damaging the battery pack due to deformation due to force, and ensuring the safety of the driver and passengers.

[0038] The seat cross beam 16 can be located between the mounting portion 1431 and the battery pack housing 13. It can be understood that the seat cross beam 16 can be connected to the side of the mounting portion 1431 facing the battery pack housing 13. In a specific embodiment, the seat cross beam 16 and the mounting portion 1431 can be connected by bolts, and the mounting portion 1431 can be constructed as a bolt hole. By locating the seat cross beam 16 between the mounting portion 1431 and the battery pack housing 13, the space occupied by the seat cross beam 16 can be reduced and the space in the cockpit can be increased. Since there is still a certain distance between the seat cross beam 16 and the battery pack housing 13, the thickness of the seat cross beam 16 (that is, the dimension of the seat cross beam 16 in the height direction) can be appropriately increased to improve the structural strength of the seat cross beam 16, so that the seat cross beam 16 has higher rigidity and is not easy to bend, and the seat cross beam 16 can provide more bearing capacity, thereby improving the overall structural strength of the floor assembly 10.

[0039] In short, the floor assembly 10 of the embodiment of the present application is provided with a first connecting member 14 and a second connecting member 15, and the first connecting member 14 and the second connecting member 15 can be respectively arranged on the first sill beam 11 and the second sill beam 12, and the first connecting member 14 and the second connecting member 15 can also be used to install the seat cross beam 16, wherein the first connecting member 14 and the second connecting member 15 are both formed with an energy absorption cavity 145, so when the vehicle has a side collision, the first connecting member 14 and the second connecting member 15 can absorb the energy generated by the collision by collapsing, thereby avoiding deformation of the connection between the seat cross beam 16 and the first connecting member 14 and the second connecting member 15, resulting in squeezing of the battery pack, thereby ensuring the safety of the driver and passengers and improving the safety performance of the vehicle.

[0040] like Figure 3 As shown, in some embodiments of the present application, the first sill beam 11 and the second sill beam 12 may include a first beam 111, a second beam 112 and a third beam 113. The first beam 111 can be connected to the battery pack housing 13, and the first beam 111 can extend in the width direction. Optionally, the first beam 111 and the battery pack housing 13 can be detachably connected by screws or bolts, or the first beam 111 and the battery pack housing 13 can be directly welded and fixed by contact surfaces. One end of the second beam 112 can be connected to the first beam 111, and the second beam 112 can extend in the height direction. The third beam 113 can be arranged at the other end of the second beam 112, and the third beam 113 can extend in the width direction. It should be noted that the first sill beam 11 and the second sill beam 12 are the sill beams facing the battery pack side in the complete sill beams of the vehicle. The first beam 111 can be connected to the battery pack housing 13, and the second beam 112 and the third beam 113 can be connected to the first connecting member 14 and the second connecting member 15, so that the first sill beam 11 and the second sill beam 12 are respectively connected to the corresponding first connecting member 14 and the second connecting member 15 and the battery.

[0041] like Figure 3-Figure 5As shown, in some embodiments of the present application, the first connecting member 14 and the second connecting member 15 may include a first plate 141, a second plate 142 and an extension plate 143. The first plate 141 may be arranged on the second beam 112, and the first plate 141 may extend toward the seat cross beam 16. In a specific embodiment, the first plate 141 and the second beam 112 may be fixed by direct welding of the contact surfaces. Fixing by welding may improve the connection strength between the first plate 141 and the second beam 112. Similarly, the second plate 142 can be arranged on the third beam 113, and the second plate 142 can extend toward the seat cross beam 16. The second plate 142 and the third beam 113 can be directly welded and fixed through the contact surface. There is a certain angle between the extension directions of the first plate 141 and the second plate 142. The extension plate 143 can be arranged at the connection between the free end of the first plate 141 and the free end of the second plate 142 and extend in the width direction. A mounting portion 1431 can be formed on the extension plate 143, wherein an energy absorption cavity 145 can be formed between the first plate 141, the second plate 142 and the second beam 112. It can be understood that the cross-section of the energy absorption cavity 145 in the width direction is a triangle, so that the energy absorption cavity 145 can collapse and absorb energy when the vehicle collides with the side, thereby reducing the deformation of the seat cross beam 16.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a first mounting bracket 1111 may be provided on one side of the first beam 111 in the height direction, the first mounting bracket 1111 may be constructed in plurality, and the plurality of first mounting brackets 1111 may be arranged at intervals on the first beam 111, a mounting hole 131 may be formed on the battery pack shell 13, the mounting hole 131 may also be constructed in plurality, the plurality of mounting holes 131 and the plurality of first mounting brackets 1111 may be arranged in one-to-one correspondence, wherein the first mounting bracket 1111 and the mounting hole 131 may be matched with each other by fasteners, specifically, the first mounting bracket 1111 may be arranged on the side of the first beam 111 facing the battery pack shell 13, the fastener may be a structural bolt, and the connection strength between the sill beam and the battery pack shell 13 may be improved by providing the first mounting bracket 1111 and the mounting hole 131.

The floor assembly 10 may also include a reinforcement 17, which may be arranged on the side of the second beam 112 away from the energy absorption cavity 145, and the reinforcement 17 may be connected to the second mounting bracket 1121. In a specific embodiment, the reinforcement 17 may be constructed of extruded aluminum, and the reinforcement 17 may improve the structural strength of the first sill beam 11 and the second sill beam 12. By connecting the reinforcement 17 to the second beam 112 through the second mounting bracket 1121, the stability of the reinforcement 17 during a collision may be improved, and the failure of the reinforcement 17 after tipping over may be avoided. Further, the second mounting bracket 1121 may be constructed as a plurality of second mounting brackets 1121, and the plurality of second mounting brackets 1121 may be arranged at intervals on the second beam 112. The stability of the reinforcement 17 during a collision may be further improved by providing a plurality of second mounting brackets 1121.

Specifically, the floor body 18 and the first threshold beam 11 and the second threshold beam 12 may be fixed by welding. One side of the floor body 18 in the height direction may be in contact with the battery pack housing 13, wherein a seal 181 may be disposed between the floor body 18 and the battery pack housing 13, and the seal 181 may play a role in sealing the floor body 18 and the battery pack housing 13, and the floor body 18 may also be formed with a weight-reducing hole 182 penetrating in the height direction, and the weight-reducing hole 182 may be provided to reduce the weight of the floor body 18, thereby realizing a lightweight design of the floor assembly 10, and the seal 181 may prevent external water from flowing into the cockpit through the weight-reducing hole 182 by sealing the floor body 18 and the battery pack housing 13, thereby realizing the waterproof property of the floor assembly 10.
