[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1-3 The seat mounting structure 100 according to a first aspect embodiment of the present invention is described.

[0031] like Figure 1 and Figure 2 As shown, the seat mounting structure 100 according to the first aspect of the present invention includes: a seat crossbeam 10 and a first reinforcing plate 20.

[0032] Specifically, the seat crossbeam 10 extends along the width direction of the vehicle and is adapted to be connected to the vehicle floor. The first reinforcing plate 20 is disposed between the seat crossbeam 10 and the vehicle floor. The first reinforcing plate 20 is connected to the seat crossbeam 10 and cooperates to define a first reinforcing cavity. The battery pack mounting component is adapted to pass through the mounting hole on the vehicle floor and be connected to the first reinforcing plate 20.

[0033] After the vehicle is assembled, the seat beam 10 is installed on the vehicle floor, the battery pack is installed on the underside of the vehicle floor, the mounting component is connected to the battery pack, and the mounting component passes through the mounting hole on the vehicle floor and is connected to the first reinforcing plate 20.

[0034] Understandably, the weight of the battery pack exerts a force on the seat crossbeam 10 towards the vehicle floor. When the vehicle is subjected to a side impact, under the influence of the impact force along the width of the vehicle and the supporting force of the vehicle floor, the seat crossbeam 10 will tend to bend upward in the middle. At this time, under the influence of the weight of the battery pack, the downward force of the battery pack on the seat crossbeam 10 can offset part of the force that causes the seat crossbeam 10 to bend. Thus, the degree of deformation of the seat crossbeam 10 can be reduced and the bending resistance of the seat crossbeam 10 can be improved.

[0035] The first reinforcing plate 20 can provide an installation position for the battery pack mounting components, and the first reinforcing cavity defined between the first reinforcing plate 20 and the seat crossbeam 10 can enhance the structural strength of the first reinforcing plate 20 and improve the reliability of the battery pack installation on the vehicle body.

[0036] Preferably, the first reinforcing plate 20 has a through hole connected to the first reinforcing cavity, and the mounting component is a bolt. The battery pack is connected to the first reinforcing plate 20 through the bolt and the through hole.

[0037] According to the first aspect embodiment of the present invention, the seat mounting structure 100 is connected to the seat crossbeam 10 via a battery pack. When the vehicle is subjected to a side impact, the force exerted by the battery pack on the seat crossbeam 10 toward the vehicle floor can reduce the degree of deformation of the seat crossbeam 10 away from the vehicle floor, thereby improving the bending resistance of the seat crossbeam 10. Furthermore, the first reinforcing plate 20 and the first reinforcing cavity can improve the structural strength at the connection between the battery pack and the seat crossbeam 10.

[0038] In some embodiments of this utility model, such as Figure 1 As shown, a receiving groove 11 extending along the width direction of the vehicle is formed on the lower side of the seat crossbeam 10, and the first reinforcing plate 20 cooperates with the inner wall of the receiving groove 11 to define the first reinforcing cavity.

[0039] After the seat crossbeam 10 is installed on the vehicle floor, the receiving groove 11 can cooperate with the vehicle floor to form a reinforced cavity, thereby further improving the bending resistance of the seat crossbeam 10.

[0040] Furthermore, the receiving slot 11 can provide a receiving space for the first reinforcing plate 20, so that the first reinforcing plate 20 can be properly arranged between the seat crossbeam 10 and the vehicle floor.

[0041] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the receiving groove 11 has a mounting groove connected to the receiving groove 11 on one side edge in the length direction of the vehicle. The first reinforcing plate 20 includes a first part 21 and a second part 22 connected in the length direction of the vehicle. The first part 21 is disposed in the mounting groove, and the second part 22 is disposed in the receiving groove 11. The edge of the second part 22 is connected to the bottom wall of the receiving groove 11 to cooperate in defining the first reinforcing cavity.

[0042] The first part 21 is connected to the side wall of the mounting groove. During the production process, the mounting groove can position and limit the first reinforcing plate 20. On the one hand, it can quickly place the first reinforcing plate 20 into place. On the other hand, during the process of connecting the first reinforcing plate 20 and the seat crossbeam 10, the first reinforcing plate 20 is less likely to be displaced, thereby reducing the production difficulty and improving the positional accuracy of the first reinforcing plate 20 on the seat crossbeam 10.

[0043] Preferably, the first reinforcing plate 20 is welded to the seat crossbeam 10.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the seat crossbeam 10 includes: a crossbeam body 12 and a second reinforcing plate 13. Both the crossbeam body 12 and the second reinforcing plate 13 extend along the width direction of the vehicle. The two sides of the second reinforcing plate 13 in the width direction are connected to the crossbeam body 12 to define the second reinforcing cavity 14.

[0045] The first reinforcing plate 20 is connected to the second reinforcing plate 13. By setting the crossbeam body 12 and the second reinforcing plate 13, and defining the second reinforcing cavity 14 between the crossbeam body 12 and the second reinforcing plate 13, the structural strength of the seat crossbeam 10 can be enhanced, thereby further improving the bending resistance of the seat crossbeam 10.

[0046] Preferably, the second reinforcing plate 13 is welded to the crossbeam body 12.

[0047] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a portion of the lower surface of the crossbeam body 12 is recessed to form a first groove extending along the width direction of the vehicle. The second reinforcing plate 13 includes a plate body extending along the width direction of the vehicle. The two sides of the plate body in the width direction are formed with downwardly folded edges. The second reinforcing plate 13 is disposed in the first groove, and the folded edges are connected to the two sides of the first groove in the length direction of the vehicle. A second reinforcing cavity 14 is defined between the plate body and the inner wall of the first groove. The folded edges cooperate with the plate body to define a receiving groove 11.

[0048] The folded edge has an outwardly folded edge that overlaps and connects to the edge of the first groove. By providing receiving grooves 11 and second reinforcing cavities 14 on both sides of the second reinforcing plate 13, a two-layer reinforcing cavity structure can be formed inside the seat crossbeam 10 after it is installed on the vehicle floor. This further improves the structural strength of the seat crossbeam 10 and thus further enhances its bending resistance.

[0049] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the seat mounting structure 100 also includes a connecting longitudinal beam 30, which extends along the length of the vehicle. One end of the connecting longitudinal beam 30 is connected to the middle of the seat crossbeam 10, and the connecting longitudinal beam 30 is adapted to be connected to the vehicle floor.

[0050] When a vehicle is subjected to a side impact, under the impact force in the width direction of the vehicle and the supporting force of the vehicle floor, the seat crossbeam 10 will have a bending tendency with the middle part bulging upward. At this time, the connecting longitudinal beam 30 connecting the vehicle floor and the seat crossbeam 10 can exert a force on the seat crossbeam 10 towards the vehicle floor. Under the action of the weight of the battery pack and the tension of the connecting longitudinal beam 30, the force exerted by the battery pack and the connecting longitudinal beam 30 on the seat crossbeam 10 can offset part of the above-mentioned force that causes the seat crossbeam 10 to bend. Thus, the degree of deformation of the seat crossbeam 10 can be further reduced and the bending resistance of the seat crossbeam 10 can be improved.

[0051] Preferably, the connecting longitudinal beam 30 is welded to the seat crossbeam 10.

[0052] In some embodiments of this utility model, such as Figure 3 As shown, the middle part of the seat crossbeam 10 protrudes upward to form a clearance passage 15 that runs through the length of the vehicle.

[0053] The clearance passage 15 provides clearance space for the wiring harness passage on the vehicle floor. Meanwhile, the middle part of the seat crossbeam 10 protrudes upward, which can create a reinforcing structure in the middle of the seat crossbeam 10, thereby further improving the bending resistance of the seat crossbeam 10.

[0054] In some embodiments of this utility model, such as Figure 1 As shown, the seat mounting structure 100 also includes a third reinforcing plate 40, the middle of which protrudes to form a reinforcing protrusion. The third reinforcing plate 40 is connected to the seat crossbeam 10. The reinforcing protrusion is located in the clearance channel 15, and the reinforcing protrusion and the inner wall of the clearance channel 15 cooperate to define a third reinforcing cavity.

[0055] By setting a third reinforcing plate 40, the structural strength of the middle part of the seat crossbeam 10 can be enhanced. It is understood that when the vehicle is subjected to a side impact, the middle part of the seat crossbeam 10 is more likely to deform under the compression of the side of the vehicle body. Therefore, enhancing the structural strength of the middle part of the seat crossbeam 10 can further improve the bending resistance of the seat crossbeam 10.

[0056] Preferably, there are two second reinforcing plates 13, which are respectively disposed on both sides of the clearance passage 15, and the two ends of the third reinforcing plate 40 are respectively connected to the two second reinforcing plates 13.

[0057] Preferably, the crossbeam body is made of CA1000 / 1400CHS hot-formed steel and has a thickness of 1.8mm. The second reinforcing plate 13 has a thickness of 1.6mm and is also made of CA1000 / 1400CHS hot-formed steel. The first reinforcing plate 20 has a thickness of 1.5mm and is made of CA340 / 590DP steel.

[0058] In some embodiments of this utility model, such as Figure 3 As shown, the seat mounting structure 100 also includes a connecting plate 50, which is located at the end of the seat crossbeam 10 and is used to connect to the side panel of the vehicle body.

[0059] Preferably, the connecting plate 50 is made of CA340 / 590DP material.

[0060] By setting the connecting plate 50, on the one hand, it is convenient to connect the seat crossbeam 10 with the side wall, and on the other hand, the connecting plate 50 can improve the structural strength of the connection between the seat crossbeam 10 and the side wall.

[0061] The vehicle according to a second aspect of the present invention includes: a vehicle body floor, a battery pack, a mounting component, and the seat beam 10 mounting structure described above according to a first aspect of the present invention.

[0062] Specifically, the battery pack is located on the underside of the vehicle floor, and a through mounting hole is formed on the vehicle floor. The mounting component is connected to the battery pack, the seat beam 10 is connected to the vehicle floor, and the mounting component passes through the mounting hole and is connected to the first reinforcing plate 20.
