[0037] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which 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 drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0038] First, refer to Figures 1 - 5A brief description is given to the front floor assembly 100 according to the embodiment of the second aspect of the present utility model. The front floor assembly 100 includes a front floor 20, a middle channel 30, two connecting longitudinal beams 40, and a reinforcing beam structure 10. The middle channel 30, the two connecting longitudinal beams 40, and the reinforcing beam structure 10 are all disposed on the front floor 20. The middle channel 30 and the two connecting longitudinal beams 40 are both connected to the reinforcing beam structure 10.

[0039] Next, reference is made to Figures 1 - 5 describe the reinforcing beam structure 10 according to the embodiment of the first aspect of the present utility model.

[0040] As Figures 1 - 5 shown, for the reinforcing beam structure 10 according to the embodiment of the first aspect of the present utility model, the reinforcing beam structure 10 is a die-casting part and is an integrally formed part. The reinforcing beam structure 10 includes: a first cross beam portion 11, a second cross beam portion 12, and a first connecting portion 13. Both the first cross beam portion 11 and the second cross beam portion 12 extend along the left-right direction (such as the left-right direction shown in Figure 1 ), and the second cross beam portion 12 and the first cross beam portion 11 are arranged at intervals in the front-rear direction (such as the front-rear direction shown in Figure 1 ); there are two first connecting portions 13, and both of the two first connecting portions 13 are connected between the first cross beam portion 11 and the second cross beam portion 12, and the two first connecting portions 13 are arranged at intervals in the left-right direction.

[0041] In this embodiment, the reinforcing beam structure 10 includes a first cross beam portion 11 and a second cross beam portion 12. The first cross beam portion 11 and the second cross beam portion 12 can provide installation and fixing positions for the assembly of vehicle seats on the front floor assembly 100 and play a good role in structural strengthening. The structure is simple, enabling the vehicle seats to be firmly fixed on the front floor assembly 100. Both the first cross beam portion 11 and the second cross beam portion 12 extend along the left-right direction and are arranged at intervals in the front-rear direction, with a simple structure that meets the fixing requirements of vehicle seats.

[0042] In this embodiment, the reinforcing beam structure 10 is set as a die-casting part and is an integrally formed part. When the reinforcing beam structure 10 is produced and processed, it is integrally die-cast through die-casting equipment, which can well avoid the assembly operations required when the first cross beam portion 11, the second cross beam portion 12, and the first connecting portion 13 in the reinforcing structure are processed separately, can well simplify the production process of the reinforcing beam structure 10, and improve the production efficiency of the front floor assembly 100.

[0043] The reinforcing beam structure 10 is integrally die-cast, which is convenient for processing, making the overall structure of the reinforcing beam structure 10 more compact and having better overall structural strength. The connection between the first crossbeam part 11, the second crossbeam part 12 and the first connection part 13 is more firm, so that the impact force during a collision can be transmitted more stably and reliably. At the same time, the reinforcing beam structure 10 can be processed with a lighter material while meeting the structural strength and usage requirements, and the use of connecting parts is avoided, thus making the weight of the reinforcing beam structure 10 lighter and effectively reducing the overall weight of the front floor assembly 100, so as to well meet the requirements of vehicle lightweighting.

[0044] In this embodiment, there are two first connection parts 13. Both of the two first connection parts 13 are connected between the first crossbeam part 11 and the second crossbeam part 12, and the two first connection parts 13 are arranged at intervals in the left-right direction. The two first connection parts 13 can cooperate to form two stable force transmission paths between the first crossbeam part 11 and the second crossbeam part 12. When a vehicle collides and the impact force is transmitted to the first crossbeam part 11 or the second crossbeam part 12, the force can be stably and quickly transmitted to the second crossbeam part 12 or the first crossbeam part 11 along the two first connection parts 13, so that the force can be evenly dispersed and transmitted in the reinforcing beam structure 10, and to a certain extent, it can better protect the components at the bottom of the front floor assembly 100 and the occupant compartment.

[0045] In this embodiment, the two first connection parts 13 and the first crossbeam part 11 and the second crossbeam part 12 can cooperate to form an opening in the reinforcing beam structure 10. During the die-casting production of the reinforcing beam structure 10, the mold of the die-casting equipment can set the opening position as the ingate. The molten metal can flow from the ingate of the mold to the surrounding reinforcing beam structure 10. Since the ingate is located at a position close to the middle of the reinforcing beam structure 10, when the molten metal flows into the mold from the ingate, it can evenly flow to each area in the reinforcing beam structure 10, so that the molten metal can better fill the mold to die-cast the reinforcing beam structure 10, thus making the overall structural performance of the reinforcing beam structure 10 better and the quality higher.

[0046] When the reinforcing beam structure 10 is die-cast, the ingate can be arranged within the central area range of the reinforcing beam structure 10, making the die-casting area smaller, so that a die-casting equipment with a smaller tonnage model can be selected for production and processing, which can well reduce the production cost of the reinforcing beam structure 10 and make the production cost of the front floor assembly 100 lower.

[0047] According to the reinforcing beam structure 10 of the embodiment of the present utility model, by arranging that both two first connection parts 13 are connected between the first cross beam part 11 and the second cross beam part 12 and are arranged at intervals in the left - right direction, and the reinforcing beam structure 10 is an integrally die - cast part, the production cost of the reinforcing beam structure 10 is lower, and the overall lightweight and structural performance are better.

[0048] In some embodiments of the present utility model, as Figure 2 shown, the first cross beam part 11 is provided with a first arc segment 111, and the second cross beam part 12 is provided with a second arc segment 121. In the left - right direction, the first arc segment 111 extends along an arc convex away from the second arc segment 121, and the second arc segment 121 extends along an arc convex away from the first arc segment 111. Both ends of the first arc segment 111 are respectively connected to one end of the two first connection parts 13, and both ends of the second arc segment 121 are respectively connected to the other end of the two first connection parts 13. The first arc segment 111, the second arc segment 121 and the two first connection parts 13 enclose a through - hole 107.

[0049] In this embodiment, the first cross beam part 11 is provided with the first arc segment 111 extending along an arc, and the second cross beam part 12 is provided with the second arc segment 121 extending along an arc, so that the first cross beam part 11 and the second cross beam part 12 can have better stiffness performance, the first cross beam part 11 and the second cross beam part 12 can better disperse the acting force generated during a collision, and the first cross beam part 11 and the second cross beam part 12 can better support and fix the vehicle seat.

[0050] The first arc segment 111 protrudes away from the second arc segment 121 in the front - rear direction, and the second arc segment 121 protrudes away from the first arc segment 111 in the front - rear direction, so that the connecting longitudinal beam 40 structure can form a partially convex arc structure in the front - rear direction, thereby enabling the reinforcing beam structure 10 to better resist the collision impact force transmitted in the front - rear direction and playing a better role in protecting the safety of the occupant compartment.

[0051] In this embodiment, the first arc segment 111, the second arc segment 121 and the two first connection parts 13 enclose a through - hole 107. The structure is simple, which can meet the need of lightweight, and when the reinforcing beam structure 10 is produced, the ingate can be conveniently arranged at the position of the through - hole 107, so that the structural performance of the reinforcing beam structure 10 after die - casting is better, and a die - casting device with a smaller tonnage can be used for production during die - casting, reducing the production cost of the reinforcing beam structure 10.

[0052] In an embodiment of the present utility model, as Figure 2 shown, in the left - right direction, the surface of one side of the two first connection parts 13 facing the through - hole 107 can be formed as an arc surface convex away from the through - hole 107.

[0053] In this embodiment, the surfaces of the two first connecting portions 13 facing the through hole 107 are formed as arc surfaces protruding away from the through hole 107, which can greatly improve the stiffness performance of the two first connecting portions 13. The through hole 107 defined by the cooperation of the two first connecting portions 13 with the first arc segment 111 and the second arc segment 121 can be formed into a circular or approximately circular structure. The arc surfaces of the two first connecting portions 13 can form a smooth and seamless arc connection with the side wall surfaces of the first arc segment 111 and the second arc segment 121 facing the through hole 107, thereby avoiding large stress concentrations at the connection positions between the two first connecting portions 13 and the first arc segment 111 and the second arc segment 121, and making the overall structural stability and reliability of the reinforcing beam structure 10 better.

[0054] In this embodiment, the two first connecting portions 13 cooperate with the first arc segment 111 and the second arc segment 121 to form a circular or approximately circular through hole 107 structure. When the reinforcing beam structure 10 transmits the acting force generated by a vehicle collision, the reinforcing beam structure 10 can better disperse the acting force, so that the front floor assembly 100 can better protect the occupant compartment and the driver and passengers can obtain better safety protection.

[0055] In one embodiment of the present utility model, as Figure 2 shown, in the left-right direction, the surfaces of the two first connecting portions 13 facing away from the through hole 107 can be formed as arc surfaces protruding towards the through hole 107.

[0056] In this embodiment, the surface of the first connecting portion 13 facing away from the inside of the through hole 107 is formed as an arc surface protruding towards the through hole 107, so that one surface of the first connecting portion 13 can form an arc connection structure with the side wall surface of the first cross beam portion 11 and the side wall surface of the second cross beam portion 12. Thereby, the stress concentration at the connection between the first connecting portion 13 and the first cross beam portion 11 and the second cross beam portion 12 can be further reduced, making the overall structure of the reinforcing beam structure 10 more stable and reliable, and the reinforcing beam structure 10 can better disperse the acting force generated by the collision.

[0057] In some embodiments of the present utility model, as Figure 2 shown, a first flanging 101 can be formed at the lower side edge of the reinforcing beam structure 10, and a plurality of first reinforcing ribs 103 arranged at intervals are provided between the first flanging 101 and the side wall of the reinforcing beam structure 10.

[0058] In this embodiment, a first flanging 101 is formed on the lower side edge of the reinforcing beam structure 10. Specifically, the first flanging 101 can be formed on the circumferential lower side edge of the reinforcing beam structure 10, and the first flanging 101 can also be formed on the lower side edge of the reinforcing beam structure 10 at the through hole 107. The structure of the first flanging 101 is simple, which is convenient for the reinforcing beam structure 10 to be assembled and fixed with the front floor 20 when assembled on the front floor 20.

[0059] In this embodiment, a plurality of first reinforcing ribs 103 arranged at intervals are provided between the first flanging 101 and the side wall of the reinforcing beam structure 10, which can make the first flanging 101 have better structural strength, so that the reinforcing beam structure 10 is more stable and reliable when assembled and fixed with the front floor 20, and can improve the problem of thermal cracking at the rounded corner where the first flanging 101 is connected to the side wall of the reinforcing beam structure 10 during the die-casting production process of the reinforcing beam structure 10, so that the reinforcing beam structure 10 can be die-cast more stably and reliably, and the structural quality and quality are better.

[0060] In an embodiment of the present utility model, the distance between adjacent first reinforcing ribs 103 can be greater than or equal to 10 mm and less than or equal to 50 mm.

[0061] In this embodiment, setting the distance between adjacent first reinforcing ribs 103 to be greater than or equal to 10 mm can make the reinforcing beam structure 10 have sufficient assembly space between adjacent reinforcing ribs for the installation and fixation of the first flanging 101 and the front floor 20 when assembled and fixed with the front floor 20. Setting the distance between adjacent first reinforcing ribs 103 to be less than or equal to 50 mm can make the first reinforcing ribs 103 play an effective role in structurally strengthening the first flanging 101, so as to meet the strengthening requirements of the first reinforcing ribs 103 for the first flanging 101. The shape of the first reinforcing ribs 103 can be triangular or fan-shaped, etc., which is not specifically limited here. For example, the distance between adjacent first reinforcing ribs 103 can be 10 mm, 15 mm, 16 mm, 18 mm, 21 mm, 25 mm, 30 mm, 40 mm, 47 mm, 50 mm, etc. Preferably, the distance between adjacent first reinforcing ribs 103 can be greater than or equal to 20 mm and less than or equal to 30 mm.

[0062] In some embodiments of the present utility model, as Figure 4 and Figure 5 shown, a plurality of second reinforcing ribs 104 arranged in a staggered manner can be provided at the bottoms of the first cross beam portion 11, the second cross beam portion 12 and the first connecting portion 13.

The reinforcing beam structure 10 can support and fix the vehicle seat more stably and reliably, and to a certain extent, the reinforcing beam structure 10 can be lighter in weight while meeting the requirements of structural performance and the like, so as to better meet the requirements of vehicle lightweighting.

[0064] In this embodiment, the plurality of second reinforcing ribs 104 are arranged in a staggered manner, which can provide a good flow channel for the flow and filling of the molten metal during die-casting production of the reinforcing beam structure 10, so that the molten metal can flow more uniformly and stably to each part along the staggered flow channels, thereby enabling the reinforcing beam structure 10 to better carry out die-casting production.

[0065] In some embodiments of the present utility model, such as Figure 2 and Figure 3 shown, the first crossbeam portion 11 and the second crossbeam portion 12 can both be provided with a plurality of vehicle seat mounting holes 171, and the plurality of vehicle seat mounting holes 171 are arranged at intervals in the left-right direction.

The structure is simple, and it can play a good role in structurally strengthening the first crossbeam portion 11 and the second crossbeam portion 12, enabling the reinforcing beam structure 10 to better resist the acting force of vehicle collision.

[0069] The support bosses 17 can provide a stable connection and fixing structure for the installation of the vehicle seat, play a good role in structurally strengthening the assembly and fixing of the vehicle seat and the reinforcing beam structure 10, and enable the vehicle seat to be stably and reliably fixed on the reinforcing beam structure 10. Multiple support bosses 17 cooperate to disperse the weight of the vehicle seat and the driver and passengers to multiple support platform positions, making the overall structural stability of the reinforcing beam structure 10 better.

[0070] In some examples of the present utility model, referring to Figure 1 and Figure 4 as shown, the support boss 17 may form a cavity, and the reinforcing beam structure 10 may further include a reinforcing column 16.

[0071] In this embodiment, a reinforcing column 16 is formed in the cavity of the support boss 17, and the vehicle seat mounting hole 171 penetrates through the reinforcing column 16 in the up and down direction.

The third connection portion 15 and the second connection portion 14 are arranged at intervals in the left-right direction. The third connection portion 15 is adapted to lap-connect with the connecting longitudinal beam 40 of the front floor assembly 100.

[0075] In this embodiment, the second connection portion 14 and the third connection portion 15 are provided on the front side of the first crossbeam portion 11. The structure is simple, facilitating the assembly connection of the reinforcing beam structure 10 with the middle channel 30 and the connecting longitudinal beam 40, enabling the reinforcing beam structure 10 to cooperate with the middle channel 30 and the connecting longitudinal beam 40 to form a stable and continuous force transmission path. The force generated by vehicle collision can be stably transmitted along the middle channel 30 and the connecting longitudinal beam 40 to the reinforcing beam structure 10, so that the front floor assembly 100 can better resist the impact force and play a good role in dispersing the impact force, providing better protection for the passenger compartment.

[0076] In some embodiments of the present utility model, as Figure 2 and Figure 3 shown, a part of the upper surface of the reinforcing beam structure 10 may be formed with reinforcing ribs 106. The number of the reinforcing ribs 106 is multiple. The multiple reinforcing ribs 106 are arranged in an array on the upper surface of the reinforcing beam structure 10 and are connected to each other.

[0077] In this embodiment, the reinforcing ribs 106 are formed on a part of the upper surface of the reinforcing beam structure 10. The multiple reinforcing ribs 106 are arranged in an array and are connected to each other, enabling the reinforcing beam structure 10 to be further structurally strengthened, so that the overall structure of the reinforcing beam structure 10 is more stable. The multiple reinforcing ribs 106 are connected and arranged, which can provide more flow paths for the flow and filling of the molten metal during the die-casting production of the reinforcing ribs, so that the reinforcing beam structure 10 is more efficient and has more stable forming during production and processing.

[0078] For example, two, three, four, five, etc. reinforcing ribs 106 can be provided. The arrangement position and range of the reinforcing ribs 106 can be reasonably set as required. The shape of the reinforcing ribs 106 can be hexagonal or rhombic, etc., so that the reinforcing ribs 106 can better improve the stiffness performance of the reinforcing beam structure 10 and achieve a relatively uniform structural strengthening effect, making the vehicle seat more stable after being assembled on the reinforcing beam structure 10.

[0079] In an embodiment of the present invention, the thickness of the reinforcing rib 106 can be greater than or equal to 0.2 mm and less than or equal to 3 mm.

[0080] In this embodiment, setting the thickness of the reinforcing rib 106 to be greater than or equal to 0.2 mm and less than or equal to 3 mm can enable the reinforcing rib 106 to play a stable and reliable role in structural strengthening, and avoid the weight increase caused by the excessive thickness of the reinforcing rib 106, meeting the needs of vehicle lightweighting. For example, the thickness of the reinforcing rib 106 can be 0.2 mm, 0.3 mm, 0.5 mm, 1 mm, 2 mm, 2.6 mm, 3 mm, etc.

[0081] In some embodiments of the present invention, referring to Figure 1 As shown, the reinforcing beam structure 10 can be symmetrically arranged about the midline of the reinforcing beam structure 10 in the front-rear direction in the left-right direction. This can simplify the production design of the reinforcing beam structure 10, facilitate the production and manufacturing of the reinforcing beam structure 10, and enable the reinforcing beam structure 10 to have better stiffness performance and better structural performance, making the stress distribution and the load borne in the reinforcing beam structure 10 more uniform, thereby making the stability and reliability of the reinforcing beam structure 10 better, and enabling the front floor assembly 100 to provide better safety protection for the occupant compartment.

[0082] In some embodiments of the present invention, the reinforcing beam structure 10 can be an aluminum alloy part, or the reinforcing beam structure 10 can be a magnesium alloy part.

[0083] In this embodiment, setting the reinforcing beam structure 10 as an aluminum alloy part or a magnesium alloy part can meet the needs of die-casting production and make the weight of the reinforcing beam structure 10 lighter, thus well meeting the requirements of the structural strength of the front floor assembly 100 and the requirements of vehicle lightweighting.

The middle channel 30 extends in the front-rear direction and is disposed on the front floor 20; the two connecting longitudinal beams 40 are respectively arranged on both sides of the middle channel 30 in the left-right direction, and the connecting longitudinal beam 40 extends in the front-rear direction and is disposed on the front floor 20.

[0086] In this embodiment, the two connecting longitudinal beams 40 are arranged on both sides of the middle channel 30 in the left-right direction and are fixedly assembled with the front floor 20, which can play a very good role in strengthening the structure of the front floor assembly 100, and can form a good force transmission path, so that the front floor assembly 100 can better resist and disperse the impact force during vehicle collision. The setting of the middle channel 30 in this embodiment can meet the use needs of the vehicle.

A reinforcing rib 106 is formed on the upper surface of the reinforcing beam structure 10, and a plurality of second reinforcing ribs 104 arranged in a staggered manner are formed at the bottom of the reinforcing beam structure 10. A first flanging 101 is formed at the lower side edge of the reinforcing beam structure 10, and a first reinforcing rib 103 arranged at intervals is formed between the first flanging 101 and the side wall of the reinforcing beam structure 10. The first flanging 101 is welded or riveted to the front floor 20. The reinforcing beam structure 10 is symmetrically arranged about the mid - line of the reinforcing beam structure 10 in the front - rear direction in the left - right direction.

[0097] Both the first cross - beam portion 11 and the second cross - beam portion 12 extend in the left - right direction and are arranged at intervals in the front - rear direction. The first cross - beam portion 11 is arranged in front of the second cross - beam portion 12. A second connecting portion 14 and two third connecting portions 15 are formed on the front side of the first cross - beam portion 11. After the second connecting portion 14 is overlapped and connected with the middle channel 30, it is riveted or welded. After the third connecting portion 15 is overlapped and connected with the connecting longitudinal beam 40, it is riveted or welded. Second flangings 102 are formed at both ends of the first cross - beam portion 11 and the second cross - beam portion 12 in the left - right direction, and the second flangings 102 are formed as sill connection ends to be assembled and fixed with the sill of the vehicle.

[0098] Two first connecting portions 13 are connected between the first cross - beam portion 11 and the second cross - beam portion 12.

The first connecting portions 13 and the first cross - beam portion 11 and the second cross - beam portion 12 cooperate to form a U - shaped hole on the side of the through - hole 107 in the left - right direction.

[0099] The first crossbeam portion 11 is formed with four support bosses 17, and the four support bosses 17 are arranged at intervals in the left - right direction.
